Cultural Values and Cross-cultural Video Consumption on YouTube

Video-sharing social media like YouTube provide access to diverse cultural products from all over the world, making it possible to test theories that the Web facilitates global cultural convergence. Drawing on a daily listing of YouTube's most popular videos across 58 countries, we investigate the consumption of popular videos in countries that differ in cultural values, language, gross domestic product, and Internet penetration rate. Although online social media facilitate global access to cultural products, we find this technological capability does not result in universal cultural convergence. Instead, consumption of popular videos in culturally different countries appears to be constrained by cultural values. Cross-cultural convergence is more advanced in cosmopolitan countries with cultural values that favor individualism and power inequality

Dynamic Yield Analysis and Enhancement of FPGA Reconfigurable Memory Systems

This paper addresses the issues of field programmable gate arrays (FPGA) reconfigurable memory systems with faulty physical memory cells and proposes yield measurement techniques. Static yield (i.e., the yield which does not take into account the inherited redundancy utilization for repair) and dynamic yield (i.e., the yield which takes into account the inherited redundancy utilization for repair) of FPGA reconfigurable memory systems and their characteristics are extensively analyzed. Yield enhancement of conventional memory systems relies on additional redundancy, but FPGA reconfigurable memory systems have inherited redundancy and customizability. Thus, they can accommodate numerous target memory configurations, and redundant memory cells, if any, can be used as spares to enhance the dynamic yield of a target memory configuration. Three fundamental strategies are introduced and analyzed; i.e., redundant bit utilization, redundant word utilization, and a combination of both. Mathematical analysis of those techniques also has been conducted to study their effects on the yield. Selecting the most yield enhancing logical memory configuration which can accommodate a target memory requirement among the candidate configurations is referred to as optimal fitting. Optimal fitting algorithms for single configuration fitting, sequential reconfiguration system fitting, and concurrent reconfiguration system fitting are investigated based on the proposed yield analysis techniques

Locally Synchronous, Globally Asynchronous Design for Quantum-Dot Cellular Automata (LSGA QCA)

The concept of clocking for QCA, referred to as the four-phase clocking, is widely used. However, inherited characteristics of QCA, such as the way to hold state, the way to synchronize data flows, and the way to power QCA cells, make the design of QCA circuits quite different from VLSI and introduce a variety of new design challenges and the most severe challenges are due to the fact that the overall timing of a QCA circuit is mainly dependent upon its layout. This fact is commonly referred to as the layout-timing problem. To circumvent the problem, a novel self-timed circuit design technique referred to as the Locally Synchronous, Globally Asynchronous Design for QCA is proposed in this paper. The proposed technique can significantly reduce the layout-timing dependency from the global network of QCA devices in a circuit; therefore, considerably flexible QCA circuit design will be possible

Teaching Nanotechnology by Introducing Crossbar-Based Architecture and Quantum-Dot Cellular Automata

The end of photolithography as the driver for Moore\u27s law is predicted within seven to twelve years and six different emerging technologies (mostly nanoscale) are expected to replace the current CMOS-based system integration paradigm. As nanotechnology is emerging, (1) there is a strong need for well-educated nanoscale systems engineers by industry, and (2) research and education efforts are also called to overcome numerous nanoscale systems issues. This paper is to propose a way to teach nanotechnology by introducing two emerging technologies: crossbar-based nanoarchitecture and quantum-dot cellular automata

Defect Characterization and Yield Analysis of Array-Based Nanoarchitecture

With molecular-scale materials and fabrication techniques recently developed, high-density computing systems in nanometer domain emerge. An array-based nanoarchitecture has been recently proposed based on nanowires such as carbon nanotubes (CNTs), silicon nanowires (SiNWs). High-density nanoarray-based systems consisting of nanometer-scale elements are likely to have many imperfections; thus, defect-tolerance is considered as one of the most significant challenges. In this paper, we propose a probabilistic yield model for the array-based nanoarchitecture. The proposed yield model can be used 1) to accurately estimate the raw and net array densities, and 2) to design and optimize more defect and fault-tolerant systems based on the array-based nanoarchitecture

Relations among education, religiosity and socioeconomic variables

This study demonstrates the relations of the position of education in the correlation between religiosity, and socioeconomic variables by using national-level, and large survey data. We used data from the international survey of 68 countries, and used statistical methods to create the composite scores of every variable. Next, we used Pearson and partial correlations to determine the significance of the relations between the three variables and path analysis to investigate the directions. The correlation coefficient between academic and religiosity variables was a significant and negatively high correlation; furthermore, the partial correlation was strong and significant when the socioeconomic variable was controlled. The correlation between religiosity and socioeconomic variables was a significant and negatively high correlation, and the partial correlation was not significant when the academic variable was controlled for. The correlation between academic and socioeconomic variables was a significant and positively high correlation, and the partial correlation was significant when the religious variable was controlled for. The path analysis reveals that the direction is as follows: socioeconomic, education, and finally, religiosity. Based on our results and the reviewed literature, this paper discusses how these results contribute to the secularization theory and how education mediates religiosity and socioeconomic variable.Keywords: education; international study; religiosity; socioeconomi
