Timber Roof Structures

PurposeThe purpose of this paper is to illustrate the assets of a preventive conservation approach for historical timber roof structures, as a means to improve the quality and durability of maintenance and repair interventions.Design/methodology/approachThe advantages of a preventive approach for historical structures were identified based on two analyses: a study of the structures’ behaviour and an investigation of existing approaches in current practice. The two main identified advantages of the approach, the cyclic process-approach and the potential of knowledge enhancement, were hereafter conceptually implemented in existing approaches.FindingsCurrent practices focus on single curative interventions, and monitoring is often considered redundant. The importance of monitoring and knowledge enhancement is demonstrated based on the theory of complex adaptive systems (CAS). A preventive conservation approach for historic timber roof structures allows integrating these insights.Research limitations/implicationsThe analysis of current practice is a sample survey, and the proposed preventive conservation approach is presented at a conceptual level. Future research foresees a more elaborated study of current practice and detailed validation of the developed approach.Originality/valueThree new contributions to the existing research on preventive conservation are: arguments for the implementation of a preventive approach, based on an analysis of the structures’ behaviour; the identification of limitations of current approaches that can be tackled in a preventive conservation approach; and the integration of the existing international guidelines and the principles of preventive conservation into a conceptual approach for the monitoring and management of these structures. Furthermore, the research paper demonstrates how timber structures can be understood as CAS, which is a novel viewpoint.

Resource Sustainability

Purpose In response to calls for conceptual frameworks and generic theory building toward the advancement of sustainability in supply chain resource utilization and management, the purpose of this paper is to advance a circular framework for supply chain resource sustainability (SCRS), and a decision-support methodology for assessing SCRS against the backdrop of five foundational premises (FPs) deduced from the literature on resource sustainability. Design/methodology/approach Taking a conceptual theory-building approach, the paper advances a set of SCRS decision-support criteria for each of the theoretical premises advanced, and applies the theory of constraints to illustrate the conceptual and practical applications of the framework in SCRS decision making. Findings This study uses recent conceptualizations of supply chains as “complex adaptive systems” to provide a robust and novel frame and a set of decision rules with which to assess the interconnectedness of environmental, economic, and social capital of supply chain resources from pre-production to post-production. Research limitations/implications The paper contributes to theory building in sustainability research, and the SCRS decision framework developed could be applied in tandem with existing quantitative hybrid life-cycle and input-output approaches to facilitate targeted resource sustainability assessments, with implications for research and practice. Originality/value The novel SCRS framework proposed serves as a template for evaluating SCRS and provides a decision-support methodology for assessing SCRS against the five theorized FPs.

The Relationship

PurposeThe authors explore complex adaptive systems (CAS) theory as an updated theoretical perspective for managing product returns that better matches the chaotic nature of recent consumer behaviors. CAS theory highlights the importance of agents who create and self-organize to help systems adapt in unpredictable environments.Design/methodology/approachThis research utilizes data collected from return managers in an online survey and applies regression analyses to estimate the influence of the focal variables.FindingsEmpirical evidence of the firm flexibility–firm adaptability link is established, and return processor creativity positively relates to this link. The firm flexibility–firm adaptability link fully mediates the relationship between return processor creativity and returns management performance and partially mediates the relationship between return processor creativity and relationship quality. Nonmediated effects were observed for turnover and revenue size.Practical implicationsManagers of returns who embrace an adaptability approach become facilitators of returns by supporting processor creativity. Enhancing the autonomy of processors in their day-to-day work increases the knowledge-creation capabilities of the firm, which helps the firm move forward and adapt in an uncertain environment.Originality/valueThis research presents empirical evidence of the underlying mechanisms of CAS theory in the product returns context by studying processor agents and argues that CAS theory better fits the current dynamics of the product returns environment. Further, this paper extends work by Espinosa et al. (2019) and Nilsson (2019) by studying how a specific human characteristic – creativity – impacts product returns management.

PurposeThe purpose of this conceptual paper is to explore the role of strategic leadership under conditions of uncertainty and unpredictability. The authors argue that highly improbable, but high-impact events require the upper echelons of management, traditionally the custodians of strategy formulation to offer a new kind of strategic leadership focused on new mindsets, organizational capabilities, more in tune with high uncertainty and unpredictability.Design/methodology/approachDrawing on strategic leadership, and complexity leadership theory, the authors review the literature and present a conceptual framework for exploring the nature of strategic leadership under uncertainty. The authors conceptualize organizations as complex adaptive systems and discuss the imperatives for developing new mental models for emergent leadership.FindingsStrategic leaders have a key role to play in preparing their organizations for episodic disruptions. These include developing their adaptive capabilities and building resilient organizations to ensure their organizations cannot only bounce back after a disruption but have the capacity for transformation to new fitness levels when necessary. Strategic leaders must engage with complexity leadership by seeing their organizations as complex adaptive systems, reconfigure their leadership approaches and organizations to build strategic adaptive capability.Research limitations/implicationsThis is a conceptual paper and the authors cannot make any claims of causality.Practical implicationsOrganizational leaders need to reconfigure their mental models and leadership approaches to reflect the new normal of uncertainty and unpredictability. Developing the strategic adaptive capability of organizations should prepare them for dealing with high impact events. To assure business continuity in the face of disruptions requires building flexible, adaptable business models.Originality/valueThe paper focuses on how managers can offer strategic leadership for a new normal that challenges some of our most cherished leadership and strategic management paradigms. The authors explore the new mental models and leadership models in an era of great uncertainty.

Purpose Smallholder value chains are dynamic, changing over time in sudden, unpredictable ways as they adapt to shocks. Understanding these dynamics and adaptation is essential for these chains to remain competitive in turbulent markets. Many guides to value chain development, though they focus welcome attention on snapshots of current structure and performance, pay limited attention to the dynamic forces affecting these chains or to adaptation. The paper aims to discuss these issues. Design/methodology/approach This paper develops an expanded conceptual framework to understand value chain performance based on the theory of complex adaptive systems. The framework combines seven common properties of complex systems: time, uncertainty, sensitivity to initial conditions, endogenous shocks, sudden change, interacting agents and adaptation. Findings The authors outline how the framework can be used to ask new research questions and analyze case studies in order to improve our understanding of the development of smallholder value chains and their capacity for adaptation. Research limitations/implications The framework highlights the need for greater attention to value chain dynamics. Originality/value The framework offers a new perspective on the dynamics of smallholder value chains.

PurposeThis paper aims to examine how government continuity planning contributes to strengthening the public sector's emergency preparedness, resulting in enhanced resilience of the public sector. Government continuity plans (GCPs) are a recently focused concept in disaster preparedness, compared to business continuity plans (BCPs) in the private sector. The need for BCPs was widely recognized after the 2011 Great East Japan Earthquake (GEJE) and the 2011 Thailand Floods. However, recent disasters, such as the 2016 Kumamoto Earthquake in Japan, have revealed that local governments without effective GCPs were severely affected by disasters, preventing them from quickly responding to or recovering from disasters. When the GEJE occurred in 2011, only 11% of municipal governments in Japan had GCPs.Design/methodology/approachThe paper analyzes basic principles of government continuity planning using complex adaptive systems (CAS) theory while summarizing recent developments in theory and practice of government continuity planning.FindingsThis research investigates the Japanese experience of GCPs using self-organization, one of the concepts of CAS. A GCP will complement regional disaster plans, which often focus on what governments should do to protect citizens during emergencies but fail to outline how governments should prepare for an emergency operation. The study concludes that GCPs contribute to increased resilience among the public sector in terms of robustness, redundancy, resourcefulness and rapidity.Practical implicationsThis paper includes implications for the development and improvement of a GCP's operational guideline.Originality/valueThis research fulfills an identified need to investigate the effectiveness of a GCP for resilience in the public sector and how to improve its operation using concepts of CAS.

Purpose The purpose of this paper is to investigate the decision-making process in the management of the complex adaptive systems (CAS), particularly focusing on the dimensions that affect the individual decision maker (DM) when passing from decision to behavior in fitting processes. Although the importance of the general process of fitting in terms of organizational design has been highlighted in earlier studies, a closer focus on the DM perspective is required. Design/methodology/approach Starting from the theoretical frameworks of viable systems approach (vSa) and addressing the evolving concepts of change and adaptation in CAS, the work takes the DM perspective and investigates the dimensions involved in the paths that lead complex decisions into behaviors, when referring to fitting processes. The paper reviews the vSa and the concept of CAS, deepening the decision making in fitting processes. Then, the paper proceeds to discuss the schemes and the categories that affect, at different levels, the decision and behavioral choices by proposing an interpretative framework. Findings The paper proposes a general framework useful to recognize/identify which are the elements/dimensions that have to be considered when organizations change in pursuing survival. The findings of the paper also show how adopting a vSa as a meta-model can be insightful to the understanding of service systems and useful in fully comprehending decision-making processes and behavior in complex adaptive system. Originality/value The originality of this paper lies in exploring the decision making process in CAS, adopting a closer perspective on the single DM through the lens of the vSa.

Purpose Building on the complex adaptive systems (CAS) framework, this paper aims to investigate the detrimental effect of virtual teams’ (VTs) challenges and the upholding role of trust on the members’ ratings of VTs’ performance. Also, the study examines the mediating role of the preferences for VTs and investigates the moderating function of the openness to experience personality trait on the relationship between challenges, trust and preference for VTs. Design/methodology/approach Cross-sectional survey data were collected from a sample of 498 university students in Romania and path analysis was used for data analysis. Findings The results show evidence of the harmful effect of VTs’ challenges on members’ ratings of VTs’ performance and reveal that trust boosts members’ ratings of VTs’ performance. The findings highlight the mediating role of members’ preference for VTs and show evidence that the openness to experience personality trait strengthens the negative effect of the challenges on members’ preference for VTs. Research limitations/implications Given the cross-sectional design of the study, inferences regarding the causal relationship between the variables cannot be made, and further longitudinal research is called for. Originality/value The study builds on the CAS framework and addresses the call for research to explore the variables that might contribute or impede VTs’ performance.

Viable System

PurposeComplex systems adapt to survive, but little comparative literature exists on various approaches. Adaptive complex systems are generic, this referring to propositions concerning their bounded instability, adaptability and viability. Two classes of adaptive complex system theories exist: hard and soft. Hard complexity theories include Complex Adaptive Systems (CAS) and Viability Theory, and softer theories, which we refer to as Viable Systems Theories (VSTs), that includes Management Cybernetics at one extreme and Humanism at the other. This paper has a dual purpose distributed across two parts. In part 1 the purpose was to identify the conditions for the complementarity of the two classes of theory. In part 2 the two the purpose is to explore (in part using Agency Theory) the two classes of theory and their proposed complexity continuum.Design/methodology/approachExplanation is provided for the anticipation of behaviour cross-disciplinary fields of theory dealing with adaptive complex systems. A comparative exploration of the theories is undertaken to elicit concepts relevant to a complexity continuum. These explain how agency behaviour can be anticipated under uncertainty. Also included is a philosophical exploration of the complexity continuum, expressing it in terms of a graduated set of philosophical positions that are differentiated in terms of objects and subjects. These are then related to hard and softer theories in the continuum. Agency theory is then introduced as a framework able to comparatively connect the theories on this continuum, from theories of complexity to viable system theories, and how harmony theories can develop.FindingsAnticipation is explained in terms of an agency’s meso-space occupied by a regulatory framework, and it is shown that hard and softer theory are equivalent in this. From a philosophical perspective, the hard-soft continuum is definable in terms of objectivity and subjectivity, but there are equivalences to the external and internal worlds of an agency. A fifth philosophical position of critical realism is shown to be representative of harmony theory in which internal and external worlds can be related. Agency theory is also shown to be able to operate as a harmony paradigm, as it can explore external behaviour of an agent using a hard theory perspective together with an agent’s internal cultural and cognitive-affect causes.Originality/valueThere are very few comparative explorations of the relationship between hard and soft approaches in the field of complexity and even fewer that draw in the notion of harmony. There is also little pragmatic illustration of a harmony paradigm in action within the context of complexity.

The Right

Purpose – Businesses are always seeking resilient strategies so they can weather unpredictable competitive environments. One source of unpredictability is the unsustainability of commerce's environmental, economic or social impacts and the limitations this places on businesses. Another is poor resilience causing erroneous and unexpected outputs. Companies prospering long-term must have both resilience and sustainability, existing in a symbiotic state. The purpose of this paper is to explore the two concepts and their relationship, their combined benefits and propose an approach for supporting decision makers to proactively build both characteristics. Design/methodology/approach – The paper looks at businesses as complex adaptive systems, how their resilience and sustainability can be defined and how these might be exhibited. It then explores how they can be combined in practice. Findings – The two qualities are related but have different purposes, moreover resilience has two major forms related to timescales. Both kinds of resilience are identified as key for delivering sustainability, yet the reverse is also found to be true. Both are needed to deliver either and to let businesses flourish. Practical implications – Although the ideal state of resilient sustainability is difficult to define or achieve, pragmatic ways exist to deliver the right direction of change in organisational decisions. A novel approach to this is explored based on transition engineering and robustness engineering. Originality/value – This paper links resilience and sustainability explicitly and develops a holistic pragmatic approach for working through their implications in strategic decision making.

The Impact

Purpose – Following a bacterial-based modeling approach, the authors want to model and analyze the impact of both decentralization and heterogeneity on group behavior and collective learning. The paper aims to discuss these issues. Design/methodology/approach – Inspired by bacterial conjugation, the authors have defined an artificial society in which agents’ strategies adapt to changes in resources location, allowing migration, and survival in a dynamic sugarscape-like scenario. To study the impact of these variables the authors have simulated a scenario in which resources are limited and localized. The authors also have defined three constraints in genetic information processing (inhibition of plasmid conjugation, inhibition of plasmid reproduction and inhibition of plasmid mutation). Findings – The results affirmed the hypothesis that efficiency of group adaptation to dynamic environments is better when societies are varied and distributed than when they are homogeneous and centralized. Originality/value – The authors have demonstrated that in a model based on free interactions among autonomous agents, optimal results emerge by incrementing heterogeneity levels and decentralization of communication structures, leading to a global adaptation of the system. This organic approach to model peer-to-peer dynamics in complex adaptive systems (CAS) is what the authors have named “bacterial-based algorithms” because agents exchange strategic information in the same way that bacteria use conjugation and share genome.
