Les niveaux de responsabilité dans l’intervention
Authors: Daigle Marc S.
Published: April 2021

Lorsque survient un suicide en milieu carcéral, le débat sur le partage des responsabilités se situe à au moins quatre niveaux qui ne sont pas toujours très explicites : celui de la société, en général, celui des institutions, celui des intervenants actifs dans ces institutions et, finalement, celui des personnes incarcérées elles-mêmes (qu’elles soient suicidaires ou pairs de suicidaires). Nous sommes tous interpellés à ces différents niveaux et, par-delà la culpabilisation qui pourrait en résulter, notre prise de conscience devrait plutôt nous amener à agir, de façon cohérente et proactive, dans les différentes sphères où nous pouvons avoir une emprise.
Making Performance Real: Six Paths to Training That Matters
Authors: Peterson Brent D. , Song Young Hack , Udell Chuck
Published: April 2021

Training matters not only for business growth but also for talent acquisition and employee retention. Many experts and researchers highlight the importance and benefits of employee learning and development (Salas et al., 2012). The ATD (Association of Talent Development) 2019 State of the Industry and Training Magazine’s 2019 Training Industry Report indicates that billions of dollars and a tremendous amount of time are being spent on training. Many companies are concerned about the value of their current training programs, especially their leadership development programs (Deloitte, 2018; Kirkpatrick & Kirkpatrick, 2018; Beer et al., 2016; Bernal & Schuller, 2016). As we are experiencing a rapid digital transformation and tough economic times, companies are questioning the effectiveness of their leadership development models. This paper, first, aims to examine seven issues in the learning industry that lead to ineffective training from a practitioner’s point of a view. Then it discusses the Peterson, Song, and Udell (PSU) Training Model, an organizational talent development framework consisting of six specific, focused paths. We also focus on our 4E Training Design Model that resolves issues and makes performance real based on evidence from scientific research and insights from our experiences.
Louis Bertrand : autopsie d’une déroute
Authors: Dunwoodie Peter
Published: April 2021

Deux séries de textes du Lorrain Louis Bertrand (1866-1941) apportent un éclairage unique sur l’impact des événements de 1870-1871. Ses « romans africains » (1899-1904) sont le fruit d’une décennie passée en Algérie, entre 1891 et 1900, au cours de laquelle Louis Bertrand joue un rôle majeur dans le lancement d’une littérature algérienne de langue française et dans le processus de légitimation de la colonisation française à travers les notions d’« Afrique latine » et de « peuple néo-français ». Cette perspective non hexagonale, qui voit dans le musulman algérien un ennemi irréductible, vient étayer un rapport ambigu vis-à-vis de l’Allemagne qui est au coeur des oeuvres de la période 1925-1939, dans lesquelles il attire l’attention, en premier lieu, sur le fait que sa génération est « fille de la défaite » de 1870 et que son héros « comme tous ceux de son pays et de sa génération […] avait été élevé dans l’idée de la revanche ». En auscultant une période clé de sa formation, son autobiographie (Une destinée) analyse des tendances intellectuelles et culturelles collectives des années 1870-1914 pour démontrer que le véritable danger vient non pas de ces ennemis héréditaires « du dehors », mais de la France républicaine elle-même, de sa décadence et du manque du « sens de l’ennemi » (titre d’un ouvrage clé, paru en 1917). Nous analysons comment Louis Bertrand, en « romancier et archéologue », voit chez les néo-Français de l’Algérie (perçus comme des Latins et donc des catholiques) « une école d’énergie et quelquefois d’héroïsme, de régénération physique, intellectuelle, nationale et sociale » qui pourrait stopper le déclin d’une France anémiée et défaitiste.
François de Curel ou la « dédramatisation du drame »
Authors: Kaczmarek Tomasz
Published: April 2021

François de Curel est passé dans l’histoire du théâtre français pour un auteur de « pièces à thèse ». Pourtant, ce dramaturge, qui jouissait à son époque d’une renommée incontestable, suscitait des controverses parmi les partisans et les défenseurs de l’art dramatique traditionnel. De fait, en étudiant ses premières oeuvres, L’envers d’une sainte et L’invitée, force nous est de constater qu’il tourne résolument le dos aux principes régulateurs de la fable hérités d’Aristote. Il renonce à l’action basée sur une tension dramatique qui va de l’exposition, en passant par les péripéties – qui tendent inévitablement à la catastrophe –, au dénouement. À l’instar d’Ibsen, il « dédramatise » la forme canonique à travers la « rétrospection », le renversement du sens de l’intrigue et la présence de « personnages passifs » privés de toute volonté d’agir. Curel semble proposer un « drame statique » dans lequel, au lieu de conflits interpersonnels, nous assistons à des affrontements intrasubjectifs dans la psyché des protagonistes. En abandonnant l’action classique, l’écrivain dépouille ses personnages de « caractère » en se concentrant sur l’analyse psychologique de leur âme égarée. C’est ainsi qu’à la place d’un personnage agissant, il met en avant un personnage réflexif ou récitant, qui ressasse son dégoût de la vie.
Don’t fight the tape! Technical Analysis Momentum and Contrarian Signals as Common Cognitive Biases
Authors:   Warsaw University of Life Sciences, Zielonka Piotr , Białaszek Wojciech ,   SWPS University of Social Sciences and Humanities, Biedrzycki Paweł ,   Kozminski Univeristy, Dzik Bartłomiej ,   Kozminski University
Published: April 2021

Purpose: Stock market participants use technical analysis to seek trends in stock price charts despite its doubtful efficiency. We tested whether technical analysis signals represent typical and common cognitive biases associated with the continuation or reversal of the trend. Methodology: We compared investors’ opinions about the predictive power of technical analysis signals grouped into five conditions: real technical analysis signals associated with trend continuation (real momentum signals) or trend reversal (real contrarian signals), fake momentum or fake contrarian signals, and fluctuation signals. Findings: Investors assigned larger predictive power to real and fake signals associated with trend continuation than to signals associated with trend reversal. Fake signals, which represented cognitive biases, elicited similar predictions about trend continuation or reversal to real technical analysis signals. Originality: Market players assess momentum signals to have greater predictive power than contrarian signals and neutral signals to have the least predictive power. These results are independent of whether technical analysis signals were well-known to investors or made up by experimenters. The hardwired propensity of our brains to detect patterns combined with the non-natural environment of the stock market creates the illusion of expertise that is not easy to dispel.
Erasmus staff exchanges: A critical exploration of intentions and effects
Authors:   The Hague University of Applied Sciences, Nixon Paul
Published: April 2021

This article outlines the expected benefits of ERASMUS+ Teaching/Training Exchanges for individuals, the institution as a whole and the degree programmes of The Hague University of Applied Sciences (THUAS), the Netherlands. The method employed was a series of semi-structured interviews, following initial email contact of 32 (approx. 1.5% of staff) who had been on exchange, or were scheduled to be, during the academic year. Interviews were agreed with 7 staff. Leask (2015) identified a lack of research in this area, and it is hoped this research will help to stimulate thinking on this issue. Despite the small sample size, general preliminary conclusions can be drawn and further research is encouraged. The article examines processes and procedures in place for monitoring such exchanges, and it also explores control and monitoring prior to the exchange taking place, as well as post-exchange outcomes and evaluations. It describes the context and theoretical frameworks and discusses the major findings, including accounts of the participants’ experiences and the benefits for them as individuals, their perceptions, their line manager’s responses and institutional policies and processes. The conclusion has recommendations for improvement based upon the participants’ comments. The main message of this article is the need to set goals for the individual and the institution and to evaluate them upon return.
The application of volume texture extraction to three-dimensional seismic data – lithofacies structures exploration within the Miocene deposits of the Carpathian Foredeep
Authors: Łukaszewski Mariusz
Published: April 2021

There are numerous conventional fields of natural gas in the Carpathian Foredeep, and there is also evidence to suggest that unconventional gas accumulations may occur in this region. The different seismic sig-natures of these geological forms, the small scale of amplitude variation, and the large amount of data make the process of geological interpretation extremely time-consuming. Moreover, the dispersed nature of information in a large block of seismic data increasingly requires automatic, self-learning cognitive processes. Recent developments with Machine Learning have added new capabilities to seismic interpretation, especially to multi-attribute seismic analysis. Each case requires a proper selection of attributes. In this paper, the Grey Level Co-occurrence Matrix method is presented and its two texture attributes Energy and Entropy. Haralick’s two texture parameters were applied to an advanced interpretation of the interval of Miocene deposits in order to discover the subtle geological features hidden between the seismic traces. As a result, a submarine-slope channel system was delineated leading to the discovery of unknown earlier relationships between gas boreholes and the geological environment. The Miocene deposits filling the Carpathian Foredeep, due to their lithological and facies diversity, provide excellent conditions for testing and implementing Machine Learning techniques. The presented texture attributes are the desired input components for self-learning systems for seismic facies classification.
Portable XRF spectrometer with helium flow as a tool for lithological interpretation
Authors: Skupio Rafal
Published: April 2021

Portable EDXRF (Energy Dispersive X-Ray Fluorescence) spectrometer with the ability to perform rock tests in a helium atmosphere was applied to prepare unique calibration coefficients and mineralogical models. These data could be used for the chemical profiling, chemostratigraphy, gamma-ray, TOC and lithological interpretation of borehole geological profile. The measurements were conducted on 19 samples of sandstones and compared to the XRF data without helium flow. The acquired dataset was calibrated to the chemical laboratory tests (ICP-MS), gamma-ray spectrometry measurements (RT-50) and combined with the mineralogical data (XRD). The new methodology enables the measurement of sodium and enhances the possibility of detecting magnesium, thorium and uranium, compared to standard handheld XRF spectrometers. The applied method is dedicated to whole cores (without sample preparation) or cuttings which must be cleaned, dried, milled and pressed.
AAV-Txnip prolongs cone survival and vision in mouse models of retinitis pigmentosa

Published: April 2021

Retinitis pigmentosa (RP) is an inherited retinal disease affecting >20 million people worldwide. Loss of daylight vision typically occurs due to the dysfunction/loss of cone photoreceptors, the cell type that initiates our color and high-acuity vision. Currently, there is no effective treatment for RP, other than gene therapy for a limited number of specific disease genes. To develop a disease gene-agnostic therapy, we screened 20 genes for their ability to prolong cone photoreceptor survival in vivo. Here, we report an adeno-associated virus vector expressing Txnip, which prolongs the survival of cone photoreceptors and improves visual acuity in RP mouse models. A Txnip allele, C247S, which blocks the association of Txnip with thioredoxin, provides an even greater benefit. Additionally, the rescue effect of Txnip depends on lactate dehydrogenase b (Ldhb) and correlates with the presence of healthier mitochondria, suggesting that Txnip saves RP cones by enhancing their lactate catabolism.
Associations of topic-specific peer review outcomes and institute and center award rates with funding disparities at the National Institutes of Health
Authors: Lauer Michael S , Doyle Jamie , Wang Joy , Roychowdhury Deepshikha
Published: April 2021

A previous report found an association of topic choice with race-based funding disparities among R01 applications submitted to the National Institutes of Health (‘NIH’) between 2011 and 2015. Applications submitted by African American or Black (‘AAB’) Principal Investigators (‘PIs’) skewed toward a small number of topics that were less likely to be funded (or ‘awarded’). It was suggested that lower award rates may be related to topic-related biases of peer reviewers. However, the report did not account for differential funding ecologies among NIH Institutes and Centers (‘ICs’). In a re-analysis, we find that 10% of 148 topics account for 50% of applications submitted by AAB PIs. These applications on ‘AAB Preferred’ topics were funded at lower rates, but peer review outcomes were similar. The lower rate of funding for these topics was primarily due to their assignment to ICs with lower award rates, not to peer-reviewer preferences.
Application of improved fuzzy best worst analytic hierarchy process on renewable energy
Authors: Majumder Priyanka , Balas Valentina Emilia , Paul Arnab , Baidya Dayarnab
Published: April 2021

In this work, a novel fuzzy decision making technique namely trapezoidal fuzzy Best-Worst method (fuzzy BWM) is developed which is based on Best-Worst method (BWM) and Trapezoidal fuzzy number. The real motive behind our work is to take a broad view of the existing fuzzy BWM based on triangular fuzzy number by trapezoidal fuzzy number. Also, we have presented a new hybrid MCDM technique called as Trapezoidal fuzzy Best Worst Analytic Hierarchy based on proposed trapezoidal fuzzy BWM and existing trapezoidal fuzzy Analytic Hierarchy Process (AHP). BWM approach is employed in evaluating the PV of considering criteria and trapezoidal fuzzy AHP is used to assess the local priority vale (PV) of considering alternatives (or indicators) of a decision problem. Moreover it used to identify the most significant alternative which is responsible for performance efficiency of a hydro power plant under climatic scenario. From the result, it is undoubtedly found that hydraulic had is most responsible indicator. Further, the CR (consistency ratio) value which is determined by our proposed trapezoidal fuzzy BWM is less than that of existing BWM and fuzzy BWM techniques. Finally, we have validated our result by comparative study, scenario analysis and sensitivity analysis.

Authors: Mehta Pooja , Pandya Sharnil , Kotecha Ketan
Published: April 2021

Information gathering has become an integral part of assessing people’s behaviors and actions. The Internet is used as an online learning site for sharing and exchanging ideas. People can actively give their reviews and recommendations for variety of products and services using popular social sites and personal blogs. Social networking sites, including Twitter, Facebook, and Google+, are examples of the sites used to share opinion. The stock market (SM) is an essential area of the economy and plays a significant role in trade and industry development. Predicting SM movements is a well-known and area of interest to researchers. Social networking perfectly reflects the public’s views of current affairs. Financial news stories are thought to have an impact on the return of stock trend prices and many data mining techniques are used address fluctuations in the SM. Machine learning can provide a more accurate and robust approach to handle SM-related predictions. We sought to identify how movements in a company’s stock prices correlate with the expressed opinions (sentiments) of the public about that company. We designed and implemented a stock price prediction accuracy tool considering public sentiment apart from other parameters. The proposed algorithm considers public sentiment, opinions, news and historical stock prices to forecast future stock prices. Our experiments were performed using machine-learning and deep-learning methods including Support Vector Machine, MNB classifier, linear regression, Naïve Bayes and Long Short-Term Memory. Our results validate the success of the proposed methodology.

Published: April 2021

Vehicular edge computing (VEC) is a potential field that distributes computational tasks between VEC servers and local vehicular terminals, hence improve vehicular services. At present, vehicles’ intelligence and capabilities are rapidly improving, which will likely support many new and exciting applications. The network resources are well-utilized by exploiting neighboring vehicles’ available resources while mitigating the VEC server’s heavy burden. However, due to the vehicles’ mobility, network topology, and the available computing resources change rapidly, which are difficult to predict. To tackle this problem, we investigate the task offloading schemes by utilizing vehicle to vehicle and vehicle to infrastructure communication modes and exploiting the vehicle’s under-utilized computation and communication resources, and taking the cost and time consumption into account. We present a promising relay task-offloading scheme in vehicular edge computing (RVEC). According to this scheme, the tasks are offloaded in a vehicle to vehicle relay for computation while being transmitted to VEC servers. Numerical results illustrate that the RVEC scheme substantially enhances the network’s overall offloading cost.

Published: April 2021

AP2/ERF transcription factors (TFs) play indispensable roles in plant growth, development, and especially in various abiotic stresses responses. The AP2/ERF TF family has been discovered and classified in more than 50 species. However, little is known about the AP2/ERF gene family of Chinese willow (Salix matsudana), which is a tetraploid ornamental tree species that is widely planted and is also considered as a species that can improve the soil salinity of coastal beaches. In this study, 364 AP2/ERF genes of Salix matsudana (SmAP2/ERF) were identified depending on the recently produced whole genome sequencing data of Salix matsudana. These genes were renamed according to the chromosomal location of the SmAP2/ERF genes. The SmAP2/ERF genes included three major subfamilies: AP2 (55 members), ERF (301 members), and RAV (six members) and two Soloist genes. Genes’ structure and conserved motifs were analyzed in SmAP2/ERF family members, and introns were not found in most genes of the ERF subfamily, some unique motifs were found to be important for the function of SmAP2/ERF genes. Syntenic relationships between the SmAP2/ERF genes and AP2/ERF genes from Populus trichocarpa and Salix purpurea showed that Salix matsudana is genetically more closely related to Populus trichocarpa than to Salix purpurea. Evolution analysis on paralog gene pairs suggested that progenitor of S. matsudana originated from hybridization between two different diploid salix germplasms and underwent genome duplication not more than 10 Mya. RNA sequencing results demonstrated the differential expression patterns of some SmAP2/ERF genes under salt stress and this information can help reveal the mechanism of salt tolerance regulation in Salix matsudana.
Cisplatin-resistant HepG2 cell-derived exosomes transfer cisplatin resistance to cisplatin-sensitive cells in HCC
Authors: Tang Zuxiong , He Jun , Zou Jiayue , Yu Shufei , Sun Xiaoming , Qin Lei
Published: April 2021

Backgrounds

Cancer cell resistance to chemotherapy drugs such as Gemcitabine, Oxaliplatin, Cisplatin, Doxorubicin, and 5-fluorouracil account for the main reason of chemotherapy failure for HCC patients, especially for those with advanced HCC or metastasis patients. This emerging resistance limits the effectiveness and clinical application of these chemotherapy drugs. Previous studies reported that drug-resistant tumor cell-derived exosomes could transfer their resistance property to tumor sensitive cells in some cancer, including lung and gastric cancer. This study sought to explore whether HepG2/DDP cell-derived exosomes transmit cisplatin (DDP) resistance to HepG2 and other HCC sensitive cells, and provide considerable guidance for HCC nursing with Cisplatin DDP clinically.

Methods

The HepG2 DDP-resistant cell line (HepG2/DDP) was established, and the exosomes from both HepG2/DDP and HepG2 cells were isolated and named ES-2, ES-1, respectively. HepG2 or SMMC-7721 or Huh7 cells were treated with DDP or DDP + ES-2, and HepG2/DDP cells were treated with ES-1. Then, the activation of drug resistance via HepG2/DDP exosomes transfer to HepG2, SMMC-7721 and Huh7 cells were assessed by cell viability assay and ROS formation. Moreover, the relative expression of P-glycoprotein (P-gp) was measured by western blot analysis.

Results

HepG2/DDP cell-derived exosomes were successfully isolated from cisplatin-resistant HepG2 cells, and named ES-2. Cell viability of HepG2 or SMMC-7721 or Huh7 cells treated with DDP + ES-2 was enhanced compared with that of DDP treatment group. Also, the concentration of ROS generated in cells under DDP or DDP + ES-2 treatment was strongly increased compared with that of control, although the concentration of ROS was clearly smaller in DDP + ES-2 treatment group compared with DDP treatment. At the same time, the expression of P-gp was upregulated on the ES-2 surface.

Conclusion

The results mentioned above clarified that HepG2/DDP cell-derived exosomes conferred cisplatin resistance to HepG2 and other HCC cell lines, and provided a new significance for improving the effectiveness of DDP in treating HCC.

Background

The complications from coronavirus disease 2019 (COVID-19) have been the subject of study in diverse scientific reports. However, many aspects that influence the prognosis of the disease are still unknown, such as frailty, which inherently reduces resistance to disease and makes people more vulnerable. This study aimed to explore the complications of COVID-19 in patients admitted to a third-level hospital and to evaluate the relationship between these complications and frailty.

Methods

An observational, descriptive, prospective study was performed in 2020. A sample of 254 patients from a database of 3,112 patients admitted to a high-level hospital in Madrid, Spain was analyzed. To assess frailty (independent variable) the Clinical Frailty Scale (CFS) was used. The outcome variables were sociodemographic and clinical, which included complications, length of stay, intensive care unit (ICU) admission and prognosis.

Results

A total of 13.39% of the patients were pre-frail and 17.32% were frail. Frail individuals had a shorter hospital stay, less ICU admission, higher mortality and delirium, with statistical significance.

Conclusion

Frailty assessment is a crucial approach in patients with COVID-19, given a higher mortality rate has been demonstrated amongst frail patients. The CFS could be a predictor of mortality in COVID-19.

Published: April 2021

Spontaneous rupture of the spleen is a rare disorder and has been reported to occur due to Haematological, neoplastic and infectious diseases involving the Spleen. We present a case of 25 years young male who presented with epigastric pain and fever since 4 days. The contrast enhanced computed tomography scan showed complete distortion of splenic architecture with perisplenic mixed density collection suggested splenic rupture. Pancreas was bulky in the tail region with adjacent fluid density collection. The peripancreatic fluid in the tail region eroded the splenic capsule and penetrated into splenic parenchyma causing spontaneous rupture of the spleen. It also eroded the vessel and caused haematoma. Splenic artery embolisation was done and later managed conservatively.

Published: April 2021

Introduction: Breast cancer is the most common cause of cancer related mortality in Indian women. Aim: To evaluate the imaging characters of Triple Negative Breast Cancer (TNBC) on Mammography and Ultrasonography (USG), with the major goal of identifying imaging predictors of TNBC. Materials and Methods: The present retrospective case-control study was conducted at AIIMS, Rishikesh, Uttarakhand, India, over a period of one year from September 2018 to August 2019. The imaging findings of 50 cases of histopathologically proven TNBC were retrospectively evaluated by two breast radiologists. This was compared with 50 age matched blindly chosen cases of non-TNBC. The statistically significant imaging characters of TNBC were identified by Chi-square test. The imaging predictors of TNBC were identified by regression analysis. Results: The most common mammographic presentation of TNBC was mass without calcification (64%) with round/oval shape (54%) and lobulated margins (38%). The most common ultrasonographic presentation was hypoechoic mass (76%) with round/oval shape (52%) and lobulated margins (44%) with Posterior Acoustic Enhancement (PAE) (54%). PAE (p<0.0001: Area Under Curve (AUC): 0.6200) on USG was the single strongest imaging predictor of TNBC, followed by lobulated margins on mammography (p<0.001: AUC: 0.6300). On multivariate analysis, a lobulated, hypoechoic mass with PAE was found to be the most statistically confident predictor of TNBC on imaging. Conclusion: TNBC has specific imaging features on both mammography and USG which may be used as utility tools in early diagnosis. A round, lobulated mass on both modalities with hypoechogenicity and PAE on USG are definite red flags for TNBC on imaging.

Published: April 2021

Widely reports have evaluated the use of biochar (BC) composites to layered double hydroxide (LDH) to adsorb dyes from wastewater. However, its applicability for adsorbing a mixture of cationic dyes such as Malachite green (MG), Rodhamine-B (Rh-B), and Methylene blue (MB), which causes carcinogenic and mutagenic effects on aquatic life, has not been studied. In this work, we compared the performance of CaAl-LDH/BC adsorbent with or without the addition of BC in the adsorption of cationic dyes. The adsorption study was prepared in a batch system using various temperatures, concentrations, and also contact time. The results of the characterization of Ca/Al-Biochar composite showed the unique diffraction of XRD pattern, and also showed two characteristics of starting materials. Surface area analysis by BET method showed Ca/Al-Biochar composite has a higher surface area than starting material. The results of the adsorption study of MG showed that Ca/Al-Biochar follows the pseudo-second-order kinetic model. The adsorption capacity of MG on Ca/Al-Biochar was up to 71.429 mg/g and shows selectivity toward MG in an aqueous solution. Copyright © 2021 by Authors, Published by BCREC Group.

Hydrophobic recovery of femtosecond laser processed silicone rubber insulator surfaces
Authors: Chen Lie , Nie Qilu , Hu Tao , Bennett Peter , Zheng Zhong , Yang Qibiao , Liu Dun
Published: April 2021

This article demonstrates the loss and recovery in hydrophobicity of silicone rubber insulator surface processed by a femtosecond laser. The two stages of the wettability conversion were investigated. First, a rough micro/nano structure was formed on the original hydrophobic sample surface processed by the femtosecond laser, and the water contact angle on the surface was reduced from ~ 110° to a minimum of ~ 35°. This hydrophilicity loss was due to the increase in the hydrophilic OH groups and the reduction of the hydrophobic CH3 groups on the surfaces. Second, the roughened samples were stored in a natural ambient environment. Over a certain storage time, the surface hydrophobicity recovered gradually and evolved into a superhydrophobic state. It was found that the migration of low molecular weight cycle and/or linear siloxane oligomers resulted in the recovery of the hydrophobicity property. Coupled with the increase of surface roughness caused by laser irradiation, the further evolution of the hydrophobicity was promoted. Moreover, the higher temperature accelerates the recovery of the surface hydrophobicity. The research on the conversion mechanism of the wettability on the silicone rubber insulator surface processed by femtosecond laser is of great significance for improving its reliability in practical applications.

Published: April 2021

Polyaniline (PANI) is a potential candidate for n‐type thermoelectric (TE) materials owing to its intrinsic electrical conductivity, low thermal conductivity, and facile synthesis techniques. However, its low Seebeck coefficient and power factor have limited its widespread usage. In this study, nitrogen‐doped, and sulfur‐nitrogen co‐doped reduced graphene oxide (rGO) were used for tuning the TE properties of PANI. Doped rGO and PANI/doped‐rGO nanocomposites were prepared via hydrothermal technique and chemical oxidative polymerization respectively and thereafter characterized. The TE properties of the nanocomposites were also studied and an optimized Seebeck coefficient, power factor and zT value of −1.75 mV K−1, 95 μW m−1 K−2 and 0.06, respectively were reported for the PANI nanocomposite containing 1 wt% sulfur‐nitrogen co‐doped rGO. These results suggest that PANI/heteroatom‐doped rGO can serve as promising candidates for n‐type based TE applications.
Effect of conductive carbon black on electrical conductivity and performance of tire tread compounds filled with carbon black/silica hybrid filler
Authors: Thaptong Puchong , Jittham Pairote , Sae‐oui Pongdhorn
Published: April 2021

For green tires, carbon black (CB) is partially replaced by silica (SiO2) in the tread formula in order to improve wet grip (WG) and fuel saving efficiency (FSE). However, such replacement inversely affects electrical conductivity of a tire resulting a greater potential for static shock or electrostatic ignition. This work aimed to improve electrical conductivity of the tread compound by partially replacing either CB or SiO2 by 0–12 phr of conductive carbon black (CCB) (with replacing ratio of 2:1) and investigating the effect of such replacement on the tire performance. Although the partial replacement of CB or SiO2 by CCB increased the magnitude of transient filler network resulting in the negative effects on heat build‐up, WG and FSE of the tread vulcanizates, it significantly improved electrical conductivity. Surface resistivity decreased sharply when CB or SiO2 was replaced by 3 phr of CCB, revealing the point of percolation threshold. In addition, the partial replacement of CB or SiO2 by CCB did not cause significantly change of both hardness and tensile properties. At any given CCB loading, the SiO2 replacement provided greater surface conductivity and higher abrasion resistance with lower WG and FSE than the CB replacement.

People with autism spectrum disorder (ASD) exhibit a variety of medical morbidities at significantly higher rates than the general population. Using an established monkey model of naturally occurring low sociality, we investigated whether low‐social monkeys show an increased burden of medical morbidities compared to their high‐social counterparts. We systematically reviewed the medical records of N = 152 (n = 73 low‐social; n = 79 high‐social) rhesus macaques (Macaca mulatta) to assess the number of traumatic injury, gastrointestinal, and inflammatory events, as well as the presence of rare medical conditions. Subjects' nonsocial scores, determined by the frequency they were observed in a nonsocial state (i.e., alone), and macaque Social Responsiveness Scale‐Revised (mSRS‐R) scores were also used to test whether individual differences in social functioning were related to medical morbidity burden. Medical morbidity type significantly differed by group, such that low‐social monkeys incurred higher rates of traumatic injury compared to high‐social monkeys. Nonsocial scores and mSRS‐R scores also significantly and positively predicted traumatic injury rates, indicating that monkeys with the greatest social impairment were most impacted on this health measure. These findings from low‐social monkeys are consistent with well‐documented evidence that people with ASD incur a greater number of traumatic injuries and receive more peer bullying than their neurotypical peers, and add to growing evidence for the face validity of this primate model.

Lay Summary

People with autism exhibit multiple medical problems at higher rates than the general population. We conducted a comprehensive medical record review of monkeys that naturally exhibit differences in sociality and found that low‐social monkeys are more susceptible to traumatic injuries than high‐social monkeys. These results are consistent with reports that people with autism also incur greater traumatic injury and peer bullying and add to growing evidence for the validity of this monkey model.

The effects of exposure to intermediate‐frequency electromagnetic fields (IF‐EMFs) during pregnancy on birth outcomes are uncertain. We investigated the association between the use of induction heating (IH) cookers, which are major sources of IF‐EMFs, during pregnancy and preterm birth (PTB), low birth weight (LBW), small‐for‐gestational‐age (SGA), and birth weight, using data from a prebirth cohort study in Japan. Study participants were 1,565 mothers with singleton pregnancies and the babies born from these pregnancies. We collected the data presented here using self‐administered questionnaires. An adjustment was made for maternal age, region of residence, number of children, family structure, maternal education, maternal employment, maternal alcohol intake, smoking during pregnancy, maternal body mass index, baby's sex, and gestational age at birth. IH cooker use during pregnancy was independently associated with a reduced risk of PTB: the adjusted odds ratio was 0.28 (95% confidence interval: 0.07–0.78). IH cooker use during pregnancy was not associated with LBW, SGA, or birth weight. This is the first study to show that IH cooker use during pregnancy is independently inversely associated with PTB.

COVID‐19 leads to severe respiratory problems, but also to long‐COVID syndrome associated primarily with cognitive dysfunction and fatigue. Long‐COVID syndrome symptoms, especially brain fog, are similar to those experienced by patients undertaking or following chemotherapy for cancer (chemofog or chemobrain), as well in patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) or mast cell activation syndrome (MCAS). The pathogenesis of brain fog in these illnesses is presently unknown but may involve neuroinflammation via mast cells stimulated by pathogenic and stress stimuli to release mediators that activate microglia and lead to inflammation in the hypothalamus. These processes could be mitigated by phytosomal formulation (in olive pomace oil) of the natural flavonoid luteolin.

Published: April 2021

This study aims to determine the impact of environmental sustainability (ES) on firm financial performance (FFP). The study also examines the mediation of ES in the relationship between integrated management strategies (IMS) and FFP. By employing the content analysis technique for global reporting initiative (GRI) framework, the study collected desired data from the sustainability, corporate social responsibility, and annual reports of the sample firms (1,275 firm‐year observations) listed on the Pakistan stock exchange (PSX) from 2012 to 2016. The study employed at‐test, ordinary least square, and generalized least square estimator with the fixed effect and random effect for estimating the hypothesized relationships. The results revealed that the ES and IMS have a significant positive impact on the FFP (ROA & Tobin's Q). Also, it is observed that ES mediates the relationship between IMS and Tobin's Q. Furthermore, it also noted that the results are more striking after addressing endogeneity. Besides using the unique ES index, the study also contributes to the literature and practice by updating the developing countries' key stakeholders, especially Pakistan.

Risk management in an organization represents a decisive function in seizing opportunities and managing the risks that can affect a business's reputation, prosperity, growth, value creation, stakeholder engagement, long‐term survival, and a firm's contribution to sustainable development. For this paper, we conduct a systematic literature review of 148 indexed studies and uses the “Six Ws” (what, who, why, where, when, and how) approach to understand the linkages between sustainability and risk management. This study's findings reveal that the management of environmental, social, and governance (ESG) concerns plays a mitigation's function on business risks.
Does a sense of calling facilitate sustainability? Research on the influence of calling on employee green behavior
Authors: Zhang Zhe , Zhang Yun , Jia Ming
Published: April 2021

Organizations recently attach growing importance to sustainable development and green human resource management (GHRM), raising research interest in predicting employee green behavior (EGB). However, the potential linkage between a sense of calling and EGB is neglected. This research fills the void by examining whether, how, and when calling predicts EGB. Drawing upon self‐determination theory, we argue that by satisfying three basic psychological needs (i.e., autonomy, competence, and relatedness), a sense of calling enhances employees' prosocial motivation, which in turn promotes EGB. We further propose that calling predicts EGB more effectively for less conscientious employees. We conducted two field surveys to test the hypotheses. Both Study 1 (N = 280) and Study 2 (N = 295) confirm that calling positively affects EGB through partial mediation of prosocial motivation and that conscientiousness negatively moderates the relationship between calling and prosocial motivation as well as the indirect effect. Theoretical contributions and practical implications are discussed.

Policy maintenance at William & Mary is a rigorous, collaborative process
Authors: Rahn Josh
Published: April 2021

In modern law enforcement, the policy manual is not a static collection of fixed rules and requirements. Instead, it's seen as a living document that evolves and changes over time. As progress reveals new and better ways of doing things, the policy manual is constantly reconsidered and updated. The bulk of this work is undertaken by accrediting bodies and professional associations, but the “end users” of the policy manual also make important contributions. The goal is, as always, continuous improvement.
Nothing is consistent — except change

Published: April 2021

For more than a year, leaders of college and university public safety agencies have grappled with the same extraordinary conditions their institutions were forced to adjust to due to the pandemic. Challenges to very familiar workloads, trends, and events have given way to radically different service demands, processes, and duties that had long been well outside of protecting and serving the students, faculty, staff, and visitors of campus.

Published: April 2021

Gastric cancer (GC) is a kind of malignancy originating from the epithelium of gastric mucosa. Long noncoding RNAs (lncRNAs) are tightly related to the GC progression. Herein, our research was meant to investigate a novel lncRNA thymidylate synthetase opposite strand (TYMSOS) in GC. Quantitative real‐time polymerase chain reaction was used to analyze TYMSOS expression in GC cells. 5‐Ethynyl‐2ʹ‐deoxyuridine, flow cytometry analysis, and transwell assay detected the influence of TYMSOS on GC cell proliferation, apoptosis, migration, and invasion. Subcellular fractionation and fluorescent in situ hybridization assays determined the cellular localization of TYMSOS in GC cells. Bioinformatics programs, RNA‐binding protein immunoprecipitation, RNA pull‐down, and luciferase reporter assays measured the molecular interplays of TYMSOS in GC cells. In brief, TYMSOS was highly expressed in GC cells, and TYMSOS silence inhibited GC cell proliferation, migration, and invasion while elevating cell apoptosis. Functionally, TYMSOS functioned as a competing endogenous RNA to posttranscriptionally modulate GC progression. TYMSOS interacted with miR‐4739 to regulate its target gene zinc finger protein 703. Collectively, our study proved the tumor‐promoting role of TYMSOS in GC cells, which might offer the utility value for GC treatment.

Objectives

Report MANTA‐associated vascular complications after implementation of key insights on failure mechanisms.

Background

The MANTA vascular closure device is utilized to close large‐bore arterial access sites. We have previously identified and published the mechanisms and predictors of MANTA‐associated vascular complications. We identified three distinct mechanisms leading to MANTA‐associated vascular complications, predictors were a common femoral artery (CFA) diameter <6 mm and clinically established peripheral artery disease (PAD).

Methods

We compared 100 consecutive patients of the initial cohort (first n = 100) with consecutive patients in which the key insights acquired in the initial cohort were implemented (second n = 100).

Results

The initial cohort (n = 100 patients) had a MANTA‐related vascular complication rate of 11% (7% major and 4% minor), and 14% MANTA‐related bleeding complications. In a subsequent cohort of n = 100 patients, we applied the abovementioned findings: we did not use the MANTA device if the CFA was <6 mm and in patients with PAD. In addition, femoral puncture was ultrasound guided. This strategy led to a decline in MANTA‐related vascular complication rates: 2% (1% major and 1% minor) p = .03, as well as a reduction in MANTA‐related bleeding complications to 5% p = .01. To the best of our knowledge, this is the lowest rate of MANTA‐related vascular complication reported thus far.

Conclusions

Our strategy achieves low MANTA‐related vascular and bleeding complication rates. Careful and critical examination of complications can lead to rapid identification of complication mechanism and its predictors. In turn, rapid implementation of these insights can lead to a decline in complication rates.
