Some factors affecting diagnostic accuracy

Diagnosis involves a complex and overlapping series of steps, each of which may be a source of error and of variability between clinicians. This variation may involve the ability to elicit relevant information from the client or animal, in the accuracy, objectivity and completeness of relevant memory stores, and in psychological attributes including tolerance for uncertainty and willingness to engage in constructive self-criticism. The diagnostic acumen of an individual clinician may not be constant, varying with external and personal factors, with different clients and cases, and with the use made of tests. In relation to clients, variations may occur in the ability to gain their confidence, to ask appropriate questions and to evaluate accurately both verbal and nonverbal responses. Tests may introduce problems of accuracy, validity, sensitivity, specificity, interpretation and general appropriateness for the case. Continuing effectiveness as a diagnostician therefore requires constant attention to the maintenance of adequate and up-to-date skills and knowledge relating to the animals and their diseases and to tests, and of sensitive interpersonal skills.

Imagens da escola como mediadoras do processo formativo dos jovens no ensino da arte: di��logos com a hist��ria, mem��ria e ambientes intraescolares

Esta pesquisa apresenta as imagens da escola como mediadoras do processo formativo dos jovens no ensino da Arte em di��logo com a hist��ria, mem��ria e ambientes intraescolares. Inscreve-se no debate produzido pela linha de pesquisa em Educa����o e Linguagens. Analisa a forma����o dos jovens numa turma do terceiro ano do Ensino M��dio na Escola Estadual de Ensino M��dio ���Hunney Everest Piovesan���, localizada no munic��pio de Cariacica no Estado do Esp��rito Santo. O estudo foi realizado em 2013 e tem como objetivo analisar as imagens escolares como mediadoras na forma����o dos estudantes do Ensino M��dio no ensino da Arte em di��logo com a hist��ria, mem��ria e ambientes intraescolares. Ao mesmo tempo, por meio de trabalho colaborativo, contribui para (re)constru����o da hist��ria da institui����o, significando-a junto aos alunos e comunidade escolar. Por meio de interven����o art��stica com imagens da escola prop��e reflex��o cr��tica, analisando a forma����o dos jovens no terceiro ano do Ensino M��dio. Para compreender os conceitos de media����o e meio social, estabelece um di��logo com as obras de Lev Semenovith Vigotski. A partir dos estudos de Maria Ciavatta e Sch��tz���Foerste procura entender a media����o imag��tica e sua dimens��o educativa. Dialoga ainda com Frago, Escolano e Buffa, ampliando as reflex��es sobre os ambientes intraescolares, dimensionando a imag��tica desses espa��os e o senso de pertencimento �� escola a partir da impregna����o pela hist��ria e mem��ria. A investiga����o pauta-se nos referenciais do m��todo qualitativo e colaborativo de pesquisa. A produ����o dos dados contou com o recolhimento e an��lise documental de um conjunto de fontes prim��rias e secund��rias formadas por livro de registro de funcion��rios da escola da d��cada de 1970, di��rios de classe, recortes de jornais, convites de formaturas e registros fotogr��ficos escolares dessa mesma d��cada at�� a atualidade. Al��m desses documentos hist��ricos, foram analisadas entrevistas de antigos alunos e question��rios dos alunos do terceiro ano do Ensino M��dio da institui����o. Relata brevemente experi��ncias de curto interc��mbio acad��mico realizado na Universidade de Ancara, na Turquia, com o objetivo de ampliar os horizontes de refer��ncia sociocultural, em especial com o contexto educacional do Ensino M��dio euroasi��tico, identificando os espa��os de forma����o dos jovens no contexto turco e suas rela����es com a educa����o brasileira. Esta experi��ncia apresentada n��o integra a an��lise desta disserta����o, mas projeta a discuss��o para novos estudos. A an��lise se elabora a partir da triangula����o, entre outros, do referencial te��rico com o processo de interven����o, produ����o de dados e no debate acad��mico em diferentes contextos. A partir da caminhada acad��mica permeada pela hist��ria e mem��ria, inferimos que as imagens escolares medeiam o processo formativo dos jovens do terceiro ano do Ensino M��dio no ensino da Arte. Contribuem para o cultivo da mem��ria escolar, enquanto presen��a impregnada pela hist��ria da institui����o, por meio da imag��tica dos seus ambientes intraescolares. Constatamos ainda que as imagens colaboram para o (re)conhecimento por parte desses sujeitos do seu papel ativo, aut��nomo e transformador da realidade escolar na qual est��o inseridos.

���Tamb��m queremos falar��� : representa����es socias dos alunos de ensino m��dio acerca da pol��tica de cotas da UFES

Este estudo buscou conhecer as representa����es sociais de alunos do ensino m��dio acerca da pol��tica afirmativa de cotas da UFES. Ao escolher realizar esta investiga����o cient��fica, optei trabalhar com a Teoria das Representa����es Sociais (TRS), justamente por se tratar de uma pesquisa de natureza qualitativa, permitindo compreender melhor esse conjunto de saberes sociais cotidianos, explica����es e afirma����es que se originam na vida di��ria desses alunos. Para coleta e an��lise dos dados elegi trabalhar com grupos focais e an��lise de conte��do, por acreditar que se tratam de t��cnicas mais apropriadas pelo tempo h��bil destinado a tal prop��sito e o car��ter explorat��rio dessa investiga����o. Foram eleitos como campo de pesquisa tr��s escolas que ofertam o ensino m��dio no munic��pio de Cachoeiro de Itapemirim. Sendo, respectivamente, uma da rede particular, uma estadual e uma federal. Apresentei tamb��m de forma introdut��ria os principais conceitos sistematizados por Serge Moscovici que serviram de coordenadas para a formula����o da TRS. Em um segundo momento, fa��o um debate dialogado sobre as rela����es raciais no Brasil atrav��s de autores que tentaram interpretar a realidade de um pa��s de passado escravista e patriarcal. Como resultado dos di��logos com alunos do ensino m��dio, percebi que as representa����es sociais desses estudantes est��o ancorados a um conjunto de palavras ligadas a ideia de igualdade, m��rito, preconceito pelas avessas, ���medida tapa buraco���. Entretanto, alunos favor��veis ��s pol��ticas de cotas utilizaram muito a palavra igualdade no sentido material da exist��ncia (econ��mico e social). Percebeu-se tamb��m diferen��as significativas n��o somente de institui����o para institui����o, como uma diversidade muito grande de concep����es dentro de uma mesma institui����o de ensino. Exemplo disso foi encontrado no IFES de Cachoeiro de Itapemirim, onde a vis��o sobre as cotas do primeiro grupo pertencente �� turma de inform��tica se aproximou mais das representa����es sociais dos alunos da escola particular, enquanto que as concep����es do segundo grupo do curso de eletromec��nica se conectavam mais com as falas dos alunos de escola p��blica.

Cantaloupe melon ( Cucumis melo L.) conservation using hydrocooling

ABSTRACT Maintaining cantaloupe melon at field temperature impairs conservation as it speeds up cell metabolism and transpiration, and, consequently, reduces shelf life. This study aimed to evaluate the conservation of Torreon hybrid cantaloupe using the hydrocooling treatment. Fruits were harvested at the commercial maturity stage (60 days after planting), in the morning, at the Nova California Farm, municipality of Mossoró-RN, in September 2007. One set of fruit was immersed in chilled water at 5 ��C for 5 min, at the packing house, while the remaining set was not hydro cooled. Then, both sets (treated and untreated with hydrocooling) were pre-cooled in air forced tunnels at 7 ��C, until the temperature in the pulp reached 10 ��C. Both fruit sets were stored for 0, 14, 21, 28 and 35 days under modified atmosphere at 3 �� 1 oC and 90 �� 5% RH. After each storage period, the fruits were incubated in an atmosphere-controlled chamber at 20 �� 2 oC and 80 �� 5% de RH, for seven days. The following characteristics were evaluated: external and internal appearance, mass loss, soluble solids, firmness and titrable acidity. The experiment was arranged in a completely randomized split-plot design with four replications of three fruits. The plots consisted of the hydrocooling conditions (with and without fruit soaking in chilled water), and the sub-plots consisted of the storage times (0, 14, 21, 28 and 35 days).The treatment with hydrocooling was efficient in keeping the firmness and soluble solids of the fruits and shortened the pre-cooling time in the cooling tunnel. However, hydrocooling did not increase fruit shelf-life.

On the moroccan tsunami catalogue

A primary tool for regional tsunami hazard assessment is a reliable historical and instrumental catalogue of events. Morocco by its geographical situation, with two marine sides, stretching along the Atlantic coast to the west and along the Mediterranean coast to the north, is the country of Western Africa most exposed to the risk of tsunamis. Previous information on tsunami events affecting Morocco are included in the Iberian and/or the Mediterranean lists of tsunami events, as it is the case of the European GITEC Tsunami Catalogue, but there is a need to organize this information in a dataset and to assess the likelihood of claimed historical tsunamis in Morocco. Due to the fact that Moroccan sources are scarce, this compilation rely on historical documentation from neighbouring countries (Portugal and Spain) and so the compatibility between the new tsunami catalogue presented here and those that correspond to the same source areas is also discussed.

Identity ��� towards a conceptualization

The development of economical relations increases the interaction between organizations and stakeholders. It is no more acceptable to manage an organization under a transactional perspective where suppliers had a fundamental role. Nowadays organizations are being managed under a relational perspective where relations and relationship management in general have consequences in identity management (Hakansson e Snehota, 1989, 1995). A correct perception and management of identity is necessary to achieve distinctiveness in the competitive environment. This way, identity is influenced by relations with stakeholders in general and particularly with competitors. The ICIG concept states that identity is related with the values of the organization and it helps creating distinctiveness in the competitive environment (Van Riel, Balmer, 1997); Baker and Balmer (1997) state that identity is what the organization is; Suvatjis and de Chernatony (2005) refer that expressing identity is a dynamic process that evolves the use of a management model to face context changes; Kapferer (1991) states that brand identity is the project, the self conception of the brand. After reviewing and confronting literature under the plethora of identities��� concepts and perspectives (He, Balmer, 2007) one can���t find an integrative answer with all the elements that contribute to identity of organizations. The authors are strongly interested to contribute to the elimination of this limitation and to answer to strategic management needs. In a marketing context one can find: - the corporate identity approach that is focused in the distinctive attributes of an organization (Abratt, Balmer, Marwick e Fill, Stuart, Balmer and Gray, Alessandri, Suvatjis and de Chernatony) - the brand identity approach (related with the application of corporate identity studies to brands) - Kapferer, Semprini, Aaker, de Chernatony). Kapferer (1991), one of the most prolific authors in this field was the first author to integrate identity in a brand concept. In his view, identity is an emission concept. This idea is shared also by Aaker (1996). Yet, identity has to be managed in a competitive environment which is constantly changing. After reviewing and confronting literature, authors select concepts that are generally accepted by the investigators in order to design a model to analyze and manage identity: - corporate identity models: personality, image/reputation, culture, philosophy, mission, strategy, structure, communication - some of these concepts derive from identity models and others from identity management models; - brand identity models ��� Kapferer (1991, 2008) identity prism, witch is basis of literature in this field: culture, physical facet, personality, relationship (between brand and consumer), reflected consumer, consumers` self-concept. After discussion authors decide to include other concept in line with other authors` view: country of origin (Aaker, 1996). A discussion eliminates the twin concepts and the final selection is as follows: personality, image/reputation, culture (including philosophy and mission), strategy, structure, communication, culture, physical facet, relationship (between brand and consumer), reflected consumer, consumers` self-concept and according to authors` reflections ���relationships��� deriving from competitors` actions in competitive environment. Competitors��� actions and decisions have a stronger influence in the organizations` positioning than any other stakeholder as stated before. This is a work in progress towards a new model in identity analysis and management so an exploratory study will follow inquiring experts on identity in order to evaluate these concepts and correct the theoretical perspectives.

Sistema de recomenda����o e personaliza����o de televis��o

Com a expans��o da Televis��o Digital e a converg��ncia entre os meios de difus��o convencionais e a televis��o sobre IP, o n��mero de canais dispon��veis tem aumentado de forma gradual colocando o espectador numa situa����o de dif��cil escolha quanto ao programa a visionar. Sobrecarregados com uma grande quantidade de programas e informa����o associada, muitos espectadores desistem sistematicamente de ver um programa e tendem a efectuar zapping entre diversos canais ou a assistir sempre aos mesmos programas ou canais. Diante deste problema de sobrecarga de informa����o, os sistemas de recomenda����o apresentam-se como uma solu����o. Nesta tese pretende estudar-se algumas das solu����es existentes dos sistemas de recomenda����o de televis��o e desenvolver uma aplica����o que permita a recomenda����o de um conjunto de programas que representem potencial interesse ao espectador. S��o abordados os principais conceitos da ��rea dos algoritmos de recomenda����o e apresentados alguns dos sistemas de recomenda����o de programas de televis��o desenvolvidos at�� �� data. Para realizar as recomenda����es foram desenvolvidos dois algoritmos baseados respectivamente em t��cnicas de filtragem colaborativa e de filtragem de conte��do. Estes algoritmos permitem atrav��s do c��lculo da similaridade entre itens ou utilizadores realizar a predi����o da classifica����o que um utilizador atribuiria a um determinado item (programa de televis��o, filme, etc.). Desta forma �� poss��vel avaliar o n��vel de potencial interesse que o utilizador ter�� em rela����o ao respectivo item. Os conjuntos de dados que descrevem as caracter��sticas dos programas (t��tulo, g��nero, actores, etc.) s��o armazenados de acordo com a norma TV-Anytime. Esta norma de descri����o de conte��do multim��dia apresenta a vantagem de ser especificamente vocacionada para conte��do audiovisual e est�� dispon��vel livremente. O conjunto de recomenda����es obtidas �� apresentado ao utilizador atrav��s da interac����o com uma aplica����o Web que permite a integra����o de todos os componentes do sistema. Para valida����o do trabalho foi considerado um dataset de teste designado de htrec2011-movielens-2k e cujo conte��do corresponde a um conjunto de filmes classificados por diversos utilizadores num ambiente real. Este conjunto de filmes possui, para al��m da classifica����es atribu��das pelos utilizadores, um conjunto de dados que descrevem o g��nero, directores, realizadores e pa��s de origem. Para valida����o final do trabalho foram realizados diversos testes dos quais o mais relevante correspondeu �� avalia����o da dist��ncia entre predi����es e valores reais e cujo objectivo �� classificar a capacidade dos algoritmos desenvolvidos preverem com precis��o as classifica����es que os utilizadores atribuiriam aos itens analisados.

Concurrent tabling

In the past few years Tabling has emerged as a powerful logic programming model. The integration of concurrent features into the implementation of Tabling systems is demanded by need to use recently developed tabling applications within distributed systems, where a process has to respond concurrently to several requests. The support for sharing of tables among the concurrent threads of a Tabling process is a desirable feature, to allow one of Tabling���s virtues, the re-use of computations by other threads and to allow efficient usage of available memory. However, the incremental completion of tables which are evaluated concurrently is not a trivial problem. In this dissertation we describe the integration of concurrency mechanisms, by the way of multi-threading, in a state of the art Tabling and Prolog system, XSB. We begin by reviewing the main concepts for a formal description of tabled computations, called SLG resolution and for the implementation of Tabling under the SLG-WAM, the abstract machine supported by XSB. We describe the different scheduling strategies provided by XSB and introduce some new properties of local scheduling, a scheduling strategy for SLG resolution. We proceed to describe our implementation work by describing the process of integrating multi-threading in a Prolog system supporting Tabling, without addressing the problem of shared tables. We describe the trade-offs and implementation decisions involved. We then describe an optimistic algorithm for the concurrent sharing of completed tables, Shared Completed Tables, which allows the sharing of tables without incurring in deadlocks, under local scheduling. This method relies on the execution properties of local scheduling and includes full support for negation. We provide a theoretical framework and discuss the implementation���s correctness and complexity. After that, we describe amethod for the sharing of tables among threads that allows parallelism in the computation of inter-dependent subgoals, which we name Concurrent Completion. We informally argue for the correctness of Concurrent Completion. We give detailed performance measurements of the multi-threaded XSB systems over a variety of machines and operating systems, for both the Shared Completed Tables and the Concurrent Completion implementations. We focus our measurements inthe overhead over the sequential engine and the scalability of the system. We finish with a comparison of XSB with other multi-threaded Prolog systems and we compare our approach to concurrent tabling with parallel and distributed methods for the evaluation of tabling. Finally, we identify future research directions.
