Group-based trajectories of potentially preventable hospitalisations among older adults after a hip fracture

SummaryKey predictors of three trajectory group membership of potentially preventable hospitalisations were age, the number of comorbidities, the presence of chronic obstructive pulmonary disease and congestive heart failure, and frailty risk at the occurrence of hip fracture. These predictors of their trajectory group could be used in targeting prevention strategies.PurposeAlthough older adults with hip fracture have a higher risk of multiple readmissions after index hospitalisation, little is known about potentially preventable hospitalisations (PPH) after discharge. This study examined group-based trajectories of PPH during a five-year period after a hip fracture among older adults and identified factors predictive of their trajectory group membership.MethodsThis retrospective cohort study was conducted using linked hospitalisation and mortality data in New South Wales, Australia, between 2013 and 2021. Patients aged ≥ 65 years who were admitted after a hip fracture and discharged between 2014 and 2016 were identified. Group-based trajectory models were derived based on the number of subsequent PPH following the index hospitalisation. Multinominal logistic regression examined factors predictive of trajectory group membership.ResultsThree PPH trajectory groups were revealed among 17,591 patients: no PPH (89.5%), low PPH (10.0%), and high PPH (0.4%). Key predictors of PPH trajectory group membership were age, number of comorbidities, dementia, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), frailty risk, place of incident, surgery, rehabilitation, and length of hospital stay. The high PPH had a higher proportion of patients with ≥ 2 comorbidities (OR: 1.86, 95% confidence interval (CI): 1.04–3.32) and COPD (OR: 2.97, 95%CIs: 1.76–5.04) than the low PPH, and the low and high PPHs were more likely to have CHF and high frailty risk as well as ≥ 2 comorbidities and COPD than the no PPH.ConclusionsIdentifying trajectories of PPH after a hip fracture and factors predictive of trajectory group membership could be used to target strategies to reduce multiple readmissions.

Morality, Social Inclusion, and In-Group Superiority: The Differential Role of Individualizing and Binding Foundations in Perceptions of the Social Identity of In-Group and Out-Group Members.

Research into social identity and morality judgments typically focuses on how the former influences the latter. We approach this theme from the opposite direction, establishing the influence of morality on perceptions of social identity. In three studies, conducted in two cultures, we show that in-group members acting immorally are excluded from the group. Extending this investigation to the overlooked study of out-group-on-out-group behavior, in Studies 2 and 3, we compare perceptions of social inclusion for in-group members following (im)moral behavior toward the in-group with perceptions of out-group members following (im)moral behavior toward the out-group. We show that people treat in-group and out-group members alike with respect to binding morals, which concern preservation and protection of the group, but not individualizing morals, which concern preservation and protection of individual rights. Finally, in Study 3, we confirm the underlying motivating mechanism of reasserting in-group superiority by affirming the positive distinctiveness of one's own group.

Group membership, not diet, structures the composition and functional potential of the gut microbiome in a wild primate.

In a highly socially cohesive and cooperative primate, group membership more strongly predicts gut microbiome composition and function than diet.

Turning a mirror into a window: A duoethnographic study of international student identity

AbstractThis duoethnographical study explores the experiences of the two authors, Joanna and Sarah, as international students in the United States that do not quite fully fit in any of the categories described in research literature. Using a Borderland theoretical approach, the authors explore the in‐between spaces at the intersections of their identities in order to understand their complex experiences as white/wwwhite‐passing international doctoral students in the United States. Applying the Borderland approach to both intersectional and social identity frameworks, this chapter seeks to highlight the intricacies involved in the identity development of international students, especially when group membership is fluid. The results of this duoethnography challenge traditional notions of intersectionality of identity and uncover a dissonance in the identities of both authors.

Who Deserves Aid? Perceptions of Fairness in Contexts of Forced Displacement

How do host communities evaluate the fairness of how economic assistance is distributed between themselves and refugees in low- and middle- income countries? I argue that in these contexts, where host communities are often economically vulnerable, they perceive themselves as more deserving of aid than refugees, despite the fact that refugees are often unable to formally work or move about freely. I draw upon original descriptive and experimental survey data in Kenya to illuminate how members of the host community perceive the fairness of the distribution of economic assistance between themselves and refugees as well as how they assess deservingness of aid along a number of dimensions. The descriptive evidence reveals that what hosts consider a fair distribution of aid between themselves and refugees is vastly different from how they perceive the current distribution. A conjoint experiment provides causal evidence that hosts perceive themselves as more deserving of aid than refugees, but that group membership matters less than marital status, age, and ability when determining deservingness. Counter to expectations, assessments of deservingness of refugees and hosts do not vary based on the level of interaction with refugees or income level.

How adolescents learn to build social bonds: A developmental computational account of social explore-exploit decision-making

Building social bonds is a critical task of adolescence that affords opportunities for learning, identity formation, and social support. Failing to develop close relationships in adolescence hinders adult interpersonal functioning and contributes to problems such as loneliness and depression. During adolescence, increased reward sensitivity and greater social flexibility both contribute to healthy social development, yet we lack a clear theory of how these processes interact to support social functioning. Here, we propose synthesizing these two literatures using a computational reinforcement learning framework that recasts how adolescents pursue and learn from social rewards as a social explore-exploit problem. To become socially skilled, adolescents must balance both their efforts to form individual bonds within specific groups and manage memberships across multiple groups to maximize access to social resources. We draw on insights from sociological studies on social capital in collective networks and neurocognitive research on foraging and cooperation to describe the social explore-exploit dilemma faced by adolescents navigating a modern world with increasing access to diverse resources and group memberships. Our account provides important new directions for examining the dynamics of adolescent behavior in social groups and understanding how social value computations can support positive relationships into adulthood.

Assessing social capital and its impact on economic performance: A comparative study of members and non-members of farmer producer companies in India

Farmer producer companies (FPCs), modern farmer collectives registered under India’s Companies Act, play a crucial role in providing core services like input supply, marketing, technical, and financial support, as well as auxiliary services such as social capital and consultancy, which are linked to higher economic performance and innovation. The study analyzes the levels of social capital among members and non-members of FPCs and their relationship to the economic performance of their members. The data on social capital were collected from 20 FPCs (292 members and 77 non-members) from Maharashtra state of India. Unpaired student T-tests and Mann-Whitney tests were performed to compare the levels of social capital among the members and non-members. OLS regression was performed to understand the difference in social capital and its effect on economic performance. The results reveal that all the indicators of social capital were significantly higher for the members (Mean = 4.27) than for non-members (Mean = 3.14). The social capital indicators related to membership and participation in groups (p-value < 0.10) and the sharing of production and other information (p-value < 0.01) positively affected economic performance. Higher levels of education (p-value < 0.05) and frequent contact with members (p-value < 0.01) positively affected, whereas higher landholding (p-value < 0.10) and years of membership (p-value < 0.01) negatively affected the economic performance of members. As the Indian government plans to add 10,000 FPCs in the next three years, the strategy to increase the social capital of FPCs may enhance the overall resilience and sustainability of rural economies.

Exploring Older Adults' Subjective Views on Aging Positively: Development and Validation of the Positive Aging Scale.

Historically, aging research has focused primarily on health deterioration and negative aspects associated with aging. This has limited the scope of our understanding of the experience of aging and the relationships between aging and well-being from an integrative biopsychosocial perspective. In the same vein, there is a lack of reliable and valid assessments of aging that capture the positive aspects that characterize and improve the subjective experience of this period of life, particularly one that focuses on psychosocial well-being, including meaningful experiences and activities, group memberships, and general abilities. This study presents the development and validation of the Positive Aging Scale (PAS), a novel self-report assessment. This was an online cross-sectional study conducted on 501 UK residents aged ≥60 years. A number of self-reported items and measures of positive aging, general health, well-being, and cognitive functioning were administered to the sample. We used exploratory and confirmatory factor analyses and assessed the dimensionality, reliability, and concurrent criterion-related validity of the PAS. The results suggested that a unidimensional solution represents the data well, with the positive aging factor adequately loading on 8 items, and the solution showing factorial invariance between young-old and old participants (i.e., ≥75 years). Total PAS scores positively correlate with general health, well-being, and cognitive functioning. The PAS demonstrated strong psychometric properties and the findings highlight correlations between the PAS and key outcomes of positive aging, including general health. Implications for research and interventions are discussed.

Social Group Membership, Social Identities, and Mental Health Experiences in Urban Poor Communities in Ghana: A Critical Social Psychology Inquiry.

Social groups and identities significantly influence mental health outcomes, yet their impact in resource-poor communities remains understudied. We explored the role of social group memberships and identities in shaping mental health experiences in two urban poor communities in Ghana. Data from 77 participants were analyzed thematically, revealing widespread engagement in social groups that provide access to both material and symbolic resources. However, these groups also serve as sources of tension and contribute to the stigmatization and marginalization of vulnerable members. Those affected include individuals with severe mental disorders, men experiencing depression, young men involved in substance abuse, family caregivers, migrant and tenant households, and otherwise healthy individuals with recurring psychosocial challenges. The groups exacerbate mental health challenges and restrict access to care among marginalized populations. The findings underscore the need for targeted interventions aimed at enhancing mental health support and reducing stigma in resource-poor settings.

Stimulating the capacity to govern the commons.

The ability to strengthen governance institutions and fisheries restrictions and laws is needed to improve conservation and management of common-pool resources. We evaluated the potential for stimulating change with modest interventions by studying fishing village households before and after a 27-month intervention period in a high-priority coral reef conservation area. Interventions included training in catch monitoring, stock assessment, mapping fishing grounds, microcredit, gender inclusion, theatrical skills, fuel efficient stoves, and participation in the planning of a conservation proposal. There was a background increase in reported formal education, household size, group membership, and household wealth but a decrease in fish consumption and public services. Of conservation importance, the perceived strength of 13 governance institutions and benefits of 6 fisheries restrictions increased over the intervention period. Finally, correspondence between knowledge of and agreement with recent national fisheries laws was moderate to high and positively correlated. The intervention period was stronger than demographic factors that often influence perceptions, such as village, government services, gender, household size, membership in community groups, and age responses. In general, perceptions of strengths of governance and benefits of restrictions increased more among women and youth than adult men respondents. The largest changes in perceptions of increased benefits were among strict restrictions initially ranked low, specifically fisheries closures, parks, and species restrictions. Consequently, capacity building overrode demographic factors common to poor people with limited employment capacity that can have negative perceptions of strict conservation.

Solving online conflicts by sensing the other. The role of social presence and closeness in improving the effectiveness of online intergroup contact

While intergroup contact in online contexts has been acknowledged as effective in reducing stereotypes, prejudice, and discrimination, i.e. intergroup bias, the underlying processes remain unclear. This study focuses on intersubjective processes and tests perceived social presence and closeness, as a means for strengthening the effects of online intergroup contact on attitudes towards the outgroup member and intergroup bias. We conducted a pre-post multigroup (White and Black) study on 267 participants (females n = 162, 60.7%; Mage = 22.19, SD = 4.90) who chatted online with a fictitious outgroup member (online bot). Multigroup path analysis results showed that, regardless of the participant’s membership in the majority group (White people) or minority group (Black people), social presence and closeness, i.e. intersubjective processes occurring during online intergroup contact, are positively related to attitude toward the outgroup member, but not to intergroup bias, which is positively related to attitude toward the outgroup member. Theoretical implications for the literature on online intergroup contact will be discussed.

Inherent linguistic preference outcompetes incidental alignment in cooperative partner choice

Abstract An important quality to assess in others is their cooperativeness. We hypothesized that people use linguistic markers in their partners’ speech as a proxy of their cooperativeness in other tasks: specifically, we predicted that participants would prefer syntactically similar conversation partners as cooperation partners in a monetary game. We found that, indeed, participants preferably selected syntactically similar conversation partners as cooperation partners, but only when the participants could communicate using their naturally preferred constructions. In contrast, when participants were forced to communicate using dispreferred constructions, they rather cooperated with those partners that matched their natural preference than with those that matched their overt linguistic use. This pattern of results was likely driven by participants valuing representational alignment (i.e., being aligned on both linguistic features and their mental representations) more than incidental behavioral alignment (i.e., superficial convergence on similar linguistic features during interaction). This is because representational alignment is a potential indicator of group membership and may be associated with in-group benefits such as reputation, reciprocity and normative behavior. Those benefits may outweigh the benefits of simple behavioral alignment, which could be a potential indicator of others’ willingness to cooperate. This has important implications for communication in intercultural settings where members of diverse linguistic groups negotiate cooperative actions.

“I Cannot Tell Anyone:” There are Many Reasons

ABSTRACT Purpose: The purpose of this study was to investigate variables associated with difficulty disclosing past trauma. Across several prevalence studies, 26% of adults never disclosed childhood abuse until adulthood when they were asked in a research survey or interview question. In this Institutional Review Board approved study, group differences were examined (ability and inability to disclose a traumatic event) as well as predictors for difficulty disclosing past trauma. Method: A non-clinical population (N = 693) was examined to determine prevalence rates and group differences between participants unable to tell someone about a past traumatic event (10%) compared to those who could disclose past traumatic events (90%). Variables included pathological dissociative processing, internalized shame, coping strategies (task, emotion, avoidance), and cumulative trauma exposure. Logistic regression analyses were conducted to determine predicting variables for disclosure difficulties. Findings: The group that had difficulty disclosing a past traumatic event had more cumulative trauma, pathological dissociative processing, emotion-oriented coping, and shame. In the first logistic regression analyses, interpersonal traumatic events were predictors for the inability to disclose a traumatic event (classified 90% of group membership). In the second logistic regression, shame and cumulative traumatic exposure were predicting factors (classified 90% of group membership). Conclusion: Difficulty speaking about a traumatic event was associated with interpersonal adult and childhood traumatic events, more internalized shame, and cumulative trauma exposure. It is recommended that clinicians working with patients with substantial traumatic exposure address shame, pathological dissociative processing, and emotion-oriented coping strategies if they detect trauma disclosure difficulties.

Racial and Ethnic Underserved Populations Prescription Analgesic Use Before and After Lower Extremity Amputation in US Medicare.

Racial disparities exist in access to health care and management of multiple health conditions including chronic pain; however, racial disparities in pre- and postoperative pain management in lower extremity amputation are not well-studied. Our objective was to examine the association between different racial and ethnic groups and prescription opioid and other analgesics use before and after lower extremity amputation. We hypothesize prescription opioid and other analgesic use among Black, Hispanic, and Native American US Medicare beneficiaries undergoing lower extremity amputations will be lower compared to White US Medicare beneficiaries. This retrospective cohort study included a 5% national sample of all Medicare beneficiaries from 2011 to 2015 and 15% national sample of fee-for-service Medicare beneficiaries from 2016 to 2018 undergoing nontraumatic, lower extremity amputations. The exposure of interest was racial and ethnic group membership (ie, Black, Hispanic, Native American, White, and others-with others being the combination of the categories Asian and other) as provided in Medicare claims data. Using multivariable generalized estimating equations with a logistic link to account for repeated measurements over time, we estimated the odds of prescription opioid use within 6 months before and after lower extremity amputation across different racial and ethnic groups separately, adjusting for sociodemographic and health status factors (eg, Elixhauser index). Adjusted odds ratios (aORs) and 95% confidence intervals (95% CI) were reported. Among 16,068 eligible beneficiaries who underwent major and minor amputations (mean age = 65.1 ± 12.7 years; female = 36.1%), 10,107 (62.9%) were White, 3462 (21.5%) were Black, 1959 (12.2%) were Hispanic, 247 (1.5%) were Native American, and 151 (2.9%) were beneficiaries of other races. During the 6 months before lower extremity amputation, Hispanic beneficiaries (aOR, 0.71, 95% CI, 0.65-0.78) and beneficiaries of other races (aOR, 0.60, 95% CI, 0.47-0.76) had significantly lower odds of using prescription opioids compared to White beneficiaries. Similarly, Hispanic beneficiaries (aOR, 0.78, 95% CI, 0.71-0.84) and beneficiaries of other races (aOR, 0.63, 95% CI, 0.51-0.78) were associated with lower odds of opioid use in the 6 months after amputation compared to White beneficiaries. Among fee-for-service Medicare beneficiaries, Hispanic and other (eg, Asian) fee-for-service Medicare beneficiaries had lower odds of prescription opioid use than their White counterparts before and after nontraumatic, lower extremity amputations. Efforts to determine the underlying reasons are needed to ensure equitable health care access.

SOCIO-ECONOMIC ANALYSIS OF SMALLHOLDER PIG PRODUCTION IN SABON GARI LOCAL GOVERNMENT AREA, KADUNA STATE, NIGERIA

Multistage sampling procedures were adopted in this study to select Sabon Gari Local Government Area (LGA), 3 out of 11 wards in the LGA and 49 pig farmers. The aim was to analyze the socio-economic as well as costs and returns of pig production in the LGA. A structured questionnaire was used to generate primary data which were analyzed using descriptive statistics and gross margin analysis. Results showed that majority of the farmers fell within the active productive age of 30-50 years; 67% were males and over 67% were married. The total variable cost (TVC) amounted to N185,000 while the gross income was N539,000 yielding a gross margin of N 354,000 and return on investment of N 2.91. Major constraints identified include shortage of funds and poor pricing of produce. Recommendations proffered include better access to credit and membership of cooperative and farmer groups.

Friendship Network and School Socialization Correlates of Adolescent Ethnic-Racial Identity Development.

Ethnic-racial identity (ERI) development is consequential for youth adjustment and includes exploration, resolution, and affect about the meaning of one's ethnic-racial group membership. Little is known about how identity-relevant experiences, such as ethnic-racial socialization and discrimination in peer relationships and school contexts, catalyze adolescent ERI development. The present study examines how identity-relevant experiences in friend and school contexts (i.e., proportion of same-ethnoracial friends, cultural socialization among friends, friends' ERI dimensions, friends' experiences of ethnoracial discrimination, and school promotion of cultural competence and critical consciousness) are associated with ERI development. A multivariate path model with a sample from four southwestern U.S. schools (N = 717; 50.5% girls; Mage = 13.76; 32% Latinx, 31.5% Multiethnic, 25.7% White, 11% other) was used to test these associations. Findings showed that friend and school predictors of ERI did not differ between early and middle adolescents, but significant differences and similarities emerged in some of these associations between ethnoracially minoritized and White youth. Specifically, friend cultural socialization was positively associated with ERI exploration for ethnoracially minoritized youth only, whereas school critical consciousness socialization was positively linked with ERI exploration only for White youth. Friend cultural socialization and friend network's levels of ERI resolution were positively associated with ERI resolution across both ethnoracial groups. These friend and school socialization associations were documented above and beyond significant contributions of personal ethnoracial discrimination to ERI exploration and negative affect for both ethnoracially minoritized and White youth. These findings expand our understanding of how friend and school socialization mechanisms are associated with adolescent ERI development, which is vital to advancing developmental theory and fostering developmental competences for youth to navigate their multicultural yet socially stratified and inequitable world.

When saying sorry is not enough: The paradox of a political apology offered to Irish mother and baby home survivors

AbstractWhile political apologies cannot undo what has been done, they are often perceived as highly relevant for healing and reconciliation. However, these apologies are often mired in controversy and highly political. While research on political apologies has focused on the role of intergroup relations, limited research has explored the intragroup dynamics involved. The present article explores how the paradoxical features of a political apology to ingroup members have their source in partisanship. The analysis used methods derived from discursive psychology. Using data from six parliamentary statements that were given in response to the political apology offered to Irish mother and baby home survivors, we demonstrated how these speakers constructed and understood the apology and how these constructions relate to their own political positions. Specifically, the apology to mothers and babies is used for political purpose, allowing majority members of government to position the wrongdoings experienced by mothers and babies in the past and to encourage the national collective to move on. Others seeking progressive social change—a parliamentary minority—use the apology to shape a political narrative that demands national collective action. Our work highlights the important role that identity‐based power relations play in confronting historical injustice, and how this may result in a dual schism with people within a nation becoming divided over both the apology and the appropriate response.

A social identity approach to understanding sustainability and environmental behaviours in South Africa

ABSTRACT In recent years, change in behaviour towards the environment has gained prominence as a policy tool to influence positive environmental value. Simultaneously, the role played by social identity in promoting pro-environmental action is gaining recognition. Within this work, the intersection between collective group identity and environmental behaviour has received very little attention. Group norms are considered a strong predictor of pro-environmental behaviour, yet the influence of social identity and collective action on environmental action has not been adequately investigated in a multi-ethnic setting. Within this context, this study examines the affective component of social identity influence on pro-environmental action. More succinctly, this study demonstrates how outgroups and in-groups’ relations and broader sociocultural structures, values, interest, and norms impact environmental and sustainability transitions behaviours. Through interviews with participants across the four dominant social groups in South Africa, this study provides compelling evidence that country-wide expressions of social identity and ingroup dynamics shapes the individual behaviour regarding environmental and sustainability concerns and further strengthen the individual’s perspective for social environmental transformation. This study advances the need for a social-identity centred approach to foster pro-environmental and sustainability outcomes. Highlights The influence that social contexts and social group memberships have on individual perception and behaviour provide important insights to build an empirical base for an inclusive environmental and sustainable action. We applied the theory of social identity to explore these processes and how normative group values and group interest shape environmental behaviour.

Factors influencing nursing student satisfaction in aged care placements: An Australian cross-sectional study

AimThis study aimed to investigate factors influencing nursing students’ satisfaction with aged care placements. BackgroundProviding positive clinical experiences in aged care is crucial for students to learn safe, quality care and to foster a sustainable workforce. DesignCross-sectional study MethodsNursing students in nursing degrees participated in the national placement evaluation survey. A total of 2378 responses were extracted from the national clinical placement evaluation survey in 2023. Using multinomial logistic regression, demographics, academic, placement characteristics and placement education quality (clinical environment and learning support) were investigated in relation to three different levels of students' overall satisfaction (low, moderate, high). ResultsStudents reported overall satisfaction with their clinical placement, with a mean score of 7.9 (SD=2.1) on a 10-point scale. While most students agreed that they had achieved their learning objectives (90.0 %), they reported limited opportunities to interact with the multidisciplinary team (80.0 %). Further, students reported a relatively negative experience with staff, such as willingness to work with students (78.9 %) and being positive role models (78.9 %). Comparing the low satisfaction group to the moderate satisfaction group, male gender, identifying as an indigenous student and higher academic years increased the odds of being ‘least satisfied’, whereas international students, whose first language was not English and those with higher perceived placement education quality scores had lower odds of low satisfaction group membership. Conversely, compared with the moderate satisfaction group, those with the highest satisfaction with their clinical placement had a greater odds of being older, an international student and having higher scores in placement quality for the clinical environment and learning support. This model predicted 58.7 % of students' overall satisfaction. ConclusionsPositive learning experiences in aged care may promote the importance of practice in this area to new graduates. Despite students’ overall positive satisfaction with aged care placements, it is clear there are areas to address: a need to develop a structured approach to enhance aged care clinical experiences, progressive development of learning objectives, enhancing student career preparation and increasing participation in interprofessional collaboration may be useful approaches.

The mediating role of systemic inflammation and moderating role of racialization in disparities in incident dementia

BackgroundExposure to systemic racism is linked to increased dementia burden. To assess systemic inflammation as a potential pathway linking exposure to racism and dementia disparities, we investigated the mediating role of C-reactive protein (CRP), a systemic inflammation marker, and the moderating role of the racialization process in incident dementia.MethodsIn the US Health and Retirement Study (n = 6,908), serum CRP was measured at baseline (2006, 2008 waves). Incident dementia was classified by cognitive tests over a six-year follow-up. Self-reported racialized categories were a proxy for exposure to the racialization process. We decomposed racialized disparities in dementia incidence (non-Hispanic Black and/or Hispanic vs. non-Hispanic white) into 1) the mediated effect of CRP, 2) the moderated portion attributable to the interaction between racialized group membership and CRP, and 3) the controlled direct effect (other pathways through which racism operates).ResultsThe 6-year cumulative incidence of dementia is 12%. Among minoritized participants (i.e., non-Hispanic Black and/or Hispanic), high CRP levels ( ≥ 75th percentile or 4.73μg/mL) are associated with 1.26 (95%CI: 0.98, 1.62) times greater risk of incident dementia than low CRP ( < 4.73μg/mL). Decomposition analysis comparing minoritized versus non-Hispanic white participants shows that the mediating effect of CRP accounts for 3% (95% CI: 0%, 6%) of the racial disparity, while the interaction effect between minoritized group status and high CRP accounts for 14% (95% CI: 1%, 27%) of the disparity. Findings are robust to potential violations of causal mediation assumptions.ConclusionsMinoritized group membership modifies the relationship between systemic inflammation and incident dementia.
