    Homeless food delivery riders and their transportal home in Shanghai's lockdown
    SAGE Publications ; 2023
    In:  Mobile Media & Communication
    Details
    In: Mobile Media & Communication, SAGE Publications
    Abstract: This article draws on the concept of “transportal home” to examine the intersection of mobile media, mobility, and place-making among homeless food delivery workers in the Shanghai lockdown. Shanghai's lockdown lasted from February 28 to May 31, 2022, and was one of the strictest in China, resulting in thousands of food delivery riders being locked out of their homes, treated as potential carriers of the virus, and forced to sleep on the streets until the lockdown was lifted. The article uses qualitative research methods to explore the COVID-related homelessness of food delivery riders during the lockdown, focusing on their media practices and highlighting their experiences and agency in using mobile media to negotiate their lives amid the (im)mobile mobility they faced. It argues that mobile phones, as a transportal home, can offer a technological imaginary of home out of “homelessness”; however, they also serve as a reminder of the constraints of such an imaginary, as these (temporarily) homeless food delivery riders continue to be subject to platform exploitation and pandemic surveillance.

    LAPM: The Location Aware Prediction Model in Human Sensing Systems

    Abstract: The mobile human social network actually might be the hugest and best “sensor network” because of the explosive growth in social network content. Nowadays, more and more mobile social applications offer a much easier way for people to share their feeling including vision, haptic, hearing, and smell with the location information by words, images, or even videos. These new sharing methods appearing in the mobile social network actually give us a precious chance to sense the world. Extra systems, which are specialized in particular sensing, do not need to be created any more. The specific sensing data can be acquired from the social network by handling the heterogeneous data. The contribution of this paper lies in developing a model that collects samples considering the relevancy from the perspective of location from different mobile social networks and estimating the occurrence likelihood of the perceived event with collected samples. The simulations and real-world case studies are also developed to verify the reliability of the model and the effectiveness of the Location Aware EM algorithm.

    Cost-effectiveness of enfortumab vedotin in previously treated advanced urothelial carcinoma
    SAGE Publications ; 2022

    Abstract: Antibody-drug conjugates have recently been introduced as a treatment for advanced urothelial carcinoma. The EV-301 study demonstrated that enfortumab vedotin (EV) improved overall survival compared with conventional chemotherapy. To assess the cost-effectiveness of EV for the treatment of advanced urothelial carcinoma (UC) from a payer perspective in middle- and high-income countries. Methods: A decision analysis model was developed to assess the efficacy and economic viability of EV as a subsequent-line treatment following disease progression in patients with advanced urothelial carcinoma already treated with PD-1 or PD-L1 inhibitors. Clinical and utility values were obtained from the published literature and available databases. Cost data were obtained from payer perspectives in the United States, United Kingdom, and China. Quality-adjusted life-years (QALYs) were used to measure health outcomes, and incremental cost-effectiveness ratios (ICERs) used to evaluate cost-effectiveness in comparison to willingness-to-pay in the United States, United Kingdom, and China. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to assess the robustness of the model. Results: Compared with chemotherapy, EV increased the benefit by 0.16-0.17 QALYs, resulting in ICERs of $2,168,746.71, $2,164,494.38, and $1,775,576.56 per QALY in the United States, United Kingdom, and China, respectively. One-way sensitivity analysis indicated that the largest effect on outcome was the utility value for progression-free survival. Probabilistic sensitivity analysis demonstrated that the probability of EV being cost-effective was 0%. Conclusions: EV provides an additional health benefit over chemotherapy for patients with advanced urothelial carcinoma but is not cost-effective from a payer perspective in the United States, United Kingdom, or China.

    GPU-assisted energy asynchronous diffusion parallel computing model for soft tissue deformation simulation

    Abstract: Soft tissue deformation simulation is a key technology of virtual surgical simulation. In this work, we present a graphics processing unit (GPU)-assisted energy asynchronous diffusion parallel computing model which is stable and fast in processing complex models, especially concave surface models. We adopt hexahedral voxels to represent the physical model of soft tissue to improve the visual realistic quality and computing efficiency of deformation simulation. We also adopt the concept of free boundary to simulate soft tissue geometric characteristics more precisely during the deformation process and introduce asynchronous diffusion by using the mechanical energy of mass points to achieve realistic soft tissue deformation effects. In order to meet the requirement of real-time surgery simulation, we accelerate the soft tissue deformation by using OpenCL (Open Computing Language) and optimize the parallel computing process in several means. Experimental results have shown that the GPU-assisted energy asynchronous diffusion parallel computing model for soft tissue deformation simulation implements satisfactory effects on deformation in visual realistic and real-time quality.

    Love your idol in a ‘cleaned’ way: Fans, fundraising platform, and fandom governance in China

    Abstract: In 2021, a top-down rectification movement called ‘Clean Up’ impinged on Chinese idol fandom culture. This movement triggered discussions about the transforming governance strategy over fandom and broader Chinese Internet users. This article explores the complexity and shift of governance on Chinese idol fans by examining the digital fandom fundraising platform Taoba. Drawing from the walkthrough analysis of xiufen (fans of idol competition shows), we investigate three key stakeholders: platform, state, and xiufen fandom, to reflect on wider Internet governance issues in China. We argue that Chinese idol fans like xiufen are subject to a governance structure where power relations between different players are highly complex and entangled. The state-corporate-society co-opting mode of governance has evolved toward what we termed ‘coercive co-opting’, in which digital platforms and users conform with the imaginaries and ideologies of the state, while the authorities still intervene in an intimidating and suppressive manner.
