Navigating the unlearning landscape: an organizational unlearning taxonomy and an outcome-centric model

Purpose The purpose of this paper is to explore the phenomenon of organizational unlearning with a focus on challenging path dependence and its implications on the organizational change field. By generating a taxonomy of unlearning definitions and examining the dimensions, actors and processes involved, the authors aim to offer a holistic understanding of organizational unlearning and its potential applications for organizations facing ambiguity and uncertainty. Design/methodology/approach This conceptual paper draws the literature on organizational unlearning to map existing definitions and categorize them into a comprehensive taxonomy to propose a model focused on the outcomes. Findings The findings highlight that organizational unlearning involves the three main organizational dimensions (micro: individuals; meso: groups; macro: organizations) and that the macro-organizational perspective represents the best fit for the concept. Furthermore, the authors’ argue that the most appropriate process for understanding the unlearning phenomenon is through challenge, as it allows the questioning of the present and facilitates critical reflection. Finally, applying organizational unlearning to path dependence concept, the authors’ posit that organizations can overcome negative transfer effects and build new awareness to reinterpret their dependencies in light of environmental changes. Originality/value This study contributes to the literature on organizational unlearning by providing a comprehensive taxonomy of definitions, clarifying the dimensions, constructs and processes involved. The integration of challenging path dependence with organizational unlearning offers a novel perspective on the potential for organizational change field. The paper’s findings have practical implications for organizations striving to survive and develop in uncertain environments.

Between Freedom and Order: Evolution logic of urban-rural population mobility Policy from the perspective of historical institutionalism

Urban-rural population flow is the key element and important driving force for urban-rural integration development and rural revitalization. The pattern of urban-rural population flow in China is restricted and guided by policies. From the perspective of historical institutionalism, this paper analyzes the evolution context, structural logic and dynamic mechanism of the change of urban and rural population mobility policy. The urban and rural population mobility policy has gone through five historical stages: the order reconstruction period at the beginning of the founding of New China, the political call period after the Great Leap Forward Movement, the free flow period after the reform and opening up, the period of making the best use of the situation under the economic system reform and the accelerated integration period under the background of the new era. The institutional choice under different paths, the institutional evolution under the key nodes and the institutional continuation under the path dependence constitute the structural logic of the policy change of urban-rural population mobility. The situation coupling under the action of exogenous variables, the value coupling promoted by the change of ideas, and the subject coupling under the interaction of actors’ game constitute the dynamic mechanism of policy change, which promotes the historical change and realistic development of policy.

A political economy analysis of changes and continuities in Iran–Africa trade relations: a case of South–South dependency?

This paper provides a political economy analysis of the bilateral trade relations and patterns of exchange that existed between Iran and Sub-Saharan Africa (SSA) from 1962 to 2021. The paper contributes to the growing literature on Iran–Africa relations by empirically delineating not just the changes, but also the continuities between Iran and its African trading partners before and after the Iranian Revolution. It also adds nuance to the broader scholarship on South–South cooperation by showing the disparity between the rhetoric of South–South solidarity and reciprocity between Iran and SSA, on one side, and their low and fluctuating trade volumes, on the other. These volumes resulted from historical inertia or path dependency and structural factors, including trade complementarities and geopolitical conditions, more than demographic, cultural, or religious realities. They were also shaped by the agency and decision-making of Iranian and African leaders and officials regarding the extent to economically engage with each other.

Tracking the scaling of urban open spaces in China from 1990 to 2020

Urban open spaces (UOS) are crucial for urban life, offering benefits across individual and societal levels. However, the understanding of the systematic dynamic of UOS scaling with city size and its potential non-linear performance remains a limited clarity area. This study bridges this gap by integrating urban scaling laws with remote sensing data from 1990 to 2020, creating a framework to analyze UOS trends in China. Our findings reveal that UOS growth is sub-linear scaling with city size, exhibiting economies of scale with scaling exponents between 0.55 and 0.65 and suggesting potential shortages. The distribution structure of UOS across cities is becoming increasingly balanced, as indicated by the rising Zipf’s slope from 0.66 to 0.88. Southeastern coastal cities outperform, highlighting spatial variations and path dependency in UOS development. Additionally, using metrics of Scale-adjusted metropolitan indicator (SAMI) and the ratio of open space consumption to population growth rates (OCRPGR), we observe a trend towards more coordinated development between UOS and population, with a declining proportion of uncoordinated cities. Our long-term, large sample coverage study of UOS in China may offer positive significance for urban ecological planning and management in similar rapidly urbanizing countries, contributing to critical insights for quantifying and monitoring urban sustainable development.

Research on a Low-Cost High-Precision Positioning System for Orchard Mowers

To regulate the energy flow in orchard ecosystems and maintain the environment, weeding has become a necessary measure for fruit farmers, and the use of automated mowers can help reduce labor costs and improve the economic efficiency of orchards. However, due to the complexity of the geographic and spatial environment of the orchard, in particular, the loose and undulating road surface, the interference of satellite signals by large trees, etc., which decreases the positioning accuracy and stability of the positioning system of the mower, and the high cost of the sensor also affect the popularization of intelligent mowers for these applications. To address the above problems, this paper constructs a positioning system through a low-cost global navigation satellite system (GNSS), inertial measurement unit (IMU), and odometry, and utilizes the Kalman filter algorithm based on the error state for a combined GNSS/IMU positioning so that the inertial navigation system can maintain a more accurate positioning when the GNSS signals are poor. Considering the side-slip and error accumulation problems of the odometry of the traction mower, the combined GNSS/IMU positioning information is used to optimize the odometry model and improve the navigation and positioning accuracy. To reduce the measurement error of the IMU and the problem of error accumulation, this paper utilizes the nonholonomic constraint (NHC) of a lawn mower to suppress the dispersion of IMU measurement errors and constructs periodic and nonperiodic zero-velocity updating (ZUPT) strategies in combination with the travel paths of lawn mower navigation operations in the region to update the IMU data to improve the positioning accuracy and stability of the positioning system. The experiments show that the average error of the constructed positioning system is controlled within 0.15 m, the maximum error is maintained at approximately 0.3 m, and the positioning system constructed by using low-cost sensors can achieve a positioning accuracy similar to that of the differential global navigation satellite system (DGNSS), which is beneficial for the promotion and application of intelligent mowers in orchards.

Can Digital Finance Enable China’s Industrial Carbon Unlocking under Environmental Regulatory Constraints? Joint Tests of Regression Analysis and Qualitative Comparative Analysis

Sustainable development goals challenge the carbon lock-in dilemma of the industrial economy, and identifying the motivation and mechanism behind carbon unlocking has become an urgent priority. With its inclusive and precise advantages, digital finance (DF) provides a new impetus for the economy’s low-carbon transformation, while reasonable environmental regulation (ER) acts as an important guiding constraint. We focus on the carbon unlocking performance of DF under ER constraints. After constructing and calculating the industrial carbon unlocking efficiency (ICUE), we observe the trends of ICUE fluctuating positively, clustering towards the eastern region, and polarization. Subsequently, based on theoretical analyses, we explore the marginal and configuration effects of DF and ER in improving ICUE using panel data from 30 Chinese provinces between 2011 and 2021 and adopt a mixed research method with regression analysis (Tobit hierarchical regression and quantile regression for panel data (QRPD)) and dynamic fuzzy-set qualitative comparative analysis (fsQCA). The regression analysis results show that DF can notably enhance China’s provincial ICUE, with ER generally serving as a positive moderator; however, the unlocking potential of informal environmental regulations needs further exploration. As ICUE improves in a specific location or time, the positive contribution of DF to ICUE also increases, whereas the moderating effect of ER exhibits an optimal range and follows an inverted U-shape. The dynamic fsQCA results support the findings of the regression analysis and further emphasize that effective cooperation between DF and ER is crucial for high ICUE, while inadequate DF support and the absence of formal environmental regulations remain bottlenecks in industrial carbon lock-in. Moreover, configuration paths demonstrate clear path dependency in both time and space, indicating a prolonged unlocking endeavor.

Noether’s Theorem of Herglotz Type for Fractional Lagrange System with Nonholonomic Constraints

This research aims to investigate the Noether symmetry and conserved quantity for the fractional Lagrange system with nonholonomic constraints, which are based on the Herglotz principle. Firstly, the fractional-order Herglotz principle is given, and the Herglotz-type fractional-order differential equations of motion for the fractional Lagrange system with nonholonomic constraints are derived. Secondly, by introducing infinitesimal generating functions of space and time, the Noether symmetry of the Herglotz type is defined, along with its criteria, and the conserved quantity of the Herglotz type is given. Finally, to demonstrate how to use this method, two examples are provided.

Adaptive output feedback stabilisation control for cascaded systems with output constraints and disturbance

The system under consideration is a cascaded system composed of integral input-to-state stable inverse dynamics and a non-holonomic system. An adaptive output feedback stabilisation control is proposed for the system with disturbance and output constraints. The dynamic uncertainty is eliminated using the technique that changes the supply rate. An extended state observer is proposed by defining the non-vanishing disturbance as a new state variable of the system. The asymmetric time-varying output constraint is solved by utilising the tan-type barrier Lyapunov function. The result shows that the adaptive output feedback controller guarantees the stability of the closed-loop system without violating the asymmetric time-varying output constraints under the backstepping technique. Simulation results are given to verify the effectiveness of the control method.

Youth labour markets in the Southern European Union, 2009-2021: deciphering trajectories of resilience through a decade of consecutive crises

ABSTRACT This paper adopts a Geographical Political Economy perspective to critically investigate how successive economic crises occurring from 2009 onwards (including the COVID-19 pandemic) affected youth labour markets in Greece, Italy, and Spain. To do so, it first calculates a Resilience Index for three youth employment types (total, part-time, and temporary employment). It then employs Shift-Share Analysis to quantify the effect of national trends, sectoral dynamism, and local characteristics upon total youth employment changes. After identifying those regions that have exhibited resilience or lack thereof and the underlying reasons for their trajectories, the paper outlines a typology of regional youth labour markets’ resilience and examines their dynamics. Specifically, the paper examines the effect of path dependencies, structural deficiencies, and labour polarization on resilience outcomes, concluding that each has steered in different ways the regional youth labour markets examined towards either bouncing back shortly after recessive shocks or developing mechanisms of adaptation amidst recession. Closing, the paper discusses the role of work flexibilization in shaping resilience, finding that whilst it may contribute to coping/adaptation capacities under certain conditions it does not guarantee them.

Upwind Despite Headwind? Degrowth Transformations Amidst Shrinkage and Eroding Democracy in an East German Small Town

Spatial transformation follows the logic of a growth-oriented economy that values cities according to their place in the chain of capitalist wealth production. Many cities in East Germany have lost their significance as sites of production and are consequently facing population decline and the weakening of social bonds in the community. For this reason, citizens of the East German small town of Zella-Mehlis (state of Thuringia) have begun to reflect on alternative models for urban development. In this article, the process of arriving at a degrowth strategy, as provided by the academic discourse, will be documented. It will be demonstrated that the process of shrinkage has not only left little space for a degrowth planning approach put into practice. Moreover, the article reveals that the costs of the growth economy on society are not limited to population shrinkage, but also have a severe impact on the sociability of the local community. The rise of right-wing populists and climate change-denying actors mirrors the decreasing social ability for collective learning processes needed for a shift to a solidary degrowth strategy. However, the case study shows how ambivalent these developments are: Long-term participatory processes within the public–civic partnership framework of the Aufwind (German for upwind) initiative in Zella-Mehlis can challenge path dependencies and open new degrowth-inspired perspectives. The article is informed by many years of intensive field research in a qualitative mixed-method design and focuses on the close links between shrinkage processes, the local degrowth agenda, and the consequences of an eroding democracy.

Aquathermal effect of anomalous pressure generation in consolidating minefill

Recycling cement-amended tailings into subsurface cavities has delivered competitive socioeconomic revenue for underground mining. However, recent instances of anomalous thermal pressure in consolidating backfill have raised growing concerns over the current design philosophy. This study demonstrates that the excellent hydraulic sealing and considerable chemical energy inherent in cemented backfill can spontaneously generate substantial thermal pressurization through constrained pore-fluid expansion. An analytical solution is hence developed for characterizing the non-isothermal behaviour of hydrating backfill based on classical thermo-poroelasticity. The influence of preparation condition and mix design on the pressure evolution in time domain and during spontaneous heat generation is then thoroughly examined, successfully pinpointing the causal mechanism responsible for typical thermal pressure anomalies. It is demonstrated that the anomalous pressure is attributable to both the conservative binder usage, which increases the intrinsic heat load, and the elevated initial temperature, which promotes water volume expansion. The fundamental influence of temperature-sensitive water expansivity on the path dependence of thermal pressurization is also elucidated. This study thus contributes to a comprehensive understanding of the thermally correlated pressure anomalies that frequently occur in field operations. These critical findings would also hold practical implications for designing successful backfill solutions in challenging mine environments.

Understanding land take by low-density residential areas: An institutionalist perspective on local planning authorities, developers and households

Using a case study design, the study focuses on identifying the institutional configuration that determines land take by low-density residential areas. Methodologically, it combines geospatial approaches and new institutionalism to capture and understand residential development, taking into account the interests, constraints and agency of local planning authorities, developers and households. The geospatial analysis shows that land take in the case study regions is primarily the result of low-density residential areas. We find that the combination of rural housing ideals, municipal policy objectives, municipalities' disengagement from spatial development and private sector interests are the main drivers for this kind of residential development. As the interests and constraints apply to all case study regions, the identified institutional configuration has high power in explaining low-density residential development. Our study thus uncovers a close link between the interests and constraints of actors, which on the one hand explains the limited impact of existing and new planning instruments on reducing land take, and on the other hand fosters path dependency in the development of low-density residential areas. Although there is some potential for change, breaking path dependency requires significant behavioural change among local planning authorities, developers and households.

Environmental antecedents, innovation experience, and officials’ innovation willingness: evidence from China

ABSTRACT Prompting officials’ innovation willingness is a prerequisite for processes of public sector innovation. This article constructs a framework explaining officials’ innovation willingness by linking environmental antecedents and path dependence. The empirical analysis, based on an original survey of 403 officials and interviews with 102 officials in China, shows that their innovation willingness is mostly driven by factors within the bureaucratic system, i.e. top-down and horizontal drivers but less so by bottom-up drivers. Moreover, officials with previous innovation experience tend to have more innovation willingness but are less driven by top-down factors. This study advances the theory of innovation willingness generation.

The evolution of the debt—equity doctrine in the light of financial instruments’ digitalization

The article outlines the basics for using the debt—equity dichotomy in the financial instruments typology and analyzes the contradictions and short-comings of the existing approach to classification. It is shown that the “trap” of the debt—equity dichotomy comes from the path dependence process, mainly formed by the inertia of the tax system. It is noted that the applying of the debt—equity dichotomy entails a formalist approach to classification, which does not bring closer to the clarity of the delimitation of contracts according to the criteria of risk and reward distribution, and restrictions on post-contractual opportunism. Arguments are given to explain why the foundations of the debt— equity doctrine may be weakened in relation to crypto assets. This is supported by the fact that the genesis of digital assets occurs in a specific technological context, which determines its own criteria and framework for the typology of instruments. Another set of arguments comes from the fact that the world of crypto assets appears to be coherent with the specific environment of venture capital investment. This environment, in turn, arouses the demand for overcoming the debt—equity dichotomy to implement the tasks of risky investors and structuring the relations of the parties involved in projects. This demand has now led to the emergence of a number of instruments that cannot be classified as either debt or equity, including those using the construct of tokens or contractual agreements used by crowdfunding platforms. Overall, the intellectual effort that previously satisfactorily explained companies’ choices of financing styles and modes is now insufficient to reconcile capital structure theories with the practice of digital asset financing.

Actors and structures in international relations. The US, the EU, and West Africa: from indifference and development to promotion of security

ABSTRACT It is an old debate in social science, what is most influential, actors or structures? The paper resumes the discussion by concretely asking, how can the radical policy shift towards West Africa in the wake of the terrorist attacks on the US in September 11, 2001, be explained by applying an agency-structure approach? The article applies a theoretical framework combining neo-classical realist thinking with the reasoning found in historical institutionalism. Concepts like path dependency and critical juncture are helpful. The roles and priorities of the core foreign policy actors in the United States and in the European Union are discussed before the article identifies international and domestic structures that might constrain the role and influence of the relevant foreign policy decision-makers. It is concluded that neither international nor domestic structures represented strong obstacles to the foreign policy decision makers’ ambitions to implement radical policy changes towards West Africa.

Assembling intelligence in United Nations peacekeeping: between transformation and path dependency

Abstract This article traces the evolution of intelligence in United Nations peacekeeping through a practice-based assemblage lens. We address a gap in the literature by transcending the focus on ‘peacekeeping intelligence’ as merely an evolving policy instrument. Instead, we employ an ‘analytic of assemblage’ that reveals the intrinsic ambiguity of both the concept of peacekeeping intelligence, and the related competing perspectives as well as forms of expertise among stakeholders. We select the United Nations Operation in the Congo (ONUC, 1960–1964), the United Nations Stabilization Mission in Haiti (MINUSTAH, 2004–2017), and the United Nations Multidimensional Integrated Stabilization Mission in Mali (MINUSMA, 2013–2023) as cases to reconstruct the historical evolution of intelligence within peacekeeping. Our analysis reveals profound tensions between efforts to transform intelligence for broader goals like the protection of civilians, on the one hand, and the persistent dominance of military knowledge and tactical priorities in its implementation, on the other. We convey the enduring predominance of military priorities shaping intelligence practices across spatio-temporal contexts, grounded in historical legacies of doctrinal developments, training and regional collaborations. The analysis thereby highlights the interplay between contingency and the influence of enduring power structures in shaping the evolving peacekeeping assemblage. This offers a perspective that links assemblage approaches with the analysis of not only emergence but also path dependency influenced by historical and geopolitical contexts and suggests that strengthening such analytical link holds wider potential for advancing contributions of assemblage approaches to critical security studies.

Challenges in assessing and managing multi-hazard risks: A European stakeholders perspective

The latest evidence suggests that multi-hazards and their interrelationships (e.g., triggering, compound, and consecutive hazards) are becoming more frequent across Europe, underlying a need for resilience building by moving from single-hazard-focused to multi-hazard risk assessment and management. Although significant advancements were made in our understanding of these events, mainstream practice is still focused on risks due to single hazards (e.g., flooding, earthquakes, droughts), with a limited understanding of the stakeholder needs on the ground. To overcome this limitation, this paper sets out to understand the challenges for moving towards multi-hazard risk management through the perspective of European stakeholders. Based on five workshops across different European pilots (Danube Region, Veneto Region, Scandinavia, North Sea, and Canary Islands) and an expert workshop, we identify five prime challenges: i) governance, ii) knowledge of multi-hazards and multi-risks, iii) existing approaches to disaster risk management, iv) translation of science to policy and practice, and v) lack of data. These challenges are inherently linked and cannot be tackled in isolation with path dependency posing a significant hurdle in transitioning from single- to multi-hazard risk management. Going forward, we identify promising approaches for overcoming some of the challenges, including emerging approaches for multi-hazard characterisation, a common understanding of terminology, and a comprehensive framework for guiding multi-hazard risk assessment and management. We argue for a need to think beyond natural hazards and include other threats in creating a comprehensive overview of multi-hazard risks, as well as promoting thinking of multi-hazard risk reduction in the context of larger development goals.

The natural resource management in Nunavut and Greenland – a perspective through historical institutionalism

ABSTRACT This article compares the self-government system in Greenland in Denmark and territorial governance in Nunavut, Canada in relation to the management of natural resources through the perspective of historical institutionalism. Both territories have undergone processes of re-empowerment, and possess major assets of natural resources, and the struggle for self-determination has triggered their metropolitan states (Denmark and Finland) and regional governments to consider some form of self-government. However, two different solutions have appeared due to gradual development through path dependency as legislation and form of government. Nunavut is a territory within the Canadian federal construction, based on Indigenous claims, while Greenland is a self-governing territory within the Danish unitary state. The land claims in Canada have given Nunavut some influence in the management of its natural resources, while Greenland has taken control of its subterranean resources through extended self-government implemented in 2009. This article will highlight the resource policy similarities and differences of the two territories via three potential explanatory factors: historical background, self-government, and the management of natural resources as a point of departure. The findings show that both regions have similarities in historical background and the management of natural resources, but there are also significant differences in how local authorities have addressed mining projects.
