There are more women employed by police agencies today than ever before. Their role and workplace experiences have changed significantly from the time that they were first employed as police matrons in the late 1800s‐early 1900s. This article covers the history of women in policing. It provides an overview of past and contemporary research focused on female police officers. A trend found in the contemporary research reveals that there are many similarities among male and female police officers. This trend is interesting as policing has traditionally been a male dominated profession in the United States. 相似文献

This study examined effects of cognitive-behavioral couple therapy (n = 25 couples) and a variety of systems-oriented couple therapy models (n = 30 couples) in reducing negative attributions and degrees to which decreases in negative attributions were associated with improvements in other aspects of relationship functioning. Couples seeking treatment at a university clinic and experiencing psychological and/or mild-to-moderate physical abuse completed 10 weekly sessions. Attributions, relationship satisfaction, psychological abuse, communication, and negotiation were assessed before and after treatment. Women and men in both treatments exhibited decreased negative attributions, which moderated increases in satisfaction and decreases in negative communication, as well as increases in positive communication for men. The findings reinforce the importance of modifying negative attributions when intervening to reduce abuse. 相似文献

This paper reports an extension of valence-instrumentality-expectancy (VIE) type models of organizational choice to the decision process of high school students selecting undergraduate colleges. Using questionnaire data from 714 respondents, interactive vatence-instrumentality models correctly predicted 68% of actual choices. A number of alternative models are evaluated, and several areas for refinement and extension of this study are identified. 相似文献

The 16-City Study analyzed for gas-phase environmental tobacco smoke (ETS) constituents (nicotine, 3-ethenyl pyridine [3-EP], and myosmine) and for particulate-phase constituents (respirable particulate matter [RSP], ultraviolet-absorbing particulate matter [UVPM], fluorescing particulate matter [FPM], scopoletin, and solanesol). In this second of three articles, we discuss the merits of each constituent as a marker for ETS and report pair-wise comparisons of the markers. Neither nicotine nor UVPM were good predictors for RSP. However, nicotine and UVPM were good qualitative predictors of each other. Nicotine was correlated with other gas-phase constituents. Comparisons between UVPM and other particulate-phase constituents were performed. Its relation with FPM was excellent, with UVPM approximately 1 1/2 times FPM. The correlation between UVPM and solanesol was good, but the relationship between the two was not linear. The relation between UVPM and scopoletin was not good, largely because of noise in the scopoletin measures around its limit of detection. We considered the relation between nicotine and saliva cotinine, a metabolite of nicotine. The two were highly correlated on the group level. That is, for each cell (smoking home and work, smoking home but nonsmoking work, and so forth), there was high correlation between average cotinine and 24-hour time-weighted average (TWA) nicotine concentrations. However, on the individual level, the correlations, although significant, were not biologically meaningful. A consideration of cotinine and nicotine or 3-EP on a subset of the study whose only exposure to ETS was exclusively at work or exclusively at home showed that home exposure was a more important source of ETS than work exposure. 相似文献

Perceived-control 'describes individuals'generalized beliefs about their abilities to influence their life courses and circumstances. Most research concerning this construct has viewed perceived control as a developmentally acquired, stable personality characteristic. Others argue that perceived control is determined by current social status, with more privileged social positions contributing to increased control over life circumstances.
This study analyzes data from the Virginia Twin Registry to determine the independent contributions of genetics, shared environment, and nonshared environment, including adult roles and statuses, on women's perceived control. Findings from latent variable twin models suggest that there are modest but significant effects of shared environment and genetics on perceived control but that the majority of individual variation in perceived control is due to nonshared environmental factors on perceived control among adult women. Analyses of measured individual-level variables indicate significant effects from education, income, earnings, marital quality, age, and single-parent status. 相似文献

The purpose of this study was to document health care providers' awareness of problem gambling and frequency of recognition and treatment. An exploratory survey was designed to collect data on awareness and knowledge of problem gambling. A structured questionnaire was completed anonymously by 180 health care providers (nurses, physicians, social workers, and other allied health professionals). Almost all respondents (96%) reported knowledge of problem gambling, and 30% reported asking clients about gambling problems when they presented with stress related symptoms. A third of the respondents reported identifying and treating clients for a gambling problem. The most frequently reported intervention was referral to counseling and other gambling resources. Respondents were generally interested in learning more about gambling problems, particularly those providers who have had a client discuss gambling related concerns. There were no significant differences in findings between provider groups. 相似文献

‘Success’ in drug development is bringing to patients a new medicine that has an acceptable benefit–risk profile and that is also cost‐effective. Cost‐effectiveness means that the incremental clinical benefit is deemed worth paying for by a healthcare system, and it has an important role in enabling manufacturers to obtain new medicines to patients as soon as possible following regulatory approval. Subgroup analyses are increasingly being utilised by decision‐makers in the determination of the cost‐effectiveness of new medicines when making recommendations. This paper highlights the statistical considerations when using subgroup analyses to support cost‐effectiveness for a health technology assessment. The key principles recommended for subgroup analyses supporting clinical effectiveness published by Paget et al. are evaluated with respect to subgroup analyses supporting cost‐effectiveness. A health technology assessment case study is included to highlight the importance of subgroup analyses when incorporated into cost‐effectiveness analyses. In summary, we recommend planning subgroup analyses for cost‐effectiveness analyses early in the drug development process and adhering to good statistical principles when using subgroup analyses in this context. In particular, we consider it important to provide transparency in how subgroups are defined, be able to demonstrate the robustness of the subgroup results and be able to quantify the uncertainty in the subgroup analyses of cost‐effectiveness.
