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
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

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

Abstract
This study examines the vulnerability, adaptation, and resilience of urban poor households living in the riverine communities of the three flood prone areas in Metro Manila, namely, (1) Pasig-Marikina River basin, (2) West Mangahan, and (3) the KAMANAVA area (Kalookan, Malabon, Navotas, Valenzuela). Based on a survey of 300 urban poor households in 14 communities located in these flood basins, the study found that the environmental-ecological vulnerability of the low-lying flood prone areas interacts strongly with the social vulnerability of urban poor households, highlighting the effects of climate related changes (sea level rise, increased typhoons, intensity of monsoon rains, floods and tidal/storm surges) on this vulnerable population.
Most of the households have low-incomes, live in slum/squatter settlements and do not have adequate access to potable water, electricity, health, sewage and sanitation facilities. About two-thirds of them suffered losses (e.g., income, work, health/sickness, household appliances/things, housing damage) from typhoons, floods, and tidal/storm surges but only a small portion of them obtained help from formal institutions (e.g., local government units or LGUs, charitable agencies) and informal support networks (relatives/neighbors/friends). Of these, a third of these households appeared more vulnerable and consistently incurred higher losses (e.g., income and workdays) and intense inconveniences (e.g., water source buried by floods, toilets blocked and overflowed with wastes/large worms to their floors) compared to their neighbors.
Both urban poor households and their local governments have formulated adaptation strategies in response to the increasing effects of climate change. Few of the local governments built river barriers, improved their drainage systems, installed water diversion techniques (e.g., “bombastic”) and disaster warning systems and increased the capacity of their officials to assist during evacuations. Meanwhile, some urban poor households have adapted to a “water-based lifestyle” (e.g., raising the floors/increasing the number of floors of their homes, building makeshift bridges among households in swampy areas, building Styrofoam boats for transport, etc.). But on the whole, both the urban poor residents and the formal institutions (LGUs, national agencies) need resources and capability building to increase their capacity to adapt to the effects of climate change.
