笔者通过对正处于快速发展的某地质队的员工激励机制的调查,认为地勘单位由于激励形式单一,单位整体管理水平低,并未形成有效的、系统的激励机制,现有的激励措施偏重于外部激励而忽视内部激励和自我激励。激励投入不小但效果不佳。改进的措施应是:①建立健全贡献大小评价体系,深化奖酬分配制度改革;②建立动态用人、用工激励机制;③强化精神激励;④建立情感激励模式。 相似文献

按现行的预算编制要求,地质调查实验测试费用需拆分至相关财务费用科目并作为执行和审计的依据,但经估算,拆分数据与实际发生费用相去甚远。实验测试经费预算中存在的问题:(1)预算编制中无法“精细预算”、预算标准与实际情况不吻合;(2)实验测试工作周期不确定、受野外工作情况制约,实验测试类委托业务无法严格按照预算执行。对改进实验测试预算编制方法的建议:(1)实验测试预算管理跳出“费用科目”拆分,在预算中以工作手段体现,建议在预算附表中增加“实验测试费”表;(2)实验测试预算不区分是否为委托业务;(3)对实验测试工作手段标准进行动态调整;(4)给出实验测试工作适当的预算调整空间。 相似文献

This study used experimental and correlational techniques to examine perceptions that university faculty hold regarding the practice of professorial selling of examination textbooks to wholesalers. Faculty members (n = 236) from 14 universities and community colleges and a wide variety of academic disciplines responded to a web-based survey. We presented hypothetical selling situations to respondents with manipulated variables consisting of solicitation status (unsolicited versus solicited) and use of money (for faculty or for student activities). Both main effects and the interaction effect were significant such that respondents perceived it to be more ethical to sell an examination book when the book was unsolicited and when the money was being used to fund student activities. The variable most correlated with faculty members' beliefs that book selling is ethical and the faculty members' self-reports of whether or not they have engaged in bookselling was how widespread the practice appeared to be on campus. About 30 percent of faculty members sold textbooks over the past year at a dollar value of about $80 per professor. About 38 percent of respondents reported they believed the practice to be generally ethical. Implications for business ethics theory, students' moral development, and advancement of on-campus codes of ethics policies are discussed along with avenues for future research. 相似文献

Many firms conduct satisfaction surveys of their customers, with a view to using the analyzed results to identify areas of potential improvement. The weakness in this approach is that attributes with a lower satisfaction level might not be in need of improvement. They might merely be of little concern to customers. The present research develops several methods to identify areas that do require improvement. These methods include the importance–satisfaction (I–S) model, the improvement index, the quality-improvement index, the SERVQUAL survey, Kano's model, the extent of satisfaction, and the extent of dissatisfaction. An integrated model of service-quality measurement is used to cover all the customer surveys required for an international certification service company. In the case study, valuable information of various kinds is obtained from an analysis of the customer surveys. On the basis of this information, the firm can make appropriate decisions on areas for improvement, which are significantly different from those identified on the basis of a simple satisfaction survey. 相似文献

A comparison is given of (ordinal) measures of trust in government institutions that were collected with the aim of facilitating
comparisons between different modes and contexts of data collection. Statistical analyses reveal that the mode effect could
amount upto a 10% change of item nonresponse and a 9% change of the level of trust, whereas the context effect could lead
upto a 19% change of the bivariate associations of trust. The observed changes of both measures of central tendency and of
associations affect conclusions of social scientific research in isolated studies, which implies that comparative studies
are seriously hampered by bias related to mode and context, two sources of obscurity adding to the two other threats which
are differences of sample source and differences of question phrasing. 相似文献
