Behaviors emerge, in part, from the interplay of infant abilities and caregiver–infant interactions. Cross‐cultural and developmental studies suggest caregiver handling and positioning influence infant development. In this prospective, longitudinal study, the effects of 3 weeks of enhanced handling and positioning experiences provided to 14 infants versus control experiences provided to 14 infants at 2 months of age were assessed with follow‐up through 15 months of age. Behaviors in prone were immediately advanced. Short‐term advancements occurred in multiple behaviors, including prone, head control, reaching, and sitting behaviors. Longer term advancements, up to 12 months after the experience period, occurred in object transfer, crawling and walking behaviors. This suggests broad and long‐lasting changes can arise via brief periods of change in caregiver–infant interactions. 相似文献

Tree-structured vector quantization (VQ) is a technique designed to represent a codebook that simplifies encoding as well as vector quantizer design. Most design algorithms for tree-structured VQ used in the past are based on heuristics that successively partition the input space. Recently, Chou, Lookabaugh and Gray proposed a tree-pruning heuristic in which a given initial tree is pruned backwards according to certain optimization criterion. We define the notion of an optimal pruned tree subject to a cost constraint and study the computational complexity of finding such an optimal tree for various cost functions. Under the assumption that all trees are equally probable, we show that, on the average, the number of pruned trees in a given tree is exponential in the number of leaves. Furthermore, we prove that finding an optimal pruned tree subject to constraints such as entropy or the expected-depth is NP-hard. However, we show that when the constraint is the number of leaves, the problem can be solved in polynomial time. We develop an algorithm to find the optimal pruned tree in O(nk) time, where n is the size of the initial tree and kis the constraint size. 相似文献

ABSTRACTThe purposes of the study were to assess the effects of an online learning module on the implementation of mand training by a classroom team and determine whether training improved manding for a student with multiple disabilities. The classroom team utilized the Support Needs Assessment and Planning (SNAP) process to identify supports and guide implementation of the mand training procedures. The results indicate that both the special education teacher and paraprofessional were able to implement the mand training strategy with fidelity after completing the online module and student manding increased. The classroom team reported that both the online learning module and SNAP process were valuable for planning and implementing research-based supports. Limitations, implications for practice, and future research considerations are addressed. 相似文献

Questionnaire data from 137 panel chairs at the 2003 Academy of Criminal Justice Sciences meeting in Boston reveal respondent perceptions of the conference site, overall impressions of the conference, as well as panelist attendance, and the quality of information presented by panelists. The findings reveal high marks for the conference space, hotel rooms, and the city of Boston itself, resulting in an overall positive conference experience, but responses also highlight several areas of concern, including panelist attendance problems and presentation etiquette. Recommendations are provided, which may foster positive, incremental change at future ACJS annual meetings. 相似文献

Service-learning (S-L) has been regarded as a relatively well-established and effective teaching pedagogy. Students who participate in S-L are more likely to learn more efficiently, more effectively, and remember more of what they have learned than their counterparts. Current studies have been done on the experiences of students in service-learning and implementing S-L components. Other research has focused on the barriers to conducting effective S-L. However, no qualitative studies have examined a faculty component of S-L. Also, there have been few studies or discussions delineating faculty perceptions or experiences in S-L. An e-mail survey supplemented with personal interviews was utilized in an effort to understand experiences of participating in S-L. Of specific interest were faculty perceptions of the costs and rewards in employing S-L in gerontology-related curriculums. 相似文献
