This paper estimates food Engel curves using data from the first wave of the Survey on Health, Aging and Retirement in Europe (SHARE). Our statistical model simultaneously takes into account selectivity due to unit and item nonresponse, endogeneity problems, and issues related to flexible specification of the relationship of interest. We estimate both parametric and semiparametric specifications of the model. The parametric specification assumes that the unobservables in the model follow a multivariate Gaussian distribution, while the semiparametric specification avoids distributional assumptions about the unobservables. © 2011 John Wiley & Sons, Ltd.

Background and aims: In Italy, the prevalence of hypertension, obesity and overweight in paediatric patients has increased in the past years. The purpose of this study was to analyse the relationship between obesity and hypertension and related factors in Italian students. Methods and results: We studied 2007 healthy individuals between the ages of 6 and 17 years of age (998 males and 1009 females) attending schools in the cities of Varese (northern Italy), Rome (central Italy) and Catanzaro (southern Italy). The blood pressure, weight and height of the students were measured. We also assessed their daily intake of foods and the amount of physical activity they performed. A questionnaire was administered to the parents of the subjects to obtain information on the child's medical history and family lifestyle. Of the students, 27.2% were overweight, and 6.6% were obese, with the highest percentages in southern Italy. A total of 6.2% of students had hypertension, and the region with the highest percentage was found to be northern Italy. Obese students had a risk of developing hypertension that was four times greater than those subjects who were of normal weight. Conclusion: Overweight and obese children/adolescents were more frequently found in southern Italy as opposed to northern and central Italy, and hypertensive children were more prevalent in the north. An unhealthy diet might explain the more widely spread obesity among children living in the south; an excess use of salt could explain the greater rate of hypertension found among children/adolescents living in the north. •The purpose was to analyze the relationship between obesity and hypertension and related factors in young Italian students.•We studied healthy individuals between 6 and 17 years of age in three cities of different Italian regions.•We assessed blood pressure, weight, height, daily intake of foods and amount of physical activity.•We found highest percentage of overweight and obesity in southern Italy.•We found highest percentage of hypertension in northern Italy. © 2015 Elsevier B.V.

This paper focuses on innovative solutions to the problem of transparency in Public Administrations (PAs) by opening up public data and services so that citizens participation is facilitated and encouraged. We introduce the motivating principles and the architectural solutions to a Social Platform for Open Data, that is designed in order to provide a sustainable and re-usable framework to provide collaborative and social access to Open Data provided by PAs. Our overall objective is to propose a engage citizens by making them able to socially interact over Open Data, by forming or joining existing online communities that share common interest and discuss common issues of relevance to local policy, service delivery, and regulation. The proposed architectural solution is supporting the citizens in a collective relationship among them (as a network helping each other) and with PAs so that the information provided by the Public Administrations is shared, interpreted, personalized, made easier to understand and discussed to assess its meanings. The results and benefits of our approach, as well as potential impact in the pilot experiences that are planned, are also discussed. © 2015 IIMC.

Nowadays plagiarism is an interesting and debated topic in different fields. In music, the plagiarism is a very common phenomenon which touch the vast amounts of money that music melodies are able to generate in today's pop music market. In a music composition, the melody is assumed to be the most significant factor in a court's decision about whether a new music composition is an illegitimate version of a pre-existing composition. Despite the wide-spread belief that there is a fixed and trivial number of corresponding notes between two melodies, the similarity analysis is a very complex process. In this paper we address the plagiarism in pop music, and specifically, we study whether visualization can facilitate the task of discovering melodic similarities among musical songs. To investigate this, we defined three representations to show the melodic relations among songs. We performed a user study in which subjects performed different tasks on a song collection using these representations to investigate which one is best in terms of intuitiveness and accuracy. Results of the study provided us with positive feedback as well as further directions to explore. © 2016 IEEE.

Social Network Analysis and Mining | Year: 2016

In recent years, the encounter between network analysis (NA) and Law has issued new challenges both on a scientific and application level. If, on the one hand, it is fostering new computational-inspired approaches to visualize, retrieve, manipulate and analyze legal information, on the other hand, it is inspiring the creation of innovative tools allowing legal scholars without technical skills to start dealing with NA and visual analytics on their own. This paper presents an ongoing research project aiming to explore how approaches and techniques at the boundaries between Network analysis, Legal informatics and Visualization can help shedding new light into legal matters. The attention is focused, on EuCaseNet, an online toolkit allowing legal scholars to apply NA and visual analytics techniques to the entire corpus of EU case law. © 2016, Springer-Verlag Wien.

The consequences of angiopoietin-like protein 3 (ANGPTL3) deficiency on postprandial lipid and lipoprotein metabolism has not been investigated in humans. We studied 7 homozygous (undetectable circulating ANGPTL3 levels) and 31 heterozygous (50% of circulating ANGPTL3 levels) subjects with familial combined hypolipidemia (FHBL2) due to inactivating ANGPTL3 mutations in comparison with 35 controls. All subjects were evaluated at fasting and during 6 h after a high fat meal. Postprandial lipid and lipoprotein changes were quantified by calculating the areas under the curve (AUCs) using the 6 h concentration data. Plasma changes of ô-hydroxybutyric acid (ô-HBA) were measured as marker of hepatic oxidation of fatty acids. Compared with controls, homozygotes showed lower incremental AUCs (iAUCs) of total TG (ô69%, P < 0.001), TG-rich lipoproteins (ô90%, P < 0.001), apoB-48 (ô78%, P = 0.032), and larger absolute increase of FFA (128%, P < 00.1). Also, heterozygotes displayed attenuated postprandial lipemia, but the difference was significant only for the iAUC of apoB-48 (ô28%; P < 0.05). During the postprandial period, homozygotes, but not heterozygotes, showed a lower increase of ô-HBA. Our findings demonstrate that complete ANGPTL3 deficiency associates with highly reduced postprandial lipemia probably due to faster catabolism of intestinally derived lipoproteins, larger expansion of the postprandial FFA pool, and decreased influx of dietaryderived fatty acids into the liver. These results add information on mechanisms underlying hypolipidemia in FHBL2.-Minicocci, I., A. Tikka, E. Poggiogalle, J. Metso, A. Montali, F. Ceci, G. Labbadia, M. Fontana, A. Di Costanzo, M.

All subjects were evaluated at fasting and during 6 h after a high fat meal. Postprandial lipid and lipoprotein changes were quantified by calculating the areas under the curve (AUCs) using the 6 h concentration data. Plasma changes of -hydroxybutyric acid (-HBA) were measured as marker of hepatic oxidation of fatty acids. Compared with controls, homozygotes showed lower incremental AUCs (iAUCs) of total TG (-69%, P < 0.001), TG-rich lipoproteins (-90%, P < 0.001), apoB-48 (-78%, P = 0.032), and larger absolute increase of FFA (128%, P < 00.1).

During the postprandial period, homozygotes, but not heterozygotes, showed a lower increase of -HBA. Our findings demonstrate that complete ANGPTL3 deficiency associates with highly reduced postprandial lipemia probably due to faster catabolism of intestinally derived lipoproteins, larger expansion of the postprandial FFA pool, and decreased influx of dietary-derived fatty acids into the liver.
