Strategy implementation is important because failure to carry out strategy can cause lost opportunities and leave police officers reluctant to do strategic planning. Lack of implementation creates problems in maintaining priorities and reaching organizational goals. The strategy execution task is commonly the most complicated and time-consuming part of strategic, management. Yet, strategy implementation suffers from a general lack of academic attention. This research paper makes a contribution to police strategy implementation literature by developing a, research model to study the extent of intelligence strategy implementation. 相似文献

We provide an overview of a recently published, edited book in a rapidly emerging field of research, policy, and practice for physical activity: Sedentary Behavior and Health. In this commentary, we highlight the broad perspectives provided in the 27 chapters of Sedentary Behavior and Health and suggest a research strategy to move the field forward—not only with scientific rigor, but also with breadth of scholarship. The book’s chapters provide an overview of the background to and contexts for sedentary behavior and health. They then highlight the importance of understanding health consequences and underlying mechanisms; introduce key measurement technology and analytic strategies; consider sedentary behavior in subpopulations; describe conceptual models and theories to guide sedentary behavior interventions; and explain what is known about interventions in different settings. Considering the breadth of perspectives brought to bear on the field and the plethora of opportunities for research, policy, and practice, we suggest 3 elements of an interdisciplinary research strategy drawing upon the primary knowledge bases of physical activity and health: through the experimental methods of exercise science, through the observational tools of epidemiology, and through the conceptual approaches and methods of behavioral science. A better understanding of the health consequences of sedentary behavior and how they may be influenced can be encompassed by 3 key questions: What changes are needed to most effectively influence sedentary behaviors? What elements of sedentary behavior should be changed to improve health outcomes? What are the feasibility of and the benefits from changing sedentary behavior? 相似文献

Recent experiments on the ski simulator produced ambiguous results and raised unanswered questions concerning the true nature of “novice” behavior and the occurrence of behavioral changes during learning. The aim of the present experiment was to analyze the evolving behavior of three beginners during six practice sessions on a ski simulator. The position of the apparatus platform was recorded as time series and used for constructing dynamical models, including stiffness and damping functions. The results showed that novices tended to exploit a Rayleigh damping behavior during the first trials and then transition toward a van der Pol damping. These results replicate previous observations by Nourrit, Delignières, Caillou, Deschamps, and Lauriot (2003) and suggest the transition to the expert behavior could arise early in practice, when the task is of moderate difficulty. The discussion focuses on the properties of the observed learning dynamics and proposes a global conceptualization for acquiring complex motor skills. 相似文献

摘要：运动承诺可以解释个体是否坚持某个体育行为,为探讨运动承诺与其决定因素之间的关系,同时从调节变量角度,研究不同年龄、不同性别、不同运动类型对运动承诺与其决定因素之间关系的作用,在文献收集的基础上,删选17个研究共20个独立样本,运用CMA2.0软件进行元分析。结果表明,运动乐趣、个人投入、参与机会、社会支持与运动承诺呈中等的正相关,而参与选择与运动承诺呈高度的负相关,社会约束与运动承诺呈中等的负相关。年龄作为运动乐趣、个人投入、参与机会3个因素与运动承诺之间关系的调节变量有统计学意义,运动类型对个人投入、参与机会2个因素与运动承诺的关系有调节作用,性别对运动承诺模型没有调节作用。基于元分析,研究从更宏观的角度考察了运动承诺与其6个决定因素之间的关系,以及调节变量的影响作用。结果也能进一步促进运动承诺理论的本土化研究,以及在休闲体育行为领域的更广泛应用。 相似文献

The determinants of R&D are an important topic of innovation studies. The classical Schumpeterian hypotheses about the influence of size and market power have been complemented with the role played by industry determinants, such as demand pull, technological opportunity and appropriability, in determining R&D investments. However, R&D has always been considered as a whole, even though research and development activities differ in many aspects. We take advantage of a new panel database of innovative Spanish firms (PITEC) to distinguish between research and development efforts of firms. We analyze the differentiated role played by traditional R&D determinants in driving research and development. Results show that demand pull and appropriability have a higher effect on development, while technological opportunity is more influential for research. Differences are statistically significant, important in magnitude, and robust to the use of different indicators for demand pull, technological opportunity and appropriability, and to several robustness checks. 相似文献

根据联合国贸易数据库统计数据,分析了中国高技术产品的贸易现状,采用GL指数、边际产业内贸易指数,从不同角度测度和分析了中国高技术产品的产业内贸易水平,运用面板数据对国家层面的影响因素进行了研究。结果发现,中国高技术产品产业内贸易大而不强,产业内贸易结构不均衡,急需大力发展航空航天等产业。中国与贸易伙伴的人均收入差距、技术差距和外商直接投资都是影响产业内贸易发展的因素,其中人均收入差距和产业内贸易具有显著的负相关性,其余因素根据贸易伙伴的不同而有所差异,并根据研究结果提出了相关建议。 相似文献

企业利润一直以来受到了企业管理者足够的重视,因为利润可以维持一个企业的经营与长期发展。运用中国制造业企业2005—2008年样本,首先分行业检验企业利润率的状况及其变化趋势,其次检验企业利润的主要决定因素,其中对利润的衡量分为利润率和利润规模,最后分析研究企业利润的作用,结果认为:(1)中国制造业企业获得了可观的利润,并且利润率呈现逐年增长的趋势;(2)企业生产率水平、研发支出水平、营业费用支出水平、补贴收入水平都会对企业利润带来促进作用,而企业年龄、出口规模、债务规模、存货规模都会对企业利润产生负向影响;(3)企业利润与研发支出呈现"U"型关系,并且企业利润对生产率具有显著的促进作用,而出口企业的这种促进作用会弱于非出口企业。 相似文献

Fee abolition is said to play a vital role in achieving Universal Primary Education, and in reducing education differentials by gender and wealth. I use DHS data to examine changes in the Net Attendance Ratio (NAR) and the Primary School Completion Rate (PSCR) in sub-Saharan African countries following fee elimination. In countries that abolish fees NARs generally increase more than do PSCRs. NAR differentials in gender and wealth often shrink, while in the same countries corresponding PSCR differentials remain unchanged, or increase. Changes may not coincide with fee abolition. Conflicting results are widely found. Reasons for differing results are discussed. 相似文献
