Many statistical and methodological developments regarding fractal analyses have appeared in the scientific literature since the publication of the seminal texts introducing Fractal Physiology. However, the lion’s share of more recent work is distributed across many outlets and disciplines, including aquatic sciences, biology, computer science, ecology, economics, geology, mathematics, medicine, neuroscience, physics, physiology, psychology, and others. The purpose of this special topic is to solicit submissions regarding fractal and nonlinear statistical techniques from experts that span a wide range of disciplines. The articles will aggregate extensive cross-discipline expertise into comprehensive and broadly applicable resources that will support the application of fractal methods to physiology and related disciplines. The articles will be organized with respect to a continuum defined by the characteristics of the empirical measurements a given analysis is intended to confront. At one end of the continuum are stochastic techniques directed at assessing scale invariant but stochastic data. The next step in the continuum concerns self-affine random fractals and methods directed at systems that entail scale-invariant or 1/f patterns or related patterns of temporal and spatial fluctuation. Analyses directed at (noisy) deterministic signals correspond to the final stage of the continuum that relates the statistical treatments of nonlinear stochastic and deterministic signals. Each section will contain introductory articles, advanced articles, and application articles so readers with any level of expertise with fractal methods will find the special topic accessible and useful. Example stochastic methods include probability density estimation for the inverse power-law, the lognormal, and related distributions. Articles describing statistical issues and tools for discriminating different classes of distributions will be included. An example issue is distinguishing power-law distributions from exponential distributions. Modeling issues and problems regarding statistical mimicking will be addressed as well. The random fractal section will present introductions to several one-dimensional monofractal time-series analysis. Introductory articles will be accompanied by advanced articles that will supply comprehensive treatments of all the key fractal time series methods such as dispersion analysis, detrended fluctuation analysis, power spectral density analysis, and wavelet techniques. Box counting and related techniques will be introduced and described for spatial analyses of two and three dimensional domains as well. Tutorial articles on the execution and interpretation of multifractal analyses will be solicited. There are several standard wavelet based and detrended fluctuation based methods for estimating a multifractal spectrum. We hope to include articles that contrast the different methods and compare their statistical performance as well. The deterministic methods section will include articles that present methods of phase space reconstruction, recurrence analysis, and cross-recurrence analysis. Recurrence methods are widely applicable, but motivated by signals that contain deterministic patterns. Nonetheless recent developments such as the analysis of recurrence interval scaling relations suggest applicability to fractal systems. Several related statistical procedures will be included in this section. Examples include average mutual information statistics and false nearest neighbor analyses.

The brief, practical texts in the Essentials of Qualitative Methods series introduce social science and psychology researchers to key approaches to to qualitative methods, offering exciting opportunities to gather in-depth qualitative data and to develop rich and useful findings. Essentials of Interpretative Phenomenological Analysis is a step-by-step guide to a research method that investigates how people make sense of their lived experience in the context of their personal and social worlds. It is especially well-suited to exploring experiences perceived as highly significant, such as major life and relationship changes, health challenges, and other emotion-laden events. IPA studies highlight convergence and divergence across participants, showing both the experiential themes that the participants share and the unique way each theme is manifested for the individual. About the Essentials of Qualitative Methods book series: Even for experienced researchers, selecting and correctly applying the right method can be challenging. In this groundbreaking series, leading experts in qualitative methods provide clear, crisp, and comprehensive descriptions of their approach, including its methodological integrity, and its benefits and limitations. Each book includes numerous examples to enable readers to quickly and thoroughly grasp how to leverage these valuable methods.

This is the first report to look across the OECD membership at how regulatory impact analysis is actually designed and carried out.

Covers research in the area of systems analysis and design practices and methodologies.

Epidemiological information on influenza comes from multiple sources. Participatory surveillance for influenza and influenza-like illness (ILI) is one approach for gathering information from the community to monitor trends in influenza, while also helping to inform other important public health issues. The approach should be considered to be complementary to other sources of influenza surveillance information. One advantage of participatory surveillance is that information comes from both asymptomatic and symptomatic individuals, and from symptomatic individuals who may not initially seek health care. Information may also come from members of the population who may be underrepresented in traditional facility-based surveillance. Where participatory surveillance for influenza and ILI has been implemented experience indicates that such systems are accurate, flexible, cost-effective and robust with regard to changes in health care seeking behaviour. However, there are also a number of limitations, challenges and biases that must be taken into consideration. This WHO document provides globally applicable guidance on implementing participatory surveillance for influenza and ILI based on expert input and abundant experience from countries in which such surveillance has been implemented. The document sets out best practices for public health officials to consider, either when looking to implement a participatory surveillance system or when making changes to an existing system.
