Le ralliement du pasteur Eugène Bersier et de l’Étoile à l’Église réformée, en 1877. Analyse d’une polémique ecclésiologique
Authors: Perin Luc
Published: July 2021

En novembre 1874, avenue de la Grande Armée à Paris, le pasteur Eugène Bersier (1831-1889) inaugure un temple d’environ 1 500 places avec une liturgie innovante : une nouvelle Étoile est née. Dès janvier 1875, Bersier envoie sa lettre de démission à la chapelle Taitbout, quittant ainsi les Églises libres séparées de l’État. Mais ce n’est que deux ans plus tard, en avril 1877, que l’Église de l’Étoile et ses deux pasteurs sont rattachés à l’Église réformée de France concordataire. Bersier justifie alors son évolution en remettant en question le principe d’Église de professants et en acceptant avec réalisme le lien avec l’État. Ce qui ne manque pas de provoquer une vive polémique avec les Églises libres. Tout en exposant leurs arguments ecclésiologiques, Luc Perin cherche dans cet article à clarifier les étapes et les raisons de l’évolution ecclésiastique du fondateur de l’Étoile.
Narrowing down the number of potential plant-based probiotic candidates by successive in vitro, technological and in vivo assays
Authors: Puntillo M. , Spotti J. , Salminen S. , Vinderola G.
Published: July 2021

The interest on plant-based fermented food is in raise in Western countries. The aim of this study was to select interleukin (IL)-10 inducing strains for the development of potential probiotic plant-based fermented foods. Departing from a collection of 52 lactic acid bacteria (LAB) strains derived from plant material, in vitro co-culture with murine macrophages allowed us to narrow down the number of candidates to 21 strains able to induce IL-10 secretion. 14 of these strains were able to promote the production of tumour necrosis factor-α too. The capacity to induce IL-6 was used to further reduce the number of strains to 4, from which Lactiplantibacillus plantarum subsp. plantarum LpAv was selected to ferment oat and carrots. L. plantarum LpAv was able to ferment oat and carrots until reaching counts of ca. 108 and 109 cfu/ml. Fermented oat and carrots were orally administered to mice for 10 consecutive days and challenged with a single infective dose of Salmonella enterica serovar. Typhimurium. Counts of L. plantarum LpAv in fermented carrots were 9.23±0.05 cfu/ml and 9.27±0.01 cfu/ml, at day 1 and 10 of the feeding period. Fermented carrots were able to confer enhanced protection (80% of survival) against infection, when compared to control mice (less than 25% of survival). However, L. plantarum LpAv administered as pure culture was not able to confer protection against Salmonella infection. L. plantarum LpAv was selected among 52 plant-derived LAB and it was able to ferment oat and carrots, being only fermented carrots able to confer enhanced protection against Salmonella infection. A succession of in vitro to in vivo tests is proposed as a tool to narrow down the number of candidates when searching for potential novel probiotics from a collection of autochthonous strains.
Null controllability for a class of stochastic singular parabolic equations with the convection term
Authors: Yan Lin , Wu Bin
Published: July 2021

This paper concerns the null controllability for a class of stochastic singular parabolic equations with the convection term in one dimensional space. Due to the singularity, we first transfer to study an approximate nonsingular system. Next we establish a new Carleman estimate for the backward stochastic singular parabolic equation with convection term and then an observability inequality for the adjoint system of the approximate system. Based on this observability inequality and an approximate argument, we obtain the null controllability result.
Robust optimal asset-liability management with penalization on ambiguity
Authors: Yuan Yu , Mi Hui
Published: July 2021

In this paper, we study the robust optimal asset- problems for an ambiguity-averse investor, who does not have perfect information in the drift terms of the risky asset and liability processes. Two different kinds of objectives are considered: \begin{document}$ (i) $\end{document} Maximizing the minimal expected utility of the terminal wealth; \begin{document}$ (ii) $\end{document} Minimizing the maximal cumulative deviation. The ambiguity in both problems is described by a set of equivalent measures to the reference model. By the stochastic dynamic programming approach and Hamilton-Jacobi-Bellman (HJB) equation, we derive closed-form expressions for the value function and corresponding robust optimal investment strategy in each problem. Furthermore, some special cases are provided to investigate the effect of model uncertainty on the optimal investment strategy. Finally, the economic implication and parameter sensitivity are analyzed by some numerical examples. We also compare the robust optimal investment strategies in two different problems.
Europa en Castilla: obispos diplomáticos y arquitectura del tardogótico
Authors: Alonso Ruiz Begoña
Published: July 2021

La renovación del siglo XV castellano ha sido relacionada en diversas ocasiones con la labor de determinados prelados y sus misiones diplomáticas por Centroeuropa o Flandes, del mismo modo que la llegada del Renacimiento a Castilla aparece inexorablemente unida a otras figuras de diplomáticos en Italia. Nos ocupamos en estas páginas de varios obispos que visitaron centros artísticos europeos como diplomáticos, a la vez que desarrollaron una importante actividad como promotores artísticos. Nos interesa preguntarnos en este estado de la cuestión acerca de cómo pudo ayudar el viaje en sus encargos y cómo esos lenguajes de fuera pudieron –o no– reflejarse en sus promociones artísticas, especialmente en las arquitectónicas.
Los obispos napolitanos como patrocinadores de arte: de Anjou a Aragón
Authors: Bock Nicolas
Published: July 2021

Dentro de la nobleza napolitana, los Carafa fueron sin duda los más fieles y devotos a la Casa de Aragón. Desde 1458 hasta 1576, la familia Carafa ocupó el arzobispado napolitano casi sin interrupción. Su mecenazgo –la restauración del ábside y la cripta de la catedral alrededor de 1500, el Succorpo di San Gennaro–, se sitúa en una perspectiva del patronazgo episcopal napolitano a largo plazo. El objetivo es mostrar cómo la fábrica existente de la catedral determinó las acciones de cada patrocinador desde los tiempos angevinos.
Las yacentes episcopales como mecanismos de pronóstico escatológico. Contextos teológicos de los sepulcros de Juan de Aragón y Arnau Sescomes
Authors: Boto Varela Gerardo , Serrano Coll Marta
Published: July 2021

Este artículo razona cómo las esculturas yacentes ad similitudinem de las tumbas episcopales de los siglos XIII y XIV, además de excitar el recuerdo del difunto, visualizaban la condición perceptible que ofrecerían los prelados tras ser elegidos en el Juicio, alcanzar el Cielo y gozar de la visión beatífica. La polémica especulación de que el alma pudiera ver a Dios antes de la reintegración con su cuerpo no fue ajena a la sede de Tarragona en 1330-1350. Las sepulturas monumentales de los arzobispos Juan de Aragón y Arnau Sescomes, implicados en esa deliberación teológica, remiten al pasado tanto como al futuro, multidireccional y simultáneamente.
Dos conjuntos funerarios episcopales de la catedral de Pamplona en el siglo XIV: la capilla funeraria de Miguel Pérez de Legaria y el sepulcro de Miguel Sánchez de Asiáin
Authors: Fernández-Ladreda Aguadé Clara
Published: July 2021

Se analizan dos conjuntos funerarios episcopales del siglo XIV pertenecientes a la catedral de Pamplona. En el caso del primero, el del obispo Miguel Pérez de Legaria (1287-1304), compuesto por tumba y capilla funeraria –ambas desaparecidas–, se destaca que se trataría de la más antigua capilla funeraria privativa construida exprofeso en Navarra, y se plantean hipótesis sobre su estructura, localización y cronología. En el del segundo, el de Miguel Sánchez de Asiáin (1357-1364), integrado solo por el sepulcro, se llama la atención sobre la existencia de más vínculos con Italia de los señalados hasta el momento, el empleo del Speculum Humanae Salvationis como fuente textual del conjunto del programa figurativo y la excepcionalidad de la iconografía de la Doble intercesión en el contexto europeo e hispano, para concluir con el planteamiento de la posible identidad del promotor.
Iste liber est de Fernandus episcopus cordubensis. Libros y librerías episcopales peninsulares en el otoño de la Edad Media (siglos XIII-XV)
Authors: Iglesias-Fonseca J. Antoni
Published: July 2021

La biblioteca episcopal, en la doble acepción de biblioteca particular de un obispo y de biblioteca institucional, está bien testimoniada para el período bajomedieval (ss. XIII-XV). A partir de documentación diversa (cancillería, eclesiástica, notarial, etc.) y de códices conservados (algunos con exlibris, notas de posesión, emblemas heráldicos y otros indicios), es posible hacer una aproximación a los libros y librerías episcopales peninsulares de ese periodo. Su estudio, en general, se había limitado a la edición y análisis de los documentos que las recogían. En las últimas décadas, en cambio, han proliferado los dedicados al estudio del mecenazgo de un obispo concreto o de un conjunto más amplio (por ejemplo, el patrocinio de obispos catalanes o aragoneses en época bajomedieval). También ha recibido una atención especial el Pontifical, el “libro del obispo”, una tipología libraria específica y muy relevante por su factura lujosa.
La promoción artística del arzobispo compostelano don Lope de Mendoza: devoción, culto y estrategia en el ámbito atlántico
Authors: Cendón Fernández Marta , Chao Castro David
Published: July 2021

En el presente trabajo se estudia la promoción artística del arzobispo don Lope de Mendoza (1400-1445) en dos de las villas costeras más destacadas de la Tierra de Santiago: Muros y Noia. Se ha dejado de lado el patronazgo episcopal en la propia Compostela y Padrón por haber sido tratado por la historiografía, optando por abordar conjuntos monumentales que sirvieron al prelado como refrendo del apoyo prestado a los florecientes puertos arzobispales y nuevos linajes urbanos que ocupaban sus oficios concejiles, así como su amparo y cuidado de los peregrinos al sepulcro apostólico. Pero ante todo el análisis planteado desde esta óptica hacia ejemplos tan destacados como Santa María do Campo de Muros o San Martín de Noia nos permite obtener esa pretendida imagen del poder, prestigio y sentido piadoso del que pasa por ser uno de los mitrados más destacados de la Baja Edad Media compostelana e hispana.
Lo que antecede al maduro y oportuno patrocinio artístico del obispo Luis de Acuña (circa 1426-1495)
Authors: Cosmen Alonso María Concepción
Published: July 2021

La figura de Luis de Acuña y Osorio ha sido muy bien valorada, desde finales del siglo XV, por su condición de hombre culto, generoso y gran promotor. Pero estos adjetivos se aplicaban, fundamentalmente, a la última etapa de su trayectoria pública, que transcurrió como obispo de la sede burgalesa. Con este estudio se ha intentado averiguar si el prelado cimentó su posterior fama en su juventud y, sobre todo, durante el desempeño de su cargo en la cátedra de Segovia, el primer puesto relevante de su carrera eclesiástica.
Colonial-Vernacular Houses of Java, Malaya, and Singapore in the Nineteenth and Early Twentieth Centuries
Authors: Tajudeen Imran bin
Published: July 2021

This study reviews the spatial and formal translations across indigenous vernacular and European colonial architecture in the formation and development of two nineteenth-century colonial-era house forms: first, the Compound House as it was called in building drawings, and the equivalent single story, raised-floor form, the Rumah Limas, in British Malaya (today’s Peninsular Malaysia and Singapore); and second, the Indies-style town residence (Indische woonhuis), which is related to, but distinguishable from, the larger, eighteenth-century country house (Indische landhuis) in Java. The discussion moves beyond the typical focus on climatic adaptation and style to consider a number of striking parallels in the interior layout and formal composition of these colonial-vernacular house forms with Malay, Sundanese (West Java) and Javanese customary house traditions, including Javanese urban dwellings. In addition, two key spatial-formal translations and their related architectural nomenclature are reviewed: the neo-Palladian portico as Malay anjung/surong, and the Javanese pringgitan or transition terrace as voorgalerij. Through these considerations, different narratives emerge that supplement or problematize the focus on Europeans in the colonies in existing studies.
Locating the Domestic in Vann Molyvann’s National Sports Complex
Authors: Nelson Roger
Published: July 2021

Cet article aborde la question de la construction et de l’interprétation de l’architecture post-indépendance au Cambodge en s’appuyant sur l’exemple du stade national à Phnom Penh, conçu par Vann Molyvann et achevé en 1964. Jusqu’ici, la plupart des études sur le stade, et sur l’œuvre de Molyvann et l’architecture moderne cambodgienne plus généralement, ont souligné la présence de références stylistiques angkoriennes. D’un point de vue historiographique, cette insistance sur les liens avec les temples d’Angkor a pour effet la construction d'un discours à la fois téléologique et limité par le concept de nation. La contre-lecture présentée ici rapproche le stade plutôt de l’architecture domestique, ce qui permet de mettre davantage l’accent sur des formes architecturales contemporaines et des intersections régionales plus larges. Cet article propose trois approches différentes mais croisées, correspondant à trois notions du domestique. La première, s’appuyant sur des archives conservées au Cambodge et aux États-Unis, considère le contexte historique de la construction du bâtiment, offrant le stade comme emblème de la politique cambodgienne de non-alignement pendant la guerre froide, sous le règne du prince Sihanouk. La deuxième est iconographique : elle examine les références aux maisons en bois sur pilotis présentes au sein du stade, ainsi que la reprise, dans des maisons privées et de conception anonyme, de traits architecturaux caractéristiques des grands bâtiments publics. La troisième approche, spatiale et expérientielle, aborde la division interne des espaces du stade en zones à échelle réduite.
The Ottoman-Turkish House According to Architect Sedad Hakkı Eldem
Authors: Acciai Serena
Published: July 2021

This is the first study that takes into consideration part of the vast and unexplored correspondence of Turkish architect Sedad Hakkı Eldem. In particular, it analyzes the portion of the accessible letters of Eldem which focus on the geographical extension of the Ottoman-Turkish house. The rediscovery of vernacular architecture had an essential role during the formation of national identity in Turkey, and this phenomenon was not an isolated case in the panorama of modern architecture in the Mediterranean. Sedad Hakkı Eldem’s letters show that he had established a network of correspondents from all over the former Ottoman world, who were investigating the range and breadth of the so-called Ottoman-Turkish House. These letters take their reader on a path through the experiences of a lifetime, highlighting Eldem’s professional relationships and theories and his deepest architectural passions, and offering a more personal point of view than the conventional iconographic portrayal of the “State Architect”.
Wikipédia à tous les étages. Usages de l’encyclopédie pour l’enseignement en géographie
Authors: Commenges Hadrien
Published: July 2021

Depuis sa naissance, Wikipédia a fait l’objet de nombreux travaux dans des disciplines variées : informatique, linguistique, géographie, science politique, etc. L’usage de Wikipédia comme objet de recherche n’a jamais posé problème, en revanche, l’usage de Wikipédia pour l’enseignement, en particulier pour l’enseignement universitaire, a toujours posé problème. Une majorité d’enseignants sont méfiants vis-à-vis de l’encyclopédie et recommandent explicitement aux étudiants de ne pas l’utiliser. Malgré ces recommandations, les élèves et les étudiants utilisent massivement Wikipédia pour la recherche d’information, tout en considérant, après leurs enseignants, qu’il s’agit d’une source illégitime. Ainsi, l’encyclopédie dispose d’un statut ambivalent, elle est à la fois utilisée et méprisée par les étudiants et les enseignants alors que très peu d’entre eux sont contributeurs. Wikipédia reste très peu intégrée aux enseignements universitaires alors qu’elle présente des avantages certains. Dans ce texte je propose un retour d’expérience issu de trois modules donnés dans l’UFR de géographie de l’Université Paris 1 - Panthéon Sorbonne. À partir de ces expériences je mets en avant l’intérêt que représente l’usage de Wikipédia pour l’enseignement universitaire, en SHS et en géographie en particulier.
Minage de cryptomonnaies à Irkoutsk
Authors: Estecahandy Hugo
Published: July 2021

Depuis plusieurs années, le minage de cryptomonnaies se développe à une échelle industrielle dans l’oblast' d’Irkoutsk, en Sibérie orientale. Ce processus de création de certaines monnaies numériques, dont le bitcoin, nécessite une importante puissance de calcul informatique et donc, des ressources particulières. En plus de concentrer de grandes quantités de ces ressources à un prix attractif et un climat adapté, Irkoutsk dispose de certaines caractéristiques sociopolitiques qui ont facilité l’émergence de l’activité. De nouvelles dynamiques apparaissent dans la région grâce au minage et, bien qu’elles restent encore limitées, font émerger le territoire marginalisé d’Irkoutsk comme un espace propice à certaines activités numériques.

Different components of the immune response show large variability between individuals, but they also vary within the same individual because of host and environmental factors. In this study, we report an extensive analysis of the immune characteristics of 56 individuals over four timepoints in 1 single year as part of the Human Functional Genomics Project. We characterized 102 cell subsets using flow cytometry; quantified production of eight cytokines and two chemokines in response to 20 metabolic, bacterial, fungal, and viral stimuli; and measured circulating markers of inflammation. Taking advantage of the longitudinal sampling, both seasonal and nonseasonal sources of variability were studied. The circulating markers of inflammation IL-18, IL-18 binding protein, and resistin displayed clear seasonal variability, whereas the strongest effect was observed for α-1 antitrypsin. Cytokine production capacity also showed strong seasonal changes, especially after stimulation with the influenza virus, Borrelia burgdorferi, and Escherichia coli. Furthermore, we observed moderate seasonality effects on immune cell counts, especially in several CD4+/CD8+ T cell subpopulations. Age of the volunteers was an important factor influencing IFN-γ and IL-22 production, which matched the strong impact of age on several T cell subsets. Finally, on average, genetics accounted for almost 50% of the interindividual variance not already explained by age, sex, and body mass index, although this varies strongly for different parameters. In conclusion, seasonality is an important environmental factor that influences immune responses, in addition to specific genetic and nongenetic host factors, and this may well explain the seasonal variation in the incidence and severity of immune-mediated diseases.

Authors: Chaudhuri Arunima , Paul Suhrita , Mondal Tanushree , Goswami Ayan
Published: July 2021

Background:

Continuing Medical education during the COVID-19 Pandemic has been a great challenge to Medical educators, especially teaching clinical skills online.

Aims:

The study aims too study the efficacy of teaching ECG in online mode to first MBBS students in the Department of Physiology.

Materials and Methods:

There are 200 students in the first MBBS batch at Burdwan Medical College. Our method of teaching was flipped classroom-assisted self-directed learning. For teaching ECG to our students we had first arranged for presession MCQ to assess the initial level of knowledge. We had then provided the students with PowerPoint presentations with voice narrations for their self-study, following which the students were divided into batches of twenty and each batch had a team leader and a facilitator. These small batches were shown videos of instruments, methods of recording ECG, normal and abnormal ECG along with explanations in multiple sessions (10). Doubt clearing sessions were arranged for each batch and these sessions were brainstorming. The students were assessed with MCQs (10 marks each Session), oral questions, short answer type questions, spots, and problem-based questions. We also took a feedback survey from the students and provided the students with feedback regarding their performance.

Results:

MCQ assessments of students in Pre and Posttest session on ECG teaching classes were 50.39 ± 19.41 vs. 65.25 ± 9.14; P ≤ 0.001**. Students performed significantly better in MCQ assessments of students on Normal parameters of ECG assessment as compared to Abnormal ECG parameters: 67.25 ± 10.98 vs. 63.157 ± 7.399; P = 0.000424**. Results of Written Examination and Viva Examination of students in ECG classes were 64.844 ± 9.923 vs. 71.89 ± 10.49; P ≤ 0.001**.

Conclusions:

The online method of teaching ECG was a success in the institution as observed in this study as observed in the assessment. Students performed better in viva in online exam for ECG and students were satisfied with online delivery.
Periodic Jacobi operators with complex coefficients
Authors: Papanicolaou Vassilis G.
Published: July 2021

We present certain results on the direct and inverse spectral theory of the Jacobi operator with complex periodic coefficients. For instance, we show that any

N

-th degree polynomial whose leading coefficient is

(-1)^N

is the Hill discriminant of finitely many discrete

N

-periodic Schrödinger operators (Theorem 1). Also, in the case where the spectrum is a closed interval we prove a result (Theorem 2) which is the analog of Borg's Theorem for the non-self-adjoint Jacobi case.

Effects of Dietary Mannan Oligosaccharide on Growth Performance, Feed Utilization, Body Composition and Haematological Parameters in Asian Catfish (Clarias batrachus) Juveniles
Authors: Akter Mst. Nahid , Zahan Khurshid , Zafar Md. Abu , Khatun Najida , Rana Md. Sohel , Mursalin Md. Imamul
Published: July 2021

The influence of dietary supplementation of mannan oligosaccharide (MOS) on growth performance, feed utilization, body composition and haematological parameters were evaluated in Asian catfish (Clarias batrachus) juveniles. Triplicate groups of juveniles Asian catfish (21.23 ± 1.01 g) were fed twice per day at 3 % of body weight for 12 weeks, with 0 (control), 0.2, 0.4 or 0.6% MOS diets. Compared to control, those fed with MOS supplemented diets had significantly improved (P<0.05) specific growth rates, protein efficiency ratio and survival rate. Significantly lower hepatosomatic index was noted in 0.2% and 0.4% MOS diets compared to those fish fed control. Similarly, intraperitoneal fat was significantly lowest in those fish fed with 0.4% diet over the control group. The highest protein content was (81.86±0.36) in fish fed with 0.4% MOS diet, whereas ash content was highest (7.33±1.23) in fish group fed with 0.6% MOS. Significantly decreased erythrocyte sedimentation rate and increased packed cell volume were observed when the fish fed with 0.4% and 0.6% MOS diets compared to the remaining treatments. MOS supplemented diets showed significant influence on the white blood cell count compared to the control. Thus, 0.4% MOS is sufficient to improve growth and haematological parameters in Asian catfish.
Musicology went Pop: Raziskovanje globalnih glasbenih tokov skozi prizmo nacionalnih šol in drugih znanstvenih konvencij

Prav tako kot v ZDA in Veliki Britaniji je bil tudi v Zvezni republiki Nemčiji  eden od prvih pristopov k raziskovanju popularne glasbe sociološki. Nadaljnji impulzi so prihajali s področja glasbene pedagogike. V okviru nemške znanstvene  organizacije z imenom Arbeitskreis Studium Populärer Musik e.V. se je akademski diskurz o popularni glasbi sprva naslonil na sistematično muzikologijo, nato pa je pričel upoštevati tudi izsledke sorodnih disciplin, med  njimi  sociologije,  etnologije,  antropologije, »cultural studies« in »gender studies«. S tem se je odprl nov zorni kot približevanja glasbenim fenomenom, ki skuša ujeti v smiselne aksiome predvsem kompleksnost in polivalentnost glasbenih procesov. Na osnovi teh izkušenj prestavlja za avtorico osnovni predmet muzikološkega raziskovanja glasbeno življenje kot živ in nenehno se spreminjajoč organizem. Zavzema se za celostni pristop k raziskovalni materiji, metodološki pluralizem, interdisciplinarnost raziskovanja, iskanje dialoga z drugimi znanstvenimi panogami ter vodenje konstruktivnega diskurza med različnimi pogledi, ·šolami in teoretskimi pozicijami.

Published: July 2021

Owing to the unprecedented advancements in digital technologies adopted for use in marketing tourism, their use in tourism is expected only to gain momentum. The purpose of this paper is to systematically review literature published in tourism-related journals on digital marketing tools in tourism from 2016-2020, and to discuss future trends. The analysis reveals that the increased adoption of digital marketing tools has disrupted the status quo of the tourism industry. Findings also highlight a growing and broad digital marketing tools terrain that is thematically diverse. Tourism marketers have to ensure that they understand the trends in the digital marketing domain and be able to adapt to the changes in order to remain competitive. Based on literature synthesis, the study provides insights into practical managerial implications and provides the groundwork for future studies.

Authors: Tung Le Thanh
Published: July 2021

The study aimed to analyse the general impact of the COVID-19 pandemic on global tourism. Obviously, the world tourism industry has been received unprecedented damages never ever seen before. The thematic analysis approach, comparative research method and descriptive statistical analysis are used to investigate the effects of this pandemic. In general, the empirical analysis results show having a high sensitivity to diseases, global tourism is considered as one of the hardest economic sectors hit by the COVID-19 pandemic outbreak. First, these huge losses in revenue are still ongoing because the pandemic is fastly spreading worldwide. The hurts of global tourism are serious and can put the whole travel and tourism industry in long-term disruptions. Second, although global tourism has proven strong resilience in response to other previous crises, the results suggest that the negative impacts of this pandemic will longer-lasting expand on would tourism industry compared to others. Third, the analysis result highlights that the countries need robust and urgent solutions for global tourism to reduce the huge losses received from this pandemic. However, this pandemic can have potential long-term changes in customer behaviors and the supply chain in global tourism to help efficiently combat risks from epidemics in the future. Finally, the study results suggest some implications to policymakers and business people in the reconstruction of the tourism industry in countries in the coming time.
Examining the Challenges and Opportunities of Multi-Level Marketing for Resort Hotels: A Delphi Study
Authors: Sobaih Abu Elnasr E. , Ghannam Sally , Aliedan Meqbel M.
Published: July 2021

Environmental changes push hotels to seek additional and innovative channels to market their products/services while maintaining a high occupancy rate and revenues with lower marketing costs. Building on network theory, this research investigates the extent to which multi-level marketing (MLM) can be adopted as an appropriate and innovative marketing channel for resort hotels. A Delphi study was undertaken with hotel and MLM experts to explore their perceptions about the opportunities and challenges of MLM for resort hotels. The results showed that MLM could appropriately be developed as an innovative marketing channel for resort hotels if challenges are fully addressed and controlled by hoteliers. Two models are proposed for proper implementation of MLM for resort hotels. The first model uses current customer/s as a marketer/s. This includes sharing resort experience using social media posts. The second model uses MLM companies as a channel for marketing hotel products/services to new customers. Several theoretical and practical implications of the study were discussed.

Under the impact of covid-19, the global and domestic manufacturing supply chains, almost suffered from the serious interruption crisis of manpower flow, logistics, information flow and capital flow. The risk of supply chain disruption has become the primary risk of the supply chain. However, some risk inducement of supply chain interruption is complex and diverse, so it is very difficult to grasp and screen the risk data needed for research from the supply chain operation data. To improve the robustness of supply chain for boosting the domestic and international circulation of China's manufacturing, in this paper, according to the characteristics of China's manufacturing supply chain and its risk incentives, the data needed for risk prediction modeling has been sorted out through questionnaire survey, and a regression model of risk prediction for manufacturing supply chain by using empirical method would be put forward. Then, C4.5 decision tree method is used to train and evaluation the risk prediction model. The conclusion shows that the customer satisfaction has great diagnostic value for risk, and the model has a strong sensitivity to market information risk and market order risk. The conclusion is more consistent with general cognition, and the model fits well, indicating that the model proposed in this paper has a certain theoretical significance, and its practical application value is worthy of further testing.

Giriş: Emzirme, bir bebeği beslemek için en güvenli ve sağlıklı yöntemdir. Annenin ve bebeğinin sağlık sonuçlarının iyileşmesine katkıda bulunur. Amaç: Bu çalışmada doğum sonu dönemde annelerin emzirme öz-yeterlilik algıları ile emzirme başarıları arasındaki ilişkiyi incelemek amaçlanmıştır. Yöntem: Tanımlayıcı tasarımdaki bu araştırmanın örneklemini, Akdeniz Bölgesindeki bir üniversite hastanesinin Kadın Doğum servisinde yatan, sağlıklı yeni doğum yapmış 102 anne oluşturmuştur. Veri toplama aracı olarak; tanımlayıcı veri formu, Emzirme Öz-yeterlilik Ölçeği-kısa şekli, LATCH Emzirme Değerlendirme Aracı kullanılmıştır. Emzirme öz-yeterliliği verileri yüz yüze görüşme yöntemi ile toplanmıştır. Annelerin emzirme başarıları gözlem yöntemi ile değerlendirilmiştir. Bulgular: Araştırma kapsamındaki annelerin %47.1’inin 26-33 yaşında, %38.2’si ilkokul mezunu, %68.6’sı sezaryen ile doğum yapmış ve %30.4’ünün ilk doğumu olduğu tespit edilmiştir. Annelerin emzirme öz yeterliği puan ortalaması 57.30 ± 10.46 ve emzirme başarıları puan ortalaması 8.38 ± 1.53 bulunmuştur. Annelerin emzirme öz yeterliliği ve emzirme başarıları arasında istatistiksel olarak anlamlı bir ilişki olmadığı saptanmıştır (p = .157, r = .14). Annelerin çocuk sayısı ile Emzirme Öz Yeterlilik Ölçeği ve LATCH Emzirme Değerlendirme Aracı puanları arasında anlamlı bir ilişki bulunmuştur (p < .05). Çocuk sayısı arttıkça annelerin emzirme öz yeterliliği ve emzirme başarısının arttığı belirlenmiştir. Sonuç: Yeni doğum yapmış annelerin emzirme döneminde sağlık profesyonelleri ve aile yakınları tarafından desteklenmesinin annelerin emzirme başarılarını ve emzirme öz yeterlilikleri artacağı düşünülmektedir.

Tunnel Field Effect Transistors (TFET) have
demonstrated to have likely applications in the
cutting-edge low force and super low force
semiconductors to substitute the conventional
FETs. TFET will be able to provide steep
inverse subthreshold swing slope also
maintaining a low leakage current, making it
an essential structure for limiting the power
consumption in Metal Oxide Semiconductor
FETs.In this paper, we are simulating different
structures of TFET by varying source material
to boost the ON current of the device. The
different models are designed and simulated
using Silvaco TCAD simulator and transfer
characteristics are studied.
Advancements in Interventional Techniques of Percutaneous Transluminal Coronary Angioplasty (PTCA) in Acute Myocardial Infraction
Authors: Joy R. Adlin Pon
Published: July 2021

Andreas Gruentzig is the father of interventional cardiology performed the first PTCA procedure in Zurich, Switzerland (1977). Later, the developments of angioplasty were done by interventional radiologist Charles Dotter. Percutaneous Transluminal Coronary Angioplasty (PTCA) is a primary procedure used in the field of interventional cardiology to treat blocked or stenosed coronary arteries. The blockages occur because of the lipid –rich plaque within the arteries causing diminished blood flow to the myocardium. In acute myocardial infarction, there is plaque rupture with platelet aggregation, and acute thrombus formation, which results in a sudden occlusion of coronary artery. The patient present with acute chest heaviness, diaphoresis, and nausea, urgent PTCA is required to save the life of the patient in order to limit the myocardial damage.

Published: July 2021

Osmanlı Devleti’nin doğu sınırında izlediği idari örgütlenme merkeze yakın eyalet ve sancaklardaki yapılanmadan hayli farklıydı. Bu örgütlenmeyi belirleyen ise kuşkusuz buradaki iki büyük rakip komşu devletin bu sınırlar üzerindeki hâkimiyet mücadelesiydi. Söz konusu bu özgün yapının mülki idari terminolojideki ismi hükûmet ve yurtluk-ocaklık sancaklardı. Bunlar arasında günümüze değin en az bilinenlerden biri Mihrani ocağıdır. Muhtar statülü idari birimler arasında yer alan Mihrani Ekrad sancağının diğer bir özelliği ise aşiret örgütlenmesine sahip olması ve aynı adı taşıyan aşiret mensuplarının üç farklı bölgede yerleşmiş olmasıydı. Araştırmada, Mihrani Ekrad sancağında uygulanan tımar sistemine değinilmiştir. Ayrıca, hanedanın dini bir imtiyaz olan seyyidlik iddiası ele alınmıştır.Bu çalışmada öncelikle idari bir statü olan Mihrani ocağı, akabinde ise üç farklı mıntıkada meskûn aşiretin başta kronikler olmak üzere, seyahatnameler, araştırma eserler ve özellikle Osmanlı arşivine yansımış görünümü tasvir edilmeye çalışılacaktır. Bu çalışmayı özgün kılan husus, konunun daha önce hiçbir yerde ele alınmamış olmasıdır. Haliyle bu araştırma Mihraniler’e dair kaleme alınan ilk özgün çalışmadır.

La estética de la música y la belleza de la trova, se vio reflejada en la actividad de disertación académico-musical que se realizó en el Doctorado en Investigación en Educación, el sábado 1 de mayo del año 2021; con el Cantor y Trovador Otto Mora, quien inició expresando que el arte integra la música como una manifestación que proporciona una experiencia estética que motiva la percepción individual, la creatividad y estimula los sentimientos, los pensamientos y las ideas. Gracias a los aspectos personales de tipo emocional, lo cual permite descubrir la estética de la obra. Entre los elementos estéticos musicales están la armonía y la emotividad, que están inmersos en la estética y las relaciones entre complejidad y estética, que conocen de diversidad, de transformaciones, de transiciones, de emergencia, de impredecibilidad y de autoorganización. Y el pensamiento sistémico, que nos plantea el concepto de propiedades emergentes de los sistemas como el calor, la sinergia y la buena vibra; aseguró Mora que la música es una propiedad emergente del sistema que la produce.
Avaliação dos saberes na mediação online na educação superior semipresencial
Authors: De Miranda Naíola Paiva
Published: July 2021

A educação superior a distância no Brasil tem sido desafiada a integrar esse novo processo educativo com um corpo de profissionais da educação, entre eles o tutor presencial e o tutor a distância. Neste trabalho se discute sobre o tutor a distância, objetiva-se avaliar os saberes da mediação online do tutor a distância na educação superior semipresencial. A relevância deste estudo se reporta a necessidade que se tem em avaliar o trabalho do tutor durante e após a sua atuação e no que precisa melhorar. O tutor a distância com uso de ferramentas e artefatos realiza a mediação online da aprendizagem do aluno através do ambiente virtual de aprendizagem. Indaga-se, portanto que saberes o tutor a distância precisa se apropriar para realizar esse trabalho educativo na educação semipresencial? A pesquisa com natureza transversal e descritiva, os dados tiveram uma abordagem quantitativa. Desenvolvida a partir do referencial teórico em relação aos saberes atitudinais, conceituais e procedimentais (COLL,1998). Observou-se que a pesquisa apresentou no modelo final fornecido pela regressão múltipla e comparando-se os coeficientes padronizados β, na dimensão conceitual maior peso na composição da nota da escala de avaliação (β = 0,529), entendeu-se que os saberes conceituais estão bem representados  na avaliação dos alunos para com os tutores. Quanto ao saber atitudinal atingiu a um patamar de (β = 0,319), sinalizou a uma linha mediana entre os saberes, o que se concebe que o grau de motivação se encontra acima da média em relação aos resultados dos saberes conceituais. O saber procedimental apresentou-se abaixo da média que o saber conceitual, a um nível de (β=0,233). Os resultados apontaram que   este nível revela que apesar de o tutor receber tudo pronto, as metodologias e estratégias didáticas devem ser mais intensificadas, pois precisa mediar no que concerne a linguagem adequada, presença social online mais intensificada no ambiente virtual de aprendizagem, atividades de aprendizagens  direcionadas e atividades de avaliação diagnósticas, formativas e contínuas que regulem a aprendizagem do aluno.
