Delay-dependent stability for uncertain cellular neural networks with discrete and distribute time-varying delays 总被引：1，自引：0，他引：1
In this paper, the problem of stability of uncertain cellular neural networks with discrete and distribute time-varying delays is considered. Based on the Lyapunov function method and convex optimization approach, a new delay-dependent stability criterion of the system is derived in terms of LMI (linear matrix inequality). In order to solve effectively the LMI as a convex optimization problem, the interior-point algorithm is utilized in this work. A numerical example is given to show the effectiveness of our results. 相似文献

ABSTRACTThis paper examines the Guyanese Mass Games, multi-media spectacles of visual and performing arts initiated by the leader of the Co-Operative Republic of Guyana and performed by Guyanese artists and youth aided by North Korean artists. North Korea and Guyana staged the games as the postcolonial and anti-imperialist expression of a newly established socialist regime in the global South in the context of the Cold War. Staged annually from 1980 to 1992 as part of the national day celebrations, they sparked debate, antagonism, and ethnic and political conflict in Guyana. The encounter of North Korean artists and Guyanese artists resulted in the new cultural tradition of the Guyanese Mass Games, which incorporated elements of Guyana's local culture into the form of the North Korean Mass Games. The paper expands the method of “inter-referencing” to incorporate a cross-continental dimension to analyze the cultural event of the Mass Games in North Korea and Guyana. The analysis in this paper is grounded in archival materials relating to the Guyanese Mass Games, such as sketch paintings, choreography books, photos, and newspaper articles, and examines how the representation of the people and land in the Mass Games captures the ambivalent character of decolonization and modernization projects in the socialist regime of Guyana. 相似文献

Inclusion has occupied the centre of attention in education in many countries for the past few decades, and it is the same in South Korea. Although most researchers and educators agree that inclusion is necessary for equal educational opportunities and social participation of students with disabilities, there are debates about the most effective and appropriate services for these students and how teachers should deliver these services. The purpose of this article is to introduce the educational system and the unique cultural situation in South Korea to the reader and to suggest future directions for successful inclusion. Inclusion can grow and be meaningful in South Korea if it is based on the thoughtful and sustained efforts of people who have the passion and compassion that inspires others to listen to different opinions. Finally, successful inclusion can come about when the government supports changes in the community and schools. 相似文献

Although 21% of all Chinese students studying at Korean universities are in graduate schools (Korean Educational Development Institute, 2008), little is known about their sociocultural adjustment. This study explores Chinese graduate students’ perceptions regarding their sociocultural adjustment experiences and capture the essence of the influences on their sociocultural adjustment during their early cross-cultural transition. The study is based on interview data from nine Chinese graduate students who attended three universities in Seoul in 2009. The model of sociocultural adjustment is employed as a conceptual framework to explore the perceptions of Chinese graduate students regarding their sociocultural adjustment. The four main themes emerged from the in-depth interview sessions were perceived cultural distance, language competency, low level of interaction with host nationals, and biased stereotypes. 相似文献

This mixed‐methods study assessed the effects of Enhanced Anchored Instruction (EAI) on the math performance of adolescents with learning disabilities in math (MLD). A quasi‐experimental pretest–posttest control group design with switching replications was used to measure students' computation and problem‐solving skills on EAI compared to control conditions. Scores on the curriculum‐aligned and standardized measures showed improved problem‐solving skills but results were mixed for computation. To augment the numerical data, a qualitative inquiry captured day‐to‐day classroom activities. The findings showed that problem‐based curricula such as EAI have the potential for helping students with MLD develop deeper understandings of math concepts but that considerable effort is required to structure and teach these concepts in ways students with MLD understand. 相似文献

The study reported in this paper focuses on the narratives of six adult Third Culture Kids (TCKs) who lived in multiple countries during developmental years. It explores their childhood experiences with mobility and the impact that multiple shifts in location, culture, and language have had on their adult lives. The results indicate that they come to terms with their identities, which are closely connected to multiple cultures and countries. Participants reported a desire to maintain nomadic lives, which may have been impacted by the multilingual competence and nuanced cultural understanding they gained through mobile upbringings. They also commonly expressed a desire to build social relationships with other individuals with migrant backgrounds. The results demonstrate the necessity of supporting the growing community of TCKs in maximizing the potential benefits of cross-cultural experiences while helping them navigate the challenges of identity, transition, and relocation. 相似文献

This study examined gender differences in information behavior concerning Wikipedia. Data were collected using a Web survey in spring 2008. The study used a convenient sample that consisted of students who had taken an introductory undergraduate course at a large public university in the Midwestern United States. A total of 134 out of 409 students participated in the study. As information consumers, male students used Wikipedia more frequently than their female counterparts did. With respect to the purposes of Wikipedia use, male students used Wikipedia for entertainment or idle reading more than their female counterparts, while there were no gender differences regarding Wikipedia use for other purposes. Male students were more likely to discount the risks involved when using Wikipedia information compared to their female counterparts. Furthermore, male students had higher ratings than female students regarding most aspects of Wikipedia, including outcome expectations, perceptions about its information quality, belief in the Wikipedia project itself, emotional states while using Wikipedia, confidence in evaluating information quality, and further exploration. Finally, there was no gender difference regarding the number of years of Wikipedia use. However, male students reported having more positive experiences with the information quality of Wikipedia than their female counterparts. Overall, the findings of this study were consistent with those of previous studies concerning gender. Given the acknowledgment of the knowledge value of Wikipedia in recent literature, it seems that there are more advantages to using Wikipedia than there are disadvantages. The current study shows that male students seem to enjoy such benefits more than female students and may have more opportunities to develop their information literacy skills than female students by actively using Wikipedia. This suggests that educators need to encourage female students in particular to explore Wikipedia strategically as an initial information source so that they can develop their information literacy skills for unconventional sources. 相似文献

In a droplet transport based on electrowetting on dielectrics, the parallel-plate configuration is more popular than the single-plate one because the droplet transport becomes increasingly difficult without cover plate. In spite of the improved transport performance, the parallel-plate configuration often limits the access to the peripheral components, requesting the removal of the cover plate, the single-plate configuration. We investigated the fundamental features of droplet transport for the single-plate configuration. We compared the performance of several switching methods with respect to maximum speed of successive transport without failure and suggested nonfloating switching method which is inherently free from the charge-residue problem and exerts greater force on a droplet than conventional switching methods. A simple theory is provided to understand the different results for the switching methods. 相似文献

Chelladurai developed the Multidimensional Model of Leadership, which was designed to be situation-specific to examine leadership behaviour and effectiveness in sporting contexts. Applying Chelladurai's concept to the Singapore sporting context, this study aimed to assess the impact of congruence between perceived and preferred leadership behaviours on satisfaction with leadership among college student-athletes in Singapore. Data were collected from 185 college student-athletes enrolled in the five local tertiary institutes. The questionnaire utilized in this study consisted of the perception and preference versions of the Revised Leadership Scale for Sports and seven items measuring satisfaction with coaching leadership. Confirmatory factor analysis and a series of hierarchical multiple regression procedures were carried out to test the psychometric properties of the leadership scale and the hypothesized relationship between congruence levels and satisfaction. Results revealed congruence of perceived and preferred behaviour in social support was a significant indicator of athletes' satisfaction. Possible implications from the findings were discussed in an effort to better understand coaching effectiveness in Singapore. 相似文献
