Rechtliche Institutionen als Vermittlungsort der „Politik der Straßen“: Eine Auseinandersetzung mit der Rechtsprechung der Krise in Portugal
Authors: Vestena Carolina Alves
Published: August 2019

Massenproteste gegen Austerität haben viele europäische Länder in den Jahren nach der Finanzkrise gekennzeichnet. Diese Auseinandersetzungen haben ebenfalls Interaktionen zwischen sozialen Bewegungen und rechtlichen Institutionen geprägt. Basierend auf dem Beispiel der „Rechtsprechung der Krise“ in Portugal wird in diesem Artikel eine theoretische Reflexion entwickelt, die sowohl die Grenzen des Rechtsmobilisierungsansatzes aufzeigt, als auch Forschungsansätze für eine materialistische Interpretation der Rechtsform anbietet. Dieser Ansatz verdeutlicht den widersprüchlichen Charakter der Anwendung von rechtlichen Strategien durch soziale Bewegungen.
Exofacial phospholipids at the plasma membrane: ill-defined targets for early infection processes
Authors: Galle Jan N. , Hegemann Johannes H.
Published: August 2019

The eukaryotic plasma membrane (PM) consists largely of phospholipids and proteins, and separates the intracellular compartments from the extracellular space. It also serves as a signaling platform for cell-to-cell communication and an interaction platform for the molecular crosstalk between pathogens and their target cells. Much research has been done to elucidate the interactions between pathogens and host membrane proteins. However, little is known about the interactions between pathogens and membrane phospholipids, although reports have described a contribution of phospholipids to cell recognition and/or invasion during early infection by diverse pathogens. Thus, during adhesion to the host cell, the obligate intracellular bacterial pathogens Chlamydia spp., the facultative intracellular pathogen Helicobacter pylori and the facultative aerobic pathogen Vibrio parahaemolyticus, interact with exofacial phospholipids. This review focuses on several prominent instances of pathogen interaction with host-cell phospholipids.
Structure, dynamics and interactions of large SRP variants
Authors: Wild Klemens , Becker Matthias M.M. , Kempf Georg , Sinning Irmgard
Published: August 2019

Co-translational protein targeting to membranes relies on the signal recognition particle (SRP) system consisting of a cytosolic ribonucleoprotein complex and its membrane-associated receptor. SRP recognizes N-terminal cleavable signals or signal anchor sequences, retards translation, and delivers ribosome-nascent chain complexes (RNCs) to vacant translocation channels in the target membrane. While our mechanistic understanding is well advanced for the small bacterial systems it lags behind for the large bacterial, archaeal and eukaryotic SRP variants including an Alu and an S domain. Here we describe recent advances on structural and functional insights in domain architecture, particle dynamics and interplay with RNCs and translocon and GTP-dependent regulation of co-translational protein targeting stimulated by SRP RNA.
Towards More Realistic Modeling of Linguistic Color Categorization
Authors: Correia José Pedro , Ocelák Radek
Published: August 2019

The ways in which languages have come to divide the visible spectrum with their color terminology, in both their variety and the apparent universal tendencies, are still largely unexplained. Building on recent work in modeling color perception and categorization, as well as the theory of signaling games, we incrementally construct a color categorization model which combines perceptual characteristics of individual agents, game-theoretic signaling interaction of these agents, and the probability of observing particular colors as an environmental constraint. We also propose a method of transparent evaluation against the data gathered in the World Color Survey. The results show that the model’s predictive power is comparable to the current state of the art. Additionally, we argue that the model we suggest is superior in terms of motivation of the principles involved, and that its explanatory relevance with respect to color categorization in languages is therefore higher. Our results suggest that the universal tendencies of color categorization cannot be explained solely in terms of the shape of the color space induced by our perceptual apparatus. We believe that only by taking the heterogeneity of the phenomenon seriously can we acquire a deeper understanding of why color categorization takes the forms we observe across languages.
Competitive pseudo-ELISA based on molecularly imprinted nanoparticles for microcystin-LR detection in water
Authors: Garcia Yadiris , Canfarotta Francesco , Smolinska-Kempisty Katarzyna , Piletsky Sergey A. , Pereira Eduardo
Published: August 2019

Microcystins (MCs) are dangerous cyanotoxins for the public health, and microcystin-LR (MC-LR) is one of most toxic, dangerous, and frequently found in water bodies. Typically, the detection of MCs is carried out by means of competitive ELISAs which, however, need special precautions for handling and storage, due to the stability of the antibodies used in this test. Molecularly imprinted nanoparticles (nanoMIPs) represents more robust and cost-effective alternative to antibodies. In this work, we developed a competitive pseudo-ELISA based on nanoMIPs (which are used in place of natural antibodies), for the detection of microcystin-LR (MC-LR). This pseudo-ELISA showed a linear response towards MC-LR, showing high affinity and low cross-reactivity against another analogue toxin (microcystin-YR). The analytical recovery of MC-LR in the analysis of water samples by the proposed pseudo-ELISA was 96 %–130 % and the limit of detection was 2.64 × 10−4 nM. The obtained results suggest that this competitive pseudo-ELISA could have high potential in the detection of toxins, due to its rapid, sensitive and accurate detection of toxin in water samples.

Authors: Sommerfield Lesley M. , Harrison Craig B. , Whatman Chris S. , Maulder Peter S.
Published: August 2019

Injury prevention (IP) programs have been developed to reduce sports-related injuries and risk factors for injuries and to improve athletic performance in youth. This review aims to provide an overview of IP programs in youth females, males, and both sexes and then provide recommendations for those working with female athletes. Independent IP training programs with a high session attendance, of greater than 20 minutes in length, and completed 2–3 times per week have shown the greatest benefit. In addition, programs with multiple components, progressed according to the technical competency of the participants, are the most beneficial.

Continuous Leak Location in Gas-Filled Steel Pipe Based on Optimum Wavelet Analysis of Leak AE Signal
Authors: Wang Shaofeng , Dong Lili , Wang Jianguo , Wang Hailing , Xu Guang , Hong Jun
Published: August 2019

This study is investigates how to reconstruct the continuous leak acoustic emission (AE) signal to precisely locate the leak source on a gas-filled steel pipe based on cross-correlation location theory. Thus, in this article, the determination method for the optimum mother wavelet was proposed. The frequency distribution of the continuous leak AE event was firstly extracted through wavelet transform (WT) with optimum mother wavelet. In the considered frequency range, the WT coefficients were further used to reconstruct the raw continuous leak AE signal. The correlation-based location experiments were finally carried out to evaluate the performance of the proposed method. The results show that the location errors of the leak source were decreased by some 10 % compared with those achieved by only using the raw AE signals. Thus, improvement verifies the validity of choice of the optimum mother wavelet. Meanwhile, it is also founded that, whether the reconstructed signals or raw signals were used, the localization accuracy of the leak source using the speed of the T wave is greater than that using the speed of the L wave and theoretical acoustic speed under the same symmetry of the AE sensors with reference to the leak source. Therefore, defining the acoustic speed with the speed of the T wave was recommended to use on-site for detection of the continuous leak source on a gas-filled steel pipe.

Selección de proveedores priorizando criterios sostenibles para productos: un enfoque de AHP en compras públicas peruanas
Authors: Cordero Torres Bernardo
Published: August 2019

This paper focuses on sustainable public procurements that seek to minimize negative environmental impacts and improve positive social impacts, which require significant changes within the market reality of a country. In the case of Peru, legislation establishes the requirement that sustainable criteria be integrated into public procurement suited to the needs for the procurement of goods and services. In this way, the problem that this study seeks to resolve relies on technical non-observance to verify compliance with current regulations in force within the supplier selection process that consider sustainability criteria. Therefore, the application of the Hierarchy Analytic Process (AHP) is suggested as a heuristic solution alternative. This selection model makes it possible to improve the administrative process by increasing objectivity and reducing cognitive bias. To demonstrate this, the Analytic Hierarchy Process will be verified in a case study concerning the selection of LED lighting suppliers for a public institution.

Maternal Voice and Infant Sleep in the Neonatal Intensive Care Unit
Authors: Shellhaas Renée A. , Burns Joseph W. , Barks John D.E. , Hassan Fauziya , Chervin Ronald D.
Published: August 2019

BACKGROUND:

Approximately 10% of US newborns require a NICU. We evaluated whether the NICU acoustic environment affects neonatal sleep and whether exposure to the mother’s voice can modulate that impact.

METHODS:

In a level IV NICU with single-infant rooms, 47 neonates underwent 12-hour polysomnography. Their mothers were recorded reading children’s books. Continuous maternal voice playback was randomized to either the first or second 6 hours of the polysomnogram. Regression models were used to examine sleep-wake stages, entropy, EEG power, and the probability of awakening in response to ambient noise during and without voice playback.

RESULTS:

After epochs with elevated noise, the probability was higher with (versus without) maternal voice exposure of neonates staying asleep (P = .009). However, the 20 neonates born at ≥35 weeks’ gestation, in contrast to those born at 33 to 34 weeks, showed an age-related increase in percent time awake (R2 = 0.52; P < .001), a decrease in overall sleep (R2 = 0.52; P < .001), a reduction in rapid eye movement sleep bouts per hour (R2 = 0.35; P = .003), and an increase in sleep-wake entropy (R2 = 0.52; P < .001) all confined solely to the 6 hours of maternal voice exposure. These associations remained significant (P = .02 to P < .001) after adjustment for neurologic examination scores and ambient noise.

CONCLUSIONS:

Hospitalized newborns born at ≥35 weeks’ gestation but not at 33 to 34 weeks’ gestation show increasing wakefulness in response to their mother’s voice. However, exposure to the mother’s voice during sleep may also help protect newborns from awakening after bursts of loud hospital noise.
The Increment of Short-term Variability of Repolarisation Determines the Severity of the Imminent Arrhythmic Outcome
Authors: Smoczynska Agnieszka , Beekman Henriëtte DM , Vos Marc A
Published: August 2019

Ventricular remodelling can make the heart more susceptible to ventricular arrhythmias like torsades de pointes. Understanding the underlying mechanisms of initiation of ventricular arrhythmias and the determining factors for its severity has the potential to uncover new interventions. Beat-to-beat variation of repolarisation, quantified as short-term variability of repolarisation (STV), has been identified as an important factor contributing to arrhythmogenesis. This article provides an overview of experimental data about STV in relation to the initiation of torsades de pointes in a canine model of complete chronic atrioventricular block susceptible to torsades de pointes arrhythmias. Furthermore, it explores STV in relation to the severity of the arrhythmic outcome.

Resumo Objetivo Analisar os sinais e sintomas apresentados por médicos residentes das clínicas cirúrgicas e anestesiologia expostos à fumaça cirúrgica. Métodos Estudo de coorte prospectivo realizado com médicos residentes expostos a fumaça cirúrgica em um hospital universitário. Houve um acompanhamento durante 17 meses dos residentes ingressantes nos anos de 2015 e 2016, que atendiam aos critérios de estar regularmente matriculado na residência de clínica cirúrgica ou anestesiologia e não ser tabagista. O instrumento de coleta de dados foi composto de dados sociodemográficos e acadêmicos e dos sinais e sintomas relacionados com a inalação da fumaça cirúrgica, citados na literatura. A análise de dados ocorreu de forma descritiva e inferencial, por testes estatísticos e medidas de efeito. Resultados A amostra foi composta por 39 residentes, cuja maioria era do sexo masculino (56,4%) e idade abaixo dos 30 anos (74,3%). Prevaleceram residentes da ginecologia e obstetrícia (30,8%), seguidos de cirurgia geral (28,2%) e anestesiologia (20,5%). Ardência na faringe (p=0,030), náusea e vômito (p=0,018) e irritação dos olhos (p=0,050) incidiram ainda no primeiro ano de residência. O risco de desenvolver ardência de faringe foi 7,765 vezes (p=0,019) no sexo feminino em relação ao masculino. Conclusão Os sinais e sintomas analisados incidiram em até 12 meses do início da residência e o risco de apresentar ardência de faringe foi maior no sexo feminino, o que indica a exposição aos riscos da inalação da fumaça cirúrgica e, portanto, a necessidade de adoção de medidas de proteção individuais e coletivas.

Resumo Objetivo Compreender como é desenvolvido o cuidado de enfermagem no acondicionamento da prótese dentária de idosos hospitalizados. Métodos Trata-se de uma pesquisa descritiva e qualitativa. A coleta de dados foi realizada no período de setembro a outubro de 2018, por meio de entrevistas com 35 profissionais que compunham a equipe de enfermagem dos setores da unidade de terapia intensiva e da enfermaria de um hospital universitário de Salvador, Bahia, Brasil. Os dados foram analisados por meio da técnica de Análise de Conteúdo Temática. Resultados Foi possível compreender que há um descompasso no cuidado com as próteses dentárias, pois houve relato de divergente formato de acondicionamento entre os profissionais e ainda insuficiente registro sobre essa assistência. Foi possível perceber um aspecto positivo quando, pela ausência de material para guarda da prótese, houve estímulo para uma adaptação ao cuidado, que permitiu a diminuição de perdas da prótese no ambiente hospitalar. Conclusão O cuidado da equipe de enfermagem com a prótese dentária de idosos hospitalizados apresenta lacuna, sinalizando uma necessidade de maior atenção nesse instrumento de reabilitação do idoso.
Horizontal stress increase induced by deep vibratory compaction
Authors: Massarsch K. Rainer , Wersäll Carl , Fellenius Bengt H.
Published: August 2019

Compaction by vertically or horizontal oscillating probes increases not only the soil stiffness but also the horizontal effective stress. An important, but often neglected, consequence is that compaction also causes preloading of the soil. The change in horizontal stress following vibratory compaction can be measured independently by two in situ methods – a cone penetration test (CPT) and a flat dilatometer test (DMT). Values of sleeve resistance (CPT) and horizontal stress index (DMT) can be determined prior and after compaction. In this work, five case histories reported in the literature where different vibratory compaction methods were used (dynamic compaction, vibroflotation, VibroWing, TriStar and resonance compaction) were re-analysed. For each test site, the change in CPT cone resistance and sleeve resistance was determined and compared with the increase in horizontal stress index from DMTs. The preloading effect due to vibratory compaction was estimated using empirical correlations.
Influence of initial cracks on the frequency of a 60-year-old reinforced-concrete box beam
Authors: Shen Dejian , Liu Xingzuo , Zhou Baizhong , Zeng Xuan , Du Jun
Published: August 2019

Cracking is a common form of damage in reinforced-concrete (RC) beams. Cracks affect the frequency and deflection of RC beams. Although a model for the natural frequencies of RC beams with one or two flexural cracks has been proposed, a study of the effect of numerous initial flexural cracks on RC beams is still lacking. In the present study, the frequency and deflection of a 60-year-old RC box beam with four initial flexural cracks were tested, and the natural frequency of the RC box beam was theoretically analysed using Rayleigh's method. Theoretical and test results showed that: (a) the natural frequency and stiffness of the RC box beam with four initial flexural cracks decreased by 39·0 and 62·8%, respectively; (b) the model for the natural frequency of the RC box beam with N initial flexural cracks was proposed based on the theoretical and test results; (c) the deflections of the RC box beam with four initial flexural cracks obtained from Branson's method and Eurocode 2 were both close to those from the test; and (d) Branson's method for calculating the deflection of beams with four initial flexural cracks was conservative.
Discussion of the safety, serviceability and suitability of bus rapid transit services
Authors: Akbulut Kubilay , Bezgin Niyazi Özgür , Kici Aydin
Published: August 2019

Bus rapid transit maximises the capacity of mass transit serviced by buses. Dedicated transit ways, specially designed stations and buses, customised fare-collection methods and dispatch management are instrumental to achieve this capacity maximisation. The increased mass transit capacity provided by bus rapid transit services (BRTSs) is comparable to transit capacities provided by urban rail transit systems. Due to their perceived simplicity of implementation and implementation costs, the adoption of bus rapid transit is favoured by municipalities for mass transit in a number of cities around the world. BRTSs provide a fast and effective solution to increased transit demand that surpasses the limits of ordinary bus services in mixed traffic. However, BRTSs have inherent limitations in terms of control, capacity, safety, serviceability and urban well-being. These limitations result in significant service failures and reduced safety. This study raises some concerns and discusses some aspects of bus rapid transit with regard to its safety and serviceability. The study then investigates the types and occurrences of adverse events such as accidents, incidents and service failures experienced in the BRTS in Istanbul since its inauguration and assesses the adverse events that have occurred.
Pharmacological Npt2a Inhibition Causes Phosphaturia and Reduces Plasma Phosphate in Mice with Normal and Reduced Kidney Function
Authors: Thomas Linto , Xue Jianxiang , Murali Sathish Kumar , Fenton Robert A. , Dominguez Rieg Jessica A. , Rieg Timo
Published: August 2019

Significance Statement

Hyperphosphatemia is common in the later stages of CKD and treatment options are limited to dietary phosphate restriction and oral phosphate binders. The sodium-phosphate cotransporter Npt2a, which mediates a large proportion of phosphate reabsorption in the kidney, might be a good therapeutic target for new medications for hyperphosphatemia. The authors show that pharmacologic inhibition of Npt2a in mice not only causes a dose-dependent phosphaturia, reductions in plasma phosphate levels, and suppression of parathyroid hormone, but also increases urinary excretion of sodium, chloride, and calcium. It does this without affecting urinary potassium excretion, flow rate, or pH. The results show for the first time that a novel Npt2a inhibitor has potential as a treatment for kidney disease-related hyperphosphatemia.

Background

The kidneys play an important role in phosphate homeostasis. Patients with CKD develop hyperphosphatemia in the later stages of the disease. Currently, treatment options are limited to dietary phosphate restriction and oral phosphate binders. The sodium-phosphate cotransporter Npt2a, which mediates a large proportion of phosphate reabsorption in the kidney, might be a good therapeutic target for new medications for hyperphosphatemia.

Methods

The authors assessed the effects of the first orally bioavailable Npt2a inhibitor (Npt2a-I) PF-06869206 in normal mice and mice that had undergone subtotal nephrectomy (5/6 Nx), a mouse model of CKD. Dose-response relationships of sodium, chloride, potassium, phosphate, and calcium excretion were assessed in response to the Npt2a inhibitor in both groups of mice. Expression and localization of Npt2a/c and levels of plasma phosphate, calcium, parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF-23) were studied up to 24-hours after Npt2a-I treatment.

Results

In normal mice, Npt2a inhibition caused a dose-dependent increase in urinary phosphate (ED50 approximately 21 mg/kg), calcium, sodium and chloride excretion. In contrast, urinary potassium excretion, flow rate and urinary pH were not affected dose dependently. Plasma phosphate and PTH significantly decreased after 3 hours, with both returning to near baseline levels after 24 hours. Similar effects were observed in the mouse model of CKD but were reduced in magnitude.

Conclusions

Npt2a inhibition causes a dose-dependent increase in phosphate, sodium and chloride excretion associated with reductions in plasma phosphate and PTH levels in normal mice and in a CKD mouse model.
A Dynamic Factor Model of the Yield Curve as a Predictor of the Economy
Authors: Chauvet Marcelle , Senyuz Zeynep
Published: August 2019

In this paper, we propose an econometric model of the joint dynamic relationship between the yield curve and the economy to predict business cycles. We examine the predictive value of the yield curve to forecast future economic growth as well as the beginning and end of economic recessions at the monthly frequency. The proposed nonlinear multivariate dynamic factor model takes into account not only the popular term spread but also information extracted from the level and curvature of the yield curve and from macroeconomic variables. The nonlinear model is used to investigate the interrelationship between the phases of the bond market and of the business cycle. The results indicate a strong interrelation between these two sectors. The proposed factor model of the yield curve exhibits substantial incremental predictive value compared to several alternative specifications. This result holds in-sample and out-of sample, using revised or real time unrevised data.

Writing with children: a chance of co-authorship in ethnographic research
O CONCEITO DE EXPERIÊNCIA EM MICHEL FOUCAULT
Authors: Valerio López Maximiliano
Published: August 2019

O conceito de experiência se apresenta, na obra de Foucault, como uma constelação integrada por três problemáticas intimamente vinculadas entre si: os jogos de verdade, as relações de poder e as formas de subjetividade às quais estes jogos dão lugar. Estes elementos são veiculados a través de dispositivos heterogêneos (proposições científicas, procedimentos administrativos, estruturas arquitetônicas, etc.) que abarcam tanto o âmbito do dito como do não dito. Tais dispositivos configuram uma “experiência histórica” singular, na qual o ser (o sujeito) se pensa a si próprio e se toma como objeto de ação moral. No entanto, toda a obra do autor está perpassada por uma tensão entre a possibilidade de, por meio de minuciosos estudos históricos, estabelecer os limites dessa experiência histórica, e um exercício propriamente filosófico a través do qual se tenta fazer experiência do próprio limite, quer dizer, realizar uma experiência trágica capaz de colocar em entredito a própria experiência e as formas de subjetividade à qual ela está ligada.

Palavras chaves: Experiência histórica, experiência trágica, poder, saber, subjetividade, dispositivo.

Integración social en estudiantes universitarios de primer año
Authors: Hernández Rosell Yariel , Pérez Pérez Leire
Published: August 2019

La integración social es uno de los componentes fundamentales para el ajuste de los estudiantes a los contextos de la Enseñanza Superior (ES). Este trabajo tiene como objetivo describir la percepción que tienen hombres y mujeres estudiantes universitarios de primer año sobre su integración social al finalizar el primer semestre lectivo. Se aplicó la Escala de Integración Social en la Educación Superior (EISES-R) a 152 estudiantes universitarios de primer año cuyas edades estaban comprendidas entre los 17 y 40 años (Mdn=18.5). El 50 % eran hombres y el 50% mujeres. Tras realizar un análisis de varianza (ANOVA) de un solo factor (sexo), los hombres obtuvieron significativamente mayores puntuaciones medias que las mujeres en equilibrio emocional. Las mujeres obtuvieron puntuaciones significativamente más elevadas que los hombres en las relaciones con la familia. Los resultados encontrados son coherentes con hallazgos previos de la literatura donde se informa que el estado emocional y el apoyo familiar recibido por los estudiantes universitarios tienen un papel importante en su ajuste y bienestar psicosocial y se relacionan con variables tales como la integración en el grupo de iguales, amigos/as, el rendimiento académico y el nivel de aspiraciones. Ambas variables podrían tener un papel significativo diferenciador por sexo como predictores del ajuste y adaptación a la ES, así como en el diseño e implementación de pautas de intervención ante el fracaso o abandono en la ES.

Habilidades predictoras de éxito en el aprendizaje inicial de la lectura y su relación con dos métodos de enseñanza
Authors: Marí Sanmillán Mª Isabel , Gil Lario Mª Dolores , Ceccato Roberta
Published: August 2019

El estudio de los factores que influyen en la adquisición de la lectura facilita la detección temprana de las dificultades del aprendizaje lector. Destacan como habilidades predictoras: el conocimiento fonológico, el conocimiento alfabético y la velocidad de denominación. Todas ellas se adquieren a lo largo de la escolaridad pero no tienen el mismo grado de implicación en las distintas fases del aprendizaje lector. Esto parece depender, en parte, del método de enseñanza de la lectura utilizado. Los objetivos de este estudio han sido identificar y analizar las habilidades implicadas en el inicio de la lectoescritura en Educación Infantil que predicen el nivel de comprensión lectora en Educación Primaria, y conocer el peso diferencial que la conciencia fonológica, la velocidad de nombramiento y otras habilidades implicadas en el proceso lector tienen durante los primeros años de instrucción en función del método empleado. Para ello se realizó un estudio longitudinal en el que participaron 130 alumnos de colegios de Valencia y Castellón. El 52% fue iniciado con un método fonológico-sintético y el 48% con un método global. Se tomaron medidas en 2º de Educación Infantil, 3º de Educación Infantil y 1º de Educación Primaria. Se utilizó el test RAN para medir la velocidad de nombramiento, la Batería BIL de Inicio a la Lectura y el Test de Comprensión Lectora ACL.  El modelo de ecuación estructural ha mostrado que en ambos métodos la velocidad de nombramiento a los 4 años tiene un efecto significativo en las variables relacionadas con el inicio de la lectura, evaluadas a los 5 años, las cuales a su vez influirían en la comprensión lectora de dichos niños a los 6 años. Esto indica que la velocidad de nombramiento constituye el cimiento del proceso de codificación fonológica sobre el que se asienta el proceso lector.

Posiblemente sea una de las competencias transversales más comunes a las diversas profesiones, da lo mismo que se trate de actividades sociales, técnicas o artísticas, siempre hay un antes que orienta la acción: programar lo que se pretende hacer, trabajar con un plan, pensar de antemano el proceso a seguir, establecer un diseño previo de la actividad o producto a realizar. En este artículo se presenta el resultado de las diversas decisiones que como docentes deberemos ir adoptando tanto en lo que se refiere a la planificación macro (la configuración del Plan de Estudios) como a la planificación micro (los programas docentes de las materias) (Zabalza, 2004); la propuesta docente para la asignatura “Trastornos de desarrollo” perteneciente al plan de estudios del Grado de Educación Infantil de la Universidad de Granada. En esta vía, para analizar su grado de adecuación, se presentará un estudio consistente en un análisis de las Guías docentes publicadas en las páginas web de diferentes universidades españolas, en el campo de la “Atención a la Diversidad”, concretamente en la materia “Trastornos del desarrollo”.

La gamificación se ha revelado recientemente como una de las metodologías de enseñanza más eficiente en el alumnado mostrándose útil en todos los niveles educativos. Distintas investigaciones le otorgan beneficios como el aumento de la motivación, la mejora del estado de ánimo y el fortalecimiento del vínculo entre otros. Sin embargo, una de las propiedades que más se mencionan es su capacidad para “reiniciar” el reloj de la atención del alumno: la clave es el aprendizaje colectivo, una forma atractiva de recordar nuevos contenidos. También se han documentado beneficios para el profesor, ya que los juegos otorgan un valioso e inmediato feedback de los conocimientos del alumnado. En este trabajo se presenta una experiencia educativa basada en la introducción de la herramienta de gamificación “Kahoot” correspondiente a una asignatura obligatoria del Grado de Maestro en Educación Infantil. Los resultados demuestran el interés y la buena acogida que ha tenido la gamificación en el aula, mostrando junto a altos niveles de motivación un aumento de la asistencia a clase.
Removal of lead in water using activated carbon prepared from Acacia catechu
Authors: Lakshmikandhan K , Ramadevi A
Published: August 2019

The adsorption of Pb (II) on bicarbonate-treated Acacia catechu carbon (BTACC) and commercial activated carbon (CAC) was investigated to assess the possible use of this adsorbent for Pb (II) removal from aqueous solutions. The results obtained from batch studies showed that 98% Pb (II) adsorption for BTACC occurs within 4 h of contact time, within a pH range of 4–10 and a carbon dosage of 100 mg with initial Pb (II) concentration of 10 mg∙L-1, whereas for CAC 52% Pb (II) adsorption occurred within 5 h of contact time and a narrow range of pH 5 and carbon dosage of 100 mg.   Adsorption followed pseudo-second-order kinetics for both carbon sources, with the mechanism of adsorption being intra-particle diffusion and film-diffusion. The best fitting adsorption isotherm for both BTACC and CAC were the Langmuir, Freundlich and Temkin models. Surface characteristics were studied using FT-IR, SEM, EDX.
Smallholder willingness to pay and preferences in the way irrigation water should be managed: a choice experiment application in KwaZulu-Natal, South Africa
Authors: Chipfupa U , Wale E
Published: August 2019

Efficient and sustainable utilization of irrigation water is the key to realizing the objective of enhancing agricultural productivity and commercializing smallholder irrigation farming. Valuing and recognizing the scarcity of irrigation water is essential for its sustainable use. Using cross-sectional data from 328 smallholders in and around Makhathini and Ndumo-B irrigation schemes in KwaZulu-Natal Province, the study aimed to assess smallholder farmers’ preferences for the way irrigation water resources should be managed and their willingness to pay for irrigation water. This was done employing a choice experiment method. The results suggest the need for irrigation water pricing to reflect irrigation intensity. They also show that improving agricultural production and productivity, with market access can enhance farmers’ willingness and ability to pay for irrigation water. The need to consider multiple uses of irrigation water for sustainable utilization of water resources is evident, while supporting women smallholders will have a positive impact on their willingness to pay for irrigation water. The paper recommends a shift towards on-farm volumetric water pricing in the irrigation schemes. The schemes should also have clearly defined boundaries and enforceable rules on collective use of water. The design of irrigation infrastructure should integrate other uses of irrigation water such as domestic and livestock purposes. Consequently, there is a need for further research to ensure that irrigation water prices reflect the marginal value of irrigation water use. Policies should address factors that inherently result in gender differences in terms of access to productive resources which negatively affect sustainable water utilization.
Organophosphorus flame retardants in surface and effluent water samples from the Vaal River catchment, South Africa: levels and risk to aquatic life
Authors: Chokwe TB , Mporetji SM
Published: August 2019

The occurrence and risk assessment of seven organophosphorus flame retardants (OPFRs) in surface water samples within the Vaal River catchment in South Africa were investigated. Wastewater treatment works effluents as the potential sources of OPFRs in surface water were also analysed. In surface water, tris-(chloro-propyl)-phosphate (TCPP) – the total of the three TCPP isomers studied, and tris-(2, 3 dibromo-propyl)-phosphate (TDBPP) were the most abundant OPFRs, with mean concentrations of 276 ng/L and 227 ng/L; respectively. In effluent water samples, the most abundant OPFR was TCPP with a mean concentration of 700 ng/L. A high detection frequency (> 80%) was observed for six of the seven OPFRs with tris-(1, 3- dichloro-propyl)-phosphate (TDCPP) detection frequency being the lowest at 17%. Assessment of risk to aquatic organisms using risk quotients based on measured environmental concentrations (MEC) and predicted no-effect concentrations (PNEC) ranged from no significant risk (for algae, daphnia and fish) to low potential for adverse effects (for algae and fish).

O objetivo deste artigo foi apresentar instrumentos teóricos-metodológicos que temos utilizado e (re)construído em nossas experiências de atuação solidária, neste caso, vividas no contexto da disciplina Construção de Projetos Sociais Multidisciplinares, da Universidade de Brasília, a partir da narrativa dos/as participantes envolvidos/as no desenvolvimento dos projetos sociais intulados: Revitalização da Escola Flor de Laranjeira (em Brasília) e Combate à Intolerância Religiosa (em Salvador). A pesquisa qualitativa com delineamento de pesquisa-ação fundamentou a prática; e a pesquisa narrativa fundamentou a construção de informações para a análise das experiências, entendida como as lembranças que a pessoa tem de uma situação vivida que a impactou. As narrativas, analisadas com base nos pressupostos da análise temática dialógica, geraram  dois eixos vinculados aos significados atribuídos à experiência de atuação solidária: modo de execução e consequência. A análise das narrativas dos/as estudantes demonstrou que os contextos formativos, construídos na disciplina, afetaram seus posicionamentos de si, no sentido de considerar, com mais propriedade, os outros escopos sociais e os contextos com os quais/nos quais interagiram, favorecendo a construção de identidades profissionais solidárias. Com isso, entendemos que a inovação da atuação extensionista está em evocar e/ou permitir a construção de posicionamentos preponderantes de colaboração, que evidenciam um agir de troca intencionalmente solidário, que tende a gerar alegria, saúde mental e sentimento de dever cumprido, como evidenciado nos relatos dos/as estudantes.
