Unconventional magnetism and residual entropy in La<sub>7</sub>Os<sub>3</sub>O<sub>18</sub>
No full textIn this communication we describe the crystal structure and unusual magnetic properties of La7Os3O18, a new layered osmate with structurally discrete (non-corner-sharing) octahedra containing Os5+ with S = 3/2 and strong spin–orbit coupling. Investigations through powder X-ray diffraction, magnetometry and heat capacity measurements demonstrate that the material undergoes an antiferromagnetic ordering transition at TN = 43 ± 1 K, with a further broad overturn in susceptibility at T ≈ 14 K indicating low dimensional short range magnetic ordering. Curie–Weiss fits give an effective moment of µeff = 3.26µB per Os5+ and Weiss constant of θW ≈ −92 K. Heat capacity data reveal that it is the low temperature feature with which the majority of the magnetic entropy is associated. However, between our lowest temperature of 2 K and well above TN we find only approximately half of the expected magnetic entropy to be released. Magnetisation versus field measurements at low temperature reveal a hysteretic metamagnetic transition above 5 T, further indicating that the magnetism below TN is non-trivial in nature
Rebuilding local support systems - person by person, place by place:international advances in local area coordination
No full textLocal Area Coordination (LAC) has emerged as an evidence based, transformative approach to addressing social challenges across diverse populations and geographical regions. In line with the ‘affirmation’ model of disability and the human rights approach embodied in the UN Convention on the Rights of Persons with Disabilities (UNCRPD), LAC challenges current systems approaches and their focus on tightened eligibility and critical needs rationing. This paper asserts LAC’s alignment with contemporary policy priorities by focussing on citizenship rights, strengths and skills, fostering meaningful relationships, shifting resource towards prevention over crisis response, and nurturing local solutions rather than service-led interventions. Based on continual evaluation, LAC has continued to drive systemic change where it is adopted with fidelity. An international and national leadership network approach supports fidelity of implementation, ongoing research, leadership development and rapid knowledge exchange. LAC stands as a proven model and the international network is ready to meet the challenge

No full textThe changing geographies of ageing and age mixing across urban–rural areas in Scotland, 2011–2022
No full textLike other high-income countries, Scotland is experiencing rapid population ageing, with evidence of spatial polarisation of age groups. This study uses the Scottish Censuses of 2011 and 2022 to understand patterns and trends in the geographies of ageing and age mixing. With attention to urban-rural differences, we examined, at the Data Zone (neighbourhood) level, spatial age segregation and age mixing using the Dissimilarity Index, cumulative proportion calculations, Simpson's Diversity Index and Global and Local Moran's I. This paper contributes new findings on the spatial and temporal patterns of ageing and age mixing in Scotland, with relevance for broader debates on health and social care provision, housing accessibility and equity, and population sustainability. First, it illustrates the stark sub-national variation in geographies of age segregation; second, it demonstrates the value of an analytical and interpretive framework using concepts of urban hierarchy; third, it causes us to rethink typical understandings of ageing and the urban hierarchy. In particular, the analyses reveal high age segregation and low age diversity in urban areas together with the potential polarisation of older- and younger-age areas in some parts of cities; stable age mixing in rural areas (but with decreasing age diversity); and accessible (town and rural) neighbourhoods exhibiting both increasing age segregation and diversity and acting as the lynchpin for understanding the local dynamics of age mixing over the last decade. Attention to spatial nuance also reveals that change in age diversity is spatially clustered. The paper raises questions about the demographic dynamics and social meaning implied by spatially-varied age mixing, with implications for population and community planning in Scotland and elsewhere
(Not) all in this together? Viewing climate change as a question of (in)justice rather than common fate increases collective action
No full textEven among people who agree on the existence and urgency of the climate crisis, different understandings of its causes and consequences prevail. Climate change can be understood primarily as a question of injustice, stressing its unequal effects on privileged and marginalized individuals and groups, but it can also be conceptualized as a common fate, stressing the vulnerability of humanity as a whole. Across four studies (total N = 1402), with activists and general population samples from Germany, Malaysia, and the United Kingdom, we investigated how these different understandings affect participation in political activism against climate change. In line with our predictions, we consistently found that climate injustice appraisals (at the individual, group, and systemic level) positively predicted collective action intentions, whereas common fate perceptions showed no or negative effects. We discuss the implications of our findings for researchers and climate movements, particularly the importance of centering climate (in)justice in mobilizing climate action and the potentially demobilizing effects of common fate narratives.</p
The association between chronic alcohol, cannabis, and opioids use and autobiographical memory impairments:a systematic review
No full textIntroduction: Evidence suggests an association between chronic psychoactivesubstance use and memory deterioration. Autobiographical memory (AM) is oneform of long-term memory that is captured through specific personal information. Exploring potential causes of AM impairment is crucial as these memories shape identity and are important for problem solving and imagining the future. This is the first systematic review to primarily assess the association between chronic psychoactive substance use, including cannabis, alcohol, andopioids, and AM impairment. Additionally, associations between AM performance and secondary outcome measures encompassing mental health, severity and pattern of substance use, cognitive and emotional functions, Theory of Mind and Fading Affect Bias were also explored in this paper. Methods: An extensive literature search was conducted using PRISMA guidelines for systematic reviews and meta-analyses. The review covered articles from 2003 to 2025 obtained from searching 10 global databases. Relevant articles were then screened for eligibility based on the inclusion and exclusion criteria for the systematic review. They were also screened for bias and quality. This resulted in 13 papers being narratively synthesized. Results: The narrative synthesis showed a strong association between the chronic use of different substances (e.g. alcohol, cannabis, opioids) and AM impairments. Those chronically using alcohol, cannabis, and opioids consistently retrieved less specific and more general AMs compared to controls. It could also be postulated that AM impairments may be related to executive dysfunctions caused by the daily consumption of psychoactive substances. However, direct causality cannot beinferred due to the cross-sectional design of the studies pooled for the current review. Summary: Future research needs to expand further the association between chronic psychoactive substance use and AM impairments as this will be clinically relevant for treatment planning in this population

No full textDoes the experience of remembering differentially influence the factual accuracy of recognition, and confidence in its accuracy?
No full textRemembering is typically viewed as unreliable and prone to errors, whereas highly confident recognition memory is often believed to be highly reliable and associated with high recognition accuracy. We evaluated these beliefs using memory for photographs of natural scenes in two studies: recognition memory to examine picture similarity effects in a 2-alternative forced-choice measure, and source memory to examine picture-location associations with a continuous retrieval accuracy measure. Additionally, we assessed the experience of remembering and its influence on judgments of confidence and memory accuracy. High confidence remembering was associated with high accuracy when perceptually or mnemonically similar lures were presented in the item recognition task. However, an association between high confidence and high accuracy was also seen in the absence of remembering for mnemonically similar lures. The confidence-accuracy inversion in the picture similarity task is speculated due to confidently (mis)remembering a similar picture stored in memory. Based on analyses of participant and trial level data, in both studies memory quality was strongly associated with confidence. Importantly, remembering moderated the association between recognition accuracy and confidence judgments, differentially influencing confidence more than it influenced accuracy. Memory quality moderated the association between source accuracy and confidence, the relationship being stronger for images remembered vividly. Our findings have implications for accounts of vividness, confidence, episodic memory, and eyewitness testimony. High confidence recognition may not in all cases reliably imply high accuracy. Highly vivid memories, confidently recollected, may not always be factually accurate
