Hacia una teoría crítica del periodismo deportivo: (des)mercantilización de la profesión, la información y los públicos
(Estudios sobre el Mensaje Periodístico, 2025) Pedro Carañana, Joan; Vázquez Márquez, Israel; Miller, Toby
En las últimas décadas, se ha desarrollado un rico corpus de investigaciones críticas sobre periodismo deportivo que, sin embargo, no ha llevado aún a la formulación explícita de una teoría crítica de esta especialización informativa. En este artículo queremos contribuir a llenar este vacío presentando algunos fundamentos para el desarrollo de dicha teoría. A partir de un marco teórico y una metodología de crítica dialéctica, discutimos y articulamos las dimensiones explicativa, normativa y práctica de la teoría crítica del periodismo deportivo. Para ello, partimos de un punto de entrada clásico de la teoría crítica como es el concepto de mercantilización. En este caso, nos centramos en la mercantilización de la profesión, la información y los públicos del periodismo deportivo, lo que permite abordar la producción, los contenidos, la distribución y el consumo periodísticos. La teoría crítica explica que hay una sinergia hegemónica entre la dificultad de la profesión para mantener su autoridad cultural, la producción de información comercial y acrítica, y el tratamiento de los públicos como consumidores. Al mismo tiempo, muestra la importancia de un enfoque normativo que favorezca la desmercantilización de las diferentes dimensiones del periodismo deportivo. Por último, la teoría crítica busca retroalimentarse con prácticas colectivas justas, por lo que recogemos experiencias de periodismo deportivo independiente que tratan de alejarse de la lógica mercantil. Concluimos que este marco teórico está orientado a la expansión de la libertad creativa del periodismo deportivo en condiciones de igualdad y diversidad, pero señalamos que hay una necesidad teórico-práctica de diseño de políticas públicas que permitan reformas estructurales de democratización y humanización de los sistemas de medios.
Dpp of posterior origin patterns the proximal region of the wing
(Mechanisms of Development, 2008) Foronda, David; Pérez-Garijo, Ainhoa; Martín Castro, Francisco Antonio
The decapentaplegic (dpp) gene encodes a long-range morphogen that plays a key role in the patterning of the wing imaginal disc of Drosophila (Nellen, D., Burke, R., Struhl, G. and Basler, K. 1996. Direct and long-range action of a DPP morphogen gradient. Cell 85, 357–368.). The current view is that dpp is transcriptionally active in a narrow band of anterior compartment cells close to the anterio-posterior (A/P) compartment border. Once the Dpp protein is synthesised, it travels across the A/P border and diffuses forming concentration gradients in the two compartments (reviewed in Lawrence, P.A., Struhl, G. 1996. Morphogens, compartments, and pattern: lessons from drosophila? Cell 85, 951–961.). We have found a new site of dpp expression in the posterior wing compartment which appears during the third larval period. This source of Dpp signal generates a local gradient of Dpp pathway activity, which is independent of that originating in the anterior compartment. We show that this posterior tier of Dpp activity is functionally required for normal wing development: the elimination of dpp expression in the posterior compartment results in defective adult wings in which pattern elements such as the alula and much of the axillary cord are not formed. Moreover, these structures develop normally in the absence of anterior dpp expression. Thus the normal wing pattern requires distinct Dpp organizer activities in the anterior and posterior compartments. We further show that, unlike the anterior dpp expression domain, the posterior one is not dependent on Hedgehog activity but is dependant on the activity of the IRO complex gene mirror. Since there is a similar expression in the haltere disc, we suggest that this late appearing posterior Dpp activity may be an attribute of dorsal thoracic discs.
Mitigation of ruminal methane production with enhancing the fermentation by supplementation of different tropical forage legumes
(Environmental Science and Pollution Research, 2021) Aragadvay-Yungán, Ramón Gonzalo; Barros-Rodríguez, Marcos; Ortiz Vera, Luis Tomás; Carro, María Dolores; Navarro Marcos, Carlos; Elghandour, Mona Mohamed Mohamed Yasseen; Salem, Abdelfattah Zeidan Mohamed
The aim of this research was to evaluate the influence of forage species adapted to the tropical region of Ecuador on gas production, enteric methane, digestion, and ruminal fermentation. The tree forage evaluated were C. arborea, E. fusca, B. forficata, E. poeppigiana, C. argentea, G. sepium, C. tora, and F. macrophylla. Ruminal fluid of four adult sheep fistulated with permanent cannulas in the rumen was used in the in vitro gas production technique. The in vitro gas production parameters were lower (P < 0.05) in the C. arborea (A = 41.68 mL gas/g DM, c = 0.044%/h and Lag = 1.654 h) and the average gas production rate for B. forficata was 1.017 mL/h (P < 0.05). C. arborea presented higher (P = 0.0001) effective degradation and real DM digestibility (40.461 g/kg and 82.51 mg/g, respectively). With respect to VFA, the highest (P < 0.05) proportion of acetic, propionic, and butyric was observed in C. arborea, G. sepium, and E. poeppigiana (72.52, 23.09, and 7.44 mol/100 mol, respectively) and the lowest (P = 0.0001) ratio: acetic/propionic was observed in G. sepium (2.92 mol/100 mol). The content of NH3-N (mg/L) showed no difference. The lowest (P = 0.0001) methane production was observed in C. arborea (1.23 mL CH4/g DM). The use of forage species of tropical climate rich in secondary metabolites in ruminant diets has the capacity to reduce the gas production and enteric methane; however, this is at the expense of the reduction of the fermentation of organic matter in the rumen
CYP epoxygenase-derived H2O2 is involved in the endothelium-derived hyperpolarization (EDH) and relaxation of intrarenal arteries
(Free Radical Biology and Medicine, 2017) Muñoz Picos, Mercedes; López-Oliva Muñoz, María Elvira; Pinilla, Estéfano; Martínez Sainz, María Del Pilar; Sánchez Pina, Ana Alejandra; Rodríguez Prados, Claudia; García Sacristán, Albino; Hernández Rodríguez, Medardo Vicente; Rivera De Los Arcos, Luis; Prieto Ocejo, Dolores
Reactive oxygen species (ROS) like hydrogen peroxide (H2O2) are involved in the in endothelium-derived hyperpolarization (EDH)-type relaxant responses of coronary and mesenteric arterioles. The role of ROS in kidney vascular function has mainly been investigated in the context of harmful ROS generation associated to kidney disease. The present study was sought to investigate whether H2O2 is involved in the endothelium-dependent relaxations of intrarenal arteries as well the possible endothelial sources of ROS generation involved in these responses. Under conditions of cyclooxygenase (COX) and nitric oxide (NO) synthase inhibition, acetylcholine (ACh) induced relaxations and stimulated H2O2 release that were reduced by catalase and by the glutathione peroxidase (GPx) mimetic ebselen in rat renal interlobar arteries, suggesting the involvement of H2O2 in the endothelium-dependent responses. ACh relaxations were also blunted by the CYP2C inhibitor sulfaphenazole and by the NADPH oxidase inhibitor apocynin. Acetylcholine stimulated both superoxide (O2•-) and H2O2 production that were reduced by sulfaphenazole and apocynin. Expression of the antioxidant enzyme CuZnSOD and of the H2O2 reducing enzymes catalase and GPx-1 was found in both intrarenal arteries and renal cortex. On the other hand, exogenous H2O2 relaxed renal arteries by decreasing vascular smooth muscle (VSM) intracellular calcium concentration [Ca2+]i and markedly enhanced endothelial KCa currents in freshly isolated renal endothelial cells. CYP2C11 and CYP2C23 epoxygenases were highly expressed in interlobar renal arteries and renal cortex, respectively, and were co-localized with eNOS in renal endothelial cells. These results demonstrate that H2O2 is involved in the EDH-type relaxant responses of renal arteries and that CYP 2C epoxygenases are physiologically relevant endothelial sources of vasodilator H2O2 in the kidney.

(Biochemical Pharmacology (BCP), 2021) Miras Portugal, María Teresa; Ortega De La O, Felipe; Gómez Villafuertes, María Rosa; Gualix Sánchez, Francisco Javier; Pérez Sen, Raquel; García Delicado, Esmerilda
For the past three decades, our laboratory has conducted pioneering research to elucidate the complexity of purinergic signaling in the CNS, alone and in collaboration with other groups, inspired by the ground-breaking efforts of Geoffrey Burnstock. This review summarizes our contribution to understand the nucleotide receptor signaling in the CNS with a special focus on the P2X7 receptor.
Innovative didactic learning formats: have they improved dental education? A systematic review and meta-analysis
(International Endodontic Journal, 2025) Arias Paniagua, Ana María; Min-Seock, Seo; Gancedo Caravia, Lucía; Fernandez-Garcia, Isabel; Pérez-Higueras Sánchez-Escalonilla, Juan
Background: New learning methods require higher professor-to-student ratios, increased faculty preparation time, continuous professional development for educators, and expanded physical spaces within university settings. Objectives: This systematic review aimed to answer the following PICO question: In dental students (P), what is the effectiveness of innovative formats of learning (I) in comparison with traditional formats (C) in terms of educational outcomes and satisfaction (O)? Methods: After PROSPERO protocol registration, a literature search was conducted using Web of Science (WoS), Scopus, PubMed and Cochrane Central Register of Controlled Trials. Selection of studies was performed in a three-step process: identification, screening and eligibility. Data was extracted and analysed qualitatively and quantitatively. A random-effects meta-analysis was conducted to provide an estimate of the effect of innovative teaching formats in dental education. Additionally, subgroup analyses were performed to investigate potential differences in effectiveness based on the type of innovative teaching intervention. Results: One hundred and nineteen studies matched the inclusion criteria and were included in the systematic review. A meta-analysis of 23 studies (1074 students in the control and 1021 in the experimental group) revealed significant differences in favour of innovative teaching methods (p < 0.00001) with considerable heterogeneity (χ2 = 297.46, p < 0.00001; I2 = 93%). Subgroup analysis also revealed significantly different results depending on the innovative teaching approach (p = 0.02). Both asynchronous independent learning and synchronous learning, either in a large group with the whole class of students using blended learning or in small groups, resulted in a significantly better outcome than traditional learning (overall effect: Z = 5.85; p < 0.00001); however, synchronous blended learning showed a significantly better outcome than the rest of the subgroups (mean difference = 16.59; 95% CI = 9.03-24.15). The quality of the studies varied, with some facing methodological challenges such as inconsistent outcome measurement, which can impact the generalisability of the findings. Conclusions: Innovative strategies lead to superior knowledge acquisition in comparison with traditional methods. Subgroup analyses favoured synchronous blended learning, but both asynchronous independent learning and synchronous learning formats, whether implemented in large-group settings via blended approaches or in small-group environments, are more effective than traditional instruction.
Quantum projections on conceptual subspaces
(Cognitive Systems Research, 2023) Martínez Mingo, Alejandro; Jorge Botana, Guillermo de; Martinez Huertas, Jose Angel; Olmos, Ricardo
One of the main challenges of cognitive science is to explain the representation of conceptual knowledge and the mechanisms involved in evaluating the similarities between these representations. Theories that attempt to explain this phenomenon should account for the fact that conceptual knowledge is not static. In line with this thinking, many studies suggest that the representation of a concept changes depending on context. Traditionally, concepts have been studied as vectors within a geometric space, sometimes called Semantic-Vector Space Models (S-VSMs). However, S-VSMs have certain limitations in emulating human biases or context effects when the similarity of concepts is judged. Such limitations are related to the use of a classical geometric approach that represents a concept as a point in space. Recently, some theories have proposed the use of sequential projections of subspaces based on Quantum Probability Theory (Busemeyer and Bruza, 2012; Pothos et al., 2013). They argue that this theoretical approach may facilitate accounting for human similarity biases and context effects in a more natural way. More specifically, Pothos and Busemeyer (2011) proposed the Quantum Similarity Model (QSM) to determine expectation in conceptual spaces in a non-monotonic logic frame. To the best of our knowledge, previous data-driven studies have used the QSM subspaces in a unidimensional way. In this paper, we present a data-driven method to generate these conceptual subspaces in a multidimensional manner using a traditional S-VSM. We present an illustration of the method taking Tversky’s classical examples to explain the effects of Asymmetry, Triangular Inequality, and the Diagnosticity by means of sequential projections of those conceptual subspaces.
Typology of young people in digital environments: identifying vulnerability patterns
(Social Sciences & Humanities Open, 2025) Narros González, María José; Carcelén García, Sonia Laura; Pedreño Santos, Ana
Young people have naturally transferred a large part of their daily activities to the digital environment, a space that contributes to the construction of their identity and personal maturity. Despite the intensive use that young people make of the Internet and social networks, they are not aware of the dangers that can be found on the network, which makes them a vulnerable audience that must be protected. To improve their knowledge of these issues, it is important to address young people with an understanding of their specific characteristics. The aim of this study is to identify a typology of young people according to sociodemographic criteria, behaviors, selfperception of risk and self-protection mechanisms used in the digital context, to determine their level of vulnerability in this environment. For this purpose, a quantitative study is carried out through an online survey of a representative sample of 300 Spanish young people between 14 and 16 years old. The results of the research locate four segments of young users: “cautious connected” (50.3 %), “regular and exposed in social networks” (25.8 %), “sporadic beginners” (12.1 %), “active in shopping and digital entertainment” (11.8 %)". The findings show that age, frequency of use of social networks and the Internet, the number and type of applications used, and the perception of online risks, discriminate the digital vulnerability of young people and influence their maturity and the self-protection mechanisms they use.
Current applications of 3D printing in dental implantology: A scoping review mapping the evidence
(Clinical Oral Implants Research, 2023) Pradíes Ramiro, Guillermo Jesús; Morón Conejo, Belén; Martínez Rus, Francisco; Salido Rodríguez-Manzaneque, María Paz; Berrendero Dávila, Santiago
Objectives: This scoping review aimed to identify the available evidence in the use of 3D printing technology in dental implantology. Due to the broad scope of the subject and its application in implantology, three main areas of focus were identified: (1) customized dental implants, (2) manufacturing workflow for surgical implant guides, and (3) related implant-supported prostheses factors, which include the metallic primary frameworks, secondary ceramic or polymer superstructures, and 3D implant analog models. Materials and methods: Online databases (Medline, Cochrane, Embase, and CINAHL) were used to identify the studies published up to February 2023 in English. Two experienced reviewers performed independently the screening and selection among the 1737 studies identified. The articles evaluated the additive manufacturing (AM) technology, materials, printing, and post-processing parameters regarding dental implantology. Results: The 132 full-text studies that met the inclusion criteria were examined. Thirteen studies of customized dental implants, 22 studies about the workflow for surgical implant guides, and 30 studies of related implant-supported prostheses factors were included. Conclusions: (1) The clinical evidence about AM titanium and zirconia implants is scarce. Early data on survival rates, osseointegration, and mechanical properties are being reported. (2) 3D printing is a proven manufacturing technology to produce surgical implant guides. Adherence to the manufacturer's instructions is crucial and the best accuracy was achieved using MultiJet printer. (3) The quality of 3D printed prosthetic structures and superstructures is improving remarkably, especially on metallic alloys. However, better marginal fit and mechanical properties can be achieved with milling technology for metals and ceramics.
Bridging the theoretical gap between semantic representation models without the pressure of a ranking: Some lessons learnt from LSA
(Cognitive Processing, 2020) Jorge Botana, Guillermo de; Olmos, Ricardo; Luzón Encabo, José María
In recent years, latent semantic analysis (LSA) has reached a level of maturity at which its presence is ubiquitous in technology as well as in simulation of cognitive processes. In spite of this, in recent years there has been a trend of subjecting LSA to some criticisms, usually because it is compared to other models in very specific tasks and conditions and sometimes without having good knowledge of what the semantic representation of LSA means, and without exploiting all the possibilities of which LSA is capable other than the cosine. This paper provides a critical review to clarify some of the misunderstandings regarding LSA and other space models. The historical stability of the predecessors of LSA, the representational structure of word meaning and the multiple topologies that could arise from a semantic space, the computation of similarity, the myth that LSA dimensions have no meaning, the computational and algorithm plausibility to account for meaning acquisition in LSA (in contrast to others models based on online mechanisms), the possibilities of spatial models to substantiate recent proposals, and, in general, the characteristics of classic vector models and their ease and flexibility to simulate some cognitive phenomena will be reviewed. The review highlights the similarity between LSA and other techniques and proposes using long LSA experiences in other models, especially in predicting models such as word2vec. In sum, it emphasizes the lessons that can be learned from comparing LSA-based models to other models, rather than making statements about “the best.”

Editorial for special issue: nanostructured surfaces and thin films synthesis by physical vapor deposition
(Nanomaterials, 2021) Palmero, Alberto; Alcalá Penadés, Germán; Álvarez, Rafael
The scientific interest in the growth of nanostructured surfaces and thin films by means of physical vapor deposition (PVD) techniques has undoubtedly increased in the last decade [1]. Even though some of them can be considered mature, as they were first implemented and analyzed a few decades ago [2], the progressive understanding of fundamental atomistic phenomena [3,4], as well as their popularity in the technological industry, have prompted the scientific community to propose novel growth methodologies/geometries which, based on the classic approaches, have bestowed an even larger versatility in terms of nanostructural possibilities. In this way, film nanostructures that were unthinkable years ago are now possible by PVD: for instance, a classical technique such as the magnetron sputtering (MS) deposition method, that originally aimed to produce highly compact coatings, is currently being explored for the production of highly porous thin films thanks to the oblique angle deposition geometry [5,6]. Moreover, an MS-based methodology named High Power Impulse Magnetron Sputtering (HiPIMS) is employing high power pulsed electromagnetic signals to produce highly compact films, expanding the classic methodology [7]. Hence, it can be said that the research and application of PVD techniques are living a scientific golden age due to the large amount of exciting new possibilities, fundamental discoveries, and the numerous potential applications based on their wide range of morphological characteristics and properties, e.g. in photovoltaic cells [8], tribological coatings [9,10], optofluidic sensors [11], energy storage [12], etc. Unfortunately, the processes responsible for the formation of a certain nanostructure by PVD are, in most of the cases, not yet known with the sufficient depth to gain enough level of control to optimize its functionality when incorporated into devices. It is then necessary to study novel nanostructures and their properties as well as the nanostructuration mechanisms, by addressing fundamental issues to understand them. In this special number, ten research works analyze various relevant aspects concerning new approaches and methodologies based on classic PVD techniques to produce films with singular nanostructures and morphologies, representing the current state of the art in this research field. Among them, two important review papers are included allowing any potential reader to understand the most relevant advances in the following two different topics. In ref. [13] the growth of metallic ultra-thin films by continuous dynamic monitoring is reviewed in depth, by combining in situ and real-time optical and electrical probes to analyze the first stages of growth in the MS deposition of a large number of metals with different crystalline structures. In ref. [14], a review on the growth of nanostructured surfaces with plasmonic properties, obtained by the combination of nanosphere lithography and PVD, is presented. There, the authors analyze the recent advances linking the fabrication routes, the film nanostructure and its plasmonic properties, with special emphasis on its application for the early detection of hepatocellular carcinoma using surface-enhanced Raman scattering and controlling the growth of Ag nanoparticles. In addition to these relevant review manuscripts, two original research works are presented [15,16]. In ref. [15] the authors study nanostructured thin films grown by MS deposition at oblique angles, in this case using tungsten. These films are characterized by a porous structure consisting of tilted nanocolumns. By varying the deposition conditions, the tilt angle, thickness and separation of these columns can be affected, which in turn affects the optical, electrical or mechanical properties of the film. Here, the authors study the effect of both the film thickness and the gas pressure within the deposition chamber on properties such as the electrical resistivity of the film, or the anisotropy of the propagation of 2-dimensional elastic waves along the film. They have found that anisotropy rises at low pressures, where the columnar structures are better defined and more tilted, and that it increases with the thickness of the film. Electrical resistivity was found to decrease with the film thickness and to increase with the gas pressure, due to changes in the crystallinity of the film. A thorough characterization of AZO (Al-doped zinc oxide) thin films deposited by radio frequency (RF) MS is covered in ref. [16]. Sheet resistance, thin film thickness, resistivity, hall mobility, carrier concentration, optical transmittance, and band gap energy were determined for these transparent and conducting thin films as a function of the substrate position within the substrate holder with a 3 mm spatial resolution, for varying conditions of pressure, applied power, and substrate-target distance. The results show a great resistivity dependence with the substrate position, varying about 2 orders of magnitude within a distance of 10 mm. Contrarily, the spatial profile of the transmittance is quite homogenous along the surface of the samples. A reduction of the energetic oxygen ions coming from the erosion track of the target is proposed as a way to produce more homogenous films. Other works included here focus on fundamental analysis, while also targeting a specific application, such as sensors [17,18], solar cells [19], or biomedicine [20]. In ref. [17] the authors synthesize composite TiO2-Ag2O nanorods to be used as chemoresistive sensors for the detection of trace amounts of NO2 gas. TiO2 nanorods were first prepared by hydrothermal methods, and then RF-MS of an Ag target in presence of oxygen was used to deposit Ag2O on the TiO2 nanorods with different degrees of coverage. The gas-sensing performance of the composite nanorods, when the coverage was made in the form of discrete Ag2O particles, was found to be superior to that of pristine TiO2 nanorods and even other TiO2-Ag2O sensors previously reported in the literature. Contribution [18] presents a novel technique that improves Ag nanorods substrates used for surface-enhanced Raman scattering (SERS), rising their sensibility by four times and increasing their thermal stability range by more than 100 ºC. The technique consists of the deposition of an ultrathin capping Al2O3 layer on the top of the Ag nanorods, followed by the deposition of an additional Ag capping layer on top of the previous one. The Al2O3 layer improves thermal stability, while the last Ag layer boosts the SERS sensitivity. The Ag nanorods and the capping layers were grown using the electron-beam evaporation deposition technique at oblique angles. A detailed study of the growth of nano-sculpted thin films by the MS technique in glancing angle deposition configuration is displayed in ref. [19]. The effects of key deposition parameters, such as the deposition angle, the gas pressure within the reactor, the temperature of the substrate or the way the substrate is rotated during deposition are experimentally studied, and found to be in agreement with numerical simulations of the film growth. Film properties such as the tilt angle of the grown nanocolumns, the film porosity and, in some cases, its composition and crystalline phase, are also characterized. Finally, the authors propose the integration of nano-sculpted TiO2 coatings into the photo-anode of dye-sensitized solar cells, concluding that a hybrid system incorporating both nanocolumns and nanoparticles significantly improves their efficiency. In ref. [20] a novel experimental methodology to produce porous thin films by MS on large surfaces is tested as an alternative to typical oblique angle deposition geometries. For this, two-side implant plates with areas up to 15 cm2 were coated with Ti nanocolumns using an industrial reactor. While this was already achieved on small surfaces using laboratory reactors, the relevance of this paper resides on the development of a new geometrical approach to achieve the oblique incidence on industrial reactors as well as the homogeneous coating of a large area plate with Ti nanocolumns. Moreover, the authors demonstrate that the functionality of the obtained porous Ti coatings is maintained, exhibiting the same antibacterial properties as those produced at the laboratory. Finally, important applications based on these films are developed for thin film transistors [21] or photovoltaic solar cells [22]. In ref. [21] the authors describe a way to improve the performance and stability of indium–gallium–zinc–oxide (IGZO) thin-film transistors (TFTs), which are widely used in active-matrix displays. By pretreating the substrate (a SiO2 buffer layer) with F-plasma in a reactive ion etching chamber before depositing a 30 nm IGZO layer by magnetron sputtering, they describe the formation of indium fluoride nanoparticles in the interface, which increases the density of the IGZO, thus improving mobility and bias stability of these oxide TFTs, and allowing for their fabrication at lower temperatures. In order to improve the characteristics and efficiency of a photovoltaic solar cell, in ref. [22] the authors introduce a Cu2ZnSnSe4 (CZTSe) nano-layer between the metallic (Mo) electrode contact layer and the active absorbing perovskite layer (MAPbI3). This nano-layer was deposited by RF-MS and was later subjected to an annealing process, which greatly improved its hole mobility and its role as heterojunction layer. As derived from the ten works presented in this special number, the PVD technology comprises a family of several deposition techniques, each one of them embracing a number of different geometric configurations and deposition parameters with a direct effect on the nanostructure, morphology and properties of the produced film. It also allows deposition of most metals and many ceramic materials on a wide variety of substrates, since the deposition temperature is low enough to avoid modifications during the process on most substrate material candidates. Additionally, this is a technology with an important presence in several industrial sectors, which confirms that many scalability and production issues are already overcome. All these features provide the possibility of new developments in a huge range of possible applications, some of them already broadening like among others solar cell components, electronic and photonic applications, gas, liquid and pressure sensors and actuators, biosensors, cell-surface interaction, piezoelectric nanogenerators, electrochromic applications, water splitting fuel cells and hydrogen storage, Li-ion batteries, photovoltaic applications, surface controlled wettability, nanocarpet effect, anisotropic wetting, etc. However, in order to reach a given surface nanostructure and architecture, and its consequent set of desired properties, a deep understanding at an atomistic level of the deposition processes taking place in both the gaseous and the solid phases involved is needed. The works published in this special number represent an excellent illustration of the recent achievements reached by means of the combination of fundamental/applied experimental research and numerical modelling, increasing this knowledge and enabling the progress in new tailored nanostructured surfaces and thin films. The potential that these developments suggest for the future of surface engineering can only be glimpsed nowadays.
Cell Competition: The Embrace of Death
(Developmental Cell, 2007) Morata, Ginés; Martín Castro, Francisco Antonio
Cell competition compares cells within a growing population and eliminates the weaker ones by apoptosis. In a recent issue of Cell, Li and Baker (2007) show in the Drosophila wing disc that cells fated to die induce in neighboring cells the activity of engulfment genes, whose function is essential to complete the apoptotic program.
Numidian Kings and Numidian Garrisons during the Second Punic War: Coins and History
(Potestas, 2010) López Sánchez, Fernando
Las series monetales de plata con Apolo con un caballo encabritado y letras púnicas fueron acuñadas en Agrigento en los años 211/210 a.C.2 Estuvieron destinadas al principal cuerpo de caballería númida presente en Sicilia, a las órdenes de Mottones. Otras series monetales con el caballo encabritado, esta vez de bronce y con Perséfone/Démeter, fueron acuñadas en Morgantina y estuvieron pensadas para un destacamento númida más pequeño, presente en esta ciudad durante estos mismos años. Mottones luchó en Sicilia, primero del lado de Cartago y contra Roma, y después del lado de Roma contra Cartago, y este cambio de alianzas es perceptible en sus series sicilianas. Las emisiones de Apolo con el caballo encabritado en el reverso proporcionan una excelente guía para el seguimiento de todas las guarniciones númidas de Aníbal y Mottones en Italia durante la segunda guerra púnica. Estas guarniciones se localizaron en Capua-Monte Tifata, Arpi, Salapia, Thurium, Larinum, Benevento y Luceria en distintos momentos entre los años 216 y 208/7 a.C. Las series hispanas con el caballo encabritado fueron acuñadas en Cartago Nova en los años 212/211-209 y estuvieron destinadas a las tropas númidas de Masinisa.
The 5th Century Hoard of Theodosian Solidi from Stora Brunneby, Öland, Sweden: A Result from the LEO Project
(Fornvännen, 2011) Fischer, Svante; Victor, Helena; López Sánchez, Fernando
The Stora Brunneby hoard of 17 solidi with a terminus post quem of 451 is presented and analysed as a preliminary result of the LEO Project. Its type composition and the coins' average weight are quite unusual and support that he Stora Brunneby hoard is likely to have been accumulated over some time, with at least two generations contributing to it in the first half of the 5th century. The hoard may be the result of a series of payments especially related to quinquennial vota, which should perhaps be seen as occasions for the rotation of military units between Scandinavia and Italy.
Can personality traits be measured by analyzing written language? A meta-analytic study on computational methods
(Personality and Individual Differences, 2021) Moreno, José David; Martínez Huertas, José Ángel; Olmos, Ricardo; Jorge Botana, Guillermo de; Botella, Juan
In the last two decades, empirical evidence has shown that personality traits could be related to the characteristics of written language. This study describes a meta-analysis that synthesizes 23 independent estimates of the correlations between the Big Five major personality traits, and some computationally obtained indicators from written language. The results show significant combined estimates of the correlations, albeit small to moderate according to Cohen's conventions to interpret effect sizes, for the five traits (between r = 0.26 for agreeableness and neuroticism, and 0.30 for openness). These estimates are moderated by the type of information in the texts, the use of prediction mechanisms, and the source of publication of the primary studies. Generally, the same effective moderators operate for the five traits. It is concluded that written language analyzed through computational methods could be used to extract relevant information of personality. But further research is still needed to consider it as predictive or explanatory tool for individual differences.
The mediating role of reflective functioning in the association between childhood trauma and suicide attempt
(Journal of Psychiatric Research, 2024) Andreo Jover, J.; De La-Torre Luque, Alejandro Francisco; Díaz Marsa, Marina Francisca; Fernández Rodrigues, Verónica; Pemau Gurumeta, Andrés; Diaz Carracedo, Patricia Cristina; Saiz González, María Dolores; Ayad Ahmed, Wala; Carrasco Perera, José Luis
Background: Childhood trauma is intimately related with suicidal behaviour. Patients who have suffered childhood trauma develop impaired Reflective Functioning (RF), which refers to the capacity to understand ourselves and others in terms of intentional mental states. An improvement in RF has been associated with a reduction in suicidal attempts, but the mediating role of RF between childhood trauma and suicidal behaviour has not been addressed so far. Objective: We aim to examine the potential mediating effect of RF among childhood trauma and suicide attempts. Method: We included 748 patients who had attempted suicide at least once. They were asked to complete the Reflective Functioning Questionnaire (RFQ-8), the Columbia-Suicide Severity Rating scale (CSSRS), and the Childhood Trauma Questionnaire-Short Form (CTQ-SF). We conducted linear regressions by simple mediating model to examine the role of RF in the indirect association between childhood trauma and the number of suicide attempts. Results: Our results show significant indirect effects through hypo and hypermentalizing between Emotional Abuse (EA) and Sexual Abuse (SA) in childhood and the number of suicide attempts in lifetime. These results indicate that ineffective RF significantly mediates the association between childhood trauma and suicidality. Conclusion: This is the first study supporting the mediational role of RF in the relationship between EA and SA, and the number of suicide attempt in lifetime. These findings have important implications for reducing suicide rates and preventing future re-attempts. Further studies analysing this mediating role and focusing efforts on increasing RF-based interventions are required.

The aim of this study was to examine the levels of depression, anxiety, and suicidal ideation among health care professionals who sought professional help for psychological problems during the COVID-19 pandemic. These psychopathological constructs were measured using the PHQ-2, the GAD-2, and the suicide item from the PHQ-9, respectively, in a sample of 238 health care professionals who contacted a nationwide psychological helpline. Findings show that 52.5% had clinical levels of depression, 71% had clinical levels of anxiety, and 7.1% reported suicidal ideation, with no differences across health care roles (nurses, physicians, other roles). These figures, for depression and anxiety, are two to three times higher than those found in the general population of health care professionals during the pandemic but are similar for suicidal ideation. The results also indicate a higher prevalence of clinical levels of depression and anxiety among professionals who were currently receiving or had received professional help for psychological problems (67.2% and 84.6%, respectively). These findings confirm global concerns about the psychological impact of the pandemic on health care professionals and underscore the importance of integrating mental health into future health crisis response planning.
