Who is tech savvy? Exploring the adoption of smartphones and tablets: An empirical investigation

The present analysis performs a Multinomial Probit Model in order to observe which mobile technology qualifies across individuals. The findings indicate that individuals in family businesses prefer to combine both tablets and smartphones in their purchases, rather than separately. Younger individuals report an adoption preference towards smartphones, while older individuals are inclined towards tablets. The theoretical contributions encompass both the technology acceptance model (TAM) and the social cognitive theory (SCT). Individuals working in a family business exhibit a curious behaviour and they are becoming early adopters. TAM helps explain this behaviour as they tend to try new novelties exploring the potential usefulness they might derive; these technological advancements allow them to connect with customers and partners. By contrast, SCT helps gain a better understanding on young and old individuals' behaviour. The younger generations seem to be easily influenced by their peers with a tendency to technologies which are fun and allow them to build connections. Older individuals are equally influenced by their peers, with the difference that their social circle being more mature (e.g., business owners, professionals). This combined with the complexity of the technology orients them into adopting tablets more easily than smartphones.     

Boys negotiate violence and masculinity in the primary school

Abstract

In this paper, we contribute to the understandings of young masculinities by turning attention to the South African schooling primary school context. In the context of scarcity of interventions around violence in the primary school, we focus on how young boys construct, negotiate and experience violence. Notwithstanding dominant discourses around childhood innocence we argue that young boys are active participants in violent gendered cultures at school. We show how boys’ bodies are key sites for the enactment of violence and is especially a valuable resource in the context of food insecurity. The paper also shows the fluidity of masculinity as boys who are regarded as ‘victims’ can also defend and resuscitate masculinity that endorses violence. Implications for addressing young masculinities in the primary school within local context are considered in the conclusion of the paper.     

‘Charmer boys’ and ‘cream girls’: how primary school children construct themselves as heterosexual subjects through football

South African research on young children’s constructions of social identities illuminates the significance of play in the construction of gender identities. However, what remains largely understudied are the children’s construction of sexualities through play. The dominant discourse of ‘childhood innocence’ obscures the variegated understandings of the meanings children attach to sexualities. This paper will explore how some South African boys and girls aged 9–10 years construct themselves as active heterosexual subjects through football talk and play during break-time at school. The paper will demonstrate how the school playground is constructed by the ‘charmer boys’ as a ‘football space’ where they use football performance to impress and charm the ‘cream girls’ who are relegated to the margins as spectators of the football games. However, the paper will also argue that gender power relations are complex and that the position of the ‘creamers’ is infused with power as reflected in the role that they play as assessors of the boys’ performance.     

Good teaching as a messy narrative of change within a policy ensemble of networks,superstructures and flows

This paper examines ‘good teaching’ within a policy ensemble where teachers’ subjectification and practices are underpinned by new modes of evaluation and enforcement. Although the paper is written with specific concern for teachers in the Republic of Ireland, the literature demonstrates that concerns raised resonate internationally. Theoretical frameworks are drawn from Bernstein’s pedagogic device and ‘rules of evaluation’ (2000, p. 34) and the tyranny of number, networks and superstructures found in policy research. The study includes a limited analysis of the policy ensemble in ‘Austerity Ireland’ and contextual understandings and perspectives of a purposive sample of experienced teachers (n = 54). Critical analysis generated three themes: multiple perspectives about ‘good teaching’, a strongly perceived pedagogy of oppression and low ethical trust in reported interactions at some schools and with the state inspectorate. Conclusions position ‘good teaching’ within the super-complexity of a messy narrative of change and flows enacted with a diversity of inquirers and institutions. The study questions the role of state inspectors as arbiters of ‘good teaching’ and challenges the academy of teacher education in assuring productive discursive gaps for education as a social responsibility for public-interest values.     

Self-directed professional development – Hope for teachers working in deprived environments?

Self-direction has been identified as a potential key to the success of professional development of teachers, especially those working in deprived environments. This paper develops a model for self-directed professional development using interview data from 55 Zimbabwean A-level Science and Mathematics teachers. It focuses on teachers' decisions about using ICT in their own professional development. Grounded theory analysis suggests seven themes underlying such decisions making, in turn representing two major attractors of self-directed professional development. These were identified as classroom efficacy, i.e. the ability to teach effectively, and professional efficacy, i.e. the ability to relate effectively within the teaching profession. This paper explores the potential of using these attractors to stimulate self-directed professional development within formal professional development programmes especially in disadvantaged communities.     

Are intensified physical education sessions able to elicit heart rate at a sufficient level to promote aerobic fitness in adolescents?

The purpose of this study was to determine the effects of intensified physical education sessions on adolescents ages 11-16 years. They were divided into two experimental groups--high-intensity running group (HIRG) and high-intensity jumping group (HlJG)--and a control group (C). During the sessions, heart rate (HR) was monitored. There was no significant difference between mean HR for HIRG and HIJG, while the mean HR was significantly lower for C (p < .001). For both HIRG and HIJG, the mean HR was significantly higher for girls than for boys (p < .001). Our results suggested that these intensified physical education lessons require a high percentage of maximal HR in adolescents and can be used to improve aerobic fitness.     

The influence of distractor strength and response order on MCQ responding

Multiple-choice questions (MCQs) play a key role in standardised testing and in-class assessment. Research into the influence of within-item response order on MCQ characteristics has been mixed. While some researchers have shown preferential selection of response options presented earlier in the answer list, others have failed to replicate these results. This paper investigates a possible explanation for these mixed findings by assessing the influence of distractor strength on MCQ response order effects. A real-world assessment was administered to 232 undergraduates in which the response order within items was systematically varied. A generalised multilevel model was then used to show a significant interaction between distractor strength and response position with regard to response behaviour. Furthermore, the effect was found to be independent of student ability. These findings have implications for MCQ test construction, minimising the negative consequences of MCQ test exposure and promoting improved test-taking strategies.     

Velocity observer design for the consensus in delayed robot networks

The consensus problem for networks of multiple agents consists in reaching an agreement between certain coordinates of interest using a distributed controller. It may be desirable that all the agents find a consensus at a given desired leader coordinate (Leader Follower Consensus Problem LFCP), or it may be only necessary that they agree at a certain coordinates value (Leaderless Consensus Problem LCP). Consensus has many practical applications in robot networks systems, where the interconnection of the agents may present variable time delays, hence rendering the stability analysis and control design more complex. Another problem that may arise is the possible lack of velocity measurements. In this work, a Proportional plus damping injection (P + d) controller together with a linear velocity observer is introduced. Our approach is able to solve both the LFCP and the LCP in networks of robots modeled as undirected weighted graphs with unknown asymmetric (bounded) variable time delays. Local (semi global) asymptotic stability is proven and simulation results are provided to test the performance of the proposed scheme.
