The provision of air transport services in small and regional airports is a major concern worldwide as regional aviation is challenged with inadequate revenues. This chapter aims to identify the driving factors for sustaining regional airlines and airports. Nine factors are identified through literature review and expert opinion. Fuzzy-total interpretive structural modeling is used to develop a hierarchical relationship among the factors. Truncated population of the region, national subsidies, and airport infrastructure development have been found to be the strongest drivers for promoting regional airports. This hierarchical model provides a logical structure to the factors.

Prefabricated products are continually entering the building construction market; yet, the decision to use prefabricated products in a construction project is based mostly on personal preferences and the evaluation of direct costs. Researchers and practitioners have debated appropriate measurement systems for evaluating the impacts of prefabricated products and for comparing them with conventional on-site construction practices. The more advanced, cost–benefit approach to evaluating prefabricated products often inspires controversy because it may generate inaccurate results when converting non-monetary effects into costs. As prefabrication may affect multiple organisations and product subsystems, the method used to decide on production methods should consider multiple direct and indirect impacts, including nonmonetary ones. Thus, this study aims to develop a multi-criteria method to evaluate both the monetary and non-monetary impacts of prefabrication solutions to facilitate decision-making on whether to use prefabricated products.

Drawing upon a literature review, this research suggests a multi-criteria method that combines the choosing-by-advantage approach with a cost–benefit analysis. The method was presented for validation in focus group discussions and tested in a case involving a prefabricated bathroom.

The analysis indicates that the method helps a project’s stakeholders communicate about the relative merits of prefabrication and conventional construction while facilitating the final decision of whether to use prefabrication.

This research contributes a method of evaluating the monetary and non-monetary impacts of prefabricated products. The research underlines the need to evaluate the diverse benefits and sacrifices that stakeholder face when considering production methods in construction.

This article explores how the Danish public sector, over time, has followed different temporal strategies in order to extend the present and handle the system's increasing complexity, thereby counteracting a tendency towards entropy. It proposes that historical changes in the public sector's understandings of the concepts of “time” and “change” can be seen as the answer to the sector's enduring problem of ever-increasing complexity.

The authors conduct second-order observations of how the Danish public sector, in the period from 1900 until 2020, observes “time” and “change”. More specifically, they first observe how issues over time are temporalized in different forms, before employing the guiding distinction, operation/temporalization, to analyse the differences between temporalities.

The authors show that, today, the Danish public sector deals with the problems of complexity and entropy through, what is called, potentialization. Potentialization entails operations that aim to increase potentialities, rather than realize possibilities within a given potentiality. It works by extending the present, drawing on a particular temporality which is split into a present present and a future future.

The paper offers managers insights into the implications of their own observations of time and change, including how they might draw on different temporal semantics, through which managerial situations emerge differently. The paper also reveals that issues of transformation are not always about transformation, rather they concern the question of how to handle an increasing internal complexity.

The article shows that potentialization and its temporal semantic of “transformation” also comes with a price – namely that it dissolves the certainties of structures, which results in conflicting expectations.

The paper draws on systems theory, including its notions of time and entropy, to analyse the evolution of public administration and management. It thereby produces a diagnosis of the present which offers insights into contemporary conditions for public management.
