The Current Standing and Future Prospects of ARTS and Culture in Ethiopia
This research article explores the current state of affairs of arts and culture sector in Ethiopia. An in-depth analysis of various dimensions of art and culture highlights where the country is presently lacking in governance and socio-economic progress in the sector.
A qualitative research was carried out to collect primary data. 52 respondents were chosen to be interviewed from Bahir Dar University by the method of quota sampling and the results were analyzed. Secondary data was also analyzed through academic literature from universities in Ethiopia, reports from government and development organizations. Survey results and existing academic literature have guided to single out major hindrances to this sector.
In this research it can be confirmed, that the arts and culture sector needs a major intervention in terms of governance and marketing. This research gives out a very structural strategy, based on cultural governance, cultural economics and strategies of new business development as it pillars to support the prosperity of this sector in Ethiopia.
The existing academic research provides data on different arts and culture and problems which are specific to a particular region of the country. Whereas this article goes a step further in enforcing the ordinance of cultural governance to the responsible government bodies both locally and nationally and simultaneously highlights how economic progress can be achieved through this sector. Cultural governance as a directive has never been implemented in transition economies and this article will serve as a directive for the future. This article shall be very beneficial for further research in this sector and structuring the work of government bodies, stake holders and the people involved in the sector within Ethiopia
Transient features of quantum open maps
We study families of open chaotic maps that classically share the same
asymptotic properties -- forward and backwards trapped sets, repeller
dimensions, escape rate -- but differ in their short time behavior. When these
maps are quantized we find that the fine details of the distribution of
resonances and the corresponding eigenfunctions are sensitive to the initial
shape and size of the openings. We study phase space localization of the
resonances with respect to the repeller and find strong delocalization effects
when the area of the openings is smaller than .Comment: 7 pages, 7 figure
Entangling power of baker's map: Role of symmetries
The quantum baker map possesses two symmetries: a canonical "spatial"
symmetry, and a time-reversal symmetry. We show that, even when these features
are taken into account, the asymptotic entangling power of the baker's map does
not always agree with the predictions of random matrix theory. We have verified
that the dimension of the Hilbert space is the crucial parameter which
determines whether the entangling properties of the baker are universal or not.
For power-of-two dimensions, i.e., qubit systems, an anomalous entangling power
is observed; otherwise the behavior of the baker is consistent with random
matrix theories. We also derive a general formula that relates the asymptotic
entangling power of an arbitrary unitary with properties of its reduced
eigenvectors.Comment: 5 page
