Abstract

Purpose

The purpose of this paper is to explain in detail the optimization of the sensitivity versus the power consumption of a pressure microsensor using multi-objective genetic algorithms.

Design/methodology/approach

The tradeoff between sensitivity and power consumption is analyzed and the Pareto frontier is identified by using NSGA-II, AMGA-II and ɛ-MOEA methods.

Findings

Comparison results demonstrate that NSGA-II provides optimal solutions over the entire design space for spread metric analysis, and AMGA-II is better for convergence metric analysis.

Originality/value

This paper provides a new multiobjective optimization tool for the designers of low power pressure microsensors.

Abstract

Purpose

In a global positioning system (GPS) receiver, one of the most time-consuming tasks is to identify and track the visible satellites. The paper aims to propose and examine in detail new and shorter identification patterns or lite pseudo-codes – pseudo-random numbers (PRNs) – that allow GPS receivers to reduce dramatically the computational effort to identify and track GPS satellites. Obtaining lite pseudo-codes is a multi-objective optimization problem that the paper resolves using genetic algorithms (GAs).

Design/methodology/approach

The lite PRNs are obtained by using NSGA-II and omni-optimizer multi-objective optimization techniques.

Findings

The new PRNs obtained with the proposed single/multi-objective solutions are always better than previously presented when the highest detection peak (DP) is required for the GPS receiver.

Originality/value

Results demonstrate that the problem of “obtaining lite pseudo-codes” is a multi-objective optimization problem. In other words, the solutions obtained with the single-objective approach could belong to a local minimum. The multi-objective approach provides a better solution than the single-objective approach in a 37 percent of the satellites while in other cases the multi-objective approach reaches the same DPs with a similar noise.

Abstract

This study assessed the contribution of containerization to the development of Western Ports, Lagos Nigeria. The aim was to assess the influence of containerization on some indices of port development such as port infrastructure development, ship turnaround time, cargo dwell time and congestion. Questionnaire was used to gather information on the contribution of containerization to change in maritime trade in the country, the influence of containerization on terminal expansion, congestion, level of investment in container port infrastructure as well as the influence of such investment on container dwell time and ship turnaround time (TAT) and the competitiveness of container terminal within Nigeria port systems and with other developed container ports of the world. Secondary data used included statistics of reports of operations of Western Ports between 2000 and 2010 as reported by NPA, as well as reports of some selected ports derived from Containerization International Year Book, which were used in this study for the sake of global reference. Summary tables and ANOVA for the analysis of the data. Results revealed a significant contribution of containerization to maritime trade relative to the ports’ annual records but with no significant influence on ship turnaround time, cargo dwell time congestion which are determinants of port productivity and competitiveness. The study concluded that Western Ports have still not reaped gains of containerization and lacking in competitiveness when compared with other developed ports of the world.

Abstract

Purpose

This study aims to analyze the establishment of sustainable microfranchises by women victims of the conflict (WVC) entrepreneurs who suffered the consequences and impacts of the longest-running internal conflict in the Americas. Additionally, this research seeks to underscore the transformative role of women entrepreneurs-for-peace (WE4P) in a post-peace agreement society.

Design/methodology/approach

This study seeks to contribute to theory building on sustainable business models (SBMs) at the base of the pyramid (BoP) theory from a single case study of the Colombian microfranchise TechOil. The theoretical sampling process guided the selection of data sources, which include semi-structured interviews, company and microfranchise donors’ reports, websites and external expert interviews to support the findings. The research adopts a framework of intro-entrepreneurship characteristics, ambiance, organization and sustainability.

Findings

TechOil offers a valuable case study for understanding how the phenomenon of microfranchise as an SBM spills over the BoP and promotes gender equality. The authors also developed a new SBM typology by extending the theory inductively.

Practical implications

The paper highlights WE4P and introduces microfranchises as a new SBM typology, offering insights into policy, practice and societal transformation in post-peace agreement zones.

Originality/value

The issue of WVC entrepreneurs in post-peace agreement settings remains under-reviewed and under-theorized. This study’s originality lies in introducing microfranchises as a new SBM typology, emphasizing the importance of gender equality and women’s roles in sustainable development and addressing the overlooked link between entrepreneurship and peace, contributing to global applicability.

Objetivo

Abstract

The goal of this chapter is to reexamine the nature and structure of the military–industrial complex (MIC) through the works of John Kenneth Galbraith. MIC, or military power as he prefers, is a coalition of vested interests within the state and industry that promoted the military power in the name of “national security” for their interests. Galbraith’s theory of giant corporations helps us understand the role of military corporations in the MIC. Moreover, he is a critical scholar in examining this topic because he was a political insider in the Roosevelt, Kennedy, and Johnson administrations and a prominent public intellectual against the Vietnam War. Against this background, this chapter has three parts. After explaining the development of military Keynesianism with respect to the main economic thoughts, it examines the history of the MIC and its impact on economic priorities during and after the Cold War through Galbraith’s works. Finally, this chapter discusses MIC’s relevancy today and evaluates Galbraith’s prophecies.

Abstract

Purpose

While entrepreneurship has long been heralded for its positive contributions, there is a growing recognition of its “dark side,” characterized by unproductive, unethical and destructive actions. This exploratory literature review aims to illuminate the underexplored dark side of entrepreneurship, thereby enriching the discourse on entrepreneurship’s dual nature.

Design/methodology/approach

This study employs a robust mixed-method approach, integrating phenomenologically detailed co-citation bibliographic coupling with detailed thematic data and code-weaving. Science mapping tools like R-Bibliometrix and VOSviewer enhance the credibility of the findings by providing a sophisticated and reproducible methodological framework.

Findings

This review defines dark entrepreneurship, its characteristics, and its complexities. We introduced the “Dark Entrepreneurship Trinity”: Ethical Complexity, Institutional Navigation and Conflict Entrepreneurialship, with Institutional Navigation as the apex theme. It elucidates how this theme influences ethical dilemmas and operational strategies in conflict zones, illustrated through a diagram depicting their complex interrelations and dynamics.

Originality/value

The originality of this literature review lies in its comprehensive synthesis of the dark side of entrepreneurship. This review significantly contributes to the academic discourse by delineating a clearer picture of the destructive potentials of entrepreneurship. It compiles existing research, critically addresses the gaps and suggests future pathways for empirical studies.

Abstract

Purpose

European countries face the crucial challenge of integrating newly arrived refugees into society. The purpose of this paper is to explore the feasibility of using e-government services developed by local authorities, as well as NGOs, to support integration processes by analyzing migrants’ perceptions of the utility, usability and efficacy of social computing applications and their impact on integration.

Design/methodology/approach

A random sample of 67 newly arrived refugees in Kronoberg County, Sweden, responded to a questionnaire in English, Swedish and Arabic comprising 26 questions covering six central domains (employment, housing, education, health, citizenship and m-government/information and communication technology for refugees).

Findings

The successful design and implementation of digital solutions to address social issues or organizational needs are best achieved through collaboration among public, private and academic institutions. The potential use of social computing applications and online services as a resource to support refugee integration processes is determined by people’s preferences and skills when using digital devices. Moreover, newcomers have negative perceptions of online services and sharing personal information because of a lack of confidence and mistrust of social computing applications.

Research limitations/implications

Findings cannot necessarily be extrapolated to Sweden as a whole, or to other European countries, owing to the Swedish government’s determination to devolve decision-making over certain refugee-related issues to the county and municipal levels, and to various European digital ecosystems.

Originality/value

This paper contributes to the analysis of the utility and efficacy of e-government services to integrate newly arrived refugees. This paper points to future improvements in social computing applications and shows the potential of public and third-sector institutions to facilitate the integration of new refugee communities and improve their quality of life.

Abstract

Purpose

This paper explores the effect of port's service time, particularly the mean and variability, on shippers' total landed costs to determine the competitive position of the port and derive recommendations for the strategic design of port services.

Design/methodology/approach

The competitive position of a port is estimated considering the service level offered to the end-users of the port such as port service time, its variability and its effect on the total landed costs observed by the port users. The proposed methodology is meant to help ports to determine the required service time levels to maintain or gain a competitive advantage against other ports, in terms of attracting common hinterland's customers.

Findings

Results show the advantages of considering service levels factors to determine the competitive position of a port, and what are the minimum characteristics required to capture more traffic volumes, that can help port managers to take strategic design decisions to better position the port in the current fierce market.

Research limitations/implications

The proposed methodology is illustrated by considering a case study, which is the Port of Guaymas in Mexico. Data was not directly collected by the port, but based on interviews with shippers and public information, a representative case is presented. Due to a confidentiality agreement with the Port, specific references for most of the data used to estimate the model's parameters are not provided. The analysis is intended to show the potential value of this mechanism and can be used for evaluating the competitive position, from a high-level perspective, of any port to determine potential hinterland by improving the service level of the port.

Originality/value

The existing literature on port choice and port competition has not previously considered the effect of port service levels under the perspective of total landed costs of the users, being this paper a contribution to fulfill this gap.

Abstract

There has been an explosion of interest in “Equity, Diversity, and Inclusion” (EDI) – also referred to as DEI among other acronyms. On the one hand, this management trend has the potential to draw attention to the ways in which organizational practices and climates can be transformed to have a positive impact on the underrepresentation of women and other marginalized and excluded groups in the workplace. On the other hand, there may be real consequences for women as EDI replaces other concepts such as women's rights, gender equality, affirmative action, employment equity, gender discrimination, etc. This chapter applies a gender lens to the EDI concept and management policy and practice. It juxtaposes EDI's emergence with the lack of progress on gender equality that is observed and measured in many regions of the world and highlights several critiques that may explain this lack of progress. It also identifies what EDI policies and practices need to take into consideration to better address gender inequality in the workplace. Legal approaches are discussed along with a list of potential areas of research on EDI and gender equality to determine the best path forward for making concrete progress on true equality for women in the workplace.
