Current landscape of research ethics consultation services: National survey results
Authors: Taylor Holly A. , Porter Kathryn M. , Sullivan Connor , McCormick Jennifer B. 
Published: November 2022

Abstract

Introduction:
The goal of a research ethics consultation service (RECS) is to assist relevant parties in navigating the ethical issues they encounter in conduct of research. The goal of this survey was to describe the current landscape of research ethics consultation and document if and how it has changed over the last decade.

Methods:
The survey instrument was based on the survey previously circulated. We included a number of survey domains from the previous survey with the goal of direct comparison of outcomes. The survey was sent to 57 RECS in the USA and Canada.

Results:
Forty-nine surveys were completed for an overall response rate of 86%. With the passing of 10 years, the volume of consults received by RECS surveyed has increased. The number of consults received by a subset of RECS remains low. RECS continues to receive requests for consults from a wide range of stakeholders. About a quarter of RECS surveyed actively evaluate their services, primarily through satisfaction surveys routinely shared with requestors. The number of RECS evaluating their services has increased. We identified a group of eight key competencies respondents find as key to providing RECS.

Conclusions:
The findings from our survey demonstrate that there have been growth and development of RECS since 2010. Further developing evaluation and competency guidelines will help existing RECS continue to grow and facilitate newly established RECS maturation. Both will allow RECS personnel to better serve their institutions and add value to the research conducted.
Roles of TGF-β in cancer hallmarks and emerging onco-therapeutic design
Authors: Dai Xiaofeng , Hua Dong , Lu Xiaoxia 
Published: November 2022

Abstract
Transforming growth factor-beta (TGF-β) is a double-edged sword in cancer treatment because of its pivotal yet complex and roles played during cancer initiation/development. Current anti-cancer strategies involving TGF-β largely view TGF-β as an onco-therapeutic target that not only substantially hinders its full utilisation for cancer control, but also considerably restricts innovations in this field. Thereby, how to take advantages of therapeutically favourable properties of TGF-β for cancer management represents an interesting and less investigated problem. Here, by categorising cancer hallmarks into four critical transition events and one enabling characteristic controlling cancer initiation and progression, and delineating TGF-β complexities according to these cancer traits, we identify the suppressive role of TGF-β in tumour initiation and early-stage progression and its promotive functionalities in cancer metastasis as well as other cancer hallmarks. We also propose the feasibility and possible scenarios of combining cold atmospheric plasma (CAP) with onco-therapeutics utilising TGF-β for cancer control given the intrinsic properties of CAP against cancer hallmarks.
Critical recurrence in the real quadratic family
Authors: BYLUND MATS 
Published: November 2022

AbstractWe study recurrence in the real quadratic family and give a sufficient condition on the recurrence rate$(\delta _n)$of the critical orbit such that, for almost every non-regular parametera, the set ofnsuch that$\vert F^n(0;a) \vert < \delta _n$is infinite. In particular, when$\delta _n = n^{-1}$, this extends an earlier result by Avila and Moreira [Statistical properties of unimodal maps: the quadratic family.Ann. of Math. (2)161(2) (2005), 831–881].
First photometric and orbital period investigations of four W UMa-type eclipse binaries

Published: November 2022

AbstractWe presented the first photometric and orbital period investigations for four W Ursae Majoris-type binaries: V473 And, V805 And, LQ Com, and EG CVn. The photometric solutions suggested that V805 And and LQ Com are two total-eclipse contact binaries, while V473 And and EG CVn are partial-eclipse ones. V473 And and LQ Com belong to the A-subtype contact binaries, while V805 And and EG CVn belong to the W subtype. The O’Connell effects found in the light curves of V805 And, LQ Com, and EG CVn can be interpreted as a result of a cool spot on the surface of their less massive and hotter primary components. Based on two different methods, the absolute physical parameters were properly determined. Combining the eclipse timings derived from our observations and survey’s data with those collected from literature, we investigated their orbital period variations. The results show that the orbital periods of V473 And, V805 And, and EG CVn are undergoing a secular decrease/increase superposed a periodic variation, while LQ Com exhibits a possible cyclic period variation with a small amplitude. The secular period changes are caused mainly by the mass transfer between two components, while the cyclic period oscillations may be interpreted as the results of either the light-time effect due to the third body or the cyclic magnetic activity. Finally, we made a statistical investigation for nearly 200 contact binaries with reliable physical parameters. The statistical results suggested that the W-subtype systems are more evolved than the A-subtype ones. Furthermore, the evolutionary direction of A-subtype into W-subtype systems is also discussed. The opposite evolutionary direction seems to be unlikely because it requires an increase of the total mass, the orbital angular momentum, and the temperature differences between two components of a binary system.
SOCIETY IN TRANSITION: CULTURAL CHANGE IN THE EARLY BRONZE AGE CEMETERY AT NIŽNÁ MYŠL’A IN THE LIGHT OF ABSOLUTE CHRONOLOGY
Authors: Jaeger Mateusz , Stróżyk Mateusz , Olexa Ladislav 
Published: November 2022

ABSTRACTThe article presents the results of research on the absolute chronology of the Nižná Myšľa cemetery. Due to its scale and location in a key region of the Carpathian Basin, it should be considered one of the most important Early Bronze Age sites in Central Europe. Many years of archaeological research have so far failed to provide adequate data on absolute chronology. This text presents the results of statistical and spatial analyses on a series of newly acquired 14C dates. They allowed us to present a model of the spatial and chronological development of the funerary space and to capture the stage of significant cultural change associated with the adoption of a new raw material—bronze.
-ALGEBRAS OF SELF-SIMILAR ACTION OF GROUPOIDS ON ROW-FINITE DIRECTED GRAPHS

AbstractFor amenable discrete groupoids

and row-finite directed graphs E, let
$(\mathcal {G},E)$
be a self-similar groupoid and let
$C^*(\mathcal {G}, E)$
be the associated
$C^*$
-algebra. We introduce a weaker faithfulness condition than those in the existing literature that still guarantees that
$C^*(\mathcal {G})$
embeds in
$C^*(\mathcal {G}, E)$
. Under this faithfulness condition, we prove a gauge-invariant uniqueness theorem.
AN AMAZING IDENTITY OF GAUSS AND JENKINS’ LEMMA
Authors: CHAN HENG HUAT , CHAN SONG HENG 
Published: November 2022

AbstractWe prove several finite product-sum identities involving the q-binomial coefficient, one of which is used to prove an amazing identity of Gauss. We then use this identity to evaluate certain quadratic Gauss sums and, together with known properties of quadratic Gauss sums, we prove the quadratic reciprocity law for the Jacobi symbol. We end our article with a new proof of Jenkins’ lemma, a lemma analogous to Gauss’ lemma. This article aims to show that Gauss’ amazing identity and the properties of quadratic Gauss sums are sufficient to establish the quadratic reciprocity law for the Jacobi symbol.
Defining Victimhood: The Political Construction of a “Victim” Category in Colombia’s Congress, 2007–2011
Authors: Foringer Kristin 
Published: November 2022

AbstractScholars of state classification practices have long interrogated how official legal categories are constructed. This paper analyzes the construction of “victimhood” in Colombia as a feat that required negotiation among international human rights organizations, local civil society actors, and politicians across the partisan spectrum. The Victims’ Law of 2011, which sought to provide widespread reparations to victims of the civil conflict, originated from the concerns of the human rights community, yet the deliberation process leading up to the law’s passage reveals the extent to which elite historical narratives of the conflict unduly narrowed the universe of eligible victims. Using archival evidence from congressional debates from 2007 to 2011, this paper argues that the broad conception of victimhood originally inherited from United Nations guidelines came to be constrained by disproportionate influence from politicians’ personal understandings of conflict history, shaped by anecdote and the selective use of historical evidence. These rationales interacted with budgetary constraints to ultimately restrict the victim category according to negotiated temporal boundaries of the conflict.
Childhood, Love and Politics: The Montonero ‘Nursery’ in Cuba during the Cold War
Authors: Cosse Isabella 
Published: November 2022

AbstractThis article examines the conditions that led the Argentine armed group Montoneros to establish a nursery in Cuba, in 1979, to care for the children of exiled members who had decided to return to the country to fight against a dictatorial regime characterised by the crime of enforced disappearance and supported by continental and global alliances. The analysis focuses on the dilemmas children posed for militants and the organisation and how those concerns were in part addressed by setting up a facility to care for the children. The article then considers how that childcare effort by the Montoneros connected with Cuba's internationalist and refugee policies and with continental struggles, as well as looking at how the children involved experienced it. This reconstruction offers a new approach to thinking about political conflicts in the heated Cold War scenario in Latin America, through the lens of children's history and by exploring how love and politics are intertwined.

Published: November 2022

AbstractBackgroundResearch suggests that there have been inequalities in the impact of the coronavirus disease 2019 (COVID-19) pandemic and related non-pharmaceutical interventions on population mental health. We explored generational, sex, and socioeconomic inequalities during the first year of the pandemic using nationally representative cohorts from the UK.MethodsWe analysed data from 26772 participants from five longitudinal cohorts representing generations born between 1946 and 2000, collected in May 2020, September–October 2020, and February–March 2021 across all five cohorts. We used a multilevel growth curve modelling approach to investigate generational, sex, and socioeconomic differences in levels of anxiety and depressive symptomatology, loneliness, and life satisfaction (LS) over time.ResultsYounger generations had worse levels of mental and social wellbeing throughout the first year of the pandemic. Whereas these generational inequalities narrowed between the first and last observation periods for LS [−0.33 (95% CI −0.51 to −0.15)], they became larger for anxiety [0.22 (0.10, 0.33)]. Generational inequalities in depression and loneliness did not change between the first and last observation periods, but initial depression levels of the youngest cohort were worse than expected if the generational inequalities had not accelerated. Women and those experiencing financial difficulties had worse initial mental and social wellbeing levels than men and those financially living comfortably, respectively, and these gaps did not substantially differ between the first and last observation periods.ConclusionsBy March 2021, mental and social wellbeing inequalities persisted in the UK adult population. Pre-existing generational inequalities may have been exacerbated with the pandemic onset. Policies aimed at protecting vulnerable groups are needed.

Abstract
To reappraise pre-exposure prophylaxis (PrEP) eligibility criteria towards the men who have sex with men (MSM) with highest HIV-risk, we assessed PrEP need (i.e. HIV-risk) using Amsterdam Cohort Studies data from 2011–2017 for all non-PrEP using MSM. Outcomes were incident HIV-infection and newly-diagnosed anal STI. Determinants were current PrEP eligibility criteria (anal STI and condomless sex (CAS)) and additional determinants (age, education, group sex, alcohol use during sex and chemsex). We used targeted maximum likelihood estimation (TMLE) to estimate the relative risk (RR) and 95% confidence intervals (CI) of determinants on outcomes, and calculated population attributable fractions (PAFs) with 95% CI using RRs from TMLE. Among 810 included MSM, 22 HIV-infections and 436 anal STIs (n = 229) were diagnosed during follow-up. Chemsex (RR = 5.8 (95% CI 2.0–17.0); PAF = 55.3% (95% CI 43.3–83.4)), CAS with a casual partner (RR = 3.3 (95% CI 1.3–8.7); PAF = 38.0% (95% CI 18.3–93.6)) and anal STI (RR = 5.3 (95% CI 1.7–16.7); PAF = 22.0 (95% CI −16.8 to 100.0)) were significantly (P < 0.05) associated with and had highest attributable risk fractions for HIV. Chemsex (RR = 2.0 (95% CI 1.6–2.4); PAF = 19.5 (95% CI 10.6–30.6)) and CAS with a casual partner (RR = 2.5 (95% CI 2.0–3.0); PAF = 28.0 (95% CI 21.0–36.4)) were also significantly associated with anal STI, as was younger age (16–34/≥35; RR = 1.7 (95% CI 1.4–2.1); PAF = 15.5 (95% CI 6.4–27.6)) and group sex (RR = 1.3 (95% CI 1.1–1.6); PAF = 9.0 (95% CI −2.3 to 23.7)). Chemsex should be an additional PrEP eligibility criterion.
Mother and child mental health over time in children with Autism and/or ADHD in the Longitudinal Study of Australian Children
Authors: May Tamara , Williams Katrina 
Published: November 2022

AbstractThis study utilised a longitudinal population-based study to explore mother and child mental health trajectories over time from child age 0 to 14 years, between children with ASD, ADHD, or ASD + ADHD. It explored whether a bidirectional relationship between mother psychological distress and child emotional and behavioural problems (EBPs) existed. The birth cohort from the Longitudinal Study of Australian Children was used. Child EBPs were assessed using the Strengths and Difficulties Questionnaire; and mother emotional distress using the Kessler K6. Generalised estimating equations and structured equation modelling was used to understand changes over time, differences between groups and bidirectional relationships. As expected, children with ASD, ADHD or ASD + ADHD had higher EBPs than children without, and their mothers had higher levels of psychological distress across most time points, but with differing trajectories. Mothers of children with ASD (with or without ADHD) showed increasing psychological distress over time, while mothers of children with ADHD had reducing distress. The bidirectional relationship between mother and child mental health found in children without diagnoses was only partially present in children with ASD/ADHD. Findings highlight support needs and discuss implications for transactional models of parent/child emotional problems in children with neurodevelopmental disorders.
Neural activation, cognitive control, and attention deficit hyperactivity disorder: Evaluating three competing etiological models
Authors: Peisch Virginia , Arnett Anne B. 
Published: November 2022

AbstractBackground:Cognitive control impairments are observed across several psychiatric conditions, highlighting their role as a transdiagnostic marker. Individuals with attention deficit hyperactivity disorder (ADHD) have difficulties with inhibition, working memory, processing speed, and attention regulation. These cognitive control impairments may either mediate or moderate the association between neurobiological vulnerabilities and phenotypic presentation in neurodevelopmental disorders. Alternately, neurocognitive vulnerabilities in ADHD may be additive, akin to a multiple deficit model. We tested the mediation, moderation, and additive models using neurocognitive data in youth with ADHD.Methods:7–11 year-old children diagnosed with ADHD (n = 75) and control children (n = 29) completed EEG recordings and neuropsychological testing (full scale IQ; cognitive control). Caregivers provided ADHD symptom ratings. Correlations and linear regression analyses were completed to examine the associations among cortical functioning (aperiodic slope), cognitive control, and ADHD symptoms.Results:We found support for an additive model wherein vulnerabilities in aperiodic slope, event-related potentials, and cognitive control each explained unique variance in ADHD symptoms. There was some evidence that cognitive control moderates the effect of atypical cortical development on ADHD symptoms. There was no support for the mediation model.Conclusions:The etiology of ADHD symptoms is multifaceted and involves multiple “hits” across neurological and cognitive-behavioral factors.
Institutional resilience: how the formal legal system sustains informal cooperation
Authors: Buchen Clemens 
Published: November 2022

Abstract
This paper introduces the concept of institutional resilience based on a population game. Agents in an economy are randomly matched to play a coordination game with two strategies, cooperate and defect. A breach of contract can be adjudicated in court. Agents can update their strategy, which is modelled using the replicator dynamic. In this context, cooperation is defined as the informal institution, whereas the legal system (contract law) constitutes the formal institution. Institutional resilience is defined by how the formal institution of a functioning legal system complements the informal institution of cooperation in a dynamic way. In the wake of an adverse exogenous shock, the formal institution can prevent a total breakdown of cooperation in the population.
Design and analysis of broadband circularly polarized compact planar antennas for 2.45 GHz RFID handheld reader applications
Authors: Agrawal Niraj , Gautam Anil Kumar , Rambabu Karumudi 
Published: November 2022

AbstractIn this article, an innovative design of a broadband circularly polarized compact planar antenna for RFID (radio frequency identification) receivers is presented. The suggested structure used the concept of slots loaded parasitic element printed underneath a coplanar waveguide-fed radiator to achieve the circularly polarized (CP) radiation and size reduction. A parasitic element loaded with F-slot and L-slot, and a window-type slotted ground plane was used to achieve resonance at 2.45 GHz with right-handed circularly polarized radiation for RFID handheld reader application. Experimental results confirmed that the designed antenna of size 16.5 × 14.8 × 1.6 mm3 attained a −10 dB impedance bandwidth of 15.8% (from 2.330 to 2.716 GHz) and 3 dB AR bandwidth of 3.43% (from 2.410 to 2.494 GHz). An axial ratio of 0.43 dB was achieved in the boresight of the antenna at the 2.45 GHz RFID band. The concept of electric field distribution on the antenna was used to elaborate the excitation of CP radiation in the antenna.
Human activities and zoonotic epidemics: a two-way relationship. The case of the COVID-19 pandemic
Authors: Tounta Despoina D. , Nastos Panagiotis T. , Tesseromatis Christine 
Published: November 2022

Non-technical summaryHumans have the tendency to damage the natural environment in many ways. Deforestation and conversion of forests for residential, industrial development, and expansion of agricultural crops, as well as the burning of fossil fuels, are some activities that disrupt natural ecosystems and wildlife and contribute to climate change. As a result, the life cycles of pathogens and intermediate hosts (insects, rodents, mammals) as well as biodiversity are affected. Through these activities, humans meet wild animals that transmit pathogens, resulting in their infection by zoonoses and causing epidemics–pandemics, the effects of which have as their final recipient himself and his activities.Technical summaryThis article aims to highlight the two-way relationship between those human activities and the occurrence of epidemics–pandemics. We will try to elaborate this two-way relationship, through the overview of the current pandemic (origin of SARS-CoV-2, modes of transmission, clinical picture of the disease of COVID-19, influence of weather and air pollution on prevalence and mortality, pandemic effects, and treatments). They are used as primary sources, scientific articles, literature, websites, and databases (Supplementary appendix) to analyze factors involved in the occurrence and transmission of zoonotic diseases in humans (Ebola, influenza, Lyme disease, dengue fever, cholera, AIDS/HIV, SARS-CoV, MERS-CoV). The present paper concluded that humanity today faces two major challenges: controlling the COVID-19 pandemic and minimizing the risk of a new global health crisis occurring in the future. The first can be achieved through equitable access to vaccines and treatments for all people. The second needs the global community to make a great change and start protecting the natural environment and its ecosystems through the adoption of prevention policies.Summary of social mediaTwo-way relationship between human activities and epidemics highlighted, through review of the COVID-19 pandemic.
Spatial Microbial Respiration Variations in the Hyporheic Zones Within the Columbia River Basin

Published: November 2022

AbstractWhile the hyporheic zone (HZ) accounts for a significant portion of whole stream CO2 concentrations, HZ respiration modeling studies are lacking in quantifying their contributions to the total CO2 at large watershed/basin scales. Quantifying the contribution of anaerobic respiration is also underappreciated. This study used a carbon‐nitrogen‐coupled river corridor model to quantify HZ aerobic and anaerobic respiration and determined the key factors controlling their spatial variability within the Columbia River Basin (CRB). The modeled respiration patterns showed high spatial variability. Among the nine sub‐basins composing the CRB, the Lower Columbia and the Willamette, which receive higher precipitation, had higher respiration. Medium‐sized rivers (fourth to sixth orders) produced the highest aerobic and anaerobic respiration among reaches of different sizes. At the basin scale, aerobic respiration is dominant, representing approximately 98.7% of the total respiration across the CRB. While most of the reaches were dominant with aerobic respiration, reaches in agricultural land showed a relatively higher anaerobic respiration (18%) ratio. A variable importance analysis showed that hyporheic exchange flux controlled most of the spatial variability of HZ respiration, dominating over other physical variables such as residence time, stream dissolved organic carbon (DOC), nitrate, and dissolved oxygen (DO). The influence of substrate concentration (DOC and DO) is larger in modeling anaerobic respiration than aerobic respiration. Future efforts will focus on improving the estimation of the HZ exchange flux and the implementation of spatially explicit parameterizations for the reactions of interest to reduce model uncertainty.
