Corporate Social Responsibility (CSR) activities substantially impact a company’s reputation. As companies increasingly embrace social media to communicate CSR activities, they face the challenge of selecting the appropriate message source. In this context, this paper examines the role of message source in the relationship between CSR communication and corporate reputation.

The impact of firms' marketing communication on word of mouth (WOM) has been studied extensively in recent years, with a growing focus on electronic word of mouth (eWOM). The advent of the internet and the participatory web or Web 2.0 has dramatically changed the relationship between marketers and consumers, with consumers playing a more active role. However, there is a gap in understanding this area, including a lack of research on identifying specific groups of consumers that companies should focus on for eWOM marketing. Eye-tracking techniques have been suggested to address this issue, but these methods can be costly and rely on lab-based observations. Analyzing unstructured data from consumer-to-consumer interactions on social media is an underutilized approach in current marketing literature. The authenticity of eWOM is a highly valuable trait, but there can be a tension between commercial and communal norms, even in relatively informal settings like a blogger endorsing a product.

The use of artificial intelligence (AI) service robots is on the rise. With service frontlines gradually shifting to human–robot interactions, the question of whether AI robots should be humanlike or machinelike has emerged. While many firms use robots that resemble humans in their appearance and actions, others use machinelike robots, assuming that very humanlike robots may lead to uncanny valley effects. There is no consensus on whether the anthropomorphism of service robots facilitates or constrains consumers’ experiences. To fill this gap, this article examines when and how service companies should use anthropomorphic AI service robots.

Metaverse tourism is blurring the boundaries between the virtual and physical worlds. Among the core technologies in the metaverse world (e.g., Avatar, Virtual reality, Augmented reality, NFTs, etc.), the avatar has the potential power to revolutionise customer experience. Destination management organisation (DMO) can boost customers’ immersion through effective avatar customer journey design (ACJD) in the metaverse world. Yet, there is a lack understanding of how practitioners view an effective ACJD in the metaverse world. This study aims to explore the role of avatars on customer journey design in a metaverse tourism program (e.g., Dunhuang) from practitioners’ perspectives through a qualitative study. This study advances theoretical understanding about metaverse tourism in the tourism literature, and provides important implications for tourism industry on how to design tourist experiences in metaverse tourism.

The unbounded nature of digital innovation requires innovating firms to be agile in the way they manage the processes, governance and outcomes in order to sense and seize the market directly and timely. This study adopts an inter-organizational approach and asks to what extent and in what way does organizational agility impact on innovation performance? This perspective underscores the interdependencies between collaborating partners, which creates a relationship regulating system of workflow to drive value creation in the process of innovation. While the literature has offered a broad conceptual argument for organizational agility in the context of digital innovation, the mechanisms through which value is transformed in the innovation process is still unclear. We contend that an agile innovation process stands on four main cornerstones: (1) joint strategic planning, (2) joint problem solving, (3) joint improvisation and (4) community (market) sensing. The empirical research is set in the video game industry, which is in a largely digitalized and borderless business environment. The data was collected through an interviewer-administered questionnaire. The sampling frame is based on a Swedish trade association database. Usable sample is 113. We performed structural equation modelling to test the hypothesized model, including main and moderation effects, using Mplus. The findings show that while only improvisation has a significantly positive effect on innovation performance, the role of strategic planning and problem solving between two collaborating partners remains unclear. For example, strategic planning has shown to be a negative influence in our empirical research. Problem solving has no effect on innovation performance, but it interacts with community sensing and subsequently facilitates innovation outcome. This highlights the importance of community sensing, which could offer rich, crucial knowledge and resources for problem solving that proves to be effective. The results provide further theoretical arguments for understanding organizational agility and digital innovation, but also raise further questions for future research.

This research presents a conceptual framework for a comprehensive understanding of the causes of user migration from social media networking sites. The results of our survey show that users’ intentions to switch social media platforms are influenced by user satisfaction, alternative attractiveness, peer influence, and perceived switching costs.

The hospitality industry is widely using customer data to develop successful personalized marketing communication. However, in the event of information leakage, personalized advertising may escalate customers’ privacy distress. Building on Conservation of Resources theory, this study proposes three dimensions for privacy threats that impact the relationship between personalized hospitality advertising and consumer responses. Findings from six experiments across high and low involvement hospitality products demonstrate diverging effects of personalized advertising depending on the type of privacy threat communicated. Results further indicate that customers’ psychological comfort mediates the relationship between high-personalized advertising and the customer response to the advertising when privacy threat is high. Additionally, when the perceived severity and distance of the announced privacy threat are high and low respectively, rational appeals generate higher levels of psychological comfort, while the same happens for emotional appeals when the perceived scope of the threat is high. The study concludes with value-adding theoretical and managerial implications for the hospitality industry.

The economic recession and changes in purchasing habits of young adults (aged 18–25) has led to a decline in the sales of Japanese fashion apparel. This younger generation’s choice of fashion items is primarily based on price. They are not devoted to a favourite brand with a frequent purchase history. Thus, developing customer loyalty and strengthening brand value are essential for the fashion industry. This study explores the improvement in fashion companies’ financial performance (FP) through young generation’s behavioural brand loyalty (BBL) from two aspects: social media brand engagement (BE) and loyalty programmes (LPs). This study listed 14 popular Japanese fashion brands which belonged to 14 publicly traded companies in Japan. Further, we surveyed 183 consumers about their brand related behaviours. The findings reveal the positive and negative effects of the same variable (BE and LPs) on the outcome (short- and long-term FP), indicating that not all activities related to BE and LPs boost FP. FP is influenced by various combinations of these causal factors and complex situations, such as consumers’ demographics and shopping characteristics. The results deepen our understanding of brand loyalty formation and the linkage among BE, LPs, and FP in a realistic marketplace, and offer multiple practical solutions to achieve high levels of short- and long-term FP by targeting the right consumers based on their specific characteristics.

The Wide-Angle Polarimetric Camera (PolCam) is installed on the Korea’s lunar orbiter, Danuri, which launched on August 5, 2022. The mission objectives of PolCam are to construct photometric maps at a wavelength of 336 nm and polarization maps at 461 and 748 nm, with a phase angle range of 0◦–135◦ and a spatial resolution of less than 100 m. PolCam is an imager using the push-broom method and has two cameras, Cam 1 and Cam 2, with a viewing angle of 45◦ to the right and left of the spacecraft’s direction of orbit. We conducted performance tests in a laboratory setting before installing PolCam’s flight model on the spacecraft. We analyzed the CCD’s dark current, flat-field frame, spot size, and light flux. The dark current was obtained during thermal / vacuum test with various temperatures and the flat-field frame data was also obtained with an integrating sphere and tungsten light bulb. We describe the calibration method and results in this study.

Background: As sedentary life increases, people's thoracic vertebra joint movement decreases, and the resulting associated pain is complaining of a lot of discomfort. This is also affecting the autonomic nervous system. Objectives: The purpose of this study was therefore to find out the effect of thoracic vertebra joint mobilization on heart rate variability in upper back pain patients. Design: Randomized controlled trial. Method: Thirty subjects in this study were randomly assigned to two groups of 15 persons each using a randomization tool. Maitland's grade III joint mobilization, hot pack, and interferential current therapy (ICT) were applied to T1-L2 and hot pack and ICT were applied to the control group. The intervention was performed 3 times a week for 4 weeks. Results: There were statistically significant changes in Visual Analog Scale (VAS), Standard Deviation of all Normal R-R Intervals (SDNN), Low Frequency (LF), High Frequency (HF) and LF/HF ratio in the study group, and statistically significant changes in VAS, SDNN, and LF/HF ratio in the control group. In comparison of differences, there were statistically significant changes in VAS. Conclusion: Positive effects were found on SDNN and LF/HF ratio in both the joint mobilization group and the control group compared to before the study. In particular, even LF and HF were positive in the joint mobilization group showed influence.

Carbon-based materials have emerged as an excellent class of biomedical materials due to their exceptional mechanical properties, lower surface friction, and resistance to wear, tear, and corrosion. Experimental studies have shown the promising results of carbon-based coatings in the field of biomedical implants. The reasons for their successful applications are their ability to suppress thrombo-inflammatory reactions which are evoked as an immune response due to foreign body object implantation. Different types of carbon coatings such as diamond-like carbon, pyrolytic carbon, silicon carbide, and graphene have been extensively studied and utilized in various fields of life including the biomedical industry. Their atomic arrangement and structural properties give rise to unique features which make them suitable for multiple applications. Due to the specificity and hardness of carbon-based precursors, only a specific type of coating technique may be utilized for nanostructure development and fabrication. In this paper, different coating techniques are discussed which were selected based on the substrate material, the type of implant, and the thickness of coating layer. Chemical vapor deposition-based techniques, thermal spray coating, pulsed laser deposition, and biomimetic coatings are some of the most common techniques that are used in the field of biomaterials to deposit a coating layer on the implant. Literature gathered in this review has significance in the field of biomedical implant industry to reduce its failure rate by making surfaces inert, decreasing corrosion related issues and enhancing biocompatibility.

This study investigated durian (Durio zibethinus) peels to produce powdered activated carbon (DPAC). The influence of process variables such as carbonization temperature, activation time, contact time, CO2 flow rate, and adsorption dosage was optimized using response surface methodology (RSM). A six-factor and two levels Box–Behnken design (BBD) was used to optimize the parameters. The independent variables were activation temperature (°C), duration (min), CO2 flow rate during the activation process (L/min), irradiation of adsorbent (kGy), irradiation duration (min), and adsorbent dosage (g) while phenol removal (mg/L) was the dependent variable (response). Following the observed correlation coefficient values, the design was fitted to a quadratic model (R2 = 0.9896). The optimal removal efficiency (97.25%) was observed at an activation temperature of 900 °C, activation time of 30 min, CO2 flow rate of 0.05 L/min, irradiation dose of 100 kGy, contact time of 35 min and adsorption dosage of 0.75 g. The optimal DPAC showed a BET surface of 281.33 m2/ g. The removal efficiency was later compared with a commercially available activated carbon which shows a 98.56% phenol removal. The results show that the durian peel could be an effective precursor for making activated carbon for phenol removal, and irradiation can significantly enhance surface activation.

An all-perovskite oxide heterostructure composed of SrSnO3/Nb-doped SrTiO3 was fabricated using the pulsed laser deposition method. In-plane and out-of-plane structural characterization of the fabricated films were analyzed by x-ray diffraction with θ-2θ scans and φ scans. X-ray photoelectron spectroscopy measurement was performed to check the film’s composition. The electrical transport characteristic of the heterostructure was determined by applying a pulsed dc bias across the interface. Unusual transport properties of the interface between the SrSnO3 and Nb-doped SrTiO3 were investigated at temperatures from 100 to 300 K. A diodelike rectifying behavior was observed in the temperature-dependent current-voltage (IV) measurements. The forward current showed the typical IV characteristics of p-n junctions or Schottky diodes, and were perfectly fitted using the thermionic emission model. Two regions with different transport mechanism were detected, and the boundary curve was expressed by ln I = -1.28V - 13. Under reverse bias, however, the temperature- dependent IV curves revealed an unusual increase in the reverse-bias current with decreasing temperature, indicating tunneling effects at the interface. The Poole-Frenkel emission was used to explain this electrical transport mechanism under the reverse voltages.

The objective of the present experiment was to investigate the effects of dietary vitamin C (VC), vitamin E (VE), and betaine (BT) supplementations on productive performance, egg quality, relative organ weights, liver visual characteristics, antioxidant status, immune response, and stress indicator in laying hens raised under heat stress conditions. A total of 280 47-wk-old Hy-Line Brown laying hens were allotted to 1 of 4 dietary treatments with 7 replicates in a completely randomized design. Each replicate had 10 birds per cage. The basal diet was formulated to meet or exceed the requirement estimates for Hy-Line Brown laying hens. Three additional diets were prepared by adding 250 mg/kg VC, 250 mg/kg VE, or 3,000 mg/kg BT to the basal diet. The experimental diets and water were provided to hens on an ad libitum basis for 8 wk. Average daily room temperature and relative humidity were 30.7±1.41℃ and 72.5±11.61%, respectively. Results indicated that hens fed diets containing 250 mg/kg VE had a less (p<0.05) egg production rate than other dietary treatments. For egg quality, hens fed diets containing 3,000 mg/kg BT had a less (p<0.05) eggshell thickness than those fed the diets containing 250 mg/kg VC or 250 mg/kg VE. For antioxidant status, there was a tendency (p=0.09) for the least malondialdehyde (MDA) concentrations in the liver for BT treatment. A tendency (p=0.05) was observed for less blood heterophil:lymphocyte ratio in BT treatment as compared to other treatments. In conclusion, dietary supplementation of 250 mg/kg VC, 250 mg/kg VE, and 3,000 mg/kg BT has no beneficial effects on productive performance, egg quality, relative organ weights, liver visual characteristics, and immune responses of laying hens raised under the current heat stress conditions. However, dietary supplementation of 3,000 mg/kg BT alleviates antioxidant status and stress response of laying hens exposed to heat stress.

Background: Germ cells undergo towards male or female pathways to produce spermatozoa or oocyte respectively which is essential for sexual reproduction. Mesenchymal stem cells (MSCs) have the potential of trans-differentiation to the multiple cell lineages. Methods: Herein, rat MSCs were isolated from bone marrow and characterized by their morphological features, expression of MSC surface markers, and in vitro differentiation capability. Results: Thereafter, we induced these cells only by retinoic acid supplementation in MSC medium and, could able to show that bone marrow derived MSCs are capable to trans-differentiate into male germ cell-like cells in vitro. We characterized these cells by morphological changes, the expressions of germ cell specific markers by immunophenotyping and molecular biology tools. Further, we quantified these differentiated cells. Conclusions: This study suggests that only Retinoic acid in culture medium could induce bone marrow MSCs to differentiate germ cell-like cells in vitro . This basic method of germ cell generation might be helpful in the prospective applications of this technology.

This paper probes the elements of theoretical necessity, starting with the word ruo (若) in Duan Yucai’s Shuo Wen Jie Zi Zhu (段玉裁《說文解字註》). From the prospective of theoretical methods of “Ruo (若) ,” the theoretical necessity of “Ruo (若) ,” the exegesis functions of “Ruo (若) ” and different intonations with different modal particles, the author conducted multi-level and multi-dimensional analysis on “Ruo (若) ” in Duan Yucai’s Shuo Wen Jie Zi Zhu (段玉裁《說文解 字註》) so as to explore the concepts of theoretical necessity from Duan Yucai.

Toll-like receptor 4 (TLR4) is known to contribute to the modulation of insulin resistance and systemic inflammation seen in obesity and the metabolic syndrome. The present study was performed to investigate the fertility competence of TLR4 knock out male mice (TLR4 mice) on a high-fat diet (HFD), compared to a normal-chow diet (NCD). The controls included wildtype (WT) mice fed on a HFD or NCD. Six-week-old male mice were fed with either a NCD or HFD for 20 weeks. Body and organ weights, serum levels of glucose, triglycerides and hepatoxicity, sperm quality and spermatogenesis were observed after the sacrifice. Also, randomly selected male mice were mated with virgin female mice after feeding of 19 weeks. The weight of the body and organs increased in WT and TLR4 mice on a HFD compared to those of mice on a NCD. The weights of the reproductive organs did not vary among the treatment groups. The motility and concentration of the epididymal spermatozoa decreased in both WT and TLR4 mice fed a HFD. The pregnancy rate and litter size declined in the HFD-fed WT mice compared to the HFD-fed TLR4 mice. In conclusion, the HFD alters energy and steroid metabolism in mice, which may lead to male reproductive disorders. However, fertility competence was somewhat restored in HFD-fed TLR4 male mice, suggesting that the TLR4 is involved in testis dysfunction due to metabolic imbalance.

At present, the assessment for the crew training using the ship handling simulator is completed by the assessor, which is subjective and difficult to unify the assessment criteria. Under this assessment mode, the assessor will have a great work intensity. So it is necessary to design and develop the automatic assessment system for the ship handling simulator. This paper introduces the automatic assessment system developed by Dalian Maritime University (shorted for DMU), which includes the assessment method, system architecture and implementation. A selected example of applications is described.

This study aims to establish a development strategy for higher education in Indonesia’s marine and fisheries sector and to present a direction for international development cooperation through evaluating policies and current problems related to higher education in marine and fisheries sector. To achieve the goals of human resources development in marine and fisheries sector, Indonesian government needs to secure non-salary expenditures to strengthen support for areas directly related to the effects of education, such as improving educational facilities, expanding scholarships, and so on. Education institution needs to develop effective teaching methods and systematic practice-based curriculum that reflects the needs of the local fishermen community and fisheries industry. In addition, it is necessary to support the supply of manpower throughout the fisheries industry. Fisheries industry needs to stop relying on the government or education institutions to secure excellent human resources and actively participate and cooperate in the education field so that excellent human resources can flow into the industry. Based on this strategy, international development cooperation for human resources development in Indonesia’s marine and fisheries sector should focus on qualitative rather than quantitative expansion of higher education institutions.
