Regular Spacing

Mitochondrial DNA (mtDNA) maintenance is essential to sustain a functionally healthy population of mitochondria within cells. Proper mtDNA replication and distribution within mitochondrial networks are essential to maintain mitochondrial homeostasis. However, the fundamental basis of mtDNA segregation and distribution within mitochondrial networks is still unclear. To address these questions, we developed an algorithm, Mitomate tracker to unravel the global distribution of nucleoids within mitochondria. Using this tool, we decipher the semi-regular spacing of nucleoids across mitochondrial networks. Furthermore, we show that mitochondrial fission actively regulates mtDNA distribution by controlling the distribution of nucleoids within mitochondrial networks. Specifically, we found that primary cells bearing disease-associated mutations in the fission proteins DRP1 and MYH14 show altered nucleoid distribution, and acute enrichment of enlarged nucleoids near the nucleus. Further analysis suggests that the altered nucleoid distribution observed in the fission mutants is the result of both changes in network structure and nucleoid density. Thus, our study provides novel insights into the role of mitochondria fission in nucleoid distribution and the understanding of diseases caused by fission defects.

PurposeSupply chain fraud is a significant global concern for firms, consumers and governments. Evidence of major fraud events suggests the role of supply chain structures in enabling and facilitating fraud, as they often involve several parties in complicated networks designed to obfuscate the fraud. This paper identifies how the structural characteristics of supply chains can play an important role in enabling, facilitating and preventing fraud.Design/methodology/approachThe research follows a theory elaboration approach. The authors build on structural holes theory in conjunction with a multiple case study research design to identify new concepts and develop propositions regarding the role of network structure on supply chain fraud.FindingsThis research shows how structural holes in a supply chain can create advantages for unscrupulous firms, a role we call tertius fraudans, or the cheating third. This situation is exacerbated by structural ignorance, which refers to the lack of knowledge about structural connections in the network. Both structural holes and structural ignorance can create information gaps that facilitate fraud, and the authors propose solutions to detect and prevent this kind of fraud.Originality/valueThis paper extends structural holes theory into the domain of fraud. Novel concepts including tertius fraudans, structural ignorance and bridge collapse are offered, alongside a series of propositions that can help understand and manage structural supply chain fraud.

Social Network Structure

The purpose of this conceptual article is to develop argumentation of the knowledge assets of a firm as consisting of three constructs, to extend the conventional explicit, tacit dichotomy by including potential knowledge. The article highlights the role of knowledge, which has so far not been utilized in value creation. The underlying assumption in the article is that knowledge assets can be thought of as embedded in the relationships between individuals in the firm, rather than possessed by single actors. The concept of potential knowledge is explained with selected social network and knowledge management literature. The findings suggest that the ideal social network structure for explicit knowledge is centralized, for tacit knowledge it is distributed, and for potential knowledge decentralized. Practically, the article provides a framework for understanding the connection between knowledge assets and social network structures, thus helping managers of firms in designing suitable social network structures for different types of knowledge.

Study Results

Purpose The purpose of this paper is to identify the main factors influencing agri-food small and medium enterprises (SMEs) participation in business networks and to evaluate the impacts of these factors on network structure and the ensuing competitive strategy. Design/methodology/approach The study is articulated in four main steps. First, a critical literature review is conducted concerning the main approaches to firm competitive advantage and the role of stakeholder relationships. Then, three research questions are formulated and discussed in the light of two case studies describing the implementation of an innovative contractual solution in Italy (i.e. business network contracts). Finally, based on these findings, a set of more general “propositions” are stated and included in a provisional conceptual model that schematically depicts an integrated vision of the antecedents and mechanisms influencing SMEs business network structure and competitive strategy. Findings The study results pointed out the opportunity to adopt an integrated approach, combining resource-based view and stakeholder causal scope approaches. The provisional conceptual model proposed illustrates the role of both external and internal resources and relational constructs to shaping network structure and competitive strategy. Originality/value The study’s contribution is twofold. First, the empirical study shed light on opportunities and limits of two business networks with different backgrounds, approaches and outcomes towards value creation. Second, the conceptual framework proposed advances our understanding and knowledge of the factors and mechanisms influencing SMEs business network structure and competitive strategy.
