Mothers stick together: how the death of an infant affects female social relationships in a group of wild bonobos (Pan paniscus)
Authors: Cheng Leveda , Shaw Amber , Surbeck Martin 
Published: April 2022

AbstractSociality is widespread among group-living primates and is beneficial in many ways. Sociality amongst female bonobos (Pan paniscus) has been proposed to have evolved as a female counterstrategy to male infanticide and sexual coercion. In male-philopatric bonobo societies, females mostly form relationships with unrelated females. Among these social relationships, it has been proposed that females with infants (also referred to as mothers) tend to have strong relationships with each other (mother-bonding hypothesis). In this paper, we use the case of an infant death in a group of wild bonobos in the Kokolopori Bonobo Reserve, Democratic Republic of Congo, to test this hypothesis. By using dyadic sociality indices for grooming, proximity, and aggression, we investigated whether the infant death influenced dyadic relationships the mother had with other group members. Before the infant death, grooming index (GI) and proximity index (PI) scores were the highest between the focal mother and another mother. After the death, the relationship of this mother dyad weakened, as indicated by lower GI and PI scores, whereas the relationship of another mother dyad became stronger. Aggression index scores among the mothers were comparable before and after the death, suggesting that changes in mother affiliative relationships were not a by-product of changes in overall interaction frequencies. Also, PI scores increased between the focal mother and three non-mothers after the death. Collectively, the shift in social dynamics between the focal mother and other group members after the infant death partially supported the mother-bonding hypothesis.

Abstract
Astaxanthin (AX) is one of the commonly used feed supplements to enhance the growth performance and provide antioxidant and immune functions of several aquatic animals. In the current study, juveniles of white-leg shrimp (Litopenaeus vannamei) with mean initial weight of 0.340 ± 0.041 g were fed with diets supplemented with 0 (control), 25, 50, 100, and 200 mg/kg feed for 8 weeks. At the end of the feeding trial, shrimps were exposed to Vibrio harveyi, and their mortality rates were observed for additional 10 days. The growth indices in the AX-fed groups were significantly (P < 0.05) higher than what were observed in shrimps in the control group. Dietary AX stimulated the final weight, weight gain, and specific growth rate and optimum growth levels were achieved at 100–200 mg AX/kg feed. Furthermore, the AX-enriched diets significantly enhanced feed intake more than the control diet, and the amount of AX had no effects on feed conversion ratios. In comparison to the control group, the AX-fed animals had significantly (P < 0.05) higher villi length, villi width, and absorption area and their optimum values were observed at 100–200 mg AX/kg feed treatments. Moreover, the intestinal morphometry especially villi and its crypt, both internal and external tunica muscularis, and submucosal tissues did not show any inflammatory and/or degenerative changes in AX-fed shrimp. Furthermore, the dietary AX at escalating levels linearly and quadratically enhanced (P < 0.05) the activities of serum superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and increased levels of total antioxidant capacity and reduced glutathione. In addition, malondialdehyde levels decreased significantly in AX-fed animals, and the highest levels were observed in the control group (without AX). The expression levels of cMn-SOD, CAT, and GPx genes were significantly upregulated in the hepatopancreas of L. vannamei fed with AX-enriched diets (especially in the 200-mg/kg feed treatment) as compared with the control diet. The immunity indices of the AX treatments (hematocyte count, total protein, lysozyme, phagocytic activity, and phenoloxidase) of L. vannamei were linearly (P < 0.05) and quadratically (P < 0.05) increased. This study revealed the antibacterial activity of AX against V. harveyi abundance. After the bacterial challenge, feeding L. vannamei with dietary AX significantly increased (P < 0.05) the relative percentage of survival, especially in the treatment of 200-mg/kg diet (82.7%). The findings of the current study demonstrate that dietary AX (100–200 mg/kg feed) was effective in enhancing the growth, antioxidant status, immune response, and increasing the resistance of L. vannamei against V. harveyi infection.
Shortcomings in the Operation and Coordination of Witness Protection in Australia. Where to from Here?
Authors: Monterosso Stephen 
Published: April 2022

AbstractWitness protection in Australia has, to date, been less than successful in implementation and execution. An ad hoc system of Commonwealth and state/territory witness protection programs have co-existed with often substandard outcomes for participants, law enforcement and the criminal justice system. Although in accordance with Australia’s federal system of government, the framework of witness protection that has emerged has resulted in numerous witness protection programs in operation across states and territories with little in the way of consistency, cooperation and coordination. Reform in Australia’s witness protection system is needed to improve and streamline programs for the benefit of witnesses, communities and the criminal justice system. This article addresses shortcomings and draws attention to worthwhile changes that would benefit and enhance domestic witness protection.
Can There be a Process Without Time? Processualism Within Timeless Physics
Authors: Margoni Emilia 
Published: April 2022

AbstractProcess ontology is making deep inroads into the hard sciences. For it offers a workable understanding of dynamic phenomena which sits well with inquiries that problematize the traditional conception of self-standing, definite, independent objects as the basic stuff of the universe. Process-based approaches are claimed by their advocates to yield better ontological descriptions of various domains of physical reality in which dynamical, indefinite activities are prior to definite “things” or “states of things”. However, if applied to physics, a main problem comes up: the notion itself of process appears to pivot on a conception of evolution through time that is at variance with relativistic physics. Against this worry, this article advances a conception of process that can be reconciled with general relativity. It claims that, within timeless physical frameworks, a process should not be conceived as activities evolving through time. Rather, processes concern the identity that entities obtain within the broader sets of relations in which they stand. To make this case, the article homes in on one of the physical approaches that most resolutely removes time from the basic features of reality, that is, canonical quantum gravity. As a case in point, it addresses Carlo Rovelli’s Evolving Constant approach as a physical paradigm that resolutely rejects time as an absolute parameter and recasts processualism as an inquiry into how physical systems affect one another.

AbstractBetween the years of 2003–2015, the Programme for International Student Assessment (PISA) has identified a global trend signalling a decline in a sense of school belonging for secondary school students. Research has identified several factors that are positively related to school belonging, such as teacher support and academic motivation. However, little empirical research has been conducted to evaluate the relevant school belonging variables holistically and to assess their socio-ecological levels (e.g., student, microsystem, mesosystem) relative to the student. The purpose of this study is to assess the significant predictive variables within each socio-ecological level regarding school belonging. For this purpose, this study used data collected by PISA in 2015, focusing on data from 309,785 15-year-old students attending 12,668 schools in 52 countries around the world. Hierarchical multiple regression analysis was conducted to a) examine the empirical support for a layered structure of sense of school belonging, b) explore the contributions of variables in each layer of the socio-ecosystem to explain the variability in sense of school belonging and c) examine potential variations in this ability across schools and countries. The models provided support for the existence of such layers but also for some underlying relationships across the variables in the layers of the socio-ecosystem. The study then concludes with a discussion of the implications of the findings for school leaders, teachers and parents with respect to how school belonging approaches and strategies can be absorbed into existing practices and operations at school.
Trajectories of Change in Parental Self-Esteem and Emotion Regulation from Pregnancy until 4 Years Postpartum

Published: April 2022

AbstractWe know a great deal about the immediate impact of becoming a parent, but less on the more long-term impact as parents are adapting to the rapid developmental changes that characterize the early childhood period. This longitudinal study explored how parental self-esteem and emotion regulation develops during pregnancy, infancy, toddlerhood and preschool-age. We used nine waves of data from 550 Dutch fathers and mothers to examine stability and change in self-esteem and emotion regulation from pregnancy until 4 years postpartum, for both first and later pregnancies. Self-esteem and emotion regulation showed the same trajectory of change, with decreases during pregnancy and infancy, and increases during toddlerhood and preschool-age. Fathers had higher mean-levels of self-esteem and emotion regulation than mothers, but child age-related changes were the same for fathers and mothers. First-time parents and second-, third-, or fourth-time parents did not differ in mean-level self-esteem and emotion regulation, nor in age-related change. Over the course of 4 years postpartum, parents slightly increased in self-esteem and emotion regulation. The results suggest that, for the average parent, the birth of a child causes a temporary deviation from the overall trend toward greater self-esteem and emotion regulation. Since both traits are predictive for parental well-being, positive parenting and child development, future research needs to investigate if an intervention should and could ease the transition to parenthood and thereby prevent this decline.

AbstractParenting self-regulation is increasingly recognised as an important facet of positive parenting, as it allows parents to manage their thoughts, behaviours, emotions and attention in order to effectively carry out parenting tasks. Evidence-based parenting programmes such as the Triple P-Positive Parenting Program aim to increase parenting self-regulation by teaching parents a range of skills and strategies to deal with everyday parenting. Despite the importance of self-regulation within the field of parenting, few measures assessing this construct are available. The current investigation aims to add to existing literature by evaluating the measurement properties of a brief and parsimonious measure of self-regulation for both parents and parenting practitioners, the Parenting Self-Regulation Scales (PSRS)—Parent and Practitioner versions. Exploratory and Confirmatory Factor Analyses gave support for a single-factor model for the parent version, and this was confirmed in the practitioner version. Both versions demonstrated excellent internal consistency and hypothesis testing supported the construct validity of both scales. The results indicate that the PSRS is a promising brief measure of parenting self-regulation for parents and practitioners which could prove useful to both clinical work and research in the parenting field.
Second Order Splitting Dynamics with Vanishing Damping for Additively Structured Monotone Inclusions
Authors: Boţ Radu Ioan , Hulett David Alexander 
Published: April 2022

AbstractIn the framework of a real Hilbert space, we address the problem of finding the zeros of the sum of a maximally monotone operator A and a cocoercive operator B. We study the asymptotic behaviour of the trajectories generated by a second order equation with vanishing damping, attached to this problem, and governed by a time-dependent forward–backward-type operator. This is a splitting system, as it only requires forward evaluations of B and backward evaluations of A. A proper tuning of the system parameters ensures the weak convergence of the trajectories to the set of zeros of $$A + B$$

, as well as fast convergence of the velocities towards zero. A particular case of our system allows to derive fast convergence rates for the problem of minimizing the sum of a proper, convex and lower semicontinuous function and a smooth and convex function with Lipschitz continuous gradient. We illustrate the theoretical outcomes by numerical experiments.

AbstractReflection and critically refracted seismic methods use traveltime measurements of body waves propagating between a source and a series of receivers on the ground surface to calculate subsurface velocities. Body wave energy is refracted or reflected at boundaries where there is a change in seismic impedance, defined as the product of material density and seismic velocity. This article provides practical guidance on the use of horizontally propagating shear wave (SH-wave) refraction and reflection methods to determine shear wave velocity as a function of depth for near-surface seismic site characterizations. Method principles and the current state of engineering practice are reviewed, along with discussions of limitations and uncertainty assessments. Typical data collection procedures are described using basic survey equipment, along with information on more advanced applications and emerging technologies. Eight case studies provide examples of the techniques in real-world seismic site characterizations performed in a variety of geological settings.
Analysis of the Football Transfer Market Network
Authors: Wand Tobias 
Published: April 2022

AbstractUsing publicly available data from the football database transfermarkt.co.uk, it is possible to construct a trade network between football clubs. This work regards the network of the flow of transfer fees between European top league clubs from eight countries between 1992 and 2020 to analyse the network of each year’s transfer market. With the transfer fees as weights, the market can be represented as a weighted network in addition to the classic binary network approach. This opens up the possibility to study various topological quantities of the network, such as the degree and disparity distributions, the small-world property and different clustering measures. This article shows that these quantities stayed rather constant during the almost three decades of transfer market activity, even despite massive changes in the overall market volume.
Stability, Autonomy, and the Foundations of Political Liberalism
Authors: Taylor Anthony 
Published: April 2022

AbstractAn attractive form of social stability is realized when the members of a well-ordered society give that society’s organizing principles their free and reflective endorsement. However, many political philosophers are skeptical that there is any requirement to show that their principles would engender this kind of stability. This skepticism is at the root of a number of objections to political liberalism, since arguments for political liberalism often appeal to its ability to be stable in this way. The aim of this paper is to address skepticism about the stability condition by putting forward a novel defense of it. My defense builds on the claim that stable principles are necessary to secure the full autonomy of those who live under them.

Published: April 2022

Abstract
Background
Child-rearing isolation may increase the risk of child abuse and negatively affect child development owing to increased urbanization and a decline in family and community support systems.

Purpose
This study aimed to identify the prevalence of child-rearing isolation and the related sociodemographic factors among mothers in Japan using data from the Final Survey of Healthy Parents and Children 21.

Participants
Mothers of young children attending their health checkups.

Methods
Multivariate logistic regression models assessed the association between child-rearing isolation and socio-demographic variables. Data from 69,337 women were analyzed.

Results
Mothers who experienced child-rearing isolation comprised 0.2% of all participants. Mothers who were 35 to 39 years old at childbirth (OR = 1.6, CI[1.0, 2.4], p = .036), were unemployed (OR = 1.7, CI[1.3, 2.4], p = .001), had experienced financial difficulty (OR = 1.8, CI[1.3, 2.5], p < .001), had husbands with limited participation in child-rearing (OR = 5.7, CI[4.2, 7.9], p < .001), lived in special wards in the Tokyo Metropolis (OR = 4.2, CI[2.2, 8.3], p < .001), had child abuse concerns (OR = 2.1, CI [1.5, 2.9], p < .001), and had no time to relax with their child (OR = 4.5, CI [3.1–6.7], p < .001) exhibited higher odds ratios for child-rearing isolation, compared to mothers who did not exhibit these characteristics.

Conclusions
Findings showed the impact of urban living on maternal health and the influence of isolation on mothers’ anxiety about child-rearing and their potential for child maltreatment. The importance of fathers’ involvement in child-rearing in preventing maternal child-rearing isolation was highlighted.

, is considered. The partition function is computed using the Izergin–Korepin method, generalizing the result of Foda and Zarembo from the rational to the trigonometric case. Thereafter, we specify the parameters in Kuperberg’s way to get a formula for the number of states as a determinant of Wilson polynomials. We relate this to a new type of alternating sign matrices, similar to how the six-vertex model with domain wall boundary conditions is related to normal alternating sign matrices. In an appendix, we compute the partition function again, showing that it is also possible to find it with the method of Foda and Wheeler.
Constructing theoretically informed measures of pause duration in experimentally manipulated writing
Authors: Hall Sophie , Baaijen Veerle M. , Galbraith David 
Published: April 2022

AbstractThis paper argues that traditional threshold-based approaches to the analysis of pauses in writing fail to capture the complexity of the cognitive processes involved in text production. It proposes that, to capture these processes, pause analysis should focus on the transition times between linearly produced units of text. Following a review of some of the problematic features of traditional pause analysis, the paper is divided into two sections. These are designed to demonstrate: (i) how to isolate relevant transitions within a text and calculate their durations; and (ii) the use of mixture modelling to identify structure within the distributions of pauses at different locations. The paper uses a set of keystroke logs collected from 32 university students writing argumentative texts about current affairs topics to demonstrate these methods. In the first section, it defines how pauses are calculated using a reproducible framework, explains the distinction between linear and non-linear text transitions, and explains how relevant sections of text are identified. It provides Excel scripts for automatically identifying relevant pauses and calculating their duration. The second section applies mixture modelling to linear transitions at sentence, sub sentence, between-word and within-word boundaries for each participant. It concludes that these transitions cannot be characterised by a single distribution of “cognitive” pauses. It proposes, further, that transitions between words should be characterised by a three-component distribution reflecting lexical, supra-lexical and reflective processes, while transitions at other text locations can be modelled by two-component distributions distinguishing between fluent and less fluent or more reflective processing. The paper concludes by recommending that, rather than imposing fixed thresholds to distinguish processes, researchers should instead impose a common set of theoretically informed distributions on the data and estimate how the parameters of these distributions vary for different individuals and under different conditions.
