Abstract Though episodes of lucidity (EL) in Alzheimer’s disease and related dementia (ADRD), reportedly more common near end of life, have significant implications for care, they are poorly understood due to underdeveloped methodological approaches for capturing and measuring these events. This prospective observational study addresses these gaps through audiovisual observation among persons with ADRD surrounding end of life to inform data-driven definitions for EL and distinguish EL from routine fluctuations in ADRD. Audiovisual observation is well-suited to addressing gaps in operationalization of EL, providing an objective data source to assess verbal and nonverbal communication, the primary means through which EL are evidenced. Our study is designed to establish optimal procedures for capturing audiovisual data of targeted populations and timeframes to maximize opportunities for detecting EL. Operationalization of EL will be informed by computational linguistic and behavioral-event coding of linguistic and non-linguistic communication features of EL and associated temporal qualities.

Integrating the arts with mixed methods research (MMR) presents untapped potential for innovative methodological approaches. Arts and MMR integration exists on a continuum, ranging from low-level (e.g., communicating about MMR using art) to high-level integration (e.g., interweaving arts-based and MMR approaches), and myriad art forms are available to facilitate concept formation, data collection, analysis, and representation. Given that a primary objective of the arts and MMR respectively is to explore and understand the complex social world, arts–MMR integration has potential to enable insights not possible through the use of either approach in isolation, and to present new opportunities for transformative social change. In this article, we explore such potentials and intersections philosophically and methodologically by way of four case examples framed by the newly conceptualized Art-MMR Integration Continuum, which ranges from communicative, data source, analytic, and conceptual integration.

With the rapid increase in the number of available digital texts in schools, new methodological approaches to studying writing development in education are now emerging. However, with new methodological approaches follow new epistemological challenges. In this article, I examine some of these challenges and discuss how they affect the role of computational linguistics within the field of educational writing research. The article is structured around three main sections. First, I position computational linguistics within the wider field of educational writing research with particular focus on L1 writing and K12 education. Second, I discuss to what extent methods from computational linguistics can provide us with new insights into different aspects of educational writing. Third, I discuss the potential of the concept of affordance to bridge between technology-centered and human-centered methodological approaches, and I relate this idea to recent theoretical developments in the digital humanities. Based on this discussion, I conclude the article with suggestions for possible directions in future writing research.

The goal of argumentation mining, an evolving research field in computational linguistics, is to design methods capable of analyzing people's argumentation. In this article, we go beyond the state of the art in several ways. (i) We deal with actual Web data and take up the challenges given by the variety of registers, multiple domains, and unrestricted noisy user-generated Web discourse. (ii) We bridge the gap between normative argumentation theories and argumentation phenomena encountered in actual data by adapting an argumentation model tested in an extensive annotation study. (iii) We create a new gold standard corpus (90k tokens in 340 documents) and experiment with several machine learning methods to identify argument components. We offer the data, source codes, and annotation guidelines to the community under free licenses. Our findings show that argumentation mining in user-generated Web discourse is a feasible but challenging task.

Theoretical Discovery

After all communication remains a bitter idea that one could communicate properly, and better, and more efficient, and lower overall costs. The idea that persists after any communication is that the communication was imperfect. Being imperfect, any communication is also a failure. The power of communication is the communication failure. The failure is to not express your-self perfect, or speak more or less than you should, or could not say everything, or being misunderstood. In essence, the failure and the primary means of communication to improve the communication would be expression, speech, discourse. Discourse can be verbal or non-verbal. In linguistic communication works the principle of general expression, the principle of strong effability (J. J. Katz). The range of expression through language we record influence of idea of ineffable: it is thought, content, feeling, feelings, expressiveness that cannot be expressed. Ineffable principle seems to be secondary. In fact, the natural state of the world is ineffability. Effability and Ineffability of communication are complementary principles. The power of communication is in communication failure. Perfection communication cancel communication, perfection does not allow self-reproduction of communication and therefore stimulate its implosion. Deficient communication process development support communication; communication failure is the communication power. Communication failure is a relatively late theoretical discovery of communication discipline. It follows that in a subsequent paper to investigate ”the principle of communication failure” that emerges from the research of several renowned experts in General Science Communication (C. R. Berger -1997; J. D. Peters; Noemi Marin - 2007).

Descriptive Method

The purpose of this study was to describe the forms of violations of the principle of cooperation by legislative officials and city level party leaders in West Sumatra on social media. This study used a qualitative-descriptive method. The data source in this study is in the form of speech in the Facebook status of officials and party leaders. The object of this research is the speech on Facebook of legislative and party leaders. Data collection was carried out by (1) printing screenings on Facebook of city-level legislative and party leaders in West Sumatra; (2) transcribing writings on facebook city level legislative and party figure officials in West Sumatra; (3) pay close attention to the writings on Facebook of city-level legislative and party figure officials in West Sumatra which are included in the section on language performance and politeness of communication; and (4) determine data included in the language performance section and politeness of written communication. Analyzing data is done with the aim of grouping data, analyzing data, and determining conclusions.Keywords: performance, facebook, linguistic, communication

Death Rattle

ObjectivesAt the end of life oral fluid intake is often reduced. Consensus about the most appropriate management for terminally ill patients with limited oral fluid intake is lacking. The objective of this study is to investigate to what extent the amount of fluid intake, preceding and during the dying phase, is related to the occurrence of death rattle and terminal restlessness.MethodsA multicentre prospective observational study was performed. Data on the occurrence of death rattle and terminal restlessness, fluid intake and opioid use of patients expected to die within a few days or hours were collected.Results371 patients were included. Death rattle was reported at least once in 40% (n=149) of patients during the dying phase. Death rattle occurrence was not associated with the amount of fluid intake during the days before dying. Terminal restlessness was reported in 26% of patients (n=96). Terminal restlessness was not associated with a lower amount of fluid intake during the days before dying. Terminal restlessness during the last 24 hours of life was associated with a higher amount of fluid (ie, >250 mL/day) during 48–25 hours before death.ConclusionsCaution with fluid intake to prevent development of death rattle does not seem to be necessary. Our study suggests that a higher amount of fluid intake during 48–25 hours before death may be associated with the occurrence of terminal restlessness during the last 24 hours of life. These results suggest that actively providing dying patients with artificial fluid may not be beneficial.
