'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…
DsixTools 2.0: The Effective Field Theory Toolkit
2021
$\tt DsixTools$ is a Mathematica package for the handling of the Standard Model Effective Field Theory (SMEFT) and the Low-energy Effective Field Theory (LEFT) with operators up to dimension six, both at the algebraic and numerical level. $\tt DsixTools$ contains a visually accessible and operationally convenient repository of all operators and parameters of the SMEFT and the LEFT. This repository also provides information concerning symmetry categories and number of degrees of freedom, and routines that allow to implement this information on global expressions (such as decay amplitudes and cross-sections). $\tt DsixTools$ also performs weak basis transformations, and implements the full on…
Geodesically complete BTZ-type solutions of $2+1$ Born-Infeld gravity
2016
We study Born-Infeld gravity coupled to a static, nonrotating electric field in $2+1$ dimensions and find exact analytical solutions. Two families of such solutions represent geodesically complete, and hence nonsingular, spacetimes. Another family represents a point-like charge with a singularity at the center. Despite the absence of rotation, these solutions resemble the charged, rotating BTZ solution of General Relativity but with a richer structure in terms of horizons. The nonsingular character of the first two families turn out to be attached to the emergence of a wormhole structure on their innermost region. This seems to be a generic prediction of extensions of General Relativity for…
Quantum nonlocality in extended theories of gravity
2020
We investigate how pure-state Einstein-Podolsky-Rosen correlations in the internal degrees of freedom of massive particles are affected by a curved spacetime background described by extended theories of gravity. We consider models for which the corrections to the Einstein-Hilbert action are quadratic in the curvature invariants and we focus on the weak-field limit. We quantify nonlocal quantum correlations by means of the violation of the Clauser-Horne-Shimony-Holt inequality, and show how a curved background suppresses the violation by a leading term due to general relativity and a further contribution due to the corrections to Einstein gravity. Our results can be generalized to massless p…
Infrared enhanced analytic coupling and chiral symmetry breaking in QCD
2005
We study the impact on chiral symmetry breaking of a recently developed model for the QCD analytic invariant charge. This charge contains no adjustable parameters, other than the QCD mass scale $\Lambda$, and embodies asymptotic freedom and infrared enhancement into a single expression. Its incorporation into the standard form of the quark gap equation gives rise to solutions for the dynamically generated mass that display a singular confining behaviour at the origin. Using the Pagels-Stokar method we relate the obtained solutions to the pion decay constant $f_{\pi}$, and estimate the scale parameter $\Lambda$, in the presence of four active quarks, to be about 880 MeV.
Space and Time Averaged Quantum Stress Tensor Fluctuations
2021
We extend previous work on the numerical diagonalization of quantum stress tensor operators in the Minkowski vacuum state, which considered operators averaged in a finite time interval, to operators averaged in a finite spacetime region. Since real experiments occur over finite volumes and durations, physically meaningful fluctuations may be obtained from stress tensor operators averaged by compactly supported sampling functions in space and time. The direct diagonalization, via a Bogoliubov transformation, gives the eigenvalues and the probabilities of measuring those eigenvalues in the vacuum state, from which the underlying probability distribution can be constructed. For the normal-orde…
An exploration of organization dissent and workplace freedom of speech among young professional intra-urban migrants in Shanghai
2017
This study explores the factors influencing the dissent behavior and perceptions of workplace freedom of speech among young Chinese professionals who are intra-urban migrants. It attempts to grasp the role of the Chinese household registration system, referred to as Hukou, in migrants’ professional and everyday life. Fourteen interviews were conducted with young, well-educated intra-urban migrants who possessed middle-income jobs but did not possess a Shanghai registration (Hukou). This study reveals that traditional Confucian values are significant in shaping Chinese migrant workers’ expressions of dissent and perceptions of workplace freedom of speech. Findings from this study demonstrate…
Democrazia deliberativa e Convenzione europea dei diritti umani
2010
Deliberative democracy and the European Convention on Human Rights Theories of deliberative democracy have rapidly become very popular amongst political scientists. The central argument of these theories is that democratic legitimacy of lawmaking does not lie (or does not only lie) in the elected character of Parliaments but in public delib- eration processes. Decisions have to be justified by reasons and reasons have to be publicly debated. Legitimacy also depends on the opportunity for citizens to participate effectively in public debates. In this paper I argue that the European Court of Human Rights can be a key player in promoting a democracy based on public deliberation and that in the…
Modelling, Identification and Control of a 5-DOF Shotcrete Robot : Development of a Framework for Automatic Application of Shotcrete for AMV 4200H
2019
Master's thesis Mechatronics MAS500 - University of Agder 2019 Today, process automation is the primary area of development in the shotcrete industry. Automaticshotcrete operations can yield an increase in operational efficiency and personnel safety as well asreductions in cost and environmental impact. This thesis develops a framework for automaticapplication of shotcrete using the AMV 4200H and provides an automatic spraying mode usinginteroceptive sensing. The shotcrete vehicle is equipped with a five degrees-of-freedom manipulatorand is currently operated manually. Our contributions include solving the forward kinematicsthrough the Denavit-Hartenberg convention, and the inverse kinemati…
Freedom of expression and the times of emergency: analysis of Article 15 of the European Convention on Human Rights and derogations made by Turkey an…
2021
COVID-19 pandemic is regarded not to be solely a health crisis, but also human rights crisis. The pandemic limited freedom of movement, freedom of expression, right to education, food security, and other rights. The thesis focuses on the limitation to the freedom of expression in Europe under the ECHR framework during the COVID-19 pandemic in Turkey and Hungary. In Europe, there are more than one hundred alerts on the limitation to the freedom of expression during the pandemic. The thesis is to provide an in-depth understanding and analysis of the derogation procedure of the ECHR under Article 15 ECHR and the limitation procedure to the freedom of expression under Article 10(2) ECHR. Based …
