Previous issue date: 2011 / Nenhuma / Atualmente, a atribuição de novas tecnologias aliadas à computação distribuída tem crescido exponencialmente devido a necessidade cada vez mais imposta de otimização dos recursos computacionais. As redes P2P (Peer-to-Peer) são um exemplo de arquitetura de sistemas distribuídos onde os nós atuam tanto na função de clientes como na de servidores. A relação desses nós participantes apresenta questões relacionadas à confiança devido as comunicações que esses realizam, e uma vez que o comportamento dos nós é dinâmico, indicam-se problemas voltados a segurança. Dessa forma, um sistema de reputação e confiança é um meio de se controlar o funcionamento da rede e demais problemas através de métodos de recompensa e penalização. Analisando o contexto de aplicação, nota-se que utilizar um mecanismo de penalização para limitar largura de banda, como acontece tradicionalmente em sistemas P2P, não é uma alternativa viável para ambientes LAN, devido justamente aos recursos que esse tipo de rede detém como característica própria. Dentre diversas outras possibilidades, a limitação de acesso às informações sobre os arquivos compartilhados evidencia adequadamente uma maneira concisa e aplicável para tratar a penalização em redes locais. Este trabalho tem como objetivo então o desenvolvimento de um sistema de reputação para redes locais, denominado TrustLP2P. O TrustLP2P propõe um modelo que visa adequar os aspectos do ambiente de rede local ao mesmo tempo em que atribui conceitos baseados em outros sistemas de reputação existentes, fazendo uso de valores de reputação e confiança para que os nós possam classificar uns aos outros. Aliado a isso, mensurando através dos valores de reputação os participantes, o sistema também tem por finalidade recompensar ou penalizar os nós de acordo com seu comportamento. Um exemplo de aplicação para o TrustLP2P é o LP2P (Local Peer-to-Peer ), uma plataforma de comunicação para ambientes distribuídos voltada para o compartilhamento de arquivos, desenvolvida pelo projeto da linha de pesquisa de Redes de Computadores e Sistemas Distribuídos do PIPCA, Unisinos. Assim, o sistema proposto proporciona ao LP2P um controle adequado sobre as ações dos nós, através de aspectos consistentes que são descritos no seu modelo. / Currently, assign new technologies designed to distributed computing has grown exponentially due to the need for optimization of computing resources. The P2P (Peer-to-Peer) is an example of architecture of distributed systems where the nodes work both in the role of client as the server. The relationship of these nodes presents issues relating to the trust due the communications between them, and since the behavior of nodes is dynamic, security problems are indicated. Thus, a reputation and trust system is one way to control the operation of the network and other problems through methods of reward and punishment. Analyzing the application context, it is notable that use a penalty mechanism to limit bandwidth, as traditionally happens in P2P systems, it is not a viable alternative for LAN environments, due to the resources that this type of network has its own characteristic. Among several other possibilities, limiting access to information about the shared _les shows a concise and applicable manner to establish the penalty in local networks. This study aims to develop a reputation system for local networks, called TrustLP2P. The TrustLP2P proposes a model that adapts aspects of the local network environment at the sime time that related concepts based on other existing reputation systems, making use of reputation and trust values so that the nodes can classify each other. Allied to this, measuring the values of reputation through the participants, the system also aims to reward or penalize the nodes according to their behavior. An application for TrustLP2P is LP2P (Local Peer-to-Peer), a communication platform for distributed environments focused on the sharing of _les, developed by the research project of Computer Networks and Distributed Systems of PIPCA, Unisinos. Thus, the proposed system provides for LP2P an adequate control over the actions of the nodes, through consistent aspects that are described in their model.

Förderung der Anerkennung in agilen SoftwareentwicklungsprozessenSchwarzer, Jan, Barnkow, Lorenz, Luck, Kai von 25 October 2013 (has links) (PDF)
Der Beruf als wesentliche Institution der Anerkennung in der modernen Gesellschaft steht im Wandel und dadurch die Anerkennungschancen und -formen der Arbeit. Fokussiert wird zunehmend Arbeit, die sich an ihrem Erfolg misst und weniger Arbeit, bei welcher die Leistung an sich im Vordergrund steht. Dadurch wird die Wertlosigkeit bestimmter Beschäftigungsgruppen gefördert sowie die De-Institutionalisierung der Anerkennung im Beruf gestärkt. Zudem entfallen durch immer flacher werdende Unternehmens-Hierarchien auch Möglichkeiten Anerkennung durch Positionssymbole auszurücken. Dies bedeutet, dass die Sichtbarmachung von Leistung und des Sich-Sichtbarmachens an Wichtigkeit gewinnt. (...)

Trustworthiness of voice-based assistants: Integrating interlocutor and intermediary predictorsWeidmüller, Lisa, Etzrodt, Katrin, Engesser, Sven 01 March 2024 (has links)
When intelligent voice-based assistants (VBAs) present news, they simultaneously act as interlocutors and intermediaries, enabling direct and mediated communication. Hence, this study discusses and investigates empirically how interlocutor and intermediary predictors affect an assessment that is relevant for both: trustworthiness. We conducted a secondary analysis using data from two online surveys in which participants (N = 1288) had seven quasi-interactions with either Alexa or Google Assistant and calculated hierarchical regression analyses. Results show that (1) interlocutor and intermediary predictors influence people’s trustworthiness assessments when VBAs act as news presenters, and (2) that different trustworthiness dimensions are affected differently: The intermediary predictors (information credibility; company reputation) were more important for the cognition-based trustworthiness dimensions integrity and competence. In contrast, intermediary and interlocutor predictors (ontological classification; source attribution) were almost equally important for the affect-based trustworthiness dimension benevolence.

The legal implications of defamatory statements on social media platforms in South Africa / Leonhard Hugo HomannHomann, Leonhard Hugo January 2015 (has links)
With the fast pace that technology is currently developing, technology forms a bigger
part of our day to day lives. Technological advancement has an impact on all aspects of
life, including how we communicate with one another. This has caused an increase in
social media usage. South Africa is in no way an exception to this growing trend. The
escalation of the use of social media platforms has brought with it the rise in the
wrongful use of social media. The growth in wrongful use would lead to the proliferation
of legal consequences for defamatory statements with regard to social media situations.
The question arises if South Africa‘s current legislation is able to regulate the new
phenomena of defamatory statements on social media platforms. The conclusion was
reached that South Africa‘s current legislation is more than adequate to regulate this
new form of defamation. With the qualification that that judges apply the current legal
principles of the law of delict to this new form of defamation correctly. Educating and
informing judges, as well as the public is vital in preventing this new form of defamation
to become problematic. / LLM, North-West University, Potchefstroom Campus, 2015

Consumer preferences for emerging trends in organics: product origin and scale of supply chain operationsPozo, Veronica F. January 1900 (has links)
Master of Science / Department of Agricultural Economics / Hikaru H. Peterson / Alexander E. Saak / Notable changes are occurring in the U.S. organic food sector. First, the U.S. organic food system is increasingly relying on imports, because the expansion in the organic production has failed to satisfactorily meet the rapidly growing demand for organic foods. Second, the “locally grown” concept has become appealing to consumers, with some evidence of consumers switching from certified organic foods to local, conventional foods. Third, organic food has penetrated the mass-market channel, and organic foods are no longer being sold exclusively in natural product stores. And fourth, the social and environmental awareness among consumers is increasing. Thus, consumers are also willing to pay a price premium to support small farmers. To understand how these changes are affecting the demand for organic foods, this study used survey data to assess U.S. consumers‟ preferences for fresh organic apples that are sourced from various places and from supply chain operations that vary in scale. The survey was administered via the Internet to a random sample of 285 households across the U.S through a research company. Choice experiment was selected as the valuation method.
Results indicate that among the levels of the location attributes, the “locally grown” label was associated with the highest average WTP. The “regionally grown” was the second most preferred, “U.S. grown” the third, and “imported” the least. The “locally grown” label was valued higher than the “certified organic label”. Also, consumers were willing to pay a higher value for apples produced on a small farm compared to those from a large farm. However, they did not distinguish the type of retail outlets where apples were offered. The analysis incorporating the effects of consumer characteristics suggest that the perceived importance of public benefits impacted the values of origin attributes more than the private ones; the type of retail outlet attributes became significant among certain gender and age segments; and the value of small farm attribute increased with consumers‟ income. Finally, results from a theoretical model suggest that the variability in the WTP obtained among the origin attributes could be explained by the reputation of product quality depending on their origin.
