Inverted Index Compression Using Word-Aligned Binary Codes   总被引：3，自引：1，他引：3  

Vo Ngoc Anh  Alistair Moffat 《Information Retrieval》2005,8(1):151-166

We examine index representation techniques for document-based inverted files, and present a mechanism for compressing them using word-aligned binary codes. The new approach allows extremely fast decoding of inverted lists during query processing, while providing compression rates better than other high-throughput representations. Results are given for several large text collections in support of these claims, both for compression effectiveness and query efficiency.  相似文献

Is Transracial the Same as Transgender? The Utility and Limitations of Identity Analogies in Multicultural Education     

Vu T. Tran  Marc P. Johnston-Guerrero 《Multicultural Perspectives》2016,18(3):134-139

In June 2015, Melissa Harris-Perry infamously analogized the possibility of trans-Black identity to the reality of transgender identity. Such analogies happen often and are used mostly for the benefit of learning about a less familiar form of identity. Building from a recent article by Suthakaranm, Filsinger, and White (2013 Suthakaran, V., Filsinger, K., &; White, B. (2013). Using analogies as an experiential learning technique in multicultural education. Multicultural Perspectives, 15(2), 92–97.[Taylor &; Francis Online] , [Google Scholar]) that presented a compelling argument for the use of analogies as an experiential learning tool in multicultural education, we advance the conversation by distinguishing a particular form of analogies: identity analogies. We explore the benefits and challenges of utilizing identity analogies as a tool for multicultural educators within U.S. higher education.  相似文献   

Robotic automation of droplet microfluidics     

Tuan M. Tran  Samuel C. Kim  Cyrus Modavi  Adam R. Abate 《Biomicrofluidics》2022,16(1)

Droplet microfluidics enables powerful analytic capabilities but often requires workflows involving macro- and microfluidic processing steps that are cumbersome to perform manually. Here, we demonstrate the automation of droplet microfluidics with commercial fluid-handling robotics. The workflows incorporate common microfluidic devices including droplet generators, mergers, and sorters and utilize the robot''s native capabilities for thermal control, incubation, and plate scanning. The ability to automate microfluidic devices using commercial fluid handling will speed up the integration of these methods into biological workflows.  相似文献

Is graduate employability the ‘whole-of-higher-education-issue’?     

Thi Tuyet Tran 《Journal of Education & Work》2015,28(3):207-227

Graduate employability has become an issue in Vietnam since many university students do not satisfy the needs of employers. Universities often receive the strongest criticism on the poor employability assets graduates possess. The ill-preparation of university graduates is considered the result of the out dated and irrelevant curriculum in the higher education system, of the traditional teaching methods and the absent of career guidance in most universities. This article, however, aims to challenge this common criticism that university is to blame for the ill-preparation for employment of its graduates. By conducting a qualitative research inviting the voices of both students and employers on the issue, this article wants to address a wider context and circumstance and also the related issues surrounding the transition from university to work of Vietnamese university graduates. It suggests that not only universities, but also students, employers and other related stakeholders (i.e. student’s family, government and educational policy makers) should acknowledge the changes in society, should be aware of the cultural features at work, and should see their responsibility in the process. They all should make an effort to create mutual understanding, to collaborate and to enhance the development of graduate employability in the Vietnamese context.  相似文献   

Vygotsky’s sociocultural theory in the context of globalization     

Simon Marginson  Thi Kim Anh Dang 《Asia Pacific Journal of Education》2017,37(1):116-129

The article reviews the social-educational theorization of the early Soviet psychologist L. S. Vygotsky (1896–1934) in the light of the impact of communicative globalization in educational practice. Vygotsky proposed four “genetic domains” for investigating higher cognitive processes: the phylogenetic (humans undergoing natural evolution), the cultural-historical (social activity of humans), the ontogenetic (individual lifespan), and the microgenetic (immediate events). Vygotskian sociocultural theory is widely used in educational research, especially Vygotsky’s notion of mediated development via tools and signs. Since Vygotsky, communicative globalization has transformed educational potentials. Nevertheless, provided adjustments are made to Vygotsky’s genetic method to incorporate time-space compression, the mutual presence of the genetic domains, and the glonacal heuristic, Vygotskian theory continues to be useful in socially-situated investigations of educational development and transformation, and opens another way into the global, for example investigation of the role of global mediation in learning.  相似文献   

Electrical lysis of cells for detergent-free droplet assays     

N. de Lange  T. M. Tran  A. R. Abate 《Biomicrofluidics》2016,10(2)

Efficient lysis is critical when analyzing single cells in microfluidic droplets, but existing methods utilize detergents that can interfere with the assays to be performed. We demonstrate robust cell lysis without the use of detergents or other chemicals. In our method, cells are exposed to electric field immediately before encapsulation in droplets, resulting in cell lysis. We characterize lysis efficiency as a function of control parameters and demonstrate compatibility with enzymatic assays by measuring the catalysis of β-glucosidase, an important cellulase used in the conversion of biomass to biofuel. Our method enables assays in microfluidic droplets that are incompatible with detergents.  相似文献
