Capoeira for beginners: self-benefit for,and community action by,new Capoeiristas

Capoeira could be defined as a Brazilian martial art and game to be played. This research explored how capoeira play might be considered to facilitate connectedness amongst newly-recruited persons, plus any other ramifications of capoeira involvement. A beginners’ course of capoeira was provided to participants, free of charge, in an English city in the West Midlands—new capoeiristas in a new venue for capoeira. Researchers attended classes to collect/construct overt non-participant observation data. In addition, semi-structured interviews were undertaken with the new capoeiristas post-course. This article explores researchers’ observation fieldnotes and interviewees’ narratives. These qualitative data-driven debates include the concepts: self, identity, escapism, multiparty endeavour, community, temporality, enjoyment, and transcending boundaries. Capoeira is theorised in a fresh manner that highlights social benefits of capoeira—for example as an enjoyable and supportive group endeavour which includes elements of social play and community-building—plus benefits for self that can transcend the boundaries of the class. Findings highlight how capoeira can be considered an inherently multiparty endeavour whereby social actors form, and experience, a community in order to embrace capoeira play. Data suggest capoeira can facilitate group playfulness, joviality, and laughter. Further, capoeiristas can enact and experience—some mode of—escapism via capoeira, whereby new place and pursuit can facilitate hedonistic diversion from the mundane. Capoeira appears to provide adventure and liberation into a relatively unburdened part of, or place in, social life. Corporeal and discursive boundary-empowerment can also be experienced by capoeiristas, fostering positive identity work in the wider world. Capoeira can be argued to facilitate mutuality (e.g. community experience and group work) and egoism (e.g. an individual's identity work) concurrently. This research suggests that modified capoeira for beginners can be beneficial for both the new capoeiristas themselves and for positive community action during and beyond class.     

An experimental,video-based investigation into the motivating impact of choice and positive feedback among students with different motor competence levels

ABSTRACT

Background: Research stemming from Self-Determination Theory (SDT) shows that physical education (PE) teachers who endorse an autonomy-supportive and structuring motivating style positively affect students’ motivation, engagement and learning. Choice provision and positive feedback are two concrete strategies that are part of an autonomy-supportive and structuring style, respectively. While the benefits of choice provision and positive feedback have been shown in contexts other than PE, evidence in the specific context of PE is much scarcer. Grounded in SDT and relying on experimental design, the present study sought to examine the effects of choice provision and positive feedback on students’ motivational experiences in PE, and whether these effects were moderated by students’ actual motor competence (AMC).

Method: A sample of 277 students (41% boys, Mage?=?12.78 years) was randomly assigned to one of four experimental conditions (2?×?2 design). Prior to the experimental manipulation, participants’ AMC was measured with the Test of Gross Motor Development second edition. Participants then watched a videotaped PE lesson, in which the provision of choice (choice – no choice) and type of feedback (corrective feedback – positive and corrective feedback) were manipulated. Participants were asked to imagine how they would feel being a student in the displayed lessons. After watching the video, they completed validated questionnaires on their (1) anticipated need satisfaction and frustration and (2) autonomous and controlled motivation. MANOVAs were conducted to investigate the differences between the experimental groups in terms of anticipated need satisfaction, need frustration and motivation. Multiple linear regression analyses were used to examine the potential moderating role of AMC.

Findings and conclusions: The benefits of choice provision were clearly shown with students in the choice condition anticipating significantly more autonomy, competence and relatedness satisfaction and autonomous motivation, while they anticipated significantly less autonomy and relatedness frustration when compared to students in the no choice condition. Similarly, the addition of positive feedback to corrective feedback yielded clear benefits, with lower averages in anticipated need frustration found among students who watched the videos in which positive feedback was added to corrective feedback. No support was provided for a synergetic motivational effect between choice and positive feedback. Overall, the present findings show the importance of offering choice and providing positive feedback to motivate students in PE, with positive effects being present for all students independent of their initial AMC levels. Although few interaction effects were found, lowly motor competent students benefited even more from receiving positive feedback than highly motor competent students. The findings of this study are important to take into account in PE teacher education programs and professional training programs for PE teachers about how to teach in a (more) motivating way.     

Did the European Migrant Crisis Change News Coverage of Immigration? A Longitudinal Analysis of Immigration Television News and the Actors Speaking in It

Although immigration always has been an issue of political debate, the 2015 European migrant crisis led to an enormous increase in attention from policymakers and news media. Many studies already focused on the representation of the crisis in the news, but no systematic longitudinal research existed comparing coverage in crisis and non-crisis times. This study analyzes all television news items on immigration in Flanders (Belgium) from the two main broadcasters from the period 2003–2017. By doing so, we are able to study whether there are changes in immigration coverage before and during the crisis years. We focus specifically on the actors that get the opportunity to voice their point of view on immigration and on the issues related to immigration. Our results show that before the crisis, immigration news coverage on the commercial and public service broadcaster was relatively similar. However, during the crisis their approach changes. The commercial broadcaster criminalizes immigration more and focuses on political actors. The public broadcaster opts for a broader issue approach and gives the word more to citizens and immigrants during the crisis. We elaborate in the conclusion on how crises can change the nature of reporting.

Fostering students’ creativity via educational robotics: An investigation of teachers’ pedagogical practices based on teacher interviews

This study explored how educational robotics (ER) was implemented in classrooms to foster creativity among elementary school students and identified challenges associated with its implementation. Twenty-six teachers at different elementary schools were interviewed. In-depth teacher interviews and grounded theory were used to collect and analyze the interviews. We found that the intended creative learning outcome for students was mastery of the developmental process of creativity. The teachers generally reported using a four-phase instructional framework consisting of eight sub-phases and targeted teaching strategies to support students’ learning outcomes. Challenges included insufficient appropriate learning materials, a lack of expansive learning activities and tasks and limited opportunities to engage students in the process of design thinking and developing metacognitive abilities. The findings have practical implications for teachers and researchers who are interested in developing pedagogical practices (PP) incorporating ER to support students’ creativity. The study also has theoretical value, offering insights into teachers’ PP in implementing ER.     

Query-oriented text summarization based on hypergraph transversals

The rise in the amount of textual resources available on the Internet has created the need for tools of automatic document summarization. The main challenges of query-oriented extractive summarization are (1) to identify the topics of the documents and (2) to recover query-relevant sentences of the documents that together cover these topics. Existing graph- or hypergraph-based summarizers use graph-based ranking algorithms to produce individual scores of relevance for the sentences. Hence, these systems fail to measure the topics jointly covered by the sentences forming the summary, which tends to produce redundant summaries. To address the issue of selecting non-redundant sentences jointly covering the main query-relevant topics of a corpus, we propose a new method using the powerful theory of hypergraph transversals. First, we introduce a new topic model based on the semantic clustering of terms in order to discover the topics present in a corpus. Second, these topics are modeled as the hyperedges of a hypergraph in which the nodes are the sentences. A summary is then produced by generating a transversal of nodes in the hypergraph. Algorithms based on the theory of submodular functions are proposed to generate the transversals and to build the summaries. The proposed summarizer outperforms existing graph- or hypergraph-based summarizers by at least 6% of ROUGE-SU4 F-measure on DUC 2007 dataset. It is moreover cheaper than existing hypergraph-based summarizers in terms of computational time complexity.     

Electroencephalogram and Heart Rate Regulation to Familiar and Unfamiliar People in Children With Autism Spectrum Disorders

Few studies have examined whether familiarity of partner affects social responses in children with autism. This study investigated heart rate regulation (respiratory sinus arrhythmia [RSA]: The myelinated vagus nerve's regulation of heart rate) and temporal–parietal electroencephalogram (EEG) activity while nineteen 8- to 12-year-old children with autism and 14 controls viewed videos of a familiar and an unfamiliar person reading a story. Children with autism had lower overall RSA levels and exhibited decreased RSA to the unfamiliar person, versus control children. Both groups decreased temporal–parietal EEG activity to the unfamiliar person. Higher RSA was related to higher social skill ratings and fewer problem behaviors. Thus, the social difficulties of children with autism may be characterized by specific mobilization to unfamiliar people.     

Associations Between Father Absence and Age of First Sexual Intercourse

Children raised without a biological father in the household have earlier average ages of first sexual intercourse than children raised in father-present households. Competing theoretical perspectives have attributed this either to effects of father absence on socialization and physical maturation or to nonrandom selection of children predisposed for early sexual intercourse into father-absent households. Genetically informative analyses of the children of sister dyads ( N  = 1,382, aged 14–21 years) support the selection hypothesis: This association seems attributable to confounded risks, most likely genetic in origin, which correlated both with likelihood of father absence and early sexual behavior. This holds implications for environmental theories of maturation and suggests that previous research may have inadvertently overestimated the role of family structure in reproductive maturation.
