一种在轨海上多运动舰船目标检测和跟踪方法     

矫腾章  胡玉新  吕鹏  张凯  台宪青 《中国科学院大学学报》2020,37(3):368-378

传统遥感卫星图像处理采用在地面进行目标检测和跟踪处理的模式，卫星将拍摄到的图像数据下传至地面数据处理中心，由地面数据处理系统对接收到的遥感图像数据进行目标检测和跟踪。然而，随着遥感图像分辨率的不断提高，需要下传的数据量增大，导致星地数据传输的时间大大增加，最终造成目标检测和跟踪的时效性降低。针对上述问题，提出一种基于多特征量判别的Canny边缘检测和联合概率数据关联的在轨海上多运动舰船目标检测和跟踪方法。将该方法利用中国科学院微小卫星创新研究院的高分微纳卫星实测数据在模拟星载的嵌入式开发平台上进行验证，结果表明该方法能够在轨对海上多运动舰船目标进行快速、准确的检测和跟踪。  相似文献   

Building strong foundations for educational achievement: Language assessments in early childhood education for deaf and hard of hearing children     

Patrick J. Graham  Elizabeth Shuler-Krause 《Psychology in the schools》2020,57(3):418-425

It is widely accepted that assessment plays a role in monitoring the development of young children with special needs in early intervention/early childhood settings. The process of assessing young children's language skills often looks for delays within a solid language foundation. However, many children who are deaf or hard of hearing (DHH) may not have a solid language foundation to assess, leading to inaccurate assessment. When we reframe how we assess language skills in children who are DHH, we ensure the assessment provides a comprehensive picture of the child's language development. It is important to modify language assessment tools where necessary while ensuring the assessment stays reliable and valid. It is critical to use multiple assessment tools to monitor the child's progress, including standardized assessments and assessment tools normed for DHH populations. Finally, it is crucial to monitor the child's skills in each language that they are using, regardless of which language is used most often. We explain why each of these factors needs to be considered in the assessment of young children who are DHH, will discuss the challenges of assessing this population, and will provide solutions to some of the challenges of assessing language skills in of young children who are DHH.  相似文献   

Sustaining What is Valuable: Contours of an Educational Language About Values     

LOVISA BERGDAHL  ELISABET LANGMANN 《Journal of Philosophy of Education》2020,54(5):1260-1277

Making liberal democratic values meaningful to study in schools is a more complex issue than being a question of turning values into explicit educational goals (Schleicher) or of curing a motivational deficit (Critchley). Since values seem to play an important role in the practices and commitments of people's everyday lives, values are calling for a continual refinement of our words in relation to the world (Laverty). The purpose of this article is to offer contours of an educational language about values that acknowledges this refinement and the pedagogical work that teachers might do—by way of language—in order to sustain the living-on of what is valued and valuable to us as individuals and as societies. To this end, the article is divided into two parts. The first part takes the temperature of the current political and educational debates, offering thereby a sociopolitical background to the need of a renewed language about values. Drawing on ordinary language philosophy (Moi, Murdoch and Forsberg) and the idea that there is an intimate relationship between how we look at the world (attention) and the words we use in describing it (language). The second part of the article places the emergence of values in a particular time in history before suggesting a more existential vocabulary about values for the purpose of teaching values in schools.  相似文献   

Towards a Model of Intercultural Communicative Competence in Iranian EFL Context: Testing the Role of International Posture,Ideal L2 Self,L2 Self-Confidence,and Metacognitive Strategies     

Ali Asghar Ghasemi  Hooshang Yazdani  Majid Amerian 《Journal of Intercultural Communication Research》2020,49(1):41-60

ABSTRACT

This study aimed to present a model of intercultural communicative competence (ICC) by incorporating international posture, motivational disposition (ideal L2 self), second language (L2) self-confidence, and metacognitive learning strategies. To this end, 150 Iranian L2 learners, selected through convenience sampling procedure, took part in the research. The findings of structural equation modelling revealed that the proposed model showed adequate fit to the data, implying that the model is appropriate in Iranian English as a foreign language (EFL) context. Also, the results indicated that learners with a high level of international posture are more likely to bridge the gap between their present and ideal selves. This was, additionally, argued that internationally oriented and ideally motivated learners become confident of their abilities to get engaged in interaction with L2 target communities. Furthermore, metacognitive learning strategies were found to be directly associated with ICC, implicating that the learners who continuously reflect on their learning and evaluate their performances are more prone to have a higher level of ICC. Finally, suggestions were offered for language teachers and policy-makers to inspire their learners to be more competent in communication with people of other cultures and languages.  相似文献   

Perfectionism and foreign language achievement: The mediating role of emotions and achievement goals     

《Studies in Educational Evaluation》2020

The purpose of the present study was to examine the role of perfectionism in the second/foreign language (L2) learning context. To this end, we investigated the possible links between perfectionism, emotions, achievement goals, and L2 achievement. A total number of 2008 secondary school students completed the relevant questionnaires. First, confirmatory factor analysis was performed to assure the construct validity of the questionnaires. Then, separate structural equation models were conducted to examine the relations among variables. Results indicated that adaptive perfectionism was directly related to positive emotions, while the opposite pattern was found for maladaptive perfectionism. Moreover, only adaptive perfectionism was related to mastery goals, and both adaptive and maladaptive perfectionisms were related to performance-approach goals and performance-avoidance goals. Maladaptive perfectionism dimensions were negatively related to L2 achievement, while one dimension of adaptive perfectionism had positive relation and another one had negative relation with L2 achievement. Finally, mediation analysis was performed and results showed that only negative emotions and only mastery goals could mediate the relation between perfectionism dimensions and L2 achievement.  相似文献

Word sense disambiguation based on context selection using knowledge-based word similarity     

Sunjae Kwon  Dongsuk Oh  Youngjoong Ko 《Information processing & management》2021,58(4):102551

In this paper, we introduce a novel knowledge-based word-sense disambiguation (WSD) system. In particular, the main goal of our research is to find an effective way to filter out unnecessary information by using word similarity. For this, we adopt two methods in our WSD system. First, we propose a novel encoding method for word vector representation by considering the graphical semantic relationships from the lexical knowledge bases, and the word vector representation is utilized to determine the word similarity in our WSD system. Second, we present an effective method for extracting the contextual words from a text for analyzing an ambiguous word based on word similarity. The results demonstrate that the suggested methods significantly enhance the baseline WSD performance in all corpora. In particular, the performance on nouns is similar to those of the state-of-the-art knowledge-based WSD models, and the performance on verbs surpasses that of the existing knowledge-based WSD models.  相似文献
