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
Joint Transmitter-Receiver Design in TDD Multiuser MIMO Systems: An Egocentric/Altruistic Optimization Approach
No full textThis contribution considers joint transmitter-receiver design in general multiuser multiple-input multiple-output (MIMO) systems, where uplink and downlink use time-division duplex (TDD). We assume that there exist multiuser interference as well as other jamming signals in the system. The optimization strategy considered in this contribution represents one of the applications of the theory proposed in \cite{Lie-Liang-transmitter-receiver-VTC07-B}, where the transmitters and receivers are respectively optimized in order to achieve their altruistic (O)-optimum and egocentric (E)-optimum solutions. Furthermore, a novel criterion of minimum power distortionless response (MPDR) is proposed for transmitter preprocessing. Our design motivates simple mobile terminals (MTs) with low-complexity. Our study and performance results show that the MPDR-assisted transmitter preprocessing is capable of efficiently suppressing the multiuser interference. However, joint transmitter-receiver optimization is required, in order to suppress the extra jamming signals

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

No full textSince more and more mobile applications are based on the proliferation of social information, the study of Mobile Social Net-works (MSNs) combines social sciences and wireless communications. Operating wireless networks more efficiently by exploiting social relationships between MSN users is an appealing but challenging option for network operators. An MSN-aided content dissemination technique is presented as a potential ex-tension of conventional cellular wireless net-works in order to satisfy growing data traffic. By allowing the MSN users to create a self-organized ad hoc network for spontaneously disseminating contents, the network operator may be able to reduce the operational costs and simultaneously achieve an improved network performance. In this paper, we first summarize the basic features of the MSN architecture, followed by a survey of the factors which may affect MSN-aided content dissemination. Using a case study, we demonstrate that one can save resources of the Base Station (BS) while substantially lowering content dissemination delay. Finally, other potential applications of MSN-aided content dissemination are introduced, and a range of future challenges are summarized
