Abstract

Purpose

This study aims to present a type of metamorphic mechanism-based quadruped crawling robot. The trunk design of the robot has a metamorphic mechanism, which endows it with excellent crawling capability and adaptability in challenging environments.

Design/methodology/approach

The robot consists of a metamorphic trunk and four series-connected three-joint legs. First, the walking and steering strategy is planned through the stability and mechanics analysis. Then, the walking and steering performance is examined using virtual prototype technology, as well as the efficacy of the walking and turning strategy.

Findings

The metamorphic quadruped crawling robot has wider application due to its variable trunk configuration and excellent leg motion space. The robot can move in two modes (constant trunk and trunk configuration transformation, respectively, while walking and rotating), which exhibits outstanding stability and adaptability in the examination and verification of prototypes.

Originality/value

The design can enhance the capacity of the quadruped crawling robot to move across a complex environment. The virtual prototype technology verifies that the proposed walking and steering strategy has good maneuverability and stability, which considerably expands the application opportunity in the fields of complicated scene identification and investigation.

Abstract

Purpose

Business has a critical part to play in transforming the global economy and society to achieve sustainable development. Many granular sustainability accounting and management tools have been offered. To systematize these piecemeal developments, this paper aims to develop a framework for analysis of the potential role of sustainability management accounting (SMA). The key challenge addressed is how SMA could be extended to support future-oriented, long-term, pro-active management of multiple issues to contribute towards strong sustainable development at the macro-economy level.

Design/methodology/approach

This conceptual paper examines SMA within a multi-level, context-action-transformation framework which can move organizations and society towards sustainability. Based on normative stakeholder theory, including concern for mainstreaming marginalized stakeholders, the paper discusses the role of SMA and how it can contribute necessary information to sustainable development of the company and beyond its boundaries.

Findings

Guided by a SMA framework linking context, action and transformation and normative stakeholder theory, which considers all stakeholders, the paper shows how the present lack of progress towards macro-level sustainable development can be addressed. This requires a focus on measuring and assessing positive impacts and forward-looking, long-term and proactive management of multiple sustainability issues as typified by the Sustainable Development Goals (SDGs).

Practical implications

The paper distinguishes between two aspects of SMA – a focus on reducing unsustainability and a focus on transformations towards sustainability. It is observed that there is insufficient emphasis on the latter at present if SMA is to provide comprehensive support to achieving the SDGs. A set of supportive tools is presented as a guide to practice and future developments.

Originality/value

The paper considers how SMA can enable and support transformations towards sustainability at the macro- and meso-level. Different transformational challenges and opportunities are discussed. In particular, the need to balance consideration of time, proactivity and multiplicity, as highlighted in the SDGs, is identified as the central way forward for SMA.

Abstract

Purpose

The study explores diverse and critical understandings of “international” in a higher education curriculum context, situated in a curriculum review of a postgraduate taught programme entitled “International Education” at a university located in England. Our study problematises and decentres some dominant, normalised notions of “international”, exploring critical possibilities of engaging with the term for higher education internationalisation.

Design/methodology/approach

We examined a set of programme curriculum documents and conducted a survey exploring teaching staff’s uses and interpretations of “international” in their design and delivery of course units. Through a thematic analysis of the dataset, we identify what “international” might mean or how it may be missing across the curriculum.

Findings

Our findings suggest a locally-developed conceptualisation of “international” beyond the normalised interpretation of “international” as the inclusion or comparison of multiple nations, and different, other countries around the global world. More diverse, critical understandings of the term have been considered, including international as intercultural, competences, ethics, languages and methods. The study provides an example approach to reflective scholarship that programmes can undergo in order to develop clarity, depth and purposefulness into internationalisation as enacted in a local curriculum context.

Originality/value

The study provides a first step towards establishing clearer guidelines on internationalising the curriculum by higher education institutions and individual programmes in order to challenge a superficial engagement of “international” within internationalisation. It exemplifies a starting point for making purposeful steps away from normalised notions and assumptions of international education and facilitates development towards its critical, ethically-grounded opportunities.

Abstract

Purpose

Because of the various advantages of reinforcement learning (RL) mentioned above, this study uses RL to train unmanned aerial vehicles to perform two tasks: target search and cooperative obstacle avoidance.

Design/methodology/approach

This study draws inspiration from the recurrent state-space model and recurrent models (RPM) to propose a simpler yet highly effective model called the unmanned aerial vehicles prediction model (UAVPM). The main objective is to assist in training the UAV representation model with a recurrent neural network, using the soft actor-critic algorithm.

Findings

This study proposes a generalized actor-critic framework consisting of three modules: representation, policy and value. This architecture serves as the foundation for training UAVPM. This study proposes the UAVPM, which is designed to aid in training the recurrent representation using the transition model, reward recovery model and observation recovery model. Unlike traditional approaches reliant solely on reward signals, RPM incorporates temporal information. In addition, it allows the inclusion of extra knowledge or information from virtual training environments. This study designs UAV target search and UAV cooperative obstacle avoidance tasks. The algorithm outperforms baselines in these two environments.

Originality/value

It is important to note that UAVPM does not play a role in the inference phase. This means that the representation model and policy remain independent of UAVPM. Consequently, this study can introduce additional “cheating” information from virtual training environments to guide the UAV representation without concerns about its real-world existence. By leveraging historical information more effectively, this study enhances UAVs’ decision-making abilities, thus improving the performance of both tasks at hand.

Abstract

Purpose

Engaging in international business (IB) is a particular challenge to small and medium-sized companies (SMEs), representing a condition to ensure growth and longevity. Due to their limitations of tangible resources, these companies make use of their levels of knowledge and capabilities to reach new markets. This study seeks to ascertain the role, the typologies of the knowledge and capabilities required for access to IB, and how benefits may arise for SMEs from their international experience.

Design/methodology/approach

To achieve these objectives, the authors ground the insights on a qualitative study that gathered data from ten semi-structured interviews with leading entrepreneurs engaged in IB. The data were analysed resorting to the QSR Nvivo software.

Findings

The results demonstrate how (1) knowledge and the development of dynamic capabilities all represent determinant facets to engaging in IB and that (2) the knowledge and learning capabilities acquired and developed in IB context also result in positive returns in domestic markets.

Originality/value

Despite the rising of IB studies, the interaction between knowledge and capabilities from the perspective of accessing international markets has not received attention enough from scholars. The authors argue that both constructs must act together to reach and maximize the IB of SMEs and provide evidence that engagement abroad brings several other advantages beyond economic returns.

Abstract

Purpose

Prior to 2020, University of California, Los Angeles (UCLA) Library's research services spanned multiple service points. Multiple locations were staffed by Library Student Research Assistants (LSRAs) and each location was supervised independently. While efforts to increase collaboration had been underway, much of the work and services remained siloed and often duplicated training and service hours.

Design/methodology/approach

With the onset of coronavirus disease 2019 (COVID-19), UCLA Library rapidly transitioned from entirely in-person to entirely online services. With multiple service points pivoting, UCLA was redundant to have multiple online desks providing Zoom appointments and that quickly became apparent. Moreover, transitioning in-person student work to remote work was paramount to providing both normal services to users and allowing LSRAs to keep jobs during a time of uncertainty and insecurity.

Findings

While the authors' original consolidation of services and implementation of shared supervision was a result of the pandemic and primarily involved online services, the authors have maintained this shared approach and collaborative vision in returning to in-person services. For the past year, the authors have offered shared in-person (at two library locations) and online services. As subject-specific library locations begin to reopen their desks, the authors continue to identify ways to leverage shared supervision and a robust referral model for those on-site services while negotiating student staffing and the need for both general and subject-specific services.

Originality/value

The authors present a novel approach to peer-to-peer teaching and learning and research services and shared student worker supervision with services coordinated across multiple locations and disciplines within a large academic library serving a large student population.
