小型密闭压力容器测试系统重复性的研究

小型密闭压力容器测试（MCPVT）法是安全工程领域中近几年发展起来的、评价有机过氧化物及自反应物质受热分解反应激烈程度的新方法。pmax是MCPVT方法中用来表征自反应物质受热分解反应激烈程度的物理量之一。文中通过大量实验，研究了样品容器容积V、升温速率R及样品质量M对pmax重复性误差的影响，研究了一系列典型的有机过氧化物和自反应物质在标准实验条件下pmax重复性误差。结果表明，小型密闭压力容器测试系统重复性好，测试结果可靠，从而为MCPVT法最终成为国际上评价自反应物质受热分解反应激烈程度标准方法奠定了基础。

The Self and Object Representations of Narcissistically Disturbed Children: An Empirical Investigation.

The aim of this study was to demonstrate a correlation between the clinical assessment of narcissistic personality disorder in children and underlying self and object relationships. D. Westen's Social Cognition and Object Relations Scale for the Thematic Apperception Test (1995; D. Westen, N. Lohr, K. Silk, K. Kerber, & S. Goodrich, 1985) was used to compare the object representations of two groups of referred latency-aged children, one for whom narcissistic issues were thought to be primary. Support for the clinical literature, which describes these children as lacking in empathy, struggling with self-esteem regulation, and in poor control of their impulses or aggression, was found. Additionally, a tendency to have a vulnerable sense of identity and to be preoccupied with seeking out and developing relationships with others was found to differentiate these children from peers with similar behavioral and diagnostic profiles. Results obtained have potential implications for the assessment and treatment of narcissistically disturbed children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

硅外延片中的杂质控制

有5类掺杂源影响硅的外延片中的杂质分布。主掺杂质控制外延层的杂质浓度，决定外延层的电阻率。固态外扩散、气相自掺杂和系统自掺杂影响衬底界面附近的外延层杂质浓度的深度分布。该文介绍了此3类掺杂源的掺杂过程和抑制方法。金属杂质在外延层中对器件有害，防止沾污和使用吸杂技术能降低金属杂质在外延层中的浓度。     

Disentangling achievement orientation and goal setting: Effects on self-regulatory processes.

H. Heckhausen and J. Kuhl's (1985) goal typology provided the conceptual foundation for this research, which examined the independent and integrated effects of achievement orientation and goal-setting approaches on trainees' self-regulatory activity. Using a complex computer-based simulation, the authors examined the effects of 3 training design factors--goal frame, goal content, and goal proximity--cutting across these 2 theoretical domains on the nature, focus, and quality of the self-regulatory activities of 524 trainees. Results revealed that all 3 factors had a significant influence on self-regulation, with goal content exhibiting the greatest influence. In line with expectations, congruent learning frame and content compared with congruent performance frame and content was beneficial for trainees' self-regulatory activity, incongruent combinations of goal frame and content were better than congruent performance frames and content, and effects for the incongruent combinations cutting across the domains were asymmetrical. Theoretical extensions for further disentangling these distinct domains and training design implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-efficacy and work-related performance: The integral role of individual differences.

The present study estimated the unique contribution of self-efficacy to work-related performance controlling for personality (the Big 5 traits), intelligence or general mental ability, and job or task experience. Results, based on a meta-analysis of the relevant literatures, revealed that overall, across all studies and moderator conditions, the contribution of self-efficacy relative to purportedly more distal variables is relatively small. Within moderator categories, there were several cases in which self-efficacy made unique contributions to work-related performance. For example, self-efficacy predicted performance in jobs or tasks of low complexity but not those of medium or high complexity, and self-efficacy predicted performance for task but not job performance. Overall, results suggest that the predictive validity of self-efficacy is attenuated in the presence of individual differences, though this attenuation does depend on the context.

Preparation of branched polyacrylonitrile through self‐condensing vinyl copolymerization

Branched polyacrylonitrile (PAN) was prepared through a self‐condensing vinyl copolymerization of acrylonitrile and 2‐(2‐bromopropionyloxy)ethyl acrylate (BPEA). The branched architecture of the product was confirmed by NMR spectra and the average degree of branching (DB ) was estimated. Through a comparison of the intrinsic viscosity of the product with that of its linear analogue, the contraction factor g′ was calculated. It was found that the viscosity of the branched PAN was obviously lower that that of linear PAN. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008     

Mind, brain, and self in psychoanalysis: Therapeutic implications of the mind-body relation.

Theoretical and empirical findings regarding the mind-body relation and its integration within a concept of the self-as-person lead to certain therapeutic implications and applications. The mind-set of the analyst or psychotherapist regarding the integration of mind-body can have important reverberations, which can dictate decisions for therapeutic intervention and management. Implications for conceptualizing technical modifications in analytic therapy are suggested. Conceptualization of mind and brain operating as an integrated and functional unity contribute to better understanding aspects of mental functioning that remain beyond the reach of conscious awareness and direct therapeutic processing. Particular attention is paid to the issue of combining medications clinically with psychotherapy and psychoanalysis. Future integration of psychoanalysis with advancing trends in therapeutic intervention and with rapidly expanding neurobiological understanding of mental actions as related to brain activity may require a deepening awareness of complexities of the mind-body relation and a more analytically meaningful resolution of the problem.
