Strengthening cybersecurity in Singapore : challenges, responses, and the way forward
No full textThis chapter uses a historical perspective to examine the development trajectory of e-government in Singapore, the trends and patterns of cybercrimes and cyber-attacks, and the measures taken by the government to combat cybercrimes and cyber-attacks. It shows that the government has adopted a proactive, holistic, and cooperative approach to cybersecurity in order to tackle the ever-increasing cybersecurity challenges. It has regularly reviewed and improved cybersecurity measures to ensure their effectiveness and strengthened its defense capabilities over time through coordinating national efforts with public and private sectors and cooperating with regional and international counterparts. The chase for a perfect cybersecurity system or strategy is both impossible and unnecessary. However, it is important and necessary to establish a cybersecurity system or formulate a cybersecurity strategy that can monitor, detect, respond to, recover from, and prevent cyber-attacks in a timely manner, and make the nation stronger, safer, and more secure.Published versio
Refining Ethical Reflections in Cybersecurity Policy and Privacy: Insights for Policy Makers
No full textAs governments and organizations seek to strengthen cybersecurity measures, ethical considerations play a crucial role in shaping effective and responsible policies. This research article explores the ethical dimensions of cybersecurity policymaking, focusing on the balance between security imperatives and individual privacy rights. Drawing on principles of ethics, human rights, and legal frameworks, the article discusses challenges and dilemmas faced by policymakers in ensuring cybersecurity without compromising privacy and civil liberties. It proposes a set of ethical guidelines and best practices for designing and implementing cybersecurity policies that are both effective and respectful of fundamental rights and values

Cyber-Ethical Leadership in Higher Education: A Practice-Based Framework for the Digital Age
Full text linkThe rapid digitization of higher education has introduced complex ethical challenges that demand new forms of leadership. This paper explores the concept of cyber-ethical leadership as a critical response to evolving issues such as data privacy, AI-generated academic content, digital surveillance, and cybersecurity crisis management. Drawing from real-world case studies and institutional practices, we propose a practice-based framework that emphasizes ethical reflexivity, participatory governance, and multi- stakeholder engagement. By reframing leadership as ethical agency rather than hierarchical authority, this study highlights how leaders in academia can navigate digital dilemmas through context-aware, inclusive decision-making. The findings call for the integration of digital ethics into institutional policy, leadership training, and crisis preparedness, contributing to a more resilient and ethically grounded digital transformation of higher education
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
