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 organisatoThe organisation of work in the Swedish building sector is changing due to increased subcontracting and the adoption of construction management. In this study, construction management refers to a specific subcontracting regime, in which contractors externalise all parts of the production process and organise work through subcontractors. Echoing global trends of cost-cutting, this externalisation b

Hybrid perovskites are a novel type of semiconductors that show great potential for solution-processed optoelectronic devices. For all applications, the device performance is determined by the quality of the solution-processed perovskite thin films. During solution processing, the interaction of solvent with precursor molecules often leads to the formation of solvate intermediate phases that may d

In solitary insect pollinators such as butterflies, sensory systems must be adapted for multiple tasks, including nectar foraging, mate-finding, and locating host-plants. As a result, the energetic investments between sensory organs can vary at the intraspecific level and even among sexes. To date, little is known about how these investments are distributed between sensory systems and how it varie

BackgroundKetamine has emerged as a fast-acting and powerful antidepressant, but no head to head trial has been performed, Here, ketamine is compared with electroconvulsive therapy (ECT), the most effective therapy for depression.MethodsHospitalized patients with unipolar depression were randomized (1:1) to thrice-weekly racemic ketamine (0.5 mg/kg) infusions or ECT in a parallel, open-label, non-

A key parameter for the low-temperature magnetic coupling of in dinuclear lanthanide single-molecule magnets (SMMs) is the barrier UFA resulting from the exchange and dipole interactions between the two 4f moments. Here we extend the pseudospin model previously used to describe the ground state of dinuclear endofullerenes to account for variations in the orientation of the single-ion anisotropy ax

Although an increasing number of studies are combining skeletal and neural morphology data in a phylogenetic context, most studies do not include extinct taxa due to the rarity of preserved endocasts. The early Eocene avifauna of the Fur Formation of Denmark presents an excellent opportunity for further study of extinct osteological and endocranial morphology as fossils are often exceptionally pre

The tremendous phenomenological success of the Standard Model (SM) suggests that its flavor structure and gauge interactions may not be arbitrary but should have a fundamental first-principle explanation. In this work, we explore how the basic distinctive properties of the SM dynamically emerge from a unified New Physics framework tying together both flavor physics and Grand Unified Theory (GUT) c

MADS‐box transcription factors are crucial regulators of inflorescence and flower development in plants. Therefore, the recent interest in this family has received much attention in plant breeding programs due to their impact on plant development and inflorescence architecture. The aim of this study was to investigate the role of HvMADS‐box genes in lateral spikelet development in barley (Hordeum

Agricultural output fluctuated worldwide after the emancipation of slaves. The usual explanation is that former slaveholders now lacked labor. This is not the full story: slaves were not just laborers but capital investments to support production. Using databases covering more than 40 years from Stellenbosch in the British Cape Colony, this study measures changes in output before and after emancip

Entangled logics, which attribute meaning to security, characterise the contemporary security field, bringing about broad comprehensions and ambiguous concepts. Civil defence has (re)surfaced as one such concept that is broadly conceived in the official discourses produced by decision-makers. Since security is ultimately enacted by practitioners, alias decision-takers, their interpretations of con

Development economics has long focused on growth patterns to explain countries’ ability to catch up and forge ahead. We argue, however, that resilience to economic shrinking matters more. Using the examples of Brazil and Indonesia, we propose that a framework consisting of social capabilities – namely structural transformation, autonomy, and inclusion – can explain why Indonesia is more resilient

Background: The fractional exhaled nitric oxide (FENO) test is a point-of-care test that is used in the assessment of asthma. Objective: To provide evidence-based clinical guidance on whether FENO testing is indicated to optimize asthma treatment in patients with asthma in whom treatment is being considered. Methods: An international, multidisciplinary panel of experts was convened to form a conse

Att fastställa byggnaders energiprestanda på ett rättvist och transparent sätt är viktigt.För att kunna fastställa en byggnads energiprestanda i drift och för att identifieraprestandaavvikelser behöver uppmätt energianvändning normaliseras. Detta görs genom att korrigera uppmätt energianvändning för avvikelser som förelegat vid mätning jämfört med de förutsättningar som antagits vid projektering.I
