Previous research has shown that interruptions can lead to delays and errors on the interrupted task. Such research, however, seldom considers whether interruptions cause a change in how information is processed. The central question of this research is to determine whether an interruption causes a processing change. We investigate this question in a decision-making paradigm well-suited for examining the decision-making process. Participants are asked to select from a set of risky gambles, each with multiple possible stochastic outcomes. The information gathering process is measured using a mouse-click paradigm. Consistent with past work, interruptions did incur a cost: An interruption increased the time and the amount of information needed to make a decision. Furthermore, after an interruption, participants did seem to partially “restart” the task. Importantly, however, there was no evidence that the information gathering pattern was changed by an interruption. There was also no overall cost to the interruption in terms of choice outcome. These results are consistent with the idea that participants recall a subset of pre-interruption information, which was then incorporated into post-interruption processing.

This article compares Rudolf von Laban's and Mary Wigman's practices and theories of gestural flow with Walter Benjamin's theory of gesture as interruption. For Laban and Wigman, gesture mirrors a vitalist understanding of life that is based on the rediscovery of transhistorical continuities between human and cosmic energy. Benjamin's Brechtian gestures address inscriptions and manipulations of bodies, which provide comment on the conditions of society by subjecting to critique the essentializing aspects of historical and vitalist flow. Addressing in particular forms of vibration as both enriching and destabilizing the gestural from its margins, my article explores how vibratory energy indicates a self-reflexive theory of media, but also a revolutionary charge, in Benjamin; how it engenders a politically ambivalent process of transmission between dancers and audience in Laban; and how it becomes an actual mode of movement in Wigman. The historical inquiry contributes to a genealogy of vibration in contemporary dance.

Common arterial trunk with arch obstruction is a rare conotruncal abnormality. We report, with confirmatory images, a neonate with this anomaly and additional supracardiac partial anomalous pulmonary venous connection, as well as phenylketonuria.

In this paper, a batch arrival general bulk service queueing system with interruptedvacation (secondary job) is considered. At a service completion epoch, if the server findsat least ‘a’ customers waiting for service say ξ, heserves a batch of min (ξ, b) customers, whereb ≥ a. On the other hand, if the queue length is atthe most ‘a-1’, the server leaves for a secondary job (vacation) ofrandom length. It is assumed that the secondary job is interrupted abruptly and the serverresumes for primary service, if the queue size reaches ‘a’, during thesecondary job period. On completion of the secondary job, the server remains in the system(dormant period) until the queue length reaches ‘a’. For the proposedmodel, the probability generating function of the steady state queue size distribution atan arbitrary time is obtained. Various performance measures are derived. A cost model forthe queueing system is also developed. To optimize the cost, a numerical illustration isprovided.

This article provides an empirically grounded account of what happens when more persons than one talk at once in conversation. It undertakes to specify when such occurrences are problematic for the participants, and for the organization of interaction; what the features of such overlapping talk are; and what constraints an account of overlapping talk should meet. It describes the practices employed by participants to deal with such simultaneous talk, and how they form an organization of practices which is related to the turn-taking organization previously described by Sacks et al. 1974. This “overlap resolution device” constitutes a previously unexplicated component of that turn-taking organization, and one that provides solutions to underspecified features of the previous account.
