Financial and Health Diaries 2012-2013: A year-long weekly panel of farming households in Nigeria and Kenya
No full textThe Financial and Health Diaries capture high-detail high-frequency data on how low-income households in developing countries manage money and make spending choices around healthcare. The data provide detailed weekly information on individuals’ financial activities, health events and interactions with healthcare providers
Bangladesh Agricultural Value Chain (AVC) Impact Evaluation: Baseline Survey
No full textFunded under the Feed the Future (FTF) Initiative, the Bangladesh Agricultural Value Chains (AVC) project being implemented by Development Alternatives International (DAI) is working to improve food (and nutrition) security through strengthened agricultural value chains.
The dataset comprises information gathered from a baseline survey of farmer households in rural districts in southern Bangladesh. The sample was composed of 1,000 households primarily growing a food crop (mung bean) and 1,000 household growing a non-food crop (jute). The survey collected information on: demographics; agricultural production and marketing; assets, expenditures and consumption, and women’s empowerment in agriculture.IFPRI1; Open Access;MTID
Cooperation in polygynous households
Full text linkEvidence that monogamous spouses often compromise household gains to maintain individual control over resources has informed the design of cash transfer schemes and other poverty alleviation programs. In polygynous households, decision making may be even less cooperative as co-wife conflict is common and welfare outcomes are often worse than in monogamous households, despite polygyny being associated with better ex ante prospects. Using a carefully designed series of two-person public goods games, we conduct a quantitative, ceteris paribus comparison of willingness to cooperate to maximize household gains across the two household types. We find that polygynous spouses and co-wives are less cooperative, one with another, than monogamous spouses. Co-wives are least cooperative toward each other and polygynous husbands are less cooperative with each of their wives than monogamous husbands are with their one wife. Finally, there are differences across the household types in the way husbands and wives condition their cooperativeness on how much they believe their spouses and co-wives will cooperate. Specifically, behavior in polygynous households is more reciprocal and apparently less altruistic than in monogamous households. This has implications for the design of poverty alleviation programs that transfer resources either in cash or in-kind.Non-PRIFPRI1; CRP2; E Building Resilience; G Cross-cutting gender theme; Capacity StrengtheningMTID; PIMCGIAR Research Program on Policies, Institutions, and Markets (PIM
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Intertemporal Choice and Income Regularity: Non-Fungibility in the Timing of Income Among Kenyan Farmers
No full textThe optimal design of informal contracts in agricultural value chains depends on when farmers prefer to be paid for their output. While the evidence from the time
preference experiments suggests a preference for early payments, ?eld studies often indicate that farmers will defer regular payments if given the opportunity. In this study, we explicitly test whether farmers are more patient regarding regular, earned income than regarding experimental windfall payments. We asked farmers in a dairy cooperative in Kenya to allocate both their milk income and a one-time gift between an early and a deferred payment date. We ?nd that a large majority of participants deferred their milk payments, while rarely choosing to defer the gift. Participants� survey responses suggest that we observe this di?erence because of mental accounting: participants earmarked their regular milk payments, but not the gift, to save for bulky expenditures. We conclude that deferred payments can provide value to producers by functioning as a savings device, even when decisions over windfall income suggest a preference for early payments. We are sharing the data collected through this experiment as well as our do-files for replication and further analysis purposes.CGIAR Research Program on Policies, Institutions, and Markets (PIM
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
