Adapting E–Commerce Success Factors to Service-Oriented E–Business : A Comparative Analysis

Guzman Bacarreza, Victor, Al-Hakimi, Mazen January 2024 (has links)
This thesis explores the potential for integrating established e-commerce success factors (ECSF) into service-oriented e-business (SOEB). It examines whether traditional e-commerce principles can be adapted to SOEB practices. The research follows a dual-path approach, analyzing the SOEB literature and comparing empirical data from SOEB practices with this literature, as well as conducting a parallel comparative analysis of ECSF to determine which factors are relevant in the context of SOEB. Our findings reveal that while ECSF cannot be directly replicated in SOEB due to different operational contexts, many ECSF are naturally aligned with SOEB domain needs, but require contextual adaptation. Key success factors such as customer relationship management & customer support, personalized service delivery, platform usability, and robust security measures are important for both domains. The study also highlights the growing importance of servitization and social sustainability in SOEB, reflecting a shift in consumer values toward more socially responsible business practices. A theoretical model was developed to illustrate the transferability of ECSF to SOEB. This model distinguishes foundational factors already integrated to SOEB and identifies new factors for future exploration. It serves as a practical framework for industry practitioners seeking to extend SOEB operations through the use of e-commerce strategies. The research contributes to the academic discussion by bridging the unexplored gap between e-commerce and SOEB literature and presents an approach to incorporate ECSF to SOEB contexts. Future research directions include empirically testing the theoretical model, exploring additional e-commerce success factors, and investigating the role of emerging technologies and social sustainability in SOEB.

Från skroll till klick: Nycklarna till effektiva Instagram-annonser för unga vuxna med tekniskt intresse / From scroll to click: The keys to effective Instagram ads for young adults with a tech interest

Flodin Jakobsson, Sarah, Lindblom, Clara January 2024 (has links)
Denna studie undersöker effekten av designelement samt strategier och dess påverkan av klickfrekvensen (CTR) på Instagram bland unga vuxna med ett intresse för teknik. Genom att använda både kvantitativa enkäter och kvalitativa fokusgrupper, baserade på tidigare forskning och teori inom digital marknadsföring, klickfrekvens, personanpassning, designelement samt strategier, syftar studien till att identifiera vilka designelement och strategier som kan öka användarens engagemang och därmed klickfrekvensen. Resultaten från studien bekräftar att annonser som är noggrant anpassade med fokus på visuella och interaktiva element som färgsättning, layout, text och dynamiskt innehåll, i betydande grad förbättrar användarinteraktionen. Även om studien bekräftar att välutformade, personanpassade annonser är kritiska för framgångsrik digital marknadsföring riktad mot unga vuxna med tekniskt intresse, lyfter den även fram hur avgörande noggrann analys av användardata och beteendemönster är för att optimera annonsernas effektivitet. Slutsatsen drar att personanpassade och visuellt tilltalande Instagram-annonser spelar en avgörande roll i att locka och engagera denna målgrupp trots deras begränsning. / This study looks at how elements of design and strategies affect the click-through rate (CTR) on Instagram for young adults interested in technology. Using both quantitative surveys and qualitative focus groups, based on previous research in digital marketing, click-through rates, personalization, strategies and design elements, the aim is to find out which strategies and design elements increase user engagement and click-through rates. The results show that ads tailored with visual and interactive features like color schemes, layout, text, and dynamic content greatly improve user interaction. The study confirms that well-designed, personalized ads are essential for effective digital marketing targeted at young adults with a tech interest. It also emphasizes the importance of analyzing user data and behavior patterns to make ads more effective. The conclusion is that personalized and visually appealing Instagram ads are key to attracting and engaging this audience, despite some limitations.

An educational psychological perspective on the use of filial therapy in mother-child relationships

Arnott, Amanda Margaret 11 1900 (has links)
The different reactions of parents to the discovery that their children had ADD/ADHD has an effect on the primary relationship established between mother and child. This is essential in the later involvement, experience and meaning attribution of the child with respect to all subsequent relationship formation on the child's journey towards his ultimate target, namely self-actualisation. It was felt that psychological intervention could help parents to bond, communicate with and relate to their children without experiencing negative feelings which would enhance parental acceptance. In this study, ten mothers were used to participate in an adapted group Filial Therapy programme. This unique therapy involves parents as the primary agents to resolve child-related problems and to encourage children's healthy psycho-social development. Results were positive. The mothers felt that they had formed better relationship with their children. They were empowered with knowledge and coping mechanisms, such as reflective listening, setting limits and providing choices. For the first time they were enjoying their ADD/ADHD children. / Psychology of Education / M. Ed. (Guidance and Counselling)

Germline determinants of 5-fluorouracil drug toxicity and patient survival in colorectal cancer

Rosmarin, Daniel Norris January 2013 (has links)
Despite a decade of publications investigating the effect of germline polymorphisms on both toxicity related to treatment with 5-fluorouracil-based (5-FU) chemotherapy and prognosis following diagnosis with colorectal cancer (CRC), few genetic biomarkers have been identified convincingly. For 5-FU toxicity and CRC prognosis, in four results chapters, this thesis aims to validate previously-reported genetic biomarkers, identify new markers, determine the mechanistic basis of associated polymorphisms, and expand upon methods in the field. The first three results chapters investigate genetic biomarkers for the prediction of toxicity caused by 5-FU-based treatment, particularly for the 5-FU prodrug capecitabine (Xeloda®, Roche). In the first, a systematic review and meta-analysis is performed for all variants that have been previously studied for an association with toxicity caused by any 5-FU-based drug regimen. 16 studies are analysed, including 36 previously-studied variants. Four variants show strong evidence of affecting a patient’s risk of global (any) 5-FU-related toxicity upon analysis of both the existing data and over 900 patients from the QUASAR2 trial of capecitabine +/- bevacizumab (Avastin®, Roche/Genentech): DPYD 2846, DPYD *2A, TYMS 5’VNTR and TYMS 3’UTR. Next, 1,456 polymorphisms in 25 genes involved in the activation, action or degradation of 5-FU are investigated in 1,046 patients from QUASAR2. At a Bonferroni-corrected p-value threshold of 3.43e-05, three novel associations with capecitabine-related toxicity are identified in DPYD (rs12132152, rs7548189, A551T) and the previously-identified TYMS 5’VNTR and 3’UTR toxicity polymorphisms are refined to a tagging SNP (rs2612091) downstream of TYMS and intronic to the adjacent ENOSF1, the latter of which appears to be functional. Finally, a genome-wide investigation of 4.77 million directly genotyped or imputed SNPs identifies one variant (rs2093152 on chr20) as significantly associated with capecitabine-related diarrhoea (p<5e-08), though no associations meet this threshold for global toxicity. In the study of CRC prognosis, a severe left truncation to the VICTOR trial is defined and shown to probably reduce statistical power but not bias effect estimates. Applying standard and novel genome-wide analysis approaches, a set of 43 SNPs are prioritised for future work. With over one million new CRC cases annually, this work helps define biomarkers that could become broadly applicable in the clinical setting.

Représentations sociales et opérations discursives en politique : enjeux de spectacularisation

Lalancette, Mireille 05 1900 (has links)
Cette thèse porte sur les représentations sociales. Fruit d’un bricolage conceptuel, ces représentations s’inspirent en partie des travaux de Serge Moscovici et de certains auteurs plus contemporains qui s’inscrivent dans son prolongement, dits de l’école française des représentations sociales, ainsi que d’auteurs anglo-saxons qui travaillent à partir de ce concept. Les écrits d’autres chercheurs, dont Stuart Hall, Richard Dyer et Jean-Michel Berthelot, qui adoptent dans des perspectives plus particulièrement liées aux Cultural Studies et à la sociologie ont également aidé à préciser notre façon d’envisager les représentations sociales et d’appréhender leur fonctionnement. Plus précisément, à la suite de Jodelet (1989), nous envisageons les représentations comme des « formes de connaissances socialement élaborées et partagées, ayant une visée pratique et concourant à la construction d’une réalité commune à un ensemble social » (p. 36). Ces représentations possèdent également d’autres particularités. Elles sont, d’après nous, constitutives ainsi que formées par des procédés langagiers qui rendent possibles des opérations. Ce concept nous permet d’étudier les représentations du point de vue de leur effectivité, soit de leur capacité à influencer les significations, à apporter un changement dans la manière d’interpréter une situation et, ce faisant, d’affecter les pratiques et d’induire une différence dans le monde. Ce questionnement au sujet des représentations se déploie sur un terrain qui nous semblait particulièrement riche pour en étudier le fonctionnement, soit celui de la politique qui, par ailleurs, se déroule actuellement dans un contexte de spectacularisation. Présenté comme un brouillage des genres entre divertissement et politique, ce phénomène est également lié à l’avènement de la celebrity politics, à la personnalisation et à l’évaluation, à l’importance prise par le style en politique ainsi qu’à la dramatisation, la fragmentation et la normalisation. Plus précisément, nous étudions les représentations dans un contexte de spectacularisation à partir de trois corpus documentant des événements aussi distincts que les fusions municipales en 2001, la montée en popularité de Mario Dumont et de l’ADQ en 2002 et 2003 ainsi que la série Bunker, le cirque, diffusée à la télévision de Radio-Canada à l’automne 2002. Ces corpus regroupent des textes de sources et de format variés, des textes de loi aux éditoriaux en passant par des dramatiques télévisuelles et des forums électroniques. Nous y avons effectué une analyse itérative et transversale des discours afin de mieux comprendre le fonctionnement des représentations dans un contexte de spectacularisation. Nos analyses ont démontré la variété des procédés et des opérations, telles que l’incontestabilisation, la projection, la localisation, l’amplification, la réduction et l’évaluation, qui permettent de modifier le sens et les enjeux des événements discutés. Les analyses ont également permis d’illustrer que les procédés et les opérations qu’ils rendent possibles balisent les frontières de l’objet et offrent un système classificateur. / This doctoral dissertation deals with social representations. Resulting from a conceptual bricolage, these representations are inspired, among others, by the work of Serge Moscovici and a number of more contemporary followers, also known as the French school of social representations, as well as some English authors exploring the same concept. The writings of other researchers, such as Stuart Hall, Richard Dyer and Jean-Michel Berthelot, which are rooted in a perspective related to Cultural Studies and to sociology, have also helped us define our own approach to social representations, and understand how they operate. More specifically, we consider representations, based on Jodelet (1989), as “socially constructed and shared forms of knowledge, having a practical goal and contributing to the production of a common reality for a social group” (p. 36). These representations also possess other characteristics. They are, according to us, constitutive, as well as shaped by language processes, which make possible a number of operations. This concept allows us to study representations from the perspective of their effectivity, meaning their capacity of influencing significations, of changing the way in which a situation is interpreted and, ultimately, of modifying practices and making a difference in the world. These questions with regards to representations unfold in a research field, politics in a context of spectacularization, which appeared to us especially rich for studying how they work. Presented as a confusion of genre between entertainment and politics, this phenomenon is also related to the advent of celebrity politics, to personalization and to assessment, to the growing place taken by style in politics, as well as to dramatization, fragmentation and normalization. More specifically, we have studied those representations in a context of spectacularization based on three corpuses documenting events as different from each other as city amalgamations in Quebec in 2001, the rise of Mario Dumont and the ADQ in 2002 and 2003, and the show Bunker, le cirque broadcasted on Radio-Canada television in the fall of 2002. These corpuses include texts of different formats coming from various sources, such as Acts, editorials, TV dramas and websites. We have conducted an iterative, inductive and cross-corpuses discourse analysis in order to better understand how representations work in a context of spectacularization. This analysis has demonstrated the variety of processes and operations, such as incontestabilization, projection, localization, amplification, reduction and assessment, which modify the meaning and stakes of the events selected. The analysis allowed us to illustrate that processes and operations made by representations define the limits of an object and offer a system of classification.

Processus unifié pour la personnalisation des activités pédagogiques : méta-modèle, modèles et outils / Unified process for personalization of pedagocal activities : meta-model, models and tools

Lefèvre, Marie 01 December 2009 (has links)
Cette thèse en informatique se situe dans le domaine des Environnements Informatiques pour l’Apprentissage Humain (EIAH). Dans ce cadre, nous avons abordé la question de la personnalisation de l’apprentissage. Nos travaux de recherche consistaient à identifier un processus qui permette à la fois de personnaliser des séances de travail sur papier et des séances de travail sur des logiciels pédagogiques. Nous souhaitions que ce processus permette de prendre en compte les spécificités de chaque apprenant en s’appuyant sur son profil, mais qu’il prenne également en compte les buts et les habitudes pédagogiques des enseignants. Enfin, nous souhaitions que ce processus soit implémentable dans un système externe aux logiciels à personnaliser. Notre problématique s’est donc décomposée en trois points : comment exploiter les profils d’apprenants pour prendre en compte les individualités des apprenants ? Comment adapter une activité pour prendre en compte les besoins et habitudes pédagogiques d’un enseignant ? Et enfin, comment attribuer une activité à un apprenant ? Pour répondre au premier point, nous avons proposé le modèle cPMDL. Ce complément du langage de modélisation des profils PMDL permet de contraindre les profils des apprenants afin de sélectionner ceux ayant les caractéristiques requises par les contraintes. cPMDL nous permet donc d’exploiter les informations contenues dans les profils au sein du processus de personnalisation. Pour répondre au deuxième point, nous avons proposé l’approche GEPPETO. Cette approche s’appuie sur des modèles et des processus génériques permettant d’adapter les activités en fonction des intentions pédagogiques des enseignants grâce à la définition de contraintes sur les activités. Nous avons décliné cette approche pour permettre l’adaptation des activités papier (GEPPETOP), ainsi que pour l’adaptation des activités logicielles et de la configuration des environnements qui les supportent (GEPPETOS). Pour répondre au troisième point, nous avons proposé le modèle PERSUA2 qui permet de lier les contraintes sur profils de cPMDL aux contraintes sur activités de GEPPETO. Ces liens, nommés règles d’affectation, sont ensuite hiérarchisés selon leur degré de priorité pour former une stratégie pédagogique qui sera associée { un ou plusieurs contextes d’utilisation. Nous avons mis en oeuvre ces différentes contributions théoriques dans Adapte, un module de l’environnement informatique du projet PERLEA. Le rôle de cet environnement est d’assister l’enseignant dans la gestion de profils créés par l’enseignant lui-même ou issus de logiciels pédagogiques. Adapte est l’une des exploitations possibles des profils : le module réalisé permet de fournir à chaque apprenant des activités adaptées à son profil tout en respectant les choix pédagogiques de son enseignant. Ces activités peuvent être des activités papier proposées par le système ou des activités logicielles personnalisées par Adapte, mais effectuées dans un autre EIAH. Ce module, pleinement opérationnel, a montré la faisabilité technique de nos contributions théoriques et nous a permis de conduire des mises à l'essai auprès d'enseignants / This thesis in computer science belongs to the field of Interactive Learning Environments (ILE). In this context, we have addressed the issue of personalization of learning. Our research has consisted in identifying a process allowing one to personalize both paper working sessions and working sessions on educational software. Our goal was to design a process able to take into account the specificities of each learner, based on their profiles, but also to take into account the pedagogical goals and habits of teachers. Moreover, we had to design this process such as it could be easily implemented in a software external to the system being personalized. Our problem was therefore decomposed into three points: how to use learners’ profiles to take the individuality of learners into account? How to adapt a pedagogical activity to take the teaching needs and habits of a teacher into account? And finally, how to assign an activity to a learner? To answer the first point, we have proposed the cPMDL model. This complement of the profiles modelling language PMDL allows one to constrain the learners’ profiles to select those with the characteristics required by the constraints. cPMDL allows us to exploit the information contained in the profiles during the personalization process. To answer the second point, we have proposed the GEPPETO approach. This approach relies on generic models and processes to adapt activities according to the teachers' intentions, by defining constraints on activities. We have instantiated this approach to enable on the one hand the adaptation of paper activities (GEPPETOP) and on the other hand to enable the adaptation of software activities and the adaptation of configuration of environments that support them (GEPPETOS). To address the third point, we have proposed the PERSUA2 model which links cPMDL constraints on profiles with GEPPETO constraints on activities. Next, these links, called assignment rules, are organized into a hierarchy according to their priority degree in order to form a pedagogical strategy. This pedagogical strategy is then associated with one or more contexts of use. We have implemented these different theoretical contributions in Adapte, a module of the environment associated to the PERLEA project. The role of this environment is to assist teachers in the management of profiles created by themselves or coming from pedagogical software. Adapte is one of the possible uses of profiles: the module developed provides each learner with activities suited to their profiles, while respecting the teaching choices of the teacher. These activities may be paper activities proposed by the system or software activities personalized by Adapte but made within another ILE. This module, fully operational, has demonstrated the technical feasibility of our theoretical contributions and has allowed us to conduct experiment with teachers.

Distribuição e personalização de conteúdo multimídia em ambientes educacionais ubíquos

Araújo, Rafael Dias 06 August 2013 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Ubiquitous computing is known as the third wave of computing, which aims at making computational devices become more permeated to the users lives. It has helped people to perform their daily activities in many areas of expertise, especially in the educational domain where it assists instructors and students during their academic duties, achieving knowledge anywhere and anytime, making use of unobtrusive ways of reaching the desired content. Multimedia capture and context-awareness are two relevant subjects in ubiquitous computing research. While the former results in large amounts of digital media (e.g., video, audio, slides, text comments) being automatically produced, the latter oers the proper means to integrate and access such content. By merging the two concepts, users may benet from tools that allow them to retrieve, view and interact with the captured media artifacts. Thus, this work presents a communication model based on peer-to-peer networks, used for transferring and replicating the captured content. Furthermore, a contextual access architecture is presented for personalization and recommendation of interactive multimedia content captured in an instrumented educational environment. This architecture takes into account context information, user preferences and presentation constraints in order to personalize the access experience, tailoring it to users\' needs. As a case study, the proposals were implemented in Classroom eXperience, which is a ubiquitous computing platform for multimedia capturing designed to automatically record lectures and make them available to students. / Computação ubíqua é conhecida como a terceira onda da computação, a qual visa tornar os dispositivos computacionais mais integrados à vida das pessoas. Ela tem ajudado as pessoas a realizarem suas atividades diárias em diferentes domínios, especialmente no domínio educacional, onde auxilia instrutores e alunos durante as suas atividades acadê- micas obtendo conhecimento em qualquer lugar e a qualquer momento, fazendo uso de formas não intrusivas para recuperar o conteúdo desejado. Captura e acesso multimídia e ciência de contexto são dois importantes temas em pesquisas de computação ubíqua. Enquanto o primeiro produz automaticamente um grande volume de mídias digitais (ex., vídeo, áudio, slides, comentários de texto), o segundo oferece meios adequados para integrar e acessar tal conteúdo. Ao fundir os dois conceitos, os usuários podem se beneciar de ferramentas que lhes permitam recuperar, visualizar e interagir com os artefatos de mídia capturados. Assim, este trabalho apresenta um modelo de comunicação baseado em redes peer-to-peer, utilizado para transferência e replicação do conteúdo capturado. Além disso, uma arquitetura de acesso contextual é apresentada para personalização e recomendação de conteúdo multimídia interativo capturado em ambientes educacionais instrumentados. Essa arquitetura utiliza uma abordagem que considera informações de contexto, preferências do usuário e restrições de apresentação a m de personalizar a experiência de acesso, adequando-a às necessidades dos usuários. Como estudo de caso, as propostas foram implementadas no Classroom eXperience, que é uma plataforma de computação ubíqua para captura multimídia concebida para gravar automaticamente as aulas ministradas e disponibilizá-las posteriormente aos alunos. / Mestre em Ciência da Computação

User Responsive User Experience Design: Building a Conceptual Framework / Design av användarresponsiva användarupplevelser: Ett konceptuellt ramverk

Holm, Anders, Sundberg Kullström, Christoffer January 2015 (has links)
To a large extent, business-customer interactions are acted out on digital meeting places. When the possibilities for businesses to engage in face-to-face interactions decrease, relationship building and customer service becomes more of a challenge. Digital services are easily duplicated by competitors and with standardization of interfaces and products, customers tend to switch more frequently between providers. One area where the creation and maintenance of loyal customers appears to be highly relevant is the domain of e-banking. Studies have shown that by personalizing the experience for the user, customer loyalty can be enhanced. Existing methods of interface adaptation shifts the responsibility for the resulting user experience design from the designer to either the user or the system. However, research shows that handing over responsibility for the design to the user can damage the user experience. Furthermore, we argue that as long as computers cannot translate the meaning of what a human communicates, and understand the motivation that lies behind her actions, human designers and researchers need to own the responsibility for designing user experiences. Responsive web design differ from the concept of user responsiveness in the way that it is not truly responsive to the user but to the technical device that is used. Following a design science research methodology, this paper presents the development of a conceptual framework for user responsive user experience design (URUXD) that aims to strengthen the bond between user and provider by enabling a more relevant and personalized user experience. The conceptual framework introduces a way to design user responsive information systems that could be useful in domains where the user audience is large and diverse, as in the case of e-banking. A personalized user experience is enabled by transcending the current use of personas as design tools to also involve them in categorizing real-time users through the use of personas as mapping tools. Multiple persona sets are incorporated in the framework which gives the user experience designer the possibility of designing a holistic user experience for each persona set. The framework thus enables the incorporation of multiple GUI designs in an information system that is user responsive, without the risk of violating usability principles. / Interaktionen mellan företag och kund sker nuförtiden oftast på digitala mötesplatser. När möjligheten för företag att träffa kunden öga mot öga minskar blir det en utmaning att skapa nära affärsrelationer och förmedla bra kundservice. Med konkurrenter som enkelt kopierar digitala tjänster och med en standardisering av gränssnitt och tjänster tenderar kunder att oftare byta leverantör. Inom e-banking framstår därför skapande och upprätthållande av lojala kunder som högst relevant. Genom att personifiera användarupplevelsen kan kundlojaliteten förbättras. Befintliga metoder för gränssnittsadaption lämnar över ansvaret för den resulterande designen från designern till antingen användaren eller systemet. Men, om ansvaret för designen tilldelas användaren kan resultatet bli i en skadad användarupplevelse. Så länge datorer inte kan översätta meningen bakom vad en människa kommunicerar eller skapa en förståelse för en användares bakomliggande motivation till varför hen utför handlingar, måste mänskliga designers inneha ansvaret för designen av användarupplevelsen. Vidare skiljer sig responsiv webbdesign från konceptet användarresponsivitet i meningen att responsiv webbdesign inte är direkt responsiv mot användaren utan snarare mot den tekniska apparat som används. Genom att följa en design science forskningsmetodik utvecklades ett konceptuellt ramverk för design av användarresponsiva användarupplevelser (user responsive user experience design (URUXD)). Målet var att stärka bandet mellan användare och leverantör genom att möjliggöra en mer relevant och personifierad användarupplevelse. Det konceptuella ramverket introducerar ett sätt att designa användarresponsiva informationssystem vilket kan vara användbart i domäner där användargruppen är stor och heterogen, vilket är fallet för e-banking. En personifierad användarupplevelse möjliggörs genom att utöka det befintliga användningsområdet för designverktyget personas till att även inkludera dem som mappningssverktyg för att kategorisera användare i realtid. Multipla persona sets införlivas i ramverket vilket skapar möjlighet för designern att skapa en holistisk användarupplevelse för varje enskilt persona set. Det konceptuella ramverket möjliggör därigenom för multipla gränssnittdesigns för ett informationssystem som därmed blir användarresponsivt, utan att underminera principer för användbarhet.
