Tests for Cointegration Breakdown Over a Short Time Period

We derive a speculative trading model with endogenous informed trading that yields a conditionally heteroscedastic time series for trading volume and the squared price changes. We use half-hourly price-change and volume data for IBM during 1988 to test the model and estimate the structural parameters using the simulated method-of-moments estimation procedure. Although the model seems to do a reasonable job fitting the unconditional moments of the volume and the squared price change processes, it fares less well in fitting the relation between current trading volume and lags of trading volume and squared volume's (and its lag's) relation to squared price changes.     

ASA certification as cooptation

We provide a brief overview of the American Sociological Association’s Ph.D. Certification Program and question the need for, and justification of, certifying sociologists. Essentially, the ASA certification mechanism, as implemented, is nonsociological, emphasizing presumed defects in the individual to the neglect of wider, systemic forces impinging on our discipline. If certification of sociologists is warranted, a view difficult to support given the small number of applicants for certification since 1986, we suggest departmental accreditation—a more sociological approach that emphasizes the value of the discipline, in and of itself. His research interests include political sociology, stratification and contemporary issues affecting the discipline. His research foci include rural and agricultural issues and the sociological employment market and profession.     

Reflections of a Group of Deaf Adults on Their Experiences in Mainstream and Residential School Programs in the United States

The purpose of this study was to learn about mainstream and residential school programs for deaf students in the United States from the perspective of the deaf person, and to present the experiences of clients of educational services in their own words. Data for this paper were collected through open-ended, in-depth interviews with 25 graduates from the National Technical Institute for the Deaf at Rochester Institute of Technology (NTID at RIT). The comments of informants suggest that there are advantages and disadvantages inherent in each educational model. For example, the selection of one model over another may involve 'trading' academic for social opportunity. In particular, it is suggested that both kinds of school experiences play a critical role in the socialization of deaf people and the development of deaf community. It is recommended that further research be conducted to learn more about the perspectives of deaf people on educational services and to explore with them the long term as well as the immediate impact of different kinds of school environments.     

Parenthood and Marital Satisfaction: A Meta‐Analytic Review

This meta‐analysis finds that parents report lower marital satisfaction compared with nonparents (d=?.19, r=?.10). There is also a significant negative correlation between marital satisfaction and number of children (d=?.13, r=?.06). The difference in marital satisfaction is most pronounced among mothers of infants (38% of mothers of infants have high marital satisfaction, compared with 62% of childless women). For men, the effect remains similar across ages of children. The effect of parenthood on marital satisfaction is more negative among high socioeconomic groups, younger birth cohorts, and in more recent years. The data suggest that marital satisfaction decreases after the birth of a child due to role conflicts and restriction of freedom.

Sonet-1: Social network analysis and modeling system

SONET-I is a preliminary but completely operational version of a package of computer programs for the analysis of social structure. The programs were written to implement a strategy for the analysis of social networks which the authors have developed over the past several years. The conceptual basis for the research method has its origins in graph theory on the one hand and in anthropological studies of social organization — especially kinship studies — on the other. The method can, in fact, be seen as a graph theoretic formalization and generalization of kinship-based methods of social analysis often associated with British social anthropology.     

Clinical social work education in palliative and end-of-life care: relational approaches for advanced practitioners

This paper describes the first post-Master's program in the US in end-of-life care for social workers. Developed at the Smith College School for Social Work, this program used innovative relational methods in student recruitment, curricular design, supervision, and leadership development, based upon input from the faculty, students, and field supervisors. Collaborations emerged with funders, agencies, and programs nationally. The program was based on a pedagogical stance that clinical work with dying people requires the capacity to be fully present- in individual, group, and family work; in interdisciplinary meetings; and in advocating for quality and equity of care-while attending to diverse and at-risk populations. Students deepened their clinical skills and took leadership in the field of end-of-life care.     

Dynamic Savings Decisions in Agricultural Environments With Incomplete Markets

We develop a methodology for examining savings behavior in rural areas of developing countries that explicitly incorporates the sequential decision process in agriculture. The approach is used to examine the relative importance of alternative forms of savings in the presence and absence of formal financial intermediaries. Our results, based on stage-specific panel data from Pakistan, provide evidence that the presence of financial intermediaries importantly influences the use of formal savings and transfers for income smoothing. We also find that there are significant biases in evaluations of the savings-income relationship that are inattentive to the within-year dynamics of agricultural production.
