Córtazar in the middle of Pulp culture and political denunciation
2018
In Fantomas against the multinational vampires (1975) Julio Cortázar mixes a verbal narration with comic strips and with the Russell Tribunal political report. The text is a place of negotiation between some different ways of understanding the relationship between literature, culture and politics. Cortazar was trying to give an answer to the latinoamerican intellectual debates on these issues.
Correlates of the non-use of contraception among female university students in Italy
2021
The present paper scrutinizes the correlates of the non-use of contraception among young women in Italy. To this end we consulted two releases of Selfy (Sexual and Emotional LiFe of Youths) survey, which offer information for a nationally sample of university students. The results reveal that the likelihood of non-using contraception is higher among women living in the South and among those with previous experience of unsafe sexual behaviours. The risk of unprotected sex is also higher within a group of students who are relatively older than the others and live in a stable cohabiting union.
Postmodernity, insecurity and job loss Focus on the unemployed's suffering
2017
International audience; Objectives Recent research shows clear correlations between the subjective perception of job's insecurity and physical, mental and relational health. This article highlights the difficulties of workers , and particularly the impact of uncertainty and job loss on their self-esteem and psycho-physical well-being. The work presents and contextualizes the perception of job insecurity as an effect of postmodern society.Methods The research involved 60 subjects that have lost the jobs and received a 3 month intervention of active policies organized in groups focusing on empowerment and employability. At two times before and after group participants filled in Rosenberg Self…
Unraveling the three faces of self-esteem: A new information-processing sociometer perspective
2009
Abstract Based on an integration of sociometer theory and information-processing models, the present study investigated the predictive validity of three self-esteem measures: self-report, an implicit association test, and an affective priming task. In a first session, self-esteem measures were obtained from 93 participants. After an interval of four weeks, interpersonal perception ratings were collected in small round-robin groups. Participants were requested to briefly introduce themselves to the group before evaluating one another and indicating how they expected to be evaluated by the others (metaperceptions). As hypothesized, all three self-esteem measures independently predicted the pe…
Forecasting correlated time series with exponential smoothing models
2011
Abstract This paper presents the Bayesian analysis of a general multivariate exponential smoothing model that allows us to forecast time series jointly, subject to correlated random disturbances. The general multivariate model, which can be formulated as a seemingly unrelated regression model, includes the previously studied homogeneous multivariate Holt-Winters’ model as a special case when all of the univariate series share a common structure. MCMC simulation techniques are required in order to approach the non-analytically tractable posterior distribution of the model parameters. The predictive distribution is then estimated using Monte Carlo integration. A Bayesian model selection crite…
Automated detection of protein unfolding events in atomic force microscopy force curves
2016
Atomic force microscopy is not only a high-resolution imaging device but also a mechanical machine, which can be used either to indent or stretch (soft) biomaterials. Due to the statistical nature of such materials (i.e., hydrogels or polymers) hundreds of force-distance curves are required to describe their mechanical properties. In this manuscript, we present an automated system for polymer unfolding detection based on continuous wavelet analysis. We have tested the automated program on elastin, which is an important protein that provides elasticity to tissues and organs. Our results show that elastin changes its mechanical behavior in the presence of electrolytes. In particular, we show …
Monte Carlo simulation of many-arm star polymers in two-dimensional good solvents in the bulk and at a surface
1991
A Monte Carlo technique is proposed for the simulation of statistical properties of many-arm star polymers on lattices. In this vectorizing algorithm, the length of each arml is increased by one, step by step, from a starting configuration withl=1 orl=2 which is generated directly. This procedure is carried out for a large sample (e.g., 100,000 configurations). As an application, we have studied self-avoiding stars on the square lattice with arm lengths up tol max=125 and up tof=20 arms, both in the bulk and in the geometry where the center of the star is adsorbed on a repulsive surface. The total number of configurations, which behaves asN∼l γ G–1μ fl , whereμ=2.6386 is the usual effective…
Development of core-shell colloids to study self-diffusion in highly concentrated dispersions
2007
To study single particle motion in highly concentrated colloidal dispersions, a host-tracer colloid system was developed, consisting of crosslinked polymer micronetwork spheres placed in a good solvent. The host colloid is made invisible to the experimental probe by matching its refractive index to that of the solvent. For the tracer particles a core-shell structure was chosen to ensure the interaction potential to be identical to that of the host particles. Therefore the shell was made of the same polymer as the host. The core differs in refractive index from the solvent and is therefore visible due to scattered light.
