The mid-1990s marked a paradigm shift in the way physical activity is promoted, and walking is now considered the most suitable type of physical activity for widespread promotion. Accurate measurement underpins public health practice, hence the aims of this chapter are to: (1) provide a typology for the measurement of walking; (2) review methods to assess walking; (3) present challenges in defining walking measures; (4) identify issues in selecting instruments for the evaluation of walking and (5) discuss current efforts to overcome measurement challenges and methodological limitations. The taxonomy of walking indicates that secondary purpose walking is a more complex set of behaviours than primary purpose walks. It has many purposes and no specific domain or intensity, may lack regularity, and therefore poses greater measurement challenges. Objective measurement methods, such as accelerometers, pedometers, smartphones and other electronic devices, have shown good approximation for walking energy expenditure, but are indirect methods of walking assessment. Global Positioning System technology, the ‘Smartmat’ and radio-frequency identification tags are potential objective methods that can distinguish walkers, but also require complex analysis, are costly, and still need their measurement properties corroborated. Subjective direct methods, such as questionnaires, diaries and direct observation, provide the richest information on walking, especially short-term diaries, such as trip records and time use records, and are particularly useful for assessing secondary purpose walking. A unifying measure for health research, surveillance and health promotion would strongly advance the understanding of the impact of walking on health.

Using an ecological model of child participation and drawing on newsletter data from schools across the United States of America (USA), this chapter statistically explores five state factors linked with school protests against gun violence: (1) children’s neighbourhood opportunity; (2) race/ethnicity; (3) voter preference for either a Republican or a Democratic president; (4) child participation policies; and (5) gun laws/violence/ownership. The chapter explores factors linked to both student participation in protests and student nonparticipation in protests that take place at their schools. Three factors were found to be associated with participation and nonparticipation: children’s neighbourhood opportunity, voters’ preference, and participation policies. Findings suggest that Democratic-voting states, mediated by education opportunity, predict the frequency of student protests against gun violence. In Republican-voting states, where education opportunity does not mediate the frequency of school protests, students still organised and participated in protests but to a lesser extent. In addition, states with high overall children’s neighbourhood opportunity and voting student education board members are highly likely to have non-protesting students in schools with protests. The chapter presents five conclusions from these results for the positive and negative exercise of child participation rights and considers what further multilevel explorations can be done to further test the framework employed for this analysis.

The Court of Arbitration for Sport (CAS), created by the International Olympic Committee (IOC) in 1983, resolves disputes between athletes and national or international sports governing bodies. The purpose of this paper is to critically examine the history and functions of CAS, with a particular focus on the ways in which athletes’ rights are threatened by the IOC’s Code of Sports-Related Arbitration.

The author reviews relevant law literature and media sources.

The concept of lex sportiva (global sport law), general arbitration practices and controversies concerning CAS’s impartiality are investigated, and the “strict liability” principle that CAS applies to doping allegations is assessed. This analysis points to a long record of inconsistencies and contradictions in the history and function of CAS. The findings lead to questions of arbitration or litigation; confidential or public proceedings; specialist or generalist arbitrators; lex sportiva or international legal principles; precedential or non-precedential awards; and civil or criminal burden of proof.

These unresolved issues demonstrate how the IOC struggles to maintain supremacy over world sport by promoting sport exceptionalism, and provide possible grounds for athletes’ future challenges to CAS.

The purpose of this paper is to provide a comprehensive overview that demonstrates the prevention role of dietary fiber in type2 diabetes. Due to the frequent incidences of type2 diabetes and its related complications, a small percentage of reduction in the cases could save thousands of lives and economic loss spending on healthcare and medication.

A literature review has been performed over the electronic databases Medline PubMed and SciELO (The Scientific Electronic Library Online). The reference list of identified articles has also been reviewed. For this search, the following descriptors were considered: diabetes mellitus, hyperglycemia, diet therapy, dietary fiber and insulin sensitivity.

The updated publications indicated that valuable efforts have been done to clarify the beneficial effect of dietary fiber consumption on type2 diabetes. Dietary fiber plays a role as a promising alternative therapeutic means toward type2 diabetes mellitus prevention.

This review is unique in its comprehensive nature. This paper will reflect the role and mechanism of dietary fiber in the prevention of type2 diabetes.

The chapter presents a critical analysis of the functions of the Court of Arbitration for Sport (CAS), identifying how athletes who appeal to CAS for resolution of doping disputes face the problems of ‘stacked decks’ and ‘repeat parties’. A detailed critique of CAS's claim that it supports athletes' human rights, in the document titled ‘Sport and Human Rights: Overview from a CAS Perspective’, reveals the shaky ground on which the CAS authors based their argument. Detailed analyses of several recent doping cases reveal chronic problems of inconsistent and subjective awards, and, in the case of Chinese swimmer Sun Yang, issues of racist discrimination.

After the first transgender athletes participated in the 2020 Tokyo Olympics, some called for the immediate exclusion of transgender women in sports while others argue that this exclusion is discriminatory behaviour in violation of human rights law. Under current standards, the International Olympic Committee (IOC) has sought to address the balance between fairness and inclusion by allowing eligibility to be decided on a sport-by-sport basis for all transgender athletes (IOC, 2021). What if an international federation or national governing body concludes that transgender athletes should be prohibited or subjected to rigorous conditions for participation? Would those qualifications stand up to legal challenge by an affected athlete? Will some athletes have better legal protection based on the location of their challenge?

The United States (US) and United Kingdom (UK) have domestic legal provisions that protect transgender individuals from discrimination based on their gender identity whereas the European Union (EU) includes protections based on sex alone (Patel, 2021). This chapter will discuss transgender inclusion policies in Olympic sport and address how potential challenges to the policies will be handled in court using existing case law. Legal precedent in similar challenges is rare. However, when eligibility policies do not explicitly ban transgender athletes or appear to be a targeted response to a specific athlete or individuals, it becomes more likely that those policies will not be considered discriminatory. Courts are hesitant to interfere in a governing body's policies if that organization appears to have a legitimate reason for its sport governance decisions.

Achieving the elimination of racial differences in test performance, as set forth in the No Child Left Behind Act of 2001 (NCLB), requires education policies that engage the reality that African American test performances are not only about race but also about gender and residential status. In an effort to inform education policymaking with research that explores race–gender and residential inequality, I assess the growth of reading gaps in school and non-school contexts using a national and city sample of children from the Early Childhood Longitudinal, Kindergarten Cohort 1998–1999. I found that inequality in test performances was greater in the city than elsewhere, and African American boys shoulder a disproportionate educational burden related to city residency and enrollment in city schools. Additionally, children in city neighborhoods – where drugs and burglary are big problems – experience large shortfalls in reading in school and non-school contexts. I conclude with a discussion of the study’s implications for future educational policy, practice, and research, especially NCLB, which mandates that public schools achieve parity among racial groups by the end of the 2013–2014 academic year.
