Le chartisme
Authors: Chase Malcolm
Published: November 2020

De 1838 à 1858, en Grande-Bretagne, dans la première société industrielle, le chartisme fut un mouvement ouvrier inédit, mobilisant, à son apogée, trois millions d’hommes et de femmes. Les militants de la Charte du Peuple luttaient pour le suffrage universel et une société démocratique qui permettent à chacun de vivre dignement de son travail. À travers des pétitions de masse adressées au Parlement, des rassemblements et des manifestations, des journaux, des chants et des communautés villageoises, les chartistes envisageaient une autre société. Le chartisme étudie le mouvement dans son intégralité, en Grande-Bretagne et en Irlande. S’appuyant sur une grande maîtrise des archives et des publications d’époque, l’auteur s’est particulièrement intéressé à l’expérience des hommes, des femmes et des enfants du mouvement. Le récit haletant est entrecoupé de courtes « vies chartistes », qui constituent autant de passionnantes biographies. Cet ouvrage est, depuis 1913, le premier en français sur le sujet.
La genèse de l’expédition franco-britannique de 1956 en Égypte
Authors: Bernard Jean-Yves
Published: November 2020

Au confluent de la guerre froide, de la décolonisation et du conflit israélo-arabe, la crise de Suez de 1956 tient une place particulière dans l’histoire des relations internationales depuis 1945. À ses acteurs principaux, Grande- Bretagne et France, associés dans une intervention militaire contre l’Égypte, l’historiographie a invariablement assigné des mobiles de politique étrangère ou coloniale : les Anglais voulaient préserver leurs positions dans le monde arabe et protéger leurs intérêts pétroliers ; les Français désiraient renverser Nasser, soutien essentiel des rebelles algériens.

S’agit-il donc, dans le cadre classique d’un affrontement entre nationalisme égyptien et impérialismes anglais et français, d’un retour étonnant et anachronique à la politique de la canonnière ? L’auteur démontre que les choix des deux gouvernements trouvent en réalité leurs raisons dans la politique intérieure au sens large, ressac conservateur de l’après-guerre en Grande-Bretagne et crise de la IVe République en France. Son étude porte à la fois sur les développements internes dans les deux pays à partir de 1955 et sur leurs politiques égyptiennes, sans négliger les plans militaires et les considérations coloniales. Outre les abondantes sources secondaires, Jean-Yves Bernard utilise l’ensemble des archives publiques françaises et anglaises disponibles, les fonds des partis politiques, les archives personnelles et les témoignages oraux de plusieurs acteurs et contemporains des faits.
Julius et Ethel Rosenberg. Un déni de justice
Authors: Pinto Roger
Published: November 2020

Dans les années 1950, le procès d’un jeune couple de juifs américains, communistes de surcroît, accusés d’avoir transmis aux Soviétiques le secret de la bombe atomique, a passionné l’opinion dans leur pays et dans le monde entier. Julius et Ethel Rosenberg proclameront leur innocence jusqu’à la chaise électrique. Le climat politique de l’époque ne leur permettait pas d’être entendu.

Le procès devant l’opinion publique commence alors. Il se poursuit encore aujourd’hui. Les uns sont mus par le parti pris ou le remords d’avoir été staliniens ; les autres par un devoir d’humanité et la passion des droits de l’homme. Mais tous ceux qui ont vécu cette époque éprouvent gêne et affliction à l’évocation de la tragédie de ce couple et de ses deux fils.

Un premier ouvrage du même auteur intitule La tragédie de Julius et Ethel Rosenberg - Le déni de justice est paru en 1986. À partir des archives soviétiques et américaines couvrant la période 1986-1997, aujourd’hui accessibles, le juriste confirme qu’en tenant compte des faits actuellement avérés, le procès et les condamnations doivent être cassés pour déni de justice.
Être historien des relations internationales
Authors: Girault René
Published: November 2020

Pour René Girault, « être historien des relations internationales », ce n’est pas seulement faire de l’histoire des relations inter- nationales ou développer des recherches dans ce domaine, c’est aussi se poser des questions d’historien ; c’est réfléchir sans cesse sur la validité de ce qui constitue sa propre discipline. Parce que cette préoccupation marque constamment et fructueusement son œuvre, René Girault s’inscrit dans la prestigieuse lignée de Pierre Renouvin et de Jean-Baptiste Duroselle.

Ses nombreux disciples ont voulu lui rendre hommage en rassemblant certains de ses textes et en sélectionnant précisément ceux qui rendent le mieux compte de sa réflexion historique. A n’en point douter, il existe une « méthode Girault », une méthode qui, prolongeant et renouvelant celle de Pierre Renouvin, tend à écrire une histoire globale des relations internationales, avec un horizon bien plus large que celui de l’histoire diplomatique traditionnelle. En analysant scrupuleusement les liens entre l’économique et le poli- tique, en mesurant le poids des représentations et des imaginaires sociaux, en démontant les mécanismes de décision, René Girault donne des éclairages très originaux sur des questions fondamentales : 1’« impérialisme », la « puissance », la place de la France dans le monde, la construction de l’Europe et l’identité européenne. Grand historien, René Girault est aussi un intellectuel en son siècle, pour qui toute réflexion sur l’histoire est aussi une réflexion sur la démocratie.
Émigration alsacienne aux États-Unis 1815-1870
Authors: Fouché Nicole
Published: November 2020

Cet ouvrage, fruit d’un doctorat soutenu, en 1987, à Paris-I, est une étude quantitative et qualitative de l’émigration alsacienne aux États-Unis de 1815 à 1870. Il dresse une sociologie et une géographie du phénomène. Il s’intéresse à toutes les étapes de l’émigration : départ, traversée, installation. Malgré toutes les difficultés qui caractérisèrent à l’époque, l’émigration aux Etats-Unis, les Alsaciens, tout au long du XIXe siècle, restèrent fidèles à cette destination. Ils avaient de bonnes raisons de quitter l’Alsace, mais, surtout, ils prenaient pied dans un pays où les chances de développement économique ainsi que de progrès social étaient très ouvertes et très réelles.

L’épisode de la colonisation du Texas par Henri Castro ne représente que 4% de l’émigration alsacienne aux États-Unis : l’importance de cet intermède mouvementé et haut en couleur se mesure plus à sa dimension symbolique qu’à sa réalité objectivement quantifiable.
Quand la dissidence devient jugement : retour sur les opinions séparées en droit international pénal
Authors: Ramseier Alexandra , Scalia Damien
Published: November 2020

Les opinions séparées sont une pratique courante au sein des cours suprêmes de nombreux États de common law comme devant les juridictions internationales de protection des droits humains ou au sein de la Cour internationale de justice. Elles permettent de comprendre une décision ou d’entrevoir le développement à venir du droit. Importées en droit international pénal, leur raison d’être et leur légitimité sont plus douteuses : entre narcissisme de certain·e·s juges, violation du secret des délibérés et remise en cause de l’autorité (morale) de la chose jugée, le bien-fondé de cette pratique est ici questionné.

Objective:

To evaluate the potential therapeutic effect of Sang-Yod rice bran hydrolysates (SRH) and in combination with lisinopril against hypertension, endothelial dysfunction, vascular remodeling, and oxidative stress in rats with nitric oxide deficiency-induced hypertension.

Methods:

Hypertension was induced in male Sprague-Dawley rats by administration of a nitric oxide synthase inhibitor, Nω- nitro-L-arginine methyl ester (L-NAME) in drinking water for 6 weeks. Hypertensive rats were administered daily with SRH (500 mg/kg/day), lisinopril (1 mg/kg/day), or the combination of SRH and lisinopril by gastric lavage for the last 3 weeks of L-NAME treatment. Hemodynamic status, vascular reactivity to vasoactive agents, and vascular remodeling were assessed. Blood and aortic tissues were collected for measurements of oxidative stress markers, plasma angiotensin-converting enzyme (ACE) activity, plasma angiotensin II, and protein expression.

Results:

L-NAME induced remarkable hypertension and severe oxidative stress, and altered contents of smooth muscle cells, elastin, and collagen of the aortic wall. SRH or lisinopril alone reduced blood pressure, restored endothelial function, decreased plasma ACEs and angiotensin II levels, alleviated oxidant markers and glutathione redox status, and restored the vascular structure. The effects were associated with increased expression of endothelial nitric oxide synthase and decreased expression of gp91phox and AT1R expression. The combination of SRH and lisinopril was more effective than monotherapy.

Conclusions:

SRH alone or in combination with lisinopril exert an antihypertensive effect and improve endothelial function and vascular remodeling through reducing oxidative stress and suppressing elevated renin-angiotensin system.

Published: November 2020

The corrosion of reinforcement steel bars in concrete has been established as the major factor causing
widespread degradation of concrete structures. Corrosion of reinforcement in concrete leads to reduction of
good bonding between steel and concrete, decrease of steel cross-sectional area, cracking and loss of
serviceability. This paper investigates the behavior and Performance of reinforcement bar embedded in
concrete structure under a variety of aggressive environments. The study used 16 mm diameter
reinforcement bars embedded in concrete with a uniform cover of 50 mm in 200 mm x 200 mm x 750 mm
concrete beam, the curing period of concrete is 28 days. After completion of 28 days’ moisture curing period,
the beam was loaded in flexure causing cracking of the concrete, thereby exposing the steel reinforcements.
The cracked reinforced concrete beams were then immersed in different aggressive solutions of H2So4
(Sulfuric Acid), HCl (hydrochloric acid), HNO3 (hydrogen trioxonitrate), NaOH (sodium hydroxide) and NaCl
(Sodium Chloride) for a duration of six months. At the end of this curing period, the embedded steel
reinforcement was removed and cleaned off the attached concrete, and then tested for change in strength,
diameter, and weight loss. The results obtained shows that corrosion affect steel reinforcement in concrete
under HCl, H2SO4 and HNO3 with 15%,13% and 11% very high rate change in strength respectively. Also, the
NaCl and HCl, were recorded with 15% and 11% very high rate effects on reduction/addition in diameter of
steel reinforcement respectively. And finally, the HCl, and H2SO4 were recorded with 24.1% having the same
and very high rate effects on reduction in weight (weight loss).

Intelligent Hybrid-Fuzzy Controller using VLLMS
Based Shunt Active Filter
Authors: Shaik Nagul Sharif and Sri Latha Veerla
Published: November 2020

The power quality problem in the power system is increased with the use of non-linear devices. Due to the
use of non-linear devices like power electronic converters, there is an increase in harmonic content in the
source current. Due to this there is an increase in the losses, instability and poor voltage waveform. To
mitigate the harmonics and provide the reactive power compensation, we use filters. There are different
filters used in the power system. Passive filters provide limited compensation, so active filters can be used for
variable compensation. In this work, a shunt active filter has been made adaptive using a Variable Leaky
Least Mean Square (VLLMS) based controller. Proposed adaptive controller can be able to compensate for
harmonic currents, power factor and nonlinear load unbalance. DC capacitor voltage has been regulated at a
desired level using a PI controller and a self-charging circuit technique. But, this scheme as two
disadvantages such as, tuning issues of current controller pre-requisites the traditional PI controller, which is
controlled by intelligent based Hybrid-Fuzzy-Logic controller for achieving good performance features. The
design concept of proposed intelligent Hybrid-Fuzzy controller for shunt active filter has been verified through
simulation analysis and results are presented with proper comparisons.
PV/Battery Hybrid System with Three Port
Converter fed Induction Motor Drive for Electric
Vehicle Application
Authors: V Pratyusha and Ch Chinna Veeraiah
Published: November 2020

In this paper, a classic proportional–integral (PI) control strategy as an energy management strategy (EMS)
and a microgrid stand-alone power system configuration are proposed to work independently out of
grid. The proposed system combines photovoltaics (PVs), and Battery. The system supplies a dump load
with its demand power. The system includes DC/DC and DC/AC converters, as well as a maximum power
point tracking (MPPT) to maximize the harvested energy from PV array. The classic PI control strategy is used
to control the main system parameters like state-of-charge (SOC) for the battery. The corresponding energy
management and control strategy are proposed to realize the power balance among three ports in different
operating scenarios, which comprehensively takes both the maximum power point tracking (MPPT) benefit
and the battery charging/discharging management into consideration. The simulations are conducted using
the Matlab/Simulink software to verify the operation performance of the proposed PV/battery hybrid
distributed power generation system with the corresponding control algorithms, where the MPPT control loop,
the battery charging/discharging management loop are enabled accordingly in different operating scenarios.

Published: November 2020

The new type of Coronavirus (SARS-CoV-2) is a highly contagious pathogen that causes severe acute respiratory syndrome and can be transmitted from human to human. COVID-19, which has been declared as a pandemic by the world health organization and is infected with more than 50 million people, is also responsible for the death of more than 1 million people. There is no sufficient data from randomized clinical trials that any potential treatment improves outcomes in COVID-19 patients. Chloroquine and hydroxychloroquine, antivirals such as favipiravir, lopinavir/ritonavir, immunomodulatory agents tocilizumab, siltuximab, and sarilumab, and anti-inflammatory drugs such as steroids are used for the treatment of COVID-19. Repurposing drugs can provide new treatment options faster than discovering new drugs due to the known safety profiles of existing drugs. On the other hand, there are new drug and vaccine trials for COVID-19. Many researchers, governmental or non-governmental institutions having clinical trials for COVID-19 drugs and vaccines. In this comprehensive review, we investigate the clinical features, management, and treatment of COVID-19 and possible adverse effects and important information related to drugs used for COVID-19. For future preparedness and readiness, new laws and legislations should be constituted. Besides, emergency teams and budgets should be prepared as well.

The emergence of an unprecedented pandemic SARS-COV-2 caused perplexed in the medical community because of a high infection rate and rising mortality among COVID-19 patients. Till now, there is no particular treatment for the disease; nevertheless, there is an extensive effort from scientists to find out an immediate therapeutic plan to show how to deal with the current situation. One of the solutions currently presented is Convalescence plasma (CP). Through this narrative review, we will shed light on CP's efficiency as a therapeutic agent for COVID-19, especially there is no proven vaccine or antiviral available up to date. CP could be considered one of the therapeutic approaches, but some limitations are still considered before it is established as a therapeutic agent. Along with evaluating CP from blood donors, the plasma companies could take future steps by manufacturing a target dose of globulins that contain standardized antibody, to reach the terms of health setting administering therapy.
Morphology, Food and Feeding Habit of Goby Fish, Parachaeturichthys ocellatus from the Creeks of Mumbai
Authors: Panicker Bindu
Published: November 2020

Goby fish Parachaeturichthys ocellatus, native to the creeks of Mumbai coast forms a major part of creek fishery for the fishing community inhabiting areas near the creeks. The food and feeding habits of the fish were studied by collecting fish samples every month in from June 2010 to September 2011 from the creeks of Mumbai. The length of the fishes studied ranged between 66mm to 185mm.The body morphology of fish revealed it to be carnivorous benthic and predatory fish. The gut contents of the fish showed the presence of crustaceans as basic food, mollusc and pisces formed the secondary food while detritus formed obligatory food and planktons and other miscellaneous food (larvae of insects, worms, rotiferons, dinoflegellates foraminiferons etc.) were incidental food. An analysis of seasonal variation in food preference and feeding intensity reveal that the male and female P.ocellatus had the same preference throughout the seasons but was different for the juveniles. In P.ocellatus cannibalism was observed, but its occurrence was not regular in the general diet. The relative gut length was 0.68 in male, 0.70 in female and 0.79 in juvenile. The empty guts of P.ocellatus seem to indicate predatory mode of feeding. P.ocellatus occupy the position of secondary and tertiary consumers in the food chain determined by the size and type of the food consumed by the fish.

Published: November 2020

Forming intellectually autonomous and active citizens is a major goal of education. Several areas of autonomy can be identified in education, such as school autonomy, curriculum autonomy, educators' autonomy, and the formation of autonomous citizens. The development of intellectual autonomy is realized, first and foremost, through the content of social studies and political literacy within an educational context of democratic principles of operation. The aim of this paper is to explore the concept of intellectual autonomy and the parameters by means of which intellectual autonomy is fostered through formal education. This paper involves a theoretical meta-analysis of the subject. It is concluded that school constitutes a primary context for developing political literacy, which achieves its goal by being able to shape intellectually autonomous and active citizens who can understand the significance of collective social action and gain self-fulfillment.
What Identity is Formed by the Russian School Today
Authors: Proskurina Anna
Published: November 2020

The paper raises the problem of the content and direction of the Russian educational policy regarding schoolchildren’s identity formation. The quality of identity is considered as a special determinacy of the individual’s relationship with other people and with social subjects. Two theoretical paradigms of human identity are distinguished in the paper and the basic characteristics of these paradigms are defined. The content analysis of the Russian Federal Public Educational Standards (FGOS) is performed in order to reveal the direction of identities formation that these standards entail. It is shown that modern Russian educational policy requests only one kind of identity, viz. the formation of a functionally acting member of society. The direct and the probable consequences of such policy are indicated in the article.

The purpose of this paper is to identify about the print-based media learning. The paper discusses about the development, characteristic, types and the advantages disadvantages of the print based media learning. In a teaching and learning process, two very important elements are teaching methods and learning media. These two aspects are interrelated. The choice of a particular teaching method will affect the appropriate type of learning media, although there are various other aspects that must be considered in choosing learning media, including learning objectives, types of tasks and responses expected by students and student characteristics. Even so, it can be said that one of the main functions of learning media is as a teaching aid that influences the climate, conditions, and learning environment that are organized and created by the teacher.

Abstract. Aerosol measurements over the Southern Ocean have been identified as critical to an improved understanding of aerosol-radiation and aerosol-cloud interactions, as there currently exists significant discrepancies between model results and measurements in this region. Previous springtime measurements from the East Antarctic seasonal ice zone revealed a significant increase in aerosol number concentrations when crossing the atmospheric polar front into the Polar cell. A return voyage in summer 2017 made a more extensive range of aerosols measurements, including in particular aerosol number concentrations and submicron size distributions. Again, significantly greater aerosol number concentrations were observed in the Polar cell than in the Ferrel cell. Unlike the previous spring voyage however, the polar front was unable to be identified by a step change in aerosol concentration. A possible explanation is that atmospheric mixing across the polar front occurs to a greater degree in summer, therefore weakening the atmospheric boundary at the front. This atmospheric mixing in summer complicates the determination of the polar front location. These changes, together with the increased source of precursors from phytoplankton emissions, are likely to explain the seasonal differences observed in the magnitude of aerosol populations between the Ferrel and Polar cell. In the present analysis, meteorological variables were used to identify different air-masses and then aerosol measurements were compared based on these identifications. CN3 concentrations measured during wind directions indicative of Polar cell airmasses (median 594 cm−3) were larger than those measured during wind directions indicative of Ferrel cell air (median 265 cm−3). CN3 and CCN concentrations were larger during periods where the absolute humidity was less than 4.3 gH2O/m3, indicative of free tropospheric or Antarctic continental airmasses, compared to other periods of the voyage. These results indicate that a persistently more concentrated aerosol population is present in the Polar cell over the East Antarctic seasonal ice zone, although the observed difference between the two cells may vary seasonally.
Unshielded precipitation gauge collection efficiency with wind speed and hydrometeor fall velocity. Part I: modelling results
Authors: Hoover Jeffery , Sullivan Pierre E. , Joe Paul I. , Earle Michael E.
Published: November 2020

Abstract. A new method for assessing collection efficiency using wind speed and hydrometeor fall velocity is presented for the unshielded Geonor T-200B3 precipitation gauge based on computational fluid dynamics results. Time-averaged Navier–Stokes simulations with a k–e turbulence model were used to determine the airflow around the gauge for 0 to 10 m s−1 wind speeds. Hydrometeor trajectories and collection efficiencies were determined using Lagrangian analysis for spherical 10 hydrometeor fall velocities between 0.25 to 10 m s−1 for rain (0.01–3.9 mm diameter), wet snow (0.2–21 mm diameter), dry snow (0.2–7.1 mm diameter), and ice pellets (1.5–4.3 mm diameter). The model results demonstrate that gauge collection efficiency strongly depends on both wind speed and hydrometeor fall velocity. Collection efficiency differences for identical hydrometeor fall velocities are within 0.05 for wind speeds less than 4 m s−1, despite differences in hydrometeor type, diameter, density, and mass. An empirical expression for collection efficiency with dependence on wind speed and fall velocity is 15 presented based on the numerical results, giving a RMSE of 0.03 for dry snow, wet snow, and rain, for wind speeds between 0 and 10 m s−1. The use of fall velocity captures differences in collection efficiency due to different hydrometeor types and sizes, and can be broadly applied even where the precipitation type may be unknown or uncertain. Results are compared to previous models and good model agreement with experimental results is demonstrated in Part II.
Unshielded Precipitation Gauge Collection Efficiency with Wind Speed and Hydrometeor Fall Velocity. Part II: Experimental Results
Authors: Hoover Jeffery , Earle Michael E. , Joe Paul I.
Published: November 2020

Abstract. Five collection efficiency transfer functions for unshielded precipitation gauges are presented that compensate for wind-induced collection loss. Three of the transfer functions presented are dependent on wind speed and precipitation fall velocity, and were derived through computational fluid dynamics modelling in Part 1 (CFD function) and from measurement data (HE1 function with fall velocity threshold and HE2 function with linear fall velocity dependence). These functions are evaluated alongside universal (KUniversal) and site-specific (KCARE) transfer functions with wind speed and temperature dependence. Their performance was assessed using 30-minute precipitation event accumulations reported by unshielded and shielded Geonor T-200B3 precipitation gauges over two winter seasons. The latter gauge was installed in a Double Fence Automated Reference (DFAR) configuration comprising a single-Alter shield within an octagonal, wooden double fence. Estimates of fall velocity were provided by a Precipitation Occurrence Sensor System (POSS). The CFD function reduced the RMSE (0.08 mm) relative to KUniversal, KCARE, and the unadjusted measurements, with a bias error of 0.011 mm. The HE1 function provided a RMSE of 0.09 mm and bias error of 0.006 mm, capturing well the collection efficiency trends for rain and snow. The HE2 function better captured the overall collection efficiency, including mixed precipitation, resulting in a RMSE of 0.07 mm and bias error of 0.006 mm. The improved agreement demonstrates the importance of fall velocity for collection efficiency.

Authors: Hinarejos Martín Nuria
Published: November 2020

La presencia de españoles en el continente americano ha sido objeto de atención para muchos investigadores durante las últimas décadas del siglo XX. Son abundantes las publicaciones sobre las listas de pasajeros que se trasladaron a América desde mediados del siglo XVI. El objeto de este trabajo es confirmar la presencia de más de una docena de ingenieros militares en la construcción del sistema defensivo de Extremadura y Puerto Rico, cuya labor ha pasado desapercibida para la mayoría de los expertos en la materia.
Kawanabe Kyōsai: espectador de la construcción de una nueva identidad japonesa
Authors: Romero Leo Jaime
Published: November 2020

Tras un período de dos siglos y medio de hermetismo, Japón abrió finalmente sus puertos al mundo tras la llegada de una pequeña flota norteamericana enviada a sus costas en 1854. Este acontecimiento marcó el inicio del período Meiji (1868-1912) y con él, bajo la influencia occidental, del inicio de la modernización nipona. Así, durante los primeros años del nuevo período, Japón se sumió en un proceso de auto-occidentalización sin precedentes que sin duda estuvo marcado por la amenaza colonial en que Asia se encontraba inmersa desde hacía décadas. Este desconcertante contexto en el que Japón abrazó a Occidente y comenzó a repudiar sus propias raíces culturales fue retratado por Kawanabe Kyōsai en obras que destilaron crítica y humor por igual tal y como evidenciaron ejemplos como Escuela para demonios (1874). Kyōsai fue cronista de uno de los momentos decisivos de la historia nipona en el que el archipiélago asiático se encontró a caballo entre su inmediato pasado feudal y la influencia extranjera proveniente de Europa y Estados Unidos.
Mapping the Cultural Heritage of Dissent. New Sources, New Knowledge and New Narrative(s) on European Identity
Authors: Petrescu Cristina
Published: November 2020

El proyecto COURAGE ha creado una base de datos electrónica de acceso abierto que recopiló nuevas fuentes, resumió nuevos conocimientos y creó nuevas narrativas sobre un patrimonio cultural europeo hasta ahora dividido: el legado de la disidencia bajo las dictaduras comunistas en Europa Central y Oriental. El equipo rumano de COURAGE ha resaltado un nuevo sentido de ser europeo, que fue experimentado por muchas personas comunes que crearon significados cotidianos y prácticas culturales como si vivieran en un país libre. Esta identificación con Europa se refleja en colecciones privadas previamente desconocidas creadas por aquellos que preveían estrategias de oposición a las dictaduras comunistas que habían rechazado los valores fundamentales que sustentan la Unión Europea: estado de derecho, derechos humanos, libertades civiles, etc. Los valores opuestos se reflejan en las colecciones creadas por la policía secreta comunista rumana, la Securitate, que recuerdan un pasado europeo no democrático y advierten sobre el peligro de olvidarlo bajo la presión de los desafíos actuales que enfrenta el proyecto europeo.
Los «grupos de afinidad», actores del proceso cultural y societario ácrata (España, 1930-1939)
Authors: Lora Medina Alejandro
Published: November 2020

El objetivo del presente artículo es analizar las características y la importancia de los grupos de afinidad anarquista en los años treinta dentro del movimiento libertario español. La heterodoxia ácrata encuentra en estos grupos de ámbito local y autonomía de acción la vía para crear una militancia combativa y revolucionaria. El fomento de la cultura se convierte en el pilar central de la actuación de estos colectivos. Analizaremos el origen, función, sentido e idiosincrasia de la estructura organizativa básica del movimiento libertario español, y cómo los cambios políticos iniciados tras el inicio de la Guerra Civil permitiría que la FAI convirtiera a los grupos de afinidad en un instrumento para conseguir mayor influencia y poder frente a otros partidos o colectivos.
Comentario. Releer a Bowman, repensar la Geopolítica
Authors: Agulló Juan
Published: November 2020

este artículo comenta Geography versus Geopolitics, redactado en 1942 por Isaiah Bowman y publicado por la Geographical Review. En estas líneas se argumenta que dicho texto, pese a ser producto de su militancia en la Geografía y por encima de ello, de un contexto político complejo, si es releído con una perspectiva crítica, puede ser considerado un interesante referente para la Geopolítica contemporánea. De hecho, lo que Bowman pretendió con su trabajo fue deconstruir la vieja Geopolitik alemana, una tradición ideológica que condensó, en sus supuestos y procedimientos, la mayor parte de defectos epistemológicos del pensamiento clásico, todavía detectables en algunas formas actuales de concebir la Geopolítica.

Turismo rural comunitario: una alternativa para el desarrollo socioeconómico de la comunidad El Ostional, San Juan del Sur, Rivas, Nicaragua
Authors: Arróliga Montenegro Carmen Anielka , Zamora Jarquín Francisco J.
Published: November 2020

El turismo rural comunitario es una alternativa social y económica al turismo tradicional. Este estudio pretende comprobar si el modelo de desarrollo turístico rural comunitario aplicado en la comunidad El Ostional se está gestionando de manera correcta y comprobar de esta forma si hay impacto en la mejora de la calidad de vida de la población, promoviendo el rescate de la identidad cultural. Para conocer estos aspectos es necesario describir los factores socioeconómicos como organización, equidad de género, y función de la mujer, capacitación, economía comunitaria y la vinculación del turismo con otras fuentes de ingreso y posteriormente evaluar su modelo turístico rural comunitario, para esto se aplicó la metodología de Vigilancia en Sitios Centinela utilizada por el Centro de Investigación de Enfermedades Tropicales que combina métodos cuantitativos y cualitativos, utilizando como unidad de análisis los hogares para las variables sociales y las fuentes de ingresos para variables económicas. El Turismo Rural Comunitario en El Ostional es cada vez más importante para el municipio de San Juan del Sur, tanto que, los proyectos del gobierno y de la entidad reguladora del turismo, tienen a la comunidad identificada como el principal atractivo para así descongestionar la afluencia de turistas a San Juan del Sur. El modelo turístico de El Ostional permite generar beneficios socioeconómicos directamente a la cooperativa de turismo e indirectamente al resto de los pobladores.
Learning English Rhetoric and Composition as A Vietnamese Student
Authors: Le Phuong N , Hang Dao Thi Thu , Ha Pham Thi , Tien Nguyen Thi Kieu
Published: November 2020

This study centers around Vietnamese students, with a comparison with East and Southeast Asian students who share the same cultural idea, at higher education level who want to acquire better writing skills in English in and out of academic settings. Since English is not the students' first language, they normally craft an essay from the vocabulary that they know. This is understandable, but a good piece of writing in standard American English is not supposed to be traced word by word. Understanding this fact in-depth and practicing it regularly is the core requirement for English major students. In return, they can join any workplace with their strong writing skills that they have to acquire during their undergraduate years, or more if they attend graduate schools. This group of students is known to be timid since they were raised in a collectivistic community in which many of them make their higher education choices based on firstly the current trend, then what is suitable for them. Thus, by making a bolder choice of declaring English as a major, double major, or minor, they could have better insight into English rhetoric and composition to apply them as a multi-meaning sign to their writings properly.

Suicides Before, During, and After Daylight Savings Time in the United States
Authors: Popoli Gary , Curry Katelyn
Published: November 2020

This study was designed to investigate differences in the number of suicides committed in the United States before, during, and after daylight savings time (DST). Conflicting results in the literature suggest both a positive and negative effect of DST in the physical, mental, behavioral aspects society. As a result, some states are proposing legislation to abolish DST while others are trying to make DST permanent. This study is designed to investigate whether DST has a positive negative, or no effect on the frequency of suicide. Archival data from a governmental public database containing the total number of suicides by year and month from 2000-2017 was used. Daylight savings time was defined as the months of March through October while non-DST consisted of the remaining 4 months. The data were organized into 3 groups of 4 months beginning in November, 2007 and ending in October, 2017. The results demonstrated a statistically significant increase in suicides during DST. Most suicides were committed during July-October (M = 74.69, SD = 68.86), compared to March-June (M = 73.56, SD = 67.89), and November-February (M = 67.00, SD = 61.41). Despite disagreement in the literature, this study would suggest eliminating DST altogether. These results support other evidence which suggest a detrimental effect of DST, especially with respect to the psychological and behavioral aspects of public health. Nevertheless, there is still a need for more research to determine the impact of these one hour time shifts in the Spring and Fall.
