    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    Author, publisher and bookseller : a tripartite synergy in Nigerian book industry

    No full text
    This work is about the roles of Author, Publisher and Bookseller in Book development in Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after which it proceeded by defining who an author, a publisher, and a bookseller is and expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in the emerging Information Society. Furthermore, the various constraints to book development were identified while the paper advised on how the Book Industry can be further promoted in Nigeria. However, the paper concluded and made recommendations on how the Book sector can help in enhancing scholarship in the country

    Fighting for justice and freedom through music: The case of Thomas Mapfumo, Hosiah Chipanga and Leonard Zhakata, ca. 1988–2015

    The pervasive contention in scholarship on contemporary Zimbabwe is that the quintessence of the post-independence Zimbabwean experience consists in unchecked political dictatorship and unprecedented economic regression. This contention derives from the fact that with the advent of independence in 1980, the Zimbabwe African National Union-Patriotic Front (ZANU-PF) regime that replaced the Rhodesia Front (RF) in the corridors of power embarked on a campaign to achieve political hegemony through the entrenchment of patronage, violence and corruption. However, this is not all that there is to the post-independence Zimbabwean narrative. As this article makes clear, the post-independence Zimbabwean experience also speaks to a pro-democracy struggle in which the authors of the Zimbabwean debacle are confronted on various platforms, particularly the protest songs of musicians such as Thomas Mapfumo, Hosiah Chipanga and Leonard Zhakata. Since the late 1980s, these musicians have been relentless in their criticism of the ZANU-PF establishment, its strong-arm tactics and self-image as the indispensable guardian of Zimbabwean interests. This article maintains that through euphemism, ridicule and overt criticism, Mapfumo, Chipanga and Zhakata forge an aesthetic of resistance that exposes and contests the institutionalisation of patronage, violence and corruption in post-independence Zimbabwe

    Stochastic simulation of soil water status on reclaimed land in northern Alberta

    Studies of spatial variability and simulation of available soil water and extractable soil water are scarce and yet such data are essential in hydrologic and solute transport modeling. A study was conducted to characterize spatial variability of available soil water and extractable soil water on a reclaimed site in northern Alberta. The vegetation on site included grasses, legumes and shrubs. The site was reclaimed and the reconstructed profile was made up of 40-100 cm of clay loam/peat material overlying fine tailings sand. Soil water was measured using neutron moisture meters on a frequency of approximately two weeks during the growing season for a 2-year period. Spatial characterizations of available soil water (ASW) and extractable soil water (ESW) on the driest and wettest measurement days were conducted using geostatistical methods. A sample semi-variogram was estimated and several permissible theoretical models fitted and the model of best fit was determined using the Akaike Information Criterion (AIC). The spherical model was found to best represent the semi-variogram for available soil water and extractable soil water. Both the available soil water and extractable soil water had very high degrees of spatial dependence (> 99%) and the range of within which sample points were auto-correlated was less than 1 m. The conditional stochastic simulation of extractable soil water at unsampled locations that were 5 m north of the sampled locations indicated a high degree of uncertainty. This implies that generation of exhaustive data sets may require more sampling points at closer spacing to reduce uncertainty

    Antecedent soil water for managed landscapes in central Alberta

    Land management practices are known to influence runoff through alteration of the antecedent soil water For accurate estimation of runoff, direct measurement of antecedent soil water would be necessary. This study investigated antecedent soil water and the potential for summer storm runoff under different land management practices. The two-year study was conducted on five sires: three sites under forage (one on reclaimed mine lands), and two sites under pasture. Treatments included haying, mowing, fallow, and moderate and heavy livestock grazing. Soil water was measured with a neutron probe and was generally less than 50% of water holding capacity (dry conditions). During recharge periods, water increased to nearfield capacity, but soil water was close to wilting point for some measurement dates. Pasture sites were generally wetter than forage sites, with the difference being most pronounced on fallow treatments. The reclaimed site had generally lower total soil water than the unmined ones
