Aims: Climate change is known to drive both the reshuffling of whole assemblages and range shifts of individual species. Less is known about how local colonizations and extinctions of individual species contribute to changes at the community level. Our aim was to estimate the contribution of individual species to a change in community composition attributed to climate change and to relate these sp

At the end of life, when cure or meaningful prolongation of life is no longer available, relief of suffering is the overriding goal. In certain circumstances standard treatments may fall short of this goal, and palliative sedation (PS) to unconsciousness can be applied as a ultimum refugium.We cared for a 4-year old boy with a brain-stem tumor. In spite of all curative treatment efforts the tumor

Global climate change is a major threat to biodiversity. Large-scale analyses have generally focused on the impacts of climate change on the geographic ranges of species and on phenology, the timing of ecological phenomena. We used long-term monitoring of the abundance of breeding birds across Europe and the United States to produce, for both regions, composite population indices for two groups of

The standard requirement of informed consent cannot be met when potential research subjects are decisionally incapacitated due to e.g. dementia, intellectual disabilities, or other mental health problems. Such research subjects are generally recognized as being in need of special protection, particularly when the relevant research cannot be expected to benefit the participating individuals themsel

Human motion analysis in images and video, with its deeply inter-related 2D and 3D inference components, is a central computer vision problem. Yet, there are no studies that reveal how humans perceive other people in images and how accurate they are. In this paper we aim to unveil some of the processing—as well as the levels of accuracy—involved in the 3D perception of people from images by assess

Aims: The primary objective of this study was to analyze the association between alcohol consumption and short-term response to treatment (post intervention) in male patients with gambling disorder enrolled in a group cognitive behavioral therapy (CBT) program. Methods: The sample consisted of 111 male individuals with a diagnosis of Gambling Disorder, with a mean age of 45 years (SD = 12.2). All

This study reinvestigates the relationship between unemployment and crime, but is the first to focus explicitly on the effects of long-term unemployment on crime. A unique finding is that long-term unemployment shows a strong association with violent crime, an effect which is greater than that of total unemployment on property crime in this and most previous studies. Long-term unemployment thus id

Adding to approaches highlighting network dynamics as a basis for regional economic development, increased attention is paid to institutions as contextual factors contributing to explaining how and why economies change. Research has shown that firms tend to react differently to the same institutional configurations, with the main explanatory factors being their sectoral backgrounds and intra-firm

We present the WD2014 chronology for the upper part (0-2850 m; 31.2 ka BP) of the West Antarctic Ice Sheet (WAIS) Divide (WD) ice core. The chronology is based on counting of annual layers observed in the chemical, dust and electrical conductivity records. These layers are caused by seasonal changes in the source, transport, and deposition of aerosols. The measurements were interpreted manually an

This work presents a digital calibration technique in continuous-time (CT) ΔΣ analog to digital (A/D) converters. The converter is clocked at 144MHz with a low oversampling ratio (OSR) of only 8. Dynamic element matching (DEM) is not efficient to linearize the digital to analog converter (DAC) when the OSR is very low. Therefore, non-idealities in the outermost multi-bit feedback DAC are measured

A themed journal issue which contains six commissioned essays + an editorial about the phenomenon of sex in the cinema, television and on the internet since the historical breakthrough of sex research by Alfred C. Kinsey in the late 1940s. The essays span a wide array of topics including, to name a few, the developments within obscenity law in the US, sex in the work of European art cinema auteurs

Film International (published by Intellect, Bristol, UK) is dedicating a special journal issue to “Making Movies in Europe: Production, Industry, Policy” and cordially invites proposals on this theme. Studies of contemporary as well as historical filmmaking practices are welcome. Possible areas include, but are not limited to:-the specific workings of national cinema industries (e.g. specific nati

Internationally fragmented production processes have highlighted the need of efficient sourcing from foreign suppliers. This paper aims to investigate how exports of final goods are affected by better access to foreign intermediate inputs. In particular, the paper empirically tests whether expanding the set of available intermediate input suppliers through preferential rules of origin liberalisati

Ornithine decarboxylase (ODC), a key enzyme in polyamine biosynthesis, was measured in the three major salivary glands of rats and mice. Enzyme activity and glandular putrescine content increased after continuous stimulation of the parasympathetic or sympathetic salivary nerves for 3 h. The activity was markedly reduced in animals fasted for 24 h to decrease nervous-reflex activation of the glands

The late posterior negativity (LPN) is an ERP effect frequently reported in episodic memory tasks. In 2003, we proposed that both non-mnemonic action monitoring processes and reconstructive mnemonic processes contribute to the LPN. Here, we review more recent studies and provide additional evidence that the LPN reflects dissociable (though not mutually exclusive) mnemonic and non-mnemonic processe
