Analysis and optimization of mechanical properties of recycled concrete based on aggregate characteristics
Authors: Bian Jiangwei , Zhang Wenbing , Shen Zhenzhong , Li Song , Chen Zhanglan
Published: September 2021

The most significant difference between recycled and natural concretes lies in aggregates. The performance of recycled coarse aggregates directly affects the characteristics of recycled concrete. Therefore, an in-depth study of aggregate characteristics is of great significance for improving the quality of recycled concrete. Based on the coarse aggregate content, maximum aggregate size, and aggregate shape, this study uses experiments, theoretical analysis, and numerical simulation to reveal the impact of aggregate characteristics on the mechanical properties of recycled concrete. In this study, we selected the coarse aggregate content, maximum aggregate size, and the aggregate shape as design variables to establish the regression equations of the peak stress and elastic modulus of recycled concrete using the response surface methodology. The results showed that the peak stress and elastic modulus of recycled concrete reach the best when the coarse aggregate content is 45%, the maximum coarse aggregate size is 16 mm, and the regular round coarse aggregates occupy 75%. Such results provide a theoretical basis for the resource utilization and engineering design of recycled aggregates.
Comment visualiser l’évolution historique des polysémies lexicales : l’itinéraire sémantique de terre et monde
Authors: François Jacques
Published: September 2021

There are two competing approaches to the change of lexical meaning: the individualizing approach, which focuses on the emergence of each particular meaning in a vocable, and the holistic one, which aims to account for the fluctuations, i.e. the expansion, stabilization and contraction of the range of its meanings. The individualizing approach remains dominant until today, although Arsène Darmesteter paved the way for the holistic approach as early as 1887. The purpose of this article is to extract part of the content of the TLF(i)’s historical records in order to build a diachronic semasiological database that can be converted into a series of trees symbolizing the fluctuations of the polysemy of an item century by century. The study is illustrated by exploring the evolutionary polysemy of the verb prévenir and the nouns terre and monde and results in highlighting the period of “coincidence” between the respective polysemies of these two nouns.
Las misteriosas /r/ de los adverbios en -mentedel español medieval
Authors: Company Company Concepción
Published: September 2021

The aim of this paper is to analyze the affix ‑m(i)entreof modal adverbs in Medieval Spanish, e.g.fuertemientre. The hypothesis is that the non-etymological, epentheticrmay be analyzed from a phonological perspective only, without grammatical or lexical explanations. The paper first reviews the three traditional explanations for the non-etymologicalrin modal adverbs, especially the analogical one, which poses that therof these adverbs is an analogy from the etymologicalrof the temporal adverbm(i)entre. The paper shows the weakness of these traditional analyses. The paper then presents an alternative analysis on phonological basis, which has greater parsimony than traditional explanations, adding typological evidence outside the grammatical field of modal adverbs, and showing that a non-etymologicalrappeared in many Spanish words, and in other Romance languages, in the same phonetic and syllabic contexts as the modal affix ‑m(i)entre. Finally, the paper proposes three causes for the loss of modal ‑m(i)entre: the weakening of intra-paradigmatic support from modal ‑miente, a homonymic clash between modal ‑m(i)entreand temporalm(i)entre, and the generalization of the learned form ‑mente. The paper places the diachronic loss of the modal affix withrin a theoretical frame of multicausality.

Published: September 2021

A crise gerada pelo novo coronavírus traz preocupações cada vez maiores entre as nações de todos os continentes e já altera profundamente as relações políticas e econômicas em escala global. Os impactos causados pela pandemia do coronavírus têm feito com que os países revejam as suas políticas publicas e levantem questionamentos sobre o sistema capitalista enquanto sistema social predominante. Há um reposicionamento de alguns Estados no sentido de adotar um modelo social, político e econômico  que garanta a todos os cidadãos padrões mínimos de saúde e seguridade social. Destarte, o presente artigo tem como objetivo apontar a importância do Estado de Bem-estar Social, seus benefícios em relação às políticas públicas, como é o caso do serviço de saúde pública. Nesse artigo, partimos do pressuposto de que a pandemia gerada pelo coronavírus expõe a fragilidade do modelo neoliberal brasileiro na contenção da crise, uma vez que esse modelo preconiza uma drástica redução do papel do estado na economia favorecendo o setor privado. Com o objetivo de abrir caminho para uma reflexão acerca desta problemática tomaremos como base o materialismo dialético que propõe busca pela explicação dos fenômenos da realidade a partir de condições estritamente concretas. O artigo foi desenvolvido a partir de pesquisa bibliográfica com abordagem qualitativa.
Moldova’s Thirty-Year Search for Independence
Authors: Negură Petru
Published: September 2021

Unlike in the Baltics, support for independence in Moldova was relatively low among the political elites and the general population when the Soviet Union collapsed. In the 1990s, the political parties in power pursued an incoherent program, as governments swung between reformist and conservative agendas. Economic crises and systemic corruption depleted citizens’ trust in politicians and state institutions. This low institutional trust has hampered governance at all levels, and primarily in crises such as the COVID-19 pandemic.
A Picture of a Good Death
Authors: Zaremba Cheyenne
Published: September 2021

In the early 19th century, the invention of the camera introduced a whole new way to capture and represent the body in death. Postmortem photography created a picture of the body that depicted death as poised, peaceful, and overwhelmingly white. This essay references postmortem photography and examples of racial injustice to exemplify the ways raced bodies are represented in images of death. Through the performance of three scenes, I explore the principle of a good death as a privilege historically withheld from Black Americans.
Speaking of a Good Death in the Language of Art
Authors: Brown Tracy T.
Published: September 2021

What is a good death and who deserves the experience? To answer this question, I decided to respond in the language in which I am most fluent. The language of art. The images here are a small portion of a body of work built from more than a decade spent photographing memorials and memorial spaces in an effort to document, interrogate, understand, and celebrate the universe’s second most unifying experience. Death. One hundred percent of all that is born…must die. My body of work focuses on Afro-Diasporic traditions and practices, but the themes illustrated are universal. In this visual conversation, a good death involves simple yet heartfelt experiences such as peace, comfort, space for tradition, celebration, and above all else…dignity.

In this exploration of life as the parent of a seriously ill hospitalized child, the researcher reflects on her participants’ and her own collective experiences and frustrations in the form of poetry.
Methodology of the Repressed in Faculty Hiring
Authors: Conlisk Gallegos Liliana
Published: September 2021

This essay documents forms in which repressed supremacy—with the purpose to ultimately push out and exclude people of color professors—is enacted. My endurance within toxic spaces is the result of channeling Tlazolteotl and putting my Coyolxauhqui together, referring to the act of constantly reinventing myself by turning excrement into life and rejoining the pieces of my experience. I also share a successful teaching, research, and service agenda of resistance that fulfills requirements as it is simultaneously defiant. By referring to covert acts of violence as the methodology of the repressed, my goal is to expose and promote their collective eradication.
Identification of proAKAP4 concentration variations in dromedary sperm and their correlation with monthly semen parameters
Authors: Malo Clara , Carracedo Sara , Delehedde Maryse , Sergeant Nicolas , Skidmore Julian Alexandra
Published: September 2021

ProAKAP4 is synthetized as a precursor polypeptide that must be converted into mature AKAP4 in living spermatozoa and is considered as a functional marker of spermatozoa. The gene is well-conserved in mammals although uncharacterized in Camelidae. In the present study, we investigate the expression metabolism of proAKAP4 and AKAP4 proteins and evaluate their seasonal dynamics relative to semen quality in dromedary camels. Semen parameters including volume and viscosity and characteristics of sperm including concentration, total production, total and progressive motility, vitality, acrosome integrity and morphological abnormalities were assessed in semen samples collected weekly from six camels during the rutting season, from November to April. Only total sperm production varied, peaking in January. Both the precursor proAKAP4 and AKAP4 proteins were investigated and shown to express biochemical properties similar to those described in other mammals. ProAKAP4 concentrations expressed in ng/10 million spermatozoa as assayed using a specific ELISA showed a strong positive correlation with ejaculate volume (P = 0.045), viscosity (P < 0.001) and sperm total motility (P = 0.049). Furthermore, their concentrations exhibited clear seasonal variations in camel semen. In conclusion, the assessment of proAKAP4 concentrations in camel sperm provides a novel parameter to assess sperm quality. Further studies should be performed to investigate proAKAP4 concentrations relative to fertility in Camelidae that may help to define the right time for mating and semen collection and increase the success of breeding programs.

Lay summary

Breeding related to the seasons/time of year in the camel has been reported in several studies. A better knowledge of semen quality during the breeding season would assist in determining the best period for mating in camels. However, conventional sperm parameters are held to be unsatisfactory because they cannot predict breeding potential. ProAKAP4 a sperm-specific protein has been described as a functional marker of sperm and a key fertility marker in several species but has not been described in camels. Motility or membrane integrity parameters of semen collected throughout the breeding season and also the presence of proAKAP4 protein were investigated. ProAKAP4 was identified for the first time in camels and their concentrations exhibited clear seasonal variations in camel semen showing strong correlations with ejaculate volume and total motility and viscosity. Further studies should be performed to investigate proAKAP4 concentrations relative to fertility in camels to define the right time for mating and increase the success of breeding programs.
Diet-induced- and genetic-obesity differentially alters male germline histones
Authors: Deshpande Sharvari S S , Nemani Harishankar , Balasinor Nafisa H
Published: September 2021

Obesity, an established risk factor for male subfertility or infertility, is primarily due to genetic and environmental causes. Our earlier studies have shown differential effects of high-fat diet-induced- (DIO) and genetically inherited- (GIO) obesity on DNA methylation in male germline and its subsequent effect on fertility. Here, we hypothesized that the effects of DIO and GIO on histone modifications in male germline could also contribute to fertility defects. We observed that DIO affected both active (H3K4me3, H3ac, and H4ac) and repressive (H3K9me3 and H3K27me3) histone marks in testis and their cell types, whereas GIO solely altered acetylated histones. This correlated with the deregulation of histone-modifying enzymes in the testis of both obese groups. Further, we also observed a decrease in chromatin remodelers in the testis of the DIO group, which were increased in the GIO group. Besides, there was an increase in core histones and a decrease in histone marks along with protamine deficiency in spermatozoa of the DIO group, whereas only H3K4me3 levels were increased in spermatozoa of the GIO group. Moreover, we observed alterations in the expression and enrichment patterns of a few developmental genes harbored by the active histone mark in resorbed embryos and spermatozoa of DIO rats. Together these epigenetic defects in the male germline could alter sperm quality and cause fertility defects in these obese groups. Differential changes in two obese groups could also be attributed to differences in their pathophysiological variations. Our study highlights epigenetic differences between DIO and GIO in the male germline and their subsequent impact on male fertility.
Die Grenzen der Mikrofundierung von dynamischen Fähigkeiten

Published: September 2021

Die Mikrofundierung von dynamischen Fähigkeiten zählt zu den wichtigsten Herausforderungen in der strategischen Organisationsforschung. Um das aggregierte Fähigkeitskonstrukt besser greifbar zu machen, versuchen viele Autoren, dynamische Fähigkeiten auf individuelle Faktoren und Prozesse zu reduzieren. In diesem Beitrag wird diese Forschungspraxis aus dem Blickwinkel des methodologischen Individualismus kritisch reflektiert. Dabei wird gezeigt, dass der Mikrofundierung kollektiver Konstrukte tatsächlich harte Grenzen gesetzt sind.

A través de dos encuestas realizada en los años 2010 y 2018, diversas personas que trabajan en la arqueología experimental explicaron su visión de esta ciencia y describieron qué tipo de actividades relacionadas realizan. Se preguntó a universidades, sociedades, freelancers y museos. Diversas actividades adyacentes fueron comentadas, como por ejemplo la arqueo técnica que es la realización de reconstrucciones y experimentos en vivo. Después de algunas confusiones y ejemplos aclaradores, se comenta el futuro de la arqueología experimental como disciplina para el uso no únicamente científico sino también social.
Este artículo es solamente una pequeña aproximación a discusiones e investigaciones mucho más extensas sobre este campo de investigación. Lara Comis (miembro de EXARC), actualmente está realizando un Doctorado financiado por la IRC en la UCD (IE) explorando la Arqueología Experimental y los museos arqueológicos al aire libre. Su investigación se inició con la presente encuesta, la cual varios miembros de EXARC ya les será familiar, que trata sobre como la arqueología experimental es entendida. Su trabajo está promovido activamente por EXARC.
Este estudio cuenta con una gran cantidad de información recopilada pero, solo ha sido posible publicar una fracción de este material. La mayoría de los artículos publicados aparece solamente en la literatura gris o literatura poco convencional. Por este motivo, EXARC tomó la iniciativa de recopilar esta información a través de su Colección de arqueología experimental, la cual está disponible en experimentalarchaeology.net.

Utilização de um simulador computacional para o ensino do lançamento oblíquo à luz da Teoria da Aprendizagem Significativa
Authors: Krummenauer Wilson Leandro
Published: September 2021

Neste artigo, relatamos uma experiência de ensino bem-sucedida na qual utilizamos um simulador computacional da plataforma Phet para demonstrar o lançamento oblíquo em uma turma do 2.º ano do ensino médio, no componente curricular de Física, em uma escola privada na cidade de Novo Hamburgo, RS. Utilizamos o simulador como atividade inicial de lançamento deste conteúdo nuclear a partir da seguinte situação-problema: para qual ângulo o alcance em um lançamento oblíquo é máximo e para quais pares de ângulos, para uma mesma velocidade inicial de lançamento, o alcance é o mesmo? Os alunos, em duplas, variaram os seguintes parâmetros iniciais: velocidade inicial, ângulo de lançamento e objetos a serem lançados, com diferentes massas. A partir da variação destes fatores, os alunos puderam analisar a trajetória do movimento, os vetores velocidade e aceleração, bem como as componentes vetoriais, além de observar os fatores que interferem tanto na altura máxima quanto no alcance máximo horizontal. Ao final da atividade, aplicamos um questionário referente ao tópico abordado, tendo como resultado um aproveitamento próximo de 90% de respostas corretas.

Background and aims

Despite the inclusion of the Compulsive Sexual Behavior Disorder (CSBD) in the International Classification of Diseases, very little is known about the underlying affective and cognitive processes. To fill this gap, we compared CSBD subjects and Healthy-Controls (HC) across negative/positive valence, cognitive and sensorimotor systems, as proposed by the Research Domain Criteria framework.

Methods

74 heterosexual CSBD and 66 matched HC males were studied with 10 questionnaires and 8 behavioral tasks. Analyses were conducted with frequent and Bayesian statistics.

Results

CSBD individuals showed significantly higher (than HC) punishment sensitivity, anxiety, depression, compulsivity, and impulsivity symptoms. Frequentist statistical analysis revealed significant interaction between subject group and condition in Incentive Delay Task, concerning the strength of motivation and hedonic value of erotic rewards. Bayesian analysis produced evidence for the absence of group differences in Facial Discrimination Task, Risk-Ambiguity Task, and Learning Task. Also, Bayesian methods provided evidence for group differences in the Emotional Stroop Task and the Incentive Delay Task. Sexual Discounting Task, Attentional Network Task, and Stop Signal Task produced mixed results.

Conclusions

Higher punishment sensitivity and impulsivity among CSBD subjects, along with significant interaction between these groups and erotic vs. non-erotic reward processing is in line with previous findings on negative/positive valence alterations in CSBD patients. This result shows that there are similarities to substance and behavioral addictions. The absence of group differences and mixed results related to cognitive and sensorimotor systems raise concerns to what extent CSBD resembles a wide spectrum of impairments observed in disorders, and demand further research.
Effects of different water activities on the stability of carotenoids in puff-dried yellow peach powder during storage
Authors: Gonzalles Gorby , Geng Ningning , Luo Shuwei , Zhang Chenchen , Wu Caie , Li Dajing , Li Ying , Song Jiangfeng
Published: September 2021

The stability of carotenoids in puff-dried yellow peach powder during commercial storage under different water activity conditions was studied. The results showed that when the corresponding water activity was above 0.576, the loss of adsorbed water in yellow peach powder was closely related to the crystallinity of the amorphous sugar matrix. However, the adsorption isotherms confirmed by water absorption behavior, X-ray diffraction (XRD) pat-terns, and scanning electron microscopy did not clearly indicate this loss of adsorbed water. The content changes of individual carotenoids (lutein, zeaxanthin, β-cryptoxanthin, α-carotene, and β-carotene) during storage followed pseudo first-order kinetics, and the degradation of lutein and zeaxanthin occurred quickly over time. The stability of total carotenoids gradually increased when the water activity was less than 0.576, but the carotenoids degraded sharply when the water activity was between 0.753 and 0.843. The loss of carotenoids was related to the water absorption and crystallization of the sugar matrix in the powder.
TELLING in English, Norwegian and French: A three-way contrast
Authors: Egan Thomas
Published: September 2021

This paper presents the results of a study of double object constructions containing the cognate verbs English tell and Norwegian fortelle, based on data from the English–Norwegian Parallel Corpus. The results show that there is a certain degree of correspondence between the two verbs in constructions with nominal direct objects, with less mutual correspondence in constructions with finite clausal objects, very little correspondence in constructions with objects in the form of direct speech, and none whatsoever in the case of non-finite clausal objects, which only occur with tell. The paper then expands the topic to include tell predications in French. The data were retrieved from the Oslo Multilingual Corpus. It transpires that the form of French translations of Norwegian expressions are more similar, at least for some constructions, to the Norwegian originals than are their English counterparts.

Two-barred Crossbills (Loxia leucoptera) have cyclic irruptions to Norway, but are generally uncommon and breeding is rare. Here I analyse data on a large irruption occurring in 2019–20 to assess the magnitude of the irruption and the ecological niche of the species. The irruption lasted one year, starting in July 2019 and ending in June 2020. Total numbers reported by birdwatchers to the website of the National Biodiversity Information Centre in Norway were ca. 7,000 individuals. Breeding indications were reported from nearly 100 sites. Analyses of elevation of records indicated that birds were often seen at low elevations before the breeding season in February–June, but moved to higher elevations during the breeding season. In a focal study area in SE Norway, breeding season surveys along elevational gradients indicated that Two-barred Crossbills occurred at higher elevations, and often close to summits of hills, perhaps representing preferences for more open forest habitats. Two-barred Crossbills often co-occurred with other seed-eating bird species, but presence was more closely related to numbers of Common Redpoll (Acanthis flammea), than to Eurasian Siskin (Spinus spinus) or cogeneric Common Crossbill (L. curvirostra). Similarly, the Common Redpoll also increased strongly in abundance with elevation, whereas the other two species did so to a lesser degree. These data suggest that the Two-barred Crossbill favors montane forests during the breeding season, and thereby has a different niche than the Common Crossbill which is distributed more widely across all elevations.
Semântica de eventos no domínio nominal: diferenças e semelhanças entre nominalizações e nomes que denotam eventos
Authors: Resende Maurício , Basso Renato
Published: September 2021

Nomes que denotam eventos (NDEs), sem contraparte verbal, tais como cirurgia e terremoto, formam uma classe, em geral, deixada de lado na literatura sobre semântica de eventos no domínio nominal, em comparação com as nominalizações. Neste artigo, nosso objetivo é, depois de argumentar linguisticamente que NDEs, de fato, denotam eventos, fornecer uma explicação estrutural para essa característica, baseada nos postulados da Morfologia Distribuída (Halle & Marantz, 1993). Argumentaremos que há duas estruturas distintas que denotam eventos e que os NDEs colocam questões importantes para a semântica de eventos das línguas naturais.
Evaluating water and gas permeability of fiber-modified landfill clay-base liner
Authors: Amini Mehrnaz , Isfahani Hajar Share , Azhari Amin
Published: September 2021

Due to the progressive use of landfills and the challenges about their effect on their surrounding environment, the hydraulic and gas permeability of the landfill liners has always been a great concern for geotechnicians. Clay-based materials are usually used as the main material for landfill liners. Various additives are implemented to control the hydraulic and gas permeability of these clay liners under different climate conditions. The attempt of this research was to investigate the effect of using four types of geo-fibers, including ordinary and web polyester, polypropylene, and polyvinyl alcohol fibers, on reducing the hydraulic and gas permeability under wet and dry conditions. In this regard, two sets of water and gas permeability tests were performed for clay–fiber mixtures with 0.2, 0.4, and 0.6 weight percentages of fiber additives. The results showed an initial decrease and then a growth in the permeability coefficients by increasing the fiber dosages, resulting in an optimum percentage for each fiber type. Among the fibers used in this study, polyvinyl alcohol fiber with 0.2 weight per cent performed best by reducing the permeability coefficient by approximately 65% and 75% for hydraulic and gas permeability coefficients under wet and dry conditions.
Application of a critical state model to the Merriespruit tailings dam failure
Authors: Mánica Miguel A. , Arroyo Marcos , Gens Antonio , Monforte Lluis
Published: September 2021

The use of stress–deformation analyses to evaluate the characteristics of possible static liquefaction events is rapidly becoming the norm for tailings dams exposed to such risk. Ideally, those analyses should be based on constitutive models that incorporate the fundamental mechanics of the problem, are able to perform robustly in commercial numerical platforms and are simple to calibrate. A model that aims to fulfil that specification is proposed. The model is a new implementation of a previously proposed model based on critical state concepts that is able to represent static liquefaction. The model formulation is elaborated to show that all the required inputs can be related to familiar concepts such as the critical state line, the state parameter, the normalised undrained peak strength or the coefficient of earth pressure at rest. The methodology is illustrated by analysing the failure of the Merriespruit tailings dam, which occurred in South Africa in 1994 and was instrumental in the recognition of how widespread liquefaction risk might be in saturated tailings. Numerical analysis of the case showed how a large static liquefaction failure might have been triggered by a relatively small slope erosion caused by overtopping.

Considerar a personalidade dos usuários nos Sistemas de Recomendação pode proporcionar resultados mais relevantes. Neste estudo, foi analisado se, com os avanços na detecção da personalidade (inferência sem usar questionários), as abordagens de Filtragem Colaborativa baseadas em personalidade continuam melhorando a acurácia das abordagens tradicionais (baseadas essencialmente em ratings). Outrossim, foi analisado se há diferenças ao aplicar modelos distintos de personalidade. No experimento, foram considerados 1058 usuários do TripAdvisor e 10889 clientes da Amazon, com características de personalidade inferidas via IBM Watson Personality Insights. Os resultados indicaram a possibilidade de melhorar a acurácia ao empregar uma abordagem usando dados inferidos concernentes a algum dos modelos de personalidade analisados (Big Five, Needs e Values). Ademais, o modelo Values proporcionou resultados equivalentes ao Big Five (sem facetas); e, em termos gerais, não houve melhoria ao usar o Big Five incluindo dados das suas facetas (nem ao incluir dados dos outros modelos).

Blockchain (BC) es una forma de tecnología de contabilidad distribuida (DLT) que ha ganado una atención y adopción destacadas en los últimos años. BC reduce los riesgos a los que son propensos los sistemas centralizados, a través de la descentralización de datos. Sin embargo, existe el gran reto de introducir esta tecnología a la sociedad. El artículo presenta un marco de trabajo desarrollado para aplicación de tecnología BC en el ámbito de la educación. El marco está compuesto por un conjunto de pasos como referencia para elaborar aplicaciones descentralizadas (DApps), además, presenta la elección de herramientas utilizadas en diferentes propuestas de este ámbito. Por último, se desarrolla una arquitectura robusta que puede ser implementada en diferentes DApps. El marco se valida en el caso de certificación académica y la gestión de propiedad intelectual, que incluye beneficiados y un análisis del aporte de esta tecnología en cada ámbito. El marco permite entender de manera precisa el funcionamiento de la tecnología BC y su aporte en la educación, ayuda a realizar un seguimiento y asegura la inmutabilidad de cada elemento académico individual de una manera escalable, ayuda a reducir los niveles de riesgo, elimina varios fraudes y malas prácticas, potencia la transparencia, y también ayuda a aumentar las medidas de seguridad.

Authors: Torres Puentes Elizabeth
Published: September 2021

Objetivo. Este artículo presenta parte de los antecedentes de una investigación cuyo objetivo es analizar la trama narrativa de la vinculación y participación de niños en grupos armados colombianos en distintos periodos. Metodología. Se soporta en el análisis narrativo, por ello para el acopio de antecedentes se revisó la literatura académica que hace énfasis en el recorrido por la vinculación y participación de menores a partir de algunos relatos de niños que fueron reclutados en los grupos armados desde la Guerra de los Mil Días hasta los grupos paramilitares de los noventa. Resultados. Se reconoce que el fenómeno de la vinculación de niños no solo es consecuencia del conflicto, también es una consecuencia del abandono institucional a niveles social, económico y político de la infancia. Conclusión. En los relatos estudiados se identifican elementos temporales y espaciales que configuran la trama narrativa de cada una de las guerras vividas en Colombia.

La comunicación popular como escenario de praxis para el trabajo social comunitario.
Authors: Lasso Urbano Carlos
Published: September 2021

Objetivo. El presente artículo expone la importancia de la comunicación popular como estrategia ético-política e innovadora en el ejercicio profesional del trabajo social comunitario. Metodología. Su exposición se realiza desde dos momentos: primero, desde el abordaje conceptual e histórico de la misma, integrando categorías como trabajo, comunicación, alienación, identidad, conciencia y lo urbano-popular; segundo, se examina la relación de la comunicación popular con el trabajo comunitario, para lo cual se describen sus características, aportes, particularidades, formas de manifestación social, evidenciándose la necesidad que existe de integrar sus componentes teórico metodológicos a los planes de estudio de formación profesional. Resultados. Se presenta la manera en que puede utilizarse en el marco de las luchas sociales y en la ofensiva contra hegemónica que deviene de los sectores urbano-populares. Conclusión. Los dos momentos se constituyen en aspectos esenciales para comprender la comunicación popular como escenario de praxis del trabajo social comunitario.

Authors: Vivero Arriagada Luis
Published: September 2021

Objetivo. Buscar los puntos de encuentro entre las propuestas teóricas y prácticas de Antonio Gramsci y Paulo Freire e interpretarlos a la luz del actual contexto sociopolítico latinoamericano. Metodología. Se consideró una revisión y análisis interpretativo de las obras de Gramsci y de Freire y esta se articuló con los pensamientos de otros autores adscritos a la corriente del pensamiento crítico latinoamericano. Resultados. Los resultados del análisis interpretativo muestran que los planteamientos de Antonio Gramsci, fundamentalmente lo desarrollado en los cuadernos, tienen puntos de encuentros en la propuesta político-educativa de Paulo Freire. Conclusión. Se concluye que la perspectiva heterodoxa del marxismo gramsciano se manifiesta en el pensamiento y la propuesta político-pedagógica de Paulo Freire, con una concepción hegeliana humanista, expresada en la propuesta pedagógica, lo cual se sintetiza en la praxis para la transformación y la liberación.

Authors: Burbano Zapata Mayra Alejandra
Published: September 2021

Objetivo. Presentar una aproximación a la lectura de las luchas por la memoria desarrolladas nacionalmente entre 2013 y 2017. Metodología. Este análisis es resultado del abordaje interpretativo de artículos de prensa, declaraciones en medios de comunicación, documentos oficiales y comunicados de los actores visibles en el escenario de justicia transicional. Resultado. Aquí el abordaje de discusiones teóricas, propias del campo de trabajos sobre la memoria, permite leer las actuaciones de actores estatales y organizaciones políticas y sociales en términos de disputas políticas. Conclusión. Se concluye que en los últimos años estas luchas han tenido diferentes coyunturas de activación en las que pueden observarse las discusiones y estrategias desarrolladas en relación con los sentidos de la reconstrucción de memoria para posicionar interpretaciones del pasado y para controlar los espacios institucionales dispuestos para la construcción y divulgación de narrativas sobre lo sucedido durante el conflicto armado colombiano.
Importancia de la diferenciación del enfoque diferencial étnico en el proceso de reparación en Bojayá, Chocó
Authors: Hinestroza-Ramírez Wanny Elizabeth
Published: September 2021

Objetivo. La aplicación del enfoque diferencial étnico en la reparación a víctimas negras tiene una trascendencia reivindicatoria de los derechos humanos como grupo, al constituirse como un instrumento de reconocimiento de sus particularidades culturales. Este artículo tiene como objetivo hacer una reflexión crítica a la aplicación de los principios y directrices que orientan la reparación en el derecho internacional, estudiando de manera particular el caso de Bojayá. Metodología. Para tales fines, la metodología que se empleó fue la revisión documental, a través de análisis de datos secundarios (estadística), estudio de contenido de documentos, textos, normas, jurisprudencias y doctrina. Resultado. La ejecución de planes de reparación afros sin atender el enfoque diferencial étnico se queda corto para satisfacer sus necesidades de reparación. Conclusión. Se concluye que en Bojayá los impactos generados por la aplicación de los estándares internacionales de reparación son relativamente bajos.
