Abstract
Explains why executive severance contracts contingent on a change in control (i.e. golden parachutes) have developed and reviews previous relevant research. Develops a mathematical model of their effects on shareholder wealth and uses it to determine an optimal contract which aligns the interests of shareholders and managers (i.e. where marginal benefit to shareholders equals marginal cost of the contract). Points out that these contracts alone do not guarantee that managers will aim to maximize shareholders wealth: they should form only part of a package of compensation agreements to align their interests.

Abstract
This chapter reviews developments concerning central bank digital currencies (CBDCs). It introduces, analyzes, and discusses the potential implications of CBDCs on the existing cryptoassets landscape. The chapter also provides an overview of the different approaches to adopting and implementing this new form of money. Additionally, it compares traditional cryptocurrencies, privately issued stablecoins, fiat currencies, and CBDCs. Although vastly divergent opinions exist on digital money’s purpose, benefits, and use cases, CBDCs can provide opportunities for innovation and experimentation at a central bank and systemic level. CBDCs may pave the way for democratizing access to unbundled financial services while rethinking the overall purpose of money, monetary systems, and global business.

Abstract
Brazil has been increasing its participation in the international trade market, mainly due to agricultural and forestry products, as in the case of soybeans and cellulose. This growth led to the expansion of the logistics infrastructure and its use. An important example of this trend is the port of São Luís, MA, in northern Brazil, which saw an increase in exports via rail (more than 200% growth in 6 years) and, consequently, an increase in the circulation of trains within its port complex.
This work proposes a mixed-integer linear programming model for the daily train scheduling problem at this port. All trains operated by VLI, a logistics company, are scheduled to minimize the departure times in order to improve the dwell time of freight train cars.
The railroad system in this Brazilian port consists of two classification yards, five terminals and a double-track railway for circulation. Different products such as grains, minerals, cellulose, and fuels are transported. The model also incorporates different operations at terminals and occupation restrictions due to maintenance and the physical flow of other third-party logistics companies. These features are modeled through a preprocessing step. In this phase, a series of auxiliary sets are defined to simplify constraints, circulation options are mapped, and the double-track is divided into segments based on the transit time with the objective to control track occupation.
This preprocess step also reduces the model complexity and, consequently, the computational time to solve it, as shown in the numerical tests using real-world operational data.
The main gains of the project were a reference train timetable for peak days, standardization of train crossing options, and a support tool for traffic adjustments with other rail operators.

Abstract
This chapter investigates the political and economic contexts of the controversy about the causes of the increase of income concentration in Brazil during the 1960s. That was the most important economic debate that took place under the military dictatorship that ran the country from 1964 to 1985. The perceived sharp increase in income inequality posed a challenge to the economic legitimation of the military regime, which had by the early 1970s achieved high rates of economic growth. This chapter discusses the apparent paradox of relatively open economic debate during a period of political repression, as well as its international dimension as reflected in the role played by institutions such as the World Bank.

Abstract
Purpose
The purpose of this paper is to identify what the philosophy of Martin Heidegger (1889‐1976) can contribute to the training of managers.
Design/methodology/approach
After a short introduction focussing on philosophy and management, Heidegger's potential contribution to managers will be addressed via Safranski's book Martin Heidegger: Between Good and Evil.
Findings
It is often said that change in organizations is hard or even impossible to achieve because people are afraid of change. Safranski however shows how Heidegger considers anxiety as a gateway to change. I propose to read Heidegger's Being and Time as a handbook on management skills.
Originality/value
In terms of philosophy and management an unexpected juxtaposition is made and interpreted.

Abstract
Purpose
The purpose of this paper is to evaluate a shiitake mushroom extract as a potential natural taste enhancer in low-sodium beef burgers by means of sensorial and physico-chemical assays because nowadays there is a trend in the market for the development of clean-label products.
Design/methodology/approach
Ten formulations of beef burgers were developed, varying in the percentage reduction in NaCl (0-75 per cent) and mushroom water extracts (obtained from a 5, 12.5, or 20 per cent mushroom homogenate). Sensory characterisation was performed by time-intensity (TI) and acceptance tests. In addition, physico-chemical analyses (pH, yield, shrinkage, shear force, and colour) were conducted.
Findings
Extracts obtained from 5, 12.5, or 20 per cent mushroom homogenate (E1, E2, and E3, respectively) did not enhance the salty taste in formulations with a 0 or 75 per cent reduction in NaCl. In formulations with a 50 per cent reduction in NaCl, all the extracts enhanced salinity perception, with E3 being the most effective. E3 also increased acceptance of colour, aroma, texture, flavour, and overall perception, although it caused changes in some physico-chemical characteristics (pH, yield, shrinkage, shear force, and colour).
Originality/value
The shiitake mushroom extract is a natural ingredient with a potential to serve as a taste enhancer in meat and other food products, for the purpose of reducing sodium content without compromising sensory acceptability. Therefore, this extract will enable the development of healthier products (owing to a reduction in sodium) with preserved sensory quality and will meet consumers’ requirements for the minimal use of chemical additives in food.

Abstract
Purpose
This article reflects on the development and impact of critical perspectives on international business (CPoIB) during its first decade of existence. The influence that the journal has had through its efforts to challenge orthodox understandings of international business (IB) is considered. The evolution of CPoIB is set against the changing global environment. The contributions to this 10th anniversary issue are outlined.
Design/methodology/approach
The journal's contents are reviewed and their impact assessed through an analysis of download and citation data. The position of the journal in various journal quality rankings is also examined. The contents of mainstream IB journals are compared to those of CPoIB.
Findings
During its short life, CPoIB has had an important impact on the field of IB both directly through the consideration of issues from a critical perspective in the pages of the journal and through its influence on the field of IB and critical management studies.
Research limitations/implications
The conclusions of the research are based on nine years of citation and download data as well as journal quality lists.
Practical implications
The findings of this paper provide valuable information for authors seeking a quality and impactful outlet for their research in the field of critical perspectives on IB and related disciplines. Academic and political activists in the field of IB will find theoretical backgrounds supporting their political campaigns.
Originality/value
This is the only paper to undertake an assessment of the first decade of CPoIB's development, content, and impact.
