“…Generally, users with more friends in the network would have greater impact on spread speed as well as the information popularity [110], and it is also a very important yet simple metric to evaluate the user's influence in social science. Other features of the network toplogy, including the degree distribution [111], small-world structure [93], ego structure [112,113], tie strength [114,115] and the ideological homophily in affiliation [116], all played very important roles in information spreading. For example, Bakshy et al found that weak ties would play a more dominant role in the dissemination of information online than currently believing that more weak ties were responsible for the propagation of novel information [109].…”

The ongoing rapid expansion of the Word Wide Web (WWW) greatly increases the information of effective transmission from heterogeneous individuals to various systems. Extensive research for information diffusion is introduced by a broad range of communities including social and computer scientists, physicists, and interdisciplinary researchers. Despite substantial theoretical and empirical studies, unification and comparison of different theories and approaches are lacking, which impedes further advances. In this article, we review recent developments in information diffusion and discuss the major challenges. We compare and evaluate available models and algorithms to receptively investigate their physical roles and optimization designs. Potential impacts and future directions are discussed. We emphasize that information diffusion has great scientific depth and combines diverse research fields which makes it interesting for physicists as well as interdisciplinary researchers.

“…Structural embeddedness lays stress on an enterprise's position in its ego-network which is considered as a portion of a social network formed of the one (called ego) and others with whom the ego has a social relationship (called alters) (Arnaboldi, Conti, Gala, Passarella, & Pezzoni, 2016), and their linkages (Gulati & Westphal, 1999). This type of network embeddedness, which influences economic exchange through the configuration of linkages among actors and the architecture of networks, emphasizes network ties, network densities, and the scale of enterprise networks (Polidoro, Ahuja, & Mitchell, 2011;Ruiz-Ortega et al, 2018;Tang, Rai, & Wareham, 2011).…”

Despite the considerable amount of research regarding trust as one of the most important characters and competitive advantages for an industrial cluster, few empirical studies have examined whether geographic proximity still leads to higher levels of trust in the current Internet era. This article explores this issue of trust from a network embeddedness perspective. Based on the data from Zhongshan gas appliance cluster, we employ structural equation modeling to examine the extent to which relational embeddedness, structural embeddedness, and positional embeddedness have any impact on trust-building in the cluster. Our findings reveal that high clique trust and low aggregate trust coexist in the cluster, showing that the effect of geographical proximity on trust has been weakened and is no longer a sufficient condition for trust-building. This study also gives some suggestions on how to improve the trust within a cluster through network governance.Lez Rayman-Bacchus is a research follow in the Business School, University of Winchester, United Kingdom. He also founded the Centre for Corporate Responsibility at London Metropolitan University, and the international symposium on Corporate Responsibility and Sustainable Development. His research interests include the practice of strategy and international management, currently focused on Chinese SME attitudes and behavior in industrial network clusters, and that of Middle Eastern businesses. He has a background in both industry and academia. He spent more than 15 years with high technology multinational companies working in business development and marketing, before moving into research and teaching on strategy, corporate responsibility and sustainability, corporate ethics, and corporate governance. He has published more than about 30 papers as well as one academic book.GuangMing Xiang is pursuing master's degree in finance at the School of Management and Economics in UESTC.

“…This was important because the existing faculty-student relationship might enable us to influence both the faculty and its students to undertake tasks for us. Envisioning an ego network, where we are the centre research unit, helped us to understand how the university network expands graphically towards students all over the country (Arnaboldi, Conti, La Gala, Passarella, & Pezzoni, 2016). This enabled us to understand that our research unit has strong ties with our first-degree connections, who are the university staff from different faculties; and from the faculties' strong ties with their enrolled students, we were able to exert influence over those students, who are second-degree connections for us ( Figure 1).…”

This article presents the results from an investigation that used a qualitative perspective of a descriptive type to identify the inclusive educational processes from 707 preschool and primary education schools in Colombia, distributed around 26 territorial units out of a total of 32. To obtain all this information around the country, a data collection strategy was applied, which we named the distributed access research strategy (DARS). All the data was collected by tertiary education students from two programs of the Faculty of Education, Corporación Universitaria Iberoamericana in Colombia. The results revealed that most preschools and primary schools have documented institutional educational plans referencing diversity and inclusion for their students, but they have difficulties in establishing strategies to identify and implement curricular adaptations within their contexts, as well as with the use of tracking instruments. These results generated a reflection for reviewing the syllabus and study plans in the tertiary education programs at this university to better prepare future teachers who will face such scenarios in their locations across the country. Moreover, this new DARS data-collection strategy shows an interesting potential, which is generic enough to enable unlimited research topics to be explored within distance learning contexts.
