Musica come Scienza dell'uomo. I caratteri del sapere musicale nel Settecento britannico

The departure point of the present work is the idea that in order to understand what music meant to British society in the Eighteenth-Century an interdisciplinary approach is necessary. Natural philosophy, moral philosophy, musical treatises and histories of music: all these sources concur both to the creation of a new idea about what music and its ‘science’ are, and to question the place which music ought to have in the realm of the Science of Man. The dissertation is divided into two sections. In the first one we will take into account philosophical sources (from John Locke, Joseph Addison and Lord Shaftesbury, to Lord Kames and Adam Smith), and we will examine their thoughts on music. In the second one we will deal with musical sources (from the Treatise of Musick of Alexander Malcom, to the Histories of Music of Charles Burney and John Hawkins) in order to show their connection with the philosophical literature before mentioned. The main aim of the work it to show that the development of specific philosophies of the human mind, such as the ones of John Locke and David Hume, did influence the way in which music was thought. Particularly we will point out the case of Adam Smith’s interpretation of instrumental music, which is heavily indebted to the humeian model of the human mind.

Studi ed approfondimenti sulla composizione in acidi grassi del latte bovino di razza Reggiana con diverso fenotipo per k-caseina e Beta-lactoglobulina

The aim of the present study was to examine the association between milk protein polymorphism and fatty acids profiles of bovine milk. Milk samples were collected from each of 55 Reggiana cows during early, mid and late lactation, respectively, in two farms within the production area of Parmigiano Reggiano cheese. Identification and quantification of fatty acids were performed by gas chromatography. Milk fatty acid composition using cows of differing κ-casein (κ-Cn) and β-lactoglobulin (β-Lg) phenotypes was investigated. Statistically significant results regarding the associations between milk fatty acid composition and κ-Cn phenotype were found, in particular, κ-Cn BB seems to influence de novo fatty acid synthesis in the mammary gland. Also κ-Cn AB seems to have the same effect. Proportions of C10:0 (2,29a AA; 2,53b AB; 2,59b BB), C12:0 (2,77a AA; 3,17b AB; 3,20b BB) and C14:0 (9,22a AA; 10,25b AB; 10,27b BB) were higher in the milk from cows with κ-Cn phenotype AB and BB vs κ-Cn phenotype AA (p<0,05). Conversely C18:0 (7,84b AA; 7,20a,b AB; 6,94a BB) and C18:1 (19,19b AA; 16,81a AB; 16,79a BB) were lower in the milk from cows with κ-Cn phenotype AB and BB vs κ-Cn phenotype AA. The association between milk fatty acid composition and β-Lg phenotype was not statistically significant, except for some fatty acids. In particular, C12:0 (3,05a AA; 3,04a AB; 3,33b BB) was higher in the milk from cows with β-Lg phenotype BB vs β-Lg phenotype AA and AB (p<0,05). Concentrations of C18:0 (6,93a AA; 7,86b AB; 6,59a BB) and C18:1 (16,74a,b AA; 18,24b AB; 16,07a BB) were lower in the milk from cows with β-Lg phenotype AA and BB vs β-Lg phenotype AB (p<0,05). Moreover this research, carried out in farms within the Parmigiano Reggiano cheese district, analysed also the size distribution of fat globules in bulk milk of Reggiana and Frisona breed cows. In particular, the size distribution of individual milk fat globules of Reggiana cows with differing κ-Cn phenotypes was considered. From first observations, no statistically significant differences were observed.

L'attrazione sessuale: processi psichici e strumenti di indagine. L'adattamento italiano del Cuestionario de Atraccion sexual

The sexual attraction is a complex emotional event, with somatic modifications, that like all the emotions, belongs to the psychic dimension and that, too much simply, can be led back, from a explicative point of view, to biological and psychical causes. The sexual attraction represents a personal experience, that is difficult to record, but of which every adult is able to delineate a correspondence with own “lived”. In the within of biological sciences, many experimental studies were been conducted with the aim to know which chemistries substances and cerebral zones are involved in front of a stimulus assessed like sexually attractive. Contrarily, there are little researches conducted in psychological field, aimed to the understanding the psychical factors, often unconscious, tinged to the subjective processes of sexual attraction: the sexual attraction remains an unexplored psychological event and unprovided of adapted instruments of assessment. The present thesis is oriented in primis to examine the existing scientific literature, in order to provide an exhaustive picture of the sexual attraction and to analyze the instruments of survey available for the empirical assessment of it. Secondly, the thesis is oriented to introduce two studies: the first study is aimed to adapt the Cuestionario de Atracción Sexual - CAS (Fernández ET to, 2006a; 2006b; 2006c) to the Italian language; the second study is aimed to assess the attitudes towards the sexual attraction in a sample of university students, in order to establish if some differences or association with some psychological dimensions (attachment stiles and alexithymia) exist.

Teorie e immagini del governo "misto" nel Cinquecento: i casi di Gasparo Contarini, Donato Giannotti, Paolo Paruta e Traiano Boccalini

This doctoral dissertation faces the debated topic of the traditions of Republicanism in the Modern Age assuming, as a point of view, the problem of the "mixed" government. The research therefore dwells upon the use of this model in Sixteenth-Century Italy, also in connection with the historical events of two standard Republics such as Florence and Venice. The work focuses on Donato Giannotti (1492-1573), Gasparo Contarini (1483-1542) and Paolo Paruta (1540-1598), as the main figures in order to reconstruct the debate on "mixed" constitution: in them, decisive in the attention paid to the peculiar structure of the Venetian Republic, the only of a certain dimension and power to survive after 1530. The research takes into account also the writings of Traiano Boccalini (1556-1613): he himself, though being involved in the same topics of debate, sets for some aspects his considerations in the framework of a new theme, that of Reason of State.

Il ruolo del collicolo superiore nell'orientamento spaziale

This thesis was aimed at verifying the role of the superior colliculus (SC) in human spatial orienting. To do so, subjects performed two experimental tasks that have been shown to involve SC’s activation in animals, that is a multisensory integration task (Experiment 1 and 2) and a visual target selection task (Experiment 3). To investigate this topic in humans, we took advantage of neurophysiological finding revealing that retinal S-cones do not send projections to the collicular and magnocellular pathway. In the Experiment 1, subjects performed a simple reaction-time task in which they were required to respond as quickly as possible to any sensory stimulus (visual, auditory or bimodal audio-visual). The visual stimulus could be an S-cone stimulus (invisible to the collicular and magnocellular pathway) or a long wavelength stimulus (visible to the SC). Results showed that when using S-cone stimuli, RTs distribution was simply explained by probability summation, indicating that the redundant auditory and visual channels are independent. Conversely, with red long-wavelength stimuli, visible to the SC, the RTs distribution was related to nonlinear neural summation, which constitutes evidence of integration of different sensory information. We also demonstrate that when AV stimuli were presented at fixation, so that the spatial orienting component of the task was reduced, neural summation was possible regardless of stimulus color. Together, these findings provide support for a pivotal role of the SC in mediating multisensory spatial integration in humans, when behavior involves spatial orienting responses. Since previous studies have shown an anatomical asymmetry of fibres projecting to the SC from the hemiretinas, the Experiment 2 was aimed at investigating temporo-nasal asymmetry in multisensory integration. To do so, subjects performed monocularly the same task shown in the Experiment 1. When spatially coincident audio-visual stimuli were visible to the SC (i.e. red stimuli), the RTE depended on a neural coactivation mechanism, suggesting an integration of multisensory information. When using stimuli invisible to the SC (i.e. purple stimuli), the RTE depended only on a simple statistical facilitation effect, in which the two sensory stimuli were processed by independent channels. Finally, we demonstrate that the multisensory integration effect was stronger for stimuli presented to the temporal hemifield than to the nasal hemifield. Taken together, these findings suggested that multisensory stimulation can be differentially effective depending on specific stimulus parameters. The Experiment 3 was aimed at verifying the role of the SC in target selection by using a color-oddity search task, comprising stimuli either visible or invisible to the collicular and magnocellular pathways. Subjects were required to make a saccade toward a target that could be presented alone or with three distractors of another color (either S-cone or long-wavelength). When using S-cone distractors, invisible to the SC, localization errors were similar to those observed in the distractor-free condition. Conversely, with long-wavelength distractors, visible to the SC, saccadic localization error and variability were significantly greater than in either the distractor-free condition or the S-cone distractors condition. Our results clearly indicate that the SC plays a direct role in visual target selection in humans. Overall, our results indicate that the SC plays an important role in mediating spatial orienting responses both when required covert (Experiments 1 and 2) and overt orienting (Experiment 3).

Nuove tecniche per l'allevamento massale di Ditteri del genere Coenosia Meigen

The species of the genus Coenosia Meigen are polyphagous predators both in the larval and in the adult stage. In Europe five Coenosia species of the ‘tigrina group’ are naturally present in greenhouses, where they can establish for long periods. As their wide preys range includes important pests of protected crops, as Aleyrodidae, Sciaridae and Agromyzidae, Coenosia species are considered promising potential biological control agents. A method for rearing Coenosia species in vivo was developed for the first time in 1993 in Germany, where C. attenuata, C. strigipes and C. humilis were bred on Bradysia paupera (Diptera Sciaridae), reared on Fusarium spp. cultivated on wood fibre. Although this method was partially simplified afterwards, it is still too complex and expensive for a mass production. This research aimed at simplifying this rearing procedure and making it cheaper, in the perspective of an eventual mass production. Studies on potential preys were conducted, to determine their suitability for C. attenuata larvae and adults and to develop rearing methods. Biology and rearing methods of Bradysia paupera Tuomikoski, Scatella stagnalis Fallén and Drosophila melanogaster Meigen (Diptera: Sciaridae, Ephydridae, Drosophilidae) were compared. B. paupera resulted the most suitable prey for rearing C. attenuata in vivo. The Sciarid fly was effectively reared on damp coconut fibre with fresh Agaricus bisporus (J.E. Lange) Pilát, thus simplifying the existing method. After preliminary trials with different potential preys, attempts to rear C. attenuata in vivo on B. paupera and D. melanogaster were made. The best results were obtained with B. paupera, reared on coconut fibre and A. bisporus, but the method needs further improvement. Trials of in vitro rearing of C. attenuata were also made: as no specific diet for Coenosia species is reported in literature, different potentially suitable media were tested. Among these, a specific diet for Diptera Tachinidae resulted a good starting point for further studies and improvements. The biology of C. attenuata adults captured in greenhouses was also studied, by observing both groups and isolated individuals. Data on lifespan, daily number of preys per adult, daily number of laid eggs and hatching rate were recorded, and the effects of different foods on these parameters were analyzed. The following foods were compared: D. melanogaster adults only, as preys for C. attenuata; D. melanogaster adults and a water-honey solution; the water-honey solution only. Honey resulted an effective food integration for C. attenuata, increasing lifespan and the number of egg laying females. It is possible that in greenhouses Coenosia adults complete the preys diet with nectar and/or honeydew. Moreover, the integration with honey reduced the daily preys consumption. This may allow to prevent cannibalism among Coenosia adults in the rearing conditions, where high population densities are required. A survey of the Coenosia species naturally present in Lombardy greenhouses was conducted. The species C. attenuata, C. strigipes, C. tigrina and C. atra were detected. C. attenuata resulted the most common, recorded in most greenhouses and for consecutive years. Besides, the presence of potential preys, weeds and the crops were recorded in each greenhouse. Nevertheless, it is difficult to determine the relation between these parameters and the presence of Coenosia species.

Rafael Moneo: la complessità del vuoto. Dalle matrici formali dell'opera di Oteiza e Chillida

The experience of void, essential to the production of forms and to make use them, can be considered as the base of the activities that attend to the formative processes. If void and matter constitutes the basic substances of architecture. Their role in the definition of form, the symbolic value and the constructive methods of it defines the quality of the space. This job inquires the character of space in the architecture of Moneo interpreting the meaning of the void in the Basque culture through the reading of the form matrices in the work of Jorge Oteiza and Eduardo Chillida. In the tie with the Basque culture a reading key is characterized by concurring to put in relation some of the theoretical principles expressed by Moneo on the relationship between place and time, in an unique and specific vision of the space. In the analysis of the process that determines the genesis of the architecture of Moneo emerges a trajectory whose direction is constructed on two pivos: on the one hand architecture like instrument of appropriation of the place, gushed from an acquaintance process who leans itself to the reading of the relations that define the place and of the resonances through which measuring it, on the other hand the architecture whose character is able to represent and to extend the time in which he is conceived, through the autonomy that is conferred to them from values. Following the trace characterized from this hypothesis, that is supported on the theories elaborated from Moneo, surveying deepens the reading of the principles that construct the sculptural work of Oteiza and Chillida, features from a search around the topic of the void and to its expression through the form. It is instrumental to the definition of a specific area that concurs to interpret the character of the space subtended to a vision of the place and the time, affine to the sensibility of Moneo and in some way not stranger to its cultural formation. The years of the academic formation, during which Moneo enters in contact with the Basque artistic culture, seem to be an important period in the birth of that knowledge that will leads him to the formulation of theories tied to the relationship between time, place and architecture. The values expressed through the experimental work of Oteiza and Chillida during years '50 are valid bases to the understanding of such relationships. In tracing a profile of the figures of Oteiza and Chillida, without the pretension that it is exhaustive for the reading of the complex historical period in which they are placed, but with the needs to put the work in a context, I want to be evidenced the important role carried out from the two artists from the Basque cultural area within which Moneo moves its first steps. The tie that approaches Moneo to the Basque culture following the personal trajectory of the formative experience interlaces to that one of important figures of the art and the Spanish architecture. One of the more meaningful relationships is born just during the years of his academic formation, from 1958 to the 1961, when he works like student in the professional office of the architect Francisco Sáenz de Oiza, who was teaching architectural design at the ETSAM. In these years many figures of Basque artists alternated at the professional office of Oiza that enjoys the important support of the manufacturer and maecenas Juan Huarte Beaumont, introduced to he from Oteiza. The tie between Huarte and Oteiza is solid and continuous in the years and it realizes in a contribution to many of the initiatives that makes of Oteiza a forwarder of the Basque culture. In the four years of collaboration with Oiza, Moneo has the opportunity to keep in contact with an atmosphere permeated by a constant search in the field of the plastic art and with figures directly connected to such atmosphere. It’s of a period of great intensity as in the production like in the promotion of the Basque art. The collective “Blanco y Negro”, than is held in 1959 at the Galería Darro to Madrid, is only one of the many times of an exhibition of the work of Oteiza and Chillida. The end of the Fifties is a period of international acknowledgment for Chillida that for Oteiza. The decade of the Fifties consecrates the hypotheses of a mythical past of the Basque people through the spread of the studies carried out in the antecedent years. The archaeological discoveries that join to a context already rich of signs of the prehistoric era, consolidate the knowledge of a strong cultural identity. Oteiza, like Chillida and other contemporary artists, believe in a cosmogonist conception belonging to the Basques, connected to their matriarchal mythological past. The void in its meaning of absence, in the Basque culture, thus as in various archaic and oriental religions, is equivalent to the spiritual fullness as essential condition to the revealing of essence. Retracing the archaic origins of the Basque culture emerges the deep meaning that the void assumes as key element in the religious interpretation of the passage from the life to the death. The symbology becomes rich of meaningful characters who derive from the fact that it is a chthonic cult. A representation of earth like place in which divine manifest itself but also like connection between divine and human, and this manipulation of the matter of which the earth it is composed is the tangible projection of the continuous search of the man towards God. The search of equilibrium between empty and full, that characterizes also the development of the form in architecture, in the Basque culture assumes therefore a peculiar value that returns like constant in great part of the plastic expressions, than in this context seem to be privileged regarding the other expressive forms. Oteiza and Chillida develop two original points of view in the representation of the void through the form. Both use of rigorous systems of rules sensitive to the physics principles and the characters of the matter. The last aim of the Oteiza’s construction is the void like limit of the knowledge, like border between known and unknown. It doesn’t means to reduce the sculptural object to an only allusive dimension because the void as physical and spiritual power is an active void, that possesses that value able to reveal the being through the trace of un-being. The void in its transcendental manifestation acts at the same time from universal and from particular, like in the atomic structure of the matter, in which on one side it constitutes the inner structure of every atom and on the other one it is necessary condition to the interaction between all the atoms. The void can be seen therefore as the action field that concurs the relations between the forms but is also the necessary condition to the same existence of the form. In the construction of Chillida the void represents that counterpart structuring the matter, inborn in it, the element in absence of which wouldn’t be variations neither distinctive characters to define the phenomenal variety of the world. The physics laws become the subject of the sculptural representation, the void are the instrument that concurs to catch up the equilibrium. Chillida dedicate himself to experience the space through the senses, to perceive of the qualities, to tell the physics laws which forge the matter in the form and the form arranges the places. From the artistic experience of the two sculptors they can be transposed, to the architectonic work of Moneo, those matrices on which they have constructed their original lyric expressions, where the void is absolute protagonist. An ambit is defined thus within which the matrices form them drafts from the work of Oteiza and Chillida can be traced in the definition of the process of birth and construction of the architecture of Moneo, but also in the relation that the architecture establishes with the place and in the time. The void becomes instrument to read the space constructed in its relationships that determine the proportions, rhythms, and relations. In this way the void concurs to interpret the architectonic space and to read the value of it, the quality of the spaces constructing it. This because it’s like an instrument of the composition, whose role is to maintain to the separation between the elements putting in evidence the field of relations. The void is that instrument that serves to characterize the elements that are with in the composition, related between each other, but distinguished. The meaning of the void therefore pushes the interpretation of the architectonic composition on the game of the relations between the elements that, independent and distinguished, strengthen themselves in their identity. On the one hand if void, as measurable reality, concurs all the dimensional changes quantifying the relationships between the parts, on the other hand its dialectic connotation concurs to search the equilibrium that regulated such variations. Equilibrium that therefore does not represent an obtained state applying criteria setting up from arbitrary rules but that depends from the intimate nature of the matter and its embodiment in the form. The production of a form, or a formal system that can be finalized to the construction of a building, is indissolubly tied to the technique that is based on the acquaintance of the formal vocation of the matter, and what it also can representing, meaning, expresses itself in characterizing the site. For Moneo, in fact, the space defined from the architecture is above all a site, because the essence of the site is based on the construction. When Moneo speaks about “birth of the idea of plan” like essential moment in the construction process of the architecture, it refers to a process whose complexity cannot be born other than from a deepened acquaintance of the site that leads to the comprehension of its specificity. Specificity arise from the infinite sum of relations, than for Moneo is the story of the oneness of a site, of its history, of the cultural identity and of the dimensional characters that that they are tied to it beyond that to the physical characteristics of the site. This vision is leaned to a solid made physical structure of perceptions, of distances, guideline and references that then make that the process is first of all acquaintance, appropriation. Appropriation that however does not happen for directed consequence because does not exist a relationship of cause and effect between place and architecture, thus as an univocal and exclusive way does not exist to arrive to a representation of an idea. An approach that, through the construction of the place where the architecture acquires its being, searches an expression of its sense of the truth. The proposal of a distinction for areas like space, matter, spirit and time, answering to the issues that scan the topics of the planning search of Moneo, concurs a more immediate reading of the systems subtended to the composition principles, through which is related the recurrent architectonic elements in its planning dictionary. From the dialectic between the opposites that is expressed in the duality of the form, through the definition of a complex element that can mediate between inside and outside as a real system of exchange, Moneo experiences the form development of the building deepening the relations that the volume establishes in the site. From time to time the invention of a system used to answer to the needs of the program and to resolve the dual character of the construction in an only gesture, involves a deep acquaintance of the professional practice. The technical aspect is the essential support to which the construction of the system is indissolubly tied. What therefore arouses interest is the search of the criteria and the way to construct that can reveal essential aspects of the being of the things. The constructive process demands, in fact, the acquaintance of the formative properties of the matter. Property from which the reflections gush on the relations that can be born around the architecture through the resonance produced from the forms. The void, in fact, through the form is in a position to constructing the site establishing a reciprocity relation. A reciprocity that is determined in the game between empty and full and of the forms between each other, regarding around, but also with regard to the subjective experience. The construction of a background used to amplify what is arranged on it and to clearly show the relations between the parts and at the same time able to tie itself with around opening the space of the vision, is a system that in the architecture of Moneo has one of its more effective applications in the use of the platform used like architectonic element. The spiritual force of this architectonic gesture is in the ability to define a place whose projecting intention is perceived and shared with who experience and has lived like some instrument to contact the cosmic forces, in a delicate process that lead to the equilibrium with them, but in completely physical way. The principles subtended to the construction of the form taken from the study of the void and the relations that it concurs, lead to express human values in the construction of the site. The validity of these principles however is tested from the time. The time is what Moneo considers as filter that every architecture is subordinate to and the survival of architecture, or any of its formal characters, reveals them the validity of the principles that have determined it. It manifests thus, in the tie between the spatial and spiritual dimension, between the material and the worldly dimension, the state of necessity that leads, in the construction of the architecture, to establish a contact with the forces of the universe and the intimate world, through a process that translate that necessity in elaboration of a formal system.
