The Genus Homo: Origin, Speciation and Dispersal
2011
The taxonomical interpretation of the fossil record of our own genus Homo is still highly controversial. In spite of obvious major advances concerning the acquisition, analysis and interpretation of the fossil specimens there currently remain unbridgeable disagreements concerning the origin, speciation and dispersal of our genus. The polarized positions result foremost from different methodological approaches for species recognition (e.g., Tattersall 1986; Wolpoff and Caspari 1997; Schwartz 2000a; Wiesemuller et al. 2003; Jobling et al. 2004; Rothe and Henke 2006). Beside the Multiregional Evolutionary Model (MRE) there are different Recent African Origin Models (RAOMs) with varying numbers…
Chemical variability in volcanic gas plumes and fumaroles along the East African Rift System: New insights from the Western Branch
2022
The origin of magmatic fluids along the East African Rift System (EARS) is a long-lived field of debate in the scientific community. Here, we investigate the chemical composition of the volcanic gas plume and fumaroles at Nyiragongo and Nyamulagira (Democratic Republic of Congo), the only two currently erupting volcanoes set on the Western Branch of the rift. Our results are in line with earlier conceptual models proposing that volcanic gas emissions along the EARS mainly reflect variable contributions of either a Sub-Continental Lithospheric Mantle (SCLM) component or a Depleted Morb Mantle (DMM) component, and deeper fluid. At Nyiragongo and Nyamulagira, our study discards a major contrib…
Diversity and Life Writing in the Transnational Classroom
2018
For this chapter, Alfred Hornung locates the origin of Germany’s diversity studies in the postwar era, during which Germany experienced gradual transculturation, especially due to the presence of African American soldiers, but also due to the appearance of American cultures in the media, the introduction of American studies in German universities, and the teaching of multi-ethnic authors in American literature courses. On the basis of international pedagogical experience, Hornung demonstrates that life writing lends itself particularly well to the representation and recognition of diversity and suggests how inclusion can be furthered. The focus of this chapter’s transnational classroom comp…
La predicción de la satisfacción con la vida en personas mayores de Angola: el efecto moderador del género
2014
ResumenExiste abundante investigación que ha estudiado la satisfacción vital en personas mayores y ha encontrado evidencia empírica de sus mejores predictores. Cuando se estudia la satisfacción con la vida de las personas mayores y sus predictores se hallan diferencias en función del género incluyendo, por ejemplo, las interacciones con la viudedad. En este contexto, el presente estudio se ha centrado en los siguientes objetivos: (1) poner a prueba la invarianza en función del género de una medida de satisfacción con la vida, (2) predecir la satisfacción vital usando varias variables relacionadas con el proceso de envejecimiento y (3) poner a prueba el potencial efecto moderador del género …

El acceso de los hijos de inmigrantes a la Educación Superior en España ¿una cuestión de origen étnico o de origen social?
2021
El presente trabajo se enmarca dentro de los estudios sobre la Dimensión Social de la Educación Superior (DOES). En él se estudia el peso que la posición socioeconómica tiene en el acceso a la Educación Superior de las segundas generaciones en España. Para ello analizamos la probabilidad de que los estudiantes con antecedentes migratorios y diferentes orígenes socioeconómicos realizaran estudios terciarios durante la segunda década del siglo XXI en contraste con la población autóctona de nuevo ingreso. En nuestros resultados encontramos diferencias significativas en el acceso a la universidad entre los jóvenes con edades comprendidas entre los 18 y 21 años, pertenecientes a las segundas gen…
Chinese Green Tea in Mali, Cultural Mobility and African Agency in the Global South
2020
Abstract The paper offers insights from ethnographic research that reach beyond general assumptions of the working of globalization, especially in the Global South. It examines the ways in which the arrival of products made in China, namely green tea, has influenced the everyday of people in Mali, modifying consumption practices and the business landscape. Chinese green tea, which is known in the Sahel countries of West Africa since the 19th century, has gradually found more and more consumers in Mali, so that from the 2000s onwards tons of green tea arrive every month in the country. Most Malians, the paper shows, consume green tea several times a day and identify with the beverage to such…
