Understanding Difference to Build Bridges among Stakeholders: Perceptions of Participation in Four Multi-stakeholder Forums in the Peruvian Amazon by Sarmiento Barletti, J.P., Larson, A.M., Heise Vigil, N.

“…The academic literature on their equity largely presents a dichotomy: participatory processes either allow for horizontal decision-making with more equitable and effective outcomes for local populations, or they mask technologies of governance that do not address – and may reinforce – structures of inequality. …”

Rapid Determination of Gene Function by Virus-induced Gene Silencing in Wheat and Barley by Cakir, Cahid, Gillespie, Megan E., Scofield, Steven R.

“…Additionally, the polyploidy of wheat greatly complicates any approach based on mutational analysis because functional, homeologous genes often mask genetic mutations. Virus‐induced gene silencing (VIGS) is an important new tool that overcomes many of these obstacles and promises to greatly facilitate the assessment of gene function. …”

From IWRM back to integrated water resources management by Giordano, Mark, Shah, Tushaar

“…IWRM has now become an end in itself, in some cases undermining functioning water management systems, in others setting back needed water reform agendas, and in yet others becoming a tool to mask other agendas. Critically, the current monopoly of IWRM in global water management discourse is shutting out alternative thinking on pragmatic solutions to existing water problems. …”

Cassava haplotype map highlights fixation of deleterious mutations during clonal propagation by Ramu, P., Esuma, W., Kawuki, R.S., Rabbi, Ismail Y., Egesi, Chiedozie N., Bredeson, J.V., Bart, R.S., Verma, J., Buckler, E.S., Lu, F

“…We found that (i) although domestication has modified starch and ketone metabolism pathways to allow for human consumption, the concomitant bottleneck and clonal propagation have resulted in a large proportion of fixed deleterious amino acid changes, increased the number of deleterious alleles by 26%, and shifted the mutational burden toward common variants; (ii) deleterious mutations have been ineffectively purged, owing to limited recombination in the cassava genome; (iii) recent breeding efforts have maintained yield by masking the most damaging recessive mutations in the heterozygous state but have been unable to purge the mutation burden; such purging should be a key target in future cassava breeding.…”

The influence of postflowering pests on cowpea seed yield with particular reference to damage by Heteroptera in southern Benin by Dreyer, H., Baumgaertner, J.U.

“…Heavy seed attack by this pest group during early pod formation reduced available food for other pests in many fields and consequently masked their real damage potential. Clavigralla tomentosicollis was the most damaging PSB species in 11 out of 16 fields in the study area.…”

Global Rural-Urban Mapping Project (GRUMP) by International Food Policy Research Institute

“…The data contained here are a preliminary version of the Urban-Rural urban mask. Improved versions will follow. All urban areas with a population of 1,000 persons or more have been included. …”

Comparison of methods to evaluate rice (Oryza sativa) germplasm for tolerance to low temperature at the seedling stage by Sharma, Nirmal, Reinke, Russell, Sacks, Erik J.

“…Moreover, transplanted seedlings at the end of the nine-week mimic protocols showed large differences in height and dry biomass, whereas for the standard protocols, growth during the warm pre-treatment substantially masked these genotypic differences. Thus, initial screening of large rice germplasm panels can be most efficiently accomplished with a short-duration germination test at low temperature. …”

Long-term trends in calcifying plankton and pH in the North Sea by Beare, Douglas J., McQuatters-Gollop, Abigail, Hammen, Tessa van der, Machiels, Marcel, Teoh, Shwu Jiau, Hall-Spencer, Jason M.

“…If there are any effects of pH on calcifying plankton in the North Sea they appear to be masked by the combined effects of other climatic (e.g. temperature), chemical (nutrient concentrations) and biotic (predation) drivers. …”

Knowledge, attitudes and practices study on pig meat hygiene at slaughterhouses and markets in Chiang Mai province, Thailand by Jenpanich, C.

“…There are some contract finding between attitudes and practices; for example food handlers agreed that protective equipment can reduce cross contamination, but they practically do not wear gloves and mask and still work when they got sick. The qualitative data indicated that some good hygiene measures are inappropriate in the context of their practical implementation and some of these hygiene practices are not in accordance with their socio-economic status.…”

Remote sensing approach for spatial planning of land management interventions in West African savannas by Heiskanen, J., Liu, J., Valbuena, R., Aynekulu, Ermias, Packalen, P., Pellikka, P.

“…High spatial resolution RapidEye imagery provided the best accuracy but difference to medium resolution Landsat imagery was negligible for most attributes. Burn scar masked Landsat time series performed similar to dry season single date Landsat imagery, but the former avoids image selection and mosaicking, and could be less sensitive to artifacts due to the burn scars. …”

Evaluating the distributional impacts of drought tolerant maize varieties on productivity and welfare outcomes: an instrumental variable quantile treatment effects approach by Olagunju, K.O., Ogunniyi, A.I., Awotide, B.A., Adenuga, A.H., Ashagidigbi, W.M.

“…Policy measures targeted at tackling dissemination constraints, such as the promotion of informal seed sector, may help enhance the successful dissemination and adoption of DTMVs or any agricultural intervention without masking out any sub-groups.…”

Seed damaging field pests of cowpea (Vigna unguiculata) L.Walp.) in Benin: occurance and pest status by Dreyer, H., Baumgaertner, J.U., Tamo, Manuele

Annual forest cover conditions across the Southwestern Amazon, 2003-2021 by Reygadas, Yunuen

“…As the algorithm uses statistical characteristics of time series to determine the forest conditions in the end of the study period, time series composed of the last 20 years prior to the target year were used in each annual run. A forest mask, composed of all areas covered by forest at least three consecutive years and never covered by water during the 2000-2018 period, was applied to all maps. …”

A typology of food security in developing countries by Yu, Bingxin, You, Liangzhi

“…The analysis first identifies five distinct food security groups, measured by the levels of nutrient intake, and then further splits these groups based on indicators of food production, trade security, and agricultural potential.The results suggest that the terms of “developing country” or “low income country” can be inaccurate in the discussion of food security because they are too general and can actually mask the extreme heterogeneity in different aspects of food security. …”

Beyond “More Crop per Drop”: evolving thinking on agricultural water productivity by Giordano, Meredith A., Turral, Hugh, Scheierling, S.M., Treguer, D.O., McCornick, Peter G.

“…Yet, reliance on a single-factor productivity metric, such as agricultural water productivity defined as “crop per drop,” in multi-factor and multi-output production processes can mask the complexity of agricultural systems as well as the trade-offs required to achieve desired outcomes. …”

Pigs, people, pathogens: Health and multispecies relations in central Uganda by Thompson, R.G.

Impact of current and historical climate shocks on crop diversification in Zambia: insights from household- and district-level observations by Wang, J., Konar, M., Anderson, P. N., Hadunka, P., Mulenga, B.

“…Simpson’s Diversity Index (SDI) of crops serves as the dependent variable and is consistently higher at the district level than at the household level, suggesting that aggregation at larger scales may mask localized monoculture vulnerabilities. Our findings reveal that both current and historical climate shocks significantly influence crop diversification decisions at both the household and district levels in Zambia. …”
