Developmental dyslexia in an orthography of intermediate depth: the case of European Portuguese

Fifteen Portuguese children with dyslexia, aged 9–11 years, were compared with reading and chronological age controls with respect to five indicators related to the phonological deficit hypothesis: the effects of lexicality, regularity, and length, implicit and explicit phonological awareness, and rapid naming. The comparison between groups indicates that Portuguese children with dyslexia have a phonological impairment which is revealed by a developmental deficit in implicit phonological awareness and irregular word reading (where younger reading level controls performed better than dyslexics) and by a developmental delay in decoding ability and explicit phonological awareness (where dyslexics matched reading level controls). These results are discussed in relation to the idea that European Portuguese is written in an orthography of intermediate depth.     

Key determinants of time to 5 m in different ventral swimming start techniques

The aim of this study was to determine the biomechanical parameters that explain ventral start performance in swimming. For this purpose, 13 elite swimmers performed different variants of the ventral start technique. Two-dimensional video analyses of the aerial and underwater phases were used to assess 16 kinematic parameters from the starting signal to 5?m, and an instrumented starting block was used to assess kinetic data. A Lasso regression was used to reduce the number of parameters, providing the main determinants to starting performance, revealing different combinations of key determinants, depending on the variant (r²?≥?0.90), with flight distance being the most relevant to all variants (r?≤??0.80; p?r?=??0.79; p?r?≤?0.61; p?r²?=?0.66) or block time and flight distance (r²?=?0.83). These data provide relevant contributions to the further understanding of the biomechanics of swimming starts as well as insights for performance analysis and targeted interventions to improve athlete performance.     

Have the poor found their own appropriate

Correspondence schools in Brazil are entirely in the hands of private entrepreneurs and ignored, even despised, by official educators. Yet, as this paper shows, they can, —in many cases, do—, provide helpful education for those who have no other access to educational opportunity. Indeed, they appear to offer the most equal form of opportunity. Accompanying their benefits, however, are many imperfections and abuses. The paper identifies five areas where government intervention could help both the public and the correspondence schools, without stifling their current vitality.     

Discrimination blocking: Acquisition versus performance deficits in human contingency learning

We compared acquisition and performance accounts of human contingency learning. After solving a discrimination in Phase 1, in which Cue A predicted the occurrence of the outcome and Cue B predicted its nonoccurrence (A+/B−), a new discrimination (X+/Y−) was superimposed in Phase 2 (AX+/BY−). The participants were finally trained in Phase 3 with the added discrimination, which either maintained the same contingencies as those in Phase 2 (X+/Y−; Experiment 1) or reversed the contingencies (X−/Y+; Experiment 2). According to competitive-learning theories (e.g., Rescorla & Wagner, 1972), there should be no learning of the added discrimination in Phase 2, so that no advantage or disadvantage for this discrimination should be observed in Phase 3. In contrast, performance theories, such as the comparator hypothesis (Miller & Matzel, 1988), contend that learning of the added discrimination in Phase 2 should proceed normally; so, in Phase 3, an advantage for the added discrimination should be observed in Experiment 1, but a disadvantage should be observed in Experiment 2. Our participants learned about the added discrimination and generally showed the effects predicted by the comparator hypothesis.

Resilience strategies for new teachers in high-needs areas

This qualitative study investigates strategies of resilience exhibited by fifteen novice teachers employed in high-needs areas, such as in urban and rural contexts and in special education. Findings indicated that teachers utilised a variety of strategies, including help-seeking, problem-solving, managing difficult relationships, and seeking rejuvenation/renewal. These strategies assisted beginning teachers in building additional resources and support; however, the burden for success and securing resources fell on teachers themselves. Furthermore, the researchers recognised that resilient teachers demonstrated agency in the process of overcoming adversity. Implications for future practice and research are discussed.     

Understanding parental views of adolescent sexuality and sex education in Ecuador: a qualitative study

Parents' contribution to sex education is increasingly receiving research attention. This growing interest stems from recognition of the influence that parental attitudes may have both on young people's sexual attitudes and behaviour, and on school-based sex education. Studies regarding parental attitudes towards sexuality are, however, still rare. The two main objectives of this study were to explore parental views about sexuality and to understand parental attitudes towards sex education. Four focus group discussions were conducted with parents from high schools in Cuenca, Ecuador. Data were analysed using thematic analysis. The study revealed that parents held a restricted view about sex education, grounded in traditional religious ideas about sexuality, which led parents to understand it as a morally and physically dangerous activity. Although parents expressed a willingness to make good quality sex education available to their children, they reported having insufficient personal resources to fulfil that objective. The results of this study provide important information about the need to develop and adapt sex education to each specific cultural context, thereby confirming the importance of knowing about the cultural traditions and religious beliefs that may form obstacles to effective sex education for young people in Ecuador.     

Early development among dual language learners: The roles of language use at home,maternal immigration,country of origin,and socio-demographic variables

Using nationally representative data from the ECLS-B, we examined children's outcomes and growth from 9 to 65 months as a function of language used in the home at 24 months (English only n = 7300; English and another language n = 1500; other language only n = 400). We also examined whether demographic variables moderated the effects of DLL status in predicting child outcomes. Results revealed substantial variation within the DLL population within and across language groups in immigration status, heritage country, child outcomes, and family socioeconomic risk. DLL status was associated with differential outcomes, gains over time, and processes in complex ways. Maternal birth outside of the U.S., child gender, and parental education moderated relations between home language and child outcomes. Use of the heritage language at home served as a protective factor for children of immigrant families for a few outcomes. Gender and parental education were more strongly associated with child outcomes among English-speaking households than among DLLs.
