Two-phase optimized experimental design for fatigue limit testing
No full textThis study proposes an innovative Two-phase method, based on the Langlie method and the D-optimality criterion, to overcome the intrinsic shortcomings of the staircase method used in estimating the fatigue limit distribution. This paper identifies the current challenges and provides an overview of existing solutions, setting the goal of developing an efficient data collection protocol. It further explains the application of D-optimality criterion and describes the Two-phase protocol, accompanied by a relevant example. The most significant advantage of this approach is its minimal requirement for pre-test information. A simulation-based study was executed to analyze the sensitivity of the input parameters and compare the effectiveness of the proposed method with the traditional staircase and Bayesian optimized method. The numerical simulations reveal that the proposed method offers improved estimation performance for the mean and standard deviation of the fatigue limit distribution, even with minimal pre-test information

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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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

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

Imam Salim b. Rashid and the Imamate revival in Oman 1331/1913 - 1338/1920
No full textThe principal aim of this thesis is to assess the performance of Imam Salim b.Rashid and the Imamate revival in Oman during the second decade of the 20th century. It
presents biographical information about Imam Salim, with special reference to the military and political policies by which he established and consolided his Imamate in the
Interior Province, and his relations with the Sultan and the latter's British supporters. An attempt is also made to explore the relationship between the Imam and the Omani tribes and to evaluate his administrative success. This thesis comprises eight chapters, and the introduction and conclusion. The introduction reviews the relevant literature on the topic. The first chapter describes the geographical setting and provides a historical background,
relating to three principal matters: the rise of the Iba<;liyyah and the development of the Imamate in Oman; the events in Oman after Sd. Sa'id's death up to 1913; and the effects of the First World War. The second chapter seeks to give an account of the career of Imam Salim's life and the Imamate revival. The third chapter discusses the manner in
which the Imam was elected, private and public allegiance (bay'ah) and the Imam's aims and policy programme. Chapter Four deals with the Imam's military operations and the
spread of his authority over Oman. Chapter Five examines the attempts at negotiation between the Imam and the Sultan, and the role of the British Government and the local
figures in this regard. Chapter Six is devoted to a discussion of the role of the tribes in support of Imam Salim, and the extent of the Imam's influence over these tribes. Chapter Seven assesses the Imam's administrative machinery, including the political system, the bureaucracy, education policy, and financial apparatus. Chapter Eight examines the causes behind the assassination of Imam Salim and the signing of the Treaty of al-Sib. In the conclusion, we present the findings of the research as they have emerged from the assessment of the course of events in Oman. We have said that the Omanis succeeded in reviving the Imamate and elected Imam Salim al-KharU~i who devoted his efforts to establish the foundations of the state, and peace prevailed in the country after the treaty of
al-Sib in 1920
