Industrialization and Intergenerational Mobility in Sweden

The relationship between industrialization and intergenerational mobility has been a topic of discussion for over forty years. In this article both total mobility and relative mobility chances are studied in the decades preceding industrialization and the decades during industrialization. A high-quality data set is used covering the male population of a region in the north of Sweden during the 19th century. Total intergenerational mobility increased during industrialization until, at the end of the century, both industrialization and the growth of mobility stagnated. Sectorial barriers resulted in unequal relative mobility chances before and also during industrialization. However, sons from self-employed classes were less likely to inherit the class position of their father after the onset of industrialization. At the same time, mobility between classes differing in status became less frequent. These results show a decline in the importance of the direct transfer of resources between generations and may indicate the increasing importance of education

Social Mobility through Migration to the Colonies: The Case of Algeria

Most migrants move to further their economic and social position. How successful were they, and which migrants succeeded best? Would they have fared better if they had stayed at home? These questions are often raised regarding recent migrants to the United States and Europe, who often entered the labor market in relatively low positions. During their lifetime, many migrants improve their social position, as do subsequent generations. The migrants to Algeria during French colonial rule, however, entered the labor market at the higher echelons of society. Did they fare better than their parents? If so, did their descendants keep their relatively privileged colonial position? The effects of gaining or losing social, cultural, economic, and human capital appear to be different for various groups of migrants who moved to colonies, tweaking existing theories in economic history, settler history, and the sociology of migration

Intergenerational Transfer of Occupational Status in Portugal, 1850-1960: Unravelling Modernization Processes

This paper sets out to investigate the consequences of modernization processes as they took place in Portugal between 1850 and 1960 on the transfer of occupational status from father to son. Information from marriage registers in six municipalities in Portugal will be used

Investigating strangeness enhancement with multiplicity in pp collisions using angular correlations

A study of strange hadron production associated with hard scattering processes and with the underlying event is conducted to investigate the origin of the enhanced production of strange hadrons in small collision systems characterised by large charged-particle multiplicities. For this purpose, the production of the single-strange meson KS0 and the double-strange baryon Ξ± is measured, in each event, in the azimuthal direction of the highest-pT particle (“trigger” particle), related to hard scattering processes, and in the direction transverse to it in azimuth, associated with the underlying event, in pp collisions at s = 5.02 TeV and s = 13 TeV using the ALICE detector at the LHC. The per-trigger yields of KS0 and Ξ± are dominated by the transverse-to-leading production (i.e., in the direction transverse to the trigger particle), whose contribution relative to the toward-leading production is observed to increase with the event charged-particle multiplicity. The transverse-to-leading and the toward-leading Ξ±/KS0 yield ratios increase with the multiplicity of charged particles, suggesting that strangeness enhancement with multiplicity is associated with both hard scattering processes and the underlying event. The relative production of Ξ± with respect to KS0 is higher in transverse-to-leading processes over the whole multiplicity interval covered by the measurement. The KS0 and Ξ± per-trigger yields and yield ratios are compared with predictions of three different phenomenological models, namely Pythia8.2 with the Monash tune, Pythia8.2 with ropes and EPOS LHC. The comparison shows that none of them can quantitatively describe either the transverse-to-leading or the toward-leading yields of KS0 and Ξ±.publishedVersio

Multiplicity dependence of charged-particle intra-jet properties in pp collisions at √s = 13 TeV

The first measurement of the multiplicity dependence of intra-jet properties of leading charged-particle jets in proton–proton (pp) collisions is reported. Themean chargedparticle multiplicity and jet fragmentation distributions are measured in minimum-bias and high-multiplicity pp collisions at center-of-mass energy √s = 13 TeV using the ALICE detector. Jets are reconstructed from charged particles produced in the midrapidity region (|η| < 0.9) using the sequential recombination anti-kT algorithm with jet resolution parameters R = 0.2, 0.3, and 0.4 for the transverse momentum (pT) interval 5–110 GeV/c. The highmultiplicity events are selected by the forward V0 scintillator detectors. The mean charged-particle multiplicity inside the leading jet cone rises monotonically with increasing jet pT in qualitative agreement with previous measurements at lower energies. The distributions of jet fragmentation function variables zch and ξ ch are measured for different jet-pT intervals. Jet-pT independent fragmentation of leading jets is observed for wider jets except at high- and low-zch values. The observed “hump-backed plateau” structure in the ξ ch distribution indicates suppression of low-pT particles. In high-multiplicity events, an enhancement of the fragmentation probability of low-zch particles accompanied by a suppression of high-zch particles is observed compared to minimum-bias events. This behavior becomes more prominent for low-pT jets with larger jet radius. The results are compared with predictions of QCD-inspired event generators, PYTHIA8 with Monash 2013 tune and EPOS LHC. It is found that PYTHIA8 qualitatively reproduces the jet modification in high-multiplicity events except at high jet pT. These measurements provide important constraints to models of jet fragmentation.publishedVersio

Search for jet quenching effects in high-multiplicity pp collisions at √ s = 13 TeV via di-jet acoplanarity

The ALICE Collaboration reports a search for jet quenching effects in highmultiplicity (HM) proton-proton collisions at √ s = 13TeV, using the semi-inclusive azimuthaldifference distribution Δφ of charged-particle jets recoiling from a high transverse momentum (high-pT,trig) trigger hadron. Jet quenching may broaden the Δφ distribution measured in HM events compared to that in minimum bias (MB) events. The measurement employs a pT,trig-differential observable for data-driven suppression of the contribution of multiple partonic interactions, which is the dominant background. While azimuthal broadening is indeed observed in HM compared to MB events, similar broadening for HM events is observed for simulations based on the PYTHIA 8 Monte Carlo generator, which does not incorporate jet quenching. Detailed analysis of these data and simulations show that the azimuthal broadening is due to bias of the HM selection towards events with multiple jets in the final state. The identification of this bias has implications for all jet quenching searches where selection is made on the event activity.publishedVersio

Intergenerational mobility from a historical perspective

This chapter synthesises the international evidence on the impact of secondary and higher education expansion on intergenerational inequality in education. In high-income countries, the association between social origin (parental education, parental income, social class background) and educational outcomes (highest level of educational attainment, tertiary education) generally persisted then declined as national education systems expanded during the twentieth century, in line with the predictions of modernisation theorists. Nevertheless, levels of intergenerational inequality in education remained substantial into the twenty-first century, particularly in relation to parental education, suggesting the relatively greater importance of cultural over economic capital. Moreover, earlier trends towards equalisation appear to have ceased into the twenty-first century, with indications of a possible ‘U-turn’ ahead with respect to comparative rates of access to higher education. In lower-income countries, intergenerational inequalities in education are larger, have been slower to diminish, and are more strongly linked to economic inequality
