Assessing the Effects of Responsible Leadership and Ethical Conflict on Behavioral Intention

[[abstract]]This study develops a research model that elaborates how responsible leadership and ethical conflict influence employees from the perspectives of role theory and attachment theory. Its empirical results reveal that turnover intention indirectly relates to ethical conflict and responsible leadership via the mediating mechanisms of organizational identification and organizational uncertainty. At the same time, helping intention indirectly relates to ethical conflict and responsible leadership only through organizational identification. Finally, the managerial implications for international business and research limitations based on the empirical results are discussed.[[notice]]補正完

Mood and the Market: Can Press Reports of Investors’ Mood Predict Stock Prices?

We examined whether press reports on the collective mood of investors can predict changes in stock prices. We collected data on the use of emotion words in newspaper reports on traders’ affect, coded these emotion words according to their location on an affective circumplex in terms of pleasantness and activation level, and created indices of collective mood for each trading day. Then, by using time series analyses, we examined whether these mood indices, depicting investors’ emotion on a given trading day, could predict the next day’s opening price of the stock market. The strongest findings showed that activated pleasant mood predicted increases in NASDAQ prices, while activated unpleasant mood predicted decreases in NASDAQ prices. We conclude that both valence and activation levels of collective mood are important in predicting trend continuation in stock prices

M-Ary Orthogonal Modulation For MC-CDMA Systems In Indoor Wireless Radio Networks

In this paper, we introduce the orthogonal M-ary Walsh modulation for multicarrier code-division-multiple-access (MC-CDMA) transmission. Analytical statements will be given for an AWGN channel and simulation results will be illustrated for a Rayleigh fading indoor channel assuming uplink transmission and coherent reception. Comparisons with antipodal modulation show that Walsh modulation performs better in terms of bit error rate and spectral efficiency. 1. INTRODUCTION In mobile radio communication systems, much attention has been paid to CDMA. One well-known scheme is the so-called Qualcomm system (IS-95) combining direct sequence CDMA (DS-CDMA) with M-ary orthogonal Walsh modulation. Results illustrated in [1] show the performance improvement of First International Workshop on MC-SS, April 1997, DLR, Oberpfaffenhofen, Germany 2 Walsh modulation over classical modulation schemes such as BPSK. Recently, MC-CDMA has been proposed combined with classical modulation [2, 3, 4, 5] and p..
