Seismic data denoising based on learning-type overcomplete dictionaries

The transform base function method is one of the most commonly used techniques for seismic denoising, which achieves the purpose of removing noise by utilizing the sparseness and separateness of seismic data in the transform base function domain. However, the effect is not satisfactory because it needs to pre-select a set of fixed transform-base functions and process the corresponding transform. In order to find a new approach, we introduce learning-type overcomplete dictionaries, i.e., optimally sparse data representation is achieved through learning and training driven by seismic modeling data, instead of using a single set of fixed transform bases. In this paper, we combine dictionary learning with total variation （TV） minimization to suppress pseudo-Gibbs artifacts and describe the effects of non-uniform dictionary sub-block scale on removing noises. Taking the discrete cosine transform and random noise as an example, we made comparisons between a single transform base, non-learning-type, overcomplete dictionary and a learning-type overcomplete dictionary and also compare the results with uniform and nonuniform size dictionary atoms. The results show that, when seismic data is represented sparsely using the learning-type overcomplete dictionary, noise is also removed and visibility and signal to noise ratio is markedly increased. We also compare the results with uniform and nonuniform size dictionary atoms, which demonstrate that a nonuniform dictionary atom is more suitable for seismic denoising.

Why women see differently from the way men see? A review of sex differences in cognition and sports

The differences of learning and memory between males and females have been well documented and confirmed by both human and animal studies. The sex differences in cognition started from early stage of neuronal development and last through entire lifespan. The major biological basis of the gender-dependent cognitive activity includes two major components： sex hormone and sex-related characteristics, such as sex- determining region of the Y chromosome （SRY） protein. However, the knowledge of how much biology of sex contributes to normal cogni- tive function and elite athletes in various sports are still pretty limited. In this review, we will be focusing on sex differences in spatial learning and memory -- especially the role of male- and female-type cognitive behaviors in sports.

Two in One： The Collaboration Between Science Foundation Lecturers in Imparting Academic Skills to Students

Learning challenges are more common in the 21 st century than many people believe; however, there are more efficient and better methods to develop academic learning skills for students. Identifying learning problems can help both students and lecturers to apply specific learning techniques and work together to be more productive in the process of teaching and learning. This study investigates the collaboration of science foundation lecturers in addressing the students＇ academic performance and challenges in their foundation modules at the University of Venda. The study is also aimed at finding out whether students can be able to apply their information technology （IT） skills in other modules and they make use of group work in projects into different foundation modules to enhance performance and develop academic learning skills. In this study, students were given projects in their respective modules （Foundation Biology and Foundation IT） and it was required to them to make use of their IT skills during the research report and also during the presentation of their project. These projects were done in groups wherein students undertook some mini researches. Their findings were then reported in writing and presentations were held. The Foundation English lecturer helped in assessing the use of the academic language used in writing and during oral presentations. The findings from these projects were that students＇ academic performance and skills improved and their specific knowledge in those modules also improved radically. It was found that group work plays a very imperative role in enhancing the students＇ performance and collaboration in various foundation modules.

Building an Ecological Civilization in China： Towards a Practice Based Learning Approach

The adoption by the 18th Congress of the Communist Party of China in November 2012 of a policy on ecological civilization is a landmark event for the nation and the world community. China＇s vision for building an ecological civilization is comprehensive, multi-sectoral and systemic and is intended to direct and balance progress among ecological, economic, social, cultural and political dimensions of change. Some on-going efforts and potential future activities that meet China＇s vision of an ecological civilization are described. Establishment of dedicated ecological civilization areas for experimenting with legal, regulatory and administrative incentives that would facilitate the march towards the ideal is encouraged. Chinese biosphere reserves which are designated with the explicit aim of building harmony between humans and nature would be suitable candidates for designing and developing such dedicated ecological civilization areas.

Conversing in Spanish at a Seniors Center： A Brief Experience of Community-Based and Foreign-Language Learning

This pilot study explored the linguistic gains of intermediate level Spanish learners who completed community-based learning at a Spanish-speaking seniors center. Leamers had the opportunity, rare in foreign-language instruction, to discuss topics from their textbook in authentic native/non-native dyads. The interactions also allowed the seniors to fulfill an identified community needed by socializing in Spanish. Analyses of a post-service survey revealed that learners assessed the experience positively, because they spoke Spanish creatively. Seniors were described as cooperative and fun interlocutors, suggesting that age difference minimally affected the interactions. Direct observation revealed that learners managed to produce L2 Spanish output in connected speech for an extended period of time. Likewise, the seniors enjoyed a moment of socialization and first language use while sharing their views on the topics of discussion with the young visitors. Seniors＇ active participation likely encouraged learners to cope with sudden switches of topics that required negotiating for meaning and pushing the still limited interlanguages. A new service leaming study proposes to investigate the use of native/non-native dyads in Spanish in fulfilling a dual function： socialization and first language maintenance for the seniors at the center and language learning for the students.

A Corpus-Based Approach to the Vocabulary Teaching and Learning--Implications From the Corpus-Based Collocational Research on Two Pairs of Synonyms

Languages embody a lot of words that are considered as synonyms, and people just take it for granted that such words are identical in meaning without any discrimination. However, a corpus-based approach to the study of the collocational behavior of the two frequently-used pairs of synonyms （selection and option, ill and sick） reveals significant discrepancies in the use of these two pairs of synonyms by Chinese English learners and native speakers. According to the analysis, the major problems lie in the current ways of vocabulary teaching and learning. This paper aims to highlight the important role of the corpus-based collocational research in English vocabulary teaching and learning. In the end, some suggestions concerning vocabulary teaching and leaming are put forward on the basis of corpus-based research.

Exploring English Language Learning Policies in Iran Based on Secondary School Course Books for Learning English in Light of Globalization and Culture

With the globalization of English, the macro and micro cultures of the users of English around the world interact intensively. Considering these conditions, the local and global cultural interface seems an important issue which needs to be clarified in the materials and books used for learning English. Thus, the focus of this study was to explore the language learning policy of the new Iranian English course book at high schools, Prospect 1, recently published and taught for a year in Iran, in light of globalization and culture. This qualitative study was conducted through carrying out semi-structured interviews. The participants of this study were 30 teachers of Ministry of Education, who had the experience of teaching Prospect I for a year and they were mostly chosen from Mashhad and the rest from other cities of Khorasan province, Iran. The interview contained four main questions which were posed to the teachers. The findings of the study indicate that the language learning policy of Iran need to pay more attention to the learners＇ intercultural communicative competence because it mainly attempts at teaching English language focusing on the home culture in the Iranian context. The article ends with some pedagogical implications and more recommendations for developing research studies.

Foreign Language Teacher Recruitment： Theoretical Perspectives and Empirical Findings

In some contexts such as private language schools of Iran language teachers are recruited mainly on the basis of their speaking fluency and in other EFL contexts they are recruited simply because they are native speakers. Moreover, previous studies mainly focus on comparing the effectiveness of native and non-native language teachers by exploring learners＇ and teachers＇ perceptions of native and non-native language teachers. Since recruitment criteria are theoretically unjustified and the results of previous studies are subjective and inconclusive, this study aims at making a case in the opposite direction. That is, the researchers argue that there should be： （1） a shift away from recruiting language teachers on the basis of their speaking fluency and native language background towards hiring language teachers on the basis of their professional performance in the language classroom; （2） a shift away from exploring learners＇ and teachers＇ perceptions of native and non-native teachers towards studying the effect of teachers＇ native language on learners＇ proficiency, accuracy, fluency, and achievement. To pave the way for these shifts, this study first reviews the theoretical perspectives and empirical findings concerning effective language teachers and then draws conclusions and implications which help interested stakeholders, i.e., supervisors, make informed decisions when they recruit language teachers.

Synthetic aperture radar imaging based on attributed scatter model using sparse recovery techniques

The sparse recovery algorithms formulate synthetic aperture radar （SAR） imaging problem in terms of sparse representation （SR） of a small number of strong scatters＇ positions among a much large number of potential scatters＇ positions, and provide an effective approach to improve the SAR image resolution. Based on the attributed scatter center model, several experiments were performed with different practical considerations to evaluate the performance of five representative SR techniques, namely, sparse Bayesian learning （SBL）, fast Bayesian matching pursuit （FBMP）, smoothed 10 norm method （SL0）, sparse reconstruction by separable approximation （SpaRSA）, fast iterative shrinkage-thresholding algorithm （FISTA）, and the parameter settings in five SR algorithms were discussed. In different situations, the performances of these algorithms were also discussed. Through the comparison of MSE and failure rate in each algorithm simulation, FBMP and SpaRSA are found suitable for dealing with problems in the SAR imaging based on attributed scattering center model. Although the SBL is time-consuming, it always get better performance when related to failure rate and high SNR.
