A feel for the game – a Bourdieuian analysis of principal leadership: a study of Queensland secondary school principals

Educational leadership discourse has for sometime been the major intellectual pillar of what was once known as the field of educational administration. An examination of the postgraduate coursework programmes available to aspiring principal leaders at every Australian university supports such a contention. While this discourse does shed light on the ubiquitous concept of leadership, it does little to explain the context in which leadership theory is supposed to contribute to the operational environment of schools. This is where Bourdieuian scholarship is particularly helpful. By shedding light on the complex social space in which principal leaders function, Bourdieu’s concepts of habitus, field and capital are particularly helpful thinking tools. For a variety of reasons the economic field has held philosophical dominance for much of the last 30 years. This has impacted significantly on the work space of principal leadership and needs to be understood if the familiar narratives of leadership theory are to be of contextual use. When investigating the social space of contemporary principal leadership, my recent study of two sets of Queensland‐based principals will be used. The emergence of enterprise bargaining into the workspace of these principals will be used as a means by which to demonstrate the cross‐field contagion of the economic field on to the field of schools. The paper contends that the field of educational administration must endeavour to view leadership theory critically and contextually if the complexities associated with contemporary principal leadership practice are to be understood.

多维邻近性对跨区域技术创新合作的影响——基于中国共同专利数据的实证分析

区域间的邻近性是影响跨区域技术创新合作的重要因素.本文界定了区域间的认知邻近性、制度邻近性、地理邻近性,提出了多维邻近性对跨区域技术创新合作关系的概念模型,基于1999-2009年中国30个区域间的共同申请专利数据进行了实证研究.结果表明认知邻近性、制度邻近性、地理邻近性是跨区域技术创新合作的显著影响因素.其中国区域间认知邻近性过高,制约了跨区域技术创新合作的发展;区域间制度邻近性对跨区域技术创新合作有促进作用,而地方保护主义对中国跨区域技术创新合作的影响已不显著;地理邻近性仍然是跨区域技术创新合作的重要促进因素;区域创新能力相似性对多维邻近性与跨区域技术创新合作的关系有正向调节作用.     

Biomechanics of the ski cross start indoors on a customised training ramp and outdoors on snow

An effective start enhances an athlete's chances of success in ski cross competitions. Accordingly, this study was designed to investigate the biomechanics of start techniques used by elite athletes and assess the influence of different start environments. Seven elite ski cross athletes performed starts indoors on a custom-built ramp; six of these also performed starts on an outdoor slope. Horizontal and vertical forces were measured by force transducers located in the handles of the start gate and a 12-camera motion capture system allowed monitoring of the sagittal knee, hip, shoulder, and elbow kinematics. The starting movement involved Pre, Pull, and Push phases. Significant differences between body sides were observed for peak vertical and resultant forces, resultant impulse, and peak angular velocity of the shoulder joint. Significantly lower peak vertical forces (44 N), higher resultant impulse (0.114 Ns/kg), and knee joint range of motion (12°) were observed indoors. Although movement in the ski cross start is generally symmetrical, asymmetric patterns of force were observed among the athletes. Two different movement strategies, i.e. pronounced hip extension or more accentuated elbow flexion, were utilised in the Pull phase. The patterns of force and movement during the indoor and outdoor starts were similar.
