« Partager le revenu ». Pour une nouvelle formule de financement de l’enseignement supérieur qui vient de l’Oregon
Authors: Magni-Berton Raùl
Published: April 2021

Le système actuel d’enseignement supérieur – et notamment son financement – a fait, de longue date, l’objet de nombreuses critiques. Pour répondre à ces critiques, plusieurs propositions visent à accroitre la contribution des étudiants au financement des études supérieures. Alors que l’État et les établissements tendent à proposer des réformes par le financement des étudiants ex ante , les débats scientifiques mettent l’accent sur les avantages des formules ex post . Cet article met en avant quatre critères – incitations inadéquates, redistribution inversée, discordance entre bénéficiaires et financeurs, et inégalité des chances – qui confirment la supériorité des systèmes de financements ex post . Parmi ces systèmes, l’analyse promeut une formule relativement négligée dans les débats français. Traditionnellement appelée « contrat à capital humain » ou « contrat de partage du revenu » (CPR), elle a été introduite Oregon en 2013 sous la forme d’un projet pilote qui, depuis, s’est largement développé aux États-Unis. Cet article analyse ce système de financement, en développe les principes, les avantages et discute de la faisabilité de son introduction dans le contexte français.

Les barèmes, outils d’aide à la décision pour les justiciables et les juges
Authors: Bourreau-Dubois Cécile , Deffains Bruno , Doriat-Duban Myriam , Jeandidier Bruno
Published: April 2021

Dans un contexte français marqué par le développement des barèmes judiciaires, cet article propose une analyse économique de ces derniers, centrée sur les acteurs du litige : juges et justiciables. Après avoir présenté les différentes formes que pouvait prendre un barème judiciaire, l’article, qui prend appui sur une revue de littérature, met en évidence que les barèmes peuvent être envisagés comme des outils d’aide à la décision qui, en fournissant de l’information aux justiciables et en cadrant (plus ou moins fortement selon leur nature) le pouvoir discrétionnaire des juges, jouent un double rôle : incitatif et normatif.

Aux origines des disparités de dépenses des départements français : une analyse empirique (2006-2016)
Authors: Duboz Marie-Line , Le Gallo Julie , Houser Matthieu
Published: April 2021

Partant du constat selon lequel les niveaux de dépenses comme de ressources sont très hétérogènes d’un département à l’autre, l’objet de cet article est d’éclairer les origines des disparités de dépenses des départements pour pouvoir s’interroger ensuite sur l’efficacité des mécanismes de péréquation destinés à les réduire. Pour ce faire, nous identifions les variables explicatives des dépenses des départements puis nous mesurons la contribution de chacune d’elles à l’explication des disparités des dépenses départementales. Conduite à partir des données de la Direction générale des collectivités locales (DGCL), notre étude porte sur la période 2006-2016 et distingue au niveau des dépenses totales, les dépenses de fonctionnement des dépenses d’investissement. Nous montrons alors que les disparités de dépenses s’expliquent avant tout par des disparités de ressources, que celles-ci proviennent de dotations de l’État ou d’impôts, ce qui interroge quant au rôle joué par les dépenses sociales considérées souvent comme l’élément majeur expliquant le comportement des dépenses des départements. Par ailleurs, nos résultats permettent de clarifier le poids relatif des mécanismes de péréquation verticale et horizontale dans l’explication des disparités de dépenses des départements tout en conduisant à s’interroger sur leur efficacité relative.

Note on Democracy and Competition: The Role of Ownership Structure in a General Equilibrium Model with Vertical Preferences
Authors: Ghazzai Hend , Hemissi Wided , Lahmandi-Ayed Rim , Mami Kefi Sana
Published: April 2021

Dans cette note, on étudie un modèle d’équilibre général où les individus sont potentiellement des consommateurs, des travailleurs et des actionnaires. On généralise le travail de Kahloul et al. [2017] qui détermine le résultat d’un vote majoritaire entre Monopole et Duopole pour deux structures de propriété particulières extrêmes, en considérant une proportion quelconque d’actionnaires dans la population. On montre que le Duopole est préféré lorsque les non-actionnaires représentent une majorité dans la population. Autrement, le résultat du vote majoritaire dépend de la proportion d’actionnaires et de la dispersion des individus par rapport à leur intensité de préférence pour la qualité relativement à leur dispersion par rapport à leur sensibilité à l’effort.
L’information sur les retraites modifie-t-elle les décisions d’emploi des seniors ?
Authors: Charni Kadija , Gouaref Ilia
Published: April 2021

Cet article évalue l’impact du dispositif qui informe les travailleurs proches de l’âge de la retraite, concernant les cotisations et les futures pensions, sur la décision de participer au marché du travail. En utilisant la méthode des doubles différences sur des données longitudinales en France, nous exploitons la discontinuité des seuils d’âge introduite par cette mesure pour identifier ses impacts sur les décisions d’offre de travail. Nous constatons que la réception des lettres sur l’information de retraite influence ces décisions de différentes manières. Pour les personnes qui ont eu une carrière longue, les informations sur la retraite modifient les décisions de participation au marché du travail par une baisse de l’offre de travail. Cette dernière se traduit par une augmentation des sorties vers l’inactivité économique. En revanche, les travailleurs avec des postes qualifiés ont tendance à travailler plus longtemps, dans le but d’améliorer leurs revenus à la retraite.
Tension au travail et adhésion syndicale : une étude empirique à partir de données françaises
Authors: Guillot Olivier , Jaoul-Grammare Magali , Terraz Isabelle
Published: April 2021

Cet article vise à déterminer si la tension au travail (job strain), pouvant s’accompagner d’un manque de soutien social (iso-strain), accroît la propension des salariés à se syndiquer. L’étude s’appuie sur l’enquête REPONSE de 2011. Les résultats ne montrent aucun lien significatif entre la charge psychologique de travail et l’appartenance à un syndicat. Mais il apparaît qu’être exposé à une certaine forme d’iso-strain a un effet positif sur la probabilité de syndicalisation. Les conclusions de cette étude vont dans le sens de l’approche en termes de frustration/agression ou du modèle « exit-voice », reliant l’adhésion syndicale à l’insatisfaction au travail et au désir d’agir sur ses conditions de travail.
Stabilized finite element methods based on multiscale enrichment for Allen-Cahn and Cahn-Hilliard equations
Authors: Wen Juan , He Yaling , He Yinnian , Wang Kun
Published: April 2021

In this paper, we investigate fully discrete schemes for the Allen-Cahn and Cahn-Hilliard equations respectively, which consist of the stabilized finite element method based on multiscale enrichment for the spatial discretization and the semi-implicit scheme for the temporal discretization. With reasonable stability conditions, it is shown that the proposed schemes are energy stable. Furthermore, by defining a new projection operator, we deduce the optimal \begin{document}$ L^2 $\end{document} error estimates. Some numerical experiments are presented to confirm the theoretical predictions and the efficiency of the proposed schemes.
Hadamard Semidifferential, Oriented Distance Function, and some Applications
Authors: Delfour Michel C.
Published: April 2021

The Hadamard semidifferential calculus preserves all the operations of the classical differential calculus including the chain rule for a large family of non-differentiable functions including the continuous convex functions. It naturally extends from the \begin{document}$ n $\end{document}-dimensional Euclidean space \begin{document}$ \operatorname{\mathbb R}^n $\end{document} to subsets of topological vector spaces. This includes most function spaces used in Optimization and the Calculus of Variations, the metric groups used in Shape and Topological Optimization, and functions defined on submanifolds.

Certain set-parametrized functions such as the characteristic function \begin{document}$ \chi_A $\end{document}of a set \begin{document}$ A $\end{document}, the distance function \begin{document}$ d_A $\end{document} to \begin{document}$ A $\end{document}, and the oriented (signed) distance function \begin{document}$ b_A = d_A-d_{ \operatorname{\mathbb R}^n\backslash A} $\end{document} can be used to identify a space of subsets of \begin{document}$ \operatorname{\mathbb R}^n $\end{document} with a metric space of set-parametrized functions. Many geometrical properties of domains (convexity, outward unit normal, curvatures, tangent space, smoothness of boundaries) can be expressed in terms of the analytical properties of \begin{document}$ b_A $\end{document} and a simple intrinsic differential calculus is available for functions defined on hypersurfaces without appealing to local bases or Christoffel symbols.

The object of this paper is to extend the use of the Hadamard semidifferential and of the oriented distance function from finite to infinite dimensional spaces with some selected illustrative applications from shapes and geometries, plasma physics, and optimization.
On the family of cubic parabolic polynomials
Authors: Alves Alexandre , Salarinoghabi Mostafa
Published: April 2021

For a sequence \begin{document}$ (a_n) $\end{document} of complex numbers we consider the cubic parabolic polynomials \begin{document}$ f_n(z) = z^3+a_n z^2+z $\end{document} and the sequence \begin{document}$ (F_n) $\end{document} of iterates \begin{document}$ F_n = f_n\circ\dots\circ f_1 $\end{document}. The Fatou set \begin{document}$ \mathcal{F}_0 $\end{document} is the set of all \begin{document}$ z\in\hat{\mathbb{C}} $\end{document} such that the sequence \begin{document}$ (F_n) $\end{document} is normal. The complement of the Fatou set is called the Julia set and denoted by \begin{document}$ \mathcal{J}_0 $\end{document}. The aim of this paper is to study some properties of \begin{document}$ \mathcal{J}_0 $\end{document}. As a particular case, when the sequence \begin{document}$ (a_n) $\end{document} is constant, \begin{document}$ a_n = a $\end{document}, then the iteration \begin{document}$ F_n $\end{document} becomes the classical iteration \begin{document}$ f^n $\end{document} where \begin{document}$ f(z) = z^3+a z^2+z $\end{document}. The connectedness locus, \begin{document}$ M $\end{document}, is the set of all \begin{document}$ a\in\mathbb{C} $\end{document} such that the Julia set is connected. In this paper we investigate some symmetric properties of \begin{document}$ M $\end{document} as well.
Dynamics of a depletion-type Gierer-Meinhardt model with Langmuir-Hinshelwood reaction scheme
Authors: Chen Mengxin , Wu Ranchao , Xu Yancong
Published: April 2021

A depletion-type reaction-diffusion Gierer-Meinhardt model with Langmuir-Hinshelwood reaction scheme and the homogeneous Neumann boundary conditions is introduced and investigated in this paper. Firstly, the boundedness of positive solution of the parabolic system is given, and the constant steady state solutions of the model are exhibited by the Shengjin formulas. Through rigorous theoretical analysis, the stability of the corresponding positive constant steady state solution is explored. Next, a priori estimates, the properties of the nonconstant steady states, non-existence and existence of the nonconstant steady state solution for the corresponding elliptic system are investigated by some estimates and the Leray-Schauder degree theory, respectively. Then, some existence conditions are established and some properties of the Hopf bifurcation and the steady state bifurcation are presented, respectively. It is showed that the temporal and spatial bifurcation structures will appear in the reaction-diffusion model. Theoretical results are confirmed and complemented by numerical simulations.
From arsenic to DDT: Pesticides, Fascism and the invisibility of toxic risks in the early years of Francoist Spain (1939-1953)
Authors: Pérez-Criado Silvia , Bertomeu Sánchez José Ramón
Published: April 2021

This paper reviews the way in which Spanish agriculture climbed onto the pesticide treadmill. We claim that Fascist policies and expert advice assembled in the early 1940s accelerated the introduction of pesticides into Spanish agriculture and promoted the emergence of the Spanish pesticide industry in the times of autarky. Agricultural engineers were the key protagonists in this process, but other human and non-human actors also played a pivotal role: a new pest (the Colorado beetle), Francoist politicians, farmers, landowners and industry managers. Our focus is on the use of pesticides against the Colorado beetle (the main threat to the potato crop), and the transition from arsenical pesticides to DDT during the 1940s. We discuss how the politics of autarky offered new opportunities for developing agronomic programmes and the chemical industry and led to the creation of the Register of Pesticides in 1942. We also discuss the role of these regulations in concealing the risks of pesticides from farmers and food consumers. Arsenic pesticides became sources of slow poisoning and tools for social control while reinforcing the alliance of agricultural engineers and Fascist politicians in their autarkic and authoritarian projects. When DDT arrived in Spain, the agricultural engineers praised the low toxicity it had demonstrated (compared to lead arsenate) in its first uses in public health and in military campaigns in Italy. Indeed, the data concerning its potential dangers disappeared from view thanks in part to a large multimedia campaign launched to promote the introduction of the new organic pesticides in Spanish agriculture, which is described at the end of the paper.
Between modernity and tradition: the formation of a psychoanalytical culture during the Franco dictatorship
Authors: Lévy Lazcano Silvia
Published: April 2021

The aim of this work is to analyze the process by which psychoanalysis categories joined scientific and popular culture in Francoism. To do so, we will start with the criticism and reinterpretations that different experts did on Freud’s theory to adapt it to the new political-social context. This analysis will allow us to show how reappropriation and signification of a progressive and modern theory was achieved based on the doctrinal principles of national-Catholicism. From here on, we will analyze the incorporation of psychoanalytic language and ideas into several mass media, confirming the consolidation of psychoanalysis as a cultural framework in Spain.
Medieval echoes. Reflection on political theories and cultural trends from European Middle Ages during American Wars of Independence and Between the States
Authors: Sánchez Sánchez Xosé M.
Published: April 2021

This article examines the influence of formulations and lines of European medieval thought and culture during the two main processes of American political history: the American Wars of Independence and Between the States. In these moments of enormous significance, we can perceive a series of formulations alive since Middle Age centuries; principles with a no evident but relevant influence in mentality and perception during the conflicts. These are: federalism, constitutionalism, canon law, the concept of war, the reception of the work of Dante Alighieri and his ‘Divina Commedia’ and the reception of chivalric medieval culture and the Arthurian tradition.
An Exploratory Study on the Effect of Artificial Intelligence-Enabled Technology on Customer Experiences in the Banking Sector
Authors: El-Gohary Hatem , Thayaseelan Aksaya , Babatunde Simeon , El-Gohary Salma
Published: April 2021

This study investigates how artificial intelligent technology in the banking sector has affected consumers’ overall experience. It focuses on how consumers’ personal digital transformation has affected digital banking development and how this further affects consumer’s expectations and experience. It assesses how banks use Artificial Intelligent Virtual Agents such as Chatbots to transform how consumers use their banking facilities. Lastly, this study investigates the scope of neobanks in the banking sector. The study found that digital transformations have led to an increase in consumers’ expectations from their banks. Whilst banks revolutionise their customer service offerings through virtual agents, customers are not engaging with these at an expected rate. Findings revealed that Neobanks are not operating at their expected traction due to consumer knowledge gaps, occasioned by a lack of advertised information to customers from their banks.

Reconstruction of bone defect due to a disease or a trauma can use autograft, allograft, xenograft or synthetic bonegraft as the bone substitute material. However, in particular cases, it is required a material that has a specific resorption characteristic, beside owning excellent bioactive properties, such as β-tricalcium phosphate (β-TCP). In this study, we report the synthesis of β-TCP particles with mesopores structure by using chitosan and aloe vera as templates. A solution of (NH4)2HPO4 was added dropwise into solution of Ca(NO3)2·4H2O and the template at 85°C for 2 hours, and subsequently aged for 3 hours. Then, the formed precipitate was washed and centrifuged repeatedly prior to drying at 80°C for 24 hours. Finally, the dried precipitate was calcined at 900°C for 1 hour to obtain β-TCP powder. Phase identification and mesopores structure were analyzed using X-ray diffraction (XRD), while the existence of functional groups was identified by Fourier-transform infrared (FTIR) spectroscopy. Microstructure and particle size distribution were characterized by scanning electron microscopy (SEM) and particle size analyzer (PSA), respectively. XRD analysis shows that β-TCP is dominant with the presence of small amount of impurities. Furthermore, low angle peak in XRD analysis indicates the formation of mesopores structure. From the SEM and PSA analysis, the morphology of both TCP-K and TCP-KA particles showed more large agglomerates and more heterogeneous particle size distribution due to the addition of the biopolymers in the synthesis of β-TCP.

Published: April 2021

Atypical hemolytic–uremic syndrome (aHUS) is a form of thrombotic microangiopathy that occurs due to dysregulation of alternate pathway of complement system, which progressively causes systemic complications, end-stage renal disease, and death. As prognosis is poor compared to typical hemolytic–uremic syndrome, early diagnosis and treatment is crucial for favorable outcome. We came across seven patients of aHUS in our pediatric intensive care unit in the last 5 years. Plasma exchange (PE) along with immunosupressives was used for treatment. First child who did not receive PE died. Rest six patients underwent PE and attained hematological remission; however, one later on progressed to chronic kidney disease and expired. All others are on regular follow-up and doing well. A high index of suspicion is required to diagnose aHUS. Early PE can give a better prognosis.

Power Sharing and Control by Droop Controller with Advanced Filter Design: A Case Study in Lock-down Periods
Authors: Modi Bharat , Lalwani Mahendra
Published: April 2021

In the lock-down period, the islanding mode of operation with droop controllers has several advantages in the alternating current grid. This study focuses on an improvised droop controller. It consists of an advanced filtering segment embedded with a conventional droop controller, which overcomes the drawback of droop controllers of the non-handling of non-linear loads in an ordinary situation. A selective harmonic elimination technique in grid-connected mode and lock-down mode and an advanced filter embedded with droop control are used so that the proposed controller can also work as an Active Harmonic Filter (AHF). The simulation results in different cases show that the proposed controller can control the active and reactive power in the lock-down period as well as the harmonics in the normal period up to an extent.

ABSTRACT

Although there have been a lot of supports from the government and local authorities to reduce the dependency on forest resources, the fact of hunting wildlife for food and selling is still common in the remote and mountainous areas of Thua Thien Hue province. This study aimed to assess the current situation and fluctuations in hunting wildlife in Thua Thien Hue Sao la Nature Reserve. The study used household interviews, key informant interviews, group discussions, expert interviews, inheriting the results of biodiversity monitoring surveys, wildlife data from camera trap systems …, to assess changes in their hunting activities, and correlation between the area that is rich in wildlife and the system of wildlife trap of local people in the buffer zone of Thua Thien Hue Sao la Nature Reserve in Thua Thien Hue province. The result showed that forest dependency is reducing. There are certain areas that local people used to put the wildlife trap and changes in the process. The study also indicated the areas that need to be prioritized in the protection and management of wildlife resources.

Cynoglossus semilaevis blood biochemical parameters and antioxidant indexes that respond to fishing stress were measured under the influence of different feed taurine levels. With taurine levels of 0%, 0.5%, 1% and 1.5%, 4 groups of test feeds were prepared. After 28 days of feeding. Serum was collected before stress and at 0, 4, 12, 24, 48, 96 h after stress to determine the content of total protein, cholesterol, GPT, GOT, nitric oxide, lysozyme, blood sugar and the activity of glutathione (GSH-PX), superoxide dismutase (SOD), malondialdehyde (MDA) and antioxidant capacity (AOC), the results show: Feeding a feed with a taurine content of 0.5% has a better inhibitory effect on cholesterol and GOT in Cynoglossus semilaevis after fishing stress, and has obvious anti-stress effect on lysozyme and protein. The 0.5% group had the lowest MDA content 12 h after fishing stress. The results suggested that feeding the feed with a taurine content of 0.5%, the Cynoglossus semilaevis blood biochemical parameters and antioxidant indexes to fishing stress has a better response.

Relational Systems Thinking
Authors: Goodchild Melanie
Published: April 2021

We explore the notion of the need to decolonize systems thinking and awareness.  Taking a specifically Indigenous approach to both knowledge creation and knowledge sharing, we look at awareness-based systems change via a Haudenosaunee (Mohawk) two-row visual code.  The authors explore the sacred space between Indigenous and non-Indigenous ways of thinking and knowing, to identify pathways for peaceful co-existence of epistemologies.  Based on conversations with Haudenosaunee elders and Western systems thinkers, along with data from a DoTS webinar, we identify cross-cultural dialogues as a doorway to healing, to transformation and to spiritual understanding.  A reconnection with Mother Earth and with each other is fundamental to disrupting global patterns of trauma and mass corrosion of the spirit.

ALFABETIZAÇÃO E LETRAMENTO NA EDUCAÇÃO INFANTIL: UMA PRÁTICA PEDAGÓGICA DE QUALIDADE
Authors: Marques Dourado Mendes Henrique , Carlos Soares Jean , Roque Sobrinho Mendes Nilza
Published: April 2021

Atualmente nas escolas do Brasil, encontramos um grande problema ao se tratar da precariedade da alfabetização, pois se percebe que muitas pessoas já escolarizadas são consideradas analfabetas funcionais, e que não são capazes de compreenderem o que leem. Entretanto, através da realidade encontrada nas escolas, é fundamental que os professores possam compreender o que é alfabetização e o que é letramento, para assim poderem desenvolver melhor a sua prática pedagógica, sempre visando uma alfabetização significativa.  (MOREIRA, 1993) Logo, o presente texto é resultado de uma pesquisa bibliográfica sobre alfabetização, e um dos principais objetivos é expressar os significados do processo de alfabetização e do processo de letramento, procurando explicitar a especificidade de cada um e a importância da conciliação entre ambos, além de propor uma reflexão entre teoria e prática educacional de se alfabetizar letrando. A Alfabetização e o Letramento caminham juntos, e considera-se um repensar da aquisição da língua escrita, baseado no alfabetizar letrando, que não deve ser trabalhado de maneira independente na realidade da Educação Infantil, já que é fundamental para a vida, a formação e o desenvolvimento do ser humano, em qualquer idade.  (GARCIA, 1998)
