Construct Validation by Hierarchical Bayesian Concept Maps: An Application to the Transaction Cost Economics Theory of the Firm  [PDF]
Matilde Trevisani
Applied Mathematics (AM) , 2017, DOI: 10.4236/am.2017.87079
Abstract: A concept map is a diagram depicting relationships among concepts which is used as a knowledge representation tool in many knowledge domains. In this paper, we build on the modeling framework of Hui et al. (2008) in order to develop a concept map suitable for testing the empirical evidence of theories. We identify a theory by a set of core tenets each asserting that one set of independent variables affects one dependent variable, moreover every variable can have several operational definitions. Data consist of a selected sample of scientific articles from the empirical literature on the theory under investigation. Our “tenet map” features a number of complexities more than the original version. First the links are two-layer: first-layer links connect variables which are related in the test of the theory at issue; second-layer links represent connections which are found statistically significant. Besides, either layer matrix of link-formation probabilities is block-symmetric. In addition to a form of censoring which resembles the Hui et al. pruning step, observed maps are subject to a further censoring related to second-layer links. Still, we perform a full Bayesian analysis instead of adopting the empirical Bayes approach. Lastly, we develop a three-stage model which accounts for dependence either of data or of parameters. The investigation of the empirical support and consensus degree of new economic theories of the firm motivated the proposed methodology. In this paper, the Transaction Cost Economics view is tested by a tenet map analysis. Both the two-stage and the multilevel models identify the same tenets as the most corroborated by empirical evidence though the latter provides a more comprehensive and complex insight of relationships between constructs.
Biopsychosocial perspective of ADHD  [PDF]
Luisa Matilde Salamanca
Open Journal of Epidemiology (OJEpi) , 2014, DOI: 10.4236/ojepi.2014.41001
Abstract: Attention Deficit Hyperactivity Disorder (ADHD) is considered a major public health problem, not only for its high prevalence but also because the symptoms have an impact on activities in daily life at both familial and school levels as well as on a general social level. Clinical evaluation of ADHD was based on the diagnostic criteria of the International Classification of Diseases ICD 10, Diagnostic and Statistical Manual of Mental Disorders DSM IV and comorbidity phenomena. Therefore, it has not yet developed into evaluations any more comprehensive than activity limitations and participation restrictions from a biopsychosocial model of disability, as proposed by the International Classification of Functioning, Disability and Health ICF. Thus, it is necessary to start assessment processes of children with ADHD using the functionality and performance components proposed by the ICF, allowing a new approach and a greater understanding of the health status of this population from a more holistic perspective in relation to the disability. Objective: To identify the theoretical elements that justify the importance of addressing ADHD from a biopsychosocial perspective as proposed by the evaluation of the ICF model, ensuring comprehensive assessment processes. This article is the result of a theoretical review addressed in research projects around the design, validity and reliability of assessment instruments of activity limitations and participation restrictions in children with ADHD.
A Comparison of Hierarchical Bayesian Models for Small Area Estimation of Counts  [PDF]
Matilde Trevisani, Nicola Torelli
Open Journal of Statistics (OJS) , 2017, DOI: 10.4236/ojs.2017.73036
Abstract: Small area estimation (SAE) tackles the problem of providing reliable estimates for small areas, i.e., subsets of the population for which sample information is not sufficient to warrant the use of a direct estimator. Hierarchical Bayesian approach to SAE problems offers several advantages over traditional SAE models including the ability of appropriately accounting for the type of surveyed variable. In this paper, a number of model specifications for estimating small area counts are discussed and their relative merits are illustrated. We conducted a simulation study by reproducing in a simplified form the Italian Labour Force Survey and taking the Local Labor Markets as target areas. Simulated data were generated by assuming population characteristics of interest as well as survey sampling design as known. In one set of experiments, numbers of employment/unemployment from census data were utilized, in others population characteristics were varied. Results show persistent model failures for some standard Fay-Herriot specifications and for generalized linear Poisson models with (log-)normal sampling stage, whilst either unmatched or nonnormal sampling stage models get the best performance in terms of bias, accuracy and reliability. Though, the study also found that any model noticeably improves on its performance by letting sampling variances be stochastically determined rather than assumed as known as is the general practice. Moreover, we address the issue of model determination to point out limits and possible deceptions of commonly used criteria for model selection and checking in SAE context.
Enfoque teórico y conceptual para el estudio de las urbanizaciones cerradas
Malizia,Matilde;
Andes , 2011,
Abstract: this paper presents a theoretical and conceptual approach to the study of gated communities in secondary cities. in latin america, in the first place, urban research focused on large cities and the phenomena resulting from the current process of urbanization. therefore, there is limited information available for the study of gated communities in smaller cities. through literature it is possible to observe that gated communities acquire their own specificity in intermediate cities. they are located on the suburbs, close to parks with good environmental and landscape conditions and promote the development and improvement of infrastructure services. they also modify the processes of social segregation and spatial fragmentation, according to current urban processes. physical barriers become social barriers and cause important differences between "those living inside" and "those who live outside" the gated communities. finally, this kind of communitites occupy smaller areas compared to the extensions of gated communities in large cities, a situation which, in turn, limits the size of the spaces provided.

Abstract: the article "black women: a trajectory of creativity, determination and organization" seeks to make a brief account, focusing on the process of black women's organization in dialogue with the following: the inclusion of gender and race in public policies; the holding of international conferences - in particular, the world conference on women and the 3rd world conference against racism, racial discrimination, xenophobia and related intolerance; the post-durban period: action and monitoring; and the 120 years since the abolition of slavery. lastly, some challenges are formulated as to the struggle for equality and social justice.
O feminismo em novas rotas e vis?es
Ribeiro, Matilde;
Revista Estudos Feministas , 2006, DOI: 10.1590/S0104-026X2006000300012
Abstract: this paper is based on the debate proposed by mary hawkesworth in "the semiotics of a premature burial: feminism in a post-feminist age". it is guided by a latin-american and caribbean view of the transformations of feminism and of women's achievements in critical moments of that articulation, recollecting outstanding periods such as the renovation of feminist ideals; the autonomy of the black women's movement and its inter-relation with black and feminist activism; and international articulations tuned with brazilian reality/diversity and with the incorporation of the feminist agenda within governmental instances. the author portrays how the verve and retro-feeding capacity of brazilian feminism provide the necessary strength for its survival, as well as for its innovations which are consonant with the evolution of social values, leading to its various achievements as they stem from local, regional and global arenas. substantially, the author has developed this text with a sharp focus on local activism as the trigger for effective governmental action towards achieving gender and race equity.
