Construction capital productivity measurement using a data envelopment analysis

During the past few decades, the construction industry has experienced a series of changes including the innovation of construction technologies and the enhancement of management strategies. These improvements should have had a considerable effect on industrial efficiency and productivity performance, but research is needed to address whether the capital productivity levels of the construction industry have in fact shown such a huge improvement. This paper aims to develop an analysis procedure to measure capital productivity changes and to reasonably quantify factors affecting productivity levels in the construction industry. Based on the data envelopment analysis method, this research has developed a novel model measuring capital productivity and has applied it to the Australian construction industry. The numerical results indicate that the average annual capital productivity levels of the construction industry are slowly growing in all the Australian states and territories except for Queensland and Western Australia. In addition, construction technologies are shown to have a close relationship with the changes in capital productivity according to the temporal-spatial comparisons of productivity indices. The research findings are expected to be beneficial for making policy and strategic decisions to improve the capital productivity performance.

House price bubble estimations in Australia's capital cities with market fundamentals

This paper investigates the existence of house price bubbles in Australia's eight capital cities in recent years by using quantitative analyses including Johansen cointegration test, Granger causality test, impulse response and Chow forecast test. While interactions between house prices and market fundamentals are discussed in long-run and causal estimations, shocks from the market fundamentals to house prices are investigated in generalized impulse response analyses. Findings from estimating house price bubbles for eight capital cities suggest that there was an obvious house price bubble in Perth, while a slight house price bubble occurred in Sydney. In contrast, house prices in Adelaide and Darwin can be explained very well by market fundamentals, while house prices in Melbourne, Brisbane, Hobart and Canberra were undervalued in the study period.

Plagiarism : proactive prevention instead of reactive punishment

Purpose - This study investigated whether providing university students with extra feedback regarding their referencing improves their referencing confidence and reduces their propensity to plagiarise. The study also sought to increase our understanding of what factors underlie student plagiarism.

Design/methodology/approach - Undergraduate and post-graduate accounting students were surveyed regarding their experience when completing a formative essay designed to give feedback on their referencing ability. All students in one undergraduate and one postgraduate accounting course were invited to participate in a post-assessment, electronically administered survey consisting of sixteen question.

Findings - The results indicate that a considerable number of the students perceived the formative assessment to be of benefit with respect to improving their referencing confidence. A significant proportion of the students indicated that their understanding of what constitutes plagiarism and their confidence in avoiding plagiarism improved as a result of the assessment and its associated feedback.

Research limitations/implications - This study supports the provision of assessment designed to assist students with improving their ability to both recognise and avoid plagiarism in their written work. However, this research has not investigated whether these types of exercises lead to an actual reduction in the incidence of plagiarism in tertiary student cohorts. This is an area for future research.

Erotic capital, popular pedagogy, and healthy adolescent female sexuality

The sexualization of the female body in contemporary media has created considerable anxiety about its impact on girls. Much of the resulting research focuses on the influence of visual media on body image and the flow-on effects for girls' health. Rather less attention is paid to the pedagogical role of popular romance fiction in teaching girls about their sexuality. Given the pronounced increase in eroticized fiction for girls over the past decade, this is a significant oversight. This article applies Hakim's (2010) concept of erotic capital to two chick lit novels for girls. The elements of erotic capital—assets additional to economic, cultural and social capital—are used to explore the lessons these novels teach about girl sexual subjectivities and sociality in a sexualized culture.

Case study of e-learning experts in Malaysia : impact of social capital and social networks

This paper examines the experiences of selected academics pioneering e-learning in Malaysian tertiary institutions. It begins with an overview of the broad factors shaping the Malaysian educational environment and then proceeds to examine the experience of individual teachers and e-learning programs. It takes an in-depth qualitative approach to engaging with this case study material drawing heavily on semi-structured interviews with key actors.
Conversations with several respondents suggested that the social networks of mentor relations found in the Malaysian case studies might be aptly described as ‘bamboo networks’. Bamboo, which happens to be plentiful in the Malaysian peninsula where these case studies are based, spreads from clump to clump through a series of underground connections involving a mature clump of bamboo sending out a subterranean runner, often over very long distances that then emerge into the open as a new bamboo clump.
All of those interviewed reported that they have found it difficult to find a support base in their first years of pioneering online developments. Consequently, they tended to fall back on their peer networks linked to the institutions at which they had studied. Prominent individuals championing e-learning in the institutions where they teach tend to form small groups for information sharing and networking. They do look to their management for tacit ‘permission’ rather than direct encouragement. Consequently, the active promotion of e-learning in Malaysia can be described as being ‘middle-down’ rather than ‘top-down’ in nature. That is to say, it is mid-level teachers that inspire those below them to join in the development of e-learning programs. They are internally driven and strongly motivated. In time, their activity should produce new generations of locally developed e-learning experts but this has yet to take place in a substantial fashion. This study shows that both men and women ‘academic guanxi’, or peer networks, play a key role in the adoption of online technologies. Key early adopters become change-agents by inspiring a small network of their peers and via their guanxi networks. It was also discovered that motivation is not simply an individual matter but is also about groups and peer networks or communities of exchange and encouragement. In the development of e-learning in Malaysia, there is very little activity that is not linked to small clusters of developers who are tied into wider networks through personal contacts.
Like clumping bamboo, whilst the local clusters tend to be easily seen, the longer-range ‘subterranean’ personal connections are generally not nearly so immediately obvious. These connections are often the product of previous mentoring relationships, including the relationships between influential teachers and their former postgraduate students. These relationships tend to work like bamboo runners: they run off in multiple directions, subterranean and unseen and then throw up new clumps that then send out fresh runners of their own.

Reading house prices in Australian capital cities

House prices in the Australian capital cities have been increasing over the last two decades. An over 10% average annual increase arises in the capital cities. In Melbourne, Brisbane and Perth, the house prices increased by more than 15% annually, while the house prices in Darwin increased by even higher at about 21%. It is surprising that, after a decrease in 2008, the house prices in the Australian capital cities show a strong recovery in their last financial year’s increase. How to read the house prices in cities across a country has been an issue of public interest since the late 1980s. Various models were developed to investigate the behaviours of house prices over time or space. A spatio-temporal model, introduced in recent literature, appears advantages in accounting for the spatial effects on house prices. However, the decay of temporal effects and temporal dynamics of the spatial effects cannot be addressed by the spatio-temporal model. This research will suggest a three-part decomposition framework in reading urban house price behaviours. Based on the spatio-temporal model, a time weighted spatio-temporal model is developed. This new model assumes that an urban house price movement should be decomposed by urban characterised factors, time correlated factors and space correlated factors. A time weighted is constructed to capture the temporal decay of the time correlated effects, while a spatio-temporal weight is constructed to account for the timevaried space correlated effects. The house prices of the Australian capital cities are investigated by using the time weighted spatio-temporal model. The empirical findings suggest that the housing markets should be clustered by their geographic locations. The rest parts of this paper are organised as follows. The following section will present a principle for reading urban house prices. The next section will outline the methodologies modelling the time weighted spatio-temporal model. The subsequent section will report the relative data and empirical results, while the final section will generate the conclusions.

Clarifying the link between social capital and MSME innovation performance : the role of absorptive capacity

A conceptual framework is proposed in this article showing how the social capital of a community shapes the innovation performance of micro, small and medium enterprises (MSMEs) through the exercise of absorptive capacity as the mediating phenomenon between the two. Its significance stems from the unprecedented effort of explaining how community social capital matters in the innovation performance of MSMEs, a departure from previous studies which typically examined market-related or hierarchical social capital in the form of formal networks and directly linking them to firm innovation without due regard to knowledge management within the firm as an antecedent of organizational innovation. The aim is to stimulate further thinking and empirical research on the subject of social capital of a community in an MSME and/or entrepreneurial context.

Neighbourhood environments and children's social capital : investigating the pattern of relationships

The main purpose of this work was to investigate the pattern of relationships among three constructs: neighbourhood socio-physical environment, children's social interactions and their social capital. This work was designed as a two-phase mixed-methods research. Phase I included several qualitative studies to develop a scale of neighbourhood socio-physical environment, a scale of children's social interactions and a scale of children's social capital. Phase II was a cross-national survey that used these three scales to collect information from high school students in Beijing and Sydney. The main finding of this work was that there were strong and significant correlations among the three constructs. Children's assessment of their neighbourhood socio-physical environment was positively correlated with their social interactions and social capital, which indicated that children who lived in better neighbourhoods had more social interactions and larger volumes of social capital. Strong positive relationship was also found between children's social interactions and social capital, which implied that better-connected children interacted with their friends more.
