Barriers and facilitators for BIM use among Swedish medium-sized contractors - “We wait until someone tells us to use it”

Background The pace of diffusion of BIM (Building Information Modelling) use is considered to increase with governmental initiatives in which public clients in countries like Finland, Singapore, United Kingdom, and Sweden begin requiring BIM as a part of the project delivery. Currently, larger contractor firms use BIM to a certain extent. However, BIM use by mid-sized contractor ...

Bending back stress chains and unique behaviour of granular matter in cylindrical geometries

We analyse the general solutions for the stress field in planar annuli of isostatic media, a model often used for marginally rigid granular materials in Couette cells. We demonstrate that these solutions are much richer than in rectangular symmetries. Even for uniform media, stress chains are found to curve, broaden away from the stress source, attenuate and leak stress into a cone ...

Prognostic Value of Computed Tomography: Measured Parameters of Body Composition in Primary Operable Gastrointestinal Cancers

Background Previous reports suggest that body composition parameters can be used to predict outcomes for patients with gastrointestinal (GI) cancers. However, evidence for an association with long-term survival is conflicting, with much of the data derived from patients with advanced disease. This study examined the effect of body composition on survival in primary operable GI ...

Prognosis of cirrhotic patients admitted to intensive care unit: a meta-analysis

Background The best predictors of short- and medium-term mortality of cirrhotic patients receiving intensive care support are unknown. Methods We conducted meta-analyses from 13 studies (2523 cirrhotics) after selection of original articles and response to a standardized questionnaire by the corresponding authors. End-points were in-ICU, in-hospital, and 6-month mortality in ICU ...

Dynamic political contexts and power asymmetries: the cases of the Blue Nile and the Yarmouk Rivers

This paper explores the evolving patterns of hydropolitical relations in the dynamic contexts of Yarmouk and Blue Nile Rivers in comparison. The analysis aims at shedding light over the complex implications that recent political and social changes have aroused for the water disputes between Jordan and Syria on the one hand, and Ethiopia and Egypt on the other. In both basins, ...

Global hydrogen reservoirs in basement and basins

Background Hydrogen is known to occur in the groundwaters of some ancient cratons. Where associated gases have been dated, their age extends up to a billion years, and the hydrogen is assumed also to be very old. These observations are interpreted to represent the radiolysis of water and hydration reactions and migration of hydrogen into fracture systems. A hitherto untested ...

From working collections to the World Germplasm Project: agricultural modernization and genetic conservation at the Rockefeller Foundation

This paper charts the history of the Rockefeller Foundation’s participation in the collection and long-term preservation of genetic diversity in crop plants from the 1940s through the 1970s. In the decades following the launch of its agricultural program in Mexico in 1943, the Rockefeller Foundation figured prominently in the creation of world collections of key economic crops. ...

Nudge management: applying behavioural science to increase knowledge worker productivity

Knowledge worker productivity is essential for competitive strength in the digital century. Small interventions based on insights from behavioural science makes it possible for knowledge workers to be more productive. In this point of view article, we outline and discuss a new management style which we label nudge management.

Damage from lava flows: insights from the 2014–2015 eruption of Fogo, Cape Verde

Fast-moving lava flows during the 2014–2015 eruption of Fogo volcano in Cape Verde engulfed 75% (n = 260) of buildings within three villages in the Chã das Caldeiras area, as well as 25% of cultivable agricultural land, water storage facilities and the only road into the area. The eruption had a catastrophic impact for the close-knit communities of Chã, destroying much of their ...

A global optimisation approach to range-restricted survey calibration

Survey calibration methods modify minimally sample weights to satisfy domain-level benchmark constraints (BC), e.g. census totals. This allows exploitation of auxiliary information to improve the representativeness of sample data (addressing coverage limitations, non-response) and the quality of sample-based estimates of population parameters. Calibration methods may fail with ...

Multimodality management and outcomes of brain arterio-venous malformations (AVMs) in children: personal experience and review of the literature, with specific emphasis on age at first AVM bleed

Purpose The purpose of this paper is to study the presentation and analyse the results of multimodality treatment of brain arterio-venous malformations (AVMs) in children at our centre and review age at first AVM rupture in the literature. Methods Of 52 patients aged <18 years, 47 with brain AVMs (27 males and 20 females) aged 4–17 years (mean 12.2) were retrospectively reviewed. ...

The impact of cognitive training in substance use disorder: the effect of working memory training on impulse control in methamphetamine users

Objectives Impulsivity is a vulnerability trait for poor self-regulation in substance use disorder (SUD). Working memory (WM) training improves impulsivity and self-regulation in psychiatric disorders. Here we test WM training in methamphetamine use disorder (MUD). Methods There are 15 MUD patients receiving inpatient treatment as usual (TAU) and 20 who additionally completed WM ...

The Scientific Perspective on Moral Objectivity

The naturalistic approach to metaethics is sometimes identified with a supervenience theory relating moral properties to underlying descriptive properties, thereby securing the possibility of objective knowledge in morality as in chemistry. I reject this approach along with the purely anthropological approach which leads to an objectionable form of relativism. There is no single ...

Automated guided vehicle mission reliability modelling using a combined fault tree and Petri net approach

Automated guided vehicles (AGVs) are being extensively used for intelligent transportation and distribution of materials in warehouses and autoproduction lines due to their attributes of high efficiency and low costs. Such vehicles travel along a predefined route to deliver desired tasks without the supervision of an operator. Much effort in this area has focused primarily on route ...

Should We Genetically Select for the Beauty Norm of Fair Skin?

Fair skin is often regarded as a beauty ideal in many parts of the world. Genetic selection for non-disease traits may allow reproducers to select fair skin for the purposes of beauty, and may be justified under various procreative principles. In this paper I assess the ethics of genetic selection for fair skin as a beauty feature. In particular, I explore the discriminatory ...

MtDNA-maintenance defects: syndromes and genes

A large group of mitochondrial disorders, ranging from early-onset pediatric encephalopathic syndromes to late-onset myopathy with chronic progressive external ophthalmoplegia (CPEOs), are inherited as Mendelian disorders characterized by disturbed mitochondrial DNA (mtDNA) maintenance. These errors of nuclear-mitochondrial intergenomic signaling may lead to mtDNA depletion, ...

Equilibrium in risk-sharing games

The large majority of risk-sharing transactions involve few agents, each of whom can heavily influence the structure and the prices of securities. In this paper, we propose a game where agents’ strategic sets consist of all possible sharing securities and pricing kernels that are consistent with Arrow–Debreu sharing rules. First, it is shown that agents’ best response problems have ...
