This study examined changes in the sentence intelligibility scores of speakers with dysarthria in association with different signal-independent factors (contextual influences). This investigation focused on the presence or absence of iconic gestures while speaking sentences with low or high semantic predictiveness. The speakers were 4 individuals with dysarthria, who varied from one another in terms of their level of speech intelligibility impairment, gestural abilities, and overall level of motor functioning. Ninety-six inexperienced listeners (24 assigned to each speaker) orthographically transcribed 16 test sentences presented in an audio + video or audio-only format. The sentences had either low or high semantic predictiveness and were spoken by each speaker with and without the corresponding gestures. The effects of signal-independent factors (presence or absence of iconic gestures, low or high semantic predictiveness, and audio + video or audio-only presentation formats) were analyzed for individual speakers. Not all signal-independent information benefited speakers similarly. Results indicated that use of gestures and high semantic predictiveness improved sentence intelligibility for 2 speakers. The other 2 speakers benefited from high predictive messages. The audio + video presentation mode enhanced listener understanding for all speakers, although there were interactions related to specific speaking situations. Overall, the contributions of relevant signal-independent information were greater for the speakers with more severely impaired intelligibility. The results are discussed in terms of understanding the contribution of signal-independent factors to the communicative process.

Abstract Background Caesarean scar niche is increasingly being seen due to the rise in the number of caesarean sections worldwide. Indications and the ideal route for niche repair are still being researched. If the residual myometrium is less than 3 mm thick and potential fertility is needed, laparoscopy is the ideal surgical method for caesarean scar niche repair. The aim of this video presentation is to demonstrate techniques of identifying new anatomical landmarks during laparoscopic uterine niche repair. Results As seen in the video, Caesarean scar niche repair can be done in a step-by-step manner, with lateral bands serving as anatomical landmarks. Conclusions Lateral bands are a consistent anatomical landmark which identify the level and width of the uterine niche and thus simplify the laparoscopic repair making this a reproducible technique.

The authors investigated the impact of video speed on judging the duration of sport performance. In three experiments, they investigated whether the speed of video presentation (slow motion vs. real time) has an influence on the accuracy of time estimation of sporting activities (n1 = 103; n2 = 100; n3 = 106). In all three studies, the time estimation was more accurate in real time than in slow motion, in which time was overestimated. In two studies, the authors initially investigated whether actions in slow motion are perceived to last longer because the distance they cycled or ran is perceived to be longer (n4 = 92; n5 = 106). The results support the hypothesis that the duration of sporting activities is estimated more accurately when they are presented in real time than in slow motion. Sporting officials’ judgments that require accurate time estimation may thus be biased when based on slow-motion displays.

This research focuses on the symbols contained in the four Buavita video ads, namely Buavita Mix Berries, Buavita Kelapa, Buavita Mangga, and Buavita Jambu. These ad videos seem to be able to segment the community into a type of society. The research aims to prove the existence of certain symbols in the Buavita advertisement video as a practice of hegemony and perpetuating gender inequality. This research uses descriptive qualitative method with four theories of cultural studies as the theoretical basis. The results showed that Buavita's ad-style healthy lifestyle became a trick of capitalism in inviting people to consume symbols and make profits. The video presentation of Buavita's advertisement is also a medium for the perpetuation of the concept of the traditional gender role that positions women as domestic agents, passive and consumptive, while men as non-domestic, active, and productive agents.
