A typology of theatre audiences based on the impact of various sources of influence and the use of information channels
2020
En: Doxa Comunicación: revista interdisciplinar de estudios de comunicación y ciencias sociales. e-ISSN 2386-3978 n. 30, 2020, pp 127-143. Este estudio presenta una tipología de espectadores teatrales que contempla la influencia de los medios de comunicación y otras instancias de prescripción en sus decisiones de asistencia al teatro, un aspecto no abordado por ninguna investigación previa. La investigación se basa en una encuesta a 210 asistentes a representaciones teatrales de tres salas de la ciudad de Valencia. La aplicación de diversas técnicas estadísticas multivariables ha permitido identificar una tipología de cuatro perfiles de consumidores escénicos: los informados-alternativos, l…
Panel Summary: Planning and Problem Solving
1999
I will sketch some ideas that have guided the psychological approaches to problem solving. Traditionally, psychologists have considered the ability to solve problems “one of the most important manifestations of human thinking”. 1 Moreover, “problem” has been defined as a search that starts when we have a goal, but our habitual means are not sufficient to achieve it.
Bonding efficacy of an acetone/based etch-and-rinse adhesive after dentin deproteinization
2012
Objectives: to evaluate the effect of sodium hypochlorite (NaOCl) treatment on dentin bonding by means of shear bond strength (SBS) measurements when using Prime&Bond NT (PB NT) adhesive. Ultrastructure of the interfaces was examined by scanning electron microscopy (SEM). Study design: Extracted human third molars were sectioned and ground to expose flat surfaces of superficial or deep dentin. Specimens were randomly assigned to two equal groups, and bonded as follows: (1) according to the manufacturers’ directions, after 35% H3PO4 etching, (2) 5% NaOCl treated for 2 minutes, after 35% H3PO4 etching. Each sample was embedded in a Watanabe shear test assembly for a single plane lap shear. Af…
Mechanical and neural stretch responses of the human soleus muscle at different walking speeds
2009
During human walking, a sudden trip may elicit a Ia afferent fibre mediated short latency stretch reflex. The aim of this study was to investigate soleus (SOL) muscle mechanical behaviour in response to dorsiflexion perturbations, and to relate this behaviour to short latency stretch reflex responses. Twelve healthy subjects walked on a treadmill with the left leg attached to an actuator capable of rapidly dorsiflexing the ankle joint. Ultrasound was used to measure fascicle lengths in SOL during walking, and surface electromyography (EMG) was used to record muscle activation. Dorsiflexion perturbations of 6 deg were applied during mid-stance at walking speeds of 3, 4 and 5 km h(-1). At eac…

Even though the acute effects of pre-exercise static stretching and dynamic muscle activity on muscular and functional performance have been largely investigated, their effects on the corticospinal pathway are still unclear. For that reason, this study examined the acute effects of 5×20 s of static stretching, dynamic muscle activity and a control condition on spinal excitability, corticospinal excitability and plantar flexor neuromuscular properties. Fifteen volunteers were randomly tested on separate days. Transcranial magnetic stimulation was applied to investigate corticospinal excitability by recording the amplitude of the motor-evoked potential (MEP) and the duration of the cortical s…
Effects of prolonged walking on neural and mechanical components of stretch responses in the human soleus muscle
2009
After repeated passive stretching, tendinous tissue compliance increases in the human soleus (SOL) muscle–tendon unit. During movement, such changes would have important consequences for neural and mechanical stretch responses. This study examined the existence of such effects in response to a 75 min walking intervention. Eleven healthy subjects walked on a treadmill at 4 km h−1 with a robotic stretch device attached to the left leg. Ultrasonography was used to measure SOL fascicle lengths, and surface EMG activity was recorded in the SOL and tibialis anterior (TA) muscles. Perturbations of 6 deg were imposed at three different measurement intervals: Pre (immediately before the walking inte…
I libri, la biblioteca, la città
2021
Molti e suggestivi sono i modi per declinare il tema dei libri e della città. Il primo è quello che legge e interpreta le corrispondenze tra alcuni libri e specifiche città, con un approccio solo apparentemente letterario poiché potrebbe orientare a considerazioni di carattere spaziale oltre che storico e sociale. Un secondo aspetto guarda ai libri e agli spazi intesi come elementi di mediazione (o di interazione) con la città: sono le biblioteche che danno presenza ai libri e che si offrono come luoghi della cultura: Rappresentano lo spazio dei libri nella città e della città. La prima questione, riguardante le simmetrie libri-città, è troppo affascinante per non essere accennata con qualc…
Immediate effects of the respiratory stimulation on ventilation parameters in ischemic stroke survivors: A randomized interventional study (CONSORT).
2019
Background: Post-stroke brain damage, which affects the central control of respiration, leads to various respiratory disorders. They can be caused by the weakening of the respiratory muscles and chest movements, which can indirectly contribute to an impairment of the ventilation function. The aim of the study is an objective assessment of the effect of a single-session intervention of respiratory stimulation through Proprioceptive Neuromuscular Facilitation (PNF) on chosen respiratory parameters and the following comparison of these changes with a group in which positioning was used (intra- and intergroup comparison). Methods: This was a randomized interventional study evaluating the respir…
EMG amplitude of the biceps femoris during jumping compared to landing movements.
2013
Abstract Hamstrings injury is a common occurrence in athletic performance. These injuries tend to occur during a deceleration or landing task suggesting the negative work may be a key component in hamstrings injury. The purpose of this study was to investigate the muscular activity (EMG) of the biceps femoris (BF) in different phases (concentric vs. eccentric) of a Counter Movement Jump (CMJ), Squat Jump (SJ) and the Braking Phase (BP) of a landing task. Twelve female volleyball players performed 5 CMJs, SJs and BPs while surface EMG was recorded using a MuscleLab (BoscoSystemTM, Norway). EMG values were normalized to an maximal voluntary contraction. A repeated measures analysis of varianc…
Note brevi a margine della proposta di riforma dei reati ambientali del gruppo di studio dell'associazione dei professori di diritto penale
2022
A partire dall’analisi della proposta di riforma dei reati contro l’ambiente elaborata dal Gruppo di studio dell’Associazione italiana dei Professori di Diritto Penale, il contributo riflette sui principali problemi teorici del diritto penale ambientale (tipizzazione dell’evento lesivo nelle fattispecie di inquinamento e di disastro ambientale, imputazione soggettiva dei delitti aggravati dall’evento, contrasto penale alle c.d. “ecomafie” nel settore dei rifiuti ecc.), mettendo a confronto le soluzioni suggerite nel testo con le prospettive di riforma contenute nella recente Proposta di Direttiva del Parlamento europeo e del Consiglio sulla Protezione dell’ambiente at- traverso il diritto p…
