The quality of experiences in childcare has significant, lasting impact on children&s social development. With the growing number of young children being served in family childcare settings, it is imperative that the care provides a quality environment that nurtures children&s social development. Empirically supported interventions that specifically target family childcare, however, are lacking. The development and evaluation of a video-based program aimed at training family childcare providers in setting up their childcare environment to promote social development in young children is described. Forty-two family childcare providers were randomly assigned to an intervention group and a wait-list control group. A majority of the participants felt they learned some to very much new, practical information and said they found the interactive discussions particularly helpful. This study illustrates the feasibility of doing training and evaluation research in family childcare settings. 相似文献

Charter schools that target underserved communities, including Latinxs, have proliferated in the U.S., claiming a unique, more autonomous and successful alternative to traditional public schools, often with a promise of increased postsecondary access and preparation. However, there is conflicting evidence regarding their effectiveness on academic outcomes, prompting additional research on charter schools. This study examined the college access and preparation experiences of 14 Latinxs attending college preparatory charter schools within one school system in Texas. Findings highlight how schools assisted students in preparing for college, but challenges in accessing college knowledge and assistance still existed, particularly for undocumented students. 相似文献

道德规范与图书馆事业 总被引：1，自引：0，他引：1
美国图书馆协会的《职业道德规范声明》提出了以图书馆事业为中心的具体原则,其《图书馆权利法案》则明确了图书馆的责任和义务。目前,美国社会和政治环境的变化为图书馆职业带来了越来越多的忧虑和压力。"9·11"后出台的《爱国者法案》明显与图书馆职业道德规范中所阐述的重要原则相冲突。因此,美国图书馆协会决心抵制《爱国者法案》对知识、信息自由开放以及行使个人隐私权的限制。 相似文献

Natural language speech enabled systems are an attractive option for in-car infotainment. Differences in cultural expectations in communication, however, can pose difficulties for interface developers and cause frustration for users. We adopt the perspective of cultural discourse theory to analyze 26 drivers interacting with an in-car speech interface. We focus here on directive sequences and the phenomenon of participants using non-task talk. The analysis of these sequences reveals a norm that one ought to engage in non-task talk with the system. We suggest that this norm is grounded in a user premise that the system’s interactional status involves the ability to speak. We find that this norm lacks crystallization among participants, and we formulate a competing norm that helps to account for this. The second norm reveals an underlying belief that the system’s status as a machine is the basis for how it should be treated. 相似文献

Research methods are perhaps the most difficult subject matter to teach in the graduate criminal justice curricula. This is in part due to the mix of practitioners and aspiring researchers in most criminal justice graduate departments, leading many instructors to question whether their own coverage is in line with the needs of their graduate students as well as the coverage of other instructors. Also complicating matters is that research methods textbooks are not geared specifically for the graduate level, and thus may neglect topics that are necessary for today's criminal justice graduate students. The present study addresses these concerns by providing an analysis of 11 current criminal justice research methods textbooks, as well as a survey of 36 instructors of graduate criminal justice and criminology research methods classes. Both the texts and instructors are found to place a strong focus on quantitative methods, while the textbooks tend to place a greater emphasis on qualitative methods than the instructors. Moreover, both the texts and instructors neglect topics crucial to today's criminal justice graduate student, including grant writing, article writing and critiquing, and standards for collaborative research efforts. 相似文献

What if new cars could adjust in-car devices to particular ways of speaking around the world? General Motors sought communication research to inform the design of culturally competent in-car human–machine interfaces. We discuss concerns and tensions that arise when balancing commitments of naturalistic study with design development goals. We emphasize the importance of awareness, attentiveness, and cooperation to ensure research integrity. 相似文献

Numerous studies have been conducted worldwide about loneliness in older adults living in nursing homes and the factors associated with it. However, only a few studies have focused on social factors that may predispose these older adults to experience loneliness. The purpose of this study was to examine the interplay between and among loneliness, social isolation, social engagement, and life satisfaction among Filipino elderly (n = 180) recruited from government and nongovernment nursing homes in the Philippines. A multiaspect questionnaire, which included the UCLA Loneliness Scale, Revised Index for Social Engagement, Friendship Scale, and Life Satisfaction for the Third Age-Short Form was used to gather the needed data and information. Results of single and multiple regression analyses indicate an effect of the three factors (social isolation, social engagement, and life satisfaction) on loneliness with social isolation having the greatest impact on loneliness. Notably, increased social isolation, inadequate social engagement and decreased life satisfaction consequently aggravate loneliness. Social engagement produced a positive effect to both social isolation and life satisfaction in a way that a decrease in social engagement will decrease life satisfaction and increase social isolation. On the whole, loneliness in geriatric nursing homes is evident, and it is shaped by social isolation, social engagement and life satisfaction. Impliedly, interventions and measures to minimize loneliness are necessary, and further research is needed to explore other variables contributing to loneliness in geriatric nursing homes. 相似文献

In this paper, a new approach to robust H∞ filtering for a class of nonlinear systems with time-varying uncertainties is proposed in the LMI framework based on a general dynamical observer structure. The nonlinearities under consideration are assumed to satisfy local Lipschitz conditions and appear in both state and measured output equations. The admissible Lipschitz constants of the nonlinear functions are maximized through LMI optimization. The resulting H∞ observer guarantees asymptotic stability of the estimation error dynamics with prespecified disturbance attenuation level and is robust against time-varying parametric uncertainties as well as Lipschitz nonlinear additive uncertainty. 相似文献
