Gramatica de la Mente y Conocimiento Tacito

Resumen

Este artículo se ha centrado en las limitaciones que han encontrado los intentos de construir modelos formales del conocimiento humano y en el significado de dichas limitaciones. Se ha argumentado que dichas limitaciones tienen su origen en el hecho de que las reglas que constituyen la gramática de la mente son reglas sensibles a los contextos, en oposición a puramente formales.

Todo ello nos ha llevado ha exponer la tesis de que en el mundo social el conocimiento existe encarnado en individuos, pero no puede ser explicado desde el individuo, requiere un marco social. Y si esto es así, la Psicología cognitiva debe ser reinterpretada como psicología social del conocimiento.

Nuestra apuesta personal es que el desarrollo futuro de esta posición será tanto más prometedor cuanto más uso sepa hacer de lo que ya empieza a ser llamado “Epistemología de la complejidad” (véase Jantsch, 1981; Guidano, en prensa; Ibáñez, 1986; Miró en prensa, b). El desarrollo de este reto, sin embargo, pertenece todavía al futuro de la investigación.     

Much Ado About Nothing?

We can only welcome the discourse that has been initiated in our professional community with the concept of public sociology in the focus. Undoubtedly, Michael Burawoy has indisputable merits in fuelling this international dialogue. I find, however, that his position and conceptual framework is debatable at several points, therefore my review is on the side of those who criticize his ideas. My paper is divided into three parts: in keeping with the idea that the drop mirrors the ocean, I will start with the detailed critique of a single paragraph—the one which makes comments on his table entitled Types of sociological knowledge. It will be argued that by switching his viewpoints and using vaguely defined notions without empirical evidences he often tackles his subject inconsistently. Secondly, I intend to offer an alternative, three-dimensional conceptual model in which the social scientist’s prestige, influence and position on the action chain is taken into account as the main analytical aspects of the relationship between her/him and the public. Finally, based on this model, I propose to identify some strategies in order to find a better balance between the public and professional activity of social scientists.     

The satisfaction of Finnish adoptive parents with statutory pre-adoption counselling in inter-country adoptions

We examined how satisfied Finnish adoptive parents were with statutory pre-adoption counselling in inter-country adoptions. The data were collected through the Finnish Adoption Study using a retrospective survey measuring satisfaction with received pre-adoption counselling. All adoptive parents with a child under the age of 18, adopted from abroad between the years 1990 and 2007, were included. The sample of the study comprised parents of 1451 children and a total response rate of 55.7% was achieved. The data consisted of self-scored reports of satisfaction as well as open answer questions. Parent satisfaction and associated variables were analysed using chi-square and multiple logistic regression. Of the respondents, 81.7% reported satisfaction with the pre-adoption counselling they had received. The level of satisfaction was stable over time and did not differ according to service provider, whereas family type and sending country were associated with satisfaction. However the explanations for satisfaction were different for those services provided in units specialized in adoption and for those provided by municipal child protection services. The components found to explain satisfaction and dissatisfaction were experience, adoption knowledge, and attitude of the social worker, service accessibility and availability issues, as well as the content of the pre-adoption counselling offered.     

Regression Methods for Combining Multiple Classifiers

As no single classification method outperforms other classification methods under all circumstances, decision-makers may solve a classification problem using several classification methods and examine their performance for classification purposes in the learning set. Based on this performance, better classification methods might be adopted and poor methods might be avoided. However, which single classification method is the best to predict the classification of new observations is still not clear, especially when some methods offer similar classification performance in the learning set. In this article we present various regression and classical methods, which combine several classification methods to predict the classification of new observations. The quality of the combined classifiers is examined on some real data. Nonparametric regression is the best method of combining classifiers.
