Some Statistics in Polar Coordinate System with Uniform Angles
Authors: KESEMEN Orhan , TİRYAKİ Buğra Kaan , TEZEL Özge , PAK Ayşe
Published: June 2020

In this study, some bivariate distribution functions are defined in the polar coordinate system and random numbers are generated from these distribution functions. In these definitions, the angular change of the probability density function is taken as constant, and the distance change is performed based on the univariate probability density function. Also, the chi-square goodness-of-fit test is proposed for random numbers generated in the polar coordinates. Four different distribution functions are selected to evaluate the success of the proposed chi-square goodness of fit test for polar distribution functions. Lastly, the validity and the success of the proposed method is shown in the simulation study and the real-life example.

Authors: KARA Merve , TOUAFEK Nouressedat , YAZLİK Yasin
Published: June 2020

We show that the
three-dimensional system of difference equationsx_{n+1}=\frac{ax_{n}z_{n-1}}{z_{n}-\beta}+\gamma,  y_{n+1}=\frac{by_{n}x_{n-1}}{x_{n}-\gamma}+\alpha, z_{n+1}=\frac{cz_{n}y_{n-1}}{y_{n}-\alpha}+\beta,

where the parameters a,b,x, \alpha, \beta, \gamma  and the initial
conditions x_{-i}, y_{-i}, i\in\{0,1\}  are non-zero real
numbers, can be solved. Using the obtained formulas, we determine the asymptotic
behavior of solutions and give conditions for which periodic solutions exists.
Some numerical examples are given to demonstrate the theoretical results.
Joy and Sadness in Spiritual Life According to St. Ignatius of Loyola: A Hermeneutic Study
Authors: Homa Tomasz
Published: June 2020

The purpose of this paper is to attempt to interpret human emotionality as expressed in the experiences of joy and sadness, in view of the precepts of one of the schools of Christian spirituality: Ignatius Loyola’s teachings (1491– 1556). According to this current of spiritual philosophy, which draws on the centuries-old experience of the biblical and Christian understanding of the emotional dimension of our lives, as well as the experiences and thoughts of Ignatius himself, our emotionality—often experienced as a kind of incom­prehensible “buzz”—may, in reality, constitute equally emotional, legi­ble “speech.” This “speech” becomes understandable when we can properly “read,” that is, recognize and understand, the emotional experiences we expe­rience in this sphere. The article’s reading feeling is a proposal of commonsen­sical–sapiential deciphering of both our emotional and emotional–spiritual experiences and joys and sorrows, as well as analyzing and interpreting them in the search for relevant meanings that they often carry or express.
About Women who “Busied Themselves with Brigandage”: Katarzyna Włodkowa Skrzyńska and Barbara Rusinowska, Forgotten Lady Robbers from the 15th Century
Authors: Stuchlik-Surowiak Beata
Published: June 2020

Historiographic sources contain the memory of two 15th-century female rob­bers: Katarzyna Włodkowa Skrzyńska and Barbara Rusinowska. The former was the wife of Włodek from Skrzynów of the Swan coat of arms, who lived in Barwałd Castle in the area of Zator and reigned terror in the whole region. We are concerned here with a peculiar phenomenon, that is, a husband–wife duo of robbers, and the fact that they were both of noble birth only spices up this story. Barbara Rusinowska, who was active in the Świętokrzyskie Moun­tains, was also from a noble family. She attacked manor houses and merchant wagons, and her characteristic trait was her men’s attire. Both bandits were finally captured and executed. The article introduces the life story of these women and compares various (often contradictory) information about their brigandage that has survived in ancient chronicles. In the nineteenth cen­tury, Rusinowska became the heroine of a stage drama written by Aleksander Ładnowski.

MoLaBSS: Server-specific add-on biometric security layer model to enhance the usage of biometrics
Authors: Singh Bhanu Pratap , Singh Nirvisha
Published: June 2020

With high
paced growth in biometrics, and its easy availability to capture various
biometric features, it is emerging as one of the most
valuable technologies for multifactor authentication to verify a user’s
identity, for data security. Organizations
encourage their members to use biometrics, but they
are hesitant to use due to perceived security risks. Because of its low usage
rate, many medium and small segment organizations find it unfeasible to deploy
robust biometric systems. We propose a “server-specific add-on biometric security
layer model,” to enhance confidence in the usage of biometrics. We tested this
model via a biometric mobile app, and the survey showed a favorable response of
80%. The innovative mobile app was tested for its usability and got a score of
more than 71%. For test tool reliability, we examined the equal error rate
(EER) of the app and got a reasonably low score of 6%. The results show a good
potential of this framework to enhance users’ confidence-level in the usage of biometrics.
Higher usage rates may make deployment of biometrics more cost-effective for
many organizations to decrease their information
security risk.
Applying Deep-Learning-Based Computer Vision to Wireless Communications: Methodologies,Opportunities, and Challenges
Authors: Tian Yu , pan Gaofeng , Alouini Mohamed-Slim
Published: June 2020

Deep learning (DL) has seen great success in the computer vision (CV) field, and related techniques have been used in security, healthcare, remote sensing, and many other fields. As a parallel development, visual data has become universal in daily life, easily generated by ubiquitous low-cost cameras. Therefore, exploring DL-based CV may yield useful information about objects, such as their number, locations, distribution, motion, etc. Intuitively, DL-based CV can also facilitate and improve the designs of wireless communications, especially in dynamic network scenarios. However, so far, such work is rare in the literature. The primary purpose of this article, then, is to introduce ideas about applying DL-based CV in wireless communications to bring some novel degrees of freedom to both theoretical research and engineering applications. To illustrate how DL-based CV can be applied in wireless communications, an example of using a DL-based CV with a millimeter-wave (mmWave) system is given to realize optimal mmWave multiple-input and multiple-output (MIMO) beamforming in mobile scenarios. In this example, we propose a framework to predict future beam indices from previously observed beam indices and images of street views using ResNet, 3-dimensional ResNext, and a long short-term memory network. The experimental results show that our frameworks achieve much higher accuracy than the baseline method, and that visual data can significantly improve the performance of the MIMO beamforming system. Finally, we discuss the opportunities and challenges of applying DL-based CV in wireless communications.
When Social Support Fits into your Luggage: Online Support Seeking and its Effects on the Traditional Study Abroad Experience
Authors: Mikal Jude
Published: June 2020

In a study abroad context, the maintenance of dual on and offline personas provides students with the opportunity to demolish communication barriers with the home culture created by geographic distance. Conversely, online communication may help bring down communication barriers created by linguistic and cultural differences, providing students with exciting opportunities for face-to-face social interaction with host nationals. Yet, very little is known about how students are using the Internet in the development or maintenance of social support networks during study abroad. The goal of the present research project is to understand how Internet-mediated support complements, supplements or supplants traditional support seeking and how online support seeking leads to changes in the traditional study abroad experience. In this article,  I will present relevant literature on the subjects of acculturative stress, social coping, and Internet-mediated social support in order to ground the research question and study findings.
The Impact of Cultural Intelligence and Psychological Hardiness on Homesickness among Study Abroad Students
Authors: Harrison J. Kline , Brower Holly H.
Published: June 2020

Because of the growth and impact of study abroad experiences, it is important to identify and evaluate factors contributing to students’ success. Unfortunately, a survey of leading U.S. study abroad institutions found that 96% of assessment instruments only gauged students’ satisfaction as the single measurement of success (Berg, 2003). In contrast, the literature on international job assignments identifies psychological adjustment as a vital construct underlying the success of expatriate employee experiences (Selmer & Leung, 2003). Furthermore, personality characteristics or stable personal traits are considered among the most important factors affecting the psychological adjustment of expatriate employees, and thus their success (Huang, Chi & Lawler, 2005; Jassawalla, Truglia, & Garvey, 2004). Two of these traits that are especially appropriate in the study of successful cross-cultural adjustment are cultural intelligence and psychological hardiness. This article presents a study about these constructs and presents a rationale for predictions about their impact on successful psychological adjustment for study abroad participants.
Meta-travel: A critical inquiry into a China Study Tour
Authors: Riggan Jennifer , Gwak S. Sonya , Lesnick Joy , Jackson Kara , Olitsky Stacey
Published: June 2020

This paper questions whether participants on short-term study tours typically allow themselves and their understandings about the world to be transformed by their experiences or if these brief trips only serve to reify and legitimize preconceived notions and stereotypes about the world. Based on an analysis of U.S. graduate students’ experiences on a trip to China, we argue that short-term study tours have the potential to provide a valuable opportunity for participants to deepen their understanding of themselves and their role in the world. However, they can only do so if a critical reflection component is incorporated in the study tour. Specifically, short-term study travel can help participants understand the situated and shifting nature of their identities as students and travelers. It can also deepen their awareness of how they are positioned globally as students of a U.S. based institution, and explore how positionality, identity, and stereotypes shape their worldview during study tours. By engaging in an intentional, critical reflection process, we argue that participants can experience deeper emotional and intellectual transformation during short-term study tours. We use the case of a study tour to China to propose a framework for reflection during short-term study travel that we call “meta-travel.”
The High Impact of Education Abroad: College Students’ Engagement in International Experiences and the Development of Intercultural Competencies
Authors: Stebleton Michael J. , Soria Krista M. , Cherney Blythe T.
Published: June 2020

This study attempts to discover whether the different study abroad activities in which students participate yield different outcomes for the development of students’ global and intercultural competencies. The five travel and study abroad measures analyzed include experiences in a university study abroad program; study abroad program affiliated with another college or university; travel abroad for cross-cultural experiences or informal education; travel abroad for a service-learning, volunteer, or work experience; and travel abroad for recreation.  This study explores the research question at a single institution so as to isolate students’ experiences as they may occur within a single institutional context.

У статті розкривається творчий та педагогічний потенціал видатного педагога, професора кафедри народних інструментів Донецької консерваторії, засновника донецької баянно-акордеонної школи, фундатора кафедри народних інструментів цієї консерваторії, який взяв активну участь у її становленні та формуванні, «Відмінника освіти» В.М. Протопопова.Наголошується на унікальності його постаті, яка в період сьогодення належить до несправедливо забутих, попри неоціненний вклад, як у сценічний розвиток інструментів (баян-акордеон), так і в базу методичних розробок викладання гри на цих інструментах. Серед випускників педагога чимало відомих у культурно-музичному світі людей, про яких ми можемо знайти набагато більше інформації, ніж безпосередньо про їхнього вчителя та наставника. Автором статті було виконано низку завдань для розкриття багатогранності і неповторності особистості великого майстра баянно-акордеонного мистецтва – Віктора Миколайовича. На основі історичних матеріалів, спогадів учнів та друзів про культурне надбання, методичних праць та результатів педагогічної діяльності висвітлено цю видатну постать як знаного майстра баянно-акордеонного мистецтва.Уроки Віктора Протопопова були справжніми майстер-класами для всіх, хто був присутній в аудиторії та бажав вслухатись у кожне слово педагога, отримати поради цього майстра, що були цінними для всіх студентів консерваторії. Віктор Миколайович був для своїх студентів викладачем, майстром, наставником і просто хорошим другом. Паралельно з педагогічною діяльністю В. Протопопов здвйснював активну виконавську діяльність у багатьох ансамблях, був учасником колективів (ансамблі та оркестри народних інструментів) та безпосередньо їх керівником.Як виконавець цей видатний музикант володів професійною технікою, виявляв особливу схильність до ансамблевого виконання. У його концертних програмах завжди були твори різних епох та стилів, він мав багато записів на обласному радіо та телебаченні.В.М. Протопопов проводив активну науково-методичну роботу. Він написав понад 90 навчально-методичних і творчих робіт (біля 50 друкованих аркушів, багато з яких надруковані). Серед них: перекладення музичних творів для ансамблів баяністів, концертні обробки народних мелодій, оригінальні п’єси для баяна-акордеона. Його науково-методичні роботи відрізняються сучасними поглядами з методики гри на баяні-акордеоні. В.М.

Drug Metabolites: General Features and Most Applicable Analytical Methods of Studies
Authors: Batista Pedro H. J. , Quilles Jr José C.
Published: June 2020

Drug discovery and development is a multi and interdisciplinary process that includes chemistry and biology understanding. Though, drug discovery is an expensive and time-consuming process, promoting the lack of new drugs approval in recent years. In general, most of the drugs are established based on a macromolecular target, which is vital to disease progression. However, in many cases, the mechanism of drug-macromolecular target interaction is complex and not understood. All this missed information is strongly dependent on the physicalal-chemical stability and behavior of the molecule inside the cell, which is correlated to its metabolism resistance and entrance into the cell through the cellular membrane, respectively. Thus, bioanalysis often provides enough data about these molecular characteristics and helps to figure out new information about these subjects. In this context, the study of the metabolism of parental compound plays a key role in bioanalysis and, consequently in drug discovery. For a long time, the study of metabolism represented a huge challenge in medicinal chemistry, but with the technological advancements, many powerful techniques were developed and, currently, the metabolomics fields are essential steps in the process of discovering a new drug. Herein, we briefly discuss the biological aspects of the drug metabolism, focusing on the most used analytical tools to better understand the metabolite generation, and consequently, their chemical and biological characteristics.
Parents’ Economic Status and Academic Performance in Public Primary Day Schools in Multinational Tea Estates Kericho County, Kenya
Authors: Kiruy Francis , Manduku Joshua , Ngeno Viviline
Published: June 2020

Dynamism in family finances, family type, and style of parenting has been associated with the well-being of a child. Poor performance usually indicates that some factors may be of the cause other than those found in schools since all schools in the republic of Kenya are given funds, teachers, and other resources equally. The purpose of this study is to investigate the influence of parents’ economic status and pupils’ academic performance in public primary tea estate schools in Kericho County. The research utilised social learning theory to bring the conceptualisation of the role of parents and family in enhancing academic performance. The study adopted a correlation research design. The study targeted 336 standards seven and eight pupils and 55 parent association members, 5 deputy headteachers and 5 headteachers from 5 schools from the selected schools in the tea estates in Kericho County. A sample population of 101 pupils, 55 parent Association members, 5 parents as well 5 headteachers, and 5 deputy headteachers were obtained using a stratified random sampling technique. The sampled 101 pupils were given questionnaires, while 55 parents association members, 5 headteachers, and 5 deputy headteachers were interviewed by the researcher. Both questionnaires and interview schedules were used to collect data from the field. Quantitative data were analysed using descriptive statistics where percentages and means were utilised. Pearson product-moment correlation coefficient was used as inferential statistics. Qualitative data were analysed through content analysis.  Financial based problems attributed the highest issues that affect the parents in the estate for over-dependence wages and salaries that can sustain basic needs. Therefore, the study concluded that parent economic status had a significant effect on the pupil’s academic performance. The study recommended that there is a need for the multinational tea estates to consider assisting the children financially in estates through corporate social responsibility.
[3 + 2] Cycloaddition with photogenerated azomethine ylides in β-cyclodextrin
Authors: Sohora Margareta , Mandić Leo , Basarić Nikola
Published: June 2020

Stability constants for the inclusion complexes of cyclohexylphthalimide 2 and adamantylphthalimide 3 with β-cyclodextrin (β-CD) were determined by 1H NMR titration, K = 190 ± 50 M−1, and K = 2600 ± 600 M−1, respectively. Photochemical reactivity of the inclusion complexes 2@β-CD and 3@β-CD was investigated, and we found out that β-CD does not affect the decarboxylation efficiency, while it affects the subsequent photochemical H-abstraction, resulting in different product distribution upon irradiation in the presence of β-CD. The formation of ternary complexes with acrylonitrile (AN) and 2@β-CD or 3@β-CD was also essayed by 1H NMR. Although the formation of such complexes was suggested, stability constants could not be determined. Irradiation of 2@β-CD in the presence of AN in aqueous solution where cycloadduct 7 was formed highly suggests that decarboxylation and [3 + 2] cycloaddition take place in the ternary complex, whereas such a reactivity from bulky adamantane 3 is less likely. This proof of principle that decarboxylation and cycloaddition can be performed in the β-CD cavity has a significant importance for the design of new supramolecular systems for the control of photoreactivity.

A New Estimate for the Orientation of Underlying Heliospheric Magnetic Field Associated with Alfvénic Fluctuations
Authors: Teh W.-L. , Gosling J. T.
Published: June 2020

In the solar wind Alfvénic fluctuations are coupled fluctuations in the transverse components of plasma velocity,

remains nearly constant. Consequently, the fluctuations in the component of

and

along the direction of the underlying magnetic field,

, are always one-sided relative to base values rather than mean values. This paper proposes a new method for estimating

and verifies it using simulation data. The new approach is to find a consistent minimum variance direction of magnetic field for two different data subsets divided by a threshold angle from the original data set. Simulation results show that (1) the direction of

Two events of one-sided Alfvénic fluctuations in the solar wind observed at 0.36 and 1 au, where a small but significant mean appears in the transverse field fluctuation, are demonstrated for the new method. Results show that the new estimate is more radial than

This study provides a first step toward the knowledge of the alien-dominated and co-dominated plant communities present in Italy. The first ever checklist of the alien phytocoenoses described or reported in literature for the Italian territory has been compiled, produced by data-mining in national and local thematic literature. The resulting vegetation-type draft-list has been checked in the light of the most recent syntaxonomic documentation and updated with regards to syntaxonomy and nomenclature, with special reference to the frame proposed in the Italian Vegetation Prodrome. The list includes 27 vascular and one bryophyte vegetation classes, hosting 194 low rank alien-dominated syntaxa. The different vegetation types detected for each syntaxonomic class and macro-vegetation group, defined by physiognomical and ecological attributes, are discussed.
La prise en compte des enjeux environnementaux dans la comptabilité agricole : utopie ou nécessité ?
Authors: Charriot Camille , Vidal Olivier
Published: June 2020

L’agriculture est confrontée à de nombreux enjeux environnementaux. L’article discute de la faisabilité de la mise en œuvre d’une comptabilité sociale et environnementale (CSE) agricole en triple capital en s’appuyant sur une expérimentation. Il apparaît que la CSE agricole permet de révéler l’existence de données que ne mesure pas la comptabilité traditionnelle et de quantifier les bénéfices d’une agriculture respectueuse de la nature. Cependant, elle est perçue par de nombreux exploitants comme source de contraintes contre-productives. L’évaluation des effets sur l’environnement s’avère subjective. Enfin, la CSE manque d’intérêt pratique dans le pilotage opérationnel tourné vers le suivi de la trésorerie. L’expérimentation révèle donc que la CSE peut faire évoluer les mentalités, mais ne peut suffire à faire évoluer les pratiques. Elle rappelle que la comptabilité n’est pas « verte » ou « rouge », mais qu’elle demeure un outil qui accompagne les décisions politiques en permettant leur mise en œuvre.

Cette étude analyse comment la diffusion d’un outil de pilotage de la performance est perturbée dans sa mise en œuvre par l’interaction des logiques gestionnaire et politique. Cette question est abordée en prenant appui sur une expérimentation portée par un Rectorat d’Académie française. L’étude entend contribuer aux travaux sur les facteurs perturbant la mise en œuvre d’outils de pilotage de la performance dans un contexte organisationnel particulier qui est celui des Établissements Publics Locaux d’Enseignement (EPLE). Ce travail met en avant que les rationalités différentes, sous-jacentes à l’interaction des logiques gestionnaire et politique, peuvent conduire à perturber le développement des outils de pilotage de la performance au sein des organisations publiques.
Liberté d’expression et nouvelles théories de la censure
Authors: Roussin Philippe
Published: June 2020

Les définitions de la censure ont fortement évolué au cours des dernières décennies. De nouvelles théories sont apparues, chassant le récit classique du libéralisme politique, celui de l’émancipation conduite à partir des Lumières contre l’oppression, l’obscurantisme, l’esprit victorien. Pour les théories libérales, la censure est une contrainte, un obstacle à l’expression, un frein à l’exercice d’un droit politique. Elle s’impose de l’extérieur à une parole qui, autrement, serait libre. Les nouvelles conceptions de la censure mettent, elles, l’accent sur les structures implicites et sur les formes multiples de la censure sociale . Elles la présentent comme un élément omniprésent de la réalité sociale. L’un des traits communs à ces nouvelles descriptions est la thèse selon laquelle la censure ne serait pas de l’ordre de l’interdit mais plutôt d’une injonction à parler.
Faut-il limiter la liberté d’expression des discours blessants ? Les affaires Slàv et Kanata
Authors: Gauthier Gilles
Published: June 2020

En regard des spectacles Slàv et Kanata , est examinée la question de la justification philosophico-éthique des discours blessants non haineux en comparant les positions divergentes de Jocelyn Maclure et de John Searle se réclamant toutes deux de la théorie des actes de discours. Après avoir fait valoir la justesse de la position de Searle, l’article propose de considérer que le différend entre les deux philosophes résulte d’une distinction fondamentale entre leurs conceptions respectives de l’éthique.
Secret des affaires, lanceurs d’alerte et risques d’autocensure : approche juridique
Authors: Mallet-Poujol Nathalie
Published: June 2020

Avec la loi du 30 juillet 2018 relative à la protection du secret des affaires, tant le périmètre de protection du secret des affaires que le mode de protection des lanceurs d’alerte sont de nature à inciter à l’autocensure, en raison de la conscience des périls encourus. Les craintes peuvent légitimement porter aussi bien sur le risque d’un procès que sur le risque même de perdre ce procès, faute d’être en mesure d’apporter la preuve complète de la poursuite de l’intérêt général et de l’existence de la bonne foi.
La grammaire de l’accessibilité
Authors: Ebersold Serge
Published: June 2020

Ce texte corrèle l’idéal normatif revendiqué par l’impératif d’accessibilité à l’avènement d’un horizon socio-anthropologique capacitaire conduisant à rapporter les difficultés scolaires et sociales à l’inaccessibilité des institutions et, notamment, de l’institution scolaire ou médico-sociale. Il insiste d’abord sur les formes de désencastrement induites par des modes d’analyse qui infèrent les performances individuelles à leurs milieux de réalisation en rapportant les processus d’apprentissage aux réactions cérébrales intervenant dans le traitement de l’information. Il s’intéresse ensuite au système de signes, de symboles et de règles qui, à l’image d’une grammaire, distingue l’accessible de l’inaccessible et préside aux stratégies d’accessibilisation des environnements scolaires. Il corrèle ainsi l’impératif d’accessibilité aux représentations de l’individu mises en avant, aux grilles de lecture de la difficulté scolaire qu’elles portent en elles ainsi qu’aux composantes intervenant dans sa concrétisation.
Une colère étudiante globale ? Analyse comparée des mouvements étudiants du Chili (2011), du Québec (2012) et de Hong-Kong (2014)
Authors: Van de Velde Cécile
Published: June 2020

Assiste-t-on à la montée d’une colère étudiante globale, née dans le sillage de politiques d’austérité et de réformes éducatives mondialisées ? Pour répondre, l’article s’appuie sur une comparaison des revendications portées au sein de trois mouvements étudiants post-2008 : celui de Santiago du Chili (2011-2012), le Printemps Érable à Montréal (2012) et la Révolution des Parapluies à Hong-Kong (2014). Le dispositif comparatif repose sur l’analyse statistique et qualitative des mots de la colère, c’est-à-dire des slogans, écrits, posters, recueillis de façon directe au sein de chacune des contestations (n=1100). La comparaison vise à identifier les différents répertoires mobilisés, mais aussi les problématiques communes entre ces trois mouvements. L’article montre qu’au-delà de leurs contrastes, les discours se rejoignent sur une même trame fondamentale articulant trois questions de fond, reliées entre elles : la valeur de l’éducation, l’injustice de la dette et le renouveau démocratique.
Marius Maximus, gouverneur de la Gaule Belgique, haut fonctionnaire et historien
Authors: Hoët-Van Cauwenberghe Christine
Published: June 2020

Marius Maximus est un haut fonctionnaire romain ayant effectué l’essentiel de sa carrière sénatoriale à la fin de la dynastie antonine et surtout sous la dynastie des empereurs sévères. La documentation épigraphique nous renseigne bien sur ce personnage qui fut gouverneur de Gaule Belgique avant d’atteindre le sommet du cursus honorum . Contemporain de Cassius Dion, dont on connaît le récit Histoire romaine , il semble pouvoir être identifié à l’historien Marius Maximus cité par les sources tardives comme l’auteur de biographies impériales.
Divin marquis. Le général de Galliffet demande la grâce de Dreyfus, 13 septembre 1899
Authors: Bouthillon Fabrice
Published: June 2020

Le général de Galliffet a surtout laissé la réputation d’un sabreur, spécialement cruel dans la répression de la Commune. Comme ministre de la Guerre du gouvernement Waldeck-Rousseau, c’est pourtant lui qui, avec une intelligence stratégique remarquable, a formulé, dans une lettre au président du Conseil à l’issue de la seconde condamnation de Dreyfus à Rennes, dont ce texte propose une lecture attentive, les conditions de sortie de l’Affaire : la grâce pour Dreyfus, combinée à l’amnistie des officiers qui avaient machiné sa perte. L’historiographie française se garde bien de le dire, mais on peut considérer cet ultimatum discret de l’Armée à la République comme une forme atténuée de pronunciamiento .
Les préfets du Pas-de-Calais et la défense du cadre départemental au milieu des années 1940
Authors: Roger Philippe
Published: June 2020

Sous l’effet de la seconde guerre mondiale, les cadres territoriaux de la vie politique et de l’administration, qui avaient assez peu évolué depuis le milieu des années 1880, sont brutalement remis en cause. Un échelon régional est créé et de profondes modifications du cadre départemental sont parfois envisagées. Ces bouleversements inquiètent beaucoup d’hommes politiques mais aussi de nombreux responsables administratifs. Les préfets Marcel Lanquetin et Georges Phalempin prennent donc la défense du cadre départemental, dont ils rappellent l’ancienneté, qui en fait une structure très largement acceptée par les populations, et qu’ils estiment constituer un espace parfaitement adapté aux tâches administratives. La coexistence des départements et des régions apparaît en revanche difficile, le précédent du régime de Vichy semblant montrer l’existence d’un risque de confusion entre les différents niveaux administratifs.
Jalons pour une histoire politique du territoire : les politiques de régionalisation dans le Nord – Pas-de-Calais au temps de la République gaullienne
Authors: Tellier Thibault
Published: June 2020

Il y a soixante ans, le retour au pouvoir de Charles de Gaulle était placé sous le signe de la refonte des institutions ainsi que de la modernisation des structures politico-administratives. Le décret de 1964 qui institue les commissions de développement économiques régionales et les préfets de région marque la volonté de l’État de faire désormais de l’échelon régional le fer de lance du développement économique national. Plus largement, il s’agit pour le pouvoir gaulliste d’écrire une nouvelle page de l’histoire politique territoriale de la France. De ce point de vue, l’étude de la régionalisation dans le Nord – Pas-de-Calais illustre la manière dont la réforme régionale s’est aussi saisie de la question de la fin du modèle industriel classique et de son remplacement par de nouvelles formes d’économies adaptées au territoire nordiste.
L’autonomie journalistique face aux chiffres. L’interprétation des métriques dans deux entreprises de presse
Authors: Grossi Valentina
Published: June 2020

Les outils d’évaluation chiffrée, de plus en plus répandus dans les entreprises de presse, sont souvent accusés d’entraîner une standardisation de l’évaluation et une érosion de l’autonomie journalistique. Cependant, une ethnographie comparée dans deux rédactions françaises permet de réfuter l’idée selon laquelle les métriques auraient des effets univoques. L’analyse de l’organisation du travail est centrale et permet d’expliquer des dynamiques d’appropriation contrastées : si des organisations fondées sur la collégialité encouragent les professionnels à mobiliser les chiffres en faisant preuve d’une certaine prudence, un contexte de renforcement du pouvoir hiérarchique et d’individualisation du travail tend à en faire des outils de standardisation et d’encadrement managérial.
Ce que les professionnels font aux chiffres. Le cas de l’accompagnement d’un opérateur face à l’accès au logement social francilien
Authors: Legros Baptiste
Published: June 2020

À partir d’une enquête ethnographique menée au sein d’un opérateur social francilien, cet article propose d’analyser les usages de données quantitatives par les professionnels en repartant de la notion d’obligation chez Durkheim. Il s’attache tout d’abord à rendre visibles les résistances et les subversions réalisées à l’égard des chiffres, qui ne parviennent pas à s’imposer d’eux-mêmes sur le jugement et les décisions des professionnels. Pour comprendre alors les raisons de ces résistances et pourquoi les acteurs s’obligent à mobiliser ou non ces chiffres, il entend dans un second temps saisir la dissociation morale qui s’est réalisée avec les changements organisationnels de l’opérateur. Bien que concurrentes, ces deux morales ne sont cependant pas figées et attachées exclusivement à certaines pratiques professionnelles, l’une pouvant s’imposer à l’autre lorsque les acteurs considèrent que leurs actions entravent leur solidarité ou le bien de la personne accompagnée.
« Risques » et « radicalisation ». Critiques savantes et professionnelles d’un outil d’évaluation criminologique
Authors: Chantraine Gilles , Scheer David
Published: June 2020

L’outil vera -2 est un instrument d’évaluation des risques spécifiquement conçu pour évaluer les risques liés au terrorisme et à l’extrémisme violent. Cet article vise à éclairer la diversité des critiques des professionnels amenés à l’utiliser quotidiennement dans les prisons françaises, au sein des « quartiers d’évaluation de radicalisation » ( qer ). Outre cet éclairage empirique relatif au processus d’évaluation des personnes considérées comme « radicalisées » dans les prisons, l’enjeu de cette contribution est de montrer comment ces critiques s’expliquent par le positionnement et l’identité professionnelle des acteurs en présence (psychologues, éducateurs, conseillers pénitentiaires d’insertion et de probation) et, simultanément, comment elles entrent en résonnance avec les critiques plus globales, académiques notamment, du tournant néo-libéral des politiques pénales
Des chiffres en bataille. Évaluer la lutte contre « l’économie souterraine »
Authors: Guenot Marion
Published: June 2020

Cet article traite de la place centrale de l’évaluation chiffrée dans l’évolution de l’activité des Groupes d’intervention régionaux ( gir ) de la police nationale. Ces unités rassemblent des policiers, des gendarmes, des inspecteurs de la Douane, des Impôts et du recouvrement de l’Urssaf. Dans un premier temps, on verra comment les agents nommés dans les gir ont élaboré des indicateurs chiffrés pour légitimer leur choix de cibler en priorité des délinquants issus du « crime organisé » ou des milieux aisés. Dans un second temps, les pratiques d’auto-évaluation seront décrites en articulant l’observation du travail avec l’insécurité professionnelle, en particulier des douaniers, sur fond d’injonctions au résultat et de réduction des effectifs.
