设备类实践教学教材系统性知识体系探讨

我国工科院校认识实习和生产实习的实践教学大都各自编写讲义,其内容都比较零散,没有形成系统性的知识体系。这与社会企业需求的重点知识内容和难点知识内容有较大的差距,导致了实践教学质量不能大幅提高。依据社会企业需求的基本点、重点和难点知识内容,构成认识实习和生产实习全过程的三个层次的系统性知识体系,必将大幅度提高专业教师实践教学水平、实践教学教材建设和实践教学质量。     

Broadband׳s contribution to economic growth in rural areas: Moving towards a causal relationship

This paper uses recent data on both broadband availability and adoption to empirically gauge the contribution of broadband to the economic growth of rural areas of the United States over the past decade. Availability data from the National Broadband Map aggregated to county level is used in conjunction with county-level adoption data from Federal Communication Commission. Economic variables of interest include median household income, number of firms with paid employees, total employed, percentage in poverty, and the percentage of employees classified as either creative class or non-farm proprietors. A propensity score matching technique (between a “treated” group associated with various broadband thresholds and a control group) is used to make preliminary causal statements regarding broadband and economic health. Growth rates between 2001 and 2010 for different economic measures are tested for statistical differences between the treated and non-treated groups, restricting the analysis to non-metropolitan counties. Results suggest that high levels of broadband adoption in rural areas positively (and potentially causally) impacted income growth between 2001 and 2010, and negatively influenced unemployment growth. Similarly, low levels of broadband adoption in rural areas lead to declines in the number of firms and total employment numbers in the county. Broadband availability measures (as opposed to adoption) demonstrate only limited impacts, suggesting that future broadband policies should be more demand-oriented.

基于多级库存的电网运维物资安全库存优化配置研究

针对电力公司运维物资多级库存体系与安全库存配置现状,结合安全库存聚集效应,文章提出了周转库安全库存差异聚集策略。在综合考虑库存持有成本与普通、紧急配送成本的基础上,构建了安全库存优化配置模型。通过两类电网运维物资实际数据的分析,验证了差异聚集策略下成本低于全部聚集以及全部分散策略,可以为电力公司物资集约化、差异化、精益化管理以及仓库定额配置提供依据。     

从经适房政策解析政府在社会保障均等化中的角色定位

文章从非受益群体对于经适政策公平性的质疑角度入手,挖掘出导致社会普遍不公平感的更深层次原因,着重体现公民的情感接受,并借助经济学理论,尝试重新定义社会保障公平性原则,以社会保障均等化概念代替社会公平概念来解释经适房政策,从而推进政府角色的进一步转变。     

Extending the scope of hotel client reactions to employee injustice: Hotel employer reviews on the Internet

Third-party literature is concerned about the way others perceive what happens in organizations. When dealing with the perceived justice of the employer-employee relationship, it has mainly adopted an on-site approach. The scarce research focusing on the consequences of perceived justice for client variables in hotels has shown that it can impact client loyalty. In this study, we adopt an on-line view, and we analyze how the comments posted by hotel employees on the Internet about their work conditions influence guest perceptions. This topic is relevant because it is well known that clients’ perceptions influence client satisfaction, WOM and revisit intentions. Through an experiment based on real hotel employer reviews, results confirm that these comments have an impact on the organizational image dimension of service quality, hotel clients’ satisfaction, WOM, and revisit intentions. Thus, as occurs with client eWOM, hotel managers should be aware of these comments and manage them appropriately.     

Unfairness in consumer services: Outcomes of differential treatment of new and existing clients

In a consumption context, there is a growing interest in understanding unfair behaviour of firms towards customers. Our research focuses on unfairness perceptions driven by differential treatment, particularly through price discrimination, i.e. the practice of charging differential prices to different customers. Our purpose is to investigate the consequences of these practices for unfairness perceptions, satisfaction, trust and patronage, showing a dual perspective: the perceptions of new vs existing clients when they face the advantaged or disadvantaged conditions. A survey-based experimental design approach was used. We conclude that unfairness perception is stronger for existing than for new clients, prompting negative attitudinal and behavioural consequences when the former are exposed to disadvantaged conditions in relation to the latter. Our study aims to provide marketers with a perspective on the pitfalls related to differential treatment between present and prospective clients, with implications in terms of design and implementation of customer management strategies.
