As the number of young dual language learners (DLLs) in early care and education (ECE) programs is increasing, it is critical to examine how well measures of the quality of practices in these settings reflect the needs of the diverse groups of children being served. This review of the research literature addressed these questions for ECE settings serving children birth-five: whether quality differs for settings serving high proportions of DLLs compared to typical samples, whether existing quality measures exhibit similar psychometric characteristics and associations with child outcomes in settings serving DLL and non-DLL children, and whether DLL-specific measures perform differently than general measures of quality. The search procedure produced 10 research studies that met the criteria for inclusion in the review out of approximately 3800 that were found initially and more than 300 that were reviewed. These studies included 10 out of 46 identified measures of ECE quality, including both general and DLL-specific measures. Findings suggested that widely used general ECE quality measures function similarly for DLLs compared to typical populations with regard to overall quality, psychometric characteristics, and child outcomes. Further research is needed to broaden the knowledge base for a wider variety of measures, beyond center-based settings, and beyond Spanish-speaking DLLs, as well as to enhance methodological approaches. There appear to be potential research opportunities through numerous existing studies that included DLL populations but had not analyzed their data in regard to these groups.  相似文献

This content analysis of 15 Arabic and 3 Turkish drama serials on transnational Arab television examined the gender portrayals of characters. The analysis of 743 characters found that women were underrepresented, less likely to have recognizable jobs, and more likely than men to be portrayed in sex-typed occupations, activities, and settings. The analysis also revealed that programs with female writers were significantly less gender stereotypical. Moreover, differences were found among the producing Arab countries in terms of the portrayals of women; conservative countries had more sex-typed portrayals than the more liberal Arab countries, whereas Turkish programs had similar portrayals to Arabic programs produced in the liberal Arab states. The general findings are discussed in comparison to U.S. programming, and in relation to selective exposure, identification with characters, and potential effects on Arab viewers' gender role beliefs.  相似文献

ABSTRACT

A research project was undertaken by a university library system to develop a sustainable user experience strategy. A task force was convened to conduct a pilot project with members from both libraries in the system to assess staffing responsibilities, guidelines, processes, and data-gathering procedures. The team tested an electronic resources list common to both libraries. In describing the methods employed by the task force in their research, this article outlines the benefits and drawbacks of staffing configurations to initiate user experience practices in an academic library setting.  相似文献

In 2004, Chicago Children's Museum founded the Play For All initiative, which creates a community where play and learning connect for visitors of all abilities. The Play For All team discovered that families with children with disabilities were looking for an opportunity to explore and enjoy the museum without limitations and the fear of being judged. CCM also learned that being ADA compliant was not enough; being accessible and inclusive meant going above and beyond the ADA. Children's museums are a rare treat where almost everything should be interactive and ready to be played with. The Play For All team has made significant changes to the exhibits, staff training, and programming at Chicago Children's Museum by working with local families with disabilities and partner organizations. A culture shift has taken place within CCM. Play For All is now a top priority when decisions are being made.  相似文献

This study examined the potential of entertainment-education (E-E) for promoting engagement with a science issue. It was assumed that certain entertaining features of a media experience increase viewers’ perceived knowledge about an issue. Drawing on different theoretical models of E-E and on persuasive effects of narrative media messages, three hypotheses and one research question were assessed in a survey among 103 participants, who were shown a movie about genetic engineering beforehand. Results suggested that the higher viewers’ transportation, identification, and enjoyment were, the more they actually felt informed. Viewers’ degree of transportation, though, revealed to be sufficient to explain their perceived knowledge.  相似文献

The purpose of this study was to estimate the optimal body size, limb-segment length, girth or breadth ratios for 100-m backstroke mean speed performance in young swimmers. Sixty-three young swimmers (boys [n = 30; age: 13.98 ± 0.58 years]; girls [n = 33; age: 13.02 ± 1.20 years]) participated in this study. To identify the optimal body size and body composition components associated with 100-m backstroke speed performance, we adopted a multiplicative allometric log-linear regression model, which was refined using backward elimination. The multiplicative allometric model exploring the association between 100-m backstroke mean speed performance and the different somatic measurements estimated that biological age, sitting height, leg length for the lower-limbs, and two girths (forearm and arm relaxed girth) are the key predictors. Stature and body mass did not contribute to the model, suggesting that the advantage of longer levers was limb-specific rather than a general whole-body advantage. In fact, it is only by adopting multiplicative allometric models that the abovementioned ratios could have been derived. These findings highlighted the importance of considering somatic characteristics of young backstroke swimmers and can help swimming coaches to classify their swimmers and enable them to suggest what might be the swimmers’ most appropriate stroke (talent identification).  相似文献

The purpose of this study was to compare the validity and reliability of three short physical activity self-report instruments to determine their potential for use with university student populations. The participants (N = 155; 44.5% male; 22.9 ± 5.13 years) wore an accelerometer for 9 consecutive days and completed a single-item measure, the a brief two item measure and the International Physical Activity Questionnaire—Short Form questionnaires on day 1 and 9. Correlations between self-reported and accelerometer derived moderate-to-vigorous physical activity levels were moderate for the International Physical Activity Questionnaire—Short Form, while poor for the single-item measure and the a brief two item measure. The agreement level was high with the International Physical Activity Questionnaire—Short Form (77.4%) and moderate for both the single-item measure (45.2 %) and a brief two item measure (44.5 %). The intraclass correlations between the two administrations were moderate to strong across all measures (0.52–0.70) in 133 participants. The International Physical Activity Questionnaire—Short Form is the most suitable of these three self-report instruments for use with this population due to higher correlations and levels of agreement with accelerometry.  相似文献

The displacement of the golf ball struck by a driving club is affected by several player characteristics and equipment parameters and their interrelationships. Some modelling and simulation studies have shown a relationship between shaft length and clubhead speed, supported by a few experimental studies. The aim of the present study was to examine the relationship between driver length and ball launch conditions in an indoor test facility using a ball launch monitor. Nine males considered to be skilled golfers participated in the study. Four driving clubs of total length 117, 119, 124, and 132 cm were assembled from commercially available components and were used to strike golf shots while initial ball velocity, backspin rate, and launch angles were measured. Statistical analysis identified a significant difference in initial launch speed due to club length, a significant difference between participants, but no difference between the trials for a given golfer. A positive trend was noted between backspin and launch angle for all four clubs, and significant inverse associations between initial launch speed and backspin rate and launch angle. However, the combined launch conditions associated with increasing length were not considered optimal, with uncontrolled swingweight and moment of inertia effects considered to be limiting factors.  相似文献

Acute whole body vibration training (WBVT) is a tool used amongst coaches to improve performance prior to activity. Its effects on other fitness components, such as balance and stability, along with how different populations respond are less well understood. The aim of the current research is to determine the effect of acute WBVT on balance and stability amongst elite and amateur soccer players. Forty-four healthy male soccer players (22 elite and 22 amateur) were assigned to a treatment or control group. The intervention group then performed 3 × 60 seconds static squat on vibration platform at 40 Hz (±4 mm) with Y balance test (YBT) scores and dynamic postural stability index (DPSI) measured pre and post. DPSI was significantly lower in the elite players in the acute WBVT compared to amateur players (F1, 40= 6.80; P = 0.013). YBT anterior reach distance showed a significant improvement in both amateur and elite players in the acute WBVT group (F1, 40= 32.36; P < 0.001). The improvement in DPSI amongst the elite players indicates a difference in responses to acute high frequency vibration between elite and amateur players during a landing stability task. The results indicate that acute WBVT improves anterior YBT reach distances through a possible improvement in flexibility amongst both elite and amateur players. In conclusion, acute WBVT training appears to improve stability amongst elite soccer players in comparison to amateur players, the exact reasoning behind this difference requires further investigation.  相似文献
