Zhodnocení výkonnosti nemovitostních akcií v Číně
This thesis is focused on real estate investment in China. After reform and opening up, the government has taken growth of GDP as an important aim. When the natural growth rate of the economy is lower than the declared target growth rate, the huge political inertia will force the government to intervene in the market, at the expense of resource mismatch to push GDP to achieve the goal. Especially in the thirty years after the marketization of real estate, the real estate industry in China has greatly improved the housing, consumption and urban landscapes of the huge population in China. It brought up about 60 industrial developed and have a significant impact on the Chinese economy and caused the high growth speed of houses’ price. With the competition is becoming more fierce, it is necessary to evaluate the current condition of real estate equity investment in China and if the property bubble will break in the future. The objective of the work is examining the changes in real estate equity investment performance across fifty selected real estate companies in China over the period 2000-2017. This thesis attempts to investigate how stocks of companies in real estate performed before financial crisis (2000-2008) and after crisis (2008-2017).Tato práce je zaměřena na investice do nemovitostí v Číně. Po reformě vláda považuje růst HDP za důležitý cíl. Když je přirozená míra růstu ekonomiky nižší než deklarovaná cílová míra růstu, politická setrvačnost přiměje vládu k intervenci na trhu, a to na úkor nesouladu zdrojů s cílem posunout HDP k dosažení tohoto cíle. Zejména v třiceti letech v souvislosti se změnami na trhu nemovitostí se v Číně výrazně zlepšilo bydlení. Vyvinulo se přibližně 60 průmyslových průmyslových odvětví, což významně ovlivnilo čínskou ekonomiku a způsobilo vysokou rychlost růstu cen nemovitostí. Vzhledem k tomu, že se konkurence stává stále silnější, je třeba zhodnotit současný stav investic do nemovitostí do nemovitostí v Číně a v případě, že bublina nemovitostí v budoucnu naruší. Cílem práce je prozkoumat změny v investiční výkonnosti nemovitostí ve více než padesáti vybraných realitních společnostech v Číně v období 2000-2017. Tato práce se pokouší prověřit, jak se akcie společností v oblasti nemovitostí prováděly před finanční krizí (2000-2008) a po krizi (2008-2017).154 - Katedra financídobř

Incongruent gestures slow the processing of facial expressions in university students with social anxiety
In recent years, an increasing number of studies have examined the mechanisms underlying nonverbal emotional information processing in people with high social anxiety (HSA). However, most of these studies have focused on the processing of facial expressions, and there has been scarce research on gesture or even face-gesture combined processing in HSA individuals. The present study explored the processing characteristics and mechanism of the interaction between gestures and facial expressions in people with HSA and low social anxiety (LSA). The present study recruited university students as participants and used the Liebowitz Social Anxiety Scale scores to distinguish the HSA and LSA groups. We used a 2 (group: HSA and LSA) × 2 (emotion valence: positive, negative) × 2 (task: face, gesture) multifactor mixed design, and videos of a single face or gesture and combined face-gesture cues were used as stimuli. We found that (1) there is a distinction in the processing of faces and gestures, with individuals recognizing gestures faster than faces; (2) there is an attentional enhancement in the processing of gestures, particularly for negative gestures; and (3) when the emotional valence of faces and gestures align, it facilitates the recognition of both. However, incongruent gestures have a stronger impact on the processing of facial expressions compared to facial expressions themselves, suggesting that the processing of facial emotions is more influenced by environmental cues provided by gestures. These findings indicated that gestures played an important role in emotional processing, and facial emotional processing was more dependent on the environmental cues derived from gestures, which helps to clarify the reasons for biases in the interpretation of emotional information in people with HSA
DANAA: Towards transferable attacks with double adversarial neuron attribution
While deep neural networks have excellent results in many fields, they are
susceptible to interference from attacking samples resulting in erroneous
judgments. Feature-level attacks are one of the effective attack types, which
targets the learnt features in the hidden layers to improve its transferability
across different models. Yet it is observed that the transferability has been
largely impacted by the neuron importance estimation results. In this paper, a
double adversarial neuron attribution attack method, termed `DANAA', is
proposed to obtain more accurate feature importance estimation. In our method,
the model outputs are attributed to the middle layer based on an adversarial
non-linear path. The goal is to measure the weight of individual neurons and
retain the features that are more important towards transferability. We have
conducted extensive experiments on the benchmark datasets to demonstrate the
state-of-the-art performance of our method. Our code is available at:

The influence of responsible leadership on teachers’ green behavior: The mediating role of psychological capital
This research aimed to explore the impact of responsible leadership on teachers’ green behavior in Chinese university, and applied psychological capital as a mediator variable to establish a research model. A questionnaire was conducted with 303 teachers using convenience sampling. SPSS version 19 was used to analyze the data and Sobel was used to test the mediating relationships. The results show that responsible leadership has a positive yet significant effect on teachers’ green behavior. It also shows positive impact on psychological capital. Furthermore, psychological capital is shown to positively impact teachers’ green behavior, while having a mediating effect between responsible leadership and teachers’ green behavior. This study enriches the research of teachers’ green behavior and fill the gap in previous education management research. The research conclusions enable managers to better understand teachers’ green behavior and provides them with theoretical guidance for promoting psychological capital and improving teachers’ green behavior

Guided Online Distillation: Promoting Safe Reinforcement Learning by Offline Demonstration
Safe Reinforcement Learning (RL) aims to find a policy that achieves high
rewards while satisfying cost constraints. When learning from scratch, safe RL
agents tend to be overly conservative, which impedes exploration and restrains
the overall performance. In many realistic tasks, e.g. autonomous driving,
large-scale expert demonstration data are available. We argue that extracting
expert policy from offline data to guide online exploration is a promising
solution to mitigate the conserveness issue. Large-capacity models, e.g.
decision transformers (DT), have been proven to be competent in offline policy
learning. However, data collected in real-world scenarios rarely contain
dangerous cases (e.g., collisions), which makes it prohibitive for the policies
to learn safety concepts. Besides, these bulk policy networks cannot meet the
computation speed requirements at inference time on real-world tasks such as
autonomous driving. To this end, we propose Guided Online Distillation (GOLD),
an offline-to-online safe RL framework. GOLD distills an offline DT policy into
a lightweight policy network through guided online safe RL training, which
outperforms both the offline DT policy and online safe RL algorithms.
Experiments in both benchmark safe RL tasks and real-world driving tasks based
on the Waymo Open Motion Dataset (WOMD) demonstrate that GOLD can successfully
distill lightweight policies and solve decision-making problems in challenging
safety-critical scenarios
