Abstract

Purpose

The purpose of this paper is to develop a decision tool that enables supply chain (SC) architects to design resilient SC networks (SCNs). Two resilience design determinants are considered: SC density and node criticality. The effect of considering these determinants on network structures is highlighted based on the ability to resist disruptions and how SC performance is affected.

Design/methodology/approach

A mixed-integer non-linear programming model is proposed as a proactive strategy to develop resilient structures; design determinants are formulated and considered as constraints. An upper limit is set for each determinant, and resistance capacity and performance of the developed structures are evaluated. These upper limits are then changed until SC performance stabilizes in case of no disruption.

Findings

Resilient SCN structures are achieved at relatively low design determinants levels on the expense of profit and without experiencing shortage in case of no disruption. This reduction in profit can be minimized on setting counter values for the two determinants; relatively higher SC density with lower node criticality or vice versa. At very low SC density levels, the design model will reduce the number of open facilities largely leading to only one facility open at each echelon; therefore, shortage occurs and vulnerability to disruption increases. On the other hand, at high determinants levels, SC vulnerability also increases as a result of having more geographically clustered structures with higher inbound and outbound flows for each facility.

Originality/value

In this paper, a novel proactive decision tool is adopted to design resilient SCNs. Previous literature used metrics for SC density and node criticality to assess resilience; in this research, determinants are incorporated directly as constraints in the design model. Results give insight to SC architects on how to set determinant values to reach resilient structures with minimum performance loss in case of no disruption.

Abstract

Under the authoritarian rule of Enver Hoxha, Albania pursued one of the more unusual variants of a planned economy, increasingly isolated from the rest of the socialist world. In this chapter, the authors consider the interplay between the Hoxha’s policy of economic isolationism and the economics produced in isolation. Several conclusions can be drawn. First, much like in other authoritarian regimes, economic theory did not drive economic policy; rather political ideology determined policy; economic theories were retroactively constructed and used as justification. Second, authoritarian-decreed economic theory (dogma) meant that the job of Albanian economists was distinctly different from what we observe elsewhere. Albanian economists played two roles – propaganda for regime positions and technical support for regime policies. Third, and most uniquely Albanian, economic and political isolation created an echo-chamber where theory was functionally irrelevant to policy-making or practice. Decreed economic theory was substantively empty, and new ideas were shut out. This had profound implications for Albania’s eventual transition to a market economy.

Abstract

This chapter examines the relationship between finance capital and the transformation of the state in Rudolf Hilferding’s thought. Hilferding defines finance capital as the fusion of banking and industry, a situation that presupposes a high degree of development of capitalist relations. Finance capital prompts a transformation of the state economic functions. This chapter considers the transfor­mation of the state and its consequent ability to deal with crises of finance capital era. It also highlights Hilferding’s pioneering contribution in sketching the bases for the great contemporary theories of State intervention in crises regulation.

Abstract

Purpose

The purpose of this paper is to discuss the literature on concept theory in library and information science (LIS) from an epistemological perspective, ascribing each paper to an epistemological family and discussing their relevance in the context of the knowledge organization (KO) domain.

Design/methodology/approach

This paper adopts a hermeneutic approach for the analysis of the texts that compose the corpus of study following contingency and categorical analyses. More specifically, the paper works with Bardin’s contingency analysis and follows Hjørland’s families of epistemologies for the categorization.

Findings

The analysis corroborates the observations made for the last ten years about the scarcity of studies on concept theory in LIS and KO. However, the study also reveals an epistemological turn on concept theory since 2009 that could be considered a departure from the rationalist views that dominated the field and a continuation of a broader paradigm shift in LIS and KO. All analyzed papers except two follow pragmatist or historicist approaches.

Originality/value

This paper follows-up and systematizes the contributions to the LIS and KO fields on concept theory mainly during the last decade. The epistemological analysis reveals the dominant views in this paradigm shift and the main authors and trends that are present in the LIS literature on concept theory.

Abstract

This paper proposes that narrative inquiry adopt the concept of the “involute” – a passage stored in memory from reading that is later enlisted as a problem-solving device – to further the goal of understanding the identity work performed through reading and writing. Three related examples are given – one from Thomas De Quincey, the nineteenth-century essayist who coined the term and used an involute in fashioning himself as a scholar; one from Jane Addams, who used an involute from De Quincey to separate the role of the social worker from that of the literary critic; and one from the contemporary New Historicist Stephen Greenblatt, who used an involute to create a socially engaged identity for literary researchers. Considering these examples, I argue that involutes offer insights into the connections between selves and others, words and acts, past and present that should advance interdisciplinary study and advocacy of morally responsible discourse.
