Examining Dose–Response Relationships Between Childhood Victimization,Depression, Symptoms of Psychosis,and Substance Misuse for Incarcerated Women

The current study uses the dose–response model to examine the relationships between childhood victimization events and subsequent depression, symptoms of psychosis, and substance misuse in a sample of 230 randomly selected incarcerated women in the United States. Results on the frequency of victimization were mixed. In this sample, both frequency of physical abuse and frequency of sexual abuse significantly predicted current symptoms of psychosis, but only frequency of physical abuse significantly predicted substance misuse. Incarcerated women who experienced multivictimization were 5.7 times as likely to report depression, 4.2 times as likely to report current symptoms of psychosis, and 3.8 times as likely to meet criteria for a substance use disorder. Results indicate that adjusting prison-based interventions to address multivictimization may improve outcomes and reduce recidivism among this population.     

中国汉族人颅骨数字模型的性别判别方法

目的利用步进Fisher法建立多元性别判别函数,对西安地区成年人颅骨进行性别判别。方法从颅面数据库中选择西安地区133个（73男,60女）三维颅骨模型,利用计算机软件测量并统计颅骨的12项几何测量指标和2项角度测量指标,利用步进Fisher方法建立多元性别判别函数,并对方程进行回代检验。结果男性的12项几何测量指标均值大于女性,女性的2项角度测量指标均值大于男性,除2项指标（X7和X14）外,其他指标均存在显著性差异（P〈0.01）。由4项指标建立的判别方程,判别率男性为87.5%,女性为86.67%。结论利用计算机软件可以实现完整颅骨和无下颌的颅骨的性别判别。     

基于CT扫描并图像重组青少年锁骨胸骨端骨龄数学模型

目的利用我国青少年锁骨胸骨端骨骺发育变化规律,探讨CT容积再现(volume rendering,VR)数据与生物学年龄的相关性,并建立推断骨龄的数学模型。方法通过对我国华东、华南地区684名15~25周岁青少年双侧锁骨胸骨端进行CT薄层扫描并VR三维图像重组,测量并计算双侧锁骨胸骨端骨骺最长径、干骺端最长径及其长度比、骨骺面积、干骺端面积及其面积比等数据,并建立骨龄推断的数学模型。再将50例训练样本代入数学模型,检验模型的准确性。结果左、右两侧骨骺与干骺端长度比、面积比在同一年龄组男女性间差异具有统计学意义(P0.05)。建立的数学模型表明锁骨胸骨端骨骼的发育规律与生物学年龄具有高度的相关性,所有模型的准确率都高于70.5%(±1.0岁)和82.5%(±1.5岁)。结论建立的骨龄数学模型的可操作性强、准确性较高。这不仅可与图谱法相互印证和支持,提高骨龄推断的准确性;同时,该方法对未来研究其他单一部位骨龄推断具有重要的意义。     

美国医疗纠纷替代性解决机制研析

美国医疗纠纷替代性纠纷解决机制卓有成效,其不仅包含作为传统非讼手段的调解、仲裁、和解,还创设出监察员制度、事实调查、建立共识、混合式ADR、聘雇退休法官程序、微型审理、简易陪审团审判、诉前审查庭等多种方式。因受到司法机关与行政单位的重视和民间团体的大力支持,美国ADR制度已经发展成为与民事诉讼制度双轨并行、相互补充的重要纠纷解决机制。针对我国今年医闹事件频发,伤医事件愈演愈烈的情况,将ADR机制导引入国内医疗纠纷领域,不失为一条缓和医患关系、促进医患沟通、妥善解决医疗纠纷的有效可行的途径。     

医院设置医务社会工作部门相关问题研究

医务社会工作是一种助人性质的工作,在医院内的职能包括开展个案辅助工作、协调医患关系等。医务社会工作在医院内作为一个独立的部门也会遇到很多问题,因此应该提供相应策略,从而让医务社会工作更好地为医院服务,为构建和谐社会贡献自己的力量。     

The Demand for Cinema in Sweden: An Application of Proportional Odds Model

ABSTRACT

This article examines the determinants of demand for cinema using a randomly drawn sample of the movie-going population in Sweden. A proportional odds model is applied to capture the natural ordering of dependent variables and any inherent nonlinearities. The findings show that individual demand for cinema depends on gender, age, educational attainment, income, marital status, critical reviews, word of mouth, and willingness to pay. The fact that cinema demand is correlated with economic and socio-demographic variables has important implications for theoretical and empirical research in cultural economics and human decision-making processes.     

Contracting Out Parks and Recreation Services: Correcting for Selection Bias Using a Heckman Selection Model

Despite the growing scholarly attention on the efficiency rationale of contracting out, the empirical evidence to support claims that contracting out service delivery reduces service costs has not been forthcoming. Using transaction cost theories, this research explores park and recreation service provision costs across contractor sectors, controlling for the choice to contract out a service or not. The two-stage Heckman model indicates the importance of competitive markets and economies of scale in reducing transaction cost risk which local governments must face. This research also addresses how state and local institutional settings define the context in which policy decisions are made and implemented.     

An Information Model to Present Proposals to Increase Taxes: Two Examples in the Context of American Values

This article offers an information model for educating the public on the rationale for a tax increase. It argues that citizens exposed to two types of information—a need narrative and an anchor value—are more willing to support a tax increase. The applicability of the model is illustrated with two examples in which the model was used to structure the presentation of information. In both situations, exposure to the specific types of information suggested by the model is associated with support for a tax increase. The conclusion relates the model to the findings of previous research on the attributes of successful referenda campaigns for tax increases.     

Do Role Clarity and Job Satisfaction Mediate the Relationship between Telework and Work Effort?

The empirical association between telework and work effort, as well as how this relationship is mediated by role clarity and job satisfaction, is lacking in the literature. As a consequence, the direct and indirect impact of telework on work effort in U.S. federal government agencies was examined in the article. Results indicate that telework was inversely related to work effort. Moreover, role clarity and job satisfaction did not mediate the relationship between telework and work effort. The implications these results have for theory and practice are thoroughly discussed in the article.     

Between poverty and prosperity: China’s dependent development and the ‘middle-income trap’

Despite China’s rapid economic growth in the past three decades, Chinese officials and experts are increasingly worried that the country is slowly heading towards the ‘middle-income trap’. The fear is that China might suffer the same stagnation and turbulence as Latin American economies did in the 1980s and 1990s. Will China be able to avoid this trap? Building on the insights of world-systems theory, this paper argues that China’s dependent development, although enabling it to escape the ‘poverty trap’, is likely to bog it down in the ‘middle-income trap’. China’s heavy reliance upon foreign technologies and investment has harmful effects on its economy. Dependent development not only increases China’s economic vulnerability but also truncates domestic industries. To escape the trap, the Chinese state should play a more active role in shifting its growth model away from low-end commodity manufacturing to knowledge-based, high value-added activities.
