Orchid abundance data collected over the past 30 years (1987–2016) from 440 sites within the National Orchid Monitoring Program were analyzed to quantify the population trends of orchids in Denmark, and the underlying reasons for the observed population trends were analyzed and discussed. Of the 45 monitored Danish orchids, 20 showed a significant decrease in abundance over the past 30 years (16, if only orchids with at least 50 observations each were selected), thus corroborating the previous observations of declining orchid abundances at the European scale. Generally, there was a significant negative effect of overgrowing with tall-growing herbs and shrubs on the abundance of Danish orchids, mainly caused by change of farming practices, as extensive management, such as grazing or mowing of light-open grassland areas, has decreased.

AbstractOrchid abundance data collected over the past 30 years (1987-2016) from 440 sites within the National Orchid Monitoring Program were analysed to quantify the population trends of orchids in Denmark, and the underlying reasons for the observed population trends were analysed and discussed. Twenty of the 45 monitored Danish orchids showed a significant decrease in abundance over the past 30 years (16, if only orchids with at least 50 observations each were selected), thus corroborating the previous observations of declining orchid abundances at European scale. Generally, there was a significant negative effect of overgrowing with tall-growing herbs and shrubs on the abundance of Danish orchids mainly caused by change of farming practises, as extensive management, such as grazing or mowing of light-open grassland areas, has decreased.

The botanical composition of grasslands determines the agronomic and natural values of swards. Good grassland management usually improves herbage value, but on the other hand it frequently decreases the plant diversity and species richness in the swards. In 1999 a field trial in a split-plot design with four replicates was therefore established on the Arrhenatherion type of vegetation in Ljubljana marsh meadows in order to investigate this relationship. Cutting regimes (2 cuts — with normal and delayed first cut, 3 cuts and 4 cuts per year) were allocated to the main plots and fertiliser treatments (zero fertiliser — control, PK and NPK with 2 or 3 N rates) were allocated to the sub-plots. The results at the 1 st cutting in the 5 th trial year were as follows: Fertilising either with PK or NPK had no significant negative effect on plant diversity in any of the cutting regimes. In most treatments the plant number even increased slightly compared to the control. On average, 20 species were listed on both unfertilised and fertilised swards. At this low to moderate level of exploitation intensity, the increased number of cuts had no significant negative effect on plant diversity either (19 species at 2 cuts vs. 20 species at 3 or 4 cuts). PK fertilisation increased the proportion of legumes in the herbage in the case of 2 or 3 cuts. The proportion of grasses in the herbage increased in all the fertilisation treatments with an increased numbers of cuts. Fertiliser treatment considerably reduced the proportion of marsh horsetail ( Equisetum palustre ) in the herbage of the meadows. This effect was even more pronounced at higher cut numbers. The proportion of Equisetum palustre in the herbage was the highest in the unfertilised sward with 2 cuts (26.4 %) and the lowest in the NPK-fertilised sward with 4 cuts (1.4%).

Experimental studies on the properties of cement paste and mortar with the use of limestone powder were carried out. The results show that the replacement with 10% to 30% limestone powder in cement paste can reduce the water requirement for certain flowability. As an inert material, the use of the limestone powder has significant negative effect on the mechanical properties of mortar. However, strength requirement of normal concrete (mortar) can be reached by reducing the water to cementious material ratio, which makes the use of limestone powder as a replacement of cement possible.

Dividend policy remains an important topic in modern corporate finance. Researchers, managers, and business owners seek to understand the optimal dividend policy. This study examined dividend policy as a driver of corporate growth in sub-Saharan Africa: evidence in Nigeria. The ex-post facto research design was adopted to analyse how dividend policy spur the growth of active insurance companies in the Nigerian Stock Exchange using secondary data of the sampled firms for 2007 – 2018 while utilising descriptive and inferential (regression) statistics in data analysis. The findings reveal that dividend policy in terms of dividend payout has an insignificant negative effect on corporate growth of insurance companies in Nigeria (?= -8.09E-05, p=0.77; Adjusted R2=0.4093; F(4,139)=3.29; p=0.00 with the controlling effect of efficiency, firm age and leverage which have a significant effect on corporate growth of insurance companies in Nigeria. Specifically, the study reveals that efficiency has a significant negative effect on corporate growth (?=-5.29, p<0.05); while firm age discloses a significant positive influence on corporate growth (?=0.417, p<0.05); as leverage exerts a significant negative effect on corporate growth (?=0.052, p<0.05). Therefore, the study concludes that dividend policy does not significantly drive insurance companies' dividend payout growth. The study recommends that insurance companies' management retain more of their profits, improve their efficiency, and control their leverage to further growth.

Causative Factors

In the Mississippi River Basin of North America, invasive bigheaded carp (silver carpHypophthalmichthys molitrixand bighead carpH. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities in this river are among the highest recorded on the continent. Understanding the causative factors behind erratic recruitment in this commercially-harvested invasive species is important for both limiting their spread and managing their harvest. We analyzed weekly catch records from 15 years of a standardized monitoring program to document the emergence of age-0 bigheaded carp in relation to environmental conditions. The appearance of age-0 fish was generally linked to hydrographic attributes, which probably serve as a cue for spawning. However, we found profound differences in the number of age-0 fish among years, which varied by as much as five orders of magnitude in successive years. The strong link between summer flooding and age-0 fish production we observed emphasizes the importance of understanding the hydrologic context in which sustained invasions occur. Despite evidence of sporadic recruitment, bigheaded carp populations in the Illinois River appear to be consistent or increasing because of particularly strong, episodic year classes.

Conventional banks are vulnerable to non-performing loans, because the credit is the main source income of a bank. Credit risk may still occur, even though the bank's management has made efforts based credit rating 5C. The purpose of this study was to determine how much influence the variable CAR, LAR, NIM, and ROE against Non-Performing Loans (NPL) in the banking companies listed on BEI. The sampling technique used is purposive sampling with criteria: (1) a conventional commercial bank listed on the BEI 2009-2013 period, (2) the bank that issued the annual financial statements in a row in the period from 2009 to 2013, and (3) bank which has a data completeness NPL, CAR, LAR, NIM, and ROE in the period 2009-2013. Data obtained from the annual report of each bank in 2009-2013. There are a total sample of 29 banks. The analysis technique used is multiple linear regression and hypothesis testing using t-statistic to test the partial regression coefficient and F-statistic to test the effect simultaneously with a significance level of 0.05. Before being tested by multiple linear regression, first performed classical assumption of normality test data. The results showed that there were no deviations from the classical assumption test. This indicates that the available data is normal or eligible to be used as a multiple linear regression model. From the analysis, CAR and ROE have significant negative effect on the NPL and LAR have not significant negative effect on the NPL, while variable NIM have significant positive effect on the NPL.

The article deals with the effect of culture on democracy. Cultural traditions, which had been developing for a long historical period, led to democracy in some societies. Modern American scientists divide the world in two types of societies: with the basic values of expression and values of surviving. Democracy wins in societies with the values of expression. So it is not enough to establish democratic laws by means of setting up a democracy. This is the reason why it doesn’t work in post-soviet countries. Ukraine has a wide experience of democracy in the past and the democratic values are the part of our national mentality. But this tradition was interrupted by 300 years of colonial dependence and 70 years of soviet totalitarianism. In such conditions the development of national culture will promote the democracy. On the other hand, we should understand the significance of personal culture of every member of society. Culture allows people to realize the importance of diversity, it makes a person more open and tolerant towards other groups in society and reinforces cohesion in society. Cultural participation, active or passive, has the great importance for democracy. It enables individuals to be more active and effective citizens. Governmental programs should promote cultural participation for people to make them more open, tolerant and respectful for other people’s values, to cultivate their strategy and critical thinking. In Ukraine, where the government is not always interested in the development of democracy, citizens should maintain cultural participation on their own by bringing up their children by means of different arts and involving them in different cultural events. The important part of cultural participation is cultural education. Unfortunately the policy of modern Ukraine tends to decrease cultural education and this situation has negative effect on building a democratic state.
