The importance of developing teachers as researchers in the new general education curriculum of Vietnam
Authors: Mai Dung T.T. , Brundrett Mark
Published: April 2022

This paper focuses on the movement known as ‘teachers as researchers’, which has become an international phenomenon, and posits that it may be compatible with the policy of the ‘New General Education Curriculum’ of Vietnam. In order to examine teachers’ perceptions of their ability to undertake such research the methodology employed was qualitative in nature and consisted of two phases including a survey questionnaire with open ended questions administered to respondents in 100 high schools and secondary schools in 35 locations in cities and provinces in Vietnam, followed by in-depth interviews with four practitioners. It analyses the context, examines the challenges, and recommends strategies in order to develop teachers as researchers in the Vietnamese context. The main findings include that teachers currently lack interest in carrying out research because initial teacher training does not equip them sufficiently, they thus do not have confidence that they possess the relevant skills, and they perceive that there are limitations in support and leadership in schools, especially in relation to incentives to carry out research. The paper recommends that policy makers and school leaders take the necessary measures as soon as possible in order to encourage teachers to undertake research on practice since this would enhance the quality of teaching and students’ learning outcomes and contribute to the effective implementation of the new general education curriculum.

Published: April 2022

Introduction: Opioid stewardship efforts can promote safe and effective use of opioids to optimize pain control and minimize unintended consequences. The purpose of this study is to assess the difference in post-operative opioid discharge prescribing in patients undergoing coronary artery bypass graft (CABG) surgery following implementation of a tripartite opioid stewardship intervention. Methods: This was a single-center, quality improvement study at a large, quaternary academic medical center. Adult patients undergoing CABG from July 2019 to June 2020 (pre-intervention) and November 2020 to February 2021 (post-intervention) were included. The intervention included adopting hospital-wide post-surgical opioid discharge prescribing guidelines, discharge prescriber education, and electronic medical record changes. The primary outcome was the proportion of patients receiving an opioid prescription at discharge. Secondary outcomes included total morphine milligram equivalents (MME) prescribed and non-opioid analgesics prescribed at discharge. Results: A total of 200 patients were included in the study; 100 pre- and 100 post-intervention. There was no difference in opioid discharge prescribing at discharge (74% pre-intervention vs. 72% post-intervention; P = .87). There was no difference in MMEs prescribed at discharge (145.6 ± 57 pre- vs. 162.2 ± 95 post-; P = .202). No difference was seen in non-opioid analgesic prescriptions prescribed at discharge (35% pre- vs. 40% post-; P = .56). Conclusion: A multipronged opioid stewardship intervention did not lead to a reduction in opioid prescribing at discharge. Post-intervention, there was a non-statistically significant increase in the proportion of patients who received non-opioid analgesics discharge. Future studies should assess the effect of different stewardship interventions on prescribing and patient outcomes.
Stress Exposure and Physical Health among Older African American and Caribbean Black Women
Authors: Erving Christy L.
Published: April 2022

Objectives: This study assessed whether multiple stress exposures and stress accumulation explained differences in physical health among Afro-Caribbean and African American women in older adulthood. Whether specific stressors uniquely influenced the health of African American and Afro-Caribbean women was also examined. Methods: Data were drawn from the National Survey of American Life (NSAL) ( N=867; 50 years and older). Physical health was assessed by multiple chronic conditions, functional limitations, and self-rated health. Weighted binary logistic regression and ordered logistic regression analyses were conducted. Results: Compared to Afro-Caribbean women, African American women had worse physical health and greater stress exposure. Nonetheless, stress exposure did not explain ethnic differences in physical health. The association between specific measures of stress and physical health was dependent on the stressor and physical health measure. Discussion: Findings emphasize the importance of ethnic variation in health and stress exposure among older US Black women. Study implications are discussed.
Cystic Odontogenic Tumor with Features of Calcifying Odontogenic Cyst in 3 Cats and a Dog
Authors: Babbitt Samuel G. , Bell Cynthia M. , Raleigh Matthew , Haggerty Kevin , Feigin Kristina
Published: April 2022

This case series describes the clinical appearance, radiographic appearance and histopathologic features of 4 patients (3 cats and 1 dog) with unique cystic oral lesions that are consistent with a diagnosis of calcifying odontogenic cyst (COC). COC is a rare odontogenic lesion in humans that has not been previously reported in companion animals. Historically, COC in humans has been classified as a benign cystic neoplasm and as a non-neoplastic odontogenic cyst. Current classification favors the latter. The cases in this series also have ambiguous features regarding classification of the lesion as an odontogenic cyst versus benign neoplasia.
Electoral accountability and political competence
Authors: Gailmard Lindsey
Published: April 2022

Much research contends that candidate competence brings technical or political skill, such that selecting against such attributes seems irrational. However, if special interest coalitions are sufficiently strong, a majority may expect that political expertise will be used to select policies that generate rents for narrow constituencies at the expense of its own welfare. I develop a model in which a majority prefers to elect the less competent politician in order to undermine the incumbent’s ability to pursue the special interest agenda and derive the implications for accountability in this setting. The results demonstrate that the majority’s attempts to reassert control over policy through its retention decisions impede social welfare maximizing reform and distort aggregate welfare by either encouraging ([Formula: see text]) inefficient policy selection or ([Formula: see text]) inefficient candidate selection. Even if politicians choose policies that maximize social welfare doing so may only worsen aggregate welfare by providing voters with more information about candidate competence, which enables the majority to better select inept politicians.

Authors: Thakur Ankit , Sharma Varun , Bhadauria Shailendra Singh
Published: April 2022

In the present study, the effect of tool tilt angle was investigated to appraise the metallurgical and mechanical behavior of double-sided friction stir welded joints of AA-6061 T6 alloy of 6 mm thick plates, using scrolled shoulder and frustum tool pin geometry. Two friction stir welded joints, with 0° (Joint J1) and 2° (Joint J2) tool tilt angles were fabricated using a fixed travel speed of 50 mm/min and tool rotational speed of 800 rpm. The metallurgical studies carried out by the electron backscattered diffraction showed that the incorporation of tool tilt angle resulted in the refinement of grains within the stir zone to a larger extent. The transverse tensile test results revealed that the joint efficiency of the J2 welded joint improved by 12% as compared to the J1 joint. The layered tensile specimens extracted from the different regions (first pass, second pass, and overlap region) of the stir zone of both the welded joints showed an appreciable variation in mechanical and metallurgical properties. The V-notch Charpy impact toughness test for J2 joint showed 16% higher toughness, with the presence of a 55% shear area fraction in the fractured impact specimens, as compared to the 30% for the J1 joint.

Authors: Wang Zhiwei , Dong Chengliang , Zhang Zhenmeng , Tian Qunhong , Sun Aiqin , Yuan Liang , Zhang Lijun
Published: April 2022

At present, single-fin propulsion modes, such as pectoral fins and caudal fins, cannot ensure the mobility and forward speed of bionic robotic fish, whereas a multi-fin and flexible body can better ensure a high propulsion efficiency – particularly with low-speed mobility and high-speed stability. Therefore, the cooperative propulsion mode of the pectoral fin and caudal fin has become a research hotspot in recent years. This paper systematically introduces various actuators of robotic fish, including traditional actuators and functional materials. The functional materials include shape-memory alloy wires, ionic polymer–metal composites and piezoelectric ceramics, and their performance characteristics and limitations are discussed. Functional materials can reduce the volume and weight of a robot and reduce noise. Underwater robots have the advantages of flexibility and the ability to perform complex motions. Therefore, flexible robotic fish that combine the flexible behaviour of real fish with robot technology are gradually emerging. Finally, future research directions for bionic robotic fish are presented.

Published: April 2022

Longitudinal damping derivatives, [Formula: see text], of an aerial vehicle is important from an aerodynamic stability point of view. Experimental calculation of longitudinal damping derivatives using wind tunnel is not a cost-effective method; therefore, researchers have developed numerical solutions as an alternative. In this research, the longitudinal damping derivatives of a flying wing micro aerial vehicle (FWMAV) were calculated using numerical simulations by adopting pull-up maneuver and forced harmonic motion in pitch axis. Pull-up maneuver with four steady rotational rates was simulated to obtain pitch rate derivative, C mq. Combined derivative, [Formula: see text], was obtained by simulating forced harmonic motion of FWMAV around a mean angle of attack of 0° with amplitude of oscillation of ± 3° using four reduced frequencies (0.02, 0.03, 0.04, and 0.05). Unstructured surface and volume mesh was used in a spherical domain engulfed inside a large cuboid domain for moving reference frame strategy. Reynolds number taking mean aerodynamic chord as a reference length was 2.33 × 105. Spalart–Allmaras turbulence model was used. Pitch rate derivative, combined derivative, and acceleration derivative were found as − 0.03/rad, − 7.39/rad, and − 7.36/rad, respectively, by the use of a phase method at a reduced frequency of 0.03. During flight dynamic analysis, it was found that [Formula: see text] has a significant contribution on damping in short period mode with no effect on Phugoid mode. The research concluded that for tailless configurations, acceleration derivative [Formula: see text] can exist and can provide necessary damping in the longitudinal flight mode.

Published: April 2022

Lug structure is an important connection structure in aviation aircraft. However, fatigue cracks are easily generated during the service of the aircraft. Therefore, this study aims to explore the influence of different structural parameters on the fatigue life of the 7075-T651 aluminum alloy lug, using experimental and numerical methods to determine the effects of these structural parameters. Scanning electron microscopy was employed for fracture analysis, and three-dimensional finite element models were used to solve the holes edge stress distributions under peak load and stress concentration factor. The results indicate that the fatigue life of the lug increases with the increase in the extrusion projection area and the included angle of the outer edge, and the impact of the extrusion projection area on the fatigue life of the lug is greater than the angle of the outer edge, and the fatigue life of the lug does not change with the change of the chamfer at the bottom. The peak stress at the root of the lug hole becomes the main factor affecting the fatigue life of the lug, and the crack always expands along the net cross-section of each parameter lug.
Is Felix Salten the author of the Mutzenbacher novel (1906)? Yes and no
Authors: Rebora Simone , Salgaro Massimo
Published: April 2022

Josefine Mutzenbacher oder die Geschichte einer Wienerischen Dirne von ihr selbst erzählt, published in Vienna in 1906, represents one of the most fascinating cases of attribution of authorship in German literature. Although Josefine Mutzenbacher is usually attributed to Felix Salten, the author of the world-famous Bambi (1923), the novel’s authorship has never been confirmed, and many other candidates have been named as potential authors. Among them is Arthur Schnitzler, who published Reigen, a cycle of amorous adventures in Viennese society, in 1903. Some scholars, instead, have attributed the novel to such lesser-known writers as Ernst Klein and Willi Handl. The controversy surrounding the authorship of Josefine Mutzenbacher was the starting point for our stylometric analyses, and our results help to answer some unresolved questions in a debate that has lasted for more than 100 years. The analyses were performed using the R package Stylo, which enables an efficient application of Burrows’ Delta and its variants. Focusing on both the entire text and on the final pages, two different types of analysis were carried out: one combines 1200 different stylometric methods to compare the candidate authors Salten, Schnitzler, Bahr, Altenberg, Hofmannsthal, Klein and Handl; the other verifies the attribution using the ‘impostors’ method. The results show that the most probable author is Felix Salten, while none of the candidates could be identified as the author of the final pages, confirming the hypothesis that the text was left unfinished by Salten and completed by an as-yet-unidentified ghost-writer.

Authors: Stoffel Sandro T , McGregor Lesley , Hirst Yasemin , Hanif Sahida , Morris Lorraine , von Wagner Christian
Published: April 2022

Objective

To evaluate the ‘Call for a Kit’ health promotion intervention that was initiated in Lancashire, England to improve bowel cancer screening uptake.

Methods

Within the intervention, screening non-responders are called and invited to attend a consultation with a health promotion team member at their primary care practice. In this audit, we analysed the proportion of those contacted who attended the in-person clinic versus those who received a phone consultation, the number returning a test kit from in-person versus phone consultations, and the extent to which test kit return was moderated by sociodemographic characteristics.

Results

In 2019, 68 practices participated in the intervention which led to 10,772 individuals being contacted; 2464 accepted the invitation to an in-person consultation, of whom 1943 attended. A further 1065 agreed to and attended a consultation over the phone. The 3008 consultations resulted in 2890 test kits being ordered, of which 1608 (55.6%) were returned. The intervention therefore yielded a 14.9% response rate in the total cohort; 71.5% of test kits came from individuals attending the in-person consultation. Women and those registered with a practice in socioeconomically deprived areas were less likely to return the test kit. Individuals with a black, mixed or a non-Indian/Pakistani Asian ethnic background were significantly more likely to accept the offer of an in-person consultation and return the test kit.

Conclusion

Our analysis demonstrated the strong likelihood of people returning a test kit after an in-person appointment but also the usefulness of using phone consultations as a safety net for people unable or unwilling to attend in-person clinics.
Virtual and In-Person Community-Engaged Learning: Is Student Learning Virtually the Same?
Authors: Sweet Castel , Sayre Molly Malany , Bohrer Kelly
Published: April 2022

Background: The COVID-19 pandemic prompted instructors of many community-engaged learning (CEL) courses to utilize virtual CEL as a replacement for in-person CEL. Few assessments indicate whether in-person CEL student learning outcomes (SLOs) can be achieved through virtual CEL. Purpose: This study assesses whether an in-person CEL cohort and a virtual CEL cohort achieved the SLOs for a CEL course. Methodology/Approach: The sample for the study is students in the 2019 in-person CEL cohort (n = 13) and the 2020 virtual CEL cohort (n = 13) of a CEL course. Students’ reflective writing is analyzed using focused coding to evaluate the extent to which students achieved the SLOs. Findings/Conclusions: Findings indicate that both cohorts achieved the SLO about career exploration. The virtual CEL cohort did not as thoroughly achieve SLOs on cultural differences, community leadership, and working with others for local impact. The groups utilized reflective practices differently. In this case, virtual CEL was less effective than in-person CEL. Implications: Virtual CEL is not an exact substitute for in-person CEL. Effectiveness in achieving civic-oriented SLOs is likely to improve through further modification of pedagogical approaches and supplemental content and interactions.
Comparison of visual results and optical quality of two presbyopia-correcting intraocular lenses: TECNIS symfony versus TECNIS synergy
Authors: Shin Da Eun , Lee Hun , Kim Tae-im , Koh Kyungmin
Published: April 2022

Purpose

This study compared the extended depth of focus (EDOF) intraocular lens (IOL) (ZXR00; Tecnis® Symfony®, Johnson & Johnson Vision, Santa Ana, CA, USA) and a new presbyopia-correcting IOL that combines EDOF and multifocal profiles (ZFR00; Tecnis®Synergy®, Johnson & Johnson Vision, Santa Ana, CA, USA) with the same material.

Methods

The medical records of patients undergoing cataract surgery with ZXR00 or ZFR00 implantation between March 2021 and July 2021 and with the data available for the 3-month visit were reviewed. The uncorrected near, intermediate, and distance visual acuity (VA), corrected distance VA, defocus curves, refractive errors (RE), optical quality parameters, and patient-reported visual performance parameters were the main outcome measures.

Results

Among the twenty-three enrolled patients, twelve patients (21 eyes) received ZXR00 and nine patients (17 eyes) received ZFR00. The mean age of the patients was 59.6 ± 10.6 (range: 49 to 70) and 65.2 ± 8.2 (range: 45 to 82) years in ZXR00 and ZFR00 groups, respectively, without significant difference. There was not a significant difference between the two groups in terms of baseline parameters and postoperative RE. The ZFR00 group showed markedly superior intermediate and near VA ( p < 0.001 for all) at 3 months postoperatively. In terms of optical quality, ZXR00 was significantly better than ZFR00 ( p < 0.001).

Conclusions

Both IOLs had comparable distance VA. ZFR00 IOL was superior for intermediate and near visual acuity, but ZXR00 IOL was better for optical quality. Research with more participants is needed to support this finding.

Published: April 2022

The self-healing of micro and macro cracks is vital for eliminating defects such as damage progression and loss of strength in structures. In this study, a polyurethane (PU) based geometrically self-healing sandwich structure was developed. The geometric healing agent, PU resin and activator, were filled into macrocapsules, and these capsules were filled into the Aluminum (Al) honeycomb cells. Self-healing of structural strength, large holes and cracks in developed sandwich structures were investigated by performing quasi-static compression and impact penetration tests. The sandwich structure with a self-healing capsules-filled core was damaged by subjecting it to quasi-static and penetration impact loads, and the healing agents in the broken capsules were mixed. The damage in the specimen was removed by geometric self-healing. Liquid and air permeability tests were applied to the PU foam used as a healing agent. No liquid permeability was observed in the structure. In addition, significant reductions in air permeability were obtained. Scanning electron microscope images were used to explore the characterization of the PU foam structure cells.

Authors: Sousa Marta , Andrade Joana , de Castro-Rodrigues Andreia , Gonçalves Rui Abrunhosa
Published: April 2022

Child sexual abuse is a public health problem of global magnitude with profound and negative consequences for the victims and society. Thus, psychological intervention with individuals who sexually offended against children is crucial for reducing recidivism. Numerous reviews and meta-analyses have shown the effectiveness of psychological interventions in individuals who sexually offended, but few reviews have been done on this subtype of offenders. This article reviews evaluation studies of intervention programs designed to treat individuals who sexually offended against children, providing a more detailed account of treatment procedures. Articles were identified from peer-reviewed databases, bibliographies, and experts. Following full-text review, 12 studies were selected for inclusion by meeting the following criteria: quantitative or qualitative research studies published in English from 2000 to 2020 with titles or abstracts that indicated a focus on treatment effectiveness, detailing the psychological treatment procedures on adult, male individuals convicted for child sexual abuse. Cognitive-behavioral therapy with a relapse prevention approach was the most frequent modality found in child sexual offending treatment. Besides, different criminogenic and non-criminogenic factors emerge as targets for intervention. Study design, study quality, and intervention procedures shortened the accumulation of evidence in treatment effectiveness.
Identification of a circRNA-mediated comprehensive ceRNA network in spinal cord injury pathogenesis
Authors: Zu Chao , Li Jingyuan , He Xijing , Ji Le , Li Xia
Published: April 2022

RNAs are closely associated with human diseases; however, immune-related genes (IRGs) and their potential regulatory networks in relation to spinal cord injury (SCI) are still poorly understood. Here, we investigated the key IRGs as well as the competing endogenous RNA (ceRNA) mechanisms that are associated with SCI pathogenesis based on microarray datasets and the use of a rat SCI model. Specifically, four independent SCI microarray datasets from Gene Expression Omnibus (GEO) database were analyzed and, thereafter, differentially expressed IRGs were annotated via Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. Furthermore, based on the GEO datasets, differentially expressed RNAs (DERNAs), including DEcircRNAs, DEmiRNAs, and DEmRNAs were identified and interactions between them were also predicted using online databases, and to construct a circular RNA (circRNA) mediated ceRNA network, candidate RNAs were also identified. Furthermore, the support vector machine (SVM) and least absolute shrinkage and selection operator (LASSO) methods were used for the identification of critical DERNAs, while differential gene expression was validated using the GSE20907 dataset. Our results were as follows. In the SCI microarray datasets, 32, 58, and 74 DEIRGs, DEcircRNAs, and DEmiRNAs were identified, respectively. In addition, GO and KEGG analyses showed that the DEIRGs were primarily enriched in neutrophil-mediated immunity and nuclear factor-kappa B (NF-κB) and hypoxia-inducible factor-1 (HIF-1) signaling pathways, and based on LASSO and SVM screening, PLXNB2 was identified as a DEIRG, while hsa_circ_0026646 was identified as the key circRNA, showing a higher SCI expression. Furthermore, our results proved that PLXNB2 and hsa_circ_0026646 were upregulated in SCI, whereas miR-331-3p was downregulated, and, interestingly, similar expression profiles were confirmed using the rat SCI model. Furthermore, fluorescent reporter assay indicated that both hsa_circ_0026646 and PLXNB2 have miR-331-3p target sites, and the ceRNA hypothesis suggested the dysregulation of hsa_circ_0026646, miR-331-3p, and PLXNB2 in SCI. Thus, our results suggested that in SCI pathogenesis, hsa_circ_0026646 correlates with PLXNB2 by targeting miR-331-3p.

Authors: Zhang Dong , Hao Wenyan , Li Xujiong , Han Pengyong , Niu Qi
Published: April 2022

New methods to prevent ventilator-induced diaphragmatic dysfunction (VIDD) are urgently needed, and the cellular basis of VIDD is poorly understood. This study evaluated whether transvenous phrenic nerve stimulation (PNS) could prevent VIDD in rabbits undergoing mechanical ventilation (MV) and explored whether oxidative stress-related genes might be candidate molecular markers for VIDD. Twenty-four adult male New Zealand white rabbits were allocated to control, MV, and PNS groups ( n = 8 in each group). Rabbits in the MV and PNS groups underwent MV for 24 h. Intermittent bilateral transvenous PNS was performed in rabbits in the PNS group. Transdiaphragmatic pressure was recorded using balloon catheters. The diameters and cross-sectional areas (CSAs) of types I and II diaphragmatic fibers were measured using immunohistochemistry (IHC) techniques. Genes associated with VIDD were identified by RNA sequencing (RNA-seq), differentially expressed gene (DEG) analysis, and weighted gene co-expression network analysis (WGCNA). Reverse transcription polymerase chain reaction (RT-PCR), Western blotting, and IHC analyses were carried out to verify the transcriptome profile. Pdi60Hz, Pdi80Hz, and Pdi100Hzwere significantly higher in the PNS group than in the MV group at 12 and 24 h ( P < 0.05 at both time points). The diameters and CSAs of types I (slow-twitch) and II (fast-twitch) fibers were significantly larger in the PNS group than in the MV group ( P < 0.05). RNA-seq, RT-PCR, Western blotting, and IHC experiments identified two candidate genes associated with VIDD: Aldh1a1 and Scl25a30. The MV group had significantly higher mRNA and protein expressions of Aldh1a1/ALDH1A1 and significantly lower mRNA and protein expressions of Scl25a30/SCL25A30 than the control or PNS groups ( P < 0.05). We have identified two candidate genes involved in the prevention of VIDD by transvenous PNS. These two key genes may provide a theoretical basis for targeted therapy against VIDD.
Development of Individual Add-On Interventions for Patients With Depression Who are Persistently Not on Track in Group Cognitive Behavioural Therapy: A Protocol for a Treatment Development and Feasibility Study
Authors: Gryesten Jasmin Rejaye , Poulsen Stig , Arnfred Sidse Marie
Published: April 2022

Introduction: Only about half of the patients treated with Cognitive Behavioural Therapy (CBT) for depression are in remission after treatment. Progress monitoring during therapy, supplemented with clinical support tools, has shown promising results with regard to improving outcome, but results for group psychotherapy are less favourable. Therefore, we propose supplementary individual therapy as a possible solution to lack of progress in group CBT. The current study seeks to develop a brief add-on course of personalized individual therapy for patients showing lack of improvement during CBT group therapy. Methods and analysis: We aim to develop an intervention that includes progress monitoring, clinical support tools and a selection of patient-centred add-on interventions. An initial multiple case study will involve patients treated for depression in group CBT. The patients will perform progress monitoring every week, and therapists will receive alerts when a patient is not improving. Analyses will integrate qualitative data on the experiences of therapists and patients, quantitative tracking data, and initial clinical assessments. Based on these analyses, the proposed add-on interventions will be further developed and offered to the patients who are persistently not improving (pNOT) in three new CBT groups, which will be monitored as described above. Interviews will be performed with patients and therapists to explore their experiences of the new interventions. Qualitative data will be analysed through thematic analysis, and Single Case Experimental Design analyses will be made based on daily tracking of WHO-5.
Utility of paclitaxel-coated balloons for the treatment of infrainguinal disease in the Asian population – 24-month outcome data from the BIOLUX P-III Global Registry 24-month Asian outcomes of BIOLUX P-III
Authors: Linn Yun Le , Wang John CC , Pua Uei , Yahaya Shaiful AB , Choke Edward TC , Chong Tze-Tec , Brodmann Marianne , Tang Tjun-Yip
Published: April 2022

Background

Results from the BIOLUX P-III registry have demonstrated favourable outcomes of Passeo-18 Lux™ (Biotronik®, Buelach, Switzerland) drug-coated balloon in treating obstructive infrainguinal peripheral artery disease, but it has not been established if Asians would benefit to the same extent as non-Asians.

Methods

A subgroup analysis was performed on the 24-month data comparing the Asian cohort (AC) to non-Asian cohort (NAC).

Results

AC included 49 patients with 77 lesions. AC was significantly younger (65.6 vs 70.3 years, p < 0.05), had more diabetes (87.8% vs 45.3%, p < 0.05), and was more likely to present with CLTI (73.5% vs 35.3%, p < 0.001) compared to NAC. They had significantly longer mean target lesions (115 vs 86.9 mm, p = 0.006), and received significantly higher paclitaxel doses (10.7 vs 7.2 mg, p = 0.0005). Device, technical and procedural successes were 125/125(100%), 95/97(97.5%) and 45/49(91.8%), respectively. There was no significant difference in target lesion revascularization rates between groups (10.5% vs 12%, p = 0.91). However, the AC had more major adverse events (30.2% vs 16.1%, p = 0.001), amputations (26.3% vs 6.2%, p < 0.05) and mortality (37.9% vs 10.6%, p < 0.05) at 24 months.

Conclusion

Passeo-18 Lux™ use was efficacious in Asians, but was associated with higher adverse events, amputations and mortality rates, likely attributable to poorer patient comorbidities and more extensive PAD.
Online paths planning method for unmanned surface vehicles based on rapidly exploring random tree and a cooperative potential field
Authors: Wen Naifeng , Zhao Lingling , Zhang Ru-Bo , Wang Shuai , Liu Guanqun , Wu Junwei , Wang Liyuan
Published: April 2022

The unstructured, dynamic marine environmental information and the cooperative obstacle avoidance problem greatly challenge the online path planner for unmanned surface vehicles. Efficiency and optimization are crucial for online path planning schemes. Thus, we proposed an algorithmic combination of the optimal rapidly exploring random tree and artificial potential field methods. First, we built a repulsive potential field by considering the relative velocity and position of the unmanned surface vehicle to obstacles and the international regulations for preventing collisions at sea, wherein we designed a repulsive force calculation method using radar readings to avoid irregular obstacles. Then, we guided the sampling process of rapidly exploring random tree using the potential field to accelerate the convergence rate of rapidly exploring random tree to low-cost obstacle avoidance paths. Finally, we planned for multiple paths based on the leader–follower architecture with the guidance of a cooperative potential field. In the experiments, the proposed method consistently outperformed the benchmark methods. We also verified the effectiveness of the algorithmic modifications by conducting ablation experiments.
From dealing to influencing: Online marketing of cannabis on Instagram
Authors: Anderdal Bakken Silje , Kirstine Harder Sidsel
Published: April 2022

In this paper we argue that legal and technological shifts in cannabis marketing has a gendered impact, which research so far has ignored. Despite high variations in national criminal laws, US-based social media platforms like Instagram, Facebook, and Twitter play a huge role in enforcing certain social and political standpoints on a global scale. One example being the recent legalization and commercialization of cannabis in various states in the US. Young men with dark, anonymous profiles illegally dealing cannabis on social media are no longer the only visible traders, as today’s marketing of trademarked legal cannabis products also features women influencers, who post images exhibiting light colors, desirable environments, and beautiful landscapes. To understand this diversity, we compared 60 Instagram profiles of illegal Swedish cannabis sellers to 70 US-based cannabis influencers’ Instagram profiles. By applying theories and research from media scholars on influencing, we highlight various changes in the way cannabis is being presented and professionalized by a new group of actors. Our findings show that cannabis influencers on Instagram are changing the stereotypical characteristics of illegal cannabis culture as being almost entirely dominated by men, to one where cannabis is represented as a desirable accessory in certain feminine lifestyles. Influencers’ role in transforming cannabis culture to become more mainstream and acceptable for women could potentially effect cannabis cultures globally, as well as ongoing legalization debates.
Research on reliability analysis strategy of high-speed train ATP on-board equipment under uncertain information
Authors: Zhang Zhenhai , Wang Yuerong
Published: April 2022

In view of the incomplete knowledge and lack of data, the system has epistemic uncertainties. This paper uses Bayesian network fusion evidence theory to analyze the reliability of high-speed railway ATP on-board equipment. According to the requirements of safety-critical system reliability analysis, this paper starts with the analysis of system structure and unit module status, comprehensively considering the influence of uncertain information, common cause failure, recovery mechanism, and degraded operation on system reliability. In this paper, with the advantage of the Bayesian network in the description of events in multiple states, evidence theory is used to reason about the system under incomplete information conditions, obtain the availability interval of on-board subsystems and discuss the impact of the degraded operation on system availability. The [Formula: see text] factor model is used to analyze common cause failures, and then the Bayesian network modeling of common cause failures is realized by adding common cause failure nodes. The results show that the method enhances the Bayesian network’s ability to process uncertain information, and the common cause failure data of the train control on-board subsystem is continuously accumulated. The factor model can be used to obtain a more practical common cause failure rate.
Investigating the role of social media abuse in gender-based violence: The experiences of women police officers
Authors: Watson Susan
Published: April 2022

Online abuse communicated via social networking sites has increased considerably in recent years, with a significant amount of pejorative communication targeted at women. This mixed methods research study investigates the online abuse received by women police officers in the course of their work. The study considers how the abuse received in the online space echoes other forms of gender-based violence, drawing upon evidence gathered from semi-structured interviews with serving senior police officers in England and Wales. The research has devised a seven-element framework to demonstrate that the online abuse directed at women is misogynistic, frequently includes violent threats and dismisses female contributions to online discussions. The study also reveals that the abuse directed at women varies significantly, depending on occupation, with women police officers more likely to receive abuse that questions their ability or criticises their appearance.
Stability criteria of two-port networks, application to thermo-acoustic systems

Published: April 2022

System theory methods are developed and applied to introduce a new analysis methodology based on the stability criteria of active two-ports, to the problem of thermo-acoustic instability in a combustion appliance. The analogy between thermo-acoustics of combustion and small-signal operation of microwave amplifiers is utilized. Notions of unconditional and conditional stabilities of an (active) two-port, representing a burner with flame, are introduced and analyzed. Unconditional stability of two-port means the absence of autonomous oscillation at any embedding of the given two-port by any passive network at the system's upstream (source) and downstream (load) sides. It has been shown that for velocity-sensitive compact burners in the limit of zero Mach number, the criteria of unconditional stability cannot be fulfilled. The analysis is performed in the spirit of a known criterion in microwave network theory, the so-called Edwards-Sinsky's criterion. Therefore, two methods have been applied to elucidate the necessary and sufficient conditions of a linear active two-port system to be conditionally stable. The first method is a new algebraic technique to prove and derive the conditional and unconditional stability criteria, and the second method is based on certain properties of Mobius (bilinear) transformations for combinations of reflection coefficients and scattering matrix of (active) two-ports. The developed framework allows formulating design requirements for the stabilization of operation of a combustion appliance via purposeful modifications of either the burner properties or/and of its acoustic embeddings. The analytical derivations have been examined in a case study to show the power of the methodology in the thermo-acoustics system application.
Management of nondysplastic Barrett’s esophagus: When to survey? When to ablate?

Published: April 2022

Barrett’s esophagus (BE), a precursor for esophageal adenocarcinoma (EAC), is defined as salmon-colored mucosa extending more than 1 cm proximal to the gastroesophageal junction with histological evidence of intestinal metaplasia. The actual risk of EAC in nondysplastic Barrett’s esophagus (NDBE) is low with an annual incidence of 0.3%. The mainstay in the management of NDBE is control of gastroesophageal reflux disease (GERD) along with enrollment in surveillance programs. The current recommendation for surveillance is four-quadrant biopsies every 2 cm (or 1 cm in known or suspected dysplasia) followed by biopsy of mucosal irregularity (nodules, ulcers, or other visible lesions) performed at 3- to 5-year intervals. Challenges to surveillance include missed cancers, suboptimal adherence to surveillance guidelines, and lack of strong evidence for efficacy. There is minimal role for endoscopic eradication therapy in NDBE. The role for enhanced imaging techniques, artificial intelligence, and risk prediction models using clinical data and molecular markers is evolving.

Published: April 2022

Orofacial epidermoid cysts are rare entities that present as encapsulated, subepidermal painless masses, usually slow growing and asymptomatic. They are mostly limited to the floor of the mouth, tongue, lips, palate or jaws. Herein, we present an atypical case of epidermoid cyst originating from the left cheek facial epidermis in a 27-year-old male patient. The cyst presented as a swelling that was slowly progressing in size since the past 1 year with no discharge. Complete excision of the mass was done, and the cyst cavity was found to be filled with a cheesy-white, granular, semi-solid proteinaceous exudate which completely occluded the punctum. The patient post-operatively revealed persistent mechanical trauma due to incorrect workplace habits he developed, which led to the formation of the epidermoid cyst. Patient education was done and was advised to use proper workplace instrumentation.
Revisiting Proficiency Pairing in Collaborative Writing From an Equity Theory Perspective: Voices From High-Proficiency EFL Learners
Authors: Chen Wenting , Lee Yueh-Ting
Published: April 2022

Although research on proficiency pairing for collaborative writing in second language (L2) or foreign language (FL) higher education has proliferated in the last few decades, scant attention has been paid to students’ perceptions about how they are paired up. This case study revisited proficiency pairing in light of equity theory, examining two high proficiency Chinese EFL learners’ perceptions of proficiency pairing and how their perceptions affected their actions in the collaborative writing process. The findings reveal that students with similar advanced L2 proficiency behaved differently during a collaborative writing process due to their different perceptions of proficiency pairing. This study also found that motivation, perceived self-value, and collaborative writing assessment were three major factors that shaped students’ perceptions of proficiency pairing. This study provides useful insights into methods for pairing learners in L2 writing classes and improving teacher education in L2 higher educational contexts.
City Administrative Level and Tertiary Educational Opportunities: Evidence From China’s Higher Education Expansion Policy
Authors: Dong Yueyan , Yu Nannan , Hong Tao , Yue Jinxing
Published: April 2022

In 1999, the Chinese government implemented a higher education enrollment expansion policy to improve education equality. Now, its positive impact on educational equality is contested. This study attempts to identify the link between city administrative level and tertiary attainment in the context of the policy. Our empirical findings indicate that after implementation of the policy, inequality increased. Students from political and economic centers had more opportunities for tertiary education attainment. This policy has a greater impact on disparities in access to undergraduate education for individuals living in different administrative hierarchies than it does on specialist education.
Trends and Methods of Suicide in Italy, 1979 to 2016
Authors: Terranova Claudio
Published: April 2022

The epidemiology of suicide could provide interesting data for societies that are undergoing significant demographic transformations. The main purpose of this study was to analyze the scale of and trends in suicide in Italy during the period 1979 to 2016. The secondary aim was to compare rates and methods of suicide in the elderly with those in other age groups. This was a population-based study on suicide for the period 1979 to 2016. Data on suicide regarding gender and age from the Italian Institute of Statistics and the World Health Organization were examined with linear regression and ANOVA test. The data on the elderly were compared with those for other age groups. Linear regression revealed a significant decline in the overall suicide rate ( F = 180.6; p < .0001). The 45 to 54 age group accounted for the highest suicide rate in recent years (2003–2016). The second highest incidence was among the elderly, with the “young” elderly (65–75 years old) having the highest suicide rate in this group. The male-to-female suicide ratio increased proportionally with age. Hanging was the suicide method most frequently employed independently from age groups. Universal and selective preventive strategies could be developed on the basis of the results of this study. The sensitization of health professionals, families, and friends to specific circumstances could contribute to the decline in the incidence of suicide in specific circumstances of time and place. Further studies are needed in order to better understand social and clinical risk factors related to the risk of suicide in specific age groups.

Published: April 2022

This study aims to investigate the influence of students’ knowledge, attitude, and behavioral intention on their behaviors during the COVID-19 pandemic. A survey study was designed using an online questionnaire involving 653 respondents from the first to final-year students at a Malaysian university. A CACQ-COV instrument was designed based on the Theory of Reasoned Action (TRA) model, comprising 67 items in four constructs: students’ knowledge of the current pandemic, emotional engagement, behavioral intention, and behavioral action. The results show that the students learn most about the COVID-19 pandemic from the media and the internet platform; more than 50% of the students rated the television broadcast as the most trusted media. The mean scores of the students’ knowledge about COVID-19 facts and symptoms; emotion, intention, and action are at high levels. In addition, knowledge, emotion, and behavioral intention have significantly influenced the students’ behaviors and actions; it is noted that emotion has the greatest influence compared with knowledge and behavioral intention. The implication is that television broadcast should be the primary choice of media for carrying out future mass campaigns, in preference to social media, especially for announcing urgent matters and disseminating information related to the current issues.

Authors: Zhu Haoran , Lei Lei
Published: April 2022

Text Classification (TC) is the process of assigning several different categories to a set of texts. This study aims to evaluate the state of the arts of TC studies. Firstly, TC-related publications indexed in Web of Science were selected as data. In total, 3,121 TC-related publications were published in 760 journals between 2000 and 2020. Then, the bibliographic information was mined to identify the publication trends, important contributors, publication venues, and involved disciplines. Besides, a thematic analysis was performed to extract topics with increasing/decreasing popularity. The findings showed that TC has become a fast-growing interdisciplinary area, and that emerging research powers such as China are playing increasingly important roles in TC research. Moreover, the thematic analysis showed increased interest in topics concerning advanced classification algorithms, performance evaluation methods, and the practical applications of TC. This study will help researchers recognize the recent trends in the area.
