A bstract We go “back to basics”, studying accelerating systems in 2 + 1 AdS gravity ab initio . find three classes of geometry, which we interpret by holographically their physical parameters. From these, construct stationary, point particles; one-parameter extensions the BTZ family resembling an black hole; and new solutions including a novel “BTZ geometry” not continuously connected hole as ...

Recognition, after 1, 3, 6, 15, and 30 intervening events, for CCC and CVC trigrams of low, medium, and high meaningfulness (M) was studied in the Shepard-Teghtsoonian paradigm. Correct recognition varied directly with M and inversely with number of intervening events. False recognition varied inversely with M and increased with total number of presentations. Confidence in correct recognitions ...

Product Based Workflow Design (PBWD) is one of the few scientific methodologies for the (re)design of workflow processes. It is based on an analysis of the product that is produced in the workflow process and derives a process model from the product structure. Until now this derivation has been a manual task and is therefore a time-consuming and error-prone exercise. Automatic support would enh...

Alignments provide a robust approach for conformance checking, which has been largely applied in various contexts such as auditing and performance analysis. Alignment-based conformance checking techniques pinpoint the deviations causing nonconformity based on a cost function. However, such a cost function is often manually defined on the basis of human judgment and thus error-prone, leading to ...

This thesis explores "meaningfulness" in videogames. Academics, journalists, and others who write about games often discuss the concept of meaning yet seldom define it clearly. I am focusing on a variation of this topic: what it means for a gaming experience to be meaningful--literally: full of meaning. Meaningfulness, as I define it, refers to the quality a videogame has when one considers it ...

The importance of meaningful work has been identified in scholarly writings across a range of disciplines. However, empirical studies remain sparse and the potential relevance of the concept of temporality, hitherto somewhat neglected even in wider sociological studies of organisations, has not been considered in terms of the light that it can shed on the experience of work as meaningful. These...
