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.

This chapter details the theory of information worlds and its relation to studies of information behaviour, providing a framework for examining information behaviour in a variety of settings. Since information and its related technologies impact every aspect of life in advanced societies, it is of great importance to create a stronger theoretical understanding of information beahviours across social contexts. Information behaviour is simultaneously shaped by immediate influences, such as friends, family and other trusted small world sources, and by larger social influences, including public sphere institutions, media, technology and politics. Information behaviours of all sorts are situated and contextualized, given meaning by the multi-tiered contexts within which they occur. Drawing on the works of Jürgen Habermas, who studied information flow across the largest social structures, and Elfreda Chatman, who focused on the smallest social units, the theory explores information behaviour across all of the levels –– the small worlds of everyday life, mediating social institutions and technologies, the concerns of an entire society and broad political and economic forces. After detailing antecedents and exploring the theory's core concepts, the chapter investigates the theory's relevance for research on information behaviour and discusses the theory in light of other approaches to studying information behaviour, arguing that it provides a strong foundation for understanding and analysing the complex interwoven contexts within which we interact with information.

A small-world network is a type of network structure in which nodes are highly clustered and at short distances without being directly linked. This article analyzes whether the network of interlocking directorates among the largest Brazilian corporations follows a small-world network structure and if the small-world properties (high clustering and short distance between nodes) influence the occurrence of M&A at the domestic and international level.

The authors tested hypotheses regarding the relationship between small-world network properties and M&A based on a sample of large publicly-listed corporations in Brazil for the time series of 2000–2015 and using network analysis and regression techniques (probit and OLS).

The results show that while the Brazilian corporate network fits the small-world features of high clustering and short path lengths, only the distance among connected firms has a significant effect on international M&A: the shorter the distance between firms, the more likely firms undertake M&A abroad. Moreover, being integrated into the main component has a significant positive effect on national and international M&A. These findings suggest that the information and knowledge to undertake M&A can be better acquired by belonging to large business communities and not local cohesive clusters.

This research contributes to theories and ongoing debates about the network effects on organizational decisions and the determinants of M&A in emerging markets. In addition, this is the first study to analyze the impact of small-world networks on international M&A while controlling for country-level variables.

The present study increases our understanding of strong power in exchange networks by examining its incidence in complex networks for the first time and relating this incidence to characteristics of these networks. A theoretical analysis based on network exchange theory (e.g., Willer, 1999) suggests two network characteristics predicting strong power; actors with only one potential exchange partner, and the absence of triangles, that is, one's potential exchange partners are not each other's partners. Different large-scale structures such as trees, small worlds, buyer–seller, uniform, and scale-free networks are shown to differ in these two characteristics and are therefore predicted to differ with respect to the incidence of strong power. The theoretical results and those obtained by simulating networks up to size 144 show that the incidence of strong power mainly depends on the density of the network. For high density no strong power is observed in all but buyer–seller networks, whereas for low density strong power is frequent but dependent on the large-scale structure and the two aforementioned network characteristics.

This paper serves to test the validity of Chatman’s theory of “Life Lived in the Round” within a modern prison context. In particular, it examines Propositions Five and Six of her theory.

Data regarding the information-seeking practices of Australian adult female and male prisoners from maximum-, medium- and minimum-security facilities was gathered through 106 surveys and 27 semi-structured interviews. Participants’ information-seeking from sources internal and external to the “small world” of the prison was described. The information behaviours of the participants were examined against Chatman’s theory of “Life in the Round” to determine its applicability in the prison context.

The data gathered does not support Chatman’s theory of “Life Lived in the Round”, despite that theory being developed in a prison context. Neither Proposition Five nor Proposition Six of Chatman’s theory can be supported when examined in the light of the current data.

The inability of the data to support Chatman’s theory requires a reassessment of the applicability of the theory, at least to the prison context. As the theory was generated in part from a prison study, the foundational understandings of the theory could be questioned as a result of this current research.

Although Chatman’s theory has been examined against the information behaviours of other “Small World” communities, none of these studies have taken the theory back to the prison context from which the theory was developed. This study is also novel as its findings do not support Chatman’s theory, in contrast to other previously published examinations.

Explores the multiple impacts of globalization on work and employment in contemporary organizations. Covers the human resource management implications of organizational responses to globalization. Examines the theoretical, methodological, empirical and comparative issues pertaining to competitiveness and the management of human resources, the impact of organisational strategies and international production on the workplace, the organization of labour markets, human resource development, cultural change in organisations, trade union responses, and trans‐national corporations. Cites many case studies showing how globalization has brought a lot of opportunities together with much change both to the employee and the employer. Considers the threats to existing cultures, structures and systems.

This paper aims to examine the hypotheses of main international theories (realism, liberalism and constructivism) and the development of these theories toward the behavior of foreign policy of small states in the developing world. The theories of international relations, especially the realistic theory, face a theoretical debate and a fundamental criticism. The hypotheses of these theories are not able to explain the external behavior of some small states, especially those in the developing world such as Qatar. In particular, these small states do not have the elements of physical power through which they can play this role. However, they are based on the internal determinants (such as political leadership and the variable of perception) and non-physical dimensions of power to play an effective and influential external role.

This topic sheds light on the hypotheses of theories of main international relations, which explain the behavior of foreign policy of small states. This is due to the increased number of such states after the disintegration of Soviet Union, the practice of some countries an effective foreign role and the transformation of the concept of power from the hard power to soft power, and then to smart power

The theories of international relations, especially the realistic theory, face a theoretical debate and a fundamental criticism. The hypotheses of these theories are not able to explain the external behavior of some small states, especially those in the developing world such as Qatar. In particular, these small states do not have the elements of physical power through which they can play this role. However, they are based on the internal determinants (such as political leadership and the variable of perception) and non-physical dimensions of power to play an effective and influential external role.

The importance of the study comes from its interest in small countries in general and the Qatar situation in particular. The small country emerged as a player independent of the Gulf Cooperation Council, unlike what prevailed before, which led to the discussion of a regional role for Qatar despite its small power compared to the strength and size of other factions in the region such as Turkey, Israel and Iran.

Syndicated investments in startups within a particular industry follow an evolutionary path consistent with models of industry growth and evolution. Some industries spend a long time gestating, while others grow and mature quickly. Entry into ecommerce industry segments has both characteristics. What spurred the sector's slow emergence and subsequent quick rise? One obvious answer is the development of the Internet in the mid-1990s. However, a competing possibility is that the diffusion pattern resembles an epidemic among venture capital firms. This chapter examines how the existing structure of the VC syndication network in the US enabled such an epidemic. Consistent with existing theory on the spread of a disease in a small world, this study argues that the incidence of investments in ecommerce startups was a function of prior investments located on shortcuts in the network. The time frame is 1980 to just before the NASDAQ boom in 1999.

The small accounting practice, despite being the most numerous part of the profession by number of firms, remains largely under-researched. Part of the reason the small practice category remains elusive is that researchers find it difficult to precisely define the object to study, and yet, this may be precisely the reason for studying it. Envisaging how this category is “represented” in institutionalized settings, constitutes a rich agenda for future research as it allows the small practitioner world to be connected to the issue of intra-professional segmentation. The paper aims to discuss these issues.

This paper proposes reinvigorating research around Bucher and Strauss’ (1961) conceptualization of professions as “segments in movement”. At the same time as advocating a better investigation of the small practitioner segment itself, it suggests to take the latter as an example to further explore the vision of professions as segments “more or less delicately held together”. To this end, there is a potential for cross-fertilization between Bucher and Strauss’ research programme and a range of other theoretical frameworks.

The discussion points towards how small practice, as a segment whose history and characteristics reflect the different struggles that have led to the creation of the professional accounting body and marked its subsequent evolution, is far from insignificant. Segmenting the profession in categories related to “size” offers an opportunity to deal with an under-investigated aspect of professions’ sociology and history, which encapsulates its inherent diversity and hierarchy. Whilst the professional body may replicate the hierarchy that structures broader society, the meaning of small itself, within a hierarchy of organizations, is also a relative concept. It is politically charged, and must be delicately managed in order to maintain harmony within the polarized professional space.

The small practitioner has been much overlooked in the accounting literature, and the literature on the professions has overemphasized aspects of its cohesiveness. The authors contribute a revitalized agenda for researchers to explore the dynamics of heterogeneity and unity in the professional body, by focusing a lens on the small practice and extending the “segments in movements” premise beyond the functional division of professions.

The purpose of this paper is to better understand the constraints related to developing small-scale public-private partnerships (PPPs) and how to reduce them.

The paper provides a general review of the characteristics of small-scale PPPs and identifies overarching concerns.

The paper finds for small-scale PPPs constraints with respect to the definition, government processes and procedures, transaction costs, public capacity and institutional structure; important issues of transaction costs, minimum size requirement and increasing popularity and recommendations for further development.

Since most small PPPs are conducted by cities and regional governments, many local bodies would benefit from a better understanding of small-scale projects, helping to develop standard documentation, which is especially relevant for small-scale projects given their relatively large transaction and bid costs, supporting the long-term growth of small PPPs.

Small-scale PPPs have different characteristics compared with large projects and these characteristics should be studied separately. Although the benefits of small-scale projects are undeniable, relatively few have been undertaken relative to the substantial requirement. A more thorough understanding of the constraints related to developing small-scale PPPs and how to reduce them would help the subset of small projects to reach its full potential. This paper serves as a first step, clearing the ground for further research in specific areas.
