The goal of this study was to develop Multinomial Logit models for the mode choice behavior of immigrants, with key focuses on neighborhood effects and behavioral assimilation. The first aspect shows the relationship between social network ties and immigrants chosen mode of transportation, while the second aspect explores the gradual changes toward alternative mode usage with regard to immigrants migrating period in the United States (US). Mode choice models were developed for work, shopping, social, recreational, and other trip purposes to evaluate the impacts of various land use patterns, neighborhood typology, socioeconomic-demographic and immigrant related attributes on individuals travel behavior. Estimated coefficients of mode choice determinants were compared between each alternative mode (i.e., high-occupancy vehicle, public transit, and non-motorized transport) with single-occupant vehicles. The model results revealed the significant influence of neighborhood and land use variables on the usage of alternative modes among immigrants. Incorporating these indicators into the demand forecasting process will provide a better understanding of the diverse travel patterns for the unique composition of population groups in Florida.

In a crescent connected and image-made society in various online social networks, each user taking pictures of him/herself and posting them on social online network, makes a self-registration that emerges in self-representation by aggregated daily practices of various themes. This research aims to study the dynamics of the relations of this photographic self-representation relations with agency, technology, affectivity, and consumption that goes beyond narcissism, composing a being integrated with the visual power and its reverberations, which I hereby call as Being -Image. The goal of this paper is an anthropological look over these practices. In this sense, I carry out the research developed in the field of image and cyber antropology with various interlocutors established in dialogues, analysis and virtual meetings. I tried, besides conversations and interviews, to analyze the profiles on the social network as well as daily posts, photo albums available on online network , sharings and mainly selfies.

This thesis starts from the proposition that postmodernity is the very cultural manifestation of Late Capitalism. The research was concerned with the publication of privacy that gives us news feeds of Facebook online social network. We used netnography, which is considered a construction method in action that combines study skills to immersion of the researcher in the investigated field. Netnography is an alternative methodology for the study of communication threads in cyber environments. We note that there is an exhibition of themselves in a related environment that reproduces the properties of the spectacle society, with an emphasis on the fact that this exhibition be made and want to be made by the individual himself, allegorically, window dresser and with spectacle. The subject is revealed by itself, shown and is induced to show and display at the same time. It is a large-scale exhibition of the private life events; it is more than spectacle, surpassing debordian sense, approaching the exhibitionism in the Freudian sense. It is a subject in a new way of existence. At the time of posting in public, the person violates their privacy. It is the desecration of stardom intimacy. We found that these new behavioral forms sharing of human experiences, under the mediation of typical technologies informationalism era, appear as a major brand of sociability, meshing the ongoing technological revolution.

The use of behavioural indicators of suffering and welfare in captive animals has produced ambiguous results. In comparisons between groups, those in worse condition tend to exhibit increased overall rate of Behaviours Potentially Indicative of Stress (BPIS), but when comparing within groups, individuals differ in their stress coping strategies. This dissertation presents analyses to unravel the Behavioural Profile of a sample of 26 captive capuchin monkeys, of three different species (Sapajus libidinosus, S. flavius and S. xanthosternos), kept in different enclosure types. In total, 147,17 hours of data were collected. We explored four type of analysis: Activity Budgets, Diversity indexes, Markov chains and Sequence analyses, and Social Network Analyses, resulting in nine indexes of behavioural occurrence and organization. In chapter One we explore group differences. Results support predictions of minor sex and species differences and major differences in behavioural profile due to enclosure type: i. individuals in less enriched enclosures exhibited a more diverse BPIS repertoire and a decreased probability of a sequence with six Genus Normative Behaviour; ii. number of most probable behavioural transitions including at least one BPIS was higher in less enriched enclosures; iii. proeminence indexes indicate that BPIS function as dead ends of behavioural sequences, and proeminence of three BPIS (pacing, self-direct, active I) were higher in less enriched enclosures. Overall, these data are not supportive of BPIS as a repetitive pattern, with a mantra-like calming effect. Rather, the picture that emerges is more supportive of BPIS as activities that disrupt organization of behaviours, introducing noise that compromises optimal activity budget. In chapter Two we explored individual differences in stress coping strategies. We classified individuals along six axes of exploratory behaviour. These were only weakly correlated indicating low correlation among behavioural indicators of syndromes. Nevertheless, the results are suggestive of two broad stress coping strategies, similar to the bold/proactive and shy/reactive pattern: more exploratory capuchin monkeys exhibited increased values of proeminence in Pacing, aberrant sexual display and Active 1 BPIS, while less active animals exhibited increased probability in significant sequences involving at least one BPIS, and increased prominence in own stereotypy. Capuchin monkeys are known for their cognitive capacities and behavioural flexibility, therefore, the search for a consistent set of behavioural indictors of welfare and individual differences requires further studies and larger data sets. With this work we aim contributing to design scientifically grounded and statistically correct protocols for collection of behavioural data that permits comparability of results and meta-analyses, from whatever theoretical perspective interpretation it may receive.

The poor performance of students in reading and writing activities, prompted the search for actions that would minimize this problem, noticeable mainly in public education. The lack of interest in reading of poetic texts seen in students from the 7th year in a public school in RN, has led us to question the reasons for the rejection of poetry. Thus, the idea to organize and develop new reading possibilities mediated by digital technologies, considering the preference of teenagers by virtual environments. Therefore, it was essential to observe how students used web resources in order to plan actions that aimed to improve their reading performance. We present to justify the need for reflection on the educational problems starting from our reality, in order to establish appropriate procedures to minimize them. To this end, we draw is to investigate how students appropriated the Facebook social network in order to elaborate reading strategies using this platform. The study is anchored in the reflections of the following theorists and researchers: language concepts and language: Bakhtin (2011 [1979] 2006 [1999]), Bronckart (2012 [1999]), Marcuschi (2008); reading strategies: Leffa (1996) Sol (1998), Antunes (2009), Kleiman (2013); genre: Bakhtin (2011 [1979] 2006 [1999]), Marcuschi (2008); didactic sequence: Dolz, Noverraz and Schneuwly (2013 [2004]); technologies: Moran (2008 [2000]), Kenski (2007), Bento (2012), Behrens (2013); literary literacy: Cosson (2007); other theoretical orientations: PCN (1998), PDE (2008), Perrenoud (1999), among others. The methodology followed action research guidelines, a qualitative approach perspective. The research instruments included questionnaires, interviews, observations and field notes. The results pointed to the interest of students in this social network, which favored the development of a didactic sequence whose activities converged on the didactic use of Facebook as a support for the presentation of textual poetry genre, drawing the attention of students for reading. Thus, we reiterate the need to include the pedagogical use of Information and Communication Digital Technologies educational activities to better meet the expectations of the generation of "digital natives", offering them a significant Portuguese-speaking school that fits your interests.

A expanso das redes sociais virtuais, o aperfeioamento das tcnicas de informao, a penetrabilidade do capitalismo de concorrncia e o fragmentado sujeito ps-moderno constituem, ao lado da sociedade de consumo, os pilares desta tese. Nossa hiptese central que as redes sociais da Internet ampliam os espaos de participao, compartilhamento, colaborao e manifestao das decepes do consumidor, mas no diminuem as descontinuidades, a incompreenso e o desrespeito oriundos das relaes e prticas de consumo, podendo, muitas vezes, aceleraremasconflitualidades. A abertura para o dilogo, o incitamento tomada de poder do sujeito e a multiplicao das trocas entre empresas e consumidores representam a oportunidade e o desafio de valorizarmos a concepo normativa da comunicao, admitindo as dificuldades da intercompreenso, a urgncia da coabitao e a realidade da incomunicao. Recorremos Anlise de Discurso de tradio francesa (AD) como campo terico-metodolgico para analisar o discurso do consumidor inscrito na plataforma Reclame AQUI e construir uma crtica comunicao corporativa contempornea; a partir dos conceitos de cenografia, ethos e esquematizao enunciativa, verificamos como a ideologia opera no interior das cenas daenunciao do consumo, constituindo uma ordem prpria ao discurso do reclamante decepcionado. Esta anlise ratificou as discusses tericas que levamos a cabo, servindo de suporte para a problematizao e o debate das sete cenografias que se evidenciaram no/pelo discurso do sujeito/consumidor: respeito/desrespeito, ameaa, promessa e frustrao, mau atendimento e problema no resolvido, negociao, clientes novos x antigos e consumidor enganado; a imbricao do nosso corpuse o arcabouo terico coloca na ribalta a necessidade de polticas de comunicao organizacional norteadas pelo senso prtico de outridade, transcendendo as relaes puramente mercadolgicas; ao mesmo tempo, lana luz sobre apremncia de mais solidariedade, compaixo, capacidade de escuta, compreenso e coabitao para as corporaes que funcionam em uma sociedade guiada pelo frenesi da tica da concorrncia e da consumolatria. Esta tese evidencia que a atuao dos consumidores e das empresas no mundo on-line representa mais que um elemento circunstancial de (in) tolerncia mtua; desenha um destino comum que pode ter como rumo a outridade solidria do prximo, aceitando a experincia da alteridade, o risco do fracasso e a esperana da confiana e do respeito que a comunicao pode conceber.

Purpose: This paper aims to explore the role of internal and external knowledgebased linkages across the supply chain in achieving better operational performance. It investigates how knowledge is accumulated, shared, and applied to create organization-specific knowledge resources that increase and sustain the organization's competitive advantage. Design/methodology/approach: This paper uses a single case study with multiple, embedded units of analysis, and the social network analysis (SNA) to demonstrate the impact of internal and external knowledge-based linkages across multiple tiers in the supply chain on the organizational operational performance. The focal company of the case study is an Italian manufacturer supplying rubber components to European automotive enterprises. Findings: With the aid of the SNA, the internal knowledge-based linkages can be mapped and visualized. We found that the most central nodes having the most connections with other nodes in the linkages are the most crucial members in terms of knowledge exploration and exploitation within the organization. We also revealed that the effective management of external knowledge-based linkages, such as buyer company, competitors, university, suppliers, and subcontractors, can help improve the operational performance. Research limitations/implications: First, our hypothesis was tested on a single case. The analysis of multiple case studies using SNA would provide a deeper understanding of the relationship between the knowledge-based linkages at all levels of the supply chain and the integration of knowledge. Second, the static nature of knowledge flows was studied in this research. Future research could also consider ongoing monitoring of dynamic linkages and the dynamic characteristic of knowledge flows. Originality/value: To the best of our knowledge, the phrase 'knowledge-based linkages' has not been used in the literature and there is lack of investigation on the relationship between the management of internal and external knowledge-based linkages and the operational performance. To bridge the knowledge gap, this paper will show the importance of understanding the composition and characteristics of knowledge-based linkages and their knowledge nodes. In addition, this paper will show that effective management of knowledge-based linkages leads to the creation of new knowledge and improves organizations' operational performance.

Discussion tools in existing LEs have few or no integrated tools to analyse student learning. This paper proposes tools not only for integrating social network analytics, but also why we need to semantically tag and track key concepts within posts in order to make student learning in discussions visible. This paper will argue for the importance of semantic markup in discussion tools using screenshots of existing LEs and UI mockups of semantically aware discussion tools to argue the case for this element of next generation LEs

Depuis le dbut du XXIe sicle, un type particulier dimages a envahi lespace public constitu par Internet : il sagit des images principales de profil, ces images que les utilisateurs de sites de rseaux sociaux choisissent pour les reprsenter auprs des autres individus connects. Comme le plus souvent il sagit dune image du corps de celui ou celle qui saffiche ainsi, il est intressant de sintresser cette pratique en la rattachant des pratiques plus anciennes. Dans un premier temps, cette tude prsente donc une perspective socio-historique en notant la ressemblance de la pratique de limage principale de profil avec celle de lautoportrait et du portrait command. Cela permet de remarquer plusieurs points de rupture ou dinflexion dans lusage de ce type dimages, mais aussi den dgager les usages sociaux typiques. Ensuite, lobservation dun lieu particulier dInternet permet de tirer les conclusions suivantes : si lusage principal de ces images est facile expliquer, elles servent symboliser une prsence dans des lieux non accessibles aux corps sensibles, ces images montrent toujours des lments qui permettent de dduire une position sociale et elles sont fondamentalement identiques aux images produites avant Internet. Ensuite, ltude de ces images montre quil y a un vritable continuum dans la manire de dvoiler son intimit qui permet daffirmer que la frontire entre public et priv nexiste pas sur Internet. Finalement, ces images montrent une absence de canon quant leur production et une multiplicit des faons de se mettre en scne qui laissent penser quelles sont devenues des symboles part entire dans la communication qui peut stablir entre des trangers sur Internet.

The selected publications are focused on the relations between users, eGames and the educational context, and how they interact together, so that both learning and user performance are improved through feedback provision. A key part of this analysis is the identification of behavioural, anthropological patterns, so that users can be clustered based on their actions, and the steps taken in the system (e.g. social network, online community, or virtual campus). In doing so, we can analyse large data sets of information made by a broad user sample,which will provide more accurate statistical reports and readings. Furthermore, this research is focused on how users can be clustered based on individual and group behaviour, so that a personalized support through feedback is provided, and the personal learning process is improved as well as the group interaction. We take inputs from every person and from the group they belong to, cluster the contributions, find behavioural patterns and provide personalized feedback to the individual and the group, based on personal and group findings. And we do all this in the context of educational games integrated in learning communities and learning management systems. To carry out this research we design a set of research questions along the 10-year published work presented in this thesis. We ask if the users can be clustered together based on the inputs provided by them and their groups; if and how these data are useful to improve the learner performance and the group interaction; if and how feedback becomes a useful tool for such pedagogical goal; if and how eGames become a powerful context to deploy the pedagogical methodology and the various research methods and activities that make use of that feedback to encourage learning and interaction; if and how a game design and a learning design must be defined and implemented to achieve these objectives, and to facilitate the productive authoring and integration of eGames in pedagogical contexts and frameworks. We conclude that educational games are a resourceful tool to provide a user experience towards a better personalized learning performance and an enhance group interaction along the way. To do so, eGames, while integrated in an educational context, must follow a specific set of user and technical requirements, so that the playful context supports the pedagogical model underneath. We also conclude that, while playing, users can be clustered based on their personal behaviour and interaction with others, thanks to the pattern identification. Based on this information, a set of recommendations are provided Digital Anthropology and educational eGames 6 /216 to the user and the group in the form of personalized feedback, timely managed for an optimum impact on learning performance and group interaction level. In this research, Digital Anthropology is introduced as a concept at a late stage to provide a backbone across various academic fields including: Social Science, Cognitive Science, Behavioural Science, Educational games and, of course, Technology-enhance learning. Although just recently described as an evolution of traditional anthropology, this approach to digital behaviour and social structure facilitates the understanding amongst fields and a comprehensive view towards a combined approach. This research takes forward the already existing work and published research onusers and eGames for learning, and turns the focus onto the next step the clustering of users based on their behaviour and offering proper, personalized feedback to the user based on that clustering, rather than just on isolated inputs from every user. Indeed, this pattern recognition in the described context of eGames in educational contexts, and towards the presented aim of personalized counselling to the user and the group through feedback, is something that has not been accomplished before.

This thesis reports on an exploratory study of the relationship between the Internet and womens empowerment in China. The theoretical framework of the study combines feminist theorisations of power the core concept of empowerment with insights from sociological perspectives on power and gender, as well as collective action theory. This allows for the conceptualisation of womens empowerment as a dynamic process that is shaped by a set of communicative practices. Focusing on female Chinese bloggers and womens groups of different organisational types, this study aims to explore the respective ways in which these two types of women actors use the Internet with a view to examining whether, and the extent to which it enables them to generate a sense of empowerment. The empirical data mainly derives from interviews with female bloggers and with staff members from different womens groups, as well as from a features analysis and social network analysis of the sampled blogs and official websites of studied groups. Overall, the findings suggest that the opportunities offered by the Internet for womens empowerment through awareness-raising, social interactions, and the organising of collective action, are limited. For female bloggers, their activities do not translate the new communicative practices afforded by the Internet into concrete action to bring about changes in their everyday life. On the contrary, blogs become an alternative platform to discipline their behaviours and to reinforce patriarchal gendered norms. Moreover, the research finds that the promise of empowerment is further undermined by the pervasive commercialisation of the Internet and state control. For womens groups, contextual factors prevent them from fully realising the potential of the Internet for increasing their organisational visibility, promoting public awareness about gender issues, building a sense of the collective, campaigning, or networking. The major barriers in these processes are state control, a lack of resources, online censorship, and at times, competition from commercial sites. In this respect, the Internet does not play a significant role in forming a collective to challenge existing unjust power relations.

This article examines the use of cinema as a mapping of subjective mutation in the work of Deleuze, Gauttari and Berardi. Drawing on Deleuze's distinction between the reduction of the art-work to the symptom and the idea of art as symptomatology, the article focuses on Berardi's use of cinematic examples, posing the question in each case of to what extent they function as symptomatologies or mere symptoms of cultural and subjective mutations in examples ranging from Bergman's Persona to Van Sant's Elephant to finish on speculations about Fincher's The Social Network as a critical engagement with subjective mutation in the 21st Century.
