Elementos teóricos y prácticos de la pedagogía crítica: más allá de la educación, metáfora, escena y experiencia

Este texto aborda de manera crítica los linajes de la pedagogía crítica en la propuesta de la Escuela de Frankfurt - Adorno, Horkheimer, Benjamín, Marcuse y Fromm-, tanto en la propuesta de Paulo Freire como en la de contemporáneos que continúan reflexionando y construyendo saberes y prácticas pedagógicas críticas, como lo son Henry Giroux o Peter McLaren. Los autores del artículo sugieren que el fundamento de la propuesta de una pedagogía crítica comienza por reivindicar al sujeto y las formas de este de resistirse, emanciparse y liberarse, ante un sistema homogenizador y deshumanizante.

Trajectory Privacy Preservation in Mobile Wireless Sensor Networks

In recent years, there has been an enormous growth of location-aware devices, such as GPS embedded cell phones, mobile sensors and radio-frequency identification tags. The age of combining sensing, processing and communication in one device, gives rise to a vast number of applications leading to endless possibilities and a realization of mobile Wireless Sensor Network (mWSN) applications. As computing, sensing and communication become more ubiquitous, trajectory privacy becomes a critical piece of information and an important factor for commercial success. While on the move, sensor nodes continuously transmit data streams of sensed values and spatiotemporal information, known as ``trajectory information". If adversaries can intercept this information, they can monitor the trajectory path and capture the location of the source node. This research stems from the recognition that the wide applicability of mWSNs will remain elusive unless a trajectory privacy preservation mechanism is developed. The outcome seeks to lay a firm foundation in the field of trajectory privacy preservation in mWSNs against external and internal trajectory privacy attacks. First, to prevent external attacks, we particularly investigated a context-based trajectory privacy-aware routing protocol to prevent the eavesdropping attack. Traditional shortest-path oriented routing algorithms give adversaries the possibility to locate the target node in a certain area. We designed the novel privacy-aware routing phase and utilized the trajectory dissimilarity between mobile nodes to mislead adversaries about the location where the message started its journey. Second, to detect internal attacks, we developed a software-based attestation solution to detect compromised nodes. We created the dynamic attestation node chain among neighboring nodes to examine the memory checksum of suspicious nodes. The computation time for memory traversal had been improved compared to the previous work. Finally, we revisited the trust issue in trajectory privacy preservation mechanism designs. We used Bayesian game theory to model and analyze cooperative, selfish and malicious nodes' behaviors in trajectory privacy preservation activities.

Call recognition and individual identification of fish vocalizations based on automatic speech recognition: An example with the Lusitanian toadfish

The study of acoustic communication in animals often requires not only the recognition of species specific acoustic signals but also the identification of individual subjects, all in a complex acoustic background. Moreover, when very long recordings are to be analyzed, automatic recognition and identification processes are invaluable tools to extract the relevant biological information. A pattern recognition methodology based on hidden Markov models is presented inspired by successful results obtained in the most widely known and complex acoustical communication signal: human speech. This methodology was applied here for the first time to the detection and recognition of fish acoustic signals, specifically in a stream of round-the-clock recordings of Lusitanian toadfish (Halobatrachus didactylus) in their natural estuarine habitat. The results show that this methodology is able not only to detect the mating sounds (boatwhistles) but also to identify individual male toadfish, reaching an identification rate of ca. 95%. Moreover this method also proved to be a powerful tool to assess signal durations in large data sets. However, the system failed in recognizing other sound types.

A stakeholder perspective on heritage branding and digital communication

How does an archaeological museum understand its function in a digital environment? Consumer expectations are rapidly shifting, from what used to be a passive relationship with exhibition contents, towards a different one, in which interaction, individuality and proactivity define the visitor experience. This consumer paradigm is much studied in fast moving markets, where it provokes immediately measurable impacts. In other fields, such as tourism and regional development, the very heterogeneous nature of the product to be branded makes it near to impossible for only one player to engage successfully. This systemic feature implies that museums, acting as major stakeholders, often anchor a regional brand around which SME tend to cluster, and thus assume responsibilities in constructing marketable identities. As such, the archaeological element becomes a very useful trademark. On the other hand, it also emerges erratically on the Internet, in personal blogs, commercial websites, and social networks. This forces museums to enter as a mediator, authenticating contents and providing credibility. What might be called the digital pull factor poses specific challenges to museum management: what is to be promoted, and how, in order to create and maintain a coherent presence in social media? The underlying issue this paper tries to address is how museums perceive their current and future role in digital communication.

Progress in analytical approaches integrating Livestock and Biodiversity to identify HNV Montados

The World Congress Silvo-Pastoral Systems 2016 aims to gather researchers from different disciplines, practitioners and policy makers at different governance levels that deal with the management and sustainability of silvo-pastoral systems. In this way the congress will create a fertile context to progress through interdisciplinarity research approaches that can help translate scientific knowledge into new adaptive management solutions, and thus bridge from science to practice. The aim is also to gather and compare knowledge from silvo-pastoral systems around the world, which share drought as a limiting factor, so that they can be discussed and evaluated.

Gestão democrática caminhos e possibilidades : um estudo de caso em uma escola pública de ensino fundamental em Belém

A linha de pesquisa desenvolvida nesta dissertação não é inédita, todavia, apresenta algumas peculiaridades a respeito da gestão democrática para a educação brasileira, mais especificamente em Belém do Pará, que são no mínimo, um contributo à sociedade. Principalmente porque demonstra sucintamente, no primeiro e segundo capítulos a trajetória sócio histórica e a política-pedagógica da gestão democrática no Brasil a partir dos meados do século XVI, até a implementação da LDB nº 9394/96. No terceiro capítulo trato a respeito das Leis de Diretrizes e Bases da Educação Nacional, nº 5692/71 e da LDB nº 9394/96, esta última objetivou romper com os resquícios deixados pela 5692/71, vale frisar que o primeiro estado a implementar as Leis de Diretrizes e Bases, assentadas na Lei nº 9394/96, foi o estado do Pará. Nos capítulos: quarto e quinto destaco a Metodologia aplicada à pesquisa de campo; às análises dos dados coletados e mensurados, e construo uma triangulação e/ou cruzamento (Teoria-Práxis-Teoria que resultará à práxis), entre a teoria pesquisada e analisada, com as referências bibliográficas e com os dados coletados no campo acerca dos caminhos e possibilidades necessários para articular a gestão democrática no município de Belém. Para construir esse trajeto recorri às leituras bibliográficas de autores que já aprofundaram o assunto como: José Júlio Chiavenato, Luiz Fernando Dourado, Paulo Freire, Moacir Gadotti, Carlos Libâneo, João Monlevad, Vítor Paro, Michel Thiollent, Sofia Lérché Vieira entre outros autores que contribuíram para a construção teórica e prática, e que estão citados na referência. No que concerne a pesquisa de campo foi efetivada uma sondagem prévia e uma apresentação do tema à direção da escola e para a presidente do Conselho Escolar, em seguida foram feitos contatos com os profissionais da educação através de conversas informais a cerca do assunto. Após esse processo foram aplicados questionários com vinte e seis perguntas objetivas e duas perguntas subjetivas, que estão expostas no anexo desta dissertação; outros mecanismos utilizados na pesquisa de campo foram as entrevistas in lócus com alguns profissionais da escola pesquisada, utilizou-se também a observação participante com o viés na abordagem sócio histórica. O trabalho de campo e as referências bibliográficas coadunadas à observação participante, no cotidiano da comunidade escolar, foram essenciais para a consolidação deste trabalho dissertativo que envolveu um tema, que certamente, está em voga na educação brasileira e que serviu como base para o título desta dissertação: Gestão democrática caminhos e possibilidades:. Um estudo de caso em uma escola pública de ensino fundamental em Belém. A dissertação em questão também apresenta no capítulo quinto o tripé básico para a análise científica relacionada a gestão democrática que são: Eleição direta para o Conselho Escolar, eleição direta para o diretor/articulador/social, eleição para o grêmio estudantil, esta sob a direção dos alunos. A base desse tripé deve estar assentada na participação qualitativa de todas as categorias da comunidade escolar, preservando e respeitando a autonomia de cada categoria, bem como demonstra a aproximação e a contribuição da comunidade externa para o processo de ensino-aprendizagem. E, por fim, não menos importante, proponho algumas sugestões que estão expostas nas conclusões e demonstram claramente a necessidade de implementação de alguns caminhos a serem seguidos e implementados para que de fato e de direito se processe a gestão democrática participativa, à luz dos conceitos apresentados nesta dissertação que estão diretamente relacionados à formação, à participação, e à autonomia, para isso é necessário alguns ajustes na lei nº 7.722/94, na resolução nº036/2008 e o conhecimento e domínio da Lei nº 9394/96.__ ABSTRACT: The line of research developed in this thesis is not new, however, presents some peculiarities about the democratic management in Brazilian education, specifically in Belem, which are at least a contribution to society. Mainly because it shows succinctly in the first and second chapters the history and socio-historical political-pedagogical democratic management in Brazil since the mid-sixteenth century through implementation of the LDB 9394/96. ln the third chapter dealing with respect to the Laws of Directives and Bases of National Education, 5692/71 and 9394/96 LDB, the latter aimed to break with the remnants left over from 5692/71, it is worth stressing that the first state to implement the laws Guidelines and Bases, sitting in the Law 9394/96, was the Para The fourth and fifth chapters highlight the Methodology applied to field research, the analysis of data collected and measured and construct a triangulation and I or intersection (Theory-Praxis-Theory resulting praxis), between theory researched and analyzed with the references and the data collected in the field about the ways and possibilities necessary to articulate the democratic management at the education system in the municipality of Belém. To construct this path resorted to reading literature by authors who have explored the subject as: Jose Julio Chiavenato, Luiz Fernando Dourado, Paulo Freire, Moacir Gadotti, Carlos Libâneo John Monlevade, Paro Vítor, Michel Thiollent, Sofia Lerche Vieira and others who contributed to the theoretical and practical construction andare cited in the reference. Regarding the field research, it was carried a survey and a preliminary presentation of the theme to the school principal and to the School Board president, then were made contacts with professionals in education, through informal conversations about the subject. After this procedure were applied questionnaires with twenty-six objective questions and two subjective questions that are exposed in the appendix of this thesis. Other mechanisms used in field research were interviews in locus with some professionals of the surveyed. It was also used participant observation with the bias in the socio-historical approach. The field research and the references link ed to the participant observation in daily school community. were essential for the consolidation of this dissertational work involving a theme, which certainly, is in vogue in the Brazilian education and That served as the basis for this title dissertation: Management democratic ways and possibilities: A in a public elementary school case study in Belém. This dissertation Thesis presents in Its fifth chapter the basic tripod for scientific analysis related to the democratic management which are: Direct election for the School Board, direct election for chief articulator/social, for students union, this last one under the direction of the students. The basis of this tripod must be seated in the qualitative participation of all categories of the school community, preserving and respecting the autonomy of each on and demonstrates the approach and the contribution of the externa! community to the process of teaching and learning. At finally, but not less important propose some suggestions that are exposed on the conclusion and clearly demonstrate the need to implement some ways to be followed and implemented so that actually and by law the participatory democratic management, may be conducted according to Ulrich the concepts of this dissertation, are directly related to education, participation, and autonomy. However, this requires some adjustments in the Law 7.722/94, in its resolution 036/2008, and indeed the knowledge mastery of the Law 9394/96.
