Unifying manufacturing simulation models using HLA

The increasing use of simulation in manufacturing has seen an increase in simulation models created using many simulation package. This use of different simulators can create simulation islands in a manufacturing factory, making it difficult to get a true simulated overview of the factory. At present, there are only a few cases where manufacturing simulations have been linked to enable multiple simulation models to run as one. This research expands upon these cases. For this paper the topic of discussion is the research in connecting different 'Commercial Off The Shelf' simulators together to allow flow of all information through the connected models using high level architecture.

Corporate governance, board responsibilities and financial performance : the National Bank of Australia

This paper examines board responsibilities and accountability by management and Board of Directors in relation to the National Australia Bank's (NABs) performance. The NAB, an international financial service provider within the top thirty most profitable banks in the world, is compared with the Australian major banks. The evidence suggests that NABs poor performance was consistent with a lack of accountability, poor corporate governance and board dysfunction associated with fraudulent currency trading and the subsequent AUD360 million foreign currency losses. The NAB's performance is investigated by utilising accounting-based measures of profitability and cost efficiency as proxies for performance. Following the foreign currency trading losses in 2004 the NAB under-performed the other major Australian banks in terms of profits, cost to income ratio and growth in assets. In terms of profitability and cost efficiency NAB had the lowest ROE and ROA with a 19.7% fall in net profit and the highest cost to income ratio of 5 7.4% of any of the five largest banks. This case study provides an Australian example of poor corporate governance and suggests that financial institutions and regulators can learn from the NAB's experience. Failure to have top-down accountability can have significant impact on over-all performance, profitability and reputation. In particular, it suggests that management and Boards need to review their risk management procedures and regulators need to be more pro-active in their prudential oversight of financial institutions.

Designing open-ended problems to challenge preservice teachers' views on mathematics and pedagogy

This study examines preservice elementary teachers' reported experiences of posing open-ended mathematics problems. Responses of 33 students in a mathematics teacher education course were analysed for the strategies participants used, what they learned and the challenges encountered from an opportunity to collect digital images and pose open-ended problems related to those images. Results indicate that preservice teachers reported a shift in the ways they viewed mathematics and how it might be taught. The school curriculum both constrained and provided possibilities for preservice teachers in noticing mathematics beyond the textbook and mathematics classroom. This study adds to our understanding of teaching as a learning practice and the art of posing mathematical problems as a significant aspect of that practice.

Group composition : influences of optimism and lack thereof

Lesson video and video-stimulated post-lesson interviews were used to study the role of optimism in collaborative problem solving in a Grade 5/6 classroom for the purpose of informing group composition. This study focuses on the activity of two students who differed on the personal characteristic 'optimistic orientation'. It examines how the presence or absence of an optimistic orientation to failures (Seligman, 1995) contributed to these students' interactions with their groups and opportunities for collaborative creation of new knowledge. One group collaborated to develop mathematical knowledge that was new to each group member and the other group did not. These findings raise questions about how to group students who are not yet optimistic to enable collaborative activity, and how to build optimism.

Educational organizations and gender in times of uncertainty

In this chapter I identify and elaborate, from a feminist perspective, upon the theoretical shifts and key concepts that inform sociological analyses of gender and educational organizations. Gender inequalities are embedded in the multi-dimensional structure of relationships between women and men, which, as the modern sociology of gender shows, operates at every level of experience, from economic arrangements, culture and the state to interpersonal relationships and individual emotions. (Connell, 2005: 1801) Even naming this a sociology of gender and organizations is problematic. Many sociologists consider gender as a key sociological concept, but not necessarily from a feminist perspective. Feminism is a multidisciplinary, transnational movement that 'focuses on the relationship between social movements, political action and social inequalities' (Arnot, 2002: 3) and on the everyday experiences of women and girls and how they translate into social and structural 'ruling relations' (Smith, 1988). Feminism takes on multiple trajectories and imperatives in different cultural contexts, although with familial resemblances, most particularly the shared objective of equality for women and girls. Education as a primary institution of individual and collective mobility and social change, but also social and economic reproduction, has long been a focus of feminist theory and activism. So a feminist sociology needs to address this complexity of feminist sociological 'encounters' with gender and organizations.

Does government linked companies (GLCs) perform better than non-GLCs? Evidence from Malaysian listed companies

The purpose of this paper is to examine the impact of an alternative ownership/control structure of corporate governance on firm performance. Specifically, we investigated the governance system of government linked companied (GLCs) in Malaysia. In this paper, we examine governance mechanism and firm performance of Malaysian GLCs and non-GLCs over a 11 year period from 1995 to 2005. We only select a sample of companies which are listed in Main Board. We chose a sample of 210 firms. We used Tobin’s Q which is an indicator of market performance is used as a proxy for company’s performances; meanwhile ROA is used to determine accounting performance. This paper is to determines whether after controlling firm specific characteristics such as corporate governance, agency cost, growth, risk and profitability, GLCs perform better than non-GLCs. Findings highlight that non-GLCs performance is better GLCs in term of corporate governance, and other firm specific characteristics. The relationship between ownership structure and firm performance has been issue of interest among academics, investors and policy makers as one of key issues in understanding the effectiveness of alternative governance systems where government ownership serves as a control mechanism.

Political connection and leverage: Some Malaysian evidence

This paper extends prior work on the linkage between politically connected (PCON) firms and capital structure in developing countries. Specifically, this paper focuses on the association between Malaysian PCON firms and leverage, and is motivated by the results of Fraser et al. (2006) who report a positive association between leverage and political patronage. Controlling for a potential misspecification in that paper, this study documents that a significant proportion (almost 12%) of the Malaysian PCON firms have negative equity, and builds on the previous paper by providing fresh evidence that market to book ratio is positively associated with leverage, and that borrowing PCON firms have significantly lower ROA compared to non-PCON firms. © 2012.
