The present work evaluated the conservation of Campomanesia adamantium seeds under different conditions. The fruits used in the study were collected from matrices located in the city of Ponta Porã-MS, Brazil. After processing, the seeds were slowly dried to different water content levels and subsequently exposed to various environmental conditions: 25°C ± 2°C, 35% relative humidity (laboratory); 16°C ± 1°C, 40% relative humidity (cold and dry); 8°C ± 1°C, 35% relative humidity (refrigeration); and -18°C ± 1°C, 42% relative humidity (freezing). Each treatment was conducted for 0 (recently processed seeds, with superficial drying of 40 minutes), 30, 60, 90, 120, 150, and 180 days. Seed potential was physiologically evaluated based on radicle protrusion, percentage of normal seedlings, seedling length (primary root, shoot and total), and dry mass of the seedlings. The experimental design was a completely randomized factorial scheme with split-split plots (4 temperatures/environments × 5 water content × 7 storage periods). C. adamantium seeds tolerated a reduction in the water content to 15.3% but did not tolerate the storage period, confirming the recalcitrant behavior of the seeds.

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...
