Imaxinar o florecemento colectivo no monte galego
No full textGalicia is a region in the Northwest of Spain currently credited as producing more than half of the country’s timber, with further industrial growth expected as the bioeconomy gains legitimacy. However, the future of the monte (the Galician landscape) is contested, with differing visions and practices emerging across a range of actors. This PhD project examines how the monte is imagined as a site for desirable futures by engaging with three distinct groups (activists, local communities, and state forestry), using an interactional co-productionist approach and the framework of sociotechnical imaginaries. The aim of this thesis is to better understand how competing ideas about the monte circulate, gain traction, and are negotiated to both loosen up current debates about the future of the Galician monte and engage constructively with work in political ecology concerning forestry.
Theoretically, the thesis draws on interactional co-production to explore how certain actions and practices in the monte materialize while others do not. The sociotechnical imaginaries framework introduces a normative dimension to this analysis, offering insight into why visions of the future are stabilized or contested. The study expands this framework by engaging with vanguard visions from marginal actors, highlighting the multiplicity of knowledge claims and competing imaginaries shaping the Galician monte.
Methodologically, the research is grounded in ethnographic fieldwork. I engage with comunidades de montes vecinales en man común, which govern around 25% of Galician territory as common lands. Field visits and in-depth qualitative research were carried out in the communities of Mourente (Pontevedra), Froxán (A Coruña), and Lentille (Ourense). In parallel, I engaged with a group of anti-eucalyptus activists called the Brigadas Deseucaliptizadoras, with whom I undertook 12 actions in different places in Galicia to understand how a seemingly unique practice of destroying trees on a voluntary basis arises to bring about a desirable future. Complementing these participatory engagements, I conducted a literature review of work in the realm of forestry science to trace how the monte has historically been imagined as a source of national prosperity and how such imaginaries have shaped its material transformation over time. These historical transformations are further engaged with through interviews and documents that shed light on how community actors resisted and interacted with institutional imaginaries to enact their particular visions of the monte.
This thesis contributes to political ecology literature by analyzing how knowledge is mobilized and negotiated across diverse actors and institutional sites to legitimize particular visions of the monte. It responds to calls for greater attention to historical contingency in environmental governance, challenging the totalizing tendencies of environmentality and neoliberal nature critiques. By extending the sociotechnical imaginaries framework to the field of forestry, an area rarely studied through this lens, and focusing on a Global North context, the research broadens current understandings of how forests function as arenas of political, epistemic, and ecological contestation.Galicia es una región del noroeste de España que actualmente se reconoce por producir más de la mitad de la madera del país, con un crecimiento industrial adicional previsto a medida que la bioeconomía gana legitimidad. Sin embargo, el futuro del monte (el paisaje gallego) es objeto de disputa, con diferentes visiones y prácticas que emergen entre una variedad de actores. Este proyecto de doctorado examina cómo se imagina el monte como un espacio para futuros deseables mediante el trabajo con tres grupos distintos (activistas, comunidades locales y el sector forestal estatal), utilizando un enfoque de coproducción interaccional y el marco de los imaginarios sociotécnicos. El objetivo de esta tesis es comprender mejor cómo circulan las ideas en competencia sobre el monte, cómo adquieren fuerza y cómo se negocian, con el fin de abrir los debates actuales sobre el futuro del monte gallego y contribuir de manera constructiva al trabajo en ecología política relacionado con la silvicultura.
Desde un punto de vista teórico, la tesis se apoya en la coproducción interaccional para explorar cómo ciertas acciones y prácticas en el monte se materializan mientras que otras no. El marco de los imaginarios sociotécnicos introduce una dimensión normativa en este análisis, ofreciendo una visión de por qué algunas visiones de futuro se estabilizan o se disputan. El estudio amplía este marco al involucrarse con visiones de vanguardia de actores marginales, resaltando la multiplicidad de reivindicaciones de conocimiento e imaginarios en competencia que configuran el monte gallego.
Metodológicamente, la investigación se basa en trabajo de campo etnográfico. He trabajado con las comunidades de montes vecinales en man común, que gestionan aproximadamente el 25% del territorio gallego como tierras comunales. Se realizaron visitas de campo e investigaciones cualitativas en profundidad en las comunidades de Mourente (Pontevedra), Froxán (A Coruña) y Lentille (Ourense). Paralelamente, colaboré con un grupo de activistas antieucalipto denominado Brigadas Deseucaliptizadoras, con quienes participé en 12 acciones en diferentes lugares de Galicia para comprender cómo surge una práctica aparentemente singular —la destrucción voluntaria de árboles— como medio para alcanzar un futuro deseable. Como complemento a estos compromisos participativos, realicé una revisión bibliográfica sobre estudios en el ámbito de la ciencia forestal, con el fin de rastrear cómo el monte ha sido históricamente imaginado como fuente de prosperidad nacional y cómo tales imaginarios han moldeado su transformación material a lo largo del tiempo. Estas transformaciones históricas se profundizan mediante entrevistas y análisis de documentos que arrojan luz sobre cómo los actores comunitarios resistieron e interactuaron con los imaginarios institucionales para poner en práctica sus propias visiones del monte.
Esta tesis contribuye a la literatura de ecología política al analizar cómo se moviliza y negocia el conocimiento entre diversos actores y espacios institucionales para legitimar determinadas visiones del monte. Responde a los llamamientos para prestar mayor atención a la contingencia histórica en la gobernanza ambiental, desafiando las tendencias totalizadoras de la “ambientalidad” y de las críticas a la naturaleza neoliberal. Al extender el marco de los imaginarios sociotécnicos al ámbito de la silvicultura —un área raramente estudiada desde esta perspectiva— y centrarse en un contexto del Norte Global, la investigación amplía la comprensión actual de cómo los bosques funcionan como arenas de disputa política, epistémica y ecológica.Galicia é unha rexión do noroeste de España recoñecida actualmente por producir máis da metade da madeira do país, cun crecemento industrial adicional previsto a medida que a bioeconomía gaña lexitimidade.

Valorized S/N-doped banana peel biochar as a sustainable OER electrocatalyst for green energy applications
Get PDFDecarbonization necessitates innovative energy solutions, such as H2 production through water splitting reactions,
which critically relies on efficient catalysts to enhance both efficiency and cost-effectiveness. Employing
carbocatalysts synthesized from agro-industrial residues and co-doped with nitrogen and sulfur represents a
groundbreaking strategy that not only supports decarbonization efforts but also accelerates the transition towards
a circular economy model. In this study, we have developed a novel oxygen evolution reaction (OER) ecoelectrocatalyst
by doping banana peel-derived biochar with varying levels of thiourea. The optimal ecoelectrocatalyst,
5 %-S/N@BC, significantly surpasses the efficiency of IrO2 and outperforms many reported
carbon-based electrodes in terms of initial performance and long-term stability. Notably, it achieves overpotentials
of 290, 322, and 334 mV at current densities of 10, 50, and 100 mA cm����� 2, respectively, over 30-h
periods. The process has been optimized regarding pH, catalyst dose, and dopant concentration. Furthermore,
the eco-electrocatalyst demonstrates a competitive overall water splitting behavior, attaining a notably low cell
voltage of 1.58 V required for reaching 10 mA cm����� 2. Comprehensive characterization using FTIR, Raman, XRD,
XPS, and SEM-EDS have been conducted to validate these findings. This represents the first demonstration of a
metal-free S/N@BC catalyst derived from banana peel for efficient OER. Our research highlights the significance
of avoiding precious and transition metals, as well as the value of creating carbon-based catalysts fully sourced
from biomass. The development of such materials plays a crucial role in advancing sustainable catalyst design
while fostering a circular economy through the effective utilization of agro-industrial waste. Furthermore, only a
limited number of studies have focused solely on biomass-derived materials, and among those, their catalytic
performance rarely exceeds the results demonstrated in this work.Xunta de Galicia | Ref. ED481B-109Universidade de Vigo/CISUGAgencia Estatal de Investigación | Ref. PID2020-113667GB-I00Agencia Estatal de Investigación | Ref. RYC2023-044934-IUniversidade de Vig
The title-page in eighteenth-century grammar books
Get PDFTheories of paratext have focused primarily on fiction texts, following Gérard Genette’s Paratexts (1997). Recent work in the field of historical sociolinguistics has paid increasing attention to grammar writing, in particular that from the eighteenth century. This study aims to contribute to both areas of research, and to book history in general, by examining the linguistic design of the title-page, one of the richest paratextual elements, in eighteenth-century grammar books, a type of non-fiction text that played a vital role in the education and print culture of that century. The analysis is based on a corpus of title-pages in English grammars, leading to a better understanding of which elements of a book’s title-page, which pedagogical method and which grammar contents were considered essential to present to readers directly. The choice of lexicon will also reveal to what extent a prescriptive tone was overtly presented to readers as a selling point.Ministerio de Ciencia e Innovación | Ref.

Localización de videojuegos: fundamentos traductológicos innovadores para nuevas prácticas profesionales | 1ª ed
No full textIntroducción. Generalmente, cuando se habla de localización de videojuegos, la gente suele quedarse con el término videojuego y preguntarse dónde se debían encuadrar: ¿En el área de humanidades, en el área de las ciencias...? Esta suele ser una pregunta sin respuesta, pero que tiene una gran relevancia. A nivel académico todavía no se ha sabido ubicar a los videojuegos en el lugar que les corresponde; en muchos casos, incluso se los ignora como posible elemento de estudio. Pero la pregunta persiste, por más que se intente obviar y posponer: de todas las posibles ramas del saber y el conocimiento humano, ¿dónde se encuadraría un producto tan novedoso, relativamente reciente y complejo como un videojuego?.

Protection of contemporary mural artwork: Evaluation of a fixing primer and colour protectors
Get PDFApplication of a fixing layer prior to the paint or/and posterior application of a colour protector are conservation strategies used in contemporary murals to reduce the deterioration of the artwork when exposed outdoors agents, mainly solar radiation and humidity.
In this study, the physical, chemical and mineralogical changes in 4 alkyd (yellow, pink, orange and green) and 2 acrylic (fluorescent orange and fluorescent green) paints applied to concrete mock-ups were evaluated under different conditions. Concrete test slabs were coated with a fixing layer prior to application of the paint and/or posterior application of a protector (2 different acrylic colour protectors). Samples were exposed to the QUV accelerated weathering test for 1512 h. Colour monitoring was carried out during the test. A multi-analytical evaluation protocol based on stereomicroscopy, contact angle measurement, peeling test, X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy was used to assess the physical, chemical and mineralogical changes in the samples after the exposure period.
The findings revealed that the green alkyd paint was most resistant to colour changes, while the orange alkyd and the fluorescent acrylic paints (orange and green) underwent the most noteworthy colorimetric changes. Unexpectedly, the fixing layer did not slow down the colorimetric changes in the paints. Although there were some differences in the performance of the products evaluated, applying a colour protector can help to conserve murals but can also affect the original colour of the paint.Universidade de Vigo/CISUGEuropean Union | Ref. 2017 – 3674/001 – 001Agencia Estatal de Investigación | Ref.

Influence of short-to-continuous and continuous photoperiods combined with elevated temperatures on sexual maturation in lumpfish (Cyclopterus lumpus, L. 1758)
Get PDFWe tested the photothermal effects on sexual maturation in the broodstock of lumpfish (Cyclopterus lumpus) using
short-to-continuous (LDL) and continuous (LL) photoperiods for 24 weeks, with temperature elevation during
final maturation in females. The lumpfish sexual maturation was phased differently between the two photoperiods,
while temperature elevation enhanced the photoperiod changes. Female gonadosomatic index (GSI), and
plasma levels of testosterone (T), 11-ketotestosterone (11-KT) and 17β-estradiol (E2) increased under LDL, and
temperature elevation enhanced the sex steroid levels in both photoperiods. While the brain expressions of gnrh2
decreased in females exposed to LDL compared to LL groups, the ovarian expressions of fshr, lhr, vtgr, and
cyp19a1 changed significantly at ambient temperatures in LL and LDL groups and at elevated temperature in the
LL group. A high proportion of males were sexually mature from the start of the experiment, and a prolonged
period with sexually mature males was observed in the ambient temperature LL group. This was revealed by
elevated GSI, T, 11-KT, as well as brain expression of gnrh2 at the start of the experiment, with the highest
presence of spermatozoa, and pronounced fluctuations in T and 11-KT throughout the experiment with significant
changes observed only in LL0T. Brain expressions of gnrh2 and testicular expressions of fshr and lhr declined
more rapidly in LDL compared to LL groups. With temperature elevation, gnrh2 expressions were enhanced in
both LL and LDL. Despite exposure to different photothermal regimes, gonadal development and selected
endocrine factors remained stage-coherent. Ovarian expressions of fshr, lhr, vtgr, cyp19a1 and E2 levels increased
up to oocyte maturation and decreased at ovulation, while GSI, T and 11-KT increased until ovulation. Testicular
fshr and lhr expressions peaked at spermatocyte stage and decreased subsequently, while plasma levels of T and
11-KT increased until the spermatid stage and decreased at the spermatozoa stage. In this study, we show that
while photoperiods phase lumpfish sexual maturation, temperature has an important role in cueing the final
stages leading to spawning. Additionally, the gonadal development and endocrine factors remain stage-coherent
though at different rates in different photothermal regimes
Anthropometric profile in different event categories of acrobatic gymnastics
Get PDFThere is a specific anthropometric profile for each sport, which may be differentiated even in relation to the position, role or event category within each sport discipline. However, there are few studies on acrobatic gymnastics, and the goal of this work was to determine the anthropometric profile depending on the event category, as well as factors that predisposed to performance in these categories. The sample consisted of 150 gymnasts from Spain, divided into 8 groups according to the event category and the role played. The kinanthropometric measurements were taken through the procedures established by the International Society for the Advancement of Kineantropometry. The anthropometric characteristics, including body mass index, somatotype, body composition and proportionality using the Phantom stratagem were analyzed, and the results obtained from the different groups were compared. A regression analysis was performed with particular groups of gymnasts. No significant differences ( p < 0.05) were observed between groups of female tops or male bases, although differences were found between female group bases and female pair bases. It could be suggested that higher values of body height, sitting height, the minimum abdominal circumference, percentage of fat and low biliocristal breadth predispose female bases to work in pairs rather than in groups. The conclusion is that the anthropometric measurements are not decisive when guiding a gymnast toward choosing one event category or another, except for female bases
Urban vegetation decline under Brachychiton discolor f. Muell. tree
Get PDFBrachychiton discolor F.Muell. (Malvaceae) is a deciduous ornamental tree native to Australia, which has gained ecological significance in urban ecosystems worldwide. This study evaluates the impact of leaf litter from B. discolor canopies on ground cover and plant diversity in urban environments. Areas under B. discolor canopies exhibited significant reductions in the cover of Cynodon dactylon (L.) Pers., Euphorbia hirta L., Malva parviflora L., Medicago polymorpha L., Melilotus indicus (L.) All., Poa annua L., and Sisymbrium irio L., along with Shannon-Wiener diversity (H') and evenness indices (E) declined. Moreover, leaf litter from B. discolor increased soil organic matter by 18.6% and enhanced the concentrations of certain nutrients, including potassium (16.24%) and copper (11.07%), in the affected urban soils. Greenhouse experiments demonstrated that leaf residues of B. discolor significantly inhibited C. dactylon germination (by 37.1%) and reduced the establishment of C. dactylon (by 54.6%) and M. parviflora (by 58.64%). This tree much reduced the light intensity under the tree canopy. High-performance liquid chromatography analysis identified key phenolic and flavonoid allelochemicals, including ellagic acid, pyrogallol, and benzoic acid among phenolics and kaempferol among flavonoids. These results suggested that reduced vegetation cover and diversity under B. discolor are primarily driven by its leaf litter and shading effects. The allelopathic impact of its chemical compounds appeared more pronounced than its mechanical effects. Consequently, B. discolor significantly alters urban vegetation cover and diversity, highlighting the need for conservation strategies to mitigate its impact and protect urban ecosystems
The ECEG database
Get PDFThis article describes the aims, methodology and contents of the Eighteenth-Century English Grammars database online (ECEG). Starting with the definition of the term ‘English grammar’ in ECEG, which frames and sets the limits of what has been included in and excluded from the database, we then offer a detailed discussion of its design, compilation and annotation procedures. While describing the data coded in twenty-one individual relational fields, the article also hints at the potential avenues that the classification in ECEG opens up for academic research and educational purposes.British Academ
