Symptoms of Eating Disorders Among Females in Drug Addiction Treatment

The aim of this study is to measure and describe symptoms of eating disorders among females in treatment for drug addiction in Norway. Previous clinical and epidemiological studies have revealed coprevalence between eating disorders and substance use or abuse. However, few studies have measured eating disorders in drug-using samples and even fewer within the context of drug treatment. In this study, 29 females with drug use disorder in residential treatment were tested with the Eating Disorder Inventory–2. A subgroup of 9 females (31%) with significant symptoms of eating disorders was identified. The characteristics of this group and possible clinical consequences are discussed.     

Infill asymptotics for adaptive kernel estimators of spatial intensity

We apply the Abramson principle to define adaptive kernel estimators for the intensity function of a spatial point process. We derive asymptotic expansions for the bias and variance under the regime that n independent copies of a simple point process in Euclidean space are superposed. The method is illustrated by means of a simple example and applied to tornado data.     

Global Health Volunteering; Understanding Organizational Goals

This paper examines the goals of organizations that sponsor short-term volunteer trips in global health, whether they be NGO’s, faith-based, educational, or corporate organizations. Results from a U.S.-based national survey of 177 such organizations and 27 interviews with trip organizers suggest that organizations often sponsor volunteer trips to achieve goals that are quite different from the improvement of health outcomes in poor countries. While providing health services is often cited as the most important goal, volunteer activity is also considered important in enhancing the organizations’ reputation, recruitment and retention, and financial well-being. The prominence of other goals has the potential for diverting resources and focus from what is presumably the primary purpose of serving host communities in the most effective manner possible.     

Acculturation and adaptation of first‐ and second‐generation South Asians in Hong Kong

This study investigates the experiences of psychological and sociocultural adaptation among 404 first‐ and second‐generation South Asian immigrants in Hong Kong. Results indicate that for first‐generation immigrants, lack of host language fluency, fewer contacts and friendships with host members, the strategy of marginalisation, and perceived discrimination are all related to higher psychological distress, lower self‐esteem and less competence in sociocultural adaptation. For second‐generation individuals, although they reported higher knowledge of the host language and higher preferences the for assimilation strategy, the levels of psychological distress were higher compared with the first‐generation group. An interesting finding of this study is the preference for the marginalisation strategy as opposed to the assimilation and/or separation strategy. The findings of this study highlight the importance of considering the unique experiences of the second generation in order to further our understanding of immigration and acculturation processes.     

Basu–Dhar bivariate geometric distribution in the presence of covariates and censored data: a Bayesian approach

In this paper, we introduce classical and Bayesian approaches for the Basu–Dhar bivariate geometric distribution in the presence of covariates and censored data. This distribution is considered for the analysis of bivariate lifetime as an alternative to some existing bivariate lifetime distributions assuming continuous lifetimes as the Block and Basu or Marshall and Olkin bivariate distributions. Maximum likelihood and Bayesian estimators are presented. Two examples are considered to illustrate the proposed methodology: an example with simulated data and an example with medical bivariate lifetime data.     

研发模式对企业创新的影响——知识基础的调节作用

 在创新日益呈现出复杂性、系统性和不确定性的背景下，企业对合作研发和内部研发两种研发模式的合理选择及组合运用是提升创新效果的重要途径，但目前的相关研究仍存在一定局限性。一方面，合作研发和内部研发两种研发模式对不同类型创新(如突破式创新和渐进式创新)的影响机理和影响效果是否存在差异还未被厘清；另一方面，企业层面特征(如知识基础)对企业研发模式与企业创新关系的调节作用在已有研究中较少涉及。        针对上述研究现状和现实背景，整合知识基础观和创新管理相关理论，采用层级回归分析方法，收集310家制造企业数据，进行实证分析，研究企业合作研发和内部研发对其突破式创新和渐进式创新绩效的作用机理，以及知识深度和知识宽度对企业研发模式与企业创新关系的调节作用。        研究结果表明，相对于内部研发，合作研发对突破式创新绩效的影响更突出；相对于合作研发，内部研发对渐进式创新绩效的作用更为明显。知识深度在合作研发对突破式和渐进式创新绩效的影响中起正向调节作用，并正向调节内部研发与渐进式创新绩效的关系，但负向调节内部研发与突破式创新绩效的关系；知识宽度在内部研发对突破式和渐进式创新绩效的影响中起正向调节作用，并正向调节合作研发与突破式创新绩效的关系，负向调节合作研发与渐进创新绩效的关系。        在理论层面，考虑了不同研发模式对不同创新类型的影响，丰富了研发模式与企业创新领域的研究成果；引入知识基础作为调节变量，也为研发模式与企业创新之间权变因素的研究做出增量贡献；跳出了相关研究中关于合作研发与内部研发究竟是替代性还是互补性关系的争论，为后续研究提供了新思路。在管理实践层面，企业应根据自身的知识基础以及期望提升的创新类型来选择合适的研发策略。     

全球一体化催生的一株诗坛奇葩——中韩生态环境诗兴起脉络初探

西方发达国家于20世纪60年代产生的生态文学,在东西方冷战结束后,影响到了中韩两国的诗歌创作,20世纪80年代后,中韩两国诗坛上先后兴起生态环境诗。虽然中韩在社会基础、诗歌自身发展等因素上存在着各自差异,但在全球一体化的语境下,生态环境诗则形象地表达了两国诗人对工业文明的共同思考。     

Effects of attributed responsibility and response strategies on organizational reputation: A meta-analysis of situational crisis communication theory research

Scholars utilizing situational crisis communication theory (SCCT) mainly examine how attributed responsibility affects organizational reputation and how response strategies matched with the amount of attributed responsibility protect reputation. The findings on these 2 important questions have been mixed. A meta-analysis of 35 investigations from 24 studies published between January 1990 and March 2015 was conducted to explain the mixed findings and reveal average correlations. Attributed responsibility was strongly associated with reputation at –.54, and response strategies were only weakly associated with reputation at .23. Equally important, crisis vignette choice moderated the responsibility-reputation association. Crisis clusters, reputation measurements, sample choice, and crisis vignette choice moderated the match-reputation association. Theoretical, methodological, and practical implications were discussed.
