THE THEORIES AND PRACTICES OF LOPE AND MORATÍN: THE NEW THEATRE AND 'THE NEW PLAY'
2021
En este artículo, por primera vez, se ponen en relación las teorías teatrales de dos dramaturgos españoles que crearon escuela: Lope de Vega y Leandro Fernández de Moratín. Dos siglos separan sus creaciones, pero ambos pretendieron renovar la escena con sus poéticas, ambos pretendieron una «nueva comedia» que rompiera con las tradiciones teatrales inmediatamente anteriores. Las obras dramáticas de uno y otro autor, en realidad se sitúan en polos opuestos en cuanto a su extensión; la de Lope abarca más de cuatrocientos títulos, mientras que Moratín apenas tiene en su haber media decena de piezas. El más fecundo e internacional poeta dramático español y el más comedido de entre los dramaturgo…
Prepulse inhibition can predict the motivational effects of cocaine in female mice exposed to maternal separation
2020
The prepulse inhibition (PPI) of the startle response can identify the rodents that are more sensitive to the effects of cocaine. Mice with a lower PPI presented a higher vulnerability to the effects of cocaine and a higher susceptibility to developing a substance use disorder (SUD). Maternal separation with early weaning (MSEW) is a relevant animal model to induce motivational alterations throughout life. Nevertheless, only a few studies on females exist, even though they are more vulnerable to stress- and cocaine-related problems. Hence, the aim of the present study was to evaluate the ability of PPI to identify females with a greater vulnerability to the long-term consequences of early s…
Stretch-shortening cycle: a powerful model to study normal and fatigued muscle.
2000
Stretch-shortening cycle (SSC) in human skeletal muscle gives unique possibilities to study normal and fatigued muscle function. The in vivo force measurement systems, buckle transducer technique and optic fiber technique, have revealed that, as compared to a pure concentric action, a non-fatiguing SSC exercise demonstrates considerable performance enhancement with increased force at a given shortening velocity. Characteristic to this phenomenon is very low EMG-activity in the concentric phase of the cycle, but a very pronounced contribution of the short-latency stretch-reflex component. This reflex contributes significantly to force generation during the transition (stretch-shortening) pha…
Preferential Type II Muscle Fiber Damage From Plyometric Exercise
2012
Context: Plyometric training has been successfully used in different sporting contexts. Studies that investigated the effect of plyometric training on muscle morphology are limited, and results are controversial with regard to which muscle fiber type is mainly affected. Objective: To analyze the skeletal muscle structural and ultrastructural change induced by an acute bout of plyometric exercise to determine which type of muscle fibers is predominantly damaged. Design: Descriptive laboratory study. Setting: Research laboratory. Patients or Other Participants: Eight healthy, untrained individuals (age = 22 ± 1 years, height = 179.2 ± 6.4 cm, weight = 78.9 ± 5.9 kg). Intervention(s): Partici…
‘That is Why I Gave In to Age My Competitive Ability, but Not My Soul!’ A Spiritual Journey in Endurance Running
2012
In this article, we explore the spiritual dimensions of endurance running. Utilizing existential psychology as our theoretical framework, we approach spirituality as a broad concept encompassing both religious and humanistic worldviews. Through the first author's reflexive narrative and a discourse analysis of a Finnish runner's magazine, Juoksija, this study aimed to gain a deeper understanding of how distance runners negotiate dominant discourses on sport and religion in the process of making running existentially meaningful to them. The research results suggest that spiritual aspects of running underlie, but are rarely given voice in, the performance discourse that is dominant in Finnish…
Participant Observation: The Personal Commitment in Native Life—A Problematic Methodological Topos
2020
While it is well known that fieldwork started long before Malinowski, it is equally well known that the ethnographic method based on participant observation has been, since the 1920s, taken as a foundation for anthropological research and for the scientific status of the knowledge acquired by its means. This essay has several purposes: highlighting some issues related to Malinowski’s theory and practice of research, which are full of implications not always grasped in their theoretical and methodological complexity; recalling some criticisms that have been put forward in the anthropological debate toward the notion of reflexive observation; discussing some uses and abuses of ethnographic pr…

La complejidad de la gobernanza del patrimonio inmaterial en el medio rural: el caso de «Els Pelegrins de Les Useres (provincia de Castellón)»
2019
En el nuevo escenario de modernidad avanzada se observan nuevas dinámicas de patrimonialización que pueden significar una oportunidad para los espacios rurales, pero también una amenaza. Desvelar cómo los diferentes agentes tanto globales como locales en el territorio van tejiendo buenas y malas prácticas, y cuáles son las dificultades, las contradicciones y los conflictos con los que se encuentran tan solo es posible a través de un enfoque interdisciplinar que aúne la visión territorial, constructivista y comunitaria. Este artículo tiene como objetivo identificar y diferenciar dos dinámicas de patrimonialización poniendo el acento en cómo se construyen estos procesos, diferenciando dos eje…
