中古道教仙传中的"食桃修仙"母题研究

中古道教仙传中,"食桃修仙"母题的产生有其相应的时代背景和文化背景。在探究该母题产生的基础上,从内外两方面分析了"桃"被仙化的多重原因。就外因而言,桃被仙化与神仙信仰的广泛流传有关。就内因而言,桃被仙化与桃特殊丰富的文化内涵紧密相连。进而以"食王母桃"这一母题为中心梳理"食桃修仙"母题的流变。该母题的流变与桃被赋予的神效和异形密切相关,由此导致"食桃修仙"母题呈现出神异浪漫的美学风格。     

控股股东自利行为选择与上市公司股权制衡关系研究——基于股权结构的内外生双重属性

本文通过检定公司股权结构的内外生双重属性以及探索公司股权制衡的影响作用,研究了我国上市公司控股股东自利行为的选择与股权制衡之间的关系。站在股权结构外生性的角度,股权制衡能够制约控股股东与其控制上市公司之间的关联交易以及侵占型关联交易行为,但无法制约上市公司的派现行为,主要是因为公司中小股东把关联交易而不把派现视为控股股东的自利行为;站在股权结构内生性的角度,股权制衡受到控股股东的自利行为的影响,表现为关联交易使得中小股东对控股股东的制衡作用增强,但上市公司派现行为降低了这一制衡作用,而且在考虑股权结构内生性的情况下,股权制衡度对控股股东自利行为的制约作用减弱甚至消失。     

连带责任治理在供应商集群中的有效性研究

在核心企业与供应商集群的渠道关系情境下探讨连带责任治理对机会主义行为的作用,将网络中心性和使用渠道权力纳入连带责任治理研究框架,考察二者对机会主义行为的影响以及对连带责任与机会主义行为之间关系的调节效应。以一家出口企业的供应商集群为研究对象,获得82个连带责任小组样本共246个被调查者的调查数据,应用SPSS 19．0软件和层级回归法对研究假设进行检验。研究结果表明,供应商之间的连带责任对其机会主义行为有显著的抑制作用;供应商领导者的网络中心性负向影响其他供应商成员的机会主义行为,并强化连带责任对机会主义行为的抑制作用;核心企业通过使用渠道权力负向影响供应商集群的机会主义行为,但会弱化连带责任对机会主义行为的抑制作用。     

员工积极组织行为影响因素的实证研究:工作-家庭冲突的中介作用

本研究对505名员工及他们的124名直接主管按照4∶1的比例做了配对调查并对调查结果进行多层数据分析,考察工作压力、工作匹配度、工作-家庭冲突对员工积极组织行为的影响,分析了工作-家庭冲突的中介作用以及员工外倾性人格特质的调节作用。结果发现,工作-家庭冲突对员工的积极组织行为产生显著的负向影响;工作-家庭冲突在工作匹配、工作压力与员工积极组织行为的关系中起到中介作用;员工外倾性人格特质对工作-家庭冲突与员工积极组织行为之间的关系有调节作用,即外倾性人格特质能够降低工作-家庭冲突的负面影响,减弱其对员工积极组织行为的不利影响。     

基于顾客策略性购买和退货行为的缺货保障策略价值研究

针对产品缺货, 本文基于顾客策略性行为在存在顾客无理由退货的条件下对两类缺货保障策略(即公开库存策略和缺货补偿策略)的价值进行了深入研究。本文分别建立了不提供任何缺货保障策略、公开库存保障策略和缺货补偿保障策略的理性预期均衡模型, 通过对模型进行最优化分析发现产品缺货对最优无理由退货价格没有影响;顾客策略购买行为会破坏公开库存策略对销量的积极作用, 但这种破坏作用可以通过提供慷慨的无理由退货服务来弥补, 并且公开真实库存策略的价值优于公开虚假库存;当缺货补偿效用高于补偿成本时(称为有效的缺货补偿), 缺货补偿策略的价值优于公开库存策略。最后, 本文用Matlab软件对上述模型进行算例分析, 验证了文中理论模型的正确性。     

我国上市公司银行贷款与投资行为的关系研究——基于终极控制人性质调节效应的分析

主要研究不同终极控制人上市公司的银行贷款数量和期限结构对其投资行为的影响,以揭示股东-债权人代理冲突和银行贷款作为治理机制在公司投资方面所带来的综合后果。研究结果表明,银行贷款与投资支出显著负相关,短期贷款比长期贷款对投资扩张的约束力更大;无论是国家终极控制还是非国家终极控制的上市公司中,短期贷款对投资扩张起到明显的制约作用,但是在国家终极控制的上市公司中,长期贷款对决策者产生了更大的过度投资激励;中央终极控制的上市公司中短期贷款发挥了约束作用,长期贷款作用并不明显;地方终极控制的上市公司中短期贷款的约束作用不显著,但是其长期贷款产生了明显的过度投资激励。     

Gender roles,HIV risk behaviors,and perceptions of using female condoms among college students

The purpose of this study was to examine relationships between gender roles and HIV risk behavior, and perceptions and acceptance of the female condom among college students (n = 410). It was hypothesized that high hyperfeminine females and high hypermasculine males – those adhering to traditional gender roles – would engage in more HIV risk behaviors, including alcohol and drug use and various sexual practices, than those with lower hyperfemininity and hypermasculinity. It was also hypothesized that higher hyperfeminine females as well as higher hypermasculine males would perceive the female condom more negatively and would be less likely to view the female condom as a viable form of protection in the future. It was also hypothesized that high hyperfeminine females and high hypermasculine males would not accept the female condom as an alternative form of protection. Implications for prevention interventions are discussed.     

三支决策模型及其研究现状分析

目的/意义二分类群体决策问题广泛存在于社会民生和区域经济中的各个领域,例如：公务员面试、酒店推荐以及交通出行路线选择等。因此,需要提出合理的二分类群体决策方法,从而为政府和相关企业提供决策支持。设计/方法在考虑个体后悔规避行为的基础上,建立二分类选择过程,获得个体和群体关于备选方案的二分类向量;进一步建立二分类共识过程,协助个体调整偏好,从而获得具有较高共识水平的二分类。结论/发现从最小调整成本视角,建立了后悔规避行为下二分类群体决策方法,更加贴近现实决策情景,进一步丰富了群体决策方法的应用范围。     

Symptoms of Eating Disorders Among Females in Drug Addiction Treatment

The aim of this study is to measure and describe symptoms of eating disorders among females in treatment for drug addiction in Norway. Previous clinical and epidemiological studies have revealed coprevalence between eating disorders and substance use or abuse. However, few studies have measured eating disorders in drug-using samples and even fewer within the context of drug treatment. In this study, 29 females with drug use disorder in residential treatment were tested with the Eating Disorder Inventory–2. A subgroup of 9 females (31%) with significant symptoms of eating disorders was identified. The characteristics of this group and possible clinical consequences are discussed.     

Trauma and health risk behaviors in people with severe mental illness

The current study tests the association between a composite measure of unsafe sex and sharing syringes for drug use with six of the more common lifetime traumatic/stressful events in 421 community mental health clients with severe mental illness (SMI) while controlling for psychiatric symptoms and related problems. A small but significant proportion of respondents said they had injected drugs with a shared needle in their lifetime (30, 7.2%), and a much larger proportion of respondents had engaged in unprotected sex (165, 39.2%). Unprotected sex and needle sharing were significantly correlated (Spearman’s rho = .20, p < .01). Frequency of lifetime traumatic events that occurred at least once was reported by one third to three quarters of clients depending on type of trauma. Regression analysis revealed that substance abuse and lifetime homelessness were significantly correlated with health risk behaviors. Practitioners need to be continuously vigilant to comorbid substance use and the housing needs of people with SMI. Limitations of the study include its cross-sectional design.
