description: As a new food delivery system has emerged to capture a larger share of the industry's sales, the online food delivery sector has risen. This new business delivery system has gained widespread acceptance, particularly among young, active, and hardworking individuals. Furthermore, this business has become more competitive due to the increasing number of new business entries and the expectations of users as a result of the anxiety associated with online ordering and the convenience of ordering at any time. In order to succeed in this emerging market, Customers require online service providers to understand the true nature and requirements of their customers and all essential points of the online service industry. This study aims to gather the information that will assist online food service providers to understand the requirements and characteristics of this new service delivery system, which is currently under development. The purpose of this study is to examine the relationships between customers' perceived service quality for online food delivery and its effect on customer satisfaction by adopting a questionnaire from the Mobile Service Quality Study (M-S-QUAL).
Modeling Surface Runoff and Evapotranspiration using SWAT and BEACH for a Tropical Watershed in North Vietnam, Compared to MODIS Products

description: Accurate estimation of surface runoff (Q) and evapotranspiration (ET) is a challenging task but an important research topic because both Q and ET play vital roles in the study of the hydrological cycle, of climate change, water resources, flood management and so on. In this paper we will present the modeling method to estimate the daily Q and ET for a medium-sized watershed in the tropical region of the North of Vietnam using the Soil and Water Assessment Tool (SWAT) and Bridging Event and Continuous Hydrological (BEACH) models. The models were calibrated and validated for the river discharge for SWAT and evaporation (E) for BEACH in a 12 year period from 2001 to 2012. The simulated ETs by the models were compared with the satellite-based ET of MODIS products. Our simulation results show that the SWAT and BEACH models are capable of satisfactorily reproducing (with the NSE > 0.62 and R2 > 0.78) the stream-gauged river discharge and the observed E, respectively. Daily ET varied from 0.3 to 14 mm day-1 and was highest from May to August and lowest from December to March. Although the monthly and yearly MODIS ETs were slightly higher than those of SWAT and BEACH, a strong relationship between them was found with a standard deviation ranging from three to 40 mm. A light decrease of ET values in the 12 years can be seen in the result analyses; however a longer simulation time might be needed to ensure this trend.

description: Manufacturing provides jobs and income that individuals, families, and communities in rural areas rely upon. In this study, rural manufacturing plant survival during a 15-year period (1996- 2011), which includes two recessions and a longstanding decline in manufacturing employment, is examined. An indepth survey, the 1996 ERS Rural Manufacturing Survey, is linked to quar - terly employment records so that the relationship between survival and plant- and community- level factors can be examined. Results suggest that smaller, independent manufacturing plants had higher survival rates than larger plants and multi-unit plants, such as branch plants. Results offer potential insights into rural economic development policy, like tradeoffs between retention incentives, financial capital access programs, or support for entrepreneurship development.

description: We use the thread model for linear chains of interacting monomers, and the ``polymer reference interaction site model'' (PRISM) formalism to determine the monomer-monomer pair correlation function $h_{mm}(r)$ for dilute and semi-dilute polymer solutions, over a range of temperatures from very high (where the chains behave as self-avoiding walks) to below the $θ$ temperature, where phase separation sets in. An inversion procedure, based on the HNC integral equation, is used to extract the effective pair potential between ``average'' monomers on different chains. An accurate relation between $h_{mm}(r)$, $h_{cc}(r)$ [the pair correlation function between the polymer centers of mass (c.m.)], and the intramolecular form factors is then used to determine $h_{cc}(r)$, and subsequently extract the effective c.m.-c.m. pair potential $v_{cc}(r)$ by a similar inversion procedure. $v_{cc}(r)$ depends on temperature and polymer concentration, and the predicted variations are in reasonable agreement with recent simulation data, except at very high temperatures, and below the $θ$ temperature.

description: We present a cosmological hydrodynamical simulation of a 10^13 Msun galaxy group and its environment (out to 10 times the virial radius) carried out using the EAGLE model of galaxy formation. Exploiting a novel technique to increase the resolution of the dark matter calculation independently of that of the gas, the simulation resolves dark matter haloes and subhaloes of mass 5x10^6 Msun . It is therefore useful for studying the abundance and properties of the haloes and subhaloes targeted in strong lensing tests of the cold dark matter model. We estimate the halo and subhalo mass functions and discuss how they are affected both by the inclusion of baryons in the simulation and by the environment. We find that the halo and subhalo mass functions have lower amplitude in the hydrodynamical simulation than in its dark matter only counterpart. This reflects the reduced growth of haloes in the hydrodynamical simulation due to the early loss of gas by reionisation and galactic winds and, additionally, in the case of subhaloes, disruption by enhanced tidal effects within the host halo due to the presence of a massive central galaxy. The distribution of haloes is highly anisotropic reflecting the filamentary character of mass accretion onto the cluster. As a result, there is significant variation in the number of structures with viewing direction. The median number of structures near the centre of the halo, when viewed in projection, is reduced by a factor of two when baryons are included.

description: We perform a study of the effect of the high in-plane electric field on the spin precession and spin dephasing due to the D'yakonov-Perel' mechanism in $n$-type GaAs (100) quantum wells by constructing and numerically solving the kinetic Bloch equations. We self-consistently include all of the scattering such as electron-phonon, electron-non-magnetic impurity as well as the electron-electron Coulomb scattering in our theory and systematically investigate how the spin precession and spin dephasing are affected by the high electric field under various conditions. The hot-electron distribution functions and the spin correlations are calculated rigorously in our theory. It is found that the D'yakonov-Perel' term in the electric field provides a non-vanishing effective magnetic field that alters the spin precession period. Moreover, spin dephasing is markedly affected by the electric field. The important contribution of the electron-electron scattering to the spin dephasing is also discussed.

description: Increasing global population and demand for food have led to rising agricultural production and demand for land; expanded agricultural land has often come from tropical deforestation. These forests support biodiverse ecosystems and further benefit the environment through carbon storage. This report analyzes patterns of deforestation in select countries to examine which commodities contribute most to “tropical” deforestation. ERS researchers use historical data on production and international trade patterns of four forest-risk commodities: palm oil, soybeans, beef, and forest products. Trade links for these commodities are quantified between the United States and six major exporting countries: Argentina, Brazil, Paraguay, Bolivia, Indonesia, and Malaysia. Deforestation in Argentina and Brazil is linked with production of beef and soybeans, while deforestation in Indonesia and Malaysia is linked with production of palm oil and timber. A global economic model is used to assess two potential policies that could affect tropical forest loss. Results indicate that removing tariffs on these forest-risk products could increase deforestation, while prohibiting exports of illegally logged wood could reduce deforestation.

description: Within many species, confusions occur between infraspecific taxa, recurrent ecotypic differentiation and phenotypic plasticity. Subspecies are often debated when they are supported only by slight morphological differentiation coupled to habitat variation. In this context we tested the evolutionary support of the four contested subspecies of Dianthus superbus. Based on 147 Eurasian accessions, our integrative study combines three complementary approaches: (i) Genetic differentiation, with neutral genetic markers, i.e. 326 AFLP markers, 25 nuclear microsatellites and nrDNA ITS ribotypes; (ii) morphological differentiation, with 20 morphometric characters measured in situ and ex situ to assess phenotypic variation; (iii) ecological differentiation, indirectly based on 128 floral volatile compounds under selection of habitat-specific pollinators. Phylogenetic, morphometric and biochemical analyses support the distinction between European and East Asian samples, with an intermediate position of Central Asian samples. However, in Europe, phylogenetic markers only slightly distinguish West from Central European samples, without support for subspecies. Morphometric differentiation was found for subsp. alpestris. This morphotype was stable ex situ under different climatic conditions, and also supported by slight differences in volatile scents and phenology. Infraspecific taxonomy still reveals interesting polymorphisms, but also calls for a revision toward refined taxa. Dianthus superbus subspecies highlighted three dissimilar cases: (i) the East Asian subsp. longicalycinus must be considered as a distinct species; (ii) the morphometric and ecological distinction of subsp. alpestris supports its ecotypic differentiation despite a lack of phylogenetic divergence; (iii) subsp. sylvestris was not supported by any markers, arguing for an artefact of phenotypic plasticity under different environmental conditions.

description: We used angle-resolved photoemission spectroscopy to study the shadow Fermi surface in one layer Bi2Sr1.6La0.4CuO6+delta and two layer (Bi,Pb)2Sr2CaCu2O8+delta. We find the shadow band to have the same peakwidth and dispersion as the main band. In addition, the shadow band/main band intensity ratio is found to be binding energy independent. Consequently, it is concluded that the shadow bands in Bi-based HTSC do not originate from antiferromagnetic interactions but have a structural origin.

Grain-Size Control on Petrographic Composition of Sediments: Compositional Regression and Rounded Zeros
Creators: name: Tolosana-Delgado, Raimon
name: Eynatten, Hilmar
Publisher: name: Springer-Verlag
Year: 2009

description: It is well-known that sediment composition strongly depends on grain size. A number of studies have tried to quantify this relationship focusing on the sand fraction, but only very limited data exists covering wider grain size ranges. Geologists have a clear conceptual model of the relation between grain size and sediment petrograpic composition, typically displayed in evolution diagrams. We chose a classical model covering grain sizes from fine gravel to clay, and distinguishing five types of grains (rock fragments, poly- and mono crystalline quartz, feldspar and mica/clay). A compositional linear process is fitted here to a digitized version of this model, by (i) applying classical regression to the set of all pairwise log-ratios of the 5-part composition against grain size, and (ii) looking for the compositions that best approximate the set of estimated parameters, one acting as slope and one as intercept. The method is useful even in the presence of several missing values. The linear fit suggests that the relative influence of the processes controlling the relationship between grain size and sediment composition is constant along most of the grain size spectrum.

description: Catalytic degradation of ciprofloxacin (CIP) was studied by using copper ferrite (CuFe2O4) nanoparticles coated on graphene oxide (CuFe2O4/GO) as a heterogeneous activator of peroxymonosulfate (PMS). CIP degradation efficiency by CuFe2O4/GO/PMS system was evaluated by affecting factors such as, pH of aqueous media, reaction time, different concentrations of PMS, various CIP and catalyst concentrations, trapping agents and water matrix inorganic components. Kinetic models of the catalytic oxidation process were also investigated. Also, based on quenching tests, a pathway of PMS activation and reactive species production in both solid and liquid phases was proposed. Results showed that under the optimum conditions (pH = 7, 2 mM PMS and 0.2 g/L catalyst), 98% of CIP (30 mg/L) and 45% of total organic carbon (TOC) were removed within 60 min. Pseudo-first-order kinetic model was the best fit with the experimental data of degradation process. The inhibiting effects of water inorganic species on CIP degradation were as follows: HCO3− >NO3− > Cl− > SO42-. CuFe2O4/GO remains active even after five cycles of reuse for CIP degradation and leaching of Fe and Cu metals in the solution was negligible. Transformation products of CIP by CuFe2O4/GO/PMS were analysed by GC-MS. Transformation products of CIP by CuFe2O4/GO/PMS were identified using GC-MS, and degradation pathways have been proposed. Investigating the free radicals showed that SO4•- radicals play an important role in the catalytic oxidative degradation process. CuFe2O4/GO in coupling with PMS can be utilised as an effective method to degrade/mineralise of antibiotics, due to the powerful catalytic activity, the generation of various free radicals, magnetically recyclable and the high stability and reusability potential.

According to Chirio & Lebreton (2007), this species of dry forests and wet savannahs is distributed in West and Central Africa. Additional collection would allow us to establish the distribution of the species inTogo. However, results obtained during the field work suggest that the occurrence of this species in ER I, III and IV is likely.

For a particularly interesting case with enhanced symmetry in which the lepton Dirac mass matrices are related to those in the quark sector, the CHOOZ angle is near the present limit and the CP violating phase relevant to thermal leptogenesis and to $ν0 ββ$ decay is near maximal.

description: This report uses a computable general equilibrium (CGE) model to explore the economic effects of a hypothetical 10-percent increase in foreign demand for U.S. agri - cultural exports. This demand shift was found to result in a 6.7-percent increase in the volume of such exports, worth $9.7 billion at 2013 prices, and a net increase in total U.S. employment (all economic sectors) of about 41,500 jobs—above and beyond the nearly 1.1 million full-time civilian jobs that U.S. agricultural exports currently support. Some 40 percent of these new jobs are created in rural (nonmetropolitan) counties. Most parts of the agri-food sector (i.e., production agriculture plus food and beverage manufac - turing) would see an increase in employment, while employment in other trade-exposed industries—most notably non-food-and-beverage manufacturing and mining—would decrease. The agri-food sector’s share of regional employment is the main determi - nant of the percentage change in total regional employment in our simulation. Since the agri-food sector accounts for a larger share of nonmetro employment than of metro employment, growth in U.S. agricultural exports is of greater relative importance to the economic prosperity of nonmetro communities.

description: We consider the problem of recovering the divergence-free velocity field ${\mathbf U}\in\mathbf{L}^2(Ω)$ of a given vorticity ${\mathbf F}=\mathrm{curl}\,{\mathbf U}$ on a bounded Lipschitz domain $Ω\subset\mathbb{R}^3$. To that end, we solve the "div-curl problem" for a given ${\mathbf F}\in{\mathbf H}^{-1}(Ω)$. The solution is expressed in terms of a vector potential (or stream function) ${\mathbf A}\in{\mathbf H}^1(Ω)$ such that ${\mathbf U}=\mathrm{curl}\,{\mathbf A}$. After discussing existence and uniqueness of solutions and associated vector potentials, we propose a well-posed construction for the stream function. A numerical method based on this construction is presented, and experiments confirm that the resulting approximations display higher regularity than those of another common approach.

description: The food system accounts for a large share of fossil fuel consumption in the United States, and energy accounts for a substantial and highly variable share of food costs. This intersection between food and energy markets suggests that public and private decisions affecting one market will have spillover effects in the other. For example, would increasing the share of population having diets that align with Federal dietary guidance reduce fossil fuel use in the U.S. food system? Would a carbon dioxide (CO 2 ) tax improve diet quality? To address these issues, we use the most recent data available to integrate the material-flows accounting framework adopted by the United Nations Statistical Commission into the existing food-system accounting structure of the ERS Food Dollar accounts. Then, we use mathematical optimization to model healthy diets. Our research indicates that U.S. agri-food industries are more sensitive to energy price changes than nonfood industries. We find that in 2007, fossil fuels linked to U.S. food consumption produced 13.6 percent of all fossil fuel CO 2 emissions economywide. Our study of alternative diets shows there are many ways to meet the Dietary Guidelines for Americans. If Americans made a minimal dietary shift to eat healthy, we find food-system energy use would decrease by 3 percent. By making greater changes from current consumption, we find food- system energy use could be reduced by as much as 74 percent. A tax on CO 2 emissions from fossil fuels would increase the cost of a typical meal by an average of 1.7 percent, with estimates ranging between 0.2 and 5.4 percent. ----- Errata: On March 8, 2017, ERS corrected a few errors made in the calculation of data reported in Figure 14 (p. 32) and in the calories columns in Table 5 (p. 34).

title: Exploring record-keeping and the use of micros in the nursery school and class
Creators: name: Moore, Elizabeth Frances
Publisher: name: The Open University
Year: 1988

description: The investigations which follow are exploratory in the sense that the topic is new and not that the methodology itself is innovatory. The new research topic relates to innovation in both in-service education and nursery practice with the starting point being that micro-based systems of database management and word-processing may contribute to nursery record-keeping in the 1990's. Such a micro-based system was introduced as part of an experimental intervention with a sample of classrooms. This could be seen as pre-feasibility work towards the development of an "expert system" to help nursery staff with future curriculum development, implementation, and record-keeping. The research question is: how might nursery record-keeping develop in the future, and in what conditions, and with what support? Factors associated with most successful outcomes in the experimental intervention were small nurseries, attendance of a full age-range of children, good quality curriculum, clearly differentiated staff roles, and prior record-keeping. (All classrooms were able to complete many procedures and were to some extent "successful".) A comparison was made of nursery records developed, by staff, during the micro experiment with those obtained from a national survey: there was a difference in that the micro-based records were more detailed. Analysis of individual participant responses also indicated that change in record-keeping practice took place during the intervention. A survey of the views of the experimental participants and a comparison group of nursery staff found that both groups expressed a willingness to work outside set hours to aid the introduction of micro-based record-keeping. However, the experimental group had given more thought to uses for micros in their classrooms. When the responses of nursery assistants and teachers were analysed separately, assistants were found to be less in favour of record-keeping and using micros in nurseries. Investigations, in the study as a whole, encompass a survey of under fives record-keeping throughout Britain and a detailed study of the keeping of official records in two contrasting LEA's. There are also critical reviews of relevant literature, the methods used for the investigations, and a final discussion of key themes.

description: In this work, a green hydrothermal method was utilised to synthesise NiO nanoparticles (NiO-NPs) as an effective and low cost adsorbent for dye adsorption from aqueous medium. The product was characterised using powder XRD, FTIR and SEM techniques and the adsorption behaviour of NiO-NPs was assessed using methyl orange (MO) dye. The maximum removal (97.56 mg/g) of MO onto NiO-NPs was observed at pH 4, adsorbent amount 0.03 g and temperature 40°C. Thence, on evaluating and optimising the factors affecting the adsorption, the results exhibited that 95% dye removal was reached in first 30 min, additionally the adsorption equilibrium, kinetics and thermodynamics models were investigated. The results showed that the adsorption followed Langmuir model and pseudo second order model. The thermodynamic assessment of adsorption of MO onto NiO-NPs indicated the feasibility, endothermic and spontaneous nature with enthalpy and entropy of the system being positive (∆H° = 8.661 KJ/mol, ∆S° = 7.310 J/mol K). Also, the order of magnitude of ∆G° and ∆H° revealed the reversibility of reaction that reflects the adsorbent could be regenerated and potential contender for dyes removal form textile wastes.

Aside from the ambient regional flow regime, the hydraulic conditions in an aquifer connected with a salt formation are determined by differences in salinity. Whereas density-driven flow patterns induced by the effect of salt have been studied before we focus on the additional effect of temperature. For the model setup, we select typical parameter values that are characteristic of not only the lowlands in Germany and Poland. For the computation of flow in a vertical cross-section, we use numerical modeling with COMSOL Multiphysics. The size and strength of eddies in the high salinity region above the aquifer base are strongly influenced by thermal effects. A sensitivity study shows a wide range of convection phenomena, ranging from the absence of convective motions via steady and oscillating circulation to unsteady fluctuating patterns. The flow and transport parameters show the highest sensitivity to the thermal Rayleigh number.

description: The combination of scanning electron microscope–cathodoluminescence (CL), fluid inclusion analysis and high-resolution electron probe microanalysis of Al, Ti, K and Fe in vein quartz has yielded results permitting a greater understanding of the complex mineralisation of the Central Oyu Tolgoi and Zesen Uul porphyry-style deposits, southern Mongolia. These data demonstrate the relationship between quartz precipitation, dissolution and ore deposition as the mineralising fluid chemistry changed through time. Four major quartz generations are identified in the A-type veins from the stockworks of both the Central Oyu Tolgoi (OTi to OTiv) and Zesen Uul deposits (ZUi to ZUiv). Despite differences in the associated alteration and mineralisation style, the observed CL textures and trace element signatures of the quartz generations are comparable between deposits. The OTi and ZUi stage formed both the primary network of A-type veins and pervasive silicification of the host rock. Using the Ti-in-quartz geothermometer, crystallisation temperatures for OTi and ZUi of between 598°C and 880°C are indicated. The main stage of sulphide mineralisation was accompanied by the dissolution of pre-existing quartz (OTi and ZUi) and precipitation of a weakly luminescent generation of quartz (OTii and ZUii) with a low Ti content, reflected in a calculated temperature drop from approximately 700°C to 340°C in Central Oyu Tolgoi and 445°C in Zesen Uul. OTii and ZUii stage quartzes show high and variable Al concentrations. The next stage of quartz in both deposits (OTiii and ZUiii) forms a fine network of veins in cracks formed in pre-existing quartz. OTiii and ZUiii quartz contain measurable fluid inclusions of moderate salinity (3–17.1 wt.% NaCl eq.), entrapped in the temperature range 256°C to 385°C. OTiii and ZUiii are not related to any sulphide mineralisation. The final OTiv and ZUiv stages are characterised by quartz–calcite micro-breccias that penetrate the A-type veins. Based on the calculated entrapment temperatures, the OTiv/ZUiv stage crystallised between 212°C and 335°C, and the quartz is characterised by elevated but variable Al and Fe contents. The CL and trace element signatures of the OTi to OTiii and ZUi to ZUiii stages of the two Mongolian porphyries show similar features to those observed in porphyry-style deposits from other regions. This suggests that a common sequence of quartz crystallisation occurs during the formation of early veins in many porphyry copper systems.

description: This study investigated the role of language in the frequency and nature of preschool children's memory strategies. Twenty children, aged 18-33 months, were observed during a memory-for-location task for their use of potentially strategic behaviors. Each child accompanied the researcher while she hid a stuffed toy in a natural location (e.g., under a pillow). The children were told to remember the toy's location, in order to retrieve the toy when a bell rang after a delay of 3 minutes. During the delay interval, six behaviors occurred: looking, pointing, approaching, attempting to retrieve, peeking, and verbalizations. These behaviors could be used by the child in order to aid their memory of the hiding place. A control trial was also included and was like the experimental trial in all respects except that the toy remained visible during the delay interval. Frequencies of the target behaviors were compared among themselves and also were correlated with scores on two standardized language measures. There were three main findings, (1) these young preschool children produced more of the target behaviors when memory was required than when it was not, (2) non-verbal strategies were used more often than verbal ones, and (3) verbal proficiency predicted the use of memory strategies. Post-hoc tests indicated that children who had more advanced language skills were less likely to use overt memory strategies but, as the task progressed, children who earned higher percentile scores on the language tests talked more during the experiment. These results are consistent with developmental theories that emphasize the initial cost of using memory strategies to solve a problem and the constraints inherent in low language knowledge. They also point to the importance of attending to non-verbal behaviors when evaluating cognitive skills in very young children.

description: We consider the equation of motion of a charged particle or a charged compact object in curved space-time, under the reaction of electromagnetic radiation and also consider a physical situation such that the charged particle or compact object emits gravitational radiation, thereby gravitational radiation reaction also acts on it. We investigate the effect of this metric perturbation i.e. the gravitational radiation on the electromagnetic self-force. We show that, besides the interaction terms derived by P. Zimmerman and E. Poisson (Phys. Rev. D 90, 084030, 2014), additional perturbative terms are generated, which are linear in metric perturbation and are generated due to perturbation of the electromagnetic self-force by the metric perturbation. We discuss the conditions of significance of these perturbative terms and also the interaction terms with respect to the gravitational self-force in various astrophysical and cosmological cases ; such as the motion of charged particles around black holes, some extreme mass-ratio inspirals (EMRIs) involving sufficiently accelerated motion of charged stars (specially neutron stars) or charged stellar mass black holes around supermassive black holes, and motion of charged particles around charged primordial black holes formed in the early Universe etc.. We find that in some astrophysical and cosmological cases these perturbative terms can have significant effect in comparison with the gravitational radiation-reaction term.

description: ERS’ Loss-Adjusted Food Availability (LAFA) data and Federal dietary intake surveys supply key data for monitoring Americans’ food and nutrient consumption. The LAFA data provide estimates for more than 200 food commodities back to 1970. The data are for the Nation as a whole and are not disaggregated by food source (at home and away from home). The dietary intake surveys, conducted by USDA’s Agricultural Research Service in conjunction with the National Center for Health Statistics, provide detailed data on food obtained and eaten by Americans at various locations. ARS has developed databases, in conjunction with ERS, to translate foods reported in dietary intake surveys into ERS food commodities. These databases enable ERS researchers to disaggregate LAFA availability data by demographics and by food source in this study. Consistent with ERS data indi - cating that the at-home market accounts for 58 percent of food expenditures and 68 percent of caloric intake, over half of all food commodities acquired over 1994-2008 were for at-home use. On average, over 80 percent of total fruits, dairy, and nuts—and 61 percent of all meats and fish—were acquired for at-home use. The at-home share of some commodi - ties (e.g., berries, fluid milk, caloric sweeteners, and nuts) rose over 1994-2008 while the share for others (e.g., chicken and wheat flour) declined.

description: Using data from three household surveys in Bangladesh, Ethiopia, and India, this report compares two commonly used measures of household food insecurity: a measure of caloric consumption (reported undernourishment) and an experiential measure. In the second measure, a single affirmative response to whether the house - hold experienced certain conditions or behaviors due to insufficient food designates a household as food-insecure (experiential-based measure). The authors demonstrate that a significant share of households categorized as undernourished because their caloric consumption is below 2,100 calories do not report experiencing any form of food insecurity. This finding is robust across different experiential food security metrics and different contexts. For India, which used a single indicator of experi - enced food insecurity, the experiential measure had the least overlap with the caloric consumption measure compared with the measure used in the other two country case studies. Although the measure from the Ethiopian survey, which contained nine expe - riential questions, had the most overlap with the caloric consumption measure of food insecurity compared with the measures used in India and Bangladesh, there was still substantial misclassification of food security status among households. These findings suggest that even if the overall prevalence of food security is similar when estimated with experiential and other measures of food security, experiential measures appear to be classifying a different subset of the population as food-insecure.
