Perceived health problems in swimmers according to the chemical treatment of water in swimming pools

The objective of this study was to determine which chemical treatment used for disinfecting water in indoor swimming pools had the least impact on users' perceptions of health problems, and which generated the greatest satisfaction with the quality of the water. A survey on satisfaction and perceived health problems was given to 1001 users at 20 indoor swimming pools which used different water treatment methods [chlorine, bromine, ozone, ultraviolet lamps (UV) and salt electrolysis]. The findings suggest that there is a greater probability of perceived health problems, such as eye and skin irritation, respiratory problems and skin dryness, in swimming pools treated with chlorine than in swimming pools using other chemical treatment methods. Pools treated with bromine have similar, although slightly better, results. Other factors, such as age, gender, time of day of use (morning and afternoon) and type of user (competitive and recreational), can also affect the probability of suffering health problems. For all of the above, using combined treatment methods as ozone and UV, or salt electrolysis produces a lower probability of perceived health problems and greater satisfaction.     

Effects of load mass carried in a backpack upon respiratory muscle fatigue

Purpose: The purpose of this study was to investigate whether loads carried in a backpack, with a load mass ranging from 0 to 20?kg, causes respiratory muscle fatigue. Methods: Eight males performed four randomised load carriage (LC) trials comprising 60?min walking at 6.5?km?h^?1 wearing a backpack of either 0 (LC₀), 10 (LC₁₀), 15 (LC₁₅) or 20?kg (LC₂₀). Inspiratory (P_Imax) and expiratory (P_Emax) mouth pressures were assessed prior to and immediately following each trial. Pulmonary gas exchange, heart rate (HR), blood lactate and glucose concentration and perceptual responses were recorded during the first and final 60?s of each trial. Results: Group mean P_Imax and P_Emax were unchanged following 60-min load carriage in all conditions (p?>?.05). There was an increase over time in pulmonary gas exchange, HR and perceptions of effort relative to baseline measures during each trial (p?p?>?.05). Conclusions: These findings indicate that sub-maximal walking with no load or carrying 10, 15 or 20?kg in a backpack for up to 60?min does not cause respiratory muscle fatigue despite causing an increase in physiological, metabolic and perceptual parameters.     

Degrees of value: comparing the contextual complexities of UK transnational education in Malaysia and Hong Kong

This paper reveals the complex diversity that underpins ostensibly similar transnational education programmes (TNE), through a comparison of UK TNE in Malaysia and Hong Kong. It draws on data from two different yet cognate studies on the role of UK universities in delivering higher education in Asia. Some fine-grained and informative differences between the ways in which ‘value’ in TNE is constructed in different host contexts is revealed. The paper brings to light the ‘voices’ of TNE students and graduates, which are very seldom heard. The arguments adapt and extend the concepts of education as a positional good, and as cultural capital. For various instrumental, intrinsic and personal reasons the authors discuss in detail, UK TNE is more highly valued in Malaysia than in Hong Kong. The paper makes a wider contribution to knowledge on the changing landscape of international higher education and the impact on social and personal (dis)advantage.     

Heroes of resiliency and reciprocity: teachers’ supporting role for reconceptualizing superhero play in early childhood settings

Superhero play is a specialised form of fantasy play with considerable appeal to young children. During superhero play, children have opportunities to pretend and often to play different types of roles within a safe and caring environment. When guided appropriately in an early childhood classroom, superhero play gives young children opportunities to gain a sense of mastery and empowerment as well as developmentally appropriate benefits by improving language skills, problem-solving and cooperation with peers. By recognising and modelling the characteristics of resiliency and promoting kindness with peers during superhero play, teachers can encourage children to be kind and resilient heroes to classroom friends. As today’s classrooms increasingly include diverse members, it is important for young children to understand and appreciate the peers they play and learn with at school. The result may be a richer learning experience and may break down barriers that can produce unfairness, bullying and aggressive behaviours. This article explores the essence of superhero fantasy play along with its benefits for young children. In addition, the article examines the challenge of superhero play in classrooms for early childhood educators by exploring teachers’ roles in play. A new pedagogy for supporting superhero play is introduced, addressing spiritual and educational concerns by suggesting ways in which teachers can increase resiliency, encourage new friendships and build classroom community among peers during play and classroom activities.     

Teaching Psychobiology at a Distance

Psychobiology is an area of knowledge that deals with the biological basis of behaviour. Its concretion as a specific area of study originates in the confluence and development of other areas such as physiological psychology, experimental and comparative psychology, ethology, biology and the neurosciences. For some, psychobiology would be that part of the neurosciences that deals with the study of the processes of emotion, motivation, cognition and learning. Others are of the opinion that it covers a much wider area, and that its objective is rooted in the study of all biological mechanisms that govern behaviour — and these, undertaken from a philogenetic and ontogenetic perspective.

In the last decade, we have witnessed the creation of psychobiology departments throughout the world. These departments participate in the teaching of faculties of medicine, psychology, biology and zoology. In some universities, these departments even contribute to the teaching imparted by the faculties of philosophy and educational sciences. Sooner or later, the universities teaching at a distance had to consider the creation of departments of psychobiology to attend to the up‐dating of the curriculum of diversive faculties.

In the National University of Education at a Distance, U.N.E.D. (Madrid, Spain) the teaching of psychobiology is entrusted to a department of the same name which started during the academic year of 1982–83. Even though the experience is very short to be able to advance a complete evaluation, the difficulties encountered in the organization of the form and content of different courses imparted by the department of psychobiology (D.P.) could be useful to the reader. Therefore, these difficulties must be understood within the educational model of teaching at a distance at U.N.E.D.     

Progress monitoring with objective measures of writing performance for students with mild disabilities

To adequately monitor progress in writing, a test must show stability and demonstrate a performance profile over time that parallels those of accepted criterion measures. This study investigated the technical adequacy of seven objective indexes of writing quality in monitoring the progress of 36 middle school (Grades 6-8) students with mild disabilities over a 6-month period. The stability of each index was assessed. Holistic ratings of the same writing samples and the Test of Written Language served as validation criteria. Three indexes were moderately correlated with holistic ratings, but were not sufficiently stable over time. Direct, objective writing assessment must be used with caution for progress monitoring, given our present lack of precision in measuring the complex task of writing.     

Equity and social exclusion measures in EU lifelong learning policies

ABSTRACT

The aim of this article is to examine how EU lifelong learning policies are trying to reach the vulnerable by looking at what measures against social exclusion they offer and how equitable these measures are. It is a qualitative study that focuses on policy documents that form the European Union’s legal and political frameworks of reference in the lifelong learning area since 1992. The document analysis has been complemented by semi-structured interviews with EU lifelong learning experts. The findings show that early school leavers and migrants are the main target groups in the policies, leaving many other groups at risk of being excluded from learning opportunities. There is not enough attention to measures addressing wider social phenomena. There is also an overemphasis on basic skills which are understood in a very narrow way as literacy and numeracy when referring to the vulnerable. We argue that a greater variety of measures as well as better targeted measures are needed to address the multiple and complex needs of the vulnerable. Such measures would allow a broader understanding of lifelong learning where those that are hardest to reach are offered learning opportunities independent of their personal and social circumstances
