Understanding pragmatics [invited plenary talk]
No full textPragmatics is the discipline within linguistics that deals with actual language use. Language use is not only dependent on linguistic, that is grammatical and lexical knowledge, but also on cultural, situative and interpersonal contexts and conventions. One of the central aims of pragmatics is to research how context and convention – in their broadest sense – contribute to meaning and understanding. Thus, the social and cultural embedding of meaning is a central prerequisite for understanding pragmatics. Research in linguistic pragmatics deals with how speakers use their language(s) in various situations and contexts: what speakers do when they speak and why they do it. Pragmatics focuses on the actual language users, their communicative behaviour, their world and their point of view, in short, ‘the total human context of [language] use’ (Mey 1994: 3265). Pragmatics studies language and its meaningful use from the perspective of language users embedded in their situational, behavioural, cultural, societal and political contexts, using a broad variety of methodologies and interdisciplinary approaches depending on specific research questions and interests. Indeed, if we look at core domains of the discipline, we realize that linguistic pragmatics can be regarded as a transdiscipline that is relevant for, and has its predecessors in, many other disciplines such as Philosophy, Psychology, Ethology, Ethnology, Sociology and the Political Sciences. In this talk I take up this point and briefly discuss a selection of core issues of Pragmatics that were introduced into the field via these six disciplines (see Senft 2014).

RNDr. Tomáš Dvorˇák, CSc., Depart- ment of Software and Computer Science Education Abstract: Suffix tree and its variants are widely studied data structures that enable an efficient solution to a number of string problems, but also serve for implementation of data compression algorithms. This work explores the opposite approach: design of compression methods, based entirely on prop- erties of suffix graphs. We describe a unified construction algorithm for suf- fix trie, suffix tree, DAWG and CDAWG, accompanied by analysis of implicit suffix link simulation that yields two practical alternatives. Since the com- pression applications require maintaining text in the sliding window, an in- depth discussionof slidingsuffixgraphsisneeded. Fillinggapsin previously published proofs, we verify that suffix tree is capable of perfect sliding in amortised constant time. On the other hand, we show that this is not the case with CDAWG, thus resolving a problem of Inenaga et al.

Adaptation to photoperiod via dynamic neurotransmitter segregation
No full textChanges in the amount of daylight (photoperiod) alter physiology and behaviour1,2. Adaptive responses to seasonal photoperiods are vital to all organisms—dysregulation associates with disease, including affective disorders3 and metabolic syndromes4. The circadian rhythm circuitry is implicated in such responses5,6, yet little is known about the precise cellular substrates that underlie phase synchronization to photoperiod change. Here we identify a brain circuit and system of axon branch-specific and reversible neurotransmitter deployment that are critical for behavioural and sleep adaptation to photoperiod. A type of neuron called mrEn1-Pet17 in the mouse brainstem median raphe nucleus segregates serotonin from VGLUT3 (also known as SLC17A8, a proxy for glutamate) to different axonal branches that innervate specific brain regions involved in circadian rhythm and sleep–wake timing8,9. This branch-specific neurotransmitter deployment did not distinguish between daylight and dark phase; however, it reorganized with change in photoperiod. Axonal boutons, but not cell soma, changed neurochemical phenotype upon a shift away from equinox light/dark conditions, and these changes were reversed upon return to equinox conditions. When we genetically disabled Vglut3 in mrEn1-Pet1 neurons, sleep–wake periods, voluntary activity and clock gene expression did not synchronize to the new photoperiod or were delayed. Combining intersectional rabies virus tracing and projection-specific neuronal silencing, we delineated a preoptic area-to-mrEn1Pet1 connection that was responsible for decoding the photoperiodic inputs, driving the neurotransmitter reorganization and promoting behavioural synchronization. Our results reveal a brain circuit and periodic, branch-specific neurotransmitter deployment that regulates organismal adaptation to photoperiod change
