Health-promoting prisons in the female estate: an analysis of prison inspection data
Abstract Background Women in prison have comparatively greater health needs than men, often compounded by structures and policies within the prison system. The notion of a ‘health-promoting’ prison is a concept which has been put forward to address health inequalities and health deterioration in prisons. It has, however, not been fully discussed in relation to women in prison. The paper aims to distil the learning and evidence in relation to health promotion in female prisons using prison inspection reports of women’s prisons in England and Wales. Methods Prison inspection reports are one way of ascertaining the contemporary situation in prisons. Prison inspections are often unannounced and use a myriad of methods to draw conclusions around various aspects of prison life. Thirteen prison inspection reports were analysed thematically focusing on health promotion within the institutions. Two analysts conducted the work using NVivo 12. Results Five core thematic areas were identified during the analysis of the reports. Saliently, a joined-up approach to health promotion was not a common feature in the prisons and indeed the focus tended to be on screening and ‘lifestyle issues’ rather than a concern for the underlying determinants of health. There was often an absence of a strategic approach to health promotion. There were some good examples of the democratic inclusion of women in prison in shaping services, but this was not widespread and often tokenistic. There were some examples of inequity and the inspection reports from a small number of institutions, illustrated that the health needs of some women remained unmet. Conclusions The paper suggests that there is potentially some work before conditions in women’s prisons could be described as ‘health-promoting’, although there are some examples of individual prisons demonstrating good practice. The health promoting prison movement has, implicitly at least, focused on the needs of men in prison and this has been to the exclusion of the female prison population. This does lead to several challenges and the potential for exacerbating health challenges faced by an already marginalised and vulnerable group. Greater focus on the health promotion needs of women in prison is required
The significance of 'the visit' in an English category-B prison: Views from prisoners, prisoners' families and prison staff
A number of claims have been made regarding the importance of prisoners staying in touch with their family through prison visits, firstly from a humanitarian perspective of enabling family members to see each other, but also regarding the impact of maintaining family ties for successful rehabilitation, reintegration into society and reduced re-offending. This growing evidence base has resulted in increased support by the Prison Service for encouraging the family unit to remain intact during a prisoner’s incarceration. Despite its importance however, there has been a distinct lack of research examining the dynamics of families visiting relatives in prison. This paper explores perceptions of the same event – the visit – from the families’, prisoners’ and prison staffs' viewpoints in a category-B local prison in England. Qualitative data was collected with 30 prisoners’ families, 16 prisoners and 14 prison staff, as part of a broader evaluation of the visitors’ centre. The findings suggest that the three parties frame their perspective of visiting very differently. Prisoners’ families often see visits as an emotional minefield fraught with practical difficulties. Prisoners can view the visit as the highlight of their time in prison and often have many complaints about how visits are handled. Finally, prison staff see visits as potential security breaches and a major organisational operation. The paper addresses the current gap in our understanding of the prison visit and has implications for the Prison Service and wider social policy
Spanning Trees on Lattices and Integration Identities
For a lattice with vertices and dimension equal or higher
than two, the number of spanning trees grows asymptotically
as in the thermodynamic limit. We present exact integral
expressions for the asymptotic growth constant for spanning trees
on several lattices. By taking different unit cells in the calculation, many
integration identities can be obtained. We also give on the
homeomorphic expansion of -regular lattices with vertices inserted on
each edge.Comment: 15 pages, 3 figures, 1 tabl
Prisoners' perspectives on the transition from the prison to the community: Implications for settings-based health promotion
‘It was just like we were a family again’: play as a means to maintain family ties for children visiting an imprisoned parent
Children can find the process of visiting a prison traumatic and as a result of parental incarceration may experience a range of adverse outcomes. When children stay in contact with their imprisoned parent through prison visiting, however, this seems to be a protective factor. This paper reports on a play visits service based at Her Majesty's Prison Leeds, UK. The service provides supervised play work provision for children visiting their father. Data were derived from prisoners and prisoners' families and were triangulated as a means of achieving a level of validity. The findings reveal that play visits do produce positive outcomes for children and play visits are effective in maintaining and strengthening family ties. These effects may be stronger when compared to standard prison visits, but further research is needed to confirm this
A prospective, multicentre, observational cohort study of analgesia and outcome after pneumonectomy
Background Meta-analysis and systematic reviews of epidural compared with paravertebral blockade analgesia techniques for thoracotomy conclude that although the analgesia is comparable, paravertebral blockade has a better short-term side-effect profile. However, reduction in major complications including mortality has not been proven.
Methods The UK pneumonectomy study was a prospective observational cohort study in which all UK thoracic surgical centres were invited to participate. Data presented here relate to the mode of analgesia and outcome. Data were analysed for 312 patients having pneumonectomy at 24 UK thoracic surgical centres in 2005. The primary endpoint was a major complication.
Results The most common type of analgesia used was epidural (61.1%) followed by paravertebral infusion (31%). Epidural catheter use was associated with major complications (odds ratio 2.2, 95% confidence interval 1.1–3.8; P=0.02) by stepwise logistic regression analysis.
Conclusions An increased incidence of clinically important major post-pneumonectomy complications was associated with thoracic epidural compared with paravertebral blockade analgesia. However, this study is unable to provide robust evidence to change clinical practice for a better clinical outcome. A large multicentre randomized controlled trial is now needed to compare the efficacy, complications, and cost-effectiveness of epidural and paravertebral blockade analgesia after major lung resection with the primary outcome of clinically important major morbidity
Exploring concepts of health with male prisoners in three category-C English prisons
Lay understandings of health and illness have a well established track record and a plethora of research now exists which has examined these issues. However, there is a dearth of research which has examined the perspectives of those who are imprisoned. This paper attempts to address this research gap. The paper is timely given that calls have been made to examine lay perspectives in different geographical locations and a need to re-examine health promotion approaches in prison settings. Qualitative data from thirty-six male sentenced prisoners from three prisons in England were collected. The data was analysed in accordance with Attride-Stirling's (2001) thematic network approach. Although the men's perceptions of health were broadly similar to the general population, some interesting findings emerged which were directly related to prison life and its associated structures. These included access to the outdoors and time out of their prison cell, as well as maintaining relationships with family members through visits. The paper proposes that prisoners' lay views should be given higher priority given that prison health has traditionally been associated with medical treatment and the bio-medical paradigm more generally. It also suggests that in order to fulfil the World Health Organization's (WHO) vision of viewing prisons as health promoting settings, lay views should be recognised to shape future health promotion policy and practice
Latent Structures based-Multivariate Statistical Process Control: a paradigm shift
The basic fundamentals of statistical process control (SPC)
were proposed by Walter Shewhart for data-starved production environments
typical in the 1920s and 1930s. In the 21st century, the traditional
scarcity of data has given way to a data-rich environment typical of highly
automated and computerized modern processes. These data often exhibit
high correlation, rank deficiency, low signal-to-noise ratio, multistage and
multiway structures, and missing values. Conventional univariate and multivariate
SPC techniques are not suitable in these environments. This article
discusses the paradigm shift to which those working in the quality improvement
field should pay keen attention. We advocate the use of latent
structure based multivariate statistical process control methods as efficient
quality improvement tools in these massive data contexts. This is a strategic
issue for industrial success in the tremendously competitive global market.This research work was partially supported by the Spanish Ministry of Economy and Competitiveness under the project DPI2011-28112-C04-02.Ferrer, A.

Diffusion of Zn into GaAs and AlGaAs from isothermal Liquid-phase epitaxy solutions
In this work we present results of zinc diffusion in GaAs using the liquid phase epitaxy technique from liquid solutions of Ga‐As‐Zn and Ga‐As‐Al‐Zn. Using silicon‐doped n‐GaAs substrates, working at a diffusion temperature of 850 °C, and introducing a dopant concentration ranging 1018–1019 cm−3, the most important findings regarding the diffusion properties are as follows: (a) zinc concentration in the solid depends on the square root of zinc atomic fraction in the liquid; (b) the diffusion is dominated by the interstitial‐substitutional process; (c) the diffusivity D varies as about C3 in the form D=2.9×10−67C3.05; (d) aluminum plays the role of the catalyst of the diffusion process, if it is introduced in the liquid solution, since it is found that D varies as (γAsXlAs)−1; (e) the zinc interstitial is mainly doubly ionized (Zn++i); (f) the zinc diffusion coefficient in Al0.85 Ga0.15 As is about four times greater than in GaAs; (g) by means of all these results, it is possible to control zinc diffusion processes in order to obtain optimized depth junctions and doping levels in semiconductor device fabrication
