Sport and maximisation of the subjective perception of wellbeing: A trend analysis of sporting practises at the start of the 21st century.

We have seen a transformation in the development of sporting activities over recent decades. There are a number of social factors behind this. In this article, we report a longitudinal study of sporting activities in Spain between 1995 and 2014 among the population aged 18 and over, including both sexes, examining the social relationships that arise in sporting activities. Our analysis is based on national databases and analysis of trends in sporting activities. It demonstrates the main hypothesis of the study, which is that individual sporting activities have increased compared to group activities with family and friends. We also examine changes in sporting activities depending on the primary relations established in the sport, by sex, age, habitat, occupation, educational level, the form in which the sport is practised, the degree of competition, frequency, the sports facilities used, the type of sport, hours of free time and the subjective sensation of happiness

MSB: Una aplicacion WWW para generación de resúmenes de comportamiento

La disponibilidad en Internet de grandes volúmenes de información en los que se basan decisiones relacionadas con el funcionamiento de sistemas dinámicos hace que cada vez sean más necesarios métodos efectivos de generación automáti-ca de resumen de información de comportamiento. En este artículo se describe la aplicación MSB (Multimedia Summari-zer of Behavior) como una herramienta software que genera presentaciones multimedia de resumen de comportamiento de sistemas dinámicos para ser presentadas en la Web. MSB usa como entrada datos de comportamiento de fuentes remo-tas (medidos por sensores) que pueden estar disponibles en diferentes servidores Web. Estas fuentes de información se interpretan y resumen usando métodos del campo de la Inteligencia Artificial simulando formas de razonamiento que realizan las personas al resumir información de interés. En el artículo se describe la arquitectura basada en el conocimien-to del sistema MSB y la aplicación desarrollada en el dominio de hidrología sobre comportamiento de cuencas hidrográ-ficas

(INFLUENCE OF Lactobacillus farciminis ON FERMENTATION IN LARGE INTESTINE AND PRODUCTION OF GASES ON IN VITRO IN HORSE)

The current study was outlined to investigate the influence of fecal inocula obtained from horses supplemented with Lactobacillus farciminis (L. farciminis) in diets constituting 50% oat straw on in vitro gas production (GP), methane (CH4), and carbon dioxide (CO2) productions as indicators of hindgut activity. The experiments were assessed on four Azteca horses ranging from 5 to 8 years of age, weighing 480±20.1 kg. The treatments comprised the in vitro incubation of fecal inocula with commercial product of L. farciminis at 0, 2, 4, and 6 mg/g dry matter (DM) of substrate. The fecal content mixed with the culture media were used to inoculate into the substrate containing a mixture of commercial concentrate and oat straw (1:1 DM). The subsequent incorporation of additives resulted into increased level of asymptotic GP, CH4, and CO2 productions (P0.05; quadric, P>0.05). A significant reduction in the fermentation pH range (linear, P=0.029) and higher metabolizable energy (ME) values (P=0.001) were obtained with the supplementation of L. farciminis in a dose dependent manner, whereas no impact of additives were reported on DMD (dry matter degraded) values (P>0.05). The in vitro GP, CH4, and CO2 productions were measured up to 48 h post incubation using standard methodology, and depicted 24 higher responses. The additives at varied concentrations resulted in increased in vitro GP, CH4, and CO2 productions (linear, P≤0.001) from 6 to 48 h of incubation. In conclusion, the dose dependent addition of L. farciminis (2 to 6 mg/g DM of diet) found to be persuasive in terms of attaining amicable hindgut fermentation in order to digest fibrous forage by horses without any side effect

Notes on a Reinvented Field

UIDB/00417/2020 UIDP/00417/2020The special section “Immersion and expanded spectatorships” discusses how moving images have been intensely reinvented in recent virtual environments, promoting renewed forms of viewing that change and broaden the spectator’s experience. Engaging with the fact that the history of immersive media is often difficult to reconstruct and categorize clearly, the four essays here gathered reflect precisely such plurality of research lines. Simultaneously, they further demonstrate how this field has for long been shaped — and continues to be so — in a hybrid manner, through fruitful dialogues and mutual contamination. O dossier temático “Imersão e experiências de receção expandidas” discute o modo como as imagens em movimento têm vindo a ser fortemente reinventadas em ambientes virtuais recentes, promovendo renovadas formas de visionamento que modificam e alargam a experiência dos seus espectadores. Considerando que a história dos média imersivos é frequentemente complexa de reconstruir e de categorizar de forma inequívoca, os quatro ensaios aqui reunidos procuram espelhar essa pluralidade de investigação, demonstrando como este é um campo que sempre se construiu — e continua a construir-se — hibridamente, através de profícuos diálogos e de contaminações mútuas.publishersversionpublishe
