    La literatura ha considerado al contrato psicológico como uno de los ejes que condicionan las relaciones que se dan en el entorno laboral. El cumplimiento de las expectativas son el punto de referencia. Desde un punto de vista racional, debido a la toma de decisiones basadas en un sentido de equidad y de equilibrio, el cumplimiento o no del contrato psicológico, conlleva a una serie de reajustes en el comportamiento de las partes. Estas decisiones se consideran de tipo estratégico, esto es, las decisiones de una parte afectan a las decisiones que tome la otra parte. El objetivo de este trabajo es poner luz al comportamiento organizacional en relación al contrato psicológico, analizándolo desde una perspectiva racional. Este trabajo, a través de un contraste teórico, analiza el comportamiento de las partes en un conflicto derivado del incumplimiento del contrato psicológico, con las fases del Juego de Seguridad de la Teoría de Juegos, evidenciándose un paralelismo que podría derivarse en una nueva forma de abordar la investigación de los contratos psicológicos. Las implicaciones de este trabajo estriban en servir de pilares de apoyo para futuras investigaciones de tipo empírico, que arrojen luz sobre la posibilidad de abordar los conflictos derivados del contrato psicológico, desde una perspectiva racional y, por otra parte, la implicación práctica de este trabajo está relacionada con la ayuda que puede proporcionar en la toma de decisiones en el ámbito de la gestión de los RRHH, para analizar las posibles consecuencias y soluciones al conflicto relacionado con el incumplimiento del contrato psicológico

    Teletrabajo. ¬Ņse cumplen las expectativas organizativas de la empresa y la mejora del balance de vida laboral y familiar del trabajador?

    El teletrabajo ha ido generado altas expectativas para consolidarse como una de las opciones más atractivas en políticas de flexibilización laboral. En 2020, tras la irrupción de la COVID-19, debido al confinamiento forzoso, instituciones y organizaciones empresariales, al objeto de desarrollar su normal actividad se ven obligadas a implementar el teletrabajo entre sus empleados. A partir de este hecho, no solo ha crecido el uso del teletrabajo, sino que las investigaciones con respecto al mismo han aumentado de forma extraordinaria. El objetivo de este trabajo es ampliar conocimiento en cuanto a los efectos que el teletrabajo tiene sobre las organizaciones empresariales, las familias y en el propio trabajador. Para ello, se lleva a cabo una revisión sistemática de la literatura sobre una muestra de 78 publicaciones de la base de datos de Web of Sciense. Los resultados sugieren que, si bien, por definición el teletrabajo aportaría mejoras en la conciliación laboral y familiar, no existe consenso. Entre los principales condicionantes se encuentran; la dificultad de llevar una gestión adecuada de los límites y del uso del tiempo, por parte del teletrabajador, y las interferencias del trabajo en el entorno familiar y viceversa. Las principales consecuencias; para la organización, aspectos organizativos y de rendimiento, para la vida familiar, la invasión del entorno laboral en el hogar y, para el trabajador, el impacto generado por el choque de roles laborales y familiares, y un mayor aislamiento físico y psicológico. Esta investigación tiene implicaciones prácticas que pueden ayudar a los gestores de RRHH y como base de futuras investigaciones sobre teletrabajo.Universidad de Málaga.

    Differences in ex-vivo Chemosensitivity to Anthracyclines in First Line Acute Myeloid Leukemia

    Induction schedules in acute myeloid leukemia (AML) are based on combinations of cytarabine and anthracyclines. The choice of the anthracycline employed has been widely studied in multiple clinical trials showing similar complete remission rates. Using an ex vivo test we have analyzed if a subset of AML patients may respond differently to cytarabine combined with idarubicin, daunorubicin or mitoxantrone. Bone marrow (BM) samples of 198 AML patients were incubated for 48 hours in 96 well plates, each well containing different drugs or drug combinations at different concentrations. Ex vivo drug sensitivity analysis was made using the PharmaFlow platform maintaining the BM microenvironment. Drug response was evaluated as depletion of AML blast cells in each well after incubation. Annexin V-FITC was used to quantify the ability of the drugs to induce apoptosis, and pharmacological responses were calculated using pharmacokinetic population models. Similar dose-respond graphs were generated for the three anthracyclines, with a slight decrease in EC with idarubicin (p=1.462E-06), whereas the interpatient variability of either drug was large. To identify those cases of selective sensitivity to anthracyclines, potency was compared, in terms of area under the curve. Differences in anthracycline monotherapy potency greater than 30% from 3 pairwise comparisons were identified in 28.3% of samples. Furthermore, different sensitivity was detected in 8.2% of patients comparing combinations of cytarabine and anthracyclines. A third of the patients could benefit from the use of this test in the first line induction therapy selection, although it should be confirmed in a clinical trial specifically designed

    Database of spatial distribution of non indigenous species in Spanish marine waters

    Research in marine Spanish waters are focused on several actions to achieve an effectively management on protected areas, with the active participation of the stakeholders and research as basic tools for decision-making. Among these actions, there is one about the knowledge and control on NIS. One of its objectives is the creation of NIS factsheets, which are going to be added to the National Marine Biodiversity Geographical System (GIS) providing complementary information about taxonomic classification, common names, taxonomic synonyms, species illustrations, identification morphological characters, habitat in the native and introduced regions, biological and ecological traits, GenBank DNA sequences, world distribution, first record and evolution in the introduced areas, likely pathways of introduction, effects in the habitats and interaction with native species, and potential management measures to apply. The database will also provide data for (1) the European online platforms, (2) the environmental assessment for the Descriptor 2 (D2-NIS) of the EU Marine Strategy Framework Directive (MSFD), as well as (3) supporting decisions made by stakeholders. It is the result of extensive collaboration among scientist, manager’s and citizen science in the Spanish North-Atlantic, South-Atlantic, Gibraltar Strait-Alboran, Levantine-Balearic and Canary Islands marine divisions, providing an updated overview of the spatial distribution of relevant extended and invasive NIS of recent and established NIS introduced by maritime transport and aquaculture pathways, as well as on cryptogenic or native species in expansion due to the climatic water warming trend

    Publisher Copyright: ¬© 2020 The Author(s). Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods: In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence of hyperoxemia (PaO2 > 100 mmHg) on day 1, sustained (i.e., present on day 1 and day 2) hyperoxemia, or excessive oxygen use (FIO2 ‚Č• 0.60 during hyperoxemia). Results: Of 2005 patients that met the inclusion criteria, 131 (6.5%) were hypoxemic (PaO2 < 55 mmHg), 607 (30%) had hyperoxemia on day 1, and 250 (12%) had sustained hyperoxemia. Excess FIO2 use occurred in 400 (66%) out of 607 patients with hyperoxemia. Excess FIO2 use decreased from day 1 to day 2 of ARDS, with most hyperoxemic patients on day 2 receiving relatively low FIO2. Multivariate analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FIO2 use and adverse clinical outcomes. Mortality was 42% in patients with excess FIO2 use, compared to 39% in a propensity-matched sample of normoxemic (PaO2 55-100 mmHg) patients (P = 0.47). Conclusions: Hyperoxemia and excess oxygen use are both prevalent in early ARDS but are most often non-sustained. No relationship was found between hyperoxemia or excessive oxygen use and patient outcome in this cohort.
