Reconstruction of cell lineage and spatiotemporal pattern formation of the mesoderm in the amphipod crustacean Orchestia cavimana
No full textCell lineage studies in amphipods have revealed an early restriction of blastomere fate. The mesendodermal cell lineage is specified with the third cleavage of the egg. We took advantage of this stereotyped mode of development by fluorescently labeling the mesodermal precursors in embryos of Orchestia cavimana and followed the morphogenesis of the mesodermal cell layer through embryonic development
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Exploring the Role of Soft Factors in Enhancing Digitalization Project Success: A Multi-layer Perspective Emphasizing the Influence of Individual, Team and Organizational Learning
Full text linkOver the past two decades, there has been a significant increase in the adoption of digital technologies within organizations, leading to the increase of implementation of digitalization projects. These projects are strategic initiatives that leverage digital technologies to facilitate organizational transformation. Despite their growing trend of undertaking digitalization projects in various sectors, these projects often experience high failure rates. One contributing factor to these outcomes is the tendency to prioritize technical factors and paying less attention to soft factors. Furthermore, digitalization projects have yet to gain widespread recognition within the project management field. This lack of popularity has resulted in a lack of widespread knowledge focused specifically on soft factors for these types of projects.
The aim of this thesis was to explore critical soft factors in the context of digitalization projects, to better understand how such factors can contribute to the success of such projects. This research addresses three specific questions, employing a three-phase approach similar to the dual funnel model. Following the dual funnel model, each segment of the dual funnel (top, middle, and bottom) yielded insights from various papers, each contributing to addressing one or more of the following three research questions:
RQ1: What are the challenges that organizations face in implementing digitalization projects?
RQ2: How do different soft factors rank in terms of their influence on the successful implementation of digitalization projects?
RQ3: What strategies and approaches have proven most effective in overcoming challenges related to the implementation of the highest ranking soft factor in digitalization projects?
The thesis is divided into two parts, where Part I presents the summary of the research conducted and integrates the theoretical background and key findings. Part II presents the 6 papers included in the thesis.
This research was not as straightforward as it might seem. Changes were incorporated throughout the process in response to emerging research findings. The research incorporated various qualitative methods such as interviews, case study, open-ended questionnaire, and archival data (document). In addition, a quantitative method was also incorporated through surveys. However, only one paper employed mixed methods incorporating both interviews and a survey.
Research Question 1 (RQ1) is primarily explored in Papers A, B and C. Paper A explores the interplay of soft factors in managing digitalization projects, revealing two key insights: firstly, it identifies three critical actors essential for the success of digitalization projects; secondly, it illustrates the inter-relationships among soft factors within the context of digitalization projects. Paper B examines the challenges in digitalization projects, emphasizing the crucial role of soft factors in managing the interactions between three key elements namely innovation, digital technologies, and organizing. It also points out three central factors in integrating these pillars which are team commitment, effective leadership, and a positive working environment. Paper C focuses on identifying the hinderances encountered in digitalization projects, highlighting the challenges involved in implementing and adopting such projects.
Research Question 2 (RQ2) is primarily addressed in Paper C and partially in Paper F. Paper C identified eight critical soft factors that are highly influential in the successful implementation and adoption of digitalization projects, with learning emerging as the top-ranked factor. This provides a clearer understanding of the priority and impact of these factors in the successful implementation of digitalization projects. Meanwhile, Paper F attests to the importance of learning for successful digitalization project outcomes.
Research Question 3 (RQ3) is primarily addressed in Papers D, E, and F, with additional insights from Paper C. Paper C presents an integrated framework, demonstrating that successful implementation and adoption of digitalization projects require readiness at multiple levels: organizational, project-based, and individual. Paper D focuses on the factors that hinder and facilitate learning within digitalization projects. It identifies key enablers such as the nature of the work, employee willingness, support from top management, and a supportive work environment. Paper E explores the «knowing-doing gap,» highlighting the discrepancy between the awareness of challenges in digitalization projects and the actions taken to address them. It reveals that while employees generally show a willingness to learn and adapt to digitalization changes, there is often a lack of similar commitment from top management to support learning and foster an environment conducive to it. Paper F focuses on the factors that add uncertainty to the project environment which then leads to identifying the challenges in managing digitalization projects. In addition, Paper F investigates strategies for effectively tackling the challenges posed by uncertainty in digitalization projects, offering insights and approaches to managing such uncertainty.
The main contributions of this thesis provide insights on the holistic management of digitalization projects through a learning-focused approach. This involves incorporating perspectives from all three levels: individual, project, and organizational, to gain a comprehensive understanding of the factors driving success and the crucial interrelationships among these levels. Focusing solely on one level risks missing other challenges and overlooks potential solutions critical for effectively addressing these challenges. This thesis underscores the importance of an integrated approach, as illustrated below, to ensure that learning and response strategies encompass all organizational tiers, thereby effectively navigating the complexities inherent in digitalization projects
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
