A comparative study at the logical level of centralised and distributed recovery in clusters

Cluster systems are becoming more prevalent in today’s computer society and users are beginning to request that these systems be reliable. Currently, most clusters have been designed to provide high performance at the cost of providing little to no reliability. To combat this, this report looks at how a recovery facility, based on either a centralised or distributed approach could be implemented into a cluster that is supported by a check pointing facility. This recovery facility can then recover failed user processes by using checkpoints of the processes that have been taken during failure free execution.

FDI location at the subnational level: a study of EJVs in China

The location of FDI activities by MNEs is of interest to international business researchers, especially in light of the rapidly changing economic landscapes in many regions of the world. This paper adds to the literature on MNEs' location choices, focusing on how business characteristics are related to location, in a sample of 6430 foreign equity joint ventures (EJVs) in China during 1984–1996. The results show that the duration of the EJV agreement, the origin of the foreign investor, and the type of business activity are related to the location of the EJVs' business activities within China. Significant differences are noted in the locations of ventures in the manufacturing and service sectors, and there is evidence of an increasing preference for MNEs to locate their activities in China's large, metropolitan cities. These findings reflect the dynamic nature of government policies toward FDI in China and their impact on the location choices of MNEs.

Increasing the level of sustainability via off-site production : a study of the residential construction sector in China

Even though the use of off-site production in the construction process for residential buildings is seen as a viable means of increasing the level of sustainability with respects to its significant economic, environmental and social contributions, there have been very few studies to-date into off-site construction within the context of developing countries where the places have crucial demands for accommodations. Accordingly this research involves the rapidly growing developing nation, China, as a representative developing country with the objective to investigate the current status of off-site practices in the urban residential construction sector. This paper also examines the factors affecting demand for and potential barriers against a wider uptake of off-site technologies in China. The findings provide a rare insight into off-site construction in China’s housing industry and this information will be transferable to other developing countries. This study also contributes to a broader understanding about the off-site construction in developing from an international perspective.

Factors affecting perceived level of virtuality in hybrid construction project teams (HCPTs) : a qualitative study

Purpose-Deploying hybrid construction project teams (HCPTs) in which the common pattern of interactions is a blend of face-to-face and virtual communications has been increasingly gaining momentum in the construction context. Evidence has demonstrated that effectiveness of HCPTs is affected by a perceived level of virtuality, i.e. the perception of distance and boundaries between members where teams shift towards working virtually as opposed to purely collocated teams. This study aims to provide an integrated model of the factors affecting perceived virtuality in HCPTs, to address the conspicuous absence of studies on virtuality in the construction context. Design/methodology/approach-An a priori list of factors extracted from existing literature on virtuality was subjected to the scrutiny of 17 experts with experiences of working in HCPTs through semi-structured interviews. Nvivo 10 was deployed for analysing the interview transcripts. Findings-The fndings outline the factors affecting virtuality in HCPTs and map the patterns of their associations as an integrated model. This leads to discovering a number of novel factors, which exert moderating impacts upon perceived virtuality in HCPTs. Practical implications-The fndings assist managers and practitioners dealing with any form of HCPTs (including building information modelling-based networks and distributed design teams) in identifying the variables manipulating the effectiveness of their teams. This enables them of designing more effective team arrangements. Originality/value-As the frst empirical study on virtuality in the construction context, this paper contributes to the sphere by conceptualising and contextualising the concept of virtuality in the construction industry. The study presents a new typology for the factors affecting perceived virtuality by categorising them into predictors and moderators.

Association of family environment with children's television viewing and with low level of physical activity

Objective: This study examined associations between the family environment and children's television (TV) viewing and likelihood of being low-active.
Research Methods and Procedures: In 2001, children were recruited from 19 primary schools in Melbourne, Australia. Parents completed a questionnaire about their child's TV viewing and the family environment. Children also completed a questionnaire and wore an accelerometer for 8 days. Movement counts were used to identify low-active children (lowest quartile). Data were analyzed in May 2004.
Results: The sample consisted of 878 children (mean age = 11.5 0.6 yrs). Multiple logistic regression revealed that socioeconomic status [adjusted odds ratios (AOR) = 0.4 boys], frequency families watched TV together (AOR = 2.0 boys), mothers' (AOR = 1.8 boys; AOR = 2.5 girls) and fathers' (AOR = 2.6 boys; AOR = 2.8 girls) TV viewing, and rules prohibiting TV during mealtimes (AOR = 0.6 boys; AOR = 0.6 girls) related to children watching TV 2 h/d. Variables associated with low-level physical activity included self-reported enjoyment of Internet use (AOR = 1.7 boys) and preference for watching TV (AOR = 2.3 girls), perception that mother uses computer a lot (AOR = 1.9 boys) and likes using the computer (AOR = 0.6 girls), fathers' reported computer/electronic games use (AOR = 1.7 girls), frequency families used computer together (AOR = 0.4 girls), rules that TV viewing must be supervised (AOR = 1.9 boys; AOR = 0.6 girls), and having pay TV (AOR = 0.6 boys) and electronic games at home (AOR = 2.6 boys).
Discussion: These findings suggest that the relationships between the family environment and TV viewing and low-level activity are complex and that these behaviors are distinct.

The influence of locus of attribution, level of employee authority and employee concern on consumers postrecovery evaluations

This study employed a 3 x 2 x 2 full-factorial, between-subjects design experiment involving locus of attribution, concern, and the level of authority of the employee performing the recovery on consumers’ postcomplaint evaluations. The research, conducted in a restaurant context, involved a sample of 411 undergraduate students. Findings suggest that customers are less dissatisfied and more likely to revisit the restaurant when the location of the cause of the failure is internal (i.e., they are to blame). In addition, consumers are less likely to repurchase when the manager, as opposed to the waiter, is responsible for the service failure.

Internal audit - an Asia-Pacific profile and the level of compliance with internal auditing standards

Purpose – The purpose of this paper is to provide an overview of the profile of internal audit in five Asia-Pacific countries and investigate the usage and compliance with the Institute of Internal Auditors (IIA) International Standards for the Professional Practices of Internal Auditing (Standards) by organizations' internal audit activities (IAAs). This paper shows the differences between Australia, China, Japan, New Zealand and Taiwan. It also discusses part of the results of the Common Body of Knowledge 2006 global study conducted by the IIA.

Design/methodology/approach – The paper reports the results of a questionnaire survey sent to the global membership of the IIA in September 2006 on various aspects of internal audit practices.

Findings – The profile of internal audit differs amongst the countries with much older organizations exist in Australia, Japan and New Zealand. Respondents in New Zealand, Japan, Chinese Taiwan, China and Australia all report to have a reasonably high level of usage of Standards. However, Australia has the highest number of respondents who report that they are in full compliance of the Standards.

Originality/value – This is the first global study of internal auditors' compliance with the IIA Standards.

a7-Nicotinic acetylcholine receptors mediate an A71-42-induced increase in the level of acetylcholinesterase in primary cortical neurones

The β-amyloid protein (Aβ) is the major protein component of amyloid plaques found in the Alzheimer brain. Although there is a loss of acetylcholinesterase (AChE) from both cholinergic and non-cholinergic neurones in the brain of Alzheimer patients, the level of AChE is increased around amyloid plaques. Previous studies using P19 cells in culture and transgenic mice which overexpress human Aβ have suggested that this increase may be due to a direct action of Aβ on AChE expression in cells adjacent to amyloid plaques. The aim of the present study was to examine the mechanism by which Aβ increases levels of AChE in primary cortical neurones. Aβ₁₋₄₂ was more potent than Aβ₁₋₄₀ in its ability to increase AChE in primary cortical neurones. The increase in AChE was unrelated to the toxic effects of the Aβ peptides. The effect of Aβ₁₋₄₂ on AChE was blocked by inhibitors of α7 nicotinic acetylcholine receptors (α7 nAChRs) as well as by inhibitors of L- or N-type voltage-dependent calcium channels (VDCCs), whereas agonists of α7 nAChRs (choline, nicotine) increased the level of AChE. The results demonstrate that the effect of Aβ₁₋₄₂ on AChE is due to an agonist effect of Aβ₁₋₄₂ on the α7 nAChR.

The level of representative underwriting and the underwriting costs of REIT SEOs

Purpose – The purpose of this paper is to investigate factors influencing the underwriting discount for US Real Estate Investment Trust (REIT) Seasoned Equity Offerings (SEOs).

Design/methodology/approach – The study provides new evidence on determinants of underwriting discounts with a comprehensive dataset of 783 US REIT SEOs from 1996 until June 2010. Ordinary least squares regressions are performed to estimate the effect of the level of representative underwriting along with other potential factors on underwriting discounts.

Findings – The study complements the well-documented notion of the economies of scale in SEO underwriting discounts. The equally (value) weighted underwriting discounts averaged 4.21 per cent (4.10 per cent) with a declining trend over time. The findings of this study show the statistically and economically significant negative effect of the level of representative underwriting on the underwriting discounts, as well as the significance of the structure of underwriting syndicate in determining the underwriting discounts. The findings suggest that issuers can minimize the costs of raising secondary equity capital by optimally allocating the underwriting business among the underwriters.

Originality/value – This paper adds to the international REIT SEO literature by exploring new evidence behind underwriting discounts. The study includes data before and after the REIT Modernization Act 1999 and during the recent global financial crisis period.

Effects of study design and allocation on participant behaviour-ESDA: study protocol for a randomized controlled trial

BACKGROUND: What study participants think about the nature of a study has been hypothesised to affect subsequent behaviour and to potentially bias study findings. In this trial we examine the impact of awareness of study design and allocation on participant drinking behaviour. METHODS/DESIGN: A three-arm parallel group randomised controlled trial design will be used. All recruitment, screening, randomisation, and follow-up will be conducted on-line among university students. Participants who indicate a hazardous level of alcohol consumption will be randomly assigned to one of three groups. Group A will be informed their drinking will be assessed at baseline and again in one month (as in a cohort study design). Group B will be told the study is an intervention trial and they are in the control group. Group C will be told the study is an intervention trial and they are in the intervention group. All will receive exactly the same brief educational material to read. After one month, alcohol intake for the past 4 weeks will be assessed. DISCUSSION: The experimental manipulations address subtle and previously unexplored ways in which participant behaviour may be unwittingly influenced by standard practice in trials. Given the necessity of relying on self-reported outcome, it will not be possible to distinguish true behaviour change from reporting artefact. This does not matter in the present study, as any effects of awareness of study design or allocation involve bias that is not well understood. There has been little research on awareness effects, and our outcomes will provide an indication of the possible value of further studies of this type and inform hypothesis generation. TRIAL REGISTRATION: Australia and New Zealand Clinical Trials Register (ANZCTR): ACTRN12610000846022.

Learning approaches: examination type, discipline of study, and gender

A sample of 248 Australian university students participated in a study that investigated the influence of assessment type and discipline of study on students' learning approaches. Participants (93 psychology and 155 business students) responded to the Study Process Questionnaire in a context of preparation for a hypothetical examination. The hypothetical examination is in either a multiple-choice or an essay format. Results indicated that assessment type had no significant influence on how students approach their learning, while discipline did have significant influence on student learning.

Students` perceptions of study modes

This paper reports on a survey of how Australian undergraduate students perceive the benefits of broad study modes: face-to-face classes, web-based study, and print-based study. Two benefit types were identified through factor analysis: engagement and functionality. Respondents rated face-to-face classes highest on engagement and print-based study highest on functionality. However, they distinguished only marginally between the engagement and functionality benefits of print-based and web-based study. Two variables associated with differences in students' perceptions of study modes were attendance mode and student tenure. The findings raise questions about the learning and marketing rationales for offering web-based delivery of educational programmes at the expense of both the traditional face-to-face experience and the traditional “distance” experience in Australia using print materials.

A technology of study applied in marketing education and supported by self-determination theory

The aim of this study is to assess whether universities are meeting the needs of marketing students in their specific university function of providing knowledge and knowledge processes. This viewpoint is not meant to overlook the university role as a civilizing agent in a constant search for truth (McKenna 2001), but the focus for this study (based as it is in a Faculty of Business and Law) is toward graduates entering the corporate world. Therefore, graduates with suitable discipline knowledge and reasoning skills, in this context, must be able to meet the needs of the corporate marketing sector. Extending this backward to the role of the university, this study is by default seeking to establish if universities are meeting the needs of the corporate sector. A comparison is made between marketing classes using a specific technology of study called an autarchic system, and those classes not using this method. As part of this analysis the study investigates the application of self-determination theory and psychological needs satisfaction. The basic needs scale, comprising of two constructs; Control and Caring was adapted and used to evaluate students' perception of subjects using autarchic study system and those not utilising this methodology.
