Abstract “Queer” is a relatively recent and somewhat controversial term in African studies. Yet it proving to be productive, not only for understanding subjectivities of sexuality gender, but also situating Africa’s position the larger economy knowledge. Otu van Klinken explore productive tensions between “queer” “Africa,” aim read Africa as queer from Africa. Thus, rather than imagining polar ...

Rich-club and page-club coefficients and their null models are introduced for directed graphs. Null models allow for a quantitative discussion of the rich-club and page-club phenomena. These coefficients are computed for four directed real-world networks: Arxiv High Energy Physics paper citation network, Web network (released from Google), Citation network among US Patents, and Email network fr...

background: running standard journal clubs is one of the important goals of postgraduate education. students should update their knowledge and learn critical appraisal skill. this study aimed to compare quality of journal clubs in mashhad dental school in order to improve educational and appraisal structure of journal clubs. methods: this quasi-experimental study was conducted on journal clubs ...

This paper presents a coordinated approach for increasing the end-to-end availability of inter-domain paths. Major reasons for intermittent failures are frequent inter-domain route changes and their long convergence times. The first part of our solution reduces the need for inter-domain path changes by introducing the Resilient Chain. The two other mechanisms — Fast Scoped Rerouting and Virtual...

Drug abuse is often seen as a unitary phenomenon, partly as a result of the discovery over the past three decades of shared mechanisms of action for addictive substances. Yet the pattern of drug taking is often very different from drug to drug. This is particularly evident in the case of 'club drugs', such as ketamine. Although the number of ketamine abusers is relatively small in the general p...

We discuss the convergence property of the minimum residual (MINRES) method for the solution of complex shifted Hermitian system (αI + H)x = f . Our convergence analysis shows that the method has a faster convergence than that for real shifted Hermitian system (Re(α)I +H)x = f under the condition Re(α) + λmin(H) > 0, and a larger imaginary part of the shift α has a better convergence property. ...

The impact of COVID-19 on the economy and business is a major issue. We define convergence clubs as countries with same service turnover by using algorithm for testing clustering. repeat procedure in hospitality food industry, information communication, transport, storage. each club identified study varies empirically. findings suggest that between industries depending firm’s agility, innovatio...

The paper presents a model of technology adoption with endogenous supply of human capital. I investigate the effects of skill bias technical change in the frontier economies on the evolution of output, the quantity and quality of human capital in the adopting countries. The framework introduces a novel feature by connecting the direction of technology adoption to a sequential process of skill a...
