浅析摔跤运动员的营养需求及对策

运动员运动成绩的提高,有赖于"运动、营养、休息"三者之间的动态平衡。要想成为一名优秀的摔跤运动员,必须具备举重运动员的力量,技巧运动员的灵敏,长跑运动员的耐力和象棋运动员的天才战术思想,因此运动员对能源物质要求较高。根据摔跤运动项目的特点,通过查阅大量的文献资料,从运动员的生理特点以及对营养的需求等方面,对摔跤运动的营养需要、存在问题及对策进行了初步的分析和探讨。     

当前我省警务实战训练存在的主要问题及对策

当前,我省在开展警务实战训练中存在着实战观念缺乏、针对性训练不足、综合实战训练效果不明显以及工训矛盾和训练经费投入不足等问题。要解决这些问题,应从强化思想教育、进一步完善训练保障、重视教官队伍建设、进一步改进教学训练方法与内容和推行"战训合一、轮值轮训"的训练模式等几个方面入手加以解决,确保警务实战训练的正常开展,从而提高训练绩效。

论农村基层民主建设中的几个辩证关系

新中国60年,农村基层民主建设获得了巨大的进步,但也还存在许多改进的空间,若要进一步解放农村的民主动力,必须以辩证的思维正视＂治＂与＂乱＂之争、＂进＂与＂退＂之思、＂政＂与＂民＂之辨、＂上＂与＂下＂之衡、＂刚＂与＂柔＂之合,从认识和实践上解决一系列难题。     

Focused Deterrence Strategies and Crime Control

Research Summary

Focused deterrence strategies are increasingly being applied to prevent and control gang and group‐involved violence, overt drug markets, and individual repeat offenders. Our updated examination of the effects of focused deterrence strategies on crime followed the systematic review protocols and conventions of the Campbell Collaboration. Twenty‐four quasi‐experimental evaluations were identified in this systematic review. The results of our meta‐analysis demonstrate that focused deterrence strategies are associated with an overall statistically significant, moderate crime reduction effect. Nevertheless, program effect sizes varied by program type and were smaller for evaluations with more rigorous research designs.

Policy Implications

The available empirical evidence suggests these strategies generate noteworthy crime reduction impacts and should be part of a broader portfolio of crime reduction strategies available to policy makers and practitioners. Investments still need to be made, however, to strengthen the overall rigor of program evaluations and improve our understanding of key program activities associated with observed crime reduction impacts.     

高职院校要重视和加强大学生择业观教育——以秦皇岛市高职院校为例

受当今社会文化观和价值观多元化的影响,高职院校学生择业观存在过于限定自身择业地域和就业单位、过多重视薪酬福利、对自己的认识和评估不准确、择业准备不充分等问题。学生择业价值观不正确、学校对学生就业方面指导不足、政府相关政策和经济发展环境的影响是造成这些问题的主要原因。为此,应通过以下五个方面加强大学生择业观教育：一是放宽户籍限制,促进人才流动;二是合理调整薪酬期望值,正确看待教育的投入产出;三是加强学生的价值观教育;四是建立全程的就业指导模式;五是鼓励学生积极参与实践。     

我国《农业保险法》的立法构想

我国农业保险的法律规制现状与立法的预期利益凸显了《农业保险法》立法的必要性。《农业保险法》的基本原则为:政府适度干预、合理补贴、强制保险与自愿保险相结合。我国未来的《农业保险法》至少应包括三方面的内容:农业保险合同制度、农业保险经营管理制度和农业保险责任制度。     

结构性问题破解与社会管理创新——基于社会结构视角的分析

当代中国社会问题大多都源于结构性问题。结构性视角可以成为分析和破解中国社会问题的一个有益视角。社会结构性问题的破解．社会结构性矛盾的解决,要求创新社会管理思路。社会管理创新是我国社会发展进程中的深刻变革,也是经济社会发展到一定阶段、社会经历了结构性变迁之后的必然抉择。社会管理创新的基本路径是有序推进社会结构性改革,培育公民社会和社会组织,注重公共服务型政府建设,最终建构出以公正为基础的三维制衡的现代社会结构。     

Book Reviews

Using a sample of full-time employees of a public sector organisation in South Korea, this study examines whether transformational leadership (TL) has a significant positive effect on affective commitment (AC) and organisational citizenship behavior (OCB), and whether AC is positively related to OCB. The study also examines whether AC mediates the effects of TL on OCB. The results of higher-order structural equation modeling indicate a positive relationship between TL and AC; no significant relationship between TL and OCB; and a significant positive relationship between AC and OCB. Thus, the results clearly demonstrate that AC fully mediates the relationship between TL and OCB. Theoretical and practical implications of these findings are discussed, and proposals for future research are made.     

An Exploratory Examination of a Gendered Model of the Effects of Role Stressors

A gendered model of the effects of role stressors on job stress, job satisfaction, and organizational commitment was tested. Ordinary least squares regression analysis of survey data from correctional staff provided partial support for the proposition that men and women perceive and respond to the work environment differently. Work–family conflict was found to influence levels of job stress, job satisfaction, and organizational commitment among women but not among men. Conversely, role ambiguity, role overload, and perceived dangerousness influenced levels of job stress for men but not women. Furthermore, levels of role conflict and role ambiguity influenced levels of job satisfaction for men but not for women. These findings lend support to further development of gendered theoretical models.
