Antisemitism in the global populist international
Authors: Subotic Jelena
Published: December 2021

This article explores the relationship between antisemitism and international politics, specifically the potent role that antisemitism plays in the development and maintenance of the global populist international. After briefly sketching the history of modern transnational antisemitism, I make two principal arguments for why antisemitism should be of more direct concern for the scholarship of International Relations. First, antisemitism serves as a powerful interpretive framework for contemporary far-right populist movements that are challenging the current international order. Second, antisemitism is shaping the formation of new international alliances. The strategic use of antisemitism in far-right populist foreign policy has changed, as evidenced in the increasing decoupling of attitudes towards Israel from antisemitism against diaspora Jews and a rise in pro-Israel policies of far-right antisemitic parties and movements. I conclude by reasserting that International Relations should understand antisemitism as one of the interpretive foundations of the global illiberal resurgence.

Aim:

We investigated factors associated with the initiation and continuation of snus use in adolescents in Norway. The associations with adolescents’ own educational plans, the parents’ educational level(s) and tobacco habits were estimated.

Methods:

In this cross-sectional questionnaire-based study, 1465 patients aged 18–20 years participated. The questionnaire was administered at regular dental examinations in the public dental health service. To assess the association between individual factors and the initiation of tobacco habits, a generalised structural equation model with random effects at the clinic level was used. Binary responses were modelled using multilevel binary logistic regression, while the number of snus boxes used per month was modelled using a multilevel Poisson regression model.

Results:

Of current (daily and occasional) tobacco users, 85% were snus users, including dual users of both snus and cigarettes. The median age of snus initiation was 16 years. Both parental snus use and smoking were associated with an increased risk of snus initiation, snus use and a higher amount of use. An increased risk of using snus was associated with male gender and with no educational plans or planning for further vocational education. The amount of snus used was higher among current snus users with a prior smoking history and among those planning for further vocational education.

Conclusions:

These findings may aid in developing and targeting tobacco prevention strategies aimed at young people. Tobacco prevention measures should start at the elementary school level. The strong association with parental tobacco habits underlines the importance of parents’ influence on their children’s tobacco use.
An optimal control method for time-delay feedback control of 1/4 vehicle active suspension under random excitation
Authors: Wu Kaiwei , Ren Chuanbo , Chen Yuanchang
Published: December 2021

Time-delay feedback control can effectively broaden the damping frequency band and improve the damping efficiency. However, the existing time-delay feedback control strategy has no obvious effect on multi-frequency random excitation vibration reduction control. That is, when the frequency of external excitation is more complicated, there is no better way to obtain the best time-delay feedback control parameters. To overcome this issue, this paper is the first work of proposing an optimal calculation method that introduces stochastic excitation into the process of solving the delay feedback control parameters. It is a time-delay control parameter with a better damping effect for random excitation. In this paper, a 2 DOF one-quarter vehicle suspension model with time-delay is studied. First, the stability interval of time-delay feedback control parameters is solved by using the Lyapunov stability theory. Second, the optimal control parameters of the time-delay feedback control under random excitation are solved by particle swarm optimization (PSO). Finally, the simulation models of a one-quarter vehicle suspension simulation model are established. Random excitation and harmonic excitation are used as inputs. The response of the vehicle body under the frequency domain damping control method and the proposed control method is compared and simulated. To make the control precision higher and the solution speed faster, this paper simulates the model by using the precise integration method of transient history. The simulation results show that the acceleration of the vehicle body in the proposed control method is 13.05% less than the passive vibration absorber under random excitation. Compared with the time-delay feedback control optimized by frequency response function, the damping effect is 12.99%. The results show that the vibration displacement, vibration velocity, and vibration acceleration of the vehicle body are better than the frequency domain function optimization method, whether it is harmonic excitation or random excitation. The ride comfort of the vehicle is improved obviously. It provides a valuable tool for time-delay vibration reduction control under random excitation.
Bending-torsional-axial-pendular nonlinear dynamic modeling and frequency response analysis of a marine double-helical gear drive system considering backlash
Authors: Dong Hao , Bi Yue , Wen bo , Liu Zhen-bin , Wang Li-bang
Published: December 2021

The double-helical gear system was widely used in ship transmission. In order to study the influence of backlash on the nonlinear frequency response characteristics of marine double-helical gear system, according to the structural characteristics of double-helical gear transmission, considering the time-varying meshing stiffness, backlash, damping, comprehensive transmission error, external load excitation, and other factors, a three-dimensional bending-torsional-axial-pendular coupling nonlinear dynamic modeling and dynamic differential equation of 24-DOF double-helical gear transmission system were established. The Runge–Kutta numerical method was used to analyze the influence of backlash, time-varying meshing stiffness, damping, error and external load excitation on the amplitude frequency characteristics. The results show that the backlash can cause the runout of the double-helical gear system, and the system has first harmonic and second harmonic response. With the increase of backlash, the amplitude of the system increases and the jumping phenomenon remains unchanged. The amplitude frequency response of the system is stimulated by time-varying meshing stiffness and comprehensive transmission error, and restrained by damping and external load excitation. The vibration displacement amplitude of the system increases with the increase of vibration displacement and has little effect on the state change of the system. The vibration test of double-helical gear is carried out. The frequency response components obtained by numerical simulation are basically consistent with the experimental results, which proves the correctness of the theoretical calculation. It provides a technical basis for the study of vibration and noise reduction performance of double-helical gear.
Utilising police knowledge and skills: Experiences from police practitioners studying a police specific degree
Authors: Norman Jenny , Fleming Jenny
Published: December 2021

This article presents preliminary findings from a longitudinal study contributing to the current debate about police education and professionalising the police in England and Wales. The findings in this article are taken from a survey administered in 2016 to third-year students enrolled in a policing degree. Surveys were distributed to police officer students in the last year of their degree programme asking for their perceptions of the degree, their organisation's support for their learning and how they felt that learning was utilised in their workplace. Supplementary to the survey, interviews were conducted with the students after their graduation in 2018. The research findings suggest that students perceived the benefits of obtaining a degree-level qualification as fundamentally important to their professional development and personal decision-making at work. Early support initially received for study leave purposes, rarely extended beyond this practical provision. The extent to which police organisations valued the learning from the degree was perceived to be lacking. Senior-ranked students were more likely to be able to use and promote their newly acquired skills and knowledge in the workplace compared with lower-ranked students. Such findings may inform scholars’ and practitioners’ continued evaluation of police education reforms in England and Wales.
Dynamics of moving-object grasped by a hybrid hand
Authors: Lu Yi , Chang Zefeng , Ye Nijia
Published: December 2021

When a heavy object is cooperatively grasped to move by several fingers of the robot hybrid hand, the inertial properties and the mass distribution of the object must influence largely on the operation precision, grasping stability, and the safety of both the hybrid hand and the object. Hence, it is an important and significant issue to establish and analyze the dynamics model of the moving-object cooperatively grasped by the hybrid hand in order to ensure the safety and grasping stability of the hybrid hand and the object. However, this research has not been conducted. In this paper, a dynamics model of the moving-object grasped by the hybrid hand is established, and its dynamics is studied and analyzed. First, a three-dimensional model of a hybrid hand formed by a novel parallel manipulator and three fingers is designed for cooperatively grasping object. Second, the kinematic formulas for solving the Jacobian matrices, the Hessian matrices, the general velocity/acceleration of the moving platform, and four active limbs of the parallel manipulator are derived. Third, the composite Jacobian matrix and the composite Hessian matrix of the hybrid hand are derived, and the general velocity/acceleration of the moving-object grasped by the hybrid hand is derived. Fourth, dynamics model of the hybrid hand is established, the formulas for solving the dynamic actuation forces of the three fingers and the dynamic actuation forces/torque and constrained forces of the parallel manipulator are derived. Finally, the theoretical solutions of the dynamics model of the moving-object grasped by the hybrid hand are verified by its simulation mechanism.
Oscillation control of a pendulum structure using an inverted pendulum-type tuned mass damper
Authors: Nguyen Duy-Chinh
Published: December 2021

In reality, a pendulum structure can be used to model many real structures as a ropeway carrier, crane, balloon basket or ships in waves, etc, which often hung on moving points such as cables, wavefronts and balloons, etc. To the best knowledge of the author, however, there is no study to control oscillation of the pendulum structure excited by the hanging point. Therefore, this article deals with the oscillation control of the pendulum structure by using an inverted pendulum-type tuned mass damper, in which the system is subjected to the motion of the hanging point. In particular, the optimal parameters are determined in clear analytical solutions, making it easy for scientists to determine the optimal parameters to suppress the oscillation for the pendulum structure.
Mitigating the consequences of negative news: How constructive journalism enhances self-efficacy and news credibility
Authors: Overgaard Christian Staal Bruun
Published: December 2021

An informed electorate is vital for a well-functioning democracy. Yet many citizens intentionally avoid the news because it evokes negative feelings of disempowerment and distrust. This study ( n = 270) investigated how social media exposure to a new journalistic approach, constructive journalism, influences news consumers. The results showed that constructive social media posts, as compared to negative posts, led to higher levels of positive affect, self-efficacy, and perceived news credibility. In line with the broaden-and-build theory of positive emotions, the effects on self-efficacy and news credibility were mediated by positive affect. A similar mediating role was found for negative affect, counter to the theoretical expectations. These findings shed new light on the broaden-and-build theory, suggesting parts of it generalize to the context of news exposure on social media. The findings also suggest that constructive journalism may be an effective way to mitigate some of the main drivers of news avoidance in the 21st century.
“Toxic atmosphere effect”: Uncivil online comments cue negative audience perceptions of news outlet credibility
Authors: Masullo Gina M , Tenenboim Ori , Lu Shuning
Published: December 2021

Uncivil user comments have been found to have a negative effect on how people perceive an issue featured in the news, a news story, or a journalist who reports a news story. To advance this line of research, we draw on expectancy violations theory and the concept of heuristic cues to theorize the toxic atmosphere effect. We theorize that incivility in online comment threads could pose an even larger challenge to news organizations by cuing news audience members to perceive an entire news outlet—not just an individual story—as lacking in credibility. Based on two experiments in the United States (Study 1, n = 520; Study 2, n = 1056), we show that exposure to incivility can lead people to perceive a news outlet as less credible even though the incivility did not directly attack the news outlet. Such effects hold true even when people are exposed to comment threads in which the first several comments are civil. Democratic and business implications are discussed.

Published: December 2021

This paper introduces a comprehensive and systematic Design of Experiments based methodology deployed in conjunction with a multi-physics engine air-path and combustion co-simulation, leading to the development of a global transient simulation capability for engine out NOx emissions. The proposed multi-physics engine simulation framework couples a real-time one-dimensional air flow model with a Probability Density Function based Stochastic Reactor Model that accounts for detailed in-cylinder combustion chemistry to predict combustion emissions. The integration challenge stemming from the different computation complexities and time scales required to ensure adequate fidelity levels across multi-physics simulations was addressed through a comprehensive Design of Experiments methodology to develop a reduction of the slower Stochastic Reactor Model simulation to enable a transient simulation focussed on NOx emissions. The Design of Experiments methodology, based on Optimal Latin Hypercube design experiments, was deployed on the multi-physics engine co-simulation platform and systematically validated against both steady state and transient light-duty Diesel engine test data. The surrogate selection process included the evaluation of a range of metamodels, with Kriging metamodels selected based on both the statistical performance criteria and consideration of physical phenomena trends. The transient validation was carried out on a simulated New European Drive Cycle against the experimental data available, showing good capability to capture transient NOx emission behaviour in terms of trends and values. The significance of the results is that it proves the transient and drive cycle capability of the multi-physics simulation platform, suggesting a promising potential applicability for early powertrain development work focussed on drive cycle emissions.
Fusion of horizons: Realizing a meaningful understanding in qualitative research
Authors: Bartley Kevin A , Brooks Jeffrey J
Published: December 2021

This paper explores a case example of qualitative research that applied productive hermeneutics and the central concept, fusion of horizons. Interpretation of meaning is a fusing of the researchers’ and subjects’ perspectives and serves to expand understanding. The purpose is to illustrate an exemplar of qualitative research without establishing a rigid recipe of methodology. The illustration is based on in-depth observational and textual data from an applied anthropological study conducted in western Alaska with Yup’ik hunters and fishers and government agency employees as they worked towards collaborative management. The metaphor of the hermeneutical circle is showcased to help the reader understand the philosophical underpinnings and the analytical processes used to realize a meaningful interpretation. A series of organizing systems for the interpretation is described, culminating in a final organizing system to communicate a fully realized understanding of collaborative management at the time.
Risk, worry and motivation: How is public knowledge of dementia shaped?
Authors: Ashworth Rosalie , Bassett Zoe , Webb Jake , Savage Sharon
Published: December 2021

Background and Objectives

Due to the concern over global rising rates of dementia, increased emphasis has been placed on understanding and moulding the public’s knowledge and awareness of the condition. There has been limited previous research into predictors of dementia knowledge; overall knowledge amongst the public is low, and it has been widely agreed that more needs to be done to raise awareness of this condition. This study seeks to solidify understanding of public dementia knowledge and introduces dementia worry, motivation to seek information and risk perception as novel concomitants of this knowledge.

Research Design and Methods

A convenience sample of 311 UK adults completed a survey on dementia knowledge including Alzheimer’s disease-specific questions, worry about developing dementia, motivation to seek information and perceived personal risk of getting the disease. Surveys were completed face-to-face and included both closed and open-ended questions.

Results

Overall dementia knowledge scores were low, achieving an average of 33% of the total possible score, with 88% of the sample scoring below 50%. Bivariate correlations were performed between dementia knowledge and key variables, revealing significant positive relationships with risk perception ( r = 0.179, p = .002), worry ( r = 0.140, p = .016) and motivation to seek information ( r = 0.139, p = .016). When knowledge was dichotomised into high and low, worry about ( p = .28) and perceived risk ( p = .19) of dementia was significantly lower for people with low knowledge scores than for people with higher dementia knowledge scores. Motivation to seek information was not significantly different between the high and low knowledge groups ( p = .071).

Discussion and Implications

Despite the relatively low knowledge scores, findings show a positive relationship between modifiable factors and dementia knowledge, suggesting areas to consider for both further research and publication campaigns. Further implications and limitations of this study are discussed.
Eating to become ‘good’ citizens: exploring the visceral biopolitics of eating in Singapore
Authors: Shee Siew Ying
Published: December 2021

This paper develops a more-than-representational approach to consumer agency in food biopolitics that is sensitive to people’s everyday eating experiences. In recent years, studies of food biopolitics have engaged with questions of agency by examining how socially constructed ideas of ‘good’ eating and citizenship are engaged on the ground. Yet, there remain opportunities to depart from the evaluative mind as a dominant site of ethical self-formation, and engage with the body as a site of political action and agency. In this paper, I argue that people’s sense of citizen selves has long been, and continue to be, organised across the interplay of material, discursive, and visceral spaces of eating. I develop this argument by drawing on a critical analysis of historical and contemporary news forums related to public eating in Singapore. For many consumers, their disdain for certain food—ranging from the erstwhile state-vaunted meal plans to leftover food on public dining tables—express an embodied agency in negotiating the technocratic designs of citizenship. In developing a visceral biopolitics of eating, this paper aims to expand understandings of consumers’ capacity in negotiating the ethical tensions between hegemonic imaginings of ‘good’ citizens and the everyday pleasures of eating. Approaching consumer agency this way orientates critical yet oft-overlooked attention to the body’s capacity to act, and possibly effect change, within the broader workings of dietary bio-power.
A comprehensive investigation into the performance of genetic algorithm for effective shipyard topological layout
Authors: Türk Abdullah , Gürgen Samet , Ozkok Murat , Altin İsmail
Published: December 2021

Shipyards have large departments or facilities. It is essential to make an effective topological layout plan since the initial investment cost of these departments is high. Topological layout is an optimization problem and Genetic Algorithm (GA) is generally used in the literature. The selection of effective genetic algorithm approaches and operators are very important to improve the performance of the optimization. This study investigates an effective solution to the shipyard topological layout using a Quadratic Assignment Problem (QAP) model with classic and elitist GA approaches. Besides, genetic operators that have significant effects on exploitation and exploration capabilities are analyzed. Therefore, 126 experiments were run with 13 different operators. The results obtained from the classic and elitist GA approach were evaluated individually and compared with each other. It was observed that the elitist GA approach has a superior performance compared to the classic GA approach. This study is the most comprehensive and practical study on the performance of the GA for topological layout of the shipyard in the literature.
High resolution bolt pre-load looseness monitoring using coda wave interferometry
Authors: Chen Dongdong , Huo Linsheng , Song Gangbing
Published: December 2021

This paper proposes a new concept, named the Detectable Resolution of Bolt Pre-load (DRBP), by using the coda wave interferometry (CWI) to quantitatively measure the pre-load looseness at a high resolution. Due to its characteristics of roughness, irregularity, and randomly distributed asperities, the contact surface of the bolted components can function as a natural interferometer to scatter the propagation waves. The multiply-scattered coda waves can amplify the slight changes in the travel path and show the visible perturbation in the time domain. By calculating the time-shifted correlation coefficient of coda waves before and after the slight pre-load looseness, the tiny pre-load changes can be clearly revealed. To evaluate the feasibility of the proposed method, a theoretical model considering the time shifts of coda waves and the variations of pre-load is established. Based on the acoustoelastic effect and the wave path summation theory of coda wave interferometry, the model shows that the time shifts of coda waves change linearly with the variations of pre-load. Verification experiments are conducted, and the results show that the R-square values of the fitting curves are larger than 0.9216. In addition, the proposed approach has the feature of high resolution. The ultimate pre-load resolution of the proposed approach is 0.331%, that is, when the variation of pre-load is larger than 0.331%, it can be detected. Therefore, theoretical analysis and experimental results prove that the CWI-based pre-load detection approach holds great potential for the detection of bolt pre-load looseness, especially during the initial stage.
The postdigital turn: Philosophy, education, research
Authors: Jandrić Petar , Knox Jeremy
Published: December 2021

This article develops a post-determinist and a post-instrumentalist understanding of education and educational research through the lens of postdigital theory. We begin with historicizing current postdigital research by showing its intellectual ancestry and recognizing its rapidly changing nature. We move on to current state of the art, which we present in three wide themes. The first theme is the great convergence of various lower-level techno-scientific convergences, such as analogue–digital, physics–biology, and biology–information, which results in new epistemologies, ontologies and practices. The second theme is some consequences of the great convergence for education and pedagogy, which result in new postdigital ecopedagogies. The third theme is postdigital research, which is reconfigured by the great convergence towards a closer collaboration between traditional scientific fields and disciplines. We briefly outline four such reconfigurations (multidisciplinary, interdisciplinarity, transdisciplinarity, and antidisciplinarity) and their implications. The article concludes with a brief list of directions for future work in the field.
Does The Betting Industry Price Gender? Evidence from Professional Tennis
Authors: Barrutiabengoa Joxe Maria , Corredor Pilar , Muga Luis
Published: December 2021

This research addresses the importance of gender in the pricing process of the sports betting industry. Specifically, we investigate the impact of gender in the prices that bookmakers offer for tennis matches. Despite widespread evidence of gender bias both in the practice of the sport and its media coverage, tennis is one of the sports that has done most to achieve equality. The analysis of 51,881 tennis matches reveals that betting firms quote higher prices for women's matches than for men's, even when considering uncertainty due to the surprise factor and the media attention. The separate analysis of two bookmakers strengthens the evidence for the role of media attention as a source of gender-related information asymmetry.

Published: December 2021

Drilling is a secondary material removal and usually carried out to facilitate fastening of parts together. Drilling of composite materials is not usually a problem-free process. Issues related to delamination composite laminates need to be addressed because it introduces the stress concentration point on the composite. This study focussed on the influence of process parameters such as spindle speed, feed rate, type of drill bits and geometry on the extend of delamination experienced by the composite during the drilling process of kenaf-glass fibre-reinforced unsaturated polyester composite, and the delamination measurements were taken under a microscope. Taguchi methods and analysis of variance were employed to find the optimal parameters. From the results, the most significant parameter was the feed rate. The minimum delamination was achieved when the feed rate was 0.05 mm/rev and spindle speed was 700r/min using both types of drill bits. The quality of the drill hole using the twist drill bit has been proven to be better than the brad drill bit.

Published: December 2021

Plant fiber reinforced hybrid polymer composites have had broad applications recently because of their lower cost advantages, lower weight, and biodegradable nature. The present work studies the influence of reinforcing giant reed fiber concentration in polyethylene terephthalate (PET) polymer for their physical, mechanical, and thermal characteristics and determines the optimum loading of giant reed fiber using an artificial neural network (ANN) scheme. Giant reed fiber reinforced PET matrix laminates were manufactured from compression molding with different fiber loadings such as 5 wt.%, 10 wt.%, and 20 wt.%. The mechanical characteristics such as tensile and flexural strength and the laminate’s tensile and flexural modulus were appraised and examined. The maximum value of tensile strength, flexural strength, tensile modulus, and flexural modulus were 5.4 MPa, 26 MPa, 8343 MPa, and 6300 MPa, respectively, for PET2 (10 wt.% of giant reed fiber in PET polymer) composite. Fiber pullout, gaps, and fracture behavior were examined from a scanning electron microscope in the microstructural analysis. A machine learning technique has been recommended to combine artificial intelligence while designing giant reed fiber reinforced polymeric laminates. Using the suggested method, an ANN model has been generated to attain the targeted giant reed fiber concentration for PET composite while gratifying the necessary targeted characteristics. The developed method is very effective and decreases the effort and time of material characterization for huge specimens. It will support the researchers in designing their forthcoming test efficiently.
From Personal Responsibility to Political Mobilization: Using Attribution Frames to Overcome Policy Feedback Effects
Authors: SoRelle Mallory E.
Published: December 2021

Public policies that promote personal responsibility while minimizing government responsibility are a key feature of modern American political economy. They can decrease Americans’ political participation on a given issue, with detrimental consequences for the wellbeing of economically insecure families. Can this pattern be overcome? I argue that attribution frames highlighting government’s role in and responsibility for policies may increase people’s propensity for political action on an issue, but only if the frame can increase the salience of their preexisting beliefs about government intervention. Drawing on the case of consumer financial protection, I administer an experiment to determine the effect of attribution framing on people’s willingness to act in support of a popular banking reform. I find that helping people draw parallels between an issue they feel responsibility for and one they accept government responsibility for can boost political engagement on behalf of the original policy.
Retrograde Superior Mesenteric Artery Stenting in Case of SMA Shuttering
Authors: Zhang Jason , Basu Rohan , Gaffey Ann , Glaser Julia , Kalapatapu Venkat
Published: December 2021

This case describes a patient who underwent endovascular repair for an extent V thoracoabdominal aneurysm with planned coverage of the celiac artery. Following deployment of the stent graft, the superior mesenteric artery was shuttered, and the patient subsequently developed signs and symptoms of bowel ischemia. The patient underwent successful retrograde open superior mesenteric artery stenting with resolution of her symptoms. Although retrograde open mesenteric artery stenting (ROMS) has been primarily shown to be effective in acute mesenteric ischemia, this case demonstrates that ROMS can be used as a salvage option for shuttering during endovascular procedures.
Improvement in Emotion Regulation While Detained Predicts Lower Juvenile Recidivism
Authors: Docherty Meagan , Lieman Andrew , Gordon Brandon Lee
Published: December 2021

The goal of the current study was to investigate the relationships between observer-rated skills related to emotional and cognitive regulation post-admission and pre-release in a secure facility and official records of juvenile felony recidivism up to 1 year after release. Data came from a sample of 599 youth in a residential facility in Washington state (84% male; 38% White). Latent change score models indicated that both initial level of emotional regulation skills and improvement in emotion regulation skills while incarcerated were significantly related to lower recidivism. This pattern of findings remained when controlling for length of stay, among other covariates. Follow-up analyses indicated that the results for emotion regulation skills might be driven primarily by monitoring internal and external triggers. Additional research should investigate the connection between emotion regulation skills and juvenile recidivism, with a special focus on trigger monitoring and how to improve those skills.

Authors: Mantilla Daniel , Ferreira-Prada Carlos A , Galvis Melquisedec , Vargas Oliverio , Valenzuela-Santos Carolina , Canci Piergiorgio , Ochoa Miguel , Nicoud Franck , Costalat Vincent
Published: December 2021

Objectives

This study evaluated the clinical impact of the Sim&Size® simulation software on the endovascular treatment with flow-diverter stents of patients with unruptured saccular intracranial aneurysms.

Methods

This monocentric retrospective study evaluated a cohort of patients treated with flow-divert stents between June 1, 2014, and December 31, 2019, for cerebral aneurysms. Patients belonged to two groups, patients treated with and without the Sim&Size® simulation software. Univariate, bivariate, and multivariate analyses were used to evaluate the clinical impact of simulation software.

Results

Out of the 73 interventions involving 68 patients analyzed by the study, 76.7% were simulated using the Sim&Size® simulation software, and 23.3% were not. Patients treated with the simulation software had shorter stent lengths (16.00 mm vs. 20.00 mm p-value = 0.001) and surgical time (100.00 min vs. 118.00 min p-value = 0.496). Also, fewer of them required more than one stent (3.6% vs. 17.6% p-value = 0.079). Three patients belonging to the non-stimulated group presented hemorrhagic complications.

Conclusions

Using the Sim&Size® simulation software for the endovascular treatment of intracranial aneurysms with pipeline flow-diverter stents reduces the stent length.
Parasite egg recognition based on multicomponent cues by green-backed tits (Parus monticolus)
Authors: Ye Ping , Cai Yan , Bi Jianli , Yao Xiaogang , Li Guangrong , Yang Canchao
Published: December 2021

Egg recognition and rejection is a common and effective anti-parasitism adaptation in bird hosts. Hosts reject alien eggs using recognition signals such as egg ground color and maculation. Green-backed tits ( Parus monticolus) have a highly developed capability for recognizing parasite eggs, but the cues used for egg recognition are unclear. We combined avian visual perceptual modeling and field experiments to explore the effects of egg ground color and maculation on the recognition of parasite eggs. P. monticolus uses a multi-cue with possible hierarchical mechanism for egg recognition. The mechanism of egg recognition in P. monticolus appears to be a specific adaptation to the phenotypes of eggs laid by local brood parasites.
Long-Term Outcomes Following Manipulation Under Anaesthetic for Patients with Primary and Secondary Frozen Shoulder
Authors: Fairclough Anna , Waters Christopher , Davies Thomas , Dacombe Peter , Woods David
Published: December 2021

Background

Frozen Shoulder (FS) is a common, debilitating condition for which manipulation under anaesthetic (MUA) is a non-invasive and effective treatment option. Current literature evaluates short to medium-term outcomes, but there is a paucity of long-term (>10 years) studies. Knowledge of long-term outcomes is also needed to evaluate whether FS or its treatment pre-disposes to other shoulder pathology in the long-term.

Methods

A retrospective analysis of 398 shoulders undergoing MUA for FS between Jan 1999 and Jan 2010; 240 complete datasets were obtained. Outcomes were Oxford Shoulder Score (OSS), recurrence and development of other shoulder pathology (arthritis or rotator cuff tear).

Results

At long-term follow-up (mean 13.2 years), 71.3% had no symptoms (OSS 48), 16.6% had minor symptoms (OSS 42–47) and 12.1% had significant symptoms (OSS < 42). There were 4/240 (1.7%) self-reported recurrences > 5 years after initial MUA and 2/240 (0.8%) repeat MUAs. In the long-term 6.7% developed rotator cuff pathology and 3.8% shoulder OA.

Discussion

This study suggests that long-term outcome after MUA for FS is favourable. Late recurrence of FS is uncommon and the development of OA or rotator cuff pathology is no greater than that of the general population.
Amputation as a First Treatment is Highly Associated With Late Presentation: An Underestimated Modifiable Major Risk Factor for Diabetic Foot Ulcer
Authors: Yammine Kaissar , Akiki Sandra , Assi Chahine , Hayek, MD Fady
Published: December 2021

Purpose

Several risk factors for lower extremity amputation in diabetic patients have been identified; however, late presentation has been poorly investigated. Very few studies looked at the impact of such risk factor. As none has investigated the link between admission to amputation and late presentation in this population, we investigated such association.

Methods

The study is a retrospective comparative cohort of continuous series of patients admitted for amputation related to diabetic foot ulcer (DFU) as a first treatment. A late presentation was defined as a period of 3 weeks or more from the onset of the ulcer.

Results

Forty-six patients admitted for amputation and all wounds were infected and located on the plantar forefoot in 32 cases (69.5%), on the toes in 10 cases (21.7%), and in the heel area in 4 cases (8.8%). The mean duration to admission was 5.2 ±1.8 weeks (range 4-10 weeks). Late presentation was recorded in 42 (91.3%) patients.

Conclusion

This study demonstrates that amputation due to DFU is highly associated with late presentation. Educational campaigns targeting patient and first-line health care providers and highlighting the urgency of diabetic ulcers are needed to impact this major modifiable risk factor.

Mediatization and Doping: Investigating the Interplay in News Framing of Rider/Doping Suspicion During the Tour de France
Authors: Stanley Leah
Published: December 2021

Mediatization theory has been used to describe the development of the Tour de France, from its inception as an event created by a newspaper to sell newspapers to the global spectacle it has become. Yet, perhaps the Tour’s most infamous aspect, its historical reputation for doping, is yet to be explored through the lens of mediatization, as both a media and a social issue. Furthermore, that sport media scholars allude to a need for better understanding of media coverage of doping beyond headline-capturing doping scandals, establishes a precedent for the examination and comparison of newspaper framing of Lance Armstrong (2004) and Chris Froome (2017). To do so, this research operationalizes mediatization theory in combination with framing theory to investigate news framing of rider/doping suspicion grounded in the historical context of the event, revealing the interplay between framing of rider/doping suspicion and event mediatization processes.
Toward comparative polycentricity scores: Assessing variations in regional delineation and subcenter identification
Authors: Thomas Ryan , Schmidt Stephan , Siedentop Stefan
Published: December 2021

Urban spatial structure is increasingly characterized by polycentricity, the presence of multiple interconnected centers of similar size. Polycentricity indicators, which influence research and policies related to urban development, rely on three phases of analysis: (a) delineating regions, (b) identifying subcenters within these regions, and (c) operationalizing polycentricity; and each phase contains decision points for analysts. This paper argues that polycentricity methodologies should be thought of in terms of pathways, then systematically applies 15 such pathways to the case of German regional polycentricity and compares the results. Findings suggest that questions of polycentricity are more robustly measured by comparing across multiple regional delineation methods and selection of subcenters, then looking for signs of agreement or disagreement. When possible, constructing regions from larger areas through bottom-up methods tends to avoid the biases of administratively defined regions. When this is not possible, statistical approaches to subcenter identification can serve as a check to avoid forced selection of subcenters in poorly defined regions.
Sonographic Prenatal Diagnosis of Ectrodactyly: A Case Study
Authors: Bailess Gretchen
Published: December 2021

Ectrodactyly, also known as split hand/split foot malformation, is a rare congenital disease defined as the absence or underdevelopment of the central digits with a median cleft of the hand or foot. It can be an isolated sonographic finding or associated with a syndrome. This case study describes isolated left-handed ectrodactyly diagnosed sonographically at 20 weeks gestation, during a routine anatomy sonogram. The patient had no family history of this condition, which demonstrates the importance of sonography for early diagnosis, counseling, and genetic testing options.
Cognitive Distractions During Sonographic Procedures: Reducing Noise-Based and Light-Based Interruptions in Hospital Rooms
Authors: Stigall-Weikle Nicole , Evans Kevin D. , Patterson Emily S.
Published: December 2021

Sonographers experience a high cognitive load in hospital-based care. High ambient noise and frequent noise-based interruptions include knocking on the room door, questions from others in the room or through communication technology, alarms, alerts from personal devices, and carts and people passing in the hallway. In addition, other providers turning on the overhead light is distracting for exams that need to be conducted in reduced lighting conditions. This article suggests strategies to improve working conditions for sonographers conducting exams on a patient in the hospital room. Our strategies emerge from human factors methods and principles, which derive from communication principles and theory. These strategies are organized by reducing noise-based and light-based interruptions in the hospital room and hallway, primarily through changes to the built environment and communication technology settings and reducing the use of speech during cognitively challenging time periods through training. Most of the strategies are low-cost and can be implemented within the current built environment and communication technology infrastructure. We anticipate that these strategies could enhance patient outcomes, increase patient satisfaction, improve sonographers’ job satisfaction, protect provider health, and increase procedural efficiency.

Background

SPX-containing proteins have been known as key players in phosphate signaling and homeostasis. In Arabidopsis and rice, functions of some SPXs have been characterized, but little is known about their function in other plants, especially in the legumes.

Results

We analyzed SPX gene family evolution in legumes and in a number of key species from algae to angiosperms. We found that SPX harboring proteins showed fluctuations in domain fusions from algae to the angiosperms with, finally, four classes appearing and being retained in the land plants. Despite these fluctuations, Lysine Surface Cluster (KSC), and the third residue of Phosphate Binding Sites (PBS) showed complete conservation in almost all of SPXs except few proteins in Selaginella moellendorffii and Papaver sumniferum, suggesting they might have different ligand preferences. In addition, we found that the WGD/segmentally or dispersed duplication types were the most frequent contributors to the SPX expansion, and that there is a positive correlation between the amount of WGD contribution to the SPX expansion in individual species and its number of EXS genes. We could also reveal that except SPX class genes, other classes lost the collinearity relationships among Arabidopsis and legume genomes. The sub- or neo-functionalization of the duplicated genes in the legumes makes it difficult to find the functional orthologous genes. Therefore, we used two different methods to identify functional orthologs in soybean and Medicago. High variance in the dynamic and spatial expression pattern of GmSPXs proved the new or sub-functionalization in the paralogs.

Conclusion

This comprehensive analysis revealed how SPX gene family evolved from algae to legumes and also discovered several new domains fused to SPX domain in algae. In addition, we hypothesized that there different phosphate sensing mechanisms might occur in S. moellendorffii and P. sumniferum. Finally, we predicted putative functional orthologs of AtSPXs in the legumes, especially, orthologs of AtPHO1, involved in long-distance Pi transportation. These findings help to understand evolution of phosphate signaling and might underpin development of new legume varieties with improved phosphate use efficiency.
Barriers and attitudes towards cervical cancer screening in primary healthcare in Poland - doctors’ perspective

Published: December 2021

Background

Healthcare systems have adopted different strategies to reduce the burden of cervical cancer. In Poland, a population-based screening program was implemented in 2006, leading to a downward trend in cervical cancer burden. However, screening rates are still low in relation to other EU member states. In Poland, Pap smears are mainly performed by gynecologists rather than Primary Health Care (PHC) physicians. Little is known about the experiences and attitudes of the latter regarding cervical cancer screening in a PHC setting.

Methods

A cross-sectional questionnaire-based survey was carried out among 43 PHC physicians from the Malopolska region in Poland. Barriers and attitudes towards cytology in a PHC setting were evaluated.

Results

Approximately 35% of surveyed physicians reported having experience in performing cytology. Almost 75% of PHC physicians lacked the necessary equipment in their office to perform the screening. None of the studied physicians performed Pap smears in their office at the time. The reasons included: shortage of competence (78.57%) and time (69.05%), the perception of Pap smears as a task for gynecologists (69.05%), the lack of financial incentives (61.90%), and the belief that their patients would be unwilling to undergo the test in their PHC physician’s office (33.33%). More than three quarters (76.74%) declared they would be ready to perform Pap smears if the tests were additionally paid. No significant associations between PHC physicians’ characteristics and their willingness to perform cytology screening were found.

Conclusion

The primary barrier to perform Pap smears by PHC physicians does not lie in their personal reluctance but in the organization of the healthcare system. Provision of required training and proper funding allocation can likely improve the screening rate of cervical cancer in Poland.
