Maternal depressive symptoms are a crucial risk factor for children’s internalizing problems, though positive mother–child relationships may buffer this risk transmission. Mother–child physiological coregulation (e.g., synchrony) has emerged as a potentially important mechanism of developmental psychopathology and may play a role in the transmission of internalizing symptoms. In this two-wave longitudinal study, we examined whether and how mother–infant physiological synchrony (of respiratory sinus arrhythmia; RSA) moderated the association between maternal postnatal depressive symptoms and children’s internalizing problems in a rural, low-SES community sample (N = 166 dyads). At 6 months, mother–infant RSA synchrony and infant negative affect were assessed during free play. Mother reported their depressive symptoms at 6 months and children’s internalizing problems at 24 months. Multilevel structural equation models indicated that mother–infant dyads demonstrated significant and positive RSA synchrony on average and RSA synchrony significantly moderated the association between maternal depressive symptoms and children’s internalizing problems even after controlling for infant negative affect. Greater maternal depressive symptoms were associated with higher child internalizing problems when RSA synchrony was lower but not when it was higher. This finding suggests that mother–infant RSA synchrony may operate as a resilience factor for the intergenerational transmission of internalizing symptoms in community samples.

Applying a coastal-geoarchaeological approach, we synthesize stratigraphic, sedimentological, mollusk-zooarchaeological, and radiometric datasets from recent excavations and sediment coring at Harbor Key (8MA15)—a shell-terraformed Native mound complex within Tampa Bay, on the central peninsular Gulf Coast of Florida. We significantly revise the chronological understanding of the site and place it among the relatively few early civic-ceremonial centers in the region. Analyses of submound contexts revealed that the early first millennium mound center was constructed atop a platform of sand and ex situ cultural shell deposits that were reworked during ancient storm landfalls around 2000 BP. We situate Harbor Key within a seascape-scale stratigraphic and paleoenvironmental framework and show that the shellworks comprise an artificial barrier protecting the leeward estuary basin (and productive inshore wetlands) from high-energy conditions of the open bay and swells from the Gulf of Mexico. The sedimentary and archaeological records attest to the long-term history of morphodynamic interaction between coastal processes and Indigenous shell terraforming in the region and suggest that early first millennium mound building in Tampa Bay was tied to the recognition and reuse of antecedent shellworks and the persistent management of encompassing cultural seascapes.

The reproduction of bopyrid isopod parasites is thought to occur immediately following host ecdysis, but direct observations supporting this hypothesis are limited. The aim of this study was to describe the reproductive behaviour of the bopyrid isopod Bopyrus crangorum relative to host ecdysis based on video recordings. Several hours after host ecdysis, biphasic moulting of female parasites was observed. The cuticle of the posterior body was shed before that of the anterior body at an interval of 1 h. Two hours after female moulting, the male repeatedly moved from its initial position between the female pleopods and stopped at the anterior end of the fifth oostegite, immediately above the gonopore. To our knowledge, this repeated visiting behaviour by males has not been previously observed in bopyrid isopods. Oviposition through the female gonopore occurred 33 min later. The male-removal experiment showed that females with their males removed after visits to the gonopore oviposited eggs, whereas females with their males removed before visits did not. We propose that repeated visits by males to the gonopore are attempts to inseminate the female. We hypothesised that sperm are released onto the external surface of each gonopore and that the eggs are fertilised as they pass through the opening, which would explain the synchronous development of fertilised eggs inside the marsupium. The present study provides new information on the life history of bopyrid isopods, which allows for a better understanding of the host–parasite relationship.

Excessive reassurance seeking (ERS) is believed to play an important role in maintaining mental health problems, in particular anxiety disorders such as obsessive-compulsive disorder and health anxiety. Despite this, therapists commonly give into patients’ requests for reassurance in clinical settings and are generally unsure how to handle the issue both in therapy itself and concerning advice to the patient’s loved ones. In order to increase our understanding of therapists’ perception of ERS and how interventions for ERS are managed, we examined therapists’ perception and understanding of ERS, including its function, which emotional problems therapists associate it with, and what treatment interventions they consider important for managing ERS. Qualified therapists (n=197) were benchmarked against international expert consensus (n=20) drawn from leading clinical researchers. There was evidence that clinical experience right up to the expert level may result in less reassurance giving within treatment settings. Still, there were enough inconsistencies between the experts and other clinicians to suggest that ERS remains poorly understood and is not consistently dealt with clinically. Results are discussed in terms of how current treatment interventions may be limited for treating ERS, highlighting the need to consider new approaches for dealing with this complicated interpersonal behaviour.

George Finlay was a British gentlemen and philhellene, resident in Greece in the mid-nineteenth century. His journals, letters, library and antiquities now reside at the British School at Athens, collections that provide a wealth of information both about Finlay himself and about the world of his contemporaries. This paper looks at two episodes from Finlay’s life as preserved in his archive, documenting two overseas travels: the first is a tour around Egypt, Jerusalem and the Near East in 1845 and 1846, and the second is a series of repeat visits to Switzerland beginning in 1859 and continuing in the late 1860s. By looking at Finlay’s itineraries and at the activities he undertook in Egypt and Switzerland, and by analysing what and how Finlay chose to document in his notebooks, the aim of this paper is to understand more about Finlay’s motivations for travel and his intellectual formation. While Finlay’s time in the Near East was likely spurred by the recent publication of handbooks and by a developing fashion for (biblical) tourism, his time in Switzerland coincided with the flurry of excitement from recent excavations of the Swiss lake villages, allowing Finlay to re-engage an interest in prehistory that he had long since developed. In each case, Finlay’s social connections and his networks played a large part in directing his programme.

Can nativist attitudes condition support for LGBT+ rights? The sustained advance in pro-LGBT+ attitudes in the West often contrasts with the greening of anti-immigrant sentiment propagated by nativist supply-side actors. We argue that these parallel trends are causally connected, theorizing that exposure to sexually conservative ethnic out-groups can provoke an instrumental increase in LGBT+ inclusion, particularly among those hostile toward immigration. Leveraging experiments in Britain and Spain, we provide causal evidence that citizens strategically liberalize their levels of support for LGBT+ rights when opponents of these measures are from the ethnic out-group. In a context where sexuality-based liberalism is nationalized, increasing tolerance toward LGBT+ citizens is driven by a desire among nativist citizens to socially disidentify from those out-groups perceived as inimical to these nationalized norms. Our analyses provide a critical interpretation of positive trends in LGBT+ tolerance with instrumental liberalism masking lower rates of genuine shifts in LGBT+ inclusion.

The spread of the brown seaweed Sargassum muticum is one of the best documented invasions of a non-native marine species. Observation of a potentially established population of S. muticum in the Orkney Islands archipelago, located off the northern coast of Scotland, was reported by recreational snorkellers in 2019 and 2020. The present study summarises a focussed investigation to confirm its presence and current local distribution, using data from 46 survey sites monitored as a part of the Orkney Islands Council Harbour Authority monitoring programme. Findings in this study represent the most northerly record of an established population of S. muticum in the United Kingdom, extending the latitudinal range in this country by 1.44° (159 km) northwards, and indicate only localised presence of this species. Analysis of a partial cytochrome oxidase I gene sequence confirmed the visual species identification. Possible vectors of introduction, gaps in the geographic range, local ecological and economic impacts, and the potential ameliorating factor of deep rockpools on wave exposed shores for S. muticum are discussed.

To cultivate zooplankton species with highly fragile mucoid structures, a new type of cultivation device was developed, which uses a novel method to gently circulate the water in the culture vessel. Using this device, a species of the fritillarid appendicularia (Fritillaria sp.) collected in Sagami Bay was successfully cultivated. This form resembles Fritillaria haplostoma or Fritillaria formica tuberculata, but some taxonomical characteristics differed from those of the latter forms. A novel device comprising a polycarbonate bucket with a motor-driven rotating cylinder inserted into the water in the bucket was developed and maintained Fritillaria sp. over ten filial generations in the laboratory. The animals reached trunk lengths of 1026 ± 85 μm (mean ± SD) four days after fertilization at 23°C. The instantaneous growth rates were calculated as 1.11–1.72 at 20–26°C, representing a 3.0–5.6-fold daily increase in body weight. The house constructed by this species is extraordinarily fragile, typically has a barrel-like or cylindrical shape, and accommodates its entire body and food-concentrating filter. At 23°C, the species produced houses at a rate of 28 ± 2.8 houses d−1. The new device is useful for the continuous cultivation of the fragile form of fritillarid appendicularia, and even for various other zooplankton. It also shows that Fritillaria sp. could be a significant secondary producer and transporter of organic matter in marine ecosystems due to its high growth and house production rates.

One of the things Rosen's very interesting and wide-ranging book shows is why history and the goal of moral advance in history have become so important. We want to believe in moral advance (I am shunning the word “progress” with its resonance of steady uninterrupted forward movement), but we feel incapable of affirming this. What the Lisbon earthquake did to the eighteenth-century versions of Providence, Auschwitz has done for us. Rosen cites Adorno to good effect.

Infection prevention program leaders report frequent use of criteria to distinguish recently recovered coronavirus disease 2019 (COVID-19) cases from actively infectious cases when incidentally positive asymptomatic patients were identified on routine severe acute respiratory coronavirus virus 2 (SARS-CoV-2) polymerase chain reaction (PCR) testing. Guidance on appropriate interpretation of high-sensitivity molecular tests can prevent harm from unnecessary precautions that delay admission and impede medical care.
