OBJECTIVE: To identify reliable, inexpensive predictors of foster care placement disruption that could be used to assess risk of placement failure. METHODS: Using the Parent Daily Report Checklist (PDR), foster or kinship parents of 246 children (5-12 years old) in California were interviewed three times about whether or not their foster child engaged in any of the 30 problem behaviors during the previous 24 h. PDR was conducted during telephone contacts (5-10 min each) that occurred from 1 to 3 days apart at baseline. Disruptions were tracked for the subsequent 12 months. Other potential predictors of disruption were examined, including the child's age, gender, and ethnicity, the foster parent's ethnicity, the number of other children in the foster home, and the type of placement (kin or non-kin). RESULTS: Foster/kin parents reported an average of 5.77 child problems per day on the PDR checklist. The number of problem behaviors was linearly related to the child's risk of placement disruption during the subsequent year. The threshold for the number of problem behaviors per day that foster and kinship parents tolerated without increased risk of placement disruption for these latency-aged children was 6 or fewer. Children in non-kin placements were more likely to disrupt than those in kinship placements. There was a trend for increased risk of disruption as the number of children in the home increased. CONCLUSIONS: The PDR Checklist may be useful in predicting which placements are at most risk of future disruption, allowing for targeted services and supports.  相似文献   

A History of Ways of Seeing the Land: Environmental History at the National Museum of Australia     

Mike Smith 《Curator: The Museum Journal》2003,46(1):7-14

One of the distinctive features of the National Museum of Australia is the prominent role of environmental history in the Museum's programs and in its organizational structure. Environmental history is a field that operates best at the boundaries of science and the humanities, where the natural sciences and social history meet. The National Museum is one of few museums that facilitate this, drawing historians, geographers, archaeologists, earth scientists, and biologists into program development as members of the one curatorial and design team. This article discusses the advantages of environmental history as a strategic focus for the Museum, and looks at one of its major exhibitions.  相似文献

Young Children's Spatial Representations Developed through Exploration of a Desktop Virtual Reality Scene     

Silvia Gabrielli  Yvonne Rogers  Mike Scaife 《Education and Information Technologies》2000,5(4):251-262

Virtual Reality (VR) technology seems to offer the opportunity of designing 3D worlds and navigation activities which provide settings that are close to children's everyday experiences, capitalising on their enthusiasm for videogame-like technologies.This paper describes how different types of exploration of a VR scene by 6[emsp4 ]y-old children affected their performance in a series of spatial tasks. Individual children explored a desktop virtual world where we varied both the visual perspective on the VR scene (route vs. survey view) and the level of exploration control (active vs. passive movement). We measured children's knowledge of the spatial layout of the environment through their memory of objects' location in the virtual scene and through the analysis of their wayfinding abilities within the scene.The results indicate that children were able to develop and display different levels of allocentric knowledge about the virtual world depending on the way they had familiarized with it and on the characteristics of the task demands. This finding contributes to inform the design of VR technologies aimed at supporting or evaluating spatial abilities in children of this age.  相似文献   

Who is using the .co.uk domain? Professional and media adoption of the web     

Mike   《International Journal of Information Management》2000,20(6)

This paper reports on a survey of 221 web sites chosen at random from a subset of the .co.uk area of the Internet. A breakdown of the types of business represented shows that whilst computing companies continue to have a sizeable presence on the web, certain other types of business now also have a relatively large number of sites. The survey found many media-related businesses and professional-based companies and practices, reflecting the increasing use of Information Technology in these areas but also the increasing knowledge about the Internet that is needed or helpful in many types of job. The results are consistent with general business use of the web in the UK still being in an experimental phase of web site creation by those who can rather than by those who should.  相似文献   

The effect of badminton-specific exercise on badminton short-serve performance in competition and practice climates

This study examined the effects of changes in physiological and psychological arousal on badminton short-serve performance in competitive and practice climates. Twenty competitive badminton players (10 males and 10 females) volunteered to participate in the study following ethics approval. After familiarisation, badminton short-serve performance was measured at rest, mid-way through and at the end of a badminton-specific exercise protocol in two conditions; competition vs. practice. Ratings of cognitive and somatic anxiety were assessed at three time points prior to badminton short-serve performance using the Mental Readiness Form 3. Heart rate and rating of perceived exertion (RPE) were assessed during the exercise protocol. Results indicated that better short-serve performance was evident in practice compared to competition (P?=?.034). RPE values were significantly higher in the competition condition compared to practice (P?=?.007). Cognitive anxiety intensity was significantly lower post-exercise in the practice condition compared to competition (P?=?.001). Cognitive anxiety direction showed greater debilitation post-exercise in the competition condition compared to practice (P?=?.01). Somatic anxiety intensity increased from pre-, to mid- to post-exercise (P?=?.001) irrespective of condition. This study suggests that badminton serve performance is negatively affected when physiological arousal, via badminton-specific exercise, and cognitive anxiety, via perceived competition, are high.  相似文献   

The effects of barbell load on countermovement vertical jump power and net impulse     

Peter D. Mundy  Neal A. Smith  Mike A. Lauder  Jason P. Lake 《Journal of sports sciences》2017,35(18):1781-1787

The aim of this study was to examine the effects of barbell load on countermovement vertical jump (CMJ) power and net impulse within a theoretically valid framework, cognisant of the underpinning force, temporal, and spatial components. A total of 24 resistance-trained rugby union athletes (average ± SD: age: 23.1 ± 3.4 years; height: 1.83 ± 0.05 m; body mass (BM): 91.3 ± 10.5 kg) performed maximal CMJ under 5 experimental conditions in a randomised, counterbalanced order: unloaded, and with additional loads of 25%, 50%, 75%, and 100% of BM. Peak power and average power were maximised during the unloaded condition, both decreasing significantly (P < 0.05) as load increased. Net impulse was maximised with 75% of BM, which was significantly greater (P < 0.05) than the unloaded and 100% of BM conditions. Net mean force and mean velocity were maximised during the unloaded condition and decreased significantly (P < 0.05) as load increased, whereas phase duration increased significantly (P < 0.05) as load increased. As such, the interaction between barbell load and the underpinning force, time, and displacement components should be considered by strength and conditioning coaches when prescribing barbell loads.  相似文献   

Characteristics and experiences of interns in strength and conditioning     

Paul Read  Jonathan D. Hughes  Richard Blagrove  Ian Jeffreys  Mike Edwards  Anthony N. Turner 《Journal of sports sciences》2017,35(3):269-276

Student coaches undertake internships to develop practical skills and gain experience to improve employability prospects. The characteristics of the coaches who undertake these internships, their experiences and the nature of the work being performed are currently unknown. The purpose of this study was to report the characteristics of strength and conditioning (S&C) coaches who have undertaken internships and their experiences during their respective placements. A total of 113 men and 6 women completed an online survey. Placements generally lasted 6–12 months (66%), were unpaid (93%) and took place at professional teams (63%). All respondents had a standard of experience prior to commencement (82%); a higher-education degree (bachelor’s degree 56%; master’s degree 18%) and others were qualified S&C coaches (16%). Activities consisted largely of coaching (47%), data collection (22%) and equipment set-up (25%) but lacked provision of appropriate training. Mentors were allocated to interns; however, often developmental objectives were not discussed, meetings were rarely documented, and in some cases, no meetings took place. This study suggests that internships offer worthwhile experiences and assistance in skill development to progress in S&C. However, clearer guidelines are required to define the responsibilities of employers and interns, to maximise these experiential learning opportunities and avoid the exploitation of willing students.  相似文献
