The triggers of local and distant search: Relative magnitude and persistence in explaining acquisition relatedness

Research on problemistic search has assumed negative attainment discrepancy to be the trigger of both local and distant search. Extending this research, we present and compare two additional triggers: (1) relative attainment discrepancy, which reflects how much a firm's attainment discrepancy deviates from its past negative attainment discrepancies; and (2) persistent attainment discrepancy, which reflects how often the firm experiences below-aspirations performance. Our triggers for distant search model a behavioral explanation for the timing and relatedness of acquisitions. We find support for baseline arguments of problemistic search whereby firms increase both industry- and skill-related acquisitions when they perform below aspirations. When they persistently perform below aspirations, however, this likelihood is reduced and firms engage in acquisitions that are more unrelated, thereby providing support for the notion of expanding search boundaries from local to distant search. Of the two triggers of distant search proposed, relative attainment discrepancy does not induce firms to expand search boundaries. Our results indicate that persistent attainment discrepancy is a key construct to consider when studying the expansion of search boundaries.     

论洪仁玗中西文化观之特色

洪仁接受了中西文化并皈依上帝 ,其文化观具有浓厚的宗教色彩。他既有对西方文化多方位接受和认同的趋新意识 ,又有对传统文化的恋旧情结 ,试图用附会中西的办法来规范中西文化。他的文化观极具开放性和前瞻性 ,但又有自相矛盾和不成熟的局限     

Using local linear kernel smoothers to test the lack of fit of nonlinear regression models

Herein, we propose a data-driven test that assesses the lack of fit of nonlinear regression models. The comparison of local linear kernel and parametric fits is the basis of this test, and specific boundary-corrected kernels are not needed at the boundary when local linear fitting is used. Under the parametric null model, the asymptotically optimal bandwidth can be used for bandwidth selection. This selection method leads to the data-driven test that has a limiting normal distribution under the null hypothesis and is consistent against any fixed alternative. The finite-sample property of the proposed data-driven test is illustrated, and the power of the test is compared with that of some existing tests via simulation studies. We illustrate the practicality of the proposed test by using two data sets.     

欧洲社会文化与欧洲统一运动

古希腊、罗马文化与基督教欧洲化引起欧洲社会的几次大转型，形成了泛欧社会文化传统；这个传统在文艺复兴时期被现代欧洲民族主义文化所取代而退隐。这个退隐的社会文化传统促使战乱不息的欧洲社会以统一运动的形式，开始其新的大社会转型性整合。今日欧盟正是这种社会文化转型的体现。     

风险投资与地方政府财政的作用定位

发展风险投资是推动高新技术产业加快发展、实现产业结构优化升级的重要途径。鉴于风险投资业在我国刚刚起步的现实 ,强调地方政府介入风险投资意义重大。近期地方政府介入风险投资应在资本配置中发挥重要作用 ;从长远来讲 ,地方政府应致力于相关制度环境建设 ,这方面的内容包括政策引导、制度环境支持以及法律保障等 ,以此创造有利于风险投资业大发展的社会环境     

论文化链接下的语言研究

“文化——语言”研究是一种立足于语言学而又导入了文化因素的语言研究方式,故称为文化链接下的语言研究。本文分析了这种语言研究方式的类型及主要研究方法,并且在对以往的“文化——语言”研究进行评价的基础上,提出对这项研究的深层思考。     

人类学视角:文化调适的相对性——对华北农业可持续发展的再思考

文化的调适使人类能够在演化过程中生存,并在不同的环境中扩张。但文化的调适在特定的环境里具有相对性:文化在某一系列环境中是适应的,或在短时期内是适应的,却在另一系列环境中是不适应的,或在长时期内是不适应的。从文化人类学的角度,回顾与探讨华北地区农业文化调适环境的状况以及存在的非生态的文化调适,重新思考华北农业可持续发展的定位。     

提高我国文化软实力的意义与对策

文化软实力是综合国力和国际竞争力的重要组成部分,我国要在激烈的国际竞争中赢得主动,就必须使国家文化软实力有一个大的提高。为此,要构建社会主义核心价值体系,努力提高国民综合素质;加强文化交流与传播,提高中华文化的渗透力;推进文化创新和文化体制改革,充分发掘中华传统文化的优势;在公共文化服务体系建设中,加强基层文化建设,以城市社区文化建设和农村文化建设为落点;建立产品丰富、门类齐全、结构合理、运行规范的文化市场体系,运用高新技术创新文化生产方式,培育新的文化业态,加快构建传输快捷、覆盖广泛的文化传播体系。     

The Perceptions of Women’s Roles and Progress: A Study of Malay Women

This study examines the general perceptions of women towards their roles, their interpretation of progress, as well as the facilitating factors and barriers to their progress. Questionnaires were distributed to 1,000 Malay women in Malaysia from rural and urban areas, from various age and income groups. Interviews were also carried out on the selected sample. Using both quantitative and qualitative methods of analyses, the results showed that women were perceived to play a strong, influential, and supportive role in their families. The results also showed how women perceive progress. These findings are discussed in relation to culture, socialization, values and norms of the Malay society.     

大学生言语失范的表现、成因及其应对措施
