With the increasing volume of web services in the cloud environment, Collaborative Filtering- based service recommendation has become one of the most effective techniques to alleviate the heavy burden on the service selection decisions of a target user. However, the service recommendation bases, that is, historical service usage data, are often distributed in different cloud platforms. Two challenges are present in such a cross-cloud service recommendation scenario. First, a cloud platform is often not willing to share its data to other (...) cloud platforms due to privacy concerns, which decreases the feasibility of cross-cloud service recommendation severely. Second, the historical service usage data recorded in each cloud platform may update over time, which reduces the recommendation scalability significantly. In view of these two challenges, a novel privacy-preserving and scalable service recommendation approach based on SimHash, named SerRecSimHash, is proposed in this paper. Finally, through a set of experiments deployed on a real distributed service quality dataset WS-DREAM, we validate the feasibility of our proposal in terms of recommendation accuracy and efficiency while guaranteeing privacy-preservation.

Assuming the existence of a measurable cardinal, we define a hierarchy of Ramsey cardinals and a hierarchy of normal filters. We study some combinatorial properties of this hierarchy. We show that this hierarchy is absolute with respect to the Dodd-Jensen core model, extending a result of Mitchell which says that being Ramsey is absolute with respect to the core model.

Article aims to explore Augustine's "two cities" theory. First, a brief discussion of the "City of God" writing background and the main structure; Secondly, in both religious and secular aspects of life on the analysis of the "City of God" on the "two cities" of the main points; again, three perspectives of the "two cities" theory of history and ideological background. Although the "two cities" doctrine embodies a form with two points tend to think, but both different from the ontological (...) dualism and the dualism of body and soul, but also avoids the complex social reality for too absolute two points. The focus of this study is Augustine's doctrine of the "Two Cities." The first part treats the background and the structure of the City of God. In the second and the third part, the essay examines both the religious and the temporal aspect of this doctrine. Finally, the historical and intellectual background of the doctrine is discussed. The author argues that even though the doctrine of the "Two Cities" manifests a dualistic tendency in the thought of Augustine, it can hardly be labeled as a dualism. (shrink)

By drawing on extensive interviews with business founders and CEOs this book explores the complexities and dynamics of business and social relations responsible for present-day China's economic vibrancy. It makes an original contribution both through its empirical richness and theoretical innovations on trust, social networks, crisis and gender.

本书是文化哲学著述,对人类历史发展中的许多文化(精神)现象作了个性化的阐释,如人类开始为何要将自然神化,为何既需要上帝又需要尼采,为何后来又否定了神等问题。.

Yi-He is universal symbol of Chinese philosophy, it contains two thoughts of “Yi” and “He”. Thought of “Yi” represents idea of change in Chinese philosophy，thought of “He” represents idea of harmony in Chinese philosophy. “Philosophy of Yi-He” is dialectical synthesis of thought of “Yi” and thought of “He”, as well as the unique nature of Chinese philosophy thought. It embodies the deep structure of Chinese cultural spirit and the innovative pattern of Chinese philosophy thought. At present, “philosophy of Yi-He” conforms (...) to the topic of the age, i.e. developing in all-round and coordinating way and constructing harmonious society. It constitutes Chinese philosophy idea which reflects and criticizes modern civilization and creating viewpoint on harmonious development. “Philosophy of Yi-He” calls on harmonious world and constructs harmonious development idea in the relationship between human being and nature, human being and society, human being and themselves, human being and civilization. The viewpoint on harmonious development of Chinese philosophy aims at creating an ideal of harmonious world. (shrink)

Fine’s discussion of McTaggart’s paradox and tense realism may be the most significant progress in the philosophy of time in recent years. Fine reformulates McTaggart’s paradox and develops a novel realist theory called fragmentalism. According to Fine, one major advantage of fragmentalism is its ability to account for the connection between reality and tensed truths. I will argue that fragmentalism cannot give an adequate account of this connection. The reason is that while external relations between fragments are required by this (...) kind of account, these relations are not allowed in fragmentalism. (shrink)

We investigate the dynamics of a nonautonomous stochastic SIS epidemic model with nonlinear incidence rate and double epidemic hypothesis. By constructing suitable stochastic Lyapunov functions and using Has’minskii theory, we prove that there exists at least one nontrivial positive periodic solution of the system. Moreover, the sufficient conditions for extinction of the disease are obtained by using the theory of nonautonomous stochastic differential equations. Finally, numerical simulations are utilized to illustrate our theoretical analysis.

The Myelin Regulator Factor (MYRF) is a master regulator governing myelin formation and maintenance in the central nervous system. The conservation of MYRF across metazoans and its broad tissue expression suggest it has functions extending beyond the well‐established role in myelination. Loss of MYRF results in developmental lethality in both invertebrates and vertebrates, and MYRF haploinsufficiency in humans causes MYRF‐related Cardiac Urogenital Syndrome, underscoring its importance in animal development; however, these mechanisms are largely unexplored. MYRF, an unconventional transcription factor, begins (...) embedded in the membrane and undergoes intramolecular chaperone mediated trimerization, which triggers self‐cleavage, allowing its N‐terminal segment with an Ig‐fold DNA‐binding domain to enter the nucleus for transcriptional regulation. Recent research suggests developmental regulation of cleavage, yet the mechanisms remain enigmatic. While some parts of MYRF's structure have been elucidated, others remain obscure, leaving questions about how these motifs are linked to its intricate processing and function. (shrink)

We prove that Rado's Conjecture implies that the nonstationary ideal on ω 1 is presaturated.

Work procrastination is a retreat behavior associated with negative cognitive experience and it results in great losses to individual as well as organizational development. Understanding the antecedents of employees’ work procrastination behavior contributes to lower frequency of its occurrence. This research builds a dual-moderated mediation model from the perspective of cognitive appraisal theory and explored work procrastination behavior of employees subjected to abusive supervision. With 378 valid returned questionnaires, data collected from 32 companies in Beijing, Shanghai, Tianjin, and Chongqing supports (...) our hypotheses. This result has enriched the understanding of work procrastination behavior and provided practical implications to avoide its negative effects. (shrink)

Ethical voice involves individuals’ perceptions of what is right and what is wrong. Although prior research has investigated the impacts of individual-level prohibitive ethical expression on personal outcomes, there has been limited examination of ethical voice at the group level. Our study examines how and when different types of ethical voice influence group outcomes. Using data gathered from 363 participants from 61 groups in two Chinese companies, the results reveal that promotive and prohibitive ethical voices at the group level exert (...) opposing influences on group moral transitive motivation. Group moral transitive motivation serves as a mediating factor in the association between the two types of ethical voice and group ethical behaviors (GEB). In addition, group faultlines moderate the impact of promotive ethical voice and prohibitive ethical voice on group moral transitive motivation and on GEB (via group moral transitive motivation). Our study extends the focus of research from a single type of ethical voice at the individual level to multiple types at the group level. The findings contribute to the body of knowledge regarding group ethical voice (GEV) by articulating its mediating mechanism as well as its boundary condition. This research provides valuable insights for researchers and managers by offering a comprehensive understanding about the role of different types of GEV and how to reform GEV. (shrink)
