Abstract

Purpose

This study examines employee emotional exhaustion and turnover intention as the consequences of problematic customer behaviors and tests the role of perceived organizational justice and job satisfaction in mitigating these consequences.

Design/methodology/approach

A four-hypothesis model was tested using partial least squares structural equation modeling (PLS-SEM) based on a two-phase survey of 369 frontline services employees in Vietnam with a three-month time lag.

Findings

The study shows that abusive and unreasonably demanding customer behaviors have positive effects on emotional exhaustion, which, in turn, reduces job satisfaction and, subsequently, turnover intention. It also reveals that organizational justice mechanisms attenuate the positive association between emotional exhaustion and turnover intention. Job satisfaction indirectly mitigated the turnover intention of emotionally exhausted employees who had to deal with problematic customer behaviors, especially in the service sector in Vietnam, an emerging market.

Originality/value

Building upon the social exchange theory (SET) and the conservation of resources theory (COR), this study extended the research on organizational justice with respect to emotional exhaustion in the customer service sector that received less attention previously. Rather than merely focusing on the interpersonal factors (e.g. respect and sensitivity) as organizational support does, organizational justice encompasses employees' perception of fairness of outcome and the whole process in an organization to reach decisions.

Abstract

Purpose

The purpose of this paper is to ascertain if age, gender, management experience and government work experience actually make a difference in the ethical development of respondents in Vietnam, an emerging economy in Southeast Asia.

Design/methodology/approach

A quantitative self-administered survey was conducted with a convenience sample of Vietnamese working adults obtained through educational institutions, businesses and entrepreneurs and private and public sector organizations. This study used Clark and Clark’s (1966) Personal Business Ethics Scores measure. The Vietnamese version questionnaire was distributed, and a total of 704 surveys were fully completed and analyzed.

Findings

Statistically significant differences were found in the variables of age, gender and government work experience. Management experience did not lead to any significant differences. Consequently, Kohlberg’s moral development theory regarding ethical development is partially supported.

Research limitations/implications

This study used a convenience sample population. Future studies can compare specific populations in different parts of the country with similar working backgrounds and demographic variables. The small sample size is not necessarily representative of an entire country or the culture in Vietnam. Furthermore, it would be meaningful to investigate the relationship between ethical development and the demographic variables among other Asian countries near Vietnam. Finally, longitudinal studies can be implemented by future researchers to investigate the effects of changes in demographic variables on moral development.

Practical implications

Females should be studied more to determine the factors that they consider when making decisions that impact others. Having longer time “socializing” with organizational values might be a stronger influence on ethical behaviors of a person. Vietnamese people are less tolerant for unethical behaviors when they are much younger and when they are much older.

Social implications

The importance of ethics education programs at the national and organizational levels is underscored as a key element to combat corruption. Several specific recommendations on how to enhance the fight against corruption and bribery were provided.

Originality/value

This study contributes to the moral development theory research and sheds light on the impact of age, gender, government work experience and management experience gained through the development process on ethical decision-making of Vietnamese people. Academicians, managers, practitioners, government leaders and the like can benefit from the findings of this paper.

Abstract

The evolution and trends of special education and educational leadership are evident, especially in recent years. The former has strived to provide equitable educational opportunities to students with disabilities. The latter has dealt with how people in positions of authority in K-12 schools create policy, use resources, and influence other people to achieve educational goals. Together, these notions constitute an idea that school leaders and administrators can provide insight, oversight, assistance, and guidance toward creating educational environments for students with and without disabilities. This chapter examines the current state of special education and educational leadership by exploring the evolution of special education, relevant legal cases, and the enactment of inclusive education. Furthermore, this chapter addresses contemporary issues for leaders, such as the influence of the COVID-19 pandemic, while dealing with special education and the increasing pressure from families for equity for students with disabilities.

Abstract

Purpose

The consolidation behavior of prefabricated vertical drain (PVD)-installed soft deposits mainly depends on the PVD performance. The purpose of this study is to propose a numerical solution for the consolidation of PVD-installed soft soil using the large-strain theory, in which the reduction of discharge capacity of PVD according to depth and time is simultaneously considered.

Design/methodology/approach

The proposed solution also takes into account the general constitute relationship of soft soil. Subsequently, the proposed solution is applied to analyze and compare with the monitoring data of two cases, one is the experimental test and another is the test embankment in Saga airport.

Findings

The results show that the reduction of PVD discharge capacity according to depth and time increased the duration required to achieve a certain degree of consolidation. The consolidation rate is more sensitive to the reduction of PVD discharge capacity according to time than that according to the depth. The effects of the reduction of PVD discharge capacity according to depth are more evident when PVD discharge capacity decreases. The predicted results using the proposed numerical solution were validated well with the monitoring data for both cases in verification.

Research limitations/implications

In this study, the variation of PVD discharge capacity is only considered in one-dimensional consolidation. However, it is challenging to implement a general expression for discharge capacity variation according to time in the two-dimensional numerical solution (two-dimensional plane strain model). This is the motivation for further study.

Practical implications

A geotechnical engineer could use the proposed numerical solution to predict the consolidation behavior of the drainage-improved soft deposit considering the PVD discharge capacity variation.

Originality/value

The large-strain consolidation of PVD-installed soft deposits could be predicted well by using the proposed numerical solution considering the PVD discharge capacity variations according to depth and time.

Abstract

Unsustainable logging and illegal logging for domestic and international trade and trafficking continue to lead to deforestation. It is crucial that Sustainable Development Goal 15 ‘Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss’ is achieved to maintain the livelihoods of people and protect the planet. This is the case in Vietnam as well, where many people, including indigenous groups, rely on the forest for their survival. Drawing on semistructured interviews in Vietnam and a literature review, we investigate how the abuse of forest policies leads to human insecurity. From this, we propose solutions to (1) end unsustainable harvesting and illegal logging (SDG 15.7), (2) integrate the value of forests (culturally and economically) into national and local planning, the development process and poverty elimination strategies (SDG 15.9) and (3) improve the use of forest protection funding provided by international donors.

Abstract

The issue of export instability exerts an enduring fascination for economists with an interest in the area of economic development. Over several decades a voluminous literature has emerged embracing debates on the domestic consequences and on the causes of export instability. The purpose here is to examine these debates and an attempt is made to set out different theoretical stances, to classify and examine empirical findings, and to indicate the directions in which the debates have moved. Such a statement of a review article's purpose is, of course, incomplete without more specific delineation of the boundaries within which the general objectives are pursued. Here that delineation has three facets.

Abstract

Purpose

This paper aims to present a new discrete method to predict average excess pore pressure and degree of consolidation for soft ground using prefabricated vertical drains under time-dependent surcharge and/or vacuum loading and multi-soil layers.

Design/methodology/approach

The drain is discretized into a number of mesh points at which the average excess pore pressure is estimated. The conventional Laplace technique is used to solve the analytical equations. The proposed method is validated with previous findings reported in the literature. Moreover, field measurements are used to verify the accuracy of the proposed method with a case history of ground improvement by prefabricated vertical drains using the vacuum consolidation technique.

Findings

In comparison to past studies, this new discrete method is simpler to be implemented in a spreadsheet calculation to achieve a rational solution with less computational time for similar consolidation problems. Moreover, the current approach also incorporates a solution for multi-soil layers, which can hardly be derived by analytical solutions.

Originality/value

According to authors’ knowledge, this is the first-time discrete method by Laplace transform technique is applied for the vertical drain.

Abstract

Due to the increasing size and complexity of construction projects, construction engineering and management involves the coordination of many complex and dynamic processes and relies on the analysis of uncertain, imprecise and incomplete information, including subjective and linguistically expressed information. Various modelling and computing techniques have been used by construction researchers and applied to practical construction problems in order to overcome these challenges, including fuzzy hybrid techniques. Fuzzy hybrid techniques combine the human-like reasoning capabilities of fuzzy logic with the capabilities of other techniques, such as optimization, machine learning, multi-criteria decision-making (MCDM) and simulation, to capitalise on their strengths and overcome their limitations. Based on a review of construction literature, this chapter identifies the most common types of fuzzy hybrid techniques applied to construction problems and reviews selected papers in each category of fuzzy hybrid technique to illustrate their capabilities for addressing construction challenges. Finally, this chapter discusses areas for future development of fuzzy hybrid techniques that will increase their capabilities for solving construction-related problems. The contributions of this chapter are threefold: (1) the limitations of some standard techniques for solving construction problems are discussed, as are the ways that fuzzy methods have been hybridized with these techniques in order to address their limitations; (2) a review of existing applications of fuzzy hybrid techniques in construction is provided in order to illustrate the capabilities of these techniques for solving a variety of construction problems and (3) potential improvements in each category of fuzzy hybrid technique in construction are provided, as areas for future research.

Abstract

Managing complex construction projects is a challenging task because it involves multiple factors and decision-making processes. A systematic evaluation of these complex factors is imperative for achieving project success. As most of these factors are qualitative or intangible in nature, decision makers often rely on subjective judgements when comparing and evaluating them. The hybrid techniques that integrate fuzzy set theory and the analytic hierarchy process (AHP) are able to deal with such problems. This chapter discusses various hybrid techniques of the fuzzy AHP and presents an application of these techniques to the evaluation of transportation project complexity, which is essential for prioritising resource allocation and assessing project performance. Project complexity can be quantified and visualised effectively with the application of the fuzzy AHP. This chapter enhances the understanding of construction project complexity and fuzzy hybrid computing in construction engineering and management. Future research should address the calibration of fuzzy membership functions in pairwise comparisons for each individual decision maker and develop computational tools for solving optimisation problems in the constrained fuzzy AHP. In the area of construction project complexity, future research should investigate how scarce resources are allocated to better manage complex projects and how appropriate resource allocation improves their performance.
