Pollen analysis and vegetional history of the âakeldâ basin
A pollen diagram has been constructed for the Akeld Steads region of the Glen Valley in Northumberland. This diagram provides an interesting variation in the vegetational history of the area. Evidence suggests that although the late post glacial vegetation was similar to that of the rest of the region, Quercus appeared before Ulmus in this area. This feature is contrary to the usual pattern suggested, however, it is seen on other northern diagrams but has not been commented upon by their authors. The persistence of pine in the area until the late Boreal period may beassociated with the Cheviot Hills which overlook the basin. The lack of deposit during the late Boreal and early Atlantic periods may be attributed to local hydrologica conditions prevailing at that time. There is some evidence for the presence of Man In the area from the Boreal period onwards. This evidence comes from the pollen diagram and stratigraphy of the site and is further substantiated by the archaeological discoveries made in the area
A classification of data quality assessment and improvement methods
Data quality (DQ) assessment and improvement in larger
information systems would often not be feasible without using suitable âDQ
methodsâ, which are algorithms that can be automatically executed by
computer systems to detect and/or correct problems in datasets. Currently, these
methods are already essential, and they will be of even greater importance as
the quantity of data in organisational systems grows. This paper provides a
review of existing methods for both DQ assessment and improvement and
classifies them according to the DQ problem and problem context. Six gaps
have been identified in the classification, where no current DQ methods exist,
and these show where new methods are required as a guide for future research
and DQ tool development.This is the accepted manuscript. It's currently embargoed pending publication by Inderscience
A risk based model for quantifying the impact of information quality
Information quality is one of the key determinants of information system success. When information quality is poor, it can cause a variety of risks in an organization. To manage resources for information quality improvement effectively, it is necessary to understand where, how, and how much information quality impacts an organization's ability to successfully deliver its objectives. So far, existing approaches have mostly focused on the measurement of information quality but not adequately on the impact that information quality causes. This paper presents a model to quantify the business impact that arises through poor information quality in an organization by using a risk based approach. It hence addresses the inherent uncertainty in the relationship between information quality and organizational impact. The model can help information managers to obtain quantitative figures which can be used to build reliable and convincing business cases for information quality improvement.EPSRCThis is the author accepted manuscript.

Group-Based Diet and Physical Activity Weight-Loss Interventions: A Systematic Review and Meta-Analysis of Randomised Controlled Trials
This is the author accepted manuscript. The final version is available from Wiley via the DOI in this recordBACKGROUND: Many weight-loss interventions are delivered in groups but evidence on their effectiveness, and characteristics associated with effectiveness, is limited. We synthesised evidence on (1) design and delivery of group-based weight-loss interventions; (2) effectiveness; and (3) associations between intervention characteristics, change techniques, and effectiveness. METHODS: Five online databases were searched to May 2017 for randomised controlled trials (RCTs) of group-based diet and/or physical activity interventions for overweight/obese adults (BMI â„ 25). Intervention characteristics were synthesised narratively. Mean differences (MD) in weight loss were calculated using a random-effects meta-analysis, and sub-group analyses were conducted to identify moderators of effectiveness. RESULTS: Forty-seven RCTs reporting 60 evaluations of group-based interventions were included. MD in weight loss between intervention and control groups was -3.49 [95% CI -4.15, -2.84], -3.44 [-4.23, -2.85], and -2.56 kg [-3.79, -1.33] at follow-ups closest to 6, 12, and 24 months, respectively. Explicitly targeting weight loss, men-only groups providing feedback and dietary goals were significantly associated with greater effectiveness (p < .05). CONCLUSIONS: Diet and physical activity interventions delivered in groups are effective in promoting clinically meaningful weight loss at 12 months. Intervention design and effectiveness vary considerably between studies, and evidence on what optimises the effectiveness of group-based weight-loss interventions remains limited.This work presents independent research funded by the UK National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care of the South West Peninsula (PenCLAHRC), C.

Healthy Parent Carers programme: development and feasibility of a novel group-based health-promotion intervention
This is the final version of the article. Available from BioMed Central via the DOI in this record.Background
Parent carers of disabled children report poor physical health and mental wellbeing. They experience high levels of stress and barriers to engagement in health-related behaviours and with âstandardâ preventive programmes (e.g. weight loss programmes). Interventions promoting strategies to improve health and wellbeing of parent carers are needed, tailored to their specific needs and circumstances.
Methods
We developed a group-based health promotion intervention for parent carers by following six steps of the established Intervention Mapping approach. Parent carers co-created the intervention programme and were involved in all stages of the development and testing. We conducted a study of the intervention with a group of parent carers to examine the feasibility and acceptability. Standardised questionnaires were used to assess health and wellbeing pre and post-intervention and at 2 month follow up. Participants provided feedback after each session and took part in a focus group after the end of the programme.
Results
The group-based Healthy Parent Carers programme was developed to improve health and wellbeing through engagement with eight achievable behaviours (CLANGERS â Connect, Learn, be Active, take Notice, Give, Eat well, Relax, Sleep), and by promoting empowerment and resilience. The manualised intervention was delivered by two peer facilitators to a group of seven parent carers. Feedback from participants and facilitators was strongly positive. The study was not powered or designed to test effectiveness but changes in measures of participantsâ wellbeing and depression were in a positive direction both at the end of the intervention and 2 months later which suggest that there may be a potential to achieve benefit.
Conclusions
The Healthy Parent Carers programme appears feasible and acceptable. It was valued by, and was perceived to have benefited participants. The results will underpin future refinement of the intervention and plans for evaluation.We acknowledge funding from the National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care of the South West Peninsula (PenCLAHRC) and the charity Cerebra.
