Regression testing is expensive and may consume much of organizations’ software development budgets. Thus, it is of interest to reduce the total time devoted to test execution by using test selection techniques. Many techniques have been proposed but few have been evaluated on real-world, large scale systems. In this paper we report on an empirical evaluation of using the class firewall regression

Compulsory school can appear to be uniform because it is common. Its commonness has however more to do with compulsory school attendance than with the fact that all the pupils utilizes education of equal value. Beyond social differences compulsory school creates differences among the pupils just because they are kept in school. In this article three reasons for beeing in school are identified: co

Objective: No method has yet been established to summarise different objective indicators of social outcomes into one score. The study aimed to develop and test a simple, brief and meaningful index of social outcomes that can be used across a broad range of mental health studies and is potentially obtainable from routine documentation. Method: An index capturing employment, accommodation and livin

This study compares the effectiveness of teaching the calculation of frontal plane QRS axis with the use of the classical versus the orderly electrocardiographic limb lead display. Eighty-three students from two environments were randomized into two groups and were taught to determine frontal plane axis with one of the methods. The accuracy and time to determine the axis were tested on 10 electroc

Despite efforts to stimulate the dissemination of green purchasing practices, their uptake in business and industry has so far proven limited. Reasons for the limited progress remain largely unclear. One factor explored in this thesis, is the role of information in the operationalization and dissemination of green purchasing in organizations and supply chains. The importance of knowledge and infor

Background: Although uncomplicated cystitis is often self-limiting, most such patients will be prescribed antibiotic treatment. We are investigating whether treatment of cystitis with an NSAID is as effective as an antibiotic in achieving symptomatic resolution. Methods/Design: This is a randomized, controlled, double blind trial following the principles of Good Clinical Practice. Women between th

Type 2 diabetes (T2D) is a complex disease that is caused by a complex interplay between genetic, epigenetic and environmental factors. While the major environmental factors, diet and activity level, are well known, identification of the genetic factors has been a challenge. However, recent years have seen an explosion of genetic variants in risk and protection of T2D due to the technical developm

'I’m spiritual – not religious' has become a key expression of a new form of globalized religion focussing on a specific notion of spirituality, signifying a universal human essence, located deep inside each individual as a potential for wellbeing and personal transformation. The message is: Spirituality unites us into a single humanity, while religion, with its dogma and rituals, separates us. Th

This article engages with the current debate in childhood research on children’s voices and representation in the research process. In this discussion, the frequent use of drawing techniques in childhood research is often highlighted as especially problematic. While agreeing that there is a need to critically examine the concept of ‘children’s voices’ and the production of ‘voices’ in research, th

Background and Purpose: Natriuretic peptides predict poor outcomes in cardiovascular disease. However, the knowledge of their relationship to stroke is limited and prospective studies from the general population are few. The purpose of this study was to explore the relationship between N-terminal pro-brain natriuretic peptide (NT-proBNP) and midregional pro-atrial natriuretic peptide (MR-proANP) p

Obesity is a highly prevalent complex trait that raises the risk of other chronic diseases such as type 2 diabetes, certain cancers, sleep apnea, and cardiovascular disease, and shortens lifespan. Clinical intervention studies focused on weight loss and epidemiological studies of obesity indicate that genetic variation may modify the relationship between lifestyle behaviors and weight loss or weig
