Pricing of Digital Innovations as an Entrepreneurial Process
2019
How do entrepreneurs set a price for digital innovations they develop and market? This is an important question in current information society where digitalization is making established pricing models outdated. In this study, we focus on this issue by examining what kinds of activities and resources entrepreneurs possess when pricing digital innovations. Based on five case studies, including 37 interviews with key decision makers involved in the pricing process, we found that pricing of digital innovations can be conceptualized as an entrepreneurial process in which the pricing capabilities are developed based on the resources at hand. In this view, the pricing model is adjusted through neg…

Unveiling microbial structures during raw microalgae digestion and co-digestion with primary sludge to produce biogas using semi-continuous AnMBR sys…
2020
[EN] Methane production from microalgae can be enhanced through anaerobic co-digestion with carbon-rich substrates and thus mitigate the inhibition risk associated with its low C:N ratio. Acclimated microbial communities for microalgae disruption can be used as a source of natural enzymes in bioenergy production. However, co-substrates with a certain microbial diversity such as primary sludge might shift the microbial structure. Substrates were generated in a Water Resource Recovery Facility (WRRF) and combined as follows: Scenedesmus or Chlorella digestion and microalgae co-digestion with primary sludge. The study was performed using two lab-scale Anaerobic Membrane Bioreactors (AnMBR). Du…
Erodibility prioritization of sub-watersheds using morphometric parameters analysis and its mapping: A comparison among TOPSIS, VIKOR, SAW, and CF mu…
2018
Soil erosion, every year imposes extensive damages to human beings by means of reducing soil productivity and filling reservoirs from sedimentation in Ghaemshahr Basin in Mazandaran Province, (Iran); therefore, identifying prone areas to soil erosion for preventive measures is essential in this basin. In this research, erodibility prioritization of sub-watersheds of Ghaemshahr Basin has done using morphometric parameters analysis and different multi-criteria decision making (MCDM) models such as simple additive weighing (SAW), VlseKriterijumska optimizacija I Kompromisno Resenje (VIKOR), technique for order preference by similarity to ideal solution (TOPSIS), and compound factor (CF). For t…
Polychlorinated organic compounds in the Arctic cod liver: trends and profiles
2000
Polychlorinated organic compounds (POCs) have been measured in Arctic cod liver from Vestertana Fjord for a period of 1987-1998. Significant decrease was observed for DDD (p = 0.043), alpha-HCH (p = 0.001), and gamma-HCH (lindane; p = 0.001). Contents of DDE, 2,3,7,8-tetrachlorodibenzofuran, PCBs, chlordanes, chloronaphthalenes, hexachlorobenzene and polychlorodiphenyl ethers had no significant trend. Contents of three hexa- and two heptachlorodibenzofurans and octachlorodibenzofuran increased slightly from 1987 to 1994, but then at very high rate from 1994 to 1998. Trends of HCHs, profiles of PCBs and levels of chlordanes are in accordance with atmospheric long range transport. The hexa-, …
Implications of terrain resolution on modeling rainfall-triggered landslides using a TIN- based model
2021
Abstract This study employs a distributed eco-hydrological-landslide model, the tRIBS-VEGGIE-Landslide, to evaluate the influence of terrain resolution on the hydro-geomorphological processes involved in slope stability analysis. The model implements a Triangulated Irregular Network (TIN) to describe the topography starting from a grid-DEM. Five grid-DEM resolutions of the case study basin, i.e., 10, 20, 30 and 70 m, are used to derive the corresponding TINs. The results show that using irregular meshes reduces the loss of accuracy with coarser resolutions in the derived slope distribution in comparison to slope distributions estimated from the original grid-based DEM. From a hydrological p…
Islands of biogeodiversity in arid lands on a polygons map study: Detecting scale invariance patterns from natural resources maps.
2016
Many maps (geology, hydrology, soil, vegetation, etc.) are created to inventory natural resources. Each of these resources is mapped using a unique set of criteria, including scales and taxonomies. Past research indicates that comparing results of related maps (e.g., soil and geology maps) may aid in identifying mapping deficiencies. Therefore, this study was undertaken in Almeria Province, Spain to (i) compare the underlying map structures of soil and vegetation maps and (ii) investigate if a vegetation map can provide useful soil information that was not shown on a soil map. Soil and vegetation maps were imported into ArcGIS 10.1 for spatial analysis, and results then exported to Microsof…
Environmental activism as counter-hegemony? A comparative critical discourse analysis of self-representations of radical environmental organisations
2021
Działalność organizacji ekologicznych wiąże się z odrzucaniem zapewnień o wystarczających działaniach ochronnych i kwestionowaniem dominujących praktyk kulturowych. Jednak aby skutecznie mobilizować opinię publiczną, ruchy ekologiczne muszą prezentować się jako wiarygodne i akceptowalne, choć ich dążenia kwestionują wartości kultury hegemonicznej. Niniejsze studium to analiza porównawcza manifestów trzech radykalnych organizacji ekologicznych, Extinction Rebellion (UK) Deep Green Resistance (USA) i Pracowni na Rzecz Wszystkich Istot (Polska), pod kątem językowych, retorycznych i wizualnych strategii prezentacji wartości opozycyjnych do głównego nurtu kultury w kontekście kryzysu klimatyczne…
L’apparato effimero allestito nella cattedrale di Palermo per le cerimonie funebri di Carlo III di Borbone (1789): storia e rappresentazione digitale
2022
The paper focus on the ephemeral apparatus realized by the architect Salvatore Attinelli on the occasion of the funeral of Charles III of Bourbon, to be set up inside the cathedral of Palermo, in those years affected by a total internal modernization based on the project commissioned in 1767 to Ferdinando Fuga. This apparatus, in an article published by the academic Giuseppina Leone in 2001, was considered an alternative project to the proposal of Ferdinando Fuga, considered expensive and with a language not responding to the rules of good and modern architecture. The purpose of this paper is to reinforce the hypothesis of an apparatus having design purposes, and to verify its feasibility t…
IC‐P‐024: Localization of hippocampal atrophy in Alzheimer's disease
2011
The hippocampus presents the highest rate of atrophy in the early stage of Alzheimer's disease (AD), with more pronounced neuron loss reported in CA1 and subiculum. The aim of this study is to increase the discrimination power of hippocampal shape analysis between AD and normal controls (NC) by focusing on the subregions with atrophy associated with AD and describing the localized shape changes using statistical shape models (SSMs).
