Sustainable tourist route among the medieval coastal towers of the Mar Menor
Get PDFOn the coast of South-Eastern Spain, in the Mar Menor area, a tourist route is proposed that begins and ends at two coastal towers that in the 16th century were used to defend the population that settled in the coastal area against Berber attacks from North Africa. This route, designed for cycling or walking, would be about 10 km long, starting at the Negro Tower, going towards the sea, visiting a mountain of volcanic origin and continuing through a natural wetland parallel to the Mar Menor of great natural value and ending at the Rame Tower. Along this tour, there are around twenty points of interest, which include architectural elements, such as windmills, historical elements, such as ancient Roman metallurgical sites, but also natural elements of interest such as unique flora and fauna, geological formations of interest and points with different types of soil. The digital reconstruction of the Negro Tower and the Rame Tower has been carried out, proposing flexible uses for both residents and tourists, making a meeting place for both. The intervention of both towers is a key and fundamental issue to avoid their loss. In the case of the Negro Tower, an integral rehabilitation is proposed, considering the vertical communication between floors, the construction of the vault of the first and first floors and the staircase between them to reach the walkable roof and an external staircase for access to the first floor. Also acting on the surrounding land by establishing rest areas, information areas with information panels on the history of the building and its various uses over the last five centuries and a car park for bicycles that want to make the route. In the case of the Rame Tower, a BIM of the tower has been created so that it can accompany the building in its management and maintenance for the rest of its life, and the rehabilitation of an adjoining house has also been designed to serve as a cafeteria for both residents and tourists following the route. A space for local economic development and local crafts is generated to promote responsible tourism
Does female executives’ involvement in corruption affect firm value? European evidence
No full textThe contentious literature concerning the relation between corporate corruption and firm performance suggests a potential avenue for research to examine the influence of gender on corruption. Two-stage least squares estimations performed on a sample of EU countries reveal a robust negative association between female corrupt executives and firm value. Our findings signal that firms led by corrupt female executives tend to have a more detrimental impact on firm value compared to those led by corrupt male executives. This study represents the inaugural attempt to investigate the magnitude of women's involvement in corruption, with results supporting the notion of corruption's detrimental impact on firm value evidencing a 'sand-the-wheel' effect. Our research is significant in that it uses firm-specific data to gain a deeper understanding of the issue of corporate fraud and the involvement of women. Theoretical and managerial implications as well as suggestions for future research regarding the role of women in management are outlined in the conclusion section of this chapter
Sustainable logistics: study of population mobility patterns in an urban centre
Get PDFActualmente, se atraviesa una época donde todo es cada vez más exigente y complicado: las ciudades se expanden; aumenta la preocupación por el medio ambiente; y el comercio electrónico y el transporte de mercancías toma una mayor relevancia. En los núcleos urbanos con frecuencia se olvida que el ciudadano generalmente se desplaza a pie, dando sentido al espacio público, donde pasear, relacionarse, comprar, conocer, divertirse, trabajar, etc. En conclusión, realiza una infinidad de actividades que se deberían fomentar y para ello brindar de los espacios adecuados. Los motivos de analizar la movilidad de los ciudadanos en el entorno urbano, tiene su origen en la confrontación del peatón con los vehículos motorizados. Teniendo en cuenta las directrices europeas sobre ciudades sostenibles, es frecuente observar como las administraciones locales, con miras de conseguir ciudades más saludables para sus usuarios, están peatonalizando numerosas calles en los centros urbanos. Si bien, estas medidas no solo tienen como consecuencia inmediata la reducción de emisiones en dichas zonas, sino que además se consigue potenciar el comercio y la oferta cultural de la zona. Pero da lugar a la aparición de problemas como pueden ser las nuevas limitaciones de estacionamiento, dificultando el fácil acceso de los vecinos, trabajadores y usuarios a estas áreas. Todos estos hechos afectan a la actividad diaria del núcleo urbano, tanto en el ámbito laboral, comercial, sanitario, entre otros. Por tanto, la sociedad se encuentra con un nuevo problema a solventar derivado de todo lo anterior, por lo que debe aparecer algo que pueda resolver de una forma eficaz y sostenible con el medio ambiente a la vez que ajustado a las normativas vigentes la creciente problemática urbana. Es en este punto donde aparece/surge la denominada “logística sostenible”. En resumen, el presente trabajo surge de la necesidad de caracterizar cómo se mueven los ciudadanos en un pequeño núcleo urbano según su actividad diaria, estudiar sus preferencias de movilidad y analizar su actitud hacia la caminabilidad. Con el fin último de dar respuesta a las consecuencias que esto tendrá sobre la sociedad y sobre la logística urbana de la zona.Escuela Técnica Superior de Ingeniería IndustrialUniversidad Politécnica de Cartagen

Geospatial feature-based path loss prediction at 1800 MHz in covenant university campus with tree ensembles, kernel-based methods, and a shallow neural network
Get PDFThis paper investigates within-scene path loss prediction at 1.8 GHz in a smart-campus micro-urban environment using multivariate machine-learning (ML) models. We leverage an open measurement campaign from Covenant University (Nigeria) comprising three routes with per-sample geospatial predictors—longitude, latitude, altitude, elevation, Tx–Rx distance, and clutter height—and train Random Forests (RF), Gradient Boosting (GB), Support Vector Regression (SVR), Gaussian Processes (GP), and a shallow neural network (NN). A unified pipeline with 5-fold cross-validation (CV), seeded reproducibility, and Optuna-driven hyperparameter search is adopted; performance is reported as RMSE/MAE/R2 (mean ± sd). To contextualize feature reliability, we include Pearson correlation heatmaps and Variance Inflation Factors (VIFs), a systematic ablation of predictors, and TreeSHAP beeswarm analyses on held-out splits. We also evaluate spatially aware validation (blocked CV within route and leave-one-route-out checks) to mitigate optimism due to spatial autocorrelation. Results show that multivariate ML consistently outperforms classical empirical formulas (COST-231, ECC-33) in this campus setting, with RF achieving the lowest errors across routes (RMSE ≈ 2.14/2.16/2.95 dB for X/Y/Z, respectively), while GB ranks second and kernel methods (SVR/GP) and the NN trail closely behind. Ablation confirms that distance plus coordinates drive the largest gains, with terrain/clutter providing route-dependent refinements. SHAP analyses align with these findings, highlighting stable, interpretable contributions of geospatial covariates. Spatial CV increases absolute errors moderately but preserves model ranking, supporting the robustness of conclusions. Overall, scenario-aware, multivariate ML yields material accuracy gains for smart-campus planning at 1.8 GHz.This work was supported by the Ministerio de Ciencia e Innovación, Spain, under Grant PID2022-136869NB-C32 funded by MCIN/AEI/10.13039/501100011033 and by the European Union.

LM-Hunter: An NLP-powered graph method for detecting adversary lateral movements in APT cyber-attacks at scale
No full textAPT (Advanced Persistent Threat) actors are highly skilled cyber attackers who employ sophisticated techniques to infiltrate and maintain unauthorized access to a network over an extended period. In the APT lifecycle, lateral movement stands out as a critical stage where intruders escalate privileges and move across the network to expand their control and access to sensitive data. While solutions such as UEBA (User and Entity Behavior Analytics) or graph analysis have been proposed to identify lateral movements, their application in real-world cybersecurity incidents remains impractical in terms of both scalability and performance. This paper introduces LM-Hunter, a new robust and efficient method for identifying stealth adversaries moving laterally through the network at scale. LM-Hunter takes advantage of graphs and Transformers, a specific architecture within NLP (Natural Language Processing), to learn the network dynamics for hunting the most suspicious lateral movements of the users. The method is validated in a real-world cybersecurity incident at a Fortune 500 company, one of the largest corporations in the United States, demonstrating its capability to identify adversarial lateral movements in large enterprise networks. LM-Hunter enhances the threat detection capabilities of Incident Response and Threat Hunting teams in real-world scenarios. The application of the method is facilitated by releasing LM-Hunter as an open-source tool, expanding the arsenal of cybersecurity teams for combating cyber threats

De una pandilla de amigos a una comunidad cristiana de base en La Palma (Cartagena)
Get PDF[SPA] A mediados de 1970, un grupo significativo de adolescentes y jóvenes de La Palma de Cartagena, entre 12 y 14 años, desarrollábamos nuestra sociabilidad en diferentes espacios como el club juvenil y la parroquia. En el club juvenil las actividades que realizábamos eran diversas: bailes, juegos de mesa, cenas, cine forum, tertulias, etc. Nos organizábamos de una manera espontánea y no teníamos una directiva ni unos estatutos que regularan el funcionamiento del grupo.El otro lugar de encuentro fue la parroquia, gracias a dos curas que estuvieron en la parroquia de La Palma entre los años 1978 y 1986, que tenían una gran habilidad para conectar con el mundo adolescente y juvenil, supieron atraer a muchos miembros de la pandilla e integrarlos en la parroquia para constituir un catecumenado juvenil, cuya meta fue la constitución de la pequeña comunidad cristiana de base de Moncada en La Palma. Ésta acaba de celebrar en 2025 su 36 aniversario. Tiene su sede en una finca situada en el paraje de Los Lorcas (Los Médicos) y fue adquirida no sólo para uso de la comunidad sino también para ponerla al servicio de todos aquellos colectivos que trabajen por los más pobres, la evangelización y la promoción humana. Como métodos de investigación hemos utilizado la entrevista, la observación y el análisis de acontecimientos vividos anteriormente y el objetivo que hemos pretendido es analizar el proceso de transformación de una pandilla a una comunidad cristiana de base en el bloque de análisis y estudio de la sociabilidad rural. [ENG] In the mid-1970s, a significant group of teenagers and young people aged between 12 and 14 years old from La Palma of Cartagena, developed their sociability in a gang. There were two fundamental meeting places: the youth club at the beginning and the parish later. The activities we carried out in the youth club were diverse: dances, board games, dinners, film forums, gatherings, etc. The group was organized in an informal way, without a leadership or statutes that regulated the functioning of the group.The other meeting place was the parish, since two priests were in charge of La Palma’s church between the years 1978 and 1986 who had a great ability to connect with the youth world, knew how to attract many members of the gang and integrate them into the parish to form a youth catechumenate and whose goal was the constitution of the small Christian base community of Moncada. It has just celebrated its 36th anniversary and is based on a farm located in the area of Los Lorcas (Los Medicos), and was bought not only for community use but also to put it at the service of all those groups that work for the poorest, evangelization and human promotion, research methods were interviews, observation, and analysis of previously experienced events. Our goal was to analyse the process of transformation from a gang to a grassroots Christian community
