The effects of training on performance and performance-related states in individual elite athletes: A dynamic approach

Abstract

There are difficulties undertaking controlled training studies with elite athletes. Thus, data from non-elite performers are often presented in scientific journals and subsequently used to guide general training principles. This information may not be transferable or specific enough to inform training practices in an individual elite athlete. However, the nature of athletic participation at elite levels provides the opportunity to collect training data, performance-related variables, and performance data of elite athletes over long periods. In this paper, we describe how dynamic linear models provide an opportunity to use these data to inform training. Data from an elite female triathlete collected over a 111-day training period were used to model the relationship between training and self-reported fatigue. The dynamic linear model analysis showed the independent effects of the three modes of triathlon training on fatigue, how these can change across time, and the possible influence of other unmeasured variables. This paper shows the potential for the use of dynamic linear models as an aid to planning training in elite athletes.     

Engaging suppliers in CRM: The role of justice in buyer–supplier relationships

Given the crucial role of suppliers in collaborative supply chains, it is surprising that little attention has been paid to the nature and management of supplier relationships in the implementation of a retailer's Customer Relationship Management (CRM) strategy. To address this gap in the extant literature, the theory of organizational justice is used to explore the extent to which perceived fairness in buyer–supplier relationships supports or inhibits supplier engagement with the CRM process. The rationale is that suppliers who feel fairly treated by key retail customers are more likely to invest resources in the acquisition and use of data central to the retailer's CRM strategy. By empirically testing a conceptual model linking downstream CRM to upstream SRM, the results provide evidence to indicate that customer data use is significantly influenced by perceptions of fairness, particularly with respect to the distribution of rewards, and the transparency of decision-making processes. As a key criticism of CRM centers upon the failure of organizations to exploit the full potential of customer data, the results highlight the usefulness of understanding the relational linkages between buyers and suppliers and the consequential behavior of suppliers in terms of engagement with customer data vital to the success of retailers’ CRM strategies.     

Intercultural PhD supervision: exploring the hidden curriculum in a social science faculty doctoral programme

International knowledge markets rely heavily on a ready supply of highly mobile doctoral students, many of whom are from the global South, to bring in revenue. The supervision of these PhD students, however, can reproduce neo-colonial knowledge relations, often in subtle ways. In settler nations, international PhD students may find that they are assigned subaltern status in their university departments and this can have a significant impact on their learning. This paper explores the experiences of a group of international PhD students in a social science faculty in a New Zealand university during the first two years of their doctoral studies. It examines how they responded to the displacement of their cultural values and priorities, the way they navigated intercultural engagements with supervisors, and their ensuing relationships with indigenous and ethnic allies in the faculty. Despite considerable pressure to conform to the dominant modes of academic knowledge production that characterise universities in settler nations, it is concluded that international students find ways of speaking out, often in highly coded forms, that complicate their subaltern academic status.     

Friendships for wellbeing?: parents’ and practitioners’ positioning of young children’s friendships in the evaluation of wellbeing factors

ABSTRACT

Friendship matters for young children’s development, learning and experience of wellbeing. This paper emphasises the significance of young children’s friendships for their wellbeing, especially in the context of early years settings. Findings are presented from two online questionnaires developed for the project, in which 155 parents/carers and 285 practitioners in England expressed their perceptions of what matters for young children’s wellbeing. Data shows some ambivalence in the views of both parents/carers and practitioners about the importance of friendship in this context. Both groups gave low prioritisation to ‘the company of friends’ for children’s wellbeing. As friendships are of central importance to young children themselves, this could suggests that adults and children may have different priorities, which raises questions about the extent to which young children’s friendships are seen as important by adults. The paper concludes by proposing the need for practitioners in particular, but also parents, to consider their roles and priorities for children’s lives within schools and nurseries, including how they might sensitively support and facilitate children’s friendships in play, activities, transition and everyday life.     

What really matters for students’ school satisfaction in Bangladesh?

School satisfaction is the reflection of students’ comprehensive evaluation of their school experience. This study reports the level of school satisfaction among students in Grades 6 and 8 in Bangladesh to perceive and the factors that might contribute to it using a cross‐sectional research design. A 61‐item survey questionnaire was utilized to collect data. The students’ mean score on the school satisfaction subscale of the Multidimensional Students’ Life Satisfaction Scale equated to a slightly positive attitude towards school. Three demographic factors including students’ academic achievement, gender, and grade level; and two school climate factors of perceived teacher–student relationship, and perceived academic support, emerged from the multiple regression analysis. The study findings are discussed from the perspective of self‐determination theory with implications for practice and avenues for future research offered.     

A mixed design reveals that glucose moieties facilitate extinction of a conditioned taste aversion in rats

Separate groups of water-deprived rats had four trials with 15-min access to 0.0073 M saccharin, 0.3 M alanine, 0.3 M glucose, 0.1 M maltose, 0.3 M fructose, 0.06 M sucrose, or 0.03 M Polycose. Trials 1–3 were followed by injections of either 0.15 M LiCl (1.33 ml/100 g b.w., i.p.) or saline; Trial 4 (Test) was CS only. Extinction included either 48-h access to water alone or to the appropriate CS, both followed by a 24-h, two-bottle choice of CS and water. This 3-day cycle was repeated five to six times. All rats acquired comparable conditioned taste aversions (CTAs), but extinction rates varied with the test and the taste CS. No CTA extinguished during the two-bottle choices following 2 water days. During one-bottle CS exposure, all CTAs extinguished, but the aversion continued longer in the probe two-bottle tests. Intake of glucose moieties recovered rapidly, often in two cycles; the other CSs took four to six cycles. Thus, CTA extinction varies with the nature of the taste CS.     

Inclusive educational leadership to establish a co-operative school cluster trust? Exploring perspectives and making links with leadership for learning

ABSTRACT

One remarkable feature of the contemporary school landscape in England is the number of schools that have chosen the co-operative framework to shape their work and relationships. When a group of schools decides to become a co-operative trust, leadership challenges arise both in the process of establishing an inclusive collaborative cluster and in living out co-operative values. To add to the limited literature on co-operative school leadership, a study in a school cluster trust explored headteachers’, governors’ and teachers’ perspectives and beliefs through interviews, group discussions and questionnaires. These data sources revealed some of the motivations for, benefits of, and strategies to support inter-school collaboration guided by the co-operative values of democracy, solidarity, equality, equity, self-help and self-responsibility. Importantly, a range of perspectives on the extent to which leadership was viewed as, and appeared to be, an inclusive practice undertaken by all members of the cluster was identified. A particular contribution of this work is that it exemplifies resonances between the values and principles of the co-operative movement and those of the Leadership for Learning framework. Since these two models are being increasingly adopted and integrated into a variety of educational settings, the research findings may inform leadership practice more widely.
