Las políticas de ciencia y tecnología en Venezuela y su impacto en el sistema universitario en el estado Zulia
Parra,María Cristina;
Interciencia , 2007,
Abstract: the policies of science and technology developed by the venezuelan state have been tacitly oriented to surpass the traditional model of production of the knowledge. the unexpected effects of those policies indicate that this model has been strengthened: individualism, isolation, low pertinence and specialization inhibit new models of research. traditionally, the scientific production has had its privileged space in the universities and in them the professors have the key paper in the knowledge production. in the article it is analyzed the possible effect that the policies implemented by the state have had in the reinforcement of a model of production of the knowledge that does not go beyond the academic realm, nor implies the companies, the nongovernmental organizations and communities of direct way. data obtained from a sample of professors of four universities of the zulia region is analyzed: two public institutions and two private ones. the analysis inquires the policies of science and technology of the venezuelan state and challenges to the university institutions and to the own state to evaluate which is the true social impact that the policies have had and to what extent they have meant the democratization of the knowledge.
Desarrollos del analisis factorial para el estudio de item dicotomicos y ordinales
Richaud,María Cristina;
Interdisciplinaria , 2005,
Abstract: factor analysis has been used in formulating conceptual models in personality and personality assessment, as well as in the process of construction of personality scales. factor analysis assumes continuously measured interval level data. however, applications of the factor analysis model in the personality literature frequently are conducted using dichotomous or ordinal data obtained at the item level. it has been proposed several solutions for studying dichotomous or ordinal data. christoffersson (1978) introduced a method for factor analyzing dichotomous data using tetra-choric correlations. muthén (1984) extended this method to provide a less computationally heavy approach. standard factor analysis implies two different levels of variables: unobserved factors, and observed indicators for those factors (items). the generalized least squares method to the factor analysis of dichotomous data requires one additional intermediate level between the observed data and the latent variable. thus two levels of abstraction are involved in the analysis: observed dichotomous or ordered categorical items are linked to unobserved latent response variables via tetra-choric or polychoric correlations. these unobserved latent response variables then serve as the indicators for the factors. in this model the factors summarize the relations among latent variables rather than directly among observed variables. another method for the factor analysis of dichotomous or ordered categorical items is that of maximum likelihood. as in the case of the generalized least squares method, the maximum likelihood approach use tetrachoric correlations among items, but approximates a numerical integration of a distribution of observations, assumed to be normal, using weighted sums. there exist also parallel analysis programs (buja, & eyuboglu, 1992; horn, 1965) that produce data sets based in aleatory numbers normally distributed, generated by the computer (o'connor, 2000). another manner of analysis
Contornos y confines del universo iconográfico precalchaquí del valle de Santa María
Scattolin,María Cristina;
Estudios atacame?os , 2006, DOI: 10.4067/S0718-10432006000200009
Abstract: this article offers a characterisation of pre-santamariana ceramics from santa maría valley, catamarca, argentina. more than 300 ceramic vessels from old collections are examined. during the first millennium ad, the attributes "dorsal-ventral symmetry", "effigy vessel", "oblique neck", and several others, were currently used and reflect a common trend, a habit, in shaping fine vessels. the analysis seeks to contribute and to adjust cultural chronological and symbolic legitimation models for the central area of northwest argentina. the results confirm that the material remains attributed to aguada style are barely represented in santa maría valley, and integrative effects originated from ambato or hualfín valley do not occur. on the contrary, the populations of santa maría valley consumed vessels whose making techniques and design ways were shared with the southern selvas occidentales, tafí valley, tapia-trancas basin, cajón valley, and southern calchaquí valley.
Sobre la completitud de los sistemas jurídicos
Redondo,María Cristina;
An??lisis filos?3fico , 2006,
Abstract: this paper analyses five different ways of understanding completeness as an ideal of legal systems. in doing so it essentially relies on the thesis discussed by carlos alchourrón regarding this subject. the paper stresses the need to distinguish (1) the criteria for the identification of the legally relevant texts, (2) the methods or rules that justify the passage from a content c to another content c1 and, (3) the criteria for the identification of valid norms belonging to the system. according to the dominant conception in legal theory, the rules of logic justify the passage from a content to another; such rules, however, are not accepted as membership criteria. this means that the notion of system that legal theorists use to organize the law is not the notion of a deductive system. in this conception the ideal of absolute completeness is a logically possible ideal. the conclusion reached in the article is that there are only two ways of understanding the ideal of "plenitude" or absolute completeness of a legal system: in a formalist view, through the introduction of residual rules of closure, or, in a moralistic view, by accepting critical morality as a criterium for legal validity.
Microscopic structure of the egg capsule of Atlantoraja cyclophora (Elasmobranchii: Rajidae: Arhynchobatinae)
Oddone, María Cristina;
Biota Neotropica , 2005, DOI: 10.1590/S1676-06032005000300020
Abstract: the microscopic structure of the egg capsules of atlantoraja cyclophora, a species endemic to the atlantic region of south america, is presented in this paper. in a transverse section, the dorsal face of the egg case is 70m in width, and is subdivided into four layers. ventrally, the egg capsule wall is 60 m wide and composed of three layers. both faces are covered by prickles which render the egg capsule surface striated to the naked eye.

Abstract: in a similar way to indigenous ethnocategories, categories used in archaeological classifications are an object of mental representations by researchers. hence, they can be scrutinized also, just as anthropology has studied native conceptual schemes. a methodical review of archaeological classifications would reduce subjective valuations that persist in scientific research. this idea is applied to the analysis of the first millennium a.d. in the santa maría valley, northwest argentina. the results show that archaeological categories are imposed by the uncontrolled incorporation of indigenous cognitive schemes and become emancipated from our control by routine repetition more than by scientific validation. this work confirms that "what is certain of the savage thought, is certain of all learned thought" and it ratifies the appropriateness of regularly subjecting archaeological categories to review
Las transformaciones en la identidad villera...: la conflictiva construcción de sentidos
Cravino,María Cristina;
Cuadernos de antropolog?-a social , 2002,
Abstract: the present issue aspires analyze the transformations of sense of the "villero" category in the 90's. in other words, how this sense and its contents were built starting from of the glances that the ways of communications, governmental actors and the proper "villeros" have. the point of departure is the narrow relationship between this new "villera" identity and the social process that happened since the structural crisis of the early of 80's and the governmental actions as the urban propositions to this sector, in the buenos aires city .
Los ancestros de calchaquí: una visión de la Colección Zavaleta
Scattolin,María Cristina;
Cuadernos de la Facultad de Humanidades y Ciencias Sociales. Universidad Nacional de Jujuy , 2003,
Abstract: in santa maría valley there exists an unbalance between the knowledge on societies prior to spanish conquest, those people to whom it was even attributed a name - "calchaquíes" - and the villages societies prior to them. it is proposed that the current archaeological knowledge of the societies of northwestern argentina has been affected by the collecting of archaeological objects by pot-hunters and other collectors between the end of xixth century and the beginnings of xxth's. some of their negative effects have been difficult to correct. one of them is the scarce knowledge of the material culture of the first millennium a. d. in this paper a series of objects of northern santa maría valley are considered: the collection that manuel zavaleta sold to the field museum of chicago. the analysis of a hundred of these pieces suggests that local populations at the valley had access to a stylistic universe partially shared with populations of eastern forests and calchaquí valley. such stylistic universe was used in their own manufactures and this fact has not been adequately investigated yet. though the results are yet preliminary, our objective is to offer elements about the representations distribution during the first millennium a.d., and to contribute to current discussion of symbolic legitimation in the territoryof santa maría valley and beyond.

Revista Pilquen , 2005,
Abstract: the present work places in the scholarship of initiation in research of the unco which project of research named "senses in the strategies of communication/education of the state and of ngos in works with teenagers in viedma" -2005/2006-. in the stage of this research that reflects this article, there were approached the speeches of the agents who were informing of the net adolescence viedma. there appear the theoretical limits that sustain the study and that imply a look from the field of the communication on the senses that there construct the adults who destine practices of 'promotion, prevention, expression' for teenagers. then some conclusions are outlined on how what we name a 'mercantile logic' and 'communicative logic' it expresses in the social policies destined for what is named "adolescence".

Cabral,María Cristina;
Revista Pilquen , 2009,
Abstract: the present work realizes a particular reading of certain transformations of the regime of accumulation in argentina in the decade of the 90 and your impact in the social policies, especially in those directed to attending to the teen population. it recaptures for this analysis the experience developed in viedma's city, the capital of the province of rio negro, during the years 2000-2006 from the implementation of the projects called proame -(programa de atención a menores en riesgo) program of attention to minors in risk-. these projects, directed to attending to the children and teenagers, were financed by the inter-american bank of development and implemented by state organisms and not governmental organizations. to cross in this analysis the experience of the projects proame helps to understand the economic - political dimension of a process in which there crystallize the way of national development and the limits of public policies expressed in the social policies. what leaves the implementation of the proame in the province of rio negro they are debates opened on the attention of the childhood and the adolescence, and the need to formulate and implement public inclusive policies, in the frame of manners of regulation of the economy with fort he attends on the part of the state.
