Gamification of Labor and the Charge of Exploitation

Recently, business organizations have increasingly turned to a novel form of non-monetary incentives—that is, “gamification,” which refers to a motivation technique using video game elements, such as digital points, badges, and friendly competition in non-game contexts like workplaces. The introduction of gamification to the context of human resource management has immediately become embroiled in serious moral debates. Most notable is the accusation that using gamification as a motivation tool, employers exploit workers. This article offers an in-depth analysis of the moral charge of exploitation. This article maintains that there are no clear grounds for believing that gamification of labor is exploitative and that if gamification of labor involves a wrong or vice, it must be something other than exploitation.     

Who benefits from partial tax coordination?

In this paper, we investigate whether partial tax coordination is beneficial to countries within and outside a tax union, in which countries are supposed to compete in taxes and infrastructure. Our results demonstrate that a subgroup of countries agreeing on a common tax rate can harm both member and nonmember states. This is in contrast to the classical findings that partial tax harmonisation is Pareto improving. When a minimum tax rate is imposed within a tax union, we demonstrate that it does not necessarily improve the welfare of the member countries. Moreover, both the high‐tax and low‐tax countries can be worse off. This conclusion is at odds with the classical result that a high‐tax country benefits from the imposition of a lower tax bound.

Interpersonal Relationship,Service Quality,Seller Expertise: How Important Are They to Adolescent Consumers?

Drawing upon social capital theory and psychosocial development theory, this paper argues that a true buyer–seller relationship is a key determinant of favorable consumer behaviors for adolescent consumers of hairstylist services. Other important determinants include quality of the service delivery process (i.e., service quality as measured by the five SERVQUAL factors) and quality of the core service (in this case, the hairstylist's expertise). A survey of 350 adolescent consumers confirms these predictions. It shows that a true interpersonal relationship negatively moderates the positive effects of service quality on consumer satisfaction with, and overall assessment of the hairstylist. This negative moderating effect is labeled resource substitution benefit and the argument made that this is the fourth social capital benefit. The theoretical and practical implications of these findings are discussed. © 2012 Wiley Periodicals, Inc.     

酶联免疫法与液相色谱-串联质谱法测定水产中氯霉素残留

运用酶联免疫法和液相色谱-串联质谱法测定水产中的氯霉素残留。结果显示,ELISA法最低检测限为0.0125μg/kg,鱼、虾、贝类样本的添加回收率为80.4%-101.3%,变异系数为5.7%-11.5%;LC-MS/MS法最低检测限为0.1μg/kg,样本添加回收率为82.7%-98.2%,变异系数为6.2%-9.7%。用酶联免疫法对实际样品进行检测,筛选出5个阳性样本,经液相色谱-串联质谱法确证亦为阳性,且测定结果一致。研究表明,酶联免疫法快速、灵敏、可靠,为水产品中氯霉素的残留检测提供了快速筛选方法,而液相色谱-串联质谱法准确度高,适用于阳性样本的确证和精确定量。     

实施国际劳工标准的贸易制裁模式比较研究

国际贸易与劳工标准挂钩已出现多种实现模式并存的局面。本文着重对现有的实施国际劳工标准的贸易制裁模式进行分析比较,梳理这些模式的适用条件和范围,预测这些模式的发展趋势。本文认为,贸易制裁模式强化了国际劳工标准在国际间的实施力度,但还有不少问题值得相关国家和组织继续探讨。纳入WTO制度的国际劳工标准实施模式将更具权威性、约束性和公正性。

行列式的计算方法与技巧

在高等代数中,行列式的求解是非常重要的,直接计算行列式往往是困难和繁琐的,特别当行列式的元素是字母时更加明显,因此熟练地掌握行列式的计算方法是非常重要的.行列式的重点是计算,应当在理解阶行列式的概念,掌握行列式性质的基础上,熟练正确地计算三阶,四阶行列式,也会计算简单的阶行列式的值.计算行列式的基本方法是:按行(列)展开公式,通过降阶来实现.但在展开之前往往先通过对行列式的恒等变形,以期新的行列式中能构造出较多的零或有公因式,从而可简化计算.     

一种新的混沌扩频序列产生方法

本文提出了一种新的混沌扩频序列产生方法。该方法基于神经网络的强大学习能力和副近非线性函数能力,应用具有全局最优的ＢＰ改进算法通过训练学习建立起具有混沌性态的优化神经网络模型,利用网络权值调整的灵活性来产生混沌扩频序列。计算机仿真结果表明,该模型产生的混沌扩频序列调整更容易,比基于单一混沌映射能产生更多符合扩频通信要求的扩频序列。     

Do Traditional Chinese Cultural Values Nourish a Market for Pirated CDs?

On one hand, Chinese consumers are well known for conspicuous consumption and the adoption of luxury products and named brands. On the other hand, they also have a bad reputation for buying counterfeit products. Their simultaneous preferences for two contrasting types of product present a paradox that has not been addressed in the literature. This study attempts to present an explanation of this paradox by examining the effects of traditional Chinese cultural values and consumer values on consumers’ deontological judgment of pirated CDs and the amount of social benefits they perceive they gain from them. We interviewed 300 Hong Kong Chinese consumers, and found that face consciousness increased materialism and risk aversion, thereby producing a favorable deontological judgment of pirated CDs. Face consciousness also has a direct effect on the amount of social benefits perceived in pirated CDs. Both favorable deontological judgment and perceived social benefits contributed to a strong intention to buy pirated CDs. The results are discussed in a cultural perspective.
