Abstract

Purpose

The purpose of this study is to introduce a new concept in engineered materials and that is truss substructured materials (TSMs). These materials would be engineered to express mechanical abilities that are seldom found in nature.

Design/methodology/approach

This article starts with defining TSMs and how to classify and name TSMs. The article also introduces the theoretical modeling of TSMs, the software developed for analyzing TSMs and the parametric studies performed.

Findings

After these studies, new materials are introduced that have abilities such as negative Poisson ratio in X and Y direction, negative Poisson ratio in one direction (either x or y), self-remodeling under stress.

Research limitations/implications

The research is done in 2D, further studies in 3D using 3D printing are required to make the suggested materials a viable real-world solution.

Originality/value

The main contribution of this research work is the proposed nomenclature that creates a system for researchers to experiment and create novel and unique versions of the proposed materials. Furthermore, some of the materials developed exhibit some unique properties that may create advances in engineering with further development.

Abstract

Purpose

The purpose of this paper is to investigate the enabling factors and the customers’ acceptance of ride-hailing in Indonesia.

Design/methodology/approach

The authors adopt some constructs from the unified theory of acceptance and use of technology (UTAUT) 2 as the framework for the study to derive factors that influence the acceptance of ride-hailing in Indonesia. Samples through a convenience sampling method were collected from an online survey and were transformed into data through coding and subsequently processed using SPSS for descriptive analysis, reliability test, correlation and multiple regression analysis for hypothesis testing.

Findings

Ride-hailing started in 2015 in Indonesia. Five enabling factors make digital ride-hailing possible, the internet, smartphone, broadband wireless network, digital map and global positioning system. The authors found that performance expectancy, social influence and habit positively influence customers to accept ride-hailing in Indonesia.

Research limitations/implications

Although this research has a small sample, it is still relevant to understand people’s acceptance to the ride-hailing platform. As a ride-hailing platform is now transformed to a multisided markets platform, adoption studies or other studies on each market to cover the whole picture of the platform influence to the society, and its contribution to the national economy will be very interesting. The authors’ future research will cover various services covered by ride-hailing companies.

Originality/value

This study proposes and argues that four main enabling factors make digital ride-hailing a viable business. The study contributes to three significant factors that influence the acceptance of ride-hailing in Indonesia.

Abstract

Purpose

This paper aims to explore individuals’ economic empowerment and political empowerment association and the moderation role of entrepreneurship development programs on this relationship in the context of post-revolution Tunisia, which is a newer developing democracy.

Design/methodology/approach

The study uses a quantitative approach based on econometric modeling. A questionnaire was designed and administrated to a stratified random sample of 343 participants in the Entrepreneurship for the Participation and Inclusion of Vulnerable Youth in Tunisia program, funded by the United Nations Democracy Fund and implemented in rural northwestern Tunisia between 2017 and 2021. A coarsened exact matching method is also applied for robustness analysis.

Findings

The analysis shows that when individuals have enhanced economic decision-making agency and are involved in economic networks, they are more likely to demonstrate higher political empowerment. It also shows that expanding rural individuals’ economic opportunities by providing entrepreneurial resources, such as entrepreneurial training and microcredit, strengthens individuals’ economic empowerment and political empowerment association.

Practical implications

The study provides practical implications for policymakers in newer developing democracies. Citizens’ political empowerment and inclusion in rural areas could be promoted by developing entrepreneurship development programs, which could help reinforce the citizens-state relationship and establish more stable social contracts. The research also provides practical implications for the international development community, donor agencies and program designers through duplicating similar programs in other countries with weak central government structures (i.e. post-conflict environments, post-revolution).

Originality/value

The research attempts to contribute to the ongoing debates linking entrepreneurship, economic empowerment and political/citizen empowerment. It focuses on a Middle East and North Africa country, Tunisia, characterized by socioeconomic issues and low civic participation.

Abstract

Since 1981, the U.S. federal government has operated a price support program to help sugar beet and sugar cane producers and processors. This complex program works through a combination of loans, import quotas, and duties. As a result, sugar prices in the United States are significantly higher than world prices. For example, in December 2001, U.S. consumers paid 22.9 cents per pound, while the world price was just 9 cents per pound. The General Accounting Office estimates that the total cost to consumers is $1.9 billion a year. Uses a simple demand-and-supply framework with real-world data to assess the economic and political consequences of the U.S. sugar program.

To illustrate welfare concepts such as consumer surplus, producer surplus, and dead-weight loss in a concrete, real-world market context.

Abstract

The chapter compares the survival of old regime elites in Tunisia and Egypt after the 2011 uprisings and analyses its enabling factors. Although democracy progressed in Tunisia and collapsed in Egypt, the countries show similarities in the old elite’s ability to survive the Arab Spring. In both cases, the popular uprisings resulted in the type of elite circulation that John Higley and György Lengyel refer to as ‘quasi-replacement circulation’, which is sudden and coerced, but narrow and shallow. To account for this converging outcome, the chapter foregrounds the instability, economic decline and information uncertainty in the countries post-uprising and the navigating resources, which the old elites possessed. The roots of the quasi-replacement circulation are traced to the old elites’ privileged access to money, network, the media and, for Egypt, external support. Only parts of the structures of authority in a political regime are formal. The findings show the importance of evaluating regime change in a broader view than the formal institutional set-up. In Tunisia and Egypt, the informal structures of the anciens régimes survived – so did the old regime elites.

Abstract

In recent years, interest in educational issues in the Muslim world has grown rapidly. This interest runs parallel with a media-led exploration of all things Muslim and the ideas that are fundamental to the tenets of Islam. This trend in examining the educational issues that exist in countries that are predominantly Islamic in history, culture, and belief, is part of a wider awareness of the educational elements of a globalized system of commerce, communication, education, and modernization. The United Arab Emirates (UAE) has embraced many facets of globalization, striving to become a regional power and a new financial and commercial hub in the Middle East and a high-tech center in a globally oriented society. Along with other Arab nations, the UAE has recognized the strategic role played by education in national development and modernization.

Abstract

Purpose

This study aims to recognize the significant barriers of small and medium-sized enterprises (SMEs) in Bangladesh, hindering the adoption of total quality management (TQM). Additionally, this research intends to explore the interrelations among these barriers to develop essential managerial insights for promoting TQM implementation in SMEs.

Design/methodology/approach

The interpretive structural modeling (ISM) approach and Matrice d'impacts croisés multiplication appliquée á un classment (MICMAC) a cross-impact matrix multiplication applied to classification show the relationship among the barriers and classification of the barriers to TQM implementation respectively, and partial least squares structural equation modeling (PLS-SEM) is applied for ISM model validation.

Findings

This study examined previous literature and conducted interviews with professionals to identify 17 barriers. The study then develops and investigates a model that outlines the relationships and priorities among these barriers and categorizes them based on their impact and interdependence. This analysis can assist SMEs in implementing TQM during their operations successfully.

Practical implications

This research emphasizes the crucial obstacles that greatly affect other barriers and require immediate attention. Furthermore, this study provides valuable information for SMEs to effectively prioritize their resources and efforts to overcome these obstacles.

Originality/value

This study delves into the primary obstacles impeding the integration of TQM in SMEs through a novel approach. Additionally, this study constructs a verified contextual framework that depicts the hierarchies and interconnections among these barriers.
