Childhood predictors of successful self-reported delinquents
The main aim of this research is to investigate the childhood predictors of successful self-reported delinquents, defined as those who were not convicted. In the Cambridge Study in Delinquent Development (CSDD), 411 London males have been followed up from age 8 to age 61. Self-reported offending was measured for the whole sample for ages 10â14, 15â18, 27â32, and 42â47, for five crimes: burglary, theft of a vehicle, theft from a vehicle, shoplifting, and vandalism. The prevalence of self-reported offending was 64% at ages 10â18 and 11% at ages 27â47, compared with the prevalence of convictions of 23% and 8% respectively. Successful self-reported delinquents were defined as those who offended between ages 10 and 18 but were not convicted up to age 26; 126 successful delinquents were compared with 120 convicted delinquents. Sixteen childhood factors, including attainment, self-control, socioeconomic, parental, family and behavioural factors, predicted successful self-reported delinquents. The most important independent predictors were committing less serious and fewer offences as well as high school attainment, unconvicted parents, low risk-taking, and unseparated families
Service Evaluation of 'Living Well with the Impact of Cancer' Courses
The aim of the Penny Brohn Cancer Care Living Well Service Evaluation was to measure the level of benefit that participants were receiving from the Penny Brohn Cancer Care(PBCC)Living Well course and to inform current and future service provision at PBCC.
The Penny Brohn Whole Person Approach model(PB-WPA model), which underpins the Living Well course, was designed to support the âwhole personâ and the course was
intended to meet the needs of people with cancer, as identified by the National Cancer Survivorship Initiative (NCSI).
The combined qualitative and quantitative results of the Living Well Service Evaluation have demonstrated, very clearly at times, that participants were highly satisfied with the course. The immediate benefit of attending was measurable, in terms of improved health related quality of life (HRQoL) and improved MYCaW (Measure yourself Concerns and Wellbeing) concerns and wellbeing.
The evaluation results show that the Living Well course experience enabled the majority of participants to regain control over many aspects of their life, and to start
taking responsibility for their health. The following aspects of the course were identified as the most helpful:
-Specific units of âeducation and explanationâ about cancer and why healthy lifestyle changes to areas such as diet, exercise and relaxation are beneficial
-Advice and education from medical doctors
-The opportunity to share experiences with other participants
For some, this empowerment led to long-term changes in exercise, food consumption,use of self-help techniques and the ability to communicate more freely and openly with family, friends and medical professionals. These improvements were reflected in the 12 month outcome data, where a sustained improvement in HRQoL and MYCaW concerns
was reported by many clients.
Such patient reported outcome measures (PROMs) are limited in what they can measure, thus qualitative data were also collected to ensure that participants were able
to share their experiences (positive or negative) of the Living Well course, and their subsequent experiences of applying the education and techniques learnt on the
course.
A picture emerged that identified difficulties in sustaining lifestyle changes at around the 3-6 month follow-up. Participants who returned to PBCC within the 12 month follow-up period, however, were more likely to benefit by reporting a greater improvement in HRQoL and MYCaW scores, plus an improved understanding of how to
make and maintain healthy lifestyle changes to suit their individual circumstances.
In regards to the current NCSI priorities, it is hoped that the data reported in this evaluation go some way to informing the following:
-Information and support from the point of diagnosis
-Managing the consequences of treatment
-Promoting recovery
-Sustaining recovery
-Supporting people with active and advanced disease
-Improving survivorship intelligence
Finally, this report demonstrates how a patient-centred model of support can be effectively evaluated to provide relevant, practical and evidence-based information to
commissioners.
Participant satisfaction:
Participants were very satisfied with the course content, course delivery and resources provided which often exceeded their needs and expectations.
Participant outcomes:
The PB-WPA model successfully encompassed and supported all the types of concerns participants arrived with.
The most frequently reported participant concerns were psychological and emotional,about their wellbeing and about their physical health. On average, participants experienced statistically and clinically significant
improvements in their MYCaW concern and wellbeing scores, and total HRQoL scores,which remained improved over the 12 month follow-up. The aspects of HRQoL that were most likely to improve after attending the Living Well
course were spiritual, emotional and functional wellbeing. Supporters had their own profile of concerns, namely psychological and emotional,supporter specific concerns and practical concerns. Concerns were as severely rated as those from participants with a diagnosis of cancer and also showed statistically
significant average improvements throughout the 12 month follow-up.
The small group of participants with metastatic disease reported significant improvements in their MYCaW concern scores, in line with the whole evaluation group,and a significantly greater improvement in HRQoL over 12 months compared to participants with primary cancer.Participants who returned for more support from PBCC were in more need of support than those who did not return. They were more likely to have poorer HRQoL at baseline
and rate their concerns more severely.
Participants who returned to PBCC experienced more improvement in HRQoL that was likely to be clinically significant. These participants also had a greater degree of improvement in their MYCaW concerns, compared to non-returners. Over half of the participants experienced new concerns over the 12 month follow-up period. Concerns were most frequently associated with psychological and emotional
and physical issues. Furthermore, at 12 months, participants were still experiencing arange of health issues
The alternating least-squares algorithm for CDPCA
Clustering and Disjoint Principal Component Analysis (CDP CA) is a constrained principal component analysis recently proposed for clustering of objects and partitioning of variables, simultaneously, which we have implemented in R language. In this paper, we deal in detail with the alternating least-squares algorithm for CDPCA and highlight its algebraic features for constructing both interpretable principal components and clusters of objects. Two applications are given to illustrate the capabilities of this new methodology
Principal Component Analysis with Noisy and/or Missing Data
We present a method for performing Principal Component Analysis (PCA) on
noisy datasets with missing values. Estimates of the measurement error are used
to weight the input data such that compared to classic PCA, the resulting
eigenvectors are more sensitive to the true underlying signal variations rather
than being pulled by heteroskedastic measurement noise. Missing data is simply
the limiting case of weight=0. The underlying algorithm is a noise weighted
Expectation Maximization (EM) PCA, which has additional benefits of
implementation speed and flexibility for smoothing eigenvectors to reduce the
noise contribution. We present applications of this method on simulated data
and QSO spectra from the Sloan Digital Sky Survey.Comment: Accepted for publication in PASP; v2 with minor updates, mostly to

Integrative Whole Person Oncology Care in the UK
The term âwhole person cancer careâ - an approach that addresses the needs of the person as well as treating the disease - is more widely understood in the UK than its synonym âintegrative oncologyâ. The National Health Service (NHS), provides free access to care for all, which makes it harder to prioritise NHS funding of whole person medicine, where interventions may be multi-modal and lacking in cost-effectiveness data. Despite this, around 30% of cancer patients are known to use some form of complementary or alternative medicine (CAM). This is virtually never medically led, and usually without the support or even the knowledge of their oncology teams, with the exception of one or two large cancer centres. UK oncology services are, however, starting to be influenced from three sides; firstly, by well-developed and more holistic palliative care services; secondly, by directives from central government via the sustainable healthcare agenda; and thirdly, by increasing pressure from patient-led groups and cancer charities. CAM remains unlikely to be provided through the NHS, but nutrition, physical activity, mindfulness, and stress management are already becoming a core part of the NHS âLiving With and Beyond Cancerâ agenda. This supports cancer survivors into stratified pathways of care, based on individual, self-reported holistic needs and risk assessments, which are shared between healthcare professionals and patients. Health and Wellbeing events are being built into cancer care pathways, designed to activate patients into self-management and support positive lifestyle change. Those with greater needs can be directed towards appropriate external providers, where many examples of innovative practice exist. These changes in policy and vision for the NHS present an opportunity for Integrative Oncology to develop further and to reach populations who would, in many other countries, remain underserved or hard-to-reach by whole person approaches
Mesoscopic Model for Free Energy Landscape Analysis of DNA sequences
A mesoscopic model which allows us to identify and quantify the strength of
binding sites in DNA sequences is proposed. The model is based on the
Peyrard-Bishop-Dauxois model for the DNA chain coupled to a Brownian particle
which explores the sequence interacting more importantly with open base pairs
of the DNA chain. We apply the model to promoter sequences of different
organisms. The free energy landscape obtained for these promoters shows a
complex structure that is strongly connected to their biological behavior. The
analysis method used is able to quantify free energy differences of sites
within genome sequences.Comment: 7 pages, 5 figures, 1 tabl
The Responsiveness, Content Validity, and Convergent Validity of the Measure Yourself Concerns and Wellbeing (MYCaW) Patient-Reported Outcome Measure
Objective
Measure Yourself Concerns and Wellbeing (MYCaW) is a patient-centred questionnaire that allows cancer patients to identify and quantify the severity of their âConcernsâ and Wellbeing, as opposed to using a pre-determined list. MYCaW administration is brief and aids in prioritising treatment approaches. Our goal was to assess the convergent validity and responsiveness of MYCaW scores over time, the generalisability of the existing qualitative coding framework in different complementary and integrative healthcare settings and content validity.
Methods
Baseline and 6-week follow-up data (n=82) from MYCaW and FACIT-SpEx questionnaires were collected for a service evaluation of the âLiving Well With The Impact of Cancerâ course at Penny Brohn Cancer Care. MYCaW construct validity was determined using Spearman's Rank Correlation test, and responsiveness indices assessed score changes over time. The existing qualitative coding framework was reviewed using a new dataset (n=158) and coverage of concern categories compared to items of existing outcome measures.
Results
Good correlation between MYCaW and FACIT-SpEx score changes were achieved (r= -0.57, pâ„0.01). MYCaW Profile and Concern scores were highly responsive to change: SRM=1.02 and 1.08; effect size=1.26 and 1.22. MYCaW change scores showed the anticipated gradient of change according to clinically relevant degrees of change. Categories including âSpiritualityâ, âweight changeâ and âpractical concernsâ were added to the coding framework to improve generalisability.
Conclusions
MYCaW scores were highly responsive to change, allowing personalized patient outcomes to be quantified; the qualitative coding framework is generalisable across different oncology settings and has broader coverage of patient-identified concerns compared with existing cancer-related patient-reported outcome measures
Using a whole person approach to support people with cancer: a longitudinal, mixed methods service evaluation
Introduction: Improved models of care are needed to meet all the support needs of people with cancer, which encompass psychological, emotional, physical, spiritual, sexual, occupational, social and existential needs. The aim of this paper is to (1) evaluate short and long-term impacts of using a whole person approach to support people with cancer on the Living Well with the Impact of Cancer Course (LWC); (2) use these data to inform strategic decisions about future service provision at Penny Brohn UK.
Methods: Longitudinal mixed-methods service evaluation (n=135). Data collected included health related quality of life (HRQoL) (FACIT-SpEx); Concerns (types and severity - MYCaW); lifestyle behaviour (bespoke questionnaire) and participantsâ experiences over 12 months post course.
Results: Statistically and clinically significant improvements from baseline - 12 months in severity of MYCaW Concerns (n=64; p<0.000) and mean total HRQoL (n=66; p<0.000). The majority of MYCaW concerns were âpsychological and emotionalâ and about participantsâ wellbeing. Spiritual, emotional and functional wellbeing contributed most to HRQoL improvements at 12 months. Barriers to maintaining healthy lifestyle changes included lack of support from family and friends, time constraints, and returning to work. 3-6 months post-course was identified as the time when more support was most likely to be needed.
Conclusions: Using a whole person approach for the LWC enabled the needs of participants to be met, and statistically and clinically significant improvements in HRQoL and MYCaW Concerns were reported. Qualitative data analysis explored how experiencing whole person support enabled participants to make and sustain healthy lifestyle changes associated with improved survivorship. Barriers experienced to making health behaviour change were also identified. These data then informed wider and more person-centred clinical provision to increase the maintenance of positive long-term behaviour changes. Comparison of whole person approaches to cancer treatment and support and standard care are now urgently needed
âLots of little jobsâ â building local skills ecosystems for the precarious worker
âThe world needs a wash and a weekâs rest,â wrote W.H. Auden in his 1947 poem, The Age of Anxiety. Almost three-quarters of a century later, that is the reality for many whose fulltime work ideas have fragmented into several little short-term jobs, exacerbated by COVID19. The polarisation between those who enjoy security and prosperity and those who do not has increased (Allas et al 2020). Scholars have raised concerns over the impact on the (particularly marginalised) worker of the expansion of non-standard employment, poverty cycles, and lack of training and development (Egdell and Beck 2020), resulting in dualisation, the division between workers with stable jobs and insecure jobs (Chung 2018). By marginalised, we refer to workers who tend to be at the lower or outer edge of the labour market in uncertain, unpredictable, and risky work, from the workerâs perspective (Kalleberg 2012). We argue that in light of Brexit, increased poverty, and weak skills development, understanding and involvement by employers in their local ecosystem is even more imperative. A skills ecosystem is a community of interacting living parts comprising producers, consumers, and decomposers and non-living components that define the ecosystemâs environment.
We share the human resource development (HRD) interventions undertaken jointly by a university and a non-governmental organisation (NGO) between 2016 and 2019 within the City of Liverpool. The context of the research in a skills ecosystem is relevant. We worked with a local NGO based in Toxteth, Liverpool, a highly diverse area characterised by very high levels of multiple deprivation (McCurdy 2020). We found little research in HRD that has challenged the life chances of education and training (Simmons et al 2014) for those in the lower socio-economic groups or, indeed, been involved in offering solutions for those in this growing group of workers. We share our understanding of the lived experience of one of the most disadvantaged groups in the UK, the Roma (Cromarty 2019).
Virtually all of the Roma in this study were in irregular, insecure work with high workâlabour ratios. This may infer the participants worked in small, less regulated environments; instead, many worked in FTSE 100 UK companies. Participantsâ work was generally deemed independent (in contractual terms noted as self-employment) and organised through labour market intermediaries, commonly termed agencies, with evidence of some âabusiveâ and âexploitativeâ practice such as poor working conditions, rather than directly with an employer
Damage and repair classification in reinforced concrete beams using frequency domain data
This research aims at developing a new vibration-based damage classification technique that can efficiently be applied to a real-time large data. Statistical pattern recognition paradigm is relevant to perform a reliable site-location damage diagnosis system. By adopting such paradigm, the finite element and other inverse models with their intensive computations, corrections and inherent inaccuracies can be avoided. In this research, a two-stage combination between principal component analysis and Karhunen-Loéve transformation (also known as canonical correlation analysis) was proposed as a statistical-based damage classification technique. Vibration measurements from frequency domain were tested as possible damage-sensitive features. The performance of the proposed system was tested and verified on real vibration measurements collected from five laboratory-scale reinforced concrete beams modelled with various ranges of defects. The results of the system helped in distinguishing between normal and damaged patterns in structural vibration data. Most importantly, the system further dissected reasonably each main damage group into subgroups according to their severity of damage. Its efficiency was conclusively proved on data from both frequency response functions and response-only functions. The outcomes of this two-stage system showed a realistic detection and classification and outperform results from the principal component analysis-only. The success of this classification model is substantially tenable because the observed clusters come from well-controlled and known state conditions
