AbstractThis article seeks to explore the way in which key, specifically situated actors within the UK water rescue community understand and perceive challenges relating to navigating policy and practical challenges inherent to their role. Utilizing Lipsky's notion of the ‘street level bureaucrat’, focus groups and interviews were undertaken with water rescue practitioners who bridge the gap between high‐level strategy implementers and ground‐level operational personnel. Utilizing a grounded theory approach, the research uncovered how these operators conceptualize the boundaries in relation to their work, the role of knowledge and knowledge exchange, the nature of the obligation, especially with regard to differences between statutory and voluntary agencies, and in relation to ever‐changing public attitudes towards risk and expectations of a right to be rescued. This was underscored by consistent reference to challenges posed by funding, resourcing and the contingent nature of both political will and public interest in their work. The findings, drawing on these uniquely situated actors, emphasized the importance of practitioners interacting with and knowing one another, in addition to having a shared understanding of the water environment on the coast and inland, as being a key means to navigate the ‘bureaucracy’ of water rescue. The ways in which Lipsky's model can complement contemporary discussions regarding social identity within the emergency response to promote both vertical and horizontal cohesion and clarity are examined.

Published: July 2024

AbstractUnderstanding how animals respond to fire is crucial for conservation efforts in fire‐prone regions across the world. How fire affects animal movement is of particular interest, as it determines access to resources, exposure to risks, and connectivity of populations. We report on observations of the movement patterns and habitat selection of two northern quolls (Dasyurus hallucatus, an endangered marsupial predator), one male and one female, in the Pilbara region of Western Australia. We employed GPS tracking and integrated step selection functions to analyse habitat preferences in relation to fire, and used accelerometry data to assess the energetic costs of using burnt areas. The male northern quoll avoided recently burnt areas, likely due to increased energetic demands and predation risks during the breeding season. In contrast, the female northern quoll neither avoided nor preferred burnt areas, but showed a preference for rocky areas. The female appeared to move through burnt areas to access suitable breeding habitat. The movement patterns observed in the two individuals might reflect a broader pattern of sex‐specific responses to fire, but further research is required to confirm how general the pattern is. Our observations indicate that fire can influence northern quoll movement, with female dependence on rocky areas increasing use of suboptimal habitats, and male avoidance of burnt areas raising potential implications for breeding dispersal and population dynamics. Given the expected increases in fire size and frequency, further research on northern quoll responses to fire in the Pilbara is needed to determine if the pattern we observed is consistent across the broader population.

Published: July 2024

AbstractMigratory patterns of the catfish Genidens genidens in four estuaries along the Brazilian Atlantic coast are reconstructed from otolith Sr/Ca, a salinity proxy, to test estuarine‐dependency. To facilitate interpretation of this proxy in otolith core‐to‐edge profiles, a Sr/Ca Reference Value for High Salinity (RVHSSr/Ca) of 4.88 mmol/mol was established experimentally, from fish specimens reared in water with a salinity level (33 psu) between estuarine and high salinity (marine) water. All wild specimens exhibited otolith Sr/Ca values higher than RVHSSr/Ca, suggesting that G. genidens utilizes environments with marine salinity. Our results reveal highly variable environmental histories, with at least five major habitat usage patterns. Most distinctive among these, we find that (a) fish from Paranaguá Estuarine Complex (PEC) exhibit high intraindividual heterogeneity; (b) most fish (57%) from Guanabara Bay (GB) exhibit prolonged exposure to very high salinities, often exceeding 36.5 psu levels found in some shelf sectors; and (c) some fish from Paraiba do Sul River, GB and PEC exhibit Sr/Ca values below RVHSSr/Ca consistent with estuarine residence. These results suggest that G. genidens is not strictly estuarine‐dependent.
Toward a contemporary understanding of organizational trust in socio‐economic systems: Connecting theoretical perspectives of the management and business ethics literature
Authors: van Rietschoten Erik , van Bommel Koen 
Published: July 2024

AbstractThis paper provides a comprehensive overview of the evolution of 30 years of academic research on organizational trust in socio‐economic practice in the management and business ethics literature. A systematic review of 160 papers published in leading management and business ethics academic journals reveals two interpretations—one based on a transactional, cause‐and‐effect idea of the benefit of trust within relationships (or utilitarian trust), and one based on personal, sincere, and virtuous attributes of character allowing the participant to engage in trusting (or virtuous trust). Our review contributes an analysis of the state of prior research and the literature's intertextual coherence which allows problematization of the current theory and identification of opportunities for further contributions. Future work could be based on the interconnections among these two research traditions, ways to expand the current understanding of utilitarian trust, and proposals for a basic moral framework to support virtuous trust from the perspective of an understanding of trust in the socio‐economic practice in which contemporary trust problems arise. Our reinforcement of the theoretical underpinnings of trust also offers practical guidance as it sheds light on trust's nuanced dimensions in complex organizational and socio‐economic environments.

Published: July 2024

SummaryThe Kids ITP Tools (KIT) is a health‐related quality of life (HRQoL) questionnaire that evaluates quality of life in children with immune thrombocytopenia (ITP). There are three formats: Child Self‐Report, Parent Proxy‐Report and Parent Impact‐Report. This study aimed to develop a domain structure by grouping‐related questions from the questionnaire into domains that independently reflect various aspects of HRQoL. The study was conducted in two phases. Phase 1 involved an online survey distributed to experts to identify conceptual domains for the KIT. Phase 2 utilized a statistical approach to analyse responses from patients with ITP and their families. A revised KIT 2.0 was ultimately developed to aid in treatment decision‐making and monitoring of ITP.

AbstractBackground and PurposeAcute pancreatitis (AP) is associated with acinar cell death and inflammatory responses. Ferroptosis is characterized by an overwhelming lipid peroxidation downstream of metabolic dysfunction, in which NADPH‐related redox systems have been recognized as the mainstay in ferroptosis control. Nevertheless, it remains unknown how ferroptosis is regulated in AP and whether we can target it to restrict AP development.Experimental ApproachMetabolomics were applied to explore changes in metabolic pathways in pancreatic acinar cells (PACs) in AP. Using wild‐type and Ptf1aCreERT2/+IDH2fl/fl mice, AP was induced by caerulein and sodium taurocholate (NaT). IDH2 overexpressing adenovirus was constructed for infection of PACs. Mice or PACs were pretreated with inhibitors of FSP1 or glutathione reductase. Pancreatitis severity, acinar cell injury, mitochondrial morphological changes and pancreatic lipid peroxidation were analysed.Key ResultsUnsaturated fatty acid biosynthesis and the tricarboxylic acid cycle pathways were significantly altered in PACs during AP. Inhibition of ferroptosis reduced mitochondrial damage, lipid peroxidation and the severity of AP. During AP, the NADPH abundance and IDH2 expression were decreased. Acinar cell‐specific deletion of IDH2 exacerbated acinar cell ferroptosis and pancreatic injury. Pharmacological inhibition of NADPH‐dependent GSH/GPX4 and FSP1/CoQ10 pathways abolished the protective effect of IDH2 overexpression on ferroptosis in acinar cells. CoQ10 supplementation attenuated experimental pancreatitis via inhibiting acinar cell ferroptosis.Conclusion and ImplicationsWe identified the IDH2‐NADPH pathway as a novel regulator in protecting against AP via restricting acinar cell ferroptosis. Targeting the pathway and its downstream may shed light on AP treatment.

AbstractHuman dimensions research is valuable to managing human‐wildlife interactions, especially in urban environments where such interactions are common. Survey data, which commonly contain Likert scales and questions, are useful in this field; however, these data can be difficult to analyze with formal modeling approaches. We demonstrate one approach, based on hierarchical Bayesian ordinal regression, to evaluate human‐coyote relationships in Rhode Island, USA. We implemented a survey to collect demographic and sociocultural characteristics of Rhode Island residents and information related to their knowledge of and experiences with coyotes. Our objectives were to assess how these characteristics affected respondents' valuation of and interactions (sightings and incidents) with coyotes. We analyzed 980 surveys from October to December 2020. We found that respondents who had fear of coyotes or experienced an incident between an owned animal and coyote, had the lowest valuation of coyotes. The same demographic of respondents also reported the highest sightings of and incidents with coyote. These results indicate that fearful residents, in addition to pet and livestock owners, are priority targets for disseminating information or programming about coyotes. Our analyses and findings demonstrate how Bayesian ordinal regression can provide clear and appropriate inference from survey data on how groups of people vary in their relationship with wildlife. These results are important in effectively and efficiently allocating resources towards mitigation, education, and management of human‐wildlife interactions.

Published: July 2024

AbstractObjectiveThe present study conducted a meta‐analysis to synthesize the associations between sexual minority stress and relationship satisfaction, as well as to examine actor and partner effects.BackgroundSexual minority individuals in same‐sex couples experience various distinct and chronic stressors related to their stigmatized identities and romantic relationships, and these stressors negatively impact relationship satisfaction. Although there have been two meta‐analyses that sought to examine these influences, some fundamental questions remain unanswered. In particular, the roles of dyadic processes and different types of sexual minority stressors remain unclear.MethodA comprehensive search identified 67 studies with 147 effect sizes representing 24,542 individuals.ResultsThe results revealed a significant small association (r = −.100 to −.188) between sexual minority stressors and relationship satisfaction. Internalized stressors were more strongly associated with relationship satisfaction than other types of sexual minority stressors (e.g., prejudice events and concealment). Dyadic analyses demonstrated a significant actor effect of concealment, experiencing prejudice events, and internalized stressors on relationship satisfaction, with the largest effect size for concealment effects.ConclusionThese findings suggest that sexual minority stressors could potentially contribute to same‐sex relational problems. They also underscore the importance of interdependence (both partners' responses as well as their interaction with sexual minority stressors). This understanding may be instrumental in shaping prevention strategies.ImplicationsThe meta‐analysis emphasizes the nuanced impact of sexual minority stressors on same‐sex relationship satisfaction, highlighting the importance of targeted interventions. It underscores the role of dyadic processes, emphasizing the significance of both partners' responses and interactions with stressors in developing effective prevention strategies for healthier same‐sex relationships.

Published: July 2024

ABSTRACTIntroductionIn 2020, surging cases of COVID‐19 meant that health services had to plan for crisis‐level triage. In the Australian Capital Territory, the Clinical Health Emergency Coordination Centre sought to develop a triage policy in collaboration with a range of consumer, carer and community groups. This study aims to map the collaborative development of the COVID‐19 ICU triage policy onto the principles of co‐production.MethodsInterviews were conducted with facilitators, members of advocacy or consumer groups and clinicians who were involved in the development of the triage policy. Interviews were thematically analysed using both theory‐ and data‐driven approaches to, respectively, draw on the theoretical framework of co‐production, and to explore participants' perspectives relevant to but beyond the scope of this theoretical framework.ResultsThe findings suggest that at each stage of the initiative, there were ways in which the principles of co‐production were met, and ways in which they were not met. One of the fundamental concerns that arose was about whether trying to solve a problem based on resources was compatible with a solution based on human rights.ConclusionLiterature about co‐production has been critiqued for being limited to aspirational concerns, or implying co‐production is easily achievable. The current study contributes to existing research through the application of the theoretical framework of co‐production and exploring ways its aims were met and not met within a system‐level collaboration developing a high‐stakes health policy.Patient or Public ContributionThis study has been conducted and written by researchers working from lived experience perspectives, and other researchers working from traditionally mainstream health disciplines, including psychology and medicine. Further, the study is about patient and public involvement in the development of a health policy. Thus it both embodies and is about non‐tokenistic collaboration between people with lived experience and other health professionals.

Published: July 2024

AbstractThis study explores the structural, radiation, and optical properties of cyclosilicates minerals (CMs), providing comprehensive analyses of molar volumes, densities, band gap values, and effective atomic numbers. The structural properties were found to be dependent on the correlations with the interatomic interactions derived from the analysis of Hirshfeld topological surfaces (HTSs) and their voids. In examining a broad energy spectrum from 0.015 to 15 MeV, the study focuses on mass attenuation coefficient (MAC) and linear mass attenuation coefficient (LAC). Results show that MAC values are the highest for the BaTi(SiO3)3 crystal, highlighting its superior γ‐ray attenuation capabilities among other CMs. The study finds that Hirshfeld volume, and surface ranged between 344.21 and 2640.98 Å3 and 388.91 and 1326.97 Å2, reveals distinct electron density distribution characteristics in CM materials. The study probes the impact of HTSs on structural (113 < Vm < 686 cm3/mol), optical (1.95 < n < 2.38), and radiation shielding (13.0 < LAC < 102.0 1/cm at E = 15.0 keV) values, demonstrating that altering the O…A (A = atom in the CM crystal) interactions align with the charge density, potentially tuning other physical values.
