Modeling Inflation Jumps And Regimes In Ghana: Evidence From Hidden Markov Models, Hawkes Processes, And Jump Dependence Tests
This paper examines Ghana's inflation dynamics using a combination of regime switching and self-exciting point process models, complemented with formal jump-dependence tests. A Gaussian Hidden Markov Model (HMM) is applied to monthly Consumer Price Index (CPI) year-on-year changes to identify latent inflation regimes. Structural jump events are detected using change-point methods, and their temporal dependence is analyzed through a univariate

Digital Financing Systems And Liquidity Of Public Secondary Schools In Machakos County; Kenya
Liquidity management continues to present a major challenge for Kenyan public secondary schools, despite sustained government interventions such as the Free Day Secondary Education (FDSE) program. Although FDSE provides critical financial support, many schools still face persistent irregularities in cash flows arising from delayed government disbursements and unpredictable parental fee payments. These disruptions limit the capacity of institutions to meet

Comparative Evaluation Of Three Infiltration Models In Selected Locations In Imo State, Nigeria
Infiltration, the process governing the movement of water from the soil surface to subsurface layers, is fundamental to hydrological processes, irrigation planning, and erosion control. This study comparatively evaluated three widely applied infiltration models-Horton, Philip, and Green-Ampt-using field measurements from selected locations in Imo State, Nigeria. Double-ring infiltrometer experiments were conducted, and key soil physical parameters, including particle size distribution,

Modeling Interest Rate Volatility In Ghana Using Markov-switching (ms) Model
This study applies Markov-Switching (MS) models to Ghana's key interest rate series covering January 2000 to August 2025. The goal is to identify latent volatility regimes, estimate regime-specific parameters, and interpret structural breaks within the context of macroeconomic and policy events. The analysis finds strong evidence of regime shifts, typically corresponding to major economic disruptions such as the global financial

Administrative Discipline And Stress Control In Sports Development In The Nigeria Athletic Federation (naf)
This study investigated the influence of administrative discipline and stress control on sports development in the Nigeria Athletic Federation (NAF). The study was prompted by persistent concerns about declining performance, ineffective talent grooming, and administrative inefficiencies within the Federation, which are often attributed to poor discipline and unmanaged stress among personnel. A descriptive correlational survey research design was adopted. The
