Associations between adversity and youth psychopathology likely vary based on the types and timing of experiences. Major theories suggest that the impact of childhood adversity may either be cumulative in type (the more types of adversity, the worse outcomes) or in timing (the longer exposure, the worse outcomes) or, alternatively, specific concerning the type (e.g., parenting, home, neighborhood) or the timing of adversity (e.g., specific developmental periods). In a longitudinal sample from the Future of Families and Wellbeing Study (N = 4,210), we evaluated these competing hypotheses using a data-driven structured life-course modeling approach using risk factors examined at child age 1 (infancy), 3 (toddlerhood), 5 (early childhood), and 9 (middle childhood). Results showed that exposures to more types of adversity for longer durations (i.e., cumulative in both type and timing) best predicted youth psychopathology. Adversities that occurred at age 9 were better predictors of youth psychopathology as compared to those experienced earlier, except for neglect, which was predictive of internalizing symptoms when experienced at age 3. Throughout childhood (across ages 1–9), aside from the accumulation of all adversities, parental stress and low collective efficacy were the strongest predictors of internalizing symptoms, whereas psychological aggression was predictive of externalizing symptoms.

Autoimmune encephalitis is increasingly recognized as a neurologic cause of acute mental status changes with similar prevalence to infectious encephalitis. Despite rising awareness, approaches to diagnosis remain inconsistent and evidence for optimal treatment is limited. The following Canadian guidelines represent a consensus and evidence (where available) based approach to both the diagnosis and treatment of adult patients with autoimmune encephalitis. The guidelines were developed using a modified RAND process and included input from specialists in autoimmune neurology, neuropsychiatry and infectious diseases. These guidelines are targeted at front line clinicians and were created to provide a pragmatic and practical approach to managing such patients in the acute setting.

The country has been gripped by the events that have unfolded in the wake of the police killings of George Floyd and Breonna Taylor. In response to these new examples of long-standing police violence, there have been calls to substantially reimage policing to reduce the number of violent incidents that occur between officers and the public and to combat officers’ disproportionate use of force with Black Americans. In this article, we call on industrial-organizational (I-O) psychologists to leverage their expertise to help actuate meaningful change within law enforcement. To help guide our collective efforts as a field, we provide a review of the current state of affairs as they relate to recruitment, selection, training, performance management, occupational stress, and organizational culture in law enforcement and then offer recommendations for ways to change current practices to encourage more equitable and responsible policing. We also highlight areas in which further investigation is needed and urge I-O psychologists to invest in building the knowledge necessary to inform future practices. We hope this article can facilitate a discussion about how our field can contribute to achieving evidence-based and lasting change that benefits officers and the members of the communities they serve.

The church of St Michael and All Angels, Averham, is largely constructed of counter-pitched rubble and has long been interpreted as being of the early Norman period. Recent archaeological investigations by the authors have revealed conclusive evidence that the date of part of the fabric is pre-Conquest and that the west tower was originally a possible two-storey porch. Ground-based remote sensing has further revealed complex anomalies in the south and east walls of the tower.

Herbivore distribution throughout Africa is strongly linked to mean annual precipitation. We use that relationship to predict functional group composition of herbivore communities during the last glacial maximum (ca. 21 ka) on the now submerged Palaeo-Agulhas Plain (PAP), South Africa. We used metabolic large herbivore biomass (MLHB) from 39 South African protected areas, in five functional groups (characterized by behavior and physiology). We examined how modern factors influenced MLHB and considered the effects of biome, annual rainfall, percentage winter rainfall, and protected area size. Overall, biome was the most important factor influencing the relationship between MLHB and rainfall. In general, MLHB increased with rainfall, but not for the grassland biome. Outside grasslands, most functional groups’ metabolic biomass increased with increasing rainfall, irrespective of biome, except for medium-sized social mixed feeder species in savanna and thicket. Protected area size was influential for medium-sized social mixed feeders and large browsers and rainfall influenced medium-sized social mixed feeders, offering some perspectives on spatial constraints on past large herbivore biomass densities. These results improve our understanding of the likely herbivore community composition and relative biomass structure on the PAP, an essential driver of how early humans utilized large mammals as a food resource.

Childhood adversity is thought to undermine youth socioemotional development via altered neural function within regions that support emotion processing. These effects are hypothesized to be developmentally specific, with adversity in early childhood sculpting subcortical structures (e.g., amygdala) and adversity during adolescence impacting later-developing structures (e.g., prefrontal cortex; PFC). However, little work has tested these theories directly in humans. Using prospectively collected longitudinal data from the Fragile Families and Child Wellbeing Study (FFCWS) (N = 4,144) and neuroimaging data from a subsample of families recruited in adolescence (N = 162), the current study investigated the trajectory of harsh parenting across childhood (i.e., ages 3 to 9) and how initial levels versus changes in harsh parenting across childhood were associated with corticolimbic activation and connectivity during socioemotional processing. Harsh parenting in early childhood (indexed by the intercept term from a linear growth curve model) was associated with less amygdala, but not PFC, reactivity to angry facial expressions. In contrast, change in harsh parenting across childhood (indexed by the slope term) was associated with less PFC, but not amygdala, activation to angry faces. Increases in, but not initial levels of, harsh parenting were also associated with stronger positive amygdala–PFC connectivity during angry face processing.

Psychosocial stress in childhood and adolescence is linked to stress system dysregulation, although few studies have examined the relative impacts of parental harshness and parental disengagement. This study prospectively tested whether parental harshness and disengagement show differential associations with overall cortisol output in adolescence. Associations between overall cortisol output and adolescent mental health problems were tested concurrently. Adolescents from the Fragile Families and Child Wellbeing Study (FFCWS) provided hair samples for cortisol assay at 15 years (N = 171). Caregivers reported on parental harshness and disengagement experiences at 1, 3, 5, 9, and 15 years, and adolescents reported at 15 years. Both parent and adolescent reported depressive and anxiety symptoms and antisocial behaviors at 15. Greater parental harshness from 1–15 years, and harshness reported at 15 years in particular, was associated with higher overall cortisol output at 15. Greater parental disengagement from 1–15 years, and disengagement at 1 year specifically, was associated with lower cortisol output. There were no significant associations between cortisol output and depressive symptoms, anxiety symptoms, or antisocial behaviors. These results suggest that the unique variances of parental harshness and disengagement may have opposing associations with cortisol output at 15 years, with unclear implications for adolescent mental health.

This paper uses evidence from a previously unresearched ecclesiastical textile associated with Archbishop John Morton (c 1420−1500) to generate new insights into the material culture of the Roman Catholic faith before, during and after the penal period in England (c 1558−1829). This composite textile was initially thought to be made up of fragments of a late 1400s cope bearing Morton’s rebus, reconfigured as an altar frontal, which had survived in the house of an important Roman Catholic family. The embroidered motifs include a unique Lily Crucifix. The textile’s complex biography is ‘unpicked’ using physical and textual evidence to understand its changing forms, roles and significance. Analysis of the material and construction, combined with evidence gained through X-radiography, showed the frontal to be composed of parts of a cope and at least one other vestment, with a now missing image of the Annunciation. Mapping the stages of fragmentation, removal and re-modelling demonstrates the transformation of significant mainstream vestments into other forms. The paper illuminates aspects of Morton’s faith and provides new insights into the practices of recusant Roman Catholics.

Although the argument of the Essay on population originated in a family disagreement between Malthus and his father Daniel, who idolized Rousseau, and the Essay itself attacks Condorcet and Godwin, both of whom drew on Rousseau's ideas about human perfectibility, Malthus's project can plausibly be seen as an extension of the social theory set out above all in Rousseau's Discourse on the origin of inequality. Malthus was animated by some of Rousseau's characteristic concerns, and he deployed recognizable versions of some of Rousseau's distinctive arguments, in particular relating to the natural sociability and natural condition of humankind, conjectural history, and political economy, especially with respect to the question of balanced growth. His arguments about ‘decent pride’, furthermore, that were emphasized in later editions of the Essay map neatly onto what has been called ‘uninflamed amour-propre’ in the Rousseau literature. When we treat the social question as a nineteenth-century question, or when we locate its origins in the post-Revolutionary political controversies of the 1790s, we risk losing sight of the way in which what was being discussed were variations on mid-eighteenth-century themes.

Background: The antiquated standard reference range of 0.15–0.45 g/L for cerebrospinal fluid total protein (CSF-TP) is well entrenched in medical literature and laboratory operating procedures across the world. Methods: We conducted a web-based survey with a response rate of 34.9% through the listserv of the Canadian Neurological Sciences Federation. Additional laboratory reference data were collated by telephone interview of hospital laboratory technologists across Canada. Results: A total of 142 site responses were obtained: 64.1% from academic/tertiary hospitals and 35.9% from community hospitals. A strong majority (80.4%) of both types of institutions reported using a CSF-TP upper reference limit of 0.45 g/L or less. As a rule, no age adjustments were implemented in CSF-TP-level interpretation. Conclusions: Recent well-powered laboratory reference studies have documented CSF-TP upper reference limits that are above 0.6 g/L starting at age 50, with incremental limits partitioned by subsequent decades of age. The conventional 0.45 g/L limit could lead to false positive results. Our survey suggests there is a need to consider a wide adoption of data-driven, rather than historical, reference values.
