Willingness-to-Pay for a Small Quantity Lipid-Based Nutrient Supplement by Mothers of Young Infants in Malawi
Get PDFSmall-quantity lipid-based nutrient supplements (LNS-SQ) are designed to prevent undernutrition amongst vulnerable populations including pregnant and lactating women and infants 6 to 24 months of age. The objective of this study was to estimate the willingness-to-pay (WTP) of mothers in Malawi for a LNS-SQ product for infants, and to explore the factors influencing their valuation of the product. To accomplish this, a double-bounded contingent valuation survey was conducted in November and December 2016 with 504 mothers of infants aged 6 to 36 months old in the Zomba region of Malawi. 77% of respondents indicated a positive WTP for the product. Mean WTP based on maximum likelihood estimation was 112 MWK, equivalent to approximately 0.15 USD or 0.21 CAD. These findings have implications for the pricing and distribution of LNS-SQ through retail channels in Malawi

Chapter 1 reviews the existing evidence regarding the impact of livestock interventions, drawing primarily from the literature on livestock transfer programs, graduation programs, and livestock insurance. Livestock contribute to the welfare of rural poor households in many ways. Livestock products can be consumed, utilized, or sold for income. If consumed, livestock facilitate improved food security and nutrition. Income from livestock sales can be used for consumption – indirectly contributing to food security and nutrition – or invested. In the absence of developed financial markets, livestock also provide a savings mechanism, potentially enhancing resilience. Livestock ownership can be particularly important for rural women. Although livestock interventions have the potential to improve child nutrition outcomes, livestock intensification may pose risks related to water, sanitation and hygiene (WASH) conditions. Chapter 2 assesses the impact of SELEVER, a nutrition- and gender-sensitive poultry intervention, with and without added WASH focus, on hygiene practices, morbidity and anthropometric indices of nutrition in children aged 2-4y in Burkina Faso. We implement a 3-year cluster randomized controlled trial in 120 villages in 60 communes (districts) supported by the SELEVER project. Communes were randomly assigned using restricted randomisation to one of three groups: (1) SELEVER intervention (n=446 households); (2) SELEVER plus WASH intervention (n=432 households); and (3) control without intervention (n=899 households). Our study population included women aged 15-49y with an index child aged 2-4y. We assess effects 1.5y (WASH sub-study) and 3y (endline) post-intervention on child morbidity and child anthropometry outcomes. Participation in intervention activities was low in the SELEVER groups, ranging from 25% at 1.5y and 10% at endline. At endline, households in the SELEVER groups had higher caregivers knowledge on WASH-livestock risks and were more likely to keep children separated from poultry than in the control group. No differences were found for other hygiene practices, child morbidity symptoms or anthropometry indicators. Integrating livestock WASH interventions alongside poultry and nutrition interventions can increase knowledge of livestock-related risks and improve livestock-hygiene related practices, yet may not be sufficient to improve morbidity and nutritional status of young children. Chapter 3 explores the impact of a cash+ program in Malawi on lean season food security. Rural households in sub-Saharan Africa face high levels of poverty and annually recurring periods of lean season food insecurity. We conduct a randomized controlled trial in rural Malawi to assess the impact of coupling unconditional cash transfers of either 43/month with a nutrition behavior change intervention on the diets and food security of households during the lean season. We find evidence of protective effects, but only when the intensity of treatment is high. When combined with the behavior change intervention, the large monthly cash transfer of 43/month invested in agricultural inputs and assets, allowing them to produce and store more maize in the preceding harvest and partially insulating them against negative food price shocks. We do not find evidence of similar effects of the nutrition behavior change intervention alone or in conjunction with a smaller transfer of $17/month
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
