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

No full textDispelling 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
A MICRO-LEVEL VIEW OF LOW-INCOME RURAL HOUSING IN BANGLADESH
Full text linkAlthough the majority of the population of the developing world is rural, compared to urban
housing there is less emphasis on rural housing in current literature. Bangladesh is a case in point,
with its nearly 80% rural population with a low-income majority. Various agencies there attempt
to address rural housing problems; in addition to government programmes, there is now an
expanding network of NGO-based rural development programmes, including housing. This
presents low-income households with a changing scenario within which their efforts to build
housing operate. Agency-based housing efforts lack the benefit of rigorous research, especially
one that reflects perceptions at the micro-level, primarily of low-income rural communities. This
study addresses the need for in-depth and investigative research of strategies for dealing with
housing problems of low-income rural communities, both by agencies and low-income
households.
The principal thrust of the research is empirical. Agency projects representing a wide range of
strategies and programme types were selected as case studies to study beneficiaries and other
households in each project location. In-depth information was gathered from diverse low-income
households in different geographical locations in Bangladesh, as well as from operational staff of
agencies and other related persons. Literature review and background experience indicates that the
housing process has three main aspects: financing, implementation and housing design. Data
collection and analysis were conducted according to these aspects.
Despite various agency efforts to finance low-income rural housing, it was found that the poorest
households generally tend to be excluded; among households funding their own housing, the rural
majority, the poor face severe financial constraints. Implementation of housing programmes was
studied mainly according to the level of household participation. Corruption was found a typical
feature in many agency projects, often because of the limited nature of household participation;
self-built housing usually proves advantageous to households, but is also affected by the
permeation of the cash-economy. Agency-planned settlements are often not well-designed, but
self-organised sites, despite meeting many local needs, face problems of infrastructure, tenure
security and building material supply. Some durable types of construction, using manufactured
materials, promoted by some agencies, have become popular, but most are unaffordable to the
poor and face contextual problems. One the other hand, supply of less expensive natural materials
is becoming tenuous because of increasing depletion of the natural resource base.
Analysis of empirical findings indicates some advantageous concepts, but in general the findings
imply scope for improved policy and practice. 1b.is study allows for drawing out such implications
for the financing, implementation and housing design of future low-income rural housing
programmes
