Household composition and housing expenditures in rental-occupied and owner-occupied markets

This article examines the relationship between household compositions and housing expenditures in rental-occupied and owner-occupied markets. The author finds that renters allocate their budget proportionately between housing and nonhousing goods for an additional household member, leaving the budget share of housing expenditures unchanged. For homeowners, nevertheless, an extra member implies a reduction in housing expenditures as a share of total budget. Although age and gender compositions turn out to be significant in determining the budget share of housing expenditures for renters, they play no major role for homeowners. And although an increase in the number of working members for renters significantly reduces the share of budget spent on housing, it has no significant impact for their owner counterparts. Moreover, keeping total expenditures constant, the main income source of the head of the household does not make any difference in terms of resource allocation across housing and nonhousing goods for both renters and owners.

Towards prefabricated sustainable housing - an introduction

Prefabricated building systems are once again gaining popularity. The new prefabricated paradigm offers the integration of several approaches previously ignored: automated manufacturing, integrated building services and environmental sustainable principles. Consistency, predictable environmental control, modular flexibility, quick assembly and affordability are promising features of modern manufactured construction. Though the concept of prefabricated building is not new, this type of construction may be the only hope in obtaining a truely sustainable architecture for our future.

This paper attempts to define and evaluate several prefabricated building systems, ranging from a ‘kit-of-parts’ to fully assembled ‘volumetric’ modules. It aims to categorise various manufactured types among a vast amount of information, and to observe their attributes regarding materials, flexibility, structural integrity, delivery and constructability. This paper suggests that pre-fabricated architecture can deliver high order design and diversity within the framework of waste reduction, renewable systems integration and optimal performance.

Ethnography of housing : a conclusion

This paper is the final report of a research project spanning three years, exploring three field locations and capturing the stories of forty (plus) housing workers. Using an ethnographic research approach, this paper provides an account of how housing workers use language and stories to understand and make sense of their challenging and changing work. First hand accounts ('stories') about every day housing work frame the data in this paper, explaining how housing workers in Victoria have experienced and made sense of the shift from public housing as 'affordable housing for the working poor' to 'housing of last resort for the most vulnerable and needy members of the community'. Using a number of composite stories, this paper provides the reader with a glimpse into the work of public housing staff, transporting the leader from the relatively static world of policy and procedure to the more colorful world of tenants with 'high and complex' needs, 'wicked' problems, weary staff and the daily reality of organisational change.

A unique feature of this research is the comparison of how different workers use stories to build a range of 'socially constructed realities' around the housing work and its wicked problems. This paper compares and contrasts the socially constructed realities of frontline staff with the corresponding social realities of the managers at head office (and vice versa). This 'same problem, different perspective' approach allows the reader to better understand how the same problem is understood and approached in different ways, depending on the individual's organisational role, responsibly and authority. Using stories about 'working with problem tenants', 'collecting rental arrears from the poor and marginalised', 'maintaining old, neglected properties' and 'coping with organisational change', this paper illustrates how the shifting (and sometimes contradictory) construction of housing problems has meant that the organisation has long struggled to devise and implement sustainable remedies to these problems.

The following pages describe how the problems identified in the Housing Office Review (and experienced in the daily work of the 'modern day' housing worker) are simply a contemporary manifestation of 'age old public housing issues'. This paper describes and explains how housing staff have long used narrative to make sense of their often difficult work and ultimately, how they understand and experience a major process of operational policy change associated with the shift from 'public' housing to 'welfare' housing.

A question of continuing control -balancing building quality of housing and building codes

The Building Code of Australia seeks to establish “nationally consistent, minimum necessary standards of relevant, health, safety (including structural safety and safety from fire), amenity and sustainability objectives efficiently”. These goals are laudable – but where are the goals of quality and maintenance, which are also an essential part of achieving adequate and continuing health and safety for the built environment?

Defects such as dampness, settlement and cracking, staining, wood rot, termite damage, rusting, and roof leakage are common enough to suggest that there are still issues with building quality in housing. They are caused by a combination of initial poor workmanship and poor quality materials and latterly by poorly executed or inadequate maintenance.

Local architecture, developed over many years of trial and error, produce buildings linked to their climate and local materials (think of the typical “Queenslander” house). Today’s architecture imports technologies and materials from many differing countries and climates – that are not necessarily suitable for the location, nor is there necessarily the same quality control over the material quality and production. Inappropriate use and inadequate understanding of new materials and techniques can lead to the generation of further defects.

Whilst the building code contains provisions for initial-build material quality and workmanship, there is no continuing control over a house over its life span. Reliance is placed on advertising the need, for example, to employ qualified tradespeople; replace batteries in smoke detectors; and other good advice to help maintain housing to a minimum standard. Is this sufficient?

Mechanisms to make the transfer of knowledge to those who need to use it – be it the workforce or the houseowner – need to be improved. Should the building code be more visual and accessible in it’s content? Should the building code include provisions for maintenance? Should the building code require every house to have a “users manual” – much like a car? An extensive review of literature identifies the scale of the problem of poor quality housing and highlights some suggested causes – inadequate knowledge of the BCA by general housebuilders being one. However little work has been done to investigate what could be done to improve the situation. This work suggests that improvements to knowledge transfer would improve the quality of housing and a model of the knowledge transfer process is proposed, identifying those areas where the knowledge flows need to occur that would impact both the builders and users of housing.

Similar metabolic adaptations during exercise after low volume sprint interval and traditional endurance training in humans

Low-volume ‘sprint’ interval training (SIT) stimulates rapid improvements in muscle oxidative capacity that are comparable to levels reached following traditional endurance training (ET) but no study has examined metabolic adaptations during exercise after these different training strategies. We hypothesized that SIT and ET would induce similar adaptations in markers of skeletal muscle carbohydrate (CHO) and lipid metabolism and metabolic control during exercise despite large differences in training volume and time commitment. Active but untrained subjects (23 ± 1 years) performed a constant-load cycling challenge (1 h at 65% of peak oxygen uptake before and after 6 weeks of either SIT or ET (n = 5 men and 5 women per group). SIT consisted of four to six repeats of a 30 s ‘all out’ Wingate Test (mean power output ∼500 W) with 4.5 min recovery between repeats, 3 days per week. ET consisted of 40–60 min of continuous cycling at a workload that elicited ∼65% (mean power output ∼150 W) per day, 5 days per week. Weekly time commitment (∼1.5 versus ∼4.5 h) and total training volume (∼225 versus ∼2250 kJ week−1) were substantially lower in SIT versus ET. Despite these differences, both protocols induced similar increases (P < 0.05) in mitochondrial markers for skeletal muscle CHO (pyruvate dehydrogenase E1α protein content) and lipid oxidation (3-hydroxyacyl CoA dehydrogenase maximal activity) and protein content of peroxisome proliferator-activated receptor-γ coactivator-1α. Glycogen and phosphocreatine utilization during exercise were reduced after training, and calculated rates of whole-body CHO and lipid oxidation were decreased and increased, respectively, with no differences between groups (all main effects, P < 0.05). Given the markedly lower training volume in the SIT group, these data suggest that high-intensity interval training is a time-efficient strategy to increase skeletal muscle oxidative capacity and induce specific metabolic adaptations during exercise that are comparable to traditional ET.

Living high but healthy : high-rise housing, nature, health and wellbeing

This exploratory mixed method study investigated the factors, including access to nature (i.e. parks and gardens), impacting on inner city high-rise residents' health and wellbeing. Analysis of the integrated findings revealed that a range of factors (including accessibility, choice and control and tenure) impact on residents' health and wellbeing.

Malaysia's terraced housing : towards an environmentally sustainable future

Housing developers in Malaysia have been focusing on providing more homes to deal with the ever growing urban population, and have failed to address environmental issues which run parallel to these housing developments. The thesis identifies and suggests possible actions enabling future housing developments to incorporate sustainable elements.

Analysis of public housing standards in Victoria : 1939-1995

The "housing standard" is a government policy document which defines minimum dwelling standards. This thesis outlines the development of public housing standards in Victoria between 1939 and 1995. The Hotham Housing Estate, North Melbourne, was the case study from which a proposed framework for critical analysis of minimum housing standards was derived.

Association of western and traditional diets with depression and anxiety in women

Objective: Key biological factors that influence the development of depression are modified by diet. This study examined the extent to which the high-prevalence mental disorders are related to habitual diet in 1,046 women ages 20–93 years randomly selected from the population.

Method: A diet quality score was derived from answers to a food frequency questionnaire, and a factor analysis identified habitual dietary patterns. The 12-item General Health Questionnaire (GHQ-12) was used to measure psychological symptoms, and a structured clinical interview was used to assess current depressive and anxiety disorders.

Results: After adjustments for age, socioeconomic status, education, and health behaviors, a "traditional" dietary pattern characterized by vegetables, fruit, meat, fish, and whole grains was associated with lower odds for major depression or dysthymia and for anxiety disorders. A "western" diet of processed or fried foods, refined grains, sugary products, and beer was associated with a higher GHQ-12 score. There was also an inverse association between diet quality score and GHQ-12 score that was not confounded by age, socioeconomic status, education, or other health behaviors.

Conclusions: These results demonstrate an association between habitual diet quality and the high-prevalence mental disorders, although reverse causality and confounding cannot be ruled out as explanations. Further prospective studies are warranted.

Migrant housing in the city and the village : from Melbourne to Zavoj

This paper will discuss the kinds of communities that evolve through historical practices of migration. The migrant house is associated with a new architecture that hod appeared in the cities of immigration of the new worlds (Melbourne, Toronto, Chicago). It is perceived as a stereotypical symbolisation of immigrants from Southern European origins that had arrived in the decades following the Second World War. The appearance of houses built by returning migrants in sites of origin suggests other traiectories, other modes of travel, and other forms of community. Central to the thesis of this paper is the testimony of two types of migrant houses. The study draws on theories of migration that address the site of departure, the site of arrival, and the question and conflict of return which is at the centre of the migrant's imaginary. This study will examine the migrant houses in the village of emigration (Zavoj in Macedonia), migrant houses built by returning emigrants. A study of the two houses of migration implicates a set of networks, forces, relations, circumscribing a large global geopolitical and cultural field that questions our understandings of diaspora, the binary structure of dwelling/travelling, and the fabric and fabrication of community. In addition, the paper will explore the notion of house as an imaginary landscape, a psychic geography narrated through migratory travels.

'Build it, fill it and bill it' : how work in the public housing sector has changed (and stayed the same)

This paper is an ethnographic account of how 'wicked' (i.e. entrenched and enduring) problems with the 'building, filling and billing' of public housing have shaped and influenced the work of public housing workers in Victoria, Australia. With a few exceptions, the front line work of housing staff is represented in the literature as smaller, constituent parts of some larger policy process, organisational event or procedural reform. In order to understand how housing work has been constructed over time, this paper attempts to consolidate these fragmented narratives (contained in old documents, training manuals, news articles and reports) into an historical account of 'what it was like' to work in the public/social housing sector. In this paper, I will construct this 'historical account' with the stories I gathered over twelve months of field work in three different public housing offices. In their stories, public housing workers tell me how subtle and incremental has been the change to their work, how increasingly complex are the needs of tenants and how dfficult their work has become. Their stories illustrate the complexity of undersdanding and addressing these 'wicked' housing problems when tenants change, staff change and
the public housing sector has a history of frequent 'restructuring'. This contextualisation of 'old and new stories' will allow the reader to understand how the organisational reality of present day housing work has been socially constructed ('sedimented') by generation, of workers, managers and tenants.
