Blockchain Technology - China\u27s Bid to High Long-Run Growth

Despite having the second largest economy at $13 trillion, China has only recently surpassed the World Bank’s definition of the ‘middle-income range’ which is a gross national income per capita between$1,000 to $12,000 (constant 2011 international$). This is a noteworthy accomplishment since many other developing nations have fallen victim to economic stagnation within this range leading to the term “middle-income trap”. This paper will argue that one of the ways in which China escaped the middle-income trap and will continue to grow its economic influence is through the support of blockchain technology. Research and development, early technological adoption and business climate all play a role in explaining how the Chinese public and private sector have used blockchain technology to encourage economic growth. While there are many questions and misconceptions about blockchain technology and its place in China, this paper seeks only to answer a select few

Two loop Kahler potential in beta-deformed N=4 SYM theory

In N=2 superconformal field theories the Kahler potential is known to be tree level exact. The beta-deformation of N=4 SU(N) SYM reduces the amount of supersymmetry to N=1, allowing for non-trivial, superconformal loop corrections to the Kahler potential. We analyse the two-loop corrections on the Coulomb branch for a complex deformation. For an arbitrary chiral field in the Cartan subalgebra we reduce the problem of computing the two-loop Kahler potential to that of diagonalising the mass matrix, we then present the result in a manifestly superconformal form. The mass matrix diagonalisation is performed for the case of the chiral background that induces the breaking pattern SU(N) -> SU(N-2)*U(1)^2. Then, for the gauge group SU(3), the Kahler potential is explicitly computed to the two-loop order.Comment: 24 pages, 1 figure, version published in JHE

Transforming Accra towards a Sustainable Future: Comprehensive Land Use Planning and the Greater Accra Urban Simulation System (GAUSS)

The urbanization of Sub-Saharan Africa is occurring more rapidly than in any other region in the world, at a historically unprecedented absolute rate of increase, within an institutional framework desperately lacking in resources. In step with its Sub-Saharan location, Ghana is experiencing unprecedented urbanization with currently 50% of its 23 million people living in urban areas; that share is expected to become 65% by 2030. The lion’s share of this growth is taking place in the administrative and commercial center, Accra, which has a population of more than three million people. It is exhibiting a growth rate in excess of 4% per year and is expected to double its population within 16 years

One King to Rule Them All

He battled for superiority over his fellow musicians in the shady nightclubs of New Orleans, led his great Creole Jazz Band in the early 1920s, and stood tall in the face of racial prejudice. Joe “King” Oliver was the type of man to not just survive but thrive—like any true king would
