农村金融排斥理论视角下的“查干花”模式——对农村支付环境建设中自发机制问题的探讨

金融排斥是制约我国农村金融服务质量和水平的重要因素，研究解决作为基础性的金融服务的支付结算领域的金融排斥问题的路径，对于全面破解农村地区金融服务具有重要意义。本文以吉林省松原地区查干花养殖场内的兽医站通过转账电话为养殖场员工及附近农户提供非现金支付服务的发展为例，通过对当下农村自发衍生的支付服务机制进行了探讨，对破解农村支付领域金融排斥、推进农村金融产品和服务方式创新机制路径改进提出了建议。

MC1648两种改进型VCO的压控特性和频率稳定性研究

本文对2种改进型VCO的压控特性和频率稳定性进行了分析，并给出实际测量结果。结果表明,两VCO在变容管允许承受的整个反偏压范围内，压控特性具有较好的线性，频稳度达10^-4-10^-5级，大大优于一般频率固定的LC振荡器，所以适合于性能要求较高的场合使用。     

The demise of swidden-fallow agriculture in an Atlantic Rainforest region: Implications for farmers’ livelihood and conservation

The Brazilian Atlantic Forest is widely recognized for its high levels of biodiversity and endemism. Its vast region concentrates also a large number of small farmers, who historically have been practicing swidden-fallow cultivation. Globally, there is contradictory evidence of the current fate of this traditional, integrated agricultural system, and the new land uses may have a strong impact on farmers’ livelihoods and ecosystem conservation. In this study, we assessed the land cover and land use change in a watershed where slash-and-burn cultivation was prevalent, aiming at understanding the drivers of change and discussing past and possible future impacts, including the perception of farmers on the drivers of land use change. We combined information gathered from interviews with 15 key informant farmers and from the analysis of remote sensing images for the years 1957, 1978 and 2011. Swidden-fallow cultivation has declined steadily since the 1950s. Part of the land was abandoned and forest succession was allowed to occur, increasing the total forest area; an apparently positive outcome. However, conversion to pastures and Eucalyptus plantations not only used much of the open land but also converted successional forests through deforestation, based on remote sensing. The willingness of farmers to grow more Eucalyptus and raise more cattle further increases concerns about the prospect for conservation. Our approach, combining remote sensing-based land change quantification and interviews, revealed to be complementary, allowing a better understanding of the past and possible future scenarios for the land use dynamics.     

中国区域经济差异的国际比较：基于改进的区位基尼系数

改革开放以来,中国的经济增长速度很快,但与之相伴的一个问题是区域经济增长不平衡。本文对区位基尼系数的算法进行了改进,并利用改进过的算法测算了包括中国在内的世界10国2005年和中国1978—2007年的区位基尼系数。通过与其它国家的对比和本国30年的变动趋势,作者认为中国区域经济发展不平衡的主要原因是地区经济政策的差异和地区产业结构的差距。虽然中国要达到发达国家0．1左右的区位基尼系数是非常困难的,但从长远的角度看,0．2左右的区位基尼系数是应当努力的目标。

基于IFAHP和EVA的现代企业绩效管理模型研究

基于模糊数学理论的创新型企业绩效管理系统是经济领域正在探索的重要课题.随着经济环境的不断发展变化,知识资本、信息资本、企业创新氛围等无形资产和以人力资源为载体的智力资本正发展成为企业创造价值的重要源泉;同时,现代企业管理中除了要关注企业内部管理水平的提高外,更应注重客户满意度、企业产品市场占有率等外部因素.以企业绩效管理理论知识为基础,将改进的模糊层次分析法引入企业绩效管理系统,构建基于IFAHP和EVA的合理、有效、稳定的企业绩效管理模型,为企业绩效管理提供一条全新的途径.     

Building the bottom line by developing the frontline: Career development for service employees

Service firms must remember that the way they treat their employees is exactly how those employees will, in turn, treat customers. As such, taking good care of frontline personnel should be a top management concern. One way that service employees can be shown they are valued members of the organization entails the implementation of thoughtful and organized career development programs, initiatives which help increase employees’ job satisfaction and feelings of empowerment in their customer-facing roles. Before they can become enthusiastic about meeting the needs of their customers, employees have to feel that their own needs are being met within the organization. In this regard, firm investment in frontline employee career development programs will be money well spent: they are capable of reducing employee turnover and increasing customer satisfaction, loyalty, and profitability. This article provides a conceptual model of career development which should prove useful to service managers in evaluating their own career development efforts. Also presented herein is a framework for tying together many disparate areas of career development that have heretofore been handled separately in the services literature.     

The effect of household wealth on the adoption of improved maize varieties in Zambia

Production and price risks that could render input use unprofitable sometimes prevent rural households from benefiting from input technological change. The household’s ability to cope with such risks and hence benefit from input technological change is often positively related to its wealth or stock of productive assets. Empirical evidence, however, suggests a non-linear relationship between wealth and adoption of new agricultural technologies so that within a rural community, households on the lower wealth continuum behave differently from those on the higher level. Using farm level data collected from 300 randomly selected households in three districts of Zambia in 2004/2005 crop season, this paper first stratifies households into poorly- and well-endowed households based on their access to productive assets and estimates separate double-hurdle models for the adoption of improved, high yielding maize (IHYM) varieties for each group. The results show that factors influencing the adoption and use intensity of IHYM varieties differ between the two groups. This draws attention to the need for recommending wealth group-specific interventions to increase the adoption and use intensity of such varieties and their subsequent impacts on food security and general livelihoods of the households. The explicit testing for the possibility that differences in household wealth affect the way in which other variables influence adoption decisions is the paper’s unique contribution to the adoption literature.
