Sport engagement, including tennis, and physical activity have been shown to have a positive influence on cognition in children. However, age has also been found to have a strong association with cognition in youth athletes. This study examines the threshold hypothesis by investigating the moderating role of age and maturation on the association between tennis experience and cognitive measures in Australian and German junior beginner to intermediate-level tennis players. The demographic information, which includes years of tennis experience, and anthropometrics (e.g. height and weight) was collected for 48 junior tennis players. A comprehensive cognitive testing battery was then completed to assess cognitive performance, with a principle component analysis used to determine an overall cognitive performance score. Multiple regression analyses were then performed to test the relationship between tennis experience and cognitive performance as well as the moderating effects of age and maturation. The results of this study indicate that the age and maturation rather than the exposure to tennis training are related to cognitive performance. Additionally, the positive relations of tennis experience to cognitive performance were stronger in younger participants, specifically those younger than 12 years old. Therefore, tennis may not provide a stimulus large enough for further cognitive improvement once players have developed a high level of cognitive performance. While age and biological maturity will largely dictate cognitive performance in adolescents, tennis experience may play some role in the cognitive performance of children (specifically <12 years of age).

Use Of Technology

Use of technology develops learner oral fluency, as well as their other learning skills. The recent research is on the role of modern technology in developing oral fluency of English among the students of intermediate level. The objective of the paper is to answer the question, what role technology plays in developing the oral fluency of learners? This study has been built on the hypothesis that technology has a positive influence on oral fluency, as by using technology learners enhance their oral fluency. In order to check our hypothesis this study used the quantitative data through questionnaire from 200 students (both male and female) aged between 17-19 years, at intermediate level from Government Emerson College Multan and Government Degree College Multan. The framework employed in this study is the input hypothesis by Stephen Krashen (1977). The hypothesis that technology plays positive role in developing oral fluency among students is proved in conclusion.

The Relationship

PurposeThe purpose of this study is to understand the development of social capital in an Arab business environment, and provide an in-depth description of the nature and role of three key Arabic business relationship characteristics (ehsan,et-mooneandwasta), their impact on each other and key influencing factors.Design/methodology/approachA qualitative research design was used, in which face-to-face semi-structured interviews were conducted with innovation teams (22 team members) at six industrial small and medium-sized enterprises in Saudi Arabia. The interviews were recorded and transcribed, then analyzed (thematic coding) through NVivo.FindingsThe findings suggest thatwasta,ehsanandet-moonealign closely with the three social capital dimensions (structural, cognitive and relational); thus, developing these three relationship characteristics most likely results in developing social capital. The findings also expand the description of the three business relationship characteristics. Moreover,ehsan,et-mooneandwastaappear to influence each other, and are affected by other factors such as an individual’s age and position, and the duration of the relationship.Ehsanhas a positive influence on the development ofet-moone, while the existence ofet-mooneappears to be necessary for the establishment ofwasta-capital. A high level ofehsanmight influence the relationship betweenet-mooneandwasta-use and limit the negative usage ofwasta.Practical implicationsInternational managers can improve the level ofehsanin their organizational and business relationships through assigning incentives and playing the role of moral champion to encourageehsanbehavior. Managers aiming to increaseet-moonemay choose team members with a high level ofehsan, emphasizing the development of personal relationships, and providing opportunities for socialization both inside and outside the workplace. A high level ofehsanandet-moonewill assist managers to develop and usewasta.Originality/valueThis study makes a threefold contribution to the literature. First, it provides an expanded description of the three Arabic business relationship characteristics and how they align closely with the dimensions of social capital.Wastaaligns with the structural dimension andehsanaligns with the cognitive dimension, whileet-moonealigns closely with the relational dimension. Second, it suggests and shows how the three relationship characteristics might interact with each other.Ehsanappears to influenceet-moone, and also the relationship betweenet-mooneandwasta.Et-mooneappears to have a positive influence onwastause. Third, the findings also indicate that there might be other factors (e.g. age and position) that influence the interactions between the three business relationship characteristics.

Role Of Religion

Protestantism has expanded rapidly in Brazil in recent decades. The question we tackle in this paper is whether Protestantism has had a positive influence on male earnings in this setting, either through its influence on health and productivity, by way of social networks or employer favor and reduced discrimination, or through other mechanisms. We tackle the problem of the selectivity of religious conversion and affiliation using microdata from the Brazilian censuses of 1970, 1980, 1991, and 2000, and analyzing the association between Protestantism and earnings at the group rather than the individual level. Our results show a strong association between the proportion of Protestants in a region, and the earnings of men in one educational group: those with less than five years of education. Upon introducing race into our models, we found that the association between religion and the earnings of less educated men is concentrated in regions in which there is a substantial non-white population. The relationships we have uncovered contribute to the literature on racial inequality and discrimination in Brazil, which to date has given little space to the role of religion in moderating the pernicious effect of race on economic outcomes in Brazil. The substantial association we found between religion and earnings contrasts with much of the research that has been carried out on the influence of religion on earnings in the United States.

Novel Protein

Brinker (Brk), a novel protein with features of a transcriptional repressor, regulates the graded response to Decapentaplegic (Dpp) in appendage primordia of Drosophila. Here, we show that in the embryo brk also has differential effects on Dpp target genes, depending on the level of Dpp activity required for their activation. Low-level target genes, like dpp itself, tolloid and early zerknullt, show strong ectopic expression in ventrolateral regions of brk mutant embryos; intermediate-level target genes like pannier show weak ectopic expression, while high-level target genes like u-shaped and rhomboid are not affected. Ectopic target gene activation in the absence of brk is independent of Dpp, Tkv and Medea, indicating that Dpp signaling normally antagonizes brk's repression of these target genes. brk is expressed like short gastrulation (sog) in ventrolateral regions of the embryo abutting the dpp domain. Here, both brk and sog antagonize the antineurogenic activity of Dpp so that only in brk sog double mutants is the neuroectoderm completely deleted.

This study explores the relationships between bricolage, firm performance and growth opportunities in contexts characterized by extreme resource scarcity. Using a sample of 160 Palestinian female entrepreneurs as representative of entrepreneurs acting in extremely resource-deprived environments, we find that bricolage has a positive influence on firm performance. Further, as predicted in the hypotheses, the role of bricolage differs depending on the type of strategy the firm develops. When firms seek to introduce new products/services or modifications in their current products/services, a high level of bricolage hinders performance. Conversely, when firms seek to expand by introducing their current products/services in new markets and opening new locations, bricolage enhances performance. This study offers a more nuanced understanding than previous research of the role of bricolage in contexts of extreme resource constraints.

Biological rhythm has contributed in evolution process of humankind and has created certain distinct capabilities and preferences in shaping his phycho-psychological reactions. On the basis of behavioural activities, reactions, preferences and performances during the day-night cycle, individuals are classified in chronotype as morning type (M type) and evening type (E type). Such a differentiation has been hypothesised to contributing to individual differences at the cognitive, affective and conative levels. The present study was an attempt to further study such differentiation in terms of neuro cognitive performance by using the most advanced psycho-physiological measures. The participants of both chronotypes, morning and evening were classified and later subjected to cognitive testing by using the Cambridge Neuropsychological Test Automated Battery in the morning and the evening session under repeated measure design. The study revealed that performance on neuro cognitive functions; Planning and working memory, Decision-making and response control, and Motor skills get effected differently by their biological rhythm cycle and thus under performance in these functions can be attributed to maladaptation of biological rhythm termed as biological dysrhythmia. The study also highlights the role of this behavioural maladaptation in moderating operational efficiency of soldier in combat situation.

This article uses the concepts of ‘transnational social fields’ and ‘habitus’ to explore the multifaceted role families play in shaping the aspirations of onward migrating youth. The article draws on biographical life history interviews conducted with the children of Iranian migrants who were raised in Sweden but moved to London, UK as adults. The findings of the study suggest that from a young age, all the participants were pressured by their parents to perform well academically, and to achieve high level careers. These goals were easier to achieve in London than in Sweden for several reasons. Interestingly, however, participants’ understandings of what constituted success and their motivations for onward migration were nuanced and varied considerably by gender. The study contributes to an understanding of the role of multi-sited transnational social fields in shaping the aspirations of migrant youths, as well as the strategies taken up by these migrants to achieve their goals.

And Behavior

Summary Although sport can promote moral values and prosocial behavior in youth, numerous research shows that sports engagement alone does not guarantee that outcome. Instead of striving for fair-play and sport excellence which not exclude justness, solidarity and moral integrity, contemporary sport frequently follows the Lombardian ethic, where „winning isn’t everything, it’s the only thing”. Moral pause or bracketed morality, as described in sport, refers to the phenomenon of tolerance and acceptance of aggressive behavior or cheating, that will be morally condemned outside sports arenas. Accordingly, lower levels of moral reasoning and behavior have been identified in athletes and non-athletes in the sports-related situation in comparison to other life situations; in athletes when compared to non-athletes, in more experienced athletes, high-level athletes, team-sport athletes, and male athletes. Moral reasoning and behavior of athletes are influenced by contextual and personal factors, with coaches having a particularly important role to play. The positive influence of sport on the moral development of athletes might be related to pre-service and in-service education of coaches how to develop adequate moral atmosphere, and how to plan for moral decision-making as an integral part of everyday practice.
