Location of musculoskeletal pain in musicians according to gender, academic status and instrument
Full text linkObjective. The aim is to evaluate the prevalence of musculoskeletal pain in different body locations comparing student musicians and teachers according to gender, academic status and instrument played by instrument families. Methods. observational study carried out with student musicians and teachers of higher conservatories in Spain by means of a3 questionnaire. Results. 552 valid responses were obtained. Cervical (57%), dorsal (40%) and the left shoulder (36%) are the areas with the highest prevalence. Women have a higher prevalence of pain in all the body regions studied. Students have a higher frequency of pain, with significant differences in almost all locations compared to teachers. By instrument
families, we found differences in cervical, dorsal, both upper limbs and the jaw. Woodwind instruments as well as singers suffer most often from neck pain. Conclusions. The cervical region has the highest prevalence of pain. Pain in women and students is more prevalent. It would be interesting to carry out an exercise program aimed at preventing the appearance of these injuries

El estatus oficial del bajo alemán como "lengua regional"
Full text linkEn este artículo se llevan a cabo una serie de reflexiones suscitadas a partir del nuevo estatus oficial del bajo alemán como „«lengua regional», que le fue otorgado a esta lengua en virtud de la Carta Europea de las Lenguas Regionales o Minoritarias (enero de 1999) por parte del Parlamento Europeo y el Consejo de Europa. Partiendo del concepto «lengua regional» se analizan argumentos a favor y en contra de aceptar al bajo alemán como lengua propia o como dialecto del alto alemán, llegando a la conclusión de que se trata efectivamente de una lengua. Su idiosincrasia sajona y el desarrollo que está experimentando en diversas parcelas del ámbito oral y escrito como Ausbausprache son, en nuestra opinión, pruebas claras que avalan esta decisión.This paper sets out several considerations regarding the official status of low German as «regional language». This status was conferred to it by the European Parliament and the European Council by reason of the European Charter for Regional or Minority Languages in January 1999. Working on the concept «regional language», pros and cons of considering it a language or a dialect are analyzed. Taking into account the Saxon idiosyncrasy and the development it is experiencing in different spoken and written fields as Ausbausprache, we conclude it deserves the status of language.Xunta de Galicia | Ref.

Level variability of radio signals propagating through fire: experimental measurements and results
Full text linkPublic Protection and Disaster Relief (PPDR)
communication systems play a crucial role in the avoidance and
minimization of the damages caused by wildfires and tall
building fires. These systems should have reliable coverage and
high availability in emergency scenarios. Incidents due to
degradation by fire of these radiocommunication systems have
been reported throughout their history; nonetheless, scientific
characterization of this subject is still scarce, with most of the
experimental results centered in obtaining values of the mean
attenuation and its dependency on the frequency, but not taking
into account the variability around the mean value. In this paper,
we present the results of an experiment conducted to measure the
effects of the fire on a radio link propagating through it and we
have analyzed the variation of the attenuation around its mean
value. Results show that the variation of the attenuation due to
the highly dynamic behavior of the fire is large in relation to its
mean value. Therefore, it is important to take this fact into
account for proper planning of a PPDR network. Finally,
measurement results match with previous work in that mean
attenuation increases slightly with temperature and decreases
with antenna height.European Commission | Ref. Life16 Env/ES/00055
Early Jurassic origin of avian endothermy and thermophysiological diversity in dinosaurs
Full text linkA fundamental question in dinosaur evolution is how they adapted to long-term climatic shifts during the Mesozoic and when they developed environmentally independent, avian-style acclimatization, becoming endothermic.1,2 The ability of warm-blooded dinosaurs to flourish in harsher environments, including cold, high-latitude regions,3,4 raises intriguing questions about the origins of key innovations shared with modern birds,5,6 indicating that the development of homeothermy (keeping constant body temperature) and endothermy (generating body heat) played a crucial role in their ecological diversification.7 Despite substantial evidence across scientific disciplines (anatomy,8 reproduction,9 energetics,10 biomechanics,10 osteohistology,11 palaeobiogeography,12 geochemistry,13,14 and soft tissues15,16,17), a consensus on dinosaur thermophysiology remains elusive.1,12,15,17,18,19 Differential thermophysiological strategies among terrestrial tetrapods allow endotherms (birds and mammals) to expand their latitudinal range (from the tropics to polar regions), owing to their reduced reliance on environmental temperature.20 By contrast, most reptilian lineages (squamates, turtles, and crocodilians) and amphibians are predominantly constrained by temperature in regions closer to the tropics.21 Determining when this macroecological pattern emerged in the avian lineage relies heavily on identifying the origin of these key physiological traits. Combining fossils with macroevolutionary and palaeoclimatic models, we unveil distinct evolutionary pathways in the main dinosaur lineages: ornithischians and theropods diversified across broader climatic landscapes, trending toward cooler niches. An Early Jurassic shift to colder climates in Theropoda suggests an early adoption of endothermy. Conversely, sauropodomorphs exhibited prolonged climatic conservatism associated with higher thermal conditions, emphasizing temperature, rather than plant productivity, as the primary driver of this pattern, suggesting poikilothermy with a stronger dependence on higher temperatures in sauropods.Royal Society Newton International Fellowship | Ref.

From business to legacy: the strategic role of Family Offices in family life
Full text linkObjective: The purpose of this study was to explore how Family Offices (FOs) function as relational and strategic structures designed by business families to preserve their wealth, values, and cohesion across generations. Background: Unlike traditional financial institutions, FOs place the family—not just the assets—at the center of their purpose. As business families transition away from direct business management, the FO emerges as an organizational structure to support legacy planning, intergenerational dialogue, and relational continuity. Method Through a systematic bibliometric review of 46 academic articles published between 1980 and 2024, four thematic domains in the FO literature were identified: organization and succession, investment strategies, entrepreneurship and philanthropy, and governance mechanisms. Results: Although investment remains a main theme, there is growing scholarly recognition of the FO's role in promoting family unity, educating younger generations, and transmitting values that strengthen identity and purpose. FOs may help families to manage complex emotional, generational, and financial dynamics. They serve not only as wealth management tools, but also as facilitators for intergenerational mentoring, philanthropic engagement, and conflict prevention. Conclusions: and Implications Anchored in theories of socioemotional wealth and family systems, this research shows how FOs can align financial decisions with relational well‐being and long‐term cohesion. It contributes a family‐centered perspective to the emerging field of FO studies and offers practical insights for family educators, therapists, and advisors seeking to foster family resilience and continuity in an increasingly complex socioeconomic context

Smartphone use in university students : an oportunity for learning
No full textEl elevado nivel de penetración del smartphone junto con su reducido coste de implementación en el ámbito educativo hace que el m-learning sea una tendencia en crecimiento a nivel mundial. Este artículo presenta los hábitos de uso de aplicaciones para la comunicación y el aprendizaje móvil del alumnado de educación superior e identifica factores que pueden favorecer la intención de adoptar herramientas de m-learning basadas en el smartphone entre el alumnado universitario. Para ello se administró un cuestionario basado en el modelo UTAUT2 de adopción de tecnología a 176 estudiantes de distintos cursos del Grado en Publicidad y Relaciones Públicas de la Universidad de Vigo. Los resultados muestran los principales usos que hacen los estudiantes del smartphone, sus preferencias en cuanto a la utilización del dispositivo para el aprendizaje y la importancia de la dimensión lúdica del m-learning en la intención de adoptar este modelo, un aspecto que no muchas investigaciones del campo destacan, pero que convenientemente utilizado por los docentes– puede suponer una gran oportunidad para su implementación
Chiral molecules induce enantiomorphic lattice helicity in chiral 0D tin bromide crystals
Full text linkChiral organic–inorganic hybrid metal halides have emerged as a promising class of materials for spin‐controlled optical and optoelectronic effects and related applications. Chiral hybrid metal halides generally crystallize in non‐helical space groups. Herein, we report the discovery of zero‐dimensional (0D) chiral (R/S‐MBA) 2 SnBr 6 (MBA: methylbenzylammonium cation) single crystals with enantiomorphic lattice helicity. The S‐enantiomer of the chiral molecule induces right‐handed helicity with the P6 1 space group (right‐handed, P‐helix), while the R‐enantiomer induces right‐handed helicity with the P6 5 space group (left‐handed, M‐helix). The chiral molecules induce the helical twist of inorganic units in the lattice through N─H···Br and C─H···π interactions. Density functional theory (DFT) calculations indicate that the strong electronic coupling between chiral molecules and SnBr 6 2− subunits is responsible for the generation of chirality. The chiral crystals exhibit circular dicroism (CD) spectra with a high dissymmetry factor ( g CD ) of 3.5 × 10 − 2 and no Cotton effect, maintaining the same CD sign throughout the spectrum. In addition, they exhibit broadband second harmonic generation (SHG) over a broad excitation range, with a g CP‐SHG up to 0.44. Furthermore, we find that the alloying of Sn with Pb leads to a change in dimensionality from 0D to non‐helical 1D structures. These crystals with helical lattices and interesting CD responses are expected to open new avenues for spin‐controlled applications.Agencia Estatal de Investigación | Ref.

Macroevolutionary processes in turtles (Testudines): a view from biomic specialization and historical climatic changes
Full text linkThe resource-use hypothesis proposed by Elisabeth S. Vrba suggests that lineages display varying tendencies toward generalism or specialization in biome occupancy, with a tendency towards the accumulation of specialists due to their higher rate of speciation through vicariance. It also posits differences in biome occupancy patterns driven by the environmental characteristics of biomes, with a higher presence of biome specialist species in biomes that are placed in the extremes of the global climatic gradients. Here, we tested this hypothesis in turtles, a very ancient and morphologically stable lineage, representing a remarkable diversity with 357 species, many of which are threatened with extinction. We analyzed the resource-use hypothesis in a phylogenetic context within the Testudines lineage. For this purpose, a presence/absence matrix was compiled for all species across all 10 terrestrial biomes. Their distribution across biomes was contrasted with 10,000 Monte Carlo simulations. The relationship between diversification rates and both the biomic specialization index and the biomes occupied by specialists species was evaluated. The results demonstrate strong consistency with Vrba`s hypothesis, revealing a higher number of biome specialist species than expected by chance, with a significant accumulation of species in tropical ecosystems. These trends also were observed for ecological groups (terrestrial and freshwater species). In addition, higher diversification rates were observed for biome specialist species, although the particular biome occupied did not significantly influence their diversification rates.Dirección General de Investigaciones of Universidad Santiago de Cali | Ref.
