Variants of temporal defeasible logics for modelling norm modifications

This paper proposes some variants of Temporal Defeasible Logic (TDL) to reason about normative modifications. These variants make it possible to differentiate cases in which, for example, modifications at some time change legal rules but their conclusions persist afterwards from cases where also their conclusions are blocked.

The norm of the K- Th derivative of the X-symmetric power of an operator

In this paper, the exact value for the norm of directional derivatives, of all orders, for symmetric tensor powers of operators on finite dimensional vector spaces is presented. Using this result, an upper bound for the norm of all directional derivatives of immanants is obtained.

Modelo de Gestion Intersectorial para la formalización de villas, a partir de la revisión de normativa urbana, marco jurídico-político, y la innovación tecnológica de los recursos. Intersectorial management model for the formality of the illegal growth settles beginning from the revision of the urban norm, political - juridical, and the technological innovation of the resources.

El Proyecto que se presenta en esta convocatoria está relacionado con el diseño y desarrollo de procesos de gestión intersectorial para la reconversión formal del hábitat en asentamientos de crecimiento espontáneo e ilegal a partir de la la revisión de marcos legales y normativos respecto del derecho al uso de suelo urbano y la seguridad jurídica en la tenencia (regulación dominial) bajo un enfoque sustentable de los Derechos Humanos (DDHH) como así también a partir de la innovación tecnológica de los recursos para el mejoramiento habitacional en el marco de los aportes relacionados con la Responsabilidad Social Empresarial (RSE) .La originalidad, en este caso, se basa en la exploración de nuevos procesos de gestión mixta en los que intervienen diversos actores: ESTADO, SOCIEDAD, EMPRESA y COMUNIDAD CIENTIFICA, configurando un circuito intersectorial de gestión, capacitación y producción de hábitat que respondan al fortalecimiento del desarrollo comunitario, entendido como desarrollo económico con inclusión social y urbana.Los objetivos están relacionados con el fortalecimiento de la producción integral del hábitat social procurando el desarrollo genuino de las comunidades a partir de la expansión de sus capacidades y sus derechos.El presente proyecto de investigación explorará la producción de hábitat y de ciudad informal procurando reconvertirla hacia un modelo de gestión sustentable (normativo y tecnológico), basado en la necesidad de producir ciudadanía digna a partir de la construcción formal de hábitat.La propuesta del proyecto supone la participación intersectorial en la planificación formal y en la toma de decisiones para una inclusión social y económica, en el marco de un modelo de desarrollo de génesis inclusor, constituyéndose en un avance de conocimientos del propio campo disciplinar (hábitat) como así también de otros campos afines a los mismos (jurídico- social - económico- productivo- político ).

Negative Correlation Between of Light Ions Content and Radon Concentration: Particularity of Tbilisi City Air Pollution, or Norm for the Urbanized Locality?

In Tbilisi according to the data of the complex monitoring of light ions concentration, radon and sub-micron aerosols the effect of feedback of intensity of ionizing radiation with the light ions content in atmosphere is discovered.

Norm inequalities in multidimensional Lorentz spaces

In this paper we obtain necessary and sufficient conditions for double trigonometric series to belong to generalized Lorentz spaces, not symmetric in general. Estimates for the norms are given in terms of coefficients.

Norm convolution inequalities in Lebesgue spaces

We obtain upper and lower estimates of the (p; q) norm of the con-volution operator. The upper estimate sharpens the Young-type inequalities due to O'Neil and Stepanov.

Determinants of the educational use of digital learning materials: The mediating role of self-efficacy, perceived norm and attitude

Initiatives to stimulate the development and propagation of open educational resources (OER) need a sufficiently large community that can be mobilized to participate in this endeavour. Failure to achieve this could lead to underuse of OER. In the context of the Wikiwijs initiative a large scale survey was undertaken amongst primary and secondary school teachers to explore possible determinants of the educational use of digital learning materials (DLMs). Basing on the Integrative Model of Behaviour Prediction it was conjectured that self-efficacy, attitude and perceived norm would take a central role in explaining the intention to use DLMs. Several other predictors were added to the model as well whose effects were hypothesized to be mediated by the three central variables.All conjectured relationships were found using path analysis on survey data from 1484 teachers. Intention to DLMs was most strongly determined by self-efficacy, followed by attitude. ICT proficiency was in its turn the strongest predictor of self-efficacy. Perceived norm played only a limited role in the intention to use DLMs. Concluding, it seems paramount for the success of projects such as Wikiwijs to train teachers in the use of digital learning materials and ICT (e.g. the digital blackboard) and to impact on their attitude.
