En esta investigación, abordaremos las tácticas atenuantes que funcionan por medio de actividades metaenunciativas, entre las que se destaca una por poner en evidencia la presencia del otro en el discurso del hablante. De este modo, el objetivo general del presente trabajo es describir y analizar las estrategias de atenuación llevadas a cabo por procedimientos metaenunciativos de esa naturaleza en las interacciones cara a cara desde los fundamentos de la Lingüística Interaccional en diálogo con la Teoría de la Enunciación. El corpus de análisis está compuesto de segmentos de habla extraídos de entrevistas del Proyecto NURC/RJ (Proyecto de Estudio de la Norma Lingüística Urbana Culta de la ciudad de Río de Janeiro) y el enfoque metodológico es principalmente el cualitativo, aunque sin descuidar el análisis cuantitativo cuando este se muestra relevante para la explicación de los fenómenos estudiados. Los resultados de la investigación señalan que la expresión atenuante se corresponde con la propia expresión metaenunciativa cuando esta revela una no coincidencia del discurso consigo mismo (AUTHIER-REVUZ, 1998; 2004), lo que nos permite denominar a dicha estrategia lingüística como atenuación metaenunciativa, que se caracteriza sobre todo por la táctica de la ocultación del yo de la enunciación (BRIZ, 2012; ALBELDA et al., 2014) y se manifiesta en diferentes grados. / A atenuação linguística é uma estratégia discursiva que objetiva mitigar a força ilocucionária dos enunciados e o papel dos atores enunciativos atendendo a fins argumentativos na interação (BRIZ e ALBELDA, 2013). Nesta pesquisa, trataremos dos recursos atenuantes que operam por meio de atividades metaenunciativas, dentre as quais se destaca uma por colocar em evidência a presença do outro no discurso do falante. Assim, o objetivo geral do trabalho é descrever e analisar as estratégias de atenuação, realizadas por procedimentos metaenunciativos dessa natureza, nas interações face a face à luz de fundamentos da Linguística Interacional articulada com a Teoria da Enunciação. O corpus de análise é composto por segmentos de fala extraídos de inquéritos do Projeto NURC/RJ (Projeto de Estudo da Norma Linguística Urbana Culta da cidade do Rio de Janeiro) e a abordagem metodológica é eminentemente qualitativa, mas sem descurar da análise quantitativa quando esta se mostrar relevante para a explicação dos fenômenos em estudo. Os resultados da pesquisa apontam que a expressão atenuadora corresponde à própria expressão metaenunciativa quando esta revela uma não-coincidência do discurso consigo mesmo (AUTHIER-REVUZ, 2004;1998), o que nos autoriza a denominar essa estratégia linguística de atenuação metaenunciativa, que se caracteriza, principalmente, pelo recurso da ocultação do eu enunciativo (ALBELDA et al., 2014; BRIZ, 2012) manifestado em diferentes graus.

The dialogical plait in individual vocal education Thesis in Music Education by Jannike Huss. Part of the work for the master´s degree. Studies from School of Music, Theatre, and Art, University of Örebro, 2010. Available from Örebro University, SE-701 82 Örebro, Sweden. Original in Swedish. This thesis treats the value of communication for individual vocal education on a higher level. The purpose is to examine and illuminate what is happening in the interaction between teacher and student in individual vocal education, and how it in turn can affect learning. To get deeper knowledge and understanding of the subject, observations of singing lessons and openhearted interviews have been conducted with one teacher and two of her students. During the discussions the participants gave their own views on how an effective communication can occur in the interaction between teacher and student. In this study, only individual lessons in singing on tertiary music education have been studied. The students participating in the study are both prospective teachers with a major in vocals, and it turned out that they already were obvious carriers of two different roles, namely their student role and also their future occupational role. Due to this fact they could experience the interaction from both sides. The interviews with both students were directly connected to their lessons, and after the lessons the teacher was interviewed. All the interviews took shape as open conversations, and have since been transformed into a coherent narrative with a narrative approach in order to create meaning and context (Kvale, 2008; Georgii-Hemming, 2005). Data from the empirical material has been processed, and recounted to a theoretical conceptual framework (von Wright, 2003; Buber, 2004). Keywords: Vocal education, dialogue, interaction face-to-face, intersubjectivity, relationship, teacher training.

The purpose of this study was to explore the relationship between learning styles and the choice of learning environment for Hospitality and Tourism undergraduate students. An anonymous two-part survey was sent to the instructors of Introduction to Hospitality and Tourism Management courses (both online and face-to-face) in four schools in the state of Florida. The survey was designed to gather information related to the following three research questions related to MBTI profiles for undergraduate students in attempt to identify differences between students enrolled in online classes and those in face-to-face classes. In order to determine the probability of predicting course choice behavior of undergraduate Hospitality and Tourism students, the following factors were controlled in this research: age; gender; enrollment status; employment status; university; whether they had taken an online course previously in high school, college, or other places; how many online courses they previously took; and who helped them select the delivery mode of their courses. There were 323 usable responses, which included a majority of the most common types as ESTJ. When the differences between online and face-to-face course students were analyzed through chi-square tests, the results showed significant differences between two groups for all four profiles. Overall, the most common profile for face-to-face students was ESTJ, while the most common profile for online students were ISTP. In order to examine the unique contribution of learning styles on Hospitality and Tourism students’ course choice, a hierarchical logistic regression model was used. The results of the model indicated that only profile one (P1) and profile four (P4) were significant predictors among the four profiles, along with the total number of online courses previously taken. The conclusions suggested that by looking at P1, P4, and toc1, with a 95% confidence level, the probability of students choosing face-to-face classes can be predicted if the students are extrovert, judging, and previously had taken less than five online courses. If learning styles can be determined ahead of time, students can choose appropriate courses, instructors can develop teaching strategies that will match students’ desirable learning styles, and the number of face-to-face and online courses can be adjusted in each program to offer an appropriate number of courses each semester.

This dissertation introduces work on face recognition using a novel technique based on Hidden Markov Models (HMMs). Through the integration of a priori structural knowledge with statistical information, HMMs can be used successfully to encode face features. The results reported are obtained using a database of images of 40 subjects, with 5 training images and 5 test images for each. It is shown how standard one-dimensional HMMs in the shape of top-bottom models can be parameterised, yielding successful recognition rates of up to around 85%. The insights gained from top-bottom models are extended to pseudo two-dimensional HMMs, which offer a better and more flexible model, that describes some of the twodimensional dependencies missed by the standard one-dimensional model. It is shown how pseudo two-dimensional HMMs can be implemented, yielding successful recognition rates of up to around 95%. The performance of the HMMs is compared with the Eigenface approach and various domain and resolution experiments are also carried out. Finally, the performance of the HMM is evaluated in a fully automated system, where database images are cropped automatically.

Virtual teams have emerged as a result of development in communication technologies and the inevitability for companies to compete in the global market. Differentiating features between traditional and virtual teams are minimal face-to-face interaction and a predominant use of technology-enabled communication. The objectives of this research were to investigate critical factors that contribute towards virtual team success and to further assess the role played by trust, communication, conflict and knowledge. Quantitative data collection methodology was employed for this research, using self-administered questionnaires. A total of 64 responses were received from a sample of 75. Most respondents were from South Africa (47%), while the remaining 53% were from India, United Kingdom and China. Four research questions were formulated based on gaps identified during the literature review. Factor analysis was performed by adding the outcomes of each factor and ranking them in descending order to determine the factor that was highly ranked. Based on this analysis, the study concluded that feedback about how well each team member was doing should be viewed as how well the entire team is doing. Moreover, the ability of team members to make good decisions and establishment of interim deadlines linked with celebration of the milestones, were also ranked as critical factors towards virtual teams success. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

Companies worldwide spend millions of dollars on sales training but often fail to address the significant effect of personal attributes of salespeople on sales performance. Grounded in Bandura's self-efficacy theory, the purpose of this quantitative correlational study was to examine the relationship between age, tenure, general self-efficacy, and sales performance among face-to-face salespeople of technology companies worldwide. Understanding this relationship is important to sales managers for predicting sales performance to enhance sustainability. Data were collected from 103 participants between July and September 2019 via a survey link in the largest IT sales professional LinkedIn group. Multiple hierarchical linear regression analysis indicated a significant relationship, F(3,92) = 8.64, p < .001, R2 = .22, between age, length of tenure, general self-efficacy, and sales performance of salespeople. Implications for positive social change include the potential for sales managers to understand the correlates of sales performance better to contribute to the reduction of discrimination when recruiting salespeople of various ages and experience.

This master‘s thesis describes the identification faces in real terms. It includes an overview of current methods of detection faces by the classifiers. It also includes various methods for detecting faces. The second part is a description of two programs designed to identify persons. The first program operates in real time under laboratory conditions, where using web camera acquires images of user's face. This program is designed to speed recognition of persons. The second program has been working on static images, in real terms. The main essence of this method is successful recognition of persons, therefore the emphasis on computational complexity. The programs I used a staged method of PCA, LDA and kernel PCA (KPCA). The first program only works with the PCA method, which has good results with respect to the success and speed of recognition. In the second program to compare methods, which passed the best method for KPCA.

Social networking sites such as Twitter, Facebook and My Space have experience rapid worldwide growth. It is crucial that this global phenomenon be investigated within the South African context. Social networking is a relatively new trend in South Africa and there is a paucity of academic literature on the topic. This quantitative study investigated one of the most popular social networking websites to date, namely Facebook. Facebook is a social networking website which was launched in early 2004. The primary research question focused on determining the usage patterns of South African Facebook users. In specific, the study investigated the purposes for which the site was used, the self-reported substitution of Facebook usage for face-to-face interaction and the relationship between Facebook affinity and Facebook use. A survey research design was used to collect data via an electronic questionnaire posted on Facebook. The theoretical point of departure was post-positivist. Media theories applied to the phenomenon under investigation include the uses and gratifications theory and the theory of the niche. The findings suggest that Facebook is primarily used for its intended purpose of communication. The respondents reported the gratification of versatile (multipurpose) communication. Furthermore, only half of the sample reported privacy concerns regarding Facebook. There was no significant indication that Facebook is a substitute for face-to-face interaction. Half of the sample claimed that their interpersonal contact has increased as a result of Facebook use. In addition, in accordance with expectations, the more affiliated a person is to Facebook, the more they will use Facebook. The findings of this study conform to other studies concerning social networking and provide a South African view of the global phenomenon of social networking websites. / Dissertation (MA)--University of Pretoria, 2010. / Psychology / unrestricted

Since the introduction of mobile devices, alternative language learning methods have been developed and have evolved alongside traditional language classroom education. This has presented academics with the unique opportunity to study new methods of second language acquisition compared to more traditional face-to-face language instruction. The growing technology possibilities have contributed to what is called Mobile Assisted Language Learning (MALL), where learners can easily study a new language with the use of a personal electronic device such as a laptop or phone. Studies about such learning tools, for example Rosetta Stone, Duolingo or Babbel have been carried out for several years to for example test their effectiveness. Among research studies, one well-known study by Vesselinov and Grego (2012) looked at the effectiveness of Duolingo, evaluating the statement Duolingo makes that 34 hours of studying with the tool is equivalent to a semester in a university classroom (Vesselinov & Grego, 2012). Even though various studies about the well-known language learning application (app) Duolingo have been conducted, gaps in research are still present.The current study aims to find out if studying German for one semester (14 weeks) with Duolingo is equivalent to one semester in a beginner face-to-face class, German 101, at a university level. At the end of the semester, both groups took the German 101 final exam and the Duolingo placement test to measure German learning. After analyzing results of the German 101 exam, results showed that learners from the face-to-face class achieved higher language knowledge in the tested skills writing and reading than the participants who studied with Duolingo for the same period of time. However, no substantial differences were found between groups for the vocabulary and grammar section of the final exam and the Duolingo test. The survey reported that participants who studied with Duolingo all agreed that they liked the experience, especially studying at their own pace. Concerns were also mentioned, however, for example that Duolingo is only good for beginner learners, it doesn’t provide interactions with others, and there is no teacher to ask for explicit feedback.
