El objetivo de esta investigación es analizar los factores pedagógicos y socioeconómicos que inciden en el proceso de enseñanza – aprendizaje en la modalidad de multigrado bilingüe: idiomas sumu-mayangna, en la comunidad de “Fruta de Pan” y en la escuela del mismo nombre, segundo semestre 2007 y primer semestre del año 2008.Es un estudio de tipo cualitativo y las técnicas utilizadas fueron: entrevistas a estudiantes, docentes, padres y madres de familia, líderes comunitarios, técnicos PEBI y subdelegada del MINED. De igual manera se realizaron grupos focales con padres y madres de familia y observaciones en las aulas de multigrado. De acuerdo con los resultados los factores pedagógicos que inciden en el proceso de enseñanza - aprendizaje son la falta de materiales curriculares adecuados a la modalidad multigrado, puesto que los que se usan son para la modalidad regular y monolingüe, la falta de capacitación en la modalidad de multigrado hace que los docentes desconozcan la metodología de multigrado, la infraestructura no es la adecuada para la implementación de la metodología de multigrado, la promoción de la equidad de género se dificulta por la cultura que prevalece en las comunidades indígenas, la práctica de la lengua materna sumu- tuahka se sustituye por la lengua miskitu.Los factores socioeconómicos que influyen en el proceso de enseñanza – aprendizaje son: La situación económica de los padres y madres de familia les hace difícil apoyar a sus hijas e hijos en la compra de materiales escolares debido a que la mayoría se dedica a trabajos agrícolas y por eso la niñez se ve obligada abandonar sus estudios primarios, por cultura indígena hasta la actualidad los padres y madres siguen obligando a sus hijas e hijos a que les apoyen en las labores de campo y domésticas en vez de ir a la escuela, el desconocimiento de padres y madres de familia de la importancia que tiene la educación para la niñez, y la difícil situación económica que atraviesan incide en la manera de apoyar a sus hijos en las actividades de la escuela.

El objeto del estudio fue la evaluación de las prácticas pre profesionales, desde la perspectiva del estudiantado, representantes de instituciones y autoridades universitarias. El enfoque fue cualitativo y por su profundidad, descriptiva, al valorar la opinión de quienes informaron en relación a la vida académica y las prácticas pre profesionales. Es de tipo transversal, semestre del 2009. La información se obtuvo a través de revisión documental, entrevistas y grupos focales. Entre los hallazgos se destacaron aspectos favorables y desfavorables de las prácticas pre profesionales, tales como: el afianzamiento de conocimientos, oportunidad laboral y visión de la realidad laboral, establecimiento de relaciones interpersonales, falta de confianza en sí mismos e iniciativa propia, visualización de éstas como un requisito a cumplir, poca apertura y confianza de las instituciones que inciden de forma negativa en el desarrollo y alcance pleno de los objetivos en este proceso. La carencia de normativas que regulen el proceso, la planificación, acompañamiento, evaluación y retroalimentación son vacíos sustanciales que afectan la finalidad de éstas. La diversidad de formas en que se han realizado las prácticas, vuelve más complejo el proceso por limitaciones económicas y humanas del recinto. En base a los resultados se sugirió la elaboración de una normativa que guíe el proceso de las prácticas pre profesionales, acompañado de la asignación de recursos humanos y económicos.Palabras claves: Prácticas pre profesionales; destreza; habilidades; evaluación.CIENCIA E INTERCULTURALIDAD Volumen 8, año 4 No. 1 Erero - Julio 2011 pp.41-50
Op zoek naar innovatie in het beleidsimplementatieonderzoek: de meerwaarde van ‘Qualitative Comparative Analysis’

Op zoek naar innovatie in het beleidsimplementatieonderzoek: de meerwaarde van ‘Qualitative Comparative Analysis’
De voorbije vier decennia werden er heel wat studies naar de implementatie van beleid uitgevoerd, maar deze hebben vier belangrijke tekortkomingen: (1) onduidelijke omschrijving van de afhankelijke variabele, (2) te weinig inzicht in de ‘kritieke’ onafhankelijke variabelen en te weinig aandacht voor de wijze waarop deze in combinatie met elkaar het beleidsimplementatieproces beïnvloeden, (3) te laag aantal cases en (4) te weinig aandacht voor hypothesetoetsing. Dit artikel geeft aan hoe het gebruik van Qualitative Comparative Analysis (QCA) (Ragin, 1987) een antwoord kan bieden op deze beperkingen. Deze analysemethode tracht de verschillende causale paden die het beleidsimplementatieproces beïnvloeden te identificeren en de condities of combinaties van condities die noodzakelijk of voldoende zijn in kaart te brengen. Hiervoor wordt gebruikgemaakt van Booleaanse algebra. Door deze en andere specifieke eigenschappen kan QCA leiden tot vernieuwende inzichten in beleidsimplementatieonderzoek.

Authors: Tang An-Chieh , He Shi-Yuan , Lee Ming-Kwei 
Published: February 2016

Abstract
In this study, the nanoimprint lithography (NIL) technique used to fabricate III–V compound nanowires was investigated. A silicon mold and thermoplastic polymer mr-I 7010R were used for hot embossing nanoimprint lithography. The mold was patterned by e-beam lithography with two masks exposed with different dosages to reduce the proximity effect. The filling capability and residual layer thickness of the thermoplastic polymer were optimized at the embossing temperature of 125 °C. A 73 nm GaAs nanowire was obtained by the mold coated with an antisticking layer.
Polycyanoacrylates
Authors: Burns Barry 
Published: February 2016

AbstractAlkyl 2‐cyanoacrylate monomers are commonly used as instant adhesives or “superglue,” mainly because of their unique ability to undergo rapid polymerization under ambient conditions on a wide range of surfaces. This article overviews the chemistry and physical properties of these materials, the most common methods of preparation, their mode(s) of polymerization, and typical performance properties. The main performance limitations of alkyl 2‐cyanoacrylate adhesives, such as poor hot strength and resistance to extreme environments (high heat and humidity) are explained in terms of the susceptibility of the polymer to degradation, and how the chemical structure of the polymer directly affects this degradation process. An overview is given of how the performance properties of cyanoacrylate adhesives are modified through the inclusion of various thickeners for viscosity modification, accelerators for cure acceleration, and recent advances in two component cyanoacrylate adhesives. The uses of polycyanoacrylates in medical adhesive applications and for the preparation of nanoparticles for drug delivery are briefly reviewed.
A Network Inversion Filter combining GNSS and InSAR for tectonic slip modeling

Published: February 2016

AbstractStudies of the earthquake cycle benefit from long‐term time‐dependent slip modeling, as it can be a powerful means to improve our understanding on the interaction of earthquake cycle processes such as interseismic, coseismic, post seismic, and aseismic slip. Observations from Interferometric Synthetic Aperture Radar (InSAR) allow us to model slip at depth with a higher spatial resolution than when using Global Navigation Satellite Systems (GNSS) alone. While the temporal resolution of InSAR has typically been limited, the recent fleet of SAR satellites including Sentinel‐1, COSMO‐SkyMED, and RADARSAT‐2 permits the use of InSAR for time‐dependent slip modeling at intervals of a few days when combined. With the vast amount of SAR data available, simultaneous data inversion of all epochs becomes challenging. Here we expanded the original network inversion filter to include InSAR observations of surface displacements in addition to GNSS. In the Network Inversion Filter (NIF) framework, geodetic observations are limited to those of a given epoch, with a stochastic model describing slip evolution over time. The combination of the Kalman forward filtering and backward smoothing allows all geodetic observations to constrain the complete observation period. Combining GNSS and InSAR allows modeling of time‐dependent slip at unprecedented spatial resolution. We validate the approach with a simulation of the 2006 Guerrero slow slip event. We highlight the importance of including InSAR covariance information and demonstrate that InSAR provides an additional constraint on the spatial extent of the slow slip.

AbstractA novel Mini Wind Profiling radar at 205 MHz has been set up at Cochin (10.04°N, 76.33°E), India, with the main objective of studying the dynamics of the Indian summer monsoon. This paper presents the first time validation of this Mini Wind Profiler using collocated radiosonde wind measurements. The wind profiles within 1–6 km altitude range have been validated. The radar wind profiles match very well with the radiosondes both in terms of magnitude and direction and ideally captures the day‐to‐day wind variations. The correlation between radar and radiosonde's zonal and meridional wind is 0.91 and 0.85, respectively. The standard deviation of the difference between radiosonde and radar for zonal wind is found to be 1.95 m s−1 and 1.56 m s−1 for meridional wind. These observations are seen to agree quite well with other established wind profiler radars operating elsewhere in the world. The results show that the 205 MHz Wind Profiler is capable of providing high‐quality wind data, and this could be pivotal for monsoon studies in years to come.

ABSTRACTThe aims of this study were to assess the processing window of hypromellose acetate succinate (HPMCAS) as a polymeric carrier for hot‐melt extrusion, and to investigate the effect of screw configuration and processing parameters on the physicochemical properties of HPMCAS extrudates. The processability was investigated using a Brabender® mixer and a Pharma 11 Twin Screw Extruder. HPMCAS extrudates were characterized with regard to glass transition temperature, true density, yellowness index, crystallinity, morphology, and free succinic acid/acetic acid/succinoyl group/acetyl group content. The specific energy input and mean residence time were also calculated and correlated to the physicochemical properties of final extrudates. Additionally, the effect of the die opening size of the twin screw extruder was investigated. The glass transition temperature of HPMCAS was found to be 137 and 133°C, using dynamic mechanical analyzer and oscillatory rheometer, respectively. HPMCAS demonstrated a shear thinning behavior at all temperatures tested (150, 160, and 170°C). The process conditions, screw configurations, as well as the diameter of die opening significantly affect the amount of free acetic acid and succinic acid. With a modified screw configuration and 1‐mm die, the amounts of free acetic acid and succinic acid from the material processed at 180°C were 0.114% and 0.337%, respectively. Moreover, when the die was removed, the amounts of free acetic acid and succinic acid were further reduced to 0.084% and 0.294%, respectively. In conclusion, we successfully extruded HPMCAS at a temperature as low as 130°C and up to 180°C without any significant thermal degradation.
Was acupuncture developed by Han Dynasty Chinese anatomists?
Authors: Shaw Vivien , Mclennan Amy K. 
Published: February 2016

ABSTRACTAnatomical dissection has begun to reveal striking similarities between gross anatomical structures and the system of nomenclature used in traditional Chinese acupuncture. This paper argues that acupuncture point nomenclature is rooted in systematic anatomical investigation of cadaveric specimens, and that acupuncture points and meridians are purposefully named to reflect observable physical form. Two types of evidence are compared: observations of physical structures based on anatomical dissection, and translation and analysis of original Chinese texts. Evidence is contextualized through in‐depth practical understanding of acupuncture. Points designated as 天 tian (heavenly/superior), 下 xia (below/inferior), 髎 liao (bone‐hole), 飛 fei (flying), 委 wei (bend), and 谿 xi (mountain stream/ravine) are investigated. These acupuncture point names: (a) specify position; (b) reflect function and/or form; (c) indicate homologous structures; (d) mark unusual structures; and/or (e) describe the physical appearance of a deep (dissected) structure by likening it to a homologous everyday object. Results raise intriguing possibilities for developing an understanding of acupuncture points and meridians firmly based in the material and functional anatomy of the human body. Such an understanding has the potential to open new fields of thought about functional anatomy. It also has implications for future investigations into the mechanisms of acupuncture, and gives some insights into the possible origins of this iconic area of Chinese medicine.

Robust Stability Analysis for Systems with Time‐Varying Delays: A Delay Function Approach
Authors: Ma Ming‐Yu , Dong Chao‐Yang , Wang Qing , Ni Maolin 
Published: February 2016

AbstractThis paper is concerned with the robust stability of time‐varying delay systems with structured uncertainties. Stability conditions are provided through a Lyapunov‐Krasovskii functional (LKF) method. The proposed method introduces a linear function of the time‐varying delay to construct the LKF. With this function, two‐dimensional partition is conducted on the integral domain in the derivative of LKF. Quadratic convex combination then is employed to present stability criteria in the form of linear matrix inequalities (LMIs). The method not only exploits the information of delay at different time instants, but also enables the handling of its derivative to reduce conservatism. Numerical examples are given to show the effectiveness of our method.
A LOFAR view on the duty cycle of young radio sources
Authors: Brienza M. , Morganti R. , Shulevski A. , Godfrey L. , Vilchez N. 
Published: February 2016

AbstractCompact Steep Spectrum, Gigahertz Peaked Spectrum, and High Frequency Peak (CSS, GPS, HFP) sources are considered to be young radio sources, but the details of their duty cycle are not well understood. In some cases they are thought to develop in FRI/FRII radio galaxies while in other cases their jets may remain confined within the host galaxy, and some may experience intermittent activity or die prematurely, never reaching the size of large classical double radio galaxies. Studying in a systematic way the presence and the properties of any extended emission surrounding these compact sources can provide firmer constraints on their evolutionary history and on the timescales of activity of the radio source. Remnant emission from previous outbursts is supposed to have very low surface brightness and to be brighter at low frequency. Taking advantage of the unprecedented sensitivity and resolution provided by the Low Frequency Array (LOFAR) we have started a systematic search of new CSS, GPS, and HFP sources with extended emission, as well as a more detailed study of some well‐known of these sources. Here we present the key points of our search in the LOFAR fields and a more in‐depth analysis on the source B2 0258+35, a CSS source surrounded by a pair of large, diffuse radio lobes. In this way, we aim to provide a better census of restarted sources and a better knowledge of the variety of their duty cycle. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Nature of radio feature formed by re‐started jet activity in 3C 84 and its relation with γ ‐ray emissions

Published: February 2016

AbstractRe‐started jet activity occurred in the bright nearby radio source 3C 84 in about 2005. The re‐started jet is forming a prominent component (namely C3) at the tip of jet. The component has showed an increase in radio flux density for more than 7 years while the radio spectrum remains optically thin. This suggests that the component is the head of a radio lobe including a hotspot where the particle acceleration occurs. Thus, 3C 84 is a unique laboratory to study the physical properties at the very early stage of radio source evolution. Another important aspect is that high energy and very high energy γ ‐ray emissions are detected from this source. The quest for the site of γ ‐ray emission is quite important to obtain a better understanding of γ ‐ray emission mechanisms in radio galaxies. In this paper, we review the observational results from very long baseline interferometry (VLBI) monitoring of 3C 84 reported in series of our previous papers. We argue the nature of re‐started jet/radio lobe and its relation with high‐energy emission. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
A possible link between high rotation measure and CSS‐GPS sources
Authors: Pasetto A. , Kraus A. , Mack K.‐H. , Bruni G. , Carrasco‐González C. 
Published: February 2016

AbstractWe report here the study, in the radio band, of a sample of candidates of high rotation measure (RM). The point‐like objects (at kpc scale) were selected by choosing unpolarized sources from the NVSS which show significant linear polarization at 10.45 GHz. Assuming in‐band depolarization, this feature suggests the presence of a very dense medium surrounding them in a combination of a strong magnetic field. Further single‐dish observations were performed with the 100‐m Effelsberg telescope to characterise the SEDs of the sample and to well determine their RM in the 11 to 2 cm wavelength range. Besides, a wideband (L, S, C and X band) full polarisation observational campaign was performed at the JVLA facility. It allows us to analyse the in‐band RM for the most extreme objects. Some Effelsberg results and analysis, and preliminary JVLA results are presented. The observations reveal that sources with young, newly growing, radio components at high frequency (i.e. GPS and HFP sources) are characterised by a really dense and/or a magnetised medium that strongly rotates the polarisation angle at the different frequencies, leading to a high RM.
