目的:探讨血清抑制素B(INHB)、窦卵泡数检测值在预测高龄不育妇女卵巢储备功能方面的临床价值。方法:检测50例年轻健康人群中月经正常的育龄妇女及50例高龄不育妇女血清抑制素值,采用(经阴道和腹部联合)超声检查方式对所有研究对象卵巢的体积、窦卵泡数、卵巢皮质血流情况进行测量,对卵巢储备功能进行监测。结果:血清中抑制素水平检测值正常妇女组为(71.12±29.23)pg/ml,高龄不育组为(13.67±9.23)pg/ml,统计学分析示两组间有显著性差异。正常组窦卵泡数>15,高龄不育组<10,两组比较亦有统计学意义。结论:INHB水平是反映卵巢储备功能的直接指标,较促卵泡成熟激素(FSH)、E2和FSH/LH(促黄体激素)比值更早期、更敏感;对预测卵巢储备功能具有一定的临床价值。窦卵泡计数也是反映卵巢储备能力的一项重要指标。 相似文献

《Food Policy》2014
Multilayered conformity-assessment systems (MCASs) are becoming an increasingly prominent governance mechanism in food and agriculture. MCASs maintain their legitimacy through the use of scientific norms and practices, as well as multiple tiers of oversight. The purported outcome is standardized conformity-assessment practices, and thus, standardized food and production practices regardless of location or producer. This article examines the ability of MCASs to enforce one form of zero tolerance standards: organics (i.e., zero-synthetic chemicals). The focus is on the governance of organic standards in the rural Indonesia, where the idea of zero tolerance is historically foreign. Drawing on a case study of an organic shrimp project in Indonesia, the ways that the social, economic, and cultural conditions of the global South affect the operations of a MCAS and the capacity of the MCAS to adapt to such conditions are examined. My findings raise questions as to the capability of MCASs to ensure standardized food governance globally. 相似文献

The growth and survival of international new ventures (INVs) has not been the subject of extensive in-depth qualitative study and our understanding of their decision-making is deficient. On the basis of empirical analyses in a small and open economy, a dynamic model was developed that explains the growth phases through which INVs pass as they mature in the high-technology business-to-business field. The model also recognizes rapid advancement, survival crises, and retrenchment. Propositions were devised regarding the impact of opportunities, resources and capabilities, entrepreneurial orientation, and learning on growth phases and survival. A novel finding is that the decision-making logic moderates the impact of these factors. These findings have important implications for industrial marketing scholars and practitioners. 相似文献

由于人民币持续升值、金融危机影响、外贸竞争加剧等原因,我国诸多外贸型服装企业启动了内销战略,但面对越来越成熟、竞争同样激烈的服装内销市场,从外销进军内销是希望与风险并存。涉足内销的外贸型服装企业,应该突破传统的渠道模式,以渠道扁平化为基点,挺进国内市场。 相似文献

成长性、成熟性和衰退性产业上市公司并购绩效的实证分析 总被引:51,自引:0,他引:51
按照并购双方行业的相互关系,并购可以分为横向并购,纵向并购和混合并购。本文认为,公司所处产业的性质(成长性,成熟性,衰退性)在很大程度上影响着不同类型并购的绩效,处于不同性质产业的公司进行不同类型并购后的绩效不同,利用我国上市公司1995-1999年336次并购事件进行实证分析的结果表明;处于成长性行业的公司进行横向并购绩效相对最好;处于成熟性行业的公司进行纵向并购绩效相对最好;处于衰退性行业的公司进行横向并购的绩效最差。 相似文献

为了使军队工程招投标适应我国招投标的发展趋势,提高我军工程建设的投资效益,探讨经评审的最低投标价法在军队工程中的推广应用具有重大意义。在对军队工程招投标存在问题分析的基础上,探讨了这种评标方法应用的必要性和可行性。提出了具体的做法和相关的建议,即评标过程的一体化管理思想和10个关键环节的管理。分析了这种评标方法难以推广的原因和军队应采取的对策。通过分析,认为在军队工程中推广使用经评审的最低投标价法的条件已经成熟,这种方法将会在军队工程建设中发挥越来越重要的作用。 相似文献

国内外有关矿区预警的研究方兴未艾,国内外专家、学者关于矿区预警机制的涵义、价值观、地位、作用以及生态文明建设等重要领域开展了卓有成效的研究,并取得了重要的研究成果。但关于矿区生态预警的研究至今尚未形成成熟、系统的理论和方法,矿业的特殊战略地位及当前生态文明研究的重要性,决定了这一领域的理论和方法,具有明显的理论价值和实践意义,并具有相当的研究价值和潜力。鉴于此,本文对预警理论也提出了相关的理论视角,以期丰富该理论的深度。 相似文献

在棉纤维成熟度的指标中,棉纤维的成熟系数和成熟度比,反应的是棉纤维个体的成熟情况,两者之间可以用数学关系式进行表达;成熟纤维百分率反映的是棉纤维集合体的成熟情况,不能由一根棉纤维的成熟情况描述全部纤维集合体的成熟情况;成熟系数、成熟度比与棉纤维成熟纤维百分率之间的关系不确定,不存在必然的数学关系式。 相似文献

The need to coordinate multinational R & D increases in many corporations which want to take advantages of scale, synergy and multinationality on a world-wide basis. The Swedish engineering corporation SKF has tackled this problem as an early internationalized but lately diversified corporation working in mature technologies and markets. Substantial coordination has been achieved through a heavy resource commitment in a foreign corporate R & D lab, and a subsequent build-up of a rather elaborate system for R & D management throughout the corporation. The structure and processes of the system are described, together with experiences of coordinating effects, and a project case is given. The chosen mode of coordination is finally compared with situations in other industries. 相似文献

The Spirituality of Innovation: Learning from Stories 总被引:1,自引:0,他引:1
Sooner or later, most established companies face a mid-life crisis. Just like many people, these companies somehow lose the drive, the excitement, and the enthusiasm of their youth. Rather than continue to push the envelope, these companies focus on their core competencies and try to maintain order through a proliferation of policies and procedures. On the other hand, some companies (and some people) manage to sustain their innovative, entrepreneurial spirit. A handful of mature companies somehow maintain an environment in which employees continually generate added value for customers and the company alike. How do they do it? How do these mature companies continue to foster invention and innovation? Recognizing that stagnation and decline are not faits accomplis for all companies, Karen Anne Zien and a cross-functional team conducted in-depth interviews at several highly innovative firms. The interviewees provided insight into the culture, the characteristics, and the principles that set these companies apart from the competition. Perhaps the greatest insight comes from the stories these people tell. These war stories—the corporate myths and legends—provide a simple means for communicating and reinforcing the shared values that distinguish these companies. For example, a manager's recollection of Hewlett-Packard's effort to develop a pen plotter (and in particular, Bill Hewlett's role in this development) demonstrates that innovation is a companywide activity that requires the active, ongoing involvement of leaders at the highest levels of the organization. Senior people in these innovative companies foster a sense of community and common purpose and thus create an environment that encourages employees to explore new ideas and, if necessary, break the old rules. Through both formal and informal means, these companies also encourage frequent interaction between technical and marketing people. Corporate leaders energize these mature, but still innovative, companies, by providing context and communicating a dynamic vision. Storytelling offers a particularly evocative medium for articulating this vision. Rather than bore newcomers with hoary tales of the good old days, however, the most effective leaders continually reshape these stories to offer fresh insights, uncover new challenges, and reinforce the notion that every employee can and should contribute their full potential. 相似文献
