Time variable Earth’s gravity field from SLR satellites

The time variable Earth’s gravity field contains information about the mass transport within the system Earth, i.e., the relationship between mass variations in the atmosphere, oceans, land hydrology, and ice sheets. For many years, satellite laser ranging (SLR) observations to geodetic satellites have provided valuable information of the low-degree coefficients of the Earth’s gravity field. Today, the Gravity Recovery and Climate Experiment (GRACE) mission is the major source of information for the time variable field of a high spatial resolution. We recover the low-degree coefficients of the time variable Earth’s gravity field using SLR observations up to nine geodetic satellites: LAGEOS-1, LAGEOS-2, Starlette, Stella, AJISAI, LARES, Larets, BLITS, and Beacon-C. We estimate monthly gravity field coefficients up to degree and order 10/10 for the time span 2003–2013 and we compare the results with the GRACE-derived gravity field coefficients. We show that not only degree-2 gravity field coefficients can be well determined from SLR, but also other coefficients up to degree 10 using the combination of short 1-day arcs for low orbiting satellites and 10-day arcs for LAGEOS-1/2. In this way, LAGEOS-1/2 allow recovering zonal terms, which are associated with long-term satellite orbit perturbations, whereas the tesseral and sectorial terms benefit most from low orbiting satellites, whose orbit modeling deficiencies are minimized due to short 1-day arcs. The amplitudes of the annual signal in the low-degree gravity field coefficients derived from SLR agree with GRACE K-band results at a level of 77 %. This implies that SLR has a great potential to fill the gap between the current GRACE and the future GRACE Follow-On mission for recovering of the seasonal variations and secular trends of the longest wavelengths in gravity field, which are associated with the large-scale mass transport in the system Earth.

Adolescents’ willingness for intergenerational support: Relations to maternal expectations and mothers’ life satisfaction in 14 cultures

How is adolescents’ willingness for intergenerational support affected by parents’ expectations and parenting behavior? Does youths’ willingness for intergenerational support in turn affect parents’ well-being? The current study addresses these questions from a cross-cultural perspective, using data from connected samples of mother-adolescent dyads (N = 4162) from 14 diverse cultural contexts as part of the “Value of Children and Intergenerational Relations Study” (Trommsdorff & Nauck, 2005). The results are based on mixed model analyses (with culture as a random factor). Associations were investigated between family norms (expectations of support by adult children), parenting goals (obedience, independence) and parenting behavior (acceptance, control) reported by mothers and adolescents’ reports on willingness to support (help in household tasks, willingness to tolerate burdens in order to help their parents in case of accident, emotional support given to mothers and fathers). Across cultures, maternal expectations of adult children were positively related to adolescents’ reported household help and their current emotional support to mothers and fathers. Obedience, and control were positively related to the amount of adolescent help in the household, while independence and acceptance were related to a higher willingness to tolerate burdens as well as to higher emotional support given to the mother. Regarding associations between adolescents’ actual and intended intergenerational support with mothers’ life satisfaction, adolescents’ willingness to tolerate burdens was related to a higher maternal life satisfaction while adolescents’ reported household help was not. Adolescents’ current emotional support to fathers (but not to mothers) was also related to higher maternal life satisfaction. While most of the effects were stable across cultures (no significant random slope variance across cultural groups), some effects did significantly vary across cultures. Traditional-vs.-secular values as culture-level characteristics will be discussed as explanation for these culture-specific relations among mothers’ expectations, adolescents’ intergenerational support, and mothers’ life satisfaction.

The Five Senses in Medieval and Early Modern England

Edited by Annette Kern-Stähler, Beatrix Busse, and Wietse de Boer The essays collected in The Five Senses in Medieval and Early Modern England examine the interrelationships between sense perception and secular and Christian cultures in England from the medieval into the early modern periods. They address canonical texts and writers in the fields of poetry, drama, homiletics, martyrology and early scientific writing, and they espouse methods associated with the fields of corpus linguistics, disability studies, translation studies, art history and archaeology, as well as approaches derived from traditional literary studies. Together, these papers constitute a major contribution to the growing field of sensorial research that will be of interest to historians of perception and cognition as well as to historians with more generalist interests in medieval and early modern England.

Das Repertorium Academicum Germanicum (RAG). Ein digitales Forschungsvorhaben zur Geschichte der Gelehrten des alten Reiches (1250-1550)

This article aims at presenting an already existing research project. The Repertorium Academicum Germanicum (RAG) is supposed to be a "Who’s who" of the graduated and noble scholars of the late medieval Empire. It is designed to record biographical and social data of graduated theologians, jurists, physicians and Masters of Art as well as data of nobles from universities between 1250 and 1550. Furthermore, the project focuses on their examinations, networks, fields of activity in ecclesiastical and secular offices as well as their achievements and legacies (books, treatises, tombs etc). Right now, over 49.000 prosopographic entries are stored in the RAG database, partly available online (www.rag-online.org) and combined with digital maps (infographics), which already provide a basis for research in academic mobility determined by the top scholars of the time. In a next step, it should be possible to draw conclusions not only about personnel and knowledge transfer from university to society, its effects on political systems, daily life, the emergence of new occupational groups and professions, but also about cultural exchange within Europe.

Islamophobia as Reactive Co-Radicalization

Since 9/11, 2001, a new form of religious extremism has arguably emerged, one which paradoxically portrays itself as a counter to another perceived extremism regarded as a real and imminent threat. Within North America and Western Europe, as elsewhere, there is an upsurge of various forms of reactionary rhetoric and opposition expressed towards Islam and Muslims. An increase in extremist behaviour, even violence, is appearing from quarters opposed to, or varyingly fearful of, Islamic extremism if not Islam or Muslims. Islamophobia, as a manifestation of fear of an exclusionary Islam, manifests as exclusionary or negatively reactive behaviours with Muslims and Islam as the target. This article explores the idea that Islamophobia can be regarded as a manifestation of religious extremism and, further, that such extremism is construable as “reactive co-radicalization.” It focuses on two European cases – the 2009 Swiss ban on the building of minarets and the 2011 Norwegian massacre carried out by Anders Breivik – as examples of this “reactive co-radicalization.” This term, I suggest, is an apt denominator for the exclusionary reaction to the rising presence of Islam within otherwise secular, albeit nominally Christian, Western European and North American societies, among others.

Challenges in Collating Spirometry Reference Data for South-Asian Children: An Observational Study.

METHODS Spirometry datasets from South-Asian children were collated from four centres in India and five within the UK. Records with transcription errors, missing values for height or spirometry, and implausible values were excluded(n = 110). RESULTS Following exclusions, cross-sectional data were available from 8,124 children (56.3% male; 5-17 years). When compared with GLI-predicted values from White Europeans, forced expired volume in 1s (FEV1) and forced vital capacity (FVC) in South-Asian children were on average 15% lower, ranging from 4-19% between centres. By contrast, proportional reductions in FEV1 and FVC within all but two datasets meant that the FEV1/FVC ratio remained independent of ethnicity. The 'GLI-Other' equation fitted data from North India reasonably well while 'GLI-Black' equations provided a better approximation for South-Asian data than the 'GLI-White' equation. However, marked discrepancies in the mean lung function z-scores between centres especially when examined according to socio-economic conditions precluded derivation of a single South-Asian GLI-adjustment. CONCLUSION Until improved and more robust prediction equations can be derived, we recommend the use of 'GLI-Black' equations for interpreting most South-Asian data, although 'GLI-Other' may be more appropriate for North Indian data. Prospective data collection using standardised protocols to explore potential sources of variation due to socio-economic circumstances, secular changes in growth/predictors of lung function and ethnicities within the South-Asian classification are urgently required.

Heiligenspielrezeption in der Schweiz 1929: Das Bruderklausenspiel von Oskar Eberle

Based on Hansjürgen Linke’s study about the history of the reception of religious and secular medieval plays in twentieth-century Germany, the paper examines the respective situation in Switzerland. It focusses on the Bruderklausenspiel (1929), written and staged by Oskar Eberle. The director and scholar Oskar Eberle, and the Schweizerische Gesellschaft für Theaterkultur (SGTK) were the most influential supporters of the reception of religious plays in twentieth-century Switzerland. While in Germany the revival of medieval theatre emphasized a Renaissance of a former national importance, in Switzerland, the situation was very different. The revival of religious plays had a certain confessional background, and the political idea was to strengthen national self-confidence, and to confirm the nation’s historical neutrality concerning foreign affairs.
