The purpose of this paper is to evaluate the prediction capability of comprehensive structural dynamics (CSD) analysis codes for the higher harmonic control aeroacoustic rotor test (HART) II data.

A nonlinear flexible multibody dynamics analysis code DYMORE, as well as the comprehensive analytical model of rotorcraft aerodynamics and dynamics (CAMRAD) II, are used to perform the task. The predicted results on rotating free vibration analysis, airloads, blade elastic motions, and structural moments are correlated with the measured data for the baseline, minimum noise, and minimum vibration cases.

The DYMORE analysis results with a free wake model show a good performance in capturing blade vortex interaction peaks in the prediction of section normal forces but apparently with a phase shift problem. The high‐frequency behavior in the airloads signal does not affect much on the aeroelastic response and structural moments of the rotor.

The present approach uses two separate CSD codes to systematically validate the HART II data. The accuracy of each code on structural dynamic aspects of HART II rotor is assessed using a consistent set of inputs. The effects of blade tip deflections on the interaction of blades and their trailed vortices leading to a reduced noise emission are also investigated.

Rambutan (Nephelium lappaceum), a ubiquitous fruit in Southeastern Asia, was rich in vitamins and phytochemicals, which were beneficial for improving of skin conditions. The fermentation process increased phytochemicals and antioxidant capacity. Thus, the purpose of this paper is to examine whether phytochemicals can be increased through the fermentation process of rambutan extracts to improve skin aging.

In this study, the authors used the three stages of fermentation with Saccharomyces cerevisiae, Lactobacillus plantarum TCI028 and Acetobacter aceti under red light to develop a fermented rambutan extract.

The level of polyphenols of red-light-based fermented rambutan extract (RLFRE) were significantly increased 108.9% (p < 0.01) and 97% (p < 0.01) compared with fermented rambutan extract (FRE) and pure rambutan extract (RE), respectively. The human skin fibroblasts treated with 0.03 or 0.06% of RLFRE can significantly decrease reactive oxygen species (ROS) levels by 0.74- (p < 0.001) and 0.84-fold (p < 0.001) compared with H₂O₂ group, respectively. And 0.03% of RLFRE can significantly increase in elastin content by 1.13-fold (p < 0.05). Also, ten compounds were identified including one new phenolic compound and nine known compounds from RLFRE. Moreover, red light could enhance the levels of compounds 4, 9 and 3 by 5, 2.5 and 2.5-fold, respectively, relative to the results of FRE. The last, RLFRE isolated compounds significantly facilitated the elastin content on fibroblast (compound 1, 7, 9, 10 compared with control: p < 0.001, compound 2 compared with control: p < 0.001).

In short, this was the first study to unveil that the red-light-based fermentation can enrich the antioxidant content in a rambutan extract and its product had the potential to be developed a functional product for health-promoting effects such as skin aging.

This study examines the relationship between quality and quantity of open space in residential areas and the sense of community of Chinese older adults in Hong Kong.

A survey was conducted with 257 adults aged 55 and over in Kwun Tong, Hong Kong. The quality of open space was assessed from four dimensions: social and recreational facilities, entrance, location and environment. Geographic information system (GIS) was used to evaluate the quantity of open space in terms of size and amount.

The result shows that the environment has a strong influence on the sense of community, while the quantity of open space does not. The results provide urban planners with evidence for open space planning in the future. Urban planners should consider building more people-oriented environment; such as green areas instead of merely increasing the size, amount and facilities of open space. The Hong Kong Government also needs to review the current standardised planning guideline in order to maximise the social connection of older adults.

This cross-sectional study tried to understand the relationship between the quality and quantity of open spaces and sense of community in Chinese older adults in Hong Kong. It is one of the few studies to simultaneously examine both the quality and quantity of open spaces when studying its relationship with sense of community.

Line–cell conversion and rotation of operators between cells are common in lean production systems. Thus, the purpose of this study is to provide an integrated look at these two practices through integrating job rotation scheduling and line-cell conversion problems, as well as investigating the effect of rotation frequency on flow time of a Seru system.

First, a nonlinear integer programming model of job rotation scheduling problem and line–cell conversion problem (Seru-JRSP) was presented. Then, because Seru-JRSP is NP-hard, an efficient and effective invasive weed optimization (IWO) algorithm was developed. Exploration process of IWO was enhanced by enforcing two shake mechanisms.

Computations of various sample problems showed shorter flow time and less number of assigned operators in a Seru system scheduled through job rotation. Also, nonlinear behavior of flow time versus number of rotation periods was shown. It was demonstrated that, setting number of rotation frequency to one in line with the literature leads to inferior flow time. In addition, ability of developed algorithm to generate clusters of equivalent solutions in terms of flow time was shown.

In this research, integration of job rotation scheduling and line–cell conversion problems was introduced, considering lack of an integrated look at these two practices in the literature. In addition, a new improved IWO equipped with shake enforcement was introduced.

Structural equation modeling was conducted, and a sample with 577 consumers was investigated.

Based on the stimulus–organism–response (SOR) model, this study aims to explore how channel integration affects usage intention through perceived value in food delivery platform (FDP) services. Moreover, the author also examines the moderating effects of personal innovativeness and experience on the relationships in the model.

The study found that channel integration affects usage intention through perceived usefulness, perceived enjoyment and perceived price. Moreover, the moderating effects of personal innovativeness and experience are both significant in the model.

This study found that perceived usefulness, perceived enjoyment and perceived price are three major values influencing the relationship between channel integration and usage intention in FDP services. Moreover, for consumers with high personal innovativeness, perceived usefulness, perceived enjoyment, social image and perceived risk affecting usage intention will be weaker than for consumers with low personal innovativeness. However, for highly experienced consumers, perceived usefulness, perceived enjoyment and perceived price affecting usage intention will be stronger than for less experienced consumers.

This study suggests that practitioners should develop value-driven innovative services and activities by integrating various channels for customers. Moreover, they should segment consumers on the basis of different levels of personal innovativeness and experience to provide different strategies for increasing the intention to use the service.

This study advances the extant knowledge of the SOR model in the context of online-to-offline commerce.

System dynamics is a whole-system modelling and learning approach, useful for tackling non-linear problems, such as sustainable urban development. The purpose of this paper is to review system dynamics applications in the simulation of sustainable urban development over a period from 2005 to 2017.

The analysis reveals that the number of applications of system dynamics modelling in the area of urban sustainable development increased in the analysed period. Research has changed its focus from the modelling of environmental problems to more complex models, portraying the multidimensional socio-economic processes that have an impact on the sustainability of urban development. Analysed case studies most often use the behaviour reproduction test for model validation, but without a unified approach. In most cases, modelling has been done in China, Germany and the USA, while urban development in the Eastern European countries, Africa and Latin America has not often been investigated. This paper indicates the knowledge gaps and suggests future research directions.

Papers that report the use of system dynamics modelling reveal a wide range of applications in urban sustainability. The analysis shows significant emphasis on environmental problems, while the interest for modelling social problems has been increasing during the last several years. Most of the modelled problems examine the sustainability of resources (land, water) and waste management, which are used for insights into the reasons for the system behaviour, forecasting future behaviour and policy testing.

The presented models were developed in most cases for the purpose of understanding the phenomena examined, as well as the future use of the models in policy planning. This brings us back to the need for greater stakeholder involvement, not only in the initial phase, but also during the whole modelling process, which could increase understanding, use and ownership of the models in the future, and thus increase their practical application.

This study investigates the role of source familiarity in moderating the effect of service adaptive behavior (SAB) on customer satisfaction. Applying the accessibility–diagnosticity framework and situated cognition theory as the theoretical basis, this research hypothesizes that when customers are familiar with the source that provides the service (i.e. brand familiarity for Study 1 and personal familiarity for Study 2), customer satisfaction responses to SAB would be more moderate than when customers are not familiar with the source. Two studies were conducted to test the hypotheses.

Two experiments manipulating SAB and the brand name familiarity (Study 1) and personal familiarity with the service staff (Study 2) as the source familiarity were conducted. Customer satisfaction as a function of source familiarity was measured to test the hypothesis that source familiarity moderates the relationship between SAB and customer satisfaction.

Compared to unfamiliar sources, familiar sources generated a more moderate response in customer satisfaction as a function of SAB. High familiarity with the brand and service staff induced top-down, memory-based processing that overrides external stimuli as the basis of satisfaction judgment; bottom-up, stimulus-based processing relying on SAB for judgment kicked in only when the source familiarity is low.

From a practical point of view, this study indicates the importance of SAB, especially for brands with low awareness, and alludes to the comparative importance of relationship building in service delivery processes.

This study contributes to the literature by validating the role of contextual factors in influencing the impact of SAB on customer satisfaction.

This study attempts to fill the research gap by extending sustainability literature and providing empirical evidence that considers sustainability marketing commitment (SMC) as a fundamental attribute of effective marketing strategy that consequently improves tourism service quality, as represented by service attractiveness.

In the current study, data was collected from 313 tourism and hospitality firms. To test the model, this study applied structural equation modeling (SEM) to investigate the relationships among environmental strategy, SMC, supplier trust and service attractiveness in a mediation-moderation setting.

The results indicate that the multiple mediation effects of environmental strategy may indirectly influence tourist attractiveness through SMC and tourism services. The two-way moderating effects reveal that supplier trust and socialization strengthen the service attractiveness development process, while three-way interaction discovered that socialization and supplier trust positively moderate the relationships between tourism services and service attractiveness.

Sustainable strategy is a future trend for tourism business management; however, unknown to most is the role of marketing and environmental strategy in tourism business due to lack of integration with concepts in marketing strategy, with the multidimensionality of tourism services, and with the function of trust and socialization, critically undermining analyses of service attractiveness. This paper combines corporate sustainability and sustainability marketing methods to explore how an environmental strategy can improve tourism services and enhance a destination's attractiveness based on a mediation-moderation mechanism.

A rising trend has been observed to minimize extraneous cognitive load when reading by enhancing secondary knowledge through technology. For the readers to comprehend information more efficiently in their cognitive architecture, instructional procedures, which are secondary knowledge, should be aligned with the modern technology environment. With continual, rapid technological advances in modern society, people have changed their news reading habits after using mobile devices such as smartphones, tablets and e-readers.

This research employed a quantitative survey to compare the changes in the news reading habits of the undergraduate (UG) and postgraduate (PG) students in the Library and Information Management program of a university in Hong Kong after using mobile devices to read electronic news. A total of 102 responses were collected, which comprised 51 UGs and 51 PGs, respectively (the student population for the program was around 100 UGs and 100 PGs).

Survey results showed that mobile devices had changed the respondents’ habit of reading news to read more content on phones, with a variation on news categories. Such changes included the duration and location of news discussion among the respondents that shorter periods were used to read and that more people read while traveling and in restaurants. Notably, reading the news helped respondents in their learning. Most respondents preferred to read electronic news by using mobile devices. The convenience of reading and discussing news may also cause a potential threat that intensifies disputes, arguments or even bullying on controversial issues.

This study confirmed that the usage of the mobile devices changed the respondents’ habit of reading news. This user group constitutes the future generation of information specialists in various disciplines. This study fills the research gap of finding students’ reading habits when using mobile devices, especially in East Asia. Educators are encouraged to recommend relevant news content to students to improve their general knowledge base and arouse their interest in reading and discussing related news topics.
