Africa In The World Trade Network, Luca De Benedictis Aug 2010

Africa In The World Trade Network, Luca De Benedictis

Luca De Benedictis

This paper contributes to the analysis of the effect of the global financial crisis (Claessens et al., 2010) on African coutries (IMF, 2009) inspecting the effect of the crises on bilateral trade flows. The empirical analysis makes intensive use of network analysis techniques, describing the international trade of SSA countries as part of the world trade network. The paper analyzes the change in the topology of the trade network during the crisis. Single SSA countries participation to the network is reported in terms of link strength and centrality, showing if some specific countries were more radically disconnected from the giant …

An Essay On The Nature And Significance Of Deception And Telling Lies, Sudhanshu K. Mishra May 2010

An Essay On The Nature And Significance Of Deception And Telling Lies, Sudhanshu K. Mishra

Sudhanshu K Mishra

A lie is an expression at deviance with the truth known or honestly believed by someone with an intention to deceive others for certain purpose, social or personal. An ability to lie might be evolutionary in nature possibly to help in survival, since it is found in the non-human world also. In the biological perspective, each individual is at war against all others. Thus viewed, lies are the cardinal virtues for survival and, by implication, the carriers of evolution. In the human world, lying is morally blameworthy in a relatively un-obscure way. There may be cases of lying to which …


The 1905 Einstein Equation In A General Mathematical Analysis Model Of Quasars, Byron E. Bell May 2010

The 1905 Einstein Equation In A General Mathematical Analysis Model Of Quasars, Byron E. Bell

Byron E. Bell

The 1905 wave equation of Albert Einstein is a model that can be used in many areas, such as physics, applied mathematics, statistics, quantum chaos and financial mathematics, etc. I will give a proof from the equation of A. Einstein’s paper “Zur Elektrodynamik bewegter Körper” it will be done by removing the variable time (t) and the constant (c) the speed of light from the above equation and look at the factors that affect the model in a real analysis framework. Testing the model with SDSS-DR5 Quasar Catalog (Schneider +, 2007). Keywords: direction cosine, apparent magnitudes of optical light; ultraviolet …


Reducing The Impact Of Ethnic Tensions On Economic Growth – Economic Or Political Institutions?, Atin Basu Choudhary, Jim Bang, Michael Reksulak May 2010

Reducing The Impact Of Ethnic Tensions On Economic Growth – Economic Or Political Institutions?, Atin Basu Choudhary, Jim Bang, Michael Reksulak

Atin Basu Choudhary

We use a standard growth regression model and show that ethnic tensions reduce per capita growth rates. We also find evidence that “good” economic and political institutions improve per capita growth rates. More importantly, good economic institutions mitigate the effect of ethnic tensions on per capita growth while good political institutions do not. Consequently, it is foremost capitalist freedom that promotes peace and development.


Big Macs And Eigenfactor Scores: Don't Let The Correlation Coefficients Fool You, Jevin D. West, Carl T. Bergstrom, Theodore C. Bergstrom Apr 2010

Big Macs And Eigenfactor Scores: Don't Let The Correlation Coefficients Fool You, Jevin D. West, Carl T. Bergstrom, Theodore C. Bergstrom

Ted C Bergstrom

A recent article by Phil Davis suggested that the Eigenvalue metric does adds little useful information to the more simply calculated measure of total citations published by the ISI. This paper argues that Davis's claim is an instance of a classic statistical fallacy of spurious correlation. Based on an analysis of the entire 2006 ISI Journal Citation Reports, we show that there are statistically and economically significant differences between the Eigenfactor metrics and the ISI's impact factor and total citations.

Temporal Changes In The Parameters Of Statistical Distribution Of Journal Impact Factor, Sudhanshu K. Mishra Mar 2010

Temporal Changes In The Parameters Of Statistical Distribution Of Journal Impact Factor, Sudhanshu K. Mishra

Sudhanshu K Mishra

Statistical distribution of Journal Impact Factor (JIF) is characteristically asymmetric and non-mesokurtic. Even the distribution of log10(JIF) exhibits conspicuous skewness and non-mesokurticity. In this paper we estimate the parameters of Johnson SU distribution fitting to the log10(JIF) data for 10 years, 1999 through 2008, and study the temporal variations in those estimated parameters. We also study ‘over-the-samples stability’ in the estimated parameters for each year by the method of re-sampling close to bootstrapping. It has been found that log10(JIF) is Pearson-IV distributed. Johnson SU distribution fits very well to the data and yields parameters stable over the samples. We conclude …


Empirical Probability Distribution Of Journal Impact Factor And Over-The-Samples Stability In Its Estimated Parameters, Sudhanshu K. Mishra Feb 2010

Empirical Probability Distribution Of Journal Impact Factor And Over-The-Samples Stability In Its Estimated Parameters, Sudhanshu K. Mishra

Sudhanshu K Mishra

The data on JIFs provided by Thomson Scientific can only be considered as a sample since they do not cover the entire universe of those documents that cite an intellectual output (paper, article, etc) or are cited by others. Then, questions arise if the empirical distribution (best fit to the JIF data for any particular year) really represents the true or universal distribution, are its estimated parameters stable over the samples and do they have some scientific interpretation? It may be noted that if the estimated parameters do not exhibit stability over the samples (while the sample size is large …


A Note On Empirical Sample Distribution Of Journal Impact Factors In Major Discipline Groups, Sudhanshu K. Mishra Feb 2010

A Note On Empirical Sample Distribution Of Journal Impact Factors In Major Discipline Groups, Sudhanshu K. Mishra

Sudhanshu K Mishra

What type of statistical distribution do the Journal Impact Factors follow? In the past, researchers have hypothesized various types of statistical distributions underlying the generation mechanism of journal impact factors. These are: lognormal, normal, approximately normal, Weibull, negative exponential, combination of exponentials, Poisson, Generalized inverse Gaussian-Poisson, negative binomial, generalized Waring, gamma, etc. It is pertinent to note that the major characteristics of JIF data lay in the asymmetry and non-mesokurticity. The present study, frequently encounters Burr-XII, inverse Burr-III (Dagum), Johnson SU, and a few other distributions closely related to Burr distributions to best fit the JIF data in subject groups …


Responding To Stakeholders’ Critical Needs- The Integrative Model Of Stakeholders’ Management (Imsm), Grace S. Thomson Jan 2010

Responding To Stakeholders’ Critical Needs- The Integrative Model Of Stakeholders’ Management (Imsm), Grace S. Thomson

Dr. Grace S. Thomson

Organizations are increasingly required to enhance their accountability to diverse internal and external stakeholders (Burrows, 1999). Knowing and understanding stakeholders’ expectations increases the ability of an organization to effectively respond to those expectations. Stakeholder relationship management is critical for corporate sustainability (Perrini & Tencati, 2006) or “capacity of a firm to continue operating over a long period of time” (p. 296). Organizations may benefit from developing collaborative interactions with their stakeholders, integrating their values and views into the formulation and implementation of organizational goals and objectives (Merrick, Parnell, Barnett & Garcia, 2005; Susniene & Vanagas, 2006).

This document contains a …

Participation And Engagement In Sport: A Double Hurdle Approach For The United Kingdom, Babatunde Buraimo, Brad Humphreys, Rob Simmons Jan 2010

Participation And Engagement In Sport: A Double Hurdle Approach For The United Kingdom, Babatunde Buraimo, Brad Humphreys, Rob Simmons

Dr Babatunde Buraimo

This paper uses pooled cross-section data from four waves of the United Kingdom’s Taking Part Survey, 2005 to 2009, in order to investigate determinants of probability of participation and levels of engagement in sports. The two rival modelling approaches considered here are the double-hurdle approach and the Heckman sample selection model. The Heckman model proves to be deficient in several key respects. The double-hurdle approach offers more reliable estimates than the Heckman sample selection model, at least for this particular survey. The distinction is more than just statistical nuance as there are substantive differences in qualitative results from the two …


Mitigation And The Geoengineering Threat, Juan B. Moreno-Cruz Jan 2010

Mitigation And The Geoengineering Threat, Juan B. Moreno-Cruz

Juan B. Moreno-Cruz

Recent scientific advances have introduced the possibility of engineering the climate system to lower ambient temperatures without lowering greenhouse gas concentrations. This possibility has created an intense debate given the ethical, moral and scientific questions it raises. In this paper I examine the economic issues introduced when geoengineering becomes available in a standard two-period two-country model where strategic interaction leads to suboptimal mitigation. Geoengineering introduces the possibility of technical substitution away from mitigation, but it also affects the strategic interaction across countries: mitigation decisions made in the first period directly affect the geoengineering decisions made in the second period. With …
