Disposable Workforce in Italy

This paper explores the “disposable” patterns of workforce utilization in Italy. The term “disposable” reflects the fact that people enter the labor market, their services are “used” as a disposable commodity for few years, after which they leave the labor market and are no longer observable in the official data. Out of 100 new young entries, only 70 are still in the labor market 10 years after entry if their first job spell was at least one year long. For those – three times as many - whose first job is short (youth employment, unemployment, unemployment duration.

Long term youth unemployment or disposable workforce?

This paper explores a process which I denote as “young workforce disposal” (YWD). YWD reflects the fact that many young people enter the labor market as dependent employees, at some later time they are dismissed and (presumably) move into never-ending unemployment. Long term unemployment may last two, three, four years, but, in the end, it should lead to re-entry in working activities. If it does not, i.e. if we observe young men separating from their jobs for whatever reason, and, for as long as ten or more years, disappearing from the labor force altogether, then it becomes problematic to define such events simply as long term unemployment. YWD seems to be an appropriate denomination, as it conveys the idea that young workers become a disposable commodity. Workforce disposal is evident and dramatic in Italy: out of 100 new young entries, about 70 are still in the labor market 10 years after entry if their first job spell was at least one year long. For those – three times as many - who have started their career with a short employment spell (

Disposable Workforce in Italy

This paper explores the "disposable" patterns of workforce utilization in Italy, well under way before the cyclical downturn of the early 90's and before the main reforms of the Italian labor market. The term "disposable" reflects the fact that many young people enter the labor market, their services are "used" as a disposable commodity for a few years, after which they leave the labor market altogether and are no longer observable in the official (administrative) data. Workforce disposal is evident and dramatic: out of 100 new young entries, about 70 are still in the labor market 10 years after entry if their first job spell was at least one year long. For those – three times as many – who have started their career with a short employment spell (youth employment, unemployment, unemployment duration

Context factors and student achievement in the IEA studies: evidence from TIMSS

Abstract Background The present study investigates what factors related to the school context influence student achievement on TIMSS mathematics tests across countries. A systematic review of the literature on PIRLS, TIMSS, and ICCS was conducted upstream to identify those school, teacher, and classroom factors shown to be useful predictors of student performance in previous IEA studies. Data of student samples representative of grade 8 students from 28 countries who participated in TIMSS 2011 were analysed. The main aim of the present study is to verify what school and teacher characteristics are positively associated with students' mathematics achievement, mainly focusing on disadvantaged schools. Furthermore, it aims at identifying how school context variables contribute to explaining the performance of students in disadvantaged schools in comparison with more advantaged schools. Methods A separate analysis was carried out for each considered country, and the same multilevel regression model was used on the sampled schools as a whole and treating schools with high (highest tertile) and low (lowest tertile) socio-economic backgrounds as distinct groups. Results The results confirmed that a high socio-economic status has a significant and positive effect on student achievement: compared with students from socio-economic disadvantaged schools, students from advantaged schools performed better in mathematics achievement. This difference is more evident in countries where the gap between rich and poor people as measured by the Gini coefficient, which measures how much an economy deviates from perfect equality, is wider. However, this difference is restricted in countries with a smaller gap between rich and poor people. Conclusions According to the literature in the field, the results show significant differences across countries in relation to the school and teacher characteristics that have an impact on mathematics achievement of students from low and high SES schools. Different patterns were also found within countries for low and high SES schools

Fiscal Impact of EU Migrants in Austria, Germany, the Netherlands and the UK

This study was undertaken to estimate some aspects of the net fiscal impact of EU migrants in four EU countries Austria, Germany, the Netherlands and the United Kingdom. The report outlines the role of Fiscal Impact of EU Migrants in Selected Countries migrants from EU countries as participants in the labour market, as taxpayers and as benefit recipients also. The fiscal contribution of EU foreigners has increased substantially in the past several years. Compared to 2009, inn 2013 EU migrants paid 31% more in direct taxes as their wages increased and more EU workers found employment opportunities in Austria, Germany, the Netherlands, and the UK. As migration accelerated, EU foreigners also paid 44% more on indirect taxes, as they spent more onconsumer purchases. EU foreigners in Austria, Germany, the Netherlands and the UK received 35% more benefits than they did in 2009, due to the overall expansion of the welfare state in addition to the inflow of EU migrants

SALSA: A Novel Dataset for Multimodal Group Behavior Analysis

Studying free-standing conversational groups (FCGs) in unstructured social settings (e.g., cocktail party ) is gratifying due to the wealth of information available at the group (mining social networks) and individual (recognizing native behavioral and personality traits) levels. However, analyzing social scenes involving FCGs is also highly challenging due to the difficulty in extracting behavioral cues such as target locations, their speaking activity and head/body pose due to crowdedness and presence of extreme occlusions. To this end, we propose SALSA, a novel dataset facilitating multimodal and Synergetic sociAL Scene Analysis, and make two main contributions to research on automated social interaction analysis: (1) SALSA records social interactions among 18 participants in a natural, indoor environment for over 60 minutes, under the poster presentation and cocktail party contexts presenting difficulties in the form of low-resolution images, lighting variations, numerous occlusions, reverberations and interfering sound sources; (2) To alleviate these problems we facilitate multimodal analysis by recording the social interplay using four static surveillance cameras and sociometric badges worn by each participant, comprising the microphone, accelerometer, bluetooth and infrared sensors. In addition to raw data, we also provide annotations concerning individuals' personality as well as their position, head, body orientation and F-formation information over the entire event duration. Through extensive experiments with state-of-the-art approaches, we show (a) the limitations of current methods and (b) how the recorded multiple cues synergetically aid automatic analysis of social interactions.

Microvesicles: Novel Biomarkers for Neurological Disorders

Microvesicles (MVs) are released by most cell types in physiological conditions, but their number is often increased upon cellular activation or neoplastic transformation. This suggests that their detection may be helpful in pathological conditions to have information on activated cell types and, possibly, on the nature of the activation. This could be of paramount importance in districts and tissues that are not accessible to direct examination, such as the central nervous system. Increased release of MVs has been described to be associated to the acute or active phase of several neurological disorders. While the subcellular origin of MVs (exosome or ectosomes) is basically never addressed in these studies because of technical limitations, the cell of origin is always identified. Endothelium- or platelet-derived MVs, detected in plasma or serum, are linked to neurological pathologies with a vascular or ischemic pathogenic component, and may represent a very useful marker to support therapeutic choices in stroke. In neuroinflammatory disorders, such as multiple sclerosis, MVs of oligodendroglial, or microglial origin have been described in the cerebrospinal fluid and may carry, in perspective, additional information on the biological alterations in their cell of origin. Little specific evidence is available in neurodegenerative disorders and, specifically, MVs of neural origin have never been investigated in these pathologies. Few data have been reported for neuroinfection and brain trauma. In brain tumors, despite the limited number of studies performed, results are very promising and potentially close to clinical translation. We here review all currently available data on the detection of MVs in neurological diseases, limiting our search to exclusively human studies. Current literature and our own data indicate that MVs detection may represent a very promising strategy to gain pathogenic information, identify therapeutic targets, and select specific biomarkers for neurological disorders

Milk microbiome: evaluation study on the differences among cows with a different health status classified by leukocyte pattern

Milk is considered not only a source of nutrient for the offspring but also a font of immunoregulatory compounds capable to predispose the na\uefve intestinal immune system of the new-born to react to the external environment. In the present study we evaluated the composition of milk microbiome from cows classified according to milk total and differential somatic cell counts. A total of 34, 13 and 13 milk samples of healthy, at risk and subclinical or chronic cows, respectively, were collected during the same milking from a local dairy herd. Through Next Generation Sequencing (NGS) of bacterial 16S rRNA gene, the differences of taxa in terms of relative abundances (RA) and alpha and beta biodiversity were analysed. The RA of several genera were statistically significant in the three groups, such as Arcanobacterium (p=0.001), Rhodococccus (p<0.05) and Rubrobacter (p<0.05), while at species level the presence of Propionibacterium granulosum, Pseudomonas alcaligenes and Prosthecobacter debontii were found. Shannon and Evenness indices computed at the genus level were not significant, while beta biodiversity showed a clear clusterization between groups. The results highlighted that milk microbiome is associated to a different cellular response at udder level, although more specific studies are needed to assess the source of bacteria species identified in milk microbial population of healthy animals

Ordered-disordered domain coexistence in ternary lipid monolayers activates sphingomyelinase by clearing ceramide from the active phase

We explored the action of sphingomyelinase (SMase) on ternary monolayers containing phosphatidylcholine, sphingomyelin (SM) and dihydrocholesterol, which varied along a single tie line of phase coexistence. SMase activity exhibited a higher rate and extent of hydrolysis when the film is within the liquid-expanded (LE)/liquid-ordered (LO) coexistence range, compared to monolayers in the full LO phase. Since Alexa-SMase preferably adsorbs to the LE phase and there was no direct correlation found between enzymatic activity and domain borders, we postulate that the LE phase is the active phase for ceramide (Cer) generation. The enzymatically generated Cer was organized in different ways depending on the initial LE/LO ratio. The action of SMase in Chol-poor monolayers led to the formation of Cer-enriched domains, while in Chol-rich monolayers it resulted in the incorporation of Cer in the LO phase and the formation of new Chol- and Cer-enriched domains. The following novel mechanism is proposed to provide an explanation for the favored action of SMase on interfaces that exhibit an LE-LO phase coexistence: the LO phase sequesters the product Cer causing its depletion from the more enzyme-susceptible LE phase, thus decreasing inhibition by the reaction product. Furthermore, LO domains function as a substrate reservoir by allowing a rapid exchange of the substrate from this phase to the SM-depleted LE phase.Fil: Ale, Elisa Carmen.
