Regional Evaluation of Weight Management Programmes for Children and Adults. Commissioned by the Department of Health West Midlands

In response to the increasing prevalence of obesity in children and adolescents, numerous interventions with the potential to reduce obesity levels or associated risk of chronic diseases in children and youths have been implemented across the UK, including the West Midlands. However, few of these interventions have been systematically evaluated and consequently, there is a need to examine their effectiveness. This report outlines an evaluation of seven child weight management programmes that were in place in the West Midlands region during July 2007-July 2009

A Preliminary Investigation of Child, Parent and Programme Leader Reflections on Participation in and Delivery of a Family- Based Weight Intervention Programme.

Childhood obesity is considered to be the greatest public health risk to children today, placing young people at considerable risk for adult obesity and consequent CVD, diabetes, liver dysfunction, and other morbidities (Doro-Altan et al., 2008; Singh et al., 2008). As a result numerous interventions with the potential to reduce obesity levels or associated risk of chronic diseases have been devised (Steinberger et al., 2003; Flynn et al., 2006). Not withstanding the need for further quantitative evaluation of the effect of such interventions, key publications have now called for qualitative evaluations to be undertaken in order to create an evidence base from the views of participants that may highlight why certain interventions may be more, or less successful (National Institute for Health and Clinical Excellence, 2006; Luttikhuis et al., 2009). In response to these very recent calls, this abstract intends to present, from qualitative methods of enquiry, preliminary findings of parent, child and programme leader experiences of, reflections on and future intentions following participation in and delivery of a nationally implemented family-based weight intervention programme in the UK. Data from semi-structured interviews with 6 families who completed the programme in December 2008 and 1 programme leader will be presented. Informal thematic analysis will be utilised to identify emergent themes with data presentation accentuating the qualitative, ‘lived’ experience of the programme and the impact of the various aspects of the intervention on intentions for future behaviours. It is anticipated that the outcomes of this study will help to inform the organisation, content, implementation and nature of future intervention programmes in order to enhance their effectiveness

How Managers Can Predict Customer Retention Rates Through Psychological Profiling.

Managers have become increasingly concerned with the retention of their customers and how they improve their retention rates. Customer Relationship Management (CRM) processes have been implemented to allow managers to profile their customers in terms of their value and risk of defection, and to target customers differently. However, customer profiling is often based solely on customers’ behaviours e.g. level/ type of product consumption or demographic characteristics e.g. age, sex, length of customer relationship. Using my own research within the fitness industry, this paper will highlight the psychological variables which have been measured e.g. satisfaction, brand identification and self-determination and how they can be used to predict intentions to, and defection from, an organisation

Close temporal coupling of neuronal activity and tissue oxygen responses in rodent whisker barrel cortex

Neuronal activity elicits metabolic and vascular responses, during which oxygen is first consumed and then supplied to the tissue via an increase in cerebral blood flow. Understanding the spatial and temporal dynamics of blood and tissue oxygen (To(2)) responses following neuronal activity is crucial for understanding the physiological basis of functional neuroimaging signals. However, our knowledge is limited because previous To(2) measurements have been made at low temporal resolution (>100 ms). Here we recorded To(2) at high temporal resolution (1 ms), simultaneously with co-localized field potentials, at several cortical depths from the whisker region of the somatosensory cortex in anaesthetized rats and mice. Stimulation of the whiskers produced rapid, laminar-specific changes in To(2). Positive To(2) responses (i.e. increases) were observed in the superficial layers within 50 ms of stimulus onset, faster than previously reported. Negative To(2) responses (i.e. decreases) were observed in the deeper layers, with maximal amplitude in layer IV, within 40 ms of stimulus onset. The amplitude of the negative, but not the positive, To(2) response correlated with local field potential amplitude. Disruption of neurovascular coupling, via nitric oxide synthase inhibition, abolished positive To(2) responses to whisker stimulation in the superficial layers and increased negative To(2) responses in all layers. Our data show that To(2) responses occur rapidly following neuronal activity and are laminar dependent

The natural history of chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in the USA, and it remains one of the few diseases that continues to increase its numbers. The development and progression of COPD can vary dramatically between individuals. A low level of lung function remains the cornerstone of COPD diagnosis and is a key predictor of prognosis. Lung function, however, is not the only factor in determining morbidity and mortality related to COPD, with factors such as body mass index, exercise capability and comorbid disease being important predictors of poor outcomes. Exacerbations of COPD are additional important indicators of both quality of life and outcomes in COPD patients. Definitions of exacerbations can vary, ranging from an increase in symptoms to COPD-related hospitalisations and death. COPD exacerbations are more common in patients with lower levels of lung function and may lead to more rapid declines in lung function. Better understanding of the natural history of COPD may lead to better definitions of specific COPD phenotypes, better interventions and improved outcomes

Design of the CART data system for the US Department of Energy's ARM Program

The Department of Energy (DOE) has initiated a major atmospheric research effort to reduce the uncertainties found in general circulation and other models due to the effects of clouds and radiation. The objective of the Atmospheric Radiation Measurement Program (ARM) is to provide an experimental testbed for the study of important atmospheric effects, particularly cloud and radiative processes, and testing parameterizations of the processes for use in atmospheric models. This experimental testbed, known as the Clouds and Radiation Testbed (CART), will include a complex data system, the CART Data Environment (CDE). The major functions of the CDE will be to: acquire environments from instruments and external data sources; perform quality assessments of the data streams; create data streams of known quality to be used as model input compared to model output; execute the models and capture their predictions; and make data streams associated with model tests available to ARM investigators in near real-time. The CDE will also be expected to capture ancillary information ( meta-data'') associated with the data streams, provide data management facilities for design of ARM experiments, and provide for archival data storage. The first section of this paper presents background information on CART. Next the process for the functional design of the system is described, the functional requirements summarized, and the conceptual architecture of the CDE is presented. Finally, the status of the CDE design activities is summarized, and major technical challenges are discussed

Synchronous communication in PLM environments using annotated CAD models

The connection of resources, data, and knowledge through communication technology plays a vital role in current collaborative design methodologies and Product Lifecycle Management (PLM) systems, as these elements act as channels for information and meaning. Despite significant advances in the area of PLM, most communication tools are used as separate services that are disconnected from existing development environments. Consequently, during a communication session, the specific elements being discussed are usually not linked to the context of the discussion, which may result in important information getting lost or becoming difficult to access. In this paper, we present a method to add synchronous communication functionality to a PLM system based on annotated information embedded in the CAD model. This approach provides users a communication channel that is built directly into the CAD interface and is valuable when individuals need to be contacted regarding the annotated aspects of a CAD model. We present the architecture of a new system and its integration with existing PLM systems, and describe the implementation details of an annotation-based video conferencing module for a commercial CAD application.This work was supported by the Spanish Ministry of Economy and Competitiveness and the FEDER Funds, through the ANNOTA project (Ref.

Discrepancies in accelerometer-measured physical activity in children due to cut-point non-equivalence and placement site

This study examined dissonance in physical activity (PA) between two youth-specific hip-derived intensity cut-points for the Actiwatch (AW), and compared PA between hip and wrist placements using site-specific cut-points. Twenty-four children aged 11.2 ± 0.5 years wore the AW on the right hip and non-dominant wrist during a typical school day. Minutes of sedentary behaviour and vigorous activity were greater using Puyau et al. (2002) cut-points, but light, moderate, and moderate-to-vigorous (MVPA) were greater when derived using Puyau et al. (2004) cut-points (P < 0.01). Total hip activity counts were lower than wrist. Sedentary minutes were greater at the hip, but minutes of light, vigorous and MVPA were lower (P < 0.01). Moderate minutes were greater at the hip, but differed only when applying the Puyau et al. (2004) cut-points (P < 0.01). In conclusion, data comparisons between two hip derived AW cut-points and between hip and wrist data are inappropriate. Future researchers using the AW at the hip should present data reduced using both published cut-points. As hip and wrist data differ, the wrist placement is preferable as it will likely increase children's compliance to monitoring protocols due to reduced obtrusiveness compared to the hip

The effect of pedometer step goal, feedback and self-monitoring interventions on accelerometer-measured physical activity in children

This study assessed the utility of 3-week goal-setting, self-monitoring and step-feedback pedometer interventions for increasing physical activity (PA) in children, and the relative impact of individual and group-standardised goals. Three classes of primary school children (n = 68) were randomised to: (a) individual-standardised goal (IS), (b) group-standardised goal (GS) or (c) open pedometer control (CON) groups. PA was assessed via accelerometry (baseline and end-point). There were no main effects for study group, but there was an interaction between time and group for moderate-to-vigorous PA (MVPA), with MVPA time change differing between IS and CON, as MVPA increased in IS but decreased in CON. Mean plots showed MVPA increased in less-active children allocated IS goals, but decreased in GS children. MVPA in more-active children did not change in IS, but declined in GS and CON. Goal-setting, self-monitoring and step-feedback pedometer interventions did not modify PA. Individual-standardised goals may, however, have utility due to mitigating the decline in MVPA in more-active and increasing MVPA in less-active children
