Flames of Justice in the Virtual Garden: A Preliminary Analysis of Tweets around the Death of an Indian Celebrity
Authors: Sengupta Subhasree , Tacheva Jasmina 
Published: October 2021

AbstractSocial media, particularly Twitter, is a powerful medium for expression and discussion across regions and communities in the world today. Using hashtags, a powerful and popular affordance of Twitter, several forms of civic engagement and online social campaigns emerge and inform public discourse. Although several prior studies have investigated the rhetorical impact of such narrative movements on Twitter, an important consideration lies in understanding the structural forms that such narratives take depending on the context and regional culture where the movement originates. To this end, this study embarks on a preliminary analysis of 150 tweets related to calls of action and social justice in the aftermath of the death of a popular Indian movie star. The analysis reveals a diverse spectrum of themes ranging from expressions of loss and grief to critiques of institutions and mechanisms of power. Parallel but powerful themes also demonstrate attempts to nurture and embolden the campaign. The aim of this analysis is to provide insights into how such channels of discourse might be designed to create a medium of freedom of expression and foster safe spaces for civic engagement.

Authors: Sun Yinying , Lou Wen , Zhang Lin 
Published: October 2021

AbstractThe purpose of this study is to explore the gender distribution of researchers in the field of gender studies. We used bibliometrics methods on a dataset of gender studies from Web of Science between 2007 and 2019. The results show that unlike other fields in scientific communities, gender studies are dominated by female researchers. The majorities of gender study communities come from North America and Europe, which are both dominated by female researchers.
Students' Motivations for Not Sharing Rumours during the COVID‐19 Pandemic in Singapore
Authors: Tan Minying , Chua Alton Y.K. 
Published: October 2021

AbstractThe COVID‐19 pandemic has underscored the importance of curbing harmful misinformation and prompted legislation against fake news. Based on the case of the COVID‐19 pandemic in Singapore, this study investigated motivations behind college students' decisions not to share rumours on WhatsApp. Responses from 75 participants were collected through an anonymous online survey in July 2020. The findings suggest that during an infectious disease outbreak, students' decisions not to share rumours were motivated by concerns related to information quality rather than the fear of regulatory punishment.
Theory into Practice: Information Behavior in Pre‐Service Education for Information Service Roles
Authors: VanScoy Amy , Julien Heidi , Harding Alison 
Published: October 2021

AbstractThis poster will present the results of an online survey of instructors of reference and information services courses in North American programs preparing information service professionals for practice. The survey explores instructors' decisions about incorporating information behavior theories, models, and concepts into their courses, as well as their perspectives on the appropriate balance between theoretical and practical course content. The survey constitutes phase three of a study with two previous phases: a content analysis of course syllabi for these courses and interviews with course instructors. Study results to date show that variation in instructors' information behavior expertise, and in their discretion to modify course content, lead to significant disparity in theory content. The findings suggest opportunities to educate course instructors in information behavior content, and to strengthen theoretical content in courses, which would better prepare future information service professionals to provide more effective service.
Factors for Online Identity Falsification among Israeli Students in the Era of COVID‐19
Authors: Weinberger Maor , Bouhnik Dan 
Published: October 2021

AbstractThis research investigates the main factors which motivate users to provide falsified details upon website registration, and identifies the types of personal details that are most prone for falsification. In addition, we predict the tendency for identity falsification by examining various factors, such as: privacy concern and socio‐demographic factors. We also relate those issues to the contemporaneous COVID‐19 pandemic and examine its influence on privacy concerns and the willingness to expose personal details. To this end, a user study was carried out among 245 students of the Israeli academia, via a quantitative method using online closed‐ended questionnaires. We found that privacy‐related factors are the most prevalent for identity falsification. In addition, the regression showed the higher the privacy concerns rates, the higher chance for identity falsification. It seems that the COVID‐19 pandemic increased privacy concerns among online users, which may even increase the tendency of the examined behavior.
What Does the Literature Tell Us? Reviewing Literature Reviews on Information Behavior
Authors: Zhang Xiaoqian , Bartlett Joan C. 
Published: October 2021

ABSTRACTMany reviews on information behavior have been published to date, however little research has been done to understand these reviews. To fill this gap, this poster reviewed 96 literature reviews in this field. The preliminary analysis uncovers several characteristics of literature reviews on information behavior: (1) these reviews have discussed two transformations in the history of information behavior; (2) current literature reviews focus on specialized areas of information behavior; (3) literature reviews have highlighted different issues in information behavior research, such as the quality of information and the practical contributions of research; (4) literature reviews keep summarizing and developing theories and models of information behavior. This preliminary analysis provides an overview of 30 years of literature reviews, showing what existing literature reviews have done. It identifies trends in information behavior research and may inspire what kinds of literature reviews are needed in the future.

Published: October 2021

AbstractThe COVID‐19 pandemic has led to the closure of schools around the world. When children study online, parents are concerned about the impact of increased screen time on their children's physical and mental health. This poster reports results from a qualitative study of Chinese preteens’ Internet use and parental mediation during the COVID‐19 pandemic. Through interviews with eight parents of primary school students aged from 10 to 12, we found several problems with preteens’ Internet use, posing challenges for parental mediation. Parents have adopted stricter restrictive mediation strategies to reduce the impact of Internet addiction and implemented co‐use strategies to help preteens adapt to online learning.

Published: October 2021

AbstractAcademic conferences can promote academic exchanges among researchers. As the core of academic conferences, they inject soul into academic conferences. Here, we put forward the evaluation of researchers' academic conference active degree from the perspective of participation. This paper mainly proposes to apply the “h‐index” and the “p‐index” to the active degree evaluation of researchers, which is a particularly simple and useful method to describe the scientific output of a researcher in academic meetings. The relevant indices are extended to the participation indices, forming the p‐index of participation. Introduce the participation rate to improve the original h‐index and form the h‐index of participation. The evaluation effect of each index is analyzed from the consistency, difference and correlation between them. The results support the conclusion that the p(p)‐index can well reflect the value of researchers' lifetime contribution, and the h(p)‐index can reflect the degree of loyalty of researchers better.

Authors: Zhao Yuehua , Wang Hao , Deng Sanhong , Chen Ye 
Published: October 2021

AbstractOnline support groups offer a new way to users to communicate with others regarding certain health issues. Taking autism‐related support groups on Facebook as an example, we examine whether the expressed emotions differ between female and male users in online health‐related support groups and whether such gender disparity varied based on the topics of the groups. Experimental results reveal a significant gender difference of expressed emotions in the groups. We find that female users tended to express more positive emotions in the group discussions than the male group members did. In addition, users appeared to express different sentiments within the groups focused on various topics. Male users tend to convey more negative emotions in the group that related to treatment, while female users were more positive when posted in the research‐related group than male users were. This study is beneficial for tracking and moderating the emotional environment in online support groups.
Hidden Markov model based filtering for singular semi‐Markov jump systems
Authors: Li Siyi , Lian Jie , Gong Liang 
Published: October 2021

AbstractThis article investigates the hidden Markov model based filter design problem for the singular semi‐Markov jump systems (SSMJSs). The considered semi‐Markov process is a generalization of Markov process, which can eliminate the restriction on the exponential distribution of sojourn time. Besides, the hidden Markov model based filter is introduced to tackle the asynchronous phenomenons occurred between the system modes and filter modes. To ensure the stochastic stability of the SSMJSs and derive solvable filter parameters, a filter design technic is constructed. First, the direct evolution of the states between two arbitrary close time instants is constructed from the filtering error system according to slow‐fast decomposition, sufficient conditions are then proposed based on the consistent projector of the filtering error system and the constructed direct state evolution. Second, a new linear decoupling strategy is presented to deal with the coupled terms under the established stability conditions, which further derives the desired hidden Markov model based filter parameters. A numerical example is given to illustrate the effectiveness of the proposed method.
Prescribed‐time stabilization ofp‐normal nonlinear systems by bounded time‐varying feedback
Authors: Zhang Kang‐Kang , Zhou Bin , Hou Mingzhe , Duan Guang‐Ren 
Published: October 2021

AbstractThis article studies the prescribed‐time stabilization problem ofp‐normal nonlinear systems by bounded time‐varying high‐gain feedback. A time‐varying bounded controller, which can achieve prescribed‐time stabilization, is designed via backstepping. Because of the usage of time‐varying high‐gain functions which grow unbounded as the time tends to the prescribed time, the usual separation technique is invalid. To solve this problem, a novel design scheme is proposed. It is shown that all of the closed‐loop trajectories convergence to the origin in prescribed time. Finally, a numerical example verifies the effectiveness of the proposed method.
Decentralized adaptive tracking control for nonlinear large‐scale systems with unknown control directions
Authors: Wang Ping , Yu Chengpu , Sun Jian 
Published: October 2021

AbstractThis article investigates decentralized adaptive tracking problems for nonlinear large‐scale systems with strong interconnections, unknown control directions and actuator faults. In the presence of measurable system states, a decentralized state feedback control algorithm with a certain inherent fault tolerance capabilities is developed using the dynamic surface control and adaptive techniques. Particularly, a special Nussbaum gain is introduced in the control laws to compensate unknown control directions and unknown bounds of actuator efficiency factor. Using the graph theory and Lyapunov analysis method, it is proved that the designed fault‐tolerant state feedback controller can drive the tracking error for each subsystem to a small neighborhood of the origin while keeping the semiglobal uniform ultimate boundedness for all other closed‐loop signals. When the system states are unmeasurable, an output feedback fault‐tolerant control framework is also formed by introducing a newK‐filters with adjustable parameters and constructing appropriate coordinate transformations. Finally, the effectiveness of the proposed fault‐tolerant control algorithms is verified by simulating two system models.
Colorings, transversals, and local sparsity
Authors: Kang Ross J. , Kelly Tom 
Published: October 2021

AbstractMotivated both by recently introduced forms of list coloring and by earlier work on independent transversals subject to a local sparsity condition, we use the semi‐random method to prove the following result. For any function satisfying as , there is a function satisfying as such that the following holds. For any graph H and any partition of its vertices into parts of size at least such that (a) for each part the average over its vertices of degree to other parts is at most d, and (b) the maximum degree from a vertex to some other part is at most , there is guaranteed to be a transversal of the parts that forms an independent set of H. This is a common strengthening of two results of Loh and Sudakov (2007) and Molloy and Thron (2012), each of which in turn implies an earlier result of Reed and Sudakov (2002).
Achieving ultra‐low friction of a‐C:H film grown on 9Cr18Mo steel for industrial application via programmable high power pulse magnetron sputtering

Published: October 2021

Owing to the high hardness and hydrogen passivation of carbon bonds, hydrogenated diamond‐like carbon (a‐C:H) film has shown promising potential to achieve ultra‐low friction and wear on steel surfaces. Here, a‐C:H film was successfully deposited on 9Cr18Mo steel via programmable high power pulse magnetron sputtering and potential application for industrial was evaluated. The a‐C:H films against different mating materials of GCr15 steel balls, Al2O3, Si3N4, ZrO2, and a‐C:H‐coated GCr15 balls all showed ultra‐low friction under a normal load of 5 N in a dry ambient air environment. Among them, self‐mating tribo‐system a‐C:H films on steel surfaces and a‐C:H‐coated steel balls achieve best friction performance; the principal reason is that both contacting surfaces coated with a‐C:H film have the lower electron affinities compared with other tribo‐systems. However, the differences of coefficient of friction (COF) for uncoated‐GCr15, Al2O3, ZrO2, Si3N4, and a‐C:H(GCr15) balls can be attributed to different sizes of clustering in wear debris. This work provides new insights on synthesis and industry application of the a‐C:H films with ultra‐low friction properties.
Probing Atomic‐Scale Fracture of Grain Boundaries in Low‐symmetry 2D Materials

Published: October 2021

AbstractGrain boundaries (GBs) play a central role in the fracture of polycrystals. However, the complexity of GBs and the difficulty in monitoring the atomic structure evolution during fracture greatly limit the understanding of the GB mechanics. Here, in situ aberration‐corrected scanning transmission electron microscopy and density functional theory calculations are combined to investigate the fracture mechanics in low‐symmetry, polycrystalline, 2D rhenium disulfide (ReS2), unveiling the distinctive crack behaviors at different GBs with atomic resolution. Brittle intergranular fracture prefers to rip through the GBs that are parallel to the Re chains of at least one side of the GBs. In contrast, those GBs, which do not align with Re chains on either side of the GBs, are highly resistant to fracture, impeding or deflecting the crack propagation. These results disclose the GB type‐dependent mechanical failure of anisotropic 2D polycrystals, providing new ideas for material reinforcement and controllable cutting via GB engineering.
Arrested Coalescence of Ionic Liquid Droplets: A Facile Strategy for Spatially Organized Multicompartment Assemblies

Published: October 2021

AbstractMulticompartment assemblies attract much attention for their wide applications. However, the fabrication of multicompartment assemblies usually requires elaborately designed building blocks and careful controlling. The emergence of droplet networks has provided a facile way to construct multiple droplet architectures, which can further be converted to multicompartment assemblies. Herein, the bind motif‐free building blocks are presented, which consist of the hydrophobic Tf2N−‐based ionic liquid (IL) dissolving LiTf2N salt, that can conjugate via arrested coalescence in confined‐space templates to form IL droplet networks. Subsequent ultraviolent polymerization generates robust free‐standing multicompartment assemblies. The conjugation of building blocks relies not on the peripheral bind motif but on the interfacial instability‐induced arrested coalescence, avoiding tedious surface modification and assembly process. By tuning structures of templates and building blocks, multicompartment assemblies with 0D, 1D, 2D, and 3D structures are prepared in a facile and high‐throughput way. Importantly, the bottom‐up construction enables modular control over the compositions and spatial positions of individual building blocks. Combining with the excellent solvency of ILs, this system can serve as a general platform towards versatile multicompartment architectures. As demonstrations, by tailoring the chambers the multicompartment assemblies can spatiotemporally sense and report the chemical cues and perform various modes of motion.
Experimental investigation on reinforced concrete beams subjected to axial compressive and shear forces
Authors: Wahbi Amal , Pham Duc Toan , Hassen Ghazi , Garnier Denis , de Buhan Patrick 
Published: October 2021

AbstractThis paper presents two experimental campaigns carried out on 36 reinforced concrete (RC) beams (with and without shear reinforcement) subjected to a three‐point bending loading with a shear force on the one hand, an axial compressive load and a negative bending moment applied at each end of the beams on the other hand. Such a loading configuration makes it possible to investigate the influence of both axial compression and negative bending moment on the shear capacity of RC beams. For each campaign, three values of axial compressive force were studied, and the test beams were divided into two series with low and high negative bending moment. During the tests, Digital Image Correlation technique was used to capture the cracking evolution of the specimens. Besides, the experimental shear strengths of the beams are confronted to the predictions of Eurocode 2 in order to assess its practical validity. Finally, a semi‐analytical method proposed by Wahbi et al. 2021 (A failure criterion for RC beams subjected to axial and transverse loadings) for evaluating the resistance domain of RC elements subjected to transverse and axial loads, is extended in this paper to take into account the negative bending moment and compared to the experimental results.
Genetic basis for lentil adaptation to summer cropping in northern temperate environments

Published: October 2021

AbstractThe continued success of lentil (Lens culinaris Medik.) genetic improvement relies on the availability of broad genetic diversity, and new alleles need to be identified and incorporated into the cultivated gene pool. Availability of robust and predictive markers greatly enhances the precise transfer of genomic regions from unadapted germplasm. Quantitative trait loci (QTL) for key phenological traits in lentil were located using a recombinant inbreed line (RIL) population derived from a cross between an Ethiopian landrace (ILL 1704) and a northern temperate cultivar (CDC Robin). Field experiments were conducted at Sutherland research farm in Saskatoon and at Rosthern, Saskatchewan, Canada during 2018 and 2019. A linkage map was constructed using 21,634 single nucleotide polymorphisms (SNPs) located on seven linkage groups (LGs), which correspond to the seven haploid chromosomes of lentil. Eight QTL were identified for six phenological traits. Flowering‐related QTL were identified at two regions on LG6. FLOWERING LOCUS T (FT) genes were annotated within the flowering time QTL interval based on the lentil reference genome. Similarly, a major QTL for postflowering developmental processes was located on LG5 with several senescence‐associated genes annotated within the QTL interval. The flowering time QTL was validated in a different genetic background indicating the potential use of the identified markers for marker‐assisted selection to precisely transfer genomic regions from exotic germplasm into elite crop cultivars without disrupting adaptation.

Published: October 2021

AbstractAn 8‐month‐old male castrated domestic shorthair was referred with anorexia, polydipsia, lethargy and diarrhoea, which progressed to marked subcutaneous oedema. The cat had hypoalbuminaemia, hypercholesterolaemia, proteinuria and oedema; clinicopathological findings consistent with severe protein‐losing nephropathy and nephrotic syndrome. Histopathology of ultrasound‐guided percutaneous renal biopsies identified marked podocyte injury with associated focal segmental glomerulosclerosis, a condition rarely reported in cats. The cat fully recovered following medical management with prednisolone and telmisartan, with the resolution of proteinuria.
New fractional model for 2 dimensional half space problem with in the theory of generalized thermoelastic diffusion
Authors: Hussein Eman M. 
Published: October 2021

AbstractIn this manuscript, the generalized thermoelastic diffusion theory is modified by using fractional derivatives. The revised equation is employed to study a two‐dimensional problem of the axisymmetric temperature distribution during a half space with a permeating substance in touch with the bounding plane. The surface of the half space is taken into account to be traction‐free and subject to an axisymmetric temperature distribution. Laplace and Hankel transformation techniques are used. The analytical solution within the transform domain is obtained by an immediate method. By employing a numerical method supported the Fourier expansion technique, the inverse of the double transforms is often obtained. Numerical results for the temperature, displacement, stress, concentration, and chemical potential are administered and represented graphically. The figures show some comparisons to estimate the impact of fractional parameter on all research areas.
