Published: March 2024

Abstract
We explored participants’ experiences of a counsellor-supported PTSD Coach mobile application intervention (PTSD Coach-CS) in a randomised controlled trial. PTSD Coach-CS participants, who received the intervention and self-completed a custom-designed questionnaire at intervention completion were included (n = 25; female = 20; ages 19–59; isiXhosa = 22). This questionnaire comprised questions regarding the feasibility, acceptability and potential impact of the PTSD Coach-CS intervention, and general psychological support in our setting. Data were analysed using Braun and Clarke’s thematic analysis. Three main themes emerged. (i) Participants’ largely positive experiences of treatment procedures included the safe space created by the counsellor support in combination with the PTSD Coach application, allowing them to learn about and understand their lived experiences, and to accept their PTSD diagnoses. (ii) Positive perceptions of the PTSD Coach application, yet raising important concerns (e.g., lack of family involvement) for future consideration. (iii) Intervention-specific and systemic treatment barriers (e.g., stigma) providing important information to inform and increase the usefulness of the PTSD Coach-CS intervention. The findings suggest that the PTSD Coach-CS intervention may help address the need for access to suitable care for South African adults with PTSD. Some contextual barriers must be considered in further intervention implementation.
Hegel, Colonialism and Postcolonial Hegelianism
Authors: Mascat Jamila M. H. 
Published: March 2024

AbstractThis article aims to shed light on Hegel's conception of colonialism and its implications for the postcolonial reception of Hegel. Drawing on the abundant literature on the topic, it begins by engaging with Hegel's understanding of colonialism through a close reading of relevant passages of his works, in particular the Heidelberg Vorlesungen über Naturrecht und Staatswissenschaft (1817–18), the Grundlinien der Philosophie des Rechts (1821), the Vorlesungen über die Philosophie des Rechts (1819/20, 1821/22, 1822/23, 1824/25) and the Vorlesungen über die Philosophie der Weltgeschichte (1822/23, 1830). Having mapped and reconstructed Hegel's conception of colonialism through his writings and lectures, the article argues that his account of Europe's modern colonial expansion is based primarily on economic considerations, rather than on civilizational assumptions proclaiming the spiritual superiority of European peoples—to which Hegel nevertheless subscribes. The conclusion explores distinct and divergent postcolonial perspectives for engaging with the contemporary legacy of Hegelianism. It addresses, on the one hand, Tibebu's critical reading of Hegel's philosophical enterprise as ‘the coldest rationalisation of genocidal murder and carnage’ based on ‘paradigmatic apartheid’ and, on the other, Brennan's redemptive reading of Hegel, which values his theoretical contribution to the shaping of 20th century anticolonial thought. After contrasting these two interpretations, the article argues in favour of postcolonial strategies for critical reappropriation and sabotage of the legacy of Hegel's philosophy.
Examples of hyperbolic spaces without the properties of quasi-ball or bounded eccentricity
Authors: You Qizheng , Zhang Jiawen 
Published: March 2024

AbstractIn this note, we present examples of non-quasi-geodesic metric spaces which are hyperbolic (i.e., satisfying Gromov’s
$4$
-point condition) while the intersection of any two metric balls therein does not either ‘look like’ a ball or has uniformly bounded eccentricity. This answers an open question posed by Chatterji and Niblo.

AbstractThis essay introduces a review dossier dedicated to Daniel Laqua's Activism across Borders since 1870: Causes, Campaigns and Conflicts in and beyond Europe (London, 2023). The dossier features comments by four historians – Constance Bantman, Georgina Brewis, Nicole Robertson, and Mark Hurst – as well as a response from Laqua himself. Laqua's book provides a framework for studying different forms of transnational activism in connection to one another.
Reflections on Activism across Borders: A Response
Authors: Laqua Daniel 
Published: March 2024

AbstractThis essay discusses different approaches to studying transnational activism in historical perspective. In doing so, it concludes a review dossier in which several historians have commented on aspects of Daniel Laqua's book Activism across Borders since 1870: Causes, Campaigns and Conflicts in and beyond Europe (London, 2023). The author responds to the preceding pieces by addressing the contributors’ questions and arguments, while also noting how their pieces have applied his book's framework to different causes (e.g. anarchism, feminism, human rights, humanitarianism, labour). Moreover, this essay raises several wider points regarding the subject under consideration. For example, it stresses that activists’ notions regarding the interconnectedness of different causes could generate fresh ruptures. The discussion highlights the amorphous nature of transnational activism, including its potential use by vastly different movements, and it situates the book within a broader, and developing, research agenda.
A new species of Hourstonius (Amphipoda: Amphilochidae) from Todos-os-Santos Bay, Bahia State, Brazil, with an overview of the genus across the globe
Authors: Alves Jessika , Neves Elizabeth G. , Johnsson Rodrigo 
Published: March 2024

Abstract
Amphilochidae comprises 92 species of small and colourful amphipods that live associated with sessile marine organisms. Hourstonius is one of the most diverse genera with 17 described species, most of the species are recorded from North Temperate Pacific and Tropical Atlantic and live in shallow waters. Only three species of Amphilochidae are recorded in Brazil, and from the genus Hourstonius, there is a single species, H. wakabarae. In the present work, we describe a new species of Hourstonius from Todos-os-Santos Bay, the second species of the genus to the country and the first record of this genus from Bahia State. A taxonomic key and an overview of the genus across the globe are also provided.
Rediscovery of the Neotropical orchid Porroglossum parsonsii and recommendations for its conservation

Published: March 2024

AbstractUnderstanding the distribution and habitat requirements of species is crucial for designing conservation actions, yet this information is not available for many plant species. We report the first confirmed wild populations of Porroglossum parsonsii, which, because of its horticultural value, is commercialized in national and international markets, from where it was first described to science. Our large-scale survey of 341 10 × 30 m plots spanning Andean forests, paramo habitats and pasturelands in Colombia suggests that P. parsonsii has a restricted geographical distribution in Andean forests with high forest cover (71.4–86.2%), where it occurs in low numbers (5–17 individuals per plot). Because of its market value (USD 18–20 per plant) there is a risk the species could be collected illegally, and therefore the habitat of the species in the Santuario de Fauna y Flora de Iguaque requires appropriate conservation.
Coinfection of slime feather duster worms (Annelida, Myxicola) by different gregarine apicomplexans (Selenidium) and astome ciliates reflects spatial niche partitioning and host specificity
Authors: Park Eunji , Leander Brian 
Published: March 2024

AbstractIndividual organisms can host multiple species of parasites (or symbionts), and one species of parasite can infect different host species, creating complex interactions among multiple hosts and parasites. When multiple parasite species coexist in a host, they may compete or use strategies, such as spatial niche partitioning, to reduce competition. Here, we present a host–symbiont system with two species of Selenidium (Apicomplexa, Gregarinida) and one species of astome ciliate co-infecting two different species of slime feather duster worms (Annelida, Sabellidae, Myxicola) living in neighbouring habitats. We examined the morphology of the endosymbionts with light and scanning electron microscopy (SEM) and inferred their phylogenetic interrelationships using small subunit (SSU) rDNA sequences. In the host ‘Myxicola sp. Quadra’, we found two distinct species of Selenidium; S. cf. mesnili exclusively inhabited the foregut, and S. elongatum n. sp. inhabited the mid to hindgut, reflecting spatial niche partitioning. Selenidium elongatum n. sp. was also present in the host M. aesthetica, which harboured the astome ciliate Pennarella elegantia n. gen. et sp. Selenidium cf. mesnili and P. elegantia n. gen. et sp. were absent in the other host species, indicating host specificity. This system offers an intriguing opportunity to explore diverse aspects of host–endosymbiont interactions and competition among endosymbionts.
Fear, trust, and compliance with COVID-19 measures: a study of the mediating effect of trust in government on the relationship between fear and compliance
Authors: Hrbková Lenka , Kudrnáč Aleš 
Published: March 2024

AbstractAs the COVID-19 pandemic became an unprecedented global threat, it was accompanied by an increase in trust in governments as well as fear among the public. Previous research suggests that both institutional trust and fear contribute to the willingness of citizens to comply with anti-pandemic measures. Moreover, fear during the contagion also increases trust in government. This article presents a test of the mediation of the effects of fear on compliance through trust. In addition, it differentiates between three different facets of COVID-19-related fear: fear of the disease, fear of economic consequences, and fear of political consequences. The results suggest that while fear of the disease increases compliance, fear of political consequences decreases compliance. Moreover, the effects of fear are mediated through trust in government. The negative impact of fear of political consequences on compliance increased between April and December 2020.
Impact of talker variability on language development in two-year-olds
Authors: Zhao Jing , Kobayashi Tessei , Haryu Etsuko 
Published: March 2024

AbstractThis research investigated the impact of the number of talkers with whom children engage in daily conversation on their language development. Two surveys were conducted in 2020, targeting two-year-olds growing up in Japanese monolingual families. Caregivers reported the number of talkers in three age groups and children’s productive vocabulary via questionnaires. The results demonstrated significant effects of variability in talkers in fifth grade or above in Study 1 (N = 50; male = 23; r = .372) and in adult talkers in Study 2 (N = 175; non-nursery going; male = 76; r = .184) on children’s vocabulary development, after controlling for language exposure time and demographic variables. Possible mediating factors are discussed. This research extends previous findings from immigrant bilingual children to monolingual speakers in Japan, suggesting the potential contribution of available talkers other than caregivers in conversational environments.
How Populism Affects Bioethics
Authors: Ortiz-Millán Gustavo 
Published: March 2024

Abstract
This article aims at raising awareness about the intersection of populism and bioethics. It argues that illiberal forms of populism may have negative consequences on the evolution of bioethics as a discipline and on its practical objectives. It identifies at least seven potential negative effects: (1) The rise of populist leaders fosters “epistemological populism,” devaluing the expert and scientific perspectives on which bioethics is usually based, potentially steering policies away from evidence-based foundations. (2) The impact of “moral populism” is evident in legislative prioritization of the “morality of common people,” often solicited through popular consultations on issues like abortion, drug legalization, or LGBT issues. (3) Populist distrust in autonomous governmental agencies and advisory bodies, including national bioethics commissions, can compromise expert advice, challenging both their authority and decisions. (4) Populists may erode transparency by undermining institutions responsible for it, hindering access to vital information for bioethical research. (5) “Medical populism” creates adversarial dynamics, prompting politicians to make simplistic healthcare policy decisions based on political rather than informed criteria, adversely affecting vulnerable populations. (6) Radical-right populist parties’ “welfare chauvinism” may shape healthcare policies, impacting service access and resource allocation, disproportionately affecting vulnerable groups such as migrants, but indirectly affecting the rest of the population. (7) Nationalist sentiments associated with populism may obstruct international collaborations, posing challenges for global bioethics that seeks to address ethical concerns beyond national borders. In summary, these dynamics raise significant bioethical concerns encompassing evidence-based decision-making, transparency, healthcare equity, and global collaboration. How bioethicists may respond to these challenges is discussed.
The use of private regulatory measures to create healthy food retail environments: a scoping review
Authors: Dancey Jane , Reeve Belinda , Jones Alexandra , Ferguson Megan , van Burgel Emma , Brimblecombe Julie 
Published: March 2024

Abstract

Objective:
Different forms of public and private regulation have been used to improve the healthiness of food retail environments. The aim of this scoping review was to systematically examine the types of private regulatory measures used to create healthy food retail environments, the reporting of the processes of implementation, monitoring, review and enforcement and the barriers to and enablers of these.

Design:
Scoping review using the Johanna Briggs Institute guidelines. Ovid MEDLINE, PsycINFO, Embase, CINAHL Plus, Business Source Complete and Scopus databases were searched in October 2020 and again in September 2023 using terms for ‘food retail’, ‘regulation’ and ‘nutrition’. Regulatory measure type was described by domain and mechanism. Deductive thematic analysis was used to identify reported barriers and enablers to effective regulatory governance processes using a public health law framework.

Setting:
Food retail.

Participants:
Food retail settings using private regulatory measures to create healthier food retail environments.

Results:
In total, 17 694 articles were screened and thirty-five included for review from six countries, with all articles published since 2011. Articles reporting on twenty-six unique private regulatory measures cited a mix of voluntary (n 16), mandatory (n 6) measures, both (n 2) or did not disclose (n 2). Articles frequently reported on implementation (34/35), with less reporting on the other regulatory governance processes of monitoring (15/35), review (6/35) and enforcement (2/35).

Conclusions:
We recommend more attention be paid to reporting on the monitoring, review and enforcement processes used in private regulation to promote further progress in improving the healthiness of food retail environments.
A Pre‐Monsoon Signal of False Alarms of Indian Monsoon Droughts
Authors: Goswami Bidyut Bikash 
Published: March 2024

AbstractCurrent knowledge suggests a drought Indian monsoon (perhaps a severe one) when the El Nino Southern Oscillation and Pacific Decadal Oscillation each exhibit positive phases (a joint positive phase). For the monsoons, which are exceptions in this regard, we found northeast India often gets excess pre‐monsoon rainfall. Further investigation reveals that this excess pre‐monsoon rainfall is produced by the interaction of the large‐scale circulation associated with the joint phase with the mountains in northeast India. We posit that a warmer troposphere, a consequence of excess rainfall over northeast India, drives a stronger monsoon circulation and enhances monsoon rainfall over central India. Hence, we argue that pre‐monsoon rainfall over northeast India can be used for seasonal monsoon rainfall prediction over central India. Most importantly, its predictive value is at its peak when the Pacific Ocean exhibits a joint positive phase and the threat of extreme drought monsoon looms over India.
Wildfire Smoke Directly Changes Biogenic Volatile Organic Emissions and Photosynthesis of Ponderosa Pines

Published: March 2024

AbstractWildfires are increasing across the USA. While smoke events affect human exposure and air quality, wildfire smoke effects on ecosystem‐atmosphere interactions are poorly understood. We investigate smoke effects on biogenic volatile organic compound (VOC) emissions and photosynthesis for ponderosa pines. During several wildfire smoke events, we observed photosynthetic reduction with evidence for stomatal plugging and changes in leaf‐level uptake and emission of both biogenic and wildfire VOCs. During intense smoke events, photosynthesis and VOC emissions were almost entirely suppressed, but increased dramatically upon stomatal opening. We propose four types of VOC responses to this burst in stomatal opening: post‐burst emissions, pulsed emissions, surge emissions, and post‐burst uptake. Our observations suggest that wildfire smoke can affect plant physiology and leaf‐atmosphere gas exchange.
On the Role of Indian Ocean SST in Influencing the Differences in Atmospheric Variability Between 2020–2021 and 2021–2022 La Niña Boreal Winters
Authors: Zhang Tao , Kumar Arun 
Published: March 2024

AbstractThe difference in observed atmospheric anomalies over the Northern Hemisphere winter between 2021–22 and 2020–21 La Niña years indicated a tripole pattern consisting of a Japan cyclone, a Bering Sea anticyclone, and a cyclone over the North American continent. This feature, however, was not replicated in the North American Multi‐Model Ensemble (NMME) forecasts. A set of model sensitivity experiments was performed to better understand the cause of this discrepancy. The results revealed the possible role of the influence of sea surface temperature (SST) anomalies, particularly over the Indian Ocean, on the observed circulation differences that was further modulated by internal atmospheric variability. The failure in predicting circulation changes in NMME was next attributed to the errors in SST predictions over the Indian Ocean and highlights the need for improvements in SST forecasts over this region.
Low δ18O and δ30Si TTG at ca. 2.3 Ga Hints at an Intraplate Rifting Onset of the Paleoproterozoic Supercontinent Cycle

Published: March 2024

AbstractThe start of the Paleoproterozoic supercontinent cycle is typically taken as the initiation of orogenesis at ca. 2.1 Ga leading to the assembly of Earth's first supercontinent, Columbia. However, the dearth of ca. 2.5–2.2 Ga geological records makes it difficult to deduce tectonic factors during the onset of the Paleoproterozoic supercontinent cycle. The petrogenesis of tonalite–trondhjemite–granodiorite (TTG) provides useful proxies for tracing prevailing geodynamic regimes of early continental evolution. However, marked decreases of TTG and other magmatism occurred across the Archean–Paleoproterozoic transition and have previously precluded forming testable hypotheses. Early Paleoproterozoic TTGs have been identified in the North China Craton (NCC) and other cratons, which may represent the last major pulse of TTGs globally. Here we present low δ18O and δ30Si ca. 2.3 Ga TTGs from the NCC, together with thermodynamic modeling and compilation of stable O and Si isotopes for TTGs globally through time. The ca. 2.3 Ga TTGs were derived from the partial melting of Archean basaltic crust and give lighter average zircon δ18O (3.15 ± 0.35‰) and whole‐rock δ30Si values (−0.17 ± 0.08‰) than most Archean TTGs. Considering coeval mafic‐felsic igneous rocks, and lithospheric thinning since ca. 2.5 Ga based on estimated crustal thickness through the Neoarchean–Paleoproterozoic, we posit the onset of an intraplate rifting consistent with the anomalous low‐δ18O magmatism. Continental rifting of Archean cratons/supercratons plausibly hints at the formation of rifts driving subduction initiation as the veritable onset of the Paleoproterozoic supercontinent cycle.
High‐Temperature Deformation of Enstatite‐Olivine Aggregates
Authors: Bystricky M. , Lawlis J. , Mackwell S. , Heidelbach F. 
Published: March 2024

AbstractSynthesized polycrystalline samples composed of enstatite and olivine with different volumetric ratios were deformed in compression under anhydrous conditions in a Paterson gas‐medium apparatus at 1150–1300°C, an oxygen fugacity buffered at Ni/NiO, and confining pressures of 300 or 450 MPa (protoenstatite or orthoenstatite fields). Mechanical data suggest a transition from diffusion to dislocation creep with increasing differential stress for all compositions. Microstructural analyses by optical and scanning electron microscopy reveal well‐mixed aggregates and homogeneous deformation. Crystallographic preferred orientations measured by electron backscatter diffraction are consistent with activation of the slip systems (010)[100] and (010)[001] for olivine and (100)[001] and (010)[001] for enstatite, as expected at these conditions. Nonlinear least‐squares fitting to the full data set from each experiment allowed the determination of dislocation creep flow laws for the different mixtures. The stress exponent is 3.5 for all compositions, and the apparent activation energies increase slightly as a function of enstatite volume fraction. Within the limits of experimental uncertainties, all two‐phase aggregates have strengths that lie between the uniform strain rate (Taylor) and the uniform stress (Sachs) bounds calculated using the dislocation creep flow laws for olivine and enstatite. Calculation of the Taylor and Sachs bounds at strain rate and temperature conditions expected in nature (but not extrapolating in pressure) indicates that using the dislocation creep flow law for monomineralic olivine aggregates provides a good estimate of the viscosity of olivine‐orthopyroxene rocks deforming by dislocation creep in the deeper lithosphere and asthenosphere.
