Andrew Jackson: Tyrant

â€Å"When the 1828 election rolled around, a lot of people were terrified when they heard Andrew â€Å"Old Hickory† Jackson was running. If you're wondering how a guy we're calling a bad ass got such a lame nickname, it's because he used to carry a hickory cane around and beat people senseless with it, and if you're wondering why he did that, it's because he was a f#$%*in g lunatic. † (Daniel O’Brien February 15, 2008) This quote from cracked.com illustrates the depth of the ruthlessness within Andrew Jackson, and it is this callousness that made him a tyrant of a President.His decisions were calculated. Andrew Jackson was known to be the type of person who would put his friends into government as a reward instead of the people who would actually be good for the job. This was called the Spoil System. The main purpose for the Spoil System was to ensure that when the party control changed, so did the administrators.Andrew Jackson was also known for taking advantag e of his power in the executive branch, while ignoring the Judicial and Legislative branches. He abused his power to veto to try to make himself more powerful than congress, and he ended up using the veto about sixteen times. Andrew Jackson was who started the act that moved thousands of Indian families to Oklahoma. This displacement was what became known as the â€Å"Trail of Tears. † The Natives were forced to walk across the country during the winter with nothing but clothes, where nearly 2000 Native Americans died.Jackson must have thought it was okay for him to evict them because of his thought to designate their own land to live on, even though the Native had so many advances in becoming civilized so they could be accepted by him and other citizens. Andrew Jackson was one of the biggest slave owners in the south and he was a big believer in Manifest Destiny, which he supported the right of whites to conquer North America. Jackson was also known for breaking campaign pol icies.He had stated that he supported state government, but ended up expanding federal government and that caused a lot of controversy. A good president would not jeopardize the lives of innocent people or try to steal power to make himself the center of the government. A good president wouldn’t put himself before his own people. For these reasons I believe that even though Jackson may have done some things to help our country, overall he was a horrible president.

The interviews addressed buying attitudes

OBJECTIVE: Compulsive buying (uncontrolled urges to buy, with resulting significant adverse consequences) has been estimated to affect from 1. 8% to 16% of the adult U. S. population. To the authors’ knowledge, no study has used a large general population sample to estimate its prevalence. METHOD: The authors conducted a random sample, national household telephone survey in the spring and summer of 2004 and interviewed 2,513 adults.The interviews addressed buying attitudes and behaviors, their consequences, and the respondents’ financial and demographic data. The authors used a clinically validated screening instrument, the Compulsive Buying Scale, to classify respondents as either compulsive buyers or not. RESULTS: The rate of response was 56. 3%, which compares favorably with rates in federal national health surveys. The cooperation rate was 97. 6%. Respondents included a higher percentage of women and people ages 55 and older than the U.S. adult population. The estim ated point prevalence of compulsive buying among respondents was 5. 8% (by gender: 6. 0% for women, 5. 5% for men). The gender-adjusted prevalence rate was 5. 8%. Compared with other respondents, compulsive buyers were younger, and a greater proportion reported incomes under $50,000. They exhibited more maladaptive responses on most consumer behavior measures and were more than four times less likely to pay off credit card balances in full.CONCLUSIONS:A study using clinically valid interviews is needed to evaluate these results. The emotional and functional toll of compulsive buying and the frequency of comorbid psychiatric disorders suggest that studies of treatments and social interventions are warranted Source: American Journal of Psychiatry: http://ajp. psychiatryonline. org/cgi/content/abstract/163/10/1806

Sannu’s Story

Unit 8. Case Study 1. Sannu’s Story Sannu has contracted Leprosy. As a sixteen year old teenager, it is hard to pin point when he was infected since Leprosy has a long incubation period. As a small boy traveling barefoot along trails in his village, Sannu’s body has already adapted to his living conditions. Sannu’s feet are tough and calloused. As Sannu ages, so does his Leprosy infection progress. The infection will cause neuropathy in his extremities which will lead to many injuries to his feet and hands. The wounds acquired will be infected for weeks or even months without treatment.The neuropathy caused by the Leprosy infection is characterized by causing a decrease in sensation in the extremities, muscle weakness, and numbness. Sannu’s feet that have been toughened by his environment and life style have been further injured due to lack of sensation and medical treatment. In an attempt to keep his feet clean to aide the healing of his infections, Sannu is more than likely maintaining a sedentary life style. This life style along with the progression of the Leprosy infection will weaken Sannu’s muscles. A feature common to all forms of Leprosy is nerve infection.Nerve damage appears to result from the multiplication of bacilli within Schwann cells and damage to the perineurium. Most of the deformities occurring from Leprosy are in fact due to trauma or a secondary infection. In a Leprosy infection one of the first symptoms are anesthesia to heat and cold. Leprosy affects the peripheral nervous system by attacking the myelin sheath surrounding the axons which affects the reliability and speed of nerve impulses. In other words, the nerve fibers are no longer insulated and nerve impulses cannot be conducted efficiently.There are different types of sensory receptors located throughout the body and are designed based on a selective stimulus response. The appropriate receptive field is stimulated within a sensory receptor produci ng a response. In Sannu’s condition this action is delayed or absent due to the damage of his free nerve endings. Free nerve endings detect pain, temperature, and touch as well as tickle and itch. Sannu’s encapsulated nerve endings are also damaged. Encapsulated nerve endings detect pressure, vibration, and touch sensations.When Dianna performed the tests to check Sannu’s Achilles tendon and Babinski’s reflex, she was evaluating his somatic senses. Somatic senses involve sensations such as touch, pressure, and pain as well as temperature perception. These are all affected in Leprosy infection. In Sannu’s case he has also lost the sensations of touch, pressure, and pain in his feet and hands due to the affects of leprosy on his nociceptors, mechanoreceptors, proprioceptors, and exteroceptors. These sensations are also present in the sensory receptors free nerve endings and encapsulated nerve endings.Sannu’s interoceptors would not be affected in a Leprosy infection because interoceptors pertain to the body’s internal environment. Mycobacterium leprae grow best in relatively cool areas of the body such as: the skin, peripheral nerves, the mucosa of the upper respiratory tract as well as the chamber of the eye and in severe untreated cases the testes and eventually other vital organs. Leprosy affects the exteroceptors of the external surface of the body. Nociceptors are the receptors of pain and are located in all tissues of the body with an exception of the brain.Proprioceptors do no adapt very much, this is why Sannu still feels pain in his leg that has been amputated. Sannu’s pain is slow pain. Slow pain is referring to pain that is chronic, burning, aching, or throbbing. The peripheral receptors activated during a stimulus are the nociceptors. Like other cutaneous and subcutaneous receptors, Nociceptors transduce a variety of stimuli into receptor potentials. Also, like other somatic sensory receptors, N ociceptors arise from cell bodies in dorsal root ganglia that send one axonal process to the periphery and the other into the spinal cord or brain stem.Peripheral Nociceptors terminate at the site of free nerve endings. Nociceptors are located in the entire body except for the brain. The loss of myelination causes impulses to misfire. Without the myelin sheath the impulses are slower and misdirected. Sannu had little sensation to his extremities because of the process related to his Leprosy infection. Phantom limb pain is a result of neuroplasticity (new neural links can be made), or the brain region that once was responsible for controlling the amputated limb is taken over by an adjacent area of the brain.The phantom limb pain is enhanced by referred sensations, so that stimuli applied to other body parts can be sensed from the phantom limb. In patients with Leprosy, phantom limb pain will not occur with only the amputation of fingers, toes, hands, or feet. Phantom limbs and phanto m limb pain will only occur when the amputation is taken up to the stump of that limb. The representation of Sannu’s amputated leg on the somatosensory map will involve referred sensations because of remapping of somatosensory areas in the brain. The activity of the somatosensory map in the brain leads to conscious experience of body image and somatic sensations.After Sannu’s amputation it is possible for him to initially experience some effects on his balance and equilibrium. This is because after amputation Sannu may still have confused senses of his missing leg. With the introduction of a prosthesis, Sannu’s brain will connect to the prosthetic device causing his brain to remember how to function as if the original leg were still there. The initial sensory loss that Sannu experienced was due to interference of the sensory pathway transmission. Leprosy affects the skin and peripheral nerves which are closest to the exterior of the body where the sensory recept ors are located.Leprosy infection is caused by mycobacterium leprae and mycobacterium lepromatosis. Both forms affect the peripheral nervous system by attacking the Schwann cells, destroying the myelin. At the site of the Schwann cell, the bacteria multiply and cause damage of the nerve architecture and cause secondary inflammation. This disease process results in desensitizing sensory receptors. This is why when Sannu cut his foot, he did not feel the pain, nor the infection that followed. Due to his location in a remote village and lack of medical care, his infection resulted in an amputation.The receptors that should have sensed the initial injury to Sannu’s foot are the exteroceptors. Exteroceptors are responsible for responding to stimulus from outside the body such as touch, pressure, pain, and temperature. After Sannu’s amputation he began experiencing phantom limb sensations. This is considered as a form of neuropathic pain. It is presumed to be a response by t he peripheral nervous system and the central nervous system of an injury. The process of reorganizing occurs from retained nerves from the amputated limb, spinal cord, thalamus, and cerebral cortex.After an amputation the area of the brain that is responsible for processing the sensations from the missing limb are taken over by areas that neighbored the missing limb. It is believed that around 95% of people are naturally immune to Leprosy. Recent research suggests that there is a defect in cell-mediated immunity that causes susceptibility to Leprosy. The area of DNA responsible for that variable is also found in Parkinson’s disease. It is speculated the two disorders are linked somehow at the biochemical level. Research has shown that susceptibility to the disease was linked to region q25 on the long arm of chromosome 6.Further study indicated that the Leprosy susceptibility gene lies within a region shared by two genes for Parkinson’s disease.

Supply Chain Essay Example | Topics and Well Written Essays - 1000 words - 1

Supply Chain - Essay Example Supply Chain The role of international supply chain management is significant amongst organizations in the present scenario. Increased globalization is the major reason behind such form of supply chain management. It can be stated that this form of trend has given birth to increasing sourcing through cross-border activities (Farmer and Jessop, 2008). On the other hand global supply chain even enables firm to acquire certain parts of the value chain offered by low cost providers. This increasing rate of global operations has even enabled global coordination amongst firms. In present decade it is observed that many larger organizations work in collaboration with SMEs due to the support provided by such international supply chain activities (Lysons and Farrington, 2005). The framework of international supply chain management has been beneficial for larger and mid-sized organizations and even for manufacturers as they are able to develop larger lot sizes, better environments and much lower tax rates for their product line. Amongst organizations this framework plays an active role by not only storing large base of resources but even through effective customer service management, management of manufacturing flow, product commercialization and development, maintaining supplier relationship, handling returns and successfully fulfilling placed orders

Orientation Phase of Nursing Essay Example | Topics and Well Written Essays - 500 words - 17

Orientation Phase of Nursing - Essay Example The stages of interpersonal relationships were initially four that include orientation, identification, exploitation, and resolution phases. However, the steps later reduced to three after further studies and analysis. The second phase now combined both the identification and exploitation phases. These two aspects combined, therefore, became known collectively as the working phase. This paper, however, only discusses the orientation phase. This is the first phase of the interpersonal process as was explained by Peplau. It is at this stage where the patient first meets the nurse. At this point, the nurse and patient are still total strangers. This first meeting always brings with it a lot of anxieties, from both the nurse and the patient. It is the nurse’s responsibility to alleviate the anxiety that grips them before proceeding any further (Boyd, 2007). This is important in establishing a therapeutic environment. Mary Boyd states that this is the session where the nurse discusses the patient’s expectations and explains the purpose of their relationship. It gives a clear definition of the roles, goals, and limitations of the relationship. In short, the nurse sets limits that have to adhere to throughout the relationship. The boundaries are however subject to flexibility depending on the situation. In practical situations where the nurse has to draft a session attendance schedule for the patient, the nurse should also spell out the guidelines on how to handle cases of missed sessions and lateness.  Ã‚   The handling should be in such a way that it alienates the patient. The nurse should understand that this could be a means by which the patient tests the relationship (Boyd, 2007). It is important to gain the patient’s acceptance and develop trust. This is achieved by maintaining consistency and continually encouraging the patient, both verbally and non-verbally, to express themselves.

What is a Case Study & The Techniques In Active Reading Essay

What is a Case Study & The Techniques In Active Reading - Essay Example Historical Significance: the Case study is not a new trend. It goes back to 1829 when Frederic Le Play first introduced this methodology of testing hypotheses. However, in the current day world, the popularity of case study method is increasing day by day. This methodology is commonly used in social science subjects like sociology, psychology, and anthropology for educational evaluation. In business and legal education, these case studies are most often used as teaching methods for professional development. Furthermore, in the field of medicine, this methodology is used by physicians where they want to collect and share data or information. So, the purpose of the case study, as a research strategy, is to investigate a factor happening within its real context or we can say case study offers more thorough analysis of the situation. It is an analytical piece that involves heavy research and application of concepts, knowledge, and theories. Case studies rely on quantitative evidence, multiple sources of facts and data that further benefit in the development of theoretical proposals. When we talk about case study writing, we can see that there are three major steps including research, analysis and finally the actual writing. The research phase can be completed through libraries and internet and by interviewing people. Secondly, all the information gathered from various sources including articles, books, and people, is organized to highlight the focus of study and thoroughly analyzed. Finally, the case is written. When we talk about case studies, we can see that case study text is of prior importance in case study writing. The text is a collection of written words. Remember, a single word sounds nothing until or unless it becomes the part of a text. Text lies within a situation that offers it a unique meaning.

L-12 Coursework Example | Topics and Well Written Essays - 500 words

L-12 - Coursework Example Firstly, the aim of this decision is to ensure that the law practices fairness to both parties. That is, since the victim has been deprived of his or her ample life, then the fairest act to sentence the culprit to a lifetime imprisonment. Secondly, decision is motivated by the notion of ensuring that, any other Juvenile with a plan to commit murder will be totally warned and discouraged from performing such a heinous act. Whenever one intends to commit a sin and sees the punishments a fellow sinner is going through, then, there are great chances that he or she will drop the heinous intentions. Finally and yet importantly, the decision is driven by the idea of ensuring that murder cases are given significantly heavy weight. Sentencing a murderer into lifetime imprisonment despite a culprit’s age sends a clear message to the public that the act of murder is completely intolerable in all aspects of life. Right from the post’s outset, it is sincerely clear that the subject of intentionally killing another person is matter where a second chance to the culprit is something next to impossibility. In essence, it is considerably important to make it clear that I agree with the post. That is, I support the idea that young murderers should be sentenced into lifetime imprisonment. Psychologically, at the very early age of a human beings development, one of the key lessons that get into one’s brain is that some things are harmful. In fact, at that early age, one automatically learns most of the activities or issues that can make him or another feel lightly or severely injured. At the juvenile age (seventeen years and below), it is essential to note that a young person clearly knows what he or she does. That is, before he gets to commit a murder, the first thing is that he understands that a gun shot or any other killing method will lead to causing great injuries (even death) to an individual. Therefore, even a young murderer sincerely

'NGOs legitimacy and representation at the global level' Literature review

'NGOs legitimacy and representation at the global level' - Literature review Example ons and an annual addition of 1200 new ones (Yearbook of international organizations, 2013).This essay seeks to examine the concepts of legitimacy and representation of these NGOs at the global level. In addition, the essay intends to find out the ways in which accountability and representation can be enhanced. As a point of departure, a pressing question on the legitimacy and present political debate on reclaiming the democratic projects in the context of globalization has arose and it needs to be answered. Numerous institutions and scholars have always argued out the extent to which these NGOs are legitimate, responsible and answerable (MACDONALD, 2008). These aspects directly affect the subjects. For instance, the reason for the recent mounting of pressure of high profile campaigns for democratization of powerful international organizations such as the IMF and world Bank includes the belief that, these organizations are neither not representatives of the subjects, nor do they exhibit the aspects of accountable bodies. Montesquieu, a balanced democrat argues that any leadership that is a representative of subjects must get consent of the governed. This follows that, a legitimate NGO should be attributed to the consent of the governed either through elections or by acclamation. This follows that, democracy is exhibited in these institutions if Montesquieu principle is applied (LOY, 1968). On the other hand, Locke confirms that the aspect of legitimacy must be derived from the subjects and once a legitimate body has been consented, then subjects have a preserve of their rights through these bodies. Locke believes that, the interests of the subjects must come first before personal interests (LOCKE, 1990). The question that arises is that who bestows responsibilities to NGOs and how representation of citizens is gained? This follows that, the aspect of representation is challengeable. Despite MACDONALD’s assertion that, alternative non-electoral mechanism of

Japanese Internment Essay Example | Topics and Well Written Essays - 1000 words - 2

Japanese Internment - Essay Example The article provides valuable perceptions and insights about what the Japanese went through during the internment(Flamiano,2000, pp.22). The United States entered into World War II after the Japanese Navy attacked Pearl Harbour in 1941. According to Dolores the anti Japanese criteria, then gripped the home front. She states that president Franklin signed an executive order which authorized the war department to exclude any group of people from the military areas for the duration of the war. A hundred and ten thousand Japanese immigrants and Americans from the west coast were evacuated at that time. Their lives were disrupted since they had to stop living their normal lives and move to other areas. The Japanese Americans were falsely accused of sending signals to their countries. Dolores states that three priests were arrested and the reporters gave a false report. Dolores explains that the Japanese continued to follow their traditions while still in America. She quotes a California governor saying that it would be impossible to tell whether the Japanese are loyal or not. She states that they faced racism in America w hereby all Asian immigrants were considered aliens in the United States. Internment photography begun in the 1970s as scholarly analysis with a strong focus being on the Manzanar photographs of Asel Adams and Dorothea Lange. Many scholars, however, neglected the magazine photography in order to study the ones in museums or the government archives. Dolores states that Adam’s work that contained eight photographs shared a vision that the camp was tough to live in for people of Manzarin An example, as Dolores explains, was a photo of Collier that portrayed opportunities for people who were ready to work. In 1980 and 2004, Elena Tajima and Sylvia Danovitch noticed that the internment photographs excluded the harshness or inconvenience of the camp’s living conditions. An example is Colliers’s photo of two women with checkered curtains at their

European Construction and Property Essay Example | Topics and Well Written Essays - 2000 words

European Construction and Property - Essay Example The first part of this report attempts to assess the scope and value of the Bulgarian construction market comparing it with the UK. The second part of the report focuses on the scope for service integrators or managers that manage the operational service procurement for their customers in the construction industry, especially in the residential and office building sector. Bulgaria is situated in the South-East Europe, on the Balkan Peninsula, and is one of the oldest European states. To the south it borders with the Republic of Turkey and the Republic of Greece, to the west - with Former Yugoslav Republic of Macedonia and the Federal Republic of Yugoslavia. The Danube River is the natural north border with the Republic of Romania, and to the east Bulgaria borders on the Black Sea. It is characterized by an extremely varied terrain: huge plains and lowlands, high and low mountains, plateaus, caves, basins and gorges. The lowest altitude is 0 metres (at Black Sea), the highest altitude is 2925 metres (the peak of Mussala in the Rila mountain). It has favourable position in terms of location from national and international perspective, and easy accessibility by air, rail and road. Encompassing just 2 % ... Bulgaria is a country of tranquil, ecologically clean, distinctive places of interest, where one can be absorbed by the traditional Bulgarian customs and culture at the same time. Capital Sofia (pop. 1.2 million) is a vibrant city thriving on expansion, architectural buildings and deep respect for multi-cultural diversity. The Black Sea coastal stretch faces east and extends over 378 km, its seawater clean and not tidal and its vast beaches covered with fine golden sand. The majority of Bulgaria beaches have been awarded the EU Blue Flag for their environmental excellence. The conditions for investments in the real estates sphere in Bulgaria have never been better. Bulgaria is a country of unlimited possibilities and it is the time to be first. Bulgaria is the newest hot destination for the real estate market in Europe. CONSTRUCTION INDUSTRY IN BULGARIA - AN OVERVIEW Over 36,000 construction companies are registered in Bulgaria, 2,400 of which can be classified as medium and a few as large-sized. The volume of building and construction activities amounts to 2,500 million Euros per annum and the industry has a 5 % share in Bulgaria's GDP, which is expected to double over the next two years. Estimated annual growth is 15%. The sector employs some 120,000 people. Smaller companies have tended to merge into large joint-stock companies and consortiums, particularly seeking foreign technologies and management expertise. Bulgaria has been receiving large amount of donor aid and PHARE/ ISPA funds for infrastructure projects, the implementation of some of which will continue until 2008. Major road/ railroad, waste disposal, water/waste-water and landslide stabilisation projects are expected to be

The education system Essay Example for Free

The education system Essay Assess the view that ethnic minority pupils are discriminated against in the education system There are currently significant differences in the educational attainment of ethnic minority pupils compared to their white peers, as shown in the statistics from Social Trends. There are many possible factors that may account for this and for the purposes of this essay I will explore the idea of discrimination against ethnic minority pupils. Some pupils may be treated differently either due to racism or inaccurate views made by the teachers which lead to labelling. The Swan Report was done in 1985 in Britain after it was felt that research should be conducted into the differing attainments of ethnic minority pupils. This report concluded that there was not much racism in Britain at that time and if there was, it may have been from resources such as books so is consequently dying out. Due to the age of the Swan Report, its findings may not be as valid today, so this would indicate that the amount of racism, if any, would have decreased dramatically. It would therefore, be fair to say that the changes in the attitudes of people in society has lead to ethnic minority pupils no longer being discriminated against. However, Coard felt that there was racism being put through the ethnocentric education, it focused on white people, so it caused racism from the teachers and peer groups. This view argues that ethnic minority pupils are being discriminated against, but I feel it is difficult to state whether this is knowingly happening. For example, there is a wide range of ethnic minority pupils from a range of backgrounds in Britain today so it would be impractical to include work that is related to all of the cultures. As we all live in England it seems natural to give slightly more attention to the history of this country. Also, an explicit criticism of Coards work would be that it is not scientific as it is only based on his views. Overall, I feel that what Coard has described is not discrimination, but he has simply looked at the education system from a negative angle. By the 1980s, Troyna and Carrington found that there was not overt racism, but covert racism. By this they meant that people were saying, Im not racist, but This indicates that at this time, people were aware that it was wrong to be racist, but they still had views against ethnic minorities. This shows that there may have been discrimination against ethnic minorities, but it was not intentional. They felt that schools needed to do Anti-Racist Education, this would involve more strategies to deal with overt racism and would completely remove any barriers that were apparent between the cultures. From this, it can be said there is very little or no discrimination against ethnic minorities as schemes have even been introduced to reduce the small amount of covert racism.

Doctrine of Impossibility in Contracts

Doctrine of Impossibility in Contracts Introduction This essay will consist in an attempt to analyse the doctrine of impossibility and its operation in relation to contracts. It will look closely at both the concept of initial impossibility arising from a common mistake on the part of both parties as to the state of things before the contract was agreed and the concept of subsequent impossibility and frustration. The latter deals with a situation whether the parties enter into agreement on terms both express and implied and then a supervening event renders the performance of that agreement radically different from that which was envisaged by both parties at the outset. These themes will be discussed in greater detail in the first section and will run throughout the work. The essay will examine the concept of objective and subjective impossibility, and the rules relating to discharge of contractual obligations and allocation of risk. It will look at the situation when either the subject matter or a thing essential for performance is de stroyed or unavailable, either partially or completely. It will then look at how the death or supervening incapacity of a party will affect a personal contract. Towards the latter part of the essay, it will discuss the problems that arise when a method of performance becomes impossible or a particular source becomes unavailable. It will conclude by looking at the effect of delay and temporary impossibility on a contract. The concept of impossibility The concept of impossibility in contract law can be split into two distinct categories. There are the cases where the parties never actually reach a true agreement because they are mistaken as to some element of the contract before the contract is concluded and the cases where the contract becomes impossible to perform subsequent to the agreement having been reached. Generally speaking, in the first instance, the contract is void ab initio and in the second, an otherwise valid contract is brought to an end from the point when the impossibility arises. A basic example to illustrate the difference would be a contract for the sale of a car. If unknown to the parties, the car had blown up 5 minutes before the contract was signed the contract would be void ab initio, whereas if the car blew up 5 minutes after the contract was signed, the contract would be valid, but brought to an end by the fact that its subject matter no longer existed. Essentially the courts are implying into the contra ct a condition precedent that the subject matter exists and is capable of transfer. This concept of implied condition precedent has been regarded with considerable scepticism among commentators in light of the traditional common law view that the courts should neither make nor amend a bargain. The main problem arises when dealing with the first type of impossibility. It is not always entirely clear how the courts will formulate the implied condition precedent. Smith and Thomas suggest three possibilities: A impliedly promised B that the thing existed. A impliedly promised B that he had taken reasonable care to ascertain that the thing existed. A and B proceeded on the common assumption, for which neither was more responsible than the other, that the thing existed and its existence was a condition precedent of the contract.[1] Which of these options it will be, depends largely on the relative means of knowledge of the parties and whether one is relying on the other. This will be discussed at length through the course of the work. It also may be that on proper construction of the contract either, or both of the parties have made absolute promises. In that event, the courts will not excuse non-performance for either type of impossibility. There are also cases where the contract has not become entirely physically or legally impossible, but an event has occurred which â€Å"strikes at the base of the contract so as to frustrate its purpose.†[2] This is commonly referred to as frustration and it operates as a form of subsequent impossibility. Objective and Subjective Impossibility The contract will have to be objectively impossible to perform before it is held to be void. The case of Thornborow v Whitacre (1705) 2 Ld Raym 1164 held that a party cannot escape liability on the grounds of impossibility purely relating to his individual ability or circumstances. Neither will he be discharged from his obligations simply because he finds the contract particularly difficult or onerous to perform: â€Å"It is not hardship or inconvenience or material loss itself which calls the principle of frustration into play†[3] Subsequent impossibility will similarly not excuse the parties from performance if it was brought about by the conduct of one of the parties. The case of Southern Foundries (1926) Ltd v Shirlaw [1940] AC 701 held at 717 per Lord Atkin: â€Å"†¦conduct of either promisor or promisee which can be said to amount to himself of his own motion, bringing about the impossibility of performance is in itself a breach.† Clearly, any impossibility that can be attributed to either party will be considered a breach of contract and the defaulting party will become liable in damages in the usual way. Where the impossibility brought about by one of the parties existed at the time of the contract he is likely to be held to have warranted possible performance of the contract and held to be in breach of that warranty. As discussed above it is sometimes possible for the courts to hold that a party made an absolute promise and therefore accepted the risk of the fact that the contract might be impossible to perform. Whether a contract is considered to be absolute will be a matter of objective construction of the terms of the contract. If the contract is held to be absolute, the party will be held to his performance whether or not the impossibility is his fault or not. In the case Paradine v Jane (1647) Aleyn 26 a lessee was held liable to pay rent even though he had been evicted from the property by armed forces during the civil war. A lease is a type of contract that is commonly regarded as being objectively absolute without reference to the subjective intentions of the parties. Overall the contract must be objectively impossible to perform, the subjective views of the parties as to their circumstances and their personal ability to perform the contract will not usually be taken into account. Similarly, if a party is active in bringing about the impossibility the contract will not be seen as objectively impossible, but as having been breached. Conversely, some contracts will be held to be objectively absolute and the subjective intentions of the parties in forming the contract and their level of fault in bringing about the impossibility of performance will not be relevant. Destruction of the Subject Matter In the case of Taylor v Caldwell (1863) 3 B S 826 the claimants granted the defendants the use of a music hall and gardens for a series of music concerts. After the contract had been concluded, but before the concerts had begun the music hall was destroyed by fire and the concerts could no longer be held there. The claimants argued that the defendants were in breach of the contract for failing to provide the music hall and sought to recover  £58, which they had spent on advertising the concerts. The courts however held that the contract had become impossible to perform and was therefore frustrated. Both parties were therefore released from their obligations under the contract. In coming to this conclusion Blackburn J referred to the dicta of Pothier[4] stating that: â€Å"The debtor is freed from obligation when the ting has perished, neither by his act nor his neglect and before he is in default, unless by some stipulation he has taken on himself the risk of the particular misfortune which has occurred.† He recognises that the civil law is not binding on English Courts, but states that it is a useful indicator of the principles on which the law is grounded. Blackburn J also refers to a line of authority involving bailment. For example the case of Williams v Lloyd W.Jones 179 the claimant had delivered a horse to the defendant on the condition that it be returned on request. Without fault on the part of the defendant, the horse became sick and died and was therefore not able to be returned on the request of the claimant. It was held that bailee was discharged from his promise by the fact that the horse had died. Blackburn J stated that it was a settled principle of English law that in contracts for loans of chattels or bailments, if the promise of the bailee or borrower to return the goods becomes impossible because the goods have perished through no fault of his own, the bailee is excused from this promise. It is noted that in none of the cases relating to bailment was it expressly agreed that the destruction of the subject matter would release either party from their obligation, â€Å"the excuse is by law implied† [5] This principle established in Taylor and subsequent cases[6] is now contained in section 7 of the Sale of Goods Act 1979 â€Å"Where there is an agreement to sell specific goods and subsequently the goods, without any fault on the part of the seller or buyer, perish before the risk passes to the buyer, the agreement is avoided.† Partial Destruction of the Subject Matter It is interesting to note that the contract in Taylor was for the use of ‘Surrey Music Hall and Gardens’. It was therefore only part of the subject matter that was destroyed by the fire; the gardens were still in tact. However, it was held that the destruction of the music hall rendered performance of the contract impossible. This implies that when part of the subject matter is destroyed the courts will investigate the purpose of the contract. If the part that is destroyed renders that purpose impossible the contract will be held to have been frustrated by its destruction. Discharge and Rules Governing Risk As discussed above a contract, which is the subject of a mistake made by both parties prior to its formation that makes performance impossible, will be void ab initio. This is not the case if the impossibility arises after the formation of the contract, i.e. the contract is frustrated. In that event, the contract is said to be discharged from the time when the frustrating event arose. The parties are discharged from any future performance without having to elect that that will be the case.[7] Where the core of the contract is the happening of some future event and that event is cancelled the time of frustration will be the time when the cancellation is announced. In the case of Krell v Henry [1903] 2 KB 740 the defendant hired a flat on Pall Mall to watch the coronation procession of Edward VII, though this purpose was not expressed in the contract. The procession was cancelled before the formation of the contract, but the announcement was not made until after the contract had been a greed. If the contract is severable, it may be that only part of the contract is frustrated and the other parts remain in force. It seems that even when an entire contract of sale is held to be discharged because it has become impossible to deliver some of the goods, the buyer can ‘waive’ this and demand delivery of the rest of the goods. This was the case in HR S Sainsbury Ltd v Street [1972] 3 All ER 1127. Supervening events may also make the suspend the contract without actually discharging it.[8] Temporary impossibility will be discussed in greater detail in a later section. Furthermore, illegality may frustrate a minor obligation without discharging the entire contract. The implications of things like this for a potential doctrine of partial frustration will also be discussed later. The essay will now go on to look at who should bear the risk and hence the loss of a frustrating event. For a long time it was thought that the losses resulting from the frustration of a contract should lie where they fell. This led to the conclusion that any money paid before the frustrating event occurred was irrecoverable and conversely any money already due under the contract for services provided was enforceable. In the case of Chandler v Webster [1904] 1 KB 493, CA, a room was hired to view the coronation procession, the price being payable immediately. When the procession was cancelled,  £100 had been paid on account. It was held that the contract was frustrated thereby releasing the parties from further performance, but leaving promises performable before the frustrating event still standing. On the other side a party who had only partially performed the contract could not recover anything for his services even when he had conferred a benefit on the other side.[9] It is pos sible however that a party who, after a frustrating event, takes reasonable steps to protect the other party’s interest will be entitled to recover remuneration for his expenditure on a restitutionary quantum meruit basis. This was the case in Socià ©tà © Franco-Tunisienne dArmement v Sidermar SpA [1961] 2 QB 278[10]. Until 1942 it was also considered that there could be no recovery for total failure of consideration. This was on the basis that up until the point of frustration the party who had paid any money had the benefit of a executory contractual promise and that was consideration enough[11]. However, in the case of Fibrosa Spolka Akcyjna v Fairbairn Lawson Combe Barbour Ltd [1943] AC 32 the House of Lords held that a party could recover where there had been a total failure of consideration. This was an improvement on the Chandler position discussed above, but two principle defects in the law remained. The first was that the principle only applied when there was a total failure of consideration; where there was a partial failure the claimant could not recover anything.[12] The second defect was that the payee could not set off any expenditure that he had incurred in the performance of his side of the contract. These defects were rectified by section 1(2) of the Law Reform (Frustrated Contrac ts) Act 1943. The subsection states: â€Å"All sums paid or payable to any party in pursuance of the contract before the time when the parties were so discharged (in this Act referred to as â€Å"the time of discharge†) shall, in the case of sums so paid, be recoverable from him as money received by him for the use of the party by whom the sums were paid, and, in the case of sums so payable, cease to be so payable: Provided that, if the party to whom the sums were so paid or payable incurred expenses before the time of discharge in, or for the purpose of, the performance of the contract, the court may, if it considers it just to do so having regard to all the circumstances of the case, allow him to retain or, as the case may be, recover the whole or any part of the sums so paid or payable, not being an amount in excess of the expenses so incurred.† This deals with the defects in the common law by stating that monies paid before the frustrating event are recoverable, sums payable prior to the time of discharge cease to be payable and the payee is entitled to set off expenses reasonably incurred in their performance of the contract. Goff and Jones note that whilst the Act does deal in outline with the deficiencies of the common law it does not completely resolve the issues.[13] For example, the Act does not say what principles the court ought to employ to decide how much the payee is entitled to set off. In the case Gamerco SA v ICM/Fair Warning Agency Ltd [1995] 1 WLR 1226 Garland J felt that the court’s task was to: â€Å"†¦do justice in a situation which the parties had neither contemplated nor provided for, and to mitigate the possible harshness of allowing all loss to lie where it has fallen.† Section 1(2) does permit the payee to recover or retain more than he has been paid up to the tine of frustration. I.e. for expenses incurred in expectation of future payment. They may be able to recover such expenditure under section 1(3), which takes effect when one party has conferred a valuable benefit on the other party (other than money) before the time of discharge. In that event, he will be able to recover a just sum, which shall not exceed the value of the benefit conferred. Robert Goff J held in the case of BP v Hunt [1979] 1 WLR 783 that there were two steps to assessing a claim under section 1(3), the first was identifying and valuing the benefit conferred. Goff J held that usually the benefit would be the end product of any services. In some contracts the services were the end product themselves, for example, a contract for the transportation of goods. He held that if the end product is destroyed by the frustrating event then no benefit is conferred because the other party does not have the product either. This interpretation has been heavily criticised as failing to give effect to the intention of the Act.[14] This section of the Act was intended to mitigate against the harsh consequences of the common law rule of ‘entire obligations’. In the case of Appleby and Myers (1876) LR 2 CP 651 the claimants contracted to make machinery in the defendants factory and to maintain the machinery for two years. Payment was upon completion of the wor k. After part of the machinery had been erected, a fire destroyed the whole factory and all the machinery. The claimants could not recover anything, as they had not completed the work. Goff J’s interpretation of section 1(3) would lead to the same result. However, this interpretation has also been adopted in the Commonwealth[15]. It does appear to accord closely with the wording of section 1(3), which draws a distinction between the performance by on party and the benefit conferred on the other. This implies that the claimant must actually have received the benefit of any performance on the part of the defendant before the defendant can recover or retain any money. The second step Goff J laid down was the measurement of a ‘just sum’. Contractual allocation of risk will of course be a factor. Goff J thought that it ought to be as much as is necessary to prevent the unjust enrichment of the other party. This approach was rejected by the Court of Appeal in the same case, who simply held that it was in the almost unrestricted discretion of the trial judge. In conclusion, the Act is sadly deficient in its guidance as to the allocation of risk and loss between the parties to a contract that has been discharged for frustration. It is possible for the parties to allocate the risks contractually. This is one of the main reasons that the courts have kept a tight reign on the doctrine of frustration. Parties are expected to be able to foresee the possibility of dramatic price increases and the outbreak of labour disputes etc. Contracts therefore regularly include clauses which allocate the risk of such an unforeseen event occurring. One common example is a ‘force majeure clause’. In the case of Channel Island Ferries Ltd v Sealink UK Ltd [1988] 1 Lloyd’s Rep 323 the relevant clause stated: â€Å"A party shall not be liable in the event of non-fulfilment of any obligation arising under this contract by reason of Act of God, disease, strikes, Lock-Outs, fire and any accident or incident of any nature beyond the control of the relevant party.† The advantages of such clauses are that they provide a degree of certainty and the parties can agree to a wider range of circumstances than are currently available under the doctrine of frustration. For example, an unexpected increase in prices is not considered to be a frustrating event,[16] but it is common in a commercial contract to see a force majeur clause containing provision for ‘abnormal increase in prices and wages.’ It also allows the parties to determine their future relationship. The frustration doctrine discharges the contract regardless of the wishes of the parties, but they can provide for a continuing, adapted relationship if they so wish. Unavailability of the Subject Matter Where both parties are mistaken as to the availability of the subject matter at the time of the contract, this may be sufficiently fundamental to avoid the contract. The leading case on this issue is that of Courturier v Hastie (1856) 5 HLC 637 in which the parties entered into a contract for the sale of a cargo of corn, which was believed to be in transit from Salonica to England. Unknown to both the parties, the corn’s quality had deteriorated to such an extent that the master had sold it. The House of Lords held that the matter turned on the construction of the contract concluding that: â€Å"The contract plainly imports that there was something which was to be sold at the time of the contract, and something to be purchased, no such thing existing,†¦ judgment should be given for the defendants.†[17] The exact legal basis for importing this term has been the subject of some debate among commentators and will be discussed briefly now. The draftsmen of section 6 of the Sale of Goods Act 1979 appear to have interpreted the decision as stating that a mistake as to the existence of the subject matter of the contract inevitably renders it void: 6 Goods which have perished Where there is a contract for the sale of specific goods, and the goods without the knowledge of the seller have perished at the time when the contract is made, the contract is void. The court in Couturier did not however mention the word mistake; they based their reasoning on the construction of the contract and the fact that there was a total failure of consideration on the part of the sellers. Lord Denning applied a different interpretation in the case of Solle v Butcher [1950] 1 KB 671 at 691 in which he held that there was an implied condition precedent that the contract was capable of performance. He reasoned that in Couturier the parties had proceeded on the assumption that the goods were capable of being sold, when in fact they were no longer available for sale. Lord Denning’s interpretation does seem to give effect to the most likely intention of the parties. However, in the absence of a clear intention to release each other from the agreement if the subject matter is not available, it is not clear when Lord Denning is suggesting a term of this nature should be implied into the contract. The third interpretation is that whether or not the contract will be void, depends on the its construction. This was the interpretation put on Couturier by the High Court of Australia in the case of McRae v Commonwealth Disposals Commission 84 C.L.R. 377. The defendants invited tenders for the purchase of an oil tanker described as lying on the Jourmand Reef off Papua, together with its contents, which were stated to be oil. The Claimants won the tender and spent a considerable amount of money modifying a vessel for the salvage work. In a bizarre turn of events it was later discovered that no such tanker had ever existed. The court held that: â€Å"The only proper construction of the contract is that it included a promise by the commission that there was a tanker in the position specified.† On that construction the Commission had assumed the risk of the tanker not existing. They distinguished Couturier, holding that this was not a case in which both parties had entered the contract on a common assumption. The Commission had assumed the existence of the tanker, but the buyers had only relied on their assertion. In policy terms there can be little doubt that the approach taken in McRae is a sound one and one which ought to be followed by the English courts, but its is somewhat difficult to reconcile with section 6 of the Sale of Goods Act. There is the possible argument that McRae does not fall under section 6 because the tanker had never existed and therefore could not have ‘perished’. This distinction does seem somewhat artificial and not within the intention of the court in McRae. If the subject matter becomes unavailable after the contract has been concluded this may also render the contract frustrated for impossibility. For example in the case of Bank Line Ltd v Arthur Capel Co [1919] AC 435 a charterparty was held to be frustrated when the ship was requisitioned and so unavailable to the charterer. Temporary unavailability may also suffice, but this will be discussed later. Destruction or Unavailability of a Thing Essential for Performance Lord Atkin in the case of Bell v Lever Brothers Ltd [[1932] A.C. 161, discussed the circumstances in which one might wish to imply a condition into the contract. He states that a condition derives its efficacy from the consent of the parties, express or implied. He supposes a possible term: â€Å"Unless the facts are or are not of a particular nature, or unless an event has or has not happened, the contract is not to take effect.† If there are express words in the contract such as ‘a foundation essential to the existence’, there need not be any further enquiry, but when there are no such words the court must investigate the circumstances of the agreement to see whether any such condition can be implied. Lord Atkin uses the example of the hire of a professional vocalist whose continued health would be essential to the performance of the contract. The case of Krell v Henry [1903] 2 KB 740 has been discussed earlier. For present purposes it can be described in the following terms: The contract was for the hire of a room on Pall Mall to watch the coronation procession of Edward VII. The subject matter of the contract was the room and that was still in tact. However, the purpose of the contract was to watch the procession and without the procession the contract was not capable of full performance. Vaughn Williams LJ refers in his judgment to the case of Nickoll v Ashton [1901] 2 K.B, which is authority for the proposition: â€Å" English Law applies the principle not only to cases where performance of the contract becomes impossible by the cessation of existence of the thing which is the subject matter of the contract, but also to cases where the event which renders the contract incapable of performance is the cessation or non existence of an express condition the continued existence of which is necessary for the fulfilment of the contract, and essential to its performance.† This concept was extended in Krell to include a situation in which that particular set of circumstances (the viewing of the coronation) was not expressly mentioned in the contract. The contract in Krell was, however a strange one; the room was only hired out by the day, not the night, and the purpose for the contract on both sides was the viewing of the coronation. It is clear that the particular set of circumstances must have been in the contemplation of the parties and one that they both realised was necessary for the full performance of the contract. There is some dispute surrounding the Krell case. Cheshire and Fifoot point out that the cancellation was probably not in the contemplation of the parties, but with regard to the proposition that the buyer should be discharged from his obligation to pay on cancellation: â€Å"It is incompatible with the character of a hard bargainer to say that the owner of the room would have agreed to this proposal if it had been put to him during negotiations.†[18] It is more likely that the owner would have told the hirer that that was a risk he would have to take. It seems somewhat unreasonable to import to the seller a state of mind which he may well not have been in had he thought about it. McElroy and Williams, on the other hand say that the contract was impliedly for the hire of â€Å"rooms to view the procession†, the fact that there was no procession therefore amounted to a complete failure of consideration on the part of the owner of the rooms, discharging the hirer from his obligation to pay.[19] The circumstances in which Krell will apply are extremely limited. The set of circumstances, which the parties assume to be continuing, must be the common foundation of the contract. In the case of Herne Bay Steamboat Co v Hutton [1903] 2 KB 683 the claimant hired a ship from the defendant to watch the naval review and for a day’s cruise around the fleet. After the contract, the naval review was cancelled owing to the same illness of Edward VII, but the contract was held not to have been frustrated. This is thought to be because the hirer could still see the fleet and the boat had not been hired out by the owner for the specific purpose of seeing the Naval Review. This meant that seeing the Naval Review was not the common purpose of the contract and its cancellation was not therefore a frustrating event. Thus interpreted, Krell can be seen as a very narrow decision and as indeed been distinguished in more recent cases.[20] The Death of a Person Essential to Performance In the case of Galloway v Galloway (1914) 30 TLR 531 the defendant thought that his first wife had died and married the claimant. The defendant and claimant subsequently separated and entered into a deed of separation under which the defendant agreed to pay the claimant a weekly sum in maintenance. The defendant then discovered that his firs

Studying The Peach Fruit Fly: Bactrocera zonata

Studying The Peach Fruit Fly: Bactrocera zonata Abstract The peach fruit fly, Bactrocera zonata (Saunders) is one of the most harmful species of Tephritidae. It is a polyphagous species attacking more than 40 species of fruit crops and has also been recorded from wild host plants. The peach fruit fly is a serious pest of peach, guava and mango; secondary hosts include apricot, fig and citrus. It causes serious economic losses, either by direct damage to fruits or indirectly by warranting the need for quarantine and phytosanitary measures. Bactrocera zonata is native from India and is present in numerous tropical countries of Asia. However, this pest has been established in Egypt since the late 1990s and is now largely widespread throughout the country. Therefore, it demonstrated its ability to establish outside tropical climates and its adaptability to local temperate conditions. In Egypt, B. zonata is active throughout the year when temperatures exceed 10 °C and can complete several generations per year, apparently overwintering also in temperate climates. Bactrocera zonata is well adapted to hot climates and shows higher low-temperature thresholds than those of the Mediterranean fruit fly, Ceratitis capitata, which is widespread in the Mediterranean countries. Pest risk analysis suggests that the peach fruit fly is capable to establish and spread in coastal areas of the Mediterranean region, causing significant damage on fruit production. of entering, establishing, spreading and causing significant impacts on fruit production in other countries of the Mediterranean region. INTRODUCTION Tephritid fruit flies (Diptera: Tephritidae) have a major impact on world agriculture, causing yield losses and reducing the quality and marketability of agricultural crops. Control of fruit flies mostly relies on the application of broad-spectrum insecticides, which could cause food contamination, side effects on beneficials and pest resistance to insecticides. Tephritid fruit flies are among the most invasive species of fruits and vegetables in the world. Establishment of exotic flies would cause direct and indirect economic losses due to damage to fruits and  strict quarantine regulations imposed by importing countries to avoid introductions of invasive pests. The family Tephritidae, comprises nearly 4500 species distributed over most of the world and include several species that pose a potential threat to Mediterranean horticulture, mainly of the wide-ranging genus Bactrocera, native to South East Asia and Australasia, the genus Anastrepha, originated from Central and South America, and the genus Ceratitis, indigenous to Africa. The genus Bactrocera is considered a serious threat of fruit crops because of the wide host range of its species and the invasive power of some species within the genus (White and Helson-Harris 1992; Clarke et al., 2005). Several Bactrocera species established outside of their native Asian range: Bactrocera carambolae Drew and Hancock in Surinam and northern Brazil, Bactrocera cucurbitae (Coquillet) in Hawaii, East and West Africa, Bactrocera dorsalis Hendel in Polynesia and Hawaii, Bactrocera invadens Drew, Tsuruta and White in Sub-Saharan Africa and Bactrocera zonata (Saunders) in the eastern Mediterranean basin (Vayssià ¨res et al., 2008). The two polyphagous fruit flies presently established in the Mediterranean region are the Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann), the most dangerous and widespread species, and the peach fruit fly B. zonata, which has been detected in Egypt in1998 and spread throughout the country (Amro and Abdel-Galil, 2008). The peach fruit fly was intercepted at the port of Valencia in 2005 by quarantine officials on citrus fruits imported from Egypt. Therefore, a Pest Risk Assessment (PRA) was carried out by Spain and submitted to the European Food Safety Authority (EFSA) for a scientific opinion. The PRA pointed out that the peach fruit fly can establish and spread in southern Europe, causing considerable damage to fruit yield. However, the pest risk assessment can be improved by defining the potential climatic range of the pest in Europe and identifying fruit crops potentially at risk (EFSA, 2007). Bactrocera zonata is listed as Dacus zonatus in Annex IAI of Directive 2 000/29/EC, which includes harmful organisms whose introduction in EC countries are banned. In the present paper we review the life history, host range, influence of climatic factors  and provide a tentative distribution map of the peach fruit fly in the Mediterranean region along with control methods. DISTRIBUTION The peach fruit fly is native to tropical Asia and is widely distributed in Bangladesh, Bhutan, India, Indonesia (Sumatra), southern Iran, Laos, Myanmar, Nepal, Oman, Pakistan, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates, Viet Nam, Yemen. It also occurs on the Indian Ocean islands of Mauritius and Reunion (EPPO, 2005). In Pakistan, this fruit fly is abundant in coastal and sub-coastal areas of Baluchistan and Sind, and in semi-desert areas and northern plains of Punjab. However, it has also been recorded as rare from foot hills of Islamabad and Peshawar valley of North Western Frontier Province (Hussain, 1995). In Sri Lanka, this species is distributed throughout the island in wet and dry zones and has been recorded up to the elevation of 1800 m (Tsuruta et al., 1997). In the last decades, the peach fruit fly has spread westward and has established in the Arabian Peninsula and Egypt. Bactrocera zonata was identified in 1998 on infested guavas collected in Agamy and Sabahia, near Alexandria. In 1999, monitoring traps showed high capture rates in Alexandria and Cairo. In October 2000, the pest was detected in North Sinai and is at present widespread in all the fruit-growing areas of Egypt (EPPO, 2008). California has been invaded multiple times (1989, 2001 and 2006) by the peach fruit fly, but it has been successfully eradicated (EPPO, 2005). LARVAL HOST RANGE The peach fruit fly has been recorded infesting over 40 cultivated and wild plant species, mainly those with fleshy fruits (Table 1). In Pakistan, B. zonata is a serious pest of guava, mango, peaches, papaya, persimmon and citrus. Damage of 25-50% has been reported in guava, of 10-15% in mango and of 40% in persimmon (Syed et al., 1970; Qureshi et al., 1992; Stonehouse et al., 2002). The relative susceptibility of the most common cultivated fruits in New Valley Oases (Egypt) was determined in field on the basis of adult emergence from infested fruits. Sour orange appeared to be the highest susceptible host, followed by orange and guava, whereas mandarin, apple, mango and fig were more resistant/showed some sort of resistance (Amro and Abdel-Galil, 2008). In Egypt, the highest number of pupae and the highest percentage of adult emergence were recorded under laboratory conditions from pear fruits, followed by guava, peach, apple and apricot (Shehata et al., 2008). Bactrocera zonata seems more adapted to attack citrus fruits than C. capitata. In fact, in 2002/2003 at Fayoum Governatorate (Egypt), the two species infested 15.5 and 0.35% of Navel orange, 10.0 and 0.9% of grapefruit, 8.7 and 3.7% of mandarin, 5.7 and 3.4% of sour orange, 0.6 and 0.3% of lemon and 0.6 and 0.3% of Valencia orange, respectively (Saafan et al., 2005). Restrictions by overseas markets are inevitable if research funding actions show that the peach fruit fly is established in Mediterranean countries. LIFE HISTORY The peach fruit fly is anautogenous, i.e. it emerges from puparia as sexually immature adult that needs to feed to survive and reproduce. Adults obtain sugars from honeydew  and other plant exudates, protein from bird feces and phylloplane bacteria and moisture from dew and rain. Adults are attracted by some plant-derived phenyl propanoids (e.g., methyl eugenol), that might play a role in the mating behaviour. Mated females pierce the skin of host fruits with their ovipositor and lay a batch of 2-9 eggs. The eggs usually hatch in a few days and the young larvae feed upon the fruit pulp destroying the fruit. Tunnels created by larval feeding also allow the entry of secondary pathogens causing secondary fruit rot. The mature larvae leave the fruit and pupate in the soil where they emerge two weeks later as young adults. Bactrocera zonata is a non-diapausing and multivoltine species with overlapping generations. In Pakistan and Egypt, adults are present throughout the year except in January and February (Hussain, 1995; Farag et al., 2009). Overwintering mostly occur in the larval or pupal stage. Adults a strong flier, capable of dispersing more than 24 km in search for host plants (Qureshi et al., 1975). Passive dispersal is mainly by means of winds and transportation of infested fruits. Adults live for 30-60 days and the pre-oviposition period (including sexual maturation of 8-16 days, ranges from 10 to 23 days. A female can lay up to 93 eggs/day, and as many as 564 in its lifetime (Qureshi et al., 1974). Under favourable conditions, the eggs hatch into larvae within 2 days. The larvae feed in the fruits for 4 to 30 days, depending on temperature (Duyck et al., 2004). Mature larvae burrow 2.5 to 12.5 cm in the ground to pupate. The pupal period varies from 4 days in summer to over 6 weeks in winter. Full development takes from 5 to 8 weeks, depending on the season and type of fruit infested (Shehata et al., 2008). The most important parameters influencing the population dynamics of B. zonata are the favourable environmental conditions for reproduction and survival, and host sequence, suitability and availability. Several generations per year are completed under favourable conditions. In Pakistan, the peach fruit fly complete 8-9 generations per year in the coastal plains, whereas only two generations are completed in 5 months in northern areas (Hussain, 1995). At Giza Governatorate (Egypt), seven overlapping generations were recorded from March to November; the first generation is the longest, occurring from March to May-June, whereas summer generations lasted 4-6 weeks. Populations are usually at their lowest level at the end of the winter due to the slowdown or cessation of development. It may take several generations are needed to reach the highest population density, which was observed during the 5th generation at the end of August (Farag et al., 2009). Influence CLIMATIC FACTORS AND OF HOSTS Climate plays a critical role as the determining factor of the peach fruit fly abundance, influencing development and survival, therefore limiting its geographical range. The wide distribution of B. zonata indicates a considerable degree of environmental plasticity. Although the immature stages of Bactrocera sp. can survive short periods of high (>30 °C) or low temperatures ( The temperature is the most important factor determining developmental rates of immatures and adult maturation rates. The duration of the peach fruit fly lifecycle is mainly affected by temperature and host fruit species. Development ceases in all stages below 12 °C; larvae and pupae are more resistant to cold weather conditions. The developmental thresholds of pre-imaginal stages of a peach fruit fly population in Reunion were determined at constant temperatures. Lower thresholds of eggs, larvae and pupae ranged from 12.6 to 12.8 °C, which were higher than those of C. capitata (10.2-11.6 °C). The thermal units required for the development of pre-imaginal stages were estimated in 224 degree day units (Duyck et al., 2004). However, in Egypt, the lower temperature threshold was determined as 11.84 °C and the thermal units required to complete a generation (from egg to egg) were 487 degree days (Sharaf El-Din et al., 2007). Differences on lower developmental thresholds might be due to the different strains and the larval food. However, the existence of cold-hardening ecotypes of the pest can not be ruled out. The upper temperature threshold was estimated as higher than 35 °C (Qureshi et al., 1993; Duyck et al., 2004). The optimal temperatures for development and survival of pre-imaginal stages occurs at 25-30 °C. The duration of the pre-ovipostion period ranged from 23 days at 20 °C to 8.4 days at 30 °C. Fecundity and adult longevity were optimal at 25 °C (Qureshi et al., 1993). Reliable temperature thresholds and thermal constants appropriate for each life stage allow the development of phonological models to predict the duration of the life cycle of the peach fruit fly under various climatic conditions. On the basis of thermal units, expressed as cumulative degree days, a number of 6, 7 and 8 annual generations have been predicted in North Sinai, El Beheira and Asyout (Egypt), respectively (Khalil et al., 2010). Host quality strongly affects development time and survival of pre-imaginal stages and the reproductive parameters of adults. Peach, guava and mango were the most suitable fruits for larval development and fecundity with respect to other fruit species (e.g. apple, pear, plum, orange) (Hussain, 1995). Climatic factors and host suitability influence coexistence of tephritid fruit flies in some areas. The peach fruit fly was detected in Reunion in 1991 and appears to be displacing C. capitata in warm and dry areas. Ceratitis capitata and B. zonata attack almost the same fruit species, indicating that species niche partitioning is determined by climatic factors rather than host range (Duyck et al., 2008). The peach fruit fly showed displacement ability also over B. dorsalis and Carpomyia vesuviana Costa in some areas of its native geographical range (Agarwal and Kapoor, 1986). POTENTIAL GEOGRAPHICAL DISTRIBUTION IN THE MEDITERRANEAN BASIN The potential distribution of the peach fruit fly in the Mediterranean basin has been modelled/predicted with CLIMEX. Based on climatic data, this software compares the geographical distribution of a species in the native area and predict its potential geographical range in other continents using the Compare Locations function (Sutherst et al., 2007). The model combines a weekly population growth index (in response of temperature, rainfall and relative humidity) with 4 stress indices (cold, hot, wet and dry) into an Ecoclimatic Index (EI), which indicates the potential propagation and persistence of the species as determined by climate. A database of 30-year climatic data for meteorological stations irregularly located in the Mediterranean basin was used. Climatic parameters used were modified from available data of other tephritid fruit flies (C. capitata and B. dorsalis) (Vera et al., 2002; Stephens et al., 2007), also considering the climatic requirements of B. zonata (Duyck et al., 2004). Then, values were adjusted to fit the distribution of B. zonata in Egypt. To provide a more realistic prediction of the pest range, the Irrigation option in CLIMEX was used. Figure 1 shows a tentative distribution map of B. zonata based on Ecoclimatic Index. Under current climate conditions, the model predicts the establishment and persistenc e of the peach fruit fly in coastal areas of North Africa and Near East. The suitability of European countries to B. zonata establishment was limited to southern areas of Portugal, Spain, Greece and all the main Mediterranean islands (Balearic Islands, Sardinia, Corsica, Sicily and Crete). The potential geographical distribution of the peach fruit fly appears to be narrower than that of C. capitata, which is more adapted to cool temperatures. Moreover, the predicted range of B. zonata seems to coincide with most of the Mediterranean citrus-growing areas. CONTROL METHODS Biological control of the peach fruit fly is ineffective, because young larvae feed into the fruit flesh and are protected from parasitoids. The most common hymenopterous parasitoids recovered from B. zonata in the native area are the braconid Diachasmimorpha longicaudatus (Ashmead) and the eulophid Aceratoneuromyia indica (Silvestri) (Kapoor 1993). In Egypt, Dirhinus giffardii Silvestri (Hymenoptera: Chalcididae) and the pteromalids Spalangia cameroni Perkins and Pachycrepoideus vindemiae Rondani have been recorded on peach fruit fly pupae (Badr El-Sabah and Afia, 2004). Recently, biological control efforts have been focused on augmentative release of D. longicaudatus and Fopius arisanus (Sonan) (Hymenoptera: Braconidae) (Rousse et al., 2006). Bactrocera zonata males are attracted to citronella oil and to its active compound methyl eugenol (Howlett, 1915). This parapheromone, which is present in many plants, has both olfactory and phagostimulatory action and attracts peach fruit fly males from up to 800 m (Roomi et al., 1993). Methyl eugenol proved to be very effective in early detection of peach fruit fly males and has been used in several suppression programs (Qureshi et al., 1981; Sookar et al., 2006). The male annihilation technique (MAT) employs methyl eugenol to attract most of the males of B. zonata populations. Extermination of males in a population severely reduces the frequency of fertile matings, minimizing the chances of successful reproduction and consequently lowering the infestation on fruits. Peach fruit fly males are caught/killed by plastic traps baited with methyl eugenol (mass trapping technique) or attracted to wooden blocks soaked with parapheromone and insecticide (attract and kill technique). MAT is the standard technique to eradicate the peach fruit fly from areas newly-invaded areas and has successfully been applied in several eradication programs (California, Israel) (Spaugy, 1988; EPPO, 2008). A large eradication program based on the massive use of bait stations (wooden blocks) has been very successful in Egypt: B. zonata populations have been reduced about 4-fold from 2008 to 2009 in all the countrys fruit-producing areas (FAO/IAEA, 2010). A number of insecticides used against fruit flies are effective, flexible and low toxic to non-target arthropods. In the European Union, chemicals registered against the medfly include organophosphates (chlorpyrifos-methyl and phosmet) and pyrethroids (lambda-cyhalothrin and deltamethrin). In addition, some naturally-derived insecticide are accepted in organic agriculture, such as spinosad, that is less toxic to beneficials than traditional insecticides, and a Neem formulation/azadirachtin, that showed sterilant and oviposition deterrent activities on the peach fruit fly (Mahmoud and Shoeib, 2008). All these compounds are non-systemic, therefore control treatments are targeted to kill adults and prevent egg-laying in the fruit. Bait applications integrate insecticide and attractant formulations to lure male and female adult fruit flies. The most effective control strategy worldwide against fruit flies consists in bait sprays of malathion mixed with hydrolysed protein acting as attractants and phagostimulants. However, malathion has recently been excluded from the list of plant protection products allowed in the European Union, which has also prohibited importation of fruits with malathion residues. Laboratory experiments carried out in Egypt showed that spinosad might effectively replace malathion in bait applications against the peach fruit fly (El-Aw et al., 2008). Bait insecticides are sprayed in spots on the foliage of host plants by ground or aerial applications. Studies have been carried out to control B. zonata with the sterile insect technique (SIT) (Qureshi et al., 1974), that is widely used in eradication programs against C. capitata and B. dorsalis. However, this technique has never been adopted in the field against the peach fruit fly. The establishment of the peach fruit fly in Mediterranean countries would prevent export of fruits and vegetables to countries with quarantine regulations or be made conform to their rules and restrictions. Fruit fumigation with methyl bromide is still adopted in several countries, but its use may soon be prohibited. Therefore, alternative fruit sanitation techniques based on temperature manipulation have been developed. Cold treatments consist in holding export products at constant temperatures for a time period sufficient to ensure death of the most resistant peach fruit fly life stages (eggs and larvae). Alternatively, fruits can be disinfested with high temperature treatments (water dips, dry or vapour heat, forced hair). Heat treatments can cause fruit injury and alteration of colour, aroma, flavour or texture in some citrus fruits. CONCLUSIONS The host-plant range of the peach fruit fly is broad, with more than 40 plant species verified as hosts in ; therefore, potential hosts are abundant in the diverse, cultivated and uncultivated flora of Mediterranean region and pose the eventuality of peach fruit fly population cycling. This cycling is characterized by different host-plant species sequentially serving as fruit fly reproductive hosts for parts of the year. Given the lack of diapause in this frugivorous tephritid and its wide host range, population cycling in alternate hosts could play a major role in the potential establishment of Bz and future economic depredations of exotic fruit flies such as the peach fruit fly in Mediterranean region. Peach fruit fly is a generalist tephritid species infesting many host species throughout the entire geographical range. Locally these generalists may utilize only a few of their potential host species. However, no absolute statement about plant susceptibility can be made. A good host in one geographic location may not be as good a host in another, and vice versa, as slight environmental changes may occur that influence the plants desirability as a host. In addition, it is important to analyze the plant species in a given area to identify the competing host range. A desirable host in one area may be less desirable in another because a better host exists. The population dynamics of such tephritid species are also susceptible to fluctuations in community attributes, i.e., plant diversity, interspecific interactions, and abiotic factors. These allow such tephritids to become pestiferous in some areas, but barely noticeable in other areas, or subject them to localized extinction in still other areas Rapid transport of infested host fruits through cargo, personal luggage, and mail has complicated efforts to contain peach fruit fly within its present distribution. Efforts should be made to improve exclusion, prevention, detection, and control practices against peah fruit fly, with the aim of decreasing the risk of introduction. Since eradication efforts can be extremely difficult and expensive when peach fruit fly populations become well established, such efforts are started as soon as possible after introductions are detected. Crop yield reductions, control measures, handling processes, and quarantine restrictions on commodity movement are expenses associated with peach fruit fly infestations. Appropriate phytosanitary measures should be applied to avoid the invasion and establishment of these exotic pests in the Mediterranean region. We believe that Mediterranean countries can no longer ignore the inevitability of recurrent peach fruit fly populations. The Mediterranean countries must prepare to deal with the eventuality and consequences of permanent peach fruit fly populations. Economic importance Impact of peach fruit fly on agriculture Peach fruit fly can have a direct impact on agricultural production in Mediterranean area. One estimate of the direct impact of peach fruit fly in Egypt was million euros, which did not include the costs or impacts of insecticide use to control this pest. A great number of crops in the Mediterranean countries are threatened by the introduction of this pest: including apple, apricot, peach, fig, grapefruit, nectarine, orange, peach, pear, persimmon, plum, pomegranate, tangerine. While the direct loss of production of fruit fly host products can have a significant impact on Mediterranean agriculture, perhaps a more important impact is the loss of potential production and markets due to the threat of fruit flies and the high economic costs for their control. A Streetcar Named Desire, Tennessee Williams | Analysis A Streetcar Named Desire, Tennessee Williams | Analysis A Streetcar Named Desire From time to time in life, there are periods when one is faced with conflicts and more often, it does not matter how hard one tries, you just cant fix things and you end up feeling like a broken record. A Streetcar Named Desire focuses on an inconsolable woman called Blanche Dubois. Blanche is a victim of herself and her lifestyle as much as she is the victim of an unfair state of affairs. There are occurrences in her life that she could have handled better ad therefore avoided calamity, but there are as well instances where, there was nothing she could do but play along to the tragic up folding events in her eventful life. First she is nurtured in Old South upper-class traditions, she lived in a classy manner in the family homestead Belle Reve, wedded a man she immensely loved, and followed a professional career as an English teacher. From the beginning of the play, it is forthcoming that she is the victim of her lifestyle, and not a conqueror. The individual Blanche is at present can be covered back to a solitary day in her epic past. Inside only some hours for the duration of this single day, her life would be altered completely. Blanche unexpectedly but walked in on her companion, Allan Grey, in bed having intimacy with another male. She afterwards went to a bar to have a drink with her cheating spouse and his homosexual partner; there she drunkenly told Allan that she was sickened by him. Allan flees the room in serious embarrassment from Blanches utterances and turns a revolver he had on his mouth, she hears him commit suicide in the exterior of the bar they were drinking. Any person would be unba lanced after so mucch pandemonium and distress in such a short period. Argument is fronted that since Blanche had inferred to Allan as disgusting, he committed suicide and this makes Blanche the aggressor and not the victim she almost paints herself to be. Allans deeds towards his suicide were totally his and Blanche could not manage to prevent them. It is obvious that neither of the couple could grip the confusion manifesting at the time and handled them in divergent ways. Blanche was just the fatality of the awful state of affairs that affected the love of her life. Without her dearly loved Allan, Blanche ultimately needed love. All the men Blanche would charm in seduction were because she wanted to mend the emptiness in her heart. This was however not the truthful way to manage affairs and if she had gotten help she could properly have dealt with the pain of her husbands tragic demise. Unfortunately Blanche never had that chance, when she loses her familys plantation, Belle Reve, she is forced to live in Laurel, where she engages in prostitution for the reason that she has no other way of making money to help fend for her personal upkeep. During this tumultuous period, she resides in hotel Flamingo and men seeking sexual pleasures in exchange for money come up to her room every nighttime. Promiscuous sexual relations with men got terribly out of control out of hand. Every time one sexual relation ended, a new one budded the next day. This made her to cement a lousy reputation in the small township of Laurel, Mississippi. Understanding that she was still smarting from the demise of her suicidal husband and acknowledging that the various men could not patch up her inconsolable heart, she turned to drinking to escape her misery. Haphazard alcohol drinking and one-night stands eventually makes Blanche to find herself lonely and with nowhere to go. In order to improve her miserable life and acquire a new character, Blanche makes a decision to begin afresh in Elysian Fields, New Orleans with her young sister, Stella and her bad-mannered husband Stanley Kowalski. Feigning innocence and perfection, to cover up her inadequacies back home is not sufficient as Stellas husband can see right through her. Stanley exposes her precedent behavior and devastates the fresh life she has embarked on in New Orleans she again is back where she began. Blanche is victim to Stanleys insensitive mistreatment. Not oblivious to the truth that they had not once got along, had Stanley not exposed her secrets, she might just have brilliantly started a fresh, improved life. Only to worsen her life further, she becomes the victim of serious sexual assault to the churlish Stanley. If she was not mentally and emotionally unbalanced minded before, Blanche is absolutely now. Stanley was crooked and should not have handled her the way he did, while she was obvi ously in such an unselfconfident shape. Due to her disturbing past and no prospects to seek healthy help, Blanche succumbs to mistreatment and becomes the victim to additional situations than she had to all through the routes of her life. In the closing stages of A Streetcar Named Desire, Blanche is taken to mental establishment where it is only hopeful she may get the necessary assistance to her physical, emotional and mental state. She has suffered too much and respite is necessary for her soul.

Graves Disease Essay -- Graves disease Biology Essays

Graves' Disease The disease was first noted in 1786 by Caleb Hillier Parry 1755- 1822, physician from General Hospital, Bath, England. His account was published posthumously in 1825. However Graves' disease is named after the Irish physician who described several cases in London Medical Journal in 1835. Graves' disease is also known as Parry's disease. In Europe, the disease is known as Basedow's disease. It is the most common cause of thyrotoxicosis (the morbid condition due to over activity of the thyroid gland). The disorder has three major manifestations: Hyperthyroidism with diffuse goiter Ophthalmopathy and Dermopathy The three manifestations need not appear together. Indeed one or two never appear, and moreover, the three may run courses that are largely independent of one another. Graves' disease can occur at any age but is unusual before puberty. It most commonly affects the 30 to 50 year age group. The disease is more frequent in women, the ratio of predominance in women may be as high as 7 : 1. Genetic factors play a role. There is an association between the disease and the genes HLA ( human leucocyte antigen) B8, -DRw3, -Bw36, -Bw46. Indeed, a 50% concordance is found between identical twins. This means that if one individual in an identical pair of twins is afflicted with Graves' disease, the likelihood of the other sibling coming down with Graves' is 50%. Being an autoimmune disease, there is a clinical and immunologic overlap between Graves' disease and other diseases with prominent autoimmune features. These include Hashimoto's thyroiditis, pernicious anemia, systemic lupus erythematosus ( SLE), rheumatoid arthritis ( RA), insulin- dependent diabetes mellitus ( IDDM), and Addison's disease. Thyroid hormones are important mediators of growth and differentiation. The absence of which leads to cretins in childhood. The hormones are also responsible for the regulation of the various metabolic pathways which are vital for life. They are necessary for the normal function of many organ systems. In the thyroid gland, multiple follicles make, store and release thyroid hormones into the surrounding capillaries. These little vessels then bring the hormones to the rest of the body where they are needed. "Thyroid hormones" refers mainly to two hormones T3 and T4, which are single, amino acids containing iodine. They are p... ...tient is willing to take replacement Thyroxine for life, the simplest approach may be the use of radioiodine. There are arguments for and against giving radioiodine to children and young persons who plan to have children. Previously, clinicians are unwilling to advise its use under the age of 45. This restriction is now rapidly being laxed as there is no convincing evidence that there is significant increase in the incidence of cancers occurring in adulthood secondary to its usage. Radioiodine can ensure that mothers are not taking anti- thyroid drugs during pregnancy and breastfeeding. Therefore, an argument can be made for using this treatment method for all age groups except when pregnant or breastfeeding. Relapse of Graves' disease after medical therapy may be managed with a second course, but at this point radioiodine is preferred. During pregnancy and breastfeeding periods, PTU ( propylthiouracil) appears to be the safest drug to use. And surgery is advised in cases with the presence of concomitant suspicious nodule. Each of the 3 major treatments ( anti- thyroid drugs, surgery and radioactive iodine) has their own advantages and disadvantages compared to the others.

The Conflict with Traditional Culture Essay -- Traditional Culture, Ho

The conflict with traditional culture The general people consider Hong Kong as an international city because a lot of cross-cultural enterprises choose Hong Kong as a landing base to enter into Chinese market and even Asian market.As a result ,the conscientious of women leadership can be brought into the working ecology through the expending of multinational firms. Nevertheless, it is misleading that the concept of women leadership can wholly be applied to companies in general and help increasing the number of women leader. There are several reasons. Firstly, in Asian countries including Hong Kong , the local market climate is dominated by the local companies and those companies are a kind of family business. A family business means one family has a significant ownership and influence to the decision in the company and the chairman of the company can only be the son within the family. This tradition can be a huge and unbreakable barrier to the women even though the companies are facing the influence of external culture. More important is that this new working concept especially the idea of women empowerment can not readily neutralize the traditional culture. The reason behind is that the setting rule of patriarchy is still utilized in the world today. Patriarchy is a social system which is male dominate and is central in the social organization. (Chesney-Lind, 2006) .One obvious example is that the children surname are followed by father’s family name, which means the sons are entitled to inherit everything from their father normally.

Discussion: In the lab with germinated and dry peas along with glass beads, determining the rate of respiration in each different type of seed was the goal. The hypothesis stated that since the germinated peas were still alive, they would contain a highe r rate of respiration needed to remain healthy compared to the dried peas and glass beads.Time was our independent variable and amount of 02 consumed was the dependent. The different types of beads were separated into separate respirometers where the rate of respiration was taken as time went from 5 to 10 to 15 to 20 minutes. Dye was used to measure the reading of each test subject as time went on. The data does correspond to the hypothesis due to the fact that we see an increase in 02 consumed as time goes on in germinated peas. It is assumed that dry peas would have a lower need for 02 consumed compared to germinated peas and the data represents this statement.The glass beads which are the control would not have a need for 02 consumption because they are not alive. The corrected difference (02 consumption) for the dry peas stayed at . 01 02 consumed/sec whereas as the germinated peas rose in 02 consumption as time went. They went from . 28 to . 45 to . 61 to . 665 02 consumed/min. Germinated peas had a corrected difference increasing as time went on supporting the hypothesis in the end. I would accept my hypothesis because it is assumed that germinated peas need more 02 than dry peas.This hypothesis corresponds with the data collected from the lab. The rates for the germinated peas show that the respiration rate is steadily increasing over time where as the dry peas remain almost exactly the same. In all the data supports the hypothesis that germinated seeds contain a higher rate of respiration. No errors occurred but many were avoided. A misread from the respirometers could have messed up data collection and collected differences. In addition, trying to see the reading on the respirometer could have forced some dye to seep from the tip, causing a misread.
