The unreflective practitioner : A pilot study on functional stupidity and social work

This study’s aim was to operationalise and test a model of functional stupidity, a form of unreflective compliance, and explore its appropriateness for understanding how social workers comply with and motivate performing morally or professionally problematic tasks. A sample of 120 social workers from six municipalities in Sweden self-completed a questionnaire containing 20 Likert-type items denoti

Ecological indicator and traits values for Swedish vascular plants

We introduce and provide a new data-set of species-specific ecological indicator values (alternative ‘Ellenberg values’ for climatic variables, light, moisture, soil reaction/pH, salinity, nitrogen and phosphorus plus response to management and disturbance), physiological and reproductive traits (including symbionts, phenology, pol- linators, nectar production, seed properties), indices of relevanWe introduce and provide a new data-set of species-specific ecological indicator values (alternative ‘Ellenberg values’ for climatic variables, light, moisture, soil reaction/pH, salinity, nitrogen and phosphorus plus response to management and disturbance), physiological and reproductive traits (including symbionts, phenology, pol- linators, nectar production, seed properties), indices of relevan

Functional morphology of mammalian rhinariumn skin

The naked skin surrounding the nostrils in most mammals is called a rhinarium. Rhinarium skin exhibits several unique characteristics, including an ultrastructure of pits or furrows on surface corneocytes, formed in a unique epidermal differentiation process (Paper I). Rhinarium skin is often assigned a mechanosensory function because the rhynoglyphic pattern of epidermal domes, ridges or polygons

Structural analysis of slender glass panel subjected to static and impact loading

Slender glass panels are widely used as storefronts and indoor separating walls in shopping malls and public buildings. To ensure that the design and construction is technically safe for general use and that it meets current and accepted technical standards, in-situ testing is required by the building administrator or authorities. A case study was performed of an indoor glass lantern in a public b

A global meta-analysis of greenhouse gases emission and crop yield under no-tillage as compared to conventional tillage

No-tillage (NT) practice is extensively adopted with aims to improve soil physical conditions, carbon (C) sequestration and to alleviate greenhouse gases (GHGs) emissions without compromising crop yield. However, the influences of NT on GHGs emissions and crop yields remains inconsistent. A global meta-analysis was performed by using fifty peer-reviewed publications to assess the effectiveness of

Religiosity and discrimination against same-sex couples : The case of Portugal's rental market

We measure and analyze discriminatory behavior against same-sex couples trying to rent an apartment in Portugal and pay special attention to the role of religiosity. This is the first correspondence field experiment investigating discrimination against this minority group in Portugal, and the first one to highlight religion as a factor of importance. In our experiment, four type of applicants vary

Toxin-Based Rodent Models of Parkinson’s Disease

A major pathological hallmark of Parkinson’s disease (PD) is a severe degeneration of dopamine (DA)-producing neurons in the substantia nigra pars compacta (SNc) projecting to the motor part of the striatum. Therefore, there is a long-standing interest in using animal models with severe nigrostriatal degeneration for experimental research. Pathophysiological and behavioral features of PD are best

Maize residue effects on PM2.5, PM10, and dust emission from agricultural land

Atmospheric particulate matter and dust from agricultural land significantly affect air quality and human health in nearby residential areas. To quantify these air pollutants, it is important to estimate the vertical atmospheric particulate matter PM2.5, PM10, and dust flux using observations and validated models. To the authors´ knowledge, this has previously not been performed for semi-humid agr

CD163+ macrophages are associated with a vulnerable plaque phenotype in human carotid plaques

Macrophages are a functionally heterogeneous group of immune cells abundant in atherosclerotic plaques. Macrophages expressing CD163 are associated with intraplaque hemorrhage and have previously been considered atheroprotective. However, in a recent study CD163-deficient atherosclerotic ApoE−/− mice exhibited smaller and less complex plaques, suggesting a proatherogenic role of CD163. Previous sm

Effects of ambient methanol on pollutants formation in dual-fuel spray combustion at varying ambient temperatures : A large-eddy simulation

Large-eddy simulation with a finite-rate chemistry model is carried out to investigate the formation of soot and nitrogen oxides (NOx) in the dual-fuel spray combustion. Liquid n-heptane is injected into a constant volume chamber, filled with a premixed methanol–air mixture with an equivalence ratio (ϕm) of 0.3. Three dual-fuel cases are simulated under initial temperatures of 900, 950 and 1000 K.

Methyl-3-hexenoate combustion chemistry : Experimental study and numerical kinetic simulation

This work represents a detailed investigation of combustion and oxidation of methyl-3-hexenoate (CAS Number 2396-78-3), including experimental studies of combustion and oxidation characteristics, quantum chemistry calculations and kinetic model refinement. Following experiments have been carried out: Speciation measurements during oxidation in a jet-stirred reactor at 1 atm; chemical speciation me
