Abstract

Purpose

This paper aims to focus on an assessment of the electrochemical corrosion performance of bulk NC copper in a variety of corrosion environments.

Design/methodology/approach

The electrochemical corrosion behavior of bulk nanocrystalline (NC) copper prepared by inert gas condensation and in situ warm compress technique was studied by using potentiodynamic polarization and electrochemical impedance spectroscopy tests in de-aerated 0.1 M NaOH solution.

Findings

NC copper exhibited a typical active-passive-transpassive behavior with the formation of duplex passive films, which was qualitatively similar to coarse-grain (CG) copper. Although a compact passive film formed on NC copper surface, the corrosion resistance of NC copper was lower in comparison with CG copper. The increase in corrosion rate for NC copper was mainly attributed to the high activity of surface atoms and intergranular atoms. These atoms led to an enhancement of passive ability and an increase of dissolution rate of passive film in oxygen-deficiency solution. For NC copper, the corrosion resistance decreased as grain size increased in NC range.

Originality/value

The difference in corrosion resistance between bulk NC copper and its CG counterpart is dependent upon the corrosion solution. In a previous work, the potentiodynamic polarization tests revealed that NC copper bulks (grain size 48, 68, 92 nm) had identical corrosion resistance to CG copper bulk in naturally aerated 0.1 M NaOH solution. The results might be related to the dissolved oxygen in the medium.

Abstract

For researchers and sector agencies around the world, poor academic integrity is seen as a significant risk to universities (Bretag & Harper, 2017; QAA, 2020; TEQSA, 2019). Given the existential threat that acts of academic misconduct are deemed to pose to higher education, interest in ways of developing academic integrity is correspondingly high and often invokes the concept of values (Macfarlane et al., 2014; Morris, 2018). However, to ascribe to academic integrity, the status of a self-evident, perhaps universal, value of contemporary higher education is contentious on many levels. This chapter takes in turn three of the most common ways in which students and scholars infringe on the principles of academic integrity – plagiarism, collusion, and contract cheating – and explores what the prohibiting of each of these acts reveals about the values of contemporary higher education. It argues that, far from neutral or universal, the values of academic integrity appear both normative and culturally specific, promoting a particular conception of higher education which risks excluding large sections of the global population. To counter this, the notion of threshold values – borrowing from Meyer and Land's (2005) notion of the “threshold concept” – is proposed, identifying the development of shared values as crucial to ensuring that contemporary, globalized universities are inclusive and accessible spaces.

Abstract

Purpose

Due to the vital role of frugal innovation (FI) for firms in developing and emerging economies, the purpose of this study is to investigate the effect of transformational leadership (TL) and knowledge sharing (KS) on FI of firms in supply chains. This study aims to bring deeper insight on the correlation among the constructs by exploring and analyzing the moderating effect of collaborative culture (CC) in the KS-FI relationship.

Design/methodology/approach

The paper used the quantitative approach and structural equation modeling (SEM) to test the relationship among the latent factors in the proposed research model using data collected from 381 participants in 116 manufacturing and service firms.

Findings

The findings revealed that TL might be an important precursor to induce significant influences on FI directly or indirectly through its effect on active and passive KS processes in supply chains. In addition, the paper highlights the moderating role of CC in strengthening the impact of KS processes on FI.

Research limitations/implications

The paper provides a valuable understanding and novel approach for managers to improve firms' FI capability through leadership practice and KS processes. The research findings support the idea that FI capability of firms in developing and emerging nations will be significantly enhanced if leaders are interested in practicing TL style and fostering a climate of collaboration within organization.

Originality/value

This study contributes to bridging research gaps in the literature and advancing the insights of how TL directly and indirectly fosters FI via mediating roles of active and passive KS processes in supply chains under the climate of collaboration.

Leadership development, career planning and management, management of start-ups, construction industry in India.

Abstract

Subject area

Leadership development, career planning and management, management of start-ups, construction industry in India.

Study level/applicability

Post graduate management courses, executive training programs/modules in leadership development; organizational culture and construction management.

Case overview

This case illustrates the shortcomings of both the management and leadership at a start-up business within a growing industry. The rapidly growing construction equipment manufacture and renting activity in India and the lack of structure, systems and resources characteristic of start-ups are complicated more by the fact that Itsun Heavy Industry India Pvt. Ltd (IHIIPL) was in India while its head quarter was in China. In exploring the diverse human, organizational and operational problems shadowing IHIIPL and their causes, students cannot only diagnose what went wrong and why for Dilip, but also sense how he could have handled these issues more effectively.

Expected learning outcomes

Dilip's case cautions managers against issues common to many industries and organizations and students will examine: self assessment and career choices: the case raises question of the gap between what was needed at IHIIPL and what skills and qualities Dilip brought to the job; leadership and leadership challenge: the case raises question of what kind of attitudes and actions constitute effective leadership; and managing the company performance for a start-up: Dilip faced a constant stream of operating problems: lack of procedures and systems, a non-supportive headquarter in China, inexperienced staff, shortages of resources and material and internal conflicts.

Abstract

Purpose

This paper aimed to examine the role of knowledge sharing among member enterprises between collaborative innovation activities and innovation performance and between building information modeling (BIM) application and innovation performance in the construction supply chain.

Design/methodology/approach

The structural equation model was used in this study. First, the hypothesis of the relationship between collaborative innovation activities, BIM application, knowledge sharing and innovation performance in the construction supply chain was proposed based on experience; then, the research data were collected by investigation; finally, this hypothesis was tested through data analysis.

Findings

(1) Collaborative innovation activities in the construction supply chain had a positive impact on explicit knowledge sharing, tacit knowledge sharing and innovation performance. (2) BIM application had a positive impact on explicit knowledge sharing and innovation performance, while it had no significant impact on tacit knowledge sharing. (3) Explicit knowledge sharing had no positive effect on innovation performance, while tacit knowledge sharing had positive effect on organizational performance. (4) Tacit knowledge sharing produced partial mediating effect between collaborative innovation activities, BIM application and innovation performance, while explicit knowledge sharing produced complete mediating effect between BIM application and tacit knowledge sharing.

Originality/value

A relationship model among collaborative innovation activities, BIM application, explicit and tacit knowledge sharing and innovation performance in the construction supply chain was proposed, and the rationality of the model was verified by empirical analysis. Discovering the relationships between these factors can be not only conducive to mastering the effect of explicit and tacit knowledge sharing in the collaborative innovation process of construction supply chain, but also play a guiding role for the function development of BIM.

Abstract

Purpose — In this paper we describe a total design data collection method (expanding the definition of the usual “total design” terminology used in typical household travel surveys) to emphasize the need to describe individual and group behaviors embedded within their spatial, temporal, and social contexts.

Methodology/approach — We first offer an overview of recently developed modeling and simulation applications predominantly in North America followed by a summary of the data needs in typical modeling and simulation modules for statewide and regional travel demand forecasting. We then proceed to describe an ideal data collection scheme with core and satellite survey components that can inform current and future model building. Mention is also made to the currently implemented California Household Travel Survey that brings together multiple agencies, modeling goals, and data collection component surveys.

Findings — The preparation of this paper involved reviewing emerging transportation modeling approaches and paradigms, policy questions, and behavioral issues and considerations that are important in the multimodal transportation planning context. It was found that many of the questions being asked of policy makers in the transportation domain require a deep understanding of the interactions and constraints under which individuals make activity-travel choices, the learning processes at play, and the attitudes and perceptions that shape ways in which people adjust their travel behavior in response to policy interventions. Based on the work, it was found that many of the traditional travel survey designs are not able to provide the comprehensive data needed to estimate activity-based model systems that truly capture the full range of behavioral considerations and phenomena of importance.

Originality/value of paper — This paper offers a review of the emerging transportation modeling approaches and behavioral paradigms of importance in activity-based travel demand forecasting. The paper discusses how traditional travel survey designs are inadequate to meet the data needs of emerging modeling approaches. Based on a review of all of the data needs and new data collection methods that are making it possible to observe a full range of human behaviors, the paper offers a total survey data collection design that brings together many different surveys and data collection protocols. The core household travel survey is augmented by a full slate of special purpose surveys that together yield a rich behavioral database for activity-based microsimulation modeling. The paper is a valuable reference for transportation planners and modelers interested in developing data collection enterprises that will feed the next generation of transportation models.

Abstract

Purpose

Implementation of research evaluation policies based on neoliberal orientations of performativity has transformed higher education institutions globally, reshaping academic work and the academic profession. Most lately, the mantra of “publish or no degree” has become the norm in many contexts. There has been little empirical research into the unintended consequences of this neoliberal academic performativity for inexperienced researchers. This article focuses on the role institutional research evaluation policies play on doctoral students and early-career doctoral graduates’ publication practices and on their decision to sometimes publish in journals with ethically “questionable” publishing standards in particular through the concept of figured worlds.

Design/methodology/approach

The study was conducted in a higher education setting employing a variety of research incentive schemes to boost research productivity where “publish or no degree” policy is the norm. It employs qualitative approach and involves in-depth interviews with nine doctoral students and seven early career academics who have been working part-time or full-time for five years following PhD completion.

Findings

Findings demonstrate publishing in journals with ethically “questionable” publishing standards is not always simply the result of naivety or inexperience. Some authors choose these journals in order to retain a sense of self-efficacy in the face of rejection by more highly ranked journals. Under institutional pressure to publish, they are socialized into this “shadow academia” through (existing) academic networks, conferences and journal special issues.

Originality/value

It is often assumed that scholars are trapped into “questionable” journals through the use of unsolicited emails. This paper challenges this assumption by demonstrating the crucial role research evaluation policies based on neoliberal orientations of performativity and contextual dynamics play on the publication practices of doctoral students and early-career doctoral graduates on their decision to submit to journals with “questionable” publication practices. It introduces the concept of unethical publication brokering, an informal network of ties promising fast and easy publication in outlets that “count”.

Abstract

Purpose

As Chinese massage is increasingly popular, many physicians are needed these days. In order to promote the experience and skills of experts and reduce labour intensity during massage, a massage robot, which could reproduce the expert techniques with individualized manipulation parameters and enhanced safety control strategies, is presented in this paper.

Design/methodology/approach

The kinematic and force features of key massage techniques, such as Thumb Kneading, Pressing, Rolling, Vibrating and Pinching, are summarized by analyzing the massage processes of expert physicians, and a mathematical model for robotic massage is established. With safety issues taken into account, the overall system structure of the massage robot is proposed. The system generally consists of a positioning platform and a massage end‐effector which implements the massage techniques, and the end‐effector is further divided into a parallel mechanism and a massage hand to accommodate different techniques. Visual tracking is used for positioning acupuncture points by recognizing markers on a massage vest worn by the patient. A pain threshold value is introduced to individualize therapy schemes and a force‐position control method based on the pain threshold is presented.

Findings

VAS (Visual Analogue Scale) tests for lumbar muscle strain are carried out using the massage robot, and the treatment effect of the massage robot based on traditional Chinese massage therapy theory is initially validated.

Research limitations/implications

The treatment effect of the massage robot needs to be assessed clinically for more occasions and more clinical experiments will be conducted, to optimize the configuration and control strategy to meet the clinical needs in future work.

Originality/value

The robotic massage system presented in this paper is acting on acupuncture points based on traditional Chinese massage therapy theory, with human manipulation techniques reproduced and expert experiences incorporated. The massage robot can take the place of a massager to perform Chinese massage. Most of the massage robotic systems published in the world perform only one massage technique and the whole massage process is not completely considered. By comparison, the authors' massage robot could perform five techniques. Furthermore, the authors have designed the procedure of robotic massage specifically for patients who suffer from lumbar muscle strain.

Abstract

Purpose

This paper aims to show how an Academic Literacies lens can contribute to a deeper understanding of writing for a professional doctorate (PD) by focusing both on the language of supervisors’ written feedback and on student and supervisor perspectives on feedback throughout Year 1 (Y1).

Design/methodology/approach

Firstly, written feedback summaries on formative assessments across two Y1 cohorts on a UK PD programme were analysed thematically to identify patterns in feedback practices. Secondly, two longitudinal, detailed student/supervisor case studies were developed, drawing on multiple data sources.

Findings

Supervisors’ written feedback enacted an encouraging dialogue around assessed writing, discursively constructing a sense of solidarity on the doctoral journey, focusing on the “long view”. Case study analysis, however, revealed tensions centred around jarring discontinuities in students’ feedback experience as they transitioned from formative to summative assessment at the end of Y1.

Research limitations/implications

The paper demonstrates that an Academic Literacies approach can offer valuable insights into the specific, situated context of writing for a distance learning PD and makes the case for greater attention to writing in contexts of partly taught doctorates.

Practical implications

Findings suggest that PD programmes should work towards providing continuity of feedback experience, through supervisor and examiner training and through assessment arrangements which support students to navigate challenging transitions between formative and summative phases of assessment.

Originality/value

This paper reports on an innovative research design which combined a textual “snapshot” of supervisory feedback, paying close attention to language, with detailed longitudinal case studies exploring perspectives on feedback over time. It contributes to doctoral writing research by throwing light on the relatively underexplored domain of writing in the taught phase of the PD. It contributes to doctoral education studies by highlighting the central role of feedback on writing in shaping the experience of PD researchers.
