Spatiality for formal topologies
2007
We define what it means for a formal topology to be spatial, and investigate properties related to spatiality both in general and in examples.
Diritti di partecipazione politica e piattaforme digitali, alcune riflessioni
2022
Questo scritto affronta il tema dell’impatto dei social networks sui diritti di partecipazione politica, con riguardo al diritto all’informazione, al diritto di associarsi in partiti, al diritto di voto come esito di campagne elettorali digitali. Il mutamento della comunicazione politica e del dibattito pubblico refluisce sulla correttezza dei processi democratici; ciò pone l’esigenza della regolazione dei social networks quale spazio mediatico utilizzato dai soggetti politici (individui od organizzazioni) per influenzare la formazione dell’opinione pubblica e costruire il consenso a proprio favore, soprattutto nell’ambito delle campagne elettorali. L’articolo si sofferma, dunque, sui probl…

В данный момент, на конец 2017 года, в Латвии, в соответствии с переносом действующих требований IV Директивы ПЛСПППФТ, уже проведен ряд изменений в нормативных актах ЛР, однако, часть правил еще следует ввести, в магистерской работе изучены возможности обеспечения полного переноса требований IV Директивы ПЛСПППФТ, а также совершенствования норм нормативных актов ЛР в соответствии с рекомендациями Группы разработки финансовых мер борьбы с отмыванием денег (FATF). Целью магистерской работы является проанализировать обязанность одного из субъектов права – кредитного учреждения – осуществлять изучение клиента, в рамках работы детально рассматривая и анализируя правовые аспекты изучения клиента…
Analysis of Pollutant Emissions on City Arteries—Aspects of Transport Management
2021
The aim of the study is to present a methodology for analyzing pollution emissions in a medium-sized city using modern traffic simulations in the aspect of minimizing exhaust emissions. The scope of the research and the methods of analysis used differ from those applied in big cities projects that can be found in the literature, Therefore the progressive elaboration model has been applied methodically to formulate and carry out the feasibility study. To perform microscopic traffic simulations, the software Simulation of Urban Mobility (SUMO—German Aerospace Center (DLR), Berlin, Germany) was applied. Thanks to the simulations, changes in traffic organization were accurately identified in th…
Biomonitoring of bisphenols A, F, S and parabens in urine of breastfeeding mothers: Exposure and risk assessment
2019
In the present study we used human biomonitoring to assess the internal exposure and the risk to four parabens and three bisphenols in 103 Spanish breastfeeding mothers participating in the BETTERMIILK project. Urinary methylparaben (MP), ethylparaben (EP), propylparaben (PP) and butylparaben (BP) presented detection frequencies ranging from 12% (BP) to 92% (MP), while bisphenol A (BPA), bisphenol F (BPF) and bisphenol S (BPS) were detected in 76% (BPA) and 20% (BPF, BPS) of the mothers. Average paraben concentrations (geometric mean) ranged from 0.021 ng mL(-1) (BP) to 17.7 ng mL(-1) (MP), whereas bisphenols had geometric means concentrations from 0.042 ng mL(-1) (BPF) to 0.927 ng mL(-1) (…

Forecasting the Size Premium Over Different Horizons
2011
In this paper, we provide evidence that the small stock premium is predictable both in-sample and out-of-sample through the use of a set of lagged macroeconomic variables. We find that it is possible to forecast the size premium over time horizons that range from one month to one year. We demonstrate that the predictability of the size premium allows a portfolio manager to generate an economically and statistically significant active alpha.
Selezione di Portafoglio e Metaeuristiche
2013
Il problema della selezione del portafoglio (PSP) ha come obiettivo quello di determinare, disponendo di un dato insieme di titoli, il portafoglio che minimizza una misura di rischio per un dato livello di rendimento minimo richiesto. Sebbene nella sua formulazione originaria il PSP può essere risolto utilizzando algoritmi di programmazione lineare o quadratica, l'inclusione di ulteriori vincoli ed obiettivi rende il problema computazionalmente difficile. Nel presente lavoro viene proposto un approccio metaeuristico al PSP in cui vengono considerate diverse misure di distanza tra i portafogli della frontiera efficiente (Mean-Variance) ed il portafoglio ottimo che si ottiene in corrispondenz…
Breastfeeding and COVID-19 vaccination: position statement of the Italian scientific societies
2021
AbstractThe availability of a COVID-19 vaccine has raised the issue of its compatibility with breastfeeding. Consequently, the Italian Society of Neonatology (SIN), the Italian Society of Pediatrics (SIP), the Italian Society of Perinatal Medicine (SIMP), the Italian Society of Obstetrics and Gynecology (SIGO), the Italian Association of Hospital Obstetricians-Gynecologists (AOGOI) and the Italian Society of Infectious and Tropical Diseases (SIMIT) have made an ad hoc consensus statement. Currently, knowledge regarding the administration of COVID-19 vaccine to the breastfeeding mother is limited. Nevertheless, as health benefits of breastfeeding are well demonstrated and since biological pl…
Position Statement on Breastfeeding from the Italian Pediatric Societies
2015
The 2015 Position Statement on Breastfeeding of The Italian Pediatric Societies (SIP, SIN, SICupp, SIGENP) recognizes breastfeeding as an healthy behaviour with many short and long term benefits for both mother and infant. While protecting, promoting and supporting breastfeeding, neonatologists and pediatricians need specific knowledge, skills and a positive attitude toward breastfeeding. In Maternity Hospitals and in Neonatal Units, appropriate organizative interventions should be applied in order to facilitate the beginning of breastfeeding and the use of mother’s/human milk. The Italian Pediatric Societies indicate the desiderable goal of around 6 months exclusive breastfeeding if the in…
