Sofiia Andrukhovych’s Felix Austria: the postcolonial neo-Gothic and Ukraine’s search for itself

ABSTRACT

Sofiia Andrukhovych’s 2014 novel Felix Austria (Feliks Avstriia) became Ukraine’s most critically acclaimed and commercially successful work of literature published in the immediate aftermath of the Euromaidan revolution of 2013–14. It combined an ambitious historical reconstruction of daily life in the year 1900 in a mid-size city in the Habsburg-ruled part of Ukraine and an engaging plot skilfully employing multiple devices associated with the Gothic tradition, especially in its latter-day and postmodernist reinterpretations. The novel’s success is especially telling in the context of the rising interest in the Gothic in Ukrainian culture. Told by an unreliable narrator, the novel prompts readers to interrogate their assumptions. In the context of Ukraine, it is particularly subversive in its engagement with the nostalgic myth of the Habsburg Empire as a multi-ethnic utopia of tolerance, and by implication it challenges all imperial myths. The novel’s emphasis on the quest for (self-)discovery strongly resonated with readers in the context of a socio-political crisis, which highlighted the relevance of the distinct postcolonial overtones in its message.     

Preemptive scheduling on two identical parallel machines with a single transporter

We consider a scheduling problem on two identical parallel machines, in which the jobs are moved between the machines by an uncapacitated transporter. In the processing preemption is allowed. The objective is to minimize the time by which all completed jobs are collected together on board the transporter. We identify the structural patterns of an optimal schedule and design an algorithm that either solves the problem to optimality or in the worst case behaves as a fully polynomial-time approximation scheme.     

Single machine scheduling with general positional deterioration and rate-modifying maintenance

We present polynomial-time algorithms for single machine problems with generalized positional deterioration effects and machine maintenance. The decisions should be taken regarding possible sequences of jobs and on the number of maintenance activities to be included into a schedule in order to minimize the overall makespan. We deal with general non-decreasing functions to represent deterioration rates of job processing times. Another novel extension of existing models is our assumption that a maintenance activity does not necessarily fully restore the machine to its original perfect state. In the resulting schedules, the jobs are split into groups, a particular group to be sequenced after a particular maintenance period, and the actual processing time of a job is affected by the group that job is placed into and its position within the group.     

Analysis of the Effects of Communication and Surveillance Facility Service Outages on Traffic Separations

This study examines air traffic separations in the service volumes of communication and surveillance facilities that experienced service outages. The data sample consists of 338 unscheduled service outages that happened in 2010 and 2011 at facilities located in the vicinity of 15 major traffic hubs. For each outage, radar track data were collected and used to calculate traffic separations during the period of 30 minutes before to 30 minutes after an outage. Then, the separation index, which indicates the percentage of horizontal separation retained between two aircraft at the same altitude, was estimated. The separation index and loss of separation events were analyzed using lognormal and negative binomial regression models. The results suggest that the count of separation events peaks during the 15 minutes after an outage. In addition, traffic collision avoidance system resolution advisory (TCAS RA) encounters and Category A separation events are 1.31 times more likely during the 30 minutes following the beginning of a service outage, as compared to the 30 minutes before the outage, for both types of facilities. Also, the separation index values are 19% lower following a surveillance facility outage and 4% lower following a communication facility service loss. This study provides evidence that unscheduled service outages of air traffic management facilities are associated with lost or reduced traffic separations and thus can be considered precursors to hazardous loss of separation events.     

Maximin play in completely mixed strategic games

Since the seminal paper of Nash (Proc Natl Acad Sci USA 36:48–49, 1950) game theoretic literature has focused mostly on equilibrium and not on maximin (minimax) strategies. In a recent paper of Pruzhansky (Int J Game Theory 40:351–365, 2011) it was shown that under fairy general conditions maximin strategies in completely mixed games can guarantee the same expected payoff as completely mixed Nash equilibrium strategies. Based on this finding, the current paper argues that maximin strategies have important properties. For instance, maximin strategies may refine Nash equilibria in subjective mixed strategies. Further, Bayesian rationality of the players may favor maximin strategies more often than Nash equilibrium strategies. The paper concludes with several suggestions for further experimental research that may shed more light on whether maximin behavior can explain reality better than Nash equilibrium.     

The Pleasures and Problems of Leonid Osyka’s Zakhar Berkut: Poetic Cinema and Its Limits

Abstract

This article discusses the aesthetic and sociopolitical contexts of Zakhar Berkut, a 1972 film by the Ukrainian director Leonid Osyka, one of the leading figures of Ukrainian poetic cinema. An ambitious adaptation of a canonical nineteenth-century historical novel by Ivan Franko, it was conceived as the first big-budget Ukrainian historical film since World War II. An unusual and controversial hybrid of poetic cinema techniques and mainstream filmmaking oriented towards a mass audience, it became the last work of Ukrainian poetic cinema released before a severe state-sponsored crackdown brought the heyday of this film school to an abrupt end.
