D=10 dyonic black holes in string inspired models

We consider string-inspired models in D=10 spacetime dimensions, which include couplings with 1- and 3-form fields as well as R4 higher-curvature corrections to the gravitational action. For such models, we explicitly construct a family of black hole solutions with both electric and magnetic charges, and with different horizon topologies. The solutions exhibit some features similar to those of self-gravitating monopoles in Einstein-Yang-Mills theory, which we discuss. When higher-curvature corrections are switched off, our solutions reduce to charged p-brane solutions previously studied in the literature. Novel qualitative features appear due to the R4 terms, though. Such is the case for the emergence of branch singularities for charged solutions that, nonetheless, can be shielded by the event horizon.Fil: Giribet, Gaston Enrique.

Q curvature and gravity

In this paper, we consider a family of n-dimensional, higher-curvature theories of gravity whose action is given by a series of dimensionally extended conformal invariants. The latter correspond to higher-order generalizations of the Branson Q curvature, which is an important notion of conformal geometry that has been recently considered in physics in different contexts. The family of theories we study here includes special cases of conformal invariant theories in even dimensions. We study different aspects of these theories and their relation to other higher-curvature theories present in the literature.Fil: Chernicoff, Mariano.

Regulación de la comunicación oportuna de circunstancias, como requisito para solicitar la prolongación de la prisión preventiva

La presente exploración científica versa respecto la cuestionable regulación contenida en el artículo 274 del Código Adjetivo Penal que permite la posibilidad que una vez declarada la prisión preventiva; el Ministerio Público no ejecute las diligencias necesarias para la investigación, o bien no sean las suficientes para lograr la finalidad de ésta, dejando transcurrir el tiempo de duración de la medida cautelar procesal de índole personal y justamente al estar ad portas de su finalización, recién el titular del ejercicio de la acción penal, requiera la prolongación de la medida de coerción procesal, atentando contra diversos principios como del plazo razonable, la excepcionalidad y la subsidiaridad, teniendo en dicha situación un argumento para fundar o justificar la inacción indagatoria, perjudicando al imputado, convirtiendo en desproporcional su condición situación jurídica; advirtiendo por ello, la necesidad de regular que la comunicación de las circunstancias que sustentaría la prolongación de la prisión preventiva deba ser comunicada en la primera oportunidad que se presenten, como requisito de la prolongación y no esperar al vencimiento de la referida prisión; para ello se considera enunciar la siguiente pregunta: ¿Qué fundamentos jurídicos sustentará la regulación de la comunicación oportuna de circunstancias, como requisito para solicitar la prolongación de la prisión preventiva? La ejecución de la presente investigación, se sustenta en el empleo de distintos procedimientos generales para recabar y contrastar distinta información especializada, así se empleó métodos como el Método Científico, Método Inductivo, Método Deductivo, Método Analítico, Método Histórico, Método Doctrinario; de igual modo se recurrió a procedimientos específicos para recabar información como a las Técnicas: Observación, Análisis de Documentos y Entrevistas a especialistas en el tema objeto de estudio; con sus respectivos instrumentos de investigación, específicamente nos apoyamos en la Guía de Observación, las Fichas bibliográficas y el Cuestionario de Entrevistas. 7 Luego de empelar los métodos, técnicas e instrumentos, se logró obtener resultados, los mismos que fueron discutidos en relación con los objetivos planteados, los mismos que dan soporte a la posición planteada por el investigador llegando a concluir que los fundamentos jurídicos para regular la comunicación oportuna de circunstancias, como requisito para solicitar la prolongación de la prisión preventiva son: El respeto constitucional a la Dignidad de la Persona Humana, el derecho a la razonabilidad del plazo de la prisión preventiva y el derecho a la libertad personal. Finalizada la exploración científica se considera postular conclusiones, así como una recomendación que concretiza los resultados y permite ofrecer una propuesta legislativa como aporte del estudio básicoThe regulation of Euthanasia is the object of study, specifically the determination of its constitutional arguments as a clear manifestation of decision-making on ethical, transparent arguments and respectfor the autonomy of will of patientswith terminal illnesses, in order to Ontar with a clear legal framework and precise regulations that establish the necessary procedures and safeguards to prevent abuses and protect the interests of the terminally ill patient. The research is based on doctrinal arguments, as well as in the light of the emblematic case of Ana Estarda, also finding support in the positions of the specialists in the study, considering as a problem statement: What constitutional foundations will sustain the recognition of euthanasia as a fundamental right in Peru? Once the execution of the study began and ended, using a methodology according to the type of research, the hypothesis formulated in the sense that: the constitutional foundations to recognize euthanasia as a fundamental right in Peru are: Respect and constitutional defense of the Dignity of the Human Person; the right to die with dignity and not to be subjected to cruel and inhuman treatment. The above is based on results, widely discussed, warning that what the researcher warned is a latent problem, existing in the legal and social field, necessary for immediate regulation, consistent in the light of the emblematic case of Ana Estrada. Once the study is completed, it is considered to present results for the objectives set, the same ones that are conducted in the conclusions and in the recommendation related to the proposal of legal regulation whose text is also included in this report, as a clear expression of respect and constitutional defense of the Dignity of the Human Person; the right to die with dignity and not to be subjected to cruel and inhuman This scientific exploration deals with the questionable regulation contained in article 274 of the Criminal Code, which allows the possibility that once pretrial detention has beendeclared; the Public Prosecutor's Office does not carry out the necessary steps for the investigation, or they are not sufficient to achieve the purpose of the investigation, allowing the duration of the procedural precautionary measure of a personal nature to elapse and precisely when the holder of the exercise of the criminal action is on the verge of its completion, requires the prolongation of the measure of procedural coercion, violating various principles such as reasonable time, exceptionality and subsidiarity, having in that situation an argument to found or justify the inaction of inquiry, harmingthe accused, making his status disproportionate Noting therefore the need to regulate that the communication of the circumstances that would support the extension of the preventive detention must be communicated at the first opportunity that arises, as a requirement of the extension and not wait for the expiration of the aforementioned prison; for this purpose, it is considered to state the following question: What legal grounds will support the regulation of the timely communication of circumstances, as a requirement to request the extension of pretrial detention? Theexecution of this research, is based on the use of different general procedures to collect and contrast different specialized information, thus methods such as the Scientific Method, Inductive Method, Deductive Method, Analytical Method, Historical Method, Doctrinal Method; in the same way specific procedures were used to collect information such as the Techniques: Observation, Analysis of Documents and Interviews with specialists in the subject under study; with their respective research instruments, we specifically rely on the Observation Guide, the Bibliographic Records and the Interview Questionnaire. After employing the methods, techniques and instruments, it was possible to obtain results, which were discussed in relation to the objectives proposed, the same that support the position raised by the investigator, concluding that the legal bases to 9 regulate the timely communication of circumstances, as a requirement to request the extension of pretrial detention are: Constitutional respect for the dignity of the human person, the right to reasonableness of the term of pretrial detention and the right to personal liberty.

Horizon symmetries and hairy black holes in AdS

We investigate whether supertranslation symmetry may appear in a scenario that involves black holes in AdS space. The framework we consider is massive 3D gravity, which admits a rich black hole phase space, including stationary AdS black holes with softly decaying hair. We consider a set of asymptotic conditions that permits such decaying near the boundary, and which, in addition to the local conformal symmetry, is preserved by an extra local current. The corresponding algebra of diffeomorphisms consists of two copies of Virasoro algebra in semi-direct sum with an infinite-dimensional Abelian ideal. We then reorient the analysis to the near horizon region, where infinite-dimensional symmetries also appear. The supertranslation symmetry at the horizon yields an infinite set of non-trivial charges, which we explicitly compute. The zero-mode of these charges correctly reproduces the black hole entropy. In contrast to Einstein gravity, in the higher-derivative theory subleading terms in the near horizon expansion contribute to the near horizon charges. Such terms happen to capture the higher-curvature corrections to the Bekenstein area law.Fil: Donnay, Laura. Vienna University of Technology; AustriaFil: Giribet, Gaston Enrique.

Parenting styles and adolescent adjustment

En este artículo se presentan los resultados de un estudio realizado sobre una muestra de 848 adolescentes de edades comprendidas entre los 12 y los 17 años, que cumplimentaron un cuestionario que incluía una escala con 6 dimensiones sobre su percepción del estilo parental o relacional materno y paterno y otros instrumentos para evaluar el ajuste adolescente. La realización de un análisis de conglomerados a partir de las puntuaciones en las 6 dimensiones que componían la escala reveló la existencia de tres grupos de padres y de madres que fueron definidos como democráticos, estrictos e indiferentes. El trabajo ofrece un modelo de categorización de las relaciones entre padres e hijos que posee un carácter bidireccional y que incluye dimensiones como la revelación, el humor y la promoción de autonomía, que enriquecen la perspectiva clásica basada exclusivamente en las dimensiones de afecto y disciplina. El estilo materno y el paterno fueron evaluados por separado encontrándose una alta coincidencia entre ambos estilos, que además mostraron una relación muy significativa con el ajuste de chicos y chicas.The paper presents the results of a study with a sample of 848 adolescents between 12 and 17 years who completed a questionnaire that included a 6 dimensions scale about their perception of maternal and paternal educational style and other measures of adolescent adjustment. The results of cluster analysis showed 3 groups of mothers and fathers that were defined as: authoritative, strict, and indifferent. The study has permitted us to create a bi-directional model which categorises the relationships between parents and adolescents and which includes factors such as self-disclosure, sense of humour and the encouragement of adolescent independence. These factors enrich the traditional perspective based solely on affection and discipline. The parenting style of mothers and fathers, evaluated separately, showed a high coincidence and furthermore showed a significant relationship with adolescent well-being.Ministerio de Ciencia y Tecnología BSO2002-0302

Juventud Rural: Factores que influyen en el desarrollo de la actividad agropecuaria. Reflexiones sobre el caso argentino

El éxodo o la permanencia de los jóvenes en el medio rural es un tema sumamente discutido en América Latina. Este trabajo pretende contribuir a esta discusión sobre la base de una investigación empírica realizada a 400 jóvenes en Argentina, en la cual se muestran cómo influyen diferentes variables en el mantenimiento de los jóvenes en el medio rural realizando actividades agropecuarias. La hipótesis que se plantea y que finalmente se valida es que la pertenencia a familias productoras agropecuarias y la continuidad de estudios vinculados a la actividad agropecuaria son los factores claves que permiten mantener a los jóvenes en el medio rural realizando actividades agropecuarias. Las técnicas estadísticas utilizadas para realizar el análisis descriptivo son tablas de contingencia y comparación de medias, en tanto la regresión logística binaria múltiple se utiliza para realizar el análisis de dependencia y validar la hipótesis planteada.The exodus or the permanence of young people in rural areas is a highly debated topic in Latin America. This work aims to contribute to this discussion based on an empirical research with a survey of 400 young people in Argentina. This study shows how different variables influence in keeping young people in rural areas engaging in agriculture activities. The hypothesis that arises and that is finally validated is that belonging to farming families and studies related to agricultural activity are the key factors that allow young people to settle in rural areas and engage in agriculture. The statistical techniques used for descriptive analysis are contingency tables and comparison of means, while the multiple binary logistic regressions are used to perform dependency analysis and validate the hypothesis.Fil: Sili, Marcelo Enrique.

Quasinormal modes and black hole hairs in AdS

Holography relates the quasinormal mode frequencies of AdS black holes to the pole structure of the dual field theory propagator. These modes thus provide the timescale for the approach to thermal equilibrium in the CFT. Here, we study how such pole structure and, in particular, the time to equilibrium can get modified in the presence of a black hole hair. More precisely, we consider in AdS a set of relaxed boundary conditions that allow for a low decaying graviton mode near the boundary, which triggers an additional degree of freedom. We solve the scalar field response on such background analytically and nonperturbatively in the hair parameter, and we obtain how the pole structure gets affected by the presence of a black hole hair, relative to that of the usual AdS black hole geometry. The setup we consider is a massive 3D gravity theory, which admits a one-parameter family deformation of Banados-Teitelboim-Zanelli (BTZ) solution and enables us to solve the problem analytically. The theory also admits an AdS 3 soliton which gives a family of vacua that can be constructed from the hairy black hole by means of a double Wick rotation. The spectrum of normal modes on the latter geometry can also be solved analytically; we study its properties in relation to those of the AdS 3 vacuum.Fil: Chernicoff, Mariano.
