"Valoración y exposición critica del derecho procesal del trabajo en Panamá"

El estudio se ha dividido en nueve (9) capítulos desglosados de la siguiente manera: El Capítulo N°1 habla sobre la configuración de las normas del trabajo. Las normas especializadas aparecen en el contexto nacional entrada la época republicana cuando se dictan las primeras normas que inciden en los temas procesales laborales. En 1914 se dicta una ley sobre la jornada máxima de trabajo asunto que le dio a Panamá el primer lugar en Latinoamérica en establecer la jornada de las 8 horas de trabajo. El Capítulo N° 2 expone el tema de la jurisdicción. La jurisdicción es una función que ejerce el Estado y que está dirigida a resolver los conflictos y litigios suscitados entre particulares o entre estos y el propio Estado de acuerdo con Derecho. Capítulo N° 3 expone el tema de la organización de la administración de trabajo. Nuestro sistema de administración laboral se concibió como un sistema intervencionista en el que el papel del Estado fija la dirección de las relaciones laborales relegando a un segundo plano si se quiere a las representaciones profesionales dicha faceta. El Capítulo N° 4 expone el tema de los principios del Derecho procesal del trabajo. La importancia de la cabal compresión de los principios informadores del proceso laboral cobra especial significancia para quienes en primer lugar deben administrar justicia laboral pues de ellos dependerá la solución ajustada a los fines y naturaleza del Derecho del trabajo. El Capítulo N° 5 se encarga de analizar los procesos laborales. Bajo este epígrafe examinaremos los distintos procesos que se desarrollan en la legislación laboral panameña. El Capítulo N° 6 examina las modalidades procesales especiales. Existe discusión en la doctrina acerca de la denominación a utilizar para los procesos que revisaremos en este capítulo. Para unos se trata de procesos especiales de trabajo y para otros estamos frente a modalidades procesales nada más. El Capítulo N° 7 se encarga de analizar lo relativo a la prueba en el proceso laboral. Bajo este capítulo examinaremos los aspectos más relevantes relacionados a la prueba en el proceso laboral y el Derecho del trabajo en general. El Capítulo N° 8 se encarga del estudio de los medios excepcionales de terminación del proceso. En el presente capítulo se estudiará la finalización del proceso cuando la misma es producida antes de su etapa final que es la sentencia en firme. En el Capítulo N° 9 se examinan los distintos recursos laborales. Bajo este tema revisaremos los mecanismos establecidos en la ley laboral para revisar las decisiones judiciales dictadas por los jueces y magistrados

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

A community-derived classification for extant lycophytes and ferns

Phylogeny has long informed pteridophyte classification. As our ability to infer evolutionary trees has improved, classifications aimed at recognizing natural groups have become increasingly predictive and stable. Here, we provide a modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community-based approach. We use monophyly as the primary criterion for the recognition of taxa, but also aim to preserve existing taxa and circumscriptions that are both widely accepted and consistent with our understanding of pteridophyte phylogeny. In total, this classification treats an estimated 11 916 species in 337 genera, 51 families, 14 orders, and two classes. This classification is not intended as the final word on lycophyte and fern taxonomy, but rather a summary statement of current hypotheses, derived from the best available data and shaped by those most familiar with the plants in question. We hope that it will serve as a resource for those wanting references to the recent literature on pteridophyte phylogeny and classification, a framework for guiding future investigations, and a stimulus to further discourse

Heavy flavour decay muon production at forward rapidity in proton–proton collisions at √s=7 TeV

The production of muons from heavy flavour decays is measured at forward rapidity in proton–proton collisions at √s=7 TeV collected with the ALICE experiment at the LHC. The analysis is carried out on a data sample corresponding to an integrated luminosity Lint=16.5 nb−1. The transverse momentum and rapidity differential production cross sections of muons from heavy flavour decays are measured in the rapidity range 2.5<y<4, over the transverse momentum range 2<pt<12 GeV/c. The results are compared to predictions based on perturbative QCD calculations

Neutral pion and η meson production in proton–proton collisions at √s=0.9 TeV and s=√7 TeV

he first measurements of the invariant differential cross sections of inclusive π0 and η meson production at mid-rapidity in proton–proton collisions at s=0.9 TeV and s=7 TeV are reported. The π0 measurement covers the ranges 0.4<pT<7 GeV/c and 0.3<pT<25 GeV/c for these two energies, respectively. The production of η mesons was measured at s=√7 TeV in the range 0.4<pT<15 GeV/c. Next-to-Leading Order perturbative QCD calculations, which are consistent with the π0 spectrum at s=0.9 TeV, overestimate those of π0 and η mesons at s=√7 TeV, but agree with the measured η/π0 ratio at s=√7 TeV

Multi-strange baryon production in pp collisions at √s=7 TeV with ALICE

A measurement of the multi-strange Ξ− and Ω− baryons and their antiparticles by the ALICE experiment at the CERN Large Hadron Collider (LHC) is presented for inelastic proton–proton collisions at a centre-of-mass energy of 7 TeV. The transverse momentum (pT) distributions were studied at mid-rapidity (|y|6.0 GeV/c. We also illustrate the difference between the experimental data and model by comparing the corresponding ratios of (Ω−+Ω¯+)/(Ξ−+Ξ¯+) as a function of transverse mass

Coherent J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at √sNN=2.76 TeV

The ALICE Collaboration has made the first measurement at the LHC of J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at sNN=2.76 TeV. The J/ψ is identified via its dimuon decay in the forward rapidity region with the muon spectrometer for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 55 μb−1. The cross section for coherent J/ψ production in the rapidity interval −3.6<y<−2.6 is measured to be dσJ/ψcoh/dy=1.00±0.18(stat)−0.26+0.24(syst) mb. The result is compared to theoretical models for coherent J/ψ production and found to be in good agreement with those models which include nuclear gluon shadowing
