An Introduction to the Scottish Nature

...Scotland Scotland. The place where thousands of nature-loving people are drawn to, just to breathe in the intoxicatingly clean Scottish air and to feel the heartbeats of the Highlands. It is an ancient and magical place, where beauty isn’t a description, but a fact. From the Highlands to the lochs and lakes brimming with crystal clear, icy cold water, the country seems to have a never-ending abundance of nature reserves, parks and woods. But what is it that makes the Scottish nature so special and loved? How does the nature affect the native Scottish people and the tourists? And also, how do they affect the Scottish nature, will it look the same for the future generations? To answer the first question, we have contacted a specialist on the subject. It’s (?....?), who has been doing research on the matter for almost half a decade: “….” If you have ever had the privilege of visiting Scotland, you will know just what an incredible wealth of natural treasures it possesses. The fine scenery is inspiring to live in and visit, and the imagery of an unspoilt landscape is important in the marketing of Scottish brands selling products such as whiskey. The nature is also important in the marketing of tourism, in fact some cities across the Scottish landscape rely almost entirely on the tourists coming there to experience the wildlife. One of those cities is Oban. Oban is a town known for its tasty whiskey; the city is actually built around the Oban Whiskey Distillery. Nowadays,......

Size Task

...Publishing Inc. Printed in the USA. Copyright r 2006 Society for Psychophysiological Research DOI: 10.1111/j.1469-8986.2006.00392.x When does size not matter? Effects of stimulus size on affective modulation ANDREA DE CESAREI AND MAURIZIO CODISPOTI Department of Psychology, University of Bologna, Bologna, Italy Abstract Motivationally relevant stimuli have been shown to receive prioritized processing compared to neutral stimuli at distinct processing stages. This effect has been related to the evolutionary importance of rapidly detecting dangers and potential rewards and has been shown to be modulated by the distance between an organism and a faced stimulus. Similarly, recent studies showed degrees of emotional modulation of autonomic responses and subjective arousal ratings depending on stimulus size. In the present study, affective modulation of pictures presented in different sizes was investigated by measuring event-related potentials during a two-choice categorization task. Results showed significant emotional modulation across all sizes at both earlier and later stages of processing. Moreover, affective modulation of earlier processes was reduced in smaller compared to larger sizes, whereas no changes in affective modulation were observed at later stages.

Scottish Independence

...Unit 3: Thinking Report ‘Scottish independence’ Lauren Pratt – 1200370 As the SNP came to authority four years ago there has been a surge of interest across the country. Becoming independent will mean the people who care most about Scotland will be taken the decision about our future. A debate was presented by Stewart Hosie, a Member of Parliament for Dundee East, who was in favour of the motion besides Jenny Marra, who was the second presenter, who is a member of the Scottish Parliament for Dundee North East, Scottish Labour, was in opposition to the motion. Stewart Hosie gave an analytical, quantitative and fact driven argument. Jenny Marra gave a biographical, personal and historical argument. Both played a conception of their audience as largely conservative. In the debate ‘It is time for Scotland to become independent,’ presented on the 17th of September at University of Abertay, Stewart Hosie stated that for many countries, independence is taken for granted, and Scotland should be given that opportunity also. The biggest part of his argument was a number of statistics which he used to show the sustainability and competency to succeed of an independent Scottish nation by use of taxation, and by exploitation of the North Sea. He encouraged that large manufacturing plants should be returned to Scotland, and through these opportunities, this nation would thrive if no longer dependent on the rest of the UK. On the other hand Jenny Marra took a less statistical......

Scottish Enlightenment Social Theory

...This essay seeks to define why the Scottish Enlightenment theorists rejected previous attempts at social theory and instead formulated their own social theory. It also seeks to define what was scientific about their approach compared to other theorists who formulated other social theories. Firstly the enlightenment will be defined and previous attempts at social theory outlined. Secondly the theorists social theory will be outlined and finally a discussion of why their approach could be considered scientific. This essay will argue that it was the theorists’ departure from conjecture and sermon which made their theory so radical for its time, and their application of the new framework of Newtonian science which allowed their application to be considered scientific. The enlightenment was a period of philosophical thought and intellectual development which began in the eighteenth century (Ritzer, 2010). The enlightenment theorists sought to combine empirical research with the developing model of Newtonian science. The theorists were convinced that the world around them could be understood using reason and research and that the institutions which governed social values and societal norms were rooted in irrationality and actually acted to inhibit human development (Ritzer, 2010). The theorist’s arguments clashed with the conjectural and traditionally espoused history of the social institutions such as the Church and the political regimes of the countries they operated in......

Case Study: Chest Sizes of Scottish Militiamen

...Case Study: Chest Sizes of Scottish Militiamen. a.) Construct a relative-frequency histogram for the chest circumference data, using classes based on a single value. b.) The population mean and population standard deviation of the chest circumferences are 39.85 and 2.07, respectively. Identify the normal curve that should be used for the chest circumferences. “The associated normal curve is the one whose parameters are the same as the mean and standard deviation of the variable…” (Weiss, pg. 256). Thus the parameters used to find the normal curve for chest circumferences are µ = 39.85 and σ = 2.07. c.) Use the table on page 254 to find the percentage of militiamen in the survey with chest circumference between 36 and 41 inches, inclusive. Note: as the circumference were rounded to the nearest inch, you are actually finding the percentage of militiamen in the survey with chest circumference between 35.5 and 41.5 inches. In order to find the percentage of militiamen with chest circumferences between 36 and 41 inches, we must add the frequency of these variables, and then divide by the total observations. 189+409+753+1062+1082+935=4430 4430/5732 = .7729 77.29% d.) Use the normal curve you identified in part (b) to obtain an approximation to the percentage of militiamen in the survey with chest circumference between 35.5 and 41.5 inches.

Scottish Independence

...Scottish independence- pros and cons from the economical point of view Essay Recently the Scottish referendum and especially the economic consequences of Scottish independence became one of the most interesting and controversial world topics. The most common view is that Scotland needs the rest of the UK and the economic and social factors of independence would be too great to deal with. Many people think that going independent is an extremely large economic gamble and will lead to many unwanted consequences - lack of national resources, economic crisis because of investors’ uncertainty, higher tax and interest rates, currency problems, change in the economic and political relationships with European union and other countries. In its unity with the UK, Scotland is part of a very powerful, rich and influential state. This confers all kinds of useful economic benefits, including low interest rates, a seat at the UN Security Council, leadership in NATO and other multinational organizations. So becoming independent would significantly decrease Scotland's global presence and influence. The choice of currency will also lead to wide ranging economic implications. An independent Scotland would, in theory, have three main currency options: its own currency, using the Euro and continuing to use the pound. The European Union has ruled out Scotland joining the euro (or even the EU). So if an independent Scotland did not join a currency area with the rest of the UK, its main option......

Super Size Me

...Super Size Me Assignment To begin with, I have seen this movie Super Size Me before in high school. This is my second time watching it and I am still shocked by what is said in this movie. With that being said, I do eat fast food quite often. I eat it about 2-3 times a week. I do not live at home so I no longer get home cooked meals from my mom. I try to cook by myself sometimes but there are only so many things I know how to make and is sometimes more convenient for me just to drive down the street and get Del Taco or Weiner Schnitzel’s. Also with work and school I try my best to bring my own lunch or eat at a restaurant rather than going to a fast food joint. This film relates to the NF15 course in many ways, one of them being that when the narrator interviewed random people on the streets, nobody knew what a calorie was. This shows that people hear the word calories and see it on every food label and everywhere they look that there’s food, but still do not know what it is. This goes to show that people do not generally care about calories and how much they take in. Most people who eat fast food also do not know how many calories they are taking in from the food that they ordered. The foods ordered from fast food restaurants do not have food labels and only some will give you a nutrition facts sheet if asked for one. The film also showed that an order of small fries had 200 calories while the large order had 600 calories. That is 3 times the amount of......

Case 16.3: Diagnosing Chest Pains

...Case 16.3: Diagnosing Chest Pains One evening during the summer of 2012, a Con- necticut woman experienced chest pain (Brill 2013). She took an ambulance to a local not-for-profit hospital. After several hours in the emergency room, she was sent home with a diag- nosis of indigestion. Shortly thereafter, she received a bill of $995 for the ambulance, $3,000 for physicians’ services, and $17,000 for the hospital. A major part of the hospital bill was a $7,998 charge for a CT scan with con- trast. (The Medicare rate is $554.) The alternative to the CT scan would have been a stress test using an electrocardiograph. Its list price was $1,200 and the Medicare rate was $96. Unfortunately for the patient, she was not offered this option, was uninsured, and was a year too young to be eligible for Medicare. When questioned about the bill, a hospital representative said, “I’ve told you I don’t think a bill like this is relevant. Very few people actually pay those rates.” Nonetheless, the patient was asked to pay it. A medical billing advocate was able to negotiate a $10,000 discount but made it clear that she thought even this amount was excessive. Discussion questions: • After reading this case, would you be more or less willing to have a CT scan done if an emergency room physician recommended it? If I am going to the emergency room (ER) then for me it will be a true emergency and I will more than likely do whatever the doctor recommends no......

Super Size Me

...The Film Super Size Me Ethical Paper Zhen J. Huang California State Polytechnic University, Pomona Introduction Take a look around when you go out, what do you see? Loads of fast food restaurants? Maybe McDonalds is the exact name. In the documentary film Super Size Me, filmmaker Morgan Spurlock (2004) shows that fast food has become a fixture in the American culture, as well as other countries’ cultures. As Spurlock (2004) said in the film “what would happen if I ate nothing but McDonald’s for 30 days straight? Would I suddenly be on the fast track to becoming an obese American? Would it be unreasonably dangerous?” For this paper, I am going to discuss about the concerns of fast food, namely McDonalds by using three ethical theories: Hedonism, the Desire Theory, and Ethical Egoism. Hedonism: The Pleasure of the Super Size As Rabinowicz and Ronnow-Rasmussen (2005) explains, “an object is thought to be intrinsically valuable … depends on … final value if it is valuable ‘as an end’, ‘for its own sake’, rather than for the sake of something else” (p. 115). The kind of pleasure hedonists claim is always intrinsically valuable is health. If people know that they are healthy and are free of sickness or pain, they are living a good life, and a good life is a happy life. Basically, health contributes to happiness and the happier the person is, the better his/her life is going to be. According to Veenhoven (2003), “There is a longstanding discussion about the merits of......

The Creative Industries and Scottish Film.

...The Creative Industries and Scottish Film. With its exquisite landscapes, monumental architecture, and breath-taking coastlines, it is no wonder Scotland has always been such a powerful draw to film makers and producers alike. The Scottish film industry has grown from strength to strength in recent years. Arguably putting itself on the map in the nineties with films such as Braveheart (1995) and Trainspotting (1996), Scotland now lends its locations to multimillion-pound productions such as Skyfall (2012), The Dark Knight Rises (2012), Sunshine on Leith (2013) and The Railway Man (2014) as well as TV productions including Game of Thrones (2011) and Outlander (2014). To what extent have Scottish films such as Braveheart and Trainspotting impacted on the tourism industry and given their contrasting portrayals of the Scots, does one hinder tourism more than the other? Can we say whether or not there is a distinct notion of ‘Scottish national identity’ and if such a concept exists to what level is it illustrated in Scottish film? Has the Scottish film industry had an impact on the political landscape in Scotland since it was devolved in 1998? Finally given the effects of Scottish film in Scotland, what has the government put in place in order to develop the industry further? Scotland has produced many world renowned films over the last two decades and has had a large impact on the creative industries in Scotland. It has long retained a certain romance which frequently......

Susidies to Scottish Farmers

...With reference to figure 1, Extract 2 and your own knowledge, discuss the reason for subsidies being paid to Scottish farmers. A subsidy is a grant given by the government which lowers the price of a good, usually designed to encourage production or consumption of a good. Subsidies lower production costs, this comes from a decrease in unit cost, and this could possibly come from an investment in capital stock by Scottish farmers, which leads to more efficiency in production, which leads to a decrease in production cost. A decrease in production cost means an increase in supply which means a decrease in price, also a decrease in a price of a good leads to an increase in demand. The quantity supplied has increased due to lower production costs; this has lead to a decrease in price from P1 to P2. The quantity supplied has increased due to lower production costs; this has lead to a decrease in price from P1 to P2. The quantity demanded has increased from Q1 to Q2 due to the reduction in the cost of production, this has increased output. The quantity demanded has increased from Q1 to Q2 due to the reduction in the cost of production, this has increased output. Due to lower prices, from a decrease in production, goods from farms such as meat and vegetables have become more affordable for those who could not afford it before; this is mainly referring to the poor. Due to more people being able to afford goods like meat and vegetables, the consumption......

Chest Pain

...Chief Complaint: “I am having chest pain.” Question One: Please describe your chest pain in terms of it being a new or prior symptom, onset, duration, radiation, quality, what makes it worse or better, and describe the location(s) felt. Rationale: Understanding the patient’s pain gives a perspective of potentially what or where the underlying etiology could be, or where to start as a focal point for the assessment. Priest (2012) assert that there is a multiplicity of conditions that could cause chest pain, which includes an acute myocardial infarct, pulmonary embolus, thoracic-aortic aneurysm or dissection, gastroesophageal-reflux disease, chest-wall pain, a muscle pull, inflammation in the lining of the lung from a viral infection, and gallbladder or pancreas problems. Dodaro (2015) states that the experience of chest discomfort lasting longer than a couple of minutes or chest discomfort that comes and goes might signal an emergent condition and the clinician should test for the most urgent causes first. Diagnostic testing should be the focus of ruling out the potential differential diagnosis associated with the highest morbidity and mortality is the nature of the chest pain is unknown, which is AMI, PE and aortic dissection. Associated potential normal and abnormal findings: • Coronary angiograms will indicate an abnormal finding of a blockage in one or more of the coronary arteries. • Women's heart attack symptoms, signs, and treatment differ from men's,......
