Pour une analyse conjointe de la programmation des actions et de l’incitation à l’action. Le discours de Daech dans Dar al-Islam
Authors: Rabatel Alain
Published: June 2020

L’article revient sur les conceptions des ‹discours programmateurs/instructionnels› et fait l’hypothèse d’adjoindre à la notion de programmation des actions celle d’ incitation à l’action . Il propose ensuite une analyse de discours des spécificités textuelles, actantielles, modales de ces deux dimensions dans des extraits du journal de Daech, Dar al-Islam , appelant à la mise à mort des mécréants et programmant des actions à cette fin. Enfin, il justifie la subordination de la programmation des actions à l’incitation à l’action, lorsque l’action finale programmée ne va pas de soi, obligeant le programmateur à la justifier et laissant à l’interprète (qui n’est plus un simple exécutant) une autonomie dans la programmation des actions.
Qu’est-ce que programmer par un mode d’emploi de jeu vidéo ?
Authors: Halté Pierre , Goux Mathieu
Published: June 2020

Nous étudions dans cet article deux modes d’emploi de jeu vidéo, publiés en 1987 et 2000, et interrogeons leur nature programmatrice sous l’angle de plusieurs critères linguistiques. Nous opérons une distinction entre la catégorie des ‹discours d’incitation à l’action›, à laquelle ces modes d’emploi sont souvent rattachés, et celle des ‹discours programmateurs›. Ces manuels élaborent un cadre programmant les actions ‹possibles› du joueur, sans qu’elles ne soient ‹obligatoires›. Ce cadre est constitué de stratégies d’identification du joueur et de l’avatar, d’un système modal spécifique et d’une séquentialité narrative permettant d’orienter le joueur vers un objectif final.
Réduire la stigmatisation des salariés reconnus handicapés : exemple d’une action de sensibilisation en entreprise
Authors: Schuhl Jennifer , Chatard Armand , Lambert Éric
Published: June 2020

Cette étude vise à apporter une validité scientifique à une action de sensibilisation au handicap dans une grande entreprise française. Elle s’inscrit dans le champ de la psychologie expérimentale, et a pour but d’apporter un éclairage psychosocial à la problématique de l’insertion professionnelle des personnes reconnues handicapées. Des participants volontaires se sont inscrits à un atelier de sensibilisation au handicap dans lequel ils se sont mis en situation de handicap au cours d’un atelier de cuisine. Ils ont rempli une échelle du jugement social s’intéressant à la compétence, à la chaleur et au courage des personnes handicapées, perçus par les salariés, avant et après leur participation à l’atelier. Les résultats ne traduisent pas d’amélioration significative de la tendance à considérer les personnes en situation de handicap comme chaleureuses, mais montrent que les salariés de l’entreprise ont une plus grande propension à considérer ces personnes comme courageuses et compétentes. Ces résultats sont encourageants et permettent de discuter des bonnes pratiques à mettre en place en entreprise pour lutter contre les stéréotypes et les préjugés afin de faciliter l’inclusion des personnes en situation de handicap au travail.
Intraoperative Femoral Fractures Associated With Cementless Total Hip Arthroplasty
Authors: Mallory Thomas H , Kraus Thomas J , Vaughn Bradley K
Published: June 2020

ABSTRACT: Between 1982 and 1986, 56 femoral fractures associated with cementless total hip arthroplasty (THA) were evaluated and compared to a randomly selected cementless THA control group without fractures. Depending upon the femoral shaft location, these fractures were classified as Types I, II, or III. There were 45 (80%) Type I, 9 (16%) Type II, and 2 (4%) Type III fractures. Patient evaluations were quantified using a modified d'Aubigne-Harris scoring system. Nonparametric statistical methodology was used tor fracture and control group comparisons. Treatment protocols were divided into various modalities, depending upon fracture classification. Type I and Type II fractures have no long-term prognostic hazards associated with them (P > 0.1), while Type III fractures appear to have analogous clinical results (sample size was too small for statistical analysis).

Authors: Watanabe Wataru , Sato Kozo , Itoi Eiji , Yang Kunitaka , Watanabe Hidetoshi
Published: June 2020

Abstract

The relationship between pelvic tilt and acetabular femoral head covering was determined in 38 patients with decreased lumbar lordosis. Posterior pelvic tilt and acetabular femoral head covering were measured on radiographs taken in both supine and standing positions. Previously reported normal values obtained from 96 patients were used as controls. Posterior pelvic tilt increased (P<.01) in patients with decreased lumbar lordosis and anterior acetabular femoral head covering decreased (P<.0001) compared with the controls. These differences were more remarkable in the standing position than in the supine position. Patients with decreased lumbar lordosis have decreased femoral head covering, especially in the standing position.
Quasineutral limit for the compressible two-fluid Euler–Maxwell equations for well-prepared initial data
Authors: Li Min , Pu Xueke , Wang Shu
Published: June 2020

In this paper, we study the quasi-neutral limit for the compressible two-fluid Euler–Maxwell equations for well-prepared initial data. Precisely, we proved the solution of the three-dimensional compressible two-fluid Euler–Maxwell equations converges locally in time to that of the compressible Euler equation as $ \varepsilon $ tends to zero. This proof is based on the formal asymptotic expansions, the iteration techniques, the vector analysis formulas and the Sobolev energy estimates.
A $ C^0P_2 $ time-stepping virtual element method for linear wave equations on polygonal meshes
Authors: Huang Jianguo , Lin Sen
Published: June 2020

This paper is concerned with a $ C^0P_2 $ time-stepping virtual element method (VEM) for solving linear wave equations on polygonal meshes. The spatial discretization is carried out by the VEM while the temporal discretization is obtained based on the $ C^0P_2 $ time-stepping approach, leading to a fully discrete method. The error estimates in the $ H^1 $ semi-norm and $ L^2 $ norm are derived after detailed derivation. Finally, the numerical performance and efficiency of the proposed method is illustrated by several numerical experiments.

Authors: Ahmed Muhammad Mashhood , Maglaras Leandros , Ferrag Mohamed Amine
Published: June 2020

Healthcare is one of the most targeted industries by cybercriminals. The healthcare sector is far behind in cybersecurity as compared to other organizations. The vulnerabilities in the system open the door for cybercriminals to exploit it and get unauthorized access into the system or network to do a malicious activity. Healthcare should have to take cyber threats seriously and follow a security framework that detects and mitigates cyber threats. This chapter presents all cyber threat actors that exist in the healthcare sector, common cyber-attacks that can be launched against all actors, and real incidents that took place during the past years. Based on these, the authors propose in a tabular form a set of recommendations that can be used as countermeasures against any type of attack.
Evaluating a Teaching Intervention for Teaching STEM and Programming Concepts Through the Creation of a Weather-Forecast App for Smart Mobile Devices
Authors: Papadakis Stamatios
Published: June 2020

The last two decades have necessitated the need for an interdisciplinary approach to mathematics, science, and technology (STEM) as contemporary problems are too multidimensional to be tackled by a single scientific discipline as was the case with classical school curricula. Teaching programming has the potential to contribute to this vision as it is effective in helping students develop critical thinking skills. This work presents an educational approach that combines STEM learning with the basic concepts of programming through the creation of a weather-forecast app for smart mobile devices with the programming environment MIT App Inventor. This approach was implemented with second grade high school students as a school project. The evaluation results are considered encouraging as the students engaged in authentic learning activities and research related to the STEM field while, at the same time, enhanced their interest and knowledge in pursuing careers involving programming, science, technology, engineering, and mathematics.

The Role of Unplugged Coding Activity in Developing Computational Thinking in Ages 6-11
Authors: Lombardi Gaia
Published: June 2020

Coding is a spreading teaching methodology that is involving more students and teachers all over the world. But how can the practice of coding affect the development of computational thinking strategies in early years? The author, a primary school teacher, will investigate the Italian experience, believing that it may constitute an excellent field of study on the matter thanks to the enormous enthusiasm with which coding was received by the teachers, capable of renewing their teaching practices, particularly in primary school. This is a movement born from below, from the spontaneous participation of teachers, and which, in many cases, has been substantiated in what can be defined as unplugged activities, without the use of electronic technological tools.

Authors: Chatzopoulos Avraam , Kalogiannakis Michail , Papoutsidakis Michail , Psycharis Sarantos , Papachristos Dimitrios
Published: June 2020

In this chapter, the authors present their research on how P12 students apply computational thinking (CT) skills when they are assigned simple science, technology, engineering, mathematics (STEM) problems, which they are called upon to solve with the help of educational robotics (ER) activities. The reason for this research was the high participation and increased interest shown in an ER event, where distributed questionnaires recorded students' views on ER, STEM, and CT. Their answers were the spark to conduct a pilot study on primary school students in the form of an experiential seminar to investigate the possibility of developing their CT skills by applying ER activities when they are asked to solve authentic STEM problems. The results showed that students may develop CT skills when involved in ER activities and that educational robots enhance students' engagement with programming and create a more favorable environment for developing students' CT skills.

Authors: Psaridou Vasiliki , Molla Marina
Published: June 2020

The aim of this educational school project was to inspire young children around STEMs and for STEM professions to empower them to cope with stereotypes in this field and discrimination in the professional field to work together in favour of integration and diversity (in and outside the school). That is why the effort to build a ramp for disabled people was chosen as a single topic. This project is a collaborative project involving two minority primary schools and a Turkish high school. The topic was covered by a cross-curricular approach to STEM. STEM professionals visited one of the schools, where they presented their profession and received questions from students via teleconference. A workshop of engineering followed. Students used traditional and modern engineering tools to make measurements. The data they collected from their measurements were processed in a mathematics lab, where they designed a ramp for the school.
The Role of Digital Fabrication in Today's Society
Authors: Tyler-Wood Tandra Lea
Published: June 2020

Digital fabrication and the “maker movement” can play a major role in bringing computational technology into the 21st century classroom. Digital fabrication is defined as the process of translating a digital design developed on a computer into a physical object or any process for producing/printing a three-dimensional (3D) object. The maker movement is a platform for today's futuristic artisans, craftsmen, designers and developers to create, craft, and develop leading ideas and products. Digital fabrication and “making” could provide a new platform for bringing powerful ideas and meaningful tools to students. Digital fabrication has the potential to be “the ultimate construction kit.” Digital fabrication has strong ties to the maker movement. Maker spaces provide students with safe areas that allow students to safely use digital fabrication to make, build, and share their creations. This chapter will look at the role that digital fabrication can play in incorporating computational technology into the K-12 classroom.

Published: June 2020

The goal of this work is to develop a key exchange solution for IPsec protocol, adapted to the restricted nature of the Internet of Things (IoT) components. With the emergence of IP-enabled wireless sensor networks (WSNs), the landscape of IoT is rapidly changing. Nevertheless, this technology has exacerbated the conventional security issues in WSNs, such as the key exchange problem. Therefore, Tiny Authenticated Key Exchange Protocol for IoT (TAKE-IoT) is proposed to solve this problem. The proposed TAKE-IoT is a secure, yet efficient, protocol that responds to several security requirements and withstands various types of known attacks. Moreover, TAKE-IoT aims to reduce computation costs using lightweight operations for the key generation. The proposed protocol is validated using the automated validation of internet security protocols and applications (AVISPA) tool. Hence, results show that TAKE-IoT can reach a proper level of security without sacrificing its efficiency in the context of IoT.

Published: June 2020

To control water resources in many domains such as agriculture, flood forecasting, and hydro-electrical dams, forecasting water level needs to predict. In this article, a new computational approach using a data driven model and time series is proposed to calculate the forecast water level in short time. Concretely, wavelet-artificial neural network (WAANN) and time series (TS) are combined together called WAANN-TS that encourages the advantage of each model. For this real time project work, Yen Bai station, Northwest Vietnam was chosen as an experimental case study to apply the proposed model. Input variables into the Wavelet-ANN structure is water level data. Time series and ANN models are built, and their performances are compared. The results indicate the greater accuracy of the proposed models at Hanoi station. The final proposal WAANN−TS for water level forecasting shows good performance with root mean square error (RMSE) from 10−10 to 10−11.

Perceptions of Machine Translation and Computer-Aided Translation by Professionals and the General Public
Authors: Wang Binhua , Ping Yuan
Published: June 2020

This article examines perceptions of MT and CAT among translation professionals and the general public by surveying 124 articles published in the professional journals of ITI Bulletin and MultiLingual and in the Chinese media between 2017 and 2019. Through framing analysis, the following frames about MT and CAT are identified: progress, quality, threat, limitation, cooperation, economic factors, and ethics. Through qualitative analysis of prominent frames, it is also found that attitudes vary between the professional journals and the media about the role of MT as related to human translators. While ITI Bulletin holds a generally conservative attitude, MultiLingual takes a more positive stance towards the applications of MT, and the Chinese media generally hype MT as a potential threat to HT but promote human-machine cooperation as the way out. This study also shows that the ethical and legal issues involving MT and CAT have not been addressed adequately.
Making Connections Through Knowledge Nodes in Translator Training
Authors: Tian Lu , Zhu Chunshen
Published: June 2020

This study defines translator training as a pedagogical scheme to help learners build up a knowledge network that should sustain their professional competence. It explores specifically how a computer-assisted mode of training may contribute to systemizing such a scheme with special reference to literary translation. The tool used for such training is Textwells, an online translation teaching and learning platform that weaves textual and translation-related concepts, phenomena, and methods as “knowledge nodes” into a network to support teaching and learning in different settings. As such, different from the traditional way of arranging a literary translation course according to the subgenres of literature, this approach, facilitated by the online platform, organizes the teaching contents along a series of knowledge nodes that are deemed fundamental to the production of a literary target text. In particular, this paper gives a detailed report about the course design and teaching procedures, using the rhetoric component as an illustrating case.

Batch Electrocoagulation Treatment of Peat Water in Sarawak with Galvanized Iron Electrodes
Authors: Rahman Nazzeri Abdul , Tomiran Nur Afifah , Hashim Aiman Hakim
Published: June 2020

Peat water is an abundant water resource in Sarawak where some of the coastal areas in Sarawak still utilize peat water for domestic usage. Peat water contains natural organic matters especially humic substances which include humic acids. Humic acids contribute to the brown color of peat water and can cause diseases such as stomach cancer, blackfoot disease and etc. if consumed by human. Electrocoagulation is an alternative to conventional water treatment methods which have the advantages of being environmental friendly, minimal sludge production and no addition of chemical substances. The aims of this study are to fabricate a desktop scale electrocoagulation system with galvanised iron electrodes and to investigate the effects of the operating parameters such as inter-electrode distance, applied current density, number of electrodes, and treatment time on peat water in the system. The performance of batch electrocoagulation system in term of their removal efficiency of several parameters such as total organic carbon (TOC), chemical oxygen demand (COD), color and turbidity are evaluated. Through experimental tests conducted, this system successfully removes 98.44% of COD, 92.02% of TOC, 97.92% of turbidity and 99.91% of color by using galvanized iron as an electrode at current density of 25 A/m2in 30 minutes with 10 galvanized iron electrodes. Despite the fact that there is a small amount of iron ions and zinc ions remained in the treated peat water which are 0.001mg/l and 0.0442mg/l respectively, these concentrations are far below the standard limits imposed by Malaysia Ministry of Health (MOH). Generally, all the parameters studied meet the standard limit imposed by MOH except for total organic carbon. This is particularly due to the improper filtration system adopted in this study. The total operating costs for 252 in 30 minutes treatment time of 10 electrode plates is RM 8.75 per . Overall, the study have successfully designed a batch electrocoagulation system to treat peat water by using galvanized iron for domestic usage.

Authors: Hossen Md. Faruk , Hamdan Sinin , Rahman Md. Rezaur , Sultan Md. Tipu
Published: June 2020

The jute polyethylene composites were developed using the hot-press technique with different fiber weight ratios. Due to the hydrophilic nature of fiber, it exhibited poor interfacial interaction to hydrophobic polymer matrix. In order to enhance the interfacial interaction between fiber and polymer, the benzene diazonium salt (BDS), propionic anhydride (PA), and 3-isocyanatopropyl triethoxysilane (silane) treated jute were used for the manufacturing of composites in this study. The chemical resistance tests of prepared composites were performed in order to probe whether these are resistant to various chemicals such as: acids, alkalis, and solvents. The effect of chemical treatments of the composites have been investigated. It was observed that the fabricated composites were resistant to all chemicals except carbon tetrachloride. The treated jute composites showed higher chemical resistance than raw jute composite and silane treated jute composite yield the highest resistance which can be suggested for making the water and chemical storage tanks.

Published: June 2020

Heterogeneous catalyst has been viewed as a promising catalyst for biodiesel production. This study employed Turritella terebra (TT) shell as a source for synthesizing heterogeneous CaO catalyst for biodiesel production via transesterification by utilizing chicken fat as a feedstock. The TT shell CaO catalyst was characterized and its catalytic performance was studied. The spectrographic methods that include FTIR, SEM, PSA, and BET-BJH were employed for characterization of the synthesized CaO. The TT shell CaO catalyst optimally produced chicken fat biodiesel (CFB) with reaction parameters at catalyst concentration of 4 wt%, chicken fat to methanol molar ratio of 1:12, reaction temperature of 60°C, and reaction time of 90 min. The optimal yield was 94.03% and the TT shell CaO catalyst still yield 79.19% of CFB on the fifth cycle of reaction. This study has implied that TT shell is a feasible and attractive renewable source of heterogeneous CaO catalyst for biodiesel production.

Published: June 2020

IL-23 promotes autoimmune disease, including Th17 CD4 T cell development and autoantibody production. In this study, we show that a deficiency of the p19 component of IL-23 in the autoimmune BXD2 (BXD2-p19−/−) mouse leads to a shift of the follicular T helper cell program from follicular T helper (Tfh)–IL-17 to Tfh–IFN-γ. Although the germinal center (GC) size and the number of GC B cells remained the same, BXD2-p19−/− mice exhibited a lower class-switch recombination (CSR) in the GC B cells, leading to lower serum levels of IgG2b. Single-cell transcriptomics analysis of GC B cells revealed that whereas Ifngr1, Il21r, and Il4r genes exhibited a synchronized expression pattern with Cxcr5 and plasma cell program genes, Il17ra exhibited a synchronized expression pattern with Cxcr4 and GC program genes. Downregulation of Ighg2b in BXD2-p19−/− GC B cells was associated with decreased expression of CSR-related novel base excision repair genes that were otherwise predominantly expressed by Il17ra+ GC B cells in BXD2 mice. Together, these results suggest that although IL-23 is dispensable for GC formation, it is essential to promote a population of Tfh–IL-17 cells. IL-23 acts indirectly on Il17ra+ GC B cells to facilitate CSR-related base excision repair genes during the dark zone phase of GC B cell development.

For numerous patients suffering from pathologies that irreversibly damage organs and tissues, transplantation is the best therapeutic solution, and in several cases the only possible one. In this context the present study has set the objective to analyze the attitude of the respondents towards donation in relation to their education levels. A questionnaire was elaborated and administered. A range Linkert-score was associated with each question indicating as 0 the minimum preference and 5 the maximum preference. For each question participants had to indicate a single answer among proposals. Χ2 test among answers collected was assessed in order to statistically verify the significance between answers given by the two groups as regards organs donation. The recruited group was made up of 203 students of which 129 were girls (64%) and 74 were boys (36%). The youngest student was aged 17 and the oldest 21, mean age was 18.58±1.89 years. The population group considered in this study consisted of 203 subjects, of which 117 (58%) females and 86 (42%) males. The youngest person interviewed belonging to population group was aged 22 and the oldest was 87 years old, the mean age was 51.03±14.02 years. Our study revealed the attitude towards donation with a greater degree of consensus that has been demonstrated within the population rather than within students.

Upfront Maintenance Poly(Adenosine Diphosphate Ribose) Polymerase Inhibitors in Ovarian Cancer: A Ray of Hope or Just a Mirage!
Authors: Pandey Avinash , Ghosh Joydeep
Published: June 2020

Poly(adenosine diphosphate ribose) polymerase inhibitors (PARPis), when used in patients harboring tumor with homologous recombination deficiency, with or without BRCA mutation, have shown favorable outcomes in relapsed, advanced metastatic breast and ovarian cancers. Olaparib, niraparib, and rucaparib have been approved as maintenance therapy in platinum-sensitive, relapsed, high-grade epithelial ovarian cancer (EOC) responsive to platinum doublet. Olaparib and rucaparib as monotherapy are also indicated in patients who have progressed on three or more lines of chemotherapy, irrespective of platinum sensitivity, in germline or somatic BRCA 1/2-mutated, PARPi-naive patients. Recently, four large multicentric, international Phase III randomized clinical trials have reported outcomes of PARPi in first-line advanced EOC as maintenance therapy either alone or in combination with bevacizumab. Previously bevacizumab, pazopanib, nindetanib, or maintenance chemotherapy in first-line setting has resulted in modest improvements in progression free survival, albeit with significant toxicities and poor cost-effectiveness. We offer in this review to dissect the data pertaining to randomized clinical trials of PARPi use as maintenance therapy in upfront EOCs and ruminate about its role in the contemporary management of ovarian cancers.

A multistage sampling technique was employed to select and administer semi-structured questionnaires to three hundred and sixty-six (366) households. Descriptive statistics and binomial logistic regression algorithm were used to analyze the data. The results revealed that majority of the households were willing to learn about the natural heritage, preserve the culture, provide environmental education for tourists, and participate in mountain tourism-related employment. Among the four indicators of residents’ willingness to participate in mountain tourism development, households were willing to participate in mountain tourism planning. The linear regression analysis shows that predictors varied with the four critical indicators - willingness to conserve the natural resources, to preserve the cultural tradition, to sustainable community development, and to participate in the mountain tourism planning and management. This implied that the socio-demography of the residents is pertinent and should be put into consideration for the successful integration of the host community into the decision making framework as well as sustainable planning and development of the ASL for mountain tourism.
Developments and Changes Adversely Affecting Trade Unions in the Hospitality Industry of Zimbabwe
Authors: Ncube Farai , Oni Olabanji
Published: June 2020

This article investigates the changes happening in the tourism and hospitality industry adversely affecting the trade unions and their ability to effectively organise and represent fully their member interest in Zimbabwe. The authors argue that the tourism and hospitality industry remains one of the fastest growing sectors within the global economy that is undeniably extremely labour intensive. While there are two officially registered unions namely the Zimbabwe Catering and Hotel Workers Union (ZCHWU) and the Hospitality and Allied Workers Union of Zimbabwe (HAWUZ), the focus has been on the ZCHWU which has ultimate control, having enjoyed monopoly from the traditional one union one industry approach. Through in-depth interviews and focus group discussions findings reveal legislative and demographics changes, adoption of precarious employment, adoption of new technology and the entry of Chinese accused of being anti-unionism and exploitative in nature as some of the major changes. The study exposes poor working conditions ranging from, long working hours, low salaries, poor safety conditions, intimidation, harassment and massive casualisation of labour calling for trade union intervention. Based on the findings the research maintains that trade union remain relevant in the sector, beneficial to both their members, employers and the clients they serve

Authors: Mutsikiwa Munyaradzi , Zvavahera Promise , Pasipanodya Sheppard
Published: June 2020

The study examines the applicability of Khan and Rahman’s (2017) hotel brand experience scale to the hotel context of Zimbabwe. The study employed a cross-sectional design to collect data from hotel guests. Data analysis was done using exploratory factor analysis and structural equation modelling. The results produced four dimensions of the original scale. In trying to establish the hypothesised relationships between the constructs, the results revealed that two dimensions: hotel ambience and hotel staff competence had a significant and positive influence on intention to continue staying at hotels whereas hotel location and guest to guest experience did not have any significant influence on intention to continue staying at hotels. The study offers hotel managers with the relevant dimensions that they should employ in order to design suitable strategies that enhance guests’ intention to continue staying at hotels.
Un intelectual inquieto. Salvador Sanpere i Miquel y su incidencia en el impulso de las artes decorativas e industriales en Cataluña
Authors: Freixa i Serra Mireia
Published: June 2020

En el año 1870, Salvador Sanpere i Miquel (1840-1915) realizó un viaje a la Gran Bretaña, becado por la Diputación Provincial de Barcelona, que fue uno de los grandes hitos en la renovación de las artes industriales en España según ha aceptado toda la bibliografía especializada. Este trabajo analiza las razones que motivaron tanto éste viaje como otras de las actuaciones posteriores de Sanpere sobre la promoción de las artes industriales, insistiendo en que fueron consecuencia de sus convicciones sociales vinculadas a la ideología progresista y republicana. Sanpere defiende el ejemplo británico como modelo para la renovación de la industria. Insiste también en la necesidad de crear una política de exposiciones, de renovar las enseñanzas de artes aplicadas y de fundar una biblioteca especializada. Otro de los grandes puntos de atención para nuestro autor reside en la necesidad de confeccionar una gramática de ornamentación propia, demostrando una reflexión muy elaborada sobre el concepto de estilo dentro del eclecticismo decimonónico

Vajillas heráldicas de porcelana europea para la aristocracia cubana
Authors: Du Bouchet de la Figuera Juan Carlos
Published: June 2020

"En el siglo XIX se extiende entre las familias de la aristocracia y la burguesía cubana la costumbre de imitar los hábitos y modas, así como los gustos artísticos y decorativos de la nobleza europea, como la de presumir ante sus invitados con lujosos servicios de mesa personalizados. Las ostentosas vajillas encargadas a las más prestigiosas manufacturas de porcelana europeas eran marcadas con escudos de armas, yelmos, coronas y monogramas que denotaban propiedad y poder. La belleza de estas piezas, con una gran diversidad en formas y estilos, les otorga alto interés como elementos decorativos; lo que unido al manifiesto e importante valor documental, patrimonial y artístico que atesoran, en poco tiempo les confirió la categoría de objetos coleccionables.

Mientras que la segunda aborda la propuesta museográfica desde que se produce el traslado al palacete de la duquesa de Santoña de la calle Montalbán, en enero de 1934, hasta su reapertura tras la Guerra Civil, en diciembre de 1940.
Covid-19: l’habitatge protegeix la gent gran a Amèrica Llatina? Argentina i Colòmbia comparades amb Espanya
Authors: Módenes Juan A. , Marcos Mariana , García Diva Marcela
Published: June 2020

En aquest nou paradigma de la covid-19, protegir la població més gran no pot confiar-se només al seu confinament a l’habitatge, i menys encara a Amèrica Llatina. L’estructura de les llars, les característiques de l’habitatge i l’activitat laboral dels coresidents condicionen l’exposició de les persones grans als contagis dins de l’habitatge. Per mesurar aquesta exposició, aquest Perspectives Demogràfiques proposa el càlcul d’un indicador que estima el risc residencial multidimensional, que permet la comparació entre poblacions. Més de la meitat de la gent gran de Colòmbia i un 35% de la d’Argentina es troba sobreexposada a la covid-19 a casa. El nostre estudi demostra que el risc residencial és molt important a Amèrica Llatina, però també significatiu a Espanya pel que, un dels objectius prioritaris en la protecció de les persones grans ha de ser el de minimitzar aquest risc residencial. L’indicador de risc residencial davant la covid-19 pot utilitzar-se per identificar àrees o subpoblacions més exposades dins dels països i guiar la futura acció política davant la pandèmia.
