- Abstract
[ES] Este artículo presenta la propuesta de Educación para el Desarrollo que se recoge en la Estrategia para la Educación no formal de la ciudad de Valencia y su relación con los Objetivos de Desarrollo Sostenible (ODS). El contenido de la Estrategia se basa en tres ejes fundamentales: 1) un enfoque territorial en el barrio o distrito; 2) la importancia de la coordinación entre actores municipales y las ONGD para desarrollar las propuestas educativas y 3) una serie de temáticas y metodologías prioritarias. La correspondencia de la Estrategia con los ODS ha sido interpretada empleando un marco de análisis pensado para la innovación transformadora. Esta interpretación distingue entre ODS que definen los sistemas sociotécnicos o áreas de aplicación, los que definen la direccionalidad y los que indican las condiciones de contexto. Esta interpretación puede contribuir a aumentar la reflexión sobre los objetivos de transformación de las acciones educativas de una manera sinérgica, evitando perspectivas compartimentadas. Por otro lado, pone de manifiesto la importancia de las redes y coordinación entre actores y la ciudad y sus barrios. Estos son los espacios que necesitan ser transformados y a partir de los cuales pueden partir las transformaciones, [EN] This article presents the relationship between the Strategy of Non-Formal Development Education of the city of Valencia and the Sustainable Development Goals (SDG). The content of the Strategy is based on three fundamental axes: 1) a territorial approach in the neighbourhood or district; 2) the importance of coordination between municipal actors and NGDOS to develop educational proposals and 3) a series of priority themes and methodologies. The correspondence of the Strategy with the SDGS has been interpreted using an analytical framework designed for transformative innovation. This interpretation distinguishes between SDGS that define socio-technical systems or areas of application; those that define directionality and those that indicate context conditions. This interpretation can contribute to increase the reflection on the transformatory potential of educational actions in a synergic way, avoiding compartmentalized perspectives. On the other hand, it highlights the importance of networks and coordination between actors in the city and its neighbourhoods. These are the spaces that need to be transformed and from which transformations can start

- Abstract
Este documento ha permitido incorporar los contenidos de la Educación para la Ciudadanía Global en las acciones que se impulsan desde cada uno de los espacios educativos no formales dependientes de l’Ajuntament de València. Pensar hoy las ciudades requiere asumir consciente y críticamente el marco global en el que están insertas. Esta perspectiva global olvida, en demasiadas ocasiones, no sólo el papel de las organizaciones no gubernamentales, sino también a otros sujetos institucionales, como las ciudades. Sin embargo, en los últimos años, asistimos a un proceso que parece revertir esta lógica. Las ciudades están ganando protagonismo en el ámbito global porque son ellas, en gran medida, el sujeto productor de las políticas al servicio de la vida. Las ciudades son cruciales en este proceso de transformación global y van a ser determinantes en el signo que éste tome. Por ello es fundamental que València se dote de un instrumento como el que presentamos. Una herramienta al servicio de las y los actores llamados a participar en la construcción de la ciudad más justa y más consciente de las implicaciones de los procesos globales que nos afectan. En este proyecto colectivo, la totalidad de agentes contamos. Quienes la habitamos, la vivimos y la creamos y la recreamos; con cada acción que emprendemos y con cada decisión que tomamos. Todo nuestro actuar repercute en la ciudad, también en el mundo. Un actuar que requiere del apoyo de las instituciones y, en especial, de los ayuntamientos, que en su condición de mayor proximidad a la ciudadanía tienen la responsabilidad de facilitar espacios de pensamiento, de reflexión y de aprendizaje, para introducir la perspectiva global en la acción local. Los espacios municipales de ámbito no formal son un entorno idóneo para ofrecer a la ciudadanía herramientas que le ayuden a generar pensamiento crítico, global y responsable. Unas herramientas al servicio de una ciudad más justa, solidaria, igualitaria e intercultural. Este documento

- Abstract
[EN] Understanding the physical and material characteristics of our historical cities is essential for the preservation of their hereditary and cultural values. Beyond the historical logic of the urban scene and its functional nature, the city is sensed through the spaces, which it creates and configures. The spaces of the historical city represent the soul of its history and the final result of its development. Through the architectural configuration of these spaces, we can visualize the historical and vital logic that underlies the city, the heritage of the people and cultures that make it up. The Study for the Recovery of Urban Spaces in Valencia Historical Center is an interdisciplinary project of intervention in patrimonial architecture, aiming to recover the original image of spaces in the historical city center. This is a project started in 1995 and ended in 2013, which is formed by a series of activities in which both, the Polytechnic University of Valencia as a research institution and the public administrations involved in the processes of regeneration and restoration of the historic center, take part. The aim of the project has been the start-up of a dynamic restoration process of the city's historic urban centre and its landscape value. By combining scientific studies, tasks of awareness and sensitization of population, it aims to determine the formal and chromatic characteristics of original spaces that create the architecture of the city.

- Abstract
[EN] Sharing research data is an increasingly necessary requirement for the advancement of science. The aim of this study was to analyse the policies on openness in sharing scientific research data in substance abuse journals. Journals included in the Substance abuse area of the Journal Citation Reports were used for the analysis, with reference to the instructions to authors published on the journals websites. In 67.6% of the journals, it is possible to store materials in thematic or institutional repositories; 47% accept supplemental material; 64.7% allow the reuse of data, and 41.2% admit the publication of their data on a website. Most journals recommend that authors deposit their data in a repository, but they do not provide clear instructions for doing so. No association was found between the value of a journal s impact factor and the storage and reuse. PubMed Central is the repository primarily suggested for deposit.

- Abstract
[EN] The Silk Exchange of Valencia, Spain, is one of the best examples of late Gothic civil architecture in Europe, and was declared a World Heritage Monument by UNESCO in 1996. Prior to cleaning and conservation, technical examination identified the original pigments used to paint the walls, keys, vaults, arches and columns in the main hall, the Contract Hall. Cross sections of remnants of original colour (blue, green, red, gold, etc.) were investigated with optical microscopy, scanning electron microscopy with energy dispersive X-ray analysis, X-ray diffraction techniques and UV light. The study has revealed that the original paint today remains only in very limited areas. Evidence for a later maintenance operation of repainting was also found in the inscription that runs around the Contract Hall. The information has been very useful for deciding on the cleaning and conservation process.

This is an author's accepted manuscript of an article published in “Journal of Earthquake Engineering"; Volume 14, Issue 2, 2010; copyright Taylor & Francis; available online at: http://dx.doi.org/10.1080/13632460903086069, The aim of this study was to apply Nakamura s technique to Valencia city center, after some preliminary tests in Barcelona. Previous studies of Barcelona had measured periods in restrictive conditions and in various types of material ranging from very soft soil (with a predominant period of approximately 2 s) to rock (0.3 s), and under different measurement conditions. The Valencia city center measurements were taken by using the distance from buildings and car and pedestrian traffic to construct a measurement grid that was as regular as possible. We also estimated possible soil-structure interaction to detect potential vulnerability.

- Abstract
Climate change affects all ecosystems, but subterranean ecosystems are repeatedly neglected from political and public agendas. Cave habitats are home to unknown and endangered species, with low trait variability and intrinsic vulnerability to recover from human-induced disturbances. We studied the annual variability and cyclicity of temperatures in caves vis-à-vis surface in different climatic areas. We hypothesize that cave temperatures follow the average temperature pattern at the surface for each location with a slight delay in the signal, but we found three different thermal patterns occurring in caves: (1) high positive correlation and a similar thermal pattern to the surface, (2) low correlation and a slight thermal delay of the signal from the surface, and (3) high negative correlation with an extreme delay from the surface. We found daily thermal cycles in some caves, which may potentially control the circadian rhythms of cave organisms. Our results show that caves had lower thermal amplitude than the surface, and that thermal averages within caves approximately correspond to the to the annual average of surface temperature. Caves buffer external temperature and act as refugia for biota in extreme climatic events. Likewise, temperature increases at surface will lead to increment in caves, threatening subterranean biota and ecosystem services., (© 2023. The Author(s).)

- Abstract
Soil organisms drive major ecosystem functions by mineralising carbon and releasing nutrients during decomposition processes, which supports plant growth, aboveground biodiversity and, ultimately, human nutrition. Soil ecologists often operate with functional groups to infer the effects of individual taxa on ecosystem functions and services. Simultaneous assessment of the functional roles of multiple taxa is possible using food-web reconstructions, but our knowledge of the feeding habits of many taxa is insufficient and often based on limited evidence. Over the last two decades, molecular, biochemical and isotopic tools have improved our understanding of the feeding habits of various soil organisms, yet this knowledge is still to be synthesised into a common functional framework. Here, we provide a comprehensive review of the feeding habits of consumers in soil, including protists, micro-, meso- and macrofauna (invertebrates), and soil-associated vertebrates. We have integrated existing functional group classifications with findings gained with novel methods and compiled an overarching classification across taxa focusing on key universal traits such as food resource preferences, body masses, microhabitat specialisation, protection and hunting mechanisms. Our summary highlights various strands of evidence that many functional groups commonly used in soil ecology and food-web models are feeding on multiple types of food resources. In many cases, omnivory is observed down to the species level of taxonomic resolution, challenging realism of traditional soil food-web models based on distinct resource-based energy channels. Novel methods, such as stable isotope, fatty acid and DNA gut content analyses, have revealed previously hidden facets of trophic relationships of soil consumers, such as food assimilation, multichannel feeding across trophic levels, hidden trophic niche differentiation and the importance of alternative food/prey, as well as energy transfers across ecosystem compartments. Wider adoption of such tools and the development of open interoperable platforms that assemble morphological, ecological and trophic data as traits of soil taxa will enable the refinement and expansion of the multifunctional classification of consumers in soil. The compiled multifunctional classification of soil-associated consumers will serve as a reference for ecologists working with biodiversity changes and biodiversity-ecosystem functioning relationships, making soil food-web research more accessible and reproducible., (© 2022 The Authors.

- Abstract
The mesovoid shallow substratum (MSS) can act as a climatic refuge for invertebrates, as a biogeographic corridor to deeper substrates or as a permanent habitat for some species. This study characterizes the seasonal invertebrate diversity and abundance of MSS ecosystems in central Portugal focusing on Diplopoda, Diplura, Orthoptera and Coleoptera during one year. Sampling was performed with standard MSS pitfalls in scree slopes (colluvial MSS) of karst areas and environmental parameters (temperature, pH, conductivity, water content, organic carbon, nitrate, phosphate and ammonium) were quantified. Our results show that winter was the season with the highest arthropod abundance and that the MSS acts as a permanent habitat for chordeumatidan millipedes and as a climatic refuge for orthopterans and most beetles. All Diplura collected belong to a single species known previously from surface habitats in the Iberian Peninsula, which does not seem to use the Portuguese MSS as a refuge. MSS habitats in central Portugal, classified as western Mediterranean and thermophile deposits protected by the Natura 2000 network based on plant communities and geology, revealed an abundant and diverse invertebrate community that urges characterization and protection., (Copyright © 2021 Elsevier GmbH.

- Abstract
The number of citations a peer-reviewed article receives is often used as a measure of its importance and scientific impact. This paper identifies, describes and categorizes the highly cited papers in addiction research on cannabis, heroin, cocaine and psychostimulants. Highly cited papers were identified in the Web of Science Core Collection database. Several bibliometric indicators were calculated. Social network analysis was applied to draw groups of authors and institutions with the greatest number of collaborations and co-words. The number of citations for the top 100 cited articles ranged from 649 to 4,672. The articles were published in 40 journals. The subject category Substance Abuse included 10 papers. The United States was the most productive country (79 papers), followed by the United Kingdom (9). The main funding institutions were the National Institutes of Health in the United States. The network of collaboration between authors distributes the 352 researchers into 53 groups. The three most cited works address the neural basis of drug craving as an incentive-sensitization theory of addiction, the clinical and research uses of the Addiction Severity Index, and the neurocircuitry of addiction. Scientific literature on addictions is widely dispersed both in multidisciplinary and specific journals of neurology, psychiatry and addictions, with relatively few publications providing most of the citations. An ongoing challenge for this field is the concentration of highly cited papers coming from a select number of countries, with the United States being the research hub of the world, with the highest volume of publications and total citations., (Copyright © 2021.

- Abstract
A description is given of a biogeographically interesting new species of Campodeidae (Diplura), Plusiocampa (Plusiocampa) tinoamorei sp. nov., a troglobiotic species found in the Sicilian Villasmundo and Scrivilleri caves. A second subterranean species already known from three caves in northwest Sicily near Palermo, Campodea (Campodea) majorica sicula Condé, 1957, also was studied. Both species were characterized with SEM. Each species belongs to a different monophyletic group: Plusiocampa s. str., with thoracic medial posterior macrosetae, and the group related to Campodea (Campodea) grassi Silvestri, 1912. Both groups are widely distributed on almost all of the large western Mediterranean islands. Nevertheless, although these two monophyletic groups have a different origin both could be dispersed via land connections between the mainland and the islands during the Messinian Age. This new discovery shows the great value of Sicilian caves that hold species with unique features and of high biogeographic significance.

15. Energy and speleogenesis: Key determinants of terrestrial species richness in caves.

- Abstract
The aim of this study was to unravel the relative role played by speleogenesis (i.e., the process in which a cave is formed), landscape-scale variables, and geophysical factors in the determination of species richness in caves. Biological inventories from 21 caves located in the southeastern Iberian Peninsula along with partial least square (PLS) regression analysis were used to assess the relative importance of the different explanatory variables. The caves were grouped according to the similarity in their species composition; the effect that spatial distance could have on similarity was also studied using correlation between matrices. The energy and speleogenesis of caves accounted for 44.3% of the variation in species richness. The trophic level of each cave was the most significant factor in PLS regression analysis, and epigenic caves (i.e., those formed by the action of percolating water) had significantly more species than hypogenic ones (i.e., those formed by the action of upward flows in confined aquifers). Dissimilarity among the caves was very high (multiple-site β
sim = 0.92). Two main groups of caves were revealed through the cluster analysis, one formed by the western caves and the other by the eastern ones. The significant-but low-correlation found between faunistic dissimilarity and geographical distance ( r = .16) disappeared once the caves were split into the two groups. The extreme beta-diversity suggests a very low connection among the caves and/or a very low dispersal capacity of the species. In the region under study, two main factors are intimately related to the richness of terrestrial subterranean species in caves: the amount of organic material (trophic level) and the formation process (genesis). This is the first time that the history of a cave genesis has been quantitatively considered to assess its importance in explaining richness patterns in comparison with other factors more widely recognized.- Published
