Statistical Analysis of V85 Models on Horizontal Curves of Italian Two-Lane Rural Roads

Injuries are one of the main causes of death according to the new report published by WHO (World Health Organization). For this reason the attention of road safety research especially regards the study of the relationship between driver and road environment, in order to obtain a reduction of injuries number and severity. Several studies were developed to find the relationships between road geometrical and design features and driver behaviour. Generally driver behaviour is expressed by the operating speed. In scientific literature there exist several analytical models to calculate real speed as a function of geometrical road characteristics. In this work some of them were collected and their hypotheses were studied. Generally the values of these parameters were similar in the majority of the models and they can be found in the Italian rural roads in order to make surveys. The next step was the statistical analysis of the existing models with hypotheses that could be applied to Italian roads in order to define the best one

Brain connectivity changes after osteopathic manipulative treatment: A randomized manual placebo-controlled trial

The effects of osteopathic manipulative treatment (OMT) on functional brain connectivity in healthy adults is missing in the literature. To make up for this lack, we applied advanced network analysis methods to analyze resting state functional magnetic resonance imaging (fMRI) data, after OMT and Placebo treatment (P) in 30 healthy asymptomatic young participants randomized into OMT and placebo groups (OMTg; Pg). fMRI brain activity measures, performed before (T0), immediately after (T1) and three days after (T2) OMT or P were used for inferring treatment effects on brain circuit functional organization. Repeated measures ANOVA and post-hoc analysis demonstrated that Right Precentral Gyrus (F (2, 32) = 5.995, p < 0.005) was more influential over the information flow immediately after the OMT, while decreased betweenness centrality in Left Caudate (F (2, 32) = 6.496, p < 0.005) was observable three days after. Clustering coefficient showed a distinct time-point and group effect. At T1, reduced neighborhood connectivity was observed after OMT in the Left Amygdala (L-Amyg) (F(2, 32) = 7.269, p < 0.005) and Left Middle Temporal Gyrus (F(2, 32) = 6.452, p < 0.005), whereas at T2 the L-Amyg and Vermis-III (F(2, 32) = 6.772, p < 0.005) increased functional interactions. Data demonstrated functional connectivity re-arrangement after OMT

Cerebellar structural variations in subjects with different hypnotizability

Hypnotizability-the proneness to accept suggestions and behave accordingly-has a number of physiological and behavioral correlates (postural, visuomotor, and pain control) which suggest a possible involvement of cerebellar function and/or structure. The present study was aimed at investigating the association between cerebellar macro- or micro-structural variations (analyzed through a voxel-based morphometry and a diffusion tensor imaging approach) and hypnotic susceptibility. We also estimated morphometric variations of cerebral gray matter structures, to support current evidence of hypnotizability-related differences in some cerebral areas. High (highs, N = 12), and low (lows, N = 37) hypnotizable healthy participants (according to the Stanford Hypnotic Susceptibility Scale, form A) were submitted to a high field (3 T) magnetic resonance imaging protocol. In comparison to lows, highs showed smaller gray matter volumes in left cerebellar lobules IV/V and VI at uncorrected level, with the results in left lobule IV/V maintained also at corrected level. Highs showed also gray matter volumes smaller than lows in right inferior temporal gyrus, middle and superior orbitofrontal cortex, parahippocampal gyrus, and supramarginal parietal gyrus, as well as in left gyrus rectus, insula, and middle temporal cortex at uncorrected level. Results of right inferior temporal gyrus survived also at corrected level. Analyses on micro-structural data failed to reveal any significant association. The here found morphological variations allow to extend the traditional cortico-centric view of hypnotizability to the cerebellar regions, suggesting that cerebellar peculiarities may sustain hypnotizability-related differences in sensorimotor integration and emotional contro

Perceived importance of facilitators to cycling: the case of a starter cycling city in Italy

The goal of this study is to understand and explore how facilitators to cycling are perceived by different segments of individuals, in view of assessing how to best promote the use of the bicycle in urban areas bicycle-unfriendly. The data for this study is drawn from a survey conducted in the metropolitan area of Cagliari, a starter cycling city in Italy, in 2014-2016 among a sample of local employees. The sample comprises 1,481 observations. All participants were asked to rate, by means of a 5-point Likert Scale, the importance of eight different specified factors that would encourage them to start cycling or to cycle more often. These factors, which are the dependent variables of our study, are modelled jointly using a multivariate ordered probit framework. Our results clearly indicates that how people perceive the implementation of policy measures aimed to encourage more frequent cycling depends on their socio-demographic characteristics. Hence, a holistic approach with a variety of activities is needed, as improvements in cycling infrastructure may not be enough

‘Homemade’: Building, mending, and coordinating a care network

In recent decades, longer life expectancy, the consequent greater number of patients with often concurrent diseases, and the need of healthcare institutions to reduce the costs of services, have engendered changes in all European healthcare systems. On one side, healthcare systems increasingly rely on the self-management skills of patients, who undertake a growing amount of ‘sickness work’ from which they are relieved only in the case of severe illness. On the other, the inability of public healthcare systems to satisfy the increased demand for care has led to the growth of private healthcare organizations as well as cooperatives of health professionals who offer their services privately. The care of citizens, therefore, is increasingly distributed across networks of actors with very different objectives, logics of action and professional backgrounds (public and private healthcare organizations, community medical services, voluntary organizations). Despite the attention devoted by social studies of medicine to the work done by citizens in supporting the work of clinicians and nurses, the work performed in connection to the management of care networks have been only marginally investigated. Drawing on a qualitative research carried out in the Province of Trento (Italy) and focused on the different ways in which elderly people with chronic conditions manage their conditions outside the healthcare and welfare institutions, in this paper we are interested in deepening the understanding of the invisible work citizens perform in connection to the management of care services and professionals. That is, the work needed in order to activate, mend and coordinate complex networks of care

Vulnerability assessment of concrete bridges using different methods of visual inspection

This paper shows the comparisons between different methods of visual inspection used in European Countries. These methodologies are applied to the deck bridge located near Cagliari, along the SS 195 road to Capoterra. From a strategic point of view, this structure plays a key role ensuring a direct connection to different structures related to industrial and local productions and to an important touristic district. This is a prestressed concrete bridge in an aggressive marine environment, which in October 2008 was hit by a flood that caused subsidence in the foundations. The aim of our inspection is to obtain a real measure of the vulnerability through different procedures and to determine which is the best method able to give objective results

Measuring Implicit European and Mediterranean Landscape Identity: A Tool Proposal

This study presents a tool - the Landscape Identity Implicit Association Test (LI-IAT) - devoted to measure the implicit identification with European and Mediterranean landscapes. To this aim, a series of prototypical landscapes was selected as stimulus, following an accurate multi-step procedure. Participants (N = 174), recruited in two Italian cities, performed two LI-IATs devoted to assess their identification with European vs. Not-European and Mediterranean vs. Not-Mediterranean prototypical landscapes. Psychometric properties and criterion validity of these measures were investigated. Two self-report measures, assessing, respectively, European and Mediterranean place identity and pleasantness of the target landscapes, were also administered. Results showed: (1) an adequate level of internal consistency for both LI-IATs; (2) a higher identification with European and Mediterranean landscapes than, respectively, with Not-European and Not-Mediterranean ones; and (3) a significant positive relationship between the European and Mediterranean LI-IATs and the corresponding place identity scores, also when pleasantness of landscapes was controlled for. Overall, these findings provide a first evidence supporting the reliability and criterion validity of the European and Mediterranean LI-IATs
