Authors: Бурдин Д.А. , Фетисов Ю.К. , Чашин Д.В. , Экономов Н.А.
Published: August 2017

Экспериментально обнаружен и исследован эффект преобразования спектра магнитного шума в планарной магнитоэлектрической структуре Metglas--цирконат-титанат свинца--Metglas. Показано, что узкополосный шум с центральной частотой fN приводит к линейной генерации шумового электрического напряжения на частоте шума и нелинейной генерации шумового напряжения вблизи нулевых частот и в области удвоенной частоты шума. Эксперимент хорошо объясняется теорией смешения магнитных полей в магнитоэлектрических композитах c нелинейной зависимостью магнитострикции ферромагнетика от поля.

Carrier Screening for the Haemoglobinopathies: Past, Present and Future
Authors:   National Haemoglobinopathy Reference Laboratory, Biomedical Research Centre Molecular Diagnostic, Laboratory, Haematology Department, John Radcliffe Hospital, Oxford, UK, Old John , Harteveld Cornelis ,   Department of Clinical Genetics, Haemoglobinopathies Expert Centre, Leiden University Medical Centre, Einthovenweg 20, 2333ZC Leiden, The Netherlands
Published: August 2017

Carrier screening for the haemoglobinopathies has undergone many technological improvements in haematological and molecular diagnostic techniques since the first prenatal diagnoses by DNA analysis in the 1970s by Southern blot analysis enabled the implementation of effective successful prevention programmes for beta thalassaemia involving public education, carrier screening, genetic counselling and prenatal diagnosis in Mediterranean countries. The application of a wide variety of PCR-based molecular diagnostic techniques which allows the detection of the complete range of haemoglobinopathy mutations has led to the establishment of comprehensive national prevention programmes in many developing countries and also in countries such as those in Northern Europe in which the prevalence and heterogeneity of the haemoglobinopathies has been significantly increased by population immigration. Despite the great technological advances in mutation detection, the screening of haemoglobinopathies still requires the combined use of haematological and molecular techniques to arrive at an accurate diagnosis, and requires specialist knowledge of genotype/phenotype relationships because of the multitude of complex phenotypes which result from interactions between genotypes and co-inherited globin gene disorders relationships. The latest technological advances in mutation analysis techniques and the application of some of these for the noninvasive approach of analysis of fetal DNA in maternal blood are anticipated to improve haemoglobinopathy prevention programmes in the future.

El país tiene importantes desafíos en el contexto global y nacional en el escenario de la ciencia, la tecnología y la innovación. Por una parte, la alta producción académica mundial, que hoy está por encima de los 2.400.000 artículos Scopus al año, con un llamado de atención por la difusa calidad científica de los manuscritos y la pertinencia de esta masiva producción (DORA, Declaración de San Francisco de Evaluación de la Investigación1). Por otra parte, es necesario hacer énfasis en la necesidad de contar con capital humano calificado para desarrollar actividades de ciencia, tecnología e innovación. Para el caso colombiano, el Departamento Nacional de Planeación (DNP), informa que ese número es bajo en comparación con el promedio de América Latina:En 2012 se graduaron 6,6 doctores por millón de habitantes, mientras que se registraron en Brasil (70,6) y México (43,7) doctores graduados por millón de habitantes, es decir que Brasil presentó 10 veces el número de personas con doctorado frente Colombia y México 8 veces2.

Las variables de riesgo asociadas no fueron significativas (p=0,05). Conclusión. De acuerdo con los resultados se puede observar que la Leptospirosis es una enfermedad de gran importancia y de elevada seropositividad en el departamento de Boyacá, principalmente en la población que se encuentra constantemente en riesgo ocupacional al trabajar con animales.
La teoría de juegos en la interacción comunicativa entre servidores públicos y receptores políticos / The game theory in the communicative interaction between political actors and its receptors
Authors: Reyes Sánchez Carlos
Published: August 2017

Las interacciones comunicativas entre servidores públicos y receptores políticos pueden ser consideradas como un ejercicio de doble vía, en el que ambas partes son simultáneamente emisoras y receptoras de información, por lo que cada una de ellas responde y reacciona a la comunicación enviada/recibida. Esto genera una cadena de interacciones entre dos o más agentes involucrados, en la cual, de forma continua, sus participantes responden a los estímulos que reciben a partir de estas nuevas reacciones. El presente artículo analiza la interacción comunicativa entre servidores públicos y receptores políticos con base en diversas teorías de la negociación; de esta forma, la teoría de juegos es una herramienta de análisis económico que mejora la comprensión de la interacción política comunicativa.
“Quando sahir de caza, arme-te com o signal da Cruz”: instruções para a rotina de um menino cristão em um manual pedagógico português do século XVIII
Authors: Amaral Giana Lange do , Ripe Fernando Cezar
Published: August 2017

Este artigo tem por objetivo analisar certos enunciados religiosos para o cotidiano da infância masculina presentes no manual pedagógico Escola Nova, Christã, e Politica, Na qual se ensinão os primeiros rudimentos, que deve saber o Menino Christão, e se lhes dão regras para com facilidade, e em pouco tempo aprender a ler, escrever e contar. Publicada em Portugal inicialmente no ano de 1756 a obra de autoria de Francisco Luiz Ameno (1713-1793) foi registrada pelo pseudônimo de D. Leonor Thomasia de Sousa e Silva. Ao enquadrar o manual na categoria de Literatura de Comportamento Social, interessa-me, em particular, verificar as instruções que o autor prescreveu para a rotina de um menino cristão no contexto setecentista português. Nesse sentido, o conjunto das práticas recomendadas foram percebidas, aqui como mecanismos para a produção de máximas morais e de comportamentos socialmente desejáveis, que constituíram modos específicos de ser menino infantil em Portugal no século XVIII.
Mário Pedrosa e a construção do espaço imperial dos EUA sob o capitalismo monopolista
Authors: Andrade Everaldo Oliveira
Published: August 2017

Este artigo busca resgatar o percurso intelectual empreendido por Mário Pedrosa, pensador político brasileiro que, ao escrever dois livros em 1966 – a Opção Imperialista e Opção Brasileira – buscou caminhos de explicação da história brasileira. Uma das questões que pretendemos resgatar e examinar nesse trabalho é a hipótese explicativa internacionalista que elaborou Mário Pedrosa para analisar as grandes linhas de força que levaram o país a uma ditadura militar em 1964. Ele busca articular de maneira original a avaliação global do desenvolvimento do capitalismo dos EUA e sua gênese totalitária. Ele destaca o lugar particular da América Latina como laboratório político dos EUA em particular desde o pós Segunda Guerra. O Brasil é situado em um quadro mundial mais amplo e contraditório, mas nem por isso menos favorável a um salto histórico para além de suas possibilidades imediatas e aparentemente limitadas da submissão ao capitalismo como então se desenhava.

Authors: Hama Abdulla Ahmed , Ali Fatimah Mohammed , Mero Wijdan M S. , Hassan Kalil
Published: August 2017

Hydatid disease is a helminthic infection, caused by the metacestode stage of cestode belonging to the Echinococcus grnulosus (dog tapeworm). The species and strain identification of Echinococcus are of medical importance for strategic control measuring. The present study achieved to determine and compare fertility and biochemical profiles of hydatid cyst fluid isolated from human, cattle, sheep and goat. The human originated cyst has been found to be more fertile (88%), followed by  sheep-originated cyst (85%). The high rate of fertility was found in the liver followed by lungs in all intermediate hosts. However, the statistically significant differences of a biochemical test of cyst fluid among intermediate host were observed just in the uric acid, while the result of biochemical tests Hydatid cyst fluid isolated from liver significantly was higher than that of the lung for the most biochemical tests. The fertility and biochemical parameters value differences directly have related to the location of cyst and strains of E. granulosus. This finding concluded the sheep strain is a predominant strain and responsible for human and animal echinococcosis and sheep is the main intermediate host responsible for the perpetuation of the life cycle of E. granulosus in Sulaimani.

LA REINSTITUCIONALIZACIÓN DE LA EDUCACIÓN SUPERIOR EN VENEZUELA
Authors: Parra-Sandoval María Cristina
Published: August 2017

La aprobación de una nueva Constitución Nacional en 1999 inició un proceso de reestructuración institucional y refundación de la república. En educación superior se difundió el discurso de la inclusión y la igualdad, basadas en la universalización de la educación y la descolonización del conocimiento. No obstante, el modelo ha profundizado las debilidades y carencias del sector y exhibe efectos perversos: existencia paralela de dos sistemas de educación superior; modificación de la plataforma institucional basada en criterios ideológicos, relaciones clientelares y partidistas; imposición de un modelo político-ideológico: socialismo del Siglo XXI; deterioro de la calidad y productividad, en términos de resultados de investigación y del desarrollo de posgrados; fuga de talentos; negación de la pluralidad del pensamiento y de aceptación de la diversidad; presencia de un Estado autoritario, que controla y regula el sector mediante la imposición de planes y decretos, sin participación de las instituciones autónomas.
PROJETO TUNING EUROPEU PARA A EDUCAÇÃO SUPERIOR
Authors: Ferreira Kleyton Carlos , Lima Paulo Gomes
Published: August 2017

O Projeto Tuning inicialmente surgiu na Europa no contexto de reforma da Educação Superior Europeia materializado no Tratado de Bolonha em 1999.  O presente trabalho de caráter exploratório discute o itinerário do Tuning no Espaço europeu e provoca algumas pontuações para reflexão sobre seu delineamento na e para as demandas do mercado, a saber: referência no estabelecimento da escala europeia de competências genéricas e especificas para formação do estudante europeu conforme suas áreas temáticas, uma metodologia de trabalho a partir dos sistema ECTS e a função da aprendizagem, docência, avaliação e rendimento em relação a garantia da qualidade. O artigo conclui que a projeção do Tuning em menor ou maior prazos, consideradas as premissas da ordem democrática e grau de autonomia das universidades, se tornará com menos legitimação se não colocar na agenda de discussões as demandas e expectativas dos cidadãos para além das solicitações do mercado.
UM OLHAR SOBRE A INTERNACIONALIZAÇÃO E GEOPOLÍTICA DO CONHECIMENTO NA AMÉRICA LATINA

com a apologia de organismos internacionais, dentre os quais cita-se o Banco Mundial e referenciais centrados em “socialização e humanização do capital” organizados na geração de novos formatos de universidades e seus currículos, como apontado pelos organizadores do Dossiê, a geopolítica do conhecimento ou como aponta Mollis (2006) a “geopolítica do saber” divide o mundo em duas partes: a) aqueles que produzem o conhecimento por conta de sua hegemonia econômica e cultural e b) os que consomem os conhecimentos dos primeiros, consoante suas métricas e reafirmação da expertise dos modelos hegemônicos transfronteiriços. Os organizadores do Dossiê foram muito felizes na proposição e difusão, por meio dos artigos apresentados, visto a recorrência e já materialização dos modelos internacionais em economias de países em desenvolvimento e sua consoante busca pelo enfrentamento via uma “decolonização” que entre denúncias e anúncios, constroem caminhos para se construir as demandas advindas e localizadas nos Estados-nação periféricos.
A POLÍTICA DE EDUCAÇÃO EM TEMPO INTEGRAL
Authors: Borges Edmar José , Sant’Ana Izabella Mendes
Published: August 2017

Este artigo visa focalizar a política de Educação em Tempo Integral sob a ótica da ideologia neoliberal. A análise se concentrou primeiramente sobre a experiência de ampliação da jornada escolar levada a termo por Anísio Teixeira no estado da Bahia em meados dos anos 50. Em seguida, são analisados os dispositivos teóricos e legais que sustentam o Programa Mais Educação, política do governo federal de ampliação do tempo na escola. Discute-se que o modo de produção capitalista neoliberal se apropria da educação em tempo integral de duas maneiras: transformando a ETI em política corretiva e convertendo a Educação de Tempo Integral como mercadoria ofertada por meio de parcerias com a sociedade civil. Conclui-se que a política de Educação em Tempo Integral, como qualquer outra política pública no contexto atual, tem sido usada para reafirmar ou reproduzir os princípios básicos do Neoliberalismo.

Comparability of Mean Scores of Gifted Students on the Jordanian Version of the Overexcitability Questionnaire (OEQII) Across Gender
Authors: Al-Shayeb Abdelhafez Q.
Published: August 2017

The aim of the present study was to investigate the comparability of the mean scores of gifted students on the Jordanian version of the Overexcitabilities Questionnaire OEQII in light of gender. A cluster random sampling technique was used to collect data from 448 males and females gifted students who are enrolled in the King Abdullah II Schools of Excellence in Jordan. Results of multi-group confirmatory factor analysis clearly indicate that measurement invariance with respect to gender is untenable. Uniform measurement bias was observed in all subscales. Results suggested that the Jordanian version of OEQII failed to display scalar invariance across gender which is a requirement to scores’ comparability. Initial analyses of fitting the model to the data for each subscale suggested that the theoretical common factor structure didn’t display a reasonable fit to the data for any subscale. Results suggested that the Jordanian version of OEQII failed initially to display configural invariance across gender. In light of the results, it is recommended that the mean-level comparisons of OEQII subscale scores across gender should be interpreted with caution. Moreover, re-validating and re- standardizing of the Jordanian version of OEQII was suggested to justify mean scores comparability on its subscales.

Authors: Nawafleh Waleed H. , Alomari Wesal H.
Published: August 2017

This study aimed to investigate the effect of using Fryer teaching model on 7th grade students' acquisition of scientific concepts. The researchers were interested in testing if differences between students’ acquisitions of scientific concepts were dependent on previous achievement. Also important was to test if students' acquisition of scientific concepts correlated with attitudes towards using Fryer model. To achieve the objectives of the study, a quasi-experimental method was used. Two instruments were developed: a test to measure the acquisition of the scientific concepts and a questionnaire to measure students' attitudes. The study sample consisted of 72 students who were divided into two groups: one (n=37) studied science using Fryer model; the other (n=35) used the traditional method. At the end of the experiment, concepts acquisition test was administered to both groups; while the attitude scale was administered to the experimental group. The results revealed that there were statistically significant differences (p < 0.05) in the acquisition of scientific concepts in favor of the experimental group; and the previous achievement in favor of high achievers. There was an interaction effect between method and previous achievement. The results also revealed a statistically significant correlation between the acquisition of scientific concepts and attitudes towards learning using Fryer model among 7 graders.
Saudi Arabia Science Teachers' Trends in Science Teaching Practices of Teaching Related Scientific Activities According to their Supervisors' Prospective and the Supervisors Estimates of The Importance of Such Practices
Authors: Aldahmash Abdulwali H.
Published: August 2017

This paper investigated the Trends in Science Teaching Practices in-classroom science related activities among general education science teachers in Saudi Arabia from their supervisors’ perspectives. In addition, the supervisor's point of view about the importance of scientific related instructional activities was assessed. The data were collected through a validated questionnaire (19 items), which was administered to a random sample of 60 science supervisors (32 males, 28 females) from various parts of the Kingdome of Saudi Arabia. The results revealed that supervisors judged classroom activities of science teachers as teacher-centered rather than student-centered. As for supervisors’ estimates of the importance of teaching activities, the results indicated that they believed that the most important teaching activities were: developing the skills of science processes, and "impementing experiments to verify the information, and providing students with correct scientific ideas. The results showed that the least important activities were those that made the students active participants in the learning process. It was concluded that science supervisors were inclined to traditional activities that made the teacher and not the student the central core for the learning process.

The first group comprised the nine-year olds (19 children), the second group comprised the ten-year olds (22 children), the third group comprised the eleven-year olds (52 children), the fourth group comprised the 12-year olds (43 children), and the fifth comprised the 13-year olds (61 children). The results showed that the anaerobic capacity level improved during the stages of growth. The level of improvement achieved in 13-year old children was the highest compared to the other age-groups (P S 0.000). This improvement was not at a steady rate. It occurred through booms that coincided with growth which appears in practice through the evolution of not only the level of values on the amount of effort, but also in the level of some related motor skills. It showed a positive correlation between the values of the anaerobic capacity level, the time of running 100 meters and vertical jumping (p S 0.01). Accordingly, this phase can be considered one of those booms. Key words: anaerobic capacity, (Running-based Anaerobic Sprint Test (RAST), Omani children, the 100 meters running, vertical jumping.

Authors: Michaeel Emtanuos
Published: August 2017

The Brief Multidimensional Students' Life Satisfaction Scale (BMSLSS) is a self-report measure developed to assess life satisfaction among students in five specific domains: family, friends, school, self, and daily life. The purpose of the current study was to develop an Arabic version of this measure and to investigate its psychometric properties with Syrian secondary students as well as university students. With a sample of (N=1604), several methods were used to estimate the reliability and validity of the measure. The results showed satisfactory test-retest reliability and internal consistency coefficients. Also, the results provided evidence for the convergent and divergent validity. Further evidence for the construct validity of the instrument was provided by studying the inter-correlations of its five subscales as well as the correlations of these subscales with the subscales of the entire instrument. At the same time, validity was supported by the correlations of the five subscales with achievement. In sum, the findings of this study show that the psychometric properties obtained from administering the instrument to a sample of secondary school and university students meets acceptable levels. Recommendations were made to conduct further psychometric studies upon the Arabic version of BMSLSS and to administer this version in cross- cultural studies.
The reliability and validity of a scale through the comparison between the traditional method and the Rasch model
Authors: Ibrahim Mikail , M. Elazzabi Osama Omar
Published: August 2017

The present study addressed the issue of reliability and validity of scale through the comparison between the traditional method and the Rasch model, which is seen by statisticians as the best method to psychometrically validate the scale and test its properties. Researchers have demonstrated the failure of traditional statistical methods to take into account the characteristics of the items and people when testing the reliability of the scale as well as respondents. They usually turn to alpha Cronbanch to examine the internal consistency of the scale without taking into consideration that alpha Cronbanch has been affected by external factors such as the length of the scale. However, the Rasch model that is relatively considered to be modern statistics, is not affected by external factors especially the length of the scale, even a short scale might be more reliable than the long one. Moreover, the Rasch model can also be used to investigate various types of validities such as content validity, construct validity, and criterion validity. Interestingly, the Rasch model is also a powerful statistics tool used to determine the contribution of the items and people in the total reliability of the scale. For example, the variable map is used to examine the extent to which the items adequately target the respondents taking into account the difficulty of items and ability of the subjects. Nevertheless, the traditional methods normally calculate the uniqueness of the scale by focusing on the sum of squares and these methods do not offer standard errors for each item to determine the accuracy of the measurement. Hence, the researchers suggested in this paper that favorability of the Rasch model in testing scales’ reliability and validity was recommended compared to conventional statistical methods.

Published: August 2017

This study aimed at determining the professional development needs of mathematics teachers in Saudi Arabia. The sample of the study contained 643 teachers and 39 supervisors of four districts of education across Saudi Arabia. The survey addressed two domains of professional development: content knowledge in mathematics, and pedagogical content knowledge. The study found that, in the domain of content knowledge for professional development, the most frequently occurring topics were as follows: Topological concepts and their applications, spherical geometry and its applications; mathematical problems solving; mathematical logic, reasoning, and proof; and, limits and continuity and their applications. In the domain of pedagogical content knowledge, participants defined areas of deficit across thirteen topics. Included in these were: Mathematical teaching for students with special needs; mathematical teaching for gifted students; lab use in teaching mathematics, etc. Two-way ANOVA indicated that there were significant differences in means of mathematics teachers’ needs for professional development in favor of supervisors vs. mathematics teachers in the pedagogical content knowledge domain alone. While there were no significant differences in the means of the need for professional development for mathematics teachers related to their teaching grade level or to the interaction between job and grade level in both domains.

This study aimed at examining the environmental literacy among students of the Faculty of Education at Yarmouk University. The researchers designed a four-part instrument for measuring environmental literacy consisting of: environmental knowledge, attitude towards the environment, environmental practices, and a concern for environmental issues. The sample of the study consisted of 430 male and female students in the second semester of the academic year 2010/2011.The findings revealed that the subjects' level of environmental knowledge and attitudes towards the environment are below the accepted educational standard 75% with a statistically significant difference ( = 0.05), and that the level of environmental practices matches the accepted educational standard. The findings also showed a statistically significant difference in the mean scores on environmental knowledge scale due to gender in favor of female, while no differences were found due to the variables of year of study and specialization. A statistically significant difference was also found in the means of the subjects' responses on attitudes towards the environment scale due to specialization while no differences were found due to year of study and gender. Unlike specialization, both year of study and gender were found to cause a statistically significant difference in the means of the subjects' responses to the concern for environmental issues scale in favor of female respondents. None of the variables of the study was found to make any statistically significance differences in the means of the subjects' responses to the environmental practices scale.

In this study, the appropriateness of existing quality standards and their use in practice in educational organizations were discussed. The study shows how the quality standard of TQM and QMTL and the possibility of their articulation to develop a holistic model can contribute to change this situation. The study alsoinvestigated whether this standard is an adequate basis for quality development in organizations. To implement a quality system in an educational organization, four main steps are necessary: context setting, model adaptation, model implementation/adoption, and quality development. Each step should be performed with a broad range of actors to raise awareness and consensus. To facilitate this process and to develop a quality system for an organization, the use of the holistic model for the description of quality approaches was recommended. Since the model is very generic, more research is necessary, especially to find specific solutions to different contexts of usage (e.g., for schools). Additionally, research has been initiated to analyze the differences and adaptation requirements for different countries and regions to include cultural aspects. Finally, a variety of tools is being developed to support this process, such as the initial choice of a quality approach or the choice of quality instruments. For the future, it can be expected that a variety of tools will be available to support this process and to integrate quality into a broad range of educational organizations.
