Alterations of TMEM16a allostery in human retinal microarterioles in long‐standing hypertension
Authors: Gui Dongmei , Li Yanfeng , Chen Xiaolong 
Published: April 2015

AbstractWe hypothesized that the calcium‐activated chloride channel (CACC) transmembrane member 16A (TMEM16A) ionic mechanism may be a general mechanism in remodeling of vascular smooth muscles, including the retina. These vascular remodeling may have a critical impact on retinal ischemia during chronic hypertension. In this study, we examined TMEM16A protein interactions with calmodulin and CaMKIIδ likely cause efflux of chloride, thus resulting in increased vascular resistance by increasing vascular wall tone in long‐standing hypertension. Control experiments were performed in static concentrations of calcium and using the specific TMEM16A inhibitor T16Ainh‐A01 [2‐[(5‐ethyl‐1,6‐dihydro‐4‐methyl‐6‐oxo‐2‐pyrimidinyl)thio]‐N‐[4‐(4‐methoxyphenyl)‐2‐thia zolyl]acetamide]. The results of our study provide preliminary evidence that CACC shows altered pharmacologic and biochemical properties in retinal vessel in long‐standing hypertension.© 2015 IUBMB Life, 2015 67(5):348–354, 2015
Curation and policy issues in collaborative research data management communities: Perspectives from key stakeholders
Authors: Luesebrink Michael , Huang Hong , Bogdan Kristin , Salo Dorothea , Thomas Charles , West Jevin , Wilson Lizabeth (Betsy) 
Published: April 2015

ABSTRACTThe explosion of scientific data in recent years has resulted in the need to compile, store and globally share this research information with the multi‐disciplinary communities of science. This has resulted in research data management communities that are responsible for curating data within institutional repositories. This panel is sponsored by the SIG Scientific and Technical Information to initiate a discussion addressing data curation issues as they pertain to collaborative research data management communities within the current institutional research environment from the perspective of key stakeholders. The panel objective encompasses an examination of contemporary curation practices and data management policy issues that impact the initiation and implementation of research data management plans for scientific researchers. In addition it will explore the role that institutional repositories play in the extraction, preservation, and storage of research data while providing access to data sharing in the global scientific research communities. The panel will be comprised of key institutional stakeholders, which include university administrators, information professionals, and research scientists.
Public places, private lives: Balancing of privacy and freedom of expression in the United Kingdom
Authors: Newell Bryce Clayton 
Published: April 2015

ABSTRACTThe rights of privacy and expression often conflict. Case law from the United Kingdom suggests that the incorporation of the European Convention on Human Rights into domestic law has spurred the growth of domestic privacy law at the expense of the rights of the press to free expression and, in line with prior theory, has also granted greater political authority to courts and judges tasked with balancing privacy and expression in domestic legal disputes. These shifts in privacy case law may also suggest that incorporation has increased opportunities for participatory democratic governance by the citizenry, at least through enhanced access to judicial remedies for privacy violations and the enforcement of Convention rights, as interpreted by the European Court of Human Rights.
Dealing with the long tail: Providing uniformity to compound tags
Authors: Syn Sue Yeon 
Published: April 2015

ABSTRACTIn using social tags, it has been a challenge to deal with the long tail of the tag distribution. A good portion of tag distribution includes compound tags. Based on the observation that the various forms of compound tags exist in a tag data set, this study tests a way to process various compound tag forms into a uniformed form. The tag uniformity process is introduced with the decomposition algorithm by identifying forms of compound tags. With the tag uniformity process, this study explores the potential of better use of social tags by reducing tag noise and shortening the long tail of the tag distribution. In addition, it is expected that the uniformity process will enhance the effectiveness of the measurements for tag use such as tag frequency. The results demonstrate that the tag uniformity process can successfully shorten the long tail and make the tag frequency precise as a measurement. Although the uniformity process may not solve all the issues related to the long tail, it can be implicated for improving tag analysis and services using tags. The benefits and limitations as well as potential implications of the tag uniformity process for tag analysis and use are discussed.
File synchronization and sharing: User practices and challenges
Authors: Capra Robert , Vardell Emily , Brennan Kathy 
Published: April 2015

ABSTRACTIn this paper, we present results of qualitative analysis of interviews with 16 university faculty regarding their use of file synchronization and sharing technologies in their work and personal lives. We identify key problems and considerations that influence file synchronization and sharing practices, and describe commonly used strategies. Our findings show that while behaviors have evolved as technology changes, users continue to make extensive use of familiar patterns of access, including automated and manual methods. We identified several factors that influence users’ choice of methods for synchronization, including privacy and security concerns, data size, institutional policies, and knowledge of systems. We present insights about how boundaries and data separation affect synchronization practices, and about specific synchronization issues users faced when collaborating. Our findings extend research on personal and group information management practices and provide insight for the design of synchronization and sharing systems.
The karamanlidika digital library project: Connecting karamanlides memories
Authors: Aytac Selenay 
Published: April 2015

ABSTRACTThe purpose of this paper is to outline how an international initiative to connect Karamanlides cultural heritage could be pursued by using digital library technologies. The Karamanlides, also known as the Karamanli people, are those who spoke Ottoman Turkish and wrote in Greek characters in Asia Minor (Anatoli) during the rule of the Ottoman Empire. The first step of the research was to identify the available digital Karamanlides cultural artifacts via social media tools and pinpoint the useful metadata. The next step focused on the analysis of these user generated metadata derived from user uploaded images. Findings suggested that these unique cultural artifacts have been scattered all over the World Wide Web and lack descriptive metadata. Conceptual framework for the proposed digital library project will be discussed.
Exploring alternativity of institutional repositories to subscription resources based on users’ accesses log
Authors: Chen Kuang‐hua , Huang Chien‐chih 
Published: April 2015

ABSTRACTInstitutional repository (IR) has been widely deployed in a lot of universities and research institutions. Researchers all over the world share their research outputs in an open‐access way. Not only does it speed up the dissemination of scholarly information, but it can also decrease the cost in acquiring commercial databases. This article investigates whether IRs are the viable alternative to subscription resources. The primary result shows that the satisfaction rate is 8.255% based on 124,357 real users’ experiences. Furthermore, the different institutional repositories demonstrated their capability to complement each other in fulfilling the users’ access requests. The promising end result suggests that future studies should include more types of open‐access repositories.
Identifying search patterns in an image‐based digital library
Authors: Han Hyejung , Wolfram Dietmar 
Published: April 2015

ABSTRACTThree months of clickstream transaction log data for an image‐based digital library were analyzed for patterns in user session behavior. After extensive log cleaning of the data files, k‐means cluster analysis was applied using selected session‐related statistics. The outcomes reveal largely uniform session behaviors (97.37%) consisting of a limited number of actions, with a higher number of queries than other session types, but little browsing of individual results. Given the specialized nature of the digital collections within the studied system, most searchers appear to engage in purposeful, directed searching. The remaining session clusters represent higher degrees of browsing over a longer time with fewer queries per session. The session behaviors for this environment are markedly different than those revealed by transaction log studies of other information retrieval environments.
Exploring cultural differences in language usage: The case of negation
Authors: Stoytcheva Svetlozara , Cohen Dov , Blake Catherine 
Published: April 2015

ABSTRACTPrior research suggests that speakers of Asian languages are more likely to use negation than English speakers. Our goal in this work is to explore this theory using empirical data from news stories. Specifically, we used natural language processing to compare negation usage in two newspapers: the New York Times and Xinhua News (English Edition). Overall, negation represents 0.55% of typed dependencies in the New York Times (versus 0.18% in Xinhua News). Additionally, 9.28% of sentences and 86.56% of articles in the New York Times contain one or more instances of negation (compared to 3.33% of sentences and 24.94% of articles in Xinhua News). In contrast to the prevalent theory, negation is approximately three times more common in the New York Times than in Xinhua News (English Edition).
Data narratives: Increasing scholarly value
Authors: Pouchard Line , Barton Amy , Zilinski Lisa 
Published: April 2015

ABSTRACTData narratives or data stories have emerged as a new form of the scholarly communication focused on data. In this paper, we explore the potential value of data narratives and the requirements for data stories to enhance scholarly communication. We examine three types of data stories that form a continuum from the less to the more structured: the DataONE data stories, the Data Curation Profiles, and the Data Descriptors from the journal Scientific Data. We take the position that these data stories will increase the value of scholarly communication if they are linked to the datasets and to the publications that describe results, and have instructional value.
Closing the app gap: From plan to project I
Authors: McDowell Kate , Stevenson Deborah , Mabbott Cass 
Published: April 2015

ABSTRACTOur Closing the App Gap research project, examines the use of tablets, apps, and e‐books in public libraries as a tool against summer reading loss in primary‐grades children in underserved communities. Children in low‐income families are less likely to meet important reading milestones, and they are particularly likely to suffer from summer reading loss, the setback of skills over the long summer vacation. As we already know, this loss can be addressed by summer reading programs in public libraries.Additionally, as digital media grows in importance, the resource disparity between affluent families and lower‐income families becomes even more pronounced, with a digital divide effect that shapes the experience of emergent readers. One 2011 study indicated that 55% of children eight and younger from families earning $75k or more per year have access to a smartphone, iPod/phone, or tablet, while in families earning $30,000 or less, only 22% of children have similar access. With apps a growing part of the educational landscape, increased access is advantageous.This approach brings new tools in the fight against summer reading loss, enhances technological literacy, and mitigates the effect of the digital divide on children in lower‐income families. Our poster will discuss the various aspects of our research, including: our greatest challenges, the creation of a model that can help other public libraries use apps and tablets with children, our proposed multi‐site project that builds on what we've learned, and the potential ramifications of closing the digital divide and improving literacy for every child.
Connecting collections and cultures by creating a community of children's librarians around early literacy storytimes
Authors: Campana Kathleen , Brouwer Marin , Urban Ivette Bayo , Mills J. Elizabeth , Capps Janet , Feldman Erika , Burnett Kathleen 
Published: April 2015

ABSTRACTCommunities of practice are important tools for professional development, encouraging peer‐to‐peer learning and knowledge creation. This study, which is part of a three‐year Institute for Museum and Library Services National Leadership Research Grant, examined children's librarians’ perceptions of a community of practice they created during an extended online, interactive training program. The librarians shared both positive and negative perceptions of the community that was created during the training. Through the interviews it became apparent that while creating a community of practice the librarians made connections between their collections and shared their library cultures.
Understanding what personal information items make categorization difficult
Authors: Oh Kyong Eun , Belkin Nicholas J. 
Published: April 2015

ABSTRACTThis study examined personal information items that are difficult to categorize, and how people deal with these information items. For this research study, 18 participants were asked to keep a diary over a week and record diary entries whenever they decided to save or organize any electronic personal information items. Then, two post‐diary semi‐structured interviews were conducted to ask questions about how they organized their information items and why they made such decisions based on the diary they kept. Interviews were analyzed by using a grounded theory approach. The results show that the information items that are ambiguous or anomalous are difficult to categorize. Participants dealt with ambiguous or anomalous information items by categorizing them into one of their existing categories, placing them into a miscellaneous category or revising the existing organizational structure. Since personal information items that are difficult to categorize directly influence the time and effort needed to organize personal information, it is important to understand what kind of personal information items makes personal information organization difficult. In particular, the results of this research study have practical implications in developing interfaces and applications that help organizing personal information items effectively. This study also helps us further understand categorization, information organizing behavior, and personal information management.
Mapping the temporal evolution of scientific community structures
Authors: Velden Theresa , Yu Kan , Yan Shiyan , Lagoze Carl 
Published: April 2015

ABSTRACTWe present results from tracking the temporal evolution of community structures within a research specialty. This extends our previous work in which we generated static community maps that combine co‐author networks and direct citation networks derived from 20‐years of publications in the research specialty. Here, we explore how the temporal evolution of these maps can be used to provide insights into the historical evolution of a field as well as extract more accurate snapshots of the community structures at a given point in time. Such time resolved mappings are an important component in our mixed method approach that integrates network analysis with ethnographic field studies to investigate field‐specific communication and collaboration behaviors in scientific communities (Velden & Lagoze 2013). Evaluating these maps in qualitative interviews with field experts will be the next step in our research.
Privacy and control in online social profiles: Toward a typology of users
Authors: Burkell Jacquelyn , Fortier Alexandre 
Published: April 2015

ABSTRACTThis poster uses Q methodology to investigate subjective perspectives on privacy of and control over social network profiles. Earlier research using interview and focus group techniques suggests that the default conception of online social networks is as public spaces where there is little or no expectation of control over content or distribution. This conception, however, applies largely to information posted by others, and participants frame their own online participation in different ways. The current study explicitly investigates these different subjective perspectives. The results suggest three different user profiles or privacy orientations: one group views their online profiles as spaces for social display, but exert control over content and audience; a second group treats their profiles as spaces for open social display, exercising little control over either content or audience; and a third group views social network profiles as places to post personal information to a controlled audience. These different perspectives lead to different privacy needs and expectations.
Examining data sharing and data reuse in the dataone environment
Authors: Murillo Angela P. 
Published: April 2015

ABSTRACTThe Data Observation Network for Earth (DataONE), a U.S. NSF DataNet Partner, seeks to provide cyberinfrastructure for “open, persistent, robust, and secure access to…earth science observational data”. Scientists participating in DataONE are able to deposit, search, and reuse data available through various DataONE tools. The research presented in this poster‐paper reports on two studies examining data sharing and reuse in the DataONE environment. The two studies include 1) a profiling data assessment that examines the data and metadata being deposited into the DataONE system for data sharing, and 2) a pilot think‐aloud study that examines what factors influence decisions regarding data reuse. From the profiling data assessment, preliminary results indicate that data being deposited into the DataONE for sharing have three specific types of metadata available including a) dataset, b) access, and c) additional metadata. Results also indicated that there is variation regarding the robustness and completeness of information. Additionally, through the think‐aloud study results indicated that particular aspects the metadata information was useful for decision‐making regarding reuse of data for scientists, while other metadata aspects were described as not useful. The results section provide specific details of these findings and demonstrate how these two studies examine both data sharing and reuse within the DataONE environment.
Exploiting latent content based features for the detection of static SMS spams
Authors: Karami Amir , Zhou Lina 
Published: April 2015

ABSTRACTAs the use of mobile phones grows, spams are becoming increasingly common in mobile communication such as SMS, calling for research on SMS spam detection. Existing detection techniques for SMS spams have been mostly adapted from those developed for other contexts such as emails and the web without taking into account some unique characteristics of SMS. Additionally, spamming tactics is constantly evolving, making existing methods for spam detection less effective. In this research, we propose to exploit latent content based features for the detection of static SMS spams. The efficacy of the proposed features is empirically validated using multiple classification methods. The results demonstrate that the proposed features significantly improve the performance of SMS spam detection.
Health information without borders: Foreign‐trained health professionals and labor market integration
Authors: Komlodi Anita , Caidi Nadia , Abrao Aline Lima 
Published: April 2015

ABSTRACTForeign‐trained health professionals (doctors, nurses, physical therapists, and others) arrive in the US and Canada every year to find a professional environment that is often unwelcoming and complex. In this work‐in‐progress poster we explore the experiences and information behavior of these professionals as they search for health‐ and career‐related information to integrate into their new professional environments. Results from this research can in the future support the design of information resources and services to better serve foreign‐trained health professionals.
Influence and provocation: Understanding relationships within a thematic research collection
Authors: Audenaert Neal , McGrew Timothy J. , Kocmoud Christopher 
Published: April 2015

ABSTRACTIn this poster, we present two interfaces for visualizing the relationships between ideas, issues and scholarship within a thematic research collection and discuss a graph‐based data model for representing those ideas. These interfaces are intended to support collection understanding and exploration for non‐specialist users within the context of a collection of 2000 historical documents spanning 300 years. The research question that drives the design of these tools is how to represent the deeply internalized conceptual framework acquired by a scholar over decades of study and communicate that information to non‐specialists effectively.
Cellular plates with auxetic rectangular perforations
Authors: Slann Alex , White William , Scarpa Fabrizio , Boba Katarzyna , Farrow Ian 
Published: April 2015

AbstractThe work describes a cellular structure configuration with a rectangular perforation topology exhibiting auxetic (negative Poisson's ratio) in‐plane behaviour. The rectangular voids used in this structure produce a rigid rotating squares effect. Changes in the sizing parameters of aspect ratio, intercell spacing, and number of unit cells are made through non‐dimensional modelling. The effects on the key properties of in‐plane Poisson's ratio, Young's modulus and shear modulus are investigated. Through numerical modelling and experimental testing the auxetic behaviour is confirmed, with increased negative Poisson's ratio values in comparison to rhomboidal patterns of perforations available in open literature.
Control of extended defects in cast multicrystalline silicon using polycrystalline template

Published: April 2015

AbstractExtended defects were controlled using polycrystalline silicon as a template for cast‐growth of multicrystalline silicon. At the initial stage of growth, small randomly oriented grains with a high density of random type grain boundaries were obtained. With growth, the grain size increased and the fraction of random grain boundaries decreased. Electrical activity of defects was investigated and it was found that with growth, network of small angle grain boundaries became the most electrically active defects. This network of small angle grain boundaries were found to have a tilt angle less than 3° and were mainly found in elongating grains. The density of these highly electrically active grain boundaries increased with growth. This can be attributed to propagation and agglomeration of dislocations into small angle grain boundaries. The high density of random grain boundaries in this ingot may suppress dislocation propagation between grains, however they do not intersect elongating grains enabling dislocation propagation in elongated grains.
