The purpose of this review is to examine the effect of nutrition on mental functions of children and adolescents.

The approach taken is to evaluate published research on key dietary factors, including recent, rigorously designed supplementation studies.

The result of this analysis is that nutrition has potent effects on brain function. It is concluded that protein, iron, iodine, and the consumption of breakfast all impact on a child’s learning capability and behaviour. Moreover, recent research has identified additional, potent roles of micronutrients, such as essential fatty acids, minerals, and vitamins, in the prevention of learning and behavioural disorders. Among the latter, this review focuses particularly on attention deficit hyperactivity disorder.

While several controlled supplementation trials with supplementation are now available, the limitation of the present analysis is that more large‐scale trials are needed before final conclusions can be reached.

The practical implication of this review for health‐care providers, nutritionists, teachers, and parents at this time is that enough promising evidence has be accumulated to warrant a recommendation to include adequate levels of minerals, vitamins, essential fatty acids, and other nutrients in children’s diets to improve learning and behaviour.

This review is unique in its comprehensive nature and provides a synopsis of the power of diet in influencing learning and behavior for professionals and parents.

This chapter provides two case studies of online graduate student engagement where a community of learning is fostered using Bronfenbrenner’s (1979, 2001) ecological systems theory. The first case study explores an online graduate Sustainability Science course where students were provided with a space in VoiceThread to create video blogs (vlogs) and to extend course content with dialogue based on their values, relationships, and perspectives on issues like environmental degradation, social justice, and quality of life. The second case study surveys an online graduate course in Solar Energy, Technology, and Policy. These students completed a scholar-practitioner interview assignment of a solar energy expert, professional, entrepreneur, or policymaker. Both vlogging and scholar-practitioner interviews engaged graduate students in all of Bronfenbrenner’s (1979, 2001) ecological systems. For the vlogging assignment, the microsystem, mesosystem, and macrosystem were the most engaged; whereas for the scholar-practitioner interview assignment, the microsystem and exosystem were the most engaged. With respect to community building, both assignments fostered student-to-student interactions. The scholar-practitioner interview also fostered student-to-scholar-practitioner interactions, and, in some cases, student-to-alumni interactions. Innovative course assignments that engage professional, part-time graduate students with course content and other students, allow them to apply new knowledge, and broaden their professional connections are ideal.

The literature on precarious and insecure work rarely examines how workers with jobs in large bureaucratic firms experience insecurity. Current theories suggest two approaches. First, workers might focus on their individual occupation and detach their commitment from firms that no longer reciprocate long-term commitments. Second, employees might respond with increased organizational commitment because leaving an employer creates risks of uncertainty. Based on in-depth interviews with 22 financial services professionals, this paper refines our understanding of when workers focus on intra-organizational career development. This happens when large firms offer opportunities for advancement and foster loyalty. I develop the terms spiral staircase and serial monogamy career. A spiral staircase career results when workers take entrepreneurial approaches to advancement that include lateral job changes and vertical promotions within a firm. When the local labor market has multiple firms in their sector, career advancement may take an intermediate form, in which workers spend medium-to-long-term stints with multiple organizations. I call this the serial monogamy career. My research shows how sector characteristics and geography can impact worker commitment and mobility in insecure environments.

Socio-economic, health and environmental turbulences experienced during the past decades have caused major value chain disruptions, triggering multinational enterprises (MNEs) to rethink the footprints of their global operations and redesign for resilience. These developments have fueled a rapidly expanding scholarly literature on resilience. Yet, its conceptual understanding and practical utility remain highly fragmented, cross-disciplinarily disconnected and ambiguous. This study explores the intellectual structure of resilience research in business and management, relying on a systematic literature review approach based on bibliometric techniques and content analysis. A unique database consisting of 545 peer-reviewed articles published in 65 leading Academic Journal Guide (AJG) journals are analyzed. Based on the findings, three leading research communities dominate the resilience discussion in business and management. Moreover, the intellectual structure of the field through the most productive authors and top cited journal articles is discussed. Based on the results, five potential research avenues are suggested.

In recent decades, significant advances have been made at both the grassroots and professional levels of women's ice hockey in North America. Yet, despite recent achievements, such as the establishment of ‘professional’ leagues, and compelling narratives of progress, athletes and league organisers still face significant challenges. The barriers women face, such as reduced access to resources and opportunity, lack of legitimacy, and league instability, and a continued reliance on relationships with men's sporting leagues, such as the National Hockey League, suggest that women's ice hockey is accommodated into the game in ways that reinforce and perpetuate systems of gender, reproducing a neoliberal notion of failure. Using Halberstam's (2011) notion of failure as the place from which reform and transformation can take place, we offer a critical reading of the (re)formation of the National Women's Hockey League and the developments in women's (semi)professional ice hockey in North America.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.
