Observational data collected prior to the pandemic (between 2004 and 2019) were used to simulate the potential consequences of early childhood care and education (ECCE) service closures on the estimated 167 million preprimary-age children in 196 countries who lost ECCE access between March 2020 and February 2021. COVID-19-related ECCE disruptions were estimated to result in 19.01 billion person-days of ECCE instruction lost, 10.75 million additional children falling “off track” in their early development, 14.18 million grades of learning lost by adolescence, and a present discounted value of USD 308.02 billion of earnings lost in adulthood. Further burdens associated with ongoing closures were also forecasted. Projected developmental and learning losses were concentrated in low- and lower middle-income countries, likely exacerbating long-standing global inequities.  相似文献

Alliances are not enough explaining rapid growth in biotechnology firms     

Jorge Niosi 《Research Policy》2003,32(5):737-750

The goal of this paper is to understand the factors explaining differential growth in biotechnology firms. It aims also to add some caution to the generalized opinion according to which alliances are the key factor behind new firm performance. The theoretical framework is based on competence, and evolutionary theories of the firm. These approaches underline the fact that within similar industries and technologies firms display clear and persistent variety in performance. Some 60 dedicated biotechnology firms (DBFs) were interviewed across Canada; half of them experienced rapid growth. A few variables, including alliances, explained much of the fast growth.  相似文献   

Paraprofessionals use of group school-based instrumental mentoring: Examining process and preliminary outcomes     

Gerald G. Strait  Jenna Turner  Diana Stinson  Samanthia Harrison  Rojan Bagheri  Tanya Perez  Bradley H. Smith  Jorge Gonzalez  Jacqueline R. Anderson  Jill Simpson  Sam D. McQuillin 《Psychology in the schools》2020,57(9):1492-1505

Many schools use paraprofessionals to implement and monitor interventions. Though paraprofessionals are cost-effective, many questions remain about the training and skills they need to implement a wide array of school-based interventions. In this study, we compare paraprofessionals' (i.e., undergraduates) implementation of the Group-Academic Mentoring Program for Education Development (Group-AMPED) to school psychology graduate students' implementation of Group-AMPED. Ten paraprofessionals and five school psychology graduate students provided approximately eight sessions of Group-AMPED to 35 sixth-grade students. Results indicated no significant differences between middle school students' engagement when groups were led by either school psychology graduate students or paraprofessionals. Similarly, self-reports of fidelity and supervisor postsession implementation confidence indicated no difference between paraprofessionals and graduate students' implementation of Group-AMPED. Follow-up measures indicated that mentors and proteges perceived Group-AMPED as feasible, acceptable, and understandable. Most importantly, middle school students participating in Group-AMPED had significantly higher second-semester grades in comparison to a small control group.  相似文献

Towards the use of multidimensional performance indicators in football small-sided games: the effects of pitch orientation     

Hugo Folgado  Jorge Bravo  Paulo Pereira  Jaime Sampaio 《Journal of sports sciences》2019,37(9):1064-1071

This study aimed to compare youth football players’ performance during two small-sided games with different pitch orientation: i) 40x30m and ii) 30x40m formats. Twenty under-15 players (age = 14.1 ± 0.5 years) participated in nine GK+4vs4+GK situations in each format, with the duration of six minutes each. Positional data were collected using individual GPS units, and computed for tactical and physical performance indicators. The SSG were video recorded, using notational analysis for collecting technical indicators. A novel method that incorporates time dependent notational information with spatiotemporal data was used to compute multidimensional parameters. Standardised effect sizes and non-clinical magnitude-based inferences were used to compare formats. Results showed that players covered more distance at higher intensities, presented more passes and dribbles and were more synchronised in the longitudinal axis while playing in the 40x30m pitch. In the 30x40m pitch, results showed a lower distance between team centroids, higher number of shots, more lateral passes and a wider team positioning. Multidimensional indicators, as players position and distance to the closest defender while shooting, revealed a more constant distance between attacker and defender in the 40x30m pitch. These results highlight the importance of integrating information from different indicators for a contextually valid information.  相似文献   

Start and turn performances of elite sprinters at the 2016 European Championships in swimming     

Jorge E. Morais  Daniel A. Marinho  Raul Arellano  Tiago M. Barbosa 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(1):100-114

The aim of this study was to examine the performance characteristics of male and female finalists in the 100-m distance at the 2016 European Championships in swimming (long-course-metre). The performances of all 64 (32-males and 32-females) were analysed (8 swimmers per event; Freestyle, Backstroke, Breaststroke and Butterfly). A set of start and turn parameters were analysed. In the start main outcome, male swimmers were faster in Butterfly (5.71 ± 0.14s) and females in Freestyle (6.68 ± 0.28s). In the turn main outcome, male and female swimmers were faster in Freestyle (males: 9.55 ± 0.13s; females: 10.78 ± 0.28s). A significant and strong stroke effect was noted in the start and turn main outcome, in both sexes. In the start plus the turn combined, males and females were faster in Freestyle (males: 15.40 ± 0.20s; females: 17.45 ± 0.54s). The start and the turn combined accounted almost one-third of the total race time in all events, and non-significant differences (p > 0.05) were noted across the four swim strokes. Once this research made evident the high relevance of start and turns, it is suggested that coaches and swimmers should dedicate an expressive portion of the training perfecting these actions.  相似文献   

Motor fitness and preschooler children obesity status     

Sandra Silva-Santos  Amanda Santos  Susana Vale  Jorge Mota 《Journal of sports sciences》2017,35(17):1704-1708

The aim of this study was to examine the association between motor fitness (MF) and obesity status in preschool children.

The sample comprised 467 children aged 3–6 years. Preschool children body mass index was classi?ed according to International Obesity Task Force and categorised into three levels, normal, overweight and obesity. Total physical activity was assessed by accelerometer and MF test was assessed through two MF tests 10 × 5m shuttle run test (SRT) and a 7 m jumping distance on 2 feet test (J2F). Low MF was considered for MF if SD above 1. A single variable with three categories was created: low MF medium MF and high MF.

The prevalence of normal weight, overweight and obesity was 67.6%, 22.7% and 9.7%, respectively. The prevalence of SD > 1 for SRT was 13.7% and 14.4% for J2F, for single variable was 19.2%. Multinomial logistic regression analysis showed that obese preschoolers were more likely six times classified as having low MF level than their non-overweight counterparts (OR: 6.4; IC: 1.3–36.6).

This study showed a considerable prevalence of overweight and obesity among preschoolers. Obesity has already been associated with lower MF. Further longitudinal studies are needed to con?rm this data.  相似文献
