Collaborative Learning Using Collaboration Technology: Report from the Field
No full textWe propose that emerging collaboration, or groupware, technology that supports synchronous interaction among students and faculty can add new aspects to the traditional distance learning and university course models. To explore this assumption we taught a masters' level university course using collaboration technology. In our approach, collaboration technology (integrated synchronous audio- and video-conferencing, electronic whiteboard and shared application tools) was used to provide students at universities in different countries opportunities to participate in interactive class exercises and discussions, and to do class assignments together. Students also participated in traditional, face-to-face class seminars, discussions and exercises at their local university. Thus students learned using collaboration technology and traditional methods. In this paper we describe the course and discuss students' evaluations of the course, their collaboration with each other, and collaboration technology used during the course. Students evaluated the course and their collaborative experiences very highly but reported unique challenges and had mixed impressions with respect to the technology. Challenges included establishing interpersonal communication and meeting commitments. In general, students judged collaboration technology lower than e-mail and telephony in characteristics such as social presence, participation and ease of use. However, there were differences in evaluations among students in Chapel Hill and Oulu implying cultural preferences. In addition, students reported varying degrees of productivity and variety of tasks afforded the technology. These differences were similar for students in Chapel Hill and Oulu, implying individual preferences influenced evaluation of the technology. These results appear to imply that students need to learn principles of collaboration in addition to the technology for collaborative learning across distances to occur, and that a variety of technologies are needed to accommodate cultural and individual differences among students
Assessment of the statistical relevance of TR-PIV datasets
No full textThe increasing interest for high repetition rate global optical measurement techniques such as Time-Resolved Particle Image Velocimetry (TR-PIV) raises a number of questions concerning their ability to provide relevant statistical and spectral quantities. In an effort to address this issue, complementary TR-PIV and Laser Doppler Velocimetry (LDV) measurements have been carried out. An application to the analysis of the detached flow over a NACA 0015 airfoil at a Reynolds number Re=105 in a water tunnel is proposed
Building a culture of research: Using undergraduate research to advance the TR profession, build research capacity, and foster collaborative relationships
No full textThe purpose of this paper is to provide a rationale for rethinking the role of undergraduate research and to describe Douglas College's innovative approach to developing a research culture through fostering undergraduate therapeutic recreation (TR) students' research skills. In the literature review we. build the case for an undergraduate research-based curriculum as an essential step in building a research culture. A research skills development framework (Willison & O'Regan, 2007) is presented as a way to view research skills and to understand how a student might progress and develop research competence. The role of collaboration is examined as an intimate and essential aspect of building a research culture. We present the initiatives and ideas that Douglas College has used in its quest to create a research ethos that embraces not only the TR Department but also the TR community, and conclude by outlining future steps to continue the work at Douglas, including reaching out to other educational institutions to collaborate on research projects.

Interface Currents : evaluating a fluid interface for tabletop collaboration
No full textMasters ThesisLarge screen vertical and horizontal displays provide new opportunities to support individual and collaborative activities especially in terms of creativity and design tasks. The size of these displays introduces several unique opportunities such as co-located collaboration but at the same time issues for interface designers such as: potential difficulties of reaching workspace items far away from one’s current position at the display, and the tendency of people to walk around when using a wall display or sit in various positions around a tabletop display. Thus, in contrast to traditional interfaces, large display interfaces need to support access to workspace items from a variety of positions at the display. In order to improve access to workspace items, providing better support for obtaining and sharing items and for mobility at the display which can be very important to improve creative processes, we propose a novel interaction metaphor, the so-called Interface Current, that allows interface components to play a more active role in the workspace activity
Does Partnering Pay Off? - Stock Market Reactions to Inter-Firm Collaboration Announcements in Germany
No full textThe dramatic increase in interorganizational partnering in the last two decades raises questions for scholars and managers regarding the value impact of inter-firm collaborations. Using event study methodology, this paper tests whether stock market reactions differ when a collaboration formation or termination is announced. In addition, the study provides an in-depth analysis of potential determinants of stock market reactions to collaboration formation announcements. The sample consists of 1037 announcements in German stock markets from 1997 to 2002. The results show that an unexpected termination announcement decreases firm valuation, and a formation announcement increases firm valuation. Further, certain collaborations are more favorable than others, depending on firm industry, age, size, collaboration constellations, and equity versus non-equity investment in partner firm. The results open avenues for further research on partnering strategies
Single Display Groupware: A Model for Co-present Collaboration
No full textWe introduce a model for supporting collaborative work between people that are
physically close to each other. We call this model Single Display Groupware
(SDG). In this paper, we describe this model, comparing it to more traditional
remote collaboration. We describe the requirements that SDG places on
computer technology, and our understanding of the benefits and costs of SDG
systems. Finally, we describe a prototype SDG system that we built and the
results of a usability test we ran with 60 elementary school children.

Kustverdediging na 1990 (Kustnota 1990): Technisch rapport 11: Strand en duinsuppleties
No full textIn Technisch Rapport 11 (TR 11) wordt een overzicht gegeven van de strand- en duinsuppleties, welke ter compensatie van kusterosie zijn uitgevoerd. In 1988 is het "Handboek zandsuppleties" uitgegeven. Hierin is een schat van gegevens verzameld over het desbetreffende onderwerp. Dit rapport voorziet in een aanvulling op het handboek, met meer recente gegevens. Overlapping van dit rapport met het handboek is zoveel mogelijk vermeden. Naast de aanvulling wordt ingegaan op de levensduur van suppleties en wordt een eerste aanzet gegeven om een puur economische afweging te maken tussen zandsuppleties, die nu een belangrijke maatregel bij kustverdediging zijn, en de bouw van strandhoofden, wat in het verleden een belangrijke maatregel geweest is. Zand wordt met grote drijvende werktuigen relatief goedkoop, als zandwatermengsel, verplaatst. Een netto-verplaatsing van 200.000 tot 500.000 kubieke meter zand per werktuig, per werkweek is haalbaar. Naarmate het zand hoger en verder op de oever gebracht wordt nemen de kosten toe.Kustnot
A Web-Service Based Approach for Software Sharing
No full textA Web-service based approach is presented which enables geographically dispersed users to share software resources over the Internet. A service-oriented software sharing system has been developed, which consists of shared applications, client applications and three types of services: application proxy service, proxy implementation service and application manager service. With the aids of the services, the client applications interact with the shared applications to implement a software sharing task. The approach satisfies the requirements of copyright protection and reuse of legacy codes. In this paper, the role of Web-services and the architecture of the system are presented first, followed by a case study to illustrate the approach developed
A Preliminary Statistical Investigation into the impact of an N-Gram Analysis Approach based on Word Syntactic Categories toward Text Author Classification
No full textQuantitative analysis of literary style has heretofore utilized semantic elements-word counts. This research attempts to identify quantifiable syntactic elements of style that can be used for author identification. The measurement of syntactic elements utilizes a dictionary with one part of speech per word and looks at phrases delimited by punctuation marks. Different size permutations of words - referred to as grams - are counted within each text. Correlations are measured amongst the gram frequencies of eight texts pertaining to four authors, both contemporary and non-contemporary. The correlations are performed across different gram sizes of words. The same treatment is applied to a target text, the Funeral Elegy text. The approach holds for classifying texts temporally consistently across the various gram sizes. Yet a finer grained investigation is required to certify the authorship of the Funeral Elegy text.
