Nuestro hombre del 98.

Dos rasgos importantes de la generación del 98 se observan en José Martí: uno es su preferencia por el ensayo y esa preferencia se abre espacio dentro del gran crecimiento del periodismo moderno. Hizo de su periodismo un gran ensayismo de gran porte crítico y artístico. Los del 98 no fueron ninguno hombres de acción, pero si Martí hasta el extremo de morir por su causa. Está en contra de esta guerra del sistema colonial español (nunca contra el pueblo español), como contra el colonialismo americano. Por todo ello, pude afirmarse que el único cubano preparado para afrontar política y culturalmente el viraje histórico del 98 fue el mismo, cuya muerte tres años antes fue tan trágica como involuntario había facilitado aquel viraje. Había presentido la intervención de Cuba por Estados Unidos. Choca también la ausencia en términos generales del tema norteamericano en la generación del 98. pudo ser por el trauma interno, salvo en Ortega que este tema no desapareció. Sin embargo, los cubanos del 98 y sus descendientes, en cambio, no han podido olvidar la amenaza que José Martí previó como peligro consciente para Cuba. En los umbrales del tercer milenio, el nuevo 98 se nos presenta como amplificación a nivel planetario de lo que empezó con la explosión del Maine enla bahía de la Habana. Ya no hay enmienda, ni suspense, ni alternativa. El todo poderoso imperio norteamericano sigue salvando el mundo. Los marines son el ejército de salvación mundial.

Underwater slam for estructured environments using and imaging sonar

Aquesta tesi tracta sobre el problema de la navegació per a vehicles submarins autònoms que operen en entorns artificials estructurats com ara ports, canals, plataformes marines i altres escenaris similars. A partir d'una estimació precisa de la posició en aquests entorns, les capacitats dels vehicles submarins s'incrementen notablement i s'obre una porta al seu funcionament autònom. El manteniment, inspecció i vigilància d'instal lacions marines són alguns exemples de possibles aplicacions. Les principals contribucions d'aquesta tesi consisteixen per una banda en el desenvolupament de diferents sistemes de localització per a aquelles situacions on es disposa d'un mapa previ de l'entorn i per l'altra en el desenvolupament d'una nova solució al problema de la Localització i Construcció Simultània de Mapes (SLAM en les seves sigles en anglès), la finalitat del qual és fer que un vehicle autònom creï un mapa de l'entorn desconegut que el rodeja i, al mateix temps, utilitzi aquest mapa per a determinar la seva pròpia posició. S'ha escollit un sonar d'imatges d'escaneig mecànic com a sensor principal per a aquest treball tant pel seu relatiu baix cost com per la seva capacitat per produir una representació detallada de l'entorn. Per altra banda, les particularitats de la seva operació i, especialment, la baixa freqúència a la que es produeixen les mesures, constitueixen els principals inconvenients que s'han hagut d'abordar en les estratègies de localització proposades. Les solucions adoptades per aquests problemes constitueixen una altra contribució d'aquesta tesi. El desenvolupament de vehicles autònoms i el seu ús com a plataformes experimentals és un altre aspecte important d'aquest treball. Experiments portats a terme tant en el laboratori com en escenaris reals d'aplicació han proporcionat les dades necessàries per a provar i avaluar els diferents sistemes de localització proposats.

Cystoseira-dominated assemblages from sheltered areas in the Mediterranean sea : diversity, distribution and effects of pollution

Les algues del gènere Cystoseira són els principals organismes formadors d'estructura en fons rocosos ben il·luminats del Mar Mediterrani. Formen unes comunitats molt estructurades que s'assemblen ecològicament als boscos terrestres i que són sensibles als impactes antròpics. Aquesta tesi s'ha centrat en l'estudi de les espècies i comunitats dominades per Cystoseira que es troben en ambients calmats, és a dir, en petites cales i/o badies. S'han abordat diversos aspectes com són la distribució, composició, estructura i biogeografia d'aquestes comunitats, així com els efectes de la contaminació sobre les mateixes. Per una banda, s'ha documentat l'estat actual de les comunitats dominades per C. crinita a nombrosos llocs al llarg de tot el Mediterrani, aportant informació sobre la seva composició, estructura, variació biogeogràfica i dinàmica de la comunitat a llarg termini. S'ha documentat la desaparició de diverses espècies de Cystoseira en zones afectades per impactes antròpics diversos i s'ha proporcionat la primera evidència experimental de la desaparició d'espècies de Cystoseira a causa de la contaminació.

As "Confrarias" como um Fenômeno Organizacional Brasileiro: Notas Etnográficas de um Aprendiz de Bourdieu

Over the last years we have seen a significant increase in scholarly production within the organization studies field in Brazil. However it is still not representative. The tendency to consume foreign and fashionable ideas unrestrainedly, to make use of imported, universal and non-contextualized explanations to inquiry phenomenon which are essentially local and particular, make it difficult to develop a true Brazilian tradition. This work is a result of an ambitious ethnographic adventure" of an acknowledged apprentice of sociologist Pierre Bourdieu's large body of knowledge. It is about taking reflexivity to the limit. It is about learning "through the body" in an effort - both theoretical and empirical - to investigate a Brazilian organizational phenomenon which reproduces the hierarchical side of our society and, under the disguise of the legitimacy offered by organizational discourse, help keeping the very structure of our society in a silent but powerful way. I also want this work to be an alert for the importance of contextualization as a means to avoid a recurring distortion of the scholarly production in administrative science: the mobilization of theoretical references in such a safe way that make explicitness totally unnecessary, the appropriation of concepts whose essence is strange to the nature of the very phenomenon which they aim to explain, and the insistence in the impersonal style, in third-voice narratives, as if it were possible to produce knowledge in social sciences with absolute impartiality.

Prototexto, narrativa poética da ciência: uma estratégia de construção do conhecimento e religação de saberes no ensino de física

In this thesis I present the prototexto notion and to I base as a complex system while strategy of knowledge construction and reconexion of you know in physics teaching. Prototexto is a poetic narrative of the science, proposal and used initially as "instrument of creative" learning for students apprentice of science of the medium and technical teaching of the Vitória da Conquista's CEFET-BA, in the period of 1997-2004. Later become pregnant as a strategy of knowledge construction, in the Universidade Estadual da Bahia - UESB, the prototexto notion configures a complement to the mathematical formulation. The proposal of a poetic narrative of the science is that the apprentice of science starts to organize in an aesthetic-literary way your knowledge, dispersed in disciplines, starting from a theme of the physics. The prototexto emerges of my reflections concerning the classic science, identified for Edgar Morin as tends a thought excessively numeric, and that it has been reproduced in physics teaching, in most of the schools, limiting him/it to an order pattern with the mistake absence. They are operations of the prototexto: the poetic language, the pedagogic stamp, the unfinished of the argument, the system character and the apprentice's of science inclusion as subject implicated in the construction of the knowledge. the theoretical foundations are based Morin's proposition of the method as strategy, the beginning of the complementarity of Niels Bohr in conceiving excluding categories as face of a same phenomenon and the conception of creative time of Ilya Prigogine that enunciates the alliance among the nature and the man that it describes her

Reflexões sobre a construção e evolução de conceitos geométricos nas séries intermediárias do ensino fundamental

This thesis represents a didactic research linked to the Post-graduation Programme in Education of the Universidade Federal do Rio Grande do Norte which aimed to approach the construction of the geometrical concepts of Volume of the Rectangular Parallelepiped, Area and Perimeter of the Rectangle adding a study of the Area of the Circle. The research was developed along with students from the 6th level of the Elementary School, in a public school in Natal/RN. The pedagogical intervention was made up of three moments: application of a diagnostic evaluation, instrument that enabled the creation of the teaching module by showing the level of the geometry knowledge of the students; introduction of a Teaching Module by Activities aiming to propose a reflexive didactic routing directed to the conceptual construction because we believed that such an approach would favor the consolidation of the learning process by becoming significant to the apprentice, and the accomplishment of a Final Evaluation through which we established a comparison of the results obtained before and after the teaching intervention. The data gathered were analyzed qualitatively by means of a study of understanding categories of mathematical concepts, in addition to using descriptive statistics under the quantitative aspect. Based on the theory of Richard Skemp, about categorization of mathematical knowledge, in the levels of Relational and Instrumental Understanding were achieved in contextual situations and varied proportions, thus enabling a contribution in the learning of the geometrical concepts studied along with the students who took part in the research. We believe that this work may contribute with reflections about the learning processes, a concern which remained during all the stages of the research, and also that the technical competence along with the knowledge about the constructivist theory will condition the implementation of a new dynamics to the teaching and learning processes. We hope that the present research work may add some contribution to the teaching practice in the context of the teaching of Mathematics for the intermediate levels of the Elementary School

Universo encantado do cuidado na autopoiese docente: uma viagem epistemológica transdisciplinar

The health transition experienced in Brazilian health care model requires a metamorphosis in human and society, placing new demands on health and education. The Faculty of Science, Culture and Extension of Rio Grande do Norte (Facex), aware of their responsibilities to the Health System, which brings the principle of comprehensiveness as its structural axis, dared to implement a course of nursing in complex thinking and Experiential Pedagogy Humanescente with curriculum inter / transdisciplinary. For deployment of proprosta was not enough to reform thinking of educators, there was a need corporalizar new teaching practices that are aimed at the integral formation of human beings. In this context, emerged the workshop on Human Education autopoietic, self-forming area of the educator, where he developed an Action Research Existential (PA-E) which enabled experience, describe and analyze how the human autopoietic educators could contribute to the practice educational humanescente transdisciplinary curriculum project. Were worked out in meetings, knowledge necessary to practice the transdisciplinary 1st Meeting - learn to create; 2nd Meeting - learn to recognize the laws of nature with emphasis on complexity theory, 3rd Meeting - learn to organize, 4th meeting - namely autoestruturar themselves; 5th Meeting - know how to choose, 6th Meeting - knowing innovate 7th Meeting - namely exchange. Next an autobiographical perspective, we chose the metaphorical possibility to narrate the ways and strategies covered by the author and apprentice in the company of the Little Prince de Saint-Exupery, in search of a sensible pedagogical practice complex, which promotes re-enchant transdisicplinar education. The route involved five methodological connections: a literature review which relate to training for care in undergraduate nursing: the study of learning processes that drive the formation humanopoiética, emphasizing the relationship that involves the complexity and embodiment in the educational process transdisciplinary, highlighting the analysis of what is to learn from the findings of biosciences and recent cognitive theories of Maturana and Varela, the description of the interdisciplinary curriculum of the nursing course of Facex and Training Workshop, Human autopoietic, with emphasis on Experiential Education Humanescente; the report of seven meetings of the Workshops (cocoon), recording the experiences and listening to educators (luminescent butterflies), the final reflections with learning opportunized. Experientiality lived through, the expressions and words, educators say the influence of workshops for their teaching practices, highlighting it as a space for selforganizing, creating, learning and enchantment, and can identify the workshop as a place of transformation necessary for deployment an interdisciplinary curriculum. The knowledge emerging from the study indicate the need for permanent spaces of self, in which the educator learns from its body, between cognitive processes and vital, and in the experiences of their formative process the opportunity to act on the dimensions of knowing and being

Dimensões didática, afetiva e formativa de docência que tecem as representações sociais entre licenciandos da UFPI

This study intends to analyze the social representation of teaching for students of first years of undergraduate courses in Education, Letters and Biology. The field of this research was the Federal University of Piaui - Campus of Picos in 2009. To reach the objective proposed above, was used the theory of social representations to the seizure of the elements which constitute such representations according to Moscovici and colleagues, considering the contribution of Abric with his Theory of Central Nucleus and Wagner with the Theory of Sociogenesis. Data were collected in two phases: first, through the Technique of Free Association of Words (TFAW) of which 100 subjects evoked representations of their teaching through the inductor terms 'to teach', 'student' and 'teacher'. For those data we used the EVOC software that promoted to detect the elements of the core and to conclude that the social representation of teaching is one of the work performed by a master / teacher who transmits, directed to an apprentice who learns, confined to the school involving the student with all his virtues to be smart, interested and dedicated, and teacher to be friend, wise bearer of knowledge and also intelligent. Then, using the Multiple Classification Procedure (MCP) only 10 subjects made ratings of 25 more evoked words in the first phase, for the analysis of data from the MPC with the use of the SPSS software we used Multidimensional Statistical Analysis (MSA) for the Free Classification we found three dimensions of Social Representation of Teaching: The Didactic, that focuses on teacher and student being superimposed, meaning the inseparability of these elements, the Affective, which presents the elements inherent in teachers with love as the strong point of this dimension, and the Formative, that is as ambiguous as ambivalent because it sees the teacher as a professional directed to help students get an education; for Directed Classification with Similarity Structure Analysis (SSA), we learn that teaching is a profession that materializes in the classroom, which is extremely true because the action happens in this teaching space, supposing a caring, loving, cheerful, capable, apt, patient, partner, responsible, dedicated, committed educator, who has wisdom and knows how to teach and help students through dialogue to there study and learning. All of it s necessary to occur the result of teaching, which is education in a disciplinary manner. The results point to a very traditional social representation of what is the role of teachers, the role of students and the role of the relationship itself between teaching and learning through the act of teaching. With this statement, we can confirm that the structure of Social Representation of Teaching for the investigated subjects reflects the sociogenetic conditions that engendered them, and that these conditions permeate their structural organization, in particular time-context in which social representation was captured

"Eu pensei que ia sair daqui falando inglês": um estudo sistêmico-funcional sobre papéis sociais atribuídos por alunos de um curso de Letras/Inglês

Research in the area of teacher training in English as a Foreign Language (CELANI, 2003, 2004, 2010; PAIVA, 2000, 2003, 2005; VIEIRA-ABRAHÃO, 2010) articulates the complexity of beginning teachers classroom contexts aligned with teaching language as a social and professional practice of the teacher in training. To better understand this relationship, the present study is based on a corpus of transcribed interviews and questionnaires applied to 28 undergraduate students majoring in Letters/English emphasis, at a public university located in the interior of the Western Amazon region, soliciting their opinions about the reforms made in the curriculum of this Major. Interviews and questionnaires were used as data collection instruments to trace a profile of the students organized in Group 1, with freshmen and sophomore undergraduates who are following the 2009 curriculum, and Group 2, with junior and senior undergraduates who are following the 2006 curriculum. The objectives are to identify, to characterize and to analyze the types of pronouns, roles and social actors represented in the opinions of these students in relation to their teacher training curriculum. The theoretical support focuses on the challenge of historical and contemporary routes from English teachers initial education programs (MAGALHÃES; LIBERALLI, 2009; PAVAN; SILVA, 2010; ALVAREZ, 2010; VIANA, 2011; PAVAN, 2012). Our theoretical perspective is based on the Systemic Functional Grammar of Halliday (1994), Halliday and Hasan (1989), Halliday and Matthiessen (2004), Eggins (1994; 2004) and Thompson (2004). We focus on the concept of the Interpersonal meaning, specifically regarding the roles articulated in the studies by Delu (1991), Thompson and Thetela (1995), and in the Portuguese language such as Ramos (1997), Silva (2006) and Cabral (2009). Moreover, we ascribe van Leeuwen s (1997; 2003) theory of Representation of Social Actors as a theoretical framework in order to identify the sociological aspect of social actors represented in the students discourse. Within this scenario, the analysis unfolds on three levels: grammatical (pronouns), semantic (roles), and discursive (social actors). For the analysis of interpersonal realizations present in the students opinions, we use the computational program WordSmith Tools (SCOTT, 2010) and its applications Wordlist and Concord to quantify the occurrences of the pronouns I, You and They, which characterize the roles and social actors of the corpus. The results show that the students assigned the following roles to themselves: (i) apprentice to express their initial process of English language learning; (ii) freshman to reveal their choice of Major in Letters/English emphasis; (iii) future teacher to relate their expectations towards a practicing professional. To assign the roles to professors in the major, the students used the metaphor of modality (I think) to indicate the relationship of teacher training, while they are in the role of a student and as a future teacher. From these evidences the representation of the students as social actors emerges in roles such as: (i) active roles; (ii) passive roles and (iii) personalized roles. The social actors represented in the opinions of the students reflect the inclusion of these roles assigned to the actions expressed about their experiences and expectations derived from their teacher training classroom

O estudo das funções quadráticas e sua relação com o cotidiano

Across the centuries, Mathematics - exact science as it is - has become a determining role in the life of man, which forms to use suprir needs of their daily lives. With this trajectory, is characterized the importance of science as an instrument of recovery not only conteudstica, but also a mathematician to know that leads the apprentice to be a dynamic process of learning ecient, able to find solutions to their real problems. However, it is necessary to understand that mathematical knowledge today requires a new view of those who deal directly with the teaching-learning process, as it is for them - Teachers of Mathematics - desmistificarem the version that mathematics, worked in the classroom, causes difficulties for the understanding of students. On this view, we tried to find this work a methodology that helps students better understand the Quadratic functions and its applications in daily life. Making use of knowledge Ethnomathematics, contextualizing the problems relating to the content and at the same time handling the software GeoGebra, aiming a better view of the behavior of graphs of functions cited
