Letture operaiste di Gramsci. Il caso Negri

2020

This article aims to analyze the relationship between Antonio Negri and the political and philosophical categories of Antonio Gramsci. It is my intention to resume, from the Sixties of the last century to nowadays, the stragegical uses of Gramsci’s thought by Negri. According to me, we can divide four periods in the theoretical framework of Negri. In the first one, Gramsci is an author incompatible with the workerist strategy of class struggle. In the second one, there is a sort of use of Gramsci against Gramsci. Pointendly, Negri tries to subtract the author of the Prison Notebooks from the prerogatives of the Pci. After the arrest of Negri in the 1979, Gramsci’s figure became more ambiguo…

Dall'operaismo a Marx

2022

The volume is the result of an annual work of the Self-managed Power Library and Sapere di Palermo. It is a double “monographic” work that attempts to return to a painting I model some reflections on Italian workerism, on its impact on the social articulation, e finally on some themes deriving from the new critical edition of the works of Marx and Engels

Simulazioni e dissimulazioni nella costruzione dello scenario: gli esami online durante la pandemia

2020

Due to the pandemic, in the University of Palermo (Italy) the remote mode was used for both teaching and final exams. Specifically, our reflection aimed at understanding the impact of the online exams on the “private dimension” of the students. According to the regulations of the University of Palermo, during the exams, the students must be visible in their own space, while the teachers were allowed to insert different screens to protect their private space. The result was, for the students, the public sharing of their spaces, the collective insertion into their private dimension and the manifestation of individual differences and inequalities in access to resources. Smart working involved …

AN OVERVIEW ON THE SUBTERRANEAN FAUNA FROM CENTRAL ASIA

2019

Survey of the aquatic subterranean fauna from caves, springs, interstitial habitat, wells in deserts, artificial tunnels (Khanas) of five countries of the former URSS (Kazakhstan, Kyrgyzstan, Tadjikistan, Turkmenistan, Uzbekistan) located far east the Caspian Sea. The cave fauna present some originalities: - the rich fauna of foraminiferida in the wells of the Kara-Kum desert (Turkmenistan); - the cave fish Paracobitis starostini from the Provull gypsum Cave (Turkmenistan); - the presence of a rich stygobitic fauna in the wells of the Kyzyl-Kum desert (Uzbekistan); - the rich stygobitic fauna  from  the hyporheic of streams and  wells around the tectonic Issyk-Kul Lake (Kyrgyzstan); - the e…

Segnalazioni floristiche e vegetazionali per le zone umide costiere del territorio di Petrosino (Sicilia occidentale)

2017

Si riportano popolazioni inedite di alcune specie di angiosperme rare per il territorio siciliano, localizzate nelle aree umide costiere del territorio di Petrosino (provincia di Trapani), attualmente tutelate come sito della rete europea “Natura 2000” (codice ITA010006), e come zona “Ramsar”: si tratta nel dettaglio di Apium graveolens, Briza minor, Carex extensa, Cladium mariscus, Euphorbia hirsuta, Ipomoea sagittata, Ruppia drepanensis, Sonchus maritimus. Per ogni specie viene brevemente illustrata l’importanza dei nuovi reperti nel contesto regionale. Viene inoltre segnalata la presenza di un habitat prioritario non censito nel piano di gestione del sito Natura 2000, ossia “7210*: Palud…

Presence and Absence in Global Virtual Team Meetings : Physical, Virtual, and Social Dimensions

2016

Global virtual work is commonly organised around virtual meetings. As virtual team members often belong to multiple groups in their work, finding time for global team meetings may be challenging due to competing priorities and roles as well as different time zones and schedules. Furthermore, social presence does not automatically emerge based on physical or virtual presence. Therefore, the notions of being physically, virtually and socially present or absent in global team meetings are important, and affect the collaboration of global work groups. These different dimensions of presence and absence and their nature as fluctuating phenomena have not yet been scrutinised in virtual work litera…

Arbitrary Phase Access for Stable Fiber Interferometers

2021

Well-controlled yet practical systems that give access to interference effects are critical for established and new functionalities in ultrafast signal processing, quantum photonics, optical coherence characterization, etc. Optical fiber systems constitute a central platform for such technologies. However, harnessing optical interference in a versatile and stable manner remains technologically costly and challenging. Here, degrees of freedom native to optical fibers, i.e., polarization and frequency, are used to demonstrate an easily deployable technique for the retrieval and stabilization of the relative phase in fiber interferometric systems. The scheme gives access (without intricate dev…

Phase error analysis of clipped waveforms in surface topography measurement using projected fringes

2021

Abstract When working with the method of projected fringes outside the optical laboratory one often encounters the problem of uncontrollable ambient light. This might cause saturation of the camera which in turn results in clipping of the fringes. Since standard theories describing phase-shifting techniques assume the projected fringes to be purely sinusoidal, such clipping will result in measurement error. In this paper a detailed analysis of this problem is given, and relations between phase errors, the amount of fringe clipping and the number of phase steps are found. Moreover, the phase difference between the clipped and the unclipped fringes is described. This investigation is based on…

El afrontamiento de los síntomas de burnout a través del significado de la tarea en profesionales que trabajan con personas con discapacidad intelect…

2021

This study examined an intervention that links task significance (one’s job has a positive impact on other people) to burnout symptoms of professionals working in organizations for individuals with intellectual disability. Professionals assigned to the experimental condition participated in teams designed to enhance the positive impact of their work on others (task significance). To do so, teams focused on a task to improve the quality of life of individuals with intellectual disability. Professionals assigned to the control condition did not participate in these teams, and they continued with their usual work. All the participating professionals answered a questionnaire about burnout…
