Maximizing Telerehabilitation for Patients With Visual Loss After Stroke: Interview and Focus Group Study With Stroke Survivors, Carers, and Occupational Therapists
Authors: Dunne Stephen , Close Helen , Richards Nicola , Ellison Amanda , Lane Alison R 
Published: July 2020

Background
Visual field defects are a common consequence of stroke, and compensatory eye movement strategies have been identified as the most promising rehabilitation option. There has been a move toward compensatory telerehabilitation options, such as the Durham Reading and Exploration (DREX) training app, which significantly improves visual exploration, reading, and self-reported quality of life.

Objective
This study details an iterative process of liaising with stroke survivors, carers, and health care professionals to identify barriers and facilitators to using rehabilitation tools, as well as elements of good practice in telerehabilitation, with a focus on how the DREX package can be maximized.

Methods
Survey data from 75 stroke survivors informed 12 semistructured engagement activities (7 focus groups and 5 interviews) with 32 stroke survivors, 10 carers, and 24 occupational therapists.

Results
Thematic analysis identified key themes within the data. Themes identified problems associated with poststroke health care from both patients’ and occupational therapists’ perspectives that need to be addressed to improve uptake of this rehabilitation tool and telerehabilitation options generally. This included identifying additional materials or assistance that were required to boost the impact of training packages. The acute rehabilitation setting was an identified barrier, and perceptions of technology were considered a barrier by some but a facilitator by others. In addition, 4 key features of telerehabilitation were identified: additional materials, the importance of goal setting, repetition, and feedback.

Conclusions
The data were used to try to overcome some barriers to the DREX training and are further discussed as considerations for telerehabilitation in general moving forward.

Published: July 2020

This study aims to explore the consumptive behaviour of people in a modern shopping centre, namely the Mall. Today the Mall is not just a shopping centre or just a place of prestige for some people. Mall at this time has formed a behaviour that reinforces individualism and consumer behaviour without realizing it. This reality is a consequence of an urban society that influenced by capitalist forces in shaping people's behaviour for profit. In this article, the author uses a literature study approach with primary data sources in the form of theoretical literacy related to consumer behaviour and secondary data from electronic media about Mall development. The pattern of consumptive behaviour in the Mall shopping centre which has been considered reasonable keeps the community in the grip of the capitalist. Make society more individualistic and consumptive behaviour.
Studi ini bertujuan mengkaji tentang perilaku konsumtif masyarakat di tempat pembelanjaan modern yaitu Mall. Saat ini Mall tidak hanya menjadi pusat berbelanja semata, ataupun hanya sebagai tempat prestise bagi sebagian masyarakat. Mall pada masa sekarang ini telah membentuk suatu perilaku yang mempertegas individualisme dan perilaku konsumtif tanpa sadar. Realitas ini adalah konsekuensi dari masyarakat urban yang dipengaruhi kekuatan kapitalis dalam membentuk perilaku masyarakat demi meraih keuntungan. Dalam artikel ini penulis menggunakan pendekatan studi literatur dengan sumber data primer berupa literasi teoritis berkaitan dengan perilaku konsumtif dan data sekunder dari media elektronik tentang perkembangan Mall. Pola perilaku konsumtif di pusat perbelanjaan Mall yang telah di anggap wajar, justru membuat masyarakat terus berada dalam cengkeraman kapitalis. Membuat masyarakat semakin individualis dan berperilaku konsumtif.
A TRANSFORMAÇÃO DE MARIA: UM ESTUDO SOBRE REPRESENTAÇÕES DO FEMININO E CONSTRUÇÕES IDENTITÁRIAS NA PRÁTICA DE DANÇAS CIGANAS
Authors: Marques Cíntia Bueno 
Published: July 2020

A dança é uma forma de expressão rica em significados. Na cultura cigana, a música e a dança estão presentes, tanto como forma de expressão dos sentimentos, quanto como ritual de conexão com a natureza e com a espiritualidade. Homens e mulheres têm diferentes papéis representados nessa dança que refletem modos de ser, crenças e valores próprios. Tais representações são expostas, não somente pelo repertório de movimentos executados, mas pelo conjunto de elementos que compõem a cena da dança. Esse texto resulta da pesquisa desenvolvida como trabalho de conclusão do Curso de Especialização em Dança que teve como objetivo analisar representações do feminino, presentes nas danças ciganas e de que modo essas representações podem refletir transformações naqueles que a praticam. A partir da abordagem qualitativa, a pesquisa adotou o método descritivo, empregando como técnica o estudo de caso. Nesse sentido, não pretendeu produzir generalizações a partir do estudo, porém, foi possível a partir dos resultados apresentados, reconhecer o potencial da dança como tecnologia de si, para promover reflexões e desencadear transformações positivas. Palavras-chavesDanças Ciganas. Identidades. Representações.

Published: July 2020

O artigo tem como objetivo principal problematizar as representações infantis, vinculadas ao que nomeamos de infância verde, postas em circulação a partir de publicações do site Catraquinha que é endereçado a pais, mães, responsáveis e educadoras/es. Para empreender as análises foram selecionadas 91 matérias publicadas entre junho e dezembro de 2016, cujos títulos continham as palavras infância(s) e ou criança(s). A partir do campo teórico dos Estudos Culturais em Educação, de viés pós-estruturalista, as análises centraram-se na discussão a respeito do forte apelo em estabelecer relação entre crianças e natureza, com o intuito de produzir sujeitos consumidores de uma ideia “verde”: como o uso de tecnologias sustentáveis, produtos orgânicos e uma vida saudável.
A Geografia da Televisão e suas Trocas Simbólicas
Authors: Gonçalves Julio Cesar , Rovida Mara 
Published: July 2020

Diante da constatação de que no espectro eletromagnético a distribuição dos sinais para transmissões de rádio e TV não acompanha outras formas oficialmente utilizadas nas divisões administrativa, política e territorial do espaço no país, esta pesquisa, ainda em fase inicial, tem como objetivo compreender como se dão as trocas simbólicas entre Sorocaba e Jundiaí, cidades médias que nunca tiveram laços entre si, mas foram unidas pela geografia da televisão. Utilizando-se de metodologia empírico-teórica, tomando como referência a teoria social da mídia de John Thompson e a ressignificação dos espaços geográficos de Milton Santos, o estudo busca identificar qual visibilidade o local ganha na programação da maior rede de televisão do Brasil e como isso repercute nas relações entre sorocabanos e jundiaienses. Os resultados a serem alcançados podem permitir entender as novas relações entre as duas cidades cerca de duas décadas depois de elas terem se ligado pela televisão
Análisis de variables productivas y socio-empresariales de productores de aguacate hass de dos municipios del Cauca para la creación de indicadores para la toma de decisiones del sector rural
Authors: Lopez Castaño Héctor Fabio , Braga Jessica Almeida , Brandão de Oliveira Max 
Published: July 2020

Contextualización: En el artículo se aborda la aplicación de técnicas de análisis de datos multivariados en el sector agro, con el propósito de caracterizar a dos grupos de agricultores de aguacate hass, a partir de los datos que recogen las entidades que tradicionalmente prestan asistencia técnica rural en el país, las unidades municipales de asistencia técnica (UMATAS) y facilitar la toma de datos en campo y arrojando luces sobre la creación de nuevos indicadores de desempeño.
Vacío de conocimiento: Deficiente aplicación de métodos e instrumentos de análisis de datos en el proceso de asistencia técnica rural, que permitan definir recomendaciones de actividades, insumos y manos de obra más específicas a la realidad de las distintas asociaciones o individuos de productores agrícolas
Objetivos: 1) Analizar los datos recogidos a través del instrumento de diagnóstico a las fincas RUAT que realizan las Umatas en cumplimiento de su papel de acompañamiento técnico rural; 2) Aplicar las técnicas estadísticas de clasificación y organización de datos más pertinente a dicho instrumento de caracterización; y 3) Determinar la importancia que cumplen para la construcción de indicadores las variables que se recogen en los instrumentos de diagnóstico a las fincas.
Metodología: A partir de la revisión de varios referentes teóricos sobre los pasos necesarios para la creación y selección de indicadores, se siguieron las siguientes etapas metodológicas: Desarrollo de un marco conceptual, selección de variables, normalización de los datos, análisis multivariado y ponderación de la información; otros pasos posteriores como la agregación de la información, análisis de robustez y sensibilidad, podrán ser parte de subsiguientes trabajos.
Resultados y conclusiones: Se encontró que las variables que tuvieron mayor peso en la caracterización y agrupación de los productores fueron las pertenecientes al grupo de las buenas prácticas agrícolas y al de la producción, demostrando que con solo 8 variables se puede tener una buena aproximación a la caracterización de los productores, en lugar de las más de 36 variables de las que se compone el instrumento de diagnóstico denominado Registro de Usuarios de Asistencia Técnica (RUAT)
Diversidad y composición de plantas vasculares en humedales del páramo Rabanal, Boyacá- Colombia
Authors: Cuello-Salinas Magda-Juliana , Galvis-Rueda Manuel 
Published: July 2020

Contextualización: El páramo de Rabanal posee humedales que proveen el recurso hídrico, indispensable para el desarrollo de la economía y de la seguridad alimentaria de la región. Este ecosistema está siendo alterado por la presión que ejercen las diversas actividades antrópicas productivas y económicas, por lo cual, el humedal pierde la capacidad para retener y almacenar agua, facilitando la expansión de especies exóticas que aumentan la sedimentación, reduciendo los niveles de retención y almacenamiento de agua, degradando el suelo y evitando el crecimiento de especies nativas. La vegetación asociada permite la regulación del ciclo hidrológico y favorece una medida de adaptación al clima cambiante.
Vacío de investigación: en los humedales del páramo Rabanal existe escasa información sobre la influencia de la vegetación asociada a los cuerpos de agua que contribuyen a su conservación.
Propósito del estudio: identificar la flora vascular presente en las zonas circundantes a los humedales artificiales del páramo Rabanal.
Metodología: se realizó la caracterización, composición y estructura de la vegetación vascular en zonas circundantes de los embalses Teatinos, Gachaneca I y II en el páramo Rabanal, en municipios de Ventaquemada y Samacá, Boyacá, en cinco salidas de campo se hizo el levantamiento de 32 parcelas dependiendo de las características fisionómicas de la vegetación siguiendo un diseño anidado. El material vegetal se procesó en el Herbario de la Universidad Pedagógica y Tecnológica de Colombia de Tunja (UPTC); la determinación se hizo con el apoyo de claves taxonómicas, bases de datos y expertos. En términos de riqueza, la diversidad se comparó entre los embalses mediante un Análisis de Varianza en rangos o prueba de Kruskall-Wallis.
Resultados y conclusiones: la mayor riqueza de especies de Margalef se presentó en la parcela P2 (5,40), la mayor dominancia de Simpson fue para la parcela P2 (0,95), la mayor diversidad de Shannon corresponde a la parcela P2 (4,39) del Embalse Teatinos, el índice de similaridad de Sörensen indica que los embalses Gachaneca I y II, poseen un 52,63% de similaridad. La evidencia de actividades antrópicas productivas y económicas provoca una pérdida de la vegetación nativa y una fragmentación del ecosistema.
Elaboración de un modelo neuronal artificial para la estimación de la demanda bioquímica de oxígeno en aguas marinas
Authors: Meza Castellar Reynaldo , Gonzalez Salcedo Luis 
Published: July 2020

Contextualización: los modelos neuronales artificiales son modelos diseñados a partir de métodos numéricos denominados Redes Neuronales Artificiales. El uso de estos, como herramienta de predicción de la Demanda Bioquímica de Oxígeno (DBO), ha demostrado diversas ventajas, entre otras, la reducción del tiempo y los costos económicos asociados a este parámetro. La DBO generalmente requiere de 5 a 7 días, así como múltiples reactivos químicos, para poder establecer los niveles de materiales orgánicos en las aguas.
Vacío de investigación: los modelos neuronales artificiales permiten calcular la DBO en tiempo real, a partir de variables fisicoquímicas registradas in situ. A pesar de ello, las redes neuronales artificiales no han sido utilizadas hasta ahora como método de estimación de la DBO en aguas marinas de Colombia.
Propósito del estudio: teniendo en cuenta este aspecto, en la presente investigación se elaboró un modelo neuronal artificial que permite estimar la DBPO en aguas del Mar Caribe Colombiano.
Metodología: para elaborar el modelo fue necesario realizar cinco simulaciones (constituidas por un número de 2 a 3 capas ocultas, y de 5 a 20 neuronas por capa). El desempeño predictivo de cada una de estas se evaluó a través del coeficiente de correlación.
Resultados y conclusiones: los valores más altos de este indicador estadístico (0,937, 0,951, 0,953, y 0,941), se obtuvieron para el modelo que utilizó 3 capas, de 20 neuronas cada una, en sus cuatro etapas de aprendizaje (entrenamiento, validación, prueba, y todos los datos). Estas cifras indican un cercano ajuste entre los datos observados y las estimaciones hechas por la red. Estos resultados demuestran además que la Demanda Bioquímica de Oxígeno puede ser estimada numéricamente, en aguas marinas, a través de modelos neuronales artificiales.
Time-Varying Conditional Co-movement between Inter-Sector Stock Returns: Evidence from Ghana Stock Market
Authors: Appiah Thomas , Forson Abednego 
Published: July 2020

Investors generally exhibit home bias with regards to their investment destinations. To diversify their portfolio, such investors invest in different sectors within the domestic economy. However, such behaviour could be counter-productive in periods of increased co-movement of assets returns. In this paper, we examine the inter-sector stock return co-movement among the major sectors of the Ghanaian economy with the view to shedding some light on the nature of assets return correlations and its implications for portfolio diversification. A sample of 332 weekly observations of stock returns of five major sectors within the Ghanaian economy is used to undertake the analysis. Dynamic Conditional Correlation - Generalized Autoregressive Conditional Heteroscedasticity (DCC-GARCH) techniques are applied to the weekly stock return series from January 2010 to June 2017. The DCC-GARCH model was estimated with correlation targeting and asymmetric DCC. We find dynamic conditional correlation among stock returns of all the sectors, implying that the correlation between the sector returns is time-varying. This result challenges the assumption of constant correlation among stock returns of different sectors in the domestic markets. We also find that the conditional correlation between returns of the various sectors ranges from 0.234 to 0.998, which indicates medium to very high interdependence among the stock returns. Based on the result of this study, we propose that fund managers and investors should not limit their diversification strategies to inter-sector investments since in periods of uncertainty, the ability of the investor to enjoy diversification benefits is seriously undermined.
Dietary Supplementation with Eclipta Alba and Polyalthia Longifolia Foliages on Digestibility, Feeding Behaviour, Blood Profile and Carcass Characteristics of Goats
Authors: Okoruwa M. I. , Okoh P. I. , Akazue R. C. 
Published: July 2020

A feeding trial that lasted for 90 days was carried out to determine the effect of dietary supplementation of Eclipa alba and Polyalthia longifolia foliages on digestibility, feeding behaviour, blood profile and carcass characteristics of goats. A total of thirty two West African dwarf goats of about 7–8 months old were randomly assigned to four treatment diets. Each treatment was replicated four times with two goats per replicate in a completely randomized design. The four formulated treatment diets were, D1 (90% guinea grass with 10% maize straw), D2 (50% guinea grass with 10% maize straw and 40% Eclipta alba foliage), D3 (50% guinea grass with 10% maize straw 20% Eclipta alba with 20% Polyalthia longifolia foliages) and D4 (50% guinea grass with 10% maize straw and 40% Polyalthia longifolia foliage). The results indicated that goats on D1 were significantly (P < 0.05) highest in eating rate, feed conversion ratio, urinary-N-output, urea and creatinine while cholesterol was greater in goats on D2. Crude fiber and ether extract digestibility with white blood cell was significantly (P < 0.05) higher for goats on D3 than other treatment diets. Feed intake, ruminating rate, live weight gain, dry matter with crude protein digestibility, nitrogen intake with retention, red blood cell, total protein, dressing weight and stomach were significantly higher (P < 0.05) in goats on D4 compared with those on D1, D2 and D3. Eating with ruminating time, initial weight, faecal-N-output and most of the carcass cuts with relative organs showed no significant different (P > 0.05) among treatment diets. It could therefore be concluded that supplementation with Eclipta alba and Polyalthia longifolia foliages or their mixture in diets enhance digestibility, feeding behaviour, blood profile and carcass characteristics without any deleterious effect in goats.
Ecological and Health Risk Studies of Heavy Metals in Soils around an Abandoned Battery Factory in Ibadan, Southwestern Nigeria
Authors: Obasi Romanus A. , Madukwe Henry Y. 
Published: July 2020

Heavy metals on the soil around an abandoned battery site at Wofun, Ibadan, Southwestern, Nigeria were studied for their ecological and health risks. Ten soil samples collected from the soil around the abandoned battery sites were analyzed using Inductively Coupled Plasma –Mass spectrometry (ICP-MS). The data were evaluated using indices such as contamination factor, enrichment factor, geo-accumulation index and pollution index to determine the ecological and health risks posed by the heavy metals. The results showed an average concentration of Pb (7274.4), V (190.63), Cu (77.52), Zn (53.08) and Co (53) in a decreasing order. The enrichment factor revealed high enrichment for Co (12.30) at site one (S1), and extreme enrichment of Pb (61.12). Zn, Rb and Mo showed no enrichment in the soil. All the sites exhibited extremely high enrichment of Pb except at S10 where the enrichment of Pb was only severe. The results of Igeo indicated that all the sites were strongly to extremely polluted by Pb while S6 is moderately polluted by Co. The rest of the metals do not constitute any pollution threats. An evaluation of the ecological risk index (RI) revealed that the mean Er for Co (13.95), Cu (8.61), and Zn (0.56) indicate low ecological risk as they are less than 40 (Er <40). Lead (Pb) with Er value of 1818.60 has a very high ecological risk and accounts for most of the ecological risks in the study area. Lead (Pb) being the most toxic and abundant of all the heavy metals analyzed in the study areas was used to evaluate the potential non-carcinogenic health risk for both children and adults. The hazard index which is the sum of the hazard quotients for children is 26.64 suggesting that non-carcinogenic health risk may occur if there is any form of exposure to the soil. The hazard index for the adult (2.87) indicated a significant potential non-carcinogenic health risk in the study area.

Authors: Ibrahim Mosa Mohamed Farouk , Harfoosh Ahmed Kamal 
Published: July 2020

Introduction: Matrix Gla protein (MGP) is a central calcification inhibitor of vascular wall. The biological activation of the calcification-inhibitory protein MGP can be achieved by simple administration of oral vitamin K.
Aim: The study was conducted to assess the effect of vitamin k supplementation on vascular calcification and to evaluate its effect on MGA in hemodialysis patients.
Materials and Methods: Forty adult patients with end stage renal disease (ESRD) on regular hemodialysis sessions, thrice weekly, were enrolled in the study and were randomly assigned into two groups. Vitamin K group consisted of 20 patients were given oral vitamin K at 10 mg after each session of dialysis for a duration of one year. No-Vitamin K group included 20 patients didn’t receive vitamin K. All patients were subjected to the following: Matrix Gla protein (MGP), in addition to, plain digital abdominal x-ray and doppler ultrasound.
Results: After one-year of vitamin K supplementation, a significant increase in MGP levels in Vitamin K group (75.7±26 ng/mL) were noticed. There were no significant changes in CIMT and AACS in Vitamin K group after vitamin K supplementation in compared to their baseline levels, while the CIMT and AACS were significantly increased in No-Vitamin K group in compared to their baseline levels.
Conclusion: Vitamin K supplementation could not stop vascular calcifications but significantly attenuate their progression.
Newtons Laws Explain How Frisbees Fly
Authors: Landell-Mills Nicholas 
Published: July 2020

Newtonian mechanics explain the physics of how frisbees fly. Specifically, a frisbee in horizontal flight with a positive angle of attack (AOA), will fly through a static mass of air each second (‘m/) that it accelerates to a velocity (’a’) downwards, to create a downward force (Force = ma), due to Newtons 2nd law of motion. The ‘equal & opposite’ upward force generated (Newtons 3rd law of motion), provides an upward force and vertical lift. Air goes down and the frisbee goes up. It’s that simple.
There are two airflows: The underside of the frisbee pushes air down. While the curved topside of the frisbee pulls air downwards due to the Coanda effect. This explanation is different to other theories of lift currently available, such as those based on fluid mechanics (Bernoulli and Navier-Stokes) and vortices.
The spin on a frisbee enhances the stability of flight due to the gyroscopic effects. In turn, stability of flight allows the frisbee to generate laminar (smooth) airflows, and thus better lift. The spin itself does not directly contribute towards lift. In addition, airflow vortices account for trick throws, where the frisbee appears to defy normal physics.
So what? This provides new insight into lift and flight not currently found in accepted physics textbooks. The best performing frisbee will be one that maximises the Coanda effect on the topside of the disc; to increase the amount of air displaced down. Newtons laws can explain why a frisbee thrown flat (small AOA) generates better lift and will fly further than a frisbee thrown high, on a parabolic type of path. This explanation of lift can also be applied to airplane wings.
