Implicit Leadership Theories in Applied Settings: Factor Structure, Generalizability, and Stability Over Time.

The present empirical investigation had a 3-fold purpose: (a) to cross-validate L. R. Offermann, J. K. Kennedy, and P. W. Wirtz's (1994) scale of Implicit Leadership Theories (ILTs) in several organizational settings and to further provide a shorter scale of ILTs in organizations; (b) to assess the generalizability of ILTs across different employee groups, and (c) to evaluate ILTs' change over time. Two independent samples were used for the scale validation (N1 = 500 and N2 = 439). A 6-factor structure (Sensitivity, Intelligence, Dedication, Dynamism, Tyranny, and Masculinity) was found to most accurately represent ELTs in organizational settings. Regarding the generalizability of ILTs, although the 6-factor structure was consistent across different employee groups, there was only partial support for total factorial invariance. Finally, evaluation of gamma, beta, and alpha change provided support for ILTs' stability over time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Verbal Representation and Therapeutic Change in Anaclitic and Introjective Inpatients.

This study examined the relation between changes in clinical functioning and changes in verbal expression in 81 seriously disturbed and treatment-resistant young adults seen in a comprehensive, psychoanalytically oriented inpatient treatment. Clinical functioning was evaluated with a battery of clinical and social measures. Verbal representations were assessed using computer-assisted scoring of Thematic Apperception Test responses. Changes in the frequency of verbal content and style in the narratives of these patients covaried with changes in clinical functioning. Significantly different covariations of verbal and clinical change, particularly differences in covariates of referential activity, were found for patients with anaclitic versus introjective personality configurations. The implications of these findings for understanding and treating severe psychopathology are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

洞庭湖流域某些水库,泉水和自然保护区环境水内的铀水平

一、前言 水库水,泉水,河水和大气降水等这些环境水与人类生活有着密切关系。水中天然放射性铀水平的研究因其化学毒性和放射性的双重危害是有实际意义的。洞庭湖流域处于我国亚热带湿润气候区,雨量充沛,矿产及水资源十分丰富。过去几年已对洞庭湖流域247000km~2湘、资、沅、澧各水系铀的水环境背景值,湘江的放射性水平和湘江流域大气降水中的痕量铀进行了研究。本文利用裂变径迹分析方法测定了洞庭湖流域的某些水库和泉水以及该     

点阴极电场辅助阳极连接中的紧密接触面积和电流

用等效电路的方法研究了点阴极情况下的电场辅助阳极连接效应，计算了连接电流，连接孕育期和紧密接触面积，本文结果表明，连接初期电流迅速衰减，随后缓慢变小，直至某一稳定值，孕育期随温度上升指数下降，连接温度高时，孕育期将难以观察到；待连接表面之间紧密接触面积随时间延长而非线性扩展，紧密接触区域增大时，其边界向外推进速度渐小，而接触面积增加渐快。     

屏蔽暂堵技术在青西地区的应用

对玉门油田青西地区裂缝性储层的保护方法 ,最有效的技术手段就是利用屏蔽暂堵技术。根据该地区储层岩性不同 ,分别选用聚磺、金属离子、阳离子钻井液体系 ,在原浆的基础上加入EP - 2、LF - 1和硅油消泡剂 ,配制成屏蔽暂堵钻井液体系。通过室内试验 :屏蔽暂堵钻井液体系API失水小于 5ml,HTHP失水小于 13ml,岩心渗透率恢复值大于 70 % ,起到了良好的屏蔽暂堵效果。经完井试油发现 ,储层污染明显减小 ,产量与邻井相比有大幅度提高
