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)

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.

Due to the current COVID-19 pandemic, colleges and universities have implemented network teaching. E-learning engagement is the most important concern of educators and parents because this will directly affect student academic performance. Hence, this study focuses on students’ perceived family support and their e-learning engagement and analyses the effects of e-learning normative consciousness and behaviours and self-efficacy on the relationship between family support and e-learning engagement in college students. Prior to this study, the relationship between these variables was unknown. Four (...) structural equation models revealed the multiple mediating roles of e-learning normative consciousness and behaviours and self-efficacy in the relationship between family support and e-learning engagement. A total of 1317 college students (mean age = 19.51; 52.2% freshman) voluntarily participated in our study. The results showed that e-learning normative consciousness and behaviours and self-efficacy played significant and mediating roles between students’ perceived family support and their e-learning engagement. Specifically, these two individual variables fully mediated the relationship between students’ perceived family support and their e-learning engagement. The multiple mediation model showed that family members can increase family support of their children by creating a household environment conducive to learning, displaying positive emotions, demonstrating the capability to assist their children, advocating the significance of learning normative consciousness and behaviours and encouraging dedicated and efficient learning. The findings complement and extend the understanding of factors influencing student e-learning engagement. (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)

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)

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)

This article adopts Husserl’s transcendental phenomenology to explore the complex relationship between patients and physicians. It delves into the coexistence of two distinct voices in the realm of medicine and health: the “voice of medicine” and the “voice of life-world.” Divided into three sections, the article emphasizes the importance of shifting from a scientific-medical attitude to a more personalistic approach in physician–patient interactions. This shift aims to prevent depersonalization and desubjectification. Additionally, it highlights the equal and irreducible nature of patients (...) while acknowledging the vital role physicians hold in the realm of illness. The article stresses the need for a balanced and equitable relationship between both parties, rooted in the shared life-world. Moreover, empathy is underscored as a crucial element in fostering meaningful dialogue, wherein understanding diverse perspectives and attitudes towards illness is paramount. The article argues that differences between patients and physicians are necessary for empathy, while shared similarities form its foundation. Ultimately, a harmonious relationship facilitates empathy and enables the constitution of a new sense of life for both patients and physicians. (shrink)

This article assumes that a profession is a number of individuals in the same occupation voluntarily organized to earn a living by openly serving a moral ideal in a morally-permissible way beyond what law, market, morality, and public opinion would otherwise require. Our question is whether the concept of profession may have a far wider range than the term, so that, for example, pointing out that a certain language lacks a word for “profession” in our sense, is not enough to (...) show that those who speak the language also lack the concept. We believe the survey of 71 Chinese reported here begins to answer that question. This article has four parts. The first describes who was interviewed, how, when, and so on. The second describes some important features of the survey’s questions, explaining how the questions track the concept of profession. The third part reports and interprets the results relevant to our question. The forth defends a tentative answer to the question with which we began—arguing the survey supports the claim that China has a profession of engineering. This article should serve as a “proof of concept”, that is, a model for similar studies around the world both of engineering and of other occupations thought to be professions. (shrink)

Modern socialist economic reforms which center on the establishment of a commodity based economic system, demand a reconsideration of human nature. Marxism and human sociobiology give different answers to questions about human nature, but neither is complete in itself. It seems timely, therefore, to suggest that a combination of biological understanding with a Marxist-based social understanding would produce a more adequate notion of human nature, thereby helping us to resolve a number of problems posed by reforms currently taking place in (...) socialist countries. We might also hope to face new challenges posed in the future. (shrink)

The autophagy initiation complex is brought about via a highly ordered and stepwise assembly process. Two crucial signaling molecules, mTORC1 and AMPK, orchestrate this assembly by phosphorylating/dephosphorylating autophagy‐related proteins. Activation of Atg1 followed by recruitment of both Atg9 vesicles and the PI3K complex I to the PAS (phagophore assembly site) are particularly crucial steps in its formation. Ypt1, a small Rab GTPase in yeast cells, also plays an essential role in the formation of the autophagy initiation complex through multiple regulatory (...) pathways. In this review, our primary focus is to discuss how signaling molecules initiate the assembly of the autophagy initiation complex, and highlight the significant roles of Ypt1 in this process. We end by addressing issues that need future clarification. (shrink)

With the development of teachers’ psychological cognition, the moral education curriculum develops as per the changes in times. Currently, a resurgence of interest on studying teachers’ perceptions of the moral education curriculum has observed. This is because moral education curriculum of each country plays a unique role in the overall design of the country’s education curriculum. However, studies on teachers’ perceptions of the moral education curriculum are scarce, and no framework has been developed to guide the teaching and learning of (...) teachers for the moral education curriculum for schools. The moral education curriculum serves as one of the main vehicles for value education, with teachers as direct executors. It can influence the overall development of the school system and long-term development of a country. Thus, in this paper, we reviewed current literature related to teachers’ perceptions of the moral education curriculum and developed future trends considering teachers’ perceptions of the moral education curriculum in improving existing moral education programs in a country. We identified a list of keywords related to moral education curriculum and teacher perceptions and relevant to the scope of this study. These keywords were used to search the articles from the Scopus and WoS studies. Overall, 32 papers meeting the search criteria were retrieved. Further, we conducted thematic studies, and four themes were successfully identified: the model of teacher perceptions of moral and national education, the dimensions of the teacher ethics model, teaching strategies, and the role of teachers. The results of this study suggested a new framework for research trends in teachers’ perception models, particularly toward the moral education curriculum. This study contributed to the knowledge regarding teaching and learning approaches of moral education considering teachers’ perceptions of the moral education curriculum. The findings of study would benefit future studies and would improve the implementation of a country’s moral education program. (shrink)

Considering that the development of urbanization cannot be separated from the application of landscape pattern evolution, in order to improve the development level of ecocity, a modeling analysis of ecological urban landscape pattern evolution based on multisource remote sensing data is proposed. Taking ecotype city as the research object, the remote sensing images of ecological urban landscape pattern are screened by using multisource remote sensing data and nonremote sensing data as the basic data. CA-Markov model is constructed and the evolution (...) of ecological urban landscape pattern is analyzed. The experimental results show that, from 2005 to 2020, the development level of urbanization process is higher and higher and the area of building land patches is increasing, which reduces the fragmentation of building land patches. However, the landscape of cultivated land and green space is less and less, and the distribution of the patches also causes uneven phenomenon, which leads to the gradual decline of ecological urban landscape diversity. In the ecological urban landscape pattern, the degree of fragmentation and diversity of urban landscape is reduced due to the high connection and coverage of the construction land. (shrink)

Early and later Confucians, known in Chinese as the “ruists” school of ancient origins, perceived the idea of “harmony” as a fundamental concept that lies at the basis of self-cultivation, society and governance. In modern times this idea still plays in one or another form a dominant note in Chinese politics and social life. The article attempts to search for causes of the significance of “harmony” by focusing on analyzing two pivotal Confucian texts compiled in the Han dynasty, namely, Records (...) of Music [Yue ji 樂記] and Divination of Music [Yue wei 樂緯]. The analysis shows that ruists belonging to Zhou dynasty’s imperial class of music officials, gradually developed the aesthetics of music into a complex idea of "harmony" that contains the highest aesthetical way—“Dao”—which guides both the whole universe as well as the evolution of human society.

As a result of simultaneous developments, including the proliferation of opportunities for online feedback, the application of discourse ethics to journalism, and a greater emphasis on journalistic accountability, the time is ripe for revisiting opportunities that online mechanisms provide for holding journalists accountable to audiences. This paper proposes recommendations to guide hosting online comments in light of the Habermasian framework of discourse ethics developed by Glasser and Ettema (2008). It also explores the limits of such approaches in nations with different (...) press models, such as the development model as practiced in China. (shrink)

This article describes a representation-based framework of distributed cognition. This framework considers distributed cognition as a cognitive system whose structures and processes are distributed between internal and external representations, across a group of individuals, and across space and time. The major issue for distributed research, under this framework, are the distribution, transformation, and propagation of information across the components of the distributed cognitive system and how they affect the performance of the system as a whole. To demonstrate the value of (...) this representation-based approach, the framework was used to describe and explain an important, challenging, and controversial issue — the concept of affordance.
