This study investigates the landscape evolution and soil development in the loess area near Regensburg between approximately 6000-2000 yr BP (radiocarbon years), Eastern Bavaria. The focus is on the question how man and climate influenced landscape evolution and what their relative significance was. The theoretical background concerning the factors that controlled prehistoric soil erosion in Middle Europe is summarized with respect to rainfall intensity and distribution, pedogenesis, Pleistocene relief, and prehistoric farming. Colluvial deposits , flood loams, and soils were studied at ten different and representative sites that served as archives of their respective palaeoenvironments. Geomorphological, sedimentological, and pedological methods were applied. According to the findings presented here, there was a high asynchronity of landscape evolution in the investigation area, which was due to prehistoric land-use patterns. Prehistoric land use and settlement caused highly difIerenciated phases of morphodynamic activity and stability in time and space. These are documented at the single catenas ofeach site. In general, Pleistocene relief was substantially lowered. At the same time smaller landforms such as dells and minor asymmetric valleys filled up and strongly transformed. However, there were short phases at many sites, forming short lived linear erosion features ('Runsen'), resulting from exceptional rainfalls. These forms are results of single events without showing regional trends. Generally, the onset of the sedimentation of colluvial deposits took place much earlier (usually 3500 yr BP (radiocarbon) and younger) than the formation of flood loams. Thus, the deposition of flood loams in the Kleine Laaber river valley started mainly as a consequence of iron age farming only at around 2500 yr BP (radiocarbon). A cascade system explains the different ages of colluvial deposits and flood loams: as a result of prehistoric land use, dells and other minor Pleistocene landforms were filled with colluvial sediments. After the filling of these primary sediment traps , eroded material was transported into flood plains, thus forming flood loams. But at the moment we cannot quantify the extent ofprehistoric soil erosion in the investigation area. The three factors that controlled the prehistoric Iandscapc evolution in the Ioess area near Regensburg are as follows: 1. The transformation from a natural to a prehistoric cultural landscape was the most important factor: A landscape with stable relief was changed into a highly morphodynamic one with soil erosion as the dominant process of this change. 2. The sediment traps of the pre-anthropogenic relief determined where the material originated from soil erosion was deposited: either sedimentation took place on the slopes or the filled sediment traps of the slopes rendered flood loam formation possible. Climatic influence of any importance can only be documented as the result of land use in connection with singular and/or statistic events of heavy rainfalls. Without human impact, no significant change in the Holocene landscape would have been possible.

We present observations of the C270alpha carbon recombination line, 21 cm neutral hydrogen line and (CO)-C-12 (J = 1 --> 0) molecular line toward Cas A. A comparison of the distribution of recombination line optical depths over the face of Cas A with that of H I optical depths and molecular line emission favors the association of C270alpha regions with H I rather than molecular clouds. The association makes it possible to self-consistently determine several physical parameters of the clouds by combining the recombination line and 21 cm H I measurements.

Mulheres de todo o país avaliam o projeto de Constituição, e consideram que ainda há muito que conquistar. Contudo, a Coordenadora da Comissão, Maria A. Schumaher destaca os avanços obtidos pelas mulheres como a licença-maternidade de 120 (cento e vinte) dias, creche para crianças de 0 a 6 anos, a livre decisão do casal do número de filhos, o direito de amamentar adquirido pelas presidiárias e a discriminação por sexo, considerada crime inafiançável. A Presidente do Conselho da Mulher, Jaqueline Pitanguy, espera que o Plenário acate a proposta de que a família no Brasil é constituída também pela união estável, e assegure a plena igualdade de direitos e deveres entre os cônjuges. A representante do Movimento Mulher/BA, Maria Lina Silva, solicita a todo cidadão que cobrem dos parlamentares a efetivação das conquistas alcançadas. Adiada a votação do substitutivo que muda o regimento da Constituinte. Os líderes tentam chegar a um acordo para evitar o confronto dos grupos no plenário. O Deputado José Maria Eymael (PDC-SP) afirma que o momento é de entendimento, que atenda aos anseios de toda sociedade representada na Assembleia Nacional Constituinte (ANC). O Senador Fernando Henrique Cardoso (PMDB-SP) declara que após o Centrão atender ao seu pedido de adiamento da sessão, será realizado um trabalho de aprovação de medidas do regimento que viabilize uma votação mais célere e expresse realmente a vontade de todos. Segundo Roberto Cardoso Alves (PMDB-SP), o presidente Ulysses Guimarães, declarou ao conhecer alguns dos pontos críticos do Centrão, que muitos desses pontos também são considerados críticos pela esquerda, e isso facilitará um entendimento. O Deputado José Costa (PMDB-AL) considera fundamental a constatação que nenhum grupo tem 280(duzentos e oitenta) votos para decidir qualquer matéria Constitucional, então, será através da negociação que será elaborada a Constituição, equacionando temas como reforma agrária, reforma tributária e sistema de governo. A executiva do PFL se reuniu para traçar diretrizes. O vice-presidente do partido Eraldo Tinoco (PFL-BA) ficou encarregado de discutir com todos os parlamentares do PFL, para que o partido fixe posição sobre os pontos polêmicos do projeto de Constituição, como o sistema de governo. Discutiu-se também o substitutivo do Centrão que altera o regimento da Constituinte. O presidente do partido, o Senador Marco Maciel (PFL-PE) relata que assinou o documento do Centrão, mas não tinha conhecimento de outros objetivos do substitutivo além de mudar o regimento.

Syftet med uppsatsen är att undersöka hur en fackförening på en liten ort i Dalarna upplevt den stora arbetsmarknadskonflikt hösten 1909, känd som storstrejken. Hur dess medlemmar upplevde de påfrestningar de drabbades av och hur de klarade strejken och dess följder. Materialet består av mötesprotokoll från avdelningen samt den korrespondens som förekom mellan fackföreningen och förbundsledningen, och LO:s landssekretariat. I centrum för undersökningen står den under 1907 startade fackföreningen vid J.H. Munktells pappersbruk AB i Grycksbo, avdelning 332, tillhörande Grov- och Fabriksarbetarförbundet. Resultatet av undersökningen visar att fackföreningen kände en mycket begränsad entusiasm för storstrejken, beroende på dålig ekonomi och bristande tilltro till den egna förmågan. Vid strejkens början gick fackföreningen lojalt ut i strejk. Den fortsatta utvecklingen ledde till den inte ovanliga bilden med blockad och fridlysning av arbetsplatsen, strejkbryteri och ett med tiden ökande antal arbetare som gav upp strejken och sitt fackliga engagemang. För några få arbetare blev konsekvensen avsked. För fackföreningen blev konsekvensen ett drastiskt minskande medlemsantal.

Abstract. To date, terrestrial archives of long-term climatic change within the Arctic have widely been restricted to ice cores from Greenland and, more recently, sediments from Lake El’gygytgyn in northeast Arctic Russia. Sediments from this lake contain a paleoclimate record of glacialinterglacial cycles during the last three million years. Lowresolution studies at this lake have suggested that changes observed during Transition IV (the transition from marine isotope stage (MIS) 10 to MIS 9) are of greater amplitude than any observed since. In this study, geochemical parameters are used to infer past climatic conditions thus providing the first high-resolution analyses of Transition IV from a terrestrial Arctic setting. These results demonstrate that a significant shift in climate was subsequently followed by a rapid increase in biogenic silica (BSi) production. Following this sharp increase, bioproductivity remained high, but variable, for over a thousand years. This study reveals differences in the timing and magnitude of change within the ratio of silica to titanium (Si/Ti) and BSi records that would not be apparent in lower resolution studies. This has significant implications for the increasingly common use of Si/Ti data as an alternative to traditional BSi measurements.
