News media literacy as a bridge
We address the relationship between negative news media coverage of Islam and antisemitic attitudes among Muslims as an indicator of cognitive Islamist radicalization. Conceptually grounded in Social Identity Theory and the concept of intergroup competitive victimhood, the study investigates the effects of exposure to negative news media coverage of Muslims and Islam on Muslims living in Germany ( N = 96). While exposure to negative news does not…
Afromontane forests and human impact after the African Humid Period
The SW highlands of Ethiopia are a key component in the evolution of modern humans. Yet, palaeoecological studies, essential to understand past human-vegetation relationships, are almost inexistent in this region. In this paper, we present an anthracological study of the Sodicho rock shelter, located at 1,930 m a.s.l. in the SW Ethiopian Afromontane forest zone, reconstructing the past woody vegetation since the end of the African Humid Period (c…
Iron Age plant subsistence in the Inner Congo Basin (DR Congo)
Around 400 bc , pottery- and iron-producing populations immigrated into the Inner Congo Basin (ICB) and subsequently spread upstream some major tributaries of the Congo River. Until recently, their subsistence was almost completely unknown. We present an archaeobotanical study of three sites in the ICB covering parts of the Early Iron Age (ca. 400 bc - ad 650) and of the Late Iron Age (LIA) as well as subrecent times (ca. ad 1300–2000). We studie…

Too dark to see? Explaining adolescents’ contact with online extremism and their ability to recognize it
Adolescents are considered especially vulnerable to extremists’ online activities because they are ‘always online’ and because they are still in the process of identity formation. However, so far, we know little about (a) how often adolescents encounter extremist content in different online media and (b) how well they are able to recognize extremist messages. In addition, we do not know (c) how individual-level factors derived from radicalization…

Journalistische Verantwortungsethik und sexueller Missbrauch
Sexueller Missbrauch ist ein häufig verborgener Missstand, der gerade dann ins öffentliche Bewusstsein rücken kann, wenn Betroffene den Weg in die Medienöffentlichkeit wählen. Um zu ergründen, welche Verantwortung Journalist*innen dabei gegenüber Betroffenen tragen, untersucht diese Studie die weitgehend unerforschten Medienwirkungen auf Betroffene, die im Zentrum von Berichterstattung standen. Vor dem theoretischen Hintergrund von Kepplingers Ko…
Online propaganda use during Islamist radicalization
While a plethora of previous studies have described extremist propaganda content that seeks to radicalize individuals, there has been a lack of research on how individuals who have become Islamists perceive and describe the propaganda they have used. To address this issue and to explore the personal drivers and circumstances of propaganda usage, we conducted in-depth interviews (n = 44) with radicalized Muslim prisoners and former Islamists in Ge…
Describing Perceptions of Media Influence among Radicalized Individuals
This study is the first to examine how Islamists in different phases of radicalization perceive media influence. Based on interviews with 34 Islamist prisoners and 9 former Islamists, we found that radicalized individuals perceived themselves as being immune to influence by the news media, which they generally perceived as being hostile. In contrast, they believed that the media had a relatively strong effect on the general public, on political a…

International Code for Phytolith Nomenclature (ICPN) 2.0
BACKGROUND: Opal phytoliths (microscopic silica bodies produced in and between the cells of many plants) are a very resilient, often preserved type of plant microfossil. With the exponentially growing number of phytolith studies, standardization of phytolith morphotype names and description is essential. As a first effort in standardization, the International Code for Phytolith Nomenclature 1.0 was published by the ICPN Working Group in Annals of…
Jugend - Medien - Extremismus
Online news media and propaganda influence on radicalized individuals
This study is the first to explore the twin influences of online propaganda and news media on Islamists. We conducted 44 in-depth interviews with cognitively and behaviorally radicalized Islamist prisoners in Austria as well as former Islamists in Germany and Austria. We found that online propaganda and news media had interdependent influences on Islamists’ rejections of non-Muslims and Western politics, as well as on their willingness to use vio…

News and Islamist Radicalization Processes
This study investigated how Muslims perceive negative news coverage of Islam and how these perceptions possibly contribute to radicalization processes. Utilizing qualitative interviews with former Islamists, Study 1 indicated that radicalized Muslims perceive a governmental infiltration of the media resulting in negative content. Analyses indicate that perceptual phenomena (hostile media, third person), negation, and anger play an important role …

In der Szene bist du wie in Trance. Da kommt nichts an dich heran.“ Entwicklung eines Modells zur Beschreibung von Medieneinflüssen in rechtsextremen Radikalisierungsprozessen
Angesichts der Zunahme rechtsextremer Gewalt in Deutschland drängt sich gerade aus einer kommunikationswissenschaftlichen Perspektive die bislang in der Forschung vernachlässigte Frage auf, welche Rolle unterschiedliche Medienangebote im Rahmen von Radikalisierungsprozessen spielen. Der vorliegende Beitrag will zur Schließung dieser Forschungslücke beitragen, indem auf Basis von qualitativen Interviews mit ehemals hochrangigen Führungskadern der …
Reziproke Effekte auf türkische Migranten. Eine Untersuchung zum Zusammenhang von sozialer Identität, Mediennutzung, Medienwahrnehmung und Medienwirkungen
This study examines the effects of group identification on the perception of media coverage about the respective group and the media effects that result from these perceptions. We transfer the model of individual reciprocal effects of Kepplinger (2007 An online survey with Turkish immigrants (N = 242) reveals that they are highly involved when their in-group becomes a topic of German media coverage. This involvement in turn leads to perceptions a…

First farmers in the Central African rainforest
Diversification, Intensification and Specialization
Early Plant Cultivation in the Central African Rain Forest
The Bantu expansion, a major topic in African archaeology and history, is widely assumed to correlate with the spread of farming, but archaeological data on the subsistence of these putative early Bantu speakers are very sparse. However, finds of domesticated pearl millet (Pennisetum glaucum) in southern Cameroonian archaeological sites, dated between 400 and 200 BC, open new perspectives on the history of agriculture in the Central African rain …
A new contribution to the Holocene vegetation history of the West African Sahel
Pits, graves and grains
Since 2003, a joint research project of the universities of Frankfurt and Tübingen (Germany) has explored the changing interrelationship of environment and culture in the forest-savanna regions of West and Central Africa. This paper provides the first archaeological and archaeobotanical results of three field seasons in the rainforest of southern Cameroun. Excavations were carried out at Bwambé Hill in the vicinity of Kribi at the Atlantic coast …

Phytolith taphonomy in the middle- to late-Holocene fluvial sediments of Ounjougou (Mali, West Africa)
In semi-arid ecosystems where lacustrine sediments are rare, bio-proxies preserved in fluvial deposits are needed to understand environmental changes. In this study, we evaluate the potential of phytoliths as a bio-proxy in the Yamé River’s deposits at Ounjougou (Mali, West Africa) covering the middle to late Holocene (7790–4000 cal. BP). In soils, phytolith assemblages result mainly from decomposition of local vegetation but in alluvial deposits…

Phytoliths in archaeology
Developing a Chronology Integrating Archaeological and Environmental Data from Different Contexts
At Ounjougou, a site complex situated in the Yamé River valley on the Bandiagara Plateau (Dogon country, Mali), multidisciplinary research has revealed a rich archaeological and paleoenvironmental sequence used to reconstruct the history of human-environment interactions, especially during the Late Holocene (3500–300 cal BC). Geomorphological, archaeological, and archaeobotanical data coming from different sites and contexts were combined in orde…

Seasonality change and the third millennium BP rainforest crisis in southern Cameroon (Central Africa)
The third millennium BP crisis of the central African rainforest is not sufficiently understood. The low resolution of most pollen profiles and a large plateau of the calibration curve aggravate the exact dating of the event, and its causal climatic parameters are debated. We present a high-resolution pollen profile from the swamp site Nyabessan in the southern Cameroonian rainforest, covering the period 3100-2300 cal yr BP. Between 3100 and 2500…
Early Bananas in Africa
Because the genus Musa is not indigenous to Africa, remains of bananas in African archaeological or geological contexts indicate cultivation of domesticated forms. During the past 10 years, at least two claims have been made for discovery of banana phytoliths in middle to late Holocene African contexts (Lejju et al. 2005, 2006, Mbida et al. 2000, 2001, 2006). These finds have not met with universal acceptance (cf. Mbida et al. 2005, Vansina 2003)…

Climate-induced fluvial dynamics in tropical Africa around the last glacial maximum?
The alluvia of the Ntem, Nyong and Sanaga fluvial systems in southern Cameroon recorded repeated fluvial activity fluctuations during the Late Pleistocene, including the last glacial maximum (LGM), the beginning of the African Humid Period and the northern hemispheric Bølling-Allerød. We applied a multi-proxy approach on alluvial stratigraphies dated between 22.4 and 13.0 cal ka BP, including remote sensing, sedimentological and morphogenetic met…
