Wiki a la carte: Understanding participation behaviors
Authors: Shachaf Pnina , Hara Noriko , Bonk Curt , Mackey Thomas P. , Hemminger Bradley , Stvilia Besiki , Rosenbaum Howard 
Published: February 2009

AbstractThis panel focuses on trends in research on Wikis. Wikis have become prevalent in our society and are used for multiple purposes, such as education, knowledge sharing, collaboration, and coordination. Similar to other popular social computing tools, they raise new research questions and have attracted the attention of researchers in information science. While some focus on the semantic web, the automatic processing of data accumulated by users, and tool improvements, others discuss social implications of Wikis. This panel presents five studies that address the social uses of Wikis that support information sharing. In their studies, the panelists use a variety of novel applications of research methods, such as action research, and online ethnography, site observation, survey, and interviews. The panelists will present their findings: Shachaf and Hara will discuss Wikipedians' norms and behaviors; Bonk will present collaborative writing on Wikibook; Mackey will discuss authorship and collaboration in PBwiki.com; Hemminger will share results from the early use of wikis for conference communications; and Stvilia will outline the community mechanism of information quality assurance in Wikipedia.

Published: February 2009

Abstract“Every university in the world can and should have its own open‐access, OAI‐compliant repository…” Suber 2006Panel goals: Panel members, each of whom brings different expert knowledge about institutional repositories (IR), will take turns answering a set of provocative questions about the future of IR and challenges inherent in ongoing management of IR. Panelists will also be given an opportunity to respond to each others' comments and audience members will also contribute questions to the discussion. The debate style format will give audience members a rich understanding of the challenges related to IRThe IR experts on this panel will debate the future of IR in academic institutions globally. Specific questions the moderator will pose to the panelists may include the following:

How will IRs come to vary across in 10 years in terms of presence or absence, but also in terms of the types of materials collected? (e.g., preprints versus local digital collections)?
What will the relationship between university libraries and disciplinary IRs be in 10 years? What will be the relationship between IR and scholarly societies, especially those which publish journals?
Under what circumstances will consortial or outsourced efforts become popular?
Under what circumstances should we expect increases in deposit activity among researchers and faculty?
Under what circumstances will IRs change the status of developing nation scholars and the typical flows of scholarly communications?
How would our investments in IR be assessed? From an economic/financial perspective? From a status perspective? From the promotion and tenure perspective? From an open access perspective?
How will IR be funded in the long term?
Questions from the audience will be welcomed.
The complexity and value of managing in the digital environment
Authors: Detlor Brian , Turnbull Don , Mackenzie Maureen , Smith James P. 
Published: February 2009

AbstractThis session combines individual presentations with a group discussion. The focus of this session and the expertise of this panel bring together ways of coordinating, evangelizing and adapting in organizations that are more connected digitally than physically. The digital environment is both a management blessing and a burden. The panelists offer varying viewpoints and perspectives into our expanding digital world.The panel session will begin with a brief description of the panel's overall theme and its relevance and importance to the broader ASIST community. This will set the stage and provide context to the three individual panelist presentations. Each panelist will situate his or her talk in context to the overall theme and will elicit key insights and recommendations pertaining to this theme. This should provide a powerful mechanism to engage conversation and the sharing of ideas between panel members and audience participants.This session reflects the interests of SIG‐MGT membership and aligns with the ASIST 2007 theme of “Joining Research and Practice: Social Computing and Information Science”
Seeking knowledge in a social world: Epistemological pathways
Authors: Meyers Eric M. , Dirndorfer Anderson Theresa , Sundin Olof , Unsworth Kris 
Published: February 2009

AbstractEpistemology – the study of knowledge and knowing – is of central concern to information science (Budd, 2001; Dick, 2002; Hjørland, 2002). Jesse Shera, who coined the term social epistemology with Margaret Egan, suggested that information science is intimately connected to the “production, flow, integration and consumption of all forms of communicated thought throughout the entire social fabric” (1970: 86). Aiding people in the acquisition of knowledge thus becomes the sine qua non of information services and technologies (Fallis, 2006). As social computing and advances in information and communications technologies (ICTs) change the way we seek and use information personally and professionally, it becomes critical that information scientists understand how social processes influence knowledge acquisition. This panel explores empirically and theoretically how people seek and construct knowledge in a social world.
No title

AbstractIntroductionWe are moving rapidly into a new phase of the digital environment colloquially labelled Web 2.0. Characterized by the emergence of powerful applications that allow and encourage the formation of different types of social networks, Web 2.0 is changing the nature of online communities. The rich applications that form the infrastructure that supports these communities include blogs, wikis, RSS, social tagging, folksonomies and others. These 2.0 technologies also enable an architecture of participation, an outcome of which are vast and growing troves of data and information. These digital artefacts are the raw materials of memory; the infrastructures of these online communities shape and guide the emergence of memory – what is remembered and what is forgotten.How can this phenomenon be studied? If it can be studied, what are some useful theoretical and methodological strategies that can be brought to bear? In the panel, we propose to explore the issues involved in the study of “memory practices, ” an intriguing concept introduced by Bowker (2005).
Revisiting the foundations of information discovery and access systems
Authors: Buckland Michael , Greenberg Jane , La Barre Kathryn , Palmer Carole 
Published: February 2009

AbstractEach year, the pace of building digital resource and data repositories increases. Multiple challenges face each project, for which no adequate technological solution may exist. The focus of this panel moves beyond construction to address the question: What assumptions and principles lie beneath the technology scaffolding digital environments? The members of this panel are engaged in open exploration and reconsideration of the roles played by representational and organizational structures that seek to support, and which sometimes impair discovery, access and use. These structures take shape in metadata, vocabulary and classificatory frameworks. Specific topics covered will include heritage classificatory work well‐suited for application in digital environments, an inversion of the role of metadata as infrastructure for documents, application of bibliographic relationship taxonomies such as FRBR in tracking the life cycle of data objects, and potential definition and organizational roles to be played by collection level representations.
Internet/computer addiction among juveniles in Turkey
Authors: Ozmutlu Seda , Ozmutlu H. Cenk , Spink Amanda 
Published: February 2009

AbstractInternet and computer addiction has been a popular research area since the 90s. Studies on Internet and computer addiction have usually been conducted in the US, and the investigation of computer and Internet addiction at different countries is an interesting area of research. This study investigates computer and Internet addiction among teenagers and Internet cafe visitors in Turkey. We applied a survey to 983 visitors in the Internet cafes. The results show that the Internet cafe visitors are usually teenagers, mostly middle and high‐school students and usually are busy with computer and Internet applications like chat, e‐mail, browsing and games. The teenagers come to the Internet cafe to spend time with friends and the computers. In addition, about 30% of cafe visitors admit to having an Internet addiction, and about 20% specifically mention the problems that they are having with the Internet. It is rather alarming to consider the types of activities that the teenagers are performing in an Internet cafe, their reasons for being there, the percentage of self‐awareness about Internet addiction, and the lack of control of applications in the cafe.
Collection‐level user searches in federated digital resource environment
Authors: Zavalina Oksana 
Published: February 2009

AbstractAs part of a federation project providing integrated access to over 160 digital collections, we are studying how collections can best be represented to meet the needs of diverse user communities. This paper reports preliminary transaction log analysis results from that project on subject representation of the digital collections. The findings reveal prevalence of the broadly defined subject search at the collection level, and the lack of semantic similarity between the user queries and the GEM controlled vocabulary terms used for collection description. Based on the actual search data, it is recommended that the 2nd group of entities in the FRBR model be updated to cover ethnic/national groups and classes of persons. The paper proposes definitions of the two major collection‐level search types ‐ known‐item and subject ‐ and formulates research questions for further investigation into subject access to federated collections.
End‐user collection building behavior in Flickr
Authors: Stvilia Besiki , Jörgensen Corinne 
Published: February 2009

AbstractThis article analyzes photoset and group naming conventions in Flickr to gain insight into the collection building behavior of Flickr users. It appears that individual user photosets are focused more on the components of the user's context and evolve from the bottom‐up based on selected shared attributes of the user's photos. Group collections, on the other hand, seem to be organized more around general concepts or discussions of group members' work and constructed top‐down by matching the photo attributes to the purpose of the group. The article identifies ten categories of attributes that users might use for forming digital photo collections and compares these to earlier research.
Can I email this? The use restrictions found in licensed digital resources
Authors: Eschenfelder Kristin R. 
Published: February 2009

AbstractRecent digital library research has raised concerns about how use restrictions, such as limits on printing or emailing, may affect licensed digital resource usability. This paper describes the results of a study to investigate the types of technological protection measure (TPM) based use restrictions that authorized users of licensed scholarly resources experience when making typical use of licensed resources. Data collection involved a use based assessment of a sample of resources from engineering, health sciences and history/art history. Analysis developed a framework of observed TPM. The framework distinguishes between “hard” and “soft” TPM and identifies 6 subtypes of soft TPM including extent of use, frustration, obfuscation, omission, decomposition, and threat. The study concludes that soft TPM are common in licensed scholarly resources and while hard TPM are less common, they are not unknown. The framework provides a vocabulary to distinguish between different types of use restrictions and to therefore test which use restrictions may create more usability problems.
ChatterCrop: Reaping the benefits of online product reviews
Authors: Sharma Nikhil , Khopkar Tapan , Otterbacher Jahna 
Published: February 2009

AbstractWeb 2.0 has allowed online shoppers to become not just information seekers but also information providers. Many e‐commerce venues allow users to share their experiences in the form of textual product reviews. While textual product reviews represent a wealth of information for candidate buyers, finding pertinent information becomes difficult, as the number of reviews for a particular product becomes large, or if the buyer is interested in particular features of an item. We present ChatterCrop, a tool that uses text summarization. ChatterCrop condenses the information from a large set of reviews into a few sentences, and allows users to customize these summaries for feature‐focused search. In a user study, subjects used ChatterCrop and a sortable list of reviews, to answer questions about two camcorder models. When looking for information about particular features, ChatterCrop outperformed the list, in terms user confidence and perceived ease in finding pertinent information. ChatterCrop's summaries also provided users with starting points to guide further research, and were particularly helpful in the early stages of sensemaking.
Query expansion: Internet mining vs. pseudo relevance feedback
Authors: Roussinov Dmitri , Muresan Gheorghe 
Published: February 2009

AbstractWe report an investigation of techniques for mining world wide web in order to identify terms (single words or phrases) that are highly related to a topic (query) described by a short (one sentence or a paragraph‐long) interest statement. These terms are subsequently used to improve automated document retrieval. By following a standard testing methodology, we established that our technique improves the effectiveness of retrieval up to 8% over BM25 combined with pseudo‐relevance feedback, which is currently known to be one of the best ranking functions, and was indeed the strongest baseline in our studies
How incorrect information delivers correct search results: A pragmatic analysis of queries
Authors: Lee Jin Ha , Renear Allen 
Published: February 2009

AbstractAlthough the accuracy of the information relied on in formulating known‐item search queries is generally regarded as critical to the search success of those queries, it has been observed that in some cases, such as music information retrieval, searching is often successful even when the information the queries are based on is flawed. Resolving this puzzle is important to a comprehensive understanding of information seeking in general and, perhaps, the success of new social indexing strategies in particular. One promising source of insight is the area of linguistics known as pragmatics. We show how a particular concept from pragmatics, the attributive/referential distinction, can illuminate how queries can function effectively independently of the apparent accuracy of the information they seem to rely on. This suggests possible new directions for the development of more effective information retrieval systems.
Spatial perception of blind people by auditory maps on a tablet PC
Authors: Jeong Wooseob 
Published: February 2009

AbstractAlthough a tablet PC is designed mainly for sighted people, there are potential applications for the blind. An auditory map system for the blind is proposed as one of the applications on a tablet PC. The proposed application requires no additional devices or software other than a table PC, which would be a cheap alternative to expensive existing tools for the blind people. With the frame work of dimensionality from geography, point‐line‐area, more systematic testing is conducted with 20 totally blind people, to provide valuable information about the potential implementation of an auditory interface on a geographic information system for the blind. Moreover, since the participants are totally blind and the number of them is much more than other research on the blind, it will provide more valid information and conditions necessary for the implementation.
Tagging the tags… Process, observations and analysis of conversations in metatagging at an ASIST interactive poster session
Authors: Graham Jennifer E. , Abbas June M. 
Published: February 2009

AbstractResults from a 2006 ASIST poster session on tagger's motivations are presented. Researcher's conducted short conversations with conference participants as they viewed the researchers' poster and tagged its contents. Using a content analysis method, researchers' conversations with participants were analyzed. Content analysis revealed six broad themes or “clusters” of interest: 1) General, 2) Observations, 3) Specific Uses/Suggestions, 4) Curricular, 5) Concerns and 6) Opportunities/Potentials. Within those clusters various specific points were ranked by frequency of occurrence. Overall findings indicate the ASIST community is interested in seeing what happens with this phenomenon, but voiced very real concerns about the longevity of tagging, specific uses in scholarly environments, and the effect it will have on annotation, bibliographic, and subject analysis.
Changes in cortically induced inhibition in amyotrophic lateral sclerosis with time
Authors: Attarian Shahram , Pouget Jean , Schmied Annie 
Published: February 2009

AbstractChanges in intracortical inhibition have been detected by means of paired‐pulse transcranial magnetic stimulation (TMS) based on electromyographic recordings in many neurological or psychiatric disorders, including amyotrophic lateral sclerosis (ALS). By contrast, inhibitory responses have been generally overlooked in single motor unit (MU) studies in patients with ALS. The aim of this study was to investigate the TMS‐induced inhibitory responses of single MUs in peristimulus time histograms and the changes observed with time. For this purpose, 263 MUs were tested in 10 ALS patients in two to four recording sessions. Upon subdividing the data into epochs corresponding to mean disease durations of 12, 20, 32, 43, and 168 months, we found that inhibitory responses occurred more frequently than normal throughout the course of the disease and were stronger than normal during the first year after disease onset. This finding argues against the hypothesis that loss of inhibition may be part of the pathogenic process in ALS. Muscle Nerve 39: 310–317, 2009
A novel mutation in the VCP gene (G157R) in a german family with inclusion‐body myopathy with paget disease of bone and frontotemporal dementia

Published: February 2009

AbstractMutations in the valosin‐containing protein (VCP) are known to cause autosomal‐dominant inclusion‐body myopathy with Paget's disease of bone and frontotemporal dementia (IBMPFD). We report a novel missense mutation (G157R) in the N‐terminal region of the VCP gene in a German family. Family members presented with mild to moderate proximal muscle weakness, Paget disease of bone, and signs of early cognitive decline, with onset in the fourth decade. Two family members also showed signs of early hearing impairment, which was confirmed to be sensorineural in one person, a symptom not yet described in the context of IBMPFD.

Finite element formulation for poroelastic problem with zero effective stress boundary condition
Authors: Xu Bin , Wong Ron C. K. 
Published: February 2009

AbstractZero effective stress boundary condition along with constant fluid flux is commonly encountered in geotechnical applications such as uncased borehole stability, fluid injection and production at an uncased borehole, hydraulic fracturing and sand production. This complex boundary condition introduces high nonlinearity in the numerical simulation. Conventional iterative methods such as Newton–Raphson method are required to solve this nonlinear problem iteratively, which involve huge computing time and also pose numerical difficulties on the convergence. To overcome this numerical difficulty and hence reduce the computing time, a novel numerical technique is proposed in this paper. Its performance is evaluated using a numerical example simulating fluid injection around an uncased borehole. Copyright © 2009 John Wiley & Sons, Ltd.

AbstractBackgroundMultidrug resistance is a key factor for the sobering outcome of relapsed and metastatic human hepatoblastoma (HB). Gene directed treatment approaches were recently identified as possible treatment options against advanced HB, in which standard chemotherapy regimens are partially insufficient. The aim of this study was to systematically analyze the effects of suicide gene therapy in three HB cell lines using a yeast‐derived cytosine deaminase (YCD)‐combined yeast uracil phosphoribosyltransferase (YUPRT)‐based adenovirus‐mediated gene transfer.ProcedureYCD and YUPRT were fused to form the bifunctional suicide gene SuperCD. Adeonoviral vectors were used for transduction. Tumor cells transduced at MOI 50 were incubated with 5‐fluorocytosine (5‐FC) in ascending concentrations.ResultsTransduction rates were 87.8% (+6.7) in the mixed HB cell line HUH6, 98.6% (+1.4) in the epithelial HB cell line HepT1 and 93.6% (+0.6) in the multifocal HB embryonal cell line HepT3, respectively. In HepT3 and HepT1 cells suicide gene therapy with SuperCD/5‐FC was highly effective leading to HB cell damage far above those of application of the prodrug 5‐FC only. In HUH6 cells the approach had no effect due to a lack in activity of the CMV promoter being employed for transcription of the SuperCD transgene.ConclusionAssuming employment of fully active promoters, the SuperCD/5‐FC approach may serve as a potentially useful anti‐tumor strategy against advanced HB.

Handover prioritizing scheme for reducing call failure probability in cellular wireless network
Authors: Garah M. , Benatia D. 
Published: February 2009

AbstractThis paper proposes a scheme suitable for managing handover in wireless cellular network. The main objective of the proposed scheme is to reduce the probability of forced termination of ongoing call due to handover failure. The scheme employs a queuing discipline, and the priority of queued is based on the residual time of the mobile user in the overlap region between two adjacent cells, assuming that the user's location and speed can be determined, then we applied the ascending priority; it means that the users having a shorter residual time join the head of the queue (i.e., high priority) while those having longer residual time at the end of the queue (i.e., low priority). Fixed channel allocation strategy (FCA) is employed and simulation results obtained concern: call blocking probability (CBP), handover failure probability, and average waiting time in the queue. Also simulation results are compared to those obtained by: non‐prioritized scheme (FCA), and FCA queuing with FIFO discipline. Results show that our proposed method decreases significantly handover failure probability compared with other two schemes. Copyright © 2009 John Wiley & Sons, Ltd.
