Erythropoietin concentration and arterial haemoglobin saturation with supramaximal exercise.

The aim of this study was to determine if the hypoxaemic stimulus generated by intense exercise results in the physiological response of increased erythropoietin production. Twenty athletes exercised for 3 min at 109 +/- 2.8% (mean +/- s) maximal oxygen consumption. Estimated oxyhaemoglobin saturation was measured by reflective probe pulse oximetry (Nellcor N200) and was validated against arterial oxyhaemoglobin saturation by CO-oximetry in eight athletes. Serum erythropoietin concentrations-as measured using the INCSTAR Epo-Trac radioimmunoassay-increased significantly by 28 +/- 9% at 24 h post-exercise in 11 participants, who also had an arterial oxyhaemoglobin saturation < or = 91% (P < 0.05). Decreased ferritin levels and increased reticulocyte counts were observed at 96 h post-exercise. However, no significant changes in erythropoietin levels were observed in nine non-desaturating athletes and eight non-exercise controls. Good agreement was shown between arterial oxyhaemoglobin saturation and percent estimated oxyhaemoglobin saturation (limits of agreement = -3.9 to 3.7%). In conclusion, short supramaximal exercise can induce both hypoxaemia and increased erythropoietin levels in well-trained individuals. The decline of arterial hypoxaemia levels below 91% during exercise appears to be necessary for the exercise-induced elevation of serum erythropoietin levels. Furthermore, reflective probe pulse oximetry was found to be a valid predictor of percent arterial oxyhaemoglobin saturation during supramaximal exercise when percent estimated oxyhaemoglobin saturation > or = 86%.     

Individual Action Planning in Initial Teacher Training: Empowerment or discipline?

The article explores the impact of Individual Action Planning (IAP) on Postgraduate Certification in Education student teachers, in terms of whether it can be seen as a process of empowerment or discipline. The context of changes in teacher education introduced by recent Governments is established and the literature on empowerment, discipline and education is reviewed. The findings of the reactions of a group of student teachers to the IAP process are reported, with a focus on whether they experienced Action Planning as enabling or controlling. The authors conclude that the main perception of IAPs by the student teachers has more to do with empowerment than discipline, but that neither concept fully encompasses those responses. They propose that further study is needed to explore whether a system of self-surveillance is operating through IAP.     

Establishing a successful physical activity program to recruit and retain women

Increasingly, health organisations and governing bodies in developed countries are paying serious attention to the problem of adult inactivity. Many of the programs designed to increase levels of activity, particularly amongst target populations, such as women, have not been systematically assessed for their effectiveness in recruiting women and helping them maintain activity levels. The purpose of this study was to determine what attracted and sustained women to participate in physical activity programs. Responses from a survey to sport and recreation program providers identified 64 successful programs in the state of Victoria, Australia. Eight of these programs were purposively selected for case study analysis. Data was collected from a focus group with women participants from each of these eight programs. Six core themes emerged from inductive content analysis of the focus groups. The most frequent participant responses related to the social aspects of the exercise environment. Women in the focus groups valued instructor professionalism and instructors’ technical knowledge, however, it was their awareness and sensitivity that participants appreciated most. This exploratory study is important because it reflects the voices of women talking about what made physical activity programs successful for them. The study raises critical questions that should be examined systematically through large-scale survey research and field-based intervention studies, which in turn should stimulate program development to encourage women in physical activity.     

Long‐Distance and Proximal Romantic Relationship Satisfaction: Attachment and Closeness Predictors

Relationship satisfaction was examined in college student long‐distance romantic relationships (LDRRs) and geographically proximal romantic relationships (PRRs). LDRR/PRR attachment style proportions and relationship satisfaction were similar. Multiple regression analyses revealed that low attachment avoidance contributed uniquely to high LDRR satisfaction and that low attachment avoidance, low attachment anxiety, and living apart contributed uniquely to high PRR satisfaction. Relational closeness was not a unique predictor of LDRR or PRR satisfaction.     

Tasks, topics and relevance judging for the TREC Genomics Track: five years of experience evaluating biomedical text information retrieval systems

With the help of a team of expert biologist judges, the TREC Genomics track has generated four large sets of “gold standard” test collections, comprised of over a hundred unique topics, two kinds of ad hoc retrieval tasks, and their corresponding relevance judgments. Over the years of the track, increasingly complex tasks necessitated the creation of judging tools and training guidelines to accommodate teams of part-time short-term workers from a variety of specialized biological scientific backgrounds, and to address consistency and reproducibility of the assessment process. Important lessons were learned about factors that influenced the utility of the test collections including topic design, annotations provided by judges, methods used for identifying and training judges, and providing a central moderator “meta-judge”.     

The impact of library services in primary care trusts in NHS North West England: a large‐scale retrospective quantitative study of online resource usage in relation to types of service

Background: Within NHS North West England there are 24 primary care trusts (PCTs), all with access to different types of library services. This study aims to evaluate the impact the type of library service has on online resource usage. Methodology: We conducted a large‐scale retrospective quantitative study across all PCT staff in NHS NW England using Athens sessions log data. We studied the Athens log usage of 30 381 staff, with 8273 active Athens accounts and 100 599 sessions from 1 January 2007 to 31 December 2007. Results: In 2007, PCTs with outreach librarians achieved 43% penetration of staff with active Athens accounts compared with PCTs with their own library service (28.23%); PCTs with service level agreements (SLAs) with acute hospital library services (22.5%) and with no library service (19.68%). This pattern was also observed when we looked at the average number of Athens user sessions per person, and usage of Dialog Datastar databases and Proquest full text journal collections. Discussion: Our findings have shown a correlation of e‐resource usage and type of library service. Outreach librarians have proved to be an efficient model for promoting and driving up resources usage. PCTs with no library service have shown the lowest level of resource usage.     

‘Please remember we are not all brilliant’: undergraduates’ experiences of an elite,research‐intensive degree at a research‐intensive university

Undergraduate research experiences are being incorporated into degree programs with increasing frequency. However, there has been little study into their effectiveness in preparing students for research or into the learning gains that students realise from one or more research experiences. We surveyed science students in an elite, research‐based undergraduate degree program at a research‐intensive university. These students complete six research projects during their degree and we aimed to delineate factors that students perceive as leading to either good or bad experiences. Two factors stand out as contributing to a successful research experience: the supervisor, with students reporting both pedagogic and affective benefits of good supervision; and the feeling that they are doing authentic science. Surprisingly, given the research‐intensive nature of this degree, the learning gains students report relate to both an appreciation of what research is like and life skills, such as time management, rather than scientific thinking skills.     

Church schools,educational markets and the rural idyll

Researchers have begun to explore the role that faith schools play in contemporary educational markets but the emphasis to date has been on urban rather than rural contexts. This article approaches the issue of marketisation through a qualitative case-study comparison of two Anglican primary schools in contrasting rural localities in England and Wales. Engaging with a range of stakeholders, including parents and pupils, the article explores reasons why the schools were valued, drawing on wider constructions of childhood, religion and rurality. The consequences of the schools’ popularity on factors such as traffic, parking, school ethos and local community ties are also considered. The findings of the study problematise some of the prevalent assumptions about marketisation, including the role of social class and geography in these processes. As such, the article makes an important contribution to the sociological literature on faith schools, rural schools and educational markets.
