Published: February 2021

In the conditions of the Kirov region, the productivity of seeds of four complex hybrid populations (SGP) of red clover was studied, including those formed against an infectious fusarium background (SGPF). The research was carried out in the nursery for evaluating the seed productivity of 2017 sowing in comparison with the standard (st.) Dymkovsky for 2 years of use (y.u.). The characteristics of the SGP and SGPF according to winter hardiness, the start of vegetation phases of development, plant height, structure of seedgrass stand, yield and quality of seed material are given. All studied varieties were more productive than the standard (1.97 c/ha). Reliably high seed yield on average for 2 years was shown by SGPF-158-3 – 2.48 c/ha, SGP-188 – 2.32 c/ha, SGPF-157-3 – 2.16 c/ha. According to fruiting indicators, in 2019SGPF-158-3 with small heads, but with the largest number of flowers and seeds (132.2 and 77.4 pcs., respectively), good seediness (58.8 %) and high seed weight per head (0.153 g) was selected. Also, high rates were noted in the populations of SGPF-157-3 and SGPF-160-3. A strong correlation between seed yield and fruiting rates was revealed: the number of flowers in the head (r = 0.92), the total number of seeds in the head (r = 0.92), the number of filled seeds in the head (r = 0.94), the seediness of the head (r = 0.90), the total weight of seeds in the head (r = 0.85), the mass of filledseeds in the head (r = 0.87). A close positive correlation was noted between the hydrothermal coefficient (HTC) value and length (r = 0.86), width (r = 0.86) of the red clover head during the intergrowth period “regrowth - the beginning of flowering”. It has been established that the average daily air temperature and the sum of effective temperatures during the “beginning of flowering - ripening” period have a positive effect on the fruiting performance: “seediness of the heads” (r = 0.97 and r = 0.87) and “the number of seeds in the head” (r = 0.95 and r = 0.89, respectively). In the same interphase period, a close negative dependence of the indicated fruiting indices on the HTC values was revealed (r = -0.95 and r = -0.94). The sowing qualities of the seeds of the 2019 harvest were determined; it was found that all seed material corresponds to the category of “original and elite seeds”. As the result of the research, the populations of red clover SGPF-158-3, SGP-188 and SGPF-157-3, superior to st. Dymkovsky on seed productivity (by 0.51; 0.35 and 0.9 c/ha, respectively, LSD05 = 0.12 c/ha) and fruiting indicators, were selected.

Published: February 2021

The research contributes to provide insights on how characteristics of board of directors can affect firm value by analyzing board characteristics such as gender diversity, age and educational background to firm value of public firms in Indonesia. Generational diversity is being considered as an independent variable as it has never been assessed in Indonesia. Resource dependence theory and upper echelons theory are used in this research among other available concepts to explain the impact of board characteristics during the decision-making process and its access to resources. ROA is used in this research as the profitability approach indicator of firm value, while Tobin’s Q is used as the market approach indicator of firm value. Samples used in this research amounts to 1.151 samples from 411 companies. The results show that educational background and board age significantly affects firm value positively when measured by profitability approach indicator. While gender diversity and generational diversity both have no significant effect on firm value when measured by either profitability approach indicator or market approach indicator due to homogeneity. The results indicate that the appointment of directors with older age while possessing higher education can increase a company’s firm value which is measured by profitability indicators.

Published: February 2021

Assistant principals (APs) are important education personnel, but empirical evidence about their career outcomes remains scarce. Using administrative data from Tennessee and Missouri, we provide the first comprehensive analysis of AP mobility. While prior work focuses on promotions into principal positions, we also examine APs exiting school leadership and transferring across schools. We find yearly mobility rates of 25% to 28%, with 10% of APs leaving school leadership, 7.5% changing schools, and 7.5% to 10% becoming principals. We also document a strong relationship between AP mobility and principal turnover, where higher-performing APs are substantially more likely to replace their departing principal. Finally, principal transitions appear to increase the likelihood that APs exit school leadership and change schools.

The intended form of quality improvement is the formation of two-way communication or dialogue between the player and the audience. The player conveys the musical content of their interpretation of the work being played, while the audience responds to the standard measure of musical, visual and gestural norms that they have / believe in.

The species composition of the genus Linum L. section Adenolinum (Rchb.)Juz. was critically revised. The section comprises 28 species classified into 3 subsections (Longiunguiculata Svetlova, Amurense Svetlova and Breviunguiculata Svetlova), 4 series and 2 subseries. 3 new series (ser. Empetrifolia Naumenko-Svetlova, ser. Ovatosepala Naumenko-Svetlova and ser. Rotundatosepala Naumenko-Svetlova) and 2 new subseries (subser. Extraaxillaria (Optasyuk) Naumenko-Svetlova and subser. Perennia (Optasyuk) Naumenko-Svetlova) are described. One new combination in the rank of species (L. kurdicum (P. H. Davis) Naumenko-Svetlova) and two new combinations in the rank of subspecies (L. squamulosum Rudolphi subsp. tommasinii (Rchb.) Naumenko-Svetlova and L. squamulosum subsp. collinum (Boiss.) Naumenko-Svetlova) are published. It is shown that the species of the section subdivided into 3 groups according to traits of their sepals. Generally, most species within each subsection are characterized by a certain type of sepals. The most species of subsect.
