Recently we reported that talkers modified their speech production strategies in noise as a function of whether their interlocutor could or could not be seen, i.e. face-to-face (FTF) or non-visual conditions (NV). Participants made greater auditory speech modifications (e.g. in terms of amplitude and F0) in NV condition, and greater visual speech modifications (in terms of inter-lip area) in FT...

Employees may continue to work remotely for a substantial amount of time, even after the end pandemic. Our established theories group processes and intergroup relations can help us understand these new ways working online experiences. However, there are key differences in computer-mediated face-to-face (FtF) groups. In this essay, I present some extant robust findings from computer communicatio...

Abstract This study aimed to investigate how having a student in leader role impacts group work dynamics (GWD) face‐to‐face (FTF) and online communication. A total of 144 pre‐intermediate English learners worked groups three on picture‐description task under one the four conditions: with or without FTF settings. All exchanges were recorded, transcribed, analyzed using GWD measuring instrument e...

Three glucosyltransferases (GTFs), which catalyze the formation of water-insoluble adherent glucans, and fructosyltransferase (FTF), which synthesizes fructans, are believed to contribute to the pathogenic potential of Streptococcus mutans. Study of the regulation of expression of GTF and FTF has been difficult because of the complexity and number of exoenzymes produced by this bacterium. By us...

Homopolysaccharide (glucan and fructan) synthesis from sucrose by sucrase enzymes in lactic acid bacteria (LAB) has been well studied in the genera Leuconostoc, Streptococcus and Lactobacillus. This study aimed to identify and characterize genes encoding glucansucrase/glucosyltransferase (GTF) and fructansucrases/fructosyltransferase (FTF) enzymes from genomic DNA of 'rare' Indonesian exopolysa...

Past research has suggested that decision-making groups, when communicating face-to-face (FtF), suffered from information sharing biases that affected the quality of the final decision: they tended to discuss previously-shared information before they started to discuss information not known to all, and discussed more of previously-shared than unshared information. In our study we examined these...

Hepatitis B virus (HBV) enhancer II (EnII) is a hepatotropic cis element which is responsible for the hepatocyte-specific gene expression of HBV. Multiple transcription factors have been demonstrated to interact with this region. In this study, the region from HBV nucleotides (nt) 1640 to 1663 in EnII was demonstrated to be essential for enhancer activity and to be another target sequence of pu...

Synthesis of single-wavelength temporal phase-shifting algorithms (PSA) for interferometry is well-known and firmly based on the frequency transfer function (FTF) paradigm. Here we extend the single-wavelength FTF-theory to dual and multi-wavelength PSA-synthesis when several simultaneous laser-colors are present. The FTF-based synthesis for dual-wavelength (DW) PSA is optimized for high signal...

This study investigated the effects of transformational and transactional leadership styles and communication media on team interaction styles and outcomes. Teams communicated through one of the following three ways: (a) face-to-face, (b) desktop videoconference, or (c) text-based chat. Results indicated that transformational and transactional leadership styles did not affect team interaction s...

Fructosyltransferase (FTF) enzymes have been characterized from various Gram-positive bacteria, but not from Lactobacillus sp. In a screening of 182 lactobacilli for polysaccharide production only one strain, Lactobacillus reuteri strain 121, was found to produce a fructan being a levan. Here we report the first-time identification and biochemical characterization of a Lactobacillus FTF enzyme....
