Does time constrain affect consumer intention to purchase? A case study with orange/pomegranate juice.

The influence of time pressure on consumer perception may be particularly relevant for the design of food packages. The aim of the present work was to evaluate the influence of time-constraint on results from a rating-based conjoint task, using pomegranate/orange juice as case study. One hundred consumers evaluated the intention to purchase of images of juice bottles, which were designed by manipulating the following variables: bottle design, front-of-pack nutritional information, nutrition claim and processing claim. They were randomly divided into two experimental conditions: control and time-constraint. Consumers with a time-constraint gave significantly higher intention to purchase scores than those in control condition, but time-constraint did not largely modify the way in which consumers evaluated their intention to purchase. In both experimental conditions consumers gave higher intention to purchase scores for bottles with traditional design, which included processing claim and front-of-pack nutritional information. Result suggests that graphic design could help consumers to make healthier food choices.Food: the tree that sustains life. 1648

Morphological Study of Granular-Granular Impact Craters through Time-of-Flight Cameras: from Concept to Automation in Python

Laboratory made granular-granular impact craters have been used as model analogues of planetary impact craters. These kind of craters have been observed and studied using profilometry techniques that allow to retrieve important morphologic features from the impacted surface. In this work, we propose to use a Time-of-Flight camera (Microsoft Kinect One) for the acquisition of depth data. We show comparisons between the typically used technique and the analysis derived from the Time-of-Flight data. We also release craterslab, a Python library developed to automate most of the tasks from the process of studying impact craters produced by granular projectiles hitting on the surface of granular targets. The library is able to acquire, identify, and measure morphological features of impacted surfaces through the reconstruction of 3D topographic maps. Our results show that using a Time-of-Flight camera and automating the data processing with a software library for the systematic study of impact craters can produce very accurate results while reducing the time spent on different stages of the process

Influencia de la inteligencia emocional en la autoeficacia para el liderazgo

Muchas investigaciones se han centrado en analizar y estudiar los beneficios que la inteligencia emocional podría aportar en temas de capacitación y desarrollo de personal. El objetivo de este estudio es comparar las relaciones que existen entre la inteligencia emocional rasgo de los líderes con algunos procesos emocionales; y cómo éstos procesos influyen en otras variables como la autoeficacia para el liderazgo y el desempeño. La muestra fue de 176 estudiantes de Psicología. Cada uno de ellos fue asignado aleatoriamente a los roles de líder y de seguidor, y fueron distribuidos para conformar equipos. El procedimiento de la investigación se desarrolló a lo largo de tres fases. Los resultados del estudio mostraron que la inteligencia emocional rasgo de los líderes influyó significativamente en la autoeficacia para el liderazgo y también predijo el desempeño final del equipo, aunque en este último caso su influencia es parcial. Esta investigación tiene importantes repercusiones para avanzar en la comprensión de las emociones en el lugar de trabajo.Many researches have focused on analyzing and studying the benefits of emotional intelligence could provide in training and staff development issues. The aim of this study is to compare the relationship between trait emotional intelligence of leaders with some emotional processes and how these processes affect other variables such as leadership self-efficacy, self-efficacy and collective effectiveness of a team. The sample comprised 176 students of Psychology. Each person was randomly assigned the roles of leader and follower and they were distributed to form teams. The research procedure was developed over three phases. The results showed that self-efficacy for leadership significantly influenced self-efficacy in the task of the leader and also predicted the team’s final performance; although in the latter case its influence is only partial. This research has important implications for advancing the understanding of emotions in the workplace

Estudio comparativo de medición entre lecturas visuales y espectrofotométricas en pruebas de susceptibilidad in vitrode aislamientos de candida

Se realizó un estudio de susceptibilidad in vitrofrente a itraconazol, ketoconazol y clotrimazol de 144 cepas de Candida, conservadas y previamente identificadas, aisladas de la cavidad oral de pacientes infectados por elvirus de inmunodeficiencia humana (VIH) con cuadros clínicos de candidiasis orofaríngea (COF). El estudio se llevó a cabo mediante dos metodologías; la primera, utilizando los requerimientos del Clinical and Laboratory Standard Institute (CLSI), en el cual está establecida la lectura visual para determinar los patrones de susceptibilidad; y la segunda, mediante la propuesta de la European Committee on Antibiotic Susceptibility Testing, el cual tiene fijado la lectura espectrofotométrica para eliminar las posibles subjetividades de la metodología del CLSI. Los resultados obtenidos mediante ambas lecturas no mostraron diferencias mayores a dos diluciones en los valores de concentración mínima inhibitoria, y demostraron que ambos métodos se correlacionan y es importante para aquellos laboratorios de pocos recursos económicos.Palabras clave: Susceptibilidad in vitr,; Candida, lectura visual, CLSI, lectura espectrofotométrica, EUCAST azoles, VIH/sida.</p

High-resolution variability of dissolved and suspended organic matter in the Cape Verde Frontal Zone

21 pages, 8 figures, 4 tables.-- This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY)Distributions of dissolved (DOM) and suspended (POM) organic matter, and their chromophoric (CDOM) and fluorescent (FDOM) fractions, are investigated at high resolution (< 10 km) in the Cape Verde Frontal Zone (CVFZ) during fall 2017. In the epipelagic layer (< 200 m), meso- and submesoscale structures (meanders, eddies) captured by the high resolution sampling dictate the tight coupling between physical and biogeochemical parameters at the front. Remarkably, fluorescent humic-like substances show relatively high fluorescence intensities between 50 and 150 m, apparently not related to local mineralization processes. We hypothesize that it is due to the input of Sahara dust, which transports highly re-worked DOM with distinctive optical properties. In the mesopelagic layer (200-1500 m), our results suggest that DOM and POM mineralization occurs mainly during the transit of the water masses from the formation sites to the CVFZ. Therefore, most of the local mineralization seems to be due to fast-sinking POM produced in situ or imported from the Mauritanian upwelling. These local mineralization processes lead to the production of refractory CDOM, an empirical evidence of the microbial carbon pump mechanism. DOM released from these fast-sinking POM is the likely reason behind the observed columns of relatively high DOC surrounded by areas of lower concentration. DOM and POM dynamics in the CVFZ has turned out to be very complex, in parallel to the complexity of meso- and submesoscale structures present in the area. On top of this high resolution variability, the input of Sahara dust or the release of DOM from sinking particles have been hypothesized to explain the observed distributionsThis work was funded by Spanish National Science Plan research grants FERMIO (CTM2014–57334–JIN) and FLUXES (CTM2015-69392-C3), co–financed with FEDER funds, and e-IMPACT (PID2019-109084RB-C21 and –C22).

Leukocyte Tyrosine Kinase Functions in Pigment Cell Development

A fundamental problem in developmental biology concerns how multipotent precursors choose specific fates. Neural crest cells (NCCs) are multipotent, yet the mechanisms driving specific fate choices remain incompletely understood. Sox10 is required for specification of neural cells and melanocytes from NCCs. Like sox10 mutants, zebrafish shady mutants lack iridophores; we have proposed that sox10 and shady are required for iridophore specification from NCCs. We show using diverse approaches that shady encodes zebrafish leukocyte tyrosine kinase (Ltk). Cell transplantation studies show that Ltk acts cell-autonomously within the iridophore lineage. Consistent with this, ltk is expressed in a subset of NCCs, before becoming restricted to the iridophore lineage. Marker analysis reveals a primary defect in iridophore specification in ltk mutants. We saw no evidence for a fate-shift of neural crest cells into other pigment cell fates and some NCCs were subsequently lost by apoptosis. These features are also characteristic of the neural crest cell phenotype in sox10 mutants, leading us to examine iridophores in sox10 mutants. As expected, sox10 mutants largely lacked iridophore markers at late stages. In addition, sox10 mutants unexpectedly showed more ltk-expressing cells than wild-type siblings. These cells remained in a premigratory position and expressed sox10 but not the earliest neural crest markers and may represent multipotent, but partially-restricted, progenitors. In summary, we have discovered a novel signalling pathway in NCC development and demonstrate fate specification of iridophores as the first identified role for Ltk
