Tidskriftsartikel (refereegranskat)abstract
- Based on a literature review, this article shows that current mediatization scholarship is characterized by what Pike (1967) refers to as etic accounts. These accounts forward theoretical categories on media-related social change to conclude that our age is characterized by deepened and expanded media reliance. However, such theoretical extrapolation takes place not from, but at the expense of, people’s lived experiences, that is, emic accounts of mediatization in everyday life. This article is an attempt to insert the etic/emic distinction to mediatization research in order to develop more reflexive and composite accounts. Drawing on examples from a representative survey and qualitative interviews conducted over twenty years, the article problematizes eticoriented conceptions of mediatization. Emic analyses expose how perceptions of media reliance shift over time and thus underscore the need to develop research strategies that simultaneously consider the objective structures of the social (mediatized) world and subjective meaning-making structures.

- In 1994, sociologist of religion José Casanova wrote in the introduction to his influential book Public Religions in the Modern World that a paradigm shift had occurred in his field. His colleagues had abandoned an earlier paradigm “with the same uncritical haste with which they previously embraced it.” 1 What he had in mind was the theory of secularisation: that is, the notion that with modernisation, religion would disappear from the public sphere, if not altogether. The theory was now, he claimed, something of a myth in the eyes of many of his colleagues, rather than the accepted knowledge it used to be.

Chapter 15: Circular economy and sustainable consumption: Suggestions for ethical marketing
- 2020
-
Ingår i: The SAGE Handbook of Marketing Ethics. - 9781529709292
-
Bokkapitel (refereegranskat)abstract
- Currently there is an ongoing push towards a circular economy. Governments, the EU, green NGOs, think-tanks, companies and their industry organizations are all advocating more circular solutions meaning that the current linear take-make-use-lose model of consumption should be replaced with a reuse-repair-recycle circular model. The circular economy is being heralded as one of the main, if not the only, solution to the current pressing sustainability problems such as climate change and biodiversity loss. Companies are struggling to develop business models that are more in line with this circular thinking, closely related to the so-called sharing economy, where sharing of product take priority over ownership. Car sharing, tool libraries, and repair shops are some examples that are starting to attract consumers, although progress hitherto has been slow. In order to attract consumers, words such as refurbished, zero-waste, recycled, and recyclable are being used by marketers. At the surface it might be easy to get the impression that the circular economy is already here and that consumers can go on consuming as before as long as the products are part of the circular system. Might it even be so that an increasing focus on the circular economy could detract attention from the necessary reduction of consumption and material throughput? The purpose of this chapter is to critically examine the problems and possibilities of the circular economy and discuss how it is related to (un)ethical marketing and what is necessary if the circular economy is to contribute to solving the pressing sustainability problems. This is done by discussing how the circular economy can be promoted together with consumption reduction, the necessity of certain policies and regulations, and the importance of handling consumer lock-in and potential rebound effects in making the circular economy not only technically achievable but also more ethical.

Image-based semi-multiscale finite element analysis using elastic subdomain homogenization

Tidskriftsartikel (refereegranskat)abstract
- In this paper we present a semi-multiscale methodology, where a micrograph is split into multiple independent numerical model subdomains. The purpose of this approach is to enable a controlled reduction in model fidelity at the microscale, while providing more detailed material data for component level- or more advanced finite element models. The effective anisotropic elastic properties of each subdomain are computed using periodic boundary conditions, and are subsequently mapped back to a reduced mesh of the original micrograph. Alternatively, effective isotropic properties are generated using a semi-analytical method, based on averaged Hashin–Shtrikman bounds with fractions determined via pixel summation. The chosen discretization strategy (pixelwise or partially smoothed) is shown to introduce an uncertainty in effective properties lower than 2% for the edge-case of a finite plate containing a circular hole. The methodology is applied to a aluminium alloy micrograph. It is shown that the number of elements in the aluminium model can be reduced by 99.89 % while not deviating from the reference model effective material properties by more than 0.65 % , while also retaining some of the characteristics of the stress-field. The computational time of the semi-analytical method is shown to be several orders of magnitude lower than the numerical one. © 2021, The Author(s).

Marknadsföring och varumärken i kollektivtrafiken : Rapport från en kvalitativ studie
- 2020. - 9
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Kollektivtrafiken är en viktig del i omställningen till ett mer miljömässigt hållbart resande. De alltmer marknads- och kundorienterade regionala kollektivtrafikmyndigheterna marknadsför sig idag med en mängd budskap i en växande flora av kanaler som direktutskick, hemsidor och appar. Denna kommunikation och marknadsföring är en del av den påverkan som resenären har att förhålla sig till i ett allt högre mediebrus. Forskning och lärdomar från privata företag visar att en genomtänkt marknadsföringsstrategi och tydliga varumärkesvärderingar kan bidra till att lyfta attraktivitet och försäljning. Hur ser detta ut inom kollektivtrafikbranschen generellt och hur arbetar de regionala kollektivtrafikmyndigheterna med dessa frågor? Denna rapport presenterar och diskuterar resultatet från en studie kring hur de regionala kollektivtrafikmyndigheterna i Sverige ser på och arbetar med marknadsföring, marknadsorientering och varumärken. Förutom en del rapporter och litteratur i ämnet, baseras rapporten på ett tiotal intervjuer med personer med ansvar för kommunikation, marknadsföring och varumärken i de tre storstadsregionerna Stockholm, Malmö och Göteborg. Resultaten visar att de tre myndigheterna kommit olika långt i sitt arbete med marknadsorientering, marknadsföring och varumärken, och att det ofta saknas en samsyn inom respektive myndighet dels om hur viktigt marknadsförings- och kommunikationsarbetet är, men också om vad som ingår, eller bör ingå i detta arbete. Det är tydligt att aktörerna är i ett uppstartsskede av att tänka och agera i termer av marknadsföringsstrategier och varumärkeshantering och det gör att deras insatser kan upplevas som spretiga och att deras position på marknaden inte är tydlig för viktiga externa intressenter såsom resenärer och företag. Samtidigt är alla tre myndigheterna väl medvetna om vikten av kommunikation som en del i att ta andelar från individuellt bilresande. En stor del av den kommunikation som diskuteras bland myndigheterna rör funktionella aspekter som tidtabellförändringar, störningar och betalningslösningar och denna information samordnas sällan med det generella marknadsförings- och varumärkesarbetet. Kollektivtrafikmyndigheterna har också svårt att tydligt definiera de grundläggande värden som styr deras organisationer och det uppstår därför en skillnad mellan intern och extern syn på deras varumärken som i sin tur leder till ambivalens och en otydlig position på marknaden. Slutsatserna och rekommendationerna kretsar kring att om kollektivtrafikmyndigheterna önskar uppnå ökad kännedom, synlighet, nöjda resenärer och ett ökat anseende både bland resenärer och andra samhällsaktörer bör de arbeta mer strategiskt och långsiktigt med sin kommunikation, utgå från några tydligt förankrade gemensamma värdeord som kan föra dem framåt, och använda dessa för att bygga en tydlig position på marknaden. På sikt skulle detta också öka deras möjligheter att möta andra utmaningar som teknikomställning, förändrade resmönster, ökade krav på tillförlitlighet, säkerhet och prisvärdhet.

Multiscale Constitutive Modeling of Heterogeneous Engineering Materials
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This work deals with different methods used to determine heterogeneous constitutive model parameters for macro-scale finite element models, based on microstructural variations, caused by the manufacturing process. These methods could be applied to decrease modeling errors associated with the material behavior, improving the predictive capabilities of structural analyses in simulation-driven industrial product development. By providing engineers with more sophisticated tools and methods which lets them consider the complex relationships between the manufacturing process, the resulting microstructure and the final properties, manufactured components have the potential to be further optimized with respect to both weight and performance, reducing their cost and environmental impact.An empirical approach for cast components is presented in Papers I & II, where material testing is used as a basis for constitutive model parameter extraction via optimization. Linear models were created for both thermo-mechanical and thermo-physical material properties, by characterizing specimens extracted from different regions in a lamellar graphite cast iron cylinder head. These models were used to generate heterogeneous constitutive model parameters for the cylinder head, based on the solidification time as predicted by casting process simulations. The influence of several commonly made casting-specific engineering simplifications were investigated, and it was shown that non-trivial errors of a potentially large magnitude are introduced by not considering e.g. the compressive behavior of the material, residual stresses from the casting process, the temperature dependency of the material, or the process-induced heterogeneity.Paper III describes a statistical homogenization-based method, for modeling of anisotropic fiber reinforced materials. A non-linear anisotropic constitutive model was developed and implemented in commercial finite element codes, which is able to consider heterogeneous fiber orientations using only one material definition. The anisotropic elastic constitutive tensor is determined from fiber-matrix homogenization, and orientation averaging using second- and fourth order fiber orientation tensors provided by injection molding simulations. The plastic constitutive parameters are determined by optimization against experimental tensile tests using specimens with different fiber orientations. The method was demonstrated using a injection molded 50 wt.% short glass fiber reinforced plastic.A pixel/voxel-based method is presented in Papers IV (2D) & V (3D), for simple and efficient generation of reduced numerical microstructure models using imaging data as input. The input micrograph or image stack is split into subdomains, which are evaluated individually using numerical or semi-analytical homogenization. The constitutive tensor of each subdomain is mapped to a new, reduced numerical model. The purpose of this approach was to support component level analyses, by representing process-induced microstructural imperfections like e.g. porosity on the macro-scale, in a computationally efficient way. The geometrical description of the microstructure can be retrieved from experimental imaging methods like Scanning Electron Microscopy (SEM) or X-ray based Computed Tomography (CT). Alternatively, it can be approximated from phase field or manufacturing process simulations. The method was demonstrated by reducing a 2D aluminium micrograph by 99.89%, with material property errors of less than 0.5% in Paper IV. Also, in paper V by reducing a complex high-resolution 3D aluminum shrinkage porosity by 99.2%, with a material property error of approximately 1%. The method significantly reduces the complexity of building finite element models of complex microstructures, where the pre-processing step is replaced by image segmentation.

- In this chapter we take a look at some, primarily, environmental sustainability issues in Sweden. Sweden is in many aspects a rich country with high social and economic welfare and it usually comes out as a country that has handled environmental challenges well. However, from a consumption perspective, Swedish consumers are among the world leaders when it comes to metrics such as ecological footprint and carbon dioxide emissions per capita. By using two paradigmatic views, the Dominant Social Paradigm (DSP) and the New Ecological Paradigm (NEP) we analyze sustainability in Sweden with a particular focus on energy use. We look at sustainability in the three broad areas of policies, corporate activities and consumption and in these areas we delve deeper into environmental sustainability issues concerning recycling and waste, energy efficiency, circular business models, sustainable consumer behaviors in relation to cars and transport, and responsible investments. We end the chapter by discussing implications for the future and the analytical framework and by developing a middle ground which we call ambiguous wavering.
