Published: November 2020

A partir de séries longues, sur plus d’un siècle de production de sardine sur les côtes françaises, l’article pose la question du comportement d’adaptation des communautés de pêcheurs face aux variabilités dans l’abondance de la ressource. Une méthode de segmentation de la série chronologique permet d’identifier des points de rupture en recherchant des phases stationnaires. Le résultat aboutit à trois périodes, la première débutant en 1900 avec un point de rupture en 1971. Les deux segments suivants courent sur les périodes 1972 à 1998 et de 1999 à 2017. Le mouvement de concentration de l’industrie de la sardine s’accélère précisément sur le premier point de rupture. Le cadre conceptuel retenu, en complément de la méthode de segmentation, est celui des socio-systèmes et de la résilience des acteurs face à de fortes perturbations. Si les ports de pêche sardiniers ont pu maintenir leur spécialisation par une capacité d’adaptation à des changements mineurs, avant le premier point de rupture, elle devient insuffisante face à des perturbations majeures. La littérature sur les socio-systèmes considère que la capacité d’adaptabilité est alors requise pour maintenir une activité économique. C’est un fait illustré dans cet article.Classification JEL : Q22, N54, C22, L23.
Évaluation du potentiel dual des systèmes technologiques
Authors: Meunier François-Xavier 
Published: November 2020

Durant les dernières décennies le paysage technologique de défense s’est largement ouvert en raison, d’une part, du développement de la dualité technologique et, d’autre part, de la privatisation et de l’internationalisation des entreprises de défense. Ainsi les échanges technologiques entre civil et défense constituent une opportunité pour accélérer l’innovation technologique dans l’un et l’autre de ces domaines. Néanmoins il est difficile d’identifier les systèmes technologiques qui peuvent bénéficier des synergies duales. L’objectif de cet article est de proposer une méthode permettant de mesurer le potentiel dual des systèmes technologiques au niveau mondial pour comparer ces potentiels et identifier les opportunités technologiques.Classification JEL : O32.
L’(in)efficience des universités françaises dans un contexte de forte compétition nationale : une analyse semi-paramétrique

Published: November 2020

Cet article propose d’étudier l’efficience des universités françaises dans leurs missions de formation et de recherche. Ce travail se différencie de la littérature existante par la définition du concept d’efficience, par son champ géographique et par l’hypothèse que le territoire joue un rôle déterminant sur l’efficience des universités. En premier lieu, nous estimons des scores d’efficience des universités françaises via un modèle DEA (Data Envelopment Analysis). Les résultats montrent que le classement d’efficience des universités françaises diverge de ceux établis par un ensemble de classements internationaux controversés. Dans un second temps, à l’aide d’un modèle empirique, nous explorons les facteurs explicatifs de l’efficience des universités françaises. Les résultats montrent que certaines variables territoriales mais aussi un environnement compétitif dans favorisent l’efficience des universités.Classification JEL : H52, I23, O43, R11.

Published: November 2020

Poplars are widely utilized in the intensive and biomass production, as well as in breeding and environment protection programs. This experiment was performed to investigate the effect of drought stress on poplar clones (M-1, PE19/66 and B-229). Poplar clones were grown hydroponically under controlled conditions and exposed to drought stress by applying polyethylene glycol (PEG) 6000. The plant samples were collected and separated into roots and leaves. For estimation of antioxidant status, activities of different antioxidant enzymes were determined (superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (POD), glutathione peroxidase (GPX), glutathione reductase (GR) and ascorbate peroxidase (APX)), as well as antiradical power (ARP) against hydroxyl (˙OH) radical using ESR spin-trapping. The water stress parameters proline (PRO) content, activity of proline dehydrogenase (PDH) and glycine betaine (GB) content were determined. Drought stress had significant effects on PRO and GB contents, SOD, APX and CAT activities when compared to control. All investigated extracts were determined as good inhibitors for ˙OH radical reduction, especially clone M-1where there was an increase of ARP against ˙OH radical in drought condition what could help to prevent or meliorate oxidative damage. Results indicated that the M-1 clone had a greater accumulation of substances for osmotic adjustment and a more efficient enzymatic detoxification cycle for eliminating the negative effects caused by ROS under drought stress than clones B-229 and PE19/66. This study provides valuable information for understanding drought - responsive mechanisms in leaves and roots of poplar clones M-1, B-229 and PE19/66. Key words: antioxidant enzymes, climate change, drought, glycine betaine, proline.

Published: November 2020

This study aimed to investigate the factors that influence the potential user's acceptance of Rocab mobile application for public transportation in Palestine.
This study adopts a quantitative method through 116 electronic questionnaires that developed based on innovation diffusion theory and technology acceptance model. The data were collected based on judgment sampling, which is a purposive sampling technique, meanwhile, partial least squares structural equation modelling (PLS-SEM) analysis was conducted on data elicited from potential users using the Smart-PLS analysis program.
The results showed that 66.3 per cent of the variation in the adoption of Rocab application can be explained by the structural model provided by this research. The results demonstrated that there is a significant effect of relative advantage, compatibility, complexity, and observability on perceived usefulness. The results also showed that the relative advantage, complexity, and observability have a significant effect on perceived ease of use, while compatibility effect on perceived ease of use was found not supported by the collected data. Additionally, perceived usefulness and perceived ease of use were both significantly related to attitude, and, in turn, attitude positively influenced future usage intention to use Rocab application. Overall, it was also found 74.59 per cent of the respondents are willing to use Rocab application in the future.
The originality of this research lies in investigating empirically the factors that influence the potential user's acceptance of Rocab mobile application for public transportation in Palestine which is rare in the literature. This will benefit researchers, the business community as well as policymakers.
Particulate rare earth element behavior in the North Atlantic (GEOVIDE cruise)
Authors: Lagarde Marion , Lemaitre Nolwenn , Planquette Hélène , Grenier Mélanie , Belhadj Moustafa , Lherminier Pascale , Jeandel Catherine 
Published: November 2020

Abstract. Particulate concentrations of the 14 Rare Earth Elements (PREE), yttrium, and 232-thorium were measured in 200 samples collected in the epipelagic (ca. 0–200 m) and mesopelagic (ca. 200–1500 m) zones of the North Atlantic during the GEOVIDE cruise (May/June 2014, R/V
Pourquoi Pas?, GEOTRACES GA01), providing the most detailed snapshot of the
PREE distribution in the North Atlantic so far. Concentrations of
particulate cerium (PCe) varied between 0.2 and 16 pmol L−1, while particulate neodymium (PNd) concentrations ranged between
0.1 and 6.1 pmol L−1. Particulate ytterbium (PYb)
concentrations ranged between 0.01 and 0.50 pmol L−1.
In addition, this study showed that PREE distributions were also controlled
by the biological production in the upper sunlit ocean and by
remineralization processes in the mesopelagic area. Low surface
concentrations combined with normalized PREE patterns displaying a negative
Ce anomaly and HREE enrichments pointed to freshly formed biogenic particles
imprinting the seawater signature. A significant relationship between
biogenic silica (BSi) and PHREE was also observed in the Labrador and
Irminger seas, due to the occurrence of strong diatom blooms at the sampling time. In order to identify dissolved-particulate processes independent of
the ionic radius, we used PHo∕PY ratios and showed that absorption processes
were predominant in the upper ocean, while adsorption processes dominated at deeper depths. This study highlighted different lithogenic fractions of PREE and dispersion depending on the shelf: off the Iberian margin, up to 100 % of the PREE were determined to have a lithogenic origin. This lithogenic input spread
westward along an intermediate nepheloid layer (INL), following isopycnals
up to 1700 km away from the margin. In contrast, along the Greenland and
Newfoundland margins, the circulation maintained lithogenic inputs of PREE
along the coasts.

Abstract. We present a topographic digital elevation model (DEM) for Princess
Elizabeth Land (PEL), East Antarctica. The DEM covers an area of
∼900 000 km2 and was built from radio-echo
sounding data collected during four campaigns since 2015. Previously, to
generate the Bedmap2 topographic product, PEL's bed was characterized from
low-resolution satellite gravity data across an otherwise large
(>200 km wide) data-free zone. We use the mass conservation (MC)
method to produce an ice thickness grid across faster flowing (>30 m yr−1) regions of the ice sheet and streamline diffusion in slower flowing areas. The resulting ice thickness model is integrated with an ice surface model to build the bed DEM. Together with BedMachine
Antarctica and Bedmap2, this new bed DEM completes the first-order
measurement of subglacial continental Antarctica – an international mission that began around 70 years ago. The ice thickness data and bed DEMs of PEL (resolved horizontally at 500 m relative to ice surface elevations obtained from the Reference Elevation Model of Antarctica – REMA) are accessible from https://doi.org/10.5281/zenodo.4023343 (Cui et al., 2020a) and https://doi.org/10.5281/zenodo.4023393 (Cui et al., 2020b).

Abstract. A large-scale field campaign was carried out on the ebb-tidal delta (ETD) of Ameland Inlet, a basin of the Wadden Sea in the Netherlands, as well as on three transects along the Dutch lower shoreface. The data have been obtained over the years 2017–2018. The most intensive campaign at the ETD of Ameland Inlet was in September 2017. With this campaign, as part of KustGenese2.0 (Coastal Genesis 2.0) and SEAWAD, we aim to gain new knowledge on the processes driving sediment transport and benthic species distribution in such a dynamic environment. These new insights will ultimately help the development of optimal strategies to nourish the Dutch coastal zone in order to prevent coastal erosion and keep up with sea level rise.
The dataset obtained from the field campaign consists of (i) single- and multi-beam bathymetry; (ii) pressure, water velocity, wave statistics, turbidity, conductivity, temperature, and bedform morphology on the shoal; (iii) pressure and velocity at six back-barrier locations; (iv) bed composition and macrobenthic species from box cores and vibrocores; (v) discharge measurements through the inlet; (vi) depth and velocity from X-band radar; and (vii) meteorological data. The combination of all these measurements at the same time makes this dataset unique and enables us to investigate the interactions between sediment transport, hydrodynamics, morphology and the benthic ecosystem in more detail. The data provide opportunities to calibrate numerical models to a high level of detail. Furthermore, the open-source datasets can be used for system comparison studies. The data are publicly available at 4TU Centre for Research Data at https://doi.org/10.4121/collection:seawad (Delft University of Technology et al., 2019) and https://doi.org/10.4121/collection:kustgenese2 (Rijkswaterstaat and Deltares, 2019). The datasets are published in netCDF format and follow conventions for CF (Climate and Forecast) metadata.

Abstract. Greenland runoff, from ice mass loss and increasing rainfall, is increasing. That runoff, as discharge, impacts the physical, chemical, and biological properties of the adjacent fjords. However, where and when the discharge occurs is not readily available in an open database. Here we provide data sets of high-resolution Greenland hydrologic outlets, basins, and streams, as well as a daily 1958 through 2019 time series of Greenland liquid water discharge for each outlet. The data include 24 507 ice marginal outlets and upstream basins and 29 635 land coast outlets and upstream basins, derived from the 100 m ArcticDEM and 150 m BedMachine. At each outlet there are daily discharge data for 22 645 d – ice sheet runoff routed subglacially to ice margin outlets and land runoff routed to coast outlets – from two regional climate models (RCMs; MAR and RACMO).
Our sensitivity study of how outlet location changes for every inland cell based on subglacial routing assumptions shows that most inland cells where runoff occurs are not highly sensitive to those routing assumptions, and outflow location does not move far. We compare RCM results with 10 gauges from streams with discharge rates spanning 4 orders of magnitude. Results show that for daily discharge at the individual basin scale the
5 % to 95 % prediction interval between modeled discharge and observations generally falls within plus or minus a factor of 5 (half an order of magnitude, or +500 %/-80 %). Results from this study are available at
https://doi.org/10.22008/promice/freshwater (Mankoff, 2020a) and code is available at http://github.com/mankoff/freshwater (last access: 6 November 2020) (Mankoff, 2020b).
Surface and subsurface characterisation of salt pans expressing polygonal patterns
Authors: Lasser Jana , Nield Joanna M. , Goehring Lucas 
Published: November 2020

Abstract. The data set described here contains information about the surface, subsurface, and environmental conditions of salt pans that express polygonal patterns in their surface salt crust (Lasser et al., 2020b; https://doi.org/10.5880/fidgeo.2020.037). Information stems from 5 field sites at Badwater Basin and 21 field sites at Owens Lake – both in central California. All data were recorded during two field campaigns from between November and December 2016 and in January 2018. Crust surfaces, including the mean diameter and fluctuations in the height of the polygonal patterns, were characterised by a terrestrial laser scanner (TLS). The data contain the resulting three-dimensional point clouds that describe these surfaces. The subsurface is characterised by grain size distributions of samples taken from depths between 5 and 100 cm below the salt crust and measured with a laser particle size analyser. Subsurface salinity profiles were recorded, and the groundwater density was also measured. Additionally, the salts present in the crust and pore water were analysed to determine their composition. To characterise the environmental conditions at Owens Lake, including the differences between nearby crust features, records were made of the temperature and relative humidity during 1 week in November 2016. The field sites are characterised by images showing the general context of each site, such as pictures of selected salt polygons, including any which were sampled, a typical core from each site at which core samples were taken, and close-ups of the salt crust morphology. Finally, two videos of salt crust growth over the course of spring 2018 and reconstructed from time lapse images are included.
Risk assessment in water resources planning under climate change at the Júcar River basin

Published: November 2020

Abstract. Climate change and its possible effects on water resources has become an increasingly near threat. Therefore, the study of these impacts in highly regulated systems and those suffering extreme events is essential to deal with them effectively. This study responds to the need for an effective method to integrate climate change projections into water planning and management analysis in order to guide the decision-making, taking into account drought risk assessments. Therefore, this document presents a general and adaptive methodology based on a modeling chain and correction processes, whose main outcomes are the impacts on future natural inflows, a drought risk indicator, and the simulation of future water storage in the water resources system (WRS). This method was applied in the Júcar River basin (JRB) due to its
complexity and the multiannual drought events it suffers recurrently. The
results showed a worrying decrease in future inflows, as well as a high
probability (≈80 %) of being under 50 % of total capacity of
the WRS in the near future. However, the uncertainty of the results was
considerable from the mid-century onwards, indicating that the skill of climate
projections needs to be improved in order to obtain more reliable results.
Consequently, this paper also highlights the difficulties of developing this
type of method, taking partial decisions to adapt them as far as possible
to the basin in an attempt to obtain clearer conclusions on climate change
impact assessments. Despite the high uncertainty, the results of the JRB call for action and the
tool developed can be considered as a feasible and robust method to
facilitate and support decision-making in complex basins for future water
planning and management.
Technical note: Precipitation-phase partitioning at landscape scales to regional scales

Abstract. Water management throughout the western United States largely relies on the partitioning of cool season mountain precipitation into rain and snow, particularly snow as it maximizes available water for warm season use. Recent studies indicate a shift toward increased precipitation falling as rain, which is consistent with a warming climate. An approach is presented to estimate precipitation-phase partitioning across landscapes from 1948 to the present by combining fine-scale gridded precipitation data with
coarse-scale freezing level and precipitation data from an atmospheric
reanalysis. A marriage of these data sets allows for a new approach to
estimate spatial patterns and trends in precipitation partitioning over
elevational and latitudinal gradients in major water supply basins. This
product is used in California as a diagnostic indicator of changing
precipitation phase across mountain watersheds. Results show the largest
increases in precipitation falling as rain during the past 70 years in
lower elevation watersheds located within the climatological rain–snow
transition regions of northern California during spring. Further development of the indicator can inform adaptive water management strategy development and implementation in the face of a changing climate.
