摘要：合资企业是发展中国家企业组织学习和知识获取的重要途径。本研究运用国际合资企业管理控制和组织学习理论,探讨了中方对合资企业的管理控制如何影响不同类型知识的获取,并分析了学习能力和合作信任对于管理控制与知识获取之间的调节作用。本研究发现中方对合资企业的运营控制程度降低了中方的内隐知识和外显知识获取水平;在均等股权的合资企业中,中方知识获取的水平最高;合作信任对于管理控制与知识获取之间关系存在调节作用。 相似文献

知识链组织间的关系不协调将会引起知识链组织之间的冲突.由于知识链组织之间冲突的复杂性、非线性、不确定性等特性,导致无法用精确的数学模型来表述.而专家系统作为人工智能的一种方法,在处理这类问题上具有优势,为此设计了以案例推理和理论规则推理两级推理机制为主体的冲突管理专家系统,以期为知识链组织之间冲突管理提供一种新的思路和方法. 相似文献

科学管理中工人所拥有的具有个体性、稳定性、难以流动性等特征的隐性知识,让磨洋工在生产劳动中成为可能。为了消除工人各种形式的磨洋工现象以提高工人劳动生产率,泰罗通过动作研究、工时研究以及工具研究等科学研究手段,将那些隐藏在工人个体身上的隐性知识转化为经过简单培训就可以学会的显性知识,藉此实现了管理的科学化、劳动生产率的提高、劳资双方的富裕以及生产过程控制权的顺利转移,终结了工匠控制,开启了管理控制,推进了资本主义从工匠资本主义向管理资本主义转换的进程,实现了美国社会的和谐。 相似文献

Although often downplayed and instrumental, there is evidence that communication in projects is essential in achieving value creation. Our main interest in this paper is on temporary continuity, a situation where the temporary becomes a permanent condition in social systems. The question that we have address is: What characterizes project communication in a situation with temporary continuity?We argue for the need to transform communication processes into communication capabilities. In a situation with temporary continuity, there is a need to connect to a large number of value-creating processes, and communicating capabilities need to be a part of a communication system, where the aim is to bind together value-creating processes and communication capabilities. We construct a viable system consisting of five sub-systems. To become a viable system, projects in the form of temporary continuity, must handle the potential conflict between a culture of performance and a culture of innovation. This involves developing social mechanisms for coordination and interaction, with a focus on developing communication capabilities, in parallel with focusing on all of the five value-creation processes. 相似文献

在以企业为主要表现形式的工程活动共同体中,作为其成员的个体各自占据一定的岗位而发挥其作用,每个个体都是＂本位人＂和＂岗位人＂的统一。文章着重分析了作为＂个体＂的个人和作为＂集体＂的工程共同体的动态关系。个体通过招聘过程而在工程共同体中＂出场＂,然后是在工作岗位起作用的＂在场＂和离开工程共同体的＂退场＂。文章最后部分运用中国哲学的阴阳理论对人性问题和本位人和岗位人的相互关系进行了简要分析。 相似文献

物质是原子的宏观集合,原子是物质的基本单位,因为原子是单个存在的,那么物质就是不连续的,是量子化的,所以物质只不过是一堆原子按照一定的逻辑顺序（即信息,而这种信息就是电磁波）不连续地堆积起来,又具有一定能量的产物,而且从量子力学来看,物质在下一秒会以什么状态出现在什么地方,也是无法完全确定的。那么直线更是人们思维意识中的幻想,现实中根本不存在的实物中的直线。 相似文献

Prostate specific antigen is considered to be a tumour marker having maximum utility and specificity for prostate cancer since decades. After the discovery of methods to quantify different molecular fractions of prostate specific antigen (PSA), its usefulness in diagnosing early prostate cancer cases has increased tremendously. The “specificity” of PSA, is now challenged by many studies which proved that PSA, once believed to be secreted exclusively by prostatic epithelium, is also present in females. The exact biological role of extraprostatic PSA is still debatable though many theories substantiated by in vitro evidence has been put forward. With the advent of ultrasensitive analytical techniques, PSA is now quantifiable in female serum in its various molecular forms and this has led to many assumptions of it being useful as a marker in female breast cancers. In a similar scenario to prostate cancer, the ratio of free to total PSA is shown to be useful in detecting early breast cancer cases. It is also shown to be a good prognostic indicator and a predictor of response to therapy and recurrence. Apart from its role in breast cancer, it has been advocated to be a marker of hyper androgenic states in women like hirsutism and polycystic ovarian syndrome. Conflicting reports regarding the role of extra prostatic PSA is accumulating but it has been proven beyond doubt that PSA is no longer specific and confined to prostate gland. Various studies have registered that PSA is an ubiquitous molecule, secreted by hormone responsive organs and its synthesis is stimulated by androgens and progesterone but not oestrogens. In this article, a review of various literatures is done about the presence of extra prostatic PSA, its probable role in those sites as well as its utility as a tumour marker in breast cancer. 相似文献

语文课是充满生机和活力的课堂。语文课往往并不呈现出一种静态的知识体系,而是与师生一起处于一种变动的关系之中。语文课是预设与生成的统一。一节好的语文课应该更重视生成。叶圣陶先生说：＂语文教本只是些例子。＂这就对语文教师提出了更高的要求,它要求教师不仅是语文教科书的执行者,也应该是教科书的改造者、创新者。对于课堂的主人——学生来说,教科书也仅仅是有待激活的原声材料,它要在教师的引领和学生的理解中生成符合学生认知规律的知识。只有通过师生的感悟、体验、理解,教科书才能发挥它内在的精神意蕴和包含的文化精神。 相似文献

Chunking is a task which divides a sentence into non-recursive structures. The primary aim is to specify chunk boundaries and classes. Although chunking generally refers to simple chunks, it is possible to customize the concept. A simple chunk is a small structure, such as a noun phrase, while constituent chunk is a structure that functions as a single unit in a sentence, such as a subject. For an agglutinative language with a rich morphology, constituent chunking is a significant problem in comparison to simple chunking. Most of Turkish studies on this issue use the IOB tagging schema to mark the boundaries.In this study, we proposed a new simpler tagging schema, namely OE, in constituent chunking for Turkish. “E” represents the rightmost token of a chunk, while “O” stands for all other items. In reference to OE, we also used a schema called OB, where “B” represents the leftmost token of a chunk. We aimed to identify both chunk boundaries and chunk classes using the conditional random fields (CRF) method. The initial motivation was to employ the fact that Turkish phrases are head-final for chunking. In this context, we assumed that marking the end of a chunk (OE) would be more advantageous than marking the beginning of a chunk (OB). In support of the assumption, the test results reveal that OB has the worst performance and OE is significantly a more successful schema in many cases. Especially in long sentences, this contrast is more obvious. Indeed, using OE means simply marking the head of the phrase (chunk). Since the head and the distinctive label “E” are aligned, CRF finds the chunk class more easily by using the information contained in the head. OE also produced more successful results than the schemas available in the literature.In addition to comparing tagging schemas, we performed four analyses. Along with the examination of window size, which is a parameter of CRF, it is adequate to select and accept this value as 3. A comparison of the evaluation measures for chunking revealed that F-score was a more balanced measure in contrast to token accuracy and sentence accuracy. As a result of the feature analysis, syntactic features improves chunking performance significantly under all conditions. Yet when withdrawing these features, a pronounced difference between OB and OE is forthcoming. In addition, flexibility analysis shows that OE is more successful in different data. 相似文献
