Riboflavin removal by commercial bentonites and charcoals in white and red wine
Authors: Vendramin Veronica , Primerano Simona , Leserri Giampiero , Paniccia Giulio , Vincenzi Simone
Published: September 2021

Riboflavin (RF) represents one of the primary molecules undergoing photo-degradation in wine and its excited form act as intermediate in light-induced oxidation reactions responsible for the light-struck fault. A recent study revealed bentonites (BENs) and charcoals (CHAs) as the most promising fining agents for riboflavin removal in model wine. This work explored their potential on both white and red wine. Eleven BENs and eleven CHAs were compared. BENs exhibited a limited capacity, while decolouring carbons confirmed a great attitude to RF removal in white wine even at low dosages. Nevertheless, CHAs efficiency shows a sensible reduction in red wine.

Published: September 2021

We studied the effect of a high linolenic acid diet supplementation with synthetic (vitamin E + selenium) or veg-etal mix rich in natural antioxidants (grape skin + oregano) on live performances, carcass and meat quality, fatty acid composition and oxidative stability of intramuscular lipids of Longissimus thoracis et lumborum muscle in medium-heavy pigs. Neither carcass traits nor chemical proximate composition of meat was affected by dietary treatments. Linseed dietary inclusion reduced the n-6:n-3 polyunsaturated fatty acids ratio and increased long-chain n-3 precursor, fundamental for human health. Our results offer new opportunities to use products more acceptable by consumers and are more eco-friendly.

Published: September 2021

Citrus is the most cultivated fruit crop in the world and occupies a place of considerable importance in the country’s economy. Almost 33% of the citrus fruits are processed for juice production; however, a great amount of wastes, including peels, segment membranes, and seeds are also produced. Indeed, citrus fruits consist of 45% juice, 26% pulp, 27% peels, and 2% seeds. Pruning, a cultural practice involving the removal of tree branches and limbs, was applied to improve fruit’s quality. A large amount of leaves are produced through pruning. These agri-food matrices contain a wide range of bioactive phytochemicals compared to fruits. The present review covers the past 5 years of research carried out in chemistry, health properties, and applications in food and nutraceutical industries of all portions of citrus fruit and its major bioactive compounds. Additionally, patents are also included.

Published: September 2021

Today, the usage of natural additives in the food matrix has increased. Natural antimicrobial compounds include peptides, enzymes, bacteriocins, bacteriophages, plant extracts, essential oils, and fermented compounds that can be used as alternatives to chemical antimicrobials. Plant extracts and essential oils contain terpenes, flavonoids, aldehydes, and phenolic compounds that cause antimicrobial and antioxidant activity. The synergistic activity of compounds synthesized from lactic acid bacteria (LAB) prevents the growth of bacteria and fungi. In addition to removing mycotoxins, LAB compounds have antioxidant and anticancer potentials and increase food safety and nutritional value. One of these antimicrobial molecules is bacteriocin, which is made by various microorganisms. Nisin is one of these bioactive peptides that are used widely in food bio-preservation. Antimicrobial peptides can be used alone or along with other compounds to enhance food security. This article reviews natural preservatives and their applications in food products.

Authors: Heshmati Ali , Khorshidi Mina , Mousavi Khaneghah Amin
Published: September 2021

The contamination of aflatoxins (AFs) in 120 samples of sesame seeds, tahini, and tahini halva collected from Iran’s market were evaluated. The exposed risk due to ingestion of aflatoxin B1 (AFB1) via their consumption was estimated with the aid of the Monte Carlo simulation (MCS). The highest prevalence of AF (55%) was associated with sesame seed samples, followed by tahini (45%) and tahini halva (32.5%). The AFB1 concentration in sesame seeds, tahini, and tahini halva was in the ranges of 0.21–12.35, 0.23–5.81, and 0.27–3.56 ?g/kg, respectively. The concentration of the total aflatoxin (TAF) in 7 (17.5%), 8 (20%), and 2 (5%) samples of sesame seeds, tahini, and tahini halva, respectively, was below the limit of European regulations (4 µg/kg), while the levels of AFB1 in 10 (25%), 7 (17.5%), and 6 (15%) samples of sesame seeds, tahini, and tahini halva, respectively, were higher than the European regulations (2 µg/kg). As the percentile 50 and 95 of margin of exposure (MOE) with AFB1 for sesame seed, tahini, and tahini halva was more than 10,000, it could conclude the intake of aflatoxin through the consumption of mentioned products did pose a not remarkable cancer risk for adults.

Published: September 2021

Este proyecto estudia la morfología del brazo humano con la finalidad de construir un robot capaz de imitar los movimientos del mismo, aprenderlos y repetirlos bajo una rutina de control cinemático, para esto fue necesario realizar un aprendizaje de trayectorias, las cuales se obtienen mediante visión artificial haciendo uso del Kinect; del cual se extraen las coordenadas espaciales de cada articulación, y posteriormente se procesan mediante un modelo matemático para obtener las posiciones articulares, calcular el modelo cinemático del robot, y desarrollar una rutina para el control cinemático que establece la relación entre las velocidades de las articulaciones. El sistema le permite al usuario poder iniciar un aprendizaje de sus movimientos, y posteriormente simular dicho aprendizaje en el robot virtual. Así como también activar el robot físico para que realice los movimientos aprendidos. Al comparar los resultados se determinó que la desviación estándar de las trayectorias con y sin control, no cambia en mayor medida; pero los puntos que se encuentran dentro de la desviación en la parte de control son más proporcionales, esto debido a que la estabilidad de las trayectorias mejora al aplicarle el control cinemático.

Published: September 2021

La deserción universitaria y en especial, en la educación a distancia, es un problema que afecta en menor o mayor medida a las diferentes instituciones educativas, lo que demanda el diseño de estrategias de prevención y atención. En este sentido se presenta aquí un sistema experto de orientación vocacional. Como objetivo, se diseñó un sistema experto basado en reglas de producción mediante el lenguaje de programación Prolog y el apoyo de expertos en psicología, sociología, economía, educación e ingeniería informática. Asimismo, se realizó una sistemática revisión de literatura, para determinar las causas de la deserción y los estilos de orientación vocacional prevalentes. Se usaron las reglas de producción para la construcción de la base de conocimientos y la implementación de la interfaz de usuario se hizo mediante Visual Prolog ®. Se obtuvo un sistema experto que, a partir de los intereses profesionales, las habilidades específicas y las competencias de los aspirantes, posibilita la orientación vocacional y se ajusta a estos procesos de la misma forma que se hace tradicionalmente, con la ventaja que este puede ser replicado. Algunos aspectos como los entornos socioeconómicos, la perspectiva de género y la alfabetización digital, deberían ser tenidos en cuenta al momento de diseñar los sistemas de orientación vocacional, de tal forma que sus recomendaciones sean más relevantes; esto toma especial importancia en entornos virtuales de aprendizaje. Esto no fue evidenciado en la revisión bibliográfica.

Published: September 2021

ABSTRACT: Objective: To investigate the variation of anthropometric indicators from 2013 to 2019 and the factors associated with obesity in Brazil, using information from the National Health Survey. Methods: Cross-sectional study with cluster sampling and simple random sampling in the three stages. Measurements of weight and height among participants in 2013 (n=59,592) and in 2019 (n=6,672) were used. Differences in obesity prevalence were tested by Student’s t test for independent samples. To identify the sociodemographic factors and health problems associated with obesity, we used Poisson regression models with robust variance and crude and age-adjusted prevalence ratios to test the associations. Results: From 2013 to 2019, prevalence of obesity increased significantly, from 20.8 to 25.9%. Among men, the greatest increases were found in the 40-59 age group (9.1%) and in the median income category (8.3%). Among women, the greatest rises were found among those with low education (8.7%) and non-white ones (6.0%). For both males and females, factors associated with obesity were age, to live with a partner, level of instruction directly associated among men, and inversely associated among women. In 2019, for males, the crude and adjusted prevalence ratios were significant for high cholesterol, high blood pressure and at least one chronic non-communicable disease and, for females, for poor self-rated health, high blood pressure, diabetes, and at least one chronic non-communicable. Conclusion: It is necessary to implement intersectoral policies to promote changes in eating habits and encourage the practice of physical activity, taking into account economic, social, cultural, and environmental aspects.
Time-dependent reliability of concrete bridges considering climate change and overload
Authors: Luo Wei , Pang Bo , Shi Chengcheng , Liu Yinshan , Wang Yuanfeng
Published: September 2021

Increased temperature and carbon dioxide concentration caused by climate change will aggravate the creep shrinkage and structural durability of concrete bridges. Overloading also has a great impact on the time-dependent reliability of existing bridges. This research paper analyses the time-dependent reliability of bridges based on climate change and overload. By improving the concrete carbonation model and referring to the B4 model of concrete creep, the effects of ambient temperature and humidity on concrete under different emission-reduction scenarios were considered. At the same time, given the serious problems of vehicle overload in China, combining different overload scenarios with climate change led to the establishment of a time-dependent reliability model for precast-concrete bridges. The results showed that as the overload rate increased, the time-dependent reliability degradation rate of a case study bridge accelerated. Under the scenario considering both high greenhouse gas emissions and the maximum overload rate, the service life of the case study bridge decreased to 50% of its design life.

Published: September 2021

Phase-change material (PCM) is a promising thermal storage medium through its state change, which enables the storage of abundant thermal energy and a sustainable supply afterward. Sodium acetate hydrated salt (sodium acetate trihydrate (CH3COONa·3H2O)) is a suitable PCM in the lower-temperature range for solar thermal energy storage. However, its phase separation phenomenon restricts its actual utilization. In this study, disodium hydrogen phosphate dodecahydrate (Na2HPO4·12H2O) and sodium metasilicate nonahydrate (Na2SiO3·9H2O) were employed as additives for sodium acetate trihydrate hydrated salt to prepare a qualified composite hydrated salt with excellent comprehensive properties. The study indicates that (a) the optimal mass ratio of sodium acetate trihydrate to disodium hydrogen phosphate dodecahydrate is 8.5:1.5, its undercooling degree varying within 2.1°C during 150 heating–cooling cycles, and (b) further addition of 1.5% sodium metasilicate nonahydrate could significantly enhance the stability of the heating–cooling cycle of the optimal composite hydrated salt, the undercooling degree becoming less than 1.3°C, and the heat-release platform is at about 51°C during 200 heating–cooling cycles.

The article offers methodological tools to diagnose the weaknesses and strengths of a region’s socio-economic and innovative development. The topicality of the issue is determined by the need to define the priorities for the regional strategizing. The methods of analytical diagnostics, expert survey, SWOT and PEST analyses underlie the methodology of the study. The article applies the diagnostics tools to the economy of Lugansk People’s Republic and gives the results. The study characterizes the local factors of the regional economy affecting the level of the economic and innovative development in Lugansk People’s Republic. The article also gives the conclusions made from the analysis of the possible external impacts (opportunities and threats) in the COVID-19 pandemics in terms of social, economic, and innovative trends. For example, PEST analysis is used to calculate consolidated weighted indicators for the socio-economic and innovative development in Lugansk People’s Republic. A group of political factors is seen to have an adverse effect due to the Republic’s status as a breakaway region and a threat of military escalation. A lack of properly functioning banking and financing systems, flight and railway connections, low investment interest in the region’s economy show the most serious detrimental impact among other economic factors. A weighted indicator in the group of social factors is positive due to the following institutions: protection of health and labor, education, culture and sport. A negative weighted value for a technological component could be explained by an extensive physical and moral depreciation of the fixed assets, a low use of production capacities, a lack of local raw materials resources. Cross-sectional SWOT analysis makes the authors conclude about a significant impact of the weaknesses on the socio-economic and innovative development of a region, which should guide the development of priority measures in the public economic strategy. Further research is seen to be connected with the justification and development of the efficient strategy for the sustainable self-development of Lugansk People’s Republic.

The state of environmental protection of natural environment from negative processes has become an integral part of sustainable mining. The analytical review shows the ways of geoinformation system’s preparing a to ensure environmental safety during oil mining process on protected areas. Obtainment information for geoinformation database is based on technologies of aerial remote sensing, experimental modeling of biotic reactions to the impact of technogenic factors by biotesting methods. The geoinformation system should perform observations, assessments, search and regulatory forecasts, based on digital technologies, and develop individual measures for the preservation and restoration of the natural environment. Environmental stresses are usually caused by halogenesis, bitumization, air pollution and mechanogenesis. The use of geoinformation systems to collect information about the state of the natural environment is an essential feature of sustainable mining. Multispectral and panchromatic aerial photography by unmanned aerial vehicle has been successfully used to assess pollution, land degradation, and the effectiveness of land restoration. It is important to develop an unmanned aerial sensing technique for areas, where oil fields and protected are located. Biotesting of the consequences of technogenic transformation of ecosystem components is significantly related to the choice of optimal test objects for conducting experiments. Soil contamination with oil and its processed products affects the condition of all components: plants, microorganisms. It is advisable to develop a methodology for determining the patterns and levels of impact of residual oil and technogenic brines on local natural objects, local soil and water ecosystems based on the results of biotesting. Development of regulations for standard measures for remediation of ecosystems at different levels of pollution, during bitumization, halogenesis of land and water objects. The review shows that there are technological possibilities for creating GIS for monitoring the quality of the natural environment and environmental safety in the areas of oil fields. Digital maps of soils, watersheds, natural and technical systems, the development of technogenic processes and measures to restore the natural environment, allow to provide spatial modeling of natural and technogenic processes. Environmental quality management during oil mining process remains an important goal of geoecological researches.
Comparison of bog phytocenosis ecotopes parameters and peat deposit depths of the Beloe bog (Perm region, Russia)
Authors:   Perm State University, Abdulmanova I.F. , Igosheva E.A. ,   Perm State University
Published: September 2021

It is known that phytoindication of the nature and depth of peat deposits is possible only when, among other factors, the geographical and geomorphological position of the bog systems is taken into account. The aim of this study is to determine whether or not there is a relationship between peat deposit thickness, phytocenosis composition and ecological parameters of plant habitats, using the example of the Beloe Bog located in the Sylvensko-Irenskaya lowland in the south-east of Perm Krai. Measure ments of the depth of the peat deposit were carried out using a peat probe, followed by the determination of the volumes of the peat bog in the GIS (ArcGIS (ESRI)). The diversity of peatland plant com-munities is described, their ecological-cenotic analysis and phytoindication analysis of ecotopes is carried out using Ellenberg and Landolt ecological scales using EcoScaleWin software. The results allow to update the stock data of geological exploration 1969. Ecological-cenotic and phytoindication analyzes revealed differences between pine-dwarf shrub-sphagnum and birch-menyanthes-sphagnum communities. A Spearman correlation coefficient demonstrated a relationship between peat deposit depths and the proportion of Water-Swamp ecological-cenotic group species in the communities, as well as with a number of ecological parameters of the ecotopes. The use of two different ecological scales revealed inconsistency between them. The article substantiates the chosen spatial tactics for measuring the peatland depth of a small irregularly shaped bog and also calculates the time required to measure the thickness of a conven-tional peat deposit of 1000 hectares. The relationship of this work to ongoing palaeoecological research in Perm Krai is highlighted. A comparison is made between the available data on the Beloe Bog and the results of phytoindication studies of the peatland thickness of Western Siberia known to the authors. The limitations and prospects of a series of similar studies in Perm Krai, which will reveal regional and zonal patterns in the spatial structure of bog communities and their relation to the thickness of peat deposits, are considered.

Published: September 2021

Цель: статья посвящена выявлению особенностей обеспечения продовольственной безопасности Японии. Обсуждение: опыт Японии показывает, что усиление роли внешнеэкономических факторов в обеспечении продовольственной безопасности страны стало следствием либерализации торговых отношений после вступления страны в ВТО. Парадоксальным же является то, что при наличии явной проблемы с продовольственным самообеспечением Япония все глубже интегрируется в региональные партнерства и заключает всеобъемлющие соглашения нового типа. Хотя и диктует свои условия по защите сельского хозяйства и национальных производителей продовольствия, во многом несоответствующие принципам ВТО, применяя высокое субсидирование, ценовое регулирование стратегических категорий продовольствия и ограничивая импорт. Результаты: в ходе проведенного исследования был сделан вывод о том, что опыт Японии в обеспечении национальной продовольственной безопасности актуален для Российской Федерации. Выделен новый уровень исследования продовольственной безопасности – трансрегиональный. Обозначены ориентиры для дальнейшего изучения вопроса.

Цель: в работе представлен метод принятия решений, который позволяет провести количественную оценку дохода в зависимости от интенсивности будущего туристического потока как комплексного показателя, отражающего уровень туристического рынка региона или отдельного объекта (гостиничного комплекса, санатория, туристической базы и т.д.). Обсуждение: в качестве практической реализации процесса управления номерным фондом гостиничного комплекса авторами предложено использовать трехуровневую экономико-математическую модель, каждому уровню которой соответствует конкретная задача: на первом уровне – предпрогнозное исследование, обоснование и выбор моделей прогнозирования, на втором – прогнозная модель и количественное значение прогнозируемого показателя, на третьем – модель для принятия ЛПР решения, инструментом которой выступает «Дерево решений». Таким образом, авторы представляют завершенную систему моделей и методов поддержки принятия решений. Результаты: результаты предпрогнозного анализа, разработка прогнозных моделей, построение, адаптация и реализация экономико-математических моделей верхнего уровня даст возможность ЛПР принимать эффективные управленческие решения, тем самым маневрировать материальными ресурсами, выбирать технологии продаж и осуществлять поиск хозяйственных решений, в том числе и в туристско-рекреационной производственной деятельности.

Hacerse hombres. La construcción de masculinidades desde las subjetividades
Authors:   Universidad de Antioquia, Muñoz Sánchez Hernando
Published: September 2021

Los estudios sobre masculinidades son unas de las líneas más recientes dentro de los Estudios de Género. La preocupación por comprender el lugar de opresión que históricamente han vivido las mujeres, ha dejado cierta ausencia en lo que atañe a comprender el lugar y las condiciones de posibilidad a través de las cuales se ejerce el lugar de dominación de los varones. De hecho, esta misma perspectiva que sostiene la existencia de un solo lugar de opresión y un solo lugar de dominación, ha caído en cierto binarismo en la forma en que concibe las relaciones de poder, lo que ha terminado por naturalizar el lugar de los varones, lo cual obstaculiza la comprensión y transformación de estas relaciones. Esto no solo ha afectado el desarrollo de estudios académicos, sino también la orientación de acciones desde los movimientos sociales y del Estado enfocadas hacia la equidad de género, ya que se ha renunciado a vincular directamente a los varones con el proyecto político de unas relaciones de género igualitarias. En el presente libro, el autor se interesa por comprender el proceso de hacerse hombres, ya que se considera necesario analizar a los varones y la masculinidad como productos sociales. Un estudio de este tipo permite también generar una suerte de conciencia en los varones, al plantearles la posibilidad de mirarse en el espejo, lo que se esgrime como un aporte a la creación de otras miradas políticas que generen liderazgo en los hombres para la transformación de las desigualdades de género.
Investigación en ciencias sociales, humanidades y artes. Debates para su valoración
Authors:   Universidad de Antioquia, Vélez Cuartas Gabriel
Published: September 2021

El problema de la validez en la investigación en las ciencias, el humanismo o el arte moderno se ha convertido, en el último siglo, en un problema que pasa de la solidez de los argumentos o la consistencia de la obra creada, a las configuraciones sociales de las redes en las que se gesta ese conocimiento. Cuando investigar se observa como un problema social, político y comunitario, el problema de la verdad se convierte en un asunto de valoración social sobre el resultado ofrecido, después de procesos altamente formalizados. Justo esta transformación es la que permite que la investigación en las artes y las humanidades entre en tensión con la investigación científica experimental, en la definición de lo que significa investigar.
El psicoanálisis en diálogo con la epistemología: un programa de investigación
Authors:   Universidad de Antioquia, Uribe Cano Juan Manuel
Published: September 2021

Si no se puede revisar el psicoanálisis con las herramientas propias de la ciencia, con las epistemologías y sus criterios de validación, no podrá decirse que se eleve por encima del estatuto de un saber pseudocientífico, religioso y lleno de vericuetos propios de saberes gnósticos, de los saberes para iniciados y constituidos desde cenáculos diferentes a los centros de la ciencia y la universidad. Muchas preguntas se suceden de este hecho: ¿las investigaciones que se adelantan en el campo del psicoanálisis son de carácter científico? ¿Existe la posibilidad de que una investigación con el psicoanálisis se llame científica? ¿Se puede trabajar científicamente en psicoanálisis? En fin, podrían hacerse muchas otras preguntas al respecto; empero, de lo que se trata es de saber si el psicoanálisis, como un saber bien constituido, puede o no elevarse a la condición de un programa de investigación científica.
De acusados a acusadores: una historia de los Consejos de Guerra Verbales en Colombia, 1969 - 1982
Authors:   Universidad de Antioquia, Hincapié Rojas Sebastián
Published: September 2021

La discusión sobre el delito político parece nunca haber cesado a lo largo de la historia de nuestra nación. La guerra y la paz han contribuido, de maneras diferentes, a que en todos los periodos se discuta con pasión sobre su significado. En tiempos de guerra los presos se reivindican como delincuentes políticos y rechazan las acusaciones que los ubica como delincuentes comunes, terroristas o narcotraficantes; en los tiempos de paz, las palabras amnistía, indulto y, en estos últimos años, justicia transicional, comienzan a aparecer reiteradamente en los discursos de políticos, guerrilleros, militares y líderes sociales. La coyuntura actual sobre la Jurisdicción Especial para la Paz (jep) ha traído, nuevamente, la discusión sobre el delito político: los militares retirados se han atrincherado en sus escritorios y han criticado la amplia conexidad que pretende dársele al delito político; los guerrilleros han asegurado que es necesaria pues todos sus actos han perseguido el fin último de la rebelión, mientras el gobierno ha dejado en manos de la Corte Constitucional un pronunciamiento de fondo sobre el tema. La importancia que ha tenido el delito político en Colombia ha sido señalada constantemente para resaltar el rol que ha cumplido en la solución de los conflictos armados desde el siglo xix. No obstante, se han hecho pocos esfuerzos para comprender el rol que jugaron los actores políticos en la definición de un concepto que permanece lejos de tener un significado unívoco.
Desenfrenada lujuria. Una historia de la sodomía a finales del periodo colonial
Authors:   Universidad de Antioquia, Bedoya Molina Pablo
Published: September 2021

Si bien este libro parte del análisis de realidades localizadas en el Nuevo Reino de Granada a finales del siglo xviii y principios del xix, propone un análisis genealógico de la heteronormatividad que aporta a la comprensión del surgimiento, desarrollo e implantación de la heterosexualidad obligatoria como un sistema mundo que ha colonizado y violentado, a veces hasta su exterminio, otras posibilidades de amar y vivir juntos. Esta historia busca ofrecer además una interpretación histórica de la institucionalización de la homofobia en Occidente, de su implantación violenta en América y de los mecanismos de control del cuerpo, el deseo y la sexualidad a los que dio lugar en la sociedad de finales del periodo colonial. De igual forma, busca mostrar las experiencias de personas que, en medio de la represión, idearon formas de agenciarse los placeres, ensanchando así los límites de la heteronormatividad.
Michel Maffesoli: Un sociólogo posmoderno
Authors:   Universidad de Antioquia, Vélez Vélez Marco Antonio
Published: September 2021

Michel Maffesoli: un sociólogo posmoderno busca un acercamiento a la obra de este autor francés pretendiendo mostrar partes esenciales de su pensamiento sobre la posmodernidad. El debate que propone en términos de lo posmoderno de la sociedad de hoy no está ni mucho menos superado, según lo plantean aquellos que asumieron la discusión posmodernista como una moda intelectual más. Algunos pensaban que el concepto designaba la lógica cultural del capitalismo tardío, y no, como piensa Maffesoli, una transición epocal fundamental. En el mundo actual pocos sostienen ya el concepto de lo posmoderno. Sin embargo, Maffesoli considera su pertinencia aun hoy. Según él, podría mostrarse –que no demostrarse– el carácter del cambio de época. Este libro presenta a Maffesoli desde su ontología posmoderna: asumiendo que la modernidad ha tenido su propia manera de pensar el ser, que ahora se transforma en ontogénesis; desde su epistemología, centrada en la referencia a un conocimiento ordinario que posibilita un acercamiento no conceptual a la realidad; desde su visión del poder posmoderno, como desafección y aparente apatía; su visión sobre el inmoralismo ético, que no relativismo, como lo quiere la representación común de lo posmoderno. Y también desde su concepción de los imaginarios y las formas de simbolización, que hacen de la sociedad posmoderna un “mundo de los simulacros”.
Las Ciencias Sociales y Humanas en la Universidad de Antioquia. Avatares históricos y epistemológicos
Authors:   Universidad de Antioquia, Arcila Aristizábal Zoraida
Published: September 2021

Nuevos espacios para la institucionalización de las ciencias sociales se abrieron en el siglo xx en Colombia. La incorporación a la economía mundial generó modos de producción distintos y un nuevo dinamismo que se transmitió a la sociedad. El patrón social predominante se alteró con el incremento del volumen de trabajadores asalariados y con la formación de las clases medias urbanas, que en la segunda mitad de la centuria habrán de convertirse en la gran cantera para el reclutamiento de intelectuales. Aspectos como el crecimiento urbano, la industrialización y el desarrollo del capitalismo determinaron la necesidad de establecer programas académicos sociales y humanísticos para conocer y entender el proceso de transformación social que se hacía visible. ¿Cuáles fueron las condiciones generales y específicas de la emergencia de una nueva categoría de productores culturales alrededor de la Universidad de Antioquia?, ¿Respondieron los intelectuales a una necesidad específica política y/o institucional?, ¿En qué contexto tuvo lugar esta renovación intelectual y quiénes formaron parte de esa nueva élite?, ¿Se constituyeron las ciencias sociales bajo el liderazgo específico de un personaje, teoría o financiador individuales?
