Opportunities and limitations of in-gas-cell laser spectroscopy of the heaviest elements with RADRIS
2022
International audience; The radiation detection resonance ionization spectroscopy (RADRIS) technique enables laser spectroscopic investigations of the heaviest elements which are produced in atom-at-a-time quantities from fusion-evaporation reactions. To achieve a high efficiency, laser spectroscopy is performed in a buffer-gas environment used to thermalize and stop the high-energy evaporation residues behind the velocity filter SHIP. The required cyclic measurement procedure in combination with the applied filament collection for neutralization as well as confinement of the stopped ions and subsequent pulse-heat desorption constrains the applicability of the technique. Here, some of these…
A radiometric and petrographic approach to risk assessment at Alte Madonie Mounts region (Sicily, Italy)
2013
The main goal of this work was to assess the radiological hazard at Alte Madonie Mounts region (north-central Sicily, Italy) in response to rumours of an increase in the incidence of cancer in this area. A correlation between the natural radionuclide contents and the petrographic features of the soil and rock samples was also evaluated. A total of 41 samples of selected soils and rocks were collected, powdered, dried and sealed in 'Marinelli' beakers for 20 d prior to measurement to ensure that a radioactive equilibrium between (226)Ra and (214)Bi had been reached. A gamma-ray spectrometer was used to quantify the radioactivity concentrations. To determine (238)U and (232)Th activities, the…
Free riding as méchanism
1998
Free-riding is methodologically puzzling. It is at the same time important and often not observed as an actual phenomenon. The paper explores the possibility of treating free riding as an underlying or causal mechanism. As such, free riding is to be treated as part of the real world rather than of the world of models or theories. However, the free riding mechanism is particularly prone to operate not in isolation but together with other mechanisms. This feature has consequences on issues such as empirical content, testability or relevance. These questions are discussed in the light of some recent work in philosophy of science and with special attention given to the development of experiment…

Immersive Versus Non-immersive Experience: Exploring the Feasibility of Memory Assessment Through 360° Technology
2019
Episodic memory is essential to effectively perform a number of daily activities, as it enables individuals to consciously recall experiences within their spatial and temporal environments. Virtual Reality (VR) serves as an efficacious instrument to assess cognitive functions like attention and memory. Previous studies have adopted computer-simulated VR to assess memory, which realized greater benefits compared to traditional procedures (paper and pencil). One of the most recent trends of immersive VR experiences is the 360° technology. In order to evaluate its capabilities, this study aims to compare memory performance through two tasks: immersive task and non-immersive task. These tasks d…
Family Structure and Subjective Economic Well-Being: Some New Evidence
2013
The paper investigates the main socio-demographic and economic determinants of subjective economic well-being in different typologies of households. Previous studies have used dummy variables to explore the effect of family structure. In this paper, however four different models—one for each family typology—have been estimated to test if each selected explanatory variable is significant and how it acts in determining the level of subjective economic well-being. To achieve this, we apply an under-used logit model—the partial proportional ordered model. Our analysis, based on data from the 2005 Italian Survey on Income and Living Conditions highlights the main variables affecting the subjecti…
Motor Vehicles Not Used in Road Traffic Are Also Subject to Compulsory Insurance in Europe - CJEU Clarification in Case C-80/17
2019
The article analyses a recent significant case in the Court of Justice of the European Union on the extent of compulsory insurance in the field of motor insurance. The judgment delivered by the Grand Chamber of the CJEU on 04 September 2018 clarifies the obligation to conclude a motor insurance contract in a situation when a motor vehicle is no longer intended to be used in road traffic. If previously there was no doubt that motor vehicles that are used in road traffic are subject to compulsory insurance, it was unclear whether compulsory insurance in the field of motor insurance also extends to vehicles which are no longer intended to be used in road traffic. The Court formulated the ‘thre…
Identifying Portfolio-Based Systematic Risk Factors in Equity Markets
2015
Four new prominent asset pricing factors have recently been proposed. We test whether these factors fulfill necessary conditions for qualifying those as risk factors. We show that the investment and betting-against-beta factors fulfill these conditions. However, the profitability and quality factors do not fulfill these conditions pointing towards non-risk-based explanations.
Psychological State after an Acute Coronary Syndrome: Impact of Physical Limitations
2021
The aim of this study was to investigate how physical limitations after ACS influence patients’ quality of life and health perception. This was a longitudinal clinical study. We recruited 146 patients diagnosed with ACS. The patients performed a stress test (Bruce’s protocol) for the evaluation of physical limitations and were classified according to the test result: without physical limitations (more than 10 METS), with some physical limitations (7 to 9 METS), and with high physical limitations (less than 6 METS). Significant differences were found between the three groups immediately after the diagnosis of ACS and after a period of three months, regarding health perception, anxiety, depre…
