Moving too fast? Addressing temporality and acceleration in Portuguese business ventures scaling

In recent years, Portugal has been increasingly credited as an emergent European entrepreneurial and technological hub, a rising and promising start-up nation. An ethnographic study was developed in one of the most successful start-up ventures operating in Portugal, with the goal of scrutinizing policy effectiveness in an employment creation and relations perspective. Considering the effect temporality regimes and acceleration are increasingly considered to have as new business ventures socioeconomic base, the study focus was placed on speeding-up implications, namely on how actors experience speed as infrastructural base of employment relations.In recent years, Portugal has been increasingly credited as an emergent European entrepreneurial and technological hub, a rising and promising start-up nation.

Afin d’analyser l’efficacité des politiques publiques de soutien à l’entrepreneuriat, une étude ethnographique a été réalisée dans l’une des start-up les plus performantes opérant au Portugal. Compte tenu du rôle qui a été attribué aux usages du temps, de la temporalité et de l’accélération comme base socio-économique des nouvelles entreprises économiques, l’étude s’est concentrée sur les implications de l’accélération, en termes de la façon dont les acteurs vivent la vitesse comme base l’infrastructure de (leurs) relations de travail.En los últimos años, Portugal se ha visto cada vez más como un centro tecnológico europeo emergente, una nación emergente prometedora.

Ventricular Mass in Relation to Body Size, Composition, and Skeletal Age in Adolescent Athletes

Objective: To examine the contribution of chronological age (CA), skeletal age (SA), stature, sitting stature, fat-free mass (FFM), and fat mass (FM) to interindividual variability in left ventricular mass (LVM) in male adolescent roller hockey players using allometric models. Design: Cross sectional. Setting: Training and competitive sport during adolescence. Participants: Seventy-three Portuguese male roller hockey players aged 14.5 to 16.5 years. Independent Variables: Stature, sitting stature, body mass, estimated FM and FFM, and SA assessed by the Fels method. Main Outcome Measures: Allometric modeling of LVM assessed in accordance with recommendations of the American Society of Echocardiography. Results: Hockey players (CA: 15.4 +/- 0.6 years; SA: 16.4 +/- 1.5 years) showed an eccentric remodeling of LV structure within the reference range (ie, 0.24-0.42), a dilated LV chamber, but no LVM increase. Exponents for body size descriptors were 2.69 for stature (R-2 = 27%; P <0.001), 2.49 for sitting stature (R-2 = 37%; P <0.001), 0.76 for FFM (R-2 = 31%; P <0.001), and 0.22 for FM (R-2 = 26%; P <0.001). The combination of size descriptors with CA and SA increased the explained variance in LVM slightly (26%-45%). Conclusions: When stature and FM are used for indexing LVM in a sample of adolescent athletes, biological maturity status should also be considered
