Producción, precios e integración de los mercados regionales de grano en la España preindustrial
No full textEditada en la Fundación Empresa PúblicaEste trabajo aborda la integración de los distintos mercados regionales
de grano en España durante el Antiguo Régimen. Haciendo uso de series
de precios y de producción de diversa procedencia, el autor emplea técnicas
de estimación relativamente sencillas, desde correlaciones y desviaciones típicas
de series sin tendencia hasta modelos de retardos distribuidos. Estas técnicas
revelan la existencia de una covariación entre los precios de granos
en distintos mercados regionales, así como la existencia de efectos simultáneos
y retardados de la producción de granos sobre el precio de los mismos en
mercados locales y bastante más lejanos. El autor concluye que existía una
integración modesta pero en aumento de los distintos mercados en la Península,
sobre todo durante el siglo XVIII, y que las instituciones eran capaces
de amortiguar en parte los efectos de una cosecha fallida. El trabajo concluye
apuntando el calendario posible de la progresiva integración de los mercados
de grano ocurrida a lo largo de buena parte del siglo XIX en España.The present paper deals with regional grain market integration in Spain
during the Old Regime. Using mostly published price and production seríes,
the author employs straightforward statistical techniques, rangíng from correlations
and standard deviations of detrended series to distributed lag models.
These techniques show the existence of a clear covariation in the price of
grain on different regional markets, as well as both simultaneous and delayed
effects of grain production on prices both locally and at considerably greater
distances. The author concludes that regional grain markets on the peninsula
were modestly but increasingly integrated over the period, especially during
the eighteenth century, and that existing institutions were a partial buffer
for the immediate effects of harvest failures. The paper concludes by suggesting
the potential timing for the progressive intergration of grain markets taking
place throughout much of the nineteenth century in Spain.Publicad

No full textThe role of tnf-alpha and tnf superfamily members in the pathogenesis of calcific aortic valvular disease
No full textCalcific aortic valve disease (CAVD) represents a slowly progressive pathologic process associated with major morbidity and mortality. The process is characterized by multiple steps: inflammation, fibrosis, and calcification. Numerous studies focalised on its physiopathology highlighting different “actors” for the multiple “acts”. This review focuses on the role of the tumor necrosis factor superfamily (TNFSF) members in the pathogenesis of CAVD. In particular we discuss on clinical and experimental studies providing evidence of the involvement of tumor necrosis factor alpha (TNF-α), receptor activator of nuclear factor kappa-B (NF-kB) ligand (RANKL), its membrane receptor RANK and its decoy receptor osteoprotegerin (OPG), and TNF-related apoptosis-inducing ligand (TRAIL) in valvular calcification
Profezie che si autoavverano, stili degli allenatori e motivazioni verso lo sport: una ricerca condotta su giovani Judoka/ Self-fulfilling prophecies, coaches' orientations and sport motivations. A study on young Judokas
No full textDifferent studies have shown that when tutors are more supportive of autonomy and less controlling the trainees demonstrate higher level of intrinsic motivation. The present study, carried out in the context of Judo' s classroom, analysed the role of tutor's beliefs about a trainee in influencing this relation. Thirty tutors and thirty trainees participated in the study. Each tutor supervised a trainee during a 30 minutes period of training. Tutors were given no information regarding the trainee (group N; n=10) ,were told that the trainee was intrinsically motivated (group I, n=10) or that the trainee was extrinsically motivated (group E, n=10).
Results show that trainees who were believed to be intrinsically motivated perceived their tutors as being more supportive of their autonomy, reported to feel themselves as more interested in the training session and spent more time during a free choice period.Different studies have shown that when tutors are more supportive of autonomy and less controlling the trainees demonstrate higher level of intrinsic motivation.

Agricultural Genetics and Plant Breeding in Early Twentieth-Century Italy
No full textThis thesis is about plant breeding in Early 20th-Century Italy. The stories of the two most prominent Italian plant-breeders of the time, Nazareno Strampelli and Francesco Todaro, are used to explore a fragment of the often-neglected history of Italian agricultural research. While Italy was not at the forefront of agricultural innovation, research programs aimed at varietal innovation did emerge in the country, along with an early diffusion of Mendelism. Using philosophical as well as historical analysis, plant breeding is analysed throughout this thesis as a process: a sequence of steps that lays on practical skills and theoretical assumptions, acting on various elements of production. Systematic plant-breeding programs in Italy started from small individual efforts, attracting more and more resources until they became a crucial part of the fascist regime's infamous agricultural policy. Hybrid varieties developed in the early 20th century survived World War II and are now ancestors of the varieties that are still cultivated today. Despite this relevance, the history of Italian wheat hybrids is today largely forgotten: this thesis is an effort to re-evaluate a part of it. The research did allow previously unknown or neglected facts to emerge, giving a new perspective on the infamous alliance between plant-breeding programs and the fascist regime. This thesis undertakes an analysis of Italian plant-breeding programs as processes. Those processes had a practical as well as a theoretical side, and involved various elements of production. Although a complete history of Italian plant breeding still remains to be written, the Italian case can now be considered along with the other case-studies that other scholars have developed in the history of plant breeding. The hope is that this historical and philosophical analysis will contribute to the on-going effort to understand the history of plants
