Avian Vacuolar Myelinopathy essays

Avian Vacuolar Myelinopathy essays In November 1994 to December 1994, twenty-three bald eagles died due to an unknown cause (Fischer 1995). In November 1996, American coots were also found dead or dieing due to this mysterious disease (Fischer 1997). Labeled Coot and Eagle Brain Lesion Syndrome, it was changed to Avian Vacuolar Myelinopathy when it was discovered to affect other species as well. It has become the most significant unknown cause of eagle mortality in the history of the United States. Avian Vacuolar Myelinopathy causes lesions in the white matter of the brain and the spinal cord of an affected bird (USACE). What causes Avian Vacuolar Myelinopathy remains a mystery even to this day. Avian Vacuolar Myelinopathy is an avian disease that is believed to be caused by a neurotoxin of unknown origin. It causes lesions in the white matter of the brain and in the spinal cord of affected birds. Dead Avian Vacuolar Myelinopathy birds appear to be in good body condition and have no visible external or internal changes with the exception of microscopic neural lesions. Electron Microscopy is used to confirm the disease, but can only be used on fresh specimens that have not been frozen. The clinical signs of a bird affected with Avian Vacuolar Myelinopathy are quite noticeable. A water bird will demonstrate a partial paralysis on one side of the body. This will result with the bird swimming with one leg extended, swimming in circles, and swimming upside down. A bird flying will demonstrate erratic flight, a reluctance to fly, or an inability to fly. On the ground, affected birds stagger and wobble. Bald Eagles affected with AVIAN VACUOLAR MYELINOPATHY have been seen flying into trees and rock ledges. Brain lesions have also been found in coots that showed no clinical signs of infection. A few sick eagles have been captured alive and sent to clinics for treatment, but they all died within 1-2 days despite medical assistance (USACE). ...

Simple Random Sampling vs. Systematic Random Sampling

Simple Random Sampling vs. Systematic Random Sampling When we form a statistical sample we always need to be careful in what we are doing. There are many different kinds of sampling techniques that can be used.  Some of these are more appropriate than others. Often what we think would be one kind of sample turns out to be another type. This can be seen when comparing two types of random samples. A simple random sample and a systematic random sample are two different types of sampling techniques. However, the difference between these types of samples is subtle and easy to overlook.  We will compare systematic random samples with simple random samples. Systematic Random vs. Simple Random To begin with, we will look at the definitions of the two types of samples that we are interested in.  Both of these types of samples are random and suppose that everyone in the population is equally likely to be a member of the sample. But, as we will see, not all random samples are the same. The difference between these types of samples has to do with the other part of the definition of a simple random sample. To be a simple random sample of size n, every group of size n must be equally likely of being formed. A systematic random sample relies on some sort of ordering to choose sample members. While the first individual may be chosen by a random method, subsequent members are chosen by means of a predetermined process. The system that we use is not considered to be random, and so some samples that would be formed as a simple random sample cannot be formed as a systematic random sample. An Example Using a Movie Theater To see why this is not the case, we will look at an example. We will pretend that there is a movie theater with 1000 seats, all of which are filled. There are 500 rows with 20 seats in each row. The population here is the entire group of 1000 people at the movie. We will compare a simple random sample of ten moviegoers with a systematic random sample of the same size. A simple random sample can be formed by using a table of random digits. After numbering the seats 000, 001, 002, through 999, we randomly choose a portion of a table of random digits. The first ten distinct three digit blocks that we read in the table are the seats of the people who will form our sample.For a systematic random sample, we can begin by choosing a seat in the theater at random (perhaps this is done by generating a single random number from 000 to 999). Following this random selection, we choose this seat’s occupant as the first member of our sample. The remaining members of the sample are from the seats that are in the nine rows directly behind the first seat (if we run out of rows since our initial seat was in the back of the theater, we start over in the front of the theater and choose seats that line up with our initial seat). For both types of samples, everyone in the theater is equally likely to be chosen. Although we obtain a set of 10 randomly chosen people in both cases, the sampling methods are different. For a simple random sample, it is possible to have a sample that contains two people who are sitting next to each other. However, by the way that we have constructed our systematic random sample, it is impossible not only to have seat neighbors in the same sample but even to have a sample containing two people from the same row. What’s the Difference? The difference between simple random samples and systematic random samples may seem to be slight, but we need to be careful. In order to correctly use many results in statistics, we need to suppose that the processes used to obtain our data were random and independent. When we use a systematic sample, even if randomness is utilized, we no longer have independence.

Persuasive - Research Paper Example By criticizing tobacco politics and highlighting financial burden, health hazards, and its prevalence, paper tries to persuade the readers about the danger of secondhand smoke and necessity of adopting effective laws and policies to protect people from secondhand smoke. On 18 June, 2002, Lynn French, a non-smoking flight attendant who worked for TWA airlines from 1977 to 1998 when smoking was still permitted in commercial flights, was awarded astonishing compensation of 5.5 million US dollars by the Miami Jury in a historic verdict against some of the leading cigarette manufacturing companies such as, Philip Morris, Reynolds Tobacco Holdings, Brown & Williamson Tobacco unit, and British American Tobacco (A WSJ News Roundup, 2002). The case against tobacco companies was filed under the accusation that Lynn French’s nonstop work in smoky, enclosed cabins of airlines caused significant negative impact on her health, including sinus problem. Lynn suffered from serious sinus infection due to the constant exposure to secondhand smoke, requiring long-term medical treatments (A WSJ News Roundup, 2002). The Lynn’s case is just another example of numerous victims of secondhand smoke all over the world, however, majority of them are not as lucky as Lynn in getting the justice. Today, the number of active smokers is rapidly increasing in the world. Consequently, at the same time, a large number of non-smoking populations, including children, has been exposed to secondhand smoke. Various researches and scientific studies have regularly highlighted serious negative effects of secondhand smoke on the physical and psychological health, yet the issue of secondhand smoking is widely neglected. The purpose of this paper is to emphasize on the severe negative effects of secondhand smoking and necessity of implementing effective measures against it. Before revealing health hazards of

Is Royal Mail justified in offering and promoting its direct mail Research Proposal

Is Royal Mail justified in offering and promoting its direct mail services - Research Proposal Example Under the Postal Services Act 2000, the UK government decided to introduce Postcomm as the regulator of a universal framework designed to protect the customers from unreasonable price increase of post stamps and poor quality postal services such as delayed, damaged or lost letters and parcels. (Postcomm, 2008; BBC News, 2004) As part of increasing the efficiency of post mail services throughout UK, the local government decided to open the post mailing business to other private operators. (BBC News, 2004) In line with the growing competition in the post mail industry, the researcher will answer the research question ‘Is Royal Mail justified in offering and promoting its direct mail services?’ by examining both the positive and negative impact of ‘junk mail’ under the British Royal Mail services. In the process of justifying the pros and cons of ‘junk mail’ services, the researcher will discuss the size of volume increase in direct mail; the commercial and social effects of increasing the ‘junk mail’ volume as well as the ecological effects of ‘junk mail’ services. There are pros and cons with regards to the delivery of ‘junk mail’ also known as the unsolicited or unaddressed commercial mails to households. To evaluate the benefits and consequences of junk mail, the researcher will discuss the following: According to the Local Government Association (LGA), roughly 78,000 tonnes of junk mail reaches the landfill sites each year. (Oliver, 2006) In 2005, as much as 4,002 million personal mails and 1,132 million commercial mails were distributed all over UK. (DMIS, 2006: 2) This figure reflects a 62% increase in Direct Mail in the last 10 years. (See Table I – Direct Mail Volume 1990 – 2005 on page ) The main social and commercial problem attached with the increasing volume of junk mail is the fact that not all households that constantly receive junk mail are reading the mails. As a major social consequence of increasing

‘There is a minimum level of care that every person with diabetes deserves and should expect from their health service’ (DiabetesUK, 2011) During her time of care, Mrs Kaur will be entitled to regular checks of her cholesterol, blood glucose and blood pressure. Also her weight, legs, feet, eyes and kidney function should be regularly monitored and help with accessing educational courses and specialist treatments that are available. Mrs Kaur should also be entitled to emotional support, advice on quitting smoking, psychological support and an individual care plan. Other services that should be made available to Mrs Kaur are free prescriptions, support in managing her condition, access to support groups and the ability to take part in diabetes events such as the ‘living with diabetes day’ event.

Hinduism and Buddhism Essay

Hinduism and Buddhism are two of the renowned religions world widely. Hinduism is the religion of the great majority of the people of India. The word comes from the Sanskrit sindhu, â€Å"river,† and originally referred to the Indus. Hinduism is actually a collection of many native Indian religions, past and present. It is responsible for the social structure of India, especially for the caste system (a hereditary class system). Hinduism has about 20 sects, with beliefs that range from primitive forms of animism to the highest reaches of mysticism and philosophy. Many of the sects and cults seem to be separate religions. Yet all have a family relationship since they spring from common traditions and thrive. Hindus believe in rebirth, or reincarnation, and in what they call the law of karma. Under this law the conditions of each new lifetime are determined by the actions of the preceding life. To the Hindu, salvation consists of liberating the soul from attachment to worldly desires in order to gain union with Brahman. If a Hindu dies liberated he must be born again into this world and again endure its suffering (Stutley, 2004). The Vedas describe four main castes. 1. The Brahmins exercise spiritual power. (Brahmin is also spelled Brahman). 2. The Kshatriyas are warriors who exercise secular power. 3. The Vaisyas are merchants and cultivators. 4. The Sudras are artisans and laborers. Hindu worship for most part takes place in the home. A Hindu temple or shrine is considered an abode of deity and is not used for communal worship. There are kinds of Hindu clergy. Temple priests collect offerings and care for the temples and shrines. Domestic priests perform rites involving births, marriages, and deaths. Gurus are spiritual teachers. Sadhus are monks; most live in monasteries, but many live as wandering mendicants (beggars) (Chaudhuri, 1999). While Buddhism is a religion founded by Siddhartha Gautama (â€Å"Buddha,† or â€Å"The Enlightened One†) in India about 500 B. C. Buddhism is the chief religion of Burma, Sri Lanka, Thailand, Japan, Korea, Mongolia, Kampuchea, Laos, and China. It has been estimated that about one-fifth of the world’s people are Buddhists. Because many Buddhists also practice Confucianism or Taoism, however, some authorities estimate world membership to be much smaller. In the United States, there are a number of organized Buddhist congregations (Carrithers, 2003). Buddhism consists of numerous sects with varying practices and beliefs. Some of these sects are so different from the others that they appear to be separate religions. But all sects have in common the belief that they are following the principles laid down by Gautama. Early Buddhism, the religion as taught by Gautama, developed into two branches—Theravada Buddhism and Mahayana Buddhism (Mizuno, 2001). Although Buddhism was originally a reform movement that rejected certain beliefs and practices of Hinduism, the two religions have several important beliefs in common. Among them are reincarnation, the ideas that a living thing can be reborn in a new body; the law of karma, which holds that events in life are effects whose cause lies in previous lives and acts; and liberation, or salvation, the state of being free of the law of karma and rebirth (Conze, 2002). According to Buddhism, liberation is attained through understanding and practice of the Four Noble Truths: 1. There is suffering in life. 2. Suffering is caused by desire for pleasure, existence, and prosperity. 3. Suffering and rebirth cease when one ceases such desires, leading to enlightenment, or Nirvana, a blessed state in which peace, harmony, and joy are attained. The Eightfold Path is also called the Middle Way—because of its emphasis on avoiding such extremes as following sensuous pleasures on the one hand, and self-punishment on the other. The Buddhists must at all times observe in the high moral principles described in the Eightfold path, which emphasizes nonviolence and the brotherhood of all. Reference: 1. Carrithers, Michael.
