Most of the existing studies on the evolution of emergency topics in social media focused on the emergency information demand of fixed user type in emergency while ignoring the changing roles of stakeholders during the emergency. Thus in this study, a three-dimensional dynamic topic evolution model is proposed, in which fine grained division of time, dynamic identification of stakeholders in the emergency, and emergency topic evolution based on both timeline and stakeholder's type are all considered.

Particularly the relevance between the tweets posted and the topic of emergency, the influence on the social network, and the attention of emergency topic are as well taken into account to quantitatively calculate the weight and ranking of stakeholders at different stages of the emergency. To verify the proposed model, an experimental demonstration was carried out under an emergency event posted on social media.

The results show that (1) based on the three-dimensional dynamic topic evolution model, the composition and ranking of stakeholders have obvious differences at different stages; (2) the emergency information needs and the sharing behavior of stakeholders on emergency information also indicate different preferences where the topic concerns of stakeholders at different stages have a strong relationship with their weight ranking; (3) the emergency topic evolution considering both the dynamics of emergency stakeholders and emergency information demand could more accurately reflect the changing regularity of social media users' attention to information in emergency events.

This study is one of first to investigate the emergency topic evaluation on social media by considering the dynamic changes of various stakeholders in emergency. It could not only theoretically provide more accurate method to understand how users share and search emergency information in social media, but also practically signify an information recommendation way in social media for emergency tracking.

Post-merger integration (PMI) is driven by coevolving processes. By integrating the literature on acquisitions with that of knowledge networks, this paper highlights different reconstruction mechanisms for dual knowledge networks during PMI – namely, internal knowledge network coupling and external knowledge network embeddedness. This paper aims to examine their coevolutionary relationships with PMI.

A coevolutionary framework is tested using a latent growth model and cross-lagged models. The analysis is based on longitudinal data collected from 116 Chinese technology-sourcing overseas merger and acquisition firms.

This paper unearths a novel idea that variations in post-merger reconstruction of dual knowledge networks can explain why some acquirers increase the degree of integration faster than the others. The results show that the internal knowledge network coupling leads to more knowledge similarity and, in turn, causes a higher degree of integration. The external knowledge network embeddedness also causes higher relative network status of the acquirer, which consequently leads to a higher degree of integration. Furthermore, results from cross-lagged models confirm that an increase in the degree of integration positively influences subsequent changes in the internal knowledge network coupling and external knowledge network embeddedness, thus forming a coevolutionary relationship over time.

This paper responds to recent calls for more insights into the dynamics of PMI. By highlighting different reconstruction mechanisms for internal and external knowledge networks during PMI, this paper explains why it is important to understand PMI dynamics from a dual knowledge network perspective. This paper is the first to adopt a coevolutionary perspective and provide a more comprehensive dynamic framework between PMI and reconstruction of dual knowledge networks. Besides, this paper contributes to the research on emerging market multinational corporations’ cross-border merger and acquisition integration from a dynamic perspective, revealing the time effects of traditionally favored light-touch integration.

Most of the thousands of studies of leadership as well as strategic leadership in organizations choose as the unit of analysis the individual leader. This choice runs contrary to the often-observed fact that organizations have numerous leaders at all levels of the organization – in other words, a network of leaders, which permeates the formal organizational structure. The purpose of this paper is to re-conceptualize strategic leadership by advancing understanding of: the effects of variations in internal complexity and external turbulence and the effects of choices by the strategic leadership based on those variations.

The paper advocates a network approach to strategic leadership where there is a set of highly dynamic role changes, based on both human and social capital. The typology and propositions in the paper emerged over a period of many years of observation of organizations (direct and indirect) as well as reflection of theories on how strategic leadership actually occurs in medium to large-size profit-oriented organizations.

The paper proposes a model of strategic leadership based upon four modes of single actor and shared leadership (stars, clans, teams, and leadership networks). The paper sets forth propositions for the situational appropriateness of each of these four forms and identifies avenues for future research to advance the theory.

The paper cross-fertilizes extant research streams in leadership and strategic management to create a contingency theory of strategic leadership that is closer to what executives actually experience in the workplace.

Purpose – This paper aims to contribute to one's understanding of how beginning principals in Hong Kong exercise leadership by exploring the concurrent influence of their inner worlds and the external contexts on their leadership within a reforming environment.

Based on a study of the work lives of beginning principals in Hong Kong, this paper discusses a number of findings which attest to the complexity of the role of principals in a reforming environment and how this is influenced by an amalgam of personal and other contextual factors.

These include a set of categories and sub‐categories which help to frame an understanding of the work lives of beginning principals, and a rough typology of beginning principals.

The paper contains original data about secondary school beginning principals in Hong Kong, illustrating how their personal characteristics interact with other contextual features to shape their leadership.

Islamic Insurance (Takaful) played a dynamic role in Islamic Social Finance (ISF). The popularity of the Takaful concept is being increased with each passing day. To describe the process, it is important to understand past areas of research, research differences, areas of unknown Takaful research, as well as the existing data. However, the purpose of the paper is to provide a comprehensive analysis of the development of qualitative research by carefully examining the nature of science and aspects of social relations in ISF.

Field, concerns with analysing and measuring the scholarly literature, quantitative characteristics of sciences and scientific technologies are known as scient metrics. This research includes queries such as “Islamic Insurance”, “Takaful” and “Shariah Insurance” as a reference in “Article title, Abstract and Keywords” based on Scopus from 2002 to 2022. This analysis was conducted in February 2022. The Bibliometrics, R-Studio, VOSviewer and Excel software are used to analyse the collected data and apply the bibliometric analysis.

The gist of the results and findings is that there are clear research gaps in the existing literature on Takaful. The available research on this subject does cover historical background, concept and models of Takaful and customer satisfaction towards Takaful model. Very important areas such as use of technology for bringing innovation in Takaful products and Shariah issues in existing practice and their solutions were not found in the present literature on Takaful.

This is the comprehensive research article to examine current literature on Takaful with bibliometric analysis. Results and potential areas of this research could be much helpful for scholars and researchers to create more dynamic improvements in the scientific development of Takaful in ISF.

Over the past few decades, the higher education landscape underwent dramatic changes, causing strain on higher education institutions (HEI) worldwide. The academic debate is filled with very well-argued accounts of these developments. Advances in information and communication technology (ICT) add an additional layer to this already complex reality. Against this backdrop, it is necessary that the question of managing and administering HEI today be rethought. Emerging technologies such as artificial intelligence (AI) and cognitive computing, augmented, virtual and mixed reality (R+), Internet of Things (IoT), blockchain, bear the promise to effectively assisting HEI administrators in navigating their institutions through the period of profound change. This chapter offers a brief account of that.

The purpose of this study is to explore how the “New type of industry and research chain value creation project” promoted by the Ministry of Science and Technology in Taiwan can help universities to achieve university social responsibility (USR), promote social innovation, and achieve sustainable development. The university social responsibility defined in this study is proposed through literature analysis. The study interviewed three professionals who actually participated in the project and served as core positions. Semi-structured in-depth interviews were conducted. Key findings are drawn as follows. First, the term USR is multifaceted and needs further refinement in light of the changing and dynamic roles of universities. Second, the value creation plan helps universities achieve social responsibility. Third, the value creation team incorporates the concept of university social responsibility into the consideration of development factors, which contributes to the sustainability of the project. Fourth, the value creation plan faces the willingness of participants and the public's unclear understanding of university social responsibility. Finally, practical benefits include the joy of team members, the cultivation of talents and the dream of having a business.

In this chapter, we describe the challenge and experience to spread out information and communication technologies (ICT) and how to implement them progressively, in order to improve administrative, academic, and pedagogical issues. As a case study, institutional strategies to tackle these issues in the higher education institutions (HEI) that belong to the Instituto Politécnico Nacional of Mexico (IPN) are described. The main challenge of HEI to incorporate cutting-edge technology in order to form professionals according to educational models and needs of the worldwide is pointed out. Thus, the intended focus of this work is to elevate the discourse and generate awareness about information and communication technologies to translate the language for being legible and understandable to deans, directors, and general authorities of HEI so that they can clearly make decisions with respect to the benefits that current technologies bring to the education institutions, and thus they can keep in mind investing important economic resources in future and mature technologies. Nowadays, HEI of the IPN are facing problems regarding the allocation of budgetary resources, so the strategies and analytical discussion of how ICT can envision the growth of HEI is a very timely issue to be presented to the Mexican government.

The purpose of this article is to present a series of reflections on future scenarios distributed to Taiga Forum participants in March 2006.

Permission was obtained to reprint the scenarios, and select national library leaders, seasoned professionals and mid‐career librarians were invited to respond to these scenarios.

Taiga scenarios focus on broad areas – internal organizational structures, advances in information technology, changing user expectations. Local engagement with these scenarios will help staff prepare for the future. Scenarios lend themselves to a variety of uses, including in‐service training, staff development, team building. Scenario planning can easily be tailored to the specific needs of an institution.

The Taiga Forum was an invitation‐only event. Broader dissemination of the scenarios provides others not only with the opportunity to move beyond their borders in technical services, public services, collection development, or information technology, and transcend the traditional library organization, but also with the opportunity to develop new solutions.

A novel sexual adaptive genetic algorithm (AGA) based on Baldwin effect for global optimization is proposed to overcome the shortcomings of traditional GAs, such as premature convergence, stochastic roaming, and poor capabilities in local exploring. This paper seeks to discuss the issues.

The proposed algorithm simulates sexual reproduction and adopts an effective gender determination method to divide the population into two subgroups of different genders. Based on the competition, cooperation, and innate differences between two gender subgroups, the proposed algorithm adjusts adaptively sexual genetic operators. Furthermore, inspired by the acquired reinforcement learning theory based on Baldwin effect, the proposed algorithm guides individuals to forward or reverse learning and enables the transmission of fitness information between parents and offspring to adapt individuals' acquired fitness.

Global convergence of the proposed algorithm is proved in detail. Numerical simulations are conducted for a set of benchmark functions with different dimensional decision variables. The performance of the proposed algorithm is compared with that of the other evolutionary algorithms published recently. The results indicate that the proposed algorithm can find optimal or closer‐to‐optimal solutions, and is more competitive than the compared algorithms.

The proposed algorithm introduces, integrates and simulates correctly and adequately, for the first time, the mechanisms of sexual reproduction, Baldwin effect and adaptation to GAs by referring to the latest research results of modern biology and evolution theory.
