Assessing the dynamic impact of formal and perceived land rights on fruit tree cultivation: Exploring the moderating role of forest ecology, gender, and land acquisition method
No full textSecure land rights are essential for encouraging long-term agricultural investment, particularly in developing countries. Fruit trees, in turn, play a critical role in livelihoods due to their nutritional, economic, and environmental benefits. However, the specific effects of secure land tenure—measured through both formal and perceived land rights—on fruit tree cultivation in Ethiopia remain underexplored. In addition, there is limited understanding of how gender, local land use, and modes of land acquisition moderate this relationship. This study addresses these gaps using nationally representative panel data. The results show that secure land rights, whether formal or perceived, significantly promote fruit tree cultivation, both in terms of the number of trees and the likelihood of tree adoption on a plot. Notably, this impact strengthens over time. However, heterogeneity analysis reveals that the effect varies considerably depending on environmental and social factors, including local land use, gender, and land acquisition methods. Specifically, the study finds that the impact of secure land rights is more pronounced in communities located within forest ecosystems than in non-forest areas. These findings support the economic theory of property rights by demonstrating that secure land tenure fosters fruit tree cultivation, contributing to sustainable agriculture. The study underscores the importance of policies that enhance tenure security by reducing costs and expanding access to land certification. Moreover, addressing gender disparities through targeted interventions could empower women plot holders to exercise property rights more effectively, thereby boosting investment and improving economic outcomes in Ethiopia and similar settings

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
Political instability, corruption and inclusive growth in Ethiopia: Transmission channels and moderating roles
Get PDFThis paper examines the direct and moderating roles of political instability and corruption on inclusive growth in Ethiopia from 1992–2020. We also test whether corruption sands or greases the wheels of inclusive growth and whether the impacts of political instability and corruption vary across the low and high regimes of political instability. Different econometric approaches are applied to address these objectives, including simultaneous equation modelling, moderation analysis, and two-regime threshold regression. The findings robustly confirm negative impacts of political instability and corruption on inclusive growth. The effects of political instability and corruption are also channelled through investment and tourism and appear to be more severe in a higher political instability regime. Further, the study supports the ‘sanding the wheels’ hypothesis, which argues that corruption is harmful to economic activities. The results generally suggest that, unless proper efforts are taken to relieve the current political upheaval and ethnic conflicts in the country, the detrimental impacts of political instability and corruption will aggravate the country’s dire situation
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
The Role of Property Rights on Sustainable Forest and Agricultural Land Use in Ethiopia: Examining Historical, Contextual and Policy Perspective
Get PDFDispelling 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
