Topographical distribution of cerebral cortical thinning in patients with mild Parkinson's disease without dementia
Authors: Lyoo Chul Hyoung , Ryu Young Hoon , Lee Myung Sik 
Published: January 2010

AbstractThe pathology of Parkinson's disease (PD) is not confined to the brainstem regions, but spreads to involve the neocortical areas. Using surface‐based cortical thickness analysis, we studied the topographical distribution of cortical thinning in nondemented patients with mild PD. The high‐resolution magnetic resonance imaging (MRI) studies were performed in 48 patients with PD without dementia and 56 age‐matched healthy controls. Using the Freesurfer software, surface‐based analysis was done to find changes in cerebral cortical thickness in patients with PD. Compared to the controls, patients with PD showed significant cortical thinning in the temporal, inferior parietal, rostral frontal, and orbitofrontal cortical areas. Thinning of the cerebral cortex occurs even in nondemented patients with mild PD, and its topographical distribution was similar to that of the neocortical Lewy bodies. Further studies are needed to find pathological and clinical correlates of thinned cerebral cortex found in nondemented patients with mild PD. © 2010 Movement Disorder Society

AbstractParkinsonism in cerebrotendinous xanthomatosis (CTX) is rare. There are no published studies with imaging findings of dopamine transporter using 99mTc‐[2‐[[2‐[[[3‐(4‐chlorophenyl)‐8‐methyl‐8‐azabicyclo [3,2,1] oct‐2‐yl] methyl] (2‐mercaptoethyl) amino] ethyl] amino]‐ethanethiolato(3‐)‐N2,N2,S2,S2]oxo‐[1R‐(exo‐exo)] (99mTc‐TRODAT‐1) SPECT in CTX patients. This report is on the clinical details of five genetically‐proven CTX patients (two with and three without parkinsonism). Imaging findings using cranial magnetic resonance (MR) imaging and 99mTc‐TRODAT‐1 SPECT are also shown. Clinical correlation of neuroimaging findings and clinical presentations was made. A literature review of the clinical and neuroimaging features of eight CTX patients with parkinsonism reported in the English literature is also presented. The parkinsonian features of our two cases and the other eight reported cases occurred before the age of 50 years. The MR imaging study showed variable findings, in which, besides the common diffuse cerebral and cerebellar white matter lesions shown in CTX, several focal brain lesions were also noted. Of the focal lesions, substantia nigra abnormalities were seen only in the two cases with parkinsonism. The 99mTc‐TRODAT‐1 SPECT study showed different degrees of unilateral or bilateral abnormalities in the striatal binding in both visual and semiquantitative assessments. parkinsonism can be one of the neurologic presentations of CTX. Even though abnormal findings of the substantia nigra were detected in both of our CTX patients with parkinsonism, basal ganglion lesions have not been uniformly described in MR imaging findings of reported CTX patients with parkinsonism. 99mTc‐TRODAT‐1 SPECT study can be of value in the detection of striatal involvement, and the study results also suggest pre‐synaptic dopamine neuron involvement in CTX patients with parkinsonism. © 2010 Movement Disorder Society
Information system design for communication: The use of genre as a design element
Authors: Feinberg Melanie 
Published: January 2010

AbstractAn information system is not merely a container for documents; through the ways that resources are selected, organized, and made available to users, information systems themselves work as expressive media, enabling the communication of a specific point of view on the collected materials. By analyzing information systems themselves as documents, we can better understand how information systems communicate these perspectives more and less persuasively, and we can use this understanding to facilitate the design of information systems for communicative purposes. This study examines one communicative mechanism available to information systems: the selective adaptation of genre conventions. Using theories of genre developed in rhetoric, composition, and applied linguistics, I show how two systems for organizing information, the Prelinger Library and the Warburg Institute classification, exhibit deviations from typical genre conventions for libraries, and I show how these deviations work as rhetorical tools to facilitate effective communication. I then demonstrate, using the creation of a prototype, how this understanding of genre as a communicative mechanism for information systems might be translated into the design context. By creating designs that incorporate an enhanced conceptual grasp of genre and other rhetorical properties of information systems, we can facilitate the construction of information systems that systematically and purposefully communicate original, creative points of view regarding their assembled collections, and so enable learning, discovery, and critical engagement for users.
Evaluating a metadata‐based term suggestion interface for PubMed with real users with real requests
Authors: Tang Muh‐Chyun , Wu Wan‐Ching , Hung Bang‐Woei 
Published: January 2010

AbstractThis paper reports results of an evaluation study of MAP (Multi‐faceted Access to PubMed), a metadata induced query suggestion interface for PubMed bibliographic search.A novel evaluation methodology was used to address the challenges involved in evaluating an IIR (Interactive Information Retrieval) system such as the MAP interface. The most significant aspect of this methodology is that, instead of using assigned tasks common in traditional IR evaluation, it asks real users with real search requests to search with real systems in an experimental setting. Several performance measures were created based on which comparisons were made between MAP and PubMed baseline. MAP was shown to perform better in several of these measures, especially when the search requests had not been attempted before.The finding pointed to search characteristics as an important intervening variable in IIR evaluation. The advantages of and potential threats to our methodology were also discussed.
Introducing a cognitive methodology for the automated detection of connotative meaning in text
Authors: Snyder Jaime , D Michael A. , Yilmazel Ozgur , Liddy Elizabeth D. 
Published: January 2010

AbstractPilot results are used to illustrate the potential of an integrated multi‐disciplinary approach to semantic text analysis that combines cognitive‐oriented human subject experimentation with Machine Learning (ML) based Natural Language Processing (NLP). The goal of this work is to automate the recognition of connotative meaning in text using a range of linguistic and non‐linguistic features. This methodology combines human evaluations of text with automated processing of text in order to address social, cognitive and linguistic aspects of connotative meaning. The design of this study places the human in the loop at the point of identifying the degree of connotation present within a given text, rather than at the point of expert linguistic analysis. Findings from the pilot study show that consensus between human subjects regarding the presence of connotative meaning in text can be achieved, that the degree of connotation present in a given text can be described on a continuum, and that a system can be implemented to recognize extreme cases of connotation (or its opposite, denotation). The protocol used in this pilot study was run using a relatively modest number of human evaluators and set of data. Based on the extensibility of methodology and the promising findings described here, the reliability of the data used to train the ML system can be easily improved by increasing the size of both the human subject sample and the data set.
Mapping library and information science: Does field delineation matter?
Authors: Zhao Dangzhi 
Published: January 2010

AbstractTraditional field delineation methods in bibliometric studies appear to have reached their limits when dealing with highly interdisciplinary fields such as nanotechnology or stem cell research which have recently become a focus of science and technology policy research. Researchers therefore have developed sophisticated algorithmic procedures to overcome these difficulties, hoping to collect a set of articles in a research field being studied that is complete as well as clean. The present case study explores the effect of field delineation on author co‐citation analysis (ACA) studies of the intellectual structure of the library and information science (LIS) field using two different but overlapping journal sets to define the LIS field. We find that the major overall structure remains largely the same between these two views of the LIS field, which suggests that field delineation is not crucial to ACA studies of research fields, provided the emphasis of a study is on the major overall structure of a research field. The two views do however differ at a more detailed level of analysis, which suggests that studies that aim to shed light on particularly subtle research policy issues may need to pay serious attention to the way that they delineate their fields.
Incidental exposure to online news in everyday life information seeking context: Mixed method study
Authors: Yadamsuren Borchuluun 
Published: January 2010

AbstractThe Internet and new technologies are changing news reading habits and information behavior of readers. News readership is shifting to the Internet because of accessible, inexpensive technology, and free content. The prevalence of news on the web provides opportunities for people to encounter news in an incidental way as a byproduct of their online activities. This poster presents the preliminary results of the dissertation study on incidental exposure to online news, which was conducted in the spring of 2009.
A “pink” key to information grounds
Authors: Kelder Jo‐Anne , Lueg Christopher 
Published: January 2010

AbstractThe color pink plays a crucial role in breast cancer awareness information delivery as the “pink ribbon” is established as an international symbol of breast cancer awareness. One commonly understood purpose of using a specific color is related to the marketing concept of “brand recognition”: instant recognition of the messenger and also the message. In this paper we look at the role of color from a different, yet under‐researched perspective. We argue that in the real world of breast cancer community education work, the color pink also functions as an agent that helps establish dynamically created “information grounds”. The discussion of this novel perspective on information grounds is informed by a 12 month ethnographic case study describing and analyzing community education work in the context of breast cancer awareness information delivery.

Library and information center accessibility: The differently‐able patron's perspective
Authors: Copeland Clayton 
Published: January 2010

AbstractThe 1980's “Decade of the Disabled,” stimulated increased awareness regarding rights of differently‐able people for better access to education, employment, and information (United Nations, 1982). As “great equalizers of knowledge,” (Epp, 2006) libraries and information agencies were among organizations striving to become accessible, enabling environments for their differently‐able patrons. While “diversity” remains a critical focus for libraries and information agencies, many remain inaccessible for the differently‐able (Murray, 2000, 2001; Wojahn, 2006). In recent years, few research studies have investigated how library – physical and virtual – accessibility might be improved.The purpose of this study is to understand library services and accessibility in public and academic libraries from the differently‐able patron's perspective. Recognizing the marginalization and disenfranchisement that can be experienced by diverse and differently‐able individuals, this study investigates information center accessibility and services for such populations. The research identifies differently‐able patrons in a variety of communities and the information professionals serving them. Through a series of interviews and focus groups with these individuals, this study explores “lived experiences” of these groups to understand how library accessibility / inaccessibility may contribute to the social construction of disability within these contexts. Specifically, it investigates the impact of social constructivism and technological advances upon library accessibility and services. Ultimately, the study's goal is to illuminate issues related to library accessibility / inaccessibility and services in public and academic libraries. Through participants' voices, the results of the study are expected to suggest how library accessibility and services may be improved. Findings may also suggest strategies that libraries and information centers may employ to help patrons overcome challenges related to technology skill development and unemployment.
Patient, heal thyself! Advocating for accessible healthcare websites
Authors: Brobst John 
Published: January 2010

AbstractThe purpose of this research is to examine healthcare websites to determine their current level of accessibility based on the criteria established in Section 508 of the Rehabilitation Act of 1973. Web accessibility refers to providing equal access to the Internet and equal opportunity to use the Internet for people with disabilities. The unique value of this investigation lies in the attempt to identify what interventions could serve to improve the observed levels of website accessibility in healthcare websites.Federal public laws demonstrate a concern for assuring equal rights and access for those with disabilities. However, the intent of the laws, being to achieve accessibility, has not been accomplished. Recent studies have shown that most categories of websites have low accessibility levels. If allowed to continue, the failure to make accessibility a reality could result in the disenfranchising of a major segment of society.The goal of this study is to determine what can be done, realistically and pragmatically, to make healthcare websites within the United States more accessible. The approach will be a multi‐method examination of accessibility involving: policy analysis, online survey, expert testing, automated testing, and accessibility testing. Each method will add a unique value to the study and in combination will provide a fuller and richer understanding of the current status of healthcare website accessibility. The multi‐method approach supports the Action Stance taken in designing this study. This Action Stance approach focuses on designing research efforts that lead to effective and positive change.For this study, the positive changes will include developing a set of best practices towards attaining web accessibility, identifying interventions that promote accessibility, and making recommendations for improving the federal information policies that address website accessibility.
Transdisciplinarity and information science in earth and environmental science research
Authors: Allard Suzie , Allard Grant 
Published: January 2010

AbstractThis poster addresses the theme of the conference “Thriving on Diversity‐ Information Opportunities in a Pluralistic World” by discussing transdisciplinarity and what this paradigm means to librarians and information scientists. Transdisciplinary research is a means to address research problems, especially those in complex systems (Hirsch Hadorn et al., 2008). The role of transdisciplinary research in earth and environmental sciences is explored, with particular attention to the challenges for information science researchers and professionals. Complex and global questions such as climate change may be best addressed using a transdisciplinary approach making the collaboration between scientists and information professionals more important. This collaboration is explored in relationship to DataONE (Observation Network for Earth), an NSF funded cyberinfrastructure project that supports the full data lifecycle for scientists in the diverse domains that are embodied in the earth and environmental sciences.

Data management and curation of research data in academic scientific research environments
Authors: Hayes Barrie , Harroun James , Temple Brenda 
Published: January 2010

AbstractThe Structural Bioinformatics Core Facility at the University of North Carolina at Chapel Hill (SBI Core) assists researchers university‐wide in computational structural biology techniques and incorporating structural biology/bioinformatics into their grants and publications. The SBI Core works with a diverse population of researchers from numerous departments and provides support to an ever‐changing body of research. The computational biology services provided by the SBI Core are data‐intensive and use a diverse and distributed set of applications for processing, data storage, and data management.As the amount of data and number of projects have increased, the SBI Core requires an effective strategy for managing data and facilitating data sharing between the SBI Core and the researchers it assists. The UNC‐CH Health Sciences Library (HSL) has begun a collaborative project with the SBI Core to identify the crucial data management needs and to envision new roles for the library in e‐science and data management. In partnership, the SBI Core and the HSL have identified major obstacles in data sharing, data management, and data access. Furthermore, the SBI Core and the HSL will develop solutions in which the library facilitates collaboration among campus resources and matches unmet needs to external resources. One of the library's goals in this proof‐of‐concept project with the SBI Core is to become a central campus resource for research support and data management.

Espoused theories and theories‐in‐use of information literacy: A model for reflection and evaluation
Authors: Kerr Paulette 
Published: January 2010

AbstractWhat values and frameworks underpin professional practice in information literacy education? Is practice aligned with mission and goals?The poster documents the preliminary findings of a research study which investigates the relationships between espoused theories and theories‐in‐use of information literacy (IL). The study asks if and how, the foundational beliefs and values of information literacy as expressed in official policy documents including mission statements in academic libraries (espoused theories), guide and are realized in the practice of information literacy in these institutions (theories‐in‐use). The research is guided by the theoretical framework of Argyris and Schön (1974), theory of action, in which contrasting theories, namely espoused theories and theories‐in‐use are used to examine professional practice.The poster highlights the process and findings of the in‐depth analysis of one library's policy statements and online tutorial, which employed a comparative questioning approach (Strauss and Corbin, 1998). The analysis uncovered statements and concepts relating to teaching and learning outcomes which were labeled, compared, and grouped into broad categories and emergent themes. The findings indicate varying patterns of congruence and incongruence between the library's espoused theories and theories‐in‐use of information literacy.The research is presented as a model for reflecting on and evaluating tools of practice in information literacy education.
Navigating one million tags
Authors: Gwizdka Jacek , Bakelaar Philip 
Published: January 2010

AbstractWeb 2.0 users engage in collaborative tagging and associate words with the users' own and with other users' content. The result is an additional layer with descriptions of web resources. The information contained in the tag‐resource associations can certainly be useful. However, we argue that current collaborative tagging systems do not support users well in navigating and exploring tag spaces, because tags are treated as independent. We suggest that different ways of displaying tags to users are needed and describe our approach to supporting users in navigating tag spaces. We illustrate our ideas with a prototype user interface.

AbstractThis study investigates the status of personal information management (PIM) in the library and information science curriculum. Although there has been increased interest in PIM research over the years, it is unclear how that research has affected pedagogy. Methods include analysis of PIM courses and a survey of researchers to assess their ideas and attitudes about what should be taught.
Comment centric news analysis for ranking
Authors: Liu Xiaozhong 
Published: January 2010

AbstractRanking documents to feed users' information need is a challenging task, due to the dynamic nature of users' interests with respect to a query, which changes from time to time. In this paper, I will propose the innovative method to extract a real‐time language model estimation of the community interest given a query from, and use this model to rank retrieved documents. In this experiment, user comments tagged news (by using passage retrieval algorithm) collection is employed to represent community. The interest based ranking is differing from traditional relevance based ranking.
