Very simply for such a complex area, it is an illness of the brain. What is the difference between Alzheimer’s and dementia? The word dementia is an umbrella term, which covers all the various dementias including Alzheimer’s. Alzheimer’s is the one widely recognized, and accounts for about sixty per cent, of all the dementias. Dementia is a term that is used to describe a collection of symptoms including memory loss, problems with reasoning and communication skills, and a reduction in a person’s abilities and skills in carrying out daily activities such as washing, dressing, cooking and caring for self. Memory loss – this can be one of the first symptoms that people notice. The observations people report include – noticing their loved ones forgetting things that have happened earlier in the day, getting confused about messages and who people are, getting lost whilst out and about, repeating themselves, and appearing not to be paying attention or following conversations. Problems with communication – Some people experience problems with expressing themselves, talking and understanding things. They get confused about words and might use the wrong words for common things and mix words up. Reading and understanding written text can become problematic. There are a number of different types of dementia the most common being Alzheimer’s disease, vascular dementia, Fronto temporal dementia and Dementia with Lewy bodies. Some people get diagnosed as having mixed dementia; this is when the presentation shows the person to have elements of more than one type of dementia. Dementia is a progressive condition, which means the symptoms will gradually get worse. This progression will vary from person to person and each person will experience dementia in a different way. Although the person will have some of the above symptoms, the degree to which they affect an individual will vary and not all people will have all of these symptoms. 2. Areas of the brain affected by dementia are shown in the diagram below: [pic] The temporal lobe of the brain if affected by dementia will mean the sufferer will ‘forget’ every day functions, and how to perform them, relatives names and faces, their ‘past’ life, and friends they have known for years. Simple tasks that they used to perform with ease, become difficult to perform, and they have to ‘learn’ how to do them again. Sufferers can forget conversations and instructions, and need to be reminded on a regular basis, and given ‘prompts’ to remind them the topic of conversation, or what they are supposed be doing next for example. The frontal lobe of the brain if affected by dementia can mean that the sufferer is ‘unaware’ that their behaviour is unacceptable, or not the ‘norm’. The sufferer can become agitated very quickly, and suffer from depression. They may be unaware of apparent dangers, and unable to recognise what is ‘acceptable’ or ‘unacceptable’ behaviours. They may have violent outbursts, and exhibit ‘threatening’ behaviour to others. The parietal lobe of the brain if affected by dementia affects language skills. This means that communication skills could be reduced. The person may not be able to ‘find’ the appropriate words to use, or may not understand questions asked of them. They may not relate ‘words’ to the correct ‘objects’ for instance if they pick up a cup, but call it a ‘pot’. 3. Depression, memory problems, and delirium may be mistaken for dementia because these are often the onset symptoms of dementia, and therefore may be mistaken for the start of dementia in the elderly. Some symptoms of dementia are similar to symptoms of some mental health conditions. It is important that a comprehensive assessment is carried out if service users start to display symptoms such as confusion, poor memory or apathy. These could be indicators of dementia, but they could also be symptoms of depression, or other mental health conditions. OUTCOME 2 1. The medical model of dementia is of mental decline. This approach makes it hard to focus on maximising a person’s abilities and improving their quality of life. Putting physical problems and emotional states down to brain damage, the medical model overlooks the social world of people with dementia, and concentrates on the illness, rather than the person. 2. The social model of dementia sees the ‘person’ rather than the illness or disease. It puts the focus on what a person ‘can do’, (positives), instead of focussing on what the person can no longer do (negatives). The social model looks at ways to improve the quality of life, and experiences of dementia, and provide techniques for the dementia sufferer, to live a fulfilling and rewarding life. The social model recognises and includes the individual’s social, recreational, spiritual needs, instead of just their medical or personal care needs.

How to Use Footnotes in Research Papers

How to Use Footnotes in Research Papers A footnote is a reference, explanation, or comment1 placed below the main text on a printed page. Footnotes are identified in the text by a numeral  or a  symbol.  Ã‚   In research papers and reports, footnotes commonly acknowledge the sources of facts and quotations that appear in the text. Footnotes are the mark of a scholar, says Bryan A. Garner. Overabundant, overflowing footnotes are the mark of an insecure scholar - often one who gets lost in the byways of analysis and who wants to show off (Garners Modern American Usage, 2009). Examples and Observations Footnotes: vices. In a work containing many long footnotes, it may be difficult to fit them onto the pages they pertain to, especially in an illustrated work.Content footnotes  supplement or simplify substantive information in the text; they should not include complicated, irrelevant, or nonessential information...Copyright permission footnotes  acknowledge the source of lengthy quotations, scale and test items, and figures and tables that have been reprinted or adapted.Content FootnotesWhat, after all, is a  content footnote  but material that one is either too lazy to integrate into the text or too reverent to discard? Reading a piece of prose that constantly dissolves into extended footnotes is profoundly disheartening. Hence my rule of thumb for footnotes is exactly the same as that for  parentheses. One should regard them as symbols of failure. I hardly  need to add that in this vale of tears failure is sometimes unavoidable.Footnote FormsAll notes have the same gene ral form:1. Adrian Johns. The Nature of the Book: Print and Knowledge in the Making (Chicago: University of Chicago Press, 1998), 623.If you cite the same text again, you can shorten subsequent notes:5. Johns. Nature of the Book, 384-85. The Disadvantages of FootnotesMore than one recent critic has pointed out that footnotes interrupt a narrative. References detract from the illusion of veracity and immediacy . . . . (Noel Coward made the same point more memorably when he remarked that having to read a footnote resembles having to go downstairs to answer the door while in the midst of making love.)Belloc on Footnotes[L]et a man put his foot-notes in very small print indeed at the end of a volume, and, if necessary, let him give specimens rather than a complete list. For instance, let a man who writes history as it should be written - with all the physical details in evidence, the weather, the dress, colors, everything - write on for the pleasure of his reader and not for his critic. But let him take sections here and there, and in an appendix show the critic how it is being done. Let him keep his notes and challenge criticism. I think he will be secure. He will not be secure from the anger of those who cannot write clearly, let alone vividly, and who have never in their lives been able to resurrect the past, but he will be secure from their destructive effect. The Lighter Side of FootnotesA footnote is like running downstairs  to answer the doorbell on your wedding night. 1 The footnote has figured prominently in the fictions of such leading contemporary novelists as Nicholson Baker2, David Foster Wallace3, and Dave Eggers. These writers have largely revived the digressive function of the footnote.(L. Douglas and A. George, Sense and Nonsensibility: Lampoons of Learning and Literature. Simon and Schuster, 2004) 2 [T]he great scholarly or anecdotal footnotes of Lecky, Gibbon, or Boswell, written by the author of the book himself to supplement, or even correct over several later editions, what he says in the primary text, are reassurances that the pursuit of truth doesnt have clear outer boundaries: it doesnt end with the book; restatement and self-disagreement and the enveloping sea of referenced authorities all continue. Footnotes are the finer-suckered surfaces that allow tentacular paragraphs to hold fast to the wider reality of the library.(Nicholson Baker, The Mezzanine. Weidenfeld and Nicholson, 1988) 3 One of the odd pleasures in reading the work of the late David Foster Wallace is the opportunity to escape from the main text to explore epic footnotes, always rendered at the bottoms of pages in thickets of tiny type.(Roy Peter Clark, The Glamour of Grammar. Little, Brown, 2010) Sources Hilaire Belloc,  On, 1923Chicago Manual of Style, University of Chicago Press, 2003Anthony Grafton,  The Footnote: A Curious History.

Cybercrime - Essay Example or illustrates also that the capital flight and financial frauds have increased substantially during the period from 1965 to 2010, from 49 billion to 1,043 billion USD, respectively. However, it is becoming more difficult to estimate the development of the amount of financial means of transnational crime over time (Schneider 2013, 700). Further the author describes the most common methods of money laundering and identifies twenty destination countries that have the largest amount of laundered money among which the leaders are the United States, the Cayman Islands and the Russian Federation. Schneider analyzes the progress of money laundering activities in relation to the proceeds of cybercrime. Schneider (2013, 692) provides estimates of the various cost components of genuine cybercrime, among which are given estimates for online banking fraud (including: phishing, malware (consumers), malware (businesses), bank tech. countermeasures), as well as fake antivirus, copyright-infringing software, copyright-infringing music, patent-infringing pharma, stranded traveler scam, fake escrow scam, and advance-fee fraud. According to the estimates during the period 2007-2010, the total costs of genuine cybercrime made up $3,457million (Schneider 2013). In addition to the estimates of genuine cybercrime, the author provides estimates of costs incurred by transitional cybercrime, which includes the following: online payment card fraud; offline payment card fraud; indirect costs of payment fraud; loss of confidence (both consumers and merchants) (Schneider 2013). The total costs of transitional cybercrime made up $44,200million. Moreover, there are even provided the costs of cybercriminal infrastructure, which include: expenditure on antivirus, ISP cleanup expenditures, cost to industry of patching; cost to users of cleanup; defense costs of firms; and expenditure on law enforcement (Schneider 2013). The total costs of cybercriminal infrastructure made up $24,840 million. And

Business cultural - Dissertation Example 115). Strengthened by the maximum gross domestic product (GDP) per capita within North African region and government expenditures going beyond 48 billion USD every year, Libya has rapidly turn out to be one of the most lucrative markets in the region for a wide range of products and services. As foreign businesses assess the prospect of entering this potentially productive market, endurance, a dependable associate and profound understanding of the political as well as business setting are significant assets that should come with any future venture. Background As Libya carries on to recover from the Qadhafi era, businesses will certainly come across a number of the similar challenges many Libyans have coped with for years. From a functioning point of view, these aspects repeatedly disrupt the best of project management attempts and exponentially raise the level of endurance essential to function successfully (Bayoud et al, 2012, p. 145). Nonetheless, in a culture focused on associatio ns, the value of a dependable associate with the necessary understanding of the Libyan market cannot be devalued. Looking for an associate with the cultural understanding and continuing political as well as business dealings required to get things done can usually indicate the difference among achievement and collapse. While this business setting will certainly modify during the coming months as the lately nominated General National Congress (GNC) carries on to deal with its parliamentary priorities, companies must be responsive towards existing regulatory requirements. Businesses should as well be aware of a decision linked with â€Å"new customs tariffs issued by the GNC’s predecessor, the National Transitional Council† (Joffe, 2011, p. 240). The general charge of customs duties shall be five percent, with the exception of some particular products that charged higher duty rates starting from 10 percent up to 30 percent. There are some offered within this decision how ever, up till now, a thorough customs tariff chart has not yet been published. While many may consider the inherent challenges of the existing Libyan market as daunting, there are still some companies from around the globe who are recognizing the bright prospects at hand once the problems are being taken care of. Following a year of inconsistency and 42 years of dictatorship, Libyans are dedicated towards helping the country to apprehend its potential and identify the part for foreign business during the process (Adetunji, 2011, p. 209). With the proper leadership, global businesses can do well in Libya and deliver products and services that the financial system requires as it goes to the next level. For companies who can afford to be enduring, who can operate with a dependable local associate and stay at the forefront of political and business

Genetic Engineering of BT Cotton

Genetic Engineering of BT Cotton INTRODUCTION BT cotton Cotton and other monocultured crops require an intensive use of pesticides as various types of pests attack these crops causing extensive damage. Over the past 40 years, many pests have developed resistance to pesticides. cSo far, the only successful approach to engineering crops for insect tolerance has been the addition of Bt toxin, a family of toxins originally derived from soil bacteria. The Bt toxin contained by the Bt crops is no different from other chemical pesticides, but causes much less damage to the environment. These toxins are effective against a variety of economically important crop pests but pose no hazard to non-target organisms like mammals and fish. Three Bt crops are now commercially available: corn, cotton, and potato. As of now, cotton is the most popular of the Bt crops: it was planted on about 1.8 million acres (728437 ha) in 1996 and 1997. The Bt gene was isolated and transferred from a bacterium bacillus thurigiensis to American cotton. The American cotton was subsequently crossed with Indian cotton to introduce the gene into native varieties. The Bt cotton variety contains a foreign gene obtained from bacillus thuringiensis. This bacterial gene, introduced genetically into the cotton seeds, protects the plants from bollworm (A. lepidoptora), a major pest of cotton. The worm feeding on the leaves of a BT cotton plant becomes lethargic and sleepy, thereby causing less damage to the plant Cotton is a soft, staple fiber that grows around the seeds of the cotton plant, a shrub native to tropical and subtropical regions around the world, including the Americas, India and Africa. The fiber most often is spun into yarn or thread and used to make a soft, breathable textile, which is the most widely used natural-fiber cloth in clothing today. It is a natural fibre. The English name, which began to be used circa 1400, derives from the Arabic meaning cotton. In the 19th and early 20th centuries, In the Southern United States, cotton was known as King Cotton because of the great economic and cultural influence it had there. Cotton has been spun, woven, and dyed since prehistoric times. It clothed the people of ancient India, Egypt, and China. Hundreds of years before the Christian era cotton textiles were woven in India with matchless skill, and their use spread to the Mediterranean countries. In the 1st cent. Arab traders brought fine muslin and calico to Italy and Spain. The Moors introduced the cultivation of cotton into Spain in the 9th cent. Fustians and dimities were woven there and in the 14th cent. in Venice and Milan, at first with a linen warp. Little cotton cloth was imported to England before the 15th cent., although small amounts were obtained chiefly for candlewicks. By the 17th cent. the East India Company was bringing rare fabrics from India. Native Americans skillfully spun and wove cotton into fine garments and dyed tapestries. Cotton fabrics found in Peruvian tombs are said to belong to a pre-Inca culture. In color and texture the ancient Peruvian and Mexican textiles resemble those f ound in Egyptian tombs. Field trials have n that farmers who grew the Bt variety obtained 25%-75% more cotton than those who grew the normal variety. Also, Bt cotton requires only two sprays of chemical pesticide against eight sprays for normal variety. According to the director general of the Indian Council of Agricultural Research, India uses about half of its pesticides on cotton to fight the bollworm menace. Organic cotton Organic cotton is cotton that is grown without insecticide or pesticide. Worldwide, cotton is a pesticide-intensive crop, using approximately 25% of the worlds insecticides and 10% of the worlds pesticides.Organic agriculture uses methods that are ecological, economical, and socially sustainable and denies the use of agrochemicals and artificial fertilizers. Instead, organic agriculture uses crop rotation, the growing of different crops than cotton in alternative years. The use of insecticides is prohibited; organic agriculture uses natural enemies to suppress harmful insects. The production of organic cotton is more expensive than the production of conventional cotton. Although toxic pollution from synthetic chemicals is eliminated, other pollution-like problems may remain, particularly run-off. Organic cotton is produced in organic agricultural systems that produce food and fiber according to clearly established standards. Organic agriculture prohibits the use of toxic and persiste nt chemical pesticides and fertilizers, as well as genetically modified organisms. It seeks to build biologically diverse agricultural systems, replenish and maintain soil fertility, and promote a healthy environment. Bacillus thuringiensis Bacillus thuringiensis is a Gram-positive, soil-dwelling bacterium of the genus Bacillus. Additionally, B. thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies, as well as on the dark surface of plants.[1] B. thuringiensis was discovered 1901 in Japan by Ishiwata and 1911 in Germany by Ernst Berliner, who discovered a disease called Schlaffsucht in flour moth caterpillars. B. thuringiensis is closely related to B. cereus, a soil bacterium, and B. anthracis, the cause of anthrax: the three organisms differ mainly in their plasmids. Like other members of the genus, all three are aerobes capable of producing endospores.[1] Upon sporulation, B. thuringiensis forms crystals of proteinaceous insecticidal ÃŽÂ ´-endotoxins (Cry toxins) which are encoded by cry genes.[2] Cry toxins have specific activities against species of the orders Lepidoptera (Moths and Butterflies), Diptera (Flies and Mosquitoes) and Coleoptera (Beetles). Thus, B. thuringiensis serves as an important reservoir of Cry toxins and cry genes for production of biological insecticides and insect-resistant genetically modified crops. When insects ingest toxin crystals the alkaline pH of their digestive tract causes the toxin to become activated. It becomes inserted into the insects gut cell membranes forming a pore resulting in swelling, cell lysis and eventually killing the insect. Genetically modified cotton Genetically modified (GM) cotton was developed to reduce the heavy reliance on pesticides. The bacterium Bacillus thuringiensis naturally produces a chemical harmful only to a small fraction of insects, most notably the larvae of moths and butterflies, beetles, and flies, and harmless to other forms of life. The gene coding for BT toxin has been inserted into cotton, causing cotton to produce this natural insecticide in its tissues. In many regions the main pests in commercial cotton are lepidopteran larvae, which are killed by the BT protein in the transgenic cotton that they eat. This eliminates the need to use large amounts of broad-spectrum insecticides to kill lepidopteran pests (some of which have developed pyrethroid resistance). This spares natural insect predators in the farm ecology and further contributes to non-insecticide pest management. BT cotton is ineffective against many cotton pests, however, such as plant bugs, stink bugs, aphids, etc.; depending on circumstances it may still be desirable to use insecticides against these. Genetically modified cotton is widely used throughout the world. However, researchers have recently published the first documented case of in-field pest resistance to GM cotton. The International Service for the Acquisition of Agri-biotech Applications (ISAAA) said that, worldwide, GM cotton was planted on an area of 67,000 km ² in 2002. This is 20% of the worldwide total area planted in cotton. The U.S. cotton crop was 73% GM in 2003. Cotton has gossypol, a toxin that makes it inedible. However, scientists have silenced the gene that produces the toxin, making it a potential food crop. Uses Spores and crystalline insecticidal proteins produced by B. thuringiensis are used as specific insecticides under trade names such as Dipel and Thuricide. Because of their specificity, these pesticides are regarded as environmentally friendly, with little or no effect on humans, wildlife, pollinators, and most other beneficial insects. The Belgian company Plant Genetic Systems was the first company (in 1985) to develop genetically engineered (tobacco) plants with insect tolerance by expressing cry genes from B. thuringiensis. B. thurigiensis-based insecticides are often applied as liquid sprays on crop plants, where the insecticide must be ingested to be effective. It is thought that the solubilized toxins form pores in the midgut epithelium of susceptible larvae. Recent research has suggested that the midgut bacteria of susceptible larvae are required for B. thuringiensis insecticidal activity. Genetic engineering for pest control Bt crops (in corn and cotton) were planted on 281,500 km ² in 2006 (165,600 km ² of Bt corn and 115900 km ² of Bt cotton). This was equivalent to 11.1% and 33.6% respectively of global plantings of corn and cotton in 2006.] Claims of major benefits to farmers, including poor farmers in developing countries, have been made by advocates of the technology, and have been challenged by opponents. The task of isolating impacts of the technology is complicated by the prevalence of biased observers, and by the rarity of controlled comparisons (such as identical seeds, differing only in the presence or absence of the Bt trait, being grown in identical situations). The main Bt crop being grown by small farmers in developing countries is cotton, and a recent exhaustive review of findings on Bt cotton by respected and unbiased agricultural economists concluded that the overall balance sheet, though promising, is mixed. Economic returns are highly variable over years, farm type, and geograp hical location Advantages There are several advantages in expressing Bt toxins in transgenic Bt crops: The level of toxin expression can be very high thus delivering sufficient dosage to the pest. The toxin expression is contained within the plant system and hence only those insects that feed on the crop perish. The toxin expression can be modulated by using tissue-specific promoters, and replaces the use of synthetic pesticides in the environment. The latter observation has been well documented world-wide Possible problems The most celebrated problem ever associated with Bt crops was the claim that pollen from Bt maize could kill the monarch butterfly. This report was puzzling because the pollen from most maize hybrids contains much lower levels of Bt than the rest of the plant and led to multiple follow-up studies. In the end, it appears that the initial study was flawed; based on the way the pollen was collected, they collected and fed non-toxic pollen that was mixed with anther walls that did contain Bt toxin. The weight of the evidence is that BT crops do not pose a risk to the monarch butterfly. There was also a report in Nature, that Bt maize was contaminating maize in its center of origin. Nature later concluded that the evidence available is not sufficient to justify the publication of the original paper. A subsequent large-scale study failed to find any evidence of contamination in Oaxaca.
