The formula for the reaction is: HCl(aq) + Na2S2O3(aq) NaCl(aq) + SO2(g) + S(s) + H2O(l). The formula shows us that the sulphur precipitate is formed along with water, sodium chloride and sulphur dioxide. Sulphur dioxide is a poisonous gas and so extra care will be taken not to inhale any. Figure 1 [18] Variables The Variables that affect the reaction rate of sodium thiosulfate...

...OUTLIER’S REACTION PAPER The book „Outliers‟ is basically are success stories wherein Malcolm Gladwell, a renowned writer, gives practical explanations of how extraordinary people gain success. The stories situated in the book always involve different aspects of success such as the environment, patience and hard work, coincidences and other things happening around. Basically, the ideas give „common-sense‟ answer to the question. These people have succeeded because of the things that surrounds them and not just only by themselves. As stated “It makes a difference where and when we grew up”, this clearly explains that a person don‟t achieve success not only by himself but it matters on the situations and opportunities that lies around him. Gladwell investigates place, time and culture of these success stories in order to come up with practical explanations behind it. This also includes the relevant events that happened in certain period of time where these people are part and been to these events. So in other words, these people have been to certain event in their lives that made them succeed. Gladwell thought of these idea to see the logic about being successful or not, in this case is by asking where these people came from. One way Gladwell explains it is by determining the important events in certain period of time which are based on patterns of birthdates of a group of people such as the Canadian hockey team, Czechoslovakian National Junior Soccer team and the people behind...

...Barber, Sean 9/14/11 BIO 3314 – 101 Reaction Paper I: Rapid Range Shifts of Species Associated with High Levels of Climate Warming The article discussed how due to climate change the distributions of much of the worlds terrestrial organisms were moving in latitude or elevation. Two analysis were included in the article. One was a meta-analysis of available research of the elevation and latitudinal range shifts for different taxonomic groups. The other was based only on latitudinal shifts of species within four exemplar taxonomic groups. These studies help to show how variation within taxonomic groups is so great that more data is required to show specific prognoses for individual species. In the latitudinal part of the first analysis it was observed that species moved away from the equator at a median rate of 16.9 km per decade. In elevation that shift occurred at a median rate of 11 m uphill per decade. The study was then compared to a previous meta-analysis that examined individual species. It concluded that ranges had shifted to higher elevations at 6.1 m per decade and to higher latitudes at 6.1 km per decade. The former meta-analysis's mean rates ended up being three times higher for latitude and two times higher for elevation. It is interesting to note that both mollusks and mammals were outliers in this data. This difference could have been caused by the fact that most of the data was taken from tropical mountains and the temperate zone an these ecosystems...

...What Explains the Stock Market’s Reaction to Federal Reserve Policy? Ben S. Bernanke Kenneth N. Kuttner∗ February 7, 2003 Abstract This paper analyzes the impact of unanticipated changes in the Federal funds target on equity prices, with the aim of both estimating the size of the typical reaction, and understanding the reasons for the market’s response. On average over the May 1989 to December 2001 sample, a “typical” unanticipated 25 basis point rate cut has been associated with a 1.3 percent increase in the S&P 500 composite index. The estimated response varies considerably across industries, with the greatest sensitivity observed in cyclical industries like construction, and the smallest in mining and utilities. Very little of the market’s reaction can be attributed to policy’s effects on the real rate of interest or future dividends, however. Instead, most of the response of the current excess return on equities can be traced to policy’s impact on expected future excess returns. JEL codes: E44, G12. 1 Introduction The reaction of the stock market to monetary policy is clearly a topic of intense interest both to market participants and policymakers. Those holding equities would obviously like to know how possible Federal Reserve actions might affect the value of their portfolios. Similarly, an estimate of the likely effect of policy on asset prices is an important ingredient in assessing the transmission of monetary policy through the “wealth effect.” The size of and ...

...Timothy Pratt Wednesday, 12:20 PBIO 1210L Scientific Paper: Effect of Water Temperature on Amylase Using Colorimetric Starch Assay Introduction For plants to function properly, chemical reactions must take place within the cells of each individual plant. Energy is necessary for each reaction to occur. The amount of energy that is necessary for a reaction is called the activation energy. Enzymes are used to reach the correct activation energy in plants. They lower the activation energy to the correct amount for the reaction to take place. Certain enzymes catalyze certain reactions, which means that many enzymes to operate the cell. On each cell, there is a spot where the substrate will attach to the enzyme (active site). When the substrate and the enzyme come in contact with each other, it creates an enzyme-substrate complex. The enzyme and substrate then connect. This connection causes the pace of the reaction to speed up, causing a chemical reaction. Once the reaction has taken place, the enzyme is released out so it can perform more reactions with more substrates. Without enzymes, a cells metabolism would not be fast enough for the organism to function in the correct manner. This is evident when pertaining to the enzyme, amylase, which is found in corn. Amylase is in a group of enzymes that catalyze the hydrolysis of starch into smaller carbohydrate molecules, such as maltose. It is the also the digestive enzyme needed to digest carbohydrates. Corn is an important...

...according to the identified structural model. In order to test the defined structural model and research hypotheses empirical research was conducted on the sample of undergraduate students of the Faculty of Economics and Business in Zagreb. Research results indicate that the structural model has an acceptable level of fit to the empirical data. The estimated structural coefficients and indirect effect coefficients indicate the direction and intensity of effects of each analysed element of marketing mix on brand equity. Finally, implications of research results for the theory and practice of brand management are analysed and discussed. Keywords: brand equity, brand, strategic brand management, marketing mix JEL classification: M31 * This paper was originally published in Privredna kretanja i eknomska politika (Economic Trends and Economic Policy) No. 102, 2005, pp. 30-59. ** Edo Rajh, Research Associate, The Institute of Economics, Zagreb. Croatian Economic Survey 2005 53 1 Introduction The concept of brand equity was first introduced in marketing literature in the 1980’s. During the 90’s this topic received significant attention from both scientists and marketing practice, which resulted in a large number of articles and books on the subject (e.g. Aaker and Keller, 1990; Aaker, 1991; Keller and Aaker, 1992; Aaker and Biel, 1993; Keller, 1993; Aaker, 1996; Agarwal and Rao, 1996; Kapferer, 1998; Keller, 1998). The interest in brand equity is still active (e.g. Yoo et al.,...

...react, the reaction typically does not go to completion. Rather, the system goes to an intermediate state in which the rates of the forward and reverse reactions are equal. Such a system is said to be in chemical equilibrium. When equilibrium is reached, the reactants and the products have concentrations which do not change with time. When in equilibrium at a particular temperature, a reaction mixture obeys the Law of Chemical Equilibrium, which imposes a condition on the concentrations of reactants and products. This condition is expressed in the equilibrium constant Kc for the reaction. In this experiment, I will study the equilibrium properties of the reaction between ethanoic acid, otherwise known as acetic acid (CH3COOH) and water (H2O): CH3COOH(aq) + H2O(l) CH3COO-(aq) + H3O+(aq) When solutions containing ethanoic acid and water are mixed, they react to some extent, forming CH3COO- and H3O+. As a result of the reaction, the equilibrium amounts of CH3COOH and H2O will be less; for every mole of CH3COO- formed, one mole of CH3COOH and one mole of H2O will react. The equilibrium constant expression Kc for Reaction 1 is: Kc = [CH3COOH] / [H3O+][CH3COO-] The value of Kc is relatively constant at a given temperature. This means that mixtures containing CH3COOH and H2O will come to equilibrium with the same value of Kc, no matter what initial amounts of CH3COOH and H2O were used. The purpose of this experiment will be to find Kc for this reaction for several...

The first independent variable in this experiment is the luminance patches which consists of three levels, light condition, dark condition and equiluminance condition, and the second independent variable is the location of the target which consists of two levels, same side (valid) or opposite side (invalid). 2. The first limitation in the experiment is that the sample size is too small and there needs to be more participants in the experiment to have an accurate representation of the general population. Another limitation in the experimental design is that the participants are not randomly...

...population or a research area of interest.” (Week 3 Podcast) In this paper we are going to discuss the different ways of collecting data, as well as how reliability and validity play a part in the research methods of criminal justice. We will also discuss the advantages and disadvantages of certain survey distribution techniques, and how reliability and validity are important. Also in this paper, I will show you the importance of a police officer and their role in collecting data. There are many different ways that data is collected in the criminal justice system. Examples of these are with surveys and questionnaires, and Sampling. These are used to gather information about the area and the people in it. Surveys are made with premade responses to the questions asked. Questionnaires are made with open ended questions. “Questionnaire development is made of a series of steps. The first step would be deciding what information you are trying to receive, identify the participants taking the survey, selecting the methods of reaching the participants, question development. There are many advantages and disadvantages when it comes to the different forms of surveys. There are in Person, Telephone, Computer-Based, and Focus Group Surveys; just to name a few types. In person surveys are like interviews. You meet face to face and are asked many different questions. The advantages to in person surveys are that you can see the reactions to the questions better, and that you can see if they are lying...

...A C C O U N T I N G & A U standards setting D I T I N G Disclosure of the Engagement Partner in the Audit Report An International Perspective on the PCAOB Proposal By Jason Bergner and Ling Lin n December 4, 2013, the PCAOB conducted an open meeting to reconsider its proposal to require the disclosure of the engagement partner (and certain other participants) in the audit report, as part of its efforts to improve transparency. The PCAOB is carefully considering the likely costs and benefits of this requirement before making a final decision (http://pcaobus.org/News/Speech/Pages/120 42013_Harris_Transparency.aspx). The authors present arguments for and against requiring audit partner disclosure and summarize the current practice and empirical findings in foreign jurisdictions, such as the EU and China. While the debate for the past five years has been an argument about the possible costs and benefits of a signature or disclosure requirement, the authors believe that the movement of the international community toward adopting common standards may eventually warrant a similar U.S. approach. O Debating the Issue The signature/disclosure requirement has been an issue for almost a decade, first appearing on the PCAOB’s agenda in 2005 (Tammy Whitehouse, “Divided PCAOB Presses for Names in Audit Report,” December 4, 2013, Compliance Week, http://www.complianceweek.com/dividedpcaob-presses-for-names-in-audit-report/article/323604/).

...Kazzy Zeh-Arndt Mr. Patrick Walker English 4 Honors 19 November 2014 Senior Paper The United State’s mishandling of serious events has caused American satisfaction with the government to decline ever since the end of World War 2. Shortly after World War 2, the American people were in full support of the government. Franklin Roosevelt had pulled the country out of the biggest economic depression it had ever seen and has seen since, as well as winning World War 2. World War 2 was a clear cut war in terms of who was in the wrong and who was the in the right, the holocaust and the German aggression in Europe were obviously amoral acts that needed to be stopped. Winning WW2 was almost as instrumental as getting out of the depression for the government...

...Reaction Paper Regarding the Flow of Influence and Social Meaning Across Social Media Networks Mahalia Miller Daniel Wiesenthal October 6, 2010 1 Introduction One topic of current interest is how language and sentiments are transmitted in the blogosphere and how individuals affect the sentiments of those in their online sphere of influence. Therefore, the focus of this reaction paper is threefold: (1) to summarize four journal papers related to sentiments and influence, (2) to critique the methods and scope of the journal papers and (3) to brainstorm directions for the term project. 2 2.1 Literature review Java et al. 2006 Java et al. (2006) explore models that determine the blogs with the most influence on the Blogosphere. The paper defines influence as a link from blog a to blog b implies that a influences blog b. They further create an influence graph that weights edges by a function of the amount of links. This paper evaluates various heuristics, such as Pagerank, indegree, and greedy algorithm, to determine which blogs have the most influence on the Blogosphere. The analysis shows that PageRank is rather efficient and converges quickly. The paper also analyzes the effect of splogs, i.e. spam blogs. The results indicate that not removing splogs greatly impacts the accuracy of the influence models. As such, the paper uses some algorithms to identify splogs, and then, and only then, do the heuristics converge to within 70% agreement on the predicted number of influenced...

...on macroeconomic activity generated symmetric movement between price and many macroeconomic indices in the 1970's. However, after 1982, macroeconomic indices did not demonstrate the same proclivity to react to oil price movement. Information spreads almost instantly with the emergence of the internet. This expedient movement of news has led to an evolving trend of speculation which may or may not be beneficial to commodity pricing. One may infer that the recent prevalence of mass media leads to rapid movement back and forth of oil prices. I insert this topic at this point to bring to the surface that mass media was in early development during the proposed study periods. The research on oil price fluctuation has produced varying reactions among academia and policy makers. Impressions about the impact of oil price fluctuation and the resulting effect...

We find that diversifying bank acquisitions earn significantly negative announcement period abnormal returns (AR) for bidder banks whereas focusing acquisitions earn zero AR. We then find that corporate governance variables (such as CEO share and option ownership and a smaller board size) in the bidding bank are less effective in diversifying acquisitions than in focusing acquisitions. These results are robust to the inclusion of the usual control variables. Ó 2002 Elsevier Science B.V. All rights reserved.
