Abandoning innovation activities and performance: The moderating role of openness

Firms are encouraged to continually initiate innovation activities as part of their new product development processes and to be open to the use of external knowledge sources. Yet, many are abandoned. Openness to external knowledge sources and the experience of abandoning innovation activities are, therefore, becoming a part of an organization’s reality and innovation strategy. In this paper, we aim to explore how the experience of having abandoned an innovation activity can affect innovation performance and the role two key dimensions of openness, external search breadth and formal innovation collaboration breadth, play. Using data from the UK Innovation Survey, we find that the experience of having abandoned an innovation activity leads to improved innovation performance and that this is negatively moderated by the two dimensions of openness. When external search breadth is high, i.e. when an organization engages with a higher number of different types of knowledge sources, the link between abandoning innovation activities and innovation performance weakens. Similarly, when formal innovation collaboration breadth is high, i.e. the breadth of a firm’s formal collaboration relationships is high, the link between abandoning innovation activities and innovation performance also weakens. We conclude by discussing the theoretical and practical implications of our findings.     

Gender violence in schools in the developing world

This paper explores gender violence in schools in what is commonly known as the ‘developing world’ through a review of recent research written in English. Violence in the school setting has only recently emerged as a widespread and serious phenomenon in these countries, with the consequence that our knowledge and understanding of it is embryonic; much of it remains invisible or unrecognized. Informed by research from elsewhere, we use theories of gender/sexual relations to provide a more coherent understanding of the issues, to point to absences and open up spaces for further research with the potential to contribute to strategies through which it might be addressed. We start by clarifying the purposes and the broad position adopted in writing this paper. Then, we trace the conceptual connections between gender/sexual relations and gender violence in schools, acknowledging the importance of locating understanding of the phenomena within the context of the school’s culture, its structures and processes. We organize the review using two overlapping categories: implicit gender violence, which relates to the everyday institutional structures and practices, and explicit gender violence, which relates to more overtly sexualized encounters. Both categories cover gender violence perpetrated by students on other students, by teachers on students, and by students on teachers. In the final section, the theoretical connections (and distinctions) generated by the research allow for a critical overview of the strategies that have been used to address the problem to date.     

Students with autism transitioning from primary to secondary schools: parents’ perspectives and experiences

The transition from primary to high school can be a challenging process for students with autism spectrum disorder (ASD). During this time, research-based practices like home–school collaboration are crucial in facilitating a smoother transition. However, existing research indicates that the transition from primary to high school is a period of anxiety and reduced support for students with ASD and their families. This article describes the experiences of parents of students with ASD in regard to this transition and home–school collaboration. Semi-structured interviews were carried out with 15 parents of children with ASD who attended mainstream government high schools in metropolitan Sydney. Through content analysis, parents were found to have received varying levels of transition support. Their experiences of home–school collaboration were, however, generally positive. Overall, it is recommended that parents’ knowledge of their children with ASD should be prioritised and utilised in transition planning. Findings also suggest that a greater implementation of practices including mandated transition planning and home–school collaboration in schools would contribute to more authentic inclusion of students with ASD.

Gender and socioeconomic status differences in university students’ perception of social support

Perceived social support has been shown to be one of the most important protective factors for emerging adult students during their transition to university. However, the relationships between perceived social support and dimensions of gender and family background, which have been shown to affect adjustment to college life, remain unexplored. The current study analyzes the effect of gender, parents’ education, and family income level on social support perceived by Spanish university students. The sample consisted of 575 women and 280 men, of average age 18.02 years (SD?=?0.52) enrolled in the first year of degree courses at the University of Santiago de Compostela (Spain). Three measures were used to assess various facets of perceived social support, namely perceived acceptance, social provisions, and support availability and satisfaction. Gender differences were identified for several perceived social support dimensions; women reported a wider social network, which should cover more diverse needs of social support. In addition, differences related to mother’s education and family income level emerged for the availability of support and perceived acceptance. The results highlight the different role of gender and family background in several dimensions of perceived social support during the transition to emerging adulthood.     

Internalized Racism,Perceived Racism,and Ethnic Identity: Exploring Their Relationship in Latina/o Undergraduates

For Latina/o undergraduates, ethnic identity is an important construct linked to self‐esteem and educational attainment. Internalized and perceived racism have been hypothesized to hinder ethnic identity development in Latina/o undergraduates. To assess if internalized and perceived racism were inversely related to ethnic identity, the author conducted a hierarchical linear regression with 373 Latina/o undergraduates. There was a significant relationship between internalized racism and ethnic identity. Findings indicate a need to challenge internalized racism in Latina/o undergraduates.     

Body fat measurement in elite sport climbers: Comparison of skinfold thickness equations with dual energy X-ray absorptiometry

Abstract

The aim of this study was to compare equations for estimating percentage body fat from skinfold thickness in elite sport climbers by assessing their agreement with percentage body fat measured using dual-energy X-ray absorptiometry (DXA). Skinfold thickness was measured in a convenience sample of 19 elite sport climbers [9 women and 10 men; mean age 31.2 years (s = 5.0) and 28.6 years (s = 3.6), respectively]. Percentage body fat was estimated using 17 different equations, and it was also measured by DXA. A significant inter-methods difference was observed for all equations, except for Durnin's equation in men (inter-methods difference: ?0.57% and ?0.29%; 1.96 s: 5.56 and 5.23 for Siri's and Brozek's equation, respectively) and women (inter-methods difference: ?0.67% and ?1.29% for Siri's and Brozek's equation, respectively), and for Wilmore's equation using Siri's body fat equation in women (inter-methods difference: ?1.86%). In women, the limits of agreement were lower when using Durnin's equation compared with Wilmore's equation (1.96 s: 3.86% and 5.13%, respectively). In conclusion, of the 17 studied equations, Durnin's equation was the most accurate in estimating percentage body fat in both male and female elite climbers. Therefore, Durnin's equation could be used to assess percentage body fat in elite sport climbers if more accurate methods are not available. The generalizability of the results is limited by the fact that the sample was not selected at random.     

Acute effects of aerobic exercise performed with different volumes on strength performance and neuromuscular parameters

The aim of the present study was to investigate the acute effect of the aerobic exercise volume on maximum strength and strength-endurance performance; and possible causes of strength decrements (i.e. central and peripheral fatigue). Twenty-one moderately trained men were submitted to a maximal incremental test to determine anaerobic threshold (AnT) and maximum dynamic strength (1RM) and strength-endurance (i.e. total volume load [TV]) tests to determine their baseline strength performance. Following, subjects performed six experimental sessions: aerobic exercise sessions (continuous running at 90% AnT) with different volumes (3?km, 5?km or 7?km) followed by 1RM or strength-endurance test in the 45° leg press exercise. Maximum voluntary isometric contraction (MVIC), voluntary activation (VA) level, contractile properties, and electromyographic activity (root mean square [RMS]) of the knee extensor muscles were assessed before and after aerobic exercises and after strength tests. TV was lower after 5?km and 7?km runs than in the control condition (12% and 22%, respectively). Additionally, TV was lower after 7?km than 3?km (14%) and 5?km (12%) runs. MVIC, VA, RMS, and contractile properties were reduced after all aerobic exercise volumes (～8%, ～5%, ～11% and ～6–14%, respectively). Additionally, MVIC, VA, and contractile properties were lower after strength tests (～15%, ～6%, ～9–26%, respectively). In conclusion, strength-endurance performance is impaired when performed after aerobic exercise and the magnitude of this interference is dependent on the aerobic exercise volume; and peripheral and central fatigue indices could not explain the different TV observed.     

Determinants and patterns of physical activity practice among Spanish university students

The purpose of the present study was to investigate the socio-demographic and lifestyle determinants of physical activity practice, as well as the motivations for being or not being physically active in Spanish university students. A representative sample of students from a Spanish university (n = 2,051; 42.1% males; mean age 21.9, s = 4.8 years) participated in the present cross-sectional study. A questionnaire including questions regarding lifestyle, dietary habits, parents' characteristics, and physical activity habits was administered to the students. The socio-demographic and lifestyle determinants of physical activity practice were assessed using multivariable logistic regression. 68.4% of men and 48.4% of women reported to practise physical activity in the present sample. Those who practised physical activity consumed more fruits and were less likely to be smokers compared to non-physically active students. Also, physically inactive men spent more time in front of the computer and physically inactive women spent more time in front of the TV and were more likely to be frequent alcohol consumers. Maternal educational level and maternal physical activity habits were also important determinants of physical activity practice among men and women respectively. In conclusion, physically active students tended to engage in other healthy habits in the present population, suggesting the clustering of healthy or unhealthy lifestyle factors among specific subgroups.
