Conformación de la agroindustria del amaranto en Santiago Tulyehualco, Xochimilco, México. Elementos que han permitido la transformación productiva y social en las familias rurales.

El presente trabajo versa sobre el desarrollo de la agroindustria del amaranto al sur del Distrito Federal, Ciudad de México. Esta actividad, además de ser de gran importancia económica para la localidad y comunidades vecinas, ya que en ella participan familias enteras, da un elevado sentido de pertenencia y cohesión entre los habitantes. La actividad agroindustrial consta de cuatro procesos: producción primaria, acopio, transformación y comercialización. Las familias amaranteras, que participan en este trabajo, participan en toda la cadena de valor desde hace varias generaciones. El eje de análisis se refiere a los factores que permiten la transformación en estructura y funcionamiento de la unidad de producción campesina hacia unidades agroindustriales. El enfoque que se utilizará para entender los procesos de cambio que se han dado en las unidades de producción rural y que permiten el desarrollo, evolución y consolidación de las estrategias se basa en el modelo de Organizaciones Productivas Familiares Rurales [1]. Dicho modelo separa tres ámbitos presentes e interrelacionados siempre presentes en las unidades: la propiedad, la familia y la actividad productiva agropecuaria. Este modelo nos ofrece argumentos de gran utilidad para entender los procesos de cambio que se gestan en las unidades campesinas, en su transito hacia la nueva cultura empresarial. Para la colección de información se recurrió a la aplicación de entrevistas, estructuradas, semi-estructuradas e historias de vida. Entre los principales hallazgos se puede mencionar: a) el nivel de desarrollo de la unidad de producción está relacionada con el momento en que se encuentre la familia dentro de su ciclo de desarrollo, b) las características personales del matrimonio propietario son determinantes para el cambio productivo implícito en el avance de la unidad y c) el entendimiento de las familias sobre sus necesidades, y la capacidad de gestión y negociación de sus representantes permiten el acceso a recursos que coadyuvan al cambio productivo. La principal conclusión es que el grado de avance de las unidades de producción, está en función del balance logrado por las familias operadoras entre intereses /necesidades y recursos /capacidades.Agroindustria, familia rural., Agribusiness, Agricultural and Food Policy, Community/Rural/Urban Development, Food Consumption/Nutrition/Food Safety, Labor and Human Capital,

Correlation Between Underground Radon Gas and Dormant Geological Faults

This work studies the concentration of radon in soil around a fault in the East Franklin Mountains in the El Paso area in West Texas. It is found that the in-soil production of radon is correlated to the existence of a fault even if it has not had any recorded activity in recent geological times. This adds to previous observations that link the production of radon to seismic activity, and seems to indicate that in non-active faults the radon production is due mainly to the radioactivity of the top soil and to the transport properties of the medium and not to deeper seismic activity. These results open the possibility of using in-soil radon gas concentrations as an examination tool of dormant faults

Programa de internacionalización de los productos de Finca La Isla

Dentro del proyecto 3J04 “Inteligencia Cultural y Comercial para los Negocios Internacionales”, se realizó el programa de internacionalización de varios productos naturales de la empresa “Finca La Isla”. Estos van desde: Miel, Jengibre, Vainilla, Cúrcuma, Canela, entre otros. El proyecto se centró en la exportación de la miel en dos destinos: Alemania y Turquía, centrándose en las ferias Internacionales de la Anuga 2023, en Colonia, y Apimondia 2022 en Estambul. El proyecto nos llevó a crear un brochure, en donde se pueden encontrar diferentes aspectos económicos, culturales, sociales, políticos, y de mercado, para que el empresario tenga en cuenta todo antes de iniciar la inversión. Nos dividimos en dos equipos de trabajo, cada uno enfocado en un país.ITESO, A.C

Nothing at Stake in Knowledge

In the remainder of this article, we will disarm an important motivation for epistemic contextualism and interest-relative invariantism. We will accomplish this by presenting a stringent test of whether there is a stakes effect on ordinary knowledge ascription. Having shown that, even on a stringent way of testing, stakes fail to impact ordinary knowledge ascription, we will conclude that we should take another look at classical invariantism. Here is how we will proceed. Section 1 lays out some limitations of previous research on stakes. Section 2 presents our study and concludes that there is little evidence for a substantial stakes effect. Section 3 responds to objections. The conclusion clears the way for classical invariantism

The Gettier Intuition from South America to Asia

This article examines whether people share the Gettier intuition (viz. that someone who has a true justified belief that p may nonetheless fail to know that p) in 24 sites, located in 23 countries (counting Hong Kong as a distinct country) and across 17 languages. We also consider the possible influence of gender and personality on this intuition with a very large sample size. Finally, we examine whether the Gettier intuition varies across people as a function of their disposition to engage in “reflective” thinking

International longitudinal registry of patients with atrial fibrillation and treated with rivaroxaban: RIVaroxaban Evaluation in Real life setting (RIVER)

Background Real-world data on non-vitamin K oral anticoagulants (NOACs) are essential in determining whether evidence from randomised controlled clinical trials translate into meaningful clinical benefits for patients in everyday practice. RIVER (RIVaroxaban Evaluation in Real life setting) is an ongoing international, prospective registry of patients with newly diagnosed non-valvular atrial fibrillation (NVAF) and at least one investigator-determined risk factor for stroke who received rivaroxaban as an initial treatment for the prevention of thromboembolic stroke. The aim of this paper is to describe the design of the RIVER registry and baseline characteristics of patients with newly diagnosed NVAF who received rivaroxaban as an initial treatment. Methods and results Between January 2014 and June 2017, RIVER investigators recruited 5072 patients at 309 centres in 17 countries. The aim was to enroll consecutive patients at sites where rivaroxaban was already routinely prescribed for stroke prevention. Each patient is being followed up prospectively for a minimum of 2-years. The registry will capture data on the rate and nature of all thromboembolic events (stroke / systemic embolism), bleeding complications, all-cause mortality and other major cardiovascular events as they occur. Data quality is assured through a combination of remote electronic monitoring and onsite monitoring (including source data verification in 10% of cases). Patients were mostly enrolled by cardiologists (n = 3776, 74.6%), by internal medicine specialists 14.2% (n = 718) and by primary care/general practice physicians 8.2% (n = 417). The mean (SD) age of the population was 69.5 (11.0) years, 44.3% were women. Mean (SD) CHADS2 score was 1.9 (1.2) and CHA2DS2-VASc scores was 3.2 (1.6). Almost all patients (98.5%) were prescribed with once daily dose of rivaroxaban, most commonly 20 mg (76.5%) and 15 mg (20.0%) as their initial treatment; 17.9% of patients received concomitant antiplatelet therapy. Most patients enrolled in RIVER met the recommended threshold for AC therapy (86.6% for 2012 ESC Guidelines, and 79.8% of patients according to 2016 ESC Guidelines). Conclusions The RIVER prospective registry will expand our knowledge of how rivaroxaban is prescribed in everyday practice and whether evidence from clinical trials can be translated to the broader cross-section of patients in the real world

Nuclear astrophysics with radioactive ions at FAIR

The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those processes, because they are shielded from the s-process flow and r-process, β-decay chains. These nuclei are attributed to the p and rp process. For all those processes, current research in nuclear astrophysics addresses the need for more precise reaction data involving radioactive isotopes. Depending on the particular reaction, direct or inverse kinematics, forward or time-reversed direction are investigated to determine or at least to constrain the desired reaction cross sections. The Facility for Antiproton and Ion Research (FAIR) will offer unique, unprecedented opportunities to investigate many of the important reactions. The high yield of radioactive isotopes, even far away from the valley of stability, allows the investigation of isotopes involved in processes as exotic as the r or rp processes

Search for a vector-like quark T′ → tH via the diphoton decay mode of the Higgs boson in proton-proton collisions at s \sqrt{s} = 13 TeV

A search for the electroweak production of a vector-like quark T′, decaying to a top quark and a Higgs boson is presented. The search is based on a sample of proton-proton collision events recorded at the LHC at = 13 TeV, corresponding to an integrated luminosity of 138 fb−1. This is the first T′ search that exploits the Higgs boson decay to a pair of photons. For narrow isospin singlet T′ states with masses up to 1.1 TeV, the excellent diphoton invariant mass resolution of 1–2% results in an increased sensitivity compared to previous searches based on the same production mechanism. The electroweak production of a T′ quark with mass up to 960 GeV is excluded at 95% confidence level, assuming a coupling strength κT = 0.25 and a relative decay width Γ/MT′ < 5%

Combined searches for the production of supersymmetric top quark partners in proton–proton collisions at √s=13Te

A combination of searches for top squark pair production using proton–proton collision data at a center-of-mass energy of 13TeV at the CERN LHC, corresponding to an integrated luminosity of 137fb$^{-1}$ collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on the model, the combined result excludes a top squark mass up to 1325GeV for a massless neutralino, and a neutralino mass up to 700GeV for a top squark mass of 1150GeV. Top squarks with masses from 145 to 295GeV, for neutralino masses from 0 to 100GeV, with a mass difference between the top squark and the neutralino in a window of 30GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420GeV
