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)

Truth pluralism is the view that there is more than one truth property. The strong version of it (i.e. strong pluralism) further contends that no truth property is shared by all true propositions. In this paper, I help strong pluralism solve two pressing problems concerning mixed discourse: the problem of mixed inferences (PI) and the problem of mixed compounds (PC). According to PI, strong pluralism is incompatible with the truth- preservation notion of validity; according to PC, strong pluralists cannot find (...) any appropriate truth property for mixed compound propositions, whose atomic constituents are from different domains of discourse (e.g., <sky is blue and chocolate is tasty>). I argue that the strong pluralist is motivated to take the truth predicate in truth-involving universal statements to be deflationary to avoid the two pressing problems. Such a move entails that the truth predicate in the platitude of validity (V) for any argument, it is valid if and only if necessarily its conclusion is true when its premises are all true does not denote any substantive truth property. Instead, it is merely an expressive device to help people generalize instances of (V) to (V). Analogous stories hold for the truth predicate in the platitudes of compound (e.g., conjunction). The upshot is that, the strong pluralist can solve PI and PC by further conceding that mixed compounds are true/false in a deflationary way. (shrink)

ABSTRACTMobilizing Foucault’s genealogy, this article investigates how an “ethics event”—the involvement by some sell-side financial analysts in the United States and United Kingdom across the past two decades in corporate governance—emerged. It is found that the complex relations formed between specific historical precedents, normative discourses, and fields of power rendered certain issues in financial markets morally problematic and constructed analysts’ corporate governance work as a potential solution. Contributing to research in finance ethics, this article develops a novel perspective to conceptualize (...) the rise of ethically relevant practices in financial markets, focusing on how ethical problems and their solutions are outcomes of discursive construction and power relations. This article also revises our understanding of the boundary between technical norms and moral norms in financial markets. When ethical crises occur, it is argued, transforming technical practices and revising the technical norms adopted by financial professionals has the potential to tackle ethical concerns. (shrink)

In both political science and political theory, democratization has largely been considered a problem for non-liberal democratic countries. Drawing on Chinese political thinker Jiwei Ci’s writings on freedom, democracy, agency, plausibility, and legitimacy, I critically reconstruct Ci’s theory of democratization and his method of theorizing. I argue that a normative account of democratization is embedded in Ci’s political thought, which is based upon a philosophical anthropology of the modern man and focuses on broadening political possibilities in a given society. Ci’s (...) theory allows us to think about democratization beyond the binary of democracy and authoritarianism, as his theory places democratization as an inherent and persistent challenge for all political communities.

How should insecure leaders deal with labor rights in the face of an economic downturn? Economic theory suggests that suppressing labor rights boosts the economy and that economic growth also dampens violent political opposition. As a result, the suppression of labor rights should contribute to more job security for leaders. However, some other scholars maintain that more repression actually increases the probability of opposition. As a result, the policy implication of this argument is that leaders would be better off if (...) they choose to improve the protection of labor rights. Our simple formal model demonstrates that the second argument is more likely to be the case. The probit analysis of 146 countries from 1984 to 2004 bears out this prediction. We also find that this relationship is stronger in non-democracies than in democracies. Our study appears to provide some support to Bueno de Mesquita et al.’s statement that policies that are good for political survival may not necessarily be good for the economy. (shrink)

Internet addiction is a growing social problem with negative mental and social outcomes; the present study examined whether rejection sensitivity mediates the relationship between interparental conflict and adolescent IA and the moderating role of school connectedness. One thousand and seven adolescents anonymously completed questionnaires to assess interparental conflict, school connectedness, rejection sensitivity, IA, and demographic information. The model results showed that: the positive association between interparental conflict and adolescent IA was partially mediated by rejection sensitivity; this indirect link was moderated (...) by the school connectedness and was stronger for adolescents with high school connectedness. The results provide support for the attachment theory that high interparental conflict could increase adolescents’ rejection sensitivity, and high school connectedness plays a double-edged role that adolescents show more rejection sensitivity while reporting high interparental conflict and high school connectedness.

This study investigates the determinants of the ratification of International Covenant on Economic, Social, and Cultural Rights (ICESCR). To do so, it proposes an explanation that postulates that states employ treaty ratification as a device to signal their resolve to implement polices required by the treaty at issue in order to appease demanding domestic constituencies, predicting that states with lower compliance capacity tend to commit faster than states with higher compliance capacity. Applying this explanation to the ICESCR leads to two (...) expectations. First, the larger government spending a proxy of high compliance capacity is hypothesized to delay the ratification process. Second, states with the unitary system are expected to ratify the ICESCR more promptly because the centralized power structure in unitary states significantly restricts the pursuit of the policy autonomy by minorities at local level that the right to self-determination entails. The Cox proportional hazard analysis lends support to both hypotheses. (shrink)

This study aimed to analyze the relations between class competition and primary school students’ academic achievement, considering the possible mediating roles of learning anxiety and learning engagement. Participants were 1,479 primary school students from four primary schools in Zhejiang, China. We analyzed participants’ scores for class competition, learning anxiety, and learning engagement and their last two final exam scores. Class competition did not directly predict academic achievement, but indirectly affected academic achievement through learning anxiety and learning engagement. There were three (...) effect paths: class competition negatively predicted academic achievement by increasing learning anxiety; class competition positively predicted academic achievement by promoting learning engagement; and class competition affected academic achievement through multiple mediating effects of learning anxiety and learning engagement. This study highlights the important roles of learning anxiety and learning engagement in class competition and academic achievement, which have theoretical and practical significance. (shrink)

Short-term traffic flow prediction is an effective means for intelligent transportation system to mitigate traffic congestion. However, traffic flow data with temporal features and periodic characteristics are vulnerable to weather effects, making short-term traffic flow prediction a challenging issue. However, the existing models do not consider the influence of weather changes on traffic flow, leading to poor performance under some extreme conditions. In view of the rich features of traffic data and the characteristic of being vulnerable to external weather conditions, (...) the prediction model based on traffic data has certain limitations, so it is necessary to conduct research studies on traffic flow prediction driven by both the traffic data and weather data. This paper proposes a combined framework of stacked autoencoder and radial basis function neural network to predict traffic flow, which can effectively capture the temporal correlation and periodicity of traffic flow data and disturbance of weather factors. Firstly, SAE is used to process the traffic flow data in multiple time slices to acquire a preliminary prediction. Then, RBF is used to capture the relation between weather disturbance and periodicity of traffic flow so as to gain another prediction. Finally, another RBF is used for the fusion of the above two predictions on decision level, obtaining a reconstructed prediction with higher accuracy. The effectiveness and robustness of the proposed model are verified by experiments. (shrink)

Computer vision is widely used in manufacturing, sports, medical diagnosis, and other fields. In this article, a multifeature fusion error action expression method based on silhouette and optical flow information is proposed to overcome the shortcomings in the effectiveness of a single error action expression method based on the fusion of features for human body error action recognition. We analyse and discuss the human error action recognition method based on the idea of template matching to analyse the key issues that (...) affect the overall expression of the error action sequences, and then, we propose a motion energy model based on the direct motion energy decomposition of the video clips of human error actions in the 3 Deron action sequence space through the filter group. The method can avoid preprocessing operations such as target localization and segmentation; then, we use MET features and combine with SVM to test the human body error database and compare the experimental results obtained by using different feature reduction and classification methods, and the results show that the method has the obvious comparative advantage in the recognition rate and is suitable for other dynamic scenes.

This article proposes an interpretation of the ‘Thesis that Things do not Shift’ (_Wu bu qian lun,_ 物不遷論) of the early Chinese Buddhist philosopher Sengzhao. We understand Sengzhao to be proposing a version of the philosophy of time found in Sarvāstivāda Abhidharma, and then interpreting statements about time from Mahāyāna texts in light of that account. But whatever his limitations as a cross-cultural interpreter, we find Sengzhao surprisingly impressive philosophically, as he proposes a view that is noticeably more advanced towards (...) a modern conception of time than the accounts found in South Asian Buddhist sources. Ironically, his earnest efforts to present his view as falling within the Mahāyāna may have functioned to conceal Sengzhao’s true philosophical achievement. (shrink)

In recent years, the translation of Debray’s writings and the study of his media thoughts have become increasingly popular in China, but the ‘medium’ in his media discourse has never been clarified. Debray pointed out that the focus of the media is ‘mediation’, which actually reveals a new way of thinking and reasoning. He then proposed four stages of mediological reasoning: Message, Medium, Milieu and Mediation. This article believes that based on this framework (i.e. 4M), Debray used McLuhan’s theory as (...) a hub for analysis and launched a set of research methods and tools aimed at exploring the multiple nature of medium and message on the sense of interaction between culture and technology, which also involved the utility of ‘mediasphere’ as an exploration principle to question the past and future of mankind and the media conditions. This approach provides an avenue for us to understand ourselves and transmissions in different space-time categories at both practical and theoretical levels. This article emphasizes that it is better not to interpret Debray’s thoughts as a theory parallel to the existing medium theories because its focus is on research approaches rather than arguments. Besides, although Debray’s medium theory is based on his experience and thinking in Europe and Latin America, there are reasons for the publicity of Debray’s ideology in China. From the perspective of history, culture and human geography, Chinese civilization can be said to contain rich ideological resources of mediation. This is of great significance to re-understand China’s history and reality in the new context of globalization, and to discover the global value of China’s experience. (shrink)

The mounting pollution burden has raised the need for renewable energy demand throughout the world. The study aims to explore the effect of public debt on renewable energy consumption for selected 23 Asian economies for the time period 1990–2019. Long-run empirical findings of the group-wise symmetric ARDL model reveal that increasing public debt results in declining renewable energy consumption. However, findings of the long-run group-wise asymmetric ARDL model reveal that positive shock in public debt reduces renewable energy consumption, and negative (...) shock in public debt results in increasing renewable energy consumption. The economy-wise empirical findings of the FMOLS model reveal that an increase in public debt results in increased renewable energy consumption in nine economies and decreased renewable energy consumption in six economies. The asymmetric FMOLS findings reveal that positive shock in public debt increases renewable energy consumption in nine economies and also decreases renewable energy consumption in nine economies. However, a negative shock in public debt increases renewable energy consumption in 12 economies and decreases renewable energy consumption in 5 economies. Additionally, this research provides numerous policy implications for renewable energy sources in Asian economies. Asian governments should use public debt for the consumption of renewable energy resources. (shrink)

In the spirit of Von Neumann and Morgenstern (Theory of games and economic behavior, Princeton University Press, Princeton, 1944), we introduce a notion of network stability. We study the structure of stable economic networks and their associated stable payoff allocations by analyzing the conditions under which complete networks and star networks (both with desirable property of inclusiveness) are stable. We also address conditions for existence and uniqueness of stable set of networks.

The kin selection hypothesis posits that male androphilia (male sexual attraction to adult males) evolved because androphilic males invest more in kin, thereby enhancing inclusive fitness. Increased kin-directed altruism has been repeatedly documented among a population of transgendered androphilic males, but never among androphilic males in other cultures who adopt gender identities as men. Thus, the kin selection hypothesis may be viable if male androphilia was expressed in the transgendered form in the ancestral past. Using the Standard Cross-Cultural Sample (SCCS), (...) we examined 46 societies in which male androphilia was expressed in the transgendered form (transgendered societies) and 146 comparison societies (non-transgendered societies). We analyzed SCCS variables pertaining to ancestral sociocultural conditions, access to kin, and societal reactions to homosexuality. Our results show that ancestral sociocultural conditions and bilateral and double descent systems were more common in transgendered than in non-transgendered societies. Across the entire sample, descent systems and residence patterns that would presumably facilitate increased access to kin were associated with the presence of ancestral sociocultural conditions. Among transgendered societies, negative societal attitudes toward homosexuality were unlikely. We conclude that the ancestral human sociocultural environment was likely conducive to the expression of the transgendered form of male androphilia. Descent systems, residence patterns, and societal reactions to homosexuality likely facilitated investments in kin by transgendered males. Given that contemporary transgendered male androphiles appear to exhibit elevated kin-directed altruism, these findings further indicate the viability of the kin selection hypothesis. (shrink)

A prefrontal control system that is less mature than the limbic reward system in adolescence is thought to impede self-regulatory abilities, which could contribute to poor dietary choices and obesity. We, therefore, aimed to examine whether structural morphology of the prefrontal cortex and the amygdala are associated with dietary decisions and obesity in children and adolescents. Seventy-one individuals between the ages of 8–22 years participated in this study; each participant completed a computer-based food choice task and a T1- and T2-weighted (...) structural brain scans. Two indices of obesity were assessed, including age- and sex-specific body mass index and waist-to-height ratio. The behavioral task included rating 60 food stimuli for tastiness, healthiness, and liking. Based on each participant’s self-ratings, 100 binary food choices were then made utilizing a computer mouse. Dietary “self-control” was calculated as the proportion of trials where the individual chose the healthier food item over the total number of trials. Cortical thickness and amygdala subnuclei volumes were quantified using FreeSurfer 6.0 and CIT168 atlas, respectively. We found that WHtR was negatively associated with the thickness of bilateral superior frontal, left superior temporal, right insula, and right inferior temporal regions. We also found WHtR to be positively associated with the volume of the central nucleus region of the amygdala, after adjusting for the hemisphere, age, sex, and intracranial volumes. A similar data pattern was observed when BMIz was used. Moreover, we found that across all participants, thinner right superior frontal cortex and larger left CEN volumes predicted lower dietary self-control. These results suggest that differential development of the PFC and amygdala relate to obesity and dietary self-control. Further longitudinal studies are merited to determine causal relationships among altered PFC to amygdala neural circuitry, dietary self-control, and obesity. (shrink)

Recently, the pandemic caused by COVID-19 is severe in the entire world. The prevention and control of crimes associated with COVID-19 are critical for controlling the pandemic. Therefore, to provide efficient and convenient intelligent legal knowledge services during the pandemic, we develop an intelligent system for legal information retrieval on the WeChat platform in this paper. The data source we used for training our system is “The typical cases of national procuratorial authorities handling crimes against the prevention and control of (...) the new coronary pneumonia pandemic following the law”, which is published online by the Supreme People’s Procuratorate of the People’s Republic of China. We base our system on convolutional neural network and use the semantic matching mechanism to capture inter-sentence relationship information and make a prediction. Moreover, we introduce an auxiliary learning process to help the network better distinguish the relation between two sentences. Finally, the system uses the trained model to identify the information entered by a user and responds to the user with a reference case similar to the query case and gives the reference legal gist applicable to the query case.

Bioethical debates on the use of human embryos and oocytes for stem cell research have often been criticized for the lack of empirical insights into the perceptions and experiences of the women and couples who are asked to donate these tissues in the IVF clinic. Empirical studies that have investigated the attitudes of IVF patients and citizens on the donation of their embryos and oocytes have been scarce and have focused predominantly on the situation in Europe and Australia. This article (...) examines the viewpoints on the donation of embryos for stem cell research among IVF patients and students in China. Research into the perceptions of patients is based on in-depth interviews with IVF patients and IVF clinicians. Research into the attitudes of students is based on a quantitative survey study. The empirical findings in this paper indicate that perceptions of the donation of human embryos for stem cell research in China are far more diverse and complex than has commonly been suggested. Claims that ethical concerns regarding the donation and use of embryos and oocytes for stem cell research are typical for Western societies but absent in China cannot be upheld. The article shows that research into the situated perceptions and cultural specificities of human tissue donation can play a crucial role in the deconstruction of politicized bioethical argumentation and the assumptions about “others” that underlie socio-ethical debates on the moral dilemmas of technology developments in the life sciences.

Social exclusion has a significant impact on cognition, emotion, and behavior. Some behavioral studies investigated how social exclusion affects pain empathy. Conclusions were inconsistent, and there is a lack of clarity in identifying which component of pain empathy is more likely to be affected. To investigate these issues, we used a Cyberball task to manipulate feelings of social exclusion. Two groups participated in the same pain empathy task while we recorded event-related potentials when participants viewed static images of body parts (...) in painful and neutral situations. The results showed early N2 differentiation between painful and neutral pictures in the central regions in both groups. The pattern at the late controlled processing stage was different. Parietal P3 amplitudes for painful pictures were significantly smaller than those for neutral pictures in the social exclusion group; they did not differ in the social inclusion group. We observed a parietal late positive potential differentiation between painful and neutral pictures in both groups. LPP amplitudes were significantly smaller in the social exclusion group than those in the social inclusion group for painful stimuli. Our results indicate that social exclusion does not affect empathic responses during the early emotional sharing stage. However, it down-regulates empathic responses at the late cognitive controlled stage, and this modulation is attenuated gradually. The current study provides neuroscientific evidence of how social exclusion dynamically influences pain empathy. (shrink)
