Published: May 2023

AbstractIt is standard cardiology practice for patients suffering from ventricular arrhythmias (the main cause of sudden cardiac death) belonging to high risk populations to be treated via the implantation of Subcutaneous Implantable cardioverter-defibrillators (S-ICDs). S-ICDs carry a risk of so-called T wave over sensing (TWOS), which can lead to inappropriate shocks that carry an inherent health risk. For this reason, according to current practice patients’ Electrocardiograms (ECGs) are manually screened by a cardiologist over 10 s to assess the T:R ratio—the ratio between the amplitudes of the T and R waves which is used as a marker for the likelihood of TWOS—with a plastic template. Unfortunately, the temporal variability of a patient’ T:R ratio can render such a screening procedure, which relies on an inevitably short ECG segment due to its manual nature, unreliable. In this paper, we propose and investigate a tool based on deep learning for the automatic prediction of the T:R ratios from multiple 10-second segments of ECG recordings capable of carrying out a 24-hour automated screening. Thanks to the significantly increased screening window, such a screening would provide far more reliable T:R ratio predictions than the currently utilized 10-second, template-based, manual screening is capable of. Our tool is the first, to the best of our knowledge, to fully automate such an otherwise manual and potentially inaccurate procedure. From a methodological perspective, we evaluate different deep learning model architectures for our tool, assess a range of stochastic-gradient-descent-based optimization methods for training their underlying deep-learning model, perform hyperparameter tuning, and create ensembles of the best performing models in order to identify which combination leads to the best performance. We find that the resulting model, which has been integrated into a prototypical tool for use by clinicians, is able to predict T:R ratios with very high accuracy. Thanks to this, our automated T:R ratio detection tool will enable clinicians to provide a completely automated assessment of whether a patient is eligible for S-ICD implantation which is more reliable than current practice thanks to adopting a significantly longer ECG screening window which better and more accurately captures the behavior of the patient’s T:R ratio than the current manual practice.

AbstractSexual and dating violence (SDV) by male youth (≤ 25 years)—including sexual harassment, emotional partner violence, and rape—is a worldwide problem. The goal of this preregistered (PROSPERO, ID: CRD42022281220) systematic review was to map existing SDV prevention programs aimed at male youth, including their characteristics (e.g., content, intensity), intended psychosexual outcomes, and empirically demonstrated effectiveness, guided by the principles of the theory of planned behavior (TPB). We conducted searches in six online databases for published, peer-reviewed quantitative effectiveness studies on multi-session, group focused, and interaction based SDV prevention programs for male youth ending March 2022. After screening of 21,156 hits using PRISMA guidelines, 15 studies on 13 different programs, from four continents were included. Narrative analysis showed, first, broad ranges in program intensity (2–48 h total), and few program curricula included explicit discussion of relevant aspects of the TPB. Second, programs’ main intended psychosexual outcomes were to change SDV experiences, or related attitudes, or norms. Third, significant effects were found mostly on longer term behaviors and short-term attitudes. Other theoretical proxies of SDV experiences, such as social norms and perceived behavioral control, were sparsely investigated; thus, program effectiveness on these outcomes remains largely unknown. Assessed with the Cochrane Risk of Bias Tool, moderate to serious risk of bias arose in all studies. We present concrete suggestions for program content, such as explicit attention to victimization and masculinity and discuss best practices for evaluation research, including assessments of program integrity, and examining relevant theoretical proxies of SDV.

Abstract

There is evidence that physical activity positively influences cognition and academic outcomes in childhood. This systematic review used a three-level meta-analytic approach, which handles nested effect sizes, to assess the impact of physical activity interventions. Ninety-two randomised control trials in typically developing children (5–12 years old, N = 25,334) were identified. Control group type and intervention characteristics including duration, frequency, and teacher qualification were explored as potential moderators. Results showed physical activity interventions improved on-task behaviour with a large effect size (g = 1.04, p = 0.03 (95% CI: 0.08–2.00), very low-certainty evidence) and led to moderate improvements in creativity (g = 0.70, p < 0.01 (0.20–1.20), low-certainty evidence). Small beneficial effects were found for fluid intelligence (g = 0.16, p = 0.03 (0.02, 0.30), moderate-certainty evidence) and working memory (g = 0.18, p = 0.01 (0.07–0.29), very low-certainty evidence), but no overall benefit was observed for attention, inhibitory control, planning, cognitive flexibility or academic outcomes. Heterogeneity was high, and moderator analyses indicated beneficial effects of physical activity (PA) with academic instruction of 6–10-week duration with moderate or moderate to vigorous intensity on mathematics outcomes and enriched PA programmes on language outcomes. In contrast, aerobic PA with moderate to vigorous intensity benefitted executive function outcomes. These results therefore suggest differential mechanisms of impact of different types of PA on different aspects of cognition.

Published: May 2023

AbstractSediment yield estimation along with identification of soil erosion mechanisms is essential for developing sophisticated management approaches, assessing, and balancing different management scenarios and prioritizing better soil and water conservation planning and management. At the watershed scale, land management practices are commonly utilized to minimize sediment loads. The goal of this research was to estimate sediment yield and prioritize the spatial dispersion of sediment-producing hotspot areas in the Nashe catchment using the Soil and Water Assessment Tool (SWAT). Moreover, to reduce catchment sediment output, this study also aims to assess the effectiveness of certain management practices. For calibration and validation of the model, monthly stream flow and sediment data were utilized. The model performance indicators show good agreement between measured and simulated stream flow and sediment yields. The study examined four best management practice (BMP) scenarios for the catchment’s designated sub-watersheds: S0 (baseline scenario), S1 (filter strip), S2 (stone/soil bunds), S3 (contouring), and S4 (terracing). According to the SWAT model result, the watershed’s mean yearly sediment output was 25.96 t/ha. yr. under baseline circumstances. The model also revealed areas producing the maximum sediment quantities indicating the model’s effectiveness for implementing and evaluating the sensitivity of sediment yield to various management strategies. At the watershed scale, treating the watershed with various management scenarios S1, S2, S3, and S4 decreased average annual sediment yield by 34.88%, 57.98%, 39.55%, and 54.77%, respectively. The implementations of the soil/stone bund and terracing scenarios resulted in the maximum sediment yield reduction. The findings of this study will help policymakers to make better and well-informed decisions regarding suitable land use activities and best management strategies.
Rubbing salt in the wound? A large-scale investigation into the effects of refactoring on security

Published: May 2023

AbstractSoftware refactoring is a behavior-preserving activity to improve the source code quality without changing its external behavior. Unfortunately, it is often a manual and error-prone task that may induce regressions in the source code. Researchers have provided initial compelling evidence of the relation between refactoring and defects, yet little is known about how much it may impact software security. This paper bridges this knowledge gap by presenting a large-scale empirical investigation into the effects of refactoring on the security profile of applications. We conduct a three-level mining software repository study to establish the impact of 14 refactoring types on (i) security-related metrics, (ii) security technical debt, and (iii) the introduction of known vulnerabilities. The study covers 39 projects and a total amount of 7,708 refactoring commits. The key results show that refactoring has a limited connection to security. However, Inline Method and Extract Interface statistically contribute to improving some security aspects connected to encapsulating security-critical code components. Extract Superclass and Pull Up Attribute refactoring are commonly found in commits violating specific security best practices for writing secure code. Finally, Extract Superclass and Extract & Move Method refactoring tend to occur more often in commits contributing to the introduction of vulnerabilities. We conclude by distilling lessons learned and recommendations for researchers and practitioners.
Has Montefiore and Formosa resisted the Gamer’s Dilemma?
Authors: Luck Morgan 
Published: May 2023

AbstractMontefiore and Formosa (Ethics Inf Technol 24:31, 2022) provide a useful way of narrowing the Gamer’s Dilemma to cases where virtual murder seems morally permissible, but not virtual child molestation. They then resist the dilemma by theorising that the intuitions supporting it are not moral. In this paper, I consider this theory to determine whether the dilemma has been successfully resisted. I offer reason to think that, when considering certain variations of the dilemma, Montefiore and Formosa’s theory may not be the most likely theory available to us.
A Workplace Environmental Scan of Employed Carers During COVID-19

Published: May 2023

AbstractThe carer-employee experience has undergone multiple shifts during the COVID-19 pandemic. This study seeks to understand how changes in the workplace as a result of the pandemic have impacted employed carers with their ability to perform both care obligations and paid work responsibilities. Using an online workplace-wide survey at a large Canadian firm, we conducted an environmental scan of: the current state of workplace supports and accommodations, supervisor attitudes, and carer-employee burden and health. Our findings demonstrate that while employees are generally in good health, care burden and time spent caregiving has been higher during COVID-19. Notably, employee presenteeism is higher during the pandemic than it was previously, with carer-employees experiencing significantly reduced levels of co-worker support. The most common workplace adaptation to COVID-19, work-from-home, was preferred by all employees as it allowed greater schedule control. However, this comes at the cost of reduced communications and sense of workplace culture, especially for carer-employees. We identified several actionable changes within the workplace, including: greater visibility of existing carer resources, and standardized training of managers on carer issues.

Published: May 2023

AbstractThis article presents the results of a study on laser ablation of selected thermoplastic polymers using an economical fiber laser with a scanning galvanometer system and an IR laser with a wavelength ofλ = 1064 nm. The study aimed to develop comparative characteristics of the ablation processes of commonly used constructional thermoplastics, namely acrylonitrile butadiene styrene terpolymer (ABS), polystyrene (PS), poly(ethylene terephthalate) (PET), polylactide (PLA), and polyamide 6 (PA6). The ablation characteristics of the tested materials were determined, and the ablation depth and surface structures were calculated and presented. A comparative analysis of the contact angle, surface free energy, and strength of adhesive connections of materials modified with laser radiation and unmodified was performed. The study showed that the dynamics of laser ablation were much higher in ABS, PS, PET, and PC than in PLA and PA6. Although modification of the surface layer of the polymeric material did not have a significant impact on the surface free energy and wettability of the sample surface, it increased the strength of adhesive connections even several times (in ABS, PS, PET) with the lowest energy consumption. The results also demonstrated that some polymers, such as ABS or PS, can be effectively treated with near-infrared laser radiation of this wavelength, which is particularly important for surface layer modification and marking of details.
Overcoming Challenges of Intimacy: Male Child Sexual Abuse Survivors’ Experiences of Achieving Healthy Romantic Relationships in Sweden
Authors: Petersson Charlotte C. , Plantin Lars 
Published: May 2023

Abstract
Purpose
Studies on sexual health following male child sexual abuse (CSA) have identified the negative effects of such experiences on body functioning, but little is known about male CSA survivors’ ability to create emotional and physical closeness in romantic relationships. The purpose of this article is to explore how male CSA survivors perceive, experience and develop intimacy in romantic relationships, including both the challenges they face and the positive changes that enable them to grow and achieve healthy relationships.

Method
The study has employed a qualitative research approach and is based on in-depth interviews conducted among adult male CSA survivors residing in Sweden. Participants were recruited through civil society organizations and an ad in a daily newspaper. Using reflexive thematic analysis, the results are presented in relation to two themes: (a) challenges of intimacy; and (b) building trust and close relationships.

Results
The results show that participants desired couple relationships that included both sexual and emotional intimacy. The challenges of intimacy were related to compromised sexual identity, sexual dysfunctions and compulsions, emotional dysregulation, and body shame. Efforts to achieve intimacy were facilitated by disclosing abuse experiences, developing emotional bonds or awareness, embracing sensitivity, and having an empathetic and supportive partner.

Conclusions
Reconstructions of abuse histories were both challenged and facilitated by the accessibility of various and shifting ideas about masculinities that co-exist in Sweden, which were important sources for meaning making and assisted the men in developing positive valuations of themselves as men.

Published: May 2023

Abstract
Context
The Mediterranean mountains have witnessed the revegetation of former pasture and cultivated fields since the mid-20th century. The process started when the mountains joined a dynamic and competitive market, which led to depopulation, abandoning cultivated fields, and a reduction in extensive livestock farming.

Objectives
We investigate changes in land use and land cover (LULC) and landscape structure in a valley of the Central Pyrenees in 1956, 1981 and 2017, and we discuss the implications for land management within a multidisciplinary context.

Methods
Aerial photographs are used to map the LULC in 1956, 1981 and 2017, followed by landscape ecology metrics and indices to analyse the structure of the landscape.

Results
The results show: (i) a reduction in cultivated area (-42%) and pastures (-63%) in the montane belt between 1956 and 2017, while forests doubled in area; (ii) changes in LULC are more significant in the montane belt than in subalpine and alpine areas; (iii) based on the Kappa index, it was found that the 29% of the area had undergone changes in LULC between 1956 and 2017, with the changes being greater in the first period (1956–1981) than in the second (1981–2017); (iv) the structure and heterogeneity of the landscape shows an increase between 1956 and 1981, and a change in trend from 1981 to 2017, so that the landscape is more homogeneous in 2017 than in 1956.

Conclusion
The discussion suggests the need to maintain and recover mosaic landscapes, since their structure is akin to traditional cultural ones, to increase biodiversity and sustainability, and provide ecosystem services to the population.
Angiotensin converting enzyme 2 gene expression and markers of oxidative stress are correlated with disease severity in patients with COVID-19

Published: May 2023

Abstract
Background
Oxidative stress is thought to play a significant role in the pathogenesis and severity of COVID-19. Additionally, angiotensin converting enzyme 2 (ACE2) expression may predict the severity and clinical course of COVID-19. Accordingly, the aim of the present study was to evaluate the association of oxidative stress and ACE2 expression with the clinical severity in patients with COVID-19.

Methods and results
The present study comprised 40 patients with COVID-19 and 40 matched healthy controls, recruited between September 2021 and March 2022. ACE 2 expression levels were measured using Hera plus SYBR Green qPCR kits with GAPDH used as an internal control. Serum melatonin (MLT) levels, serum malondialdehyde (MDA) levels, and total antioxidant capacity (TAC) were estimated using ELISA. The correlations between the levels of the studied markers and clinical indicators of disease severity were evaluated. Significantly, lower expression of ACE2 was observed in COVID-19 patients compared to controls. Patients with COVID-19 had lower serum levels of TAC and MLT but higher serum levels of MDA compared to normal controls. Serum MDA levels were correlated with diastolic blood pressure (DBP), Glasgow coma scale (GCS) scores, and serum potassium levels. Serum MLT levels were positively correlated with DBP, mean arterial pressure (MAP), respiratory rate, and serum potassium levels. TAC was correlated with GCS, mean platelet volume, and serum creatinine levels. Serum MLT levels were significantly lower in patients treated with remdesivir and inotropes. Receiver operating characteristic curve analysis demonstrates that all markers had utility in discriminating COVID-19 patients from healthy controls.

Conclusions
Increased oxidative stress and increased ACE2 expression were correlated with disease severity and poor outcomes in hospitalized patients with COVID-19 in the present study. Melatonin supplementation may provide a utility as an adjuvant therapy in decreasing disease severity and death in COVID-19 patients.
On the Physical Nature of the so-Called Prominence Tornadoes

AbstractThe term ‘tornado’ has been used in recent years to describe several solar phenomena, from large-scale eruptive prominences to small-scale photospheric vortices. It has also been applied to the generally stable quiescent prominences, sparking a renewed interest in what historically was called ‘prominence tornadoes’. This paper carries out an in-depth review of the physical nature of ‘prominence tornadoes’, where their name subconsciously makes us think of violent rotational dynamics. However, after careful consideration and analysis of the published observational data and theoretical models, we conclude that ‘prominence tornadoes’ do not differ in any substantial way from other stable solar prominences. There is simply no unequivocal observational evidence of sustained and coherent rotational movements in quiescent prominences that would justify a distinct category of prominences sharing the name with the well-known atmospheric phenomenon. The visual impression of the column-like silhouettes, the perceived helical motions, or the suggestive Doppler-shift patterns all have a simpler, more likely explanation. They are a consequence of projection effects combined with the presence of oscillations and/or counter-streaming flows. ‘Prominence tornadoes’ are thus just manifestations of the complex nature of solar prominences when observed in specific projections. These coincidental viewing angles, together with the presence of fine-structure dynamics and simple yet profoundly distorting projection effects, may sometimes play havoc with our intuitive understanding of perceived shapes and motions, leading to the incorrect analogy with atmospheric tornadoes.
