Abstract

Purpose

This study aims to propose a visualized model of hot technology evolution to describe its development.

Design/methodology/approach

The basic concept is to divide a technological field into a timeline consisting of several patent clusters. Hot technology trajectories are then explored using their continuity, as well as the point in time at which they occur.

Findings

Patents in orthopaedics between 1999 and 2014 have been chosen as the research subjects and the field is divided into several hot technology trajectories. A further step is taken by interpreting high-frequency key terms. Three categories – spine-related materials, bone repairing materials and bone plates – have been identified.

Practical implications

The trajectories presented by evolving diagrams allow readers to understand the evolution of hot technology and help analysts to plan layout and strategies to remain competitive.

Originality/value

Patent clusters reflect the knowledge context of technology development. Previous studies have focused on only new technology evolution and have rarely explored the knowledge context of hot patents that have been frequently cited in recent years. Such patents often guide the development of technology.

Abstract

Purpose

From a functionalist perspective, this study aims to examine empirically how positive and negative emotions can exert influence on creativity in the workplace. This study built and tested a theoretical framework that delineates the effect of emotions on employee creativity through different learning mechanisms.

Design/methodology/approach

Field surveys were conducted in a Chinese company and data were collected from 340 employee-supervisor dyads.

Findings

The results indicate that positive emotions were positively related to task-related learning and interactional learning, both of which promote employee creativity. Task-related learning mediated the association between positive emotions and creativity. Nevertheless, negative emotions hindered employees from interactional learning and were negatively associated with creativity. Interactional learning mediated the association between negative emotions and creativity. Moreover, the interaction between positive and negative emotions was negatively associated with task-related learning.

Originality/value

This study contributes to the literature on emotions and employee learning by demonstrating the value of using a functionalist perspective through different procedural mechanisms for employee outcomes and exploring the mediation effects of different learning behaviors in promoting creativity.

Abstract

Purpose

This paper aims to examine cases of fraudulent financial reporting (FFR) which were subject to published enforcement actions by the Securities Commission Malaysia (SC) from 1998 to 2012 for reasons of alleged financial misreporting. It investigates the main attempts used (how) and sensible motives (why) for these fraudulent reporting.

Design/methodology/approach

This study undertakes a close examination of the financial reports manipulated – annual accounts, interim reports and financial reports in listing proposals, initial public offering prospectuses and corporate restructuring proposals. Due to the limited number of FFR published, a close examination of these cases is the best way to reach a more comprehensive and detailed understanding of “how” FFR takes place, rather than performing large sample statistical analyses. This study also collects data which provide evidence for the possible motivations in resorting to the FFR.

Findings

The most common attempt used by the sample companies was to overstate their reported revenue by recognising fictitious sales from bogus customers. Sample companies who attempted this initial manipulation often followed with consequential manipulations and in some cases also embarked on masking manipulations. Sensible motives for the sample companies to manipulate their financial statements include capital raising exercises, closeness to defaulting on debt repayments and sustaining equity overvaluations.

Research limitations/implications

The primary limitation of this study is its lack of breadth due to the limited number of reported cases available. Moreover, taking the sample companies used from enforcement action releases published by the SC presupposes that the SC has diligently and correctly identified all the FFR cases – whereas there is a possibility that some companies involved in FFR may not yet have been detected or publicly revealed. Notwithstanding these limitations, our findings provide a comprehensive insight, which is sufficient in depth, into the operational aspects of FFR in Malaysia.

Practical implications

One practical lesson from the findings on “how” within the chain of manipulations is that auditors ought to review the effectiveness of their analytical and substantive procedures, as a number of the FFR cases remained undetected by the audit process. A second is that accounting standards setters may wish to reconsider the amount of discretion given to managers in financial reporting. On the one hand, some managers have used this discretion to provide useful information to the market; however, others have opportunistically used it for personal gain.

Social implications

From the societal perspective, it is time for managers, as agents of capital providers, to self-review their responsibilities and stewardship in financial reporting. There needs to be a paradigm shift in their attitudes towards the perceived incentives of, and opportunities for, FFR. Managers’ wrongdoings in these accounting scandals have had significant adverse consequences for society – including minority shareholders, investor confidence, future accountants and managers in the making.

Originality/value

This study provides direct and practical evidence on the “how” and “why” of FFR in the context of a developing country – Malaysia. Such evidence is limited in the existing literature and relevant to practitioners.

Abstract

Purpose

This study aims to propose a research framework grounded in the technology acceptance model (TAM) to assess the new service experiences in the medical industry through examining the intention to use online-to-offline (O2O) medical platforms. It focuses on the connections between immediacy of connection, context-based affordability, reliability and perceived convenience and perceived usefulness. This study also looks at how these determinants affect users’ intentions to use O2O medical platforms, with a particular emphasis on the moderating effect of customer online reviews.

Design/methodology/approach

This study was a quantitative research endeavour grounded in the TAM model that analysed usage intention of O2O medical platforms. Conducted in Sarawak, within the Borneo region, a total of 251 rows of data were collected by questionnaire and underwent initial analysis using SPSS, followed by a more in-depth two-stage partial least squares structural equation model analysis conducted with SmartPLS4.

Findings

According to this study’s findings, perceived usefulness and perceived convenience are significantly impacted by the proposed predictors – immediacy of connection, context-based affordability and reliability. Furthermore, intention to use O2O medical platforms was discovered to have a positive and significant impact from perceived usefulness and perceived convenience. It is noteworthy that the association among perceived convenience and perceived usefulness – which leads to usage intention of O2O medical platforms – did not show the moderating effect of customer online reviews.

Research limitations/implications

The findings suggested that context-based affordability, immediacy of connection and reliability need to be focused on by the information and communication technology developers, policymakers and medical professionals, as these variables can influence perceived convenience and usefulness, which will further impact the intention to use O2O medical platforms.

Originality/value

The formulated research framework holds significance in comprehending the usage intention of O2O medical platforms among consumers in Sarawak. O2O medical platforms have experienced global growth; however, limited studies were found in the Malaysian context. Hence, the objective of this study is to examine the intention to use O2O medical platforms in a relatively understudied area, specifically in Sarawak, an island located in Borneo, Malaysia.

Abstract

Purpose

This study aims to analyze the temperature difference between aluminum-based brake disc (ABD) and cast steel brake disc (CSBD) for rail vehicles in the braking process, which is related to the popularization and use of ABD.

Design/methodology/approach

Two friction pairs composed of ABD, CSBD and copper-based powder metallurgy brake pad were studied in this paper. The temperature characteristics of the two friction pairs were compared by 1:1 braking test and simulation calculation.

Findings

When the speed is 160–250 km/h and the braking pressure is 18 and 29 kN, the calculated maximum temperature of CSBD is 574°C and 681°C, respectively, which is higher than that of ABD 49°C–148°C and 73°C–217°C. Under the test conditions, the maximum temperature of CSBD is 487°C and 624°C respectively, which is higher than that of ABD 63°C–95°C and 63°C–188°C. The temperature difference between ABD and CSBD increases with the increase of braking pressure and speed. The surface temperature distribution of CSBD is “three-peak,” whereas that of ABD is “single-peak.”

Originality/value

This paper reveals the temperature difference between ABD and CSBD and provides data support for promoting the use of ABD.

Abstract

This study proposes a design automation system that integrates traditional segmental design processes into a solid unified system composed of need assessment, computer aided design, computer aided engineering and rapid prototyping. The system utilizes the computer network in conjunction with the quality function deployment technique coupled with a well designed expert system to precisely transform customers’ needs into producible product specification. The product is then displayed using a three‐dimensional representation and simulated through numerical analysis using a finite element method. The resulting feasible design alternative is finally linked to the rapid prototyper to produce the sample object. The use of the system is believed to greatly reduce R&D cost and significantly shorten the product design cycle, while closely meeting the customer’s needs.

Abstract

Purpose

The smart image sensor (SIS) which integrated with both sensor and smart processor has been widely applied in vision-based intelligent perception. In these applications, the linearity of the image sensor is crucial for better processing performance. However, the simple source-follower based readout circuit in the conventional SIS introduces significant nonlinearity. This paper aims to design a low-power in-pixel buffer circuit applied in the high-linearity SIS for the smart perception applications.

Design/methodology/approach

The linearity of the SIS is improved by eliminating the non-ideal effects of transistors and cancelling dynamic threshold voltage that changes with the process variation, voltage and temperature. A low parasitic capacitance low leakage switch is proposed to further improve the linearity of the buffer. Moreover, an area-efficient SIS architecture with a sharing mechanism is presented to further reduce the number of in-pixel transistors.

Findings

A low parasitic capacitance low leakage switch and a gate-source voltage pre-storage method are proposed to further improve the linearity of the buffer. Nonlinear effects introduced by parasitic capacitance switching leakage, etc., have been investigated and solved by proposing low-parasitic and low-leakage switches. The linearity is improved without a power-hungry operational amplifier-based calibration circuit and a noticeable power consumption increment.

Originality/value

The proposed design is implemented using a standard 0.18-µm CMOS process with the active area of 102 µm2. At the power consumption of 5.6 µW, the measured linearity is −63 dB, which is nearly 27 dB better than conventional active pixel sensor (APS) implementation. The proposed low-power buffer circuit increase not only the performance of the SIS but also the lifetime of the smart perception system.

The study investigates the inter-linkages between geopolitical risk (GPR) and food price (FP).

Abstract

Purpose

The study investigates the inter-linkages between geopolitical risk (GPR) and food price (FP).

Design/methodology/approach

By employing the bootstrap full- and sub-sample rolling-window Granger causality tests.

Findings

The empirical results show that there is a time-varying bidirectional causality between GPR and FP. High GPR leads to a rise in FP, suggesting that geopolitical events usually may disrupt supply and demand conditions in food markets, and even trigger global food crises. However, the negative effect of GPR on FP does not support this view in certain periods. This is mainly because GPR is also related to the global economic situation and oil price, which together have impacts on the food market. These results cannot always be supported by the inter-temporal capital asset pricing model, which states that GPR affects FP in a positive manner. Conversely, there is a positive impact of FP on GPR, indicating that the food market is an effective tool that can reflect global geopolitical environment.

Originality/value

In the context of the Russia–Ukraine conflict, these analyses can assist investors and policymakers to understand the sensitivity of FP to GPR. Also, it will provide significant revelations for governments to attach importance to the role of food price information in predicting geopolitical events, thus contributing to a more stable international environment.

The purpose of this paper is to investigate the non-linear threshold effects between trade openness and female labours to participate in the labour markets.

Abstract

Purpose

The purpose of this paper is to investigate the non-linear threshold effects between trade openness and female labours to participate in the labour markets.

Design/methodology/approach

The authors consider data for nine Asian countries from 1990 to 2016 period and perform the panel threshold regression method.

Findings

Empirical results indicate that the threshold value is occurred. With the increase of trade openess, the female labour force participation rate shows a trend of rising first and then declining. Furthermore, exports also have an asymmetric threshold effect on female labour force participation, which is partly in accordance with the discrimination model (Becker, 1957). On the other hand, imports dependency will hinder female labour force participation regardless of a threshold effect. The authors obtain similar results when the authors consider the female employment rate as substitution.

Practical implications

Specifically, increased trade openness may contribute positively or negatively towards overall female labour force participation rate (FLFPR), attributed to the relative importance of these opposing effects. Thus, when the cost reduction effect, resulting from intensified competitive pressure and comparative advantages would enhance the participation rate, the technology channel operates in the opposite direction. Therefore, from the perspective of female employment, trade openness is not the more the better.

Originality/value

This study innovatively discusses the non-linear correlation between trade openness and FLFPR and distinguishes the different contributions from exports and imports. The advanced threshold regression model assumes the existence of threshold value from trade to female employment. Thereby, targeted policies for the government should be applied to promote active female in the labour market.
