Authors: Rodríguez-Rodríguez Mónica del P.
Published: May 2020

Las instituciones de educación superior dentro de su responsabilidad están llamadas a confrontar la acción social de sus estudiantes y egresados con la pertinencia de los programas que ofrece. El objetivo del estudio logró establecer los aportes educativos, productivos y comunitarios de estudiantes del programa “Licenciatura en Producción Agropecuaria” de la Universidad de los Llanos en comunidades rurales intervenidas en el municipio de Restrepo, durante el periodo 2012- 2014 a partir de procesos de formación en seguridad alimentaria y educación ambiental orientados desde los cursos de Educación y Extensión Comunitaria, y la Práctica Profesional Docente. Como ruta de investigación se optó por la cualitativa vinculando elementos propios de la complementariedad, se priorizaron técnicas como la observación participante, la interacción con la población objeto de estudio, el diseño y aplicación de fichas de caracterización, entrevistas en profundidad, grupos focales y la construcción de una matriz DOFA para el análisis reflexivo de la información obtenida. Los resultados de la investigación ratifican algunas de las fortalezas del programa de Licenciatura en Producción Agropecuaria: la formación pedagógica y humanista de los futuros docentes es útil para afrontar procesos de formación en educación no formal, para contribuir al mejoramiento de la calidad de vida de las comunidades participantes, quienes implementaron procesos de producción limpia de alimentos, escenarios de conservación de ecosistemas naturales y el fortalecimiento de los lazos comunitarios en pro de su desarrollo. El estudio concluyó que cuando la práctica pedagógica es contextualizada se consolidan soluciones para la diversa población rural atendida, que se hizo evidente con la implementación técnica y sustentable de huertas caseras, la adecuación de senderos ecológicos para la promoción del manejo ambiental, la implementación de proyectos sostenibles de avicultura, cunicultura, producción de abonos orgánicos, la agroindustrialización de productos y la implementación per se de procesos de seguridad alimentaria.

World Health Organization (WHO) declared the COVID-19 outbreak a public health emergency of international concern. Mental health strategies implemented due to the coronavirus epidemic must include the assessment of mental health status of people in different subpopulations influenced by the COVID-19 outbreak, identifying persons who are at high risk of manifesting behavior disorders, suicide attempt, and aggression in aim of providing appropriate mental health care interventions for those in need. The target population of these mental health strategies is categorized in four different groups: the most vulnerable people with mental health problems, isolated people with symptoms of atypical acute respiratory infection, individuals who have been in close contact with the previous two categories, and people affected by the preventive and restrictive measures.
Optimal Performance Targets
Authors: Hu Peicong (Keri) , Li Yiwen , Ray Korok
Published: May 2020

We study a class of contracts that is becoming ever more common among executives, in which the manager earns a discrete bonus if performance clears an explicit threshold. These performance targets provide the firm with an additional instrument to resolve its moral hazard problem with its manager. The performance target can achieve first-best under risk neutrality, with a target precisely equal to the desired effort that the firm seeks to induce. The optimal bonus increases in risk. If the manager is sufficiently risk-averse, the firm will shade the optimal target below equilibrium effort to provide a form of insurance to the manager, outside of the standard reduction in the bonus.

Authors: Akimori Teruki , Nakamura Kentaro , Asahi Tsuyoshi , Wada Hiroyuki
Published: May 2020

Chloroaluminum phthalocyanine nanoparticles were successfully prepared by laser ablation in liquid, and the photoacoustic signal of the nanoparticles was measured. Chloroaluminum phthalocyanine powders were irradiated with nanosecond-pulsed laser (Nd:YAG, SHG) to prepare nanoparticles. The particle size of prepared nanoparticles decreased with the increase in laser fluence. Absorbance of prepared nanoparticles was increased with the increase in laser fluence. The ratio between two peaks would be changed because of crystal structure change by photothermal laser heating. The production yield from raw material powder to nanoparticle was 92.8% at a laser fluence of 300 mJ/cm2. The nanoparticle-dispersed solution was stable for 80 days. The photoacoustic signal intensity of prepared nanoparticles increased with the increase in laser fluence.
Demokratiparadokset
Authors: Torfing Jacob , Winsvold Marte
Published: May 2020

In this chapter we discuss what we have conceptualized as “the paradox of democracy”, pointing to the conflict between the idea of the sovereign people on one side, and the idea that democracies need representatives and political leaders, on the other. The chapter gives an overview of democratic arrangements that encourage direct participation, including arrangements that feed into and support and arrangements that challenge the representative system. Furthermore, the chapter provides examples of arrangements that actively and intentionally link together representation and direct participation. Lastly, we discuss how the tension between participatory practices and representative democracy can be solved. In a brief and subsequent chapter, a Norwegian Mayor reflects on the conflict between representation and direct participation.

Authors: Ezeador C. O. , Ejikeugwu P. C. , Ushie S. N. , Agbakoba N. R.
Published: May 2020

This study was aimed to isolate and identify Pseudomonas aeruginosa and to determine the prevalence rate of isolated P. aeruginosa in Hospitals in Onitsha. Isolates of P. aeruginosa were recovered from both clinical and environmental sources using Cetrimide agar, Blood agar, Mueller-Hinton agar and MacConkey agar.  All the inoculated plates were incubated at 37°C for 24-48 hours and growth was evaluated on these media. Isolates were identified on the basis of standard bacteriological methods like morphology, colonial characteristics, smell in culture, haemolysis, as well as pigment production on these media. All suspected isolates were further characterized and identified by many biochemical reactions. Results revealed that only 22 (18.3%) isolates were P. aeruginosa, while other 98 (81.7%) represented other bacterial genera. The 22 isolates included 19 (86.4%) environmental isolates and 3 (13.6%) clinical isolates. Pseudomonas aeruginosa was most commonly isolated from sink (13.6%), then mops and cleaning buckets (9.1%) and least from theatre bed, nasal swab, floor, disinfectant, ear and wound swab (4.5%). The pigment varied from bluish-green to yellowish-green with a grape-like odor. All isolates were Gram negative, produced β-hemolysis on blood agar and were motile. The biochemical tests showed all the isolates to be strongly positive for catalase, oxidase, citrate, and casein hydrolysis. The prevalence rate of P. aeruginosa is relatively high and its isolation from sources like sinks and theatre bed could be suggestive of the role of this pathogen in nosocomial infections.

Multiple Causes of Dementia as Engineered Senescence
Authors: Garrett Mario Dominic
Published: May 2020

All traumas—cranial, cardiovascular, hormone, viral, bacterial, fungi, parasites, misfolded protein, genetic, behavior, environmental and medication—affect the brain. This paper itemizes studies showing the many different causes of dementia including Alzheimer’s disease. Causes interact with each other, act sequentially by preparing the optimal conditions for its successor, initiate other diseases, allow for other traumas to accumulate and degrade protective features of the brain. Since such age-related cognitive impairment is not exclusively a human attribute there might be support for an evolutionary theory of dementia. Relying on theories of antagonistic pleiotropy and polymorphism, the brain has been designed to sequester trauma. Because of increased longevity, the short-term tactic of sequestering trauma becomes a long-term liability. We are engineered to sequester these insults until a tipping point is reached. Dementia is an evolutionary trade-off for longevity. We cannot cure dementia without understanding the overall biology of aging.

Published: May 2020

Iron deficiency (ID) is the most common widespread nutritional disorder in the world in both developing and developed countries and remains a leading cause of anemia mainly affecting children between the ages of 6 to 59 months. ID can be understood as a state in which there is insufficient total body iron to maintain normal physiologic functions and which can vary in intensity from mild forms to the most severe condition which is anemia. The prevalence of ID among children under the age of three years old is high, varying according to the regions of the world, between about 10% in the USA to 33% in African countries, South-East Asia and Eastern Mediterranean. In view of the importance of ID for human health, with its physical, emotional, social and economic repercussions, it is important to know all aspects related to this nutritional deficiency so that actions for prevention, identification and early treatment of those affected can be developed. This article briefly reviews the importance of iron for children's health, highlighting metabolism, clinical changes, diagnosis and measures that can solve or minimize this serious public health problem.

Urolithiasis is a well-known problem that stones could form in various parts of the urinary system and it is the most common disease of the urinary tract. The current study was planned to investigate the effect of radish juice on ethylene glycol (EG)-induced urolithiasis. Twenty-one rats randomly divided into three groups. The first group was the control group was received normal standard diet and drinking water and the second group represented the model group received 0.75% EG in drinking water ad libitum. The third group received radish juice (2 ml/kg of body weight) by gavage plus EG (0.75%) in drinking water ad libitum. The experiment was conducted for 28 days. The light microscope examination revealed a disturbed histological architecture of the kidney tissues, including dilated renal tubules, aggregation of infiltrated leukocytes inflammatory cells, and crystal deposition in the model group. The EG plus radish juice treated rats showed higher crystal density with improved renal tubule structure and alleviated inflammation. Both treated groups showed various biochemical alterations compared to control group, but the most interest biochemical result was the significant decrease of malondialdehyde, a lipid peroxidation marker, and in the radish plus EG group compared to the EG group. Scanning electron microscopy showed clear structural detail about calcium oxalate crystals in which radish-treated group showed higher crystal deposition and calcified tissue compared to EG group. The present study concluded that radish juice promotes stone deposition but exerted an antioxidant effect.

Racialized Social Class Pedagogical Praxis: Critical Compassion, Cariño, Respeto and Confianza
Authors: Jaime-Diaz Jesus
Published: May 2020

This article explores the ways in which high school teachers understand their students in relation to their own racialized social class backgrounds. It problematizes ethnic outsider inabilities to engage teaching philosophies and practices, which render teachers unable to create constructive dialogues with students that have been marginalized in the culture of schooling. Given classed, raced, and gendered past practices in education and their schooling trajectory, which have historically truncated their potential mobility, this study is mediated by racial social class positions, which veil issues that intersect with structural inequalities. As such, this case study explores teacher/student engagements, focusing on reproduction of consciousness as unrealized teacher/learner schooling interactions. It is framed in contradiction to normative teaching practices, problematizing the absences of critical pedagogy in instruction, as it suggests alternative venues from an empowered perspective.

Carthamus tinctorius leaves were extracted with methanol and distilled water. The extracts were evaluated for their potential free radical scavenging capacity using four different in vitro methods (DPPH, metal chelation, radical removal and hydrogen peroxide scavenging methods). The total phenolic content obtained for aqueous (112. 2±1.708 GAE mg/g) and for methanolic extract (89.66±2.00 GAE mg/g). In DPPH, IC50 values was found to be 176.66±2.08 and 278.33±1.52 and 310.33±1.52 for the ascorbic acid, aqueous and methanolic extract respectively. In superoxide radical scavenging IC50 values are 381.27±1.43, 544.42±2 and 606.78±3.02 µg/ml for the ascorbic acid, aqueous and methanolic extract respectively. In the metal chelating activity, IC50 values are 385.94±3.00, 337±1 and 487±0.984 µg/ml for the EDTA, aqueous extract and methanolic extract respectively. In hydrogen peroxide scavenging, IC50 values were 261±1, 278±3.52 and 370±1 µg/ml for the ascorbic acid, aqueous extract and methanolic leaf extract of Carthamus tinctorius respectively. The correlation suggests that phenolic compounds are responsible for the antioxidant activities of leaves.

Coronavirus illness 2019 (COVID-19) is an airways infection caused by the new coronavirus (SARS-CoV-2) which has been quickly disseminated all over the world, affecting to the general population including women in pregnancy time. As being a recent infection, the evidence that supports the best practices for the management of the infection during pregnancy is limited, and most of the questions have not been completely solved yet.
This publication offers general guidelines focused on decision-making people, managers, and health’s teams related to pregnant women attention and newborn babies during COVID-19 pandemic. Its purpose is to promote useful interventions to prevent new infections as well as prompt and adequate attention to avoid serious complications or deaths, trying to be adapted to the different contexts in which attention to expectant mothers is provided. Guidelines are set within a well-scientific evidence and available recommendations up to date.
SARS-CoV-2 diagnostic testing alternatives for Latin America
Authors: Santaella-Tenorio Julián
Published: May 2020

In the past four months SARS-CoV-2 has reached most countries in the world. Public health strategies based on widespread testing and proper isolation of positive cases have shown to be helpful to reduce local transmission of SARS-CoV-2. Confirmatory tests, that identify viral RNA, and screening serological tests that identify viral antigens or host antibodies against viral proteins are part of the tools that nations can use to fight infectious disease epidemics. Understanding how each test works can provide insights about their test characteristics and how they can be used for different clinical and public health goals. Testing is a key strategy to reduce viral transmission, not only for this epidemic, but also for others to come.
Learning from combination HIV prevention programmes to face COVID-19 emerging pandemic
Authors: Palacios Ricardo , Mathias Augusto
Published: May 2020

Before a vaccine against SARS-CoV-2 became available, several measures to control COVID-19 pandemic are necessary. Analogously, in the absence of an available vaccine, Combination HIV Prevention Programmes have consolidated a large experience of biomedical, behavioral and structural interventions suitable for several epidemiological settings. Adaptation of such experiences can organize mid-term and long-term responses to face COVID-19
Mathematical models and the coronavirus, COVID-19

Published: May 2020

Currently, there are several mathematical models that have been developed to understand the dynamics of COVID-19 infection. However, the difference in the sociocultural contexts between countries requires the specific adjustment of these estimates to each scenario. This article analyses the main elements used for the construction of models from epidemiological patterns, to describe the interaction, explain the dynamics of infection and recovery, and to predict possible scenarios that may arise with the introduction of public health measures such as social distancing and quarantines, specifically in the case of the pandemic unleashed by the new SARS-CoV-2/COVID-19 virus.
Comment: Mathematical models are highly relevant for making objective and effective decisions to control and eradicate the disease. These models used for COVID-19 have supported and will continue to provide information for the selection and implementation of programs and public policies that prevent associated complications, reduce the speed of the virus spread and minimize the occurrence of severe cases of the disease that may collapse health systems.

Nas negociações de crédito, o risco é um custo que está sempre presente e, portanto, precisa ser quantificado. Neste cenário, existem diversas ferramentas que se propõem à análise do crédito, algumas delas de ordem quantitativa. Neste sentido, esse artigo tem por objetivo propor um modelo capaz de prever a insolvência de empresas por meio da aplicação do modelo de redes neurais artificiais. O estudo é uma pesquisa exploratória de caráter quantitativo, aplicado à área financeira, utilizando-se o modelo tradicional e o modelo dinâmico de análise financeira. Com os resultados, obtiveram-se dois modelos: um contendo apenas as variáveis do modelo tradicional e outro com as variáveis do modelo tradicional e do modelo dinâmico de análise financeira. A comparação entre estes dois modelos de análise de crédito possibilitou verificar a contribuição das variáveis do modelo dinâmico para o modelo final. Os índices que mais contribuíram para acurácia do modelo proposto foram: Índice de Rentabilidade (X5) com 100% de exatidão; Índice de Estrutura de Capitais (X2) com 98,9% de acerto; e Índice do Modelo Dinâmico (X8) com 91% de precisão.Palavras-chave: Análise de balanços.

LEI DE NEWCOMB BENFORD E AUDITORIA CONTÁBIL: UMA REVISÃO SISTEMÁTICA DE LITERATURA
Authors: Orth Caroline De Oliveira , Michaelsen Anna Tamires , Lerner Arthur Frederico
Published: May 2020

Lei de Newcomb Benford - LNB, foi concebida pelo astrônomo e matemático Simon Newcomb, em 1881. Seus estudos demonstraram que a ocorrência de um número natural, de modo espontâneo ou aleatório, não se dava na proporção esperada de 1/9, mas segundo uma distribuição logarítmica. Desde então, esta lei vem sendo testada em muitas áreas do conhecimento. Em finanças corporativas, os estudiosos têm testado a lei para investigar fraudes em dados contábeis. Contudo, ainda não há consenso sobre a eficácia da LNB nesse âmbito. Assim, o objetivo deste artigo é identificar os argumentos favoráveis e contrários, bem como os métodos de pesquisa e os principais achados das pesquisas sobre a aplicação da LNB como ferramenta de auditoria. Para tanto, aplicou-se uma Revisão Sistemática de Literatura, seguindo os passos de Levy e Ellis (2006). Deste modo, além de informações sobre autoria, modelos utilizados pelos autores para suportar suas conclusões e seus principais achados, apresentam-se lacunas de pesquisa, e as implicações para o futuro da pesquisa são discutidas.Palavras-chave: Lei de Newcomb Benford.

His studies showed that the occurrence of a natural number, spontaneously or randomly, did not occur in the expected proportion of 1/9, but according to a logarithmic distribution. Since then, this law has been tested in many areas of knowledge. In corporate finance, scholars have tested the law to investigate fraud in accounting data. However, there is still no consensus on the effectiveness of LNB in this area. Thus, the objective of this article is to identify the arguments for and against, as well as the research methods and the main findings of research on the application of LNB as an audit tool. For that, a Systematic Literature Review was applied, following the steps of Levy and Ellis (2006). Thus, in addition to information on authorship, models used by the authors to support their conclusions and main findings, research gaps are presented, and the implications for the future of research are discussed.Keywords: Newcomb Benford’s law.
