Déficit abrangência nas narrativas da contemporaneidade

O artigo analisa as narrativas da contemporaneidade, na vertente da reportagem, e cruza as práticas jornalísticas com o discurso científico da complexidade. Do intercâmbio inter e transdisciplinar, apresenta os desafios epistemológicos vivenciados nas mediações sociais da comunicação. Dessa forma, o presente texto desliza constantemente entre as narrativas das mídias brasileiras contemporâneas sobre temas emergentes e os suportes teóricos que desenvolveu em sua obra. Apontando as dinâmicas empíricas e a crise dos paradigmas teóricos, o artigo apresenta, ainda, um diagnóstico do deficit de complexidade nas práticas interpretativas da experiência coletiva.

A new Pennsylvanian Oriocrassatellinae from Brazil and the distribution of the genus Oriocrassatella in space and time

Oriocrassatella Etheridge Jr., 1907 is a long range crassatellid bivalve genus well recognized in shallow waters of epeiric seas throughout the upper part of Paleozoic. The first occurrences of this genus are recorded in the sedimentary successions of the Gondwana, both in Australia and South America. However, the geographic and age distribution of Oriocrassatella in Late Mississippian deposits of Australia and Argentina may indicate an earliest Visean or even a pre-Visean origin for the genus. Following its origin in Early Carboniferous a complex paleobiogeographic history from Southern to Northern Hemisphere took place in the Permian. During its initial dispersal phase from Late Carboniferous to the Early Permian the genus thrived in cold water environments associated to the Late Paleozoic Gondwana glaciation. Shallow-water bottoms of the warm waters of the central Gondwana fringe and Laurussia were colonized by Oriocrassatella only during Early Permian times when the genus became cosmopolitan. A new species of this genus is described herein, Oriocrassatella piauiensis n. sp., recorded from the Piaui Formation, Pennsylvanian of the Parnaiba Basin. This new species may represent an early adaptation to warm waters. However, based on available data, species of this genus seem to have adapted definitely to warm water environments probably related the Late Pennsylvanian interglacial phases. In these phases, climatic barrier were interrupted allowing the faunal interchange and larval dispersion following a South to North migration route through the eastern margins of Gondwana and the eastern Paleotethys.

The Panama microplate, island studies and relictual species of Melipona (Melikerria) (Hymenoptera: Apidae: Meliponini)

The endemic stingless honey-making bee Melipona (Melikerria) insularissp.n. on Coiba and Rancheria Islands in Pacific Panama is described, together with the proposed sister species, M. ambigua sp.n. from northeast Colombia. The Coiba Island group and Panama mainland were surveyed, yielding one meliponine endemic (M. insularissp.n.) and six meliponine genera and species. The poor Coiba fauna of amphibians and birds corresponds to the poor social bee fauna and suggests habitat barriers generally precluded recolonization from the mainland during glacial periods. Many animals became extinct, yet some remain as relicts. Melipona insularissp.n. was isolated on accreted terranes of Coiba rainforest in the Panama microplate. Morphology suggests that M. insularissp.n. is not a direct descendant of the San Blas-E. Panama endemic Melikerria, M. triplaridis. A phylogenetic hypothesis corroborates disjunct distributions. Rainforest endemics such as Peltogyne purpurea (Fabaceae) and Ptilotrigona occidentalis (Apidae, Meliponini) also occur as relictual, disjunct populations in Central and South America. These may have been isolated before accelerated biotic exchange began 2.4 Ma. Our work supports the geological findings of both a volcanic arc and the San Blas massif providing a substantial bridge for Melikerria from Colombia and Panama in Eocene to Miocene times. We suggest there have been taxon cycles permitting recolonization during glaciations, whereby colonies of M. insularissp.n. were able to recolonize Rancheria, a 250 ha island, 2 km from Coiba. However, rafting colonies nesting in trees, carried on vegetation mats, may have produced founding populations of Melipona in Central America and on oceanic islands such as Coiba.

MARC 21 e XML como ferramentas para a consolidação da catalogação cooperativa automatizada: Uma revisão de literatura

The cooperation and the sharing of information cataloguing and bibliographical in environment automated, this was only possible with the creation and adoption of interchange format MARC21. But due to the progresses of the technologies of information and communication, of the crescent use of Internet and of the databases and databanks, there were the need of the creation and development of tools that optimize the organization activities, retrieval and interchange of information. XML is one of those developments that have as purpose to facilitate the management, storage and transmission of data through Internet. Before that, it was proposed through a literature revision, to analyze Interchange Format MARC21 and Markup Language XML as tools for the consolidation of the Automated Cooperative Cataloguing, your differences of storage flexibilities, organization, retrieval and interchange of data through Internet. This research made possible the divulgation to the community librarian, through a literature revision, that has been discussed internationally on MARC21 and XML

Troca e criação de valor: possibilidades competitivas advindas da estratégia de redes

O compartilhamento de custos e de conhecimento, traduzidos neste trabalho por troca e criação de valor, foi objeto de estudo em duas redes empresariais do varejo alimentício, localizadas na região central do estado do Rio Grande do Sul. O objetivo foi investigar se essas possibilidades competitivas, advindas da estratégia de rede, estão sendo exploradas pelos gestores das empresas associadas. A pesquisa foi conduzida pelo método de estudo de caso, cuja coleta de dados processou-se por meio de visitas in loco acompanhadas de entrevistas com os principais executivos das redes e de questionários para os gestores das empresas associadas. Como resultado, pôde-se perceber que ambas exploram com maior ênfase as possibilidades de troca de valor, principalmente nas relações conjuntas de aquisição e relacionamento com clientes, em detrimento dos outros componentes da cadeia de valor. Por outro lado, em termos de criação de valor, verificou-se que existe um ambiente de intensa aprendizagem em ambas as redes, mas evidenciaram-se dificulda- des de efetivar a criação de valor com ações conscientes.

Sicurezza di rete, analisi del traffico e monitoraggio.

Il lavoro è stato suddiviso in tre macro-aree. Una prima riguardante un'analisi teorica di come funzionano le intrusioni, di quali software vengono utilizzati per compierle, e di come proteggersi (usando i dispositivi che in termine generico si possono riconoscere come i firewall). Una seconda macro-area che analizza un'intrusione avvenuta dall'esterno verso dei server sensibili di una rete LAN. Questa analisi viene condotta sui file catturati dalle due interfacce di rete configurate in modalità promiscua su una sonda presente nella LAN. Le interfacce sono due per potersi interfacciare a due segmenti di LAN aventi due maschere di sotto-rete differenti. L'attacco viene analizzato mediante vari software. Si può infatti definire una terza parte del lavoro, la parte dove vengono analizzati i file catturati dalle due interfacce con i software che prima si occupano di analizzare i dati di contenuto completo, come Wireshark, poi dei software che si occupano di analizzare i dati di sessione che sono stati trattati con Argus, e infine i dati di tipo statistico che sono stati trattati con Ntop. Il penultimo capitolo, quello prima delle conclusioni, invece tratta l'installazione di Nagios, e la sua configurazione per il monitoraggio attraverso plugin dello spazio di disco rimanente su una macchina agent remota, e sui servizi MySql e DNS. Ovviamente Nagios può essere configurato per monitorare ogni tipo di servizio offerto sulla rete.

Interpreting Judgements using Knowledge Representation Methods and Computational Models of Argument

The goal of the present research is to define a Semantic Web framework for precedent modelling, by using knowledge extracted from text, metadata, and rules, while maintaining a strong text-to-knowledge morphism between legal text and legal concepts, in order to fill the gap between legal document and its semantics. The framework is composed of four different models that make use of standard languages from the Semantic Web stack of technologies: a document metadata structure, modelling the main parts of a judgement, and creating a bridge between a text and its semantic annotations of legal concepts; a legal core ontology, modelling abstract legal concepts and institutions contained in a rule of law; a legal domain ontology, modelling the main legal concepts in a specific domain concerned by case-law; an argumentation system, modelling the structure of argumentation. The input to the framework includes metadata associated with judicial concepts, and an ontology library representing the structure of case-law. The research relies on the previous efforts of the community in the field of legal knowledge representation and rule interchange for applications in the legal domain, in order to apply the theory to a set of real legal documents, stressing the OWL axioms definitions as much as possible in order to enable them to provide a semantically powerful representation of the legal document and a solid ground for an argumentation system using a defeasible subset of predicate logics. It appears that some new features of OWL2 unlock useful reasoning features for legal knowledge, especially if combined with defeasible rules and argumentation schemes. The main task is thus to formalize legal concepts and argumentation patterns contained in a judgement, with the following requirement: to check, validate and reuse the discourse of a judge - and the argumentation he produces - as expressed by the judicial text.

A Study of the Diffusion of Electroplated Coatings in the Solid State.

The term diffusion means an equalization or homogenization of diverse materials. Specifically ap­plied to metals, diffusion is the interchange of atoms. It is, in effect, an invasion of one crystal lattice by the atoms of one or more other crystal lattices. Therefore, the study of diffusion must involve the geometry and physics of crystal lattices as well as their energies.

Servizi Sociali Territoriali e Università: Esempi di Sinergie Possibili per un Percorso di Qualità

Although – or because – social work education in Italy has for some 15 years now been exclusively in the domain of the university the relationship between the academic world and that of practice has been highly tenuous. Research is indeed being conducted by universities, but rarely on issues that are of immediate practice relevance. This means that forms of practice develop and become established habitually which are not checked against rigorous standards of research and that the creation of knowledge at academic level pays scant attention to the practice implications of social changes. This situation has been made even worse by the dwindling resources both in social services and at the level of the universities which means that bureaucratic procedures or imports of specialisations from other disciplines frequently dominate the development of practice instead of a theory-based approach to methodology. This development does not do justice to the actual requirements of Italian society faced with ever increasing post-modern complexity which is reflected also in the nature of social problems because it implies a continuation of a faith in modernity with its idea of technical, clear-cut solutions while social relations have decidedly moved beyond that belief. This discrepancy puts even greater strain on the personnel of welfare agencies and does ultimately not satisfy the ever increasing demands for quality and accountability of services on the part of users and the general public. Social workers badly lack fundamental theoretical reference points which could guide them in their difficult work to arrive at autonomous, situation-specific methodological answers not based on procedures but on analytical knowledge. Thirty years ago, in 1977, a Presidential Decree created the legal basis for the establishment of social service departments at the level of municipalities which created opportunities for the direct involvement of the community in the fight against exclusion. For this potential to be fully utilized it would have required the bringing together of three dimensions, the organizational structure, the opportunities for learning and research in the territory and the contribution by the professional community. As this did not occur social services in Italy still often retain the character of charity which does not concern itself with the actual causes of poverty and exclusion. This in turn affects the relationship with citizens in general who cannot develop trust in those services. Through uncritical processes of interaction Edgar Morin’s dictum manifests itself which is that without resorting to critical reflection on complexity interventions can often have an effect that totally the opposite to the original intention. An important element in setting up a dynamic interchange between academia and practice is the placement on professional social work courses. Here the looping of theory to practice and back to theory etc. can actually take place under the right organizational and conceptual conditions, more so than in abstract, and for practitioners often useless debates about the theory-practice connection. Furthermore, research projects at the University of Florence Social Work Department for instance aim at fostering theoretical reflection at the level of and with the involvement of municipal social service agencies. With a general constructive disposition towards research and some financial investment students were facilitated to undertake social service practice related research for their degree theses for instance in the city of Pistoia. In this way it was also possible to strengthen the confidence and professional identity of social workers as they became aware of the contribution their own discipline can make to practice-relevant research instead of having to move over to disciplines like psychology for those purposes. Examples of this fruitful collaboration were presented at a conference in Pistoia on 25 June 2007. One example is a thesis entitled ‘The object of social work’ and examines the difficult development of definitions of social work and comes to the conclusion that ‘nothing is more practical than a theory’. Another is on coping abilities as a necessary precondition for the utilization of resources supplied by social services in exceptional circumstances. Others deal with the actual sequence of interventions in crisis situations, and one very interestingly looks at time and how it is being constructed often differently by professionals and clients. At the same time as this collaboration on research gathers momentum in the Toscana, supervision is also being demanded more forcefully as complementary to research and with the same aim of profiling more strongly the professional identity of social work. Collaboration between university and social service filed is for mutual benefit. At a time when professional practice is under threat of being defined from the outside through bureaucratic prescriptions a sound grounding in theory is a necessary precondition for competent practice.

ProFormA: An XML-based exchange format for programming tasks

Unterstützungssysteme für die Programmierausbildung sind weit verbreitet, doch gängige Standards für den Austausch von allgemeinen (Lern-) Inhalten und Tests erfüllen nicht die speziellen Anforderungen von Programmieraufgaben wie z. B. den Umgang mit komplexen Einreichungen aus mehreren Dateien oder die Kombination verschiedener (automatischer) Bewertungsverfahren. Dadurch können Aufgaben nicht zwischen Systemen ausgetauscht werden, was aufgrund des hohen Aufwands für die Entwicklung guter Aufgaben jedoch wünschenswert wäre. In diesem Beitrag wird ein erweiterbares XML-basiertes Format zum Austausch von Programmieraufgaben vorgestellt, das bereits von mehreren Systemen prototypisch genutzt wird. Die Spezifikation des Austauschformats ist online verfügbar [PFMA].

Speech Intelligibility in Noise With a Single-Unit Cochlear Implant Audio Processor.

INTRODUCTION The Rondo is a single-unit cochlear implant (CI) audio processor comprising the identical components as its behind-the-ear predecessor, the Opus 2. An interchange of the Opus 2 with the Rondo leads to a shift of the microphone position toward the back of the head. This study aimed to investigate the influence of the Rondo wearing position on speech intelligibility in noise. METHODS Speech intelligibility in noise was measured in 4 spatial configurations with 12 experienced CI users using the German adaptive Oldenburg sentence test. A physical model and a numerical model were used to enable a comparison of the observations. RESULTS No statistically significant differences of the speech intelligibility were found in the situations in which the signal came from the front and the noise came from the frontal, ipsilateral, or contralateral side. The signal-to-noise ratio (SNR) was significantly better with the Opus 2 in the case with the noise presented from the back (4.4 dB, p < 0.001). The differences in the SNR were significantly worse with the Rondo processors placed further behind the ear than closer to the ear. CONCLUSION The study indicates that CI users with the receiver/stimulator implanted in positions further behind the ear are expected to have higher difficulties in noisy situations when wearing the single-unit audio processor.

Intercambio científico tecnológico : un proyecto concretado

En el marco del Programa de Cooperación Internacional con UFZ de Leipzig-Halle, Alemania y el apoyo de SECYT, UNCuyo, el CIFOT realiza (1998) el “ Atlas Socioeconómico y Demográfico de los Departamentos del Gran Mendoza" , titulado "Atlas Social de la Ciudad de Leipzig" en Alemania. Tienen como objetivo la generación de Bancos de Datos (tecnología GIS) para el análisis estadístico de indicadores seleccionados y elaboración de Cartografía base y temática. Para su elaboración se forma un equipo de trabajo interdisciplinario que apartan al sistema diferentes visiones del mismo tema. Consta de 3 partes: introducción con características de las zonas en estudio, otra parte con incorporación de mapas y una tercera que es la traducción al inglés del texto. Ambos Atlas resultaron ser elementos de gran utilidad en la planificación territorial de un área como el Gran Mendoza, de fuerte presencia frente al Mercosur, y de Liepzig, ciudad europea en transformación desde 1990.

Comentarios y conclusiones II Seminario Internacional : la interdisciplina en el ordenamiento territorial

Por el éxito y trascendencia de sus eventos anteriores, el Instituto CIFOT siente la obligación de hacer conocer las principales conclusiones del II Seminario de Ordenamiento Territorial, el que comienza a marcar pautas a partir de las preocupaciones comunes, enfoques teórico-metodológicos prevalecientes en el Ordenamiento Territorial, la planificación Estratégica y Ambiental, como también sobre las prácticas de gestión de la información territorial. Se sintetiza la idea central de las conferencias Magistrales: - Dr. Juan Gastó- Pontificia Universidad Católica de Chile- presenta “ La Ordenación Territorial como eje del Desarrollo Rural", cuyo punto central es la imposibilidad de separar la problemática territorial urbana de la rural. - Dr. Eduardo Salinas- Universidad de La Habana , Cuba- en “El Ordenamiento Territorial como instrumento de la Planificación y Gestión Ambiental" establece la necesidad de una planificación sustentable ambientalmente, con una concepción sistémica y holística de los problemas. -Dra. Elsa Laurelli -Universidad de La Plata , Argentina- en “Nuevas Tendencias del Ordenamiento Territorial en una Economía de Mercado. Limitaciones y posibilidades" plantea coexistencia de áreas receptoras de IDE vs espacios degradados y con problemáticas sociales y reflexiona sobre el rol del Estado para atenuar los efectos del mercado en el territorio y la sociedad. - Dr. Pablo Ciccolella -UBA-, Argentina. En “ Desafíos y opciones en la Gestión Urbana bajo el Capitalismo Global: Planificación Estratégica y Desarrollo Económico-Territorial" alerta sobre la planificación llave en mano que genera un desarrollo elitista, banal y efímero. - Dr. Mariano Zamorano -Universidad Nacional de Cuyo, Mendoza- presenta “ Una propuesta de Regionalización de la Provincia de Mendoza sobre la base de la Lógica Territorial " destinada a optimizar la gestión municipal y provincial. Al II Seminario de Ordenamiento Territorial concurren alrededor de 140 personas y se exponen 43 trabajos en las siguientes áreas temáticas : - 1 Nuevas tendencias en el Ordenamiento territorial . - 2 Ambiente y Ordenamiento Territorial. - 3 El Ordenamiento Territorial en el ámbito urbano. - 4 El Ordenamiento Territorial en el ámbito rural. - 5 La gestión de la información en el Ordenamiento Territorial. - 6 El rol de las Instituciones en el Ordenamiento Territorial. Conclusiones De l rico debate e intercambio de ideas realizado durante el II Seminario, se extraen tres grandes temas: - La necesidad de una visión general y holística del territorio, evitando la fragmentación disciplinar. - La interdisciplina, como campo de convergencia de problemáticas complejas. La planificación estratégica como instancia participativa y visión integral del territorio. - La metodología para el Ordenamiento Territorial debe ser verdaderamente aplicada. No se puede seguir planificando con una racionalidad limitada en busca de una imagen objetivo rígida mientras el territorio, conformado por sistemas complejos y abiertos, está en constante cambio por exigencias propias de lo global. - Un Estado en retirada no contiene la estructura necesaria ni el consenso para imponerse en sociedades democráticas con dominio absoluto de tipo capitalista.

La mediación cultural de círculo de lectores : las greguerías de Ramón Gómez de la Serna ilustradas por Antonio Saura (1989)

Círculo de Lectores, club del libro español, ha desarrollado –desde su creación en 1962 y, en particular, bajo la dirección de Hans Meinke entre 1981 y 1997– un proyecto cultural basado tanto en la calidad de la edición de obras de referencia como en la proyección social de su actividad a través de conferencias y exposiciones. Así, Meinke conformó en torno a él una red de artistas, escritores e intelectuales que le condujo a erigirse en uno de los mediadores culturales más relevantes en la España de la segunda mitad del siglo XX. Como consecuencia de una concepción de la cultura como un permanente intercambio entre sus diversas disciplinas, la realización de ediciones ilustradas constituyó uno de los pilares de su política cultural. Dentro de este terreno, fue el pintor Antonio Saura su más estrecho colaborador, no sólo en cuanto a la realización de proyectos, sino asesorando a Meinke en posibles ediciones y recomendando a otros ilustradores. Saura ilustró para Círculo de Lectores los considerados como “libros de su vida", dentro de los cuales la figura de Ramón Gómez de la Serna es una referencia ineludible, al ser su libro Ismos (1931, 1943) una de las lecturas causantes de la vocación artística del pintor. El estudio las condiciones sociales, de circulación y apropiación en Flor nueva de greguerías (1989) servirá como ejemplo del proceso de gestación de proyectos y de interacción de estas redes entre arte y edición.
