The Relationship

Considerable research has examined the relationship between positive emotion and cognitive flexibility. Less is known, however, about the causal relationship between discrete positive emotions, specifically gratitude, and cognitive flexibility. Given that different positive emotions may dissimilarly affect cognitive functioning, we sought to examine the effect of state gratitude on cognitive flexibility. A pilot study with ninety-five participants was employed to ensure the effectiveness of our gratitude manipulation. One hundred and thirteen participants were recruited for the main study, which utilized a within-subject experimental approach. After the manipulation, participants completed a well-established task-switching paradigm, which was used to measure cognitive flexibility. Contrary to our hypotheses, we did not find any evidence that state gratitude may enhance cognitive flexibility. The current study identified some boundary conditions around the potential benefits of the experience of gratitude.

Abstract This study aims at exploring the phenomenon of psychological transportation in translation from an experimental approach. Firstly, we investigate whether the emotions depicted in source texts may influence the level of transportation experienced by translators. Secondly, we try to determine whether different levels of transportation in the texts can make a difference in terms of translation performance. Based on previous work about narrative transportation in products of fiction, as well as the phenomenon known as the “paradox of pleasurable sadness”, we depart from the hypothesis that sad texts lead to a higher degree of psychological transportation than happy texts (H1). Taking into account previous theories and empirical results about the benefits of visualization and emotional engagement in translation, we also predict that highly-transported participants will render higher-quality (H2) and more creative translations (H3) than low-transported participants. For this purpose, a pilot study was conducted consisting of two literary translation tasks with opposing-valence texts (happy vs. sad). Lack of statistically significant differences for our hypothesis suggests that some adjustments in the methodology would be needed to achieve conclusive results; however, we believe that further research on the impact of transportation in translation quality and creativity is still worthwhile.

In this pilot study, we assessed the reliability of cognitive testing for kids and adolescents ages 8-19 years of age with narcolepsy or subjective daytime sleepiness compared to healthy controls. Forty-six participants took part in the study (n=18 with narcolepsy type 1, n=6 with subjective daytime sleepiness, and n= 22 healthy controls recruited from the community). Participants completed verbal (vocabulary testing) and non-verbal intelligence quotient (IQ) tasks (block design, matrix reasoning) from the Weschler Abbreviated Scale of Intelligence- Second Edition (WASI-II) in-person or remotely in their home through a HIPAA compliant telehealth web platform with conditions counterbalanced. We found that vocabulary T-scores showed good reliability with intraclass correlation coefficient (ICC) of 0.76 (95% CI: 0.64, 0.85) between remote and in-person testing conditions. Matrix Reasoning T-scores showed moderate reliability ( ICC 0.69, 95% CI: 0.68, 0.90) and Block Design T-scores was poor between testing conditions. Bland-Altman plots showed outliers on vocabulary and matrix reasoning tasks performed better on remote assessments. Overall, the results of this pilot study support the feasibility and reliability of verbal and non-verbal IQ scores collected by telehealth. Use of telehealth to collect verbal and non-verbal IQ scores may offer a means to acquire cognitive data for pediatric sleep research through the COVID-19 pandemic and beyond.

Various classifications of generations associated with historical and physical time are considered. It is shown that the culturological connection of modern Russian generations has a cyclical nature and can be investigated both at the macrolevel from the standpoint of economic sociology, and at the microlevel from the standpoint of economic psychology. The idea is substantiated that the sociodesign of the generation continuity is associated with mental attitudes and life-meaning values that are accepted and shared by different generations. In the pilot study, students and their parents' meaningful values have been determined. Based on the analysis of a number of studies, some trends in forming the values of generation Z and recommendations for teaching generation Z in modern cultural and historical conditions have been identified.

Experimental Methodology

The tricuspid valve (TV) is composed of three leaflets that coapt during systole to prevent deoxygenated blood from re-entering the right atrium. The connection between the TV leaflets’ microstructure and the tissue-level mechanical responses has yet to be fully understood in the TV biomechanics society. This pilot study sought to examine the load-dependent collagen fiber architecture of the three TV leaflets, by employing a multiscale, combined experimental approach that utilizes tissue-level biaxial mechanical characterizations, micro-level collagen fiber quantification, and histological analysis. Our results showed that the three TV leaflets displayed greater extensibility in the tissues’ radial direction than in the circumferential direction, consistently under different applied biaxial tensions. Additionally, collagen fibers reoriented towards the direction of the larger applied load, with the largest changes in the alignment of the collagen fibers under radially-dominant loading. Moreover, collagen fibers in the belly region of the TV leaflets were found to experience greater reorientations compared to the tissue region closer to the TV annulus. Furthermore, histological examinations of the TV leaflets displayed significant regional variation in constituent mass fraction, highlighting the heterogeneous collagen microstructure. The combined experimental approach presented in this work enables the connection of tissue mechanics, collagen fiber microstructure, and morphology for the TV leaflets. This experimental methodology also provides a new research platform for future developments, such as multiscale models for the TVs, and the design of bioprosthetic heart valves that could better mimic the mechanical, microstructural, and morphological characteristics of the native tricuspid valve leaflets.

<p>The global water storage capacity of hydroelectric reservoirs is decreasing annually while the economic activity, the hydropower industry and the world population continue to grow strongly. The boom in hydropower development in Andean river basins was identified as one of the top 15 global conservation issues. For this region, the electricity generation might increase by 550% from 2005 to the year 2050, thereby needing an increase in water volume from 70.5 billion m3 to 150.7 billion m³. Of the Andean countries, Peru has the highest numbers of existing and proposed hydropower projects, because of its rapidly evolving energy demands (estimated at 8% growth per year) and regulatory framework that aims at promoting renewable energy. Despite initial efforts, studies that describe the impact of changing sediment transfer due to climate change to the hydroelectric infrastructural system are still limited.</p><p>This paper evaluates the potential impact of climate variability on the water storage capacity of hydroelectric reservoirs in Andean countries, via a case study of the Cañete River in the Peruvian Coastal Range. It houses the 220 MW El Platanal hydroelectric plant and the Capillucas reservoir that provide the surrounding areas with water and energy. We used a hydrological model (HEC-HMS) coupled with a sediment transport model (HEC-RAS) to simulate future changes in river discharge and sediment load. Ten scenarios were developed, a combination of two different precipitation patterns and five different precipitation rates.</p><p>The average sediment load of the Cañete River was estimated at 981 kTon/yr upstream of the Capillucas reservoir, which is in agreement with published erosion rates for the area. Our results show that the lifespan of the Capillucas reservoir ranges from 7 years for the most pessimistic scenario to 31 years for the most optimistic scenario. This is much shorter than the projected lifespan of 50 years. This pilot study illustrates the vulnerability of Andean hydroelectric reservoirs against future climate change.</p>

Resolution Level

The use of thick specimens (0.5 μm to 5.0 μm or more) is one of the most resourceful applications of high-voltage electron microscopy in biological research. However, the energy loss experienced by the electron beam in the specimen results in chromatic aberration and thus in a deterioration of the effective resolving power. This sets a limit to the maximum usable specimen thickness when investigating structures requiring a certain resolution level.An experimental approach is here described in which the deterioration of the resolving power as a function of specimen thickness is determined. In a manner similar to the Rayleigh criterion in which two image points are considered resolved at the resolution limit when their profiles overlap such that the minimum of one coincides with the maximum of the other, the resolution attainable in thick sections can be measured by the distance from minimum to maximum (or, equivalently, from 10% to 90% maximum) of the broadened profile of a well-defined step-like object placed on the specimen.
