We study the complexity of deciding if a given profile of incomplete votes (i.e., a profile of partial orders over a given set of alternatives) can be extended to a singlecrossing profile of complete votes (total orders). This problem models settings where we have partial knowledge regarding voters’ preferences and we would like to understand whether the given preference profile may be single-c...

Let V (n) denote the number of positive regular integers (mod n) that are ≤ n, and let Vk(n) be a multidimensional generalization of the arithmetic function V (n). We find the Dirichlet series of Vk(n) and give the extremal orders of some totients involving arithmetic functions which generalize the sum-of-divisors function and the Dedekind function. We also give the extremal orders of other tot...

Abstract How is the split black subject symbolized? The article attempts this question with its Lacanian-styled gap-filling (or -opening) method, using two clues — one from Big Bang Theory sitcom, and other Achebe’s Things Fall Apart . comes before imaginary, mirror stage, which begins child’s experience of Parental Other.

Abstract This article is concerned with the Lacanian subject of cyberwar and how Real network communication in post-Trump era experienced as horror. The centrality technological sublime practices self-divination to American political imaginary give this moment a properly cosmic spiritual scale. What returns are techno-horrors intersubjective dread capitalist which we fragmented manipulated by o...

Digitization of the communication medium has transformed mute, marginalized ‘audience’ into a heterogeneous and credible content ‘producer.’ Drawing on this dynamics operation digital media, it urged need to re-theorize ‘marginalization’ ‘race.’ Hence, paper critiques digital-media tool, blogs, using rhetoric-textual analysis method critical discourse for fictional text, Americanah. These metho...

In Zeiten angespannter Haushaltslagen und gleichzeitig zunehmender Finanzautonomie halten bereits seit geraumer Zeit Ideen und Steuerungsinstrumente des New Public Management im Hochschulbereich Einzug. Diese umfassen beispielsweise die Ausbringung der Haushalte als budgetierte Globalhaushalte sowie-insbesondere-die Verwendung einer Kosten-und Leistungsrechnung zur Befriedigung interner und ext...

Im Rahmen des von mehreren sächsischen Hochschulen initiierten Verbundvorhabens Videocampus Sachsen wird der Aufbau einer gemeinsamen Videoplattform angestrebt. Ein Systemleistungsvergleich dient dabei als technische Voraussetzung und Handlungsempfehlung für den Einsatz einer konkreten Portallösung. Ziel dieses Projektes ist die Katalogisierung von am Markt befindlichen Videoportallösungen sowi...
