How do Chinese researchers use research information management systems?: An exploratory study
Authors: Wu Shuheng , Stvilia Besiki , Lee Dong Joon 
Published: October 2017

ABSTRACTThis poster presents how Chinese researchers use research information management (RIM) systems (e.g., ResearchGate, Google Scholar). Findings include a typology of activities in which Chinese researchers engage in RIM systems. The findings indicate that obtaining English papers and connecting with scholars from other countries motivate Chinese researchers to use specific RIM systems, while the language barrier and the Great Firewall of China discourage them to use or engage in those systems.
Music literature indexing: A comparison between users' free‐text queries and controlled vocabularies
Authors: Wu Shuheng , Fan Yun 
Published: October 2017

ABSTRACTSubject indexing of music literature is known to be difficult because of language barriers and the vocabulary problem. Prior research has validated the necessity of indexing documents based on users' search queries. This study examined the characteristics of users' free‐text queries created in a music literature database (RILM) and compared those queries with the controlled vocabularies used by the database. This poster presents a typology of 11 categories of user‐created search terms identified in RILM. The findings indicate that the controlled vocabularies used by RILM align well with the user search terms. Based on the findings, suggestions are offered to enhance and improve the controlled vocabularies for music literature indexing.
Towards understanding consumers' quality evaluation of online health information: A case study
Authors: Ye Zequn , Gwizdka Jacek , Lopes Carla Teixeira , Zhang Yan 
Published: October 2017

ABSTRACTWe present a case study of quality evaluation of online health information. Two participants were selected from a health information search (HIS) study, in which we are investigating consumers' evaluation of the quality of online health information. The selected cases offered a rare example of two almost exactly opposite eye‐movement patterns on the same webpage. To better understand the differences in these patterns, we investigated participants' cognitive evaluation processes by examining their textual explanations collected in post‐task questionnaires and verbal explanations collected in the retrospective think‐aloud (RTA) sessions. We discuss how eHealth literacy and personality scores may be related to the behavioral differences. The findings of this case study inform the formulation of hypotheses for full data analysis of the HIS study, as well as future research addressing behavior patterns and factors affecting consumers' quality evaluation of online health information.
Exploring text classification of social support in online health communities for people who are D/deaf and hard of hearing

Published: October 2017

ABSTRACTDue to the social oppressions from the mainstream society, social support becomes fundamental for people who are D/deaf and hard of hearing (D/hh) to exchange information within their own community. We aim to examine the support content of messages and how support processes become established by exploring the interactions within a D/hh discussion forum, AllDeaf.com, which is one of the leading online communities for D/hh. In this pilot study, we first employed content analysis to code discussion posts using the Social Support Behavior Code. Two authors collaboratively coded a random sample of 25 threads and 632 posts. Informational support was observed as the most frequently exchanged type of social support for people who are D/hh. Then we identified social support features used for future text classification task. Our preliminary qualitative findings indicated that the linguistic and lexical features have the potential to support automated feature identification and social support classification typology with text mining techniques
Machine reading for relationships between autism research and the media
Authors: Ding Ying , Wang Fang , Wang Xiaoyu , Zhai Yujia 
Published: October 2017

ABSTRACTAutism represents a broad group of developmental disorders characterized by impaired social interactions. It has attracted widespread concern in academia and media. The reported causes of autism have an enormous impact on the people's opinion about autistic patients and various treatments from scientific literature and media news. In this study, we use open information extraction (OIE), a machine reading technique, to automatically extract causal relationships from autism researches and news reports. We explored the differences between the scientific literature and news about the reported etiologies with respect to autism. As a result, we find that scientific papers clearly emphasize physical and biological factors, while the media emphasizes social factors as the perceived cause of autism.
Decomposing the Twitter data stream in healthcare: An information theory perspective
Authors: Zhang Yuan , Chang Hsia‐Ching 
Published: October 2017

ABSTRACTRecent research using Twitter as an information communication channel has shown how event organizers convey and disseminate their agendas across industries and disciplines. However, little research has been carried out on the user's choice of information components when composing a tweet through the lens of information theory. This research employs a comparative case study to examine how medical‐terminology hashtags and corresponding lay‐language hashtags have been used to help to communicate healthcare messages on the Twitter platform. The main result of this case study revealed patterns that both retweeting behavior and the use of a variety of components to construct a tweet contribute to higher entropy values which imply that these are more informative ways to communicate healthcare messages.
Predictive value of epithelial‐mesenchymal‐transition (EMT) signature and PARP‐1 in prostate cancer radioresistance

Published: October 2017

IntroductionEpithelial‐mesenchymal‐transition (EMT) has been previously identified as a contributor to prostate cancer progression to metastasis and therapeutic resistance to antiandrogens and radiotherapy. In this study we conducted a retrospective analysis to investigate the significance of radiation‐induced EMT and consequential changes to the tumor microenvironment in biochemical recurrence and response to radiotherapy in prostate cancer patients.MethodsExpression profiling and localization for EMT effectors, E‐Cadherin, N‐Cadherin, β‐catenin and Vimentin was assessed in human prostate tumor specimens pre‐ and post‐radiotherapy and correlated with biochemical recurrence. In addition, immunoreactivity of the DNA repair enzyme, polymerase (PARP‐1) and the cytoskeletal‐remodeling regulator, cofilin was evaluated in prostate tumor specimens pre‐ and post‐radiotherapy and correlated with pre‐treatment prostate‐specific antigen levels (PSA).ResultsOur findings identified that characteristic changes associated with the EMT phenotype and its reversal to mesenchymal‐epithelial‐transition (MET) within the tumor microenvironment correlate with biochemical recurrence and resistance to radiotherapy among prostate cancer patients. Moreover, elevated PARP‐1 expression among the tumor cells undergoing EMT implicates that DNA repair mechanisms may potentially reverse the cytotoxic effects of radiotherapy‐induced DNA breaks.ConclusionsOur results suggest that EMT programming effectors, integrated with the actin cytoskeleton regulator cofilin and mesenchymal PARP‐1 expression profile provide a signature of potential predictive significance of therapeutic response to radiotherapy in a subset of prostate cancer patients.

AbstractBACKGROUNDThe application of synthetic insecticides remains the most used tool for the management of spotted‐wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae). However, management of this pest in the organic production of soft‐skinned fruits is a complex task due to the restricted number of registered products. Here, we assess the toxicity of lime sulfur and evaluate whether lime sulfur‐treated strawberry plants affected the oviposition and development of D. suzukii.RESULTSLime sulfur exhibited adequate toxicity to D. suzukii (LC50 = 26.6 mL L−1) without phytotoxicity to strawberry plants. When D. suzukii females were exposed to lime sulfur‐treated plants in no‐choice bioassays, oviposition was significantly (t‐test, P < 0.05) reduced compared with that on untreated plants. In free‐choice bioassays, D. suzukii females laid significantly (paired t‐test, P < 0.05) more eggs on untreated plants. Furthermore, in the free‐choice bioassays, immature development was slower for adults that originated from eggs laid on lime sulfur‐treated plants than from those laid on untreated plants.CONCLUSIONSLime sulfur showed adequate control and, therefore, has potential for use as a management tool against D. suzukii infestations in organic production systems. This old, alternative insecticide preparation not only caused adult fly mortality, but also reduced the number of eggs laid on lime sulfur‐treated plants. © 2017 Society of Chemical Industry
Experimental design matters for statistical analysis: how to handle blocking
Authors: Jensen Signe M , Schaarschmidt Frank , Onofri Andrea , Ritz Christian 
Published: October 2017

AbstractBACKGROUNDNowadays, evaluation of the effects of pesticides often relies on experimental designs that involve multiple concentrations of the pesticide of interest or multiple pesticides at specific comparable concentrations and, possibly, secondary factors of interest. Unfortunately, the experimental design is often more or less neglected when analysing data. Two data examples were analysed using different modelling strategies. First, in a randomized complete block design, mean heights of maize treated with a herbicide and one of several adjuvants were compared. Second, translocation of an insecticide applied to maize as a seed treatment was evaluated using incomplete data from an unbalanced design with several layers of hierarchical sampling. Extensive simulations were carried out to further substantiate the effects of different modelling strategies.RESULTSIt was shown that results from suboptimal approaches (two‐sample t‐tests and ordinary ANOVA assuming independent observations) may be both quantitatively and qualitatively different from the results obtained using an appropriate linear mixed model. The simulations demonstrated that the different approaches may lead to differences in coverage percentages of confidence intervals and type 1 error rates, confirming that misleading conclusions can easily happen when an inappropriate statistical approach is chosen.CONCLUSIONTo ensure that experimental data are summarized appropriately, avoiding misleading conclusions, the experimental design should duly be reflected in the choice of statistical approaches and models. We recommend that author guidelines should explicitly point out that authors need to indicate how the statistical analysis reflects the experimental design. © 2017 Society of Chemical Industry
An asymmetric Lyapunov function for linear systems with asymmetric actuator saturation
Authors: Li Yuanlong , Lin Zongli 
Published: October 2017

SummaryThis paper proposes an asymmetric Lyapunov function approach to the estimation of the domain of attraction and the domain with a guaranteed regional
gain for a linear system subject to asymmetric actuator saturation. Depending on the sign of each of the m inputs, the input space is divided into 2m regions. In each region, the linear system with asymmetrically saturated inputs can be expressed as a linear system with symmetric dead zone. A quadratic function of the augmented state vector containing the system state and the symmetric dead‐zone function is constructed for each region. From these quadratic functions, an asymmetric Lyapunov function is composed. Furthermore, based on the special properties of the intersections between regions, 2 generalized asymmetric Lyapunov functions are proposed that lead to reduced conservativeness. A set of conditions are established under which the level sets of these asymmetric Lyapunov functions are contractively invariant and are thus estimates of the domain of attraction. Another set of conditions are derived under which the level sets are subsets of the domain with a guaranteed regional
gain. Based on these conditions, LMI‐based optimization problems are formulated and solved to obtain the largest level sets as the estimates of the domain of attraction and of the domain with a guaranteed regional
gain. Simulation results demonstrate the effectiveness of the proposed approach.

Published: October 2017

Globally, many rivers are experiencing declining water quality, for example, with altered levels of sediments, salts, and nutrients. Effective water quality management requires a sound understanding of how and why water quality differs across space, both within and between river catchments. Land cover, land use, land management, atmospheric deposition, geology and soil type, climate, topography, and catchment hydrology are the key features of a catchment that affect: (1) the amount of suspended sediment, nutrient, and salt concentrations in catchments (i.e., the source), (2) the mobilization ,and (3) the delivery of these constituents to receiving waters. There are, however, complexities in the relationship between landscape characteristics and stream water quality. The strength of this relationship can be influenced by the distance and spatial arrangement of constituent sources within the catchment, cross correlations between landscape characteristics, and seasonality. A knowledge gap that should be addressed in future studies is that of interactions and cross correlations between landscape characteristics. There is currently limited understanding of how the relationships between landscape characteristics and water quality responses can shift based on the other characteristics of the catchment. Understanding the many forces driving stream water quality and the complexities and interactions in these forces is necessary for the development of successful water quality management strategies. This knowledge could be used to develop predictive models, which would aid in forecasting of riverine water quality.

Published: October 2017

AbstractIntroductionA physician shortage is on the horizon, and surgeons are particularly vulnerable due to attrition. Reduced job satisfaction leads to increased job turnover and earlier retirement. The purpose of this study is to delineate the risk factors that contribute to reduced job satisfaction.MethodsA cross‐sectional survey of US surgeons was conducted from September 2016 to May 2017. Screening for job satisfaction was performed using the abridged Job in General scale. Respondents were grouped into more and less satisfied using the median split. Twenty‐five potential risk factors were examined that included demographic, occupational, psychological, wellness, and work‐environment variables.ResultsOverall, 993 respondents were grouped into more satisfied (n = 502) and less satisfied (n = 491) cohorts. Of the demographic variables, female gender and younger age were associated with decreased job satisfaction (p = 0.003 and p = 0.008). Most occupational variables (specialty, experience, academics, practice size, payment model) were not significant. However, increased average hours worked correlated with less satisfaction (p = 0.008). Posttraumatic stress disorder, burnout, wellness, all eight work‐environment variables, and unhappiness with career choice were linked to reduced job satisfaction (p = 0.001).ConclusionA surgeon shortage has serious implications for health care. Job satisfaction is associated with physician retention. Our results suggest women and younger surgeons may be at increased risk for job dissatisfaction. Targeted work‐environment interventions to reduce work‐hours, improve hospital culture, and provide adequate financial reimbursement may promote job satisfaction and wellness.

AbstractBackgroundLack of access to emergency and essential surgery is widespread in low‐ and middle‐income countries. Scarce anesthesia services contribute to this unmet need. The aim of this study was to evaluate the safety and feasibility of the Every Second Matters for Emergency and Essential Surgery‐Ketamine (ESM‐Ketamine) package for emergency and essential procedures when no anesthetist was available.MethodsFrom November 2013 to September 2017, the ESM‐Ketamine package was used for patients requiring emergency or life‐improving surgeries in fifteen selected facilities across Kenya when no anesthetist was available. A mixed‐methods approach was used to assess safety and feasibility of the ESM‐Ketamine package, including demand, acceptability, and practicality. The primary outcome was ketamine‐related adverse events. Key‐informant interviews captured perceptions of providers, hospital administrators, and surgeons/proceduralists.ResultsNon‐anesthetist mid‐level providers used ESM‐Ketamine for 1216 surgical procedures across the fifteen study facilities. The median ketamine dose was 2.1 mg/kg. Brief (<30 s) oxygen desaturations occurred in 39 patients (3%), and prolonged (>30 s) oxygen desaturations occurred in seven patients (0.6%). There were 157 (13%) reported cases of hallucinations and agitation which were treated with diazepam. All patients recovered uneventfully, and no ketamine‐related deaths were reported. Twenty‐seven key‐informant interviews showed strong support for the program with four main themes: financial considerations, provision of services, staff impact, and scaling considerations.ConclusionsThe ESM‐Ketamine package appears safe and feasible and is capable of expanding access to emergency and essential surgeries in rural Kenya when no anesthetist is available.

Abstract
Reaching high density in PM steels is important for high-performance applications. In this study, liquid phase sintering of PM steels by adding gas-atomized Ni-Mn-B master alloy was investigated for enhancing the density levels of Fe- and Mo- prealloyed steel powder compacts. The results indicated that liquid formation occurs in two stages, beginning with the master alloy melting (LP-1) below and eutectic phase formation (LP-2) above 1373 K (1100 °C). Mo and C addition revealed a significant influence on the LP-2 temperatures and hence on the final densification behavior and mechanical properties. Microstructural embrittlement occurs with the formation of continuous boride networks along the grain boundaries, and its severity increases with carbon addition, especially for 2.5 wt pct of master alloy content. Sintering behavior, along with liquid generation, microstructural characteristics, and mechanical testing revealed that the reduced master alloy content from 2.5 to 1.5 wt pct (reaching overall boron content from 0.2 to 0.12 wt pct) was necessary for obtaining good ductility with better mechanical properties. Sintering with Ni-Mn-B master alloy enables the sintering activation by liquid phase formation in two stages to attain high density in PM steels suitable for high-performance applications.
Recurrent patterns of microdiversity in a temperate coastal marine environment

Published: October 2017

AbstractTemperate coastal marine environments are replete with complex biotic and abiotic interactions that are amplified during spring and summer phytoplankton blooms. During these events, heterotrophic bacterioplankton respond to successional releases of dissolved organic matter as algal cells are lysed. Annual seasonal shifts in the community composition of free-living bacterioplankton follow broadly predictable patterns, but whether similar communities respond each year to bloom disturbance events remains unknown owing to a lack of data sets, employing high-frequency sampling over multiple years. We capture the fine-scale microdiversity of these events with weekly sampling using a high-resolution method to discriminate 16S ribosomal RNA gene amplicons that are &gt;99% identical. Furthermore, we used 2 complete years of data to facilitate identification of recurrent sub-networks of co-varying microbes. We demonstrate that despite inter-annual variation in phytoplankton blooms and despite the dynamism of a coastal–oceanic transition zone, patterns of microdiversity are recurrent during both bloom and non-bloom conditions. Sub-networks of co-occurring microbes identified reveal that correlation structures between community members appear quite stable in a seasonally driven response to oligotrophic and eutrophic conditions.
