Low-frequency Flux Density Measurements and Pulsars with GHz-peaked Spectra
Authors: Kijak J. , Basu R. , Lewandowski W. , Rożko K. 
Published: December 2021

Abstract
We have estimated flux densities of several pulsars from radio interferometric observations mainly at 325 MHz using the Giant Metrewave Radio Telescope. The new observations allowed us to update the spectral nature of the observed pulsars, and in six sources we identified relatively high frequency turnovers, which can be classified as new GHz-peaked spectrum (GPS) pulsars. For such objects the turnover in the spectrum is most likely caused by absorption in the immediate vicinity of the pulsar (or in the interstellar medium). We modeled the turnover spectra using the thermal free–free absorption model and the physical parameters obtained from the fits enabled us to identify the environments that could potentially be responsible for the observed absorption, such as pulsar wind nebulae, supernova remnant nebulae or H ii regions. The discovery of 6 new GPS pulsars brings the total number of such objects to 33 and we discuss the properties of the entire sample.

Apprentissage dual de jeunes étrangers – une réponse à la pénurie de main-d’œuvre spécialisée ?
Authors: Lestrade Brigitte 
Published: December 2021

La pénurie de personnel qualifié touche tous les secteurs d’activité en Allemagne depuis des années, parce que les jeunes s’intéressent de moins en moins à la formation duale, qu’elle soit dispensée dans l’industrie ou l’artisanat. Depuis quelques années, le gouvernement allemand encourage la venue de jeunes étrangers susceptibles de combler le manque d’apprentis, notamment par la loi sur l’immigration de travailleurs qualifiés de 2020. Toutefois, les entreprises allemandes s’étaient mises à rechercher de jeunes apprentis étrangers déjà avant ce changement, comme en atteste le triplement de leur nombre en dix ans. Or, les obstacles sont nombreux : hormis les barrières linguistiques et culturelles, les entreprises, notamment les PME/PMI craignent des risquent tels que les fausses identités, voire la radicalisation. L’accroissement important de leur nombre, notamment depuis l’arrivée massive des migrants il y a quelques années, montre que les employeurs ont su surmonter leurs réticences, en attendant le coup de frein en raison de la pandémie.
La mondialisation, l’i-zation de la société et le Covid-19
Authors: Possamaï Adam 
Published: December 2021

S’il n’existe qu’une planète terre, le concept de mondialisation en revanche n’est pas monolithique et évolue en fonction de changements sociaux, culturels, et économiques. La mondialisation du XXI e siècle diffère du tout au tout de celle du XX e . Bien que l’interdépendance globale économique et numérique soit plus forte que dans le passé, de nouvelles fractures politiques et populistes s’opèrent au niveau national. Cet article mobilise le récent concept d’i-zation de la société, en tant que nouveau facteur de la McDonaldization de la société, pour analyser les récents avancements et impacts du capitalisme numérique sur la mondialisation. Grâce aux smartphones et autres technologies de pointe, nous entrons dans un nouveau processus de compréhension de la mondialisation qui s’accélère de plus en plus sous l’effet des mesures non pharmacologiques mises en place pour lutter contre le Covid-19.
Bourdonnements et stridences dans les Pensées de Pascal
Authors: Gatier Aline 
Published: December 2021

Bourdonnements, grincements : des sons dissipent notre attention, montre Pascal. Mais les perturbations sonores ne sont pas seulement des métaphores dans les Pensées : elles entrent aussi dans la composition de fragments construits comme des pièces musicales, selon le principe paulinien de la Fides ex auditu , conversion par l’audition. Comme un compositeur, Pascal cherche à nous toucher par des tensions, des dissonances, voire des stridences. Écoutons-les…
Les Dépossédés (1974)
Authors: Morel Darleux Corinne 
Published: December 2021

Ursula Kroeber Le Guin (1929-2018) a écrit de nombreux ouvrages salués par ses pairs, par la critique (Prix Hugo, Nebula, etc.) et par le public. Malgré la puissance de son œuvre et ses qualités littéraires, l’audience de ses livres a connu une éclipse. Ceux-ci sont aujourd’hui redécouverts et plébiscités autant par la communauté des lecteurs·trices et des auteur·trices de science-fiction que par les militant·es. Les textes d’Ursula K. Le Guin, notamment les plus connus comme Les Dépossédés (Robert Laffont, 1975) et La Main gauche de la nuit (Robert Laffont, 1971), offrent à celles et ceux qui s’y plongent des univers oniriques mais profondément politiques. Le Guin y explore différents thèmes en –isme : l’anarchisme et le communisme, l’écologisme et le féminisme, ou encore le colonialisme. Dans ce mini-dossier consacré à quelques livres de cette anthropologue, créatrice de mondes et d’utopies, Mouvements a demandé à plusieurs autrices et auteurs de SF de présenter leur regard sur un livre d’Ursula K. Le Guin.
Dans les paradoxes des utopies de science-fiction
Authors: Curval Philippe , Kyrou Ariel 
Published: December 2021

Dans Le Paquebot immobile , sorti fin 2020, Philippe Curval imagine une utopie anarchiste sur une île artificielle fabriquée à partir de déchets plastiques. Auteur d’une quarantaine de romans depuis Les Fleurs de Vénus , publié en 1960, jusqu’à Idem’s , paru chez La Volte le 14 octobre 2021, ce grand romancier nous parle de sa vision de l’utopie, mais aussi des utopies que l’on trouve dans la littérature de science-fiction, de H. G. Wells à Ursula K. Le Guin.
Élisée Reclus sans l’utopie
Authors: Pelletier Philippe 
Published: December 2021

D’Élisée Reclus on connaît le militantisme anarchiste, les engagements féministes, les écrits politiques, le travail scientifique du géographe. On oublie qu’une partie de son combat a consisté à contester les idées reçues véhiculées autour de l’anarchisme, idées souvent exprimées sous la forme de critiques qui voyaient (et voient encore) dans ce courant éthique et politique la traduction d’une envie de scission, le désir d’échapper à la réalité par le refuge dans de petites communautés autogérées. Resituant les engagements de Reclus dans le contexte des discussions au sein de la gauche à la fin du XIX e siècle sur les formes à donner à l’émancipation, cet article explique pourquoi Reclus s’est toujours tenu à bonne distance de la tentation utopique.
Learning to be a “Stay-at-home Father”
Authors: Chatot Myriam 
Published: December 2021

Les recherches menées sur les parents en congé parental, principalement des mères, ont souligné les effets socialisateurs de ce dispositif pour les bénéficiaires. À partir d’une enquête menée auprès de trente-huit pères en congé parental à plein temps en France, l’objectif de cet article est de prolonger ces recherches par l’étude de cette population minoritaire, afin de mettre en évidence les compétences et les savoirs acquis dans le cadre du congé parental, et comment cette socialisation temporelle s’articule avec les conditions d’exercice du congé et les socialisations antérieures de ces hommes. Après avoir distingué plusieurs catégories de pères en fonction de leur rapport à la maîtrise du temps durant le congé parental – les « maîtres de maison », les pères « déviants » et les pères « débordés » –, différentes aptitudes et connaissances temporelles que les pères déclarent avoir acquises au cours de ce congé seront investiguées, notamment les savoirs liés au rythme propre de l’enfant et à la gestion de ses sollicitations et les compétences organisationnelles nécessaires à la prise en charge parallèle du travail parental et domestique.
French History of Parental Leave Policies
Authors: Collombet Catherine 
Published: December 2021

L’objectif d’égalité de genre n’a pas été, loin sans faut, au cœur de l’histoire des congés parentaux et de leur rémunération en France et c’est dans le temps long, par étapes successives, que la politique de congés parentaux s’est extraite de l’empreinte de ses origines. Elle s’est d’abord organisée, jusqu’en 1977, autour de l’allocation de salaire unique (ASU), forme de « salaire maternel » destiné à permettre aux mères de se retirer de manière permanente du marché du travail. Le déclin de l’ASU puis sa suppression ont donné lieu à une nouvelle période, pendant laquelle les dispositifs ont été ouverts dans les mêmes conditions au père et à la mère. La dernière phase, qui n’est pas achevée, est celle de la recherche d’un partage effectif du congé entre les deux parents.
Quand l’air reprend son souffle
Authors: Brioude Zoé 
Published: December 2021

Sur le plateau de Philippe Quesne, hiérarchies humaines et linéarité de l’action sont déstructurées : l’anthropocentrisme ne règne plus et le monde scénographié existe pour lui-même. Les choses et les corps peuvent libérer des extases, pour former ce que Böhme a appelé des atmosphères esthétiques. Ni objectives, ni subjectives, elles brouillent les frontières entre sujets et objets, actants et actés, et ouvrent à un nouveau matérialisme qui prend résolument le parti de la matière, contre le matérialisme économique anthropocentré, dans le contexte de la crise écologique. Dans cette ontologie reconfigurée, les personnages d’idiots tout à fait rossetiens qui peuplent le Vivarium Studio empruntent à l’air, élément favori de Philippe Quesne, l’allégresse qui leur permet d’approcher au plus près le réel et sa vérité tragique : il n’y a et n’y aura que cela, le réel. Un auteur de science-fiction donne le ton : « Le futur qui nous attend est celui que nous créons. Vous feriez mieux d’y croire. ». Le compromis paradoxal entre approche métaphysique et approche matérialiste du réel, que nous nommons « métaphysique du sensible », est le symptôme d’un art qui a renoncé à la transcendance et se met au diapason du crépuscule pour lutter contre la fin du monde en douceur.

Authors: Zeeshan Mohd , Srishti  , Kumari Sarita , Pothamsetty Yogitha , Verma Kiran , Dubey Tushar 
Published: December 2021

Background:
Although there are many drugs which are used for topical therapy in recurrent aphthous stomatitis (RAS) patients, there are few clinical trials that have used tetracycline and amlexanox.

Aim and Objectives:
To evaluated the therapeutic efficacy of topical tetracycline and amlexanox.

Materials and Methods:
Here in this study we divided the RAS patients into two groups in each group alternative selection was done. Patients of 1st Group received topical application of tetracycline crushed tablets with denture adhesive and few drops of saline solution on each alternative day visit. Same as Group 2nd subject received amlexanox. Treatment response was assessed by measuring pain reduction, photographic record, ulcer duration, and adhesive retention time.

Results:
Amlexanox oral paste show more efficacy in comparision of topical tetracycline in the treatment of recurrent minor aphthous ulcers.

Conculsion:
Amlexanox is more effective in comparison of tetracycline.

Published: December 2021

Objective: The aim of the study to show the relation of T cells in placental villous fragments with FOXP3,JAK1 and STAT5 receptors in different conditions such as GDM, PE and IUGR placental tissues.
Methods: Specimens of ten(10) diabetic placentas, ten(10) preeclamptic, ten(10) intrauterine growth restricted placentas and ten(10) control placentas were collected by systematic uniform random sampling. Immunohistochemical detections of FOXP3, JAK1 and STAT5 were performed in histological sections for each group’s placental tissue. The H-score value was derived for each specimen by calculating the sum of the percentage of syncytiotrophoblast and syncytial nodes in placenta and intervillus area. They were categorized by intensity of staining, multiplied by its respective score.
Results: FOXP3, JAK1 and STAT5 immunoreactivity comparisons are shown in four groups of placentas. FOXP3 immunoreactions significantly increase in GDM group. JAK1 and STAT5 immunoreactions significantly decrease in PE group. STAT5 immunoreactivity was detected crucially increase in GDM group.
Discussion: The results showed that in different conditions such as PE,GDM and IUGR, T cells in placental villous fragments have relation with FOXP3,JAK1 and STAT5 receptors and that FOXP3 can inactivate the PE and IUGR in the placental tissue. We have also confirmed as other studies that JAK-STAT pathway plays important role in PE,IUGR and GDM placental tissue.

Published: December 2021

Objective: To evaluate vaginal birth safety by comparing the results of cesarean birth in twin pregnancies with the first twin in vertex presentation.
Material and methods: A retrospective cohort study of vertex-presenting twin pregnancies between 32 weeks 0 days and 38 weeks 6 days of gestation was conducted at our hospital from January 2013 to December 2014. The study population was divided according to the mode of birth. The primary outcome was early neonatal mortality, and secondary outcomes related to maternal and perinatal clinical characteristics were analysed between the groups.
Results: Of 45,166 births, 1.92% (n = 869) were twin pregnancies. Of the 295 pregnancies meeting the study criteria, 30.16% (n = 89) were in the vaginal birth group, while the remaining 69.84% (n = 206) were in the cesarean birth group. In the vaginal birth group, all the first twins were delivered via vaginal birth, while among the second twins, 82.03% (n = 73) were delivered via vaginal birth, and the remaining 17.97% (n = 16) were delivered via cesarean birth. In the vaginal birth group, the early neonatal mortality rate was 22.4‰ (n = 2), and it was 9.7‰ (n = 2) in the cesarean birth group. All of the deaths occurred in pregnancies under 37 weeks of gestation.
Conclusion: The neonatal outcomes between the vaginal birth and cesarean birth groups were similar in term pregnancies with the first in twin vertex presentation, whereas adverse neonatal outcomes were increased in the vaginal birth group in preterm second twin pregnancies.

Antik dönemde yerleşim yerlerinin seçiminde belirleyici unsurlar günümüzdeki yerleşim yerlerinin seçiminde de öncülük etmişlerdir. Bunların en başında; su, toprak, coğrafi konum, tarihi doğal yollar ve maden yatakları gelmektedir. Yerleşmelerin seçiminde öncelikli olarak su kaynaklarının olması, verimli ırmak vadileri ve denize sınır faktörü öncelikli tercih sebeplerinden olmuştur. Giresun coğrafyası hemen hemen tüm bu özellikleri barındırmaktadır.
Doğu Karadeniz Bölgesi önemli akarsu ağlarına ve limanlara sahiptir. Bunun yanında Orta Karadeniz ile Kafkasya Bölgesi arasında bir köprü görevi üstlenmiştir. Bölge en erken devirlerinden itibaren geçiş noktası durumunda olup çevre kültürler ile ilişkidedir. Giresun ili kıyı kesimi ile dağlık kesimde yaptığımız arkeolojik araştırmalar ile elde edilen buluntular sayesinde bölgenin Hellenistik ve Roma Dönemleri kültürlerine ve yerleşim arkeolojisine dayalı önemli bilgilere ulaştık. Bu araştırmada; yerleşim yerlerinde tespit edilen seramiklerin yapısal özellikleri diğer bölgelerle arasındaki benzerlikler ve farklılar ortaya çıkarılmıştır. Giresun ve çevresi erken dönemlerden itibaren iskân edilmesine rağmen, genel anlamda bu bölgedeki araştırmalar daha yeni sayılabilir niteliktedir. Topografya yapısı ve bitki örtüsü bu gecikmenin en önemli nedenlerindendir.
Replacing place in planning history
Authors: Castello Lineu 
Published: December 2021

Variations are due to happen in the course of Planning History, though there has been an unusual outburst of changes in recent times. Two factors seem to be at the outset of these changes: the crucial growth of global urbanization; and the actual tendency for cities presenting a complex of ‘place’ centralities. Undoubtedly, central to alterations in Planning History are the special conditions of contemporary society, with almost 80% of whose members living in urbanized environments. But next to it comes the extraordinary increase in the production of newly invented ‘places’ under the most diverse forms: entertainment places, themed malls, revamping of historical settings, and so on. This pervading tendency led to changes in planning attitudes, seen as historical in face of their global claims. However, many of the innovative theoretical issues now linked to the concept of place have not been thoroughly examined in the Planning area so far. Additionally, the concept is now engrossing the research interests of other disciplines, which results in important contributions being introduced to its foundational aspects, hence, establishing a transdisciplinary condition to its essence. In fact, planning theory seems now ripe to ‘replace’ its prevalent understanding of place. This paper intends to suggest some of the directions to follow in such an attempt. Methodologically, it will pursue the directions set by three types of conflicts generated by the variations: controversies, contrasts, and challenges.
To approach the variations in terms of the controversies implies to realize the duality in the roles places can perform in today’s societal behaviours: a functional as well as an existential one. Indeed, for some scholars, the new invented places of today are appropriated as new places of urbanity, leading to think that we are on the brink of a situation where the perception of place can influence the perception of ‘urbanity’ – urbanity understood as that unique quality forwarded by cities to their citizens in terms of communication and sociability – ultimately entailing new ways of enjoying the urbanity cities have to offer. Contrasts associated to the variations bring to light a duality present in the Planning discipline itself. Previously, the discipline had that the sense of place would derive exclusively from society’s practices, emerging from them as a social construction, whereas today, besides being a social construction, place is also regarded as an economic construction. This is a condition that sometimes exacerbates inherent social contrasts, producing cities dotted with fragments of exception believed to act upon the urban structure as disintegrative factors evidencing latent differences. Finally, to approach the variations in terms of their challenges will direct the focus towards the planning decisions city’s administrators are faced to take when settling to embark on the placemaking + placemarketing game – or not – a challenge cities increasingly are compelled to adhere to, often at the risk of engaging on demanding competitive practices.
