The Role of Labeling and Bias in the Portrayals of Acts of “Terrorism”: Media Representations of Muslims vs. Non-Muslims

Several high-profile negative events involving Muslim perpetrators have recently been covered by the media. We investigated whether the same negative actions are more likely to be labeled “terrorism” when they are committed by Muslims than when they are committed by White non-Muslims. In Experiment I (n?=?60), using a real article about a Muslim perpetrator and a modified version about a non-Muslim perpetrator, we found that participants were more likely to identify a crime as terrorism when it was perpetrated by a Muslim. The label “terrorism” also mediated the effect of Muslim identity on negative judgments of the behavior. In Experiment II (n?=?60), we replicated the results of Experiment I and clarified that the effects persisted when we used a real article about a non-Muslim perpetrator and a modified version about a Muslim perpetrator. We discuss implications for cross-group communication and representations of Muslims in the media.     

On the Creation of Acceptable Conjoint Analysis Experimental Designs

Conjoint analysis studies typically utilize orthogonal fractional factorial experimental designs to construct a set of hypothetical stimuli. Occasionally, these designs include environmentally correlated attributes that can lead to stimulus profiles that are not representative of the subject's environment. To date, no one has proposed a remedy well-grounded in statistical theory. This note presents a new methodology utilizing combinatorial optimization procedures for creating modified fractional factorial designs that are as “orthogonal” as possible, which do not contain nonrepresentative stimulus profiles.

Examining the use of tobacco on college campuses.

The authors used the Health Risk Behavior Survey for University Students to assess the prevalence of tobacco use among undergraduates in the Florida state university system. They examined the relationships of gender, marital situation, and minority status to 6 smoking behaviors (tried cigarettes, smoked regularly, tried to quit smoking, age when first smoked regularly, number of cigarettes smoked in the last month, and number of days smoked in the past month). Findings suggested that White students were more likely than minority students to try cigarettes and women more likely than men to smoke regularly. Married students smoked more regularly than others and were less likely than single students to have tried to quit smoking. The investigators suggested analyzing latent behaviors associated with smoking and called for a national meta-analysis of data from smoking studies to help clinicians deal with student tobacco use.     

Sampling techniques and the use of Tang's procedure in insect population dynamics studies

Summary Some calculations were performed usingTang's method as an aid in planning experiments for studying the population dynamics of the Jeffrey pine beetle. The population dynamics studies were aimed at detecting the importance of specific effects, e. g., tree diameter, tree height. TheTang procedure is a method of estimating the sample size required to detect effects of a given magnitude with analysis of variance tests. Using this procedure some sample calculations were performed which indicated the sample size needed, and the efficacy of different strategies of improving the results, e. g., increasing the number of trees sampled versus increasing the area of the tree sampled. The statistical parameters used in the calculations were estimated from some preliminary sampling data. Use of this procedure is recommended in insect population studies as a method of optimally planning experiments, and as a method of making precise conclusions about the significance of specific effects. This study was supported by Contracts 68-03-0273 and 68-03-2442 with the U. S. Environmental Protection Agency, Corvallis Environmental Research Laboratory, Corvallis, Oregon.

Congregational Political Activity and Same‐Sex Marriage: Social Movement Theory and Evidence for Contextual Influence

We interpret three strands of social movement theory (social threat, opportunity structure, and resource mobilization) to understand religious congregations' political activity related to same‐sex marriage. Using a unique, national data set from the 2008 presidential election, we show the importance of the anti‐same‐sex marriage discursive opportunity structure (DOS) for facilitating, and occasionally constraining, congregational political activity. Other theoretical factors influence congregations under limited, although important, conditions. Our research develops a nuanced understanding of congregations' roles in social movements that prioritize institutionalized political activity and expands DOS theory in relation to local religious organizations.     

QUADRATIC PREFERENCES AND GOAL PROGRAMMING

One of the shortcomings of goal programming lies in its linearity, assumption, specifically in the objective function. This assumption compels one to work with constant marginal utilities and rates of substitution. In this paper a quadratic preference function, which is more consistent with economic theory and reality, is formulated and introduced into goal programming. In an effort to facilitate the understanding of the proposed procedure, two illustrative examples—one with symmetric preferences and the other with asymmetric preferences, both applied to the objective function—are solved and compared with a goal programming solution.
