Economic growth and equality of opportunity

In this paper we argue that a better understanding of the relationship between inequality and growth can be obtained by shifting the analisys from the space of final achievements to the space of opportunities. To this end, we introduce the Opportunity Growth Incidence Curve, that can be used to evaluate the income dynamics of specific groups of the population and to infer the role of growth in the evolution of inequality of opportunity over time. By employng a rank dependent social welfare function we provide a rigorous normative justification for the use of the OGIC: we obtain suitable dominance conditions and we show how they can be interpreted in terms of OGIC dominance. We also propose an index that can be used to measure the impact of growth in terms of ooopotunity redistribution. Finally, we provide two empirical illustrations, for Italy and for Brasil, which show the potentials of the tools we have introduced.INCOME INEQUALITY, INEQUALITY OF OPPORTUNITY, ECONOMIC GROWTH

Long-term prediction of adherence to continuous positive air pressure therapy for the treatment of moderate/severe obstructive sleep apnea syndrome

BACKGROUND: Continuous positive airway pressure (CPAP) therapy is a highly effective treatment for obstructive sleep apnea syndrome (OSAS). However, poor adherence is a limiting factor, and a significant proportion of patients are unable to tolerate CPAP. The aim of this study was to determine predictors of long-term non-compliance with CPAP. METHODS: CPAP treatment was prescribed to all consecutive patients with moderate or severe OSAS (AHI ≥15 events/h) (n = 295) who underwent a full-night CPAP titration study at home between February 1, 2002 and December 1, 2016. Adherence was defined as CPAP use for at least 4 h per night and five days per week. Subjects had periodical follow-up visits including clinical and biochemical evaluation and assessment of adherence to CPAP. RESULTS: Median follow-up observation was 74.8 (24.2/110.9) months. The percentage of OSAS patients adhering to CPAP was 41.4% (42.3% in males and 37.0% in females), and prevalence was significantly higher in severe OSAS than in moderate (51.8% vs. 22.1%; p < 0.001; respectively). At multivariate analysis, lower severity of OSAS (HR = 0.66; CI 95 0.46-0.94) p < 0.023), cigarette smoking (HR = 1.72; CI 95 1.13-2.61); p = 0.011), and previous cardiovascular events (HR = 1.95; CI 95 1.03-3.70; p = 0.04) were the only independent predictors of long-term non-adherence to CPAP after controlling for age, gender, and metabolic syndrome. CONCLUSIONS: In our cohort of patients with moderate/severe OSAS who were prescribed CPAP therapy, long-term compliance to treatment was present in less than half of the patients. Adherence was positively associated with OSAS severity and negatively associated with cigarette smoking and previous cardiovascular events at baseline

DInSAR techniques for studying the October 23, 2011, Van earthquake (Turkey), and its relationship with neighboring structures

In October 2011 a strong earthquake hit the Van province, Eastern Turkey. Few days later (November 9th) an aftershock occurred few km southward. Finally in November 1976 another mainshock took place north of Van along the Caldiran fault. We have investigated the possible relations between 2011 mainshock and aftershock and the link with the 1976 earthquake. In order to complete the work SAR interferometry has been applied to measure surface displacements, while the fault geometries of the mainshock have been retrieved by a novel Neural Network approach. Moreover the CFF has been calculated to evaluate the role of 1976 earthquake in promoting the 2011 mainshock and, later on, the role of this latter respect to the aftershock in November 9th, 201

Looking for seismites in the Fucino basin: preliminary results from a combined geological geophysical approach.

We present a combined geological-geophysical study on the lacustrine sequence of the Fucino Plain (central Italy). New acquired data on liquefaction features and the recovery of a seismite in the lacustrine sequence are shown. Our preliminary results suggest the occurrence of three seismic events in the last ca. 45 kyr. Moreover, a first attempt to find out the source deposit responsible of the widespread liquefaction phenomena has been performed by means of shallow engine boreholes and ERT profiles

Younger medical specialists and longer waiting time:cohort study of the duration of medical training

OBJECTIVE: To describe trends and developments in the total duration of training medical specialists in the Netherlands, including their ages upon completion of the components of medical education: undergraduate medical program, waiting time and further post-graduate specialist training.DESIGN: Population cohort study.METHOD: From the combined data from Statistics Netherlands and the Registration Committee for Medical Specialists for the period 1986 to 2018 relevant populations were selected and training trajectories were mapped. The population size was 40,604 individuals for undergraduate medical programs, 41,885 for the duration of post-graduate specialist training, 31,915 for the waiting periods and 21666 for the total duration of the trajectory from the start of medical school until registration as a specialist.RESULTS: The median duration of undergraduate medical programs was 7.1 years, which is longer than the nominal duration and this remained unchanged over the observation period. The average waiting time between graduating medical school and postgraduate specialist training has increased from 2010 onwards to 3.7 years in 2018. The average duration of postgraduate specialist training is increasing. The average age at graduation of medical school fell by 1.7 years to 26.1. The average age at the start of post-graduate specialist training decreased, as did the average age at registration as a specialist.CONCLUSION: The total duration of training of medical specialists is stable. Changes such as "dedicated transition year" and flexible arrangements for postgraduate training have had no discernible influence on the total duration of medical training. Because the average age at start of postgraduate specialist training has decreased, medical specialists are on average younger upon registration.</p

‘Culture is a meritocracy’: Why creative workers’ attitudes may reinforce social inequality

The attitudes and values of cultural and creative workers are an important element of explaining current academic interest in inequality and culture. To date, quantitative approaches to this element of cultural and creative inequality have been overlooked, particularly in British research. This article investigates the attitudes of those working in creative jobs with a unique dataset: a web survey of creative workers’ attitudes (n = 2487). Using principal components analysis and regression, we have three main findings. First, in contrast to Richard Florida’s thesis on the attitudes and values of ‘the creative class’, our respondents’ attitudes were no more meritocratic than those of the general population. Second, those with the strongest belief in meritocracy in the sector are those in the most privileged positions, specifically those are best rewarded by the sector. Third, our research provides support for existing qualitative research on attitudes in the cultural sector, in which the worst rewarded workers are most aware of structural inequality. We conclude that the attitudes held by creative workers, and who holds which attitudes, make it unlikely that access to the sector and trajectories of individual progression within the sector will change. These findings also have important implications for current public interest in whether access to creative work is limited to those from privileged backgrounds

The March 11th, 2011, M 9.0 earthquake offshore Honshu island (Japan): a synthesis of the Tohoku-Oki INGV Team research activities

On March 11th, 2011 (at 05:46:23 UTC) a megaearthquake (M 9.0) occurred near the NE coast of Honshu island ( Japan), originated near the subduction plate boundary between the Pacific and the North America plates. The epicenter has been located at about 130 km East of Sendai city, at a depth of about 32 km. This seismic event has been followed by a devastating tsunami. The location, the geometric parameters, the focal mechanism, are in agreement with the occurrence of the earthquake along the subduction plate boundary. The initial seismological analysis indicated that a surface of about 300 km x 150 km over the fault moved upwards of 30-40 m. The Tohoku-Oki INGV Team has made available a wide and multisciplinary expertise to investigate the different scientific issues concerning the earthquake. Indeed from Seismology to Geomorphology, from Remote Sensing to GPS, from Tsunami to Source Modeling the INGV Team has completed a wide range of analysis, obtaining relevant outcomes that are summarized in this work.Published1-272T.
