Testing the socio‐functional model: Does precarity cause conspiracy belief?
No full textAbstract: Research seeking to explain why people believe conspiracies has largely focused on intrapsychic factors, but there is growing research examining structural‐level elements of disadvantage. The socio‐functional model of conspiracy belief (Adam‐Troian et al., 2023, British Journal of Social Psychology , 62 , 136) posits that subjective feelings of permanent insecurity arising from objective material strain (i.e., precarity) cause conspiracy belief directly or indirectly through institutional distrust. Across three preregistered studies using observational longitudinal designs over 3 ( n = 637) and 11 months ( n = 832), and a between‐group experimental design ( n = 285), we use various methods to estimate causal effects for this proposition during the current cost‐of‐living crisis. In Studies 1 and 2 using random intercept cross‐lagged panel models, we find no evidence that increases in precarity temporally precede increases in conspiracy belief (or vice versa) but find stable between‐persons effects over time. In Study 3, despite successfully manipulating precarity using a self‐imagine paradigm, we find no direct or indirect effect on conspiracy belief through decreased government trust. We discuss the importance of using methods that permit credible causal inferences and key directions for future studies investigating the socio‐functional model.</p
Is anti-ligature an automatic requirement for suicide prevention?: Assessing legal obligations in alternative mental health crisis services
No full textAround the world, peer-run, bed-based services that offer voluntary support to people experiencing mental health crisis are emerging as alternatives to hospital-based mental healthcare. In Victoria, Australia, where these ‘alternative crisis services’ are expanding, a key legal question has arisen: must non-coercive settings adopt the suicide prevention architectural design (or ‘anti-ligature design’) mandated in psychiatric wards under negligence and occupational health and safety laws?This article answers that question through a three-stage study: (1) a doctrinal analysis of Victorian case law and statutes that shape duties to prevent suicide; (2) a narrative review of evidence on anti-ligature measures in hospital environments; and (3) thematic analysis of interviews with clinicians, designers, peer leaders and legal experts (n = 12).The findings indicate that empirical evidence only associates anti-ligature design with reduced suicide rates when paired with search, detention and close observation powers, which are absent from alternative crisis services. There was no evidence identified that anti-ligature design will reduce suicide in settings which do not also implement these practices.This absence of data does not justify retreat to institutional templates, especially considering key differences in the care models that differentiate alternative crisis services from traditional hospital-based offerings. Interviewees warned that conspicuous anti-ligature hardware can undermine the therapeutic value of alternative crisis services, and merely displace, rather than prevent, suicidal behaviour. Wholesale transplantation of hospital anti-ligature standards into alternative crisis services is therefore unlikely to satisfy the ‘reasonableness’ test and may contravene the therapeutic mandate of services. Instead, this study calls for regulators to endorse context-specific standards for mental health service design, some of which may require further empirical research on rights-based, peer-led safety strategies.</p
Differential modulation of rhizosphere dissimilatory nitrate reduction to ammonium (DNRA) by wheat cultivars under nitrogen deficiency
No full textNitrogen (N) deficiency constrains crop growth, which could potentially be mitigated by the plant-microbe interaction. However, the interaction between wheat and bacterial N metabolism in response to N deficiency remains poorly understood. A glasshouse experiment was conducted to investigate the rhizosphere bacterial N metabolism gene profile in the wheat rhizosphere with (+N) and without (-N) N application. Two wheat cultivars, Mace and Gladius, with contrasting reported N use efficiencies (NUE), were grown in an agriculture soil previously cropped with wheat. Metagenomic analysis, was used to examine the N metabolism gene profile of rhizobacteria under different N treatments. The result highlighted a significant difference in the rhizosphere bacterial N metabolism gene composition between Mace and Gladius. Differential abundance analysis revealed a significantly higher gene abundance involved in dissimilatory nitrate reduction to ammonium (DNRA) (nrfA, nrfD, and nrfH), in Mace under N deficiency. In contrast, no significant changes were found in Gladius. Correlation analysis highlighted a significant negative correlation between the abundance of nrfA and nrfH genes and plant total N content. We found that under N deficiency, Mace demonstrated a higher capacity for DNRA, consistent with its reported NUE. Our findings provide important information that the rhizosphere bacterial DNRA pathway response to N deficiency is different between wheat cultivars.</p
First record of Papuanatula (Papuafiliola) in Australia (Ephemeroptera: Baetidae): reassignment of Platybaetis gagadjuensis Suter, 2001 and biogeographic implications
No full textPlatybaetis gagadjuensis Suter, 2001, an Australian mayfly species originally assigned to the genus Platybaetis Müller-Liebenau, 1980, has long presented morphological inconsistencies with its generic placement. Recent comparative analyses have demonstrated that this species fully corresponds to the newly established subgenus Papuafiliola Kaltenbach, Kluge & Gattolliat, 2025. The description of this subgenus, and its placement within the genus Papuanatula Lugo-Ortiz & McCafferty, 1999, entails a significant revision of the generic concept and diagnostic characters. Accordingly, we formally propose the new combination Papuanatula (Papuafiliola) gagadjuensis comb. nov. This reassignment does not require any modification to the existing diagnoses of the genus or subgenus. Papuanatula (P.) gagadjuensis comb. nov. can be distinguished from the other known species in Papuafiliola by the dark brown pattern on femora, the shape of the femora, the shape of the gills, the degree of development of the thumb-like projection on segment II of the labial palp and the distribution of small unpaired dorsal protuberances on abdominal tergites I–V. This transfer marks the first record of Papuanatula in Australia and extends the known range of Papuafiliola beyond New Guinea. The occurrence of this lineage in northern Australia further supports biogeographical connections between New Guinea and Queensland, already recognized in other mayfly genera such as Caenis Stephens, 1835, Prosopistoma Latreille, 1833 and Labiobaetis Novikova & Kluge, 1987 / Pseudocloeon Klapálek,1905. With the new combination Platybaetis is restricted to the Oriental realm and is absent from Australasia.</p
