A Case Study on Participatory Approach to Support Shift to Experience Design of Work Tools in B2B Context

To support the shift from technology-driven to experience-driven design in a company developing work tools (materials handling equipment), we developed and applied a participatory approach to increase awareness and buy-in of experience design and related methods at the company. We 1) present user experience (UX) design guidelines developed for both designers and managers based on the participatory process, 2) report evaluation of the guidelines with designers, developers, and selected internal and external stakeholders, and 3) present a participatory approach to create personas and experience journey maps covering the product life-cycle. SWOT analysis of the guidelines revealed that guidelines need to be understandable without expert UX knowledge, managerial support is needed that was aimed to be supported by the guidelines developed for managers, and representative user participation is needed. Participants experienced positively the applied participatory approach, and the mindset change is proceeding in the case company

A volumetric Penrose inequality for conformally flat manifolds

We consider asymptotically flat Riemannian manifolds with nonnegative scalar curvature that are conformal to $\R^{n}\setminus \Omega, n\ge 3$, and so that their boundary is a minimal hypersurface. (Here, $\Omega\subset \R^{n}$ is open bounded with smooth mean-convex boundary.) We prove that the ADM mass of any such manifold is bounded below by $(V/\beta_{n})^{(n-2)/n}$, where $V$ is the Euclidean volume of $\Omega$ and $\beta_{n}$ is the volume of the Euclidean unit $n$-ball. This gives a partial proof to a conjecture of Bray and Iga \cite{brayiga}. Surprisingly, we do not require the boundary to be outermost.Comment: 7 page

Sää- ja ilmastoriskit Suomessa - Kansallinen arvio

Tähän raporttiin on koottu ajantasainen arvio sään ja ilmaston aiheuttamista riskeistä eri toimialoille Suomessa. Arviossa otettiin huomioon sekä muuttuvan ilmaston että yhteiskunnallisen kehityksen vaikutus riskin muodostumiseen nykyhetkessä ja tulevaisuudessa. Sää- ja ilmastoriskejä pyrittiin hahmottamaan vaaratekijän (riskiä aiheuttava sääilmiö), altistumisen (riskin kohteen sijainti) ja haavoittuvuuden (riskin kohteen ominaisuudet) yhdistelmänä. Sääilmiöt aiheuttavat Suomessa riskejä jo nykyilmastossa. Muun muassa rajuilmat, helleaallot ja rankkasateet aiheuttavat taloudellisia ja terveydellisiä vaikutuksia sekä yleistä haittaa. Tulevaisuudessa riskit muuttuvat ilmastonmuutoksen muuttaessa haitallisia sääilmiöitä. Ilmastonmuutos tuo vähitellen kasvavia riskejä erityisesti ekosysteemeille ja infrastruktuurille. Muualla maailmalla tapahtuvat ilmastonmuutoksen vaikutukset voivat heijastua epäsuorasti Suomeen globaalien tavara-, energia-, raha- ja ihmisvirtojen kautta. Näiden riskien systemaattinen arviointi on vasta aloitettu. Raportin tavoitteena on tukea yhteiskunnan riskeihin varautumista ja ilmastonmuutokseen sopeutumista eri hallinnon tasoilla ja toimialoilla. Arvio perustuu pääosin kirjallisuudesta löytyviin tutkimuksiin ja selvityksiin sekä asiantuntija-arvioihin. Työ tehtiin “Sää- ja ilmastoriskien arviointi ja toimintamallit” (SIETO)- hankkeessa vuosina 2017–2018

Policy monitoring in the EU: The impact of institutions, implementation, and quality

Policy monitoring is often seen as a crucial ingredient of policy evaluation, but theoretically informed empirical analyses of real-world policy monitoring practices are still rare. This paper addresses this gap by focusing on climate policy monitoring in the European Union, which has a relatively stringent system of greenhouse gas monitoring but a much less demanding approach to monitoring policies. It explores how institutional settings, policy implementation, and the quality of information may impact the practices and politics of policy monitoring. Drawing on quantitative regression models and qualitative interviews, it demonstrates that policy monitoring has evolved over time and is itself subject to implementation pressures, but also exhibits learning effects that improve its quality. In further developing both everyday policy monitoring practices and academic understanding of them, there is a need to pay attention to their design—specifically, the impact of any overarching rules, the institutional support for implementation, and the criteria governing the quality of the information they deliver. In short, policy monitoring should be treated as a governance activity in its own right, raising many different design challenges

Stability mechanisms of a thermophilic laccase probed by molecular dynamics.

Laccases are highly stable, industrially important enzymes capable of oxidizing a large range of substrates. Causes for their stability are, as for other proteins, poorly understood. In this work, multiple-seed molecular dynamics (MD) was applied to a Trametes versicolor laccase in response to variable ionic strengths, temperatures, and glycosylation status. Near-physiological conditions provided excellent agreement with the crystal structure (average RMSD ∼0.92 Å) and residual agreement with experimental B-factors. The persistence of backbone hydrogen bonds was identified as a key descriptor of structural response to environment, whereas solvent-accessibility, radius of gyration, and fluctuations were only locally relevant. Backbone hydrogen bonds decreased systematically with temperature in all simulations (∼9 per 50 K), probing structural changes associated with enthalpy-entropy compensation. Approaching T opt (∼350 K) from 300 K, this change correlated with a beginning "unzipping" of critical β-sheets. 0 M ionic strength triggered partial denucleation of the C-terminal (known experimentally to be sensitive) at 400 K, suggesting a general salt stabilization effect. In contrast, F(-) (but not Cl(-)) specifically impaired secondary structure by formation of strong hydrogen bonds with backbone NH, providing a mechanism for experimentally observed small anion destabilization, potentially remedied by site-directed mutagenesis at critical intrusion sites. N-glycosylation was found to support structural integrity by increasing persistent backbone hydrogen bonds by ∼4 across simulations, mainly via prevention of F(-) intrusion. Hydrogen-bond loss in distinct loop regions and ends of critical β-sheets suggest potential strategies for laboratory optimization of these industrially important enzymes

Five Nuclear Loci Resolve the Polyploid History of Switchgrass (Panicum virgatum L.) and Relatives

Polyploidy poses challenges for phylogenetic reconstruction because of the need to identify and distinguish between homoeologous loci. This can be addressed by use of low copy nuclear markers. Panicum s.s. is a genus of about 100 species in the grass tribe Paniceae, subfamily Panicoideae, and is divided into five sections. Many of the species are known to be polyploids. The most well-known of the Panicum polyploids are switchgrass (Panicum virgatum) and common or Proso millet (P. miliaceum). Switchgrass is in section Virgata, along with P. tricholaenoides, P. amarum, and P. amarulum, whereas P. miliaceum is in sect. Panicum. We have generated sequence data from five low copy nuclear loci and two chloroplast loci and have clarified the origin of P. virgatum. We find that all members of sects. Virgata and Urvilleana are the result of diversification after a single allopolyploidy event. The closest diploid relatives of switchgrass are in sect. Rudgeana, native to Central and South America. Within sections Virgata and Urvilleana, P. tricholaenoides is sister to the remaining species. Panicum racemosum and P. urvilleanum form a clade, which may be sister to P. chloroleucum. Panicum amarum, P. amarulum, and the lowland and upland ecotypes of P. virgatum together form a clade, within which relationships are complex. Hexaploid and octoploid plants are likely allopolyploids, with P. amarum and P. amarulum sharing genomes with P. virgatum. Octoploid P. virgatum plants are formed via hybridization between disparate tetraploids. We show that polyploidy precedes diversification in a complex set of polyploids; our data thus suggest that polyploidy could provide the raw material for diversification. In addition, we show two rounds of allopolyploidization in the ancestry of switchgrass, and identify additional species that may be part of its broader gene pool. This may be relevant for development of the crop for biofuels
