See Some Triboluminescence Examples

You may be familiar with the Wint-O-Green Lifesaverâ„ ¢ spark in the dark, but if you dont have Lifesavers handy, there are other ways you can see triboluminescence. Triboluminescence results from the fracture of (usually) asymmetrical materials. The break separates electrical charges, which recombine and ionize the air. The ionization of nitrogen in the air produces ultraviolet light, but you cant see that. You can observe triboluminescence when another material is present that absorbs that ultraviolet light and re-releases it in the visible range (fluoresces). Here are some examples: Cracking Wint-O-Green LifesaversCrush a wintergreen-flavored Lifesaver candy with your teeth or a hammer. You get triboluminescence whenever you smash sugar, but there usually isnt enough light for you to see it. The methyl salicylate in the wintergreen oil is fluorescent and converts the ultraviolet light into blue light. If you cant find this flavor of Lifesavers, you can use sugar with wintergreen oil or clove oil.Unwapping a Band-Aidâ„ ¢Some Band-Aid wrappers will emit a blue-green glow when they are unwrapped quickly. While you can unwrap the bandage in the dark, youll probably want to turn the lights back on before applying to a wound!Cutting a DiamondThis is not something most of us are likely to do, but some diamonds will fluoresce blue or red when being rubbed or, more usually, cut.Unrolling Friction TapeFriction tape is that cloth tape that has a rubber adhesive such that it is sticky on both sides. It can be used as an electrical insulator, but youll usually see it in t he context of sports, to wrap hockey sticks, tennis rackets, baseball bats, etc. If you unroll friction tape in the dark youll observe a glowing line as the tape is pulled away from the roll.Opening Sealed EnvelopesThe adhesive used to seal some envelopes will fluoresce blue as the contact is broken.Remove Ice from the FreezerThis is an example of fractoluminescence, which is sometimes considers synonymous with triboluminescence. Fractoluminescence is light produced by fracturing a crystal. The fracture separates charge. If enough charge is separated, an electrical discharge may occur across the gap. If you remove ice from a freezer in a dark room, you may see flashes of white light accompanying the crackling sounds of ice undergoing rapid thermal expansion.

Analysis Of Martin Luther Small Catechism - 1256 Words

The Small Catechism was written in 1529 by Martin Luther. He wrote it after he visited with common people and saw a severe lack of instruction by both the head of the households and pastors on how to lead a good Christian life (Deuteronomy 6:5-9). He was so upset he noted; â€Å"the wretchedness I beheld† and said â€Å"many pastors were quite incompetent and unfitted for teaching† (Preface to Small Catechism) (LC: Live Session). The Small Catechism is a handbook to Christian Doctrine and Christian Living. It includes the 10 Commandments and how to follow them, the Lord’s Prayer, introduction to Christian Life, Baptism, Lord’s Supper and how the Holy Spirit brings the Lord to u (LC: Table of Duties). Luther’s Small Catechism is written in a†¦show more content†¦Charles V was resistant to the reforms wanted by Lutherans and wanted to condemn Martin Luther for heresy. The confession was written as a script for the princes about reform. Ho wever, so many other princess read the confession and signed and it became a confession of the Lutheran beliefs (LC: Charles V) (Romans 11:6). John Fredrick - Elector of Saxony knew how to use the political system of the greek empire and help lead this reform movement (LC:John Fredrick). The Augsburg Confession is the basis of the foundations of our belief and clarifies our instructions given to us in God’s holy Bible. It is the center of the Book of Concord because it looks back to the creeds and forward describing our confessions of living a good Christian life (LC: The Augsburg Confession). The Apology to the Augsburg Confession was written in 1531 by Philip Melanchthon. He wrote it because the Roman Catholics did not give the princes a chance to reply to the Augsburg Confessions. We can see clearly in Melanchthon’s writing his method of centering message in Jesus Christ (LC: Apology of Augsburg). â€Å"After the Roman theologians had condemned many of the teaching of the Augsburg Confession, Melanchthon authored this lengthy defense (Book of Concord, page 15). This was the Lutherans strongest defense of justification by faith (Article 4) (Genesis 15:6; Romans 4 1:5).

Answer: 1: Observations on a particular trait or character that are distinguishable or countable are called variables. A variable can be any number or measurement or characteristics whose value can vary over a certain range. Income of a person in a month is an example of a variable. Income of a person can take any values starting from 0. Age of students in class, the color of a flower, the number of books in a library is other examples of variables. Variables are classified into two types. By counting, the variables are categorized in to Qualitative and quantitative variables. Variables that can be counted are called quantitative variables. Age of students, the number of books in a library is examples of quantitative variables. On the other hand, the variables like the color of a flower, the first letter in the number plate of a car cannot be counted. These variables are referred to as qualitative variables. A quantitative variable can be classified into two types-discrete and continuous variables. Variables that can take values only a discrete set of points are referred to as discrete variables. While, on the other hand, if a variable takes values on a continuous scale then it is known as continuous variables. Number of books in a library, the number of people in a household is examples of discrete variables as these variables take distinct values. Height, weight, age are examples of continuous variables. Qualitative variables are also referred to as categorical variables as they describe a particular characteristic of a data point like to which category the data point belongs. Categorical variables can be of two types: Nominal variable: The categorical variables that cannot be arranged in an increasing or decreasing order are called nominal variables. Nominal variables can only be classified into a particular group. Type of business, eye color of a person is examples of nominal variables. Ordinal variables: The categorical variables that can be arranged in an increasing or decrease order are termed as ordinal variables. Grades that are given in an examination, any attitude towards a decision (disagree, agree, moderate, strongly agree) are examples of the ordinal variable. Two independent groups of variables can be compared using a different test. If the variables are quantitative, then t-test can be performed to test the whether the two groups are independent. If the variables are qualitative, then a two sample proportion test can be performed. The t-test can be used for the test of equivalence of two means of two independent samples. The hypothesis is given by H0: 1= 2 against H1: The means are unequal. The statistic for the test is: If the calculated t value greater than tabulated t value then the given hypothesis is rejected. The rejection of hypothesis implies that the two means are equal. If the variables are quantitative, then test for proportion can be performed. The hypothesis to be tested is p1=p2 against H1: proportions are unequal. The test statistic is given by Z= /s.d S.d=sqrt((p(1-p)(1/n1+1/n2)) Where p1 is the estimated proportion of the first sample and p2 denotes the estimated proportion of the second sample. "n1" and "n2" are the sizes of the two samples. The test statistic is rejected if the calculated p-value is less than the level of significance . The limitation of t-test is that the underlying distribution of the sample is assumed to be normal. If the distribution is not a normal distribution, then a robust statistic like median has to be used. Then the median test can be performed. In the median test, the hypothesis to be tested is H0:me1=me2 against H1: me1me2. In the proportion test, the sample variance is the pooled variance of the two samples. Pooled variance can be assumed if the variance of each group is more or less same. If the two groups greatly differ by variance, then pooled variance cannot be used. In that case, test for proportion is invalid. 2: Box Plot: Box plot or box and whiskers plot is a way to represent statistical data graphically. A box plot is also termed as box and whiskers plot. The lines that extend vertically from two sides of the box are called the whiskers. A box plot is a nonparametric representation. It does not assume any underlying distribution. The Box in the box plot is the space between first and the third quartile. Outliers can be easily detected with the help of box plot. The box plot gives an idea about the spread or dispersion of the dataset. Any box and whiskers plot depicts the following statistical measures: Median: The median is the midpoint of the data and is represented in the box plot by the line inside the box. From the position of the median in the box plot, one can determine whether the distribution is skew or symmetric. Sometimes an additional line for the arithmetic mean is also given inside the box. If the mean and median line coincides, then the distribution is symmetric. Otherwise, it is skewed. Quartile: 75 percent of the observation falls below the first quartile, and 25 percent of the observations fall below the first quartile. Range: It is the difference between the minimum and maximum observation in a dataset. Interquartile range: Interquartile range is the length of the box.50% of the observations are expected to lie within the range. Outlier: Any outlier if present is detected in the outside the interquartile range. The outliers lie between the points 1.5 IQR and 3 IQR. Addition law of probability: Two events A and B are considered. The events are mutually exclusive if the probability of their intersection equals zero. Two events are collectively exhaustive if the union of the two events makes up the entire sample space. P( Addition law of probability states that A1, A2,,, An be n events The events possesses the above two properties that are the events are events collectively exhaustive and mutually exclusive. Then the probability of the union of the events is equal to the sum of their probabilities. Retrospective study: A retrospective study refers to the longitudinal study design of two cohorts. In this kind of study, one cohort is exposed to particular disease and another cohort is not exposed to the disease. The two cohorts are compared to identify the factors in their history that can be associated with the disease. The data are collected from past values. The study is mainly conducted to determine the risk associated with the disease and to estimate the number of causalities from the disease. The risk ratio or Odd ratio of the two groups is calculated which gives the relative risk of the disease in the particular cohort. The Risk ratio is given by the following formula: DISEASE PRESENT DISEASE ABSENT Group1 A b a+b Group 2 C d c+d a+c b+d n Then risk ratio is given by Odds ratio is given by: OR=ad/bc If the value of Risk ratio is greater than one, then, the cohort has a less chance of developing the disease.If the value of risk ratio is greater than one, then the cohort has a higher chance of developing the disease. Same interpretation also applies for the Odds ratio. The advantages of Retrospective study is that it is less costly, less time consuming and could easily be conducted and gives a better comparison of disease between the cohorts. For example, if one wants to compare the oral health status of two groups, an idea about the oral health status of the new generation can be obtained from the oral health status of the mothers. R-squared: R-squared values are calculated to determine how good a fitted model is. The R-squared value is the ratio of the residual and total sum of the squared values. The greater the value of R squared statistic in the case of a regression model; the better is the fitted model. R-squared=RSS/TSS. A good model is expected to have the minimum error. The sum of errors is equal to zero. To make a comparison, squared sum of errors has to be considered. The smaller the value of RSS or residual sum of the square the better is the model. So more the value of R squared, the better is the model. R-squared value does not consider the number of parameters involved in a model. For a model to be good, the model should be parsimonious. For this, another measure of R-squared is developed which is called adjusted R-squared. The adjusted R-squared measure is given by the following formula: R-squared (adjusted)= 1- (RSS/n-k)/(TSS/n-1) .K is the number of parameters. So higher the value of adjusted R-squared the better is the fitted model regarding both parsimony (minimum no of parameters) as well minimum errors. Cluster Sampling: Sampling is the procedure in which only a drawn sample from the population is considered for the purpose of statistical computation. Cluster sampling is an efficient sampling procedure where the total population is at first divided into some clusters and then the sample is collected from this clusters. The clusters are made as homogeneous as possible. Cluster sampling can be one stage or two stages. For example, for obtaining sample of household expenditure from a city, at first, the city can be divided into several blocks according to locality and then sample could be collected from each of the blocks. These blocks form the cluster. Standard error of a mean: The average sample value is an unbiased estimate of the average value of a population. The deviation of the mean of sample from the population mean value is the error. The standard deviation of the mean of sample value is called the standard error of the mean. 3: Inter-rater reliability is used to measure the extent to which two observers agree whether the teeth are carious or not. Inter-rater reliability is used in case of subjective judgment. If the rating scale is continuous, then Pearson's product moment correlation is used. If the rating scale is ordinal, then Spearman's product moment is calculated. For the case of a categorical variable, Cohen's Kappa is used. The formula for Cohen's Kappa is: Where O is the observed agreement, and E is the expected value of the agreement. N is the total sample size. The failure rate is used to measure the extent to which an observer agrees with the gold standard test. The failure rate is given by f(t)/R(t) where f(t) is time to failure of an event and R(t)=1-F(t).F(t) is the cumulative distribution function of t. C.ROC curve is drawn to discriminate between the presence or absence of a disease.ROC curve is drawn by plotting FPR against the TPR. The FPR is equal to (1- specificity), and true positive rate is calculated by sensitivity. Sensitivity refers to the proportion of population with the disease tests positive. Specificity relates to the part of population without the disease testing negative. The area inside the curve of ROC helps to determine the level of discrimination between the individuals with test positive and individual with test negative. The underlying principles of the ROC curve are: The threshold value for drawing the ROC curve influences the specificity and sensitivity values. The threshold value should be so chosen that distribution of test results for presence or absence of disease should not overlap. In most of the cases, the two distributions overlap. But in most of the cases, the two distributions overlap. So the diseased people are misclassified as normal people. Lowering the threshold value will increase specificity while higher threshold value decreases specificity. 4: The mean of a variable that is to be calculated is the sample mean. The population mean is different from the sample mean. In a practical situation, a confidence interval with confidence coefficient 95 for any statistic gives the probability that the value of the mean lies within the interval with confidence limit 95%. That means if the sample is repeated as many times as possible, the probability that the mean value lies within the interval is 0.95.if the distribution of test statistic is standard normal, then the confidence interval is given by the following formula: Ucl=xbar +s/sqrt(n)*z Lcl= xbar-s/sqrt(n)*z Again if the test statistic follows a t distribution, then the upper and the lower control limits are given by: Ucl=xbar +s/sqrt(n)*t Lcl= xbar-s/sqrt(n)*t The t statistic is generally used in case of confidence interval if the standard deviation value is to be calculated from the sample. If the population standard deviation value is given then, one can use z test to determine the value. 5: The following methods are used for analysis of dental data: One way ANOVA: One way ANOVA or variance analysis is carried out to test whether the means of several groups are equal or not in the case of fixed effect model and equality of variance of several groups in case of random effects model. In one way ANOVA, there is only one factor affecting the values of the variable. The one-way ANOVA model is given by: Where yij represents j the observation in the ith cell. is the common mean effect and i is the effect due to the ith group and eij is the error assumed to follow N(0,^2) distribution. The random effect model is given by Yij=+ai +eij , where eij is the random effect due to the ith group. An example where ANOVA test can be conducted in dental study: One wants to measure the performance of five brands of toothpaste that heals tooth sensitivity. Certain volunteers are selected and each of them is given a brand of toothpaste to use. After the completion of one tube, the patients were asked to give a score about how their sensitivity problem is. The mean score from each volunteer is collected, and the mean scores are tested with the help of ANOVA, and the toothpaste that performs best can be found out. ANOVA test has certain assumptions: The error is distributed as normal with zero mean and uniform variance ^2 across all groups. The observations are supposed to be independent. If the above assumptions are violated, then ANOVA test cannot be carried out. Besides, ANOVA can tell only if all the means are equal. If the means are unequal, then one has to perform t-test to compare two means. Survival Analysis: Survival analysis determines the time to failure (or survival) of an event. Survival analysis is particularly useful in case of censored data. For example, if one wants to find the time required f or recovering from a disease then survival analysis can be used. Survival Analysis can be used to study a particular impact of certain dental surgery on the patients. For this analysis, one can study the time to the occurrence of the event(death) of the patient along with other factors. The study can be done with the help of Kaplan-Meir estimator. If there are several factors affecting the time, then a regression model such as Cox model of proportional hazard functions can be used. This analysis aims to study the time to occurrence of an event. It gives the chance or probability of survival from a particular disease. Survival analysis also takes into account the effect of other covariates over time to survival. But survival analysis has certain limitations. The limitations of Survival regression is same as that of ordinary regression problems. The statistical data and real life data are different. So the estimates from survival analysis are valid up to certain extent and may not be true for every case. The error in survival models is assumed to be normally distributed. Another important feature in survival analysis is censored observations. If the number of edited cases is too many, then survival analysis can lead to faulty results. C.Log transformation: Log transformation is used in the following cases: 1.To make the data skewed: Log transformation is mainly used to make a skewed data more less skewed. Taking logarithm of the values, one can compare the geometric mean of the values instead of arithmetic mean. For example, if the brain weight of a person is plotted with body weight then the distribution is skewed as the body weight is very large as compared to brain weight. Plotting the log-transformed variables, the distribution becomes less skewed. 2.Log transformation is used if the dependent variable is discrete or binary and the response variables are continuous. By taking logarithm of variable, the response variable can be converted into a discrete variable. This often happens if the response variable is dependent on some categorical variable. To standardize the data: Sometimes data do not follow normal distribution. Taking a log transformation of the values will make the data follow normal distribution. Log transformation has certain limitations. It is not applicable to confounded data. Data point has to be independent. Otherwise, change is not useful. D.T-test: This is a test of paired sample observations which is used to test the dependence of the arithmetic mean value of two variables. Paired sample t-test can only be done if the sample size of two samples is equal. In paired sample t test the difference of each observation is calculated. Let di denote dit. The mean of the observation is tested to be equal to zero or not. The hypothesis of interest is to test H0: The mean value of the paired observation is equal to zero against H1: not H0.and the test statistic is (dbar/sd) where dbar is the mean of di and sd is the standard deviation of di values. The statistic for performing the test is said to follow a t distribution. In this case, the d.f will be equal to n-1 where n is the sample size. The limitations of paired t-test are that it is applicable when the groups have same sample size. If the sample size varies then, another t-test has to be performed. It is also applicable to datasets that have standard normal distribution. If underlying distribution is nonnormal, then nonparametric tests could be performed. 6: The DMF index is a method used in dentistry for testing dental caries. The dmft of males between 12 to 14 years of age is six as claimed by a certain researcher. So to support this claim a test has to be conducted. A sample has to be drawn from the population of males between the age group 12 to 14 years. Then the mean value of dmft obtained from the sample has to be tested. The hypothesis that has to be tested in this case is whether the mean or median of the population is equal to 4 or not. H0: = 6 against h1: six where represents the mean of the distribution. Or, h0: me=6 against h1: me6. The distribution of the population of males can be assumed to be normally distributed. In that case, one can test whether the mean value is equal to 6 or not. The mean value of the population can be estimated by sample mean. Then the problem is to test whether the sample mean value is less than a particular value. If the population does not follow standard normal distribution, then a nonparametric test for median of the observation can be done. If the population distribution is assumed to be normal, then a test for the sample mean could be performed. Then the problem is to test h0: =6 against h1: 6. If the value of s.d of population is known, then z-test can be performed. If the population value of standard deviation has to be estimated from sample value, a t-test has to be performed. The statistic for the z test is given by: Z=( - )/ where is the sample mean. The test statistic for t distribution is: T=( - )/s where s is the s.d of sample. Interpreting test results: A test is rejected if probability value of the test is less than level of significance. H0 is rejected if z-value is greater than z/2 at level of significance . Z/2 is the tabulated of value of upper alpha point from the standard normal distribution table. In case of t test the null hypothesis is rejected at level of significance if tt value determined from sample is greater than tabulated t value at the level of significance /2 at degrees of freedom n-1. The size of the sample is important in case of performing a test. The accuracy of a test depends on the sample size. The value of sample size is given by the following formula: N = (1.96*sigma^2)/e^2 .here sigma denotes value of standard deviation. E denotes the correction limit within which the value of the mean that is to be estimated.

The Debate of the Single Currency Concept Essay Example Essay Example

The Debate of the Single Currency Concept Essay Example Paper The Debate of the Single Currency Concept Essay Introduction The Euro argument is intensely emotional. Whilst on the one manus Trichet describes the Euro as â€Å" [ T ] he coronating accomplishment of the individual market † ( 2001, p.7 ) , others believe that the Euro is nil less than a confederacy to make an ( immorality ) European super-state. There can be no uncertainty that this is an of import issue, peculiarly in the United Kingdom given its authorities ‘s â€Å" definitely-maybe † positions on the Euro. Consequently this essay will see the Euro inquiry with peculiar mention to the UK. First, it will see the statements for and against the UK come ining the Eurozone. Section 2 sets the scene by sketching a brief history of the Euro. Section 3 so describes the celebrated five trials set by Gordon Brown to enable a determination upon the annoyed inquiry of whether Britain should fall in the Euro. Section 4 considers the political facets of the argument, which this author sees as the existent issue in this argument. Sec tion 5 examines life outside the Euro, and its deductions for the UK. Finally, subdivision 6 draws decisions on the Euro argument. The Debate of the Single Currency Concept Essay Body Paragraphs The route to the Euro began in the Maastricht Treaty [ 1991 ] , which agreed upon a common currency. The so British authorities ( Major ‘s conservative authorities ) , nevertheless, was profoundly doubting about this, seeing pecuniary brotherhood as a measure towards federalism. Britain hence negotiated an opt-out clause ( as did Denmark ) . Maastricht run into troubles ( notably, rejection in the Danish referendum ) , but despite this the Euro-bulldozer rolled inexorably frontward, traveling from aspiration to world. A European Central Bank was established in Frankfurt. And in 1999 the Euro became the national currency of the bulk of EU provinces. 3. Brown ‘s Five Trials The Debate of the Single Currency Concept The Debate of the Single Currency Concept The Debate of the Single Currency Concept In 1997 Gordon Brown, the British Chancellor, set out a series of five trials, designed to enable a determination upon the annoyed inquiry of whether Britain should fall in the Euro. These trials give a clear reply: â€Å" decidedly, possibly. â€Å" These trials are, foremost, whether there can be sustainable convergence between Britain and the economic systems of a individual currency ; secondly, whether there is sufficient flexibleness to get by with economic alteration ; thirdly, the consequence on investing ; fourthly, the impact on our fiscal services by and large ; and fifthly, whether it is good for employment. ( 1997 ) 3.1. Convergence This trial asked if the UK ‘s economic system was sufficiently convergent with the remainder of Europe ( presumptively the Chancellor remembered Black Wednesday ) . It was non met in 1997, and failed once more in 2003. As Schwartz commented: Giving up its ain pecuniary policy to be ruled by EU pecuniary policy will expose it to involve ment rate motions that are non appropriate to its economic state of affairs and can immerse it into recession. ( 2000, p.68 ) But although one can surely reason there is deficient convergence, Howell points out that: â€Å" [ I ] f the UK gives a strong signal that it wishes to fall in in a set clip frame, UK involvement rates, merely like Italy ‘s or Portugal ‘s are likely to meet towards the nucleus provinces. â€Å" ( 2002, p.31 ) 3.2. Flexibility This trial aims to analyze whether there is sufficient flexibleness to get by with economic jobs that might emerge. This trial was non met in 1997, a decision repeated in 2003. 3.3. Investing Clearly there are differing positions on the consequence of the Euro upon inward investing. However, it was held that this trial was met. 3.4. Financial Services The fiscal services industry has ever been important to the UK ‘s fiscal wellbeing, and Brown evidently felt the demand to underscore this. Again, there is conflicting grounds upon the consequence entry into the Euro would hold on the City. Ultimately though, it was held that this trial was met. 3.5. Growth, Stability and Employment Brown held that growing, stableness and employment must be considered – a trial held to be met. With merely three of the five trials met, Brown was non obliged to inquire the state its positions on the Euro ; handily for Brown, given that sentiment polls systematically show British public disfavor of the Euro. It is unsurprising, nevertheless, given that the trials are sufficiently intangible to guarantee that they can be met, or non, as political expedience demands. Brown has stated unambiguously that there will be a referendum before the Euro is adopted, stating: â€Å" [ B ] ecause of the magnitude of the decisionaˆÂ ¦ , whenever the determination to enter is taken by Government, it should be put to a referendum of the British people. † ( 1997 ) Therefore, whilst it is clear that a referendum can non be won, the authorities will claim the five trials have non been fulfilled, forestalling them from contending an unwinnable referendum. But if in the hereafter the electorate is more unfastened to the Euro, the authorities can state the trials have been met, and keep a referendum. 4.

The determination will travel to the bosom of a province ‘s sovereignty – although Brown denies this: If a individual currency would be good for British occupations, British concern and future prosperity, it is right in rule to fall in. The constitutional issue is a factor in the determination, but it is non an overruling one. Rather, it signifies that, in order for pecuniary brotherhood to be right for Britain, the economic benefit should be clear and unambiguous. [ accent added ] ( 1997 ) But these constitutional issues can non be swept off so readily. As Gamble provinces, â€Å" the economic instance by itself will ne’er be conclusive or decisive. It is the political pick that counts. â€Å" ( 2000, p.4 ) Joining the Euro is lasting. It takes off, everlastingly, one facet of a province ‘s independency. This is no little issue, a nd it should non be treated as one. Whilst a province remains outside the Eurozone, its options remain unfastened. Entry will, needfully, restrict its options. Once in it would be highly hard ( and lawfully doubtful ) to go forth. Further, there can be no uncertainty that the common currency is a move towards a federal province for, as Issing points out, a individual currency is used as a â€Å" pace-setter towards political integrationaˆÂ ¦ † ( 1996, p.20 ) This may, of class, be no bad thing. One Euro protagonist ( who, remarkably for a pro-Euro author, acknowledges its profound political impact ) suggests that fall ining the Euro would intend connection: â€Å" [ a ] societal democratic EuropeaˆÂ ¦ , a trade brotherhood EuropeaˆÂ ¦ , a citizens ‘ Europe † ( Gamble, 2000, pp.4-24 ) Ultimately, the issue of whether or non to fall in the Euro will ever be political. As Jones points out, authoritiess are political existences: â€Å" Governments reg ard the pick for pecuniary integrating from a self-interested instead than an selfless position. Their concretion is subjective instead than objective. â€Å" ( 2002, p.4 ) It is absolutely possible to supply a solid instance for fall ining the Euro. Equally, a convincing instance for staying outside the Eurozone can be made. Ultimately, the existent determination is political, non economic. It must, nevertheless, be emphasised that whether or non the United Kingdom enters the Eurozone, a pick is still being made. Inactivity is here every bit positive an act as activity. As Huhne points out: â€Å" Britain can non simply choose out and feign that nil is go oning. † ( 2001, p.96 ) There is no simple reply to this inquiry. It is a political inquiry that continues to resound in Westminster. 5. Life Outside the Euro: A Lucky Escape or an Opportunity Missed? When provinces accede to the European Union, they are explicitly accepting the full organic structure of European jurisprudence, the acquis communitaire. They are, hence, accepting that when their economic system meets the Euro ‘s demands, they will fall in the Euro. In order to make this, they will necessitate to fall in the Exchange Rate Mechanism for a two twelvemonth period, and maintain their exchange rate within the ERM ‘s bounds. After this, they will go members of the Eurozone. The diagram below explains this procedure. Integration of the AC into the pecuniary brotherhood through the ERM-II ( Krawczyk, 2004, p.3 ) Phase I Phase II ( at least two old ages ) Phase III EU accession and the ERM II rank Convergence appraisal and ( finally ) following the Euro The accession provinces do non hold an absolute timetable for fall ining the Euro zone. But in clip they will fall in it. The Euro, hence, is set to turn. In the interim, Britain and Denmark retain their â€Å" o pt-out † rights vis-a-vis the Euro, and Sweden has yet to travel to it. It should be noted that there is some concern about the accession states fall ining the Eurozone. Indeed, â€Å" Mr Koch-Weser, a Germany finance ministry functionary, has advised the future Member States that they should first beef up their economic systems. â€Å" ( 2003 ) Given that the Euro will merely spread out, what will go on to those provinces that remain outside the Eurozone? Will their currency be â€Å" relatively smallaˆÂ ¦.squeezed between the great tectonic home bases of Europe and America †? ( Huhne, 2001, p.96 ) It is alluring to presume that they will be isolated, but is this truly the instance? Once once more, this essay will concentrate upon the UK. Whilst many governments emphasise the troubles which will be faced by the UK staying outside of the Euro, others argue that the UK ‘s involvements are really best served by staying outside the Eurozone. Indeed, Ferguson a nd Kotlikoff go every bit far as to propose that the Euro might non itself survive: What matters is whether the full pecuniary brotherhood will keep together in the old ages in front. The Euro ‘s medium-term hereafter will turn out much shakier when Europe is hit by the financial crises looming for the bulk of the Euro zone ‘s member states. ( 2006, p.111 ) 6. Decision There can be no uncertainty that, as persons, we might salvage money when traveling on vacation should Britain fall in the Eurozone. But there are many jobs which will confront the Euro over the following 10 old ages – in peculiar those of enlargement, and the entry of less financially sound economic systems into the Eurozone. This leaves open the possibility that instead than enduring outside the Eurozone, the UK ‘s economic system may even surpass the European economic system. As Eddie George points out: The UK, overall, has suffered no ill-effects from maintaining the lb, while the Euro-zone economic systems have done less good than expected, and, in many respects, less good than the UK. These economic phenomena are about surely structural, non transeunt. ( 2000 ) It is possible that if Britain continues to decline to fall in the Euro we will be left chill, whilst other provinces bask in the heat of the Euro-glow. But it is every bit possible that Britain will, on the whole, turn out to be better off by declining to fall in the Euro. Ultimately, Britain may turn out to be the lone individual processing in measure.

Essay on Samms Stryo

Essay on Samms Stryo Essay on Samms Stryo Sammy: â€Å"30 Years Later† â€Å"Paper or plastic?† I said. After a while these types of questions are the ones that seem to connect you with the customer. It was a rainy Friday afternoon. Here I was, again. 30 years ago I decided to leave this dump. I thought I would be the Superman of grocery shopping. I left thinking that I had done a heroic thing. After I went home to my parents they gave me the speech of my life. I went thinking that I would be this grand person and become someone important. It’s funny how when you’re a kid you think that you can rule the world and do the unthinkable. Then, life hits you and you see that you are just another person in the world. Eventually, going back to the store helped me realize this. Pitiful and embarrassing are the words that I came back with. I’ve always wondered whether or not those girls still remember me. I mean obviously, as a teenage with raging hormones I noticed them. After thinking about that si tuation, I never again will say anything. You see whether you try to be the nice or bad guy in life you will always come out at the wrong end. So, as this Friday afternoon started coming to the end of my shift, I noticed that the rain began to pick up with a stronger force. It seemed as if someone just decided to pour out buckets of water from the sky. I mean I like the rain but this didn’t seem like the type of rain that would fall all the time. I noticed that many people from the sidewalk started running into the store. I mean I didn’t want to do anything, I was tired of it. I decided to stay where I was and help this lady. The lady had the exact type of qualities from 30 years. The type that checks whether or not you’ve scanned the item twice and right away be there to correct you. This woman wasn’t too old. My age I guess, and well she seemed pretty attractive for my age. I’m sorry to say that I don’t have anyone to say that I love. Thos e girls changed the way I felt so I decided to stay low on the whole Mr. Player attitude. I mean come on. I can dream a little right. So this lady had something about her that I liked. I mean when you’re an old man like me, they just don’t seem to notice. â€Å"Cloth†, she said, â€Å"I know I sound like such a hippy but I just like to carry my own bag. I hope that you don’t mind†. She gave me a flirty look but I acted like I just didn’t care. â€Å"Umm†¦ yeah I guess†, I said. With that, a flash of lightning appeared in the sky. â€Å"Oh my†, she said, â€Å"Do you think that if I went outside I would get wet?† I have never heard a funnier response in my life. I mean if you think about it, who asks that. The manager was coming around again. Reminded me of a panther when you don’t know where he is yet, he just seems to appear. This guy was this young 23 years old. The kind of guy that expects everyone to like him yet you hate him with a passion. He had this short stature and had enough gel in his hair to last him a month. â€Å"What are you doing? Come on†, said Edward, â€Å"Miss, is this man disturbing you?† I looked at the customer, she looked like a Frida. â€Å"Oh no! Of course not! Why don’t you have more people like this handsome. I mean hard-working man in your store!† You know how girls turn into the red scarlet color when they get either well complimented or even if they get just really embarrassed. I turned that color. I mean this brought back that nostalgic feeling of the three girls from almost 30 years ago. Edward just went away with his big long nose in the air. He acted like those people that get proved wrong yet won’t admit it. This lady seemed to be hitting on me. Hitting me with her looks and the way that she talked about me impressed me. Look, I’ll be completely honest. I am a pretty good looking guy for my age. Sure, my co-w orkers have always told me this but I seemed too modest to accept the fact that it is true. Frida was getting her cloth bag into the cart. She kept looking at the rain, then me, then the rain. I mean I knew she wanted something but then again it seemed

Accounting - Essay Example The information contained in financial reporting must be both relevant and reliable to the user – relevant data must be recent enough to be useful and be confirmed in the future as well as confirm older data, and reliable in that different users are able to use the same information to come to similar, if not the same, conclusions about the company’s economic status, and unaffected by our own concerns within the business. (36) The latter means that no one is permitted to skew information’s presentation to better our image, so that the data is dependable for any user, whether internal or external. The information in financial reporting must also be comparable to other companies in our industry – if a practice is normally used, we should use it also so that it is easier for investors to read our reports – and consistent. (37) Should an accounting practice change, it needs to be very clearly stated and if necessary, we should adjust former periods’ information so that the impact of the change is easily discerned. Consistency is a critical attribute for us to demonstrate, so that users are able to watch the trends of our company’s success without worrying that we adjust accounting practices to improve the bottom line when having difficulties, and comparability is so that users are able to compare us to our other industry members. A last feature of the above information is the ‘matching principle’ that is required by U.S. GAAP. The matching principle is a simple rule – any expenses incurred in the current period must be matched to any revenues incurred in the current period. (45) This is a component of when we recognize revenue, and has a direct impact on the balance sheet. The above information should be helpful in understanding how our accounting practices work, and why they are so important for our investors and creditors. If

Business Report - Research Paper Example Harvey Norman barely survived with impending lawsuits and losses experienced from giving out very high discounts to attract customers. The Reject Shop on the other hand posted a good increase in profits and sales in that year. The company opened 18 new stores in that year and was able to repay much of its debts (Roth, 2013). The Reject Shop can sustain a downturn in the economy because its average unit price is A$9.00 (in 2011). As of today, the unit price is A$10.04. Even if the domestic market failed, The Reject Shop would probably survive (Greenblat, 2011). In an attempt to avoid losses and survive in the industry, the Harvey Norman Holdings Limited misled their customers by false advertisements. The federal court hit the company with a $1.25 million fine. The judge ruled in favor of the Australian Competition and Consumer commission saying that the company deliberately and blatantly disregarded the truth while conducting a calculated and misleading campaign (Appliance Retailer, 2012, p.4). The Reject Shop has not been involved in such bad publicity. When the industry domestic market was low in 2012, The Reject Shop suffered some loss like all the other retail companies but did not do illegal stuff to make more money. Metrics is the first thing looked at with any investment. The Reject Shop has a return on equity of more than 40 per cent for every year in its corporate life (Greenblat, 2011). Its debt is little or none existent and it is maintaining its return on equity despite its equity growing. This means that The Reject Shop is a good investment. The return on equity combined with little or no debt signals that the company has a strong competitive advantage. Moreover, a poll showed that 90 per cent of consumers knew about The Reject Shop. This means that the market’s place strong position and the brand awareness support the return in equity. In the recent years, its equity has risen threefold while its profits have
