On the diversity score: a copula approach

ABSTRACT

For the rating process of Collateralized Debt Obligations', Moody's suggests the Diversity Score as a measure of diversification in the collateral pool. This measure is used in Moody's Binomial Expansion Technique to infer the probability of default and thus the expected Loss in the portfolio. In this paper, we examine the appropriateness of this approach to assess the reality of defaults using a copula approach and lower tail dependence.     

New evidence on the fertility transition in Ireland 1880–1911

Understanding Multiple Group Identities: Inserting Women into Cultural Transformations

The study of cultural transformations in the United States has been studied predominantly from an assimilation/acculturation framework. There are several drawbacks to this theoretical perspective, chief among them being the exclusion of gender in examining what happens to different ethnic/racial groups when they come into contact. Feminist writings in the last twenty years provide a rich discussion of how inserting women into this social process would enrich our knowledge about human behavior in general and cultural change specifically. This paper reviews the literature on the assimilation/acculturation framework and integrates the most recent developments in feminist theory to provide a new alternative to studying cultural transformations. The social engagement model takes into account gender as well as other significant social identities like ethnicity/race, class, and sexuality to study how groups change as they come into contact with each other.     

Early Intervention in Portugal: Study of Professionals’ Perceptions

Early intervention (EI) has been characterized by considerable advances in its domain, which has had great repercussions in the implementation of the family-centered approach. These changes have had implications in the practices and in the adoption and learning of new values that should be implemented in EI. This study evaluates the professional perspectives regarding family-centered practices in EI programs in Portugal. The results highlight the importance of effective collaboration and coordination between health, education, and social services and the importance of providing child and family support in a natural context. These results reinforce the need to invest in professional training to improve the quality of services offered to families in EI.
