A high internal heat flux and large core in a warm Neptune exoplanet.

Interactions between exoplanetary atmospheres and internal properties have long been proposed to be drivers of the inflation mechanisms of gaseous planets and apparent atmospheric chemical disequilibrium conditions1. However, transmission spectra of exoplanets have been limited in their ability to observationally confirm these theories owing to the limited wavelength coverage of the Hubble Space Telescope (HST) and inferences of single molecules, mostly H2O (ref. 2). In this work, we present the panchromatic transmission spectrum of the approximately 750 K, low-density, Neptune-sized exoplanet WASP-107b using a combination of HST Wide Field Camera 3 (WFC3) and JWST Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). From this spectrum, we detect spectroscopic features resulting from H2O (21σ), CH4 (5σ), CO (7σ), CO2 (29σ), SO2 (9σ) and NH3 (6σ). The presence of these molecules enables constraints on the atmospheric metal enrichment (M/H is 10-18× solar3), vertical mixing strength (log10Kzz = 8.4-9.0 cm2 s-1) and internal temperature (>345 K). The high internal temperature is suggestive of tidally driven inflation4 acting on a Neptune-like internal structure, which can naturally explain the large radius and low density of the planet. These findings suggest that eccentricity-driven tidal heating is a critical process governing atmospheric chemistry and interior-structure inferences for most of the cool (<1,000 K) super-Earth-to-Saturn-mass exoplanet population.

A reflective, metal-rich atmosphere for GJ 1214b from its JWST phase curve.

There are no planets intermediate in size between Earth and Neptune in our Solar System, yet these objects are found around a substantial fraction of other stars1. Population statistics show that close-in planets in this size range bifurcate into two classes on the basis of their radii2,3. It is proposed that the group with larger radii (referred to as 'sub-Neptunes') is distinguished by having hydrogen-dominated atmospheres that are a few percent of the total mass of the planets4. GJ 1214b is an archetype sub-Neptune that has been observed extensively using transmission spectroscopy to test this hypothesis5-14. However, the measured spectra are featureless, and thus inconclusive, due to the presence of high-altitude aerosols in the planet's atmosphere. Here we report a spectroscopic thermal phase curve of GJ 1214b obtained with the James Webb Space Telescope (JWST) in the mid-infrared. The dayside and nightside spectra (average brightness temperatures of 553 ± 9 and 437 ± 19 K, respectively) each show more than 3σ evidence of absorption features, with H2O as the most likely cause in both. The measured global thermal emission implies that GJ 1214b's Bond albedo is 0.51 ± 0.06. Comparison between the spectroscopic phase curve data and three-dimensional models of GJ 1214b reveal a planet with a high metallicity atmosphere blanketed by a thick and highly reflective layer of clouds or haze.

Organisational impact on the use of restrictive measures: The perspective of Swedish front-line managers.

BACKGROUND: Restrictive measures (RM) are prevalent in services for people with intellectual disabilities. This study investigates managerial awareness of RM and the nature of organisational supports required to reduce their use. METHOD: A survey asked front-line managers and staff what (RM) were used, their purpose, impact and importance (10-item Likert scales) and what organisational changes were required (free text). Responses were analysed using descriptive methods and content analysis. RESULTS: Managers reported a lower use of RM, compared with staff. According to managers, RM were mainly used to keep service users from harm, their use having a significant impact. Opportunities to change practices were limited by a lack of resources and organisational support. CONCLUSION: Front-line managers seem to lack the capacity to address the use of RM due to organisational drift; limited manager time and opportunity to allocate resources; inadequate environments; and lack of skilled staff, knowledge and relevant professional input.

Improving procedural fidelity of behavioural interventions for people with intellectual and developmental disabilities: A systematic review.

BACKGROUND: Despite its importance within behavioural intervention, it remains unclear how best to achieve high procedural fidelity. This paper reviewed studies on improving procedural fidelity of behavioural interventions for individuals with intellectual and developmental disabilities (IDD). METHOD: A systematic literature search was conducted, which identified 20 studies meeting inclusion criteria. Data were extracted on study design, participant characteristics, intervention, target behaviours, effect sizes, maintenance, generalization and social validity. A quality rating was also applied. RESULTS: A total of 100 participants took part in the included studies. Most participants were teachers working with children in school settings. There was a significant positive correlation between level of procedural fidelity and client outcomes. Feedback was the most commonly employed intervention to improve procedural fidelity. CONCLUSIONS: More research should be conducted in environments with high levels of variability such as community homes to determine how to reach and maintain high levels of procedural fidelity.

An evaluation of staff training in positive behavioural support.

BACKGROUND: Positive Behavioural Support (PBS) has been shown to be effective in minimizing challenging behaviour and improving the lives of people with intellectual disabilities. Training in PBS is an important factor in achieving good coverage in the use of PBS. The aim of this study was to evaluate the impact of training managers of social care services in PBS. METHOD: A year-long training programme in PBS was delivered to 50 managers of community-based services for people with challenging behaviour. Data were collected pre- and post-training, and at six month follow-up. A non-randomized control group design was used. RESULTS: Data demonstrated significant reduction in challenging behaviour. However, there was no change in quality of life for service users. CONCLUSION: Training in PBS can reduce challenging behaviour in people with intellectual disabilities; demonstrating any impact of PBS training on quality of life remains a challenge.

Practice Leadership at the Front Line in Supporting People with Intellectual Disabilities and Challenging Behaviour: A Qualitative Study of Registered Managers of Community-based, Staffed Group homes.

BACKGROUND: The front-line management role in services for people with intellectual disabilities remains rather under-researched. The aim of this study was to examine the experiences of registered managers in services for adults with intellectual disability who exhibit challenging behaviour. METHOD: Interviews, primarily focussed upon staff practice, were conducted with 19 managers of staffed group homes in SE England. Transcripts were analysed using interpretive phenomenological analysis. RESULTS: Five groups of themes emerged: monitoring staff performance, supporting new ways of working, shaping staff performance, influence of external and employing agencies, and importance of participants' personal values and experiences. CONCLUSION: The themes identified contribute to a conceptual framework for thinking about front-line management/practice leadership. The limitations, and potential implications, of the findings are discussed.

Towards the prevention of behavioural and psychiatric disorders in people with intellectual disabilities.

Intervention for behavioural and psychiatric disorders in people with intellectual disabilities often only takes place once these conditions are well established and more resistant to change. As an alternative, this paper promotes a public health prevention model and maps out opportunities for intervention at primary, secondary and tertiary levels. The resulting model is partly derived from generic research into these issues and partly on specific evidence on interventions for people with intellectual disabilities; it also contains more theoretical considerations. The additional research that is necessary to demonstrate the efficacy of the interventions identified is also considered. Central to this proposal is a greater integration of issues for people with intellectual disabilities within much broader policy and research agendas.

High cost residential placements for adults with intellectual disabilities.

BACKGROUND: Concern has been expressed repeatedly about the cost and quality of residential placements for adults with learning disabilities and additional needs. This study sought to identify characteristics of the highest cost placements in the South-East of England. METHOD: Lead learning disability commissioners in the South-East of England were asked to provide information about the five highest cost residential placements that they commissioned for adults with learning disabilities. RESULTS: The average placement cost of £172k per annum disguised wide variation. Individuals placed were mainly young and male with high rates of challenging behaviour and/or autism spectrum disorder. Most placements were in out-of-area residential care. The highest costs were associated with hospital placements and placements for people presenting challenging behaviour. CONCLUSIONS: Young, male adults with learning disability, challenging behaviour and/or autism continue to receive very high cost residential support, often in out-of-area residential care. There remains limited evidence of plans to redirect resources to more local service developments.

Senior manager decision-making and interactions with frontline staff in intellectual disability organisations: A Delphi study.

Very little is known of the activities of the most senior managers in organisations providing social care in the community to people with intellectual disabilities. Yet the importance of the focus and activities of senior managers in directing and supporting staff practice and staff experiences is likely to be central to an organisation's functioning and support provided for staff and service users. This study employed Delphi methodology with a panel of 11 senior managers, mostly chief executives, managing small to very large organisations providing support for people with intellectual disabilities, in the UK. Answering three rounds of questions, senior managers described their face-to-face and non-face-to-face contacts with staff and decision-making. Narrative data were subject to quantitative and thematic analysis. In the last round, themes were subject to quantitative analysis. Most contacts between senior managers and staff were in formal structured contexts and all managers used social media to promote the organisations' ambitions regarding good practice. The panel focused upon accessing and understanding the informal aspects of their organisations and staff factors. Decisions were both short-term reactive and long-term strategic and an effort to link these was felt to improve organisational functioning. A framework for understanding senior managers' activities emerged showing two sources of demands and opportunity, extra-organisational focused upon meeting legal and regulatory demands and intra-organisational focused upon understanding and influencing informal staff practices/experiences and cultures within their organisations.

Functional analysis of the early development of self-injurious behavior: incorporating gene-environment interactions.

The analysis of the early development of self-injurious behavior (SIB) has, to date, reflected the wider distinction between nature and nurture. Despite the status of genetic factors as risk markers for the later development of SIB, a model that accounts for their influence on early behavior-environment relations is lacking. In the current paper we argue that the investigation of gene-environment interactions (GxE) and other forms of gene-environment interplay could potentially enhance current approaches to the study of self-injury. A conceptual model of the early development of SIB based explicitly on such relations is presented. The model is consistent with the basic tenets of functional analysis. Implications for research and the assessment, treatment, and prevention of SIB are discussed.

How common are challenging behaviours amongst individuals with Fragile X Syndrome? A systematic review.

Fragile X Syndrome (FXS) appears to be associated with an increased risk for engaging in challenging behaviour, particularly self-injury, relative to those with mixed aetiology learning disabilities. Such behavioural issues are reported to be of high concern for those providing support. As such, this systematic review aimed to gain further epidemiological data regarding challenging behaviours in individuals with FXS, including: self-injurious behaviour (SIB), hand-biting as a specific topography of SIB, aggression and property destruction. Twenty eight manuscripts were identified which reported the prevalence of a relevant topography of behaviour, with widely varying prevalence estimates. Weighted averages of the prevalence of behaviours were calculated across studies. Comparison of proportions revealed significant gender differences and differences in the prevalence of types of behaviour. It is hoped that this comprehensive overview of data on this clinically significant topic will help to inform and drive future investigation to understand and provide effective intervention for the benefit of those with FXS.

Reducing challenging behaviour of adults with intellectual disabilities in supported accommodation: A cluster randomized controlled trial of setting-wide positive behaviour support.

BACKGROUND: Improving the quality of social care through the implementation of setting-wide positive behaviour support (SWPBS) may reduce and prevent challenging behaviour. METHOD: Twenty-four supported accommodation settings were randomized to experimental or control conditions. Settings in both groups had access to individualized PBS either via the organisation's Behaviour Support Team or from external professionals. Additionally, within the experimental group, social care practice was reviewed and improvement programmes set going. Progress was supported through coaching managers and staff to enhance their performance and draw more effectively on existing resources, and through monthly monitoring over 8-11 months. Quality of support, quality of life and challenging behaviour were measured at baseline and after intervention with challenging behaviour being additionally measured at long-term follow-up 12-18 months later. RESULTS: Following intervention there were significant changes to social care practice and quality of support in the experimental group. Ratings of challenging behaviour declined significantly more in the experimental group and the difference between groups was maintained at follow-up. There was no significant difference between the groups in measurement of quality of life. Staff, family members and professionals evaluated the intervention and its outcomes positively. CONCLUSIONS: Some challenging behaviour in social care settings may be prevented by SWPBS that improves the quality of support provided to individuals.

Incorporating "motivation" into the functional analysis of challenging behavior: on the interactive and integrative potential of the motivating operation.

Sensitivity theory attempts to account for the variability often observed in challenging behavior by recourse to the "aberrant motivation" of people with intellectual and developmental disabilities. In this article, we suggest that a functional analysis based on environmental (challenging environments) and biological (challenging needs) motivating operations provides a more parsimonious and empirically grounded account of challenging behavior than that proposed by sensitivity theory. It is argued that the concept of the motivating operation provides a means of integrating diverse strands of research without the undue inference of mentalistic constructs. An integrated model of challenging behavior is proposed, one that remains compatible with the central tenets of functional analysis.

Impact of practice leadership management style on staff experience in services for people with intellectual disability and challenging behaviour: A further examination and partial replication.

BACKGROUND AND AIMS: Practice leadership (PL) style of frontline management has been shown to be associated with better experiences for staff working with people who may exhibit challenging behaviours (Deveau & McGill, 2014). This study aimed to examine additional staff experience factors with a different, larger sample and to partially replicate the findings of (Deveau & McGill, 2014). METHODS: This study was a survey of staff self-reported data collected as part of a larger study. Information was collected on PL and staff experiences of: stress, turnover, job satisfaction and positive work experiences. RESULTS AND CONCLUSIONS: The results broadly supported Deveau and McGill (2014) and demonstrated an association between PL and greater job satisfaction and positive experiences for staff. Results on staff turnover were inconsistent. The positive impact of PL on staff experience was further supported by this study. Suggestions are made for further research. IMPLICATIONS: These findings suggest further research is needed to examine the potential of interventions in frontline management/leadership practice to improve staff experience of working in challenging environments.

Staff reports of setting events associated with challenging behavior.

This study sought to identify the setting events reported by care staff as more and less likely to be associated with the challenging behaviors of people with intellectual disabilities. Sixty-five staff working with 22 individuals were interviewed using an inventory of putative setting events. Findings were collated to allow identification of those events reported to be associated with increased and decreased likelihood of challenging behavior. Some events were reported as strongly associated with the occurrence of challenging behavior, some as strongly associated with its absence, some as largely "inert," and many as idiosyncratically associated with occurrence, absence, or inertness. Different categories of setting events contributed different relative amounts to reported variation in challenging behavior. The use of the inventory described here, or modified versions, may be a useful way of identifying relationships between setting events and challenging behaviors, which suggest ways in which routine service provision might be modified to help prevent challenging behavior.

Staff reports of setting events associated with challenging behavior.

This study identified the setting events reported by caregivers as more and less likely to be associated with challenging behaviors of people with intellectual disabilities. Sixty-five staff working with 22 individuals were interviewed using a setting event inventory. Some setting events (e.g., being in a crowded room) were reported as strongly associated with challenging behavior, some (e.g., one-to-one support) as strongly associated with its absence. Some (e.g., day of week) were reported to be largely "inert"; many were idiosyncratically associated with occurrence, absence, or inertness. Different categories of setting events contributed different amounts to reported variation in challenging behavior. The inventory described here, or modified versions, may help identify relationships between setting events and challenging behaviors. The relationships reported in this study suggest ways in which service provision might be modified to help prevent challenging behavior.

The motivating operation and negatively reinforced problem behavior: a systematic review.

The concept of motivational operations exerts an increasing influence on the understanding and assessment of problem behavior in people with intellectual and developmental disability. In this systematic review of 59 methodologically robust studies of the influence of motivational operations in negative reinforcement paradigms in this population, we identify themes related to situational and biological variables that have implications for assessment, intervention, and further research. There is now good evidence that motivational operations of differing origins influence negatively reinforced problem behavior, and that these might be subject to manipulation to facilitate favorable outcomes. There is also good evidence that some biological variables warrant consideration in assessment procedures as they predispose the person's behavior to be influenced by specific motivational operations. The implications for assessment and intervention are made explicit with reference to variables that are open to manipulation or that require further research and conceptualization within causal models.

Types of motivating operations in interventions with problem behavior: a systematic review.

A motivating operation (MO) alters both the effectiveness of a stimulus as a reinforcer and the current frequency of all behavior that has been reinforced by that particular stimulus. This article reviews studies that have manipulated a MO during interventions with school-age participants with intellectual disabilities and problem behavior. A systematic review was conducted using the following major electronic databases: PsychInfo, Education Resources Information Center, Science Direct, Blackwell, SAGE, and Medline. A total of 31 published articles representing 55 participants was examined. Findings from this study suggest that the modification of a MO usually has an effect on the problem behavior by either establishing or abolishing its motivation. Furthermore, a relationship was found between the type of MO and the behavioral function identified. The theoretical and practical implications of these findings, limitations of this study and potential issues for future research are discussed.

An indirect examination of the function of problem behavior associated with fragile X syndrome and Smith-Magenis syndrome.

Fragile X syndrome (FXS) and Smith-Magenis syndrome (SMS) are associated with a number of specific topographies of problem behavior. Very few studies have examined the function served by problem behavior in these groups. Using the Questions About Behavioral Function scale Matson and Vollmer (User's guide: questions about behavioral function (QABF). Scientific Publishers Inc., Baton Rouge, LA, 1995) the current study examined group differences in the function of problem behavior displayed by children with FXS and SMS, in comparison to a control group of children with non-specific intellectual and developmental disabilities. Between-group analyses showed children with SMS were more likely to display problem behavior related to physical discomfort. Both within- and between-group analyses showed children with FXS were less likely to display attention-maintained problem behavior. These findings hold implications for the assessment, treatment and prevention of problem behavior associated with both FXS and SMS.

Assessing the social acceptability of the functional analysis of problem behavior.

Although the clinical utility of the functional analysis is well established, its social acceptability has received minimal attention. The current study assessed the social acceptability of functional analysis procedures among 10 parents and 3 teachers of children who had recently received functional analyses. Participants completed a 9-item questionnaire, and results suggested that functional analysis procedures were socially acceptable.
