Known risk factors for violence predict 12-month-old infants' aggressiveness with peers

This study tested the hypothesis that 12-month-old infants' use of force against peers is associated with known risk factors for violence. We conducted a prospective longitudinal study, which included laboratory observations of firstborn British infants (N = 271) during simulated birthday parties. No gender differences in aggressiveness were observed. The infants' observed aggressiveness was significantly correlated with mothers' mood disorder during pregnancy and with mothers' history of conduct problems. Infants' observed aggressiveness was correlated with parents' ratings of infants' anger and aggression, which were also predicted by mothers' mood disorder and history of conduct problems. Our findings indicate that infants at risk for serious aggression can already be identified when the motor ability to use physical force first enters the human repertoire.

Thinking about the past, present and future in adolescents growing up in Children's Homes

The present study tested the hypothesis that adolescents growing up in Children's Homes differ from adolescents growing up in a family environment in how they think about their past, present and future, in the way they make decisions about future events and rewards, and in their levels of empathy and perspective taking. The participants were 40 adolescents from Children's Homes in Budapest, Hungary, and 40 age- and gender-matched controls. Group differences were found in participants' past and present time perspectives, and girls from Children's Homes showed reduced consistency in their plans for the future. Additionally, gender differences emerged in empathy, perspective taking, and in participants' present and future time perspectives. We discuss the implications of our findings for interventions to improve the future prospects of adolescents in Children's Homes.

Boys' underachievement, educational aspirations and constructions of locality

Over recent years the moral panic that has surrounded 'boys' underachievement' has tended to encourage crude and essentialist comparisons between all boys and all girls and to eclipse the continuing and more profound effects on educational achievement exerted by social class and 'race'/ethnicity. While there are differences in educational achievement between working class boys and girls, these differences are relatively minor when comparing the overall achievement levels of working class children with those from higher, professional social class backgrounds. This paper argues that a need exists therefore for researchers to fully contextualise the gender differences that exist in educational achievement within the over-riding contexts provided by social class and 'race'/ethnicity. The paper provides an example of how this can be done through a case study of 11-year-old children from a Catholic, working class area in Belfast. The paper shows how the children's general educational aspirations are significantly mediated by their experiences of the local area in which they live. However, the way in which the children come to experience and construct a sense of locality differs between the boys and girls and this, it is argued, helps to explain the more positive educational aspirations held by some of the girls compared to the boys. The paper concludes by considering the relevance of locality for understanding its effects on educational aspirations among other working class and/or minority ethnic communities.

How do young people understand and communicate their heterosexual readiness: A Mixed Methods Systematic Review

Young people’s understandings of sexual readiness are under-researched and their perspectives are often missing in debates about sexuality and sex education. Research to date has predominantly focussed upon age and socio-cultural predictors of sexual debut, thus failing to explain how young people themselves conceptualise their readiness for sexual relations. Synthesised in this review is the evidence from 26 studies which included young people’s perspectives of their readiness to begin sexual intercourse, undertaken using either quantitative or qualitative methods. Available evidence suggests that young people may not view initiating sex as problematic, focusing instead on the rewards sex brings and less on health concerns. Gender differences emerged in conceptualisations of love, parenthood, respect and abuse within relationships and were further mediated by social class and ethnicity. Age was also significant in young people’s accounts. Those under 16 years may not be ‘sexually ready’ because their own retrospective analyses suggest they experienced difficulty negotiating their risk of coercion or exploitation. More research exploring more deeply young people’s understandings of sexual readiness is required. We recommend a rights-based approach to support young people’s participation in the research process and to include their voices in the development of relevant sex education and services.

Does consideration of future consequences moderate the relationship between aggression and alcohol use in adolescents? Results from the United Kingdom

Background: An increasing body of literature suggests that those who give greater consideration to the future consequences (CFC) of their present behaviours are at a reduced risk of negative health outcomes. The present study examined whether CFC moderated the relationship between four domains of aggression and alcohol use in adolescents in the United Kindgom. Methods: Participants were 1058 adolescents from Northern Ireland. Participants completed questionnaires assessing: Anger; Hostility; Verbal Aggression; Physical Aggression; Consideration of Future Consequences; and alcohol use. Results: In line with extant research males scored significantly higher than females on measures of verbal and physical aggression, with no significant gender differences observed for other dependent measures. Results also revealed that CFC moderated the relationship between aggression and alcohol use, but only for females. Conclusions: These findings add to the increasing body of literature examining the temporal-health relationship. However more work is needed to help untangle the gender-specific effects.

O género e o uso das tecnologias da comunicação no ensino superior público português: as questões de género na perceção e avaliação das tecnologias da comunicação usadas para suporte à aprendizagem

O processo de convergência europeu da educação superior, mais conhecido por Processo de Bolonha, tem promovido mudanças profundas ao nível do Ensino Superior (ES). Entre as várias diretrizes propostas, destaca-se a necessidade de se usarem Tecnologias da Informação e Comunicação (TIC), no sentido de promover uma participação mais ativa, participativa e autónoma dos estudantes nos processos de aprendizagem. No entanto, a escassez de estudos abrangentes não permite a construção de uma visão fundamentada do uso de Tecnologias da Comunicação (TC) ao nível do ES. Surge assim a necessidade de se identificar e caracterizar o uso de TC, numa tentativa de construir uma imagem atual sobre quais as TC que são usadas, em que contextos, com que finalidades e como é que o seu uso é percecionado pelos estudantes. A tese aqui apresentada tem, assim, como objetivo principal procurar contribuir para uma compreensão mais alargada do uso de TC no Ensino Superior Público Português (ESPP), partindo das perceções dos estudantes e dando especial enfoque ao estudo da influência do género na perceção e avaliação do uso dessas tecnologias para suporte à aprendizagem. Para a prossecução dos objetivos propostos e, tendo presente a questão de investigação, desenvolveu-se um estudo nacional de cariz descritivo e exploratório, tendo os dados sido recolhidos e tratados com recurso a métodos quantitativos e, posteriormente, interpretados de forma mais qualitativa. A recolha de dados decorreu entre 27 de outubro de 2010 e 11 fevereiro de 2011, período em que esteve disponível para participação um questionário online dirigido a todos os estudantes do ESPP. Durante este período foram levadas a cabo diversas ações de divulgação que visaram, sobretudo, fomentar uma participação elevada neste estudo, o que se traduziu num total de 2.207 respostas validadas. Apesar das limitações identificadas, considera-se que as conclusões deste estudo são significativas sobre as características da realidade atual sobre o uso de TC por parte dos estudantes do ESPP, no sentido em que existiu uma elevada participação no questionário, a maioria das IESPP estão representadas, bem como se identificam muitas semelhanças entre os participantes e o universo em estudo. Os resultados alcançados permitem, assim, conhecer as TC usadas pelos estudantes e identificar diferenças de género na perceção desse uso, com especial evidência na perceção das atitudes, benefícios e problemas, bem como nas atividades e competências para o uso de TC. Conclui-se, ainda, que os alunos reveem utilidade nas TC que utilizam, exprimem grande concordância em relação aos benefícios e têm uma perceção positiva face aos impactos associados ao uso dessas TC.

Do Girls and Boys Perceive Themselves as Equally Engaged in School? The Results of an International Study from 12 Countries

This study examined gender differences in student engagement and academic performance in school. Participants included 3420 students (7th, 8th, and 9th graders) from Austria, Canada, China, Cyprus, Estonia, Greece, Malta, Portugal, Romania, South Korea, the United Kingdom, and the United States. The results indicated that, compared to boys, girls reported higher levels of engagement in school andwere rated higher by their teachers in academic performance. Student engagement accounted for gender differences in academic performance, but gender did not moderate the associations among student engagement, academic performance, or contextual supports. Analysis of multiple-group structural equation modeling revealed that perceptions of teacher support and parent support, but not peer support, were related indirectly to academic performance through student engagement. This partial mediation model was invariant across gender. The findings from this study enhance the understanding about the contextual and personal factors associated with girls' and boys' academic performance around the world.

Students who self-harm: coping style, rumination and alexithymia

Counsellors working with students or other young adults may encounter individuals who have self-harmed, either with suicidal or non-suicidal intent. Recent US studies reported rates of self-injury of up to 37% of the student population, but studies in the UK have focussed primarily on younger adolescents. This study examined reported self-harm incidents (scratching, cutting, poisoning, overdose etc) from a sample of 617 university students. A total of 27% reported at least one incident of self-harm, with almost 10% having harmed themselves while at university. Gender differences were not significant but psychology students reported significantly more self-harm than other students. Participants reporting self-harm scored significantly higher on maladaptive coping styles, rumination, and alexithymia (specifically difficulty in identifying emotions) and these differences were most marked for students reporting repetitive and recent self-harm. Rumination and Alexithymia factor 1 (difficulty identifying feelings) emerged as the most robust factors predicting self-harm status. Comments from students who self-harmed at university highlighted the importance of accessible services and academic staff support. The implications of these findings for counselling interventions are discussed, including challenging negative rumination tendencies and developing mindfulness skills.

Does more cycling mean more diversity in cycling?

In low-cycling countries, cycling is not evenly distributed across genders and age groups. In the UK, men are twice as likely as women to cycle to work and cycling tends to be dominated by younger adults. By contrast, in higher cycling countries and cities, gender differences are low, absent, or in the opposite direction. Such places also lack the UK's steady decline in cycling among those aged over 35 years. Over the past fifteen years some UK local areas have seen increases in cycling. This paper analyses data from the English and Welsh Census 2001 and 2011 to examine whether such increases are associated with greater diversity among cyclists. We find that in areas where cycling has increased, there has been no increase in the representation of females, and a decrease in the representation of older adults. We discuss potential causes and policy implications. Importantly, simply increasing cycling modal share has not proved sufficient to create an inclusive cycling culture. The UK's culturally specific factors limiting female take-up of cycling seem to remain in place, even where cycling has gone up. Creating a mass cycling culture may require deliberately targeting infrastructure and policies towards currently under-represented groups.

Diferença entre os géneros na análise cinemática e eletromiográfica do membro superior durante uma atividade diária de beber

As diferenças entre os géneros parecem surgir desde a origem da humanidade, quando a função do homem era caçar e da mulher fornecer cuidados às crianças e realizar trabalhos de cariz manual. O membro superior apresenta um papel primordial na execução da maioria das atividades relevantes para o ser humano, sendo pertinente a realização de avaliações mais objetivas do mesmo. Com a realização deste estudo pretendemos verificar se existem diferenças entre os géneros nos parâmetros eletromiográficos e cinemáticos do movimento durante uma atividade diária; perceber se os valores da eletromiografia e da cinemática do membro superior são dependentes do género à medida que a distância do objeto é alterada e ainda, levar a cabo a análise da atividade de beber. Para tal foram avaliados parâmetros de qualidade de movimento e parâmetros de recrutamento muscular em 15 indivíduos do género feminino e 15 indivíduos do género masculino com idades compreendidas entre os 18 e os 30 anos numa atividade de beber em três momentos diferentes. Para a análise cinemática foi utilizado o software Qualysis Motion Capture e para a análise eletromiográfica o software AcqKnowledge Analysis. Com os resultados obtidos constatamos que a percentagem de ativação muscular e os ângulos de flexão do ombro e flexão do cotovelo apresentam diferenças estatisticamente significativas (p<0.05) entre os géneros, sendo o grupo feminino a apresentar valores superiores. Aferiu-se também que a percentagem de ativação do músculo Deltoide Anterior parece ser influenciado pelo género (p<0.05) ao longo das três distâncias em estudo, sendo novamente o grupo feminino a apresentar valores superiores. Para além disto, aquando do movimento de alcançar, verificaram-se evidências estatísticas (p<0.05) do envolvimento do tronco em todas as distâncias de alcance do objeto, inclusive numa distância inferior ao comprimento do braço. Este estudo permitiu a descrição detalhada da eletromiografia e cinemática do movimento do membro superior de alcançar e transportar numa atividade diária, bem como uma comparação da mesma entre o grupo masculino e grupo feminino.

Ethical consumption (in)decisons

Consumers’ indecisions about the ethical value of their choices are amongst the highest concerns regarding ethical products’ purchasing. This is especially true for Fair Trade certified products where the ethical attribute information provided by the packaging is often unacknowledged by consumers. While well-informed consumers are likely to generate positive consumer reactions to ethical products and increase its ethical consumption, less knowledgeable buyers show different purchasing patterns. In such circumstances, decisions are often driven by socio-cultural beliefs about the low functional performance of ethical or sustainable attributes. For instance, products more congruent with sustainability (e.g., produce) are considered to be simpler but less tasty than less sustainable products. Less sustainable products instead, are considered to be more sophisticated and to provide consumers with more hedonic pleasures (e.g., chocolate mousse). The extent that ethicality is linked with experiences that provide consumers with more pain than pleasure is also manifested in pro-social social behaviors. More specifically through conspicuous self-sacrificial consumption experiences like running for charity in marathons with wide public exposure. The willingness of consumers to engage in such costly initiatives is moderated by gender differences and further, mediated by the chronic productivity orientation of some individuals to use time in a productive manner. Using experimental design studies, I show that consumers (1) use a set of affective and cognitive associations with on-package elements to interpret ethical attributes, (2) implicitly associate ethicality with simplicity, and that (3) men versus women show different preferences in their forms of contribution to pro-social causes.

Molecular characterization and phenotypic expression of mutations in genes for gonadotropins and their receptors in humans.

Gonadotropin hormones undergo important dynamic changes during life. Their rise during puberty stimulates gonadal steroid secretion, triggering the development of secondary sexual characteristics and the acquisition of fertility. The full spectrum of possible mutations and polymorphisms in the human gonadotropins and in their receptor genes has been described in recent years. Patients harboring these mutations display a very wide range of phenotypes affecting all aspects of the reproductive axis. An important insight provided by the careful study of these patients lies in the striking gender differences in the phenotypes associated with a given mutation. As a result, the careful study of these rare patients has allowed us to better define the respective roles of luteinizing hormone and follicle-stimulating hormone in normal human pubertal development and in the achievement of full fertility potential in either males or females. In this work, we describe briefly the known mutations in the genes for both gonadotropins and their receptors, and discuss their genotype/phenotype correlations in light of these important gender differences.
