Sport Coaches Burnout as a Threat to Professional Success, Mental Health and Well-Being
2021
The article explores motivational and personality predictors of burnout syndrome in sports coaches. The study involved 183 sports coaches of 20–63 years old (86.9% women; M=41.34±10.56 years), with professional experience for 13.83±9.98 years. Three components of professional burnout ― Emotional exhaustion, Depersonification and Reduction of professional achievements ― were measured with the adapted Maslach professional burnout inventory (Vodopyanova, et al 2008). Motivational aspects were measured with the adapted Ryan and Connell Professional Motivation inventory (Osin et al, 2017). Personal resources ― stress resistance, authenticity and coping strategies ― were measured with the adapted…
A Deletion of the Nuclear Localization Signal Domain in the Fus Protein Induces Stable Post-stress Cytoplasmic Inclusions in SH-SY5Y Cells
2021
Mutations in Fused-in-Sarcoma (FUS) gene involving the nuclear localization signal (NLS) domain lead to juvenile-onset Amyotrophic Lateral Sclerosis (ALS). The mutant protein mislocalizes to the cytoplasm, incorporating it into Stress Granules (SG). Whether SGs are the first step to the formation of stable FUS-containing aggregates is still unclear. In this work, we used acute and chronic stress paradigms to study the SG dynamics in a human SH-SY5Y neuroblastoma cell line carrying a deletion of the NLS domain of the FUS protein (homozygous: ΔNLS–/–; heterozygous: ΔNLS+/–). Wild-type (WT) cells served as controls. We evaluated the subcellular localization of the mutant protein through immuno…
The Black Mediterranean: A View from Sicily
2021
While Italy has recently experienced nationalist drives, Sicily and in particular the City of Palermo, one of the major ports of refuge for countless migrants arriving in Europe from the African shores, has distinguished itself as an experimental site where to rethink and challenge notions of residence, mobility, citizenship and belonging. Through a series of cultural initiatives, Palermo has become a hub for frontline artists, writers, intellectuals, and activists who have gathered to explore the historically and contemporary ways in which black voices have been silenced and black bodies have been ambiguously imagined in Western-dominated global culture. Investigating these questions is fu…
Ann Radcliffe’s Gothic Romances and the Sea
2021
Biographical materials and the writer’s journals show that Ann Radcliffe had some personal knowledge of the sea and to some extent of sailing. She was also a lover of nature, an enthusiast of 17th -century landscapists, a connoisseur of Pre-Romantic poetry, who was also familiar with contemporary esthetic tastes and theories. In this context, the article analyzes seascapes, maritime and nautical references, motifs of storm and shipwreck in Radcliffe’s Gothic romances, including some poetical lines inspired by the sea with which The Mysteries of Udolpho is interspersed. The writer’s descriptions of the sea and her use of this element in her works are discussed in relation to her fictional ch…
Deep inelastic scattering off quark-gluon plasma and its photon emissivity
2021
The photon emissivity of quark-gluon plasma probes the interactions in the medium and differs qualitatively between a weakly coupled and a strongly coupled plasma in the soft-photon regime. The photon emissivity is given by the product of kinematic factors and a spectral function associated with the two-point correlator of the electromagnetic current at lightlike kinematics. A certain Euclidean correlator at imaginary spatial momentum can be calculated in lattice QCD and is given by an integral over the relevant spectral function at lightlike kinematics. I present a first exploratory lattice calculation of this correlator. Secondly, I show how Euclidean correlators at imaginary spatial mome…

Burnout syndrome assessment among Spanish oral surgery consultants: A two populations comparative pilot study.
2021
Background The professional Burnout Syndrome (BOS) or Burnout is considered a professional disease made up of three interrelated dimensions (emotional exhaustion, depersonalization and lack of personal fulfillment). BOS has been documented to most severely affect the healthcare professions, especially dentists. On the other hand, its appearance has been documented at an early age, during dental training. However, there are no studies that analyze its incidence in professionals dedicated to Oral Surgery and Implantology, determining the age of onset and related factors. Material and Methods The modified Maslach questionnaire was carried out anonymously among the professors and students of th…
The Synbiotic Combination of Akkermansia muciniphila and Quercetin Ameliorates Early Obesity and NAFLD through Gut Microbiota Reshaping and Bile Acid…
2021
Gut microbiota plays a key role in obesity and non-alcoholic fatty liver disease (NAFLD), so synbiotics could be a therapeutic alternative. We aim to evaluate a nutritional intervention together with the administration of the bacteria Akkermansia muciniphila and the antioxidant quercetin in an in vivo model of early obesity and NAFLD. 21-day-old rats were fed with control or high-fat diet for six weeks. Then, all animals received control diet supplemented with/without quercetin and/or A. muciniphila for three weeks. Gut microbiota, NAFLD-related parameters, circulating bile acids (BAs) and liver gene expression were analyzed. The colonization with A. muciniphila was associated with less bod…
Integration of large-area optical imagers for biometric recognition and touch in displays
2021
In recent years there has been an increasing interest to integrate optical sensing in mobile displays, for instance, for biometric fingerprint scanning functionality. There are several routes to incorporate optical fingerprint functionality within the full display area, each with their own benefits and challenges. Here we investigate the different integration routes using large-area, ultra-thin imagers based on organic photodiodes.

Chutzpadik advertising and its effectiveness: Four studies of agencies and audiences
2021
Abstract The creation of advertisements that attract immediate attention and simultaneously provoke thoughts and stimulate ongoing discussions is challenging. Hence, advertisers increasingly use Chutzpadik advertising, which we define as “radical advertising messaging that purposefully transgresses social norms and proscribed topics”. We conduct four studies to identify the dimensions and evaluate the effectiveness of Chutzpadik advertising. The first two studies involve interviews with 12 managers of advertising agencies and 22 members of the Israeli general public (audience members). The interviews reveal Chutzpadik advertising’s dimensions are norm violation, novelty, and audacity. In tw…

Transcriptomic autophagy-related gene signature investigation for type 2 diabetes in Mediterranean subjects
2021
Abstract Background Autophagy (involving degradation and clearance of damaged organelles and compounds) plays a role in type 2 diabetes (T2D). There are three main types of autophagy and several genes involved. These genes have been well studied in animal models, but there are few transcriptomic studies in humans. Our aim is to analyze the differential gene expression, and the functional enrichment of the main autophagy-related genes (ARG) in T2D subjects from a Mediterranean population Methods We analyzed 120 White-European subjects (mean age 61,4 years; 50% women; 24 T2D) from Valencia, Spain. Clinical and lifestyle data were obtained. ARN was isolated from blood. Transcriptome-wide gene …
Extension of luminance component based demosaicking algorithm to 4- and 5-band multispectral images
2021
Abstract Multispectral imaging systems are currently expanding with a variety of multispectral demosaicking algorithms. But these algorithms have limitations due to the remarkable presence of artifacts in the reconstructed image. In this paper, we propose a powerful multispectral image demosaicking method that focuses on the G band and luminance component. We've first identified a relevant 4-and 5-band multispectral filter array (MSFA) with the dominant G band and then proposed an algorithm that consistently estimates the missing G values and other missing components using a convolution operator and a weighted bilinear interpolation algorithm based on the luminance component. Using the cons…
Quick determination of Glyphosate and AMPA at sub µg/L in drinking water by direct injection into LC-MS/MS
2021
Abstract A sensitive, simple and quick method for the determination of glyphosate (Gly) and its degradation product, Aminomethyl phosphonic acid (AMPA), in water through ion chromatography coupled to quadrupole-linear ion trap mass spectrometry has been developed. Sample treatment was based on direct injection and acquisition was implemented in both MS2 and MS3 modes. The LoQs of the method were 0.03 µ/L for both Gly-and AMPA. The recoveries were between 91 and 118% and RSD was lower than 15%. The developed methodology was applied on 436 water samples.
Coupled hydro-mechanical analysis of compacted bentonite behaviour during hydration
2021
Abstract This study analyses the response of compacted bentonites upon hydration based on a coupled hydro-mechanical elasto-plastic framework. As an alternative to multi-porosity interpretation, the framework was selected based on the experimental evidence of adsorbed water behaviour in bentonites and the volumetric response at saturated states, apparently independent of its initial state. Based on these premises, a water retention model was formulated using an explicit distinction between adsorbed water and free water, enabling the postulation of the water properties and behaviour depending on its state. In order to effectively account for the transition between unsaturated to saturated st…
Use of stevia and chia seeds for the formulation of traditional and vegan artisanal ice cream
2021
Abstract Gelato is the name of the Italian-style artisanal ice cream, a nutritious product widely consumed in different parts of the world. Due to the high content in simple sugars, ice cream should be consumed moderately by diabetic patient. This research aimed to create artisanal ice cream, using Stevia rebaudiana, a plant well known for its sweet taste and its hypoglycemic effect. Traditional and vegan ice cream were formulated using stevia and chia seeds, in order to obtain products with appreciable rheological, textural and sensorial properties. Physical and sensorial properties of the ice cream formulation containing milk protein (traditional) or vegan substitute, were evaluated. Resu…

Temporal turnover of the soil microbiome composition is guild-specific.
2021
Although spatial and temporal variation are both important components structuring microbial communities, the exact quantification of temporal turnover rates of fungi and bacteria has not been performed to date. In this study, we utilised repeated resampling of bacterial and fungal communities at specific locations across multiple years to describe their patterns and rates of temporal turnover. Our results show that microbial communities undergo temporal change at a rate of 0.010-0.025 per year (in units of Sorensen similarity), and the change in soil is slightly faster in fungi than in bacteria, with bacterial communities changing more rapidly in litter than soil. Importantly, temporal deve…

Healthy ageing and Mediterranean diet: A focus on hormetic phytochemicals
2021
Abstract Mediterranean diet (MedDiet) is rich in fruits and vegetables associated with longevity and a reduced risk of several age-related diseases. It is demonstrated that phytochemicals in these plant products enhance the positive effects of MedDiet by acting on the inflammatory state and reducing oxidative stress. Evidence support that these natural compounds act as hormetins, triggering one or more adaptive stress-response pathways at low doses. Activated stress-response pathways increase the expression of cytoprotective proteins and multiple genes that act as lifespan regulators, essential for the ageing process. In these ways, the hormetic response by phytochemicals such as resveratro…

The role of shame and guilt in social anxiety disorder
2021
Abstract Research suggests that shame and guilt may play a role in anxiety disorders. For social anxiety disorder (SAD), however, only a few studies investigated patients with the primary diagnosis of SAD. Thus, further research on shame and guilt in SAD is required. A secondary analysis of Data from the SOPHO-NET multicenter treatment study was performed. In a large sample of N = 495 patients with the primary diagnosis of SAD the relationship between shame and guilt with symptoms of social anxiety, depression, and interpersonal problems was examined by means of correlation analysis and additionally, a hierarchical linear regression analysis. To assess SAD, the German version of the Structu…
Frequency dynamics of power systems with temporally distributed disturbances
2021
Abstract The frequency dynamics and stability of power systems is essentially affected by nature and characteristics of the disturbances occurring in the system. Conventionally, frequency transients are examined assuming a single disturbance applied at a given time. However, actual incidents in the power systems can be generally composed of a temporal sequence of events, and thus characterized by multiple power imbalances of different magnitudes and time offsets. The consideration of the effects of the temporal distribution of power imbalances is important for two main reasons: the impact on the frequency dynamics of the system in terms of frequency metrics such as minimum instantaneous fre…
