The effect of immigration along the distribution of wages

This paper analyses the effect immigration has on wages of native workers. Unlike most previous work, we estimate wage effects along the distribution of wages. We derive a flexible empirical strategy that does not rely on pre-allocating immigrants to particular skill groups. In our empirical analysis, we demonstrate that immigrants downgrade considerably upon arrival. As for the effects on native wages, we find that immigration depresses wages below the 20th percentile of the wage distribution, but leads to slight wage increases in the upper part of the wage distribution. The overall wage effect of immigration is slightly positive. The positive wage effects we find are, although modest, too large to be explained by an immigration surplus. We suggest alternative explanations, based on the idea that immigrants are paid less than the value of what they contribute to production, generating therefore a surplus, and we assess the magnitude of these effects

Cittadini senza diritti: abitare e lavorare a Milano da clandestini

Lo scopo di questo rapporto è di presentare le principali caratteristiche socio-demografiche dell’utenza Naga (Associazione Volontaria di Assistenza SocioSanitaria e per i Diritti di Stranieri e Nomadi Onlus), che costituisce una delle più grandi banche dati sull’immigrazione irregolare. A tal fine analizzeremo i dati contenuti nelle cartelle mediche del Naga per i pazienti che sono stati registrati tra il gennaio 2000 e il dicembre 2006, soffermandoci sulla loro nazionalità, genere, situazione familiare, anzianità migratoria, livello di istruzione, condizione lavorativa e situazione abitativa. Dall’analisi emerge un quadro delle caratteristiche e delle condizioni dei migranti privi di permesso di soggiorno del tutto diverso da quello spesso proposto nel dibattito politico e mediatico italiano. Gli immigrati irregolari sono giovani giunti di recente in Italia, ma hanno livelli di istruzione e tassi di occupazione che eguagliano – se non addirittura superano – quelli della popolazione residente in Italia. Le loro condizioni socioabitative, invece, sono assolutamente critiche e lontanissime dagli standard italiani

Tracking and Academic Prospects

This paper investigates the impact of secondary school tracking on students’ transitions to higher education (HE) in Italy. Using data from INVALSI and PISA surveys, we explore how track allocation – whether students attend academic, technical, or vocational schools – affects their academic outcomes and aspirations for higher education. There are significant disparities in transition rates between tracks, with students from vocational schools facing lower prospects of accessing higher education compared to their peers in academic tracks. These students not only demonstrate weaker skill growth over time but also lower aspirations for college, exacerbated by selective university admission policies based on standardized testing. The findings suggest that tracking reinforces social inequalities, with vocational students experiencing lower probabilities of entering tertiary education, especially under selective university admission policies. Revising vocational curricula, postponing track selection, or adjusting admission processes are policy measures that could improve equity in higher education access. Targeted interventions to support students in vocational tracks might also be needed to mitigate the long-term consequences of early academic tracking

A one-dimensional lattice model for a quantum mechanical free particle

Two types of particles, A and B with their corresponding antiparticles, are defined in a one dimensional cyclic lattice with an odd number of sites. In each step of time evolution, each particle acts as a source for the polarization field of the other type of particle with nonlocal action but with an effect decreasing with the distance: A -->...\bar{B} B \bar{B} B \bar{B} ... ; B --> A \bar{A} A \bar{A} A ... . It is shown that the combined distribution of these particles obeys the time evolution of a free particle as given by quantum mechanics.Comment: 8 pages. Revte

Evaluating the Labour Market Integration of New Immigrants in the UK

This article analyses the labour market integration of newly arrived immigrants in the UK labour market, based on data from the UK Labour Force Survey. We focus on immigrants who arrived in the United Kingdom since 2000 and distinguish different cohorts based on the year of their arrival in the country. We examine the extent to which these new arrivals were able to enter work and move up into skilled jobs, and analyse the sectors of the economy that have proved most amenable to this progression. The analysis indicates that these new arrivals fared relatively well in the workforce. In part as a result of their relative youth and high education levels, many new arrivals (especially those from the European Union and in particular the EU10 countries) moved straight into work

Multiple sulfatase deficiency with neonatal manifestation.

Multiple Sulfatase Deficiency (MSD; OMIM 272200) is a rare autosomal recessive inborn error of metabolism caused by mutations in the sulfatase modifying factor 1 gene, encoding the formylglycine-generating enzyme (FGE), and resulting in tissue accumulation of sulfatides, sulphated glycosaminoglycans, sphingolipids and steroid sulfates. Less than 50 cases have been published so far. We report a new case of MSD presenting in the newborn period with hypotonia, apnoea, cyanosis and rolling eyes, hepato-splenomegaly and deafness. This patient was compound heterozygous for two so far undescribed SUMF1 mutations (c.191C > A; p.S64X and c.818A > G; p.D273G)

Concussed patients with visually induced dizziness exhibit increased ocular torsion and vertical vergence during optokinetic gaze-stabilization

Visually Induced Dizziness (VID) is a common post-concussion sequalae that remains poorly understood and difficult to quantify. The present study aims to identify biomarkers for VID in the form of gaze-stabilizing eye movements. Nine patients with post-commotio VID and nine age-matched healthy controls were recruited by physiotherapists at a local neurorehabilitation centre. Torsional and vergence eye movements were recorded while participants viewed a series of optokinetic rotations where the central- and peripheral regions moved coherently, incoherently, or semi-randomly. Results showed that vergence and torsional velocities were increased in VID patients, reflecting increased oculomotor gain to visual motion, and that responses correlated with symptom severity. Coherent stimulation produced fastest torsional slow-phases across all participants; when faced with confliction directional information, eye movements tended to follow the direction of the central visual field, albeit at slower velocities than during coherent motion, meaning that while torsion was sensitive to visual content of the entire visual field it expressed directional preference to the central stimulation. In conclusion, post-commotio VID was associated with faster slow-phases during optokinetic gaze-stabilization, with both vergence and torsion being correlated to symptom intensity. As torsional tracking remains inaccessible using commercial eye-trackers, vertical vergence may prove particularly accessible for clinical utility

Recommendations for the quantitative analysis of landslide risk

This paper presents recommended methodologies for the quantitative analysis of landslide hazard, vulnerability and risk at different spatial scales (site-specific, local, regional and national), as well as for the verification and validation of the results. The methodologies described focus on the evaluation of the probabilities of occurrence of different landslide types with certain characteristics. Methods used to determine the spatial distribution of landslide intensity, the characterisation of the elements at risk, the assessment of the potential degree of damage and the quantification of the vulnerability of the elements at risk, and those used to perform the quantitative risk analysis are also described. The paper is intended for use by scientists and practising engineers, geologists and other landslide experts.JRC.H.5-Land Resources Managemen
