RadioWeb: herramienta Web para la realización de prácticas de asignaturas relacionadas con sistemas de radiocomunicaciones.
[SPA]La creciente expansión de sistemas de comunicaciones inalámbricas ha supuesto la inclusión, en los planes de
estudios de carreras técnicas, de asignaturas, en las que se estudia y analiza, tanto a nivel teórico como práctico, la
planificación de estos sistemas desde el punto de vista radioeléctrico.
El número elevado de sistemas de radiocomunicaciones (telefonía móvil, televisión y radio digital, redes
inalámbricas, etc., cada uno de ellos con sus particularidades desde el punto de vista radioeléctrico) ha hecho necesaria
para su planificación la utilización de herramientas informáticas basadas en sistemas de información geográfica (SIG),
puesto que se trata de un problema espacial (localización de emplazamientos, entornos de propagación) en el que se
maneja también abundante información descriptiva (coordenadas del emplazamiento, parámetros radioeléctricos de los
equipos, sistemas radiantes, etc.).
Estas herramientas funcionan en modo local y, por tanto, el SIG sobre el que está desarrollado la aplicación,
debe estar instalado en cada puesto de laboratorio en el que se vayan a realizar las prácticas correspondientes. En este
trabajo, se presenta la herramienta RADIOWEB basada en ArcGIS Server de ESRI, que permite realizar vía web
prácticas relacionadas con la planificación de sistemas de radiocomunicaciones, teniendo aplicación, por tanto, en un
contexto de enseñanza-aprendizaje basado en e-learning. [ENG]The constant evolution of the wireless communication systems has involved the inclusion, in the syllabus of
technical degrees, of subjects in which the planning of such systems is studied and analyzed −from a radioelectric point
of view− both at a theoretical level and at a practical level.
The large number of radiocommunication systems (mobile phones, television and digital radio, wireless
networks, etc), each of them with its special features from a radioelectric point of view, has resulted in the need of the
use of computing tools based on Geographic Information Systems (GIS) for the planning of the above-mentioned
radiocommunication systems, since the latter is a spatial issue (sites location, propagation environments) in which
plenty of descriptive information is also managed (site coordinates, equipment radioelectric parameters, radiant
systems, etc.).
These tools work in local mode and, therefore, the GIS software that supports the developed application must
be installed in each laboratory workstation in which the corresponding laboratory session is going to be performed. . In
this work, the computing tool RADIOWEB, which is based on ArcGIS Server from ESRI, is presented. This tool
permits the performance of laboratory sessions related to radiocommunication systems planning via web and, in this
sense, it can be applied in a teaching-learning context based on e-learning.Campus Mare Nostrum, Universidad Politécnica de Cartagena, Universidad de Murcia, Región de Murci

Відмінності у перфекціонізмі та захопленні між напівпрофесійними футболістами віком до 21 та до 23 років
Study purpose. The aim of this study is to analyse differences in perfectionism and passion and how these variables interact and might be expected to affect performance in U21 and U23 soccer players.
Materials and methods. A total of 60 healthy semi-professional soccer players (age: 21.57±1.95 years; height: 179.76±5.79 cm) participated in the study. The participants were divided into two equal groups, one with those players younger than 21 years old and the other including players aged 21–23. This study was descriptive with a cross-sectional design and used the Frost Multidimensional Perfectionism Scale (FMPS) and Passion Scale questionnaires.
Results. A paired-samples t-test was used for defining differences as a repeated measures analysis (U21 Group and U23 Group). Additionally, a t-test with data from the FMPS revealed significant differences in perfectionism global score, concern over mistakes, parental expectations, parental criticism, doubts about actions and organization. The participants were shown to be a heterogeneous group in both perfectionism and passion, with moderate perfectionistic characteristics, except for the personal standards subscale, in which the opposite trend was found. According to the outcomes obtained, the U21 group shows significant values in terms of the level of perfectionism.
Conclusions. This research has highlighted the importance of addressing maladaptive perfectionism in interventions and support programs for athletes. Strategies such as promoting a growth mindset, encouraging self-compassion, and fostering a supportive and mastery-oriented environment have been suggested to help athletes manage perfectionistic tendencies and enhance their well-being and performance.Мета дослідження. Мета цього дослідження полягає в тому, щоб проаналізувати відмінності в перфекціонізмі та захопленні, а також те, як ці змінні взаємодіють і можуть впливати на результативність у футболістів віком до 21 та до 23 років.
Матеріали та методи. Загалом у дослідженні взяли участь 60 здорових напівпрофесійних футболістів (вік: 21,57±1,95 року; зріст: 179,76±5,79 см). Учасників розподілили на дві рівні групи: одну з гравцями молодше 21 року, а другу з гравцями віком 21–23 роки. Це дослідження було описовим із перехресним планом дослідження, і в ньому використовували опитувальники «Багатовимірна шкала перфекціонізму Фроста» (FMPS) та «Шкала захоплення».
Результати. Для визначення відмінностей використовували t-критерій Стьюдента для парних вибірок як аналіз повторних вимірювань (група віком до 21 року та група віком до 23 років). Крім того, завдяки застосуванню t-критерію Стьюдента з даними опитувальника FMPS були виявлені статистично значущі відмінності в загальній оцінці рівня перфекціонізму, стурбованості щодо помилок, батьківських очікуваннях, батьківській критиці, сумнівах щодо дій та організації. Було показано, що учасники являють собою гетерогенну групу як за перфекціонізмом, так і за захопленням, із помірними перфекціоністськими характеристиками, за винятком підшкали особистих стандартів, у якій спостерігається протилежна тенденція. Відповідно до отриманих результатів, група віком до 21 року демонструє значні величини рівня перфекціонізму.
Висновки. Це дослідження підкреслило важливість усунення неадаптивного перфекціонізму у втручаннях і програмах підтримки для спортсменів. Були запропоновані такі стратегії, як сприяння психології зростання, заохочення співчуття до себе та сприяння розвитку сприятливого й орієнтованого на майстерність середовища, щоб допомогти спортсменам керувати перфекціоністськими тенденціями та покращувати своє самопочуття та результативність
Assessing the levels of intraspecific admixture and interspecific hybridization in Iberian wild goats (Capra pyrenaica)
Iberian wild goats (Capra pyrenaica, also known as Iberian ibex, Spanish ibex, and Spanish wild goat) underwent strong genetic bottlenecks during the 19th and 20th centuries due to overhunting and habitat destruction. From the 1970s to 1990s, augmentation translocations were frequently carried out to restock Iberian wild goat populations (very often with hunting purposes), but they were not systematically planned or recorded. On the other hand, recent data suggest the occurrence of hybridization events between Iberian wild goats and domestic goats (Capra hircus). Augmentation translocations and interspecific hybridization might have contributed to increase the diversity of Iberian wild goats. With the aim of investigating this issue, we have genotyped 118 Iberian wild goats from Tortosa-Beceite, Sierra Nevada, Muela de Cortes, Gredos, Batuecas and, Ordesa and Monte Perdido by using the Goat SNP50 BeadChip (Illumina). The analysis of genotypic data indicated that Iberian wild goat populations are strongly differentiated and display low diversity. Only three Iberian wild goats out from 118 show genomic signatures of mixed ancestry, a result consistent with a scenario in which past augmentation translocations have had a limited impact on the diversity of Iberian wild goats. Besides, we have detected eight Iberian wild goats from Tortosa-Beceite with signs of domestic goat introgression. Although rare, hybridization with domestic goats could become a potential threat to the genetic integrity of Iberian wild goats, hence measures should be taken to avoid the presence of uncontrolled herds of domestic or feral goats in mountainous areas inhabited by this iconic wild ungulate.Publishe
Desarrollo de una herramienta de cálculo de cobertura radioeléctrica vía Web basada en el sistema de información geográfica ArcGIS Server
En este artículo se presenta uno de los proyectos en los que está trabajando el Grupo de Sistemas de Comunicaciones Móviles (SiCoMo) junto con la empresa Radiatio Ingeniería: el desarrollo de una herramienta de cálculo de cobertura vía Web. El creciente despliegue de sistemas de radiocomunicaciones de telefonía móvil (GSM, UMTS, TETRA, LTE, Wimax, etc.), televisión digital terrestre, radio digital, redes inalámbricas como WiFi, redes punto-multipunto como LMDS o MMDS, hace necesario disponer de herramientas informáticas [1] para el cálculo de cobertura radioeléctrica (pieza clave en la planificación y optimización de dichos sistemas). Dichas herramientas informáticas suelen estar basadas en sistemas de información geográfica (SIG) [2] y funcionan en modo local, pero puede resultar de gran interés disponer de un servicio de cálculo de cobertura víaWeb que tendría aplicación tanto en el mundo empresarial como en el educativo (e-learning). En este artículo se expondrán los fundamentos y objetivos principales que se persiguen. Se presentará una herramienta para la planificación radioeléctrica vía Web, describiendo su arquitectura, funcionalidades y funcionamiento.Incorporación de titulados a las actividades de I+D+I Empresariales de la Consejería de Universidades, Empresa e Investigación de la CARM (ref. 2I10IE0030)
