Jméno: Bc. Lucie Hélová Vedoucí práce: Mgr. Roman Gabrhelík Ph.D. Title: Evaluation of formal accuracy and content on the risk behavior of the webpages of pedagogical and psychological counseling centers in the Czech Republic in 2016 ABSTRACT The thesis describes the evaluation of formal accuracy and content about the risk behavior of the websites of pedagogical and psychological counseling in the Czech Republic. Since information technology is today one of the main tools for obtaining information, it is necessary to address the quality of internet presentations. The aim of the research is to evaluate the formal and content levels of the websites of pedagogical and psychological counseling through research and content analysis. The theoretical part of this thesis is based on professional literature, both Czech and foreign experts. It deals with risk behavior from the point of view of addictology, pedagogical- psychological counseling, its purpose and position in the education system. Practical part deals with practical research, which was realized by questionnaire survey. Within the stated objectives, it was found that all PPPs in the Czech Republic use a website for their presentation. Their quality is generally very variable and even the most successful ones have not reached 70% of the possible points....

Doctor of Philosophy / Hospitality Management and Dietetics / Rebecca A. Gould / Chihyung Ok / The Internet has been one of the primary channels for acquiring information during pre-purchase and actual purchase stages characterized by easy entry and low supplier power. Internet travel businesses find it harder to retain customers, and customer defection to better alternatives is inevitable. Travel website developers and/or managers face problems that make it necessary to understand and identify what makes their customers continue to use websites without switching. To date, much attention has gone to identifying what affects website users’ behavioral intentions. Limited research, however, has been published on the experiential value of using travel websites and what influences travelers to switch to other travel websites, a context that requires more information. The purpose of this study was to explore and test travelers’ loyalty empirically, along with determinants like the value of travel websites and website switching drivers. In particular, Study 1 proposed a theoretical model identifying the effects of a website’s experiential value on satisfaction, and, in turn, attitudinal loyalty and behavioral loyalty. Study 2 aimed to examine website switching factors (i.e., switching costs, attractiveness of alternatives, and perceived network externality) on the relationship between satisfaction and loyalty. Along with the purpose and objectives of the study, 14 hypotheses were proposed based on the literature review. Data were collected from 384 travel website users in the United States who are 18 years or older and have used travel websites within the last three months. The proposed relationships were examined using structural equation modeling and hierarchical multiple regression analysis. Results showed that customer return on investment, service excellence, and aesthetics were directly associated with satisfaction; satisfaction was directly related to attitudinal loyalty and behavioral loyalty; attitudinal loyalty showed a positive influence on behavioral loyalty; and attitudinal loyalty partially mediated the relationship of satisfaction with behavioral loyalty. Further, the results of this study revealed that switching costs, attractiveness of alternatives, and perceived network externality were significantly and positively associated with loyalty, but their interaction effects with satisfaction on loyalty were not significant. The findings should add to the understanding of travelers’ value perception of travel websites and website switching behaviors. In addition to its contribution to the literature, online travel and tourism businesses or organizations benefit from suggestions of practical applications for retaining customers.

abstract: Phishing is a form of online fraud where a spoofed website tries to gain access to user's sensitive information by tricking the user into believing that it is a benign website. There are several solutions to detect phishing attacks such as educating users, using blacklists or extracting phishing characteristics found to exist in phishing attacks. In this thesis, we analyze approaches that extract features from phishing websites and train classification models with extracted feature set to classify phishing websites. We create an exhaustive list of all features used in these approaches and categorize them into 6 broader categories and 33 finer categories. We extract 59 features from the URL, URL redirects, hosting domain (WHOIS and DNS records) and popularity of the website and analyze their robustness in classifying a phishing website. Our emphasis is on determining the predictive performance of robust features. We evaluate the classification accuracy when using the entire feature set and when URL features or site popularity features are excluded from the feature set and show how our approach can be used to effectively predict specific types of phishing attacks such as shortened URLs and randomized URLs. Using both decision table classifiers and neural network classifiers, our results indicate that robust features seem to have enough predictive power to be used in practice. / Dissertation/Thesis / Masters Thesis Computer Science 2017

Purpose - The purpose of this study was to explore how companies that sell household services work with trust-enhancing measures. We reviewed the industry segment of meal kit companies and aimed to generate findings representative for this industry. Methodology - The study applied a qualitative research methodology where seven semi-structured interviews with company representatives were held. Findings - Trust-enhancing measures were performed when the companies emphasised competence through their communication of company values, values connected to high grocery quality, the work behind recipe creation and lastly by providing educational content which portrayed them as the experts. Another trust-enhancing measure was the use of consumer reviews. Implications - For household service companies to enter the consumer’s personal sphere, enhancing trust is key. This can be done through conveying that the companies have the expertise needed to fulfil their promise - this to assure the consumer that he or she does not need to worry. Contribution - To the best of our knowledge, few studies have considered company trust- enhancing measures within the context of outsourcing household services. Consequently, we hoped to contribute to literature and shed light on this phenomenon.

Different models of sites analyses with diverse central points came up in the academy with focus which alternate themselves between the evaluation of the technological aspects and the quality measurement perceived by the user or consumer. In this research, the WebQual device was used, which was created by Loiacono (2000), and it has the privilege of evaluating the sites quality through the user´s or consumer´s view. The present research aims to evaluate the sites quality of the hotels in the Paraíba capital in the users´perception, and taking into account the WebQual model constructs which are use facility, usage, interactivity and complementary relation. The main factors, present in the sites, were identified in order to find out which ones motivate the users to visit them again. A non-random sample, obtained by the accessibility and convenience criterion was made up with guests and non-guests who are users of the sites, with a total sum of 377 who were interviewed. The survey was carried out by means of structured questionnaire and the results were analyzed through a data descriptive analysis, a confirmatory factorial analysis, a structural equation model technique and multiple linear regression. The constructs demonstrated convergent and discriminatory validity and, compound trustworthiness, in addition to pointing out the positive influence of the utility, of the online operations as well as the entertainment when revisiting the hotel sites. The results obtained by this survey enabled the suggestion of adjustments in the WebQual model for its application. / A avaliação da qualidade de sites na Internet é hoje, tópico de estudo de vários pesquisadores em todo o mundo. Diferentes modelos de análises de sites com enfoques variados surgiram na academia com focos que se alternam entre a avaliação dos aspectos tecnológicos e a medição da qualidade percebida pelo usuário ou consumidor. Nesta pesquisa, optou-se por utilizar o instrumento WebQual, criado por Loiacono (2000), o qual privilegia a avaliação da qualidade dos sites pela ótica do usuário ou consumidor. A presente pesquisa busca avaliar a qualidade dos sites dos hotéis da capital paraibana na percepção dos usuários, levando em consideração os construtos do modelo WebQual Facilidade de uso, Usabilidade, Interatividade e Relação complementar. Buscou-se identificar quais são os principais fatores presentes nos sites que motivam os usuários a visitá-los novamente. Uma amostra não-aleatória, obtida pelo critério de acessibilidade e conveniência foi constituída com hóspedes e não hóspedes usuários dos sites, totalizando 377 entrevistados. O levantamento foi operacionalizado por meio de questionário estruturado e os resultados analisados por meio de análise descritiva dos dados, análise fatorial confirmatória, por intermédio da técnica de modelagem de equações estruturais e regressão linear múltipla. Os construtos demonstraram validade convergente e discriminante e, confiabilidade composta, além de apontar a influência positiva da utilidade, das operações online e do entretenimento na intenção de revisitar os sites dos hotéis. Os resultados obtidos por este levantamento possibilitaram a sugestão de ajustes no modelo WebQual para sua aplicação.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Esta dissertação é a descrição de um trabalho cujo objetivo principal foi a criação de um site com materiais sobre o tema preconceito linguístico, visando a promover uma circulação do conhecimento científico entre diversas classes da sociedade não-acadêmica. Nossas primeiras motivações para a realização de um trabalho desse tipo se iniciaram após a polêmica ocorrida em 2011 sobre o livro didático que, segundo a mídia, ensinaria os alunos a falar errado. Essa situação demonstrou existir uma falta de diálogo entre academia e sociedade no que concerne a temas sociolinguísticos. Percebemos uma necessidade de se realizar uma divulgação científica que chegasse com sucesso à sociedade, de modo que as pessoas pudessem conhecer o assunto em questão e, ao menos, refletir sobre ele. Muito embora já existam trabalhos realizados por linguistas com essa intenção, como é o caso de Bagno (1997, 1999), Bortoni-Ricardo (2004, 2005) e Scherre (2005), estes ainda são limitados, por serem, em sua maioria, livros e artigos acadêmicos. Utilizando como base o princípio de indissociabilidade entre ensino, pesquisa e extensão (MEC/SESu, 2006), buscamos, segundo o próprio princípio exige, unir a pesquisa científica resultante dos estudos sociolinguísticos à extensão - através da divulgação do tema para as pessoas de fora do meio acadêmico - e ao ensino, criando e compartilhando materiais que possam ser também utilizados em sala de aula. Para conquistar tal objetivo, tendo como inspiração a proposta de Baronas (2010) e seguindo os exemplos de Ribeiro (2006), Chagas (2012) e Pauleto (2013), criamos um site com materiais diversos sobre o tema preconceito linguístico, como vídeos, imagens e textos informativos. Ainda, como complemento do trabalho, foi criada uma página no Facebook, de modo a obter uma eficácia maior na divulgação, sabendo que a internet é hoje um dos meios mais fáceis, rápidos e de longo alcance para o compartilhamento de informações. Tivemos por intenção promover uma circulação do conhecimento, aplicando o princípio da gratuidade linguística apresentado por Wolfram (1998) e assumindo um papel de agentes de mudança social, segundo aponta Charity (2008). De modo a verificar a eficácia de nosso trabalho, utilizamos uma avaliação em modelo de questionário de escala Likert, realizada por três grupos distintos de avaliadores. Nossos resultados mostraram aprovação ao site por parte dos três grupos de avaliação, demonstrando que esse tipo de trabalho é eficiente e promissor, sendo uma maneira eficaz e ampla de se promover a circulação de saberes sociolinguísticos e divulgar uma mensagem de combate ao preconceito linguístico / This dissertation is the description of a work whose main objective was the creation of a website with materials about the linguistic prejudice subject, with the intention of promoting a circulation of scientific knowledge among several classes of the non-academic society. Our first motivations for the achievement of a work of this kind initiated after the controversy occurred in the year of 2011 about a schoolbook which, according to the press, would teach students to speak wrongly. This situation showed an existing absence of dialogue between academy and society regarding to sociolinguistic subjects. We noticed the need of making a scientific communication that could reach the society successfully, in order to make people know about the subject and, at least, reflect about it. Even though there are already many works made by linguists with this same purpose, like Bagno (1997,1999), Bortoni-Ricardo (2004, 2005) and Scherre (2005), these are already very limited, for being, in the majority, books and academic articles. Making use as our basis of the indivisibility principle between teaching, research and extension (MEC/Sesu, 2006), we aimed to unite the resulting scientific research of the sociolinguistic studies to the extension with the divulgation of the subject to the people that are out of the academic environment and to the teaching, creating and sharing materials that can also be used in the classroom. To achieve such objective, having the idea suggested by Baronas (2010) as our inspiration and following the examples of Ribeiro (2006), Chagas (2012) and Pauleto (2013), we created a website with several materials about the linguistic prejudice subject, such as media clips, pictures and informative texts. As a complement of this work, we also created a Facebook page, in order to reach more effective divulgation, knowing that, nowadays, the internet is one of the easiest, fastest and widest ways of sharing information. Our intention was to promote a circulation of knowledge, applying the linguistic gratuity principle, presented by Wolfram (1998), and assuming a role of an agent of social change, according to Charity (2008). In order to verify the effectiveness of our work, we used an evaluation in the models of a Likert scale questionnaire, answered by three different groups of evaluators. Our results showed that the website was approved by the three evaluation groups, showing that this kind of work is efficient and promissory, being an effective and wide way of promoting the circulation of knowledge and the divulgation of a message against linguistic prejudice

Consistindo no processo de compartilhar um problema com os usuários de alguma comunidade online e aguardar por respostas. Para obter uma resposta satisfatória, é necessário que alguém apto e disposto a ajudar visualize a requisição. Entretanto, isto nem sempre é facilmente alcançado. Neste sentido, as pesquisas sobre o tema têm se concentrado em propor técnicas de roteamento de perguntas, argumentando que o direcionamento do problema para especialistas atrai atenção destes e garante respostas com qualidade. Entretanto, há perguntas que não são direcionadas a ninguém, mas compartilhadas em broadcasting, que também recebem respostas. Algumas pesquisas recentes identificaram que certas características da pergunta podem ser determinantes para estimar se a mesma será respondida ou não. Na pesquisa ora apresentada, foi realizada uma consulta à comunidade dos Sites de Perguntas e Respostas de Programação, a fim de identificar quais características os usuários levam em consideração, ao escolher quais perguntas responder. Como resultado da consulta, foi elaborado um guideline contendo 16 sugestões de características “boas” que uma pergunta sobre programação poderia ter mais chances de ser respondida. Em seguida, foram realizados estudos a fim de julgar a correlação que a presença das características tinha com o desempenho (número de visualizações recebidas, número de respostas recebidas, tempo até obter a primeira resposta) das perguntas que eram publicadas. Os estudos revelaram apenas correlações muito fracas entre as variáveis testadas, indicando, por exemplo, que a presença de mais dessas características não garante mais respostas ou respostas em menos tempo, mesmo que a comunidade julgue que a inclusão dessas seja importante. / The social query is a way to find information in social media age. It is the process of sharing a problem with the user of an online community and waiting for answers. Getting help demands that someone able and willing to help perceives the request. However, this is not always easy. In this context, the literature about this theme has focused in proposing question routing techniques, arguing that directing the problem to experts warns their attention and guarantees high quality answers. However, there are questions that are directed to nobody, but broadcasted, that also receive answers. In this research, we ask the community from Question and Answering Sites about Programming which characteristics they expect in questions they choose to respond. We gathered these answers and created a guideline with 16 suggestions on how to include “good” characteristics in the question. Next, we evaluated how the presence of more of these characteristics was correlated with the question performance (considering features like the number of views, number of answers and time for first response). We found very weak correlations only; thus, indicating that the presence of more of these characteristics has no meaningful impact, even if the community believes it does.
