Pro Free Will Priming Enhances "Risk-Taking" Behavior in the Iowa Gambling Task, but not in the Balloon Analogue Risk Task : Two Independent Priming Studies

Studies indicated that people behave less responsibly after exposure to information containing deterministic statements as compared to free will statements or neutral statements. Thus, deterministic primes should lead to enhanced risk-taking behavior. We tested this prediction in two studies with healthy participants. In experiment 1, we tested 144 students (24 men) in the laboratory using the Iowa Gambling Task. In experiment 2, we tested 274 participants (104 men) online using the Balloon Analogue Risk Task. In the Iowa Gambling Task, the free will priming condition resulted in more risky decisions than both the deterministic and neutral priming conditions. We observed no priming effects on risk-taking behavior in the Balloon Analogue Risk Task. To explain these unpredicted findings, we consider the somatic marker hypothesis, a gain frequency approach as well as attention to gains and / or inattention to losses. In addition, we highlight the necessity to consider both pro free will and deterministic priming conditions in future studies. Importantly, our and previous results indicate that the effects of pro free will and deterministic priming do not oppose each other on a frequently assumed continuum

Semi High Speed Steels for Roughing Rolls with improved Thermal Fatigue Resistance

Thermal fatigue represents one of the most significant causes for roughing mill roll deterioration and possible failure. The materials ability to withstand thermal cycling is strictly correlated to its microstructural properties, which are the result of the solidification process and following heat treatment. Rolls for hot strip rolling mills are usually produced by centrifugal casting, without subsequent forging. A crucial role is played by the eutectic carbide network developing on solidification, which represents a preferential pattern for crack propagation. For this reason conventional highly alloyed HSS are not a popular substitute for traditional Chromium steel rolls in rougher stands. The so - called “semi-HSS”, containing less C (0.7-0.9 %C) and alloying elements are usually preferred by users requiring improved roll material. Specially developed “HSS for roughers” are being tested in various mills, but they are out of the scope of this paper. The present work is part of a continuing effort by INNSE Cilindri (RIVA Group) and Trento University to improve the “semi HSS” grades. In particular the thermal fatigue resistance of a new class of low-C semi HSS is evaluated. For purpose of comparison, both a conventional semi-HSS and a HSS grade were also considered. The test is based on induction heating (Tmax=670°C) and water cooling of cylindrical discs. Experimental results confirm the lower susceptibility towards heat checking of the new grades, containing reduced amount of eutectic carbides, the best behaviour being exhibited by a steel with a mixed martensite-bainite matrix microstructure

Contrôle mécanique des plantes aquatiques

Inspired from agricultural machinery, various mechanical equipments used to control plants have been adapted to the specific conditions of aquatic environments. The range of machinery available in France is quite large and is composed of classical weed cutting equipment, of reaping ships and of multiple types of machines. The impacts of these techniques on the environment are numerous, which means that an analysis of the situation is required before further action. / Dérivés du matériel agricole, divers matériels mécanisés permettant des travaux de contrôle des plantes ont été adaptés aux conditions particulières des environnements aquatiques. La gamme d'engins disponibles en France est relativement large et se compose d'appareils de faucardage classiques, de bateaux moissonneurs et d'engins de conceptions très diverses. Les impacts de ces techniques sur les milieux sont multiples et doivent obliger à une analyse préalable de la situation à traiter
