...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...

...Opinion Mining Using Econometrics: A Case Study on Reputation Systems Anindya Ghose Panagiotis G. Ipeirotis Arun Sundararajan Department of Information, Operations, and Management Sciences Leonard N. Stern School of Business, New York University {aghose,panos,arun}@stern.nyu.edu Abstract Deriving the polarity and strength of opinions is an important research topic, attracting significant attention over the last few years. In this work, to measure the strength and polarity of an opinion, we consider the economic context in which the opinion is evaluated, instead of using human annotators or linguistic resources. We rely on the fact that text in on-line systems influences the behavior of humans and this effect can be observed using some easy-to-measure economic variables, such as revenues or product prices. By reversing the logic, we infer the semantic orientation and strength of an opinion by tracing the changes in the associated economic variable. In effect, we use econometrics to identify the “economic value of text” and assign a “dollar value” to each opinion phrase, measuring sentiment effectively and without the need for manual labeling. We argue that by interpreting opinions using econometrics, we have the first objective, quantifiable, and contextsensitive evaluation of opinions. We make the discussion concrete by presenting results on the reputation system of Amazon.com. We show that user feedback affects the pricing power of merchants and by measuring their pricing...

...Schriften, 58-82. 1946 Triebe Und Triebschicksale G.W., 10, 210-232. (b) English Translation: 1925 ‘Instincts and their Vicissitudes’ C.P., 4, 69-83. (Tr. C. M. Baines.) The present translation, though based on that of 1925, has been very largely rewritten. Freud began writing this paper on March 15, 1915; it and the following one (‘Repression’) had been completed by April 4. It should be remarked by way of preface that here (and throughout the Standard Edition) the English word ‘instinct’ stands for the German ‘Trieb’. The choice of this English equivalent rather than such possible alternatives as ‘drive’ or ‘urge’ is discussed in the General Preface to the first volume of the edition. The word ‘instinct’ is in any case not used here in the sense which seems at the moment to be the most current among biologists.1 But Freud shows in the course of this paper the meaning which he attaches to the word so translated. Incidentally, on p. 195 below, in the paper on ‘The Unconscious’, he himself uses the German word ‘Instinkt’, though possibly in a rather different sense. There is, however, an ambiguity in Freud's use of the term ‘Trieb’ (‘instinct’) and ‘Triebrepräsentanz’ (‘instinctual representative’) to which, for the sake of clearer understanding, ————————————— 1...

...The Nonsynonymous/Synonymous Substitution Rate Ratio versus the Radical/ Conservative Replacement Rate Ratio in the Evolution of Mammalian Genes Kousuke Hanada,* Shin-Han Shiu, and Wen-Hsiung Li* *Department of Ecology and Evolution, University of Chicago; and Department of Plant Biology, Michigan State University There are 2 ways to infer selection pressures in the evolution of protein-coding genes, the nonsynonymous and synonymous substitution rate ratio (KA/KS) and the radical and conservative amino acid replacement rate ratio (KR/KC). Because the KR/KC ratio depends on the definition of radical and conservative changes in the classification of amino acids, we develop an amino acid classification that maximizes the correlation between KA/KS and KR/KC. An analysis of 3,375 orthologous gene groups among 5 mammalian species shows that our classification gives a significantly higher correlation coefficient between the 2 ratios than those of existing classifications. However, there are many orthologous gene groups with a low KA/KS but a high KR/KC ratio. Examining the functions of these genes, we found an overrepresentation of functional categories related to development. To determine if the overrepresentation is stage specific, we examined the expression patterns of these genes at different developmental stages of the mouse. Interestingly, these genes are highly expressed in the early middle stage of development (blastocyst to amnion). It is commonly thought that developmental genes...

...3. Results and discussion 3.1. Preparation conditions of molecularly imprinted polymer The preparation process of MIP is quite simple, but a number of factors which affect the polymerization and imprinted effect have to be taken to account. For the synthesis of the MIP, MAA was chosen as the functional monomer because, from the previous experience, this is the best functional monomer in order to establish selective hydrogen bonding interactions with the functional groups of bentazon. Another important parameter that affected the capability of MIP synthesized in the synthesis process is molar ratio of template/monomer/cross-linker. Only appropriate molar ratio of template/monomer can afford high selectivity with MIP. And the amount of cross-linker should be high enough to maintain the stability of the recognition sites (Andersson et al, 1999). Through complex optimization experiments, the MIP...

...works based on the difference in solubility when the temperature changes. Therefore, picking the solvent to dissolve the compound is a very tricky and important part. For single-solvent recrystallization, which is performed in this experiment, the chosen solvent should not dissolve the sample while cold, so that the crystal can be formed when the temperature drops. However, the solvent should dissolve the sample completely while hot in order to release all the impurity crystals being trapped up in the solid form of the desired compound. Furthermore, the impurities should have higher solubility than the desired compound in that chosen solvent, so that all the impurities would remain in the solution while recrystallization takes place.2,3 In case no single solvent can be found, a system of two solvents can also be used for recrystallization. Generally speaking, in this solvent pair, one of them can completely dissolve the sample while the other one cannot dissolve the sample at all. The primary requirement when making this system is that the two chosen solvents have to be completely miscible, in other words, can mix with each other in all proportions. After this requirement is satisfied, all students need to do is to find out the right proportion for the system.1,2,3...

...E663 Laboratory session 8: AC Operational Amplifiers Agrim Ganti University College London 5th December 2008 ABSTRACT The report is written on an investigation which comprises of testing three operational amplifier circuits with AC signals. The three types of circuit include the integrator, the AC inverting amplifier and the AC non-inverting amplifier circuit. The integrator circuit was tested with a square-wave and a sinusoidal wave input signal at 1kHz frequency. The results showed that the square-wave input signal produced a triangular wave output whereas the sinusoidal input produced a sinusoidal output signal with a positive 90 degree phase shift. Both output signals were showed to be the integral of their relative input signals. The output voltage gain of the AC inverting and the AC non-inverting amplifier circuits were tested with a frequency range of 100Hz to 10kHz. The results were plotted on a logarithmic scaled graph which showed that both amplifiers acted like high-pass filters, each amplifier achieving its maximum gain set by the specification at higher frequencies nearer to 10kHz. The only difference between the two op-amps was that the AC inverting amplifier achieved negative gain in comparison to the positive gain achieved by the AC non-inverting amplifier. For further investigation, the frequency was increased above 10kHz for the AC inverting amplifier circuit which showed a linear fall in gain, which was explained by the theory of slew rate limitation...

...ORGANIZATIONAL BEHAVIOUR Case study- 6 All the Wrong Moves Outline of the case A. Introduction Nutrorim was established in 1986 by an organic farmer and his wife. Don Rifkin had taken the charge of CEO in 1989. Its products were gaining national attention. The sales of organic performance enhancing supplement powder ChargeUp, was increasing enormously. It was the best selling product among the category. ChargeUp has undergone an upgrade with the additive Lipitrene. The new ChargeUp has just been released on a limited basis to local area retailers. Company’s expectation with this upgraded product was high. With the end of first quarter, the sales had been increased by 20% in the test market. Don has a way of trying to avoid conflict. When ChargeUp was in the marketing phase, the marketing manager asked the opinion of the entrepreneur Nora. Nora was not keen on the product with the new ingredient. This caused friction between her and the R&D manager Steve. That time Don had tried to restore the peace. But before the state wide launch, an investigator from a state department of health had informed Don that he was investigating 11 individuals from Syd’s Gym who took ChargeUp, who now had gastrointestinal distress. He advised him to recall the product from the market. Don called an emergency meeting with heads of PR, Sales, R&D, and Legal to decide whether to recall the product. CEO Rifkin had always tried to provide an open and democratic environment for...

...CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds, in which the sharing of the electron pair is unequal, with the electrons spending more time around the more non-metallic atom, are called polar covalent bonds. In such a bond there is a charge separation with one atom being slightly more positive and the other more negative, i.e., the bond will produce a dipole moment. On the other hand, Ionic bonds are bonds in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other. In the extreme case where one or more atoms lose electrons and other atoms gain them in order to produce a noble gas electron configuration, the bond is called an ionic bond. Covalent bonding is a form of chemical bonding between two non-metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds. Ionic bond, also known as electrovalent bond is a type of bond formed from the electrostatic attraction between oppositely charged...

...most influential. According to psychology, a major part of other people's perception about a person is determined by these two dimensions of personality (Cuddy, Kohut and Neffinger, 2013, p. 56). The dilemma of the choice between these two is inherently present in the nature of the two extremes i.e. either of the choices will make you fall at the opposing ends of the human emotional spectrum. It is interesting to note that the question of choosing between the two extremes is not a new one . Tracing this conundrum back to the sixteenth century takes us to the writings of Machiavelli. His political philosophy in 'The Prince' acknowledges the best leaders to command both fear and love. Having said that, Machiavelli recognizes the opposite polarity of the two emotions and maintains that since it is difficult to combine both in one person, it is better to be feared as a leader than to be loved (Machiavelli, 2003, p.53). Today, about five hundred years later, the Machiavellian concept of a feared leader is still quite rigorously followed by leaders in fields including business. The issue that crops up here is the overemphasis on soft emotions like love in almost every facet of life as opposed to the use of fear when it comes to leadership. If humans are managed better through fear, what is the place of emotions like love, empathy and compassion in organizational dynamics and leadership? Another aspect that relates to this...
