AbstractIn this concluding article I recall the early history of the Gaia mission, showing that the original science case and expectations of wide community interest in Gaia data have been met. The quarter-century long partnership involving some 1,000 scientists, engineers and managers in industry and academia is delivering a large, high-quality and unique data set which will underpin astrophysics across many sub-fields for years to come.

In the introduction of this book, Arthur Cohen states that The Shaping of American Higher Education is less a history than a synthesis. While accurate, this depiction in no way detracts from the value of the book. This work synthesizes the first three centuries of development of high-er education in the United States. A number of books detail the early history of the American collegiate system; however, this book also pro-vides an up-to-date account of developments and context for under-standing the transformation of American higher education in the last quarter century. A broad understanding of the book’s subtitle, Emergence and Growth of the Contemporary System, is truly realized by the reader.

Abstract The two main classes of vulcanized oil substitute or factice are heat-cured brown factice and cold-cured white factice. They were both introduced into the rubber industry at about the same time (1846–1847), the former variety by Anderson and the latter by Parkes. It has been stated (Twiss, Trans. Inst. Rubber Ind., 7, 234 (1931)) that Parkes first opened a proofing factory at Birmingham but that the business was shortly afterwards absorbed by Chas. Macintosh & Co. and transferred to Manchester. This probably dates the commencement of the use of white factice in proofings. The early history of the development of the use of brown factice on a works scale is more obscure. As the name implies, these vulcanized oils were used in the first place as ingredients which could economically substitute part of the crude rubber content of mixings, but as time went on it became apparent to compounders that these materials possessed intrinsic properties which made them almost indispensable in certain mixings, both for ease of manufacture and for high quality of the resultant article. The utility of factices in the general rubber trade is therefore in many respects analogous to that of reclaimed rubbers.

Accademia Del Cimento

The Royal Society was not the first scientific society, or organized academy for the promotion of science, to be founded, since it was preceded by the original Accademia del Cimento, which took its rise in 1657, but lived only ten years. The Royal Society is, then, the oldest corporate body of its kind to have enjoyed continuous existence until today. In a like way the Philosophical Transactions was not the earliest scientific periodical to come forth, since the first number of the Journal des Sçavans appeared, on 5 January 1665, two months before the first number of the Transactions . The Journal , however, while much concerned with scientific matters, including scientific books, dealt with the world of learning in general, including literary, legal and theological matters. Its pronouncements often led to stormy controversy, it had a troubled history and finally ceased to appear in 1790. The Transactions , except for a short break when it was replaced by Hooke’s Philosophical Collections , and for an interruption of three years that followed the landing of William of Orange and the flight of James II, has been published continuously from the issue of the first number dated 6 March 1664/5, the present year thus being the three hundredth anniversary of its beginning. Conspicuously connected with the first appearance of the Philosophical Transactions was Henry Oldenburg, a character very much to the fore in the early history of the Society.

We exploit a unique data set, combining rich experimental data with high-quality administrative data, to study dropout from the college track in Norway, and why boys are more likely to drop out. The paper provides three main findings. First, we show that family background and personal characteristics contribute to explain dropout. Second, we show that the gender difference in dropout rates appears both when the adolescents select into the college track and after they have started. Third, we show that different processes guide the choices of the boys and the girls of whether to drop out from the college track.

Low Metallicity

ABSTRACT Metal-poor stars are important tools for tracing the early history of the Milky Way, and for learning about the first generations of stars. Simulations suggest that the oldest metal-poor stars are to be found in the inner Galaxy. Typical bulge surveys, however, lack low metallicity ($\rm {[Fe/H]} \lt -1.0$) stars because the inner Galaxy is predominantly metal-rich. The aim of the Pristine Inner Galaxy Survey (PIGS) is to study the metal-poor and very metal-poor (VMP, $\rm {[Fe/H]} \lt -2.0$) stars in this region. In PIGS, metal-poor targets for spectroscopic follow-up are selected from metallicity-sensitive CaHK photometry from the CFHT. This work presents the ∼250 deg2 photometric survey as well as intermediate-resolution spectroscopic follow-up observations for ∼8000 stars using AAOmega on the AAT. The spectra are analysed using two independent tools: ULySS with an empirical spectral library, and FERRE with a library of synthetic spectra. The comparison between the two methods enables a robust determination of the stellar parameters and their uncertainties. We present a sample of 1300 VMP stars – the largest sample of VMP stars in the inner Galaxy to date. Additionally, our spectroscopic data set includes ∼1700 horizontal branch stars, which are useful metal-poor standard candles. We furthermore show that PIGS photometry selects VMP stars with unprecedented efficiency: 86 per cent/80 per cent (lower/higher extinction) of the best candidates satisfy $\rm {[Fe/H]} \lt -2.0$, as do 80 per cent/63 per cent of a larger, less strictly selected sample. We discuss future applications of this unique data set that will further our understanding of the chemical and dynamical evolution of the innermost regions of our Galaxy.

Five recently discovered documents reveal for the first time that eyeglasses with concave lenses for myopes were manufactured in Florence from at least the middle of the fifteenth century, about one hundred years before they were thought to be in use. This new evidence throws additional light on the development and early use of spectacles and on the early history of optical instruments and glass technology in general. These documents also reveal for the first time that Florence was the leading manufacturing center of high-quality eyeglasses and that spectacles had already become a prestigious item of personal adornment at least at the court of the dukes of Milan. This information should be of interest to historians of art and costume as well.

When the cult of relics developed in the mid-fourth century, very few tombs of saints whose remains were to be venerated in the centuries to come had been identified. This chapter presents the early history of the search for and finding of such graves, which started in the last decades of the fourth century. It seeks to explain the reasons which lay behind this process, focusing both on the needs of the congregation and the role of the discovery in church politics. It also analyses the sense of the literary pattern of inventio and tries to find out how much this pattern reflected reality. Finally, it presents a case study: a literary dossier of the discovery of the relics of Gervasius and Protasius by Bishop Ambrose of Milan in 386.

Recent work has called for sociologists to incorporate postcolonial theory into their toolkits to better understand the mechanics of race in the United States. The authors answer this call by showing how postcolonial and field theories can be bridged to explain how movements of the 1970s developed distinct visions of panethnicity. Drawing on published case studies, as well as a unique data set of pioneering “Asian American” and “Hispanic” movement magazines from the 1970s, the authors systematically compare how community leaders framed panethnic identities before they became widely institutionalized. The authors show that although Mexican Americans and Puerto Ricans could have developed a panethnic narrative centered on American imperialism, it was Asian Americans who constructed a postcolonial panethnic politics. In contrast, “Hispanic” stakeholders of the 1970s framed panethnicity more conservatively and at times patriotically. The authors contend that the different visions of panethnicity reflect the distinct colonial and imperial history of Asians and Hispanics in the United States as well as the position of Asian American and Hispanic panethnic leaders within and across the racial fields of the 1970s. This study suggests that panethnicity as a mobilizing identity narrative is politically flexible and amenable to different visions of racial equality. Moreover, the authors show how postcolonialism and field theory can be further synthesized to advance the study of panethnicity.

AbstractThis study investigates whether the existence or strength of any misreaction in the options market is affected by investor sophistication and investor sentiment. Based on a unique data set of the complete history of all transactions in the Taiwan options market, we find that individual investors exhibit significant misreaction to information and that this misreaction becomes stronger during periods of high investor sentiment. In addition, more active or aggressive individual investors always exhibit misreaction and do not learn from their past mistakes. Our empirical results are robust to alternative measures of investor sentiment and definitions of long- and short-term horizons.

Thomas Müntzer’s name is inseparably interwoven with the early history of the German Reformation. This reformer was active during the third decade of the sixteenth century and this mainly in Thüringen, an area in the eastern part of the German Empire belonging to the electorate of Saxony. As such it was to come early under the influence of the Lutheran reform movement initiated in Wittenberg.
