Background

The mechanisms linking menopausal age and heart failure (HF) incidence are controversial. We investigated for heterogeneity by obesity on the relationship between menopausal age and HF incidence.

Methods and Results

Using postmenopausal women who attended the Atherosclerosis Risk in Communities Study Visit 4, we estimated hazard ratios of incident HF associated with menopausal age using Cox proportional hazards models, testing for effect modification by obesity and adjusting for HF risk factors. Women were categorized by menopausal age: <45 years, 45 to 49 years, 50 to 54 years, and ≥55 years. Among 4441 postmenopausal women, aged 63.5±5.5 years, there were 903 incident HF events over a mean follow‐up of 16.5 years. The attributable risk of generalized and central obesity for HF incidence was greatest among women who experienced menopause at age ≥55 years: 11.09/1000 person‐years and 7.38/1000 person‐years, respectively. There were significant interactions of menopausal age with body mass index and waist circumference for HF incidence,
P
interaction
0.02 and 0.001, respectively. The hazard ratios of incident HF for a SD increase in body mass index was elevated in women with menopausal age <45 years [1.39 (1.05–1.84)]; 45–49 years [1.33, (1.06–1.67)]; and ≥55 years [2.02, (1.41–2.89)]. The hazard ratio of incident HF for a SD increase in waist circumference was elevated only in women with menopausal age ≥55 years [2.93, (1.85–4.65)].

Conclusions

As obesity worsened, the risk of developing HF became significantly greater when compared with women with lower body mass index and waist circumference, particularly among those who had experienced menopause at age ≥55 years.
A Muslim-Christian Heterarchy in 12th-Century Cairo
Authors: Beinhauer-Köhler Bärbel
Published: April 2022

In 1103 C.E. the newly elected Coptic patriarch Abā Maqāra rode in a procession to the residence of the Fatimid vizier al-Afḍal in al-Qāhira, where a ceremonial reception took place. Both men represented entangled political groups of interest, and this moment can be taken as an equilibrium of power between the city’s Muslims and Christians. At least, the main document about the event evokes this impression: being part of the official historiography of the Egyptian Coptic Orthodox Church, this text is an element of political negotiations and semantics too. Carole Crumley’s approach of a dynamic interplay between hierarchy and heterarchy can be a tool for better understanding this historic moment and for illuminating its complex sociocultural and spatial constructions. On the one hand, the Christians’ status was shaped by the strict ranking of the ḏimma-law. On the other hand, Cairo was like other urban settlements under Muslim rule: at least in some aspects an heir of the antique polis representing several groups of interest.
Emotional Labour in Publishing
Authors: Shaw Sarah
Published: April 2022

Emotional labour has been widely recognized in a variety of industries, but not yet in publishing. By examining 126 survey responses from current or former publishing employees, this study identifies the primary forms of emotional labour present in the publishing industry, and how these vary between employees. Also examined is the extent to which industry leaders recognize the emotional labour performed by employees, and the impact that this emotional labour has on the latter. The survey responses demonstrate a high prevalence of emotional labour in the publishing industry and that this work is largely unrecognized and sometimes entirely dismissed. Emotional labour also has a generally negative impact on employees, particularly working-class and black, Asian, and minority ethnic (BAME) employees, which contributes to low diversity in the industry. I conclude with recommendations for further research and for industry change to reduce emotional labour, improve employee welfare, and facilitate increased retention of working-class and BAME employees.

Authors: Karataş Kasım , Arpaci Ibrahim , Yildirim Yusuf
Published: April 2022

This study aimed to predict the culturally responsive teacher roles based on cultural intelligence and self-efficacy using machine learning classification algorithms. The research group consists of 415 teachers from different branches. The Bayes classifier (NaiveBayes), logistic-regression (SMO), lazy-classifier (KStar), meta-classifier (LogitBoost), rule-learner (JRip), and decision-tree (J48) were employed in the assessment of the predictive model. The results indicated that JRip rule-learner had a better performance than other classifiers in predicting the culturally responsive teachers based on six attributes used in the study. The JRip rule-learner classified the culturally responsive teachers as low, medium, or high with an accuracy of 99.76% (CCI: 414/415) [Kappa statistic: 0.996, Mean Absolute Error (MAE): 0.003, Root Mean Square Error (RMSE): 0.043, Relative Absolute Error (RAE): 0.663, Relative Squared Error (RRSE): 9.244]. The results indicated that all classifiers had an acceptable performance but JRip rule-learner had a better performance than the other classifiers in predicting the culturally responsive teachers.
Building Brand Assets: The Role of Trademark Rights
Authors: Krasnikov Alexander , Jayachandran Satish
Published: April 2022

Trademarks play an important role in protecting intangible brand assets. However, the impact of trademark rights on brand assets has received little attention in the literature. The authors examine the impact of trademark rights on brand assets from the perspective of appropriability—that is, the firm’s ability to benefit from innovation and creativity. To ensure causal identification, they use a natural experimental context in which U.S. Supreme Court decisions on trademark rights provide an exogenous variation in strength of trademark rights. Using a database of trademarks registered in the United States and a difference-in-difference estimation approach, the authors show that, overall, trademark applications and applications to register in other categories increase when trademark rights are strengthened and decrease when trademark rights are weakened. However, trademarking responses of brands to a change in property rights are muted for design trademarks and amplified when a firm has multiple brands. The authors discuss the theoretical, substantive, and managerial implications of the findings and provide guidance for further research.
An Operational Definition of End-of-Life Healthcare: A Complex and Subjective Construct
Authors: Mauck Erin E.
Published: April 2022

Comprehensively defining end-of-life healthcare is a challenge due to the diverse areas of healthcare involved, the various stakeholders, and the range of patient options. This qualitative study examined many areas of end-of-life healthcare including quality, areas for improvement, and healthcare policy in Tennessee, in which the definition of end-of-life healthcare was a focus. Data were collected using semi-structured interviews with 19 participants who included end-of-life healthcare experts and Tennessee legislators. Through this research an operational definition of end-of-life healthcare, encompassing five concepts, was developed. Concepts include: a diagnosis, a timeframe, type of care, location of care, and planning for the future. When considered together, they are the embodiment of what end-of-life healthcare encompasses. Not in a one-fits-all definition, but individually tailored. An understanding of what end-of-life healthcare denotes is essential to maintaining open communication, high quality standards of care, and the protection of patient autonomy.
Présence, Visage, Lumière - L’assemblée Liturgique Comme Icône
Authors: Sauvé Julien
Published: April 2022

Les espaces liturgiques aménagés par Jean-Marie Duthilleul peuvent être qualifiés d’aniconiques. Pourtant, une étude approfondie de la théologie qui les sous-tend fait prendre conscience que Duthilleul ne rejette pas la question de l’image dans ses espaces, mais la déplace. En effet, l’attention qu’il porte à la forme de l’assemblée, à la disposition des participants dans la liturgie, aux visages de ceux-ci et à la lumière qui les éclaire, manifeste le souci de prendre au sérieux la présence du Christ au milieu de son peuple rassemblé pour prier et chanter les psaumes (cf. Sacrosanctum Concilium 7). Or, ces notions de présence, visage et lumière relèvent précisément de la démarche de l’iconographe. Il est donc possible de considérer que Duthilleul envisage l’assemblée liturgique comme une icône.
Misophonia: An Underrecognized Disease in Pediatric Patients
Authors: Swonke Megan L. , Neve Luis , Rossi Nicholas A. , McKinnon Brian , Daram Shiva , Pine Harold S.
Published: April 2022

Misophonia is a chronic condition in which patients experience a strong negative, emotional, or psychologic reaction to specific sounds. These sounds cause the individual to have a sudden, uncontrolled, and disproportionate negative reaction affecting their daily activities. The literature describes several cases of misophonia in the adult population; however, only 2 pediatric case studies are reported. Herein, we present 2 additional cases. An exaggerated response to an auditory stimulus is observed in other disorders such as tinnitus, hyperacusis, migraines, and many psychiatric disorders. Sound aversion has a broad differential diagnosis and may require visits to numerous specialists, placing strain on the patient and the healthcare system. Furthermore, misophonia is underdiagnosed in the pediatric population as it requires self-reporting of symptoms. The pathophysiology, prevalence, and treatment of misophonia continue to be relatively unknown. We attempt to highlight this rarely reported pediatric diagnosis and elaborate on its clinical presentation to increase awareness among otolaryngologists.
Faults and Faultlines: The Effects of Board Faultlines on CEO Dismissal
Authors: Shin Taekjin , You Jihae
Published: April 2022

On the basis of the view that the board’s evaluation of the CEO is determined by the board decision-making as a group, we adopt the faultline approach to analyze group dynamics in the board. Faultlines can split a board based on the alignment of multiple attributes of individual directors and potentially create subgroups within the board. In this study, we argue that different types of faultlines have distinct effects on board decision-making. Specifically, we predict that demographic faultlines can increase conflicts among directors, hampering the board’s ability to decide on CEO dismissal when firm performance is below the aspiration level. On the other hand, information-based faultlines can facilitate exchange of diverse knowledge and elaboration of alternative perspectives, which can improve the board’s ability to dismiss a CEO when firm performance is below the aspiration level. Our analysis of S&P 500 boards supports our prediction that board faultlines based on demographic attributes of directors significantly reduce the board’s ability to fire the CEO when firm performance is below the aspiration level, whereas faultlines based on information-related attributes magnify the board’s ability to dismiss a poor-performing CEO. By demonstrating different effects of faultlines based on heterogenous types of director attributes, this study contributes to the board faultline literature. We also contribute to CEO dismissal research by showing how group dynamics of boards moderates the relationship between firm performance and CEO dismissal.
A Foucauldian Analysis of the Romanian School of Gymnastics as a Superpower Between 1976-1981: What Securitatea Knew About Bela Karolyi’s Method
Authors: Petracovschi Simona
Published: April 2022

During the Cold War, the Romanian school of gymnastics represented a superpower in the world of WAG and became a part of Romania’s international politics strategy. This ascension started under the supervision of Bela Karolyi, the coach of the Romanian team between 1972 −1981. Bela Karolyi represented the type of coach who used tactics to produce performance. Forced by Securitatea surveillance, the political police of the communist government, Bela Karolyi had to constantly adapt the technologies of power to have the best tactics to win. By using the hierarchical power of communist government against the Romanian Gymnastics Federation, Bela Karolyi was able to build his tactics until the moment it ran against the government strategy. Forced to defect to the other side of the Iron Curtain, Bela Karolyi continued to improve his technologies of power and tactics that transformed the United States WAG team in a superpower.

Authors: Wu Yong , Huang Bihong , Zhang Weichen , Farhan Khawlah Ali Ahmed , Ge Siyao , Wang Mengjing , Zhang Qian , Zhang Minmin
Published: April 2022

Objective

To compare the all-cause mortality of aged and younger patients undergoing maintenance hemodialysis (MHD) over the long or short term, and to identify independent risk factors.

Methods

We performed a retrospective cohort study using the medical records of 181 patients undergoing MHD. We compared the clinical characteristics and laboratory data of survivors and participants who died, according to their age and the duration of MHD. Binary stepwise logistic regression was used to identify independent risk factors for all-cause mortality.

Results

Cardiovascular and cerebrovascular diseases were the principal causes of mortality. The number of aged participants with hypertensive nephropathy as their primary kidney disease was significantly higher than the number of younger participants. The proportion with chronic glomerulonephritis was significantly higher for participants undergoing long-term MHD. Logistic regression analysis revealed that low body mass index, single-pool Kt/V, serum albumin, platelet count, and total iron-binding capacity; and high intact parathyroid hormone and N terminal pro B type natriuretic peptide were independent risk factors for all-cause mortality.

Conclusions

Aged patients are more susceptible to hypertensive nephropathy than younger patients. In addition, the survival of patients with chronic glomerulonephritis undergoing MHD is superior to that of those with hypertensive or diabetic nephropathy.

‘A Man Who Has Both Arms’: Arthur Griffith, the Economy and the Anglo-Irish Treaty Agreement 1921
Authors: Kenny Colum
Published: April 2022

Arthur Griffith founded Sinn Féin. From 1899 onwards, through detailed articles in his weekly papers and otherwise, he strongly advocated the economic development of Ireland and the adoption of qualified protectionism to achieve it. As minister for foreign affairs in the revolutionary government of Ireland in 1921, he chaired the Irish delegation that negotiated with Lloyd George's government articles of agreement for an Anglo-Irish Treaty. In January 1922 he was elected president of Dáil Éireann, the revolutionary Irish parliament, but died suddenly in August 1922 before the new Irish Free State formally came into existence. This essay underlines the importance that he attached to economic affairs, not least in making fiscal autonomy a central ambition of his negotiations with the British. The author concludes that Griffith was far-sighted, and calls for a discrete and empathetic study of his economic ideas.
Study of the Potential Effects of Gate-Hold Strategies on Arrival and Departure Operations at Charlotte Douglas International Airport
Authors: Smith Laurence Douglas , Bilir Canser
Published: April 2022

We employed discrete-event simulation with embedded multivariate statistical models for time and situation-dependent parameters to study the potential impact of regulating the release of planes from their terminal gates in peak periods to reduce congestion on ramps and taxiways at Charlotte Douglas International Airport, a major U.S. hub for of the world’s largest airline, American Airlines. Gate-holding strategies are one of several operational strategies to reduce aviation’s carbon footprint. They have been shown to reduce fuel consumption, air pollution, and greenhouse gas emissions, but past studies have concentrated on taxi times and fuel consumption of outbound aircraft without considering the potential disruptions on inbound traffic, which may be blocked from reaching their intended gates. We verified that reductions in outbound taxi times could be achieved without delaying the times when planes lifted off for departure but, depending on the gate-hold rules employed and the intensity of flight operations, more delays and gate changes occurred for arriving aircraft. Our models allow intensive examination of the tradeoffs involved in improving system performance with various strategies.
Evaluation of Microwave Heating for Potential Applications in Hot In-Place Recycling of Asphalt Pavement
Authors: Chen Xiao , Wang Hao , Jiang Baiyu , Venkiteela Giri
Published: April 2022

Hot in-place recycling (HIR) has been adopted in pavement engineering because of its low financial cost and lower consumption of nonrenewable material. At present, infrared heating is the most common heating method in HIR, while microwave heating has been proposed as an alternative to it recently. This study investigated and compared the characteristics of microwave and infrared heating by laboratory experiments and numerical modeling. Laboratory tests were first conducted to determine thermal parameters of asphalt mixture and calibrate electromagnetic parameters based on numerical simulation. Two numerical models of microwave and infrared heating under field conditions were further established for analyzing the heating characteristics, including the temperature distribution, heat transfer rate, and energy consumption. The results show that infrared heating can only heat the pavement at shallow depth, while microwave heating can heat the pavement surface and the materials at greater depths to high temperatures. An increase in power was found to enhance the efficiency of microwave heating but to maybe reduce that of infrared heating. Moreover, under the same power, microwave heating needs much less time and energy than infrared heating to reach the same temperature. Microwave heating shows great potential to be applied for HIR of asphalt pavement with the increased recycling depth.
Risk of Graft Rupture After Adding a Lateral Extra-articular Procedure at the Time of ACL Reconstruction: A Retrospective Comparative Study of Elite Alpine Skiers From the French National Team
Authors: Guy Sylvain , Fayard Jean-Marie , Saithna Adnan , Bahroun Sami , Ferreira Alexandre , Carrozzo Alessandro , De Jesus Stephane , Bulle Stephane , Vieira Thais Dutra , Sonnery-Cottet Bertrand
Published: April 2022

Background:

Elite alpine skiing is associated with a particularly high risk of anterior cruciate ligament (ACL) injuries, including graft ruptures. Despite a considerable focus on prevention, a reduction in injury rates has not been observed since the 1980s.

Purpose:

To determine whether elite alpine skiers undergoing ACL reconstruction (ACLR) with a lateral extra–articular procedure (LEAP) had a lower rate of ACL graft rupture when compared with those who underwent isolated ACLR.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Elite skiers from the French ski team who had undergone ACLR, with or without a LEAP, and had a minimum follow–up of 2 years were identified from the national ski team database. Rates of secondary ACL injury were determined via interrogation of the database, review of medical notes, and a final telemedicine interview. A multivariable analysis using the penalized Cox model was performed to explore the relationship among graft rupture, surgical procedure type, and any potential explanatory variables.

Results:

Among 81 ACLR procedures analyzed, 50 were isolated and 31 were combined with a LEAP, which was performed using modified Lemaire or anterolateral ligament reconstruction. Graft rupture rates were 34.0% in the isolated ACLR group and 6.5% in the ACLR + LEAP group. Multivariable analysis demonstrated that adding a LEAP was associated with a significant reduction in risk of ACL graft rupture when compared with isolated ACLR (hazard ratio [HR], 5.286 [95% CI, 1.068-26.149]; P = .0412). Age (HR, 1.114; P = .1157), sex (HR, 1.573; P = .3743), and ACL graft type (HR, 1.417; P = .5394) were not significant risk factors.

Conclusion:

Combined ACLR and LEAP were associated with a significant reduction in the rate of ACL graft rupture in elite alpine ski athletes. Those treated with isolated ACLR remain at extremely high risk of a second ACL injury.

Authors: Silva-Junior João Silvestre , Niituma Ogata Alberto José , Scarpellini Bruno Correia , Arantes da Cunha Arthur , Trockel Mickey , Demarch Rodrigo Bornhausen
Published: April 2022

Purpose

The questionnaire “Professional Fulfillment Index” (PFI) was validated to assess emotional exhaustion, interpersonal disengagement, and professional achievement among physicians. This study presents the process of cross-cultural adaptation of the PFI to the Brazilian context.

Design

Analytical cross-sectional study carried out between July and October 2020. Settings: For conceptual equivalence, a panel of experts was constituted who conducted analyzes on the translation and back-translation processes from English to Brazilian Portuguese.

Subjects

For the operational equivalence, 432 physicians in the field of Occupational Medicine were invited.

Measures

They answered the PFI in an online platform. Analysis: Both exploratory and confirmatory factor analysis were performed to seek evidence of the hypothesized structure of PFI item responses. Reliability was assessed using three indicators.

Results

The Brazilian version can be considered similar to the original. Most of participants were female (57.6%) and mean age 49.6 years—SD 14.0. The mean time since graduation was 18.5 years—SD 9.67. Most of them had a full-time job (88.0%) and were trained through post-graduation courses 83.8%. The most frequent job task was to perform worker´s clinical evaluations (84.9%). Exploratory and confirmatory analyzes showed the adequacy of the items in measuring the instrument’s construct, with stability for use in other populations and samples.

Conclusion

The PFI was developed to evaluate positive and negative aspects of physicians’ role and performance. The process described in this article was the first cross-cultural adaptation of the questionnaire. The PFI can help in mapping potential risk situations for negative impacts on physicians’ occupational well-being and performance at work, in order to propose interventions that reduce exhaustion and expand professional fulfillment.

Published: April 2022

The present study aims at investigating the properties of copper matrix-based hybrid metal matrix composites (MMCs) reinforced with ZrO2 and Graphite. The MMCs were prepared using stir casting technique. The composite material was developed for its application in thermal management structures. The properties of the prepared MMCs were found to be dependent on the reinforcements content present in the MMCs. ZrO2 and Graphite reinforcements were added (0.5–0.5, 1.0–1.0, 1.5–1.5 and 2.0–2.0 wt %) in the four composite samples prepared via stir casting. Amongst several available techniques, stir casting was chosen to prepare the samples due to its simplicity and economic viability. The phase identification was done by using X-ray diffraction (XRD) and the microstructure was observed using Scanning Electron Microscopy (SEM). No intermediate phase was observed from the XRD results. The reinforcement phase was found to be dispersed in a uniform manner as observed through the SEM micrographs. The density of the samples was found to decrease with an increase in the reinforcements content. The density of the composite sample containing 2 wt. % of each reinforcement was found to be 8.01 g/cm3 which was 10% lesser than pure copper. Hardness of pure copper sample was found to be 35.71 BHN; however, the hardness of composite sample containing 4 wt. % of each of the reinforcements was found to be 70.14 BHN which indicates an increase of around 100%. Wear rate of pure copper and composite sample containing 5 wt. % of each of the reinforcements was found to be 0.3788 mm3/Km and 0.3603 mm3/Km, respectively, at 20 N load. However, the composite samples consisting of 4 wt. % of each of the reinforcements exhibited wear rate of 0.3001 mm3/Km which was 20% lesser than that of pure copper at the same load. The compressive strength of composite sample containing 2.0 wt. % ZrO2 and graphite was found to be 674.57 MPa which was around 1.25% higher than the composite sample containing 0.5 wt. % reinforcements. The specific heat of the samples was found to increase marginally with an increase in reinforcement content. It is expected that the hybrid composites developed will be suitable for use in structural applications pertaining to thermal management.
ICT, carbon emissions, climate change, and energy demand nexus: The potential benefit of digitalization in Taiwan
Authors: Adha Rishan , Hong Cheng-Yih , Agrawal Somya , Li Li-Hua
Published: April 2022

The global rise in energy consumption makes managing energy demands a priority. Here, the potential of Information and Communication Technology (ICT) in controlling energy consumption is still debated. Within this context, the main objective of the current study is to measure the impact of ICT, its potential benefit, and environmental factors on household electricity demand in Taiwan. A panel of data from 20 cities in Taiwan was collected during the period 2004–2018. We adopted PMG estimation and applied the DH-causality test for analysis. The estimation results show that ICT, carbon emissions, and climate change will drive household electricity demand in Taiwan in the long term. However, ICT has a higher potential to reduce electricity demand in the short-term period. In addition, the results of the causality test reveal a two-way interrelationship between ICT and electricity demand. Our study also found that climate change indirectly affects the use of electricity through household appliances. We also presented several policy implications at the end of this paper.
‘Zonked the hell out’: Climate change and heat stress at work
Authors: Humphrys Elizabeth , Goodman James , Newman Freya
Published: April 2022

Climate change is most directly felt by people who cannot escape its impacts, including workers whose source of livelihood may put them directly at risk from high heat. Research on these impacts for Australian workers, especially the sociopolitical determinants of effective workplace heat management, remains limited. This article presents findings from a national research project that investigated these issues in collaboration with the Australia-based United Workers Union. It reports on the experiences of members exposed to high heat, explores how they address heat stress and how they relate this to climate change. The article expands understanding of the impacts of workplace heat, especially for indoor workers and those in lower paid jobs, through a focus on how workers articulate their experiences and understand and exercise their agency at work.

Published: April 2022

Objective

To develop and validate a generalized prediction model that can classify epidermal growth factor receptor (EGFR) mutation status in non–small cell lung cancer patients.

Methods

A total of 346 patients (296 in the training cohort and 50 in the validation cohort) from four centers were included in this retrospective study. First, 1085 features were extracted using IBEX from the computed tomography images. The features were screened using the intraclass correlation coefficient, hypothesis tests and least absolute shrinkage and selection operator. Logistic regression (LR), decision tree (DT), random forest (RF), and support vector machine (SVM) were used to build a radiomics model for classification. The models were evaluated using the following metrics: area under the curve (AUC), calibration curve (CAL), decision curve analysis (DCA), concordance index (C-index), and Brier score.

Results

Sixteen features were selected, and models were built using LR, DT, RF, and SVM. In the training cohort, the AUCs was .723, .842, .995, and .883; In the validation cohort, the AUCs were .658, 0567, .88, and .765. RF model with the best AUC, its CAL, C-index (training cohort=.998; validation cohort=.883), and Brier score (training cohort=.007; validation cohort=0.137) showed a satisfactory predictive accuracy; DCA indicated that the RF model has better clinical application value.

Conclusion

Machine learning models based on computed tomography images can be used to evaluate EGFR status in patients with non–small cell lung cancer, and the RF model outperformed LR, DT, and SVM.
Improved low-frequency sound absorption of porous silicone rubber resonance sheet with periodic cavities
Authors: Peng Longgui , Zhao Pu , Cheng Huanquan , He Qirui , Du Lifei
Published: April 2022

Since the development of advanced sound absorption material is highly critical in noise control applications, anechoic coatings, and acoustic metamaterials, both fabrication technology and structure design are significant in the achievement of broadband and strong absorption performance in the low sound frequency range. In this work, the silicone rubber resonance absorption sheet with periodic cavities is prepared via inserting cylindrical steel strips with different diameters into the non-vulcanized colloid. Effects of size and arrangement of cavities on the sound absorption properties, as well as the corresponding mechanical properties, are investigated and discussed. Results indicate that periodic pattern designs could further improve the low-frequency sound absorption performance of silicone rubber foams, and increasing the cavity diameter could significantly improve the sound absorption efficiency of the prepared samples in the middle- and low-frequency range from 125 to 2000 Hz. Particularly, increasing the number of the layered cavities could also improve the sound absorption efficiency. The consumption of sound energy in the prepared silicone rubber resonance sheet is discussed, which could be attributed to the synergistic effect in different spatial scales.

Authors: Riegraf David , Öchsner Andreas , Greuling Steffen , Speckle Mattias-Manuel , Müller-Lohmeier Klaus
Published: April 2022

Customer expectations are increasing, especially with regard to the individualization of products, in which additive manufacturing is described as a disruptive technology. With a view to using the technology in a series application, extensive knowledge of the starting material, the powder, is necessary. In this article, AlSi10Mg in powder form (grain size range: 15–70 µm), which is used for the selective laser melting process, is analysed on the basis of various investigations. A distinction is made from other researchers, as a total of six powders of the same specification but from different manufacturers were used. An investigation of the relative humidity of the powders in the as-delivered condition was carried out using a moisture meter. It could be shown that the moisture lies between 5% and 15% and that the moisture can be reduced by about half by using dry bags. A qualitative examination with a scanning electron microscopy showed that the morphology and size distribution differ. Not only partially round, but also very misshapen particles and particles with and without adhesions are present. The flowability was determined with a calibrated Hall flowmeter. It was found that a lower proportion of fine particles in the powder lead to a more uniform flowability. In the investigation, a distinction was made between powder in the as-received state and dried powder. The particle size distribution was determined with a laser diffraction method and evaluated according to the Mie theory. To be able to carry out porosity analyses on the basis of micrographs, test cubes with the dimensions (10 × 10 × 10 mm3) were used. The parameters scanning speed (400–600 mm/s), hatch spacing (0.19–0.29 mm), and laser power (220–320 W) were varied. The results vary between 0.12% and 5.46% porosity. To combine the results, a pairwise comparison and a use-value analysis were carried out. Overall, the differences in the powders of the different manufacturers were found to be small, so that a recommendation was made for the most economical powder.
Integrated interval Mahalanobis classification system for the quality classification of turbine blades based on vibrational data incorporating measurement uncertainty

Published: April 2022

Measurements are not exactly accurate, and measurement errors could lead to a biased trained classifier, and finally to a wrong classification of the parts. This paper extends the recently proposed (Integrated) Mahalanobis Classification System with the concept of Interval Mahalanobis distance (IMD) in order to account for measurement uncertainty. This novel Integrated Interval Mahalanobis Classification System (IIMCS) is applied to an experimental case study of complex shaped metallic turbine blades with various damage types. The turbine blades have been vibrationally tested in a wide frequency range. The IIMCS selects a subset of optimal features that contribute the most to the system under the framework of Binary Particle Swarm Optimization, and determines the optimal decision threshold based on Particle Swarm Optimizer. A Monte Carlo method (MCM) is implemented to account for measurement uncertainty, and as such yields an indicator of reliability, implying the confidence level of the classification results. The obtained results illustrate a high performance of the IIMCS for classifying turbine blades based on vibrational response data with measurement uncertainty.
Upskirting: A Systematic Literature Review
Authors: Lewis Ruth , Anitha Sundari
Published: April 2022

Upskirting’ – the non-consensual taking and/or dissemination of intimate images taken surreptitiously up a skirt – is a relatively new addition to the repertoire of men’s violence against women and girls. Recently, it has received considerable media and public attention in many countries and some academic scrutiny. This systematic review explicates how scholars construct upskirting as a matter for academic inquiry and a social problem that requires remedy. Four research sub-questions address how scholarship constructs: the problem of upskirting; perpetrators of upskirting; victims of upskirting, and remedies. Five bibliographical databases were searched, yielding 26 sources that met the inclusion criteria. Most of the studies (16) and most of the earlier work are from the discipline of Law. Other studies come from a combination of Criminology, Media Studies, Cultural Studies, Psychology, Social Work, Sociology, and Computing. The predominance of legal scholarship has created a framing of upskirting which constructs it as an individual sexual act, for purposes of sexual gratification, as gender-neutral, as the act of aberrant individuals, and scrutinises the act of taking the photograph. By contrast, scholarship from other disciplines is more likely to locate upskirting as highly gendered behaviour in the context of gendered relations of power, and of violence against women and girls, and to consider both the act of taking the photograph and its dissemination online. We argue that future research ought to: approach upskirting as a form of violence against women and girls; be empirical and intersectional, and engage with victims and perpetrators.

Purpose:

To compare the long-term outcomes of the most widely used third-generation stent grafts, the Endurant and Excluder stent grafts, in Japanese patients using a multicenter registry.

Materials and Methods:

A retrospective analysis of endovascular aneurysm repairs for abdominal aortic and iliac artery aneurysms using either the Endurant or the Excluder stent grafts from January 2012 to July 2019 at 10 Japanese hospitals was performed.

Results:

A total of 332 and 378 repairs using the Endurant and Excluder stent grafts, respectively, were analyzed. Although the patients’ characteristics were generally similar in the two groups, the Endurant group exhibited significantly shorter (Endurant: 31.5±18.6 mm, Excluder: 37.4±21.0 mm; p<0.001), larger (Endurant: 22.4±4.2 mm, Excluder: 21.7±3.8 mm; p=0.029), and more reversed tapered (Endurant: 12.1%, Excluder: 5.8%; p=0.003) proximal necks. The incidence of instructions for use (IFU) violations was similar between the two groups (Endurant: 59.0%, Excluder: 54.5%; p=0.223). However, the Endurant group had significantly more proximal neck-related IFU violations (54.1% and 46.3%, respectively; p=0.039), more access-related IFU violations (8.1% and 4.0%, respectively; p=0.019), and fewer bilateral hypogastric artery embolizations (5.1% and 9.3%, respectively; p=0.035) compared with the Excluder group. The incidence of intraoperative (Endurant: 3.6%, Excluder: 3.7%; p=0.950) and perioperative complications (Endurant: 3.6%, Excluder: 3.4%, p=0.899) was equivalent in the two groups. However, there was a significantly higher incidence of postoperative type II endoleaks in the Excluder group (Endurant: 28%, Excluder: 46.0%, p<0.001). Aneurysm sac regression was more frequent in the Endurant group (Endurant: 40.7%, Excluder: 31.7%, p=0.013). The Endurant group also had significantly higher rates of sac increase (Endurant: 13.0%, Excluder: 7.7%, p=0.020). Kaplan-Meier curve and log-rank analyses revealed no statistical differences in late complications (p=0.868) and overall survival (p=0.926).

Conclusions:

There were no statistically significant differences between the Endurant and the Excluder stent grafts in terms of intraoperative, perioperative, and late complication rates; however, the anatomical characteristics of the patients were significantly different.
Salvage of an Incomplete Sandwich With a Covered Celiac Trunk and a “Floating” Superior Mesenteric Artery Stent in a Thoracoabdominal Aortic Aneurysm

Published: April 2022

Purpose:

To report a case of a patient with a large thoracoabdominal aortic aneurysm (TAAA) extent V treated with a custom-made fenestrated and branched endovascular repair (F/B-EVAR) after a failed and incomplete attempt of a Sandwich repair technique.

Report:

An 83-year-old patient was referred to our department after a failed attempt at endovascular repair of type V TAAA with a sandwich technique. The celiac trunk was inadvertently covered with the first endograft and a covered long superior mesenteric artery stent was placed and left facing upward inside the aorta. We performed a staged repair, by first catheterizing and stenting the celiac trunk and bringing it under and inside the main aortic endograft. In interval, a F/B-EVAR was performed using a bimodular custom-made device (CMD) with a proximal 2 branch module for the celiac trunk and superior mesenteric artery and distal module with fenestrations for both renal arteries. The intervention was successful, and the follow-up was uneventful at 6 months.

Conclusions:

Re-intervention after failed endovascular attempts of TAAA repair are technically challenging and require advanced endovascular techniques. The ability to construct CMDs allowed to extend repair to our patient which had severe anatomical constraints for other techniques.
Queering the Form: Zine-Making as Disruptive Practice
Authors: Damon Lisa , Kiconco Gloria , Atukunda Charity , Pahl Kate
Published: April 2022

This article is an exploration of the zine as a form of practice that is radical and disruptive. It takes the form of six sections and has its own zine armature. It describes a zine workshop held in Kampala, Uganda, during lockdown, and constitutes a record of that event. The authors argue that zine-making is itself a form that can offer a queering of the status quo and can make authors of us all. It invites the reader into the space of the zine as a form that is both materially grounded and epistemologically challenging.
