Abstract

Purpose

Inland shipping has been extensively recognised as a sustainable, efficient and good alternative to rail and road modes of transportation. In recent years, various authorities and academic researchers have advocated shifting from road to other sustainable modes like inland waterway transport (IWT) or rail transport. Academic work on modernisation and technological innovations to enhance the effectiveness and efficiency of waterborne transportation is becoming apparent as a growing body of literature caused by the need to achieve a sustainable transport system. Thus, it became apparent to explore the research trends on IWT.

Design/methodology/approach

A systematic and structured literature review study was employed in this paper to identify the challenges and concepts in modernising inland waterways for freight transportation. The review analysed 94 articles published in 54 journals from six well-known databases between 2010 and 2022.

Findings

The key findings of this review are that despite various challenges confronting the sector, there have been successful cases of technological advancement in the industry. The main interest among scholars is improving technical and economic performance, digitalisation, and safety and environmental issues. The review revealed that most of the literature is fragmented despite growing interest from practitioners and academic scholars. Academic research to address the strategic objectives, including strengthening competitiveness (shipbuilding, hydrodynamics, incorporating artificial intelligence into the decision-making process, adopting blockchain technology to ensure transparency and security in the transactions, new technologies for fleets adaptation to climate change, more effective handling, maintenance and rehabilitation technologies), matching growth and changing trade patterns (intermodal solutions and new logistics approaches) are major causes of concerns.

Originality/value

By employing the approach of reviewing previously available literature on IWT review papers, this review complements the existing body of literature in the field of IWT by providing in a single paper a consolidation of recent state-of-the-art research on technological developments and challenges for inland waterways freight transport in the intermodal supply chain that can act as a single resource to keep researchers up to date with the most recent advancements in research in the domain of inland waterway freight transport. Additionally, this review identified gaps in the literature that may inspire new research themes in the field of IWT.

Abstract

Purpose

Unforeseen events can disrupt the operational process and negatively impact emergency resources optimization and its supply chain. A limited number of studies have addressed risk management issues in the context of emergency supply chains, and this existing research lacks inbuilt and practical techniques that can significantly affect the reliability of risk management outcomes. Therefore, this paper aims to identify and practically analyze the specific risk factors that can most likely disrupt the normal functioning of the emergency supply chain in disaster relief operations.

Design/methodology/approach

This paper has used a three-step process to investigate and evaluate risk factors associated with the emergency supply chain. First, the study conducts a comprehensive literature review to identify the risk factors. Second, the research develops a questionnaire survey to validate and classify the identified risk factors. At the end of this step, the study develops a hierarchical structure. Finally, the research investigates the weighted priority of the validated risk factors using the fuzzy-analytical hierarchy process (FAHP) methodology. Experts were required to provide subjective judgments.

Findings

This paper identified and validated 28 specific risk factors prevalent in emergency supply chains. Based on their contextual meanings, the research classified these risk factors into two main categories: internal and external risk factors; four subcategories: demand, supply, infrastructural and environmental risk factors; and 11 risk types: forecast, inventory, procurement, supplier, quality, transportation, warehousing, systems, disruption, social and political risk factors. The most significant risk factors include war and terrorism, the absence of legislative rules that can influence and support disaster relief operations, the impact of cascading disasters, limited quality of relief supplies and sanctions and constraints that can hinder stakeholder collaboration. Therefore, emergency supply chain managers should adopt appropriate strategies to mitigate these risk factors.

Research limitations/implications

This study will contribute to the general knowledge of risk management in emergency supply chains. The identified risk factors and structural hierarchy taxonomic diagram will provide a comprehensive risk database for emergency supply chains.

Practical implications

The research findings will provide comprehensive and systemic support for respective practitioners and policymakers to obtain a firm understanding of the different risk categories and specific risk factors that can impede the effective functioning of the emergency supply chain during immediate disaster relief operations. Therefore, this will inform the need for the improvement of practices in critical aspects of the emergency supply chain through the selection of logistics and supply chain strategies that can ensure the robustness and resilience of the system.

Originality/value

This research uses empirical data to identify, categorize and validate risk factors in emergency supply chains. This study contributes to the theory of supply chain risk management. The study also adopts the fuzzy-AHP technique to evaluate and prioritize these risk factors to inform practitioners and policymakers of the most significant risk factors. Furthermore, this study serves as the first phase of managing risk in emergency supply chains since it motivates future studies to empirically identify, evaluate and select effective strategies that can eliminate or minimize the effects of these risk factors.

Abstract

Purpose

The globalization of the market economy and the technology revolution present multiple demands for education to meet the needs of the knowledge society. In this global context, work-based learning (WBL) has become increasingly valuable and critical for individuals and governments to enhance employability and to produce competitive workforces. Yet, the interdependence nature of globalization urges us to learn from each other the various theoretical and methodological approaches to WBL. Applying an appreciative inquiry, the purpose of this paper is to propose the transformation of current WBL practices by integrating or “meshing” Confucian Learning Model (CLM) into Western approaches for sustainable human development in this multi-cultural economic-driven global context.

Design/methodology/approach

This study is grounded in literature review and critical examination of profound pedagogical theories and practices from both Western and Eastern perspectives. Western education philosophies, learning theories, and models are critically examined and contrasted with CLM an important Eastern perspective in order to identify the major limitations of current WBL development. Appreciative inquiry and comparative view are applied as methods to highlight the significance of integrating or meshing CLM into the Western approaches to transform current WBL practices in this global context.

Findings

WBL has greatly benefited current workforce development worldwide, which is well documented in the literature. However, through futuristic and holistic human development perspectives, current WBL development is seen as moving toward pragmatism and utilitarianism due to overemphasizing the use of education for economic competition and for satisfying employers’ immediate work/job needs. Through an “appreciative eye” and comparative lens, this paper helps identify an urgent need to integrate or mesh CLM, an important Eastern perspective, into Western perspectives for enhanced theoretical foundations and more holistic and systemic practical approaches to transform current WBL practices for global sustainable human development.

Originality/value

This paper employs a unique method of “appreciative eye” and comparative lens through which scholars and practitioners may identify what is missing but needed in current WBL development in the global context. It is through this unique approach that this paper increases the reader’s awareness of the limitations of current WBL practices, guides them to envision how to fully prepare and release the potential of the twenty-first century workforce, and calls for integrating or “meshing” CLM into the various Western approaches for a more holistic perspective for the possible transformation of current WBL practices worldwide.

Abstract

Purpose

The purpose of this paper is to provide a concise introduction of sustainability in human resource management (HRM) from the western perspective. With a review of Confucian thinking, it argues that the application of sustainability in HRM is more effective and efficient under the influence of Confucian values. Therefore, Chinese companies are likely ready to embrace the concept of sustainability and implement sustainable people management practices.

Design/methodology/approach

The paper is mainly theoretical in perspective. It also draws on semi-structured interview data derived from a study conducted in companies that operated in two cities in China: Guangzhou and Beijing to support the discussion of synergies between Confucian values and the western concept of sustainability in HRM.

Findings

In the interviews, it was evident that the interviewees were adhered to Confucian values, although they did not make the connection explicit. The interview data also showed how Confucian values (e.g. Ren, Yi, Li) affect Chinese management of human resources.

Research limitations/implications

The number of interviewees involved was not sufficient to allow a conclusive comparison between groups. Further research is needed to develop comparisons.

Practical implications

The paper suggests a favourable application of Confucian values in sustainable people management practices.

Originality/value

The interview data provide insight into how Confucian values lend support to sustainability in HRM.

Abstract

Purpose

The purpose of this paper is to apply rectangular Bézier surface patches directly into the mathematical formula used to solve boundary value problems modeled by Laplace's equation. The mathematical formula, called the parametric integral equation systems (PIES), will be obtained through the analytical modification of the conventional boundary integral equations (BIE), with the boundary mathematically described by rectangular Bézier patches.

Design/methodology/approach

The paper presents the methodology of the analytic connection of the rectangular patches with BIE. This methodology is a generalization of the one previously used for 2D problems.

Findings

In PIES the paper separates the necessity of performing simultaneous approximation of both boundary shape and the boundary functions, as the boundary geometry has been included in its mathematical formalism. The separation of the boundary geometry from the boundary functions enables to achieve an independent and more effective improvement of the accuracy of both approximations. Boundary functions are approximated by the Chebyshev series, whereas the boundary is approximated by Bézier patches.

Originality\value

The originality of the proposed approach lies in its ability to automatic adapt the PIES formula for modified shape of the boundary modeled by the Bézier patches. This modification does not require any dividing the patch into elements and creates the possibility for effective declaration of boundary geometry in continuous way directly in PIES.

Abstract

Purpose

The purpose of this paper is to link firms’ strategic archetypes as formulated by Miles and Snow (1978) to the more recent literature on organizational ambidexterity. Examining these obvious linkages, the paper also addresses how these firms address their entrepreneurial, engineering and administrative problem domains in relationship with the firm’s strategic archetype.

Design/methodology/approach

Data were collected from 503 firms across the US. Measures previously validated were used to collect information related to the strategic archetype as well as the three problem domains. Multiple discriminant and regression analyses were used to test the hypotheses.

Findings

Most of the hypotheses relating the entrepreneurial (exploration and exploitation), engineering (radical and incremental innovation) and administrative problem (adaptation and alignment) to the four strategic archetypes (defender, prospector, analyzer and reactor) were supported. Additionally, the authors found that the firms that had the closest alignment along the three problem domains outperformed the other firms.

Originality/value

Although the Miles and Snow typology has received considerable research attention, the obvious links with more contemporary research on organizational ambidexterity has been neglected. Through this integration, with more recent key strategic management concepts, this paper shows the utility and current relevance of the Miles and Snow archetypes.

Abstract

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract

Purpose

Detecting O2 gas in a confined space at room temperature is particularly important to monitor the work process of precision equipment. This study aims to propose a miniaturized, low-cost, mass-scale produced O2 sensor operating around 30°C.

Design/methodology/approach

The O2 sensor based on lanthanum fluoride (LaF3) solid electrolyte thin film was developed using MEMS technology. The principle of the sensor was a galvanic cell H2O, O2, Pt | LaF3 | Sn, SnF2 |, in which the Sn film was prepared by magnetron sputtering, and the LaF3 film was prepared by thermal resistance evaporation.

Findings

Through pretreatments, the sensor’s response signal to 40% oxygen concentration was enhanced from 1.9 mV to 46.0 mV at 30°C and 97.0% RH. Tests at temperatures from 30°C to 50°C and humidity from 32.4% RH to 97.0% RH indicated that the output electromotive force (EMF) has a linear relationship with the logarithm of the oxygen concentration. The sensitivity of the sensor increases with an increase in both humidity and temperature in the couple mode, and the EMF of the sensor follows well with the Nernst equation at different temperatures and humidity.

Practical implications

This research could be applied to monitor the oxygen concentration below 25% in confined spaces at room temperature safely without a power supply.

Originality/value

The relationship between temperature and humidity coupling and the response of the sensor was obtained. The nano-film material was integrated with the MEMS process. It is expected to be practically applied in the future.

Abstract

A new reverse educing method (REM) is presented to estimate the vibrational stress on rotating aeroengine blades from the actual fracture section. This method does not conform to the traditional calculating method, but involves the reverse solution idea. The value of the crack propagation ratio da/dN can be obtained from the actual fracture section of the blade, and then the vibrational stress on rotating blades can be calculated through static computation, modal analysis and crack stress intensity factor calculation. The result is very significant for fault diagnosing and shooting of aeroengine blades.
