Association between osteoarthritis and social isolation: data from the EPOSA study
2019
Objective: To determine whether there is an association between osteoarthritis (OA) and incident social isolation using data from the European Project on OSteoArthritis (EPOSA) study.Design: Prospective, observational study with 12 to 18 months of follow-up.Setting: Community dwelling.Participants: Older people living in six European countries.Measurements: Social isolation was assessed using the Lubben Social Network Scale and the Maastricht Social Participation Profile. Clinical OA of the hip, knee, and hand was assessed according to American College of Rheumatology criteria. Demographic characteristics, including age, sex, multijoint pain, and medical comorbidities, were assessed.Results…
Global age-sex-specific fertility, mortality, healthy life expectancy (HALE), and population estimates in 204 countries and territories, 1950–2019: a…
2020
Background Accurate and up-to-date assessment of demographic metrics is crucial for understanding a wide range of social, economic, and public health issues that affect populations worldwide. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 produced updated and comprehensive demographic assessments of the key indicators of fertility, mortality, migration, and population for 204 countries and territories and selected subnational locations from 1950 to 2019. Methods 8078 country-years of vital registration and sample registration data, 938 surveys, 349 censuses, and 238 other sources were identified and used to estimate age-specific fertility. Spatiotemporal Gaussian…
Le stragi, Cosa nostra e la forbice sociale
2020
Oltre che per la sua soggettività politica, Cosa Nostra si è distinta nel tempo per la sua complessa pervasività sistemica, per la sua capacità di sfruttare le “intersezioni” tra dimensioni criminali e economia legale e per la duttile capacità di adattamento ai “vincoli di contesto” che, via via, le si sono presentati. Per comprenderne, quindi, l’attuale configurazione, occorre partire da tale complessità, senza appiattirne la storia in una “notte nera” dove “tutte le mafie sono uguali”, ma valorizzando le sue dimensioni identitarie, radicate su fatti, eventi e intersezioni assolutamente unici. Limitando l’attenzione all’ultimo trentennio, punto di osservazione privilegiato sono le stragi d…
On the stability analysis for impulsive switching system with time-varying delay
2014
This paper focuses on the stability and stabilization problem for a neutral impulsive switching system with time-varying delay. Based on LMI method and optimization technologies, some stability criteria are derived for this kind of system. Some example and numerical simulation are given to demonstrate the effectiveness of our theoretical results. Refereed/Peer-reviewed
Confidence Intervals for the Mean Based on Exponential Type Inequalities and Empirical Likelihood
2013
For independent observations, recently, it has been proposed to construct the confidence intervals for the mean using exponential type inequalities. Although this method requires much weaker assumptions than those required by the classical methods, the resulting intervals are usually too large. Still in special cases, one can find some advantage of using bounded and unbounded Bernstein inequalities. In this paper, we discuss the applicability of this approach for dependent data. Moreover, we propose to use the empirical likelihood method both in the case of independent and dependent observations for inference regarding the mean. The advantage of empirical likelihood is its Bartlett correcta…
Robust control of uncertain multi-inventory systems via linear matrix inequality
2008
We consider a continuous time linear multi inventory system with unknown demands bounded within ellipsoids and controls bounded within ellipsoids or polytopes. We address the problem of "-stabilizing the inventory since this implies some reduction of the inventory costs. The main results are certain conditions under which "-stabilizability is possible through a saturated linear state feedback control. All the results are based on a Linear Matrix Inequalities (LMIs) approach and on some recent techniques for the modeling and analysis of polytopic systems with saturations.
In between the inequalities of Sobolev and Hardy
2016
We establish both sufficient and necessary conditions for the validity of the so-called Hardy–Sobolev inequalities on open sets of the Euclidean space. These inequalities form a natural interpolating scale between the (weighted) Sobolev inequalities and the (weighted) Hardy inequalities. The Assouad dimension of the complement of the open set turns out to play an important role in both sufficient and necessary conditions. peerReviewed
Sharp generalized Trudinger inequalities via truncation
2006
Abstract We prove that the generalized Trudinger inequalities into exponential and double exponential Orlicz spaces improve to inequalities on Orlicz–Lorentz spaces provided they are stable under truncation.
Measuring Excellence and Equity in Education : Conceptual and Methodological Issues
2011
The text focuses on the measurement problems both equity and excellence does imply, and on the "technical" choices that are to be made. It aims at showing that those choices are not neutral and have plenty of political consequences. Starting with the problems of definition of both excellence and equity, which should be considered jointly, the paper examines i) how the indicators and methods implemented do have some impact on the amount of inequalities, and ii) on the necessity of a time dimension to figure out how inequalities are generated, along with a system-wide perspective.
The Impact of Internet and Social Media Use on Well-Being
2021
The present research examines the longitudinal average impact of frequency of use of Internet and social networking sites (SNS) on subjective well-being of adolescents in Germany. Based on five-wave panel data that cover a period of nine years, we disentangle between-person and within-person effects of media use on depressive symptomatology and life satisfaction as indicators of subjective well-being. Additionally, we control for confounders such as TV use, self-esteem, and satisfaction with friends. We found that frequency of Internet use in general and use of SNS in particular is not substantially related subjective well-being. The explanatory power of general Internet use or SNS use to p…
