Exploring job crafting: Diagnosing and responding to the ways employees adjust their jobs

Recent research has developed an in-depth understanding of how workers change their jobs on their own to improve their performance and well-being, a process called job crafting. This research suggests that managers, coworkers, and organizations need a better understanding of how to manage job crafting to capitalize on its benefits and reduce costs. This article will help organizations diagnose the occurrence of job crafting, recognize the differences between goal-oriented approaches to job crafting as opposed to withdrawal-oriented avoidance job crafting, and identify the seven specific types of job crafting: work role expansion, social expansion, work role reduction, work organization, adoption, metacognition, and withdrawal. We conclude with recommendations for managers, coworkers, and organizations on how to diagnose and manage job crafting.     

Weekday seasonality of stock returns: The contrary case of China

We document that Chinese stock returns exhibit early-in-the-week effects opposite-signed to those observed worldwide. The period of analysis is 2001–2016. Dominated by individual investors, Chinese stock markets offer unique out-of-sample insight regarding the source of weekday seasonality, ascribed elsewhere to institutional investors’ trading patterns. High returns to the market and to small, speculative stocks early-in-the-week pose a refuter to the mood explanation for the conventional (negative) Monday effect. A battery of tests suggests that the patterns in the Market, SMB, and RMW factors are jointly associated with Chinese individual investors whose demand is tilted towards small, speculative stocks. Our findings point to a potential role of dominant investor type in driving weekday patterns and the RMW premium.     

The influence of the regional context on firms’ innovation patterns: evidence from Ecuador*

ABSTRACT

Using data from the Ecuadorean Innovation Survey of 2015, this paper identifies the innovation patterns that can be found in Ecuador. In addition, we analyse the influence of the regional innovation systems in determining these patterns. The results show that there are six differentiated patterns of innovation, although they all are related to the adoption and imitation of technologies. Finally, we observe that different regional characteristics condition the way in which firms organise innovation.     

湖南省研发投入的空间格局与创新协调发展对策

以湖南省14个市州为研究对象,运用首位度分析、ESDA探索性空间数据分析方法,研究湖南省各市州的研发投入(R&D经费、R&D人员投入)空间差异变化趋势和空间分异特征。结果表明:①湖南省内各市州R&D经费投入差距在逐渐缩小,但R&D人员投入差距在逐渐增大;②湖南省的R&D经费及R&D人员投入在各个市州之间存在明显的空间依赖及空间集聚现象,并在西部、南部周边市州呈现出大面积的低水平连片聚集特征;③湖南省R&D投入的空间演变特征并不显著,长株潭作为省会中心城市圈缺乏辐射带动力。研究最后提出了湖南省科技创新协同发展的对策建议。     

The effect of specific discount pattern in terms of price promotions on perceived price attractiveness and purchase intention: An experimental research

This study aims to investigate consumer perceptions and reactions in terms of specific discount patterns (fixed price, 40% discount, discount from 500 TL to 300 TL and 20% + 25% discount) in price promotion. According to the results, specific discount patterns in price promotion have a significant effect on perceived price attractiveness and purchase intention. When the specific discount patterns in price promotion and gender interaction were analyzed in terms of perceived price attractiveness, the scenario of the “discount from TL 500 to TL 300” significantly differentiated from both the control scenario (fixed price) and experimental scenarios for female. For males, no significant difference was found between the control and experimental scenarios. In terms of purchase intention, a significant difference was found between the fixed price scenario and the discount scenario from 500 TL to 300 TL and between the fixed price and 20% + 25% discount scenario. The theoretical managerial implications of the study were discussed, and future research suggestions were presented.     

Publishing characteristics,geographic dispersion and research traditions of recent international accounting education research

This paper describes, analyses and critiques accounting education research over the period 2005–2009. In doing so, it compares and contrasts the distinctive North American research tradition with that of Europe and the rest of the world. Six journals and 446 publications by 963 authors were included in the sample frame, along with a further 70 publications in other journals. The findings identify distinguishing characteristics among these publications that range from the composition of their editorial teams to the nature and type of output they publish. Evidence was found of geographic dominance and divergent research traditions which has mitigated against the development of a genuinely international accounting education research community. Possibilities for further research are identified and guidance for researchers publishing in this field is presented.     

Distributional effects of environmental taxes on transportation: evidence from Engel curves in the United States

Indirect taxes on transportation activities that pollute can correct externalities and close the gaps between private and social costs. However, policy makers often find such Pigou taxes difficult to implement because of political resistance due to possibly adverse affects on equity. For this reason it is important to assess the distributional aspects of environmental levies. This article estimates properties of the demand for transportation in parametric and non-parametric analyses of Consumer Expenditure Surveys for the United States and finds patterns in the resulting set of Engel curves. Private transportation using air flights and new cars has Engel elasticity above unity while public transportation via mass transit has Engel elasticity below unity. The findings can be interpreted in an important way since they show that a differentiated scheme of environmental taxes on transportation may function progressively. A Pigou scheme with larger taxes on modes of transportation that pollute more appears to coincide with larger levies on luxury modes preferred by richer households.     

我国非处方药（OTC）流通渠道模式研究

目前,我国OTC药品年销售额已超过400亿元人民币,年平均增长速度超过20%,成为世界上增长最快的市场。与此同时,各种体制的医药商业公司蓬勃发展起来;许多制药企业成立了自己的销售公司;外资药店攻城掠地;其他行业巨头大举入侵,使得OTC市场的流通渠道经历着前所未有的巨变。本文在分析OTC流通渠道模式的基础上,针对OTC厂商提出一些渠道建议。     

论中国风险投资退出机制的建立与完善

风险投资在经济发展中起着十分重要的作用 ,特别表现在 2 0世纪 90年代的美国经济中。然而 ,风险投资在中国的运作并不理想 ,主要是由于退出机制方面的问题。事实上 ,退出机制是关系到风险投资运作的关键因素。为了更好地促进中国高新技术企业和成长潜力大的中小企业的发展 ,中国应建立起畅通的退出机制 ,以带动中国经济的新一轮增长。     

基于MBP算法和深度学习的人脸识别

为了解决在深度学习提取人脸图像特征时,易忽略其局部结构特征和缺乏对其旋转不变性学习的问题,提出了一种基于单演局部二值模式(MBP)与深度学习相结合的高效率人脸识别方法。首先,用多尺度单演滤波器对图像进行滤波,得到幅值和方向信息;其次,用LBP算法和象限比特的方法进行编码,分块计算组合其直方图特征;然后,将提取的单演特征作为深度信念网络(DBN)的输入,逐层训练优化网络参数,得到优异的网络模型;最后,将训练好的DBN网络在ORL人脸数据库上进行人脸识别实验,进行识别率计算,其识别率为98.75%。所提出的方法使用无监督的贪婪算法,隐藏层设定为2层,使用反向传播算法优化网络。相较于已知的人脸识别方法,MBP+DBN算法对光照、表情和部分遮挡变化具有较好的鲁棒性,在人脸识别中识别率较高,具有一定的优势,为图像特征提供了一种新的识别方法。
