以学习力构筑学习型组织的生态链——JAC学习型营销体系的思考和初探 总被引:1,自引:0,他引:1
世界经济全球化和新经济的兴起,正改变着企业营销环境。国内市场国际化和国际竞争国内化已成为不可逆转的发展趋势。市场竞争的激烈化和复杂化、顾客需求的个性化和多样化使更多的企业意识到仅靠单个企业单打独斗已难以取得持久的竞争优势。企业必须摒弃传统的营销观念和营销模式,重新认识和调整与相关企业的关系,积极营造相互竞争和合作的生态环境。有专家预言:未来的竞争将不再是单个企业之间的竞争,而是会演变为不同企业群落之间的竞争。 相似文献

"脑死亡"的价值与挑战 总被引:6,自引:0,他引:6
欧阳康 《华中科技大学学报(社会科学版)》2004,18(1):54-58
脑死亡是由当代科学和医学技术进步给我们带来的一个全新问题,也涉及到复杂的经济、社会、伦理和法律等问题。脑死亡的提出意味着对于生和死的判别由经验转向了科学;凸显了大脑和心脏在人的生命系统和自我认同中的不同地位。在相当长的时期内,对于大多数社会成员来说,脑死亡标准不一定意味着对于心死亡标准的截然取代。而是将与其并存。脑死亡的实施提出了抢救生命的价值、代价和极限问题,将对生命终结标准的选择权和宣判权提出挑战,也将对人们通常的“孝”和“敬”等观念提出挑战。脑死亡的一个重要价值是有利于器官移植,而让生命以此种方式得以延续值得提倡。因此应当以一种更加开放的和进步的心态来积极推进有关脑死亡的立法。 相似文献

The term mismatch problem in information retrieval is a critical problem, and several techniques have been developed, such as query expansion, cluster-based retrieval and dimensionality reduction to resolve this issue. Of these techniques, this paper performs an empirical study on query expansion and cluster-based retrieval. We examine the effect of using parsimony in query expansion and the effect of clustering algorithms in cluster-based retrieval. In addition, query expansion and cluster-based retrieval are compared, and their combinations are evaluated in terms of retrieval performance by performing experimentations on seven test collections of NTCIR and TREC. 相似文献

ABSTRACTHearken is a proprietary news engagement platform growing in popularity. Under the Hearken approach, audience members are invited to participate in the newsmaking process. Hearken strives to assist news organizations in providing local and hyperlocal content that meets audience needs and demands while preserving elements of the journalist’s role as gatekeeper. Hearken has also worked to help news organizations reach underrepresented populations with mixed results per its own anecdotal analyses. This study employs a quantitative content analysis comparing one year’s worth of coverage at four different local NPR affiliates in the United States to provide a breakdown of Hearken content versus traditional reporter-driven content in the following four categories: emphasis on hyperlocal coverage, story topic prevalence within local and hyperlocal coverage, emphasis on coverage of underrepresented communities, and story topic prevalence within coverage of underrepresented communities. Findings reveal listener-driven Hearken content favors hyperlocal news on lifestyle issues while reporter-driven stories emphasize state-level governance and politics as well as local crime. These indicate a stark contrast between the content audiences want and that which journalists tend to report. The nuanced normative implications, possibilities and limitations of Hearken’s model of “deep participation” are addressed in some detail. 相似文献

In this article I critically examine the historical context of science education in a natural history museum and its relevance
to using museum resources to teach science today. I begin with a discussion of the historical display of race and its relevance
to my practice of using the Museum’s resources to teach science. I continue with a critical review of the history of the education
department in a natural history museum to demonstrate the historical constitution of current practices of the education department.
Using sociocultural constructs around identity formation and transformation, I move to the present with a case study of a
teacher who transforms the structure of science education in her classroom and school as a result of her identity transformation
and association with a museum-based professional education program.

OBJECTIVE: Child maltreatment has been linked to negative adult health outcomes; however, much past research includes only clinical samples of women, focuses exclusively on sexual abuse and/or fails to control for family background and childhood characteristics, both potential confounders. Further research is needed to obtain accurate, generalizable estimates and to educate clinicians who are generally unaware of the link between childhood abuse and adult health. The purpose of this project is to examine how childhood physical abuse by parents impacts mid-life mental and physical health, and to explore the attenuating effect of family background and childhood adversities. METHODS: We analyzed population-based survey data from over 2,000 middle-aged men and women in the Wisconsin Longitudinal Study using self-reported measures of parental childhood physical abuse, mental health (depression, anxiety, anger), physical health (physical symptoms and medical diagnoses), family background, and childhood adversities. RESULTS: Parental physical abuse was reported by 11.4% of respondents (10.6% of males and 12.1% of females). In multivariate models controlling for age, sex, childhood adversities, and family background, we found that childhood physical abuse predicted a graded increase in depression, anxiety, anger, physical symptoms, and medical diagnoses. Childhood physical abuse also predicted severe ill health and an array of specific medical diagnoses and physical symptoms. Family background and childhood adversities attenuated but did not eliminate the childhood abuse/adult health relationship. CONCLUSIONS: In a population-based cohort of middle-aged men and women, childhood physical abuse predicted worse mental and physical health decades after the abuse. These effects were attenuated, but not eliminated, by age, sex, family background, and childhood adversities. 相似文献

学术自由的大学本质观的应然诉求所产生的大学改革中的悖论,引发了人们对大学本质观的重新审视。对大学的内外环境进行分析及对大学发展历史与现实的考察可以看到,大学的本质是学术自由性与受控性双重属性的对立统一,这是一种基于对大学实然状态的分析所得出的全面辩证的大学本质观。这种大学本质观所揭示的学术自由性和受控性对立统一的矛盾运动,构成了大学存在与发展的根据和原因。处理好自由性与受控性的关系是推动大学改革发展的应然诉求。 相似文献
