Perspectives et bilan après 20 ans de recherche au bas de la pyramide, une étude bibliométrique pour le futur du management international

2021

Cet article propose une analyse bibliométrique du champ des stratégies au bas de la pyramide (BoP) fondée sur 364 articles citants issus de la plateforme Web of Science fournissant une base de 15 292 références. Différents outils sont mobilisés, pour mettre en évidence la structure du champ BoP d’une part, et pour identifier les tendances du front de recherche d’autre part. Six groupes structurant le champ émergent des analyses, chacun mettant en évidence un courant de recherche, et cinq tendances rythment les recherches actuelles sur le BoP. Ces analyses permettent de proposer quatre perspectives pour le futur du management international.

Economic Theorizing, Discursive Analysis and Pluralism in the Classroom - Evidence from Postgraduate Teaching in a French University

2014

Can students examine the discursive strategies employed by economists so that the former think critically about the underlying theoretical forces described by the latter? Are economic processes ontologically dependent on the narratives used by economists to account for real phenomena? In this article, we draw both on Wheat's mapping techniques to homogenise theoretical economic discourse and on Pilkington's attempt to combine economics with language for specific purposes. We show that informed and fruitful discussions in the classroom necessitate the use of a new median pluralistic discourse that is yet to be elaborated upon, both by university and secondary school teachers. Finally, in ord…

SENTINEL-1 for wheat mapping and soil moisture retrieval

2015

The main objective of this study is to assess the use of Sentinel-1 (S-1) data for surface soil moisture (SSM) retrieval and wheat mapping (WM) at high spatial resolution (e.g. 100–500m), which constitute valuable information for improving crop yield forecast at large scale. A knowledge based classification method and a SSM retrieval algorithm, developed in view of the European Space Agency Sentinel-1 mission, have been applied to a time series of S-1A data collected from October 2014 to April 2015 over a well-documented agricultural site in southern Italy. In particular, observations of SSM content recorded by a network of ground stations deployed in an experimental farm have been used to …

Digital Soil Mapping in the Irish Soil Information System

2009

Harmonised soil data across Europe with a 1:250 000 geo-referenced soil database will allow for exchange of data across member states and the provide the information needed by the European Commission and European Environment Agency for reporting on issues relating to soil quality under a fu-ture Soil Framework Directive. Within this context, the Environmental Protection Agency of the Republic of Ireland commissioned a project run by Teagasc to produce a 1:250 000 soil map of the Republic of Ire-land. Delivery of this map and associated database is a collaborative effort between Teagasc, the National Soil Resources Institute at Cranfield in the UK and University College Dublin. Environmental…

4D paleoenvironmental evolution of the Early Triassic Sonoma Foreland Basin (western USA)

2017

In the wake of the Mesozoic, the Early Triassic (~251.95 Ma) corresponds to the aftermath of the most severe mass extinction of the Phanerozoic: the end-Permian crisis, when life was nearly obliterated (e.g., 90% of marine species disappeared). Consequences of this mass extinction are thought to have prevailed for several millions of years, implying a delayed recovery lasting the whole Early Triassic, if not more. Several paradigms have been established and associated to a delayed biotic recovery scenario expected to have resulted from harsh and deleterious paleoenvironments. These paradigms include a global anoxia in the marine realm, a “Lilliput” effect, and the presence of “disaster” tax…

Source localization of event-related potentials to pitch change mapped onto age-appropriate MRIs at 6 months-of-age

2010

Auditory event-related potentials (ERPs) have been used to understand how the brain processes auditory input, and to track developmental change in sensory systems. Localizing ERP generators can provide invaluable insights into how and where auditory information is processed. However, age-appropriate infant brain templates have not been available to aid such developmental mapping. In this study, auditory change detection responses of brain ERPs were examined in 6-month-old infants using discrete and distributed source localization methods mapped onto age-appropriate magnetic resonance images. Infants received a passive oddball paradigm using fast-rate non-linguistic auditory stimuli (tone do…

Spatial representations of the future in Homeric Greek

The aim of this paper is to investigate the space-time mapping of the future in Homeric Greek. It is widely accepted that the spatial adverbs πρόσσω ‘in front’ and ὀπίσσω ‘behind’ in the Homeric poems are used to portray temporal events located in a sequence of aligned entities that follow one after the other on the same path (Dunkel 1983: 66). In such a temporal sequence, or Time-RP model, those adverbs are associated respectively to past and future events in a dichotomous spatial representation of time, without involving a deictic ego-experiencer. After analyzing data from the Homeric poems in a cognitive linguistic perspective, it is found that some temporal uses of the preposition πρό ‘…

Detection and localisation of disulphide bonds in a synthetic peptide reproducing the sequence 1-30 of Par j 1.0101 by electrospray ionisation mass s…

2001

The structural characterisation of a synthetic peptide reproducing the sequence 1–30 of Par j 1.0101, a major allergenic protein present in the pollen of Parietaria judaica, by combined use of chemical and enzymatic cleavage, reversed-phase high-performance liquid chromatography (RP-HPLC) and electrospray ionisation mass spectrometry (ESI-MS), is described. Direct ESI-MS of the synthetic peptide after reaction with methyl iodide showed that the product is a mixture of two peptides: one form in which two out of the four cysteine residues present in the sequence are oxidised and a minor amount of another form in which all the cysteines are fully reduced. It was ascertained, using the combined…

Direct infusion mass spectrometry as a fingerprint of protein-binding media used in works of art

2005

A direct infusion mass spectrometry method for the characterization of proteinaceous glues from binding media used in pictorial works of art prior to conservation or restoration treatment is proposed. Amino acids are released by acid hydrolysis and dissolved in a mixture of acidic water and ethanol. This mixture is directly infused into a mass spectrometer without any derivatization. The mass spectrometer is operated in positive ion electrospray mode (ESI-MS) to yield [M+H]+ ions for the amino acids. Relative amounts of each amino acid are calculated for each protein (beef and porcine gelatines, albumin, casein and egg). The analyzed proteins were satisfactorily distinguished. The method is…
