The article summarizes the experience of Latin American countries in the field of transforming land relations from the point of view of social justice, forming the necessary space for the livelihood of peasants, ensuring their economic sovereignty and so on. It has been proved that free access to the land resources and control over them largely determine the overall potential of the development of rural areas and the social development of the country as a whole. Studies have revealed persistent trends towards biased land distribution in the Global South and over-concentration in the hands of dominant groups and large agricultural enterprises. It has a strong destructive effect on the overall development of the countries in the region and is reflected in unequal spatial development, systematic infringement of the rights of peasants, limiting employment growth, spreading poverty, destruction of social cohesion, destabilization of food systems at the local, national and global levels, emergence of armed conflicts, etc. The general threats of changes in land tenure and use in Ukraine related to the tendency to redistribute land resources in favor of the corporate sector, land over-concentration and landlessness of peasants are outlined; a number of factors contributing to the unbalanced distribution of land were identified, and the necessity of including the lessons of Latin American countries in the future social development of Ukraine, in the long term is substantiated.

Authors:   Institute of Forecasting and Macroeconomic Research under the Ministry of Economic Development and Poverty Reduction of the Republic of Uzbekistan, Mukhsimova Dilafruz
Published: February 2021

The article is devoted to the assessment of the impact of the development of manufacturing on economic growth in developing countries, in particular, the Republic of Uzbekistan. Conclusions for Uzbekistan take into account the peculiarities of the implementation of the Program for Localization of the Production of Finished Products, Components and Materials. To perform the estimates, a regression model was constructed to determine the impact of the factors of sustainable economic growth on per capita GDP (in US dollars of 2010), which indicator is used in the model as a dependent variable characterizing sustainable development. Factors of economic growth are substantiated with the use of well-known theoretical approaches and empirical data. The article presents a cross-country analysis of economic growth indicators in developing countries, which allowed to form a sufficient sample of data for estimates. The article evaluates the impact of the diversification factor on economic growth indicators, analyzes the relationship between the indicators of processing industry development and economic growth. The connection between the volatility of economic growth and the development of the processing industry is demonstrated, as well as a comparative analysis of different types of economic diversification in the developing countries selected for this study. Using correlation and regression analysis, the impact on economic growth of such factors as R&D expenditures, human capital, trade openness, the share of manufacturing in GDP, and employment in industry was analyzed in detail. Based on the author's study of the impact of these factors on economic development, the recommendations have been developed for developing countries, including Uzbekistan.

APPLICATION OF THE SYSTEMIC ANALYSIS FOR SOLVING THE PROBLEMS OF DEPENDENT EVENTS IN AGRICULTURAL LANDS - CHARACTERISTICS AND METHODOLOGY
Authors: Velkovski Valeri
Published: February 2021

Systemic analysis for the first time provides a generalized problem-solving methodology based on the system concept.
By its nature, the problem-solving function is close to the highest levels of functional representation of human activity.
Therefore, this function and its serving methodology are most integrative and include all the private functions required for its implementation.
Systemic analysis, such as problem-solving methodology, claims to play the role of unifying all the necessary methods, knowledge and action to solve problems.
This is what determines his attitude to such areas as operations research, theory of statistical decisions, decision theory, organization theory, and others.
For the implementation of management functions, the methods of the search and discovery theory, statistical methods, factor analysis, experimental theories, methods of study of the operations, methods of forecasting and others can be used.
The assessment of the ratio of system analysis and its related disciplines is based on the contribution of the individual discipline in the methodology for solving the problem.
The main content of the system analysis is not in the formal mathematical apparatus describing the systems and the problem solving and it is not in the special mathematical methods but in the conceptual apparatus, its ideas, approach and formulations.
Systemic analysis defines the base nomenclature of the functions that need to be implemented to solve the problem, that is to say, it defines the structure of the process performed by the organization as opposed to the traditional approach to the organization that determines its administrative structure.
A / Types of problems
A problem is called the situation, which is characterized by the difference between the required (desired) output and the existing outcome.
Exit is necessary if it is absent threatens the existence and development of the system.
Existing output is provided by the existing system.
The desired output is achieved by the desired system. The problem may be to prevent a reduction in output or increase. The condition of the problem is set by the existing system (the "known").
The requirement - this is the desired system. The solution to the problem is what fills the difference between the existing and the desired system.
The system that fills this difference is the object of construction and is called a solution to the problem.
Problems can be manifested by symptoms. The systematic manifestation of symptoms is a tendency.
Detecting the problem is a result of identifying the symptoms.
Identification is possible provided that the desired behavior of the system is known. Once the problem has been identified, it is necessary to predict its development and to assess the timeliness of the decision, that is to say, what will be the state of the system for an unresolved problem.

Published: February 2021

The Wilms’ tumour gene (WT1) has previously been described as an oncogene in several neoplasms of humans, including melanoma, and its expression increases cancer cell proliferation. Recent reports associate the expression of the PPARβ/δ gene (peroxisome proliferator-activated receptor beta/delta) with the downregulation of WT1 in human melanoma and murine melanoma cell lines. The aim of this work was to analyse the expression of WT1 and its association with PPARβ/δ in samples of healthy and melanoma-affected skin of horses by immunohistochemistry. WT1 protein expression was detected in healthy skin, mainly in the epidermis, hair follicle, sebaceous gland and sweat gland, while no expression was observed in equine melanoma tissues. Moreover, it was observed that PPARβ/δ has a basal expression in healthy skin and that it is overexpressed in melanoma. These results were confirmed by a densitometric analysis, where a significant increase of the WT1-positive area was observed in healthy skin (128.66 ± 19.84 pixels 106) compared with that observed in melanoma (1.94 ± 0.04 pixels 106). On the other hand, a positive area with an expression of PPARβ/δ in healthy skin (214.94 ± 11.85 pixels 106) was significantly decreased compared to melanoma (624.86 ± 181.93 pixels 106). These data suggest that there could be a regulation between WT1 and PPARβ/δ in this disease in horses.

Published: February 2021

The aim of this study was to demonstrate a relationship between the occurrence of clinical signs of brain involvement in dogs with babesiosis and the concentration of manganese (Mn) in their serum. The study included seven dogs with early babesiosis (Group 1), seven dogs with cerebral babesiosis (Group 2) and seven healthy dogs (Group 3). Haematological and biochemical blood tests were performed in all dogs, and the results were analysed statistically. The Mann–Whitney rank test was used to demonstrate the differences in Mn concentrations, as well as other haematological and biochemical parameters between groups. In dogs in Group 2 with cerebral babesiosis, as compared to dogs in Groups 1 and 3, a statistically significant increase in serum Mn concentration was shown (P = 0.002 and P = 0.029) that may have been associated with the development of anaemia and/or impairment of liver function. Given the well-established neurotoxic effects of Mn in humans, experimental rodents and primates, additional studies on the role of Mn in the pathogenesis of the cerebral form of canine babesiosis are warranted.

Published: February 2021

Percutaneous aspiration–injection–reaspiration (PAIR), also called sclerotherapy, is a minimally invasive, inexpensive and safe technique for the treatment of abdominal cysts in humans. A study was planned to evaluate the feasibility of this procedure in the management of abdominal cysts in sheep and goat. Adult ewes (n= 5) and one doe (n= 1) found to have abdominal cysts (one cyst/animal) on repeated survey ultrasonography (USG) were included in the study. The animals were restrained in standing position. A hypodermic needle (G-18) securely attached to a 10-mL Dispovan syringe was carefully passed under ultrasound guidance into the abdominal cyst in all these animals. Depending on the size of the cyst, 1.0–5.5 mL fluid was aspirated, and 0.5–2.0 mL of 20% hypertonic saline solution infused. The needle was thereafter keptin situfor 10 min. The maximum possible volume of the cyst content was reaspirated and the needle withdrawn. On day 7, sclerotherapy was repeated in five animals showing no appreciable reduction in cyst size by USG. USG was repeated on days 30 and 90. All the cysts except one responded to PAIR during this period. From this study it can be concluded that sclerotherapy using hypertonic saline (20%) is a minimally invasive, inexpensive, effective and safe interventional ultrasonographic technique for the treatment of abdominal cysts in sheep and goats. However, the procedure needs further evaluation after using different sclerotic agents of varying concentrations and duration of their retention in the cysts in a sufficient number of animals with cysts.

Published: February 2021

In this study, a simple, fully validated and rapid reversed-phase HPLC with photodiode array detector method was developed for the simultaneous determination of 11 selected phenolic antioxidants over 33 min in personal care and food samples containing extracts of green apple, pomegranate (Ponica granatum) and argan oil (Argania spinosa). The method was performed using NUCLEODUR C18 column 5 µm particle size and 12.5 cm length. The HPLC mobile phase was prepared as follows, solution A: 1% aqueous acetic acid and solution B: Acetonitrile. The method was gradient at flow rate 1.0 mL/min with a simple mobile phase, minimal sample preparation, and diminished organic solvent usage (3% acetonitrile for almost 90% of the run time). The detection was carried out at 278 nm. The method presented good precision and accuracy with RSD% values ranged between 0.33 and 1.94% and wide linear range. The developed method was successfully applied on 67 personal care and food products present in Egyptian market and can be used for routine screening in laboratory for the regular quality control of the antioxidant content for products containing the mentioned extracts.
Mid-term results and predictors of restenosis in patients undergoing endovascular therapy for isolated popliteal artery steno-occlusive disease
Authors: Nguyen Dat Tin , Bayerle Patrik , Vértes Miklós , Bérczi Ákos , Dósa Edit
Published: February 2021

Background and aim

There is only a limited number of major publications on the outcome of interventions for isolated popliteal artery stenosis. The purpose of this study was to report our results on mid-term patency and predictors of restenosis.

Patients and methods

This single-center retrospective study included 61 symptomatic patients (males, N = 33; median age, 65.1 years [IQR, 60.7–71.9 years]; Rutherford grade 4–6, N = 14) with at least two patent crural arteries, whose atherosclerotic stenoses/occlusions were treated with percutaneous transluminal angioplasty (PTA) or stenting (using self-expanding bare-metal Astron Pulsar stents) between 2011 and 2018.

Results

Twenty-six patients had PTA, while 35 underwent stenting. The median follow-up was 29 months (IQR, 10–47 months). The primary patency rates were not significantly different (P = 0.629) between PTA and stenting groups. Restenosis developed in nine patients (34.6%) in the PTA group, and in 12 (34.3%) in the stenting group. Restenotic lesions required re-intervention in nine cases (100%) in the PTA group, and in eight (66.7%) in the stenting group. Restenosis developed significantly less frequently (P = 0.010) in patients with a popliteal/P1 stent; the primary patency rates were also significantly better (P = 0.018) in patients with a popliteal/P1 stent when compared to popliteal/P2 plus multi-segment stents. Cox regression analysis identified lesion location as a predictor of in-stent restenosis (HR, 2.5; 95% CI, 1.2–5.5; P = 0.019).

Conclusion

Stenting was not superior when compared to PTA (if selective stenting was not considered as loss of patency). Follow-up should be more thorough in patients undergoing popliteal/P2 or multi-segment stenting.
Aprender a aprender en la universidad: perspectivas del profesorado y de los estudiantes
Authors: García-García Fran-J. , López-Francés Inmaculada , Moctezuma-Ramírez Evelyn-E. , Pérez-Pérez Cruz
Published: February 2021

El objetivo de este estudio fue interpretar las perspectivas del profesorado y de los estudiantes universitarios acerca de la competencia “aprender a aprender”. Llevamos a cabo grupos de discusión con ambos colectivos y nos apoyamos en el Modelo GIPU-EA, ya que era lo suficientemente operativo e integrador como para sistematizar las codificaciones. Analizamos el enraizamiento y la densidad, y calculamos un puntaje de coherencia intradimensional. Los resultados mostraron dos perfiles diferentes en la percepción de la competencia. Uno se ajustó al profesorado y otro a los estudiantes. Las implicaciones para la docencia universitaria se discuten al final del documento, junto con las limitaciones del estudio.

Propuesta de un modelo de liderazgo pedagógico para directores de centros concertados de Educación Primaria. Aplicación del análisis factorial confirmatorio
Authors: Sanz-Ponce Roberto , López-Luján Elena , González-Bertolín Aurelio
Published: February 2021

Se pretende confirmar un modelo de liderazgo pedagógico para directores de Educación Primaria de centros concertados. Han participado 68 directores, mediante un estudio de encuesta de tendencia. Se han realizado: análisis factorial exploratorio (máxima verosimilitud y rotación Promax) y análisis factorial confirmatorio (AMOS 5.0©). El resultado más relevante es la no confirmación del modelo. Se pone de manifi esto que el ejercicio del liderazgo compartido no se corresponde necesariamente con una actuación orientada a la mejora del desempeño docente del profesorado, ni a la capacidad de propiciar transformaciones en el funcionamiento de los centros y/o en la colaboración con las familias.

Resumo O artigo discute algumas das relações entre mães e processos de Estado, tendo em vista sobretudo os movimentos de mães e familiares de vítimas de violência institucional, as análises inaugurais a esse respeito nas ciências sociais brasileiras, as implicações dessas mães e familiares nas políticas de produção de conhecimento e na crise democrática que atravessamos. Na primeira parte do artigo, retomamos pesquisas fundamentais que constituíram o campo de estudos que pensa desde a perspectiva do envolvimento de mães em movimentos de reivindicação por direitos e justiça. A segunda parte do artigo propõe-se à apresentação de alguns dos desdobramentos, em nossas próprias pesquisas, desse envolvimento e da produção de um conhecimento compartilhado entre pesquisadoras e o que se denomina usualmente como “interlocutoras”. A última parte do artigo discute a posicionalidade dos movimentos de mães e familiares de vítimas de violência junto ao que se tem chamado de “crise democrática brasileira”. Com isso, buscamos oferecer uma contribuição para o campo de pesquisas que se voltam, já há algum tempo, à produção recíproca entre gênero e Estado.
The Afro-Asian Silk Road: Chinese Experiments in Postcolonial Premodernity
Authors: Chin Tamara T.
Published: February 2021

This essay approaches the Silk Road as a modern narrative of China's connected past, rather than as a historical fact. The Chinese termSilk Road(sichou zhi lu; 丝绸之路) first gained currency after the 1955 Afro-Asian Conference in Bandung as part of the lexicon of anticolonial solidarity. During the Cold War, China's Afro-Asian Silk Road, different from the West's Europe-Asia Silk Road, prompted new interest in the linguistic dimension of connected history. Language contact traditionally held limited significance in European and Chinese philology because linguistic divisions were understood in terms of nation or language family. For Afro-Asian scholars and writers, however, precolonial language contact became a portent of postcolonial exchange. They shifted attention from genetic word roots to historical routes (e.g., loanwords). Within a longer history of what I call “contact philology,” China's short-lived collaborations refashioned the Orient as Afro-Asia and presented an (unfinished) critique of the tropes with which we narrate the connected past.
The COVID-19 Shock and Consumer Credit: Evidence from Credit Card Data
Authors: Horvath Akos , Kay Benjamin , Wix Carlo
Published: February 2021

We use credit card data from the Federal Reserve Board's FR Y-14M reports to study the impact of the COVID-19 shock on the use and availability of consumer credit across borrower types from March through August 2020. We document an initial sharp decrease in credit card transactions and outstanding balances in March and April. While spending starts to recover by May, especially for risky borrowers, balances remain depressed overall. We find a strong negative impact of local pandemic severity on credit use, which becomes smaller over time, consistent with pandemic fatigue. Restrictive public health interventions also negatively affect credit use, but the pandemic itself is the main driver. We further document a large reduction in credit card originations, especially to risky borrowers. Consistent with a tightening of credit supply and a flight-to-safety response of banks, we find an increase in interest rates of newly issued credit cards to less creditworthy borrowers.
La indumentaria masculina en clave social. Córdoba, gobernación del Tucumán, 1574-1620
Authors: González Navarro Constanza
Published: February 2021

El presente artículo aborda el problema de la indumentaria masculina, particularmente entre los sectores medios y altos de la sociedad cordobesa temprano-colonial para explorar la manera en que las materialidades pudieron configurar, y no solo expresar, las diferencias sociales en una de las ciudades más meridionales del virreinato del Perú. A partir de un corpus documental compuesto fundamentalmente por inventarios post mortem, pero también por procesos judiciales, relaciones y actas capitulares, se busca reconocer no solo los rasgos estéticos de la indumentaria masculina, sino reflexionar sobre su contexto histórico particular y la dinámica general que subyace a la elección o adopción de un estilo vestimentario específico.
Disrupting narratives of isolation: the production and circulation of ideas in Colombia about Latin America’s progress, 1870–1900
Authors: Campuzano-Hoyos Jairo
Published: February 2021

Colombians were not isolated during the last third of the nineteenth century. Transportation difficulties that slowed the movement of people and goods—a particularly challenging issue in the Andean region—proved less of a hindrance for the movement of ideas. Many intellectuals, seeking knowledge about Latin America’s latest progress, worked diligently to promote the spread and understanding of global ideas among fellow Colombians. They looked to learn from republics in the region, with whom they also developed mutually beneficial intellectual and material relationships. Colombian intellectuals, many of whom played a decisive role in diplomatic postings abroad, facilitated this circulation of ideas within Colombia.

Efecto de la utilización de pulseras inteligentes para el incremento de la actividad física en adolescentes de un entorno rural: Estudio Piloto
Authors: Díaz-Quesada Gema , Puga-González Esther , Muñoz-Galiano Inés M.
Published: February 2021

Los niveles de actividad física (AF) cada vez son más bajos. Las recomendaciones de 60 minutos de actividad física moderada-vigorosa (AFMV) y entre 10.000 y 16.000 pasos al día para niños y adolescentes, solo son cumplidas por grupos minoritarios. Los programas de intervención utilizando dispositivos inteligentes son una buena opción para el incremento de la AF. El objetivo de este estudio fue evaluar el efecto de la utilización de pulseras inteligentes para el incremento de AF en una muestra de un entorno rural. Un total de ocho estudiantes de entre 14 y 16 años participaron en este estudio. Los sujetos portaron una pulsera de actividad física Xiaomi Mi Band 4 durante dos semanas, donde se registró el número de pasos y los minutos de AFMV. La primera Semana de Control (S1), fue una semana de rutina escolar habitual. La segunda Semana de Intervención (S2), fue una intervención de promoción de la AF orientada al incremento de la misma por medio de retos. Los sujetos mostraron en la primera semana una media de 7.200 pasos/día y 173 minutos/día y, durante la segunda, una media de 12.300 pasos/día y 212 minutos/día de AFMV, mostrando así un aumento importante durante la segunda semana, respecto a la primera semana. Diferentes estudios muestran grandes incrementos de AFMV al aplicar programas de intervención, consiguiendo así que se cumplan las recomendaciones mínimas diarias de minutos de AFMV y de pasos. Se evidencia que las pulseras de AF influyen de manera positiva para el aumento de los niveles de AF, además de resultar un instrumento motivante para el alumnado.
Presencia de la mujer en las juntas directivas de los clubes de fútbol. Un caso de estudio en la Región de Murcia (España)
Authors: Giménez Pérez-Chuecos Marcos , Rodríguez-Ferrán Olga
Published: February 2021

La presencia de la mujer en las juntas directivas se hace difícil debido a que estas organizaciones se crearon para los hombres, dificultando así la presencia y relevancia de la mujer en las mismas. El objetivo del siguiente estudio consiste en examinar la ausencia o presencia de la participación de las mujeres a nivel organizativo (cargos directivos) en la temporada 2019/20 en los clubes de fútbol y fútbol sala de la Región de Murcia. Para el estudio se estilizó como muestra el total de las personas con cargos directivos de los equipos de fútbol y fútbol sala de la Región de Murcia (n=1020), que con fecha de septiembre del 2019 se encontraban registrados en el Registro Oficial de Clubs Deportivos de la Comunidad Autónoma de la Región de Murcia. Se llevó a cabo una metodología observacional en la que se consideraron como variables: a) modalidad del club (fútbol o fútbol sala); b) género (masculino o femenino) y; c) figura (presidente; vicepresidente 1º; vicepresidente 2º; vicepresidente 3º; vicepresidente/a 4º; secretario/a; tesorero/a; 1º vocal; 2º vocal; 3º vocal; 4º vocal; y otros cargos). Los resultados exponen que el porcentaje medio de mujeres en los clubes de fútbol es del 14,28% y del 21,70% en los clubes de fútbol sala, además de que, en el 53,36% de los clubes de la Región de Murcia no hay ninguna mujer en su junta directiva. Se extrae como conclusión que las mujeres aparecen menos que los hombres en los puestos directivos, y que, además, los puestos que ocupan son de menor relevancia dentro de los clubes.

Published: February 2021

Parvalbumin, sebuah protein sarkoplasmik merupakan penyebab utama alergi ikan. Proses pencucian pada pembuatan surimi dapat menghilangkan protein-protein sarkoplasmik dari daging ikan. Oleh karena itu, penelitian ini dilakukan untuk menentukan efek pencucian dan pemanasan serta penambahan enzim terhadap kandungan parvalbumin surimi. Profil protein divisualisasikan menggunakan sodium-deodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) dan intensitasnya diukur. Hasil SDS-PAGE memperlihatkan bahwa proses pencucian menghilangkan protein-protein sarkoplasmik yang diindikasikan dengan menurunnya jumlah dan intensitas pita protein pada surimi. Selain itu, profil protein dari air cucian hampir sama dengan profil protein dari daging ikan segar, menunjukkan bahwa sebagian besar protein dari daging ikan segar terbawa oleh air cucian. Adapun kandungan parvalbumin pada surimi menurun hingga 95% setelah proses pencucian, dan proses pemanasan maupun penambahan enzim tidak berpengaruh terhadap penurunan parvalbumin. Oleh karena alergenitas ikan berkorelasi dengan kandungan parvalbumin, surimi dapat menjadi alternatif sumber hipoalergenik protein ikan.
O espólio teatral do dramaturgo português Gervásio Lobato / The Theatrical Collection of the Portuguese Playwright Gervásio Lobato
Authors: Barbieri Claudia
Published: February 2021

Resumo: Gervásio Lobato (1845-1895) foi um proeminente dramaturgo português, além de romancista, contista, tradutor e jornalista. Há, contudo, dissonâncias entre a expressiva recepção crítica que sua obra teatral recebeu enquanto o escritor ainda era vivo e o subsequente apagamento de seu nome e de sua dramaturgia nos volumes de história do teatro português publicados a partir de 1960. O artigo tem por objetivos formular algumas hipóteses para explicar este descompasso entre recepção e crítica, além de discorrer sobre a organização do espólio do escritor, pertencente ao Museu Nacional do Teatro e da Dança, em Lisboa. A dificuldade de acesso aos arquivos, a ausência de reedições das peças, a variedade de suportes são alguns entraves que podem ser elencados e que precisam ser resolvidos ao longo do processo de resgate do teatro gervasiano.Palavras-chave: Gervásio Lobato; teatro português; organização de espólio.Abstract: Gervásio Lobato (1845-1895) was a prominent Portuguese playwright, as well as a novelist, short story writer, translator and journalist. There are, however, dissonances between the expressive critical reception that his theatrical work received while the writer was still alive and the subsequent erasure of his name and dramaturgy in the volumes of Portuguese theater history published since 1960. The article aims to formulate some hypotheses to explain this mismatch between reception and criticism, in addition to discussing the organization of the writer’s estate, belonging to the Museum of Theater and Dance, in Lisbon. The difficulty of accessing the archives, the absence of reissues of the plays, the variety of supports are some obstacles that can be listed and that need to be resolved throughout the process of rescuing the Gervasian theater.Keywords: Gervásio Lobato; Portuguese theater; theatrical collection organization.
The internationalization of architectural practice : Mobilizing dependence to secure and enhance (relational) autonomy on the construction site
Authors: Dimitrova Venetsiya
Published: February 2021

More than any other profession, architecture has been shaped by the tension between autonomy and heteronomy. Recently, however, this dichotomy is seen as unproductive for understanding architects’ practices in-depth, especially in the context of the growing internationalization that is transforming and restructuring architectural practice. The paper applies the lens of ‘relational autonomy’, grasping architectural practice in relation to the actions of other built environment professionals, and to material artefacts. Dependence is framed not as a threat but as a productive potential. The focus of the paper is on the practices of less prominent architects in celebrity global firms. More specifically, the paper explores the practices enacted during the actual materialization of design-ambitious edifices, on-site and in the workshops of sub-contractors. The main argument is that less visible architects can secure and enhance the (relational) autonomy of global architects during construction, by actively shaping a specific working context, where they can purposefully mobilize dependence. Practices during construction generate new opportunities for creative engagement and enhance architects’ influence over processes beyond their autonomous actions, thereby enabling the making of products with high symbolic value.
(Un)real estate : Online staging of investment-driven housing projects in Vienna
Authors: Aigner Anita
Published: February 2021

If we want to understand why housing is increasingly becoming a global investment product and the subject of surplus consumption, we must also look at the advertising infrastructures and image products that have been profoundly transformed by new digital technologies. This article examines the promotional staging of luxury and investment apartments using the example of websites that advertise upscale new construction projects in Vienna. The central question is how, and with which forms of aesthetic staging, processes of emotional and temporal entanglement are set in motion. For the analysis, Gernot Böhme’s theory of aesthetic economy and concepts of ANT-informed economic sociology are used. It is argued that breathtakingly realistic architectural renderings should not only be seen as representations, but as ‘market devices’ which, together with the technical-digital environment in which they are embedded, (co-)shape our affects, our desire and our consumer behaviour. The aesthetic work that is invested in the online staging of residential real estate does not simply serve to better imagine buildings not yet built, but rather to sell apartments at an ever earlier date – thus to accelerate the capital turnover.
Critical Care Anywhere: Principles for High-Functioning Management in Low-Resource Environments
Authors: Stankiewicz Jason , Ward Robert , McCurdy Michael
Published: February 2021

Critically ill patients can present at any time and location, and they demand high quality care. Historical experiences from military, wilderness, and disaster medicine settings have helped shape the modern concept of caring for the most severely ill with limited available resources. We introduce a method to help design a successful critical care medical support endeavor, which includes properly defining components of Navigation, Environment, Resupply, Energy, Unconventional problems, and Support (NEREUS). Additionally, we provide recommendations for optimal team personnel composition, including utilization of paramedics, critical care providers, nurses, and respiratory therapists across the spectrum of care provided at point of injury, en route to definitive care, and definitive care. A review of critical care principles relevant to the austere setting proceeds with a systematic organization according to airway, breathing, circulation, and neurologic management. Lastly, we employ our proposed method of organizing a critical care medical support endeavor to a post-hurricane scenario. In summary, this review provides the historical background, modern definition, and practical framework for successfully administering critical care in scenarios with limited available resources. We emphasize the need to appropriately adapt critical care concepts to meet the unique demands of a specific scenario.
Surviving Mold Indoor Environmental Professional Panel - Consensus for microbial remediation 2020
Authors: et.al. The CIRS Academy
Published: February 2021

In the absence of Federal safety standards for occupancy of buildings with a history of water intrusion, remediation of water-damaged buildings (WDB) has focused on building health issues, including correction of defects in the building envelope, microbial growth and removal of contaminated materials. To date, no guidelines have been published that incorporate human health parameters into professional recommendations regarding treatment of the potentially unsafe conditions found in WDB.This document is a consensus statement that expands on existing professional society recommendations by including guidelines for remediation of buildingsto be occupied by known, previously sickened patients.

Published: February 2021

Background: Meningiomas are one of the most common primary intracranial tumours. The incidence, varieties of tumour, site, imaging findings, resectability, outcome and prognosis vary from tumour to tumour. The understanding of these characteristics is essential in the management of meningiomas.Methods: An observational study was carried out among 50 patients with imaging proven meningioma and involved recording of age, gender, clinical history, physical examination, imaging findings, intraoperative characteristics, anatomical and pathological diagnosis. The parameters evaluated in the study were gender distribution, age distribution, presenting symptoms, neurological deficits, mri findings, volume of tumour, intraoperative findings, grade of excision, anatomical, pathological diagnosis and recurrence rates.Results: The male to female ratio was 1:2.57, with 50-70 years being the most affected population. The common symptomatology was that of features of raised ICP with motor deficit as the common neurological abnormality. Simpson grade 2 was the common clearance obtained. 3 common sites were parasagittal, sphenoid wing and convexity. Commonest histological type was transitional. Recurrence rate was 6%. This study also pointed out general imaging and intraoperative characteristics of Grade 3 tumours as T2 hyperintensity, heterogeneous, with significant perilesional oedema and intensely contrast enhancing, high vascularity, friable, suckable and ill-defined margins.Conclusions: The study enables us to understand the general trend of presentation, imaging and surgical properties of Meningiomas and to compare with international standards. It also helps us to finger out the possible high-grade lesions even before the pathological diagnosis is obtained.
Encuesta BIM: América Latina y el Caribe 2020
Authors: Lacaze Laura
Published: February 2021

Este informe presenta los resultados de una primera encuesta regional de empresas del sector construcción de América Latina y el Caribe para entender mejor la lenta adopción de Building Information Modelling (BIM), una nueva metodología de trabajo colaborativo en base a modelos de datos que contribuye enormemente a la mejora de la productividad del sector. BIM facilita la colaboración entre empresas en un sector donde la falta de coordinación conlleva grandes costos. Pese al reconocimiento unánime de las ventajas del BIM, las empresas encuestadas señalan que la falta de demanda y la ausencia de capacidades y estándares BIM han frenado hasta ahora su adopción. El informe busca ofrecer insumos a actores clave del sector de AEC, a hacedores de política pública, así como a grupos de interés privados y académicos, para orientar mejor sus esfuerzos de apoyo a la transición digital del sector.

Published: February 2021

En el presente trabajo se hace una breve descripción del desarrollo de los instrumentos de detección y de registro de señales sísmicas, considerando algunos aspectos técnicos e históricos. Esta descripción parte de los primeros sismoscopios, que evolucionaron en sismómetros, y culmina con los sismógrafos, instrumentos que detectan y registran las señales sísmicas. En relación con estos últimos, se analiza cómo del sismógrafo mecánico se pasó al electrodinámico para llegar al sismógrafo moderno con registro digital. En la parte final del documento se plantea la necesidad de incluir los metadatos descriptivos de las redes sismológicas además de los datos registrados por las estaciones que la conforman. Se presentan los metadatos de las redes sismológicas que operan en la mayoría de los países de la región de Latinoamérica y del Caribe, desde el río Bravo en el norte de México hasta la punta más meridional de la Patagonia argentina. La recopilación de estos metadatos fue posible gracias a los aportes, valiosísimos y desinteresados, de muchos colegas que trabajan en dichas redes, a quienes los autores del presente trabajo expresan el mayor de los agradecimientos.

Thermography is a technique that is being proposed as an auxiliary tool in breast cancer screening. It gains importance, especially due to the increased incidence of this cancer in the Brazilian female population. These images are also used for the validation of three-dimensional numerical simulations. The production of a more realistic and personalized breast model would allow a more accurate estimate of the sensitivity of thermography as a technique capable of early detection of breast cancer. This work proposes the development of a methodology to produce a custom three-dimensional breast geometry from the manually extracted curves of the thermograms contained in UFPE Thermographic Image Database. With this geometry, parametric analyzes were performed, seeking to understand the influence of tumor depth and size on the calculated temperature profile.
