This paper is concerned with the target tracking problem of an autonomous surface vehicle in the presence of a maneuvering target. The velocity information of target is totally unknown to the follower vehicle, and only the relative distance and angle between the target and follower are obtained. First, a reduced-order extended state observer is used to estimate the unknown relative dynamics due to the unavailable velocity of the target. Based on the reduced-order extended state observer, an antidisturbance guidance law for (...) target tracking is designed. The input-to-state stability of the closed-loop target tracking guidance system is analyzed via cascade theory. Furthermore, the above result is extended to the case that collisions between the target and leader are avoided during tracking, and a collision-free target tracking guidance law is developed. The main feature of the proposed guidance law is twofold. First, the target tracking can be achieved without using the velocity information of the target. Second, collision avoidance can be achieved during target tracking. Simulation results show the effectiveness of the proposed antidisturbance guidance law for tracking a maneuvering target with the arbitrary bounded velocity. (shrink)

ABSTRACT Public discourse under authoritarian rule is not monolithic. Yet how popular rhetoric engages with the hegemonic rhetoric in the same discursive space remains understudied. This article examines the rhetoric of a standup comedy show in China, streamed online and widely popular among Chinese millennials, to understand how alternative views on social issues can coexist with the hegemonic rhetoric. Using critical discourse analysis, it argues that some standup comedy performances transgress the hegemonic rhetoric of 'positive energy' without outright subversion. Comedians (...) use subversive affirmation, self-deprecation, ambiguity, absurd fantasy, and irony to present alternative viewpoints on social issues of broad interest, such as the neoliberal work culture and gender norms. The subtle yet powerful transgressions introduce previously marginal views into the public discourse, diminishing the aura of wide acceptance and authority assumed by the hegemonic rhetoric. The standup comedy performances thus open up new discursive pathways towards non-state-sanctioned views on important social issues. (shrink)

Against the background that the top-level semantic framework of Chinese traditional culture is not comprehensive and unified, this study aims to preserve and disseminate cultural heritage information about Chinese traditional culture through the development of a domain ontology which is constructed from ancient books. A combination of top-down and bottom-up approaches was used to construct the ontology for Chinese traditional culture. An investigation of historians’ needs, and LDA topic clustering model were conducted, understanding the specific needs of historians, collecting the (...) topic, concepts and relationships. CIDOC CRM was reused to construct the basic framework of CTCO. Ontology structure and function were adopted to evaluate the effectiveness of CTCO. Evaluation results show that the ontology meets all the quality criteria of OntoMetrics, and the experts agreed on content representation. CTCO contributes to the organization of traditional Chinese culture and the construction of related databases. The study also forms a common path and puts forward proposals for the construction of domain ontology, which has great social relevance. (shrink)

If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.

According to evidentialist views, credence in a proposition p should be proportional to the degree of evidential support that one has in favor of p. However, empirical evidence suggests that our credences are systematically sensitive to practical factors. In this article, I provide a cost–benefit analysis of credences' practical sensitivity. The upshot of this analysis is that credences sensitive to practical factors fare better than practically insensitive ones along several dimensions. All things considered, our credences should be sensitive to practical (...) factors. (shrink)

The relation between quantum collapse, consciousness and superluminal communication is analyzed. As we know, quantum collapse, if exists, can result in the appearance of quantum nonlocality, and requires the existence of a pre- ferred Lorentz frame. This may permit the realization of quantum superluminal communication (QSC), which will no longer result in the usual causal loop in case of the existence of a preferred Lorentz frame. The possibility of the existence of QSC is further analyzed under the assumption that quantum (...) collapse is a real process. We demonstrate that the combination of quantum collapse and the consciousness of the observer will permit the observer to distinguish nonorthogonal states in principle. This provides a possible way to realize QSC. Some implications of the existence of QSC are briefy discussed. (shrink)

Numerous studies have found that selective attention affects category learning. However, previous research did not distinguish between the contribution of focusing and filtering components of selective attention. This study addresses this issue by examining how components of selective attention affect category representation. Participants first learned a rule‐plus‐similarity category structure, and then were presented with category priming followed by categorization and recognition tests. Additionally, to evaluate the involvement of focusing and filtering, we fit models with different attentional mechanisms to the data. (...) In Experiment 1, participants received rule‐based category training, with specific emphasis on a single deterministic feature (D feature). Experiment 2 added a recognition test to examine participants’ memory for features. Both experiments indicated that participants categorized items based solely on the D feature, showed greater memory for the D feature, were primed exclusively by the D feature without interference from probabilistic features (P features), and were better fit by models with focusing and at least one type of filtering mechanism. The results indicated that selective attention distorted category representation by highlighting the D feature and attenuating P features. To examine whether the distorted representation was specific to rule‐based training, Experiment 3 introduced training, emphasizing all features. Under such training, participants were no longer primed by the D feature, they remembered all features well, and they were better fit by the model assuming only focusing but no filtering process. The results coupled with modeling provide novel evidence that while both focusing and filtering contribute to category representation, filtering can also result in representational distortion.

The unique relation between logic and truth is crucial for understanding Fregean conception of logic. Frege has an insight that the nature of logic resides in the “truth“, which he finally locates in the assertoric-force of a sentence. Though Frege admits that assertoric-force is ineffable in ordinary language, he coins in his conceptual notation for such a force a much-disputed sign, i.e., judgment-stroke. In this paper, I will try to demonstrate that judgment-stroke is not adequate for the task its inventor (...) has assigned to it. Accordingly, it is misconceived and inconducive to clarify Frege’s vague insight into the protorelation. The mistake of judgment-stroke for the sign of assertoric-force has its root in Frege’s ignorance of the significant difference between “judgment” and assertion”, which will be elucidated at length in the light of Husserl’s theory of “doxic-modification“. In the end, based on a further elucidation of the activity of assertion, I will advance a tentative interpretation of the vague insight Frege has concerning the protorelation. (shrink)

Although several articles have investigated ethical product attributes, earlier research has not empirically examined different benefits offered by ethical attributes. This study demonstrates that ethical attributes have functional benefits as well as symbolic benefits. More importantly, when the ethical attribute benefit is congruent with the product category benefit, ethical attributes improve product evaluations. In addition, products with a higher degree of physical contact with consumers are affected more positively by benefit congruity of ethical attributes. For products with lower degree of (...) physical contact, benefit congruity of ethical attributes still has a positive impact, but not for consumers who have strong price–quality beliefs. (shrink)

It is commonly believed that Edmund Husserl (1859-1938), well known as the founder of phenomenology and as the teacher of Heidegger, was unable to free himself from the framework of a classical metaphysics of subjectivity. Supposedly, he never abandoned the view that the world and the Other are constituted by a pure transcendental subject, and his thinking in consequence remains Cartesian, idealistic, and solipsistic. The continuing publication of Husserl’s manuscripts has made it necessary to revise such an interpretation. Drawing upon (...) both Husserl’s published works and posthumous material, Husserl’s Phenomenology incorporates the results of the most recent Husserl research. It is divided into three parts, roughly following the chronological development of Husserl’s thought, from his early analyses of logic and intentionality, through his mature transcendental-philosophical analyses of reduction and constitution, to his late analyses of intersubjectivity and lifeworld. It can consequently serve as a concise and updated introduction to his thinking. (shrink)

By focusing on human virtues rather than the general morality of rational beings, Kant’s virtue theory presents systematic arguments from the perspectives of reason and experiential emotion, norms and disposition, spirituality and humanity, etc., which is of great significance to an overall understanding of Kantian ethics, thus clarifying misunderstandings from the past decades.

Marx's theory of alienation has some elements of an epistemology, but it is primarily a methodology. This is because alienation and the supersession of alienation are nothing but negation and a negation of the negation, a kind of historical dialectics. In using this methodology to analyze the contradictions between human existence and essence, Marx thoroughly exposed and criticized the callousness of relationships among humanity in capitalist society. On this basis, he considered socialist revolution and socialist production to be the means (...) for eliminating human alienation and for realizing human freedom, and thereby set forth an epistemology.

In the Economic and Philosophic Manuscripts of 1844, Marx commented that beauty is "the objectification of human essence.".

As all past philosophies superseded religion, their systems were established on the basis of comprehending a true human essence. As Marx pointed out, after first elaborating various concepts of religion, politics, morality, legal philosophy, and aesthetics, philosophers then kowtowed and became the slaves to those very concepts. Such a condition should be completely altered. From the time when Marx voiced these criticisms and placed "man" at the center of world history, while also pointing out that establishing the position of the (...) subject is proof of human freedom—that is, of human essence—and from the time when Marx emphasized that the real human world, including various social relations, ideological states, and the natural world "possessed by man," is the product of human creativity and a human manifestation formed in history and developed historically, and that man should and can emancipate himself from all that, all previous notions of the human essence became outdated and were no longer worth being seriously debated. From that time on, the philosophy of "man" has transcended the realm of speculative philosophy and gained unprecedented significance both in practice and in reality, and has become an active, initiating force in the modern socialist movement.
