Allt fler blir allt äldre i Sverige och äldreomsorgen står inför en stor utmaning när resurser i form av ekonomiska medel och rätt personal blir allt svårare att konkurrera om. I eHälsans tidsålder utvecklas det på många håll smarta tekniska lösningar för att effektivisera och kvalitetshöja omsorgsinsatser, något som allt fler aktörer får upp ögonen för. Denna uppsats utreder behovsbilden för att kunna skapa en ny kontaktyta mellan omsorgstagare, närstående och utförare inom äldreomsorg. Uppsatsens resultat är en del av det Vinnova-finansierade projektet BoNUS VO som undersöker förutsättningarna för en sådan kontaktyta. IKT-stödet ska underlätta delaktighet i den egna omsorgen såväl som stödja yrkesutövare i arbetsuppgifter. Data samlades in genom en observationsstudie av hemtjänstarbete, deltagande i gruppsamtal med närstående till omsorgstagare samt kvalitativa intervjuer med 13 informanter som hade erfarenhet av äldreomsorg. Resultatet av dataanalysen visar på att det i dagsläget finns problem som skulle kunna undvikas genom att underlätta kommunikation och informationsdelning mellan användargrupperna. Resultaten visar också på att det finns många diskussionspunkter vad gäller nytta, motsättningar i behov och avvägningen mellan ett översiktligt eller komplext system. Studien konstaterar att det finns utrymme för vidare forskning inom området.Sweden’s population is steadily growing older and while the demand for care of senior citizens is increasing, care givers are forced to cope with diminishing resources in terms of money and qualified staff. Many put hope in new eHealth technology, as a means of raising efficiency and quality in the every day working situation. This thesis aims to study needs regarding communication, information and interaction between care takers, dependants and caregivers in geriatric care, in order to create a foundation upon which an ICT system may be built to fulfill those needs. The results presented are part of a research project focusing on future ICT systems in healthcare. Data was collected through an observational study, group discussions with informants related to care takers, and qualitative interviews with 13 informants who have extensive experience of geriatric care. The results imply there are existing problems that may be avoided by facilitating information sharing between the aforementioned groups. The study also presents some important points of discussion regarding usefulness, clashing needs of different users, and the balance between simplicity of use and system size

Old and new results for superenergy tensors from dimensionally dependent tensor identities

It is known that some results for spinors, and in particular for superenergy spinors, are much less transparent and require a lot more effort to establish, when considered from the tensor viewpoint. In this paper we demonstrate how the use of dimensionally dependent tensor identities enables us to derive a number of 4-dimensional identities by straightforward tensor methods in a signature independent manner. In particular, we consider the quadratic identity for the Bel-Robinson tensor ${\cal T}_{abcx}{\cal T}^{abcy} = \delta_x^y {\cal T}_{abcd}{\cal T}^{abcd}/4$ and also the new conservation laws for the Chevreton tensor, both of which have been obtained by spinor means; both of these results are rederived by {\it tensor} means for 4-dimensional spaces of any signature, using dimensionally dependent identities, and also we are able to conclude that there are no {\it direct} higher dimensional analogues. In addition we demonstrate a simple way to show non-existense of such identities via counter examples; in particular we show that there is no non-trivial Bel tensor analogue of this simple Bel-Robinson tensor quadratic identity. On the other hand, as a sample of the power of generalising dimensionally dependent tensor identities from four to higher dimensions, we show that the symmetry structure, trace-free and divergence-free nature of the four dimensional Bel-Robinson tensor does have an analogue for a class of tensors in higher dimensions.Comment: 18 pages; TeX fil

Evaluative Perception: Introduction

In this Introduction we introduce the central themes of the Evaluative Perception volume. After identifying historical and recent contemporary work on this topic, we discuss some central questions under three headings: (1) Questions about the Existence and Nature of Evaluative Perception: Are there perceptual experiences of values? If so, what is their nature? Are experiences of values sui generis? Are values necessary for certain kinds of experience? (2) Questions about the Epistemology of Evaluative Perception: Can evaluative experiences ever justify evaluative judgments? Are experiences of values necessary for certain kinds of justified evaluative judgments? (3) Questions about Value Theory and Evaluative Perception: Is the existence of evaluative experience supported or undermined by particular views in value theory? Are particular views in value theory supported or undermined by the existence of value experience
