In 1969, the newly elected coalition government of the Social Democratic Party (SPD) and Free Democratic Party (FDP) in West Germany announced plans to reform Paragraph 218, the law that regulated women's access to abortion. This announcement prompted a public debate in West Germany on the state's obligation to protect unborn life—a debate that continues today in reunified Germany. Through an analysis of key events in that debate between 1969 and 1989, this article makes a twofold argument. First it argues that despite West Germany's increasingly secular orientation, the Catholic Church exercised significant political influence with respect to abortion policy throughout the history of the Federal Republic. Second, it argues that the West German Church's participation in these debates exposed deep rifts within the Catholic community, which, in turn, contributed to the formation of a smaller, more activist, and conservative Church. This smaller Church has achieved a remarkable degree of political success in reunified Germany by mobilizing its conservative core constituency, embracing new arguments, and pursuing issue-specific alliances.

In 1962, the Federal Republic of Germany (frg) agreed to negotiate a guestworker agreement with Morocco in order to create guidelines for handling 4,000 so-called illegal Moroccan migrants, most of whom lived in North Rhine-Westphalia. Unlike other guestworker agreements, this one was not about recruitment, but rather it was designed to restrict migration from Morocco, legalise the stay of Moroccans already in the country, and establish guidelines for future deportations. Looking at the history of the West German-Moroccan Agreement from its start until its termination in 1973, this article provides a discussion of Moroccan labourers access to and legal status in West Germany, demonstrating how international and economic interests as well as cultural stereotypes of both Moroccans and Arabs shaped West German migration policies. In so doing, the article emphasises the West German federal and the North Rhine-Westphalian state governments’ different goals, revealing that the West German government was not a monolithic entity; it was in fact defined by multiple, sometimes contradictory, viewpoints and pressures.

The year 1971 marks the centenary of the death of Georg Gottfried Gervinus. This fact might seem to warrant attention only of antiquarians, since Gervinus appears in most textbooks (if at all) as a professor dismissed from the University of Göttingen for protesting the revocation of the Hanoverian constitution in 1837. But two facts about his reputation inspire greater attention. First, Gervinus was buried with unseemly haste by a host of unflattering necrologists, from Ranke on down, in the very year of the founding of the German Empire. Second, he has again achieved some attention recently as one of the few German democrats among the nineteenth-century professorate, thanks to publications in both East and West Germany. As an opponent of the “reactionary class compromise which underlay the unification of the Reich from above,” he has become an object of veneration in East Germany. In the west, the publication of his Introduction to the History of the Nineteenth Century and the subsequent Treason Trial against Gervinus has focused attention on the fate of those who sanctioned democratic revolution in the reactionary 1850's.3 In both cases, in obscurity and tendentious revival, Gervinus has been blamed or praised more for what he stood for than for what he was.

The Kootenay Arc located in SE B.C. has experienced more than one episode of tectonism, metamorphism and plutonism. The Mid-Jurassic to Eocene thermal history of the area has been investigated using K-Ar and 40/39 dating methods of biotite and muscovite; however there are no reliable hornblende dates from this area. This study will investigate two easterly stocks of the Nelson Plutonic Suite, the Mine and Wall stocks. Both of these have U-Pb zircon ages between 171 and 168 Ma but record a wide range of mica cooling and overprinting dates between 166 Ma in the west and 67 Ma in the east. 40Ar/39Ar age spectra for hornblende from 11 rocks in these stocks comprising a transect of the area, will aid in defining the higher temperature part of the thermal history. Previous attempts to prepare bulk hornblende separates were unsuccessful due to overgrowths and intergrowths of biotite, chlorite, plagioclase and K-feldspar. Part of this study involves testing the efficiency of SELFRAG disaggregation, which uses pulses of electrostatic power to break apart the biotite-hornblende-epidote granodiorite along mineral cleavage planes and grain boundaries. This should lead to higher purity mineral separates and better dates. Scanning Electron Microscopy (SEM) and Microprobe analysis analyse the separates looking for K-rich inclusions and the hornblendes variation in chemistry. Ca/K ratios are typical of igneous amphibole. Combined with previous K-Ar and 40/39 results for micas these hornblende dates should provide some insight into the history of the Next Creek fault and the thermotectonic history of the area.

Abstract. In this article, we reflect on 50 years of the journal Social Psychology. We interviewed colleagues who have witnessed the history of the journal. Based on these interviews, we identified three crucial periods in Social Psychology’s history, that are (a) the early development and further professionalization of the journal, (b) the reunification of East and West Germany, and (c) the internationalization of the journal and its transformation from the Zeitschrift für Sozialpsychologie to Social Psychology. We end our reflection with a discussion of changes that occurred during these periods and their implication for the future of our field.
