Screening for risk of low energy availability in athletic and recreationally active females in Ireland

ABSTRACT

Introduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required.     

The Great Sphere: Education against Servility

Educational practices that encourage children to understand ethical diversity commonly conflict with the parental desire to instil unswerving identification with a particular way of life. This paper examines whether the scope of parents' rights to educational choice includes the option of vetoing such practices. Although parents' rights are no less important than the rights of their children, the option of denying children experiences that would expose them to ethical diversity cannot be rightfully claimed by any parent without repudiating the egalitarian basis of rights discourse.     

A journal is a club: a new economic model for scholarly publishing

A new economic model for the analysis of scholarly publishing – journal publishing in particular – is proposed that draws on club theory. The standard approach builds on market failure in the private production (by research scholars) of a public good (new scholarly knowledge). In this model, publishing is communication, as the dissemination of information. But a club model views publishing differently: namely as group formation, where members form groups in order to confer externalities on each other, subject to congestion. A journal is a self-constituted group, endeavouring to create new knowledge. In this sense, a journal is a club. The knowledge club model of a journal seeks to balance the positive externalities of a shared resource (readers, citations, referees) against the negative externalities of crowding (decreased prospect of publishing in that journal). A new economic model of a journal as a knowledge club is elaborated. We suggest some consequences for the management of journals and financial models that might be developed to support them.     

Racism and citizenship education in Northern Ireland

Racist attitudes towards, and attacks on, the minority ethnic populations in Northern Ireland (NI) have increased dramatically over the last number of years. Despite the increased media attention regarding racist attacks, the fallacy that racism is not a major problem in NI is an enduring one. However, there is a growing recognition that minority ethnic communities experience a diverse range of racial harassment. Education is a mode promoted by national and European governments as the vehicle in which anti-racism programmes can be delivered. This article suggests the impending introduction of a statutory citizenship education (CE) component to the revised NI curriculum from September 2007 can play an important role in tackling the high levels of racism being experienced by the minority ethnic population in NI.     

Educational services for mentally handicapped children in Northern Ireland: A survey of provision

Abstract

Until April 1987 mentally handicapped children were legally excluded from education in Northern Ireland. Provision was made instead in special care schools administered by social services authorities. This contrasts with the position in the rest of the UK where all children have been educated in schools administered by education authorities since the early 1970s. A survey was conducted to investigate aspects of provision in special care schools. Comparative samples of special schools for children with mental handicap in England, and special schools for other categories of children with special needs in Northern Ireland were also surveyed.

Results show that the special care school pupils were disadvantaged often seriously, compared with the other samples. Staffing ratios were inferior in most respects of provision. Other resources were often criticized by head teachers as inadequate. The special care school transport system was also shown to be seriously deficient, causing the length of the school day to be reduced for a very large proportion of pupils. The inadequacies identified impinged particularly on severely and profoundly handicapped pupils, despite earlier Government arguments that the interests of this group could be damaged in a transfer to education.

Nearly one fifth of the special care school population were aged 19 and over, and nearly one third of the profoundly handicapped pupils were 19 or over. In many cases adults and children shared the same facilities.

These results are compared and contrasted with Government documents which claimed parity of provision in special care schools and special schools in England, and which adopted a stated policy of normalization in the development of services for the mentally handicapped.     

“大球理论”与教育中父母及子女的权利

“大球理论”是在“自由教育”理论的基础上提出的。“大球理论”认为,父母对子女教育的希望和理想并不意味着要为子女规定固定的成长模式。父母拥有选择子女接受何种教育的权利;但同时,子女也有接受教育的自主权。关于家长在子女教育上的权利,应该既反对压制子女,同时也要公正地对待父母对孩子的殷切希望和他们为抚养子女做出的牺牲;关于子女受教育的自主权,应重视从小培养他们的自主意识,使之懂得追求心灵的自由。     

Effect of sex and fatigue on muscle stiffness and musculoarticular stiffness of the knee joint in a young active population

The purpose of this study was to investigate the influence of sex and fatigue on knee extensor peak torque (PT), muscle stiffness (MS) of the vastus lateralis (VL) and knee joint musculoarticular stiffness (MAS) in young adults. Twenty-two male and 22 female recreational athletes participated. Males were characterised by higher relaxed [pre-: males 364.43 (52.00) N · m^–1, females 270.27 (37.25) N · m^–1; post-: males 446.75 (83.27) N · m^–1, females 307.39 (38.58) N · m^–1] and contracted [pre-: males 495.07 (71.04) N · m^–1, females 332.34 (85.42) N · m^–1; post-: males 546.37 (90.74) N · m^–1, females 349.21 (85.55) N · m^–1] MS of the VL, and knee joint MAS [pre-: males 1450.11 (507.98) N · m^–1, females 1027.99 (227.33) N · m^–1; post-: males 1345.81 (404.90) N · m^–1, females 952.78 (192.38) N · m^–1] than females pre- and post-fatigue. A similar finding was observed in pre-fatigue normalised knee extensor PT [pre-: males 2.77 (0.42) N · m kg^–1, females 2.41 (0.40) N · m kg^–1, post-: males 2.53 (0.54) N · m kg^–1, females 2.26 (0.44) N · m kg^–1]. After the fatigue protocol, normalised knee extensor PT and knee joint MAS decreased, whilst relaxed and contracted MS of the VL increased in both sexes. These observed differences may contribute to the higher risk of knee injury in females and following the onset of fatigue.
