Background: In today’s business climate, companies need to make sure they have efficient resource management and that the quality of product and services fulfills the customers constant changing expectations, potential regulations, and global environmental policies. Possible approaches for companies to address this is through more strategic purchasing and earlier involvement of purchasers in proc
Context: Several text books and articles published between 2000 and 2002 have attempted to introduce experimental design and statistical methods to software engineers undertaking empirical studies. Objective: This paper investigates whether there has been an increase in the quality of human-centric experimental and quasi-experimental journal papers over the time period 1993 to 2010. Method: 70 exp
Statistical analyses of health effects of air pollution have increasingly used GIS-based covariates for prediction of ambient air quality in "land use" regression models. More recently these spatial regression models have accounted for spatial correlation structure in combining monitoring data with land use covariates. We present a flexible spatio-temporal modeling framework and pragmatic, multi-s
Targino, A. C., Krecl, P., Johansson, C., Swietlicki, E., Massling, A., Coraiola, G. C. & Lihavainen, H. 2013: Deterioration of air quality across Sweden due to transboundary agricultural burning emissions. Boreal Env. Res. 18: 19-36. We analyzed measurements of aerosol and trace-gas concentrations from sites across Sweden before and during a series of agricultural wildland fires in eastern Eu
This research aims to bring a better understanding on the challenges of the current education policy in Ethiopia. The current education policy in Ethiopia has been developed to bring a desirable quality education, yet education quality in Ethiopia is getting worse. Here one can assume that there are several factors contributing to the education policy gaps which quensiquently end up in low educati
Background and purpose: Motion management techniques are important to spare the healthy tissue adequately. However, they are complex and need dedicated quality assurance. The aim of this study was to create a dynamic phantom designed for quality assurance and to replicate a patient's size, anatomy, and tissue density. Materials and methods: A computed tomography (CT) scan of a cancer patient was u
Background: The purpose of this paper is to explore the underlying challenges in the telehealth environment in India and Pakistan that impede the delivery of high-quality images between a patient and health care professional.Method: An exploratory study was conducted among healthcare professionals in India and Pakistan to assess their perceptions regarding image quality, which is used for the diag
Background: The presence of noise is problematic in the analysis and interpretation of the ECG, especially in ambulatory monitoring. Restricting the analysis to high-quality signal segments only comes with the risk of excluding significant arrhythmia episodes. Therefore, the development of novel electrode technology, robust to noise, continues to be warranted. Methods: The signal quality of a nove
The longevity of the almost 100-year-old Ålandic autonomy has been attributed to, among other things, its ability to evolve and adapt to changing circumstances. This position can be problematized and qualified in at least four ways: firstly, most initiatives to develop the autonomy have come from the Ålandic and not the Finnish side; secondly, the processes leading up to the adoptions of new Auton
Ultrasmooth solution-processable quasi-2D perovskite thin films are of critical importance for many optoelectronic devices. In this work, we fabricated an ultrasmooth intermediate-phase free quasi-2D (PEA)2(FA)n−1PbnBr3n+1 perovskite film by using antisolvents with different polarities and boiling points to engineer the crystallization process. The XRD patterns of the perovskite powder showed that
Changes in pupil size can lead to apparent gaze shifts in data recorded with video-based eye trackers in the absence of physical eye rotation. This is known as the pupil-size artifact (PSA). While the PSA is widely reported in desktop eye trackers, it is unknown whether and to what extent it occurs in head-mounted eye trackers. In this paper, we examined the effects of pupil size variations on eye
Market frictions, such as imperfect information or hassle costs, may reduce benefits from market incentives in healthcare settings. We use data from two randomised policy interventions in a Swedish region, which improved the access to provider information and reduced the switching costs of one percent of the adult population and of a sample of new residents. We examine the effects of the intervent
BACKGROUND: Existing conceptions of teaching quality assume that classroom interactions serve as the foundation for effective teaching. The resulting data necessitates analytical approaches capable of extracting the semantics of these interactions.AIM: This study investigates whether and to what extent lesson semantics provide insights into teaching quality (i.e., cognitive engagement, encourageme
Air quality apps are designed to observe air quality and inform publics about it, but also to elicit actions based on anticipated scenarios. As such, they may be seen as anticipatory technologies, cultivating environmental understandings and orienting users toward a specific future. This paper explores the anticipatory assemblages of these apps as well as users’ interactions with these apps and th
One example of a PET exam that suffers from noise problems is [68Ga]Ga-DOTA-TOC, where patients are generally administered between 100 and 200 MBq [68Ga]Ga-DOTA-TOC, irrespective of size. However, a fixed activity can result in low signal-to-noise ratios (SNRs) in larger patients. This study aimed to evaluate the impact on image quality with respect to injected activity and patient habitus through
Popular Abstract in Swedish Det är idag välkänt att patienter med kärlsjukdom i benen har en rad problem som kan påverka deras livskvalitet. Studier har visat att de vanligaste problemen för dessa patienter är trötthet, smärta och begränsad rörelseförmåga. Det är även välkänt att en lyckad kärlkirurgisk behandling ger en snar förbättring av livskvaliteten. Emellertid är kunskapen om varaktigheten The overall aim of this thesis was to investigate quality of life and the meaning of living with peripheral arterial disease (PAD) before and after revascularization in a long-term and methodological perspective. The sample in the first study consisted of 142 patients with PAD who were planned for a revascularization. Quality of life (QoL) assessment with the Nottingham Health Profile (NHP) was ma
Nonmotor symptoms (NMS) are common in patients with established Parkinson's disease (PD) and have a major impact upon quality of life. We investigated the significance of NMS in relation to health-related quality of life (HRQoL) in patients with newly diagnosed PD. Patients and healthy controls were recruited as part of the Incidence of Cognitive Impairment in Cohorts with Longitudinal Evaluation

No. STYR 2016/179 Date 15 March 2018 Regulations for quality assurance and quality enhancement of education at Lund University Background The Higher Education Act (1992:1434) states that the operations of higher education institutions shall be arranged to ensure that
The impact of the operating Ignalina Nuclear Power Plant (INPP) on the contamination of top soil layer with artificial radionuclides has been studied. Results of the investigation of artificial gamma-ray emitting radionuclide distribution in soil in the vicinity of the INPP and distant regions in Lithuania in 1996-2008 (INPP operational period) show that nowadays Cs-137 remains the most important
