An Interactive Tablecloth for Facilitating Discussion in a Culturally Diverse Group

Group discussions are a useful tool in a number of environments: from working towards a common goal in a business setting, to gathering feedback on an exhibit in a museum for example. One issue in such sessions is that some group members can talk more loudly and confidently than others, making some group members change their mind or keep quiet, this can result in interesting differences of opinion being lost. In this paper we present a tool for facilitating such group discussions. The tool is an interactive tablecloth that is controlled with tangible interfaces, and provides a method for each group member’s voice to be heard prior to discussion, thus preserving the diversity of responses. When tested after an immersive theatre performance, the tool effectively allowed each group member to answer questions individually prior to beginning group discussion. This also allowed the facilitator to effectively coordinate the discussion in an efficient manner

Social critique in scorsese's the age of innocence and madden's ethan frome: filmic adaptations of two novels by Edith Wharton

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoAnálise das obras The Age of Innocence (1920) e Ethan Frome (1911) da escritora americana Edith Wharton, e suas recentes adaptações cinematográficas pelos diretores Martin Scorsese e John Madden, respectivamente. O estudo discute a transposição do tema de crítica social dos romances para os filmes. O ?mise-en-scene? e a narração em ?voice-over?, de ambas as adaptações são analisados considerando sua importância para a elaboração da temática dos romances. A análise indica que enquanto a adaptação de Scorsese transpõe para a tela a textura social de sua fonte através de um ?mise-en-scene? detalhado e de uma enfática narradora em ?voice-over?, a adaptação de Madden insere um tom religioso e moralístico ao filme quando diverge do esquema narratológico de Wharton

In the dark – designing navigation for a haptic theatre experience

We describe the ongoing work of a collaborative theatre project, in which blind and sighted members of an interdisciplinary team are working on the creation of an immersive and accessible theatre experience. The theatre experience is set in pitch dark, and uses audio and haptic ubiquitous technologies to guide both blind and sighted members of the audience. During two sessions which explored the use of enactive navigation in the dark space, participants were able to locate areas of interest within the dark, using enactive explorative navigation, and some participants described this as a ‘dense’ experience

Orbital polarons versus itinerant e_g electrons in doped manganites

We study an effective one-dimensional (1D) orbital t-J model derived for strongly correlated e_g electrons in doped manganites. The ferromagnetic spin order at half filling is supported by orbital superexchange prop. to J which stabilizes orbital order with alternating x^2-y^2 and 3z^2-r^2 orbitals. In a doped system it competes with the kinetic energy prop. to t. When a single hole is doped to a half-filled chain, its motion is hindered and a localized orbital polaron is formed. An increasing doping generates either separated polarons or phase separation into hole-rich and hole-poor regions, and eventually polarizes the orbitals and gives a it metallic phase with occupied 3z^2-r^2 orbitals. This crossover, investigated by exact diagonalization at zero temperature, is demonstrated both by the behavior of correlation functions and by spectral properties, showing that the orbital chain with Ising superexchange is more classical and thus radically different from the 1D spin t-J model. At finite temperature we derive and investigate an effective 1D orbital model using a combination of exact diagonalization with classical Monte-Carlo for spin correlations. A competition between the antiferromagnetic and ferromagnetic spin order was established at half filling, and localized polarons were found for antiferromagnetic interactions at low hole doping. Finally, we clarify that the Jahn-Teller alternating potential stabilizes the orbital order with staggered orbitals, inducing the ferromagnetic spin order and enhancing the localized features in the excitation spectra. Implications of these findings for colossal magnetoresistance manganites are discussed.Comment: 19 pages, 20 figure

Implementing a New Electronic Health Record System in a University Hospital : The Effect on Reported Medication Errors

Closed-loop electronic medication management systems (EMMS) have been seen as a potential technology to prevent medication errors (MEs), although the research on them is still limited. The aim of this paper was to describe the changes in reported MEs in Helsinki University Hospital (HUS) during and after implementing an EPIC-based electronic health record system (APOTTI), with the first features of a closed-loop EMMS. MEs reported from January 2018 to May 2021 were analysed to identify changes in ME trends with quantitative analysis. Severe MEs were also analysed via qualitative content analysis. A total of 30% (n = 23,492/79,272) of all reported patient safety incidents were MEs. Implementation phases momentarily increased the ME reporting, which soon decreased back to the earlier level. Administration and dispensing errors decreased, but medication reconciliation, ordering, and prescribing errors increased. The ranking of the TOP 10 medications related to MEs remained relatively stable. There were 92 severe MEs related to APOTTI (43% of all severe MEs). The majority of these (55%, n = 53) were related to use and user skills, 24% (n = 23) were technical failures and flaws, and 21% (n = 21) were related to both. Using EMMS required major changes in the medication process and new technical systems and technology. Our medication-use process is approaching a closed-loop system, which seems to provide safer dispensing and administration of medications. However, medication reconciliation, ordering, and prescribing still need to be improved.Peer reviewe

First validation of the Haptic Sandwich: a shape changing handheld haptic navigation aid

This paper presents the Haptic Sandwich, a handheld robotic device that designed to provide pedestrian navigation instructions through a novel shape changing modality. The device resembles a cube with an articulated upper half that is able to rotate and translate (extend) relative to the bottom half, which is grounded in the user’s hand when the device is held. The poses assumed by the device simultaneously correspond to heading and proximity to a navigational target. The Haptic Sandwich provides an alternative to screen and/or audio based pedestrian navigation technologies for both visually impaired and sighted users. Unlike other robotic or haptic navigational solutions, the haptic sandwich is discrete in terms of form and sensory stimulus. Due to the novel and unexplored nature of shape changing interfaces, two user studies were undertaken to validate the concept and device. In the first experiment, stationary participants attempted to identify poses assumed by the device, which was hidden from view. In the second experiment, participants attempted to locate a sequence of invisible navigational targets while walking with the device. Of 1080 pose presentations to 10 individuals in experiment one, 80% were correctly identified and 17.5% had the minimal possible error. Multi-DOF errors accounted for only 1.1% of all answers. The role of simultaneous or independent actuator motion on final shape perception was tested with no significant performance difference. The rotation and extension DOF had significantly different perception accuracy. In the second experiment, participants demonstrated good navigational ability with the device after minimal training and were able to locate all presented targets. Mean motion efficiency of the participants was between 32%-56%. Participants made use of both DOF

Girls for girls programme, Kenya

Friends of Londiani (FOL) in partnership with Girl Guide and Girl Scout Leaders from around the world are working with schools and communities in the Districts of Londiani and Kipkelion to enable girls to remain in school. Girls often miss days of school due to lack of access to affordable sanitary products, and lack of sanitation facilities in schools. The community has identified that its lack of ability to address this simple issue leads to girls leaving school at an early age (at a disproportionate rate than boys) and leaves girls without skills necessary to participate in money-earning activities later in life, and unable to make informed decisions about their future. The Girls for Girls Programme includes a menstrual health hygiene education programme

Control and Being Controlled: Exploring the use of Technology in an Immersive Theatre Performance

Immersive theatre is a growing trend within theatre entertainment: audience members can now wander around performances and choose how the story unfolds in front of them. Technology can be used to create novel, multi-modal experiences for audiences in these performances; but when the rules of such an experience are ill-defined, how do users react to this technology? We present an evaluation of 25 performances of an immersive, in the dark performance. Issues of control can arise in situations where technology becomes an important part of such a performance. Participants take and relinquish control in three key areas: navigation, exploration and attention during the performance, and this affects their perception of both technology and the piece itself. We discuss how technology can play a positive role in immersive theatre and other cultural settings, yet its use must be carefully choreographed to ensure the audience experience matches the intended goal
