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

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
Power balancing in STS group cranes with flywheel energy storage based on DSM strategy
No full textConsidering the highest power demand by Ship to Shore (STS) cranes in pier E at the port of Long Beach, designing a proper control system can harness the peak load increasing. In this paper, tw o strategies have been used for the peak load shaving. First, demand side management (DSM) in order to peak power demand minimization by duty cycle coordination between STS cranes based on PSO algorithm and in the second part utilization of Flywheel Energy Storage System (FESS) to make a power balance between generation and demand side. Results in MATLAB related to reference data shows the proposed method can reduce the peak power demand in the STS group cranes and provide a proper power balance between generation and demand
Optimization of peak load shaving in STS group cranes based on PSO algorithm
No full textMost of the power demand at Container Terminals (CT) is related to Ship to Shore (STS) cranes. These cranes work simultaneously together for loading and unloading container. This issue causes the peak demand increase significantly. Considering the STS group crane's activity to move containers (from ship to shore and vice versa), finding the best delay time between STS cranes can play an important role to reduce the total power demand. The peak shaving strategy which has been used in this paper is Demand Side Management (DSM). DSM method increases e\square cient energy utilization and power quality of the system as well as the peak power and energy costs reduction. Simulations have been made for a preliminary evaluation of prospected efficiency goals. Results in MATLAB related to reference data shows the proposed method can reduce the peak power demand in STS group cranes around 60-70%. The simulations confirm also that the evaluation of the peak shaving assuming an equal time delay in the cranes duty offers acceptable preliminary estimates and reassures a simpler management
Ultracapacitors for port crane applications: Sizing and techno-economic analysis
No full textThe use of energy storage with high power density and fast response time at container terminals (CTs) with a power demand of tens of megawatts is one of the most critical factors for peak reduction and economic benefits. Peak shaving can balance the load demand and facilitate the participation of small power units in generation based on renewable energies. Therefore, in this paper, the economic efficiency of peak demand reduction in ship to shore (STS) cranes based on the ultracapacitor (UC) energy storage sizing has been investigated. The results show the UC energy storage significantly reduce the peak demand, increasing the load factor, load leveling, and most importantly, an outstanding reduction in power and energy cost. In fact, the suggested approach is the start point to improve reliability and reduce peak demand energy consumption
Utilization of Regenerative Energy by Ultracapacitor Sizing for Peak Shaving in STS Crane
No full textThis paper presents a strategy to avoid peak demand rising and energy management due to existing cranes at container terminals (CT). The new generation of the Ship to Shore (STS) cranes installed at the port of Long Beach (POLB) are equipped with the capabilities to absorb up to 90% of the regenerative energy (RE). Hence, a percent of RE is fed into the dc-bus in an STS Crane and deliver to the Ultracapacitor (UC) bank energy storage system (ESS). As an effective method, UC sizing is able to do the local peak shaving in each STS Crane and then with the remaining percent of the RE by the duty cycle coordination for the STS group Cranes the overall peak power minimization in point of delivery has been reviewed based on PSO algorithm. Results in MATLAB shows the two proposed methods can reduce the peak power demand and increase the percentage of the utilization energy factor (UEF) in STS cranes
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
