The ecological benefits of polyploidy are intensely debated. Some authors argue that plants with duplicated chromosome sets (polyploids) are more stress- resistant and superior colonizers and may thus outnumber their low ploidy conspecifics in more extreme habitats. Brachypodium distachyon (sensu lato), for example, a common annual grass in Israel and the entire Mediterranean basin, comprises three cytotypes of differing chromosome numbers that were recently proposed as distinct species. It was suggested that increased aridity increases the occurrence of its polyploid cytotype. Here, we tested at two spatial scales whether polyploid plants of B. distachyon s. l. are more frequently found in drier habitats in Israel. We collected a total of 430 specimens (i) along a largescale climatic gradient with 15 thoroughly selected sites (spanning 114- 954 mm annual rainfall), and (ii) from corresponding Northern (more mesic) and Southern (more arid) hill slopes to assess the micro- climatic difference between contrasting exposures. Cytotypes were then determined via flow cytometry. Polyploid plants comprised 90% of all specimens and their proportion ranged between 0% and 100% per site. However, this proportion was not correlated with aridity along the large- scale gradient, nor were polyploids more frequently found on Southern exposures. Our results show for both spatial scales that increasing aridity is not the principal driver for the distribution of polyploids in B. distachyon s. l. in Israel. Notably, though, diploid plants were restricted essentially to four intermediate sites, while polyploids dominated the most arid and the most mesic sites. This, to some degree, clustered pattern suggests that the distribution of cytotypes is not entirely random and calls for future studies to assess further potential drivers.
Narratives of Belonging
(2017)
Die Darstellungen genealogischer Netzwerke waren in der Antike Ausdruck der Weltsicht ihrer Erzähler, mit deren Hilfe Nähe und Distanz zwischen verschiedenen Gruppen und Völkern ausgedrückt und hergestellt werden konnte. Auch Paulus bedient sich genealogischer Argumente, um die Beziehung nicht-jüdischer Christus-Gläubiger zu Israel und ihrem Gott zu verdeutlichen. Es handelt sich um eine ethnozentrische Argumentation, deren Fokus aber gleichzeitig eindeutig theozentrisch ist.
When he founded Schocken Books in 1945, department store magnate, philanthropist, and publisher Salman Schocken (1877–1959) called his new American publishing business an imitation of its German predecessor, which had functioned from 1931 until 1938. He intended it to replicate the success of the Berlin Schocken Verlag by spiritually fortifying a Jewish community uncertain in its identity. The new company reflected the transnational transfer of people, ideas, and texts between Germany, Palestine/Israel, and the United States. Its success and near-failure raise questions about transnationalism and American Jewish culture: Can a culture be imposed on a population which has its own organs and agencies of cultural production? Had American Jewish culture developed organically to the specific place where several million Jews found themselves and according to uniquely American cultural patterns? The answers suggest that the concepts of transnationalism and cultural transfer complement each other as tools to analyze American Jewry in its American and Jewish contexts.
A Secular Tradition
(2021)
This article focuses on the social philosopher Horace Kallen and the revisions he made to the concept of cultural pluralism that he first developed in the early 20th century, applying it to postwar America and the young State of Israel. It shows how he opposed the assumption that the United States’ social order was based on a “Judeo-Christian tradition.” By constructing pluralism as a civil religion and carving out space for secular self-understandings in midcentury America, Kallen attempted to preserve the integrity of his earlier political visions, developed during World War I, of pluralist societies in the United States and Palestine within an internationalist global order. While his perspective on the State of Israel was largely shaped by his American experiences, he revised his approach to politically functionalizing religious traditions as he tested his American understanding of a secular, pluralist society against the political theology effective in the State of Israel. The trajectory of Kallen’s thought points to fundamental questions about the compatibility of American and Israeli understandings of religion’s function in society and its relation to political belonging, especially in light of their transnational connection through American Jewish support for the recently established state.

Eine achtköpfige Delegation der Universität Potsdam (UP) besuchte vom 18. bis 21. November 2018 die Tel Aviv University (TAU) in Israel. Die Kooperation zwischen beiden Einrichtungen wurde durch einen »staff exchange« intensiviert. So konnten Mitarbeiter*innen der UP ihren Gegenpart an der TAU kennenlernen und sich inhaltlich austauschen. Der vorliegende Bericht basiert auf Gesprächen mit drei der insgesamt fünf Bibliotheksdirektorinnen sowie zwei weiteren Kolleginnen aus dem Bereich Erwerbung und Katalogisierung. Dabei wurden unterschiedliche Themenbereiche aus dem Bibliothekswesen und die Sicht beziehungsweise der Stand dazu an der TAU und der UP angesprochen. Der vorliegende Bericht geht auf die Themenfelder Bibliothekssystem, Open Access und Bibliothek als Raum ein.

Von einer Säkularisierung in einem Land wie Israel zu sprechen, wo die Religion offensichtlich einen wichtigen Teil des öffentlichen Lebens darstellt, scheint widersprüchlich zu sein. Doch Israel befindet sich bedingt durch Globalisierung, Pluralisierung und Modernisierung an einem Scheideweg. Teile der israelischen Gesellschaft säkularisieren sich bereits. Die religiöse orthodoxe Vorherrschaft scheint zu bröckeln. Kann jedoch deswegen von einem Mentalitätswandel oder einer Säkularisierung des Staates gesprochen werden? Kann ein Säkularisierungsprozess in Israel erfolgreich sein? Wie muss ein säkularer Staat beschaffen sein, um den unterschiedlichen religiösen Denominationen die gleichen Möglichkeiten zu bieten? Welche Rolle spielen dabei die jüdische Diaspora, Einwanderungen und gesellschaftliche Minderheiten? Ziel der vorliegenden Arbeit ist es diese Fragen zu erörtern. Auch wenn die enge Verknüpfung von Nation und Religion im Judentum eine Säkularisierung scheinbar unmöglich macht, so erlaubt unter Bezugnahme der Konzepte von Säkularismus und Nationalismus im Kontext der historischen Entwicklungen des Judentums eine differenziertere Betrachtung dieser Verknüpfung. Durch die Nutzung von unterschiedlichen qualitativen Methoden, wie der hermeneutischen Methode zur Betrachtung der verschiedenen theoretischen Begriffe und der Analyse des Verhältnisses von Nation und Religion im Judentum; der Nutzung von Zeitungsartikel zur Aufarbeitung der aktuellen Debatten in der israelischen Gesellschaft; der Auswertung von Statistiken; sowie der Durchführung von Experteninterviews erlauben einen vielseitigen Zugang zum Forschungsgegenstand. Letztendlich soll aufgezeigt werden, dass sich Israel zwar zunehmend säkularisiert, aber vor verschiedenen Herausforderungen, wie dem gesellschaftlichen Pluralismus, der instabilen Sicherheitslage, sowie einem zunehmenden religiösen Nationalismus steht.

Ostracod shells from the archaeological site Gesher BenotYa'aqov (GBY) in the upper Jordan River Valley (Israel) were investigated to improve the understanding of the environmental conditions of the Acheulian occupation site during the early-mid Pleistocene transition (0.78 Ma). The diverse ostracod assemblage consists of 28 species. The distribution of most of the recorded species in the region today shows that the hydrological conditions at the early-mid Pleistocene transition were not fundamentally different from the modern ones. However, the predominance of Candona neglecta shells in the GBY sequence probably indicates cooler climatic conditions than today. Shells of Candona angulata in the artefact-richer upper half of the sequence suggest a slight salinity increase in the ancient Hula Lake from pure freshwater to slightly oligohaline conditions. This shift probably resulted from wetter conditions and a more stable lake environment with increased residence time of the lake water and stronger influence of evaporation. Shells of the brackish water ostracod Cyprideis torosa and the slightly halophilic Heterocypris sauna and Plesiocypridopsis newtoni were recorded only rarely suggesting that the lake maintained an outlet through the entire period represented by the GBY sequence. Shells of Gomphocythere ortali in GBY cycles 1 and 2 imply that a permanent freshwater stream existed close to the site. Humphcypris subterranea shells in cycles 3-5 provide further evidence that a tributary entered the lake from the south in contrast to the modern setting with the north-south flowing Jordan River at GBY. Statistical analysis of the quantitative ostracod data from GBY identified a group of samples from layers containing more abundant stone artefacts and another group of samples from layers with scarce artefacts. Samples from layers containing more abundant artefacts have relatively high abundances of C. angulata, Darwinula stevensoni and Physocypria kraepelini shells and include rare shells of Ilyocypris hartmanni, Ilyocypris salebrosa, Heterocypris incongniens and Pseudocandona sp. 2 which do not occur in the other samples. The presence of P. kraepelini and H. incongruens shells in artefact-richer sediments possibly indicates poor bottom water oxygenation in the ancient Hula lake sometimes during the periods of Acheulian occupation. However, more detailed studies are required to assess whether lower dissolved oxygen levels in the lake resulted from a slight lake level rise and possibly higher nutrient flux to the lake during wetter conditions or whether hominins already impacted lake's nutrient status by butchering at its shore or by burning of near-shore vegetation.

There Is No Return To Egypt
(2013)
Who are those Polish Jews, who in the wake of the Antizionist Campaign of the year 1968 left their home country and migrated to Israel? How do they, 40 years after these traumatic events, look back at their own history? Which development have they made in the Jewish State, a society torn by wars and inner political tensions? How do they live in Israel at the beginning of the 21st century? In the documentary There Is No Return To Egypt seven members of the Polish-Jewish migration cohort of the late 1960s, early 1970s and there todays environment are represented. These people, while being on camera in their mid-fifties till late seventies of age, allow an intimate view into their Israeli-Polish daily-life and into their world of memories. Interestingly, having survived the atrocities of the Shoah and being forced out of Poland some twenty years later, the older interviewees draw their very own conclusions for their further lives in Israel. In contrast, the younger interviewees deal very differently with the loss of their home and the break in their career life caused by the Antizionist Campaign. The personalities presented in this documentary have various professions: There is a successful musician, a former employee at the Israeli broadcasting service, and there are skilled workers. Their religious identities widely vary: from Jewish orthodox and national-religious to atheist to Judeo-Christian. The protagonists in There Is No Return To Egypt do also represent the political spectrum of Israel: from members of the chauvinist-militarist camp through to members of the peace movement. At the same time, the shooting locations in the documentary are important stages of life for the seven 1968ers: the home being decorated for Shabbat or for Israels national holiday Yom ha-atzmaut, the working place, an army museum, a Jewish settlement in the Palestinian Westbank, a Shoah memorial event at the university campus, a pop concert and a peace demonstration.
