  1. 16. Sound perception and design in multimodal environments

    Author : PerMagnus Lindborg; Anders K. Friberg; Daniel Västfjäll; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sound; perception; design; multimodal; environment; soundscape; music; listening; crossmodal; psychoacoustics; psychophysiology; personality trait; emotion; appraisal; aesthetics; colour; correlation; regression; classification; sonification; Tal- och musikkommunikation; Speech and Music Communication;

    Abstract : This dissertation is about sound in context. Since sensory processing is inherently multimodal, research in sound is necessarily multidisciplinary. The present work has been guided by principles of systematicity, ecological validity, complementarity of  methods, and integration of science and art. READ MORE

  2. 17. Methods for Objective and Subjective Video Quality Assessment and for Speech Enhancement

    Author : Muhammad Shahid; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Video Quality Assessment; No-Reference Methods; Reduced-Reference Methods; Subjective Experiments; Speech Enhancement; Adaptive Gain Equalizer;

    Abstract : The overwhelming trend of the usage of multimedia services has raised the consumers' awareness about quality. Both service providers and consumers are interested in the delivered level of perceptual quality. The perceptual quality of an original video signal can get degraded due to compression and due to its transmission over a lossy network. READ MORE

  3. 18. Guided by Fear : Effects on attention and awareness

    Author : Nathalie Peira; Stefan Wiens; Nazanin Derakhshan; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Emotion; fear; attention; awareness; affective processing; heart rate; skin conductance; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Because the visual system has limited capacity, emotions such as fear may play an important role in guiding the selection of relevant input (LeDoux, 2000; Öhman & Mineka, 2001). The aim of the current thesis was to investigate how fear can guide the organism by influencing:  (I) attentional processes, (II) awareness of the visual input, and (III) affective processing independent of awareness.

  4. 19. Enabling Perceptions of Management Controls : Evidence from International Development Programs

    Author : Raymond Ndikumana; Tobias Johansson-Berg; Lili-Anne Kihn; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Enabling control; perceptions; development programs; PLS-structural equation modeling; empowerment; performance;

    Abstract : A key challenge for management accounting and control is the extent to which the control’s intentions correlate with how it is received and perceived by those who are subject to it. Building on Adler & Borys’ (1996) enabling and coercive bureaucracy, this thesis explores the role of perception; that is, local actors consider controls as enabling their work instead of privileging only those at the top.

  5. 20. The acquisition of contrast : a longitudinal investigation of initial s+plosive cluster development in Swedish children

    Author : Fredrik Karlsson; Kirk P. H. Sullivan; Peter E. Czigler; Marilyn M. Vihman; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; phonological contrast; speech development; place and manner of articulation; aspiration; structural complexity; acoustic cues; homonym production; Phonetics; Fonetik;

    Abstract : This Thesis explores the development of word-initial s+plosive consonant clusters in the speech of Swedish children between the ages of 1;6 and 4;6. Development in the word-initial consonant clusters is viewed as being determined by 1) the children’s ability to articulate the target sequence of consonants, 2) the level of understanding of which acoustic features in the adult model production are significant for the signalling of the intended distinction, and 3) the children’s ability to apply established production patterns only to productions where the acquired feature agrees with the adult target, to achieve a contrast between rival output forms.
