Depression in the Profession: Social Workers' Experiences and Perceptions

This study reports the findings of interviews with fifty socialworkers who volunteered to describe their personal experiencesof depression in the workplace. The findings confirm the literatureon the stresses of social work and provide an account of theways in which the social workers sought to reconcile their mentalhealth needs with their role as professionals. The study suggeststhe potential for those working at all levels in social workagencies to support social workers who are experiencing depression.At a time of shortages in the profession in the UK, and of effortsto enable those with mental health problems to remain in orreturn to work, the experiences of those social workers interviewedillustrate the managerial, training and human resource imperativesto provide more supportive workplaces.     

Developing Employment Opportunities for Care Leavers

This article describes an action research project carried out in North West England that aimed to assist Children’s Services Departments and Care Trusts in developing their strategies for supporting care leavers into employment and training. The study found a range of models and approaches that can be utilised to develop local and regional partnerships offering employment and training opportunities designed to meet the needs of care leavers. Relevant questions about the extent to which such opportunities should be ring‐fenced or targeted on particular fields of employment are identified. © 2010 The Author(s).

A novel equivalence probability weighted power prior for using historical control data in an adaptive clinical trial design: A comparison to standard methods

A standard two-arm randomised controlled trial usually compares an intervention to a control treatment with equal numbers of patients randomised to each treatment arm and only data from within the current trial are used to assess the treatment effect. Historical data are used when designing new trials and have recently been considered for use in the analysis when the required number of patients under a standard trial design cannot be achieved. Incorporating historical control data could lead to more efficient trials, reducing the number of controls required in the current study when the historical and current control data agree. However, when the data are inconsistent, there is potential for biased treatment effect estimates, inflated type I error and reduced power. We introduce two novel approaches for binary data which discount historical data based on the agreement with the current trial controls, an equivalence approach and an approach based on tail area probabilities. An adaptive design is used where the allocation ratio is adapted at the interim analysis, randomising fewer patients to control when there is agreement. The historical data are down-weighted in the analysis using the power prior approach with a fixed power. We compare operating characteristics of the proposed design to historical data methods in the literature: the modified power prior; commensurate prior; and robust mixture prior. The equivalence probability weight approach is intuitive and the operating characteristics can be calculated exactly. Furthermore, the equivalence bounds can be chosen to control the maximum possible inflation in type I error.     

Young people's and carers' perspectives on the mental health needs of looked-after adolescents

While the mental health needs of looked‐after young people have been described in a number of clinical studies, the views of looked‐after adolescents themselves concerning their mental health needs have only rarely been reported. This study used focus groups to elicit the ideas and experiences of looked‐after young people in two local authorities in England. Front‐line carers in the region were also surveyed. Young people and carers were agreed in highlighting the damaging effects of the discontinuity and change experienced in the looked‐after system. Young people emphasized the importance of exercising choice and control when seeking and receiving support and identified the value of positive role models provided by ‘survivors’ of the care system. Carers reported high levels of risk behaviour, particularly self‐harm, among young people in children's homes. These differing perspectives need to be openly acknowledged and negotiated within care settings in order that relevant and accessible therapeutic and support services can be offered to looked‐after adolescents.     

Assessing efficacy in important subgroups in confirmatory trials: An example using Bayesian dynamic borrowing

Assessment of efficacy in important subgroups – such as those defined by sex, age, race and region – in confirmatory trials is typically performed using separate analysis of the specific subgroup. This ignores relevant information from the complementary subgroup. Bayesian dynamic borrowing uses an informative prior based on analysis of the complementary subgroup and a weak prior distribution centred on a mean of zero to construct a robust mixture prior. This combination of priors allows for dynamic borrowing of prior information; the analysis learns how much of the complementary subgroup prior information to borrow based on the consistency between the subgroup of interest and the complementary subgroup. A tipping point analysis can be carried out to identify how much prior weight needs to be placed on the complementary subgroup component of the robust mixture prior to establish efficacy in the subgroup of interest. An attractive feature of the tipping point analysis is that it enables the evidence from the source subgroup, the evidence from the target subgroup, and the combined evidence to be displayed alongside each other. This method is illustrated with an example trial in severe asthma where efficacy in the adolescent subgroup was assessed using a mixture prior combining an informative prior from the adult data in the same trial with a non-informative prior.     

Mobilities,mobile work and habitation: truck drivers and the crisis in occupational auto-mobility in the UK

This paper examines the relation between mobilities and mobile work through a focus on occupational auto-mobility and habitation. Drawing on qualitative research conducted on truck drivers/driving in South-east England, it shows habitation emerges when driving stops; that it is cab-based dwelling-in-transit and nomadic dwelling rooted in and bounded by the material culture of the cab; and that it is displaced to the margins and interstices of the road and logistical network. The paper highlights the discomfort of cab-based habitation and its limits, in sanitation, and examines how recent developments at distribution centres intensify discomfort by denying cab-based habitation. These developments recast the relation of occupational auto-mobility and habitation through transient dwelling and are key to understanding the current crisis in labour supply in truck driving.     

Investing in the relationship: practitioners’ relationships with looked‐after children and care leavers in Social Work Practices

Providing more consistent and continuous relationships for looked‐after children and care leavers is a current preoccupation in social work in light of many criticisms of the quality of such relationships. Recommendations for more direct work have spurred new models of service delivery in children's services aimed at improving individual outcomes. Independent Social Work Practices (SWPs), a new organizational model piloted in some areas of England between 2009 and 2012, were established to enable social workers and other practitioners to spend more time in direct work and thus to improve the practitioner/child/young person relationship. This paper uses findings from interviews with 169 children and young people across 11 local authorities and 5 SWPs, undertaken as part of a 3‐year national matched control evaluation of pilot SWPs, to identify key elements of good quality practitioner relationships with children or young people. Focusing on children's and young people's perspectives and experiences, the study demonstrates that more direct work and consistent relationships are valued. The paper deploys Recognition Theory to further understanding of effective practice as defined by children and young people.     

Application of time series models to detect regulatory patterns in nitrogen output of adult rats

The techniques of time series analysis are applied to data on the nitrogen output of adult rats with a view to understanding the underlying mechanism governing daily fluctuations in nitrogen output. The model was fitted to the nitrogen output of rats fed at different protein levels to observe any changes in the parameters. The analysis reveals that an autoregressive model of order one was an adequate fit for the nitrogen-output data when the rats were fed at protein requirement levels, and it undergoes a change at low protein levels. In particular, at the zero protein level, i.e. during the conditions of physiological stress, the nitrogen-output series were random for all the rats. Analysis thus shows that while the autoregressive model implies the existence of a regulatory mechanism underlying a given process, the random series implies conditions of physiological stress, i.e. the breakdown of a regulatory mechanism. This exercise highlights the importance of time series models in the field of physiology.
