Desire for experiential travel, avoidance of rituality and social esteem: An empirical study of consumer response to tourism innovation
AbstractThis study investigates tourist consumption responses toward tourism innovation. To measure tourist responses, this study posits three key consumption drivers, namely social esteem, desire for experiential travel, and avoidance against rituality of tourism settings (a subscale of need for uniqueness) and models consumersā affective response within the context of tourism innovation. It involves 295 respondents in an empirical survey. The findings affirm the three drivers toward tourist consumption behavior. Avoidance of rituality reflects tourist preference toward tourism product and service innovation. Desire for experiential travel and the pursuit of social esteem signify tourism management and marketing innovation. Social esteem, need for status and creative choice have significant influence on touristsā affective responses. Acquiring unique tourist products, desire for experiential travel and seeking social esteem are important motivations for tourist consumption. The implications of the study enrich the existing literature of consumer behavior and tourist consumption in response to tourism innovation

Bidirectionally Deformable Motion Modulation For Video-based Human Pose Transfer
Video-based human pose transfer is a video-to-video generation task that
animates a plain source human image based on a series of target human poses.
Considering the difficulties in transferring highly structural patterns on the
garments and discontinuous poses, existing methods often generate
unsatisfactory results such as distorted textures and flickering artifacts. To
address these issues, we propose a novel Deformable Motion Modulation (DMM)
that utilizes geometric kernel offset with adaptive weight modulation to
simultaneously perform feature alignment and style transfer. Different from
normal style modulation used in style transfer, the proposed modulation
mechanism adaptively reconstructs smoothed frames from style codes according to
the object shape through an irregular receptive field of view. To enhance the
spatio-temporal consistency, we leverage bidirectional propagation to extract
the hidden motion information from a warped image sequence generated by noisy
poses. The proposed feature propagation significantly enhances the motion
prediction ability by forward and backward propagation. Both quantitative and
qualitative experimental results demonstrate superiority over the
state-of-the-arts in terms of image fidelity and visual continuity. The source

SVCNet: Scribble-based Video Colorization Network with Temporal Aggregation
In this paper, we propose a scribble-based video colorization network with
temporal aggregation called SVCNet. It can colorize monochrome videos based on
different user-given color scribbles. It addresses three common issues in the
scribble-based video colorization area: colorization vividness, temporal
consistency, and color bleeding. To improve the colorization quality and
strengthen the temporal consistency, we adopt two sequential sub-networks in
SVCNet for precise colorization and temporal smoothing, respectively. The first
stage includes a pyramid feature encoder to incorporate color scribbles with a
grayscale frame, and a semantic feature encoder to extract semantics. The
second stage finetunes the output from the first stage by aggregating the
information of neighboring colorized frames (as short-range connections) and
the first colorized frame (as a long-range connection). To alleviate the color
bleeding artifacts, we learn video colorization and segmentation
simultaneously. Furthermore, we set the majority of operations on a fixed small
image resolution and use a Super-resolution Module at the tail of SVCNet to
recover original sizes. It allows the SVCNet to fit different image resolutions
at the inference. Finally, we evaluate the proposed SVCNet on DAVIS and Videvo
benchmarks. The experimental results demonstrate that SVCNet produces both
higher-quality and more temporally consistent videos than other well-known
video colorization approaches. The codes and models can be found at

VCGAN: Video Colorization with Hybrid Generative Adversarial Network
We propose a hybrid recurrent Video Colorization with Hybrid Generative
Adversarial Network (VCGAN), an improved approach to video colorization using
end-to-end learning. The VCGAN addresses two prevalent issues in the video
colorization domain: Temporal consistency and unification of colorization
network and refinement network into a single architecture. To enhance
colorization quality and spatiotemporal consistency, the mainstream of
generator in VCGAN is assisted by two additional networks, i.e., global feature
extractor and placeholder feature extractor, respectively. The global feature
extractor encodes the global semantics of grayscale input to enhance
colorization quality, whereas the placeholder feature extractor acts as a
feedback connection to encode the semantics of the previous colorized frame in
order to maintain spatiotemporal consistency. If changing the input for
placeholder feature extractor as grayscale input, the hybrid VCGAN also has the
potential to perform image colorization. To improve the consistency of far
frames, we propose a dense long-term loss that smooths the temporal disparity
of every two remote frames. Trained with colorization and temporal losses
jointly, VCGAN strikes a good balance between color vividness and video
continuity. Experimental results demonstrate that VCGAN produces higher-quality
and temporally more consistent colorful videos than existing approaches.Comment: Submitted Major Revision Manuscript of IEEE Transactions on

Bridging dentistry and traditional Chinese medicine : a study on the current mutual understanding among the future practitioners
Objectives: This project aimed to promote the mutual understanding between dental and TCM students. The objectives were to describe the current teaching of dentistry in the TCM schools and that of TCM in the dental school, to describe the TCM studentsā knowledge on dentistry and the dental studentsā knowledge on TCM, and to produce promotional materials for enhancing the mutual understanding between dental and TCM students.
Methods: Information on the current teaching of dentistry in the TCM schools and that of TCM in the dental school was collected through a search on the undergraduate programme syllabus and conducting interviews with the leaders of the schools. Questionnaire surveys were conducted among the final year students of the TCM and the dental schools to collect information on their knowledge of the counter profession. Two leaflets and a short video were produced with the aid of computer software and used in the promotional activities.
Results: It was found that very little information on dentistry was covered in the undergraduate programmes of the three TCM schools, and vice versa in the dental school. A total of 39 TCM students and 55 dental students completed the questionnaire survey. Most of the students did not know the basic theories and practice of the counter profession. Less than half of the student knew what types of patient cases may be suitable for cross-referral to the other profession.
Conclusions: The TCM and dental schools in Hong Kong do not have scheduled teaching on the counter profession. The TCM students have little knowledge on dentistry and how to collaborate with dental practitioners on patients presented with oral problems. Conversely, it is the same for the dental students. Lastly, informative printed and audio-visual promotional materials can be produced with limited resources and used to facilitate the mutual understanding between TCM and dental practitioners.published_or_final_versio
