Research Findings: Research suggests that early care and education programs are most effective when they include strong components of family involvement. The Center for the Study of Social Policy recommended that early care and education programs build family-centered practices to strengthen families and reduce the incidence of child abuse and neglect. This article summarizes a statewide effort to implement this strategy, called Strengthening Families through Early Care and Education. We analyzed program self-assessments submitted by 186 early care and education programs. Analyses revealed that Head Start programs had better support systems in place for families than did “mainstream” (non–Head Start, non-accredited) early care and education programs. Results also showed that a small amount of state and local funding provided enough incentive for programs to improve their family-strengthening practices. Commitment and collaboration at the state level led to a sustainable impact by infusing “strengthening families” concepts into the early care and education field statewide. 相似文献

We designed support for volitional control with four stages for goal initiation (“Want it”), goal formation (“Plan for it”), action control (“Do it”), and emotion control (“Finish it”) based on theories and models of volition. We implemented the support in mathematics courses offered at a community college. We examined the effects of volitional control support on students’ motivation (i.e., intrinsic value, self-efficacy), emotions (enjoyment, pride, anger, anxiety, shame, hopelessness, and boredom), effort regulation, and achievement. We found significant effects of the volitional control support on intrinsic value, enjoyment, anger, anxiety, and boredom. Findings are discussed to improve the design and development of the volitional control support. Limitations and implications of the study are presented as well. 相似文献

This study examined the effects of professional development on teachers’ assessment literacy between two groups of teachers: (1) teachers who were involved in ongoing and sustained professional development in designing authentic classroom assessment and rubrics; and (2) teachers who were given only short-term, one-shot professional development workshops in authentic assessment. The participating teachers taught Year 4 and 5 English, science, and mathematics. The findings showed that the assessment literacy of teachers who were involved in ongoing, sustained professional development had increased significantly during the second year of study. These teachers had also gained a better understanding of authentic assessment. 相似文献

This study investigates the socialization and professional experiences of primary school physical education teachers (PSPETs) in the Asian context of Hong Kong. A qualitative research design is adopted. The researcher used semi-structured interviews, supplemented by documentary sources (diaries) for conducting data collection. Eleven PSPETs participated in this study. Data were analysed through open axial and selective coding. The concepts of organizational sensitivity, sources of satisfaction, dealing with influential persons or critical incidents, status of the profession, educational reform as a trend, and versatile roles are revealed in the theory of ‘Diversified Professionalism’. The substantive theory thus contributes to an increased appreciation of the PSPETs’ work and to the literature on physical education teachers’ professionalization and professionalism. 相似文献

In this paper, we consider the super-twisting observer-based sliding mode control algorithm with fuzzy variable gains (STOSMC) for the fully-actuated hexarotor. Our hexarotor has full actuation due to six titled propellers that allows to control position and orientation (attitude) simultaneously, and resolves the singularity problem of the rotational matrix by using the quaternion modeling framework. We show that the proposed STOSMC for the hexarotor guarantees finite-time convergence of the estimation error and asymptotic stability of the hexarotor. In simulations, we demonstrate the nonsingularity and fully-actuated control performance of the hexarotor by considering extreme position and attitude control scenarios. Moreover, the simulation results show that the hexarotor achieves the fast and precise tracking performance to the desired position and the desired attitude and the chattering phenomenon is reduced compared with the fixed-gains observer-based super-twisting sliding mode control due to the fuzzy mechanism. 相似文献

We study the role of the relationship among inventors and intermediaries in the licensing of university inventions. We suggest that a prior inventor-intermediaries relationship positively influences licensing rates through selective retention of higher quality relationships and mutual learning in the relationship, enabling intermediaries to reduce both information asymmetry and search costs between inventors and potential licensees. We argue that the influence of a prior inventor-intermediaries relationship on licensing is especially important before intellectual property protection is attained and can be substituted by the buyer-side contacts of inventors and intermediaries. We test these predictions using 919 inventions from the technology transfer office at Stanford University. This study has implications for the policies and design of university technology licensing organizations. 相似文献

AbstractIn recent years, volunteering has received strong research attention from both scholars and practitioners. For the most part, involvement in volunteer activities has been identified as an important determinant of future volunteering. Through revalidating an existing instrument, the purpose of this study was to assess the dimensions of volunteer satisfaction at the 2012 London Olympic Games and its impact on future volunteer behaviour. The findings of this study shed light on the identification of volunteer satisfaction factors in the mega sporting event setting, particularly for a unique type of volunteer (i.e. media worker) assigned to a special set of tasks. Unlike Galindo-Kuhn and Guzley’s results that revealed participation efficacy and group integration to be strong predictors of volunteer satisfaction, organizational support was the primary predictor for media centre volunteers’ re-participation intention towards future volunteering programmes. 相似文献

ABSTRACT Research on media substitution theory has examined substitutional and/or complementary relationships between new and existing media. This study focuses on the growth of mobile platforms and investigates the relationship between mobile devices and personal computers. Using Nielsen’s panel data that provide electronically recorded media usage (N = 2,396), this study analyzes yearly changes in time allocation to mobile devices and PCs at total and content-specific usage levels during mobile 4G transition. Results suggest a complementarity dynamic between mobile devices and PCs; however, the patterns were more nuanced in light of the role of individual and structural factors when determining media choice. 相似文献

Many prominent intelligence tests (e.g., Wechsler Intelligence Scale for Children, Fifth Edition [WISC-V] and Reynolds Intellectual Abilities Scale, Second Edition [RIAS-2]) offer methods for computing subtest- and composite-level difference scores. This study uses data provided in the technical manual of the WISC-V and RIAS-2 to calculate reliability coefficients for difference scores. Subtest-level difference score reliabilities range from 0.59 to 0.99 for the RIAS-2 and from 0.53 to 0.87 for the WISC-V. Composite-level difference score reliabilities generally range from 0.23 to 0.95 for the RIAS-2 and from 0.36 to 0.87 for the WISC-V. Emphasis is placed on comparisons recommended by test publishers and a discussion of minimum requirements for interpretation of differences scores is provided. 相似文献

OBJECTIVE: There were two aims: First, to compare children's rates of being battered in home, by peers, and by teachers among students between China and Korea, and second, to identify particular risk factors for such violence. METHODS: Children in grades four through six in Shanghai (238 cases) and Yanji (245 cases) in China and Seoul (248 cases) and Kimpo (241 cases) in Korea were surveyed by questionnaire method. They were asked to complete the Straus' Conflict Tactics Scale and their frequencies in the three situations respectively, and other demographic items. RESULTS: Family violence during the last 1 year was experienced in 70.6% (minor 42.2%; serious 22.6%) of the children in China and 68.9% (minor 9.4%; serious 51.3%) of those in Korea. Experience rates of violence by peers were 42.7% (minor 25.7%; serious 13.7%) in China and 26.0% (minor 11.5%; serious 14.3%) in Korea. Finally, rates of corporal punishment by teachers were 51.1% (minor 28.0%; serious 4.1%) in China and 62.0% (minor 8.8%; serious 43.8%) in Korea. The most important and common risk factor for violence in one situation was the presence of violence in another situation. CONCLUSIONS: The findings indicate that the differences in children's overall experience rates were not particularly striking. However, Korean children experienced more severe forms of violence from family members and from teachers. Findings of risk factors clearly imply that there are children vulnerable to violence from multiple sources. 相似文献
