The Impact of CEO Characteristics on ESG and ESG Uncertainty
No full textThis study aims to explore the impact of CEO characteristics, CEO political inclination and corporate characteristics on ESG scores and ESG uncertainty, and further analyze the differences between different rating agencies.
The research covers American companies and CEOs from January 2002 to December 2021. The empirical results show that the higher ESG scores caused by higher compensation, younger, female gender, shorter tenure in the company, and higher total donations. Conversely, when the CEO pay is lower, the CEO is younger, has fewer years of employment, and the gender is a female CEO, the uncertainty of the company's ESG score increases.
The study also found that different rating agencies had different impacts on ratings. Variables such as CEO pay, political inclination, company returns, Tobin's Q, debt ratios, and industry concentration all affect the ratings to varying degrees. CEOs may pay more attention to the company's diversity development on ESG issues, and pay less attention to human rights issues. Therefore, companies may have different emphases and performances in different ESG aspects
Nanostructured SnO2/SnS Heterojunction Photocatalysts for CO2 conversion
No full textDue to the increased emission of carbon dioxide (CO2) in recent years,which is considered a harmful greenhouse gas,abnormal climate phenomena such as global warming,the greenhouse effect,rising temperatures,and sea-level rise have occurred,posing a threat to animal survival. Therefore,using photocatalysts to convert CO2 into methane,methanol,and other compounds not only helps reduce CO2 emissions but also generates renewable energy,meeting the demands of environmental protection and energy production.In this study, SnO2/SnS heterojunctions nanostructured photocatalysts were prepared using physical vapor deposition and GLAD (glancing angle deposition) coating techniques.The properties of the material and device,including their morphology,crystal structure,optical and electrical characteristics,work function,elemental composition,and CO2 conversion efficiency,were analyzed using SEM,XRD,UV-VIS,PL,EIS photocurrent measurements,UPS,XPS,and GC.
The CO2 conversion performance was found to be the highest for SnO2 annealed in air at 300 \uc2\ub0C for one hour, reaching 0.29805 \uce\ubcmol/cm2\uef\ubch.Furthermore,the deposition of SnS on SnO2 improved the light absorption and electron separation performance of the photocatalyst.The CO2 conversion performance increased under various annealing conditions,with the best performance observed for the heterojunction interface of SnO2 annealed at 300 \uc2\ub0C, achieving 0.40925\uce\ubcmol/cm2\uef\ubch
The Contribution of ESG in Stocks, Portfolios, Factors during the COVID-19 Crisis?
No full textThis paper analyzes the contributions of Environmental, Social, and Governance (ESG) to stocks, portfolios, and factors during the Covid-19 crisis. Previous literature has mainly focused on corporate social responsibility (CSR), while ESG provides a more comprehensive and effective way to measure the sustainability performance of companies. Most literature argues that CSR brings positive effects due to the benefits of maintaining good relationships with stakeholders. This paper presents the question of whether ESG contributes to maintaining relationships with stakeholders and delves into the contributions of ESG to stocks, portfolios, and factors during the Covid-19 crisis. The results show that: 1) companies with better CSR performance during a crisis period receive higher returns and have lower risks; 2) during a crisis, there are differences between portfolios with different levels of CSR performance. High ESG portfolios perform better; 3) in the crisis year, the effectiveness of ESG factor significantly increases, and models incorporating ESG factor exhibit better explanatory and predictive than models without it. In conclusion, this article encourages companies, investors, and investment institutions to actively engage in corporate social responsibility, quoting Aesop, "No act of kindness, no matter how small, is ever wasted.

Law and Regulations for Genetic Testing Under Comparative Law Research
No full textGenetic testing has its origins in the field of Genetics. It is a technique that combines knowledge from various fundamental sciences, predominantly biochemistry, molecular biology, and cellular biology. These tools were initially developed for research purposes within academia and later adopted by the medical field to enhance diagnosis and treatment methods. The advent of next-generation sequencing (NGS) significantly reduced the cost of genetic testing, paving the way for the emergence of precision medicine as a new field and industry. Notwithstanding, without proper respect for the research of the pure sciences and adequate oversight of genetic testing in Taiwan, it is hard to imagine a vigorous future for precision medicine to prosper. Hence, this study intends to amass previous accomplishments and information, to postulate favorable routes of reformation for future politicians and legislators.
The thesis begins with a preface that provides an introduction to the research background, purpose, and the materials and methods employed. The second chapter, titled "The Emergence of Genetic Testing and Its Application," delves into the complexity of defining genetic testing by exploring its origins and elucidating its current practices. The third chapter focuses on defining genetic testing based on previous literature and employing various categorizations to provide the general oversight of genetic testing. The fourth chapter compares the oversight of genetic testing in the United States and the European Union with the regulations in Taiwan. Finally, the fifth chapter draws the conclusions and suggestions derived from the research

Do managers exploit Non-GAAP earnings disclosure to meet or beat analyst forecasts? An analysis of REG SHO
No full textThe SEC introduced a pilot project (Reg-SHO), allowing capital market participants to short one-third of companies (pilot stocks) in the Russel 3000 index from 2005 to 2007. The study utilizes a quasi-natural Reg-SHO experiment to scrutinize the association between non-GAAP earnings and short-selling restrictions. Managers will more assembly employ non-GAAP earnings to practice opportunistic exclusion in recurring expenses in pilot stocks. Furthermore, for firms releasing short-selling restrictions, we uncover that managers will utilize non-GAAP earnings to meet or beat analysts' expectations and deliver worse future performance. Our research findings imply that within an environment devoid of short-selling restrictions, managers highly lean towards employing non-GAAP earnings to bolster company performance, thereby reducing the probability of short-selling activities
Searching for the Topological Phase of Zintl Materials via First-Principles Calculations Coupled with a High-Throughput Method
No full textTopological materials are well-known for being a good candidate for spintronics and electronic application due to their fascinating physical properties. Unlike conventional materials, topological materials have linear Dirac gapless conducting bands at the surface or edge of the crystal depending on the dimensionality. They are robust and not easily disrupted, and are protected by crystal symmetry or time-reversal symmetry. This results in a fascinating class of quantum materials that display unique electronic properties. Interestingly, a lot of thermoelectric materials are identified as topological materials since they have similar electronic properties. In fact, thermoelectric materials based on Zintl phase compounds, typically composed of an alkali or alkaline earth metal combined with a post-transition metal or a metalloid, have been found to exhibit unique structural, electronic, and topological properties. Here, we implemented first-principles calculation coupled with a high-throughput method to investigate the topological properties of the Zintl compounds and discovered a new topological Dirac semimetal. We focus on three-dimensional (3D) bulk Ca-based CaM2X2 (M = Cd or Zn, and X = N, P, As, Sb, or Bi) Zintl phase com- pounds with the CaAl2Si2-, ThCr2Si2-, and BaCu2S2-type crystal structures. Total ground state energy calculations showed that the favorable structure is the CaAl2Si2phase. Interestingly, we discovered that the CaCd2Bi2 is a new Dirac semimetal. Moreover, it is thermodynamically stable as confirmed by phonon calculation implying possible experimental synthesis. In addition to 3D materials, two-dimensional (2D) materials have also been found to exhibit non-trivial topological properties. In particular, transition metal dichalcogenides (TMDs) gain a lot of attention due to their intriguing electronic and topological properties and possible applications in electronic devices. Here, we theoretically and experimentally investigated the electronic band structure and topology on NiTe2 ultrathin films using first-principles calculations and angle-resolved photoemission spectroscopy (ARPES), respectively. Since NiTe2 was identified as type II Dirac semimetal in the bulk system, its corresponding ultrathin film structure was synthesized on BLG-SiC substrate using molecular beam epitaxy (MBE) to explore its 2D counterpart. Our theoretical results revealed the dimensionality crossover of NiTe2 from 1 to 5 tri-layers (TL) showing the topological states at an energy of \ue2\ubc -1.45 eV below the Fermi level and are in good agreement with the experimental findings. Finally, we investigated TMDs with transition metals from Group IV (Ti, Zr, and Hf), Group VI (Cr, Mo, and W), and Group X (Ni, Pd, and Pt) to elucidate their electronic, magnetic, and topological properties. Functionalization via absorption of hydrogen on one or two sides of these monolayer TMDs was also performed. The results showed monolayer TMDs structure phase transition and exhibited topological properties in some cases. Our findings provide significant contributions to the enhancement of our understanding of novel 3D and 2D materials for future technological applications
Innovative Rotor Structural Designs and Developments of High Power Density Permanent\ue2Magnet\ue2Assisted Synchronous Reluctance Motors
No full textBy inserting ferrite magnets into the rotor of a synchronous reluctance motor (SynRM), it is expected that the related operational performance of this motor can be improved. However, for those SynRMs with a higher number of poles, the rotor physical spaces for flux path adjustments and performance improvements are restricted. An assessment index is proposed to evaluate the volume of the optimal magnets based on the specified operational objectives and structural constraints, with the manufacturing convenience considered. In addition, to enhance the motor performance with more fluxes passing through the rotor available spaces by combining with the spoke-type NdFeB permanent magnets, a hybrid permanent-magnet-assisted SynRM structure is proposed
