考试作弊现象的存在是对考试公平公正的严峻挑战,近年来考试作弊现象呈现上升势头,作弊手段更加现代化,作弊的主体多元化.这既有客观原因,又有主观因素.注重诚信教育,改革考试形式,强化考务管理,建立科学的评价体系,加快考试立法等多方面共同努力,才能形成良好健康的学风和考风. 相似文献

声乐与其它的艺术形式存在着明显的区别,由于难以形象地对声乐的乐理、思想等进行表达,因此在声乐教学的过程中如何有效地让学生更好地理解声乐知识,更好地掌握发声技巧等一直是广大声乐教师关注的重点。鉴于此,文章主要就声乐教学中的因材施教进行研究,通过努力在声乐教学中推动因材施教,学生才能对此会产生更浓厚的兴趣,更好地用声乐来表达内心的思想与情感。 相似文献

As documented in the literature, the effects of firm size, financial leverage, and R&D expenditures on firm earnings are inclusive. Our hypothesis is that the inconsistent empirical results of such effects may be driven by the regression models implemented in data analysis. Using the quantile regression (QR) approach developed by Koenker and Basset (1978), this study analyses S&P 500 firms from 1996 to 2005. We find that the effects of firm size, financial leverage and R&D expenditures on firm earnings differ considerably across earnings quantiles. Comparing the results from the QR approach with those from the ordinary least squares (OLS) and least absolute deviation (LAD) methods, this study further explains the puzzling relationship between firm size, financial leverage, R&D expenditures and firm earnings. 相似文献

基于结构方程模型的集聚农户共生认知及影响因素分析:以重庆市为例 总被引:2,自引:0,他引:2
研究目的:探讨对集聚农户共生、集聚区土地利用率提高的影响因素,为提升农户共生的认知水平、优化农户共生关系及促进资源的节约集约利用提供有效路径及理论指导。研究方法:参与式农户调查,结构方程模型。研究结果:(1)户主自身特征、农户家庭特征、集聚共生效益特征及外部环境与政策特征这4类外源潜变量对农户共生认知产生重要影响且影响程度大小不同,其中,集聚共生效益特征的影响最为显著,外部环境与政策特征、户主自身特征和农户家庭特征的影响依次减弱;(2)是否为干部、对原集聚模式的满意度、是否促进农户生产生活条件和政府对集聚区的补贴力度分别对这4类外源潜变量具有较好的解释能力。研究结论:显化农户共生效益、增强"精英"农户及村干部的正向引导、提升农户成员受教育水平、培养农户"共生共荣"理念等是深化农户共生关系,促进和谐乡村人居环境建设的重要路径。 相似文献

This article explores the relationships between three dimensions of contingent pay – performance‐related pay, profit‐related pay and employee share‐ownership – and positive employee attitudes (job satisfaction, employee commitment and trust in management). The article also examines a conflicting argument that contingent pay may intensify work, and this can detract from its positive impact on employee attitudes. Of the three contingent pay dimensions, only performance‐related pay had direct positive relationships with all three employee attitudes. Profit‐related pay and employee share‐ownership had a mix of negative and no significant direct relationships with employee attitudes, but profit‐related pay showed U‐shaped curvilinear relationships with all three employee attitudes. The results also indicated that performance‐related pay is associated with work intensification, and this offsets some of its positive impact on employee attitudes. 相似文献

Many people are relatively unsatisfied with the democratic system as it currently exists. In this empirical research note, the authors present evidence that German workers, who perceive their own pay or top managers’ pay as unfair, are on average significantly less happy with the democracy in Germany. Thus, fairness perceptions in the labour market and of income inequality seem to have spillover effects on the overall satisfaction with the democratic system. 相似文献

This paper assesses to what extent differences in the characteristics of individuals (micro‐level perspective) and country‐specific factors (macro‐level perspective) can explain country differences with respect to material deprivation levels. Thus, our work aims to simultaneously consider the macro dimension and the predominantly individually‐oriented study field of material deprivation using multilevel techniques. We make use of the European Union Statistics on Income and Living Conditions. Our results show that country‐specific factors seem to be much more relevant than individual effects in explaining country differences in material deprivation. We estimate that the introduction of country‐specific factors reduces the proportion of total variance due to between‐country differences in deprivation by 72.7 percent, while individual‐level variables reduce this proportion by only 9.4 percent. We also show, through interaction variables, that the effect of sociodemographic characteristics can be shaped by institutional and structural factors, especially by the level of GDP. 相似文献

Individuals, differing in productivity and life expectancy, vote over the size and type of a collective annuity. Its type is represented by the fraction of the contributive (Bismarckian) component (based on the worker's past earnings) as opposed to the non‐contributive (Beveridgean) part (based on average contribution). The equilibrium collective annuity is either a large mostly Bismarckian program, a smaller pure Beveridgean one (in accordance with empirical evidence), or nil. A larger correlation between longevity and productivity, or a larger average life expectancy, both make the equilibrium collective annuity program more Beveridgean, although at the expense of its size. 相似文献

The gender pay gap is an important issue today in the U.S. The lack of transparency surrounding pay in businesses is viewed as one cause of this gap. The first section of this article explores the origins of the gender pay gap and presents a brief history of pay transparency. Then, I propose a framework built from three continua that breaks the concept of pay transparency into types and levels. Using this framework, I offer guidance to organizations that want to increase pay transparency. The article concludes with a discussion of the risks associated with increased pay transparency and suggestions for future research. 相似文献

Employees of a certain rank are motivated by the pay gap between them and the levels above (upward comparison), and the pay gap between them and the levels below (downward comparison). In some cases, employees face multiple upward comparisons such as immediate and subsequent upward comparisons. We hypothesise that upward comparison matters more than downward comparison, and in the case of multiple upward comparisons, the immediate one matters more than the subsequent ones. We also hypothesise that the pay gap effect resulting from the upward/downward comparison ought to be non‐linear in that performance increases with pay gap size at a decreasing rate. The results from two empirical studies, namely, a longitudinal field study and a laboratory experiment, largely support our hypotheses. 相似文献
