Non-standard work, low-paid work and employment dynamics : evidence from an occupational perspective
No full textIl lavoro parasubordinato in Italia: tra autonomia del lavoratore e precarietà del lavoro
No full textNell’ultimo decennio vi è stata una vasta diffusione di forme atipiche di lavoro. In questo contesto, nel nostro paese hanno visto larga diffusione i contratti di collaborazione coordinata e continuativa. Essi presentano tutti i requisiti per affiancare un più tradizionale rapporto a tempo indeterminato nelle sue fasi di transizione. Tuttavia, se, invece di affiancare i contratti tipici nelle fasi di transizione, i contratti di collaborazione si sostituissero stabilmente ad essi, allora potrebbe venirsi a creare un segmento di occupati a rischio di esclusione sociale. Le domande a cui è oggi di fondamentale importanza dare una risposta riguardano quindi l’evoluzione della carriera di questi individui.
Primo obiettivo di questo studio è quello di identificare, all’interno del mondo dei collaboratori, chi sono i soggetti a rischio, per poi coglierne l’evoluzione della carriera. A tale scopo si utilizza una banca dati unica nel suo genere: un campione dell’archivio INPS dei parasubordinati, individuale e longitudinale, che può essere legato ad altri archivi INPS (in particolare a quello dei dipendenti) e che copre il periodo più lungo al momento disponibile, ovvero dall’istituzione della gestione separata al 1999. La nostra analisi longitudinale fa emergere che l’attuale stock di parasubordinati è entrato nella gestione separata molto gradualmente nel tempo. La probabilità che nel breve periodo questi lavoratori passino ad un contratto di lavoro dipendente è più elevata per i soggetti giovani e che ricevono compensi modesti, e per i lavoratori che si muovono sul territorio; la probabilità di effettuare il passaggio inverso rimane più elevata per i soggetti che ricevono redditi minori, e mostra un andamento a campana in relazione all’età. In generale, infine, la parasubordinazione appare, soprattutto per le donne, una alternativa al lavoro part – time
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Protracted withdrawal from alcohol impacts excitability and dynamical properties of neurons of the bed nucleus of stria terminalis
No full textThe juxta-capsular subdivision of bed nucleus of stria terminalis (jcBNST) is part of the extended amygdala and plays an important role in the regulation of stress and reward related behaviors. This compact nucleus contains at least 3 types of biophysically diverse populations of GABAergic neurons that play an important role in the regulation of downstream neural circuits of the central amygdala. While drug-related neuroadaptive changes in the synaptic properties of BNST and other extended amygdala neurons have been well documented, their integrative properties and circuit interactions are also to be studied in order to gain a better understanding of the neurophysiological aspects of addictive behavior. Here we performed a series of dynamic clamp experiments with synthetic presynaptic voltage waveforms that were transformed to simulated excitatory and inhibitory synaptic conductances and injected into jcBNST neurons. This methodological approach allowed us to characterize how the temporal structure of the firing responses and the precision of spike timing depended on the type of neuron and how these properties were modified after prolonged withdrawal in alcohol dependent animals. Additionally, we performed a comprehensive analysis of neuronal responses under standard current clamp stimulation and used up to 12 characteristics of the neurons voltage output to compare their physiological properties, including resting membrane potential, membrane resistance, rehobase, the occurrence and intensity of post inhibitory response spikes, among others. In order to compare this complex set of physiological and dynamical parameters of jcBNST neurons from rats with a history of prolonged withdrawal and controls, we used the fuzzy K-means clustering algorithm, an unsupervised learning technique derived from a standard K-means algorithm. The goal of cluster analysis is the classification of objects based on similar properties among them and the subdivision into groups or clusters. Among the advantages of the fuzzy clustering algorithm one is that it allows objects to belong to several clusters simultaneously, with different degrees of membership. Our results showed that jcBNST neurons from normal animals displayed a higher degree of physiological diversity than those from dependent animals, meaning that the former subdivided into a greater number of clusters than the latter. Our experiments also showed that long-term neuroadaptive changes induced by drugs of abuse can alter populations of extended amygdala neurons in a way that might remain undetected if evaluating only their gross physiological properties
Una misura monetaria della precarietà dei lavoratori italiani
No full textFlexibility - which in many European countries has been introduced or enhanced through the liberalization of non-standard contracts - does not necessarily imply work insecurity. By looking at a monetary measure of what one gets from the labor market and the social protection system in the medium run, we offer a new assessment of job precariousness in Italy. In particular, we find that: i) many non-standard workers are not insecure; ii) work insecurity also involves a non-negligible share of standard workers; iii) this notwithstanding, the risk of work insecurity for non-standard workers is significantly larger than for standard ones
