EFEKTIVITAS LAYANAN KONSELING KELOMPOK DENGAN PENDEKATAN BEHAVIORAL MELALUI TEKNIK SHAPING UNTUK MENGURANGI PROKRASTINASI AKADEMIK SISWA KELAS VIII SMP NEGERI 2 BARAT KABUPATEN MAGETAN
Authors: Ernawati Elly , Sumarwoto Vitalis Djarot
Published: March 2018

Prokrastinasi akademik adalah suatu kecenderungan penundaan tugas yang dilakukan secara terus-menerus oleh seseorang dan lebih memilih melakukan aktivitas lain yang kurang bermanfaat bagi dirinya. Perilaku siswa tersebut pada hakikatnya dapat berdampak pada aspek sosial, psikologis, maupun akademik, yang berujung pada terhambatnya perkembangan maupun pencapaian tujuan pendidikan. Ditinjau dari aspek sosial sangat mungkin siswa tidak memperoleh simpati dari teman-teman atau dijauhkan dari interaksi pergaulan. Ditinjau dari aspek psikologis perilaku prokastinasi bisa mengganggu aktivitas belajar dan kinerja yang diperlukan dalam mencapai tujuan pembelajaran. Secara akademik perilaku prokastinasi dapat menghambat bidang akademik, khususnya dalam mewujudkan prestasi-prestasi belajar di sekolah.

       Bertolak dari uraian di atas maka perlu segera dicarikan solusinya agar tidak menghambat perkembangan dan pencapaian prestasi belajar siswa di sekolah. Salah satu solusi terhadap masalah di atas adalah dengan memberikan layanan konseling kelompok berbantuan dengan pendekatan behavioral melalui teknik shaping. Hakikat layanan konseling kelompok adalah layanan konseling yang memungkinkan konseli (siswa) memperoleh kesempatan untuk membahas dan mengentaskan masalah yang dihadapinya melalui dinamika kelompok.

       Inti pokok pendekatan behavioral adalah penggunaan metode ilmiah dalam bidang psikoterapi, dengan memodifikasi perilaku melalui rekayasa lingkungan sehingga terjadi proses belajar untuk perubahan tingkah laku. Teknik shaping merupakan prosedur yang digunakan untuk membentuk perilaku individu (siswa) yang diinginkan dengan memberikan reinforcement pada setiap tingkah laku yang ditampilkan. Melalui terapi layanan konsdeling kelompok dengan pendekatan behavioral melalui teknik shaping hakikatnya adalah bahwa bantuan pemecahan masalah yang dilakukan secara kelompok dari seorang konselor yang ditujukan kepada individu (siswa) dengan harapan akan terjadi perubahan tingkah laku. Selanjutnya siswa yang telah berubah perilakunya setelah diberi terapi kemudian diberi reinforcement. Perilaku yang diupayakan dan diharapkan mengalami perubahan adalah  berkurangnya kecenderungan menunda tugas yang dibebankan kepada konseli (siswa), yang dilakukan secara terus-menerus.

El presente ensayo postula, como eje detonador de toda la disertación reflexiva, establecer vínculos y bifurcaciones entre el arte y el diseño. Comenzaremos por tratar de establecer una definición de lo que se entiende por arte, luego una definición de diseño gráfico y por último un apartado sobre cómo se conectan estas dos disciplinas del saber humano, hasta dónde se auxilian y los espacios que las delimitan y las hacen  “lo mismo y lo otro”, sin ánimos de mostrarlas antagónicas o como usurpadoras de sus linderos, lejos de esta idea aseguramos que se comunican y se hermanan para luego desarticularse y recuperar de este modo su hegemonía, dando la oportunidad de reflexiones como las que continuación se presentan.

A Comparative Study of the Mathematics Textbooks of Korea and the United States based on a Learning Trajectory for the Concept of Slope
Authors:   The Korea Society Of Educational Studies In Mathematics, Park JongHee , Lee Soo Jin
Published: March 2018

The understanding of the concept of slope in terms of the rate of change serves as the foundation for developing meaningful calculus concepts. The purpose of our study was two-fold: Firstly, we attempted to develop a learning trajectory for the slope of a linear function using the rate of change; secondly, we used the trajectory to compare Korean mathematics textbooks with those of the U.S. standard-based curriculum CMP. After developing a learning trajectory of slope for the linear function via an in-depth analysis of the past literature, we compared and contrasted the textbooks of the two countries. Specifically, we analyzed how the textbooks of the two countries defined and described the terminologies, how they introduced the slope concept including the way how slope was represented (e.g., double number line and strip diagram), and finally the affordance of the two different perspectives of proportional relationships. Our results suggest that a careful consideration of the method to introduce the slope concept, the consistency of the terminology usage and explanations, and the devising of instructional materials that enhance the student awareness of the invariant relationship between two quantities using proportional reasoning are imperative for students’ meaningful development of more advanced mathematics.
An Analysis of Second-Grade Students’ Mathematical Activities Using Broken Rulers
Authors:   The Korea Society Of Educational Studies In Mathematics, Lim Miin , Chang Hyewon
Published: March 2018

This study focuses on investigating the strategies that are used to measure length by using two broken rulers by second grade students that can measure length using a normal ruler. As per the results of the study, when students measure length using broken rulers, the strategies they use are counting units, thinking of the starting point as 0 and reading the number corresponding to the hash mark, and using subtraction to get the number of units of length. Also, some errors were observed in the study. Some students thought of the starting point as 1 and read the number corresponding to the hash mark. Another students unconditionally read the number of the end point. Based on the results of the analysis, some significant implications for the teaching and learning of the measurement domain were derived.
Português como L2: o ensino da disciplina no curso de Letras Libras da UFGD
Authors: Oliveira Ednei Nunes de
Published: March 2018

Este trabalho é um relato da experiência vivenciada no ensino da disciplina “A Língua Portuguesa como Segunda Língua para Surdos”, ministrada no ano de 2017, no curso de Licenciatura em Letras – Língua Portuguesa/Língua Brasileira de Sinais, com uma turma de alunos surdos e ouvintes. Foi possível perceber que, ainda que a disciplina tenha sido ministrada para estudantes universitários, a Língua Portuguesa para surdos ainda deve ser trabalhada nesse nível de ensino, tendo-se a preocupação de letramento. Nesse sentido, foi possível notar que o ensino do Português para surdos, no curso, não deve se limitar a atividades de reflexão sobre abordagens e fundamentos teóricos e metodológicos de ensino de segunda língua para surdos, mas principalmente com normas e regras gramaticas, priorizando atividades de leitura, produção e interpretação de textos.

Authors: Francklin Adelino
Published: March 2018

Este artigo visa analisar a discrepância entre os discursos salvacionistas em favor do uso das tecnologias na Educação e o trabalho docente na Rede Pública Estadual de Minas Gerais (REE/MG). Justifica-se pelo aumento do número de discursos da Secretaria Estadual de Educação de Minas Gerais (SEE/MG), em entre os anos de 2003 a 2014, em favor do uso das tecnologias na Educação como necessidade para elevar a qualidade no ensino. Destarte, a SEE/MG adquiriu computadores, lousas digitais para as escolas da REE/MG e tablets educacionais para os professores que atuavam na mesma rede de ensino. Foram aplicados questionários e realizadas entrevistas semiestruturadas com cinco professores secundários de diferentes disciplinas que atuavam na REE/MG. A abordagem da pesquisa foi qualitativa. As análises apontam que houve ausência de formação continuada para o uso das tecnologias pelos professores da REE/MG; obstáculos para o uso das tecnologias na educação na REE/MG e que a SEE/MG adotou uma visão instrumentalista sobre as tecnologias na educação no contexto estudado.
Unravelling intrusion-induced forced fold kinematics and ground deformation using 3D seismic reflection data
Authors: Reeves Jennifer , Magee Craig , Jackson Christopher Aiden-Lee
Published: March 2018

Sills emplaced at shallow-levels are commonly accommodated by overburden uplift, producing forced folds. We examine ancient forced folds developed above saucer-shaped sills using 3D seismic reflection data from the Canterbury Basin, offshore SE New Zealand. Seismic-stratigraphic relationships indicate sill emplacement occurred incrementally over ~31 Myr between the Oligocene (~35–32 Ma) and Early Pliocene (~5–4 Ma). Two folds display flat-topped geometries and amplitudes that decrease upwards, conforming to expected models of forced fold growth. Conversely, two folds display amplitudes that locally increase upwards, coincident with a transition from flat-topped to dome-shaped morphologies and an across-fold thickening of strata. We suggest these discrepancies between observed and expected forced fold geometry reflect uplift and subsidence cycles driven by sill inflation and deflation. Unravelling these forced fold kinematic histories shows complex intrusion geometries can produce relatively simple ground deformation patterns, with magma transgression corresponds to localisation of uplift.
Shape Memory-Enhanced Electrical Self-Healing of Stretchable Electrodes

Published: March 2018

A novel shape memory-based self-healable stretchable electrode was explored by embedding the silver nanowires (AgNWs) network into a healable polymer matrix. Unlike the traditional shape memory-assisted self-healing, pre-stretching to the temporary shapes, which was fixed in a typical shape, memory thermo-mechanical programming significantly enhanced the thermo-triggered healing performance. The morphological as well as conduction variations during the healing process were investigated. The enhancing effect of the pre-stretching on the healing efficiency was emphasized, which was expected to attribute to the release of the pre-stored strain energy driving the closure of the scratch. The findings disclosed how to utilize the shape memory effect to improve the biomimetic properties for the stretchable electrodes, which may greatly benefit the application of the intelligent polymers in the field of multi-functional flexible electronics.
The Effect of Climate Conditions on the Relation between Energy Efficiency and Urban Form
Authors: Tsirigoti Dimitra , Tsikaloudaki Katerina
Published: March 2018

Urban sustainability has been connected to form and compactness of the urban tissue. At the same time the relationship between urban form and energy efficiency is strongly affected by climate. This paper investigates the effect of climate conditions on the relation between urban morphology and energy efficiency of urban blocks, focusing on the Greek city context. A set of building block typologies is analyzed with regard to their form factors such as S/V ratio, coverage ratio and building ratio for the climatic conditions of two cities, each one belonging to a different climatic zone. Heating and cooling loads are calculated at an urban block scale for the climate of the city of Thessaloniki (zone C) and of the city of Heraklion (zone A) in order to draw conclusions about the relation between geometry factors and energy efficiency. The results of the research indicate that there is a strong relationship between urban morphology factors and energy efficiency and that the total load demand of urban blocks can be described as a function of form parameters. Results of the research, concerning the energy demand calculation, are valuable since they indicate the energy profile of each typology according to climate and can be used for defining different urban strategies towards sustainability in a context-based climate dependent analysis.
Multiarea Voltage Controller for Active Distribution Networks
Authors: Cagnano Alessia , De Tuglie Enrico , Bronzini Marco
Published: March 2018

The aim of this paper was to develop a multi-area decentralized controller for improving the voltage profile of large active distribution networks. Voltages at control buses of each area are kept as close as possible to their reference values by managing the reactive power of distributed generators within the same areas. Moreover, in order to avoid exchanging a considerable amount of data on more or less large portions of the network, the proposed methodology adopted an equivalent reduced network for each area. This equivalent network model is seen at control buses and nodes where distributed generation units are connected. With this simplification, each area controller will have to evaluate simultaneously, the unknown parameters of the reduced network and the optimal control laws for the voltage profile optimization of its control area. To comply with this exigency, a multi-objective optimization problem was formulated. The solution of this problem formulation was found by adopting an algorithm operating in the continuous time domain. Test results are provided on a 49-bus distribution network, demonstrating the effectiveness of the developed methodology.
Assessing the Association of Food Preferences and Self-Reported Psychological Well-Being among Middle-Aged and Older Adults in Contemporary China-Results from the China Health and Nutrition Survey
Authors: Lee Yen-Han , Shelley Mack , Liu Ching-Ti , Chang Yen-Chang
Published: March 2018

China has undergone rapid social transitions within the last few decades. However, mental health issues, challenges to psychological well-being, and poor dietary choices have gradually surfaced. These health concerns are related to the rapid growth of the aging population and of the fast-paced industrialized society. Nevertheless, there is little knowledge about food preferences and psychological well-being measurements in contemporary China. Applying the 2011 China Health and Nutrition Survey (CHNS) with a cross-sectional study design (n = 7970), we conducted multinomial logistic regression models to investigate the associations of food preferences, including fast food, salty snacks, fruits, vegetables, and sweetened beverages, with psychological well-being among Chinese middle-aged and older adults (age ≥ 45). Food preferences are mostly associated with psychological well-being (p < 0.05). However, respondents’ preferences regarding fast food, salty snacks, and sweetened beverages are associated not only with poorer psychological health status, but also with positive psychological well-being. We speculate that Chinese older adults may consume Westernized fast food and salty snacks as pleasure to the palate due to the recent Westernization in modern China. We also provide practical implications of results from this preliminary study.
Caloric Restriction and Its Effect on Blood Pressure, Heart Rate Variability and Arterial Stiffness and Dilatation: A Review of the Evidence
Authors: Nicoll Rachel , Henein Michael
Published: March 2018

Essential hypertension, fast heart rate, low heart rate variability, sympathetic nervous system dominance over parasympathetic, arterial stiffness, endothelial dysfunction and poor flow-mediated arterial dilatation are all associated with cardiovascular mortality and morbidity. This review of randomised controlled trials and other studies demonstrates that caloric restriction (CR) is capable of significantly improving all these parameters, normalising blood pressure (BP) and allowing patients to discontinue antihypertensive medication, while never becoming hypotensive. CR appears to be effective regardless of age, gender, ethnicity, weight, body mass index (BMI) or a diagnosis of metabolic syndrome or type 2 diabetes, but the greatest benefit is usually observed in the sickest subjects and BP may continue to improve during the refeeding period. Exercise enhances the effects of CR only in hypertensive subjects. There is as yet no consensus on the mechanism of effect of CR and it may be multifactorial. Several studies have suggested that improvement in BP is related to improvement in insulin sensitivity, as well as increased nitric oxide production through improved endothelial function. In addition, CR is known to induce SIRT1, a nutrient sensor, which is linked to a number of beneficial effects in the body.
Diazoxide Improves Mitochondrial Connexin 43 Expression in a Mouse Model of Doxorubicin-Induced Cardiotoxicity
Authors: Pecoraro Michela , Ciccarelli Michele , Fiordelisi Antonella , Iaccarino Guido , Pinto Aldo , Popolo Ada
Published: March 2018

Doxorubicin (DOXO) administration induces alterations in Connexin 43 (Cx43) expression and localization, thus, inducing alterations in chemical and electrical signal transmission between cardiomyocytes and in intracellular calcium homeostasis even evident after a single administration. This study was designed to evaluate if Diazoxide (DZX), a specific opener of mitochondrial KATP channels widely used for its cardioprotective effects, can fight DOXO-induced cardiotoxicity in a short-time mouse model. DZX (20 mg/kg i.p.) was administered 30 min before DOXO (10 mg/kg i.p.) in C57BL/6j female mice for 1–3 or seven days once every other day. A recovery of cardiac parameters, evaluated by Echocardiography, were observed in DZX+DOXO co-treated mice. Western blot analysis performed on heart lysates showed an increase in sarco/endoplasmic reticulum Ca2+-ATPase (SERCAII) and a reduction in phospholamban (PLB) amounts in DZX+DOXO co-treated mice. A contemporary recovery of intracellular Ca2+-signal, detected spectrofluorometrically by means of FURA-2AM, was observed in these mice. Cx43 expression and localization, analyzed by Western blot and confirmed by immunofluorescence analysis, showed that DZX co-treatement increases Cx43 amount both on sarcoplasmic membrane and on mitochondria. In conclusion, our data demonstrate that, in a short-time mouse model of DOXO-induced cardiotoxicity, DZX exerts its cardioprotective effects also by enhancing the amount Cx43.

Published: March 2018

Kidney stones are one of the oldest known and common diseases in the urinary tract system. Various human studies have suggested that diets with a higher intake of vegetables and fruits play a role in the prevention of kidney stones. In this review, we have provided an overview of these dietary plants, their main chemical constituents, and their possible mechanisms of action. Camellia sinensis (green tea), Rubus idaeus (raspberry), Rubia cordifolia (common madder), Petroselinum crispum (parsley), Punica granatum (pomegranate), Pistacia lentiscus (mastic), Solanum xanthocarpum (yellow-fruit nightshade), Urtica dioica (stinging nettle), Dolichos biflorus (horse gram), Ammi visnaga (khella), Nigella sativa (black-cumin), Hibiscus sabdariffa (roselle), and Origanum vulgare (oregano) have received considerable interest based on scientific evidence. Beside these dietary plants, phytochemicals—such as catechin, epicatechin, epigallocatechin-3-gallate, diosmin, rutin, quercetin, hyperoside, and curcumin—as antioxidant dietary phyto-phenols were found to be effective for the prevention of urolithiasis (the process of stone formation in the urinary tract). The main underlying mechanisms of these dietary plants and their isolated phytonutrients in the management of urolithiasis include diuretic, antispasmodic, and antioxidant activity, as well as an inhibitory effect on crystallization, nucleation, and aggregation of crystals. The results as presented in this review demonstrate the promising role of dietary plants and phytophenols in the prevention and management of kidney stones. Further investigations are required to confirm the safety and efficacy of these compounds.

A series of B-ring, halo-substituted chalcones and azachalcones were synthesized to evaluate and compare their anti-inflammatory activity. Mouse BALB/c macrophage RAW 264.7 were pre-treated with 10 μg/mL of each compound for one hour before induction of inflammation by lipopolysaccharide (1 μg/mL) for 6 h. Some halo-chalcones and -azachalcones suppressed expression of pro-inflammatory factors toll-like receptor 4 (TLR4), IκB-α, transcription factor p65, interleukine 1β (IL-1β), IL-6, tumor necrosis factor α (TNF-α), and cyclooxygenase 2 (COX-2). The present results showed that the synthetic halo-azachalcones exhibited more significant inhibition than halo-chalcones. Therefore, the nitrogen atom in this series of azachalcones must play a more crucial role than the corresponding C-2 hydroxyl group of chalcones in biological activity. Our findings will lay the background for the future development of anti-inflammatory nutraceuticals.
Opening the Heart of Science: A Review of the Changing Roles of Research Libraries
Authors: Revez Jorge
Published: March 2018

In a world of information overload and data deluge, is opening science a research library’s duty? Or is the openness of science deeply changing libraries, ultimately converting them into something else? The purpose of the review is to highlight the challenging issues stemming from the relationship between research and libraries. A broad literature analysis was performed focused on the intersection of three different perspectives: (1) the future of research libraries, (2) the emerging new roles, and (3) the ongoing openness of science. Libraries are still at the heart of science but challenged by several stakeholders within the complexity of present science production and communication. Research support services, research data management, or research information management are emerging roles, among others, sustaining an open path where libraries thrive to be more collaborative while looking forward to establishing new partnerships.
Data Summarization in the Node by Parameters (DSNP): Local Data Fusion in an IoT Environment
Authors: Maschi Luis , Pinto Alex , Meneguette Rodolfo , Baldassin Alexandro
Published: March 2018

With the advent of the Internet of Things, billions of objects or devices are inserted into the global computer network, generating and processing data at a volume never imagined before. This paper proposes a way to collect and process local data through a data fusion technology called summarization. The main feature of the proposal is the local data fusion, through parameters provided by the application, ensuring the quality of data collected by the sensor node. In the evaluation, the sensor node was compared when performing the data summary with another that performed a continuous recording of the collected data. Two sets of nodes were created, one with a sensor node that analyzed the luminosity of the room, which in this case obtained a reduction of 97% in the volume of data generated, and another set that analyzed the temperature of the room, obtaining a reduction of 80% in the data volume. Through these tests, it has been proven that the local data fusion at the node can be used to reduce the volume of data generated, consequently decreasing the volume of messages generated by IoT environments.
Lightweight Active Object Retrieval with Weak Classifiers
Authors: Czúni László , Rashad Metwally
Published: March 2018

In the last few years, there has been a steadily growing interest in autonomous vehicles and robotic systems. While many of these agents are expected to have limited resources, these systems should be able to dynamically interact with other objects in their environment. We present an approach where lightweight sensory and processing techniques, requiring very limited memory and processing power, can be successfully applied to the task of object retrieval using sensors of different modalities. We use the Hough framework to fuse optical and orientation information of the different views of the objects. In the presented spatio-temporal perception technique, we apply active vision, where, based on the analysis of initial measurements, the direction of the next view is determined to increase the hit-rate of retrieval. The performance of the proposed methods is shown on three datasets loaded with heavy noise.
A Robust Adaptive Unscented Kalman Filter for Nonlinear Estimation with Uncertain Noise Covariance
Authors: Zheng Binqi , Fu Pengcheng , Li Baoqing , Yuan Xiaobing
Published: March 2018

The Unscented Kalman filter (UKF) may suffer from performance degradation and even divergence while mismatch between the noise distribution assumed as a priori by users and the actual ones in a real nonlinear system. To resolve this problem, this paper proposes a robust adaptive UKF (RAUKF) to improve the accuracy and robustness of state estimation with uncertain noise covariance. More specifically, at each timestep, a standard UKF will be implemented first to obtain the state estimations using the new acquired measurement data. Then an online fault-detection mechanism is adopted to judge if it is necessary to update current noise covariance. If necessary, innovation-based method and residual-based method are used to calculate the estimations of current noise covariance of process and measurement, respectively. By utilizing a weighting factor, the filter will combine the last noise covariance matrices with the estimations as the new noise covariance matrices. Finally, the state estimations will be corrected according to the new noise covariance matrices and previous state estimations. Compared with the standard UKF and other adaptive UKF algorithms, RAUKF converges faster to the actual noise covariance and thus achieves a better performance in terms of robustness, accuracy, and computation for nonlinear estimation with uncertain noise covariance, which is demonstrated by the simulation results.
RSE, GRH et Supply Chain . La stratégie de réponse d’Apple à la demande sociale d’amélioration des conditions de travail chez les sous-traitants
Authors: Nicolas Eline
Published: March 2018

Le « problème social » des conditions de travail chez les sous-traitants impose aux donneurs d’ordre la mise en place d’un management intégrant l’analyse des sources de risques (Supply Chain Disruption Management). Cette demande sociale implique au sein de la dyade ST-DO des modalités de contrôle de l’expression des responsabilités de chacun et une communication/un dialogue avec les parties prenantes. La stratégie de réponse à cette demande sociale doit alors permettre d’apporter des solutions aux attentes de réduction de l’incertitude et d’accès à l’information des parties prenantes. La problématique porte ici sur la compréhension de la formulation d’une réponse à une demande sociale d’amélioration des conditions de travail chez les sous-traitants au travers du cas Apple. L’étude présente une analyse des « Rapports de progrès de la responsabilité des fournisseurs » du géant de l’informatique Apple de leur naissance en 2007 à aujourd’hui. Le traitement de ce corpus à l’aide du logiciel d’analyse textuelle Alceste a permis de mettre en lumière une stratégie de réponse structurée autour de l’organisation des relations partenariales de la dyade DO-ST, de la gestion des risques chez le ST et de la structuration de la relation d’emploi chez le ST.
Entre la dichotomie et le pluralisme : la complexité des idées libérales de Domingo F. Sarmiento. Étude préliminaire de sa conférence prononcée devant la Société Historique de Rhode Island en 1865
Authors: Donatello Luis , Levita Gabriel , Moallic Benjamin
Published: March 2018

Cette étude cherche à complexifier les interprétations de la pensée sarmentienne et le caractère libéral de ses idées en partant d’une analyse d’une conférence que Sarmiento a prononcé devant la Société Historique de Rhode Island en 1865. Nous y montrons combien il est difficile de le réduire à sa caricature de simple ennemi des indiens et des gauchos, de même que nous montrons que la dichotomie civilisation-barbarie n’est chez lui ni univoque ni invariante tout au long de son œuvre. Dans son allocution il récupère quelques éléments de la culture espagnole et se lance à la recherche d’une particularité latino-américaine, tout en soulignant l’importance du fédéralisme politique. De plus il met en exergue le rôle crucial de la religion afin de souligner la matrice religieuse des cultures civiques, celle du pluralisme religieux nordaméricain, en tout opposé au modèle monopolistique du catholicisme colonial.
Guerre des chefs et troisième tour électoral en Équateur
Authors: Labarthe Sunniva , Saint-Upéry Marc

Le conflit aigu qui oppose l’ancien président équatorien Rafael Correa et son dauphin Lenín Moreno depuis juillet 2017 a d’abord éclaté sur les réseaux sociaux avant de s’étendre à l’ensemble de l’appareil d’État et de diviser profondément leur mouvement politique, Alianza País. Initialement conçue comme une « transition contrôlée » de style Poutine-Medvedev, la passation de pouvoir entre Correa et Moreno s’est rapidement transformée en « trahison » de type Uribe-Santos. L’arrestation du vice-président Jorge Glas, collaborateur dévoué et ami intime de l’ancien président, est une étape cruciale d’un combat pour l’hégémonie politique qui voit Lenín Moreno s’efforcer de tirer profit de la lutte contre la corruption et les abus autoritaires de la décade corréiste. Au-delà des querelles de personne et du marchandage des loyautés, la crise d’Alianza País met à jour les limites et les contradictions d’une « Révolution citoyenne » qui était déjà en nette perte de vitesse et de crédibilité depuis au moins 2015.
Lima, la révolution de la sociabilité
Authors: Martuccelli Danilo
Published: March 2018

L’article propose une interprétation de la transformation survenue dans la ville de Lima autour de la formation d’une nouvelle sociabilité urbaine. L’argument est présenté en deux grandes étapes. Dans un premier moment, l’article précise comment cette sociabilité commune, tout en participant à l’expansion d’un processus d’horizontalisation sociale et culturelle, ne peut pas être associée cependant ni avec un contre-projet hégémonique ni avec un acteur populaire homogène. Il s’agit plutôt d’une sociabilité produite par une myriade d’acteurs, sans unité, qui a néanmoins fini par engendrer un régime d’interaction particulier. Dans un second moment, il s’attarde sur l’analyse de trois grandes manifestations de cette sociabilité : l’idéal de la fusion, le phénomène chicha et la figure de l’ achorado .

Dans la création de son propre personnage grâce à son génie de la propagande et de la mise en scène, il devient une figure tutélaire, et accomplit une de ses œuvres majeures. Dans la mise au point d’un système de contrôle de la société cubaine et d’un système carcéral unique dans leur genre qui expliquent en grande partie la longévité du régime.
Danser avec les États
Authors: Sur Serge
Published: March 2018

Depuis les années 1990, l’Europe a connu un processus de fragmentation, et ses États les plus anciens subissent aujourd’hui des tentations sécessionnistes. Ailleurs, nombre d’intégrités territoriales ont volé en éclat et la mondialisation accouche, de fait, d’une multiplication des structures étatiques. Sur l’impuissance de nombre des nouveaux États rôde l’ombre des empires, mal disparus ou renaissants, et la sécession ne garantit pas le fonctionnement harmonieux des nouveaux États.
Les États au Moyen-Orient : crise et retour
Authors: Schmid Dorothée
Published: March 2018

Les révolutions arabes ont frappé des États dysfonctionnels qui se maintenaient basés sur l’usage récurrent de la violence. Mais elles ont aussi produit des réformes dans ceux qui ont tenu, et la redécouverte des vertus des États efficaces dans les pays ayant entrepris une transition démocratique, sans parler des revendications d’États des minorités. Les Occidentaux sont mal préparés à cette revitalisation d’une demande d’État qui passera par l’émergence des sociétés civiles et comporte encore bien des inconnues.
