L’anthropologie phénoménologique de Jan Patočka
Authors: Pesaresi Chiara 
Published: April 2018

La lecture d’une partie de l’œuvre de Patočka que nous proposons dans cet article vise à expliciter les fondements conceptuels de son anthropologie phénoménologique. Par le biais d’une reprise critique des idées hégéliennes de praxis et de négativité, Patočka donne en effet une définition non métaphysique de l’existence humaine. Il s’agit alors de montrer que son interprétation dynamique et dialectique de l’existence s’enracine à la fois dans une réception « hérétique » de la phénoménologie husserlienne et heideggérienne et dans l’héritage – qui reste encore pour la plupart inexploré – de la pensée hégélienne. La critique parallèle de l’idéalisme transcendantal husserlien et de l’idéalisme absolu hégélien ouvre ainsi la voie à une révision du concept d’existence à la lumière de la question fondamentale de la liberté conçue comme transcendance négative.

Published: April 2018

Dans le cadre d’un projet industriel de conception de navettes de transport autonomes (sans chauffeur), notre recherche analyse les expériences vécues et les valeurs en acte des accompagnants afin d’identifier leur contribution à l’acceptation des navettes et du service associé, et de poursuivre la conception de ce service de transport. En effet, à l’étape du développement actuel du projet, le système de transport n’atteint pas le niveau d’autonomie visé et un accompagnant est systématiquement présent à bord de chaque navette. En 2015 et 2016, des investigations ont été menées sur quatre sites sur lesquels les navettes étaient mises à l’essai. Ont alors été réalisés : des analyses systématiques des situations critiques gérées par les accompagnants, et des entretiens composites (semi-directifs inspirés des techniques d’explicitation) auprès de 19 accompagnants. Les résultats montrent que les accompagnants mobilisent 7 valeurs dans leur activité. Quatorze situations critiques impliquant des arbitrages dans des situations où ces valeurs se révèlent contradictoires ont été identifiées. Les réponses apportées en situations révèlent que la hiérarchisation de ces valeurs dépend d’arbitrages variables et situés. Nous discutons ensuite de la contribution de ces réponses à l’acceptation du système de transport, notamment en fiabilisant sa performance, en maximisant son utilité et en développant une relation de service auprès des passagers. Ces résultats conduisent ainsi à interroger le statut de l’humain dans les processus de conception et d’acceptation de technologies autonomes et des services associés.
Measuring business schools’ service quality in an emerging market using an extended SERVQUAL instrument
Authors: Mbise E. R. , Tuninga R. S.J. 
Published: April 2018

An extended SERVQUAL instrument is developed, validated and used to measure perceived service quality delivered to students by business schools in an emerging market economy. A longitudinal survey is conducted with selected students in their final year of study from two business schools in an emerging market economy. The use of the extended SERVQUAL model is suggested to monitor student/employee expectations and perceptions during and after the education service delivery process. Students attach different weights to the service quality dimensions. A new Process Outcome dimension is found to substantially add to the SERVQUAL model and is more important than the other dimensions. The validity of the extended SERVQUAL model for practical use is α >0.95. Prediction of the level of service quality delivered, using four dimensions, indicates that the level of service quality is explained mostly by Process Outcome and Tangibles dimensions. It is suggested that using the extended SERVQUAL model as a tool can enable managers of business schools to identify the factors on which students/employees base their quality assessment of the education services they receive. Knowledge of these factors will enable managers in emerging economies to periodically assess, sustain and improve quality of the whole service delivery process. Priorities can be set to allocate scarce resources properly to make effective investment decisions to improve quality per school and in higher education, in general. The paper further suggests that regulatory bodies make use of this model when comparing performance of business schools, focusing on student experiences as a supplement to the traditional performance measures.
Moderating effects of the relationship between offshore outsourcing and the export capability of firms
Authors: Garcilazo Lagunes S. , Danvila Del Valle I. , Sastre Castillo M. A. 
Published: April 2018

This paper analyzes the effect of offshore outsourcing on the export performance of firms, based on the theories of international business, the resource-based view of the firm and the transaction cost theory.Outsourcing can reduce production costs and increase flexibility. It can also provide new resources and market knowledge. However, the impact of offshore outsourcing depends on the resources and capabilities of firms to manage a network of foreign suppliers, and to absorb knowledge of foreign markets. Using a database of about 1,000 manufacturing companies in Mexico in 2011, we found that offshore outsourcing increases the performance of exports. The effects are stronger in export markets from which the company also imports intermediate goods.The results also show that the size of the company, the organization of intra-firm imports and export experience moderate the effects of outsourcing in a positive way.
The effect of industry nuances on the relationship between corporate governance and financial performance: Evidence from South African listed companies
Authors: Tshipa Jonty , Brummer Leon M. , Wolmarans Hendrik , Du Toit Elda 
Published: April 2018

Background: Premised on agency, resource dependence and stewardship theories, the study investigates empirically the existence of industry nuances in the relationship between corporate governance and financial performance of companies listed in the Johannesburg Stock Exchange. Aims: The main objective of the study is to understand the relationship between internal corporate governance and company performance from the perspective of three distinct economic periods, as well as industry nuances, cognisant of endogeneity issues. Setting: South Africa, as an emerging African market, offers an interesting research context in which the corporate governance and financial performance nexus can be examined empirically. Method: A sample of 90 companies from the five largest South African industries, covering a 13-year period from 2002 to 2014 (1170 firm-year observations) was examined with three estimation approaches. Results: Two key trends emerged from this study. First, the relationship between corporate governance and company performance differed from industry to industry. Second, the association between corporate governance and company performance also changes during steady and non-steady periods, which is an indication that the nexus is driven by the state of the global economy and the type of the industry. Conclusion: Evidence from the study suggests that companies should be allowed to optimise rather than maximise their corporate governance options. This finding questioned the approach of the recently published King IV Code of Good Corporate Governance, which requires Johannesburg Stock Exchange-listed companies to ‘apply and explain’ as opposed to ‘apply or explain’ as pronounced by King III Code of Good Corporate Governance.
A climatology of polar stratospheric cloud composition between 2002 and 2012 based on MIPAS/Envisat observations

Published: April 2018

Abstract. The Michelson Interferometer for Passive Atmospheric
Sounding (MIPAS) instrument aboard the European Space Agency (ESA) Envisat satellite operated from
July 2002 to April 2012. The infrared limb emission measurements provide
a unique dataset of day and night observations of polar stratospheric clouds
(PSCs) up to both poles. A recent classification method for PSC types in infrared (IR)
limb spectra using spectral measurements in different atmospheric window
regions has been applied to the complete mission period of MIPAS. The method
uses a simple probabilistic classifier based on Bayes' theorem with a strong
independence assumption on a combination of a well-established two-colour
ratio method and multiple 2-D probability density functions of brightness
temperature differences. The Bayesian classifier distinguishes between solid
particles of ice, nitric acid trihydrate (NAT), and liquid droplets of
supercooled ternary solution (STS), as well as mixed types. A climatology of MIPAS PSC occurrence and specific PSC classes has been
compiled. Comparisons with results from the classification scheme of the
spaceborne lidar Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP)
on the Cloud-Aerosol-Lidar and Infrared Pathfinder Satellite Observations
(CALIPSO) satellite show excellent correspondence in the spatial and
temporal evolution for the area of PSC coverage (APSC) even for each
PSC class. Probability density functions of the PSC temperature, retrieved
for each class with respect to equilibrium temperature of ice and based on
coincident temperatures from meteorological reanalyses, are in accordance
with the microphysical knowledge of the formation processes with respect to
temperature for all three PSC types. This paper represents unprecedented pole-covering day- and nighttime
climatology of the PSC distributions and their composition of different
particle types. The dataset allows analyses on the temporal and spatial
development of the PSC formation process over multiple winters. At first
view, a more general comparison of APSC and AICE retrieved from
the observations and from the existence temperature for NAT and ice
particles based on the European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis temperature data shows the high potential
of the climatology for the validation and improvement of PSC schemes in
chemical transport and chemistry–climate models.
The influence of internal variability on Earth's energy balance framework and implications for estimating climate sensitivity
Authors: Dessler Andrew E. , Mauritsen Thorsten , Stevens Bjorn 
Published: April 2018

Abstract. Our climate is constrained by the balance between solar energy absorbed by the Earth and terrestrial energy radiated to
space. This energy balance has been widely used to infer equilibrium climate sensitivity (ECS) from observations of
20th-century warming. Such estimates yield lower values than other methods, and these have been influential in pushing down
the consensus ECS range in recent assessments. Here we test the method using a 100-member ensemble of the Max Planck Institute Earth System Model
(MPI-ESM1.1) simulations of the period 1850–2005 with known forcing. We calculate ECS in each ensemble member using
energy balance, yielding values ranging from 2.1 to 3.9 K. The spread in the ensemble is related to the central
assumption in the energy budget framework: that global average surface temperature anomalies are indicative of anomalies
in outgoing energy (either of terrestrial origin or reflected solar energy). We find that
this assumption is not well supported
over the historical temperature record in the model ensemble or more recent satellite observations. We find that framing
energy balance in terms of 500 hPa tropical temperature better describes the planet's energy balance.
Automated enclosure and protection system for compact solar-tracking spectrometers
Authors: Heinle Ludwig , Chen Jia 
Published: April 2018

Abstract. A novel automated enclosure for protecting solar-tracking atmospheric instruments was designed, constructed, and successfully tested under various weather conditions. A complete automated measurement system, consisting of a compact solar-tracking Fourier transform infrared (FTIR) spectrometer (EM27/SUN) and the enclosure, has been deployed in central Munich to monitor greenhouse gases since 2016 and withstood all critical weather conditions, including rain, storms, and snow. It provided ground-based measurements of column-averaged concentrations of CO2, CH4, O2, and H2O throughout this time.The enclosure protects the instrument from harmful environmental influences while allowing open-path measurements in sunny weather. The newly developed and patented cover, a key component of the enclosure, permits unblocked solar measurements while reliably protecting the instrument. This enables dynamic decision regarding taking measurements, and thus increases the number of data samples. This enclosure leads to a fully automated measurement system, which collects data whenever possible without any human interaction. In the long term, the enclosure will provide the foundation for a permanent greenhouse gas monitoring sensor network.
QUAL-NET, a high temporal-resolution eutrophication model for large hydrographic networks
Authors: Minaudo Camille , Curie Florence , Jullian Yann , Gassama Nathalie , Moatar Florentina 
Published: April 2018

Abstract. To allow climate change impact assessment of water quality in river systems, the scientific community lacks efficient deterministic models able to simulate hydrological and biogeochemical processes in drainage networks at the regional scale, with high temporal resolution and water temperature explicitly determined. The model QUALity-NETwork (QUAL-NET) was developed and tested on the Middle Loire River Corridor, a sub-catchment of the Loire River in France, prone to eutrophication. Hourly variations computed efficiently by the model helped disentangle the complex interactions existing between hydrological and biological processes across different timescales. Phosphorus (P) availability was the most constraining factor for phytoplankton development in the Loire River, but simulating bacterial dynamics in QUAL-NET surprisingly evidenced large amounts of organic matter recycled within the water column through the microbial loop, which delivered significant fluxes of available P and enhanced phytoplankton growth. This explained why severe blooms still occur in the Loire River despite large P input reductions since 1990. QUAL-NET could be used to study past evolutions or predict future trajectories under climate change and land use scenarios.
The Global Streamflow Indices and Metadata Archive (GSIM) – Part 2: Quality control, time-series indices and homogeneity assessment
Authors: Gudmundsson Lukas , Do Hong Xuan , Leonard Michael , Westra Seth 
Published: April 2018

Abstract. This is Part 2 of a two-paper series presenting the Global Streamflow Indices
and Metadata Archive (GSIM), which is a collection of daily streamflow
observations at more than 30 000 stations around the world. While Part 1 (Do
et al., 2018a) describes the data collection process as well as the
generation of auxiliary catchment data (e.g. catchment boundary, land cover,
mean climate), Part 2 introduces a set of quality controlled time-series
indices representing (i) the water balance, (ii) the seasonal cycle,
(iii) low flows and (iv) floods. To this end we first consider the quality of
individual daily records using a combination of quality flags from data
providers and automated screening methods. Subsequently, streamflow
time-series indices are computed for yearly, seasonal and monthly resolution.
The paper provides a generalized assessment of the homogeneity of all
generated streamflow time-series indices, which can be used to select time
series that are suitable for a specific task. The newly generated global set
of streamflow time-series indices is made freely available with an digital
object identifier at https://doi.pangaea.de/10.1594/PANGAEA.887470 and
is expected to foster global freshwater research, by acting as a ground truth
for model validation or as a basis for assessing the role of human impacts on
the terrestrial water cycle. It is hoped that a renewed interest in
streamflow data at the global scale will foster efforts in the systematic
assessment of data quality and provide momentum to overcome administrative
barriers that lead to inconsistencies in global collections of relevant
hydrological observations.
Identification of stable areas in unreferenced laser scans for automated geomorphometric monitoring
Authors: Wujanz Daniel , Avian Michael , Krueger Daniel , Neitzel Frank 
Published: April 2018

Abstract. Current research questions in the field of geomorphology focus on the impact
of climate change on several processes subsequently causing natural hazards.
Geodetic deformation measurements are a suitable tool to document such
geomorphic mechanisms, e.g. by capturing a region of interest with
terrestrial laser scanners which results in a so-called 3-D point cloud. The
main problem in deformation monitoring is the transformation of 3-D point
clouds captured at different points in time (epochs) into a stable reference
coordinate system. In this contribution, a surface-based registration
methodology is applied, termed the iterative closest proximity algorithm
(ICProx), that solely uses point cloud data as input, similar to the
iterative closest point algorithm (ICP). The aim of this study is to
automatically classify deformations that occurred at a rock glacier and an
ice glacier, as well as in a rockfall area. For every case study, two epochs
were processed, while the datasets notably differ in terms of geometric
characteristics, distribution and magnitude of deformation. In summary, the
ICProx algorithm's classification accuracy is 70 % on average in
comparison to reference data.
The sedimentological changes caused by human impact at the artificial channel of Medjerda-River (Coastal zone of Medjerda, Tunisia)

Published: April 2018

Abstract. Recent sedimentary and morphological changes at the new mouth of
Medjerda-River (Gulf of Tunis) are investigated using a multiproxy approach
of sediment cores complited by 210Pbex and 137Cs method dating. The
subject of the study is to focus on surveying the sedimentary evolution of
Medjerda-Raoued Delta caused by the human intervention in the management of
the main tributaries of the Medjerda-River (artificial channel of Henchir
Tobias). Sediment cores (CEM-1 and CEM-3) were subjected to both multiproxy
approaches (Grain size, geochemical analysis and dating radiometric
210Pbex and 137Cs). The sedimentological analysis of the new
deltaic deposits shows a progradation sequence with the silt and clay
deposits on the historic sandy substratum. The mean grain size evolution on
the old beach profile shows a decreasing trend from backshore (CEM-3) to
nearshore (CEM-1). The geochemical results show varying concentrations of
chemical elements such as Fe, K, Rb, Nb, Cr, Ti, Ba, Ca, Sr, Zr, V, and
potentially toxic metal trace elements such as Pb, Zn and the As. The
Principal component Analysis (PCA) applied in the geochemical elements
evolution confirms the marine origin of the sand deposits in the basic layers
of the two cores. The chronological method (210Pbex and 137Cs)
affirms that the first fluvial deposits were set up only after 1950. The
sedimentological and geochemical result confirm the actual unless of coarser
fluvial supplies under the human activities leading the negative coastal
sediment balance and the shoreline retreat as well.

Published: April 2018

Óleos de andiroba, copaíba e pinhão-manso são estudados por serem empregados em fins variados, como sabões, velas, medicamentos, biodiesel, tintas, fiação de lã e lustração de móveis. Também, são utilizados como inseticidas, fungicidas e moluscicidas. Objetivou-se neste trabalho caracterizar as propriedades físicas dos óleos de andiroba, copaíba e pinhão-manso, puros ou enriquecidos com iodo sublimado (I2) e avaliar sua eficiência contra fungos de podridão parda e branca. Os óleos de andiroba e copaíba foram oriundos de comunidades do município de Santarém (PA) e o óleo de pinhão-manso, da Fazenda Tamanduá, município de Santa Terezinha (PB). Foram determinadas as características físicas (pH, índice de acidez, viscosidade e densidade) dos óleos e realizado o ensaio de toxidez em meio de cultura com fungos de podridão parda e branca. O enriquecimento dos óleos com iodo (I2) proporcionou aumento da viscosidade. Foi constatada menor densidade para o óleo puro de andiroba e copaíba do que para o enriquecido com 5% de I2. O incremento de iodo nas soluções propiciou a diminuição de pH nos óleos de andiroba e copaíba, além do aumento do índice de acidez do óleo de andiroba. Para a avaliação da eficiência, os óleos foram empregados puros ou enriquecidos com iodo sublimado. No ensaio de toxidez em meio de cultura, para o fungo Trametes versicolor, a maior inibição em 20 dias foi para o tratamento com andiroba 1% de I2. Para o fungo Postia placenta, a maior inibição foi constatada para o tratamento com óleo de andiroba com 5% de I2.

Published: April 2018

O objetivo deste trabalho foi aplicar e avaliar o desempenho de métodos de amostragem de área variável em regeneração natural da espécie candeia em áreas submetidas ao sistema de manejo com porta sementes. Os dados foram coletados em 46 Unidades de Estudos com regeneração natural da espécie. Foram simuladas variações estruturais dos métodos de amostragem de Strand e Prodan para estimar o número de plantas por hectare e a altura média. Os valores estimados foram comparados com o valor de referência por meio de regressão, do coeficiente de correlação Pearson e do índice de concordância de Willmott. O desempenho foi avaliado pela associação da correlação de Pearson com o índice de Willmott. O teste não paramétrico de Kruskal-Wallis foi aplicado para verificar diferenças estatísticas entre as médias estimadas e a referencial. O método de Strand com linhas de 4 e 5 m foi preciso e exato na estimativa da densidade e da altura média. O método de Prodan superestimou a densidade, mas foi preciso para estimar a altura média. Conclui-se que o método de amostragem de Strand, utilizando linha de 4 m de comprimento, pode ser utilizado para amostrar a regeneração natural da espécie candeia, que apresenta padrão espacial agregado.
