Exploring the importance of innovation ambidexterity on performance: insights from NCA and IPMA analysis
No full textVersión aceptada de artículo publicado en: International Journal of Innovation Science. https://doi.org/10.1108/IJIS-03-2024-0075OBJETIVO - La agroindustria muestra un creciente grado de competitividad e innovación. Sin embargo, los mecanismos organizativos que compiten por la innovación y el rendimiento organizativo no están suficientemente estudiados. Así pues, este estudio pretende analizar la influencia de la orientación al mercado y la estructura organizativa en la innovación generada y su influencia en el rendimiento comercial y financiero de las empresas agroalimentarias de Extremadura (España). DISEÑO/METODOLOGÍA/ENFOQUE - Se diseñó y probó un modelo conceptual. Los datos se recogieron a partir de un cuestionario enviado a empresas agroalimentarias innovadoras. El análisis del modelo combina metodológicamente la modelización de ecuaciones estructurales por mínimos cuadrados parciales (PLS-SEM), el análisis de condiciones necesarias (NCA) y el análisis de mapas de importancia-rendimiento (IPMA). CONCLUSIONES - Los principales resultados revelan que los bajos niveles de ambidexteridad innovadora repercuten significativamente en el rendimiento, pero en comparación con la innovación de explotación, la innovación de exploración muestra una mayor influencia en el rendimiento financiero y de mercado. IMPLICACIONES PRÁCTICAS - Los resultados pretenden ser útiles a los directivos para mejorar su rendimiento innovador mediante la incorporación de nuevas estrategias en la orientación al mercado y la estructura organizativa. ORIGINALIDAD/VALOR - La originalidad de esta investigación radica en la novedad de los mediadores propuestos, así como del sector objeto de estudio. El estudio amplía el conocimiento de la influencia que la orientación al mercado y la estructura organizativa tienen sobre los tipos de innovación (radical/incremental).PURPOSE – Agribusiness shows a growing degree of competitiveness and innovation. However, the organizational mechanisms that compete for innovation and organizational performance are not sufficiently studied. Thus, this study aims to analyze the influence of market orientation and organizational structure on innovation generated and its influence on market and financial performance in agribusiness firms in Extremadura (Spain). DESIGN/METHODOLOGY/APPROACH – A conceptual model was designed and tested. Data were collected from a questionnaire sent to innovative agri-food companies. The analysis of the model methodologically combines partial least square structural equation modelling, necessary condition analysis and importance-performance map analysis. FINDINGS – The main results reveal that low levels of innovation ambidexterity impact significantly performance but when compared to exploitative innovation, explorative innovation shows a stronger influence on the market and financial performance. PRACTICAL IMPLICATIONS – The results are intended to be useful to managers to improve their innovative performance by incorporating new strategies in the market orientation and organizational structure. ORIGINALITY/VALUE – The originality of this research lies in the novelty of the proposed mediators, as well as the sector under study. The study expands the knowledge of the influence that market orientation and organizational structure have on the types of innovation (exploitative/explorative).This research was supported by the Junta de Extremadura (Spain)/European Regional Development Fund [grant number IB18040] and the Fundação para a Ciência e a Tecnologia [grant UIDB/00315/2020].peerReviewe
Autopercepción de la calidad del sueño durante la pandemia de COVID-19: Factores de riesgo y protección
No full textLa situación derivada de la enfermedad por Coronavirus (COVID-19) y los sucesivos confinamientos ordenados para controlar la pandemia llevaron a problemas sin precedentes en diferentes aspectos del bienestar de las personas. Este estudio tuvo como objetivo explorar los efectos agudos del primer confinamiento en la calidad del sueño autopercibida, así como los factores de riesgo y protectores que pueden modular este impacto. La muestra estuvo compuesta por 1,275 encuestados con edades entre 18 y 55 años. Los participantes fueron reclutados durante el primer confinamiento por COVID-19 en España. Se les evaluó en relación con sus problemas de sueño autoinformados antes y durante el confinamiento, así como en otras áreas relacionadas con el impacto del confinamiento (por ejemplo, en la dieta, la actividad física o el uso de medios digitales), estados psicológicos (afecto positivo y negativo) y rasgos (impulsividad). La mayoría de los participantes (66.7%) informaron de una disminución en la calidad del sueño percibida durante la pandemia. Los análisis correlacionales mostraron que mantener buenos niveles de actividad física y calidad de la dieta durante la pandemia estaban positivamente asociados con la calidad del sueño; además, niveles mayores de afecto positivo, vivir en hogares más grandes durante el confinamiento y la edad también estaban positivamente asociados con la calidad del sueño.
Por el contrario, el afecto negativo, el ser mujer y el impacto de la pandemia en varios dominios (salud mental, calidad de las relaciones, finanzas personales y el uso de medios digitales) estaban negativamente relacionados con la calidad del sueño percibida. Así pues, esta investigación sustenta el impacto de la pandemia de COVID-19 en la calidad del sueño percibida y proporciona una base preliminar para identificar factores protectores y de riesgo que contribuyen a la calidad del sueño durante el confinamiento y otras situaciones de estrés.The situation derived from the Coronavirus disease (COVID-19) and lockdowns ordered to control the pandemic led to unprecedented problems in different areas of people’s well-being. This study aimed to explore the acute effects of the first lockdown on self-perceived sleep quality, as well as the risk/protective factors that modulated this impact. The sample was composed by 1,275 respondents ranging in age from 18 to 55 years. Participants were recruited during the COVID-19 first lockdown in Spain. They were evaluated regarding their selfreported sleep problems before and during lockdown, as well as other areas related to the impact of lockdown (e.g., on diet, physical activity, or use of digital media), psychological states (positive and negative affect), and traits (impulsivity). Most participants (66.7%) reported a decrease in their self-perceived sleep quality during the pandemic. Correlational analyses showed that maintaining good levels of physical activity and diet quality during the pandemic were positively associated with sleep quality; furthermore, greater levels of positive affect, living in bigger homes during lockdown, and age were positively associated with sleep quality as well.
On the contrary, negative affect, female sex, and the impact of the pandemic on various domains (mental health, relationship quality, personal finances, and the use of digital media) were negatively related to self-perceived sleep quality. In brief, this study supports the impact of the COVID-19 pandemic on self-perceived sleep quality and provides a preliminary foundation for identifying protective and risk factors contributing to sleep quality during lockdowns and other situations of distress.peerReviewe
Internet interventions and therapies for addressing the negative impact of digital overuse: a focus on digital free tourism and economic sustainability
No full textThe excessive use of information technologies (IT) and online digital devices are causing symptoms of burnout, anxiety, stress and dependency that affect the physical and mental health of our society, extending to leisure time and work relationships. Digital free tourism (DFT) is a phenomenon that emerges as a solution to technostress and pathologies derived from digital hyperconnection. The objective of this research is to advance the knowledge of new structures of motivational factors that can understand the decision of a tourist to make a DFT trip. To this end, it is investigated whether family and social engagement and health and relaxation have a positive impact on the behavioral intention of the potential tourist and whether this influences sustainability due to the importance of DFT in the new economic framework.
Methods With a quantitative approach, the methodology used consisted of an online questionnaire among
potential travelers. IBM SPSS Statistics 22.0 statistical software was used to evaluate the data obtained and confirm the relationships of the model and the research hypotheses.
Results The results of the questionnaire assessed the contribution of each construct to the tourist’s behavioral
intention and the tourist’s decision to make the decision to undertake a DFT experience.
Conclusions DFT can be a driver of economic sustainability and health therapy in tourism in the digital age. This
study aims to expand the lines of research on DFT and determine the complex factors that can lead a tourist to
participate in the DFT experience. The results obtained can help managers of companies in the sector to offer more efficient and sustainable services that contribute to the health and wellbeing of tourists as a differentiating factor.peerReviewe

No full textEl presente estudio pretende determinar el efecto mediador que el liderazgo auténtico del entrenador tiene sobre la interacción entre la competencia del entrenador y el apoyo percibido por los deportistas a las necesidades psicológicas básicas (NPB). Se realizó un estudio transversal con 115 jugadores de deportes de equipo (17,96 ±2,85 años; 8,18 ±4,67 años de experiencia) midiendo el Apoyo a las Necesidades Psicológicas Básicas, Liderazgo Auténtico Percibido y Percepciones de los Atletas sobre la Competencia del Entrenador. Se realizaron análisis de correlación y mediación (Competencia del entrenador → Liderazgo auténtico → Apoyo de las NPB). Se observó un efecto indirecto positivo y significativo (ƥ = 0,288; IC 95% = 0,167, 0,415) del liderazgo auténtico sobre la interacción entre la competencia del entrenador y el apoyo a las NPB (ƥ = 0,277; p < 0,01), aumentando el efecto total del modelo (ƥ = 0,555; p < 0,01) reforzando el apoyo a las NPB percibido por los deportistas cuando sus entrenadores son líderes competentes y auténticos. En conclusión, no basta con ser un entrenador bien preparado, también debe tener la capacidad de liderar, motivar y tomar decisiones cuidando sus interrelaciones con los deportistas y promoviendo la satisfacción de las necesidades psicológicas básicas.The present study aims to determine the mediating effect that authentic coach leadership has on the interaction between coach competence and athletes' perceived support for basic psychological needs (BPN). A cross-sectional study was conducted with 115 team sports players (17.96 ±2.85 years of age; 8.18 ±4.67 years of experience) using the Basic Psychological Needs Support, Perceived Authentic Leadership, and Athletes' Perceptions of Coach Competence questionnaires. Correlation and mediation analyses (Coach Competence → Authentic Leadership → BPN Support) were performed. The results show a positive and significant indirect effect (ƥ = 0.288; 95% CI = 0.167, 0.415) of authentic leadership on the direct interaction between coach competence and BPN support (ƥ = 0.277; p < 0.01), increasing the total model effect (ƥ = 0.555; p < 0.01) to aid athletes' perceived BPN support when their coaches are competent and authentic leaders. In conclusion, it is not enough to be a wellprepared coach, he/she must also have the ability to lead, motivate and make decisions taking care of his/her interrelationships with athletes and promoting the satisfaction of basic psychological needs.O presente estudo tem como objetivo determinar o efeito mediador que a liderança autêntica do treinador tem na interação entre a competência do treinador e o apoio percebido pelos atletas às necessidades psicológicas básicas (NPB). Foi realizado um estudo transversal com 115 atletas de desportos colectivos (17,96 ±2,85 anos de idade; 8,18 ±4,67 anos de experiência), utilizando os questionários Suporte das Necessidades Psicológicas Básicas, Liderança Autêntica Percebida e Percepções dos Atletas sobre a Competência do Treinador. Foram efectuadas análises de correlação e mediação (Competência do Treinador → Liderança Autêntica → Suporte das NPB). Os resultados mostram um efeito indireto positivo e significativo (ƥ = 0 ,288; 95% CI = 0,167, 0,415) da liderança autêntica na interação direta entre a competência do treinador e o apoio das NPB (ƥ = 0,277; p < 0,01), aumentando o efeito total do modelo (ƥ = 0,555; p < 0,01) para ajudar os atletas a perceber o apoio das NPB quando os seus treinadores são competentes e líderes autênticos. Concluindo, não basta ser um treinador bem preparado, é preciso também ter a capacidade de liderar, motivar e tomar decisões cuidando das suas inter-relações com os atletas e promovendo a satisfação das necesidades psicológicas básicas.peerReviewe
Dilemas de gramática española
No full textPrólogo y edición de José Carlos Martín CamachoEl libro es una compilación de trabajos previamente publicados por el autor en diversos lugares. Esta compilación puede leerse tanto de forma unitaria, porque se basa en planteamientos teóricos que impregnan todo lo tratado, como tomando cada capítulo como un estudio independiente y autosuficiente.
La importancia de publicar este libro radica en dos hechos:
a) Por un lado, permite tener acceso a publicaciones del autor que no siempre son fáciles de localizar.
b) Por otro lado, y sobre todo, constituye una obra que aborda con brillantez y maestría complejos problemas de gramática española desde una perspectiva teórica personal sólida y perfectamente fundamentada, por lo que puede resultar muy interesante para investigadores en gramática española y lingüística general, profesores de estas mismas áreas de cualquier nivel educativo y alumnos universitarios de Filología Hispánica, Filología Románica y Lingüística General.The book is a compilation of works previously published by the author in various places. This compilation can be read both in a unitary way, because it is based on theoretical approaches that permeate everything discussed, and by taking each chapter as an independent and self-sufficient study.
The importance of publishing this book lies in two facts:
a) On the one hand, it allows access to the author's publications that are not always easy to locate.
b) On the other hand, and above all, it constitutes a work that brilliantly and masterfully addresses complex problems of Spanish grammar from a solid and perfectly founded personal theoretical perspective, which is why it can be very interesting for researchers in Spanish grammar and general linguistics. teachers of these same areas of any educational level and university students of Hispanic Philology, Romance Philology and General Linguistics.peerReviewe
Gibraltar and its fit in the European Union
No full textGibraltar es un enclave estratégico situado en el extremo sur de la Península Ibérica, colindante con el Reino de España. Cedido a Reino Unido en el año 1713, el territorio ha sido y sigue siendo objeto de disputa territorial entre Reino Unido y España y un punto de tensión en sus relaciones diplomáticas por los conflictos de diversa índole que genera la zona, además del difícil contexto del territorio dentro de la Unión Europea. Sin olvidarnos que a lo largo del presente trabajo trataremos cuestiones tales como la transformación de la economía gibraltareña y su impacto sobre la zona, así como el encaje jurídico-económico que Gibraltar tiene dentro de la Unión Europea y la particularidad a la hora de la aplicación del Derecho de la Unión Europea.Gibraltar is a strategic enclave located at the southernmost end of the Iberian Peninsula, adjacent to the Kingdom of Spain. Ceded to the United Kingdom in 1713, the territory has been and continues being the subject of a territorial dispute between the United Kingdom and Spain and a major conflict for diplomatic relations due to a variety of conflicts generated by the area, in addition to the difficult context of the Territory within the European Union. Without forgetting that throughout this work we will deal with issues such as the transformation of the Gibraltarian economy and its impact on the area as well as the legal-economic fit that Gibraltar has within the European Union and the particularity at the time of the application of the Law of the European Union.peerReviewe

Exploring Trichoderma diversity for sustainable disease management in “Lolium perenne” against “Fusarium avenaceum”
No full textFinanciación Open Access proporcionada gracias al acuerdo CRUE-CSIC con Springer Nature“Fusarium” species represent a significant threat to pasture health, necessitating the development of sustainable solutions. This study explores the potential of regionally adapted “Trichoderma” isolates for controlling “Fusarium avenaceum” and promoting plant growth in the grasslands of the Iberian Peninsula. To this end, seven “Trichoderma” isolates (belonging to “T. koningiopsis”, “T. koningii” and “T. gamsii”) were obtained from soils of Extremadura and then evaluated as potential biocontrol agents against “Fusarium avenaceum”. For the purposes of this evaluation, water was used as a negative control, while a commercial “Trichoderma” product served as a positive control. An initial in vitro evaluation revealed that six “Trichoderma” isolates significantly inhibited “F. avenaceum” in a dual culture assay, reducing pathogen growth by 18 to 49%. Additionally, two of the isolates showed antifungal potential during the evaluation of their culture filtrates. Subsequently, two greenhouse assays were conducted to assess the effects of “Trichoderma" isolates and the pathogen on the development of “Lolium perenne”. One focused on seed germination and the other on established plants. The greenhouse experiments indicated that T08 (“T. koningiopsis”), T14 (“T. koningii”), and T19 (“T. gamsii”) significantly improved seed germination and plant growth, even outperforming the positive control on total dry matter in pathogen-infected plants during the postemergence test. Our study highlights the potential of “Trichoderma” isolates, particularly T08, T14, and T19, to boost plant growth and control “Fusarium avenaceum” in “Lolium perenne”. It emphasizes the importance of in planta testing and reveals the varying effects of the isolates throughout the plant cycle.Carlos Moraga has been financed by a pre-doctoral grant (PRE2021-100318) funded by MICIU/AEI/10.13039/501100011033 and by “ESF Investing in your future”.peerReviewe

Grammatical gender in Spanish: history of a concept
No full textEl objetivo de este trabajo es analizar la evolución del concepto género gramatical en español desde una perspectiva lexicográfica. Partiendo de la idea de que el género en español ayuda a expresar relaciones de concordancia con determinantes y otras clases de palabras que acompañan al sustantivo en el grupo nominal, trataremos de comprender cómo se produjo el paso del vocablo latino GENUS, GENERIS al castellano género, en una trasposición conceptual que, para explicar el vocablo desde el punto de vista semántico, ha tenido siempre en cuenta sus relaciones con el concepto sexo (biológico). Esta visión aflora en los primeros diccionarios de la lengua que conceden al género una especialización gramatical de uso y llegan hasta la última edición del repertorio académico, la 23.ª, de 2014. Mediante el análisis de las definiciones que ofrecen los diccionarios del español, y con el apoyo de algunas de sus gramáticas, se intentará demostrar que el uso del sustantivo género con sentido gramatical es tardío en los glosarios de nuestra lengua y que, desde los primeros registros, no logró desprenderse de sus primitivas acepciones, más próximas a los conceptos ‘clase’, ‘tipo’, ‘especie’, ‘categoría’ (habituales desde Nebrija) de los que también derivó el que nos ocupa. Porque, como muestran los diccionarios, esta acepción surgió para clasificar la categoría del nombre según el sexo del referente o para establecer relaciones sintácticas de concordancia con otras clases de palabras, sin olvidar su carácter morfemático en sustantivos que designan especies con función procreadora.The aim of this paper is to analyze the evolution of the concept of grammatical gender in Spanish from a lexicographical perspective. Starting from the idea that gender in Spanish helps to express agreement relationships with determiners and other kinds of words that accompany the noun in the nominal group, I will try to understand how the Latin word GENUS, GENERIS developed into Castilian género ‘gender’. It concerns a conceptual transposition that for the explanation of the word from a semantic point of view, has always taken into account its relationship with the (biological) concept of sex. This view emerges in the first language dictionaries, which allow for a grammatical specialization of the use of género, and persists until the latest, 23rd, edition of the academic dictionary, from 2014. Through the analysis of the definitions offered by the Spanish dictionaries, and with the support of some grammars, I will try to show that the use of the noun género with a grammatical meaning appears late in the wordlists of our language and that, from the first records onward, it has never been detached from its primitive meanings, closer to the concepts 'class', 'type', 'species', 'category' (common since Nebrija) from which the one of interest here also derived. Because, as the dictionaries show, this meaning arose to classify the category of the noun according to the sex of its referent or to establish syntactic relationships of agreement with other classes of words, without ever losing its morphematic character in nouns that designate species with a procreative function.peerReviewe
