我国公务员周边绩效的影响因素及其提升对策研究

周边绩效是近年绩效评估研究的重点和热点,绩效影响因素的分析是建立绩效评估指标的基础,也是建立整个评估机制的重要根据。本文通过研究我国公务员周边行为和周边绩效的特点及其内外部影响因素,深化了公务员这一群体的周边绩效理论,明确了我国公务员周边绩效的影响因素,提出了提高我国公务员周边绩效的建议,可使周边绩效在我国公务员的绩效管理中得到合理关注,发挥其应有的价值和作用。     

澳大利亚绩效审计发展新趋势

本文以澳大利亚审计署网站最新资料为研究样本,利用文本分析法对绩效审计相关信息进行理论识别与系统分析,揭示澳大利亚绩效审计在广度和深度方面的突破趋势:在审计内容、审计过程、审计脉络、审计范畴和审计内涵等方面,集中展现绩效审计的系统功能;通过加强绩效审计主体的制约力量、保证扩大绩效审计对象范围落实到位、增强绩效审计的资金和技术支撑等举措,不断加强绩效审计的组织建设;在持续完善绩效审计的过程控制体系方面,不断完善绩效审计的基本法律法规、持续推进绩效审计过程的标准化管理和重视绩效审计的质量认证机制等特征最为突出。文章最后就澳大利亚绩效审计发展趋势对我国绩效审计发展的启示与借鉴进行了阐释。     

公共政策评估多元模式的困境及其解决的哲学思考

通过对政策评估模式发展的历史考察,文章分析了政策评估模式由单一向多元转变的逻辑以及多元评估模式的困境。并以南水北调移民政策评估为例,解读了当今多元理性下的政策评估仍然存在的多元利益界定不准确、评估模式结构固化等诸多问题。要从根本上解决多元理性下政策评估模式的问题,必须实现政策评估哲学思维的进一步转变,而这一转变应遵循批判性政策分析理论、利益相关者理论以及理性选择理论的基本价值。     

甘肃城乡一体化：现状与未来

城乡一体化作为我国一项新的发展战略,对城乡二元结构突出、基础条件偏弱、经济总量偏小、人均水平偏低的甘肃来说,既是难得的大好机遇,但也充满挑战。通过构建甘肃省城乡一体化的综合评价指标体系评价反映出甘肃省的城乡一体化有一定程度的发展,但也存在发展动力挖掘不够、产业结构单一、农村贫困率高、社会力量动员不足等问题。区域发展是嵌入在特定的社会文化背景之中的,进行文化上的足够动员、培育区域文化软实力是甘肃推进城乡一体化的关键所在。     

标签理论在高校学生评价体系中的应用

标签理论作为社会工作的重要理论,对高校学生评价体系的有效开展也具有同样重要的意义。如何正确运用高校学生评价中的标签对学生的健康发展就显得尤为重要。作为高校教育者不仅应懂得善于给学生张贴积极标签,还应懂得如何避免消极标签的负面效应,从而促进大学生的健康全面发展。     

Performance Management in Australia's Public Mental Health Service: A State Based Perspective

This article investigates the implementation of key performance indicators (KPIs) in Western Australia's public mental health system. A nationally agreed performance measurement framework forms part of the much needed reform now taking place within Australia. However, progress in the effective monitoring and reporting of KPIs is slow in most states, including Western Australia. The authors report on the results of a selective case study involving semi‐structured interviews with mental health administrators and offer a more nuanced insight into the intricacies and difficulties involved in performance measurement reform. The principal finding is that effective performance measurement and reporting can be internally problematic, particularly within a fragmented and networked system. This tends to give rise to a conformance‐only approach to performance measurement.     

Evolution of the content of THC and other major cannabinoids in drug-type cannabis cuttings and seedlings during growth of plants

In Europe, authorities frequently ask forensic laboratories to analyze seized cannabis plants to prove that cultivation was illegal (drug type and not fiber type). This is generally done with mature and flowering plants. However, authorities are often confronted with very young specimens. The aim of our study was to evaluate when the chemotype of cannabis plantlets can be surely determined through analysis of eight major cannabinoids content during growth. Drug-type seedlings and cuttings were cultivated, sampled each week, and analyzed by high-performance liquid chromatography with diode array detection. The chemotype of clones was recognizable at any developmental stage because of high total Δ(9)-tetrahydrocannabinol (THC) concentrations even at the start of the cultivation. Conversely, right after germination seedlings contained a low total THC content, but it increased quickly with plant age up, allowing chemotype determination after 3 weeks. In conclusion, it is not necessary to wait for plants' flowering to identify drug-type cannabis generally cultivated in Europe.
