Última Epidemiological investigation on envenomation: from theory to practice J. Venom. Anim. Toxins incl. Trop. Dis. Chippaux,JP. A better understanding of the epidemiology of envenoming would improve care, provided that the survey is representative, reliable and accurate. Several types of surveys could help to clarify the incidence, severity, circumstances, factors and determinants of envenomations. The relevant information may be collected and analyzed from hospital records or case report forms (for retrospective studies) or established from a protocol of longitudinal observation of cases attended at health facilities during a given period (prospective study). The household survey includes interviewing all or part of the population of a locality with a standardized questionnaire to obtain information on the circumstances of the accident. Finally, standardized questionnaires can be... Tipo: Info:eu-repo/semantics/other Palavras-chave: Epidemiology; Snakebite; Methodology; Retrospective surveys; Prospective surveys; Household surveys. Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1678-91992012000400014 Does Measurement Error Explain a Paradox About Household Size and Food Demand? Evidence from Variation in Household Survey Methods AgEcon Gibson, John. Several recent papers report a puzzling pattern of food demand falling as household size rises at constant per capita expenditure, especially in poorer countries. This pattern is contrary to a widely used model of scale economics. This paper exploits within-country differences in household survey methods and interviewer practices to provide a measurement error interpretation of this puzzle. A comparison of household surveys in Cambodia and Indonesia with the results from Monte Carlo experiments suggest that food expenditure estimates from shorter, less detailed recall surveys have measurement errors that are correlated with household size. These correlated measurement errors contribute to the negative effect of household size on food demand and cause...

Ano: 1999 URL: http://purl.umn.edu/97524 Nontraditional Export Crops in Guatemala: Effects on Production, Income, and Nutrition AgEcon von Braun, Joachim; Hotchkiss, David; Immink, Maarten. Modernization of traditional agriculture entalls increased participation of the smallholder sector in the exchange economy. The achievement of this participation requires an open trade regime, domestic policies that ensure against market failures and public policy that effectively permits use of a new production technology for sustained growth. To open up these opportunities to small farmers, investment in rural intrastate is essential, as is investment in education that will enable these farmers to participate as entrepreneurs in the growth process must stimulate employment and increased returns to land. Nontraditional vegetables for export have a higher labor content and therefore promise to help foster rural modernization. In this study of...

Ano: 1989 URL: http://purl.umn.edu/42169 Farmer management of production risk on degraded lands: the role of wheat genetic diversity in Tigray Region, Ethiopia AgEcon Di Falco, Salvatore; Chavas, Jean-Paul; Smale, Melinda. This paper investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy. Drawing production data from household survey conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land degradation, and their interaction on the mean and the variance of wheat yield. Ethiopia is a centre of diversity for durum wheat and farmers manage complex variety mixtures on multiple plots. Econometric evidence shows that variety richness increases farm productivity. Variety richness also reduces yield variability but only for high levels of genetic diversity. Simulations with...

Ano: 2006 URL: http://purl.umn.edu/55417 Combining revealed and stated preference methods to assess the private value of agrobiodiversity in Hungarian home gardens AgEcon Birol, Ekin; Kontoleon, Andreas; Smale, Melinda. Hungarian home gardens are small-scale farms managed by farm households using traditional management practices and family labor. They generate private benefits for farmers by enhancing diet quality and providing food when costs of transacting in local markets are high. Home gardens also generate public benefits for society by supporting long-term productivity advances in agriculture. In this paper, we estimate the private value to farmers of agrobiodiversity in home gardens. Building on the approach presented in EPTD Discussion Paper 117 (2004), we combine a stated preference approach (a choice experiment model) and a revealed preference approach (a discrete-choice, farm household model). Both models are based on random utility theory. To combine the...

Ano: 2006 URL: http://purl.umn.edu/55415 Agricultural production in Greater Sekhukhune: the future for food security in a poverty node of South Africa? AgEcon Drimie, Scott; Germishuyse, T.; Rademeyer, L.; Schwabe, Craig. This paper argues that within the range of complementary activities necessary to secure the food security of marginalised groups in South Africa in places such as Greater Sekhukhune, the aspect of agricultural production is often neglected. A comprehensive approach to food security should focus on exploiting opportunities around increasing local food availability through production, as well as stimulating food accessibility by, for example, supporting small enterprises through micro-credit, and supporting food utilisation through education. In this way a range of options is created that vulnerable people can adopt to promote their livelihoods beyond survivalist strategies. This paper explores the issue of agricultural production within Greater Sekhukhune...

Ano: 2009 URL: http://purl.umn.edu/55045 Farm Productivity and Household Market Participation: Evidence from LSMS Data AgEcon Rios, Ana R.; Shively, Gerald E.; Masters, William A.. We analyze the correlation between farm productivity and market participation using comparable household data from Tanzania, Vietnam and Guatemala. Each farm’s input use and output levels provide a within-sample measure of relative productivity, which we relate to that household’s level of participation in local markets using a wide range of agricultural, demographic and infrastructural variables as controls and as instruments in two-stage regressions. Results indicate that, controlling for differences in market access and the underlying determinants of market participation, households with higher productivity have greater participation in agricultural markets. In contrast, households with greater rates of market participation do not consistently...

Ano: 2009 URL: http://purl.umn.edu/51031 THE ROAD TO PRO-POOR GROWTH IN ZAMBIA: PAST LESSONS AND FUTURE CHALLENGES AgEcon Thurlow, James; Wobst, Peter. Zambia is one of the poorest countries in Sub-Saharan Africa. Almost three-quarters of the population were considered poor at the start of the 1990s, with a vast majority of these people concentrated in rural and remote areas. This extreme poverty arose in spite of Zambia’s seemingly promising prospects following independence. To better understand the failure of growth and poverty-reduction this paper first considers the relationship between the structure of growth and Zambia’s evolving political economy. A strong urban-bias has shaped the country’s growth path leading to a economy both artificially and unsustainably distorted in favor of manufacturing and mining at the expense of rural areas. For agriculture it was the maize-bias of public policies that...

Ano: 2005 URL: http://purl.umn.edu/58383 Understand the energy demand behaviours for a sustainable management of the natural resources in Cameroon. AgEcon Nkendah, Robert. In order to fall under a prospect for sustainable management of the natural resources in Cameroon, this communication tries, using a 1996 survey carried out from 400 households in the towns of Yaounde, Mbalmayo and Ebolowa, to understand the demand behaviours of the urban households, with respect to the various sources of energy. The work aims to highlight the place of the firewood like source of energy. The results obtained confirm the important place of the firewood in its various forms like source of energy in urban areas and thus indicating a threat on the future of the natural resources, in particular forest, in Cameroon. The income-elasticity analysis showed that, contrary to "modern" fuels that are the oil and the gas which are normal goods, the...

Ano: 2007 URL: http://purl.umn.edu/7927 Income and Poverty Impacts of USAID-Funded Programs to Promote Maize, Horticulture, and Dairy Enterprises in Kenya, 2004-2010 AgEcon Smale, Melinda; Mathenge, Mary K.; Jayne, Thomas S.; Magalhaes, Eduardo Castelo; Olwande, John; Kirimi, Lilian; Kamau, Mercy W.; Githuku, James. Since 2002, the United States Agency for International Development (USAID) has funded programs to promote maize, dairy, and horticulture enterprises among smallholder farmers in Kenya under the Strategic Objective 7 of Increased Rural Household Incomes. On behalf of USAID, Tegemeo Institute has conducted household surveys to help track key indicators that monitor progress in the implementation of these programs. The first survey was conducted in 2004. Subsequent surveys were conducted every two years (i.e., 2006, 2008, and 2010). The sample comprises households participating and those not participating in the programs. The programs monitored include the Kenya Maize Development Program (KMDP), the Kenya Horticulture Development Project (KHDP), and the Kenya...

Ano: 2012 URL: http://purl.umn.edu/121864 Rural Household Access to Assets and Agrarian Institutions: A Cross Country Comparison AgEcon Zezza, Alberto; Winters, Paul C.; Davis, Benjamin; Carletto, Calogero; Covarrubias, Katia; Quinones, Esteban; Stamoulis, Kostas G.; Di Giuseppe, Stefania. Agriculture is at the core of the livelihoods of a large share of rural households throughout the developing world. Agricultural growth is a major engine for overall economic growth and possibly the single most important pathway out of poverty in the rural space. This paper characterizes household access to assets and agrarian institutions of households engaged in agricultural activities in a sample of developing countries. The evidence presented in the paper draws from 15 nationally representative household surveys from four regions of the developing world. We find that the access of rural households to a range of agricultural-specific assets (including land and livestock) and institutions is in general low, though highly heterogeneous across countries,...

Ano: 2007 URL: http://purl.umn.edu/7925 Who Should be Interviewed in Surveys of Household Income? AgEcon Fisher, Monica G.; Reimer, Jeffrey J.; Carr, Edward R.. This study tests the null hypothesis that it is sufficient to interview only the household head to obtain accurate information on household income. Results show that using a husband’s estimate of his wife’s income does not produce statistically reliable results for poverty analysis. Estimates of the wife’s income provided by the husband and wife are in agreement in only six percent of households. While limiting interviews to one person has the advantage of reducing the time and expense of household surveys, this appears detrimental in terms of accuracy, and may lead to incorrect conclusions on the determinants of poverty.
