Social commerce no Brasil: uma perspectiva do usuário / Social Commerce in Brazil: an user perspectiveMagalhães, Alexandre Sanches 02 September 2013 (has links)
A internet tem apresentado forte crescimento desde o final dos anos 1990. Na metade dos anos 2000, o fenômeno das mídias sociais inicia-se. No Brasil, o Orkut foi um dos desbravadores desde novo mercado, hoje dividido por empresas como Youtube, Facebook, Linkedin, Twitter e tantos outros. O internauta brasileiro adotou as mídias sociais e aparece na lista de maiores usuários desta mídias. Aconteceu isso com o Orkut, acontece isso com o Youtube, com o Facebook, com o Twitter, e o fenômeno merece ser acompanhado de perto pela academia. Pesquisando sobre o crescimento das mídias sociais, apareceu uma maneira de vender produtos, um misto de e-commerce e mídia social, chamado de social commerce. Nele, uma empresa oferece um produto para um usuário de mídia social, para que este presenteie um amigo ou conhecido nesta rede social, baseado nas declarações deste amigo ou conhecido. Seria este modelo viável no Brasil? Quais os elementos importantes para que esse tipo de comercio avance no Brasil? Este é o objeto de estudo desta tese de doutorado. / The internet hás been presenting a strong growth since the final of the 1990´s.

Internet-based electronic payment systemsKortekaas, Birgit Friederike 01 January 2002 (has links)
As today, the traditional payment systems of cash, cheques and credit cards are being
supplemented by electronic cheques, electronic credit card-based systems, and token-based
systems, online security is of utmost importance and one of the biggest criteria
used for evaluating electronic payment systems. Electronic payment systems must
guarantee the essential security requirements: confidentiality, privacy, integrity,
availability. authentication, non-repudiation as well as anonymity and trust. This paper
compares the various payment systems (both traditional and electronic) available today
mainly according to their security aspects. Secure processing can be accomplished
including access controls and detection techniques, such as, encrypted communication
channels, user and/or message authentication, symmetric and asymmetric encryption,
digital certificates and firewalls. These effective security measures, which are outlined in
detail in this paper, will protect the information and payment systems against security
risks that currently threaten the Internet / Computing / M.Sc. (Information Systems)

From traditional to IT mediated interorganizational relationships: sensemaking of the internetLambotte, François 20 December 2006 (has links)
“We provide a solution that allows saving 15 to 20 euros per invoice.It is very important in a strategy of service and cost reductions for our customers and for us.”<p><p>“For us, it is very important as we generally reduce our inventories by 30%, thus we recover cash flow. It is not negligible.”<p><p>These quotes out of my case studies show that the primary goal of the implementation of Web-based applications is the achievement of transaction cost efficiencies: cost cutting, time saving, and information integration. But do they achieve such results? Sometimes they do sometime they don’t. In order to understand why, I consider it is necessary to take a different perspective from the one taken until now. <p><p>Indeed, existing studies on interorganizational information systems focus on economical and strategic issues and consider organizations as opaque entities. First, issues at hand may not be economic or strategic but social or legal. Next, they neglect that inter-organizational relationships imply a number of long-standing social interactions between individuals of each organization. Moreover, these individuals interpret the mediation project and act taking decision, implementing, or using the mediating technology – that these individuals make sense of the IT mediation project. In the present research, I propose to open the black box of organizations and explore how people sensemaking conditions the achievement of transaction cost benefits and is conditioned by the interorganizational context. My overarching research question is: How do people make sense of the Internet mediation of long-standing interorganizational relationships?<p> / Doctorat en sciences de gestion / info:eu-repo/semantics/nonPublished
