Purpose The current study aimed to identify objective acoustic measures related to affective state change in the speech of adults with post-stroke aphasia. Method The speech of 20 post-stroke adults with aphasia was recorded during picture description and administration of the Western Aphasia Battery–Revised (Kertesz, 2006). In addition, participants completed the Self-Assessment Manikin (Bradley & Lang, 1994) and the Stress Scale (Tobii Dynavox, 1981–2016) before and after the language tasks. Speech from each participant was used to detect a change in affective state test scores between the beginning and ending speech. Results Machine learning revealed moderate success in classifying depression, minimal success in predicting depression and stress numeric scores, and minimal success in classifying changes in affective state class between the beginning and ending speech. Conclusions The results suggest the existence of objectively measurable aspects of speech that may be used to identify changes in acute affect from adults with aphasia. This work is exploratory and hypothesis-generating; more work will be needed to make conclusive claims. Further work in this area could lead to automated tools to assist clinicians with their diagnoses of stress, depression, and other forms of affect in adults with aphasia.

AbstractObjectives: How brain damage after stroke is related to specific clinical manifestation and recovery is incompletely understood. We studied cognitive reserve (CR) in stroke patients by two types of measurements: (i) objectively verifiable static proxies (i.e., education, occupational attainment), and (ii) subjective, dynamic proxies based on patient testimony in response to a questionnaire. We hypothesized that one or both of these types of CR measurements might correlate positively with patient cognitive performance during the post-acute and chronic phases of recovery. Method: Thirty-four stroke patients underwent neuropsychological assessment at 2, 6 and 24 months after stroke onset. In chronic stage at 24+ months, self-rating assessments of cognitive performance in daily life and social integration were obtained. CR before and after stroke was estimated using static proxies and dynamic proxies were obtained using the Cognitive Reserve Scale (CRS-Pre-stroke, CRS-Post-stroke). Results: CRS-Pre-stroke and CRS-Post-stroke showed significant mean differences. Dynamic proxies showed positive correlation with self-assessment of attention, metacognition, and functional ability in chronic stage. In contrast, significant correlations between static proxies and cognitive recovery were not found. Conclusions: Dynamic proxies of CR were positively correlated with patients’ perception of their functional abilities in daily life. To best guide cognitive prognosis and treatment, we propose that dynamic proxies of CR should be included in neuropsychological assessments of patients with brain damage.

The present study sought to examine the effect of dual language activation on L1 speech in late English–Austrian German sequential bilinguals, and to identify relevant predictor variables. To this end, we compared the English speech patterns of adult migrants to Austria in a code-switched and monolingual condition alongside those of monolingual native speakers in England in a monolingual condition. In the code-switched materials, German words containing target segments known to trigger cross-linguistic interaction in the two languages (i.e., [v–w], [ʃt(ʁ)-st(ɹ)] and [l-ɫ]) were inserted into an English frame; monolingual materials comprised English words with the same segments. To examine whether the position of the German item affects L1 speech, the segments occurred either before the switch (“He wants a Wienerschnitzel”) or after (“I like Würstel with mustard”). Critical acoustic measures of these segments revealed no differences between the groups in the monolingual condition, but significant L2-induced shifts in the bilinguals’ L1 speech production in the code-switched condition for some sounds. These were found to occur both before and after a code-switch, and exhibited a fair amount of individual variation. Only the amount of L2 use was found to be a significant predictor variable for shift size in code-switched compared with monolingual utterances, and only for [w]. These results have important implications for the role of dual activation in the speech of late sequential bilinguals.

AbstractFunctions are important in designing. However, several issues hinder progress with the understanding and usage of functions: lack of a clear and overarching definition of function, lack of overall justifications for the inevitability of the multiple views of function, and scarcity of systematic attempts to relate these views with one another. To help resolve these, the objectives of this research are to propose a common definition of function that underlies the multiple views in literature and to identify and validate the views of function that are logically justified to be present in designing. Function is defined as a change intended by designers between two scenarios: before and after the introduction of the design. A framework is proposed that comprises the above definition of function and an empirically validated model of designing, extended generate, evaluate, modify, and select of state-change, and an action, part, phenomenon, input, organ, and effect model of causality (Known as GEMS of SAPPhIRE), comprising the views of activity, outcome, requirement–solution–information, and system–environment. The framework is used to identify the logically possible views of function in the context of designing and is validated by comparing these with the views of function in the literature. Describing the different views of function using the proposed framework should enable comparisons and determine relationships among the various views, leading to better understanding and usage of functions in designing.

The performance of seven acoustic measures of cycle-to-cycle variations (perturbations) in the speech waveform was compared. All measures were calculated automatically and applied on running speech. Three of the measures refer to the frequency of occurrence and severity of waveform perturbations in special selected parts of the speech, identified by means of the rate of change in the fundamental frequency. Three other measures refer to statistical properties of the distribution of the relative frequency differences between adjacent pitch periods. One perturbation measure refers to the percentage of consecutive pitch period differences with alternating signs. The acoustic measures were tested on tape recorded speech samples from 41 voice patients, before and after successful therapy. Scattergrams of acoustic waveform perturbation data versus an average of perceived deviant voice qualities, as rated by voice clinicians, are presented. The perturbation measures were compared with regard to the acoustic-perceptual correlation and their ability to discriminate between normal and pathological voice status. The standard deviation of the distribution of the relative frequency differences was suggested as the most useful acoustic measure of waveform perturbations for clinical applications.

Picture Description

A multiple-probes variant of the multiple-baseline across-behaviors design was used to study the extent of generalization associated with syntax stimulation (SS) training. To assess whether acquisition of specific structures generalized across tasks, we used a specially designed sentence elicitation probe, Picture Description with Structure Modeling (PDSM; Fink et al., 1994). To assess whether training enhanced morphosyntactic production in connected speech, we used the coding scheme developed by Saffran, Berndt, and Schwartz (1989). Four subjects with chronic nonfluent aphasia were trained to produce active, passive, and embedded sentences using materials and procedures from the Helm Elicited Language Program for Syntax Stimulation (Helm-Estabrooks, 1981). These sentence structures were trained in successive phases with generalization probes administered before and after each phase. Three subjects with aphasia served as controls. Strong within-task generalization was observed and, in contrast to previous studies, generalization to the novel sentence elicitation task (PDSM). SS training did not yield measurable gains in narrative production.

ObjectivesMeat color is often seen by consumers as an indicator of freshness and wholesomeness. Nitrite-embedded (NE) packaging forms nitric oxide myoglobin, which imparts a bright red color similar to oxymyoglobin. However, limited research has determined the effects of NE packaging to improve the appearance of atypically dark cutting beef. Consumers’ perception of NE packaging ultimately determines its success in the market. Educating consumers through infographics can transfer knowledge more effectively than text alone, potentially being a useful method to introduce and simplify the complexity of NE packaging’s role in improving the surface color of beef steaks. The objectives of this study were to evaluate FreshCase® nitrite-embedded packaging’s effect on atypical dark-cutting beef steaks and to evaluate student consumer perception of nitrite-embedded packaging improving the surface color of beef before and after exposure to infographics containing equal content.Materials and MethodsAtypical dark-cutting (n = 13, pH 5.70 ± 0.09) and normal-pH (n = 13, pH = 5.57 ± 0.1) USDA Low Choice beef strip loins were selected 3 d postharvest. Atypical dark-cutting loins were cut into 2.54 cm thick steaks and randomly packaged in polyvinyl chloride film (PVC) or NE film. Normal-pH control loins were cut 2.54 cm and randomly packaged in PVC overwrap. Packages were placed in a coffin-style retail case under fluorescent lighting for 6 d. Instrumental color was observed every 24 h using a HunterLab MiniScan XE spectrophotometer. The color was determined as a* values and chroma. In the second objective, surveys using a ten-point Likert sliding scale (0 = not familiar at all, 10 = extremely familiar) were randomly allocated and emailed via Qualtrics to students enrolled in the Introduction to Animal Science course at Oklahoma State University. These surveys used a pre-questionnaire to evaluate students’ pre-perception of their knowledge of beef color and NE packaging. After the pre-perception questionnaire students were provided one of the following: a static infographic presented as a still image with annotated graphics, a 46 s video infographic with audio and animated graphics, or both infographic formats. A post-questionnaire followed exposure to students’ respective infographic to evaluate changes in the perception of knowledge.ResultsAtypical dark-cutting steaks treated in NE packaging had higher (P < 0.05, more red intensity) chroma and a* values compared to atypical dark-cutting steaks in PVC on d 4, 5, and 6. There was a significant difference (P < 0.05) in the students’ (n = 288) pre- and post-questionnaire self-assessment of their familiarity with NE packaging. Prior to randomly viewing infographics, students were less familiar (= 3.18) with NE packaging than after viewing infographics (= 6.46). However, there was no significant difference in perceptions (P = 0.22) between viewing the different infographic formats.ConclusionThe results suggest that NE packaging with consumer education can improve their perceptions and knowledge and enhance the appearance of atypical dark-cutting beef.

Summary Bulgaria ranks first in the world in incidence, morbidity and death associated with cerebrovascular disease. The aim of the study was to investigate, follow-up and register recovery of activities of daily living (using the toilet and maintaining personal hygiene) in patients with sequelae from cerebrovascular disease in a subacute stage, who underwent physiotherapy and rehabilitation. Sixty-one patients were included and followed up. They were given tailored physiotherapy and rehabilitation. This included kinesitherapy, occupational therapy and electrotherapy. All the patients filled in self-assessment questionnaires before and after the rehabilitation course. Major parameters were assessed, irrespective of the limb affected -dominant or non-dominant. Results were analyzed using the Wilcoxon rank test. At the end of the rehabilitation course, the Wilcoxon curves were driven to the right, confirming improvement concerning independence, irrespective of involvement of dominant or non-dominant limb.

The main purpose of the study predetermines the main issue of the article: to show the importance of formation of a culture of working with information among students during distance learning, which means the ability to evaluate, perceive information, prevent manipulation, distinguish truth from falsehood. The main task is to assess the existing and desired level of this competence, to develop an organizational model of its formation which consists of the following components: goals and objectives, pedagogical conditions and evaluation criteria. The model was implemented simultaneously at the Drahomanov National Pedagogical University and National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute” by teachers of humanities in experimental and control groups (16 people) in three stages: ascertaining, formative and final. A questionnaire and a self-assessment map of the formation of the culture of working with information were developed for the ascertaining stage; purposeful work with students was conducted (special tasks, discussion conversations, discussions) at the formative stage the results before and after the experiment were compared at the final stage in particular. Positive dynamics in the experimental group was noted, the average rate of formation increased. The proposed evaluation criteria – motivational, cognitive and activity ones have demonstrated practical value. It is advisable to recommend their use at other faculties. It is concluded that the organizational model is effective. The prospect of the study is the scientific substantiation of the implementation of the model among a wider range of students and the development of a distance specialized course.
