Annotated record of the detailed examination of Mn deposits from DSDP Site 33, Leg 5 (Core 5-33-2)

The proposed location of Site 33 was over north-south Magnetic Anomaly 10 (Pittman-Heirtzler, 32 million years) in order (a) to provide a basis for comparison of the age of the basal sediments with the age based on the magnetic anomaly, (b) to provide a basis for evaluation of relative movement along the Pioneer and Mendocino Fracture Zones, and (c) by being paired with Site 34, to provide comparison of basement materials for adjacent positive and negative magnetic anomalies.

Do Multiculturalism Policies Erode the Welfare State (Working Paper 33)

The past 30 years have witnessed a dramatic change in the way Western democracies deal with ethnic minorities. In the past, ethnic diversity was often seen as a threat to political stability, and minorities were subject to a range of policies intended to assimilate or marginalize them. Today, many Western democracies have adopted a more accommodating approach. This is reflected in the widespread adoption of multiculturalism policies for immigrant groups, the acceptance of territorial autonomy and language rights for national minorities, and the recognition of land claims and selfgovernment rights for indigenous peoples. We refer to these policies as “multiculturalism policies” or MCPs. The adoption of MCPs has been controversial, for two reasons. The first is a philosophical critique, which argues that MCPs are inherently inconsistent with basic liberal-democratic principles. Since the mid-1990s, however, this philosophical debate has been supplemented by a second argument: namely, that MCPs make it more difficult to sustain a robust Welfare State (hereafter WS). Critics worry that such policies erode the interpersonal trust, social solidarity and political coalitions that sustain a strongly redistributive WS. This paper reviews the reasons why critics believe that MCPs weaken political support for redistribution, and then examines empirically whether the adoption of MCPs has, in fact, been associated with erosion of the WS. This examination involves two steps: we develop a taxonomy of MCPs and classify Western democracies as “strong”, “modest” or “weak” in their level of MCPs. We then examine whether the strength of MCPs is associated with the erosion of the WS during the 1980s and 1990s. The evolution of the WS is measured through change in four indicators: social spending as a percentage of GDP; the redistributive impact of taxes and transfers; levels of child poverty; and the level of income inequality. We find no evidence of a consistent relationship between the adoption of MCPs and the erosion of the WS. Our analysis has limits, and we hope it stimulates further research. Nevertheless, the preliminary evidence presented here is clear: the case advanced by critics of MCPs is not supported. The growing ethnic diversity of Western societies has generated pressures for the construction of new and more inclusive forms of citizenship and national identity. The evidence in this paper suggests that debates over the appropriateness of multiculturalism policies as one response to this diversity should not be pre-empted by unsupported fears about their impact on the WS.

Direct experimental evidence for a multiparticle-hole ground state configuration of deformed Mg-33

The first direct experimental evidence of a multiparticle-hole ground state configuration of the neutron-rich Mg-33 isotope has been obtained via intermediate energy (400 A MeV) Coulomb dissociation measurement. The major part similar to(70 +/- 13)% of the cross section is observed to populate the excited states of Mg-32 after the Coulomb breakup of Mg-33. The shapes of the differential Coulomb dissociation cross sections in coincidence with different core excited states favor that the valence neutron occupies both the s(1/2) and p(3/2) orbitals. These experimental findings suggest a significant reduction and merging of sd-pf shell gaps at N similar to 20 and 28. The ground state configuration of Mg-33 is predominantly a combination of Mg-32(3.0,3.5MeV; 2(-), 1(-)) circle times nu(s1/2), Mg-32(2.5MeV; 2(+)) circle times nu(p3/2), and Mg-32(0; 0(+)) circle times nu(p3/2). The experimentally obtained quantitative spectroscopic information for the valence neutron occupation of the s and p orbitals, coupled with different core states, is in agreement with Monte Carlo shell model (MCSM) calculation using 3 MeV as the shell gap at N = 20.

Análise da composição florística de uma Área de Reserva Legal 33 anos após recomposição.

O objetivo deste estudo foi caracterizar a composição florística e a diversidade da vegetação espontânea em um sistema silvicultural, 33 anos após o plantio na região do Tapajós, visando estabelecer métodos sustentáveis para recomposição da Reserva Legal. Analisou-se a estrutura horizontal e a diversidade da vegetação espontânea. Foram identificados 483 indivíduos pertencentes a 81 espécies, 63 gêneros e 32 famílias. O Índice de Shannon- Weaver encontrado foi 3,72. Conclui-se que a vegetação espontânea estabelecida na área apresenta elevada riqueza e diversidade de espécies, evidenciando que o sistema silvicultural analisado é uma alternativa viável, podendo ser utilizado para a recomposição e manejo de Reserva Legal.
