Chemical Abundance Scaling Relations for Multiple Elements in z ≃ 2–3 Star-forming Galaxies
Authors: Strom Allison L. , Rudie Gwen C. , Steidel Charles C. , Trainor Ryan F.
Published: January 2022

The chemical abundance patterns of gas and stars in galaxies are powerful probes of galaxies’ star formation histories and the astrophysics of galaxy assembly but are challenging to measure with confidence in distant galaxies. In this paper, we report the first measurements of the correlation between stellar mass (M
*) and multiple tracers of chemical enrichment (including O, N, and Fe) in individual z ∼ 2–3 galaxies, using a sample of 195 star-forming galaxies from the Keck Baryonic Structure Survey. The galaxies’ chemical abundances are inferred using photoionization models capable of reconciling high-redshift galaxies’ observed extreme rest-UV and rest-optical spectroscopic properties. We find that the M
*–O/H relation for our sample is relatively shallow, with moderately large scatter, and is offset ∼0.35 dex higher than the corresponding M
*–Fe/H relation. The two relations have very similar slopes, indicating a high level of α-enhancement—O/Fe ≈ 2.2 × (O/Fe)⊙—across two decades in M
*. The M
*–N/H relation has the steepest slope and largest intrinsic scatter, which likely results from the fact that many z ∼ 2 galaxies are observed near or past the transition from “primary” to “secondary” N production, and may reflect uncertainties in the astrophysical origin of N. Together, these results suggest that z ∼ 2 galaxies are old enough to have seen substantial enrichment from intermediate-mass stars, but are still young enough that Type Ia supernovae have not had time to contribute significantly to their enrichment.

Blazars show extreme observational properties that are due to the beaming effect with the jet being close to the line of sight. It was found that the observed luminosity is anticorrelated with the synchrotron peak frequency but the debeamed luminosity and the frequency is positively correlated. In this work, we revisit this correlation for a large sample of 255 blazars from the fourth Fermi catalog with available Doppler factors. Our analysis comes to the following conclusions. (1) The observed radio, X-ray, γ-ray, and synchrotron peak luminosity are all anticorrelated with the peak frequency, but the debeamed luminosity is positively correlated with the debeamed peak frequency. The anticorrelation is due to a selection effect or a beaming effect. (2) The Compton dominance parameter is correlated with both the bolometric luminosity and Doppler factor, implying that the more highly Compton-dominated sources are more luminous. (3) The bolometric luminosity can be represented by the γ-ray luminosity for Fermi blazars.

Published: January 2022

We report the results of the trajectory-based simulation of far-infrared collision-induced absorption (CIA) due to CH4–N2 pairs at temperatures between 70 and 400 K. Our analysis utilizes recently calculated high-level potential energy and induced dipole surfaces. Treating collision partners as rigid rotors, the time evolution of interaction-induced dipole is accumulated over a vast ensemble of classical trajectories and subsequently transformed into a CIA spectrum via Fourier transform. In our calculations, both bound and unbound states are properly accounted for, and the rigorous theory of lower-order spectral moments is addressed to check the accuracy of simulated profiles. Classically derived trajectory-based profiles are subject to two approximate desymmetrization procedures so that resulting profiles conform to the quantum principle of detailed balance. The simulated profiles are compared to laboratory measurements and employed for modeling Titan’s spectra in the 50–500 cm−1 range. Based on the desymmetrized simulated profiles, a new semiempirical model for CH4–N2 CIA is proposed for modeling Titan’s infrared spectra. Synthetic spectra derived using this model yield an excellent agreement with the data recorded by the Composite Infrared Spectrometer aboard the Cassini spacecraft at low and high emission angles.

Published: January 2022

BACKGROUND: Yoghurt is a milk fermentation product that is one of the highly nutritious food materials involving bacteria. Yoghurt is formed from lactic acid bacteria (LAB), namely, Lactobacillus bulgaricus, Lactobacillus acidophilus and Streptococcus thermophilus. The bacteria are beneficial for health because it creates a balance of the intestinal microflora. Moreover, yoghurt has a distinctive freshness, aroma and taste, namely, sour. In the yoghurt fermentation process, LAB needed a substrate for their growth. The content of natural sugar in milk is minimal; therefore, jelly needs to be added, which the microorganism can directly use for its growth.
AIM: This study aims to determine the effect of adding jelly with various concentrations and storage time on the number of LAB in processed yoghurt products.
METHODS: This research used the measurement method of total LAB with plate count method using completely randomized design factorial pattern 1 × 3 with three repetitions. The factor I is the jelly concentration (0.5%, 0.75% and 1%) and factor II is storage time (7 days, 14 days, 21 days at a temperature of 2–8°C) with data processing using statistical tests, namely, two-way analysis of variance test followed by Duncan’s Multiple Range Test.
RESULTS: The results showed significant differences in the storage time of 7 days, 14 days, and 21 days on agar with concentrations of 0.5%, 0.75%, and 1%. The highest LAB amount was on the 7th day with a concentration of 1% with 2.51 × 109. While on the 21st day, with a concentration of 1%, it had the lowest LAB amount of 3.2 × 108. However, the amount of LAB was still above the Indonesian National Standard, namely >107 CFU/mL.
CONCLUSION: This study concluded that the highest number of LAB was found in the addition of 1% jelly with a storage time of 7 days with a total LAB yield of 2.51 × 109 CFU/mL. Storage time on day 7, day 14 and day 21 and jelly concentrations of 0.5%, 0.75%, and 1% added to processed yoghurt had a significant effect (p < 0.05) on the total number of LAB (p < 0.05) LAB).

Published: January 2022

BACKGROUND: Thrombolytic treatment is the main treatment of acute ischemic stroke. Thailand started thrombolytic treatment in 2008 only at university hospitals in Bangkok and gradually increased services in large provincial hospitals until widespread in 2014. However, no studies regard the services in stroke management in Thailand.
AIM: This study aims to present data: incidence, rate of thrombolytic treatment, mortality rate of acute stroke in Thailand for 13 years
METHODS: A study from the National Health Security Office's database between 2009 and 2021 was reported using percentage statistics, and the number of patients per 100,000 population.
RESULTS: The overall incidence of acute stroke patients aged 15 years and over was 172.33- 328.00 per 100,000 population. The incidence of acute ischemic stroke patients aged 15 years and over was 90.37-222.73 per 100,000 population. The incidence of non-traumatic intracerebral hemorrhage patients aged 15 years and over was 55.77-87.63 per 100,000 population. Rate of acute ischemic stroke patients who treated with thrombolytic treatment was 0.18-8.04%. Mortality rate of acute stroke patients was 10.24-14.77%. Mortality rate of acute ischemic stroke patients who treated with thrombolytic treatment was 3.97-10.53%.
CONCLUSIONS: Stroke incidence tends to increase over 13 years. Acute ischemic stroke patients receiving thrombolytic treatment tends to increase in number. The mortality rate in patients with acute stroke tends to decline. Especially in patients with acute ischemic stroke, the mortality rate was greatly reduced.

Published: January 2022

BACKGROUND: Pregnancy period is a crucial period for the maternal and infant health. Unfortunately, there are still many pregnant women having low knowledge, attitude, and practice (KAP). Meanwhile, the advanced technology and the occurrence of pandemic should have created change toward the method to provide education.

AIM: This research aims to compare the KAP of the pregnant women provided by an application with those provided with a module with pictures.

METHODS: This research was conducted in Deli Serdang Regency, North Sumatera Province. There were two groups of pregnant women, each of which consists of 32 people chosen from the pregnant women registered in two Public Health Centers. One group used the application and the other used the module with pictures. After 3 months, the KAP of those two groups was measured in accordance with the content of the module.

RESULTS: Those two groups had the profile of the same age and education, but their occupation was different, where the application users were mostly housewives, while the most of the module users were self-employed. The pregnant women using the application had a higher KAP than the pregnant women using the module with pictures.

CONCLUSION: The use of the application and the module with pictures is an important alternative to increase the KAP of the pregnant women.

Les lois de bioéthique ont pour fonction de fixer les limites de la condition humaine. Le débat qui entoure actuellement leur révision semble toutefois consacrer la confusion du droit avec l’éthique, au moment où il est nécessaire de tracer les limites que la technique ne doit pas franchir. Pour que ces limites soient effectives, deux conditions doivent être remplies. D’une part, elles doivent s’imposer aux personnes, c’est-à-dire restreindre la liberté d’action des personnages du théâtre juridique. D’autre part, les limites de la personne humaine face à l’évolution technologique doivent être pensées dans la longue durée. Comme dans toute pièce de théâtre dont l’histoire est cohérente, ce qu’il advient des personnages dans le futur n’est jamais séparable de leur passé. Le présent article a pour but d’éclairer le citoyen non juriste sur ces deux conditions inhérentes au fonctionnement du droit : d’abord en s’employant à déconstruire la prétention de l’éthique à édicter des règles juridiques ; ensuite en recherchant dans l’histoire du droit des éléments de réflexion sur la limite humaine qui soient utiles au débat citoyen.

Les évolutions sociétales et innovations technologiques ont conduit les pouvoirs publics à encourager la diffusion d’une culture de réflexion éthique à la génération en devenir. Par ailleurs, les États généraux de la bioéthique révèlent une grande réceptivité des jeunes gens au questionnement éthique. Pourtant, l’éducation des futurs citoyens à l’éthique peine à se développer. Afin de lui insuffler une réelle dynamique, il convient d’analyser ses aspects problématiques et d’envisager ses conditions d’existence, de développement et de pérennisation.

Les tests génétiques sont réalisés dans deux situations différentes, soit dans un cadre diagnostique pour rechercher l’étiologie et confirmer un diagnostic clinique ; soit, dans le cas où la mutation génétique a été identifiée au préalable dans la famille, à la demande de personnes à risque pour connaître leur statut génétique. Deux issues sont possibles avec une probabilité de 50 % dans le cas des maladies de transmission autosomique dominante : soit la personne à risque n’est pas porteuse de l’anomalie génétique et donc « sauvée » ; soit elle est porteuse et à risque de développer la maladie.

Les nanosciences proposent une véritable révolution des technologies, à la plus petite échelle de la matière, impliquant la physique, la chimie et la biologie et, même au-delà, tout ce qui concerne l’information et la cognition. L’avancée des nanosciences dans le domaine de la physique et de la chimie a permis de développer des méthodes et des objets uniques à ce jour. Il en est de même dans le domaine de la biologie. Au-delà des risques physiologiques, quels peuvent être les problèmes sociétaux suscités par ce bouleversement technologique ? Ils sont de trois ordres : liés à la limitation de la démocratie participative dans les choix des développements et des applications des résultats des nanosciences, au non-respect de la liberté individuelle et enfin au transhumanisme.

L’essor des neurosciences nous permet maintenant d’observer le cerveau sans l’endommager et d’y pratiquer certaines interventions. Avec ces progrès, des questions éthiques émergent, d’autant que le cerveau n’est pas un organe comme les autres : il est le support de notre personnalité. Les neurosciences mettent donc en jeu la conception que nous nous faisons de nous-mêmes comme personnes libres et responsables ainsi que le fonctionnement d’une institution comme la justice.

Les connaissances récemment acquises dans le domaine des neurosciences enrichissent notre compréhension du fonctionnement cérébral et ouvrent de nouvelles perspectives pour le traitement de maladies fréquentes et souvent lourdement invalidantes. Elles nous conduisent également à découvrir les mécanismes physiologiques sous-jacents à certains de nos comportements, de la prise alimentaire à la conduite sexuelle, de la perception visuelle à la capacité d’apprendre. Il en résulte une nouvelle conception de certains de nos mécanismes de pensée comme nos processus de prise de décision, ainsi qu’une capacité jusqu’alors inconnue d’agir sur certains de nos comportements sociaux. Il est dès lors nécessaire d’en examiner les tenants et aboutissants, en particulier lorsqu’il s’agit de contrôler le comportement de jeunes enfants, l’humeur d’une population, ou d’améliorer des performances intellectuelles. Dès lors, à une bioéthique spécifique de l’organe cérébral doit s’adjoindre un nouveau champ de réflexion : la neuroéthique.

À partir de quelques références psychanalytiques, l’auteur propose une lecture des transformations contemporaines de la représentation du corps induites par les pratiques biotechnologiques, et avance l’hypothèse d’un lien entre ces transformations et les mutations des systèmes symboliques de la modernité. Si le sujet est toujours sujet d’un langage, tout langage ne produit pas un effet de sujet. Le développement des langages sans sujet peut ainsi être un des facteurs explicatifs de la défaillance des processus anthropologiques traditionnels de symbolisation du corps. La possibilité même d’une éthique ne devient-elle pas dès lors problématique, s’il n’est d’éthique que du sujet ?
Les réponses des Scic aux enjeux agricoles émergeants : panorama et dynamiques

Published: January 2022

À travers une revue de presse et son analyse textuelle par le logiciel Iramuteq, cet article propose un panorama actualisé et problématisé des sociétés coopératives d’intérêt collectif (Scic) dans le secteur agricole. Les auteurs montrent comment, grâce au multisociétariat et à un ancrage territorial, les Scic répondent à des enjeux agricoles émergents. L’analyse menée sur la revue de presse permet notamment de mettre à jour quatre enjeux contemporains du secteur face auxquels la Scic semble porteuse d’innovations. Sont ainsi identifiés : la diversification du secteur agricole vers les énergies renouvelables ; la transition des filières vers l’agriculture biologique et les circuits courts de proximité ; l’affirmation de la gouvernance démocratique de collectifs de producteurs ; l’accès au foncier agricole ainsi que les stratégies relatives à l’installation des nouvelles générations et des néoruraux.
Quelles ressources et compétences pour réussir la stratégie de diversification d’une coopérative agricole ?
Authors: Valiorgue Bertrand , Bourlier-Bargues Émilie , Hollandts Xavier
Published: January 2022

Face aux difficultés récurrentes en matière de revenus, les coopératives agricoles françaises ont fait le pari de la diversification. Les facteurs de réussite de leurs stratégies en la matière sont peu étudiés, ce qui freine d’autant leur compréhension. En prenant appui sur la théorie des ressources, les auteurs dégagent quatre grandes stratégies de diversification des coopératives agricoles. Ils montrent que leur réussite dépend de la capacité de la coopérative mère à identifier les ressources et les compétences sur lesquelles elle peut s’appuyer pour bâtir une stratégie créatrice de valeur. Ils soulignent également les difficultés de pilotage que ces stratégies génèrent pour les dirigeants élus. Difficultés qui peuvent se traduire par une perte de contrôle et d’influence.

Les produits du terroir se construisent sur la base des ressources ancrées dans un territoire. La valorisation et la marchandisation de ces ressources dites « spécifiques ou territoriales » contribuent à dynamiser en interne l’économie locale, ce qui favorise la création de la valeur ajoutée territoriale. À travers une recherche qualitative et à caractère netnographique, les auteurs cherchent à rendre compte de la contribution de l’intentionnalité opératoire des coopératives à la valorisation du patrimoine d’Essaouira au Maroc, tout en étudiant l’impact de leurs activités sur l’économie locale. Les premiers résultats de cette recherche montrent l’importance de la mobilisation conjointe de l’ensemble des parties prenantes du territoire pour rendre possible tout projet territorial.
L’attention dans tous ses états en psychomotricité

Published: January 2022

Dans notre société moderne toujours en mouvement mais supportant mal le mouvement de l’enfant, la psychomotricité est souvent en première ligne des demandes de suivis, dans le cadre d’agitation et de troubles attentionnels. En partant de bilans pluridisciplinaires, le psychomotricien sera à même d’évoquer un diagnostic psychomoteur différentiel au plus proche de la clinique. Notre discipline a évolué, et nous voyons naître une approche plus neuropsychologique et cognitiviste, basée sur la théorie de Barkley, avec une prise en charge ciblée sur le contrôle de l’inhibition motrice et l’organisation des tâches. Pour ma part, ma clinique s’appuie davantage sur des modèles psychodynamiques prenant en compte le sujet dans sa globalité, d’où des prises en charge psychomotrices ciblées, en groupe ou en individuel.

Lactobacillus delbrueckii subsp. delbrueckii TUA4408L has the ability to grow and ferment soymilk and is able to modulate the innate immune response of intestinal epithelial cells in vitro. These two properties prompt us to evaluate whether the soymilk fermented with the TUA4408L strain can induce beneficial immunomodulatory effects in vivo. For this purpose, pigs were selected as a preclinical model. The studies performed here demonstrated that the L. delbrueckii subsp. delbrueckii TUA4408L-fermented soymilk (TUA4408L FSM) reduced blood markers of inflammation and differentially regulated the expression of inflammatory and regulatory cytokines in the intestinal mucosa. These immunological changes induced by the TUA4408L FSM were associated to an enhanced resistance to pathogenic Escherichia coli and an improved grow performance and meat quality of pigs. The experiments and analysis in our study indicate that the immunobiotic TUA4408L FSM could be an interesting non-dairy functional food to beneficially modulate the intestinal immune system, improve protection against pathogens and reduce inflammatory damage. The preclinical study carried out here in pigs could have a better correlation in humans, compared to a rodent model. However, the clinical relevance of these findings still needs to be confirmed by further research, for example, in controlled human challenge studies.
Radiological correlation of mechanism of intravascular migration of the ventriculoperitoneal shunt and technical considerations for endovascular retrieval

Published: January 2022

Migration of ventriculoperitoneal shunt into the pulmonary artery is a rare complication that can lead to shunt malfunction and cardiopulmonary complications. This case illustrates the significance of accidental transvenous placement of the shunt. Identification of the transvenous course of the catheter on cross sectional imaging can predict future catheter migration and also aid at surgical extraction. Formation of knot within the distal portion of the shunt catheter during migration or endovascular retrieval can occur, therefore measures to retrieve with knot and adhesions should be factored in before.
Impacto del confinamiento por COVID-19 en las plataformas de préstamo digital: el caso de GaliciaLe
Authors: Sánchez-Muñoz Elena
Published: January 2022

Las plataformas de préstamo electrónico cobraron una mayor relevancia durante el confinamiento por COVID-19, constituyéndose en una alternativa ante el cierre temporal de los servicios presenciales de las bibliotecas públicas. Se analiza el impacto de esta cuarentena en el incremento de las altas de usuarios, lectores activos y préstamos a partir de los datos generados por la plataforma de préstamo electrónico GaliciaLe, así como la repercusión de las medidas que se implantaron para facilitar el acceso de los ciudadanos a la lectura digital durante el estado de alarma. Los datos muestran un notable incremento en los indicadores analizados y permiten concluir que los servicios de préstamo digital han contribuido a suplir parcialmente a las bibliotecas públicas en la misión de promoción de la lectura que tienen encomendada estos centros. Así mismo, se discute la capacidad de las plataformas de préstamo electrónico para mantener su progresión al alza tras el confinamiento.

La siguiente investigación analiza las publicaciones científicas de estudios de género a nivel mundial en revistas seleccionadas indexadas en Web of Science (WOS) entre 2008 y 2018. Los objetivos son indagar sobre la dinámica de participación de las y los autores dentro de esta área de conocimiento y que tópicos investigan, por separado y en conjunto. Para esto, se utilizan algoritmos de clasificación de sexo y de modelado de tópicos. Los resultados muestran que los estudios de género son una de las áreas de investigación más feminizadas y por ende con mayor brecha de género, además destacan que no hubo cambios relevantes dentro del periodo analizado. Los tópicos identificados permiten segmentar los tipos de autoría: ellas se especializan en feminismo, política, violencia, entre otros, ellos no tienen ninguna especialización y la autoría en conjunto lo hace en áreas asociadas a la medicina/salud y estadística/metodología.

The web is one of the primary sources of information for finding learning oriented documents. In addition, the main suitable way to find information and documents on the Internet is by using search engines. Search engines are constantly improving in terms of selection algorithms and in terms of the Human Machine interface (HMI). Also, these search engines are the basis of a new field of research called Search-As-Learning. The Search-As-Learning explores information search environments to enhance learning during user search tasks. This work focuses on our view of the state of the art in the field of Search Engines in learning context and Search-As-Learning, stressing on the most recent research. We conclude by highlighting the current shortcomings on improvement of the learning aspect within search engines, and present next work which will be the association of a layer above the traditional search engines to promote the appropriation of content during search task for a learning context

Published: January 2022

Despite the great success of Massive Open Online Courses (MOOCs), the success rate of learners remains very low. Therefore, a lot of research has been done to understand and solve this abandonment problem. This work is part of the same effort which aims to improve learning in MOOCs. We offer an intelligent system capable of assisting the learner by providing answers to all his questions on the subjects covered in the MOOC. The architecture of our system is based on new advances in artificial intelligence, in particular the applications of deep learning in the field of natural language processing (NLP). The results obtained are quite interesting and demonstrate the relevance of our solution.

Published: January 2022

The thinking and inquiry abilities of students can be improved effectively only through practical exploration and personal experience. To improve the key competences and promote individual development of students, it is important to arrange experiential teaching pertinently, and handle the learning problems timely, referring to the results of itinerary assessment. This paper explores the influence of experiential teaching and itinerary assessment on the improvement of key competencies of students. Firstly, a regression model was established to evaluate the improvement of students’ key competencies, based on stepwise regression. Next, the Iterative Dichotomiser 3 (ID3) model was adopted to classify the tuple of each test sample or research object. Finally, the association rule mining technique was applied to the benchmark evaluation of the improvement of students’ key competencies, and the three benchmark evaluation models were synthetized into an integrated model. The effectiveness of the proposed model was demonstrated through experiments.
Posiciones ideológicas de los periódicos valencianos durante el Trienio Liberal (1820-1823)
Authors: León Navarro Vicente
Published: January 2022

El presente trabajo se centra en el conocimiento y análisis de la prensa del Trienio Liberal en Valencia a través de las afinidades o enfrentamientos de los propios periódicos. Desde marzo de 1820, amparados por la libertad de imprenta, surgen periódicos a favor y en contra del nuevo régimen liberal con la intención de influir en la opinión pública a favor de sus ideas. Y aprovechan sus páginas para incluir noticias de los que salen a la luz o de los que se extinguen, de sus redactores, de sus precios y de la tendencia ideológica. Algunos fueron efímeros y otros se mantuvieron durante todo el periodo acomodándose a las circunstancias políticas y, salvo excepciones, se alimentaron de la prensa foránea.

Published: January 2022

On présente dans ce travail une description générale de  El Grito de Riego (8-I-1823/17-VI-1823). Ce périodique gaditan peu connu du Trienio Liberal témoigne dans ses pages de la situation politique confuse qui caractérise la première moitié de l'année 1823 au cours de laquelle est patente la division du libéralisme.  Journal modéré, El Grito de Riego combat les intentions prêtées aux «comuneros» de s'emparer du pouvoir, tout en dénonçant le fait que les divisions entre les divers secteurs modérés contribuent à l'affaiblissement du système politique constitutionnel. L'usage de la littérature comme arme politique est particulièrement important dans cette publication et nous lui prêtons une attention toute particulière.
Las fuentes de la Gaceta Española (abril – octubre 1823), la gaceta de un gobierno itinerante y sitiado
Authors: Larriba Elisabel
Published: January 2022

Face à l’imminence de l’invasion française et sur ordre des Cortès, la famille royale, le gouvernement et les principales institutions furent transférés à Séville où ils firent leur entrée le 10 avril 1823. La Gaceta Española fondée dès le lendemain devint le nouvel organe de presse du gouvernement constitutionnel. Au service d’un gouvernement itinérant et bientôt assiégé, la Gaceta Española (Séville – Cadix, avril-octobre 1823) dut faire face à bien des problèmes dont la difficulté d’accès à des sources d’information diversifiées et de qualité en contexte de guerre civile. Cet article vise à préciser quelles furent les sources auxquelles les rédacteurs purent accéder, quel type d’information ils livrèrent à leur public et dans quelle mesure la difficulté d’accès aux sources conditionna sur leurs pratiques journalistiques et leur écriture.
Propagande et censure dans la presse nationaliste marocaine sous le protectorat espagnol
Authors: Velasco de Castro Rocío
Published: January 2022

Ce travail a pour but de contribuer à l’étude de la presse dans le Maroc colonial et, plus concrètement, dans la presse nationaliste publiée en arabe durant le protectorat espagnol. Son principal objectif est d’offrir au lecteur ne connaissant pas cette langue un premier contact avec les revues et journaux nationalistes qui acquerra une continuité dans des textes postérieurs. Autorisés par l’administration coloniale espagnole, les responsables marocains de ces publications essayèrent de maintenir un difficile équilibre entre la diffusion de leurs revendications et la censure imposée par les autorités espagnoles. Celles-ci réalisèrent une série de concessions au nationalisme dans le cadre d’une politique culturelle avec, entre autres, l’existence d’une presse arabe, conçue à tout moment comme un élément de propagande du travail civilisateur espagnol. À cette fin, nous avons réalisé un parcours historique qui comprend une liste des publications, leurs principales lignes éditoriales, quelques exemples de cet équilibre précaire et dans quelle mesure pourrait être considérée exceptionnelle la publication et diffusion du journal al-Oumma. De cette vue panoramique se déduit le point de vue marocain, peu connu jusqu’à présent ; nous soulignons l’importance de l’instrumentalisation de la presse et son rôle ambivalent dans la politique indigène ; et nous proposons de nouvelles approches et thématiques d’étude concernant la presse du protectorat espagnol.
Tropes of Transculturality
Authors: Conrad Michael A.
Published: January 2022

Inspired by central ideas of Mediterranean studies, the chapter attempts a comparative examination of typical motifs and patterns as identifiable in royal politics aspiring to organize the multiethnic societies of medieval Sicily and Castile. Far from being conceived as a conclusive study, the text is intended as a first meta-methodological exploration of the possibilities, strengths, and limitations of comparisons between separate Mediterranean cultures within the transcultural framework. At the same time, it gathers historic details under the rubrics of tropes found in historic narratives that are suggestive for comparisons between the situations in Sicily and Castile, in particular during the reigns of Roger II and Alfonso X, who both share astonishingly similar traits, including royal patronage, political pragmatism, the organization of multiculturality through legalism, and the legitimization of royal power based on historicistic myths.
Negotiating the Memory of the American Civil War
Authors: Shackel Paul
Published: January 2022

The American Civil War, which occurred over 150 years ago, changed the social, economic, and political nature of the United States. Over the past century, the United States commemorated the Civil War with the development of many national historical battlefield parks. However, the struggle between the different interest groups continue to plague a unified vision of the event. It became clear that commemorating the Civil War is not only about the past but also about the present and the future. Identifying the events that shape the dominant memory and recognizing the undercurrents that challenge the official memory of any event are important for understanding the dynamics in memorialization. What we see on the commemorative landscape today is only one frame of a long filmstrip of changing memory and meaning – one that will be very different a decade or two from today. Understanding the concept of memory is an important vehicle for answering this question.

Cultural contact results in cultural friction since a culture, like an organism in the face of a threat, goes into the so-called 3Fs mode: fight, flight, or freeze. Academically, one of the cultures, usually the weaker, may acculturate, may be assimilated, or it may reject the other culture. It is also possible for no cultural conflict when cultures meet, for instance the Tungus-Cossack contact. Hausa people were colonised by the British and ruled indirectly for half a century. This had a great impact on many aspects of the culture leading to changes in the society, such as the transformation of the economy and the consequent social implications. Despite these changes, Hausa art and architecture remained, if largely uninfluenced, duly unmindful of Western art and architecture. Between 1920 and 1940, Hausa architecture reached its zenith according to one scholar. This chapter explores the reasons behind this cultural resilience and hypothesises that Hausa culture has within it the disposition and inclination that make such a dispensation not only possible but predictable.

Authors: Alp Sermin Çakıcı
Published: January 2022

This chapter assesses the relationship between the cultural and spatial character of missionary schools in Bursa, an Ottoman city that increasingly witnessed missionary activities during the 19th and 20th centuries. First, the justifications and outcomes of the Ottoman educational system reforms are briefly explained, as are the new patrons and their motivations for training members of minority communities in Ottoman towns. Then, this chapter examines the spatial harmony of the missionary schools with 19th-century Ottoman housing architecture, as seen in examples from Bursa. The interactions and relationships between different cultures and lifestyles are expressed in these new educational institutions. The missionary schools of Bursa, although mostly non-extant, are part of the architectural heritage of Bursa and are important constructions that highlight the interactions between the different cultural ideas and traditions that compose the old neighborhoods of this Ottoman town.

Due to the recent COVID-19 pandemic, there has been a renewed interest in expanding the capabilities of remote collaboration tools. Studies show the importance of noticing peripheral cues, pointing to or manipulating real-world objects in face-to-face meetings. This case study investigated the opportunities of combining traditional video conferencing with a multi-user VR platform to enable the interactive collaborative design of a VR training experience between multiple stakeholders working from their homes. In this article, the authors reflect on the experience and contribute a fully online and immersive collaborative design workflow for future VR development projects. The authors believe this workflow is of benefit for remote collaboration in general, but particularly in severely restricted environments when face-to-face meetings are impossible.

Published: January 2022

The internet is one of the most indispensable tools in the present Information Age. It has positively transformed the way the world operates; however, it has also provided a means by which cybercrimes are perpetuated. As people use the internet, they also become more susceptible to internet risk. A number of previous studies have reported adolescents' susceptibility and coping skills within and outside Nigeria. There is, however, a dearth of information on cybercrime vulnerability and exposure among adolescents in Osun State, Nigeria. This present study adapts the routine activity theory to investigate the cybercrime exposure of secondary school students in Osogbo, the capital of Osun State, Nigeria. This study adopted a survey research method. The study revealed considerable levels of cybercrime exposure among public senior secondary school students in Osogbo. It was recommended amongst others that the students should be enlightened on positive use of the internet in order to militate against harm by cybercrime perpetrators.
Expediting ICT Policy Implementation in Malawi Through Public-Private Partnership
Authors: Makoza Frank
Published: January 2022

This paper analysed the role of public private partnership (PPP) in expediting ICT policy implementation. The study used the case of Malawi as an example of a low-income status country in Africa. Data for the study was gathered through key informant interviews and verified using secondary data. The findings showed that public private partnership supported the development and endorsement of the ICT policy as a priority of government activities. Further, the public private partnership supported ICT sector improvements in legal and regulatory frameworks, human capacity, telecommunications infrastructure, and ICT access in public institutions. The government benefited from the external parties in supporting the ICT investment programs. To some extent, ICT policy implementation focused more on the strategic level of government programs and the supply side of the ICT sector. The study offers insights into how the public private partnership supported execution of ICT policy programs, processes, and politics in the context of a developing country.

The COVID-19 pandemic has resulted in the urgent need for the Nigerian Government to embrace digital economy at all cost. Countries with digitised economy have been able to easily adopt to the challenges that the pandemic has brought, such as eLearning for the education sector and e-business for the business sector. Although, this innovation comes along with a lot of cyber-attacks by cybercriminals resulting for the need to establish adequate cybersecurity measures. Nigeria has gravely felt the impact of the COVID-19, businesses have been shut, countries have shut their borders, thus making it impossible for Nigerian Government/Businesses to access other country's products most especially China. The paper reviews the digital economy of some developed nations and their cybersecurity measures to sustain this innovation. The study further highlights how digital economy has contributed to the Gross Domestic product of most Nations, thus serving a means of diversification for most nations.

The Dynamic Panels With Threshold Effect of China's OFDI on Host Country Technological Progress
Authors: Tan Sai
Published: January 2022

Using the dynamic panel threshold model and data of 41 countries along “the Belt and Road” from 2003 to 2017, this paper empirically tests the impact of China’s outward foreign direct investment (OFDI) on technological progress of these countries and its threshold effect. The results show that OFDI exerts different effects on technological progress of countries along the route within different thresholds range. Based on the classification of different country types, when FD is below than the threshold value, China’s OFDI in transitional and developing countries has no significant impact on their technological progress, while developed countries have a more significant positive correlation; other, when FD is higher than the threshold value, both types of countries are significantly positively correlated, and the coefficient is greater in developed countries than in transitional and developing countries. In further research, it is divided into two periods based on the time node of 2013.
