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.

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.

Family Management and Historical Origins: The Italian Experience

ABSTRACTResearch Question/IssueThe purpose of this paper is to analyze the long‐run determinants of the corporate structure of Italian firms to explain the persistent role of a long‐run tradition of civic capital that has favored interpersonal trust, fostered cooperation outside of the narrow ties of family members and limited the diffusion of family businesses managed predominantly by family members.Research Findings/InsightsWe examined a large sample of Italian listed and not listed firms and identified those that operate in current municipalities that in the past used to be independent communes. Such firms featuring experiences of civic engagement are today less likely to be owned by a family and run by family management.Theoretical/Academic ImplicationsOur findings highlight the role of institutions as drivers of corporate governance and signal that long forgotten institutions, by modifying local social capital, may interact with family social capital and have important persistent effects on current corporate governance arrangements. Therefore, significant elements of path dependency may explain current patterns of unbundling of ownership and management.Practitioner/Policy ImplicationsPersistent corporate governance structures are difficult even for policymakers to modify. Our findings suggest that political measures should favor the accumulation of social capital at the local level when aiming to change ownership and management arrangements and limit the misallocation of resources due to family management.

History Matters: The Institutionalization and Innovation Paradox in the Judiciary

The judiciary is a field lacking research in relation to its administration and innovation; however, different theoretical perspectives can be followed. This work reviews this trend while adding to it. An institutional perspective is presented, as is its explanatory potential. This perspective captures the context of the public sector; however, when analyzing its interpretation in terms of innovation, it is revealed to be doubly paradoxical. From the theoretical point of view, institutionalization focuses on the maintenance of processes, while innovation, gradually or abruptly, investigates their disruptions. Nevertheless, institutionalization can be observed as part of the sedimentation of innovation. Institutionalization is presented, in the context of innovation, as a selection mechanism that shapes such innovation. This paradox is presented under the review of organizational institutionalism vis-à-vis innovation and, for its unfolding, considers the adoption of innovation as an adaptation to the prevalent rationalized elements. This presentation is paralleled with the interpretation that innovation is limited by a structure that, sometimes rationalized, forms its trajectory. Considering the social function of the judiciary that is anchored in institutionalism, historical institutionalism is thus added, centrally placing the judiciary in the current institutional matrix and associating its path dependence with the dimensions of its innovation. Based on these outlines, propositions and a suggested agenda for future research are presented.

Policy Capacity for Urban Village Redevelopment in China: A Two-Case Case Study

Policy capacity is described as a determinant for effective policy implementation. Its contents vary according to modes of governance. Based on available academic studies, grey literature, and semi-structured interviews, this study empirically explores how urban village redevelopment has been carried out in two cities, Hangzhou and Guangzhou, through the lens of policy capacity. By contrasting policy outcomes and the manifestation of policy capacity at different levels in these two cities, we develop three arguments that contribute to our understanding of urban renewal and policy capacity. Firstly, the performance of any policy action is affected by the capacity of the central actor to develop and implement policies. Secondly, understanding the interactive logical between analytical, operational, and political capacities under different governance modes is the key to understanding the strengths and weaknesses of policy capacity in a specific sector. Shaped by local contexts and past experience, local governments are predisposed to path dependence in developing and deploying policy capacity in urban village redevelopment. Thirdly, the capabilities and resources needed to support policies are largely determined by policy problematization at the analytical level: the technique-based approach of policy capacity theory needs to complete the missing link between policy framing and ethical issues.

A variational approach to deriving Hamiltonian functions under non-holonomic constraints — the case of the Gaussian thermostats

The Hamiltonian function (H), if it exists, provides a powerful platform for studying the dynamics of constrained many-particle systems. For systems under holonomic constraints, H can be derived from the principle of least action (PLA) formulated in terms of a suitable set of generalized coordinates. In molecular dynamics (MD) simulations, where the system temperature often prescribes a non-holonomic constraint, the challenge is to find the system’s Hamiltonian. The Gaussian Isokinetic (GIK) thermostat, the first deterministic physics-preserving thermostat in MD, was derived from the principle of least constraint (PLC) in the early 1980s: its H, interestingly, was discovered almost 15 years later. A mathematically rigorous connection of the GIK Hamiltonian with PLA, however, has been missing until now. In this article, we adopt a variational approach to establish the equivalence of PLC with PLA for a class of non-holonomically constrained many-particle systems, and present the general formulation of the Euler–Lagrange equations of motion through time rescaling. Making use of the particular forms of the Lagrange multiplier obtained from the principle of least constraint, we derive H for the GIK and the Gaussian Isoenergetic thermostats.

Human resources in dentistry geographical distribution in Brazil and Colombia: Comparative analysis from the perspective of historical institutionalism

The Human Resource in Health constitutes one of the six core components of health systems, playing a crucial role in realizing the right to health and ensuring access and service quality. Additionally, institutional frameworks within each country, encompassing laws, decrees, political systems, and health system characteristics, exert a significant influence on HRH and, specifically, in Human Resources in Dentistry (HRD). Both Brazil and Colombia experienced neoliberal reforms in the 1990s, introducing new institutions within the existing model and altering the social, political, and economic dynamics of each country. This study aims to examine the impact of institutional arrangements stemming from the 1990s neoliberal reforms in Brazil and Colombia on HRDs, focusing on geographic distribution. Employing a comparative analysis and adopting a historical institutionalism perspective, the research relies on a methodology involving multiple case studies with embedded units. Results reveal that the neoliberal reforms represented critical junctures reshaping the social and economic policies of both nations. In this context, the reforms influenced wealth distribution in both countries, subsequently impacting the unequal geographical distribution of HRD. These effects were closely tied to factors such as labor flexibility and the unregulated, unplanned expansion of dentistry courses. These elements initiated positive feedback loops, characterized by path dependence and increasing returns, which have contributed to the institutionalization and persistence of these phenomena within the state and have become entrenched in HRDs over time.

Event-triggered prescribed-time consensus for nonholonomic multi-agent systems with external disturbances

This paper considers the prescribed-time event-triggered consensus for a class of nonholonomic multi-agent systems (MASs) with external disturbances. Firstly, the nonholonomic chained MASs are divided into two subsystems, and a switching control scheme is introduced. Secondly, a distributed prescribed-time continuous protocol is proposed to ensure that all agents reach average consensus within a prescribed finite-time. Moreover, to reduce the communication costs, an event-triggered consensus protocol is further established and some related theorems are given. In addition, the Zeno behaviour can be excluded by choosing parameters appropriately. Finally, two numerical examples are presented to demonstrate the effectiveness of the proposed protocols.

Adaptive formation control of nonholonomic multirobot systems with collision avoidance and connectivity maintenance

In this paper, an adaptive cooperative formation controller is developed to force a swarm of nonholonomic mobile robots with limited sensing ranges to move along the desired reference trajectory in a predetermined formation, while maintaining communication connectivity among the initial user-specified connected robots and guaranteeing no collision between the robots. Both kinematic models and dynamic systems with parametric uncertainties are discussed. The presence of parametric uncertainties is handled by adaptive control technique. A novel artificial potential function, which is based on a 4 times differential pseudo bump function, is constructed to achieve collision avoidance and connectivity maintenance. The control design is based on a fusion of potential function, adaptive backstepping technique, and Lyapunov synthesis. The cooperative formation controller is proven to be stable and can guarantee that there is no collision between any robots and the initial connectivity of the communication network can be always maintained. The proposed formation control approach is decentralized in the sense that the control action on each robot depends only on information from its neighbours and the desired trajectory of the group. Comparative simulation and experiment studies are performed to show the effectiveness of the proposed formation controller.

Manufacturing intelligentization and technological innovation: Perspectives on intra-industry impacts and inter-industry technology spillovers

This study empirically analyzes the impacts of manufacturing intelligentization on technological innovation using panel data from 29 manufacturing industries in China for the period 2012–2019. The research findings indicate that manufacturing intelligentization has significantly positive impacts on intra-industry technological innovation. Moreover, technological innovation exhibits path dependence, in which prior innovation accumulation is advantageous for current technological innovation. Furthermore, the spatial Durbin model indicates that intelligentization has both horizontal and vertical technology spillover effects on technological innovation. Specifically, the intelligentization of horizontal- and forward-linked industries has positive impacts on technological innovation in the focal industry. Additionally, technological innovation exhibits significant spatiotemporal dependence, as manifested by the negative spillover effects of prior technological achievements in other industries on current technological innovation in the focal industry.
