Narcissism, sexual refusal, and aggression: Testing a narcissistic reactance model of sexual coercion.

Laboratory analog studies investigated the theory that narcissism and reactance contribute to causing rape. In Study 1, narcissism correlated positively with rape-supportive beliefs and negatively with empathy for rape victims. In Study 2, narcissists reported more enjoyment than other men of film depictions that presented consensual, affectionate activity followed by rape (but not in response to either affection or rape alone). In Study 3, narcissists were more punitive than other men toward a female confederate who refused to read a sexually arousing passage aloud to them.

Inference control of open relational queries under closed-world semantics based on theorem proving

Relational database systems may serve to evaluate an open query under closed-world semantics. The evaluation returns an explicit output relation complemented with an often implicit statement about the completeness of that relation. The output relation is formed from all those tuples that both fit the format and satisfy the properties expressed in the query. Using first-order logic for specifying formal semantics, the output relation can be seen as a set of (ground) sentences obtained from the query formula by suitable substitutions of free variables by constants. A statement about the completeness of a relation can also explicitly be formalized as a sentence of first-order logic. Inference control for enforcing a confidentiality policy has to inspect and to possibly distort not only the sentences representing the tuples of the output relation but also the completeness sentences. Previously designed and formally verified control procedures employ theorem-proving for such inspections while iteratively considering candidates for those sentences and determining termination conditions, respectively. In this article, we outline an implementation of these control procedures and treat improvements of their runtime efficiency, in particular to overcome shortcomings of the underlying theorem prover, which is repeatedly called with an input comprising a completeness sentence of increasing size. The improvements are obtained by an equivalent rewriting of completeness sentences, exploiting the active domain or introducing new constants for combinations of the original constants, respectively, as well as by optimizing the number of such calls. Besides theoretical complexity considerations, we also present practical evaluations for some examples. These examples include queries that—without control—would return the whole underlying database relations and—with control—can be used for confidentiality-preserving data publishing.

Review of Canadian mental health law and policy.

Reviews the book, Canadian Mental Health Law and Policy by John E. Gray, Margaret A. Shone, and Peter F. Liddle (2000). The authors of this book have produced a multidisciplinary text that succinctly summarizes the main points of Canadian mental health laws and the variability across provinces and territories in these laws and in their typical interpretation and application. This book offers a concise guide to the laws dealing with key issues such as involuntary hospital admission, authorization of psychiatric treatment, and treatment refusal. Although not always an easy read for those unfamiliar with legal terms and writing, the book is geared to a wide audience that includes legal and policy specialists, mental health professionals, and advocates for the mentally ill. These authors are to be congratulated for their efforts to disseminate and explain information on Canadian mental health law and to promote a more humane and scientifically grounded set of legal standards and interpretations that are pertinent to the disposition and treatment of Canadian citizens with severe mental disorders.

Volunteering as a function of field structure.

It was predicted that significantly more volunteering would occur when test Ss observed the invitation (to participate in an experiment) being accepted prior to their being asked than would occur in the control condition (where S had no opportunity to observe the behavior of others in the invitation situation); and significantly less when refusal was observed, as compared with the control condition. The results support the predictions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

负序方向元件在同杆双回线中的动作行为分析

由于同杆双回线自身的特殊性,使得在常规线路保护中有着广泛应用的负序方向元件的性能受到影响。从同杆双回线的故障特点出发,利用六序故障分量法分析了负序方向元件在同杆双回线各种典型故障情况下的动作行为。结果表明,在发生ⅠBCⅡBG,ⅠBCⅡCG跨线故障时,Ⅱ回线两侧的负序方向元件有可能拒动;在发生ⅠAⅡBCG,ⅠABCⅡBCG,ⅠABCⅡAG跨线故障时,两回线路总有一回线路两侧的负序方向元件拒动。利用电磁暂态仿真软件PSCAD/EMTDC搭建同杆双回线仿真模型,仿真结果也验证了这一结论。
