A Non-Gaussian Spatial Process Model for Opacity of Flocculated Paper

ABSTRACT.  Product quality in the paper-making industry can be assessed by opacity of a linear trace through continuous production sheets, summarized in spectral form. We adopt a class of non-Gaussian stochastic models for continuous spatial variation to describe data of this type. The model has flexible covariance structure, physically interpretable parameters and allows several scales of variation for the underlying process. We derive the spectral properties of the model, and develop methods of parameter estimation based on maximum likelihood in the frequency domain. The methods are illustrated using sample data from a UK mill.     

Modelling conditional distributions in bivariate survival

Conditional distributions for bivariate survival can be obtained via a model for the joint distribution, or, as has sometimes been suggested, by modelling the conditioned variable directly, with the conditioning variable included as a covariate. A quantitative comparison of estimated covariate effects and predictive distributions under the two approaches is given. The results are illustrated in a novel frailty application.     

An integrated approach for manpower planning in the service sector

The manpower planning problem receives considerable attention by the management of service organizations because they are typically labor intensive. Not only must optimal staff sizes be determined over an extended horizon, but optimal staff schedules which assign labor to tours of duty and specific tasks, given the available staff size, must also be found. Adding to the complexity arising from the interrelatedness of the staff-sizing and staff-scheduling problems is the existence of the conflicting multiple objectives of minimizing costs and maximizing customer service. The few methodologies reported in the literature which treat the complete manpower planning problem as stated above have several shortcomings. Some techniques place a severe strain on computational capabilities. Also, these methods confound the specification of the goal levels with the analysis of the relative goal weightings. Often the specification of the desired goal levels is made at a different level in the organizational hierarchy than the specification of the relative importance of the various goals. This paper suggests an approach which overcomes these shortcomings. The methodology utilizes a simulation model with an imbedded heuristic procedure for the staff-scheduling problem to identify realistic aggregate staff-size goals to be used in a multiple-objective staff-sizing model. The methodology is applied to the manpower planning problem of a large sectional center post office and the managerial benefits are discussed.     

Contested Housing Landscapes? Social Inclusion,Deinstitutionalisation and Housing Policy in Australia

Deinstitutionalisation is represented as a major step toward social inclusion through the resettlement of disabled people residing in segregated large‐scale institutions into community‐based homes. By promoting the right to live in ordinary community residential settings, deinstitutionalisation fundamentally changes both the support services and housing arrangements of former institutional residents. In Australia, as in many western countries, debates on community care have tended to focus on the location and nature of non‐housing supports for people leaving dependent care. This focus, however, overlooks the fact that deinstitutionalisation involves a radical rehousing of people in care. This paper explores the character and implications of deinstitutionalisation in Australia as a rehousing process. It is based on a recent national research project that has examined the housing futures of people with intellectual disabilities who have been, or will be, deinstitutionalised. The paper considers the increasingly divergent socio‐political perspectives that have emerged in recent discussions about social inclusion, institutional reform and independent living and their implications for housing and community care policies.     

MUSIC,SONG, AND THE CREATION OF COMMUNITY AND COMMUNITY SPIRIT BY A GAY SUBCULTURE

This study looks at the formation of community and the social construction of bridges between communities and the resulting networks. This is accomplished by using a phenomenological approach looking at individual experiences and comparing those against the backdrop of a classical theoretical approach to community. Specifically the study looks at the characteristics of an urban gay choir and its interactions with other communities within their city. The analysis looks towards a better understanding of community bridges and community interaction for a greater cohesion of the public at large and social solidarity development from the standpoint of a marginalized community.     

Putting Principles Into Practice: Addressing Historical Trauma,Mistrust, and Apprehension in Research Methods Courses

The social work profession has articulated commitments to acknowledging and affirming how diversity and culture shape the human experience and to developing social workers who can competently engage in research-informed practice and practice-informed research. However, there remains a need in social work education for more widespread use of culturally relevant pedagogies that can help achieve these goals. Informed by historical trauma theory and the Black perspective, this article presents a model we used for teaching research to master’s-level social work students at a historically Black university. The article describes assignments and classroom exercises that were used and discusses the implications of this model for culturally informed research curricula that promotes antioppressive research in diverse classroom settings.     

Constitutional guarantees to health care in Spain

This analysis of the Spanish health care system is one in a series of such studies undertaken by the author, following a grid of factors that influence the delivery and financing of health care. The purpose of the national analyses is to facilitate a comparison of the United States' and other health care systems in terms of anticipated reform of the U.S. system. Analyses of the U.S. and nine other national systems are included in a book that has just been published by the College. Spain and nine additional countries will be studied in a book due for publication later this year. A final book with ten additional national analyses will appear in 1996.
