The remote control ofmobile robot on theInternet

During last decades, the Internet teleobotics has been growing at an enormous ratedue to the rapid improvement of Internet technology. This paper presents theinternet-based remote control of mobile robot. To face unpredictable Internet delaysand possible connection rupture, a direct continuous control based teleoperationarchitecture with “Speed Limit Module” (SLM) and “Delay Approximator” (DA) isproposed. This direct continuous control architecture guarantees the path error of therobot motion is restricted within the path error tolerance of the application.Experiment results show the feasibility and effectiveness of this direct Internet controlarchitecture in the real Internet environment.

The Requirements of Using Provenance in e-Science Experiments

In e-Science experiments, it is vital to record the experimental process for later use such as in interpreting results, verifying that the correct process took place or tracing where data came from. The process that led to some data is called the provenance of that data, and a provenance architecture is the software architecture for a system that will provide the necessary functionality to record, store and use process documentation. However, there has been little principled analysis of what is actually required of a provenance architecture, so it is impossible to determine the functionality they would ideally support. In this paper, we present use cases for a provenance architecture from current experiments in biology, chemistry, physics and computer science, and analyse the use cases to determine the technical requirements of a generic, technology and application-independent architecture. We propose an architecture that meets these requirements and evaluate a preliminary implementation by attempting to realise two of the use cases.

The Purely Reflected Self

Belief in the concept of the self causes suffering. Unfortunately, although conceptual constructions like this may help to define our goal—the casting off of the belief in the self—this is a much more difficult thing to actualize and attain in daily practice. Our building blocks can form a neat tower, and we can climb to the top and gaze at the horizon, but they will topple, leaving us once again over our heads in the hedgerow. Buddha describes his teachings as a raft to ford the river of suffering in order to reach the far off bank of enlightenment: as one does not take the raft after crossing the river, so we must not lean on his teachings to make our way through life. So I intend here to abandon the raft for other accounts of existence written by other thinkers, and in this my purpose is twofold: First, in reading other interpretations we can gain new tools with which to study the architecture of the concept of the self, and second, in studying the history of the concept of self as it progresses through history we can better understand the non-inherentness of this problematic construct. I intend to examine the philosophies of self in the Chinese and European traditions, and their subsequent deconstructive traditions in order to achieve this goal.

The Nine Circles of Surveillance Hell: An Institutional View of Information Flows and Information Threats in Libraries

In the past few years, libraries have started to design public programs that educate patrons about different tools and techniques to protect personal privacy. But do end user solutions provide adequate safeguards against surveillance by corporate and government actors? What does a comprehensive plan for privacy entail in order that libraries live up to their privacy values? In this paper, the authors discuss the complexity of surveillance architecture that the library institution might confront when seeking to defend the privacy rights of patrons. This architecture consists of three main parts: physical or material aspects, logical characteristics, and social factors of information and communication flows in the library setting. For each category, the authors will present short case studies that are culled from practitioner experience, research, and public discourse. The case studies probe the challenges faced by the library—not only when making hardware and software choices, but also choices related to staffing and program design. The paper shows that privacy choices intersect not only with free speech and chilling effects, but also with questions that concern intellectual property, organizational development, civic engagement, technological innovation, public infrastructure, and more. The paper ends with discussion of what libraries will require in order to sustain and improve efforts to serve as stewards of privacy in the 21st century.

Atribuição de causalidade em presos, amputados e cegos: aceitação e luta contra o infortúnio

Os objetivos deste trabalho compreendem a determinação: (a) dos processos de atribuição de causalidade e responsabilidade empregados, por sujeitos presos, cegos e amputados, na explicação dos eventos que os vitimaram; (b) da relação entre os processos de atribuição de causalidade e as respostas de combate a situação; (c) da eficácia das teorias de busca de controle, mundo justo e atribuição defensiva na explicação dos eventos por parte dos sujeitos: (d) da influência do sentimento de auto-estima, crença no mundo justo, “locus" de controle e sentimento de religiosidade, na atribuição de causalidade; (e) de como os observadores emparelhados aos atores atribuição da causalidade e responsabilidade aos eventos vitimadores. A parte inicial consiste em uma revisão das principais contribuições teóricas ao fenômenos da atribuição de causalidade em psicologia social e das pesquisas a ele relacionadas; sua extensão se justifica pela inexistência de textos desta natureza em nossa língua. A segunda parte compreende a análise das respostas a conjunto de questionários e escalas fornecidas por 43 sujeitos presos por homicídio ou assalto, 40 amputados de membro superior ou inferior, 35 cegos congênitos ou adquiridos, e de 138 sujeitos observadores a eles emparelhados em idade, nível sócio-econômico e escolaridade. Os resultados indicam diferenças no processo de atribuição de causalidade empregado pelos sujeitos com perdas diversas e na utilização de princípios das três teorias consideradas. O mesmo se verifica quando se comparam sujeitos atores e observadores. Os dados mostram ainda relações entre as variáveis psicológicas e o processo de atribuição de causalidade, bem como a influência destas variáveis no processo de luta contra a perda sofrida.

BlueFriends: measuring, analyzing and preventing social exclusion between elementary school students

Social exclusion is a relatively recent term, whose creation is attributed to René Lenoir(Lenoir, 1974). Its concept covers a remarkably wide range of social and economic problems, and can be triggered for various reasons: mentally and physically handicapped, abused children, delinquents, multi-problem households, asocial people, and other social “misfits” (Silver, 1995, pp. 63; Foucault, 1992). With an increasingly multi-cultural population, cultural and social inequalities rapidly ascend, bringing with them the need for educational restructuring. We are living in an evermore diverse world, and children need to be educated to be receptive to the different types of people around them, especially considering social and cultural aspects. It is with these goals that inclusive education has seen an increased trend in today’s academic environment, reminding us that even though children may be taught under the same roof, discriminatory practices might still happen. There are, however, a number of developed tools to assess the various dimensions of social networks. These are mostly based on questionnaires and interviews, which tend to be fastidious and don’t allow for longitudinal, large scale measurement. This thesis introduces BlueFriends, a Bluetooth-based measurement tool for social inclusion/exclusion on elementary school classes. The main goals behind the development of this tool were a) understanding how exclusion manifests in students’ behaviors, and b) motivating pro-social behaviors on children through the use of a persuasive technology. BlueFriends is a distributed application, comprised by an application running on several smartphones, a web-hosted database and a computer providing a visual representation of the data collected on a TV screen, attempting to influence children behaviors. The application makes use of the Bluetooth device present on each phone to continuously sample the RSSI (Received Signal Strength Indication) from other phones, storing the data locally on each phone. All of the stored data is collected, processed and then inserted into the database at the end of each day. At the beginning of each recess, children are reminded of how their behaviors affect others with the help of a visual display, which consists of interactions between dogs. This display illustrates every child’s best friends, as well as which colleagues they don’t interact with as much. Several tips encouraging social interaction and inclusiveness are displayed, inspiring children to change their behaviors towards the colleagues they spend less time with. This thesis documents the process of designing, deploying and analyzing the results of two field studies. On the first study, we assess how the current developed tools are inferior to our measuring tool by deploying a measurement only study, aimed at perceiving how much information can be obtained by the BlueFriends application and attempting to understand how exclusion manifests itself in the school environment. On the second study, we pile on the previous to try and motivate pro-social behaviors on students, with the use of visual cues and recommendations. Ultimately, we confirm that our measurement tool’s results were satisfying towards measuring and changing children’s behaviors, and conclude with our thoughts on possible future work, suggesting a number of possible extensions and improvements.
