Boundary Crossing: Networked Policing and Emergent “Communities of Practice” in Safeguarding Children

Child safeguarding has come to the forefront of public debate in the UK in the aftermath of a series of highly publicised incidents of child sexual exploitation and abuse. These have exposed the inadequacies and failings of inter-organisational relations between police and key partners. While the discourse of policing partnerships is now accepted wisdom, progress has been distinctly hesitant. This paper contributes to understanding both the challenges and opportunities presented through working across organisational boundaries in the context of safeguarding children. It draws on a study of relations within one of the largest Safeguarding Children partnerships in England, developing insights from Etienne Wenger regarding the potential of ‘communities of practice’ that innovate on the basis of everyday learning through ‘boundary work’. We demonstrate how such networked approaches expose the differential power relations and sites of conflict between organisations but also provide possibilities to challenge introspective cultures and foster organisational learning. We argue that crucial in cultivating effective ‘communities of practice’ are: shared commitment and purpose; relations of trust; balanced exchange of information and resources; mutual respect for difference; and an open and mature dialogue over possible conflicts. Boundary crossing can open opportunities to foster increased reflexivity among policing professionals, prompting critical self-reflection on values, ongoing reassessment of assumptions and questioning of terminology. Yet, there is an inherent tension in that the learning and innovative potential afforded by emergent ‘communities of practice’ derives from the coexistence and interplay between both the depth of knowledge within practices and active boundaries across practices

Phase I study of TP300 in patients with advanced solid tumors with pharmacokinetic, pharmacogenetic and pharmacodynamic analyses

Background: A Phase I dose escalation first in man study assessed maximum tolerated dose (MTD), dose-limiting toxicity (DLT) and recommended Phase II dose of TP300, a water soluble prodrug of the Topo-1 inhibitor TP3076, and active metabolite, TP3011. <p/>Methods: Eligible patients with refractory advanced solid tumors, adequate performance status, haematologic, renal, and hepatic function. TP300 was given as a 1-hour i.v. infusion 3-weekly and pharmacokinetic (PK) profiles of TP300, TP3076 and TP3011 were analysed. Polymorphisms in CYP2D6, AOX1 and UGT1A1 were studied and DNA strand-breaks measured in peripheral blood mononuclear cells (PBMCs). <p/>Results: 32 patients received TP300 at 1, 2, 4, 6, 8, 10, 12 mg/m2. MTD was 10 mg/m2; DLTs at 12 (2/4 patients) and 10 mg/m2 (3/12) included thrombocytopenia and febrile neutropenia; diarrhea was uncommon. Six patients (five had received irinotecan), had stable disease for 1.5-5 months. TP3076 showed dose proportionality in AUC and Cmax from 1--10 mg/m2. Genetic polymorphisms had no apparent influence on exposure. DNA strand-breaks were detected after TP300 infusion. <p/>Conclusions: TP300 had predictable hematologic toxicity, and diarrhea was uncommon. AUC at MTD is substantially greater than for SN38. TP3076 and TP3011 are equi-potent with SN38, suggesting a PK advantage

Growth in ataxia telangiectasia

BACKGROUND: Ataxia telangiectasia (A-T) is a DNA repair disorder that affects multiple body systems. Neurological problems and immunodeficiency are two important features of this disease. At this time, two main severity groups are defined in A-T: classic (the more severe form) and mild. Poor growth is a common problem in classic A-T. An objective of this study was to develop growth references for classic A-T. Another objective was to compare growth patterns in classic A-T and mild A-T with each other and with the general population, using the CDC growth references. A final objective was to examine the effects of chronic infection on height. RESULTS: We found that classic A-T patients were smaller overall, and suffered from height and weight faltering that continued throughout childhood and adolescence. When compared to the CDC growth references, the median heights and weights for both male and female patients eventually fell to or below the 3rd centile on the CDC charts. Height faltering was more pronounced in females. Birthweight was lower in the classic A-T group compared to mild A-T and the general population, whereas birth length was not. Finally, we investigated height and BMI faltering in relation to number of infections and found no association. CONCLUSIONS: Classic A-T appears to affect growth in utero. Although children appear to grow well in very early life, faltering begins early, and is unrelenting

Scrutinising the appeal of volunteer Community Speedwatch to policing leaders in England and Wales: Resources, Responsivity and Responsibilisation

This article focuses on ‘Community Speedwatch’ (CSW) - a particular volunteering approach that has apparently attracted the attention of senior police decision-makers in England and Wales over recent years. It considers the significance of decisions by many Police and Crime Commissioners (PCCs) and Chief Constables to embrace CSW as a response to calls from the public for action against speeding motorists. CSW is apparently an option that ticks many boxes in a new era characterised by the increasing democratic accountability of the police. Whilst frequently promoted using the popular language of ‘empowerment’, ‘localism’, ‘self-help’ or ‘ownership’, and seemingly well-suited to current trends towards the increasing responsibilisation of the public, CSW should not be looked at as a straightforward example of a concerned public gifting their time to a grateful police. Rather than consider the road safety merits of the scheme, this paper views CSW as something of a tool which PCCs and Chief Constables can use to negotiate the often conflicting demands placed upon them in straightened economic circumstances. The paper draws on 22 interviews conducted with PCCs (during their first tenure) and Chief Constables in England and Wales

Enhancing legacy in palliative care: study protocol for a randomized controlled trial of Dignity Therapy focused on positive outcomes

BACKGROUND: Dignity Therapy is a brief psychotherapy that can enhance a sense of legacy while addressing the emotional and existential needs of patients receiving hospice or palliative care. In Dignity Therapy, patients create a formalized “legacy” document that records their most cherished memories, their lessons learned in life, as well as their hopes and dreams for loved ones in the future. To date, this treatment has been studied for its impact on mitigating distress within hospice and palliative care populations and has provided mixed results. This study will instead focus on whether Dignity Therapy enhances positive outcomes in this population. METHODS/DESIGN: In this study, 90 patients with cancer receiving hospice or palliative care will complete a mixed-methods randomized controlled trial of Dignity Therapy (n = 45) versus Supportive Attention (n = 45). The patients will be enrolled in the study for 3 weeks, receiving a total of six study visits. The primary outcomes examine whether the treatment will quantitatively increase levels of positive affect and a sense of life closure. Secondary outcomes focus on gratitude, hope, life satisfaction, meaning in life, resilience, and self-efficacy. Using a fixed, embedded dataset design, this study will additionally use qualitative interviews to explore patients’ perceptions regarding the use of positive outcome measures and whether these outcomes are appropriately matched to their experiences in therapy. DISCUSSION: Dignity Therapy has shown mixed results when evaluating its impact on distress, although no other study to date has solely focused on the potential positive aspects of this treatment. This study is novel in its use of mixed methods assessments to focus on positive outcomes, and will provide valuable information about patients’ direct experiences in this area.

The role of the General Practitioner in weight management in primary care – a cross sectional study in General Practice

BACKGROUND: Obesity has become a global pandemic, considered the sixth leading cause of mortality by the WHO. As gatekeepers to the health system, General Practitioners are placed in an ideal position to manage obesity. Yet, very few consultations address weight management. This study aims to explore reasons why patients attending General Practice appointments are not engaging with their General Practitioner (GP) for weight management and their perception of the role of the GP in managing their weight. METHODS: In February 2006, 367 participants aged between 17 and 64 were recruited from three General Practices in Melbourne to complete a waiting room self - administered questionnaire. Questions included basic demographics, the role of the GP in weight management, the likelihood of bringing up weight management with their GP and reasons why they would not, and their nominated ideal person to consult for weight management. Physical measurements to determine weight status were then completed. The statistical methods included means and standard deviations to summarise continuous variables such as weight and height. Sub groups of weight and questionnaire answers were analysed using the chi2 test of significant differences taking p as < 0.05. RESULTS: The population sample had similar obesity co-morbidity rates to the National Heart Foundation data. 74% of patients were not likely to bring up weight management when they visit their GP. Negative reasons were time limitation on both the patient's and doctor's part and the doctor lacking experience. The GP was the least likely person to tell a patient to lose weight after partner, family and friends. Of the 14% that had been told by their GP to lose weight, 90% had cardiovascular obesity related co-morbidities. GPs (15%) were 4th in the list of ideal persons to manage weight after personal trainer CONCLUSION: Patients do not have confidence in their GPs for weight management, preferring other health professionals who may lack evidence based training. Concurrently, GPs target only those with obesity related co-morbidities. Further studies evaluating GPs' opinions about weight management, effective strategies that can be implemented in primary care and the co-ordination of the team approach need to be done

Local governance in the new Police Scotland:Renegotiating power, recognition and responsiveness

A marked, but by no means universal, trend in Europe over the last decade or so has been the centralization or amalgamation of regional police organizations into larger or single units. Scotland is a case in point, its eight regional services becoming one Police Scotland in April 2013. Although the reform process was relatively consensual, the new organization has been the subject of numerous controversies, some of which reflect an actual or perceived loss of the local in Scottish policing. Drawing on a qualitative study of the emerging local governance arrangements, we explore the negotiated character of large-scale organizational reform, demonstrating that it is best understood as a process not an event. We also argue that appeals to localism are not mere expressions of sentiment and resistance to change. They reflect the particular historical development of policing and public service delivery in Scotland at the level of municipal government, but also strong convictions that policing should be subject to democratic deliberation and should recognize and be responsive to those subject to it – what we argue here are necessary functions of police governance in general

Mutations in protocadherin 15 and cadherin 23 affect tip links and mechanotransduction in mammalian sensory hair cells

Immunocytochemical studies have shown that protocadherin-15 (PCDH15) and cadherin-23 (CDH23) are associated with tip links, structures thought to gate the mechanotransducer channels of hair cells in the sensory epithelia of the inner ear. The present report describes functional and structural analyses of hair cells from Pcdh15av3J (av3J), Pcdh15av6J (av6J) and Cdh23v2J (v2J) mice. The av3J and v2J mice carry point mutations that are predicted to introduce premature stop codons in the transcripts for Pcdh15 and Cdh23, respectively, and av6J mice have an in-frame deletion predicted to remove most of the 9th cadherin ectodomain from PCDH15. Severe disruption of hair-bundle morphology is observed throughout the early-postnatal cochlea in av3J/av3J and v2J/v2J mice. In contrast, only mild-to-moderate bundle disruption is evident in the av6J/av6J mice. Hair cells from av3J/av3J mice are unaffected by aminoglycosides and fail to load with [3H]-gentamicin or FM1-43, compounds that permeate the hair cell's mechanotransducer channels. In contrast, hair cells from av6J/av6J mice load with both FM1-43 and [3H]-gentamicin, and are aminoglycoside sensitive. Transducer currents can be recorded from hair cells of all three mutants but are reduced in amplitude in all mutants and have abnormal directional sensitivity in the av3J/av3J and v2J/v2J mutants. Scanning electron microscopy of early postnatal cochlear hair cells reveals tip-link like links in av6J/av6J mice, substantially reduced numbers of links in the av3J/av3J mice and virtually none in the v2J/v2J mice. Analysis of mature vestibular hair bundles reveals an absence of tip links in the av3J/av3J and v2J/v2J mice and a reduction in av6J/av6J mice. These results therefore provide genetic evidence consistent with PCDH15 and CDH23 being part of the tip-link complex and necessary for normal mechanotransduction

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC

Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways. For the first time, we have used an ion-pair reversed-phase high-performance liquid chromatography ultraviolet (UV)-coupled method to rapidly and simultaneously quantify 12 different nucleotides and nucleosides (adenosine triphosphate, adenosine diphosphate, adenosine monophosphate, adenosine, uridine triphosphate, uridine diphosphate, uridine monophosphate, uridine, guanosine triphosphate, guanosine diphosphate, guanosine monophosphate, guanosine): (1) released from a mouse renal cell line (M1 cortical collecting duct) and (2) in human biological samples (i.e., urine). To facilitate analysis of urine samples, a solid-phase extraction step was incorporated (overall recovery rate ? 98 %). All samples were analyzed following injection (100 ?l) into a Synergi Polar-RP 80 Å (250 × 4.6 mm) reversed-phase column with a particle size of 10 ?m, protected with a guard column. A gradient elution profile was run with a mobile phase (phosphate buffer plus ion-pairing agent tetrabutylammonium hydrogen sulfate; pH 6) in 2-30 % acetonitrile (v/v) for 35 min (including equilibration time) at 1 ml min(-1) flow rate. Eluted compounds were detected by UV absorbance at 254 nm and quantified using standard curves for nucleotide and nucleoside mixtures of known concentration. Following validation (specificity, linearity, limits of detection and quantitation, system precision, accuracy, and intermediate precision parameters), this protocol was successfully and reproducibly used to quantify picomolar to nanomolar concentrations of nucleosides and nucleotides in isotonic and hypotonic cell buffers that transiently bathed M1 cells, and urine samples from normal subjects and overactive bladder patients
