云南边疆少数民族间的"康吧"经济交往模式:理论与实证分析

"康吧"交往是纳西族与傈僳族、藏族之间一种独特而历史悠久的物质交换模式,它不符合理性选择的逻辑却能世代延续至今,同时,不同民族间的"康吧"交往又存在差异。本文借鉴西方主流理论对这种古老的交往模式进行分析,从经济学、社会学、人类学的多重理论角度出发,采用访谈、观察与定量分析相结合的研究方法,对上述现象进行了分析。研究结果表明:(1)资源依赖性、信任和互惠原则对"康吧"交往的延续至关重要;(2)货币市场和投机行为的出现导致"康吧"交往走向衰落,但情感互惠和资源互补使之至今存在;(3)自然资源条件、资源互补程度、社会历史背景和文化因素,对交往模式的差异都有重要影响作用。     

关于管理研究及其理论和方法的讨论

继续作者关于中国管理学科定位和发展方向的学术讨论,从管理学的研究动机,研究对象,以及理论和方法选择方面,讨论作者个人的一些初步想法.其基本观点主要有:1)学术研究的终极动力应该是对科学真理的追求;2)这种追求的一个重要特点就是勇于创新,勇于挑战现有的范式;3)这种创新必须基于严格的训练和严密的设计;4)这种严密的设计必须考虑到研究对象与理论和方法的匹配;5)中国管理学研究应该鼓励多种理论,多种学说,多种方法共同发展,取长补短,在借鉴国外主流管理学科发展的经验和教训的基础上,发挥中国管理学者的特长,解释和预测中国遇到的管理问题和现象,为整个管理学科的发展做出贡献.     

Judicious order acceptance and order release in make-to-order manufacturing systems

This paper explores a two-stage input control system for fixed capacity make-to-order manufacturing systems (with heavy job tardiness penalties), that selectively accepts incoming orders and holds the accepted ones in a pre-shop queue prior to releasing them to the shop floor. Single-stage input control systems that only allow orders to be delayed in a pre-shop queue (i.e. they do not allow some orders to be rejected) have been previously investigated and found to negatively impact overall due-date performance. The hypothesis motivating this research is that judiciously rejecting a subset of incoming orders can prevent the order release queue from being overloaded when a surge of demand occurs. The input control system is evaluated via experiments using a discrete-event simulation model of a fixed capacity manufacturing system. The experiments reported here suggest that holding orders in the pre-shop queue does not improve due date performance, and that judiciously rejecting orders on its own is a viable alternative mechanism of input control that can deliver improved performance.     

Individual Differences in Women's Salivary Testosterone and Estradiol Following Sexual Activity in a Nonlaboratory Setting

Objectives: The current study evaluated women's salivary testosterone and estradiol levels before and after exposure to sexual stimuli in a U.S. sex club. Methods: Behavioral data and salivary samples were collected from 19 women during semistructured interviews. Results: Findings demonstrate substantial individual differences in the magnitude and direction of women's hormonal changes following sexual activity. Conclusions: In an age of individualized medicine, these findings highlight the need to better understand factors shaping variation in physiological responses to sexual activity. Findings contribute to a relatively small and contradictory literature on women's hormonal responses to sexual stimuli.     

Original and Ongoing Dispossessions: Settler Capitalism and Indigenous Resistance in British Columbia

This paper draws on archival research and theoretical work to articulate the specific histories, processes, and structures of primitive accumulation in British Columbia. Such processes of accumulation appear differently here than in the comparably more well-theorized contexts of imperial colonialisms. As we highlight the agents and infrastructures of dispossession, our research also aims to foreground the importance of agents and infrastructures of resistance. Different dispossessions generate different antagonisms, and we argue that Indigenous subjects are situated antagonistically to capital not only as laborers partially or wholly subsumed into capitalist social relations, but as Indigenous peoples as such, whose Indigeneity has been ‘in the way’ of development from the 1850s onward. Private property requires before all else the deterritorialization of those whose relations with the land do not revolve around its commodification. Violence against Indigenous nations, and especially Indigenous women, is not incidental to capitalist development but is a prerequisite to capitalist subsumption in the settler-colonial context. In requiring the death of either Indigeneity or the person, capital constitutes Indigenous struggle as an antagonist, interrupting both the subsumption of labor and the circulation of capital (even as such struggles may also self-constitute themselves in a variety of ways).     

Policing Mental Disorder: Controversies, Myths and Realities

In this article the premises on which Section 136 of the Mental Health Act 1983 have been evaluated traditionally will be outlined and assessed using data from a recent empirical study. In examining the nature of police action in implementing this provision it is shown that police discretion and ability to act autonomously is constrained by the social context within which officers become involved in incidents and the external influences impinging on police decision making. It is suggested that legalism is inadequate both in accounting for the social realities of policing and relevant social policy implications. Instead, a social constructivist approach capable of accounting for wider influences on police action and mental health policy more generally is advocated as the basis on which to evaluate the future use of the provision.

Mixture structure analysis using the Akaike Information Criterion and the bootstrap

Given i.i.d. observations x1,x2,x3,...,xn drawn from a mixture of normal terms, one is often interested in determining the number of terms in the mixture and their defining parameters. Although the problem of determining the number of terms is intractable under the most general assumptions, there is hope of elucidating the mixture structure given appropriate caveats on the underlying mixture. This paper examines a new approach to this problem based on the use of Akaike Information Criterion (AIC) based pruning of data driven mixture models which are obtained from resampled data sets. Results of the application of this procedure to artificially generated data sets and a real world data set are provided.     

Sexual minority youth in romantic relationships: Associations with youth well-being

This study investigated differences in depressive symptoms, loneliness, and self-esteem for monosexual (lesbian, gay) and plurisexual (bisexual, pansexual, queer) sexual minority youth (SMY) by relationship status (single, partnered) and relationship configuration (same-gender partner, different-gender partner). Participants included 338 SMY (M_age = 19.10 years) who reported on their relationship status, partner's gender identity, well-being, and ability to confide in partner about LGBTQ issues. Results indicated that for plurisexual youth, single status was associated with greater loneliness; plurisexual youth with same-gender partners reported fewer depressive symptoms and marginally greater ability to confide in their partner about LGBTQ issues than those with different-gender partners. Findings reveal similarities across SMY while also highlighting some unique challenges among plurisexual youth with different-gender partners.
