Write a about those questions - Essay Example Except for the congenital syphilis, syphilis occurs in four distinct stages. In the initial primary stage, there is formation of a sore which is a small, round and firm referred as chancre that occurs at the site of infection. Chancre usually occurs 21-90 days after infection. The ulcer usually disappears and secondary syphilis sets in. This is evidenced by skin rash which do not itch at soles and palms. Symptoms associated with secondary stage syphilis include headache, swollen lymph glands, sore throat and tiredness. In the latent syphilis no symptoms are evident and the disease progresses to the tertiary stage. Failure to treat syphilis may lead to the complicated tertiary stage which affects almost all organs of the body including the brain, nervous system and heart. Late syphilis presents with mental illness and neurological failures. The diagnosis of syphilis maybe by examination of a chancre by a health worker and laboratory tests confirmation for the disease. Antibiotics especially penicillin are used in treatment of syphilis especially at the primary stages. Syphilis that has affected the neural system may be treated by intravenous injection of penicillin. Prevention of the disease is by avoiding contact (sexual contact) with infected individual and avoiding sex partners. Protected sex may also minimize chances of infection (National Institute of Allergy and Infectious Diseases 1). The bacterium Nesseria gonorrhoeae infects the potential victim through the genital tract, mouth and rectum. Transmission of this bacterial disease is through sexual intercourse with an infected partner oral, anal or vaginal. The bacterium has its reservoir in infected humans. Symptoms of this STD include discharge in both men and women though some infected individuals may not present with any symptoms. These symptoms are evident after 2-10 days after sexual intercourse with an infected individual. In women possible symptoms

Financial Planning - Essay Example There may be some additional cost attached with the purchasing of house is that cost of furniture fixture, electricity cost, maintenance cost and cost of decorating the house. The use of credit card incurs some cost as interest rate. As the interest rate in the credit card is very high like interest rate on the credit card of Shawn is 18% and Mary is 15%. The use of other means of payment like cash payment reduces such costs involved. Thus, they need to reduce the usage of credit cards in borrowing goods and services because the high rate of interest leads to increase in their expenses in the income expenditure statement. For this reason, if they reduce the usage of credit cards then they will be able to save the amount of interest. Shawn wants to sell off his truck any buy something new. From the primary consideration of buying vehicles, it can be said that buying new vehicles is always good though it costs high but the quality of the vehicle is brand new and Shawn can easily repair or maintain the car from the company service center if it’s new. However, if he wants to buy a used vehicle then the cost will be low as after one-year usage of any vehicle, its cost decreases. However, here he needs to consider two things- one is that the age of the vehicle. He should not purchase too old vehicle, which is having low cost because it might not be in a good condition. Second is that only age of the vehicle cannot be the measurement factor for the condition of the vehicle depends on the Km. it has run and depending on the miles or Km it can be decided that whether the vehicle is in good condition or not. Some other consideration in the purchase of a used truck is the property transfer cost and the service it w ould incur to make the used truck running and in a good condition. If the costs involved are much larger or near to the cost of a new truck, he would purchase the new one. Nevertheless, buying an old truck

The Relationship Between Alexander and the Great General Hephaestion Essay Example for Free

The Relationship Between Alexander and the Great General Hephaestion Essay Alexander III of Macedon, or better known as Alexander the Great was king of Macedon, a state in northern Ancient Greece. He was born in Pella in 356 B. C. and was tutored by Aristotle until the age of 16. By the age of 30, he had created one of the largest empires of the ancient world, stretching from the Ionian Sea to the Himalayas. He was undefeated in battle and is considered one of history’s most successful commanders. Alexander was an outgoing charismatic man, who had many friends, but his dearest and closest friend and confidant was Hephaestion. Hephaestion, son of Amyntor, was a Macedonian nobleman and a general in the army of Alexander the Great. He was born in Macedonia in 356 B. C. He was a member of Alexander the Great’s personal bodyguard, which then he went on to command the Companion cavalry, and was entrusted with many other tasks through Alexander’s ten-year campaign in Asia. Apart from being a soldier, engineer and diplomat, he corresponded with the philosophers Aristotle and Xenocrates, and supported Alexander in his attempts to integrate Greeks and Persians. Their relationship lasted through Alexander’s becoming of king, through the hardships of campaigning and the flatteries of court life, and their marriages. In all that Alexander undertook, Hephaestion was at his side making their friendship a working partnership. They worked well together making Alexander trust him and rely on him. When Alexander had to divide his forces he trusted Hephaestion with half of his men knowing that in him he had a man of unquestionable loyalty, who understood and sympathised with his aims, and above all, who got the job done. Hephaestion played a full part in Alexander’s regular consultations with senior officers, but he was also the one whom Alexander would talk to in private, sharing his thoughts, hopes and plans. Curtius states that Hephaestion was the sharer of all his secrets. At Alexander’s first wedding Hephaestion was the torch bearer (best man). This showed not only their friendship but also Hephaestion’s support for Alexander’s policies, as Alexander’s choice of an Asian bride had not been a popular one. When they returned to Persia Hephaestion was officially titled Alexander’s second in command. Hammond sums up their public relationship well: â€Å"It is not surprising that Alexander was as closely attached to Hephaestion as Achilles was to Patroclus†, and â€Å"At the time of his death Hephaestion held the highest single command, that of the Companion Cavalry; and had been repeatedly second in command to Alexander in the hierarchy of the Asian court, holding the title of Chiliarch, which had been held by Nabarzans under Darius. Thus Alexander honoured Hephaestion both as the closest of his friends and the most distinguished of his Field Marshals. It has been said that as well as being close friends Alexander and Hephaestion were also lovers. It cannot be proved that they were lovers as none of the ancient sources states this in so many words. However, Arrian describes the occasion when Alexander and Hephaestion publicly identified themselves with Achilles and Patroclus, who were acknowledged, by Plato and Aeschylus among others, to have been lovers. It happened at t he begging of the campaign in Asia when Alexander led a contingent of the army to visit Troy. He laid a wreath on the tomb of Achilles, and Hephaestion laid a wreath on the tomb of Patroclus, and they ran a race, naked, to honour their dead heroes. Robin Lane Fox, writing in 1973, says: â€Å"It was a remarkable tribute, uniquely paid, and it is also Hephaestion’s first mention in Alexander’s career. Already the two were intimate, Patroclus and Achilles even to those around them; the comparison would remain to the end of their days and is proof of their life as lovers, for by Alexander’s time, Achilles and Patroclus were agreed to have enjoyed the relationship which Homer had never directly mentioned. Nothing shows better the nature and length of their relationship than Alexander’s overwhelming grief at Hephaestion’s death. As Andrew Chugg says, â€Å"†¦ it is surely incredible that Alexander’s reaction to Hephaestion’s death could indicate anything other than the closest relationship imaginable. † Arrian says that Alexander â€Å"†¦ flung himself on the body of his friend and lay there nearly all day long in tears, and refused to be parted from him until he was dragged away by force of his companions. Arrian also said that Alexander, after Hephaestion’s death, described him as â€Å"†¦ the friend I valued as my own life. † In conclusion Alexander and Hephaestion’s relationship was extremely close. They may or may not have been lovers but the friendship they shared was one of a kind. Their tutor, Aristotle, described such a friendship as â€Å"†¦ one soul abiding in two bodies†. Paul Cartledge describes their closeness when he says: â€Å"Alexander seems actually to have referred to Hephaestion as his alter ego. † They truly were soul mates and had one of the strongest relationships in history.

The Positive Behavioural Support Education Essay

The Positive Behavioural Support Education Essay The last twenty has seen the emergence from Applied Behavioural Analysis of Positive Behavioural Support.ABS was Established in the 1960s as a science which produces behavioural changes from its learning principles. They are then systematically applied in order to bring about behavioural changes which are socially important (Cooper. Heron Heward,1987).In the late 1980s and early 1990s PBS was being developed using methods and concepts in a generalised concept of strategy of support and intervention from ABA. This strategy was intended to reduce behavioural problems and enhance a persons quality of life ( E.Carr et al.,2002).PBS owes a lot of its methodological, conceptual and technological roots from ABA, and so is indebted to ABA for this and this is well understood (E.Carr et al ., 2002).A lot of behavioural analysiss who are conspicuous contributors in ABS initially trained in ABA and they still maintain very close links with ABA.PBS is still in terms of data required and the for mation of new theoretical frameworks as it tries to establish it self as a fully distinct science in its infancy. Although due to the unique and substance of PBSs critical features it warrants a separate identity (E.Carr et al.,2002;Dunlap,2004).The links are vital and numerous between ABA and PBS ( Risley,2003).At an individual level is the debt that PBS owes to ABA at its most oblivious especially in the direct intervention practices at procedural level. With the use of the principles of instrumental methods , the use of stimulus control and positive reinforcement. And even extends to intervention technology and the considerable assessments that were developed by the ABA, in the early years. This technology includes contingency management, antecedent manipulations, refined strategies of instruction, Functional assessment and functional analysis.PBS have also adapted times series designs and methods of direct observations which are used extensively in ABA. While PBS embraces perspe ctives and traditions beyond ABAs, its service delivery is indisputably similar (J.Carr Sidener,2002;Dunlap,2004;Wacker Berg,2002).In 1968 the Journal of Applied Behavioural Analysis was founded. With its founding editor Montrose Wolf 1968-1970, and Todd Risley as editor 1972-1974,these two editors were responsible for the innovative and dynamic characteristics that were in that journal. And were in turn with their colleges were largely responsible for the shaping ABA as a discipline. Through their own research publications and the early years at the Journal of Behavioural Analysis, Risley and Wolf led the way in the development of the model of action oriented field research (Fixsen Dunlap,2004).This model is based on experimental methods and rigorous measurements, a great deal of this models uniqueness is associated with these seven appealing characteristics. 1.To solve serious human problems with a complete focus on practical solutions. 2.Messages from research should be direct and simple, Quest for Parsimony. 3.Solutions identified in research should benefit individuals in life altering ways, or large portions of society in a quest for meaningful impact. 4.Obliging research design to conform to situations and to putting solutions before the strictures of the science. 5.Recognise that in anolog contexts solutions are not real solutions in real human problems, ecological validity. 6.Having a commitment to collaborate with the community, colleges research participants and students in understanding that solutions and ideas are communal and a social phenomena. 7.Ideas are more important than any ideology. With this model of applied research the message is clearly that its important to be completely open to hopefully useful perspectives, and to be restrained by disciplinary and conceptual insularity is counterproductive. Wolf and Risley with the use of these seven characteristics in applied science, enabled them to answer critical problems.Strenghthen the vigour and potency of interventions, by the development of the achievement place group home model. And with the idea of social validation. Wolf with his colleges changed the previous restrictions of hard direct observation data (Wolf,1978).The achievement place group members with the use of systematic consumer imput to supplement the usual evidence .Where then able to refine the residential service model, and also able to replicate their findings successfully many times due to its robustness (Fixsen,Blasà ©,Timbers Wolf,2001).Without the use of social validation data this scaling up would not have been possible. Risley although a founding member of ABA showed the same ability to move beyond his disciplines limitations in his quest for answers to critical questions. Risley with Betty Hart (Hart Risley,1995) used unconventional descriptive statisti cs and data collection techniques to produce very important findings, associated with the development of young childrens language. Risley also conceived of behavioural support happenings at a larger life arrangements level. With interventions being formulated on whom and where a person on a daily bases interact with. And what they do in terms of play, work and social commerce (Risley,1996).The scientific precepts of ABA did not foresee the conceptualisation, but it shows the spirit and dynamic model of action oriented problem solving of Wolf, Risley and others created in the 1960s and 1970s.The cornerstone of PBS is the life arrangements approach by Risley. The experimental analysis of behaviour and the scientific techniques of behaviour by the early founders of ABA provided a valuable service (Sidman,1960;Skinner,1953) in the field of real human problems. Some of the founders of ABA created a dynamic and creative model of problem solving field based research, by going beyond the th is act of tranlation.whilst at the same time maintaining the many benefits and scientific orientation that were produced by early ABA. By creating additional strategies or adopting some, to defeat barriers in their way that were diminishing their effectiveness or understanding. Risley and Wolf are oblivious examples although there are and were others. The techniques and methods of ABA are essiential.But the pioneers that used the dynamic problem solving approach in ABA has also been adopted by people in PBS and should be maintained by them in order to help find new solutions that affect human well being. There is mounting concern over the challenging behaviours displayed by the numbers of young children in early childhood settings (Squires Bricker,2007).Behaviours such as tantrums,biting,yelling,hitting,withdrawal or noncompliance. Which are major barriers to effective social networks and their development of social compliance (Campbell,Specker,Burchinal,Poe The NICH, Early Child Care Research Network; Dunlap et al.,2006;Wood,Cowan Baker,2006).A childs typical development consists of these challenging behaviours in the early years, for instance a two year old child will yell when refused a biscuit or sweet. A three year old child will take a toy and then hit the other child. But these behaviours should then diminish as the child develops emotional and social regulation, language and their skills at cognitive problems increase (Campbell,1995;Tremblay et al.,2004).Approximately 10% of children continue in their preschool years to exhibit these challenging behaviours (Kuperschmidt,Br yant Willoughby,2000).This figure rises if the children are from low income families (Qi Kaiser,2003).For children who exhibit severe and/or sustained challenging behaviours the outcome is bleak. Challenging behaviours long term negative outcomes may not be limited to and can include social rejection, drug abuse, academic failure and the commission of crime in adulthood (Patterson, Reid Dishow,1992). The development pathway that leads to anti social behaviours and social conduct disorders has been shown by research to be established in the preschool years (Webster-straton,2000).Young children who are at risk of displaying patterns of challenging behaviour in preschool have a need for early intervention. In America there is such a federally funded programme called P.L. 99-457 which came about in 1986.This is an early childhood special education service or intervention. In where a child is at risk or has disabilities. But this service are not always provided for all of the chidren, who display emotional and/or social behavioural problems. Due to idiosyncrasies with the lack of assessment methods and/or systematic screening (Conway Brown,2004;Powell,Fixsen,Dunlap,Smith Fox,2007).These services when they are provided have been reactive rather proactive (Conway brown,2004).Interventions have been based on a response to a single childs disruptive behaviour. Without taking steps to reduce the likelihood of other children in the classroom developing challenging behaviour patterns. Whilst this is important for remedying severe problem behaviour in one child, it does little to reduce similar patterns of behaviour in other children. as it doesnt address their needs.Families,researchers and preschool teachers are looking for the implementation of a research based comprehensive intervention programmes. To prevent the emergence of problem behaviours by young children (Gillam Shaber,2006;Joseph Strain,2003). Preschool teachers however continue to voice the opinion tha t a childs challenging behaviour is their biggest concern (Alkon,Rambler MacLennan,2003;Joseph Strain,2003) In a recent report (Gilliam Shaber,2003) demonstrated that teachers do not have the support for early interventions that they need. The figure that rates for expulsion in preschool children are 3.2 times higher than for school age children shows this (Gilliam Shaber,2006).Child expulsion rates dropped though when preschool teachers had access to mental health consultants who are based in the classroom. These rates dropped specifically if this support was available on an ongoing bases. Other research has also supported these results, that it is important to have access to mental health specialists and the support they offer to preschool teachers. As the teachers try to manage social emotional development and challenging behaviours of young children 9Alkon et al.,2003;Duda,Dunlap,Fox,lentini Clarke,2004). A Consultant will work with a teacher in consultation for preschool children, in order to strengthen teaching strategies. With the use of environmental arrangements that are associated with childrens emotional functioning and social skills (Dougherty,2000).In a comprehensive multi systems level approach, the consultant may also work with other service related personnel and administrators. In a system level approach such as in procedures and policies for example, teachers schedules, data management and referral practices. This can help support the assessment, identification and the prevention of and intervention for challenging behaviours.Teachers,young children and early childhood service delivery arrangements can benefit from a fully comprehensive system wide model. That involves consultation in order to prevent challenging behaviour by young children, through preventative support. Positive Behaviour Support (PBS) is one such multi comprehensive approach which is team based. That sh ows promise and has been well tested especially in preschool settings (Conroy Brown,2004;Fox,Dunlap Powell,2002).PBS is a multi system wide model used in the reduction of challenging behaviours. The PBS model consists of three levels of prevention and intervention, within a programme setting or a school setting, depending of the needs of the children (Carr et al.,2002).At the first level of prevention all the children are provided with a predictive and safe environment. The focus being on trying to build relationships which are positive (Fox,Dunlap,Hemmeter,Joseph strain,2003).The physical design of the classroom also gets attention, the schedule which is followed regulary.Then there is also verbal interactions with the families, children and other teachers (Fox,et al.,2003).Along with this the children are shown clearly defined expectations. Such as the use of listening ears, safe hands and the use of quiet voices inside. These techniques are taught specifically in a large group instruction class, such as circle time (Stormont et al.,2005).These are often displayed on posters placed in the classroom walls for the children and others to look at and refer too. Then these may become classroom rules, normally there would be three to five classroom rules with accompanying posters or pictures. Which is the recommended amount, then normally every day the children are especially taught these expectations with nonexamples and examples of rule following behaviours (Stormont et al .,2005).At the second level of support which involves targeted interventions of a small group of children, who have displayed some deficits in challenging behaviours and/or social skills (Howken Horner,2003).In a classroom of young children, the programme consists of small group activities such as buddy or peer group programmes. Or strategies that are implemented by the teacher, that are used throughout the day. For instance by offering support by the teacher to the child when they are usi ng self regulation strategies (Fox et al.,2003). And in the low risk group, for children who display low intensity behaviours. Second level strategies operate in the most efficient way with small groups of children. It is at the tertiary or top level of intervention, where children are not responding to preventive attempts. Or who display severe and/or chronic challenging behaviours is individualised interventions offered. These individualised interventions should be culturally and socially appropriate, practical and come form Functional Behaviour Assessments FBA (Lewis Sugai,1999,Sugai et al.,2000).Another key feature of PBS can include the use and formation of leadership teams. Who should use in order to monitor progress data based procedures (Albin,Lucyshyn,Horner Flannery,1996).This team should consist of assistant and lead classroom teachers,families,mental health specialists, related service personnel and administrators. All of whom should work frequently with preschool teac hers to support childrens emotional and social development. The procedures used to collect data must look at the organizational structure, that is the routines and schedules that they use (Fox Little,2001;Stormont et al.,2005).PBS is a model that has a continuum of supports such as the first, second and then tertiary or top levels of prevention and intervention. Research seems to show that it needs at least 80% implementation to be effective (Scott Martinek,2006).What this means in effect is piecemeal or partial implementation may put the whole programme at risk. And its effectiveness to make targeted change and then to maintain this change over time. In conclusion looking at the research PBS can offer real help and support for the children displaying this challenging behaviour. Their teachers and importantly the families as they try to cope with this, in what can be a very disruptive and hard to deal with problem behaviour. But like every thing in this current climate, its trying to find the necessary resources for programme. which is going to be a major set back for any school that wants to implement this programme. Especially as the programme needs at least an 80% implementation rate to be fully effective.

Food Irradiation Essay -- essays research papers

Food Irradiation: Solution to Hunger or Killer Mutagen? People all over the world are starving for fresh, uncontaminated food. Insects, pests, and invisible microorganisms are not what the public want to find on their dinner plates. Throughout history, life has depended on ways of treating food to reduce or destroy these naturally occurring harmful contaminants and to enable foods to be stored after harvesting so that they can be saved for use at other times of the year. With increasing populations and the growth of cities, it is even more important to be able to preserve food so that it can be transported over considerable distances and stored for long periods before it reaches the consumer. The relentless pressure to supply safe foods to mass markets has led to major contamination problems arising in recent years. The food industry has responded by developing new methods to treat food, such as food irradiation. To some in the food industry, irradiation is a wonderful new technology that could solve many contamination problems without any apparent effects on the treated food. To the consumer, it is a new process that has unknown threats and benefits. Currently, 37 countries, including the United States, permit the use of irradiation and approximately 25 actually use it. Irradiation will remain an expensive and little used technology until there is general acceptance of irradiated foods by consumers. The modern food industry has to make certain choices as to how and when it treats food during the food production cycle. It can start by reducing the level of microorganisms and pests in food by using chemical treatments and pesticides during growth. For this to be effective the food must then be protected against fresh contamination during transport and storage. An alternative approach is to do very little to the food as grown and harvested, but to treat it nearer to the point of consumption. This is common with herbs and spices. The food industry will tend to choose the way it deals with contamination based on the economics of each case, in other words, the cheapest way possible. Even where food is produced relatively close to the point of consumption, it may have to be treated because contamination is inherent in the production process. This is why milk has to be pasteurized. Pasteurization is the most effective way of killing microorganisms with m... ...where the greed of people like Gustavus Swift turned meat-packing plants into death traps and sold ground cardboard, rats, and fingers to the public as ‘fresh meat’ while sweeping the floors of the plant to recover the sliced-off bits and package them as potted meat. Clearly the food industry is driven by capitalism, and not by concern for the consumer, and although I am wholeheartedly in favor of capitalist businesses, I do think federal regulation needs to come into play not just in the United states, but in other countries where most of the people have no legal recourse at all if they fall ill or die as the result of unclean food. Education of the consumer is the key to this problem, as is objective research. Governments around the world should be made to adhere to guidelines recommended by people whose main concern is the safe and healthy production of food, instead of the cheapest way to produce it, or what would be best for the businesses already irradiating fo od, as is the case for the federal government. Without measures taken during all aspect of food production to ensure cleanliness, the consumer is doomed to a lifetime of choices between dirty food, and dirtier food.
