Authors: Fischer David , Györgyi Péter 
Published: April 2023

AbstractIn this paper we consider the coupled task scheduling problem with exact delay times on a single machine with the objective of minimizing the total completion time of the jobs. We provide constant-factor approximation algorithms for several variants of this problem that are known to be $$\mathcal{N}\mathcal{P}$$

N
P

-hard, while also proving $$\mathcal{N}\mathcal{P}$$

N
P

-hardness for two variants whose complexity was unknown before. Using these results, together with constant-factor approximations for the makespan objective from the literature, we also introduce the first results on bi-objective approximation in the coupled task setting.

Abstract
Purpose
Despite lack of survival benefit, demand for contralateral prophylactic mastectomy (CPM) to treat unilateral breast cancer remains high. High uptake of CPM has been demonstrated in Midwestern rural women. Greater travel distance for surgical treatment is associated with CPM. Our objective was to examine the relationship between rurality and travel distance to surgery with CPM.

Methods
Women diagnosed with stages I–III unilateral breast cancer between 2007 and 2017 were identified using the National Cancer Database. Logistic regression was used to model likelihood of CPM based on rurality, proximity to metropolitan centers, and travel distance. A multinomial logistic regression model compared factors associated with CPM with reconstruction versus other surgical options.

Results
Both rurality (OR 1.10, 95% CI 1.06–1.15 for non-metro/rural vs. metro) and travel distance (OR 1.37, 95% CI 1.33–1.41 for those who traveled 50 + miles vs. < 30 miles) were independently associated with CPM. For women who traveled 30 + miles, odds of receiving CPM were highest for non-metro/rural women (OR 1.33 for 30–49 miles, OR 1.57 for 50 + miles; reference: metro women traveling < 30 miles). Non-metro/rural women who received reconstruction were more likely to undergo CPM regardless of travel distance (ORs 1.11–1.21). Both metro and metro-adjacent women who received reconstruction were more likely to undergo CPM only if they traveled 30 + miles (ORs 1.24–1.30).

Conclusion
The impact of travel distance on likelihood of CPM varies by patient rurality and receipt of reconstruction. Further research is needed to understand how patient residence, travel burden, and geographic access to comprehensive cancer care services, including reconstruction, influence patient decisions regarding surgery.
A labour of love: a review of Parry’s ‘Classes of Labour’
Authors: Sanchez Andrew 
Published: April 2023

AbstractThis review discusses Jonathan Parry’s 2020 monograph Classes of Labour in the context of the author’s career trajectory since the 1990s. The review critiques the conceptual framework with which the book understands class relations, and notes that the breadth of the study may be daunting for some readers. However, the review characterises the book as an artisanal masterpiece that shows an ethnographer working at the very peak of their abilities.

AbstractA well-defined terminology of fire-related variables is important for correct analyses and supporting knowledge-based decisions regarding the evaluation of building fires at the European level. After developing an overview of current practices for fire statistics in Part I, the terminology used and the data collected by the EU Member States and eight other countries regarding fire incidents, property damage and human losses were mapped to increase awareness of their practice and support a comprehensive assessment of several fire statistical datasets. A questionnaire was distributed to relevant authorities responsible for the collection, elaboration/analysis, and fire statistical data publications to define and select the essential variables for an appropriate fire assessment and fire incident description. Based on the results of the questionnaire able to identify the essential fire statistical variables and a detailed analysis of current definitions adopted in the fire statistics of the EU Member States and other countries, a common terminology is proposed to collect the necessary data in the EU Member States and obtain meaningful datasets based on standardised terms and definitions. The results will generate essential outputs to move towards harmonised fire statistics at the EU level and contribute to an appropriate analysis able to improve fire prevention and fire mitigation in building fires.

Published: April 2023

AbstractCommunities in several parts of sub-Saharan Africa (SSA) depend on natural resources for their sustenance. While growing pressure on such resources has been accused of framing conflicts, the power and convictions dimension of such conflicts remains relatively less explored. Taking the case of Cameroon, this paper undertakes an explorative analysis of power and convictions around land and linked natural resources. Specifically, the paper maps harmful convictions and their role in steering unequal access to land and linked natural resources; explores power manifestations among different categories of resource use actors; and discusses the role of different typologies of actors in shaping harmful convictions linked to land and other natural resources. Qualitative data derived from four communities in the greater south region informed this study: focus group discussions (14), key informants, and expert interviews (25) were employed. Using the actor-centred power analytical lens, the analysis entailed the use of directed content analysis, thematic analysis and narratives. The results indicate the following: Firstly, while ethnic/region-based and elitism-based harmful convictions significantly drive land resource access, gender-based and religious-based convictions are less recurrent. Secondly, while elitism-based actors exercise power through coercion, religious and political actors employ (dis)incentives and dominant information, respectively, in their quest for forestland. Thirdly, elitism-based and ethnic/region-based actors are at the centre of harmful convictions around land and linked natural resources. The results inform the actor-centred power concept, with emphasis on convictions around land and linked natural resources. Future studies should explore the conflict implications of these harmful convictions.

Published: April 2023

AbstractFrom the approach based on human rights, the psychosocial factors that facilitate entrepreneurial competences are encouraged for the career and communitarian development. The proper consideration of social cohesion among communities creates some facilitation for a better approach for people. We used a qualitative methodology applying 25 open-ended interviews and two discussion groups, and involving 42 professionals from Spain. We obtained a system of categories constituted by a group of psychosocial variables that key informant consider significant for entrepreneurial development. These results also identify the psychosocial learning and factors that need to be promoted through continuous educational actions within organizations, incentivizing an entrepreneurial career and contributing to sustainable development.
An Automated Approach to the Collatz Conjecture
Authors: Yolcu Emre , Aaronson Scott , Heule Marijn J. H. 
Published: April 2023

AbstractWe explore the Collatz conjecture and its variants through the lens of termination of string rewriting. We construct a rewriting system that simulates the iterated application of the Collatz function on strings corresponding to mixed binary–ternary representations of positive integers. We prove that the termination of this rewriting system is equivalent to the Collatz conjecture. We also prove that a previously studied rewriting system that simulates the Collatz function using unary representations does not admit termination proofs via natural matrix interpretations, even when used in conjunction with dependency pairs. To show the feasibility of our approach in proving mathematically interesting statements, we implement a minimal termination prover that uses natural/arctic matrix interpretations and we find automated proofs of nontrivial weakenings of the Collatz conjecture. Although we do not succeed in proving the Collatz conjecture, we believe that the ideas here represent an interesting new approach.
Fabrication of metal–polymer matching layers to improve some ultrasonic transducers for NDT and calibration
Authors: Barakat Mirham A. Y. 
Published: April 2023

AbstractThis paper investigates the impact of different matching layers on the ultrasonic transducers’ performance. Matching layers are mostly used to solve the acoustic impedance matching problem between the piezoelectric element and the test specimen. To design good matching layers, we merged the metal–polymer and mass–spring systems. Their thickness was also optimized using the quarter-wavelength approach. Silver, alumina, and copper served as mass components, while parylene served as the polymer spring component. This was the first time to use such matching materials with lead zirconate titanate (PZT) transducers. The transducers’ sensitivity increased, the beam diameter broadened, the signal-to-noise ratio reduced, and the echo-height increased. According to the findings, the developed matching layers were extremely efficient in upgrading PZT transducers, making them ideal for a variety of non-destructive ultrasonic applications such as identifying defects in various materials. In addition, the new developed transducers may be useful in calibration.

AbstractReligious and spiritual (R/S) struggles are defined as the occurrence of tension, conflict, or strain that focus on matters of ultimate significance perceived by people as sacred. The widespread prevalence of R/S struggles and the growing demand for research in this area created the need for a brief tool. Recently, the 14-item form of the Religious and Spiritual Struggles Scale was developed and validated (Exline et al. in Psychology of Religion and Spirituality, 2022a). Given the significance of the empirical research on R/S struggles, we implemented the project of structure verification, internal consistency confirmation, reliability, and nomological validation of the Polish variant of the RSS-14 through three separate studies. With respect to the internal structure of the RSS-14, the CFA from three studies confirmed the good fit of the six-factor model, very similar to the one obtained in the original version of the tool. Moreover, both the total score and the subscales had high reliability and acceptable stability over the three studies. With respect to the nomological analyses, R/S struggles were related negatively to life satisfaction, presence of meaning in life, self-esteem, social desirability, religious centrality, and positively with search for meaning, God’s disengagement, poorer health indicators, sleep problems, stress, and cognitive schemas (this category was the new element of our research). Polish 14-item version of the Religious and Spiritual Struggles Scale seems a valuable tool to assess religious strains.

Abstract
Background
The GLA c.337T > C (p.Phe113Leu) is a known pathogenic variant associated to late-onset Fabry disease phenotype with predominant cardiac manifestations. A founder effect was demonstrated in a large cohort in the Portuguese region of Guimarães. Herein we report an in-depth phenotype description of a cluster of five Southern Italy families.

Methods
Family pedigrees of five index males with the p.Phe113Leu variant were obtained and all at-risk relatives underwent biochemical and genetical screening test. Carriers of GLA p.Phe113Leu variant underwent subsequent multidisciplinary clinical and instrumental evaluation.

Results
Thirty-one (16 M, 15 F) individuals with p.Phe113Leu pathogenic variant were identified. Sixteen out of 31 patients (51.6%) had cardiac manifestations. Notably, myocardial fibrosis was found in 7/8 patients, of whom 2 were under 40 years. Stroke occurred in 4 patients. White matter lesions were detected in 12/19 patients and occurred in 2/10 of subjects under 40 years. Seven females complained of acroparesthesias. Renal involvement occurred in 10 patients. Angiokeratomas were evident in 9 subjects. Eyes, ear, gastrointestinal and pulmonary involvement occurred in the minority of subjects.

Conclusion
This study demonstrates that a cluster of subjects with p.Phe113Leu pathogenic variant is also present in Southern Italy. Disease manifestations are frequent in both sexes and may occur early in life. Cardiac involvement represents the core manifestation, but neurological and renal involvement is also frequent, suggesting that extra-cardiac complications deserve clinical attention.
Dynamics modeling method dedicated to system models with open- and closed-loop structures subjected to kinematic and task based constraints
Authors: Jarzębowska Elżbieta , Augustynek Krzysztof , Urbaś Andrzej 
Published: April 2023

AbstractThe paper presents a development of an automated computational procedure for constrained dynamics (CoPCoD) dedicated to derivation of dynamical models of mechanical systems, e.g. manipulators, both ground and space or mobile robotic systems, which can be composed of rigid and flexible links. They may be subjected to constraints, which are referred to as programmed, which may come from performance requirements, e.g. work or services a system is dedicated to. The CoPCoD structure offers systematic modeling of either open or closed loop constrained structures and results in computationally efficient numerical dynamical equations derivation. The CoPCoD development has its background in the generalized programmed motion equations (GPME) algorithm developed successfully for rigid models of mechanical systems subjected to high order nonholonomic constraints, however, the GPME was not fully automated for computer equation derivations. The two main motivations that underlie the CoPCoD development are to extend the GPME to flexible system models and make it fully automated to computer equation derivations for large classes of systems. The paper presents the general scheme of the CoPCoD architecture and examples which illustrate its application advantages.
Systematic literature review on impacts of COVID-19 pandemic and corresponding measures on mobility
Authors: Lee Kwang-Sub , Eom Jin Ki 
Published: April 2023

AbstractThe unprecedented COVID-19 outbreak has significantly influenced our daily life, and COVID-19’s spread is inevitably associated with human mobility. Given the pandemic’s severity and extent of spread, a timely and comprehensive synthesis of the current state of research is needed to understand the pandemic’s impact on human mobility and corresponding government measures. This study examined the relevant literature published to the present (March 2023), identified research trends, and conducted a systematic review of evidence regarding transport’s response to COVID-19. We identified key research agendas and synthesized the results, examining: (1) mobility changes by transport modes analyzed regardless of government policy implementation, using empirical data and survey data; (2) the effect of diverse government interventions to reduce mobility and limit COVID-19 spread, and controversial issues on travel restriction policy effects; and (3) future research issues. The findings showed a strong relationship between the pandemic and mobility, with significant impacts on decreased overall mobility, a remarkable drop in transit ridership, changes in travel behavior, and improved traffic safety. Government implemented various non-pharmaceutical countermeasures, such as city lockdowns, travel restrictions, and social distancing. Many studies showed such interventions were effective. However, some researchers reported inconsistent outcomes. This review provides urban and transport planners with valuable insights to facilitate better preparation for future health emergencies that affect transportation.
Caregivers of patients with malignant pleural mesothelioma: who provides care, what care do they provide and what burden do they experience?
Authors: Moore Adam , Bennett Bryan , Taylor-Stokes Gavin , Daumont Melinda J. 
Published: April 2023

Abstract
Purpose
There are limited data on the impact of caregiving for patients with malignant pleural mesothelioma (MPM) on the caregiver. We aimed to identify the demographic characteristics of these caregivers, the caregiving activities they perform and how caregiving burden impacts their work productivity and overall activity.

Methods
This cross-sectional study collected data from caregivers of patients with MPM across France, Italy, Spain and the United Kingdom January-June 2019. Caregiver demographics, daily caregiving tasks and the impact of caregiving on physical health was collected via questionnaire. The Zarit Burden Interview (ZBI) was used to assess caregiver burden and the Work Productivity and Activity Impairment questionnaire (WPAI) assessed impairment at work and during daily activities. Analyses were descriptive.

Results
Overall, 291 caregivers provided data. Caregivers were mostly female (83%), living with the patient (82%) and their partner/spouse (71%). Caregivers provided over five hours of daily emotional/physical support to patients. ZBI scores indicated 74% of caregivers were at risk of developing depression. Employed caregivers had missed 12% of work in the past seven days, with considerable presenteeism (25%) and overall work impairment (33%) observed. Overall, the mean activity impairment was 40%.

Conclusion
Caregivers provide essential care for those with MPM. We show caregiving for patients with MPM involves a range of burdensome tasks that impact caregivers’ emotional health and work reflected in ZBI and WPAI scores. Innovations in the management of MPM must account for how caregivers may be impacted and can be supported to carry out this important role.
The Role of Moral Experts in Secret Policy
Authors: Christie Lars 
Published: April 2023

AbstractIs it morally permissible to spy on allied countries? What type of otherwise criminal acts may covert intelligence agents commit in order to keep their cover? Is it permissible to subject children of high-value targets to covert surveillance? In this article, I ask whether democratically elected politicians ought to rely on advice from ethics committees in answering moral choices in secret policy. I argue that ethics committees should not advise politicians on how they ought to conclude secret moral choices. Instead, we can mandate ethics committees to provide advice aimed at improving the moral reasoning behind moral decisions in secret policy. Such advice, I argue, may add value to the decision process independently of whether it increases the chances of reaching morally correct conclusions.

AbstractWe provide a post-mission assessment of the science and data from the Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) investigation on the NASA Van Allen Probes mission. An overview of important scientific results is presented, covering all of the key wave modes and DC magnetic fields measured by EMFISIS. Discussion of the data products, which are publicly available, follows to provide users with guidance on characteristics and known issues of the measurements. We present guidance on the correct use of derived products, in particular, the wave-normal analysis (WNA) which yields fundamental wave properties such as polarization, ellipticity, and Poynting flux. We also give information about the plasma density derived from measuring the upper hybrid line in the inner magnetosphere.

Abstract
Solar stills are used in distant and arid areas to convert brackish or salty water into potable water fit for human use in a simple, affordable, and effective manner. Even when PCM materials are used, typical solar systems still have minimal production per day. In this study, experimental tests were carried out in order to increase the performance of a single-slope solar still combined with PCM material (paraffin wax) and a solar-powered electric heater. Two identical single-slope solar stills were designed, fabricated, and tested under the same climatic conditions during the summer and spring seasons of 2021 in Al-Arish, Egypt. The first is a conventional solar still (CVSS), and the other is also a conventional still but with PCM and an electric heater (CVSSWPCM). Several parameters were measured during the experiments, including sun intensity, meteorological aspects, cumulative freshwater production, average glass, and water temperatures and PCM temperature. The improved solar still was evaluated at different operating temperatures and was compared to the conventional traditional one. There were four cases studied: one case without a heater (paraffin wax only) and three other cases with a heater operating at 58 °C, 60 °C, and 65 °C, respectively. The experimental results revealed that activating the heater inside the paraffin wax increased daily production (i) in the spring by 2.38, 2.66, and 3.1 times and (ii) and in the summer by 2.2, 2.39, and 2.67 times at the three above-mentioned temperatures respectively (when compared to the traditional still). In addition, the maximum rate of daily freshwater production was achieved at paraffin wax temperature of 65 °C in both spring and summer (Case 5). Finally, the economic evaluation of the modified solar still was carried out according to cost per litre. The modified solar still with a heater operating at 65 °C has a higher exergoeconomic value than the traditional one. The maximum CO2 mitigation in cases 1 and 5 was approximately 28 tons and 160 tons, respectively.
