Abstract

Purpose

The purpose of this paper is to attempt to provide a review of the growing literature on co-authorship networks and the research gaps that may be investigated for future studies in this field.

Design/methodology/approach

The existing literature on co-authorship networks was identified, evaluated and interpreted. Narrative review style was followed.

Findings

Co-authorship, a proxy of research collaboration, is a key mechanism that links different sets of talent to produce a research output. Co-authorship could also be seen from the perspective of social networks. An in-depth analysis of such knowledge networks provides an opportunity to investigate its structure. Patterns of these relationships could reveal, for example, the mechanism that shapes our scientific community. The study provides a review of the expanding literature on co-authorship networks.

Originality/value

This is one of the first comprehensive reviews of network-based studies on co-authorship. The field is fast evolving, opening new gaps for potential research. The study identifies some of these gaps.

Abstract

Online social networks are increasingly important venues for businesses to promote their products and image. However, information propagation in online social networks is significantly more complicated compared to traditional transmission media such as newspaper, radio, and television. In this chapter, we will discuss research on modeling and forecasting diffusion of virally marketed content in social networks. Important aspects include the content and its presentation, the network topology, and transmission dynamics. Theoretical models, algorithms, and case studies of viral marketing will be explored.

Abstract

Purpose

Research on entrepreneurial ecosystems has advanced over recent years and has become a popular topic. Despite the interest, previous work has focused on entrepreneurial ecosystems in large cities in the United States. Ecosystems in small cities, underpopulated rural areas, university towns and outside the USA have not been considered much. This paper begins to address this deficit by reviewing three groups of literature.

Design/methodology/approach

From the review, the paper builds a conceptual framework to consider entrepreneurial ecosystems led by universities. After summarizing the literature on entrepreneurial ecosystems, entrepreneurial universities and entrepreneurship education, the paper suggests a conceptual framework outlying the structure, components and mechanisms that enable universities to operate as catalysts in the creation of entrepreneurial ecosystems.

Findings

It is evident that on many of the “ingredients” of a successful entrepreneurial ecosystem, a resource-constrained environment would have many gaps. Building an entrepreneurship ecosystem in such contexts would be inherently challenging. The model presented suggests that the presence of a university in such locations should enhance the prospects of progress but that the nature of the university itself would impact any outcomes. Universities that make concerted efforts to be entrepreneurial and that have entrepreneurship programmes have strategies available to them that can enhance entrepreneurship ecosystems over time.

Originality/value

The contribution of this paper is to show “how” a university and its entrepreneurship programme can operationally address deficits in a local ecosystem and how it might bring about positive change. The paper also opens new avenues for entrepreneurship education researchers.

Abstract

Purpose

The purpose of this research is to address the need for a definition of metadata descriptors for use in enhancing the accuracy of bibliometric instruments of scholarly evaluation, such as the impact factor.

Design/methodology/approach

A semantic vocabulary – COAP – is constructed, deployed on top of the Resource Description Framework (RDF), by extending the Friend‐of‐a‐Friend (FOAF) schema.

Findings

An extension of the FOAF vocabulary is considered as the ability to describe a publication record such as this paper in terms of scholar contributions and participations. In order to achieve that, the FOAF vocabulary is extended.

Practical implications

The application of this semantic vocabulary could be used as a way of enhancing the accuracy of source data for bibliometric evaluation instruments.

Originality/value

The paper discusses how metadata descriptors can contribute to the improvement of already established scholar evaluation instruments such as the impact factor. It will be of use in the development of digital libraries.

Abstract

There is an erroneously held view that postal surveys cannot achieve sufficient response rates to overcome non‐response bias and are best suited when budgets are limited. This article reviews the increasing number of published studies which show that, with planning, high response rates can be achieved. It reports on a survey of members of the Postal Research Special Interest Group (formed under the auspices of the Market Research Society). Current postal research practice is highlighted and inferences drawn about the mechanics associated with high response rates.

Abstract

Bipartite networks (e.g., software developers linked to open-source projects) are common in settings studied by organization scholars. But the structure underlying bipartite networks tends to be overlooked. Commonly, two modes are reduced to one mode for analysis, causing loss of information. We review techniques for projecting 2-modes onto 1-mode and discuss 2-mode measures of clustering. We also address the potential for 2-mode theory development concerning (a) how change in one mode influences change in the other, (b) the question of two types of agency, and (c) how diversity in one mode is a substitute for diversity in the other mode.

Abstract

This chapter aims to provide a short overview about the situation of Roma in Hungary. Starting from the question ‘Who are the Roma, Gypsy in Hungary?’, this chapter introduces several researches on Hungarian Roma. The linguistic groups of Roma are briefly outlined to make it clear how much the Hungarian Roma are heterogeneous. The social situation of the Roma, as minority in Hungary, is also detailed by introducing geographical location and housing and employment regarding to Roma. Based on these general data on Hungarian Roma, this chapter aims to focus on educational situation of the Roma minority in Hungary, including – primary and secondary school education, education in special schools, education in college and university, adult education, school success supporting educational initiatives and programmes like extracurricular programmes. As a summary, this chapter introduces some further researches by short abstracts in order to provide a suitable starting point for those who are willing to get know more about this minority in Hungary.

Abstract

In this chapter we investigate the ownership and control of UK firms using contemporary methods from computational graph theory. Specifically, we analyze a ‘small-world’ model of ownership and control. A small-world is a network whose actors are linked by a short chain of acquaintances (short path lengths), but at the same time have a strongly overlapping circle of friends (high clustering). We simulate a set of corporate worlds using an ensemble of random graphs introduced by Chung and Lu (2002a, 2002b). We find that the corporate governance network structures analyzed here are more clustered (‘clubby’) than would be predicted by the random-graph model. Path lengths, though, are generally not shorter than expected. In addition, we investigate the role of financial institutions: potentially important conduits creating connectivity in corporate networks. We find such institutions give rise to systematically different network topologies.

Abstract

Purpose

The purpose of this paper is to present a P2P network security pricing model that promotes more secure online information sharing in P2P networks through the creation of networks with increased resistance to malicious code propagation. Online information sharing is at an all‐time high partly due to the recent growth in, and use of, online peer‐to‐peer (P2P) networks.

Design/methodology/approach

The model integrates current research findings in incentive compatible network pricing with recent developments in complex network theory. File download prices in P2P networks are linked to network security using a graph theory measurement called the Pearson coefficient. The Pearson coefficient indicates a structural dimension of scale‐free networks (scale‐free networks like the internet) called preferential attachment. Preferential attachment refers to the network property where the probability for a node to connect to a new node is greater if the new node already has a high number of connections.

Findings

The P2P network security pricing model concept is illustrated to show how the model functions to create more secure P2P networks.

Research limitations/implications

Future research in P2P network security pricing should focus on testing the model presented in this paper by numerical experiments and simulation including the tracking of malicious code propagation on networks grown under the pricing model.

Originality/value

The P2P network security pricing model demonstrated here is a different approach to network security that has a strong potential to impact on the future security of P2P and other computer based networks.

Abstract

Purpose

The purpose of this paper is to identify the main environmental impacts of coal mining in China, examine the main institutions and reform factors that failed the control of these damages, and discuss what would be necessary to establish a sustainable and environmentally responsible coal mining sector in the context of market and institutional reforms.

Design/methodology/approach

Review of existing knowledge, and semi‐structured interviewing with key informants in the policy and industry sectors has been the main method of primary and secondary data collection. Grounded theory was used to analyze original data.

Findings

The large and fast growing coal industry in China has caused significant environmental degradation, including land subsidence and water intrusion, as well as remarkable records of miner's poor safety and health. Market reform was mostly unsuccessful in integrating environmental consideration into production and marketing decisions. Main factors of reform that have been associated with this problem are price deregulation and excessive competition inside the industry. Institutional reform, in fact, enhanced the status of State Environment Protection Agency; however, it impaired environmental governance in the coal industry. It is suggested that market reform as applicable to the China coal industry economic sector in particular should reconsider its approach in light of the numerous problems it has created.

Originality/value

The paper identifies and puts together the condition of the growing coal industry in China after market reform, articulating the huge environmental costs that this development has imposed on the country, while calling for an environmentally sustainable coal industry.
