Normal edge‐colorings of cubic graphs
Authors: Mazzuoccolo Giuseppe , Mkrtchyan Vahan
Published: October 2019

A normal ‐edge‐coloring of a cubic graph is a proper edge‐coloring with colors having the additional property that when looking at the set of colors assigned to any edge and the four edges adjacent to it, we have either exactly five distinct colors or exactly three distinct colors. We denote by the smallest , for which admits a normal ‐edge‐coloring. Normal ‐edge‐colorings were introduced by Jaeger to study his well‐known Petersen Coloring Conjecture. More precisely, it is known that proving for every bridgeless cubic graph is equivalent to proving the Petersen Coloring Conjecture and then it implies, among others, Cycle Double Cover Conjecture and Berge‐Fulkerson Conjecture. Considering the larger class of all simple cubic graphs (not necessarily bridgeless), some interesting questions naturally arise. For instance, there exist simple cubic graphs, not bridgeless, with . In contrast, the known best general upper bound for was . Here, we improve it by proving that for any simple cubic graph , which is best possible. We obtain this result by proving the existence of specific nowhere zero ‐flows in ‐edge‐connected graphs.
Inappropriate sinus tachycardia or…something else?
Authors: Muresan Lucian , Le Bouar Ronan , Greciano Stephane , Muresan Crina , Schiau Serban , Cismaru Gabriel , Levy Jacques
Published: October 2019

We report the case of a 45‐year old female patient with a past medical history of rheumatoid arthritis who presented to our cardiology department with a suspicion of inappropriate sinus tachycardia. Echocardiography showed a nondilated left ventricle with a preserved ejection fraction. A careful reinterpretation of her 12‐lead ECG reoriented the diagnosis toward an incessant atrial tachycardia. The diagnosis was confirmed by an electrophysiologic study performed with an electro‐anatomic mapping system, which identified the origin of the tachycardia at the level of the right atrial appendage. Radiofrequency ablation of the ectopic focus eliminated the tachycardia and improved the patient's symptoms.
The effect of firm size, asset ownership, and market prices on regulatory violations
Authors: Scott Alex , Nyaga Gilbert N.
Published: October 2019

An individual's temptation to violate regulations for personal gain increases with the economic payoff to do so. Firms, however, adopt strategies to reduce undesirable behavior from their employees. This article examines how individuals change their propensity to violate regulations as the price for their services varies. We posit that individuals will commit more intentional, but not unintentional, violations as the payoff to do so increases, and that this effect will be moderated by the size of the firm for whom he or she works and whether the firm or the individual owns the assets used for production. To test our hypotheses, we link data from millions of inspections of truck driver logbooks with spot market prices observed over the same 4‐year period. We find that drivers who operate independently intentionally violate restrictions on their work hours more frequently when prices increase—violating 34% more frequently when prices are at their highest versus lowest—but larger firms and the firm's ownership of the assets reduce a driver's responsiveness to price changes. At the extreme, drivers for large asset‐owning firms are completely unresponsive to prices. Asset‐owning drivers are responsive to market prices, even for the largest firms.
Intervention as a research strategy
Authors: Oliva Rogelio
Published: October 2019

The Journal of Operations Management (JOM) has made design science central to its development strategy, creating a department to incubate papers using this methodology. An inaugural editorial published in 2016 called for papers with a generic design supported by adesign propositionthat provides pragmatic guidelines to bridge the gap between the case specific and the universal. In this article, I propose ways in which the scope of interventions can be expanded beyond the editorial's proposal to foster theoretical developments and better align with JOM's mission. I propose that, rather than focus on the design propositions, we explore the role that interventions (the ultimate manifestation of design science) can play in testing and developing theory (the ultimate goal of an academic endeavor). Taking as a point of departure the principles ofaction researchand the explanatory framework ofprocess theories, I propose two modes of research for leveraging interventions as a mechanism for testing existing theory and develop theories about organizational and system transformation. I illustrate the application of these two frameworks in the context of a previously published article.
Site formation processes at Donggutuo: a major Early Pleistocene site in the Nihewan Basin, North China
Authors: Jia Zhenxiu , Pei Shuwen , Benito‐Calvo Alfonso , Ma Dongdong , Sanchez‐Romero Laura , Wei Qi
Published: October 2019

Understanding site formation processes is crucial for interpreting archaeological context patterns and hominin behaviour as these affect the preserved condition of a site and the integrity of archaeological remains. The fluvio‐lacustrine sequences in the Nihewan Basin of North China are rich sources of early Pleistocene archaeological sites, which offer an important opportunity to investigate human evolution and adapted behaviours in East Asia. Although many Palaeolithic sites have been reported from the Nihewan Basin, North China, few of them focus on site formation processes before interpreting the hominin behaviour patterns. Here, we present a site formation study of four archaeological layers (Layers 6D, 6C, 6B and 6A) in Trench 1 from the Donggutuo (namely DGT‐T1) site in the Nihewan Basin with an age of 1.1 Ma. Through the study of sedimentary contexts, spatial distributions of artefacts and fossils, intra‐assemblage category ratios, debitage size distributions, lithic abrasion, artifact orientation and planar dip, our results show that all the layers had been disturbed by low‐energy sheet wash across the lake shore setting, but to differing extents. The post‐depositional disturbance caused by water decreased from the lower to the upper layers, from Layer 6D to Layer 6A. This indicates that the archaeological remains in DGT‐T1 have not been subject to significant natural modifications and are thus suitable for studying early hominin behaviour in North China.

Non‐invasive on‐site Raman study of polychrome and white enamelled glass artefacts in imitation of porcelain assigned to Bernard Perrot and his followers
Authors: Colomban Philippe , Kırmızı Burcu
Published: October 2019

Bernard Perrot produced sophisticated glass objects from ~1666–1709 in Orléans, particularly white enamelled artefacts and ruby glass. We present here the first non‐invasive Raman study of 16 polychrome and white enamelled glass artefacts that are assigned to Bernard Perrot or his followers. These glasses belong to the museum collections at Orléans and Sèvres in France. The prominent characteristic of these artefacts is their white bodies that were produced in imitation of porcelain. The small thickness of enamel applied to these glasses imposes the use of a high magnification (×200) long working distance microscope objective for Raman analysis. Pigments and opacifiers were identified, and the production technology was discussed. White opacification was found to be obtained by three compounds: calcium phosphate (bone opacification) for blown utensils, calcium antimonate for figurines, and cassiterite for thin enamels. The use of characteristic arsenic‐rich European cobalt was identified in the blue enamels with the characteristic Raman signature of lead arsenate apatite as observed for the 17th and 18th century French soft‐paste porcelains and Limoges enamels. The easy Raman detection of arsenic‐rich phases also allows on‐site identification of ruby glasses produced according to Perrot's technique (formation of Au° colloids by reaction initiated with an arsenic salt). The amount and crystallinity of calcium phosphate being variable appears to be a potential tool to discriminate between different production periods or workshops.
Annual Winter Site Fidelity of Barrow's Goldeneyes in the Pacific
Authors: Willie Megan , Esler Daniel , Boyd W. Sean , Bowman Timothy , Schamber Jason , Thompson Jonathan
Published: October 2019

Coastal regions on the Pacific north coast of North America provide important wintering habitat for many species of sea ducks. Although winter range and habitat preferences are well described for most species, fidelity to coastal wintering sites is generally undocumented. Fidelity is an important factor necessary for understanding interactions with coastal developments and activities and corresponding management strategies. We used data from Barrow's goldeneyes (Bucephala islandica), a sea duck that winters predominantly in nearshore habitats along the Pacific north coast, to investigate inter‐annual fidelity to, and intra‐annual fidelity within, coastal wintering sites. Between 2006 and 2015, we marked goldeneyes on breeding, molting, and wintering sites with satellite transmitters. We retained 4,931 locations in coastal habitats from 221 goldeneyes across 4 coastal regions for our analyses. These birds demonstrated high inter‐annual fidelity to coastal wintering sites; 75% of selected wintering sites were within 29 km of sites used the previous winter. Inter‐annual fidelity to wintering sites was similar between sex and age classes but differed by coastal region. Goldeneyes from southcentral Alaska, USA, expressed greater inter‐annual fidelity relative to birds from northern or southern British Columbia, Canada, and southeast Alaska. Goldeneyes also expressed high intra‐annual fidelity within wintering sites, with 75% of individuals averaging within‐season movements of ≤9 km. Intra‐annual fidelity was lesser for female than male goldeneyes but did not differ between hatch‐year and after‐hatch‐year birds. We found regional variation in intra‐annual fidelity, with goldeneyes from southcentral Alaska expressing greater intra‐annual fidelity compared to birds from other regions. High inter‐ and intra‐annual winter site fidelity by Barrow's goldeneyes suggests that, at a population level, habitat use is predictable and can be used to inform risk assessment or to evaluate factors affecting habitat choice. Also, low dispersal among wintering sites suggests that recovery from population perturbations, whether caused by natural or anthropogenic events, will be protracted. © 2019 The Wildlife Society.
Antecedents and outcomes of digital influencer endorsement: An exploratory study
Authors: Torres Pedro , Augusto Mário , Matos Marta
Published: October 2019

The advertising and marketing literature have established that celebrity endorsements constitute an effective way to enhance attitudes toward brands and increase purchase intents. However, there are no relevant studies on digital influencers. This study addresses the research gap by examining the effect of digital influencers' attractiveness and the effect of the congruence between a digital influencer and a brand on consumer attitudes and purchase intentions. By applying structural equation modeling to a sample of 307 followers of digital influencers, a model was tested and group analysis was performed for two categories (“entertainment & video games” and “fashion & beauty”). The results show that both brand attitudes and purchase intentions are influenced by the digital influencer's attractiveness (which includes both likeability and familiarity) and by the congruence between the digital influencer and the brand. This study makes several contributions to both theory and practice, which are highlighted in this paper.
Repair of the femoral nerve by two motor branches of the obturator nerve: A case report
Authors: Dubois Elodie , Popescu Ion‐Andrei , Sturbois Nachef Nadine , Teboul Frederic , Goubier Jean‐Noel
Published: October 2019

Complete femoral nerve palsies are uncommon but devastating injuries when they are caused by large nerve defects. Direct repair is usually not possible and nerve grafting renders uncertain outcomes. Recent studies proposed different peripheral nerve transfers as treatment strategies for large femoral nerve defects. We report a clinical application of a nerve transfer to reinnervate the quadriceps muscle with two motor branches of the obturator nerve in a 48 years‐old man that was diagnosed with a femoral nerve palsy after resection of a retroperitoneal schwannoma. The branches supplying the gracilis and adductor longus muscles were transferred to the motor branch of the femoral nerve to the quadriceps muscle at 6 months postinjury. At 34 months of follow‐up, knee extension was quoted M4. The presented nerve transfer may be feasible, technically simple, and renders good functional outcomes.

Authors: Song Kaijun , Luo Mou , Zhong Cuilin , Patience Shema R.
Published: October 2019

A novel extremely miniaturized dual‐mode defected ground structure (DGS) duplexer based on fractal structure is presented. To further reduce the circuit size, the novel DGS resonator with Hilbert fractal structure is used. The equivalent circuits of the presented duplexer are given to analyze and design the duplexer. An extremely miniaturized dual‐mode DGS‐resonator duplexer with the center frequencies of 1.9 GHz and 2.14 GHz, respectively is designed and assembled. The total size of the assembled duplexer is only 0.23λg × 0.1λg. The measured results are in good agreement with the simulated results.
Accelerated mono‐ and biexponential 3D‐T1ρ relaxation mapping of knee cartilage using golden angle radial acquisitions and compressed sensing
Authors: Zibetti Marcelo V. W. , Sharafi Azadeh , Otazo Ricardo , Regatte Ravinder R.
Published: October 2019

Purpose

To use golden‐angle radial sampling and compressed sensing (CS) for accelerating mono‐ and biexponential 3D spin‐lattice relaxation time in the rotating frame (T1ρ) mapping of knee cartilage.

Methods

Golden‐angle radial stack‐of‐stars and Cartesian 3D‐T1ρ‐weighted knee cartilage datasets (n= 12) were retrospectively undersampled by acceleration factors (AFs) 2‐10. CS‐based reconstruction using 8 different sparsifying transforms were compared for mono‐ and biexponential T1ρ‐mapping of knee cartilage, including spatio‐temporal finite differences, wavelets, dictionary from principal component analysis, and exponential decay models, and also low rank and low rank plus sparse models (L+S). Complex‐valued fitting was used and Marchenko‐Pastur principal component analysis filtering also tested.

Results

Most CS methods performed well for an AF of 2, with relative median normalized absolute deviation below 10% for monoexponential and biexponential mapping. For monoexponential mapping, radial sampling obtained a median normalized absolute deviation below 10% up to AF of 10, while Cartesian obtained this level of error only up to AF of 4. Radial sampling was also better with biexponential T1ρmapping, with median normalized absolute deviation below 10% up to AF of 6.

Conclusion

Golden‐angle radial acquisitions combined with CS outperformed Cartesian acquisitions for 3D‐T1ρmapping of knee cartilage, being it is a good alternative to Cartesian sampling for reducing scan time and/or improving image and mapping quality. The methods exponential decay models, spatio‐temporal finite differences, and low rank obtained the best results for radial sampling patterns.
Surface modification of reduced graphene oxide‐polyaniline nanotubes nanocomposites for improved supercapacitor electrodes
Authors: Devi Madhabi , Kumar Ashok
Published: October 2019

In the present work, irradiation with high energetic ions has been used for surface, structural, and morphological modifications of reduced graphene oxide (RGO) and polyaniline nanotubes (PAniNTs) nanocomposites with a view to enhance their electrochemical performance as supercapacitor electrode. High‐resolution transmission electron microscope micrographs depict defect induced fragmented morphology with stable inner hollow tubes up to a fluence of 2.2 × 1012 ions cm−2, above which drastic degradation of PAniNTs is observed. Irradiation induced annealing effects and structural disorder at varied irradiation fluences have been investigated by micro‐Raman spectroscopy. Formation of shorter PAniNTs of higher surface area due to generation of ion irradiation induced defects and their reorganization results in increased Brunauer‐Emmett‐Teller specific surface area and porosity. Surface energy and wettability of the electrodes increase upon ion irradiation, which improves electrode‐electrolyte interaction at the interface. Surface free energy calculations indicate increased concentration of polar groups on the nanocomposite electrode surface upon irradiation. Electrochemical performance studies indicate enhancement in specific capacitance and cyclic stability from 448 F g−1 and 89% for unirradiated nanocomposite to 482 F g−1 and 92%,, respectively, for the nanocomposite irradiated at 2.2 × 1012 ions cm−2 fluence, which is attributed to the increased surface energy and porosity upon irradiation giving rise to increased electrochemically active sites for charge storage in the electrode.
Chemically Functionalized Reduced Graphene Oxide as Additives in Polyethylene Composites for Space Applications

Published: October 2019

The discovery of radiation‐shielding materials remains a critical technology to enable long‐term space travel and extraterrestrial colonization. Hydrocarbon polymers, such as high‐density polyethylene (HDPE), are among the best radiation attenuators due to their rich H content and lightweight. Due to their simple chemical structure that lacks larger heteroatoms, HDPE is also resistant to numerous radiation‐induced degradation pathways that often limit the applicability of more sophisticated polymers. One drawback of hydrocarbon polymers is their inferior mechanical properties, such as tensile strength and impact toughness, relative to metals and other high‐performance polymer systems. In this report, we develop an alkylated reduced graphene oxide that is used as an additive to enhance the storage and tensile moduli of HDPE by 10–15% across the lunar temperature range. These additives outperform unmodified reduced graphene oxide by 30% due to better dispersion through the polymer matrix as observed by cross‐sectional scanning electron microscopy. POLYM. ENG.

Digital Divides in Political Participation: The Mediating Role of Social Media Self‐Efficacy and Privacy Concerns
Authors: Hoffmann Christian Pieter , Lutz Christoph
Published: October 2019

Scholarship on political participation and the Internet has found that Internet use may foster both online and offline political participation, while also finding pronounced inequalities in online political participation based on demographic and psychological characteristics. The article advances our theoretical understanding of how inequalities in online and offline political participation emerge through cognitive pathways, by applying social cognitive theory to conceptualize the relationship between environmental influences, cognition and behavior. Using survey data from 1,488 Internet users in Germany, we investigate how the cognitive dispositions of social media self‐efficacy and online privacy concerns mediate the effect of socio‐demographics on Internet use, and online as well as offline political participation. Results indicate that younger citizens are more likely to engage in online political participation, while older, more educated, and male citizens are more likely to engage in offline political participation. Internet use is positively associated with online political participation, which is closely related to offline participation. Self‐efficacy fully mediates the effect of education and gender on Internet use and online political participation. Thus, Internet use simultaneously amplifies and mitigates pre‐existing participation divides, depending on users’ cognitive dispositions.

Published: October 2019

Objective

The aim of this study is to describe a user‐centered (e.g., cancer survivors and clinicians) development process of an eHealth tool designed to facilitate self‐management of cancer survivorship follow‐up care.

Methods

Guided by Cognitive‐Social Health Information Processing (C‐SHIP) model and informed by core self‐management skills, we engaged in a user‐centered design process. In phase I, we conducted in‐depth interviews with survivors of breast (n = 33), prostate (n = 4), and colorectal (n = 6) cancers, and (n = 9) primary care providers to develop content and design of the web tool. Phase II utilized iterative user testing interviews (n = 9) to test the web‐based tool prototype. Data from both phases were independently coded using a template/content analytic approach.

Results

The top 5 functions identified in phase I for the web‐based platform included: (a) educational materials to learn and prepare for health encounters (80%); (b) questions for health providers (74%); (c) ability to track contact information of providers (67%); (d) provide general information (64%); and, (e) support information (62%). Users of the prototype reported patient burden, tool fatigue, introduction timing of the tool, relevance, and security/privacy as concerns in phase II.

Conclusions

This study demonstrates the value of using a theoretically informed and user‐centered design process to develop relevant and patient‐centered eHealth resources to support cancer survivorship. A larger study is needed to establish the efficacy of this eHealth tool as an intervention to improve adherence to follow‐up care guidelines.
Prehospital management of pediatric asthma patients in a large emergency medical services system
Authors: Ramgopal Sriram , Mazzarini Angelica , Martin‐Gill Christian , Owusu‐Ansah Sylvia
Published: October 2019

Background

Asthma is a common pediatric diagnosis for emergency medical services (EMS) transports, however there is a paucity of data on prehospital asthma management. The purpose of this study was to describe prehospital management of pediatric patients with suspected asthma exacerbation.

Methods

We conducted a retrospective review of electronic medical records from 24 ground EMS agencies in Southwestern Pennsylvania between 1 January 2014 to 31 December 2017. We identified patients 2 to 17 years with documented wheezing, excluding those with suspected anaphylaxis. Patients with documented respiratory distress were classified as severe asthma. We report descriptive statistics of demographics, vital signs, and management including administration of medications and performance of procedures.

Results

Of 19 246 pediatric transports, 1078 (5.6%) patients had wheezing. Of these, 532 (49%) met criteria for severe asthma. Patients with severe asthma were more likely to be adolescents compared to those with nonsevere asthma (49.6% vs 6%; P < .001). While rates of intravenous methylprednisolone administration were higher in patients with severe asthma (68/532, 12.8%) compared to those with nonsevere asthma (13/546, 2.4%; P < .001), overall use of steroids was low (7.5%). Other therapies provided included albuterol (n = 699, 64.8%), ipratropium bromide (n = 271, 25.1%), and oxygen (n = 280, 26.0%). One hundred eighty patients (16.7%) received a peripheral IV line. Two patients (0.4%) were given continuous positive airway pressure.

Conclusion

Approximately 6% of pediatric EMS transports are for asthma. Steroid usage was low in even those with severe asthma, representing an area of process improvement. These data provide a baseline to future research to identify interventions that may improve outcomes.
Investigating the productive uses of uncertainty in knowledge co‐creation practices
Authors: Archambeault Jean
Published: October 2019

This poster presents results from an ongoing exploratory research study, which uses a participant observation methodology to investigate the productive uses of uncertainty in fostering knowledge emergence. Recent research suggests that introducing uncertainty can be a productive resource to facilitate the emergence of knowledge in co‐creation practices. While recognizing productive traits to uncertainty is not new in information science, how uncertainty can be deliberately introduced, as a productive resource, remains generally unnoticed. This study extends previous research in this area by further detailing the use of uncertainty and by constituting a foray into investigating information practices in collective knowledge creation environments. Findings suggest that introducing uncertainty aims at inducing a state of unknowability to erode certainty, disrupt entrained thinking and processual constraints, and decompartmentalize disciplinary boundaries that inhibit knowledge emergence. The experiences of relational engagement, joint advantage and mutual transformation arose as conditions conducive to using uncertainty for knowledge emergence.

Examination of online information search stopping behaviors and stopping rules by task type
Authors: Dedema  , Liu Chang
Published: October 2019

This poster aims to understand how task type could influence when people would stop searching and what stopping rules people would use in the following three stopping behaviors: query stopping, read stopping, and task stopping during online information search. We conducted a pilot user experiment with four participants; each performed two different types of search tasks. The results show two different patterns of stopping behavior on well‐structured and decomposable tasks and poorly structured and indecomposable tasks: sequential mode, and simultaneous mode; and people use different stopping rules in three stopping behaviors.

Published: October 2019

Along with the massive increase of academic full texts, users now have a growing need for fine‐grained academic literature retrieval. However, few studies have attempted to build domain knowledge retrieval system for academic literature in information science. Compared with other disciplines, information science pays more attention to the domain knowledge entities sequence including data resources, models and software. To fill the gap, this paper use academic full texts from JASIST. Using SVM, Text‐CNN, Bi‐LSTM and BERT to extract the knowledge entities sequence including data resource, model, software. The highest Precision, Recall and F1 are 92.45%, 93.86% and 93.14%, respectively. And the knowledge entity sequence indexing system is built based on the extracted knowledge entities sequences. It was found that the MRR score of the knowledge entities sequence retrieval system was higher by 13% as compared with the full text retrieval system.

Does citation content of references from different disciplines demonstrate same distribution pattern?
Authors: Liu Lifan , Wang Yuzhuo , Zhang Chengzhi
Published: October 2019

Citation in academic articles is an important expression of knowledge flow between different disciplines. Analysis of citation content of references from different disciplines can help scholars to understand the role of various disciplines in knowledge flow. This study identifies the discipline of references in academic articles, and then explores the distribution pattern, including cited frequency and cited position (different type of section), of citation content of these references from different disciplines. Finally, we conclude that distribution patterns of different disciplines are different in knowledge flow. Although most references come from natural science, the humanities and social sciences still play an important role in the introduction and background. Basic disciplines like Mathematics are the main providers of methods, and some disciplines relevant to the research topic, like Nursing and Medicine in PLOS, provide more support for the results part of articles.

What will influence users' knowledge sharing behavior in the social Q&A community?
Authors: Song Zhijun , Dong Qingxing , Cao Gaohui , Chen Ye
Published: October 2019

The social Q&A community, as one of the most popular platforms of knowledge sharing, now faces user churn and slower growth in new active user numbers. To some extent, the main problem concealing in the decrease of growth is the lack of knowledge contribution from the users, which is the most attractive function of the social Q&A community. Thus the key point of tackling this problem is to explore which factors influence users' knowledge sharing behavior. Based on social capital theory and social exchange theory, this study constructs a regression model and collects empirical data to investigate the influencing factors of users' knowledge sharing behavior. It is found that the increment of users' centrality, harvest and users' trust toward the community lead to more and better shared‐knowledge. However, the increase in users' reputation has a significant negative impact on the quantity and quality of their behavior. The theoretical and practical implications derived from the findings are further discussed.

Moving from assumptions to evidence: Assessing quality in online courses in a master of information program
Authors: Stoerger Sharon , Pavlovsky Lilia
Published: October 2019

Creating opportunities that encourage and support student learning is at the heart of what instructors do. At the same time, LIS programs are attempting to keep up with and navigate a rapidly changing educational landscape. The types of students who enroll in and graduate from our programs are becoming more diverse, as are their needs. This also is true of the employers who are hiring our graduates. Further, concerns have been raised about student debt and the value of the degree. Linking these issues to the quality of the program and more specifically the courses themselves is key. This poster discusses an attempt to develop a proactive structure to formally assess the quality of the online courses in the Master of Information program at Rutgers, The State University of New Jersey.

Published: October 2019

This study explored biomedical researchers' Research Data Management (RDM) practices and investigated how institute and professional services support their practices through the RDM processes with a case of NIH. It was found that institutional information technology (IT) and library services are focused on certain stages of RDM processes. Also, it was found that having a close collaboration among service units within an institute is important to maximize their resources for services, reduce duplicated services, and publicize their services to a wider range of users.
#Cyberbullying in the digital age: Exploring people's opinions with text mining
Authors: Tahamtan Iman , Huang Li‐Min
Published: October 2019

This study used text mining to investigate people's insights about cyberbullying. English‐language tweets were collected and analyzed by R software. Our analysis demonstrated three major themes: (a) the major actions that needed to be taken into consideration (e.g. guiding parents and teachers to cyberbullying prevention, funding schools to cope with cyberbullying), (b) certain events that were important to people (e.g. the Michigan cyberbullying law), and (c) people's major concerns in this regard (e.g. mental health issues among students). Parents and teachers have an important role in educating, informing, warning, preventing, and protecting against cyberbullying behaviors. The frequency of negative sentiments was almost 2.45 times more than positive sentiments.

Authors: Wang Shengang , Lee Hyun Seung , Choi Wonchan
Published: October 2019

With advances in mobile health (mHealth) technology and growing ownership of smartphones, mHealth applications have great potential to support patients' self‐management of chronic diseases such as diabetes and hypertension. Informative consumer reviews on app stores (e.g., Google Play) are a useful source of information for app developers to understand users' needs and for users to select a pertinent app over similar alternatives. This poster reports preliminary findings of a study that explores factors affecting the informativeness of consumer reviews using a feature‐centered rating scale. The results show that consumer ratings and the length of consumer reviews are both correlated with informativeness. These findings will contribute to filtering informative reviews for future in‐depth analyses of app features.
Order effect on relevance judgment: An exploratory study on the detection of quantum interference
Authors: Wang Zhihong , Cao Shujin
Published: October 2019

This poster explores the existence of order effect on relevance judgment, especially the interference of one document on the other while evaluating the relevance. A between‐subject experiment with 78 undergraduate students was reported. The results demonstrated the statistically significant existence of order effect for some topics and spotted quantum interference while evaluating the relevance of documents. This preliminary study provides insights into how documents' evaluation is contextualized and interdependent with each other. It has some implications for future theoretical and practical research on the human cognitive aspect of relevance judgment in information retrieval.

Vulnerability and meeting the needs of people experiencing homelessness in public libraries
Authors: Williams Rachel D.
Published: October 2019

This study examines how public library workers navigate professional boundaries when providing information services to people experiencing homelessness. Relying on interviews with twenty‐four library staff at three public library systems in the Midwest United States and Gieryn's (1983) boundary work theory, this project focuses on the information public librarians provide to people experiencing homelessness. It also argues that public librarians navigate tensions in professional and personal boundaries, and that some of these tensions can be attributed to perceptions of vulnerability in both themselves and in the patrons they assist. The paper concludes by making arguments to consider the importance of self‐care and building resilience in the profession of public librarianship. It also suggests the value of partnerships that enable public library staff to re‐conceptualize what their professional roles entail.

Authors: Wu Dan , Xu Hao , Fan Shu
Published: October 2019

Nowadays, consumers can conveniently access and use health information from online health consultation platforms. It is important to identify the patterns of consumers' multi‐source health information acquisition in the circumstance of online health consultation. However, little research has been done in this area. Focusing on such a target, data from an online health consultation platform was taken as an example. 869 cases from the platform were crawled, and a grounded theory research methodology was adopted. According to the coding results, the author found eight patterns of consumers' health information acquisition. This study broadens our understanding of the behavioral pattern of attaining multi‐source health information, enriching the field of health information search behavior.

Stages of change in smoking cessation and health information behavior
Authors: Yi Yong Jeong , Nam Seo Jin
Published: October 2019

The study aimed at investigating the health information behavior of consumers who attempt to quit smoking and analyzing the effects of the information obtained on health behavior changes. The researchers interviewed 35 college students who were in different stages of smoking cessation for seven months. The study participants in precontemplation or contemplation stages tended to demonstrate passive information‐seeking modes, whereas the participants in more advanced stages tended to perform active and direct information‐seeking. The participants in these stages tended to search more for professional information or firsthand experiences related to pros and cons as well as strategies for smoking cessation. The findings identified the different cognitive or affective effects of the information on individuals at the discrete stages. In particular, the study bridges the gaps of the research that focuses on information behavior related to changes of addictive health behavior by applying the transtheoretical model (TTM) to the concepts of health information behavior.

Influence of course type and assignment features on students' information seeking behaviors
Authors: Zhang Yao , Liu Chang
Published: October 2019

Exploring students' information seeking behavior and its influencing factors during assignment completion process can help promote teaching and learning performance. In this study, we collect college students' assignment information and their information seeking behaviors during assignment completion process through questionnaires. In total we have data of 162 courses ranging from a variety of majors. We analyzed the relationship among course type, assignment features and information behaviors during assignment completion process. We found students' information sources election is closely related to course type and assignment cognitive complexity, and their preferred information type is also related to assignment type. Results also indicate that assignments from professional compulsory courses emphasize more on basic cognitive learning, while other courses more on advanced cognitive learning. These findings are useful for course instructors to improve students' information literacy through assignments.
How did people feel during the Zika virus breakout? A sentiment analysis of Zika virus related posts on Yahoo! Answers
Authors: Zhao Yuehua , Chen Ye , Zhang Jin , Dong Qingxing , Cao Gaohui , Zhang Zhaoyang
Published: October 2019

A sudden outbreak of the Zika virus led to public panic and discussion on social Q&A forums. Most research studies concentrated on what the public discussed about the Zika virus. However, how they felt during the Zika virus outbreak reflects the emotional stability of the public, which has a positive significance in public health monitoring, intervention and service. For this paper, we conducted a sentiment analysis of Zika‐related posts on Yahoo! Answers during the outbreak of the Zika virus to investigate how emotions of the public changed overtime and if users' emotions could be influenced by others. It was found that significantly more negative emotions appeared when an outbreak started in Brazil, yet people's reactions became milder afterwards. Besides, a small positive correlation between the sentiment characteristics of the questions and the received answers implies the exchanges of emotions between questioners and answerers.
