Recently, an online Q&A tool has become an essential part of individual communities and organizations of experts on specific topics. Using the answers to questions about specific topics will help such communities work more efficiently in their fields. Currently, Q&A online communities are adopting gamification to engage users by granting awards to successful users. In this paper, we investigate how to mine award achievement histories to find expertise. We propose the use of sequence analysis and clustering techniques. Specifically, we study the history of Stack Exchange, a large Q&A community that employs gamification. To the best of our knowledge, this is the first study of using award achievement history to find expertise in Q&A communities. 相似文献

Comparison between Japan and other advanced countries shows that the relative poverty rate is high in Japan, and that many of the poor households are those with a non‐regular worker. As for mobility between income classes, the proportion of households remaining in the poor class for a long period of time in Japan is close to the average for EU countries. The panel estimation of its effect on wages shows that the raising of the minimum wage is statistically significantly associated with an increase in wages of non‐regular workers, in particular, female, but does not seem to decrease employment. The result shows that for male non‐regular workers, firm‐provided training promotes their transition to regular employment, and that for female non‐regular workers, occupational training promotes their transition to regular employment at different firms. 相似文献

While scholars have long recognised the influence of firm decisions on aspects of compensation (e.g. pay level and pay mix), prior compensation studies offer an ambiguous understanding regarding their scope. Some studies argue that firms customise compensation decisions according to employee groups, whereas others assume that firm compensation decisions apply uniformly throughout a firm. To address this research gap, the current study analyses pay levels and pay mixes for R&D employees and administrative employees in US high‐technology firms. Our empirical analyses show that firms make distinct compensation decisions for these two job families, but these decisions are ultimately consistent. These findings highlight firms' intention to strike a balance between customising compensation systems according to employee groups and maintaining internal consistency. Our findings add interesting insights to the strategic HRM and talent management literatures, which claim that firms should differentiate among employees when designing HRM systems. 相似文献

This paper examines the welfare comparisons between a freely floating, a managed floating, and a pegged exchange rate regime.
We compare the expected loss under these regimes by modifying and generalizing Hamada’s (2002) model to accommodate intervention
policy. We consider the de jure and de facto classifications, where the former is defined by the officially stated intentions of the monetary authorities, while the latter
is based on the actually observed behavior of the nominal exchange rate. We first examine the exchange rate regimes from the
central bank’s policy stance and the actual exchange rate policy. Next we assume that the regime which the private sector
perceives according to an official announcement may be different from the one adopted actually by the central bank. We examine
nine combinations of the de jure and de facto regimes. We interpret that, whenever they are different, there is informational friction between the central bank and the
private sector. We show that the welfare level of a small country under freely floating is no less than that under other regimes,
and that with some restrictive conditions, the de facto pegged or de facto managed floating is close to freely floating. This partly explains “Fear of floating” and “Fear of pegging”. 相似文献

Recent empirical evidence reveals considerable divergence between management reports and employee reports regarding organizational high performance work practices (HPWPs). This divergence implies that employees may not participate in some HPWPs that are formally present in their organizations, but also, that employees may participate in HPWPs that are not formally present in their organizations. In this study, we examine the implication of the latter case (i.e., employee participation in “informal” HPWPs) for employee‐level and organization‐level outcomes. Our analyses, using data from the Statistics Canada Workplace and Employee Survey, suggest that employee participation in informal HPWPs is associated with enhanced job satisfaction and workplace profitability in a similar way as employee participation in formal HPWPs is associated with these outcomes. 相似文献

We consider the incomplete assets market and assume that the market has no-arbitrage. Then there are many equivalent martingale measures associated with the market. Among them, a probability measure which minimizes the relative entropy with respect to the original probability measure P, has a special importance. Such a measure is called the minimal entropy martingale measure (MEMM). In a previous paper, we have proved the existence theorem of the MEMM for the price processes given in the form of the diffusion type stochastic differential equation. In this article we discuss the MEMM of the jump type price processes, or especially of the log Lévy processes, and we give the explicit form of MEMM. 相似文献

Small firms have been considered to be an important element of the industrial structure in Japan since the turn of the century. In this paper the history of small business in Japan is examined. In particular, the dramatic development of the technological and managerial ability of small firms within the last two decades is analyzed. Under the regime of rapid industrial restructuring in Japan, small firms are identified as developing their own diversive management strategies, especially with respect to international trade and the implementation of information and high technology. 相似文献

Abstract. This paper describes innovation from the viewpoint of biologic evolution, a complex adaptive system. First, three characteristics of complex adaptive systems – variation, interaction and selection – are explained. Second, we propose that variation in R&D activities is brought about by innovation seeds, which can be subdivided into reproduction and mutation types. Third, taking into account the concept of an innovation seed, we propose our innovation creation process model. Finally, our proposed concept is validated through case studies of (i) a mass analyser business by Shimadzu and (ii) a carbon nanotube business by NEC. 相似文献

We examine three tools that can enhance coordination success in a repeated multiple-choice coordination game. Gradualism means that the game starts as an easy coordination problem and moves gradually to a more difficult one. The Endogenous Ascending mechanism implies that a gradual increase in the upper bound of coordination occurs only if coordination with the Pareto superior equilibrium in a stage game is attained. The Endogenous Descending mechanism requires that when the game’s participants fail to coordinate, the level of the next coordination game be adjusted such that the game becomes simpler. We show that gradualism may not always work, but in such instances, its effect can be reinforced by endogeneity. Our laboratory experiment provides evidence that a mechanism that combines three tools, herein termed the “Gradualism with Endogenous Ascending and Descending (GEAD)” mechanism, works well. We discuss how the GEAD mechanism can be applied to real-life situations that suffer from coordination failure. 相似文献
