This study investigates the relationship between the inflation targeting (IT) framework and the exchange rate pass-through (ERPT) to consumer prices in the emerging ASEAN economies (i.e., Indonesia, the Philippines, and Thailand) using a vector autoregressive (VAR) model with monthly data covering the sample period from January 1990 to July 2020. The empirical analysis is divided into two subperiods – pre-IT and post-IT periods. The impulse response analysis identified the existence of the ERPT during the pre-IT period and the loss of the ERPT during the post-IT period in all sample economies. The study speculated that the loss of the ERPT is attributable to the conformity to the Taylor principle in the IT framework in all sample economies.

The increasing accumulation of synthetic plastic waste in oceans and landfills, along with the depletion of non-renewable fossil-based resources, has sparked environmental concerns and prompted the search for environmentally friendly alternatives. Biodegradable plastics derived from lignocellulosic materials are emerging as substitutes for synthetic plastics, offering significant potential to reduce landfill stress and minimise environmental impacts. This study highlights a sustainable and cost-effective solution by utilising agricultural residues and invasive plant materials as carbon substrates for the production of biopolymers, particularly polyhydroxybutyrate (PHB), through microbiological processes. Locally sourced residual materials were preferred to reduce transportation costs and ensure accessibility. The selection of suitable residue streams was based on various criteria, including strength properties, cellulose content, low ash and lignin content, affordability, non-toxicity, biocompatibility, shelf-life, mechanical and physical properties, short maturation period, antibacterial properties and compatibility with global food security. Life cycle assessments confirm that PHB dramatically lowers CO₂ emissions compared to traditional plastics, while the growing use of lignocellulosic biomass in biopolymeric applications offers renewable and readily available resources. Governments worldwide are increasingly inclined to develop comprehensive bioeconomy policies and specialised bioplastics initiatives, driven by customer acceptability and the rising demand for environmentally friendly solutions. The implications of climate change, price volatility in fossil materials, and the imperative to reduce dependence on fossil resources further contribute to the desirability of biopolymers. The study involves fermentation, turbidity measurements, extraction and purification of PHB, and the manufacturing and testing of composite biopolymers using various physical, mechanical and chemical tests.

This contribution discusses a continuum model of large discrete networks in planar domains. For this model, the Kirchhoff law, boundary conditions and capacity constraints lead in a system optimisation approach to a infinite dimensional constrained optimisation problem and to “mixed” variational inequalities. Mixed finite element methods can be formulated for these variational inequalities such that computable discretizations of the continuum problem are obtained.

In this chapter, an air cargo shipment planning problem is considered by including individual risk factors of any sub-contracted agents. Due to competitive market conditions, air cargo forwarders are advised to remain flexible in operations. A mixed integer linear programming formulation including the potential for divisible activities is developed to model the shipment planning problem. To solve this complicated problem, we employ an ant colony optimization (ACO) methodology. Numerical examples are generated using data from both the extant literature and from a global air cargo company, allowing investigation of the viability of the novel methodology. We find that the algorithm/methodology provides effective solutions for small problem sizes.

The service sector comprises a dominant segment of the economy. Customer satisfaction, a measure of quality, is based on the degree of difference between expected quality and the actual level of quality experienced. Expected level of quality is influenced by customer perception of quality, which in turn is impacted by external and internal factors. In service industries, the interaction between the service provider and the customer may also influence quality. Thus quality may consist of tangible and intangible factors. In this chapter we consider the measurable attributes associated with quality in the service sector. Based on a specified guarantee level associated with the attribute, for example, service time, a penalty function is used to determine the impact of deviating from the guarantee level. With service time being a stochastic random variable, expected penalty costs to the service provider are found under a variety of conditions.

The service industry is a major component of the economy. Raw material, components, assemblies, and finished products are shipped between suppliers, manufacturers, distributors, and retailers. Accordingly, timely receipt of shipped goods is crucial in maintaining the efficiency and effectiveness of such service processes. A service provider offers an incentive to the customer by specifying a competitive target time for delivery of goods. Further, if the delivery time is deviant from the target value, the provider offers to reimburse the customer for an amount that is proportional to the value of the goods and the degree of deviation from the target value. The service provider may set the price to be charged as a function of product value. This price is in addition to the operational costs of logistics that are not considered in the formulated model. For protection against deviation from target due dates, the service provider agrees to reimburse the customer. The reimbursement could be based on an asymmetric loss function influenced by the degree of deviation from the target due date as well as product value. The penalties could be different for early and late deliveries since the customer may experience different impact and consequences accordingly. The chapter develops a model to determine the amount (price) that the provider should add to the cost estimate of the delivery contract for protection against delivery deviations. Such a cost estimate will include the operational costs (fixed and variable) of the shipment, to which an amount is added to cover the expected payout to customers when the delivery time deviates from the target value. The optimal price should be such that the expected revenue will at least exceed the expected payout.

The foundations of quality management have been laid throughout the history of civilization. Since the dawn of industrialization, as a consequence of an increasing division of labor, the approach has evolved dramatically in terms of analytical tools and organizational practices. This evolution is outlined in this chapter. Starting from an overview of the different possible meanings of quality, the phases characterizing modern quality management (e.g., quality control, quality assurance, etc.) are described. Geopolitical and macroeconomic considerations are factored in to account for an uneven development across countries (e.g., Japan vs US). A general trajectory is traced as the scope of quality has constantly broadened to encompass not only the product, but also interorganizational processes and the impact on the environment and the society of the company activities. Against this backdrop, the current phase is seen as a polarization between a “classic” engineering approach and a more holistic view, questioning the same boundaries of the discipline.

This paper focuses on the citizens’ movement for promoting shizensou that has arisen since the early 1990s in Japan. It ascertains the social backgrounds of the movement, which originally began as an attempt to preserve nature, and the proponents’ view of the next world and their views on nature. This analysis includes social factors such as demographic trends toward the nuclear family. Furthermore, based on written newsletter reports on shizensou, this paper will examine views of the next world, and indicate that their views are animistic. Finally, I will argue that present-day shizensou is a revitalization of the custom of scattering of the ashes, which was performed in ancient Japan, but it also involved other new elements.
