利用陕西省安康、商洛和宝鸡3市38家烤烟专业合作社的调查数据,基于不同法人治理结构视角,运用层次分析法构建绩效评价指标体系对两种不同类型的烤烟专业合作社进行实证分析。研究结果表明:38家烤烟专业合作社可以根据法人治理结构的不同分为“外部委托代理人型”与“内部委托代理人型”两种类型。“外部委托代理人型”烤烟专业合作社在社员人数、理事会核心成员构成比例、股权集中程度及监督力度等法人治理结构方面具有明显的优势,在吸纳了更多的农户入社、提高烤烟专业合作社经济收益的同时,也保证了绝大多数农户在股权分配、民主决策参与及合作社监督等方面的权利。这有利于基层民主的完善,有利于显著提高烤烟专业合作社管理效率,从而提高农户整体烟叶生产水平。因此,改善法人治理结构是促进农民专业合作社发展的重要途径。 相似文献

Stereotypes is one of the most researched topics in social psychology. Within this context, negative self‐stereotypes pose a particular challenge for theories. In the current work, we propose a model that suggests that negative self‐stereotypes can theoretically be accounted for by the need to communicate in a social system made up by groups with unequal power. Because our theory is dynamic, probabilistic, and interactionist, we use a computational simulation technique to show that the proposed model is able to reproduce the phenomenon of interest, to provide novel accounts of related phenomena, and to suggest novel empirical predictions. We describe our computational model, our variables' dynamic behavior and interactions, and link our analyses to the literature on stereotypes and self‐stereotypes, the stability of stereotypes (in particular, gender and racial stereotypes), the effects of power asymmetries, and the effects of intergroup contact. 相似文献

Framed within contextual systems model, this study examines how home and school operate together to shape behavioral and academic outcomes for 544 low-income African American (56%) and Latino/a (44%) elementary school-aged children (mean age?=?7.88 years, SD?=?1.46, 50% male). Using data from Welfare, Children, & Families Study: A Three City Study and multiple group path analysis, we found that for children in kindergarten through third grade, the adequacy of the home resources was positively related to applied problem scores (e.g. math literacy) and negatively associated with externalizing behavior. For fourth- to sixth-graders, the adequacy of classroom resources was negatively associated with applied problem scores. For both age groups positive teacher–child relational quality was also a positive predictor of externalizing behavior. Results revealed that barriers to parental involvement in school were a negative predictor of applied problem scores for low-income children in early and later elementary school. Implications for policy and practice aimed at strengthening opportunities for children and families from marginalized communities are discussed. 相似文献

现代设计之后的设计思想与实践不仅从环保的、生态的角度积极探讨研究通过设计建立新型的人与自然的和谐共生关系,而且尊重不同的文化,弘扬人文主义精神,并且取得了许多成就。但色彩设计作为现代设计中的重要因素,从设计理论研究和实践应用两方面都还存在不足。文章立足于色彩和色彩设计的本质属性,对色彩和色彩设计的概念、现象及应用进行反思和再认识,主张色彩设计应回归自然本质和人文精神的体现,并在色彩设计中建立系统观念,更好地对色彩设计进行定位。这样才能满足现代设计发展的需要,发挥色彩设计更大的作用。 相似文献

随着社会经济的发展,人们对现代产品已不再满足产品功能带来的物质享受,而是更多地追求产品的文化内涵和艺术价值。因此,现代产品设计应加强文化策略,赋予产品以文化品格,从而体现产品设计的独特文化风格和精神魅力,使现代产品设计在国际市场竞争中立于不败之地。 相似文献

Networks are well understood as crucial to the diffusion of HIV among injection drug users (IDUs), but quasi-anonymous risk nodes - such as shooting galleries - resist measurement and incorporation into empirical analyses of disease diffusion. Drawing on network data from 767 IDUs in Bushwick, Brooklyn, we illustrate the use of calibrated agent-based models (CABMs) to account for network structure, injection practices, and quasi-anonymous transmission in shooting galleries. Results confirm the importance of network structure and actor heterogeneity to the magnitude and speed of HIV transmission. Models further demonstrate that quasi-anonymous injections in shooting galleries increase the speed of HIV diffusion across the whole network and have the greatest impact on HIV seroconversion levels for IDUs at the network periphery. Shooting galleries are shown to be transmission hubs that operate independently of traceable structural ties, linking otherwise unconnected network components. CABMs potentially increase understandings of HIV diffusion dynamics by infusing computer simulations with empirical data. 相似文献

What motivates the geographic footprint of the supply chains that multinational firms (MNFs) deploy? Traditional research in the operations and supply chain management literature tends to recommend locations primarily based on differentials in production costs and the ramifications of physical distance ignoring the role of taxation. MNFs that strategically position parts of their supply chains in low‐tax locations can allocate the profits across the divisions to improve post‐tax profits. For the profit allocation to be defensible to tax authorities, the divisional operations must possess real decision authority and bear meaningful risks. Generally speaking, the greater the transfer of risk and control, the larger the allowable allocation of profit. These transfers may also create inefficiencies due to misalignment of business goals and attitudes toward risk. We model these trade‐offs in the context of placing in a low‐tax region a subsidiary that oversees product distribution (as a limited risk distributor commissionnaire, limited risk distributor, or fully fledged distributor). Our analysis demonstrates that the MNF's preferences regarding the operating structures are not necessarily an obvious ordering based on the amount of risk and decision authority transferred to the division in the low‐tax jurisdiction. We derive and analyze threshold values of the performance parameters that describe the main trade‐offs involved in selecting an operating structure. We find some of the optimal decisions to exhibit interesting non‐monotone behavior. For instance, profits can increase when the tax rate in the low‐tax jurisdiction increases. Numerical analysis shows that the Limited‐Risk Distributor structure is rarely optimal and quantifies when each alternative dominates it. 相似文献

民事诉讼代理制度作为现代民事诉讼制度中的一项重要制度,是法律面前人人平等原则的重要体现和保障。但是在我国农村劳动力向城镇转移、劳动纠纷增多的时代背景下,我国民事诉讼代理制度日益暴露出一系列的问题。课题组通过大量的实证调研,拟从民事诉讼代理制度的基础理论出发,结合我国目前农民工维权的实际,在理论上初步构建“来自于农民工,服务于农民工”的“草根律师”制度,解决有关农民工劳动纠纷案件中的诉讼代理难的相关问题。 相似文献
