Using postcolonial and decolonial theory as a framework, this study focuses on the lived experiences of international students of color entering the United States for the first time in their lives from the global South. Our goal was to understand how they communicate/perform their dis/located identities in relation to “race” when immersed for the first time in a White settler society context. Findings from this qualitative study underscore discomfort with U.S.-centric race logics, production of ambiguity in relation to identity and race, and the growth of compassion for cultural Others as a result of becoming racial Other. The decolonial implications of such dis-identification with U.S. colonial race categories are discussed. 相似文献

In this hyper-competitive era, patents are an essential input to realizing sustainable competitive advantage. However, individual differences exist in patenting filing behavior and behaviors related to commercialization of patents. This study explores these behaviors in the context of three demographic variables. The demographic variables are patenting and commercialization experiences of inventors, age and sector. Further, aspirations of these inventors are assessed using external motivators of wealth, fame, and concern for societal welfare, and internal motivators such as pragmatism. The findings of this empirical study (n = 116) suggest that sector and age determine differences in personal internal motivators more than patent commercialization experience. Implications of the study are discussed. 相似文献

With the fast development of acoustic systems in clinical and therapeutic applications, acoustically driven microbubbles have gained a prominent role as powerful tools to carry, transfer, direct, and target drug molecules in cells, tissues, and tumors in the expanding fields of targeted drug delivery and gene therapy. The aim of the present study is to establish a biocompatible acoustic microfluidic system and to demonstrate the generation of an acoustic field and its effects on microbubbles and biological cells in the microfluidic system. The acoustic field creates non-linear oscillations of the microbubble-clusters, which results in generation of shear stress on cells in such microsystems. This effectively helps in delivering extracellular probes in living cells by sonoporation. The sonoporation is investigated under the combined effects of acoustic stress and hydrodynamic stress during targeted drug and gene delivery. 相似文献

Gender bias exists in our language environment. We investigated personal name usage in two large corpora of language written for and by U.K. children aged 5–13. Study 1 found an overrepresentation of male names in children’s books, largely attributable to male authors. In stories written by over 100,000 children, Study 2 found an overall male bias that interacted with age. Younger children wrote more about their own gender. With age, girls became more balanced yet boys continued to show a strong male bias. Our findings demonstrate a male-centered bias in both children’s books and their own writing. We consider the power of written language to both shape and be shaped by cultural stereotypes via systematic biases in gender associations. 相似文献

This paper addresses a finite-time rendezvous problem for a group of unmanned aerial vehicles (UAVs), in the absence of a leader or a reference trajectory. When the UAVs do not cooperate, they are assumed to use Nash equilibrium strategies (NES). However, when the UAVs can communicate among themselves, they can implement cooperative game theoretic strategies for mutual benefit. In a convex linear quadratic differential game (LQDG), a Pareto-optimal solution (POS) is obtained when the UAVs jointly minimize a team cost functional, which is constructed through a convex combination of individual cost functionals. This paper proposes an algorithm to determine the convex combination of weights corresponding to the Pareto-optimal Nash Bargaining Solution (NBS), which offers each UAV a lower cost than that incurred from the NES. Conditions on the cost functions that make the proposed algorithm converge to the NBS are presented. A UAV, programmed to choose its strategies at a given time based upon cost-to-go estimates for the rest of the game duration, may switch to NES finding it to be more beneficial than continuing with a cooperative strategy it previously agreed upon with the other UAVs. For such scenarios, a renegotiation method, that makes use of the proposed algorithm to obtain the NBS corresponding to the state of the game at an intermediate time, is proposed. This renegotiation method helps to establish cooperation between UAVs and prevents non-cooperative behaviour. In this context, the conditions of time consistency of a cooperative solution have been derived in connection to LQDG. The efficacy of the guidance law derived from the proposed algorithm is illustrated through simulations. 相似文献

Majority of consumer durables have multiple technological generations. Each succeeding generation offers some innovative performance enhancements, feature additions etc. distinguishing itself from the past releases. Therefore the consumer's attitude towards each of them can be very different. There is a need to understand consumer psychology and have accurate measure to predict the adoption process of new technology. Mathematical models have proved to be ideal tools to explain the past purchasing-behavior and also for forecasting. This paper focuses on studying the relative changes of diffusion parameters for both first time purchasers and upgraders along with developing a more general sales model for multiple technology generation products. The proposed model explicitly identifies different groups of purchaser viz. first timers and repeaters (upgraders). 相似文献
