Effective Acetylene/Ethylene Separation at Ambient Conditions by a Pigment‐Based Covalent‐Triazine Framework
Authors: Lu Yue , He Jia , Chen Yanli , Wang Heng , Zhao Yunfeng , Han Yu , Ding Yi 
Published: October 2017

AbstractA novel covalent‐triazine framework (CTF‐PO71) is designed and prepared from an organic pigment molecule for high‐performance gas separation. The functional sites with different electrostatic potentials on the pore surface of CTF‐PO71 demonstrate a strong interaction between C2H2 and CTF‐PO71 to achieve preferential adsorption of C2H2 over C2H4, thus enabling effective capture of a trace amount of C2H2 from the gas mixture. This is the first organic porous polymer that is capable of separating C2H2 and C2H4. The commercial availability and the low cost of the pigment as well as the high stability of the resultant framework endow CTF‐PO71 with a significant potential for practical applications.

AbstractHelicobacter pylori is a gram‐negative bacterial pathogen that chronically inhabits the human stomach. To survive and maintain advantage, it has evolved unique host–pathogen interactions mediated by Helicobacter‐specific proteins in the bacterial outer membrane. These outer membrane proteins (OMPs) are anchored to the cell surface via a C‐terminal β‐barrel domain, which requires their assembly by the β‐barrel assembly machinery (BAM). Here we have assessed the complexity of the OMP C‐terminal β‐barrel domains employed by H. pylori, and characterized the H. pyloriBAM complex. Around 50 Helicobacter‐specific OMPs were assessed with predictive structural algorithms. The data suggest that H. pylori utilizes a unique β‐barrel architecture that might constitute H. pylori‐specific Type V secretions system. The structural and functional diversity in these proteins is encompassed by their extramembrane domains. Bioinformatic and biochemical characterization suggests that the low β‐barrel‐complexity requires only minimalist assembly machinery. The H. pylori proteins BamA and BamD associate to form a BAM complex, with features of BamA enabling an oligomerization that might represent a mechanism by which a minimalist BAM complex forms a larger, sophisticated machinery capable of servicing the outer membrane proteome of H. pylori.

ABSTRACTBackgroundProspective data on cognition in prodromal Parkinson's disease are limited. The objectives of this study were to assess in prodromal PD (1) if baseline cognition predicts conversion to clinical PD, (2) if baseline dopamine transporter binding predicts longitudinal changes in cognition, and (3) if impaired olfaction predicts future cognitive decline.MethodsProdromal participants were 136 hyposmic individuals enrolled in the Parkinson Associated Risk Study. We examined baseline neuropsychological test performance in PD converters versus nonconverters and the association between baseline dopamine transporter binding and change in cognition. An additional 73 normosmic individuals were included in analyses of the relationship between hyposmia and cognitive decline.ResultsIn prodromal participants, baseline cognitive scores did not significantly predict conversion, but converters performed numerically worse on 5 of the 6 cognitive domains assessed, with the greatest differences in executive function/working memory (0.68 standard deviation lower) and global cognition (0.64 standard deviation lower). Lower baseline dopamine transporter binding predicted greater future decline in processing speed/attention (P = 0.02). Hyposmia predicted greater future decline in language (P = 0.005) and memory (P = 0.01) abilities.ConclusionsGiven hyposmia in the general population predicts cognitive decline, the role of cognition in predicting conversion in prodromal PD needs to be assessed in large cohorts followed long‐term. The dopamine system may be associated with changes in processing speed/attention in individuals at risk for PD. © 2017 International Parkinson and Movement Disorder Society

AimsTo evaluate the significance of mast cell infiltration in interstitial cystitis (IC) by comparison with equally inflamed controls using a digital quantification technique.MethodsBladder biopsy specimens from 31 patients with Hunner type IC and 38 patients with non‐Hunner type IC were analyzed. Bladder biopsy specimens from 37 patients without IC, including 19 non‐specific chronic cystitis (“non‐IC cystitis”) specimens and 18 non‐inflamed bladder (“normal bladder”) specimens, were used as controls. Mast cell tryptase‐, CD3‐, CD20‐, and CD138‐immunoreactive cells were quantified using digital image analysis software to evaluate both mast cell and lymphoplasmacytic cell densities. Mast cell and lymphoplasmacytic cell densities were counted independently in the entire lamina propria and detrusor areas and compared among the four groups.ResultsIn the lamina propria, there were no significant differences in mast cell and lymphoplasmacytic cell densities between Hunner type IC and non‐IC cystitis or between non‐Hunner type IC and normal bladder specimens. In the detrusor, the mast cell densities were not significantly different among the four groups. Mast cell density was correlated with lymphoplasmacytic cell density, but not with clinical parameters.ConclusionsMast cell density is not significantly different between IC specimens and non‐IC control specimens with a similar degree of background inflammation. The intensity of mast cell infiltration generally correlated with that of lymphoplasmacytic cells. We conclude that mast cell count is of no value in the differential diagnosis between IC and other etiologies.
Critical moments in participatory design: Engaging NASA astrobiology researchers via scientometric visualizations
Authors: Gazan Rich 
Published: October 2017

ABSTRACTNASA astrobiology researchers from diverse fields often have little sense of how their work relates to one another. Using document analysis and participatory design methods, this paper reports on a scientometric analysis project to distill essential elements of astrobiology documents to identify them across diverse domains. Twelve NASA astrobiology researchers and administrators were presented with scientometric visualizations in a live setting and (i) demonstrated engagement by actively proposing alternative terms they felt best represented their team's research, (ii) confirmed that the effects of 2007‐2008 cuts in research funding had been accurately reflected in the document corpus and (iii) identified persistent differential impacts on research output across astrobiology's diverse constituent disciplines. The results suggest that this participatory design method provided a critical boundary space where conversations between diverse researchers took place that would have been unlikely to occur otherwise and illustrates the kind of unique contribution information science researchers and professionals can make to interdisciplinary scientific collaborations.

Published: October 2017

ABSTRACTThe layering of games over crowdsourcing tasks has increasingly become a viable approach to motivate participation in crowdsourcing projects. A crowdsourcing game utilizes entertainment to generate useful outputs as byproducts of gameplay. Since crowdsourcing relies on individuals' participation, understanding actual contribution patterns is an important area of research. However, this phenomenon has yet to be adequately investigated. In this paper, we build on our prior research to attempt to answer the question of whether a non‐game‐based mobile app for the crowdsourcing of location‐based content would yield different types of contributions when compared against a game‐based app. Our content analysis of 2,386 contributions in both apps reveals nine categories, divided into (1) those that provide information for navigational purposes or for others to learn about a specific place and (2) those that were meant for personal expressions related to the content creator or those around him/her with the location as a backdrop. The distribution of categories varied between the apps, indicating that the features afforded by the game shaped behavior differently from the non‐game‐based approach to crowdsourcing. Analysis of the contributions also suggests that the game‐based app produced much higher informational content than the non‐game‐based one.
De‐constructing the co‐construction: Researcher stance, the nature of data and community building in an online participatory platform to create a knowledge repository
Authors: Kaplan Samantha J. , Chen Annie T. , Carriere Rachel M. 
Published: October 2017

ABSTRACTIn this article, we provide a reflexive account of the design of the Body Listening Project, a participatory platform in which participants were invited to engage collectively in the building of a public repository. The Body Listening Project was an online collaborative space, with a designated “ThinkSpace,” for participants and moderators to share their experiences of “body listening” and more broadly, self‐management of health. The participatory platform on which the study took place was an active, evolving environment that was shaped by participants of many different backgrounds. In particular, we elaborate upon three critical aspects of our research design: researcher stance, the nature of data, and online community development. It is our hope that explicating the design decisions that were made in this study can stimulate researchers' consideration of these issues in their own projects, as well as inform the design of future research involving collaborative and participatory frameworks.
Identifying structural genre conventions across academic web documents for information use
Authors: Ma Cui–Chang , Cao Shu–Jin 
Published: October 2017

ABSTRACTThe organization and presentation of academic documents on the web are mostly on the documental level. However, what the researchers need is always the particular information pieces of documents rather than the whole. Genre provides us with an expected form and content from both authors and readers; therefore, functional analysis of genre might be employed to decompose web documents into information units for information use. In this vein, this study aims to build the taxonomy of information units within academic web documents for information use based on structural genre theory. The genres chosen include abstract from online bibliography, research article from open access journal, entry of online encyclopedia and academic weblog post. Two sequential studies are conducted. In the first study, the taxonomy with the hierarchy of genre – component – functional unit is firstly built by identification of information units within academic web document genres, and then is validated and refined through corpus in the domain of citation analysis in Chinese. In the second study, user survey is conducted to validate the information units in the taxonomy. The results suggest that the knowledge of social convention of academic web genres in the taxonomy in domain of citation analysis in Chinese is well identified, which can inform the design of search engine to support effective and efficient web information use for academic purposes.
Search successes and failures in query segments and search tasks: A field study
Authors: Wang Yiwei , Liu Jiqun , Mandal Soumik , Shah Chirag 
Published: October 2017

ABSTRACTSearching for information could be difficult or problematic in situations where searchers possess inadequate knowledge and/or vague information needs, often leading to unsuccessful outcomes. Existing studies on search outcomes (successes and failures) have lacked a detailed analysis at query (expression of information need) level from a searcher's perspective and the connection between queries and their corresponding search tasks. In the work reported here, we adopt a mixed‐method approach to both explore how and why searchers succeeded or failed to fulfill their information need with each query and to link these query level outcomes to searchers' overall task goal realization. Twenty‐six participants finished two search tasks in three days in naturalistic settings and reported their experiences in online diaries. The log data containing their actions in nearly 200 query segments, their diary responses and post‐task semi‐structured interviews inspire both in‐depth discussion on search experiences and interesting comparison between successful and unsuccessful searchers. While quantitative analysis depicts the overall relationships between behavioral variables and search outcomes at both query and task levels, qualitative analysis reveals why those relationships took place. In general, searchers who viewed more pages and spent more time in each query segment were more likely to succeed. We also report reasons behind these phenomena.

Published: October 2017

ABSTRACTThis work discusses changes in consumption patterns with the spread of electronic commerce, which started to demand new informational competences in commercial relations. We highlight the concepts of semiotic scenario and information architecture, analyzing the implications of such concepts in the structure of websites dedicated to electronic commerce. In addition, we describe a system for informational organization of the Brazilian e‐stores, analyzing the interactions between the e‐customer with the website's information architecture, along with the subjacent semiotic scenario to the business model.
Navigating the next step: An interactive panel for doctoral students
Authors: Hartnett Liz , Singh Rajesh , Zamir Hassan 
Published: October 2017

ABSTRACTThe proposed session builds on the successes of interactive doctoral student panels sponsored by SIG/ED at earlier ASIS&T Annual Meetings. This year's panel features faculty in various stages of their academic careers. The panelists are prepared to address audience questions on topics of concern to doctoral students, such as the traditional academic job market, alternative career paths including post‐doctoral opportunities, the development of personal research agendas and the challenges of online instruction.The panel discussion will focus on the academic job market and how applicants can present themselves in the best light depending upon the type of position sought. By interacting with the panelists, doctoral students will gain valuable insights on finishing their dissertations, weighing postdoctoral opportunities and preparing for their first academic positions. This session will also provide an anonymous mechanism for doctoral students and new faculty to ask questions without feeling inhibited or intimidated. The panel may be of greatest benefit to those doctoral students nearing the end of their doctoral programs, but will also be useful to new doctoral students and new assistant professors.
Engaging at the margins: Theoretical and philosophical approaches to social justice
Authors: Kitzie Vanessa L. , Radford Marie L. , Radford Gary P. , Budd John M. 
Published: October 2017

ABSTRACTThis interactive panel demonstrates how critical, interdisciplinary theoretical and philosophical approaches outside the field of library and information science (LIS) can foster new ways of thinking about the concept of social justice. The panel consists of four researchers whose scholarship connects to these approaches. The following areas will be discussed: extending the philosophy of justice‐as‐fairness using the work of Amartya Sen, employing Umberto Eco's theoretical approach of semiotics to critique contemporary LIS practices and ideologies and adopting an information practices approach to highlight the importance of sociocultural context, embodiment and unsanctioned resources among those with lesbian, gay, bisexual, transgender and queer (LGBTQ+) identities.The panel will consist of a brief introduction followed by panelist presentations and time for questions and answers from the audience. To build on the potential implications for research and practice, panelists will engage the audience in a paired activity to discuss a set of relevant questions. This activity informs a full audience discussion that concludes the panel. Attendees will leave the panel with an understanding of the current issues related to applying social justice‐centric approaches within LIS that can be implemented into future research and practice.

Published: October 2017

ABSTRACTThe panel aims to update ASIS&T members and information professionals about important standards, specifications and best practice guidelines that have been developed or initiated by the international standards institutions and communities in dealing with open data. The openness and flexibility of the web have created both new opportunities and new challenges for data publishers and data consumers, such as how to represent, describe and make data available (by publishers) in a way that it will be easily found, understood, used and re‐used (by consumers). The panelists will introduce related standards, bring insight to the adoption and implementation of new standards, comment on success and progress in the realm of certain areas such as research data, data on the web (in terms of publishing, annotation and use), metadata in for special domains (such as electronic health records, space debris and genealogical archives) and look at the raising questions and issues. Using the chart from the 2017‐01 W3C recommendations, Data on the Web Best Practices, as context for the panel's presentations, the benchmarks to be used by the panel include the comprehension, processability, discoverability, reuse possibility and effectiveness, trust, linkability, accessibility and interoperability.

The project's main goal is to investigate how to remove barriers to students' enrolment in LIS/IS graduate programs across Europe and at the same time introduce diverse social, cultural and technological experience. The first phase of the longitudinal study conducted in June 2017 explored the motivation and expectations of students enrolling in the EINFOSE European Summer School in Information Sciences (ESSIS). In the final report, the results will attempt to align the expectations of students from different areas with the ESSIS program and thus contribute to the main EINFOSE project goal.
How do medical researchers use open health data? A case study on data reuse behavior of using NHIRD in Taiwan
Authors: Cheng Wei‐Chung , Chiu Ming‐Hsin Phoebe 
Published: October 2017

ABSTRACTData reuse is an emerging academic practice in information sciences studies, and there are diverse studies focusing on this topic. The concept of open health data is becoming a main stream in government administration, academic fields and business/industry. In this study, we analyzed 36 medical journal articles that used data from National Health Insurance Research Database through qualitative method to illustrate open health data reuse behavior in the medical field. The results indicated five stages of data reuse procedure: data re‐appropriating, data recreating, data re‐segmenting, data reconstructing and data revalidating. This paper demonstrates not only medical researchers' data reuse behavior with a practical perspective, but also how they transform quantitative data to valuable clinical discoveries. Moreover, the implications suggest different functionalities for an ideal open health data platform to support researchers' data reuse behavior in each research stage.
Stress, adaptation, growth: International students' approaches to scholarly research and academic integrity
Authors: Click Amanda B. 
Published: October 2017

ABSTRACTInternational students often face unique challenges in adapting to higher education in the United States, and may benefit from specialized academic support. This paper and the accompanying poster outline the findings of a qualitative study exploring international graduate students' adaptation processes as evidenced by their information seeking and use activities. The study was informed by Kim's cross‐cultural adaptation theory. Semi‐structured interviews developed using critical incident technique were conducted with 30 international graduate students enrolled at three North Carolina universities. Participants described a variety of difficulties related to information seeking including finding and understanding resources, and explained how they addressed these challenges. They generally recognized the significance of American academic integrity standards, acknowledging the importance of proper citation and understanding faculty expectations. This paper explores the study findings through the lens of Kim's stress‐adaptation‐growth dynamic. Findings have practical implications for librarians, and other faculty and staff who provide support and training to international students in the United States.

Published: October 2017

ABSTRACTHealth informatics research usually deals with quantitative feedback from information users. Little is known about how information users' qualitative feedback can be used by information providers. The Naître et grandir website (N&G) provides parents with health and well‐being information during pregnancy and until their children are eight years old. In this study, researchers worked with N&G information providers to implement the Information Assessment Method (IAM) for assessing and improving parenting information. Feedback comments were collected from participants who visited the N&G website during the study period and who completed an IAM questionnaire. A coding manual for the analysis of participants' comments was created and developed by the researchers in partnership with information providers. This coding manual was used to create an online knowledge management system to facilitate all future coding of comments. This system allows website editors to receive feedback from their readers daily, allowing them to act on it more rapidly and, therefore, shortening the feedback to action time. This online system can be adapted by other websites' editors to collect information users' comments and improve their online resources.
