'Like a prison without bars' : dementia and experiences of dignity
2013
Author's version of an article in the journal: Nursing Ethics. Also available from the publisher at: http://dx.doi.org/10.1177/0969733013484484 The aim of this article is to investigate how life in Norwegian nursing homes may affect experiences of dignity among persons with dementia. The study had a qualitative design and used a phenomenological and hermeneutic approach. Participant observation in two nursing home units was combined with qualitative interviews with five residents living in these units. The study took place between March and December 2010. The residents feel that their freedom is restricted, and they describe feelings of homesickness. They also experience that they are not b…
A heuristic model-based approach for compensating wind effects in ski jumping.
2021
Wind influences the jump length in ski jumping, which raises questions about the fairness. To counteract the wind problem, the International Ski Federation has introduced a wind compensation system in 2009: time-averaged wind velocity components tangential to the landing slope are obtained from several sites along the landing slope, and these data are used in a linear statistical model for estimating the jump length effect of wind. This is considered in the total score of the ski jump. However, it has been shown that the jump length effect estimates can be inaccurate and misleading. The present manuscript introduces an alternative mathematical wind compensation approach that is based on an …
Searching for pulsed emission from XTE J0929-314 at high radio frequencies
2009
The aim of this work is to search for radio signals in the quiescent phase of accreting millisecond X-ray pulsars, in this way giving an ultimate proof of the recycling model, thereby unambiguously establishing that accreting millisecond X-ray pulsars are the progenitors of radio millisecond pulsars. To overcome the possible free-free absorption caused by matter surrounding accreting millisecond X-ray pulsars in their quiescence phase, we performed the observations at high frequencies. Making use of particularly precise orbital and spin parameters obtained from X-ray observations, we carried out a deep search for radio-pulsed emission from the accreting millisecond X-ray pulsar XTE J0929-31…
Constant-roll inflation: confrontation with recent observational data
2017
The previously proposed class of phenomenological inflationary models in which the assumption of inflaton slow-roll is replaced by the more general, constant-roll condition is compared with the most recent cosmological observational data, mainly the Planck ones. Models in this two-parametric class which remain viable appear to be close to the slow-roll ones, and their inflaton potentials are close to (but still different from) that of the natural inflation model. Permitted regions for the two model parameters are presented.
The Gravity Lagrangian According to Solar System Experiments
2005
In this work we show that the gravity lagrangian f(R) at relatively low curvatures in both metric and Palatini formalisms is a bounded function that can only depart from the linearity within the limits defined by well known functions. We obtain those functions by analysing a set of inequalities that any f(R) theory must satisfy in order to be compatible with laboratory and solar system observational constraints. This result implies that the recently suggested f(R) gravity theories with nonlinear terms that dominate at low curvatures are incompatible with observations and, therefore, cannot represent a valid mechanism to justify the cosmic speed-up.
Astrophysik contra Astronomie
1981
[Astrophysics contra astronomy] means the displacement of astrometry and stellar astronomy as the main and solely conceded branches of astronomy by the new astrophysics. This displacement started with the introduction of spectroscopic and photometric methods of observation in astronomy founded by J. C. F. Zoellner and W. Huggins in the late 1850s. It was Zoellner, too, who gave the methodical and intrumental foundations of the new branch called consciously [Astrophysik] by him, because it gives insight into the [physical constitution] of the celestial bodies - whereas the traditional astronomy (or: astrophysics according to the older meaning) had been studying only the motions of the stars …
Editorial Judgments
2009
Based on participant observation of editors’ decisions for a sociology journal, the paper investigates the peer review process. It shows a hidden interactivity in peer review, which is overlooked both by authors who impute social causes to unwelcome decisions, and by the preoccupation with ‘reliability’ prevalent in peer review research. This study shows that editorial judgments are: (1) attitudes taken by editorial readers toward various kinds of text, as a result of their membership in an intellectual milieu; (2) impressions gained through the reading process (through a ‘virtual interaction’ with the author); and (3) rationalizing statements about manuscripts made by editors and addressed…
Optimal calculation steps for the evaluation of residual stress by the incremental hole-drilling method
1999
The integral method is a suitable calculation procedure for the determination of nonuniform residual stresses by semidestructive mechanical methods such as the hole-drilling method and the ring-core method. However, the high sensitivity to strain measurement errors due to the ill conditioning of the equations has hindered its practical use. the analysis of the influence of the strain measurment error on the computed stresses carried out in the present work has showed that, given both maximum hole depth and number of total steps, the error sensitivity depends on the particular depth increment distribution used. By means of the matrix formulation, the depth increment distribution that optimiz…
Observational Study of Antibiotic Usage at the Children’s Clinical University Hospital in Riga, Latvia
2018
Background and objectives: Many pediatric patients have been treated with antibiotics during their hospitalization. There is a need to improve antibiotic prescribing for pediatric patients because many of these prescriptions are inappropriate. Antibiotic consumption analysis was conducted at the Children&rsquo
Avoiding Bias in Observational Studies
2009
Background Many questions in human health research can only be answered with observational studies. In contrast to controlled experiments or well-planned, experimental randomized clinical trials, observational studies are subject to a number of potential problems that may bias their results.
