Effects of personal and professional factors on teachers’ attitudes towards inclusion in preschool

Attitudes towards inclusive education have a crucial place in the effective implementation of inclusion practices. The aim of this study was to explore teachers’ attitudes towards inclusive education in preschool education in Portugal and to identify teachers’ personal and professional variables that influence these attitudes. The data were collected from a sample composed of 68 preschool teachers working in mainstream schools located in urban and rural areas. The results indicated overall positive attitudes towards inclusion. Having previous personal contact with a person with special educational needs predicted more positive affective attitudes, whereas having previous experience teaching classes that included students with and without special educational needs predicted less positive behavioural intentions. From these results, we infer an emergent need for continuous training and for the promotion of positive attitudes among preschool teachers to achieve the successful implementation of inclusion at this educational level.     

Brazil Meets the Global Challenge: IT Policy in a Postliberalization Environment

Since the early 1990s, Brazilian IT policy has changed substantially from greenhouse protectionism in selected segments of the market to a more liberal regime. This article analyses the impact of liberalization on IT equipment production, diffusion, employment, and foreign trade. There were both benefits and setbacks, depending on the aspect analyzed. Users benefited from greater access to imported equipment, which could eventually contribute to productivity growth in the overall economy.On the negative side, there was a loss of local linkages with internal sources of components, technology, and employment. The article concludes that the future of the Brazilian IT industry does not seem to be in commodity hardware production. Rather, it lies in design- and engineering-intensive applications. Such "production close to use" can spur domestic use as well as create business opportunities for domestically owned companies in markets not dominated by foreign multinationals.     

A New Inventory for Assessing Affordances in the Home Environment for Motor Development (AHEMD-SR)

A contemporary view of motor development considers environmental influences as critical factors in optimal growth and behavior, with the home being the primary agent. The intent of this communication is to introduce the Affordances in the Home Environment for Motor Development Self-Report (AHEMD-SR) to early childhood practitioners. The AHEMD-SR is a reliable and valid parental self-report assessment instrument that addresses the quality and quantity of factors (affordances and events) in the home that are conducive to enhancing motor development in children ages 18–42 months. The instrument could provide useful information in a wide variety of settings, including applications to intervention and remediation.     

Thinking with your fingers and touching with your mind: the cognitive dance of Edith Ackermann / Pensando con los dedos y tocando con la mente: la danza cognitiva de Edith Ackermann

Edith Ackermann was one of the most important scholars in the interdisciplinary field of Child-Computer Interaction. Trained as a developmental psychologist and having worked with Jean Piaget in Switzerland, Ackermann went to MIT in 1985 to join an intrepid group of researchers led by Seymour Papert who were trying to understand how extant theories of development and learning would fare in a world in which children would be surrounded by computational artefacts. For the ensuing three decades, Ackermann would use her unique interdisciplinary expertise in the service of creating new theories of development for this new world, generating cutting-edge research, inspiring a generation of students, and producing seminal papers. This article, making use of literature as well as interviews with colleagues of Edith, discusses Ackermann’s contribution to the field, her life trajectory, impact, and ideas. Edith passed away on 24 December 2016.     

Should students design or interact with models? Using the Bifocal Modelling Framework to investigate model construction in high school science

The Bifocal Modelling Framework (BMF) is an approach for science learning which links students’ physical experimentation with computer modelling in real time, focusing on the comparison of the two media. In this paper, we explore how a Bifocal Modelling implementation supported learning outcomes related to both content and metamodeling knowledge, focusing on the role of designing models. Our study consisted of three conditions implemented with a total of 69 9th grade high-school students. The first and second classes were assigned two implementation modes of BMF: with and without a model design module. The third condition, employed as a control, consisted of a class that received instruction in the school’s traditional approach. Our results indicate that students participating in both BMF implementations demonstrated improved content knowledge and a better understanding of metamodeling. However, only the ‘BMF-with-design’ group improved significantly in both content and metamodeling knowledge. Our qualitative analyses indicate that both BMF groups designed detailed models that included scientific explanations. However only students who engaged in the model design component: (1) completed a detailed model displaying molecular interaction; and (2) developed a critical perspective about models. We discuss the implications of those results for teaching scientific science concepts and metamodeling knowledge.     

The AGTR2 rs11091046 (A>C) polymorphism and power athletic status in top-level Brazilian athletes

The main purpose of this study was to investigate if the rs11091046 (A>C) polymorphism in AGTR2 gene is associated with athletic status in top-level athletes from Brazil. Since the AGTR2 gene is located on the X chromosome, the case-control association study was done separately for women and men. The female cohort was composed of 205 athletes and 241 non-athletes, and the male cohort was composed of 419 athletes and 490 non-athletes. We did not identify an association between the C-allele and the endurance phenotype. However, power athletes had a higher frequency of the A-allele. In women, A/A genotype was overrepresented in international-level power group compared with non-athletes or international-level endurance athletes (23.2% vs. 16.6% or 8.8%, respectively; p < 0.05). In men, the A-allele frequency observed in power athletes or international-level power athletes was statistically different from that observed in non-athletes (51.6% or 57.8% vs. 40.4%; p < 0.009). Furthermore, men sprinters with the A-allele showed significantly faster personal best times for the 100 m than those with the C-allele (10.56 ± 0.32 s vs. 10.93 ± 0.49 s; p < 0.02). In conclusion, it was found that the AGTR2 A-allele is a candidate genetic marker for top-level power athletes.     

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

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.     

The Effect of In-Season Traditional and Explosive Resistance Training Programs on Strength,Jump Height,and Speed in Recreational Soccer Players

Purpose: Resistance training is often performed in a traditional training style using deliberate relatively longer repetition durations or in an explosive training style using maximal intended velocities and relatively shorter repetition durations. Both improve strength, “power” (impulsivity), and speed. This study compared explosive and traditional training over a 6-week intervention in 30 healthy young adult male recreational soccer players. Method: Full body supervised resistance training was performed 2 times a week using 3 sets of each exercise at 80% of one repetition maximum to momentary failure. Outcomes were Smith machine squat 1 repetition maximum, 10 meter sprint time, and countermovement jump. Results: Both groups significantly improved all outcomes based on 95% confidence intervals not crossing zero. There were no between-group differences for squat 1 RM (TRAD = 6.3[5.1 to 7.6] kg, EXP = 5.2[3.9 to 6.4] kg) or 10 meter sprint (TRAD = ?0.05[?0.07 to ?0.04] s, EXP = ?0.05[?0.06 to ?0.03] s). Explosive group had a significantly greater increase in countermovement jump compared to the traditional group (TRAD = 0.7[0.3 to 1.1] cm, EXP = 1.3[0.9 to 1.7] cm). Conclusion: Both the traditional training and explosive training performed to momentary failure produced significant improvements in strength, speed, and jump performance. Strength gains are similar independent of intended movement speed. However, speed and jump performance changes are marginal with resistance training.     

高水平青年男子足球运动员赛前热身活动

采用可穿戴电子设备,对2019赛季“全国青少年男子足球超级联赛”19岁以下年龄组的一支参赛球队的24名青年运动员参加的8场正式比赛的赛前热身活动和比赛负荷进行量化分析。结果显示：（1）该运动队的赛前热身时间平均为（27.8±4.6） min,首发球员和替补球员在赛前热身活动中的各项负荷量化指标皆体现出极其显著的中等至非常大程度差异（P＜0.001,ES值介于0.72和3.17）;（2）首发且打满全场的运动员赛前热身活动的跑动总距离占比赛跑动总距离的18.6%±3.2%,加速度负荷总量占24.5%±4.1%,首发打满全场、首发被换下、替补45 min以上和替补未满45 min四组不同出场时间的运动员的赛前热身活动的各项负荷指标占比赛负荷指标的比重皆体现出显著性差异（P＜0.013,ηp2介于0.10和0.44）。研究认为,赛前热身活动的负荷量应该被计入比赛日的负荷总量,用于足球运动员的训练负荷管理与训练任务设计参照,且不同出场时间带来的负荷差异应该被纳入考量范围。
