The Effect of Family Income during Childhood on Later-life Attainment: Evidence from Germany

We examine the impact of family income during childhood on the type of secondary school that German children attend, a good indicator of their lifetime socioeconomic attainment. By contrast with several US child outcome studies, we find that late-childhood income is a more important determinant of outcomes than early-childhood income, and income effects are not greater for poor households compared to rich households, other things equal. The income effects are small for native-born German children and non-existent for children from guestworker households. Income effects are also small relative to the impact of differences in parental educational qualifications or institutional factors related to the federal state of residence.child poverty, educational achievement, schooling, family background

The Dynamics of Child Poverty: Britain and Germany Compared

We compare patterns of movements into and out of poverty by children in Britain and Germany using data from the British Household Panel Survey and the German Socio- Economic Panel for the period 1992-7. Compared to Germany, in Britain poverty persistence is greater, and poverty exit rates in particular are lower. In both countries poverty is particularly persistent among children in lone parent households and households with a nonworking head. Events such as family formation and dissolution, and changes in household labour market attachment are associated with child poverty transitions in the direction expected, and in both countries. However a large fraction of the observed poverty transitions are not accounted for by these events.

On the role of galactic magnetic halo in the ultra high energy cosmic rays propagation

The study of propagation of Ultra High Energy Cosmic Rays (UHECR) is a key step in order to unveil the secret of their origin. Up to now it was considered only the influence of the galactic and the extragalactic magnetic fields. In this article we focus our analysis on the influence of the magnetic field of the galaxies standing between possible UHECR sources and us. Our main approach is to start from the well known galaxy distribution up to 120 Mpc. We use the most complete galaxy catalog: the LEDA catalog. Inside a sphere of 120 Mpc around us, we extract 60130 galaxies with known position. In our simulations we assign a Halo Dipole magnetic Field (HDF) to each galaxy. The code developed is able to retro-propagate a charged particle from the arrival points of UHECR data across our galaxies sample. We present simulations in case of Virgo cluster and show that there is a non negligible deviation in the case of protons of $7 \times 10^{19}$ eV, even if the $B$ value is conservative. Then special attention is devoted to the AGASA triplet where we find that NGC3998 and NGC3992 could be possible candidates as sources.Comment: Version accepted from ApJ, 5 figure

Interaction of Public and Private Employment: Evidence from a German Government Move

We use the move of the seat of the German government from Bonn to Berlin in 1999 to test competing views about the impact of public employment on private sector activity in a local labor market. A relocated public sector job might create new jobs in an area as it increases demand for locally-produced goods and services, or crowd out existing jobs due to upward pressure on housing rents. Using employment data from a panel of a 50% sample of establishments across 190 Berlin postcodes, we apply a treatment intensity approach which takes the possibility of spillovers into account. Results indicate that the arrival of 100 public sector jobs into an area generates 55 additional jobs in the private sector. There is evidence of spillovers: relocations up to a distance of 1km from a postcode boundary increases employment in the private sector by 36 jobs. These effects are coming through job gains in the service sector, while manufacturing employment is not influenced by the relocation

Is it time to talk? Interpreter services use in general practice within Canterbury

INTRODUCTION: Effective communication is fundamental to successful health care service delivery, and has a positive impact on access, quality of care, health outcomes, and patient satisfaction. Although there are a growing number of New Zealanders who do not speak English proficiently, underutilisation of trained interpreter services appears to be common in primary health care settings. AIMS: To describe the pattern of interpreter service need and utilisation by general practice services, and to identify key barriers and enabling factors to the use of trained interpreters. METHODS: A mixed methods study was employed. Census and Partnership Health Canterbury Te Kei o Te Waka (PHC) databases were combined, and quantitative analysis used to derive interpreter service need and utilisation patterns. Transcripts of focus groups and interviews from general practitioners, practice nurses and practice administration staff within the PHC were analysed, using qualitative methods to identify barriers and enablers to interpreter service use. RESULTS: For the years 2008-2010, approximately 10 742 consultations per year involved a non-Englishspeaking patient, yet in only approximately 74.8 (0.7%) consultations per year were interpreter services utilised. Analysis of focus groups and interviews identified four global themes that represented barriers for interpreter service utilisation; namely, practicalities, expectations, knowledge of service, and systems. DISCUSSION: The current use of interpreter services in PHC general practice appears to be significantly less than the need. In order to maximise health outcomes and reduce risk, strategies must be initiated to counter the barriers currently inhibiting interpreter service use, including adopting best practice policies

The composition of wage differentials between migrants and natives

We consider the role of unobservables, such as differences in search frictions, reservation wages, and productivities for the explanation of wage differentials between migrants and natives. We disentangle these by estimating an empirical general equilibrium search model with on-the-job search due to Bontemps et al. (1999) on segments of the labour market defined by occupation, age, and nationality using a large scale German administrative dataset. The native-migrant wage differential is then decomposed into several parts, and we focus especially on the component that we label “migrant effect”, being the difference in wage offers between natives and migrants in the same occupation-age segment in firms of the same productivity. Counterfactual decompositions of wage differentials allow us to identify and quantify their drivers, thus explaining within a common framework what is often labelled the unexplained wage gap

Adaptation to hummingbird pollination is associated with reduced diversification in Penstemon

This work is licensed under a Creative Commons Attribution 4.0 International License.A striking characteristic of the Western North American flora is the repeated evolution of hummingbird pollination from insect‐pollinated ancestors. This pattern has received extensive attention as an opportunity to study repeated trait evolution as well as potential constraints on evolutionary reversibility, with little attention focused on the impact of these transitions on species diversification rates. Yet traits conferring adaptation to divergent pollinators potentially impact speciation and extinction rates, because pollinators facilitate plant reproduction and specify mating patterns between flowering plants. Here, we examine macroevolutionary processes affecting floral pollination syndrome diversity in the largest North American genus of flowering plants, Penstemon. Within Penstemon, transitions from ancestral bee‐adapted flowers to hummingbird‐adapted flowers have frequently occurred, although hummingbird‐adapted species are rare overall within the genus. We inferred macroevolutionary transition and state‐dependent diversification rates and found that transitions from ancestral bee‐adapted flowers to hummingbird‐adapted flowers are associated with reduced net diversification rate, a finding based on an estimated 17 origins of hummingbird pollination in our sample. Although this finding is congruent with hypotheses that hummingbird adaptation in North American Flora is associated with reduced species diversification rates, it contrasts with studies of neotropical plant families where hummingbird pollination has been associated with increased species diversification. We further used the estimated macroevolutionary rates to predict the expected pattern of floral diversity within Penstemon over time, assuming stable diversification and transition rates. Under these assumptions, we find that hummingbird‐adapted species are expected to remain rare due to their reduced diversification rates. In fact, current floral diversity in the sampled Penstemon lineage, where less than one‐fifth of species are hummingbird adapted, is consistent with predicted levels of diversity under stable macroevolutionary rates
