我国公共部门人力资源绩效考核存在的问题及对策探析

近年来,我国公共部门采用绩效考核方式管理公职人员,取得了一定的成效,但也出现了一些问题,而这些问题阻碍了绩效考核方式在人力资源管理中的进展。为此,文章对目前我国公共部门人力资源绩效考核中出现的问题进行分析,探讨并提出公共部门人力资源绩效考核改革的思路与对策。     

电力企业部门主管绩效考评探讨

目前大多数电力企业对部门主管的考评存在制度不规范、指标设计不合理、考评方法原始、对考评结果疏于管理等问题。本文简述了电力企业部门主管绩效考评的意义,提出电力企业部门主管绩效考评设计应遵循的基本公开性、重视反馈性、可行性和实用性、重视时效性、定期化与制度化、立体化等原则。指出考评指标设计应注意选用的指标要简单、明确,指标设计要坚持定量指标与定性指标、个体指标与中层指标相结合的原则,要将任务绩效、管理绩效和关联绩效等指标相结合等问题。     

关于工业增加值率指标的探讨和分析

文章认为 ,地区工业增加值率的高低往往会受到两大因素的影响 ,一是部门结构 ,二是专业化分工。因而在采用该指标衡量宏观经济效益时 ,可能会与实际情况相悖 ,影响经济效益评价的科学性。因此 ,用工业增加值率作为经济效益评价指标 ,适用于专业化分工程度接近的同一行业、生产相同或相似产品的企业之间进行比较。     

关于我国水银行制度建设几个问题的思考

水银行作为水权租赁和水量买卖双方的中介,是调剂用水余缺、节约水交易成本和促进水资源可持续利用的一个有效工具。水银行制度建设要解决与水资源行政主管部门的关系、规避运作风险及化解交易外部性等三个大问题。作为一个经济组织,水银行要独立于水资源行政主管部门,水资源行政主管部门可以运用行政手段和经济手段来管理水银行,还可以参加水银行交易以满足公共利益的用水需求。在水银行交易出现“空头”,即买入量小于卖出量时,可以运用休耕、水库余水、地下水、节水和水管部门“公开市场业务”等方法来调整,或在出现“空头”之前就采取向卖方预订一定水量的选择权等方法。水交易具有很强的外部性,降低水银行交易外部性的方法有预防性措施和补偿性措施。     

Towards a real-time prediction of waiting times in emergency departments: A comparative analysis of machine learning techniques

Emergency Departments (EDs) can better manage activities and resources and anticipate overcrowding through accurate estimations of waiting times. However, the complex nature of EDs imposes a challenge on waiting time prediction. In this paper, we test various machine learning techniques, using predictive analytics, applied to two large datasets from real EDs. We evaluate the predictive ability of Lasso, Random Forest, Support Vector Regression, Artificial Neural Network, and the Ensemble Method, using different error metrics and computational times. To improve the prediction accuracy, new queue-based variables, that capture the current state of the ED, are defined as additional predictors. The results show that the Ensemble Method is the most effective at predicting waiting times. In terms of both accuracy and computational efficiency, Random Forest is a reasonable trade-off. The results have significant practical implications for EDs and hospitals, suggesting that a real-time performance monitoring system that supports operational decision-making is possible.     

The community impact of school-shootings on stress-related emergency department visits

School-shootings can enormously impact U.S. gun policy, but very little is known about the community mental health impact of school-shootings. We used difference-in-differences and event study analyses to compare stress-related ED visits in zip-codes within 5 miles (exposed) and in zip-codes 10–15 miles from (control) school-shootings before and after school-shootings using data from California, 2005–2011. School-shootings and fatal school-shootings were associated with annual increases of 0.7 and 1.5 stress-related ED visits per 1000 people, increases of 7% and 14%, respectively, compared to pre-shooting utilization. These previously unmeasured costs of school-shootings reinforce calls to prevent gun violence, especially in schools.
