Abstract

Purpose

The purpose of this paper is to fill a gap between experimental and abstract‐theoretic models of reaction‐diffusion computing. Chemical reaction‐diffusion computers are amongst leading experimental prototypes in the field of unconventional and nature‐inspired computing. In the reaction‐diffusion computers, the data are represented by concentration profiles of reagents, information is transferred by propagating diffusive and phase waves, computation is implemented in interaction of the traveling patterns, and results of the computation are recorded as a final concentration profile.

Design/methodology/approach

The paper analyzes a possibility of co‐algebraic representation of the computation in reaction‐diffusion systems using reaction‐diffusion cellular‐automata models.

Findings

Using notions of space‐time trajectories of local domains of a reaction‐diffusion medium the logic of trajectories is built, where well‐formed formulas and their truth‐values are defined by co‐induction. These formulas are non‐well‐founded set‐theoretic objects. It is demonstrated that the logic of trajectories is a co‐algebra.

Research limitations/implications

The paper uses the logic defined to establish a semantical model of the computation in reaction‐diffusion media.

Originality/value

The work presents the first ever attempt toward mathematical formalization of reaction‐diffusion processes and is built building up semantics of reaction‐diffusion computing. It is envisaged that the formalism produced will be used in developing programming techniques of reaction‐diffusion chemical media.

Abstract

Purpose

As stated in the United Nations Global Assessment Report 2022 Concept Note, decision-makers everywhere need data and statistics that are accurate, timely, sufficiently disaggregated, relevant, accessible and easy to use. The purpose of this paper is to demonstrate scalable and replicable methods to advance and integrate the use of earth observation (EO), specifically ongoing efforts within the Group on Earth Observations (GEO) Work Programme and the Committee on Earth Observation Satellites (CEOS) Work Plan, to support risk-informed decision-making, based on documented national and subnational needs and requirements.

Design/methodology/approach

Promotion of open data sharing and geospatial technology solutions at national and subnational scales encourages the accelerated implementation of successful EO applications. These solutions may also be linked to specific Sendai Framework for Disaster Risk Reduction (DRR) 2015–2030 Global Targets that provide trusted answers to risk-oriented decision frameworks, as well as critical synergies between the Sendai Framework and the 2030 Agenda for Sustainable Development. This paper provides examples of these efforts in the form of platforms and knowledge hubs that leverage latest developments in analysis ready data and support evidence-based DRR measures.

Findings

The climate crisis is forcing countries to face unprecedented frequency and severity of disasters. At the same time, there are growing demands to respond to policy at the national and international level. EOs offer insights and intelligence for evidence-based policy development and decision-making to support key aspects of the Sendai Framework. The GEO DRR Working Group and CEOS Working Group Disasters are ideally placed to help national government agencies, particularly national Sendai focal points to learn more about EOs and understand their role in supporting DRR.

Originality/value

The unique perspective of EOs provide unrealized value to decision-makers addressing DRR. This paper highlights tangible methods and practices that leverage free and open source EO insights that can benefit all DRR practitioners.

Abstract

The Bureau of Economics in the Federal Trade Commission has a three-part role in the Agency and the strength of its functions changed over time depending on the preferences and ideology of the FTC’s leaders, developments in the field of economics, and the tenor of the times. The over-riding current role is to provide well considered, unbiased economic advice regarding antitrust and consumer protection law enforcement cases to the legal staff and the Commission. The second role, which long ago was primary, is to provide reports on investigations of various industries to the public and public officials. This role was more recently called research or “policy R&D”. A third role is to advocate for competition and markets both domestically and internationally. As a practical matter, the provision of economic advice to the FTC and to the legal staff has required that the economists wear “two hats,” helping the legal staff investigate cases and provide evidence to support law enforcement cases while also providing advice to the legal bureaus and to the Commission on which cases to pursue (thus providing “a second set of eyes” to evaluate cases). There is sometimes a tension in those functions because building a case is not the same as evaluating a case. Economists and the Bureau of Economics have provided such services to the FTC for over 100 years proving that a sub-organization can survive while playing roles that sometimes conflict. Such a life is not, however, always easy or fun.

Abstract

Allocating budget optimally to marketing channels is an increasingly difficult venture. This difficulty is compounded by an increase in the number of marketing channels, a rise in siloed data between marketing technologies, and a decrease in individually identifiable data due to legislated privacy policies. The authors explore the rich attribution modeling literature and discuss the different model types and approaches previously used by practitioners and researchers. They also investigate the changing landscape of marketing attribution, discuss the advantages and disadvantages of different data handling approaches (i.e., aggregate vs. individualistic data), and present a research agenda for future attribution research.

Abstract

This study investigates the impact of state antitakeover legislation on the market value of affected firms and considers the role that both acquisition attractiveness, as measured by firm size, and antitakeover amendments play in the market reaction. When separating the sample by size and by the presence of amendments, small firms display a negative reaction to the legislation, large firms show no reaction, firms without amendments react negatively, and there is a positive reaction for firms with amendments. When separating the sample on the basis of both dimensions, small firms without amendments, the most attractive acquisition targets, experience a significant, negative market response. Large firms with amendments, the least attractive group, are positively affected. The two intermediate groups are not significantly affected.

Abstract

In resolution A/RES/74/4, the U.N. Nations General Assembly adopted the Decade of Action to accelerate the achievement of the SDGs by 2030. The Decade of Action calls to improve actual efforts to accomplish the 2030 agenda for governments, civil society, the private sector, and other stakeholders. This call is the last opportunity we have to reach SDG9. Still, unfortunately, the COVID-19 pandemic has severely affected all industrial sectors, which is unlikely to achieve inclusive and sustainable industrialisation by 2030. This chapter illustrates the adverse effects that the construction, manufacturing, and hospitality industries have suffered since the beginning of the COVID-19 pandemic and how they gradually have returned to the new normal. It also shows the case of the industry that could be considered the ‘champion in the covid era’, the high-tech industry. Predominantly in covid times, high-tech firms have been a synonym for technological innovation, which is an absolute necessity to encourage competitiveness in all industrial sectors, mainly in essential activities. Finally, the chapter is closed with an invitation to reflect on the fundamental principle of SDG9, which is sustainable industrialisation, but above all, inclusivity. SDG9 cannot be considered achieved until its benefits are transferred to the countries in the global south.

Abstract

Purpose

The purpose of this paper is to explore innovations in customer experience at the intersection of the digital, physical and social realms. It explicitly considers experiences involving new technology-enabled services, such as digital twins and automated social presence (i.e. virtual assistants and service robots).

Design/methodology/approach

Future customer experiences are conceptualized within a three-dimensional space – low to high digital density, low to high physical complexity and low to high social presence – yielding eight octants.

Findings

The conceptual framework identifies eight “dualities,” or specific challenges connected with integrating digital, physical and social realms that challenge organizations to create superior customer experiences in both business-to-business and business-to-consumer markets. The eight dualities are opposing strategic options that organizations must reconcile when co-creating customer experiences under different conditions.

Research limitations/implications

A review of theory demonstrates that little research has been conducted at the intersection of the digital, physical and social realms. Most studies focus on one realm, with occasional reference to another. This paper suggests an agenda for future research and gives examples of fruitful ways to study connections among the three realms rather than in a single realm.

Practical implications

This paper provides guidance for managers in designing and managing customer experiences that the authors believe will need to be addressed by the year 2050.

Social implications

This paper discusses important societal issues, such as individual and societal needs for privacy, security and transparency. It sets out potential avenues for service innovation in these areas.

Originality/value

The conceptual framework integrates knowledge about customer experiences in digital, physical and social realms in a new way, with insights for future service research, managers and public policy makers.

Abstract

This paper critically examines the influence of information technology (IT) on women’s career structures. Globalization is forcing an increasing inter‐dependence of radically re‐engineered labour forces and the further “internal” exploitation of the internationalization of the dual labour market many women have endured. The global trend is towards further fragmenting a shrinking, gender‐based set of career opportunities and creating an increasingly marginalized, part‐time, “pink collar” labour force, associated with the putative revolution of the tertiary sector transforming out of industrial, manufacturing economies. The implications of the emergence of a “pink collar” labour force largely go unexamined. The much heralded argument that IT will transform “coercive” organizational structures and work practices needs, yet again, to be critically examined in the context of the further destruction of professional opportunities for women in radically re‐engineered public sectors, aggressively “micro‐economized” labour forces and rapidly dissipating organizational and social contracts.

Abstract

Sport has evolved into one of the largest industries in Australia and there is a corresponding increased interest in the factors influencing fan loyalty. This paper presents a theoretically developed conceptual model which empirically tests the relationships between fan identification, sports involvement, following sport and fan loyalty. Survey results indicate that fan identification, following sport and involvement positively influence fan loyalty, while following sport was found to mediate the involvement-fan identification relationship.
