What works in intelligence

This report analyses police intelligence practice in Britain through the lens of the ‘what works?’ concept. It is based on a survey of a self-selected group of intelligence staff together with interviews with a random sample of their number. Participants reflected on: their skills and abilities; their training; their successes and their failures; and the utility of the structures and processes within which they operated. We found that respondents broadly agreed on what contributed to effective practice. For example, analysts, intelligence officers and managers ranked a skilled workforce as of greatest import. Human intelligence (HUMINT); operational teams, capable of responding quickly to intelligence; information technology; and plentiful sources of intelligence in their communities, were consistently ranked the top four significant factors in their successes. At the same time, we conclude that while the ‘what works?’ approach has some value when applied to policing, there are clear limits to its explanatory power. We conclude that the ‘what works?’ approach also raises important, albeit largely ignored, questions about institutional memory and identity and that institutional and cultural factors represent significant barriers to the adoption of evidence-based practice in policing

The road not taken: understanding barriers to the development of police intelligence practice

To better understand police intelligence practice, we examined practitioners’ views of their work and their relations with the wider law enforcement community. We surveyed intelligence staff (n = 110) and interviewed a random sample of respondents (n = 12). Our analysis suggested that traditionalism and the dominant action-oriented culture limit the organization’s understanding of intelligence practice. Largely, the focus in that context has been on street cops’ propensity to reject reflection in favor of action, but intelligence practitioners need also look to themselves. Too often, the philosophy of “need to know” is prioritized over its antithesis, “dare to share.” Though perceived by practitioners as low-risk and consistent with organizational norms, we argue that inappropriately applied “need to know” is the enemy of efficiency and real accountability, offering low levels of reward and discouraging the kinds of partnership, reciprocity, and multi-directional knowledge transfer that policing needs to be successful in the information age. We reconceptualized an interactivity/isolationism continuum, used in the natural sciences, to help interpret that phenomenon. We argue that isolationism is but one factor in a complex organizational dynamic, but it is a significant one because it can subtly limit the influence and reach of the intelligence milieu in previously unacknowledged ways

Genetic Regulation of Platelet Receptor Expression and Function: Application in Clinical Practice and Drug Development

Understanding genetic contributions to platelet function could have profound clinical ramifications for personalizing platelet-directed pharmacotherapy, by providing insight into the risks and possible benefits associated with specific genotypes. This article represents an integrated summary of presentations related to genetic regulation of platelet receptor expression and function given at the Fifth Annual Platelet Colloquium in January 2010. It is supplemented with additional highlights from the literature covering 1) approaches to determining and evidence for the associations of genetic variants with platelet hypo- and hyperresponsive phenotypes, 2) the ramifications of these polymorphisms with regard to clinical responses to antiplatelet therapies, and 3) the role of platelet function/genetic testing in guiding antiplatelet therapy

Searching biomedical databases on complementary medicine: the use of controlled vocabulary among authors, indexers and investigators

BACKGROUND: The optimal retrieval of a literature search in biomedicine depends on the appropriate use of Medical Subject Headings (MeSH), descriptors and keywords among authors and indexers. We hypothesized that authors, investigators and indexers in four biomedical databases are not consistent in their use of terminology in Complementary and Alternative Medicine (CAM). METHODS: Based on a research question addressing the validity of spinal palpation for the diagnosis of neuromuscular dysfunction, we developed four search concepts with their respective controlled vocabulary and key terms. We calculated the frequency of MeSH, descriptors, and keywords used by authors in titles and abstracts in comparison to standard practices in semantic and analytic indexing in MEDLINE, MANTIS, CINAHL, and Web of Science. RESULTS: Multiple searches resulted in the final selection of 38 relevant studies that were indexed at least in one of the four selected databases. Of the four search concepts, validity showed the greatest inconsistency in terminology among authors, indexers and investigators. The use of spinal terms showed the greatest consistency. Of the 22 neuromuscular dysfunction terms provided by the investigators, 11 were not contained in the controlled vocabulary and six were never used by authors or indexers. Most authors did not seem familiar with the controlled vocabulary for validity in the area of neuromuscular dysfunction. Recently, standard glossaries have been developed to assist in the research development of manual medicine. CONCLUSIONS: Searching biomedical databases for CAM is challenging due to inconsistent use of controlled vocabulary and indexing procedures in different databases. A standard terminology should be used by investigators in conducting their search strategies and authors when writing titles, abstracts and submitting keywords for publications

IQGAP1 Is Involved in Post-Ischemic Neovascularization by Regulating Angiogenesis and Macrophage Infiltration

Neovascularization is an important repair mechanism in response to ischemic injury and is dependent on inflammation, angiogenesis and reactive oxygen species (ROS). IQGAP1, an actin-binding scaffold protein, is a key regulator for actin cytoskeleton and motility. We previously demonstrated that IQGAP1 mediates vascular endothelial growth factor (VEGF)-induced ROS production and migration of cultured endothelial cells (ECs); however, its role in post-ischemic neovascularization is unknown.Ischemia was induced by left femoral artery ligation, which resulted in increased IQGAP1 expression in Mac3(+) macrophages and CD31(+) capillary-like ECs in ischemic legs. Mice lacking IQGAP1 exhibited a significant reduction in the post-ischemic neovascularization as evaluated by laser Doppler blood flow, capillary density and α-actin positive arterioles. Furthermore, IQGAP1(-/-) mice showed a decrease in macrophage infiltration and ROS production in ischemic muscles, leading to impaired muscle regeneration and increased necrosis and fibrosis. The numbers of bone marrow (BM)-derived cells in the peripheral blood were not affected in these knockout mice. BM transplantation revealed that IQGAP1 expressed in both BM-derived cells and tissue resident cells, such as ECs, is required for post-ischemic neovascularization. Moreover, thioglycollate-induced peritoneal macrophage recruitment and ROS production were inhibited in IQGAP1(-/-) mice. In vitro, IQGAP1(-/-) BM-derived macrophages showed inhibition of migration and adhesion capacity, which may explain the defective macrophage recruitment into the ischemic tissue in IQGAP1(-/-) mice.IQGAP1 plays a key role in post-ischemic neovascularization by regulating, not only, ECs-mediated angiogenesis but also macrophage infiltration as well as ROS production. Thus, IQGAP1 is a potential therapeutic target for inflammation- and angiogenesis-dependent ischemic cardiovascular diseases

Proteomic approaches to dissect platelet function: half the story

Platelets play critical roles in diverse hemostatic and pathologic disorders and are broadly implicated in various biological processes that include inflammation, wound healing, and thrombosis. Recent progress in high-throughput mRNA and protein profiling techniques has advanced our understanding of the biological functions of platelets. Platelet proteomics has been adopted to decode the complex processes that underlie platelet function by identifying novel platelet-expressed proteins, dissecting mechanisms of signal or metabolic pathways, and analyzing functional changes of the platelet proteome in normal and pathologic states. The integration of transcriptomics and proteomics, coupled with progress in bioinformatics, provides novel tools for dissecting platelet biology. In this review, we focus on current advances in platelet proteomic studies, with emphasis on the importance of parallel transcriptomic studies to optimally dissect platelet function. Applications of these global profiling approaches to investigate platelet genetic diseases and platelet-related disorders are also addressed
