Resolución de conflictos colectivos, comportamiento sindical, y dinámica legislativa y jurisprudencial en materia laboral en el postconflicto en Colombia
Authors: López Moreno Juan Pablo , Villamil Garzón Edwin Mauricio 
Published: April 2019

El presente artículo hace un recorrido por la crisis que afronta el modelo de negociación colectiva en Colombia y que ha traído como consecuencia el aumento del número de tribunales de arbitramento convocados por año y el incremento en los tiempos para la resolución de conflictos de origen laboral. En la segunda parte del documento se hace una aproximación a dos fenómenos que impactan directamente las relaciones laborales en el país: la fragmentación sindical y el crecimiento de la membresía de afiliación a organizaciones sindicales. En la tercera sección se realiza un análisis del proceso de internacionalización de los conflictos colectivos laborales en Colombia en la última década, especialmente, abordando la evolución de las quejas ante el Comité de Libertad Sindical (CLS) y las recomendaciones de la Comisión de Expertos en Aplicación de Convenios y Recomendaciones (CEACR) de la OIT. En la última, parte del artículo se muestra la dinámica de la agenda legislativa frente a temas laborales en el Congreso de la República en el período 2010-2016, así como las tendencias en materia de fallos por parte de la Corte Constitucional entre los años 1991 a 2016. A algunos de los elementos mencionados se intenta hacer un acercamiento en el presente documento. De manera específica, en la primera sección se analiza brevemente la crisis en el modelo de resolución de conflictos en Colombia, centrado en la incidencia de los tribunales de arbitramento y en lo complejo y tortuoso que es emitir un laudo arbitral en nuestro país. En la segunda parte se analiza de manera pormenorizada el impacto que tiene en las relaciones laborales la debilidad del sindicalismo criollo, se realiza un acercamiento a un fenómeno que vive el movimiento de trabajadores en Colombia y es que crece en materia de afiliación, pero pierde capacidad de negociación y poder en general. En la tercera parte se muestra un diagnóstico en torno al incremento de la conflicitividad laboral a nivel internacional, especialmente en dos esceanrios de la OIT el Comité de Libertad Sindical (CLS) y en la Comisión de Expertos en Aplicación de Convenios y Recomendaciones (CEACR). Finalmente, en la cuarta sección se presenta un informe de las tendencias de los fallos en materia laboral de la Corte Constitucional entre 1991 y 2015, asi como de las tendencias y el dinamismo legislativo en el ultimo quinqenio.

Abstract

Introduction
The aim of this study was to design and evaluate the psychometric properties of an instrument for understanding female adolescents’ reproductive and sexual self-care behaviors.

Methods
A methodological study was conducted. In the qualitative phase, individual in-depth interviews were performed to develop the initial questionnaire. In the quantitative part, the psychometric properties of the questionnaire were evaluated.

Findings
The initial questionnaire with 128 items was reviewed by the research team and taking into account the cut-off point 1.5 for the item impact and 0.62 for the content validity ratio (CVR), the number of questions fell to 82 items. S-CVR and S-content validity index (CVI) rations were 0.83 and 0.91, respectively. Exploratory factor analysis led to 74 items in seven dimensions. The alpha Cronbach’s coefficient for the whole questionnaire was 0.895 and the intra-cluster correlation coefficient was 0.91.

Conclusion
The questionnaire developed in this study is reliable and valid for assessing female adolescents’ sexual and reproductive self-care.
An Input Shaping Control Scheme with Application on Overhead Cranes
Authors: Alghanim Khalid , Mohammed Abdullah , Andani Masood Taheri 
Published: April 2019

Abstract
A new optimization technique is developed to generate a step-input acceleration function for an input shaping harmonic system. This approach is integrated into an overhead crane model for a rest-to-rest maneuver with standard and nonstandard maneuver settings. The proposed method guarantees the satisfaction of the system constraints and desired final conditions, while it minimizes the system sensitivity to crane cable-length variations. The minimal system sensitivity is achieved through an optimization algorithm that provides zero vibration and a minimum integral of system sensitivity over a continuous range of crane cable length. Numerical simulations are conducted to demonstrate the feasibility of the proposed shaper in eliminating the residual vibration at the end of a programmed maneuver. Sensitivity analyses are also performed to verify the robustness of the new shaper. In comparison to the previous shapers, the new methodology is significantly less sensitive and can effectively handle different arbitrary maneuver times.
Kurdish Emirs in the 16th-Century Ruus Registers
Authors: Dehqan Mustafa , Genç Vural 
Published: April 2019

Abstract
Sharaf Khān, author of the Sharaf-nāma, is the most energetic early modern champion of Kurdish history. One problem with the standard account of Sharaf Khān is that it organizes Kurdish history according to the author’s own classifications, rather than according to the administrative entities of the overlord empires, the Ottomans and Safavids; and that Sharaf Khān had access only to certain sources which are specific to the principalities. This indicates that one must be careful to use all claims of Sharaf Khān about particular Kurdish emirs, because not all that pertains to the understanding of 16th-century Kurdish emirs is included in the Sharaf-nāma. One way of resolving this inconsistency is to refer to the Ottoman archives. What we want to emphasize in this paper is the importance of the ruus registers for Kurdish history, which, we think, is less widely recognized. In what follows, we shall deal with the Kurdish materials given in the ruus registers.
Learning to navigate – how desert ants calibrate their compass systems
Authors: Grob Robin , Fleischmann Pauline N. , Rössler Wolfgang 
Published: April 2019

Abstract
Navigating through the environment is a challenging task that animals cope with on a daily basis. Many animal species have impressive capabilities to navigate in complex or even harsh environments. Cataglyphis desert ants are a famous example. These ants use a remarkable navigational repertoire to find their way home after far-reaching foraging trips. How do naïve ants calibrate their visual navigational systems? The ants perform stereotyped sequences of learning walks before switching from tasks inside the darkness of their nest, to foraging under bright sunlight. Here, naïve ants align nest-directed views using the earth’s magnetic field as a compass reference. Neuronal plasticity was mapped in two visual pathways to higher brain centers during this transition. Both their first exposure to light, and the performance of learning walks lead to distinct changes in synaptic circuits along both visual pathways, reflecting calibration and memory formation in the ants’ visual compass systems.
Autoantibodies Against NMDA Receptors – Janus-Faced Molecules?
Authors: Wilke Justus B. H. , Ehrenreich Hannelore , Hollmann Michael 
Published: April 2019

Zusammenfassung
Wie schon der römische Gott des Anfangs und des Endes, Janus, könnten auch Antikörper (AB) gegen N-Methyl-D-aspartatrezeptoren (NMDAR) zwei Gesichter besitzen und duale Effekte vermitteln, wenn sie Zugang zum zentralen Nervensystem erhalten. In den letzten Jahren rückten Autoantikörper gegen die obligatorische NMDAR-Untereinheit GluN1 zunehmend in den Fokus von Ärzten, da GuN1-Antikörper (GluN1-AB) in der Cerebrospinalflüssigkeit als diagnostisches Kriterium für die sogenannte anti-NMDAR-Enzephalitis genutzt werden. Jedoch sind GluN1-AB auch im Blutserum vieler gesunder Menschen vorhanden. Mittlerweile haben zahlreiche Studien die Häufigkeit, die Epitope und den molekularen Wirkmechanismus von GluN1-AB verschiedener Ursprünge und Immunglobulinklassen analysiert. Interessanterweise vermitteln GluN1-AB die Quervernetzung und Internalisierung von NMDAR. In diesem Übersichtsartikel werden wir vorstellen, wie GluN1-AB Neurone potentiell vor den neurotoxischen Prozessen einer Übererregung der exzitatorischen Neurotransmission schützen, jedoch ebenfalls psychose-ähnliche Zustände auslösen können. Zusätzlich werden wir die Pathogenität von GluN1-AB mit Bezug auf entzündliche Prozesse genauer betrachten.

Authors: Yadav Vijay K. , Das S. 
Published: April 2019

Abstract
In this article, a scheme using active backstepping design method is proposed to achieve combination synchronization of n number of fractional order chaotic systems. In the proposed method the controllers are designed with the help of a new lemma and Lyapunov function in a systematic way. Synchronization among three/four fractional order systems have been shown as examples of synchronization of n-chaotic systems. Numerical simulation and graphical results clearly exhibit that the method of this new procedure is easy to implement and reliable for synchronization of fractional order chaotic systems.
Unsteady MHD Non-Newtonian Heat Transfer Nanofluids with Entropy Generation Analysis
Authors: Shukla Nisha , Rana Puneet , Bég O. Anwar 
Published: April 2019

AbstractA theoretical study of unsteady magnetohydrodynamic boundary layer stagnation point flow, heat and mass transfer of a second grade electrically-conducting nanofluid from a horizontal stretching sheet with thermal slip and second order slip velocity effects is presented. The Buongiorno formulation is employed for nanofluids and in addition the no-flux nanoparticle boundary condition is also considered. The appropriate similarity transformations are applied to convert the governing equations into the system of nonlinear partial differential equations, which is solved by using homotopy analysis method. Entropy generation and Bejan number have also been evaluated for the effects of magnetic parameter, Reynolds number and slip parameter in non-Newtonian (second-grade) time-dependent flow. The computations show that skin friction coefficient and entropy generation number increase with an increment in magnetic parameter whereas Bejan number decreases with it. Local Nusselt number decreases with an increase in the value of Eckert number (viscous dissipation) and thermal slip whereas the converse behaviour is captured for velocity parameter. The work is relevant to magnetohydrodynamic nanomaterials processing.
Mathematical Modelling of Hydromagnetic Casson non-Newtonian Nanofluid Convection Slip Flow from an Isothermal Sphere
Authors: Rao A. Subba , Sainath Seela , Rajendra P. , Ramu G. 
Published: April 2019

Abstract
In this article, the combined magnetohydrodynamic heat, momentum and mass (species) transfer in external boundary layer flow of Casson nanofluid from an isothermal sphere surface with convective condition under an applied magnetic field is studied theoretically. The effects of Brownian motion and thermophoresis are incorporated in the model in the presence of both heat and nanoparticle mass transfer convective conditions. The governing partial differential equations (PDEs) are transformed into highly nonlinear, coupled, multi-degree non-similar partial differential equations consisting of the momentum, energy and concentration equations via appropriate non-similarity transformations. These transformed conservation equations are solved subject to appropriate boundary conditions with a second order accurate finite difference method of the implicit type. The influences of the emerging parameters i.e. magnetic parameter (M), Buoyancy ratio parameter (N), Casson fluid parameter (β), Brownian motion parameter (Nb) and thermophoresis parameter (Nt), Lewis number (Le), Prandtl number (Pr) and thermal slip (ST) on velocity, temperature and nano-particle concentration distributions is illustrated graphically and interpreted at length.
Increasing viscoplastic (Casson) parameter decelerates the flow and also decreases thermal and nano-particle concentration. Increasing Brownian motion accelerates the flow and enhances temperatures whereas it reduces nanoparticle concentration boundary layer thickness. Increasing thermophoretic parameter increasing momentum (hydrodynamic) boundary layer thickness and nanoparticle boundary layer thickness whereas it reduces thermal boundary layer thickness. Increasing magnetohydrodynamic body force parameter decelerates the flow whereas it enhances temperature and nano-particle (species) concentrations. The study is relevant to enrobing processes for electric-conductive nano-materials, of potential use in aerospace and other industries.
La pobreza indígena en el discurso del Banco Mundial
Authors: Navarrete Saavedra Rodrigo Agustín 
Published: April 2019

El presente artículo pretende caracterizar el particular lugar y estatus que adquieren los pueblos indígenas en el discurso de la lucha contra la pobreza del Banco Mundial. A partir de un corpus de informes, directrices y declaraciones de dominio público, se caracteriza dicho discurso promovido por la agencia supraestatal a partir de los años setenta y ochenta del siglo xx y, posteriormente, la particular emergencia y visibilidad que adquieren los pueblos indígenas y la pobreza indígena en dicho entramado discursivo. El análisis y la discusión se concentra en tres vectores persistentes del discurso del Banco Mundial respecto de los pueblos indígenas: su condición rezagada y vulnerable frente al desarrollo, su naturalización y supeditación a las políticas de conservación medioambiental, y la necesidad de empoderarlos y hacerlos partícipes de los proyectos de desarrollo.

Published: April 2019

Electroluminescence (EL) is the most significant measure for light-emitting diodes since it probes the most relevant properties of the fully processed device during operation. In addition to the information gained by conventional spectrally resolved EL, scanning micro-EL provides spatially resolved information. The devices under investigation are InGaN/GaN-LEDs with single peak band-band emission at about 400 nm grown by MOVPE on sapphire substrates.The µ-EL-characterization is performed as a function of injection current densities and the emission is investigated from the epitaxial layer as well as from substrate side. Spatially resolved wavelength images reveal emission peaks between 406 nm and 417 nm, corresponding either to In fluctuations of 1 %−1.5 % or local fluctuations of piezo electric fields. Beside the information on the emission wavelength fluctuations µ-EL is used to determine the temperature distribution in the LEDs and to investigate transparent contacts.

Published: April 2019

AbstractFor the first time, p-type doping through beryllium implantation in gallium nitride was achieved by using a new annealing process, in which the sample was first annealed in forming gas (12% H2 and 88% N2), followed by annealing in pure nitrogen. Variable temperature Hall measurements showed that sheet hole concentrations of the annealed samples were about 1×1013 cm−2 with low hole mobilities. An ionization energy of 127 meV was estimated with a corresponding activation efficiency of ∼ 100%. SIMS results revealed a relationship between the enhanced diffusion of Be and activation of the acceptors.
Time-Resolved Spectroscopy of InGaN

Published: April 2019

We have used time-resolved photoluminescence (PL), with 400 nm (3.1 eV) excitation, to examine InxGa1−xN/GaN light-emitting diodes (LEDs) before the final stages of processing at room temperature. We have found dramatic differences in the time-resolved kinetics between dim, bright and super bright LED devices. The lifetime of the emission for dim LEDs is quite short, 110 ± 20 ps at photoluminescence (PL) maximum, and the kinetics are not dependent upon wavelength. This lifetime is short compared to bright and super bright LEDs, which we have examined under similar conditions. The kinetics of bright and super bright LEDs are clearly wavelength dependent, highly non-exponential, and are on the nanosecond time scale (lifetimes are in order of 1 ns for bright and 10 ns for super bright LED at the PL max). The non-exponential PL kinetics can be described by a stretched exponential function, indicating significant disorder in the material. Typical values for β, the stretching coefficient, are 0.45 − 0.6 for bright LEDs, at the PL maxima at room temperature. We attribute this disorder to indium alloy fluctuations.From analysis of the stretched exponential kinetics we estimate the potential fluctuations to be approximately 75 meV in the super bright LED. Assuming a hopping mechanism, the average distance between indium quantum dots in the super bright LED is estimated to be 20 Å.
A Resolution in the Spanish Banking Sector: The Case of Banco Popular Español
Authors: Kozińska Magdalena 
Published: April 2019

The restructuring of Banco Popular Español (BPE) through its takeover by Banco Santander provided a valuable example of the first resolution framework application, which allowed for the assessment of its effectiveness. However, similar crisis tools were also utilised in the Spanish banking sector in 2008–2013. Their analysis may provide a valuable contribution to the issue of selecting the most appropriate resolution tools for banks, which can be utilised by Spain and other EU countries when further restructuring their respective banking sectors or managing crises. The aim of this article is to evaluate the effectiveness of the BPE resolution. Additionally, other examples of the application of the “sale of business” tool from the Spanish banking crisis of 2008–2013 were assessed. The conclusions were then used to assess the possible application of similar tools at other banks in Spain and other European countries.
