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
DATA CASSIFICATION AND INFORMATION LIFECYCLE MANAGEMENT IN PORT COMMUNITY SYSTEMS
Full text linkRad istražuje ulogu klasifikacije podataka (Data Classification) i upravljanja životnim ciklusom informacija (Information Lifecycle Management) u objedinjenim sustavima informatičko-telekomunikacijske razmjene podataka i poruka u lučkom okruženju (Port Community Systems). U radu se analiziraju problemi koji nastaju prilikom implementacije takvih sustava, a uzrokovani su kompleksnošću pojedinih informacijskih i organizacijskih sustava sudionika u procesu. Predlaže se nekoliko modela klasifikacije podataka, izvedenih iz standardne metodologije sigurnosti informacijskih sustava. Identificiraju se ključni elementi potrebni za uvođenja sustava za klasifikaciju podataka i upravljanje životnim ciklusom informacija te se predlažu implementacijski putovi kojima bi se prebrodile moguće poteškoće u funkcioniranju sustava.The purpose of this paper is to research the role of the Data Classification (DC) and Information Lifecycle Management (ILM) processes in Port Community Systems (PCS). Issues that are likely to be encountered in the implementation of such systems are defined by the complexity of the PCS stakeholders' own ICT and organizational systems and are therefore clearly outlined. Furthermore, several data classification models are proposed, which are derived from the standard methodology of information systems security. The paper identifies possible key issues during the DC/ILM system implementation and finally proposes suggested implementation paths in order to overcome operational difficulties
Analyzing of micro-electro-mechanical systems (MEMS) sensor for pumping aggregates
No full text
Purpose
The purpose of this research paper is to develop and analyze micro-electro-mechanical systems sensor for vibration monitoring of pumping aggregate.
Design/methodology/approach
The system is based on smart sensor and smart mobile phone.
Findings
The numerous measurements on a wide range of turbo aggregates were performed to establish the operating condition of pumping aggregates.
Originality/value
Afterwards, the influence of vibration at different positions on the output vibration of the pumping aggregate was analyzed by adaptive neuro fuzzy inference system method.

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
