- A proper theoretical description of the electronic structure of the 3d orbitals in the metal centers of functional metalorganics is a challenging problem. We apply density functional theory and an exact diagonalization method in a many-body approach to study the ground-state electronic configuration of an iron porphyrin (FeP) molecule. Our study reveals that the consideration of multiple Slater determinants is important, and FeP is a potential candidate for realizing a spin crossover due to a subtle balance of crystal-field effects, on-site Coulomb repulsion, and hybridization between the Fe-d orbitals and ligand N-p states. The mechanism of switching between two close-lying electronic configurations of Fe-d orbitals is shown. We discuss the generality of the suggested approach and the possibility to properly describe the electronic structure and related low-energy physics of the whole class of correlated metal-centered organometallic molecules.

Cell-to-cell heterogeneity emerges as consequence of metabolic cooperation in a synthetic yeast community

- Cells that grow together respond heterogeneously to stress even when they are genetically similar. Metabolism, a key determinant of cellular stress tolerance, may be one source of this phenotypic heterogeneity, however, this relationship is largely unclear. We used self-establishing metabolically cooperating (SeMeCo) yeast communities, in which metabolic cooperation can be followed on the basis of genotype, as a model to dissect the role of metabolic cooperation in single-cell heterogeneity. Cells within SeMeCo communities showed to be highly heterogeneous in their stress tolerance, while the survival of each cell under heat or oxidative stress, was strongly determined by its metabolic specialization. This heterogeneity emerged for all metabolite exchange interactions studied (histidine, leucine, uracil, and methionine) as well as oxidant (H2O2, diamide) and heat stress treatments. In contrast, the SeMeCo community collectively showed to be similarly tolerant to stress as wild-type populations. Moreover, stress heterogeneity did not establish as sole consequence of metabolic genotype (auxotrophic background) of the single cell, but was observed only for cells that cooperated according to their metabolic capacity. We therefore conclude that phenotypic heterogeneity and cell to cell differences in stress tolerance are emergent properties when cells cooperate in metabolism.

Paradox and market renewal Knockoffs and counterfeits as doppelganger brand images of luxury
- 2018

- Purpose - The purpose of this paper is to continue the emerging stream of literature that has found knockoffs and counterfeits to be unobtrusive or even beneficial to luxury companies by analyzing how they produce paradoxes of meaning and contribute to the renewal of luxury markets. This is done by exploring them as doppelganger brand images that reappropriate brand imagery for their own purposes. Design/methodology/approach - This is a conceptual paper that focuses on the role of knockoffs and counterfeits in the renewal of luxury markets. Findings - The findings highlight how knockoffs and counterfeits can contribute to the emergence and cyclical diffusion of luxury. As luxury offerings are introduced to the market, knockoffs and counterfeits accelerate the snob effect, aid in anchoring trends and contribute to induced obsolescence. During diffusion, knockoffs and counterfeits can strengthen aspiration, bandwagon and herding effects. In doing so, knockoffs and counterfeits create a paradox as they simultaneously legitimize the idea of the authenticity of genuine offerings through their presence in the market and create cyclical demand for novel offerings by undermining the authenticity claims of existing luxury offerings. Thus, knockoffs and counterfeits can be understood as a paradox of luxury markets that contributes to the market cyclicality not despite but because of this paradoxical interplay. Originality/value - While research on knockoffs and counterfeiting is plentiful in the field of marketing, this is among the few studies that analyze how these offerings contribute to luxury markets and their renewal.

Reimagining society through retail practice
- 2016

In: Journal of Retailing. - : Elsevier BV. - 0022-4359 .- 1873-3271. ; 92:4, s. 411-425

Journal article (peer-reviewed)abstract
- Marketing scholars with sociological and anthropological leanings have made great strides in uncovering strategic and theoretical implicationsof consumer collectives and consumption-driven market phenomena. It has not been very common that their perspectives have been brought to bearon retailing practice or theory. This ethnographic study examines a highly successful, globalizing, consumer-driven pop-up retail festival for itspotential lessons about social movements. It reveals new insights into logics and potentialities for retailing as a field of affordances for reimaginingsociety and social practices. It points especially to how eruptions of ‘carnivalesque mood’ unite everyday citizens to imagine change in a highlyregulated social context and how they utilize the practice of retailing collectively to actualize societal change.
