Formal subdivision of the Cambrian System into four series and ten stages is in progress. The base of Cambrian Stage 3 (provisional), which is conterminous with the base of Cambrian Series 2 (provisional), is expected to be placed at a horizon close to the first appearance of trilobites, which marks the onset of the largest phase of the Cambrian explosion. Conceptually, an ideal boundary position

Among all the different ways used by the social State to promote higher labour standards the public procurements have always played an important role. Exploiting them economic attractiveness, in fact, most Countries used to insert in them several types of social clauses, so to oblige the awarded tenderer to grant a broad series of rights to the employees involved in the execution of the procuremen

In a solid-state host, attractive electron-electron interactions can lead to the formation of local electron pairs which play an important role in the understanding of prominent phenomena such as high T c superconductivity and the pseudogap phase. Recently, evidence of a paired ground state without superconductivity was demonstrated at the level of single electrons in quantum dots at the interface

his paper investigates regional business cycle co-movements in Austria–Hungary from 1867 to 1913. Economic theory suggests that rising market integration induces sectoral specialisation, resulting in a reduction in the correlation of regional GDP cycles (Krugman effect). However, the synchronisation of business cycles is expected to increase because of the growing inter-linkages among regions led

The paper examines empirically the effect of international trade and geographic proximity on knowledge inflow to Sweden. Swedish patent data is used to trace knowledge flows. Both geographic proximity and international trade are in a first estimation found to affect knowledge flows. An extreme bounds analysis is conducted on the estimated coefficients. The coefficient for geographic proximity is s

During the decades after World War II, countries began shifting taxation from income to consumption. This shift has been associated with an expanding welfare state and left-wing dominance. However, the pattern is far from uniform and while some left-wing governments indeed expanded consumption taxation, others did not. This paper seeks to explain why, by exploring how experts influenced post-war t

Living labs as a research approach have been said to hold many promises regarding the evaluation of state-of-the art technologies in real-world contexts, for instance by allowing close cooperation with various stakeholders. At the same time, a living lab approach is connected with substantial complexity and increased risk. This paper elaborates on a conducted living lab with the objective to explo

Objective: Meal ingestion is followed by a redistribution of blood flow (BF) within the splanchnic region contributing to nutrient absorption, insulin secretion and glucose disposal, but factors regulating this phenomenon in humans are poorly known. The aim of the present study was to evaluate the organ-specific changes in BF during a mixed-meal and incretin infusions. Design: A non-randomized int

The neurodevelopmental hypothesis of schizophrenia has become a paradigm broadly accepted in today's research in schizophrenia and its spectrum. This article traces the historical development of the neurodevelopmental hypothesis of schizophrenia up until the time of its explicit formulation in 1987, by Weinberger and by Murray and Lewis, with a main focus on the seminal contribution of Barbara Fis

Ethnographic (and other) studies on teachers often rely on two kinds of material: observations of teaching practices in the classroom; and statements about teaching practices, extracted both from involved actors (e.g. teacher interviews) and from documents (e.g. educational policy documents or teaching manuals). Many scholars agree that there is a discrepancy between what is stated, or desired, pr

We analyze the effects of the increase in China’s import competition on Mexican domestic and international migration. We exploit the variation in exposure to competition from China, following its accession to the WTO in 2001, across Mexican municipalities and estimate the effect of international competition on the individual decision to migrate. Controlling for individual and municipality features
