This report presents a case of propriospinal myoclonus (PSM) in a previously fit and well female patient who presented with truncal jerking movements when relaxed. Propriospinal myoclonus is a rare condition, of which 80% of the aetiology is idiopathic. It is characterised by involuntary jerking movements of the trunk due to spreading activity via intrinsic propriospinal pathways along the spinal cord. Polymyography is mandatory in the diagnosis of priopriospinal myoclonus however in discerning the differential diagnoses it is inferior to magnetic resonance diffusion tensor imaging. The management of propriospinal myoclonus is dependent on aetiology. Clonazepam has been shown to be effective in the treatment of idiopathic PSM for symptomatic relief.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education.
