Sport development, systems, policies and pathways : an introduction to the special issue

Fundamentally sport development is about participation and promoting the opportunities and benefits of participation. Participation in sport and physical activity spans a wide range of contexts including the wholesomeness associated with the freedom of children’s play to the modification of sport to allow children to be children a little longer. The cycle of participation continues to junior and youth sport, where the rules, regulations and traditions of a sport become the foundation to protecting the “institution” of sport, to participation in senior competitions and ultimately, to elite and professional sport. Sport development research and practice therefore is concerned with all these manifestations of the sport experience. It logically follows that the purview of sport development is quite large and potentially complex. Moreover, it is possible to identify at least five themes that could be used to categorise sport development research. These themes include; policy, development through sport, development of sport, future patterns of sport delivery and marketing in terms of the relationship between professional sport and participation.

Reference functions and balanced concessions in bargaining

In bargaining, agents expect their concessions to be reciprocated. Using the 'reference function' concept of Thomson (1981), this paper constructs a class of solutions the outcomes of which lead to balanced concessions by agents as prescribed by the reference function adopted. The Kalai/Smorodinsky solution arises as a special case. Another solution in this class, which depends on the entire feasible set, is generated by using the centre of gravity as the reference function.

Discrete inequalities based on multiple auxiliary functions and their applications to stability analysis of time-delay systems

Abstract
This paper presents new discrete inequalities for single summation and double summation. These inequalities are based on multiple auxiliary functions and include the Jensen discrete inequality and the discrete Wirtinger-based inequality as special cases. An application of these discrete inequalities to analyse stability of linear discrete systems with an interval time-varying delay is studied and a less conservative stability condition is obtained. Three numerical examples are given to show the effectiveness of the obtained stability condition.

A comparison of search functions and other navigational tools provided on government websites

This paper reports the outcomes of a study that evaluated the effectiveness of search functions compared to other navigational tools available on government websites. The study used an observation exercise triangulated with a post observation interview. Results suggest that while there wasn't any significant difference in effectiveness between search functions and other navigational tools, the skill with which the search function is implemented and participants' familiarity with the website, are fundamental determinants of users' opinions. Implications of the findings for research and practice are discussed.

Stories seldom told: paediatric nurses` experiences of caring for hospitalized children with special needs and their families.

Stories seldom told: paediatric nurses' experiences of caring for hospitalized children with special needs and their families

Aims of the study. This study explored paediatric nurses' experiences of caring for children with special needs and their families in an acute care setting. The aim of the study was to increase understanding of nurses' experiences of caring for these children and their families. The study was designed to reveal the caring practices embedded within these relationships through exploring nurses' stories.

Study design/methods. Gadamerian hermeneutic phenomenology and feminist research principles were the approaches used to guide the study. Interviews were held with experienced paediatric nurses and interpretation of interview transcripts using a Gadamerian hermeneutic phenomenological approach resulted in the identification of four themes.

Findings. The four themes revealed were: Special Relationships; Multiple Dimensions of Who is Expert; Development of Trust Between Nurses and Families; and Feelings of Frustration and Guilt.

Conclusions. The study emphasized the context-specific nature of relationships between nurses and children and their families. The nurses spoke about the difficulties they encountered in their practice and some of the ways that they dealt with these problems. They discussed the things that they valued and those that made them feel guilty and frustrated. In doing so, they revealed their warmth, strength, humanity and caring.

Thresholds, incidence functions, and species-specific cues : responses of woodland birds to landscape structure in south-eastern Australia

Looking out from a vantage point across a large tract of forest gives a superficial impression of uniformity: the crowns of canopy trees follow the folds and contours of the landscape to provide a continuous cover of wooded vegetation. But this visual appearance belies the truth: forested landscapes are far from uniform. On closer examination, they comprise a complex mosaic of different vegetation types and and stands of different age-classes, differing structural features, and modified to a varying extent by human land-uses. Forests have a critical role in the conservation of biodiversity throughout the world (Peterken 1996; Laurance and Bierregard 1997; Lindenmayer and Franklin 2002) and a key feature contributing to their conservation value is the response of forest biota to the heterogeneity inherent in forested landscapes (Lindenmayer et al. 2006). Consequently, an understanding of the implications of landscape structure for the maintainance of species and ecological processes is an important foundation for forest management and biodiversity conservation.

Exponential stabilization of neural networks with various activation functions and mixed time-varying delays

This paper presents some results on the global exponential stabilization for neural networks with various activation functions and time-varying continuously distributed delays. Based on augmented time-varying Lyapunov-Krasovskii functionals, new delay-dependent conditions for the global exponential stabilization are obtained in terms of linear matrix inequalities. A numerical example is given to illustrate the feasibility of our results.

Special interests and mental health in autism spectrum disorders

Special interests (SIs) in autism spectrum disorders are a prevalent though relatively under-researched phenomenon. There was partial support for the hypotheses and factors influencing the relationship between SIs and mental health were identified. Findings contribute to a better understanding of SIs including their importance for individuals with ASD.

Restricted dissimilarity functions and penalty functions

In this work we introduce the definition of restricted dissimilarity functions and we link it with some other notions, such as metrics. In particular, we also show how restricted dissimilarity functions can be used to build penalty functions.
