AIM: To evaluate the effect of vitamin B12 deficiency anemia (BDA) on peripapillary retinal nerve fiber layer thickness (RNFLT) using spectral domain optical coherence tomography (SD-OCT), and to determine any correlation arising thereof.
METHODS: In this cross-sectional observational study, 99 eyes of 50 BDA patients of age 18-65y were compared with 100 eyes of 50 healthy control subjects. All subjects underwent comprehensive clinical, ophthalmic, and hematological evaluation, followed by peripapillary RNFLT assessment using SD-OCT.
RESULTS: The mean total, inferior, nasal, and temporal RNFLT were significantly lower in BDA group as compared to control group (P<0.05). The mean total, inferior and nasal RNFLT correlated significantly (P<0.05) with serum Hb%, B12 and mean corpuscular volume (MCV) level (r=0.310, 0.435, -0.386 for total; r=0.932, 0.481, -0.513 for inferior; r=0.344, 0.254, -0.233 for nasal; respectively), while temporal and superior RNFLT quadrant did not show any correlation with any of the hematological parameters (r=0.144, 0.167, -0.096; r=0.111, 0.070, -0.099; respectively). The mean total RNFLT showed progressive thinning at par with the progression of anemia, except in very severe BDA, where an inverse relationship was documented.
CONCLUSION: The mean total, inferior, nasal, and temporal peripapillary RNFLT was significantly thinner in BDA patients. Peripapillary RNFLT thinning seemed to proceed at par with the progression of severity of anemia, except in very sever grade. Early assessment of peripapillary RNFLT may be crucial in BDA patients to prevent potential blinding sequelae. Peripapillary RNFLT thinning in BDA patients should be considered in the differential diagnosis of other non-glaucomatous optic neuropathies, as well.
Novel Simplified Approach for the Thermal Characterisation of Triple Tube Heat Exchangers

Published: August 2021

To assess the performance of triple tube heat exchangers, it is not possible to apply the traditional methods (e.g., Wilson plot method) because they can be only applied to the classical shell-in-tube configuration that can be easily modelled by the logarithmic mean temperature difference approach. Therefore, to overcome this limitation, some new methodologies have been proposed in the literature and, among them, a promising tool is represented by the parameter estimation procedure. Parameter estimation procedure is a powerful technique already adopted in many engineering applications. However, this procedure requires, for the application investigated in the present study, a detailed numerical model of the triple tube heat exchanger and the measurement of the temperature of the fluids in each tube at inlet and outlet sections. These elements make its application feasible only in well-equipped research labs, limiting its massive employment in industrial facilities. In this paper, a novel parameter estimation procedure to characterize the thermal behavior of the triple concentric-tube heat exchanger is proposed. This approach is based on a simple model of the exchanger and it requires to measure the fluid temperature only in four sections. The simplified proposed procedure is numerically validated and compared to the full one.
Microclimatic and Ventilation Conditions in Existing Healthcare Facilities. A Study in the Waiting Room-Testing Centre of a Florentine Historic Hospital
Authors: Balocco Carla , Petrone Gerardo Lorenzo
Published: August 2021

The pandemic COVID-19 era we are experiencing has changed our way of seeing, thinking and designing indoor and outdoor environments and, above all, plant systems and building-plant management. Energy environmental sustainability is a common fundamental target for buildings and plant systems, but health protection and prevention are the priority issues for the basis of any retrofitting and refurbishment operation. This question becomes even more complex if the building is historic and used for hospital or for healthcare facilities. In this research we propose a methodological approach based on the combination of physical-real and “virtual”, i.e. measured and simulated information. The proposed method can be a useful tool for setting up continuous monitoring systems for microclimatic and ventilation conditions, user influx/presence and behaviour, real operation (on demand) of the plants and control/regulation system adjustment. Results show the importance of drawing up useful guidelines for training health workers and people/patient subjects, aiming at conscious interaction for health and wellbeing protection, but also better indoor environment management. This is particularly important for healthcare environments such as the one studied.

In this paper, the energy and environmental impacts of a passive retrofit action, involving the installation, on an office building, of a second-skin system with the external layer made of a PVC-coated polyester fabric, were evaluated in terms of primary energy saving and carbon dioxide equivalent emissions. The primary energy consumption and the carbon dioxide equivalent emissions associated with the considered case studies were evaluated through the dynamic simulation software TRNSYS, across a whole year. The study was carried out considering five cities (Athens, Barcelona, Lisbon, Marseille and Naples) in five different countries in southern Europe upon varying the orientation of the two main façades of building (north-south and east-west orientation were considered). The office building was modeled in detail considering different construction characteristics upon varying the country. The simulation results highlight that the best results in terms of PES (equal to 22.4%) in Naples, while the best results in terms of CO2 (equal to 32.0 MgCO2,eq) were obtained when the building is located in Athens. In addition, the adoption of the proposed passive lightweight retrofit solution allowed the reduction of both cooling and thermal yearly energy demand up to 57.7% (Marseille) and 17.8% (Barcelona), respectively.
El papel de las Fuerzas Militares estatales en la Cátedra de Paz y la seguridad: una mirada desde el departamento de Cundinamarca
Authors: Farfán Moreno William , Bravo Guerra Luis Wuilliam
Published: August 2021

Uno de los objetivos del Acuerdo Final de paz de Colombia (2016) fue fomentar conocimientos y competencias sobre el territorio, la cultura, el contexto económico y social y la memoria histórica mediante la Cátedra de Paz. Cuando se plantean los temas relacionados con la memoria histórica y la paz en la escuela, surge la inquietud sobre el papel de las Fuerzas Militares (FFMM) estatales en la cátedra. La pregunta surge porque, en la medida en que las FFMM, en el nivel institucional, son actores armados y, desde la subjetividad de sus miembros, algunos son víctimas del conflicto armado, también deben ser constructores de paz y aportar a la cátedra. Por tanto, el propósito del presente artículo es interpretar y analizar las percepciones que de las FFMM se tienen en la escuela, sobre la Cátedra de Paz, mediante el enfoque cualitativo, utilizando el método de análisis de contenido de los discursos de los participantes en los grupos focales (directivos, docentes y padres de familia de escuelas privadas y oficiales de Cundinamarca, Colombia), con el propósito de generar recomendaciones tanto para la cátedra como para la institución militar. Entre los resultados de la investigación, se encuentra que la percepción sobre la labor de las FFMM dentro de los procesos de enseñanza-aprendizaje en la Cátedra de Paz es que, a partir de la firma del Acuerdo Final y la implementación de la cátedra, se están repensando como actores, no solo como garantes del orden, sino como constructores de paz. Así también que el nuevo contexto obliga a resignificar el papel de las FFMM como actores para la paz.
Utilising Building Information Models in Facility Maintenance and Operations
Authors: HALMETOJA Esa , LEPKOVA Natalija
Published: August 2021

Utilising the digital capital of buildings, including building information modelling (BIM), is crucial for building owners from the perspective of high-level maintenance. This case study concerns a company in which building information models are received as files complying with the Industry Foundation Classes (IFC) standard. An analysis of the information content of the IFC files was performed to investigate whether the files, which were generated in a construction project using traditional procedures, contained relevant information for maintenance. The critical needs were evaluated based on the aspects highlighted in an online survey. As a result, essential content requirements for BIM are presented for facility maintenance and operations (FMO). It has been shown that existing building information models cannot close the information gap from a facility maintenance perspective. Still, they have significant potential due to their ability to contain technical information and provide a graphical representation. With information exchange requirements (IERs), a great deal of progress could be made by utilising BIM for FMO. A property service company’s capabilities must also be evolved before the benefits of digital capital can be reaped. This paper provides insights for developing the information content of computerised maintenance management systems (CMMS) and demonstrates the crucial need to harmonise them using BIM. Finally, as a new use case for BIM, this paper presents an operations and maintenance model (OMM).

An Opuscule on Method, or how Philosophers Mark out Textually their Methodological Stance (a Text Following up a Text)
Authors: Svatko Yuriy
Published: August 2021

The present paper is a practical supplement to an earlier theoretical work by the author, published in a preceding issue, on methodological foundations of the European philosophizing in the aspect of sophical synthesis. Building upon understanding of general philosophical methodologies (methodological attitudes) and their ‘epochal’ implementations as presented there, the author makes use of a cross-cutting example, to show ‘zones of responsibility’ and onto-gnoseo-epistemological limits for every mentioned ‘way towards the thing.’ Six marker packages (by the number of methodologies and variants of sophical viz. life-knowledge synthesis) should be of special professional interest as proposed by the author to identify methodological attitudes and ‘edge’ cases ranging from Antiquity to nowadays. Validity of each and all of these packages has been illustrated with proper textual material, i. e. fragments from essays by renowned European philosophers.In § 1, the naturalistic methodological attitude is considered, as focused on the proper vital aspect of sophical synthesis; its characteristic reliance on experience, fact, belief, opinion, and authority, and thereby on the rhetorical aspect of philosophizing, is explained.In § 2, the phenomenological methodological attitude is considered, as focused on the proper knowledge aspect of sophical synthesis; its characteristic reliance on knowledge and sense beyond any non-essential per se factual ways things are given, is explained.In § 3, the transcendental methodological attitude is considered, as focused on the synthesis of knowledge and life by means of knowledge in the aspect of logos of the logos per se; its characteristic reliance on sense being a sense in the making, and on fact as the bearer of a sense, with their integration in a common logical-conceptual thing structure, is explained.In § 4, the dialectic methodological attitude is considered, as focused on the synthesis of knowledge and life by means of knowledge in the aspect of logos of the eidos; its characteristic reliance on intelligent thing as a unit of sense and a product of senseful self-development wherein not only the thing is posited, but the entire otherness as defined by it as well, is explained.In § 5, the mythological methodological attitude is considered, as focused on the synthesis of knowledge and life in the aspect of their integral arrangement as vivid mind; its characteristic reliance on intelligent thing as a real and self-evident in its unicity live being, is explained.In § 6, the hermeneutical (= onomatological and overall symbolic) methodological attitude, as focused on the synthesis of knowledge and life in the aspect of its naming as an intelligent expression of thing for the other; its characteristic reliance on the name and text as a full expression of sense and a full knowledge of fact being revealed in the truth of thing, is explained.
Application of Justice by Court in Solution of Conflicts of Legal Interests
Authors:   Head of the Department of Civil Procedure Law of the Ural Branch of the Russian State University of Justice PhD (Law), Associate Professor, Burmistrova Svetlana A.
Published: August 2021

Despite the widespread consolidation of the principle of justice in normative acts, its law enforcement significance continues to be debatable, while the analysis of judicial practice shows that courts often use the noted moral and ethical principle as a basis for resolving conflicts of substantive, procedural interests, including in cases where such conflicts are based on conflicting principles of law. It is significant that the free operation of the category of justice is peculiar to the verification instances, while for the first and initial verification instances the content of the principle of justice and its application to the settlement of disputes continues to be obscure. In order to solve this problem, the article attempts to determine the content of justice and derive a formula for its practical use.

The article reveals the main directions and trends in the development of the civil process, in particular, the tendency to bring together not only civil and arbitration processes, but also civil and administrative processes. Demonstrates the desire of the legislator to unify civil, arbitration and administrative proceedings. The realized ideas of unification of the civil process are analyzed, such as replacing the institution of jurisdiction with the institution of jurisdiction, reforming simplified procedures for considering cases, introducing the institution of conciliation procedures, changing the procedure for calculating procedural terms, changing the procedure for considering challenging a judge, and other issues that accompany reforming the civil process.
Glocalization Practices of Supermarket Chains. Case Study: Food Retailers in Romania
Authors:   Politehnica University of Timisoara, Palea Adina
Published: August 2021

Glocalization has continuously gained popularity over the past 20 years. The rise of nationalism and other trends in political radicalization have strengthen the need for retailers to find local solutions to their globally distributed products. In some cases, the adaptation has happened smoothly and naturally, in other situations it was imposed by the local judicial context. The paper focuses on European supermarket chains, like Kaufland, Lidl or Penny, giving special attention to their glocalization strategies used in Romania. The research has revealed that the retailers have become quite versatile and that they are currently developing products tailored to satisfy Romanians’ expectations regarding traditional tastes, recipes, and design.

We are constantly evolving, society is modernizing and most are beginning to accept change, but nevertheless we still strongly have a model to relate to the two genders (male and female) well inoculated within our culture and way of thinking. The volume ”Bărbatul şi femeia : imaginea unei polemici cu privire la echitatea de gen” [The man and the woman. The image of a controversy regarding gender equity], published by Lumen Publishing House from Iași, Romania, in 2017, manages, under the guidance of professor Iulian Apostu and Cristina Georgiana Petrescu, to analyze a lot of subjects that are still very topical and outline both genres socially, psychologically and scientifically. The volume contains an introduction, four chapters, conclusions, a references list and an appendix. The themes of this book are focused on both genres and how they coexist or come into conflict. The introduction reveals the intention and motivation of the study in broad terms, such as the desire to observe how men relate to women's emancipation.

The particular extent of the phenomenon of crime in modern society, the increasingly frequent violations of values that interest the international community as a whole or target the interests of a large number of states, as well as the emergence of organised crime which transcends national borders through criminal networks operating in the territory of several states, are the basis for the establishment and development of international criminal law as an expression of the coordination of efforts to ban and repress antisocial acts detrimental to the legality and progress of the entire contemporary human society. Attempts to define international criminal law have been made over the years, but it should be pointed out that international criminal law is a relatively new branch of law and is still in the process of being codified, i.e. through international agreements in the form of conventions or treaties establishing general rules with binding legal force. Its content is developing day by day, and is becoming more and more deeply embedded in the legal consciousness of nations, which is only to be expected if we consider the dynamics of international society in recent times. Its importance is constantly growing as the development of military technology, the use of chemical and bacteriological weapons and the threat of the use of atomic weapons require the legal protection of international security and peace.

The problem of providing lifelong learning opportunities at the present stage of global community development remains relevant and is a top-priority agenda for practically all civilized countries. Positive experience in organizing professional training of preschool teachers in European countries requires that perspective trends in the modernization of future preschool teachers’ professional training should be specified following European standards of teacher education and the most significant achievements of higher education, its peculiarities and specifics should be preserved. Conceptual principles, peculiarities of historical development and key trends in the system of professional teacher education in Germany, France and the UK have been analyzed and determined; professional profiles, professional competency profiles and qualification requirements have been characterized; both national specific and general common trends in development of preschool teachers’ professional training in European countries have been outlined. The development of professional standards for teacher education in European countries contributes to specifying and developing professional profiles of preschool teachers in Europe that are rather diverse and determine the multifacetedness and multifunctionality of professional training. The main trends in education policy and qualification requirements for professional training of preschool teachers in European countries include: providing public sector specialists with initial training; adjusting consecutive education to the provisions of the Bologna Declaration; ensuring continuing professional development of specialists involved in educational activities in preschool institutions; implementing the European conception of professional training with the use of competency-based approach.

Chronic tonsillitis (CT) is an urgent problem in modern otorhinolaryngology. According to various authors, the incidence of this pathology is 5–18%. Complications from other organs and systems that occur on the background of CT significantly worsen the quality of life and may cause disability of the patient and can cause the death of patients. A radical method of treating this pathology is surgery (tonsillectomy). The main complication during surgery is pharyngeal bleeding, which can develop both after the operation and in the postoperative period. The article presents data on the use of tranexamic acid (TC) to prevent pharyngeal bleeding and reduce pain in the throat in patients in the postoperative period after tonsillectomy. The study included 160 people, divided into 4 groups of 40 people each, depending on the method used to remove the palatine tonsils. The use of TC in the postoperative period helps to reduce bleeding after tonsillectomy, as well as reduce pain in the throat.

Foreign bodies of the respiratory tract and esophagus remain one of the pressing problems in medicine, which is associated with the possibility of developing complications that can end in death. We present our clinical observation that demonstrates the long-term presence of a large foreign body fixed in the area of the pharyngeal narrowing of the esophagus and extending into the larynx and the vestibule of the larynx. Patient T., 57 years old, went to the emergency department of the Karachay-Cherkessia Republican Clinical Hospital with complaints of severe sore throat, inability to swallow, excessive salivation, increased body temperature to 37,5 °C, difficulty breathing, mixed shortness of breath, which persist for 3 days. The examination revealed: the epiglottis is mobile, the mucous membrane of the larynx is hyperemic, edematous, with an abundance of saliva, at the level of the vestibular part of the larynx, in the area of the arytenoid cartilage and aryepiglottic folds, an irregular shape was visualized, with smooth edges, a thin, hard whitish plate. Computed tomography of the cervical spine: in the esophagus, at the level of C4-C5 vertebrae, a foreign body with a metallic density of +2900 hU units, elongated, irregular shape, measuring 2.2 by 3.3 cm, with perifocal air bubbles is determined. A preliminary diagnosis was made: Foreign body of the esophagus, laryngopharynx with a spread to the vestibule of the larynx. 3 days after the retention of the foreign body under intubation anesthesia, it is captured using forceps with serrated cups and removed during direct laryngoscopy. There were no complications during the manipulation. The combination of X-ray and endoscopic examinations with the help of innovative medical and diagnostic equipment made it possible to establish a diagnosis in a short time, choose the most effective treatment tactics and remove a foreign body through natural pathways.

Deterioration in speech intelligibility, the most common complaint of people with hearing loss, leads to social isolation and dramatically reduces the quality of life. The correction of peripheral hearing loss by hearing aid fitting does not always solve this problem in patients with chronic sensorineural hearing loss (SNHL). That is why in the process of audiological examination of patients with complaints of hearing loss, it is necessary to include methods of speech audiometry, which make it possible to comprehensively assess the functioning of the auditory system. The aim of the study: assessment of speech intelligibility in patients of different ages with SNHL. 94 people from 20 to 74 years of age were examined: 54 patients with SNHL (14 young and 40 elderly) and 40 people with normal hearing thresholds (20 young and 20 elderly). Besides the standard audiological examination, speech audiometry testing was conducted: evaluation of monosyllabic words intelligibility in quiet, binaural rapidly alternating speech test, dichotic digits test, Russian matrix sentence test (RuMatrix). Results: Speech intelligibility in elderly patients with SNHL was shown to be significantly worse than in young patients with a similar degree of hearing loss. The RuMatrix test in noise was proved to be the most sensitive test for comprehensive evaluation of the hearing system functioning.

Published: August 2021

Se presenta el análisis de la visión regional extraída de los documentos de planeación (Plan de Ordenamiento Territorial –POT–) de Bogotá y algunos municipios de su área de influencia metropolitana. Así mismo, se aporta conocimiento empírico a los interesados en el seguimiento y evaluación de estos planes.La primer parte del artículo muestra una síntesis del desarrollo histórico del territorio colombiano, con el objeto de señalar que la conformación de las ciudades y áreas metropolitanas ha estado ligada a la transformación histórica del espacio por parte de la sociedad. La segunda presenta algunos indicadores que dan cuenta del crecimiento urbano continuo de Bogotá y de la consolidación del fenómeno de metropolización, además, muestra diferentes modelos de explicación de la jerarquía urbana colombiana, los cuales coinciden en señalar a Bogotá como el principal centro urbano del país que cumple la función de organizador y dinamizador del sistema de ciudades y,a su vez, de la región metropolitana circundante. La tercera parte presenta el análisis de la visión regional de los POT de Bogotá y de una muestra de municipios del área de influencia metropolitana. Para ello se consideraron aspectos como la visión, objetivos, formulación, estrategias e instrumentos y se identificaron ideas concretas acerca de la concepción y proyección de las relaciones entre cada municipio y Bogotá. Finalmente, se concluye que entre el marco de referencia para formular los POT de los municipios mencionados y la visión regional planteada en ellos no existe cohesión espacial ni temporal. Por tanto, los procesos de planificación regional en la zona metropolitana de Bogotá cuentan con un gran limitante instrumental.

Aporta elementos pertinentes para abordar los estudios multitemporales de la transformación ambiental desde perspectivas holísticas, que implican lecturas polisémicas de aspectos biofísicos, sociales, históricos y culturales aportados por disciplinas diversas. Los “hechos” espaciales,conceptualizados como cargados de historicidad y connotaciones ordenadoras, son caracterizados por múltiples formas discursivas y condicionamientos ideológicos desde los paradigmas dominantes, y son implementados mediante prácticas homogeneizantes de adoctrinamiento,apropiación, aculturación, educación y desarrollo, que implican desconocimiento de formas tradicionales de adaptación/adecuaciónsocioambientales y generan nuevas espacialidades. Se propone el paisaje como categoría integradora que expresa las herencias de las relaciones dialécticas cultura-naturaleza.
Análisis geográfico de problemas ambientales urbanos. Caso: geocorredor río Consota, municipio de Pereira (Risaralda)
Authors: Rivera  Pabón Jorge Andrés
Published: August 2021

Se expone una propuesta de análisis de problemas ambientales urbanos desde la perspectiva geográfica, para tal fin se toma como espacio objeto de estudio el geocorredor del río Consota, en el municipio de Pereira. El análisis busca reconocer los factores y relaciones que han incidido en la dinámica ambiental resultante de la territorialización y ocupación espacial de asentamientos humanos. De esta forma, se incorporan las causas sociales, económicas, políticas, culturales y biofísicas determinantes en la transformación y degradación ambiental. Igualmente, el análisis posibilita superar la gestión ambiental, restringida tradicionalmente a propuestas desde enfoquesingenieriles (civil, sanitaria, ambiental) y de la arquitectura.
Experiencias de la aplicación de las plusvalías municipales en Colombia Municipal plus Value Application’s Experiences in Colombia
Authors: Silva Herrera Jaime
Published: August 2021

Los municipios desarrollan una amplia gama de políticas fiscales o regulatorias inspiradas en la idea de que el incremento en el valor de la tierra puede ser utilizado en beneficio de la comunidad, por medio de la aplicación del efecto plusvalía municipal. Este artículo presenta, en su primera parte, una cortareseña de los instrumentos de captura de plusvalías  desarrollados en Colombia, en la segunda, el doble juego en el que incurre la participación en plusvalía, y en la tercera, los pasos que se deben seguir para conseguir el objetivo final.
The concept of the ideal form of the Russian state: problems and prospects
Authors: Lapaeva Angelina V.
Published: August 2021

We present the search for an optimal model of the Russian state through the prism of idealism. We doctrinally justify that the ideal form of the state is a construction that can be created theoretically and that can be approached, as it is gradually developed. In the modern sense, the ideal of state is already expressed in the Constitution of the Russian Federation – it is a democratic, legal, social state. We establish that the political and legal reform carried out in Russia has shown that the effectiveness of the country’s development depends on the importance of constitutional norms, the renewed role of the state, and the assertion and protection of human and civil rights and freedoms. We propose arguments indicating that modern Russia can be con-sidered a mixed (parliamentary-presidential) republic, an asymmetric and constitutional federation with a national-territorial character and democratic political regime. We investigate two main approaches to the definition of the ideal form of the state in modern Russia: firstly, a limited monarchy, a fed-eration with democracy elements (based on the historical and cultural fea-tures of the development of the state), and secondly, the existing and pro-claimed form of the state in the Constitution of the Russian Federation is considered, with an amendment to the challenges of the time. We conclude that the modern development of Russia, taking into account international standards, should move in the direction of the ideals already proclaimed in the Constitution of the Russian Federation with a mandatory focus on cul-tural, traditional and historical features of development.

Generation and Mitigation of Conducted Electromagnetic Interference in Power Converters – A Big Picture
Authors: de Beer Arnold
Published: August 2021

This article is a big picture of how electrical noise or conducted Electromagnetic Interference (EMI) is generated and mitigated in power converters. It gives an overview of what EMI in power converters is – from generation through to conduction and mitigation. It is meant to cover the complete subject as a summary so that the reader will have an outline of how to control conducted EMI by design (where possible) and how to mitigate by filtering. A clear distinction is made between Differential Mode (DM) and Common Mode (CM) EMI generation and mitigation. By using a boost converter as an example the trade-offs for DM noise control are discussed. It is shown how CM EMI is generated in a boost converter using the concept of the “Imbalance Difference Model” (IDM). Practical measurements for an in-line power filter is given showing the effect of the filter on the total EMI of a boost converter. Measurements for the CM current produced due to the imbalance difference for different values of the boost conductor are also shown. The main contribution of this study is linking CM noise generation to DM EMI. It is shown that CM noise is a direct consequence of DM noise (although circuit imbalance and coupling to a common ground also play a role). This paper will be useful to designers seeking the “bigger picture” of how EMI is generated in power converters and what can be done to mitigate the noise.
The Systematic Risk at the Crisis - A Multifractal Non-uniform Wavelet Systematic Risk Estimation
Authors: Sarraj Mounir , BEN MABROUK ANOUAR
Published: August 2021

The Capital Asset Pricing Model is a widely applied model to describe risky markets and to deduce their systematic risk. Its estimation, therefore, remains an important task in Econo-financial studies. Empirically, it focuses on the impact of return interval on the betas. Existing studies somehow turn around the same idea of measuring the value of the beta according to the uniform intervals of time during a fixed period. However, it is noticed easily, and especially in the last decade that many factors such as socio-political, and Econo-environmental ones have led to a perturbation in the timeline of the worldwide development, and especially in countries and regions having political changes. This led us to introduce a new idea of risk estimation taking into account the non-uniform changes in markets by introducing a non-uniform wavelet analysis. We aim to explain the Econo-political situation of Arab spring countries and the effect of the revolutions on the market beta. The main novelty is firstly the construction of a dynamic backward-forward model for missing data, and next the application of random non-uniform wavelets. The proposed procedure will be acted empirically on a sample corresponding to TUNINDEX stock as a representative index of the Tunisian market actively traded over the period January 14, 2016, to January 13, 2021. The chosen 5-years period is important as it constitutes the first 5-years-after the revolution and depends strongly on the Socio-Econo-political stability in the revolutionary countries.

Eufemismos numéricos y conceptuales del paro español: cifras, fuentes y perfiles formativos
Authors: Amber Diana
Published: August 2021

España se enfrenta a una alta cifra de desempleo que aún no ha recuperado los valores previos a la crisis económica. Sin embargo, las cifras no muestran todo el entramado de precariedad laboral que afecta a la sociedad española. Este trabajo parte de la concreción de la terminología usada en la medición del paro para estudiar la realidad referida al desempleo y a la precariedad laboral a través del análisis de estadísticas oficiales, descubriendo vacíos de información y silencios que suavizan los datos. Como estrategia metodológica se utiliza el análisis secundario de los informes de empleo de las fuentes oficiales españolas. Los resultados muestran cómo las diferentes conceptualizaciones intervienen en las cifras oficiales. Se ofrecen pistas para una interpretación más cercana a la realidad y se aterriza en la concreción del perfil formativo de la población desempleada. Se concluye que las cifras oficiales no reflejan con exactitud la vulnerabilidad social, obviando parte de la población en situación de riesgo, y que la formación ayuda, pero no es suficiente para ofrecer una respuesta absoluta al desempleo.
