Corporate reputation past and future: a review and integration of existing literature and a framework for future research
The concept of corporate reputation is steadily growing in interest among management researchers and practitioners. In this article, we trace key milestones in the development of reputation literature over the past six decades to suggest important research gaps as well as to provide contextual background for a subsequent integration of approaches and future outlook. In particular we explore the need for better categorised outcomes; a wider range of causes; and a deeper understanding of contingencies and moderators to advance the field beyond its current state while also taking account of developments in the macro business environment. The article concludes by presenting a novel reputation framework that integrates insights from reputation theory and studies, outlines gaps in knowledge and offers directions for future research

Characterization of soft amyloid cores in human prion-like proteins
Prion-like behaviour is attracting much attention due to the growing evidences that amyloid-like self-assembly may reach beyond neurodegeneration and be a conserved functional mechanism. The best characterized functional prions correspond to a subset of yeast proteins involved in translation or transcription. Their conformational promiscuity is encoded in Prion Forming Domains (PFDs), usually long and intrinsically disordered protein segments of low complexity. The compositional bias of these regions seems to be important for the transition between soluble and amyloid-like states. We have proposed that the presence of cryptic soft amyloid cores embedded in yeast PFDs can also be important for their assembly and demonstrated their existence and self-propagating abilities. Here, we used an orthogonal approach in the search of human domains that share yeast PFDs compositional bias and exhibit a predicted nucleating core, identifying 535 prion-like candidates. We selected seven proteins involved in transcriptional or translational regulation and associated to disease to characterize the properties of their amyloid cores. All of them self-assemble spontaneously into amyloid-like structures able to propagate their polymeric state. This provides support for the presence of short sequences able to trigger conformational conversion in prion-like human proteins, potentially regulating their functionality.This work was funded supported by the Spanish Ministry of Economy and Competitiveness [BIO2016-783-78310-R to S.V] and by ICREA [ICREA-Academia 2015 to S.V.
