    Description: Late in a career of more than sixty years, Thomas Burch, an internationally known social demographer, undertook a wide-ranging methodological critique of demography. This open access volume contains a selection of resulting papers, some previously unpublished, some published but not readily accessible. Rejecting the idea that demography is simply a branch of applied statistics, his work views it as an autonomous and complete scientific discipline. When viewed from the perspective of modern philosophy of science, specifically the semantic or model-based school, demography is a balanced discipline, with a rich body of techniques and data, but also with more and better theories than generally recognized. As demonstrated in this book, some demographic techniques can also be seen as theoretical models, and some substantive/behavioral models, commonly rejected as theory because of inconsistent observations, are now seen as valuable theoretical models, for example demographic transition theory. This book shows how demography can build a strong theoretical edifice on its broad and deep empirical foundation by adoption of the model-based approach to science. But the full-fruits of this approach will require demographers to make greater use of computer modeling in the statement and manipulation of theoretical ideas, as well as for numerical computation.

    Description: Das Wachstum einer Volkswirtschaft und die Wohlfahrt einer Gesellschaft hängen wesentlich davon ab, dass ständig neue Unternehmen in die Märkte eintreten und mit neuen Ideen und Produkten für Wettbewerb sorgen. Sehr häufig werden sie von jungen Menschen gegründet. Im Zusammenhang mit einer alternden Bevölkerung werden daher vielfach abnehmende Impulse für das Gründungsgeschehen befürchtet und damit die negativen Effekte der Alterung betont. Dies verstellt allerdings den Blick auf mögliche positive Effekte der Alterung. Ziel der vorliegenden Studie ist es deshalb, ein möglichst umfassendes Bild über die grundlegenden Wirkungsmechanismen zwischen alternder Bevölkerung und Gründungsgeschehen zu vermitteln. Im Zentrum steht dabei eine fundierte empirische Analyse, die es erlaubt, die ökonomische Relevanz der entsprechenden Wirkungskanäle analytisch zu erfassen. Darauf aufbauend werden nationale und internationale Erfahrungen im Umgang mit dem Thema alternde Bevölkerung und Gründungen eruiert.

    Description: A City Against Empire is the history of the anti-imperialist movement in 1920s Mexico City. It combines intellectual, social, and urban history to shed light on the city’s role as an important global hub for anti-imperialism, exile activism, political art, and solidarity campaigns. After the Russian and the Mexican Revolution, Mexico City became a space and a symbol of global anti-imperialism. Radical politicians, artists, intellectuals, scientists, migrants, and revolutionary tourists took advantage of the urban environment to develop their visions of an anti-imperialism for the twentieth-century. These actors imagined national self-determination, international solidarity, and an emancipation from what they called “the West.” Global, local, and urban factors interacted to transform Mexico City into the most important hub for radicalism in the Americas. By weaving together the intellectual history of Mexico, the urban and social histories of Mexico City, and the global history of anti-imperialist movements in the 1920s, this books analyses the perfect storm of anti-imperialism in Mexico City.

    Description: We report results of Hubble Space Telescope observations from Ganymede's orbitally trailing side which were taken around the flyby of the Juno spacecraft on 7 June 2021. We find that Ganymede's northern and southern auroral ovals alternate in brightness such that the oval facing Jupiter's magnetospheric plasma sheet is brighter than the other one. This suggests that the generator that powers Ganymede's aurora is the momentum of the Jovian plasma sheet north and south of Ganymede's magnetosphere. Magnetic coupling of Ganymede to the plasma sheet above and below the moon causes asymmetric magnetic stresses and electromagnetic energy fluxes ultimately powering the auroral acceleration process. No clear statistically significant timevariability of the auroral emission on short time scales of 100s could be resolved. We show that electron energy fluxes of several tens of mW m−2 are required for its OI 1,356 Å emission making Ganymede a very poor auroral emitter.
    Description: Plain Language Summary: Jupiter's moon Ganymede is the largest moon in the solar system and the only known moon with an intrinsic magnetic field and two auroral ovals around its north and south poles. Earth also possesses two auroral ovals, which are bands of emission around its poles. This emission is also referred to as northern and southern lights. We use the Hubble Space Telescope to observe Ganymede's aurora around the time when NASA's Juno spacecraft had a close flyby at Ganymede. We find that the brightness of the northern and southern ovals alternate in intensity with a period of 10 hr. Additionally, we derive that an energy flux of several tens of milli‐Watt per square meter is necessary to power the auroral emission. This energy flux comes from energetic electrons accelerated in the vicinity of Ganymede.
    Description: Key Points: Hubble Space Telescope observations of Ganymede's orbitally trailing hemisphere on 7 June 2021 in support of Juno flyby. Brightness ratio of northern and southern auroral ovals oscillates such that the oval facing the Jovian plasma sheet is brighter. Oscillation suggests the aurora is driven by magnetic stresses coupling the moon's magnetic field to the surrounding Jovian plasma sheet.

    Description: This dataset consists of total air content (TAC) data from 326-416 m from the ice core drilled in 2018-19 at Skytrain Ice Rise (79.7417°S 78.545°W), Antarctica. The samples cover a period of approximately 5000-10000 years before present. Measurements were made on 10 cm long sections of core using a volumetric vacuum-extraction method built in house. No cut-bubble correction has been applied to these data.
