Turning couplets into a weapon of the Great Proletarian Cultural Revolution is also a creation by the masses in a revolutionary movement.

In this paper, we study the problem of protecting privacy in recommender systems. We focus on protecting the items rated by users and propose a novel privacy-preserving matrix factorization algorithm. In our algorithm, the user will submit a fake gradient to make the central server not able to distinguish which items are selected by the user. We make the Kullback–Leibler distance between the real and fake gradient distributions to be small thus hard to be distinguished. Using theories and experiments, we (...) show that our algorithm can be reduced to a time-delay SGD, which can be proved to have a good convergence so that the accuracy will not decline. Our algorithm achieves a good tradeoff between the privacy and accuracy. (shrink)

In a complex network, each edge has different functions on controllability of the whole network. A network may be out of control due to failure or attack of some specific edges. Bridges are a kind of key edges whose removal will disconnect a network and increase connected components. Here, we investigate the effects of removing bridges on controllability of network. Various strategies, including random deletion of edges, deletion based on betweenness centrality, and deletion based on degree of source or target (...) nodes, are used to compare with the effect of removing bridges. It is found that the removing bridges strategy is more efficient on reducing controllability than the other strategies of removing edges for ER networks and scale-free networks. In addition, we also found the controllability robustness under edge attack is related to the average degree of complex networks. Therefore, we propose two optimization strategies based on bridges to improve the controllability robustness of complex networks against attacks. The effectiveness of the proposed strategies is demonstrated by simulation results of some model networks. These results are helpful for people to understand and control spreading processes of epidemic across different paths. (shrink)

The surface grammar of reports such as ‘I have a pain in my leg’ suggests that pains are objects which are spatially located in parts of the body. We show that the parallel construction is not available in Mandarin. Further, four philosophically important grammatical features of such reports cannot be reproduced. This suggests that arguments and puzzles surrounding such reports may be tracking artefacts of English, rather than philosophically significant features of the world.

They will make some comments whenever we talk about the class line, but they deserve that! Speaking of class line, we are "people with vested interest.".

Philosophers disagree about what the folk concept of pain is. This paper criticises existing theories of the folk concept of pain, i.e. the mental view, the bodily view, and the recently proposed polyeidic view. It puts forward an alternative proposal – the polysemy view – according to which pain terms like “sore,” “ache” and “hurt” are polysemous, where one sense refers to a mental state and another a bodily state, and the type of polysemy at issue reflects two distinct but (...) related concepts of pain. Implications with respect to issues in philosophy of pain are also drawn. (shrink)

In The Specter of Materialism Petrus Liu examines what "materialism" means for progressive queer theory and Marxist approaches to China's postsocialist economy. Liu recasts the history of queer theory in light of the Beijing Consensus, arguing that North American queer theory's inability to sustain a materialist analysis is the result of its positioning of the United States, rather than China, as the focal point of contemporary global capitalism. Analyzing relations of gender and sexuality that have been reconfigured by China's global (...) capitalist accumulation-such as dagongmei (female migrant laborers in China's export-oriented sunbelt) and money boys (rural-to-urban sex workers)-Liu argues for a materialist queer theory that positions China at the center.

Against a backcloth of philosophical debates on science and technology, and in particular the viewpoints of Karl Marx, this three-volume set proposes to reconsider science and technology and explores how the philosophy of science and technology responds to scientific and technological evolutions and an ever-changing world. The first volume analyses Marx's reconsideration of science and technology in five parts: its positioning, its historical practice, alienation of science and technology, and its relationship with productivity and human liberty. In the second volume, (...) viewpoints and problems of scientism and anti-scientism are discussed, covering topics such as instrumental reason, scientific optimism and pessimism, irrationalism and the deconstruction of scientism. The final volume discusses complementary value choices, the loss and awakening of scientific culture and reveals a vison for a liberal and open world of science and technology. The volumes will appeal to scholars and students interested in Marxist philosophy, the philosophy of science and technology and topics related to scientific culture. (shrink)

The problem of consciousness has been an issue in philosophy of mind for decades, and in recent years panpsychism and panprotopsychism have gained attention among philosophers who are still dedicated to finding a complete explanation of consciousness. In this dissertation, I criticize panpsychism and panprotopsychism by examining their metaphysical plausibility and their epistemic prospects. Concerning the metaphysical plausibility of panpsychism and panprotopsychism, I explain the “combination problem” of panpsychism and criticize several major accounts of panpsychism and panprotopsychism that aim at (...) solving this problem, including Seager’s panpsychist infusionism, Goff’s phenomenal bonding proposal, and Coleman’s panqualityism. I also examine the proposal of motivating panpsychism and panprotopsychism by drawing support from the integrated information theory (IIT) of consciousness. I argue that this proposal to merge panpsychism or panprotopsychism with IIT does not work. Concerning the epistemic prospect of panpsychism and panprotopsychism, I raise concerns about whether panpsychism and panprotopsychism can guide a fruitful research program about the nature of consciousness. First, I argue that a theory based on Russellian Monism would not have a promising epistemic prospect. I compare Russellian Monism to Thomistic Hylomorphism and argue that Russellian Monism faces similar epistemic challenges that plagued Thomistic Hylomorphism. Since most theories of contemporary panpsychism and panprotopsychism rely on the metaphysical framework of Russellian Monism, the challenges to Russellian Monism also undermine the epistemic prospects of panpsychism and panprotopsychism. Second, I challenge the epistemic prospects of panpsychism and panprotopsychism by examining if there can be a viable method to study the consciousness of micro-level entities. After revisiting the reasoning process that guided the study of atoms, I argue that studying micro-level facts requires “analogies” that compare micro-level facts with macro-level models. Then I argue that an analogy that fits the need of panpsychism or panprotopsychism is hard to achieve, because we have no macro-level models to be compared to the hypothesized systems of micro-level consciousness.

Representationalism is a philosophical position which reduces all phenomenal conscious states to intentional states. However, starting from the phenomenal consciousness, the phenomenal intentionality theory provides an explanation of all sorts of intentionality. Against Michael Shim's interpretation, I argue that, although Hussserl's phenomenology is certainly considered as an antipode of strong representationalism, Husserl does not stand in opposition the weak representationalists, because Husserl maintains an essential connection between the senses of noemata and the hyletic data. In addition, Husserl's phenomenology is also (...) consistent with the phenomenal theory of intentionality. According to him, statically and genetically, all non-phenomenal intentional states take a recourse to phenomenal intentional states and eventually to sensual perceptions. (shrink)
