Exchange trading rules, governance, and trading location of cross-listed stocks

We examine the location of trades for stocks cross-listed in the U.S. We consider for the first time in this context the role of the actual rules for trading on exchanges, both across countries and over time, to understand trading patterns. As well, we consider various new measures of sovereign governance and shareholder rights across counties to assess other legal and institutional drivers of trading activity. The data indicate that the proportion of trades that occurs on an exchange monotonically increases with sovereign governance and increases at a decreasing rate with the number of stock exchange trading rules

Act of Altruism in Nicola Davies’ Whale Boy

Eco-consciousness deals with the concern of human beings towards nature. Nature protects humans in all aspects unless they harm them. This act of selflessness is referred to as “altruism” in literature. Altruism is the literary term describing humanity or kindness. The kind behaviour of nature is characterised as a non-profitable aid to humans. There won't be any expectations, yet kindness will be expressed in a natural way. According to ethology, altruistic behaviour can be found in humans and animals. It is merely distinguished as a kinship between the two different groups. The novel Whale Boy deals with the behavioural attitudes of a whale and a boy. Nicola Davies, an English zoologist and author, described the kind behaviour of a wild creature towards humans. The novel centers on Michael Fontaine, a young boy who wants to go whale-watching and fishing in the deep ocean off the coast of his island. Nicola Davis focuses on marine wildlife and the issue of whaling and conservation. This article relates to the relationship between Michael and the whale. Thus, through the act of altruism, the article attempts to reflect the kinship between whales and humans

The pollen season dynamics and the relationship among some season parameters (start, end, annual total, season phases) in Kraków, Poland, 1991–2008

The dynamics of 15 taxa pollen seasons in Kraków, in 1991–2008 was monitored using a Burkard volumetric spore trap of the Hirst design. The highest daily pollen concentrations were achieved in the first half of May, and they were caused mainly by Betula and Pinus pollen. The second period of the high concentrations took place from the middle of July to the end of August (mainly Urtica pollen). Tree pollen seasons were shorter (18–24 days) in comparison with the most herbaceous pollen seasons (73–89 days), except at Artemisia and Ambrosia seasons (30 and 24 days, respectively). The season phases (percentyles) of the spring and late-summer taxa were the most variable in the consecutive years. The highest annual sums were noted for Urtica, Poaceae (herbaceous pollen seasons) and for Betula, Pinus, Alnus (tree pollen seasons), and the highest variability of annual totals was stated for Urtica, Populus, Fraxinus and the lowest for Ambrosia, Corylus, Poaceae. For the plants that pollinate in the middle of the pollen season (Quercus, Pinus and Rumex), the date of the season start seems not to be related to the season end, while for late pollen seasons, especially for Ambrosia and Artemisia, the statistically negative correlation between the start and the end season dates was found. Additionally, for the most studied taxa, the increase in annual pollen totals was observed. The presented results could be useful for the allergological practice and general botanical knowledge
