Horizontal inequity comparisons

In this paper, we expound the idea that horizontal inequity (HI) in different tax systems be compared by transplanting the HI from one tax system into the other, as a mapping between its pre- and post-tax living standard distributions, and then applying known results to compare the extent of association present in the two joint distributions. We make this idea operational by means of axioms which, we show, lead to an implementable procedure based on the `copula'. Statistical inference procedures are discussed, and illustrative empirical exercises are undertaken for the UK, Canadian and Israeli tax and benefit systems.

Matrimonial Transactions and the Enactment of Class and Gender Difference Among Egyptian Youth

The literature from the Middle East and North Africa holds that many youth get stuck in a phase of “wait adulthood” while they struggle to afford the housing, furniture, appliances, celebrations, and jewelry considered necessary to establish a new marital union. In semi-structured interviews with 66 urban Egyptian men and women who were engaged to be married, I found that many marriages were postponed when young couples were unable to make the matrimonial transactions required by custom. However, I argue that normative barriers are no less important than material barriers to marriage in this context. Matrimonial transactions could not be reduced or forgone because they communicated important meanings related to class and gender. The celebrations and home visits that accompanied a new union involved conspicuous consumption, and actors strove to reproduce the material behaviors that predominated in their social class in order to secure a favorable position in the hierarchy of new couples. Matrimonial transactions were sharply gendered, and adherence to matrimonial norms and the ritualized situations that came with them signaled actors’ dedication to ideals of masculinity and femininity and the unequal roles they would occupy within marriage, at the same time that matrimonial exchanges built in safeguards for women within marriage. Young couples were keenly aware that failure to live up to the material standards of their social circles would be met with loss of face and negative judgements about their personal qualities, making such outlays appear to be compulsory rather than optional. At the same time, conforming to matrimonial customs resulted in greater symbolic capital, or social prestige.     

A Dominance-Based Rough Set Approach for an Enhanced Assessment of Seasonal Influenza Risk

Accounting for about 290,000–650,000 deaths across the globe, seasonal influenza is estimated by the World Health Organization to be a major cause of mortality. Hence, there is a need for a reliable and robust epidemiological surveillance decision-making system to understand and combat this epidemic disease. In a previous study, the authors proposed a decision support system to fight against seasonal influenza. This system is composed of three subsystems: (i) modeling and simulation, (ii) data warehousing, and (iii) analysis. The analysis subsystem relies on spatial online analytical processing (S-OLAP) technology. Although the S-OLAP technology is useful in analyzing multidimensional spatial data sets, it cannot take into account the inherent multicriteria nature of seasonal influenza risk assessment by itself. Therefore, the objective of this article is to extend the existing decision support system by adding advanced multicriteria analysis capabilities for enhanced seasonal influenza risk assessment and monitoring. Bearing in mind the characteristics of the decision problem considered in this article, a well-known multicriteria classification method, the dominance-based rough set approach (DRSA), was selected to boost the existing decision support system. Combining the S-OLAP technology and the multicriteria classification method DRSA in the same decision support system will largely improve and extend the scope of analysis capabilities. The extended decision support system has been validated by its application to assess seasonal influenza risk in the northwest region of Algeria.     

Use of a Modified Chaining Procedure with Textual Prompts to Establish Intraverbal Storytelling

Echoic, tact, and textual transfer procedures have been proven successful in establishing simple intraverbals (Braam and Poling Applied Research in Mental Retardation, 4, 279–302, 1983; Luciano Applied Research in Mental Retardation, 102, 346–357, 1986; Watkins et al. The Analysis of Verbal Behavior, 7, 69–81, 1989). However, these strategies may be ineffective for some children due to the complexity of the targeted intraverbals. The current study investigated the use of a novel procedure which included a modified chaining procedure and textual prompts to establish intraverbal behavior in the form of telling short stories. Visual prompts and rule statements were used with some of the participants in order to produce the desired behavior change. Results indicated that the procedure was effective for teaching retelling of short stories in three children with autism.     

A Discrepancy Index for the Study of Participation with an Application to the Case of Higher Education in Italy

This article proposes and applies a simple method to measure the distance from a situation of uniform participation. First, a discrepancy index based on the use of generalized Lorenz curves is presented. This index can be expressed in terms of means and Gini indices of relevant characteristics in the populations of participants and that of a control group. A multivariate extension is also illustrated. The discrepancy index is then used to analyse access into higher education in Italy during the nineties. Discrepancy between participants and non-participants is especially high in terms of parents’ wealth and education, less in terms of income. Also, discrepancy is higher during recessions. Multivariate analysis reveals that “cultural constrains” are more important than financial constraints. Hence, efforts to equalize opportunity for access into higher education should be as much focussed on motivation and social background as they are on financial constraints.

Outcomes of a model care coordination program for adults with mental illness under guardianship/conservatorship

Adults with serious and persistent mental illnesses, such as schizophrenia, schizoaffective disorder, and bipolar disorder, who are under guardianship/conservatorship, may experience health care, social, financial, and housing concerns, which can be addressed by care coordination programs. In such programs, providers assist with communication across service sectors, assistance with monitoring of psychiatric care, and support with practical needs. Such programs are understudied in the context of guardianship/conservatorship. Through a review of electronic records for 217 consumers who were enrolled in a model program continuously for 3 years or more, we examined trends before and after enrollment in a model care coordination program for adults with serious and persistent mental illnesses under guardianship/conservatorship. We sought to describe the number of days and rates of hospitalization, emergency room visits, and arrests before and after receiving program services. Comparing utilization among consumers three years pre- to three years post-enrollment, we identified statistically significant reductions in hospitalizations and imprisonment, but no change in state hospitalizations. We also saw some (non-significant) reduction in emergency room visits. Findings provide preliminary evidence of effectiveness of the model program; future efforts could expand its reach to more adults with serious and persistent mental illnesses.     

Mands for Information Using “How” Under EO-Absent and EO-Present Conditions

The present study replicates and extends previous research on teaching “How?” mands for information to children with autism. The experimental preparation involved mand training in the context of completing preferred activities and included training and testing under conditions when the establishing operation (EO) was present and absent. Results show that two children with autism acquired mands for information using How? only in situations where information was valuable (i.e., the EO was present); they then consistently made use of the information provided in activity completion. Generalization to novel, untaught situations was assessed.
