Abstract

Purpose

The purpose of this paper is to compare two mediating mechanisms of servant leadership’s effect on followers’ work engagement: the social exchange mechanism (represented by leader-member exchange (LMX)) and the social learning mechanism (represented by public service motivation in Study 1 and prosocial motivation in Study 2).

Design/methodology/approach

In Study 1, the authors collected two-wave matched data from 216 public sector employees. In Study 2, the authors collected two-wave matched data from 178 private sector employees. The authors use hierarchical regression and bootstrapping to test the hypotheses.

Findings

Servant leadership is positively related to follower’s work engagement and this relationship is mediated by LMX, but not by public service motivation (Study 1) or prosocial motivation (Study 2). It suggests that servant leadership promotes followers’ work engagement mostly through the social exchange mechanism.

Research limitations/implications

The data were collected from Chinese employees, and future studies are necessary to verify the findings in other cultural contexts.

Originality/value

This study sheds light on a more nuanced picture of the effect mechanisms of servant leadership.

Abstract

Purpose

This study discusses the tracking trajectory issue of the exoskeleton under the bounded disturbance and designs an useful tracking trajectory control method to solve it. By using the proposed control method, the tracking error can be successfully convergence to the assigned boundary. Meanwhile, the chattering effect caused by the actuators is already reduced, and the tracking performance of the pneumatic artificial muscles (PAMs) elbow exoskeleton is improved effectively.

Design/methodology/approach

A prescribed performance sliding mode control method was developed in this study to fulfill the joint position tracking trajectory task on the elbow exoskeleton driven by two PAMs. In terms of the control structure, a dynamic model was built by conforming to the adaptive law to compensate for the time variety and uncertainty exhibited by the system. Subsequently, a super-twisting algorithm-based second-order sliding mode control method was subjected to the exoskeleton under the boundedness of external disturbance. Moreover, the prescribed performance control method exhibits a smooth prescribed function with an error transformation function to ensure the tracking error can be finally convergent to the pre-designed requirement.

Findings

From the theoretical perspective, the stability of the control method was verified through Lyapunov synthesis. On that basis, the tracking performance of the proposed control method was confirmed through the simulation and the manikin model experiment.

Originality/value

As revealed by the results of this study, the proposed control method sufficiently applies to the PAMs elbow exoskeleton for tracking trajectory, which means it has potential application in the actual robot-assisted passive rehabilitation tasks.

Abstract

Purpose

The poor corrosion resistance of the ferrite-pearlite steel limits its application in marine engineering because of the enhanced galvanic effect caused by continuously accumulated cementite. Cr as one principal alloying element is commonly used to improve the corrosion resistance of steels. This paper aims to study the effect of Cr on corrosion behaviors of ferrite-pearlite steels in an acidic environment.

Design/methodology/approach

The tested steels were immersed in a simulated solution of 10 Wt.% NaCl with pH 0.85 for 72 h to evaluate the corrosion rate. After the immersion test, the corrosion morphologies and products were tested by scanning electron microscopy, energy dispersive X-ray analysis and X-ray diffraction. Meanwhile, an electrochemical workstation was used to study the electrochemical behaviors of samples.

Findings

At the initial corrosion stage, the corrosion rate increased in the sequence of Cr0, Cr0.5 and Cr1 steels, which was because of the competitive effect between the area ratio and the driving force caused by alloyed Cr. However, Cr1 steel exhibited the best corrosion resistance after a 72-h immersion test. This was because the alloyed Cr promoted the formation of protective Fe2O3 and FeCr2O4, which suppressed the preferential dissolution of ferrite and, thus, reduced the accumulation rate of carbides, resulting in the weakened galvanic corrosion.

Originality/value

This paper reports the role that Cr plays in the galvanic corrosion of ferrite-pearlite steels, which is important for the engineering application of ferrite-pearlite steels in marine environment.

Abstract

One hundred and seventy‐eight heroin addicts in reformatory school were sent to one of two rehabilitation treatments: reform through education and labour and therapeutic community (TC)‐based rehabilitation programme. After six months of being discharged, pre‐ and post‐treatment scores on the Addiction Severity Index were compared, and relapse related factors were investigated. Results indicated improvements in both treatments, with the TC‐based rehabilitation programme showing superior improvement overall. Results support the efficacy of the TC‐based rehabilitation programme proving it to be better than reform through labour and education. It is suggested that psychosocial intervention and relapse prevention should be emphasised in the treatment of drug dependence.

Abstract

Purpose

Based on the knowledge-based view (KBV), the purpose of this study is to explore the impact of scientific knowledge resources on innovative performance, as well as the mechanisms, in the science-based innovation practice of biotechnological industry. How scientific knowledge influences the firms’ innovative performance and how external scientific knowledge flows into the firms efficiently are important issues every high-tech firms must consider.

Design/methodology/approach

The authors chose biopharmaceutical firms in China as the sample of this study to empirically test the hypotheses.

Findings

The study introduces a framework combining scientific knowledge resources, technological capabilities and innovative performance and, then, follows with an empirical investigation on firms in Chinese biotechnological industry. Survey data from biopharmaceutical firms in China prove the significantly positive impact of both stocks and flows of scientific knowledge on firms’ innovative performance, as well as the significant mediation effect, of technological capability.

Practical implications

From the results of this study, the authors derive the important managerial implications that talent exchange, purchasing external knowledge directly and establishing R&D alliances are three effective ways leading external scientific knowledge to flow into the firms.

Originality/value

The study finds that technological capability plays an intermediary role between scientific knowledge resource and innovative performance; tacit scientific knowledge stock and R&D alliance influence innovative performance through technological capability totally among them.

Abstract

Purpose

The Internet of Things (IoT) offers substantial potential for improving efficiency and effectiveness in various applications, notably within the domain of smart construction. Despite its growing adoption within the Architecture, Engineering, and Construction (AEC) industry, its utilization remains limited. Despite efforts made by policymakers, the shift from traditional construction practices to smart construction poses significant challenges. Consequently, this study aims to explore, compare, and prioritize the determinants that impact the acceptance of the IoT among construction practitioners.

Design/methodology/approach

Based on the integrated model of Unified Theory of Acceptance and Use of Technology (UTAUT2), Task-Technology Fit (TTF), and perceived risk. A cross-sectional survey was administered to 309 construction practitioners in China, and the collected data were analyzed using structural equation modeling (SEM) to test the proposed hypotheses.

Findings

The findings indicate that TTF, performance expectancy, effort expectancy, hedonic motivation, facilitating conditions, and perceived risk exert significant influence on construction practitioners’ intention to adopt IoT. Conversely, social influence and habit exhibit no significant impact. Notably, the results unveil the moderating influence of gender on key relationships – specifically, performance expectancy, hedonic motivation, and habit – in relation to the behavioral intention to adopt IoT among construction practitioners. In general, the model explains 71% of the variance in the behavioral intention to adopt IoT, indicating that the independent constructs influenced 71% of practitioners’ intentions to use IoT.

Practical implications

These findings provide both theoretical support and empirical evidence, offering valuable insights for stakeholders aiming to gain a deeper understanding of the critical factors influencing practitioners’ intention to adopt IoT. This knowledge equips them to formulate programs and strategies for promoting effective IoT implementation within the AEC field.

Originality/value

This study contributes to the existing literature by affirming antecedents and uncovering moderators in IoT adoption. It enhances the existing theoretical frameworks by integrating UTAUT2, TTF, and perceived risk, thereby making a substantial contribution to the advancement of technology adoption research in the AEC sector.

Abstract

Purpose

The purpose of this paper is twofold: first, to assess the impact of the 1999 Special Issue on Professionalization in Asia in the Accounting, Auditing and Accountability Journal (AAAJ); and second, more generally to review research on this topic post-1999.

Design/methodology/approach

The paper starts with a discussion of the research articles of the Special Issue. It then identifies research that has cited papers in the Special Issue and which focusses on professionalization in Asia to identify relevant subsequent research. In addition, a literature search is conducted to locate post-1999 work that has not cited papers from the Special Issue but has investigated the same topic area. Analyzing both sets of work enables an integrated review of the field and aids the identification of future research opportunities. The study covers published research articles and books on professionalization projects in Asia from 1999 to 2018. In this paper, reference to Asia focusses on East Asia (including countries such as China and Japan), South Asia (including countries such as Bangladesh, India and Sri Lanka), and South East Asia (including countries such as Brunei, Cambodia, Indonesia, Malaysia, the Philippines and Vietnam). Given the elapsed time of near 20 years, there has been sufficient time for research to be published. Therefore, the review focusses on published output only and does not discuss unpublished theses, conference proceedings nor working papers.

Findings

First, the Special Issue of AAAJ in 1999 generally adopted a critical lens and studied professionalization as projects of market closure and collective mobility. The corporatist framework of Puxty et al. (1987) provided a useful framing to analyze the influence of states, markets and communities on professionalization. Second, the Special Issue has helped to spur interest in understanding professionalization in the region. Post-1999, there are studies of countries not covered in the Special Issue. Third, the themes identified in the Special Issue continue to be relevant and are examined in post-1999 work: the active role of the state, the legacies of colonization, the activities of transnational accounting bodies; and to a lesser degree, the influence of transnational accounting firms. Finally, future research could usefully focus on: the distinctive and more expansive role of Asian state agencies; the conduct of deeper comparative research; the role of accounting firms in the region; and the impact of transnational agencies such as the International Federation of Accountants and the World Bank.

Research limitations/implications

There are three limitations. First, the review of literature omits unpublished research such as PhD theses and working papers. Second, it focusses only on research published in English. As a result, some work may be excluded. Third, it assesses the contribution of a single issue (i.e. the 1999 AAAJ Special Issue) and does not discuss work that preceded 1999.

Originality/value

This paper is aimed at assessing the impact of the 1999 Special Issue but also presents a wide-ranging analytical review of published research on accounting professionalization in Asia since 1999. The paper identifies several areas for future research and proposes a modified model of state-market-community-profession relations. In particular, the paper emphasizes the large and distinctive roles of Asian state agencies and the activities of transnational actors (both those within the profession as well as those that are external).

Abstract

Purpose

Polyaniline (PANI) has garnered attention for its potential applications in anticorrosion fields because of its unique properties. Satisfactory outcomes have been achieved when using PANI as a functional filler in organic coatings. More recently, research has extensively explored PANI-based organic coatings with self-healing properties. The purpose of this paper is to provide a summary of the active agents, methods and mechanisms involved in the self-healing of organic coatings.

Design/methodology/approach

This study uses specific doped acids and metal corrosion inhibitors as active and self-healing agents to modify PANI using the methods of oxidation polymerization, template synthesis, nanosheet carrier and nanocontainer loading methods. The anticorrosion performance of the coatings is evaluated using EIS, LEIS and salt spray tests.

Findings

Specific doped acids and metal corrosion inhibitors are used as active agents to modify PANI and confer self-healing properties to the coatings. The coatings’ active protection mechanism encompasses PANI’s own passivation ability, the adsorption of active agents and the creation of insoluble compounds or complexes.

Originality/value

This paper summarizes the active agents used to modify PANI, the procedures used for modification and the self-healing mechanism of the composite coatings. It also proposes future directions for developing PANI organic coatings with self-healing capabilities. The summaries and proposals presented may facilitate large-scale production of the PANI organic coatings, which exhibit outstanding anticorrosion competence and self-healing properties.

Abstract

Purpose

Fabrics with photothermal conversion functions were developed based on the introduction of shape stable composite phase change materials (CPCMs).

Design/methodology/approach

Acidified single-walled carbon nanotubes (SWCNTs) were selected as support material to prepare CPCMs with n-octadecane to improve the thermal conductivity and shape stability. The CPCMs were finished onto the surface of cotton fabric through the coating and screen-printing method. The chemical properties of CPCMs were characterized by Fourier transform infrared spectrometer, XRD and differential scanning calorimetry (DSC). The shape stability and thermal conductivity were also evaluated. In addition, the photothermal conversion and temperature-regulating performance of the finished fabrics were analyzed.

Findings

When the addition amount of acidified SWCNTs are 14% to the mass of n-octadecane, the best shape stability of CPCMs is obtained. DSC analysis shows that the latent heat energy storage of CPCMs is as high as 183.1 J/g. The thermal conductivity is increased by 84.4% compared with that of n-octadecane. The temperature-regulating fabrics coated with CPCMs have good photothermal conversion properties.

Research limitations/implications

CPCMs with high latent heat properties are applied to the fabric surface through screen printing technology, which not only gives the fabric the photothermal conversion performance but also reflects the design of personalized patterns.

Practical implications

CPCMs and polydimethylsiloxane (PDMS) are mixed to make printing paste and printed cotton fabric with temperature-regulating functional is developed.

Originality/value

SWCNTs and n-octadecane are composited to prepare CPCMs with excellent thermal properties, which can be mixed with PDMS to make printing paste without adding other pastes. The fabric is screen-printed to obtain a personalized pattern and can be given a thermoregulatory function.
