India's demographic and food prospects: state level analysis
No full textThis paper is a state-level analysis of India's demographic and food prospects. The first part of the paper that contains new population projections argues that future demographic growth will probably be a little less than estimated although the country's population will still go on to exceed 1.5 billion. The second part of the paper assesses the future demand for cereals and other foods in 2020 and concludes that the real production challenge relates to vegetables, fruit and milk
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

Full text linkImportance:Current cancer screening guidelines recommend cessation of cervical cancer screening at age 65 for most women. To examine residual risk among elderly women, we compared cervical cancer incidence rates in Massachusetts from 2004\u20132015 among women aged <65 vs. 6565.Methods:The Massachusetts Cancer Registry (MCR) was used to identify all women diagnosed with cervical cancer between 1/1/2004\u201312/31/2015. Cancer incidence was calculated based on age of diagnosis (<65 vs. 6565).Results:In Massachusetts, 2,418 incident cases of cervical cancer were diagnosed from 2004\u20132014, of which 571 (23.6%) were diagnosed among women ages 65 and older. When compared with women diagnosed under age 65, women diagnosed at age 6565 were more likely to be diagnosed with Stage II or higher (71.8% vs. 43.8%, p < 0.001). Cervical cancer incidence rates decreased annually for women <65 from 2004\u20132015. Among women aged 6565, cancer incidence rates decreased by 3.9% annually from 2004\u20132013 (p=0.0009), but 2013\u20132015 showed an increasing trend (APC + 14.1%, p=0.12).Conclusions and Relevance:Women 65 and over account for one quarter of cervical cancer diagnoses in Massachusetts, and present with higher stage disease than younger women. Upcoming planned revisions in screening and prevention guidelines should address the continued risk of cervical cancer for older women.T32 CA009001/CA/NCI NIH HHSUnited States/UM1 CA221940/CA/NCI NIH HHSUnited States/R25 CA098566/CA/NCI NIH HHSUnited States/T32 ES007069/ES/NIEHS NIH HHSUnited States/T42 OH008416/OH/NIOSH CDC HHSUnited States
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
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
