The Relationship

Using a resource-based view and dynamic capabilities approach, this study investigates both the internal and external factors influencing competitive advantage in the hotel industry. For this purpose, we examine how organizational capabilities may lead to customer relationship building and in turn to competitive advantage. We further test the moderation role of market dynamism on the relationship between organizational capabilities and customer relationship building, and also investigate the mediation effect of customer relationship building on the association between organizational capabilities and competitive advantage. A questionnaire-based study was conducted among hotel employees in Northern Cyprus to test the conceptual model. A set of approaches was applied to detect common method bias and test the validity and reliability of the questionnaire. Correlation and regression analyses were conducted to evaluate the relationships between the variables, and bootstrapping analysis was applied to assess the mediation and moderation effects. The results revealed that organizational capabilities enhance customer relationship building and competitive advantage. Market dynamism as an external factor moderates the relationship between organizational capabilities and customer relationship building. There is also an indirect association between organizational capabilities and competitive advantage through the mediation of customer relationship building. The theoretical and practical implications of the findings are discussed.

The multilevel per cell technology and continued scaling down process technology significantly improves the storage density of NAND flash memory but also brings about a challenge in that data reliability degrades due to the serious noise. To ensure the data reliability, many noise mitigation technologies have been proposed. However, they only mitigate one of the noises of the NAND flash memory channel. In this paper, we consider all the main noises and present a novel neural network-assisted error correction (ANNAEC) scheme to increase the reliability of multi-level cell (MLC) NAND flash memory. To avoid using retention time as an input parameter of the neural network, we propose a relative log-likelihood ratio (LLR) to estimate the actual LLR. Then, we transform the bit detection into a clustering problem and propose to employ a neural network to learn the error characteristics of the NAND flash memory channel. Therefore, the trained neural network has optimized performances of bit error detection. Simulation results show that our proposed scheme can significantly improve the performance of the bit error detection and increase the endurance of NAND flash memory.

The Relationship

Living in a world where we can expand our economic wealth and the richness of human life is the core of the human development concept. Greater well-being for all can be achieved by improving people’s capabilities and more importantly, by giving individuals the ability to use their knowledge and skills. The economic complexity index (i.e., ECI) is a new indicator that defines a country’s complexity. Through a vast network, citizens can transfer an enormous quantity of relevant knowledge, leading to the creation of diversified and complex products. However, the relationship between economic complexity and human development is not that simple. Thus, this paper aimed to understand it deeper—international migration and logistics performance are used as moderators. Hierarchical linear modeling was the statistical tool used to analyze two groups of countries from 1990 to 2017. For robustness and to deal with possible endogeneity issues, different year lags were also included. The results show that international migration and logistics performance are decisive moderators as they change the relationship between economic complexity and human development.

AbstractRealizing the potential of quantum computing requires sufficiently low logical error rates1. Many applications call for error rates as low as 10−15 (refs. 2–9), but state-of-the-art quantum platforms typically have physical error rates near 10−3 (refs. 10–14). Quantum error correction15–17 promises to bridge this divide by distributing quantum logical information across many physical qubits in such a way that errors can be detected and corrected. Errors on the encoded logical qubit state can be exponentially suppressed as the number of physical qubits grows, provided that the physical error rates are below a certain threshold and stable over the course of a computation. Here we implement one-dimensional repetition codes embedded in a two-dimensional grid of superconducting qubits that demonstrate exponential suppression of bit-flip or phase-flip errors, reducing logical error per round more than 100-fold when increasing the number of qubits from 5 to 21. Crucially, this error suppression is stable over 50 rounds of error correction. We also introduce a method for analysing error correlations with high precision, allowing us to characterize error locality while performing quantum error correction. Finally, we perform error detection with a small logical qubit using the 2D surface code on the same device18,19 and show that the results from both one- and two-dimensional codes agree with numerical simulations that use a simple depolarizing error model. These experimental demonstrations provide a foundation for building a scalable fault-tolerant quantum computer with superconducting qubits.

The Relationship

<p>The current study examined the relationship between university students’ academic identity and their perceptions of their parents’ parenting styles among a sample of Omani students. Marcia’s (1993) academic identity statuses are adapted. These are moratorium, foreclosed, diffuse, and achievement. Parenting styles included authoritative, authoritarian, and permissive. The participants were 192 undergraduate students from Oman. The participants responded to Arabic versions of the Academic Identity Status (Was &amp; Isaacson, 2008) and the Parenting Authority Questionnaire (Buri, 1991). Both questionnaires showed reasonable evidence of validity and reliability. The findings show that parenting styles varied in their relationship with the four statuses of students’ academic identity. Using the three parenting styles as predictors in the regression models, the lowest percentage of explained variance among identity dimensions was found for moratorium, while the highest explained variance was found for diffusion. Implications and future research are discussed and presented by the end of the paper.</p>
