Mapping the risky returns to smallholder fertilizer investments in Africa por Gebrekidan, Bisrat, Chamberlin, Jordan, Mkondwa, Maxwell, Silva, Joao Vasco, Hijmans, Robert

“…A central challenge is that fertilizer decisions are made under substantial production and market uncertainty, yet most policy targeting and advisory tools rely on average profitability metrics that mask exposure to downside risk. This paper develops a spatially explicit, ex ante framework to support risk-informed fertilizer policy and investment decisions under rainfed smallholder conditions. …”

A sub-national hunger index for Ethiopia: Assessing progress in region-level outcomes por Schmidt, Emily, Dorosh, Paul A.

“…Because national averages can mask important regional differences, we calculate a Sub-National Hunger Index for Ethiopia using data from 1999-2000 and 2004-05 (the latter year being the latest for which nationally representative household surveys are available). …”

Impact of orphanhood on underweight prevalence in sub-Saharan Africa por Rivers, Jonathan, Mason, John, Silvestre, Eva, Gillespie, Stuart, Mahy, Mary, Monasch, Roeland

“…Although evidence indicates that orphans risk losing opportunities for adequate education, health care, and future employment, the immediate effects of orphanhood on child nutritional status remain poorly understood.This paper assesses the nutritional impact of orphanhood, with particular emphasis on taking account of various factors potentially confounding or masking these impacts.Child anthropometry and orphan status were examined in 23 Multiple Indicator Cluster Surveys and Demographic and Health Surveys throughout sub-Saharan Africa, which were subsequently merged into larger, region-specific datasets (East, West, and Southern Africa). …”

A bottom-up framework for assessing greenhouse gas emissions and mitigation potential in food systems por Kakai, L.F., Noufa, C.K., Sapkota, T.B., Corbeels, M., Choptiany, J.M.H.

“…National inventories typically rely on aggregated activity data and default emission factors, which obscure local heterogeneity, mask emission hotspots, and provide limited guidance for subnational planning and implementation. …”

Post-translational signal peptide cleavage controls differential epitope recognition in the QP-rich domain of recombinant Theileria parva PIM por Casanova, C.L., Xue, G., Taracha, E.L.N., Dobbelaere, D.A.E.

“…Depending on the presence or the absence of the signal peptide, two conformational states could be demonstrated that are differentially recognized, with N-terminal epitopes becoming readily accessible upon signal peptide removal, and C-terminal epitopes becoming masked. Similar observations were made when the QP-rd of PIM was expressed in bacteria. …”

Annual water, sediment, nutrient and organic carbon fluxes in river basins: a global meta-analysis as a function of scale por Mutema, M., Chaplot, V., Jewitt, G.P.W., Chivenge, Pauline P., Blöschl, G.

“…Climate was a major control masking the effects of other factors. For example, RC, SL, TOCL, TNL, and TPL tended to increase with MAP at all spatial scales. …”

Interdependence in rainwater management technologies: an analysis of rainwater management adoption in the Blue Nile Basin por Gebregziabher, Gebrehaweria, Rebelo, Lisa-Maria, Langan, Simon J.

“…Our results suggest that rainwater management technologies are related with each other; hence, any effort to promote the adoption of rainwater management technologies has to consider such interdependence of technologies, or failure to do so may mask the reality that farmers face a set of choices in their adoption decisions.…”

Aclimatación en España del «Cryptolaemus montrouzieri muls., para combatir el «cotonet» del naranjo por Gómez-Clemente, Federico

“…El buen resultado de la campaña de lucha biológica contra la «cochinilla australiana» (Icerya Purchasei Mask), plaga que, prácticamente, ha sido dominada con la aclimatación del coccinélido Novius cardinalis Muls., movió a esta Estación de Patología Vegetal a continuar la introducción de aquellos insectos que se señalaban como de empleo posible y práctico para combatir las plagas generalizadas en la región valenciana, al mismo tiempo que a realizar estudios encaminados a encontrar parásitos indígenas de los insectos que atacan al naranjo. …”

Development of anthocyanin markers: gene mapping, genomic analysis and genetic diversity studies in Ipomoea species por Arizio, Carla Marcela, Costa Tártara, Sabrina María, Zunino, Ignacio, Manifesto, Maria Marcela

“…Purple sweet potatoes have anthocyanins as the predominant colour, even though they are present in orange roots masked by carotenoids. Several studies have focused on molecular aspects of anthocyanin genes, mainly in wild Ipomoea species, although the structure and segregation analysis of those genes in sweet potato hexaploid species are still unknown. …”

Variability of flowering sex and its effect on agronomic trait expression in white guinea yam por Iseki, K., Matsumoto, R., Olaleye, O., Shimizu, M., Asfaw, A.

“…This might be due to the high heterozygosity of yam where cultivars with different flowering sex have different genetic backgrounds, which mask the sole effect of sex phenotype on the agronomic traits. …”
