Deficits in gestures act as early signs of impairment in social interaction and communication in children with autism spectrum disorder. However, the pieces of literature on atypical gesture patterns in ASD children are contradictory. This investigation aimed to explore the atypical gesture pattern of ASD children from the dimensions of quantity, communicative function, and integration ability; and its relationship with social ability and adaptive behavior. We used a semi-structured interactive play to evaluate gestures of 33 ASD children and 24 typically (...) developing children. And we evaluated the social ability, adaptive behavior, and productive language of ASD and TD children by using the Adaptive Behavior Assessment System version II and Chinese Communication Development Inventory. No matter the total score of CCDI was corrected or not, the relative frequency of total gestures, behavior regulation gestures, SI gestures, and joint attention gestures of ASD children were lower than that of TD children, as well as the proportion of JA gestures. However, there was no significant group difference in the proportion of BR and SI gestures. Before adjusting for the total score of CCDI, the relative frequency of gestures without vocalization/verbalization integration and vocalization/verbalization-integrated gestures in ASD children was lower than that in TD children. However, after matching the total score of CCDI, only the relative frequency of gestures without vocalization/verbalization integration was lower. Regardless of the fact that the total score of CCDI was corrected or not, the relative frequency and the proportion of eye-gaze-integrated gestures in ASD children were lower than that in TD children. And the proportion of gestures without eye-gaze integration in ASD children was higher than that in TD children. For ASD children, the social skills score in ABAS-II was positively correlated with the relative frequency of SI gesture and eye-gaze-integrated gestures; the total score of ABAS-II was positively correlated with the relative frequency of total gestures and eye-gaze-integrated gestures. In conclusion, ASD children produce fewer gestures and have deficits in JA gestures. The deficiency of integrating eye gaze and gesture is the core deficit of ASD children’s gesture communication. Relatively, ASD children might be capable of integrating vocalization/verbalization into gestures. SI gestures and the ability to integrate gesture and eye gaze are related to social ability. The quantity of gestures and the ability to integrate gesture with eye gaze are related to adaptive behavior.Clinical Trial Registration:www.ClinicalTrials.gov, identifier ChiCTR1800019679. (shrink)

With the assistance of the corpus analysis tool Wmatrix 4.0, this paper analyzes the semantic categories of the top 10 commercial banks of China and the United States to figure out their social-cultural behavior in the Internet business context. It is discovered that both common and distinctive identities were constructed: the common identities include the professional financial service provider, responsible corporation for employees, and relevant communities with environmental and social consciousness, while the distinctive identities are manifested in the communication strategy, (...) style, and persuasion mode: The Chinese Commercial Banks adopted the proactive strategy for corporate identity construction, are prone to take hierarchical and impersonal communication style, and more focused on the “credibility appeal” and “rational appeal” in persuasion mode; the commercial banks of the United States are more reactive in the communication strategy, position themselves in short distance with the putative audience in communication style, and conform to the typical “affective appeal” regarding the persuasion mode. From the intercultural perspective, the distinctions are the representation of the peculiar high-context culture and low-context culture based on Hofstede's cultural dimensions theory. Chinese banks should try to shorten the cultural gap by adopting communication strategy in conformity with the local cultural when going global rather than sticking to the domestic communication strategy.

Market competition is intensifying. The necessity and path of adopting the diversified management model in the media industry are explored to delve into the influence of the media diversification model and entrepreneurship on enterprise financial performance. Besides, the relevant theories such as the media diversification model and entrepreneurial spirit are expounded. Furthermore, Time Publishing & Media is taken as the representative of the media diversification model. Finally, the influence of entrepreneurship on financial performance is discussed regarding entrepreneurship in the Yangtze (...) River Delta as the research object. The profitability, solvency, and operation ability of Time Publishing & Media are analyzed. It is found that there are problems in the profitability and operation ability of Time Publishing & Media. The solvency is good, and the risk of debt repayment is low. As a result, a diversified management model may not have a positive impact on enterprise performance. In addition, the entrepreneurial spirit of the Yangtze River Delta is studied, and the results reveal that the F values from 2017 to 2019 are about 66.24, 10.78, and 60.39, respectively, with a significance of 0.00. It implies that the stronger the entrepreneur’s ability to take risks, the better the financial performance of the enterprise, but the risk should be appropriate. Therefore, the research on the influence of the media diversification model and entrepreneurship on the financial performance of enterprises in the environment of sustainable development has guided significance for enterprises to improve their business performance and market competitiveness.

Aiming at the oscillation suppression of spacecraft with large flexible appendages, we propose a control strategy using H∞ control. The weighting functions are designed for the specific flexible modes of the spacecraft and the frequency of harmonic interference in its operating environment. Taking into account the structural uncertainty of systematic modeling and the comprehensive performance requirements of system bandwidth constraint and attitude stability, the H∞ comprehensive performance matrix is constructed. A space telescope with a large flexible solar array is presented (...) as an illustrative example, and a control design that meets the requirement for pointing accuracy is proposed. The simulation results show that the designed controller satisfies the requirements of attitude stability and high pointing accuracy and has effectively suppressed the disturbance of endemic frequency. The design scheme and selection method of the weight function shown in this paper can be a reference for the controller design for oscillation suppression of this type of spacecraft with flexible structures.

Dry port construction can reduce the cost of container transportation, and its location is the focus of existing research. Considering dry port capacity limitations and scale advantages, this study calculates the costs associated with dry port construction and operations, transportation, time, and the environment and constructs a joint optimization model of the dry port location and transportation scheme to minimize the total cost. Taking 35 prefecture-level cities in Northeast China as the source of container goods and Dalian port as the (...) destination, this study conducts an empirical analysis using the Gurobi 9.0.2 optimizer of the AMPL software to solve the problem and takes the minimum total cost as the goal to select the best dry port and container transshipment scheme. The research draws the following conclusions. Seven dry ports also need to be built in the road-rail mode, which shares 82.76% of the container transshipment volume, to reduce the total transportation cost by approximately 21.67%. Although multimodal transport through dry ports increases the time cost slightly, it can significantly reduce the economic and environmental costs of container transportation. (shrink)

In this paper, we study the forcing axiom for the class of proper forcing notions which do not add ω sequence of ordinals. We study the relationship between this forcing axiom and many cardinal invariants. We use typical iterated forcing with large cardinals and analyse certain property being preserved in this process. Lastly, we apply the results to distinguish several forcing axioms.

To reduce CO2 emissions requires greater reliance on renewable sources of energy for generating electricity, especially adoption of large-scale wind generation. This study investigates possible approaches and/or policies that increase efficient use of renewable energy and reduce greenhouse gas emissions in a cost effective manner. We develop a constrained optimization model of two electricity systems to identify the impact of increasing wind generating capacity and examine how carbon prices (taxes, allowances) impact the penetration of wind power into the electricity grids. (...) Rather than employ engineering cost functions, marginal cost functions are estimated using hourly offer data from the Alberta Electric System Operator. We determine optimal removal of coal generating facilities as greater levels of wind capacity are installed in an integrated Alberta-BC electricity system; and examine the economic costs and institutional incentives that affect the ability to store intermittent wind-generated power in BC’s hydro reservoirs during low demand. The marginal shadow price of storage is zero, whichindicates that there is more than enough water behind the dams given Alberta’s relatively small demand for storage and limited intertie transmission capacity.
