Toward an operating system that supports parallel processing on nondedicated clusters

Present operating systems are not built to support parallel computing on clusters - they do not provide services to manage parallelism, i.e., to manage parallel processes and cluster resources. They do not provide support for both programming paradigms, Message Passing (MP) or Distributed Shared Memory (DSM). Due to poor operating systems, users must deal with computers of a cluster rather than to see this cluster as a single powerful computer. There is a need for cluster operating systems. We claim that it is possible to develop a cluster operating system that is able to efficiently manage parallelism, support MP and DSM and offer transparency. To substantiate this claim the first version of a cluster operating system managing parallelism and offering transparency, called GENESIS, has been developed.

Where in the world is room N101? Engaging with first year education students' experiences of transition

National reports on students’ experiences in their first year of tertiary study suggest that many students, particularly those coming directly from  secondary schools, find the transition into university life particularly difficult. These reports suggest that while many students find the experience to be a challenging hurdle others feel disengaged and unconnected to academic life. Reports also note that many students enter university with the expectation that their university experience should 'fit into their lives' rather than vice-versa.

Additionally, research indicates that successful transitional experiences for undergraduate students are critical in promoting effective learning habits, positive attitudes and openness to new knowledge. Establishing positive practices in the early days of the undergraduate course can enable students to utilise these experiences and knowledge as a part of their life-long professional habits. However, in order for this to occur, connections must be made, and relationships built, between students and their new peer groups and with the wider academic community. Connections must also be made between students' prior experiences and their new knowledge.

In light of the findings of recent research and reports, Deakin University has instituted a First Year Initiative to assist students in their transitions. Alongside and complementary to this, the Faculty of Education has developed a new three year Education Studies Major program which began this year.

In this paper, we discuss the ways in which the first two units of this new educational program aim to address some of the issues that students face when making the transition into university life. We see the implementation of the first two units as a 'pilot study' and while at this stage, evaluation of these units is only beginning, here we will consider some of the pedagogical strategies, resources, organisational structures and 'grounded' experiences that are being trialled as means to help students make the connections and take the first successful steps in their journey to becoming professional educators. Ways in which these new approaches aim to build important relationships between students, with staff and, as well, help them connect their prior experiences with new knowledge, will be considered in light of the literature on first year student transitions.

Operating a studio within a research culture: the urban heart surgery design research forum

The question of whether or not design can be considered research has perplexed schools of architecture ever since they were first introduced into universities. It was at the center of the Oxbridge union debates in the early 1900s. It formed one of the corner stones of the Oxford conference on education organized by the RIBA in 1958 (Martin 1958) and came under scrutiny again in the UK with the introduction of the Research Assessment Exercise (RAE) in 1992. While the arguments both for and against are considerable1, “in order to understand the questions and the possibilities of architectural research and to respond to the difficulties that confront us now, we have to have a model which acknowledges what schools of architecture really are, and could be, and then work with that” 2.
Drawing on professionally oriented research models, such as qualitative ‘clinical research’, from Medicine and the Health Sciences - where the processes of exploration, observation, investigation, recording and communication are conducted in-situ by the ‘practitioner-as-researcher’ 3 - the following paper outlines an initiative introduced in 1999, referred to as the ‘Urban Heart Surgery’ 4. The program actively integrates students entering their second degree program into a studio based design research culture and allows them to engage in critical discourse by working on high profile strategic design projects in three areas significant to Victoria’s future growth: Metropolitan Urbanism, Urbanism on the Periphery, and Regional Urbanism.
With a growing core of industrial and community based partnerships, including: four regional councils (Bendigo, Ballarat, Geelong and Warrnambool) and three metropolitan municipalities (Melbourne City, Port Phillip and Wyndham), the forum actively facilitates a graduate/practice research agenda through the ARC linkage grant program.

A scale-model room as a practical teaching experiment

A practical experiment is described which was used to help university students increase their understanding of the effect of construction methods and window design on passive solar heating and electrical heating. A number of one tenth scale model rooms were constructed by students and sited out-of-doors in the late autumn. The models were fabricated to mimic available commercial construction techniques with careful consideration being given to window size and placement for solar access. Each model had a thermostatically controlled electric heating element. The temperatures and electricity use of the models were recorded using data-loggers over a two week period. The performances of the models based on energy consumption and internal temperature were compared with each other and with predictions based upon thermal mass and R-values. Examples of questions used by students to facilitate this process are included. The effect of scaling on thermal properties was analysed using Buckingham’s p-theorem.

Cluster operating system support for parallel autonomic computing

The aim of this paper is to show a general design of autonomic elements and initial implementation of a cluster operating system that moves parallel processing on clusters to the computing mainstream using the autonomic computing vision. The significance of this solution is as follows. Autonomic Computing was identified by IBM as one of computing's Grand Challenges. The human body was used to illustrate an Autonomic Computing system that possesses self-knowledge, self-configuration, self optimization, self-healing, and self-protection, knowledge of its environment and user friendliness properties. One of the areas that could benefit from the comprehensive approach created by the autonomic computing vision is parallel processing on non-dedicated clusters. Many researchers and research groups have responded positively to the challenge by initiating research around one or two of the characteristics identified by IBM as the requirements for autonomic computing. We demonstrate here that it is possible to satisfy all Autonomic Computing characteristics.

Room-temperature insertion of elemental tellurium into the Cspł-Br and -I bonds of α-bromo-and α-iodopinacolone

Pinacolyltellurium(IV) dihalides, (t-BuCOCH₂)₂TeX₂ (X ) Br (1b), I (1c)) and Ar(t-BuCOCH₂)TeCl₂ (Ar == 1-C₁₀H₇ (Np) (2a), 2,4,6-Me₃C₆H₂ (Mes) (3a)), are readily prepared at room temperature by the oxidative insertion of elemental tellurium into the C_sp³-Br or -I bond of the α-halopinacolone and by the reaction of ArTeCl₃ with the pinacolone t-BuCOCH₃. The bromides Np(t-BuCOCH₂)TeBr₂ (2b) and Mes(t-BuCOCH₂)TeBr₂ (3b) can be prepared by the addition of bromine to the telluride Ar(t-BuCOCH₂)-Te or of α-bromopinacolone to ArTeBr. Variable-temperature ¹H and ¹³C NMR of the separate signals for the o-Me groups in 3a,b indicate a very high barrier to rotation about the Te-C(aryl) bond. Crystal diffraction data for 1c, 2a-c, and 3b show that intramolecular 1,4-Te …O(C) secondary bonding interactions (SBIs) are retained even in the presence of bulky aryl groups and intermolecular Te …X SBIs are subject to electronic population and steric congestion around the Te(IV) center in the solid state.

Overseas Chinese as expatriate managers in China: is their recruitment a solution to cross-cultural management problems for multinationals operating in China?

This paper examines the issue of diversity in Chinese identity and how it impacts on the operations of multinationals in China who recruit Overseas Chinese to handle cross-cultural issues. China’s rapid economic development and entry into the World Trade Organization in 2001 made her a formidable player in the global economy and direct foreign investment surged. Yet it is acknowledged that for the foreign investor in China, cross-cultural issues create difficulty at every level, from the interpersonal level relating to communication and negotiation, to the organizational level relating to decision making, human resource management practices, corporate legal institutions and liaison with government institutions. Western multinationals have considered the advantages of posting Overseas Chinese from Southeast Asian countries, Taiwan and Hong Kong to their China operations as a solution to cross-cultural management issues. But has this policy been successful? In terms of language expertise this would seem to be a good strategy, yet organizational case material contradicts this in reality. Overseas Chinese, while sharing some elements of Chinese culture with mainland Chinese, the Confucian heritage and other aspects such as language and diet, nevertheless have different world views and values and behave differently from mainland Chinese in areas critical to business management. As a survival strategy, Overseas Chinese have often developed dual identities which operate simultaneously. For political and historical reasons, many of them have had to adapt to the local culture of their country of citizenship or even hide their own ethnicity in order to survive. On the other hand, the mainland Chinese are different in that their behaviour has only had to be Chinese, but overlaid with this has been the experience of participating in a communist political environment for decades, which has left its mark on mainland Chinese culture. On the basis of their different historical experiences, in the current business environment in China, cultural confusion, difficulty and conflict may occur for the Overseas Chinese.

This paper focuses attention on the subtle cultural differences between the Overseas Chinese and mainland Chinese in an organizational context. This problem has yet to be researched in depth within international business and international management studies. It provides evidence that Overseas Chinese are not often favoured by the local Chinese. It gives insights on how to manage the local Chinese for foreign multinationals operating in China.

Interventions for educating children who have attended the emergency room for asthma (Review)

Background: Asthma is one of the most common reasons for paediatric admissions to hospital, with substantial cost to the community. There is some evidence to suggest that many hospital admissions could be prevented with effective education about asthma and its management.
Objectives: To conduct a systematic review of the literature in order to identify whether asthma education leads to improved health outcomes in children who have attended the emergency department for asthma.
Search strategy: We searched the Cochrane Airways Group trials register, including MEDLINE, EMBASE, and CINAHL databases, and reference lists of trials and review articles.
Selection criteria: Randomised controlled trials or controlled clinical trials of asthma education for children who had attended the emergency department for asthma, with or without hospitalisation, within the previous 12 months. Data collection and analysis:Two reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information.
Main results: Eight trials involving 1407 patients were included, in all the education was provided by nurses or researchers. Compared to control (usual care or lower intensity education) education did not reduce subsequent emergency department (ED) visits [4 trials; relative risk (RR)= 0.87, 95% confidence interval (CI) 0.37 to 2.08], hospital admissions [5 trials; RR=0.74, 95% CI 0.38 to 1.46] and unscheduled doctor visits [5 trials; RR= 0.74, 95% CI 0.49 to 1.12). Each analysis showed evidence of heterogeneity among the studies (P<0.01). Subgroup analyses by the overall difference in scale of intervention between treatment and control groups (comprehensive programme versus information only) or the timing of the intervention/recruitment (early versus delayed) gave similar results to the main analysis and still revealed significant heterogeneity between trials. Authors' conclusions: On the basis of the published trials, there is no firm evidence to support the use of asthma education for children who have attended the emergency department for asthma as a means of reducing subsequent ED visits, hospital admissions or unscheduled doctor visits. Some trials appeared to show clear evidence of benefit, but reasons for differences between these and the negative studies is not clear. More research is required.

Simulation of the solar adsorption refrigeration operating at near atmospheric pressure

To solve the leaking problem faced by current vacuum adsorption refrigeration systems, the authors have carried out a series of studies on the concept of raising the system's pressure to around atmospheric pressure with an inert gas (eg. Helium) as the pressure-adjusting agent. This paper presents the simulation of the performance oj the activated carbon-methanol adsorption refrigeration operating at near atmospheric pressure powered by solar energy. This simulation can be refereed in the prototype design.

Ethical structures and processes of corporations operating in Australia, Canada and Sweden : A longitudinal and cross-cultural study

Based on the ‘Partnership Model of Corporate Ethics’ (Wood, 2002), this study examines the ethical structures and processes that are put in place by organizations to enhance the ethical business behavior of staff. The study examines the use of these structures and processes amongst the top companies in the three countries of Australia, Canada, and Sweden over two time periods (2001–2002 and 2005–2006). Subsequently, a combined comparative and longitudinal approach is applied in the study, which we contend is a unique approach in the area of business ethics. The findings of the study indicate that corporations operating in Sweden have utilized ethical structures and processes differently than their Canadian and/or Australian counterparts, and that in each culture the way that companies fashion their approach to business ethics appears congruent with their national cultural values. There does, however, appear to be a convergence of views within the organizations of each culture, as the Swedish companies appear to have been more influenced in 2005–2006 by an Anglo-Saxon business paradigm than they have been in the past.

States, markets and communities : is there room for educational leadership?

This paper attempts a comparative analysis of classification and framing relationships as they are exemplified in the four papers presented in this Special Issue. In particular, it interrogates Bernstein's assertion that education is simply a relay for power relations external to it and examines approaches to educational leadership and administration that follow from such analysis. It is concluded that in different times and places power relationships external to education are often complex and contested, producing a variety of relays and attempts at classification and framing that serve differing interests and are articulated through policies containing significant internal contradictions. In such circumstances contingency and immediate local influence may affect the practice of educational leadership as well as offering scope for subversion, resistance, simulated consent and collective action. The possibility of a public pedagogy through which such complexities could be articulated is raised and its importance to the practice of educational leadership affirmed.
