融合文化本质与受众自我赋权

融合文化本质上是一种参与式和互动式文化。在传播新技术的驱动下,受众通过参与和互动以生产融合文化,并与＂传者生产＂进行博弈而实现了自我赋权,最终分享了原来由垄断媒介文本和媒介文化生产的＂传者＂所牢牢掌控的媒介文化权力。融合文化还是一种新型的大众文化,也是现阶段正在出现的新兴文化样式和文化特征。当前,融合文化中受众的自我赋权及其赋权模式不断扩张和深入发展,但却面临着复杂的现实困境。     

自然法阐释与主权的契约论建构——洛克与卢梭政治理论创建理路比较

在西方政治思想史上,自然法理论与社会契约论有着悠久的传统.文章试对洛克与卢梭这两位资产阶级思想家有关自然状态、自然法和自然权利的理论进行简单梳理,对各自自然法理论体系的社会契约论归宿进行相应解说,分析他们理论建构与阐释上的一致与歧义.源于对自然法理论之预设分殊,洛克从双契约走向了有限主权理论,而卢梭用社会契约阐发了人民主权理论.     

Clients' Attributions of the Presenting Problem and the Therapeutic Alliance in Couple Therapy: Systemic Versus Intrapersonal Perspectives

The therapeutic alliance is central to couples' therapy success. The current study examined associations between couples' initial agreement and causal attributions of the presenting problem and changes in the therapeutic alliance. To test study hypotheses, 85 couples were recruited from a university training clinic focused on couple and family therapy. Couples completed an intake questionnaire concerning their attribution of the presenting problem, either as systemic or individual, and therapeutic alliance was assessed at the end of sessions 2–8. A dyadic multilevel model revealed that a disagreement in the couple's attributions of the problem (with one viewing it as systemic, the other as individual) was associated with a larger initial discrepancy in the couple's therapeutic alliance, as well as a decline in the discrepancy over time. Findings were discussed in the context of systemic family theory, with implications for improving assessment, treatment, and psychoeducation aimed toward couples in distress.     

Optimal asset allocation for participating contracts with mortality risk under minimum guarantee

Abstract

We investigate an optimal investment problem of participating insurance contracts with mortality risk under minimum guarantee. The insurer aims to maximize the expected utility of the terminal payoff. Due to its piecewise payoff structure, this optimization problem is a non-concave utility maximization problem. We adopt a concavification technique and a Lagrange dual method to solve the problem and derive the representations of the optimal wealth process and trading strategies. We also carry out some numerical analysis to show how the portfolio insurance constraint impacts the optimal terminal wealth.     

Coordinate sampler: a non-reversible Gibbs-like MCMC sampler

We derive a novel non-reversible, continuous-time Markov chain Monte Carlo sampler, called Coordinate Sampler, based on a piecewise deterministic Markov process, which is a variant of the Zigzag sampler of Bierkens et al. (Ann Stat 47(3):1288–1320, 2019). In addition to providing a theoretical validation for this new simulation algorithm, we show that the Markov chain it induces exhibits geometrical ergodicity convergence, for distributions whose tails decay at least as fast as an exponential distribution and at most as fast as a Gaussian distribution. Several numerical examples highlight that our coordinate sampler is more efficient than the Zigzag sampler, in terms of effective sample size.     

企业非市场与市场行为及其竞争特点对企业绩效的影响研究

随着我国企业步入激烈的动态竞争时代,企业的成功不仅依赖于产品和服务、分销渠道、供应链、价格等市场行为,也依赖于企业与政府、社会公众以及各种利益相关者之间的关系等非市场行为.本文首先提出了一个企业非市场、市场行为(或回应)及其竞争特点与企业绩效关系的理论模型及其相关假设,然后以2004年至2006年我国钢铁、汽车、医药、日化、电力和电信等六个行业中的30家企业的非市场与市场行为为样本,通过结构内容分析方法对有关企业竞争行为新闻报道的编码数据进行处理和信效度检验,接着在对各种非市场与市场行为频数统计和独立样本T检验的基础上,运用回归方程模型进一步分别检验了非市场与市场行为及其竞争特点对企业绩效的影响.最后,本文将研究结果与中国企业现实情况进行了相互对照,并提出了研究结论和相关启示.     

顾客导向和创新导向对企业绩效的影响机制研究

在市场导向相关研究的基础上.本文探索了顾客导向(Customer Orientation)以及创新导向(Innovation Orientation)经由组织学习(Organizational Learning)对公司绩效(Firm Performance)的影响.通过对欧洲的390家制造企业的调查.发现顾客导向和创新导向都对组织学习产生正向影响,组织学习提高了公司的新产品绩效(New Product Performance).最终提升了公司绩效.最后,文章讨论了本研究的理论和实践意义,以及未来的研究方向.     

战略导向的概念、先行因素及其绩效影响机制研究综述

在对现有文献进行梳理和回顾的基础上,系统地剖析并界定了战略导向的内涵,探讨了战略导向的类型,并解释了战略导向的先行因素及其对组织绩效产生影响的机制.最后,对战略导向相关研究的未来方向进行了展望.     

国有股和法人股对公司业绩的影响--公用事业型上市公司的实证研究

公司的股份集中于少数几个大股东手中是中国公司股权结构的一个普遍特征,研究这些大股东如何凭借其持股地位影响公司业绩是中国公司股权结构研究的一个非常重要的问题.本文选取了在上交所上市的公用事业型公司1998年至2002年的平行数据进行实证研究,结果表明,法人股对公司业绩有积极影响,国有股对公司业绩的影响视具体情况而定.
