Published: October 2019

Despite dynamic inputs, neuronal circuits maintain relatively stable firing rates over long periods. This maintenance of firing rate, or firing rate homeostasis, is likely mediated by homeostatic mechanisms such as synaptic scaling and regulation of intrinsic excitability. Because some of these homeostatic mechanisms depend on transcription of activity-regulated genes, includingArcandHomer1a, we hypothesized that activity-regulated transcription would be required for firing rate homeostasis. Surprisingly, however, we found that cultured mouse cortical neurons from both sexes grown on multi-electrode arrays homeostatically adapt their firing rates to persistent pharmacological stimulation even when activity-regulated transcription is disrupted. Specifically, we observed firing rate homeostasis inArcknock-out neurons, as well as knock-out neurons lacking the activity-regulated transcription factors AP1 and SRF. Firing rate homeostasis also occurred normally during acute pharmacological blockade of transcription. Thus, firing rate homeostasis in response to increased neuronal activity can occur in the absence of neuronal-activity-regulated transcription.

SIGNIFICANCE STATEMENTNeuronal circuits maintain relatively stable firing rates even in the face of dynamic circuit inputs. Understanding the molecular mechanisms that enable this firing rate homeostasis could potentially provide insight into neuronal diseases that present with an imbalance of excitation and inhibition. It has long been proposed that activity-regulated transcription could underlie firing rate homeostasis because activity-regulated genes turn on when neurons are above their target firing rates and include many genes that could regulate firing rate. Surprisingly, despite this prediction, we found that cortical neurons can undergo firing rate homeostasis in the absence of activity-regulated transcription, indicating that firing rate homeostasis can be controlled by non-transcriptional mechanisms.
Music and the Making of the Cosmonaut Everyman
Authors: Cornish Gabrielle
Published: October 2019

This article repositions the space race as a sonic phenomenon by analyzing music and sounds related to the Soviet space program. Early triumphs such as the orbit of Sputnik I in 1957, Yuri Gagarin’s groundbreaking orbital flight in 1961, and Valentina Tereshkova’s success as the first woman in space in 1963 epitomized the complexities of the cultural Cold War and the utopian underpinnings of the Thaw. Space, the ultimate nonaligned sphere, was a new world for the planting of real and ideological flags. At the same time, these successes were key to reimagining the ideals of Soviet citizenship and national identity in the post-Stalin era. Heating up at a moment of great change and consequence, the space race provides an inroad to examine how music, media, and sound helped spread these emerging values. Drawing on the popular press, radio broadcasts, and variety television performances, this article demonstrates how music was used to humanize the cosmonauts and promote a new personal ethics—one that prized approachability and humility alongside heroism and bravery. The divergent ways that composers and performers celebrated Gagarin and Tereshkova reveal a complex politics of gender during the Thaw. Gagarin, the conqueror, was revered in marches extolling his colonizing feats; Tereshkova, the homemaker, was celebrated with romances and tales of domesticity. By demonstrating the prevalence of new media and the power of participatory practices in the sonic space race, this article contributes to our understanding of the cultural Cold War as a lived and performed experience.
Midnight salivary cortisol secretion associated with high systolic blood pressure in type 1 diabetes
Authors: Melin Eva Olga , Hillman Magnus , Landin-Olsson Mona
Published: October 2019

Objective

To explore associations between high midnight salivary cortisol (MSC) secretion and high blood pressure (BP) in type 1 diabetes (T1D).

Methods

Cross-sectional study of 196 adult patients with T1D (54% men). Associations between high MSC (≥9.3 nmol/L) and high systolic BP (>130 mmHg), and high diastolic BP (>80 mmHg) were explored for all patients, users and non-users of antihypertensive drugs (AHD). Adjustments were performed for age, sex, diabetes-related variables, p-creatinine, smoking, physical inactivity, depression and medication.

Results

The prevalence of high MSC differed between patients with high and low systolic BP in all 196 patients: 39 vs 13% (P = 0.001); in 60 users of AHD: 37 vs 12% (P = 0.039), and in 136 non-users of AHD: 43 vs 13% (P = 0.012). Significant associations with high systolic BP were for all patients: physical inactivity (adjusted odds ratio (AOR) 6.5), high MSC (AOR 3.9), abdominal obesity (AOR 3.7), AHD (AOR 2.9), age (per year) (AOR 1.07), and p-creatinine (per µmol/L) (AOR 1.03); for 60 users of AHD: high MSC (AOR 4.1) and age (per year) (AOR 1.11); for 136 non-users of AHD: abdominal obesity (AOR 27.4), physical inactivity (AOR 14.7), male sex (AOR 9.0), smoking (AOR 7.9), and age (per year) (AOR 1.08). High MSC was not associated with high DBP.

Conclusions

In adult patients with T1D, high systolic BP was associated with physical inactivity, high MSC secretion, abdominal obesity, p-creatinine, age, and AHD, the latter indicating treatment failure.

Breast cancer is the most common invasive neoplasia, and the second leading cause of the cancer deaths in women worldwide. Mammary tumorigenesis is severely linked to obesity, one potential connection is leptin. Leptin is a hormone secreted by adipocytes, which contributes to the progression of breast cancer. Cell migration, metalloproteases secretion, and invasion are cellular processes associated with various stages of metastasis. These processes are regulated by the kinases FAK and Src. In this study, we utilized the breast cancer cell lines MCF7 and MDA-MB-231 to determine the effect of leptin on FAK and Src kinases activation, cell migration, metalloprotease secretion, and invasion. We found that leptin activates FAK and Src and induces the localization of FAK to the focal adhesions. Interestingly, leptin promotes the activation of FAK through a Src- and STAT3-dependent canonical pathway. Specific inhibitors of FAK, Src and STAT3 showed that the effect exerted by leptin in cell migration in breast cancer cells is dependent on these proteins. Moreover, we established that leptin promotes the secretion of the extracellular matrix remodelers, MMP-2 and MMP-9 and invasion in a FAK and Src-dependent manner. Our findings strongly suggest that leptin promotes the development of a more aggressive invasive phenotype in mammary cancer cells.
Sexually dimorphic gene expression and neurite sensitivity to estradiol in fetal arcuate Kiss1 cells

Published: October 2019

Kiss1 neurons of the arcuate (ARC) nucleus form an interconnected network of cells that communicate via neurokinin B (encoded by Tac2) and its receptor (encoded by Tacr3) and play key roles in the control of the reproductive axis through sex hormone-regulated synthesis and release of kisspeptin peptides (Kp, encoded by Kiss1). The aim of this study was to determine whether the Kiss1 cell population of the ARC already displays sexually dimorphic features at embryonic age E16.5 in mice. At this time of development, Kiss1-GFP- and Kp-immunoreactive cell bodies were restricted to the ARC and not found in the pre-optic area (POA). The Kiss1-GFP cell population was identical in size between sexes but had significantly lower Kiss1, Tac2, and Tacr3 mRNA levels and lower Kp-ir fiber density in the POA in male compared to female fetuses. Receptors for androgen (Ar) and estrogen (Esr1, Esr2, Gpr30) and the Cyp19a1 gene (encoding the estradiol-producing enzyme aromatase) transcripts were also detected in fetal ARC Kiss1-GFP cells with significant sex differences for Ar (higher in males) and Esr1 (higher in females). Functional studies on primary cultures of sorted fetal Kiss1-GFP cells revealed a significant negative effect of estradiol treatment on neurite outgrowth on the fourth day of culture in the female group specifically. We conclude that the ARC Kiss1 cell population is already sexually differentiated at E16.5 and that its morphogenetic development may be particularly vulnerable to estradiol exposure at this early developmental time.

Published: October 2019

El objetivo del presente artículo de revisión es analizar los principales factores de riesgos psicosociales dentro de los diferentes ambientes sujetos al trabajo que pueden sufrir los empleados, afectando e influyendo los contextos donde se desarrolla, basándose en los resultados obtenidos de investigaciones realizadas a nivel nacional e internacional. Además, se dejó el campo abierto para la búsqueda de factores de riesgos psicosociales, puesto que ellos pueden encontrarse en cualquier tipo de entorno. La metodología se basa en una recopilación de literatura científica, en relación con el tema de factores de Riesgos psicosociales (RPS), teniendo en cuenta los criterios de inclusión; de habla hispana a nivel nacional e internacional, eje temático, antigüedad y artículos publicados en revistas científicas, la documentación requerida para este artículo se tomó de las bases de datos Scielo, Base de Datos de la Universidad Cooperativa de Colombia, Redalyc y ProQuest. Con una muestra de cuarenta artículos científicos incluidos en la revisión literaria. Los 40 artículos incluidos en la elaboración de este documento, mediante su análisis bibliográfico, consideraban a los RPS, como el factor problemático de las organizaciones, debido a que los altos percentiles de exposición a los riesgos psicosociales cada vez son mayores; la falta de programas o evaluación del riesgo psicosocial coacciona la incidencia de problemas en la salud de los trabajadores de carácter físico y mental. Por ende, gran parte de los artículos estudiados definen a los riesgos psicosociales como el factor generador de enfermedades silenciosas, que, no tratadas a tiempo, generan daños irreversibles en la salud física y psicológica del individuo, y desequilibrio del estado de bienestar físico y mental. Los factores de riesgo psicosociales se han convertido en el mayor problema de ausentismo laboral en las organizaciones de índole privado y público, ceñido a esto, la implementación de métodos de evaluación de RPS en las empresas, de algunos sectores comerciales; consideran innecesaria la aplicación de instrumentos de detección de los factores psicosociales. El proceso aplicativo es vital, para reconocimiento oportuno de los factores de riesgo psicosocial y así poder implementar estrategias, programas de mitigación de los riesgos psicosociales, logrando de esta forma grados de exposición al riesgo menores, y generar espacios de trabajo seguros y sanos que no afectarán la salud física y mental de los trabajadores.
El oficio del historiador y las nuevas formas de hacer historia: De la teoría a las prácticas
Authors: Pabón Serrano Oscar Mauricio , Lizcano Herrera Dayana Lucía , Joya Jiménez Edna Lucía
Published: October 2019

El siguiente artículo intenta precisar algunos aspectos metodológicos, conceptuales y temáticos que delinearon el desarrollo de la investigación y la ciencia histórica a partir de la segunda mitad del siglo XX, época en la que se tomó conciencia de la necesidad de comprender desde las ciencias sociales todos los ámbitos de la actividad humana y de superar las barreras trazadas por la historia política de corte tradicional. Este movimiento de renovación se concretó en la corriente historiográfica conocida como la historial social, un enfoque que echó mano de las nuevas formas, objetos de estudio, teorías sociales y fuentes de información, replanteando el modo como se investiga el pasado, considerando el estudio de otros actores sociales y de los diferentes fenómenos que implican la vida en comunidad. En la parte final del artículo se reseñan tres investigaciones que ilustran el interés de los historiadores por los “otros” temas que, como la enfermedad o los estereotipos femeninos, llamaron la atención de la historia social.

Por meio do uso de plataformas digitais como o portal Wiki Aves, o interesse público pela atividade de observação de aves (birdwatching) tem gerado dados que têm sido úteis aos docentes, sobretudo para o desenvolvimento de práticas pedagógicas ao ar livre, com vista ao conhecimento e à conservação das espécies de aves locais.  Sabe-se que essa atividade, além de ser dinâmica e prazerosa, pode prestar enormes contribuições ao desenvolvimento sustentável quando associada à educação ambiental. Com base nos referenciais teóricos que enfatizam o uso de mídias digitais e novas tecnologias na prática educacional, elaboramos uma proposta pedagógica que, quando aplicada, visa contribuir para alcançar os objetivos preconizados pelas diretrizes dos programas nacionais de educação ambiental. O presente artigo propõe uma metodologia pedagógica tendo por base o portal Wiki Aves para um entendimento da composição da avifauna do município do Rio de Janeiro e projeta como esse conhecimento pode direcionar a realização de atividades pedagógicas envolvendo práticas de educação ambiental. As atividades propostas reforçam o valor da observação de aves como um incentivo para o ensino de ciências e/ou biologia, podendo contribuir para o conhecimento científico por meio da prática cidadã por alunos de diversos segmentos escolares.
How to overcome taxonomical problems in the study of Internet use disorders and what to do with “smartphone addiction”?
Authors: Montag Christian , Wegmann Elisa , Sariyska Rayna , Demetrovics Zsolt , Brand Matthias
Published: October 2019

Aims: The present theoretical paper introduces the smartphone technology as a challenge for diagnostics in the study of Internet use disorders and reflects on the term “smartphone addiction.”

Methods: Such a reflection is carried out against the background of a literature review and the inclusion of Gaming Disorder in ICD-11.

Results: We believe that it is necessary to divide research on Internet use disorder (IUD) into a mobile and non-mobile IUD branch. This is important because certain applications such as the messenger application WhatsApp have originally been developed for smartphones and enfold their power and attractiveness mainly on mobile devices.

Discussion and conclusions: Going beyond the argumentation for distinguishing between mobile and non-mobile IUD, it is of high relevance for scientists to better describe and understand what persons are actually (over-)using. This is stressed by a number of examples, explicitly targeting not only the diverse contents used in the online world, but also the exact behavior on each platform. Among others, it matters if a person is more of an active producer of content or passive consumer of social media.
Experimental determination of the shear strength of peat from standard undrained triaxial tests: correcting for the effects of end restraint
Authors: Muraro Stefano , Jommi Cristina
Published: October 2019

Conventional triaxial tests on peats are strongly criticised due to the very high shear strength parameters obtained from standard data elaboration, leading to unrealistic factors of safety when used in geotechnical design and assessment. Various operational approaches have been proposed in the literature to overcome this difficulty; however, they seem to lack consistent mechanical background. Some of the issues related to the shear strength evaluation of peats from triaxial tests come from the non-uniform stress and strain states developing in the samples well before failure is attained, due to end restraint effects. Undrained triaxial compression tests were performed on reconstituted peat to examine the influence of end restraint on the deviatoric stress, excess pore pressure and deviatoric strain response. Samples were tested with standard rough end platens and with modified platens to reduce the friction between the sample and bottom and top caps. Four different initial height-to-diameter ratios were examined, to reduce the consequences of rough end platens on the sample response. The results indicate that end restraint contributes dramatically to overestimating the shear strength of peat, due to the increase in both the calculated deviatoric stress and the measured excess pore pressure at the bottom of the sample. Suggestions are given to quantify the influence of end restraint in the interpretation of standard data, in an attempt to suggest viable procedures to determine more reliable effective and undrained shear strength parameters from standard triaxial tests.
The Price of Sadness: Comparison between the Netherlands and South Africa
Authors: Mukheibir Andre , Mitchell Gregory
Published: October 2019

Bereavement can be a precipitating and perpetuating factor for various psychiatric injuries. However, the normal experience of bereavement also causes significant disruption and stress in an individual’s psychosocial functioning. Both in the Netherlands and South Africa, a clear distinction is drawn between sadness and psychiatric injury. Dutch law, until recently, did not make provision for compensation for sadness, but only for psychiatric injury. This has changed with the coming into operation of the Wet Affectieschade on 1 January 2019. In terms of South African law, there is no claim for compensation for sadness or bereavement. The authors are of wby bereavement, sadness or grief resulting from bereavement causes significant distress and a continuum exists between normal and complex bereavement where a clear distinction does not exist. South African courts should, therefore, bear this is mind when in actions for compensation for non-patrimonial loss for bereavement.

EFL Instructors’ Performance Evaluation at University Level: Prescriptive and Collaborative Approaches
Authors: Tawalbeh Thaer Issa
Published: October 2019

The present paper aims to investigate EFL instructors’ performance at university level according to prescriptive and collaborative approaches in supervision. In order to achieve this target, the researcher addressed three questions. The first investigates instructors’ level of performance. The second and third questions aimed to identify instructors' points of strength and action points. In this regard, the researcher developed an observation checklist (Appendix A) for supervisors to use when observing teachers'. He also developed observation guidelines for supervisors to make sure they are following the collaborative approach of supervision (Appendix B). The data were analyzed using descriptive statistics, including means, standard deviation and percentages to answer the first question. To answer the second and third questions, the researcher used content analysis to synthesize the supervisors' feedback given to instructors regarding their points of strengths and action points. The results showed that the instructors' performance was either satisfactory or outstanding based on the supervisors' observation, which could be due to the professional development program conducted to develop their teaching competencies. In addition, the instructors showed themselves competent in other areas related to motivating students and providing them with constructive feedback. However, some instructors still need to develop their competencies in areas such as classroom management and teacher talk time. These have been summarized according to their frequency of occurrence in tables 2 and 3. Based on the results, the researcher drew a number of conclusions and recommendations.
A Corpus-based 3M Approach to the Teaching of English Unaccusative Verbs
Authors: Mo Junhua
Published: October 2019

This study attempts to take a corpus-based approach to teaching English unaccusative verbs to Chinese students in a 3M way, which is a combination of implicit and explicit instructions. It finds that Chinese students welcome the corpus-based approach and are excited to see the concordance lines retrieved from the Chinese English Learner Corpus (CLEC). And they prefer explicit instructions by the teacher, which they think is insightful and useful. But they are not keen about figuring out the usages of the target words from the context, which they think is a bit boring. This suggests that Chinese students, who have been accustomed to being spoon-fed by their teachers, are not highly autonomous. This study concludes that the corpus-based 3M approach is in general effective for the teaching of English unaccusative verbs.
Recreating the Image of a “Chaste Wife”: Transitivity in Two Translations of Chinese Ancient Poem Jie Fu Yin
Authors: Tao Shilong
Published: October 2019

This article is a comparison on the recreating of the image of a “chaste wife” in two English translations of Chinese ancient poem Jie Fu Yin from the perspective of systemic functional linguistics (SFL). The linguistic choices of the poet and translators are measured from transitivity under experiential meaning of ideational metafunction. It has found that Hart tends to follow a creative and imaginative translation, thus creating a more enthusiastic even passionate image of a young “chaste wife” in a direct and explicit way, while Fletcher presents a clam and tender image of a mature “chaste wife” in a relatively implicit way. Besides, both translations reproduce the theme about love, but losing the political theme. It is argued that in translation, the lexico-grammatical choices will lead to variation in meanings and recreate different images of a same character, and the seemingly unconscious choices can be better understood based on the context of translation.

A Comparative Study of Features of Sorption of N-Buthylxanthate and Dibuthyldixanthogen Onto Metallic Supports and Rutile Using in situ Atomic Force Spectroscopy
Authors: Karacharov Anton A. , Likhatski Maxim N.
Published: October 2019

An interaction of potassium buthylxanthate and of dibuthyldixanthogen with metallic Ti, stainless steel and α-TiO2 surfaces was studied. Contact angle measurements by sessile drop technique showed that the treatment of initial substrate surfaces with potassium buthylxanthate aqueous solution or with dibuthyldixanthogen emulsion render them more hydrophobic. Using in situ atomic force spectroscopy, the sorption of surface active substances was shown to give rise to an increase in both adhesive force magnitude and the range within it acts at the approach of cantilever tip to the surface of both hydrophobic and hydrophilic samples. The maximum of both adhesive force and their range, up to 150 nm, took place in case of retract of cantilever tip from sample surface. Force curves are steeper, which related with the formation of nanobubbles on the surfaces of samples under study arising the longrange hydrophobic force of capillary origin. Dibuthyldixanthogen exhibited highly-active reagent properties inducing the formation of nanoscale gas structures on both hydrophobic and, in less extent, hydrophilic surfaces

The influence of hydrothermal conditions on synthesis of analcime and a composite material ZrO2- analcime as well as zirconomolybdate coverings with ion exchange properties was studied using narrow fractions of aluminosilicate microspheres with a high content of a glass phase (91-95 wt. %). The possibility to synthesize ZrO2-analcime composites of narrow particle size distributions with maximum of about 40 μm and 6 μm under hydrothermal treatment at 150 °С was demonstrated starting from microspheres with Si/Al=2.7 and applying different regimes of a reaction mixture agitation. A microsphere material of a “core-shell” type such as ZrMo2O7(OH)2(H2O)2@(SiO2-Al2O3)glass with the nanostructured covering was prepared. Sorption properties of the materials regarding Nd3+, Sr2+ and Cs+ were studied under equilibrium conditions by means of determination of sorption isotherms and their fitting by the Langmuir model. Sorption parameters were determined including distribution coefficients which reach the values of 104−105 mL/g
Retos institucionales y no institucionales para el partido Fuerza Alternativa Revolucionaria del Común (FARC) en las elecciones legislativas de 2018
Authors: Cabrera Nossa Irene Alejandra , Echandía Castilla Camilo
Published: October 2019

Este artículo examina los alcances y retos de la participación política del partido Fuerza Alternativa Revolucionaria del Común (FARC) a partir de la dinámica electoral y la evolución del conflicto armado y la violencia. La reflexión sobre la participación política de la FARC en el ámbito nacional se basa en los aportes de la literatura especializada en reincorporación política y en los resultados electorales para el Congreso de 2018. A través del software Arcgis se analizan los niveles de votación por la FARC en relación con la presencia de grupos armados, economías criminales y el asesinato de líderes, variables determinantes del bajo o alto apoyo electoral. Con la suma de estos elementos, esta investigación identifica varios factores institucionales y no institucionales que han incidido en la reincorporación política de las FARC-EP. Se subraya cómo, aunque las provisiones políticas para el acceso transitorio de la FARC a curules en el Congreso resultaron razonables para lograr una salida negociada a la guerra, la baja votación por el nuevo partido revela un futuro incierto para su continuidad, a pesar de las oportunidades electorales establecidas por el Acuerdo de Paz.

The Utilitarian vs. Hedonic Teacher Acceptance of ICT Use
Authors: LIMONE Pierpaolo , SINATRA Maria , TANUCCI Giancarlo , MONACIS Lucia
Published: October 2019

This research examined which teachers’ cognitive and motivational factors, i.e., constructivist beliefs, intrinsic and extrinsic motivation, perceived ease of use and behavioral intention, fostered an effective and satisfactory integration of technology into educational practices. 374 Italian teachers (MAge = 38.69, SD = 5.30; F = 198) attending a training course in ICT were divided into two groups: the first with less than 20 years of teaching experience, the second with more than 21 years. Participants completed a battery of questionnaires that comprised a socio-anagraphic section, the Teacher’s Beliefs Scale-Constructivist Teaching, the Intrinsic Motivation-Computer Enjoyment Scale, the Extrinsic Motivation-Perceived Usefulness, the Perceived Ease of Use Scale, the Behavioural Intention to Use Computer Scale, the ICT Class Use Scale. Descriptive and causal analyses (correlation and stepwise regression) were applied to the data. Results showed differences between the groups in the scores of Perceived usefulness and Behavioral intention to use computer. Bivariate associations with Classroom use of technology were strong and positive. Moreover, teachers’ Beliefs were strongly related to all motivational factors. Model 5 of regression analysis explained 46.9% of the variance in ICT Class use and indicated the highest value of Perceived enjoyment, thus highlighting the teachers’ hedonic-oriented motivation.

Authors: CETINKAYA Levent , SUTCU Selim Soner
Published: October 2019

The purpose of this study is to determine the effects of the multimedia annotations which were sent through instant messaging application WhatsApp on students’ success in English vocabulary acquisition together with their opinions on the educational use of WhatsApp and the multimedia annotations. In the study, mixed method model, which combines both quantitative and qualitative data, was employed. Results of the variance analysis of the quatitative data indicated that the multimedia annotations sent through WhatsApp yielded a meaningful increase in students’ vocabulary acquisition. Multiple comparison test to identify the reason of this increase revealed that ‘Text+Picture+Audio’ and ‘Text+Picture’ multimedia annotations increased students’ vocabulary acquisition meaningfully when compared to other learning multimedia annotations. Although ‘Text+Audio’ multimedia annotation contributed to the success of students more than the students who received only ‘texts’, it wasn’t found meaningful. In the qualitative aspect of the study, students expressed their willingness to go on the treatment. They stated that similar researches in their other courses could be useful. They also added that they could learn unconsciously and expressed positive opinions towards the use of the pictures and audio annotations in particular. However, a few students reacted negatively againts the irrelevant posts and stated that the posts occupied a lot of space on their phones.
Comparing and Contrasting the Interactional Performance of Teachers and Students in Traditional and Virtual Classrooms of Advanced Writing Course in Distance Education University
Authors: ASADI Naeimeh , KHODABANDEH Farzaneh , YEKTA Razieh Rabbani
Published: October 2019

Since interaction provides the opportunity for students to share their ideas, thoughts, comments and feelings with their peers and teacher, it can be claimed that it is an integral component of learning. The present study applied the Sinclair and Coulthard’s interaction (IRF) (1975) model on the English learners of two traditional and virtual classes in order to investigate the differences between their writing scores in these two classes on the one hand, and the extent to which the IRF structure occurs in these two classes on the other hand. For this purpose, 79 and 20 intermediate level EFL learners were selected from the virtual and traditional classes of Payame Noor University (PNU). They were given the pre-test at the beginning and post-test after eight sessions of the same treatment in both classes by the same instructor. Their pre- and post-test scores were compared. The results indicated that there was a significant difference between the participants’ post-test scores in two classes in terms of three components of the intended six components of the five-paragraph essay. This study concluded that the participants in the virtual class performed better than their peers in the traditional one. Moreover, the number of interactions between the participants and teacher was more in the virtual class. Since the effect of interaction between the students and teacher on better performance and learning was shown in this study, other teachers can take into consideration the importance of interaction as well as technology for better teaching-learning process.
Survival and Risk Analysis in MOOCS

Published: October 2019

The most significant disadvantage in the use of MOOCs is their high drop out rates, which reaches between 88.3% and 90%. This research examined the desertion from 15 MOOCs, the following factors and their relation to desertion were assessed, characteristics of the students (gender, language, educational level, age, interest in the final certificate) and aspects of the courses (data lost at the time of registration, duration of the MOOC, course discipline, number of total questions and by evaluation). The results, based on survival analysis, indicate the probability of desertion is the highest on the first and last weeks of the MOOC. Our findings show that the probability of dropout is affected by the number of questions in each evaluation, the educational level of the participants, their age and their interest in the certificate. Missing data in the registration form was found to be associated with desertion being a significant pre-dictor of risk of quitting. Finally, the lack of interest in the certificate was found to be a predictor of the highest risk of dropping out. Possible strategies to reduce the desertion behavior at MOOCs are discussed.

Artykuł jest zwięzłym wprowadzeniem w problematykę wykorzystania modeli teoriogrowych w badaniach bezpieczeństwa narodowego. Podzielono go na cztery części. W części pierwszej omówiono podstawowe zagadnienia teoretyczne, tj.: podział na analityczną i behawioralną teorię gier, pojęcie racjonalności graczy, założenie o wspólnej wiedzy graczy o ich racjonalności, pojęcie równowagi Nasha, pojęcie efektywności w sensie Pareto oraz klasyfikacje gier. W części drugiej opisano pokrótce ewolucję teoriogrowych analiz bezpieczeństwa narodowego. Zwrócono uwagę na związki między rozwojem teorii gier a potrzebami militarnymi. W części trzeciej wskazano przykładowy sposób użycia modeli teorii gier w badaniach bezpieczeństwa narodowego. Szczegółowo omówiono stosunki handlowe przyjmujące schemat interakcji dylematu więźnia. W toku analiz przybliżono ogólny model dylematu więźnia, grę wyjściową definiującą rozpatrywany problem oraz jego rozwiązania w postaci gry iterowanej oraz metagry. Całość rozważań zwieńczyło podsumowanie.
Analizy wskazują następujące zalety stosowania modeli teoriogrowych w badaniach bezpieczeństwa narodowego: 1) modele teoriogrowe znacznie upraszczają analizowane interakcje, przez co pozwalają wniknąć w głąb procesów, wydobywając te cechy i związki, które do tej pory umykały badaczom; 2) stosowanie modeli teorii gier nie wymaga od badaczy znajomości skomplikowanych formalizmów matematycznych; 3) modele teorii gier umożliwiają identyfikację dylematów społecznych, czyli sytuacji, w których zachodzi sprzeczność krótkoterminowego interesu jednostki z długoterminowym interesem społecznym.
Expressions phraséologiques, les cas intermédiaires : entre automatismes énonciatifs et créativité linguistique
Authors: Krylyschin Marina
Published: October 2019

This paper presents the analysis of two nominal sentence paradigms that show the same formal and pragmatic characteristics, from two types of corpus corpora: comments in guestbooks and Blaise Cendrars’ poems. Such corpus types, having a phraseological aspect, reveal a creative process that can be described through Sechehaye’s « Imaginative syntax ». The paradigms Bonheur / regal / plaisir / irritation des yeux; Un bruit de basse-cour / de vaisselle et de frein / de waterchute / de chemin de fer, will be analysed from a syntactic and semantic perspective, to present how bonheur des yeux and bruit de chemin de fer are both the result of a creative linguistic process.
Les pragmatèmes d’affect, délimitation définitoire et propriétés sémantiques
Authors: Gharbi Najwa
Published: October 2019

Pragmatic phraseology has long been perceived as a marginal linguistic object. As a result, moves from total marginality to enlightenment by several more or less recent linguistic theories have occurred. This article proposes an examination of the syntactic, morphological and semantic compositional criteria of pragmatemes used to express an emotion. We also reflect on the interaction between co-text and context in the construction of the meaning of a ‘pragmatème’ of affect. We observe the influence of the elements of textual nature namely the co-text and the environment of the context on the meaning of a ‘pragmatèmes’.
Traduction des énoncés liés à une situation d’énonciation, les pragmatèmes
Authors: González Martín Carmen

Greeting someone with a Hello!, or finishing a letter with Sincerely, Yours truly, seems very easy for a native speaker. These expressions, basic in ordinary life communication, entail a lot of constraints noticeable only when we must use them in a foreign language. Although seemingly simple in terms of content, form and context of ordinary life when they are employed, these utterances are very singular. They are ritually emitted in common situations to which they are prototypically associated.
La maladie comme métaphore. Autour de la somatisation du politique dans « 2084. La fin du monde » de Boualem Sansal
Authors: Rachwalska von Rejchwald Jolanta
Published: October 2019

The aim of this paper is to present the interrelationship between politics and the representation of the patient’s body (pathography) in the novel of the Algerian contemporary activist and writer Boualem Sansal. In his novel, 2084. La fin du monde, whose title refers directly to Orwell’s work, Sansal creates a vision of a world dominated by religious totalitarianism. The purpose of this paper is to show how the affected body of the main character (and its recovery) becomes both a metaphor of opposition to the totalitarian system and a central structural, semantic and rhythmic figure of the text.
De l'engagement intellectuel a la déchirure: Sartre et les autres…
Authors: Alves Ana Maria
Published: October 2019

Claiming responsibility is not exclusively ethical or moral, but also political and ideological. The topic of the writer’s responsibility is at the heart of the main debates in the period 1914-1945. The French Intelligentsia stated its stand on the effective and active engagement of the intellectuals under the circumstances of having taken part in history. Until the end of the 1920s, intellectual commitment was feeble. It was only after the end of the 1930s that the intellectual commitment was “theorized”, gradually taking off to culminate with Sartre after the Second World War – the great figure of the intellectual committed.
Genre et littérature au XVIIe siècle : « La Princesse de Clèves » et ses enjeux politiques
Authors: Zoberman Pierre
Published: October 2019

This article explores the political implications, both at the time and for present-day readers, of the way La Princesse de Clèves calls into question gender norms/roles. Analyzing plots and characters in Lafayette’s text and readers/critics’ reactions in various contexts, it foregrounds the unsettling potential of a text that paradoxically moved from the position of hapax-cum- media-sensation to that of a paradigm of the early-modern novel. By focusing on its continued efficacy in disturbing heteronormative stereotypes, it sheds light on the way literature from before the modern era can contribute to identifying and analyzing queerness and gender dissidence in past historical contexts.
S’engager par le rire. Autour de quelques textes mineurs d’Albert Cohen
Authors: Vicens-Pujol Carlota
Published: October 2019

Albert Cohen, a committed writer? It is difficult to answer this question, so much the writer is difficult to classify, as he refuses to belong to any aesthetic movement. But the Zionist cause and the love of the Jewish people have marked his life as a man and as a writer. We will try to specify what is the Cohenian commitment from the analysis of some minor texts, in particular Projections ou Après-minuit à Genève et Mort de Charlot. Albert Cohen chose an aesthetic that is that of laughter, derisory and grotesque to express a dull pain that only humor can translate.
Darwin’s Monsters: Evolution, Science, and the Gothic in Christian Alvart’s ”Pandorum”
Authors: Pisarska Katarzyna
Published: October 2019

This article analyses Gothic tropes in the science fiction film Pandorum (2009, dir. Christian Alvart), through the lens of such concepts as evolution and science, which are presented in the film as inherently monstrous. Key to the analysis is the notion of the return of the repressed (or abjected) past which invades the future, disrupting biological, social, and moral borders of the human. This Gothic return, facilitated by advanced science and technology, turns the future into a site of humanity’s confrontation with their animal instincts, highlighting the fragility of our civilisation and proving our subjection to evolutionary processes.

ANTECEDENTES ARQUITECTÓNICOS PATRIMONIALES DEL DEPARTAMENTO DEL ATLÁNTICO
Authors: López Martínez Jairo Enrique
Published: October 2019

El estudio del desarrollo de los pueblos, y el estado de conservación de su patrimonio constituye un tema de suma importancia, ya que ayuda a conocer, entre otras cosas, las formas de vida de un lugar y la identidad cultural de sus gentes en un momento específico. Se plantea el estudio de los antecedentes arquitectónicos patrimoniales en el departamento del Atlántico, en el caso concreto del patrimonio edificado, que permita dar a conocer no solo el grado de mantenimiento de las estructuras que forman parte de éste, sino explorar las diversas maneras de entender el entorno, con base en factores como su morfología y tipología. Algunos municipios en el Sur del departamento del Atlántico se han visto afectados a partir de la catástrofe natural ocurrida por la hora invernal en el año 2011, lo cual ha ocasionado un fuerte impacto no solo en el estado de las edificaciones, sino en el ámbito socio-económico, generando la desesperanza en una comunidad arraigada a un lugar, que comúnmente se organiza en torno a un espacio público flanqueado por una unidad religiosa y edificios administrativos, rodeados por numerosas viviendas, lo cual se podría traducir en una morfología urbana propia de una actividad programada y estandarizada de la colonización española. El estudio de los antecedentes arquitectónicos patrimoniales en el departamento del Atlántico es pensado con el ánimo, de que provean a las administraciones municipales, de una herramienta que sirva de apoyo para solicitar de acuerdo a las Normas y Criterios del Ministerio de Cultura, la asignación de recursos para los Programas de Restauración y el Mantenimiento de Monumentos Nacionales que lleva a cabo la Dirección de Patrimonio.
