在校期间降低临床医学专业毕业生再培养成本的研究

大学毕业生就业难,尤其是民办医学院校临床医学毕业生就业压力大,医生是非常高专的职业,医学生毕业以后要经过长时间的培训锻炼才能够独立的上岗,这需要耗费所在单位巨大的培养成本,本文对在校期间如何降低临床医学专业毕业生再培养成本进行了初步探讨,并初步总结了本次探讨的成效。     

顾及地形线的DEM的空间克里格内插法

将规则格网覆盖在离散数据高程点和地形特征线的分布图上,然后用内插技术产生高程矩阵。内插是生成规则格网的数字式地形表达模型的关键技术。因此,通过比较而选择一个合用的,适合于数据空间分布特点的内插方法(模型)是空间内插的关键。     

Effects of dominance transitions on advice adherence in professional service conversations

For many professional services, advice adherence is a necessary condition for achieving service success for both customers and service providers. Despite their pivotal roles in value co-creation, typical conversational interactions often lead to low adherence. We propose that enabling a “dominance transition,” from provider dominance in the pre-advice stage to customer dominance in the post-advice stage, enhances advice adherence because it increases customers’ perceived common ground. Furthermore, providers’ consultation focus, customers’ prior knowledge, and customers’ perceived adherence effort moderate this process. Using mixed methods, including both empirical modeling and controlled and field experiments, we validate the proposed model in various contexts (healthcare, financial services, and fitness and wellness counseling). The findings establish several theoretical contributions and offer managerial implications for improving advice adherence by managing dominance transitions in conversational interactions more effectively through training service providers or even programming AI chatbots.

     

中国上市企业并购的财务协同效应研究——聚焦于放大和紧缩

企业的并购是影响企业价值的重要经济活动,尤其是上市企业更是如此.研究以2006年发生的80起并购案例作为考察对象,首先通过计算差量来获取并购前一年、并购当年、并购后三年共计五年的财务时间序列数据;并采用差值分析方法分别对同业并购和混业并购所获得的财务协同效应进行比较,在通过有效性检验和主成分分析对财务协同效应的影响因素的基础上构建了主成分综合模型.研究得到的结论是:短期来看,我国上市企业并购的的财务协同存在着一种放大效应,但长期则显现出了财务协同的紧缩效应;长期看来同业并购资本使用效率上的放大效应更加能明显地持续下去;在偿债能力的放大效应上,短期内混业并购要优于同业并购,但在后期同业并购仍然要好于混业并购.所以我国企业在采取并购时,应该充分考虑自己的战略和并购目标,如果公司期望通过并购来提高自身的资本使用效率,采取混业并购战略更能达到这个目的;如果希望通过并购来进行业务的整合和扩张,那么企业应该采用同业并购的战略.     

试论农业科技发展的规律性

本文从逻辑和历史相结合的角度,论述了农业科技发展作为一个过程所具有的三个方面的规律性,即：①生活资料需求、生产资料需求、生态环境需求和社会文化需求等多样化的社会需求是推动农业科技发展的主要动力;②清除或缓解生产要素配置中的“瓶颈”制约,是农业科技发展的突破口;③提高由社会生产力和自然生产力构成的农业生产力的整体水平,是它业科技发展的落脚点。     

A Brief Survey of Modern Optimization for Statisticians

Modern computational statistics is turning more and more to high‐dimensional optimization to handle the deluge of big data. Once a model is formulated, its parameters can be estimated by optimization. Because model parsimony is important, models routinely include non‐differentiable penalty terms such as the lasso. This sober reality complicates minimization and maximization. Our broad survey stresses a few important principles in algorithm design. Rather than view these principles in isolation, it is more productive to mix and match them. A few well‐chosen examples illustrate this point. Algorithm derivation is also emphasized, and theory is downplayed, particularly the abstractions of the convex calculus. Thus, our survey should be useful and accessible to a broad audience.     

Housing Preferences of Temporary Migrants in Urban China in the wake of Gradual Hukou Reform: A Case Study of Shenzhen

In the wake of the recent announcement by the State Council concerning the provision of public rental housing across China, and the gradual reform of China's household registration system (hukou), this article explores how potential adjustments in government housing policies (namely access to public rental housing) influence the housing preferences of temporary migrants who are currently residing inside the chengzhongcun (urban villages) of Shenzhen. The results indicate that dissatisfaction with rental cost and living conditions in these urban villages are the key reasons for migrants wishing to move into public rental housing if it is offered to them — and not the fact that they are treated differently within the hukou system. Public rental housing is welcomed in particular by newly arriving migrants who live outside the Shenzhen Special Economic Zone (SEZ), and migrants who have decided to remain in Shenzhen for the foreseeable future. By contrast, dissatisfaction with urban villages is the sole contributor to housing preferences for those residing inside the SEZ.     

Política de la legislación laboral en el sur de China. Las cámaras de comercio y otros organismos extranjeros ante las leyes sobre negociación colectiva

En 2010, tras la huelga en Honda, hubo protestas laborales en toda China. Los gobiernos de Shenzhen y Guangdong reaccionaron desempolvando los proyectos de Decreto sobre consulta colectiva y de Normativa sobre gestión democrática de las empresas, retirados con anterioridad. Pero tras la oposición frontal de cámaras de comercio y organismos gubernamentales extranjeros, hongkoneses y taiwaneses, volvieron a retirarse. Mediante entrevistas, los autores revelan los medios de influencia en la legislación laboral china de estos actores, cuyas actitudes dependen de la posición de las empresas representadas en las cadenas mundiales de producción y del modelo de relaciones laborales de su país o territorio de origen.     

地方政治权力转移与企业社会资本投资周期--基于政企关系重构的动态研究

文章以2007－2012年我国A 股上市公司为样本,从政企关系重构的视角研究了地方政治权力转移对企业社会资本投资的影响。研究发现：(1)在地方政治权力转移当年,企业会显著提高社会资本投资力度。随着主政官员任期的增加,企业社会资本投资呈现下降趋势。这说明在主政官员任期内,企业社会资本投资呈现先增后减的周期性特点。这种周期性特点仅在民营企业中存在。(2)民营企业社会资本投资的周期性特点在地方官员来自外地、继任官员预期任期较长、管制行业以及融资约束程度高和无政治关联的企业样本中更加显著。(3)在地方政治权力转移当年,民营企业提高社会资本投资力度能够帮助其获得政府补助,但这种优势并不会立刻体现出来;同时,企业提高社会资本投资力度也会对自身的研发投入产生挤出效应,且挤出效应持续存在于继任官员的整个任期中。文章的研究为理解企业建立政企关系的手段、过程与效果提供了新的视角。
