The influence of environmental cues on behavioral response: An assessment of the Protective Action Decision Model in the context of COVID-19 by Silver, Amber, Koyratty, Nadia, Penta, Samantha, Clay, Lauren

“…Accordingly, this research utilizes an online questionnaire instrument disseminated via Qualtrics to residents of New York State at three points in the COVID‐19 pandemic (October 2020, January 2021, and May–June 2021) to examine whether changes to the built environment (i.e., signs requiring masking, signs requiring social distancing, and presence of hand sanitizing stations) influenced threat perceptions (i.e., perception of severity and likelihood of infection), and in turn, behavioral responses (i.e., masking, social distancing, and hand sanitizing) at different points in time. …”

Rainfed wheat extent (2020/21) across Ethiopia's complex and highly fragmented agricultural smallholder landscape by Blasch, Gerald, Lesne, Louise, Wolter, Jolan, Alemayehu, Yoseph, Bontemps, Sophie, Hodson, David, Defourny, Pierre

“…This study presents the first national-scale, high-resolution wheat area map for Ethiopia, generated through a satellite-based workflow integrating (i) gap-filled, cloud-masked Sentinel-2 time series; (ii) Random Forest classification using temporal-spectral profiles and the EthCT2020 reference dataset; (iii) cropland masking; (iv) multistep validation; and (v) confidence-based consolidation with sub-national statistics. …”

Farm records and work planning on agricultural research farms by Couper, D.C.

“…Research scientists must have access to field records to ensure that their experimental treatments are neither masked nor affected by previous land usage. Research fields must be identified on the ground and accurate records kept of all operations and treatments carried out. …”

Water scarcity variations within a country: a case study of Sri Lanka by Amarasinghe, Upali A., Mutuwatte, L.P., Sakthivadivel, Ramaswamy

“…Statistics in the form of aggregated information at national level sometimes mask issues of local water scarcity. But when the same indicators are used at subunit level, a substantial area of the country comes under severe water-scarce conditions. …”

Efficiency and status in polygynous pastoralist households by Hidrobo, Melissa, Hoel, Jessica B., Wilson, Katie

“…However, average contributions at the household level mask differences across dyads. Junior wives receive less but give more to their husbands than senior wives, leaving junior wives worse off than other household members.…”

El Cryptolaemus Montrouzieri Muls. Parásito del Pseudococcus Citri Risso by Gómez-Clemente, Federico

“…El buen resultado de la campaña biológica contra Icerya purchasi Mask. plaga que prácticamente ha sido dominada con la aclimatación del coccinélido australiano Novius cardinalis Muls., movió a esta Estación de Patología Vegetal a continuar la introducción de aquellos insectos que se señalaban como capaces de actuar favorablemente al combatir 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.…”

The Impact of Bolsa Família on Schooling by de Brauw, Alan, Gilligan, Daniel O., Hoddinott, John F., Roy, Shalini

“…Weak aggregate effects mask considerable heterogeneity. Among girls, the program significantly increases school participation (by 8 percentage points) and grade progression (by 10 percentage points), with large, significant effects across both younger and older girls in rural areas but concentrated among girls aged 15–17 years in urban areas. …”

Linking spatio-temporal variation of crop response with sediment deposition along paddy rice terraces by Schmitter, P., Dercon, G., Hilger, T., Hertel, M., Treffner, J., Lam, N., Duc Vien, T., Cadisch, Georg

“…Furthermore, where the effect of inherent soil fertility on rice productivity is masked by soil water or nitrogen availability, the use of 13C and 15N stable isotopes and its integration with conventional techniques showed potential to enhance the understanding of the influence of erosion – sedimentation and nutrient fluxes on crop productivity, at toposequence level…”

Alternative pathway activation of complement by African trypanosomes lacking a glycoprotein coat by Ferrante, A., Allison, A.C.

“…The results suggest that the glycoprotein surface coat protects the parasite by masking sites on the plasma membrane which are capable of promoting alternative pathway activation.…”

Fattening mature indigenous (Matabele) goats: effects on animal performance, body and carcass composition by Hatendi, P.R., Smith, T., Ndlovu, L., Mutisi, C.

“…Means of performance traits had high coefficients of variation and it is suggested that the heterogeneity of the sample population may have masked treatment effects.Compared to the preliminary slaughter group, carcass mass and yield was significantly (P<0.05) increased by feeding as was fat deposition in both visceral and carcass depots. …”

Etablering av oljerättika och mätning av markmotstånd vid djupluckring alternativt plöjning by Andersson, Josefin, Larsson, Markus

“…En iakttagelse som gjordes vid uppgrävningen av oljerättikan, var att i alla de djupluckrade försöksrutorna på de två försöksplatserna fanns det mask. I de plöjda försöksrutorna upptäcktes inte en enda mask.…”

Water quality and food safety: A review and discussion of risks by Jawahar, Puja, Ringler, Claudia

“…While increased diversification of developing-country diets as a result of agricultural and economic growth has improved nutritional status and human health, the increased consumption of high-value products—particularly fresh fruits, vegetables, dairy and animal products—has lead to significant food safety risks associated with unsafe management and use of water resources These risks are both magnified and masked in developing countries due to a lack of regulation combined with a dearth of data and information on the relations between water use, water quality and food safety risks. …”
