World Social Report 2021: Reconsidering rural development
No full textAn urgent reconsideration of rural development is needed for achieving the 2030 Agenda for Sustainable Development. The current strategies and patterns of rural development are failing to meet either the socioeconomic or the environmental Goals of this Agenda. Four out of every five people who face extreme poverty around the world live in rural areas. Many rural areas are witnessing severe depletion and degradation of natural resources, contributing to climate change and the recurrence of zoonotic diseases, such as COVID-19.
The COVID-19 pandemic, together with already persistent high levels of poverty and inequalities, are threatening to stall progress for the world’s rural populations. Through response and recovery efforts, however, opportunities exist to build a greener, more inclusive and resilient future. The experience of the pandemic has shown, for example, that where high-quality Internet connectivity is coupled with flexible working arrangements, many jobs that were traditionally considered to be urban can be performed in rural areas too.
The World Social Report 2021, a flagship publication of the United Nations Department of Economic and Social Affairs (UN DESA) on major social development issues offers new strategies to ensure that the 3.4 billion people who live in rural areas are not left behind as global efforts focus on boosting socio-economic growth and tackling climate change in the middle of the COVID-19 recovery.
The report calls for an end to the rural-urban divide and offers new approaches to advance rural development that would allow rural populations to reach the urban standard of living without having to migrate to urban areas. These include leveraging the rise of new digital technologies, boosting the non-farm economy and increasing investments in public services and rural infrastructure while protecting the health of the planet.Non-PRIFPRI5; 1 Fostering Climate-Resilient and Sustainable Food Supply; CRP5EPTD; DGOCGIAR Research Program on Water, Land and Ecosystems (WLE
Information and communication technology for agriculture in the People’s Republic of China
No full textThis report presents the findings of an assessment on the use of information and communication technology (ICT) to improve food production and distribution in the People’s Republic of China. The analysis focuses on e-commerce in rural areas of the country and provides policy recommendations to promote the use of ICT in the agricultural supply chain. The report documents the trends in ICT application by farmers and its impact on income and livelihood. It also identifies the major constraints to and enabling factors for such ICT applications.Non-PRIFPRI2; CRP2EPTD; PIMCGIAR Research Program on Policies, Institutions, and Markets (PIM
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
