Métodos de coleta de dados: análise comparativa dos perfis dos respondentes e dos resultados obtidos via internet e via presencial face a face

Calliyeris, Vasiliki Evangelou 23 May 2012 (has links)
Made available in DSpace on 2016-04-25T16:44:28Z (GMT). No. of bitstreams: 1 Vasiliki Evangelou Calliyeris.pdf: 1496420 bytes, checksum: a342b524a305e962cb1286f267c52268 (MD5) Previous issue date: 2012-05-23 / This work has as objective analyze comparatively the respondents profile and the results obtained by two different data collection approaches: by internet (online) and face to face at home (offline). The criteria selected for this comparison were the response return rate for both methods, the answers quality obtained on the attributes evaluation questions and the results on habits and attitudes of the selected samples. The first two chosen criteria refer to a topic very discussed in the academy that is the relationship between the respondent and the electronic data collection method, on which is believed to be uncontrolled, causing low access rate and also compromising the quality of data collected. The last criteria selected refers to another theme approached by academics which is the respondents profile that both data collection methods reach, which is believed to be distinctive and in consequence, provides differences in consumption behavior of the approached targets. To reach the proposed objectives, initially some in depth exploratory interviews were conducted with executives of research institutes acting in Brazil, aiming to understand their point of view regarding the capability of the online research method. Subsequently a quantitative study was conducted through two data collection methods, electronic by internet and face to face at home, with two different samples, which results were compared. The hypotheses were confirmed once there were differences in answers return rates, bias on attributes evaluation caused by one of the targets and also differences in both social-demographic profiles that reflected in discriminant consumption habits and attitudes. This work is justified in a way that it presents a current and controversial subject in the academy and in the business world, which focus is debate the replace of the traditional date collection methods by the contemporary one by internet, or even its complementarity, in a moment that the virtual network is increasing its penetration in the relationship company-consumer / O presente trabalho tem por objetivo analisar comparativamente o perfil dos respondentes e os resultados advindos de duas abordagens distintas de coleta de dados: via internet (online) e via presencial face a face domiciliar (offline). Os critérios selecionados para essa comparação foram o índice de retorno das respostas de ambos os métodos, a qualidade das respostas obtidas nas baterias de avaliação de atributos e os resultados de comportamento e atitudes das amostras selecionadas. Os dois primeiros critérios escolhidos referem-se a um tema muito discutido na academia que é a relação do respondente com o método de coleta eletrônico, sobre a qual acredita-se não haver controle, o que pode ocasionar um baixo índice de adesão e também comprometer a qualidade dos dados coletados. O último critério selecionado refere-se a outro tema muito debatido que é o perfil de respondente que ambos os métodos de coleta alcançam, que acredita-se ser distinto e, em consequência, reproduz diferenças de comportamento de consumo e de atitudes entre os dois públicos abordados. Para se alcançar os objetivos propostos, em primeiro lugar foram realizadas entrevistas em profundidade exploratórias com executivos de institutos de pesquisa atuantes no Brasil, com o intuito de se entender seus pontos de vista em relação à aplicabilidade do método de coleta online. Posteriormente, conduziu-se um estudo quantitativo por meio de dois métodos de coleta, eletrônico via internet e presencial face a face, com duas amostras distintas, cujos resultados foram comparados. As hipóteses levantadas foram confirmadas, uma vez que houve divergência entre os índices de retorno das respostas obtidas, viés no preenchimento das baterias de atributos por um dos públicos, e também diferenças no perfil sociodemográfico das amostras abordadas, que refletem padrões de consumo e de comportamento distintos entre ambas. Este trabalho justifica-se na medida em que apresenta um tema atual e controverso no ambiente acadêmico e corporativo, cujo foco é debater a substituição dos métodos de coleta tradicionais pelo método contemporâneo via internet, ou sua complementaridade, em um momento no qual a rede virtual de comunicação ganha cada vez mais espaço na relação empresa-cliente

No. of bitstreams: 1 Camila Lopes Garcia.pdf: 4300232 bytes, checksum: e034c96be58a34dffa252f8d510f93ba (MD5) Previous issue date: 2010-10-18 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The research Collections of floating images: digital online photo albums analyzes the photo collections in the passage of the secondary media to the tertiary media, that is, the transition of the traditional photo album to the digital online photo album put in the social network services, such as Orkut, Facebook and Flickr. The transformations on the amateur photographic habits are analyzed, concerning the filing logic and its social function, due to the technological substitution and the individualization of the machine that produces images. To do so, based on historical and theoretical perspectives, the image is taken in relation to death from the rupestrian paintings to the techno-images, part of Ivan Bystrina s, Edgard Morin s, Régis Debray s and Hans Belting s studies and the sharing of private life photo albums in digital environment, sustained on Vilém Flusser s concepts of no thing , greed and cosmic brain , Norval Baitello s iconography, Dietmar Kamper s visibility crisis , Eugênio Trivinho s ideia of real time existence and Jean Baudrillard s concept of simulacrum . Three digital online photo albums were analyzed, which made possible the identification of two different analyses categories of photo collections on the internet: the ones that give real existence to the network member s profile and the ones that contribute to a common world mapping, due to the use of a search model, or information recovery, by folksonomy tags / A pesquisa "Coleções de imagens flutuantes: álbuns fotográficos digitais on-line" analisa o colecionismo fotográfico na passagem da mídia secundária para a mídia terciária, isto é, na transição do álbum de fotos tradicional para o álbum de fotos digital on-line alocado em redes sociais como o Orkut, o Facebook e o Flickr. São estudadas as transformações ocorridas no hábito fotográfico amador, no que tange à lógica de arquivo e sua função social, em virtude da substituição tecnológica e da individualização do aparelho produtor de imagens. Para tanto, a partir das perspectivas históricas e teóricas, pensa-se a imagem e sua relação com a morte - desde as pinturas rupestres às tecno-imagens, presente nos estudos de Ivan Bystrina, Edgard Morin, Régis Debray e Hans Belting - e o compartilhamento dos álbuns de fotos da vida privada em ambiente digital, apoiando-se nos conceitos de não coisa , gula e cérebro cósmico de Vilém Flusser, na iconofagia de Norval Baitello, na crise da visibilidade de Dietmar Kamper e na ideia de existência em tempo real e simulacro de Eugênio Trivinho e Jean Baudrillard, respectivamente. Três álbuns de fotos digitais on-line foram analisados, o que possibilitou a identificação de duas categorias diferentes de colecionismo fotográfico na internet: os que conferem existência real ao perfil do integrante da rede e os que contribuem para um mapeamento coletivo do mundo, em função da utilização de um modelo de busca, ou recuperação das informações, por meio de tags folksonômicas

Visual trauma: Representations of African bodies in the 1983 Contre Apartheid Exhibition

Petersen, Charlise January 2018 (has links)
Magister Artium - MA (English) / After the 1976 student uprising, South Africa entered a period of increased violent state repression. The struggle against apartheid also became increasingly globalised, as can be seen in the UN resolution and the rise of various international anti-apartheid organisations. My thesis looks at the various ways in which art was used as a response to the crisis of late apartheid in the 1980s, focusing on a landmark international exhibition, the Art Contre Apartheid exhibition which opened in Paris on 1983. It examines the context and history of the Art Contre Apartheid collection, and follows its path to its current location at the Mayibuye Archive at the University of the Western Cape, where it mostly languishes in packing crates. My research locates its analysis of the works in broader debates around art and politics during the struggle years in South Africa, but also to highlights the continuities and contrasts between international responses to apartheid, and local struggle art produced in the period surrounding the launch of the exhibition. Some of most compelling works of art in the collection depict the human form, and register acts of torture. The analysis focuses specifically on depictions of a fragmentation and dismemberment of the human body. Drawing on Elaine Scarry's argument about the limitations of language as an adequate response to trauma, my research develops an analysis of these works that demonstrates how the body becomes a privileged site in which violent political contestations are made visible. The thesis also deals extensively with the 'absence of form', which highlights the various instances in the ACA collection where abstract art was used as a signifier of pain, and thus the unspeakable effects of apartheid.

The Swedish American Bibliography Project. A Case Study

Jansson, Martha January 2007 (has links)
This thesis is a case study of the Swedish American Bibliography (SWAM), a special subject database in the Swedish Royal Library’s library information system, LIBRIS. The research intentions are to explore and define the bibliography, and, by resolving issues concerning the responsibility for the bibliography, to fulfill the broader intention of clearing the way for its continuation. During the academic year 2006/2007 the qualitative methods of literature analysis, website analysis, email interviews and correspondence were used for investigating the bibliography. Results of research question one showed the SWAM bibliography’s beginnings and its basis in Swedish cultural heritage. Results of research question two showed the bibliography’s relationship to the Royal Library’s duties and instructions. Results of research question three showed the organization of knowledge in the bibliography’s scope, its digital structure and its accessibility. Results of research question four compared the bibliography to similar Nordic bibliographies. Results of research question five covered the Swedish and North American institutions collaborating on the project to keep the bibliography going and addressed the project member institution representatives’ ideas for the bibliography’s future. In addition to the bibliography material’s significance for Swedish cultural heritage, the conclusions revolved around the need for a combination of open communication channels among the member institutions, a sound financial base of operations and strong leadership and around the Royal Library’s ultimate head responsibility for the SWAM bibliography’s continuation. / Uppsatsnivå: D

Assertion and accommodation : a study of the assertive language in the conversations of school-age (5-13 years) girls

Topham, Emma January 2018 (has links)
This study aimed to investigate the use of accommodation of assertive utterances (AUs) in the conversations of 49 girls aged 5;0-13;1. Based on the findings of earlier research that the use of such language is more closely related to age than to gender, it was predicted speakers would accommodate their use of and response to assertive utterances as a result of their partner's age. Naturalistic language from these speakers was collected over a year, and evidence of accommodation was observed in all speakers. Fewer AUs were used with younger speakers compared to older ones, and those used with younger girls were more likely to be produced with the sole purpose of controlling the hearer's behaviour. In addition, AUs were more likely to be complied with, or accepted, when they were produced by older girls. Given what is known about the types of language used by powerful/powerless individuals, it appears that these speakers consider age to be an indicator of status. A particularly interesting finding was that it was the age of a speaker in relation to other members of the conversation that influenced their use of and response to AUs, rather than the age of the speaker alone.

Naturen-Minnen från en kvällsvandring / Nature

Ekström, Matilda January 2012 (has links)
Naturen är ett undersökande arbete i att uttrycka och materialisera en stämning baserat på minnen från en kvällsvandring. Jag gestaltar upplevelsen och materialiserar den i textil. Genom att undersöka möten mellan olika textila tekniker vill jag skapa en kollektion som ger en förnimmelse av min naturupplevelse. Text ur Caroline Ringskog Ferrada-Nolis bok Naturen har varit utgångspunkt vid uppbyggnaden av kollektionen. Resultatet är en dynamisk textilkollektion för hemmiljö som innehåller digitaltryck, ausbrenner jacquardväv och en stickad struktur.Nature is an exploratory work on expressing and materializing a mood based on the memories of a night walk. I portray the experience and materialize it into fabric. By examining the interaction between different textile techniques, I create a collection that gives a perception of my experience of nature. Text from Caroline Ringskog Ferrada-Nolis book Naturen has been the starting point in building up the collection. The result is a dynamic collection of textiles which includes digital printing, ausbrenner, jacquard weaving and a knitted structure. / Program: Textildesignutbildningen

Os livros eletrônicos e as bibliotecas / -

Serra, Liliana Giusti 06 July 2015 (has links)
Esta pesquisa discute a utilização de livros eletrônicos em bibliotecas e as transformações que este recurso pode ocasionar em unidades de informação e nas atividades bibliotecárias. Para tanto são analisadas as transformações pelas quais passou o livro, em seus suportes e formatos, passando pelas ideias de Vannevar Bush, o Dynabook, primeiro dispositivo de leitura e a oferta de conteúdo do Projeto Gutenberg até o advento do livro eletrônico. As denominações empregadas para designar os livros eletrônicos são identificadas e busca-se conceituar o objeto empírico. São identificados seus quatro elementos, formato, dispositivo, plataforma e DRM, e as transformações ocorridas no processo de aquisição, com a possibilidade de licenciamento do conteúdo em oposição à propriedade. Neste aspecto são analisadas as teorias da primeira venda e do uso justo e a implicação que os licenciamentos representam às bibliotecas. São identificados os tipos de fornecedores de conteúdo digital licenciado, editores, agregadores e distribuidores, e as possibilidades de acesso às plataformas e aos conteúdos contratados. Os principais modelos de negócios são apresentados, aquisição perpétua, assinatura, Aquisição Orientada ao Usuário (DDA), Empréstimo de curto prazo (STL) e Aquisição orientada por evidência (EBS), além das possibilidades de inclusão de conteúdo aberto. A partir das características dos modelos de negócios para aquisição de conteúdo licenciado, aspectos do desenvolvimento de coleção são analisados, buscando identificar questões significativas nas práticas bibliotecárias. O texto finaliza com levantamento de vantagens e desvantagens da aplicação de livros eletrônicos em bibliotecas e a importância da continuidade de estudos sobre este tema. / This research discusses the applicability of electronic books (e-books) in libraries and the transformations that this resource can provide in information units and librarianship activities. To do that, are analyzed the book transformations, in its supports and formats, through the ideas of Vannevar Bush, the Dynabook, the first electronic reader and the content offer provided by Gutenberg Project until the evolution of e-book. The various ways in which the ebooks are denominated are presented, seeking for the concept the empirical object. Are identified the four elements of the e-book: the format, the device, the platform and the DRM, and the transmutation in the acquisition process, with the possibility of content licensing as opposed to property. In this aspect, the theory of first sale and the fair use are analyzed and its implications for libraries. From the identification of types of digital content providers, as editors, aggregators and distributors, and the access to platforms and content, the main business models are analyzed, Perpetual acquisition, Signature, Demand Driven Acquisition, Short Term Loans and Evidence Based Selection, addition of open access. From the business models characteristics to acquire digital content, are analyzed some aspects of collection management, trying to identify significant questions about the libraries practices. The text ends with the advantages and disadvantages of the e-books adoption in libraries and the importance of continuing studies on this topic.

Targeted feedback collection for data source selection with uncertainty

Cortés Ríos, Julio César January 2018 (has links)
The aim of this dissertation is to contribute to research on pay-as-you-go data integration through the proposal of an approach for targeted feedback collection (TFC), which aims to improve the cost-effectiveness of feedback collection, especially when there is uncertainty associated with characteristics of the integration artefacts. In particular, this dissertation focuses on the data source selection task in data integration. It is shown how the impact of uncertainty about the evaluation of the characteristics of the candidate data sources, also known as data criteria, can be reduced, in a cost-effective manner, thereby improving the solutions to the data source selection problem. This dissertation shows how alternative approaches such as active learning and simple heuristics have drawbacks that throw light into the pursuit of better solutions to the problem. This dissertation describes the resulting TFC strategy and reports on its evaluation against alternative techniques. The evaluation scenarios vary from synthetic data sources with a single criterion and reliable feedback to real data sources with multiple criteria and unreliable feedback (such as can be obtained through crowdsourcing). The results confirm that the proposed TFC approach is cost-effective and leads to improved solutions for data source selection by seeking feedback that reduces uncertainty about the data criteria of the candidate data sources.

Many of the objects of his collection were given by friends, others were found in the beach, others were bought. Neruda, by his poetry, managed to materialize the image of what was seeing by observing his objects, in special some shells that were part of his collection of snail (as he said). In this dissertation, we present some aspects related to the confluence between poetry and science. To do so, we compare the poetic description of the shells, with description in scientific form. The poetic language differs in relation to the use of words but is no less true / Pablo Neruda, além de escrever poesia e de participar da vida política do Chile, costumava colecionar os mais variados objetos, coletados nas mais diversas formas, em vários lugares por onde viajou, enquanto representante diplomático daquele país. Muitos dos objetos de sua coleção foram recebidos de amigos, outros foram encontrados na praia e outros, ainda, foram comprados. Neruda, através da poesia, esforçou-se em materializar as imagens que estava captando ao observar os seus objetos, em especial algumas conchas que faziam parte de sua coleção de caracóis (como ele mesmo identifica). Nesta dissertação, procuramos apresentar alguns aspectos relacionados à confluência entre poesia e ciência. Para tanto, buscamos comparar a descrição poética das conchas, com descrição na forma científica. A linguagem poética difere em relação à utilização das palavras porém não é menos verdadeira

Caracterização do trabalho da enfermagem em laboratório de análises clínicas / Characteristics of the activities performed by nursing professionals in clinical laboratories.

Silva, Adriana Marques da 12 March 2004 (has links)
Este estudo de caráter qualitativo e quantitativo, tipo exploratório-descritivo, trata da caracterização do trabalho de enfermagem em laboratórios de análises clínicas. O objetivo geral visa identificar os aspectos da atuação da enfermagem nos laboratórios de análises clínicas, que permitam caracterizar o processo de trabalho da enfermagem. Os objetivos específicos buscaram identificar os trabalhadores da saúde que atuam na coleta de exames; reconhecer as atividades desempenhadas pelos diferentes agentes da enfermagem e conhecer sua inserção na estrutura organizacional. O referencial teórico adotado pautou-se nos estudos do processo de trabalho e de recursos humanos em saúde e em enfermagem. Para a coleta de dados utilizou-se um questionário e a amostra foi composta por 45 instituições. A análise dos resultados revelou que, quanto à caracterização dos laboratórios, 15,6% não realizam treinamento em serviço e 60% fazem-no de modo isolado, não continuado; o enfermeiro é o profissional que assume majoritariamente a responsabilidade por essa ação. Quanto aos recursos humanos, 77,8% são auxiliares de enfermagem, 13% enfermeiros e 9,1% técnicos de enfermagem. Evidencia-se a divisão social e técnica do trabalho, no qual os auxiliares executam o cuidado direto, o enfermeiro gerencia o processo e os técnicos desempenham ambas ações, sem diferenças relevantes entre as atividades dos auxiliares e técnicos de enfermagem. Além disso, há outros profissionais que compartilham das mesmas atividades realizadas pela enfermagem e esta se encontra, em grande parte, subordinada a outras áreas de atuação, com escassa autonomia na estrutura organizacional. / This qualitative and quantitative study, an exploratory-descriptive study, examines the characteristics regarding the work performed by nursing professionals in clinical laboratories. The general goal aims to identify roles played by nursing professionals in clinical laboratories that allow us to characterize the nursing work process. The specific goals seek to identify health workers that are responsible for collecting samples, to distinguish the activities played by different nursing professionals and to learn how they are inserted in the organizational structure. The theoretical reference adopted is based on studies regarding work procedures and human resources in health and nursing. A questionnaire was used to collect data and the sample comprised 45 institutions. Regarding the clinical laboratories, result analysis revealed that 15.6% of them do not offer in-service training and 60% do not do it on a continuous manner; nurses basically take on the responsibility for training other nursing professionals. Regarding human resources, 77.8% are nursing assistants, 13% are nurses, and 9.1% are practical nurses. There is evidence of a social and technical division of the workload: nursing assistants provide direct care, nurses manage the processes, and practical nurses perform both activities. No relevant differences were observed between the activities played by nursing assistants from those played by practical nurses. Furthermore, there are other professionals that share the same activities played by those nursing professionals. In most cases, nursing professionals are subordinated to other areas and have little autonomy in the organizational structure.
