In this paper, two scaling matrices are used to research the synchronization of different dimensional chaotic systems with unknown parameters. Firstly, the definition of synchronization of chaotic systems with different dimensions is introduced. Secondly, based on Lyapunov stability theorem and adaptive control method, an adaptive feedback hybrid controller and parameter adaptive laws are designed to realize synchronization of uncertain chaotic systems with different dimensions. Finally, three numerical experiments are carried out to verify the effectiveness of the proposed method.

Most discussions of racial fetish center on the question of whether it is caused by negative racial stereotypes. In this paper I adopt a different strategy, one that begins with the experiences of those targeted by racial fetish rather than those who possess it; that is, I shift focus away from the origins of racial fetishes to their effects as a social phenomenon in a racially stratified world. I examine the case of preferences for Asian women, also known as ‘yellow (...) fever’, to argue against the claim that racial fetishes are unobjectionable if they are merely based on personal or aesthetic preference rather than racial stereotypes. I contend that even if this were so, yellow fever would still be morally objectionable because of the disproportionate psychological burdens it places on Asian and Asian-American women, along with the role it plays in a pernicious system of racial social meanings.

This chapter distinguishes between two concepts of moral responsibility. We are responsible for our actions in the first sense only when those actions reflect our identities as moral agents, i.e. when they are attributable to us. We are responsible in the second sense when it is appropriate for others to enforce certain expectations and demands on those actions, i.e. to hold us accountable for them. This distinction allows for an account of moral responsibility for implicit bias, defended here, on which (...) people may lack attributability for actions caused by implicit bias but are still accountable for them. What this amounts to is leaving aside appraisal-based forms of moral criticism such as blame and punishment in favor of non-appraising forms of accountability. This account not only does more justice to our moral experience and agency, but will also lead to more effective practices for combating the harms of implicit bias. (shrink)

No. 93: PAPELES SEMÁNTICOS Estudio de los papeles semánticos a partir de un enfoque tipológico, intentando unificar las distintas propuestas y analizar en profundidad el significado y la utilidad de esta etiqueta.

The object of this work is the interdisciplinary dialogue between natural sciences and Christian theology. The objective is to study the theological, epistemological and semantic conditions that make possible an articulation between scientific worldviews and theological discourses. In this study "to articulate" means that scientific theories and theological discourses do not share the same semantic horizon. At the same time, the verb "to articulate" implies that there is a possible mediation between scientific worldviews and systematic theology. The main thesis of (...) this study is that an articulation between scientific worldviews and systematic theology is possible through the mediation of philosophy. Natural sciences and philosophy refer to the order of manifestation where real things appear as phenomena. Christian theology refers to the order of revelation where God communicates Himself to the human person. The relationship between these two orders can be expressed with the maxim: neither confusion nor separation. Furthermore, there is a positive formulation of that relation: revelation assumes and transfigures what is manifested. This model of relation is the fundamental theological condition that makes possible an articulation between natural sciences and theology. In addition, there is an epistemological condition: the homologous rational structure of each rational field (sciences, philosophy and theology). Based on these theological and epistemological conditions, this research work proposes a theological method that articulates scientific worldviews into systematic theology through the mediation of philosophy. The method seeks two objectives: (a) that theology remains in ist epistemological boundaries and (b) to respect symmetrically the autonomy of natural sciences' procedures. Finally, the proposed method is applied to three examples: the elaboration of theological discourses, in dialogue with natural sciences, about (i) creation, (ii) human action and (iii) a spiritual contemplation of God's presence in the world. This research follows the contributions of two major scholars of the twentieth century: Jean Ladriere and Xavier Zubiri. Our considerations are based on the scholars' analyses of the plurality of epistemologies and their analyses of the intellectual act. (shrink)

The virtual brand community has become an important marketing tool for companies. A successful brand community marketing strategy should attract a large number of consumers. Although past studies have revealed consumer motivations for participating in virtual brand communities, they fail to answer an important question: Why is it so easy for some virtual brand communities to attract users while others have such difficulty? In this study, product characteristics are hypothesized to be important factors that determine consumer motivation to participate in (...) brand communities. Product characteristics can directly affect how actively consumers participate in brand communities. The results of questionnaires show that product complexity, product symbolism, and product satisfaction have a positive influence on consumers’ willingness to participate in brand communities. Notably, the duration of product use has a regulating effect on the influence of product satisfaction and product symbolism. A long period of product use weakens the influence of product satisfaction on consumers’ willingness to participate in brand communities. On the contrary, a long period of product use strengthens the influence of product symbolism on consumers’ willingness to participate in brand communities. This study enriches the literature on brand community participation and has implications for companies that aim to utilize brand communities for marketing. (shrink)
