Media activism on and off line by Italian adolescents and young adults

From several researchers it appears that Italian adolescents and young people are grown up with commercial television which is accused to contain too much violence, sex, reality shows, advertising, cartoons which are watched from 1 to 4 hours daily. Adolescents are also great users of mobile phones and spend a lot of time to use it. Their academic results are below the average of Ocse States. However the widespread use of communication technology and social networks display also another side of adolescents who engage in media activism and political movement such as Ammazzateci tutti!, Indymedia, Movimento 5 Stelle, Movimento No Tav. In which way does the world economic crisis -with the specific problems of Italy as the cutting founds for school, academic research and welfare, the corruption of political class, mafia and camorra organisation induce a reaction in our adolescents and young people? Several researches inform us about their use of internet in terms of spending time but, more important, how internet, and the web 2.0, could be an instrument for their reaction? What do they do online? How they do it? Which is the meaning of their presence online? And, has their online activity a continuity offline? The research aims are: 1. Trough a participant observation of Social Network profiles opened by 10 young active citizens, I would seek to understand which kind of social or political activities they engage in online as individuals and which is the meaning of their presence online. 2. To observe and understand if adolescents and young people have a continuity of their socio-political engagement online in offline activities and which kind of experiences it is. 3. Try to comprehend which was (or which were) the significant, learning experiences that convinced them about the potential of the web as tool for their activism.

Evolutionary genetics of lactase persistence in Eurasian human populations

Although ability to digest lactose generally declines after weaning in all mammals, in some human populations it persists also in adult individuals, a condition named lactase persistence (LP). Studies on the prevalence of the LP phenotype in worldwide human populations have shown that the frequency of this trait is highly variable in different ethnic groups, appearing to be positively correlated with the importance of milk in the diet. In particular, several single-nucleotide polymorphisms (SNPs) in the proximity of the LCT gene have been proved to be associated with LP. Nevertheless, few studies have till now analyzed genetic variation underlying LP in a wide set of Eurasian populations and, especially, in the Italian one. In the present study, we thus typed 40 SNPs surrounding the LCT gene in more than 1,000 samples from Italian and Arabic peninsulas to investigate patterns of LP-related genetic diversity in two regions which have played a pivotal role in the recent human evolutionary history according to their geographical position and historical/archaeological records. Our results underline a high and complex variability of the explored genomic region in both studied populations. In particular, a clear diversification of Northern Italian groups from the rest of the peninsula, was observed, with the formers being genetically more similar to Northern European populations than to Southern Italians. These observation are consistent with known decreasing pattern of LP from Northern to Southern Italy and suggest the possibility of an independent evolution of LP-associated genotypes in Northern Italy. A similar scenario was observed in the Arabian peninsula, with Dhofari Arabs from Southern Oman and Yemeni clustering together with respect to Arabs from Northern Oman and the subgroup of Omanis of Asian origin which appeared instead to be genetically closer to Europeans than to the rest of Arabic groups.

Using national FADN database to describe Italian farms and arable fields. A comparison of sustainability level between organic versus conventional regimes.

The study defines a new farm classification and identifies the arable land management. These aspects and several indicators are taken into account to estimate the sustainability level of farms, for organic and conventional regimes. The data source is Italian Farm Account Data Network (RICA) for years 2007-2011, which samples structural and economical information. An environmental data has been added to the previous one to better describe the farm context. The new farm classification describes holding by general informations and farm structure. The general information are: adopted regime and farm location in terms of administrative region, slope and phyto-climatic zone. The farm structures describe the presence of main productive processes and land covers, which are recorded by FADN database. The farms, grouped by homogeneous farm structure or farm typology, are evaluated in terms of sustainability. The farm model MAD has been used to estimate a list of indicators. They describe especially environmental and economical areas of sustainability. Finally arable lands are taken into account to identify arable land managements and crop rotations. Each arable land has been classified by crop pattern. Then crop rotation management has been analysed by spatial and temporal approaches. The analysis reports a high variability inside regimes. The farm structure influences indicators level more than regimes, and it is not always possible to compare the two regimes. However some differences between organic and conventional agriculture have been found. Organic farm structures report different frequency and geographical location than conventional ones. Also different connections among arable lands and farm structures have been identified.

I Fondi Strutturali europei 2007-2013 in Italia: un'analisi delle criticità

A 7 anni dall’avvio dell’ attuazione della Politica di Coesione dell’Unione Europea 2007- 2013, l’Italia ha il tasso di assorbimento dei Fondi Strutturali più basso d’Europa, insieme alla Romania, e rischia di subire un disimpegno delle risorse, che rappresenterebbe un gravissimo fallimento economico e politico. Il contributo di questo lavoro al dibattito sull’uso dei Fondi strutturali in Italia è duplice. Da una parte, per la prima volta, si propone uno studio sistematico delle criticità nella gestione del periodo 2007-2013, che hanno causato l’attuale ritardo nella spesa. Dall’altra, si affronta il problema italiano sia da una prospettiva europea sia nella sua dimensione nazionale, indagando le differenze regionali nella performance di spesa e proponendo un’analisi basata su tre dimensioni principali delle criticità: finanziaria, politica, amministrativa. L’approccio della ricerca consiste nella convergenza di dati quantitativi e qualitativi, raccolti durante un periodo di ricerca a Bruxelles e presso le Autorità di Gestione dei Programmi Operativi cofinanziati dal FESR. La questione dell’assorbimento finanziario e del ritardo nell’attuazione è stata indagata da tre punti di vista. Una prospettiva “storica”, che ha raccontato il ritardo strutturale nell’utilizzo dei Fondi Strutturali in Italia e che ha chiarito come il problema italiano, prima dell’attuale ciclo 2007-2013, sia stato non di quantità, ma di qualità della spesa. La seconda prospettiva è stata di respiro europeo, ed è servita a indagare le cause del basso livello di assorbimento finanziario dell’Italia suggerendo alcuni elementi utili a comprendere le ragioni di un simile divario con gli altri Paesi. Infine, la prospettiva nazionale e regionale ha svelato l’esistenza di un mix complesso, e micidiale, che ha letteralmente paralizzato la spesa italiana dei Fondi. Un mix di fattori finanziari, politici e amministrativi che non ha avuto eguali negli altri Paesi, e che si è concentrato soprattutto, ma non esclusivamente, nelle regioni dell’Obiettivo Convergenza.

Adulthood with Turner Syndrome: Quality of life, psychosocial adjustment and clinical management in 70 Italian women

Abstract Background: Turner syndrome (TS) is a chromosomal abnormality (total or partial absence of one of the sexual chromosomes in some or all cells of the body), which affects approximately 1:2000 female. Principal characteristics are short stature and gonadal disgenesis. Clinical management consist of Growth Hormone (GH) treatment and oestrogen replacement therapy (HRT), to induce development of secondary characteristics and to avoid the sequelae of oestrogen deficiency. Aim of the study: To assess clinical management, quality of life (QoL) and general psychosocial adjustment of women with TS. Population: 70 adult Caucasian females with TS (mean age: 27.8, ± 7.6; range 18-48 y.). Setting: Specialist service for Rare Disease care, University Hospital. Methods: Subjects were required to fill in questionnaires collecting ASR, WHOQOL, and 8 open questions. Data were compared with those of the Italian population or to those collected in a comparison group (70 healthy females, mean age: 27.9, ±7.3, range 21-48 y.). Results: Women with TS are educated as well as the Italian Population, but they have a less successful professional life. They show good QoL in general, but they appeared less satisfied in social area. They had statistically higher scores than the comparison group for depression, anxiety and withdrawal. Are less involved in a love relationship. Diagnosis communication was mostly performed by doctors or parents, satisfaction was higher when information was given by parents. Main preoccupation about TS are infertility, feeling of being different and future health problem. Conclusions: Italian people with TS were generally well adapted and have a good QoL, but lived more often with parents and show impaired sentimental and sexual life. They have higher degree of psychological distress compared to a comparison group. Psychological intervention should firstly address parents in order to encourage an open communication on diagnosis issues and on sexual education.

Evolutionary epigenetics of modern human populations

Epigenetic variability is a new mechanism for the study of human microevolution, because it creates both phenotypic diversity within an individual and within population. This mechanism constitutes an important reservoir for adaptation in response to new stimuli and recent studies have demonstrated that selective pressures shape not only the genetic code but also DNA methylation profiles. The aim of this thesis is the study of the role of DNA methylation changes in human adaptive processes, considering the Italian peninsula and macro-geographical areas. A whole-genome analysis of DNA methylation profile across the Italian penisula identified some genes whose methylation levels differ between individuals of different Italian districts (South, Centre and North of Italy). These genes are involved in nitrogen compound metabolism and genes involved in pathogens response. Considering individuals with different macro-geographical origins (individuals of Asians, European and African ancestry) more significant DMRs (differentially methylated regions) were identified and are located in genes involved in glucoronidation, in immune response as well as in cell comunication processes. A "profile" of each ancestry (African, Asian and European) was described. Moreover a deepen analysis of three candidate genes (KRTCAP3, MAD1L and BRSK2) in a cohort of individuals of different countries (Morocco, Nigeria, China and Philippines) living in Bologna, was performed in order to explore genetic and epigenetic diversity. Moreover this thesis have paved the way for the application of DNA methylation for the study of hystorical remains and in particular for the age-estimation of individuals starting from biological samples (such as teeth or blood). Noteworthy, a mathematical model that considered methylation values of DNA extracted from cementum and pulp of living individuals can estimate chronological age with high accuracy (median absolute difference between age estimated from DNA methylation and chronological age was 1.2 years).

Trait emotional intelligence: Evidence from italian adolescents and adults

Emotional intelligence (EI) represents an attribute of contemporary attractiveness for the scientific psychology community. Of particular interest for the present thesis are the conundrum related to the representation of this construct conceptualized as a trait (i.e., trait EI), which are in turn reflected in the current lack of agreement upon its constituent elements, posing significant challenges to research and clinical progress. Trait EI is defined as an umbrella personality-alike construct reflecting emotion-related dispositions and self-perceptions. The Trait Emotional Intelligence Questionnaire (TEIQue) was chosen as main measure, given its strong theoretical and psychometrical basis, including superior predictive validity when compared to other trait EI measures. Studies 1 and 2 aimed at validating the Italian 153-items forms of the TEIQue devoted to adolescents and adults. Analyses were done to investigate the structure of the questionnaire, its internal consistencies and gender differences at the facets, factor, and global level of both versions. Despite some low reliabilities, results from Studies 1 and 2 confirm the four-factor structure of the TEIQue. Study 3 investigated the utility of trait EI in a sample of adolescents over internalizing conditions (i.e., symptoms of anxiety and depression) and academic performance (grades at math and Italian language/literacy). Beyond trait EI, concurrent effects of demographic variables, higher order personality dimensions and non-verbal cognitive ability were controlled for. Study 4a and Study 4b addressed analogue research questions, through a meta-analysis and new data in on adults. In the latter case, effects of demographics, emotion regulation strategies, and the Big Five were controlled. Overall, these studies showed the incremental utility of the TEIQue in different domains beyond relevant predictors. Analyses performed at the level of the four-TEIQue factors consistently indicated that its predictive effects were mainly due to the factor Well-Being. Findings are discussed with reference to potential implication for theory and practice.

Studio del possibile ruolo del complesso polycomb nel determinare la schisi del labbro e del palato

La labioschisi con o senza palatoschisi non-sindromica (NSCL/P) è tra le più frequenti alterazioni dello sviluppo embrionale, causata dall’interazione di fattori genetici e ambientali, moti dei quali ancora ignoti. L'obiettivo del mio progetto di Dottorato consiste nell’identificazione di fattori di rischio genetico in un processo a due stadi che prevede la selezione di geni candidati e la verifica del loro coinvolgimento nella determinazione della malformazione mediante studi di associazione. Ho analizzato alcuni polimorfismi a singolo nucleotide (SNPs) dei geni RFC1 e DHFR, appartenenti alla via metabolica dell’acido folico, evidenziando una debole associazione tra alcuni degli SNPs indagati e la NSCL/P nella popolazione italiana. Presso il laboratorio della Dott.ssa Mangold dell’Università di Bonn, ho valutato il ruolo di 15 diverse regioni cromosomiche nel determinare la suscettibilità alla malattia, evidenziando una significativa associazione per i marcatori localizzati in 8q24 e 1p22. Ho quindi rivolto la mia attenzione al ruolo del complesso Polycomb nell’insorgenza della schisi. Nell’uomo i due complessi Polycomb, PRC1 e PRC2, rimodellano la cromatina agendo da regolatori dei meccanismi trascrizionali alla base della differenziazione cellulare e dello sviluppo embrionale. Ho ipotizzato che mutazioni a carico di geni appartenenti a PRC2 possano essere considerati potenziali fattori di rischio genetico nel determinare la NSCL/P. Il razionale consiste nel fatto che JARID2, una proteina che interagisce con PRC2, è associata all’insorgenza della NSCL/P ed espressa a livello delle cellule epiteliali delle lamine palatine che si approssimano alla fusione. L’indagine condotta analizzando i geni di elementi o partner dei due complessi Polycomb, ha evidenziato un’associazione significativa con alcuni polimorfismi dei geni indagati, associazione ulteriormente confermata dall’analisi degli aplotipi. Le analisi condotte sui geni candidati mi hanno permesso di raccogliere dati interessanti sull’eziologia della malformazione. Studi indipendenti saranno necessari per poter validare l'associazione tra le varianti genetiche di questi geni candidati e la NSCL/P.

Le Zone Franche Urbane: Mercato europeo e Ordinamenti tributari

Lo studio delle Zone Franche Urbane all’interno del Diritto tributario europeo non ha potuto prescindere da una introduttiva delimitazione del lavoro, capace di distinguere le diverse tipologie di zone franche esistenti nei Paesi intra/extra Ue. Attraversando i casi-studio di Madeira, delle Azzorre, fino alla istituenda Zona Franca di Bruxelles, Zone d’Economie Urbaine stimulée (ZEUS), si è giunti alla constatazione dell’assenza di una definizione di Zona Franca Urbana: analizzando le esperienze normative vissute in Francia e in Italia, si è potuto tratteggiare il profilo territoriale, soggettivo e oggettivo del sistema agevolativo rivolto al recupero delle aree urbane degradate. La funzione strumentale della fiscalità, esplicitata per mezzo delle ZFU, ha condotto ad una verifica di diritto interno per controllare la legittimità delle scelte nazionali in ragione dei principi costituzionali nazionali, come anche una di diritto europeo per evitare che le scelte nazionali, anche se legittime sul piano interno, possano per gli stessi effetti incentivanti alle attività d'impresa presentarsi come una forma territoriale di aiuti di Stato fiscali. Evidenziando il rapporto tra le ZFU e il Mercato europeo si è voluto, da un lato, effettuare una ricostruzione sistemica necessaria per un’interpretazione delle ZFU che metta in luce le componenti di tale strumento orientate al perseguimento di un interesse socioeconomico, che in prima battuta generi una contraddizione, una deroga ai principi costituzionali e comunitari, per poi “sciogliersi” in una coerente applicazione degli stessi; dall’altro, tentare di elevare le ZFU a misura sistemica dell’Ordinamento europeo. Si è svolto, infine, un ragionamento in termini di federalismo fiscale con riferimento alle ZFU, trovando una adeguata collocazione nel percorso di devoluzione intrapreso dal legislatore nazionale, avendo quali interlocutori privilegiati le Regioni a Statuto Speciale.
