Youth Unemployment and Underdevelopment in Honduras
Authors: Cáceres Luis René
Published: January 2021

This paper analyzes the determinants and consequences of youth unemployment in Honduras. The study is based on the estimation of error correction models that express youth unemployment in terms of real sector variables. The results indicate that exports, remittances and self employment reduce youth unemployment, while the expansion of the service sector increases it; other results show that youth unemployment is susceptible to economic activity in the other Central American countries, specifically to economic growth in Guatemala, El Salvador and Nicaragua. Youth unemployment exerts negative impacts on Honduras’ productivity and on economic growth. The study also highlights the role of education on preventing youth unemployment and the importance of designing a Youth Agenda that would comprise several initiatives that are of special value to Honduran youth. It is hoped that these results would motivate policy makers and society in general to increase investments in the human capital areas so that youth avoid falling into the traps resulting from unemployment.
A- Optimal Slope Design for Second Degree Kronecker Model Mixture Experiment With Four Ingredients With Application in Selected Fruits Blending
Authors: Kung’u Ngigi Peter , Koske J. K. Arap , Kinyanjui Josphat K.
Published: February 2021

This study presents an investigation of an optimal slope design in the second degree Kronecker model for mixture experiments in four dimensions and its application in blending of selected fruits to prepare punch. The study centers around weighted centroid designs, with the second degree Kronecker model. This is guided by the fact that the class of weighted centroid designs is a complete class in the Kiefer Ordering. To overcome the problem of estimability, a concise coefficient matrix is defined that aid in selecting a maximal parameter subsystem for the Kronecker model. The information matrix of the design is obtained using a linear function of the moment matrices for the centroids and directly linked to the slope matrix. The discussion is based on Kronecker product algebra which clearly reflects the symmetries of the simplex experimental region. From the family of matrix means, a well-defined function is used to determine optimal values of the efficient developed design. Finally, a demonstration is provided for the case where the design is applied in fruit blending.

Traveling Wave Solutions for Some Three-Species Predator-Prey Systems
Authors: Guo Jong-Shenq
Published: January 2021

In this paper, we present some recent developments on the application of Schauder’s fixed point theorem to the existence of traveling waves for some three-species predator-prey systems. The existence of traveling waves of predator-prey systems is closely related to the invasion phenomenon of some alien species to the habitat of aboriginal species. Three different three-species predator-prey models with different invaded and invading states are presented. In this paper, we focus on the methodology of deriving the convergence of stale tail of wave profiles.
Iodine in Table Salt in the Aseer Region, Southwestern Saudi Arabia
Authors: Patel Ayyub Ali
Published: February 2021

Background: Iodine, a micronutrient that plays a significant role in thyroid hormone synthesis, is essential for normal neurological development. Universal Salt Iodization is a plan advocated by the WHO to ensure sufficient iodine intake by all individuals. No accurate data was available about household coverage with iodized salt and salt iodization adequacy in the Aseer region, southwestern Saudi Arabia. Objectives: To estimate the proportion of households consuming iodized salt in the Aseer region, southwestern Saudi Arabia, and assess salt iodization’s adequacy. Methods: The study was a cross-sectional study on a stratified proportional allocation sample. The household of each child was requested to bring a teaspoonful of table salt consumed in their kitchen. The salt samples were taken in standard, small, self-sealed plastic bags. The Iodine concentration of salt was determined spectrophotometrically. Results: The study included 3038 samples of table salt. Insufficient iodized table salt samples (less than 15 ppm based on the WHO/UNICEF ICCIDD classification) were observed in 22.3% (95% CI: 20.8% – 23.8%) of the samples. Similarly, insufficient iodized table salt samples (less than 70 ppm based on Saudi Standards, Metrology and Quality Organization “SASO” classification) were observed in 75.7% (95% CI: 74.1% – 77.2%) of the study samples. The present study showed that rural areas significantly had higher insufficient table salt samples than urban areas. Conclusions: The study showed that the use of insufficient iodized salt in the region is still common. The accessibility of iodized salt can be achieved through iodized salt’s marketing and sales. Authorities in the Aseer region should play an influential role in forbidding non-iodized salt in the local markets in the Aseer region. Key words: Iodine; Table salt; Saudi Arabia

Published: February 2021

Background: Amputations and ulcers of foot are the main causes of disability, morbidity, physical and emotional costs among diabetics. Management of their risk factors and early recognition can delay or prevent the beginning of any adverse outcomes. Objectives: To assess the levels of knowledge and practice regarding foot care among recently diagnosed diabetic patients. Subjects and Methods: A cross-sectional study was conducted at primary healthcare centers belonging to the Ministry of Health, Muhayil city, Aseer Region, Kingdom of Saudi Arabia (KSA) among recently diagnosed (i.e., before two years) diabetic patients. A study questionnaire (in a simple Arabic language) was used to collect data related to personal characteristics, present history related to diabetes, fasting blood sugar control (mg/dL), provided medical care, assessment of knowledge about foot self-care and prevention of diabetic foot and assessment of patient’s daily practices related to foot self-care. Results: The study included 250 recently diagnosed diabetic patients. Males represented 55.6% of them. Only 14.8% had glycemic control, based on HbA1c level <7%. Generally, 66% of patients had poor knowledge regarding diabetic foot, whereas only 13.6% of them had good knowledge. Good foot care practice was observed among 52% of patients. Young patients (20-30 years old) were more likely to have good foot care practice than those aged over 60 years, p=0.026. Patients with heart diseases were significantly less likely to have good foot care practice compared to those without cardiac diseases, p=0.039. Patients with HbA1c<7% were significantly more likely to express good foot care practice than those with HbA1c 7%, p=0.006. There was a significant association between patients’ knowledge about foot care and their practice, p<0.001. Regarding provided foot-related health care, 90.8% of patients reported undergoing feet examination by their physicians, 63.2% reported that physicians explained to them the importance of foot care and how to perform it (60.0%). Less than half of patients (45.2%) received health educational brochures about foot care Conclusion: Most recently diagnosed diabetic patients in Muhayil City, Aseer Region, KSA have inadequate knowledge and poor practices regarding foot care. Intensive health education regarding diabetic foot care is highly recommended. Key words: Diabetes mellitus, diabetic foot, foot care, knowledge, practice, Saudi Arabia.

Published: February 2021

Objective: Esophageal carcinoma is one of the most lethal and yet least studied malignancies in South Asian region. The aim of our study was to determine the frequency of Esophageal Carcinoma and to identify factors responsible for late stage diagnosis of this malignancy. Methods: A multi-institutional prospective cross-sectional study was conducted at Oncology department, JPMC and Atomic Energy Medical Centre, Karachi. Association between risk factors of delayed diagnosis with ethnic groups, grade and stage of tumour was statistically assessed. Results: A frequency of 3.83% of esophageal cancer was recorded. Squamous cell carcinoma as the most common (80.6%) subtype, moderately differentiated grade in 67.7% and lower 1/3rd involvement was noted in 53.8% cases. Representation of Sindhi speaking ethnicity was 33.3%. First visit to a general physician was within a month of onset of symptoms in 54.8% patients. In 21.5%, first visit was delayed by more than 2 months. Biopsy was delayed in 19.4% cases. Significant association was found between delayed diagnosis and late referral to oncologist (P 0.003), non-availability of laboratory (P 0.018), location of tumour (P 0.000), age and size of tumour (P 0.001). Conclusion: Esophageal carcinoma is a common malignancy with squamous cell carcinoma as the most common subtype. Initial diagnosis of most of the patients was made in the late stage. Important contributing factors of late diagnosis were unawareness of patients, delayed initial diagnostic workup, poor socioeconomic status and late referrals to oncologists by General Physicians. No significant association was observed between ethnicity and grading or staging of tumour.

Insomnia and social network use among secondary school female students in Abha Sector
Authors: Almusa Huda Ali
Published: February 2021

Background: Internet addiction and other problematic internet use behaviors can dramatically affect sleep hygiene, resulting in sleeplessness and other sleep disturbances. Excess internet and social media use are mainly associated with insomnia and increased time spent on the internet leads to the important disturbance of sleep. One psychophysical mechanism that could help to clarify the negative influence of problematic internet use on sleeping habits can be that nighttime computer use causes a state of high arousal, therefore, interfering with the soothing procedures that are essential for sleep. Sleep disturbance may result in stress which in turn affects student’s scholastic performance. Aim: The current study aimed to assess prevalence of internet addiction with its association with insomnia and scholastic achievement among secondary school females in Abha city, Saudi Arabia. Methodology: A correlational cross-sectional approach was applied for the current research. The research targeted all secondary school female students in Abha city. A multistage cluster sample was applied by selecting schools and students from the Directorate of Education in Abha. Self-administered questionnaire sheets were distributed to students in their classes. The questionnaire covered students’ socio-demographic data like age, grade, parents’ education, work, and living conditions. Also, the tool included scales for internet addiction and perceived stress. Scholastic performance was measured by grades in the last year with absenteeism. Results: The study included 3 50 female students whose ages ranged from 15 to 22 years old with mean age of 16.9 ± 1.1 years. Regarding father’s education, 214 students’ fathers were university graduated (61.5%) and 108 (31%) had secondary level of education. Regarding frequency of using social internet, 85.3% of the students reported usual use. Also, 83.9% of the students spend more than three hours daily using social networks. Internet addiction was reported among more than one third of the sampled students. Conclusions & recommendations: In conclusion, the study revealed that more internet addiction was a significant problem among secondary school female students and affected their scholastic achievement and their life due to high stress. Key words: Internet addiction, students. Secondary school, stress, school performance
Visualizing the structure of urban mobility with bundling: A case study of the city of São Paulo
Authors: Martins Tallys Gustavo , Lago Nelson , De Souza Higor Amario , Santana Eduardo Felipe Zambom , Telea Alexandru , Kon Fabio
Published: February 2021

Visualization of urban mobility data can facilitate the analysis and the decision-making process by public managers. However, mobility datasets tend to be very large and pose several challenges to the use of visualization, such as algorithm scalability and data occlusion. One approach to solve this problem is trail bundling, which groups motion trails that are spatially close in a simplified representation. This paper presents the results of adapting and using a recent bundling technique on a big dataset of urban mobility in São Paulo. The results show that bundling allows the visualization of various mobility patterns in the city.
Visualization of Multivariate Data on Surfaces
Authors: Rocha Allan , Alim Usman , Sousa Mario Costa
Published: February 2021

This research builds upon ideas introduced and discussed many years ago that focus on the problem of visualizing multiple attributes on surfaces in a single view. Here we present a new perspective to this problem as well as a solution that allows us to design, visualize and interact with multivariate data on surfaces. Building upon multidisciplinary aspects, we present a new way to visualize multivariate data on surfaces by exploiting the concept of layering. First, we introduce a new real-time rendering technique and the concept of Decal-Maps, which fills a gap in the literature and allow us to create 2D visual representations such as glyphs that follow the surface geometry. Building on this technique, we propose the layering framework to facilitate the multivariate visualization design on surfaces. The use of this concept and framework allows us to connect and generalize concepts established in flat space, such as 2D maps, to arbitrary surfaces. Decal-maps opens up other new possibilities such as the use of interaction techniques. Here we demonstrate this potential by introducing a new interaction technique that allows us to explore multivariate data and to create customized focus+context visualizations on surfaces. This is achieved by introducing a new category of lenses, Decal-Lenses, which extends the concept of magic-lenses from flat space to general surfaces. Finally, this thesis showcases the process of multivariate visual design and data exploration through a series of examples from several domains such as Medicine and Geology.

Du Projet européen à l’Europe des projets: Soixante ans de présence et d’influence françaises à la Banque européenne d’investissement (1958-2018)
Authors: GORDON Bernard
Published: February 2021

This article aims to better define the vectors as well as the objectives of French influence at the European Investment Bank (EIB), a European institution created in 1957 which annually mobilises a volume of funding equivalent to the Commission’s budget. For the main part, French influence was exercised individually, through the French members of the Management Committee as well as the French managers of the Bank, in a context where the French Ministry of Finance, which represents the French government at the Bank’s governing bodies, is sometimes reluctant, often inactive, and exceptionally proactive on new initiatives. Based on visions, models and experiences in which France retained a comparative advantage, this influencewas instrumental in the promotion of key policies in three areas: EIB finances and the promotion of a common currency, the financing of small and medium-sized enterprises and innovation and external mandates (Mediterranean and ACP States in particular). Over the past twenty years, successive enlargements, the erosion of France's comparative advantages and the decline of its linguistic and cultural influence have precipitated, as in the European Commission, the loss of an influence which had really started in the mid-1970s.
Parlamentarier für Europa – Die Vernetzung des Bundestags mit europäischen interparlamentarischen Körperschaften durch Doppelmandate (1950-1969/70
Authors: HÄHNEL Paul Lukas
Published: February 2021

The article examines inter-parliamentary institutions as a factor for interstate cooperation in Europe in the 1950s and 1960s. For this purpose, an analysis of the relationship between the parliamentary assembly of the European Communities, the Consultative Assembly of the Council of Europe and the Parliamentary Assembly of the Western European Union and their connections to the Bundestag through dual mandates is carried out. Based on the relevant literature, the article highlights formal and informal inter-organizational links as well as partly overlapping and competing competences between these inter-parliamentary institutions. By using the example of the Federal Republic of Germany, multiple connections between the Bundestag and the emerging European parliamentary level are shown. Finally, the article focuses on the disentanglement of the parliamentary levels in the 1970s.
Beneficiary Pays and Respect for Autonomy
Authors: Lindstad Sigurd ,   Department of Philosophy, Florida State University
Published: January 2021

This paper proposes that the “beneficiary pays principle” may be grounded in a brand of respect for autonomy. I first argue that on one understanding, such respect implies that as far as we are not morally required to make some sacrifice in service of some purpose, we each have (pro-tanto) legitimate authority to ourselves decide the purposes for which we should make sacrifices. I then argue that the problem with retaining benefits realized by imposed sacrifices, which the victim was not required to make in order to realize the benefits in question, is that doing so is disrespectful of the victim’s autonomy.

Published: February 2021

Making managerial decisions when choosing a variant of the technological chain for logging is complicated by the variety of natural and climatic conditions. The climatic features of the periods affect the productivity of technological machines and the cost of implementation. This research suggests using network planning to determine the technological chain of timber land development. The purpose of the research is construction of multi-purpose network models for planning the technological chain of logging operations in various production conditions of forestry enterprises operation. These models are aimed at making it possible to conduct calculations to increase the efficiency of labour, materials, funds, equipment distribution with the maximum reduction in the cost of logged products. As a result of the analysis of possible options for technological chains, several network models for the implementation of logging technological processes have been built.
DOS INTERPRETACIONES SOBRE LA ACTIVIDAD ANALÓGICA EN LA PSICOLOGÍA Y ONTOLOGÍA FENOMENOLÓGICA DE J-P. SARTRE: DISTINCIÓN MATERIAL O FUNCIÓN ANALÓGICA
Authors: Leiva Rodolfo
Published: February 2021

En el presente artículo presentaremos dos posibles enfoques sobre la actividad analógica de la conciencia en L’imaginaire de Jean-Paul Sartre: el primero, centrado en la composición ontológica del analogon, distinguirá el “analogon psíquico” del “analogon físico” y deducirá a partir de allí las dificultades y limitaciones del planteo sartreano y planteará a su vez los medios para dar respuesta a tales problemas. El segundo intentará explicar la función analógica de la conciencia imaginante como el resultado de un proceso de emancipación de la fenomenología de Husserl en la que la distinción material del analogon expresa el punto de partida de un desarrollo crítico que conducirá al abandono de la dimensión hylética del analogon a favor de la función analógica de la conciencia. Estas perspectivas nos brindarán un panorama de los límites legítimos de cada una, así como de la profundidad y el dinamismo del pensamiento sartreano.In this article we will present two possible approaches on the analogical activity of consciousness in L'imaginaire of Jean-Paul Sartre: the first one, focused on the ontological composition of the analogon, will distinguish the “psychological analogon” from “physical analogon” and will deduce the difficulties and limitations of Sartrean argument and the means to resolve them. The second one will try to explain the analogical function of imaginative consciousness as the result of a process of emancipation of Husserl's phenomenology in which the material distinction of the analogon expresses only the starting point of a critical development that will lead to the abandonment of the hyletic dimension of the analogon for the analogical function of consciousness. These perspectives will give us an overview of the legitimate limits of each one, as well as the depth and dynamism of Sartrean thought.
UN ANÁLISIS FENOMENOLÓGICO DE LA PROPIEDAD CONTRAPUESTO AL "NEW REALISM" DE MAURIZIO FERRARIS
Authors: Bueno Junquero Adrián
Published: February 2021

El presente ensayo compara un análisis fenomenológico de la propiedad con el nuevo realismo de Maurizio Ferraris. La comparación expone los límites de la perspectiva fenomenológica al mismo tiempo que también muestra los momentos estructurales de su modo de dación: (1) momento intuitivo; (2) momento de la solicitud; (3) momento del reconocimiento; (4) momento de la propiedad. Una vez expuesta la unidad de estos momentos, el ensayo pone de manifiesto cómo la perspectiva del nuevo realismo pensaría la propiedad a través de la nueva ontología del objeto, es decir, como un objeto social vinculado a un acto social. Las conclusiones exponen el carácter fenoménico de la propiedad como condición del análisis fenomenológico, en contraposición al planteamiento de Ferraris, donde la propiedad sería tratada como un objeto. No obstante, ambas perspectivas pensarían la propiedad como un acto vinculado al deseo de apropiación, lo que permite una inves-tigación fenomenológica de la voluntad.The present essay compares a phenomenological study of the property with the new realism of Maurizio Ferraris. The comparison shows the limits of the phenomenological perspective and simultaneously the structural moments of its mode of givenness: (1) the intuitive moment; (2) the moment of the request; (3) the moment of the admission; (4) the moment of the ownership. Once the unity of these moments is exposed, the essay shows how the perspective of the new realism would think the property through a new ontology of the object, that is, as a social object related to a social act. The conclusions expose the phenomenological character of the property as a condition of the phenomenological approach in contrast to the Ferrari’s proposal, where the property would be treated as an object. Nevertheless, both perspectives would think the property as an act related to the wish of appropriation, which allows the phenomenological investigation of the will.

El presente artículo tiene por objetivo analizar desde un punto de vista ontológico los retos económicos y existenciales que Europa afronta durante los últimos años, a consecuencia de la crisis económica y de la masiva oleada de refugiados derivada de los conflictos en el mundo Árabe. Cimentando nuestra argumentación en la interpretación de Martin Heidegger del ser humano como δεινόν, asombroso, tratamos de demostrar que el núcleo ontológico de la situación turbulenta que actualmente vivimos puede hallarse en el evento de la ausencia de hogar, en tanto que carencia de una morada propia en Europa. Por último, presentamos la política e ideológicamente convulsa matriz del esquema político europeo moderno, a fin de subrayar la relevancia de redefinir, por una parte, el significado de familiaridad y coexistencia para nosotros, los europeos, y, por otra, Europa en tanto que totalidad.The aim of this article is to analyse from an ontological point of view the challenges, economic and existential, that Europe has been facing the last years as a result of the economic crisis and the incoming human waves of the refugees as a result of the conflicts in the Arab world. Namely, founding our argumentation on the interpretation of the human being as δεινόν, uncanny, made by Martin Heidegger we would like to show that the ontological core of the turbulent situation we are currently living in can be found in the concept of homelessness as the lack of our abode in Europe. Finally, presenting the political and ideologically intense matrix of the modern European political scene we aim at highlighting the importance of redefining what homeliness and cobelonging mean to us, Europeans and Europe as a whole.
EL VALOR DE LA GUERRA Y LA PAZ EN EL PENSAMIENTO FENOMENOLÓGICO DE MAX SCHELER
Authors: Ramírez Patiño Marisol
Published: February 2021

El problema de la paz ha interesado y preocupado a la conciencia universal prácticamente desde sus inicios. No obstante, la historia que nos es conocida se caracteriza por una larga sucesión de conflictos armados que no han traído ni siquiera los atisbos indubitables de su consecución. Así, entre el ecuménico anhelo de la paz y la adversa realidad, preguntamos: ¿es la idea de la paz humanamente posible? Este ensayo aporta una respuesta a esta interrogante desde las reflexiones de Max Scheler (1874-1928). Los dos escritos que muestran con más detalle su postura ante esta problemática, Der Genius des Krieges und der Deustche Krieg (1915) y Die Idee des ewigen Friedens und der Pazifismus (1927), respectivamente, ofrecen elementos que podrían concretar la experiencia actual de la guerra, así como la posibilidad de un rotundo estado de paz en el mundo.The problem of peace has interested and concerned to the universal consciousness since its beginnings. However the known history is characterized by a large succession of armed conflicts that hasn’t even brought blinks of its uncontested triumph. Thus, between the ecumenical craving for peace and the opposite reality, we ask: Is it the idea of peace humanly possible? This essay tries to give an answer on this questions from the reflections of Max Scheler (1974-1928). Both writings that show with more detail his position to this problem, Der Genius des Krieges und der Deustche Krieg (1915) y Die Idee des ewigen Friedens und der Pazifismus (1927) respectively, they both offer elements that could grasp the actual experience of war, as well as the possibility of an absolute state of peace in the world.

La fenomenología husserliana es concebida desde el principio como un intento de superar la metafísica tradicional. El presente estudio intenta comprender el sentido y alcance de esta superación mediante un viaje al interior del proyecto filosófico de Husserl. En su itinerario intelectual dos conceptos son fundamentales: la reducción y la pregunta por el origen. En estas coordenadas la fenomenología es presentada como una filosofía que restituiría el sentido ori-ginario de la metafísica y de todo el proyecto científico.From the beginning Husserl’s Phenomenology is conceived as an attempt to overcome the traditional metaphysics. The present study tries to understand the meaning and scope of this overcoming by an incursion into the interior of the philosophical project of Husserl.

São limitadas as informações sobre a atividade residual de herbicidas aplicados no controle das soqueiras do algodoeiro e o seu potencial para afetar o desenvolvimento e a produtividade do milho semeado na safra seguinte. O objetivo desse trabalho foi identificar o efeito carryover promovido pela aplicação única e sequencial de herbicidas utilizados no controle das soqueiras do algodoeiro e estimar o intervalo de segurança entre o manejo químico da soqueira do algodoeiro e a semeadura do milho. Foram conduzidos simultaneamente dois experimentos em casa de vegetação, um para aplicação única e outro para aplicação sequencial dos tratamentos herbicidas. Os experimentos foram instalados em esquema fatorial 15 x 5, delineados em blocos casualizados com quatro repetições. O primeiro fator foi composto por tratamentos herbicidas e o segundo fator por cinco épocas de semeadura do milho após a aplicação (0, 30, 60, 90 e 120 dias). As parcelas experimentais foram compostas de vasos plásticos com capacidade para 3 dm3 preenchidos com solo de textura argilosa (470 g kg-1 de argila), seco e peneirado. Os herbicidas utilizados foram 2,4-D, glyphosate, saflufenacil, [imazapic+imazapyr], dicamba, fluroxypyr e sulfentrazone. Conclui-se que a aplicação sequencial da maioria dos tratamentos proporcionou um aumento na atividade residual dos herbicidas avaliados. Os tratamentos 2,4-D (1340 g ha-1), 2,4-D + glyphosate (1340 + 720 g ha-1) e 2,4-D + glyphosate + saflufenacil (1340 + 720 + 105 g ha-1) apresentaram os menores intervalos de segurança e foram aqueles que apresentaram o menor risco de afetar o milho semeado em sucessão, mesmo em aplicações sequenciais. Contudo, os tratamentos constituídos pela associação com herbicidas de maior atividade residual no solo como o dicamba, fluroxypyr, sulfentrazone e [imazapic+imazapyr], apresentaram maior potencial de carryover para a cultura do milho, sendo observado intervalo de segurança superior a 94 dias após a aplicação sequencial de 2,4-D + glyphosate + sulfentrazone.
Protesta y movilización en el Sacro Imperio: Hans Böhm y la marcha de Niklashausen

En la primavera de 1476 un tamborilero y pastor de ovejas llamado Hans Böhm tuvo una visión de la Virgen María en la pequeña localidad de Niklashausen que le llevó a predicar un discurso radicalmente crítico y contestatario. En este artículo analizaré a modo de microhistoria la marcha y la rebelión que desencadenó esta protesta en el pequeño valle del Tauber.

In the spring of 1476, a drummer and sheepherder called Hans Böhm had a vision of the Virgin Mary in the small town of Niklashausen that led him to preach a radically critical and contentious discourse against the local authorities. In this article, I will analyze through a microhistorical lens the march and rebellion that triggered this protest in the small Tauber valley.
Optbayesexpt: Sequential Bayesian Experiment Design for Adaptive
Measurements
Authors: McMichael Robert D. , Blakley Sean M. , Dushenko Sergey
Published: February 2021

Optbayesexpt is a public domain, open-source python package that provides adaptive
algorithms for efficient estimation/measurement of parameters in a model function.
Parameter estimation is the type of measurement one would conventionally tackle with a
sequence of data acquisition steps followed by fitting. The software is designed to
provide data-based control of experiments, effectively learning from incoming
measurement results and using that information to select future measurement settings
live and online as measurements progress. The settings are chosen to have the best
chances of improving the measurement results. With these methods optbayesexpt is
designed to increase the efficiency of a sequence of measurements, yielding better
results and/or lower cost. In a recent experiment, optbayesexpt yielded an order of
magnitude increase in speed for measurement of a few narrow peaks in a broad spectral
range.
Diminution du nombre de logements disponibles pour les ménages
et pression touristique : l’exemple de Barcelone
Authors: Sales-Favà Joan , Chevalier Paolo , López-Gay Antonio , Módenes Juan A.
Published: February 2021

Ces dernières années, le tourisme augmente de manière
exceptionnelle dans des villes européennes comme Barcelone. Simultanément à
l’accroissement du nombre de visiteurs et celui des nuitées, le nombre de
chambres disponibles dans l’hôtellerie traditionnelle progresse. Aussi, pour
diversifier l’offre, la quantité de logements à usage touristique a augmenté.
Cette forme d’hébergement touristique transforme progressivement le parc de
logements dans les quartiers centraux de la ville, changement qui pourrait
modifier la structure de la population résidente permanente. En effet, les
habitants et les touristes se font concurrence pour accéder à un même bien, le
logement. Des tensions émergent dans certains quartiers de Barcelone. Les
habitants dénoncent l’incompatibilité de ces deux usages. La pression
touristique serait la cause d’une diminution du nombre de logements disponibles.
Dans cet article, l’impact des logements à usage touristique sera analysé afin
de savoir s’il existe une relation entre l’augmentation du nombre de logement à
usage touristique et l’évolution du nombre de ménages résidents permanents. Une
comparaison géographique du nombre de ménages résidents permanents, du stock de
logements et du nombre de logements à usage touristique a été réalisée pour les
233 aires statistiques basiques (AEB) de Barcelone.
La certification qualité en milieu rural
comme moteur de viabilité du tourisme
Authors: de la Ballina Francisco Javier , Valdés Luis , Del Valle Eduardo
Published: February 2021

L’un des piliers principaux du tourisme rural durable est la
viabilité économique de ses entreprises. Les normes de qualité rurale peuvent
être un instrument intéressant pour l’évaluer, car elles permettent de mesurer
les effets positifs directs et indirects de la durabilité, dans le but
d’améliorer la professionnalisation et la taille des entreprises rurales, de
mettre en valeur l’architecture et la culture traditionnelles, d’accroître la
valeur économique de segments de tourisme de petite taille. Ainsi, l’intérêt des
entreprises rurales pour obtenir des marques de qualité dépend des avantages
économiques qu’elles peuvent leur apporter, au moins pour supporter initialement
l’investissement et les coûts de sa mise en œuvre. Nous avons effectué une
recherche empirique à partir d’une base de données des résultats économiques
obtenus par un ensemble d’hôtels ruraux dans une région spécifique de l’Espagne
qui ont adopté une norme de qualité rurale. Les résultats fournissent des
preuves de l’existence d’une relation directe entre la norme de qualité et les
résultats économiques du tourisme rural, principalement grâce à l’effet positif
sur le prix des chambres. C’est un enjeu fondamental pour réaliser des
investissements de qualité dans les hôtels ruraux.

Faire bloc contre le bacille rouge : la presse canadienne face à la Commune de Paris de 1871*
Authors: Bargain-Villéger Alban
Published: February 2021

Cet article analyse la couverture de la Commune de Paris dans la presse canadienne. La Commune, un gouvernement insurrectionnel d’inspiration simultanément républicaine et socialiste, n’a duré que deux mois, du 18 mars au 28 mai 1871. Réprimée dans le sang par le gouvernement officiel, cette révolution marque un moment clé de l’histoire de la gauche et, plus précisément du socialisme français et international.

En effet, bien qu’éphémère, cet épisode a eu un certain impact, non seulement en France, mais aussi dans d’autres pays. Au Canada, la Commune a joué un rôle dans l’élaboration d’une base morale consensuelle en vue de renforcer le projet confédéral. Bien que des Canadiens se soient certainement reconnus dans les idées de la Commune, la plupart des journaux se rejoignent sur un point : le régime alors en place à Paris est une aberration.

Ainsi, cette étude s’inscrit dans le sillage d’Ian McKay, qui soutient que le Canada a vécu une « révolution libérale » entre les années 1830 et 1940. Pour ce qui est de la Commune, l’idéologie libérale a joué un rôle majeur dans la conciliation des intérêts divers et souvent divergents impliqués dans le projet de construction nationale. De fait, que l’on analyse le sujet du point de vue religieux, social ou du genre, les journaux canadiens condamnent unanimement un régime qu’ils voient comme amoral, contre-productif et barbare, et donc contraire à l’esprit de la construction nationale.
Romance de la Negra Rubia de Gabriela Cabezón Cámara: entre la autobiografía tránsfuga y el autorretrato de un sujeto cínico
Authors: Flisek Agnieszka , Moszczyńska-Dürst Katarzyna
Published: February 2021

Romance de la Negra Rubia (2014) de Gabriela Cabezón Cámara es una autobiografía ficcional de Gabi, una paria que con su cara quemada concebida como símbolo de protesta popular consigue llegar a las cumbres del poder. Nuestro propósito es examinar las diferentes modulaciones de la voz narrativa de la novela, una voz que se desliza rápidamente de la compasión o la autocompasión en la burla, el sarcasmo y la parodia para desenmascarar la lucha popular como una performance, la experiencia límite del dolor y la muerte como una instalación y una puesta en escena mediática, la contracultura y la estética transgresora como arte servil a la hegemonía de la mercantilización, el amor como un constructo cultural patriarcal y un producto del “consumo de la utopía romántica”. Observaremos la manera en que este yo, que privilegia la ironía como modalidad expresiva por su radical antifundamentalismo epistemológico y axiológico, se aleja de la autobiografía tránsfuga modélica y construye el autorretrato de un sujeto que asume la máscara cínica para desmontar el espectáculo cínico de la sociedad contemporánea.
