Global health is becoming an increasingly important component of medical education. Medical libraries have an opportunity to assist global health residents with their information needs, but first it is important to identify what those needs are and how best they can be addressed. This article reports a collaboration between global health faculty and an academic medical librarian to assess the information needs of global health pathway residents and how assessment data are used to create a multicomponent program designed to enhance global health education. 相似文献

The spatial locative words used in multiword locative action expressions were tracked longitudinally for 4 children. Children ranged in age from 1–5 to 3–0. Although certain words emerged before others, as previous research has shown, the children were selective about which lexical categories were used to talk about movement events, and their selections changed systematically with age. Source and path words were used most frequently at the earliest ages, and goal words predominated at the oldest ages. The children also increased the specificity with which they talked about locative movement events by combining goal words with source and path words as they got older. The observed developmental shifts in lexical use suggest that lexical acquisition is influenced not only by the meaning of the individual locative words but also by the verb relational roles that such words play when embedded in semantic/syntactic contexts. 相似文献

The author makes some very specific and rather bold suggestions to supervisors of instruction. His suggestions should also be helpful to other people with supervisory responsibilities, such as administrators, department heads, and supervising teachers. 相似文献

Studies have reported an inverse association between language development and behavioral inhibition or shyness across childhood, but the direction of this association remains unclear. This study tested alternative hypotheses regarding this association in a large sample of toddlers. Data on behavioral inhibition and expressive and receptive language abilities were collected from 816 twins at ages 14, 20, and 24 months. Growth and regression models were fit to the data to assess the longitudinal associations between behavioral inhibition and language development from 14 to 24 months. Overall, there were significant associations between behavioral inhibition and expressive language, and minimal associations with receptive language, indicating that the association is better explained by reticence to respond rather than deficient language development. 相似文献

The driving force in the pursuit for quantum computation is the exciting possibility that quantum algorithms can be more efficient
than their classical analogues. Research on the subject has unraveled several aspects of how that can happen. Clever quantum
algorithms have been discovered in recent years, although not systematically, and the field remains under active investigation.
Richard Feynman was one of the pioneers who foresaw the power of quantum computers. In this issue dedicated to him, I give
an introduction to how particle and wave aspects contribute to the power of quantum computers. Shor’s and Grover’s algorithms
are analysed as examples. 相似文献

Preschoolers’ conceptual understanding and procedural skills were examined so as to explore the role of number‐words and concept–procedure interactions in their additional knowledge. Eighteen three‐ to four‐year‐olds and 24 four‐ to five‐year‐olds judged commutativity and associativity principles and solved two‐term problems involving number words and unknown numbers. The older preschoolers outperformed younger preschoolers in judging concepts involving unknown numbers and children made more accurate commutativity than associativity judgements. Children with conceptual profiles indicating a strong understanding of concepts applied to unknown numbers were more accurate at solving number‐word problems than those with a poor conceptual understanding. The findings suggest that an important mathematical development during the preschool years may be learning to appreciate addition concepts as general principles that apply when exact numbers are unknown. 相似文献

The relationship between bowling action classification and three-dimensional lower trunk motion in fast bowlers in cricket 总被引:1,自引:1,他引:0
Lower back injuries, specifically lumbar stress fractures, account for the most lost playing time in professional cricket. The aims of this study were to quantify the proportion of lower trunk motion used during the delivery stride of fast bowling and to examine the relationship between the current fast bowling action classification system and potentially injurious kinematics of the lower trunk. Three-dimensional kinematic data were collected from 50 male professional fast bowlers during a standing active range of motion trial and three fast bowling trials. A high percentage of the fast bowlers used a mixed bowling action attributable to having shoulder counter-rotation greater than 30 degrees. The greatest proportion of lower trunk extension (26%), contralateral side-flexion (129%), and ipsilateral rotation (79%) was used during the front foot contact phase of the fast bowling delivery stride. There was no significant difference in the proportions of available lower trunk extension, contralateral side-flexion, and ipsilateral rotation range of motion used during fast bowling by mixed and non-mixed action bowlers. Motion of the lower trunk, particularly side-flexion, during front foot contact, in addition to variables previously known to be related to back injury (e.g. shoulder counter-rotation), should be examined in future cross-sectional and prospective studies examining the fast bowling action and low back injury. 相似文献
