VARIABLE WEIGHT DISTRIBUTED LAGS: HOUSING COMPLETIONS IN AUSTRALIA1

This paper presents a convenient way of allowing the weights of a (truncated) geometric lag distribution to vary in the short-run around the average relationship. An alternative version which amounts to an inverted-V lag distribution is developed. The models are applied to the relationship between work done on dwellings and dwelling commencements in Australia over the past decade.     

Professionalization of evaluative research: Conflict as a sign of health

Morell and Flaherty (1978) present arguments about the current status of evaluative research as a profession. This paper contains a critique, using a process model of professional development, of the perspectives employed by Morell and Flaherty. Issues discussed are the nature and substance of conflicts in evaluative research, including conflicts over methodological perspectives, the role of the evaluator in program planning, and the appropriate uses and users of evaluative information. The paper concludes with a discussion of the needs within the profession of evaluative research if it is to remain viable and responsive to change.     

Sexuality and health challenges: responding to a public health imperative

Sexuality is associated with a number of public health imperatives to prevent disease or disability or, if prevention is not possible, to treat and reduce the burden of disease as expeditiously as possible. With the advent of modern testing technology and better sampling of populations, the burden of sexually transmissible infections, sexual assault, and sexual disability have become more apparent. Presented here are U.S. data on the public health dimensions of human sexuality and the evidence for the urgent need to address the magnitude of sexually related public health problems.     

Digital Peer Interactions Affect Risk Taking in Young Adults

Digital interactions are an increasingly common communication method among young adults, but little is known about whether such remote exchanges influence riskiness. The current study examined whether observing and interacting with, versus simply observing, a digital peer affect risk taking in young adults aged 18–25. Participants who remotely viewed risky behavior by a peer or computer increased risk taking; however, compared to a control condition, only exposure to risk‐encouraging messages from a digital peer resulted in sustained risk‐taking behavior. These findings suggest that short text‐based messages from a risk‐encouraging digital peer can influence risk‐taking behavior in young adults. Given the rapid proliferation of digital communication among this age group, these results highlight a potentially important source of peer influence on risky behavior.     

A Social Work Perspective on Seclusion and Restraint in Australia’s Public Mental Health System

A social work perspective of the nature of seclusion and restraint in Australia’s public mental health systems is presented. The article suggests a theme of seclusion and restraint as a regulatory mechanism despite evidence of harm and even death. The case that the use of seclusion and restraint constitutes a social justice issue as it can be understood as an abuse of human rights and form of torture is established. An incident of a person dying in an Australian mental health facility after being secluded is presented to substantiate this claim. An over focus on individual expressions of violence or risk can be at the expense of understanding the systemic and cultural nature of violence in mental health systems. It is important to understand the nature of, and perhaps to question the presumed necessity of, seclusion and restraint practices to ensure that social workers are not breaching their professional obligations to people who are mental health clients.     

Acknowledging and transcending ‘failure’: lifeworld possibilities and system constraints

In this article, we interrogate the concept of methodological ‘failures’ as they arise during fieldwork, in the process of collecting empirical data. We highlight how the techniques of validity horizon matrices and power analysis can be used as methodological tools to illustrate moments in the fieldwork process where these ‘failures’ occur and to illustrate what makes them ‘failures’ rather than just opportunities for learning. Drawing on examples from our own research, we use validity horizon matrices to suggest that ‘failures’ largely occur as a result of disagreements about backgrounded, implicit normative claims. We distinguish between ‘failures’ where communicative possibilities exist for negotiating norms and those where systemic constraints make critique impossible, though we acknowledge that in practice opportunities for negotiating power are limited.     

Retail Agglomeration and Competition Externalities: Evidence from Openings and Closings of Multiline Department Stores in the U.S.

From the perspective of an existing retailer, the optimal size of a cluster of retail activity represents a trade-off between the marginal increases in consumer attraction from another store against the depletion of the customer base caused by an additional competitor. We estimate opening and closing probabilities of multi-line department stores (“anchors”) as a function of preexisting anchors by type of anchor store (low-priced, mid-priced, or high-priced) using a bias-corrected probit model with county and year fixed effects. We find strong negative competitive effects of an additional same type but no effect on openings of anchors of another type.

Environmental quality and the well-being of children

There are many reasons for believing that the environment exerts an influence (directly or indirectly) on the wellbeing of children and families. However, while clear evidence is available that low socioeconomic status is associated with lower than average levels of wellbeing, especially among adults, the evidence linking the social and emotional adjustment of children with the quality of the environment is patchy and equivocal. In this paper we focus on three levels of the family environment: the street, the home and the neighborhood. Neighborhood quality was measured by the Vinson-Homel social problems index, street-type as residential or commercial/retail, and housing quality in terms of upkeep, floor occupied, availability of playspace and occupancy type. The research hypothesis was that after allowing for community selection processes children living in lower quality environments would be less satisfied with various areas of their lives, would experience more negative emotions, and would have more restricted and less positive friendship patterns. The sample comprised 321 families which included a 9–11 year old child, drawn from 18 neighborhoods of Sydney. Neighborhood social problem score and street-type, and some aspects of housing, predicted emotional and social adjustment. Before and after controls for family composition, social class and culture, children living in commercial streets, particularly in inner-city areas, stood out from all others in their feelings of loneliness, dislike of other children and feelings of rejection, worry, fear, anger and unhappiness. Children living in high social problems areas showed a pattern of social constriction rather than maladjustment. These results suggest not simply the influence of social class but genuine community socialization effects. Possible sources of, and mechanisms for, these effects are suggested.     

Refining the association between education and health: The effects of quantity, credential, and selectivity

We refine the established association between education and health by distinguishing three aspects of a person's education (quantity, credential, and selectivity) and by examining the mechanisms through which they may correlate with health. Data are from the 1995 Aging, Status, and the Sense of Control Survey, a representative U.S. national telephone survey of 2,593 respondents aged 18 to 95, with an oversample of elderly. Results show that physical functioning and perceived health increase significantly with years of formal education and with college selectivity for those with a bachelor's or higher degree, adjusting for age, sex, race, marital status, and parental education. The credential of a college degree has no net association with physical functioning and perceived health beyond the amount attributable to the additional years of schooling. Of the three aspects of education, years of schooling has the largest effect. Most of that association appears attributable to its correlation with work and economic conditions, social psychological resources, and health lifestyle. A large portion of the net association of college selectivity with physical functioning and perceived health appears attributable to health lifestyle.
