Bone mechanics and cell populations: mathematical description and parametric study of the model
No full textIn this paper we study a recently proposed mathematical model for the description of the mechanics of bone as well as bone remodeling processes and bone cell populations dynamics. We investigate the biological meaning and a suitable value for the numerical parameters of the model. To do so, we compare biological data with a systematic numerical investigation of the model. We also propose some corrections to the original model aimed at better describing the observed phenomena
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
Variations on the Author
No full text“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
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
Modelling and optimization of a transit services with feeder bus and rail system / Mohammadhadi Almasi
No full textmany passengers use transit systems to reach their destination, while a growing concern for public transit is its inability to shift passenger‘s mode from private to public transportation. By designing a well-integrated public transit system and improving the cost-effectiveness network, public transport could play a crucial role in
passenger satisfaction and reduce operating costs. The main objective of this research is to develop a mathematical formulation model for designing and coordinating schedules
of integrated public transit services, which includes development of feeder services and coordination with major transportation services and transfer time consideration between two modes (i.e. Feeder bus and LRT). In the proposed improved model, the additional terms and constraints employed in objective function provide more accurate and efficient solutions for various conditions of transit systems, and this may lead to the creation of a more realistic model in simulating real-life problems. This is followed by application of the improved model to the benchmark and Petaling Jaya study areas. In this study, optimized transit services and coordinated schedules are developed using metaheuristic algorithms such as genetic algorithm (GA), particle swarm optimization (PSO), water cycle algorithm (WCA) and imperialist competitive algorithm (ICA). The data of the study were obtained based on the literature review, questionnaire survey and observation. Finally, obtained numerical results of the proposed model including optimal solution, statistical optimization results, the convergence rate as well as comparisons were discussed in detail. Therefore, optimum transit network was obtained by using ICA and WCA. As a result, the corresponding network costs obtained by PSO and GA are greater than ICA and WCA
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
Benefits, Co-Benefits, and Trade-Offs in Natural Water Retention Measures: a Review of Classifications and Indicators
No full textIn recent years, natural hazards related to climate change, such as extreme floods, droughts and heatwaves, have increased in magnitude and frequency. In response, Natural Water Retention Measure (NWRM), as a vital strategy to mitigate these challenges, focuses on increasing and/or restoring the retention capacity of soil and aquatic ecosystems. NWRMs can have positive impacts that may lead to several benefits and co-benefits. They can also have some negative impacts, in the form of trade-offs. To assess the efficacy of NWRMs, it is essential to consider and evaluate both multiple benefits and trade-offs in a comprehensive framework and use appropriate indicators for their assessment. Through a literature review, it is found that there is no thorough study that examines the different types of benefits and co-benefits, provides a complete classification of the benefits and co-benefits of NWRMs, and introduces various indicators for their evaluation. In addition, trade-offs associated wi..
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
The Thursday Murder Club: Launching a megabrand author - a publishing case study
No full textIn 2020, the Christmas book charts in the UK made headlines: Barack Obama’s eagerly awaited autobiography, The Promised Land, was beaten to the top spot by The Thursday Murder Club by Richard Osman, a debut cosy crime novel set in a retirement village. Not only did Osman’s book beat the former US president’s expected bestseller, it also broke records, becoming the fastest-selling debut crime novel of all time. Although Osman has a certain level of fame in the UK from his TV appearances on shows such as Pointless, his celebrity status does not entirely explain the novel’s huge sales. This article tracks the acquisition, publication, and promotion journey of The Thursday Murder Club in order to understand the industry and cultural context of its success and to interrogate the role of celebrity in the creation of author brands. The findings suggest that the unexpected scale of the success of the book owed to a number of factors, including in-depth editing by the novel’s agent, editor, and author to tighten up the plot, an extensive and strategic promotional campaign, the pandemic (which drove interest in the book’s genre and themes), and the quality of the writing. We find that the book’s success was accentuated by Osman’s celebrity status rather than being entirely reliant on it. This research adds to the growing scholarship on celebrity authorship by means of an in-depth case study and provides insight into the processes behind publishing a ‘celebrity’ book and launching a megabrand author
A study on participatory management and conservation of mangrove ecosystem in Matang and Carey Island, Malaysia / Mehdi Almasi
No full textManagement of mangrove forests is vital, especially for the conservation and revival of mangrove resources. Community-based mangrove forest management with involvement of various stakeholders could be an effective way for the conservation of the rich ecosystem of mangrove forests. The present research aims to formulate a participatory management strategy to conserve mangrove forests in the Matang Mangrove Forest and Carey Island in Malaysia as the participatory approach in management has not been well addressed in the literature on mangrove forest management in this country. The major management tool is a SWOT matrix analysis. For this purpose, the analysis of the data collected from in-depth interviews (31 for the Carey Island and 35 for Matang) with local people living in both areas of research as well as the information from the researchers’ observation resulted in identification of a series of internal and external factors in the targeted areas in terms of conservation of the mangrove forest. The factors were then scored using a SWOT questionnaire filled by respondents (312 for the Carey Island and 377 for Matang). Resulting in sixteen strategies (for both research areas) were considered using SWOT matrix and pairwise matching for the conservation of the mangrove forests. Later, the Quantitative Strategic Planning Matrix (QSPM) was used and prioritized strategies were determined. As a conclusion, the prioritized strategies in the Carey Island were all related to capacity building, involvement and participation of stakeholders in the process of the mangrove forest conservation. Therefore, mangrove forest management requires a participatory approach in a way that not only the mangrove harvesting would be sustainably controlled, but stakeholders, especially villagers, will be simultaneously empowered and take responsibility of the sustainable conservation of their habitat and its biodiversity. In the Matang Mangrove Forest, it was concluded that participation of local communities in the management of the Mangrove forest is the key element of the priority strategies
