Psychometric Properties of the Differentiation of Self Inventory‐Revised in Turkish Adults

The purpose of the current study was to examine the validity and reliability of (Journal of Marital and Family Therapy 2003, 29, 209) Differentiation of Self Inventory‐Revised (DSI‐R; Skowron & Schmit, 2003) in Turkish adults. The DSI‐R was translated, independently back‐translated, and revised. Two independent samples of adults over the age of 25 were used. The original 46‐item DSI‐R was not supported by the data derived from Sample 1 (n = 221). However, a revised 20‐item, four‐factor model fit the data well. This 20‐item model was subsequently cross‐validated with a second sample of Turkish adults (n = 187). Scale scores showed adequate internal consistency, 5‐week test–retest reliability, and satisfactory convergent and criterion‐related validity. It was concluded that Turkish DSI‐R (DSI‐T) is a valid and reliable measure to assess an individual's differentiation level. In light of the findings, implications for the use of the DSI‐T and ideas for future research are discussed.     

受访者推动抽样：研究隐藏人口的方法与实践

“隐藏人口”的特点是规模较小且成员一般不愿暴露身份，因此很难使用常规抽样方法对其进行研究。近年来出现了一种新的研究隐藏人口的方法——受访者推动抽样（RDS)方法，该方法在传统“雪球抽样”方法的基础上，结合社会网络分析的理论和方法，使研究者有可能根据样本对总体特征做出合理的推论。本文对RDS方法的理论渊源、基本思路、主要操作步骤和原理进行了简要介绍，并探讨了在实际操作过程中应注意的问题。     

The Prevalence of Destructive Leadership Behaviour

This study investigates the prevalence of the four types of destructive leadership behaviour in the destructive and constructive leadership behaviour model, in a representative sample of the Norwegian workforce. The study employs two estimation methods: the operational classification method (OCM) and latent class cluster (LCC) analysis. The total prevalence of destructive leadership behaviour varied from 33.5% (OCM) to 61% (LCC), indicating that destructive leadership is not an anomaly. Destructive leadership comes in many shapes and forms, with passive forms prevailing over more active ones. The results showed that laissez‐faire leadership behaviour was the most prevalent destructive leadership behaviour, followed by supportive–disloyal leadership and derailed leadership, while tyrannical leadership behaviour was the least prevalent destructive leadership behaviour. Furthermore, many leaders display constructive as well as destructive behaviours, indicating that leadership is not either constructive or destructive. The study contributes to a broader theoretical perspective on what must be seen as typical behaviour among leaders.     

On-line bin packing with restricted repacking

Semi-on-line algorithms for the bin-packing problem allow, in contrast to pure on-line algorithms, the use of certain types of additional operations for each step. Examples include repacking, reordering or lookahead before packing the items. Here we define and analyze a semi-on-line algorithm where for each step at most k items can be repacked, for some positive integer k. We prove that the upper bound for the asymptotic competitive ratio of the algorithm is a decreasing function of k, which tends to 3/2 as k goes to infinity. We also establish lower bounds for this ratio and show that the gap between upper and lower bounds is relatively small.     

Internet Technology in Service of Personal Health Care Management: Patient Perspective

Internet technology has become an informational resource for most health care consumers. Online information, discussion, and support groups, in the form of message boards, listservs, and chat rooms are emerging as parts of virtual self-health-care network. This paper examines the extent to which participation in online health discussion groups was reported to be helpful in increasing medical knowledge and in enhancing the participatory patient role of health care consumers in interaction with health care service professionals. Data for this study was collected from 350 patients who participated in Internet discussion groups for cancer patients. The findings of the study indicated the important impact of Internet health discussion groups on health care management practices as perceived by health care consumers, including empowerment through knowledge and proactive participation in cancer care management. This research contributes to understanding the patient perspective and assesses the perceived importance of Internet groups by health care consumers.     

一场西式婚礼的音乐盛宴

每对恋人心中都曾描绘过自己婚礼的样子，草地、白色婚纱、教堂……除了这些婚礼上该有哪些好听的音乐？从古代开始结婚的时候就会用音乐来表达那份喜庆的心情。敲着锣、打着鼓、吹着唢呐、放着鞭炮、抬着花轿．包括现在很多地方仍旧保持着这种传统的结婚方式。但是受到西方文化影响的我们．逐渐被婚纱教堂的仪式诱惑，当穿着黑皂的晚礼服和洁白神婚纱举行婚礼的当天，
