Over the last ten years, the corporate governance context in most Western countries has changed as a result of irregularities, increased regulation, heightened societal expectations and shareholder activism. This paper examines the impact of the changing context on the role of chairmen of supervisory boards in the Netherlands. Based on a combination of thirty semi-structured interviews with board members of leading Dutch corporations and secondary data on the position of supervisory board chairmen at the top-100 listed firms in the Netherlands, the study reveals that board chairmen have become increasingly involved in both their control and service roles. While the demographics (i.e., age, tenure, gender and nationality) of chairmen have hardly changed over the last decade, chairmen are spending considerably more time on boards and committees, have reduced the number of board interlocks and have become more active on the forefront of the corporate governance discussion. The paper highlights several implications for scholars and practitioners.

During the last decade, globalisation and liberalisation of financial markets, changing societal expectations and corporate governance scandals have increased the attention for the fiduciary duties of non-executive directors. In this context, recent corporate governance reform initiatives have emphasised the control task and independence of non-executive directors. However, little attention has been paid to their impact on the external and internal service tasks of non-executive directors. Therefore, this paper investigates how the service tasks of non-executive directors have evolved in the Netherlands. Data on corporate governance at the top-100 listed companies in the Netherlands between 1997 and 2005 show that the emphasis on non-executive directors' external service task has shifted to their internal service task, i.e. from non-executive directors acting as boundary spanners to non-executive directors providing advice and counselling to executive directors. This shift in board responsibilities affects non-executive directors' ability to generate network benefits through board relationships and has implications for non-executive directors' functional requirements.

Purpose: This paper provides a selective annotated bibliography that summarises journal articles which have employed either the theory of reasoned action or the theory of planned behaviour to circumstances which are relevant to business activities. Design/methodology/approach: Searches were conducted on the EBSCO Host and ProQuest databases to identify papers that had used either the theory of reasoned action or theory of planned behaviour in their methodology. The bibliography was separated into three categories- financial decision making, strategic decision making, and professional decision making. Implications: The information presented in this paper is intended to assist and facilitate further research by broadening the awareness of the literature and providing examples of the application of the theory as it has been employed in prior research.

This study aimed to clarify the relationship between the mechanical environment at the fracture site and endogenous fibroblast growth factor-2 (FGF-2). We compared two types of fracture healing with different callus formations and cellular events using MouseFix(TM) plate fixation systems for murine fracture models. Left femoral fractures were induced in 72 ten-week-old mice and then fixed with a flexible (Group F) or rigid (Group R) Mouse Fix(TM) plate. Mice were sacrificed on days 3, 5, 7, 10, 14, and 21. The callus volumes were measured by 3D micro-CT and tissues were histologically stained with hematoxylin & eosin or safranin-O. Sections from days 3, 5, and 7 were immunostained for FGF-2 and Proliferating Cell Nuclear Antigen (PCNA). The callus in Group F was significantly larger than that in Group R. The rigid plate allowed bone union without a marked external callus or chondrogenesis. The flexible plate formed a large external callus as a result of endochondral ossification. Fibroblastic cells in the granulation tissue on days 5 and 7 in Group F showed marked FGF-2 expression compared with Group R. Fibroblastic cells showed ongoing proliferation in granulation tissue in group F, as indicated by PCNA expression, which explained the relative granulation tissue increase in group F. There were major differences in early phase endogenous FGF-2 expression between these two fracture healing processes, due to different mechanical environments.

This paper posits that the 'student as customer' model has a negative impact upon the academic leadership which in turn is responsible for the erosion of objectivity in the assessment process in the higher education sector. The paper draws on the existing literature to explore the relationship between the student as customer model, academic leadership, and student assessment. The existing research emanating from the literature provides the basis from which the short comings of the student as customer model are exposed. From a practical perspective the arguments made in this paper provide the groundwork for possible future research into the adverse affects of the student as customer model on academic leadership and job satisfaction in the academic work force. The concern for quality may benefit from empirical investigation of the relationship between the student as customer model and quality learning and assessment outcomes in the higher education sector. The paper raises awareness of the faults with the present reliance on the student as customer model and the negative impact on both students and academic staff. The issues explored have the potential to influence the future directions of the higher education sector with regard to the social implications of their quest for quality educational outcomes. The paper addresses a gap in the literature in regard to use of the student as customer model and the subsequent adverse affect on academic leadership and assessment in higher education.

This position paper provides an overview of a proposed study that seeks to design and develop tools, methods and applications of urban informatics to promote an innovation culture and knowledge economy in regional Queensland. The National Broadband Network has the potential to leapfrog regional Queensland to join the knowledge economy, but effective applications and content strategies are required. The Edge is the Queensland Government’s Digital Culture Centre to engage young people in the technology/culture nexus. This position paper provides an overview of a proposed study that will set up Living Labs at The Edge and in a new precinct in rural Queensland (Goondiwindi) as sites to trial strategies and applications that engage people in entrepreneurial thinking, sustainability initiatives, and new creative practices across the urban and rural boundaries.

Formalised service innovation is a central tenet of enterprise systems lifecycle phases. Event driven process models extended with knowledge objects are found to be not useful in early lifecycle phases. When an upgrade is required, a map of the knowledge infrastructure is needed to better design further service innovation because functional maps no longer adequately describe the context adequately. By looking at formal changes to business processes as service innovations, and recognising the knowledge infrastructure inherent in services generally, changes driven through technology such as ES can be better understood with the application of frameworks such as B-KIDE.
Sensing properties of e-beam evaporated nanostructured pure and iron-doped tungsten oxide thin films

Gas sensing properties of nanostructured pure and iron-doped WO3 thin films are discussed. Electron beam evaporation technique has been used to obtain nanostructured thin films of WO3 and WO3:Fe with small grain size and porosity. Atomic force microscopy has been employed to study the microstructure. High sensitivity of both films towards NO2 is observed. Doping of the tungsten oxide film with Fe decreased the material resistance by a factor of about 30 when exposed to 5 ppm NO2. The high sensitivity is attributed to an improved microstructure of the films obtained through e-beam evaporation technique, and subsequent annealing at 300oC for 1 hour.

Purpose: Leadership styles are reviewed and reassessed given recent research that links destructive leadership behaviours exhibited by unscrupulous executives with traits commonly identified as indicators of corporate psychopathy. Method/approach: A review of the literature describing the various theories dealing with the nature of leadership styles and the rise of interest in corporate psychopathy and destructive leadership. Implications: This paper offers a psychological perspective for future research which provides both impetus and additional support for further analysis and exploration of such leadership styles in the business environment. One distinct advantage of this extrapolation is the articulation of insights into aspects of decision making by leaders, providing further insight into the formulation of leadership development programs in organisations and courses in business schools training future leaders.
