Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation
2021
The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been introduced into the traffic mix alongside conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs, compared to roundabouts without such curbs. The paper will then describe the methodological path followed to build VISSIM models of turbo-roundabouts with and without raised curbs in …
Do Older Employees Suffer More from Work Intensification and Other Intensified Job Demands? Evidence from Upper White-Collar Workers
2019
Background: Working life today is characterized by acceleration and intensification due to social, and particularly technological, acceleration affecting the whole of society. These phenomena also affect working life by intensifying job demands, possibly imposing new job stressors on the workforce. At the same time workforce is aging, raising a question how older employees manage to cope with these work life changes. Methods: This study examined intensified job demands and their effects on occupational well-being from the age perspective utilizing Finnish survey data from upper white-collar workers (N = 2,200). Data was analyzed using multivariate analysis of covariance and hierarchical reg…
Childhood physical activity as a labor market investment
2021
This study examined the role of physical activity and changes in physical activity levels during childhood in long‐term labor market outcomes. To address this important but under‐researched theme, the study utilized data drawn from longitudinal research, the Cardiovascular Risk in Young Finns Study (YFS), and from registries compiled by Statistics Finland. The study consisted of children aged 9 (n=1565) and 15 (n=2445) at the time their physical activity was measured. Labor market outcomes, including employment status, average employment months, and average unemployment months, were calculated from 1997 to 2010, when the participants were aged 20 to 48 years. Regression models were used to …
Real-world experience with obeticholic acid in patients with primary biliary cholangitis
2021
Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…
Nonlinear black-box models for short-term forecasting of air temperature in the town of Palermo
2011
Weather data are crucial to correctly design buildings and their heating and cooling systems and to assess their energy performances. In the intensely urbanized towns the effect of climatic parameters is further emphasized by the Urban Heat Island (UHI) phenomenon, known as the increase in the air temperature of urban areas, compared to the one measured in the extra-urban areas. The analysis of the heat island needs detailed local climate data which can be collected only by a dedicated weather monitoring system. The Department of Energy and Environmental Researches of the University of Palermo (Italy) has built up a weather monitoring system that works 24 hours per day and makes data availa…
Automatic evaluation of information provider reliability and expertise
2013
Published version of an article in the journal: World Wide Web. Also available from the publisher at: http://dx.doi.org/10.1007/s11280-013-0249-x Q&A social media have gained a lot of attention during the recent years. People rely on these sites to obtain information due to a number of advantages they offer as compared to conventional sources of knowledge (e.g., asynchronous and convenient access). However, for the same question one may find highly contradicting answers, causing an ambiguity with respect to the correct information. This can be attributed to the presence of unreliable and/or non-expert users. These two attributes (reliability and expertise) significantly affect the quality o…
Big Data e accesso al credito degli immigrati: discriminazioni algoritmiche e tutela del consumatore
2020
The aim of this essay is to assess the capacity of innovative credit scoring techniques to improve financial inclusion of the unbanked. Given the lack of informations on immigrants creditworthiness, the use of Big Data analytics could be a useful tool, because it makes possibile to collect and analyze the huge quantity of data produced online by the consumer. According to the author, it is questionable the compliance of social network data with the requirements of the Testo Unico Bancario: according to articles 120 undecies and 124 bis, the data used in the creditworthiness assessment should be connected with the consumer’s ability to repay the debt. The essay, moreover, stress the need for…
Relational approach to infant-teacher lap interactions during the transition from home to early childhood education and care
2022
The transition from home care to early childhood education and care (ECEC) is a period of intense change and development in young children's socio-spatial worlds. This article focuses on infant–teacher lap interactions during this transition period. This investigation applies a relational approach to the study of infant–teacher lap interactions. In doing so, it highlights the inherently social and contextual nature of interaction. From a relational perspective, actors, context, and situation are seen as constitutive of each other, and their interrelationality is considered central to the emergence of interactions. The data, regarding infants' first months attending ECEC in Finland, is compo…
CYGD: the Comprehensive Yeast Genome Database.
2005
The comprehensive resource is available under http://mips.gsf.de/genre/proj/yeast/.; International audience; The Comprehensive Yeast Genome Database (CYGD) compiles a comprehensive data resource for information on the cellular functions of the yeast Saccharomyces cerevisiae and related species, chosen as the best understood model organism for eukaryotes. The database serves as a common resource generated by a European consortium, going beyond the provision of sequence information and functional annotations on individual genes and proteins. In addition, it provides information on the physical and functional interactions among proteins as well as other genetic elements. These cellular network…
