This paper aims to examine the effects of visual themes and view perspectives on users’ visual attention to brand posts on Instagram. The impact of visual attention on brand attitude and recognition is also explored.

The authors conducted a 4 (visual themes: customer-centric, employee-centric, product-centric and symbolic visuals) × 2 (view perspectives: first-person view vs third-person view) between-subject factorial eye-tracking experiment to explore their effects on viewers’ visual attention (fixation frequency and fixation duration), attitude toward the brand and brand recognition.

Results showed that, under a first-person view, participants spent the longest time viewing customer-centric images and paid the most attention to product-centric and customer-centric images. For images in the third-person view, product-centric images received the longest fixation duration and highest fixation frequency. Customer-centric image and product-centric image generated significantly higher amount of fixation duration and fixation frequency than the symbolic image, regardless of view perspective. Brand recognition was positively influenced by fixation frequency but not by fixation duration.

This study is an extended application of Aaker’s (1996) brand identity planning model in visual branding on Instagram. As the findings indicated, the effective use of visual strategies could lead to more positive responses toward the brand. By understanding how optical elements stimulate visual branding processing, marketing professionals will be able to improve information designing skills in visual-based social media platforms (such as Instagram).

The purpose of this paper is to examine crisis communication strategies used by four leading Chinese milk companies at various crisis stages to cope with the largest food safety crisis in China. Approaching the interplay between the situational crisis communication theory (Coombs, 2007) and the image restoration theory (Benoit, 1995), the study attempted to understand the importance of crisis management at various crisis stages by comparing crisis communication strategies used by surviving and thriving companies with those by the company that failed.

Dividing a crisis management process into three stages, a content analysis was conducted to analyze five major crisis communication strategies – evasion of responsibility, rebuilding, bolstering, endorsement of outside experts and government relations – used by Chinese milk companies at various crisis stages.

The study demonstrated that Sanlu, which went bankrupt as a result of the scandal, predominately took the Chinese crisis management approach. The other three companies that survived the scandal employed western crisis communication strategies, although with distinct Chinese characteristics. Specifically, all four companies employed similar strategies during the pre-crisis stage – keeping silent/covering-up. During the crisis stage, strategies varied dramatically as companies became involved – looking for government protection and apologizing, while survivors tended to adopt a widely used western strategy – bolstering at the post-crisis stage.

The examination of crisis communication strategies at various crisis stages may shed some light on how effectively Chinese companies and possibly international companies in China can manage future crises that share similar profiles as this milk scandal and further call for attention to scrutinize the social responsibility of corporate citizens in China.

This study would fill the vacancy in research by investigating crisis communication strategies used in the largest food safety crisis in China. The findings provide insight for understanding the current status of crisis communication strategies and management within a Chinese matrix of political, social and cultural factors.

The purpose of this paper is to examine empirically how managers establish ethical guanxi (interpersonal relationships) with their business partners to prevent potential ethical incidences in Chinese and Western business contexts.

The present study is guided by a qualitative, abductive approach and draws on in-depth interviews with ten senior managers in five urban New Zealand organisations.

The results point out that guanxi (interpersonal relationships) purely working through renqing (reciprocity) is not sustainable, because it perpetuates a never-ending cycle of favours, once exchanging favours stopped or disappeared, then business relationships dwindled. To establish an ethical guanxi model, the authors found that xinyong (trust) is the foundation, and its enlargement stimulates lijie (empathy) that transfers pure business relationships to a genuine friendship which enhances ethical decision-making. They also posit that once managers are embodied with lijie, then they will have the virtue of ren to behave like junzi (ideal Confucian ethical person) whose business actions tend to be intrinsically guided by a sense of obligation to do something right that will work for diverse stakeholders’ interests, for the prosperity of organisations and society.

This study suggests that managers should take Confucian virtues of xinyong (trust) and lijie (empathy), because they will trigger ren (humanity) as an intrinsic value. In this way, it is more likely for them to become junzi (ideal Confucian ethical person) whose business actions are intrinsically guided by a sense of obligation to do something right that benefits various stakeholders, organisations and society.

This study contributes to the extant literature on preventing ethical incidents of guanxi (interpersonal relationships) by drawing a framework of ethical guanxi, which is built on Confucian virtues of xinyong (trust), lijie (empathy) and ren (humanity). Further, this paper strongly suggests that companies should educate their staff to become more humane to make moral decisions in daily management practice.

In parallel sampling method, the size of the sampling capacitor is reduced to improve the bandwidth of the ADC.

Various low-power techniques for 10-bit 200MS/s pipelined analog-to-digital converter (ADC) are presented. This work comprises two techniques including parallel sampling and switched op-amp sharing technique.

This paper aims to study the effect of parallel sampling and switched op-amp sharing techniques on power consumption in pipelined ADC. In switched op-amp sharing technique, the numbers of op-amps used in the stages are reduced. Because of the reduction in the size of capacitors in parallel sampling technique and op-amps in the switched op-amp sharing technique, the power consumption of the proposed pipelined ADC is reduced to a greater extent.

Simulated the 10-bit 200MS/s pipelined ADC with complementary metal oxide semiconductor process and the simulation results shows a maximum differential non-linearity of +0.31/−0.31 LSB and the maximum integral non-linearity (of +0.74/−0.74 LSB with 62.9 dB SFDR, 55.90 dB SNDR and ENOB of 8.99 bits, respectively, for 18mW power consumption with the supply voltage of 1.8 V.

Implementing servitization requires collaborative efforts from multiple actors in the business network or ecosystem. A multi-actor perspective is considered valuable for understanding the process of servitization. This study aims to review the contemporary research on organizing servitization by multi-actor collaborations.

The approach of systematic literature review was used. In total, 90 English-language journal articles published from 2004 to 2021 were selected based on a series of rigorous steps. Furthermore, descriptive and thematic analyses were conducted to answer the predefined review questions.

The servitization research from the multi-actor collaboration perspective is an infant field yet growing increasingly. An integrative framework was proposed to reveal the extant related studies. In this framework, three typical servitization lenses emphasizing multi-actor collaborations were uncovered. Moreover, six categories of influence factors and possible positive and negative outcomes for this process were identified. Existing knowledge gaps and underlying research directions were also discussed to lay the foundations for future research.

This research has been limited by the usage of single database, rigorous selection criteria by the Academic Journal Guide (AJG 2018) list and exclusion of non-English papers.

To the best of the authors’ knowledge, this study is one of the earliest systematic literature reviews to explore the servitization issues by adopting a multi-actor perspective. The findings can consolidate the knowledge base of servitization and provide implications for the multiple fields of industrial marketing, operational management, information management and service marketing.

This study presented the experience of improving the nucleic acid sample collection and transportation service in response to the epidemic. The main purpose is that through intelligent path planning, combined with the time scheduling of sample points, the process of obtaining results to determine the state of COVID-19 patients could be speeding up.

The research optimized the process, including finding an optimal path to traverse all sample points in the hospital area via intelligent path planning method and standardizing the operation through the time sequence scheduling of each round of support staff to collect and send samples in the hospital area, so as to ensure the shortest time in each round. And the study examines these real-time experiments through retrospective examination.

The real-time experiments' data showed that the proposed path planning and scheduling model could provide a reliable reference for improving the efficiency of hospital logistics. Testing is a very important part of diagnosis and prompt results are essential. It shows the possibility of applying the shortest-path algorithms to optimize sample collection processes in the hospital and presents the case study that gives the expected outcomes of such a process.

The value of the study lies in the abstraction of a very practical and urgent problem into a TSP. Combining the ant colony algorithm with the genetic algorithm (ACAGA), the performance of path planning is improved. Under the intervention and guidance, the efficiency of hospital regional logistics planning was greatly improved, which may be of greater benefit to critical patients who must go through fever clinic during the epidemic. By detailing how to more rapidly obtain results through engineering method, the paper contributes ideas and plans for practitioners to use. The experience and lessons learned from Tongji Hospital are expected to provide guidance for supporting service measures in national public health infrastructure management and valuable reference for the development of hospitals in other countries or regions.

The purpose of this paper is to analyze the cavitation characteristics of a water hydraulic axial piston motor (WHAPM) to improve the water motor performance, to reduce the vibration and noise and to prolong the service life of the motor.

The computational fluid dynamics (CFD) software PumpLinx is chosen to do cavitation analysis of the WHAPM. In this case, first, cavitation mechanism of the water piston motor is analyzed in depth. Then, considering the effects of bubble dynamics, the rate of phase transition, turbulence effects and non-condensable gas, the full cavitation model is selected, the dynamic CFD numerical model of internal flow field on the water hydraulic piston motor is established based on PumpLinx software and the fluid cavitation inside is numerically studied. Finally, the influence of the valve plate and pistons on motor cavitation is analyzed.

Research results show that there are two serious cavitation regions: one is the pressure transition region of the valve plate that is near the top dead center, and the other is the low-pressure region of the piston that is near the low-pressure transition area. Moreover, the more serious cavitation area is on the valve plate region.

The simulation results show that the proposed algorithm is able to detect the cavitation characteristics of the water piston motor. Besides, it is deduced that valve-plate structure optimization is more important than pistons to reduce cavitation influence.

This paper aims to clarify the fluid infiltration mechanism at the micro-contact zone boundary of rubber-glass interfaces.

An in situ observation instrument was putted up; then the fluid infiltration process was recorded. Experimental results indicated that the fluid infiltration was more likely to occur in a high-contact-area-ratio zone, and the path order of fluid infiltration was first inner normal to the boundary of micro-contact area, and then along the boundary, at last external normal to the direction of boundary.

By analysis, capillary pressure is the driven force of fluid at interfaces. The micro-channel size at higher-contact-area-ratio zone is smaller, and the capillary pressure is bigger. Moreover, along different section directions of wedge-shaped region, the horizontal driving force of fluid is different due to difference of conical angle.

The main contribution of this study is proposing a new wedge-shaped model for better understanding the phenomena of fluid infiltration at rubber contact interfaces.

In this paper, the authors aim to study the effect of hydrogen on the pitting corrosion behavior of Incoloy 825, a commonly used material for heat exchanger tubes in hydrogenated heat exchangers.

The pitting initiation and propagation behaviors were investigated by electrochemical and chemical immersion experiments and observed and analyzed by scanning electron microscope and energy dispersive spectrometer methods.

The results show that hydrogen significantly affects the electrochemical behavior of Incoloy 825; the self-corrosion potential decreased from −197 mV before hydrogen charging to −263 mV, −270 mV and −657 mV after hydrogen charging, and the corrosion current density increased from 0.049 µA/cm² before hydrogen charging to 2.490 µA/cm², 2.560 µA/cm² and 2.780 µA/cm² after hydrogen charging. The pitting susceptibility of the material increases.

Hydrogen is enriched on the precipitate, and the pitting corrosion also initiates at that location. The synergistic effect of hydrogen and precipitate destroys the passive film on the metal surface and promotes pitting initiation.

This paper aims to optimize the weighing control system and compensate weighing error for weighing control system of coal mine paste-filling weighing control system.

The process of the paste-filling weighing control system is analyzed and the mathematical model of the paste-filling material weight is established. Then, the back-propagation (BP) neural network is used to optimize the control system and compensate the weighing error.

Without the BP neural network, the weighing error of the paste-filling control system is more than 3 per cent, whereas after optimization with the BP neural network, the weighing error is less than 1 per cent. With the simulation results, it is seen that the weighing error of the paste-filling control system decreases and the accuracy of the weighing control system improves and optimizes.

The method can be further used to improve the control precision of the coal mine paste-filling system.
