Although there are many studies assessing the influence of religious beliefs on health they do not agree on whether the impact is positive or negative. More so, there is no consensus in the available literature on the definition of fatalism and what it means to individuals. In this phenomenological study we attempt to define what religious fatalism means to people living with diabetes in Khartoum, and how it affects their health beliefs, and how those beliefs affect their sense of coherence and generalized resistance resources, since salutogenesis is the guiding theory in this study...

Distributed vibration sensing based on phase-sensitive optical time domain reflectometry ( ϕ -OTDR) is being widely used in several applications. However, one of the main challenges in coherent detection-based ϕ -OTDR systems is the fading noise, which impacts the detection performance. In addition, typical signal averaging and differentiating techniques are not suitable for detecting high frequency events. This paper presents a new approach for reducing the effect of fading noise in fiber optic distributed acoustic vibration sensing systems without any impact on the frequency response of the detection system...

INTRODUCTION: Parent/caregivers' inability to recognize the importance of baby teeth has been associated with inadequate self-management of children's oral health (i.e. lower likelihood of preventive dental visits) which may result in dental caries and the need for more expensive caries-related restorative treatment under general anesthesia. Health behavior theories aid researchers in understanding the impact and effectiveness of interventions on changing health behaviors and health outcomes...

Spasers are a new class of laser devices with cavity sizes free from optical diffraction limit. They are an emergent tool for various applications, including biochemical sensing, superresolution imaging, and on-chip optical communication. According to its original definition, a spaser is a coherent surface plasmon amplifier that does not necessarily generate a radiative photon output. However, to date, spasers have only been studied with scattered photons, and their intrinsic surface plasmon emission is a "dark" emission that is yet to be revealed because of its evanescent nature...

BACKGROUND: Psoriasis is an inflammatory, long-term condition (LTC) involving co-morbidities, unhealthy lifestyle and significant life impact. Patients' understanding of psoriasis is limited and support lacking. The Common-Sense Self-Regulatory Model emphasises the role of illness/treatment beliefs on coping/self-management. New 'Pso Well(®) ' patient materials informed by the model addressed: psoriasis as a LTC; medications management; and lifestyle behaviours. OBJECTIVES: To investigate whether Pso Well(®) materials: 1) broaden understanding of psoriasis without increasing anxiety; 2) are acceptable and; 3) comprise features that appear to effect change...

Arik Bergman, Tomi Langer, Moshe Tur
A novel technique combining Brillouin phase-shift measurements with Brillouin dynamic gratings (BDGs) reflectometry in polarization-maintaining fibers is presented here for the first time. While a direct measurement of the optical phase in standard BDG setups is impractical due to non-local phase contributions, their detrimental effect is reduced by ~4 orders of magnitude through the coherent addition of Stokes and anti-Stokes reflections from two counter-propagating BDGs in the fiber. The technique advantageously combines the high-spatial-resolution of BDGs reflectometry with the increased tolerance to optical power fluctuations of phasorial measurements, to enhance the performance of fiber-optic strain sensors...

BACKGROUND: Resilience is the ability to overcome any stressful situation. The ability to bounce back is said to enable a person to emerge stronger, perform better, and become more confident and selfefficient. The new graduate nurses' journey is a stressful experience as they become immersed in the day-to-day work pressures. OBJECTIVE: The study explored the new graduate nurses' accounts of resilience and the facilitating and impeding factors in building their resilience...

The current debate over extending inheritance and its evolutionary impact has focused on adding new categories of non-genetic factors to the classical transmission of DNA, and on trying to redefine inheritance. Transmitted factors have been mainly characterized by their directions of transmission (vertical, horizontal, or both) and the way they store variations. In this paper, we leave aside the issue of defining inheritance. We rather try to build an evolutionary conceptual framework that allows for tracing most, if not all forms of transmission and makes sense of their different tempos and modes...

Matched field processing is a generalized beamforming method that matches received array data to a dictionary of replica vectors in order to locate one or more sources. Its solution set is sparse since there are considerably fewer sources than replicas. Using compressive sensing (CS) implemented using basis pursuit, the matched field problem is reformulated as an underdetermined, convex optimization problem. CS estimates the unknown source amplitudes using the replica dictionary to best explain the data, subject to a row-sparsity constraint...

REVIEW
Sarah Wood Pallas, Jennifer Prah Ruger
Development aid for health increased dramatically during the past two decades, raising concerns about inefficiency and lack of coherence among the growing number of global health donors. However, we lack a framework for how donor proliferation affects health program performance to inform theory-based evaluation of aid effectiveness policies. A review of academic and gray literature was conducted. Data were extracted from the literature sample on study design and evidence for hypothesized effects of donor proliferation on health program performance, which were iteratively grouped into categories and mapped into a new conceptual framework...

There is a lack of systematic evidence concerning health orientation in maternity practice in the current climate of risk avoidance. The midwifery professional project is orientated toward the preservation of normal physiological processes during the maternity episode. This study investigates accounts of midwives who were working in health-orientated birth settings, to examine if and how they frame a health orientation in professional practice. Twenty-seven narrative interviews were conducted with midwives working in pre-, peri-, and postnatal care in different maternity care settings in Switzerland, Austria, and Germany...

BACKGROUND: All health workers should take responsibility for infection prevention and control (IPC). Recent reduction in key reported healthcare-associated infections in the UK is impressive, but the determinants of success are unknown. It is imperative to understand how IPC strategies operate as new challenges arise and threats of antimicrobial resistance increase. METHODS: The authors undertook a retrospective, independent evaluation of an action plan to enhance IPC and 'ownership' (individual accountability) for IPC introduced throughout a healthcare organization...

In the current article, we review existing models of the etiology of voice hearing. We summarize the argument and evidence that voice hearing is primarily a dissociative process involving critical aspects of self. We propose a complementary perspective on these phenomena that is based on a modern behavioral account of complex behavior known as relational frame theory. This type of approach to voice hearing concerns itself with the functions served for the individual by this voice hearing; the necessary history, such as trauma, that establishes these functions; and the relevant dissociative processes involving self and others...

The capabilities of surface plasmon resonance (SPR) for characterization of colloidal particles were evaluated for 100, 300, and 460 nm nominal diameter polystyrene (PS) latexes. First the accuracy of measuring the effective refractive index (neff) of turbid colloids using SPR was quantified. It was concluded that for submicrometer sized PS particles the accuracy is limited by the reproducibility between replicate injections of samples. An SPR method was developed for obtaining the particle mean diameter (dpart) and the particle number concentration (cp) by fitting the measured neff of polystyrene (PS) colloids diluted in series with theoretical values calculated using the coherent scattering theory (CST)...

Life is so remarkable, and so unlike any other physical system, that it is tempting to attribute special factors to it. Physics is founded on the assumption that universal laws and principles underlie all natural phenomena, but is it far from clear that there are 'laws of life' with serious descriptive or predictive power analogous to the laws of physics. Nor is there (yet) a 'theoretical biology' in the same sense as theoretical physics. Part of the obstacle in developing a universal theory of biological organization concerns the daunting complexity of living organisms...

CONTEXT: Observational research is increasingly being used in health professions education (HPE) research, yet it is often criticised for being prone to observer effects (also known as the Hawthorne Effect), defined as a research participant's altered behaviour in response to being observed. This article explores this concern. METHODS: First, this article briefly reviews the initial Hawthorne studies and the original formulation of the Hawthorne Effect, before turning to contemporary studies of the Hawthorne Effect in HPE and beyond...

Sense of coherence (SOC) and mindfulness (MI) are believed to promote the health and well-being of individuals and organisations. The aim of this longitudinal study was to contribute to the literature on the development of SOC through training and interventions and thereby explore the development of these constructs in a group of senior professionals in the German Catholic Church. A sample of eight participants voluntarily enrolled for a 12-day training programme spread over a period of nine months to develop intercultural and inter-religious competencies, SOC and MI...

Recently, lens-free imaging has evolved as an alternative imaging technology. The key advantages of this technology, including simplicity, compactness, low cost, and flexibility of integration with other components, have facilitated the realization of many innovative applications, especially, in the fields of the on-chip lens-free imaging and sensing. In this review, we discuss the development of lens-free imaging, from theory to applications. This article includes the working principle of lens-free digital inline holography (DIH) with coherent and semi coherent light, on-chip lens-free fluorescence imaging and sensing, lens-free on-chip tomography, lens-free on-chip gigapixel nanoscopy, detection of nanoparticles using on-chip microscopy, wide field microscopy, and lens-free shadow image based point-of-care systems...

Cross-frequency coherence of acoustic signals in a turbulent atmosphere is an important consideration for source localization with acoustic sensor arrays and for remote sensing of the atmosphere with sodars and tomography techniques. This paper takes as a starting point recently derived, closed-form equations for the spatial-temporal correlation function of a broadband acoustic signal propagating in a turbulent atmosphere with coupled spatial-temporal fluctuations in temperature and wind velocity. This theory is employed to calculate, based on the Rytov approximation, the two-point, two-time, two-frequency mutual coherence function of plane and spherical waves in the weak scattering regime...
