New ways to educate Asia-Pacific entrepreneurs

Asia-Pacific countries have huge numbers of young entrepreneurs. Yet the state of entrepreneurship education in this region has yet to come to grips with their needs. Elsewhere in the world, the growth and development in the curricula, textbooks, Websites and degree programs devoted to raising the level of enterprise and new venture creation has been remarkable.

The researcher undertook field study to examine best-practice models of enterprise education. He then carried out a content analysis of leading entrepreneurship textbooks to examine their applicability to the Asia-Pacific circumstance. Working with Thomson Learning Australia, he acquired the rights to re-write one leading textbook and entirely “asianised” it. He also produced a highly interactive Website to attract Internetnet savvy young entrepreneurs and students in the countries of the Asia-Pacific region.

The paper offers generalization that may prove helpful to educationalists and government policy planners about how to increase the supply of young people who launch their own businesses and social enterprises. The goal of this paper is to help universities in our region move toward launching entrepreneurship education in a relevant and interesting way.

Complexity of data rich architectural environments

This research focused on developing a detailed understanding of current organisational interactions and information flows in a construction industry based field study of a refurbishment projects of a 100 year old warehouse building. From this, conclusions are then drawn regarding the application of information and communication technologies (ICT) to the industry.

Self in architecture

Presents the hypothesis that within the making of architecture a buried, perhaps unconscious, aspect of self finds its way into the architectural project. Field study interviews were conducted with architects working in practice.

The use of control systems in new product development innovation : advancing the 'help or hinder' debate

New Product Development (NPD) innovation is a critical activity in the current economic environment. In order to manage their NPD innovation projects, firms use Management Controls Systems (MCS). However, the effect that these systems have on NPD innovation is not clear. One stream of research suggests that MCS help NPD innovation while another stream suggests MCS hinder NPD innovation. Past research has shown that the role and style of MCS used may offer explanations on why MCS can both help and hinder NPD innovation. This paper adds another explanation by examining the relationship between three models (divisional, activity/decision and conversion/response) of a commonly used MCS, known as the Stage-Gate Process1 in the NPD innovation literature, and three types of NPD innovation projects (incremental, semi-radical and radical). The insights from an ethnomethodology informed field study are used to understand how and why the firms may use a different MCS (Stage-Gate Process models) for different NPD innovation project types.

Parental and home influences on adolescents' TV viewing : a mediation analysis

Objective. To explore the association between home environmental variables and television (TV) time, and the mediating pathways underlying this association.

Methods. The current study used data from the longitudinal ENDORSE study. Self-reported data was available for 1 265 adolescents (mean age of 12–15 years at baseline) on home environment (availability of a TV in the bedroom, perceived parental modelling, family rules), potential mediators (intention, attitude, perceived behavioural control, subjective norm towards TV viewing) and TV viewing time. Mediation analyses were conducted using General Estimating Equations and mediation effects were calculated as the product-of-coefficients.

Results. Significant overall positive associations were found for the presence of a TV in the bedroom and parental modelling with self-reported TV viewing. Controlling family rules showed an inverse association with reported TV time. Similarly, parental modelling and a TV in the bedroom were significantly positively associated with the Theory of Planned Behaviour variables and habit strength, while family rules showed an inverse association with these potential mediators. In turn, most potential mediators were positively associated with TV viewing. Intention, attitude and habit strength were the strongest mediators in all three associations explaining more than 55% of the overall association. Habit strength alone explained 38.2%–58.0% of the overall associations.

Conclusions. Home and family environmental predictors of TV time among adolescents may be strongly mediated by habit strength and other personal factors. Future intervention studies should explore if changes in home and family environments indeed lead to reductions in TV time through these mediators.

Balancing comfort expectations and greenhouse gas emissions, thermal comfort in office buildings in a changing climate

According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), the construction sector has the greatest potential for climate change mitigation. This work investigates the potential for climate change mitigation in naturally ventilated and mixed mode office buildings, by evaluating the range of influence of building design and occupants on greenhouse gas emissions as well as thermal and visual comfort.

Thermal comfort is evaluated according to the EN 15251 adaptive thermal comfort model, visual comfort is based on daylight autonomy and view. Parametric studies have been conducted based on building simulation for the climate of Athens, Greece. Input data are based on a literature review, and on results from a field study conducted among office occupants and architects in Athens.

The results show that the influence of occupants on greenhouse gas emissions is larger than the influence of building design. Energy saving office equipment, as well as active use of building controls for shading and lighting by occupants are crucial parameters regarding the reduction of CO2 emissions. In mixed mode buildings, the coefficient of performance of the cooling system is an important parameter as well. Regarding thermal and visual comfort, the influence of building design is predominant. A green building, well protected against heat from the sun and able to balance solar and internal heat gains, provides higher comfort levels and is less affected by the influence of occupants. In mixed mode buildings, building design is the predominant influence on the magnitude of cooling loads. A hot summer including heat waves can significantly reduce thermal comfort and increase the resulting greenhouse gas emissions. Green buildings are least affected by these influences.

The EN 15251 adaptive thermal comfort model provides a thermal comfort evaluation method valid throughout Europe. However, for the Mediterranean climate of Athens, Greece, most of the configurations investigated within this study do not meet the requirements according to this model. EN 15251 refers to an adaptive thermal comfort model for naturally ventilated and to a static model for mechanically ventilated buildings. For mixed mode buildings, the static model is recommended, but literature indicates that occupants in those buildings might be more tolerant towards higher temperatures. The hypothetical application of the EN 15251 adaptive thermal comfort model in mixed mode offices, as investigated in this study, shows potential for greenhouse gas emission savings. However, this influence is small compared to that of building design and occupants. Conclusions are drawn regarding the categorisation and exceeding criteria according to EN 15251 adaptive thermal comfort model for offices in a Mediterranean climate.

The results of this work show, that not only green buildings, but also green occupants can significantly contribute to the mitigation of the climate change. Mechanisms of the real estate market as well as the lifestyle of occupants are important influences in this context. Sustainability therefore refers to finding the right balance between occupant’s comfort expectations and resulting greenhouse gas emissions for a specific building, rather than optimisation of single parameters

Retrodicting patch use by foraging swans in a heterogeneous environment using a set of functional responses

Effective conservation of important bird areas requires insight in the number of birds an area can support, and how this carrying capacity changes with habitat modifications. When food depletion is the dominant mechanism of competition, it should in principle be possible to calculate the total time foragers can spend per patch from their functional response (intake rate as a function of food density). However, in the field there are likely to be factors modulating the functional response. In this study previously published results of experiments on captive Bewick's swans were used to obtain functional responses of swans digging for tubers of Fennel pondweed on different foraging substrates: sandy and clayey sediment, and in shallow and deep water. In a field study, four 250×250 m sections belonging to different types (sandy–shallow, clayey–shallow, sandy–deep and clayey–deep) were delineated. Here tubers were sampled with sediment corers in three years, both before and after swan exploitation in autumn, and swans were observed and mapped from a hide in two of these years. Giving-up tuber biomass densities varied among sections. Substitution of these giving-up densities in the derived patch-type-specific functional responses yielded the quitting net energy intake rates in the four sections. As expected from the marginal value theorem, the quitting net energy intake rates did not vary among sections. Moreover, the observed foraging pressure (total foraging time per area) per patch type was in quantitative agreement with the integrated functional responses. These results suggest that in spatially heterogeneous environments, patch exploitation by foragers can be predicted from their functional responses after accounting for foraging substrate.

Power, influence and intranet implementation : a safari of South African organizations

Intranets hold great promise as ``organizational Internets'' to allow information sharing and collaboration across departments, functions and different information systems within an organization. Yet not much is known about how to implement intranets. We adapt a taxonomy based on institutional theory and distinguish six broad diffusion drivers that might be considered to sustain the implementation process. An exploratory field study of four intranet implementations was conducted to analyze which drivers were used and the results that were yielded. We draw several conclusions. First, all six drivers were deployed in the analyzed cases. Second, the choice of drivers varied with the level of the intranet (corporate or unit), the implementation stage, and existing organizational practices and contingencies. Third, it seems that the critical drivers are knowledge building, subsidy and mobilization in the early stages of implementation. In the later stages knowledge deployment, subsidy and innovation directives were most commonly used.

Green bodies : training environmental educators

In this paper, we examine the “greening” of Outdoor & Environmental Education (OEE) students at an Australian regional university through three lenses: temporal, spatial & material. We are inspired by Grosz’ claim that “bodies are always understood within a spatial & temporal context, & space & time remain conceivable only insofar as corporeality provides the basis for our perception & representation of them” (1995, p. 84). As suggested by Grosz, these lenses are not discrete and, in the course of the paper, their intersections & reciprocity become apparent. We draw on interview responses & observations from a longitudinal cohort study undertaken by Preston in an attempt to trace the regulation and practice of “green” “outdoor Ed” subjectivities in the context of the materialities, time & spaces of this specific course.

Changes in body mass index and health related quality of life from childhood to adolescence

Objective . To determine longitudinal relationships between body mass index (BMI) and health-related quality of life (HRQoL) in an adolescent population sample.
Design. Data collected in 2000 and 2005 within the Health of Young Victorians longitudinal cohort study.
Setting. Originally a community sample of elementary school students in Victoria, Australia. Follow-up occurred in either secondary schools or individuals homes.
Participants. Cohort recruited in 1997 via a random sampling design from Victorian elementary schools. Originally comprising 1 943 children, 1 569 (80.8%) participated in 2000 (wave 2, 8 – 13 years) and 851 (54%) in 2005 (wave 3, 13 – 19 years).
Main outcome measures. In both waves participants and their parents completed the PedsQL, a 23-item child HRQoL measure, and BMI z-scores and status (non-overweight, overweight or obese) were calculated from measured height and weight. Associations were tested cross-sectionally and longitudinally (linear regression, adjusted for baseline values)
Results. A total of 81.6% remained in the same BMI category, while 11.4% and 7.0% moved to higher and lower categories, respectively. Cross-sectional inverse associations between lower PedsQL and higher BMI categories were similar to those for elementary school children. Wave 2 BMI strongly predicted wave 3 BMI and wave 2 PedsQL strongly predicted wave 3 PedsQL. Only parent-reported Total PedsQL score predicted higher subsequent BMI, though this effect was small. Wave 2 BMI did not predict wave 3 PedsQL.
Conclusions. This novel study confi rmed previous cross-sectional associations, but did not provide convincing evidence that
BMI is causally associated with falling HRQoL or vice versa across the transition from childhood to adolescence.

Multiple perspectives framework to model complex processes

The growing complexity of organisations has resulted in collaboration between multiple stakeholders becoming a challenging and critical issue that organisations must address in order to ensure their practices are sustainable. A multiple-case field study was conducted in order to demonstrate the proposed methodology of analysis and examination for knowledge-based systems in an actual organisational setting. The use of a multiple-perspective framework to improve understanding of the complex relationships in such systems was examined. In particular, the case study focused on the Australian Government’s Nation Building Economic Stimulus Plan (NBESP) which provided $1.9 billion to construct social housing across the State over two years. The results suggest that the use of a multi-perspective framework is appropriate and that there is a need for attention to be paid to the economic perspective.

Effect of thermal adaptation on outdoor comfort perception

Thermal comfort in outdoor places has proven to have a strong relationship with their users’ attendance and behaviour [1]. Creating comfortable places is therefore to be considered a crucial part of the design process, as taking it into consideration help increasing the social integration between people and therefore fosters sustainability within cities [2]. With the increasing number of migrants within global cities, a new challenge has been facing thermal comfort studies. This challenge is related to the different cultural and climatic origins of those migrants and how they can adapt to the new climatic conditions they are to move in. This paper aims to explore the impact of thermal comfort adaptation on users’ thermal perception in multicultural cities. Consequently, a quantitative field study is applied in Melbourne city, Australia in order to investigate peoples’ outdoor thermal comfort. The analyses were based upon the measurement of climatic parameters that were monitored simultaneously with a questionnaire to determine users’ thermal comfort perception in relation to their time spent in the city. The findings of thermal comfort investigations could be applied into improving the quality of urban areas within global cities and therefore promote the integration within individuals in those societies.

Leptin resistance in a polygenic, hyperleptinemic animal model of obesity and NIDDM : Psammomys obesus

OBJECTIVE: To investigate the effects of leptin administration to Psammomys obesus, a polygenic animal model of obesity and type 2 diabetes mellitus.

DESIGN: Longitudinal intervention study utilising three separate leptin treatment protocols lasting 7-14 d.

MEASUREMENTS: Body weight and food intake were measured daily, body fat and muscle content were estimated by carcass analysis on completion of the study. Blood glucose, plasma insulin, leptin, triglycerides and cholesterol were measured at baseline and twice each week during the study.

RESULTS: Relatively high doses of leptin were required to significantly reduce food intake and body fat content in lean Psammomys obesus, but had no discernible effect on their obese littermates.

CONCLUSION: As a species, Psammomys obesus appear to be relatively insensitive to the effects of leptin administration, compared with other rodents. Obese Psammomys obesus are leptin resistant relative to their lean littermates.

A comparison of Australian rural and metropolitan cardiovascular risk and mortality: the Greater Green Triangle and North West Adelaide population surveys

Objectives:
Cardiovascular (CVD) mortality disparities between rural/regional and urban-dwelling residents of Australia are persistent. Unavailability of biomedical CVD risk factor data has, until now, limited efforts to understand the causes of the disparity. This study aimed to further investigate such disparities.

Students' imaginings of spaces of learning in outdoor and environmental education

In this article, the author interrogates students’ stories about the spaces and places in a tertiary Outdoor and Environmental Education course that support and shape their environmental ethics. Drawing on a longitudinal qualitative study, she explore the ways in which particular sites of learning (outdoor, practical learning) are privileged and how particular stories of outdoor spaces get reproduced. The author employs the work of poststructuralist geography scholar Doreen Massey in her analysis to highlight the intersections between space, relations of power and identity. This analysis also underscores the simultaneity of multiple and conflicting stories around Outdoor Education’s outdoor (practical) and indoor (theoretical) learning spaces. The article concludes by drawing on Elizabeth Ellsworth’s work on anomalous places of learning to explore some of the spaces in-between the indoor/outdoor binary as a way of interrupting and re-imagining places and spaces of learning in Outdoor Education.
