Cassandra and A Room of One's Own: A common cry of frustration
No full textIn this manuscript, we explore the connections between Florence Nightingale's Cassandra and Virginia Woolf's A Room of One's Own while taking the authors' personal and social contexts into account. We conduct a detailed textual analysis from a feminist perspective. Cassandra and A Room of One's Own exhibit singular textual commonalities, such as evidence of trauma, the integration of myth and fiction as literary devices aimed at facilitating the author's access to various social spheres, the use of interpellations to impact the audience, and an argument for education as a path by which privileged women can enter the public realm. Both authors' personal wounds and intellectual frustrations influenced their work, thus making their writing very powerfu
The role of experience and diversity on research consortia’ performance: an exploratory approach
No full textIn the realm of academic engagement, this study directs its focus toward a policy instrument that has received surprisingly scant attention within the literature, despite its substantial investment: European Union-funded research projects. These projects are designed to foster collaboration and establish a framework that supports and fortifies the creation and dissemination of exceptional knowledge and cutting-edge technologies. These endeavors are anticipated to fuel economic growth, spur social development, and address global challenges. Within this study, we delve into the impact of team experience and diversity on the research performance of consortia — groups of organizations — that have been successfully awarded funding within the FP7 and H2020 funding schemes. In order to dissect the influence of learning, our analysis is confined to consortia that have collaborated on multiple occasions. Drawing from data sourced from Community Research and Development Information Service, our findings unveil that beyond the monetary allocation, an array of team attributes and environmental factors play a role in augmenting team performance
Changes in urinary metabolomic profile show the effectiveness of a nutritional intervention in children 6–12 years old: The ALINFA study
No full textDiet plays an essential role in health and disease. Therefore, its determination is an
important component of many investigations. The aim of the study was to evaluate
the effect of a nutritional intervention on the urinary metabolome in children aged
6–12 years. Also, it was intended to identify biomarkers of diet quality and dietary
intake. A 2-month, randomized, controlled, parallel trial was conducted in Spanish children. The analyses focused on the ALINFA group, which followed a full-fixed meal
plan including healthy products, ready-to-eat meals, and healthy recipes. Diet quality
was assessed by the KIDMED index and dietary intake by a food frequency questionnaire. Untargeted metabolomic analysis on urine samples was carried out, and
multivariate analyses were performed for pattern recognition and characteristic metabolite identification. PLS-DA and Volcano plot analyses were performed to identify
the discriminating metabolites of this group. 12 putative metabolites were found to
be the most relevant to this intervention. Most of them were products derived from
protein and amino acid metabolism (N-Ribosylhistidine, indolacrylic acid, and peptides)
and lipid metabolism (3-oxo-2-pentylcyclopentane-1-hexanoic acid methyl, SuberoylL-carnitine, and 7-Dehydrodichapetalin E). All these metabolites decreased after the
intervention, which was mainly associated with a decrease in the consumption of fatty
meat and total fat, especially saturated fat. In turn, N-Ribosylhistidine and SuberoylL-carnitine were negatively associated with diet quality, as well as able to predict the
change in KIDMED index. In conclusion, the changes observed in urinary metabolome
demonstrate the effectiveness of the ALINFA nutritional intervention
Hydrolysis of riboflavins in root exudates under iron deficiency and alkaline stress
No full textRiboflavins are secreted under iron deficiency as a part of the iron acquisition Strategy I, mainly when the
external pH is acidic. In plants growing under Fe-deficiency and alkaline conditions, riboflavins have been reported to accumulate inside the roots, with very low or negligible secretion. However, the fact that riboflavins
may undergo hydrolysis under alkaline conditions has been so far disregarded. In this paper, we report the
presence of riboflavin derivatives and products of their alkaline hydrolysis (lumichrome, lumiflavin and carboxymethylflavin) in nutrient solutions of Cucumis sativus plants grown under different iron regimes (soluble Fe-EDDHA in the nutrient solution, total absence of iron in the nutrient solution, or two different doses of FeSO4
supplied as a foliar spray), either cultivated in slightly acidic (pH 6) or alkaline (pH 8.8, 10 mM bicarbonate)
nutrient solutions. The results show that root synthesis and exudation of riboflavins is controlled by shoot iron
status, and that exuded riboflavins undergo hydrolysis, especially at alkaline pH, with lumichrome being the
main product of hydrolysis
Parentalidad, diferenciación del self y agresión entre iguales en adolescentes de países hispanohablantes.
No full textIntroducción:
La agresión entre iguales durante la adolescencia es un problema que cada vez preocupa más. Para prevenirla, es importante conocer los factores que influyen sobre ella. El objetivo de este trabajo fue evaluar la asociación que la parentalidad positiva y la diferenciación del self tienen con la agresión entre pares durante la adolescencia, en países hispanohablantes. Específicamente, se quería averiguar si la diferenciación del self tiene un papel moderador y/o mediador en la asociación entre parentalidad positiva y agresión entre pares.
Métodos:
Se pasó un cuestionario online a 7170 adolescentes (12-17 años) de Argentina, Chile, Ecuador, España, México y Perú. El cuestionario evaluaba la parentalidad, la diferenciación y la presencia de agresión sufrida o ejercida. A través de regresiones logísticas univariantes y multivariantes, y de modelos de ecuaciones estructurales (SEM), se evaluó la asociación entre estas variables.
Resultados:
El afecto parental y las dimensiones de la diferenciación del self (reactividad emocional y la distancia emocional) se asociaron con menor frecuencia de agresión sufrida y ejercida, tanto entre chicos como entre chicas. No se apreció papel de la exigencia parental. No se apreció papel moderador de reactividad o distancia emocional en la asociación entre afecto parental y agresión sufrida o ejercida. En la asociación entre afecto parental y agresión sufrida o ejercida se encontró un efecto directo y un efecto indirecto, mediado por la reactividad emocional y por la distancia emocional.
Conclusiones:
Los resultados sugieren que el afecto parental se asocia con una menor frecuencia de agresión, y que la diferenciación del self media parcialmente dicha asociación
Interactions between struvite and humic acid and consequences on fertilizer efficiency in a nonacidic soil
No full textThe effect of humic acid extracted from peat (AHt) on improving the struvite (STR) fertilizing efficiency is explored.
To this end, a soil incubation study is correlated to plant assays comparing STR, STR-AHt, and superphosphate (SSP).
Characterization techniques confirm the incorporation of the AHt into the STR. The P-pool distribution of STR and SSP is similar
in the soil incubation, with STR-AHt presenting a higher labile P at 90 days passing from 10 to 15% P from SSP and STR to 25% P
with STR-AHt. However, when applied to barley and tomato, STR yields more shoot P content, aboveground biomass, and residual
P in soil than SSP. STR-AHt does not improve the STR results. The poor correlation observed between soil incubation and plant
trials highlights the role of the rhizosphere in testing the fertilizer efficiency of STR. Mechanistic assays indicate the key role of
rhizosphere pH. Finally, molecular modeling reveals a higher stabilization of STR with AHt, which could reduce P release decreasing
the fertilizing potential of STR-AHt, as observed in the pot trials

Development and validation of a realistic type III esophageal atresia simulator for the training of pediatric surgeons
No full textBackground The technical complexity and limited casuistry of neonatal surgical pathology limit the possibilities of developing the necessary technical competencies by specialists in training. Esophageal atresia constitutes the paradigm of this
problem. The use of synthetic 3D models for training is a promising line of research, although the literature is limited.
Methods We conceptualized, designed, and produced an anatomically realistic model for the open correction of type III
oesophageal atresia. We validated it with two groups of participants (experts and non-experts) through face, construct, and
content-validity questionnaires.
Results The model was validated by nine experts and nine non-experts. The mean procedure time for the experts and non-experts groups was 34.0 and 38.4 min, respectively. Two non-experts did not complete the procedure at the designed time
(45 min). Regarding the face validity questionnaire, the mean rating of the model was 3.2 out of 4. Regarding the construct
validity, we found statistically signifcant diferences between groups for the equidistance between sutures, 100% correct in the
expert group vs. 42.9% correct in the non-expert group (p=0.02), and for the item “Confrms that tracheoesophageal fstula
closure is watertight before continuing the procedure”, correctly assessed by 66.7% of the experts vs. by 11.1% of non-experts
(p=0.05). Concerning content validity, the mean score was 3.3 out of 4 for the experts and 3.4 out of 4 for the non-experts.
Conclusions The present model is a cost-efective, simple-to-produce, and validated option for training open correction of type III
esophageal atresia. However, future studies with larger sample sizes and blinded validators are needed before drawing defnitive
conclusions
