Most often, the contemporary supply chains are nowadays analyzed from the perspective of triadic arrangements, which brings an understanding of the complexity and dynamics of changes in inter-organizational structures. In this paper, the structural hole and closure as two basic forms of triads are depicted to elaborate on the emergence of network rent in supply chains, as the uneven distribution of network rent derived from the inter-organizational structures is still a vital issue. The goal of this paper is thus to identify and explain the phenomenon of network rent appropriation in triadic supply chains. Likewise, the paper seeks to recognize the possibility of estimating network rent in supply chains.

Due to the new purchasing trends, omnichannels in the product distribution are exposed to dynamic changes. One of such changes is the digital transformation, which affects not only the way the purchases are made, but also transport, collection of products by customers and management of product returns. Oftentimes, these activities are transferred to the virtual world, and they are performed with the use of innovative technology. The aim of this paper is to present the use of in-store and out-store technologies in the omnichannel structure from the perspective of new emerging purchasing trends.

One of the key prerequisites for establishing the network connections in a supply chain is the focus of primary members on core competencies and outsourcing remaining services to the service providers. As a result, the multiple relationships with several actors are established. In the literature, to illustrate the network relationships in a supply chain, the concept of transitive triads has been often employed. Nonetheless, this framework is rather static, as it does not derive the real dynamics of forming the network relationship in the light of the social capital theory for which the concept of triad is a key issue. The paper aims to reveal and describe the stages of forming the network relationships in a supply chain with the use of transitive service triad. The transitive triad encompasses three actors that establish the dyadic relationships between one another. As a result, the transitive triad is formed by three dyadic arrangements.

Supply chains are complex structures full of paradoxes that can be understood in different ways.
Thus, many concepts related to supply chain formation and operation originate from specific
metaphors. Some of them lead to well-known ways of thinking, whereas others contribute to the
development of new ideas and interpretations of supply chain. Certain metaphors may refer to an
entire organization, while others may emphasize one of its components, or concern a specific
operational aspect. Metaphors may also be a useful instrument for learning about complex and
multi-dimensional problems of resilient supply chain, i.e. supply chain that maintains operational
continuity thanks to its ability to handle uncertainty, and thus is characterised by the capability of
achieving a new status in consequence of disruptions.
The paper attempts to identify the operational mechanism of resilient supply chain, using the multi-
metaphor approach. For this purpose, metaphors characteristic for the neopositivist paradigm were
applied. Following the summary, the paper depicts the interpretative fields of resilient supply chains,
the role of metaphors in explaining the organizational reality, and then explains particular elements
of reality of a resilient supply chain through the metaphor of organization as an organism, flux and
transformation, dissipative structure and brain.

The network view can be successfully employed while investigating the role of relationships in deriving the competitive advantage of contemporary supply chains. Prior studies, when elaborating on the competitive advantage of supply chains, are mostly anchored in either the resource-based view or the dyadic view, as two complementary, but distinct concepts.

Consequently, there is a dearth of studies that elaborate on the concept of network competitive advantage as the extension of relational view. To address this gap, this study aims to combine the network view of competitive advantage with embeddedness as an important dimension of the social capital. In this study, the concept of structural and relational embeddedness has been employed to offer a systematic conceptual analysis of the network competitive advantages of triadic supply chains. Based on this conceptual reasoning, we then build key theoretical propositions that aid in deeper understanding of how the relationships are shaped by the social capital to derive the network competitive advantage of supply chains.
