Enhancing healthcare information sharing with blockchain technology

Blockchain, the foundation of many cryptocurrencies, also can be useful for many other industries such as healthcare. Blockchain can enforce immutability and non-repudiation for information stored on it. Although some say the technology is not yet mature enough, others are putting blockchain to the test with programs and pilots. Examining these efforts and dissecting the detail allows us to look at blockchain’s qualities and pitfalls to allow data sharing efforts with medical records.It is widely agreed that sharing medical data outside of the silos where it is captured or created will benefit the individual’s care and outcomes. Regulation and personal humility often stand in the way of this sharing. Blockchain is offering new and novel ways to share data properly and securely with only the providers or researchers who are supposed to receive it. Blockchain is also allowing the patient to take control of their health data and in some cases, even profit from it. This is the concept behind a proposal by the author to allow a patient to share all or part of their data for research and to be justly compensated for that sharing

Relationships among muscle dysmorphia characteristics, body image quality of life, and coping in males

Objectives: The purpose of this study was to examine relationships among bodybuilding dependence, muscle satisfaction, body image-related quality of life and body image-related coping strategies, and test the hypothesis that muscle dysmorphia characteristics may predict quality of life via coping strategies. Design: Participants (294 males, Mage=20.5 years, SD=3.1) participated in a cross-sectional survey. Methods: Participants completed questionnaires assessing muscle satisfaction, bodybuilding dependence, body image-related quality of life and body image-related coping. Results: Quality of life was correlated positively with muscle satisfaction and bodybuilding dependence but negatively with body image coping ( P< 0.05). Body image coping was correlated positively with bodybuilding dependence and negatively with muscle satisfaction ( P< 0.05). Mediation analysis found that bodybuilding dependence and muscle satisfaction predicted quality of life both directly and indirectly via body image coping strategies (as evidenced by the bias corrected and accelerated bootstrapped confidence intervals). Conclusions: These results provide preliminary evidence regarding the ways that muscularity concerns might influence body image-related quality of life

Learning Experiences Contributing to Service-Delivery Competence in Applied Psychologists: Lessons for Sport Psychologists

The purpose of the present study was to compare learning experiences perceived to contribute to service-delivery competence in sport, clinical, and counseling psychologists. Twenty psychologists (11 female, 9 male; 28–70 years of age) participated in semistructured interviews. All participants emphasized the role of client interactions in learning service-delivery processes. In addition, clinical and counseling participants reported personal therapy and supervision as influential experiences. Applied implications for training include (a) regional supervision networks comprising peers and elders, (b) university-based sport psychology clinics, and (c) personal and professional development groups

Towards using NMR to screen for spoiled tomatoes stored in 1,000 L, aseptically sealed, metal-lined totes.

Nuclear magnetic resonance (NMR) spectroscopy is used to track factory relevant tomato paste spoilage. It was found that spoilage in tomato paste test samples leads to longer spin lattice relaxation times T1 using a conventional low magnetic field NMR system. The increase in T1 value for contaminated samples over a five day room temperature exposure period prompted the work to be extended to the study of industry standard, 1,000 L, non-ferrous, metal-lined totes. NMR signals and T1 values were recovered from a large format container with a single-sided NMR sensor. The results of this work suggest that a handheld NMR device can be used to study tomato paste spoilage in factory process environments

Marginally Stable Nuclear Burning

Thermonuclear X-ray bursts result from unstable nuclear burning of the material accreted on neutron stars in some low mass X-ray binaries (LMXBs). Theory predicts that close to the boundary of stability oscillatory burning can occur. This marginally stable regime has so far been identified in only a small number of sources. We present Rossi X-ray Timing Explorer (RXTE) observations of the bursting, high- inclination LMXB 4U 1323-619 that reveal for the first time in this source the signature of marginally stable burning. The source was observed during two successive RXTE orbits for approximately 5 ksec beginning at 10:14:01 UTC on March 28, 2011. Significant mHz quasi- periodic oscillations (QPO) at a frequency of 8.1 mHz are detected for approximately 1600 s from the beginning of the observation until the occurrence of a thermonuclear X-ray burst at 10:42:22 UTC. The mHz oscillations are not detected following the X-ray burst. The average fractional rms amplitude of the mHz QPOs is 6.4% (3 - 20 keV), and the amplitude increases to about 8% below 10 keV.This phenomenology is strikingly similar to that seen in the LMXB 4U 1636-53. Indeed, the frequency of the mHz QPOs in 4U 1323-619 prior to the X-ray burst is very similar to the transition frequency between mHz QPO and bursts found in 4U 1636-53 by Altamirano et al. (2008). These results strongly suggest that the observed QPOs in 4U 1323-619 are, like those in 4U 1636-53, due to marginally stable nuclear burning. We also explore the dependence of the energy spectrum on the oscillation phase, and we place the present observations within the context of the spectral evolution of the accretion-powered flux from the source

Einstein--Maxwell--Dilaton metrics from three--dimensional Einstein--Weyl structures

A class of time dependent solutions to $(3+1)$ Einstein--Maxwell-dilaton theory with attractive electric force is found from Einstein--Weyl structures in (2+1) dimensions corresponding to dispersionless Kadomtsev--Petviashvili and $SU(\infty)$ Toda equations. These solutions are obtained from time--like Kaluza--Klein reductions of $(3+2)$ solitons.Comment: 12 pages, to be published in Class.Quantum Gra

Conducting a systematic review: Demystification for trainees in sport and exercise psychology

The purpose of this article is to define and detail the steps in conducting systematic reviews for trainees and supervisors. We also offer suggestions garnered from our experiences reading, conducting, publishing, and reviewing such manuscripts. Steps include: developing specific questions and inclusion/exclusion criteria; undertaking a multi-strategy literature search; implementing replicable data extraction methods; assessing study quality; and employing transparent procedures for synthesising and presenting results. Suggestions include: developing a proposal and having it reviewed, allowing sufficient time to conduct a review, keeping meticulous records, and adhering to established procedures

Energy distribution of charged dilaton black holes

Chamorro and Virbhadra studied, using the energy-momentum complex of Einstein, the energy distribution associated with static spherically symmetric charged dilaton black holes for an arbitrary value of the coupling parameter $\gamma$ which controls the strength of the dilaton to the Maxwell field. We study the same in Tolman's prescription and get the same result as obtained by Chamorro and Virbhadra. The energy distribution of charged dilaton black holes depends on the value of $\gamma$ and the total energy is independent of this parameter.Comment: 8 pages, RevTex, no figure
