Obbedienza e disobbedienza: dinamiche psicosociali per la democraziaMorselli, Davide <1976> 16 February 2009 (has links)
Questa ricerca parte dall’approccio dialogico alle rappresentazioni sociali proposto da Marková (2003), assumendo che obbedienza e disobbedienza sono entrambe costituite da dimensioni socialmente costruttive e distruttive e che la loro interazione si riflette sugli atteggiamenti verso la democrazia. L’ipotesi principale è quella che obbedienza e disobbedienza non si escludano a
vicenda, bensì che un’interazione bilanciata tra atteggiamenti favorevoli verso sia l’obbedienza sia
la disobbedienza possa promuovere atteggiamenti prodemocratici a livello individuale e un incremento della democrazia a livello societale, come suggerito anche dalle teorie politologiche di Dahl (1999).
La ricerca è stata sviluppata in due studi. Il primo è rappresentato da un’analisi cross-culturale condotta su dati provenienti dal World Values Survey ed è suddiviso in tre sottostudi: il primo indaga il rapporto tra la disobbedienza, le dimensioni distruttiva e costruttiva dell’obbedienza e gli atteggiamenti nei confronti della democrazia; il secondo si centra sulle differenze tra le due
dimensioni opposte della disobbedienza (costruttiva e distruttiva), mettendo in evidenza come alcuni aspetti della disobbedienza siano legati ad atteggiamenti prodemocratici; il terzo si occupa, invece, di indagare a livello societale gli effetti della diffusione della disobbedienza costruttiva sul livello di democrazia di una nazione, mettendo in evidenza che, sotto determinate circostanze, la disobbedienza può essere intesa come un fattore protettivo per la democrazia.
Il secondo studio si basa su un’inchiesta tramite questionari somministrati ad un campione di studenti universitari delle Università di Bologna ed Helsinki. Questo studio ha avuto la finalità di approfondire, da un punto di vista delle rappresentazioni sociali, come la dinamica tra obbedienza e disobbedienza si intrecci agli atteggiamenti verso la democrazia e verso l’assunzione di
responsabilità nei confronti della società. I risultati suggeriscono che obbedienza e disobbedienza siano in rapporto di complementarietà, e non di reciproca esclusione, integrandosi l’una con l’altra in maniera disgiunta (Lefkowitz, 2007): laddove l’obbedienza rappresenta un atteggiamento responsabile nei confronti della società e di tutte le sue parti costitutive, la disobbedienza è uno strumento di controllo e azione politica nei confronti dell’autorità. Inoltre a livello societale i risultati mostrano che laddove le disobbedienza
costruttiva si diffonde in una società, successivamente aumenta il suo livello di democrazia o, perlomeno, non diminuisce. Ciò suggerisce che la diffusione di una disobbedienza che coinvolge anche gli aspetti costruttivi dell’obbedienza possa rappresentare un fattore protettivo nei confronti della democraticità delle istituzioni e delle libertà politiche e civili.

Fundamental Dimensions of Social Judgment: Sociability and Morality as Distinct Characteristics of Social WarmthBrambilla, Marco <1980> 30 April 2010 (has links)
The present dissertation focuses on the two basic dimensions of social judgment, i.e., warmth and competence. Previous research has shown that warmth and competence emerge as fundamental dimensions both at the interpersonal level and at the group level. Moreover, warmth judgments appear to be primary, reflecting the importance of first assessing others’ intentions before determining the other’s ability to carry out those intentions. Finally, it has been shown that warmth and competence judgments are predicted by perceived economic competition and status, respectively (for a review, see Cuddy, Fiske, & Glick, 2008). Building on this evidence, the present work intends to further explore the role of warmth and competence in social judgment, adopting a finer-grained level of analysis. Specifically, we consider warmth to be a dimension of evaluation that encompasses two distinct characteristics (i.e., sociability and morality) rather than as an undifferentiated dimension (see Leach, Ellemers, & Barreto, 2007). In a similar vein, both economic competition and symbolic competition are taken into account (see Stephan, Ybarra, & Morrison, 2009). In order to highlight the relevance of our empirical research, the first chapter reviews the literature in social psychology that has studied the warmth and competence dimensions. In the second chapter, across two studies, we examine the role of realistic and symbolic threats (akin economic and symbolic competition, respectively) in predicting the perception of sociability and morality of social groups. In study 1, we measure perceived realistic threat, symbolic threat, sociability, and morality with respect to 8 social groups. In study 2, we manipulate the level and type of threat of a fictitious group and measure perceived sociability and morality. The findings show that realistic threat and symbolic threat are differentially related to the sociability and morality components of warmth. Specifically, whereas realistic threat seems to be a stronger predictor of sociability than symbolic threat, symbolic threat emerges as better predictor of morality than realistic threat. Thus, extending prior research, we show that the types of threat are linked to different warmth stereotypes. In the third and the fourth chapter, we examine whether the sociability and morality components of warmth play distinct roles at different stages of group impression formation. More specifically, the third chapter focuses on the information-gathering process. Two studies experimentally investigate which traits are mostly selected when forming impressions about either ingroup or outgroup members. The results clearly show that perceivers are more interested in obtaining information about morality than about sociability when asked to form a global impression about others. The fourth chapter considers more properly the formulation of an evaluative impression. Thus, in the first study participants rate real groups on sociability, morality, and competence. In the second study, participants read an immigration scenario depicting an unfamiliar social group in terms of high (vs. low) morality, sociability, and competence. In both studies, participants are also asked to report their global impression of the group. The results show that global evaluations are better predicted by morality than by sociability and competence trait ascriptions. Taken together the third and the fourth chapters show that the dominance of warmth suggested by previous studies on impression formation might be better explained in terms of a greater effect of one of the two subcomponents (i.e., morality) over the other (i.e., sociability). In the general discussion, we discuss the relevance of our findings for intergroup relation and group perception, as well as for impression formation.

La hija de Cervantes: un dramma romantico inedito di Aureliano Fernández-Guerra y Orbe. Edizione critica e studioRioli, Silvia <1982> 07 June 2011 (has links)
Aureliano Fernandez-Guerra is known especially among Quevedo’s scholars because he published the first complete edition of Quevedo’s works. Few people know his plays and, for this reason, they have never been studied. These plays were written during his youth, when Fernández-Guerra hadn’t decided anything about his career yet. Therefore, these plays were always very important for him and, for this reason, he continued to correct and to revise them. Among them, the unpublished drama La hija de Cervantes (1840) was considered the most important play.
In this doctoral thesis I have tried to describe this Spanish author, especially focusing on theatre. In the first part I wrote about the life and the literary works, giving particularly importance to his plays that are La peña de los enamorados (1939), La hija de Cervantes (1840), Alonso Cano (1842) and La Ricahembra (1845), this last one written in collaboration with Manuel Tamayo y Baus, another important and famous playwright.
In the second part I deepened the study of La hija de Cervantes because it is a particular interesting drama: Aureliano Fernández-Guerra chose to represent the author of the Quixote as a character of his drama, especially dramatizing the most mysterious moments of his life, such as the Gaspar de Ezpeleta’s murder, his relationship with his daughter Isabel de Saavedra and his supposed love for a woman, whose existence his unknown. Besides, this drama is interesting because it is partially autobiographic: I found several letters and articles where it is emphasized the similarities between Cervantes’ and Aureliano’s life: both feel misunderstood and not appreciated by other people and both had to renounce a big love.
In the final part I presented the critical edition of La hija de Cervantes based on the last three manuscripts that are today at the Institut de Teatre in Barcelona. A wide philological note shows the transcription criterions.

Gli esiti scolastici nelle scuole di secondo grado di Bologna: un'applicazione della teoria dei modelli a curva latenteBorgia, Maria Serena <1972> 08 April 2011 (has links)
Nella presente analisi si è avuta l’eccezionale disponibilità di dati longitudinali su molti individui (6000studenti frequentanti le scuole superiori bolognesi).
Per ottenere un modello che al meglio spiegasse e riproducesse l’andamento degli esiti scolastici (promozione alla classe successiva) tenendo conto del percorso scolastico nel tempo, si è scelto il modello a curva latente condizionato. La variabile risposta è combinazione lineare dell’esito di fine anno (Promosso/Non promosso); riassume, per ogni studente/anno scolastico, classe frequentata ed esito finale. Le variabili esplicative sono state selezionate tra le informazioni disponibili per gli individui.
Vengono presentati alcuni dati aggregati, poi descritti i dati individuali che entreranno nel modello, evidenziando la composizione degli studenti.
La prima fase è la stima del modello logistico, con specificazione delle criticità, che hanno indotto alla scelta successiva del modello dipendente dal tempo.
Dopo la descrizione della metodologia principale utilizzata, la teoria del conditionalLCM, e la selezione degli indicatori di fitting, viene delineata la procedura di stima, e raggiunto il modello ottimale.
Le variabili significative per spiegare l’andamento delle promozioni individuali nel tempo risultano: cittadinanza (italiani con risultati significativamente migliori degli stranieri), sesso (ragazze con percorso scolastico mediamente migliore dei ragazzi: la differenza risulta però significativa soltanto negli istituti tecnici e professionali), tipologia di scuola frequentata (studenti del liceo con risultati significativamente migliori di chi frequenta altri tipi di istituto).
I risultati risultano fortemente dipendenti dai dati impiegati, specie riguardo al limite territoriale. Precedenti analisi evidenziavano una forte differenziazione dei risultati scolastici tra studenti del nord e del sud Italia, oltre che tra studenti dei comuni maggiormente popolati e studenti dei comuni di provincia. Sarebbe interessante disporre di dati individuali analoghi a quelli qui utilizzati, ma riferiti all’intero territorio nazionale, oppure ad un zona maggiormente vasta dell’Italia, onde saggiare l’entità dell’influenza sul percorso scolastico,ed in particolare sulla regolarità, della differenza territoriale.

Novel techniques for the remote sensing of photosynthetic processesDayyoub, Ammar <1973> 12 April 2011 (has links)
Remote sensing (RS) techniques have evolved into an important instrument to investigate forest function. New methods based on the remote detection of leaf biochemistry and photosynthesis are being developed and applied in pilot studies from airborne and satellite platforms (PRI, solar-induced fluorescence; N and chlorophyll content).
Non-destructive monitoring methods, a direct application of RS studies, are also proving increasingly attractive for the determination of stress conditions or nutrient deficiencies not only in research but also in agronomy, horticulture and urban forestry (proximal RS).
In this work I will focus on some novel techniques recently developed for the estimation of photochemistry and photosynthetic rates based (i) on the proximal measurement of steady-state chlorophyll fluorescence yield, or (ii) the remote sensing of changes in hyperspectral leaf reflectance, associated to xanthophyll de-epoxydation and energy partitioning, which is closely coupled to leaf photochemistry and photosynthesis. I will also present and describe a mathematical model of leaf steady-state fluorescence and photosynthesis recently developed in our group. Two different species were used in the experiments: Arbutus unedo, a schlerophyllous Mediterranean species, and Populus euroamericana, a broad leaf deciduous tree widely used in plantation forestry.
Results show that ambient fluorescence could provide a useful tool for testing photosynthetic processes from a distance. These results confirm also the photosynthetic reflectance index (PRI) as an efficient remote sensing reflectance index estimating short-term changes in photochemical efficiency as well as long-term changes in leaf biochemistry.
The study also demonstrated that RS techniques could provide a fast and reliable method to estimate photosynthetic pigment content and total nitrogen, beside assessing the state of photochemical process in our plants’ leaves in the field. This could have important practical applications for the management of plant cultivation systems, for the estimation of the nutrient requirements of our plants for optimal growth.

'Defending the rights'. An integrated model of collective action for "public water" in ItalyMazzoni, Davide 09 March 2012 (has links)
In many communities, supplying water for the people is a huge task and the fact that this essential service can be carried out by the private sector respecting the right to water, is a debated issue. This dissertation investigates the mechanisms through which a 'perceived rights violation' - which represents a specific form of perceived injustice which derives from the violation of absolute moral principles – can promote collective action. Indeed, literature on morality and collective action suggests that even if many people apparently sustain high moral principles (like human rights), only a minority decides to act in order to defend them. Taking advantage of the political situation in Italy, and the recent mobilization for "public water" we hypothesized that, because of its "sacred value", the perceived violation of the right to water facilitates identification with the social movement and activism. Through five studies adopting qualitative and quantitative methods, we confirmed our hypotheses demonstrating that the perceived violation of the right to water can sustain activism and it can influence vote intentions at the referendum for 'public water'. This path to collective action coexists with other 'classical' predictors of collective action, like instrumental factors (personal advantages, efficacy beliefs) and anger. The perceived rights violation can derive both from personal values (i.e. universalism) and external factors (i.e. a mobilization campaign). Furthermore, we demonstrated that it is possible to enhance the perceived violation of the right to water and anger through a specifically designed communication campaign. The final chapter summarizes the main findings and discusses the results, suggesting some innovative line of research for collective action literature.
