Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

No full textVariations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Shaping mega-event flagships: case studies ofthe big four of Expo 2010 Shanghai China
No full textAs spotlighted urban occurrences of significant global influence, mega-events such as the Olympics and the Expos usually create a great demand for mega-event flagships (MEFs). These purpose-built cultural, civic or sports landmarks not only serve as prominent event venues but often play a catalytic role in long-conceived renewal initiatives on a much broader scale. Lacking no successful event stories, it is not unusual to hear prominent post-event failures in MEFs. Despite its lasting appeal, such a highly controversial and challenging development has received surprisingly little in-depth analysis in existing literature. Academic interests have long concentrated on assessing impacts rather than profiling risks. Moreover, to realize such a dually oriented initiative clearly needs a competitive organization. Yet, this driving force behind becomes another understatement. Apart from tangential studies on western-based practices, pinpoint research is rare in emerging economies towards which MEFs are shifting their grounds. Such a triple imbalance may likely keep ambitious yet inexperienced hosts ignorant of tremendous risks behind overstated rewards.
To argue that MEFs should be pre-post oriented than treated simply as a legacy issue, this study presents four landmark cases of Expo 2010 Shanghai China – a mega-event as not only a crowning touch to China’s thirty-year economic rise but a catalyst for Shanghai’s renaissance towards a global center. As the centerpieces of this mega-undertaking, the Big Four (the Big4) represent the largest MEF cluster in history and the latest epitome of major projects of national significance. To explore how the Organizer has forged the sixty-year vision beyond the six-month extravaganza, participant observation is adopted due to the author’s special role as a key project coordinator of Expo 2010 during the early stages of the Big4. In gaining more useful insights for future practices, this multiple-case study takes the following three steps. First, rationales and practices of MEF development are analyzed through a historical review of eight selected cases of mega-event built legacies in five countries over 150 years. Next, programming practices of MEFs and non-MEFs in China are investigated through a pilot questionnaire survey in 2009. Finally, the 600,000-sq.m Big4 are explored respectively and collectively against the ongoing Trilogy of the Huangpu Riverfronts Renewal.
Multifold findings from previous and present cases confirm the hypothesis that MEF development is rather an issue of dualism than dichotomy. To meet existing and emerging challenges, a framework plan is developed containing four approaches and ten steps key to the vitality of MEFs. Conclusions are made from both local and global dimensions. Four major breakthroughs, two pressing problems and two emerging trends are identified for major project developments in China; whereas six essential conditions to sustain MEF development are generalized for significantly comparable cases worldwide. A timely reminder of rethinking the commitment to MEFs and a much-needed complement to related western literature, this pioneering research would be of cross-boundary value and spark interdisciplinary interest.published_or_final_versionReal Estate and ConstructionDoctoralDoctor of Philosoph
An investigation of safety climate on Hong Kong construction sites
No full textKeeping stakeholders far from danger is even more urgent for the construction industry which features higher than average accident and fatality rates worldwide. Improving safety proactively and thus saving huge losses incurred through cultivating safety climate (i.e. people’s perception and attitude of safety policies, procedures, and practices at workplaces) has been advocated and studied since 1980s. Nevertheless, the issue remains that what are the antecedents and how do they impact on safety climate and hence safety behavior at the individual level. With the construction industry of Hong Kong in perspective, a plateau of accident statistics reached since the entry into the new millennium calls for research into possible human factors behind the scene. Against such backdrop, the investigation is carried out in an attempt to tackle the issue with both theoretical and practical implications.
With the aim at a better understanding of the research question, a two-stage mixed method research design featured with both qualitative and quantitative approaches is adopted. At the first stage, based on extant literature and 17 interviews with local construction practitioners, antecedents of safety climate are ascertained and categorized into five general perspectives, i.e. structural perspective, perceptual perspective, interactive perspective, cultural perspective, and to-be-confirmed perspective capturing factors not belonging to the first four perspectives. To increase the conceptual precision of safety climate and reveal the working mechanism of safety climate, a series of safety climate related outcomes are integrated into an initially hypothesized research model. Measurement instruments and practical relevance of latent constructs of interest are obtained by literature review and interviews. At the second stage, a large scale questionnaire survey targeting at construction practitioners across Hong Kong and case study of a local civil engineering project are conducted concurrently.
Based on 292 valid responses, most of the bi-variate correlations between constructs demonstrate support for the hypothesized relationships, despite of some unexpectedly weak effects implied by path coefficients of the initial structural model. After modification based on theory and practice, the modified structural model reveals four routes to forming safety climate, i.e. 1) sound organizational climate through fluent leader-member exchange; 2) client involvement via enforcing safety management system; 3) individualism leading to negative safety climate; and 4) sound supervisory practice contributing to positive safety climate. Furthermore, the revised model confirms the previously found relationships among safety climate and its related outcomes. Learning from the case study which involves six interviews, participant observations of onsite meetings, and analysis of documents including safety plan, safety manual, minutes of safety related meetings, and content analysis of the primary 17 interviews generally corroborate the findings. Taken together, the research achieves the established objectives, provides a framework for future investigations into antecedents of safety climate, and hence suggests that safety is an emergent property of a complicated socio-technical system, involving diversifying factors.
The implications of the findings have for devising safety interventions are discussed in the conclusion section, along with limitations and future research directions.published_or_final_versionReal Estate and ConstructionDoctoralDoctor of Philosoph
