Labour management in the past has been the studied by researchers from various disciplines and perspectives. Among labour economists and economic historians, there is an emerging current that aims to test hypotheses derived from theories about internal labour markets. So far, most studies have focused on companies whose workforces have been stable or expanding over time. This paper analyzes the in

BACKGROUND: Nosocomial outbreaks of coronavirus disease 2019 (COVID-19) can have devastating consequences from both a resource cost and patient healthcare perspective. Relying on reverse transcription-polymerase chain reaction (RT-PCR) for identifying infected individuals may result in missed cases. Screening for antibodies after an outbreak can help to find missed cases and better illuminate rout

BACKGROUND: Single nucleotide polymorphisms (SNPs) in the promoter region of CRYAB gene have been associated with in multiple sclerosis. CRYAB gene, which encodes alpha B-crystallin (a member of small heat shock protein), was reported as a potential autoimmune target. In this study we investigated whether SNPs in the promoter region of CRYAB gene were also important in the etiology of Type 1 diabe

BACKGROUND: Current global food systems threaten human health and environmental sustainability. In 2019, the EAT-Lancet Commission on healthy diets from sustainable food systems defined the first global reference diet to improve both areas, but there is no consensus on how to quantify the EAT-Lancet reference diet as a diet index and its relation to mortality has not been widely studied.OBJECTIVE:

Svensk byggindustri är under förändring. Stora delar av produktionen läggs idag ut på entreprenad och byggföretag förlitar sig på underentreprenörer i större utsträckning än tidigare. Som en del av en global trend av kostnadsreducering inom byggindustrin, försöker byggföretag minimera antalet anställda hantverkare och istället utkontraktera arbete till underentreprenörer i strävan efter organisato

BACKGROUND: Children with cerebral palsy (CP) form a heterogeneous group and may have risk or protective factors for fractures compared with typically developing children. The fracture sites may also differ from those of children who do not have CP. We analyzed the fracture epidemiology in a total population of children with CP.METHODS: This was a retrospective registry study based on data from th

Recently, it has been shown and validated that presence and severity of emphysema on computed tomography could be estimated by a novel spirometry based index, the emphysema severity index (ESI). However, the clinical relevance of the index has not been established. We conducted cox-regression analyses with adjustment for age, smoking, sex, forced expiratory volume in 1 s (FEV1) and forced vital ca

Objective: (1) investigate the associations of attention-deficit/hyperactivity disorder (ADHD) with systolic and diastolic blood pressure, resting heart rate, pulse pressure (PP), physical fitness, and BMI; (2) explore whether cardiovascular risk factors and ADHD share genetic and environmental influences; (3) assess if pharmacological treatment for ADHD influences these associations. Methods: We
