Globalização de competências tecnológicas inovadoras no contexto de industrialização recente: evidências de uma amostra de institutos de pesquisa e desenvolvimento (P&D) em Tecnologias de Informação e Comunicação (TIC) no Brasil

This dissertation adds new evidences and explanations to two distinct streams of debate. The first one refers to the globalisation (or dissemination) of technological innovative capabilities in the context of newly industrialised economies. The second one refers to common generalisations about the deterioration of the innovative capabilities in Latin American countries after 1990. This study was motivated by a lack of empirical studies focused on the relationship between the globalisation of innovative capabilities and sources to build them up in emerging organisations, especially R&D institutes. This dissertation is focused on the globalisation of innovative capabilities at the information and communication technology industry in Brazil. The globalisation of innovative capabilities is measured by the technological capabilities types and levels of 18 national R&D institutes related to this industry. Besides, this dissertation examines sources to build up innovative capabilities in the sampled institutes, namely: their intra-organisational learning processes and the linkages established with firms and the technological infra-structure. The study is based on first-hand empirical evidences, collected by different data-gathering sources in an extensive fieldwork. The data were examined with analytical frameworks, organised in the light of the theoretical basis of the study. The study has found the dissemination of innovative capabilities has been occurring in the Brazilian ICT industry with the involvement of the technological infra-structure with innovative activities. Besides that, the variety of the intra-organisational learning processes and the types of linkages established with technological infra-structure and firms have been influencing the development of innovative capabilities. The evidences that emerge from this study contradict common generalizations and arguments about the inexistence of innovative activities and about the technological infra-structure weakness in emerging or newly industrialized economies.

O papel da confiança na coprodução

Esse trabalho investigou empiricamente a influência que a confiança que o cliente deposita no prestador de serviços exerce sobre a efetividade da coprodução do cliente em serviços intensivos em conhecimento baseados em tecnologia. Para tanto, foi realizada uma revisão da literatura de marketing de serviços e de gerenciamento de operações sobre a participação do cliente na produção e entrega de serviços, que é o que caracteriza genericamente a coprodução do cliente. Também foi revisada a literatura sobre serviços intensivos em conhecimento, em busca de entender suas características e especificidades, e sobre confiança, especialmente na área de marketing de relacionamento. Sobre a participação do cliente na produção e entrega de serviços, constatou-se que existe na literatura uma visão consagrada que trata o cliente como “funcionário parcial” da empresa durante os encontros de serviços. Essa visão propõe recorrentemente um modelo conceitual em que a efetividade da coprodução do cliente apresenta três antecedentes fundamentais: clareza de papel, motivação e expertise do cliente. Além disso, foi identificada uma proposição teórica especificamente para o setor de serviços intensivos em conhecimento, nunca testada empiricamente, que sugere que esses três antecedentes da efetividade da coprodução são influenciados por um conjunto de comportamentos colaborativos desejáveis, batizados de responsabilidades do papel do cliente. Dessa forma, este trabalho testou um modelo conceitual que estabeleceu a confiança e as responsabilidades do papel do cliente como antecedentes da clareza de papel, motivação e expertise do cliente no processo de coprodução do cliente. Foi utilizada uma abordagem quantitativa e os dados foram levantados junto a profissionais que já participaram de projetos de software na condição de clientes. A coleta de dados usou um questionário estruturado construído a partir de escalas de mensuração de estudos anteriores. As relações entre os conceitos foram testadas por meio da técnica de modelagem de equações estruturais. Os resultados obtidos apresentaram evidências de que a confiança e as responsabilidades do papel do cliente impactam positivamente a clareza de papel, a motivação ou a expertise do cliente, abrindo espaço para pesquisas futuras que aprofundem o entendimento das relações entre esses conceitos e sua importância para a efetividade da coprodução do cliente.

Segurança e gestão de riscos na atividade pericial

Os riscos fazem parte da vida das pessoas quaisquer que sejam suas profissões ou atividades. No caso dos policiais estes riscos são ampliados devido às situações as quais estão sujeitos e em particular no caso dos peritos criminais federais, que além dos relacionados às suas atividades policiais tem outras que são inerentes à perícia. Esta dissertação teve como objetivo identificar os principais riscos de segurança no ambiente de trabalho dos peritos criminais da Polícia Federal. A pesquisa, sob seu ponto de vista metodológico foi classificada quanto à sua natureza como aplicada; no tocante à abordagem do problema se classifica como qualitativa e quanto aos seus objetivos trata-se de pesquisa descritiva. A respeito dos procedimentos técnicos a pesquisa foi classificada como bibliográfica, pesquisa de levantamento e estudo de caso com aplicação na perícia criminal federal. Para tanto foram utilizados instrumentos de coleta de dados online os quais foram disponibilizados para peritos criminais de todas as áreas e unidades de federação. Os dados demonstraram que apesar de existirem diversos riscos relacionados com a atividade-fim pericial há outros com potencial para se transformarem em acidentes, principalmente os relacionados com questões policiais como abordagens, missões e operações. Os riscos foram mapeados por áreas da perícia utilizando-se como base a NR-5 que trata dos mapas de riscos. Com a pesquisa provocou-se a discussão a respeito dos riscos a que estão sujeitos os peritos e com isso criou-se uma conscientização da necessidade de tratamento dos mesmos. Com a participação dos peritos de todas as áreas de formação e unidades da federação, conseguiu-se numa perspectiva qualitativa identificar os principais riscos por grupos (físicos, químicos, biológicos, ergonômicos e de acidentes). Conclui-se que se faz necessário, em caráter de urgência, maior aprofundamento e discussões a respeitos dos riscos, bem como a criação de procedimentos mínimos a serem adotados para que os mesmos não se concretizem. A visão necessária para tratar estes riscos não pode ficar restrita a área pericial, mas precisa ser estendida para toda a Polícia Federal, e precisa ser inserida na filosofia, práticas e processos que permitam criar uma verdadeira cultura de gestão estratégica de riscos.

Food waste in lower-middle income households: a qualitative analysis of antecedents and a typology of food wasters

Esta dissertação doutoral, com base em dados empíricos coletados com 50 mães distribuídas no Brasil (n = 30) e nos EUA (n = 20), tem como objetivo fornecer uma melhor compreensão do desperdício de alimento no contexto da baixa renda. A tese é composta por três artigos, que combinados, cumprem os objetivos de identificar os antecedentes do desperdício de alimento e delinear uma tipologia dos desperdiçadores de alimento. Adicionalmente, contextualiza o desperdício global e um capítulo propõe uma agenda futura para estudos sobre desperdício de alimento no âmbito do consumidor. O desperdício de alimento nas famílias, enquanto tema de pesquisa, oferece a oportunidade para o trabalho acadêmico em marketing cumprir os critérios de relevância social, gerencial e para políticas públicas. No primeiro estudo, descrevem-se os fatores do chamado "paradoxo do desperdício de alimento", a identificação e análise do desperdício de alimento em famílias com restrições orçamentárias, enquanto apresentam-se o itinerário do consumo de alimentos e os antecedentes do desperdício. Este primeiro artigo, elaborado com dados coletados em famílias brasileiras, ilustra também o papel das normas culturais, tais como o preparo abundante de alimento para mostrar hospitalidade ou como forma de não ser percebido como pobre, no aumento do desperdício. No segundo artigo, uma grounded-theory (teoria fundamentada nos dados) destaca o papel do afeto e da abundância no desperdício de alimento familiar. Para enriquecer as contribuições teóricas, este segundo estudo apresenta um framework com seis dimensões do desperdício de alimento (1. Afeto; 2. Abundância; 3. Multiplicidade de escolhas; 4. Conveniência; 5. Procrastinação; 6. Rotina sem planejamento). Baseado em dados empíricos coletados em famílias americanas, este estudo proporciona novas explicações, a exemplo de como o estoque abundante de comfort foods - uma forma de impulsionar tanto emoções positivas para si quanto mostrar afeto para crianças – pode gerar mais desperdício de alimentos. Em síntese, o segundo artigo identifica uma consequência negativa do afeto e da abundância de alimentos no contexto familiar, e apresenta um framework teoricamente relevante. Finalmente, o terceiro artigo, a partir do conjunto de dados dos estudos anteriores e de nova coleta com dez famílias, propõe uma tipologia comportamental do desperdício de alimento, uma contribuição original aos estudos de comportamento do consumidor. A identificação de cinco tipos de desperdiçadores de alimentos - (1) Mães carinhosas; (2) Cozinheiras abundantes; (3) Desperdiçadoras de sobras; (4) Procrastinadoras; (5) Mães versáteis - contribui para a teoria, enquanto implicações potenciais para educadores nutricionais e agentes públicos são exploradas a partir dos resultados. Como uma forma de explicar as características de cada um dos cinco tipos identificados, compara-se aspectos das amostras brasileira e norte-americana, que apresentam similaridades no comportamento de desperdício de alimento. Os níveis de desperdício percebidos por país também são comparados. Em suma, os achados dos três artigos podem contribuir para maximizar os resultados de campanhas de conscientização voltadas à mitigação do desperdício de alimento, e apresentam ideias para varejistas interessados em iniciativas de sustentabilidade. Mais abrangentemente, os resultados apresentados também podem ser aplicados para incrementar programas de combate à fome e projetos de educação nutricional realizados pelo setor público ou ONGs.

Entre o mar e estrela, um lugar para se bem viver : a problemática da expansão urbana da Cidade de Baía Formosa/RN

The urban expansion problem of Baía Formosa, a southern edge city of de Rio Grande do Norte eastern coast, which has been presented in other coast Brazilian towns, specially on those with tourist activities increase. Therefore, this situation brings huge concerns to their inhabitants, to their technical /scientific community and to the governments, because of the conflicts of interest and of the growth of urban problems that this has been created. At Baía Formosa, the situation is aggravated because the city is confined, once around it, there are large private proprieties, environmental preservation area and the sea, at the eastern edge. The objectives of this study are the analyses of this city expansion process in order to obtain adequate alternatives and defining methodology to apply in other urban nucleus that are subjected to similar situations. Of course, presents social relations, environmental conditions and promoting local population insertion should be considered in order that enjoin this process and contributing to a better social balance. This case study has used bibliography research, field data, maps and soil occupation recorders and photographs of the area, besides the primary data gathering by surveys carried out with many social actors. The present analysis shows that the urban expansion observed today is featured by a recent unsustainable model, which attacks the environment and brings either farm conflicts. On the other hand, the ecological tourism can represent an alternative in order to achieve an adequate expansion form, without forgetting the several structural parameters necessary to support the sustainable activities

Relações entre teorias da história e ensino de história: a compreensão de professores

This thesis has as an objective to think over the teachers` understanding of the school History of the Fundamental Teaching regarding the existent relations between the history theories and the teaching of the school History, as well as to think over how these teachers see the influence that their teaching practice gets from the history theories. The work is based on the postulates of the qualitative research and on the characteristics of the ethnography of the school practice. The main procedures of data gathering were the documental analysis, the semi-structured interviews, the field diary and the observations of classes. The scientific perspective of the multiple references is an important source in this research. The participants of this work are two teachers of the school district of Natal who work in the field of the school History in two schools on the North Side of the city. The accomplished analysis point to significant indications that didn't occur continuous and regular teaching situations in the initial and continuing education of these teachers that clearly showed the relations between the history theories and the teaching of the school History. They also suggest that their understanding about the influence that their teaching practice gets from the history theories, is not still explicit. We understand that the relations between the history theories and the teaching of the school History are important for the initial and continuing education of these teachers who belong in this knowledge field, even when these relations are not explicitly pointed by the teachers, because they will always influence the teaching practice that the teachers of the school History build

Campo educacional e representação social da formação docente :o olhar dos agentes

Teaching formation has been the target of many changes, having been forged according to numerous formats and models through different times and spaces, composing thus, different codes and curricular proposals for different levels of qualification. We've tried in this work to pinpoint the main discussions which take place in the area of the teaching formation, based in the views of modern writers. We ve also tried, through the Social Representations Theory, to reveal and learn how the agents directly involved in this process realize and react, that is, the teachers who cope with the beginning stages of the Fundamental Teaching in the public school system in Natal/RN, taking into account that, in many cases, such formation demands the rethinking of the very formation policies. We've also adopted the concepts of field and educational field introduced by the praxiology of Pierre Bourdieu. It s been considered a fundamental theoretical reference which enables the understanding of social phenomena, both in macro and micro viewpoints. Thus, we do not neglect the whole, and particularly, the nuances of each context or specific situation. In the methodological track we ve used for data gathering the Free Word Association Test, and the Semi-Structured Interview, and also secondary sources for the characterization of the research spectre. Data treatment and analysis were performed with the help of the following software: SPSS Statistical Package for Social Sciences and EVOC; and the method of Content Category Analysis. The combination of the concepts and techniques mentioned above was necessary to cope with the qualitative and quantitative aspects, in our attempt to offer a wider range of contributions and outcome validations, which have shown, among other less explicit elements, the existence of a social representation of the teaching formation such as: knowledge theoretical and practical; a necessity imposed by the symbolical conflicts of the social field; capacitation and compromisse. We acknowledge the relevance of the thoughts discussed here, though aware that this is just one of the possible approaches to the theme

Modelos de sobrevivência com fração de cura e omissão nas covariáveis

In this work we study the survival cure rate model proposed by Yakovlev (1993) that are considered in a competing risk setting. Covariates are introduced for modeling the cure rate and we allow some covariates to have missing values. We consider only the cases by which the missing covariates are categorical and implement the EM algorithm via the method of weights for maximum likelihood estimation. We present a Monte Carlo simulation experiment to compare the properties of the estimators based on this method with those estimators under the complete case scenario. We also evaluate, in this experiment, the impact in the parameter estimates when we increase the proportion of immune and censored individuals among the not immune one. We demonstrate the proposed methodology with a real data set involving the time until the graduation for the undergraduate course of Statistics of the Universidade Federal do Rio Grande do Norte

Contato corporal entre adolescentes através da dança de salão na escola

The objective of this study was to identify the reaction and perception of adolescents in relation to body contact as well as emotional expressions through ballroom dancing. Forty-two adolescents from a public elementary school in the state of São Paulo participated in the study. Data gathering was conducted in groups by filming the ballroom dance class and applying a questionnaire about the experience. The dance experience was observed to provide greater body proximity and demonstration of affection, since part of the participants reported well-being, while others reported being embarrassed by dancing with a partner from the opposite sex. It was concluded that more dance activities related to biopsychosocial development need to be offered at school since ballroom dancing can help in interaction promoting body contact and thus facilitate in the process of interpersonal relations between adolescents.

Construct validity of a figure rating scale for Brazilian adolescents

Background: Figure rating scales were developed as a tool to determine body dissatisfaction in women, men, and children. However, it lacks in the literature the validation of the scale for body silhouettes previously adapted. We aimed to obtain evidence for construct validity of a figure rating scale for Brazilian adolescents.Methods: The study was carried out with adolescent students attending three public schools in an urban region of the municipality of Florianopolis in the State of Santa Catarina (SC). The sample comprised 232 10-19-year-old students, 106 of whom are boys and 126 girls, from the 5th series (i.e. year) of Primary School to the 3rd year of Secondary School. Data-gathering involved the application of an instrument containing 8 body figure drawings representing a range of children's and adolescents' body shapes, ranging from very slim (contour 1) to obese (contour 8). Weights and heights were also collected, and body mass index (BMI) was calculated later. BMI was analyzed as a continuous variable, using z-scores, and as a dichotomous categorical variable, representing a diagnosis of nutritional status (normal and overweight including obesity).Results: Results showed that both males and females with larger BMI z-scores chose larger body contours. Girls with higher BMI z-scores also show higher values of body image dissatisfaction.Conclusion: We provided the first evidence of validity for a figure rating scale for Brazilian adolescents.

Terapia de linguagem no espectro autístico: a interferência do ambiente terapêutico

OBJETIVO: Analisar o perfil funcional da comunicação de crianças e adolescentes com distúrbios do espectro autístico em dois ambientes de terapia de linguagem, que se diferenciam quanto ao aspecto físico. MÉTODOS: Participaram dez sujeitos com distúrbios do espectro autístico, seis do gênero masculino e quatro do gênero feminino, com idades entre 4 e 13 anos. Na coleta de dados, foram realizadas filmagens de oito sessões de terapia de linguagem individual com duração de 30 minutos, sendo quatro sessões em uma sala comum e quatro em uma sala com ambientação específica (sala NIC), intercaladamente, durante um mês. Para a análise dos dados foi empregado o Protocolo de Pragmática, e os resultados receberam tratamento estatístico. RESULTADOS: Verificou-se que não houve diferença significativa entre o perfil pragmático apresentado pelos dez sujeitos na sala comum e na sala NIC. CONCLUSÃO: O contexto físico aqui estudado não influenciou significativamente no perfil funcional da comunicação de indivíduos do espectro autístico, ainda que se tenha verificado tendências individuais apresentando melhor desempenho em uma sala ou em outra.

Ecologia humana e manejo participativo da pesca do búzio Anomalocardia brasiliana (Gmelin, 1791) (Bivalvia: Veneridae) na Reserva de Desenvolvimento Sustentável Estadual Ponta do Tubarão (RN)

Coastal and marine protected areas are created to protect habitat, avoid biodiversity loss, and to help maintain viable fisheries. However, most of these areas in tropical countries occurs in impoverished regions and directly affect the livelihood and survival of coastal communities which directly depend on fisheries and shellfisheries. Therefore, socioeconomic and conservation goals overlap. In this context, fishers should have a central place in resource management. They are critical resource users and their behavior directly affects the system. Shellfish resources are important sources of food, employment and income to fishing communities in Latin America. But despite its widespread use for food and income, there is an urgent need of more research on shellfish management. This research discusses the artisanal fisheries of Venus clam (Anomalocardia brasiliana) (Gmelin, 1791) (Bivalvia: Veneridae) in Brazil, and points out strategies to improve the system. Venus clam is a small and commonly exploited species for food and income on the Brazilian coast. This research was carried out at Ponta do Tubarão Sustainable Development Reserve (Brazilian Northeast coast), where there was no information available about who harvest, where or how much Venus clam has been harvested, despite this resource being exploited for generations. Clam fishery follows the pattern of socio-economic invisibility that general clam exploitation has in Brazil. Methods used were interviews, participatory monitoring and focal follow observation from January 2010 to May 2011. Results include: (a) the identification of shell fishers, (b) how harvest and meat processing are performed (mollusk beds, time spent, gross and net production), (c) the analisis of shell fisher income and their economic sustentability, and (d) the involvement of shell fisher families in data gathering and analyses for the first time. Based on the acquired knowledge, we propose a new institutional arrangement for clam fishery including co-management, fisheries agreement, compensatory arrangements and improvements for the Venus clam value chain such as the establishment of a minimum price for clam meat. This research also includes two other results: a general description for Venus clam harvesting in the Brazilian Northeast coast and a specific discussion about co-management of Venus clam in Brazil. The first one was possible through the meeting of several shell fisherwomen from other states during activities promoted by People of the Tides (PoT) project. PoT was an international initiative aiming to develop coastal communities that depend on mollusk for their livelihood. The second one is a comparison between PoT and Venus clam management at Pirajubaé Marine Extractive Reserve (Santa Catarina). It evaluates the success and failures of these only two initiatives involving co-management of A. brasiliana in Brazil

De baixo para cima: implicações socioespaciais da transferência da feira livre na (re)produção do espaço urbano de Nova Cruz-RN (1991-2010)

The present work is about the reproduction of the urban area of Nova Cruz RN, with the objective of analyzing the social and spatial implications of the relocation of the main street market in the city from 1991 on. Nowadays, the city of Nova Cruz takes over importance in the potiguar social and spatial scenario due to its condition of central city which is practiced for decades in Potiguar Agreste Microregion. Beginning with its formation process connected with traveler‟s hostel which assisted the activity of cattle transportation, further in time by the golden era of cotton production in its territory, it was noticed that its importance in relation with the nearby towns has been happening differently throughout time. From the year 1991 on, the town of Nova Cruz has gone through a territory restructuring of its urban area due to the relocation of the open market from Downtown neighborhood to São Sebastião neighborhood. Such territorial movement resulted in a reformation of the town‟s urban space, promoting in both neighborhoods urban growth and the expansion of commercial activity associated with the migration of the commercial center of the city. The transference of the commercial area has caused these processes through the new uses of the land towards the São Sebastião region, it has also caused a decrease in market value of the downtown area as a result of the breakdown of previous existing business activities, their service contribution and the citizen migration, establishing a space and socioeconomic portrait in the neighborhood. From this context, our analysis seeks to understand the social and spatial impacts occurred in Downtown neighborhood, the way in which the production and reproduction of the urban space in São Sebastião neighborhood and the implications resulted from the actions of the administrative power in restructuring of the urban space of Nova Cruz. In order to do so, a bibliographical research was used to compose our theoretic-conceptual mark, discussing the matter with authors such as Roberto Lobato Corrêa, Ana Fani, Milton Santos, Manuel Castells e Heri Lefvbre, among others, discussing on the subject of urban analysis, the concepts of urban space and the process of reproduction of the urban space. A field research was utilized in our area of study by means of primary data gathering through interviews, questionnaire and photographic register. Secondary data gathering was also obtained by means of bibliographical and documental research related to our study object. By these means, it was sought to contribute to the understanding of the urban space through its production and reproduction based upon the discovery of social and spatial practices

Reliability and validity of self-reported burnout in college students: A cross randomized comparison of paper-and-pencil vs. online administration

Internet data collection is becoming increasingly popular in all research fields dealing with human perceptions, behaviors and opinions. Advantages of internet data collection, when compared to the traditional paper-and-pencil format, include reduced costs, automatic database creation, and the absence of researcher-related bias effects, such as availability and complete anonymity. However, the validity and reliability of internet gathered data must be established, in comparison to the usual paper-and-pencil accepted formats, before an inferential analysis can be done. In this study, we compared questionnaire data gathered from the internet with that from the traditional paper-and-pencil in a sample of college students. The questionnaires used were the Maslach Burnout Inventory - Student Survey (MBI-SS), the Oldenburg Burnout Inventory (OBI-SS) and the Copenhagen Burnout Inventory (CBI-SS). Data was gathered through a within-subject cross randomized and counterbalanced design, on both internet and paper-and-pencil formats. The results showed no interference in the application order, and a good reliability for both formats. However, concordance between answers was generally higher in the paper-and-pencil format than on the internet. The factorial structure was invariant in the three burnout inventories. Data gathered in this study supports the Internet as a convenient, user-friendly, comfortable and secure data gathering method which does not affect the accepted factorial structures existent in the paper format of the three burnout inventories used.
