As a promising method with excellent characteristics in terms of resilience and dependability, distributed methods are gradually used in the field of energy management of microgrid. However, these methods have more stringent requirements on the working conditions, which will make the system more sensitive to communication failures and cyberattacks. As a result, it is both theoretical merits and practical values to investigate the malicious effect of cyber attacks on microgrid. This paper studies the distributed economic dispatch problem under denial-of-service attacks (...) for the microgrid, in which each generator can communicate with its neighbors and has the computational capability to implement local operation. Firstly, a DoS attack model is proposed, in which the DoS attacker intentionally jams the communication channel to deteriorate the performance of the microgrid. Then, the evolution mechanism of the dispatch system of the microgrid under different attack scenarios is adequately discussed. On this basis, an optimal attack strategy based on enumerating-search algorithm is presented to allocate the limited attack resources reasonably, so as to maximize the effect of DoS attacks. Finally, the validity of the theoretical studies about the attack effect under different scenarios and the effectiveness of the proposed enumerating-search-based optimal attack strategy are illustrated through the simulation examples on the IEEE 57-bus system and IEEE 39-bus system, respectively.

This paper studies the state of charge estimation of supercapacitors and lithium batteries in the hybrid energy storage system of electric vehicles. According to the energy storage principle of the electric vehicle composite energy storage system, the circuit models of supercapacitors and lithium batteries were established, respectively, and the model parameters were identified online using the recursive least square method and Kalman filtering algorithm. Then, the online estimation of SOC was completed based on the Kalman filtering algorithm and unscented Kalman (...) filtering algorithm. Finally, the experimental platform for SOC estimation was built and Matlab was used for calculation and analysis. The experimental results showed that the SOC estimation results reached a high accuracy, and the variation range of estimation error was [−0.94%, 0.34%]. For lithium batteries, the recursive least square method is combined with the 2RC model to obtain the optimal result, and the estimation error is within the range of [−1.16%, 0.85%] in the case of comprehensive weighing accuracy and calculation amount. Moreover, the system has excellent robustness and high reliability. (shrink)

This paper reports the results of a survey of 842 undergraduate business students in four nations - the United States of America, the Peoples' Republic of China, Japan, and the Republic of Korea. This survey asked students to respond to four scenarios with potentially unethical business behavior and a string of questions related to the importance of ethics in business strategy and in personal behaviors. Based on arguments related to differences in recent historical experiences, the authors suggest that student responses (...) may be as different within the East Asian environment as they are between this environment as a whole and the USA. Survey results indicate a greater perception of ethical problems and more importance placed on ethics per se in business practices, as well as less of an emphasis on social harmony on the part of USA students. At the same time, substantial national differences in response are also witnessed within the set of East Asian students. A priori expectations as to the manner in which these East Asian responses should vary based on differences in recent historical experiences are partially, but not fully, supported. The authors argue that the key value of the reported research rests on a demonstration that national differences within a common cultural area can be as great as differences across cultural areas and that practitioners of global business must fine-tune their expectations as to acceptable business and personal actions to accommodate specific national historical experiences to be effective.

The rainwater system is an important part of the urban infrastructure as well as a key hub for maintaining the dynamic operation of the city and a clear indicator of the level of urban development. With the rapid development of urbanization, the hardened area of roads and residential areas has increased, and the construction of rainwater systems is so far insufficient, causing the urban waterlogging and water pollution problems to become increasingly serious. Accordingly, combined with the “sponge city” construction concept (...) of the six-character policy of “seepage, retention, storage, use, purification, and drainage,” we propose to adopt measures for the local conditions and to reasonably select sponge city engineering measures to increase rainwater utilization, effectively reduce rainwater runoff, and alleviate the city waterlogging and water pollution problems. We used the analytic hierarchy process to evaluate the effect of a sponge city “pocket park” rainwater system in Chaohu City before and after the transformation. The results showed that the pocket park after the renovation was well controlled, the waterlogging was basically eliminated, the water quality pollution was clearly improved, and the ecological environment was significantly improved.

We examine whether investors value the disclosure of first-time standalone corporate social responsibility reports, and whether market valuations differ between government-controlled and privately controlled firms. Using a matched sample of Chinese publicly listed firms, we find that CSR initiators have higher market valuations than matched CSR non-initiators, and CSR initiators controlled by the central and local governments have lower market valuations than CSR non-initiators and CSR initiators controlled by private shareholders. Additional analyses demonstrate that CSR initiators with high CSR reporting (...) quality and perceived credibility have higher market valuations than CSR initiators with low CSR reporting quality and medium or low perceived credibility of CSR reporting. We do not find convincing evidence that CSR mandate, litigation risk, and prior stock returns affect market reactions to CSR reporting. Overall, we find that the market values standalone CSR reports, and that CSR reporting quality and perceived credibility are important factors in market valuation. (shrink)

Corporate social responsibility reporting is becoming mainstream, yet there is limited research on whether and how CSR reports communicate value relevant information. We examine the effects of CSR report readability and tone on future CSR performance and the market reaction around the release of CSR reports. Using a hand-collected dataset of Fortune 500 companies that published stand-alone CSR reports from 2002 to 2014, we find that 1-year-ahead CSR performance is positively associated with the changes in both CSR report readability and (...) tone, suggesting that more readable text and more optimistic tone in a firm’s CSR report are indicative of better future CSR performance. Furthermore, consistent with the view that CSR reports communicate important value relevant information to the market, we document significant market reactions to report readability and tone around the release of CSR reports. Additional analyses suggest that CSR report readability enhances the association between the abnormal returns and the change in CSR report tone, and that the market reaction to CSR report readability is more pronounced for firms with lower analyst following and higher financial opacity. Taken together, our results substantiate the important roles of CSR report readability and tone in communicating future CSR performance and imparting value relevant information to the market.

Long before Wittgenstein drew attention to its complexities, the concept of play had captured the interest of theorists for millennia. How do games contribute to our knowledge of the world? Wherein lies their universal appeal? Play is usually associated with a certain blitheness and buoyancy - could it nevertheless be argued that playfulness is not quite as innocent as it might seem? Bence Kun draws on Adorno's writings to explore the relation between philosophical play (understood here as imaginative thought as (...) well as experimental expression) and an experience of dread Adorno links to children's first encounter with death. By investigating his less familiar works, some of which have not yet been translated, Kun challenges the received view on Adorno's approach to metaphysics, the role of systematic inquiry and the modern condition. As he has Adorno say, the originary impression of shock at the heart of philosophical reflection can only be fully apprehended through an open-ended and defiantly creative intellectual practice.

This paper reports the results of a survey of 842 undergraduate business students in four nations - the United States of America (the USA), the Peoples' Republic of China (the PRC), Japan, and the Republic of Korea (the ROK). This survey asked students to respond to four scenarios with potentially unethical business behavior and a string of questions related to the importance of ethics in business strategy and in personal behaviors. Based on arguments related to differences in recent historical experiences, (...) the authors suggest that student responses may be as different within the East Asian (Confucian) environment as they are between this environment as a whole and the USA. Survey results indicate a greater perception of ethical problems and more importance placed on ethics per se in business practices, as well as less of an emphasis on social harmony (a key distinguishing characteristic of Confucian values identified in prior research) on the part of USA students. At the same time, substantial national differences in response are also witnessed within the set of East Asian students. A priori expectations as to the manner in which these East Asian responses should vary based on differences in recent historical experiences are partially, but not fully, supported. The authors argue that the key value of the reported research rests on a demonstration that national differences within a common cultural (e.g., East Asian or Confucian) area can be as great as differences across cultural (East vs. West) areas and that practitioners of global business must fine-tune their expectations as to acceptable business and personal actions to accommodate specific national historical experiences to be effective.

Previous studies of the lexical psycholinguistic properties in second language production have assessed the degree of an LPP dimension of an L2 corpus by computing the mean ratings of unique content words in the corpus for that dimension, without considering the possibility that learners at different proficiency levels may perceive the degree of that dimension of the same words differently. This study extended a dynamic semantic similarity algorithm to estimate the degree of five different LPP dimensions of several sub-corpora of (...) the Education First-Cambridge Open Language Database representing L2 English learners at different proficiency levels. Our findings provide initial evidence for the validity of the algorithm for assessing the LPPs in L2 production and contribute useful insights into between-proficiency relationships and cross-proficiency differences in the LPPs in L2 production as well as the relationships among different LPP dimensions.

Under the hit of the epidemic, an increasing number of young people exchange and purchase goods by watching and resorting to mobile short video advertisements. Therefore, it is of great significance to explore the influence mechanism of mobile short video advertising on the consumption behavior of young people. This study develops a theoretical framework including fashion, socialization, entertainment, personalization, brand, psychological needs, satisfaction, and consumption behavior using a stimulus–organism–response (SOR) theory. The data from 332 young people using mobile short video (...) advertising revealed that psychological needs exerted significant impacts on satisfaction, mediating the advertisements, and consumer satisfaction. The attributes of advertising, including fashion, socialization, entertainment, personalization, and branding, significantly promote young people’s psychological needs and satisfaction. In addition, satisfaction affects consumer behavior, and in the same manner, fashion and brand attribute directly impact consumer satisfaction. (shrink)

The present study explored the correlation between music preference and mental health of college students to make an empirical contribution to research in this field. The self-reported music preference scale and positive mental health scale of college students were adopted to conduct a questionnaire survey in college students. Common method variance was conducted to test any serious common method bias problem. No serious common method bias problem was observed. The results showed that college students’ preference for pop music, Western classical (...) music, and Chinese traditional music has a significant and positive correlation with their mental health. Furthermore, college students’ preference for heavy music has a significant and inverse correlation with their mental health. This research presents a correlational study; therefore, no causality can be inferred. (shrink)
