Child Externalizing and Internalizing Behavior and Parental Well-Being During the COVID-19 Pandemic
Authors: Portnoy Jill , Bedoya AnaCristina , Wong Keri Ka-Yee
Published: September 2021

In this study we surveyed families’ experiences with parental depression, stress, relationship conflict, and child behavioral issues during six months of the COVID-19 pandemic through the COVID-19: Global Social Trust and Mental Health Study. The current analyses used data collected from online surveys completed by adults in 66 countries from April 17, 2020-July 14, 2020 (Wave I), followed by surveys six months later at Wave II (October 17, 2020-January 31, 2021). Analyses were limited to 175 adult parents who reported living with at least one child under 18 years old at Wave I. Parents reported on children’s level of externalizing and internalizing behavior at Wave I. At Wave II, parents completed self-reported measures of stress, depression, and inter-partner conflict. Child externalizing behavior at Wave I significantly predicted higher levels of parental stress and marginally predicted parental depression at Wave II, controlling for covariates. Child internalizing behavior at Wave I did not predict parental stress or depression, controlling for covariates. Neither child externalizing nor internalizing behavior predicted parental relationship conflict. The overall findings demonstrate that child behavior likely influenced parental stress and depression during the COVID-19 pandemic. Findings suggest that mental health interventions for children and parents may improve the family system during times of disaster.

Authors: Setiasih Setiasih , Abdurrahman Ahmad Mualif , Soetanto Hendrawan
Published: September 2021

Moringa leaf is a potential animal feed material because it has a complete nutrient content as well as many bioactive compounds. Among its bioactive compounds are phytosterols and isoflavones. This paper aims to describe the importance of moringa leaf as feed supplementation to improve rabbit reproductive performance. The bioactive compounds in moringa leaf  have an important role  to trigger  reproductive hormones.. Phytosterols have a chemical structure similar to that of cholesterol that can be used as precursors of steroid hormones (testosterone, estradiol and progesterone). Isoflavones are one  of the flavonoid compounds, also have  estrogenic activity and are able to bind with estrogen receptors i.e. ER-α and ER-β. Because of these bioactive compounds, moringa leaves are potential to  be utilized as feed supplements as aphrodisiac for bucks, stimulating estrous, and increasing litter size and milk production of does, reduce mortality and increase weaning weight and average daily gain of bunnies.

Published: September 2021

Rice bran is a feed ingredient as a result of the rice milling process which widely used as an energy source in the feed formulation in the chicken diet. Rice bran contains various nutrients such as oil, protein, carbohydrates (especially starch), beta-glucans, and pectins. Rice bran contains bioactive compounds that have positive effects on the chicken performance and health. Recently, rice bran’s bioactive compounds have been developed as a source of making functional feed. The objective of this study was to review the bioactive compounds in rice bran and their benefits in order to produce chicken’s functional feed. The results of the study showed that rice bran contains oryzanol as an important bioactive compound that has high antioxidant activity. Furthermore, other bioactive compound, lysolecithin,  has an ability to reduce cholesterol content in blood, meat and eggs of chicken. Besides, rice bran extract is reported to exert antibacterial activity and has  immunomodulator function. It was concluded that the bioactive compounds of rice bran is potential to be used as  a substance for making functional feed for chickens.
Processing Technologies of Lignocellulosic Biomass: Potentials and Constraints for Ruminant Feed Production
Authors: Ginting Simon Petrus
Published: September 2021

Lignocellulosic biomass (LCB) such as crop residues and agro-industrial wastes are renewable resources and available abundantly. It could play central role in sustainable feeding system of ruminant production. These materials are potential source of fiber to support optimum rumen function and energy supply. However, the LCB has important nutritional constraints that limit its utilization as feed for ruminants. This review is intended to discuss nutritional constraints of LCB as ruminant feed and the potentials and challenges of processes in upgrading the nutritional quality of LCB. The main polymer compounds in LCB are  cellulose (30 to 60% ), hemicellulose (20 to 40 %) and lignin (15-25%)  and its  inter linkages make the energy contained in the LCB is less extractable by the ruminant digestive system. Physical, chemical and biological processing technologies have been well known as  alternative means to upgrade the nutritive values of LCB. Recently, novel processing technologies of LCB such as ionic liquid, organosolv, sonication, and new screened rot white fungi (Ceriporiopsis subvermispora) and some older technologies  using alkaline and acids have been studied and developed particularly for the purpose of biofuel production in the bio refinery industry. Processing technologies have different properties in degrading the lignin, degrading and solubilizing the cellulose and hemicellulose that all relate to the nutritive quality of LCB. Advantages of processed LCB in ruminant animals were indicated by increase in diet digestibility, intake, rumen fermentation and gain. It is concluded that numerous processing technologies are available to upgrade the nutritional quality of LCB, but there are obstacles to use some of these techniques for wide application in ruminant production system.

Published: September 2021

An analysis was carried out and an assessment was taken to perform the parameters of the State Program of the Russian Federation «Socio-Economic Development of the Far Eastern Federal District». The quantitative indicators of institutional formats are shown in the absence of significant changes in macroeconomic and demographic dynamics. There is a decrease in the attractiveness of the Far East in the field of high incomes as a result of a reduction in real incomes of the population in most regions of the Far Eastern Federal District. The process of reducing the number of population is noted both by migration outflow and as a result of natural loss. It is concluded that one of the reasons for non-compliance with the basic program macroeconomic indicators is the vague formulation of target criteria

Vivienda, un asunto de sustentabilidad urbana en México
Authors: García-Espinosa Salvador , Zavala-Villagómez María de la Luz
Published: September 2021

En México, el 70 % de sus habitantes vive en una ciudad y la expansión de la mancha urbana se presenta mayoritariamente a través del uso habitacional; de ahí la importancia de presentar una revisión de las políticas de vivienda gubernamentales; particularmente, la denominada como de interés social —es decir, aquella que se edifica a partir de la intervención del Gobierno en el otorgamiento de financiamientos—. El objetivo es evidenciar que se han privilegiado aspectos inherentes al uso eficiente de energía, a través de incorporar elementos de ecotecnias y relegando a un segundo término aspectos de índole urbana como la movilidad, los servicios y los equipamientos, razón por la que resulta impostergable el fortalecimiento de la política habitacional con indicadores de índole urbana que permitan crear una sinergia en la que la edificación de vivienda contribuya a la sustentabilidad urbana de las ciudades mexicanas.

Authors: Campos-Gajardo Alicia , Harris-Diez Ronald , González-Erices Daniel
Published: September 2021

El Seguro Obligatorio de Enfermedades, Invalidez y Accidentes del Trabajo, a través de su instrumento operativo, la Caja del Seguro Obrero, fue una institución chilena destinada a resguardar los intereses de los trabajadores en el ámbito de la previsión, y que funcionó entre 1924 y 1952. En el transcurso del tiempo, la diversificación en el alcance de sus prestaciones y la superposición del proyecto político del gobierno de Pedro Aguirre Cerda posibilitaron la vinculación de la medicina social con la vivienda obrera, para un resguardo de los trabajadores, en tanto motor del cambio social. El artículo propone una lectura de la arquitectura desarrollada por la institución referida, considerando un enfoque biopolítico, con el objeto de contribuir a la diversificación de marcos conceptuales de la arquitectura del periodo. La metodología comprende la interpretación del ordenamiento y el programa de los conjuntos, bajo las ideas de control y aseguramiento de las actividades de los trabajadores y sus familias, aplicada a la arquitectura de dos casos de estudio: los edificios colectivos de Arica e Iquique, construidos ambos por la Caja del Seguro Obrero en la década de 1940.

Published: September 2021

Natural-scientific prose is characterized by a specific description of the natural world in which scientific information is fitted in the experience of nature and animal characters only partially or minimally anthropomorphized. The goal of this research is firstly to explore the presence and influence of foreign literary authors in the history of Croatian (childrenʼs) literature, who dedicated their literary work to this unique literary subgenre, such as a Danish journalist and writer Carl Ewald and an American-Canadian zoologist and literary author Ernest Thompson Seton. Furthermore, the aim of the paper was also to study the contribution of Croatian authors – Miroslav Hirtz, Zlatko Špoljar, Antica Juras-Ljubić and Vlatko Šarić – in this narrative form by methodologically relying on the insights of literary science and animal studies.
Фразеологизми с орнитонимском саставницом у српском језику
Authors: Штрбац Гордана
Published: September 2021

The subject of this paper is phraseology with the name of the bird in its lexical structure (such as crn kao gavran, držati se kao pokisli vrabac, zaplesti se kao pile u kučine, podmetnuti kukavičje jaje etc.). These units were analyzed in order to present the language picture of the animal world of Serbian speakers. The research is based on linguocultural approach to language ‒ Zykova’s conceptual theory of phraseology and culture (Зыкова, 2015). Attention is mostly paid to the problem of motivation of the observed phraseologisms and the phraseological semantic processes. There are several different types of information that motivate the creation of phraseology with the name of the bird as their lexical component: the appearance of the bird, its sound and behavior, as well as its symbolic value.

Authors: Hojsak Wiktoria
Published: September 2021

Przedmiotem badań są przymiotnikowe i przysłówkowe derywaty leksemu село w języku ukraińskim oraz ich polskie odpowiedniki. Za zasadnością podjęcia tematu przemawiają: duże prawdopodobieństwo wystąpienia interferencji leksykalnej w językach blisko spokrewnionych; fakt, iż na współczesny zakres znaczeniowy rozpatrywanych leksemów miały wpływ zmiany ewolucyjne w obu językach oraz sztucznie narzucone w czasach komunistycznych (np. likwidacja leksemów z rdzeniem ріль-, nadmierne używanie skrótowców) oraz to, że niektóre z rozpatrywanych derywatów wchodzą w skład wciąż kształtujących się terminów społeczno-politycznych (np. сільський голова). Badania mieszczą się w zakresie językoznawstwa kontrastywnego. Zastosowano metodę porównawczej analizy semantycznej oraz analizy definicyjnej pojęć. Celem badań było określenie podobieństw i różnic w polach znaczeniowych analizowanych leksemów oraz w ich funkcjonowaniu w różnych kontekstach i stylach. Udało się wyznaczyć polskie odpowiedniki semantyczne derywatów ukraińskich, wskazać homonimy/paronimy międzyjęzykowe, podobieństwa i różnice stylistyczne,określić potencjalne trudności w tłumaczeniu (zweryfikowane na drodze badań empirycznych), wskazaćpewne nieścisłości w słownikach.
SURŻYK I JEGO RECEPCJA WŚRÓD STUDENTÓW UKRAINISTYKI NA UNIWERSYTECIE WROCŁAWSKIM
Authors: Rysicz-Szafraniec Julia
Published: September 2021

Niniejszy artykuł poświęcony został badaniu percepcji ukraińsko-rosyjskiego surżyka głównie w opinii polskich studentów, uczących się języka ukraińskiego na Uniwersytecie Wrocławskim. Zastosowana metodologia opiera się na socjolingwistycznej analizie sondażu przeprowadzonego wśród wybranych respondentów. Odpowiedzi dotyczące pytania o odbiór surżyka wykazały ilościowo większy odsetek negatywnej wizji tego zjawiska, co tłumaczy się, między innymi, brakiem szeroko zakrojonej hybrydyzacji w polszczyźnie mówionej i wysokim statusem języka państwowego w społeczeństwie polskim. Wyniki badania wskazują, że w celu głębszego socjolingwistycznego opracowania surżyka i jego wpływu na sytuację językową w nowoczesnym państwie ukraińskim należy kontynuować badanie odbioru tego subkodu równieżw slawistycznych ośrodkach poza Ukrainą, co umożliwi postrzeganie analizowanego zjawiska z szerszej perspektywy.

Published: September 2021

The purity is accounted for one of the main characteristics of sugar beet juice in the sugar production process. In this regard, in the paper, the impact of slicing parameters including blade type, slicing angle from 0 to 90°, slicing thickness from 3 to 6 mm, and preheating duration from 3 to 15 min was studied on juice purity using Response Surface Methodology (RSM). The Genetic Algorithm (GA) technique was also employed to find the optimum values of variables to reach the highest juice purity. The results indicated that the quadratic model was the best model to predict juice purity. The Findings presented that as cossette thickness and slicing angle increased, the juice purity was improved. Optimization of the quadratic model by GA showed the best cossette thickness was 6 mm for both blades. The results of optimization indicated that 92.25 and 94.45% juice purities could be obtained from optimum conditions.
Detecting protagonists and antagonists in the voice quality of American cartoon characters: a quantitative LTAS-based analysis
Authors: Tong Ke Hui , Moisik Scott Reid
Published: September 2021

The voices of heroes and villains in cartoons contribute to their uniqueness and helps shape how we perceive them. However, not much research has looked at the acoustic properties of character voices and the possible contributions these have to cartoon character archetypes. We present a quantitative examination of how voice quality distinguishes between characters based on their alignment as either protagonists or antagonists, performing Principal Component Analysis (PCA) on the Long-term Average Spectra (LTAS) of concatenated passages of the speech of various characters obtained from four different animated cartoons. We then assessed if the categories of “protagonists” and “antagonists” (determined via an a priori classification) could be distinguished using a classification algorithm, and if so, what acoustic characteristics could help distinguish the two categories. The overall results support the idea that protagonists and antagonists can be distinguished by their voice qualities. Support Vector Machine (SVM) analysis yielded an average classification accuracy of 96% across the cartoons. Visualisation of the spectral traits constituting the difference did not yield consistent results but reveals a low-versus-high frequency energy dominance pattern segregating antagonists and protagonists. Future studies can look into how other variables might be confounded with voice quality in distinguishing between these categories.
Propositions pour une psychosémiologie historique du français : quelques réflexions à partir de l’histoire du verbe français
Authors: Soutet Olivier
Published: September 2021

While it is true that the linguistic theory of Gustave Guillaume (1883–1960) is generally designated under the name of psychomechanics because it postulates that the thought in the language action operates through a constantly repeated and formally homogeneous set of movements, which gives it its psychically systematic character, it does not ignore the semiological dimension of language, which also aims at a certain systematization. Hence a place for a psychosemiology, which this contribution aims to define and illustrate from examples taken in the morphological history of French.

Inter/Viewing from Afar
Authors: Korin Ezequiel
Published: September 2021

Since 2003, journalists in Venezuela have been censored by the government, either directly or indirectly, through legal and paralegal means. As such, they have learned to tread carefully between self-censorship and retaliation, greatly impacting the way journalism is practiced there. This evocative autoethnography explores the experience of a recent émigré of Venezuela to the United States interviewing journalists in his former home country. The emergence of elements that rearticulate the sense of belonging in the interviewer are used as touch points to a reality presumably left behind, but ultimately lying dormant, ready to resurface at a moment’s notice.

Revisiting the 5000-Year-Old Tally at Mnajdra, Malta
Authors: Agius George , Brown Read Lorraine , Ventura Frank
Published: September 2021

The pillars at the entrance of the inner apse of one of the cluster of Neolithic temples at Mnajdra, Malta display rows of drilled holes which have been interpreted as a tally of days. Furthermore, it has been proposed that the number of holes in the rows on the east pillar coincides well with a sequence of intervals between the heliacal rising of bright stars or star groups. Is this remarkable correspondence simply a chance occurrence, or do the drilled holes represent material evidence of deliberate time reckoning by means of heliacal star risings in the Neolithic age? This question has led to the statistical investigation described in this paper, which takes into account the heliacal risings of all stars of magnitude 2.0 or brighter visible from Malta 5000 years ago as well as the Pleiades and the Hyades star clusters, which attracted the attention of other ancient cultures. The paper presents and discusses the method used and the challenges involved in the investigation. The results show that with a tolerance of ±1 day for uncertainty in the calculated heliacal rise days, the probability of achieving an exact correspondence between a random ordering of the tally and a series of star rises is 0.0014. With a wider tolerance of ±2 days the probability is 0.011. The final section discusses the significance and implications of these results.
Children’s cooperation in a number activity in kindergarten
Authors: Schanke Tuva
Published: September 2021

Norwegian kindergartens organize school-preparation activities for five- and six-year-old children. Prior studies have mainly focused on the distribution and content of preparatory activities, whereas there is less research about children’s perspectives and contributions. Video data was collected in a Norwegian kindergarten over a seven-month period, and the paper analyses how children cooperate and use verbal, non-verbal and material resources in an outdoor activity focused on numbers and counting. The children share knowledge about numbers and the rules of the activity, and they show strong willingness to include each other in the activity. The main implication for practice is that children at this age are in possession of quite advanced cooperative skills and capable of managing a number activity.
‘Two’s company, three’s a crowd’
Authors: Houen Sandy , Danby Susan
Published: September 2021

This paper examines how young children mobilize interactional resources to position peers as neither fully included nor fully excluded in a preschool classroom. A single case of a video recording of three preschool-aged girls was analysed using conversation analysis. Two girls restricted access to a third girl and positioned her on the periphery in peer activity. The third girl’s entry into the activity was restricted through the other two’s claims of object ownership, limited physical access to objects, multi-modal practices that diverted attention away from the coveted objects, and assessments and sanctions around engagement with an object. The recurrent attempts to keep out the third girl were undertaken through partitioning. Findings highlight how children protect dyadic relationships.

Published: September 2021

Purpose – This paper aims to identify and classify the main barriers for adopting circular economy practices using the Analytic Hierarchy Process (AHP) method for prioritization. The proposed methodology evaluates the importance of different classes of barriers for adopting circular economy practices in a food company and metalworking company.Theoretical framework – This study was based on the current theory of barriers to adopt circular economy practices and multicriteria decision-making.Design/methodology/approach – The Analytic Hierarchy Process (AHP) method was used to assess and prioritize barriers for circular economy practices. Stability was ranked using a sensitivity analysis.Findings – The results indicate significant differences in the classification of barriers. While the food manufacturing company indicate that the main barriers are related to technical information, the metalworking company considered that barriers relating to financial and economic issues have more of an impact.Originality/value – The study contributes to providing insights so that managers have a greater perception of the main difficulties in adopting circular economy practices, in addition, the study also contributes to extending the application of multicriteria decision making methodologies to the circular economy and evaluating the relative importance of the barriers.Keywords - Circular Economy; Analytic Hierarchy Process; multicriteria analysis; barriers; sustainable development.
Relativizers as markers of grammatical complexity: A diachronic, cross-register study of English and German
Authors: Krielke Marie-Pauline
Published: September 2021

In this paper, we investigate grammatical complexity as a register feature of scientific English and German. Specifically, we carry out a diachronic comparison between general and scientific discourse in the two languages from the 17th to the 19th century, using relativizers as proxies for grammatical complexity. We ground our study in register theory (Halliday and Hasan, 1985), assuming that language use reflects contextual factors, which contribute to the formation of registers (Quirk et al., 1985; Biber et al., 1999; Teich et al., 2016). Our findings show a clear tendency towards grammatical simplification in scientific discourse in both languages with English spearheading the trend early on and German following later.
Eco-friendly activated carbon developed from rice hulls for chromium and iron ion removal
Authors: AbdelGhany Gaber S , Ebrahiem Ebrahiem Esmail , Mohamed Hamdy F M , Ali Gomaa A M , Shehata Nabila
Published: September 2021

Rice hulls, a harmful biowaste, were used to produce nanosized activated carbon (RHAC) by combustion and phosphoric acid treatment. The developed RHAC was characterised using various structural and morphological techniques (scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy and nitrogen (N2) adsorption). The prepared RHAC was used to remove heavy metal ions (iron (III) (Fe3+) and chromium (VI) (Cr6+)) by using the adsorption mechanism. Adsorption parameters, such as contact time, dose and initial concentration of the heavy metal ions, were investigated. Five adsorption models (two and three parameters) were studied. Also, the adsorption kinetics through the intraparticle diffusion model was applied. RHAC showed adsorption capacities of 47.00 and 45.00 mg/g for iron (III) and chromium (VI), respectively. The findings recommend using RHAC as a low-cost and eco-friendly adsorbent for metal ion removal and water-treatment applications.

Authors: Ukaigwe Sandra , Zhou Yun , Shaheen Mohamed , Liu Yang
Published: September 2021

The performance of a membrane aerated biofilm reactor (MABR) treating raw municipal wastewater primary effluent was optimized. The MABR performance was challenged by the gradual increase of the organics and ammonia surface loading rates with hydraulic retention times (HRT) of 10.7, 6.24, 4.0, 2.0 and 3.0 h. With organics and ammonia surface loading rates of 20 g total chemical oxygen demand m−2 d−1 and 3.32  gNH4 +-N m−2 d−1, respectively, the reactor achieved simultaneous organics, nitrogen and total nitrogen reductions of 98, 96 and 67%, respectively. Microbial analysis indicated the coexistence of nitrite oxidizing bacteria, ammonia oxidizing bacteria, aerobic denitrifying bacteria and other bacteria within the MABR biofilm, correlating to simultaneous nitrification, denitrification and organics within the reactor.

Due to the extension of cities and industries and population growth, environmental pollution has become noteworthy. Heavy metals are pollutants produced by industrial factories. Therefore, wastewater should be purified and treated, and returned to natural water circulation. This research investigated the removal of heavy metal zinc (Zn) at high concentrations in Esfarayen Steel Industrial Complex and the performance of the integrated system including activated carbon adsorption column (as pretreatment) and reverse osmosis membrane system under different operating conditions. The variable parameters are pH (4.5, 6.5, 7, and 9), pressure (5, 7, 9, and 11 bar), and zinc concentration (30, 50, and 70 mg/l) to obtain zinc removal efficiency, turbidity dissolved solids (TDS), electrocoagulation (EC), and turbidity (TU) at constant temperature and flow rate. The results show that the integrated system efficiency at 9 bar pressure and pH of 7.5 is optimal as to water outlet quality. The removal efficiencies are 98.1%, TDS; EC, 97.4%; Zinc, 100%; and TU, 95.3%, which is desirable. Moreover, system efficiency at a high concentration of zinc is evaluated. According to the results, the integrated system is resistant to probable shocks, high concentration and has desirable efficiency with all parameters almost above 90%.

Published: September 2021

Volatility modeling and forecasts are essential tools to all financial sectors. This paper focuses on weekly exchange rate returns of the FRW versus USD from 2012 until 2018 obtained from the National Bank of Rwanda. The aim of this paper is to formulate an appropriate GARCH model which fits the data. The GARCH(1,1) model has been selected after using required techniques of model selection.Parameters have been estimated using Least Squares method first and then validated using MCMC method. Once the chain of parameters are found, both visual inspection and basic statistics are computed and in this study, they have illustrated a good compatibility between simulation and observations. Diagnostic of convergence of the chains of parameters has been checked and ensured the model to beaccurate. The results obtained from the LSQ and MCMC methods have been compared and found to be almost similar. An agreement between the model solution and actual data is obtained and a forecast is done by concluding that the estimated values are almost similar to the real data. Hence, the identified model is accepted for forecasting and recommended for further applications.

Authors:   Universidade Nova de Lisboa Campus de Campolide, Bravo Jorge M. , Ayuso Mercedes ,   University of Barcelona
Published: September 2021

Neste artigo desenvolve-se um modelo de previsão da mortalidade específica por idade e da esperança de vida mediante combinação Bayesiana de modelos (Bayesian Model Ensemble). O procedimento envolve a selecção do subconjunto de modelos a usar e a determinação dos respectivos ponderadores. São ainda calculados intervalos de confiança para as variáveis de interesse usando uma metodologia assente em Bayesian credible prediction intervals considerando o risco de modelo. Os modelos são calibrados à população portuguesa desagregada por sexo usando informação estatística relativa ao período 1960-2018 e às idades no intervalo 60-125. São efectuadas previsões até 2050. Os resultados obtidos antecipam a continuação do aumento da esperança de vida por período e por coorte nas idades adultas registado nas últimas décadas e sinalizam a existência nos sistemas de protecção social de impostos/subsídios implícitos entre gerações que distorcem as decisões de consumo, de mercado de trabalho e de poupança e questionam a justiça intergeracional.

En los últimos años el uso de Kanban se ha popularizado e incrementado en la industria del software. Sin embargo, la falta de experiencia y la difícil formación de los nuevos practicantes limitan su adopción dentro de las organizaciones. Una alternativa para resolver este problema, es hacer uso de juegos serios como herramienta en la capacitación del capital humano, ya que impulsan un cambio en su actitud, motivación y compromiso. Sin embargo, al existir muchos juegos serios con este propósito dificulta la elección del más adecuado, si no se cuenta con la debida experiencia. Este artículo presenta una biblioteca de juegos serios para enseñar Kanban desarrollada con el propósito de ayudar a los entrenadores a seleccionar el juego serio que cumpla con sus objetivos de enseñanza. La biblioteca fue validada por un grupo de expertos en Kanban. Los resultados destacan que la biblioteca ayuda a centralizar la información de los juegos serios y facilita la selección de juegos adecuados a los objetivos de aprendizaje establecidos a entrenadores poco experimentados.

La Operación Cóndor y el terrorismo de estado
Authors: Torres Vásquez Henry
Published: September 2021

Objetivo. Analizar la realidad histórica de las actividades criminales efectuadas por integrantes de las fuerzas militares desde 1975 en algunos países de Suramérica. La persecución trasnacional a los presuntos terroristas, comunistas y en general disidentes de los diferentes gobiernos como generadores de inseguridad en la región, ocasionó que estos fueran desaparecidos, asesinados y torturados. Metodología. Este artículo hace parte de una investigación socio-jurídica, en la que se utilizó un método jurídico-doctrinal. Resultados. En la denominada “Operación Cóndor” como forma de alcanzar seguridad, degeneró en la comisión de crímenes que fueron cometidos utilizando el fenómeno del terrorismo de Estado, el cual subyace en las prácticas de terror realizadas en el continente con el apoyo de los EE.UU. Conclusión. Para eliminar estas prácticas es fundamental la intervención de tribunales internacionales de tal forma que se evite la impunidad frente a estos graves crímenes de naturaleza internacional.

La cuestión del método es uno de los problemas centrales (y más polémicos) de la teoría social –lo demuestra el esfuerzo de los clásicos de las ciencias sociales: no fue por casualidad que Durkheim (1975) se detuviese a la construcción de un método para la sociología y que Weber (1992, 2000), además de ocuparse de la conceptualización de las categorías sociológicas, escribió ampliamente sobre metodología. Por eso mismo, toda aproximación seria a tales ciencias implica un esfuerzo de clarificación metodológica (Fernandes, 1980). Y no es casual que siempre que han sido objeto de cuestionamiento, el debate metodológico estuvo en primer plano– así ocurrió, por ejemplo, cuando se tornó visible, en los años 1960-1970 la crisis de la sociología académica (Gouldner, 2000; Morin, 2005; Giddens, 1978) y así se volvió a verificar cuando, ya profundizada esta crisis, las ciencias sociales desarrollaron explícitamente la discusión sobre los “paradigmas” (Santos, 1989, 1995, 2000).
Política de la información, las ONG y los medios de comunicación en los conflictos por derechos humanos : un balance.
Authors: Antonio López Jairo
Published: September 2021

Objetivo. El presente artículo presenta una revisión crítica de la literatura académica que estudia la relación entre las ONG y los medios de comunicación en los conflictos por derechos humanos. Metodología. A partir de una revisión documental, a manera de balance de estado del arte, se clasifican y analizan los principales enfoques y tesis de la literatura. Resultados. Se argumenta que la literatura académica ha enfatizado en cómo la política de la información se constituye en un repertorio modular del activismo en defensa de los derechos humanos, pero mantiene un sesgo en el análisis de las dinámicas, organizaciones y medios internacionales. Conclusiones. Se plantea la necesidad de desarrollar una agenda de investigación que tenga en cuenta los procesos y relaciones entre las ONG y los medios de comunicación a nivel estatal, además de repensar dicha relación en contextos de grave violencia contra periodistas con el fin de explicar las posibilidades y límites de la política de la información.

Published: September 2021

ABSTRACT BACKGROUND: The aim of this study was to accurately establish the variability in the anatomy of the radius and ulna in the context of the design of an intramedullary nail for both bones METHODS: Forearm computed tomography scans were used to measure the specific internal and external anatomy of the radius and ulna in adult patients. Patients with fractures or dislocations involving either the radius and/or ulna were excluded RESULTS: A total of 97 scans, comprising 84% male and 16% female patients, were included. The mean radius length was 238.43±18.38 mm (95% CI 234.60-241.74 mm). The mean curvature was an arc with a radius of 561.43±93.49 mm (95% CI 543.09-580.78 mm). The smallest measurement of the canal width was 5.17 mm (95% CI 4.87-5.47 mm). The ulna showed a mean length of 259.90±19.88 mm (95% CI 255.89-263.91 mm). The smallest measurement of the canal width was 4.80±1.30 mm (95% CI 4.53-5.87 mm). The mean proximal shaft angle was 11.39±3.30° (95% CI 10.76-12.82° CONCLUSION: This computed tomography scan-based anthropomorphic study has identified novel anatomical features and associations of human forearm bones. This information will be used in the design and manufacture of anatomic intramedullary devices to better manage radius and ulna fractures or pathology Level of evidence: Level 4 Keywords: radius, ulna, anatomy, osteology, radius of curvature, intramedullary design
