Vehicular ad hoc network is a multihop mobile wireless communication network that can realize many vehicle-related applications through multitop communication. In the open wireless communication environment, security and privacy protection are important contents of VANET research. The most basic method of VANET privacy protection is anonymous authentication. Even through, there are many existing schemes to provide anonymous authentication for VANETs. Many existing schemes suffer from high computational cost by using bilinear pairing operation or need the assistance of the trust authorities (...) during the authentication process or rely on an ideal tamper-proof device, which requires very strong security assumption. In this study, an anonymous authentication and key negotiation scheme by using private key and group key is proposed, which is based on pseudonym using the nonsingular elliptic curve. In this scheme, there is no third party trust center to participate in the authentication, there is no need to query the database, and there is no need of the local database to save the identity information of many vehicles, which reduce the storage space and the authentication time compared with other schemes. The proposed scheme only needs realistic TPDs. In the proposed scheme, TPDs do not need to preinstall the system key as many other schemes do; hence, the failure of a single TPD does not affect the security of the entire system. The security of the scheme is proved under the random oracle model. Compared with the related schemes using bilinear pairings, the computational cost and communication cost of the proposed scheme are reduced by 82% and 50%, respectively. (shrink)

In a sample of 522 police officers and staff in an English police force, we investigated the role of authoritarian leadership in reducing the levels of employee ethical voice. Drawing upon uncertainty management theory, we found that authoritarian leadership was negatively related to employee ethical voice through increased levels of felt uncertainty, when the effects of a motivational-based mechanism suggested by previous studies were controlled. In addition, we found that the negative relationship between authoritarian leadership and employee ethical voice via (...) felt uncertainty is mitigated by higher levels of benevolent leadership. That is, when authoritarian leaders simultaneously exhibit benevolence, they are less likely to cause feelings of uncertainty in their followers who are then more likely to speak up about unethical issues. We discuss theoretical and practical implications of the findings. (shrink)

This research topic (RT) focused on the impact of fitness on cognitive function and development in adolescents and elderly adults from the standpoint of lifespan neuroscience. Adolescent brain development is characterized by multimodal integration of brain anatomical features and function, according to accumulating evidence. The elderly, on the other hand, suffer from age-related cognitive deterioration. Fitness may be a major factor influencing brain growth and cognitive performance throughout these two critical times for neurological development. It is a multidimensional notion that (...) includes cardiovascular fitness, muscular strength and endurance, flexibility, and body composition, as well as motor fitness (balance, agility, speed, power, and coordination). Adolescents and older people may be responsive to intervention trials aimed at improving fitness levels, such as outdoor activities, cardiovascular exercise, and mind-body practice since brain network integration and neural efficiency are rapidly altered during this period. This RT investigates how fitness influences structural and functional brain development, particularly cognitive functions, and emotional health in adolescents and elderly people, as well as training strategies that may assist cognitive progress throughout this time. It includes a clinical trial (1) and original research papers (4) on the influence of fitness on cognitive function and development in adolescents and elderly adults from a lifespan neu... (shrink)

In recent years, Liu Qingping 劉清平 has published a series of articles criticizing Confucian ethics in its modern context (see various articles by Liu), which has drawn the attention of many scholars. My friends and I have debated with him and his allies on this issue (See Guo 2002, Yang Haiwen 2002, Yang Zebo 2003, 2004a, 2004b, Ding 2003, 2005a, 2005b, Gong 2004, Guo and Gong 2004, and Wen 2005). Most of the important articles in the debate are now collected (...) in a volume I edited, A Collection of Contentions about Confucian Ethics: Focusing on the Mutual Concealment among Family Members (Guo 2005 [ed.]). In the following, I attempt to respond to some of Liu’s criticisms of Confucian ethics. (shrink)

The guide dog robot (GDR) is a low-speed companion robot that serves visually impaired people and is used to guide blind people to walk steadily, carrying a variety of intelligent technologies and needing to have the ability to guide with optimal energy consumption in specific scenarios. This paper proposes an innovative technique for virtual-real collaborative path planning and navigation of the GDR specific indoor scenarios, and designs an experimental method for virtual-real collaborative path planning of the GDR specific scenarios. The (...) energy consumption integral equation is used to solve for the energy consumption of the GDR with virtual-real synergy, and the difference in energy consumption is compared for three different navigation directions: horizontal, vertical and oblique obstacle avoidance. The results show that the optimized GDR saves 6.91% in rectilinear movement and 10.60% in curved movement. The efficiency of planning and navigating the GDR in specific domestic scenarios is verified by a virtual-real cooperative. The realization of optimal path planning for energy consumption is instrumental in exploring many of the most significant thought in the path planning and navigation of mobile robots in indoor specific scenarios.

This paper presents a formalization of the classical proof of completeness in Henkin-style developed by Troelstra and van Dalen for intuitionistic logic with respect to Kripke models. The completeness proof incorporates their insights in a fresh and elegant manner that is better suited for mechanization. We discuss details of our implementation in the Lean theorem prover with emphasis on the prime extension lemma and construction of the canonical model. Our implementation is restricted to a system of intuitionistic propositional logic with (...) implication, conjunction, disjunction, and falsity given in terms of a Hilbert-style axiomatization. As far as we know, our implementation is the first verified Henkin-style proof of completeness for intuitionistic logic following Troelstra and van Dalen's method in the literature. (shrink)

This two-volume set is a seminal work on contemporary New Confucianism in China, focusing on ten leading thinkers of this intellectual movement in the 20th century, discussing their divergences in thought and contemporary relevance. Contemporary New Confucianism refers to the Confucianism or Confucian thought that has emerged in China since the 1920s, which aims to revive the spirituality of Confucianism in a changing society. The first volume reviews the development of this intellectual trend and analyzes the cultural context, logical approach, (...) major themes, and problems of New Confucianism before delving into individual thinkers. It then examines and compares the philosophical thoughts of four key figures of contemporary New Confucianism, including Liang Shumin, Xiong Shili, Ma Yifu, Qian Mu. The second volume focuses on six other representative philosophers of New Confucianism, including Zhang Junmai, Feng Youlan, He Lin, Fang Dongmei, Tang Junyi, and Mou Zongsan. This set will appeal to scholars and students of modern and contemporary Confucianism, intellectual history, philosophy and thought of contemporary China, and comparative philosophy. (shrink)

During the past four decades, China has gone through rapid urbanization and modernization. As people adapt to dramatic sociodemographic shifts from rural communities to urban centers and as economic level rises, individualistic cultural values in China have increased. Meanwhile, parent and child behavior in early childhood has also evolved accordingly to match a more individualistic society. This mixed-method study investigated how social change in China may have impacted parenting goals and child development in middle childhood, as seen through the eyes (...) of the current generation of mothers. Thirty mothers of fifth-grade elementary school students from Shenzhen, China were recruited and took part in semi-structured interviews. Participants answered questions and provided examples about their children’s life, their own childhood, and the perceived differences between the two generations. Participating mothers were also asked to rate which generation, themselves or their parents, cared more about the childrearing goals of academic competitiveness and socioemotional well-being. Using both qualitative and quantitative analysis, we expected and found an intergenerational increase in the perceived value mothers placed on individualistic traits: current mothers care more about their children’s academic competitiveness, personal happiness, and social adjustment, compared to their experience of their own mothers’ attitudes during their childhood a generation earlier. They also experience conflict between their children’s academic competitiveness and socioemotional well-being. As a function of both urbanization and increased economic means, children’s collectivistic family responsibilities for essential household chores have declined as the importance of schoolwork has increased.
