On the Sexagenary Cycle of the Tibetans

This study examines Zuozhuan narrative accounts that conclude with evaluations ascribed to the “Gentleman” (junzi 君子). The Zuozhuan is one of the earliest extant Chinese works of narrative history, and in the past many scholars assumed that narrative accounts formed its core, dismissing subjective evaluations of those accounts, such as the Gentleman's comments, as secondary, later additions. This study demonstrates that narrative account plus Gentleman judgment function together as a unit, contending that these units were likely introduced into the Zuozhuan as such. It further proposes that the perception that the Gentleman's concluding comments were later, independent additions was likely influenced by the practice of capping narrative accounts with quotations borrowed from other sources, and furthermore, suggests that this perception may have led compilers on occasion to insert material between the narrative accounts and the Gentleman's evaluations of them.     

Die Einzelhandelsakteure im Spannungsfeld des Wettbewerbs und öffentlicher Vorgaben

Vielf?ltige, unterschiedlich starke und oft auch gegenl?ufig agierende Akteure und Interessenvertreter wirken auf das spezifische Standortmuster des Einzelhandels ein. Wie hat sich der Einzelhandel auf der Anbieter- und Nachfragerseite ge?ndert? Es fehlt nicht an Regelungswerken für den gro?fl?chigen Einzelhandel und Konzepten für einen gleichrangigen Standortwettbewerb zwischen den traditionellen Einkaufslagen und denen auf der Grünen Wiese. Wer sind die Standortakteure und wie stimmen sie sich ab? Wie l?sen sie die Standortkonflikte angesichts der Wettbewerbssituation? Welchen Beitrag leisten dazu staatliche und kommunale Vorgaben?     

Acheulean variability and hominin dispersals: a model-bound approach

Understanding the pattern of hominin dispersal is a fundamental component of Palaeolithic archaeology and palaeoanthropology. A widely held assumption is that bifacial handaxe (i.e. Acheulean or ‘Mode 2’) technologies evolved in Africa and dispersed into northern and western Eurasia via subsequent hominin migrations. To date, however, few formal tests of this hypothesis have been presented. Here, we use a combination of morphometrics, cultural transmission theory, and a dispersal model drawn from population genetics in order to test this hypothesis. The iterative founder effect (repeated bottlenecking) model is assumed to be supported if a significant inverse relationship is found between geographic distance from source along an estimated dispersal route and within-assemblage variance. The results of our analyses support the hypothesis that Acheulean technologies evolved in Africa and dispersed with migrating hominin populations into northern and western Eurasia under the assumptions of this iterative founder effect model. Based on our results we suggest that the occurrence of certain Mode 1 technologies such as those east of the Movius Line, and some assemblages assigned to the Clactonian of Britain, plausibly represent instances where effective population sizes in colonising populations dropped below levels where Mode 2 technologies could be maintained.     

Climate triggers: Rainfall anomalies,vulnerability and communal conflict in Sub-Saharan Africa

The mounting evidence for climate change has put the security implications of increased climate variability high on the agenda of policymakers. However, several years of research have produced no consensus regarding whether climate variability increases the risk of armed conflict. Many have suggested that instead of outright civil war, climate variability is likely to heighten the risk of communal conflict. In particular, erratic rainfall, which reduces the availability of water and arable land, could create incentives for violent attacks against other communities to secure access to scarce resources. Yet, whether groups resort to violence in the face of environmentally induced hardship is likely to depend on the availability of alternative coping mechanisms, for example through market transfers or state accommodation. This suggests that the effect of rainfall anomalies on communal conflict will be stronger in the presence of economic and political marginalization. We evaluate these arguments statistically, utilizing a disaggregated dataset combining rainfall data with geo-referenced events data on the occurrence of communal conflict in Sub-Saharan Africa between 1990 and 2008. Our results suggest that large negative deviations in rainfall from the historical norm are associated with a higher risk of communal conflict. There is some evidence that the effect of rainfall shortages on the risk of communal conflict is amplified in regions inhabited by politically excluded ethno-political groups.
