Published: August 2022

Wearable sensors are an important tool in the study of head acceleration events and head impact injuries in sporting and military activities. Recent advances in sensor technology have improved our understanding of head kinematics during on-field activities; however, proper utilization and interpretation of data from wearable devices requires careful implementation of best practices. The objective of this paper is to summarize minimum requirements and best practices for on-field deployment of wearable devices for the measurement of head acceleration events in vivo to ensure data evaluated are representative of real events and limitations are accurately defined. Best practices covered in this document include the definition of a verified head acceleration event, data windowing, video verification, advanced post-processing techniques, and on-field logistics, as determined through review of the literature and expert opinion. Careful use of best practices, with accurate acknowledgement of limitations, will allow research teams to ensure data evaluated is representative of real events, will improve the robustness of head acceleration event exposure studies, and generally improve the quality and validity of research into head impact injuries.

Published: August 2022

A combined numerical and experimental investigation is carried out to analyze the cycle-to-cycle variations (CCV) in an optically accessible spark-ignition engine with port fuel injection. A stable and an unstable operating condition is considered. Well-established turbulence, combustion, and ignition models are employed in the large-eddy simulations (LES). High-speed measurements of the velocity field via particle image velocimetry and flame imaging in the tumble plane are conducted in the experiments. A detailed comparison between LES and experiments is carried out, including the in-cylinder pressure, the flow fields, the spatial flame distribution, and the fields conditioned on fast and slow cycles. Good agreement is achieved for the variables considering all cycles; yet, some discrepancies are observed for the conditionally averaged quantities. A systematic quantitative correlation analysis between the selected influencing variables and the CCV is presented, in which the influencing variables are extracted from different length scales (r = 3 mm, 12 mm, and 43 mm) and the CCV are distinguished between the early flame kernel development and later flame propagation. Even though the most relevant influencing parameters are different for the two operating conditions, the location of the coherent vortex structure is found to be important for the CCV of both cases.
Altruist Talk May (also) Be Cheap: Revealed Versus Stated Altruism as a Predictor in Stated Preference Studies
Authors: Iversen Endre Kildal , Grimsrud Kristine , Mitani Yohei , Lindhjem Henrik
Published: August 2022

Altruistic preferences have been found to be important for explaining the substantial non-use values identified in numerous stated preference surveys. However, studies analysing the effect of altruism on willingness to pay (WTP) have underestimated the challenges of measuring altruism by stated measures. We exploit a naturally occurring decision domain to investigate the role of altruism in stated preference studies. We employ a novel dataset, collected from an Internet survey panel, that contains respondents’ past donations of earned survey coins to charities and use these data to analyse the effect of donation behaviour on the same respondents’ WTP. We analyse donation behaviour across two contingent valuation surveys on environmental topics. Donators are proven givers in an anonymous and unrelated setting, much like decision-making in a dictator game. We find that respondents’ past donations are associated with higher WTP, even after controlling forstatedmeasures of altruism, ecological, and environmental attitudes. The results suggest that measures of stated altruism fail to capture important aspects of altruism, implying that previous studies of altruism based on such measures may be questioned. The results also support research demonstrating that altruistic behaviour in one decision domain is a good predictor of altruistic behaviour in other domains.
Using the Constitutionality Framework to Understand Alliances, Collective Action, and Divisions Between Indigenous and Peasant Communities in the Chaco Salteño
Authors: Tschopp Maurice , Inguaggiato Carla , Saravia Rodrigo Chavez , Ceddia Michele Graziano
Published: August 2022

This article analyzes bottom-up institution-building processes in a region considered deforestation and environmental degradation hotspot. Utilizing the constitutionality approach developed by Haller, Acciaioli, and Rist (2016), we examine two recent cases of bottom-up institution-building in the department of Rivadavia, Chaco Salteño, Argentina. We highlight the similarities and differences between both constitutionality processes and identify various weaknesses in the two cases. We argue that constitutionality, understood as a process, has occurred to different (incomplete) degrees in each case. Finally, we show that external catalyzing agents play a decisive role in enabling or hampering the constitutionality process. Our study contributes to the literature on common-pool resource governance by highlighting how collective action can lead to participatory-development processes.
Misunderstood Stoicism: The negative Association Between Stoic Ideology and well-Being
Authors: Karl Johannes Alfons , Verhaeghen Paul , Aikman Shelley N. , Solem Stian , Lassen Espen R. , Fischer Ronald
Published: August 2022

Ancient philosophy proposed a wide range of possible approaches to life which may enhance well-being. Stoic philosophy has influenced various therapeutic traditions. Individuals today may adopt an approach to life representing a naive Stoic Ideology, which nevertheless reflects a misinterpretation of stoic philosophy. How do these interpretations affect well-being and meaning in life? We examine the differential effects of Stoic Ideology on eudaimonic versus hedonic well-being across three cultural contexts. In this pre-registered study, across samples in New Zealand (N = 636), Norway (N = 290), and the US (N = 381) we found that a) Stoic Ideology can be measured across all three contexts and b) Converging evidence that Stoic Ideology was negatively related to both hedonic well-being and eudaimonic well-being. Focusing on specific relationships, we found especially pronounced effects for Taciturnity (the desire to not express emotions) and Serenity (the desire to feel less emotions). Despite being a misinterpretation of stoic philosophy, these findings highlight the important role of individuals’ orientations to emotional processing for well-being.
Flame retarded polymer systems based on the sol-gel approach: recent advances and future perspectives
Authors: Bifulco Aurelio , Imparato Claudio , Aronne Antonio , Malucelli Giulio
Published: August 2022

The ease of flammability of polymers represents a key issue that limits their applications in different advanced sectors. In this context, a reliable and effective solution regards the use of flame retardants, i.e., additives that are able to slow down (or even stop) the flame propagation and to enhance the resistance to an irradiative heat flux. Among the different flame retardants designed, synthesized, and applied up-to-now, the utilization of inorganic particles, inorganic and hybrid organic-inorganic coatings has gathered a great interest from either the academic and industrial community, as these structures can provide remarkable flame retardant features to different polymer systems, in which they are embedded or applied onto. In particular, the in situ generation (through sol-gel processes, i.e. hydrolysis and condensation reactions from tailored alkoxide precursors) of ceramic phases, either in the form of particles or as surface coatings, has clearly demonstrated its effectiveness in creating a physical barrier that limits the degradation of the polymer when subjected to the application of a flame or an irradiative heat flux. It also lowers the heat and mass transfer from the degrading polymer to the surroundings and vice versa, hence providing an overall enhancement of heat and fire resistance. This review work seeks to provide an up-to-date overview of the most recent advances in the use of sol-gel methods for conferring flame retardant features to bulk polymers, cellulosic textiles (cotton), and polymer foams. In addition, the current limitations and the potential progresses of these approaches are discussed.
Recycling of metallocene isotactic polypropylene: importance of antioxidants
Authors: Blázquez-Blázquez Enrique , Díez-Rodríguez Tamara M. , Pérez Ernesto , Cerrada María L.
Published: August 2022

Recycling of plastics is absolutely essential in a circular economy, especially in the case of commodity polymers from fossil resources, like isotactic polypropylene (iPP). Therefore, evaluation of the factors that are decisive for an optimum performance of the recycled based materials becomes mandatory for the obtainment of new products with optimal properties. One of the most important aspects is the protection of the plastics materials not only against the external degradation agents, but also from the radicals generated during their previous service life. Accordingly, several materials have been prepared by extrusion based on virgin iPP with different amounts of the same polypropylene severely degraded, which has been used as model component to be recycled. Previous to the extrusion, a mixture of antioxidants was added to all the samples, and special attention has been paid to consumption of those additives during the extrusion. The results show an increasing reduction of antioxidants with rising content of the degraded material. But, importantly, a rather analogous mechanical response has been found for all the recycled materials in relation to the virgin iPP, pointing out a satisfactory dilution effect of the existing degradation points within the virgin polymeric chains, and indicating the very relevant action of the antioxidants used.
“There is ‘Plenty’ of Grace—it is Not a Limited Commodity!:” Experiences of Grace in Australian Faith Communities During the Pandemic
Authors: Hyde Brendan , Joseph Dawn
Published: August 2022

During the pandemic years of 2020 and 2021, Melbourne in Australia endured one of the longest lockdowns in the world. Although the severe restrictions for faith communities in particular posed many setbacks, new opportunities for worship were experienced. This paper focuses on a research project that explored hope, grace, and resilience during COVID-19 in Melbourne. A total of 106 participants from a variety of Christian denominations in Melbourne completed an online survey in relation to the notion of grace. Thematic analysis of the qualitative data was employed to explore the lived experiences of the participants. Two overarching themes—God’s grace offers favour, and God’s grace provides strength and builds resilience—are discussed. The findings indicate that while grace is bountiful through faith, it can also be found in unexpected places within faith settings and the wider community. While generalizations from this study cannot be made to other faith communities, recommendations are offered in relation to ways in which ‘church’ may be experienced in 2022 and beyond. The study showed that “there is ‘plenty’ of grace”. Its transformational power offers hope and builds resilience as God’s grace “is not a limited commodity!”
The given and the hard problem of content
Authors: Salis Pietro
Published: August 2022

Wilfrid Sellars’ denunciation of the Myth of the Given was meant to clarify, against empiricism, that perceptual episodes alone are insufficient to ground and justify perceptual knowledge. Sellars showed that in order to accomplish such epistemic tasks, more resources and capacities, such as those involved in using concepts, are needed. Perceptual knowledge belongs to the space of reasons and not to an independent realm of experience.

Dan Hutto and Eric Myin have recently presented the Hard Problem of Content as an ensemble of reasons against naturalistic accounts of content. In a nutshell, it states that covariance relations—even though they are naturalistically acceptable explanatory resources—do not constitute content. The authors exploit this move in order to promote their preferred radical enactivist and anti-representationalist option, according to which, basic minds—the lower stratum of cognition—do not involve content.

Although it is controversial to argue that the Hard Problem of Content effectively dismisses naturalistic theories of representation, a central aspect of it—the idea that information as covariance does not suffice to explain content—finds support among the defenders of classical cognitive representationalism, such as Marcin Miłkowski. This support—together with the acknowledgment this remark about covariance is a point already made by Sellars in his criticism of the Myth of the Given—has a number of interesting implications. Not only is it of interest for the debates about representationalism in cognitive science, where it can be understood as an anticipatory move, but it also offers some clues and insights for reconsidering some issues along Sellarsian lines—a conflation between two concepts of representation that is often assumed in cognitive science, a distinction between two types of relevant normativities, and a reconsideration of the naturalism involved in such explanations.
Sexual Aggression among Women and Men in an Iranian Sample: Prevalence and Correlates
Authors: Malayeri Shera , Nater Christa , Krahé Barbara , Sczesny Sabine
Published: August 2022

This pre-registered study examined the prevalence and correlates of sexual aggression in a sample of 530 Iranians (322 women, 208 men) with a behaviorally specific questionnaire distinguishing between different coercive strategies, victim-perpetrator relationships, and sexual acts. Significantly more women (63.0%) than men (51.0%) experienced at least one incident of sexual aggression victimization since the age of 15 years, and significantly more men (37.0%) than women (13.4%) reported at least one incident of sexual aggression perpetration. In women and men, the experience of child sexual abuse predicted sexual victimization and sexual aggression perpetration after the age of 15 years, both directly and indirectly through higher engagement in risky sexual behavior. Greater endorsement of hostile masculinity among men explained additional variance in the prediction of sexual aggression perpetration. This research is a first step towards documenting and explaining high rates of sexual aggression victimization and perpetration among Iranian women and men, providing important information for sex education as well for the prevention of sexual aggression. However, to achieve these goals, we highlight the need for systematic actions in all educational, social, and legal sectors of Iranian society.
The ‘Gender Life-Satisfaction/Depression Paradox’ Is an Artefact of Inappropriate Control Variables
Authors: Bartram David
Published: August 2022

Previous research has suggested that there is a ‘gender paradox’ associated with life satisfaction and depression: women are said to have higher levels of life satisfaction on average but also a higher likelihood of experiencing depression. That finding comes from quantitative analyses that include socio-demographic control variables. In this article I show that the inclusion of these control variables leads to biased results. In general, controls are to be selected on the basis that they are antecedents of the focal independent variable (as well as the dependent variable). When the focal independent variable is gender (or, more precisely, sex), no controls are required: there are no determinants of life satisfaction that also determine someone’s sex. If we include socio-demographic controls, we get biased results – because the controls themselves are affected by sex. More precisely: if we include controls (e.g. for income) to discern the difference between women’s and men’s life satisfaction, we get a result that fails to reflect the way women experience specific disadvantages (e.g. lower income) that contribute to lower life satisfaction. The same points apply to an analysis of depression. In a properly specified model (using data from the European Social Survey), there is no difference between women’s and men’s life satisfaction – so, there is no paradox with respect to depression.
ADS-B classification using multivariate long short-term memory–fully convolutional networks and data reduction techniques
Authors: Bolton Sarah , Dill Richard , Grimaila Michael R. , Hodson Douglas
Published: August 2022

Researchers typically increase training data to improve neural net predictive capabilities, but this method is infeasible when data or compute resources are limited. This paper extends previous research that used long short-term memory–fully convolutional networks to identify aircraft engine types from publicly available automatic dependent surveillance-broadcast (ADS-B) data. This research designs two experiments that vary the amount of training data samples and input features to determine the impact on the predictive power of the ADS-B classification model. The first experiment varies the number of training data observations from a limited feature set and results in 83.9% accuracy (within 10% of previous efforts with only 25% of the data). The findings show that feature selection and data quality lead to higher classification accuracy than data quantity. The second experiment accepted all ADS-B feature combinations and determined that airspeed, barometric pressure, and vertical speed had the most impact on aircraft engine type prediction.
Fertility-Sparing and Less Radical Surgery for Cervical Cancer
Authors: Batman Samantha H. , Schmeler Kathleen M.
Published: August 2022

Purpose of Review

Patients with early-stage cervical cancer who desire future fertility may be candidates for less radical surgery. We review the literature supporting this approach in early-stage disease.

Recent Findings

Retrospective data have shown that in carefully selected patients, the risk of parametrial involvement is less than 1%. This has led to interest in moving away from radical surgery towards more conservative approaches. Data from the newly published ConCerv trial, a prospective study evaluating the feasibility of conservative surgery in women with early-stage, low-risk cervical carcinoma, suggest that conservative surgery is feasible and safe in this patient population. Furthermore, neoadjuvant chemotherapy is being assessed as an option to extend fertility-sparing treatment to a larger group of women.

Less radical surgery may be appropriate for carefully selected women with early-stage, low-risk cervical cancer, including those desiring future fertility.
Ameliorating Inflammation in Insulin-resistant Rat Adipose Tissue with Abdominal Massage Regulates SIRT1/NF-κB Signaling

Published: August 2022

It was the aim of this study to determine whether abdominal massage reverses high-fat diet-induced insulin resistance compared with RSV treatment. A total of sixty male Sprague-Dawley rats were randomly placed in one of four groups:the non-fat diet (NFD), the high-fat diet (HFD), the HFD with abdominal massage (HFD+ AM), and the HFD plus resveratrol (HFD+ RSV). For eight weeks, rats were fed high-fat diets to create insulin resistance, followed by six weeks of either AM or RSV. Molecular mechanisms of adipogenesis and cytokine production in rats with high-fat diets were investigated. The model rat adipose tissue showed significant improvements in obesity, glucose intolerance, and the accumulation of lipid in the body [the total cholesterol level (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C)], metabolic effects of glucose [The fasting blood glucose (FBG), Fasting insulin levels (FINS)], inflammatory status [interleukin-6 (IL-6) and tumor necrosis factor (TNF)-α, C-reactive protein (CRP)], and macrophage polarization after AM or RSV treatment. Further, AM increased SIRT1/NF-κB signaling in rat adipose tissue. Accordingly, in rat adipose tissue, our results indicate that AM regulates the secretion of proinflammatory cytokines, blood sugar levels, and related signaling pathways, contributing to improvement of IR, which may serves as a new therapeutic approach for the treatment for IR.
Comparative Study of Elabela and Apelin on Apelin Receptor Activation Through β-Arrestin Recruitment
Authors: Zhang Hong , Chen Juan , Shi Min , Xu Feng , Zhang Xiangcheng , Gong Da-Wei
Published: August 2022

Apelin receptor (APJ) ligands elabela (ELA) and apelin have divergent distributions and function differently in vitro and in vivo. Whether differences exist in their capacity of recruitment of β-arrestins (ARRBs) to APJ remains unknown. The aim of the current study was to investigate the different effects of ELA and apelin on the interaction between APJ and ARRBs in live cells by NanoBiT®. NanoBiT® system is a new technology for studying protein–protein interaction in real-time in live cells, based on the emission of luminescence when two split components of NanoLuc luciferase, large Bit (LgBit) and small Bit (SmBit), complement each other to form an enzymatically active entity. We tagged the APJ and ARRBs with LgBit or SmBit and then evaluated their interactions in transiently transfected HEK293T cells, and determined the signal strength yielded as a result of the interaction. We also investigated the concentration-dependent response of the APJ-ARRB interaction in response to ELA and apelin. Finally, we assessed the effect of F13A, an APJ antagonist which is structurally very similar to apelin-13, on ELA- and apelin-mediated APJ-ARRB interactions. The NanoLuc® luciferase signal was highest in the pair of APJ-LgBit with SmBit-ARRB1 or SmBit-ARRB2. NanoLuc® luciferase signal increased in a concentration-dependent manner from 0.1 nM to 10 μM in response to ELA or apelin. Interestingly, ELA elicited weaker APJ-ARRB interaction signals than apelin. Pre-treatment with F13A potently reduced the APJ-ARRB interaction in response to both ELA and apelin. Our results demonstrated that both ELA and apelin promoted the interaction of APJ and ARRBs in a concentration-dependent manner, and ELA is less efficacious than apelin in inducing the recruitment of ARRBs to APJ, providing a biased functional aspect of ELA vs. apelin at the receptor signaling level. Additionally, ELA and apelin may share the same binding site(s) or pocket(s) at the APJ level.
Spatiotemporal Patterns of Cyclist Collisions in Germany: Variations in Frequency, Severity of Injury, and Type of Collision in 2019
Authors: Harkort Lasse , Walker Byron Blake , Lakes Tobia
Published: August 2022

Cycling has gained increasing interest in Germany in recent years due to its manifold environmental, societal, and economic benefits. However, the number of cyclist collisions resulting in injury or death remains high and little is known about regional variations in frequency, severity of injury, and type of collision. This study investigates spatial and temporal patterns and characteristics of cyclist collisions across Germany in 2019. Using a detailed cyclist collision dataset for most German federal states, we identified statistically significant regional differences in frequency, severity of injury, and type of collision. To facilitate this and future cyclist collision surveillance studies in Germany, we developed and published a custom R package to download and combine the collision data with geographical data. Our analysis reveals that densely populated regions exhibit higher collision rates and a higher share of collisions involving turns, but lower severity of injuries and a lower share of collisions whilst driving in a straight line, a higher collision frequency during the work week compared to weekends, and a higher collision frequency peak during morning rush hour. We also observed a markedly high share of fatal bicycle-truck collisions in densely populated regions. In contrast, rural regions show lower collision rates, but a higher share of severe collisions, a higher share of collisions whilst driving in a straight line, as well as higher collision frequencies during weekends and summer months. Our findings underscore the complex and multifaceted geographical variations in collisions involving cyclists. The results of this study suggest that a one-size-fits-all approach to collision prevention infrastructure and policy may be insufficient for addressing variations in risk, and that future efforts to improve cyclist safety should be tailored to the local geographical context.
Single candidate optimizer: a novel optimization algorithm
Authors: Shami Tareq M. , Grace David , Burr Alister , Mitchell Paul D.
Published: August 2022

Single-solution-based optimization algorithms have gained little to no attention by the research community, unlike population-based approaches. This paper proposes a novel optimization algorithm, called Single Candidate Optimizer (SCO), that relies only on a single candidate solution throughout the whole optimization process. The proposed algorithm implements a unique set of equations to effectively update the position of the candidate solution. To balance exploration and exploitation, SCO is integrated with the two-phase strategy where the candidate solution updates its position differently in each phase. The effectiveness of the proposed approach is validated by testing it on thirty three classical benchmarking functions and four real-world engineering problems. SCO is compared with three well-known optimization algorithms, i.e., Particle Swarm Optimization, Grey Wolf Optimizer, and Gravitational Search Algorithm and with four recent high-performance algorithms: Equilibrium Optimizer, Archimedes Optimization Algorithm, Mayfly Algorithm, and Salp Swarm Algorithm. According to Friedman and Wilcoxon rank-sum tests, SCO can significantly outperform all other algorithms for the majority of the investigated problems. The results achieved by SCO motivates the design and development of new single-solution-based optimization algorithms to further improve the performance. The source code of SCO is publicly available at:https://uk.mathworks.com/matlabcentral/fileexchange/116100-single-candidate-optimizer.
The Nexus between Methods and Power in Sociological Research

Published: August 2022

This article develops an integrative perspective on the nexus between power and sociological research methods. By reflecting upon two of the most widely used methodological approaches in sociology – standardized survey research and qualitative interview research – we develop a comprehensive heuristic framework for examining the ways in which the use of sociological methods affects and intersects any social scientific practice: (1) the power effects that societies and institutional settings exert on methods and the use of methods, (2) power in the use and implementation of methods, and (3) the power effects that methods and the use of methods exert on societies and institutional settings.
Childhood trauma and body dissatisfaction among young adult women: the mediating role of self-criticism

Published: August 2022

The present study examined the relationship between childhood trauma and body dissatisfaction among young women. The mechanisms through which childhood trauma are related to body dissatisfaction have not been sufficiently examined previously. The aims of the present study were to analyze the (i) relationships between childhood trauma, self-criticism, and body dissatisfaction and (ii) mediating role of self-criticism in the relationship between childhood trauma and body dissatisfaction. A total of 754 young adult women aged 18 to 30 years participated (M = 20.49 years; SD = 2.28). The findings showed positive correlations between childhood trauma, self-criticism, and body dissatisfaction. The mediation model indicated that (i) greater childhood trauma was associated with greater self-criticism, and (ii) greater self-criticism was significantly associated with greater body dissatisfaction. Therefore, childhood trauma was indirectly associated with increased body dissatisfaction and explained by the positive relationship with increased self-criticism. These results highlight the importance of childhood trauma in body dissatisfaction among young adult women and demonstrates self-criticism coping style as a key factor in this relationship. Early detection of self-criticism-based coping styles and childhood trauma could improve (i) quality of life and prevent the onset of body dissatisfaction, and (ii) treatment planning and prevent body dissatisfaction from escalating into major problems (e.g., eating disorders, body dysmorphic disorder, morbid exercise and/or depressive symptomatology).
Sibling relationship quality and parental rearing style influence the development of Dark Triad traits

Published: August 2022

Currently our understanding of environmental factors that influence the development of dark personality traits (DT) is limited. Therefore, we conducted three studies using online questionnaires, each examining a different aspect of the relation between dark personality traits and family environment. In Study 1, 117 adults (mean age: 30.36 years, SD = 10.19) filled out questionnaires regarding their childhood relationship with siblings and their own DT traits. We found that the amount of conflicts with siblings during adolescence correlated positively with Machiavellianism and psychopathy. The feeling of closeness towards the siblings showed negative correlation with Machiavellianism. Parental partiality towards the other sibling was positively correlated with narcissism. In Study 2, 111 adolescents (mean age: 15.92, SD = 1.24) reported their perceptions of the rearing style of their parents, in addition to their sibling relationships and DT traits. Perceived parental emotional warmth was negatively associated, whereas both rejection and overprotection were positively correlated with psychopathy. Parental warmth was positively, while rejection negatively associated with narcissism. Machiavellianism was positively associated with the amount of conflicts with siblings, but negatively with closeness to siblings. In Study 3, 110 adults (mean age: 32.62 years, SD = 12.25) reported their levels of the Vulnerable Dark Triad that included measures of primary and secondary psychopathy, maladaptive covert narcissism, and borderline personality organization. Results indicated that sibling relation quality had a significant effect on primary psychopathy and borderline traits. Parental rejection and overprotection correlated with borderline traits and vulnerable narcissism. The results of these studies shed some light on how environmental impulses, particularly the quality of relationships between family members, affect the development of personality.
Development, Diversity and Dynamics of Plant Architecture in Utricularia subgenus Polypompholyx – Towards Understanding Evolutionary Processes in the Lentibulariaceae
Authors: Reut Markus S. , Płachno Bartosz J.
Published: August 2022

To uncover the nature of various kinds of stolons of Utricularia subgenus Polypompholyx (Lentibulariaceae) we studied branching of stolons by scanning electron microscopy, statistically investigated correlations of stolon types and other traits across 56 species, and evaluated seedling development and process morphological aspects. Some results were compared to the sister genera Pinguicula and Genlisea. A key to nine stolon types in Polypompholyx is provided. Predominant stolon types were rhizoids, runner stolons with rhizoids on nodes, and runner stolons without rhizoids on nodes but with bladders on internodes. Stolon types were taxonomically relevant and correlated to the distribution/climate. They obviously diverged with speciation events in Australia. Examined seedlings of Genlisea and Polypompholyx showed similar developmental patterns. Stolons were homologous to traps and leaves. Selected subterranean organs contained specific but similar process combinations of roots, shoots and/or leaves. We assume the Genlisea-Utricularia ancestor trap included processes of a Pinguicula root and leaf.
Alzheimer’s Disease Prediction Using Attention Mechanism with Dual-Phase 18F-Florbetaben Images
Authors: Kang Hyeon , Kang Do-Young
Published: August 2022

Introduction

Amyloid-beta (Aβ) imaging test plays an important role in the early diagnosis and research of biomarkers of Alzheimer’s disease (AD) but a single test may produce Aβ-negative AD or Aβ-positive cognitively normal (CN). In this study, we aimed to distinguish AD from CN with dual-phase 18F-Florbetaben (FBB) via a deep learning–based attention method and evaluate the AD positivity scores compared to late-phase FBB which is currently adopted for AD diagnosis.

Materials and Methods

A total of 264 patients (74 CN and 190 AD), who underwent FBB imaging test and neuropsychological tests, were retrospectively analyzed. Early- and delay-phase FBB images were spatially normalized with an in-house FBB template. The regional standard uptake value ratios were calculated with the cerebellar region as a reference region and used as independent variables that predict the diagnostic label assigned to the raw image.

Results

AD positivity scores estimated from dual-phase FBB showed better accuracy (ACC) and area under the receiver operating characteristic curve (AUROC) for AD detection (ACC: 0.858, AUROC: 0.831) than those from delay phase FBB imaging (ACC: 0.821, AUROC: 0.794). AD positivity score estimated by dual-phase FBB (R: −0.5412) shows a higher correlation with psychological test compared to only dFBB (R: −0.2975). In the relevance analysis, we observed that LSTM uses different time and regions of early-phase FBB for each disease group for AD detection.

Conclusions

These results show that the aggregated model with dual-phase FBB with long short-term memory and attention mechanism can be used to provide a more accurate AD positivity score, which shows a closer association with AD, than the prediction with only a single phase FBB.

Surgery for ileocolonic Crohn’s disease can result in temporary or permanent stoma formation which can be associated with morbidity as parastomal and incisional hernias, readmissions due to obstruction or high stoma output, and have a negative impact on quality of life. We propose an international retrospective trainee-led study of the outcomes of temporary stomas in patients with Crohn’s disease. We aim to evaluate both the short-term (6 month) and mid-term (18 month) outcomes of temporary stomas in patients with Crohn’s Disease. Retrospective, multicentre, observational study including all patients who underwent elective or emergency surgery for ileal, colonic and ileocolonic Crohn’s disease during a 4-year study period. Primary outcome is the proportion of patients who still have an ileostomy or colostomy 18 months after the initial surgery. Secondary outcomes: complications related to stoma formation and stoma reversal surgery; time interval between stoma formation and stoma reversal; risk factors for stoma formation and non-reversal of the stoma. We present the study protocol for a trainee-led, multicentre, observational study. Previous research has demonstrated significant heterogeneity surrounding the formation and the timing of reversal surgery in patients having a temporary ileostomy following colorectal cancer surgery, highlighting the need to address these same questions in Crohn’s disease, which is the aim of our research.

‘Things we are expected to just do and deal with’: Using the medical humanities to encourage reflection on vulnerability and nurture clinical skills, collegiality, compassion, and self-care
Authors: Kelly Michaela , Lynch Johanna , Mainstone Penny , Green Alison , Sturman Nancy
Published: August 2022

The Vulnerability in Medicine (ViM) program was developed to provide protected time and psychologically safe spaces for third-year medical students to consider challenges in the doctor-patient relationship and the clinical workplace. A suite of discussion-prompts presented in a small-group learning environment provides a springboard for students to reflect on their development as clinicians, understand the personhood of their patients, explore the therapeutic relationship, and consider emotional responses and personal, cultural, and social assumptions that impact on care. The program supports students to recognise vulnerability in themselves, the patient, their tutors, and the wider clinical team, as they face the challenge of aligning the clinician they want to become with ideals of professionalism and the imperfect clinical workplace. This 6‑week program focuses on the vulnerability of patients, students, and doctors in a weekly tutorial interposed with clinical placements primarily in geriatric, rehabilitation, or palliative medicine. The tutorials draw from the medical humanities and use experiential, reflective, and narrative learning techniques. They are facilitated by generalist clinicians who model their own vulnerability, humanity, and reflective practice by sharing tutorial tasks equally with students. Students report feeling supported, and appreciate the opportunity to discuss ethical, psychosocial, and emotional aspects of medicine whilst reflecting on what medical practice means to them. Tutors experience a deeper appreciation of student journeys and their own vocations as clinicians and teachers. The sharing of vulnerability exposes the humanity of patients, students, and clinicians, and sustains our whole-person approach to the care of patients, students, and ourselves.
The effect of extended hemodialysis on nutritional parameters: a systematic review
Authors: Majlessi Alireza , Burton James O. , March Daniel S.
Published: August 2022

Objective

This systematic review provides an up-to-date synthesis on the effects of extended hemodialysis on nutritional outcomes.

Design and Methods

Ten databases were searched. Inclusion criteria were: randomised and non-randomised studies of extended hemodialysis (defined by > 15 h/week) with a comparator group which received conventional in-centre hemodialysis (usually ≤ 12 h per week). Outcomes of interest included lean body mass, protein and carbohydrate intake, body mass index, dry lean mass, water-soluble vitamin levels, serum levels of appetite hormones, and nutritional status as assessed by the PEW and SGA scoring tools.

Results

Five studies were eligible. All investigated extended nocturnal hemodialysis (one with the addition of short daily), three were in-centre and two were at home. Range of duration for the included studies was 2–18 months. These studies reported data on lean body mass, protein and carbohydrate intake, body mass index, dry lean mass and water-soluble vitamin levels. There was insufficient homogeneity between the studies to meta-analyse the data. Extended hemodialysis had no significant effects on any of the reported outcomes except for lean body mass, where a significant increase was found, and water-soluble vitamin levels, where deficiency was identified in one of the included studies.

Conclusion

There is currently no evidence to suggest that extended hemodialysis modalities impact nutritional parameters, although the quality of the available evidence is low.

Clouds and aerosols, as well as overhead ozone, can have large effects on ultraviolet (UV) irradiances. We use statistical methods to remove cloud effects and mean aerosol effects from spectral UV irradiance measurements to investigate the relationship between UV and total column ozone. We show that for fixed solar zenith angles (SZA), seasonal changes in ozone lead to marked changes in clear-sky UV irradiances. Such effects are larger at mid-latitudes than in the tropics. At mid-latitudes, the minimum ozone amount over the course of a year can be about 50 percent of its maximum, with the lowest values in autumn and the highest values in spring. These seasonal ozone changes lead to UV Index (UVI) values in autumn that can exceed those in spring at the same SZA by nearly a factor of two. Differences are even larger for UV spectra weighted by the action spectra for DNA-damaging UV, and for cutaneous previtamin D production. In some cases, the seasonal increase exceeds a factor of 4. The analysis experimentally demonstrates the limits of applicability of the concept of constant Radiative Amplification Factors (RAFs) for estimating effects of changes in ozone for some weighting functions. Changes in DNA-weighted UV and erythemally weighted UV are well represented by the published RAFs. However, there are large SZA dependencies in the case of UVB and vitamin D-weighted UV. For all weightings considered, RAFs calculated from the observations as a function of SZA show similar dependencies between sites, in good agreement with published values, independently of the ozone data source.

Subaltern Frontiers
Authors: Cowan Thomas
Published: August 2022

In urban and peri-urban areas across the Global South, politicians, planners and developers are engaged in a voracious scramble to refashion land for global real estate investment, and transfer state power to private sector actors. Much of this development has taken place on the outskirts of the traditional metropoles, in the territorially flexible urban frontier. At the forefront of these processes in India, is Gurgaon, a privately developed metropolis on the south-western hinterlands of New Delhi, that has long been touted as India's flagship neoliberal city. Subaltern Frontiers tells a story of India's remarkable urban transformation by examining the politics of land and labour that have shaped the city of Gurgaon. The book examines how the country's flagship post-liberalisation urban project has been shaped and filtered through agrarian and subaltern histories, logics, and subjects. In doing so, the book explores how the production of globalised property and labour in contemporary urban India is filtered through colonial instruments of land governance, living histories of uneven agrarian development, material geographies of labour migration, and the worldly aspirations of peasant-agriculturalists.
In the Middle: American Multinationals in China and Trade War Politics

Which factors make some American multinational corporations (MNCs) take political action in response to the US–China Trade War and cause others to stay on the sidelines? We identify China-based subsidiaries of US firms to identify firms’ political actions in response to the trade war. We combine data on firms’ tariff exposure, economic actions in China, and political actions in the United States during the trade war. Together these data highlight the divergent strategies with which firms engage. Even though more than 63 percent of MNCs in our sample were adversely impacted by tariffs, only 22 percent voice opposition and 7 percent exit in response to the trade war. Our analysis reveals that US MNCs in China differ in their business models, ownership structure, experience in China, and size of capital investments. These firm-level factors determine the degree to which US MNCs are embedded in China. This in turn shapes how firms perceive political risk and choose from the menu of options to deal with the trade war. Size and age increase voice while joint-venture status decreases it.
Baroclinic tidal conversion: note on a paper of L.R.M. Maas
Authors: Wunsch Carl , Wunsch Jared
Published: August 2022

Maas (J. Fluid Mech., vol. 684, 2011, pp. 5–24) showed that, for an oscillating two-dimensional barotropic tide flowing over sub-critical topography of compact support, some topographic forms existed that produced non-radiating baroclinic disturbances. The problem is related to ‘stealth’ and ‘cloaking’ problems. Here Maas's result is derived using a simpler approach, not involving complicated mappings, but formally restricted to perturbation topography. Wider results come from the discussion of nearly compact support topographic disturbances provided by Schwartz functions with weak high-wavenumber radiation and by exploiting both a known functional equation formulation and Fourier methods. The problem is extended to disturbances on uniform slopes. A variety of non-radiating topographies can be found, although they are mathematically delicate and unlikely to be found in nature. Topography with weak radiation at high wavenumber is a much wider class of structures. Application of these solutions would lie with the ability to estimate dissipation over and near the topography from motions observed at a distance.
Streamwise inclination angle of wall-attached eddies in turbulent channel flows
Authors: Cheng Cheng , Shyy Wei , Fu Lin
Published: August 2022

We develop a new methodology to assess the streamwise inclination angles (SIAs) of the wall-attached eddies populating the logarithmic region with a given wall-normal height. To remove the influences originating from other scales on the SIA estimated via two-point correlation, the footprints of the targeted eddies in the vicinity of the wall and the corresponding streamwise velocity fluctuations carried by them are isolated simultaneously, by coupling the spectral stochastic estimation with the attached-eddy hypothesis. Datasets produced with direct numerical simulations spanning

$Re_{\tau } \sim O(10^2)\unicode{x2013}O(10^3)$

are dissected to study the Reynolds number effect. The present results show, for the first time, that the SIAs of attached eddies are Reynolds-number-dependent in low and medium Reynolds numbers, and tend to saturate at

$45^{\circ }$

as the Reynolds number increases. The mean SIA reported by vast previous experimental studies are demonstrated to be the outcomes of the additive effect contributed by multi-scale attached eddies. These findings clarify the long-term debate and perfect the picture of the attached-eddy model.
