Women and Politics in Populist Times. A Case Study: the 2018 Electoral Campaign
No full textModern political cultures are rapidly reshaping themselves along with globalized social and economic change. In many countries the economic crisis seems to have also challenged political and institutional authority as well as their decisional capacity, creating a climate of uncertainty and distrust that seems to represent a threat for the democratic fiber of these nations.
Social and political scientists are registering a shift in the role of political parties, and new actors and “milieus” appear on the decision-making scene. A populist tide has arisen worldwide affecting political cultures and praxes as well as models of political leadership and keywords of the political debate.
If we look at the cross-national data, we find that populism does not necessarily exclude women from political leadership or participation. From Evita Peron’s call for women’s vote and activism back in 1947’s Argentina to Sarah Palin in the U.S. 2008 Republican’s presidential campaign to the Italian 5 Star Movements women mayor in two major cities such as Rome and Turin, populisms do not seem to disdain women in leading political position. What we do find is that, nonetheless, populism can and usually does entail a return to traits of macho culture, legitimating and re-proposing traditional feminine or even motherly roles for women. A cultural topos that is partially affecting even non- populist, progressive parties.
In this work we analyze how women in politics and women’s issues are being addressed in the political debate during the latest Italian Electoral Campaign (2018) when, in spite of the fact that more women have been candidate as members of parliament -and more women have won- compared to any previous Italian election, there has been a drawback in the targeting of feminist and feminine issues during the whole campaig
V-A and A-V modes in whole body and regional kinetics: domain of validity from a physiological model
No full textIn turnover studies, both at whole body and regional level, sources of tracer and tracee are in general nonidentical thus resulting in nonuniformity of specific activity (SA). Guidelines are available in literature to deal with the heterogeneous SA problem, and either the V-A or A-V modes, based on the arterial and mixed venous blood SA, respectively, have been recommended for different substrates. In particular, the A-V mode is considered the method of choice for studying lactate, amino acids, free fatty acid, etc. Guidelines are based on specific models chosen to describe kinetic and circulatory events of the substance under study but are often conflicting. A unitary physiological framework to understand assumptions of various models is also lacking. In this paper, we first review these models to assess their domain of validity. In particular, we point out major drawbacks that relate to the tissue compartment being treated as a lumped well-mixed pool with a single SA value. We then attempt to handle the nonuniform tissue SA by employing a more physiological model. The tissue system is thought to be made up of elementary units connected in parallel and categorized according to their functional ability to affect incoming SA. Potential changes of SA within individual units are examined. Thus each tissue unit may provide a different contribution to the overall change in SA, as measured in mixed venous blood. A spatial profile of SA is also identified both along the direction of blood flow and transversely toward the inner cellular space. This distributed model allows assessment of the domain of validity of V-A and A-V modes. We show that, in general, the V-A mode underestimates the production rate both at whole body and regional level, whereas the A-V mode can either under- or overestimate it
Intervista a Zygmunt Bauman:Vite in confessionale. Il Grande Fratello, l’11 settembre e la corsa libera dei poteri economici di fronte al crollo dello stato nazione
No full textAspetti geochimici dei sedimenti della Sacca di Goro (Delta del Po, Adriatico settentrionale)
No full textE’ stato affrontato uno studio sulle caratteristiche geochimiche dei sedimenti recenti della Sacca di Goro. Sono state eseguite analisi del contenuto di alcuni elementi maggiori (Al, Fe, Mn, Ti) ed in tracce (P, Li, Cr, Ni, Cu, Zn, Cd, Pb, Hg) insieme al contenuto di C organico, N totale ed olii minerali, su un totale di 131 campioni provenienti da 21 carote. I dati chimici sono stati elaborati congiuntamente ai dati tessiturali per via statistica, al fine di definire delle funzioni regionali di background naturale per la valutazione del grado di alterazione antropogenico dell’ambiente lagunare. I valori del fattore di arricchimento (EF) dei metalli considerati potenzialmente più pericolosi alla luce di una loro possibile interazione con la componente biologica all’interno della sacca, indicano valori massimi significativi > 5 per Hg, > 4 per Cd e Pb e > 2 per Zn e Cu. Gli arricchimenti si attestano nei livelli superficiali, per uno spessore massimo di circa 70-90 cm
Estimation of insulin sensitivity and glucose clearance from minimal model: new insights from labelled IVGTT.
No full textThe "minimal model" of glucose disappearance provides noninvasive estimates of insulin sensitivity and glucose effectiveness from an intravenous glucose tolerance test (IVGTT). However, this model does not allow the separation of glucose production from utilization. To overcome this limitation, labeled glucose was injected along with cold glucose in six normal dogs, and both cold and labeled glucose time courses were monitored along with insulin concentration. A revised minimal model was fitted to tracer data to obtain new measures of insulin sensitivity (SI* = 6.41 +/- 0.91 10(-4) min-1 X microU-1 X ml-1) and fractional glucose clearance (SG* = 0.0092 +/- 0.0009 min-1). SG* was compared with a direct measure obtained by a hepatic arterial-venous difference technique, which yielded a value of 0.0097 +/- 0.0002, virtually identical to SG*, thereby validating the model estimate. When the original minimal model was identified from cold data, we obtained S1 = 4.52 +/- 1.39 and SG = 0.042 +/- 0.009. SI* and SG* were different from SI and SG, respectively. In particular SG overestimates fractional glucose clearance by approximately five times. The revised minimal model yields glucose disposal parameters SI* and SG* that are not affected by the confounding effect of insulin and glucose inhibition of glucose production. Limitations inherent in cold IVGTT and original minimal model are overcome by labeled IVGTT and the revised minimal model, while test simplicity remains
Potenzialità e limiti della digestione anaerobica delle biomasse derivanti dalle fioriture macroalgali nella Sacca di Goro
No full textLe fioriture di specie macroalgali dei generi Ulva e Gracilaria rappresentano una seria minaccia per l’integrità ambientale e per lo sviluppo dell’allevamento della vongola verace nella Sacca di Goro (Delta del Po). Fino ad oggi la crescita delle macroalghe è stata in parte controllata mediante la raccolta delle biomasse prodotte che sono state smaltite prevalentemente in discarica. In questa nota è valutata la possibilità di impiegare le biomasse per produrre biogas. L’analisi dei dati disponibili per la Sacca di Goro ha dimostrato che le biomasse algali sono disponibili solo stagionalmente con quantitativi mediamente variabili tra 3000 e 6000 t di biomassa fresca. Il materiale algale presenta caratteristiche chimiche e biochimiche che ne dimostrano l’idoneità per l’uso proposto, con un limite, già rilevato nella letteratura internazionale, dovuto all’alto contenuto di ceneri e
di zolfo. In considerazione della disponibilità temporale e della qualità, le biomasse derivanti dalle fioriture macroalgali nella Sacca di Goro
possono essere impiegate in co-generazione, miscelate con altri materiali disponibili in loco: sottoprodotti agricoli e della pesca, materiale
vegetale da sfalcio, deiezioni animali (es. pollina). Su questi aspetti sono in corso prove pilota per verificare la resa in metano di diverse miscele
