Item type:Item, Determinants of unpaid overtime: Exploring this phenomenon from the perspective of the embeddedness theory(2011-12-28) ;Tseng ;Fang-Tai ;經營管理研究所Institute of Business and ManagementThis paper attempts to be the pioneer literature review for unpaid overtime and further suggest an integrative framework for better understanding. The author begins the research with a simple question: is unpaid overtime an organizational driven behavior or a self-serving behavior? After reviewing the contradictory research results from Europe and Japan, the author applies the embeddedness theory to make up for the theoretical gaps and create twelve determinants to illustrate the complicated nature of unpaid overtime.Item type:Item, Evanescent-field optical amplifiers and lasers(2007-02-27) ;Chen ;Nan-Kuang ;Chi ;SienTsengAn optical amplifier and a laser generator based on the fiber side-polished technology having a high pumping efficiency, a low noise figure and a small footprint are provided in this application. The optical amplifier and the laser, which have a very long effective interaction length in conjunction with highly doped Erbium glass attached to its surface and an addition of a slanted fiber grating inscribed in the guiding core at the polished region can spatially separate the signal and pump power to simultaneously improve the pumping efficiency and optimize the penetrated depth of the signal evanescent-field. The spontaneous emission is kept from being amplified and therefore a high quality amplified signal is produced.Item type:Item, Evanescent-field optical amplifiers and lasers(2007-01-30) ;Chen ;Nan-Kuang ;Chi ;SienTsengAn optical amplifier and a laser generator based on the fiber side-polished technology, having a high pumping efficiency, a low noise figure and a small footprint are provided in this application.
