No full textFood availability, entitlements and the Chinese famine of 1959-61
No full textFood availability decline and Sen's entitlement are two leading approaches in understanding causes of famine. Previous research based on case studies has given independent support to each approach. This paper analyses the Chinese famine of 1959-61 by considering;jointly the urban bias and the decline in food availability as causes. We find that both factors contributed significantly to the increase in death rates during this famine. To our knowledge, this paper is the first econometric study to assess the importance of famine causes using the entitlement approach.EconomicsSSCI46ARTICLE460136-15811

No full textEDUCATION AND INNOVATION ADOPTION IN AGRICULTURE - EVIDENCE FROM HYBRID RICE IN CHINA
No full textThis paper uses the diffusion of F1 hybrid rice as a case for examining the effects of education on the adoption of new technology in China. A simple behavioral model that treats the adoption of hybrid rice as a portfolio selection problem is presented. The implications of the model are tested with farm-level data collected from a sample of 500 households in Hunan Province. The results from a dichotomous probit model and a two-limit tobit model are consistent with the hypothesis that education has a positive impact on the adoption of new technology.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1991GB73400015&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Agricultural Economics & PolicyEconomicsSCI(E)SSCI48ARTICLE3713-7217
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
