Disagreement Resolution in Family Travel Decision-Making—The Role of Adult Children

Adult children traveling with their parents is gaining increasing popularity. As adult children and parents grown up in different social environment, they have formed dissimilar beliefs and core values, which may cause decision-making disagreements when traveling together. However, there has been little research to understand how adult children handle the disagreement with their parents in family trip. Based on this, the current study aims to resolve this question. Moreover, given adult children usually show great filial piety to their parents, and have developed more power in family decision-making. The role of filial piety and decision-making power in adult children’s disagreement management deserve thorough investigations. Specifically, this study examines: (1) How adult children resolve the disagreement in family vacation decision-making; (2) How the filial duty and decision-making power of adult children influences their disagreement resolution. A mixed-methods approach including interviews and scenario-based experiments will be adopted to solve these two problems

The development of foreign publicity translation of marine culture is of great significance to the internationalization of Zhoushan Archipelago New Area. Based on Lasswell 5W mode (Harold Lasswell, 1948), this paper will combine some successful cases of foreign publicity translation of marine culture at home and abroad and analyze the present situation of foreign publicity translation of marine culture in Zhoushan Archipelago New Area by means of questionnaire surveys and the literature study on existing newspapers, periodicals and websites in Zhoushan. Accordingly, some suggestions are put forward to improve the deficiencies of the translation of marine culture in Zhoushan and innovate the ways in translating the marine culture, thus boosting the development of marine tourism economy and promoting the establishment of International Ecological Leisure Tourism Island (2016) in Zhoushan

How does tourism industry dependence affect economic growth in western China? --Based on the inspection and interpretation of the Resource Curse transmission mechanism

The relationship between tourism industry dependence and economic growth is still controversial, and there are few quantitative studies on its transmission mechanism. Based on the Resource Curse hypothesis, the panel data of 46 excellent tourism cities in the western region from 2000 to 2017 was used to examine the existence and transmission mechanism of the Resource Curse. The results show that: tourism industry dependence in the western region of China appears as a curse rather than a gospel for economic growth, and the transmission route of the curse effect is mainly that the tourism industry has a negative impact on the regional economy by squeezing out the manufacturing industry. The findings of the paper provide a theoretical proof for the existence and transmission mechanism of the tourism resource curse in western China, and have certain enlightenment for similar regions to avoid falling into the tourism resources curse trap

Study on the Effect of Cuisine Tourism Resource on Tourists’ Willingness to Visit

This article aims at examining if tourists’ evaluation of cuisine tourism resource has a positive effect on their willingness to visit (WTV) the destination (H1). In Study 1, the content analysis of travelogues of 60 Chinese major tourist cities shows that the scenic spots have a significant effect on WTV, while the effect of cuisine tourism resource on WTV is not supported. Moreover, the tourist city Chengdu with both abundant scenic spots and cuisine resources is chosen for further research of how cuisine resources influence tourist’ decisions. In term of 276 questionnaires (Study 2) and 30 interviewee (Study 3), the results show that the impact of the cuisine resource on WTV is moderated by the tourists’ evaluation on the scenic spots. Only when tourists have a high evaluation on scenic spots, the cuisine resource plays a positive impact on WTV, showing the auxiliary attraction of cuisine resource to tourists

Sampling-based Fast Gradient Rescaling Method for Highly Transferable Adversarial Attacks

Deep neural networks are known to be vulnerable to adversarial examples crafted by adding human-imperceptible perturbations to the benign input. After achieving nearly 100% attack success rates in white-box setting, more focus is shifted to black-box attacks, of which the transferability of adversarial examples has gained significant attention. In either case, the common gradient-based methods generally use the sign function to generate perturbations on the gradient update, that offers a roughly correct direction and has gained great success. But little work pays attention to its possible limitation. In this work, we observe that the deviation between the original gradient and the generated noise may lead to inaccurate gradient update estimation and suboptimal solutions for adversarial transferability. To this end, we propose a Sampling-based Fast Gradient Rescaling Method (S-FGRM). Specifically, we use data rescaling to substitute the sign function without extra computational cost. We further propose a Depth First Sampling method to eliminate the fluctuation of rescaling and stabilize the gradient update. Our method could be used in any gradient-based attacks and is extensible to be integrated with various input transformation or ensemble methods to further improve the adversarial transferability. Extensive experiments on the standard ImageNet dataset show that our method could significantly boost the transferability of gradient-based attacks and outperform the state-of-the-art baselines.Comment: 10 pages, 6 figures, 7 tables. arXiv admin note: substantial text overlap with arXiv:2204.0288

Value Co-Creation and Co-Destruction Through Adult Child–Parent Interactions During Family Vacations: Scale Development and Validation

Although numerous benefits of family vacations have been recognized, the value of family interactions during tourism activities remains under-explored in the literature. Through a series of dual-perspective studies using both qualitative and quantitative approaches, this research developed and validated two multidimensional datasets to measure value co-creation and co-destruction from the perspectives of adult children and their parents on family vacations. The results demonstrate that interactions between adult children and their parents may lead to co-created and co-destructed value, and that children and parents perceive interactive value structures differently. The research also identified two antecedents (family role clarity and prior knowledge) and one consequence (overall experience evaluation) of value co-creation and co-destruction. By developing and validating an effective dual scale for assessing value co-creation and co-destruction through adult child-parent interactions during family vacations, this study advances research on family travel and provides practical evidence that help improve the family travel experience

The current system associated with the boundary of plasma bubbles

The current system associated with the boundary of plasma bubbles in the Earth's magnetotail has been studied by employing Cluster multipoint observations. We have investigated the currents in both the dipolarization front (DF, leading edge of the plasma bubble) and the trailing edge of the plasma bubble. The distribution of currents at the edge indicates that there is a current circuit in the boundary of a plasma bubble. The field‐aligned currents in the trailing edge of the plasma bubble are flowing toward the ionosphere (downward) on the dawnside and away from the ionosphere (upward) on the duskside, in the same sense as region‐1 current. Together with previous studies of the current distributions in the DF and magnetic dip region, we have obtained a more complete picture of the current system surrounding the boundary of plasma bubble. This current system is very similar to the substorm current wedge predicted by MHD simulation models but with much smaller scale.Key PointsWe have obtained a current circuit in the boundary of plasma bubbleThe FACs in the trailing edge of plasma bubble is also region‐1‐senseThe current and FACs system is similar to SCW but with much smaller scalePeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/110641/1/grl52338.pd

Processing and characterization of cobalt silicide nanoparticle-containing silicon carbide fibers through a colloidal method and their underlying mechanism

National Natural Science Foundation of China [51002127, 51072169]Cobalt-containing silicon carbide (Co-SiC) fibers were synthesized through a colloidal method. Dicobalt octacarbonyl [Co-2(CO)(8)] was employed to react with low-molecular weight liquid polycarbosilane (LPCS) to prepare a stable Co-containing colloid (Co-colloid), which was subsequently added to high-molecular weight solid polycarbosilane to obtain the precursor. FTIR, GPC, XRD, and TEM were employed to further understand and develop the mechanism for the formation of the Co-colloid. Results show that active Co intermediates derived from the incomplete decomposition of Co-2(CO)(8) promoted LPCS cross-linkage. The effects of the Co-colloid on the oxidation-curing nature of the green fiber were also investigated. Under heat treatment at higher temperature, carbonyls in the fibers completely decomposed and further crystallized in the morphology of cobalt silicide (CoSi) domains. The effects of Co on the electrical resistivity, magnetic properties, dielectric properties, microwave absorption properties and tensile strength of SiC fibers were also studied

In2S3 Quantum Dots: Preparation, Properties and Optoelectronic Application

Low-dimensional semiconductors exhibit remarkable performances in many device applications because of their unique physical, electrical, and optical properties. In this paper, we report a novel and facile method to synthesize In2S3 quantum dots (QDs) at atmospheric pressure and room temperature conditions. This involves the reaction of sodium sulfide with indium chloride and using sodium dodecyl sulfate (SDS) as a surfactant to produce In2S3 QDs with excellent crystal quality. The properties of the as-prepared In2S3 QDs were investigated and photodetectors based on the QDs were also fabricated to study the use of the material in optoelectronic applications. The results show that the detectivity of the device stabilizes at ~ 1013 Jones at room temperature under 365 nm ultraviolet light irradiation at reverse bias voltage

“Fire-beetles” inspired all-solid infrared sensor with bolometric and photomechanic dual sensing modes

By mimicking the structure of the infrared-sensing organs of the “fire-beetles” of genus Melanophilaacuminata, we herein designed and fabricated an all-soild “fire-beetles” inspired infrared sensor, the key components of which is composed of a stress-concentrated photothermal expansion dendrite structure made of polydopamine enabled polydimethylsiloxane nanocomposite elastomer and a highly-sensitive piezoresistive membrane processed by direct laser writing carbonization. Our sensor possesses bolometric and photomechanic dual sensing modes, with the optimal responsivity of −1.4 W−1 and 2.2 W−1, the detection limit of 0.03 mW/√Hz and 0.23 mW/√Hz, as well as the response time of 3.8 s and 2.5 s, respectively. The two-step photothermal and solid mechanics FEA modeling was performed to help understanding its sensing behavior in both bolometric and photomechanic operation modes, which indicates the possibility for orders-of-magnitude improvement on the responsiveness of our “fire-beetles” inspired IR sensor when increasing the bonding strength between the photothermal dendrite tip and the piezoresistive sensing membrane. The all-solid nature and the piezoresistive read-out scheme as well as its good performance make our sensor valuable for low-cost IR sensing applications
