  • Evidence-based practice has become a common expression in the helping professions over the last decade. Beginning with medicine and moving to fi elds such as psychology and social work, the number of books on evidencebased practice has grown signifi cantly. What makes this book different? This book is aimed at preservice and in-service school-based mental health service providers, such as school counselors, school psychologists, and school social workers. It is not a research book. It is a book about research-infused practice.

  • Data fusion is a research area that is growing rapidly due to the fact that it provides means for combining pieces of information coming from different sources/sensors, resulting in ameliorated overall system performance (improved decision making, increased detection capabilities, diminished number of false alarms, improved reliability in various situations at hand) with respect to separate sensors/sources.

  • With this new edition of Effective Expert Witnessing, Dr. Matson has added new information that is critical to expert witnessing in the late 1990s. In the decade since the first edition of this book was published, expert witnessing has been transformed by a series of court rulings generally concerned with the reliability, relevancy, and admissibility of expert testimony. Expert witnessing and trial strategy have not been the same since these decisions.

  • Sources of Evidence: Clinical Trials and Registries The notion of learning from observation of patients is as old as medicine itself. Over the last 50 years, our understanding of how best to turn raw observation into useful evidence has evolved considerably. Case reports, personal anecdotal experience, and small single-center case series are now recognized as having severe limitations to validity and have no role in formulating modern standards of practice. The major tools used to develop reliable evidence consist of the randomized clinical trial and the large observational registry.

  • Despite our best intentions, most of what constitutes modern medical imaging practice is based on habit, anecdotes, and scientific writings that are too often fraught with biases. Best estimates suggest that only around 30% of what constitutes “imaging knowledge” is substantiated by reliable scientific inquiry. This poses problems for clinicians and radiologists, because inevitably, much of what we do for patients ends up being inefficient, inefficacious, or occasionally even harmful.

  • A case study is a way to test the applicability of a theory using real-world evidence. The intent is not necessarily to select a successful or unsuccessful example, but rather to demonstrate that leadership is a key element in project management, and a project cannot succeed without it. The selected case is tested in this step, with the purpose of showing how leadership skills affect projects. The case study selected is Skanska, a major international construction company.

  • We use heterogeneity in the timing of television’s introduction to different local markets to identify the effect of preschool television exposure on standardized test scores during adolescence. Our preferred point estimate indicates that an additional year of preschool television exposure raises average adolescent test scores by about 0.02 standard deviations. We are able to reject negative effects larger than about 0.03 standard deviations per year of television exposure.

  • The additional material includes a new Background section, intended to provide a broad overview of breast cancer for non-clinicians; a new Topic 1, Primary care and the management of women at high risk; and a new Topic 8, Management of advanced, recurrent and metastatic disease. The topic areas and numbers therefore differ from the original Manual. Material in the Evidence sections of the topic areas is based on systematic reviews of research evidence carried out by the NHS Centre for Reviews and Dissemination.

  • Reliable gene-lifestyle interaction studies will yield important evidence for the shaping of personalised healthcare. Studies need statistical power with adequate environmental exposures and lifestyle heterogeneity to obtain reliable evidence on the interplay between nurture and nature. Europe has a historic strength in large epidemiological studies but technology development and implementation is needed to better ascertain environmental exposure and dietary heterogeneity.

  • Once you have your thin pieces roughed out, they need to be brought to their final thickness, and the obvious choice for this is to use a planer, if you have one, or visit your local cabinet shop and use their planer or wide belt sander. Or you can belt sand the pieces with a hand belt sander to approximate thickness, though this is not a reliable means of getting a consistent thickness. Using hand planes to thickness the stock gives you more control, as well as sore muscles, but all kidding aside if you have a penchant for planes...

  • In Lyme Borreliosis, western blot is the preferred serologic test. Antigen detection tests (antigen capture and PCR), although insensitive, are very specific and are especially helpful in evaluating the seronegative patient and those still ill or relapsing after therapy. Often, these antigen detection tests are the only positive markers of Bb infection, as seronegativity has been reported to occur in as many as 30% to 50% of cases. Nevertheless, active LB can be present even if all of these tests are non-reactive! Clinical diagnosis is therefore required.

  • Transport diversity is a general terminology used for selecting or preferring a network exit-point for end-user application traffic across network topologies that have a variety of characteristics. These characteristics include things like monetary cost, reliability or availability, availability of bandwidth, and latency. One example of transport diversity is a branch office environment that has a primary path using Frame Relay and a backup or alternate path using basic rate ISDN.

  • The use of individuals’ credit histories to predict the risk of future loss has become a common practice among automobile and homeowners insurers. The practice has proven to be controversial not only because of concerns about how reliably credit scores may predict risk. Many industry professionals, policymakers, and consumer groups have expressed concern that the practice may pose a significant barrier to economically vulnerable segments of the population in obtaining affordable automobile and homeowners coverage.

  • Providing convincing evidence on the effects of financial education is no easy task. The most straightforward but least reliable method is to ask people attending a seminar whether it was useful and whether participation will change their behaviour. There are three main problems. Attendance is self-selected. Those motivated to turn up may have the greatest interest in financial matters and may already be contemplating making a change in their finances.

This document therefore aims to define minimum standards for measuring and monitoring growth in children with CKD, based on local expert opinion, international committee reports, and indirectly supportive peer-reviewed clinical trials and reviews.

  • Our results suggest that nancial systems may exhibit a robust-yet-fragile tendency: while the probability of contagion may be low, the effects can be extremely widespread when problems occur. The model also highlights how seemingly indistinguishable shocks can have very different consequences for the nancial system depending on whether or not the shock hits at a particular pressure point in the network structure. This helps explain why the evidence of the resilience of the system to fairly large shocks prior to 2007 was not a reliable guide to its future robustness....
