Collaborative information seeking (CIS) behavior of LIS students and undergraduate students: An exploratory case study
Authors: Shahvar Shabnam Shirley , Tang Rong 
Published: April 2015

ABSTRACTThis study investigates the collaborative information seeking (CIS) behavior among three different user groups: LIS students, undergraduates, and a mixture of LIS and undergraduate students. Each group consisted of a pair of participants. Out of 28 participants, 16 were graduate students of library and information science and 12 were undergraduates from different majors. Results of this case study revealed that undergraduate groups visited library website and library databases more frequently than other groups. They had the highest average frequency in reading an abstract or a full text article compared to two other groups. Undergraduate groups also held the highest success rate. Mixed groups had the highest frequency of verbal dialogue and spent the longest time on tasks. Most of the LIS student groups found search results faster and spent the shortest time on completing tasks and reading the abstract and full texts. Surprisingly, LIS groups had the lowest success rate among the three groups. Participants described the positive aspects of collaborative search as gaining greater search insights, good learning process, positive partnership and being more efficient with task completion. They also pointed out that collaboration drawbacks may include not having equal control/sharing of keyboard or mouse and other obstacles in the collaborative decision‐making process. Participants further provided suggestions on database and search engine design to facilitate the collaborative search process.
Interdisciplinarity patterns of highly‐cited papers: A cross‐disciplinary analysis
Authors: Chen Shiji , Gingras Yves , Arsenault Clément , Larivière Vincent 
Published: April 2015

ABSTRACTThis study analyzes the level of interdisciplinarity and interspecialty of highly cited papers. We distinguish research referring to differentdisciplines(referred to as “interdisciplinarity”) and research referring to differentspecialtiesof the same discipline (referred to as “interspecialty”). The results indicate that: (1) interspecialty research, has a greater impact on science development than intradisciplinary (or intraspecialty) research for most specialties and disciplines; (2) interdisciplinary research plays a more important role in Natural Sciences and Engineering than in Social Sciences and Humanities; and (3) interdisciplinary research is becoming more important in science either at the specialty or discipline level.

Published: April 2015

ABSTRACTMakerspaces, designated spaces to foster creativity and technology skills, are increasingly being incorporated into libraries. Although makerspaces in libraries are depicted positively in the literature and are praised by professional organizations, there is little exploration of the acculturation that results as libraries and makerspaces learn to coexist. In keeping with Matt Ratto's model of “critical making,” we used the process of collaboratively building an interactive Readers’ Advisory Device (RAD) that runs on a Raspberry Pi computer to elicit introspection. In this poster we describe how our interdisciplinary group faced challenges working with unfamiliar tools and technology through a non‐hierarchical, collaborative, and iterative process, seeking knowledge and skills from the maker community. We then engaged the wider community around both how and why we developed this device by exhibiting it at a Maker Faire. Our experience taught us about the making process and helped us think critically about the intersection of libraries and makerspace cultural values. We found that making is as much an act of networking as of creation.
How do college students choose mobile health/wellness applications?
Authors: Choi Wonchan , Stvilia Besiki 
Published: April 2015

ABSTRACTThis poster reports on the findings from interviews with fifty college students regarding what mobile health and wellness applications students used and how they choose those applications. In terms of application types, calorie and daily activity counters, such as MyFitnessPal and Lose It!, were most popular for the participants in the study, followed by running trackers, such as Nike+ Running and MapMyRun, and exercise/workout trackers, such as Fitness Buddy and Ab Workouts. Students seemed to prefer free applications and they evaluated and chose applications both indirectly (i.e., based on third party information and recommendations) and directly (i.e., through use).
Functions of Twitter in Digital Libraries
Authors: Xie Iris , Ann Stevenson Jennifer 
Published: April 2015

ABSTRACTTwitter is a popular social media tool for people to connect and communicate with one another. In recent years, digital libraries (DLs) have added Twitter to their lists of social media tools as a way to engage with users. However, how digital librarians and users actually use this social media tool is unknown. In order to gain more knowledge about the use of Twitter, the authors conducted an open coding analysis of Tweets from 15 different DLs for the course of one year. Five types of functions of Twitters in DLs were selected and discussed, which represent the problems, promotion, related resources, social connection and social identity of DLs. In addition, their relationships were also explored.
LAM at Universities: Convergence in Graduate Education

Published: April 2015

ABSTRACTThis poster presents preliminary results from a one‐year project to study the convergence of Library and Information Studies, Archival Studies, and Museum Studies (LAM) education in ALA‐accredited graduate programs in North America. This mixed‐methods study resulted in a survey of graduate programs, and an on‐going series of interviews with key knowledgeable persons within those programs. Initial results reveal a tension between the desire to formalize ties among LAM graduate programs at universities and the desire to adhere to the inherent cultures of Libraries, Archives, and Museums.
The influence of task type on search experience from the perspective of time constraint
Authors: Liu Chang , Zhang Lu , Jiang Qin , Yang Fan , Zhao Yu 
Published: April 2015

ABSTRACTIn this study, we explored the effect of time constraint on information acquisition and knowledge acquisition during search in two types of tasks: information understanding (IU) task and fact finding (FF) task. A user experiment was conducted. Participants were asked to conducted search tasks of these two types with and without time constraint. The results indicated that when no time constraint was set, although users spent significant more time in IU tasks, they produced similar amount of information and acquired similar amount of self‐rated knowledge in IU tasks and FF tasks. When searching under time constraint, even though participants produced significantly more information in IU tasks than in FF tasks, they acquired lower level of knowledge in IU tasks than in FF tasks. These results suggested that it took searchers more time to understand and interpret the information they found in IU tasks and they may first collect much information for later interpretation when given severe time constraint in IU tasks, but not in FF tasks.Categories and Subject DescriptorsH.3.3 Information Storage and Retrieval: Information Search and Retrieval – search process.General TermsMeasurement, Performance, Experimentation, Human Factors.
Parameter tuning: Exposing the gap between data curation and effective data analytics
Authors: Blake Catherine , Gabb Henry A. 
Published: April 2015

ABSTRACTThe “big data” movement promises to deliver better decisions in all aspects of our lives from business to science health, and government by using computational techniques to identify patterns from large historical collections of data. Although a unified view from curation to analysis has been proposed, current research appears to have polarized into two separate groups: those curating large datasets and those developing computational methods to identify patterns in large datasets. The case study presented here demonstrates the enormous impact that parameter tuning can have on the resulting accuracy, precision, and recall of a computational model that is generated from data. It also illustrates the vastness of the parameter space that must be searched in order to produce optimal models and curated in order to avoid redundant experiments. This highlights the need for research that focuses on the gap between collection and analytics if we are to realize the potential of big data.
Primacy of paper: The importance of the medium in records management
Authors: Gruning Jane 
Published: April 2015

ABSTRACTThis poster presents findings from a group ethnographic study of records managers at four different sites. At the site that is the focus of this analysis, research participants’ tasks primarily consisted of examining individual case files to determine if the files should be kept or destroyed under the relevant rules set by records managers. Close observation of work practices showed that application of records management rules varied depending on the medium of the records. This study begins the work of bridging a gap between archival and records management policies for interactions with records across varying media, and empirical research on how people interact with objects on varying media.
Towards building a collection of web archiving research articles
Authors: Ayala Brenda Reyes , Caragea Cornelia 
Published: April 2015

ABSTRACTThe field of Web Archiving exists in a fluid, fragmented, and heterogeneous state. Part of the problem is that this field is relatively new and its literature is scattered across a wide range of journal and conference venues. This makes the state of Web Archiving as a discipline particularly difficult to ascertain. This paper presents an approach to building a collection of articles about the subject. We begin with a small dataset of articles taken from a Web Archiving Bibliography and then proceed to expand it by crawling the Web and collecting additional documents. The crawled documents are then classified using machine learning classification techniques. We show that by extracting the documents’ titles and abstracts and representing them using the “bag of words” approach, we are able to accurately identify documents from the Web crawler as documents that are about Web Archiving. We also discuss our results in the context of Web Archiving as an emerging field.
Accessibility cyberscapes and the digital divide
Authors: Benner Jessica G. , Oh Jung Sun 
Published: April 2015

ABSTRACTIn this paper, we discuss early findings on a study of user generated accessibility information. We utilize data from OpenStreetMap that include tags related to wheelchair accessibility and compare the distribution of these data to other explanatory data collected in the American Community Survey. We perform a linear regression and find that the population of people with disabilities in an area had a stronger relationship with the frequency of data points than household income or the urban status. Future work includes analyzing the accessibility data within the context of other data found in OpenStreetMap, and the use of additional measures associated with the digital divide such as level of education or the number of available access points.
Explicit semantic path mining via wikipedia knowledge tree
Authors: Xia Tian , Chen Miao , Liu Xiaozhong 
Published: April 2015

ABSTRACTWhile classical bag‐of‐word (BoG) approaches represent text content in the word level, recent studies show that knowledge‐based concept indexation is a promising approach to further enhance the text search and mining performance. In this study, we propose a new knowledge indexation/extraction method, Explicit Semantic Path Mining (ESPM), for knowledge‐base text mining. It has roots in a concept‐based vector constructing method, Explicit Semantic Analysis (ESA), which has shown success in text mining tasks. For this new method, given an input piece of text, ESPM can efficiently identify the independent and optimized semantic path(s) on a concept map, which is, in this study, the Wikipedia category tree. Unlike earlier studies focusing on BoG based vector space, ESPM is a semantic path mining algorithm, which generates the top down semantic categories of a given text by leveraging the rich link information between Wikipedia categories and articles. Preliminary experiment based on ODP data shows ESPM delivers high quality independent semantic paths from both precision and ranking viewpoints.
When PIM goes public: A case study of organizedlikejen
Authors: Thomson Leslie 
Published: April 2015

ABSTRACTTypically, information scientists research videos and blogs, two types of online content, with the aim to understand the information behaviors and activities of those who seek and use such sources. Yet, beginning to understand the set of information‐intensive behaviors and activities that accompany online content creation is equally important. This poster presents an early case study of one self‐designated “Original Content Creator,” OrganizedLikeJen, a social media personality found on YouTube—as well as on sites like Tumblr, WordPress, Facebook, Twitter, Instagram, and Pinterest—whose uploads often have an information‐related focus. The objective of this poster is to understand how OrganizedLikeJen might proffer a gateway to the investigation of several topics little taken up in current literature. What are possible information producing and sharing behaviors in these forums? What are possible information‐centric work practices in these forums? How might informal information providing careers be characterized? Could OrganizedLikeJen specifically indicate information popularization among broad audiences?

Axisymmetric thermal consolidation of multilayered porous thermoelastic media due to a heat source
Authors: Ai Z. Y. , Wang L. J. 
Published: April 2015

SummaryThis paper presents an analytical layer element solution to axisymmetric thermal consolidation of multilayered porous thermoelastic media containing a deep buried heat source. By applying the Laplace–Hankel transform to the state variables involved in the basic governing equations of porous thermoelasticity, the analytical layer elements that describe the relationship between the transformed generalized stresses and displacements of a finite layer and a half‐space are derived. The global stiffness matrix equation is obtained by assembling the interrelated layer elements, and the real solutions in the physical domain are achieved by numerical inversion of the Laplace–Hankel transform after obtaining the solutions in the transformed domain. Finally, numerical calculations are performed to demonstrate the accuracy of this method and to investigate the influence of heat source's types, layering, and the porous thermoelastic material parameters on thermal consolidation behavior.

Authors: Hezari Davod , Edalatpour Vahid , Salkuyeh Davod Khojasteh 
Published: April 2015

SummaryIn this paper, we present a preconditioned variant of the generalized successive overrelaxation (GSOR) iterative method for solving a broad class of complex symmetric linear systems. We study conditions under which the spectral radius of the iteration matrix of the preconditioned GSOR method is smaller than that of the GSOR method and determine the optimal values of iteration parameters. Numerical experiments are given to verify the validity of the presented theoretical results and the effectiveness of the preconditioned GSOR method. Copyright © 2015 John Wiley & Sons, Ltd.

AbstractBackgroundStevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) carry a high mortality risk. While identifying clinical and genetic risk factors for these conditions has been hindered by their rarity, large electronic health databases hold promise for identifying large numbers of cases for study, especially with the introduction in 2008 of ICD‐9 codes more specific for these conditions.ObjectiveThe objective of this study is to estimate the validity of ICD‐9 codes for ascertaining SJS/TEN in 12 collaborating research units in the USA, covering almost 60 million lives.MethodsFrom the electronic databases at each site, we ascertained potential cases of SJS/TEN using ICD‐9 codes. At five sites, a subset of medical records was abstracted and standardized criteria applied by board‐certified dermatologists to adjudicate diagnoses. Multivariate logistic regression was used to identify factors independently associated with validated SJS/TEN cases.ResultsA total of 56 591 potential cases of SJS/TEN were identified. A subset of 276 charts was selected for adjudication and 39 (of the 276) were confirmed as SJS/TEN. Patients with the ICD‐9 codes introduced after 2008 were more likely to be confirmed as cases (OR 3.32; 95%CI 0.82, 13.47) than those identified in earlier years. Likelihood of case status increased with length of hospitalization. Applying the probability of case status to the 56 591 potential cases, we estimated 475–875 to be valid SJS/TEN cases.ConclusionNewer ICD‐9 codes, along with length of hospitalization, identified patients with a high likelihood of SJS/TEN. This is important for identification of subjects for future pharmacogenomics studies. Copyright © 2015 John Wiley & Sons, Ltd.
Advancement in treating some features of CIGS thin film solar cells during manufacturing

Published: April 2015

AbstractIn‐line sputtering and selenization have become the industrial standard, but it is difficult to predict and control the local chemical composition of the film. The present communication reports on the material design, device design and process design. These designs use parameters that are closely related to their chemical compositions, as a variation in composition leads to modification of the Poisson equation, current equation and continuity equation. Therefore, there is a need to build a model that relates the optoelectrical properties and device structural parameters that will be loaded into the process simulation, to obtain the complete set of process control parameters. The detailed optical and electrical properties are also investigated for the development of an analytical solar cell simulator. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

ABSTRACTIntroductionThe serotonin 5‐HT1B receptor subtype is involved in the modulation of serotonin release and is a target of interest for neuroreceptor imaging. Previous studies have shown that the serotonin system is affected in Parkinson's disease (PD). Cognitive function, frequently impaired in PD, has been linked to the serotonin system. The aim of this study was to examine whether 5‐HT1B receptor availability in the brain of healthy subjects and PD patients is associated with measures of cognitive function.MethodsTwelve control subjects and ten PD patients with normal mini‐mental state examination scores were included in this study. Cognitive function was evaluated by assessment of semantic, episodic, and working memory, as well as fluency and visual attention. Creative ability, a measure of divergent thinking, was examined with the alternative uses of objects task. PET measurements were performed with the 5‐HT1B receptor‐radioligand [11C]AZ10419369 using the HRRT system.ResultsPD patients showed statistically significant lower measures of semantic and episodic memory, as well as creative ability, compared with control subjects. Statistically significant positive correlations were found in control subjects between creative ability and average 5‐HT1B receptor availability in grey matter, and in PD patients between scores of Beck Depression Inventory‐II and creative ability.ConclusionThough creativity has been conventionally linked to dopamine function, our findings in control subjects suggest a link between 5‐HT1B receptor availability and creative ability. In PD patients, creative ability was significantly associated with depressive symptoms but not with 5‐HT1B receptor availability. This finding deserves further investigation in future studies.
