Active Labor Market Policy Evaluations: A Meta-Analysis
No full textThis paper presents a meta-analysis of recent microeconometric evaluations of active labor market policies. Our sample consists of 199 program estimates drawn from 97 studies conducted between 1995 and 2007. In about one-half of these cases we have both a short-term impact estimate (for a one-year post-program horizon) and a medium-term estimate (two-year horizon). We characterize the program estimates according to the type and duration of the program, the characteristics of the participants, and the evaluation methodology. Heterogeneity in all three dimensions affects the likelihood that an impact estimate is significantly positive, significantly negative, or statistically insignificant. Comparing program types, subsidized public sector employment programs have the least favorable impact estimates. Job search assistance programs have relatively favorable short-run impacts, whereas classroom and on-the-job training programs tend to show better outcomes in the medium-run than the short-run. Programs for youths are less likely to yield positive impacts than untargeted programs, but there are no large or systematic differences by gender. Methodologically, we find that the outcome variable used to measure program effectiveness matters. Evaluations based on registered unemployment durations are more likely to show favorable short-term impacts. Controlling for the outcome measure, and the type of program and participants, we find that experimental and non-experimental studies have similar fractions of significant negative and significant positive impact estimates, suggesting that the research designs used in recent non-experimental evaluations are unbiased.active labor market policy, program evaluation, meta-analysis

Gene loss and lineage specific restriction-modification systems associated with niche differentiation in the Campylobacter jejuni Sequence Type 403 clonal complex
No full textCampylobacter jejuni is a highly diverse species of bacteria commonly associated with infectious intestinal disease of humans and zoonotic carriage in poultry, cattle, pigs, and other animals. The species contains a large number of distinct clonal complexes that vary from host generalist lineages commonly found in poultry, livestock, and human disease cases to host-adapted specialized lineages primarily associated with livestock or poultry. Here, we present novel data on the ST403 clonal complex of C. jejuni, a lineage that has not been reported in avian hosts. Our data show that the lineage exhibits a distinctive pattern of intralineage recombination that is accompanied by the presence of lineage-specific restriction-modification systems. Furthermore, we show that the ST403 complex has undergone gene decay at a number of loci. Our data provide a putative link between the lack of association with avian hosts of C. jejuni ST403 and both gene gain and gene loss through nonsense mutations in coding sequences of genes, resulting in pseudogene formation
Polyakov loop distributions near deconfinement in SU(2) lattice gauge theory
No full textEngels J, Fingberg J, Weber M. Polyakov loop distributions near deconfinement in SU(2) lattice gauge theory. Zeitschrift für Physik, C: Particles and Fields. 1988;41(3):513-519.The distribution function of the Polyakov loop is investigated on a 163×3 lattice in the neighbourhood of the deconfinement transition of SU(2) gauge theory. We find, that well above the transition the distribution is a Gaussian; when the coupling approaches the critical point it is modified due to phase flip attempts of the system. Corresponding distributions for the plaquettes remain, however, Gaussian. For one coupling close to the transition we study the distributions on 83, 123 and 183×4 lattices and show that strong finite size effects are present. Using the maximum values of the Gaussian parts of the distributions we construct a more physical (and therefore scaling) order parameter whose critical exponent is in excellent agreement with the universality hypothesis
Die Römische Republik /
No full textWer sich für antike Geschichte interessiert, greift zu dieser knappen und gut lesbaren Geschichte der Römischen Republik, geschrieben von einem der bekanntesten Althistoriker Deutschlands. Jochen Bleicken (1926-2005) führt den Leser von der Zeit der Etrusker bis zum Ende der Republik, das die Herrschaft Caesars besiegelte. Alle wichtigen Phasen der republikanischen Geschichte entfalten sich: die Ständekämpfe, Aufstieg Roms zur Weltherrschaft - und die zugehörigen ungeheuren kriegerischen Auseinandersetzungen -, Ursachen und Beginn der inneren Krise seit den Gracchen, die Restauration unter Sulla und schließlich: die Auflösung der Republik und die Begründung der Monarchie. Aloys Winterling Jochen Bleicken, 1926-2005, war Professor für Alte Geschichte an der Universität Göttingen und u.a. Mitherausgeber von "Oldenbourg Grundriss der Geschichte" und der HISTORISCHEN ZEITSCHRIFT.Wer sich für antike Geschichte interessiert, greift zu dieser knappen und gut lesbaren Geschichte der Römischen Republik, geschrieben von einem der bekanntesten Althistoriker Deutschlands.
