'Does the design of settings where acute care is delivered meet the needs of older people? Perspectives of patients, family carers, and staff

Background: Older people with an acute illness, many of whom are also frail, form a significant proportion of the acute hospital inpatient population. Attention is focusing on ways of improving the physical environment to optimize health outcomes and staff efficiency. Purpose: This paper explores the effects of the physical environment in three acute care settings: Acute Hospital Site, In-patient Rehabilitation Hospital, and Intermediate Care Provision (a nursing home with some beds dedicated to intermediate care) chosen to represent different steps on the acute care pathway for older people and gain the perspectives of patients, family carers and staff. Methods: Semi structured interviews were undertaken with 40 patient/carer dyads (where available) and three staff focus groups were conducted in each care setting with a range of staff. Results: Multiple aspects of the physical environment were reported as important by patients, family carers, and staff. For example, visitors stressed the importance of access and parking; patients valued environments where privacy and dignity were protected; storage space was poor across all sites; security was important to patients but visitors want easy access to wards. Conclusions: The physical environment is a significant component of acute care for older people, many of whom are also frail, but often comes second to organization of care, or relationships between actors in an episode of care

Do Potential Fields Develop Current Sheets Under Simple Compression or Expansion?

The recent demonstration of current singularity formation by Low et al. assumes that potential fields will remain potential under simple expansion or compression (Low 2006, 2007; Janse & Low 2009). An explicit counterexample to their key assumption is constructed. Our findings suggest that their results may need to be reconsidered.Comment: Submitted to AP

Redescription of Anaschisma (Temnospondyli: Metoposauridae) from the Late Triassic of Wyoming and the phylogeny of the Metoposauridae

Metoposaurids are non-marine temnospondyls that are among the most common constituents of Late Triassic deposits, but despite their abundance, the evolutionary relationships of the group are poorly resolved and have not been fully addressed with modern phylogenetic methods. The genus Anaschisma is one of a number of poorly resolved metoposaurid taxa and was erected to describe two species from the Popo Agie Formation (Carnian) in Wyoming: Anaschisma browni and Anaschisma brachygnatha. Since being named, the genus has been repeatedly synonymized and separated with other taxa in the context of broader revisions of the Metoposauridae. At present, Anaschisma is considered to be an indeterminate metoposaurid. Extensive descriptive work of metoposaurids since the erection of Anaschisma in 1905 and the last taxonomic review of the clade in 1993, including the naming of several new taxa and the reappraisal of several others, has generated a sufficiently detailed database through which to re-evaluate the taxonomy of the Metoposauridae as part of the analysis of phylogenetic relationships of Anaschisma. Here we reappraise and redescribe the holotypes of A. browni and A. brachygnatha to determine their taxonomic status and relationships in the context of an updated and revised metoposaurid phylogenetic framework. Anaschisma browni and Anaschisma brachygnatha are synonymized under the former species, as all previously listed diagnostic differences are compatible with intraspecific variation. Additionally, the well-known Koskinonodon perfectus is found to be a junior synonym of Anaschisma browni, which takes taxonomic precedence given its earlier description. Poor phylogenetic resolution of the Metoposauridae is likely the product of marked morphological conservatism within the clade and limited character sampling, although some patterns of regional clustering are apparent from the analysis

Cross-cultural generalizability of social and dimensional comparison effects on reading, math, and science self-concepts for primary school students using the combined PIRLS and TIMSS data

Previous cross-cultural studies of social and dimensional comparison processes forming academic self-concepts (the big-fish-little-pond effect (BFLPE) and Internal-external frame-of-reference (I/E) models) have mostly been based on high-school students and two subject domains. Our study is the first to test the cross-cultural generalizability of both comparison processes across reading, mathematics, and science by combining of the TIMSS and PIRLS 2011 databases (15 OECD countries, 67,386 fourth-graders). Consistent with the I/E model, high achievement in mathematics/reading had positive effects on self-concept in the matching domain but negative effects in the non-matching domain. Extending the I/E model, students engaged in assimilating comparisons between science and reading (i.e., achievement in one subject had positive effects on self-concept in the other) but contrasting comparisons between mathematics and science. Strong BFLPEs (negative effects of class-average achievement on self-concept) were found for mathematics but were smaller for reading and science. The results generalized well across all countries

A multination study of socioeconomic inequality in expectations for progression to higher education: the role of between-school tracking and ability stratification

Persistent inequalities in educational expectations across societies are a growing concern. Recent research has explored the extent to which inequalities in education are due to primary effects (i.e., achievement differentials) versus secondary effects (i.e., choice behaviors net of achievement). We explore educational expectations in order to consider whether variations in primary and secondary effects are associated with country variation in curricular and ability stratification. We use evidence from the PISA 2003 database to test the hypothesis that (a) greater between-school academic stratification would be associated with stronger relationships between socioeconomic status and educational expectations and (b) when this effect is decomposed, achievement differentials would explain a greater proportion of this relationship in countries with greater stratification. Results supported these hypotheses

Physical self-concept changes in a selective sport high school : A longitudinal cohort-sequence analysis of the big-fish-little-pond effect

Elite athletes and nonathletes (N = 1,268) attending the same selective sport high school (4 high school age cohorts, grades 7-10, mean ages varying from 10.9 to 14.1) completed the same physical self-concept instrument 4 times over a 2-year period (multiple waves). We introduce a latent cohort-sequence analysis that provides a stronger basis for assessing developmental stability/change than either cross-sectional (multicohort, single occasion) or longitudinal (single-cohort, multiple occasion) designs, allowing us to evaluate latent means across 10 waves spanning a 5-year period (grades 7-11), although each participant contributed data for only 4 waves, spanning 2 of the 5 years. Consistent with the frame-of-reference effects embodied in the big-fish-little-pond effect (BFLPE), physical self-concepts at the start of high school were much higher for elite athletes than for nonathlete classmates, but the differences declined over time so that by the end of high school there were no differences in the 2 groups. Gender differences in favor of males had a negative linear and quadratic trajectory over time, but the consistently smaller gender differences for athletes than for nonathletes did not vary with time

‘River! that in silence windest’ The place of religion and spirituality in social work assessment: sociological reflections and practical implications

This paper explores the place of religion and spirituality in social work assessment. Place represents a topographic or locational concept that suggests an embeddedness within a physically bounded space, implying here that religion and spirituality are centrally important to the lives of many people and therefore necessarily part of the social work relationship between practitioners and their clients or service users. A range of concepts and implications arising from the idea that religion and spirituality form a necessary part of quotidian social work practice require some discussion. First of all we must recognize that religion and spirituality are often seen as synonyms and we must first discuss this and suggest discrete definitions of each concept. We also need to discuss assessment itself in social work, recognising the power relations and potential for the normative imposition of unspoken and taken-for-granted assumptions in making judgements about vulnerable people’s ecologies and psychologies. This is problematised further when we consider questions of vulnerability – a contested term in itself; who makes someone vulnerable, is it a quality or characteristic or does it reflect something structural, or both? Social work may be considered as a locally contextualized set of processes or moral practices that make statements about assumed vulnerabilities. We are taking this further by asking about religion and spirituality as one aspect of this collection of processes. This may project social work as both homogeneous, transferable and globally understood, an idea we will need to debate. Accepting that all these concepts may be contested and problematic we can move forward to consider ways in which religion and spirituality may be assessed in social work, making reference predominantly to UK and US social work whilst being tentative in making any normative assumptions about this exploration. A number of models will be introduced, drawing out some of the potential meanings and consequences of these for interpersonal relationship and also for people’s spiritual perspectives. A case example of the exclusion of religion and spirituality, notably Christianity, from UK social work in the recent past will be provided. This background prepares us for moving towards a sociological analysis of the state of play

School belonging predicts whether an emerging adult will be not in education, employment, or training (NEET) after school

Children who are excluded from school may end up being excluded from other social institutions. Yet little research has considered whether low school belonging is a risk factor for not being in education, employment, or training after graduation. Using two longitudinal cohorts from Australia (N = 14,082; 51% Boys), we explored this relationship. Controlling for a range of individual and school-level covariates, we found that low school belonging at age 15 is a consistent and practically significant predictor of not in education, employment, or training (NEET) status at ages 16 to 20. We conclude that this relationship is unlikely to be the product of low school belonging lowering the chances of students graduating high school. Rather, low school belonging had a unique association with NEET beyond graduation. Given that NEET represents a range of vulnerabilities, educational policy and practice must find ways for schools to create opportunities for all students to feel included, valued, and accepted.
