    This paper presents a first acoustic analysis of the stops and affricates of the mixed language Light Warlpiri (Australia). The results suggest that the Light Warlpiri phonological inventory consists of a voiced and voiceless series of stops and affricates, differentiated by Voice Onset Time (VOT) wordinitially and by Constriction Duration (CD) medially, by incorporating English-like VOT differentiation and Constriction duration differences found in Kriol and also in a number of traditional Indigenous Australian languages. Word-initially, stops from Warlpiri words pattern with English/Kriol voiced stops; medially with the ‘long’ stops in Kriol, /c/ being the exception in patterning with short /ʤ/, rather than the voiceless /ʧ/. This inventory allows speakers of Light Warlpiri to maintain sufficient phonemic contrasts to accommodate vocabulary items in Light Warlpiri sourced from English/Kriol as well as Warlpiri, the Indigenous Australian language that they also speak

    This paper presents a combined analysis of the perception and production study of the mixed language Light Warlpiri (Australia), which systematically combines elements of Warlpiri, Kriol and English. The perception and production results suggest that the Light Warlpiri phonological inventory consists of a voiced and voiceless series of stops and affricates, differentiated by Voice Onset Time (VOT) word-initially and by Constriction Duration (CD) medially, by incorporating English-like VOT differentiation and Constriction duration differences found in Kriol and also in a number of traditional Indigenous Australian languages. The results also show that Light Warlpiri speakers perceptually differentiate stops and fricatives at the same POA, but that voicing distinctions in fricatives are more difficult to discriminate than voicing distinctions in stops. The large phonological inventory of Light Warlpiri combines most features of the source languages, allowing speakers of Light Warlpiri to maintain sufficient phonemic contrasts to accommodate vocabulary items in Light Warlpiri sourced from English/Kriol as well as Warlpiri

    Digital technologies are fuelling the evolution of connected cities of the future. Our research in Copenhagen with organisations that are leading the digital transformation agenda, reveals that there are four critical and self-propelling factors that are essential to meeting the future demands of cities and its citizens

    On the expressiveness of forwarding in higher-order communication

    Abstract. In higher-order process calculi the values exchanged in communications may contain processes. There are only two capabilities for received processes: execution and forwarding. Here we propose a limited form of forwarding: output actions can only communicate the parallel composition of statically known closed processes and processes received through previously executed input actions. We study the expressiveness of a higher-order process calculus featuring this style of communication. Our main result shows that in this calculus termination is decidable while convergence is undecidable.
