语音石化研究

石化现象是二语习得过程中的常见问题,其中语音石化首当其冲。造成语音石化现象的原因包括母语负迁移、情感因素、心理因素、教师因素等。避免语音石化现象应注意:(1)提醒学生注意英语与汉语的差异;(2)创设多层次的语音训练层次;(3)转变重语法轻语音的固有观念,提高学生的英语语音意识;(4)提高教学者的语音素质,等等。

Business visits,knowledge diffusion and productivity

We investigate whether labor mobility can be a distinct source of growth by studying the productivity impact of business visits (BVs), vis-à-vis that of other well-known drivers of productivity enhancement. Our analysis uses an unbalanced panel—covering on average 16 sectors per year in ten countries during the period 1998–2011—which combines unique and novel data on BVs sourced from the US National Business Travel Association with Organization for Economic Cooperation and Development (OECD) data on R&D and capital formation. We find that mobility through BVs is an effective mechanism to improve productivity, being about half that obtained by investing in R&D. This relevant finding invites viewing short-term mobility as a strategic mechanism and prospective policy tool to overcome productivity slowdowns and foster economic growth.     

Effects of child support and welfare policies on nonmarital teenage childbearing and motherhood

This paper is an assessment of the impact of child support enforcement and welfare policies on nonmarital teenage childbearing and motherhood. We derive four hypotheses about the effects of policies on nonmarital teenage childbearing and motherhood. We propose that teenage motherhood and school enrollment are joint decisions for teenage girls. Based on individual trajectories during ages 12–19, our analysis uses an event history model for nonmarital teenage childbearing and a dynamic model of motherhood that is jointly determined with school enrollment. We find some evidence that child support policies indirectly reduce teen motherhood by increasing the probability of school enrollment, which, in turn, reduces the probability of teen motherhood. This finding suggests that welfare offices may wish to place greater weight on outreach programs that inform more teenagers of the existence of strong child support enforcement measures. Such programs might reduce nonmarital teen motherhood further and thus reduce the need for welfare support and child support enforcement in the long run.

吴门画派的艺术成就初论

唐代以来中国绘画的发展,以明代董其昌等人所言,主要有"文人画"与"非文人画"两大传统,即"利"家与"行"家.各家均按各自的传统不断演进.明代中期吴门画派的绘画创作兼容"南、北"二宗,雅俗兼俱,"利""行"相渗,形成了"画格不纯"之局面.可以说在绘画史上是一次巨大的变革,呈现出"兼总条贯,揽其精微"的局面,并影响到后世的绘画创作.     

移动即时通讯服务持续使用意向影响因素研究

以TPB理论和消费者的3种角色视角为基础,对正在使用移动即时通讯服务的消费者进行调查,运用问卷调查法收集 401 份问卷数据,对数据进行分析.研究结果表明,态度和感知行为控制均显著正向影响持续使用意向,感知有用性、技术复杂度、网络外部性显著正向影响态度.主观规范对持续使用意向影响不显著,互惠对感知行为控制影响显著,这表明消费者对移动即时通讯服务的持续使用意向不仅受技术方面因素的影响,还受消费者之间人际关系因素的影响.     

基于主成分分析的上市公司利润操纵识别模型

从分析上市公司利润操纵的动机、主要手段及其影响的相关会计科目入手,设计26组有一定配比关系的财务指标,选取1995年～2004年中国证监会以利润操纵名义查处的全部上市公司为样本组,选取同行业规模相近且经营规范的公司为对比组,进行横向对比与相关分析;基于主成分分析法构建上市公司利润操纵行为的识别模型,确定利润操纵行为的识别边界,运用该模型对部分上市公司赢利真实性进行检验,为投资者识别上市公司的利润操纵行为提供一套科学可行的方法.     

技术创新网络的知识权力、结构权力对网络惯例影响

网络惯例是维系和协调技术创新网络顺畅运转的核心要素,权力和关系承诺作为技术创新网络中的关键因素,也影响着网络惯例的形成和发展。构建技术创新网络环境下知识权力、结构权力对网络惯例影响的结构方程模型,结合中国13个省、市高新技术企业的样本数据,利用SPSS和AMOS进行实证分析,检验组织成员间关系承诺的中介效应。研究结果表明,知识权力积极显著影响规范性承诺和工具性承诺,结构权力积极显著影响工具性承诺而对规范性承诺没有影响;知识权力和结构权力积极显著影响网络惯例;规范性承诺和工具性承诺积极显著影响网络惯例;规范性承诺在知识权力与网络惯例关系中具有中介效应,但是在结构权力与网络惯例关系中不具有中介效应,而工具性承诺在知识权力和结构权力对网络惯例的关系中均具有中介效应。深入探索网络惯例的内在规律,对指导技术创新网络情境下组织成员间的网络关系治理具有实践意义。     

The how and why of a firm’s approach to CSR and sustainability: a case study of a large European company

This paper aims to analyse “how” and “why” a company engages in CSR and sustainability. The “how” concerns the features of the firm’s CSR and sustainability approach, defined in terms of a firm’s strategy (implemented issues, initiatives and activities) and organization (organizational structures and roles and managerial systems adopted). The “why” refers to the key determinants, both internal and external, of CSR and sustainability. Finally, how the firm’s CSR and sustainability approach evolves over time and the relation between CSR determinants in various stages of the CSR evolutionary path are also investigated. The research method is based on the longitudinal analysis of a case study concerning a large multinational company operating in the telecommunications industry in Europe. The analysis of the case study shows that sub-cultural differences in the approach to CSR and sustainability may occur across hierarchical levels and functional units. Moreover, embedding CSR and sustainability principles doesn’t follow a linear and continuous process, made by sequential stages. Indeed, it can be characterized by an up and down evolutionary path, based on different stages with a changing emphasis given to CSR and sustainability issues. Finally, we find that the firm CSR and sustainability approach is not an autonomous choice, but it is a consequence of the contingent role played by both the external and the internal drivers and by their relative importance during the company’s CSR history.
