论企业集团的发展动力

近代系统科学的研究成果表明,现实的系统,不论是自然科学领域的、社会科学领域的,乃至整个宇宙的,都是开放的系统,处在一定的环境之中,并不断地和环境及其它系统相互作用,交换物质和能量。开放系统具有一种内在能力,使系统本身由一种状态转移到另一种状态,这种能力就是系统的自组织能力。耗散结构理论进一步指出,一个远离平衡的开放系统（不论是力学的、物理学的、化学的、生物学的系统,还是社会的、经济的系统）,通过不断地与外界交换物质和能量,在外界条件达到一定阈值时,就能从原先的无序状态,转变为一种在时空上或功能上…

浅析企业财务风险的成因及防范对策

一、企业财务风险的成因分析 第一,企业财务管理的宏观环境复杂多变,财务管理系统不能适应复杂多变的宏观环境.目前,我国许多企业建立的财务管理系统,由于机构设置不尽合理,管理人员素质偏低,财务管理规章制度不健全,管理基础工作欠缺等原因.导致企业财务管理系统缺乏对外部环境变化的适应能力和应变能力.具体表现在企业不能对外部环境的变化进行科学的预见,反映滞后,措施不力,由此产生财务风险.     

人心齐泰山移

过去的２００２年是令人难忘的。这一年，万众瞩目的十六大召开了。十六大中亮点很多，其中参会的民营企业代表就是亮点之一，为此吸引了很多记者。人们普遍认为，十六大的召开，是民营企业春天的真正到来。中国的民营企业是有生命力的。新中国成立后，由于我们工作中左的错误，特别是经过文化大革命，民营企业在大陆几乎绝迹。改革开放后，有了合适的环境，民营企业便像具有顽强生命力的幼苗，破土而出，成长壮大。邓小平同志曾经说过，乡镇企业异军突起，三分天下有其一，这是我们没有预料到的最大收获，这说明中央制定的搞活政策是对头的…

Structural contingency theory and individual differences: Examination of external and internal person-team fit.

This article develops and tests a structurally based, integrated theory of person-team fit. The theory developed is an extension of structural contingency theory and considers issues of external fit simultaneously with its examination of internal fit at the team level. Results from 80 teams working on an interdependent team task indicate that divisional structures demand high levels of cognitive ability on the part of teammembers. However, the advantages of high cognitive ability in divisional structures are neutralized when there is poor external fit between the structure and the environment. Instead, emotional stability becomes a critical factor among teammembers when a divisional structure is out of alignment with its environment. Individual differences seem to play little or no role in functional structures, regardless of the degree of external fit. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Factors Affecting the Success of a Construction Project

Different researchers have tried to determine the factors for a successful project for a long time. Lists of variables have been abounded in the literature, however, no general agreement can be made. The aim of this paper is to develop a conceptual framework on critical success factors (CSFs). Seven major journals in the construction field are chosen to review the previous works on project success. Five major groups of independent variables, namely project-related factors, project procedures, project management actions, human-related factors, and external environment are identified as crucial to project success. Further study on the key performance indicators (KPIs) is needed to identify the causal relationships between CSFs and KPIs. The causal relationships, once identified, will be a useful piece of information to implement a project successfully.

对《骆驼祥子》中祥子悲剧命运的深度探析

《骆驼祥子》塑造了祥子这一典型悲剧形象。祥子的悲剧是力求生存的强者的悲剧,其悲剧命运根源于病态的社会环境和病态的个人因素,而社会环境因素是小说所着力揭示、呈现的。对于祥子的悲剧命运,以及悲剧命运的成因,一方面,我们应该从感性观照方面把握,另一方面则应该以此为基础作出深层次的理性思考。

Behavior and behavioral needs

An understanding of behavior is important in any consideration of poultry welfare. Behavior is a good indicator of states of suffering such as fear, frustration, and pain. It might also be possible to use social interactions as indicators of welfare. The possibility of using "luxury" behavior, such as play and exploratory behavior, as an indicator of positive emotional states, requires investigation. Important welfare consequences arise from the fact that some behavior may be so strongly motivated as to constitute a "need". A behavioral need will arise in the case of behavior, such as nesting, that is controlled largely by internal factors, because these factors will be present no matter what type of environment is provided. Behavior triggered largely by external stimuli, such as responses to predators, will not give rise to a need if the external factors can be removed from the environment. Dustbathing is an example of behavior controlled by complex interactions between internal and external factors; the extent to which this constitutes a need is still being debated. If a behavioral need arises, then it is important that the environment provided allows it to be performed without damage to the performer or other birds. It should also be remembered that birds may need to perform behavior, including appetitive as well as consummatory elements, although the functional consequences of these are no longer required for survival. Finally, the performance of certain behavior leads to an increase in health or physical condition that improves welfare later in life.     

祥光“双闪”上升烟道出口粘接控制实践

闪速炉上升烟道出口粘接是闪速炉行业共同面对的问题,祥光采用"双闪"技术,上升烟道出口的结构不同于国内其它闪速炉,尤其是吹炼炉上升烟道出口粘接的控制在国内更是没有先例。最初的控制采用爆破法,由于缺点较多,严重影响闪速炉作业率,后来逐步试验通过局部过热的方法控制,通过调整天然气燃烧量或加入粉煤量消除粘接,通过一年多的试验证明局部过热法是解决此问题的最好办法,大大提高了"双闪"的作业率。

Learning in a changing environment.

Multiple cue probability learning studies have typically focused on stationary environments. We present 3 experiments investigating learning in changing environments. A fine-grained analysis of the learning dynamics shows that participants were responsive to both abrupt and gradual changes in cue–outcome relations. We found no evidence that participants adapted to these types of change in qualitatively different ways. Also, in contrast to earlier claims that these tasks are learned implicitly, participants showed good insight into what they learned. By fitting formal learning models, we investigated whether participants learned global functional relationships or made localized predictions from similar experienced exemplars. Both a local (the associative learning model) and a global learning model (the Bayesian linear filter) fitted the data of the first 2 experiments. However, the results of Experiment 3, which was specifically designed to discriminate between local and global learning models, provided more support for global learning models. Finally, we present a novel model to account for the cue competition effects found in previous research and displayed by some of our participants.
