How Does Social Media Affect Traditional Culture
In the 21st century, with the changes in mass media, new forms of social media have emerged. Social media has become an indispensable part of human society, thoroughly integrated into various aspects of peopleās lives. Social media plays an important role in the dissemination and promotion of traditional culture. However, in recent years, many new forms of social media have inappropriately used or showcased traditional culture and cultural heritage for the sake of entertainment, neglecting the respect for traditional culture and the understanding of its cultural essence, or directly engaging in cultural appropriation. This paper explores how to better use social media to promote and disseminate traditional culture through collecting and comparing the impact of social media on the dissemination of traditional culture, how to use social media in a correct manner
Evaluation of Wind Turbine Operation Status Based on ACO + FAHP
Aiming at the shortcomings of the fuzzy analytic hierarchy process (FAHP) in the comprehensive evaluation of wind power
projects, such as the diffi culty of satisfying and modifying the consistency of the judgment matrix and the high computational complexity, a
fuzzy analytic hierarchy process based on ant colony optimization (ACO+FAHP) is proposed. Firstly, the proposed fuzzy analytic hierarchy
process based on ant colony optimization algorithm overcomes the disadvantages that the weight and consistency cannot be improved once
the judgment matrix is given. The comparison chart of the consistency ratio calculated according to this method shows that the consistency
ratio B, C1-C5 all have diff erent degrees of reduction. Then, in view of the fact that various qualitative indicators cannot be accurately
calculated, the wind turbine operating status evaluation model is established by using the fuzzy comprehensive evaluation method. In this
paper, the evaluation score of a certain wind farm is 0.731, which means that the operators need to carry out high-level maintenance at this

Economic Consequences of an Enhanced Corporate Reporting Framework: The UK's move to Strategic Reporting
Demand for additional sustainability-related disclosures to complement current financial disclosures is growing. This thesis utilises the mandating of Strategic Reporting (SR) in the UK and proprietary data from PwC UK to study the impact of adopting an enhanced reporting framework that is aligned with the IR framework.
The first study finds a positive association between the disclosure quality of SR and capital-market benefits, including higher liquidity, lower cost of capital and more accurate, less dispersed analyst forecasts. Additionally, the effects of higher liquidity and lower cost of capital are more pronounced in the SR period compared to the previous reporting framework, suggesting SR enables more effective capital-market communication.
The second study examines the incremental economic impact of third-party assurance of non-financial information disclosed within SR. It finds that the provision of SR assurance is associated with more accurate and less dispersed analyst forecasts, suggesting that SR assurance acts as an effective credibility-enhancing mechanism for sophisticated capital-market participants.
Study Three provides a comparative analysis examining the Operating and Financial Review (OFR) produced by Australian listed companies. I find limited evidence that companies producing high-quality OFRs are associated with significant capital market outcomes. Australian companies are found to be lacking in disclosures in key areas central to an enhanced reporting framework, which could explain the limited capital-market benefits realised by Australian companies.
Study Four examines the association between SR quality and future stock price crash risk and finds that SR quality is negatively associated with future crash risk, which supports the view that high-quality SR improves transparency and curbs managerial bad news hoarding behaviour
Computing Ground State Properties with Early Fault-Tolerant Quantum Computers
Significant effort in applied quantum computing has been devoted to the
problem of ground state energy estimation for molecules and materials. Yet, for
many applications of practical value, additional properties of the ground state
must be estimated. These include Green's functions used to compute electron
transport in materials and the one-particle reduced density matrices used to
compute electric dipoles of molecules. In this paper, we propose a
quantum-classical hybrid algorithm to efficiently estimate such ground state
properties with high accuracy using low-depth quantum circuits. We provide an
analysis of various costs (circuit repetitions, maximal evolution time, and
expected total runtime) as a function of target accuracy, spectral gap, and
initial ground state overlap. This algorithm suggests a concrete approach to
using early fault tolerant quantum computers for carrying out industry-relevant
molecular and materials calculations

Quantitative Measurement of adhesion energy between nanolayers and substrates using a nanowire-supported bridging method
The measurement of adhesion energy between nanolayers and substrates holds
significant importance for the design, fabrication, and stability assessment of
micro-/nanoscale devices relying on nanolayers. In this study, we propose a
nanowire-supported bridging method based on an optical microscope-based
nanomanipulation technique to quantitatively measure the adhesion energy
between nanolayers and substrates. Using this innovative approach, we conducted
adhesion energy measurements between mica nanolayers and Si substrates,
revealing a value of approximately 110 J/m2. Additionally, we discuss the
applicable conditions of this new method. The proposed technique allows
measurements in atmospheric conditions and is, in principle, applicable to all
types of nanolayers and substrates. Consequently, it holds promise as a
universal method for assessing adhesion energy between nanolayers and
substrates, considering environmental factors such as atmosphere and roughness
