Earnings Mobility in Italy, 1985-1996
No full textUsing a panel of administrative Italian data (source: INPS), this paper provides new empirical evidence on the earnings mobility in Italy over a relatively long time period (1985-1996). Transition matrices have been used to document the extent to which Italian employees change their position in the earnings ladder from one year to the next. Separate computations for the population as a whole and for various subgroups have helped to shed light on the underlying causes of the observed patterns.
Quando gli immigrati diventano operatori economici : il caso dell’edilizia rumena a Torino
No full textWage assimilation of immigrants and internal migrants : the role of linguistic distance
No full textPublished online: 01 Dec 2017The paper investigates the wage assimilation of foreign immigrants and internal migrants in Italy, comparing them with stayers. Control for selection in out-migration is performed using a new duration version of the Heckman correction and taking into account both return migration and moves to other destinations.
Internal migrants experience only minor wage differences when compared with stayers. By contrast, foreign immigrants earn about 8% less than stayers and internal migrants at the beginning of their careers, and the wage gap increases over time. Both language distance and job segmentation contribute to immigrants’ lack of wage assimilation
Short Employment Spells in Italy, Germany and the UK: Testing the Port of Entry Hypothesis
No full textThis paper looks at short employment spells in three European countries: Great Britain, whose labour market is considered the most flexible in the EU; Italy, regarded as the least flexible; and Germany, tightly regulated, but characterised by a deservedly famous apprenticeship system. In particular, it aims to assess whether young people in short-lived jobs stand a better chance of finding a 'good job' compared to their older colleagues. The increasingly held belief that - in modern economies - a 'bad job' at the beginning of one's career is the 'port-of-entry' to stable employment and to upward mobility, makes this assessment particularly relevant; ie it matters greatly if short-duration jobs are entry ports into better employment or become long term-traps. The lack of accepted benchmarks makes it difficult to reach strong conclusions in regard to the 'efficiency' of labour markets, however, this study should help to highlight the effect of different labour market institutions on mobility and on the soundness of the 'port-of-entry' hypothesis.

No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Counterfactual impact evaluation of hiring incentives and EPL reduction on youth employment in Italy
No full textThis study uses a counterfactual approach based on administrative registry data to evaluate the impact on youth employment of two selected demand-side public policies implemented in Italy in 2015: a rebate of social security costs (Law 190/2014, art. 1, c. 118) and a reduction in the costs to employers of firing employees (D. lgs n. 23/2015 under Law 183/2014).YEP - Youth Employment PartnerSHIPthis study uses a counterfactual approach based on administrative registry data to evaluate the impact on youth employment of two selected demand-side public policies implemented in italy in 2015: a rebate of social security costs (law 190/2014, art. 1, c. 118) and a reduction in the costs to employers of firing employees (d. lgs n. 23/2015 under law 183/2014). counterfactual impact evaluation of hiring incentives and epl reduction on youth employment in italy massimiliano deidda marco centra valentina gualtieri sergio scicchitano claudia villosio francesco trentin

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
