Utilizing records from the Seattle Police Department, we explored questions of a new “masculinized” female offender and a “chivalrous” criminal justice system. Crime‐specific arrest statistics provided a means to study both questions. Arrest statistics were recoded three separate ways: according to traditional views of the “masculinity” of an offense; legalistic crime categories; and seriousness ratings. These three categories were compared by sex across a four‐year period. Comparisons of final dispositions provided the basis of a final look at the “chivalry” issue. The findings suggest that females are not making great inroads into either traditionally masculine crimes or crime in general, and while there is little in the data to suggest prejudicial treatment based on sex, chivalry is supported by certain arrest and disposition rates.  相似文献

Limitations in currently available methods for producing significance probabilities for the sign test are discussed. Two simple modifications to the continuity corrected normal approximation are derived and presented in a simple form. These modifications are shown to markedly reduce the relative error in approximating exact probabilities. The relative simplicity of these modifications and the importance of accurate p values suggest that one or both modifications could be useful improvements.  相似文献

Recent presidents find greater proportions of their executive nominations encountering substantial opposition in the Senate. What accounts for failed nominations to senior-level executive positions? We address this question by examining 297 cabinet and other senior-level nominations between 1969 and 2012, testing multivariate models of the effects of the partisan and ideological composition of the Senate, the president's public approval and electoral mandate, and characteristics of the nominee. The analysis demonstrates that allegations of illegal or unethical behavior by the nominee and concerns over policy preferences best explain the Senate's response to executive nominations. It is clear that, unlike legislative outcomes, confirmation outcomes are the products of nominee-centered factors with presidency-centered factors and Congress-centered factors having little impact on Senate decisions.  相似文献

In this article we explore social movement solidarity through an examination of narratives offered by participants in a metaphysical movement. Drawing from contemporary social movement theory, we focus on how members develop a carefully built collective identity that perpetuates movement goals and ideology. Data for this project are drawn from in-depth interviews with local psychics, participant observation in various metaphysical fairs, and document analysis. We find that the movement's collective identity is centered around several narratives that help establish boundaries, identify antagonists, and create a collective consciousness. Together these narratives form a web of belief that binds members to the movement. The data we present in this article have implications for understanding other expressive movements, as well as for social movement theory in general.  相似文献

Researchers have argued for increased collaboration between teachers and museum educators to improve the outcomes of museum education on students; however, significant gaps in understanding between the two remain impediments to effective collaboration. We surveyed fifty-one museum educators, conducted in-depth interviews with ten of these respondents, and analyzed the data with use of an inductive lens. In this article we use a composite dialogue between a museum educator and a teacher to present a series of questions teachers should ask of, and information they should provide to, museum educators. Such questions and information can be used to initiate more effective collaborative relationships that may ultimately improve the quality of museum education for our students. We argue that gaps in museum educators’ understanding about teachers’ needs, objectives, and concerns about museum visits could be bridged if teachers knew what questions to ask and what information to volunteer to museum educators before arranging a museum visit.  相似文献

The kind of interdependencies between decentralized departments determines the objective of coordination as well as the applicability of several coordination instruments. This paper examines two decentralized departments of one company joining a cross-firm value network with existing sales interdependencies. It compares a contribution margin based, a revenue based and a quantity based compensatory payment as coordination instruments for inducing efficient quantity and investment decisions. As a general result, conditions are identified for which ordained coordination instruments dominate other mechanisms with respect to the expected firm wide profit.  相似文献

A paramecer-free Bernstein-type upper bound is derived for the probability that the sum S of n i.i.d, unimodal random variables with finite support, X1 ,X2,…,Xn, exceeds its mean E(S) by the positive value nt. The bound for P{S - nμ ≥ nt} depends on the range of the summands, the sample size n, the positive number t, and the type of unimodality assumed for Xi. A two-sided Gauss-type probability inequality for sums of strongly unimodal random variables is also given. The new bounds are contrasted to Hoeffding's inequality for bounded random variables and to the Bienayme-Chebyshev inequality. Finally, the new inequalities are applied to a classic probability inequality example first published by Savage (1961).  相似文献

This paper considers the problem of using control charts to simultaneously monitor more than one parameter with emphasis on simultaneously monitoring the mean and variance. Fixed sampling interval control charts are modified to use variable sampling intervals depending on what is being observed from the data. Two basic strategies are investigated. One strategy uses separate control charts for each parameter, A second strategy uses a proposed single combined statistic which is sensitive to shifts in both the mean and variance. Each procedure is compared to corresponding fixed interval procedures. It is seen that for both strategies the variable sampling interval approach is substantially more efficient than fixed interval procedures.  相似文献
