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.

The solo WORK represents an investigation and inquiry into hybrid practice and performance in dance. WORK is the product and register of the author's Master of Arts by Research project undertaken at Deakin University (2010-2012). The embodied inquiry into the nature and potential of hybridity begins and returns to the body in both the physical and written performances. Rather than viewing hybridity and the hybrid body as a pastiche of poorly understood practices, processes and aesthetics, this investigation proposes the hybrid body and practices as one of positive expansion, inquiry, and development for both art form and artist alike.
WORK developed a new approach to movement practice and performance through a solo performance that used physical paradigms of endurance and work to integrate the normally divergent movement practices of contemporary dance, circus and improvisation. Through experiments of endurance in practice and performance WORK engaged in an experiment that placed the author's body as researcher, dancer, choreographer, performer, acrobat and more into the centre of her inquiry. The author's inquiry posed questions as to the potential or otherwise of the hybrid body in the creation of an individual idiom in dance, and challenged bodily endurance in solo performance practice.
This was a performance demonstration of what training-practice, performance-practice and performance might be from a hybrid perspective and also the physical and psychological performance of WORK. WORK is presented as functional, critical, challenging, demanding, and as an endurance event.
The discussion post performance focused on a new choreographic methodology (Studio-led practice as research for PhD study) for extending the potentiality of hybrid work physically - looking forward to removing bias and habitués and potentially creating a new paradigm aesthetically, physically, practically and critically.

This thesis provides critical empirical evidence on Bangladeshi family firm governance structures and their impacts on firm performance while taking political connections into consideration. Based on some theoretical argument the thesis presents some unique and robust results which are consistent with the Bangladeshi institutional characteristics.

The foraging benefits of coloniality, whereby colony members exchange information about food location, have been suggested as a primary factor influencing the evolution of coloniality. However, despite its longstanding popularity, this hypothesis has rarely been tested experimentally. Here, we conducted a field experiment in the wild Zebra Finch Taeniopygia guttata to test whether colonial birds are better at finding food than solitary individuals. We manipulated food patch location and directly measured foraging activity of many colonial and solitary parents at those patches using an electronic monitoring system. We provided nesting sites in excess to alleviate nest site competition and manipulated brood size to eliminate the possible correlation between brood size, nesting density, and individual quality (including foraging activity). We found that solitary birds found experimental food patches first, closely followed by colonial birds. Moreover, solitary parents adjusted the amount of food per nestling to experimental brood size, whereas colonial parents did not, although overall, nestlings were fed more per capita in colonial than in solitary nests. In addition, brood size and, to a lesser extent, nesting density negatively affected nestling growth. Therefore, with the effect of provisioning rate, sibling competition, and cost of coloniality combined, nestling mass was not affected by the brood manipulation in solitary nests, whereas nestlings were lighter in enlarged than in reduced broods in colonies. Our results therefore suggest that individuals settling in solitary nests were intrinsically better foragers and more optimal parents. While they do not invalidate the possibility of information transfer at colonies, our findings highlight the importance of considering settlement bias in future studies and add to the existing evidence that the effects of nesting density on fitness are both complex and multiple.

This paper examines the impact of FSA's (Financial Services Agency) recent policy changes on the efficiency and returns-to-scale (RTS) of Japanese financial institutions including banks, securities companies and bank holding companies. Three kinds of efficiency are investigated namely, technical efficiency (TE), pure technical efficiency (PTE) and scale efficiency (SE) using the non-parametric methodology named data envelopment analysis (DEA). The DEA analysis shows a substantial improvement in the overall efficiency of Japanese banks, albeit a significant difference of efficiency scores between the major/city banks and the regional banks. Results are robust to alternative specifications of efficiency and scale changes.
