Authors: Toma BO , Ofakunrin AOD , Diala UM , Kanhu P , Baba F , Shwe DD
Published: October 2021

Background: The majority of neonatal deaths occur in low and middle-income countries. Availability of qualified human resources along with maternal and child health services are essential to curb these deaths. The study objective was to determine the availability of human resources and services for newborn care in Primary Health Care facilities in Jos North Local Government Area.

Methods: This was a descriptive cross-sectional study conducted in Primary Health Care facilities offering immediate newborn care. A stratified sampling technique was used to select 67 and 60 healthcare workers in 30 public and 30 private facilities respectively. A structured questionnaire was used to collect data and SPSS version 23 was used for data analysis.

Results: The majority, 85(66.9%) of the healthcare workers were Community Health Extension Workers. There were 16(12.6%) midwives and 1(0.8%) medical doctors. In-service training on newborn care had been received by 69(54.3%) respondents, while 22(17.3%) respondents had received training on essential newborn care. Only twenty (33.3%) facilities discharge mother and newborn 24 hours after normal delivery. Postnatal services provided included early initiation of breastfeeding by 116(91.3%) respondents. Preventive services included chlorhexidine cord care given by 86(67.7%) respondents while 27(21.3%) and 26(20.5%) gave erythromycin/ tetracycline eye prophylaxis and vitamin k1 respectively.

Conclusion: Community Health Extension Workers were the major human resource for immediate newborn care; further research to determine their knowledge and skills are needed. The preventive neonatal services were few. More preventive care and 24-hour postnatal care are advocated as strategies to improve newborn outcomes.

El cultivo en invernadero permite obtener rendimientos mayores que los obtenidos a campo abierto, debido a un control mejor del ambiente. Bajo la hipótesis de que el color y las características del material de cubierta en invernadero de tipo túnel para producción de tomate afectan la transmisión de la radiación solar recibida por las plantas y por lo tanto crecimiento y rendimiento; el objetivo del estudio fue evaluar intensidad y distribución espectral de la radiación solar transmitida (Photosynthetic active radiation, PAR) a través de cuatro cubiertas de invernadero con características físicas y color diferentes, sobre contenido relativo de clorofila, tasa de fotosíntesis, crecimiento y rendimiento de un cultivo de tomate (Solanum lycopersicum L.). Para medir la intensidad de la radiación solar (400 a 700 nm) transmitida por cada cubierta se hizo la instalación de sensores quantum en el interior de invernaderos de tipo túnel; se determinó con un espectro radiómetro la característica espectral en la misma banda de radiación solar. El efecto de las cubiertas se analizó con un diseño completamente al azar con las repeticiones por tratamiento dentro de cada invernadero. Las plantas en los túneles con cubiertas de polietileno difuso de alta densidad de pigmentación roja y azul recibieron menos radiación solar en la banda de 400 a 700 nm de longitud de onda. Además, la radiación de 400 a 550 nm recibida por las plantas en el invernadero con cubierta de pigmentación roja fue mucho menor que la recibida por plantas bajo otras cubiertas. Las plantas en el invernadero con cubierta de polietileno azul recibieron menos radiación solar de la amplitud 600 a 700 nm. Esto no afectó el contenido de clorofila ni la tasa de asimilación de bióxido de carbono; sin embargo, hubo incremento significativo (p≤0.05) en altura de planta, pero con diámetro de tallo menor. Así como un rendimiento mayor, expresado en número de frutos por planta, peso y tamaño mayor de fruto en las plantas bajo túneles de polietileno con pigmentación roja y azul.

Published: October 2021

The larvae and pupae of Liometopum apiculatum, an ant species known as “escamolera” (Lap), are valued for their flavour and nutritional value. Currently demand at restaurants trade, high price and other factors have threatened their populations. However, in Mexico there is no risk assessment for this species. Therefore, information was compiled to evaluate the conservation status of L apiculatum. The species Risk Assessment Methodology (MER) of Appendix I in the Mexican Standard NOM-059-SEMARNAT-2010 determines the risk category of a species based on scores of four criteria and places a species as “Extinct in the wild, subject to special protection, threatened or in danger of extinction”. In this study, the related scores were, for Criterion A (taxon distributional area), 3 points (restricted distribution); Criterion B (habitat status regarding its natural development), 1 point (apt, or not limiting); Criterion C (biological vulnerability), 1 point (low vulnerability); and criterion D (impact of human activity on the taxon) scored 3 points (medium impact). The sum of the scores of the four MER criteria indicated that Lap (the escamolera ant) should be placed in the category of Subject to special protection (SSP). This information shall be used to design management and conservation policies for edible insects in Mexico.

Published: October 2021

En el complejo mundo de las relaciones interpersonales, el individuo se enfrenta a un proceso como la adolescencia que puede ser descrita como un periodo que transcurre entre los cambios biológicos, Psicos y psicológicos. Dado que es donde cambian los roles de niño a adolescente y donde se establece la identidad; estos procesos vienen de la mano del aprendizaje, apelando a un proceso de aprendizaje y flexibilidad cognitiva, en donde se aprecian diferentes teorías sobre este mismo fenómeno, en el cual el aprendizaje por imitación es determinante para la identificación con pares, teniendo en cuenta todos los procesos nombrados anteriormente, estos encuentran relación con "la personalidad proactiva que está vinculada a los intentos activos que realiza el individuo para efectuar cambios en su ambiente, solucionar problemas interpersonales, generar respuestas funcionales y considerar las consecuencias positivas" (Zampetakis, 2008, p. 155).

Why Youths Join the Terrorist Movements?
Authors:   Student/Researcher at Social Science and Psychology at Western Sydney, Mokhtar Ali Ibrahim
Published: October 2021

Abstract The salient role of terrorist movements is to recruit more members from different countries and cultures. Hence, it became palpable that terrorist movements, for instance, Al-Qaeda and ISIS have a clandestine method of recruitment that is obscure from the governments’ eyes. The incident of 11/9 had brought the attention of sociologists and politicians to examine the recruitment process of terrorist movements. Conclusively, several studies founded that terrorist movements utilise various techniques to recruit men, youths, children and women. The terrorist movements have been utilising the Islamic ideology as a fundamental ideology. They have been utilising social media as a pulpit for their propaganda. Still, the intricacy of terrorist movement recruitment is believed to be obscure. It is arduous for governments to cease the recruitment process of those movements, albeit the usage of modern technologies nowadays. Thus, sociologists and psychologists initiated investigating the socialisation process of terrorist movements and the brainwashing towards the newly recruited members. However, this paper examines sociologically and psychologically to answer the vital question: Why Youths Join the Terrorist Movements? By looking in-depth into some cases that stripped off their previous teachings, norms and behaviours to become new – fighters – for ISIS and Al-Qaeda. Therefore, this paper analyses the answer to the paper question from sociological and psychological perspectives.

Prosopis pallida (Humb. & Bonpl. ex Willd.) Kunth y Prosopis juliflora (Sw.) DC., son dos de las especies arbóreas de mayor importancia económica y ecológica en las zonas áridas y semiáridas del mundo. Las especies de Prosopis han llamado la atención por su gran capacidad para sobrevivir en ambientes muy inhóspitos. Este trabajo tuvo el objetivo de evaluar los efectos de la temperatura en la germinación de las especies mencionadas como un indicador de su respuesta al fuego. Se trabajó con 40 tratamientos resultantes del arreglo trifactorial 2x5x4+1, (dos especies, cinco valores de temperaturas, cuatro tiempos de exposición y un testigo), los cuales se asignaron a un diseño experimental completamente al azar con tres repeticiones. La normalidad de los datos se comprobó con la prueba de Shapiro-Wilks. La comparación de las medias se realizó con la prueba t de Student para la viabilidad y con un análisis de varianza y la prueba de Tukey para la diferencia entre pares de medias para el porcentaje de germinación. Se trabajó con un nivel de significancia del 0,05 (p=0,05). El análisis estadístico se realizó con el programa SPSS Statistics for Windows (Version 22.0). El porcentaje de germinación de las semillas utilizadas fue afectado tanto por el aumento de la temperatura como por el tiempo de exposición. No obstante, pudieran germinar después de la ocurrencia de fuegos de baja intensidad que generen temperaturas de hasta 80 y 100 oC para P. pallida y P. juliflora, respectivamente.

DNA and historical evidence indicate many colonial French Canadians were of Sephardic Jewish ancestry
Authors: Hirschman Elizabeth
Published: October 2021

The Spanish Inquisition in 1492 resulted in the deaths of thousands of Spanish Jews and the exile of around 150,000. The Huguenots and Acadians who settled in Colonial French Canada are assumed to be of Christian faith and ancestry. To support this hypothesis, the researcher uses a novel combination of methods drawn from historical records and artifacts, genealogies and DNA testing. In recent years, this combination of methods has led to the discovery that several of the Plymouth Colony settlers, Central Appalachian Colonial settlers, and Roanoke Colony settlers were of Sephardic Jewish origin. Thus, using the new methodology of ancestral DNA tracing, the researcher document that the majority of Huguenot and Acadian colonists in French Canada were of Sephardic Jewish ancestry.  They are most likely descended from Sephardic Jews who fled to France from the Iberian Peninsula in the late 1300s and early 1500s. The researcher additionally propose that some members of both groups continued to practice Judaism in the new world, thus becoming secret Jews or crypto-Jews. The researcher also finds evidence of Ashkenazi Jewish ancestry in both groups.

Reversal of residual muscle paralysis is usually done at the end of a General Anaesthesia with Relaxant Technique (GART) before extubation. However, some patients may have inadequate reversal of their residual muscle paralysis. This may lead to persistent muscle paralysis despite the patient being awake from anaesthesia. A scenario of “I can’t breathe” therefore comes to play which is scary and discomforting to the affected patients. We hereby present two cases of inadequate reversal of residual muscle paralysis in our patients who underwent different procedures under general anaesthesia. The aim of this presentation is to highlight the need for adequate reversal of residual muscle paralysis, the need to routinely monitor neuromuscular function during general anaesthesia and to review the existing literature.

A prática tradicional do congo, em especial a Banda de Congo Amores da Lua, do Mestre Ricardo Sales, apresenta alguns elementos que vão ao encontro da filosofia da arte de Walter Benjamin. A definição do campo do congo apresenta uma disputa de valores. A dialética benjaminiana é usada para a aproximação pelo lado dos mais despossuídos. O ato performático e os objetos usados no congo se aproximam da experiência ancestral. O calendário cíclico congueiro cria uma imagem anacrônica da contemporaneidade.
O Conceitualismo Lúdico de Bas Jan Ader: Performando a Identidade Transicional
Authors: Schoenberger Janna , Grando Angela , Araujo Léa
Published: October 2021

Seguindo as ideias de Huizinga em sua obra Homo Ludens (1938), proponho o termo Conceitualismo Lúdico para descrever a arte que floresceu em solo holandês dentre os anos de 1959 a 1975. Diferentemente da vertente mais austera do conceitualismo desenvolvido em Nova York e Reino Unido, o jogo era central para a vertente holandesa. Neste artigo discutirei como a consolidação de uma identidade, performada através de piadas de cunho satírico baseadas em estereótipos nacionais, se tornou a chave para a compreensão do processo artístico do artista conceitual holandês Bas Jan Ader. Embora grande parte do humor presente em seu trabalho seja óbvio, não houve nenhuma investigação séria sobre sua prática da ironia. Posicionarei Ader dentro da estrutura da arte conceitual humorística pós-guerra prevalecente na Holanda e Califórnia, localidades onde Ader viveu e estudou. Utilizando teorias do humor e da identidade demonstrarei como as piadas de Ader estão intrinsecamente ligadas a contextos sociais presentes nos dois lados do Atlântico, ambientes relevantes para o desenvolvimento artístico em todo curso de sua curta carreira. Uma investigação atenta sobre o trabalho de Ader revelará que a identidade densa desse artista, como vista em sua utilização do humor, é de fato, a característica central de seu trabalho.

Published: October 2021

Bu çalışmada 25 mm çaplı düz yüzeyli bir silindire saat yönü ve saatin tersi yönünde farklı dönme oranları (α=0.5, 1, 1.5, 2, 4) uygulandığında silindir etrafında oluşan akış yapısı deneysel olarak incelenmiştir. Öncelikle silindirin sabit olduğu durum için deneyler gerçekleştirilmiş, daha sonra da silindire farklı hızlarda ve yönlerde silindirin merkezinden dönme hareketi verilerek silindir etrafındaki akış yapısının değişimi incelenmiştir. Düşük dönme oranlarının (α) akış kontrolünde yetersiz olduğu, dönme oranının artması ile akış kontrol etkinliğinin arttığı görülmüştür. Sonuç olarak, düşük dönüş hızlarında silindirin dönme oranının olmadığı duruma benzer girdaplar oluşmaya başlamış ve Karman girdap caddesi dönme yönüne doğru sapmıştır. Fakat dönmenin etkisiyle oluşan girdapların küçülmesi Karman girdap caddesi boyutunu dönmeyen silindire göre daralmıştır. Yüksek dönme oranlarında sınır tabaka ayrılmasının ötelendiği, ölü akış bölgesinin silindire doğru daraldığı ve akış yönünde oluşan Karman girdap caddesinin oluşmadığı gözlenmiştir. Yüksek dönme oranları akış yönünde oluşan girdap kopmalarının tamamıyla ortadan kaybolmasına ve akışın dönme yönüne doğru bozulmadan ilerlemesine neden olmuştur.

Organización social y dominio masculino en las matemáticas
Authors: Espinosa Guia Claudia Gisela
Published: October 2021

Las investigaciones en el campo de Género y Matemáticas consideran el hallazgo de que las matemáticas son un dominio masculino, tema que este estudio toma como eje para describir su problema de investigación. El interés fue conocer al estudiantado que cursa Matemáticas en la Facultad de Ciencias de la UNAM, considerando su organización y las relaciones que construyen socialmente, a fin de mostrar cómo las matemáticas repercuten, o no, en la vida estudiantil en un espacio fuera del aula, pero dentro de la Facultad. Para su análisis se realizaron observaciones a profundidad a través del uso de una etnografía como herramienta principal para describir a detalle lo complejo que pueden ser las interacciones en las relaciones entre el estudiantado de matemáticas, en determinado tiempo, lugar, espacio o con quienes se relacione. Se encontró que Dominio Masculino en Matemáticas es, entre otras cosas, tener gusto y conocimientos en matemáticas, mostrar que saben matemáticas, discutir acerca de matemáticas y resolver problemas matemáticos entre pares. Estos aspectos fueron la clave para el estudiantado de matemáticas en las relaciones que establecen dentro de la facultad, en cambio, los estereotipos y las creencias no fueron temas relevantes entre ellas y ellos.

Hacia una reconceptualización de la imagen del estudiante indígena universitario
Authors: Lombardi González Karla Susana , Silas Casillas Juan Carlos
Published: October 2021

La concepción del estudiante indígena universitario se pone en cuestión cuando se sitúa en el campo de las percepciones académicas heredadas por el colonialismo. En este sentido, el siguiente texto tiene la intención de plantear una mirada abierta sobre la propia reconstrucción identitaria del joven indígena inserto en un ambiente de estudios académicos universitarios. Se toma como referencia teórica el concepto de capital identitario de James Côté. La metodología surge en el marco de la praxis reflexiva de dos investigaciones que se desarrollaron en el mismo espacio de acompañamiento académico y con los relatos de vida de los estudiantes de distintas comunidades. No se muestra como un reporte de investigación en sí mismo, sino que es un extracto analítico de ambos proyectos. Los resultados se describen a partir de la concepción que tuvieron de sí mismos, y de las acciones formativas que son producto de sus propias acciones y decisiones.

Estrategia de modulación para minimizar la potencia reactiva en el enlace de CA de convertidores CC-CC de tres puertos aislados
Authors: Troviano M. , Piris-Botalla L. E. , Oggier G.G.
Published: October 2021

El convertidor CC-CC de tres puertos aislados es de interés para los sistemas de almacenamiento de energía híbridos por su capacidad para controlar los flujos de energía de manera bidireccional, aumentar y disminuir la tensión y la operación con conmutación suave. El control convencional del flujo de energía se realiza aplicando un desfase entre las tensiones a bornes del transformador, lo que puede generar una elevada potencia reactiva debida a la corriente de circulación en el enlace de CA del convertidor, consiguiéndose rendimientos elevados sólo en un rango de operación limitado. Para aumentar el rendimiento en todo el rango de operación, este trabajo propone una estrategia de modulación que extiende la región de conmutación suave y minimiza la potencia reactiva. Esta estrategia aplica un ancho de pulso en el puerto de mayor tensión de CC, manteniendo la modulación tradicional de onda cuadrada en el puerto opuesto. Para validar la estrategia, se presentan resultados para diferentes escenarios de transferencia de potencia.
Mejora de la estabilidad dinámica de tensión en una microrred utilizando un DSTATCOM
Authors: Paredes L. , Molina M. , Serrano B.
Published: October 2021

En la actualidad, los sistemas eléctricos de potencia basados en microrredes están alcanzando un importante posicionamiento en diferentes localidades alrededor del mundo. Las múltiples tecnologías de generación distribuida empleadas en las microrredes modernas permiten una operación conjunta de fuentes de energías renovables y no renovables con múltiples tipos de cargas. No obstante, las cargas dinámicas de tipo motor de inducción (MI) representan uno de los factores más críticos que hacen que los sistemas de microrredes sean vulnerables a escenarios que podrían desencadenar en inestabilidades de tensión.  En este trabajo se propone la incorporación de dispositivos FACTS (sistemas de transmisión flexibles de ac) para mejorar la estabilidad dinámica de tensión en microrredes con alta penetración de cargas dinámicas. El trabajo se enfoca en el impacto de incluir un DSTATCOM (compensador síncrono estático de distribución) en una microrred con alta penetración de carga dinámica de tipo MI cuando ocurre una falla que provoca el aislamiento operativo de la microrred. Se analizan varios estudios de casos utilizando el sistema de prueba de microrred de la CIGRÉ. Los resultados muestran las mejoras en la estabilidad dinámica de tensión de la microrred con la operación coordinada de las tecnologías de generación distribuida y el DSTATCOM.

Published: October 2021

Introduction

Two experiments were designed to investigate the motivational role of the metacognitive self (MCS, meaning self-awareness of biases) and kind of feedback (success vs. failure vs. control group) in willingness to learn. We predict that the condition of failure enhances motivation to learn. Predictions relate to the first experiment and social incentives, not to spatial ones.

Material and methods

Three hundred ninety-eight participants were individually (in front of a computer with E-Prime) and randomly assigned to experiment 1 of a social task or experiment 2 of a spatial task. Each experiment included three groups: success, failure, and control. The independent variables were metacognitive self (MCS) and type of feedback (success vs. failure vs. control). The dependent variable was the willingness to learn. Logistic regression was applied to investigate the hypothesis that the higher the level of MCS is, the more likely it is that the participants will try to learn.

Results

As predicted, MCS was positively related to searching for self-diagnostic information in the first experiment. Furthermore, according to expectations, the experiment with a social task showed the main effects of both MCS and type of feedback. The spatial experiment did not reveal significant effects.

Conclusions

MCS is positively related to motivation to search for self-diagnostic information, and students are more willing to learn in the face of failure. According to expectations, the experiment with a social task substantiated the motivational role of MCS and the role of negative feedback in willingness to learn.
Coronavirus anxiety, fear of COVID-19,
hope and resilience in healthcare workers:
a moderated mediation model study
Authors: Yıldırım Murat , Güler Abdurrahim
Published: October 2021

Introduction

In the era of the global health crisis, mental health and well-being of people have been severely affected because of experiencing high levels of anxiety, stress, fear, and uncertainty related to COVID-19. This study investigated a moderated mediation model in which resilience mediated the link between coronavirus anxiety and fear of COVID-19, and this mediation effect was moderated by hope.

Material and methods

A cross-sectional study was conducted on 168 healthcare workers (Mage = 29.19 ± 6.13 years and 63.1% women) working at a state hospital in the eastern part of Turkey. They completed measures of coronavirus anxiety, fear of COVID-19, resilience, and hope during COVID-19 pandemic.

Results

The results indicated that resilience mediated the relationship between coronavirus anxiety and fear of COVID-19. Hope moderated the mediating path from coronavirus anxiety to resilience. Coronavirus anxiety had a stronger effect on resilience under the moderate and high levels of hope condition, compared to the low level of hope condition.

Conclusions

The findings suggest that resilience is an important mechanism explaining how coronavirus anxiety is associated with fear of COVID-19 and that this relation may depend on the levels of hope. Future prevention and intervention programs should focus on increasing hope and resilience when addressing mental health problems in the face of adversity.
Relationship dynamics:
the protective effect of relationship satisfaction
and dependency on parents’ mental health
after having a preterm baby
Authors: Okay İlknur , Yavuz Güler Çiğdem
Published: October 2021

Introduction

Having a premature infant who is hospitalized with the risk of death and potential health problems is a traumatic experience for many parents. The present study investigated the depression, anxiety, stress, and post-traumatic growth (PTG) experienced by couples after the premature birth of their babies in terms of their relationship dynamics.

Material and methods

The study was conducted on 209 individuals – 159 mothers (76.1%) and 50 fathers (23.9%) – who had premature babies born at or before 32 weeks of gestation. The participants completed the Relationship Assessment Scale, Emotional Dependency Scale, Post-Traumatic Growth Inventory, the Depression, Anxiety, and Stress Scale, and a sociodemographic form. For interpretation of the data, intervariable relationships were analyzed using the Pearson correlation coefficient, and the mediation models were analyzed by the regression-based bootstrapping technique using the PROCESS Macro.

Results

The relationship satisfaction and emotional dependency experienced by parents had a positive correlation with PTG following preterm birth. Relationship satisfaction was associated with lower levels of depression, anxiety, and stress. Emotional dependency was correlated with lower levels of depression and stress but not anxiety. For the mediating variables, it was found that depression and anxiety had a full mediating role between relationship satisfaction and PTG but stress did not. It was determined that depression had a partial mediating role between emotional dependency and PTG but anxiety and stress did not.

Conclusions

The study findings revealed the importance of establishing family- and baby-centered neurodevelopmental neonatal intensive care units (NICUs). The results suggested that having healthcare professionals, primarily nurses and doctors, make observations about the relationship dynamics of parents during their stay at the NICU and guide parents to receive psychological support if they perceive weaknesses in the relationship – since such weaknesses predict possible risks of depression, anxiety and stress – would support the functionality of families. The findings are discussed, and future directions are suggested.

Introdução: O feijão-caupi, Vigna unguiculata, possui um extraordinário papel na alimentação da população das Regiões Norte e Nordeste do país. Porém essa cultura ainda é prejudica pela perda significativa da produção devido ao ataque de insetos-pragas e má qualidade do produto devido ao uso de defensivos químicos sintéticos. No presente trabalho o efeito do óleo do catolé Syagrus cearensis Noblick como defensivo natural, foi estudado sobre o caruncho Callosobruchus maculatus em feijão-caupi ambos adquiridos na cidade de São José do Belmonte, sertão de Pernambuco. Objetivo: Extração do óleo fixo da amêndoa dos frutos da S. cearensis e verificar a sua atividade inseticida contra C. maculatus, besouro que mais atinge o feijão-caupi armazenado. Material e métodos: Para o experimento utilizou-se recipientes plásticos transparentes, seringa e balança doméstica, todos de baixo custo e acessível comercialmente. Os frutos foram coletados em campo em fase inicial de maturação sendo os endocarpos quebrados manualmente resultando em peso total de 576, 048g e em seguida triturado em liquidificador. O óleo foi extraído utilizando à técnica de refluxo com amostra de 40,062g da qual foi adicionada a 250 ml de água destilada sendo colocado em mata aquecedora com temperatura variando de 80° C a 97° C com duração de 2 h. Para os testes biológico foi criada colônia do C. maculatus em laboratório. Os grãos foram adquiridos no município de São José do Belmonte, PE. Os testes de atividade foram conduzidos em 20 potes de plástico de 250 com 20g de feijão-caupi infestados com 10 insetos com 0-72 horas de emergência. Os tratamentos foram 0,0mg (testemunha); 17,6mg; 52,8mg; 88mg; e 123,2mg do óleo para cada 20g do feijão-caupi. Após 48h foi avaliado a mortalidade. Resultados: As doses de 0,0 mg a 123,2 mg do óleo por 20g de feijão foram analisadas e como resultado estimou-se a Concentração Letal (CL50) = 64,96 por meio da opção “linha de tendência” do programa Excel 2010, Office, Microsoft. Conclusão: Os bons resultados aqui apresentados revelaram que o óleo do catolé é um bioinseticida economicamente viável e acessível para o manejo do caruncho em grãos de feijão-caupi armazenados.
