Value Co-creation for Smart Villages: The Institutionalization of Regional Service Ecosystems
2020
Building a versatile portfolio of public and private digital-enabled services is vital in rural and sparsely populated regions, where traditional market mechanisms alone cannot guarantee the availability of essential services. However, contemporary services tend to build on prevalent institutions, often governed by decisions based on market mechanisms, such as economies of scale – service-by-service and village-by-village. A shift is suggested towards networks of smart villages co-creating value as regional service ecosystems. We draw from institutional theory and employ the Service-dominant logic (SDL) framework in investigating value co-creation in rural villages in Sweden. Analyzing 53 l…
Chondrichthyans from the Spanish Triassic (westernmost Tethys) with remarks on the evolution of enameloid
2020
The Triassic sediments of the Iberian Peninsula has been the focus of Geological and Paleontological studies for more than a century and the stratigraphic sequence and the invertebrate assemblages are well established for a number of different basin. However, works focused on chondrichthyans faunas were nonexistent until recently. As a consequence, it has been long time assumed that chondrichthyans were very scarce (or inexistent) in the coastal environments of the current Iberian Peninsula during Triassic times. This view changed at the beginning of the last decade, with the studies of paleontologist from the department of Geology of the University of Valencia (Dra. Márquez-Aliaga, Dr. Héc…
Vertex corrections for positive-definite spectral functions of simple metals
2016
We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…

Vetīvers Chrysopogon zizaniodes kā modeļsuga ūdenstilpju fitoremediācijas pētījumiem Latvijas apstākļos
2019
Fitoremediācija ir iedarbīga vides piesārņojuma attīrīšanas tehnoloģija. Darba mērķis bija novērtēt vetīvera Chrysopogon zizanioides izmantošanu ūdenstilpju fitoremediācijas pētījumiem Latvijas apstākļos, salīdzinot tā morfoloģiskos parametrus un uzkrātos elementus dzinumos un saknēs brīvā dabā ūdenstilpēs un siltumnīcas apstākļos augušam vetīveram. C. zizanioides uzrādīja elementu (Fe, Mn, Zn, Cu, Pb, Ni un Cr) uzkrāšanas pazīmes, bet savstarpējas sakarības starp barības šķīdumā un biomasā esošo elementu koncentrāciju nenovēroja. Plostu vetīvers uzrādīja mazāko dzinumu un sakņu sauso masu, tomēr uzkrāto elementu koncentrācija plosta variantiem vairākumā gadījumu bija lielāka. Šīs pazīmes l…
