This variation highlights the need for high-resolution, small-area demographic data to address the challenges posed by shifting population dynamics, urbanization, and migration. Small area population modelling, particularly the production of gridded population estimates, has advanced rapidly over the past decade. Gridded population estimates rely heavily on the availability of detailed geospatial ancillary datasets to capture, inform and explain the variabilities in population densities and distributions at small area scales, enabling the disaggregation from areal unit-based counts. Here we describe an extensive geospatial collection of annual, high resolution, spatio-temporally harmonised, global datasets aimed at driving improvements in mapping small area population density variation. This article presents the spatio-temporal harmonisation process that results in an open access repository of 73 individual gridded datasets addressing topography, climate, nighttime lights, land cover, inland water, infrastructure, protected areas as well as the built-up environment on a global level at a spatial resolution of 3 arc-seconds (approximately 100 metres). Datasets are available as annual time series from 2015 up to and including at least 2020, and as recent as 2023 where source datasets allow. Such datasets not only support population modelling but also applications across environmental, economic, and health sectors, supporting informed policy-making and resource allocation for sustainable development.</p>","PeriodicalId":12593,"journal":{"name":"Gates Open Research","volume":"9 ","pages":"72"},"PeriodicalIF":0.0,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12444015/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145112579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Other studies have argued that the reversal of fortune has also occurred over time and space. Since different areas of current Nigeria were once under the rule of states with different degrees of political centralization and later investment in Koranic, this study seeks to explore whether areas or districts under a more centralized political system are more likely to participate in large-scale school expansion programs, such as the 1976 Universal Primary Education (UPE) and 1999 Universal Basic Education (UBE). To check for evidence of the reversal of fortune, we determine whether the degree of state centralization on school participation is more or less in areas that have large investments in Koranic education. OLS results show that while an index of state centralization has a positive and significant impact on enrolment in UPE and UBE programs, the effect is negative and statistically significant for those with heavy investment in Koranic education (measured by district fraction of 1914-46 cohorts with Koranic education). The results are robust to adding an extensive range of explanatory variables and specification tests. While the structure of the economy at the onset of Islamic activities in Nigeria may have made investment in Koranic education worthwhile, the contemporary world does not require Koranic education to make either regional or national advancement possible. Thus, there is a clear case of mismatch between the demands of modern economic life and the skills possessed by a large section. Thus, well-designed policies are required to address this mismatch and accelerate inclusive economic development.</p>","PeriodicalId":12593,"journal":{"name":"Gates Open Research","volume":"9 ","pages":"67"},"PeriodicalIF":0.0,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12391587/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144950510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response to the emergence of insecticide resistance in major malaria vectors, novel chemistries and products are coming to market, and there is a need to review the available testing methodologies.

Innovation to Impact (I2I) has studied the variability in laboratory methods, with the aim of identifying key factors that contribute to variation and providing recommendations to tighten up protocols. The I2I Methods Landscape is a living document which presents a review of existing methods for evaluating vector control tools, with the scope currently extending to insecticide-treated nets (ITNs) and indoor residual sprays (IRS). The review reveals a lack of validation for many commonly used vector control methods, highlighting the need for improved protocols to enhance reliability and robustness of the data that is generated to make decisions in product development, evaluation, and implementation. A critical aspect highlighted by this work is the need for tailored methods to measure endpoints relevant to the diverse modes of action of novel insecticides. I2I envisage that the Methods Landscape will serve as a decision-making tool for researchers and product manufacturers in selecting appropriate methods, and a means to prioritise research and development.

Kenya's education system has experienced tremendous changes and diversification over the years, from replacing the old curriculum with the 8-4-4 system, and later transitioning to a competency-based curriculum, not to mention an overhaul of TVET via the Technical and Vocational Education and Training Act No. 29 of 2013. Due to these reforms, enrolment in TVET institutions has progressed upward over the past five years. The growth of the TVET sector has been promoted to help curb the rising rates of youth unemployment, but the evidence of the effectiveness of reforms to date has been sparse. The study provides evidence on two issues: (i) the effect of TVET on youth employment relative to academic education and (ii) the structure and status of the TVET sector in Kenya. We used quantitative and qualitative methodologies to generate the evidence. Findings demonstrate that youth with a TVET background have strong prospects of securing employment than those without TVET skills.
