La valutazione ex-post dei progetti integrati territoriali: un’analisi econometrica

2014

Questo lavoro tratta della valutazione di un programma di incentivi per lo sviluppo locale attuato nel sud dell’Italia durante l’ultimo decennio. Nel panorama degli strumenti di policy aventi l’obiettivo di ridurre le disparità territoriali e di promuovere lo sviluppo locale, i Progetti Integrati Territoriali (PIT) hanno rappresentato una peculiare modalità operativa di attuazione dei Programmi Operativi Regionali. Le risorse stanziate per ogni PIT potevano essere destinate a tre tipologie di intervento quali le infrastrutture, i regimi di aiuto e le azioni pubbliche. Di conseguenza sono possibili diversi approcci valutativi, a seconda degli obiettivi perseguiti da parte del valutatore. Att…

Learning Automata Based Q-learning for Content Placement in Cooperative Caching

2019

An optimization problem of content placement in cooperative caching is formulated, with the aim of maximizing sum mean opinion score (MOS) of mobile users. Firstly, a supervised feed-forward back-propagation connectionist model based neural network (SFBC-NN) is invoked for user mobility and content popularity prediction. More particularly, practical data collected from GPS-tracker app on smartphones is tackled to test the accuracy of mobility prediction. Then, a learning automata-based Q-learning (LAQL) algorithm for cooperative caching is proposed, in which learning automata (LA) is invoked for Q-learning to obtain an optimal action selection in a random and stationary environment. It is p…

Low-density-lipoproteins size and cardiovascular prevention

2005

Low-density lipoprotein (LDL) size appears to be an important predictor of cardiovascular events and progression of coronary artery disease, and the predominance of small, dense LDL has been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III. Yet, other authors have suggested that LDL subclass measurement does not add independent information to that conferred generically by LDL concentration and other standard risk factors. Therefore, the debate continues as to whether to measure LDL particle size for cardiovascular prevention and, if so, in which categories of patients. Since the therapeutic modulation of distinct LDL …

Factors affecting social integration and transversal skills of college students: a preliminary study

2015

International audience; This research, as a part of a PhD thesis in educational sciences relates to the social network and the transversal skills developed by the Bachelor's degree students ("Licence") in a French college. Overall, this work aims at identifying and estimating origins and effects of student social integration and transversal skills within the college careers. Four areas of student social integration and ten skills stemming from a reference table are measured by an original questionnaire. In this paper, the first preliminary results of this work are presented and reveal the influence of various personal and contextual factors on the integration and skills scores stated by stu…

Curative therapies are superior to standard of care (transarterial chemoembolization) for intermediate stage hepatocellular carcinoma.

2017

Background and aims the Barcelona Clinic Liver Cancer intermediate stage (BCLC-B) of hepatocellular carcinoma (HCC) includes extremely heterogeneous patients in terms of tumor burden and liver function. Transarterial-chemoembolization (TACE) is the first-line treatment for these patients although it may be risky/useless for someone, while others could undergo curative treatments. This study assesses the treatment type performed in a large cohort of BCLC-B patients and its outcome. Methods retrospective analysis of 485 consecutive BCLC-B patients from the ITA.LI.CA database diagnosed with naive HCC after 1999. Patients were stratified by treatment. Results 29 patients (6%) were lost to follo…

Treatment with metformin is associated with a prolonged survival in patients with hepatocellular carcinoma

2019

BACKGROUND Hepatocellular carcinoma (HCC) is one of the most lethal cancers. Nutrition- and life style-associated risk factors are increasingly prevalent. Metformin, the mainstay of type 2 diabetes mellitus (T2DM)-treatment, reduces the risk of hepatocarcinogenesis. However, its influence on the prognosis of patients with HCC has not been investigated on a large scale, yet. METHODS Five thousand and ninety-three patients treated for HCC between 2000 and 2016 at three referral centres were included in this retrospective multicentre study. The aim of this study was to assess whether treatment with metformin for T2DM is associated with a prolonged overall survival (OS) in patients diagnosed wi…

Testing the direct and moderator effects of the stressor-detachment model over one year : A latent change perspective

2018

ABSTRACTTo test the direct and moderator effects of the stressor–detachment model from a long-term perspective, we investigated whether workload and detachment are related to changes in exhaustion and sleep difficulties over one year. We also examined whether detachment attenuates the relationship between high workload and these outcomes both cross-sectionally and over time. Questionnaire data with 1722 respondents at Time 1 and 1182 respondents at Time 2 were collected. We used a latent change score approach to analyse the data in order to identify intra-individual change among the studied constructs. Our results showed that high workload and low detachment at baseline were related to an i…

Interval estimation for the breakpoint in segmented regression: a smoothed score-based approach

2017

Summary This paper is concerned with interval estimation for the breakpoint parameter in segmented regression. We present score-type confidence intervals derived from the score statistic itself and from the recently proposed gradient statistic. Due to lack of regularity conditions of the score, non-smoothness and non-monotonicity, naive application of the score-based statistics is unfeasible and we propose to exploit the smoothed score obtained via induced smoothing. We compare our proposals with the traditional methods based on the Wald and the likelihood ratio statistics via simulations and an analysis of a real dataset: results show that the smoothed score-like statistics perform in prac…

Automatic variable selection for exposure-driven propensity score matching with unmeasured confounders.

2020

Multivariable model building for propensity score modeling approaches is challenging. A common propensity score approach is exposure-driven propensity score matching, where the best model selection strategy is still unclear. In particular, the situation may require variable selection, while it is still unclear if variables included in the propensity score should be associated with the exposure and the outcome, with either the exposure or the outcome, with at least the exposure or with at least the outcome. Unmeasured confounders, complex correlation structures, and non-normal covariate distributions further complicate matters. We consider the performance of different modeling strategies in …
