Determinants of Black Suburbanization: Regional and Suburban Size Category Patterns*

This study analyzes the movement of blacks to the suburbs of American metropolitan areas, using the framework developed by Taeuber and Taeuber (1965) for the analysis of racial transition in inner city neighborhoods. The data are consistent with their model and suggest that the rate of black population growth is a function not only of the characteristies of individual suburbs themselves, but also of the central cities of the metropolitan areas within which they are located. The units of analysis are all suburbs with populations of 10,000 or more in 1960 and 1970. Suburban size is a key characteristic because the independent variables affect black population growth quite differently in different size categories. While there are clear differences between southern and nonsouthern suburbs in average levels of the push and pull variables, as well as the rate at which the black suburban population grew in the 1960s, the effects of these variables on black suburban growth were the same in both regions.     

The Spillover Effects of Restrictive Abortion Laws

Prior research has consistently found that state laws which restrict the access and the availability of abortion services directly reduce abortion demand. This study examines whether these laws also have a spillover effect on abortion demand due to the increase in the price of an abortion that may result from the higher costs imposed on abortion providers as a result of complying with these laws. The empirical results find that the enforcement of a parental notification law and a mandatory counseling law causes an increase in the price charged by abortion providers by over 13% and 9%, respectively. Based on previous estimates of the price elasticity of abortion demand, this implies that the spillover effect of a parental notification law and a mandatory counseling law is to reduce the demand for abortion, through their increase on the price of an abortion, by between 9.4% and 13.6% for a parental notification law and between 6.5% and 9.4% for a mandatory counseling law.

Linearity of the electromechanical penile plethysmograph's output at large expansions

Despite the widespread use of the Barlow‐type electromechanical plethysmograph for monitoring changes in penile circumference, doubts have arisen about its sensitivity at large expansions. This study investigated the linearity of both a used and unused gauge over a wide range of standardized expansions. For both gauges, the relationship between electrical output and physical expansion was almost linear. A logarithmic 10 transformation on the physical expansion data did not for either gauge achieve perfect linearity. Contrary to suggestions in the literature, therefore, such a transformation is not required when using this gauge.     

Core Competencies in Social Constructionist Supervision?

Family therapy is moving increasingly toward evidence‐based practice and competency‐based training. This article explores what might seem to be an unlikely link between social constructionist supervision, which is based on dialogic and fluid processes of meaning‐making, and the increasing reliance on discrete core competencies in the education and training of family therapists. We propose an alternate approach to competencies for supervision with therapists in training that, among other things, invites accountability and provides evaluative props. The approach we propose is based on a set of orientations that we hope reflect the dialogic and contextual nature of social constructionist practice and supervision. These orientations consist of reflexivity and attention to power, fostering polyphony and generativity, collaborative stance, and focus on client resourcefulness. Ideas and questions for supervisors and therapists in training to address the orientations are articulated.     

Rural African American Clergy: An Exploration of Their Attitudes and Knowledge of Alzheimer's Disease

Rural African American clergy's ability to recognize Alzheimer's Disease (AD) and their capacity to provide support to elders with this illness has been neglected in the literature. Using a mental health literacy framework, the purpose of this research was to explore rural African American clergy knowledge and beliefs of AD. In-depth interviews were conducted with 9 African American clergy who oversaw churches in central Kentucky. Although few had direct experience with providing pastoral care to elders with AD, all clergy were literate and aware of the need for additional training. This study seeks to further clarify the role of African American clergy and their understanding of AD to inform the future development of appropriate interventions and establish better collaborative community treatment relationships.     

On the efficiencies of some common quick estimators

The quick estimators of location and scale have broad applications and are widely used. For a variety of symmetric populations we obtain the quantiles and the weights for which the asymptotic variances of the quick estimators are minimum. These optimal quick estimators are then used to obtain the asymptotic relative efficiencies of the commonly used estimators such as trimean. gastwirth. median, midrange. and interquartile range with respect to the optimal quick estimators in order to determine a choice among them and to check whether they are unacceptably poor. In the process it is seen that the interquartile range is the optimal quick estimator of scale for Cauchy populations; but the interdecile range is in general preferable. Also the optimal estimator of the location for the logistic distribution puts weights 0.3 on each of the two quartiles and 0.4 on the median. It is shown that for the symmetric distributions, such as the beta and Tukey- lambda with [d] > 0, which have finite support and short tails, i.e. the tail exponents (Parzen, 1979) satisfy [d] < 1, the midrange and the range are the optimal quick estimators of location and scale respectively if [d] < 1/2. The class of such distributions Include the distributions with high discontinuous tails, e.g. Tukey-lambda with [d] > 1, as well as some distributions with p.d.f.'s going to zero at the ends of the finite support, such as Tukey-lambda with 1/2 < [d] < 1. As a byproduct an interesting tail correspondence between beta and Tukey-lambda distributions is seen.     

Capacity in the NGO Sector: Results from a National Survey in Cambodia

Capacity has become a prominent theme in the literature on nongovernmental organizations (NGOs) in the last few decades, due in part to the increasingly global role these organizations play in development. We analyze data obtained from a national sample of local and international NGOs operating in Cambodia, documenting capacity differences between these two groups as well as highlighting overall levels of capacity in the sector. The analysis covers a number of different organizational dimensions that have been associated with capacity, including structural characteristics and concrete management practices. Results suggest that international NGOs generally have greater capacity, but overall levels of capacity are relatively low for a variety of measures. We conclude with an exploratory cluster analysis that identifies four distinctive groups of NGOs based on capacity, providing additional insights into diversity within the sector. These findings will be useful for comparative NGO research and for capacity-building programs, in addition to helping establish an agenda for future research to monitor progress.     

Crime in Our Cities: A Comparative Study

Crime rates in New South Wales are compared with overseas figures. Comparisons are made between Sydney and eight American and two Canadian cities of similar size. Urban-rural crime rates are studied by relating Sydney, Newcastle and Wollongong to the rest of the State. In both rural and urban areas the rates for homicide, sex offences and other offences against the person are relatively low when compared with American rates. The rates for property offences and car theft are similar to those which exist in America and, and in the case of Sydney, exceed the rate of these offences in the two Canadian cities studied.     

Learning Global Social Conditions: A Broader View for Social Work Students

Today, students are increasingly interested in global issues. To meet this need, social work education must find models to incorporate international content into social work curriculum. This article presents a pedagogical experience to familiarize social work students with comparative social welfare from a global perspective. In a graduate seminar, students utilized data from the United Nations and the World Bank to examine social conditions in different parts of the world in order to gain a broader view of global social conditions. The result was a compilation of profiles highlighting the social conditions of developing countries across different regions of the globe. Furthermore, based on students’ feedback, the benefits of doing such comparative study and the implications for internationalizing social work curriculum are discussed.
