企业人力资源无形损耗探讨     

付兵儿 《宁波职业技术学院学报》2005,9(1):12-14

人力资源无形损耗是企业不容回避的一个现实问题。企业由于诸多原因缺乏及时、有效的补给、维护、保养，使员工的智力素质逐渐退化，加剧了人力资源的无形损耗，影响了员工知识、技能及潜能的发挥。人力资源的维护是用人单位为预防人力资源的损耗，保障人力资源更好地发挥作用，实现用人单位和员工的双赢而事先采取的保障措施。人力资源的无形损耗需要给予补给、保养，才能得到正常的维护。  相似文献

Impact Factors and the Central Limit Theorem: Why citation averages are scale dependent     

Manolis Antonoyiannakis 《Journal of Informetrics》2018,12(4):1072-1088

Citation averages, and Impact Factors (IFs) in particular, are sensitive to sample size. Here, we apply the Central Limit Theorem to IFs to understand their scale-dependent behavior. For a journal of n randomly selected papers from a population of all papers, we expect from the Theorem that its IF fluctuates around the population average μ, and spans a range of values proportional to $\sigma /\sqrt{n}$, where σ² is the variance of the population's citation distribution. The $1/\sqrt{n}$ dependence has profound implications for IF rankings: The larger a journal, the narrower the range around μ where its IF lies. IF rankings therefore allocate an unfair advantage to smaller journals in the high IF ranks, and to larger journals in the low IF ranks. As a result, we expect a scale-dependent stratification of journals in IF rankings, whereby small journals occupy the top, middle, and bottom ranks; mid-sized journals occupy the middle ranks; and very large journals have IFs that asymptotically approach μ. We obtain qualitative and quantitative confirmation of these predictions by analyzing (i) the complete set of 166,498 IF & journal-size data pairs in the 1997–2016 Journal Citation Reports of Clarivate Analytics, (ii) the top-cited portion of 276,000 physics papers published in 2014–2015, and (iii) the citation distributions of an arbitrarily sampled list of physics journals. We conclude that the Central Limit Theorem is a good predictor of the IF range of actual journals, while sustained deviations from its predictions are a mark of true, non-random, citation impact. IF rankings are thus misleading unless one compares like-sized journals or adjusts for these effects. We propose the Φ index, a rescaled IF that accounts for size effects, and which can be readily generalized to account also for different citation practices across research fields. Our methodology applies to other citation averages that are used to compare research fields, university departments or countries in various types of rankings.  相似文献   

Performance differences when using 26- and 29-inch-wheel bikes in Swiss National Team cross-country mountain bikers     

Thomas Steiner  Beat Müller  Thomas Maier  Jon Peter Wehrlin 《Journal of sports sciences》2016,34(15):1438-1444

The purpose of this study was to analyse the effect of bike type – the 26-inch-wheel bike (26“ bike) and the 29-inch-wheel bike (29“ bike) – on performance in elite mountain bikers. Ten Swiss National Team athletes (seven males, three females) completed six trials with individual start on a simulated cross-country course with 35 min of active recovery between trials (three trials on a 26“ bike and three trials on a 29“ bike, alternate order, randomised start-bike). The course consisted of two separate sections expected to favour either the 29“ bike (section A) or the 26“ bike (section B). For each trial performance, power output, cadence and heart rate were recorded and athletes’ experiences were documented. Mean overall performance (time: 304 ± 27 s vs. 311 ± 29 s; P < 0.01) and performance in sections A (P < 0.001) and B (P < 0.05) were better when using the 29“ bike. No significant differences were observed for power output, cadence or heart rate. Athletes rated the 29“ bike as better for performance in general, passing obstacles and traction. The 29“ bike supports superior performance for elite mountain bikers, even on sections supposed to favour the 26“ bike.  相似文献   

军人症状自评量表测评的元分析   总被引：1，自引：0，他引：1  

朱从书 《荆州师范学院学报》2006,29(5):120-122

目的：整合军人症状自评测验的研究结果，探索普遍性结论。方法：通过中国期刊网搜索以SCL-90为工具对军人的调查研究报告，进行元分析。结果：以全国常模为对照组，平均效应值都大于0但较低，以军人常模为对照组，平均效应量都为负值，说明全国常模可能由于年代的原因略偏低、军人常模偏高；军人的精神病性因子分较高。结论：症状自评量表在我国被非常广泛地应用于正常人群，但仍存许多问题需要研究和规范。  相似文献

有奖储蓄中奖号码的计算机分析     

王国钧  戴洪坤 《湖州师范学院学报》1988,(6)

本文根据K.Pearson X~2的检验法,对中国工商银行浙江省分行1981年1月～1987年12月所有的由摇奖机摇出的有奖储蓄的中奖号码,利用电子计算机进行了统计分析.运算结果肯定了中国工商银行浙江省分行目前的摇奖方法是可靠的.也就是说,每个月在全省的某一地、市、县轮流用不同的摇奖机、不同的号珠,由不同的操作人员摇出中奖号码的方法,是行得通的.同时也指出,广大储户完全没有必要去择号购奖券,甚至买好以后再去调换所谓“中意的奖券,因为相对于信度10%而言,我们肯定了假设H:0～9这十个号珠中的每一个被摇奖机摇出的概率是相等的.”  相似文献
