Hazardous Wastes — New Developments

Abstract

Recent developments in the field of hazardous wastes management have forced officials of health care facilities or health-related research facilities and institutions to reevaluate their handling and disposal methods for adequate protection of health, safety, and the environment. In addition to the problems associated with medical or pathological wastes are an entirely new set of problems associated with the disposal of waste chemicals. New disposal strategies must be developed to address these problems and to meet evolving regulatory requirements.

A study was undertaken to explore technologies available for the destruction of waste chemicals where they are generated. Although no technology was capable of safely destroying all conceivable waste chemicals, it did appear that incineration offered significant promise. To support this conclusion, five different incinerators were field tested for various pollution parameters when burning a test charge of waste chemicals.

The results of the testing were quite encouraging. Three of the five units tested easily met the Federal particulate requirement for incinerators. The measured results for unburned hydrocarbons, hydrogen chloride, sulfur oxides, and oxides of nitrogen were also low enough to support further pursuit of this option. As a result of this testing, a unit will be procured for more refined testing on various chemical wastes on a case-by-case basis, so that a high level of confidence can be developed.     

A Quiet Suffering: Some Notes on the Sociology of Suffering1

Despite a recent increase in attention within the social sciences, suffering remains for the most part outside of the purview of sociologists. In this essay, I explore the possibilities for a sociology of suffering by briefly interrogating suffering in the aftermath of Hurricane Katrina in the Lower Ninth Ward, the epicenter of the hurricane and the federal levee failures.     

Financial Attitudes and Inter vivos Resource Transfers from Older Parents to Adult Children

This exploratory study combines economic, family, and decision-making conceptual models to investigate the factors influencing resource transfers as reported by older adults. Pilot data on 61 adult children was obtained during face-to-face interviews with 18 older parents. Hierarchical multiple regressions were conducted to predict time (emotional support) and financial (cash and gifts) inter vivos transfers from demands, resources, values, and relationships. Positive health ratings, strong affection for the adult child, and money retention attitudes were associated with frequent emotional support. Small household size predicted frequent financial transfers. Results indicate the importance of values, resources, demands, and relationships in predicting resource transfers from older parent to adult child.     

Protection studies: Challenging oppression and discrimination

Social work students on qualifying programmes should have abundant opportunities to challenge racism, sexism, disablism and other oppressions in society, that is in the macro environment. Equally they are required to confront oppression in the micro environments of the family home or small institution. One way of achieving this is through integration of the issues into the whole curriculum but also through a specific module devoted to protection studies.

Child and ‘elder’ abuse and the mistreatment of dependent younger adults is at one end of a continuum of oppression with societal discrimination at the other. Oppression, whatever its form, has four essential components: the misuse of power, processes of objectification, the silence of witnesses and the entrapment or accommodation of victims. Social work students who do not fully appreciate the dynamics of the abuse of power, and the perspectives of victims are ill equipped to challenge oppression.

A rationale for a protection studies module is given. The objectives and content of the proposed studies are also suggested. Protection studies, it is argued, are essential because social workers are faced with complex issues of power and control. Those who overlook the need to protect all of society's weakest members can be seen as facilitating abusers in the same way that those who do not embrace anti-discriminatory and anti-oppressive practices are perpetuating bigotry and injustice.     

Trends and Cycles in Macroeconomic Time Series

Two structural time series models for annual observations are constructed in terms of trend, cycle, and irregular components. The models are then estimated via the Kalman filter using data on five U.S. macroeconomic time series. The results provide some interesting insights into the dynamic structure of the series, particularly with respect to cyclical behavior. At the same time, they illustrate the development of a model selection strategy for structural time series models.     

Multilevel multivariate modelling of childhood growth, numbers of growth measurements and adult characteristics

Summary.  A general latent normal model for multilevel data with mixtures of response types is extended in the case of ordered responses to deal with variates having a large number of categories and including count data. An example is analysed by using repeated measures data on child growth and adult measures of body mass index and glucose. Applications are described that are concerned with the flexible prediction of adult measurements from collections of growth measurements and for studying the relationship between the number of measurement occasions and growth trajectories.
