Speech recognition technology has played an indispensable role in realizing human-computer intelligent interaction. However, most of the current Chinese speech recognition systems are provided online or offline models with low accuracy and poor performance. To improve the performance of offline Chinese speech recognition, we propose a hybrid acoustic model of deep convolutional neural network, long short-term memory, and deep neural network. This model utilizes DCNN to reduce frequency variation and adds a batch normalization layer after its convolutional layer to ensure (...) the stability of data distribution, and then use LSTM to effectively solve the gradient vanishing problem. Finally, the fully connected structure of DNN is utilized to efficiently map the input features into a separable space, which is helpful for data classification. Therefore, leveraging the strengths of DCNN, LSTM, and DNN by combining them into a unified architecture can effectively improve speech recognition performance. Our model was tested on the open Chinese speech database THCHS-30 released by the Center for Speech and Language Technology of Tsinghua University, and it was concluded that the DLD model with 3 layers of LSTM and 3 layers of DNN had the best performance, reaching 13.49% of words error rate.

Depression is a common mental health illness worldwide that affects our quality of life and ability to work. Although prior research has used EEG signals to increase the accuracy to identify depression, the rates of underdiagnosis remain high, and novel methods are required to identify depression. In this study, we built a model based on single-channel, dry-electrode EEG sensor technology to detect state depression, which measures the intensity of depressive feelings and cognitions at a particular time. To test the accuracy (...) of our model, we compared the results of our model with other commonly used methods for depression diagnosis, including the PHQ-9, Hamilton Depression Rating Scale, and House-Tree-Person drawing test, in three different studies. In study 1, we compared the results of our model with PHQ-9 in a sample of 158 senior high students. The results showed that the consistency rate of the two methods was 61.4%. In study 2, the results of our model were compared with HAM-D among 71 adults. We found that the consistency rate of state-depression identification by the two methods was 63.38% when a HAM-D score above 7 was considered depression, while the consistency rate increased to 83.10% when subjects showed at least one depressive symptom. In study 3, 68 adults participated in the study, and the results revealed that the consistency rate of our model and HTP drawing test was 91.2%. The results showed that our model is an effective means to identify state depression. Our study demonstrates that using our model, people with state depression could be identified in a timely manner and receive interventions or treatments, which may be helpful for the early detection of depression.

As an important component to promote the development of affective brain–computer interfaces, the study of emotion recognition based on electroencephalography (EEG) has encountered a difficult challenge; the distribution of EEG data changes among different subjects and at different time periods. Domain adaptation methods can effectively alleviate the generalization problem of EEG emotion recognition models. However, most of them treat multiple source domains, with significantly different distributions, as one single source domain, and only adapt the cross-domain marginal distribution while ignoring the (...) joint distribution difference between the domains. To gain the advantages of multiple source distributions, and better match the distributions of the source and target domains, this paper proposes a novel multi-source joint domain adaptation (MSJDA) network. We first map all domains to a shared feature space and then align the joint distributions of the further extracted private representations and the corresponding classification predictions for each pair of source and target domains. Extensive cross-subject and cross-session experiments on the benchmark dataset, SEED, demonstrate the effectiveness of the proposed model, where more significant classification results are obtained on the more difficult cross-subject emotion recognition task.

The developmental trajectory of speechreading skills is poorly understood, and existing research has revealed rather inconsistent results. In this study, 209 Chinese students with hearing impairment between 7 and 20 years old were asked to complete the Chinese Speechreading Test targeting three linguistics levels. Both response time and accuracy data were collected and analyzed. Results revealed no developmental change in speechreading accuracy between ages 7 and 14 after which the accuracy rate either stagnates or drops; no significant developmental pattern in (...) speed of speechreading across all ages. Results also showed that across all age groups, speechreading accuracy was higher for phrases than words and sentences, and overall levels of speechreading speed fell for phrases, words, and sentences. These findings suggest that the development of speechreading in Chinese is not a continuous, linear process. (shrink)

BackgroundThe neural activity of irritable bowel syndrome patients in the resting state without any intervention has not been systematically studied. The purpose of this study was to compare the resting-state brain functions of IBS patients with healthy controls.MethodsThe published neuroimage studies were obtained from electronic databases including PubMed, EMBASE, PsycINFO, Web of Science Core, CNKI Database, Wanfang Database, VIP Database, and CBMdisc. Search dates were from inception to March 14th, 2022. The studies were identified by the preidentified inclusion and exclusion (...) criteria. Two independent reviewers compiled the studies and evaluated them for quality and bias.ResultsAltogether 22 fMRI studies were included in this review. The risk of bias of the included studies was generally low. The findings indicated that in IBS patients, increased or decreased brain areas were mostly associated with visceral sensations, emotional processing, and pain processing. According to brain network research, IBS may exhibit anomalies in the DMN, CEN, and emotional arousal networks. The fluctuations in emotion and symptoms in IBS patients were associated with alterations in the relevant brain regions.ConclusionThis study draws a preliminary conclusion that there are insufficient data to accurately distinguish the different neurological features of IBS in the resting state. Additional high-quality research undertaken by diverse geographic regions and teams is required to reach reliable results regarding resting-state changed brain regions in IBS. (shrink)

Window opening behavior in residential buildings has important theoretical significance and practical value for improving energy conservation, indoor thermal comfort, and indoor air quality. Climate and cultural differences may lead to different window opening behavior by residents. Currently, research on residential window opening behavior in northwest China has focused on indoor air quality, and few probabilistic models of residential window behaviors have been established. Therefore, in this study, we focused on an analysis of factors influencing window opening behavior and the (...) establishment of a predictive model for window opening behavior. Four typical residential buildings in different locations and building types in Xi’an were selected. The indoor and outdoor environments and window opening states were measured. Subsequently, a multivariate analysis of variance was used to determine the factors that had a significant effect on window opening behavior. Single- and multiparameter logistic regression models for window opening behavior were established. Of all the measured factors, we found that indoor temperature and CO2 concentration, outdoor temperature, and relative humidity had significant effects on window opening behavior, and indoor relative humidity and noise did not. Meanwhile, the temperature was positively correlated with the window opening probability, whereas indoor CO2 concentration and outdoor relative humidity were negatively correlated. The prediction accuracy of the multiparameter model was promising, at almost 75%, and the model can provide theoretical support for modelling residential buildings in Xi’an. (shrink)

The pandemic has catalysed to hasten the wider use of virtual hearings in international arbitration. However, the promotion of virtual hearings in international commercial dispute resolution was more complex than commonly thought due to the highlighted concerns of cybersecurity and breach of confidentiality in arbitration. The worries against the wide use of virtual hearings cannot stand because technological innovations can largely improve and solve this. However, virtual arbitration hearings may not be common post-COVID times. Technology shapes how people behave, interact, (...) grow, and develop in their relationships with others and wider communities. Yet greater immersion in the digital world undoubtedly creates new challenges and can adversely affect human-to-human interactions. There is very little scientific study on the psychological impacts of virtual hearings on arbitrators, witnesses and counsels. It is too early to assess its effectiveness from the user's perspective until the much-needed scientific data is released. Virtual hearings are unlikely to replace in-person ones necessary for more complex and high-value disputes requiring greater interaction and personal connection. Strategically, international arbitration is a private initiative-orientated, flexible, and market-driven dispute resolution mechanism. The parties are best positioned to choose the hearing format after balancing off. (shrink)

The study of dialectical logic has a history of nearly one hundred years in China. It is significant for understanding both the growth of Chinese logic and the Sinicization of Marxism to review dialectical logic in the context of introducing the study of Marxism in China. Debates about dialectical logic in Chinese academic circles involve not only the problems of logic itself, but more importantly the understanding of Marxist philosophy. In the 1920s and 1930s, some Marxist researchers in China were (...) influenced by the philosophers and logicians of the former Soviet Union, and they came very close to equating dialectical logic with Marxist dialectics. They also identified the formal logic originating from ancient Greece as metaphysics, praising the former and criticizing the latter. In the upsurge of Marxist philosophy in the 1950s and 1960s, Chinese logicians carried out normal and formal academic research on dialectical logic. During the period from the end of 1970s to the end of 1990s, the research and teaching of dialectical logic in China reached its heyday, and logicians performed comprehensive and detailed research on some critical issues, including the basic laws of dialectical logic, which they tried to formalize. Since the beginning of the 21st century, dialectical logic has ceased to prosper and has faded from the core field of the discipline of logic, although some honorable scholars still persist in studying it.

Our paper draws attention to a neglected channel of corruption—the bribe payments by state-owned enterprises. This is an important phenomenon as bribe payments by SOEs fruitlessly waste national resources, compromising public welfare and national prosperity. Using a large dataset of 30,249 firms from 50 countries, we show that, in general, SOEs are less likely to pay bribes for achieving organizational objectives owing to their political connectivity. However, in deteriorated institutional environments, SOEs may be subjected to potential managerial rent-seeking behaviors, which (...) disproportionately increase SOE bribe propensity relative to privately owned enterprises. Specifically, our findings highlight the importance of fostering democracy and rule of law, reducing prevalence of corruption and shortening power distance in reducing the incidence of SOE bribery.

The subject of the study is the works of contemporary St. Petersburg artists of different generations and creative trends, as well as the forms and features of their communication with each other and with the general as well as professional public. The trends of artistic communication in the city are determined by the activities of such institutions as art and non-art museums, art galleries and exhibition centers, which are a classic form of presentation of contemporary art; alternative venues such as (...) creative spaces and art clusters. The field of attention also includes the attraction of St. Petersburg authors to the organization of small artistic associations, mainly art groups, for example, "Unconquered", "North-7", "Parasites", etc. In addition to works of art, theoretical works and reflections by researchers of contemporary art in St. Petersburg and the spaces of its public presentation are involved. The methodological basis is the analysis of the works of St. Petersburg masters of the beginning of the XXI century in the context of the development of urban institutions of artistic communication. The research is based on theoretical works devoted to the problem of artistic communication and trends in the current art process. Comparative-interpretative and typological methods are used to compare the works of artists and forms of artistic communication. The problem of artistic communication in the field of fine art in St. Petersburg is becoming the subject of a separate study. This area of city life is currently developing quite dynamically, as new art associations, curatorial practices and alternative classical platforms for the presentation of the work of authors belonging to different generations and art movements are emerging. Traditional museums and galleries, as well as creative spaces, art clusters and other often non-core institutions, such as libraries and cafes, are involved in this process. Against this background, the features of St. Petersburg artistic communication crystallize, which is characterized by a desire to organize communities, to fuse realistic traditions and current trends, to escapism and symbolism, as well as an interest in oriental themes and stylistics.

As teams of people increasingly incorporate robot members, it is essential to consider how a robot's actions may influence the team's social dynamics and interactions. In this work, we investigated the effects of verbal support from a robot on human team members' interactions related to psychological safety and inclusion. We conducted a between-subjects experiment where the robot team member either gave verbal support or did not give verbal support to the human team members of a human-robot team comprised of 2 (...) human ingroup members, 1 human outgroup member, and 1 robot. We found that targeted support from the robot had a positive effect on outgroup members, who increased their verbal participation after receiving targeted support from the robot. When comparing groups that did and did not have verbal support from the robot, we found that outgroup members received fewer verbal backchannels from ingroup members if their group had robot verbal support. These results suggest that verbal support from a robot may have some direct benefits to outgroup members but may also reduce the obligation ingroup members feel to support the verbal contributions of outgroup members.

This article focuses on the 1952 visit to the Jingjiang Flood Diversion Project, the first large-scale water infrastructure built on the Yangzi river after the founding of the People's Republic of China, by a foreign delegation from the Asia-Pacific Peace Conference. Serving as a form of technology diplomacy, this trip advanced two main purposes for the newly established country – to build up closer ties with ‘foreign friends’ who advocated international peace in the context of the Korean War, and to (...) demonstrate China's own technical capabilities and achievements as part of the national campaign of ‘peaceful construction’ of the early 1950s. I argue that vernacular technologies, which were grounded in indigenous knowledge and practices for water control in the mid-Yangzi region, were essential in shaping China's self-reliant modernization and China's public diplomacy, which targeted individuals without scientific or technical backgrounds.

The automated valuation of benchmark land price plays an essential role in regulating land demand in Chinese real-estate market as the big data are currently accumulated rapidly. However, this problem becomes highly challenging due to the multidimension, large volume, and nonlinearity of the land price-influencing factors. In this paper, an effective data-driven automated valuation framework is proposed for valuing real estate assets by combining a GIS and neural network technologies. This framework can automatically obtain the values of spatial factors affecting (...) land price from GIS and generate training set data for training the neural network to identify the complex relationship between all kinds of factors and benchmark land prices. The effectiveness and universality of the framework is verified via the data of benchmark land prices in Wuhan. The framework can be applied for automated benchmark land price valuation in other cities. (shrink)
