Calibration of consumer knowledge of the web

Calibration of consumer knowledge of the web refers to the correspondence between accuracy and confidence in knowledge of the web. Being well-calibrated means that a person is realistic in his or her assessment of the level of knowledge that he or she possesses. This study finds that involvement leads to better calibration and that calibration is higher for procedural knowledge and common knowledge, as compared to declarative knowledge and specialized knowledge. Neither usage, nor experience, has any effect on calibration of knowledge of the web. No difference in calibration is observed between genders. But, in agreement with previous findings, this study also finds that males are more confident in their knowledge of the web. The results point out that calibration could be more a function of knowledge-specific factors and less that of individual-specific factors. The study also identifies flow and frustration with the web as consequences of calibration of knowledge of the web and draws the attention of future researchers to examine these aspects.

Are we on the same page? Knowledge boundaries and transactive memory system development in cross-functional teams

One of the key challenges that organizations face when trying to integrate knowledge across different functions is the need to overcome knowledge boundaries between team members. In cross-functional teams, these boundaries, associated with different knowledge backgrounds of people from various disciplines, create communication problems, necessitating team members to engage in complex cognitive processes when integrating knowledge toward a joint outcome. This research investigates the impact of syntactic, semantic, and pragmatic knowledge boundaries on a team’s ability to develop a transactive memory system (TMS)—a collective memory system for knowledge coordination in groups. Results from our survey show that syntactic and pragmatic knowledge boundaries negatively affect TMS development. These findings extend TMS theory beyond the information-processing view, which treats knowledge as an object that can be stored and retrieved, to the interpretive and practice-based views of knowledge, which recognize that knowledge (in particular specialized knowledge) is localized, situated, and embedded in practice.

Understanding consumer loyalty to technology-based self-services with credence qualities

Purpose This paper aims to use the Model of Goal-Directed Behavior (MGB) to examine the factors affecting consumers’ continued use of emerging technology-based self-services (TBSSs) with credence qualities. Professional services, which traditionally require specialized knowledge and high levels of interpersonal interaction to produce owing to their credence qualities, are increasingly delivered via self-service technologies. Health services delivered via mobile devices, for example, facilitate self-care without direct involvement from health professionals. Design/methodology/approach A mental health service delivered via the Internet and mobile phone, myCompass, was selected as the research context. Twenty interviews were conducted with users of myCompass and the data were thematically analyzed. Findings The findings of the study showcase the unique determinants of consumers’ continued use of TBSSs with credence qualities relative to the more routine services which have been the focus of extant research. The findings further provide support for the utility of the MGB in explaining service continuance, although the importance of distinguishing between extrinsic and intrinsic motivational components of behavioral desire and capturing the impact of social influence beyond subjective norms is also highlighted. Originality/value This study contributes to recent research examining differences in consumer responses across TBSSs and behavioral loyalty to these services. It also provides empirical evidence for broadening and deepening the MGB within this behavioral domain.

Using conceptual tool for intuitive interaction to design intuitive website for SME in India : A case study

Statistical reports of SMEs Internet usage from various countries indicate a steady growth. However, deeper investigation of SME’s e-commerce adoption and usage reveals that a number of SMEs fail to realize the full potential of e-commerce. Factors such as lack of tools and models in Information Systems and Information Technology for SMEs, and lack of technical expertise and specialized knowledge within and outside the SME have the most effect. This study aims to address the two important factors in two steps. First, introduce the conceptual tool for intuitive interaction. Second, explain the implementation process of the conceptual tool with the help of a case study. The subject chosen for the case study is a real estate SME from India. The design and development process of the website for the real estate SME was captured in this case study and the duration of the study was four months. Results indicated specific benefits for web designers and SME business owners. Results also indicated that the conceptual tool is easy to use without the need for technical expertise and specialized knowledge.

Laboratory analyses for evaluation of platelet disorders and platelet concentrates

High quality of platelet analytics requires specialized knowledge and skills. It was applied to analyze platelet activation and aggregation responses in a prospective controlled study of patients with Finnish type of amyloidosis. The 20 patients with AGel amyloidosis displayed a delayed and more profound platelet shape change than healthy siblings and healthy volunteers, which may be related to altered fragmentation of mutated gelsolin during platelet activation. Alterations in platelet shape change have not been reported in association with platelet disorders. In the rare Bernard-Soulier syndrome with Asn45Ser mutation of glycoprotein (GP) IX, the diagnostic defect in the expression of GPIb-IX-V complex was characterized in seven Finnish patients, also an internationally exceptionally large patient series. When measuring thrombopoietin in serial samples of amniotic fluid and cord blood of 15 pregnant women with confirmed or suspected fetal alloimmune thrombocytopenia, the lower limit of detection could be extended. The results approved that thrombopoietin is present already in amniotic fluid. The application of various non-invasive means for diagnosing thrombocytopenia (TP) revealed that techniques for estimating the proportion of young, i.e. large platelets, such as direct measurement of reticulated platelets and the mean platelet size, would be useful for evaluating platelet kinetics in a given patient. Due to different kinetics between thrombopoietin and increase of young platelets in circulation, these measurements may have most predictive value when measured from simultaneous samples. Platelet autoantibodies were present not only in isolated autoimmune TP but also in patients without TP where disappearance of platelets might be compensated by increased production. The autoantibodies may also persist after TP has been cured. Simultaneous demonstration of increased young platelets (or increased mean platelet volume) in peripheral blood and the presence of platelet associated IgG specificities to major glycoproteins (GPIb-IX and GPIIb-IIIa) may be considered diagnostic for autoimmune TP. Measurement of a soluble marker as a sign of thrombin activation and proceeding deterioration of platelet components was applied to analyze the alterations under several stress factors (storage, transportation and lack of continuous shaking under controlled conditions) of platelet products. The GPV measured as a soluble factor in platelet storage medium showed good correlation with an array of other measurements commonly applied in characterization of stored platelets. The benefits of measuring soluble analyte in a quantitative assay were evident.

Sociedade Contemporânea e Cuidados Paliativos: a morte e o morrer no campo da saúde

Este trabalho refere-se a uma pesquisa qualitativa exploratória que tem por objetivo geral investigar alguns aspectos que marcam a experiência da morte na modernidade, como sua crescente desqualificação e ocultamento social, e mais recentemente, no período denominado de contemporâneo, a sua maior visibilidade no campo dos saberes especializados, a fim de avaliar como tais questões se materializam no campo da assistência em saúde. Essa discussão servirá de base para a reflexão sobre o novo modelo de assistência denominado de cuidados paliativos, o qual tem significado uma tentativa de humanizar o cuidado dispensado a pacientes portadores de doença avançada, sem possibilidades de cura ou em fase de terminalidade da vida.Para tal, parte-se de uma análise da panorâmica histórica sobre os modos como a questão da morte se apresenta no século XX, além do processo de emergência do novo modelo assistencial, sendo abordados os conceitos de morte moderna - que reflete uma objetivação da morte pelo conhecimento técnico científico no campo da medicina - e morte contemporânea ou neomoderna - surgida como reação a esta última, caracterizada principalmente pela reivindicação ao direito de morrer com dignidade. Para cumprir os objetivos específicos, quais sejam, conhecer um serviço de cuidados paliativos no cotidiano de um hospital, mapear suas principais características e coletar dados sobre a dinâmica e organização do serviço foi realizada uma breve observação através de visitas ao Programa de Tratamento da Dor e Cuidados Paliativos do Hospital Universitário Clementino Fraga Filho da Universidade Federal do Rio de Janeiro (HUCFF/UFRJ). Os resultados mostraram que nos últimos 40 anos houve uma mudança notável das atitudes e das representações associadas ao fim da vida.Isso promoveu o surgimento de novas filosofias e formas alternativas para lidar com a morte e o morrer, de que os cuidados paliativos são o representante maior neste início de século, tornando-se hegemônicos no cuidado ao fim da vida nos domínios profissionais, associativos e políticos. Mostraram que os cuidados paliativos têm sido integrados ao sistema público de saúde em nosso país a partir das políticas nacionais voltadas para a realidade do câncer, com desenvolvimento especialmente no contexto hospitalar de alta complexidade, ainda circunscritos exclusivamente ao domínio do especialista, fato indicado pelo desconhecimento da clientela sobre a existência e natureza do serviço.

Tia, existe flor preta?: educar para as relações étnico-raciais

A pesquisa que se insere na linha Infância, Juventude e Educação do Programa de Pós-Graduação em Educação, da Universidade do Estado do Rio de Janeiro/UERJ, teve por objetivo compreender as enunciações que professoras e estudantes de Pedagogia produziram nas discussões do Ciclo de Palestras Direitos Humanos e Educação Infantil: questões de raça, etnia, sexo e gênero, realizado na UERJ, durante cinco encontros quinzenais, sobre a questão raça e etnia, em 2013. O procedimento metodológico do Ciclo foi de palestras expositivas, sessões reflexivas que produziram amplo debate crítico com os 40 participantes. O material empírico analisado na dissertação foi composto pelas enunciações produzidas pelos participantes relativas às questões étnico-raciais: relatos de preconceito, discriminação e racismo. A pesquisa adotou uma abordagem qualitativa e procurou compreender as enunciações a partir do aporte teórico proposto por Bakhtin. Esta abordagem teórica dialogou com outras que subsidiaram o ciclo de palestras e as presentes no levantamento bibliográfico realizado (2003 2013), que visou observar a materialidade da Lei 10.639/13 e das DCNERER. A partir do corpus de enunciações da pesquisa elegemos três eixos temáticos: (1) As relações étnico-raciais no Brasil; (2) Práticas racistas e antirracistas na Educação Infantil e (3) A formação de professores para a educação das relações étnico-raciais. As análises apontaram que as atividades de problematização e discussão sobre o tema são importantes e necessárias, diante à lacuna de formação e conhecimentos especializados, em contraponto às dificuldades cotidianas e embaraços voltados às questões de raça e etnia vividas por professores e crianças negras ou não, no cotidiano das Instituições de Educação Infantil. Os participantes reconheceram o próprio despreparo para atuar frente às questões em estudo e propuseram estratégias de ação nas suas práticas pedagógicas com as crianças

RABBIT: A Compiler for SCHEME

We have developed a compiler for the lexically-scoped dialect of LISP known as SCHEME. The compiler knows relatively little about specific data manipulation primitives such as arithmetic operators, but concentrates on general issues of environment and control. Rather than having specialized knowledge about a large variety of control and environment constructs, the compiler handles only a small basis set which reflects the semantics of lambda-calculus. All of the traditional imperative constructs, such as sequencing, assignment, looping, GOTO, as well as many standard LISP constructs such as AND, OR, and COND, are expressed in macros in terms of the applicative basis set. A small number of optimization techniques, coupled with the treatment of function calls as GOTO statements, serve to produce code as good as that produced by more traditional compilers. The macro approach enables speedy implementation of new constructs as desired without sacrificing efficiency in the generated code. A fair amount of analysis is devoted to determining whether environments may be stack-allocated or must be heap-allocated. Heap-allocated environments are necessary in general because SCHEME (unlike Algol 60 and Algol 68, for example) allows procedures with free lexically scoped variables to be returned as the values of other procedures; the Algol stack-allocation environment strategy does not suffice. The methods used here indicate that a heap-allocating generalization of the "display" technique leads to an efficient implementation of such "upward funargs". Moreover, compile-time optimization and analysis can eliminate many "funargs" entirely, and so far fewer environment structures need be allocated at run time than might be expected. A subset of SCHEME (rather than triples, for example) serves as the representation intermediate between the optimized SCHEME code and the final output code; code is expressed in this subset in the so-called continuation-passing style. As a subset of SCHEME, it enjoys the same theoretical properties; one could even apply the same optimizer used on the input code to the intermediate code. However, the subset is so chosen that all temporary quantities are made manifest as variables, and no control stack is needed to evaluate it. As a result, this apparently applicative representation admits an imperative interpretation which permits easy transcription to final imperative machine code. These qualities suggest that an applicative language like SCHEME is a better candidate for an UNCOL than the more imperative candidates proposed to date.

Creche: de lugar de abandono a espaço educativo

Esta dissertação apresenta um estudo histórico da creche no Brasil, tendo por objetivo analisar como a mesma instituição que carrega o estigma de lugar de abandono é compreendida atualmente por alguns segmentos sociais como espaço educativo. A questão da creche particular é privilegiada. A partir de uma abordagem que reconhece a importância da influência do contexto sócio-econômico nas propostas educativas, inicialmente foi feito um acompanhamento da trajetória histórica da creche no Brasil, analisando à luz de alguns estudos sobre a problemática da mulher, as relações entre a demanda por creches e a situação feminina no que diz respeito ao trabalho e à família. Em seguida destacaram-se as relações entre os ob jetivos que historicamente foram sendo definidos para as instituições destinadas à criança pequena, e o desenvolvimento dos conhecimentos sobre esta criança, privilegiando-se o estudo do movimento da Escola Nova. Posteriormente, realizou-se a análise das primeiras revistas que desde a déca da de 70 popularizam estes conhecimentos e que vêm criando determinada visão de creche. Finalmente, a entrada da classe média como clientela desta instituição, que vai dar enfase ao seu aspecto educativo, é compreendida a partir do processo de modernização da sociedade, com o aumento da presença da mulher no mercado de trabalho, e a difusão do conhecimento sobre a criança pequena.

SAMVC sistema de autoria de museus virtuais colaborativos

The use of graphical objects three-dimensional (3D) multimedia applications is gaining more space in the media. Networks with high transmission rates, computers with large processing and graphics boost and popularize such three-dimensional applications. The areas of 3D applications ranging from military applications, entertainment applications geared up for education. Within the applications related to education, we highlight the applications that create virtual copies of cultural spaces such as museums. Through this copy, you can virtually visit a museum, see other users, communicate, exchange information on works, etc. Thereby allowing the visit museums physically distant remote users. A major problem of such virtual environments is its update. By dealing with various media (text, images, sounds, and 3D models), its subsequent handling and update on a virtual environment requires staff with specialized knowledge. Speaking of museums, they hardly have people on your team with this profile. Inside the GT-MV (Grupo de Trabalho de Museus Virtuais), funded by RNP (Rede Nacional de Ensino e Pesquisa) propose a portal for registration, amendment and seen collaborative virtual museums of Brazil. The update, be it related to work or physical space, a system with a national scale like this, would be impossible if done only by the project team. Within this scenario, we propose the modeling and implementation of a tool that allows editing of virtual spaces in an easy and intuitive as compared with available tools. Within the context of GT-MV, we apply the SAMVC (Sistema de Autoria de Museus Virtuais Colaborativos) to museums where curators build the museum from a 3D floor plan (2D). The system, from these twodimensional information, recreates the equivalent in three dimensions. With this, through little or no training, team members from each museum may be responsible for updating the system

Nervos: rede de discursos e práticas de cuidado na atenção básica no município de Natal/RN

The Primary Health Care and one of its main strategies, the Family Health Strategy (ESF), are framed as the gateway to the Public Health System (SUS). Thus, most of the incident and prevalent health problems in the population attended should be solved at this level of care, including psychological suffering, and the so-called complaint of nerves. Nerves and nervous denote a complexity that is not always well comprehended by health workers, in such a way that the care to this kind of problem is usually inadequate. In this line of thought, the general objective of this study is to analyze the network of discourses and the care to the psychological suffering, expressed as nerves, in SUS daily Primary Health Care. Besides and more specifically, it aims at identifying the principles and guidelines of the Primary Health Care in mental health; to investigate health workers positioning before psychological suffering and complaints of nerves, and also analyze different actions and practices of care carried out in different Health Units towards complaints like nerves. Institutional Ethnography was the theoreticalmethodological perspective adopted for the work. This approach seeks to understand and analyze the institutional relationships in a particular context considering sociostructural influences and power relations, as well as daily discourses and practices. Based on interviews with health professionals, informal conversations and observations in six Health Units with ESF teams from different sanitary districts in Natal/RN, it was possible to check that the index of complaint of nerves is high. The referral to psychologists and psychiatrists, as well as the prescription of psychotropic drugs appear as the most common intervention at this level of care. In general, the participants complain that they have poor specialized knowledge about the theme of mental health. They face the problem of bad work conditions and the lack of institutional support, which make actions of illnesses prevention and health promotion even more difficult. Besides, there are different ongoing practices such as meetings for hypertensive and aged people, walk, visit, round-table discussions and community therapy. However, not all of these actions are aimed at the care of psychological suffering. It is observed that the Matrix Support, which is a methodological strategy of supervision and follow up forcases of mental health, hasn t been totally implemented in the municipal system, although it is a tool that has been used by psychologists in some Health Units in the city. It was also verified that the health care practices to the problem of nerves strongly depend on the professional s commitment with the PSF guidelines and on mental health policies, in addition to continued support, when available, from other professional who works as matrix supporter

Vidas presas: uma tentativa de compreensão da tragédia da criminalidade junto às suas personagens prisioneiras

Cet article présente une recherche sur les facteurs producteurs de la criminalité réalisée au début de la décennie 80 qui, en s'appuyant sur longs entretiens réalisées avec des prisonnières, a élaboré un ensemble d'hypothèses afin de comprendre les relations constitutives que ce phénomène maintient avec la pauvreté, avec la violence policière/pénitentiaire et avec les propres savoirs par lesquels ses actes et ses auteurs deviennent objet de connaissance. Sa présentation, aujourd'hui, vise deux objectifs: le premier, en hommage et reconnaissance à Sylvia Leser de Mello, est celui d'offrir un simple exemple, parmi tant d'autres, d'une des nombreuses aventures de recherche rendue possible par son orientation. Le second est celui de partager avec des chercheurs qui s'intéressent au même thème une étude qui, polémique et innovatrice à l'époque de sa réalisation, conserve sa pertinence face, actuellement, aux caractéristiques particulièrement graves présentées par les questions abordées.

Short-term planning of electric power distribution networks using multiobjective genetic algorithim

The high active and reactive power level demanded by the distribution systems, the growth of consuming centers, and the long lines of the distribution systems result in voltage variations in the busses compromising the quality of energy supplied. To ensure the energy quality supplied in the distribution system short-term planning, some devices and actions are used to implement an effective control of voltage, reactive power, and power factor of the network. Among these devices and actions are the voltage regulators (VRs) and capacitor banks (CBs), as well as exchanging the conductors sizes of distribution lines. This paper presents a methodology based on the Non-Dominated Sorting Genetic Algorithm (NSGA-II) for optimized allocation of VRs, CBs, and exchange of conductors in radial distribution systems. The Multiobjective Genetic Algorithm (MGA) is aided by an inference process developed using fuzzy logic, which applies specialized knowledge to achieve the reduction of the search space for the allocation of CBs and VRs.
