企業倫理與組織承諾之關係-兼論異文化管理之干擾效果

為了解決Corporation vs compa的問題，作者張德慧 這樣論述：

本研究問題是探討企業倫理(business ethics)與組織承諾(organizational commitment)之關係，兼論異文化管理(cross-cultural management)之干擾效果，並比較荷日美三國在台灣子公司的差異。本研究透過郵寄問卷(questionnaires survey)的方式，邀請荷蘭、日本及美國在台灣子公司之企業高階主管填寫。總共寄發500份問卷，回收234份問卷，扣除無效問卷20份，有效問卷共有214份，有效回收率為42.8%。本研究發現：企業倫理落實程度與組織承諾成正向顯著關係；異文化管理制度對企業倫理與組織承諾之干擾影響獲得實證支持；荷日美在台

灣子公司在企業倫理落實程度、組織承諾與異文化管理制度程度的比較上，日本在台灣子公司的平均分數均高於美國與荷蘭在台灣的子公司。本研究建議多國籍企業應充分落實企業倫理，並透過第三文化管理來實施各項管理與福利等制度，能獲得員工的支持與和諧團結，進而提高員工組織承諾，創造卓越績效，以分享員工、股東、經營團隊及回饋社會，增益人民幸福。

印刷電路板級損耗傳輸線之眼圖分析與補償設計

為了解決Corporation vs compa的問題，作者郭維德 這樣論述：

As the speed of digital signal increases toward multi-gigabit range, many non-ideal effects, such as reflection noise, crosstalk noise, transmission-line losses, and simultaneous switching noise, previously regarded to be negligible in the design of system interconnect have become the critical desi

gn challenges for satisfying the requirements of signal integrity (SI), power integrity (PI), and electromagnetic interference (EMI). Among them, the significant one is the frequency-dependent transmission-line losses that mainly come from the finite conductivity of imperfect conductor and the natur

ally electric polarization of dielectric material. The thus induced dispersion will exhibit a relative long-tail response on the transmitted signal. In other words, the lossy lines may cause serious inter-symbol interference (ISI) problem, resulting in the occurrence of poor eye-diagram performance

or even the incorrect functionality of logic circuits, especially for the digital systems with the long-distance data transmission inside. In this thesis, a fast methodology that employs only two anti-polarity one-bit data patterns as input signal is first proposed to simulate the worst-case eye di

agram for the transmission- line system with a monotonic step response. Based on the assumption of a low-loss line, the impulse responses of lossy lines can be divided into three different mechanisms, which relate to the propagation delay, the conductive loss, and the dielectric loss, respectively.

To resolve the causality problem in the transient analyses, the Kramers-Kroning (K-K) relations are utilized to refine the deficiency regarding the derived impulse response for the dielectric loss. Two design graphs for the worst-case eye-diagram characteristics vs. An and Bn, the quantification fac

tors of conductive and dielectric losses, respectively, are constructed accordingly. Besides, the parametric analyses for the signal rising edges indicate that the effects of signal contents at the higher frequencies is negligible in the prediction of eye-opening profiles, while the unit interval in

the pulse train is critical. As for the specified eye mask, both design graphs can be used to evaluate the maximally usable length of lossy transmission lines and if a designed system is workable. Favorable agreements shown in the eye-diagram comparisons with the HSPICE simulation and measurement r

esults have validated the correctness and practicability of the present methodology. In order to compensate the eye-diagram performance degraded by the transmission-line losses, this thesis introduces two popular passive compensation schemes: one is the passive equalizer, and the other is the refle

ction gain induced by the insertion of the high-impedance element, i.e. inductance or high-impedance transmission line, into the load termination. The complete design methodologies for the two methods are well discussed. For the design of passive equalizer, a DC-level adapting method is proposed to

determine the optimum DC level of the equalized response. The high-pass response that requires to be realized by the passive equalizer can then be obtained. RLC equalizer circuit is first adopted to avoid violating the impedance matching condition. A design method has been established to convenient

ly extract the values of lumped components inside the one-stage RLC equalizer circuit. Multiple stages may be adopted, but the simulation result does not show any further enhancement on the eye quality. RL equalizer circuit is also applicable when the impedance matching situation is not a critical c

oncern. Good agreements between the simulations and measurements have verified the effectiveness of this compensation method. As for the design of high-impedance reflection gain, a systematic design methodology is proposed to resolve the optimal inductance or length of high-impedance line inserted

into the conventional matched termination for the finest compensation efficiency. A simple expression is derived to give the optimal inductance design, while the optimal length of high-impedance line can be estimated using a quasi-static equivalent circuit followed by a correction factor. In additio

n, two help graphs are constructed to evaluate the enhancement of maximally usable length for the PCB-scale microstrip transmission line with compensation. Some experiments are also performed to validate the proposed concept.
