This article discusses the significance of international borders in Europe and Northeast Asia during the Cold War (1945–1989) and after. Using the concept of ‘moral hazard’, the article examines what happens when great powers frequently violate the borders of neighboring countries without suffering adverse repercussions. Norms of sovereignty and territorial integrity are viable only if large countries are willing to uphold them most of the time. The Soviet Union used or threatened to use military force against East European countries on (...) numerous occasions (1953, 1956, 1968, and 1980–1981) with impunity. The Russian Federation adopted a broadly similar policy toward neighboring countries that had been republics of the Soviet Union until 1991. Russian forces in Georgia, Moldova, Tajikistan, Belarus, and Ukraine served as instruments of Russian hegemony in those countries. Until 2014, Western governments made little or no effort to deter or counter Russian military encroachments in neighboring republics. By the principle of moral hazard, leaders in the Kremlin came to believe that they could act with a free hand in the former USSR. (shrink)

Despite the urgency of this issue, AI still struggles to represent social life. This article presents a comprehensive agent-based model that investigates status-power dynamics in groups. Kemper’s sociological status–power theory of social relationships, and a literature review on school children in middle youth, is its basis. The model allows us to investigate causation of the near-ubiquitous phenomenon that females have lower social status on average than males. Possible causes included in the model are children’s dispositional traits (kindness, beauty, and physical (...) power), schoolyard culture (social acceptability of fighting), behavioural strategy (amount of rough-and-tumble play) and the balance between public and dyadic sources of status. An agent-based model of a virtual schoolyard was created in which the children assemble in changing groups and mutually confer status. The status conferred upon a child modifies the status it holds. Rough-and-tumble is modelled as ambiguous: it is intended as a status conferral, but may be perceived as a power move. Running many trials of the model we found that in time, depending on the parameter settings, a gender-based status gap emerged. Rough-and-tumble play had more impact on emergent status differences than did physical power differences. Social acceptability of fighting also strongly moderated the resulting status gap. Placing more weight on dyadic relationship could alleviate status loss. All these model behaviours are in line with empirical findings of child behaviour studies at schools. They have face validity for social status issues in the adult world. We conclude from this that this kind of agent-based model merits use in studying the status–power dynamics of other issues in child behaviour, or indeed in social behaviour in general. (shrink)

Citizen event reporting (CER) attempts to leverage the eyes and ears of a large population of citizen sensors to increase the amount of information available to decision makers. When deployed in an environment that includes hostile elements, foes can exploit the system to exert indirect control over the response infrastructure. We use an agent-based model to relate the utility of responses to population composition, citizen behavior, and decision strategy, and measure the result in terms of a force multiplier. We show (...) that CER can lead to positive force multipliers even with a majority of hostile elements in the population. When reporter identity is known, a reputation system that keeps track of trustworthy reporters can further increase the force multipliers. (shrink)

Communism is not a reaction against the failure of the nineteenth century to organize optimal economic output. It is a reaction against its comparative success. It is a protest against the emptiness of economic welfare, an appeal to the ascetic in us all... The idealistic youth play with Communism because it is the only spiritual appeal which feels to them contemporary.
