Authors: Ana Patricia Hernández Bernal , Lucy Andrea Cely Torres , Luz Dary Angel
Published: February 2021

Uno de los aspectos que más interés despliega hoy en día en todos los ámbitos de la sociedad es el relacionado con el medio ambiente; este es de considerable importancia para cada uno de los sectores productivos y en especial, para aquellas industrias que requieren asumir nuevos retos de cara a un mundo globalizado que demanda nuevas estrategias competitivas. De allí que, la logística inversa, sea vista como una herramienta clave para la toma de decisiones en diversos procesos llevados a cabo a lo largo del ciclo productivo (desde el origen hasta la utilización), brindando alternativas para la generación de beneficios tanto económicos como aquellos que, en la relación industria-medio ambiente, promueven el mejoramiento de condiciones competitivas. Desde esta perpectiva se identifican las experiencias, las tendencias y las estrategias que a nivel mundial han centrado su mirada en el desarrollo y la implementacion de la logística inversa especificamente con los empaques de Tetra Pak, profundizando en la preocupación no solo de la responsabilidad ambiental sino tambien identificando cual ha sido la participación que el gobierno y las entidades reguladoras han tenido para implementar y desarrollar procesos de logística inversa en los envases de Tetra Pak desde los hogares hasta las organizaciones que los producen. En este sentido, con el proyecto no solo se pretende identificar el proceso ideal de logística inversa para la reutilización de envases de Tetra Pak en Colombia sino que se desea preparar el material desde los jardines infantiles para que este pueda seguir la cadena de abastecimiento inversa con el fin de que su recuperación y reutilización se pueda llevar a cabo de manera efectiva.

Formato de presentación de proyecto. El papel de la Responsabilidad social empresarial en el empleo juvenil de calidad en la pymes del sector servicios de la ciudad de Bogotá
Authors: Cristian Dario Castillo Robayo , Julián Francisco Figueroa Espinel , Luis Fernando Moreno
Published: February 2021

La propuesta se basa en un análisis del empleo de calidad para los jóvenes en el cual se observa la responsabilidad social de las empresas 1 como una herramienta para reducir el desempleo y la informalidad de los jóvenes, específicamente para pymes en el sector de servicios en la ciudad de Bogotá. A partir de dicho análisis, se elabora una recomendación de política pública partiendo de criterios de responsabilidad social empresarial, para la disminución del desempleo informal mediante la generación de empleo formal o la formalización de los empleos existentes, conectando la oferta y la demanda y dando cumplimiento a las normas de seguridad social, mediante el estudio de los incentivos de responsabilidad social. La metodología se basa en el análisis de la gran encuesta integrada de hogares (GEIH) que elabora el DANE, para determinar el comportamiento de la inserción laboral y el empleo formal en el país por características socioeconómicas, esto por el lado de la oferta de trabajo; por el lado de la demanda se analizara una muestra de Pymes del sector servicios de la ciudad de Bogota para determinar qué características cumplen de responsabilidad social empresarial según indicadores propios a partir de indicadores GRI y analizar los determinantes de la demanda de la empresa. El proyecto se realizara en dos etapas, la primera con el estudio de la inserción laboral y la segunda con el análisis de la calidad del empleo joven en estas empresas, partiendo de dos puntos de vista, el positivo con la inserción laboral e incentivos y el normativo con el empleo de calidad y sus incentivos.
Preparation and properties of magnetic cellulose fiber composites
Authors: Wu Wei-Bing , Jing Yi , Gong Mu-Rong , Zhou Xiao-Fan , Dai Hong-Qi
Published: February 2021

Magnetic cellulose fiber composites were prepared by a “vacuum-lumen-loading” method with polyethylenimine (PEI) as retention aid. The composites thus formed preserved the inherent properties of the cellulose fiber and gained the magnetically responsive properties of nanoparticles. Magnetic paper was further made from the composites. These materials were characterized by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, a vibrating sample magnetometer, and paper testers. There was a large amount of magnetic nanoparticles deposited on the exterior, in the pores, and especially in the lumen of fibers. Lumen loading of nanoparticles is favored by pulp beating, silica shell modification of magnetite, vacuum conditioning, and usage of PEI. The physical strength of paper was reduced to a certain extent because of unavoidable deposition of nanoparticles on the exterior of fibers, which could block the formation of hydrogen bonding between fibers. Our results show that both the cellulose fiber composites and the resulting paper possessed good superparamagnetism with tiny remnant magnetization and coercivity. These materials will allow the investigation of new concepts in paper making and packaging, security paper, and information storage.
Vegan Diet Advice Might Benefit Liver Enzymes in Nonalcoholic Fatty Liver Disease: an Open Observational Pilot Study
Authors: Chiarioni Giuseppe , Popa Stefan Lucian , Dalbeni Andrea , Senore Carlo , Leucuta Daniel Corneliu , Baroni Luciana , Fantin Alberto
Published: February 2021

Background and Aims: The Western diet is rich in saturated fats, refined sugars and meat consistent with a high-energy load and secondary risk of increased metabolic diseases including nonalcoholic fatty liver disease (NAFLD). However, no data are available on potential benefit of vegan diets in NAFLD and/or nonalcoholic steatohepatitis (NASH). We aimed to study prospectively the effect of a vegan diet, excluding all animal products on liver chemistry in a group of consecutive NAFLD patients.

Methods: This was a prospective, pilot study run on 40 consecutive patients affected by NAFLD. Eight subjects refused to join the study for poor diet palatability, leaving 32 patients (19 males, mean age 50 years), with abnormal measures of liver function who agreed to adhere to a vegan diet for six months. The caloric intake was tailored by the dietitian to obtain a weight loss ≥5% of body weight in overweight patients [body-mass index (BMI) ≥25] and ranged from 1500 Kcal to 1800 Kcal. Patients were contacted monthly by phone to reinforce diet and lifestyle advice and were seen at the gastrointestinal clinic when doubtful about diet advice.

Results: At six-month follow-up, 6 subjects did not attend the clinic leaving only 26 patients for data analysis. Initial anthropometric values were mean weight 78 kg (range 52-95), mean body mass index (BMI) 26.8 Kg/m2 (range 20.3-31.2). Liver function tests showed mean ALT value 99 U/L (SD±45), mean AST value 54 U/L (SD±44), mean GGT value 160 U/L (SD±122), pre-treatment. After six months mean body weight was 73 Kg (range 52-87), mean BMI was 25.2 Kg/m2 (range 20.3-29.7) (p<0.001 compared to baseline for both parameters). Liver enzymes improved to a mean of ALT value 36 U/L (SD±21), AST value 27 U/L (SD±10) and GGT value 55 U/L (SD±57), respectively (p<0.001 compared to baseline for all enzymes). Normalization of liver function tests as a whole was observed in 20/26 patients (76.9%). A loss of ≥ 5% of body weight was observed in 12 patients (46.1%), but it did not correlate with the normalization of liver function tests (p=0.5).

Conclusions: Our data provide preliminary evidence of improved liver enzymes in NAFLD patients with a strict vegan diet and although our study sample is limited, decreased body weight did not seem critical to the outcome.

Published: February 2021

Background and Aims: The 6-minute walk test (6MWT) is a measure of the overall functional capacity and is associated with the risk of mortality in patients with liver cirrhosis and in those listed for liver transplantation. Nevertheless, physical performance has not yet been established as a predictor of the risk of clinical decompensation in patients with cirrhosis. We aimed to determine the capacity of the 6MWT to predict the clinical decompensation in patients with cirrhosis after 1 year of follow-up.

Methods: This prospective cohort study included patients with compensated cirrhosis of several etiologies. All participants had stable clinical conditions for at least 6 months prior to baseline. At baseline, patients performed the 6MWT and were followed up for 1 year to detect the decompensation outcomes.

Results: A total of 55 participants completed the evaluation and follow-up. The mean age was 56.3±10.5 years, and 65% were men. Around 65.4% were classified as Child-Pugh class A. In the receiver operating characteristic analysis, a walking distance ≤ 401.8 m during the 6MWT was set as the threshold for predicting clinical decompensation with 64% sensitivity and 82% specificity. Kaplan-Meier curve analysis revealed that patients who covered a distance of < 401.8 m during the test had a decompensation-free outcome rate of 30% as compared to the rate of 75% of those who walked > 401.8 m (p<0.001).

Conclusions: The 6MWT was a significant predictor of clinical decompensation in patients with cirrhosis. A cutoff of 401.8 m was related to an increased risk of clinical decompensation in cirrhotic patients with a stable clinical condition at baseline. The 6MWT should be added to the clinical assessment of the cirrhotic population.
Socialization and social innovations in economic development
Authors:   State Institution ", Heyets Valeriy ,   Institute for Economics and Forecasting, NAS of Ukraine"
Published: February 2021

It is shown that economic development includes the subjective activity of people, which is conscious and is formed in the process of socialization that takes place because of the interiorization of social forms of life. The internal psychology of a person receives an outwardly expressed form through exteriorization, which, thanks to the accumulated internal potency, comes into contradiction with the surrounding social environment. The result of the solution of these contradictions is social innovations, which renew and intensify the vital activity of both individuals, individual collectives, and society as a whole. Social innovation is considered as the accumulation of intangible assets in the form of skills that are competitive and exclusive. On this basis, the author characterizes socialization in the economy through the process of socialization of capital, and socialization of the state and public organizations. Also, the article tackles the problems and the role of digitalization in the transformation of the individual socialization.
A Quality Improvement Initiative to Reduce Unnecessary Rapid Responses Using Early Warning Scores
Authors: Penney Scott W. , O’Hara-Wood Scarlett N. , McFarlan Lisa M. , Slaughter Robert P. , Cox Carla S. , Gibbons Amber N. , Sam Ashley E. , Matos Renée I.
Published: February 2021

OBJECTIVES:

The Pediatric Early Warning Score (PEWS) is an evidence-based tool that allows early collaborative assessment and intervention for a rapid response team (RRT) activation. The goal of our quality improvement initiative was to reduce the percentage of unnecessary RRT activations by 50% over 2 years without increasing PICU transfers or compromising patient safety and timely evaluation.

METHODS:

A PEWS system replaced preexisting vital signs–based pediatric RRT criteria and was modified through plan-do-study-act cycles. Unnecessary RRT activations, total RRT activation rate, transfers to the PICU, total clinical interventions performed per RRT, and missed RRT activation rate were compared between intervention periods. Likert scale surveys were administered to measure satisfaction with each modification.

RESULTS:

There was a significant decrease in the percentage of unnecessary RRT activations from 33% to 3.5% after the implementation of the PEWS and modified-PEWS systems (P < .05). The RRT activation rate decreased from 22.6 to 13.3 RRT activations per 1000 patient care days after implementation of the PEWS and modified-PEWS systems (P < .05), without changes in PICU transfer rates. Physicians reported that the PEWS system improved nursing communication and accuracy of RRT criteria (P < .05). Nursing reported that the PEWS system improved patient management and clinical autonomy (P < .05).

CONCLUSIONS:

The PEWS systems have been an effective means of identifying deteriorating pediatric patients and reducing unnecessary RRT activations. The new system fosters collaboration and communication at the bedside to prevent acute deterioration, perform timely interventions, and ultimately improve patient safety and outcomes.
INFLUENCE OF SUBSIDIES ON THE EFFICIENCY OF PRODUCTION IN SHEEP BREEDING (ON THE EXAMPLE OF SHEEP FARMS FROM SOUTH-WEST BULGARIA)
Authors: Momchilov Hristo , Pamukova Darina
Published: February 2021

The purpose of this study is to clarify the influence of subsidies on the efficiency of production in sheep breeding by analyzing the mechanism of functioning based on different types of farms in the southwest region of Bulgaria. Options have been identified that could lead to a positive economic result. Most attention is paid to the profitability of production when farms do not receive or receive subsidies from the state. Small farms (with up to 50 ewes) were strongly dependent on the subsidies for pastures. With subsidy, the profitability of costs and revenues was higher. In farms with 50 tо 99 ewes subsidies also played an important role for increasing the profitability of operations. In farms with more than 100 ewes, which also received the highest subsidies could not survive only from sales of produce, as in most of these farms, the profit was negative, e.g. they were at a loss, hence the negative profitability results.
RESEARCH OF THE RELATION "URBAN AGRICULTURE - RURAL ECONOMY
Authors: Blazheva V.
Published: February 2021

More and more companies are striving to provide fresh food production in the immediate vicinity of major cities, thus shortening the supply chain for the end user. According to FAO (Food and Agricultural Organisaton), about 800 million people worldwide cultivate different crops in and around cities, which means that 20% of the world's urban population is in one form or another occupied in urban agriculture (1). Rural areas make up half of Europe's territory and employ around 20% of the population. (2). Due to this reason, the attention is drawn to the contrast between the urban agriculture and the rural economy. The aim is to explore and reveal the "urban agriculture - rural economy" relation. The methods of the present study are scientific research methods: comparative analysis method, induction and deduction method, retrospective analysis and others; illustrative methods - tables, figures and others. In terms of expected outcomes, this article focuses on highlighting the social, economic and environmental aspects of the emergence of the correlation between urban agriculture and the rural economy. The final part focuses on the challenges of theurban agriculture and the rural economy.
THE NEED FOR STATE INTERVENTION IN THE ECONOMY AND IN PARTICULAR IN THE AGRICULTURAL SECTOR - ARGUMENTS FOR AND AGAINST
Authors: Stoyanova Darina
Published: February 2021

THE PURPOSE of the present research is to examine the main author's opinions regarding the state policy and its intervention in the economy and in particular in the agricultural sector, and on this basis to draw out, systematize and summarize the main directions and arguments for and against the intervention of the state in the economy. METHODS: Based on a literature review should be grouped the different opinions of the authors studied this problem. We should make a comparative analysis of the negative and positive aspects of state intervention on the economy and taking into account the specifics of the agricultural sector. RESULTS: As a result of the research are summarized and analyzed the main tendencies and opinions about the need for state intervention in the economy. CONCLUSIONS: From the analysis made in the study, there is no unambiguous vision in the economic literature regarding the need of state intervention in the economy and agricultural sector. Despite all the arguments that are drawn against the state support, the state through its policies and measures intervenes in the financial and credit markets. Factors have been put forward to support the need of state intervention to prevent market failures such as monopolization of production, imperfect competition and others. Highlighted are examples of highly developed countries where the mixed type of governance and adequate state intervention positively affect the economy.

The amygdala is a subcortical structure located bilaterally in the medial temporal lobes. This structure captures the attention of neuroscientists due to its role in emotion processing and learning. Animal studies indicate that groups of nuclei situated in different parts of the amygdala are components of distinct neural circuits underlying in a varied way emotional and cognitive processes. Some authors even argue that the amygdala is deemed a single unit only owing to nuclei groups located closely. Verifying such a hypothesis with regard to humans is very difficult as, until quite recently, there has been only one method of amygdala parcellation, based on post-mortem anatomical tissue analysis. However, in more recent years, several attempts have been made to parcellate the human amygdala on the basis of structural and functional connectivity with other areas of the brain using magnetic resonance imaging techniques. Results of analyses conducted until now are not congruent in respect of the number and localisation of the obtained amygdala parts. This may be a consequence of using different techniques (functional magnetic resonance imaging or diffusion tensor imaging), various acquisition parameters of scanner and distinct data analysis procedures, especially clustering algorithms. Future research should be focused on the development of the most reliable method for parcellation of the human amygdala to enable clear identification. This will allow one to learn more about the functional organisation of this structure in humans.

Introduction: Stroke is the most common form of central nervous system condition. An average of about 80 heart transplantations are performed in Poland yearly. A transplanted heart is prone to tachycardia. Early, complex post-stroke rehabilitation requires physical effort from the patient. Case report: We present a clinical case of a patient with left-sided hemiparesis after a haemorrhagic stroke and on immunosuppressive treatment after heart transplantation (2005). Methods: The outcomes of rehabilitation therapy were assessed based on the following scales: the Barthel Index, a modified Rankin Scale, the Rivermead Motor Index, the National Institutes of Health Stroke Scale, the Mini–Mental State Examination, and the Geriatric Depression Scale. Moreover, pre- and post-exercise heart rate monitoring was performed. Results: As a result of comprehensive rehabilitation treatment, functional status improvement was observed in all estimated scales. The highest change was reported for Barthel Index (50%) and National Institutes of Health Stroke Scale (30%). Heart rate was between 75 and 180 bpm. Conclusions: A patient with a history of heart transplantation shows good tolerance of physical exercise despite tachycardia. Early post-stroke rehabilitation significantly improves functional status.
Kinetic behavior of soluble Pectinex Ultra SP-L converting sucrose into fructo-oligosaccharides in batch and continuous fashion
Authors: Kovács Zoltán , Števek Juraj , Fikar Miroslav , Czermak Peter
Published: February 2021

The enzymatic conversion of sucrose to fructo-oligosaccharides (FOS) catalyzed by Pectinex Ultra SP-L, a commercial enzyme preparation from Aspergillus aculeatus, under free condition was studied. A mathematical analysis of the transfructosylation reactions was carried out to estimate the dynamic and steady-state performance of an enzyme membrane reactor (EMR) and to compare the continuous production scheme with the traditional batch process realized in stirred-tank reactor (STR). Kinetic parameters were identified simultaneously from a series of progress curves obtained from STR and EMR experimental runs. Model estimates appeared to fit well to experimental observations under the studied reaction conditions. Although conventional batch reactor outperforms EMR in terms of conversion, EMR compares favorably regarding productivity. The on-site industrial implementation of this technology might be attractive for food manufacturers aiming at utilizing a value-added sweetener mixture with prebiotic properties.

Regional Hip Hop and the Seoul Metropole
Authors: Farooqi Amos
Published: February 2021

Advances in music technologies over the past two and a half decades have effectively democratized the production and distribution of music and de-agglomerated music industries in much of the developed world. Artists are no longer pressured to move to centres of musical agglomeration to further their careers and can now grow their profile while remaining in their respective localities. However, this phenomenon has not taken hold in the Korean music industry, which remains hyper-agglomerated in Seoul. Hip hop artists in Korea continue to cluster in the capital, while hip hop scenes in provincial cities are in a constant state of flux. This study examines the current state of provincial hip hop scenes through the case study of Gwangju, where interviews with local hip hop artists and participant observation was conducted between 2016 and 2019. This article argues that the concentration of commercial, political, media and educational institutions in Seoul forces ambitions of moving to the capital city upon provincial youths from an early age and pushes a Seoul-centric culture that weakens their bonds to their respective localities. Artists and crews in provincial cities are thus largely ignored by local audiences forcing them to move to the capital in search of success, which in turn weakens their respective local scenes.

O déficit público e o crescimento da dívida mobiliária federal (1985-2018)
Authors: COUTO JOAQUIM MIGUEL , LIMA LUIS GUSTAVO ALVES , COUTO ANA CRISTINA LIMA
Published: February 2021

RESUMO O déficit das contas públicas é costumeiramente apontado como o principal responsável pelo aumento da dívida pública federal brasileira. No entanto, isto não é verdade. A análise realizada neste estudo, para o período de 1995 a 2018, demonstrou que o déficit nominal do Governo Central representou apenas uma parcela menor do crescimento da Dívida Pública Mobiliária Federal interna (DPMFi). Outros fatores, principalmente os relacionados às políticas monetária e cambial do Banco Central, explicam a maior parte do crescimento da DPMFi no período.
AVALIAÇÃO EDUCACIONAL NA ÁREA DA SAÚDE
Authors: Mezzaroba Leda
Published: February 2021

Resumo: O presente trabalho objetivou verificar, entre periódicos indexados e produção científica catalogada, a frequência de publicações que enfocaram a avaliação educacional na Área da Saúde, de 1981 a 1992. A metodologia empregada privilegiou na análise a categorização dos textos segundo gênero, tendência temática e distribuição por sub-área de concentração. Concluiu-se que a procura por cursos de pós-graduação é incipiente; a frequência de publicações sobre o assunto foi relativamente pequena no período levantado e restrita a publicações específicas sobre o Ensino Médico; na maioria dos artigos a temática esteve relacionada à avaliação de disciplinas, ao desempenho do aluno e à mensuração. Detectou-se, porém, um conhecimento em construção que parece buscar a transformação do ato avaliatório em processo contínuo e diagnóstico, indo além da simples classificação.

Published: February 2021

São imprescindíveis as discussões praxiológicas no desenvolvimento de uma educação crítico-emancipatória. Neste estudo, foram analisadas as dimensões da práxis criadora e reflexiva na elaboração de um Projeto Político Pedagógico (PPP) de uma escola pública, pautado na perspectiva educacional de Paulo Freire. Para isso, realizou-se um curso de formação de educadoras, envolvendo a comunidade local e escolar de um município no Sul da Bahia, com foco na obtenção e desenvolvimento de Temas Geardores. As informações, obtidas por meio de videogravações dos encontros com moradores e educadoras, foram analisadas mediante a Análise Textual Discursiva, com base nas categorias: a) A práxis reflexiva no processo de compreensão das demandas da comunidade do Iguape; b) A práxis criadora no trabalho coletivo de construção do PPP da Escola Padre Guiuseppe Bonomi. Destaca-se que a práxis reflexiva e a criadora são indissociáveis em um PPP humanizador, pois relacionam-se tanto ao desenvolvimento da consciência dos sujeitos da comunidade local e escolar, quanto à dialeticidade do trabalho coletivo entre escola e comunidade na superação de demandas locais.
Sustainable development factors governing the smart evolvement of developing countries

Published: February 2021

Urbanisation problems could be solved when cities adopt the smart city concept. However, the creation of smart cities without incorporating sustainable development principles from the onset could render the intended solutions nullified, due to the anticipated effect of an unsustainable smart city on the environment. The aim of this paper is to identify the key sustainable development factors of smart cities and the challenges of creating smart sustainable cities in developing countries. The study adopted positivism research philosophy using deductive approach and purposive sampling technique. Close-ended questionnaires were used, and 76 responses were retrieved. Cronbach alpha test, mean score ranking and relative importance index were employed to analyse the data in the study. The findings emphasise the key sustainable development factors of smart cities, such as improving recyclable and reusable water treatment systems and adopting renewable energy sources. Furthermore, the main challenging factors were identified, such as lack of preparedness on the side of government, and the financial inclusiveness of the creation of smart sustainable cities. The study provides insight into factors which must be considered to ensure the sustainability of smart cities, and barriers which must be understood when creating smart sustainable cities in developing countries.

Authors: K Breding , A Lindal , D Sagna , P-G Larsson
Published: February 2021

The effect of a novel treatment principle for bacterial vaginosis has been investigated in an open clinical study. 10 patients received a single dose while 20 patients received three applications every third day. The formulation is in the form of vaginal foam, containing lactic acid, hydrogen peroxide and an antimicrobial lipid. The intention of using the foam form for delivery is to avoid the creation of untreated areas, as is the case for other local formulations. Clinical signs, symptom and microbial effects have been studied using strict Amsel criteria and modified Hay/Ison for inclusion and modified Hay/Ison to monitor clinical efficacy pre- and post- menstruation. Therapeutic parameters as pH, malodor, abnormal discharge, itch and pain were monitored during the study. The microbiological was monitored by PCR being able to detect 6 pathogens and Lactobacilli.
Disorders of Sleep and Aggression Trait in Women Associated: What Underlies Staying “Woke”?
Authors: DK Hobgood
Published: February 2021

Narcolepsy is a sleep disorder where the patient falls asleep unwillingly. It is thought to be related to hyper functioning central sleep centers in the brain. Sleep apnea is a disorder of breathing disruption during sleep. Genes of the dopamine system have been implicated with high dopamine: norepinephrine ratio. Since dopamine has also been associated with personality traits, the hypothesis we studied herein was that patients with narcolepsy and sleep apnea would score low in catecholamine settings causing aggression trait. We found that narcolepsy and sleep apnea diagnoses showed significantly lower aggression trait using an online test. The conclusion is that narcolepsy and sleep apnea patients are not aggressive in personality, and since aggressiveness is related to sympathetic nervous system activity, this would be predictable given the role of sympathetic nervous system in wakefulness.

Touching Outward; Art-making at the seam where care meets risk.What it is to touch? If we think with, and take seriously a fluid ontology, can we recognise embodiment itself as fluid? Drenched with unknowing and drenched with sensation and made possible by movement, vibration and magnetism.This video article engages with the potentiality for research in marine sustainability to develop through poetic logics, visual, filmic, relational art practices that bring diverse communities into conversation, to ask; “How might we engage artistic processes to better understand actual and perceived risks to marine sustainability and facilitate community engagement, beyond the circulation of scientific publication?Touching Outward; Art-making at the seam where care meets risk presents two artistic maps, iterations of a single project that explores methods for engaging diverse publics to imagine, feel, consider and care about marine-related issues of risk which impact oceans and coastlines.These artistic maps explore institutional, social and cultural factors influencing coasts and oceans in Aotearoa New Zealand. Embodiment is at the heart of these collaborative projects. We think of how embodied experience folds through imagination to create potentials for unseating convention, perspective, actuality, reproducibility, common sense.Our transdisciplinary project was developed by four artist-researchers from diverse disciplinary backgrounds, each of us working beyond our conventional practices– a geographer, a performance maker, a visual artist, and a film maker. We are moving between philosophy, social science, pedagogy, ecology, performance, poetry, installation and film. The framework of weak theory provides a kind of permission to reach beyond the conventions of our disciplines, to make space for modes of embodied research that entangle abstract and material concepts through relational, artistic and pedagogical intentions.Throughout the process and development of this artistic research, we question where a body begins and ends, how the voice as a vibratile force touches through time and space, and how moving image as a body of textures and cuts might contribute to methods of weak theory (Wright, 2015) and transdisciplinary creative practice.

La investigación “Recurso educativo digital adaptativo El rescate del reino: Una experiencia didáctica adaptativa para el aprendizaje matemático” tuvo como objetivo determinar los aportes del recurso digital educativo adaptativo (REDA)- en la cualificación del pensamiento matemático en los estudiantes participantes. La investigación de corte mixto en el marco del diseño de investigación-acción buscó ahondar en las características de los procesos habituales de aprendizaje de las permutaciones sin repetición, siendo el contenido programático a abordar y probar, en su articulación con las tic, los aportes en la cualificación de los procesos lógico-matemáticos de los estudiantes. Los resultados obtenidos explican que la secuencia propuesta desde el storytelling del “Rescate del reino”, los escenarios e historias que involucra, el abordaje de las actividades desde el reconocimiento de los estilos de aprendizaje y la intervención pedagógica del profesor, son elementos que contribuyen al aprendizaje de los presaberes (subsunsores) y saberes necesarios asociados al estudio de las permutaciones sin repetición. Por otra parte, la estrategia constituyó un escenario novedoso para los estudiantes, al favorecer el aprendizaje, tal como indica Zapata (2012), cuando menciona que la inclusión de elementos como la presentación multimedia, los tutoriales en video, entre otros, motivan al estudiante en sus actividades de aprendizaje.
As concepções de professores colombianos sobre o currículo de química nas escolas de educação média de Bogotá
Authors: Vianna Nycollas , Ritter Jaqueline
Published: February 2021

No presente artigo estão apresentados resultados de uma dissertação de mestrado de um programa de Pós-Graduação em Educação em Ciências de uma universidade pública federal no sul do Brasil. A pesquisa visou conhecer as concepções de professores Colombianos em relação ao Currículo de Química que desenvolvem nas escolas de educação média. Utilizando-se a Análise Textual Discursiva reconheceu-se quatro categorias finais denominadas “atividades curriculares com experiências inovadoras”, “definições de currículo pelos docentes de Bogotá”, “o currículo e sua relação com o mercado de trabalho” e “a autonomia na construção teórica do Currículo”, sendo as duas últimas apresentadas nesse artigo duas categorias com proposições, que sustentam a concepção de currículo como artefato cultural, embora ainda persista a concepção de currículo como documento que rege o processo educacional. Alguns docentes declaram, também, certa preocupação de que o Currículo de Química deve preparar o estudante para o mercado de trabalho. Entende-se que para que o currículo seja compreendido como um artefato cultural é importante, que o docente sinta-se protagonista de todas as dimensões teórico-práticas de sua criação, proposição e desenvolvimento.

SARS-CoV-2 enters cells using its Spike protein, which is also the main target of neutralizing antibodies. Therefore, assays to measure how antibodies and sera affect Spike-mediated viral infection are important for studying immunity. Because SARS-CoV-2 is a biosafety-level-3 virus, one way to simplify such assays is to pseudotype biosafety-level-2 viral particles with Spike. Such pseudotyping has now been described for single-cycle lentiviral, retroviral and VSV particles, but the reagents and protocols are not widely available. Here we detail how to effectively pseudotype lentiviral particles with SARS-CoV-2 Spike and infect 293T cells engineered to express the SARS-CoV-2 receptor, ACE2. We also make all the key experimental reagents available in the BEI Resources repository of ATCC and the NIH. Furthermore, we demonstrate how these pseudotyped lentiviral particles can be used to measure the neutralizing activity of human sera or plasma against SARS-CoV-2 in convenient luciferase-based assays, thereby providing a valuable complement to ELISA-based methods that measure antibody binding rather than neutralization.
Impact of Covariates in Compositional Models and Simplicial Derivatives
Authors: Morais Joanna , Thomas-Agnan Christine
Published: February 2021

In the framework of Compositional Data Analysis, vectors carrying relative information, also called compositional vectors, can appear in regression models either as dependent or as explanatory variables. In some situations, they can be on both sides of the regression equation. Measuring the marginal impacts of covariates in these types of models is not straightforward since a change in one component of a closed composition automatically affects the rest of the composition.
Previous work by the authors has shown how to measure, compute and interpret these marginal impacts in the case of linear regression models with compositions on both sides of the equation. The resulting natural interpretation is in terms of an elasticity, a quantity commonly used in econometrics and marketing applications. They also demonstrate the link between these elasticities and simplicial derivatives.
The aim of this contribution is to extend these results to other situations, namely when the compositional vector is on a single side of the regression equation. In these cases, the marginal impact is related to a semi-elasticity and also linked to some simplicial derivative. Moreover we consider the possibility that a total variable is used as an explanatory variable, with several possible interpretations of this total and we derive the elasticity formulas in that case.

A peculiarity of the magnetization of a ferromagnet by an alternating field
Authors:   M.N. Miheev Institute of Metal Physics, Ural Branch of the Russian Academy of Sciences, Reutov Yu. Ya.
Published: February 2021

It has been experimentally established that the demagnetizing field of the magnetic poles formed at the ends of an open ferromagnetic cylinder decreases with increasing frequency of the magnetizing field due to a decrease in their size under the influence of the surface effect. For this reason, as the frequency of the magnetizing external field increases, the internal field in a ferromagnetic cylinder near the surface approaches it in amplitude. In addition, it has been found that the field on the surface of a ferromagnetic rod magnetized by an alternating field significantly exceeds the latter in strength with increasing frequency of this field.
Para além das disputas identitárias: uma análise crítica da Agenda 2030 da ONU e da política criminal contra a violência de gênero no Brasil
Authors: Borges Clara Maria Roman , Cabral Leonardo
Published: February 2021

Resumo: O artigo realiza uma leitura crítica da Agenda 2030 da ONU para o Desenvolvimento Sustentável a fim de compreender o papel do gênero no âmbito da Declaração e o discurso que ela representa desde o contexto de sua criação e implementação no Brasil. Considerando a participação dos feminismos brasileiros no âmbito internacional e sua visão sobre a violência de gênero, questiona-se qual o papel da política criminal na promoção da igualdade e se os marcos legais nacionais do combate à violência de gênero são compatíveis com os compromissos internacionais assumidos pelo Brasil. A problematização das categorias presentes no ODS 5, realizada a partir revisão teórico-narrativa dos estudos queer, desenvolvidos por Judith Butler, permite compreender que a concepção do sujeito universal mulher como alvo da proteção do discurso jurídico não serve para afastar os fatores estruturais da desigualdade de gênero. Para tanto, é necessário pensar uma postura pós-identitária transgressora frente ao discurso jurídico, propondo uma nova e realística perspectiva de gênero no sistema de justiça para enfrentar o problema com inclusão e efetividade.Palavras-chave: Agenda 2030 da ONU, desenvolvimento sustentável, violência de gênero, teoria queer, direito pós-identitário.Abstract: The article makes a critical reading of the UN's 2030 Agenda for Sustainable Development in order to understand the role of gender within the Declaration and the discourse that it represents since the moment of its creation and implementation in Brazil. Considering the participation of brazilian feminisms in the international context and their view on gender violence, it is questioned the role of criminal policy in promoting equality and whether the national legal frameworks to combat gender violence are compatible with the international commitments assumed by Brazil. The problematization of the categories present in the SDG 5, carried out from a theoretical-narrative review of the Queer studies, developed by Judith Butler, allows us to understand that the conception of the universal subject woman to be protected by the legal discourse does not serve to remove the structural factors of inequality of gender. A transgressive post-identity posture in the legal discourse is needed, proposing a new and realistic gender perspective in the justice system to address gender-based violence with inclusion and effectiveness.Keywords: UN's 2030 Agenda, sustainable development, gender-based violence, queer theory, post-identity law.
In-situ Fluid Injections to Achieve Bio-Stimulated Calcite Precipitation in Expansive Soils
Authors: Pathak Anish
Published: February 2021

Expansive soils undergo vast changes in volume when subject to change in water contents and cause damages to infrastructures across the world. Traditional methods of tackling the problem of expansive soils using cement or lime are environmentally unfriendly and expensive. Microbial Induced Calcite Precipitation (MICP) is a new method which uses bacteria in the soil to precipitate CaCO3 (calcite) and improve the engineering properties of soils. Various laboratory studies have shown that this method can be applied successfully to treat expansive soils, but the field application of the method have barely been studied.

To study the applicability of MICP in field, a protocol was developed to perform in-situ chemical injections through a borehole and tests were conducted in Marsing, Idaho. Multiple rounds of chemical injections were performed, and soil samples were monitored for calcite content and swelling potential changes. Results showed an increase in calcite precipitation and decrease in swelling potential of the soil with each round of chemical treatment.

Additional study to understand the influence distance of chemical injections in the soil were performed by injecting water into the soil and collecting moisture change data around the borehole. A finite element model was created in ABAQUS to establish the influence zone of the injections and verified against field data. The finite element model was then used to study the effects of pressure, permeability and sorption characteristics of soil in influence distance. Results suggest that, in soils with low permeabilities, such as in case of expansive soils, higher matric suction can result in greater influence distances over time. It was also seen that change in pressure of injection had minimal effect in influence distance. This suggests that it may be possible to implement MICP protocols in expansive soils by injecting solutions through boreholes at very low pressures and longer durations.
