Abstract:

The principal ingredient of an optical fiber is quartz glass. The quality of the optical fiber decreases if impure foreign substances are attached to its preform surface. If residual strain inside a preform is significant, it cracks with a small impact during drawing or transporting. Furthermore, damages and unevenness on the surface of an optical fiber base material break the fiber during drawing. The present work signifies that chlorine pre-treatment enhances mechanical properties of the optical fiber glass. FTIR (Fourier-Transform Infrared Spectroscopy) results show that chlorine gas chemically modifies the structure of silica clad; chlorine is known to soften glass. Metallic impurities on the preform surface likely formed volatile metal chlorides due to chlorine pretreatment at elevated temperature. The chlorine also acts as a drying agent, and therefore the preform surface is anticipated to be water deficient and supposedly avoids particle adhesion on the glass surface. The Weibull analysis of long length tensile strength demarcates a substantial shift in its knee. The higher dynamic fatigue n-value also indicated surface crack healing.

Abstract:

All of us know what it is like to experience humor. Humor and laughter are universal aspects of human experience, occurring in all cultures and virtually in all individuals throughout the world. For people today, the workplace is associated more with the cubicles they sit, than with the co-workers around them. With reference to the current generation and the work context, the paper aims to understand the concept of humor at the workplace and its influence on team creativity in organizations. Humor is a multi-disciplinary topic that has been investigated for many years by researchers from fields such as anthropology, psychology, physiology and linguistics but significantly less thoroughly by management researchers. Researchers in the field of creativity also had their initial focus on the individual differences leading to creativity. Although the studies yielded some important findings regarding creative people, it provided the little help to practitioners in helping people develop creativity and almost ignored the role of social environment in enhancing creativity. After a review the relevant literature of the key variables, a theoretical framework is proposed linking workplace humor, emotional contagion, and team creativity. The findings of the study are expected to help academicians gain clarity on Workplace Humor for future research.
