Subject:
imports,   etc   ; energy; fuels; politics; Europe;     Show all 5 Subjects
Abstract:
... Studies of energy and geopolitics have been almost totally monopolized by analyses of the largest and most powerful countries in the world. This article argues that it is crucial to include the world's smaller and less powerful nations, too, into the analysis. Adopting a systems perspective, the article discusses Europe's smaller nations that have come to depend on other countries for various acti ...

Abstract:
... Consumption of local food is a fast-growing trend supported by local food advocates and governments. This trend has also captured the interest of researchers. The present study draws from the foundational principles of the theoretical perspective of helping behaviour with a view to enhancing the understanding of why people buy local food. This article tests a conceptual framework with proposed rel ...

Abstract:
... The aim of this article is to examine the shifting strategies towards the dependence on imported energy which has originated from the lack of energy resources in Denmark. The article suggests that the international economic conditions strongly influenced the energy strategies chosen in the 1950s and 1960s. In the 1970s and onwards, the dependence was dealt with as a combination of diversification ...

In the present study, an advanced and original multivariate strategy for the processing of hyperspectral images in the near-infrared region is proposed to automatically detect physico-chemical defects in green coffee, which are similar one to each other by naked eye. An object-based approach for the characterization of individual beans, rather than single pixels, was adopted, calculating a series ...

Abstract:
... The fluctuations of international crude oil markets have caused significant attention around the world and aroused strong interest in the forecasting of the systemic risk in crude oil trade. Based on the oil imported values data of 34 major oil-importing countries from January 2005 to June 2017, we calculate the cross-correlation functions of time lags and construct a sequence of time-evolving oil ...

Abstract:
... Plants possess both types of endosymbiotic organelles, chloroplasts and mitochondria. Transit peptides and presequences function as signal sequences for specific import into chloroplasts and mitochondria, respectively. However, how these highly similar signal sequences confer this import specificity remains elusive. Here, we show that mitochondrial- or chloroplast-specific import involves two dist ...

Abstract:
... In 1900 a Swedish member of parliament argued that Sweden had a Damocles Sword hanging over it due to the country's rapidly growing imports of coal. This energy import dependence has continued to plague Sweden ever since. While coal dominated imports in the first half of the twentieth century, oil and uranium dominated in the second half. This article examines how Swedish public and private actors ...

Abstract:
... Using Italian matched employer–employeedata, I examine how accounting for unobserved worker or firm heterogeneity can impact estimates of import competition’s impact on industry-level gender wage gaps, and how this can be driven by changes in the composition of female workers and firms within affected industries. First, in wage regressions, I find that import competition lowers women’s wages relat ...

Abstract:
... The European Union (EU) is responsible for a disproportionately large share of global environmental footprints, in particular those embodied in trade through its imports. Import embodied footprints (IEFs) vary significantly depending on the country of origin, and therefore can be reduced through source shifting. We explore the impacts of shifting imports to the countries with lowest impact intensi ...
