Texte intégralRésumé :
Nate con lo scopo di eliminare qualsiasi forma di intermediazione, le valute virtuali, ed in particolare il bitcoin, rappresentano un innovativo sistema di pagamento e si ripromettono di apportare numerosi benefici agli utilizzatori e al sistema economico nel suo insieme. Dall’altro lato, però, date le sue peculiarità di pseudo-anonimato, irrevocabilità e rapidità di trasferimento, possono favorire i fenomeni del riciclaggio e del finanziamento del terrorismo.
Scopo di questa tesi è effettuare un’analisi delle caratteristiche delle criptovalute al fine di evidenziarne le criticità e studiare come la disciplina antiriciclaggio vigente in Italia, attraverso il recepimento delle direttive europee, intenda affrontare tali rischi, utilizzando prevalentemente un approccio di tipo giuridico. Nello specifico, i primi due capitoli si focalizzeranno rispettivamente sullo studio dei bitcoin e sull’evoluzione della disciplina antiriciclaggio nel tempo; il terzo capitolo approfondirà le modalità con cui l’ordinamento italiano ha disciplinato, attraverso il d. lgs. 90/2017, i prestatori di servizi relativi all’utilizzo di valuta virtuale e gli sviluppi futuri.

Texte intégralRésumé :
L’obiettivo di questo scritto è quello di fornire una panoramica sufficientemente chiara che permetta di inquadrare giuridicamente e fiscalmente le sempre più frequenti operazioni effettuate attraverso le valute virtuali.
Fino a qualche anno fa, per esempio, non esisteva alcuna pronuncia ufficiale da parte di uno Stato che rispondesse alla seguente domanda: i Bitcoin, dal punto di vista giuridico, sono una moneta, uno strumento finanziario o un bene immateriale?
Pur trattandosi di un fenomeno in grandissima crescita, infatti, il mondo delle monete virtuali o criptovalute è caratterizzato, a livello normativo, da una serie di profili di incertezza e di lacune che cercheremo di individuare e colmare in questo elaborato.
Nel primo capitolo ci occuperemo di fornire una definizione tecnica di Bitcoin, al fine di capire come funziona questo strumento dal punto di vista informatico e chiarire le idee a coloro che si avvicinino al mondo delle criptovalute per la prima volta.
Proveremo poi, nel secondo, ad individuare il corretto inquadramento giuridico alla luce di quanto visto sulla loro natura tecinca.
Nel terzo capitolo, ci occuperemo dell’analisi sulla sentenza C-264/14 emessa dalla Corte di Giustizia UE, che rappresenta la prima pronuncia ufficiale da parte di un organismo europeo e riguarda il trattamento IVA delle operazioni di cambio valuta in Bitcoin.
Successivamente, nel quarto capitolo, partendo dal contenuto della Risoluzione 72/E — documento attraverso cui l’Agenzia delle Entrate esprime il proprio parere riguardo le imposte dirette nella fattispecie dei cambiavalute monete virtuali/monete tradizionali — analizzeremo il trattamento fiscale delle diverse operazioni aventi come oggetto i Bitcoin nell’ambito delle relative categorie di reddito.
Infine, nel quinto ed ultimo capitolo, parleremo della normativa antiriclaggio nell’ambito delle valute virtuali, soffermandoci su una serie di documenti a livello nazionale ed europeo che hanno cercato di fornire alcune indicazioni sulle operazioni che vengono regolate a mezzo criptovaluta.

Texte intégralRésumé :
Syftet med denna uppsats är att undersöka Bitcoins egenskaper och funktioner samt diskutera dess eventuella påverkan på dagens ekonomiska system. Den forskning som publicerats på ämnet undersöker främst tekniska och säkerhetsmässiga detaljer, det är därför intressant att analysera ur en ekonomisk synvinkel. Genom att använda makroekonomisk teori ska jag försöka klargöra om Bitcoin kan konkurrera med dagens valutor. Bitcoins volatilitet i värde gör det tvivelaktigt, en volatilitet som inte kan kontrolleras. Bitcoin uppfyller delar av de funktioner och egenskaper som definierar en valuta enligt makroekonomisk teori, men inte lika många som fiatpengar och Bitcoin bör därför inte kunna konkurrera med dagens valutor. Fiatpengar är att föredra även i andra områden som acceptans och säkerhet. Bitcoin är bättre ur ett kostnadsperspektiv, dock under specifika omständigheter som sällan uppfylls. Bitcoin kommer därför tills vidare fungera som ett alternativ betalningssystem och valuta för personer och företag som är villiga att ta de risker som medföljer.The aim of this thesis is to investigate Bitcoins attributes and functions and discuss its effect on today’s economic system. The academic work that been published on the subject investigate technical and safety aspects, it is therefore interesting to analyse from a macroeconomic point of view. By using macroeconomic theory I will try to clarify if Bitcoin can compete with today’s currencies. Bitcoins volatility in value makes it doubtful. Bitcoins volatility in value makes it questionable, a volatility that cannot be controlled. Bitcoin meet part of the functions and characteristics that define a currency as macroeconomic theory, but not as many as fiatmoney and should therefore not be able to compete with today's currencies. Fiatmoney is preferable also in other areas such as acceptance and security. Bitcoin is better from a cost perspective, but under specific circumstances that are rarely met. Bitcoin will therefore until further serve as an alternative payment system and currency individuals and companies that are willing to take the risks included.

The topic is explored through literature review on theattributes of virtual reality and sense of place, presented in the theorychapter, and is connected to the empirical research throughout the designprocess chapter. The theories presented strongly indicate that places affecthuman behavior, making them a substantial part of the user experience wheninteracting with designed artifacts in specific locations, which is echoedthough the target audience who voice the need to prototype design conceptsin the context of place. The study culminates in two kinds of virtual realityprototypes, dubbed contextual prototypes, that are suggested to havedifferent use cases depending on what the purpose for prototyping is.

Texte intégralRésumé :
Bakgrund: Riksbanken har haft sedelmonopol sedan 1897, vilket har inneburit att de sedan dess har haft ensamrätt att ge ut pengar. Den teknologiska utvecklingen och den ökade användningen av internet har lett till att virtuella samfund har utvecklats och i vissa fall har dessa samhällen skapat sin egen valuta. Bitcoin är världens första helt decentraliserade valuta och baserades i början av sin existens på teknisk nyfikenhet för en handfull hobbyister. Under de senaste åren har efterfrågan på bitcoins ökat vilket i sin tur har lett till att kursen stigit explosivartat.Syfte: Syftet med uppsatsen är att kartlägga och analysera de transaktionskostnader som kan uppstå när Bitcoin används som betalningsmedel, samt jämföra dessa kostnader med de transaktionskostnader som är förenade med användandet av traditionella betalningsmedel. Genomförande: Studien har genomförts genom en blandning av ett kvalitativt och ett kvantitativt tillvägagångssätt samt genom en bearbetning av transaktionskostnadsteorin inom ramen för ny institutionell teori. Empirin består av tre delar där studien inleds med en litteraturstudie för att läsaren ska få en inblick i vad Bitcoin är och hur valutan fungerar. Därefter presenteras det kvalitativa angreppssättet i form av semistrukturerade intervjuer och avslutningsvis presenteras studiens kvantitativa angreppsätt i form av en enkätstudie för att kartlägga användandet av bitcoin.Slutsats: Studien visar att transaktionskostnaderna för Bitcoin är högre än för traditionella betalningsmedel i och med att valutan i dagsläget är beroende av den traditionella infrastrukturen för betalningar samt att dess användare därutöver frånsäger sig det skyddsnät som traditionella betalningsmedel omfattas av. För att Bitcoin ska bli ett etablerat betalningsmedel krävs det att de grundläggande funktionerna för pengar uppfylls. Något som studien visar är bristfälligt i nulägeBackground: The Swedish central bank has had a currency monopoly since 1897, which has meant that they since then have had exclusive right to issue money. Technological advances and the increasing use of the Internet has led to an evolvement of virtual communities and in some cases these communities created their own currency. Bitcoin is the worlds first fully decentralized currency. In the beginning the currency was based on technological curiosity to a handful of hobbyists. In recent years demand for bitcoins has increased, which has led to a dramatic price increase.Aim: The purpose of this thesis is to identify and analyze the transaction costs that may arise when Bitcoin is used as means of payment, and to compare these costs with the transaction costs associated with the use of traditional means of payment. Completion: The study was conducted through a mixture of qualitative and quantitative approaches as well as a processing of the transaction cost theory in the context of new institutional theory. The empirical material consists of three parts in which the study begins with a literature review for the reader to get a glimpse of what Bitcoin is and how the currency works. The qualitative approach is in the form of semi-structured interviews and finally the study's quantitative approach is presented in the form of a questionnaire to survey the use of bitcoin.Conclusion: The study shows that Bitcoins transaction costs are higher than conventional means of payments when account is taken to the fact that the currency is dependent on the current financial structure. The user furthermore disclaims the safety net that traditional means of payments offer. For Bitcoin to become an established means of payment it requires that the basic functions of money are fulfilled which the study shows is inadequate.

Dixon, Keith. « Being ambidextrous : the value of virtuality in teams ». Thesis, University of Bath, 2007. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.438889.
Texte intégralRésumé :
Team structures and technology-mediated communications have experienced a welldocumented growth in popularity because of their perceived value in delivering productivity. The nexus of these trends, the concept of the "virtual team", might therefore be expected to have clear benefits in comparison to "traditional" teams. However, research has been equivocal in its findings, and in practice "pure" virtual teams, in which members never meet face-to-face, have been rare. Equally, teams that only work face-to-face have become rare, so some researchers have begun to adopt a perspective in which "virtuality" is seen as a characteristic of all teams. Adopting this perspective here, the research reported in this thesis addresses the question of how virtuality in teams contributes to organisational value. Considering teamwork as an intangible asset understood as a form of intellectual capital the research question is posed as: how does virtuality in teams affect the development of intellectual capital? Reviewing the virtual team literature highlights the direction of its development and the gap in understanding that led to the research question. It also provided the roots for the further development of the concept of virtuality in teams. Here it is defined as "virtual continuities" that mediate the effects of discontinuities, such as those created by geography, time, culture, organisations, technology and working practices. Reviewing the literature on intellectual capital, a multi-level model was alsodeveloped in which teamwork was defined as intellectual capital at the team level and comprised of human capital, social capital and structural capital dimensions. Drawing on these two concepts, a team process model and conceptual framework of virtuality were created to provide a focus for the collection and analysis of qualitative data using a case study methodology. The setting for this was an inter-organisational entity, spanning the government, commercial and academic sectors, consisting of teams researching technology and the systems engineering of intelligent systems. The analysis of data from the case study supported the conceptual developments but also pointed to the need to enhance them to capture the importance of discontinuities created by a team's task, membership and temporal boundaries; their effects on the development of intellectual capital; and the role of virtuality in mediating these effects. Returning to the literature, an explanation of the nature of the mediating effect of virtuality on discontinuities was developed using the concept of contextual ambidexterity as the basis for answering the research question.

Texte intégralRésumé :
Governments around the world have pursued ICT based initiatives including the provision of infrastructure to assist regional areas to develop economically (Beckinsale et al. 2006). There has been considerable interest in exploiting ICT to develop high technology clusters and support innovative networks (Lawson & Lorenz 1999). However, these initiatives have met with mixed success. It is clear that such development depends on more than providing appropriate technology Attention to social and organisational factors is crucial if regional areas are to realise the potential of ICT as a tool for regional development (Gengatharen & Standing 2005). It is important to understand the nature of business networking as well as the perspective of those participating in such networks if successful initiatives are to be established. The aim of this research is to identify how ICT can be used for knowledge sharing among businesses in regional areas and how the online networks through which knowledge is shared can contribute to the development of the region.
This research investigates the question of what value small businesses in those regions derive from knowledge sharing networks using ICT. It also seeks to identify the value creation potential of those networks for their region. Previous research has shown that large organisations have achieved significant value from virtual communities of practice (VCoPs) as a structure for sharing knowledge and supporting innovation (Wenger 2004). The concept of Communities of Practice and Virtual Communities of Practice provided a useful point of departure for this research.
The investigation comprised interpretive case studies of two Australian regional areas and their local business networks which incorporated SMEs in a variety of industries. Each case study was conducted in three stages. First, semi-structured interviews were conducted with regional economic development leaders. Second, 192 small and medium business owners were surveyed about their business activities and their participation in local business networks. Third, in-depth interviews were conducted with 23 small business owners to gain a richer understanding of their participation in knowledge-sharing networks and the value they realised or anticipated from various knowledge-sharing activities. A combined analysis of the two cases was conducted as well as the individual analyses. The research adopted a modified Structured Case method (Carroll & Swatman 2000).
The analysis of the two case studies revealed:
a.) There was a significant difference between the majority of SMEs who traded within the region and those trading largely beyond the region. The latters more proactive online sharing knowledge and seeking of business opportunities would enable them to access most value from VCoEs.
b.) The participating SMEs operated in a number of industries and what they had in common was an interest in improving their enterprises. Consequently they used their regional networks which were not aligned to any one industry to make connections and share knowledge. They did not necessarily seek to access specific information.
c.) A necessary prerequisite of VCoEs is having vibrant CoEs where face-to-face interaction enhances the development of trust and social capital. This appeared as an important factor facilitating the move to incorporate online knowledge sharing.
d.) Younger businesses appeared to gain the most value from knowledge sharing in CoEs as they were using their networks to determine how to grow their firm.
e.) The value of VCoEs to the SME participants is primarily in their general connection to other businesses in the region. Since the participants operate in a number of industries, what they have in common is an interest in their enterprises. The main value appears to come from the potential of the VCoEs to add to this connection and to social capital.
This study found that successful management of VCoEs must:
i) Ensure the network website is actively used by members before attempting to incorporate online knowledge sharing.
ii) Monitor and stimulate online forum interaction rather than rely on interaction to occur naturally.
iii) Not rely on email as a mechanism for stimulating knowledge sharing. Email is seen as more appropriate for formal documentation than for candid exchange of views.
The concept of virtual communities of practice was found to be somewhat inappropriate for the diverse SMEs in the regional networks. Because of their diversity, they do not necessarily see value in sharing knowledge about practice but they do see value in sharing more general information and in providing support, connection and ideas that facilitate the strategic direction of their business. To address this issue, the concept of virtual communities of enterprise (VCoEs) is proposed as recognition of what the participating SMEs had in common: an interest in their individual businesses as part of the region.
The original contribution of this research consists of its identification of the issues in linking SMEs across industries. It provides new insights on the business practices of regional SMEs and developed the concepts of Community of Enterprise (CoE) and Virtual Community of Enterprise (VCoE) to capture the special nature of knowledge sharing in regional multi-industry business networks. New perspectives are revealed on the ways that value could be derived from knowledge sharing by these regionally networked SMEs, as such it adds to the body of knowledge in an area where there has been little systematic investigation. This research reinforces the importance of social capital as an essential pre-requisite for accessing the value of intellectual capital in regions. Social capital emerges as vital when establishing and maintaining face-to-face knowledge sharing in regional networks and a necessary pre-condition for successfully establishing online knowledge sharing. Trust is a key factor and this research extends understanding of the role of social capital and the importance of trust in regional networks and online interaction. Its findings have significant implications for the development and management of CoEs and VCoEs as it outlines the key elements that need to be addressed when establishing and maintaining them, the appropriate applications for this context and the issues involved in management of the networking and online contexts. These findings not only increase our understanding of the management dynamics of online networks, they can also provide guidance to those seeking to establish successful VCoEs.

Ziaja, Sonya F. P. « Rules and Values in Virtual Optimization of California Hydropower ». UNIV NEW MEXICO, SCH LAW, 2017. http://hdl.handle.net/10150/625403.
Texte intégralRésumé :
Optimization models for California's hydropower system are designed to be decision-support tools and aids for climate adaptation decision-making. In practice, they fall short of this goal. One potential explanation is that optimization models are not more successful because they are built on, and depend on, a misrepresentation of law and politics. The legal reality of California's hydropower system is a web of networked jurisdictions of multiple federal and state agencies, with varying levels of coordination, long periods of legally obligated stability with rigid rules, and prone to conflict, but with multiple procedures for conflict resolution. Barriers to climate adaptation from that mix vary according to where a given dam is located. The virtual institutional arrangements represented in optimization models are not a simplification of existing arrangements. Instead, they are a dramatic replacement. That replacement is deliberate and reasoned. As seen in two optimization models supported by the state of California, CALVIN and INFORM, the operation of the optimization function of computer models depends on a virtual system of rules that are centrally controlled, coordinated, nimble, and without the possibility of conflict (let alone conflict resolution). But that smooth virtual system comes with a real cost. Institutional economics suggests that this mismatch between existing formal law and represented law may upend the results of models, since value is determined from institutional context.

Texte intégralRésumé :
In this essay results are developed on two different levels. First, it is shown in demonstration that a phenomenological analysis on the lines of Roman’s Ingarden’s study of works in literature can be applied to Virtual Reality works, such as professional-simulators and video-games. In particular it can then be pointed out that: i) sound is separable from the scene, but using sound VR becomes enriched; ii) the main role in literature is left for the imagination, while in VR we find richness in concretization.
Second, it is argued in discussion that works in VR can be qualified as works of art. These electronic works may have all the aesthetical qualities (based on the phenomenology of Roman Ingarden) of the works of art in the traditional sense. So, that paper has two objectives: an analysis of VR and the search for the status of VR in art.

Thesis (MScEng)--University of Stellenbosch, 2002.ENGLISH ABSTRACT: This thesis is about the principles and practices of the emergmg discipline of virtual enterprising within the context of supply chain management. This type of enterprise makes it possible for Southern African companies to compete in the global marketplace against global players. Value chain analysis is firstly discussed to help the business units, within the virtual enterprise, identify their competitive advantage. This competitive advantage will secure the position of these business units within the virtual enterprise. Electronic commerce is described as the vehicle for data communication within the virtual enterprise, and the supported enterprise resource planning (ERP) software as the transaction capturing software. A performance measurement system is proposed that will assist with the management of virtual enterprises at a macro level. Some conclusions and recommendations are made as to how the management of performance can assist the business units, within the virtual enterprise, to grow financially and obtain sustainability. Recommendations are also made for the implementation of the proposed structure within the 3-D Business Simulator.

Texte intégralRésumé :
Contrast Enhanced Spectral Mammography (CESM) and Contrast Enhanced Digital Breast Tomosynthesis (CEDBT) sont des techniques d'imagerie par rayons X à double énergie impliquant l'injection d'un agent de contraste vasculaire. Les deux techniques fournissent des informations sur l'hypervascularisation des lésions par l'absorption de contraste. CESM est une application d'imagerie récemment introduite offrant un meilleur diagnostic du cancer du sein que la mammographie de diagnostique. CEDBT est une technique prometteuse fournissant des informations en trois dimensions, ce qui peut atténuer les limites du CESM. Cependant, sa valeur clinique par rapport à l'examen actuel CESM n'est toujours pas bien comprise. Notre travail vise à évaluer les performance de chaque technique afin de détecter et de caractériser avec précision les différentes absorptions de contraste apparaissant lors des examens cliniques. Cependant, une telle évaluation nécessiterait une vaste base de données de données cliniques avec une représentation complète des divers captages de contraste insérés dans différents contextes hétérogènes, ainsi que la vérité sur le terrain de chaque cas. Au lieu de cela, la nouveauté de notre proposition réside dans l'évaluation des deux techniques à l'aide de données simulées réalistes. Premièrement, nous avons amélioré le réalisme d’un outil de simulation de rayons X analytique. Ensuite, nous avons proposé un nouveau modèle d’absorption de contraste en masse, liée aux lésions mammaires et d’absorption naturelle de contraste de l’anatomie du sein. Enfin, nous avons réalisé un essai clinique virtuel évaluant les performances de détectabilité et de caractérisation du CESM et de la CEDBT à l'aide des outils de simulation développés dans notre travail. Les résultats obtenus montrent que la CEDBT offre une certaine valeur ajoutée clinique par rapport au CESM. En tant que travail futur, les résultats cliniques attendus grâce à la plate-forme de simulation proposée doivent être comparés aux vraies évaluations cliniques lorsqu'un système réel sera disponibleContrast Enhanced Spectral Mammography (CESM) and Contrast Enhanced Digital Breast Tomosynthesis (CEDBT) are dual-energy X-ray imaging techniques involving the injection of a vascular contrast agent. Both techniques provide information on hypervascularization of lesions through contrast uptake. CESM is a recently introduced imaging application providing a better diagnosis of breast cancer than diagnostic mammography. CEDBT is a promising technique providing three-dimensional information, which may alleviate the limitations of CESM. However, its incremented clinical value, compared to the current CESM exam, is still not well understood. This work aims to assess the performance of each technique to detect and accurately characterize the different contrast uptakes appearing in clinical exams. However, such an evaluation would require a large database of clinical data with a complete representation of diverse contrast uptakes. Instead, the novelty of our proposal lies on the evaluation of both techniques using realistic simulated data. First, we improved the realism of an analytic X-ray simulation tool. Then, we proposed a new model for mass-like contrast uptakes related to breast lesions and natural contrast uptake of the breast anatomy. Finally, we performed a Virtual Clinical Trial evaluating the detectability and characterization performance of CESM and CEDBT using the simulations tools developed in our work. The results obtained show that CEDBT offers a certain added clinical value compared to CESM. As a future work, the clinical results anticipated thanks to the proposed simulation platform should be compared to true clinical evaluations when a real system will be available

Wilmott, Deirdre. « What is the value of meaning created through social learning in informal virtual communities ? » Thesis, Federation University Australia, 2016. http://researchonline.federation.edu.au/vital/access/HandleResolver/1959.17/102998.
Texte intégralRésumé :
This study asks the question ‘What is the value of meaning created through social learning in informal virtual communities?’. By researching how people learn in two virtual communities of practice, based around forums, it endeavours to explore learning in online environments that are unconnected to workplace or educational institutions. Both communities studied in this project are meeting places for peers who pursue a domain of personal interest, hence neither community defines itself as a learning environment but as a social meeting place for people to share similar pursuits. The rationale of this study was to explore in-depth the plethora of resources that forum-based communities offer researchers of learning outside the academy, in order to understand the intricacies of un-facilitated social learning. A research strategy for this study was developed from Crotty's (1998) platform which defines: research methods; a methodology; a theoretical perspective; and an epistemology. Triangulated research methods of interview, observation, and personal participation form the basis of data collection. Ethnography, which incorporates auto-ethnography, was the chosen methodology, and the study is centred on a constructivist epistemology. This study employs an interpretivist theoretical perspective, relying on the approaches of two theorists to analyse the data. Both communities were explored by developing four specific propositions from an in-depth analysis of the available literature on informal learning, virtual environments and communities, together with the theoretical understandings of Wenger (1998) regarding Communities of Practice, and Candy (1991) relating to autodidactic and constructed learning. Two viewpoints were chosen because whilst there are a number of theoretical perspectives that can be applied to informal learning in a virtual environment, there is no one agreed theory which comprehensively explains the complexities of individual and social learning in virtual communities. Despite recognition of the Internet as a major source of many people’s informal learning, there is still comparatively limited research undertaken on how this happens. This study is intended to assist in the reduction of this gap by examining aspects of learning including: the connection between autonomous learners and virtual communities; the effect of the written format of the communities observed on dispersing meaning; and the impact of the virtuality of the community on the process of learning and creation of meaning. By undertaking an ethnographical examination of the nature of learning in two informal virtual communities based around written asynchronous forums, this study is intended to contribute to understanding the worth of informal learning in virtual communities where learning occurs between peers. This study contributes to knowledge through its exploration of the way learning occurs in un-facilitated environments and the legitimacy of the outcomes of that learning. Through this exploration, it fosters an appreciation of the value of meaning created in these social environments, as well as their role in validation of communal and individual meaning. It is able to do this by circumnavigating the difficulties earlier researchers have had in developing in-depth studies of the topic because it does not rely implicitly on the perspectives of those participating, or limited-time observations. The study concludes that for both communities their virtuality greatly influences the way their practice develops, as well as how this practice shapes the way in which their members learn in informal environments. It also concludes that learning in these environments is a very complex, often sophisticated, and sometimes contradictory process that is governed by many different, and occasionally competing, aims of individuals and communities. This study also resolved that because of the very complexity of this learning, these two communities produce some very deep and meaningful contributions to their respective domains. As individuals connected within these communities in order to explore their interest in their respective domains, the communities became: repositories of ideas and resources; places to engage in negotiating and renegotiating meaning; and places to validate personal meaning through testing against established community understandings and peer views. Thus after extensive ethnographical research on both communities of this study, it is considered that this work advances the knowledge of learning outside the academy by providing evidence that people do learn effectively in informal virtual communitiesDoctor of Philosophy

Com os atuais cenários, de novos perfis de consumidores e a acelerada evolução tecnológica, as redes sociais virtuais passaram a ser utilizadas como uma importante ferramenta de marketing para geração de valor para o cliente. O presente estudo foi desenvolvido para analisar o papel das redes sociais virtuais na geração de valor para o cliente no segmento de máquinas e equipamentos, aprofundando o conhecimento de como elas contribuem na geração de valor para o cliente. Além de estudar quais ferramentas as empresas estudadas utilizam para sua presença, identificar e descrever como elas avaliam os resultados de suas ações nas redes sociais virtuais e, por fim, identificar lacunas e oportunidades para aprimorarem o uso da ferramenta para criação de valor para o cliente. Esta dissertação é um estudo, em casos múltiplos, no segmento de máquinas e equipamentos, onde a coleta dos dados foi através de entrevista semiestruturada, observação direta e pesquisa documental, cujas unidades de análise foram ThyssenKrupp Elevadores, Marcopolo e Stemac. A partir da revisão teórica do tema, desenvolveu-se a análise dos dados e a construção do relatório final. As empresas utilizam diferentes metodologias e recursos para a gestão das redes sociais virtuais. Visualizaram-se nas três unidades de análise alguns fatores considerados fundamentais, tais como qualidade de serviço, segurança e imagem, além da capacidade de resposta, a qual impacta na satisfação e na qualidade percebida dos clientes. Em todas elas, a permanência e crenças favoráveis do cliente, são consideradas vantagens competitivas e abordadas com relevância. Observou-se que as redes sociais virtuais são um novo modelo estratégico para o marketing das organizações, com alto poder de geração de valor. Porém, elas precisam passar por uma transformação cultural, repensar suas diretrizes e estruturas tecnológicas, além de seus processos operacionais.
Taking into account the current scenarios, the new consumer profiles and the increasingly accelerated technological developments, virtual social networks have played a key role as a marketing tool to generate customer value. The present study was developed to analyze the role virtual social networks play in customer-value generation process within the machinery and equipment industry; thereby deepening knowledge of how they contribute in generation customer value. In addition, it brings a study about what tools such companies use for their presence, identifying and describing how they evaluate the results of their actions in virtual social networks. Finally, the present study identifies gaps and opportunities in order to improve the use of this tool for creating customer value. This dissertation is a study in multiple cases, within the machinery and equipment industry and the data collection was carried out through semi-structured interviews, direct observation and documented research. ThyssenKrupp Elevators, Marcopolo and Stemac were the units of analysis. From the theoretical review, the data analysis was developed and a final report was devised. Companies use different methodologies and resources for the management of virtual social networks. In the three units, key factors, such as service quality, safety and image were perceived, in addition to the response capacity, which impacts on quality and customer satisfaction. In all cases, the customer’s favorable dependability and beliefs, are regarded as competitive advantages and approached with relevance. It was observed that virtual social networks are a new strategic model for marketing organizations, with great potential to create value. Nevertheless, they need to undergo a cultural transformation, rethink their guidelines and technological structures, and operational processes.

Texte intégralRésumé :
The purpose of this study was to examine my own practice of teaching place value and the influence virtual manipulatives had, in addition to physical manipulatives, on place value understanding of my second grade students. I wanted to see how adding a base-ten computer applet might better meet the needs of all learners while also meeting the needs of today's technological classroom. Through this study, I found that both physical and virtual manipulatives helped students acquire place value concepts. I found that virtual manipulatives had features that engaged students in a way that increased their mathematical language, increased students' ability to represent more conceptual understanding of composing and decomposing numbers, and express enthusiasm towards mathematics. A pretest and posttest revealed that students' academic performance increased. While research on virtual manipulatives and mathematical achievement is fairly recent, this study offers insight to other classroom teachers and the research community.ID: 029810048; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (M.Ed.)--University of Central Florida, 2011.; Includes bibliographical references (p. 82-85).

Texte intégralRésumé :
To achieve the highest levels of immersion and presence possible in a Virtual Reality experience, all of the sensory input we receive in the real world must be simulatable in Virtual Environments (VE) as well. Foregoing the more popular audio-visual feedback, this project aims to better understand the benefits of adding tactile feedback (namely that of airflow) to the VR-developer‟s toolkit. Through user tests, involving a hairdryer to produce a strong airflow that is easily redirected and changed in temperature, feedback was collected on the user experiences and applications of airflow in a VE made to simulate a walk through river lands similar to the ones found in Sweden. While there was no singular way that the participants experienced the added sensory input, most reported the airflow as being equally important to feeling immersed as background music, and on average almost as important as other audio cues. Perhaps most importantly, rich insights were gathered that can guide further research.

Texte intégralRésumé :
Management of Collaborative Networked Organizations faces various challenges in terms of decision-making. Particularly, in complex and multi-player environments, like healthcare, it is not easy to find the roots of low performance processes, and unmet goals. This research provides a framework, as well as associated techniques to analyze the value network, identify problematic actors, and consequently, find the best possible solution to change them. The proposed framework consists of two main components: Analyzing the value network, and Multi-Criteria Decision Making. To analyze the value network of a collaborative environment, in addition to the existing techniques, four complementary components are introduced: Actors’ value interchanges matrix, Value Gantt chart, Identifying problematic actors flowchart, and Actors’ ease of substitution table. Employing these hybrid analyses, decision makers gain a better understanding of the bottlenecks in the value network, current conditions and contributions of the involved actors, and the consequences of considering various alternatives. Then, by applying one of the Multi-Criteria Decision Making methods, and based on pre-defined criteria, possible alternatives are analyzed and outlined. As a proof of concept and validation of the proposed methods, we reviewed a scenario of patient flow and wait times in healthcare. We derive the value network for collaborative processes in a hospital, specify the roles’ of actors, identify the bottlenecks, then rank the solutions, and suggest possible changes to improve the performance of the collaborative environment.

Texte intégralRésumé :
Contributors from the mid 20th century up to now have developed and refined virtual assistants, taking the technology from a set of rules to assistants driven by Artificial Intelligence. Today, virtual assistants can provide value in organisation and support a sustainable society by conducting basic and repetitive tasks, and help reduce inequalities caused by biased advisors on sensitive topics. Despite its prosperity, current research somewhat lack focus on the evaluation of virtual assistants in industrial applications. The purpose of this paper is to evaluate virtual assistants from a technical, economical and organisational perspective, in order to understand their performance and value in an industrial environment. This has been done in collaboration with IBM and a client company which prefers to remain anonymous in this report. In this company, two IBM Watson Assistants are under development; one for the IT Service Desk, and one for the Ethics & Compliance department. To cover all aspects of the virtual assistants’ performance, quantitative and qualitative methods were used by conducting user testings and surveys. In this process, discussions have been conducted with IBM experts and employees of the firm for which the practical implementation has been studied, to gain a general and specific understanding from different perspectives. From this paper, the following can be concluded. First, technological performance can be described using quantitative metrics such as coverage, confidence, precision and helpfulness, and should be complemented using qualitative measures such as user satisfaction and perceived user understanding. Second, specific technological performance is relative and the technical limitations as well as it’s maturity should be used as a complement to the evaluation of the assistants. Third, identified organisational benefits include: • reduced time-to-resolution, • reduced handling time, • all-hour-support, • scalability and • user understanding Conclusions specific for the use cases show that an assistant implemented in a narrower use case, that is the Ethics & Compliance assistant, easier can be implemented and performs relatively well also in less developed environments. A broader use case, such as the IT assistant, requires more effort to perform at a high level but may be even more beneficial than in the narrow use case once sufficiently refined.Från mitten av 1900-talet har virtuella assistenter utvecklats och förfinats där teknologin gått från en mängd regler till assistenter drivna av artificiell intelligens. Idag kan virtuella assistenter tillföra värde till organisationer och bidra till ett hållbart samhälle bland annat genom att utföra enkla och återkommande uppgifter samt minska ojämlikheter orsakad av partiska rådgivare i känsliga frågor. Trots framgången har nuvarande forskning inte fokuserat på evalueringen av virtuella assistenter i industriella sammanhang. Syftet med denna rapport är att utvärdera virtuella assistenter från ett tekniskt, ekonomiskt och organisationellt perspektiv för att förstå dess prestation i industriella miljöer. Arbetet har genomförts i samarbete med IBM och en av deras kunder som föredrar att förbli anonyma. I detta företag är två IBM Watson Assistant under utveckling; en för deras IT Service Desk och en för deras avdelning för Ethics & Compliance. I studien har både kvantitativa och kvalitativa metoder använts, däribland användartestning och frågeformulär, för att inkludera alla aspekter av de virtuella assistenternas prestation. I denna process har diskussioner förts med experter inom IBM samt medarbetare på företaget för vilket den praktiska implementationen studerats för att få en förståelse för både generell och specifik kunskap ur olika perspektiv. I denna rapport kan följande slutsatser dras. Ett, den tekniska prestationen kan bestämmas med kvantitativa mätetal så som täckning (coverage), säkerhet (confidence), precision och hjälpsamhet (helpfulness), och kompletteras med kvalitativa mätetal som användarnöjdhet och upplevd förståelse för användaren. Två, specifik teknisk prestation är relativ och de tekniska begränsningarna samt mognad bör användas som komplement till utvärderingen av assistenterna. Tre, identifierade organisationsfördelar inkluderar: • reducerad time-to-resolution, • reducerad hanteringstid, • support ¨öppen dygnet runt, • skalbarhet, och • användarförståelse Slutsatserna i de specifika fallen visar att en virtuell assistent som implementeras inom ett smalare område, som en assistent för Ethics & compliance, enklare kan implementeras samt presterar relativt bra även i en mindre utvecklad miljö. Bredare områden, som en assistent för IT-support, kräver mer arbete för att prestera på en hög nivå men kan vara ännu mer värdefull än assistenten i det smala området när den blivit tillräckligt utvecklad.

Vahtera, Pekka Johannes. « How intra-firm networks create value and liabilities in micro-level processes of global virtual teams ». Thesis, University of Leeds, 2013. http://etheses.whiterose.ac.uk/6509/.
Texte intégralRésumé :
Research on organisational networks is abundant, yet understanding about the positive and negative effects of networks in global business settings remains relatively limited. This dissertation analyses the network mechanisms that add value to global virtual teams (GVTs). More specifically, it examines the role of (i) network structure, (ii) individuals’ network position, and (iii) the types of relationships which people share as both value-adding mechanisms as well as sources of potential liabilities. Added value in this study refers to interpersonal benefits which may help GVTs realise their full potential, meaning an increased knowledge flow, decreased levels of conflict and a higher degree of integration among diverse team members, amongst other things. The theoretical underpinning of this study lies within the intersection of network theory, international business, and virtual team management. The empirical analysis is conducted within a social network data set collected from 160 GVT members from three multinational companies working in a high technology sector. Statistical analyses of these data suggest that network mechanisms such as the types of ties people share (i.e. friendship), reciprocity (i.e. two-way interaction), the structure of ties (i.e. cliques), and an individual’s network positions (i.e. brokerage over structural holes) have important effects on knowledge sharing and potential for conflict. Surprisingly, the GVTs are found to show little tendency for homophily (tendency for similar others) and no support is found for the argument that cultural dissimilarities or geographical distance would negatively affect interpersonal interactions. It is concluded that network-based theories need to be more rigorously tested in global contexts in order to truly evaluate their generalisability for international business.

Thesis, Uppsala universitet, Humanistisk-samhällsvetenskapliga vetenskapsområdet, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-342740.
Texte intégralRésumé :
Under det senaste decenniet har det skett en förändring i Sveriges betalningsmönster där kontanta betalningar nästan helt bytts ut mot elektroniska. I och med denna förändring har Riksbanken påbörjat en utredning om det finns ett behov av en centralbanksutgiven digital valuta, en så kallad e-krona. I denna uppsats analyseras e-kronans förväntade effekter på penningpolitiken och bankväsendet i Sverige. Detta studeras utifrån makroekonomiska teorier samt en kvalitativ undersökning. Studien finner att ett införande av en e-krona utan ränta kan komma att sätta ett zero lower bound på penningpolitiken i Sverige. En räntebärande e-krona kan istället ge Riksbanken möjligheter att utöva en mer kraftfull penningpolitik. Vi finner även att e-kronan kan komma att ses som ett säkert och effektivt betalningsalternativ till dagens betalningsmedel eftersom den vid en utgivning kommer att vara garanterat av Riksbanken. Därmed kan det komma att uppstå en undanträngningseffekt mot de privata bankernas affärsverksamhet vid ett införande av ekronan.

Obanya, Kaycee. « Ascertaining the value of a virtual team strategy in development projects : a synchronicity conceptualization of communication performance ». Thesis, University of Southampton, 2015. https://eprints.soton.ac.uk/400656/.
Texte intégralRésumé :
This research addresses the question of whether or not the adoption of a virtual team strategy creates value throughout the duration of a development project. It looks at the context in which communication occurs, and then examines the practices that are effective in facilitating communication performance. The thesis also presents discussions on the emerging new perspective of media synchronicity and its applicability to the analysis of the Nigerian operations of a development programme. Data collection is centred on Enterprise Resource Planning (ERP) activities. With that in consideration, the research adopts a case study design. The technique of template analysis is applied in the analysis of qualitative data. Three work systems involved in the ERP setting (i.e. Applications Development, Business Services and Infrastructure Support) are examined. Empirical analysis shows that communication media characteristics tend to influence an individual’s behaviour. People also behave differently based on the set of tool, policies and practices open to them – and so virtual teams don't all function in the same way. Research outcomes also contribute to managerial practices: it is suggested that enforcing appropriate control mechanisms can be more beneficial in a virtual team than instilling trust. Socio-emotional functions hold important implications for performance within these environments.

Texte intégralRésumé :
With student attrition in engineering most frequently occurring during the 2nd year due to perceptions of poor teaching and advising, curricular overload, and a lack of a sense of belonging, this study sought to address these concerns in a novel way through videos. This study was inspired by the success of existing on-campus mentoring services that enlist more advanced students to act as academic and cultural mentors, and sought to connect with students who may feel unwelcome or socially inhibited from attending similar services.
On-campus support services have historically experienced service-level concerns with regards to overhead costs that have resulted in targeting specific audiences over restricted durations of time. Through these measures, both lack of awareness and social inhibition to attendance has resulted in some students not receiving the support that they need in order to succeed in engineering. To address this concern, this study developed and tested a video-based intervention on 2nd year students identified as 'at-risk-for-attrition' through GPA and self-reported measures of belonging in engineering. The intervention involved 18 junior- and senior-level engineering students participating in videotaped interviews that were segmented by topic into 305 videos and posted to a private Vimeo channel. These videos acted as static virtual mentors for the study participants.
To evaluate the impact of these videos, an exploratory case study was conducted with 13 'at-risk-for-attrition' participants that included 7 women and 6 men. The participants completed a pre-intervention interview concerning their current status in engineering, a reflection of their first year, and perceptions of on-campus support services. Participants were then asked to watch one hour of videos, keep a notebook of their experience, and record the date and time that each video was watched. Once completed, participants participated in a post-intervention interview concerning their video choices, reactions, and outcomes of the experience, and any affordances that they saw in the intervention tool.
Drawing on expectancy-value theory, the results of this study yielded a model for how participants made their video selections, how they reacted to virtual mentors and interpreted their video content, and how these reactions led to collective identity beliefs and intentions to act on the advice provided. Additionally, participants highlighted some of the affordances of offering mentoring through static videos. Of particular importance was the perception of shared identity between participants and mentors as a precursor to impacting future intentions to act on their advice. The findings led to recommendations regarding the redefinition of desired mentor traits for at-risk-for-attrition students was discovered, and also, the potential for offering virtual mentoring as a proxy or precursor to attending on-campus services without the program- and student-level concerns hindering current offerings.Ph.

Texte intégralRésumé :
Within the realm of applications, a relatively new payment form has emerged: called Microtransactions. These small one-time payments (less than 10 Euros) offer an addendum to an existing app, service, or game. Microtransactions have generated a revenue stream largely due to the tech savvy segment of young adults aged 18 to 24, but there hasn’t been significant research from an academic perspective which sheds light on this trend. This issue prompted the research question: Which quantifiable elements of a Microtransaction contribute to a university student’s purchase decision? The phenomenon of Microtransactions has not previously been studied under traditional theories of consumer behavior, which is what the scope of this research provided. The consumer behavior theories selected include: Ego Depletion Theory, Extended Self, and Perceived Value Theory. The selected methodology was a quantitative survey and content analysis. The data collected partially supported Perceived Value Theory, but was unable to validate Ego Depletion and Extended Self as significant influences on purchasing behaviors of Microtransactions among university students. Although the theories were unable to support all our hypotheses, we still concluded with two major findings. First, pricing and functionality are the primary elements of a Microtransaction which university students will consider before purchasing. Second, the Perceived Value Theory’s consumption values of Emotion and Finance are, indeed, consumption values shared among university students.

Texte intégralRésumé :
In the domain of social design, this thesis introduces a design project that explores a place-centric view on interaction design to address issues of participation, representation, and place. The project aims to envision possible futures of city-scaled digital twins as places that enable collective engagement within communities and between citizens and cities. It explores this aim with a methodology grounded in co-design- and ethnographic values, focusing on the place of Ringön in Gothenburg. The final design outcome of the study is an augmented reality-based application connected to the city-scaled digital twin of Gothenburg. The application introduces a concept that enables citizens to express location-based social and cultural values and engage in common concerns. It enables the City of Gothenburg to communicate with citizens and develop an enriched understanding of the identity and character of places in Gothenburg. The study hopes to contribute with knowledge to the body of work within social design that explores how sustainable smart cities can develop from a bottom-up perspective, in a more participatory and socially sustainable way.

Texte intégralRésumé :
Management of Virtual Organizations faces new challenges that traditional approaches cannot address. This research proposes a performance measurement framework for service oriented virtual organizations including a structural and a procedural component. The structural framework aligns the activities of partners in a virtual organization at three different layers. The first layer is designed for partners’ strategic alignment through coordination of the value creation network. In the second layer, performance dimensions of partners’ collaboration are defined and mapped to the service choreography model. The third layer focuses on assessing effectiveness and efficiency of partners’ domain specific services, which is designed based on ITIL V3 service level management guidelines. In order to consolidate the structural framework, these three layers are integrated using a method for extracting service choreography model and SLA aggregation patterns from the value network. The procedural framework, on the other side, defines the processes required to design the KPI structure, implement the solution, communicate the results, and derive improvements. We propose an implementation architecture that enables inter-organizational performance management in collaborative environments. Then, the IBM products for business process and performance management (IBM BPM, Business Monitor, and Cognos BI) are employed to implement the proposed architecture. The conceptual framework along with the implementation architecture provides an integrated solution for decentralized performance measurement without the need for a central authority. We demonstrate that the proposed solution enhances flexibility, scalability, and interoperability, and supports transparency of partners’ performance information at an agreed-upon level as a basis for mutual trust.

The way companies interact with their consumers has been changing deeply during the last few years. Internet, social networks and new digital marketing features have made it necessary for organizations to adapt themselves to this new context in order to remain market competitive while other companies have already presented new commercial models focused on digital market. Traditional sectors enterprises, such as weddings were also influenced. By means of gathering theoretical background and case studies, this survey has the purpose of analyzing the value creation for a wedding market brand which has been acting exclusively on the internet with the goals of identifying the main strategies and challenges of this sector recently. Drawing on digital marketing and social medias which creates value to the brand, iCasei is nationally known by your wedding webpages evolution in which the focus are improving the website itself as well as the wedding gift lists which can be converted into cash, what, as stated in this survey, makes a great difference due to its reliability and quality known by its consumers and that helps to go over challenges of a totally online services
Nos últimos anos a forma como as empresas se relacionam com o seu consumidor mudaram profundamente. Com o advento da internet, das redes sociais e das novas ferramentas de marketing digital foi necessário que as organizações de adequassem a este novo contexto para se manterem competitivas, enquanto outras empresas já ingressaram em novos formatos e modelos comerciais, visando o mercado digital. Empresas prestadoras de serviço também foram afetadas. Por meio de um levantamento teórico e a aplicação de um estudo de caso, esta pesquisa analisa a criação de valor para empresas prestadoras de serviço que atuam no mercado online, no caso estudado uma marca do mercado de casamentos que atua única e exclusivamente na internet, tendo como objetivo identificar as principais estratégias e desafios deste setor no atual cenário. Assim como se dá a utilização de ferramentas de marketing digital e redes sociais para criar valor à marca, neste caso estudado, uma das maiores empresas brasileiras de casamento na internet, o iCasei, conhecido nacionalmente pelo desenvolvimento de sites de casamentos e listas de presentes convertidas em dinheiro, que, como constatado neste estudo, possui seu grande diferencial no que diz respeito à qualidade e credibilidade percebida pelos seus consumidores e que ajudam a superar os desafios de uma prestação de serviço totalmente online

This thesis aimed at investigating the social and affective correlates of romantic relationships. It has emphasis on virtual infidelity. This study was theoretically and methodologically carried out by using the theoretical contributions of tetrangular model of love and human values. It also counted on the studies about romantic jealousy and the addiction to the Internet. In order to achieve the aim of this thesis it was necessary to develop three studies: the first characterized as preliminary and instrumental was aimed at adapting/validating two instruments; the virtual infidelity scale and the Internet addiction scale for the Brazilian context. The participants were 246 college students from public and private educational institutions of João Pessoa, PB; with age range of 17-55 years old (mean = 24.3, SD = 7.15), most of them were female (62.1%). The results obtained by the Exploratory Factor Analysis of the virtual infidelity scale revealed two dimensional structures: sexual relationship (α = 0.96) and friendship relationship (α = 0.81). The results of the measurement addiction to the Internet indicated a one-dimensional structure (α = 0.89). The Study 2 was aimed at confirming the factor structure of the scales applied in the first study and verify the strength of correlations with the constructs love, jealousy and human values. A number of 210 university students were the participants who answered the same scales from Study 1, added to the measures: tetrangular love, romantic jealousy and the questionnaire of the basic values. These participants ages ranged from 17 to 50 years (M = 23.6, SD = 6.41) mostly were female (73.8%). The results obtained by the Confirmatory Factor Analysis (CFA) of virtual infidelity and addiction to the Internet for the Brazilian context suggested that the model with four and three dimensions, respectively which was originally proposed by the authors, was the one that best showed adequated validity and accuracy (GFI = 0.89, CFI = 0.97 and GFI = 0.83, CFI = 0.96). Concerning the predictive strength of the measures: addiction to Internet, jealousy, love and human values it was observed that the first variable contributed significantly to the explanation of the attitudes towards virtual infidelity (R = 0.25, p <0.001), the second variable romantic jealousy showed a marginal contribution (R = 0.30, p = 0.05), the third independent variable, love, did not have a significant contribution (R = 0.34, p> 0.05), and, lastly, the human values had a prominent contribution (R = 0.49, p <0.001).The third study aimed to developing a theoretical model to explain the constructs based on the human values, jealousy and addiction to the Internet was carried out to explain attitudes towards virtual infidelity. The participants were 204 Internet users, with age range of 17 to 66 years (M = 29.3, SD = 10.34), mostly female (59.8%). The results of the statistical analyzes indicated that the three constructs were fundamental for explaining the attitudes toward virtual infidelity. Concerning the human values (r = -0.15, p <0.05) the results brought out the sub functions experimentation, suprapersonal, existence, normative and realization, the romantic jealousy (r = -0.33, p <0.001) with dimensions not threatening,, exclusion and addiction to Internet (r = 0.13, p <0.05) with dimensions withdrawal and social problems, time management and performance and replaced reality were underlying components facing the attitudes toward virtual infidelity. Based on these findings it may be inferred that the results contributed satisfactorily with the explanatory model of behavior about the virtual infidelity. It is also expected that these results may be applied in future researches.
Esta tese teve como objetivo geral conhecer os correlatos afetivos e sociais dos relacionamentos amorosos com ênfase na infidelidade virtual. Para subsidiar teórica e metodologicamente, utilizaram-se dos aportes teóricos do amor tetrangular e valores humanos, adicionado aos estudos acerca do ciúme romântico e da adição à Internet. Para alcançar o objetivo, fez-se necessário desenvolver três estudos: o primeiro com caráter preliminar e instrumental visando adaptar/validar dois instrumentos, a escala de infidelidade virtual e a escala de adição à Internet para o contexto brasileiro. Participaram 246 estudantes universitários de Instituições Pública e Privada da cidade de João Pessoa (PB), com idade variando de 17 a 55 anos (m = 24,3; dp = 7,15), a maioria (62,1%) do sexo feminino. Os resultados advindos da Análise Fatorial Exploratória da escala de infidelidade virtual evidenciaram uma estrutura bidimensional: relação sexual (α = 0,96) e relação de amizade (α = 0,81). Os resultados da medida de adição à Internet indicaram uma estrutura unidimensional (α = 0,89). O Estudo 2 teve como objetivo confirmar a estrutura fatorial das escalas do primeiro estudo e verificar qual o poder de correlação com os construtos amor, ciúme e valores humanos. Fizeram parte 210 estudantes universitários que responderam as mesmas escalas do Estudo 1 acrescidas das medidas: amor tetrangular, ciúme romântico e o questionário dos valores básicos, as idades dos participantes variaram entre 17 a 50 anos (m = 23,6; dp = 6,41), a maioria do sexo feminino (73,8%). Os resultados advindos da Análise Fatorial Confirmatória (AFC) das medidas de infidelidade virtual e adição à Internet para o contexto brasileiro sugerem que o modelo originalmente proposto pelos autores, com quatro e três dimensões, respectivamente foi o que melhor apresentou parâmetros de validade e precisão adequados (GFI = 0,89, CFI = 0,97 e GFI = 0,83, CFI = 0,96). Quanto ao poder de predição das medidas adição à Internet, ciúme, amor e valores humanos observou-se que a primeira variável contribuiu significativamente para a explicação das atitudes frente à infidelidade virtual (R = 0,25, p < 0,001); a segunda variável o ciúme romântico apresentou uma contribuição marginal (R = 0,30, p = 0,05); a terceira variável independente, o amor, não teve uma contribuição significativa (R = 0,34, p > 0,05); e, por fim, os valores humanos tiveram uma contribuição de destaque (R = 0,49, p < 0,001). O estudo 3 teve como objetivo elaborar um modelo teórico explicativo a partir dos construtos valores humano, ciúme e adição à Internet para explicar as atitudes frente à infidelidade virtual. Participaram 204 usuários da Internet, com idade variando entre 17 a 66 anos (m = 29,3; dp = 10,34), sendo a maioria do sexo feminino (59,8%). Os resultados advindos das análises estatísticas mostraram que os três construtos foram determinantes para explicar a atitude de infidelidade virtual. Na medida dos valores humanos (r = -0,15; p < 0,05) sobressaíram as subfunções experimentação, suprapessoal, existência, normativa e realização, o ciúme romântico (r = -0,33; p < 0,001) com as dimensões não-ameaça e exclusão e adição à Internet (r = 0,13; p < 0,05) com as dimensões retirada e problemas sociais, gestão do tempo e desempenho e realidade substituída foram subjacentes às atitudes frente a infidelidade virtual. Em síntese, pode-se inferir que os resultados contribuíram de maneira satisfatória com o modelo explicativo do comportamento acerca da infidelidade virtual. Espera-se também que estes resultados possam ser aplicados em pesquisas futuras.

Texte intégralRésumé :
When developing the driver interface in their trucks, Scania is highly concerned with creating a certain feeling. When pressing a push-button this Scania feeling shall be perceived. It is not obvious what the Scania feeling really is and there is no predefined method to create it. This Master Thesis takes aim at providing the means to improve the process of creating this feeling.
First, the Scania feeling was studied via the results of an already made survey at Scania. This survey focused on subjective properties of push-buttons, rotary knobs and levers and related the properties to whether these objects had a Scania feeling or not. This existing data was analyzed statistically. The main task of this Master Thesis, however, was to create an environment where the feeling of a push-button could be tried out and described. This environment was created with a tool from Reachin Technologies AB. The environment is a virtual representation of a push-button module, created with computer haptics and graphics. The environment lets the user interact with a three dimensional view collocated with a force feedback device. The force feedback device lets the user feel what is seen through a pen like interface. The “tip” of the pen is used to touch what is seen in the 3D view. The virtual push-buttons was built from blueprints of real push-buttons to be able to evaluate to what extent the virtual buttons resembled the real ones.
The statistical analysis made in this project does not support the notion of describing the Scania feeling with a set of subjective values. The virtual environment created proved to be very life like. The real push-button feeling could be recreated with high precision. When evaluated, the majority of test persons argued that it could be used in the development process.

Texte intégralRésumé :
E-commerce and transactions in virtual worlds has monetary value and may lead to actual cash flows. Where real money trade occurs tax authorities are bound to seek ways and means in which to levy and collect taxes (Pienaar, 2008:38). Previous research on the application of the South African income tax laws to transactions in virtual worlds has been conducted. The application of the charging section of the value added tax laws in South Africa has also been researched in the context of e-commerce and transactions in virtual worlds. Limited research has been conducted on the actual value added tax collection methods in the context of e-commerce and transactions in virtual worlds. This study critically analyses the value added tax collection methods employed in South Africa in the context of ecommerce and transactions in virtual worlds and compares the extent of its application to the extent of the goods and services tax collection methods’ application employed in Australia in this context. The study concludes that that the value added tax collection methods employed in South Africa and the goods and services tax collection methods employed in Australia are similar. Special rules have been adopted in Australia to ensure goods and service taxes are collected on the supply electronic goods. This is not the case in South Africa. However, in the case of transactions in virtual worlds, both countries’ collection methods struggle in ensuring value added tax and goods and service taxes is collected where the supplier of a virtual item is foreign in relation to South Africa or Australia. AFRIKAANS : E-commerce en transaksies in virtuele wêrelde het monetêre waarde en mag in sekere omstandighede kontantvloeie tot gevolg bring. Wanneer regte geld verhandel word sal belasting owerhede altyd maniere soek om belasting the hef op die onderliggende transaksies en dit in te vorder (Pienaar, 2008:38). Vorige navorsing rakende die toepassing van die Suid Afrikaanse inkomste belasting wetgewing in virtuele wêrelde is al voorheen gedoen. The toepassing van die heffings artikel in the belasting op toegevoegde waarde (BTW) wetgewing op e-commerce en transaksies in virtuele wêrelde was ook al vorheen nagevors. Min navorsing was gevind wat aleenlik fokus op die invorderings meganismes in die BTW wetgewing in die konteks van transaksies in virtuele wêrelde en e-commerce. Hierdie studie analiseer krities die toepassing van die invorderings meganismes in die Suid Afrikaanse BTW wetgewing in die konteks van e-commerce en transaksies in virtuele wêrelde en vergelyk die toepassing daarvan met die toepassing van die Australiaanse goods and services tax wetgewing se invorderings meganismes in dieselfde konteks. Die studie lig uit dat die twee lande se invorderings meganismes baie dieselfde is. The Australiaanse wetgewing maak egter spesiale voorsiening vir lewerings met betrekking tot e-commerce. Dit is nie die geval in Suid Afrika nie. Met betrekking tot transaksies in virtuele wêrelde sukkel beide lande se invorerings meganismes om seker maak dat BTW en goods and services tax ingevorder word waar die verskaffer nie Suid Afrikaans of Australiaans is nie.Dissertation (MCom)--University of Pretoria, 2012.

Denna artikel undersöker hur förväntningarna hos spelaren inför en upplevelse påverkar dennes subjektiva upplevelse med ett verk. Genom självutvärdering från spelare påvisar undersökningen kopplingen mellan förväntningar och upplevd upplevelse genom den tillhörande gestaltnings designkontext. Denna undersökning ämnar försöka ge en definition på termen “spelarens förväntningar”, samt hur denna term kan användas i spelskapande som ett verktyg för att uppnå förståelse för spelaren. Detta genom ett fokus på de subjektiva politiska-, etiska- och kulturella värderingarna hos spelaren.This article investigates how expectations among players before an interaction with a game design could influence the subjective experience. This article shows the influence a player’s expectation has on the subjective experience with a specific design context through the prototype accompanied by this paper. This investigation aims to give the term “Player’s Expectation” a definition, as well as a demonstration of using said term with the goal of understanding the individual player. While simultaneously focusing on the player’s political-, ethical- and cultural values.

Evolução tecnológica, uso de "robôs" nos atendimentos, consumidores mais exigentes, ativos e com comportamentos mais complexos e difíceis de serem previstos, enxergar o consumidor além de um mero receptor passivo, são alguns dos desafios a serem enfrentados pelas organizações. Compreender os motivadores comportamentais dos consumidores é fator imprescindível para a competitividade de um negócio. Este trabalho buscou analisar a intenção de uso da tecnologia de atendimento autônomo e a disposição do consumidor em cocriar quando no uso dos serviços prestados por um Agente Virtual de Atendimento (AVA), tendo por mediadores do processo, no modelo proposto, a percepção de utilidade, facilidade de uso e atitude. Como antecedentes, no modelo construído com base na revisão da literatura, seis foram propostos (Normas Subjetivas, Necessidade de Interação, Experiência, Auto-eficácia, Controle e Ansiedade). O método utilizado neste trabalho é o quantitativo com uma abordagem conclusiva descritiva que utilizou um levantamento com 943 respondentes de todo o Brasil, com idades entre 15 e 65 anos, a partir de uma survey com escala intervalar de sete pontos. A análise dos resultados foi feita com base em estatísticas multivariadas, utilizando-se como método de análise a Modelagem de Equações Estruturais no intuito de testar o modelo, investigar e analisar os elementos propostos e suas relações. O trabalho apresentou 18 hipóteses das quais 12 apresentaram-se significantes e 6 não apresentaram níveis de significância adequados. Como resultado mais relevante encontrou-se um forte caminho que propõe uma influência significante e positiva da facilidade de uso sobre a utilidade (sig<0,001 e β = 0,543), utilidade influenciando a atitude (sig<0,001 e β = 0,745), atitude impactando positivamente a intenção de uso (sig<0,001 e β = 0,917) e intenção de uso influenciando positivamente a disposição para cocriar (sig<0,001 e β = 0,656). Esta pesquisa demonstrou que o consumidor percebe-se inserido no processo de cocriação e encontra valor nesta relação, mesmo quando no uso de serviços prestados por Agentes Virtuais de Atendimento. Demonstrou também que um Agente Virtual de Atendimento pode ser uma boa solução na prestação de serviços uma vez que seja útil e eficaz do ponto de vista dos consumidores.
Technological evolution, the use of "robots" in the services, more demanding consumers, more active and with more complex behaviors and difficult to be foreseen, to see the consumer as well as a mere passive receiver are some of the challenges to be faced by the organizations. Understanding the behavioral motivators of consumers is an essential factor for the competitiveness of a business. This work sought to analyze the intention to use the technology of autonomous service and the willingness of the consumer to co-create when using the services provided by a Virtual Attendance Agent (AVA), having as mediators of the process, in the proposed model, the perception of utility , ease of use and attitude. As background, in the model built on the literature review, six were proposed (Subjective Norms, Need for Interaction, Experience, Self-efficacy, Control and Anxiety). The method used in this work is the quantitative one with a conclusive descriptive approach that used a survey with 943 respondents from all over Brazil, aged between 15 and 65 years, from a survey with an interval of seven points. The analysis of the results was made based on multivariate statistics, using as a method of analysis the Modeling of Structural Equations in order to test the model, investigate and analyze the proposed elements and their relationships. The study presented 18 hypotheses of which 12 were significant and 6 did not present adequate levels of significance. As a more relevant result, we found a strong path that proposes a significant and positive influence of ease of use on utility (sig <0.001 and β = 0.543), utility influencing attitude (sig <0.001 and β = 0.745), attitude impacting positively the intention to use (sig <0.001 and β = 0.917) and intention of use positively influencing the willingness to co-create (sig <0.001 and β = 0.656). This research demonstrated that the consumer perceives himself inserted in the process of co-creation and finds value in this relation, even when in the use of services provided by Virtual Agents of Attendance. It has also demonstrated that a Virtual Attendance Agent can be a good service delivery solution as it is useful and effective from the point of view of consumers.

Texte intégralRésumé :
The increased interest in relationship marketing and the potential of the Internet as a platform for relationship building activities have given rise to new ways for companies to interact with their customers, such as services based on a freemium pricing model. Based on the premise that relationships are processes consisting of interactive moments of value-creating activities, value is considered subjective, relative and dependent on the context in which the activity takes place. Value is therefore variable given its context and cannot be pre-defined without nuances being lost. Despite the Internet's given role in societal development, our understanding of what contributes to customers' intentions to build relationships with online services is yet to mature. As the music industry is well established on the Internet, alongside the change in how music is consumed, it is thus appropriate to examine activities in accordance with a freemium based service that distributes music online, since it still lacks in academic understanding. This study aims to provide insights about virtual relations and how online services that provide cultural content should relate to there users as well as contributing to the ongoing academic discussion regarding value and how it is manifested by highlighting contextual impact on relational activities. For a rapprochement of relations to online services in cultural industries, this study assumed a practice perspective. In accordance with practice theory and action research, primary data was collected through participatory observation set in users' natural social environment, with a targeted sample of informants well familiar with the object of study - the online service Spotify. The results show that value in virtual relationships arise inter-subjectively between users, where value is relative to past experiences, changeable over time, and expressed through individual and collective activities afforded by current context. If usage of a service is part of the daily routine, it also becomes a part of the user's identity, which the user, in order not to disrupt the routine, is willing to make sacrifices to uphold, thus maintaining their identity and ongoing relationship to the service provider. The more affordances a service provider manages to convey, the more meaningful a relationship is considered to be. The affective dimension of cultural products, especially music, allows for interpersonal coordination, and emotional convergence, where value is created inter-subjectively through collectively shared practices, allowing us to share feelings and experiences and enjoying how the closeness of interpersonal relationships contribute to our everyday lives. The inter-subjective value creation process thus also works as a process of humanizing the virtual relationship.Det ökade intresset för relationsmarknadsföring och Internets potential som plattform för relationsbyggande aktiviteter har gett upphov till nya sätt för företag att interagera med sina kunder, till exempel genom freemium-tjänster. Utifrån premisserna att relationen är en process av interaktionsögonblick av meningsskapande aktiviteter, förutsätts värde vara subjektivt, relativt och beroende av kontexten i vilken aktiviteten utspelas. Värde är således föränderligt givet kontexten och kan inte på förhand definieras utan att nyanser går förlorade. Trots Internets givna roll i samhällsutvecklingen, saknas fortfarande förståelse för vilka parametrar som bidrar till kunders intentioner att bygga relationer med online-tjänster. Då musikindustrin är väl etablerad på Internet, parallellt med att det skett en förändring av hur musik konsumeras, är det således motiverat att undersöka aktiviteter förenliga med en tjänst som distribuerar musik online, baserad på affärsmodellen freemium, då den akademiskt sätt ännu befinner sig i sin vagga. Studiens syfte är att ge insikter om virtuella relationer för hur online-tjänster med kulturellt innehåll ska förhålla sig till sina användare och bidra till den pågående akademiska diskussionen om hur värde manifesteras genom att belysa kontexters inverkan på relationer. För ett närmande av relationer till online-tjänster inom kulturella industrier, antogs för denna studie ett praktikperspektiv. I enlighet med aktionsforskning inhämtades primärdata genom deltagande observation i användarnas naturliga sociala miljö, baserat på ett målinriktat urval av informanter väl bekanta med studieobjektet - online-tjänsten Spotify. Resultatet visar på att värde inom virtuella relationer uppstår intersubjektivt mellan användare, är relativt mot tidigare erfarenheter, är föränderligt över tid, och kommer till uttryck genom individuella som kollektiva aktiviteter beroende av rådande kontext. Är användningen av tjänsten en del av den dagliga rutinen, blir användningen en del av användarens identitet, med påföljden att användaren är beredd att göra uppoffringar för att inte bryta rutinen och på så vis upprätthålla sin identitet och relation till tjänsten. Ju fler affordanser tjänster lyckas förmedla, desto mer meningsfull upplevs relationen. Den affektiva dimensionen som kulturella produkter för med sig, särskilt musik, möjliggör för interpersonal koordination och emotionell sammanstrålning, där intersubjektivt värdeskapande kollektivt tillskjuter värde i den gemensamma upplevelsen, då vi tillåter oss att dela våra känslor och upplevelser och njuta av den närhet som mänskliga relationer bidrar till i våra vardagliga liv. Det intersubjektiva värdeskapandet bidrar till ett förmänskligande av den virtuella relationen.

With network technology is coming of age, we are in a complex network of entities and virtual coexistence, which not only completely changes the industrial structure, but also allows people to freely shuttle between physical and new networks, resulting in multiple personal or organizational identities. In the global supply chain network formed by virtual - physical social networks, individuals or organizations can cooperate with others flexibly, thereby the value creation strategy oriented by social capital cannot be ignored. Previously, scholars’ discussion relatively focus on the impact of social capital of entity or virtual network on value creation from the perspective of network relationship structure. Furthermore, the research as to the network context of virtual and physical coexistence is still limited the conceptual framework, and the specific conceptual framework and analytical methods are still ambiguity. This study utilizes multiple embedded cases study for exploratory research, based on social capital, value activities and value creation and other related theories, and to light up four platform ecology cases, The Light up of Dadaocheng platform, Pinkoi cross-border e-commerce design, Shop.com and E.SUN BANK financial service, representing different growth stages. Through interviews and comparative analysis of participatory observation, this paper attempts to clarify the similarities and differences between Virtual - Physical social capital from different growth stages of platform ecology. Therefore, in terms of measurement indicators, the study divides social capital into four categories, virtual, physical, homogeneity and heterogeneous which constitutes a 2*2 Matrix. Furthermore, the study subdivides the categories of social capital from the knowledge, information, brand, goods and access of key network resources in business model. For the sake of exploration how social capital creates value, this study divides value activities into four categories，complementarity value activities, diminishes value activities, supplementary value activities and transformation value activities. Meanwhile value creation is divided into three stages, value formation, value sharing and social well-being. Research findings. Firstly, in the platform ecological network, participants can measure their network position in the platform ecosystem through the key network resources and cooperative relationships among participants. Therefore, this study proposes a new theoretical view of the key resource centrality. Secondly, the interactive impact of different key network resources on value creation. Thirdly, the different growth stages of platform ecology affect the priority of value creation. Fourthly, four different value activities, complementarity, diminishes, supplementary and transformation, affect the creation of value by social capital. Finally, based on the theoretical framework and case analysis results, this study puts forward the contribution of this study to the theory, management implications, and suggestions for future follow-up research.

Texte intégralRésumé :
In recent years, the e-commerce sector across industries has grown rapidly, with the e-grocery market yet to produce any clear winners. This was mainly due to high customer expectations and substantial commercial difficulties, making it very complicated to profitably serve the market. With the ongoing Covid-19 pandemic, the e-grocery field has experienced particular attention and growth. The UK’s Ocado is regarded as an exception in the e-grocery sector due to its pioneering position in robotic automation and Artificial Intelligence (AI), its ongoing transformation to a global solutions business as well as extraordinary share performance, recently making it the most valuable grocer in the UK. To identify distinctive components of e-groceries along the value chain, customer expectations were discovered through surveys, after which commercial difficulties were identified using expert interviews. Further, the Ocado model was analyzed, which allowed to illustrate how it addresses expectations and difficulties by leveraging the virtual value chain (VVC). It became clear that Ocado achieves cost-decreasing and differentiation advantages by building a value matrix, enabling it to profitably serve the market. The study therefore lays out that virtual value creation is becoming an increasingly important component in grocery retailing. Subsequently, scenarios for uptake of VVC adoption among stakeholders in the retail sector were created. The outcome suggests that a business-as-usual scenario in VVC uptake is most likely. In this case, firms will ramp up their IT operating budgets by 2-5% p.a., responding to new realities in both physical and online retailNos últimos anos, o setor de comércio eletrónico cresceu rapidamente, embora a e-grocery ainda não tenha evidenciado nenhum vencedor claro. Isto deve-se maioritariamente às altas expectativas dos clientes aliadas a dificuldades comerciais, tornando complicado atender o mercado de forma lucrativa. Com o desenrolar da Covid 19, o setor de e-grocery tem recebido particular atenção e evidenciado crescimento. A Ocado UK é considerada excecional na indústria de comércio eletrónico devido à sua posição pioneira em automação robótica e inteligência artificial (IA) e pela sua contínua transformação num negócio de soluções globais, tornando-a recentemente a mercearia mais valiosa do Reino Unido. De forma a identificar os distintos componentes de e-grocery na sua cadeia de valor, as expectativas dos clientes foram primeiro determinadas através de inquéritos, sendo posteriormente identificadas possíveis dificuldades comerciais através de entrevistas com especialistas. Além disso, o modelo Ocado foi analisado, com um foco na forma como aborda as expectativas e dificuldades de utilização da cadeia de valor virtual (VVC). Como resultado, o estudo conclui que a criação de valor virtual se está a tornar um componente cada vez mais importante na comercialização de alimentos, sendo então gerados cenários para a aceitação do uso do VVC pelas partes interessadas no setor. O resultado indica que o mais provável é um cenário de adoção na lógica de negócios como o habitual. Neste caso, as empresas aumentarão os seus orçamentos operacionais de TI em 2 a 5% ao ano, em resposta às novas realidades.

With the emerging of social network websites, more and more social network online games are produced. Also, the trend of playing online games with friends encourages the flourishing VWs market. Nowadays, users own more selections of VWs games while companies consequently suffer from the problems of high customer turnover rate and low-customer-loyalty. Moreover, according to the Pareto principle, 80% of a company's profits come from 20% of its customers (the high value segment). Losing a high-value customer will naturally be more damaging than the loss of a low-value one. Therefore, building a churn prediction model to facilitate subsequent churn management and customer retention is the best core marketing strategy. In this paper, we put emphasis on modeling a hybrid classification, which takes monetary cost, user behavior and social neighbor features into consideration. Through the perspective of RFM model, we can predict more precisely. Our research applies the dataset from Roomi and several common classification methods to conduct the prediction. The experimental results show that the proposed hybrid model is more thoughtful and well-suited for this problem compare to the traditional way in each classification method.
