The purpose of this paper is to investigate the impacts of investor attention on stock market activity.

The authors employed the Google Search Volume (GSV) Index, a direct and non-traditional proxy for investor attention.

The results indicate a strong correlation between GSV and trading volume – a traditional measure of attention – proving the new measure’s reliability. In addition, market-wide attention increases both stock illiquidity and volatility, whereas company-level attention shows mixed results, driving illiquidity and volatility in both directions.

To the best of the authors’ knowledge, Nguyen and Pham’s (2018) study has been the only previous study identifying investor attention in Vietnam by using GSV as a proxy and examining the impacts of broad search terms about the macroeconomy on the stock market as a whole – on stock indices’ movements. The paper will contribute to this by quantifying GSV impacts on each stock individually.

Although brand risk management (BRM) is widely acknowledged as critical concern of business leaders, there exists little empirical evidence regarding what activities firms could do to make their brand secured in the increasingly competitive market. Moreover, previous studies find out the important role of innovation stimulus in firm performance, but little attention is paid on how firm's innovation stimulates the firm's brand security. This study aims at exploring the impacts of BRM activities on brand security with the innovation stimulus as a moderator.

Mixed method is applied in conducting this research. In the qualitative research, an interview with managers of 20 large-size foodstuff companies in Vietnam is conducted to obtain insights into their understanding BRM activities and brand security as well as the role of innovation stimulus in managing brand risk and developing measurements for new constructs. In the quantitative research, a sample of 258 respondents is collected for the tests of reliability and validity as well as all hypotheses using SPSS software.

The authors’ findings show that the level of implementation of BRM activities influences the brand security with the moderating effect of innovation stimulus. Specifically, four dimensions of BRM activities including: strategy, personnel, processes and investment have direct, positive and significant impact on brand security. Innovation stimulus including innovation in leadership and innovation in knowledge management could serve as a moderating variable.

The findings of the current study have contributed to BRM literature by highlighting the importance of the implementation of BRM activities and the key role of innovation stimulus in ensuring the brand security, on which previous studies have paid little attention. The study suggests some guidance for firms about how to improve the innovation stimulus in enhancing the effectiveness of BRM activities and, as a result, increasing the brand security of the firm.

To study the situation of alcohol relapse and to investigate the relationship between psychological factors and alcohol relapse in persons with alcohol dependence in Thai Nguyen hospitals, Vietnam.

A correlation study was conducted among 110 patients. Data were collected through structured interviews and were analyzed using descriptive statistics and Spearman's correlation coefficient (r_s).

More than two-thirds of the participants were found to relapse more than once (X¯ = 2.04, SD = 0.86). Positive outcome expectancies, cravings, negative emotional states, and maladaptive coping were positively associated with relapse (r_s = 0.550, 0.522, 0.497; p = 0.000 and r_s = 0.217, p < 0.05, respectively). While, motivation to change with three subscales had a negative correlation to relapse including recognition (r_s = −0.199, p < 0.05), ambivalence (r_s = −0.331, p = 0.000), and taking steps (r_s = −0.606, p = 0.000). Adaptive coping, self-efficacy, and social support were also found to be negatively correlated to relapse (r_s = −0.535, −0.499, −0.338; p = 0.000, respectively). However, negative outcome expectancies (r_s = −0.024, p = 0.805) and positive emotional states (r_s = 0.081, p = 0.399) were not significantly related to relapse.

The findings of this study are significant implications for relapse prevention strategies. It suggests that the essential parts of relapse prevention are through: changing alcohol expectations, increase drinking refusal self-efficacy, coping skills training, enhancing motivation to change, managing alcohol craving and expanding social support.

This is the first study in Vietnam which investigated the relationship between psychological factors and alcohol relapse in individuals with alcohol dependence.
