The Stability

In this paper, a modified optically injected semiconductor lasers model is studied in detail. More precisely, we study the stability of the equilibrium points and basic dynamic properties of the autonomous system by means of nonlinear dynamics theory. The existence of Hopf bifurcation is investigated by choosing the appropriate bifurcation parameter. Furthermore, formulas for determining the stability and the conditions for generating Hopf bifurcation of the equilibria are derived. Then, a numerical example is given.

Economic Cycles

The article considers the ways to overcome the methodological gap between the analysis of economic cycles and the pure economic theory as suggested by the Western economists in the 1920s and 1930s. In this context, N. D. Kondratiev’s project of economic dynamics is analyzed, which implied a radically different vision of the opportunities to solve this problem.

Durable Solutions

Camps are temporal spaces where refugees are provided with humanitarian aid until durable solutions are made possible. During this period of ‘endless waiting’, these camps are planned to be economically self-contained. However, through time, refugee camps tend to urbanise: their initial empty spaces transform into vibrant markets, habitats and social spaces. In response to this ‘unexpected’ - and sometimes ‘unwanted’ - process, the economically self-contained system of camps breaks. This paper looks into the emerging socio-economic dynamics in Zaatari camp in Jordan, on the light of its urbanisation process and the Jordanian economy. It first explains the how humanitarian aid is provided, and then shows how and why, refugees use it to diversify the economy of the camp. The findings of this paper are then articulated on the existing policies to reduce the financial aid such as ‘self-reliance’ and ‘development’.

Dose Levels

ABSTRACT Gaddum's simplified system of computation for the analysis of biological parallel-line assays is extended to the assay of several unknown preparations simultaneously against the same standard, using up to four dose levels of each preparation. Complete working directions and formulae are provided and illustrated by a numerical example. Limiting conditions are briefly discussed.
