Purpose: The main purposes of this study is to a) evaluate the suitability of a Varian aS1000 EPID as a safe quality assurance device for control of machine specific parameters, such as linac output, beam quality and beam symmetry, and b) to investigate the usefulness of the SPC concept for evaluation of the obtained data. Method and Materials: Measurements were performed using a Varian Clinac 23

Implementation of open source development practices within commercial settings can bring benefits such as improved source code quality, lower maintenance costs, and increased innovation. However, a widespread in-house implementation of the practices has not been observed. The goal of this research is to understand factors which hinder the implementation. For the purpose, development practices of a

Data centers currently waste a lot of energy, due to lack of energy proportionality and low resource utilization, the latter currently being necessary to ensure application responsiveness. To address the second concern we propose a novel application-level technique that we call event-driven Brownout. For each request, i.e., in an event-driven manner, the application can execute some optional code

This paper addresses one of the important dimensions of the experience of youth in contemporary urban Vietnam; that is their sexual practices, behaviour and attitudes. Within a conceptual framework that focuses on sexuality and social change in a modernising and increasingly open society, and based on data collected from ethnographic fieldwork in Hanoi from 1999 to 2004., this paper describes an e

In this paper, problems related to simulation model documentation and model exchange between users are discussed. Complex simulation models have gained popularity in the environmental field, but require extensive documentation to allow independent implementation. The existence of different simulation platforms puts high demands on the quality of the original documentation. Recent experiences from

This paper introduces the Lang-Track-App, a smartphone application and backend system to aid second language acquisition researchers in implementing the experience sampling method (ESM). Surveying research participants with the Lang-Track-App multiple times per day can yield exceptionally rich data that can be analyzed in multiple ways. This article explains the different Lang-Track-App components

This book focuses on the challenges of living with climate disasters, in addition to the existing gender inequalities that prevail and define social, economic and political conditions. Social inequalities have consequences for the everyday lives of women and girls where power relations, institutional and socio-cultural practices make them disadvantaged in terms of disaster preparedness and experie

Social workers who work within the government with welfare benefits are surrounded by laws, rules, regulations, and ethical codes that have an effect on their everyday work. This study aims to broaden the knowledge regarding social workers’ possibilities to do what they consider best for their clients. This was achieved by conducting semi-structured, qualitative interviews with five social workers

The aim of this thesis is to study how social workers experience and understand the laws they are regulated by, and if they perceive that the laws give them the right conditions to fulfil their purpose(s). Social Services have the important task of protecting society’s vulnerable groups, one of them being children, which entails huge power over other people’s lives, which is why social workers are

Barnfridsbrottet infördes i svensk rätt den 1 juli 2021 och utgör alltså ett förhållandevis nytt brott. Bestämmelsen återfinns i 4 kap. 3 § brottsbalken (1962:700) (BrB) och innebär att det är straffbart att låta barn bevittna vissa i bestämmelsen angivna brott mellan närstående eller tidigare närstående personer till barnet. Syftet med lagstiftningen var att uppmärksamma barn som utsätts för att The criminalization of letting children witness domestic violence entered into force in Swedish law on 1 July 2021 and is thus a relatively new offence. It is found in Section 4. Chapter 3. in the Swedish Criminal Code and means that it is now a criminal offence to expose a child to witnessing domestic violence. The purpose of the penalty provision is to notice and give legislative protection to c

This thesis examines the impact of asexual identification on individuals in Japan. It deploys Identity Process Theory to analyze self-identification processes and argues that the unique experience of asexual individuals requires divergence as a supplementary process. In addition, it examines the threats that self-identified asexual individuals face in their environment and the strategies that they

Ligand exchange on square-planar Pt(1,4-dithiane)2(2+), Pd(1,4-dithiane)2(2+), and Pt(Me2S)4(2+) has been studied as a function of temperature and pressure by H-1 NMR line-broadening, isotopic labeling, and magnetization transfer experiments with deuteriated nitromethane as solvent. Second-order rate constants and activation parameters are as follows: for 1,4-dithiane exchange on Pt(1,4-dithiane)2

A perpetual series of terror attacks have caused the European Union to shake in its foundations. In the face of the escalating transnational threat of terrorism, decision-makers, under severe public pressure, have repeatedly called for deeper international intelligence cooperation. A bold idea currently being debated is the establishment of a new European Intelligence Unit (EIU) in the field of co

The COVID-19 pandemic, climate crisis, and a shifting geopolitical landscape present us with strategic, ethical and planetary dilemmas that demand more reflective action on behalf of actors at every level. The identified challenges of the not-so-distant future require a fundamental transformation of how companies do business, and the role of business schools in shaping the business practices of th

Let w be a word in k variables. For a finite nilpotent group G, a conjecture of Amit states that Nw(1) ≥ | G| k-1, where for g∈ G, the quantity Nw(g) is the number of k-tuples (g1, … , gk) ∈ G(k) such that w(g1, … , gk) = g. Currently, this conjecture is known to be true for groups of nilpotency class 2. Here we consider a generalized version of Amit’s conjecture, which states that Nw(g) ≥ | G| k-

Cross-cultural comparable data collected in several Romance and Scandinavian languages with the help of a series of tasks inspired by Fehr and Rusell’s prototype approach to emotions are analyzed from a perspective that goes beyond the interpretation of prototype theory and aligns with the theory-based approaches to categorization (cfr. the seminal paper by Murphy and Medin 1985). Due to space lim

A polymer foil based array with 9 gold electrodes for chronic electrophysiological recordings in the CNS has been developed. A polymer, SU-8, is pattered using photolithography techniques used every day in micro fabrication. This is beneficial if the electrode would be manufactured on a large scale basis. The technique makes it easy to adapt the array to best fit the structure of interest at the t

Every year, there are more than 2500 new international students coming to Lund University and starting their higher education path. A higher number of foreign students increased the international competitiveness of Lund University, but at the same time the international students had to face many problems for instance, culture shock and language barriers. In this report we focused on issues in teac

Digitalization has grasped almost every aspect of work in Norway in similarity to the developed world. Although many advantages are followed with the implementation of digital tools to bolster the work effort, there is a widespread downside, technostress. This phenomenon engulfs large parts of the workforce and poses a challenge for any foreseeable future, and there is a general lack of research a
