GENÉTICA DE LA RESISTENCIA AL COMPLEJO MANCHA DE ASFALTO EN 18 GENOTIPOS TROPICALES DE MAÍZ
Authors: Hernández-Ramos Lervin , Sandoval-Islas José S. , Mahuku George , Benítez-Riquelme Ignacio , Cruz-Izquierdo Serafín
Published: July 2020

El complejo mancha de asfalto (CMA) del maíz (Zea mays L.), inducido por los hongos Phyllachora maydis Maubl., y Monographella maydis Müller & Samuels, es una enfermedad de importancia económica, debido a que provoca severas pérdidas en el rendimiento y deteriora la calidad del forraje. El mejoramiento genético de la resistencia del hospedante a través de la generación de genotipos resistentes representa la medida de control más eficiente para la enfermedad. Se conoce poco respecto a la base genética de la resistencia al CMA, por lo cual se determinaron las aptitudes combinatoria general (ACG) y específica (ACE) de 18 líneas endogámicas S7 mediante el Modelo I de frecuencias fijas de Griffing, bajo el Método II que incluyó las 18 líneas más sus 153 cruzas directas posibles. El diseño experimental fue bloques completos al azar, en 4 ambientes diferentes ubicados en los Estados de Veracruz, Guerrero, Puebla y Oaxaca. Tanto la ACG como la ACE tuvieron efecto significativo (P < 0.01), por lo que, tanto los efectos génicos de dominancia como los de aditividad son importantes en la resistencia a la enfermedad. Sin embargo, la ACG fue 45 veces más grande que la ACE, de modo que los efectos génicos aditivos son más importantes, por lo que diversos genes no alelicos están involucrados en resistencia al CMA en maíz, por lo tanto es posible acumular diversos genes en un solo genotipo mediante métodos de mejoramiento genético. Los híbridos más resistentes fueron los derivados de dos líneas con ACG y ACE negativa. Las mejores líneas para producir híbridos altamente resistentes fueron CML-329, CLRCW-105-B y [M37W/ZM607]. La selección recurrente podría ser el método de mejoramiento más útil para acumular e incrementar los niveles de resistencia a la enfermedad en poblaciones sintéticas o compuestas. Los efectos de dominancia fueron los más importantes en algunas cruzas específicas.

Flower length increased 11 % by SA at 1.0 μM. All SA treated plants flowered 6 d earlier and had higher leaf area compared to control plants.
COMPARACIÓN DE DOS SISTEMAS DE MANEJO DEL CULTIVO DEL CACAO, EN PRESENCIA DE Moniliophthora roreri, EN MÉXICO
Authors: Ortíz-García Carlos F. , Torres-de-la-Cruz Magdiel , Hernández-Mateo Silvia-del-C.
Published: July 2020

Tabasco, México es el principal estado productor de cacao (Theobroma cacao L.) y concentra 70 % de la producción nacional. Moniliophthora roreri, agente causal de la moniliasis del cacao (MC), es la principal limitante parasítica en la entidad, donde ha provocado pérdidas de más de 75 % en la producción, con efectos socioeconómicos y ambientales negativos. Las acciones de manejo integrado de esta enfermedad (MIP) ya han disminuido el efecto del patógeno sobre la producción; sin embargo, es necesario un enfoque más amplio que tenga como finalidad incrementar el rendimiento del cultivo, la solvencia económica del productor y la sostenibilidad, mediante un manejo integrado de cultivo (MIC) que puede evaluarse. El objetivo del presente trabajo fue comparar un sistema de MIC del cacao con un manejo tradicional (MT) en Tabasco, México, a fin de proponer la adopción del sistema más viable. Esta comparación incluyó el efecto del manejo sobre la producción de cacao comercial y la epidemiología de la MC; también se realizó un análisis económico marginal. Hubo diferencias (P = 0.001) en el rendimiento entre el MT y el MIC, con rendimientos promedios de 228 a 1082 kg de cacao seco/ha/año, respectivamente. Se registró un incremento de producción del 374.4 % en el sistema MIC, con respecto al rendimiento obtenido en el sistema MT. La incidencia final de la moniliasis en el MIC fue 16 % y en el MT fue de 80.7 %, con diferencias significativas (P = 0.001). Se redujo la incidencia de la MC en 79.9 % con el sistema MIC respecto a la incidencia obtenida en el MT. El MIC produjo beneficios brutos más altos que el MT, con una tasa de retorno marginal de 177 %, por lo que el MIC es económicamente recomendable.

El objetivo del estudio fue evaluar la variación del contenido de betacianinas, betaxantinas, compuestos fenólicos, flavonoides y vitamina C en once variedades pigmentadas de tuna (Opuntia sp.) en inmadurez hortícola (10 d antes de madurez hortícola; IH), madurez hortícola (MH) y en postcosecha (10 d después de la madurez hortícola; PC). Los niveles de betacianinas (0.21 a 59.18 mg 100 g-1 pf) encontrados fueron superiores a los de betaxantinas (0.12 a 24.07 mg 100 g-1 pf) en las variedades de tuna púrpuras y rojas en los tres momentos (IH, MH y PC), no se encontró información de la variación del contenido de estos pigmentos durante el desarrollo y en postcosecha del fruto. Durante el almacenamiento postcosecha (PC) aumentaron los contenidos de betacianinas (de 0.46 a 49.15 mg 100 g-1 pf), betaxantinas (de 0.57 a 19.91 mg 100 g-1 pf), compuestos fenólicos (de 106.60 a 165.56 mg EAG 100 g-1 pf) y flavonoides (de 1.34 a 11.21 mg EQ 100 g-1 pf) en la mayoría de variedades pigmentas. Los niveles superiores de vitamina C se encontraron en la mayoría de las variedades en inmadurez hortícola, que luego disminuyeron gradualmente al llegar a MH y PC. El almacenamiento postcosecha de los frutos de algunas variedades contribuyó a la pérdida de vitamina C.

Training mothers: feminine vocational education in Italy during Fascism
Authors: Martinelli Chiara
Published: July 2020

Throughout the XX century, the term “feminine vocational education” changed its meaning several times. Were the vocational feminine schools aimed at training skilled industrial workers or at educating perspective high-ranked housewives? This paper aims at answering at this question. For such a pursue, it investigates national and local sources and it analyzes how the field changed during the first ten years Fascism ruled Italy. All the vocational schools were struck by a radical reform and by the efforts the Minister of National Education Giuseppe Belluzzo made for rationalize the field. In such a context, curricula taught in feminine vocational schools changed: more time was devoted to domestic economy and to subjects like literature and foreign languages. As the latter were traditionally included in women’ curricula since XIX century, the issue highlights a relevant links between liberal and fascistic educational policies. However, the increasing role domestic education played shows the regime designed vocational feminine schools not for training skilled industrial workers, but for educating mothers. During Fascism, women workers were called to unskilled and low-paid roles for which no training was need; however, lacks in welfare state and economic crisis made the Regime pursue mothers to work hard for saving money and for elevating people’s living standard.

Este estudo teve como objetivo sistematizar a prática da capoeira para idosos. Participaram do estudo vinte idosas reumáticas, com faixa etária entre 65 a 82 anos da Associação Maringaense dos Reumáticos (AMAR) da cidade de Maringá (Pr.). Contou-se com 12 encontros de sessenta minutos duas vezes semanais. As participantes do estudo nunca haviam praticado a capoeira ou nada similar a modalidade. No entanto, todas eram participantes de um programa de atividade física ofertado para terceira idade. Foi realizada uma sistematização de ensino da capoeira, iniciando com a história da modalidade e iniciação a musicalização. Em relação aos movimentos, partiu-se de uma sequência que atendessem os movimentos corporais numa progressão do mais simples para os mais complexos. Os encontros foram fotografados e filmados. Estes recursos posteriormente foi suporte para a análise dos dados, também foi elaborado um diário de campo para registro das especificidades ocorridas em cada encontro, como evolução de movimentos e melhorias das habilidades motoras, sociabilização entre participantes, cooperação para a realização conjunta de movimentos considerados complexos, memorização de cantos, entre outras competências. A análise dos dados foi realizada mediante os pressupostos teórico-metodológicos da análise de conteúdo de Bardin. Os resultados obtidos no decorrer das vivências corporais com a prática da capoeira promoveram autoconhecimento corporal, identificando as possibilidades e limitações corporais, promoveu melhoras significativas no condicionamento físico das idosas, ampliando benefícios nos aspectos sócio afetivos, cognitivo, nas habilidades motoras e ampliação do processo sociabilizador dos sujeitos.

Published: July 2020

Partindo do pressuposto de que as Lutas são pouco desenvolvidas nas aulas de Educação Física, embora façam parte da cultura corporal, portanto dos conteúdos que devem ser ensinados na Escola, esta pesquisa teve por objetivo aplicar e avaliar uma proposta pedagógica desse conteúdo, pautada na Pedagogia Histórico-Crítica, comparando o conhecimento inicial e final dos alunos. Método: A pesquisa caracterizou-se como descritiva qualitativa. Participaram da pesquisa uma turma de Ensino Médio e uma Professora de Educação Física de uma Escola Estadual do Paraná. Os dados foram coletados por meio de um questionário e através de um diário de campo. O procedimento constou de grupos de estudo, elaboração de material didático, intervenção pedagógica e coleta de dados. Os resultados demonstraram que embora os alunos conheçam diversos tipos de Lutas, o conceito é limitado e muitas vezes equivocado, especialmente relacionando-o à violência. Sobre a prática pedagógica, ao comparar o conhecimento prévio com o conhecimento demonstrado após as aulas realizadas, tendo como referência os objetivos propostos, pode-se verificar uma evolução tanto na dimensão conceitual como nas dimensões atitudinal e procedimental. Concluiu-se que a partir de práticas pedagógicas inovadoras e sistematizadas há grande possibilidade de introduzir o conteúdo Lutas nas aulas de Educação Física.

Authors: Ontaneda Jiménez Diego
Published: July 2020

El artículo analiza la importancia de la educación, la informalidad laboral y el trabajo público para explicar las brechas de ingreso laboral entre provincias del Ecuador. Para ello se utilizan microdatos de encuestas laborales de 2017, y se emplean métodos de descomposición basados en regresiones de función de influencia recentrada. Se encuentran marcadas diferencias regionales en términos de ingreso laboral. Los resultados de la descomposición indican que la educación es la variable más importante que explica las diferencias de ingreso laboral entre las provincias. El análisis también muestra que una parte significativa de las disparidades regionales de ingreso laboral responden a la informalidad laboral y al empleo público.
A national survey of burnout amongst Canadian Royal College of Physicians and Surgeons of Canada emergency medicine residents
Authors: Liu Robin , Van Aarsen Kristine , Sedran Rob , Lim Rodrick
Published: July 2020

Background: In recent years, there has been growing interest in the field of physician wellness and burnout. The prevalence of burnout is non-uniform between medical specialties and is most prevalent amongst emergency medicine physicians. Importantly, burnout can be observed amongst individuals early in their medical careers, including medical students and residents. Despite ample studies in other populations, there is no national perspective of burnout amongst Canadian Royal College of Physicians and Surgeons of Canada (RCPSC)Emergency Medicine (EM) residents.

Methods: Our study surveyed Canadian residents undergoing EM training though the RCPSC via local program directors using an anonymous electronic form. Basic demographic characteristics and residents’ contemplation of suicide were surveyed. The Maslach Burnout Inventory – Human Services Survey (MBI-HSS) for medical personnel was used to assess burnout on three dimensions (emotional exhaustion, depersonalization and personal accomplishment).

Results: A total of 65 valid responses were collected from eight of 14 eligible institutions (response rate = 30%). Respondents are primarily male (58%) and in their postgraduate year (PGY) 1-3 (71%). Overall, 62% of residents met the threshold for burnout according to a widely cited definition of burnout using the MBI-HSS. Additionally, 14% contemplated suicide during their training. There was no statistical significance in burnout rates between male and female responders or between residents in different stages of training.

Conclusion: Our results suggest significant burnout amongst Canadian EM residents. These results point to an important opportunity to better support EM residents during their training to improve wellness and reduce burnout.

Slit-Slide-Sew Bijections for Bipartite and Quasibipartite Plane Maps
Authors: Bettinelli Jérémie
Published: July 2020

We unify and extend previous bijections on plane quadrangulations to bipartite and quasibipartite plane maps. Starting from a bipartite plane map with a distinguished edge and two distinguished corners (in the same face or in two different faces), we build a new plane map with a distinguished vertex and two distinguished half-edges directed toward the vertex. The faces of the new map have the same degree as those of the original map, except at the locations of the distinguished corners, where each receives an extra degree: this is the location of the distinguished half-edges. This bijection provides a sampling algorithm for uniform maps with prescribed face degrees and allows to recover Tutte's famous counting formula for bipartite and quasibipartite plane maps.

In addition, we explain how to decompose the previous bijection into two more elementary ones, which each transfer a degree from one face of the map to another face. In particular, these transfer bijections are simpler to manipulate than the previous one and this point of view simplifies the proofs.

New species of Pseudosperma (Agaricales, Inocybaceae) from Pakistan revealed by morphology and multi-locus phylogenetic reconstruction
Authors: Saba Malka , Haelewaters Danny , Pfister Donald H. , Khalid Abdul Nasir
Published: July 2020

During fungal surveys between 2012 and 2014 in pine-dominated forests of the western Himalayas in Pakistan, several collections of Pseudosperma (Agaricales, Inocybaceae) were made. These were documented, based on morphological and molecular data. During this work, three new species came to light, which are here formally described as Pseudosperma brunneoumbonatum, P. pinophilum and P. triacicularis. These species belong in the genus Pseudosperma fideMatheny et al. (2019) = Pseudosperma clade fideMatheny (2005) = Inocybe sect. Rimosae s.s. fideLarsson et al. (2009). Macro- and micro-morphological descriptions, illustrations and molecular phylogenetic reconstructions of the studied taxa are provided. The new species are differentiated from their close relatives by basidiospore size and colouration of basidiomata. Molecular phylogenetic relationships are inferred using ITS (ITS1–5.8S–ITS2), nrLSU and mtSSU sequence data. All three newly-described taxa likely share an ectomycorrhizal association with trees in the genus Pinus. In addition, five names are recombined in Inosperma, Mallocybe and Pseudosperma. These are Inosperma vinaceobrunneum, Mallocybe erratum, Pseudosperma alboflavellum, Pseudosperma friabile and Pseudosperma neglectum.
Stressors and Coping Strategies Among Successful Female African American Baccalaureate Nursing Students
Authors: Kirkland Mary Lee S
Published: July 2020

ABSTRACT

Interview and descriptive methods were used to investigate the stressors and coping strategies of academically successful African American female baccalaureate nursing students (N = 23) in the three predominately Caucasian universities in South Carolina. The study addressed three questions: 1) What are major stressors for African American female students? 2) Which coping strategies do these students use? and 3) Which coping strategies do these students find to be most successful?

Major stressors identified, both by priority and frequency of occurrence, were academic in nature, followed in descending order by environmental, financial, interpersonal, and personal stressors. Coping strategies used with the greatest regularity and success were active coping (taking action to remove or circumvent the stressor), seeking social support for instrumental reasons (seeking assistance, information, or advice about what to do from someone in a position to help), and seeking social support for emotional reasons (getting sympathy or emotional support from someone). Behavioral disengagement, denial, and alcohol-drug disengagement were reported to be unsuccessful coping strategies in the majority of instances.
IDEOLOGIA, UTOPIA E CRISI DELLA POLITICA
Authors: Montani Guido
Published: July 2020

Political parties inspired by the values of liberalism, democracy and socialism no longer appear to be capable of conceiving long-term projects for their fellow citizens and humanity. After the fall of the Berlin Wall, large and small powers entered into a sordid struggle for world supremacy, sparking both local and global conflicts, and heralding the return of nationalism as a dominant ideology. This essay sets out to demonstrate that the posited â€œend of ideologyâ€ is groundless: traditional ideologies are unable to envisage a future of progress because they passively submit to the ideology of the absolute sovereignty of states and the just war to defend national interests. The future of humanity is threatened by a new arms race â€“ regarding both nuclear and conventional weapons - to which governments are dedicating vast amounts of money; money which should actually be invested in saving the planet from global warming and the sixth extinction of animal species now under way. The path taken by the people of Europe, with the construction of the first supranational Union in history, should be a source of inspiration for formulating the policies necessary to construct a world order based on peaceful cooperation between states and to ensure that all citizens of the world enjoy the same rights of freedom and solidarity that, albeit imperfectly, have been achieved in Europe. Human progress is a utopia that can become a reality.

Desirable cost and removal effectiveness of the adsorbents can be obtained by the use and modification of agricultural waste products. Therefore, in this study rice husk (RH), rice husk char (RHC) and chemically modified rice husk char (CMRHC) were prepared and used as adsorbents for the removal of Congo Red dye from aqueous media under different experimental conditions. It was observed that the adsorption of Congo Red dye was not only affected with the types of adsorbents used but also with other experimental variables such as time, adsorbent dose, dye concentration, pH and temperature. Thermodynamics study indicated that the adsorption of Congo Red dye on the three adsorbents is spontaneous and exothermic process. Kinetics data showed that the adsorption of Congo Red dye on these adsorbents follow pseudo-second order model better than the pseudo-first order model. Equilibrium adsorption data were tested with Langmuir, Freundlich, and Temkin adsorption isotherm models. It was observed that the equilibrium data of RH and RHC were found best fit to the Langmuir adsorption isotherm model whereas that of CMRHC was best fit to the Freundlich and Temkin models. CMRHC showed better efficiency compared to both RH and RHC.

Biomass yield and fodder quality of Napier grass (Pennisetum purpureum) as affected by Pigeon pea (Cajanus cajan) intercrop and planting distance
Authors: Tenakwa E. A. , Cudjoe S. , Ansah T.
Published: July 2020

The study sought to investigate the effect of two planting distances and Pigeon Pea (Cajanus cajan) intercrop on the biomass yield, chemical composition and in vitro organic matter digestibility (IVOMD) of Napier grass (Pennisetum purpureum). The treatments were laid in a 2x2 factorial RCBD. The factors were two planting distances (0.5x0.5 and 0.5x1m) and two levels of intercrop (Pigeon Pea intercrop and sole Napier grass). At 90-days, the grasses were harvested and biomass yield measured. The fodder was separated into leaves and stems for chemical and digestibility analysis in 2x2x2 factorial in CRD. The interaction at all levels was not significant for all the parameters. There was a significant main effect of planting distance, intercrop and botanical fraction on biomass yield, plant height, tiller number and fodder quality. Whilst biomass yield was higher (P=0.02) in the 0.5x0.5m, no significant difference was recorded in the effect of the intercrop. Whilst intercrop affected (P<0.05) IVOMD and ME, botanical fraction significantly affected DM, CP and ME. The leaf fraction had more (P<0.05) DM, CP and ME than the stem fraction. The study revealed that close planting distance enhanced biomass yield whilst Pigeon Pea intercrop and botanical fraction affected fodder quality of Napier grass.

Cardiomyopathy is a serious complication of Human Immunodeficiency virus (HIV) infection. Direct effects of HIV, cardiac autoimmunity, opportunistic infections (OIs), nutritional deficiencies (selenium) and severe immunesuppression have been implemented for HIV related cardiomyopathy (HIVAC) ; Elevated anti-alpha myosin antibodies in HIV infection cause cardiac autoimmunity, selenium deficiency leads to cardiomyopathy, myosite invasion and cytokine release cause myocarditis whereas zidovudine triggers reversible and dose dependent myocyte toxicity.
Political Aspects of COVID-19 Epidemic Crisis in China
Authors: Kashin V. B. , Smirnova V. A. , Aksenov I. V.
Published: July 2020

The global spread of coronavirus infection has given States the task of taking decisive measures to respond quickly and on a large scale to the challenge of existing management systems. China has demonstrated successful mobilization mechanisms to combat the negative effects of the pandemic: the necessary measures have been taken to inform the population and stop panic, control and prevent coronavirus, and mitigate the impact on the economy. However, the weak side was the inability to take priority measures in the face of uncertainty, which did not prevent the development of the epidemic at its initial stage. This provoked a search for those responsible among the Chinese leadership, becoming another source of tension in relations between China and the West. Despite the relative success of the measures taken, the situation in China itself remains tense: it faces challenges to prevent a re-outbreak of infection and to restore the economy in the face of information and economic pressure from the United States. In this context, the authors analyze the features of information support for measures taken in China to combat the spread of coronavirus infection and their impact on the domestic and foreign policy situation.
Comparativa normativa de la Enseñanza de los idiomas extranjeros en la Educación Básica según la LOE y LOMCE
Authors: Falla Falcón Nuria , Aubry Anne
Published: July 2020

La Orden de 10 de agosto de 2007 (desarrollo normativo LOE) establece que el alumnado debía cursar la única lengua extrajera con un horario lectivo que superaba las 4 horas semanales en cada uno de los ciclos. Sin embargo, la Orden de 17 de marzo de 2015 (desarrollo normativo LOMCE) recoge hasta una segunda lengua extranjera y con una carga de docencia lectiva directa de los idiomas superior al doble de la normativa anterior. Además, el mapa de desarrollo curricular en esta última ley presenta los criterios de evaluación de cada uno de los ciclos y su relación con el resto de elementos curriculares, y no tiene como referente los contenidos para todo el desarrollo curricular, como ocurre en la LOE. En este sentido, aunque la tendencia de la enseñanza de las lenguas extranjeras en Andalucía sigue unos patrones muy ambiciosos a través del desarrollo de los currículos de las mismas desde la LOE hasta la LOMCE, prioriza el desarrollo de las destrezas en detrimento de la acumulación de contenidos. Este intento de enseñanza es un gran paso hacia otra dimensión en la forma de adquisición de las competencias clave.
La competencia digital de los estudiantes universitarios latinoamericanos
Authors: Martínez Navarro Jorge Angel
Published: July 2020

La investigación que se presenta es un primer acercamiento al estudio del nivel de competencia digital autopercibida de los estudiantes universitarios en el contexto latinoamericano con una muestra representativa de 5 países de la región. Para la recogida de datos se ha utilizado el instrumento INCOTIC adaptado para el contexto Latinoamericano.

Las variables objeto de estudio son: la alfabetización Informacional (DAI), la alfabetización tecnológica (DAT), la alfabetización multimedia (DAM) y la alfabetización comunicativa (DAC); analizando los datos por países y comparando los resultados para cada uno de ellos en función de la edad y el género.

Se detecta que el país que menor puntuación obtiene en las alfabetizaciones analizadas es Ecuador, siendo Chile y Colombia los países con mejor puntuación. Además, se observan interesantes diferencias al profundizar por género y edad en cada alfabetización. En concreto, la DAI más alta se da en el rango de edad entre los 24-31 años, y la DAT, DAM y DAC se da en el rango de 28-31 años. En el caso de las mujeres, la DAI más alta se da en el rango de edad entre los 20-27 años, y la DAT, DAM y DAC se da en el rango de 28-31 años.

Se espera diseñar las líneas maestras de un Plan de Alfabetización Digital para estudiantes universitarios con propuestas para cada una de las universidades participantes que luego sea el insumo para que los investigadores de cada país puedan contextualizarlos a sus realidades con énfasis en las competencias informacionales, por la importancia que ellas tienen en la prosecución de estudios universitarios y posterior desempeño laboral.
Corporate social responsibility and protection of workers’ human rights: the case of Germany
Authors: Seifert Achim
Published: July 2020

The following Article analyzes recent developments of German law regarding CSR and the protection of human rights in the production sites of foreign subsidiaries and suppliers of German companies. It gives a brief overview on the National Action Plan of the Federal Government, adopted in 2016, analyzes possibilities of a direct enforcement of human rights violations before German courts and gives a survey on some relevant instruments German law uses to promote the respect of human rights by German companies (e.g. CSR transparency and public procurement law). Finally, the current debate on the adoption of a “Supply Chains Act” is briefly assessed. The author argues that the CSR debate in Germany has reached a crossroad with the Federal Government’s initiative for a “Supply Chains Act” since such Act would probably establish a supply chain due diligence and also a delictual liability of German companies for human rights violations caused by a non-compliance with its statutory duties to control its supply chain. However, the outcome of this ongoing debate still is unclear.
El derecho social y los sujetos colectivos: la construcción jurídica fundacional de Otto Von Gierke
Authors: Monereo Pérez José Luis
Published: July 2020

Otto Von Gierke tuvo una gran influencia su época y en particular en el proceso de elaboración del  proyecto de código civil alemán y anticipó elementos importantes de la forma política del Estado Social de Derecho. También de él derivaría una de las grandes corrientes constructoras del Derecho Social que influiría –junto a la determinante de Anton Menger- en la creación del Derecho Social del Trabajo, incorporando una nueva dimensión social en el ámbito de lo jurídico, contribuyendo, así, a la “constitucionalización del Derecho privado”. Esa influencia de Gierke es apreciable en el pensamiento jurídico moderno. Tributarios de él son en gran medida todos los autores partidarios del pluralismo socio-político y jurídico, como Hugo Sinzheimer (su discípulo), H.J. Laski y muy especialmente, E. Ehrlich, el cual defiende la existencia de un Derecho vivo creado por las asociaciones como su orden interno.

Correlacionar as variáveis antropométricas, capacidade funcional e força de preensão manual com a qualidade de vida dos servidores da Superintendência Federal de Agricultura em Goiás. Participaram 61 servidores, com idade 49±2,27 anos. Foram coletados dados referentes a antropometria, esforço físico, capacidade funcional, qualidade de vida e prática de atividade física Apenas 1,6% dos participantes era sedentário. A variável antropométrica de maior inadequação foi a circunferência muscular do braço (95,1%). Houve uma correlação negativa entre a capacidade funcional e o IMC, CC e RCE (p = 0,003; p = 0,001; p < 0,001, respectivamente), e positiva com a preensão manual não dominante (p = 0,048). Apesar da elevada prevalência de prática de atividade física encontrada, a mudança de outros fatores relacionados ao estilo de vida mostra-se relevante para a reversão das inadequações antropométricas e melhora da qualidade de vida dos participantes.
KORELASI PENDIDIKAN KEWARGANEGARAAN MEMBANGUN KARAKTER BANGSA
Authors: Yudhyarta Deddy Yusuf
Published: July 2020

Nilai-nilai luhur yang berakar dari kebudayaan nenek moyang kita, saat ini luntur tergantikan oleh produk-produk perkembangan zaman yang memungkinkan masuknya pengaruh-pengaruh budaya asing yang secara tidak sadar sesungguhnya mulai menggeser eksistensi budaya bangsa Indonesia sebagai karakter di kalangan masyarakatnya sendiri. Kita harus menyadari bahwa karakter menjadi sangat penting bagi suatu bangsa karena ia adalah kombinasi dari kualitas-kualitas khusus masyarakatnya yang akan membuat bangsa tersebut berbeda dari bangsa-bangsa yang ada di dunia ini, apa jadinya suatu bangsa yang tidak memiliki karakter?

Hal-hal yang mungkin terjadi, antara lain: hilangnya identitas nasional, mudah terombang-ambing dalam polemik yang bermuara pada konflik, memungkinkan retaknya semangat kesatuan bangsa, hilangnya semangat kecintaan serta kebanggaan terhadap bangsa, dan mudah dimasuki oleh tujuan-tujuan negatif dari negara-negara adikuasa. Permasalahan karakter bangsa saat ini telah menjadi isu nasional, karena hal tersebutlah yang menjadi penyebab keterpurukan bangsa Indonesia di berbagai bidang kehidupan, sehingga memaksa pemerintah untuk melahirkan adanya kebijakan nasional pembangunan karakter bangsa yang diwujudkan dengan dibentuknya sejumlah lembaga nasional seperti Badan Koordinasi Pembangunan Karakter Bangsa serta Satuan Kerja Pembangunan Karakter Bangsa dari tingkat pusat sampai daerah serta banyak dilaksanakan seminar-seminar yang mengangkat isu karakter bangsa sebagai tajuk utamanya. Efektifkah kegiatan-kegiatan tersebut?

Sertifikasi Pendidik dan Profesionalitas Guru SD Negeri Balirejo Yogyakarta: Antara Legalitas dan Realitas
Authors: Erdawati Sri , Rahman Arivaie , Masriani Masriani
Published: July 2020

Penelitian ini dilakukan untuk melihat dan membuktikan, sejauh mana guru bersertifikasi di SD Negeri Balirejo Yogyakarta merealisasikan keprofesionalannya. Sebab, ketika pemerintah telah menjamin mutu guru yang lulus sertifikasi sebagai guru profesional yang telah teruji kompetensinya serta terpenuhi hak-haknya, maka guru dituntut bekerja maksimal dan profesional demi meningkatkan mutu pendidikan Nasional. Peneliti juga membandingkannya, dengan kualitas guru-guru non-sertifikasi di sekolah yang sama. Penelitian kualitatif ini menjadikan seluruh guru SD Negeri Balirejo Yogyakarta yang berjumlah 9 orang, sebagai subjek penelitian. Teknik pengumpulan data dalam penelitian ini, menggunakan Metode Triangulasi (observasi, wawancara, dan dokumentasi). Teknik deskriptif-analisis, digunakan untuk mengulas dan menganasis data temuan. Hasil penelitian yang diperoleh adalah, bahwa tingkat pencapaian implementasi keprofesionalan guru-guru bersertifikasi masih rendah. Legalitas sertifikasi pendidik, tidak menjamin terciptanya guru profesional. Sebaliknya, kompetensi guru non-sertifikasi belum tentu tidak profesional, realita di lapangan menunjukkan bahwa guru non-sertifikasi sudah ada yang dapat dinilai sebagai guru ideal dan profesional. Untuk menuntaskan problem ini penulis memberikan beberapa rekomendasi: 1). Reinforcement, 2). Reorientasi tujuan, 3). Monitoring dan evaluasi, 4). Self kontrol dan Self correction, 5). Kontrol social, dan 6). Konstribusi.
