Efetividade dos direitos trabalhistas e os princípios constitucionais concretizadores da proteção laboral

The Brazilian Constitution aims to regularize the broadest possible the fundamental grounded in the value and supreme principle of human dignity, supporting a Democratic State of Law, to essentially give basic rights to all for a dignified existence. As the result of a historical development, fundamental rights incorporated by legal order represents a real reaction against acts that ignored the dignity of each person in one of these scenarios, especially inserted into the labor relationship, the principle of protection comes to balance and compose such relationship between employers and workers, raising this principle as axiological essence of this subject, based especially on the protection and guarantee of fundamental rights of the worker. For this study, was developed a literature research using books, legislation, legal websites and articles related to the subject, in order to analyze the principle of protection insert in the legal order, properly authoritative on the principle of equality, the social value of the work of human dignity to confer protection to the most vulnerable and admittedly weak of the labor relationship in order to serve the specific regulations legal practical tools and effective protection, against the employer hierarchical power and steering that can not change into abuses and attacks on the fundamental rights of the worker. In conclusion, is not enough, recognizing the vulnerability of the worker, it is necessary to carry out protective legal instruments in line with the the human dignity, consectário logical fundamental rights of workers, to be held in a proportional manner and sometimes flexible, depending on the case. Protection has a beginning and end to ensure that the human dignity that must presuppose a working relationship achieved by orderly and normative power of constitutional norms, with the aim of designing that labor is not an end in itself, but a means to the achievement of the economic advancement by promoting social development and providing necessary support for the increasingly marked impairment of fundamental rights of the worker

Tear identitário:a prática docente em arte como conhecimento compartilhado

This investigative tissue is about the formation of identification processes of teachers and pedagogical practice of Art, in Teresina city. This search comprised the sum of the needs presented, agreed upon with the teachers engaged in the process, it was developed through the establishment of interactive environment Loom Team where collaboration and critical reflection were steering actions to promote the understanding of existing connections or relations within the processes of identifications and the pedagogical practice of Art. The tissue is formed by the polyphonic plot of the critical reflection of nine teachers of Art who engaged voluntarily and this investigation of formative nature and a production of knowledge. All these teachers have degree and the course of artistic education and especial qualification in Fine Arts and/or Drawing. The texture, which we denominated Identification Loom: The pedagogical practice of Art as share knowledge is (de) (re) construction of knowledge resulting from the critical reflection, in an environment of collaboration, which may have implications and ethical political attitudes in the pedagogical practice of the group. Within this context, we pose the following question: - How does the pedagogical practice in Art influence and/or be influenced by the identification processes of the teachers, and how do they interfere with the search and manifestation of the knowledge involved and the investment in professionalization? In view of this query, we make use of the cooperative investigation, having social history as theoretical reference and as analytic perspective of interactive and dialogical-reflexive processes. Thus, social historic theory, cooperative approach and pedagogical practice were the major components of the plot. The methodological texture counted on the threads of dialogical reflexion, of mediation and of collaboration. The conceptual formulation, the recording in videos of classes and the narratives of formations were the main threads of the analytic substrate of the investigation. With this articulation, theses threads appear as developers of processes leading to a major approximation of the thought on the identity/alterity dialectical pair of the participants involved. The language within this plot had a decisive importance in all the moments of the search of signification, embracing and connecting the identification/alterative processes, the pedagogical practice of Art and the knowledge shared. In such processes involving (de) (re) construction, one can notice a close correlation of the triad social identity, pedagogical practice and knowledge shared. For this reason, the vigotskian, guetmanovian and kopnian theoretizations were the major framework for the analysis of conceptual formulations; and, as for discourse analysis, Baktin and Orlandi were our masters. For these teachers, the experience shared throughout the process of this typology of tri-axial investigation focused the experience of many theoretical and practical assumptions. Such an experience enabled them to state that this, with collaboration, can make reflection on the practice a starting and promoting element, within the individual level of self-management, in addition to being a space of (de)(re)construction of meanings, of knowledge and of reinvention per se

Sistema inteligente para determinação das direções de chegada de múltiplos sinais em arranjos de antenas

This dissertation presents a new proposal for the Direction of Arrival (DOA) detection problem for more than one signal inciding simultaneously on an antennas array with linear or planar geometry by using intelligent algorithms. The DOA estimator is developed by using techniques of Conventional Beam-forming (CBF), Blind Source Separation (BSS), and the neural estimator MRBF (Modular Structure of Radial Basis Functions). The developed MRBF estimator has its capacity extended due to the interaction with the BSS technique. The BSS makes an estimation of the steering vectors of the multiple plane waves that reach the array in the same frequency, that means, obtains to separate mixed signals without information a priori. The technique developed in this work makes possible to identify the multiple sources directions and to identify and to exclude interference sources
