As newly returned New York Police Commissioner, Bill Bratton’s first task will be to regain the trust of the city’s most heavily policed groups

Last week, Bill Bratton was sworn in as New York City’s police commissioner, as part of the administration of new mayor, Bill de Blasio. David Halle, Andrew A. Beveridge, and Sydney Beveridge, take a closer look at Bill Bratton’s policy success in reducing crime, in both New York and Los Angeles, through the use of the COMPSTAT program and its successors. They write that, now that he has returned to New York, Bratton’s challenge will be to keep crime rates low while reducing the widespread hatred of the police among black residents that has been created by ‘Stop & Frisk’ policies

Does Gaming the System Affect Students' Academic Achievement?

A growing body of evidence suggests that schools use test exemption to game educational accountability systems. However, it is not known whether test exemption affects students' academic progress. Analyzing data from an urban school district in Texas, the authors find that special education students make larger achievement gains when they are tested. Using their most conservative estimates, the effect of being tested is approximately .40 standard deviations in reading and .28 standard deviations in math for grades 3-8. Because special education students are more likely to be minority and poor students and these students are more likely to be exempted than their white and non-poor special education counterparts, the exemption of special education students contributes to the growth of black-white, Hispanic-white, and high-low socioeconomic status achievement gaps

Running records and the automated reconstruction of historical narrative

Die sozialwissenschaftliche Forschung befaßt sich mit dem Studium der Veränderung, obwohl die meisten Wissenschaftler, die quantitative Methoden benutzen - Historiker, Soziologen und auch Wirtschaftswissenschaftler -, bis jetzt nicht in der Lage sind, die Datenquellen voll auszuschöpfen, die erläutern, wie soziale Veränderungen tatsächlich eintreten. Es wird eine Methodologie entwickelt - bekannt als 'laufende Aufzeichungen', die es Forschern erlaubt, nicht nur Datenquellen wie Steuer- und Zensuslisten auszunutzen, die im wesentlichen statisch sind, sondern auch durch Gebrauch des Computers die ungeheure Menge von Material zu nutzen, das die Geschehnisse und Transaktionen des Alltagslebens von weiten Teilen der Bevölkerung festhält - Quellen, die den Prozeß der Veränderung selbst dokumentieren, sowie er sich auf bestehende Strukturen und Institutionen bezieht. (KWübers.)'All social science research is concerned with the study of change, yet most scholars who use quantitative methods - historians, sociologists, and economists alike - have been unable to exploit fully data sources which illuminate how social change actually occurs. We have developed a methodology, known as 'running records' (1), which allows researchers not only to use data sources, such as census schedules and tax lists which are essentially static, but also by exploiting the power of the computer, to utilize the vast of materials which record the events and transactions of everyday life for large populations - sources which document the process of change itself, as it relates to existing structures and institutions.'

The tumor suppressor miR-642a-5p targets Wilms tumor 1 gene and cell-cycle progression in prostate cancer

RNA-based therapeutics are emerging as innovative options for cancer treatment, with microRNAs being attractive targets for therapy development. We previously implicated microRNA-642a-5p (miR-642a-5p) as a tumor suppressor in prostate cancer (PCa), and here we characterize its mode of action, using 22Rv1 PCa cells. In an in vivo xenograft tumor model, miR-642a-5p induced a significant decrease in tumor growth, compared to negative control. Using RNA-Sequencing, we identified gene targets of miR-642a-5p which were enriched for gene sets controlling cell cycle; downregulated genes included Wilms Tumor 1 gene (WT1), NUAK1, RASSF3 and SKP2; and upregulated genes included IGFBP3 and GPS2. Analysis of PCa patient datasets showed a higher expression of WT1, NUAK1, RASSF3 and SKP2; and a lower expression of GPS2 and IGFBP3 in PCa tissue compared to non-malignant prostate tissue. We confirmed the prostatic oncogene WT1, as a direct target of miR-642a-5p, and treatment of 22Rv1 and LNCaP PCa cells with WT1 siRNA or a small molecule inhibitor of WT1 reduced cell proliferation. Taken together, these data provide insight into the molecular mechanisms by which miR-642a-5p acts as a tumor suppressor in PCa, an effect partially mediated by regulating genes involved in cell cycle control; and restoration of miR-642-5p in PCa could represent a novel therapeutic approach

Enablers and Barriers to Implementing ICU Follow-Up Clinics and Peer Support Groups Following Critical Illness: The Thrive Collaboratives

OBJECTIVES: Data are lacking regarding implementation of novel strategies such as follow-up clinics and peer support groups, to reduce the burden of postintensive care syndrome. We sought to discover enablers that helped hospital-based clinicians establish post-ICU clinics and peer support programs, and identify barriers that challenged them. DESIGN: Qualitative inquiry. The Consolidated Framework for Implementation Research was used to organize and analyze data. SETTING: Two learning collaboratives (ICU follow-up clinics and peer support groups), representing 21 sites, across three continents. SUBJECTS: Clinicians from 21 sites. MEASUREMENT AND MAIN RESULTS: Ten enablers and nine barriers to implementation of "ICU follow-up clinics" were described. A key enabler to generate support for clinics was providing insight into the human experience of survivorship, to obtain interest from hospital administrators. Significant barriers included patient and family lack of access to clinics and clinic funding. Nine enablers and five barriers to the implementation of "peer support groups" were identified. Key enablers included developing infrastructure to support successful operationalization of this complex intervention, flexibility about when peer support should be offered, belonging to the international learning collaborative. Significant barriers related to limited attendance by patients and families due to challenges in creating awareness, and uncertainty about who might be appropriate to attend and target in advertising. CONCLUSIONS: Several enablers and barriers to implementing ICU follow-up clinics and peer support groups should be taken into account and leveraged to improve ICU recovery. Among the most important enablers are motivated clinician leaders who persist to find a path forward despite obstacles

Financial control, blame avoidance and Radio Caroline: Talkin’ ‘bout my generation

This research examines the use of financial mechanisms that simultaneously impose controls and facilitate blame avoidance by public office-holders. A qualitative historical examination is used to examine legislation designed to prevent Radio Caroline, a pirate radio station, from broadcasting into Britain in the 1960s. Radio Caroline made a mockery of the British Government’s power to manage radio through a monopolist, the British Broadcasting Corporation. In addition, Radio Caroline played the type of rock music the British Government sought to suppress as representing the undesirable side of youth culture. This research examines the suppression of Radio Caroline through the Marine & Broadcasting (Offences) Act (UK) 1967 and the legislative scapegoating of Radio Caroline by targeting its revenue-earning potential. Inter-generational conflict underpinned the legislative scapegoating of Radio Caroline. This research demonstrates how financial controls can mask scapegoating and blame avoidance strategies by governments

Randomised, open-label, phase II study of Gemcitabine with and without IMM-101 for advanced pancreatic cancer

Background: Immune Modulation and Gemcitabine Evaluation-1, a randomised, open-label, phase II, first-line, proof of concept study (NCT01303172), explored safety and tolerability of IMM-101 (heat-killed Mycobacterium obuense; NCTC 13365) with gemcitabine (GEM) in advanced pancreatic ductal adenocarcinoma. Methods: Patients were randomised (2 : 1) to IMM-101 (10 mg ml−l intradermally)+GEM (1000 mg m−2 intravenously; n=75), or GEM alone (n=35). Safety was assessed on frequency and incidence of adverse events (AEs). Overall survival (OS), progression-free survival (PFS) and overall response rate (ORR) were collected. Results: IMM-101 was well tolerated with a similar rate of AE and serious adverse event reporting in both groups after allowance for exposure. Median OS in the intent-to-treat population was 6.7 months for IMM-101+GEM v 5.6 months for GEM; while not significant, the hazard ratio (HR) numerically favoured IMM-101+GEM (HR, 0.68 (95% CI, 0.44–1.04, P=0.074). In a pre-defined metastatic subgroup (84%), OS was significantly improved from 4.4 to 7.0 months in favour of IMM-101+GEM (HR, 0.54, 95% CI 0.33–0.87, P=0.01). Conclusions: IMM-101 with GEM was as safe and well tolerated as GEM alone, and there was a suggestion of a beneficial effect on survival in patients with metastatic disease. This warrants further evaluation in an adequately powered confirmatory study

Options for Producing a Warm-Water Fish in the UK: limits to "Green-Growth"?

This paper explores the development of a sustainable production system for tilapia and the research implications involved with ensuring commercial viability of such a system for UK farmers. The tilapia is a warm water fish with firm texture, white flesh and mild taste quite similar to a cod or haddock. Whilst tropical in origin it is thought to be highly suitable for low cost aquaculture in temperate zones with the potential to be a more sustainable source of food with fewer environmental impacts than other substitutes. Drawing on a literature review and findings from technical trials the paper will review and compare two production systems - novel Activated Suspension Technology (AST) and conventional Recirculating Aquaculture Systems (RAS) - considering their feasibility in terms of potential and financial viability for scaling up to commercial production of tilapia and their environmental and sustainability benefits. The review concludes that AST based only on microbial floc is currently uncompetitive with RAS in a UK context although the approach has benefits that might be incorporated in a new generation of mixed systems. Refinement of such systems needs to occur with potential adopters and could be part of diversification of mixed farms. Such development might further enhance the ethical values of fish produced in small-scale, modular RAS

Seafood in Food Security: A Call for Bridging the Terrestrial-Aquatic Divide

The contribution of seafood to global food security is being increasingly highlighted in policy. However, the extent to which such claims are supported in the current food security literature is unclear. This review assesses the extent to which seafood is represented in the recent food security literature, both individually and from a food systems perspective, in combination with terrestrially-based production systems. The results demonstrate that seafood remains under-researched compared to the role of terrestrial animal and plant production in food security. Furthermore, seafood and terrestrial production remain siloed, with very few papers addressing the combined contribution or relations between terrestrial and aquatic systems. We conclude that far more attention is needed to the specific and relative role of seafood in global food security and call for the integration of seafood in a wider interdisciplinary approach to global food system research
