In this paper, we present a functional variable method for finding periodic wave and solitary wave solutions of complex nonlinear evolution equations in mathematical physics and engineering sciences. The proposed technique is tested on the generalized Zakharov equation and higher-order nonlinear Schrödinger equations. The method is straightforward and concise, and it can also be applied to other nonlinear evolution equations in applied mathematics. 相似文献

This study investigates the antecedents and consequences of team learning, which is composed of information acquisition, dissemination, and implementation, in information technology (IT) implementation projects. By investigating 129 IT implementation project teams, we found that (1) information acquisition and information dissemination have a positive impact on project outcomes, such as speed-to-users, lower implementation cost, and operational effectiveness, and (2) team behavior and enabler variables, such as teamwork, team communication, interpersonal trust between team members, team commitment, and senior manager support, positively influence team learning. We also found that team anxiety moderates the relationship between team learning and project outcomes. 相似文献

Welcome to the Global Postcards column! We are so excited to bring you news and projects from around the world. In this column, our contributors from Bulgaria and Turkey bring us a comparative study of mobile and information literacy among students at two universities in those countries. In addition to presenting perceptions of students around these literacy concepts, their research project also highlights growing trends in the use of distance education and web-based study materials. Thanks to the contributors for this issue, and please keep the submissions coming!

In this paper, we are interested in the following general question: Given a module Mwhich has finite hollow dimension and which has a finite collection of submodules Ki (1≤i≤n) such that M=K1 ... Kn, can we find an expression for the hollow dimension of Min terms of hollow dimensions of modules built up in some way from K1 Kn? We prove the following theorem:Let Mbe an amply supplemented module having finite hollow dimension and let Ki (1≤i≤n) be a finite collection of submodules of Msuch that M=K1 ... Kn. Then the hollow dimension h(M) of Mis the sum of the hollow dimensions of Ki (1≤i≤n) ifand only if Ki is a supplement of K1 ... Ki-1 Ki 1 ... Kn in Mfor each 1≤i≤n. 相似文献

This research was carried out to investigate the effect of the 5E learning method and 5E method enriched with REACT strategy on student achievement in science education. The research was carried out with 64 first-year students (30 in the experimental groups, 34 in the control groups) in the Department of Primary Education at a state university in the spring semester of 2017–2018 in the context of “Acids, Bases and Salts”. The pre-test/post-test quasi-experimental design with a control group was used in this study. In the experimental group, the 5E method enriched with the REACT strategy was used while the computer-assisted 5E instruction method was used in the control group. The data were collected by means of a “Subject Achievement Test”, consisting of open-ended questions. The dependent t test results of the experimental and control group revealed a significant difference in favour of the post-test in both groups. According to the independent t test results of the groups, the 5E method enriched with REACT strategy was found to be more effective in order to improve student achievement compared to computer-assisted 5E learning method.

This study explored the structural relationships among secondary school students’ conceptions, self-regulation, and strategies of learning science in mainland China. Three questionnaires, namely conceptions of learning science (COLS), self-regulation of learning science (SROLS), and strategies of learning science (SLS) were developed for investigating 333 Chinese high school learners’ conceptions, metacognitive self-regulation, and strategies in science. The confirmatory factor analysis results verified the validity of the three surveys. Moreover, the path analyses revealed a series of interesting findings. Learners with lower-level COLS, namely “memorizing,” “testing,” and “practicing and calculating,” tended to use surface learning strategies such as “minimizing scope of the study” and “rote learning.” However, learners’ higher-level COLS, namely “increase of knowledge,” “applying,” “understanding,” and “seeing in a new way,” had complicated connections with their SROLS and SLS. On the one hand, learners’ higher-level COLS had negative relations to “minimizing scope of the study” and “rote learning.” On the other hand, their higher-level COLS were powerful predicators for their metacognitive self-regulation and further affected their use of “deep strategy” and “rote learning.” Though Chinese secondary students with higher-level COLS usually have a negative view of “rote learning,” the functioning of their metacognitive self-regulation may change their initial attitudes towards the surface strategy. Learners with higher-level COLS still used “rote learning” as a prior step for achieving deep learning. Therefore, we concluded that the SROLS played an important mediating role between the COLS and SLS and may change learners’ original intention to utilize learning strategies. 相似文献
