Adaptive integral assessment package for the A2UN@ project

This paper presents a first approach of Evaluation Engine Architecture (EEA) as proposal to support adaptive integral assessment, in the context of a virtual learning environment. The goal of our research is design an evaluation engine tool to assist in the whole assessment process within the A2UN@ project, linking that tool with the other key elements of a learning design (learning task, learning resources and learning support). The teachers would define the relation between knowledge, competencies, activities, resources and type of assessment. Providing this relation is possible obtain more accurate estimations of student's knowledge for adaptive evaluations and future recommendations. The process is supported by usage of educational standards and specifications and for an integral user modelling

La sabiduría como competencia gerencial

Aunque el concepto de sabiduría ha sido ampliamente estudiado por expertos de áreas como la filosofía, la religión y la psicología, aún enfrenta limitaciones en cuanto a su definición y evaluación. Por esto, el presente trabajo tiene como objetivo, formular una definición del concepto de sabiduría que permita realizar una propuesta de evaluación del concepto como competencia en los gerentes. Para esto, se realizó un análisis documental de tipo cualitativo. De esta manera, se analizaron diversos textos sobre la historia, las definiciones y las metodologías para evaluar tanto la sabiduría como las competencias; diferenciando la sabiduría de otros constructos y analizando la diferencia entre las competencias generales y las gerenciales para posteriormente, definir la sabiduría como una competencia gerencial. Como resultado de este análisis se generó un prototipo de prueba denominado SAPIENS-O, a través del cuál se busca evaluar la sabiduría como competencia gerencial. Como alcances del instrumento se pueden identificar la posibilidad de medir la sabiduría como competencia en los gerentes, la posibilidad de dar un nuevo panorama a las dificultades teóricas y empíricas sobre la sabiduría y la posibilidad de facilitar el estudio de la sabiduría en ambientes reales, más específicamente en ambientes organizacionales.

Role of the cultural values as a key part in the implementing of healthy practices : exploratory research

El concepto de organización saludable cada vez toma más fuerza en el ámbito empresarial y académico, a razón de su enfoque integral y al impacto generado en distintos grupos de interés. Debido a su reciente consolidación como concepto, existe un limitado cuerpo de investigación en torno al tema. Para contribuir a la generación de conocimiento en este sentido, se desarrolló un estudio exploratorio el cual tenía como objetivo identificar la relación existente entre la implementación de prácticas saludables en las organizaciones y los valores culturales. En el estudio participaron 66 sujetos a quienes se les administró un cuestionario compuesto por nueve variables, cinco provenientes del modelo de Hofstede (1980) y cuatro más que evaluaban la implementación de prácticas organizacionales saludables. Los resultados obtenidos muestran que los valores culturales predicen la implementación de prácticas saludables.

The project of land restitution in Colombia: an illustration of the civilizing force of hypocrisy?

This article offers a theoretical interpretation of the dispositions on land restitution contained in the famous “Victims’ Bill”, which was debated in the Colombian Congress during the year 2008. The bill included specific mechanisms aimed at guaranteeing the restitution of land to victims of the Colombian armed conflict. At the time, the bill was endorsed by all the main political actors in the country –notably the government and the elites that support it, on the one hand, and victims’ and human rights organizations and other opposition groups, on the other–. The fact that the restitution of land to victims of the Colombian armed conflict was being considered as a serious possibility by all political actors in the country seemed to indicate the existence of a consensus among actors whose positions are ordinarily opposed, on an issue that has traditionally led to high levels of polarization. This consensus is quite puzzling, because it seems to be at odds with the interests and/or the conceptions of justice advocated by these political actors, and because the restitution of land faces enormous difficulties both from a factual and a normative point of view, which indicates that it may not necessarily be the best alternative for dealing with the issue of land distribution in Colombia. This article offers an interpretation of said consensus, arguing that it is only an apparent consensus in which the actors are actually misrepresenting their interests and conceptions of justice, while at the same time adopting divergent strategies of implementation aimed at fulfilling their true interests. Nevertheless, the article concludes that the common adherence by all actors to the principle of restorative justice might bring about its actual realization, and thus produce an outcome that, in spite (and perhaps even because) of being unintended, might substantively contribute to solving the problem of unequal land distribution in Colombia. Even though the article focuses in some detail on the specificities of the 2008 Bill, it attempts to make a general argument about the state of the discussion on how to deal with the issue of land distribution in the country. Consequently, it may still be relevant today, especially considering that a new Bill on land restitution is currently being discussed in Congress, which includes the same restitution goals as the Victims’ Bill and many of its procedural and substantive details, and which therefore seems to reflect a similar consensus to the one analyzed in the article.

The innate concepts in Chomsky’s work: definition and proposal of an empirical method for their study

This article focuses on innate concepts: their definition, according to the linguistic work of Noam Chomsky, and the outline of a method for their study. As an introduction to the subject some academic conceptions of the concept acquisition are pointed out, and it is claimed that there is a lack of an empirical method for the study of innate concepts. Next, the article presents the definition that Chomsky has defended over time about such concepts. Finally, in a theoretical way, it presents the conditions for an empirical procedure for the study of innate concepts, called semantic analysis of corpus

Psychometric properties of the scale NBAS applied to preterm or low birth weight

Objective: to assess, in a randomized sample of measurements made with the NBAS scale, in preterm and / or low birth weight babies, some psychometric characteristics of the same as her construct validity and internal consistency. Materials and methods: we designed a study of assessment of Psychometric properties. From a study of cross-sectional measurements, there were made assessment of the statistic behavior of the items, individually and in their internal consistency, then, there were carried out, type exploratory and confirmatory factor analysis. Results: we find that, in the analysis of preterm or low birth weight babies, the scale remains largely, the overall structure of factors proposed since 1982, in relation to the dimensions of habituation, social interactive and complementary. The items that make up the dimensions of SNA and motor systems are integrated. Also, we found Cronbach alpha values for internal consistency, which reflects higher to medium correlation levels in the behavioral and reflex items. Conclusion: the NBAS scale reflects characteristics of construct validity and internal consistency, which credits it as a useful tool in clinical assessment of neurodevelopmental effects of preterm or low birth weight babies. It is necessary to analyze the structure of the scale when used for purposes of scientific research.

The High Education Teacher, an Agent of Moral Development

The article shows the classroom like an workplace to move moral development, from the relationship between students and professors in the university atmosphere. It proposes elements to take to the practice the ethics education a transverse curriculum line. It assumes the ethics, from a plural perspective, founded on the knowledge and the human action. It joins the integral formation with the conceptions of education, curriculum, pedagogical models and methodologies of education. It proposes actions to demonstrate the commitment of the professor with the integral formation. Finally, concludes that the professor is agent of moral development and that in the classroom is constructed: identity, autonomy and responsibility, from open and plural relation between professors and students and between these and the knowledge.

La experiencia de los receptores en el trasplante de órganos y tejidos

El trasplante de órganos y/o tejidos es considerado como una opción terapéutica viable para el tratamiento tanto de enfermedades crónicas o en estadios terminales, como de afectaciones no vitales, pero que generen una disminución en la calidad de vida percibida por el paciente. Este procedimiento, de carácter multidimensional, está compuesto por 3 actores principales: el donante, el órgano/tejido, y el receptor. Si bien un porcentaje significativo de investigaciones y planes de intervención han girado en torno a la dimensión biológica del trasplante, y a la promoción de la donación; el interés por la experiencia psicosocial y la calidad de vida de los receptores en este proceso ha aumentado durante la última década. En relación con esto, la presente monografía se plantea como objetivo general la exploración de la experiencia y los significados construidos por los pacientes trasplantados, a través de una revisión sistemática de la literatura sobre esta temática. Para ello, se plantearon unos objetivos específicos derivados del general, se seleccionaron términos o palabras claves por cada uno de estos, y se realizó una búsqueda en 5 bases de datos para revistas indexadas: Ebsco Host (Academic Search; y Psychology and Behavioral Sciences Collection); Proquest; Pubmed; y Science Direct. A partir de los resultados, se establece que si bien la vivencia de los receptores ha comenzado a ser investigada, aún es necesaria una mayor exploración sobre la experiencia de estos pacientes; exploración que carecería de objetivo si no se hiciera a través de las narrativas o testimonios de los mismos receptores

Importância da relação Escola/Família no processo de inclusão de crianças com paralisa cerebral em creche

Este estudo enquadra-se numa avaliação da importância da relação escola/família no processo de inclusão de crianças com Paralisia Cerebral em contexto de Creche. Além dos profissionais especializados contribuírem para o desenvolvimento de crianças com Paralisia Cerebral, a família assume um papel fulcral. A intervenção da família é assim essencial no processo de desenvolvimento/inclusão destas crianças ao longo da vida. Nesse sentido, destacamos como objetivos primordiais: identificar o envolvimento da família e as dinâmicas relacionais com vista ao desenvolvimento pessoal e social da criança, aferir as relações interpessoais dos técnicos e professores que lidam com a inclusão de crianças com PC, perceber a perspetiva que os terapeutas têm acerca da inclusão de crianças com PC, conhecer as conceções dos educadores/professores sobre inclusão, saber como a PC é integrada em Creche, identificar a ação dos pais e da escola na inclusão de uma criança com PC e identificar a articulação do educador/professor com os pais e vice-versa. Para a realização deste estudo, optou-se por utilizar uma metodologia de natureza qualitativa – estudo de caso. Realizaram-se entrevistas semiestruturadas aos intervenientes no processo de desenvolvimento da criança (pais, educadores/professores, terapeutas) para recolher dados. A informação obtida foi apurada mediante análise de conteúdo dessas mesmas entrevistas.

Student projects: plagiarism and assessment

Within the Information Technology degree programme of the University of Reading, the students undertake a major project in their final year. The module is both a hurdle to an honours degree and significant in terms of assessment weighting. The two year history so far has shown that bad citation and plagiarism are issues, and in one case called for the due referral of a project report. In the light of experience to date, we are focusing firstly on plagiarism prevention, giving generic advice on report writing and citation practice, and secondly on detection. In the longer term, I believe we need to reflect on what capabilities we should be creating in our undergraduates and therefore what and how we should be assessing them.

Agonist-dependent internalization of D2 receptors: imaging quantification by confocal microscopy

In positron emission tomography and single photon emission computed tomography studies using D2 dopamine (DA) receptor radiotracers, a decrease in radiotracer binding potential (BP) is usually interpreted in terms of increased competition with synaptic DA. However, some data suggest that this signal may also reflect agonist (DA)-induced increases in D2 receptor (D2R) internalization, a process which would presumably also decrease the population of receptors available for binding to hydrophilic radioligands. To advance interpretation of alterations in D2 radiotracer BP, direct methods of assessment of D2R internalization are required. Here, we describe a confocal microscopy-based approach for the quantification of agonist-dependent receptor internalization. The method relies upon double-labeling of the receptors with antibodies directed against intracellular as well as extracellular epitopes. Following agonist stimulation, DA D2R internalization was quantified by differentiating, in optical cell sections, the signal due to the staining of the extracellular from intracellular epitopes of D2Rs. Receptor internalization was increased in the presence of the D2 agonists DA and bromocriptine, but not the D1 agonist SKF38393. Pretreatment with either the D2 antagonist sulpiride, or inhibitors of internalization (phenylarsine oxide and high molarity sucrose), blocked D2-agonist induced receptor internalization, thus validating this method in vitro. This approach therefore provides a direct and streamlined methodology for investigating the pharmacological and mechanistic aspects of D2R internalization, and should inform the interpretation of results from in vivo receptor imaging studies.

A decade of research and development in disability, virtual reality and associated technologies: review of ICDVRAT 1996−2006

The International Conference (series) on Disability, Virtual Reality and Associated Technologies (ICDVRAT) this year held its sixth biennial conference, celebrating ten years of research and development in this field. A total of 220 papers have been presented at the first six conferences, addressing potential, development, exploration and examination of how these technologies can be applied in disabilities research and practice. The research community is broad and multi-disciplined, comprising a variety of scientific and medical researchers, rehabilitation therapists, educators and practitioners. Likewise, technologies, their applications and target user populations are also broad, ranging from sensors positioned on real world objects to fully immersive interactive simulated environments. A common factor is the desire to identify what the technologies have to offer and how they can provide added value to existing methods of assessment, rehabilitation and support for individuals with disabilities. This paper presents a brief review of the first decade of research and development in the ICDVRAT community, defining technologies, applications and target user populations served.

The decomposition of some RDX and HMX based materials in the one dimensional time to explosion apparatus. Part 2. Estimating the violence of the cook-off event

Various methods of assessment have been applied to the One Dimensional Time to Explosion (ODTX) apparatus and experiments with the aim of allowing an estimate of the comparative violence of the explosion event to be made. Non-mechanical methods used were a simple visual inspection, measuring the increase in the void volume of the anvils following an explosion and measuring the velocity of the sound produced by the explosion over 1 metre. Mechanical methods used included monitoring piezo-electric devices inserted in the frame of the machine and measuring the rotational velocity of a rotating bar placed on the top of the anvils after it had been displaced by the shock wave. This last method, which resembles original Hopkinson Bar experiments, seemed the easiest to apply and analyse, giving relative rankings of violence and the possibility of the calculation of a “detonation” pressure.
