Victims of scenario-thinking. On the making of optimism and unrealistic expectations about ICTs
No full textThe pervasiveness of ICTs in healthcare is modifying professional-patient relationship. The de- bate, as often happens with innovations, is polarized and technology is considered with enthusiasm or sheer pessimism. Several works have tried to move beyond this simplistic positioning and address the intricacies and complexities of adopting technologies (Pols 2012; Piras and Miele 2020). Despite such efforts, the dichotomy tends to repeat itself and to move beyond we need to understand how this is created and reinforced.
Focusing on the professional community of computer scientists, the paper analyzes techno- enthusiasm to understand how it originates, how it is re-created over time and discursively performed and enacted.
The argumentation will be twofold. Firstly, I will show how the professional culture of informatics is imbued with high expectations with regard to the possibility of reshaping society through technology. In the scientific community, these values are promoted favoring the presentation of success cases instead of reflections about failures.
Secondly, I shall focus on the role of ‘scenarios’ in shaping an enthusiastic perspective with regard to technology. Scenarios, formally created to present a realistic use case, are powerful rhetorical devices that shape the desired future and foster a culture techno-enthusiasm by oversimplifying the complexities that technology will need to address thus making possible develop over-optimistic expectations regarding its adoption.
I argue that both techno-enthusiasm and techno-pessimism, far from being personal positioning, demarcate professional boundaries they are reproduced in patterned activities. Moving beyond the dichotomy requires identifying the locus and the practices in which each professional community performs and reinforces between techno-enthusiasm or techno-pessimism.

Recovery time profiling after short-, middle-and long-distance swimming performance
No full textPiras, A, Cortesi, M, Campa, F, Perazzolo, M, and Gatta, G. Recovery time profiling after short-, middle- and long-distance swimming performance. J Strength Cond Res 33(5): 1408-1415, 2019-We investigated cardiac autonomic responses and hemodynamic parameters on recovery time after short-, middle- and long-swimming performance. Ten male regional-level swimmers were tested to estimate time and frequency domains of arterial baroreflex sensitivity (BRS) and heart rate variability after 100, 200, and 400 m of front crawl. We found a BRS reduction for 90 minutes after a maximal 100- and 200-m front crawl event, meanwhile the reflex was restored back to the baseline value approximately 70 minutes after 400 m. The vagally mediated high-frequency power of R-R intervals was significantly reduced for 30 minutes after 400 m, and more than 90 minutes after 100 and 200 m, with a concomitant increase of sympathetic modulation. After 400 m, athletes have reduced their stroke volume for 50 minutes, which remained at the baseline level after 100 and 200 m. Heart rate was restored back after 90 minutes in all conditions, whereas total peripheral vascular resistance was significantly reduced for 50 minutes after 200 and 400 m, with a persistent reduction after 100 m. Time course of autonomic recovery after 3 different swimming performances is influenced by exercise intensity and duration, showing a rapid recovery after 400 m, an intermediate recovery after 200 m, and a significantly delayed recovery after a more strictly anaerobic performance like 100 m of front crawl. These results could encourage coaches to consider that athlete might be affected by the specific recovery time of the previous exercise performed, suggesting that the management of the exercise intensity, and appropriate monitoring of cardiac autonomic parameters might be helpful to know the physical condition of each athlete

Abstract
The oxidation of organosulphides catalysed by hydrogen bonding donors derived from aminotetrazole has been studied. The oxidation reaction was performed in a H2O solution using H2O2 as a versatile, green and chemoselective new approach to sulphoxides. Sulphoxide compounds are obtained in high yields and excellent selectivity through a new and easy to perform oxidation protocol. Aminotetrazole derivatives can be recycled by filtration and reused several times without expensive purification procedures
