Sociologia dell'inavvertito
No full textIn modo più o meno consapevole, la riflessione sociologica si è prevalentemente orientata verso lo studio degli aspetti insoliti, notevoli e particolari della realtà sociale, privilegiando l’analisi dei fatti popolarmente percepiti come degni d’interesse e categorizzati come tali già a livello di senso comune. Così, la disciplina ha spesso finito per ratificare i meccanismi di salienza convenzionali, riaffermando gli schemi cognitivi e i modelli culturali più diffusi. Muovendo da simili constatazioni, Brekhus argomenta l’efficacia di una diversa prospettiva sociologica, che distingua con chiarezza l’importanza analitica di un fenomeno dal rilievo che può essergli generalmente accordato. Combinando teoria e metodologia sociologiche e rileggendo criticamente autori classici come Goffman e Garfinkel, Brekhus pone le basi per una vera e propria sociologia dell’inavvertito, di cui vengono delineati i fondamenti epistemologici e le strategie procedurali.

Times of Sociology. Eviatar Zerubavel in Conversation with Lorenzo Sabetta
Full text linkThis interview offers a historical reconstruction of Eviatar Zerubavel’s work, from his pioneering studies of time to his not-yet-published analysis of “concept-driven sociology”, running the gamut of Zerubavel’s career and embracing a period of more than forty years of sociological research. The interview encompasses several major topics: the beginnings of Zerubavel’s own intellectual path and his move from Israel to the United States; the nuts and bolts of sociology of time and cognitive sociology; the underlying theoretical framework of a transcontextual and comparative mode of social inquiry; an in-depth analysis of the last books which Zerubavel has devoted to the study of phenomena such as backgroundness and taken-for-grantedness; the range of his academic and intellectual relationships (especially the one with his mentor Goffman, but also his rapport with Peter Berger, Lewis Coser, Renée Fox, and Murray Davis, among others); the polymorphic connection between sociological theory and politics; the development of the so-called “Rutgers School of Sociology”; the issue of “public sociology”; the future of sociology and academic research
Towards a new reference ground motion prediction equation for Italy: update of the Sabetta–Pugliese (1996)
No full textA revised Italian strong motion archive has become available since July 2007,
including all the records of the strongest events occurred from 1972 to 2004. It contains
the uncorrected and corrected accelerograms and the metadata relevant to seismic events,
recording stations and instruments added after a careful revision. The availability of this
archive allowed us to perform a first step towards an update of the reference ground motion
prediction equations for Italy, which were evaluated by Sabetta and Pugliese in (Bull Seismol
Soc Am 77:1491–1513, 1987), for peak ground acceleration and velocity, and subsequently
extended to the 5% damped pseudovelocity response spectra in 1996. A subset with the 27
major earthquakes occurred in Italy from 1972 to 2002, in the magnitude range 4.6–6.9,
was extracted and 235 good quality waveforms were selected, recorded at distances up to
183 km. The goodness of fit of the Sabetta and Pugliese (Bull Seismol Soc Am 86:337–352,
1996) model was explored using two independent statistical approaches (Spudich et al. Bull
Seismol Soc Am 89:1156–1170, 1999 and Scherbaum et al. Bull Seismol Soc Am 94:2164–
2185, 2004). The results obtained show that the Sabetta and Pugliese (Bull Seismol Soc Am
77:1491–1513, 1987) does not adequately fit the new strong-motion data set, for its small
standard deviation and its non-zero bias. In particular, the most noteworthy result is that the
Sabetta and Pugliese (Bull Seismol Soc Am 77:1491–1513, 1987) over-predicts peak ground
acceleration and velocity at rock sites. New coefficients for the prediction of horizontal peak
ground acceleration, peak ground velocity and acceleration response spectra, adopting the
same functional form in Sabetta and Pugliese (Bull Seismol Soc Am 77:1491–1513, 1987),
were then evaluated in order to fit the new data set. This paper illustrates the steps made to
update the existing ground motion prediction equations for Italy, discusses their limitations
and provides the basis for future developments.Published591–6084.1. Metodologie sismologiche per l'ingegneria sismicaJCR Journalreserve
Verso una congiunzione funzionale delle due “etiche” weberiane
No full textMaurizio Bonolis e Lorenzo Sabetta
Toward a Functional Alignment of Weber's “two ethics”
In the final pages of his Politik als Beruf, Max Weber introduced his now widely known and cited distinction between two types of ethics, i.e. the seemingly dichotomous relationship between the “ethics of conviction” (gesinnungsethik) and the “ethics of responsibility” (verantwortungsethik). This proposal has provoked widespread reaction, strong endorsement and quite favorable comments as well as a significant amount of criticism. The purpose of this article, however, is exactly to avoid such hypostatized interpretations of Weber’s work, trying instead to envision a sort of functional integration of the two kinds of ethics, making the case for a blurred and nuanced reading of this famous socio-political pair of concepts. Under this light, Weber’s distinction is best understood as a differentiation between analytical models and not ontological entities – actually, the two ethics seem to be inexorably intertwined with one another, in a constant play of juxtapositions and mutual cross-references
Le forme della cultura implicita: il caso dei “fatti sociali indicibili”
No full textLa ricerca sociologica ha prestato un’attenzione discontinua ma anche, alle volte, profonda e penetrante a tutto ciò che c’è d’inconsapevole, inarticolato, sottinteso e non immediatamente messo a fuoco nella realtà sociale.
Riepilogare le diverse declinazioni che quest’angolazione analitica ha assunto significa ripercorrere alcuni punti di particolare originalità contenutistica della teoria sociologica secondo-novecentesca e contemporanea. Fra gli altri, a titolo non esaustivo, si possono menzionare il dominio del «latente» nell’approccio struttural-funzionalista (Parsons, 1961; Merton, 1968; tr. it. 2000), il «visto-ma-inosservato» nell’etnometodologia (Garfinkel, 1967), il «silenzio» nell’analisi della conversazione (Sacks, 1992), l’«abitudinario» e l’«incorporato» nella teoria della pratica (Bourdieu, 1980; tr. it. 2005; Wacquant, 2000; tr. it. 2009), i «periodi stabili» nella teoria della cultura come cassetta degli attrezzi (Swidler, 1986), il «dato per scontato» e l’«inavvertito» nella sociologia cultural-cognitivista (Zerubavel, 1997; tr. it. 2022; Brekhus, 1998; tr. it. 2018), il «sistema 1» nella teoria dei processi duali (Vaisey, 2009), la sfera del «tacito» nelle sue ultime rivisitazioni sociologiche (Tur
ner, 2014). È significativo che proprio lo studio delle forme della cultura implicita sia giunto a rappresentare, nell’attuale panorama statunitense, il nodo per eccellenza del rapporto fra “culture and cognition”, fra modelli
culturali e schemi cognitivi. Il dibattito sul punto, peraltro acceso, è ancora in corso e quindi arduo da districare e valutare (si vedano, ad es., Lizardo, 2014; Lizardo et al., 2016; Brekhus e Ignatow, 2019; Martin e Lembo, 2020; Cerulo, Leschziner e Shepherd, 2021; Vaisey, 2021). Pure, non è difficile capire perché il tema della cultura implicita sia tornato a rappresentare una delle frontiere più promettenti della teoria sociale. Orientarsi euristicamente in questa direzione, infatti, comporta (-) affrontare elementi statisticamente prevalenti, a cui gli attori sono giocoforza più esposti (il numero di cose esprimibili è sempre minore di quelle che restano tacitamente sullo sfondo: cfr. Brekhus, 1998; tr. it. 2018; Bearman, 2005, p. 3); (-) provare a spiegare
l’inerzia e la stabilità, generalmente sottovalutate a favore dell’analisi del mutamento (cfr. Brekhus, in corso di pubblicazione); (-) esaminare i processi di socializzazione e inculturazione nel loro funzionamento normale, apparentemente naturale (cfr. Zerubavel, 2015; Zerubavel, 2018; tr. it. 2019); (-) vincolare la ricerca sociale a una certa misura di originalità analitica, tanto in senso teorico che metodologico (Sabetta, 2020); (-) ridare mordente all’attitudine disvelante che ha storicamente improntato le scienze sociali, la
loro tensione verso lo smascheramento (Baehr, 2019; Sica, 2020). Bontà e realizzabilità di questa serie di promesse verranno soppesate solo in parte in questa sede. Piuttosto, l’obiettivo del saggio è esaminare un caso
particolare delle forme della cultura implicita: quelle che si presentano come costitutivamente tali, la cui articolazione dichiarata e manifesta, cioè, è impossibile (o possibile a patto di far cambiar loro radicalmente forma) al livello dell’azione. Considerata l’attuale, diffusa enfasi su controllo e trasparenza nei campi sociali più disparati, la stessa esistenza di tali sacche di necessaria opacità può sembrare controintuitiva o sospetta; è allora proprio da questo punto che può essere conveniente partire
Transition Between Open and Closed Wake in 3D Linear Aerospike Nozzles
No full textLinear aerospike nozzles are envisaged as a possible device able to improve launcher engine performance. One of the most interesting properties of these nozzles is the possibility of a good integration with the vehicle. Tb improve the knowledge of the flow-field and performance of aerospike nozzles, they are studied numerically, with particular attention to the differences between the basic two-dimensional nozzle, usually considered in the design phase, and the more realistic three-dimensional nozzle. The study considers different plug lengths and ambient pressures to assess the role of the linear plug side truncation on the base pressure behavior. Numerical tests are carried out at supersonic flight Mach number. Copyright © 2005 by M. Geron and R. Paciorri.F. Nasuti, F. Sabetta, E. Martelli
Arctic waters: port Sabetta development
No full textPort Sabetta, located in the Russian Arctic along the Northern Sea Route, epitomizes the intersection of geopolitical interests, economic imperatives, and environmental challenges in the Arctic region. The article provides a comprehensive analysis of Port Sabetta's development, focusing on its environmental impact, socio-economic implications, and comparative analysis with other Arctic and non-Arctic ports. The geopolitical context and economic significance of Port Sabetta are explored, highlighting its strategic importance in Russia's Arctic strategy and global energy dynamics. An environmental impact assessment reveals the ecological risks associated with port construction, maritime operations, and industrial activities, emphasizing the need for proactive mitigation measures and regulatory oversight. The socio-economic implications of Port Sabetta's development are examined, including its effects on local communities, regional economies, and indigenous livelihoods. Case studies and comparative analysis of Arctic and non-Arctic ports provide insights into best practices and lessons learned for sustainable port development. The sustainable development of Port Sabetta requires a holistic approach that balances economic growth with environmental protection, social equity, and geopolitical stability
Una certa idea dell'azione sociale. Leggere insieme Merton e Bourdieu
No full textThis article intends to juxtapose (in an unprecedented way) the Robert K. Merton sociological approach to that of Pierre Bourdieu, within a systematics framework, and with the aim of overcoming canonic oppositions. The analysis is not proposed as schematically comprehensive: a detailed reconsideration of each consonance between Merton and Bourdieu will not be provided, nor are all the inevitable differences which run between the two authors examined. The specific interest is restricted to the action theory: the attempt is to envisage a basic pattern (a certain idea), shared by Merton and Bourdieu, that can cut across the established positions, with a specific heuristic value (the hypothesis)
