Food for the Footloose: An Analysis of the Mukhyamantri Dal Bhat Yojana in Jharkhand
Get PDFThere is a large and growing mobile, unsettled, kitchenless population ‘out there’ which lacks food and nutrition security. Most of them belong to the unorganised sector and many of them face extremely harsh living and working conditions. This footloose population is largely excluded from most social security interventions. Many of them, particularly migrant workers, do not possess documents which enable them to purchase grain from the subsidised public distribution system. They also suffer from much higher rates of undernutrition than the settled populations. However, despite the obvious threat of hunger and food insecurity among the footloose, the subject has largely remained ignored like a blind spot in the academic and policy discourse on hunger, food security and urbanisation.
Policies to set up and operate canteens providing subsidised cooked meals offer a solution for the food and nutrition insecurity faced by the urban poor footloose. However, their precise role and performance has not been studied or understood.
This study of the Mukhyamantri Dal Bhat Yojana in Ranchi city of Jharkhand, therefore, is expected to help to understand the role of a state sponsored subsidised meal programme in addressing food insecurity of the urban footloose poor. Through a comprehensive analysis of the programme, it attempts to understand the performance of the policy as well as understand factors which drive its performance
Does Greater Autonomy among Women Provide the Key to Better Child Nutrition?
Get PDFWe examine the link between a mother's autonomy – the freedom and ability to think, express, act and make decisions independently – and the nutritional status of her children. We design a novel statistical framework that accounts for cultural and traditional environment, to create a measure of maternal autonomy, a concept that has rarely been examined previously as a factor in children's nutritional outcomes. Using data from the Third Round of the National Family Health Survey for India, supplemented with our qualitative survey, and accounting for "son preference" by limiting analysis to first-born children under 18 months of age, we document that maternal autonomy has a positive impact on the long-term nutritional status of rural children. We find that one standard deviation increase in maternal autonomy score (i) is associated with a 10 percent reduction (representing 300,000 children) in the prevalence of stunting, and (ii) compensates for half of the estimated average decline in Height-for-Age Z-scores Indian children experience in the second six months of life. The findings underscore the importance of women's empowerment in improving children's nutrition during the critical first two years of life, a recognized "window of opportunity" for lifelong health and economic benefits
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
Lockdown, demonetisation to CAA, farm laws: How hasty policies have killed Indians
No full textThe landmark American movie 12 Angry Men, released in 1957, holds an important lesson for contemporary India. It is an intense courtroom drama in which the fate of a young man charged with murdering his father depends on the verdict of a 12-member jury. As per the judge’s instructions, if there was any reasonable doubt that the accused may not have committed the crime, the jury must pronounce him not guilty
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
