Skill-Based Scouting of Open Management Content
2010
Already existing open educational resources in management have a high potential for enterprises to address the increasing training needs of their employees. However, access barriers still prevent the full exploitation of this potential. Users have to search a number of repositories with heterogeneous interfaces in order to retrieve the desired content. In addition, the use of search criteria related to skills, such as learning objectives and skill-levels is in most cases not supported. The demonstrator presented in this paper addresses these shortcomings by federating multiple repositories, integrating and enriching their metadata, and employing skill-based search for management related con…
Some Implications for Developing Learners’ Figurative Language Competence Across Modalities: Metaphor, Metonymy and Blending in the Picture Modality
2014
The paper argues for developing learners’ figurative language competence across modalities. Specifically, focusing on the picture modality, the article attempts to show the importance of figurative thinking in the new media age multimodal communication. The sample analysis of pictures and images representing the recent issue of the EU crisis addresses the significance of three conceptual phenomena, namely, metaphor, metonymy, and blending, in the conceptualization of such a highly abstract phenomenon. In general, it is argued that language users almost invariably turn to figurative language resources to conceptualize abstract phenomena that cannot be conceptualized by means of literal langu…
Platform GenoSol: a new tool for conserving and exploring soil microbial diversity
2009
International audience; Soils are the principal reservoirs of microbial diversity and represent a core component of terrestrial ecosystems. There is an increasing demand for assessing the impact of agricultural and industrial practices on the environment at large scales in a context of global change. To address this demand, taxonomic and functional diversity of soil microbial communities, and their stability over time need to be characterized for predicting soil quality upon human activities, the evolution of this quality being expected to affect environment quality and public health. Recent methodological progresses have led to the development and automation of molecular biological tools (…
The role of public biological resource centers in providing a basic infrastructure for microbial research
2009
Public collections of microorganisms have been established since the late 19th century, and currently 573 service collections are registered at the World Data Center for Microorganisms (www.wdcm.org). All together, they hold more than 1.5 million microorganisms. By implementing guidelines compiled by the Organisation for Economic Co-operation and Development (OECD), many public service collections evolve into professional ex situ repositories of biodiversity and distribution nodes for known, validated and precisely identified microbial resources and associated information to legitimate end-users. These Biological Resource Centers (BRCs) may be the preferred mechanism for the appropriate exp…
Perspectives on the Impact of Sampling Design and Intensity on Soil Microbial Diversity Estimates
2019
Soil bacterial communities have long been recognized as important ecosystem components, and have been the focus of many local and regional studies. However, there is a lack of data at large spatial scales, on the biodiversity of soil microorganisms; national or more extensive studies to date have typically consisted of low replication of haphazardly collected samples. This has led to large spatial gaps in soil microbial biodiversity data. Using a pre-existing dataset of bacterial community composition across a 16-km regular sampling grid in France, we show that the number of detected OTUs changes little under different sampling designs (grid, random, or representative), but increases with t…
Genetic islands in pome fruit pathogenic and non-pathogenic Erwinia species and related plasmids
2015
New pathogenic bacteria species belonging to the genus Erwinia associated with pome fruit trees (Erwinia pyrifoliae, E. piriflorinigrans, E. uzenensis) have been increasingly described in the last years, and comparative analyses have found that all these species share several genetic characteristics. Studies at different level (whole genome comparison, virulence genes, plasmid content, etc.) show a high intraspecies homogeneity (i.e. among E. amylovora strains) and also abundant similarities appear between the different Erwinia species: presence of plasmids of similar size in the pathogenic species; high similarity in several genes associated with exopolysaccharide production and hence, wit…
Wine Yeast Terroir: Separating the Wheat from the Chaff-for an Open Debate.
2020
Wine terroir is characterized by a specific taste and style influenced by the cultivar of the fermented grapes, geographical factors such as the vineyard, mesoclimate, topoclimate, and microclimate, soil geology and pedology, and the agronomic approach used. These characteristics together define the concept of “terroir”. Thus, regional distinctive flavors in wine have been the subject of many studies aimed at better understanding the link between the wine and the vineyard. Indeed, the identification of key environmental elements involved in the regional variation of grape and wine quality characteristics is a critical feature for improving wine production in terms of consumer preference and…
Validación y verificación analítica de los métodos microbiológicos
2015
Clinical microbiologists should ensure, to the maximum level allowed by the scientific and technical development, the reliability of the results. This implies that, in addition to meeting the technical criteria to ensure their validity, they must be performed with a number of conditions that allows comparable results to be obtained, regardless of the laboratory that performs the test. In this sense, the use of recognized and accepted reference methodsis the most effective tool for these guarantees. The activities related to verification and validation of analytical methods has become very important, as there is continuous development, as well as updating techniques and increasingly complex …
Strategic Behavior and Efficiency in the Common Property Extraction of Groundwater
2002
Groundwater has always been regarded as a common property resource where entry is restricted by land ownership and private exploitation is inefficient. In 1980, Gisser and Sanchez presented a first estimation of this inefficiency, cornparing socially optimal exploitation with private (competitive) exploitation using a model with linear water demand, average extraction cost independent of the rate of extraction and linearly decreasing with respect to the water table level. They characterized the private exploitation of the aquifer assuming that farmers are myopic and choose their rate of extraction to maximize their current profits, whereas optimal exploitation is obtained by maximizing the …
Adjustment costs, uncertainty, and the theory of investment: the case of non-renewable natural resources
1992
Abstract This paper examines the effects of mineral price and extraction cost uncertainty on the investment program of a competitive resource-extracting industry that faces convex costs of adjustment. The results show that depletion of mineral reserves will slow down if the marginal adjustment cost function is concave or linear, whereas the effect will be ambiguous if the function is convex.
