Representación claroscura: una exploración audiovisual y teórica de la representación del pasado en el cine documental
Authors: Stollbrock Trujillo Gerrit
Published: September 2017

Desde la imbricación entre producción audiovisual e investigación teórica, este artículo parte de la experiencia de realización de un documental sobre el pasado de una planta de cemento en Colombia: La Siberia. Las tensiones entre la construcción narrativa del documental y la inmensidad del archivo desechado conducen a una búsqueda teórica para responder a la iconoclasia propia de la crítica postestructuralista de la historia. Ello conlleva la formulación del concepto de representación claroscura, definida como una representación capaz de hacer visible sus propios límites. Tras poner a prueba su aplicación en el lenguaje del cine documental, en específico en La Siberia, y sugerir su pertinencia para otros contextos de representación del pasado, la investigación teórica conduce finalmente a la formulación de un nuevo proyecto de arte. El conjunto del proceso de investigación, en su diálogo entre experiencia y teoría, es interpretado desde el modelo de abducción propuesto por Charles Sanders Peirce.

Published: September 2017

O dejeto líquido suíno constitui importante fonte de nutrientes ao solo, melhorando suas condições físicas, químicas e biológicas. Suas características variam ao longo do tempo, com o manejo dos animais e pelo sistema de tratamento adotado pela granja. As espécies químicas aniônicas, catiônicas e carbono são as que mais apresentam mudanças em suas concentrações ao longo do tempo. Diante disso o estudo teve por objetivo avaliar a magnitude das concentrações e a evolução de cátions, ânions e carbono nos dejetos líquidos suínos em fase de terminação com sistema de tratamento anaeróbico. O estudo consistiu na coleta do dejeto líquido de suínos de três granjas com sistema integrado de criação, na fase de terminação dos animais, sendo realizadas nas calhas de entrada do dejeto e na saída do sistema de tratamento, ao longo de 120 dias do período de alojamento dos animais. As campanhas foram realizadas mensalmente, a partir do alojamento dos animais. As concentrações de espécies catiônicas e aniônicas foram analisadas em Cromatógrafo de Troca Iônica e o carbono total em Analisador de Carbono Total. Os resultados apresentados mostraram que Cl-, NH4+ e CI não apresentaram diferenças significativas entre as granjas. No entanto, as demais espécies químicas apresentaram diferenças significativas. A esterqueira mostrou-se com alta eficiência na remoção dos íons NO2-, NO3- e baixa remoção para os íons NH4+. Durante o período de terminação dos animais as concentrações dos íons Cl-, NH4+ e Ca+2 aumentaram, enquanto as demais espécies químicas reduziram ou mantiveram suas concentrações.

Authors: Ávalos Ramos M.ª Alejandra , Martínez Ruiz M.ª Ángeles , Merma Molina Gladys
Published: September 2017

El interés de los adolescentes hacia la práctica de actividad física y deportiva en su tiempo libre es escaso. Esta investigación analiza las causas de la práctica o abandono de la actividad física y deportiva en el tiempo de ocio de los adolescentes escolarizados. Se ha utilizado una metodología cualitativa que ha permitido analizar y categorizar sus voces y pensamientos. Los resultados muestran que la salud, la afición y la diversión les mueven a la práctica física, mientras que la ineficiente gestión de su tiempo y las actitudes como la pereza, los miedos y las inseguridades son algunas de las causas aducidas para el abandono. Del estudio se desprende que es necesario un cambio metodológico en el contexto escolar para propiciar una mayor afección hacia una práctica deportiva sostenible.

Published: September 2017

Conocer las características psicomotoras de la población infantil, es esencial para elaborar estrategias adecuadas de intervención educativa y terapéutica, ajustadas a las necesidades de los niños. El objetivo de este estudio fue conocer el perfil y desarrollo psicomotor de los niños españoles de 3 a 6 años. Se llevó a cabo un estudio observacional descriptivo-analítico, en el que participaron 217 niños (edad media=4,15 años; 52,8% niñas). El perfil del desarrollo psicomotor se evaluó mediante la Escala Observacional del Desarrollo-versión breve (EOD-B). Los resultados revelaron una media de desarrollo psicomotor del 81,6% del desarrollo esperado para la edad cronológica, y una prevalencia de retraso psicomotor del 4%. Los rasgos psicomotores con mayor dificultad de desarrollo en la muestra fueron la afectividad (15,6%), la motricidad manual (10,6%) y la motricidad somática (7,3%). Las niñas mostraron menor prevalencia de retraso psicomotor y un desarrollo psicomotor significativamente superior a los niños (p<0,05; p<0,01), así como un desarrollo significativamente superior en motricidad manual y conceptuación-pensamiento (p<0,01; p<0,05). Este estudio aporta nuevas evidencias sobre el perfil psicomotor de los niños españoles en edad preescolar y propone nuevas líneas de actuación educativa y terapéutica.
Estrategia de enseñanza sin errores para el aprendizaje de las habilidades deportivas. Una revisión sistemática
Authors: Camacho Lazarraga Pablo , Calvo Lluch África
Published: September 2017

El objetivo del estudio es revisar y evaluar sistemáticamente la literatura relacionada con la estrategia de enseñanza sin errores para la enseñanza de las habilidades deportivas, con objeto de conocer si cometer errores beneficia o perjudica el aprendizaje y/o el rendimiento. Durante el proceso de búsqueda se consultaron las bases de datos Web of Science, Scopus, SportDiscus With Full Text y PsycInfo, además de otras fuentes de investigación. Se revisaron los títulos, resúmenes, textos completos y criterios de inclusión y/o exclusión para su elegibilidad. Se identificaron 10 estudios prospectivos realizados entre los años 2001 y 2016 que cumplían con los criterios de selección establecidos inicialmente. Los resultados indican que en relación a la fatiga fisiológica, psicológica y robustez al paso del tiempo, son los grupos de aprendizaje sin errores los que en el 83,33% de los casos obtienen resultados positivos en su rendimiento, frente al 16,67% de los grupos de aprendizaje con errores. En general podemos afirmar que los sujetos se benefician si se reduce la  cantidad de información que se les suministra. No obstante, los resultados obtenidos evidencian las ventajas de tener dos sistemas adaptativos a los cambios ambientales: incidentales e intencionales. Estos resultados se deberían analizar con cautela, debido al reducido número de estudios localizados y a la heterogeneidad de los diseños utilizados. Se propone la realización de estudios que comprueben los efectos de estas estrategias en un entorno ecológico, con un diseño longitudinal, un mayor tamaño de las muestras experimentales y diferentes niveles de pericia.

In this work, we proposed a technique in which two-dimensional (2-D) confinement of light is achieved in one-dimensional (1-D) planar waveguide by loading it with a low refractive index material. A waveguide design is based on ZnO/Al2O3 dielectric materials for integrated photonics. These waveguides are capable of propagating TE and TM polarization at 0.633 µm visible light. Based on these waveguide structures, many optical elements such as S-bend, Y-splitter can be realized which will provide a compact platform for integrated optics.

We study numerically the dynamics of a vertical-cavity surface emitting laser (VCSEL) with external optical injection and asymmetrical triangular current modulation. Even if the average current is below the threshold, the VCSEL without optical injection emits irregular optical pulses. External optical injection stabilizes the laser output, reduces the standard deviation of the generated pulses and increases their averaged amplitude. The results of this study make it possible to reduce the threshold current.

Porous silicon posseses a wide range of the unique properties and has good perspectives for photo-sensitive structures for a solar cells new generation. Due to the developed pore system, the area of absorbing surface increases, and also the increased sensitivity expands into the short-wavelength region due to the increased energy band gap of silicon nano-particles and silicon nano-filaments on the walls of the pores. Carbonization of the surface layer of porous silicon makes absorption even more effective. In this case, the spectrum of the solar cell expands into the shortwavelength region due to absorption of the high-energy photons in the wide gap material (SiC). In this study, layers of nanocrystalline porous silicon and porous silicon carbide are used as wide-gap material layers in photosensitive structures. The spectral characteristics of the specular reflectance of these materials are investigated.

This study considers a class of double finite Hankel transforms that describes the transmission of a vortex optical signal through a two-lens system with limited aperture radii in the object and spectral flats. The eigenfunctions of the given transform are calculated for different orders of vortex m. The functions obtained are an orthonormal system of functions, which can help expand an unspecified limited optical allocation with high accuracy. Approximation of optical signals without radial symmetry is also performed in this paper.

Automatic analysis of electroencephalograms (EEGs) is one of the promising areas of research, which results can be used, in particular, to build systems of mental control of objects. The Dynamic Time Warping procedure (DTW) is used in this work for comparing signals representing EEG. An important feature of the problem we are considering is the need for multiple comparison of signals at the stage of machine learning, which requires enormous computational costs. We propose a parallel algorithm that was implemented in C++ using the MPI technology and tested using the resources of the supercomputer complex of Moscow State University “Lomonosov”. The results of its testing on real data showed that the proposed method allows achieving an almost linear speedup and reducing the total calculation time from 29 days to 3.5 hours using 128 processes, which opens the possibility of improving the quality of automatic analysis of electroencephalograms.

In present paper we consider the advantages and disadvantages of case-based reasoning (CBR) approach for knowledge representation of the application domain. One of the CBR shortcomings is the insufficient speed of real-time retrieval of cases, as well as the insufficient relevance of the retrieved cases to the current situation. To solve these problems, we offer the use of genetic algorithm. We propose formal statement of the genetic algorithm to the CBR retrieving stage. The results of the investigation are presented. The major advantage of the genetic algorithm is that it gives a more compact set of retrieved cases extracted which possesses, however, characteristic features of the current situation. This property can be very useful when extracting such cases from big data In conclusion, the perspectives of applying the method for adaptation of cases have been given.

Los prejuicios jurídicos al silogismo: una confusión entre forma y contenido
Authors: Posada Ramírez Gregorio , Duque del Río Federico , Ortiz Salazar María Angélica
Published: September 2017

Este texto argumenta que algunos de los prejuicios y prevenciones al uso del silogismo jurídico, como forma  de razonar o tomar decisiones jurídicas, obedece a una confusión en la comprensión de lo que es un razonamiento silogístico. Independientemente de la actitud con la que se asuma el orden jurídico, ya sea como un conjunto de normas a las que se debe incontrovertiblemente obedecer, o como el progresivo intento humano de conducir las acciones de las personas hacia la justicia, el uso del silogismo jurídico no condena a la religiosidad incontrovertible de las normas, y no castra los ideales de justicia propios del derecho. Para mostrar esto, se ubicará las críticas del silogismo jurídico en el contexto de la discusión positivismo jurídico vs iusnaturalismo jurídico. Se describirá lo que son los razonamientos silogísticos, y cómo estos, una vez incorporados dentro del ámbito jurídico, se especifican como silogismos jurídicos. Finalmente, se argumentará que la censura al silogismo como forma de argumentación jurídica, obedece a la incapacidad de distinguir entre forma y contenido de los argumentos. El uso del silogismo dentro del campo derecho es promisorio, pues es una estructura válida del pensamiento, un esquema de razonamiento eficaz que no es exclusivo de una doctrina o ideología del derecho.

Published: September 2017

在我国经济稳定飞速发展和城市化进程不断加快的社会背景下，未来不断地有大量的农业用地转换成非农用 地，随之而来的征地纠纷也日渐激烈，因增值收益分配不合理而引发的群体性事件也不断发生。征地冲突发生的根源并不 是征地活动的本质，而是被征地补偿所反映出来的土地增值收益的分配。越来越多的农村户籍人口选择在城市居住，同时 不愿意放弃农村户口。随着我国政府政策的不断完善，土地流转速度持续加快，土地征收补偿制度也在不断地完善，但是在 征地补偿中仍然存在着不少的问题。本文将以农土地征收过程中土地增值为切入点分析土地增值收益的分配研究。
Predicting Rehabilitation Success Rate Trends Among Ethnic Minorities Served by State Vocational Rehabilitation Agencies: A National Time Series Forecast Model Demonstration Study
Authors: Moore Corey L. , Wang Ningning , Washington Janique Tynez
Published: September 2017

Purpose: This study assessed and demonstrated the efficacy of two select empirical forecast models (i.e., autoregressive integrated moving average [ARIMA] model vs. grey model [GM]) in accurately predicting state vocational rehabilitation agency (SVRA) rehabilitation success rate trends across six different racial and ethnic population cohorts (i.e., Blacks or African Americans, non-Latino Whites, American Indians or Alaskan Natives, Asians, Native Hawaiians or other Pacific Islanders, and Latinos). Methods: Eleven years of Rehabilitation Services Administration (RSA)-911 case record data (fiscal year [FY] 2004 through 2014) on SVRA employment outcomes were extracted and entered into the ARIMA model and GM to test their predictive performance. Results: The GM was demonstrated to be superior to the ARIMA model in predictive accuracy performance. Remarkably, although the GM (1, 1) 3-year frequency curve projection simulation results (FY 2015–2017) showed a slight upward trajectory in the number of successfully rehabilitated Latinos compared to baseline FY 2014 actual numbers, more drastic downward trajectories were projected for Blacks or African Americans, non-Latino Whites, American Indians or Alaskan Natives, Asians, and Native Hawaiians or other Pacific Islanders. Conclusions: The GM represents a demonstrably capable and promising forecasting tool that could be useful to SVRA leaders, policy makers, advocates, and researchers in simulating predictions that inform future policy initiatives, influence strategic plan development, and help guide the state of the science on future research and development foci. Additional multiple comprehensive demonstration trials, nonetheless, are needed to either confirm or refute the GM’s veracity in national and state predictive accuracy and curve fitting performance.

Las rentas de las exportaciones y la política comercial con oligopolio
Authors: Ávalos Marcos , Ramírez José Carlos
Published: September 2017

Para una industria oligopólica, este ensayo analiza la manera cómo la política comercial puede depender de la naturaleza competitiva de los mercados. Estudiamos los efectos de las fusiones nacionales y extranjeras en la política comercial óptima del país de referencia y en las rentas de las exportaciones y el bienestar interno. Hay cuatro resultados principales: i) se demuestra que si el país de referencia aplica su política comercial óptima, siempre perderá a resultas de una fusión extranjera; ii) cuando el país de referencia aplica su política comercial óptima, una fusión extranjera disminuirá las rentas de las exportaciones; iii) cuando el gobierno responde óptimamente a una fusión interna, ésta no afectará el bienestar nacional, y iv) cuando el gobierno responde óptimamente a una fusión interna, ésta no afectará las rentas de las exportaciones.

Para esto, inicialmente se determinan los equilibrios en estos mercados y, por tanto, se estudia la demanda por dinero y la trayectoria de largo plazo del tipo de cambio real. Estos dos temas se utilizan como fundamentos para analizar los efectos de las desalineaciones cambiarias y monetarias en la inflación. El análisis empírico se realiza a partir de datos agregados y desagregados por tipo de productos de consumo.
Reforma de pensiones y determinantes de la afiliación al seguro social de largo plazo en Bolivia
Authors: Evia Vizcarra José Luis , Fernández Moscoso Miguel
Published: September 2017

En 1996 el sistema de reparto estaba quebrado. La reforma de pensiones de ese año cambió el sistema de manera importante. En el presente trabajo se analiza las razones por las cuales el antiguo sistema estaba en quiebra a mediados de los años noventa; así como las características del nuevo sistema de pensiones, los incentivos que incluye para aumentar la cobertura del Sistema de Seguridad Social Obligatorio (SSO) y los riesgos a los que está expuesto, con particular hincapié en el de insolvencia fiscal. La cobertura del seguro social obligatorio de largo plazo ha sido reducida y si bien el nuevo sistema aumenta dicha cobertura, ésta ha permanecido en un porcentaje muy bajo de ocupados. Se estima una función probit para identificar los determinantes de la probabilidad de estar asegurado antes y después de la reforma, en la que se encontró que algunas variables como las horas trabajadas por día, la antigüedad en el empleo y el género de la persona dejan de ser relevantes para determinar la probabilidad de estar asegurado después de la introducción de la reforma.
Pengaruh Antikoagulan dan Waktu Penyimpanan Terhadap Profil Hematologis Tikus (Rattus norvegicus Berkenhout, 1769) Galur Wistar
Authors: Fitria Laksmindra , Illiy Lia Lavi , Dewi Indah Riwantrisna
Published: September 2017

Darah merupakan komponen penting karena menunjukkan kondisi fisiologis individu. Oleh  karena  itu  darah  menjadi salah  satu  parameter  pokok  dalam penelitian praklinik/ biomedik. Hematologi merupakan ilmu yang mempelajari kondisi sel-sel darah perifer dalam kondisi normal maupun patologis. Parameter pemeriksaan hematologis yang rutin dilakukan antara lain profil eritrosit dan leukosit. Sampel darah yang diterima kadangkala tidak langsung diperiksa karena berbagai alasan. Untuk menjaga supaya kondisinya tidak rusak, maka sampel darah ditambah antikoagulan dan disimpan di dalam lemari pendingin selama beberapa jam hingga beberapa hari. Penelitian ini bertujuan untuk mempelajari profil eritrosit dan leukosit pada sampel darah tikus (Rattus norvegicus Berkenhout, 1769) Galur Wistar yang sehat/normal dengan antikoagulan EDTA atau Heparin dan variasi waktu penyimpanan (0, 6, 18, 24, dan 48 jam). Untuk pembahasan lebih lanjut, data dianalisis secara statistik berdasarkan ANOVA two-factor (P<0,05). Hasil menunjukkan bahwa antikoagulan berpengaruh secara signifikan terhadap profil eritrosit dan leukosit (P<0,05). Nilai profil eritrosit pada sampel darah-EDTA lebih rendah daripada sampel darah-Heparin. Sebaliknya pada pemeriksaan profil leukosit, sampel darah-EDTA memiliki kecenderungan nilai lebih tinggi daripada sampel darah-Heparin. Seiring bertambahnya waktu penyimpanan, jumlah eritrosit, total leukosit, neutrofil, dan limfosit berkurang secara signifikan (P<0,05). Waktu penyimpanan tidak berpengaruh secara signifikan terhadap nilai hematokrit, kadar hemoglobin, jumlah monosit, eosinofil, dan basofil (P>0,05). Disimpulkan bahwa pemeriksaan profil hematologis yang terbaik adalah menggunakan darah tanpa antikoagulan namun harus langsung dilakukan segera setelah sampel diperoleh (sebelum darah mengalami koagulasi). Apabila tidak memungkinkan, maka dapat digunakan EDTA atau Heparin, dan jenis antikoagulan harus dijelaskan dalam pelaporannya. Pemeriksaan darah dengan antikoagulan hendaknya juga tetap dilakukan segera setelah sampel diterima (tidak ditunda).

Authors: Yang Yuhui , Zuo Jianlin , Liu Tong , Xiao Jianlin , Liu Shuanglu , Gao Zhongli
Published: September 2017

Background:

The purpose of this study was to investigate the 3-dimensional (3D) morphological features of the true acetabulum in patients with developmental dysplasia of the hip (DDH).

Methods:

Seventy-nine hips—53 in patients with developmental dysplasia of the hip (DDH) and 36 normal hips—were included in the present study. According to the Crowe classification, 26 hips were graded as Class I, 31 were Class II or III, and 22 were Class IV. The anterior pelvic plane was defined to standardize the measurements in the study. A selected virtual cup component was implanted into the true acetabulum of a 3D pelvic model of each hip. The acetabular anteversion angle, effective center-edge (CE) angle, effective Sharp angle, and thickness of the medial wall were measured to provide morphological indices of the true acetabulum. Acetabular sector angles and the component coverage ratio were measured to provide coverage indices.

Results:

The acetabular anteversion angle increased with the severity of the DDH. Crowe-II/III hips had the smallest effective CE angle and the largest effective Sharp angle. The mean medial wall thickness was greatest in the Crowe-II/III hips (8.72 mm; 95% confidence interval [CI] = 7.52 to 9.92 mm), intermediate in the Crowe-I hips (7.17 mm; 95% CI = 6.24 to 8.11 mm), and smallest in the Crowe-IV hips (6.05 mm; 95% CI = 4.78 to 7.32 mm). The integrated coverage ratio of the Crowe-II/III hips was significantly less than that of the Crowe-I and IV hips.

Conclusions:

The morphological features of the true acetabulum in patients with DDH can be evaluated comprehensively by using 3D implantation simulation. Segmental bone deficiency was prevalent in the dysplastic hips, especially those in the Crowe-II/III group. Both the severity and the individual morphology of the acetabular dysplasia should be carefully considered in preoperative planning.
