Unraveling the exhumation history of high-pressure ophiolites using magnetite (U-Th-Sm)/He thermochronometry
2020
International audience; Magnetite is a ubiquitous oxide in ultramafic and mafic rocks, which is present in a large range of geological and tectonic settings. In the case of high-pressure ultramafic rocks, exhumation timing is commonly constrained by geochronometers in nearby lithologies. The development of the magnetite (U-Th-Sm)/He method (MgHe) has opened new perspectives to refine the exhumation history of such rocks. However no thermal history has been deduced using MgHe data so far. Here we applied MgHe dating to magnetite from an HP-LT alpine ophiolite body (Rocher Blanc) from the Schistes lustres units (Western Alps, France) where part the P-T-t history is constrained to further refi…
Banach spaces where convex combinations of relatively weakly open subsets of the unit ball are relatively weakly open
2018
We introduce and study Banach spaces which have property CWO, i.e., every finite convex combination of relatively weakly open subsets of their unit ball is open in the relative weak topology of the unit ball. Stability results of such spaces are established, and we introduce and discuss a geometric condition---property (co)---on a Banach space. Property (co) essentially says that the operation of taking convex combinations of elements of the unit ball is, in a sense, an open map. We show that if a finite dimensional Banach space $X$ has property (co), then for any scattered locally compact Hausdorff space $K$, the space $C_0(K,X)$ of continuous $X$-valued functions vanishing at infinity has…
UDP-glucose deficiency in a mutant cell line protects against glucosyltransferase toxins from Clostridium difficile and Clostridium sordellii.
1996
Abstract We have previously isolated a fibroblast mutant cell with high resistance to the two Rho-modifying glucosyltransferase toxins A and B of Clostridium difficile. We demonstrate here a low level of UDP-glucose in the mutant, which explains its toxin resistance since: (i) to obtain a detectable toxin B-mediated Rho modification in lysates of mutant cells, addition of UDP-glucose was required, and it promoted the Rho modification dose-dependently; (ii) high pressure liquid chromatography analysis of nucleotide extracts of cells indicated that the level of UDP-glucose in the mutant (0.8 nmol/106 cells) was lower than in the wild type (3.7 nmol/106 cells); and (iii) sensitivity to toxin B…
Life of a Fatso : Young, Fat and Vulnerable in a Scandinavian Society of Perfection
2020
This chapter offers a close reading of the young adult novel Miss by Synne Sun Loes (2017). The story is about 16-year-old Ea who is at the point of dropping out of school. The title carries a double reference—on the one hand, to Ea’s feeling of being a mis(s)fit and, on the other hand, to her critique of her best friend turning into a ‘Little Miss Perfect’. The analysis discusses two main questions: What has made this teenager from a well-off family so vulnerable? and How is her resistance expressed? The analysis explores how Ea positions herself as an outsider through bodily and social protest, making her both vulnerable and strong, and discusses this in relation to Judith Butler’s (2016)…
Lifelong education
2016
In a society where population aging is a very present reality, it is urgent the adaptation of social policies and strategies for promoting the well-being of this age group [7]. Learning lifelong and adult education are strategies that aim to achieve social, cultural and economic development [4]. They are, undoubtedly, strategies that have a positive impact on society. Intergenerational learning is a practice that allows us to include not only the older, as far as the younger population, benefiting from this strategy two disparate generations. Learning throughout life, through intergenerational sociability, has added value, encourages the closeness between the generations: the younger ones, …
Co‐parenting through subsidiaries: A model of value creation in the multinational firm
2017
Research summary We analyze a novel way to configure and manage multinational networks and propose a model of "co-parenting", characterized by the sharing of parenting roles and distribution of responsibilities between two units. We develop our argument around the notion of the springboard subsidiary, an operating subsidiary which assumes headquarters’ functions since it shares greater institutional closeness with both the headquarters’ country as well as with the host region. Based upon qualitative data, our inductive model revolves around three stages: establishment, consolidation and maturity, each of which reflects distinct roles and loci of decision making among the three actors involv…
Molecular analysis suggests that recent Citrus tristeza virus outbreaks in Italy were originated by at least two independent introductions
2005
Citrus tristeza virus (CTV) is the causal agent of the most important virus disease of citrus. Numerous CTV isolates differing in biological and molecular characteristics have been reported worldwide. Recently, CTV was detected in Italy in several citrus crops from three separate areas: (1) Cassibile, province of Syracuse; (2) Massafra, province of Taranto; and (3) Belpasso, province of Catania. CTV isolates from Massafra and Cassibile were mild, whereas isolates from Belpasso induced severe symptoms. To study the genetic variation of CTV populations of these areas, 150 samples per area were examined by single strand conformation polymorphism (SSCP) and nucleotide sequence analysis of CTV g…
Violence in close relationships and the dramaturgy of violence
2012
The assumption, at the basis of the report, considers the bullying - inside the systemic approach - as a state of oppression caused by the identitary uncertainty of many teenagers. Today, the violence between peers is characterized as one of the most effective strategies for the construction of atypical identity or troubled identities, in specific relational contexts (frames). The mutual acceptance and the permanence in the deviant group, allows the creation/attribution of an identity to each member of the group, and it is subject to the so-called "cognitive responsibility", which allows the voluntary perpetuation (replication) of a "dramatic scene" (framework).This last takes the form of a…
Market Determinants of Voluntary Disclosure of Macroeconomic Effects on Corporate Performance
2012
The macroeconomic environment is an important determinant of firm performance. Nevertheless, many firms are simplistic in the approach they use to identify, analyze and create strategies for managing the vital relationship between intrinsic competitiveness and macroeconomic fluctuations. Few firms disclose this information to outside stakeholders, which means they are prevented from understanding the intrinsic performance. We analyze the effects of the implementation/development of IFRS/IAS 1 on voluntary macroeconomic information disclosure with a focus on information content and market determinants. We base our analysis on a sample of the 100 largest public European firms in the period 20…
Determinants of internet‐based corporate governance disclosure by Spanish listed companies
2008
PurposeThe purpose of this paper is to analyse the corporate governance information disclosed by Spanish listed companies on the internet, with the objective of assessing the extent and the influence of several corporate characteristics on the level of information voluntarily disclosed.Design/methodology/approachThe study took as its reference the existing literature on the examination of the quality of web sites and the importance of content as a key variable in determining web site quality. To quantify the corporate governance information disclosed by Spanish listed companies, three transparency indexes were designed. To contrast which variables determine the information provided online, …
