Inspiratory muscle warm-up and inspiratory muscle training: separate and combined effects on intermittent running to exhaustion

In the present study, we examined the independent and combined effects of an inspiratory muscle warm-up and inspiratory muscle training on intermittent running to exhaustion. Twelve males were recruited to undertake four experimental trials. Two trials (Trials 1 and 2) preceded either a 4-week training period of 1 × 30 breaths twice daily at 50% (experimental group) or 15% (control group) maximal inspiratory mouth pressure (PImax). A further two trials (Trials 3 and 4) were performed after the 4 weeks. Trials 2 and 4 were preceded by a warm-up: 2 × 30 breaths at 40% PImax. Pre-training PImax and distance covered increased (P < 0.05) similarly between groups after the warm-up (~11% and ~5-7% PImax and distance covered, respectively). After training, PImax increased by 20 ± 6.1% (P < 0.01; d = 3.6) and 26.7 ± 6.3% (P < 0.01; d = 3.1) when training and warm-up were combined in the experimental group. Distance covered increased after training in the experimental group by 12 ± 4.9% (P < 0.01; d = 3.6) and 14.9 ± 4.5% (P < 0.01; d = 2.3) when training and warm-up interventions were combined. In conclusion, inspiratory muscle training and inspiratory muscle warm-up can both increase running distance independently, but the greatest increase is observed when they are combined.     

职业院校精准资助工作体系的建构与应用

目前职业院校资助工作存在的突出问题有资助对象认定较为简单、资助实施举措较为单一、资助管理模式较为粗放。据此,文章提出职业院校精准资助工作体系的建构:建构资助对象的精准认定体系、建构资助实施的精准方法体系、建构资助过程的精准管理体系。最后说明了职业院校精准资助工作体系的应用:在资助对象的认定上注重定量与定性结合、在资助实施的方法上满足学生个性化需求、在资助管理的手段上建立信息化工作系统。     

The effects of exercise in hypoxic and normoxic conditions on endothelin-1 and arterial compliance

The purpose of this study was to determine the effects of short-term normoxic and hypoxic exercise on plasma endothelin-1 and nitric oxide levels, and the relationship of arterial compliance and pulmonary artery pressure to endothelin-1. Seven endurance-trained males completed two incremental and two steady-state exercise tests performed at ventilatory threshold in normoxia and hypoxia (fraction of inspired oxygen = 0.14). Plasma endothelin-1was measured throughout steady-state tests. Arterial compliance using applanation tonometry, plasma nitric oxide and pulmonary artery pressure using Doppler echocardiography were measured before and after exercise. Small arterial compliance and pulmonary artery pressure significantly increased following exercise. There were no main effects of condition or time for plasma endothelin-1and nitric oxide levels. There were no significant relationships between plasma endothelin-1 and arterial compliance or pulmonary artery pressure. In conclusion, mechanisms other than the endothelial system may play a role in the exercise-induced changes in small artery compliance in this study population. Moderate hypoxia and a 30-minute steady-state exercise have limited effects on plasma endothelin-1 in endurance-trained males.

Positive emotions: passionate scholarship and student transformation

This paper challenges the practical and conceptual understanding of the role of emotions in higher education from the twin perspectives of transition and transformation. Focusing on the neglected area of positive emotions, exploratory data reveal a rich, low-level milieu of undergraduate emotional awareness in students chiefly attributed to pedagogic actions, primarily extrinsically orientated, and pervasive throughout the learning experience. The data conceive positive affect as oppositional, principally ephemeral and linked to performative pedagogic endeavours of getting, knowing and doing. A cyclical social dynamic of reciprocity, generating positive feedback loops, is highlighted. Finally we inductively construct a tentative ‘emotion-transition framework’ to assist our understanding of positive emotion as a force for transformational change; our contention is that higher education might proactively craft pedagogic spaces so as to unite the feeling discourse, the thinking discourse (epistemological self) and the wider life-self (ontological) discourse.     

National and international disability rights legislation: a qualitative account of its enactment in Australia

In this paper, a detailed analysis based on the lived experiences of the study participants and the researcher (each with vision impairment) in education, post school and in the pursuit for employment is developed. The policy discourses of disability legislation – both at national and international levels – are explored with particular reference to their enactment in Australia. The analysis focuses on the collective indifference to detached others, which is evident in the linguistic construction of people with disabilities in the United Nations [(2006). Convention of the Rights of Persons with Disabilities. New York: United Nations] and the Australian Standards for Education 2005 [Australian Department of Education, Science and Training. 2006. Disability Standards for Education 2005 Plus Guidance Notes. Accessed March 12, 2012. http://nla.gov.au/nla.arc-7692.]. Together, these elements reflect the neoliberal principles that cast a shadow over the discourses of the disability policies.     

Community‐based early intervention for children with behavioural,emotional and social problems: evaluation of the Scallywags Scheme

Scallywags is a community‐based, early intervention programme for young children (aged 3–7) with behavioural, emotional and social problems, which integrates work in the home and school with a parenting curriculum and direct work with children. A pre‐post intervention study across multi‐sites of 340 participants is reported. Using standardised measures, the study found statistically significant reductions in problems at home and school experienced by children who completed the programme, and in parental stress levels. Participation was found to be high and the project acceptable to parents, many of whom would be described as hard to reach. The rigorous evaluation of this real‐life service and its positive outcomes highlight the potential of such programmes to tackle the needs of these children and families, and help prevent longer‐term problems associated with early onset behavioural problems, including social exclusion, antisocial behaviour and educational failure.
