To assess the role of feral oilseed rape (OSR) plants as resources for pollinators and avenues for gene flow, we compared occurrence of feral populations in standardized agricultural landscapes, using a landscape ecological approach. The occurrence of feral and volunteer populations was investigated in relation to differences in road length and width, number of OSR fields, and landscape scale. The

We develop a two-country, two-sector overlapping generations model to examine the effect of population aging on the real exchange rate (RER). While an older population raises the relative demand for nontradables (a feature of structural transformation) putting upward pressure on relative prices thus appreciating the RER, it also implies a lower real interest rate (distinctive of secular stagnation

We present an epistemological schema of natural sciences inspired by Peirce’s pragmaticist view, stressing the role of the phenomenological map, that connects reality and our ideas about it. The schema has a recognisable mathematical/logical structure which allows to explore some of its consequences. We show that seemingly independent principles as the requirement of reproducibility of experiments

In this paper we investigate the specific mechanisms of British financial influence in the Cape Colony during the diamond mining boom of the late nineteenth century. We do so by offering a detailed exposition of the uneasy marriage between the colonial state and private business sector in the context of the economics and dynamics of extractivism in the periphery. This allows us to encapsulate the

Pre-transitional justice activities that expose past injustices during entrenched conflicts can incite strong reactions among actors who feel threatened by or dislike such activities, and who thus attempt to silence controversial truths. This article illuminates how attempts to silence controversial truths, in parallel with shutting down debate, can also have the unintended outcome of enlarging pu

Understanding the origins of biodiversity has been an aspiration since the days of early naturalists. The immense complexity of ecological, evolutionary, and spatial processes, however, has made this goal elusive to this day. Computer models serve progress in many scientific fields, but in the fields of macroecology and macroevolution, eco-evolutionary models are comparatively less developed. We p

Every aspect of vision, from the opsin proteins to the eyes and the ways that they serve animal behavior, is incredibly diverse. It is only with an evolutionary perspective that this diversity can be understood and fully appreciated. In this review, I describe and explain the diversity at each level and try to convey an understanding of how the origin of the first opsin some 800 million years ago

European VAT and the Sharing Economy aims to understand whether the current European Value Added Tax (EU VAT) system is sufficiently equipped to deal with the ongoing transformation of the supply chain as well as the increasing digitalization of the economy ushered in by the rise of multisided digital platforms. New digital platforms such as those of the sharing economy, have dramatically expanded

The Tulving-Wiseman law is an empirical law that describes the relation between successive tests of recognition and recall of the same set of individual subject-items. It relates the probability of recognising the recallable items to the probability of recognising all the items, regardless of whether they are recalled. The relation represents a moderate degree of dependency between the tests. Two

Woese and Fox's 1977 paper on the discovery of the Archaea triggered a revolution in the field of evolutionary biology by showing that life was divided into not only prokaryotes and eukaryotes. Rather, they revealed that prokaryotes comprise two distinct types of organisms, the Bacteria and the Archaea. In subsequent years, molecular phylogenetic analyses indicated that eukaryotes and the Archaea

The paper discusses what kind of truth bearer, or truth-ascription, a deflationist should take as primary. I first present number of arguments against a sententialist view. I then present a deflationary theory which takes propositions as primary, and try to show that it deals neatly with a wide range of linguistic data. Next, I consider both the view that there is no primary truth bearer, and the

Background: While cognitive-behavioral therapy (CBT) is the gold-standard psychological treatment for major depression (MD), non-response and lacking stability of treatment gains are persistent issues. Potential factors influencing treatment outcome might be lifetime trauma history and possibly associated primarily prefrontal-cortex- and hippocampus-dependent cognitive alterations. Method: We inve

Realizing that a changing society is in constant need of redefinition, the rural-urban distinction is especially important to look systematically into. One reason is that although the outdatedness of the rural-urban dichotomy is widely acknowledged, it is still largely sustained, not least in ‘rural’ and ‘urban’ development endeavors, which are often conducted separately. Such practice may seem qu

We study the chemical evolution of Zr, La, Ce, and Eu in the Milky Way discs and bulge by means of chemical evolution models compared with spectroscopic data. We consider detailed chemical evolution models for the Galactic thick disc, thin disc, and bulge, which have been already tested to reproduce the observed [α/Fe] versus [Fe/H] diagrams and metallicity distribution functions for the three dif

This article discusses the implications of the United Nations’ Convention on the Rights of Persons with Disabilities (“CRPD”) for domestic policies on research involving persons with disabilities, including those with limited decision-making abilities. It starts with an examination of the protection the Convention affords to persons with disabilities against being enrolled in research projects, an

INTRODUCTION: Despite much literature on reference values of acid-base status in umbilical cord blood at birth, there are as yet no studies performed to determine gestational age-dependent references in cord venous blood and no studies on preterm acid-base standards. Similarly, the normal reference range of Apgar scores for term and preterm infants has not yet been determined.MATERIAL AND METHODS:

In the European Union, the setting of Operational Groups (OG) is supported by the European Innovation Partnership to tackle specific problems and favor innovation in agriculture. They constitute an important aspect of the current Common Agricultural Policy. Increasing or maintaining soil organic carbon (SOC) content under arable farming has been acknowledged as a primary target of European agricul
