Assessing the relationship between board composition and nonprofit hospital financial performance from a multi-theoretic perspective

This dissertation assesses the relationship between board composition and financial performance for the top 71 major nonprofit hospitals in the United States during the period 2004-2009. The underlying data were collected from copies of IRS Form 990 available at http://www.guidestar.org . The dissertation investigates five factors: board size, board independence (percentage of outsiders), number of MDs, CEO succession and CEO compensation. And it evaluates the results within a multi-theoretic framework drawing on agency theory, resource dependence theory, institutional theory and social network theory. Corporate governance literature suggests that board composition has an important impact on firm financial performance. This dissertation examines whether the same may be true for nonprofit hospitals. The results should help hospital executives make better governance decisions during trying economic times.^

Risk and protective factors associated with depression among racial and ethnic mothers of adolescents

The central paradigm linking disadvantaged social status and mental health has been the social stress model (Horwitz, 1999), the assumption being that individuals residing in lower social status groups are subjected to greater levels of stress not experienced by individuals from higher status groups. A further assumption is that such individuals have fewer resources to cope with stress, in turn leading to higher levels of psychological disorder, including depression (Pearlin, 1989). Despite these key assumptions, there is a dearth of literature comparing the social patterning of stress exposure (Hatch & Dohrenwend, 2007; Meyer, Schwartz, & Frost, 2008; Kessler, Mickelson, & Williams, 1999; Turner & Avison, 2003; Turner & Lloyd, 1999; Turner, Wheaton, & Lloyd, 1995), and the distribution and contribution of protective factors, posited to play a role in the low rates of depression found among African- and Latino-Americans (Alegria et al., 2007; Breslau, Aguilar-Gaxiola, Kendler, Su, Williams, & Kessler, 2006; Breslau, Borges, Hagar, Tancredi, Gilman, 2009; Gavin, Walton, Chae, Alegria, Jackson, & Takeuchi, 2010; Williams, & Neighbors, 2006). Thus, this study sought to describe both the distribution and contribution of risk and protective factors in relation to depression among a sample of African-, European-, and Latina-American mothers of adolescents, including testing a hypothesized mechanism through which social support, an important protective factor specific to women and depression, operates. ^ Despite the finding that the levels of depression were not statistically different across all three groups of women, surprising results were found in describing the distribution of both risk and protective factors, in that results reported among all women who were mothers when analyzed masked differences within each ethnic group when SES was assessed, a point made explicit by Williams (2002) regarding racial and ethnic variations in women's health. In the final analysis, while perceived social support was found to partially mediate the effect of social isolation on depression, among African-Americans, the direct effect of social isolation and depression was lower among this group of women, as was the indirect effect of social isolation and perceived social support when compared to European- and Latina-American mothers. Or, put differently, higher levels of social isolation were not found to be as associated with more depression or lower social support among African-American mothers when compared to their European- and Latina-American counterparts. ^ Women in American society occupy a number of roles, i.e., that of being female, married or single, mother, homemaker or employee. In addition, to these roles, ethnicity and SES also come into play, such that the intersection of all these roles and the social contexts that they occupy are equally important and must be taken into consideration when making predictions drawn from the social stress model. Based on these findings, it appears that the assumptions of the social stress model need to be revisited to include the variety of roles that intersect among individuals from differing social groups. More specifically, among women who are mothers and occupy a myriad of other roles, i.e., that of being female, married or single, African- or Latina-American, mother, homemaker or employee, the intersection of all the roles and the social contexts that women occupy are equally important and must be taken into consideration when looking at both the types and distribution of stressors across women. Predictions based on simple, mutually exclusive categories of social groups may lead to erroneous assumptions and misleading results.^

Attitudes of health-care workers toward pregnant, HIV -positive women

The management of HIV infection with antiretroviral drugs has succeeded in increasing survival rates, but the subject of pregnancy in HIV-positive women continues to garner debate. Discrimination and stigma have been identified as barriers to health care, suggesting that women with HIV may be disinclined to seek prenatal care if health-care workers exhibit negative attitudes toward the women's pregnancies. To optimize prenatal and medical care for women with HIV infection, it is important to understand the general social conditions and cultural context in which these women have children. Goffman's treatise on stigma, Foucault's discussion of the knowledge/power matrix, and Bandura's Social Cognitive Theory offer theoretical perspectives by which we can evaluate the gender, race, and class issues that are inherent in pregnancy decision-making for women with HIV infection. It is also necessary to evaluate prevailing attitudes on childbearing toward HIV-positive women and to review the historical background of prejudice in which HIV-positive women make decisions regarding childbearing. ^ This qualitative study used a survey instrument and one-on-one interviews with HIV-infected women to elicit their perceptions of how they were treated by care providers when they became pregnant. It also included interviews with health-care workers to determine what their feelings are about pregnancy within the context of HIV infection. Results of the ethnographic inquiry reveal that most of the women had negative experiences at some point during a pregnancy, but that the situation improved when they sought care from a provider who was familiar with HIV infection. The health-care providers interviewed were firm in their belief that HIV-positive women deserved optimal care and treated the women with respect, but these are individuals who are also experts in providing care to HIV-positive patients. The question remains as to what kind of care HIV-positive women are receiving generally and what types of attitudes they are being subjected to if they see less experienced providers. Further research is also needed to determine whether HIV-positive women from a broader ethnic representation and higher socioeconomic status experience similar negative attitudes. ^

La educación, base para el desarrollo y la seguridad a escala humana

Las teorías sobre el desarrollo son en realidad un dinámico debate acerca de la relación población/recursos, de las condiciones de inequidad a escala planetaria y al interior de las naciones, y de las formas de superarlas. Para avanzar hacia el desarrollo humano, es prioritario enfocar las acciones en la superación de las carencias que afectan la situación personal de los ciudadanos y eliminar los obstáculos que impiden su bienestar en relación con las condiciones medioambientales en las que transcurre su vida. La educación es comprendida como el eje fundamental para alcanzar niveles de desarrollo aceptables, asegurando superar situaciones de exclusión social. Sobre la base de encuestas en cuatro establecimientos educativos del Gran Mendoza, se analizan las relaciones existentes entre las representaciones, de los adolescentes y sus familias sobre la importancia de la educación como medio optimizador de las situaciones socioeconómicas y los proyectos de capacitación futura, tanto a nivel terciario como universitario.

¿Por qué marchar el 24 de marzo? : juventud, memoria y participación política en Mendoza

La movilización del 24 de marzo, aniversario del último golpe de Estado en la Argentina, ha adquirido enorme relevancia política a lo largo del tiempo. Este espacio de participación y acción conjunta, resulta un ámbito pertinente para indagar la elaboración de una memoria colectiva sobre el pasado reciente y su impacto en las primeras generaciones de jóvenes que no vivieron la época de la dictadura en forma directa. La caracterización sobre el pasado, conlleva visiones sobre el presente y condiciona modos de intervención en la realidad social. El trabajo que se presenta, fue realizado en base a estrategias cualitativas de investigación social, a partir de entrevistas y observaciones en la provincia de Mendoza.

Hiord: A type-free higher-order logic programming language with predicate abstraction

A new formalism, called Hiord, for defining type-free higherorder logic programming languages with predicate abstraction is introduced. A model theory, based on partial combinatory algebras, is presented, with respect to which the formalism is shown sound. A programming language built on a subset of Hiord, and its implementation are discussed. A new proposal for defining modules in this framework is considered, along with several examples.

Artificial metaplasticity prediction model for cognitive rehabilitation outcome in acquired brain injury patients

Objective The main purpose of this research is the novel use of artificial metaplasticity on multilayer perceptron (AMMLP) as a data mining tool for prediction the outcome of patients with acquired brain injury (ABI) after cognitive rehabilitation. The final goal aims at increasing knowledge in the field of rehabilitation theory based on cognitive affectation. Methods and materials The data set used in this study contains records belonging to 123 ABI patients with moderate to severe cognitive affectation (according to Glasgow Coma Scale) that underwent rehabilitation at Institut Guttmann Neurorehabilitation Hospital (IG) using the tele-rehabilitation platform PREVIRNEC©. The variables included in the analysis comprise the neuropsychological initial evaluation of the patient (cognitive affectation profile), the results of the rehabilitation tasks performed by the patient in PREVIRNEC© and the outcome of the patient after a 3–5 months treatment. To achieve the treatment outcome prediction, we apply and compare three different data mining techniques: the AMMLP model, a backpropagation neural network (BPNN) and a C4.5 decision tree. Results The prediction performance of the models was measured by ten-fold cross validation and several architectures were tested. The results obtained by the AMMLP model are clearly superior, with an average predictive performance of 91.56%. BPNN and C4.5 models have a prediction average accuracy of 80.18% and 89.91% respectively. The best single AMMLP model provided a specificity of 92.38%, a sensitivity of 91.76% and a prediction accuracy of 92.07%. Conclusions The proposed prediction model presented in this study allows to increase the knowledge about the contributing factors of an ABI patient recovery and to estimate treatment efficacy in individual patients. The ability to predict treatment outcomes may provide new insights toward improving effectiveness and creating personalized therapeutic interventions based on clinical evidence.

A holistic experience in the integrated learning of specialized English and content in Engineering degrees

This paper aims to outline a theory-based Content and Language Integrated Learning course and to establish the rationale for adopting a holistic approach to the teaching of languages in tertiary education. Our work focuses on the interdependence between Content and Language Integrated Learning (CLIL), and the use of Information and Communication Technologies (ICT), in particular regarding the learning of English within the framework of Telecommunications Engineering. The study first analyses the diverse components of the instructional approach and the extent to which this approach interrelates with technologies within the context of what we have defined as a holistic experience, since it also aims to develop a set of generic competences or transferable skills. Second, an example of a course project framed in this holistic approach is described in order to exemplify the specific actions suggested for learner autonomy and CLIL. The approach provides both an adequate framework as well as the conditions needed to carry out a lifelong learning experience within our context, a Spanish School of Engineering. In addition to specialized language and content, the approach integrates the learning of skills and capacities required by the new plans that have been established following the Bologna Declaration in 1999.

Planning and projects: three visionaires Friedmann, J., Trueba, I. and Ramos, A.

It is impossible to talk about planning as a scientific meta-discipline without mentioning one of the most influential worldwide figures in the second half of the twentieth century: John Friedmann. His contribution to the planning concept on his "Planning as Social Learning" theory is still very relevant. This paper shows the intellectual connection between Friedmann and Angel Ramos and Ignacio Trueba, two of the Spanish intellectual drivers in the engineering project knowledge area, who contributed to founding the Engineering Projects Spanish Association. The three of them share a broad vision of the project and abandon the "blue print" planning model. They also see the project as a transformational tool that requires a different planning style to the one which prevailed in the 70s - both in public and private domains. They were pioneers in structuring Knowledge / Action in a different way, both in academic institutions where disciples helped to bring about change- and with direct action via projects.

DROGAS E ALUNOS USUÁRIOS DE DROGAS NA ESCOLA: ESTUDO DE REPRESENTAÇÕES SOCIAIS DE PROFESSORES DO ENSINO MÉDIO DA REDE ESTADUAL DE SÃO PAULO

Este estudo apresenta uma discussão a respeito de drogas e de alunos usuários de drogas na escola, explorando as Representações Sociais manifestadas por professores que atuam na Rede Estadual de São Paulo, no ensino Médio. O estudo resgata aspectos históricos e sociais que influenciaram representações sociais sobre drogas em diferentes contextos da sociedade, na perspectiva de buscar compreender a maneira como atualmente elas se apresentam. Discute aspectos conceituais da Teoria das Representações Sociais a partir de Moscovici, considerando contribuições de Jodelet, e outros autores. Os dados coletados por meio de questionários e entrevistas foram analisados com o auxílio de dois softwares, o ALCESTE para análise lexical e o EVOC para análise de associação de palavras ou expressões, em articulação com uma análise de conteúdo clássica sugerida por Maria Laura Puglisi Barbosa Franco. O resultado identificou que as representações sociais sobre drogas na escola e alunos usuários estão ancoradas no modo como a grande mídia trata o tema, de forma alarmista e sensacionalista, influenciando grande parte dos professores que associa drogas na escola à violência. Verificou-se ainda que objetivação do aluno usuário de drogas é simbolizada como doença e que o grupo pesquisado segue as representações sociais há muito tempo estruturadas na sociedade, tendo a normalidade como sinônimo de saúde e a drogadição como condição desviante, decorrente de patologias. Assim, espera-se estar contribuindo para a reflexão sobre o uso e abuso de drogas nas escolas, um tema indispensável e que precisa ser enfrentado para construir-se uma via que leve a uma Educação justa e democrática.(AU)

“Coarse” stability and bifurcation analysis using time-steppers: A reaction-diffusion example

Evolutionary, pattern forming partial differential equations (PDEs) are often derived as limiting descriptions of microscopic, kinetic theory-based models of molecular processes (e.g., reaction and diffusion). The PDE dynamic behavior can be probed through direct simulation (time integration) or, more systematically, through stability/bifurcation calculations; time-stepper-based approaches, like the Recursive Projection Method [Shroff, G. M. & Keller, H. B. (1993) SIAM J. Numer. Anal. 30, 1099–1120] provide an attractive framework for the latter. We demonstrate an adaptation of this approach that allows for a direct, effective (“coarse”) bifurcation analysis of microscopic, kinetic-based models; this is illustrated through a comparative study of the FitzHugh-Nagumo PDE and of a corresponding Lattice–Boltzmann model.
