A note on closure of the ILR and DLR classes under formation of coherent systems

In this paper, we give the closure of the class of increasing likelihood ratio (ILR) life distributions under the formation of certain coherent systems with independent and identically distributed components, and particularly in k-out-of-n systems. Some possible definitions of its dual class (DLR) are discussed and results about the closure are given. Furthermore, we include examples which show that these two aging classes are not closed under formation of special coherent systems.

Persephone today: Use of dreams imagery,and myth in the treatment of raped women

Therapists today are seeing an increasing number of victims of rape. The article deals with the on-going psychotherapy of raped women; the impact the presenting problem has on both client and therapist; and some ways forms of imagery. The meaning of the myth is explored within the context of the author's experience with these women.     

THE FEMALE VOICE: APPLICATIONS TO BOWEN'S FAMILY SYSTEMS THEORY

This paper is written in response to calls from feminist scholars to address potential biases against women in theories of family therapy. Findings from studies offemale development are summarized and integrated into an expanded model of Bowen's family systems theory. A case example comparing the expanded model with a traditional application of Bowen's theory is included.     

Balanced allocation methods for claims problems with indivisibilities

We study claims problems in which a certain amount of indivisible units (of an homogeneous good) has to be distributed among a group of agents, when this amount is not enough to fully satisfy agents’ demands. Our aim is to find solutions fulfilling procedural and fairness properties. To do that, we define the M-down methods, which are the unique robust (composition down and consistency) and fair (balancedness and conditional full compensation) rules. Besides, we also establish the relationship between these M-down methods and the constrained equal awards rule.     

Reducing transfers of children in family foster care through onsite mental health interventions

This article describes a successful pilot project in New York City that effectively reduced the number of transfers or replacements of children in family foster care through the placement of mental health clinicians onsite at two foster care agencies.     

Social well-being in pregnant women: intended versus unintended pregnancies

The relationship between pregnancy intention (unintended versus intended pregnancy) and social well-being was examined in a sample of 72 pregnant, mostly low-income women attending Women, Infants, and Children programs and prenatal clinics in a midwestern community. Feelings of happiness about giving birth and the extent to which having a baby would fill a void in one's life were also examined. Pregnancy intention was significantly associated with reduced social support. Feelings of happiness about having the baby positively correlated with all domains of social support and negatively correlated with loneliness and family relationship problems. The belief that having a baby could fill a void in a woman's life was strongly correlated with perceived loneliness. Interventions to increase social support and to address areas of stress for women whose pregnancies are unintended are recommended. Future research in larger random samples is needed to better test these associations and to make recommendations for specific practice interventions to increase social well-being.     

Letter to the Editor: Respecting Multiple Epistemologies in Social Work

The Making of Vulnerabilities: Indigenous Day Laborers in Mexico's Neoliberal Agriculture

This article explores the linkages between representations of race, culture, and social structure in the San Quint’n Valley, Baja California, an area of northwestern Mexico that produces tomatoes for export to the United States using an indigenous migrant labor force. I focus on a day laborers' riot that took place in 1996. The press debate that followed the event exposed the articulation between local cultural images, social relations, and global political-economic processes. I argue that the modern agro-export sector takes advantage of and reshapes colonial and postcolonial caste-based social relations that are most likely associated with "tradition." The use of indigenous day laborers in segmented labor markets typical of "flexible capitalism" is interpreted locally as a return to the past. Contract farming, an arrangement between Mexican entrepreneurs and transnational corporations, creates some confusion. Some blame Mexican caciques (ruthless landowners), whereas others blame transnational firms for the exploitation of indigenous peasants. Those who blame caciques evoke images of backward Latin American regions that need to be modernized by the revolutionary state. Those who hold global corporations responsible interpret neoliberal agriculture as a return to the nineteenth-century Porfiriato, a period of foreign capital penetration in Mexico. Paradoxically, "modernity" is associated with revolutionary social justice as the ideals and values of the Mexican Revolution are being radically reworked by the introduction of neoliberal policies.

Resumen

Hemos realizado un estudio diferencial sobre las interpretaciones causales y sus consecuencias cognitivo- afectivas en un contexto de robo, utilizando como marco teórico el último modelo atribucional de Weiner (1986). Para ello, hemos aplicado cuestionarios de autoinforme a 1.450 sujetos menores de edad. Los resultados, obtenidos mediante análisis de la varianza y técnicas de regresión, indican (1) que existe una taxonomía de las causas claramente diferenciada en función de las dimensiones—locus, estabilidad y controlabilidad—, y de la perspectiva—actor/observador—de los sujetos; (2) que la estabilidad de las causas determina la predicción de reincidencia, y que ésta es mayor en los sujetos que dicen haber cometido más robos, y (3) que el sentimiento de culpa está determinado por la controlabilidad de las causas y varía como función inversa de la experiencia delictiva. Finalmente, señalamos algunas implicaciones teóricas y aplicadas de este trabajo.
