OBJECTIVE: Although claims data are widely used in medical research, their ability to identify persons' health-related conditions has not been fully justified. We assessed the validity of claims-based algorithms (CBAs) for identifying people with common chronic conditions in a large population using annual health screening results as the gold standard.STUDY DESIGN AND SETTING: Using a longitudinal
Microbial communities play a major role in the degradation of soil organic matter (SOM) in soils. Despite its significance, the functional diversity of the highly diverse microbial communities is poorly understood. To address this, we applied a recently developed technique, captured metagenomics, to determine the effects of land-use on the functional genetic diversity of genes involved in the carb
Recently, mass spectrometry (MS) has emerged as an important tool for high-throughput screening (HTS) providing a direct and label-free detection method, complementing traditional fluorescent and colorimetric methodologies. Among the various MS techniques used for HTS, matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) provides many of the characteristics required for high-th
A personal diary may be more appropriate than a questionnaire for assessing self-reported current use of hormone therapy (estrogens, progestagens, or their combination); however, use of a questionnaire is more feasible and less expensive. The authors compared both methods for 16,060 Swedish women aged 45-73 years from the Malmo Diet and Cancer Study (baseline, 1991-1996). In a reliability analysis
It is clinically important to estimate the size of a myocardial infarction (MI) to predict patient prognosis, to determine the ability of a therapy to limit its size, and to evaluate its effect on left ventricular function. Various electrocardiographic methods have been used for these purposes but their accuracies have not been compared with each other using an identical reference population of an
In profit-oriented companies, success is most commonly measured by the amount of profit earned. This thesis aims to probe corresponding measures of success available and employed in non-profit organizations, and to find out the possibility of applying the same or similar techniques in both kinds of organizations. Although in theory Value for Money (VfM = Anticipated Outcomes/Required Resources), a
Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation. The longitudinal movement of art
A project is a temporal organization commonly used in private companies to organize workload. In recent years, projects have also become a way of organize the public sector. One explanation of projects’ increase in popularity is the values; controllability and flexibility. Financial support from the EU and from the state is also distributed to project organizations. How does this way of organizing
Syftet med studien var att undersöka unga kvinnors upplevelser av sexualisering i reklam samt vilka hanteringssätt de använde sig av för att hantera detta i sitt vardagliga liv. Undersökningen grundades i kvalitativ metod med en kritisk realistisk ansats där tematisk analys och semantisk kodning tillämpades för att bearbeta datan. Sju kvinnliga studenter vid Lunds Universitet deltog i semi-struktu
The main objective of this paper is to assess the impact of migration on exports as well as imports, and more specifically, the effect of the Iranian diaspora on trade between their home and host countries. The lifting of the economic sanctions, which was followed after the “Joint Comprehensive Plan of Action”, on Iran throughout 2016 and 2017 is used as a natural experiment to analyse if there is
In terms of EU-accession, the seven countries that used to constitute the republic of Yugoslavia have developed very differently. While Slovenia was one of the countries absorbed during the EU:s eastward expansion of 2004 the other states have struggled in their EU-accession, Croatia being the only state to obtain full membership besides Slovenia. The purpose of this study is to shed a light on th
The purpose of this paper is through an empirical approach understand the dynamics of VIX and investigate to what degree the benchmark computed by CBOE is representative of its definition. The method implemented is of a design where one constructs a hypothetical world in which synthetic options data are produced by the Bates-Heston model. This implies an underlying and known volatility with chosen
Professional counselors are often seen as responsible for highlighting the need of, and to operate the social work in healthcare. To have that expertise in an otherwise medical context can lead to it being a difficult task. It is also suggested that the social worker’s role and professional identity is vague, which also influences social worker’s jurisdictional work. The aim of this study was to i

In this work we report results of ferromagnetic resonance studies of a 6% 15 nm (Ga,Mn)As layer, deposited on (001)-oriented GaAs. The measurements were performed with in-plane oriented magnetic field, in the temperature range between 5 K and 120 K. We observe a temperature induced reorientation of the effective in-plane easy axis from [(1) over bar 10] to [110] direction close to the Curie temper
Every second fish consumed by humans today is produced in aquaculture, and the main protein source in the fish feed is fishmeal. For every farmed salmonid, 1.8 fish are used in that fish’s feed. Hence, there is a great need of alternative protein sources to make aquaculture sustainable. The bacterium Caldicellulosiruptor saccharolyticus, used experimentally for hydrogen production, has a protein c
This thesis deals with manual control of unstable systems, subject to control signal constraints. Allocation of control authority is critical in this situation. The manual control, or reference following, must not be performed at the risk of loosing stability. The conflicting objective is to achieve acceptable reference following performance. Design of control systems under such circumstances is c
The overall aim of this project was to make an everyday life for people with reduced mobility better. This crutch helps its users to perform everyday activities easier and feel more comfortable. It provides: - Better mobility; - Better stability, - Comfort; - Possibility to switch from one type of the crutch to another that not only allows stressed body parts to relax but also helps a user to be
