Three-part Series (three-part + series)
Selected AbstractsThinking Strategically About Women's Health A Dynamic Three-Part SeriesNURSING FOR WOMENS HEALTH, Issue 6 2001Jaynelle F. Stichler DNSc Editor's Note: In June 2000, Lifelines launched its first series on the business of women's health. As women's health continues to emerge as a "must-provide" services line for all types of health care organizations, Lifelines again asked widely recognized women's health services experts to revisit the notion of creating a women's health business model. Beginning in this issue, and continuing through the next two issues, we'll explore the strategies, marketing approaches and needed finance tools in developing a successful women's health business model. [source] Introduction to diffusion tensor imaging mathematics: Part III.CONCEPTS IN MAGNETIC RESONANCE, Issue 2 2006Tensor calculation, noise, optimization, simulations Abstract The mathematical aspects of diffusion tensor magnetic resonance imaging (DTMRI, or DTI), the measurement of the diffusion tensor by magnetic resonance imaging (MRI), are discussed in this three-part series. Part III begins with a comparison of different ways to calculate the tensor from diffusion-weighted imaging data. Next, the effects of noise on signal intensities and diffusion tensor measurements are discussed. In MRI signal intensities as well as DTI parameters, noise can introduce a bias (systematic deviation) as well as scatter (random deviation) in the data. Propagation-of-error formulas are explained with examples. Step-by-step procedures for simulating diffusion tensor measurements are presented. Finally, methods for selecting the optimal b factor and number of b = 0 images for measuring several properties of the diffusion tensor, including the trace (or mean diffusivity) and anisotropy, are presented. © 2006 Wiley Periodicals, Inc. Concepts Magn Reson Part A 28A: 155,179, 2006 [source] Coining and Defining Novel Nursing Terminology.INTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 1 2009Part 3: Critical Incident Control PURPOSE.,In the third of a three-part series, a novel nursing terminology is introduced and proposed for inclusion in the Nursing Outcomes Classification (NOC),Critical incident control (CIC),defined as a response that attempts to reverse a life-threatening condition. Critical incident nursing diagnosis (CIND), defined as recognition of an acute life-threatening event that occurs as a result of disease, surgery, treatment, or medication, and critical incident nursing intervention, defined as any indirect or direct care registered nurse,initiated treatment, based upon clinical judgment and knowledge that a registered nurse performs in response to a CIND, were introduced in Parts 1 and 2 of this series, respectively. DATA SOURCES.,The current literature, research studies, meta-analyses from a variety of disciplines, and personal clinical experience serve as the data sources for this article. DATA SYNTHESIS.,The current nursing outcomes in the NOC are inaccurate or inadequate for describing nursing care during life-threatening situations. The lack of standardized nursing terminology creates a barrier that may impede critical communication and patient care during life-threatening situations. CONCLUSION.,Coining and defining novel nursing terminology, CIC, for patient care during life-threatening situations is important and fills the gap in the current standardized nursing terminology. IMPLICATIONS FOR NURSING PRACTICE.,Refining the NOC will permit nursing researchers, among others, to conduct studies on nursing diagnoses in conjunction with the proposed novel nursing terminology, CIC.

[source] Managing Congenitally Missing Lateral Incisors.JOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 4 2005Part III: Single-Tooth Implants ABSTRACT Three treatment options exist for the replacement of congenitally missing lateral incisors. They include canine substitution, a tooth-supported restoration, and a single-tooth implant. Selecting the appropriate treatment option depends on the malocclusion, anterior relationship, specific space requirements, and condition of the adjacent teeth. The ideal treatment is the most conservative option that satisfies individual esthetic and functional requirements. Today, the single-tooth implant has become one of the most common treatment alternatives for the replacement of missing teeth. This article closely examines the many interdisciplinary issues that arise when treatment planning the placement of single-tooth implants in patients with congenitally missing lateral incisors. The specific criteria that must be evaluated illustrate the importance of an interdisciplinary treatment approach to achieve optimal esthetics and long-term predictability. This is the final article of a three-part series discussing the three treatment alternatives for replacing congenitally missing lateral incisors. [source] Managing Congenitally Missing Lateral Incisors.JOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 1 2005Part I: Canine Substitution ABSTRACT Dentists often encounter patients with missing or malformed teeth. The maxillary lateral incisor is the second most common congenitally absent tooth. There are three treatment options that exist for replacing missing lateral incisors. They include canine substitution, a tooth-supported restoration, or a single-tooth implant. Selecting the appropriate option depends on the mal-occlusion, specific space requirements, tooth-size relationship, and size and shape of the canine. The ideal treatment is the most conservative option that satisfies individual esthetic and functional requirements. Often the ideal option is canine substitution. Although the orthodontist positions the canine in the most esthetic and functional location, the restorative dentist often needs to place a porcelain veneer or crown to re-create normal lateral incisor shape and color. This article closely examines patient selection and illustrates the importance of interdisciplinary treatment planning to achieve optimal esthetics. It is the first in a three-part series discussing the three treatment alternatives for replacing missing lateral incisors. [source] Grading quality of evidence and strength of recommendations in clinical practice guidelinesALLERGY, Issue 5 2009Part 1 of 3. The GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) approach provides guidance to grading the quality of underlying evidence and the strength of recommendations in health care. The GRADE system's conceptual underpinnings allow for a detailed stepwise process that defines what role the quality of the available evidence plays in the development of health care recommendations. The merit of GRADE is not that it eliminates judgments or disagreements about evidence and recommendations, but rather that it makes them transparent. This first article in a three-part series describes the GRADE framework in relation to grading the quality of evidence about interventions based on examples from the field of allergy and asthma. In the GRADE system, the quality of evidence reflects the extent to which a guideline panel's confidence in an estimate of the effect is adequate to support a particular recommendation. The system classifies quality of evidence as high, moderate, low, or very low according to factors that include the study methodology, consistency and precision of the results, and directness of the evidence. [source] Toward faster algorithms for dynamic traffic assignment.NETWORKS: AN INTERNATIONAL JOURNAL, Issue 1 2003Abstract Being first in a three-part series promising a practical solution to the user-equilibrium dynamic traffic assignment problem, this paper devises a parametric quickest-path tree algorithm, whose model makes three practical assumptions: (i) the traversal time of an arc i , j is a piecewise linear function of the arrival time at its i -node; (ii) the traversal time of a path is the sum of its arcs' traversal times; and (iii) the FIFO constraint holds, that is, later departure implies later arrival. The algorithm finds a quickest path, and its associated earliest arrival time, to every node for every desired departure time from the origin. Its parametric approach transforms a min-path tree for one departure-time interval into another for the next adjacent interval, whose shared boundary the algorithm determines on the fly. By building relatively few trees, it provides the topology explicitly and the arrival times implicitly of all min-path trees. Tests show the algorithm running upward of 10 times faster than the conventional brute-force approach, which explicitly builds a min-path tree for every departure time. Besides dynamic traffic assignment, other applications for which these findings have utility include traffic control planning, vehicle routing and scheduling, real-time highway route guidance, etc. © 2002 Wiley Periodicals, Inc. [source] Designing for performance, Part 1: Aligning your HPT decisions from top to bottomPERFORMANCE IMPROVEMENT, Issue 1 2007Ryan Watkins Wanting to improve individual and organizational performance is a worthwhile ambition. Yet your success in accomplishing this relies heavily on the suitable selection, design, and development of performance technologies. Only when capable performance technologies are systematically aligned with the desired results of your organization and its partners will you achieve sustainable performance improvements. In this article, the first of a three-part series, you will find a systematic process for initiating the design of a performance system that will accomplish useful results. From identifying the performance expectations of internal and external partners to justifying the performance objectives you establish as guides for future decision making, the systematic processes described in this article will provide you with the initial tools for successfully selecting an integrated set of performance technologies that have the capacity to accomplish valuable results. [source] Posttraumatic Stress Disorder Part III: Health Effects of Interpersonal Violence Among WomenPERSPECTIVES IN PSYCHIATRIC CARE, Issue 3 2006K. M. Hegadoren RN TOPIC.,The aim of this three-part series is to examine the sufficiency of the posttraumatic stress (PTSD) diagnostic construct to capture the full spectrum of human responses to psychological trauma. Part I (Lasiuk & Hegadoren, 2006a) reviewed the conceptual history of PTSD from the nineteenth century to its inclusion in the third edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1980), while Part II (Lasiuk & Hegadoren, 2006b) described subsequent refinements to the original PTSD diagnostic criteria and highlighted subsequent controversies. PURPOSE.,This paper focuses on interpersonal violence (sexual, physical, and emotional abuse/assault) and its sequelae in women. We argue in support of Judith Herman's (1992) conceptualization of the human trauma response as a spectrum, anchored at one end by an acute stress reaction that resolves on its own without treatment, and on the other by "complex" PTSD, with "classic" or "simple" PTSD somewhere between the two. SOURCES OF INFORMATION.,The existing theoretical, clinical and research literatures related to humans responses to trauma. CONCLUSION.,The paper concludes with a call for the need to increase a gendered perspective in all aspects of trauma research and clinical service delivery.

Part 1 of this series provides the application of key elements from the Food and Drug Administration Good Laboratory Practices and the current Good Manufacturing Practices regulations as the framework for the implementation of sound quality systems in a bioanalytical laboratory to be in compliance with current regulatory expectations. Copyright © 2007 John Wiley & Sons, Ltd. [source] Scaling turbulent atmospheric stratification.THE QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY, Issue 631 2008I: Turbulence, waves Abstract In this first of a three-part series, we argue that the dynamics of turbulence in a stratified atmosphere should depend on the buoyancy over a wide range of vertical scales and on energy flux over a wide range of horizontal scales; it should be scaling, but anisotropic, not isotropic. We compare the leading statistical theories of atmospheric stratification which are conveniently distinguished by the elliptical dimension Ds which quantifies their degree of spatial stratification. This includes the mainstream isotropic 2-D (large scales), isotropic 3-D (small scales) theory but also the more recent linear gravity wave theories (Ds = 7/3) and the classical fractionally integrated flux (FIF) 23/9-D unified scaling model. In the latter, the horizontal wind has a k,5/3 spectrum as a function of horizontal wavenumber determined by the energy flux and a k,11/5 energy spectrum as a function of vertical wavenumber determined by the buoyancy force variance flux. In this model, the physically important notion of scale is determined by the turbulent dynamics, it is not given a priori (i.e. the by usual Euclidean distance). The 23/9-D FIF model is the most physically and empirically satisfying, being based on turbulent (spectral) fluxes. The FIF model as originally proposed by Schertzer and Lovejoy is actually a vast family of scaling models broadly compatible with turbulent phenomenology and with the classical turbulent laws of Kolmogorov, Corrsin and Obukov. However, until now it has mostly been developed on the basis of structures localized in space,time. In this paper, we show how to construct extreme FIF models with wave-like structures which are localized in space but unlocalized in space,time, as well as a continuous family of intermediate models which are akin to Lumley,Shur models in which some part of the localized turbulent energy ,leaks' into unlocalized waves. The key point is that the FIF requires two propagators (space,time Green's functions) which can be somewhat different. The first determines the space,time structure of the cascade of fluxes; this must be localized in space,time in order to satisfy the usual turbulence phenomenology. In contrast, the second propagator relates the turbulent fluxes to the observables; although the spatial part of the propagator is localized as before, in space,time it can be unlocalized. (It is still localized in space, now in wave packets.) We display numerical simulations which demonstrate the requisite (anisotropic, multifractal) statistical properties as well as wave-like phenomenologies. In parts II and III we will examine the empirical evidence for the spatial and temporal parts, respectively, of the model using state-of-the-art lidar data of aerosol backscatter ratios (which we use as a surrogate for passive scalar concentration).
