Abstract
Purpose
This study aims to demonstrate whether the educational mismatch prevalent in society can be overcome by various types of lifelong learning and whether lifelong learning can contribute to job satisfaction.
Design/methodology/approach
The participants were 2,559 young Korean employees who graduated from general or specialized vocational high school. This study applied structural equation modeling to verify the mediating effects of lifelong learning on the relationship between educational mismatch and job satisfaction. In addition, this study compared whether the conceptual model results were applied to those who graduated from general school and specialized vocational school through multigroup analysis.
Findings
Regarding the horizontal mismatch, the mediating effect of lifelong learning correlated with job satisfaction was significantly measured in all multigroup models, including the conceptual model. Nevertheless, regarding the vertical mismatch, this study confirmed that informal learning influences job satisfaction differently according to the type of high school from which employees graduated. Furthermore, for those who graduated from specialized vocational school, the relationship between vertical mismatch and job satisfaction was significantly indicated. However, there was no influence of informal learning at the workplace.
Originality/value
This study empirically demonstrated the alternative value of lifelong learning in overcoming the preceding educational mismatch. Moreover, the evidence that such lifelong learning effects may vary depending on the vocational education experiences before entering the labor market is valuable.

Abstract
Purpose
The purpose of this paper is to investigate risk dimensions affecting food risk perceptions and to develop effective risk communication strategies based on their risk perceptions dimensions. The reason for writing this paper is that applying single risk communication strategy for public often fails because food risks are systemic risks and public perceptions toward them consist of multiple dimensions. Launching an effective risk communication need to investigate the perception dimensions of the target audience.
Design/methodology/approach
A total of 2,673 parents of 3-14-year-old children from the rural area of Sichuan province in China were chosen as target audience. Based on the survey conducted about parents’ food risk perceptions, this study used factor-cluster analysis method to segment parents to sub-clusters with significantly different risk perception dimensions. Parents’ representative demographic characteristics within each cluster were further identified through cross-tabs analysis with χ2 tests.
Findings
All the parents could be segmented into four sub-clusters, namely, sensitive parents, dependent parents, familiarity-oriented parents and institutional distrust parents, according to their risk perception difference on five dimensions. A series of risk communication strategies were specifically designed for each cluster based on their risk perception features as well as demographic characteristics.
Originality/value
The insight derived from this study described a deeper image of public risk perceptions and provided suggestions for risk communication launchers to pinpoint the risk perception as well as perception dimensions of the target audience and accordingly develop effective risk communication strategies.

Abstract
Purpose
The purpose of this paper is to research electrochemical testing technology as applied to in field corrosion evaluation of metallic materials and to study the corrosion behaviors of the materials exposed in different marine regions.
Design/methodology/approach
The electrode systems for in field electrochemical evaluation of metallic samples are designed and applied to monitor two types of carbon steel samples exposed both in the submerged zone and the tidal zone at a marine corrosion test station. Corrosion potential monitoring, potentiostatic square wave, electrochemical impedance spectroscopy, and electrochemical noise methods are used in the test.
Findings
It is confirmed that the electrode systems could be used for electrochemical measurement of metallic samples during exposure in the submerged zone and the tidal zone of a marine corrosion test station for long‐term test durations. The electrochemical measuring results reflect the changes and differences of the samples' corrosion behavior during exposure in different regions and they respond directly to the influence of marine environmental factors on the corrosion behaviors, especially the influence of temperature.
Originality/value
In this paper, lots of consecutive and dynamic corrosion information is obtained from field exposures. The findings provide a foundation upon which to investigate and forecast the corrosion behaviors of materials in marine environments.

Abstract
This study examines share price reaction to the enrollment by companies in the Children’s Food and Beverage Advertising Initiative. We find that, on average, in the month of enrollment, shareholders of companies that join the CFBAI experience abnormal return of −3% and so do the shareholders of the immediate competitors that do not join the initiative. However, over the subsequent five years, while the shareholders of companies enrolled in the initiative experience an average abnormal return of +16.6%, that of non-enrolled competitors experience a further abnormal return of −34%. The abnormal returns for the two groups (at the time of enrollment and over the subsequent five years) are uncorrelated and so benefitting at the expense of competitors does not appear to be the motive for enrolling in the CFBAI. The study also provides comparison of number of employees and other important financial ratios before and after enrollment in the CFBAI for the two groups.

Abstract
Purpose
The ballooning health misinformation on social media raises grave concerns. Drawing upon the S-O-R (Stimulus-Organism-Response) model and the information processing literature, this study aims to explore (1) how social media health information seeking (S) affects health misinformation sharing intention (R) through the channel of health misperceptions (O) and (2) whether the mediation process would be contingent upon different information processing predispositions.
Design/methodology/approach
Data were collected from a survey comprising 388 respondents from the Chinese middle-aged or above group, one of China's most susceptible populations to health misinformation. Standard multiple linear regression models and the PROCESS Macro were adopted to examine the direct effect and the moderated mediation model.
Findings
Results bolstered the S-O-R-based mechanism, in which health misperceptions mediated social media health information seeking's effect on health misinformation sharing intention. As an indicator of analytical information processing, need for cognition (NFC) failed to moderate the mediation process. Contrarily, faith in intuition (FI), an indicator reflecting intuitive information processing, served as a significant moderator. The positive association between social media health information seeking and misperceptions was stronger among respondents with low FI.
Originality/value
This study sheds light on health misinformation sharing research by bridging health information seeking, information internalization and information sharing. Moreover, the authors extended the S-O-R model by integrating information processing predispositions, which differs this study from previous literature and advances the extant understanding of how information processing styles work in the face of online health misinformation. The particular age group and the Chinese context further inform context-specific implications regarding online health misinformation regulation.

Abstract
Purpose
The deep integration of emerging technologies such as artificial intelligence (AI) has triggered a transformation in career patterns, requiring employees to promptly adapt to changes in the vocational environment through career crafting. While human resource (HR) practices play a role in guiding employees' career self-management, further exploration is needed to determine the specific HR practices that organizations should adopt to facilitate employees' career crafting. This research takes developmental HR practices as a new premise for career crafting and examines the underlying mechanisms influencing the relationship between the two.
Design/methodology/approach
Using a three-stage time lag method with a two-month lag in each stage, we collected sample data from 386 employees in the intelligent manufacturing industry and employed multiple regression analysis to test the research hypotheses.
Findings
The results of this paper show that developmental HR practices positively influence employees' career crafting behaviors through their future work self and that AI awareness moderates this relationship.
Originality/value
Drawing upon career construction theory, we propose that developmental HR practices cultivate employees' future work self, thereby eliciting career crafting behaviors. Moreover, the mediating role of future work self is more pronounced when employees have a high level of AI awareness, as this awareness stimulates self-cognition-driven behaviors. These findings enrich the understanding of career crafting by shedding light on the career construction process in the relationship between developmental HR practices and career crafting and by identifying the boundary conditions for the relationship.

Abstract
This paper tests two views of bank’s role for Japanese firms. The views are confronted with the empirical evidence, allowing them to compete to explain firm’s cash holding decisions and the implication of cash holdings on firm value. We find that firms with closer bank relations hold less cash, but some of them are over‐borrowing. Our results show that banks do not monitor their client firms and are unlikely to push the managers of the firms to take efficient actions on maximizing firm value. We discover that cash holdings cause more severe agency conflicts for the firms who have the closer relations with the banks.

Abstract
Purpose
This paper aims to study the oxidation kinetics of the nanocrystalline Al ultrathin films. The influence of structure and composition evolution during thermal oxidation will be observed. The reason for the change in the oxidation activation energy on increasing the oxidation temperature will be discussed.
Design/methodology/approach
Al thin films are deposited on the silicon wafers as substrates by vacuumed thermal evaporation under the base pressure of 2 × 10−4 Pa, where the substrates are not heated. A crystalline quartz sensor is used to monitor the film thickness. The film thickness varies in the range from 30 to 100 nm. To keep the silicon substrate from oxidation during thermal oxidation of the Al film, a 50-nm gold film was deposited on the back side of silicon substrate. Isothermal oxidation studies of the Al film were carried out in air to assess the oxidation kinetics at 400-600°C.
Findings
The activation energy is positive and low for the low temperature oxidation, but it becomes apparently negative at higher temperatures. The oxide grains are nano-sized, and γ-Al2O3 crystals are formed at above 500°C. In light of the model by Davies, the grain boundary diffusion is believed to be the reason for the logarithmic oxidation rate rule. The negative activation energy at higher temperatures is apparent, which comes from the decline of diffusion paths due to the formation of the γ-Al2O3 crystals.
Originality/value
It is found that the oxidation kinetics of nanocrystalline Al thin films in air at 400-600°C follows the logarithmic law, and this logarithmic oxidation rate law is related to the grain boundary diffusion. The negative activation energies in the higher temperature range can be attributed to the formation of γ-Al2O3 crystal.
