Zde a nyní / Here and Now

Chlastáková, Barbora January 2012 (has links)
Here and now In my painting series „Here and now“ I use a method of permeating, come up and lose the object. My paintings moves from concrete visual to abstract position. In this form I have found my one way to express term whitch I called „folklore abstract“. Each pice consist „things“ from my grandmothers house, with whitch I have got some relationship. I have create three large 200x190, 190x180, 190x180 oil paintings.

The neural correlates of exploration

Hassall, Cameron Dale 28 August 2019 (has links)
Like other animals, humans explore to learn about the world, and exploit what we have learned in order to maximize reward. The trade-off between exploration and exploitation is a widely-studied topic that cuts across multiple domains, including animal ecology, economics, and computer science. This work approaches the explore-exploit dilemma from the perspective of cognitive neuroscience. In particular, how are our decisions to explore or exploit represented computationally? And how is that representation implemented in the brain? Experiment 1 examined neural signals following outcomes in a risk-taking task. Explorations – defined as slower responses – were preceded by an enhancement of the P300, a component of the human event-related brain potential thought to reflect a phasic release of norepinephrine from locus coeruleus. Experiment 2 revealed that the same neural signal precedes feedback in a learning task called a two-armed bandit. There, a reinforcement learning model was used to classify responses as either exploitations or explorations; exploitations were driven by previous rewards, and explorations were not. Experiments 3 and 4 extended these results in three important ways. First, evidence is presented that the neural signal observed in Experiments 1 and 2 was driven not only by the upcoming decision, but also by the preceding decision (perhaps even more so). Second, Experiments 3 and 4 involved increasingly larger action spaces. Experiment 3 involved choosing from among either 4, 9, or 16 options. Experiment 4 involved searching for rewards in continuous two-dimensional map. In both experiments, the feedback-locked P300 was enhanced following exploration. Third, exploitation was the more common strategy in Experiments 1 and 2. Thus, it was unclear whether the exploration-related P300 enhancement observed there was due to exploration per se, to exploration rate, or to the fact that exploration was rare compared to exploitation. Experiment 3 partially address this by eliciting different rates of exploration; the exploration-related P300 effect correlated with rate of exploration. In Experiment 4, exploration was more common than exploitation (in contrast to Experiments 1–3); even so, exploration was followed by a P300 enhancement. Together, Experiments 1–4 suggest the presence of a general neural system related to exploration that operates across multiple task types (discrete to continuous), regardless of whether exploration or exploitation is the more common task strategy. The proposed purpose of this neural signal is to interrupt one mode of decision-making (exploration) in favour of another (exploitation). / Graduate

Vliv konfuciánství na obchod v Asii / Influence of Confucianism on business in Asia

Duong, Minh Vuong January 2010 (has links)
World's largest business center is now located in East Asia, which is also the place of Confucian origin..Asian cultures influenced by Confucianism are known for their "inner strength" and stability. Trade in these countries flourishes as nowhere else in the world. The way of life and perception of social values, according to Confucian values significantly affected the business culture of these countries. This thesis describes the attitude and behavior in business and economic activities of Confucian citizens. How Confucianism contributed to the present form of business conduction, practices, culture and etiquette in China, Vietnam, Korea and Japan.
