Organizations need to make sure that their level of safety is acceptable. Therefore it is important to know which factors contribute to the level of safety and how to monitor and improve these factors. One method used today to evaluate the level of safety in organizations is safety culture measurements. In different contexts, different models of safety culture are used. Safety culture is often con
During the last years a couple of emergencies have affected the Swedish municipality Ljungby and its inhabitants and forced the municipality to initiate emergency responses. Some examples are a flooding that happened during the summer of 2004, the storm Gudrun that occurred in January 2005 and the storm Per that occurred in January 2007. These emergencies, as well as other incidents, are situation
High achievement in school has been associated with increased risk of eating disorders, including anorexia nervosa (AN) and bulimia nervosa (BN), but causality of these relationships is unclear. We sought to examine the association between school achievement and AN or BN in a national cohort and to determine the possible contribution of familial confounding using a co-relative design.
Neighborhood characteristics have been associated with both depression and diabetes, but to date little attention has been paid to whether the association between depression and diabetes varies across different types of neighborhoods. This prospective study examined the relationship between depression, neighborhood deprivation, and risk of type 2 diabetes among 336,340 adults from a national-repre
The aim of this study is to analyse longitudinally, the annual effects of age group and birth cohort on smoking in the Swedish population during a 24-year period and to analyse the smoking trends for different levels of education.
We developed a simple model to calculate the regional deposited dose of submicron aerosol particles in the respiratory system. This model incorporates measured outdoor and modeled indoor particle number size distributions, detailed activity patterns of three age groups (teens, adults, and the elderly), semi-empirical estimation of the regional deposition fraction, hygroscopic properties of urban a
Particles, climate change, and health have thought-provoking interactions. Air pollution is one of the largest environmental problems concerning human health. On the other hand, aerosol particles can have a cooling effect on climate and a reduction of those emissions may result in an increased temperature globally, which in turn may have negative health effects. The objective of this work was to i
Nanoimprint lithography (NIL) is a nonconventional lithographic technique that promises low-cost, high-throughput patterning of structures with sub-10 nm resolution. Contamination of nanoimprint stamps is one of the key obstacles to industrialize the NIL technology. Here, we report two efficient approaches for removal of typical contamination of particles and residual resist from stamps: thermal a
The societal consequences of drug abuse (DA) are severe and well documented, the World Health Organization recommending tracking of population trends for effective policy responses in treatment of DA and delivery of health care services. However, to correctly identify possible sources of DA change, one must first disentangle three different time-related influences on the need for treatment due to
BACKGROUND: -Coagulation allelic variants associated with venous thromboembolism (VTE) have been suggested to be involved in the pathogenesis of ischemic stroke. This nationwide study aimed at determining whether VTE shares familial susceptibility with ischemic stroke. Method and Results-The Swedish Multigeneration Register of 0-75-year-old subjects was linked to the Swedish Hospital Discharge Reg
HUmic-LIke Substances (HULIS) have been identified as major contributors to the organic carbon in atmospheric aerosol. The term "HULIS" is used to describe the organic material found in aerosol particles that resembles the humic organic material in rivers and sea water and in soils. In this study, two sets of filter samples from atmospheric aerosols were collected at different sites. One set of sa
Although cannabis abuse (CA) is known to be associated with schizophrenia, the causal nature of this association is unclear, with prodromal effects complicating its interpretation.
BACKGROUND: The possibility of an association of Graves' disease (GD) with subsequent cancers raised by certain studies. METHODS: Using a database on 18 156 hospitalised GD patients, subsequent cancers were ascertained. RESULTS: Increased risks of thyroid and parathyroid tumours were limited to the early follow-up period, which is probably a surveillance bias. Cancer sites with observed excess inc
Although average life expectancy has increased considerably in Sweden, there is less evidence for improved self-rated health (SRH). We analyzed longitudinal trends in SRH between 1980/1981 and 2004/2005 in age and birth cohort subgroups.
Type 2 diabetes mellitus (T2DM) and HER2 are associated with cancer although the role of HER2 in T2DM is not well defined. Our aim was to investigate the association between HER2 levels and T2DM and whether that association was different in Swedish people born in Iraq or Sweden.
This article presents the analysis of a large survey on file-sharing that was conducted in April 2011 with over 75,000 respondents from all over the world. The study, also known as The Research Bay, due to that it was conducted in collaboration with the infamous BitTorrent site The Pirate Bay, by the Cybernorms research group. The aim of the online study of The Pirate Bay community has been to des
In this chapter, the modelling framework presented in Chap. 5 will be used to perform vulnerability analyses from three perspectives: global vulnerability, critical components, and geographical vulnerability. Two case studies of two real-world interdependent infrastructure systems are performed; one focusing on an electric distribution system coupled with a water distribution system, and one focus
