- Table 3 in the original paper reports inaccurate values of Q0exp;YSC and Q0obs(and hence of the related quantities Qexp;tot, Qexptot=Qobs, and fesc). The error in Q0exp;YSC results from a mistake in the sampling of the cluster probability distribution functions (PDFs), whereas Q0obswas mistakenly computed from non-dereddened values of L(Hα). In Table 1 we provide a revised version of the original Table 3, and in Figs. 1 and 2 we show revised versions of the original Figs. 10 and 11. The revised values do not change any of the conclusions stated in the original paper. In the following we provide revised text for the affected sections. (Figure Presented).

CLusters in the UV as EngineS (CLUES). I. Survey Presentation and FUV Spectral Analysis of the Stellar Light

- The CLusters in the Uv as EngineS (CLUES) survey is a Cosmic Origins Spectrograph (COS) campaign aimed at acquiring the 1130–1770 Å rest-frame spectroscopy of very young (<20 Myr) and massive (>104 M⊙) star clusters in galaxies that are part of the Hubble treasury program Legacy ExtraGalactic UV Survey. In this first paper of a series, we describe the CLUES sample consisting of 20 young star clusters and report their physical properties as derived by both multiwavelength photometry and far-UV (FUV) spectroscopy with Hubble Space Telescope. Thanks to the synergy of the two different data sets, we build a coherent picture of the diverse stellar populations found in each region (with sizes of 40–160 pc). We associate the FUV-brightest stellar population to the central targeted star cluster and the other modeled population to the diffuse stars that are included in the COS aperture. We observe better agreement between photometric and spectroscopic ages for star clusters younger than 5 Myr. For clusters older than 5 Myr, photometry and spectroscopy measurements deviate, with the latter producing older ages, due to the degeneracy of photometric models. FUV spectroscopy enables us to better constrain the stellar metallicities, a parameter that optical colors are insensitive to. Finally, the derived E(B − V) are quite similar, with a tendency for FUV spectroscopy to favor solutions with higher extinctions. The recovered masses are in agreement within a factor of 2 for all of the clusters.

Adopting Mobility-as-a-Service: An empirical analysis of end-users' experiences
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Despite widespread interest, empirical research on how end-users perceive and use Mobility-as-a-Service (MaaS) is scarce. To address this knowledge gap, this paper analyzes the end-user process of adopting a MaaS service entitled EC2B, which was launched in Gothenburg (Sweden) in the spring of 2019. The contribution to the MaaS literature is three-fold. Firstly, the paper provides insight into potential user segments by describing the characteristics and motives of the studied pool of adopters. Secondly, it improves the understanding of the potential effects of MaaS by outlining how the EC2B service was used and how it influenced travel behavior. Thirdly, the paper informs strategies for facilitating MaaS adoption by outlining what types of drivers and barriers the end-users faced during different stages of the adoption process. The reported findings underscore previous assertions that MaaS is much more than just an app and a subscription plan and highlight the mutually reinforcing relationship between the introduction of MaaS and the implementation of policies aimed at reducing car use.

Omdefinierad roll för kollektivtrafiken : En kunskapsöversikt
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Hur kan kollektivtrafiken omdefiniera sin roll för att bli bättre på att dra nytta av möjligheterna med andra hållbara trafikslag, kombinerat resande och integrerade mobilitetstjänster? Den frågan ställer K2 Nationellt kunskapscentrum för kollektivtrafik till Rådslaget för hållbar omstart – ett initiativ för förnyelse av kollektivtrafik som uppkommit i kölvattnet av coronapandemin. I syfte att skapa en gemensam utgångspunkt för den diskussionen ämnar den här texten att i korthet ge en överblick över den samhällsorganiserade kollektivtrafiken och dess roll i Sverige idag samt hur rollens utveckling för närvarande diskuteras. Sammanställningen gör inga anspråk på att vara allomfattande och representerar inte nödvändigtvis vare sig K2s eller RISE position i frågan.
