高科技企业人才流失预警机制研究   总被引:2,自引:2,他引:0  
以风险信息采集—风险预警指标库构建—风险评估—预警警报发布为逻辑思路阐述高科技企业人才流失风险预警模式。根据对人才流失风险的识别,从个体、组织、环境3个方面构建高科技企业人才流失风险预警指标体系,并利用层次分析法和熵权法对风险指标进行评估。最后,根据BP神经网络原理确定高科技企业人才流失风险预警模型,设计预警模型的构建步骤,进一步对风险等级及临界值进行设计和界定。  相似文献

This paper focuses on a training program in inductive reasoning for first-grade students and presents the direct results as well as the longitudinal effects of the evaluation study. The training is based on Klauer's theory of inductive reasoning and on his “Cognitive training for children” concept (Klauer, 1989a). The training program consists of 120 problems which can be solved through inductive reasoning. The tools for the training exercises were selected to correspond with the age of the targeted cohort. The experimental group in the study consisted of 90 students, whereas the control group was made up of 162. An inductive reasoning test was used in the pre- and posttest as well as in the follow-up study (one year later). The test comprised 33 figural, non-verbal items (Cronbach α = .86). On the posttest, the experimental group significantly outperformed the control group by more than one standard deviation. The experimental group scored significantly higher in each skill area targeted by the training. The most noticeable development was found in system formation. No gender differences were detected on the pre- or the posttest. The effect size of the training program was d = 1.12. In the follow-up study, the experimental group still significantly outperformed the control group; however, their respective levels of development had not changed in this one-year period. Thus, the training effect proved to be stable over time independent of individual students’ original level of inductive reasoning. This study provided evidence that inductive reasoning could be developed very effectively at this early age.  相似文献

为了解家庭教育中“攻击性”这一特征,有针对性地为实施健康家庭教育提供依据,在文献分析、访谈、开放式问卷等方法的基础上收集项目,采用探索性因素分析获得父亲攻击型教养方式七因子模型:督促攻击、默许对朋辈的攻击、责罚、惩罚对长辈的攻击、默许对长辈的攻击、攻击示范、攻击性教养观。此模型在验证性因素分析中得到了验证,具有良好的信度和效度,这对于我国家庭教养方式本土化研究提供了一定理论基础。  相似文献

This study presents evidence regarding the construct validity and internal consistency of the IFSP Rating Scale (McWilliam & Jung, 2001), which was designed to rate individualized family service plans (IFSPs) on 12 indicators of family centered practice. Here, the Rasch measurement model is employed to investigate the scale's functioning and fit for both person and item diagnostics of 120 IFSPs that were previously analyzed with a classical test theory approach. Analyses demonstrated scores on the IFSP Rating Scale fit the model well, though additional items could improve the scale's reliability. Implications for applying the Rasch model to improve special education research and practice are discussed.  相似文献

Based on a qualitative study involving 124 professional and managerial class families in Catalonia (Spain), this paper describes the aims and objectives these families have for the education of their children. During the fieldwork, when asked what they were aiming for in the education of their children, almost all of the parents replied ‘for them to be happy’. But what kind of happiness are they talking about? What kind of education might lead to happiness? Drawing principally on the work of Kellerhals and Montandon and their ‘contractual model of education’ and Bauman’s concepts of ‘secondary security’ and ‘homo eligens’, although also taking into account the related contributions of Lareau, Vincent and Ball, Stefansen and Aarseth, and Kusserow, the paper aims to demonstrate the strong connection these families make between happiness and ‘absolute’ autonomy, understood as two sides of the same coin and seen, by the participants, as the guiding principle that should shape the way they bring their children up.  相似文献

Job satisfaction based on familial and institutional factors was explored for 157 female counselor educators. Results indicate that female associate professors had lower levels of intrinsic rewards domain after controlling for institutional type. Parental responsibility and partnership status were equivocal, with significant interaction effects after controlling for Carnegie Classification.  相似文献

我们知道,幼儿教育跟小学教育是两个不同的领域,它需要不同的教学理念、教学方法和教学手段,但在现实中,幼儿教育的“小学化”倾向正日益严重,不少幼儿园的教学手段尤其是私人幼儿园几乎跟小学一模一样。这种倾向,对于幼儿的健康成长是福还是祸?是喜还是忧,值得家长、幼儿园乃至全社会的深思。  相似文献

在塔里木东北部,甘肃省西部敦煌市柳园镇南侧,有一条近东西向展布的粗面玄武岩带,长度约150kin,宽度达10km,厚度为1900m。这条粗面石玄武岩带属下二叠统哲斯群,岩浆喷发方式以裂隙式溢流为主,枕状构造特别发育。在玄武岩层间夹有很薄的酸性凝灰岩和沉凝灰岩层,属典型的双峰式火山岩组合。按照岩石化学组成的TAS分类命名,主要岩石类型为玄武岩、夏威夷岩和橄榄粗安岩。主要造岩矿物为钠长石(Ab91~100)和普通辉石。普通辉石斑晶、钠长石斑晶和部分基质中的钠长石具有中空结构,并被层状硅酸盐微晶充填。这些岩石基本属碱性玄武岩系列和过渡型系列,大部分属演化的岩浆。演化程度较低的样品具有轻稀土元素亏损型配分曲线,微量元素地球化学具有MORB亲和性,εNd(t)-+10.14~10.89。玄武质岩浆与陆壳物质之间有较轻的同化混染作用。普通辉石、铁钛氧化物的分离结晶作用是岩浆演化的主要机制。玄武质岩浆源区属于软流圈地幔.部分熔融发生于尖晶石稳定域.是软流圈地幔减压(上涌)熔融的产物。  相似文献
