Luck vs Skill in Gambling over the Recession. Evidence from Italy

We perform an econometric analysis of the gambling market in Italy over the recession (2009-2012), observing the consumption patterns in "luck" and "skill" games. We find a different effect between the early and late period of the crisis. Whereas gambling initially behaves as normal good, in the long run luck games increase with the worsening of economic conditions. Moreover, skill games are more persistent and influence luck games, but not the opposite. Skill players choose simple lottery games, but luck players cannot handle complex games. Our results provide insights on investment choices in financial markets among expert and naïve buyers

Eco labels and tourism flows: How much is a Blue Flag worth?

The rise in destination accessibility and the emergence of new market segments have increased the competition among tourism destinations, both at national and international level. In order to gain a significant competitive advantage over competitors, destinations increasingly make use of signals that certify and communicate the level of quality provided. While existing research on tourism certifications mostly pertains to quality evaluation, this study exploits quantitative methods to assess the economic impact of destinations’ labels. The analysis considers one of the most popular certification of environmental quality attributed to beaches, the Blue Flag award. It explores the relationship between the certification achievement and inbound tourist flows, focusing on the Italian case study. In fact, given their aim of providing synthetized information on destinations, certification programs particularly affect foreign tourists who suffer more from asymmetric information. Panel data techniques and highly disaggregated data are employed to compare the attractiveness of certified and non-certified provinces, by controlling for several factors potentially confounding the effect of the certification

Energy absorption in actual tractor rollovers with different tire configurations

In order to better understand the complexities of modern tractor rollover, this paper investigates the energy absorbed by a Roll-Over Protective Structure (ROPS) cab during controlled lateral rollover testing carried out on a modern narrow-track tractor with a silent-block suspended ROPS cab. To investigate how different tractor set-ups may influence ROPS and energy partitioning, tests were conducted with two different wheel configurations, wide (equivalent to normal ‘open field’ operation) and narrow (equivalent to ‘orchard/vineyard’ operation), and refer to both the width of the tires and the corresponding track. Dynamic load cells and displacement transducers located at the ROPS-ground impact points provided a direct measurement of the energy absorbed by the ROPS cab frame. A trilateration method was developed and mounted onboard to measure load cell trajectory with respect to the cab floor in real-time. The associated video record of each rollover event provided further information and opportunity to explain the acquired data. The narrow tire configuration consistently subjected the ROPS cab frame to more energy than the wide tire arrangement. To better evaluate the influence of the ROPS cab silent-blocks in lateral rollover, static and dynamic tests were performed. The results confirm that tires influence the energy partition significantly and that further understanding of silent-blocks’ dynamic performance is warranted

Chemical variability of artificial stone powders in relation to their health effects

The occurrence of highly severe silica-related diseases among the resin- and silica-based artificial stone workers was claimed, associated to an extremely short latency. High levels of exposure and intrinsic properties of AS are thought to modulate the development of silicosis and auto-immune diseases. This study compares parent materials and processed dusts, to shed light on changes of AS occurring in the manufacturing process, through an XRF, EPR and XAS investigation. We point out the extremely wide variability of the materials, the occurrence of chemical signatures impressed by the processing techniques, and the unprecedented generation of stable radicals associated to the lysis of the Si-O chemical bond inside the resin coated respirable crystalline silica. These results suggest that the AS processing in industrial stone workshops can create respirable dusts with peculiar physical and chemical properties, to be correlated to the observed clinical evidences
