The Ambivalent Vision: The "Crip" Invention of "Blind Vision" in Blind Massage

Blind Massage, a film directed by Lou Ye (2014), depicts disability and sexuality through stories of blind masseurs. It employs “blind vision”, a novel form of cinematography that depicts blindness, assisting the film in unfolding the subjective experience of the blind masseurs in both sexual and non-sexual scenes. With the invention of blind vision, Blind Massage introduced a non-normative cinematic experience that decentres vision, while cinema had previously been perceived as an intrinsically visual-centred art form. This paper, therefore, asks: How does the am­bivalent representation of vision contribute to the cinematic representation of disabled sexuality? Does it reinvent or reinforce the normative understanding of disabled sexuality? As a response, the paper argues that the invention of blind vision destabilises the ableist foundation of cinema that centres on visual experience as the source of pleasure. It mainly grounds the argumentation on criticism of Mulvey’s (1975) gaze theory, which discusses visual pleasure and narrative cinema with the psychoanalytic gaze notion. The notion of blind vision will be elab­orated on, not only in cinematography but also as a cultural implication that touches on disability studies and sexuality studies. Methodologically, this paper will, use crip theory, feminist film theories, and psychoanalysis to understand the representation of disabled sexuality in Blind Massage. The paper will be structured as follows. It will first review previous academic discussions on disabled sexuality in cinema. Then, it will elaborate on the invention of blind vision through scene and cinematography analyses and consider how Blind Massage echoes with a Mulveyian gaze theory in terms of marking the gaze as a normative power. Finally, I argue that blind vision could be regarded as an approach to reverse such power and release the potential resistance towards normativity in cinema, with a Lacanian revisit and reworking of the Mulveyian gaze theory

The Dilemma and Practice Paths of Multi-entity Participation in the Rural Living Environment—A Case Study of District Y in Chongqing

The remediation of the rural living environment is not only an important aspect of comprehensively promoting rural revitalization but also directly influences the villagers’ sense of happiness and attainment. This paper, taking District Y in Chongqing as an example, explores the practice paths of multi-entity coordinated governance in the rural living environment. The paper affirms the leading role of the government, participation responsibilities of the market, social organizations, and villagers, thereby constructing a multi-entity coordinated governance mechanism to effectively address the prominent problems currently faced

On the Energy-Efficiency Trade-off Between Active and Passive Communications with RIS-based Symbiotic Radio

Symbiotic radio (SR) is a promising technology of spectrum- and energy-efficient wireless systems, for which the key idea is to use cognitive backscattering communication to achieve mutualistic spectrum and energy sharing with passive backscatter devices (BDs). In this paper, a reconfigurable intelligent surface (RIS) based SR system is considered, where the RIS is used not only to assist the primary active communication, but also for passive communication to transmit its own information. For the considered system, we investigate the EE trade-off between active and passive communications, by characterizing the EE region. To gain some insights, we first derive the maximum achievable individual EEs of the primary transmitter (PT) and RIS, respectively, and then analyze the asymptotic performance by exploiting the channel hardening effect. To characterize the non-trivial EE trade-off, we formulate an optimization problem to find the Pareto boundary of the EE region by jointly optimizing the transmit beamforming, power allocation and the passive beamforming of RIS. The formulated problem is non-convex, and an efficient algorithm is proposed by decomposing it into a series of subproblems by using alternating optimization (AO) and successive convex approximation (SCA) techniques. Finally, simulation results are presented to validate the effectiveness of the proposed algorithm

Reconstructing parton distribution function based on maximum entropy method

A new method based on the maximum entropy principle for reconstructing the parton distribution function (PDF) from moments is proposed. Unlike traditional methods, the new method no longer needs to introduce any artificial assumptions. For the case of moments with errors, we introduce Gaussian functions to soften the constraints of moments. A series of tests are conducted to comprehensively evaluate the validity and reconstruction efficiency of this new method. And these tests indicate that our method is reasonable and can achieve high-quality reconstruction with at least the first six moments as input. Finally, we select a set of lattice QCD results regarding moments as input and provide reasonable reconstruction results.Comment: 6 pages, 8 figure

Effect of Polymerization Time and Pressure on the Molecular Weight and Molecular Weight Distribution of Polyethylene

Molecular weight and molecular weight distribution (MWD) of polyethylenes (PE) are important in determining their physical, mechanical, and rheological properties of end-products. In principle, molecular weight controls the mechanical properties of polymers, while MWD mainly affects the rheological properties. Therefore, it is necessary to control molecular weight and MWD to optimize the property and processibility of PE. The conventional Ziegler-Natta catalyst is still the main industrial catalyst for the production of PE. Hence, the control of MWD of PE produced using Ziegler-Natta catalyst has always been one of the most worthy research targets for industry and academy. The influence of the polymerization time and pressure on the molecular weight, MWD and relative MWD of PE in the ethylene polymerization with a MgCl2/SiO2/TiCl4/AlEt3 catalyst system in the slurry phase was studied by using gel permeation chromatography (GPC). It has been found that with the lapse of time increases the molecular weight and MWD of PE. However, the increase of the polymerization pressure increases the molecular weight and decreases the MWD of PE

Study on the structure and properties of new metallocene high branched polyethylene

The branching composition, distribution and melting crystallization properties of very low density polyethylenes (VLDPE) with different carbon chain length were studied by means of nuclear magnetic resonance (NMR) and differential scanning calorimetry (DSC). The average sequence length (nE, nH, nB), relative monomer distribution (RMD) and monomer reactivity ratio (rE, rH, rB) were selected to analyze the polymerization characteristics. The crystallization characteristics of wafer thickness (L), relative branching degree (S) and crystallinity (Xc) were discussed by means of SSA thermal classification method. It has been found that the comonomer content and branching degree of VLDPE products with hexene (C6) as co monomers is lower than that of butene (C4) copolymer products; while the crystallinity and lamellar thickness is higher than that of C4 products
