Living to the range limit: consumer isotopic variation increases with environmental stress

Background: Theoretically, each species’ ecological niche is phylogenetically-determined and expressed spatially as the species’ range. However, environmental stress gradients may directly or indirectly decrease individual performance, such that the precise process delimiting a species range may not be revealed simply by studying abundance patterns. In the intertidal habitat the vertical ranges of marine species may be constrained by their abilities to tolerate thermal and desiccation stress, which may act directly or indirectly, the latter by limiting the availability of preferred trophic resources. Therefore, we expected individuals at greater shore heights to show greater variation in diet alongside lower indices of physiological condition.

Methods: We sampled the grazing gastropod Echinolittorina peruviana from the desert coastline of northern Chile at three shore heights, across eighteen regionally-representative shores. Stable isotope values (δ13C and δ15N) were extracted from E. peruviana and its putative food resources to estimate Bayesian ellipse area, carbon and nitrogen ranges and diet. Individual physiological condition was tracked by muscle % C and % N.

Results: There was an increase in isotopic variation at high shore levels, where E. peruviana’s preferred resource, tide-deposited particulate organic matter (POM), appeared to decrease in dietary contribution, and was expected to be less abundant. Both muscle % C and % N of individuals decreased with height on the shore.

Discussion: Individuals at higher stress levels appear to be less discriminating in diet, likely because of abiotic forcing, which decreases both consumer mobility and the availability of a preferred resource. Abiotic stress might be expected to increase trophic variation in other selective dietary generalist species. Where this coincides with a lower physiological condition, this may be a direct factor in setting their range limit.

Bringing down the walls: Is the notion of ‘promoting shared space’ commensurate with effective transformation of contested places in Belfast?

This article is a reflexive and critical examination of recent empirical research on effective practice in the management and ‘transformation’ of contested urban space at sectarian interfaces in Belfast. By considering the development of interfaces, the areas around them and policy responses to their persistence, the reality of contested space in the context of ‘peace building’ is apparent; with implications for local government as central to the statutory response. Belfast has developed an inbuilt absence of connectivity; where freedom of movement is particularly restricted and separation of contested space is the policy default position. Empirical research findings focus attention on the significance of social and economic regeneration and fall into three specific areas that reflect both long-term concerns within neighbourhoods and the need for adequate policy responses and action ‘on the ground’. Drawing on Elden and Sassen we reconfigure the analytical framework by which interfaces are defined, with implications for policy and practice in post-conflict Belfast. Past and current policy for peace-building in Northern Ireland, and transforming the most contested space, at interfaces in Belfast, is deliberately ambiguous and offers little substance having failed to advance from funding-led linguistic compliance to a sustainable peace-building methodology.

Waiting for International Political Sociology: A Field Guide to Living In-Between

This paper explores the in-between positionality of International Political Sociology (IPS) and offers a field guide to help scholars, students and thinkers embrace this disposition more energetically. It makes the case for a more balanced transdisciplinarity that attends to the international, the political and the social at the same time and in equal measure. The power of this in-between approach is that it forces thinkers in IPS to constantly look at the horrors of our contemporary world without turning away. Through the ambivalent position of the ‘happy wreck’, the paper explores the need to do something about these horrors (e.g. diagnose, act, intervene) while fully acknowledging that such actions always produce new forms of violence and exclusion. To help thinkers in IPS inhabit this challenging space of inquiry more confidently, the paper makes four suggestions: (i) broadening our emotional responses to the horrors of the world; (ii) resisting resolution through non-cathartic dispositions; (iii) pursuing slow research to contest dominant rhetorics of crisis and emergency; and (iv) re-imagining shared conditions of vulnerability.

Risk indicators associated with root decay in independently living older adults

Objective: To determine the risk indicators associated with root caries experience in a cohort of independently living older adults in Ireland.
Methods: The data reported in the present study were obtained from a prospective longitudinal study conducted on the risk factors associated with root caries incidence in a cohort of independently living older adults (n=334). Each subject underwent an oral examination, performed by a single calibrated examiner, to determine the root caries index and other clinical variables. Questionnaires were used to collect data on oral hygiene habits, diet, smoking and alcohol habits and education level. A regression analysis with the outcome variable of root caries experience (no/yes) was conducted.
Results: A total of 334 older adults with a mean age of 69.1 years were examined. 53.3% had at least one filled or decayed root surface. The median root caries index was 3.13 (IQR 0.00, 13.92). The results from the multivariate regression analysis indicated that individuals with poor plaque control (OR 9.59, 95%CI 3.84-24.00), xerostomia (OR 18.49, 95%CI 2.00-172.80), two or more teeth with coronal decay (OR 4.50, 95% CI 2.02-10.02) and 37 or more exposed root surfaces (OR 5.48, 95% CI 2.49-12.01) were more likely to have been affected by root caries.
Conclusions: The prevalence of root caries was high in this cohort. This study suggests a correlation between root caries and the variables poor plaque control, xerostomia, coronal decay (≥2 teeth affected) and exposed root surfaces (≥37). The significance of these risk indicators and the resulting prediction model should be further evaluated in a prospective study of root caries incidence.
Clinical Significance: Identification of risk indicators for root caries in independently living older adults would facilitate dental practitioners to identify those who would benefit most from interventions aimed at prevention.

Othering, blame and shame when working with people living with HIV

Significant advances in HIV treatment has meant that for the majority of patients with HIV they are able to live a normal lifespan. However, HIV remains a highly stigmatizing disease with the potential to significantly impact on ones social identity and sense of self. This paper draws on data from a qualitative study of interviews with five gay men, to explore the experiences of shame in relation to living with HIV. The paper adopts a psychoanalytic lens to highlight the mechanisms of splitting that may be involved at both a social and individual level, and the experience of shame among the participants. The paper aims to use this research data to supplement our understanding of what may be occurring ‘on the couch’ with patients who are living with HIV.

Mindful Living in Older Age: a Pilot Study of a Brief, Community-Based, Positive Aging Intervention

Although mindfulness-based interventions have been successfully used with older adults, there have been few interventions that, (a) are created specifically for older adults, (b) are delivered in the community, and (c) aim to promote ‘successful aging’ (rather than just treating dysfunction/disorder). To this end, the current study piloted a brief ‘positive aging’ intervention, comprising two 150 minute sessions, with six female older adults living in the community. Data were gathered through focus groups that were interwoven throughout the intervention. Using thematic analysis, four main themes were identified: (a) aging as a mixed blessing; (b) understanding mindfulness; (c) the challenges of mindfulness; and (d) the benefits of mindfulness. Overall, the intervention was successful in introducing participants to mindfulness and potentially forming the basis of a longer term practice. However, the study also highlighted important points on the challenges of practising mindfulness, in relation to which the paper makes recommendations pertaining to the teaching of mindfulness with older adults.

Profiles of ageing in the South of Portugal: education and cognitive functioning in elderly persons living in institutionalized and community contexts

The region of the Algarve shows huge differences between the coastline where population in the urban areas grows, and the inland rural areas, in some cases very isolated, which frequently have high ageing indexes. This general scenario, with an elderly population with very different economic and social conditions, frames the ongoing PhD research designed as a cross-sectional study of an intentional sample of elderly persons. The basic theoretical framework departs from the perspective of developmental psychology of life-span and the model of selection, optimisation and compensation for optimal ageing (Baltes & Baltes, 1990; Freund & Baltes, 2002). The present study is a first step in the analysis of empirical data collected in the PhD sample (N=156; age range 65 to 97 years; M = 80.4 years; SD = 7.2 years). Its purpose is to assess the cognitive functioning of participants, screening for cognitive impairment and examine the relations between the cognitive status of the subjects and a number of selected variables including educational level, age, physical activity and living contexts of the subjects. We accessed the cognitive status of the participants with the Portuguese version of Mini Mental State Examination (MMSE) finding a 10.3% prevalence of positive cases with cognitive impairment. The results also show significant relationships between the cognitive status accessed by the MMSE and educational level, professional qualification, age, living arrangement and activity level of the participants. The relationship verified between educational level and cognitive status of the participants was the largest correlation found in the study with the variability in educational level accounting for 44.8% of the variability in MMSE score. This results points in the same direction of several lines of research that corroborate the strong intercorrelation between education and cognitive functioning in old age.

Exploring and Improving Access to Direct Payments by People with Dementia Living in Rural Communities

Direct payments are cash payments made to individuals eligible for social care services which allow them to manage and pay for their own social care rather than receiving it directly from their Local Authority. Research suggests that direct payments can enable people with dementia to stay in their own home for longer, and experience greater choice, flexibility and an improved social life. However, uptake of direct payments is currently low. People living in rural communities may particularly benefit from the additional flexibility offered by direct payments; however they may face difficulties accessing appropriate services. The aim of Phase 1 of the research is to explore the reasons why people with dementia who live in rural communities do or do not gain access to direct payments. This will be achieved through analysis of direct payment uptake data, focus groups with social workers, examination of online discussions about direct payments, and interviews with people with dementia, carers and social workers. Findings will inform Phase 2 of the research: the building and pilot testing of an intervention which can be utilised in rural communities to maximise access to direct payments by people with dementia.

Exploring and Improving Access to Direct Payments by People with Dementia Living in Rural Communities

Direct payments are cash payments made to individuals eligible for social care services which allow them to manage their own social care. Research suggests that direct payments can enable people with dementia to stay in their own home for longer and experience greater choice, flexibility and an improved social life. However uptake of direct payments is currently low. The first objective of this research was to explore the experiences of people with dementia living in rural communities, in relation to their access to direct payments. 26 semi-structured interviews were conducted with people with dementia in receipt of social care services in the community, and their carers and social workers. Focus groups were carried out with two community social work teams. Direct payments appeared to afford particular benefits to people with dementia and to those living in rural communities in terms of flexibility, continuity of care and access to local facilities. However it was found that many service users were daunted by the thought of managing their own social care budget. The second objective of the research was to design and pilot test an intervention aimed at increasing uptake of direct payments by people with dementia. This comprised a session delivered to a team of social workers, aimed at encouraging them to offer combined direct payments to service users as a potentially less daunting alternative to full direct payments. Combined direct payments enable service users to receive part of their social care budget as a direct payment while the remainder is retained and managed by the Local Authority. In order to evaluate the intervention direct payment uptake will be examined for the six-month period before and after the intervention session, and social workers in the intervention team will be interviewed about their experiences of offering combined direct payments to service users.

Research suggests that direct payments can enable people with dementia to stay in their own home for longer and experience greater choice, flexibility and an improved social life. However uptake of direct payments is currently low. There is a lack of research to date in this area which addresses the factors of dementia, ageing and rurality in unison. Therefore the objective of this research was to explore the experiences of people with dementia living in rural communities, in relation to their access to direct payments. 26 semi-structured interviews were conducted with people with dementia in receipt of social care services in the community, and their carers and social workers. Focus groups were carried out with two community social work teams, and existing online discussions regarding direct payments were examined. It was found that direct payments tended to be seen as a fall back option, for example as the only alternative to residential care, or as a potential solution to problems experienced by existing social care service users. Direct payments appeared to afford particular benefits to people with dementia and to those living in rural communities in terms of flexibility, continuity of care and access to local facilities. It is therefore important that this group are enabled to access direct payments; ensuring direct payments are viewed as a positive option by all stakeholders is key to this.
