Abstract

Purpose

The paper explores and characterizes antifragility in simple inventory systems exposed to demand variability, providing the initial inroads to operationalizing antifragility in the context of inventory management. Antifragility refers to the feature of a system that can benefit from uncertainty, rather than suffer from it. The paper expands the concept of inventory beyond that of risk mitigation and towards one of enabling antifragility.

Design/methodology/approach

The study employs analytical and simulation modelling of an inventory system with two classes of demand. To separate the influence of factors, a simple inventory policy with a range of fixed order quantities is modelled, allowing for the identification of antifragile regions in an experimental space.

Findings

Outputs uncover a variety of performance outcomes, ranging from settings where additional inventory yields no benefit, to areas where additional inventory results in increasing normalized profit with increasing uncertainty, demonstrating antifragility. In between these regions, increases in normalized profit are bounded, and confined to specific regions.

Research limitations/implications

This research expands academic understanding of inventory as a vehicle to achieving antifragile outcomes. Although this paper does not solve for an optimal policy as typical inventory research does, it instead characterizes the antifragile outcomes within simple inventory systems. Further research should be carried out to investigate antifragility in settings of greater complexity and design ordering policies leveraging inventory towards a gain from uncertainty.

Practical implications

Typically, inventory is used to buffer against uncertainty, and, with a given amount of inventory, the performance is expected to degrade with increasing variability. In this paper, the authors demonstrate that certain levels of additional inventory can result in antifragility and increase profitability as uncertainty increases, extending beyond traditional conceptualizations of inventory and uncertainty.

Originality/value

Empirical research into designing antifragile outcomes is limited, with very few examples of increasing performance with increases in uncertainty. This article presents an initial empirical exploration of how additional inventory can result in antifragility.

Abstract

Reports a study of 1,304 Chinese brand names of ten types of products in China. These brand names are content analyzed following a linguistic approach which the authors developed from their earlier studies. The ten types of brand names are presented in three broad categories representing the three different developing stages of the consumer product industry in China: brands of traditional products (illustrated by matches and spirits), brands of traditional products with current development (illustrated by bicycles, shoes, and toothpastes), and brands of new and modern products (illustrated by cosmetics, soft drinks, washing machines, refrigerators and TV sets). The conclusion drawn from the analysis is that one of the variables in determining how linguistic principles are being applied to Chinese brand naming is the respective stages of development of such products in the context of the Chinese market economy.

Abstract

Purpose

This paper aims to provide an integrated BIM-based approach for quantity take-off for progress payments in the context of high-rise buildings in Vietnam. It tries to find answers for the following questions: (1) When to start the QTO processes to facilitate the contract progress payments? (2) What information is required to measure the quantity of works to estimate contract progress payment (3) What are the challenges to manage (i.e. create, store, update and exploit)? What are the required information for this BIM use? and (4) How to process the information to deliver BIM-based QTO to facilitate contract progress payment?

Design/methodology/approach

The paper applied a deductive approach and expert consensus through a Delphi procedure to adapt to current innovation around BIM-based QTO. Starting with a literature review, it then discusses current practices in BIM-based QTO in general and high-rise building projects in particular. Challenges were compiled from the previous studies for references for BIM-based QTO to facilitate contract progress payment for high-rise building projects in Vietnam. A framework was developed considering a standard information management process throughout the construction lifecycle, when the BIM use of this study is delivered. The framework was validated with Delphi technique.

Findings

Four major challenges for BIM-based QTO discovered: new types of information required for the BIM model, changes and updates as projects progress, low interoperability between BIM model and estimation software, potentiality of low productivity and accuracy in data entry. Required information for QTO to facilitate progress payments in high-rise building projects include Object Geometric/Appearance Information, Structural Components' Definition and Contextual Information. Trade-offs between “Speed – Level of Detail–Applicable Breadth” and “Quality – Productivity” are proposed to consider the information amount to input at a time when creating/updating BIM objects. Interoperability check needed for creating, authoring/updating processing the BIM model's objects.

Research limitations/implications

This paper is not flawless. The first limitation lies in that the theoretical framework was established only based on desk research and small number of expert judgment. Further primary data collection would be needed to determine exactly how the framework underlies widespread practices. Secondly, this study only discussed the quantity take-off specifically for contract progress payment, but not for other purposes or broader BIM uses. Further research in this field would be of great help in developing a standard protocol for automatic quantity surveying system in Vietnam.

Originality/value

A new theoretical framework for BIM-based QTO validated with Delphi technique to facilitate progress payments for high-rise building projects, considering all information management stages and the phases of information development in the project lifecycle. The framework identified four types of information required for this QTO, detailed considerations for strategies (Library Objects Development, BIM Objects Information Declaration, BIM-based QTO) for better managing the information for this BIM use. Two trade-offs of “Speed – LOD–Applicable Breadth” and “Quality – Productivity” have been proposed for facilitating the strategies and also for enhancing the total efficiency and effectiveness of the QTO process.

Abstract

Over the past several decades, scholars and universities have made efforts to increase the retention of students in higher education, but graduation rates remain low. Whereas two-thirds of high school graduates attend college, fewer than half graduate. The likelihood of graduation decreases even more for Black, Latino, American Indian, and low-income students, who have a 12–15% lower chance of earning their degree. The importance of psychosocial adjustment to student persistence has received relatively less attention than academic and social integration. Racial/ethnic minority students face unique challenges to psychosocial adjustment in college, including prejudice and discrimination, unwelcoming campus environments, underrepresentation, and a lack of culturally appropriate counseling resources. The current chapter will discuss the impact of these challenges on the persistence, academic success, and health of racial/ethnic minority students, and strategies that universities can employ to create inclusive policies, resources and campus environments that empower students of color and maximize their success.

Abstract

Purpose

The paper seeks to attempt to solve a decision‐making problem for breeding target character shown as an interval number.

Design/methodology/approach

A new comprehensive evaluation method is proposed based on similarity‐difference theory and interval number theory. Data from Winter Wheat Group I Variety Regional Test in Henan Province in 2009‐2010 were analysed using the proposed method.

Findings

The results showed that Zhou 99233 was a good variety; Yuxhan No. 7, An 05‐28, Xun K8, Jinyumai 378 and Zhoumai 18 were better ones; 08 luo 36,and Xuke 718 ordinary ones, and others worse ones. Based on this, the feasibility of the method was discussed. It showed that the proposed method had some obvious merits, such as simple arithmetic, convenient operation, flexible and practical, fast and effective.

Practical implications

The application of a live example indicated that its evaluation effect was satisfactory.

Originality/value

The paper succeeds in solving a decision‐making problem for breeding target character shown as an interval number.

Abstract

Purpose

This study aims to investigate how the frame orientation format and visual content of tourism short videos interact to influence tourists’ travel intention.

Design/methodology/approach

Two scenario-based experiments were designed and conducted through Credamo. The researchers enrolled 187 participants for Study 1 using convenience sampling, measuring the impact of video frame orientation and visual content on travel intention by conducting a two-factor analysis of covariance. Study 2 retested the interaction effect using 237 sample data and conducted bootstrapping to examine the serially mediating effect of imagery fluency and travel inspiration.

Findings

Frame orientation formats and visual content interactively affect the video audience’s travel intention: For site-centric tourism short videos, the horizontal frame orientation format can help inspire audiences’ travel intention; However, for activity-centric tourism short videos, the vertical frame orientation format is more suitable. Imagery fluency and travel inspiration have serially mediated effects in the above interactions.

Practical implications

Destination marketers can use a combination of vertical format and activity-centric content (or horizontal format and site-centric content) to ensure the marketing effectiveness of short videos.

Originality/value

This study explores how frame orientation and visual content interact to influence video audiences’ travel intention. The findings challenge the traditional understanding of frame orientation selection in short videos, provide a meaningful extension of construal-level theory and contribute to the research on visual effects in short tourism videos.

Propósito

Este estudio investiga cómo el formato de orientación del marco y el contenido visual de los vídeos cortos turísticos interactúan para influir en la intención de viaje de los turistas.

Diseño/metodología/enfoque

Se diseñaron y llevaron a cabo dos experimentos basados en escenarios a través de Credamo. Los investigadores reclutaron a 187 participantes para el Estudio 1 mediante un muestreo de conveniencia, y midieron el impacto de la orientación del fotograma de vídeo y el contenido visual en la intención de viajar realizando un análisis de covarianza de dos factores. El Estudio 2 volvió a probar el efecto de interacción utilizando 237 datos de muestra y realizó bootstrapping para examinar el efecto de mediación en serie de la fluidez de las imágenes y la inspiración para viajar.

Conclusiones

Los formatos de orientación de los fotogramas y el contenido visual influyen de forma interactiva en la intención de viajar del público del vídeo: Para los vídeos turísticos de corta duración centrados en un lugar, el formato de orientación horizontal puede ayudar a inspirar la intención de viajar del público; sin embargo, para los vídeos turísticos de corta duración centrados en una actividad, el formato de orientación vertical es más adecuado. La fluidez de las imágenes y la inspiración para viajar tienen efectos mediados en serie en las interacciones mencionadas.

Implicaciones practices

Los responsables de marketing de destinos pueden utilizar una combinación de formato vertical y contenido centrado en la actividad (o formato horizontal y contenido centrado en el sitio) para garantizar la eficacia de marketing de los vídeos cortos.

Originalidad/valor

Este estudio explora cómo la orientación del encuadre y el contenido visual interactúan para influir en la intención de viaje de los espectadores de vídeos. Los resultados cuestionan la interpretación tradicional de la selección de la orientación del encuadre en los vídeos cortos, proporcionan una ampliación significativa de la teoría del nivel de construcción y contribuyen a la investigación sobre los efectos visuales en los vídeos turísticos cortos.

Abstract

Purpose

This paper aims to design a novel hybrid terrestrial-aerial robot, FlyingDog, including its modeling and implementation. By combining the complementary advantages of a quadrotor drone and a quadruped robot, FlyingDog demonstrates excellent maneuverability and high energy efficiency, showcasing great potential for applications in industrial inspection, field exploration, and search and rescue operations.

Design/methodology/approach

By integrating propellers and leg mechanisms, FlyingDog achieves hybrid motion, encompassing both aerial flight and ground movement. This paper first provides an overview of the robot’s structural design, emphasizing the minimization of interactions between the aerial and ground mechanisms while balancing the thrust-to-weight ratio and payload capacity. A distributed control framework is then proposed to achieve the hybrid motion, alongside the development of corresponding control strategies to ensure stability during various movements.

Findings

Experiments conducted in real-world conditions validated FlyingDog’s performance in terms of motion stability, energy efficiency, and obstacle-crossing ability. The results demonstrate that FlyingDog exhibits outstanding mobility by combining ground locomotion with aerial flight capabilities, allowing it to overcome challenging obstacles in purely ground-based mode. In ground mode, the robot achieved an energy efficiency of up to 93.5%.

Originality/value

The hybrid terrestrial-aerial robot presented in this paper features stable land and aerial mobility, a lightweight structure, high energy efficiency, and low manufacturing costs, making it a valuable innovation in the field of robotics.

Abstract

The role of the university in the 21st century is rapidly changing, reflecting a growing interest in the commercialisation of university knowledge among scholars and policymakers. University spin-offs (USOs) represent one mechanism for commercialising knowledge that are attracting considerable attention because of their potential to (a) enhance local economic development, (b) assist universities in their major mission of teaching and research and (c) generate high-performance firms (Shane, 2004). Indeed, one study by Bray and Lee (2000), based on a small US sample, found that on average, technology transfer offices earned a higher return from equity stakes in their USOs, even allowing for a 50% failure rate, than from the average licensing agreement.

Abstract

Immigrant groups often pursue entrepreneurial endeavors in their new home country. Even though both immigrant entrepreneurship and organizational identity have received scholarly attention, there has been little systematic exploration of identity strategies pursued by immigrant-owned organizations. In this article, we develop a theoretical framework that draws on the concepts of liability of foreignness and social identity theory in the context of immigrant entrepreneurship. Our framework explores how immigrant entrepreneurs may negotiate identities for their firms through the development of specific identity strategies that confirm or underplay their national/ethnic identities in order to survive in their immediate environment. We develop a model that shows how these confirmations or underplaying strategies work both for firms that have an individualistic entrepreneurial orientation, as well as those with a collective/associative entrepreneurial orientation. We also suggest two contextual moderators to this relationship: (1) the image of the founder's country of origin, and (2) the presence of immigrant networks in the host country, which may alter the effectiveness of identity strategies in terms of organizational mortality outcomes.
