A second order expansion of the eigenvalues of a parameter perturbation of Hermitian matrices is derived using matrix decomposition methods. The method developed is then applied to give a novel proof of a second order approximation of the eigenvalues of a global perturbation of Hermitian matrices first described by M. Carlsson. The result generalizes an approximation given by G.W Stewart which tre
This dissertation is set in the context of the modern space age, which is characterised by an overall increase in space activities on a global scale and a relative increase in private and commercial space activities. Space has become a business case.This study analyses the principle of international responsibility for activities in outer space as mainly codified in Article VI of the Outer Space Tr
Smittspridningen av viruset COVID-19 i början av år 2020 innebar att stater blev tvungna till att vidta restriktioner som lett till stängning av många skolor och bibliotek. Trots nedstängning, har skolor i Sverige kunnat fortsätta undervisningar digitalt. Det finns dock upphovsrättsliga utmaningar med digitala undervisningar, med anledning av upphovsmannens ensamrätt. Syftet med uppsatsen är att uThe outbreak of COVID-19 in the beginning of 2020 has led to states imposing restrictions that cause many schools and libraries to close. Despite the lockdown, it has been possible for schools in Sweden to continue their lectures digitally. However, there are copyright issues to address in the transition to digital teaching because of the right holder's exclusive rights to his or her works. Th
PurposeThe purpose of this paper is to develop a conceptual model that explains how learning processes at the team level connect with individual and organizational levels of learning in technology-based ventures, thereby influencing the evolution of innovation capabilities in the entrepreneurial process.Design/methodology/approachThe 4I organizational learning framework is used as an overarching t
To develop sustainable supply chains in a way that their negative environmental and social effects are minimized, shortand long-term targets should be set. The transformation of supply chains towards these targets calls for the development of innovative strategies and the need to continuously identify, classify, and tackle the challenges that can hinder the execution of such strategies. To develop
This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular info
This paper contains the analysis of the transmission problem with a spherical,dielectric (possibly lossy) shell. The sources to the problem are located insidethe spherical, dielectric shell. Two different source configurations are investigated- an off-center located electric dipole and a circular Huygens surface.An exact modal series solution of the transmission problem is found and thesolution is
The use of participatory action research in media studies is under development and has the last years become notable as a new way of exploring changes that has taken place on the media market the last decades. Media corporations in Sweden continue shutting down local editorial offices and centralize local news reporting to the head editorials. An absence of local reporting in several rural areas iThe use of participatory action research in media studies is under development and has the last years become notable as a new way of exploring changes that has taken place on the media market the last decades.

Increasingly, buildings are becoming complex “systems of systems” with many materials and attributes combining to create a whole that aims to meet a variety of design objectives including but not limited to functionality, aesthetic appeal, sustainability, safety, and security. We are now seeing this complexity move from commercial buildings and iconic structures to encompass even the residential s
An astonishing number of bat fatalities (2,371 belonging to 15 species) were recovered in a provincial surveillance program at wind farms in Cádiz, at the southern tip of Spain, in 2005–2016. We carefully analysed a subset of this sample intending to estimate the true fatality rate in the year 2011, the year for which we had the richest data set (582 fatalities at 38 wind farms). To estimate the t
Almost half of all divorced Swedes today are aged 60+ and many of them are, or have been, a part of a reconstituted family (Bildtgård & Öberg 2014). This means that the probability of having step-grandchildren increases in a life cycle perspective. For those who have never had neither children nor stepchildren, a sibling's or a friend's grandchild can have the same meaning as a step-grandchildAlmost half of all divorced Swedes today are aged 60+ and many of them are, or have been, a part of a reconstituted family (Bildtgård & Öberg 2014).

Post hoc interventions rely on having access to certain personal data - such as the gender, age, ethnicity, and sexual orientation of the persons being evaluated - in order to detect and correct for prejudice. This brings these interventions into possible tension with pertinent data protection legislation, which might restrict the processing of said data. We discuss the compatibility of post hoc i
