Climate change adaptation
Authors: Sterett Susan M
Published: July 2019

This paper contrasts knowledge frames for climate change and displacement. First the paper explains the abstract human rights arguments about displacement in climate change and disaster. In contrast, management and claims under lawsuits about climate change and displacement are place-based. The paper then draws on data about knowledge and management strategies in a particular place in the United States, and on a close reading of legal reasoning in a post-disaster domestic housing case in the United States. The paper relies on interpretive methods. Although legal reasoning is often represented as distinctive in how it transforms stories into decisions, it shares characteristics with other forms of policy reasoning. Institutional reasoning transforms the “existential threat” of climate change into managed parts. The paper argues that intervening concerning climate change and displacement requires shifting from broad claims in the drama of climate change and rights to following tactics logical within particular institutions.
Social capital and disaster resilience in the Ninth Ward
Authors: Roberts Patrick S.
Published: July 2019

The conventional wisdom in disaster management is that communities exhibiting social capital are more likely to bounce back after disaster. This paper examines the link between social capital and resilience to disasters and climate change through an examination of New Orleans’ Lower Ninth Ward neighborhood before and after Hurricane Katrina. Using archives and interviews to examine the neighborhood’s recovery, the paper finds evidence for the existence of social capital and the properties of community resilience in the Lower Ninth Ward before the storm. Social capital and resilience proved to be fragile because the neighborhood was particularly vulnerable and lacked political power. Attempts to use social capital and community resilience alone as part of a strategy to combat climate change should take into account older notions of vulnerability and political power as important ingredients in community well-being.

Este monográfico de la Revista Iberoamericana de Educación reúne trabajos sobre problemas importantes de la didáctica de la lengua y de la literatura relacionados con los diversos elementos que componen su campo de investigación: el sistema didáctico formado por el docente, el aprendiz y el objeto del aprendizaje, que consiste en los usos de la lengua y en las habilidades y conocimientos implicados en la formación del lector literario. La complejidad del objeto de investigación de la didáctica de la lengua y de la literatura hace que los temas que pueden ser estudiados sean numerosos y, al menos aparentemente, heterogéneos. Si nos situamos en el objeto de aprendizaje, podemos constatar la diversidad de habilidades y estrategias que engloba –aunque interrelacionadas–, que se refieren, además, a una gran diversidad de usos. Pero esta complejidad se acrecienta cuando ponemos en relación cada elemento del sistema didáctico con el conjunto, y todo él, con los contextos dentro de los que se sitúa.
Los géneros discursivos y la enseñanza de la composición escrita
Authors: Zayas Felipe
Published: July 2019

El artículo propone el examen de las implicaciones del concepto de género discursivo, tomado de M. Bajtín, para la enseñanza de la composición escrita dentro del marco metodológico de las secuencias didácticas. Además de situar la enseñanza en un marco comunicativo, integra los aprendizajes específicos de habilidades lingüístico-comunicativas dentro de una tarea global que les da sentido. Se destaca de un modo especial la importancia de esta integración en cuanto a los conocimientos explícitos sobre la lengua y sus condiciones de uso. Se aborda de este modo uno de los problemas centrales de la enseñanza de la lengua: la relación entre el aprendizaje de los usos verbales y la reflexión sobre la lengua.

En este artículo nos ocuparemos de la experiencia «Callejeros literarios», una propuesta para desarrollar la educación literaria del alumnado. En primer lugar se explica la génesis de un proyecto colaborativo como este, gestionado y realizado por profesores y asesores sin ningún respaldo oficial, y luego se analizan las bases metodológicas que lo sustentan: el trabajo por proyectos, la educación literaria y la integración de las tecnologías de la información y la comunicación (TIC). Se presenta también, a modo de ejemplo, una muestra de los trabajos realizados por los alumnos. Este tipo de proyectos, que han proliferado en los últimos años, tienen un gran potencial para la renovación de las prácticas didácticas y utilizan las posibilidades de la red para impulsar el trabajo compartido, tanto entre el alumnado como entre el profesorado.
Enseñar (y aprender) a leer y a escribir en primer grado
Authors: González Sandoval Gabriela
Published: July 2019

Las estrategias instruccionales son elementos esenciales de la transmisión del saber-hacer profesional que permiten conocer los «quehaceres ordinarios de la clase» (Chartier, 2000). La investigación realizada gira en torno a la exploración de ese saber-hacer, y del modo en que el mismo se articula con las concepciones pedagógicas subyacentes. En este sentido, nos propusimos describir las estrategias de enseñanza que utilizan cuatro maestras de primer grado de una escuela primaria pública de gestión estatal y analizar sus concepciones de lectura y escritura. Se llevaron a cabo observaciones de las clases de lengua, entrevistas dirigidas a cada docente y a los directivos, además del análisis de los cuadernos del alumnado. Una de las conclusiones globales del trabajo es que la mayor parte de las estrategias de enseñanza analizadas muestran resabios de una pedagogía anclada en lo disciplinario que se expresa en la visión homogeneizadora de la realidad y en el control exhaustivo de los aprendizajes.
Ausencia de una enseñanza reflexiva y sistemática de la oralidad
Authors: Gutiérrez Ríos Yolima
Published: July 2019

Este artículo presenta los resultados finales de una investigación cuya problemática es la ausencia de una enseñanza reflexiva y sistemática sobre la lengua oral en el contexto de la educación media colombiana. En particular, se exponen de manera sucinta las tensiones, aperturas y necesidades relacionadas con la oralidad como actividad del lenguaje (concepto), sus formas de materialización y configuración (manifestaciones) y los usos dados (funcionalidad) en el contexto sociocultural y escolar. Para tal fin, se adoptan dos dimensiones: la instituyente de la oralidad como portadora de nuevas perspectivas teóricas y contextos de aplicación –vinculados a la universalización de los mercados, la democracia, los avances científicos, tecnológicos y comunicativos– junto con la dimensión instituida como portadora de situaciones que permanecen y tienden a perpetuarse a través de un sistema de creencias, significados y reglas de acción, es decir, de concepciones derivadas de la historia y la evolución de las sociedades.

Published: July 2019

Abstract.  Cereals and legumes used as animal feed containing phytic acid which cannot be absorbed by the digestive tract of monogastric animals because phytic acid (C6H18O24P6) is an antinutrient that binds approximately 80% P in feed, also binds to proteins, vitamins and minerals (Mg++, Fe++, Zn++, Mn++, Ca++). Then, one option to overcome this problem is the application of phytase enzymes from various sources, including those produced by bacteria. Phytase enzymes can hydrolyse phytic acid in the feed. This study was aimed to determine the growth phase of Burkholderia sp. HF.7 and optimisation of production of phytase activity from variations of Phytate Production Media (PPM) media. This research used as a descriptive approach. The study design used a completely randomised design (CRD) with a factorial pattern consisting of 2 factors, each variation in phytate sources: calcium (Ca) phytate, rice bran, corn bran, and soybeans. Nitrogen source: (NH4) 2SO4, yeast extract, and peptone. Burkholderia sp. HF.7 Growth phase as a standard for phytase production is the 62-hour stationary phase with an OD value of 2.060 log/cell. The optimum phytase production in the variation of PPM media is soybean-peptone with a protein content value of 46.5 mg/mL and an activity value of 8.20 U/mL under conditions of pH 7 with incubation of 37oC for 62 hours. So, phytase activity produced by PPM of cereal crops has a higher current value compared to PPM Ca-phytate media with low activity value.Keywords: Burkholderia, Phytate, Phytase, enzymes.

This study aims to investigate the effect of certain factors of behavioral aspects on negative emotional states among university students. The behavioral aspects that are selected as independent variables in this study are mobile usage, buying behavior and study habits. On the other hand, the negative emotional states that are discussed in this study is depression, anxiety, and stress. Students (N=377) from Universiti Pendidikan Sultan Idris were selected using stratified sampling and purposive sampling as respondents in this study. Correlation analysis was carried out to briefly inform the reader of the relationship between an independent variable and dependent variable, and also the interrelationship among them. There is a small effect indicated by the correlation coefficient between mobile usage and depression and between mobile usage and anxiety. On the other hand, there is a moderate relationship between mobile usage and stress. As for shopping behavior variable, the results indicated it correlates more with anxiety, followed by stress lastly with depression. Last but not least, there is a significant negative relationship between study habit and all dependent variables. As for among independent variables themselves, the results indicated that there is a significant correlation between that mobile usage with shopping behavior, but not with study habit. Same goes to between shopping behavior and study habit. On the contrary, among dependent variables themselves, the results indicated that there is a significantly high correlation between all of them. Multiple regression analysis is conducted by using SPSS software after testing the assumptions. The results of the regression indicated that the model was a significant predictor of depression, anxiety, and stress. Study habit is a significant contributing factor to reduce depression among university students. Besides that, shopping behavior and study habit are a significant contributing factor to anxiety among university students. On the contrary, mobile usage and study habit are a significant contributing factor to stress among university students.

School performance is the main agenda in school organization to achieving the vision and mission as well as the main objectives of the Ministry of Education. Issues on performance in the context of school organization are based on leadership management. The main issues highlighted are based on leadership in achieving the ultimate goal of the Ministry of Education (MOE). This study examines the leadership among the headmasters and principals in schools in improving the performance of schools in Malaysia. From the concept of leadership, the leadership that forms the leadership of entrepreneurship among teachers in every school leader plays an important role in the education system to deal with changes and challenges. Entrepreneurial leadership is a leader who is classified to achieve the same goal of using entrepreneurial behavior. Hence, this study focuses entirely on entrepreneurial leadership relationship with school performance in Malaysia. Supported by the Model Leader-Member Exchange theory, this study proposes a framework by outlining the factors that exist in entrepreneurial leadership and empowering. A total of 171 school administrators from public schools have participated in this study. Data for this study variables were collected through a self-administered survey. Structural Equation Modeling (SEM) is the main statistical technique used in this study. The findings show that some variables such as entrepreneurial leadership and empowerment are significant in relation to school performance. The findings will contribute to future research that researchers can research deeply on the performance of public or private schools in Malaysia.

As
Turkey uses about 25.7% of energy consumption in residential area and doing
this with natural gas imported from the abroad, production of efficient
insolation materials is important to decrease energy dependence and deficiency.
Due to both waste minimisation and money saving, there are great efforts on
developing new environment friendly insulation materials. In the scope of the
current study, the heat transfer coefficient was acquired by applying the
linear heat conduction coefficient measurement device to find the heat transfer
coefficient of the pomegranate seed sample obtained from various processes for
the production of insolation material. The sample also have been examined with
a two-port vector network analyser to see electromagnetic property. At the end
of the experiment, the heat transfer coefficient of the sample produced from
pomegranate seeds was calculate as k = 0.6115 W/mK. Moreover, it has been found
that the obtained sample performs better than the other insulation materials in
terms of electromagnetic perspective. With this feature of the sample, it has
been found that using as insolation material in the areas with the high
electro-magnetic field can minimize the effect of the harmful electromagnetism
in the place where it is applied.
