    PAX genes have been shown to be critically required for the development of specific tissues and organs during embryogenesis. In addition, PAX genes are expressed in a handful of adult tissues where they are thought to play important roles, usually different from those in embryogenesis. A common theme in adult tissues is a requirement for PAX gene expression in adult stem cell maintenance or tissue regeneration. The connections between adult stem cell PAX gene expression and cancer are intriguing, and the literature is replete with examples of PAX gene expression in either situation. Here we systematically review the literature and present an overview of postnatal PAX gene expression in normal and cancerous tissue. We discuss the potential link between PAX gene expression in adult tissue and cancer. In addition, we discuss whether persistent PAX gene expression in cancer is favorable or unfavorable

    The intellectual capital of schools: analysing government policy statements on school improvement in light of a new theorization

    "Ideology without competence is a dangerous vice. But competence without ideology is a limited virtue." (D. Miliband, Minister of State for School Standards, DfES).Opportunistic attempts have been made by successive governments to establish - some would say impose - sets of criteria against which the effectiveness of not-for-profit organisations like schools can be gauged. Most have been subjective: the extent of staff involvement in decision making, the appropriateness of the leadership shown by senior managers, the percentage of inspected classes regarded as ‘good’, and so on. Lately, UK government rhetoric, using a lexicon borrowed from Business and Economics, suggests a willingness to move to new systems of reportage; centred on improvement rather than blame, on critical friendship more than on confrontation. There appears no longer to be the puritanical tendency among policy-makers to adopt measures that cause pain in the belief that they alone can be right, but do they constitute (as critics like Thrupp suggest) a random collection of well-intentioned but poorly theorised policies, or can they be cogently conceptualised into a whole? Previously, improvement measures judged schooling simply, in terms of external stakeholder outcomes, but failed to capture the essence of what it was to be (or what it took to become) a successful improving school. This paper suggests that current government policy, whether knowingly or not, is essentially describing improvement from a different perspective - an internal perspective of ‘Intellectual Capital’. The paper knits together government policy statements on school improvement with a re-conceptualisation of Intellectual Capital specifically designed for schools, offering an imposed coherence to government policy that could potentially change the way we think about inspection

    The development of a theory-based intervention to promote appropriate disclosure of a diagnosis of dementia

    Background: The development and description of interventions to change professional practice are often limited by the lack of an explicit theoretical and empirical basis. We set out to develop an intervention to promote appropriate disclosure of a diagnosis of dementia based on theoretical and empirical work. Methods: We identified three key disclosure behaviours: finding out what the patient already knows or suspects about their diagnosis; using the actual words 'dementia' or 'Alzheimer's disease' when talking to the patient; and exploring what the diagnosis means to the patient. We conducted a questionnaire survey of older peoples' mental health teams (MHTs) based upon theoretical constructs from the Theory of Planned Behaviour (TPB) and Social Cognitive Theory (SCT) and used the findings to identify factors that predicted mental health professionals' intentions to perform each behaviour. We selected behaviour change techniques likely to alter these factors. Results: The change techniques selected were: persuasive communication to target subjective norm; behavioural modelling and graded tasks to target self-efficacy; persuasive communication to target attitude towards the use of explicit terminology when talking to the patient; and behavioural modelling by MHTs to target perceived behavioural control for finding out what the patient already knows or suspects and exploring what the diagnosis means to the patient. We operationalised these behaviour change techniques using an interactive 'pen and paper' intervention designed to increase intentions to perform the three target behaviours. Conclusion : It is feasible to develop an intervention to change professional behaviour based upon theoretical models, empirical data and evidence based behaviour change techniques. The next step is to evaluate the effect of such an intervention on behavioural intention. We argue that this approach to development and reporting of interventions will contribute to the science of implementation by providing replicable interventions that illuminate the principles and processes underlying change.This project is funded by UK Medical Research Council, Grant reference number G0300999.

    What do we know about how to do audit and feedback? Pitfalls in applying evidence from a systematic review

    Get PDF
    BACKGROUND: Improving the quality of health care requires a range of evidence-based activities. Audit and feedback is commonly used as a quality improvement tool in the UK National Health Service [NHS]. We set out to assess whether current guidance and systematic review evidence can sufficiently inform practical decisions about how to use audit and feedback to improve quality of care. METHODS: We selected an important chronic disease encountered in primary care: diabetes mellitus. We identified recommendations from National Institute for Clinical Excellence (NICE) guidance on conducting audit and generated questions which would be relevant to any attempt to operationalise audit and feedback in a healthcare service setting. We explored the extent to which a systematic review of audit and feedback could provide practical guidance about whether audit and feedback should be used to improve quality of diabetes care and, if so, how audit and feedback could be optimised. RESULTS: National guidance suggests the importance of securing the right organisational conditions and processes. Review evidence suggests that audit and feedback can be effective in changing healthcare professional practice. However, the available evidence says relatively little about the detail of how to use audit and feedback most efficiently. CONCLUSION: Audit and feedback will continue to be an unreliable approach to quality improvement until we learn how and when it works best. Conceptualising audit and feedback within a theoretical framework offers a way forward

    Software process reflexivity and business performance: initial results from an empirical study

    Get PDF
    Commercial software development organisations routinely operate in dynamic environments, with various situational factors that affect the software development approach undergoing recurring change. We therefore suggest that process reflexivity - the ability to reflect upon the suitability of a software process for a given context and to adapt the process according to changing situational circumstances – is an important capability for software development organizations.. In support of this position we conducted an exploratory industrial study of software development in practice. An initial analysis of our data suggests that software process reflexivity may exercise a strong influence over business success. Further work is required to fully examine our data, however, initial findings indicate that software process reflexivity is worthy of greater attentio

    Academic Functioning and Mental Health in Adolescence

    The current study examines patterns of academic functioning and mental health in 184 middle school children and the relation of such patterns to their prior and subsequent functioning. Data were collected from children during their second, third, fourth, eighth, and ninth grade school years. Cluster analyses were used to delineate patterns of academic functioning and mental health during eighth grade. The authors examined the relation of these patterns to academic functioning and mental health 1 year later the transition to high school, and then examined the long-term developmental roots of the eighth grade patterns using data collected during elementary school years. Results indicated variegated patterns of academic and emotional functioning at eighth grade and stability in these patterns across the high school transition. Some long-term continuity was found among children showing uniformly positive or negative functioning at eighth grade. Studying child functioning across multiple domains and time periods is discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68127/2/10.1177_0743558499142002.pd

    Explaining the effects of an intervention designed to promote evidence-based diabetes care : a theory-based process evaluation of a pragmatic cluster randomised controlled trial

    Background The results of randomised controlled trials can be usefully illuminated by studies of the processes by which they achieve their effects. The Theory of Planned Behaviour (TPB) offers a framework for conducting such studies. This study used TPB to explore the observed effects in a pragmatic cluster randomised controlled trial of a structured recall and prompting intervention to increase evidence-based diabetes care that was conducted in three Primary Care Trusts in England. Methods All general practitioners and nurses in practices involved in the trial were sent a postal questionnaire at the end of the intervention period, based on the TPB (predictor variables: attitude; subjective norm; perceived behavioural control, or PBC). It focussed on three clinical behaviours recommended in diabetes care: measuring blood pressure; inspecting feet; and prescribing statins. Multivariate analyses of variance and multiple regression analyses were used to explore changes in cognitions and thereby better understand trial effects. Results Fifty-nine general medical practitioners and 53 practice nurses (intervention: n = 55, 41.98% of trial participants; control: n = 57, 38.26% of trial participants) completed the questionnaire. There were no differences between groups in mean scores for attitudes, subjective norms, PBC or intentions. Control group clinicians had 'normatively-driven' intentions (i.e., related to subjective norm scores), whereas intervention group clinicians had 'attitudinally-driven' intentions (i.e., related to attitude scores) for foot inspection and statin prescription. After controlling for effects of the three predictor variables, this group difference was significant for foot inspection behaviour (trial group × attitude interaction, beta = 0.72, p < 0.05; trial group × subjective norm interaction, beta = -0.65, p < 0.05). Conclusion Attitudinally-driven intentions are proposed to be more consistently translated into action than normatively-driven intentions. This proposition was supported by the findings, thus offering an interpretation of the trial effects. This analytic approach demonstrates the potential of the TPB to explain trial effects in terms of different relationships between variables rather than differences in mean scores. This study illustrates the use of theory-based process evaluation to uncover processes underlying change in implementation trials.European Union ReBEQI projec
