Textbook descriptions of people with psychosis – some ethical aspects
2018
Background:Textbooks are central for the education of professionals in the health field and a resource for practitioners already in the field.Objectives:This article focuses on how 12 textbooks in psychiatric nursing and psychiatry, published in Norway between 1877 and 2012, describe and present people with psychosis.Research design:We used qualitative content analysis.Ethical considerations:The topic is published textbooks, made available to be read by students, teachers and professionals, and no ethical approval was required.Findings:The analysis shows that all 12 textbooks describe and present people who are considered as psychotic from a ‘perspective from above’. In this perspective, th…
Implementing Performance Reporting in Local Government: A Cross-Countries Comparison
2016
ABSTRACTProviding information on economy, efficiency, and effectiveness is one of the most important innovations in local government management, with performance reporting emerging as a new component for accountability and decision-making. This article compares 17 countries to ascertain whether there is convergence between them, studying key issues in the implementation of performance reporting by local governments. It also identifies some lessons that can be of use to countries that want to implement or improve performance reporting systems. Findings show that there is no convergence in practice or results, and that institutional factors influence the implementation of performance reportin…
“How Real People Really Need Mathematics in the Real World”—Authenticity in Mathematics Education
2018
This paper discusses authenticity from the perspective of mathematics education. Often, school mathematics offers students inauthentic word problems, which don’t show the authentic usefulness of mathematics in real life. In some tasks, authentic aspects are combined with inauthentic ones (e.g., an authentic context, but the question is artificial and different from what people within that context would ask). Several studies show that students are more motivated by authentic questions than by authentic contexts. Embedding these findings, I discuss issues associated with defining authenticity in education. A first issue is that philosophers use the term to characterize a person’s existential …
Tropomyosin: A panallergen that causes a worldwide allergic problem
2021
Background: Panallergens are proteins that take part in key processes of organisms and, therefore, are ubiquitously distributed with highly conserved sequences and structures. One class of these panallergens is composed of the tropomyosins. The highly heat-stable tropomyosins comprise the major allergens in crustaceans and mollusks, which make them important food allergens in exposed populations. Tropomyosins are responsible for a widespread immunoglobulin E cross-reactivity among allergens from different sources. Allergic tropomyosins are expressed in many species, including parasites and insects. Methods: This panallergen class is divided, according to it capacity of induced allergic symp…
Cox ring of the generic fiber
2017
Abstract Given a surjective morphism π : X → Y of normal varieties satisfying some regularity hypotheses we prove how to recover a Cox ring of the generic fiber of π from the Cox ring of X. As a corollary we show that in some cases it is also possible to recover the Cox ring of a very general fiber, and finally we give an application in the case of the blowing-up of a toric fiber space.
Social Perceptions and Attitudes Towards Climate Change in Poland and in Turkey
2017
Climate change is perceived as a threat to future human well-being and a challenge to sustainable development of local communities and economies world-wide. While some countries and regions are expected to experience slight gains from the climatic changes the other are exposed to major losses. Ever more frequent natural disasters come as warning symptoms of the changes. However, for the sake of effective and efficient adaptation in various world regions answers to the following questions are important: do people notice this changes, do they experience their negative effects, are they satisfied with the climate change mitigation and adaptation actions taken by the governments, are they willi…
Determination of association constants towards carbon nanotubes† †Electronic supplementary information (ESI) available: Synthetic details and charact…

We describe a simple procedure for the determination of association constants between soluble molecules and insoluble and heterogeneous carbon nanotube samples.
Power-law hereditariness of hierarchical fractal bones
2013
SUMMARY In this paper, the authors introduce a hierarchic fractal model to describe bone hereditariness. Indeed, experimental data of stress relaxation or creep functions obtained by compressive/tensile tests have been proved to be fit by power law with real exponent 0 ⩽ β ⩽1. The rheological behavior of the material has therefore been obtained, using the Boltzmann–Volterra superposition principle, in terms of real order integrals and derivatives (fractional-order calculus). It is shown that the power laws describing creep/relaxation of bone tissue may be obtained by introducing a fractal description of bone cross-section, and the Hausdorff dimension of the fractal geometry is then related …
Analysis of oblique rebound using a redefinition of the coefficient of tangential restitution coefficient
2013
Abstract A redefinition of the coefficient of tangential restitution based on the separation of friction and restitution effects is presented. Using this modified coefficient of tangential restitution and the usual definitions of the coefficients of normal restitution and sliding friction, a description of oblique impacts in both stick and slip regimes is obtained. This, description, which is tested with available rebound data in literature, avoids sharp (apparent) variations in the coefficient tangential restitution with impact angle and can justify anomalous results reported by Calsamiglia et al. (1999) .

(A-C) Lymphocyte transformation test for dose optimisation of Ag85A, ESAT-6 and H37Rv by using PBMCs of healthy individuals (N = 10) and pulmonary TB (N = 10) patients using H3-thymidine uptake assay. PHA and PPD were used as positive control and wells with unstimulated cells were taken as control. Lymphoproliferative responses of healthy individuals and pulmaonary TB patients were calculated using different concentration (2.5, 5, 7.5, 10, 15, μg/ml) of antigens. Bar diagram showing mean ± SEM of stimulation indices (S.I) of stimulated PBMC’s with different doses of PHA, PPD, A85A, ESAT-6 and H37Rv. S.I was calculated according to the formula: S I = Mean counts per minute of experimental we…
