COVID-19 Infection among Nursing Students in Spain: The Risk Perception, Perceived Risk Factors, Coping Style, Preventive Knowledge of the Disease and Sense of Coherence as Psychological Predictor Variables: A Cross Sectional Survey
The exploration of patterns of health beliefs about COVID-19 among nursing students may be beneficial to identify behaviors, attitudes and knowledge about contagion risk. We sought to analyze the variables of risk perception, perceived risk factors, coping style, sense of coherence and knowledge of preventive measures as possible predictors of having suffered from COVID-19. Participants were nursing students from 13 universities in Spain. Sociodemographic and health variables were collected. To test the independent variables, the Perception Risk Coping Knowledge (PRCK-COVID-19) scale was created and validated because there was no specific survey for young people adapted to the pandemic situation of COVID-19. It was validated with adequate psychometric properties. A total of 1562 students (87.5% female, mean age 21.5 +/- 5.7 years) responded. The high perception of the risk of contagion, the high level of knowledge and a coping style focused on the situation were notable. Significant differences by gender were found in the coping styles, problem-focused, avoidance and knowledge scales, with women scoring higher in all categories. The multiple regression analysis was significant (F = 3.68; p < 0.001). The predictor variables were the coping styles subscale search for support and the intrinsic and extrinsic perceived risk factors. Our model predicts that nursing students with a social support-based coping style are at a higher risk of becoming infected with COVID-19, based on their own health belief model
Characterization of the accessible genome in the human malaria parasite Plasmodium falciparum
Human malaria is a devastating disease and a major cause of poverty in resource-limited countries. To develop and adapt
within hosts Plasmodium falciparum undergoes drastic switches in
gene expression. To identify regulatory regions in the parasite
genome, we performed genome-wide profiling of chromatin
accessibility in two culture-adapted isogenic subclones at four
developmental stages during the intraerythrocytic cycle by using
the Assay for Transposase-Accessible Chromatin by sequencing
(ATAC-seq). Tn5 transposase hypersensitivity sites (THSSs)
localize preferentially at transcriptional start sites (TSSs).
Chromatin accessibility by ATAC-seq is predictive of active
transcription and of the levels of histone marks H3K9ac and
H3K4me3. Our assay allows the identification of novel regulatory
regions including TSS and enhancer-like elements. We show that
the dynamics in the accessible chromatin profile matches
temporal transcription during development. Motif analysis of
stage-specific ATAC-seq sites predicts the in vivo binding sites
and function of multiple ApiAP2 transcription factors. At last,
the alternative expression states of some clonally variant genes
(CVGs), including eba, phist, var and clag genes, associate with
a differential ATAC-seq signal at their promoters. Altogether,
this study identifies genome-wide regulatory regions likely to
play an essential function in the developmental transitions and
in CVG expression in P. falciparum
Effects of the Ketogenic Diet on Muscle Hypertrophy in Resistance-Trained Men and Women: A Systematic Review and Meta-Analysis
Reviews focused on the ketogenic diet (KD) based on the increase in fat-free mass (FFM)
have been carried out with pathological populations or, failing that, without population differentiation.
The aim of this review and meta-analysis was to verify whether a ketogenic diet without
programmed energy restriction generates increases in fat-free mass (FFM) in resistance-trained participants.
We evaluated the effect of the ketogenic diet, in conjunction with resistance training, on
fat-free mass in trained participants. Boolean algorithms from various databases (PubMed, Scopus.
and Web of Science) were used, and a total of five studies were located that related to both ketogenic
diets and resistance-trained participants. In all, 111 athletes or resistance-trained participants (87 male
and 24 female) were evaluated in the studies analyzed. We found no significant differences between
groups in the FFM variables, and more research is needed to perform studies with similar ketogenic
diets and control diet interventions. Ketogenic diets, taking into account the possible side effects, can
be an alternative for increasing muscle mass as long as energy surplus is generated; however, their
application for eight weeks or more without interruption does not seem to be the best option due to
the satiety and lack of adherence generated.University of Malaga (Campus of International Excellence Andalucia Tech

Game jams as valuable tools for the development of 21st-century skills
The concept of 21st-century skills refers to the knowledge, skills, and emotions that are critical to successfully navigating today’s world. Game jams can act as spaces to develop these skills and thus boost cooperative learning, problem-based learning, or co-creation. Additionally, game jams offer opportunities to improve collaboration and creativity skills, among others. This paper summarizes three years of activities designing and studying game jams to develop 21st-century skills, focused on Mexican students aged 12–16 years old. Data were compiled through direct observation, open-ended questionnaires, and interviews and were subject to thematic analysis in order to construct new knowledge on a previously underexplored topic. The results suggest that game jams are valuable tools to develop 21st-century skills, and, although the outcomes of skill evaluation may vary and may be difficult to verify, the participants reported increased skills, such as creativity or collaboration. Finally, this paper provides recommendations based on the research and practice conducted by the authors on how to use game jams to develop 21st-century skills and different ways to organize game jams, along with the resources neededPeer ReviewedPostprint (published version
Filosofía y poesía en Hölderlin
No puede entenderse la poesía de Hölderlin sin el diálogo que éste establece con la tradición filosófica, en especial con autores como Platón, Spinoza, Kant, Schiller o Fichte. Sin embargo, para el poeta alemán la filosofía acaba mostrando sus insuficiencias frente a la poesía: mientras que la intuición intelectual es inalcanzable por vía racional y filosófica, ésta puede alcanzarse a través de lo estético. Con todo, la propia evolución de la obra del poeta alemán le lleva a éste a cuestionar la posibilidad de que la poesía pueda ser una respuesta definitiva a las escisiones que separan al yo de la naturaleza, de los otros y de sí mismo. En este contexto, cobra una gran importancia el tema del alejamiento de los dioses, que no sólo supone probablemente una versión débil de la muerte de Dios, entre la nostalgia y la espera, sino asimismo una advertencia contra todo intento de encarnar el puesto vacante de la divinidad
Functions and Characteristics of Music in Sound Fiction in the Case of RNE and Podium Podcast
The objective of this article is to know the importance of music whitin sound fiction on RTVE and Podium Podcast. With a mixed methodological approach, qualitative in terms of observation and interpretation of data and quantitative in terms of data collection, analysis, statistics and comparisons.

Vortex formation for a non-local interaction model with Newtonian repulsion and superlinear mobility
We consider density solutions for gradient flow equations of the form , where is the
Newtonian repulsive potential in the whole space with the
nonlinear convex mobility , and . We show that
solutions corresponding to compactly supported initial data remain compactly
supported for all times leading to moving free boundaries as in the linear
mobility case . For linear mobility it was shown that there is a
special solution in the form of a disk vortex of constant intensity in space
supported in a ball that spreads in time like , thus
showing a discontinuous leading front or shock. Our present results are in
sharp contrast with the case of concave mobilities of the form
, with studied in [9]. There, we developed a
well-posedness theory of viscosity solutions that are positive everywhere and
moreover display a fat tail at infinity. Here, we also develop a well-posedness
theory of viscosity solutions that in the radial case leads to a very detail
analysis allowing us to show a waiting time phenomena. This is a typical
behavior for nonlinear degenerate diffusion equations such as the porous medium
equation. We will also construct explicit self-similar solutions exhibiting
similar vortex-like behaviour characterizing the long time asymptotics of
general radial solutions under certain assumptions. Convergent numerical
schemes based on the viscosity solution theory are proposed analysing their
rate of convergence. We complement our analytical results with numerical
simulations ilustrating the proven results and showcasing some open problems
