A New Distribution-Random Limit Normal Distribution
This paper introduces a new distribution to improve tail risk modeling. Based
on the classical normal distribution, we define a new distribution by a series
of heat equations. Then, we use market data to verify our model
Determinants of Job Turnover Intentions: Evidence from Singapore
This paper explores both observable and unobservable variables that would affect employed workersâ decisions on job change. We find that age, job satisfaction, satisfaction with working environment or job security, and firm size are among the major factors determining workersâ intentions of job-to-job mobility. Younger workers and workers in smaller firms are more likely to look for other jobs. We also find that men are more likely to consider a change in job than women, but when âactually looking for another jobâ is concerned, men and women do not differ. Furthermore, monthly income and working sector contribute significantly to looking for other jobs.Voluntary job-to-job mobility; Job satisfaction; Logistic regression model
Extended Quark Potential Model from Random Phase Approximation
The quark potential model is extended to include the sea quark excitation
using the random phase approximation (RPA). The effective quark interaction
preserves the important Quantum Chromodynamics (QCD) properties -- chiral
symmetry and confinement simultaneously. A primary qualitive analysis shows
that the meson as a well-known typical Goldstone boson and the other
mesons made up of valence quark pair such as the meson can
also be described in this extended quark potential model
