Digital kommunikation medför nya möjligheter för privatpersoner och organisationer att kommunicera. Idag kan de i realtid utbyta information och på så sätt komma närmre sina intressenter. Det är dock oklart hur många som känner till vilken effekt deras digitala kommunikation har. Den här studien undersöker hur kommunala organisationer använder, mäter och utvärderar resultaten av sin digitala kommuDigital communication brings new opportunities for communication between organizations and their stakeholders. Digital channels enable exchange of information in real time and organizations recognize the benefits of having close connections to interested parties. It is however unclear how many organizations that know the effect of their digital communication efforts. This study examines how munici

Under seeing limited conditions very high resolution spectroscopy becomes very difficult for extremely large telescopes (ELTs). Using adaptive optics (AO) the stellar image size decreases proportional with the telescope diameter. This makes the spectrograph optics and hence its resolution independent of the telescope diameter. However AO for use with ELTs at visible wavelengths require deformable

Spin-echo modulation small-angle neutron scattering (SEMSANS) is based on the detection of spatial beam modulation, which is induced by triangular spin echo precession regions and subsequent spin analyses. In order to detect such signal and exploit it for small angle scattering investigations neutron detection with sub-millimeter spatial resolution is required. Here an approach is reported where i

The goal of this study is to investigate the applicability of asymmetrical flow field-flow fractionation (AsFlFFF)–multi angle laser light scattering (MALLS), and to develop a method for analysis of cationic potato amylopectin (CPAP) having ultrahigh molecular mass (UHMr). Use of the aqueous carrier having low salt content (3 mM NaN3) resulted in a distortion in AsFlFFF fractograms of CPAP with a

Introduction A study was undertaken to test the hypothesis that musculoskeletal pain is associated with low vitamin D levels but the relationship is explained by physical inactivity and/or other putative confounding factors. Methods Men aged 40-79 years completed a postal questionnaire including a pain assessment and attended a clinical assessment (lifestyle questionnaire, physical performance tes

Unicompartmental knee arthroplasty (UKA) is known to have a higher risk of revision than tricompartmental arthroplasty (TKA), while UKA implants are generally less expensive than TKA implants. We estimated the costs of implants and hospital stay of both procedures and related the cost difference at primary operation to the difference in number of revisions to be expected. We compared 15,437 primar

Climate change poses an immediate challenge to every actor in society. In this rapidly changing context, organizations are faced with a need to make structural changes to their business strategy and operations as current business models are challenged. Communication is a vital aspect and determinant of organizational change. The purpose of this study has been to examine how an organization communi

20191022 Inresande forskningspraktikanter (grund- eller masterstudenter) Den internationella kommittén vid Institutionen för psykologi har beslutat om riktlinjer för att skapa bra förutsättningar för ett ömsesidigt givande forskningssamarbete mellan inkommande forskningspraktikanter samt ansvariga forskare. Då du som forskare blir kontaktad av internationella studenter som önskar delta i ett forsk

A new method for noise reduction using spatiotemporal smoothing is presented in this paper. The method is developed especially for reducing the noise that arises when acquiring video sequences with a camera under very dim light conditions. The work is inspired by research on the vision of nocturnal animals and the adaptive spatial and temporal summation that is prevalent in the visual systems of t
