El derecho al trabajo digno ante el ODS 8 y la tecnificación del mercado de trabajo mexicano

El incremento del desarrollo y uso de tecnologías a nivel nacional e internacional en un mundo globalizado han contribuido a que el trabajo se transforme al surgir nuevas formas y contextos para realizarlo, representando retos para garantizar el derecho humano al trabajo mientras se asegura que este sea decente. A partir de ello, se analizó el vínculo entre trabajo decente y el Objetivo de Desarrollo Sostenible número 8 de la Agenda 2030 considerando la tecnificación del mercado de trabajo y en particular del caso mexicano desde el enfoque cualitativo con un estudio socio-jurídico descriptivo. Se identificaron características de la tecnificación del mercado de trabajo, del derecho al trabajo decente y su relación con otros derechos humanos. Concluyendo que los esfuerzos realizados deben reforzarse con la participación de actores sociales claves como sociedad, gobierno, academia e iniciativa privada que en suma permitan cumplir con las metas planteadas y garantizar derechos humanos

Desarrollo de una aplicación móvil multi plataforma que utilice asistente virtual inteligente para apoyar el servicio al cliente en supermercados: caso de estudio Mercasur 401 en Bogotá

En este trabajo de investigación se presenta un sistema de atención al cliente para supermercados, específicamente en el supermercado Merca Sur 401 ubicado en Bogotá, utilizando IA y aplicaciones multiplataforma que busca compensar las dificultades de comunicación con el cliente. En la actualidad con el surgimiento de nuevos establecimientos dedicados a la venta de víveres y el surgimiento de aplicaciones que ofrecen servicios de venta de víveres de manera online, la manera en que se aborda al cliente es muy importante, esto conlleva a que las empresas deben buscar diferentes alternativas para poseer un valor adicional a los servicios que están ofreciendo actualmente. Por esto, el sistema propuesto en este proyecto de grado pretende ayudar a disminuir los tiempos de respuesta en el supermercado, minimizar las pérdidas de ventas que se generan por mal manejo al cliente y adicionar un servicio tecnológico a los establecimientos que les ayude a dar un mejor manejo y tener un valor agregado con respecto a los dos nuevos modelos de negocios que se están desarrollado.In this work of investigation presents a system of attention to the client for supermarkets, specifically in the supermarket “Merca Sur 401” in Bogota, using IA and applications cross platform that looks for to compensate the difficulties of communication with the client.

Imaging of Tendons

Magnetic resonance imaging (MRI) and ultrasound (US) are useful radiologic modalities that allow adequate evaluation of tendon anatomy and integrity. Each modality contains unique advantages as diagnostic tools, allowing detection of tendon injuries and pathology. This chapter focuses on the key imaging features of tendons in both ultrasound and magnetic resonance, with emphasis on the major joints such as the shoulder, elbow, hand/wrist, hip, knee and foot/ankle joints. Each section provides a review of standard magnetic resonance imaging protocols and ultrasound technique, along with a discussion of the radiologic appearance of the most common tendon pathology affecting each joint

A BODIPY-Based Fluorescent Sensor for Amino Acids Bearing Thiol

Herein, we describe the synthetic route to access a red-emitting BODIPY from its α-diformylated precursor. The photophysical signatures of this dye are sensitive to the presence of thiol-containing amino acids (like cysteine, homocysteine, and glutathione) in the surrounding environment. This sensor provides up to three detection channels to monitor and quantify these biomolecules, even at low concentrations (down to micromolar). Moreover, owing to the pronounced splitting of the spectral band profile induced by these amino acids, the detection can be visualized following just the evolution of the fluorescence color by the naked eye

Knowledge to Serve the City: Insights from an Emerging Knowledge-Action Network to Address Vulnerability and Sustainability in San Juan, Puerto Rico

This paper presents initial efforts to establish the San Juan Urban Long-Term Research Area Exploratory (ULTRA-Ex), a long-term program aimed at developing transdisciplinary social-ecological system (SES) research to address vulnerability and sustainability for the municipality of San Juan. Transdisciplinary approaches involve the collaborations between researchers, stakeholders, and citizens to produce socially-relevant knowledge and support decision-making. We characterize the transdisciplinary arrangement emerging in San Juan ULTRA-Ex as a knowledge-action network composed of multiple formal and informal actors (e.g., scientists, policymakers, civic organizations and other stakeholders) where knowledge, ideas, and strategies for sustainability are being produced, evaluated, and validated. We describe in this paper the on-the-ground social practices and dynamics that emerged from developing a knowledge-action network in our local context. Specifically, we present six social practices that were crucial to the development of our knowledge-action network: 1) understanding local framings; 2) analyzing existing knowledge-action systems in the city; 3) framing the social-ecological research agenda; 4) collaborative knowledge production and integration; 5) boundary objects and practices; and 6) synthesis, application, and adaptation. We discuss key challenges and ways to move forward in building knowledge-action networks for sustainability. Our hope is that the insights learned from this process will stimulate broader discussions on how to develop knowledge for urban sustainability, especially in tropical cities where these issues are under-explored

La prevalencia de la obesidad a nivel mundial se ha incrementadorápidamente durante los últimos años debido principalmentea los cambios en el estilo de vida de la poblacióncon un aumento significativo en el consumo de energía y disminuciónde los niveles de actividad física. Es por esto quela comunidad científica está interesada en comprender deforma más profunda los mecanismos que regulan la fisiopatologíade la obesidad. Dentro de los diferentes blancos deestudio se encuentra la adipogénesis, cuyo entendimiento esfundamental para comprender el desarrollo de la obesidad ylas patologías asociadas a esta. Recientemente ha surgidoimportantes evidencias que involucran a la proteína de canalesde “Gap Junction” conexina 43 (Cx43) en la regulaciónde los procesos relacionados con adipogénesis, cuyo papeles básicamente anti-adipogénico, sin embargo, nuevas funcionesde Cx43 en la regulación de la formación del tejidoadiposo siguen descubriéndose

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper. DR14 happened on 31st July 2017. 19 pages, 5 figures. Accepted by ApJS on 28th Nov 2017 (this is the "post-print" and "post-proofs" version; minor corrections only from v1, and most of errors found in proofs corrected

Trabajo y vida indígenas en los trapiches del Nuevo Reino de Granada, 1576 – 16741

ABSTRACT: By a Crown´s rule, native workforce was forbidden inside the trapiches and sugar mills. Nonetheless, some Crown´s employees of the New Kingdom of Granada, in particular chief magistrates, avoided exerting this prohibition drastically, and allowed many indigenous people of encomiendas to pay their tributes with their labor on sugar production. This article studies both the reasons of this permissiveness and the changes that working on the trapiches generated among natives, especially those aspects linked to their community life and their consumption habits.RESUMEN: La mano de obra indígena estaba prohibida dentro de los trapiches e ingenios de azúcar por mandato de la Corona española. Sin embargo, en el Nuevo Reino de Granada los oficiales reales, especialmente los corregidores, evitaron ejercer drásticamente esta prohibición y permitieron que muchos indios de encomienda pagaran su tributación con el trabajo azucarero. En este artículo se estudian las razones de esta permisividad, así como los cambios que generó entre los indígenas trabajar en los trapiches, especialmente los aspectos vinculados a la vida comunitaria y a los hábitos de consumo de los indígenas

Sloan Digital Sky Survey IV: mapping the Milky Way, nearby galaxies, and the distant universe

We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median ). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July
