Black and Latinx caregivers face high risk for parenting stress and racism-related stress due to experiences of racial discrimination (RD). This study aimed to explore the associations between RD, parenting stress, and psychological distress in caregiver-child dyads, as well as the impact of a mentalizing-focused group intervention on caregivers’ experiences of RD distress. Ethnoracially minoritized caregivers of children aged 5–17 years old participated in a non-randomized clinical trial (N = 70). They received either a 12-session mentalizing-focused group parenting intervention or treatment-as-usual in outpatient psychiatry. We assessed self-reported frequency and distress related to RD, parenting stress, and psychological distress at baseline (T1) and post-intervention (T2). Caregiver- and self-reported child psychological distress were also measured. The results showed that greater RD frequency and greater RD distress separately predicted higher overall parenting stress and parental role-related distress. Greater RD distress was linked to increased psychological distress in caregivers. Similarly, greater RD frequency and distress among caregivers were associated with higher caregiver-reported, but not self-reported, child psychological distress. No significant changes in RD distress were observed between T1 and T2 for either of the treatment groups. These findings highlight the exacerbating role of RD on parenting stress and psychological distress among ethnoracially minoritized caregivers and their children.

Kelp forests are being degraded and/or lost in many regions, and as such, interest in active kelp restoration approaches to reinstate forests is growing. ‘Green gravel’ is a promising new kelp restoration technique that involves seeding small rocks with kelp zoospores, rearing the gametophyte and juvenile sporophyte stages in aquaria before outplanting them at restoration sites. However, to be considered a viable approach to kelp forest restoration, the efficacy of this technique needs to be assessed across a range of environmental contexts and kelp species. Here, we aimed to understand the utility of green gravel as a kelp restoration technique for wave-exposed intertidal shores. Two substrate types – gravel and cobbles – were seeded with Saccharina latissima, reared in the aquarium and outplanted at two sites along the northeast coast of England. Outplanted rocks were monitored for retention, and the density and length of S. latissima. Juvenile sporophytes persisted on both rock types, although declines in density and variations in length were observed over time. Substrate retention was low, with gravel more likely to be removed from restoration sites compared to cobbles, and all outplanted rocks were lost after eight months. While our initial testing of the green gravel restoration technique on wave-exposed shores was not successful, our results provide important insights for developing/refining the technique and a baseline for comparison for future efforts. However, prior to commencing large-scale kelp restoration in wave-exposed areas using green gravel, further testing of the technique and comparisons with other restoration approaches are needed.

As an environmental factor, temperature impacts the distribution of species and influences interspecific competition. The molecular chaperones encoded by small heat shock proteins (sHsps) are essential for rapid, appropriate responses to environmental stress. This study focuses on Hsp20.8, which encodes a temperature-responsive sHsp in Liriomyza trifolii, an insect pest that infests both agricultural and ornamental crops. Hsp20.8 expression was highest at 39℃ in L. trifolii pupae and adults, and expression levels were greater in pupae than in adults. Recombinant Hsp20.8 was expressed in Escherichia coli and conferred a higher survival rate than the empty vector to bacterial cells exposed to heat stress. RNA interference experiments were conducted using L. trifolii adults and prepupae and the knockdown of Hsp20.8 expression increased mortality in L. trifolii during heat stress. The results expand our understanding of sHsp function in Liriomyza spp. and the ongoing adaptation of this pest to climate change. In addition, this study is also important for predicting the distribution of invasive species and proposing new prevention and control strategies based on temperature adaptation.

The article seeks to fill a gap in existing scholarship on explicit and implicit linguistic, ethnic, and national classifications in Habsburg schools and their effects. It attempts to reconstruct the classifications that appeared in textbooks and other teaching materials as well as in daily practice, pupils’ exposure to them, and their engagement with these categories. Temporally, the study begins with the establishment of compulsory education (1774) and ends in the revolutionary period of 1848–49 and focuses on the Slavophone population of the Habsburg crownlands Carniola, Carinthia, Styria, and the Austrian Littoral. Our research suggests that systematic and uniform classification schemes were not yet in place in the school environment in the period under review. As a result, the influence of classificatory systems on identifications was limited. If anything, the schools inadvertently reproduced existing local and provincial identifications while the students’ limited internalization of emerging transregional identifications only happened through their personal relationships with a few teachers and peers. The transition from familiarization with emerging transregional ethnolinguistic identifications through personal networks to the systemic (and often completely unintentional) reproduction of nationalist ideology happened only after 1848.

We prove that the multiplicity of a filtration of a local ring satisfies various convexity properties. In particular, we show the multiplicity is convex along geodesics. As a consequence, we prove that the volume of a valuation is log convex on simplices of quasi-monomial valuations and give a new proof of a theorem of Xu and Zhuang on the uniqueness of normalized volume minimizers. In another direction, we generalize a theorem of Rees on multiplicities of ideals to filtrations and characterize when the Minkowski inequality for filtrations is an equality under mild assumptions.

On 25 October 2021, Nigeria became the second country in the world, and the first in Africa, to launch a central bank digital currency. Launched with the tag line “Same Naira. More possibilities”, the Central Bank of Nigeria publicized the eNaira as having the capability to deepen financial inclusion, reduce the cost of financial transactions and support a more efficient payment system. However, more than one year after its launch, its usage is yet to gain a critical mass. This article identifies the significant challenges that make the eNaira unacceptable and potentially ineffective. First, its status as legal tender is questionable; secondly, it undermines privacy, a critical component of physical cash. Thirdly, it is incapable of wide acceptance by individuals and entities across Nigeria. The article explains each of these challenges and proposes a roadmap to the eNaira's acceptance and effectiveness.

To survive over time, a diaspora must create sites of belonging and micro places in which to concentrate the main elements of its “iconography” that can consolidate social networks. This article analyzes how second-generation Greeks in Italy fit into diaspora networks by investigating the ways in which they define their sense of Greekness and use their ethnic resources. The findings of field research show a weakness of (formal and informal) social network ties and the pre-eminence of the family’s role in the process of sociocultural identification and ethnic identity construction. In fact, the second generation’s “ways of belonging” and the sense of attachment to Greece have an autonomous significance and are expressed more at a familial level and less collectively. Familial socialization plays a mediating role in the process of identification and transmission of Greekness, as well as in guiding ways of employing ethnic resources, contributing to the maintenance of the diaspora.

Chaque année, les Instituts de recherche en santé du Canada (IRSC) subventionnent le Programme d’été sur le vieillissement (PEV). Cette année, la semaine de formation qui rassemblait des étudiants canadiens de tous les cycles supérieurs avait pour thème la recherche multidisciplinaire au quatrième âge. Cette note de recherche présente trois éléments de réflexion de deux participants de l’édition 2023 du PEV : 1) les enjeux liés au vieillissement sont des occasions de transformer les paradigmes de la recherche; 2) la recherche collaborative doit être sociétale, et s’étendre au-delà du cercle restreint des milieux universitaires; 3) les critères d’équité, de diversité et d’inclusion intégrés aux projets de recherche doivent se refléter au sein des organisations qui mènent la recherche.

Biophysical conditions played a fundamental role in early human colonization of insular territories, particularly in food-producing societies dealing with limited resources and the challenges of maintaining a sustainable carrying capacity. Studies on past human colonization of small oceanic islands thus offer insights into economic plasticity, ecological impacts, and adaptation of early food-producing groups. On the coast of southern Chile, early evidence is dated to 950 cal BP of island colonization by coastal populations with mainland subsistence systems based on the exploitation of marine resources, along with gathering, managing, and cultivating plants and hunting terrestrial animals. Strikingly, the extent to which these mixed economies contributed to insular colonization efforts is largely unknown. Here we used organic residue analysis of ceramic artifacts to shed light on the subsistence of populations on Mocha Island in southern Chile. We extracted and analyzed lipids from 51 pottery sherds associated with the El Vergel cultural complex that flourished in southern Chile between 950 and 400 cal BP. Chemical and stable isotope analysis of the extracts identified a range of food products, including C3 and C4 plants and marine organisms. The results reveal the central role of mixed subsistence systems in fueling the colonization of Mocha Island.
