Asset Liability Management for Tanzania Pension Funds

Abstract

AbstractMCrAlY coatings (M=Ni and/or Co) have been widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive to improve engine combustion efficiency while reducing emissions by increasing the operation temperature brings a big challenge for coating design. As a result, the need for improvement of MCrAlY coatings for better oxidation resistance is essential.Formation of a stable, dense, continuous, and slow-growing α-Al 2 O 3 layer, on the MCrAlY coating surface, is the key to oxidation protection, since the protective α-Al 2 O 3 scale offers superior oxidation resistance due to its lower oxygen-diffusion rate as compared with other oxides. The ability of a MCrAlY coating to form and maintain such a protective scale depends on the coating composition and microstructure, and can be improved through optimization of deposition parameters, modification of coating surface conditions, and so on. Part of this thesis work focuses on studying the effect of post-deposition surface treatments on the oxidation behavior of MCrAlX coatings (X can be yttrium and/or other minor alloying elements). The aim is to gain fundamental understanding of alumina scale evolution during oxidation which is important for achieving improved oxidation resistance of MCrAlX coatings. Oxide scale formed on coatings at initial oxidation stage and the effect of surface treatment were investigated by a multi-approach study combining photo-stimulated luminescence, microstructural observation and weight gain.

What Influences Pension Funds’ Investment Decisions in Tanzania?

“…Akomea-Frimpong et al (2022) conducted a study examining the relationship between corporate governance practices and the performance of pension funds in Ghana, and revealed that corporate governance practices played a significant role in influencing the performance of pension funds. Mwakisisile (2018) conducted a study on Asset Liability Management (ALM) for Pension Funds in Tanzania, and revealed that the pension fund would face sustainability challenges in the long run due to the increased life expectancy of its members, and that in order to enhance the long-term sustainability of the Tanzania pension fund system, reforms were necessary in several areas such as contribution rate, investment guidelines, and the formulation of target levels (funding ratios) to assess the solvency situation . The study insisted that implementing such reforms would contribute to improving the overall sustainability of the pension system in Tanzania.…”

Factors affecting ability and willingness of community members to enrol Improved Community Health Fund in Dodoma and Iringa regions

“…Regardless of of such efforts taken so far, still the government is far from achieving the Universal Health Coverage (UHC) due to a small population that is currently granted with access to health services as only few people are currently under health insurance coverage. To date, out of the country population (57,637,628) (Mwakisisile & Mushi, 2020) only 8 percent is enrolled with NHIF, 5.4 percent is covered under CHF, 0.3 percent covered by SHIB (NSSSF) and 1 percent being enrolled under private health insurance companies (Kibambo, 2021). This leads to the total of 14.7 percent as country coverage.…”
