The impact of rotavirus (RV) vaccination in reducing severe rotavirus gastroenteritis (RVGE) in outpatient settings was prospectively surveyed in three pediatric clinics in Shibata City. In children younger than 3 years of age, the occurrence of severe RVGE among all acute gastroenteritis (AGE) was found to be significantly lower in three seasons after introduction of RV vaccines, compared to that in 2011, before introduction of RV vaccines. The incidence rates of severe RVGE among children younger than 3 years of age were found to be reduced by 71.2%, 47.7%, and 81.1% for 2012, 2013, and 2014, respectively, compared to that in 2011. These results suggest that the RV vaccination is effective for the prevention of severe RVGE in Japanese voluntary RV vaccination settings with estimated coverage rates of 32.5%, 40.5% and 47.1% for 2012, 2013 and 2014, respectively. It is expected that the reducing effect on severe RVGE would be persistently established by increasing the vaccine coverage rates.

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. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
