  • There have been many studies concerning the relationships between stock returns and volatilities. Their positive relationship is well known from the theoretical point of view, but not empirically shown. Franch, Schwert and Stambaugh [11] has empirically provided the indirect evidence of the positive relationship betwen expected stock return and expected volatility. However, their study lacks some statistical validity. This study reexamines the relationship using regression diagnostics and GARCH model from an international point of view. The empirical results fall to show the positive relationship between expected stock return and expected volaiility, which contradicts those of France, Schwert and Stambangh [1].

  • This study is intended to suggest fundamental data necessary for developing MBTI program that can help improve interpersonal relation skills of nursing science major students and their cohesion. This study is pre-experimental research by one group pretest-post test design to examine the effect of MBTI(Myers and Briggs Type Indicator) basic program on the interpersonal relationship between nursing science major students and their group cohesion and the relationship between interpersonal relationship and their group cohesion. I selected 39 of sophomore students in the department nursing science of K university in I metropolitan city as test group. 35 of them joined post-test. Pretest and MBTI basic program were done before conducting MBTI program. Collected data were analyzed by SPSS window 7.5. The difference in test group before and after conducting program was examined by paired t-test. The correlation between interpersonal relationship and group cohesion was measured by using Pearson Correlation Coefficient. The findings are as follows. $\cdot$ The difference before and after conducting MBTI program by sub-factors of interpersonal relation: There was no significant difference, as the average figure of interpersonal relation in test group was 87.22 before conducting MBTI and 85.08 after conducting MBTI respectively. The average figure of sensitivity among the sub-factors of interpersonal relation was 7.71 before conducting MBTI and reduced to 7.08 after conducting MBTI and there was significant difference between before and after conducting MBTI(t=-2.484, p=.018) $\cdot$ The difference in group cohesion before and after conducting MBTI program: The average figure of group cohesion in test group was 56.68 before conducting MBTI and increased a bit to 56.80 after conducting MBTI\, but there was no significant difference between them. $\cdot$ The relationship between interpersonal relationship and group cohesion before and after conducting MBTI: As the relationship between interpersonal relationship and group cohesion before and after conducting MBTI is examined, there was positive correlation of the significance level. p<.05 before conducting MBTI(r=.320, p=.047), and of the significance level, p<.01 after conducting MBTI(r=.780, p=.000). The investigation on the relation between sub-factors of group cohesion and of interpersonal relation before conducting MBTI basic program revealed that there was positive correlation between openness, reliability, friendliness and satisfaction, and group intervention, between receptivity among group members and reliability, and between group atmosphere and satisfaction. The investigation on the relation between sub-factors of group cohesion and of interpersonal relation after conducting MBTI basic program revealed that there was positive correlation between openness, communication, understanding, friendliness and satisfaction. and group intervention. There was positive correlation between receptivity among group members and openness, communication, understanding, friendliness and satisfaction. There was positive correlation between openness, communication, friendliness and satisfaction, and group atmosphere. Based on the above findings, I realize that MBTI basic program is essential to the improvement of group cohesion. In addition, it is shown that the sub-factors of interpersonal relation such as openness, communication, friendliness, satisfaction, and understanding, and the sub-factors such as group intervention and receptivity among group members are major factors to improve interpersonal relationship and group cohesion. So, the future MBTI program should include sub-programs that deal with the above factors to improve interpersonal relationship and group cohesion.

  • Although recent reports suggest that the negative correlation between the Arctic Oscillation (AO) and the East Asian winter monsoon (EAWM) has been strengthened, it is not clear whether this intermittent relationship is an intrinsic oscillation in the climate system. We investigate the oscillating behavior of the AO-EAWM relationship at decadal time scales using the long-term (500-yr) climate model simulation. The results show that ice cover over the East Siberian Seas is responsible for the change in the coupling strength between AO and EAWM. We found that increased ice cover over these seas strengthens the AO-EAWM linkage, subsequently enhancing cold advection over the East Asia due to anomalous northerly flow via a weakened jet stream. Thus, this strengthened relationship favors more frequent occurrences of cold surges in the EAWM region. Results also indicate that the oscillating relationship between AO and EAWM is a natural variability without anthropogenic drivers, which may help us understand the AO-EAWM linkage under climate change.

  • This paper reviewed the relationship between job characteristics and job stress responses(physiological response, psychological response, behavioral response), and the moderating effect of social support. Based on the responses from 187 employees in small & medium manufacturing industry, hierarchical regressional analysis showed that job characteristics factors have partly negative relationships with job stress response. But, job variety has positive relationship. Social support has partly moderating effect on the relationship between job characteristics and job stress.

  • This study aims to examine the relationship between corporate social responsibility (CSR) expenditures and both financial and non-financial performance of Jordanian commercial banks during the period 2008-2018. To measure the variables of interest, secondary data published on Amman Stock Exchange (ASE) website were processed to become preliminary data suitable for the nature of the study. The study sample amounted to 13 commercial banks, which represent all Jordanian commercial banks listed on ASE.. The study found that there is a positive, statistically significant relationship between CSR expenditures and financial performance, as the study showed that the return on equity (ROE) has a positive and significant relationship with CSR expenditure, while the return on assets (ROA) and Tobin's Q model have a statistically significant negative relationship with CSR expenditure, while the market stock price (MSP) had a positive, but not statistically significant. The study also found that there is a positive, statistically significant relationship between CSR expenditures and non-financial performance, which was represented by total deposits and total training expenditures in Jordanian commercial banks. Accordingly, the study recommends encouraging banks to prepare sustainability reports and CSR reports, which are considered comprehensive, and not only with disclosures within the annual reports.

  • This study develops a contingency fit between client IT capability and vendor competence in IS outsourcing relationship by integrating both the contingency theory in organization and the relationship theory in IS outsourcing. By adopting a fit as a moderation, the relationship intensity of IS outsourcing is hypothesized to be influenced by the fit between client IT capability and vendor competence, thereby leading to the success of outsourcing. The testing data was obtained from 20 IS outsourcing projects from both clients and vendors in Korea. The research model proposed in this study was then tested using the structural equation model (SEM). As expected, the result shows that when there is a fit between client IT capability and vendor competence, higher level of relationship intensity and outsourcing success exhibits. The findings have significant impactions for further research and practice.
