解析9mm警用转轮手枪橡皮弹的战术性能

9mm警用转轮手枪是中国公安部自主研发的新型武器系统,为满足不同的战术需要,配发有低侵彻的手枪弹和非致命性的橡皮弹。其中9mm橡皮弹的弹头质量2.9g,初速度为110m/s,主要用于制服犯罪分子、驱散非法聚众闹事人群。在目标缺少防护的情况下用9mm警用转轮手枪,在五米内射击头部和胸腹部能够造成严重损伤,不排除危及生命的可能;6到15米射击胸部以下是相对安全的;在20米以外射击的精确度明显下降,可能无法命中目标。     

Is it really performance that is measured？ A reflection of the South African Government＇s performance management system

The institutionalisation of performance management in the South African public service is a post-1994 intervention necessitated by the need to counteract the legacy of poor performance in public service institutions. Performance management as an integrated system is not a standalone intervention, but has direct links with other organisational processes. At both the micro- and macro-levels, PMS （performance management system） recognises institutional performance relationships between individuals＇, teams＇ and departments＇ performance contributions for attaining government performance targets. These institutional performance relationships in the South African public service have attracted excessive attention, whilst their performance impact in communities has been overlooked. In addition, the interdependence between the dichotomies of PMS： institutional performance relationships and performance impact have also been overlooked. In the South African context, this condition creates a disparity in terms of which government employees are rewarded for outstanding performance, whilst targeted beneficiaries express dissatisfaction, often with violent protests, over government＇s performance in the delivery of basic services. The protestors cite poor service delivery in prioritised key performance areas of the South African Government. The granting of performance rewards to government employees is an expression of performance excellence, which should translate into quality service delivery. Such delivery should not only meet the levels of service delivery expectations of targeted communities, but should also result in their total satisfaction. The article is founded on the basis that any disparity between targeted beneficiaries＇ service expectations and level of satisfaction can be linked directly to government progress in PMS implementation.
