Promoting Women’S Land Ownership Rights In Tanzania: The Role Of Wlac As A Legal Empowerment Ngo, Norbeth Sixbert Nov 2025

Promoting Women’S Land Ownership Rights In Tanzania: The Role Of Wlac As A Legal Empowerment Ngo, Norbeth Sixbert

Young African Leaders Journal of Development

Despite Tanzania's progressive legal frameworks that recognize women's rights to own and inherit land, significant gaps remain between policy and practice. This paper explores the role of Non-Governmental Organizations (NGOs) in promoting women's land ownership rights, using the Women's Legal Aid Centre (WLAC) as a case study. Located in Kinondoni Municipal, Dar es Salaam, WLAC employs a multifaceted approach that empowers women and safeguards their land rights. While WLAC has achieved notable success, challenges exist and are exacerbated by overlapping statutory and customary legal systems that often disadvantage women. WLAC's multilateral engagement has helped to navigate these obstacles, yet structural …

Coup-Proofing As A Tool For Authoritarian Survival In Central Africa: A Comparative Study Of Teodoro Obiang In Equatorial Guinea And Paul Biya In Cameroon, Prince Ifoh

Young African Leaders Journal of Development

For many African leaders, the most serious threat to their rule does not come from elections or public protests but from the people closest to them—the military and ruling elites. This paper examines how Teodoro Obiang Nguema of Equatorial Guinea and Paul Biya of Cameroon have remained in power for more than four decades by carefully reshaping their security institutions in ways that minimize coup risks. Drawing on established theories of authoritarian survival and a comparative analysis of both regimes, the research shows that they rely on a deliberate set of coup-proofing tactics, including the placement of trusted allies in …

Inverse Design For Generating Initial Conditions In Scientific Simulations, Leslie Horace, Christin Whitton, Vanessa Job, William Jones, Nathan A. Debardeleben Nov 2025

Inverse Design For Generating Initial Conditions In Scientific Simulations, Leslie Horace, Christin Whitton, Vanessa Job, William Jones, Nathan A. Debardeleben

Computing Sciences

We propose a conditional normalizing flow (CNF) surrogate model to solve generative, many-to-one inverse problems in scientific simulations governed by partial differential equations (PDEs) with time-evolving interactions between heterogeneous materials. We present two case studies: electrostatic potential and heat diffusion, which serve as proxy simulations for generating diverse sets of initial conditions that can reproduce an observed output state (transient or steady). Finally, we provide a comprehensive overview of the synthetic datasets, the model specification, each stage of the experimental workflow, evaluation of training performance, and uncertainty quantification for the generated samples.
