AN EXPERIMENTAL COMPARISON OF STATISTICAL AND LINEAR PROGRAMMING APPROACHES TO THE DISCRIMINANT PROBLEM

This paper reports the results of an experimental comparison of three linear programming approaches and the Fisher procedure for the discriminant problem. The linear programming approaches include two formulations proposed by Freed and Glover and a newly proposed mixed-integer, linear goal programming formulation. Ten test problems were generated for each of the 36 cells in the three-factor, full-factorial experimental design. Each test problem consisted of a 30-case estimation sample and a 1,000-case holdout sample. Experimental results indicate that each of the four approaches was statistically preferable in certain cells of the experimental design. Sample-based rules are suggested for selecting an approach based on Hotelling's T² and Box's M statistics. Subject Areas: Statistical Techniques, Linear Statistical Models, and Linear Programming.     

The Inadequacy of Mainstream Theories ofTrade Union Behaviour

This paper identifies four criteria used by mainstream economists of trade unions to judge the adequacy of their various theories. Three of them, however, are hardly ever satisfied. The root cause of this failure is the method adopted by mainstream economic theory, namely deductivism. The perspective of critical realism is used to identify and explain the cause of this failure and to point towards an alternative method.     

The Undeserving Rich: “Moral Values” and the White Working Class1

White working‐class citizens who vote for the Republican Party have been fodder for much political discussion and speculation recently, and a debate has arisen about the role that “moral values” played in the political decision making of this segment of voters. In this article, we defend a version of the moral values claim. We show that although the Republicans’ policies are unpopular, they are bundled with an overarching moral framework that is extremely resonant to this set of voters, and we use in‐depth interviews to uncover this framework. A key feature of this framework, on which in the 2004 presidential election George W. Bush scored high and John Kerry scored low, is the appropriate attitude to wealth, which serves as an indicator for a candidate’s general moral philosophy and as a heuristic about whether the candidate will govern with working‐class voters’ interests in mind. National Election Studies data support the argument that this was a key influence on the voting decision in 2004, even controlling for voters’ partisan identification.     

"There Must Be a Reason": Osama, Saddam, and Inferred Justification

One of the most curious aspects of the 2004 presidential election was the strength and resilience of the belief among many Americans that Saddam Hussein was linked to the terrorist attacks of September 11. Scholars have suggested that this belief was the result of a campaign of false information and innuendo from the Bush administration. We call this the information environment explanation. Using a technique of "challenge interviews" on a sample of voters who reported believing in a link between Saddam and 9/11, we propose instead a social psychological explanation for the belief in this link. We identify a number of social psychological mechanisms voters use to maintain false beliefs in the face of disconfirming information, and we show that for a subset of voters the main reason to believe in the link was that it made sense of the administration's decision to go to war against Iraq. We call this inferred justification : for these voters, the fact of the war led to a search for a justification for it, which led them to infer the existence of ties between Iraq and 9/11.     

The School-Based Family: Teachers as Parental Figures for Orphans and Vulnerable Children in Ugandan Schools

The purpose of this study was to examine the possible formation of surrogate families within Ugandan schools, especially among orphans who lack positive development opportunities typically provided by parents. This qualitative study sample of 66 Ugandan secondary school students were selected from eight schools in the Mukono district of Uganda. Findings suggest a potentially widespread family formation pattern between students and their teachers. More than 75% of students interviewed self-identified their teacher as family. Some teachers were able to offer orphans and vulnerable children positive developmental assets and were, therefore, identified as family.     

(Unintended) Consequences of initiating an alcohol sales policy at college football stadiums: A case study

University officials are increasingly considering selling alcoholic beverages at campus football stadiums. To inform this decision, we report on offenses occurring at a campus football stadium and surrounding community on game day weekends between 2009 and 2013. Campus police log data for 35 home football weekends were examined, accounting for 1,940 distinct incidents. There was a general upward trend in crime incidents. On average, 330 total crime incidents occurred when alcohol was not sold (2009–2011) compared to 475 annually when alcohol was sold (2012–2013). Liquor law violations and alcohol consumption by a minor were the two most frequently cited offenses. Liquor law violations (317) was highest after alcohol sales initiated. Police incidents were markedly higher when playing a traditional football rival at home. College administrators, health officials, athletic departments, and local law enforcement must work together to weigh the potential benefit of enhanced financial profit against the risk of increased alcohol-related crime.
