This study aims to analyze the ability to determine the weight of securities of stocks, bonds, mutual funds and deposits in the implementation of employer pension funds in Indonesia based on variables of asset allocation, portfolio turnover, board size, institutional ownership and diversification of the portfolio performance. The data collection method used was non-participant observation. By using a data pooling technique which combined time series data over period 2016-2018 and a cross section data of 64 Employer Pension Funds (DPPK, Employer Pension Funds), 192 observed analysis units were obtained. The effect of the variables was analyzed by using Structural Equation Modeling (path) as the analysis technique and using LISREL (Linear Structural Relationships) program. The test results showed that the asset allocation strategy had a positive effect on the investment portfolio performance. The same also happened to institutional ownership and diversification variables which also had a positive and significant effect on the investment portfolio performance. However, this study showed that there was no positive effect on the board size and portfolio turnover on the investment portfolio performance. Theoretical and managerial implications and also the limitations of this study are discussed at the end of this study.

This research is conducted to investigate determinants that affect delays in the signing of audit reports in Vietnam. The audit delay is measured as a function of the number of days that elapse from the accounting period until the date when the audit report is signed. This study employs a sample of 142 foreign direct investment (FDI) firms in Vietnam in 2019. We use Linear regression analysis, modelling audit delay as a function of the following explanatory variables: firm size, audit firm type, sign of income, audit opinion, and leverage. The findings indicate that the firms that report net income, that have standard audit opinion, and that have bigger size release their audited financial statements earlier. Variables such as auditor firm and leverage show no significant relationship with audit delay.

The firm's value becomes fundamental and important when it goes public which is a basis for investment decision. Intellectual capital as a spectrum of artificial intelligence capabilities helps us reveal patterns of big data in information-based historical data to do jobs faster and better with the help of technology. This research purposes to verify the model firm's value based on financial ratios, intellectual capital, and dividend policy. The populations in this research are on the automotive sub-sector companies and components that are listed in Indonesia Stock Exchange (IDX) over the period 2010-2019 and eleven companies met the requirements for sampling. Methods of data analysis is based on path analysis and Sobel test which comprise the classical assumptions test, linearity test, the total coefficient of determination and estimation, and hypothesis test through direct and indirect effect. The results of this research indicate that the firm's modeling value based on financial ratios, intellectual capital and dividend policy with outcome findings of financial ratio's viz. liquidity, solvency and profitability ratio did not significantly influence the dividend policy, while dividend policy had a significant influence on firm's value. Furthermore, financial ratios mediated by dividend policy were only influenced by solvency and profitability ratios while the liquidity ratios and intellectual capital factors were not significant effects.

This study employs a panel data analysis to identify the factors that significantly affect the capital adequacy ratio (CAR) of Vietnamese commercial banks for the period from 2011 to 2018. During this period, the number of banks had decreased from 41 to 31 due to mergers and acquisitions. The variables that are hypothesized to affect the capital adequacy ratio of commercial banks in Vietnam include bank size (SIZE), deposit (DEP), loan (LOA), loan loss reserves (LLR), liquidity (LIQ), return on assets (ROA), return on capital (ROE), net interest margin (NIM), non-performing loans (NPL) and leverage (LEV). The results indicate that LEV, LLR, ROE had a negative impact, ROA had a positive impact, and SIZE, DEP, LOA, LIQ, NIM, NPL did not significantly influence the CAR of Vietnamese commercial banks.

This paper investigates the effect of investments in subsidiaries, joint ventures and affiliates (affiliate investment) on firm growth. Using both static and dynamic panel data models with a sample dataset of 2,056 firm-year observations on Vietnam’s stock market from 2008-2015, the study finds that increasing affiliate investment in prior periods had a significantly positive impact on asset growth and net income growth (but not sales growth) of the firms in subsequent periods. In addition, the study finds new empirical evidence that private-controlled firms are more efficient than government-controlled firms in terms of affiliate investment. It is also found that profitability, government ownership and foreign ownership are significant dynamics for firm growth. This research sheds light on the role of affiliate investment as a corporate diversification strategy to boost firm growth, including growth rates of multinational corporations. It also provides important implications about the determinants of different dimensions of firm growth in the context of an Asian emerging economy.

Vietnam’s stock market although has small scale without a long history of development but the exchange has just started for a massive development. There have also been a number of anomalies, suggested that the market is not efficient. Therefore, there is a possibility that active investors with right strategy can consistently achieve higher profit than the market portfolio. This paper analyzes the statistical and economic significance of the calendar anomalies to propose appropriate strategies or recommendations. Studying the calendar anomalies in Vietnam also diversifies the research scope and validates some hypotheses in the past. In this research, the authors just analyze the monthly effects and the experimental results of this study may have significant implications not only for financial managers, financial advisers and investors but also for government to implement policy on stock market.

This study is an empirical research into the gap between disclosures in annual reports by listed companies and the needs of information by individual investors for investing decisions. The research uses some quantitative methods with the data collected from the annual reports of the top 30 non-financial listed companies having the high market capitalization and good liquidity on the Vietnam Stock Exchange. The authors compare 82 information disclosed by the corporates with the expectations of the investors by using SPSS 22. The results indicate that there is a discrepancy between the perception of individual investors and listed companies about the useful information in the corporate reports. In addition, both the mandatory and voluntary disclosures do not satisfy the requirements of the investors; however, the mandatory information is provided more than the voluntary one by the listed companies.

A novel one-pot, solvent-free method for the synthesis of dithiocarbamates was developed through the reaction of corresponding alkyl halides, amines and carbon disulfide employing catalytic amount of benzyl trimethyl ammonium hydroxide (Triton-B). The reaction conditions are milder with extremely simple work-up procedures than the reported methods, afforded high yields (82-98%) of the desired products.

Polyaniline (PANI) was synthesized chemically in an acidic medium in the presence of ammonium persulfate (APS) as an oxidizing agent. PANI/montmorillonite nano-composites were prepared in the presence of various amounts of modified clay (from 1 to 5 wt.%) by solution casting method. The free standing film of polyaniline and PANI/clay nano-composites was obtained by vaporization of solvent contain. Products were characterized by FT-IR spectra, SEM image, and XRD pattern. Thermal stability was also studied by TGA analysis, electrical conductivity was measured by four point probe technique and mechanical properties were studied by tensile strength. The PANI/clay nano-composites thermal and mechanical properties were observed to be remarkably improved. For example, polyaniline containing nano-clay has less weight loss compared to pure polyaniline. In addition Young’s modulus and strength at break point was increased in the case of polyaniline containing nano-clay The importance of our work is to provide a narrow look on the thermal and physical properties of polyaniline by the incorporation of montmorillonite into its structure as well as investigation of the conductivity of PANI/MMT nanocomposites as a potential conductive polymer to be used in solar cells or have corrosion protection applications.

The process described herein proceeds to obtaining diclofenac choline from choline bicarbonate and diclofenac acid in mild conditions, using non-toxic solvent, with the same impurity profile deriving from diclofenac particle as for diclofenac sodium EP. The substance is also substantially free from impurities deriving from choline and free from inorganic by-products, what means that the quality may be accepted for use as an active substance in medicine.
