El trabajo por rincones en educación infantil

Treball final de Grau en Mestre o Mestra d'Educació Infantil. Codi: MI1040. Curs acadèmic 2014-2015El presente TFG, de revisión teórica, recopila y analiza información publicada referente a la organización de los espacios en Educación Infantil. El objetivo principal es estudiar en profundidad el trabajo por rincones en las aulas de Educación Infantil y el aprendizaje que los niños y niñas adquieren con esta metodología. Para ello se lleva a cabo una revisión bibliográfica en la que se detalla que el trabajo por rincones es una de las alternativas actuales de organización del aula de infantil y que mediante este método, la organización del espacio del aula se realiza por zonas que están destinadas a diferentes usos, en cada zona se ofrecen diferentes propuestas para llevar a cabo actividades pertenecientes a distintos ámbitos educativos en las que los niños y niñas son el eje central del proceso educativo y son los constructores de su propio aprendizaje. Asimismo, se estudia los tipos de rincones que podemos encontrar, el origen, en qué consisten, la relación entre éstos y las competencias, la variedad de ellos que se pueden organizar en un aula, las ventajas de este tipo de trabajo, los destinatarios y el papel del alumnado y del profesorado en esta metodología pretendiendo reunir así la realidad de las aulas de Educación Infantil que trabajan de acuerdo a este método

Perspectiva seniana de la desigualdad económica como motivo de cuestionamiento de la organización social

Entre los temas de análisis crítico se encuentra la naturaleza disciplinar de la economía. Están quienes argumentan que por fundamentarse matemáticamente debe constituirse como una ciencia teórica. Esta postura, amparada en el concepto de neutralidad valorativa, no considera propio de la ciencia económica la inclusión de valores. Otras corrientes sostienen planteos claramente normativos, es decir, una vinculación con la ética. Algunos, como Amartya Sen, la relacionan estrechamente con la política, no sólo como ciencia sino como un accionar que debe tender a modificar las relaciones económicas y sociales. Sen se replantea las libertades fundamentales como elementos indispensables para llevara una mejor calidad de vida. Los dilemas socioeconómicos, tales como la pobreza extrema, requieren de un análisis ¡interdisciplinario, especialmente cuando esto lleva a cuestionar la legitimación social del régimen democrático. El trabajo como elemento autodignificante debe tender a mejorar la cohesión social, por medio de una distribución que propenda al bienestar de todos los miembros de la sociedad. Este trabajo vinculará las teorías senianas de las capacidades y funcionamientos, con sus estudios acerca de la pobreza, la forma de medirla, la desigualdad económica, y cómo intervenir para mejorar la equidad en la distribución social.Fil: Frutos Torres, Silvia.

NiMo syntax: part 1

Many formalisms for the specification for concurrent and distributed systems have emerged. In particular considering boxes and strings approaches. Examples are action calculi, rewriting logic and graph rewriting, bigraphs. The boxes and string metaphor is addressed with different levels of granularity. One of the approaches is to consider a process network as an hypergraph. Based in this general framework, we encode NiMo nets as a class of Annotated hypergraphs. This class is defined by giving the alphabet and the operations used to construct such programs. Therefore we treat only editing operations on labelled hypergraphs and afterwards how this editing operation affects the graph. Graph transformation (execution rules) is not covered here.Postprint (published version

Dynamic and multi-pharmacophore modeling for designing polo-box domain inhibitors.

The polo-like kinase 1 (Plk1) is a critical regulator of cell division that is overexpressed in many types of tumors. Thus, a strategy in the treatment of cancer has been to target the kinase activity (ATPase domain) or substrate-binding domain (Polo-box Domain, PBD) of Plk1. However, only few synthetic small molecules have been identified that target the Plk1-PBD. Here, we have applied an integrative approach that combines pharmacophore modeling, molecular docking, virtual screening, and in vitro testing to discover novel Plk1-PBD inhibitors. Nine Plk1-PBD crystal structures were used to generate structure-based hypotheses. A common pharmacophore model (Hypo1) composed of five chemical features was selected from the 9 structure-based hypotheses and used for virtual screening of a drug-like database consisting of 159,757 compounds to identify novel Plk1-PBD inhibitors. The virtual screening technique revealed 9,327 compounds with a maximum fit value of 3 or greater, which were selected and subjected to molecular docking analyses. This approach yielded 93 compounds that made good interactions with critical residues within the Plk1-PBD active site. The testing of these 93 compounds in vitro for their ability to inhibit the Plk1-PBD, showed that many of these compounds had Plk1-PBD inhibitory activity and that compound Chemistry_28272 was the most potent Plk1-PBD inhibitor. Thus Chemistry_28272 and the other top compounds are novel Plk1-PBD inhibitors and could be used for the development of cancer therapeutics

A Typed Model for Dynamic Authorizations

Security requirements in distributed software systems are inherently dynamic. In the case of authorization policies, resources are meant to be accessed only by authorized parties, but the authorization to access a resource may be dynamically granted/yielded. We describe ongoing work on a model for specifying communication and dynamic authorization handling. We build upon the pi-calculus so as to enrich communication-based systems with authorization specification and delegation; here authorizations regard channel usage and delegation refers to the act of yielding an authorization to another party. Our model includes: (i) a novel scoping construct for authorization, which allows to specify authorization boundaries, and (ii) communication primitives for authorizations, which allow to pass around authorizations to act on a given channel. An authorization error may consist in, e.g., performing an action along a name which is not under an appropriate authorization scope. We introduce a typing discipline that ensures that processes never reduce to authorization errors, even when authorizations are dynamically delegated.Comment: In Proceedings PLACES 2015, arXiv:1602.0325

Dynamic Role Authorization in Multiparty Conversations

Protocol specifications often identify the roles involved in communications. In multiparty protocols that involve task delegation it is often useful to consider settings in which different sites may act on behalf of a single role. It is then crucial to control the roles that the different parties are authorized to represent, including the case in which role authorizations are determined only at runtime. Building on previous work on conversation types with flexible role assignment, here we report initial results on a typed framework for the analysis of multiparty communications with dynamic role authorization and delegation. In the underlying process model, communication prefixes are annotated with role authorizations and authorizations can be passed around. We extend the conversation type system so as to statically distinguish processes that never incur in authorization errors. The proposed static discipline guarantees that processes are always authorized to communicate on behalf of an intended role, also covering the case in which authorizations are dynamically passed around in messages.Comment: In Proceedings BEAT 2014, arXiv:1408.556

Community Gardening & Nutrition Education Event to Improve Healthy Living

Catholic Charities (CC) is a non-governmental organization that is a part of a network of charities that focuses on immediate disaster response and helps to stabilize impacted communities. Their humanitarian-aid includes housing assistance, funding for health care services, disaster relief and distribution of food. The macro-level problem is too many people in Monterey County are at risk of diabetes. The micro-level problem is that residents of Eden Housing have a higher risk of not eating healthy foods. This project serves Eden Housing residents in Seaside where a gardening and nutrition education event was held to assist residents to plant vegetables and learn about nutritious eating and drinking. The expected outcome of the project is for Eden housing residents to learn about healthier eating and drinking options. The project was successful because families came together and planted vegetables every week. The agency will continue to lead gardening events to address obesity levels in Monterey County
