Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Eremocaulon Soderstrom & Londono 1987
No full textEremocaulon Soderstrom & Londoño (1987: 37). TYPE:— Eremocaulon aureofimbriatum Soderstrom & Londoño (1987: 37). Plants cespitose. Culms homomorphic, erect below, arching and clambering above, often supported by trees, 2.5–20 m tall, infra- and supranodal bands of trichomes usually absent [present in E. capitatum (Trinius 1835: 626) Londoño in Londoño & Clark (2002: 714)]. Branch complement with one dominant and smaller secondary branches, without thorns. Culm leaves and foliage leaves clearly distinct. Culm leaves not clearly differentiated along the culm, with reflexed blades, narrower than the sheath summit, sheath fimbriae present. Foliage leaf sheaths with fimbriae at the apex or not, translucent swelling absent, outer ligule present, blades narrowly triangular, ovate-lanceolate or linear-lanceolate, midnerve prominent. Synflorescences terminal to leafy, indeterminate, 1–15 pseudospikelets per coflorescence, coflorescences either with one to few pseudospikelets and open or with several to many pseudospikelets and congested to capitate, each coflorescence and paraclade or pseudospikelet with one subtending bract; pseudospikelets sessile, bisexual, glumes absent, comprising 1 prophyll, 0–4 gemmiparous bracts, with 1–17 fertile anthecium, smooth, and with 1–4 terminal rudimentary anthecium. Fruit a basic caryopsis, hilum linear, as long as the caryopsis. Eremocaulon is a woody bamboo genus endemic to Brazil (Londoño & Clark 2002, Kellogg 2015, Jesus-Costa et al. 2018). It is characterized by its branch complement with one dominant and smaller secondary branches, without thorns, infra- and supranodal bands of trichomes absent (present in E. capitatum), culm leaves with reflexed blades, narrower than the sheath, foliage leaves with midnerve prominent and synflorescences composed of pseudospikelets (Londoño & Clark 2002). The genus has five species in the Amazon, Cerrado and Mata Atlântica domains (Lopes-Neto et al. 2020). In the Serra do Cachimbo, the genus is represented by one species.Published as part of Lopes-Neto, Raimundo Balieiro & Viana, Pedro Lage, 2022, Flora of the Serra do Cachimbo (Eastern Amazon, Brazil): Bambusoideae (Poaceae), including the description of two new species, pp. 99-129 in Phytotaxa 550 (2) on page 107, DOI: 10.11646/phytotaxa.550.2.2, http://zenodo.org/record/664108
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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 textThis 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

Resistencia a la compresión paralela a la fibra de una especie de bambú nativo de México (Otatea fimbriata Soderstrom)
No full textEn la presente investigación se determinó el esfuerzo máximo a la compresión paralela a la fibra en una especie de bambú nativo de México (Otatea fimbriata Soderstrom), encontrada de forma silvestre en el municipio de Suchiapa, Chiapas, para su validación como material de construcción. Se ensayaron muestras con nudo y sin nudo de la parte inferior, media y superior de los culmos, siguiendo los procedimientos de la NTC-5525:2007 “Métodos de ensayo para determinar las propiedades físicas y mecánicas de la Guadua Angustifolia Kunth” y las Normas ISO: 22157-1: 2004 e ISO TR 22157-2: 2004. Los valores de resistencia máxima están dentro del rango reportado de otras especies de bambú (genero Guadua). Los valores a compresión demuestran que la Otatea fimbriata Soderstrom es un material alternativo, natural, altamente renovable y con alto potencial para su uso en construcción
Mining e-mail content for author identification forensics
No full textWe describe an investigation into e-mail content mining for author identification, or authorship attribution, for the purpose of forensic investigation. We focus our discussion on the ability to discriminate between authors for the case of both aggregated e-mail topics as well as across different email topics. An extended set of e-mail document features including structural characteristics and linguistic patterns were derived and, together with a Support Vector Machine learning algorithm, were used for mining the e-mail content. Experiments using a number of e-mail documents generated by different authors on a set of topics gave promising results for both aggregated and multi-topic author categorisation
