Supplying Basic Education and Learning to Sub-Saharan Africa in the Twenty-First Century
Authors: Biao Idowu
Published: April 2018

This article posits that schooling in Sub-Saharan Africa has so far failed to yield the results expected of it on twogrounds. First, the population of persons accessing both basic education and other levels of education is negligible incomparison with those who ought to access them (1 out of every 4 primary school age children; less than half of thequalified secondary school students; about 7% gross enrolment within higher education). Second, schooling hasfailed to deliver the kind of socio-economic development expected in the case of Sub-Saharan Africa as a highprevalence of poverty still exists and incongruity continues to exist between the education provided and thelivelihoods of Sub-Saharan Africans. Using this poor educational and development performance as justification, amore utilitarian, relevant and sustainable approach to basic education and learning is recommended for Africa goingforward. This recommended approach combines both the current school system with a special non-formal educationsystem for the purpose of delivering basic education and learning in Sub-Saharan Africa in the twenty-first century.

Positive Yield Impact of Predacious Mites in Tea Production Areas of Kenya
Authors: Mutisya Daniel , Banhawy E. , Cheramgoi Evelyn
Published: April 2018

Tea agro ecosystems are least disturbed in comparison to other crop systems due to the plant canopy type. A survey on predacious mites’ abundance and impact on leaf yield in different tea production areas was carried out in 2014-2015 in Kenya. Major pest species were the red spider mite Oligonychus coffeae and the yellow thrip, Scirtothrips dorsalis. The red crevice mite, Brevipalpus phoenicis was found in few areas and in low numbers. Predacious mites of Phytoseiidae Family were highest at 5.8 and 6.8 mites per sample during dry and wet seasons, respectively. Phytoseiid abundance during the dry and wet seasons did not differ much within most sample sites. Presence of phytoseiid mites in combination with NPK-fertilizer-high altitude led to the strongest correlation to leaf yield than any other combination variable. High phytoseiid density- high altitude was third with positive impact to yield increase after high altitude combined with NPK-fertilizer. The findings here show contributory positive impact of phytoseiids in tea leaf yield in an agro eco-system.

Context.—

Graft-versus-host disease of the gastrointestinal tract is a common complication of hematopoietic stem cell transplant associated with significant morbidity and mortality. Accurate diagnosis can be difficult and is a truly clinicopathologic endeavor.

Objectives.—

To assess the diagnostic sensitivity of gastrointestinal graft-versus-host disease using the 2015 National Institutes of Health (NIH) histology consensus guidelines and to analyze histologic findings that support the guidelines.

Design.—

Patients with allogeneic hematopoietic stem cell transplants were identified via a retrospective search of our electronic medical records from January 1, 2005, to January 1, 2011. Endoscopies with available histology were reviewed by 2 pathologists using the 2015 NIH guidelines. The clinical diagnosis was used as the gold standard. A nontransplant set of endoscopic biopsies was used as a control.

Results.—

Of the 250 total endoscopies, 217 (87%) had a clinical diagnosis of gastrointestinal graft-versus-host disease. Use of the NIH consensus guidelines showed a sensitivity of 86% and a specificity of 65%. Thirty-seven of 58 (64%) cases with an initial false-negative histopathologic diagnosis were diagnosed as graft-versus-host disease on our review.

Conclusions.—

Use of the NIH histology consensus guidelines results in a high sensitivity and specificity, thereby decreasing false-negatives. Additionally, use of the NIH guidelines aids in creating uniformity and diagnostic clarity. Correlation with clinical and laboratory findings is critical in evaluating the differential diagnosis and to avoid false-positives. As expected, increased apoptosis with decreased inflammation was associated with a pathologic diagnosis of graft-versus-host disease and supports the NIH guidelines.

Using History to Model with Mathematics: The German Tank Problem
Authors: Roy George J. , Eli Jennifer A. , Leslie Hendrix , Graul LuAnn
Published: April 2018

During World War II, the Allied Forces were concerned with the monthly production of tires, tanks, and other military equipment in Germany (Flaspohler and Dinkheller 1999; Ruggles and Brodie 1947). Knowing these production totals was important for international security. To determine military production, the Allied Forces in England recruited individuals from a wide range of educational and occupational backgrounds to help analyze serial numbers found on military equipment and to analyze secret codes (Pioneer Productions 2014). We used this historical context to challenge a class of twenty-six seventh-grade students to imagine themselves as one of these codebreaking analysts while studying random samples and learning to draw inferences about a population (CCSSI 2010).

Performing arts: Benefits and potentials within special education and ASCs
Authors: Roncaglia Irina
Published: April 2018

This editorial paper aims to present and explore the role of Performing Arts within Special Education and individuals with Autism Spectrum Conditions (ASC). It provides some initial introduction of recognized benefits and evidence based studies within health and wellbeing, education and society. It then aims to focus on how through engagement and development in the performing arts, three fundamental psychological needs can be developed, nurtured and maintained: 1) autonomy, 2) belonging and 3) competence. It aims to explain how by adopting a methodology through a process of ‘performance’ the aforementioned psychological needs can be addressed within special education and individuals with additional needs and with autistic individuals (ASC). Through a creative and yet structured approach a number of skills can be taught with significant benefits and positive short and long-term outcomes. This creative process also aims to highlight how specific barriers in accessing their learning can be overcome. It concludes by providing some suggestions for further evidence-based research in this field so as to strengthen and further develop the already but somehow limited existing evidence based of the benefits of Performing Arts.

Primer Design Using Polymerase Chain Reaction for SNPs Analysis in SLC22A1 rs622342 Encoding OCT1 as Metformin Main Transporter
Authors: Rochmy Istikharah  , Vitarani Dwi Ananda Ningrum  , Baiq Maylinda Gemantari
Published: April 2018

Organic Cation Transporter 1 (OCT1) is the primary transporter of metformin mainly located in hepatocytes, which plays an important role in metformin action to inhibit gluconeogenesis so as to reduce blood glucose. Genetic polymorphism of SLC22A1 that encodes OCT1, one of which is rs622342, has been widely reported and proven to decrease the antidiabetic effect of metformin. This study aimed to design primers and to obtain an optimum condition for polymerase chain reaction (PCR) process that can detect the genetic polymorphism of SLC22A1 rs622342. Primers were computationally designed in primer 3 webpage and analyzed with Primer BLAST and Oligo Analyzer. Optimization of PCR condition was conducted for temperatures of denaturation, annealing, and elongation as well as for the number of cycles in PCR process. Sensitivity test was performed on PCR condition using a variety of volumes and DNA template qualities undergoing multiple freeze-thaw cycles. The obtained pair, forward primer (5’- CAG AGA GAA TCA GTG AGC TGT G-3’) and reverse primer (5’- CCC AGG CTG GTC TTT TTA AG-3’), was proven to be capable of amplifying DNA sequence containing SNPs in rs622342 at 96°C denaturation, 60°C annealing, and 72°C elongation temperatures with a 30-cycle iteration. Such PCR condition could amplify DNA with 0.2 µL of template volume and 7 freeze-thaw cycles. Therefore, in addition to the selected primer pairs and PCR condition to analyze SNPs in rs622342, this study also recommends that the volume of DNA template having undergone multiple freeze-thawing be increased if the amplicon PCR products are unqualified.

Authors: Conesa Ros E.
Published: April 2018

Actualmente, la población adulta general utiliza multitud de modalidades deportivas, actividades dirigidas y medios de locomoción para realizar la actividad física diaria recomendada por los organismos e instituciones de referencia. Entre estas nuevas disciplinas ha surgido con fuerza en los últimos años diferentes modificaciones de actividades de baile de salón y bailes modernos. Para conocer si estas disciplinas exigen del participante la intensidad de esfuerzo recomendada por la literatura científica internacional, este trabajo analizó la intensidad relativa expresada como porcentaje de la frecuencia cardiaca máxima (%FCmax) y de reserva (%FCR) en los estilos de baile de Hip-Hop y Salsa con sesiones programadas y dirigidas por expertos.Siete jóvenes con experiencia en la práctica de actividades dirigidas con soporte musical realizaron 5 sesiones estandarizadas e iguales en volumen, intensidad y pasos para cada una de las dos modalidades sometidas a estudio. Los resultados muestran que el baile Hip-Hop tiene una exigencia de intensidad media y máxima que le permite catalogar como actividad vigorosa (%FCR 64% y 86%), mientras que la Salsa debe catalogarse como intensidad moderada (%FCR 57% y 77%). Aunque ambas modalidades cumplen los requisitos de intensidad recomendadapara la población adulta sana, la mayor intensidad relativa que presenta el Hip-Hop permite reducir el volumen semanal total a unos 75 min para alcanzar los objetivos cardiosaludables marcados, mientras que la Salsa requiere de al menos 150 minutos semanales.

El objetivo fue evaluar las estrategias de ritmo y las respuestas metabólicas y fisiológicas  de remeros novatos y experimentados, en distancia de 2000m. La muestra estuvo compuesta por 7 remeros universitarios y de clubes, 5 de los cuales eran novatos (edad 22.4±2.6 años, altura 182.6±8.4 cm, peso 79.7±8.9 kg), y 2 experimentados (edad 23.0±4.2 años, altura 194.1±4.1 cm, peso 90.3±2.0 kg). Todos los participantes realizaron una prueba de 2000m en un ergómetro de remo, seguidos por 3 pruebas en orden aleatorio (500m, 1000m, 1500m) a la velocidad y tiempo de carrera establecidos según la primera prueba de 2000m. La última sesión fue un test de 2max. Durante estas pruebas se realizó análisis de gases, hematología, frecuencia cardiaca, tiempos parciales, velocidad de carrera y distancias. La acumulación de lactato en sangre (BLa) en los remeros novatos se incrementó progresivamente y se estabilizó en los últimos 500m. Los remeros experimentados aumentaron gradualmente la acumulación de lactato, pero lo mantuvieron en el tercer cuarto (1000-1500m), lo que les permitió mayor acumulación en el cuarto final (1500-2000m). El volumen de consumo de oxígeno ( 2) aumentó linealmente hasta los 500m finales en los remeros experimentados, mientras que en los remeros novatos fluctuó durante toda la prueba. Respecto al ritmo, los remeros novatos siguieron la estrategia “all-out” esperada, mientras que, inesperadamente, los remeros experimentados disminuyeron la velocidad progresivamente hasta el punto medio (1000m), en el que mantuvieron una velocidad de 5.10m.s-1. Estos resultados sugieren que a un determinado nivel fisiológico y metabólico, los remeros experimentados están más adaptados a las demandas de una regata de remo de 2000m. Sin embargo, parece que no siempre siguen una estrategia  “J-Shaped”.

Genetic bottleneck and founder effect signatures in a captive population of common bottlenose dolphins Tursiops truncatus (Montagu 1821) in Mexico
Authors: Améndola-Pimenta Monica , Camelo-Marrufo Miriam , Zamora-Briseño Jesús Alejandro , Hernández-Velázquez Ioreni Margarita , Zamora-Bustillos Roberto , Rodriguez Canul Rossanna
Published: April 2018

Background. The captive cetacean industry is very profitable and popular worldwide, focusing mainly on leisure activities such as “Swim-with-dolphins” (SWD) programs. However, there is a concern for how captivity could affect the bottlenose dolphin Tursiops truncatus, which in nature is a highly social and widespread species. To date, there is little information regarding to the impact of restricted population size on their genetic structure and variability.

Methods. The aim of this study was to estimate the genetic diversity of a confined population of T. truncatus, composed of wild-born (n=25) from Cuba, Quintana Roo and Tabasco, and captive-born (n=24) dolphins in southern Mexico, using the hypervariable portion of the mitochondrial DNA and ten nuclear microsatellite markers: TexVet3, TexVet5, TexVet7, D18, D22, Ttr19, Tur4_80, Tur4_105, Tur4_141 and GATA098.

Results. Exclusive mtDNA haplotypes were found in at least one individual from each wild-born origin populations and in one captive-born individual; total mean haplotype and nucleotide diversities were 0.912 (±0.016) and 0.025 (±0.013) respectively. At microsatellite loci, low levels of genetic diversity were found with a mean number of alleles per locus of 4 (±2.36), and an average expected heterozygosity over all loci of 0.544 (±0.163). Measures of allelic richness and effective number of alleles were similar between captive-born and wild-born dolphins. No significant genetic structure was found with microsatellite markers, whereas the mtDNA data revealed a significant differentiation between wild-born organisms from Cuba and Quintana ROO.

Discussion. Data analysis suggests the occurrence of a recent genetic bottleneck in the confined population probably because of a strong founder effect, given that only a small number of dolphins with a limited fraction of the total species genetic variation were selected at random to start this captive population. The results herein provide the first genetic baseline information on a captive bottlenose dolphin population in Mexico.

Published: April 2018

Os postos de revenda de combustíveis são classificados como atividades potencialmente ou parcialmente poluidoras que geram impactos significativos ao meio ambiente. Portanto, o conhecimento da localização, da situação e do entorno dos postos torna-se necessário para minimizar os impactos ambientais. Este artigo visa analisar o entorno dos Postos de Combustíveis da cidade de Crato, no Ceará. Para realização desta pesquisa, foram desenvolvidas atividades de levantamento bibliográfico e das legislações referentes ao tema, georreferenciamento dos postos e sua análise. Dos 24 postos instalados na Cidade, constatou-se que: 6 postos estão a menos de 50m de distância um do outro; apenas 2 encontram-se a menos de 30m de um corpo hídrico; e 5 postos localizam-se a menos de 100m de poços de captação de água. A proximidade desses postos representa perigos para o ambiente, incluindo a segurança da sociedade. O atendimento às distâncias mínimas estabelecidas pelas legislações contribuiria para minimizar os efeitos negativos que os postos podem causar.

Published: April 2018

O fruto de jatobá usado como alimento apresenta propriedades que auxiliam na prevenção de doenças crônicas. O estudo da influência das condições climáticas na decomposição térmica do fruto foi proposto para avaliar, com base em suas características químicas, sua possível aplicação no setor farmacêutico. Neste trabalho, serão analisados frutos das safras de 2010 e 2012. O fruto de jatobá se mostrou uma matriz complexa para a caracterização química, físico-química e termoanalítica. As curvas termogravimétricas evidenciaram que a decomposição térmica de todas as amostras é completa a 900ºC. Observou-se que as amostras de casca lavada de 2012 (CASL12), casca não lavada de 2012 (CASNL12) e semente de 2012 (SEM12) perderam algumas bandas em relação a 2010, indicando que as condições climáticas afetaram os frutos. Com relação a todas as amostras estudadas, a fibra de 2012 (FIB12) e a SEM12 apresentaram maiores teores de cinza e umidade, respectivamente. Porém, as amostras de polpa da safra de 2012 e fibra apresentaram quatro eventos de decomposição térmica, diferindo da safra de 2010. As condições climáticas das safras precedentes se mostraram muito diferentes e isso afetou consideravelmente o comportamento térmico dos frutos de jatobá.

This article is a study about the relation among the mediation with dance, ‘site specific’ process and performance as indirect products from the mediation experience. Part of the Masters’ project “Do not touch. Dance, though. Dance and mediation in the Contemporary Museum”, the project put a heterogeneous group into living mediations that combine dance improvisations as a way to talk about contemporary art.

Keywords: Dance. Performance. Site specific. Mediation.

Pensando na arte da Diáspora
[Adalberto Santos]
Authors: Santos Adalberto
Published: April 2018

O texto que agora apresentamos é resultado de vaguear por pensamentos sobre nós mesmos.
Por meio dele, damos vazão ao anseio em sermos produto e produtores de nossas histórias.
Nesse caminho, são diversos os saberes que nos orientam, de um lado a forte, mas não somente,
influência que os estudos decoloniais têm sobre nós. De outro lado, uma percepção de mundo
construída em fios tênues, mas resistentes, que nos informa dos dilemas, sonhos e possibilidades
os quais acometem nossos corpos negros. Seu formato ensaístico nos dá liberdade para divagar
por variados percursos sem, contudo, abdicar da sensível reflexão sobre o caminho que nos
conduziram até aqui.
Artes cênicas negras no Brasil: Das memórias aos desafios na formação acadêmica
[Amélia Vitória de Souza Conrado]
Authors: Conrado Amélia Vitória de Souza
Published: April 2018

O texto faz uma abordagem crítica sobre as artes cênicas no Brasil, por meio de questionamentos
e reflexões acerca do paradigma científico branco-europeu nesse campo de conhecimento.
Ao tratar de aspectos que se referem à história e produção do teatro e da dança negra, assim
como os artistas, grupos, espetáculos, repertórios e dramaturgias, a proposta deste artigo
surge para afirmar a ação dos artistas negros enquanto movimento de negritude, que envolve
desde as formas existentes das manifestações artístico e culturais negras nas suas expressões
comunitárias presentes em diversas localidades, até as formas dramatúrgicas que se expressam
nos palcos, como espetáculos. Enxergando o espaço acadêmico como ambiente estratégico para a
proposição de estudos de poéticas em diferentes formas de expressão e conceitos, consideramos
imprescindível a ação mobilizadora da comunidade negra acadêmica em luta pelos direitos sociais,
nos quais o pensamento crítico das artes negras revela uma epistemologia e metodologia capaz
de contemplar e compreender a trama de diálogos impregnados por tensões sociais, políticas, existenciais e históricas, nas quais as artes detêm uma qualidade questionadora.

A teatralidade de si-mesmo no ensino do teatro
[Juliano Casimiro de Camargo Sampaio]
Authors: Sampaio Juliano Casimiro de Camargo
Published: April 2018

Este artigo apresenta uma revisão bibliográfica de parte dos textos escritos em língua portuguesa
sobre as noções de teatralidade. Tal iniciativa se dá pela necessidade de se compreender como
professores de teatro acessam a temática no Brasil. Ainda, propomos pensar desdobramentos das
noções de teatralidade para a educação básica brasileira a partir do que chamamos de teatralidade
de si-mesmo. Resulta dessa iniciativa um deslocamento de relações do tipo eu-objeto-outro,
como nas teatralidades de cunho mais espetacular, para relações de natureza eu-objeto-eu, em
princípios da teatralidade de si-mesmo, no contexto do ensino de teatro.

Published: April 2018

Objective

Optimal targeted treatment in rheumatoid arthritis requires early identification of failure to respond. This post hoc analysis explored the relationship between early disease activity changes and the achievement of low disease activity (LDA) and remission targets with tofacitinib.

Methods

Data were from 2 randomized, double‐blind, phase III studies. In the ORAL Start trial, methotrexate (MTX)–naive patients received tofacitinib 5 or 10 mg twice daily, or MTX, for 24 months. In the placebo‐controlled ORAL Standard trial, MTX inadequate responder patients received tofacitinib 5 or 10 mg twice daily or adalimumab 40 mg every 2 weeks, with MTX, for 12 months. Probabilities of achieving LDA (using a Clinical Disease Activity Index [CDAI] score ≤10 or the 4‐component Disease Activity Score in 28 joints using the erythrocyte sedimentation rate [DAS28‐ESR] ≤3.2) at months 6 and 12 were calculated, given failure to achieve threshold improvement from baseline (change in CDAI ≥6 or DAS28‐ESR ≥1.2) at month 1 or 3.

Results

In ORAL Start, 7.2% and 5.4% of patients receiving tofacitinib 5 and 10 mg twice daily, respectively, failed to show improvement in the CDAI ≥6 at month 3; of those who failed, 3.8% and 28.6%, respectively, achieved month 6 CDAI‐defined LDA. In ORAL Standard, 18.8% and 17.5% of patients receiving tofacitinib 5 and 10 mg twice daily, respectively, failed to improve CDAI ≥6 at month 3; of those who failed, 0% and 2.9%, respectively, achieved month 6 CDAI‐defined LDA. Findings were similar when considering improvements at month 1 or DAS28‐ESR thresholds.

Conclusion

In patients with an inadequate response to MTX, lack of response to tofacitinib after 1 or 3 months predicted a low probability of achieving LDA at month 6. Lack of an early response may be considered when deciding whether to continue treatment with tofacitinib.

Authors: Lange Elvira , Kucharski Daniel , Svedlund Sara , Svensson Karin , Bertholds Gunhild , Gjertsson Inger , Mannerkorpi Kaisa
Published: April 2018

Objective

To evaluate the effect of a moderate‐to‐high–intensity, aerobic and resistance exercise with person‐centered guidance in older adults with rheumatoid arthritis (RA), through a randomized controlled multicenter trial.

Methods

Older adults (ages 65–75 years) with RA (n = 74) were randomized to either a 20‐week exercise intervention at a gym (n = 36) or to home‐based exercise of light intensity (n = 38). Assessments were performed at baseline, at 20 weeks, and at 12 months. The primary outcome was the difference in the Health Assessment Questionnaire disability index (HAQ DI) score, and the secondary outcomes were the differences in physical fitness assessed by a cardiopulmonary exercise test, an endurance test, the timed up and go test, the sit to stand test, and an isometric elbow flexion force measurement.

Results

No significant differences between the groups were found for the primary outcome, HAQ DI score. Within the intervention group there was a significant improvement in the HAQ DI score when compared to baseline (P = 0.022). Aerobic capacity (P < 0.001) and 3 of 4 additional performance‐based tests of endurance and strength significantly improved (P < 0.05) in the intervention group when compared to the control group. In the intervention group, 71% of patients rated their health as much or very much improved compared to 24% of patients in the control group (P < 0.001). At the 12‐month follow‐up, there were no significant differences in change between the 2 groups on the HAQ DI score. A significant between‐group difference was found for change in an endurance test (P = 0.022).

Conclusion

Aerobic and resistance exercise with person‐centered guidance improved physical fitness in terms of aerobic capacity, endurance, and strength in older adults with RA.

Published: April 2018

Metal foams may have applications in the field of catalytic supports, but the available manufacturing processes are too expensive for industrial use. The goal of the paper is to investigate and compare alternative cost‐efficient manufacturing methods, aimed at producing open‐cell aluminum foams for low‐temperature catalytic applications. The explored process chains are 1) solid state bonding of stacked thin slices of closed cell foams; 2) the conventional method of sintering and dissolution of aluminum powders with space holder; 3) sintering and dissolution of recycled aluminum turning chips with space holder. The process chains and their main parameters are described in detail. The morphological properties of the produced open‐cell foam samples, relevant to catalytic applications (cell size, hydraulic porosity, total porosity, surface to volume ratio), are measured and compared. Finally, their heat transfer properties are experimentally compared. The foams produced by the sintering and dissolution process exhibit the most favorable compromise among the goals of reducing the manufacturing cost, increasing the heat transfer coefficients, controlling the cell morphology.
Poly(P‐Phenylene Terephthalamide) Fibers Reinforced with Ultrathin Ceramic Coatings

Published: April 2018

The poly(p‐phenylene terephthalamide) (PPTA) fibers are engineering polymer materials with high strength and stiffness, lightweight, and outstanding fatigue characteristics. However, these materials exhibit drawbacks, namely, anisotropic mechanical strength along the tensile and compressive directions. In particular, they show low compressive strength, and mismatched thermal expansion as well as moisture uptake and oxidative stability along the axial and radial directions. Here, the authors describe a hybrid material approach by integrating ultrathin ceramic coatings (alumina or silica) onto PPTA fibers to enhance their compressive modulus by 2.5 times. In addition, these ceramic coating improve the energy absorption, thermal conductivity, and chemical stability of PPTA fibers, while their flexibility and lightweight are preserved. This strategy provides a new route for the preparation of high performance polymer fibers for advanced engineering applications.
Enhancement of Lightweight Composite Parts with Robust Cellular Structures by Combining Fused Deposition Modeling and Electromagnetic Induction Heating
Authors: Wang Jianlei , Senthil T. , Wu Lixin , Zhang Xu
Published: April 2018

A novel approach combining fused deposition modeling and electromagnetic induction heating is developed to fabricate lightweight cellular composite parts, where the composite filaments are prepared by adding the Babbitt alloy powders (LSn‐03) and the foaming agents (PTSS) into ABS matrix. The electromagnetic induction furnace is employed to heat the fabricated parts to form porous structures with rougher surfaces and improve the interfacial behaviors by making the interfaces getting blurred. Three types of pores are observed, including physical gaps, defects, and spherical holes. It is found that the heating time plays an important role in pore sizes and has little influence on porosity. The effects of content of LSn‐03 and PTSS on pore sizes and porosity are also investigated to gain insight into the cellular structures. The testing results show that the heating treatment exerts a positive influence on the mechanical properties at a relatively high filling density. Polycarbonates are adopted as shells to further improve the mechanical properties of the fabricated parts, revealing that the tensile and compressive strength increase by 20% and 25%, respectively. The instance of the honeycomb parts further demonstrates the advantages of the approach to fabricate the lightweight cellular composite parts with excellent performance.
