Poor collaboration among professional groups may be a major cause of incoherent patient pathways in hospital settings. For over a decade, interprofessional collaboration (IPC) have been stressed as an effective method to enhance the delivery of patient care. This article presents a theory-based stakeholder evaluation of the implementation of an intervention aiming to implement the concept of IPC in a Danish regional hospital from 2012 to 2015. Involving five departments and eight professions, the intervention aimed at developing coherent practices across health professions by optimising patient pathways with the establishment of interprofessional teams as a core element...

We describe how self-reported health (SRH) varies with gender and John Henryism (a strong behavioral predisposition to engage in high-effort coping to overcome adversity) in a low income sample of Serbian Roma. Data were collected in 2016 in several Roma settlements around Belgrade, Serbia. The sample consisted of 90 men and 112 women. In addition to John Henryism (JH), measured by a Serbian version of the John Henryism Scale, demographic data and data on SRH and family relationships dynamics were collected...

The excitotoxic theory of Parkinson's disease (PD) hypothesises that a pathophysiological degeneration of dopaminergic neurons stems from neural hyperactivity at early stages of disease, leading to mitochondrial stress and cell death. Recent research has harnessed the visual system of Drosophila PD models to probe this hypothesis. Here, we investigate whether abnormal visual sensitivity and excitotoxicity occur in early-onset PD Drosophila models DJ-1Δ72, DJ1-Δ93, and PINK15. We used an electroretinogram to record steady state visually evoked potentials driven by temporal contrast stimuli...

V A Levashov
We studied the connection between the structural relaxation and viscosity for a binary model of repulsive particles in the supercooled liquid regime. The used approach is based on the decomposition of the macroscopic Green-Kubo stress correlation function into the correlation functions between the atomic level stresses. Previously we used the approach to study an iron-like single component system of particles. The role of vibrational motion has been addressed through the demonstration of the relationship between viscosity and the shear waves propagating over large distances...

Unlike reverse osmosis (RO) that is dominated by the hydraulic pressure differential, forward osmosis (FO) uses the osmotic pressure gradient as the driving force between a dilute feed solution and a concentrated draw solution across a membrane. High pressure is not required in FO, which means that FO can be used as an alternative to RO as an energy-saving separation process in desalination technology. However, a major limiting factor of the FO process is the internal concentration polarization (ICP). Because of the stagnant environment inside the porous supporting layer of a FO membrane, it is difficult to mitigate the ICP by simply increasing the shear stress or promoting turbulence...

Hyo-Eun Jung, Mincheol Shin
First-principles density functional theory (DFT) based device simulations are performed for Si ultra-thin-body (UTB) field effect transistors with the explicit SiO2 atoms in the gate dielectric. In order to evaluate the Si/SiO2 interface stress effects on the UTB device performance, the interface stress tensor is extracted from the Si/SiO2 atomic structure by DFT calculations. The influence of the interface stress on the transport properties is examined through full quantum mechanical non-equilibrium Green's function calculations...

Numerous studies have linked the high rates of traumatic events experienced by refugees to the elevated rate of mental health problems in these populations. A growing body of evidence has also highlighted the importance of considering postmigratory stressors when making sense of displaced person distress. This study explored the relationship between mental health and postmigratory stress for asylum seekers and refused asylum seekers in Britain. The study further examined if those refused asylum experienced elevated distress and postmigratory stress compared to those awaiting the outcome of asylum applications...

The typical practice of averaging group performance during extinction gives the impression that responding declines gradually and homogeneously. However, previous studies of extinction in human infants have shown that some individuals persist in responding, whereas others abruptly cease responding. As predicted by theories of control, the infants who quickly resign typically display signs of sadness and despair when the expected reward is omitted. Using genetically diverse mice, here we observed a similar pattern of individual differences and the associated phenotypes...

BACKGROUND: Empirical research demonstrates that there is a tendency to administer tumor-directed therapy to patients with advanced cancer close to death, especially if they are young. The aim of this qualitative study was to understand oncologists' treatment decisions and oncology nurses' perception of these decisions in young adult patients and to investigate the extent to which young age was a factor in cancer treatment decisions. MATERIALS AND METHODS: We conducted 29 face-to-face interviews with oncologists and oncology nurses at the Department of Hematology and Oncology at the University Hospital in Munich, Germany...

International challenges such as climate change, poverty, and intergroup conflict require countries to cooperate to solve these complex problems. However, the political tide in many countries has shifted inward, with skepticism and reluctance to cooperate with other countries. Thus, cross-societal investigations are needed to test theory about trust and cooperation within and between groups. We conducted an experimental study in 17 countries designed to test several theories that explain why, who, and where people trust and cooperate more with ingroup members, compared with outgroup members...

In this paper, nonlinear behavior of black phosphorus crystals is investigated in tandem with dispersion corrected density functional theory (DFT-D) analysis under uniaxial loading. According to the distinguished anisotropic behavior of black phosphorus due to its morphological anisotropy, a hyperelastic anisotropic (HA) model named continuum-DFT is established to predict nonlinear behavior of the material. In this respect, uniaxial tensile Cauchy stresses are employed on both the DFT-D and HA models along zig-zag direction...

Pumping of fluids with precise control is one of the key components in a microfluidic device. The electric field has been used as one of the most popular and efficient nonmechanical pumping mechanism to transport fluids in microchannels from the very early stage of microfluidic technology development. This review presents fundamental physics and theories of the different microscale phenomena that arise due to the application of an electric field in fluids, which can be applied for pumping of fluids in microdevices...

Saxitoxins (STXs) are potent neurotoxins that block voltage-gated channels in neurons and induce cytotoxicity. These toxins not only can generate reactive oxygen species but also can alter antioxidant levels, promoting oxidative stress. Under this pro-oxidant situation, the use of the antioxidant lipoic acid (LA) can represent a chemoprotective alternative to minimize the deleterious effects induced by neurotoxins as STXs. P-glycoprotein (P-gp) is a well-known ATP-binding cassette (ABC) transporter that plays a crucial role in the extrusion of toxic substances, decreasing their accumulation and potential intracellular effects in virtue of its broad substrate specificity, its expression in many excretory tissues and its large efflux capacity...

Primary polydipsia (PP) has been defined as excessive intake of fluids. However, the pathogenesis of PP remains unexplored. Different theories include a dysfunction in the thirst mechanism, involvement of the hippocampus, stress-reducing behaviour and lesion occurrences in specific areas of the brain. Most studies have been performed in the psychiatric setting, indicating that PP coincides with schizophrenia, anxiety disorder and depression. However, an increasing number of case reports emphasise the incidence of PP in non-psychiatric patients...

Hyperspectral imaging is a technology that can be used to monitor plant responses to stress. Hyperspectral images have a full spectrum for each pixel in the image, 400-2500 nm in this case, giving detailed information about the spectral reflectance of the plant. Although this technology has been used in laboratory-based controlled lighting conditions for early detection of plant disease, the transfer of such technology to imaging plants in field conditions presents a number of challenges. These include problems caused by varying light levels and difficulties of separating the target plant from its background...

We used quantitative genetics to test a controversial theory of heat stress, in which animals overheat when the demand for oxygen exceeds the supply. This theory, referred to as oxygen- and capacity-limited thermal tolerance, predicts a positive genetic correlation between hypoxia tolerance and heat tolerance. We demonstrate the first genetic correlation of this kind in a model organism, Drosophila melanogaster Genotypes more likely to fly under hypoxic stress (12% O2) were also more likely to fly under heat stress (39°C)...

We apply a recently developed method [S. Sen and A. Kundagrami, J. Chem. Phys. 143, 224904 (2015)], using a phenomenological expression of osmotic stress, as a function of polymer and charge densities, hydrophobicity, and network elasticity for the swelling of spherical polyelectrolyte (PE) gels with fixed and variable charges in a salt-free solvent. This expression of stress is used in the equation of motion of swelling kinetics of spherical PE gels to numerically calculate the spatial profiles for the polymer and free ion densities at different time steps and the time evolution of the size of the gel...

Violaine Michel Lange, Maria Messerschmidt, Kasper Boye
This paper investigates the difference between the production of grammatical determiners and lexical determiners in the production of adjective-noun phrases (NPs) in Danish. Models of sentence processing (Garrett in Psychology of learning and motivation, Academic press, New York, pp 133-177, 1975; Bock in J Mem Lang 26(2):119-137, 1987) suggest that the phonological encoding stage of grammatical items can only be specified once lexical items have been phonologically encoded. In their usage-based linguistic theory of the grammar-lexicon distinction, Boye and Harder (Lang 88(1):1-44, 2012) propose that this later encoding of grammatical elements is motivated by two specific features of grammatical elements...

In this paper, it is argued that Jakob von Uexküll's "search image" notion, the original version of this notion within ethology, is still of use. A search image, in Uexküll's sense, is an imagined object that an organism has in mind when it searches for something. Uexküll's conception of the search image is useful both for understanding the theoretical context of contemporary notions of search images, and with an eye to envisioning possible future developments of the idea. Uexküll's classical notion differs from contemporary versions in that it has a wider application, and is therefore of greater relevance to theoretical biology and cognitive science...

Neuroblastoma is a childhood tumor that is derived from the sympathetic nervous system. In recent years, great progress has been made in our understanding of neuroblastoma. However, applying theories to improve disease outcomes remains challenging. In this study, we observed that calcium homeostasis endoplasmic reticulum protein (CHERP) was involved in the maintenance of neuroblastoma cell proliferation and tumorigenicity. Moreover, elevated CHERP expression was positively correlated with poor patient survival, whereas low CHERP expression was predictive of better outcomes...
