“春秋笔法”与唐代小说叙事谋略探微

唐代尚史之风弥漫于文坛,造就了小说家特定的知识结构,从而赋予他们以突出的"史才";而许多唐代小说又多与当时的政治现实密切相联,为能自由地抒情言志、寄寓褒贬,于是源于历史叙事传统的"春秋笔法"便成为唐代小说家重要的叙事谋略."春秋笔法"的内涵为:作者不作论断,而是将自己的主观褒贬暗寓于客观冷静的叙事之中;叙事隐晦深曲,讲究匣剑帏灯、旁敲侧击.此二法在唐代小说中得到了充分显示.     

民族传统知识的法律保护初探

当前,我国民族传统知识的法律保护面临着相当严重的问题,《著作权法》、《文物保护法》、《商标法》、《专利法》等法律对民族传统知识的保护都不充分,存在诸多困难与不足。为此,我国应根据民族传统知识的特征,制定和完善保护民族传统知识的国内法和民族自治地方自治条例,在保护目的、权利主体和客体、内容、期限、侵权行为及其责任等方面做出明确规定,进而有力地保护与促进民族传统知识的正常利用和可持续发展。     

Leveraging the common and outsourcing the distinct: institutional difference and multinational company identity in emerging economies

ABSTRACT

This paper explores the challenges of outsidership faced by multinational companies (MNCs) accessing emerging economies. The paper departs from popular conceptualisations of culture drawing instead on social identity theory as part of an institutions-based view, to explain how employing a singularities approach can allow the identification of commonalities of Indianness and Australianness that can be leveraged to ameliorate negative socially embedded business norms that pose a challenge to MNC success in emerging economies. This study shows that despite recognised formal (regulatory) and informal (cultural) differences, managers of Australian MNCs operating in India were able to innovatively identify and exploit cultural commonalties/singularities to ease cultural adjustment and mitigate intergroup conflict, allowing them to achieve an innovative institutional fit. The paper discusses how, using this approach, sole-venture MNCs can access many of the benefits provided by collaborative entry modes while preserving MNC identity. We further propose that the singularities approach can provide a valuable starting point to develop culturally appropriate competence training initiatives.     

An improved alternative estimation procedure for current population mean in presence of positively and negatively correlated auxiliary variables in two-occasion rotation patterns

Abstract

The present study confirms the influential role of a positively and a negatively correlated auxiliary variables in enhancing the precision of estimates of current population mean in two occasion rotation (successive) sampling. Exponential-type estimators of current population mean have been proposed for three different situations: (i) the information on a positively correlated auxiliary variable is readily available on both occasions (ii) the information on a negatively correlated auxiliary variable is readily available on both occasions and (iii) the information on both positively and negatively correlated auxiliary variables are readily available on both the occasions. The characteristics of the proposed estimators have been explored and their efficacious performances are compared with the natural and recent contemporary estimators. Optimum replacement strategies of the proposed estimation procedures have been formulated. Simulation and empirical studies are carried out to justify the proposition of the proposed estimators and appropriate recommendations have been put forward to the survey practitioners.     

A visualization method measuring the performance of biomarkers for guiding treatment decisions

Biomarkers that predict efficacy and safety for a given drug therapy become increasingly important for treatment strategy and drug evaluation in personalized medicine. Methodology for appropriately identifying and validating such biomarkers is critically needed, although it is very challenging to develop, especially in trials of terminal diseases with survival endpoints. The marker‐by‐treatment predictiveness curve serves this need by visualizing the treatment effect on survival as a function of biomarker for each treatment. In this article, we propose the weighted predictiveness curve (WPC). Based on the nature of the data, it generates predictiveness curves by utilizing either parametric or nonparametric approaches. Especially for nonparametric predictiveness curves, by incorporating local assessment techniques, it requires minimum model assumptions and provides great flexibility to visualize the marker‐by‐treatment relationship. WPC can be used to compare biomarkers and identify the one with the highest potential impact. Equally important, by simultaneously viewing several treatment‐specific predictiveness curves across the biomarker range, WPC can also guide the biomarker‐based treatment regimens. Simulations representing various scenarios are employed to evaluate the performance of WPC. Application on a well‐known liver cirrhosis trial sheds new light on the data and leads to discovery of novel patterns of treatment biomarker interactions.

有限理性下的社保基金投资监管进化博弈研究

社保基金的投资监管是复杂的决策问题,无法满足主流博弈论“完全理性”的要求。因此从有限理性角度出发,分别建立了基金经理人之间、社保基金管理机构与基金经理人之间的进化博弈模型,求出模型的复制动态方程,研究不同情况下的进化稳定策略,并得到博弈群体的复制动态相位图。     

浙江省新生代农民工继续教育状况研究

中共中央、国务院印发的《新时期产业工人队伍建设改革方案》提出,要帮助"新生代农民工增加受教育培训机会,提高专业技能和胜任岗位能力",并将教育作为促进农民工融入城市,成为稳定就业的产业工人的重要路径。以浙江省11个地级市的服务行业、建筑行业、制造业的从业人员为主要调查对象,了解浙江省新生代农民工接受继续教育的现状与特点,发现新生代农民工存在自身接受继续教育的动力意愿不足、企业进行职业技能培训投资的动力意愿不足等问题,并据此提出要做好终身教育宣传、搭建继续教育平台、优化在职培训模式等解决办法。
