高职院校学生的生育道德观现状与实证研究

研究分别以分层丛集式问卷与子女价值量表对24岁以下的高职学生进行生育道德观的实证分析,旨在探讨生育道德观与未来希望生育子女数及生育挟择的整体关系。结果发现：高职学生以“权力成就”、“亲密情感”、“家庭愉悦”为最主要的认同层面;生育道德观因性剐、交友情况、父母教育程度等成长经验的不同而有所差异;生育道德观中“生育价值”、“生育代价”、“生育挟择”因素对未来希望生育子女数有一定程度的预测力。     

All for one or one for all? Authorship and the cross-sectoral valuation of credit in nutrition science

The passionate pursuit of authorships is fuelled by the value they represent to scholars and scientists. This article asks how this value differs across scientists and how these different processes of valuation inform authorship articulation, strategies, and publication behavior in general. Drawing from a qualitative analysis of authorship practices among nutrition scientists employed at universities, contract research organizations, and in food industry, I argue that two different modi operandi emerge when it comes to authorship. These different ways of working produce different collaborative approaches, different credit distribution strategies amongst collaborators, and different value placed upon (the pursuit of) authorship. These different valuation processes are neither explicit nor recognizable to those reading (and judging) author lists. As a consequence, in the politics of authorship, the names standing atop a scientific publication in nutrition science represent different types of value to both the individuals and employing organizations.     

诸神之争的再阐释:一个社会学的结构视角

世俗化及逆世俗化范式的对立其实蕴含着更大的连续性,即如何理解宗教多元主义背后的诸神之争,总的来说,韦伯之后那些解释宗教变迁的理论范式均未突破韦伯对宗教的比较研究范畴,难以在当前复杂而多元的文化环境下为个人提供总体指导,但是二者共同揭露了诸神之争条件下西方宗教工具理性和价值理性交互作用所促成的理性化的动力机制,即西方宗教维护自身价值理性的方式从中世纪教会主导的政治性垄断过渡到现代性条件下宗教多元主义的市场化竞争。     

Perceptions of grandparents who provide auxiliary care: value transmission and child‐rearing practices

A grounded theory qualitative study was developed to explore how grandparents perceive their role as socializing agents. Forty‐two grandparents with grandchildren aged from 6 to 12 years old participated in this study. Data were collected through focus groups, which were conducted until reaching data saturation and analyzed using the constant comparative method. Four general conclusions emerged from the study: (i) grandparents recognized the importance of getting involved in the socialization of grandchildren as supporters of parents' socializing role, and the need to adapt to social changes; (ii) they emphasized traditional value that were perceived in decline, and combination of warmth and involvement were considered the best way to help grandchildren internalize values; (iii) interaction with grandchildren helped grandparents to feel active and useful, increased their life purpose and gave them a second chance to enjoy what they could not with their own children; and (iv) grandparents also accused burden and role ambiguity. These results show the importance of developing family policies that recognize grandparents' socializing role. Also, interventions that promote strategies that enable grandparents to perform their role more successfully and to cope with possible family conflicts should be developed.     

A social welfare perspective of market‐oriented social enterprises

The article analyses market‐oriented social enterprises from a social welfare perspective, within the context of the innate conflict between business and welfare orientations. After defining the concept of market‐oriented social enterprises and presenting some successful examples on such entities that employ different marginalised populations, particularly people with disabilities, the article asks three interrelated questions: (i) What policy environment is needed to encourage the development of social enterprises? (ii) Given the innate tension between the social and economic objectives in social enterprises, what structural principles are needed to enable them to meet those dual objectives? Lastly, (iii) What intervention modalities are best suited to help individual participants in those frameworks? Answers to these questions are discussed within conceptual frameworks from the worlds of welfare and business that jointly provide a base for a social welfare rationale for market‐oriented social enterprises.     

Monitoring the parameter vector of regression models with time-to-event response in phase II processes

In most of the existing specialized literature, monitoring regression models are a special case of profile monitoring. However, not every regression model always represents appropriately a profile data structure. This is clearly the case of the Weibull regression model (WRM) with common shape parameter γ. Even though it might be thought that existing methodologies (especially likelihood-ratio (LRT)-based methods) for monitoring generalized linear profiles can also be successfully applied to monitoring regression models with time-to-event response, it will be shown in this paper that those methodologies work fairly acceptable just for data structures with 1000 observations at least approximately. It was found out that some corrections, often referred to as Bartlett's adjustments, are needed to be implemented in order to improve the accuracy of using the asymptotic distributional properties of the LRT statistic for carrying out the monitoring of WRM with relatively small and moderate dimensions of the available datasets. Simulation studies suggest that the use of the aforementioned corrections make the resulting charts work quite acceptable when available data structures contain 30 observations at least. Detection abilities of the proposed schemes improve as dataset dimension increases.     

Objective Bayesian analysis based on upper record values from two-parameter Rayleigh distribution with partial information

In the life test, predicting higher failure times than the largest failure time of the observed is an important issue. Although the Rayleigh distribution is a suitable model for analyzing the lifetime of components that age rapidly over time because its failure rate function is an increasing linear function of time, the inference for a two-parameter Rayleigh distribution based on upper record values has not been addressed from the Bayesian perspective. This paper provides Bayesian analysis methods by proposing a noninformative prior distribution to analyze survival data, using a two-parameter Rayleigh distribution based on record values. In addition, we provide a pivotal quantity and an algorithm based on the pivotal quantity to predict the behavior of future survival records. We show that the proposed method is superior to the frequentist counterpart in terms of the mean-squared error and bias through Monte carlo simulations. For illustrative purposes, survival data on lung cancer patients are analyzed, and it is proved that the proposed model can be a good alternative when prior information is not given.     

Asymptotic expansions of density of normalized extremes from logarithmic general error distribution

Logarithmic general error distribution is an extension of the log-normal distribution. In this paper, the asymptotic expansions of densities of normalized maximum from logarithmic general error distribution are derived under two different kinds of normalized constants. By applying the main results, the higher-order expansions of moments of maxima are established.     

The Chinese Cashmere Industry: A Global Value Chain Analysis

Growth and internationalisation of the Chinese economy have reconfigured the global value chains of many commodities with important implications for industry and rural and regional development both in and outside China. This article analyses the chain for cashmere, all stages of which have gravitated to China, and the impacts on rural development, especially for herders in remote pastoral regions. Traditionally a high‐value product, cashmere has become increasingly generic and adulterated over the past decade. More formal and closer integration of Chinese actors into the global industry and re‐orienting policy from supply‐side intervention to the enforcement of standards would enhance the competitiveness of Chinese cashmere in international fibre markets.     

生态价值:基于马克思劳动价值论的一个引申分析

检视和比较中西方关于生态价值问题的研究文献,基于马克思劳动价值论,并将其引申扩展到探索生态价值的致思路径是:沿着人类社会生产力发展水平不断提升的线索,从经济系统、生态系统和生态经济系统考察商品总价值、生态总价值和商品价值总量之间的内在关联及其数量变化关系。随着人类社会生产力水平由低到高的提升,商品总价值、生态总价值和商品价值总量三者之间呈现由同向递增变动到无序变动、再到更高层次的同向递增变动的趋势。在中国当前经济社会发展面临严峻生态问题的状况下,重新认识和理解生态价值问题,将有利于改变当前衡量经济社会发展指标过度单一的局面,有利于转变人们对自然生态资源、生态环境的不合理开发和利用的传统发展理念,有利于有效推动自然资源定价和参与市场化治理,并为其提供理论基础,从而使自然生态环境能够被科学、合理、协调、可持续地开发和利用。
