A general method of constructing E(s2)-optimal supersaturated designs

There has been much recent interest in supersaturated designs and their application in factor screening experiments. Supersaturated designs have mainly been constructed by using the E ( s ²)-optimality criterion originally proposed by Booth and Cox in 1962. However, until now E ( s ²)-optimal designs have only been established with certainty for n experimental runs when the number of factors m is a multiple of n-1 , and in adjacent cases where m = q ( n -1) + r (| r | 2, q an integer). A method of constructing E ( s ²)-optimal designs is presented which allows a reasonably complete solution to be found for various numbers of runs n including n ,=8 12, 16, 20, 24, 32, 40, 48, 64.     

DEMAND/WITHDRAW INTERACTION PATTERNS BETWEEN DIFFERENT TYPES OF BATTERERS AND THEIR SPOUSES

The investigation of subtypes of violent men could provide invaluable information to researchers and clinicians. In earlier studies, investigators examined whether subtypes of male batterers could be identified based on physiological markers in combination with observational and self-report perspectives. In a sample of batterers and their wives, they found a physiological marker that discriminated between two groups of violent men on several interesting dimensions. To highlight the importance of studying batterer typologies, the present study examined differences in marital interaction patterns across the two groups of batterers. Analyses revealed clinically relevant patterns of interaction in the two groups, and effect sizes indicating the possibility of differences between the two types of batterers. Implications for future research as well as therapy are discussed.     

The peculiar shrinkage properties of partial least squares regression

Partial least squares regression has been widely adopted within some areas as a useful alternative to ordinary least squares regression in the manner of other shrinkage methods such as principal components regression and ridge regression. In this paper we examine the nature of this shrinkage and demonstrate that partial least squares regression exhibits some undesirable properties.     

The Role and Function of the Faculty Field Liaison

This article examines the purposes, defines the role, and analyzes the functions of a faculty field liaison. It reflects the experience of faculty members who have carried this assignment as a major responsibility. In recognition of the impact of this role on the educational process and the need for it to be clearly understood, the authors have attempted to distill its essence and to clarify the requirements for its effective practice.     

Crime,antisocial personality and pathological gambling

To investigate the hypothesized causal relationship between pathological gambling and gambling-related illegal behaviors, 77 patients seeking behavioral treatment for excessive gambling and 32 members of Gamblers Anonymous were administered a structured interview schedule. Data on the incidence, nature and extent of both gambling and non-gambling related illegal behaviors was obtained and DSM-III (A.P.A., 1980) criteria for Antisocial personality were used as the measure of sociopathy.Of the sample, 54.1% admitted to a gambling related offense and 21.1% were charged. Results showed that 14.6% met DSM-III criteria for Antisocial Personality, Four subgroups were subsequently identified; gamblers who committed no offense (36.7%), gambling only offenses (40.4%), non-gambling only offenses (9.2%) or both gambling and non-gambling offenses (13.7%). Significantly more subjects from the gambling plus non-gambling related offenses subgroup were classified as antisocial personalities.Of pathological gamblers who committed offenses, two thirds reportedly did so as a direct consequence of gambling induced problems. Subjects reporting gambling-only related offenses showed a significant increase in antisocial features after adolescence suggesting that antisocial features emerge as a secondary phenomenon to pathological gambling behavior patterns.Acknowledgments: This study was made possible by a grant from the Criminology Research Council, Australian Institute of Criminology.     

Visual Access and Attention in Two‐Year‐Olds' Event Reasoning and Object Search

Several recent studies have revealed substantial limitations in 2‐year‐olds' ability to search accurately for objects that have undergone unseen movement, even along highly constrained paths. In many of these studies, children observed a ball as it rolled down a track and behind an occluding panel that contained 4 doors. The track had a barrier that was partly visible and could be placed in locations corresponding to the doors. When the ball came to a rest against the barrier and behind the occluder, the child's task was to find the ball by opening the correct door. The search accuracy of 2‐year‐olds has not differed from chance across several variations of this task. This research was conducted to identify the source of 2‐year‐olds' limitation in this domain. Children were granted a full view of the event before the ball was occluded with a door panel. Children's performance was better under this condition, but was still not systematically accurate unless their gaze remained locked onto the correct location. Two‐year‐olds' weak performance in these search tasks appears to be more a consequence of limitations in spatial integration than in their representation of unseen movement.     

New community governance in small rural towns: the Australian experience

State and federal governments in Australia have developed a range of policy instruments for rural areas in Australia that are infused with a new sense of ‘community’, employing leading concepts like social capital, social enterprise, community development, partnerships and community building. This has encouraged local people and organisations to play a greater role in the provision of their local services and has led to the development of a variety of ‘community’ organisations aimed at stemming social and economic decline. In Victoria, local decision-making, before municipal amalgamations, gave small towns some sense of autonomy and some discretion over their affairs. However, following municipal amalgamations these small towns lost many of the resources—legal, financial, political, informational and organisational—associated with their former municipal status. This left a vacuum in these communities and the outcome was the emergence of local development groups. Some of these groups are new but many of them are organisations that have been reconstituted as groups with a broader community focus. The outcomes have varied from place to place but overall there has been a significant shift in governance processes at community level. This paper looks at the processes of ‘community governance’ and how it applies in a number of case studies in Victoria.     

Correlates of physical violence at school: A multilevel analysis of Australian high school students

Studies of school violence have been generally been informed either by social disorganisation or social control theory. However applications of social disorganisation theory to school violence sometimes make little attempt to control for individual differences in propensity to violent behaviour. This study of 2,616 Australian high school students uses multilevel modelling techniques to see whether various characteristics of the school (e.g. lack of clarity about school rules, school responsiveness to racism, school size, ethnic composition) are related to the risk of physical violence between students, once individual and family risk factors for violent behaviour have been taken into account. The results suggest that school characteristics and developmental factors both play an important role in shaping the risk of violence at school.     

Children, death and ageism

The position of children in the social order can be seen as an ambiguous one. On the one hand, they are highly valued, at a rhetorical level at least, as the basis of the future generation. On the other hand, however, they can be seen to be marginalized and disenfranchised, protected from more aspects of social life than is strictly necessary. This paper explores some of the important issues relating to children's disenfranchised social position, with specific reference to issues relating to death, dying and bereavement.
