PERCEPOLIS: Pervasive Cyberinfrastructure for Personalized Learning and Instructional Support  [PDF]
Ali R. Hurson, Sahra Sedigh
Intelligent Information Management (IIM) , 2010, DOI: 10.4236/iim.2010.210067
Abstract: This paper describes PERCEPOLIS, an educational platform that leverages technological advances, in particular in pervasive computing, to facilitate personalized learning in higher education, while supporting a networked curricular model. Fundamental to PERCEPOLIS is the modular approach to course development. Blended instruction, where students are responsible for perusing certain learning objects outside of class, used in conjunction with the cyberinfrastructure will allow the focus of face-to-face meetings to shift from lecture to active learning, interactive problem-solving, and reflective instructional tasks. The novelty of PERCEPOLIS lies in its ability to leverage pervasive and ubiquitous computing and communication through the use of intelligent software agents that use a student’s academic profile and interests, as well as supplemental information such as his or her learning style, to customize course content. Assessments that gauge the student’s mastery of concepts are used to allow self-paced progression through the course. Furthermore, the cyberinfrastructure facilitates the collection of data on student performance and learning at a resolution that far exceeds what is currently available. We believe that such an infrastructure will accelerate the acquisition of knowledge and skills critical to professional engineering practice, while facilitating the study of how this acquisition comes about, yielding insights that may lead to significant changes in pedagogy.

Abstract: Once deployed, sensor networks are capable of providing a comprehensive view of their environment. However, since the current sensor network paradigm promotes isolated networks that are statically tasked, the full power of the harnessed data has yet to be exploited. In recent years, users have become mobile enti-ties that require constant access to data for efficient and autonomous processing. Under the current limita-tions of sensor networks, users would be restricted using only a subset of the vast amount of data being col-lected; depending on the networks they are able to access. Through reliance on isolated networks, prolifera-tion of sensor nodes can easily occur in any area that has high appeals to users. Furthermore, support for dy-namic tasking of nodes and efficient processing of data is contrary to the general view of sensor networks as subject to severe resource constraints. Addressing the aforementioned challenges requires the deployment of a system that allows users to take full advantage of data collected in the area of interest to their tasks. Such a system must enable interoperability of surrounding networks, support dynamic tasking, and swiftly react to stimuli. In light of these observations, we introduce a hardware-overlay system designed to allow users to efficiently collect and utilize data from various heterogeneous sensor networks. The hardware-overlay takes advantage of FPGA devices and the mobile agent paradigm in order to efficiently collect and process data from cooperating networks. The computational and power efficiency of the prototyped system are herein demonstrated. Furthermore, as a proof-of-concept, we present the implementation of a distributed and autonomous visual object tracker implemented atop the Reconfigurable and Interoperable Sensor Network (RISN) showcasing the network’s ability to support ad-hoc agent networks dedicated to user’s tasks.

Abstract: Gibt es einen Anspruch des Menschen auf physische und psychische Integrit t? Wie hat sich ein solcher Anspruch entwickelt und auf welchen Grunds tzen kann er beruhen? Das Menschenrecht auf die Unversehrtheit des K rpers wird im vorliegenden Sammelband sowohl aus geschichtlicher, literaturtheoretischer, politischer als auch aus islamwissenschaftlicher, soziologischer und juristischer Perspektive beleuchtet. Dabei setzen sich die Autoren und Autorinnen mit den derzeit vorliegenden Argumentationsfiguren zur Begründung der Menschenrechte als elementarem Recht auseinander und leisten mit ihren Analysen, Kritiken und Konfrontationen einen innovativen Beitrag zu den aktuellen Debatten um Folter, k rperlicher Unversehrtheit und Verantwortung. Do humans have an entitlement to physical and psychic integrity? How did such entitlement develop and on what basic tenants does it rest? The collected volume at hand illuminates the human right to physical integrity from the perspective of history, literary theory, politics as well as Islamic studies, sociology, and law. The authors approach current arguments justifying human rights as a fundamental right. Their analyses, critiques, and confrontations provide an innovative contribution to the current debates on torture, physical integrity, and accountability.

querelles-net , 2008,
Abstract: Lutz Hieber und Paula-Irene Villa setzen sich sowohl aus soziologischer als auch aus kulturwissenschaftlicher und politischer Perspektive mit der Historie und Aktualit t von Queer Theory auseinander. Grundlegende theoretische Debatten und Denkfiguren wie Postmodernismus, Feminismus in der Postmoderne oder auch Kritik von Identit t und Normalisierung werden anschaulich dargestellt. Gleichzeitig werden gewinnbringende Akzente in Form von Analysen verschiedener Praxen von Politik, wie etwa der Politisierung von Kunst, gesetzt. Insgesamt werden auf gelungene Weise erstens spezifische Begriffe der Queer Theory in ihre jeweiligen Kontexte eingeordnet und erl utert und zweitens spezifische Formen und M glichkeiten politischer Praxis dargelegt. Lutz Hieber and Paula-Irene Villa examine the history and topicality of Queer Theory from the perspective of sociology, cultural studies, and politics. They depict essential theoretical debates and thinkers such as postmodernism, feminism in postmodernism, or the critique of identity and normalization. At the same time they place lucrative accents in the form of analyses of differing political practices, such as of the politicization of art. Overall the study successfully presents firstly, the terminology of Queer Theory ordered into their respective contexts and explained and secondly, specific forms and possibilities of political practice.

querelles-net , 2009,
Abstract: Das vorliegende Buch erm glicht einen, wenn auch streckenweise langwierigen, so doch umfangreichen Zugang zu postmodernen und feministischen Texten, die sich mit dem Signifikant Subjekt‘ auseinandersetzen. Zentrale theoretische Texte franz sischer Poststrukturalisten (Lacan, Derrida, Foucault) über Vertreterinnen des french feminism“ (Cixous, Irigaray, Kristeva) und deutscher Kulturwissenschaftlerinnen (Weigel Gro ma , Schmerl) sowie postfeministischer und postkolonialistischer Autorinnen (Butler, Haraway, Minh-ha) werden vorgestellt und in ihre theoretischen Kontexte eingeordnet. The book at hand offers a comprehensive, if sometimes long-winded, approach to postmodern and feminist texts that deal with the signifier “subject.” It introduces central theoretical texts and places them in theoretical context, including texts by French poststructuralists (Lacan, Derrida, Foucault), by representatives of “French feminism” (Cixous, Irigaray, Kristeva), and by German scholars of cultural studies (Weigel, Gro ma , Schmerl), as well as texts by postfeminist and postcolonial authors (Butler, Haraway, Minh-ha).
Gaja von Sychowski: Geschlecht und Bildung. Beitr ge der Gender-Theorie zur Grundlegung einer Allgemeinen P dagogik im Anschluss an Judith Butler und Richard H nigswald. Würzburg: Verlag K nigshausen & Neumann 2011.

Abstract: In der Ver ffentlichung ihrer Habilitationsschrift geht Gaja von Sychowski das Vorhaben an, eine Allgemeine P dagogik im Kontext poststrukturalistischen Denkens zu entwerfen. Damit greift sie nicht nur ein l ngst überf lliges Thema auf, es gelingt ihr zudem, dieses auf h chstem theoretischem Niveau zu bearbeiten. Die formalistische Konsequenz, mit der die Autorin ihre Forschung vorantreibt, ist dabei jedoch zwiesp ltig: Zwar schl gt sie durch die Reduzierung von Komplexit t Brücken zwischen verschiedenen Disziplinen, andererseits verliert Geschlecht, wenn es schlie lich unter Performanz subsumiert wird, an Bedeutung, und es entsteht so der Grundriss einer Allgemeinen P dagogik, in welcher die subjektkonstituierende Macht von Geschlecht unterschlagen wird. In the publication of her professorial dissertation, Gaja von Sychowski intends to design a general pedagogy within the context of poststructuralist thinking. In doing so, she not only addresses a long overdue topic, but she also succeeds in elaborating it on a most abstract level. However, the formalistic consistency that the author uses to advance her research is ambivalent: on the one hand, the reduction of complexity bridges gaps between different disciplines, on the other hand, gender loses meaning if it is eventually subsumed under performance. Consequently, an outline of a general pedagogy, which omits the subject-constituting power of gender, emerges.
