This study explores the practical applicability of the Communication Value Circle (Zerfass & Viertmann, 2017), a recent theoretical framework that describes value creation through communication in 12 dimensions drawn from four generic corporate goals. The research objective is to evaluate whether key claims from the CVC hold up in practice. Hence, a multistage research design comprising two ro
Despite a recent interest among geographers and planners in experiments in and on the city, urban experimentation has yet to be examined critically. This thesis takes on the challenge by conceptualizing the place experiment as hermeneutical, transformative, co-creational and geographically bounded, and further by examining the strategic use of place experiments in municipal urban planning. The the
Syfte & mål: Studiens syfte är att undersöka vilka utmaningar byggsektorn står inför nu när klimatdeklaration blivit lag. Hur stor omställning har klimatdeklarationen orsakat byggsektorn och vad krävs av de arbetsroller som är involverade i framställningen av en klimatdeklaration. Vilka incitament har byggherren vid dagsläget att bygga klimatsmart utan gränsvärden från lagkravet. ProblemstäAim & goal: The purpose of the study is to investigate what challenges the construction sector is facing now that the climate declaration has become law. How much change has the climate declaration caused the construction sector and what is required of the work roles involved in the production of a climate declaration. What incentives does the developer currently have to build climate-smart wi
The 'trade-off' hypothesis for virulence evolution assumes that between-host transmission rate is a positive and saturating function of pathogen exploitation and virulence, but there are as yet few tests of this assumption, in particular for vector-borne pathogens. Here, I show that the infectivity (probability of transmission) of the tick-borne bacterium Borrelia afzelii from two of its natural r
Denna uppsats syftar till att, ur ett kritiskt legalitets- och rättssäkerhetsperspektiv, undersöka förarbetens roll vid lagtolkning på straffrättens område, särskilt vad gäller straffmätning. År 2014 ändrades straffet för mord. I lagtextens förarbeten angavs ett tydligt syfte med ändringen: straffet för mord skulle skärpas och livstidsstraff skulle bli ”normalstraffet” för mord i det att det skuThis essay aims to examine the use of legal preparatory works when interpreting criminal law in Sweden. The examination is conducted from a critical perspective with a focus on the principle of legality and the requirement of legal certainty. In 2014 the provision regulating the penalty for murder was altered. The legal preparatory works clearly expressed the purpose of the amendment: the penalt
The research area of this essay is the people's perception of the post modern/late modern society's increasing individualization and increasing number of choices. The main theoretical points are Giddens and Bauman's theories about humans in the post modern/late modern society. Giddens describes reflexivity as a way to consider your own role and your responsibility to society. Bauman is
A control system for pneumatic variable valve actuation has been designed, implemented and tested in a single cylinder test engine with valve actuators provided by Cargine Engineering AB. The design goal for the valve control system was to achieve valve lifts between 2 and 12 mm over an engine speed interval of 300 to 2500 rpm. The control system was developed using LabView and implemented on the
The ATP- and UTP-sensitive P2Y2 receptor which mediates both contractile and mitogenic effects has recently been shown to be upregulated in the synthetic phenotype of the vascular smooth muscle cell (VSMC). Using a competitive RT-PCR we demonstrate that the P2Y2 receptor mRNA is increased by fetal calf serum and other growth factors in a MAPKK-dependent way. This was confirmed at the functional le
A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm2. A fundamental oscillation frequency
Natural lifetimes of some highly excited levels in the Pb-I spectrum have been measured by the zero field level crossing (Hanle) method. The levels were reached by optical excitation from the metastable 6p2 3P2 and 6p2 3P1 states, were a considerable population had been created by means of adc discharge in a Pb atomic beam. An atomic beam source producing atoms in metastable states is described. F
This article focuses on videography as a method for conducting research, as a means of communicating findings about tags and tagging to the public, and an opportunity to re-evaluate previously-collected empirical material.Based on ongoing explorative videographic research, the author discusses how the video medium can be used to go beyond the mere visual representation of tags as singular expressi
The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). The automotive industry is continuously striving to find new solutions to decrease fuel consumpt
This study uses a discontinuity in the Swedish tertiary eligibility requirement to estimate the probability of enrolling in tertiary education, and the payoff thereof. Regression discontinuity results, show that achieving tertiary eligibility in upper-secondary education, increases the probability of enrolling in tertiary education by around 10–15 and 7 percentage points for students who enrolled
Spatially coupled turbo-like codes (SC-TCs) have been shown to have excellent decoding thresholds due to the threshold saturation effect. Furthermore, even for moderate block lengths, the simulation results demonstrate a very good bit error rate performance in the waterfall region. In this paper, we discuss the effect of spatial coupling on the performance of TCs in the finite block-length regime.
Objective. To compare the effect of intraarticular injections of hyaluronan and placebo (vehicle, saline) in patients with knee pain on exertion and with joint cartilage abnormalities. Methods. Fifty-two patients with arthroscopically verified deep cartilage fissures and villus-like flakes in the symptomatic knee were randomly assigned to receive intraarticular injections of 2.5 ml of either hyalu
