Understanding trends in neighborhood child maltreatment rates: A three-wave panel study 1990–2010     

《Child abuse & neglect》2018

This study examines how changes in the social and economic structure of neighborhoods relate to changes in child maltreatment report rates over an extended period. The panel study design allows us to partition the changes in child maltreatment report rates into a portion associated with how the levels of socio-economic risk factors have changed over time, and a portion related to how the relative importance of those factors in explaining maltreatment report rates has changed over time. Through the application of fixed effects panel models, the analysis is also able to control for unmeasured time-invariant characteristics of neighborhoods that may be a source of bias in cross-sectional studies. The study finds that increases in vacant housing, single parent families and unemployment rates are strongly associated with increases in child maltreatment report rates. Changes in racial/ethnic composition did not produce changes in maltreatment report rates except when they reached extreme levels of segregation. Although poverty rates were predictive of cross-sectional variation in child maltreatment, increases in neighborhood poverty became less associated with increases in child maltreatment report rates over time.  相似文献   

环境规制的节水效应分析——基于正式环境规制与非正式环境规制的视角     

尹庆民  李田田 《科技管理研究》2019,39(8)

为从根本缓解水资源对工业发展的束缚,反思现有环境规制政策能否有效实现节水效应。基于脱钩测度模型和面板门槛模型,分别验证正式环境规制与工业用水以及非正式环境规制与工业用水的关系,进一步引入正式与非正式环境规制的交互项进行分析。结果表明:环境规制与工业用水量处于从“震荡波动”到“持续脱钩”的状态,工业用水量随着环境规制的变化出现平稳或者减少的趋势。正式和非正式环境规制与工业用水量之间都呈倒U型曲线关系,用水库兹涅茨曲线存在。此外,正式环境规制与非正式环境规制之间存在双向传导路径,相互促进对方对工业用水的作用效果。因此,政府需要强化对非正式环境规制的重视,增强环境规制工具的节水效应,促进工业企业的转型升级。  相似文献   

浅析农村幼儿园平衡膳食实施的有效策略     

柴玉花 《天津教育》2021,(11):166-167,170

幼儿园作为幼儿膳食的主要提供者,主要负责研究营养搭配是否合理、营养素是否全面均衡、膳食质量是否优质等问题。面对越来越多的营养失衡幼儿,实施营养配餐刻不容缓,而只有平衡膳食才是把《中国居民膳食指南》真正落实到幼儿餐盘内的唯一途径,这对缺乏专业人士指导科学配餐的农村幼儿园尤为重要。  相似文献

基于平衡计分卡的高校新文科建设管理模式研究          下载免费PDF全文

马勇  刘荣增  张道庆 《上海教育评估研究》2021,10(3):48-53

2019-2021年,教育部将分 3年全面实施“六卓越一拔尖”计划 2.0,该计划要求高校紧扣时代新要求、经济社会发展新实践和科技革命新进展,积极推进新文科建设。对高校来说,新文科建设具有较强的动态复杂性,它需要在当前与未来、过程与结果、局部和整体之间形成动态平衡。为了有效地推动新文科建设,对新文科建设实施目标管理,并把建设计划转化为高校的日常具体管理行为,高校可充分利用平衡计分卡这种战略计划管理工具,协调新文科建设各相关主体的行为,实现新文科建设目标的动态平衡。  相似文献   

An empirical investigation of information sharing behavior on social commerce sites     

《International Journal of Information Management》2016,36(5):686-699

Social commerce sites (SCSs), a new model of social media, provide fertile ground for customers to communicate their opinions and exchange product- or service- related information. Given the significant opportunities related to the use of social media data for customers’ insight, we explore the factors driving information sharing behavior on SCSs. In this paper, we propose and empirically test a comprehensive theoretical model for customer information sharing behavior through analysis of online survey data as well as network and behavioral usage data of over four months from 1177 customers in a SCS. The research model was empirically validated with the use of both subjective and objective data in a longitudinal setting. Our results show that customer information sharing is influenced by both individual (i.e., reputation and the enjoyment of helping others) and social capital (i.e., out-degrees’ post, in-degrees’ feedback, customer expertise and reciprocity) factors. This study contributes to the existing literature by highlighting the role of directed social network in customer information sharing behavior on SCSs. We believe that the results of our study offer important insights to the IS research and practice.  相似文献   

Developing a performance management framework for a national sport organisation     

《Sport Management Review》2015,18(2):308-316

Organisational performance has become an imperative management function within the non-profit sport context as increased pressure is placed on these organisations to provide a quality service to stakeholders in an accountable and transparent manner. The case presented here examines the issue of developing and implementing a robust performance management tool that can potentially help national sport organisation managers with the multitude of performance challenges now facing these organisations. The theoretical underpinnings of a performance management tool are presented followed by background information to a fictional national sport organisation (Racquetball Australia) and views from the CEO of the organisation in relation to the topic of performance management. The case is written from a fictional perspective so that instructors may adapt the case to suit the geographical context in which the class is taking place.  相似文献

随着教育信息化的发展,高校门户网站的建设和管理也得到了增强。高校网站作为高校内外服务的窗口,其运行好坏直接关系到高校的管理水平和公众形象。在高校网站的运行建设中,高校网站的评价是不可缺少的一个重要环节。平衡记分卡作为战略绩效管理工具已广泛应用于企业管理中,对高校网站的绩效评价也有较好的借鉴意义。发挥平衡记分卡的优势,搭建高校网站绩效评价体系,能够提升高校网站的管理水平。  相似文献   

我国医药上市公司研发资金投入强度影响因素的实证研究——基于A股上市公司面板数据     

杨慧  宫妍  陈玉文 《科技管理研究》2017,(16)

基于2011—2015年我国医药上市公司年报数据,运用STATA 14.0进行面板回归分析,实证分析资本结构、企业规模、股权结构、研发人员投入、研发知识产出等因素对医药上市公司研发资金投入强度的影响,为提升医药上市公司研发投入水平提供参考。结果显示,企业规模、股权结构中股权制衡度、研发人员投入、研发知识产出均与医药上市公司研发资金投入强度呈显著正相关关系,资本结构、股权结构中股权集中度均与医药上市公司研发资金投入强度无显著相关关系。通过适当的扩大企业规模、增加研发人员投入、完善专利保护制度,促进研发成果高效率转化、合理分配股权结构等手段提高我国医药上市公司研发资金投入水平。  相似文献   

我国农业区水资源-能源-粮食系统协调适配与农业产出——基于人力资本门槛效应的实证     

陈军飞  晏霄云 《科技管理研究》2020,40(5):215-223

基于2012—2016年我国40个农业区域的面板数据,在考虑人力资本差异的情况下,建立耦合评价模型和面板门槛模型,测度农业区水资源-能源-粮食(WEF)三大主要资源的协调适配程度,并以此为基础,探索WEF系统的协调适配对农业产出的影响。研究发现,(1)我国大部分农业区WEF系统处于临界适配区或耦合失谐区,整体上投入产出存在不匹配的现象,投入要素冗余严重,资源配置效率偏低。(2)WEF系统协调适配与农业产出存在双重门槛,只有当农业从业人员达到较高教育水平时,WEF系统的协调适配对农业产出呈现显著的促进作用。  相似文献
