A suite of visual languages for model-driven development of statistical surveys and services

Objective: To provide statistician end users with a visual language environment for complex statistical survey design and implementation. Methods: We have developed, in conjunction with professional statisticians, the Statistical Design Language (SDL), an integrated suite of visual languages aimed at supporting the process of designing statistical surveys, and its support environment, SDLTool. SDL comprises five diagrammatic notations: survey diagrams, data diagrams, technique diagrams, task diagrams and process diagrams. SDLTool provides an integrated environment supporting design, coordination, execution, sharing and publication of complex statistical survey techniques as web services. SDLTool allows association of model components with survey artefacts, including data sets, metadata, and statistical package analysis scripts, with the ability to execute elements of the survey design model to implement survey analysis. Results: We describe three evaluations of SDL and SDLTool: use of the notation by expert statistician to design and execute surveys; useability evaluation of the environment; and assessment of several generated statistical analysis web services. Conclusion: We have shown the effectiveness of SDLTool for supporting statistical survey design and implementation. Practice implications: We have developed a more effective approach to supporting statisticians in their survey design work.

Developing an approach to assess the influence of integrating disaster risk reduction practices into infrastructure reconstruction on socio-economic development

Purpose: Disasters provide physical, social, economic, political and environmental development windows of opportunity particularly through housing and infrastructure reconstruction. The reconstruction process should not be neglected due to the opportunistic nature of facilitating innovation in development. In this respect, post-disaster "infrastructure" reconstruction plays a critical role in development discourse and is often essential to sustain recovery after major disasters. However, reconstruction following a natural disaster is a complicated problem involving social, economic, cultural, environmental, psychological, and technological aspects. There are significant development benefits of well-developed "Disaster Risk Reduction (DRR) Strategies" and, for many reasons, the concept of DRR can be more easily promoted following a disaster. In this respect, a research study was conducted to investigate the effects of integrating DRR strategies into infrastructure reconstruction on enhancing the socio-economic development process from a qualitative stance. The purpose of this paper is to document part of this research study; it proposes an approach that can be used to assess the influence of the application of the DRR concept into infrastructure reconstruction on socio-economic development. Design/methodology/approach: The research methodology included a critical literature review. Findings: This paper suggests that the best way to assess the influence of integrating DRR strategies practices into infrastructure reconstruction on socio-economic development is to assess the level of impact that DRR strategies has on overcoming various factors that form vulnerabilities. Having assessed this, the next step is to assess the influence of overcoming the factors that form vulnerabilities on achieving performance targets of socio-economic development. Originality/value: This paper primarily presents a framework for the concept of socio-economic development and a modelled classification of DRR practices.

Opportunities and challenges in developing a whole-of-government national food and nutrition policy: lessons from Australia's National Food Plan

OBJECTIVE: The present article tracks the development of the Australian National Food Plan as a 'whole of government' food policy that aimed to integrate elements of nutrition and sustainability alongside economic objectives. DESIGN: The article uses policy analysis to explore the processes of consultation and stakeholder involvement in the development of the National Food Plan, focusing on actors from the sectors of industry, civil society and government. Existing documentation and submissions to the Plan were used as data sources. Models of health policy analysis and policy streams were employed to analyse policy development processes. SETTING: Australia. SUBJECTS: Australian food policy stakeholders. RESULTS: The development of the Plan was influenced by powerful industry groups and stakeholder engagement by the lead ministry favoured the involvement of actors representing the food and agriculture industries. Public health nutrition and civil society relied on traditional methods of policy influence, and the public health nutrition movement failed to develop a unified cross-sector alliance, while the private sector engaged in different ways and presented a united front. The National Food Plan failed to deliver an integrated food policy for Australia. Nutrition and sustainability were effectively sidelined due to the focus on global food production and positioning Australia as a food 'superpower' that could take advantage of the anticipated 'dining boom' as incomes rose in the Asia-Pacific region. CONCLUSIONS: New forms of industry influence are emerging in the food policy arena and public health nutrition will need to adopt new approaches to influencing public policy.

Challenges to providing work integrated learning to international business students at Australian universities

Purpose – The purpose of this paper is to report on a three-year Australian study of international business and accounting students and the transition to employment. For international students seeking to differentiate themselves in a highly competitive global labour market, foreign work experience is now an integral part of the overseas study “package”. Work-integrated learning (WIL) is seen to provide critical “employability” knowledge and skills, however, international students have low participation rates. The high value placed on WIL among international students poses challenges for Australia as well as opportunities. Understanding the issues surrounding international students and WIL is closely linked to Australia’s continued success in the international education sector which has broad, long-term, social and economic implications.Design/methodology/approach – This paper draws on 59 interviews with a range of stakeholders including international students, universities, government, employers and professional bodies. Central to the paper is an in-depth case study of WIL in the business and accounting discipline at one Australian university.Findings – Providing international students with access to discipline-related work experience has emerged as a critical issue for Australian universities. The study finds that enhancing the employability skills of internationals students via integrated career education, a focus on English language proficiency and “soft skills” development are central to success in WIL. Meeting the growing demand for WIL among international students requires a multipronged approach which hinges on cooperation between international students, universities, employers and government.Originality/value – This project aims to fill a critical knowledge gap by advancing theories in relation to international students and WIL. While there is a significant body of research in the fields of international education and WIL, there is an absence of research exploring the intersection between the two fields. The study will contribute to the advancement of knowledge in both fields by exploring the emerging issue of WIL and international students.

Multi-market industrial organizational economic models for the internationalization process by small and medium enterprise construction design service firms

Small and medium enterprises (SMEs) are critical to strategic initiatives in an economy; however, their contribution to foreign trade is not as significant. SMEs are one of the principal driving forces in economic development. One of the greatest challenges is the internationalization process for longevity rather than seeing the process as initial market entry. The internationalization process research has typically involved four key constructs: market selection, decision to enter, entry modes and factors affecting entry modes. Past research has focused on large manufacturing firms. The export of architectural, engineering and construction (AEC) firms has undergone growth, yet there is still significant opportunity for further growth. The majority of AEC firms are SMEs. Notwithstanding assistance provided through international trade missions, organized export firm support networks and information packages by a burgeoning number of government agencies, there are still perceived barriers to market entry and long-term economic sustainability for SMEs. There are a number of problems faced by SMEs acting in foreign trade. This investigation explores the successful initial internationalization process constructs and identifies unique project-oriented sector characteristics. The study identified similarities and differences between two firms that have been exporting to various localities, including Eastern Europe, Africa, Middle East, UK, Asia and South America, for more than two decades. The similarities and differences were identified within eight major constructs: purpose, firm type, market image and design philosophy, entry mode strategy, institutional arrangement, factors affecting mode of entry, market selection and firm strategy in relation to project selection. The primary reasons for internationalization were associated with the firms' motivations related to growth and financial viability. This article discusses the various internationalization processes and strategies intrinsic to each case study and establishes a detailed set of empirical observations from which to develop further a grounded theoretical model of reflexive capability for the internationalization process. This study contributes to the body of knowledge around the SME AEC design service firm's internationalization process, as a dynamic, evolving and continuously adaptable construct for project-based sectors.

Understanding the role of mediating risk factors and proxy effects in the association between socio-economic status and untreated hypertension

The association between socio-economic status (SES) and untreated hypertension varies according to a country's level of development and racial/ethnic group. We sought to confirm this variation in women from China and the United States (US) as well as to investigate the impact of SES on several mediating risk factors. We also investigate the extent to which SES explains racial/ethnic differences in untreated hypertension in the US. We used cross-sectional data from 1814 non-pregnant women in China (China Health and Nutrition Survey (CHNS), 1997) and 3266 non-pregnant women in the United States (National Health and Nutrition Examination Survey (NHANES III), 1988–1994) respectively. A variety of statistical modelling techniques was used to predict untreated hypertension as a function of several mediating factors and to simulate the impact of changes in SES. The age-adjusted prevalence of untreated hypertension was significantly higher (p<0.01) for low-income White and Black women compared to Mexican American or Chinese women. Untreated hypertension was not significantly associated with income or education in Mexican Americans or women in China. Obesity and light physical activity had the largest mediating effect on the association between SES and untreated hypertension for all racial/ethnic groups. However, this effect was not as strong as the proxy effect of income and education. SES did not completely explain racial/ethnic differences in hypertension in the US. While SES was more strongly associated with hypertension in Blacks than Whites, Blacks were still 1.97 (95% CI 1.47–2.64) times more likely to have untreated hypertension than Whites after adjusting for SES differences. The association between SES and untreated hypertension varied by country and racial/ethnic group. An important explanation for this variation was the differential effect of SES on mediating risk factors. SES disparities between Whites and Blacks in the US partly explain differences in the prevalence of untreated hypertension between these racial/ethnic groups.

CH2 energy harvesting systems : economic use and efficiency

This paper looks at the City of Melbourne's new office development CH₂ as a case study of world class energy performance. In particular, the integrated design of conventionally independent systems has led to the potential to deliver significant savings to the Council and to deliver better environmental conditions to building occupants that in turn may contribute to satisfaction, well-being and Productivity. It is concluded that this project has the potential
to be an iconic example of effective implementation of ESD (environmental sustainable design) principles and therefore act as a demonstration project to others. Energy efficiency of more than 50% of current benchmarks for Melbourne is effected. Energy harvesting is defined as arising from squander, waste and nature, which is a new concept introduced in this paper to better describe the design decision process.

Economic performance analysis of the Australian property sector using input-output tables

The property sector has played an important role with its growing contribution in the national income and employment in the Australian economy. There is an increasing research need in measuring and analysing the economic performance of the Australian property sector at a country level and input-output tables are considered as an appropriate tool. This paper aims to analyse and measure the performance and sectoral linkages of the Australian property sector using the five latest input-output tables compiled by the Australian Bureau of Statistics. Findings suggested that the Australian residential property sector had played a more important role than the commercial sector in the economy. The backward linkage of the residential property sector showed a decreasing economic pull, while that of commercial property presented an upward pattern. Moreover. the Australian property sector showed a medium economic push to the national economy over the examined period. Findings can aid policy makers, the property sector and researchers in evaluating the competitive ability of the property sector in Australia.

Socio-economic inequalities in women`s fruit and vegetable intakes: a multilevel study of individual, social and environmental mediators

Objective: This study employed a multilevel design to test the contribution of individual, social and environmental factors to mediating socio-economic status (SES) inequalities in fruit and vegetable consumption among women. Design: A cross-sectional survey was linked with objective environmental data. Setting: A community sample involving 45 neighbourhoods. Subjects: In total, 1347 women from 45 neighbourhoods provided survey data on their SES (highest education level), nutrition knowledge, health considerations related to food purchasing, and social support for healthy eating. These data were linked with objective environmental data on the density of supermarkets and fruit and vegetable outlets in local neighbourhoods. Results: Multilevel modelling showed that individual and social factors partly mediated, but did not completely explain, SES variations in fruit and vegetable consumption. Store density did not mediate the relationship of SES with fruit or vegetable consumption. Conclusions: Nutrition promotion interventions should focus on enhancing nutrition knowledge and health considerations underlying food purchasing in order to promote healthy eating, particularly among those who are socio-economically disadvantaged. Further investigation is required to identify additional potential mediators of SES–diet relationships, particularly at the environmental level.

Economic evaluation of Australian stroke services: a prospective, multicenter study comparing dedicated stroke units with other care modalities

Background and Purpose: Level I evidence from randomized controlled trials demonstrates that the model of hospital care influences stroke outcomes; however, the economic evaluation of such is limited. An economic appraisal of 3 acute stroke care models was facilitated through the Stroke Care Outcomes: Providing Effective Services (SCOPES) study in Melbourne, Australia. The aim was to describe resource use up to 28 weeks poststroke for each model and examine the cost-effectiveness of stroke care units (SCUs). Methods: A prospective, multicenter, cohort study design was used. Costs and outcomes of stroke patients receiving 100% treatment in 1 of 3 inpatient care models (SCUs, mobile service, conventional care) were compared. Health-sector resource use up to 28 weeks was measured in 1999. Outcomes were thorough adherence to a suite of important clinical processes and the number of severe inpatient complications. Results: The sample comprised 395 participants (mean age 73 [SD 14], 77% first-ever strokes, males 53%). When compared with conventional care (n=84), costs for mobile service (n=209) were significantly higher (P=0.024), but borderline for SCU (n=102, P=0.08; $AUD12 251; $AUD15 903; $AUD15 383 respectively). This was primarily explained by the greater use of specialist medical services. The incremental cost-effectiveness of SCUs over conventional care was $AUD9867 per patient achieving thorough adherence to clinical processes and $AUD16 372 per patient with severe complications avoided, based on costs to 28 weeks. Conclusions: Although acute SCU costs are generally higher, they are more cost-effective than either mobile service or conventional care.

The measurement of trust in inter-organisational networks: a conceptual framework and research design

The aim of this paper is to outline a conceptual model and research design for measuring trust in inter-organisational networks which has the potential to be a ‘blueprint’ for a large-scale, multilevel study of trust in networks. Inter-organisational networks are increasingly recognised as a means to achieve economic and social exchange yet, how these networks operate is less widely understood. Trust is widely identified as being essential to the functioning of networks forms of organisation. In order to analyse trust in networks the Social Relations Model (Kenny 1994) of interpersonal perception is applied here. Insights from this model are used to specify relevant components of trust; and extended by incorporating measures of trust at the level of the work group.

University planning and design under confucianism, colonialism, communism and capitalism : the Vietnamese experience

The university in Vietnam represents a thread of continuity that has managed to survive the political, economic and social turmoil faced so frequently by the Vietnamese people. This paper traces the evolution of the Vietnamese university in terms of its site planning and building design from the Hanoi Van Mieu, a Confucian 'temple of literature' which, built in 1070AD, is regarded as the country's first university, to today’s system of general and specialised universities and polytechnic institutions. In the late 1990s another step in the process of evolution began with the rationalization and amalgamation of the tertiary system to form two large, multi-campus and multi-disciplinary universities – the Hanoi National University and the Ho Chi Minh National University.

Defuturing an architecture of destruction: a reconciliation of Van Berkel and Bos to the new design philosophy of Tony Fry

For some time now Tony Fry has promoted the idea of 'The Sustainment', an idea that asserts a paradigm shift in attitudes to consumption. 'The Sustainment' recognises that increasingly human futures are products of self-determination and not chance. Fry’s hypothesis can be understood through his concept of Defuturing, a philosophy that questions the role of design and the responsibility of designers to facilitating the ability to sustain (Fry 1999).
Central to Fry’s philosophy is an awareness that it is in the best interests of designers and their clients, as inhabitants of cultures increasingly driven by technology, to be aware of the relationships between the products and theories of design and the processes and implications of technological change. This is an awareness that is central to the concepts, work, and methodologies of the ‘UN Studio’ of Van Berkel and Bos described and elaborated upon in Move – Imagination, Techniques, and Effects (Van Berkel & Bos 1999). Here, Ben Van Berkel defines the parameters and methodologies employed by UN Studio in an environment of technological and socio-economic change. The Dutch practice could be said to exemplify something of a zeitgeist in current architectural design that sees architects, as Van Berkel and Bos view them, as “fashion designers of the future, dressing events to come and holding up a mirror to the world (Van Berkel & Bos 1999, back cover).” It is a zeitgeist that Fry might see as aligned to the resilient hype of ‘new creativity’, ‘globalisation’ the ‘romance with technology’, and the vacuous-ness of the world of fashion. (Fry The Voice of Sustainment: on Design Intelligence 2005).
A source of breaking down such design propaganda is identified by Fry in the notion of ‘scenarios,’ which “provide a mechanism for politico-practice assemblage in which dialogues and narratives of change can be rehearsed in ways that enable participants to re-educate themselves via critical confrontations” (Fry The Voice of Sustainment: on Design Intelligence 2005). From such a perspective this paper aims to practically illustrate and ground the Defuturing of Fry by establishing a dialogue between his writings and the theories that have generated the architectural designs of Van Berkel and Bos and there UN Studio. This will be a ‘scenario’ that examines therefore an appropriation and transformation of the applied intellectual practice of Van Berkel and Bos. Through this confrontation we shall explore the question of why sustainability appears to be so low in the agenda of many pre-eminent contemporary architects, and how we might refocus therefore practice and theory on the ability to sustain.
