Sampling from compositional and directional distributions

This paper describes a method for sampling from a non-standard distribution which is important in both population genetics and directional statistics. Current approaches rely on complicated procedures which do not work well, if at all, in high dimensions and usual parameter set-ups. We use a Gibbs sampler which seems necessary in practical situations of high dimensions.     

创新行为如何影响政府绩效:以领导干部任前公示为例的研究探索

在以往关注不同类型创新行为对组织绩效影响的研究中,组织氛围与沟通、人力资源与管理和行政成本是三类较为常见的影响因素,但三者尚未综合形成统一的框架。本研究选取了领导干部任前公示这一以人力资源管理为内容的创新行为,构建了三因素影响组织绩效的过程假设。通过分析问卷调查数据,发现三因素之间存在显著的相关性,且若按照组织边界划分绩效内容,三因素均与组织的内部成长建设绩效显著相关,而同组织外部绩效水平相关程度较弱。依此认为,创新行为影响绩效是一个由人、财、物三因素互动,并依据创新本身特点内容有所侧重的过程。     

Is the SOGS an Accurate Measure of Pathological Gambling Among Children, Adolescents and Adults?

The South Oaks Gambling Screen (SOGS) is widely used to assess the prevalence of pathological gambling. For a variety of reasons, this instrument may not provide an accurate rate of the prevalence of pathological gambling. In this paper, one source of error in data provided by the SOGS is investigated. It is argued that individuals may not fully understand the meaning of some items, and that clarification of the meaning of misunderstood items may in some cases lead to a changed score on the scale. The present study evaluates respondents' understanding of the SOGS items. The results from three studies are reported, each using a different sample: grade school children, adolescents and adults. It was hypothesised that (1) participants would not understand some items of the SOGS, (2) problem gamblers and probable pathological gamblers would be more inclined to interpret items incorrectly than would non-problem gamblers and, (3) consistent with the first two hypotheses, clarification of items would decrease the number of participants identified as problem gamblers or probable pathological gamblers. The data obtained supported hypotheses 1 and 3. Furthermore, hypothesis 2 was supported for grade school children, but not for adolescents or adults. These results are consistent with recent literature on endorsement and acquiescence phenomena, and have implications for prevalence studies of probable pathological gambling.     

Stalker profiles with and without protective orders: reoffending or criminal justice processing?

Research indicates that stalking is an extension of intimate partner violence. The overall purpose of this study was to better understand stalkers by examining the association between a protective order history and the court's processing of subsequent stalking, and to examine patterns of reoffending. This study examined a sample of 346 males who were charged with stalking in 1999 in one state. Subjects were partitioned into three groups: (1) males without protective orders; (2) males with one prior protective order; and (3) males with two or more prior protective orders. Almost two-thirds of the stalkers had a protective order against them at some point in the study, suggesting that stalking is associated with intimate partner violence. Results also found a linear trend with many of the criminal justice involvement variables and protective order history prior to 1999. Those charged with first-degree stalking were more likely to be found guilty initially, and about one-third of all three study groups had the initial felony stalking charge amended. Of those charged with second-degree stalking, only 7% of the group with two or more protective orders was initially found guilty, which was substantially less than the other two groups. And, when all the amendment dispositions were considered, there were no significant differences by group in guilty and dismissed dispositions for the index stalking charge. Further, consistent with previous criminal justice involvement, the group with two or more protective orders was more likely to have subsequent felony charges than the other two groups. Implications are discussed.     

“White Men Are This Nation:” Right‐Wing Militias and the Restoration of Rural American Masculinity*

Abstract The appearance of right‐wing militias was a much‐discussed phenomenon during the past decade. Commentators rightly pointed out their rural origins, their lower‐middle‐class and middle‐class composition, and their ideology rooted in racism, sexism, anti‐Semitism, and homophobia, but few, if any, have commented on the most salient aspect of all: that these are movements of men, who use narratives about masculinity as an analytic prism through which to understand their own situation and to problematize the identities of “others,” and as a rhetorical strategy to recruit and sustain their own membership. In this paper we undertake this analysis, exploring the rural origins of the militia movement, its social composition, ideology, and organization, and its articulation with other white supremacist groups. We argue that their vision of masculinity, particularly a self‐reliant, self‐made masculinity endemic to American history, is the theme unifying both the ideology and the organization of rural militias with the militant right‐wing continuum of which they are only a part.
