2. 1. Gaze Following in Infancy : Mechanisms and Developmental Context

   Author : Kim Astor Währborg; Gustaf Gredebäck; Gergely Csibra; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Gaze following; Eye-tracking; Infants; Mechanisms; Culture; Joint visual attention; Social environment; Theories; Attention sharing; Psychology; Psykologi;

   Abstract : Few things are as fundamental to humans as the ability to share attention. It allows us to coordinate our actions with, and assimilate knowledge from, the actions of others with remarkable efficiency and accuracy. This ability emerges in infancy and sets the stage for all subsequent social development. READ MORE

4. 2. Understanding Neural Machine Translation : An investigation into linguistic phenomena and attention mechanisms

   Author : Gongbo Tang; Joakim Nivre; Rico Sennrich; Philipp Koehn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neural machine translation; Linguistic phenomena; Ambiguity; Long-range dependency; Morphology; Negation; Attention mechanisms; Interpretation; Computational Linguistics; Datorlingvistik;

   Abstract : In this thesis, I explore neural machine translation (NMT) models via targeted investigation of various linguistic phenomena and thorough exploration of the internal structure of NMT models, in particular the attention mechanism. With respect to linguistic phenomena, I explore the ability of NMT models to translate ambiguous words, to learn long-range dependencies, to learn morphology, and to translate negation—linguistic phenomena that have been challenging for the older paradigm of statistical machine translation.

5. 3. Attention capture by sudden and unexpected changes : a multisensory perspective

   Author : Erik Marsja; Jessica K. Ljungberg; Gregory Neely; Patrik Hansson; François Vachon; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attention Capture; Tactile; Auditory; Visual; Crossmodal; Bimodal; Distraction; Short-term memory; Attention; Psychology; psykologi;

   Abstract : The main focus for this thesis was cross-modal attention capture by sudden and unexpected sounds and vibrations, known as deviants, presented in a stream the same to-be-ignored stimulus. More specifically, the thesis takes a multisensory perspective and examines the possible similarities and differences in how deviant vibrations and sounds affect visual task performance (Study I), and whether the deviant and standard stimuli have to be presented within the same modality to capture attention away from visual tasks (Study II).

6. 4. Internalization mechanisms of cell-penetrating peptides : Structure-activity relationships, cellular distribution and membrane toxicity studies

   Author : Mats Hansen; Ülo Langel; Mark Lindsay; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-penetrating peptides; mechanisms; toxicity; structure-activity relationship; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

   Abstract : Transport of substances with pharmaceutical potential over the plasma membrane has been pushed a great step forward with the discovery of short cationic polypeptides, known as cell-penetrating peptides (CPP). Since then, the internalization mechanism and cargo delivery properties of CPPs has been extensively studied. READ MORE

7. 5. Social Policy in Development Contexts : Drivers, Mechanisms and Outcomes

   Author : Sebastian Sirén; Kenneth Nelson; Ann-Zofie Duvander; Olof Bäckman; Björn Halleröd; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social policy; social protection; political economy; welfare state; comparative politics; causal mechanisms; development; poverty; inequality; inclusive growth; partisan politics; sustainable development goals; global studies; Sociology; sociologi;

   Abstract : Economic growth amidst staggering inequality in many low- and middle-income countries makes the quest to end global poverty more topical than ever. Calls to leave no one behind in the course of development underscore the need to reconsider the role of policy frameworks in emerging economies. READ MORE
