Building the Knowledge Stock: Lags,Depreciation, and Uncertainty in R&D Investment and Link with Productivity Growth

The search for an appropriate methodology to investigate the relation between R&D investment, knowledge stock and productivity growth is the main purpose of the paper. In analogy with physical assets, we present a model of knowledge capital formation which allows the calculation of the relevant user cost, as well. The proposed model accumulates R&D investment based on a stochastic gestation lag and a geometric depreciation of the stock. The basic parameters underlying the lag structure differ according to the types of research expenditure. The approach is applied to public R&D investment in Italian agriculture; the results provide interesting information about the economic structure of public research effort in Italian agriculture and plausible estimates of its internal rate of return.     

行为决策理论及决策行为实证研究方法探讨

作者对行为决策理论发展的历程及各阶段中决策行为的实证研究方法进行了梳理,发现决策行为的实证研究方法在很大程度上决定了行为决策理论发展的进程。在对决策行为一般实证研究方法及其特点进行分析之后,作者认为观察法较适用于决策行为的初步探索性研究;调查法则较适用于一般决策行为的总体状况和特征的研究;如果理论假说源于决策者某些特定的、深层次的主观动机,假设的证实或者证伪又需要大量的检验,实验法的优势比较明显。为了取得对本研究的实证效果,这里对如何将实验法应用于中国投资者决策行为研究做了一次实证性尝试,以供学术争鸣。     

论公权伦理的性质、对象与意义

公权的特有属性决定其总会以异化的形式出现,应该从伦理层面寻找新的更深层次的救治途径。公权伦理建设有益于现代社会伦理道德普遍正当性的实现,公权伦理的研究对象和主要内容包括法的意义上的权利关系伦理、公权运行中的伦理、公权制度伦理、公权行使主体道德建设、执政党政治伦理道德建设和公权道德规范等。公权伦理研究和建构有利于在更高层面上探索公权运行规律和公权伦理建设规律,促进社会主义和谐社会政治文明和精神文明建设。     

五代书院考略

五代时期民间所办儒学读书处多为家族所有的私塾,个别私塾召收异姓学生共同念书,从而成为义塾,但其异姓生员有限.宋初四大书院的兴起,与宋代扩大科举考试有关.唐代文献中的"书院",不过是书房而已.     

高职院校产学研合作教育的探索

产学研结合是指由学校和企业、科研院所在功能与资源优势上的协同与集成化,是技术创新的对接与耦合,是科技成果转化和产业化的有效实现形式和途径。产学研合作是将理论学习与实践训练相结合,培养学生实践能力和创新精神,全面提高学生素质的一种新型的教育模式,是高职教育进一步发展的必然趋势。高职教育走产学研相结合的道路,成为高职教育改革的重中之重,对新型人才的培养具有十分重要的现实意义。

上海市工业"三废"的环境库兹涅茨曲线研究

采用1982-2005年上海市"三废"数据进行了数量经济模型分析,结果表明,上海市人均工业废气和人均工业固废呈现出倒U型曲线,但是人均废水呈现U型曲线.上海市人均工业废气和人均工业固废已经超过了库兹涅茨的转折点,但是人均工业废水还未超过环境库兹涅茨的转折点.     

上市公司自愿性披露信息影响因素研究——基于沪、深上市公司的实证检验

本文在文献综述和理论研究的基础上,运用多元回归建立模型,对上市公司自愿性披露信息影响因子进行了实证分析。结果发现,上市公司自愿性披露信息与盈利能力、发行股票类型、会计师事务所规模、公司规模和资产负债率等因素成显著正相关,而与股权集中度及行业类型没有显著相关关系,并对结论进行了相关分析。     

Comparing the impact of management support on police officers’ perceptions of discretionary power and engagement: Australia,USA and Malta

Abstract

This paper uses Social Exchange Theory as a lens for comparing the impact of management support upon police perceptions of discretionary power and employee engagement, across three countries. A survey-based, self-report process collected data from 193 police officers in Australia, 588 from the USA, and 249 from Malta. Structural equation modelling was used to analyse the data. The findings suggest a significantly different management support context across the three countries, as well as significantly different perceptions of discretionary power. Across the three countries, police perceived relatively poor satisfaction with organizational management support and only some engagement levels. However, USA police perceived significantly more discretionary power than the other country samples. These findings provide greater clarity about the link between management support, discretionary power and engagement for the police officers. Since employee engagement likely affects policing outcomes, the findings suggest that poor management support of police officers could negatively affect the provided service. Potential strategies to enhance police engagement include (a) training police managers about how to manage so as to promote greater engagement, and (b) modifying police managers’ performance indicators in line with achieving better police engagement.
