The iPhone and its antecedents: re-thinking entry and the evolution of platform strategies at Apple Inc.
Authors: Glimstedt Henrik
Published: May 2020

Les universitaires considèrent l’entrée réussie d’Apple sur le marché de la musique et des smartphones comme le moment charnière dans le développement stratégique, organisationnel et financier de l’entreprise qui en a fait le leader incontesté dans le domaine des plates-formes. Mais on sait peu de choses de la construction, de la dynamique et de l’évolution de l’économie de plate-forme chez Apple. Cet article, qui ancre l’analyse dans les années 1990 et l’expérience d’Apple avec son premier produit de plate-forme (l’iPod), explore les transformations des politiques de plate-forme d’Apple, en termes stratégiques, organisationnels et financiers. Contrastant nettement avec les recherches précédentes en économie, il démontre comment Apple, dans le contexte d’une concurrence rude avec Samsung/Android, a finalement construit sa stratégie de plate-forme sur des avantages compétitifs spécifiques dans le design des semi-conducteurs, ce qui lui a permis ensuite d’introduire des systèmes d’exploitation et des applications de premier ordre. Ce faisant, cet article analyse les débats internes et les tentatives pour redéfinir les stratégies de plate-forme après des échecs dans ce domaine. L’objectif est d’expliquer comment, pourquoi et dans quelles circonstances les acteurs ajustent et réajustent les stratégies de plate-forme par des processus relationnels et continus.
Leçons sur le retard

Published: May 2020

La pandémie a transformé notre rapport au temps, en nous confrontant à notre hantise du retard et en nous obligeant à reconsidérer nos priorités. Quels enseignements en tirer ? Comment mieux accorder son rythme personnel et le temps commun ? Comment certaines entreprises cherchent-elles à rentabiliser le « temps perdu » ? Quelle place faire dans nos vies aux « temps morts » et à l’expérience même de la perte ? Cette période de suspension temporelle d’une ampleur inédite que nous traversons est une occasion d’expérimenter un autre rapport au temps.
L’État face à ses agents : la question statutaire dans le débat politique sous la III e République (1870-1940)
Authors: Bouchard Laurent
Published: May 2020

La problématique du statut de la fonction publique occupe l’espace politique français depuis le développement d’une bureaucratie administrative au xix e  siècle. Face à l’absence de règles juridiques générales, tous les régimes successifs vont ainsi s’interroger sur la pertinence d’une démarche visant à fixer un statut légal à leurs agents publics. L’émergence progressive d’un État-providence, essentiellement sous la iii e  République, renforce encore ces interrogations. Au cœur des préoccupations sur le sens et la nature de l’action de l’État, cette question stratégique conjugue cependant des exigences contradictoires. D’un côté, un besoin croissant d’efficacité pour les gouvernants face à la hausse des dépenses publiques ; et, de l’autre, les revendications corporatistes puis syndicales d’agents aspirant à plus de sécurité juridique. Pouvant permettre un compromis, l’idée d’un statut légal va ainsi se heurter à une hostilité mutuelle grandissante entre ces différents « corps » de l’État. Largement héritées des conceptions administratives napoléoniennes, faisant de l’administratif l’outil docile du politique, ces oppositions empêcheront jusqu’à la fin du régime la formation d’une majorité parlementaire malgré la multiplicité des tentatives. Il fallut donc attendre le consensus des mouvements de résistance à la Libération pour que ce « serpent de mer » de la vie politique française trouve sa concrétisation avec la loi du 19 octobre 1946.
La gouvernance hospitalière à l’heure du Big Data
Authors: Conan-Brossier Nathalie
Published: May 2020

Alors que le Big Data et l’intelligence artificielle révolutionnent les pratiques médicales (diagnostiques et curatives) à grand bruit, tant dans la communauté scientifique qu’auprès du public, leur usage dans le domaine de la gestion des structures de soin reste confidentiel. Dans un contexte budgétaire contraint, ces grandes masses de données et leur traitement pourraient modifier la gouvernance hospitalière en permettant au Directeur d’Hôpital de disposer d’informations pertinentes et d’outils experts d’aide à la décision. Une enquête auprès d’hôpitaux français, comptant 40 répondants, permet cependant de constater le peu de maturité de ces technologies au service de la gestion. Les managers hospitaliers y entrevoient cependant un mécanisme facilitant leur prise de décision future.
Analyse de l’évolution de l’appareil gouvernemental central en Chine
Authors: Ma Liang , Christensen Tom
Published: May 2020

La structure des institutions politiques et administratives est importante pour la réalisation des objectifs publics. Elle n’est cependant pas figée : elle peut évoluer en raison de processus environnementaux et culturels, ou sous l’effet de changements de direction. Les changements structurels dans l’appareil gouvernemental central figurent en bonne place dans le courant de littérature récent sur la réforme et le changement, mais on sait peu de choses sur les changements structurels dans les contextes autres que ceux des démocraties occidentales. Dans le présent article, nous analysons les principaux types de changements structurels survenus au cours des 70 dernières années dans l’appareil gouvernemental central en Chine, de même que les raisons possibles à leur origine. Nous observons des profils intéressants de changements structurels en accord avec les évolutions administratives. Grâce aux perspectives multiples de la théorie de l’organisation, ceux-ci peuvent s’expliquer principalement par les cycles politiques ou les mesures prises par les responsables centraux, mais ils ont aussi été influencés par des éléments culturels, la croissance économique et la transformation sociétale. Remarques à l’intention des praticiens Nous analysons les principaux profils de la restructuration organisationnelle du gouvernement central chinois opérée entre 1949 et 2016. Il apparaît que les cycles politiques et la réforme et le développement économiques sont les principaux facteurs de l’évolution structurelle. Les résultats indiquent que si la volonté politique des hauts dirigeants joue un rôle décisif dans la conduite des réformes structurelles, les réformes institutionnelles ne dépassent généralement pas encore le stade du discours et du symbolisme, et ne transforment pas de manière substantielle le paysage de l’architecture gouvernementale. Les réformes structurelles durables sont difficiles à bien mettre en œuvre, ce qui laisse penser que d’autres solutions sont peut-être nécessaires pour simplifier les processus administratifs et améliorer la coordination entre les agences.
Quo Vadis ? Le gouvernement local en Turquie après les réformes de la gestion publique
Authors: Tan Evrim
Published: May 2020

Dans les années 2000, la Turquie a réformé son système d’administration publique conformément aux principes du nouveau management public (NMP) en optant pour un système plus décentralisé. Même si l’objectif initial du processus de réforme est de parvenir à un système de gestion publique décentralisé et plus efficace, on peut se demander si cet objectif sera jamais atteint au vu des données empiriques et des statistiques officielles. Dans le présent article, nous analysons les législations des gouvernements locaux, le pouvoir d’appréciation du gouvernement central dans la gouvernance locale et les évolutions dans le statut du gouvernement local dans la gouvernance publique pour présenter l’évolution du système de gouvernement local en Turquie pendant le gouvernement du Parti de la justice et du développement. Remarques à l’intention des praticiens L’expérience de la Turquie dans la réforme de la gestion publique ressemble aux modèles de réforme du NMP dans les pays de tradition napoléonienne. Comme dans ces pays, l’accent a été mis sur les pratiques managériales plutôt que sur les éléments participatifs en vue d’améliorer l’efficience et l’efficacité des services publics. Pourtant, les observations faites en Turquie vont à l’encontre de l’idée que les réformes managériales permettront à elles seules, sans améliorer la gouvernance démocratique locale, d’améliorer l’efficience et l’efficacité des services publics.
Voir l’invisible

Published: May 2020

On dit souvent qu’il faut le voir pour le croire. Cet article tente de montrer, que bien au contraire, il faut sans doute le croire pour le voir. Notre vision n’est en effet pas le miroir de la réalité extérieure. Grâce à l’étude de la perception visuelle à l’état normal ainsi qu’à la suite d’une lésion cérébrale, nous pouvons maintenant mesurer la part cérébrale et cognitive dans le traitement visuel. L’auteure présente ici différentes formes de dissociations entre perception et conscience chez des patients présentant des amputations du champ visuel qui permettent de redéfinir la frontière entre visible et invisible et de dévoiler le secret des processus qui déterminent notre façon de voir le monde.

Published: May 2020

This article reviews recent federal and state policy changes in response to the COVID-19 pandemic that affect health care and quality of life for older adults. Specific regulations and guidelines issued at the state and federal level have increased access and provided additional funding for essential services and supports. Many of these changes are temporary and have the potential to improve care beyond the immediate crisis. This period of greater flexibility offers the opportunity to accrue evidence on quality and access to influence sustained change. [Journal of Gerontological Nursing, 46(6), 19–23.]
Legacy seismic reflection data from the Great Lakes: recovery and applications
Authors: Todd B J , Lewis C F M , Russell H A

Published: May 2020

Great Lakes legacy geoscience data have been recovered and processed for inclusion in the Geological Survey of Canada's Expedition Database. Interpretation of seismic reflection data from Lakes Ontario and Huron reveals sediment thickness and depth to bedrock;
these measurements contribute to the surficial framework geology within the Canada-3D project and southern Ontario 3-D geological modelling. In addition, seismostratigraphic analysis of the legacy data reveals the sediment deposition history and contributes to understanding the evolution of these
two Great Lakes.
Mineralogy, geochemistry, grain size and pebble componentry of the Newmarket Till and the Dummer Moraines in the Kaladar-Tweed-Belleville area of eastern Ontario

Published: May 2020

Downflow glacial dispersal was investigated across the southern Ontario Canadian Shield-Paleozoic boundary along two detailed transects with surficial sediment sampling, sub-parallel to the dominant NNE-SSW transport direction. The transects started on the
Shield, transited the Shield-Paleozoic boundary and extended into the Paleozoic basin, with the target sediments being the Newmarket Till and the Dummer Moraines. Geochemistry and mineralogy analyses of the clay + silt (<0.063 mm) size fraction, and pebble componentry provide the data
required to elucidate the provenance of these two glaciogenic sediment formations, and their potential relationship to each other. Till thickness increases from <2 m (on the Shield) to >=10 m (on the Paleozoic basin) within 1 km south of the Shield-Paleozoic boundary. The
Newmarket Till and Dummer Moraines both consist of carbonate-rich glaciogenic sediments, resultant from source material input dominated by limestone, shaly limestone and dolostone of the Paleozoic Gull River, Bobcaygeon and Verulam formations. Based on data from this study (matrix mineralogy and
geochemistry, pebble componentry), we conclude that the Dummer Moraines are best termed as pebble-, cobble-, boulder-rich facies equivalents of the Newmarket Till. This study highlights the rapid transition in till matrix and clast content when transitioning from hard Canadian Shield lithologies to
Paleozoic carbonate rocks and complexities along different glacial flowlines.
Hydrogeophysics data acquisition for the characterization of hydraulic properties of the Vars-Winchester esker, southeastern Ontario
Authors: Paradis D , Pugin A J -M , Crow H L , Oldenborger G A , Russell H A J , Melaney M
Published: May 2020

A general workflow is proposed to characterize hydraulic properties of unconsolidated aquifers from geophysical data. Three-dimensional hydraulic property models are essential for groundwater flow and solute transport studies aimed at assessing water resources
sustainability. Spatial coverage offered by conventional hydraulic characterization approaches based on hydraulic tests in wells are; however, often limited due to the time required to perform hydraulic tests, especially when high-resolution and/ or large complex areas need to be characterized. On
the other hand, geophysical surveys can reveal important architectural features of an aquifer system; however, the quantification of geophysical attributes into hydraulic properties is difficult to achieve under field conditions. To overcome those limitations, a hydrogeophysical approach based on
the definition of site-specific relationships between collocated geophysical and hydraulic data is proposed to allow the translation of geophysical attributes into hydraulic properties. The development and application of this approach that is currently underway for the Vars-Winchester esker system
in south-east Ontario is reported here.
High-resolution seismic reflection profiles for groundwater studies of the Vars-Winchester esker, southern Ontario
Authors: Pugin A J -M , Crow H L , Brewer K , Cartwright T , Dietiker B , Griffiths M , Paradis D
Published: May 2020

As part of a hydrogeophyscial study of the Vars-Winchester esker three seismic profiles have been acquired using a novel in-house two component (horizontal and vertical) Microvibe seismic source with a 48-channel, three component landstreamer. This new hardware
has allowed for the acquisition and processing of very high-resolution 2-D images of the esker for groundwater exploration. Following the acquisition of the profiles, four boreholes have been drilled to bedrock. The lithologies of the esker system such as marine mud (silt and clay), sand, gravel,
and diamicton, are well characterised by the seismic facies and shearwave velocities.
Downscaling SMAP soil moisture using radarsat constellation mission (RCM) compact polarimetric SAR data: A case study in southern Ontario
Authors: Li J , Wang S , Russell H A
J
Published: May 2020

This paper presents an improved algorithm for downscaling SMAP soil moisture using C-band SAR data. It is developed using multi-temporal C-band Radarsat Constellation Mission (RCM) compact polarimetric (CP) SAR data. In this improved algorithm, the effect of
vegetation on soil moisture retrieval from SAR data is minimized by using a normalized scattering based empirical model, in which vegetation contribution is quantified using the volume scattering derived from RCM CP decomposition. The influence of soil surface roughness is eliminated by using
multi-temporal data. The multi-temporal SMAP soil moisture and RCM CP data (simulated from Radarsat-2 QuadPol data) are the only inputs of this downscaling model. The model is tested in southern Ontario, Canada to downscale 36 km resolution SMAP soil moisture to 1 km. The downscaled results have
good agreement with the in-situ soil moisture collected in June of 2017 with an unbiased root-mean-square-error (RMSE) of 0.047 m3/m3 and a coefficient of determination (R2) of 0.43. The results suggest that the improved algorithm can be applied for C-band RCM CP data to provide continuous soil
moisture mapping over large area at higher resolutions because of RCM's high-revisit frequency and large areal coverage characteristics.
Stochastic hydrogeological modelling workflow in a glacial sedimentary basin, southern Ontario
Authors: Benoit N , Marcotte D , Molson J W , Bajc A F , Russell H A J
Published: May 2020

The focus of this study is to explore and assess the uncertainty related to geological heterogeneity in regional groundwater flow models. A stochastic approach is adopted in which the hydrostratigraphic architecture and respective hydrofacies variability directly
controls the three-dimensional hydraulic conductivity (K) field. The following procedural steps were applied to develop the stochastic flow model: 1) generation of multiple equivalent hydrostratigraphic models honouring observed hydrostratigraphic units and stratigraphic transitions; 2)
determination of the statistical scalar K distribution for each hydrostratigraphic unit along with the respective spatial correlation at the local-scale; 3) upscaling of the scalar K field (quasi-point) to its full 3-D tensor at the regional scale (block); 4) determination of the K-tensor structures
and simulation of the K-tensor for hydrogeological models; 5) calibration of the models by numerical inversion of the K-tensor and preserving their component correlations including the recharge rate; and 6) quantification of the uncertainties in the groundwater flow model. The capability and
performance of the suggested workflow is illustrated using a case study in southern Ontario. Results highlight the efficiency of the method in assessing model uncertainties and their impact on regional groundwater flow models.
A política proibicionista aplicada à guerra às drogas como combustível para o crescimento do crime organizado no Brasil
Authors: Correia Marcus Vinícius Honório , Santigo Felipe Amore Salles
Published: May 2020

O artigo apresenta uma análise da política proibicionista embasadora da guerra às drogas atualmente praticada no Brasil que, como efeito reverso, financia e empodera o crime organizado responsável pela propagação do medo e pavor que assolam a sociedade. Muito embora seja, em determinados grupos jurídicos, vangloriada e disseminada como o meio mais eficaz para a erradicação do uso e do comércio de substâncias ilícitas, a política proibicionista de guerra às drogas, na prática, não alcança tal pretensão, acabando por ser utilizada de forma deturpada somente para determinada parcela da sociedade, que é a da população mais pobre. Assim, o objetivo deste trabalho é demonstrar que a política proibicionista de drogas, ao invés de alcançar seus escopos, acaba por beneficiar o crime organizado no Brasil, eis que, cada vez mais, chega à obtenção de lucros descomunais com o mercado clandestino do tráfico de drogas, amplia seu poder de combate frente ao Estado, e se propaga rapidamente em todo o território nacional com suas ideologias excessivamente truculentas. É esta hipótese que se busca confirmar a partir de uma breve revisão de literatura aplicada ao tema.
La business judgment rule ante la determinación del riesgo permitido en el delito de administración desleal
Authors: Coca Vila Ivó
Published: May 2020

Pese a que la Ley de Sociedades de Capital (LSC) diversifica el régimen de responsabilidad del administrador societario, tratando de forma más severa la infracción del deber de lealtad (art. 227 LSC) que la del deber de diligencia (art. 225 LSC), ambas clases de infracciones son susceptibles de integrar por igual el tipo de administración desleal del nuevo art. 252 CP. El objetivo del presente trabajo radica en examinar de qué manera la regulación mercantil de los deberes fiduciarios del administrador y, en especial, la regla de protección de la discrecionalidad empresarial del art. 226 LSC (Business Judgment Rule) debería condicionar los espacios de riesgo permitido ante la adopción de negocios de riesgo susceptibles de ser encuadrados en el nuevo tipo de administración desleal del art. 252 CP.
Painful intercourse. Dyspareunia and Vaginismus
Authors: Hajnalka Győrfy
Published: May 2020

Dyspareunia and Vaginismus are two clinical forms of painful sexual intercourses, affecting mostly the premenopausal women with vaginal atrophy, and young 18-24 years old women. The symptoms may be caused by medical and gynaecological problems. The unpleasant intercourse has got a huge impact on the partner and the quality of marriage. Some women accuse themselves; some are aggressed, and their partner develop sexual aversion, anxiety, shame, depression, hostility, anger. The understanding partner is opened to communication and supports the healing process. Psychotherapy is needed for both partners, with clearly defined objectives which informs the couple that complete remission is very difficult to obtain. Women who suffer of dyspareunia have an increased sensitivity to pain. In the case of dyspareunia caused by medical conditions, healing consists of relaxation methods, exercises, progressive muscle relaxation and variation of sexual life „temperature” of the relationship, involving the partner in the therapy too. The client needs to feel that she is beautiful, attractive. She needs to maintain a permanent dialog with the partner. This is an important marital problem and therapists need to respect the values of the family involved. For the future it is important to help women and couples (classical, homosexual, disabled) to cure painful sexual intercourse and improve their intimacy.

Karakteristik Aliran Di Belakang Gundukan (Bump) Segitiga Pada Plat Datar
Authors: P. Setyo Hariyadi S.
Published: May 2020

Aliran viscous yang melewati sebuah pengganggu berbentuk bump, umumnya akan mengalami penurunan tekanan di sisi upstream dan kenaikan tekanan di sisi downstream. Saat momentum aliran fluida tidak dapat melawan kenaikan tekanan dan gesekan dengan permukaan maka aliran fluida akan terseparasi. Titik dimana mulai terjadi gejala separasi disebut titik separasi. Daerah setelah titik separasi mempunyai tekanan yang lebih kecil daripada daerah di sisi upstream sehingga mengakibatkan perbedaan tekanan yang besar. Akibat perbedaan tekanan ini, maka akan terjadi gaya drag pada benda. Bentuk bump yang digunakan pada studi numerik ini adalah segitiga dengan freestream sebesar 9.75 m/s dan 15.5 m/s. Penelitian ini dilakukan dengan simulasi numerik mengunakan software simulasi dengan model turbulen k – ε Realizable. Model benda uji berupa plat datar yang ditambahi dengan bump. Adanya bump pada pelat datar mengakibatkan aliran menjadi terseparasi sehingga menimbulkan penambahan gaya total drag sepanjang pelat datar. Separasi massive pada bump segitiga terjadi akibat momentum aliran tidak mampu mengatasi advarse pressure gradient dan tegangan geser antara permukaan bump dengan aliran fluida, sehingga untuk harga Re yang lebih besar akan mengakibatkan letak titik separasi lebih tertunda.

Investigación sobre el sistema de abastecimiento del antiguo alcázar de los arzobispos en Alcalá de Henares

Published: May 2020

Research on the supply system of the Alcazar of the archbishops in Alcalá de HenaresSeven years after the reconquest in 1118, Alkal’a Nahar (Alcalá de Henares) to Muslims, thanks to the Toledo archbishop, Bernardo de Sedirac, King Alfonso VII donates this population, to the archbishopric of Toledo. During the Muslim domination, a fortress with an important suburb had been built on the nearby hills, known as Alcalá la Vieja which, from that moment, was gradually abandoned, to settle on the plain, next to the old Church of San Justo. The archbishops were aware of the historical and religious importance of this site and with their policies, they were reinforcing and attracting more population. Most of the researchers think that it was Ximénez de Rada (1209-1247), who began the construction of the headquarters of the Toledo archbishops in Alcalá de Henares, formed by a fortress and a walled enclosure, probably over what there was it has been an extensive agricultural farm. Associated with this, there are news of the existence of waterwheel, from the Muslim era in this place. On the other hand, there is a reference that places around 1300, the construction of a “viaje de agua” for water supply. Little else was known about the supply system of the Alcazar. Thanks to the research carried out, we have learned that the construction of said infrastructure is based on the ancient Arab technique, known as qanat. These are mines that drain the aquifer, about two kilometers upstream, to the north and transport the water to the walled enclosure. The main advantages of this system of supply, is that the water is captured far from the fortification and can also be tubed and taking advantage of the existing slope, maintaining the pressure, to make the water sprout above ground level, forming sources.
Metamorfose do calouro: um estudo da evolução das expectativas acadêmicas de ingressantes em administração
Authors: Muraoka Marcia Regina , Santos Jorge Alberto dos
Published: May 2020

Expectativas acadêmicas são definidas como aspirações ou sonhos que os estudantes têm com o ensino de graduação. O conhecimento das expectativas acadêmicas é importante para a Instituição de Ensino Superior (IES). Ele permite a identificação das discrepâncias entre as expectativas e a realidade e a implementação de ações que ajudem os estudantes a uma melhor adaptação à realidade da vida acadêmica. Esta pesquisa investigou as expectativas acadêmicas dos alunos ingressantes do Curso de Graduação em Administração da Universidade Federal de Viçosa – Campus Florestal (CGA/F) nos meses de março e outubro de 2018. Trata-se de um estudo quantitativo-descritivo com dados coletados por meio do Questionário de Percepções Acadêmicas: Versão A – Expectativas – Versão brasileira (QPA-E/B) em uma perspectiva longitudinal restrita. O resultado mostrou que o contato com a realidade altera as expectativas acadêmicas dos estudantes. Ficou evidente na pesquisa que acontece não apenas a visão irrealista dos estudantes quando ingressam na universidade – que ficou conhecido na literatura com o termo ‘mito do calouro’- freshman myth – mas também uma transformação gradual deste estudante, o que aqui se denominou ‘metamorfose do calouro’.
Effect of animal-assisted therapy on engagement of rural nursing home residents
Authors: Martindale Brianne P.
Published: May 2020

Passivity is a major debilitating problem for nursing home residents. Reports show that anywhere from 24 to 90 percent of residents living in nursing homes exhibit passive behaviors, apathy, and functional decline due to inactivity. The purpose of this study was to examine the effects that animal-assisted therapy (AAT) has on the passivity, engagement, and mood of rural nursing home residents. Using a quasi-experimental design, researchers assigned 10 rural nursing home residents to AAT and 10 rural nursing home residents to traditional recreation therapy interventions. Each group received five, one- hour sessions during a span of six weeks. AAT was shown to significantly decrease passive behaviors and significantly improve mood. The traditional recreation therapy control group did show improvements but none were significant.

It provides a context for the application of recreation therapy interventions and offers an examination of clients in a manner that is holistic and focused on the strengths (rather than the deficits) of the individual. In this article, the roots of positive psychology are discussed and defined, the three pillars of positive psychology are described, and finally, the relationship between positive psychology and recreation therapy is delineated. Positive psychology offers the field of recreation therapy with a firm foundation for theoretical growth and practice.

Therapeutic riding centers: Unexpected benefits
Authors: Shapley, PhD Kathy L. , Flynn, MEd Perry F. , Raven, BS Sarah
Published: May 2020

The benefits of therapeutic horseback riding for clients has been shown to improve physical, emotional, and communication skills.1 However, there is no research examining the benefits of owning or operating a therapeutic horseback riding center. The purpose of this study is to understand the benefits of owning/working at a Professional Association of Therapeutic Horsemanship (PATH) International Certified Riding Center. A multisite case study using semistructured interviews was used to complete this study. Fifteen 1-hour interviews were collected from individuals who own or work at a PATH center. Three themes emerged: Rewards, Cultivating Community, and Elements for Success. The outcomes of this study may provide centers who have not sought PATH certification incentive to seek that level of accreditation.
Aerosol indirect effects on the temperature–precipitation scaling
Authors: Da Silva Nicolas , Mailler Sylvain , Drobinski Philippe
Published: May 2020

Abstract. Aerosols may impact precipitation in a complex way involving their direct and indirect effects. In a previous numerical study, the overall microphysical effect of aerosols was found to weaken precipitation through reduced precipitable water and convective instability. The present study aims to quantify the relative importance of these two processes in the reduction of summer precipitation using temperature–precipitation scaling.
Based on a numerical sensitivity experiment conducted in central Europe aiming to isolate indirect effects, the results show that, all others effects being equal, the scaling of hourly convective precipitation with temperature follows the Clausius–Clapeyron (CC) relationship, whereas the decrease in convective precipitation does not scale with the CC law since it is mostly attributable to increased stability with increased aerosol concentration rather than to decreased precipitable water content.
This effect is larger at low surface temperatures at which clouds are statistically more frequent and optically thicker. At these temperatures, the increase in stability is mostly linked to the stronger reduction in temperature in the lower troposphere compared to the upper troposphere, which results in lower lapse rates.
BAYWRF: a convection-resolving,present-day climatological atmospheric dataset for Bavaria
Authors: Collier Emily , Mölg Thomas
Published: May 2020

Abstract. Climate impact assessments require information about climate change at regional and ideally local scales. In dendroecological studies, this information has traditionally been obtained using statistical methods, which preclude the linkage of local climate changes to large-scale drivers in a process-based way. As part of recent efforts to investigate the impact of climate change on forest ecosystems in Bavaria, Germany, within the BayTreeNet project, we developed a high-resolution atmospheric modelling dataset, BAYWRF, for the region of Bavaria over the thirty-year period of September 1987 to August 2018. The atmospheric model employed in this study, WRF, was configured with two nested domains of 7.5- and 1.5-km grid spacing, centred over Bavaria and forced at the outer lateral boundaries by ERA5 reanalysis data. Based on a shorter evaluation period of September 2017 to August 2018, we evaluate two aspects of the simulations: (i) we assess model biases compared with an extensive network of observational data at both two-hourly and daily mean temporal resolutions, and (ii) we investigate the influence of using grid analysis nudging. The model represents variability in near-surface meteorological conditions well, with a clear improvement when nudging is used, although there are cold and warm biases in winter and summer, respectively. We also present a brief overview of the full dataset, which will provide a unique and valuable tool for investigating climate change in Bavaria with high interdisciplinary relevance. Data from the finest resolution WRF domain are available for download at daily temporal resolution from a public repository at the Open Science Framework (Collier, 2020; https://www.doi.org/10.17605/OSF.IO/AQ58B).
Technical note: Long-term probe misalignment and proposed quality control using the heat pulse method for transpiration estimations

Abstract. Transpiration is a crucial component in the hydrological cycle and a key
parameter in many disciplines like agriculture, forestry, ecology and
hydrology. Sap flow measurements are one of the most widely used approaches
to estimate whole-plant transpiration in woody species; this is due to their
applicability in different environments and in a variety of species as well
as the fact that continuous high temporal resolution measurements of this parameter are possible.
Several techniques have been developed and tested under different climatic
conditions and using different wood properties. However, the scientific
literature also identifies considerable sources of error when using sap flow
measurements that need to be accounted for, including probe misalignment, wounding,
thermal diffusivity and stem water content. This study aims to explore
probe misalignment as a function of time in order to improve measurements during
long-term field campaigns (>3 months). The heat ratio method
(HRM) was chosen because it can assess low and reverse flows. Sensors were
installed in four Pinus halepensis trees for 20 months. The pines were located in a
coastal valley in south-eastern Spain (39∘57′45′′ N
1∘8′31′′ W) that is characterised by a Mediterranean climate. We
conclude that even small geometrical misalignments in the probe placement
can create a significant error in sap flow estimations. Additionally, we
propose that new statistical information should be recorded during the
measurement period which can subsequently be used as a quality control of the sensor
output. The relative standard deviation and slope against time of the averaged
v1v2 were used as quality indicators. We conclude that no
general time limit can be set regarding the longevity of the sensors, and this threshold
should rather be determined from individual performance over time.
Sinonimia y variación léxica en la fraseología española e italiana: propuesta para un diccionario bilingüe bidireccional en línea
Authors: Dal Maso Elena
Published: May 2020

En el presente artículo se ilustra una propuesta enfocada al tratamiento de la variación léxica y de la sinonimia en un diccionario fraseológico en línea en curso de elaboración. El objetivo de dicha propuesta es doble: por un lado, plantear una posible estrategia para dar cuenta de la variación léxica y la sinonimia en el ámbito fraseográfico, y, por otro, contribuir a solucionar algunas de las lagunas existentes hasta la fecha en la fraseografía bilingüe del italiano y del español mediante muestras concretas de fichas pensadas para el medio digital. Como resultado, en los apartados que configuran este ensayo se aclara, en primer lugar, la metodología adoptada para la selección y el análisis del corpus estudiado; en segundo lugar, se ofrecen las fichas lexicográficas, todas ellas elaboradas a partir del concepto de equivalencia funcional (Mellado Blanco 2015) y de la propuesta lexicográfica expuesta en Lončar y Dal Maso (2018) y Dal Maso (2019).
Un inventario de reliquias inédito de San Salvador de Valdediós (Asturias)
Authors: Valdés Gallego José Antonio
Published: May 2020

La iglesia de San Salvador de Valdediós (en Villaviciosa, Asturias), el último monumento de la época del reino asturiano, ha conservado en una hornacina de la capilla mayor un texto en muy mal estado, hasta ahora casi desapercibido y sin descifrar. Fue pintado en rojo sobre el revoco que también sirvió de base a la pintura perrománica. Por medio del retoque fotográfico y la comparación con textos afines de época visigoda y medieval, sobre todo del territorio actual de Asturias, se ha leído una lista redactada en latín de las reliquias que se habían depositado en el altar mayor. Ese inventario está precedido de una fórmula referida a su deposición, con el participio característico recondite. El texto leído abarca once líneas y media e incluye dieciséis reliquias de trece santos, bíblicos o de los siglos III-IV, muy bien ordenados. Predominan las del Salvador, titular de la capilla y del templo. Es similar a otros catálogos asturianos, sobre todo vinculados con el obispado de Oviedo, aunque con la mención singular de santa Basilisa. La disposición y factura de los caracteres, así como la calidad lingüística del texto son notables. La morfología de las letras, las abreviaturas empleadas, un detalle lingüístico, e igualmente las fórmulas y las reliquias consignadas nos permiten conjeturar su cercanía cronológica a la decoración parietal prerrománica de San Salvador, durante una segunda fase del edificio, situada generalmente en torno a 893, año de la consagración o, en cualquier caso, una fecha anterior a 968.

The content of universal and European regional international instruments on protection of labor rights of persons with disabilities is analyzed in the paper. The conclusion is made that Ukraine should take into account the positive foreign experience of the leading countries in the field of state policy of support for persons with disabilities and its implementation. It is justified that the world experience in the field of employment for persons with disabilities will facilitate the practical implementation not only of government programs but also of measures to protect the interests of persons with disabilities. A number of scholarly publications on the subject have been investigated, containing suggestions by scientists to improve promising labor law regarding the manifestations of discrimination on the basis of disability in the field of work. Some theoretically sound recommendations for improving the legal regulation of the protection of the labor rights of persons with disabilities and ensuring that they fulfill their responsibilities were developed. General conclusions have been drawn that the problem of the legal mechanism for the protection of the labor rights of persons with disabilities needs reforming and improvement. Some proposals for improving the legal regulation in this field were given.
