    Abstract Using a sample of 248 firms on Hanoi and Ho Chi Minh City stock exchanges, we shows that education level and tenure of the CEOs do not have any impact on the performance of Vietnamese firms. However, when the CEOs hold the undergraduate degree, tenure has a positive impact on the performance of Vietnamese firms. Firms with female CEOs realize a significantly lower operation efficiency compared to that of firms with male CEOs. Moreover, splitting CEO and chairperson roles has a positive impact on the performance of Vietnamese firms.

    Abstract One popular approach to likelihood-free inference is the synthetic likelihood method, which assumes that some data summary statistics which are informative about model parameters are approximately Gaussian for each value of the parameter. Based on this assumption, a Gaussian likelihood can be constructed, where the mean and covariance matrix of the summary statistics are estimated via Monte Carlo. The objective of the current work is to improve on a variational implementation of the Bayesian synthetic likelihood introduced recently in the literature, to enable the application of that approach to high-dimensional problems. Here high-dimensional can mean problems with more than one hundred parameters. The improvements introduced relate to shrinkage estimation of covariance matrices in estimation of the synthetic likelihood, improved implementation of control variate approaches to stochastic gradient variance reduction, and parsimonious but expressive parametrizations of variational normal posterior covariance matrices in terms of factor structures to reduce the dimension of the optimization problem. The shrinkage covariance estimation is particularly important for stability of stochastic gradient optimization with noisy likelihood estimates. However, as the dimension increases, the quality of the posterior approximation deteriorates unless the number of Monte Carlo samples used to estimate the synthetic likelihood also increases. We explore the properties of the method in some real examples in cases where either the number of summary statistics, the number of model parameters, or both, are large.

    Abstract Three new flavonol glycosides, fissflavosides A-C (1–3), together with six known flavonol glycosides, kaempferol 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranoside (4), kaempferol 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-galactopyranoside (5), kaempferol 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (6), rhamnetin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (7), rutin (8), and isorhamnetin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranoside (9) were isolated from the methanol extract of the Fissistigma pallens leaves. Their chemical structures were determined by 1D-, 2D-NMR, and MS data as well as in comparison with reported data in the literature. Compounds 1–9 showed weak cytotoxic activity on three human cancer cell lines, HT-29, A-2058, A-549 with IC₅₀ ranging from 134.6 to 162.6 µM. In addition, the antioxidant capacities of compounds were also tested by ORAC assay. All compounds showed significant antioxidant with trolox equivalents ranging from 4.4 to 8.6 µM at the concentration of 1.0 µM. The results indicated 7 and 8 having meaningful reducing capacity of copper (I) ions of 2.7 to 6.9 µM at the concentrations of 1 and 2 µM.
