Lack of observed movement response to lead exposure of California condors
Authors: Poessel Sharon A. , Brandt Joseph , Uyeda Linda , Astell Molly , Katzner Todd E.
Published: October 2017

Lead poisoning is an important conservation concern for wildlife, and scavenging birds are especially at risk from consumption of carcasses of animals killed with lead ammunition. Because current methods to identify lead exposure require animal capture and blood collection, management would benefit from the development of a less costly and noninvasive behavioral test for illness in wild animals. We attempted to design such a test to identify lead exposure in California condors (Gymnogyps californianus) that we tracked with global positioning system (GPS) telemetry in southern California, USA, 2013–2016. We measured blood‐lead concentrations in tracked birds and expected that flight behavior would be influenced by lead exposure; thus, we measured the effect of blood‐lead concentrations on 2 different types of movement rates and on the proportion of time condors spent in flight. We found no effect of lead exposure on any of these 3 behavioral metrics. Our work suggests that the measurements we took of flight behaviors were not a useful tool in predicting lead exposure in the mildly to moderately exposed birds we studied. Wild birds are effective at hiding illness, especially condors who have a strong social hierarchy in which showing weakness is a disadvantage. However, focusing on behaviors other than flight, expanding the sample studied to include birds with a wider range of lead concentration values, or analyzing tissues such as feathers (rather than, or in addition to, blood) may be more useful for identification of lead exposure and other diseases that may limit wildlife populations. © 2017 This article is a U.S. Government work and is in the public domain in the USA.
Moose response to high‐elevation forestry: Implications for apparent competition with endangered caribou
Authors: Anderson Meghan , McLellan Bruce N. , Serrouya Robert
Published: October 2017

Habitat disturbance threatens woodland caribou (Rangifer tarandus caribou) by altering inter‐tropic relationships, which causes predation rates to increase. Of particular concern is the increase in early seral vegetation in high‐elevation caribou summer habitat created by the recent expansion of logging into these forests. Deep snow confines the relatively abundant moose (Alces alces) population to valleys during winter, but in summer they can move up slope, where their spatial overlap with caribou increases. Wolves (Canis lupus) follow moose, their primary prey, up slope and occasionally encounter and kill caribou. We tested the hypothesis that early seral vegetation in high‐elevation cutblocks (i.e., logged areas) attracts moose into mountain caribou summer habitat, and thereby increases the spatial overlap between caribou, moose, and wolves. To test our hypothesis, we examined how moose selection for early seral vegetation changed with elevation, how moose used undisturbed habitat, and how the proportion of early seral vegetation at high elevations in a moose home range was related to the amount of time moose spent at high elevations. Moose selection for cutblocks increased with elevation; however, when moose were at high elevations they spent the majority of their time in old‐growth forest where they were likely browsing on understory shrubs, and the area of high‐elevation cutblocks in moose home ranges did not affect the amount of time moose spent at high elevations. When we further explored the relationship between the amount of early seral vegetation at high elevations and the amount of time moose spent at high elevations, we found moose spent more time at high elevations when total early seral vegetation (from natural sources and cutblocks) increased, but there was little evidence that either type, on their own, influenced moose to use higher elevations. We conclude that although moose select cutblocks, the influence of high‐elevation cutblocks on moose was minor in our study. Our results and those of other studies suggests low‐elevation logging in moose winter ranges has led to an increased number of moose, and likely has a greater effect on moose distribution than logging at higher elevations. These insights can help guide management of apparent competition between moose and caribou. © 2017 The Wildlife Society.
Gradient Chiral Metamirrors for Spin‐Selective Anomalous Reflection

Published: October 2017

Metasurfaces, the phase‐engineered quasi‐2D interfaces, have attracted intensive interest due to their great capabilities in manipulating the reflection, refraction and transmission of electromagnetic waves. Here, we demonstrate the design and realization of a gradient chiral metamirror tailored for spin‐selective anomalous reflection based on the theory of Pancharatnam‐Berry phase. Asymmetric split ring resonators are employed as the basic meta‐atoms for strong circular dichroism. Dispersionless phase discontinuities are achieved by adjusting the orientation of the meta‐atoms, and spin‐dependent absorption is realized by introducing a chiral resonance. Theoretical results predict both broadband beam deflection and spin‐selective absorption for circularly polarized waves in a designer metamirror. Experimental verification of this bifunctional performance is implemented at microwave frequencies and the measured results agree well with the simulation ones. Such chiral metamirrors could pave an avenue towards spin‐selective modulation of the wavefront and might find promising applications in planar electromagnetic devices.
Simple Preparation of Thiol–Ene Particles in Glycerol and Surface Functionalization by Thiol–Ene Chemistry (TEC) and Surface Chain Transfer Free Radical Polymerization (SCT‐FRP)
Authors: Hoffmann Christian , Chiaula Valeria , Yu Liyun , Pinelo Manuel , Woodley John M. , Daugaard Anders E.
Published: October 2017

Thiol–ene (TE)‐based polymer particles are traditionally prepared via emulsion polymerization in water (using surfactants, stabilizers, and cosolvents). Here, a green and simple alternative is presented with excellent control over particle size, while avoiding the addition of stabilizers. Glycerol is applied as a dispersing medium for the preparation of off‐stoichiometric TE microparticles, where sizes in the range of 40–400 µm are obtained solely by changing the mixing speed of the emulsions prior to crosslinking. Control over surface chemistry is achieved by surface functionalization of excess thiol groups via photochemical thiol–ene chemistry resulting in a functional monolayer. In addition, surface chain transfer free radical polymerization is used for the first time to introduce a thicker polymer layer on the particle surface. The application potential of the system is demonstrated by using functional particles as adsorbent for metal ions and as a support for immobilized enzymes.
Ferric Citrate Supplementation Reduces Red‐Blood‐Cell Aggregation and Improves CD163+ Macrophage‐Mediated Hemoglobin Metabolism in a Rat Model of High‐Fat‐Diet‐Induced Obesity
Authors: Chang Ting‐Yun , Liu Kai‐Li , Chang Cheng Sheng , Su Chien‐Tien , Chen Seu‐Hwa , Lee Yu‐Chieh , Chang Jung‐Su
Published: October 2017

Scope

In adults, >90% of the daily iron requirement is derived from macrophage‐mediated heme iron, recycling from senescent red blood cells (RBCs) or free hemoglobin (Hb). Currently, the effects of pharmacological doses of iron supplementation on RBCs and heme iron recycling in obesity are unclear.

Methods and results

Sprague Dawley rats are fed a standard diet or a 50% high‐fat diet (HFD) with (0.25, 1, and 2 g of ferric iron per kg diet) or without ferric citrate supplementation for 12 weeks. Ferric iron increases hepatic iron accumulation in macrophages and hepatocyte‐like cells. Compared with rats that received the standard diet, HFD‐fed rats exhibit higher RBC aggregation and serum‐free Hb levels but lower LVV‐hemorphin‐7 levels. These effects are reversed by ferric citrate supplementation. Immunofluorescent staining reveals that ferric iron increases the expression of hepatic CD163+ macrophages and heme oxygenase (HO)‐1. A further analysis reveals the dose‐related effects of ferric iron on hepatic globin degradation proteins (cathepsin D and glyoxalase 1), cytochrome p450 reductase expression, and HO‐1 enzyme activity.

Conclusions

Ferric citrate supplementation reduces RBC aggregation and improves CD163+ macrophage‐mediated Hb metabolism in HFD‐induced obese rats. These findings suggest that ferric citrate may be explored as an alternative treatment method for RBC dysfunction.

Probing the compatibility and interaction of energetic binders based on 3,3‐bis(azidomethyl)oxetane with some explosives: thermal, interfacial and simulation studies
Authors: Li Bingjun , Niu Hu , Zhang Jun , Li Guoping , Luo Yunjun , Zheng Jian
Published: October 2017

Several polymer binders based on 3,3‐bis(azidomethyl)oxetane (BAMO) were studied to explore the compatibility and interaction of the energetic binders with three common energetic oxidants. The compatibilities were studied by differential scanning calorimetry and ratings were obtained according to evaluated standards. The results showed that all the binders based on BAMO had good compatibility with cyclotrimethylenetrinitramine, cyclotetramethylenetetranitroamine and hexanitrohexazaiso‐wurtzitane. The work of adhesion (Wa) between binders and explosives was tested via measurement of contact angle and the results are in the following order: chain‐extended poly(3,3‐bis(azidomethyl)oxetane) (PBAMO) by isophorone diisocyanate (IPDI‐CE) with diethyl bis(hydroxymethyl) malonate (IPDI‐DBM‐CE) > chain‐extended PBAMO by IPDI‐CE > PBAMO. In addition, similar results were found in the binding energies reported by molecular dynamics, and the average values of Ebinding for the IPDI‐DBM‐CE system were larger than Ebinding for the other systems due to the formation of hydrogen bonds between –COOEt and –NO2, which improve the bonding abilities. © 2017 Society of Chemical Industry
Tweets may be archived: Civic engagement, digital preservation and obama white house social media data
Authors: Acker Amelia , Kriesberg Adam
Published: October 2017

As part of his presidential transition, the administration of Barack Obama included social media data among the materials transferred to the National Archives and Records Administration (NARA). In addition, this social media collection comprising data from Twitter, Facebook and Vine was distributed to organizations and researchers to explore and investigate. In this paper, we present our initial observations on the first social media presidency through the lens of its data, extracted from their native platforms. While the data speak to the engagement cultivated by the administration in its use of social media, the collection contains as many questions as it does answers. The completeness, metadata and accessibility of these materials remain unclear, potentially limiting the use of the collections in research and beyond. The paper analyzes platform‐specific issues and offers potential solutions to address the preservation and access challenges to social media data. We conclude with implications for the digital preservation community and social media researchers to consider when approaching social media data collections.
Awareness and usage of altmetrics: A user survey
Authors: Aung Htet Htet , Erdt Mojisola , Theng Yin‐Leng
Published: October 2017

As the way of evaluating research outputs has gradually changed, and the dissemination of scholarly materials online has gotten easier, research studies investigating the awareness and usage of social media in academia have also been on the rise. The number of user surveys on the awareness and usage of altmetrics (emerging alternative metrics based on social media) has, however, remained low. This paper presents the findings of an online survey, which are the results of the first phase data collection of a user survey on the awareness and usage of altmetrics in academia. Our findings show that article views and downloads from online digital libraries or repositories are very well‐known. The most used altmetrics are mentions and shares on social networks. Mentions in blog posts and topics in a forum are also popular altmetrics. Interestingly, this study reveals a tendency for non‐faculty staff to be more aware of altmetrics. Furthermore, we also investigate how the usage of social media correlates with the usage of altmetrics. The findings show medium to large correlations between the usage of social media and the usage of altmetrics, which means academics who use social media often, also tend to use altmetrics often.
Before information literacy [Or, Who Am I, as a subject‐of‐(information)‐need?]
Authors: Day Ronald E.
Published: October 2017

In this paper, I discuss an alternative to information literacy and technical fixes for fake news and other such misleading information: the education and self‐interrogation of the subject who needs information. Information has many different forms, types of truth claims and criteria for truth. Much of our daily information intake has nothing to do with true or untrue knowledge, but rather, involves tastes and opinions. If we confuse the conditions for public or learned knowledge with these, or even if we do not recognize how such knowledge also has its own institutional senses of taste, we will mislead ourselves based on false assumptions about what it is that different documents can inform us of. The subject‐of‐(information)‐need, or the “user,” is the bedrock notion of the subject in information retrieval, but it is constructed by the information environment it finds itself within. If the user cannot judge this environment before using it, then information literacy cannot be of enough help.
Trust in qualitative data repositories
Authors: Frank Rebecca D. , Chen Zui , Crawford Erica , Suzuka Kara , Yakel Elizabeth
Published: October 2017

This paper applies Pirson and Malhotra's (2011) framework for organizational trust to data reuse in an educational context. Their framework delineates stakeholders along two axes: depth of the interactions (e.g., shallow or deep) and the locus of the relationship (e.g., internal or external). We analyzed 139 survey responses and 44 in‐depth interviews with users of repositories holding video records of practice. We found that factors such as data quality, co‐production of data between the repository and data producer, responsiveness of staff, and transparency of curation processes influenced trust, and that responsiveness and transparency were of particular importance for trust development for users with deeper interactions and a more internal loci of relationships to repositories.
Understanding and modeling behavior patterns in cross‐device web search
Authors: Han Shuguang , He Daqing , Chi Yu
Published: October 2017

Recent studies have witnessed an increasing popularity of cross‐device web search, in which a user resumes a previously started search task from one device to a later session on another. The complexity of this novel search mode, mainly due to the involvement of interruptions and multiple devices, makes users conduct new types of search behaviors and adopt novel search patterns. Though past research has studied this new search mode, there still lacks a sufficient understanding of cross‐device search behaviors. To better understand users' behavioral patterns, we adopted hidden Markov model (HMM) to model observed cross‐device search behaviors and their underlying search pat‐ terns under the same framework. HMM is a widely adopted machine learning technique with the main assumption that observations (e.g., observed search behaviors) are driven by hidden variables (e.g., hidden behavioral patterns). Utilizing the data collected from a user study consisting of two types of cross‐session search conditions – mobile‐to‐desktop (M‐D) and desktop‐to‐desktop (D‐D) – we demonstrate the validity of using HMM for modeling and identifying hidden behavioral patterns, and based on the identified patterns, we discover that re‐finding is a common pattern at the beginning of the continued search session, and querying, exploitation and exploration contribute to the dominated behaviors in later search stages. Our results also show clear device effects on cross‐device search (M‐D) vs cross‐session search (D‐D). All these evidences confirm that better support mechanisms are in critical need for a cross‐device search and the HMM‐ based modeling can help.
On shapes and sizes: Measuring diversity of technological engagement through digital visitors and residents maps
Authors: Harvey William , Hood Erin M. , Connaway Lynn Silipigni
Published: October 2017

The Digital Visitors and Residents (V&R) project developed a mapping exercise to help individuals better understand their engagement with technology and the web. The map creation process and the opportunity for individuals to share their stories in a group setting can be fun, informative and educational. In this paper, we show that collections of V&R maps can be sources of rich and interesting information about similarities and differences in individuals' engagement with technology. Computational methods such as shape analysis and machine learning can be used to distill this information from collections of V&R maps. We present several models, techniques and algorithms for V&R map analysis that may be familiar to many data scientists and software developers, including a shape metric that captures properties of shapes with intuitive meaning and interpretation in the V&R context. Patterns and trends emerging from collections of maps can help a team better understand their similarities and differences in engagement with technology or help inform decisions on the design of information technology or library technology services. We provide examples of these techniques using data collected in various V&R mapping sessions. Finally, we introduce a V&R mapping web application designed for touchscreens that can ease data collection for computational analysis and provide a fun and engaging experience for mapping exercise participants.
ERA 2.0: The national archives new framework for electronic records preservation
Authors: Johnston Leslie
Published: October 2017

The United States National Archives and Records Administration (NARA) is refactoring its Electronic Records Archive (ERA) systems used for scheduling, transferring, processing, reviewing, describing, transforming, and storing electronic records received from U.S. government agencies for permanent preservation in support of long‐term public access to federal records. The project is following an Agile approach, toward the end of implementing a modular, cloud‐based suite of tools and microservices to support archival functions across the electronic records lifecycle. The implementation will also upgrade digital preservation functionality extant in the current production system, and enable additional efficiencies and automation in the processing of electronic records at scale to make records available to the public more quickly.
Evaluation of features to predict the usefulness of online reviews
Authors: Kim Heejun , Arguello Jaime
Published: October 2017

Checking online reviews before purchasing goods or using services has become increasingly common. However, it is difficult to select useful reviews, and concerns about fake reviews are growing. Many online review systems use recency and user‐generated usefulness votes in order to prioritize reviews for users, but there is much room for improvement. In this work, we focus on evaluating the effectiveness of a large number of features for predicting the usefulness of online reviews, including features that have not been commonly evaluated in prior work (e.g., social network measures). Features were grouped into hierarchical categories that might represent factors impacting perceived usefulness of Yelp users. Using all features, a binary classifier achieved a high level of accuracy (0.889). Additionally, a feature ablation study found that several feature groups yielded statistically significant improvements. Interestingly, many of the features that improved performance are not the types of measures that are displayed to users in commercial online review services such as Yelp and are the measures that are rarely used to prioritize reviews for users. Our study results suggest different types of information that online review services might want to use in ranking and displaying reviews for users.
Affordances and constraints in the online identity work of LGBTQ+ individuals
Authors: Kitzie Vanessa L.
Published: October 2017

This research examines how social networking sites (SNS) and search engines (SE) afford and constrain practices related to the development of lesbian, gay, bisexual, transgender, and queer (LGBTQ+) identities. Semi‐structured interviews were performed with 30 LGBTQ+ individuals from the United States between the ages of 18 and 38. Data analysis identified these key affordances: a) identity expression, b) connecting to similar others, c) information access, and d) information control. Key constraints are: a) identity expression, b) information control, c) curation, and d) information access. Whether SNS and SE provide affordances or constraints is influenced by how participants ascribe meaning to these technologies within their everyday lives. Therefore, SNS and SE do not yield deterministically good or bad outcomes. Instead outcomes are shaped by sociocultural context and material properties of the technologies. Findings reveal implications of everyday technology use for LGBTQ+ individuals and suggest how they can leverage affordances and mitigate constraints of SNS and SE to manage identity work.
Toward an understanding of cross‐media appeals for readers' advisory
Authors: Lee Jin Ha , Windleharth Travis , Cho Hyerim
Published: October 2017

Readers' advisory services in libraries have traditionally focused heavily on the recommendation of books and audiobooks, excluding wide swaths of other media in the library's collection. To provide readers' advisory across a variety of media formats, we identify and investigate common appeal factors across multiple types of media, including books, films, video games, graphic novels, and music. The project was conducted in two phases: a domain analysis and a user study. During the first phase, we reviewed existing literature and consulted with domain experts to identify 19 appeals across different media types. In the second phase, we interviewed 30 participants who actively consume two or more types of media to understand what kinds of appeals are important and relevant to them when selecting media to consume. We discuss the five most prominent appeals—mood, setting, complexity, character, and theme—in detail, followed by implications on using these cross‐media appeals in readers' advisory.
Exploring prestigious citations sourced from top universities across disciplines
Authors: Luo Feiheng , Sun Aixin , Erdt Moijsola , Raamkumar Aravind Sesagiri , Theng Yin‐Leng
Published: October 2017

There have been many studies on the factors influencing paper citation counts. A number of studies have focused on the citing papers, and corresponding methods were proposed to measure the prestige of citations based on the journal impact factors, the total citation counts and the PageRank algorithm values. However, there are drawbacks to these methods. In this paper, we propose a novel method to identify prestigious citations from the affiliation of the citing paper. Specifically, if the authors of the citing paper are affiliated with a prestigious university, the citing paper could be counted as a prestigious citation. As a pilot, we used the top 200 universities on the QS World University Rankings 2015 to identify the prestigious universities so that the prestigious citations, named as QS citations, were identified accordingly. Experimental results validated that QS citations have more important impact on the cited papers than other citations. Papers with QS citations have better performance across most disciplines not only in total citation counts, but also in altmetrics such as the Altmetric Attension Score and Mendeley reader counts.
Investigating barriers to “using information” in electronic resources: A study with e‐book users
Authors: Potnis Devendra , Deosthali Kanchan , Pino Janine
Published: October 2017

Students' ability to use information plays a key role in influencing their adoption and continued usage of e‐books. This pilot study investigates the barriers to using (i.e., searching, managing, processing and applying) information in e‐books experienced by 25 library and information science graduate students (LISGS) at a land‐grant university in the United States. The analysis of study participants' in‐depth qualitative responses using grounded theory principles reveals 60 barriers that affect their ability to use information. These barriers are related to (a) e‐readers, (b) features of e‐books, (c) psychological, somatic, and cognitive status of the respondents, (d) cost and (e) policies. We present the adverse effects of these barriers on the respondents' ability to search, manage, process and apply information in e‐books. For instance, the psychological, somatic and cognitive statuses of respondents affect their ability to process information the most. Barriers related to e‐readers and e‐books have collectively the most damaging effect on the respondent's ability to search, manage, process and apply information. Due to a series of unavoidable barriers, respondents who originally intend to use e‐books for utilitarian purposes end up using this electronic resource mostly for hedonistic reasons. Implications are discussed at the end.
An exploration of reasons for query reformulations
Authors: Rha Eun Youp , Shi Wei , Belkin Nicholas J.
Published: October 2017

Query reformulation is the major method by which information seekers can communicate their information searching intentions to information retrieval systems. Despite a good deal of significant research on types of query reformulations, we still know little about why people reformulate their queries in various ways. We report on a study which elicited people's reasons for query reformulation and investigated the relationships between those reasons and types of query reformulations, and to the searchers' previous information search intentions. Based on these data, we propose a faceted classification of reasons for query reformulation; we find that the frequency of reasons for query reformulation is highly skewed to one type; we find that multiple reformulation types are used for multiple reasons; and, we both confirm and expand upon Xie's (2002) inventory of interactive search intentions. Implications of these results for further work and information retrieval system design are discussed.
Computational content analysis of negative tweets for obesity, diet, diabetes, and exercise
Authors: Shaw George , Karami Amir
Published: October 2017

Social media based digital epidemiology has the potential to support faster response and deeper understanding of public health related threats. This study proposes a new framework to analyze unstructured health related textual data via Twitter users' post (tweets) to characterize the negative health sentiments and nonhealth related concerns in relations to the corpus of negative sentiments regarding diet, diabetes, exercise and obesity (DDEO). Through the collection of six million Tweets for one month, this study identified the prominent topics of users as it relates to the negative sentiments. Our proposed framework uses two text mining methods, sentiment analysis and topic modeling, to discover negative topics. The negative sentiments of Twitter users support the literature narratives and the many morbidity issues that are associated with DDEO and the linkage between obesity and diabetes. The framework offers a potential method to understand the publics' opinions and sentiments regarding DDEO. More importantly, this research provides new opportunities for computational social scientists, medical experts and public health professionals to collectively address DDEOrelated issues.

This paper reports quantitative and qualitative findings from a systematic literature review of user studies of patient portals. A deductive content analysis was performed using six human values identified in a prior study: privacy, confidentiality, security, trust, transparency and agency. Each of the 52 articles in the corpus included invocations of at least one of these human values, supporting their salience for understanding the user experience of patient portals. The paper concludes with a discussion of the implications of this analysis for value‐sensitive design of patient portals, including indicating potential future research directions.
Does it matter which search engine is used? A user study using post‐task relevance judgments
Authors: Sünkler Sebastian , Lewandowski Dirk
Published: October 2017

The objective of this research was to find out how the two search engines, Google and Bing, perform when users work freely on pre‐defined tasks, and judge the relevance of the results immediately after finishing their search session. In a user study, 64 participants conducted two search tasks each, and then judged the results on the following: (1) the quality of the results they selected in their search sessions, (2) the quality of the results they were presented with in their search sessions (but which they did not click on), (3) the quality of the results from the competing search engine for their queries (which they did not see in their search session). We found that users heavily relied on Google, that Google produced more relevant results than Bing, that users were well able to select relevant results from the results lists and that users judged the relevance of results lower when they regarded a task as difficult and did not find the correct information.
Evaluating metadata schema for murals and stone cave temples: Towards digitizing cultural heritage
Authors: Hu Xiao , Ng Jeremy , Xia Shengping , Fu Yonnie King Yiu
Published: October 2017

Despite efforts and attempts on preserving cultural heritages around the world, few studies have been conducted on metadata schema of murals and stone cave temples which are often high value heritages dating from ancient times. The literature is also scarce in user‐centered evaluation of metadata schema of this kind. This study therefore aims to offer insights on developing and evaluating a drafted metadata schema for digitizing and preserving historic murals and stone cave temples. In‐depth interviews were conducted with 15 scholars and professionals whose work was related to murals and stone cave temples. A coding framework was designed to analyze the interview transcripts. Initial findings show that users' seeking behaviors for cultural heritage information corroborated with their perceived importance of specific metadata elements. The coding schema developed in this study can serve as a framework for follow‐up evaluations of metadata schemas of this kind, contributing to the ongoing development of cultural heritage metadata.

Seeking balance: Professional development needs of tenured information science faculty
Authors: Lopatovska Irene , O'Brien Heather , Rorissa Abebe , Ivanović Martina Dragija , Julien Heidi
Published: October 2017

There is minimal, mainly anecdotal, evidence of discourse about the professional development of information science (IS) academics. In an effort to initiate discussion on professional development and encourage information sharing among IS faculty and administrators, we organized a panel at the 2016 Annual Meeting of ASIS&T (Lopatovska et al., ). The panel brought attention to the professional development resources and strategies available to mid‐career faculty and uncovered the need to continue the discussion. This proposed interactive panel aims to identify tenured IS faculty members' needs related to their scholarly, teaching and service pursuits, explore professional wellbeing and work climate, share best practices and brainstorm potential solutions for some of the identified issues. The issues and solutions uncovered during the panel discussion will be shared with the broader community with the hope that recommendations can be adopted and acted upon by individuals, academic institutions and professional associations. The panel will be of interest to faculty, doctoral students and academic administrators.
Learnsourcing: Is it working or failing, and where to go from here?
Authors: Rath Manasa , Zakharchuk Oleksandr , Shah Chirag , Oh Sanghee , Gazan Rich , Subramaniam Mega
Published: October 2017

Online learning has taken great leaps forward with the emergence of Web 2.0 and has paved the path for learning technologies that can be conveniently accessed by users provided they are connected to the Internet. One of the most profitable learning techniques, “Learning from the crowd,” or augmenting “collective intelligence,” has attracted the attention of several learners who seek information in terms of knowledge access. This provides an admirable environment for learning with peers rather than learning alone. However, having access to these online learning technologies does not simply give the users the chance to optimize learning. In addition, researchers have expressed ethical concerns related to issues like accessibility, quality, authenticity, and reliability of content. Taking into consideration the pluses and minuses of “crowdsourced learning,” each of the panelists in this program will shed light on how to use the “wisdom of crowds” or “collective intelligence” to better articulate the process of learning in context of such ethical issues. Each of the panelists comes from a different field of expertise (Information Science, Library Science, e‐Learning, Learning Analytics, and Education). This diversity of experience will be reflected in the different perspectives presented in the area of crowdsourcing in education. The session will conclude with the panelists' presentation of significant comments that would emerge in the discussion.
Organizational and institutional work in data infrastructures
Authors: Shankar Kalpana , Eschenfelder Kristin
Published: October 2017

The long‐term sustainability of data archives and other research information infrastructures is a growing concern as stakeholders seek to ensure that resources invested in infrastructure development endure beyond the original project funding period. For this reason, data infrastructure research has gone beyond the technical work of data management, standardization and digital preservation. There is also a growing body of research that looks at the organizational practices and structures of data repositories and infrastructures for the long term and how they shape and reflect technologies, policies, stakeholder needs and priorities, professions and business models.

We intend to use this panel to engage the audience in an ongoing conversation about organizational studies, sustainability planning and infrastructure. Panel members will present their research on these topics in different case sites and explore how governance, policies and organizational structures and practices are involved in the maintenance and repair of data infrastructures. We want to know more from the audience about how they are examining policies, business models, governance structures and artifacts in other sites; gaps and needs in research and practice; and next steps for researchers. Some questions of interest: How do repositories define success? How do they make their case for long‐term funding and institutional homes? What scalar issues will arise in the context of even bigger data sources? How do data projects end? We will engage each other and the audience in discussing these questions and concerns.
In between data sharing and reuse: Shareability, availability and reusability in diverse contexts
Authors: Yoon Ayoung , Jeng Wei , Curty Renata , Murillo Angela
Published: October 2017

Although data availability cannot be considered the sole predictor of effective reuse, because only accessible and well‐managed data can make reuse possible, data reuse is contingent on the availability of data. It is critical to understand the nature of shareability, availability and reusability, and their synergy and relationships, to further understand the dynamics of data reuse practices in multiple environments and contexts.

This panel aims to closely examine aspects related to data shareability, availability and reusability, based on the assumption that each condition poses a cumulative effect on each other and impacts the efficiency and efficacy of the research data reuse process. The panelists will present their findings and perspectives regarding data availability, between academic and non‐academic; data shareability and data reusability, social sciences and earth science, researchers' and journal publishers' perspectives. Presentations will be followed by an interactive session taking the team‐based approach, with the expectation to engage participants in discussion and experience‐sharing, and to contribute in terms of practice and research with the current knowledge and applications.
Data play: Participatory visualisation to make sense of data
Authors: Anderson Theresa Dirndorfer , Knight Simon , Tall Kelly
Published: October 2017

This visual presentation invites conference participants to use data play to tap into the creative capacity of visual ideation for individual and collaborative learning about (their) data. The authors discuss the application of a hand‐drawn self‐visualisation approach to data understanding to draw attention to the space of representational possibilities, the power of representation interactions and the performativity of information representation. The visual presentation takes an interactive and emergent approach to exploring tactile, visual modes of self‐expression, sense‐making and communication, inviting conference participants to dabble and doodle and think visually about the conference. Over time, the visual artefact will be transformed by and through this community input. Through this collective visual practice, we heed Lupi's call to bring data to life as we make sense of our data traces.
Visual research methods with children and youth: Opportunities & challenges
Authors: Barriage Sarah , Li Xiaofeng , Lopatovska Irene , Mabbott Cass
Published: October 2017

Visual research methods involve the incorporation of visual material such as photographs, artwork and video into the research process. This approach to research is particularly well suited for use with children and youth as it complements verbal and written data collection methods, which some children and youth may find challenging. This video presentation includes a brief overview of three specific types of visual research methods used in recent library and information science research studies with children and youth. An overview of each visual research method is provided, as well as a discussion of the advantages and challenges associated with each method. The video includes examples of the types of research questions for which the surveyed visual research methods might be best suited, as well as associated ethical issues.
An open health data engagement ecosystem model: Are facilitators the key to open data success?
Authors: Begany Grace M. , Martin Erika G.
Published: October 2017

Over the last decade, a rapidly growing open data movement has resulted in government agencies quickly publishing a large volume of data, and the data's subsequent use among a variety of open data consumers. Understanding the activities, actors, technologies and factors enabling open data publication and use has been the subject of discussion among academic researchers and practitioners. However, research is limited, with few empirical studies on open data collecting primary research data from the health domain. To address this gap, we conducted 53 semi‐structured key informant interviews with participants in the open health data ecosystem in a variety of roles. Interview data were analyzed using a grounded theory approach to identify common themes and develop insights into the objectives, activities and desired outcomes of the open health data ecosystem. We found that data facilitators – data advocates, typically external to government agencies – are critical to this process by facilitating open data awareness and successful use. We applied activity theory to examine the facilitator theme and develop a preliminary model of the open health data ecosystem, including the roles, responsibilities and activities of different participants and the role of these facilitators. Our findings suggest that consumers' successful engagement with open health data is fostered by, and perhaps dependent upon, facilitators' activities. These empirically based insights into the structure and workings of the open health data engagement ecosystem can inform jurisdictions' development of open health data engagement strategies thereby improving the success of their open health data initiatives.

Recognizing that current curricula address but a sliver of the wide range of careers pursued by information studies graduates, a team worked collaboratively to design a syllabus for a graduate course dedicated to exploring the societal frames and characteristics of information work. Ultimately comprising 10 modules, the syllabus centers students' awareness of an expanded occupational landscape and evaluation of policies and labor structures impacting information workers. Created over the course of a semester, the syllabus complements an earlier set of empirical studies that revealed areas in which information educators might focus future teaching efforts. This paper articulates the role for iterative and collaborative processes in curriculum development and doctoral study around information work – a research arena requiring macroscopic and future‐oriented thinking. We present the topical and pedagogical organization of the new syllabus and suggest paths forward for integrating its key concepts at other graduate and undergraduate levels of information studies coursework.
Information world mapping to explicate the information‐care relationship in dementia care
Authors: Dalmer Nicole
Published: October 2017

Information world mapping is a helpful data elicitation technique to make visible the hidden work of finding, using and making sense of information. This methods‐based paper explores the utility of a mapping exercise both within an institutional ethnographic study and in eliciting informants' understandings and descriptions of their care‐related information work. Eleven family caregivers of community‐dwelling older adults living with dementia drew maps of their information worlds. Each map depicts a unique combination of information resources (people, agencies, texts and websites) accessed, relationships that shape the information work in addition to key locations frequented to access information. Given the difficulty in delineating the boundaries of information, the mapping exercise served as a helpful tool for caregivers to make visible the intricacies of their information work, including the barriers encountered and inventive strategies created to access, use and translate information needed to guide and support their care work.
