Supporting presence in collaborative environments by haptic force feedback

An experimental study of interaction in a collaborative desktop virtual environment is described. The aim of the experiment was to investigate if added haptic force feedback in such an environment affects perceived virtual presence, perceived social presence, perceived task performance, and task performance. A between-group design was employed, where seven pairs of subjects used an interface with

Whom and What to Fight? Some Notes and Queries on Indian Farmers Collective Action under Liberalisation and Globalisation

Farmers’ movements arose in Tamil Nadu, Punjab, Karnataka, Maharashtra and U.P in the early 1970s as a result of the broad state intervention in commercial agricultural development, especially the green revolution technology and electrified pump-irrigation. Since the state had already organised farmers in service cooperatives, farmers’ movements took an explicitly political form agitating for bett

Variations on the Evidence-Based Timeline Retrospective Method A Comparison of Two Cases

Project retrospectives can be a powerful tool for process improvement through obtaining new insights. However pure experience-based reflections may lead to incorrect conclusions. Our method, evidence-based timeline retrospectives (EBTR), mitigates this risk by providing a pre-generated timeline that visualises project history based on evidence rather than relying on subjective opinions and biased

The Stollberg ore field - petrography, lithogeochemistry, mineral chemistry, and ore formation

Popular Abstract in Swedish Denna studie har gått ut på att relatera litogeo- kemin (= kemin i bergarter) kring Stollbergs järn- och sulfidmalmsfält i Bergslagen till mineralogi och geologisk utveckling. Bergarterna kring Stollberg, liksom kring nästan alla andra järn- och sulfidmalmer (Cu, Pb, Zn) i Bergslagen, utgörs av vulkaniska bildningar. De vulkaniska bergarterna och tillhörande malmer bilThe Paleoproterozoic Fe-Pb-Zn-Mn(-Ag) Stollberg deposit is situated in the Bergslagen region of south-central Sweden. 6.65 Mt of sphalerite, galena and manganiferous skarn magnetite ore occur as disseminations and semi-massive to massive ore bodies hosted by volcanogenic sediments and carbonate rocks. Field relations, mineralogy and geochemistry suggest that the felsic volcanic rocks at Stoll- be
