Abstract
Robust political economy (RPE) is a research program that combines insights from Austrian economics and public choice to evaluate the performance of institutions in cases of limited knowledge and limited altruism, or “worst-case scenarios.” Many critics of RPE argue that it is too narrowly focused on the bad motivations and inadequacies of social actors while smuggling in classical liberal normative commitments as part of a purported solution to these problems. This chapter takes a different tack by highlighting the ways that RPE as currently understood may not be robust against particularly bad conduct. It suggests that depending on the parameters of what constitutes a worst-case scenario, classical liberal institutions, especially a minimal state, may turn out to be less robust than some conservative or social democratic alternatives.

Abstract
Purpose
The purpose of this paper is to analyze the impact of magnetic saturation on the steady‐state operation of the induction motor (IM) drive in regard to rotor field‐oriented control (RFOC). The aim of the presented two methods is to obtain the required steady‐state torque with minimal stator current, which thus reduces stator coper losses considerably.
Design/methodology/approach
The first method is based on an analytic calculation of the peak torque‐per‐ampere ratio curve of saturated IM. The torque characteristics obtained at a constant stator current are used to calculate that value of magnetizing current which gives the minimal stator current for the required load torque. The second method directly searches the minimal stator current for the required load torque. Experiments completely confirm the efficiency of the proposed selection of a magnetizing current reference.
Findings
Operation of the IM drive strongly depends on a proper selection of the rotor flux linkage reference value, the selection of which represents an additional degree of freedom in control design. Therefore, it can be used to optimize some of those drive features subjected to voltage and current constraints. The proposed calculation procedure is simple so that can be easily implemented in practically application. However, some additional IM data like magnetizing curve, inertia moment, and coefficient of viscous friction are necessary.
Originality/value
The substantial impact of saturation on the stead‐state torque characteristics of IM, determined for the constant stator current and the constant d‐axis stator current, is determined analytically and numerically.

Abstract
The term “dynamics of interventionism” refers to a social process, i.e., a sequence of adjustments to change over time, among a great many individuals, who largely share a common set of rules of interaction.1 It is constituted by the unintended consequences at the interface between the governmental and market processes, when the scope of government is either expanding or contracting in relation to the market. Interventionism is the doctrine or system based on the limited use of political means (i.e., legitimized violent aggression (Oppenheimer, 1975[1914])) to address problems identified with laissez-faire capitalism. Thus, an intervention refers to the use of, or the threat of using, political means to influence non-violent actions and exchanges. Supporters of interventionism do not completely reject the institutions of capitalism, such as private property and the price system, but do favor using piecemeal interventions that extend beyond so-called minimal-state capitalism2 in order to combat suspected failures or abuses they associate with the unhampered market. Examples of this would include, but are not limited to, market power, externality, asymmetric information, income inequality, racial and sexual discrimination, and the business cycle.

Abstract
Purpose
The paper aims to examine accounting changes in the Ashanti Gold Corporation (AGC) in Ghana over 120 years from pre-colonialism to recent times and whether the framework of management accounting transformations in Hopper et al. (2009) is applicable.
Design/methodology/approach
Mixed data sources are used, namely, interviews, some observations of practices, historical documentation, company reports and research papers and theses. The results are categorised according to the periods and contextual factors in the Hopper et al. framework to test whether it matches the data collected.
Findings
Despotic controls with minimal management accounting but stewardship accounting to the head office in London prevailed under colonialism. Upon independence state, capitalist policies descended into politicised state capitalism. Under nationalisation, the performance of mines deteriorated, and accounting became decoupled from operations. In the early 1980s, fiscal crises forced Ghana’s government to turn to the World Bank and International Monetary Fund for loans. This period marked a gradual transformation of AGC into a foreign multinational, organised along divisional lines and currently exercises despotic control through supply chain management that renders labour precarious and is neglectful of corporate social accounting issues.
Research limitations/implications
The work challenges neo-classical economic prescriptions and analyses of accounting in developed countries by indicating its neglect of the interests of other stakeholders, especially labour and civil society. Accounting is important for development but the article infers other forms may better serve the public interest.
Originality/value
The paper tests the Hopper et al. framework with respect to a large private multinational in the commodity sector over an extended period, which differs from the case studies drawn on originally.

Abstract
The following sections will present a brief overview of theories of justice that have underpinned the development of the institutions and administration of justice in modern Western societies. It will begin with an examination of the general political–philosophical ideas and concepts in the area of justice in the modern era. It will then examine the perspectives of punishment, which are linked to these philosophical theories.

Abstract
Purpose
With a focus on the position of EU mobile workers in the Dutch meat industry, this article discusses the multi-level State efforts to enhance protection of workers who experienced limited protection of existing State and private enforcement institutions. The COVID-19 pandemic, with virus outbreaks at Dutch meat plants, fuelled public and political will to structurally improve these workers' precarious work and living conditions. Yet, the process of policy change is slow. The authors show it is the gradual transformation in the institutional environment that the State needs to counter to become more protective for EU mobile workers.
Design/methodology/approach
Using the gradual institutional change approach and the concept of State ignorance, the authors examine State responses drawing on interviews with expert stakeholders in the public and private domain, public administration records and newspaper articles.
Findings
Through knowledge creation, boosted social dialogue mechanisms, enhanced enforcement capacity and new housing legislation, the Dutch State focuses on countering gradual institutional change through which existing institutions lost their effectiveness as protectors of EU mobile workers. The organization of work is, nevertheless, not (yet) fundamentally addressed with tighter public legislation.
Originality/value
The findings contribute to a more nuanced understanding of the role of the State as multifaceted actor in institutional change processes towards increased protection for EU mobile workers.

Abstract
Most criminal justice scholars agree that the past three decades have witnessed a punitive shift in criminal justice policy, public opinion, and political rhetoric. Have these political trends also left their mark on policy approaches to due process rights? The provision of counsel to indigent defendants is a signature issue in debates over due process rights. The Supreme Court expanded dramatically the circumstances under which states were required to provide counsel in the 1960s and 1970s, though decisions about the implementation of this mandate were left to individual states. We examine the evolution of indigent defense policy, at the state and local level, over the past three decades, and ask two questions: First, did policies evolve in the directions expected by reform advocates? Second, to the extent that policies developed differently across states, how can we account for those differences? We find that refomers' optimistic projections about structure and funding have not been realized, and that adoption of progressive policies has been uneven across states. Most importantly, we find evidence that the politics of ideology and racial conflict have played a significant role in states' indigent defense policy over the past three decades.

Abstract
This article explains that in the current global context dominated by market ideology, there has been a significant shift in the nature of the state based on promarket neoliberal principles in most countries, including those in the developing world. Under this emerging neoliberal state characterized by the primacy of market forces and adoption of market-driven policies and programs, the role of the public service has also changed in terms of its increasing concern for streamlining public sector activities, enhancing economic efficiency, improving customer satisfaction, and so on. After exploring such impacts of the current neoliberal state formation on the public service's role, the article briefly examines the socio-political consequences of this changing role, especially in developing nations.

Abstract
Purpose
The purpose of this paper is to propose mover position control of linear induction motor (LIM) using an adaptive backstepping approach based on field orientation.
Design/methodology/approach
First, the indirect field‐oriented control LIM is derived. Then, an adaptive backstepping approach based on field‐oriented control of LIM is proposed to compensate the uncertainties which occur in the control. Mover position amplitude tracking objective is formulated, under the assumption of unknown total mass of the moving element, viscous friction, and load force, so that the position regulation is achieved.
Findings
The effectiveness and robustness of the proposed control scheme are verified by numerical simulation using Matlab/Simulink model. The numerical validation results of the proposed scheme have presented good transient control performances and robustness to uncertainties compared to the conventional backstepping control design.
Originality/value
The paper presents an adaptive backstepping approach for LIM control that achieves mover position amplitude tracking objective under mechanical parameter variation.

Abstract
The purpose of the research is to determine the essence and notion of economic violation of law and their varieties, and to determine the reasons that lie in the basis of this negative social phenomenon. The authors use the philosophical law of integrity and struggle of contradictions and rather-legal, historical and legal, and formal and legal methods of scientific cognition. Such laws of dialectics and transition of quantitative changes into qualitative changes, negation of negation, and others are used. Signs and types of economic violations of law are analyzed and their predetermination by the conflict character of economic relations is noted. Comparison of economic violations of law that are peculiar for administrative and market models of economy is performed. The universal character of economic relations as objects of legal protection is shown. Classification of economic violations of law, based on the level of their public danger and spheres of distribution, is provided. Special attention is paid to civil and legal violations of law as a variety of economic violations of law, based on not anti-social settings of the subject but conflict with the borrowed system of values, which is alien to most members of society. The notion “economic violation of law” is of the collective character and includes illegal actions regarding economic relations, and the latter are of the conflict character due to different interests of subjects, the existing competition, and striving for obtaining profit. Economic violation of law is an illegal form of solving the existing conflict, which leads to application of measures of legal responsibility. The causes of economic violations of law could be overcome by implementation of the values and ideals of justice in the legal norms. They should be based on historical, cultural, spiritual, and legal traditions. All that is imposed artificially is destined for rejection and creation of new conflicts, including economic violations of law.
