Voter preferences,simple electoral games,and equilibria in two-candidate contests

The fundamental assumption of spatial models of party competition is that voters possess cardinal utility functions defined on all combinations of issue positions which candidates may adopt. Furthermore, spatial theorists usually assume that utility functions have a shape common to all voters and that voters' most preferred positions are distributed in some regular manner. Employing these and attendant assumptions, the spatial theorist seeks to ascertain what deductions can be made about candidate strategies, i.e., the positions which vote or plurality-maximizing candidates should adopt in an election. It has been found that, in many situations, convergence to an opponent's positions and/or adoption of the median/mean of the most preferred positions of all voters is an important candidate strategy. In this context, two main problems have arisen: (1) difficulties of empirical or statistical analysis; (2) the abovementioned candidate strategy is generally not applicable to elections in so-called ‘plural’ societies. One path out of this latter problem has been formulated by Rabushka and Shepsle (1972). This article explores another potential solution by addressing the following question: If voters arenot characterized by cardinal utility functions, but some other type, what are the consequences for candidate strategies? The alternate assumption employed is that voters are characterized bylexicographic utility functions. The consequences for candidate strategies of this assumption are then determined for two plurality-maximizing candidates in some one- and two-dimensional, three-, five-, and seven-voter electoral games.     

Morphometrics of the hyoid bone for human sex determination from digital photographs

The identification of unknown remains is very important. When unknown remains are found, anthropologists first determine their sex and age. The sex of most skeletons is determined by their shape. In the hyoid bone, the shape is sex related, so it can be used forensically to determine the sex. This study focused on sex-based morphometry of the hyoid bone in Koreans using digital photographs. Hyoid bones from 52 males and 33 females were examined. For each subject, we took 34 measurements from photographs using a computer program, and the data were analyzed statistically using SPSS 11.0. Twenty-one of 34 measurements had significant sex differences (p<0.05). The discriminant functions based on three measurements (X(1)-X(3)) were as follows: The accuracy of discriminant functions is 88.2% in both groups, so these can be used to distinguish males from females in a statistically significant manner.     

Adults’ Judgments of Children's Coached Reports

This study investigated adults’ judgments of the honesty of children's coached true and fabricated mock testimony. Adults saw video clips of children testifying in a mock court about a true or fabricated event in their lives. They were asked to make an assessment of the truthfulness of the testimony, and respond to questions about their perception of children's credibility. Half of the adults saw children testifying after a competence examination, and the other half saw children testifying without a competence examination. Overall, girls were rated as more competent than boys, and their testimony was more likely to be believed. Younger children were more likely to be rated as incompetent than older children. A factor analysis of adults’ responses revealed six factors which significantly predicted adults’ overall assessment of children's credibility, and their evaluations of children's competence to testify. Adults’ detection accuracy was at chance, with the majority of children rated as truthful. Viewing the competency examination and cross-examination did not improve the adults’ detection accuracy. However, seeing the cross-examination made adults’ less likely to believe children's testimony. The implications of these results for the judicial system are discussed.     

Statutory interpretation and the counterfactual test for legislative intention

In this paper I examine the counterfactual test for legislative intention as used in Riggs v. Palmer. The distinction between the speaker's meaning approach and the constructive interpretation approach to statutory interpretation, as made by Dworkin in Law's Empire, is explained. I argue that Dworkin underestimates the potential of the counterfactual test in making the speaker's meaning approach more plausible. I also argue that Dworkin's reasons for rejecting the counterfactual test, as proposed in Law's Empire, are either too weak or unsound. A deeper reason for rejecting the counterfactual test as a method for the speaker's meaning approach is proposed in this paper. The difference between the counterfactual test and other tests for legislative intention which seem also to make use of counterfactual conditions in explained.     

Sexual violence among men in the military in South Korea

This research is about sexual violence among men in the military in South Korea. The authors investigated the frequencies, causes, and circumstances surrounding sexual violence and looked for characteristic features of sexual violence among men in the military in South Korea. They found a high frequency of physical sexual violence and a high level of repetition of sexual violence. Of perpetrators, 81.7% had themselves been victimized. However, the soldiers tended to minimize sexual violence, preferred not to address the issue if possible, criticized or ignored the victims, and did not trust the reporting procedures in place. The authors found that sexual violence was mobilized as a tool in the military to control hierarchy and to create certain masculinities. Regarding the relevance of masculinity, as a salient feature of militaries in general, they believed it might emerge as a common feature across national and cultural differences.     

Population genetics for Y-chromosomal STRs haplotypes of Chinese Korean ethnic group in northeastern China

Y-chromosomal STRs loci were analyzed from a sample of 201 healthy unrelated male individuals of Chinese Korean ethnic group. Allele and haplotype frequencies for DYS19, DYS385a/b, DYS388, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 were determined by the general PCR and silver staining methods. The gene diversity values for the Y-STRs loci ranged from 0.4146 (DYS437) to 0.9631 (DYS385a/b). A total of 194 haplotypes were identified in the Y-STR loci, among which 188 were unique, while 6 occurred more than once. And the combined haploytpes diversity was 0.9996. The results in the present study can be used for routine forensic application in the region, and enrich Chinese ethnical genetic informational resources.     

Competitors and Cooperators: A Micro‐Level Analysis of Regional Economic Development Collaboration Networks

Predispositions and orientation toward cooperation or competition with other jurisdictions can play a critical role in implementing regional collaboration. By examining collaboration at the micro level, this article investigates how individual factors, including perceptions of cooperation and competition, as well as institutional and environmental factors, are related to regional collaboration. In particular, the authors assert that competitive motivation may support the emergence of regional governance mechanisms. This article explores the relationships between competitive/cooperative motivations and interlocal collaboration networks based on a network survey conducted in the Orlando, Florida, metropolitan area. The authors apply a quadratic assignment procedure regression analysis to examine how dyadic conceptual ties of cooperation and competition, along with the effect of community characteristics, affect policy network structures for economic development. By comparing estimated coefficients with sampling distributions of coefficients from all of the permuted data sets, the regression results indicate the influences of perceived competition/cooperation on the network exchange.     

Who teaches and who learns? Policy learning through the C40 cities climate network

This study examines the network structure of policy learning in the C40 Cities Climate Leadership Group, which is a network of the world??s largest cities committed to tackling climate change issues. Among forty members and nineteen affiliate members, we ask the question with whom do cities learn and why? How are policy-learning relationships associated with cities?? multi-stakeholder governing body, policy performance, and cultural similarities? While studies on learning have analyzed conditions facilitating learning, quantitative studies of local government learning in global networks are rare. To facilitate the investigation into learning, we conceptualize learning as a process comprising information seeking, adoption and policy change, and focus on information seeking as the foundation step in the learning process. This social network analysis using the exponential random graph model reveals the cities that seek information and those that are information sources are different subgroups. Furthermore, analysis of nodal attributes suggests that transmunicipal learning in the C40 network is facilitated by the presence of a multi-stakeholder governing body; homophily of culture (language and regional proximity); and higher level of climate change policy performance. Creating a multi-stakeholder governing body could ensure participatory representativeness from citizens and relevant stakeholders to enhance climate change policy engagement and decision making as well as policy learning.     

Tolerance and economic growth revisited: a note

Berggren and Elinder (BE) in this journal write on the relationship between the degree of tolerance in a nation and its rate of economic growth. They are disturbed to find in their cross sections that faster economic growth statistically goes together with intolerance of homosexuals. In this comment, we revisit the issue and demonstrate that the concern expressed by BE is unwarranted if we properly account for ??conditional convergence?? in the regressions for economic growth. Other things being equal, a country grows faster if it starts from a poorer initial position. In the BE dataset, China since the Deng reforms is a prime example. At about the same time, another group of countries managed to accelerate their economic growth after a long period of stagnation: the ex-communist countries in central and Eastern Europe. Many of these nations also grew exceptionally fast for a number of years, once freedom had been regained and the initial chaos overcome. With simple modeling of these historical initial conditions, we find no statistical pattern that associates bias against homosexuals with weaker economic growth. Our results are robust under alternative specifications.
