女子短跑运动员月经周期运动能力的初步研究

本文运用“双盲”实验的方法,对短跑运动员在月经周期中运动能力的变化情况进行了研究。发现运动员的运动能力与体内孕酮的浓度呈正相关;与雌二醇的浓度呈负相关。在月经周期三个阶段运动能力在排卵后期最强,其次是月经后期,而排卵期则较差。

基于核心素养的高中数学课程目标与学业评价

基于数学核心素养的课程目标制订,应当以"知识作为核心素养的生成本源"为逻辑线索,以"数学核心素养贯穿课程体系的整体支配模式"为框架,用体现目标水平的层次结构方式,兼顾学业评价的可操作性。对于数学核心素养,宜采用知识理解、知识迁移、知识创新三级水平刻画。知识理解指学生掌握基础知识、形成基本技能;知识迁移指学生将知识应用到新的情境中去解决问题的能力;知识创新指学生提出问题、推广问题的能力。这样划分数学核心素养水平,能反映数学课程目标的内核,具备学业质量测评的操作性特征。     

一流大学建设高校海归教师科研表现自我评价的调查分析

高校海归教师是归国留学人员的重要组成群体,他们知识储备丰富、国际化视野宽广。本研究基于跨文化再适应视角,采用问卷调查的方式,对41所一流大学建设高校的1417名海归教师回国后的科研表现及其主要影响因素进行调查分析。调查结果显示,海归教师对其在课题申报和成果发表方面的评价不高;其在海外学习和工作期间的适应情况、对院系工作氛围的认同程度以及与海外导师、同事或同门开展合作的频率,对海归教师的科研表现具有显著的正向影响。

Childhood Physical Fitness and Performance as Predictors of High School Sport Participation

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.     

Correlates of staff motivation,satisfaction, and job performance of library staff in selected Nigerian University libraries

Abstract

This study examined staff motivation, satisfaction, and job performance among the librarians and library staff in six selected university libraries in Nigeria. The target population for the study includes the professionals and nonprofessional library staff. A total enumeration sampling technique was used to select 180 respondents, which represent the sample for the study. Data was collected using a self-designed questionnaire titled “Staff Motivation, Satisfaction and Job Performance Questionnaire” (SMSJPQ). Six research questions were developed and answered by the study. The results indicate that librarian and library staff are highly motivated with regular pay while the least motivational factor is frequent interaction with their friends. Library staff are primarily satisfied with their jobs when they are in constant link with their friends. Professional library staff significantly experience better work motivation than their nonprofessional counterparts. Significant correlation exists between staff motivation and job performance and between job satisfaction and job performance. In addition, the two factors (motivation and satisfaction) exert significant contribution to the determinant of librarians and library staff job performance. Based on the findings, the study recommended improvement in the level of motivation of nonprofessionals so that the significant difference with the professional counterpart would not be so much pronounced.     

Business Intelligence Capabilities and Firm Performance: A Study in China

The development of artificial intelligence (AI) technology expands the boundary of business practice, inducing the emergence and application of business intelligence (BI) that has promoted the transformation of information techniques to optimize business decision and operation. However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance.
