Does Gender Influence Investment Choice? A Psychosomatic Study of GCC Entrepreneurs
Mohammed Abdul Imran KHAN,Syed Ahsan JAMIL,Shahebaz Sarfaraz KHAN,Meer Mazhar ALI 한국유통과학회 2022 The Journal of Asian Finance, Economics and Busine Vol.9 No.4
Entrepreneurs with behavioral finance biases are more likely to make irrational or financially detrimental decisions. Understanding financial behavior biases can assist in making sound financial decisions. Behavioral finance is a new topic that can assist researchers in better understanding investor behavior and preferences while purchasing and selling stocks. Using measures such as independent t-tests and average Likert five-point scale scores, this study seeks to determine how entrepreneurs make investment decisions and whether gender makes a difference. The study is empirical, and data from 1000 entrepreneurs were collected through convenience sampling. The study’s main findings show that there are numerous factors to consider while investing in stocks, including family planning, children’s education, investment security, and recurring income. Both men and women attempt to invest in many asset classes, but certain investments are extremely risky, while others are low risk. As a result, investors should assess risk based on their age and experience rather than their gender; this indicates that an investment in venture capital has nothing to do with gender but everything to do with the investor’s age.

Hydrogen gas and carbon nanotubes along with nanocarbon were produced from commercial natural gas using fixed bed catalyst reactor system. The maximum amount of carbon (491 g/g of catalyst) formation was achieved on 25% Ni, 3% Cu supported catalyst without formation of CO/CO2. Pure carbon nanotubes with length of 308 nm having balloon and horn type shapes were also formed at 673 K. Three sets of catalysts were prepared by varying the concentration of Ni in the first set, Cu concentration in the second set and doping with K in the third set to investigate the effect on stabilization of the catalyst and production of carbon nanotubes and hydrogen by copper and potassium doping. Particle size analysis revealed that most of the catalyst particles are in the range of 20-35 nm. All the catalysts were characterized using powder XRD, SEM/EDX, TPR, CHN, BET and CO-chemisorption. These studies indicate that surface geometry is modified electronically with the formation of different Ni, Cu and K phases, consequently, increasing the surface reactivity of the catalyst and in turn the Carbon nanotubes/H2 production. The addition of Cu and K enhances the catalyst dispersion with the increase in Ni loadings and maximum dispersion is achieved on 25% Ni: 3% Cu/Al catalyst. Clearly, the effect of particle size coupled with specific surface geometry on the production of hydrogen gas and carbon nanotubes prevails. Addition of K increases the catalyst stability with decrease in carbon formation, due to its interaction with Cu and Ni, masking Ni and Ni:Cu active sites.

Ternary selenide chalcogenide Tl3AsSe3 compound was identified as one of the most promising novel materials and potentially appropriate for multifunction applications. Current computational study is focused on computation of optical properties of Tl3AsX3 (X = S and Se) system where Modified Becke Johnson (mBJ) approximation is employed. The calculations of band structure revealed that both materials were indirect bandgap semiconducting materials with bandgap 1.5 eV and 1.9 eV respectively. The valence band maxima are mainly created because of Tl/As/S/Se(s/p/p/p) orbitals and conduction band is formed thanks to hybridizations of Tl/ As/S/Se(p) orbitals. The optical properties including complex dielectric function, reflectivity, energy loss function, refractive index, and real optical conductivity also calculated by using first-principles calculations. Our investigations explained that the two materials sustain their positive value of the refractive index and thus is the non-negative index of refractions, so these materials are active candidates for optoelectronic applications.
