The purpose of this study is to empirically evaluate the impacts of institutional pressures on the use of alternative maritime power (AMP) and which in turn enhance environmental performance in the maritime shipping context.

Factor analysis was used to identify the key coercive pressure, normative pressure, mimetic pressure, AMP practice and green performance dimensions. The author collects data from a survey of 184 maritime shipping operators in Taiwan and applies a structural equation modelling (SEM) to test the research hypotheses.

The findings show that AMP practice act as mediator variables between institutional pressures and environmental performance.

Theoretical contributions and managerial implications are drawn to help maritime shipping operators to improve environmental performance.

The purpose of this paper is to evaluate empirically the impact of intrafirm resources, interfirm relationships, and logistics service capabilities on logistics performance (LP) in the context of container logistics.

Factor analysis was employed to identify the key intrafirm resources (i.e. tangible assets and intangible assets), interfirm relationships (i.e. communication (COM) and long-term relationships), logistics service capabilities (i.e. service efficiency, service reliability, service flexibility, and value-added service), and LP dimensions. Data were collected from a survey of container shipping service providers, and were analyzed by a structural equation model to test the research hypotheses.

The findings show that interfirm relationships and logistics service capabilities act as mediator variables between intrafirm resources and LP.

The results of this research support the application of the general theory on firm-level performance and the resource-based view (RBV) as a lens through which LP can be achieved via logistics service capabilities. In addition, the findings lend empirical support to the capability-building view, which asserts the importance of resource investment and relationship maintenance, and the development of distinctive capabilities to enhance performance.

Container logistics operators should not view their intrafirm resources (including logistics information technology and teamwork organizational culture) or interfirm relationships (including informal COM with key stakeholders and evergreen relationship with key stakeholders) separately; instead, a systems approach should be used.

This research updates the RBV theory by clearly indicating that the overall performance of shipping firms cannot be decided solely by the firm’s own resources. Interfirm relationships and logistics service capabilities are found to be powerful moderators which help shipping firms allocate their resources effectively and thus improve their LP.

The purpose of this study is to empirically evaluate the impact of coercive pressure, normative pressure and mimetic pressure on digital transformation and benefits in the maritime shipping context.

The authors collect data from a survey of 119 shipping companies, shipping agencies, port corporations and shipping forwarders in Taiwan and apply a structural equation model to test the research hypotheses.

Four conclusions can be drawn: First, digital transformation mainly results from coercive pressure and mimetic pressure. Second, another positive and important source of pressure for shipping digital transformation is the fact that competitors are gradually undergoing digital transformation and have gained recognition from customers. Third, shipping professional organizations and association (e.g. IACS, IAPH, Baltic International Maritime Commission) must keep up with the trend toward digital transformation and put forward guidelines and recommendations that can be followed in order to lead the maritime shipping industry. Fourth, digital transformation has great potential to help deliver the benefits (i.e. improve efficiency, relationship with customers and sustainability).

This research explores the digital transformation of the shipping industry through the lens of institutional theory. The results show that digital transformation is mainly due to coercive pressure and mimetic pressure. Digital transformation has been found to bring benefits that can help shipping operators allocate their resources effectively, thereby increasing operational efficiency, improving relationships with customers and enhancing sustainability.

This work experimentally and numerically investigates the aerodynamic heating of the charring‐ablating materials.

The experimental model is a stainless steel cone with an attached charring ablator, in which supersonic hot flow impinges. The initial numerical simulation is based on physical and mathematical models, including one‐dimensional, unsteady energy transport and mass conservation equations, coupled with calculations of aerodynamic heating, thermal degradation, heat transfer of the ablating surface and the ablation model. The problem is solved by an efficient numerical method.

The numerical calculations involve the time history of the temperature distribution inside the charring material and the backup structure. The results are consistent with the experimental data.

This study proposes an effective method to correlate one's own ablation rate equation, by a method of trial and error to find the correlation constants, and the corresponding time histories of the ablation rate or temperature that are closest to one's own experimental data. Then the correlation of the surface ablation rate can be applied with confidence in the numerical calculation of other cases.

The purpose of this paper is to empirically examine the relationships among supply chain integration (SCI), supply chain service capabilities, market performance (MP), and financial performance (FP) in the container shipping context and develops valid and reliable instruments for future research.

A structured questionnaire was used to gather data from 133 container shipping operators and agencies in Taiwan, using confirmatory factor analysis, the author identified main dimensions of SCI and supply chain service capabilities in container shipping context. A structural equation model was then used to test the research hypotheses.

This study has identified a set of five dimensions that can enable effective SCI: top management support, cross-functional cooperation, information technology, goal congruence, and collaborative communication, and highlighted the critical mediating role of supply chain service capabilities (i.e. service efficiency, service reliability, service flexibility, and value-added service) in improving firms’ market and FP. The authors confirm that SCI has a positive impact on supply chain service capabilities, which in turn helps to enhance market and FP.

This research can thus serve as a valuable reference for managers to achieve better SCI formation and performance, help managers to develop more effective collaborative relationships, and thus minimize the chance of SCI failure.

This manuscript provides a theoretical framework to link SCI, supply chain service capabilities, MP, and FP for the container shipping service supply chain context that have not been previously reported through empirical research.

Organisations and industries are often looking for technologies that can accomplish multiple tasks, providing economic benefits and an edge over their competitors. In this context, drones have the potential to change many industries by making operations more efficient, safer and more economic. Therefore, this study investigates the use of drones as the next step in smart/digital warehouse management to determine their socio-economic benefits.

The study identifies various enablers impacting drone applications to improve inventory management, intra-logistics, inspections and surveillance in smart warehouses through a literature review, a test of concordance and the fuzzy Delphi method. Further, the graph theory matrix approach (GTMA) method was applied to ranking the enablers of drone application in smart/digital warehouses. In the subsequent phase, researchers investigated the relation between the drone application's performance and the enablers of drone adoption using logistic regression analysis under the TOE framework.

This study identifies inventory man agement, intra-logistics, inspections and surveillance are three major applications of drones in the smart warehousing. Further, nine enablers are identified for the adoption of drone in warehouse management. The findings suggest that operational effectiveness, compatibility of drone integration and quality/value offered are the most impactful enablers of drone adoption in warehouses. The logistic regression findings are useful for warehouse managers who are planning to adopt drones in a warehouse for efficient operations.

This study identifies the enablers of drone adoption in the smart and digital warehouse through the literature review and fuzzy Delphi. Therefore, some enablers may be overlooked during the identification process. In addition to this, the analysis is based on the opinion of the expert which might be influenced by their field of expertise.

By considering technology-organisation-environment (TOE) framework warehousing companies identify the opportunities and challenges associated with using drones in a smart warehouse and develop strategies to integrate drones into their operations effectively.

This study proposes a TOE-based framework for the adoption of drones in warehouse management to improve the three prominent warehouse functions inventory management, intra-logistics, inspections and surveillance using the mixed-method.

The purpose of this paper is to study the influence of number of feeding holes on the performance of aerostatic bearings with spindle rotation. In traditional design of aerostatic bearings, the selection of hole numbers is dependent only on spindle size. However, when the hole numbers of air feeding are enough, the performance of the aerostatic bearing cannot be enhanced by increasing the hole numbers.

The Reynolds equation is utilized to model the air film within bearing clearance at constant temperature and the state equation of adiabatic process is for air feeding within bearing clearance. The finite difference method with relaxation algorithm is utilized to determine the pressure distributions from discretized and coupled equations of flow continuity. The eccentricity, spindle speed, and the number and arrangement of feeding holes are considered in the analyses to determine the load capacity, attitude angle, and flow rate for the comparisons between various designs of aerostatic bearings.

It is seen from the simulation results that the aerostatic bearing designed with a small number of feeding holes and without locating at bearing bottom is most suitable for the spindle operating at high speed, while the bearing designed with a large number of feeding holes is suitable for the spindle operating at low speed, and the load capacity is increased with the increasing number of feeding holes for low journal speed.

The paper proposes an extensive database as a critical requirement in the design for number and arrangement of feeding holes of aerostatic bearings for the spindle operating at low or high speed.

All deep‐groove ball bearings have similar features in geometry, mechanism, and structure. Stiffness of this type of bearings is related to geometry, dimensions, and operating conditions by a very complex, high‐order and coupled‐variable function. This paper has verified that the stiffness function for all deep‐groove ball bearings can be replaced by a back‐propagation neural network (BPNN) which is trained by using some (not all) samples.

Previous studies of e-servicescapes have considered general internet consumers as the main research subjects; however, some studies have argued that heavy users are the main sources of consumption. Understanding heavy user’s consumption traits is crucial for enhancing company profits; hence, the purpose of this paper is to compare the significant attributes of e-servicescapes and clarify their relationship with purchase intention by employing heavy and light internet users as moderators.

An online questionnaire was used to collected data from 342 valid internet users with online shopping experience, and the differences were compared through structural equation modeling.

Aesthetic appeal and interactivity significantly increase general users’ purchase intentions. For heavy users, interactivity was the most crucial factor, followed by esthetic appeal, and then layout and functionality. For light users, Aesthetic appeal was the only crucial factor. The data also reveal that financial security does not have significant positive effects on general, heavy, or light users.

Using the insight gained by integrating purchase intention with e-service quality and segmentation theory in the e-servicescape, the authors display how heavy and light internet users evaluate the e-servicescape for signals of quality attributes and contribute their cognitive response and purchase intention according to different consumption traits. Internet retailers are recommended to segment heavy and light users, redesign their current e-servicescapes, and provide more appropriate marketing strategies to attract and keep heavy and light users and enhance their purchase intentions.

Visually impaired people have long been living in the dark. They cannot realize the colorful world with their vision, so they rely on hearing, touch and smell to feel the space they live in. Lacking image information, they face challenges in the external environment and barrier spaces. They face danger that is hundreds of times higher than that faced by normal people. Especially during outdoor activities, they can only explore the surrounding environment aided by their hearing and crutches and then based on a vague impression speculate where they are located. To let the blind confidently take each step, this paper proposes sticking the electronic tag of the radio-frequency identification (RFID) system on the back of guide bricks.

Thus, the RFID reader, ultrasonic sensor and voice chip on a wheeled mobile robot link the front end to the crutch. Once the blind person nears a guide brick, the RFID will read the message on the tag through the voice broadcast system, and a voice will inform the visually impaired person of the direction to walk and information of the surrounding environment. In addition, the CMOS image sensor set up in the wheeled mobile robot is used to detect the black marking on the guide brick and to guide the blind to walk forward or turn around between the two markings. Finally, the lithium battery charging control unit was installed on the wheeled mobile robot. The ATtiny25 microcontroller conducts the battery charge and discharge control and monitoring of the current battery capacity.

The development of this system will let visually impaired people acquire environmental information, road guidance function and nearby traffic information.

Through rich spatial environment messages, the blind can have the confidence and courage to go outside.
