A Rhetorical Analysis of The First Kiss by John Updike Essay Example

A Rhetorical Analysis of The First Kiss by John Updike Paper In the essay titled The First Kiss, author John Update portrays baseball as a love-hate relationship with its fans. Update effetely conveys his message by appealing to pathos using metaphors, personification, and rhetorical questions. He begins with a metaphor stating, The many-headed monster called the Fenny Faithful yesterday resumed its romance with 25 youngish men in red socks who last year broke its monstrous big heart. He describes the fans of baseball as a many-headed monster implying that they are aggressive from the passion that they feel for that sport. He goes on by saying that they resumed their romance with the ones who broke they heart. That suggests that even though the team had many losses last season, they will still be devoted to them at the beginning of next season. He then begins to express how the love turns to hate by stating, braced for the first kiss of another prolonged entanglement, then asks a rhetorical question, in. ho can forget the ups and downs of last years fling? he refers to the first hit of the baseball season as the first kiss, and the first kiss is always he sweetest. Next he uses personifications expressing that baseball did the cruelest tease. Hes referring to their great win streak against their number one enemy, the Yankees, but ends up losing to them because of a cheap home run. Update displays how fed up the team was by exclaiming, Enough. Youll never get us to care again, Red Sox. He puts emphasis on the word enough by making it a one word sentence. He does this to show how sick and tired the fan s and they are at their last straw. Update then returns back to the love between the fans and baseball by eating, But monster have short memories, elastic hearts, and very foldable faculties. Once again he refers the fans as monsters because he defines monsters of having short memories and elastic hearts; they quickly forget about all the bad that has happened in the past and will continue to adore them. Therefore, by using metaphors, personifications, and rhetorical questions about the ups and downs of relationships, Update effectively conveys the message that theres a love-hate relationship between baseball and its fans.

How Many Zeros in a GoogolA Googolplex

How Many Zeros in a GoogolA Googolplex SAT / ACT Prep Online Guides and Tips What’s a googol, and does it have any relation to that similarly-named website? And what about a googolplex, how many zeros does it have? In this guide, we’ll give you googolplex and googol definitions, show how you can write them out, explain how they’re useful, and give examples on how you can start to understand huge numbers like these. What Is a Googol? That’s not a misspelling! The search website Google did get their name from this very large number. A googol, officially known as ten-duotrigintillion or ten thousand sexdecillion, is a 1 with one hundred zeros after it. Written out, a googol looks like this: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. The scientific notation for a googol is 1 x10100. Even though we see a million and a billion as large numbers, there are 1 x1094 †millions† or 1 x1091â€Å"billions† in a googol, which shows you how much larger a googol is than these numbers. â€Å"Googol† got its name in 1938, when nine-year-old Milton Sirotta came up with the name and suggested it to his uncle, mathematician Edward Kasner. When the founders of Google were looking for a name for their website (back then called â€Å"BackRub†) that would demonstrate the vast amount of information it could provide, they chose â€Å"googol† but accidentally misspelled it, and a star was born. A googol is such a large number that our minds can’t even comprehend it, and because it’s so large it doesn’t have a particularly important role in mathematics. It’s even estimated that there are only 4 x 1079atoms in the universe, which is less than a googol. This means there isn’t a googol of anything on earth, not grains of sand, not drops of water in the oceans, etc. They don’t even come close to a googol which can help us get some grasp of how incredibly huge this number is. Therefore, the only times a googol is a somewhat accurate estimate of anything is for hypotheticals. A common example is that it’s estimated that there are 1 x10123 ways a game of chess could be played, which is fairly close to a googol. This is a very rough estimate, but it’s easy to see how the number could become so large. After each chess player makes their first move, there are 400 potential board setups. After each player has made two moves, there are 197,742 setups, after three moves there are over 100 million, and the number continues to increase exponentially from there. What Is a Googolplex? If a googol isn’t big enough for you, there are even bigger numbers out there! One of them is a googolplex, which is a 1 followed by a googol of zeros. The scientific notation for a googolplex is 1 x 1010^100 As massive as a googol is, a googolplex is many, many times larger, such that it’s impossible to write all the zeros out. There’d be ten-duotrigintillion of them! Counting to a googolplex would be even more impossible. We can’t calculate how long it would take, but it’s estimated it would take longer than the age of the universe. As a comparison, counting to a trillion would take roughly 31,709 years, and a trillion is only a 1 followed by twelve zeros! Edward Kasner and his colleague James Newman wrote this about a googolplex in their 1940 book Mathematics and the Imagination: â€Å"You will get some idea of the size of this very large but finite number from the fact that there would not be enough room to write it, if you went to the farthest star, touring all the nebulae and putting down zeros every inch of the way." Wow! So what’s the point of such a large number? Kasner discussed googol and googolplex to show the difference between incredibly large numbers and infinity. Kasner believed people overused the term â€Å"infinite† when they really only meant a large number, so he developed googol and googolplex to differentiate between the two concepts. Other Large Numbers You Should Know Guess what? There are even larger numbers than a googolplex, although not many. If you want to learn about all the large numbers and see a chart that makes it easy to compare them to each other, check out our guide to large numbers. One of the numbers larger than a googolplex is Skewes’ number. Skewes’ number, developed by mathematician Stanley Skewes, is 10 to the 10th to the 10th to the 34th, or this: . Skewes was especially interested in prime numbers, and when his number was introduced in 1933, it was described as the largest number in mathematics. However, Skewes’ number is no longer considered the largest possible number; that title now goes to Graham’s number. Graham’s number, which can’t be written with conventional notation, was developed by mathematician R.L. Graham. It’s so large that, even if all the matter in the universe was converted to pens and ink, it still wouldn’t be enough to write out the number in its entirety. Summary: How Many Zeros in a Googolplex? What is a googol? A googol is a 1 followed by 100 zeros. The number was first introduced by mathematician Edward Kasner, who got the name for the number from his young nephew (and which Google later used for their own name). Kasner also coined the term googolplex. And how many zeros in a googolplex? A googolplex is a 1 followed by a googol of zeros. It’s impossible to write out, but in scientific notation it looks like 1 x 1010^100. These two numbers are too large to have any practical value (they are far, far larger than the number of grains of sand or drops of water on earth, or even the number of atoms in the universe), but Kasner used them to discuss the difference between extraordinarily large numbers and the concept of infinity.

Benjamin Franklin Essay Example | Topics and Well Written Essays - 1000 words

Benjamin Franklin - Essay Example Franklin as a discoverer, he is well known for discovering the lightning rod, bifocals, and the Franklin stove. Franklin also assisted in many civic associations such as the Philadelphia’s fire department and a university. Franklin faced many challenges that he managed to overcome to achieve his goals. For instance, one of the most complicated challenges he experienced was when he appeared before the House of Commons that took place on 13 February 1766 (Isaacson, 2004). The House asked him one hundred and seventy four questions regarding taxation without representation in a limit of only two hours. There were also more series of problems that he faced; his father took him out of school when he was still young so that he could do a job and earn some money, which he was never pleased with that decision because he really liked going to school (Clark, 2004). He also faced another irritating challenge when he was at the age of 17 years for being overweight. He was extremely well-built and skinny because he spent most of his time swimming and trying to be more sporty during the last days of his life, and trying to coach other people on the basics of swimming even when he was seventy years old. Franklin was also mocked, dishonored and was ousted from his position as the postmaster general, and was held responsible by the British government for the Boston Tea Party (Clark, 2004). He was also not so good in academic work and he did not do well in academics more so in mathematics that he was scoring very low grades. Benjamin Franklin helped in major contributions and accomplishments in the history of the Unite States. For example, he was one of the founding Fathers of the U.S., assisted in the drafting of both the declaration of independence and constitution of the U.S., which was the most significant achievement of his life (McCormick, 2008). He came from a poor background and through his efforts and hard works; he became one of the great figures in the American

Email and Internet use and Privacy Policies Essay

Email and Internet use and Privacy Policies - Essay Example Moreover, the use of internet in working hours is allowed to complete business tasks. However, the use of internet brings the likelihood of contravenes to the safety of secret Company details. Moreover, internet use also causes contagion to our business structure with several spyware, malwares, Trojan horses and viruses. At my job, Email is utilized for performing business activities. However, the private information of the company should not be given away from the Company, without the approval from the company management. Additionally, it is not ethical to perform private dealings using Company PC or electronic mail (Boze & Stevens, 2010; Heathfield, 2011). Employees should keep in mind that the company keeps the record of several communications done using electronic mail or else whatever is shared on company PC. In this scenario, network administration and authorized employees have the full right to view any content in employee’s electronic mail or on employee’s PC wh enever they want. Thus, people should not think that their electronic link, storage or access to be confidential if it is managed or stored at work. Furthermore, in the place of work current developments have altered the ways workers make use of the internet and electronic mail. Thus, the businesses are confining their workers’ use of Internet and email with privacy policies (Boze & Stevens, 2010; Heathfield, 2011). What are the current laws regulating employee e-mail and Internet privacy? A lot of businesses are using the pre-established rules those confine internet and electronic mail usage for workers. In this scenario, these businesses apply privacy rules that bound the extent of privacy workers are allowed to even as in the office. Additionally, the managers are answerable for the acts of their workers or staff. Thus, most of the businesses believe that privacy of the company should have priority over worker’s privacy at the place of work. In this scenario, busine sses apply rules and laws on the internet and e-mail usage in order to defend the company beside robbery, permissible concerns, and maintain the reliability and reputation of the business (OPPapers, 2010; eNotes.com, Inc., 2011; FindLaw, 2011). In this scenario, existing laws those are regulating workers’ internet and e-mail privacy vary from country to country. However, the prime initiative of these laws describe that boss or manager who holds the e-mail framework, internet setup or networks is perfect inside their privileges to check the access to internet or e-mail in addition to practice by the staff. In this scenario, the electronic mails are managed through the Electronic Communications Privacy Act (ECPA) and the Patriot Act.  So over internet the ECPA secures together digital communications as well as electronic mail. Furthermore, the law prohibits their stoppage and detection by 3rd party. In this regard, ECPA outlined a number of distinct crimes: (OPPapers, 2010; e Notes.com, Inc., 2011; FindLaw, 2011) Accessing and trying to interrupt transmission Open connection to the transmission without approval Stopping the transmission for the reason of hindering illegal analysis Capturing communication for business operations Making use of electronic, automatic, or else extra equipment to cut off transmission What assumptions might employees make about their privacy at work? How do these policies affect employee privacy at work? The biggest concern for the majority owners or managers is legal responsibility.

Comparative ecology of urban and rural foxes

Comparative ecology of urban and rural foxes Abstract The red fox (Vulpus vulpus) is an adaptable animal that can be found anywhere with adequate food and shelter, it is therefore not surprising that they have adapted from a rural to an urban setting. Few studies have directly compared urban and rural fox ecology. This review had two primary objectives; (1) To describe habitat utilization by urban and rural foxes and (2) to discuss the variation in their diet, population dynamics, causes of mortality, social organization and behaviour by linking these variations to differences in their habitat. Many similarities were observed between the urban and rural fox. It was concluded that the features which determine the distribution and abundance of foxes may differ depending on their habitat. The diets of urban and rural foxes are proposed to be distinguished by differences in degree rather than differences in kind. In urban areas where dense populations of foxes live in close proximity there must also be greater social involvement than in the less associated rural fox communities. Population density is important when considering the spread of epizootic diseases and the timing and degree of population dispersal. 1. Introduction Over the past century increases in human population density have escalated the process of urbanisation (Mc Kinney, 2002). Organisms are now confronted with a range of novel conditions because of the modifications of the natural environment in which they ordinarily thrive. This can potentially impact both their life cycle and patterns of behaviour (Dickman and Doncaster, 1987). In recent years the effect of urbanization on the red fox (Vulpes vulpes) has been of particular interest. The concept that ecological interactions of animals may differ according to the type of habitat they occupy is not new. Differences will arise depending on the nature of the animals habitat interactions and their life history. For example, the gray squirrel (Sciurus carolinensis) and the racoon (Procyon lotor) are strongly influenced by urban variables such as proximity to houses, artificial feeders, or other physical structures (Flyger, 1970; Harris 1986). The foxs successful adjustment from a rural to an urban environment is not surprising as they are opportunistic animals that are distributed across a wide diversity of habitats. In Russia and Europe they can be found in the arctic tundra, and have been reported on sea ice 100km north of the nearest land (Harris, 1986). Foxes are to be found southwards in most European habitats. They live from western Asia to eastern Japan and southwards into the deserts of North African. Throughout most of the mainland habitats in North America the same species of fox is found (Hutchins at al, 2003). The wide distribution of the red fox, the diversity of habitats in which it can be found and the speed with which foxes have colonised areas such as Australia are all indications of its adaptability (Harris and Yalden, 2008). This review has two primary objectives: 1. To describe habitat utilization by urban and rural foxes. 2. To discuss the variation in their diet, population dynamics, causes of mortality, social organization and behaviour by linking these variations to differences in their habitat. 2. Habitat Utilization. In both urban and rural environments foxes are most abundant in diverse habitats that offer a wide variety of food and cover (Goldyn, 2003; Harris and Rayner, 1986; Mac Donald Sillero, 2004). They exercise choice in selecting a place to live within the restrictions imposed by their social behaviour (Lloyd, 1980). There are two proposed reasons for the success of the red fox across its wide distribution: 1. Size The fox is small enough to be unobtrusive, yet large enough to be able to move long distances when necessary. Therefore, it can easily colonise new areas and search areas where recourses are scattered (Harris, 1986). 2. Lack of specialization The red fox can thrive in a variety of locations as it has no particular habitat requirements (Lloyd, 1980). 2.1. Rural Habitat. The general perception of a rural habitat suitable for fox habitation is a diverse landscape consisting of scrub and woodland (Llyod, 1980). However, rural habitats also include mountains (above the treeline), moorlands, costal dunes and agricultural habitats such as arable and pastoral farmlands. Foxes have shown a marked preference for small coniferous woodlands in upland areas that are free of anthropogenic influence and afford good shelter (Goldyn, 2003). Large coniferous plantations are generally poor foraging areas for the fox; however, while ground vegetation remains they are also good habitats (Harris and Yalden, 2008). The main factor influencing the location of rural foxes is the availably and distribution of food shelter is generally not a limiting resource (Goldyn, 2003). Dens have a crucial meaning for foxes, not only as breeding places, but also as a shelter for adults during the whole year (Meia and Weber, 1993). The rural fox digs dens in a wide variety of habitats including; banks; enlarged old rabbit burrows; disused or occupied badger setts; also natural holes in rock crevices and drains (Harris 1977a; Harris 1986). Vegetative cover and water need to be within or close to denning sites for this species. They should also be located near areas with a good prey base as females seldom range more than half a mile from their dens (Hoover and Wills, 1987). In farmland areas foxes have shown a preference for denning sites that are undisturbed by humans. Wood edges and woodlots are virtually exclusive habitats where fox dens are situated (Lariviere, 1966). In farmlands adjacent to wooded areas only a minority of foxes will locate in an open habitat such as arable land. Goszozynskis study (1985) showed that in an area with 21% forest coverage; only 2% of all dens were located in open habitats. However Goldyn (2003) found that in farmlands where wood cover is lacking, foxes can successfully adapt to completely different conditions, reaching high den sites. The banks of drainage ditches, marsh banks and boundary strips between fields were also frequently used as den locations. This is indicative of the adaptable nature of the fox in a sub-optimal habitat. 2.2. Urban habitats. For the purpose of this review an urban habitat will refer to any habitat within a built up area that does not occur naturally outside it. Urban habitats include gardens, parks, wastelands, road verges, railway tracks and cemeteries (www.wildberks.co.uk). Urban habitats have become ecosystems in which mammal populations have adapted their lifestyle in order to survive. These fragmented ecosystems provide breeding sites, food and shelter for foxes (Macdonald and Newdick, 1982). In the past there has been some confusion as to which habits are important for the urban fox. It was noted by Llyod (1968) that urban foxes may live in gardens, but usually they shelter in daytime in woodlands, parks, cemeteries, and overgrown sites such as isolated building plots. Later Harris (1977a) noted that the daytime rests of most importance are quiet gardens (irrespective of size) and similar domestic habitats, he proposed that parks and public open spaces were of little importance; this is evident in Table 1. Habitat variables appear to have consistent effects on the distribution of foxes. Similar to foxes found in rural areas, the urban fox is most commonly found in areas of diverse habitat. In an urban environment diverse habitats include areas where industry, commerce or council rented housing predominate (Harris and Rayner, 1986). In London the availability of suitable habitats for daytime harbourage is an important limiting factor for the distribution of and numbers in fox populations (Harris, 1977a). Habitat Number of Specimens Percent of specimens Percent of surburban land use Resedential habitats gardens, garden sheds, cellars, houses 226 59.79 40.19 Industrial habitats sewage stations, factories, builders yards, nurseries 28 7.41 3.72 Vacant land, normally without public access 32 8.47 6.01 Parks and public open spaces 33 8.73 10.53 Hospitals 9 2.38 1.10 Allotments 20 5.29 1.29 Cemetries 10 2.65 0.74 British rail and underground lines 9 2.38 2.29 Golf courses 5 1.32 No data Sports grounds and school fields 3 0.79 2.29 Rubbish tips 2 0.53 0.59 Airports 1 0.26 1.58 Road deaths 22 Other habitats 29.67 Totals (excluding road deaths) 378 100.00 100.00 Table 1: Harris (1977a) collected and recorded the location of 400 urban fox corpses in London. This data illustrated the relative importance of the various urban habitats as daytime harbourage. It has also been suggested by several authors that railway lines may be a particularly important habitat for the urban fox. Radio-tracking in Edinburgh revealed that the types of habitats visited by foxes largely reflected their availability. Railway lines were particularly important to dog foxes as pathways between parts of their range (Treweila and Harris, 1990). In London regular disturbance is the main factor governing the distribution of dens. The majority of natal dens are situated in undisturbed habitats including under garden sheds, quiet gardens and railway embankments. Few litters are raised in dens in areas of public access; this is illustrated in Table 2 (Harris, 1977a). Rural foxes have also shown a preference for denning sites that are undisturbed by humans (Goldyn, 2003). Situation Number of Specimens Percent Under garden sheds with raised floors 36 37.1 Under concrete floors of garages, out-buildings, and raised floors of summer-houses and portable huts 10 10.3 In air-raid shelters 1 1.0 In drains 1 1.0 In banks of earth e.g. at bottom of gardens, railway embankments, etc, 29 29.9 In flat ground 9 9.3 In flower-beds, rockeries 6 6.2 In compost heaps, piles of rubbish, woodpiles 5 5.2 Total 97 100.0 Table 2: Sitting of suburban fox dens used for rearing cubs (Harris, 1977a). 3. Diet As the fox is both a predator and a scavenger, it is presented with a huge variety of prospective foods (Lloyd, 1980). Their diet depends on both location and time of year (Harris, 1986). Foxes are known to switch their diet to feed on whatever is abundant locally. They have adapted particularly well to humans by foraging in towns and hunting in areas cleared for agriculture (Hutchins at al, 2003). It is important to remember that in rural and urban areas a similar range of food types are likely to be eaten; however, the proportions will vary. For example urban foxes in London and Oxford have a broadly similar diet; Harris (1981) found that scavenged items comprised 37% of the diet of foxes in London, compared to 35% in Oxford (Doncaster et al, 1990). Foxes in Oxford ate more earthworms (27% as opposed to 12%) and fewer birds and insects (Harris, 1981; Doncaster et al, 1990). 3.1. Seasonal Variation in Diet Throughout the year vertebrates play an important role in the foxs diet across most of their range (Baker et al, 2006; Harris 1986). The proportion of different mammals in their diet will generally vary according to their location and season. For example in agricultural areas sheep (Ovis aries) are mostly eaten in winter and spring; this roughly corresponds to the lambing season which extends from January to May (Fairley, 1984). In Britain the most important mammal eaten in urban areas is the field vole (Microtus agrestis), which is more abundant in their diet during the winter months (Harris, 1986). Fruits and berries are also of seasonal importance to the fox. In the early autumn foxes include blackberries, raspberries, bilberries, cherries and hawthorn berries in their diet. They eat strawberries in great quantities during the summer months (Llyod, 1980). Lever (1959) also identified earthworms, slugs and snails as constituting a small proportion of the foxs diet in the summer months. On domestic lawns there is a more regular supply of scavenged foods and a greater availability (though not necessarily abundance) of earthworms than on rougher rural pastures (Llyod, 1980). As a result, seasonal differences in the diet of the rural fox are much more pronounced than in the urban fox, as there can be major variation at different times of the year (Harris 1986). 3.2. Scavenging In most habitats scavenging is important for the fox. In upland regions of West Scotland, where other food sources were scarce, the fox was found to scavenge in an agricultural environment. Foxes fed largely on sheep carrion and field voles (65% of mass ingested), supplemented by deer carrion, rabbits and birds (Hewson, 1984). In Ireland rural foxes were also found to scavenge on sheep afterbirths (Fairley, 1984). Scavenging is particularly important to the urban fox as it supplements its diet with a high proportion and variety of scavenged food (Doncaster et al, 1990). In the centre of cities foxes eat more scavenged food and fewer domestic pets, earthworms and wild animals than foxes found closer to the suburban fringe. (Harris, 1986) In London and Oxford scavenged food or food deliberately provided by householders accounts for over 35% of their diet (Harris, 1981; Doncaster at al, 1990). Foxes are known to raid dustbins for scraps (www.thefoxwebsite.org) and may also occasionally raid bird tables (Harris, 1986). 3.3. The fox as a predator Medium sized animals play an important role in the diet of the rural fox throughout all seasons; rabbits for example may account for up to 74% of their diet (Baker et al, 2006). In Ireland foxes tend to switch to brown rats (Rattus norvegicus) when rabbit populations are reduced by myxamatosis (Fairley, 1984). The intake of small rodents is much lower in Ireland than in Britain. It is therefore possible that rats, hares and rabbits are of greater importance to the rural Irish fox because of the restricted variety of mammalian prey, (Fairley, 1970) in particular the absence of field voles in Ireland (Lever, 1959). In agricultural environments the red fox is known to be one of the most important predators (Lloyd, 1980). A study by Conova and Rosa (1994) on the diet of foxes on agricultural land in northwest Italy found that birds and small mammals made up more than 60% of their diet. Game birds such as mallards (Anas plutyrhynchos) and pheasants (Phasianus colchicus) as well as domestic birds were preyed upon. In Brittan game birds (mainly pheasants), small mammals (predominately field voles) and large mammals comprise 11, 7 and 6% of their diet, respectively (Baker et al, 2006). In England and Ireland lambs are more susceptible to losses than poultry, this is due to the fact that they are numerous and widely dispersed and often suffer from poor husbandry and exposure to severe climatic conditions (Llyod, 1980). In the urban matrix the predatory role of fox has not been abandoned, despite the fact that lambs and wild rabbits are largely absent from their diet due to lack of availability. Instead, urban foxes prey on birds and small mammals to a greater degree than those in rural areas (Doncaster et al, 1990). Foxes are attracted to locations which have a diverse and abundant food base, whether these sources are situated in the urban ecosystem or the surrounding countryside (Dickman and Doncaster, 1987). This is emphasised by similarities in the diets of urban and rural foxes (Doncaster et al, 1990; MacDonald, 1981). The diets of urban and rural foxes are distinguished more by differences in degree than by differences in kind as some populations of rural foxes may also scavenge food from villages and farms (Doncaster et al, 1990). 4. Population Dynamics 4.1 Density Fox population density is influenced by factors such as prey availability and anthropogenic culling (Webbon et al, 2004) and varies depending on location (table 3) (Harris and Yalden, 2008). Webbon et al (2004) found that in rural hill areas, densities may be as low as 0.21 fox per km2 and peak at 2.23 foxes per km2 on arable land. High densities were positively related with areas of coniferous woodland, lowland marsh and grassland leys. In urban areas fox population density is usually higher than in similarly sized rural areas. The highest density of foxes ever recorded was 37.0 adults/km2 in North West Bristol (Baker et al, 2000). This figure was recorded immediately before an outbreak of mange. Fox Population Densities Rural (Webbon et al, 2004) Urban Habitat Number of foxes per km2 Habitat Number of Foxes per km2 Arable land 0.79 2.23 Bristol before mange outbreak (Baker et al, 2000) 37.0 Pastural land 1.39 1.88 Bristol 2.5 years after mange outbreak (Baker et al, 2000) 7.0 Marginal Upland 0.82 London (Page, 1981) 12.0 Upland 0.21 Cheltenham (Harris and Smith, 1987a) 8.96 11.2 Table 3: Population densities across urban and rural locations. 4.2. Dispersal The most important factor affecting dispersal is population density. Trewhella et al (1988) found that in areas of low fox density (rural areas) animals disperse farther than those from areas of high and medium fox density (urban areas). In very low fox density parts of Europe exceptional movements will exceed 100km: however, in Britain movements over 40 km are rare, even in hill areas where fox numbers are low (Harris and Yalden, 2008) Not only do urban foxes move shorter distances, but fewer of them actually leave the home. Trewhella et al (1988) found that by the end of their second year the final proportion of urban foxes that dispersed were 75.8% for males and 37.8% for females. The rest permanently stay on the home range where they were born. Storm et al. (1976) gathered data on rural foxes and found the proportion of foxes dispersing was somewhat higher than in Trewhellas urban study, amounting to 96% for males and 58% for females. Dispersal starts earlier in the countryside than in urban areas. Disturbance, especially by fox hunting, may be particularly important in splitting up a higher number of fox families and accelerating the dispersal of juveniles (Harris, 1986). Dispersal begins in early autumn and is largely completed by the end of the year (Storm et al., 1976). In urban areas cubs that do disperse tend to do so quite late in the season (December). This may be because most urban fox families are subject to less severe disturbance (Harris, 1986). 5. Causes of Mortality 5.1. Human induced mortalities In both urban and rural populations humans are responsible for a high proportion of fox deaths (Table 3). In urban areas road traffic is the main cause of fox mortalities (Baker et al, 2004; Harris and Smith 1987b). In 2004, 58% of fox deaths in Bristol were road deaths; the majority being killed on major category roads (e.g. motorways) (Baker et al, 2004). In rural areas the majority of deaths are caused by culling and hunting foxes. In all regions of mainland Britain there has been a steady increase in the mean number of foxes killed by gamekeepers per km2 since 1960 (Tapper 1992), with four times as many killed per km2 in 1990 as in 1960. In rural Dorset 58% of foxes were deliberately killed by hunting and culling (Reynolds and Tapper, 1995). In a survey of three rural regions in England foxes were culled in 70 95% of farms (Reynolds and Tapper, 1996). Hunting with dogs took a number of forms before the introduction of the Hunting Act in 2004. 21,000 25,000 foxes were killed annually by approximately 200 registered packs of foxhounds; with terriers digging out 55,000 dens and lurchers killing 10,000 foxes (Harris and Yalden, 2008). Urban Fox (Harris and Smith, 1987b) Rural Fox (Reynolds and Tapper, 1995) Cause of death %Killed Cause of death % Killed Road accidents 61.65 Road accidents 7 Killed deliberately by people 17.45 Killed deliberately by people 58 Disease 10.5 Disease 5 Table 3: Major causes of death for urban foxes in Bristol and rural foxes in Dorset. The figures are given as percentages and should be taken to indicate the relative importance of the different mortality factors. 5.2. Disease. Due to higher densities and closer proximity, urban foxes are more susceptible to epizootic diseases such as mange and rabies, this is evident in table 3 (Harris and Smith 1987b). Sarcoptic mange is a parasitic disease that spread across most of mainland Britain during the 1990s, this caused declines in both rural and urban fox populations (Baker et al, 2000). However this decline was more noticeable in urban areas due to higher densities of foxes. In some populations, more than 95% of individuals died. Despite this, populations are slowly recovering (www.thefoxwebsite.org). Harris (1977b) demonstrated that spinal arthritis (sponodylosis deformans), was present in a very high proportion of urban foxes, with an infection level of 34.5%. The average age of the foxes used in the study was only one year nine months. It is thought that development of this disease is related to their diet. Fox (1939) suggested that the situation in urban foxes is unusual; however this has not yet been confirmed by reference to large collections of skeletal material from other populations. 6. Social Organisation and Behaviour 6.1 Territories Davies (1978) recognises territoriality where animals are spaced further apart than would be expected from a random occupation of suitable habitats. The size of fox territory varies largely between regions, depending on their habitat. However territories of the rural fox are generally larger than their urban counterparts. In hill areas of Scotland territories can be up to 4000ha (Lockie, 1964); in rural Dorset it has been averaged at 270ha (Reynolds Tapper, 1995) and as 520ha in Sitka spruce populations (O Mahoney et al, 1999). In urban areas territories may be as small as 8.5ha, this is due to the availability of anthropogenic food sources and the higher density of foxes living in cities. In Bristol the mean territory size is 27ha (Baker et al, 2000), 39 ha in Oxford (Doncaster and Mac Donald, 1991) and 100ha in Edinburgh (Kolb, 1986). The drifting movement of territories appears to be unique among urban foxes and has been studied in Oxford. City ranges were not spatially stable over months or even weeks. They moved in step-wise extensions to encompass new areas whilst at the same time contracting other parts of the range to expel old areas. (Doncaster and Mac Donald, 1991). Movement of home ranges may be a behavioural adaptation that has developed since the invasion of foxes into urban areas. The average amount of food available in the city is usually higher than in an equivalently sized rural area, but there is also a much greater variance in food availability (Doncaster et al, 1990; MacDonald, 1981). Foxes must regularly explore new areas and re-explore old ones in order to make the optimum use of the resources in an urban environment. In a large rural home range this activity would not be viable as it would require far too much energy; however this strategy survives and prospers in cities because of the high de nsity of different habitat patches. 6.2. Relation with Humans Foxes have had a very mixed relationship with humans. They are generally unpopular with rural communities, gamekeepers, shepherds and the majority of farmers (Reynolds and Tapor, 1996). Fox culling in rural areas is undertaken by several disparate interest groups. The key reason for farmers involvement in fox culling is the protection of livestock or poultry. Similarly, gamekeepers undertake culling to protect game on relatively large farms (Llyod, 1980). In rural areas fox hunting as a sport is often of substantial interest. In some cases landowners and gamekeepers curtail their culling effort to ensure sufficient foxes are available for hunting (Heydon and Reynolds, 2000). In contrast with this, urban foxes are welcomed by most residents and are often supported through deliberate feeding by householders (www.thefoxwebsite.org). During the 1970s and 80s there was a large reduction in the number of foxes killed by the local authority, this was due to their increasing popularity in British cities such as London (Harris and Yaldin, 2008). Damage caused by foxes in urban areas is generally slight; however fox predation on domestic pets contributes to the problematic relationship between humans and foxes. In relation to his study of food preferences in urban foxes, Harris (1981b) questioned households in Bristol regarding numbers of domestic animals killed by foxes. 5,191 households took part in the survey. Of the households that owned cats only 2.7% had lost a cat to foxes, most of which were kittens. 7. Conclusion Foxes are found anywhere with adequate food and shelter; their habitat can vary widely in terms of climate and terrain, ranging from the extremes of the arctic tundra in Russia and Europe to the deserts of North Africa (Hutchins at al, 2003). Since foxes have exploited every other suitable habitat, it would be surprising if they had not become city-dwellers. Mac Donald and Nedwick (1982) have suggested that there is no strict division between rural and urban foxes; radio tracked foxes regularly commuted between urban and rural areas. Nevertheless, living in the city requires special adaptations. The features which determine the distribution and abundance of foxes may be different in urban and rural habitats. The habitats of most communities of rural foxes are determined by the availably and distribution of food and by competition for it according to the density of foxes in an area (Goldyn, 2003). In an urban environment food is not usually a limiting recourse as vast amounts of food are available for scavenging. Instead, shelter becomes a high priority and their distribution is determined by the availability of suitable daytime refuge (Harris, 1977a). The diets of urban and rural foxes are generally very similar, however the availability of these foods differ between environments. The same controversy over predation on mans livestock exists in both areas, but in urban areas cats are substituted for lambs and domestic birds for poultry (Harris, 1981, Hewson, 1984). The largest difference in their diets is the more regular supply of scavenged foods and the greater availability of earthworms on domestic lawns than on rougher rural pastures (Doncaster et al, 1990). If given the opportunity, some populations of rural foxes may also scavenge substantial proportions of their food from villages and farms. In urban areas where dense populations of foxes live in close proximity there must be greater social involvement than in the less associated rural fox communities (Baker et al, 2000; Webbon et al, 2004). The closer proximity of high density urban fox populations results in higher susceptibility to epizootic diseases than their rural counter parts (Harris and Smith, 1987b). Density also has an affect on dispersal; generally animals from low density rural areas disperse farther than those from high or medium fox density urban areas (Trewhella et al, 1988). Not only do urban foxes move shorter distances but fewer of them actually leave the home (Trewhella et al, 1988; Storm et al, 1976). In both rural and urban populations humans are responsible for the majority of fox deaths. However, they are perceived very differently in these habitats. The majority of urban fox deaths are accidental (Baker et al, 2004); they are generally welcomed and have provided people with a connection to the natural world. On the other hand, in a rural setting foxes are seen as an agricultural pest and the majority of deaths are caused by culling and hunting (Heydon and Reynolds, 2000). This review highlights the influence of urbanisation on a highly adaptable and opportunistic animal. Foxes have become incredibly proficient at eking out a living in todays world and are deeply entwined in our history and culture.This review ultimately shows that the entire way of life of the urban fox is extremely similar to that of the rural fox; any behavioural differences observed seem to fall within the known range of responses of the fox to environmental stimuli. The specifics of their divergent ecology may differ depending on the habitat they occupy; however the structures of their ecologies remain the same. 8.

Limiting the Use of Technology

Over the past several years’ technology has advanced significantly. Nowadays most everything we use is done by some form of technology. Several years ago, we didn’t even have cellphones or the Internet, now we have cellphones that can access the Internet. This generation has become so dependent with technology that it is actually beginning to harm most us, not help us. So this leads us to believe one should limit his or her use of technology because it could cause addiction, loss of time management, and invaded privacy. Technologies, such as cellphones, Internet, and video games have lead many to be addicted.Because we use cellphones everyday we become dependent on them and use them constantly. Now, when one loses his or her cellphone one gets paranoid and feels as if there is no more hope or life because he or she is so addicted to it. Another sign of addiction would be driving while on the phone. There have been so many cases of people driving while texting or talking on their phone that have caused accidents and deaths. One may see this when a person is a businessman and is constantly on calls, he or she will not put ones phone down because that person is too addicted.Businessmen even bring their work home, they would be eating dinner and they would still take their calls. Obsession could also lead to contently buying items off the Internet or even buying money to play certain games such as, Farmville. Addiction can cause many problems for a person such as, obsession, and the loss of focus towards school and ones job. When a person becomes obsessed over technology such as video games, they soon consume ones life. People find video games exciting as well fun, but what they do not know is that when they continually play them, they can be easily addicted an obsessed with them.Many people waste their lives away just sitting in front of their television playing video games all day and night. Technology can also be a occurring distraction for many an d this can cause many problems. The Internet is one of the many forms of technology we use on a day-to-day basis, and it can be very helpful or very distracting. When we become distracted with the Internet we loose all other priorities that need to be done such as our schoolwork, job, or even children. This is one of the many reasons why we should limit ourselves to the use of technology. By limiting ourselves we are saving ourselves from becoming addicted and obsessed.Secondly, we may end up losing our discipline in time management and cause problems in our lives. When we do not watch how we make use with our time, we can lose track of what needs to be done. Time management is an important factor in our lives and when we lose sight on that we may end up forgetting important tasks. Video games are one of the many technologies we use most of our time doing and keep us from doing our work. Teenagers these days have gotten bad grades and failed classes because they spend too much time playing video games and not much time on their schoolwork.We also end up losing time we could be spending working on our career. Instead of building up our career we tend to waste that time on the Internet or video games. When technologies such as video games or the Internet take the place of schoolwork or our career, we lose all discipline in time management. People who do not have a good time management also will tend to lose friends; they distance themselves by constantly being on the computer or video game. No one wants a person as a friend if all he or she does is play video games and nothing else.When people are losing friends because they are always playing on the computer or video games, we know something must not be healthy. Time management is one of the biggest problems we face when technology is in our day-to-day focus and priority. We also tend to stay inside all day on the Internet or playing video games, and this consumes all the time we could be using for outdoor exer cise and fitness. People can become sick because they are not getting enough exercise through out the day; they become lazy and procrastinate.Staring at a screen is not healthy for your body mentally and physically; it affects your brain and your physical well-being. When our brain absorbs too much ultra violet rays it actually affects our imagination and thought process, and when we sit in front of a screen for a certain amount of time we can actually gain wait and become unhealthy. This is second reason as to why we should limit our use of technologies; they can easily become our number one priorities in life and can ruin a possible future or career. Lastly, since technology has advanced within the last couple of years it has become less private.The more time you put into updating statuses, uploading pictures, and talking to people on line, the more of your personal life will appear all over the world wide web. Every little thing we do online has become less and less safe and priv ate, when we spend so much time on the computer we could end up putting material up we never intended everyone in the world to see. When we spend too much time on sites such as Facebook we become more susceptible to invasion of our privacy, this is when situations can get dangerous.Since the advancement of technology people can hack into other people’s computers and steal passwords and private information we contain. There are so many bad guys out there that when we are so into whatever we are doing online we lose all common sense in safety and privacy. Once people put their information on the Internet there is no way of taking it off, so the criminals could easily find them. Another example would be the use of E-bay; so many people use this constantly and actually are losing money. There are a lot of people out there that will scam you and take your money such as sending fake checks and such.We need to be more careful when we do business over the Internet, it’s not sa fe. This is very dangerous, so how you spend and limit your time on such technologies is important for ones safety as well as another’s. Looking back about 10 years ago when they didn’t have video games, high speed Internet, or cellphones with good connection life was much safer and healthier. People were always outside and when they wanted to talk to someone they would go to them and would have an actual conversation face to face. Nowadays we stay connected with people over the Internet and build relationships online.We have become very lazy in our daily living. If we didn’t spend so much time using the Internet, phone, video game, or television, we wouldn’t have to deal with most of the problems that are occurring now, such as theft, tiredness, laziness, and obesity. Some of the causes of these problems would be addiction, loss of time management, and invasion of privacy. Technology, nowadays have become the main source of most of our crimes, problems, and accidents. By limiting our use of these technologies we limit the problems that will potentially occur.

Museum of Art Essay

After visiting the Raleigh Museum of Art, I discovered two paintings that conjured up opposite feelings that I will compare and contrast. The painting I liked most was titled, Jungle Camp, 2000 an Acrylic on canvas 72 x 60 in. (182. 9 x 152. 4 cm), from one of North Carolina’s most respected artists, Maud Gatewood. Her paintings record the varied experiences of a wandering life. Writing on the back of the canvas, the artist notes the origins of this picture: â€Å"Trapped in the Amazon with a bad leg†. Confined to a hut, she made the most of the opportunity. The second painting titled, Venice without water, by North Carolina’s artist Donald Sultan was the painting I truly disliked because of the feelings it provoked. Sultan’s painting from 1990 was an acrylic painting and measured 96 x96 inches in dimension. Sultan used Butyl rubber, acrylic paint, and plaster on vinyl composite tiles, which were mounted on four Masonite panels. Both painting represent landscapes captured by the artists’ eyes or through a photograph. These paintings gave me two strong, but opposite, feelings: joy and sadness. I will describe the differences and contrast these two works of art. The two pieces of art works have several differences in style. First, the shape in the painting, jungle camp, is rectangular; while the second painting is square. The choice and use of color in the two paintings are completely opposite. Since color is most important to me, I chose the jungle camp painting due to the variety of bright colors that pop from canvas. The painting from Mrs. Gatewood is colorful, which gave me a feeling of joy and warmth. However, Sultan decided to use contrast instead of colors in his painting. Thus, Sultan’s painting is filled with different tones of grey, black, or white. Gatewood’s painting represents a jungle’s view from a patio or balcony. I can see tall palm trees all stuck to each other in her painting, which gives the impression of abundance and fertility. She chooses many different variations of green. For example, she utilizes certain hues of light green to create an effect of sun reflection. There are two types of curtains on the patio, hanging on a fine line. The first is really colorful, a mix of tropical color, and the second is like a white veil, which you can see trough it. The mix of materials and colors for the curtains, added to the jungle, procures me a sense of evasion, vacation, and relaxation. I was drawn to the atmosphere of serenity and tropic jumbled together, which is the reason that this painting evoked my interest. However, Sultan’s painting is the exact opposite of abundance and excursion. The whole artwork is quite dark and sad. It’s a representation of the well-known Rialto’s bridge, which is an infrastructure between to planes. The first plane is an illustration of wood’s pillars, which surround the Venetian canals; they are use by the gondoliers to park their â€Å"original dinghy†. The second plane is the bridge; it looks pretty scary and dark with no one crossing it. The final plane, which is the background, consists of some Venetian’s buildings. These buildings form a line that converges towards the bridge; which helps my eyes focus on the main subject the bridge. Sultan’s painting does not reflect the Venice that I saw five years ago. When I think about my trip to Venice, I have an enriched memory filled with bright colors from the Carnival. I remember vivid colors on all the masks, costumes, life, and crawl of people. Sultan’s artwork doesn’t have any of my souvenirs. Instead, the painting is more like a sinister version of the beautiful city, Venice. Although I do not like this particular outlook of Venice, I realized after studying his painting that the artist is expressing his environmental point of view of the city, which I completely agree with. As an admirer of this city, I feel concerned by the environmental issue depicted in the painting. The notion that the excess of tourism could be destructive to a fragile city like Venice is a valid concern. The artist conveys his dismay over â€Å"the deteriorating environment with the unused mooring posts, the dry canal bed of mud-like tar, and the melancholy mood of the painting†. I think that colors or tonalities are the essence of the painting, like the rhythm and tunes are for music. In my view colors are strongly subjective, they can have different psychologist effects and symbolist’s significations, they can differ from a culture to another; associating Black with mourning is normal, in our occidental countries, while in Asia it’s the actual opposite, White. In my case the colors are the main cause, on what I think is pretty or not.
