The business model through an ecosystem perspective: An exploratory approach applied to a cultural card
This paper aims to explore the relationship between the concepts of business model and ecosystem, applied to the creation of cultural cards that generate symbolic, cultural, social and economic value. This is a hybrid study - conceptual and empirical - and exploratory, based on literature review and data analysis collected by 602 questionnaires and 27 interviews. Was conducted a mixed methodology, qualitative and quantitative, and an interpretivist paradigm of constructivist nature. Three main conclusions were drawn. The first suggests that a cultural card is only viable if designed and managed as a business model, with all blocks coherent and articulated with each other and executed in synchronization. The second configures a cultural card as a complex network of interdependent actors functioning in an ecosystem logic that enhances economic growth affirmed by creative competitiveness. The third points out a cultural card as a cultural agent, for the symbolic value it promotes dominated by the discourse of ‘now’ and ‘already’, inherent in the access-based economy This paper: (1) perspectives that cultural and creative development involves the creation of a valuable macro ecosystem and a robust national network articulated with local and specific micro ecosystems; (2) evidences the importance of creativity and innovation, inherent to the business model, for the production and diffusion of knowledge, fruition and democratization of culture in the face of the diversity of emerging market segments and (3) provides propositions applicable to the universe of cultural and creative industries that are carriers of new insights that can be explored and knowledge increased. The value of this paper lies in the exploration of a new look at the theme of cultural cards embodied in a logic of an ecosystemic business model.info:eu-repo/semantics/publishedVersio
Qualitative analysis of a scalar-tensor theory with exponential potential
A qualitative analysis of a scalar-tensor cosmological model, with an
exponential potential for the scalar field, is performed. The phase diagram for
the flat case is constructed. It is shown that solutions with an initial and
final inflationary behaviour appear. The conditions for which the scenario
favored by supernova type Ia observations becomes an attractor in the space of
the solutions are established.Comment: Latex file, 9 pages, 1 figur
Framework for performance assessment of wind farms
This study develops a framework to provide insights regarding the performance of the farms of
an energy player in the Portuguese wind sector. Firstly, the Data Envelopment Analysis is used
to measure the efficiency of wind farms in producing electrical energy from the resources available
and exogenous variables, during operating stage. This analysis enables the identification of the best
practices of the efficient farms which can be emulated by inefficient ones. Secondly, Malmquist index
is used to evaluate the changes in wind farms productivity. Bootstrap procedures are applied to
obtain statistical inference on the efficiency estimates
Efficiency and productivity assessment of wind farms
This study develops a framework to provide insights regarding the
performance of the farms of an energy player in the Portuguese wind sector. The
focus of the wind farm performance assessment is on the operating stage which
corresponds to the electrical energy generation process, during 2010 and 2011.
In a first stage, Data Envelopment Analysis is used to measure the efficiency of
wind farms in generating electrical energy from the resources available and nondiscretionary
variables. This analysis enables the identification of the best practices
of the efficient farms which can be emulated by inefficient ones. In a second
stage, changes in wind farms productivity are investigated using Malmquist index.
Bootstrap procedures are applied to obtain statistical inference on the efficiency
estimates. We conclude that almost all farms decreased overall productivity levels,
mainly due to the decline in the productivity levels of the frontier, which is in
accordance with the decrease in wind availability observed in 2011.info:eu-repo/semantics/publishedVersio
