Hybridisation of work and the platform informal revolution
Full text linkFocusing on the gig-economy, this contribution looks at platforms as the key vectors of a process of informalisation of the economy and of hybridisation of working arrangements. In the capitalism of infrastructures informality has far from disappeared from the scene of contemporary, rather, it is increasingly becoming an integral factor of the «home-delivered world» society, through an increasing «informalisation» of formal labour and a refeudalisation of working conditions. From this perspective, on-demand platforms stand at the forefront of this process of informalisation. On one hand, they expand the borders of capitalist financial accumulation extracting value from activities historically at the margins of the market economy. On the other, platforms are strongly intertwined with the political informalisation of labour relations as well as with the exploitation of masses of workers in both the global North and South. Based on a multi-sited ethnography between Italy and Argentina on the platform-based last-mile logistics, this contribution empirically highlights the interconnection between formal and informal circuits of labour in platform work, revealing a baroque economy in which informal, illicit, solidaristic, and predatory behaviours are intertwine
The camp form and the experience infrastructures: A counter-fatal research perspective
No full textCan a cross- sectional reading of the various historical forms in which a specific method – the camp form – of a specific collectivity has taken shape, and what (the people) is to be kept separate from it, be formulated? The difficulties that hinder attempts to present a single reading linking together different places and spaces – refugee camps, concentration camps, transit camps, identification camps – in which such practices take concrete shape (de facto, the building of a boundary), with widely varying purposes, meanings and consequences, should not be underestimated. Far from ignoring such distinctions, they must be used, increasing abstraction by a degree, in order to focus on the ways in which a social configuration functions (this is the underlying hypothesis), a ‘sociation form’ in Georg Simmel’s words. The objective, in other words, is to come up with a social organization logic that bypasses specific subjects’ experiences – however dramatic – of the (diverse) concrete manifestations of the camp form. According to this hypothesis, in fact, the forms of interaction – to use Simmel’s words once again – constitute the visible element in a more complex social logic: a social form is to be analysed as a ‘concept of reality [...] as a network of reciprocal influences between a plurality of elements’
Immagini del lavoro che emerge. Dati e riflessioni a partire da due indagini sul rapporto di collabora-zione coordinata e continuativa
No full textLe riflessioni contenute in questo paper derivano da due ricerche sul campo su lavoratori con contratto di collaborazione coordinata e continuativa in cui si è posto al centro dell'analisi il nesso fra condizioni lavorative e condizioni di vita in una prospettiva di genere. Fra i temi trattati: il rapporto fra questa condizione occupazionale e la maternità, l'interesse verso altre forme di lavoro, il rapporto fra autonomia ed eteronomia, la questione del riconoscimento, la centralità della risorsa formazione
Lavoro in movimento.Collaborazioni coordinate e continuative: riflessioni da una ricerca sul campo
No full textThis research on sub-contracting self-employed workers shows a greater risk of precariousness for women and for workers with lower levels of education, and higher uncertainty and asymmetry information for workers who are also characterised by a discontinuois work-profile with under-employment and over-employment spells (the latter often under need to achieve a sustainable income or owing to precautionary behaviour) and with training periods or need for training. The research also shows constraints in terms of new family formation, fertiliy, expenditure, social capital erosion as well as a significant tension towards permanent dependet work
Ultra-High Q-Factor Silicon Resonator for High Frequency Oscillators
Full text linkThe thesis focuses on the investigation and characterisation of ultra-high Q-factor low loss Silicon resonators with transverse electric (TE)-like electromagnetic band-gap determined by two dimensional periodic structure made of a Silicon slab having a triangular lattice of air cylinders. A band-gap is observed where no energy is propagated through the slab, however engineering defects are created and optimised within the lattice producing resonant cavities and waveguides. The structure being excited with the fundamental TE10 mode can be coupled to external circuits via waveguides and its respective transitions in co-planar waveguide transmission line used to convey the millimetre-wave frequency signals.
The ultimate goal is to investigate and characterise the promising low loss and high frequency Silicon resonators suitable for millimetre-wave communications such as used in low phase noise oscillator application and band pass filters.
The results clearly show that electromagnetic band-gap structures or photonic crystals (PC) can be utilized for application in high frequency oscillators directly in fundamental mode with great benefits in obtaining ultra-high Q-factor and therefore low phase noise; and with better performance than alternative state-of-art technologies such as crystal oscillators in combination with frequency multiplication or frequency synthesis causing an increase in the overall phase noise by 20 log rule.
By successfully demonstrating the experiment of using electromagnetic band-gap structures with oscillators, it is a great contribution towards the solution of the problem of high phase noise affecting high frequency oscillators operating at millimetre-wave band
Evolving geometries: Power, territory, and knowledge in the infrastructure of energy communities
No full textEnergy communities seem to hold great promise for addressing the challenges of a just energy transition. They are expected to shift energy production to local territories, bring new actors into energy governance and intervene to reshape existing power dynamics. However, these expectations often lead to placing the responsibility for change on communities, as if they were designed to mechanically transform energy systems. This ignores the fact that energy communities navigate through domains of uncertainty where techno-managerial approaches impede the possibilities for radical change. The article suggests that adopting an infrastructural perspective can enhance and innovate the discourse on energy communities in the social sciences. Arguing that both energy infrastructures and energy communities exist in a field of tension in which three crucial infrastructural dimensions – power, territory, and knowledge – create different relational geometries, this paper proposes a new categorisation for understanding energy communities through an infrastructural lens. The aim is to identify which specific geometries of power, territory and knowledge are best positioned to build energy communities capable of challenging the current energy infrastructure. The article states that energy communities are neither conservative nor inherently revolutionary, suggesting that the transformative capacity of energy communities depends on specific infrastructural assemblages
Differenze di genere nell'accesso a posizioni apicali. Risultati di una ricerca sul campo
No full textIl lavoro studia l'accesso delle donne alle posizioni apicali. L'analisi empirica è svolta sui dati ECHP (European Community Household Panel), specificando un modello econometrico di probabilità di accesso alle occupazioni dirigenziali, corretto per la selezione all'occupazione. L'analisi conferma l'esistenza di un diverso accesso di uomini e donne alle cariche dirigenziali. Per quanto concerne le caratteristiche produttive, lo studio evidenzia come le donne debbano investire molto in capitale umano per poter ridurre il divario di genere nell'accesso a ruoli manageriali. I risultati dell'analisi evidenziano la presenza di modelli di carriera diversi tra donne e uomini
