Arabic documents that are available only in print continue to be ubiquitous and they can be scanned and subsequently OCR’ed to ease their retrieval. This paper explores the effect of context-based OCR correction on the effectiveness of retrieving Arabic OCR documents using different index terms. Different OCR correction techniques based on language modeling with different correction abilities were tested on real OCR and synthetic OCR degradation. Results show that the reduction of word error rates needs to pass a certain limit to get a noticeable effect on retrieval. If only moderate error reduction is available, then using short character n-gram for retrieval without error correction is not a bad strategy. Word-based correction in conjunction with language modeling had a statistically significant impact on retrieval even for character 3-grams, which are known to be among the best index terms for OCR degraded Arabic text. Further, using a sufficiently large language model for correction can minimize the need for morphologically sensitive error correction.

The lack of clear language in the Individuals with Disabilities Education Act (IDEA), which is the federal law that governs the provision of special education and related services to children with disabilities in the USA, has led to inconsistencies in school districts' decisions regarding the least restrictive environment (LRE). This uncertainty in determining an appropriate LRE has become a significant obstacle to educating students with disabilities. Therefore, this paper examines a number of court cases that have challenged school districts to provide the LRE for students with disabilities and have handed down decisions that define specific standards that are useful for school teams to implement the mandate of the LRE. Through the synthesis of these cases, the author provides criteria for determining the LRE for students with disabilities that could enhance inclusive education for these students. Finally, the author suggests that legislators should reconsider the language of LRE, make it more specific regarding the determination of LRE, and apply the standards defined in these cases and others to state a clear formula for developing LRE that could be utilised in school districts throughout the country.  相似文献

This article reports on the findings of an international online survey of early career researchers (ECRs) with regard to their authorship and peer review, attitudes, and practices, which sought to discover how the new wave of researchers were utilizing these key aspects of the scholarly communications system. A questionnaire was developed on the back of a 3‐year longitudinal, qualitative study and was distributed through publisher lists, social media networks, university networks, and specialist ECR membership organizations. Identical English, Polish, Russian, Chinese, Spanish, and French versions of the questionnaire were used. Results from 1,600 respondents demonstrated that 82.7% had co‐authored a paper, and most had performed a variety of authorship tasks. Almost half the respondents reported being subject to various authorship policies, although a quarter said they were not aware of any such policies. Almost all Chinese ECRs reported being subject to authorship policies, but only a third of UK ECRs reported the same. Three‐quarters of ECRs had experience in responding to peer review, and half had been peer reviewers. Half the respondents had a good experience of review and viewed it as a valuable way to improve their authorship skills. However, there was some criticism of some shortcoming such as lengthy peer review and superficial or uninformed comments by reviewers. Double‐blind review was the preferred methodology, and there were few suggestions for how to improve the review process.  相似文献

A study from the Harbingers research project provides a comprehensive assessment of the main features of the scholarly communications system as viewed by early career researchers (ECRs) in the final year of the study (2018). Aspects covered are: discovery and access, authorship practices, peer review, publishing strategies, open access publishing, open data, sharing, collaboration, social media, metrics, impact, reputation, libraries, publishers, and scholarly transformations. Nearly 120 science and social science researchers from seven countries were questioned about these 16 aspects. It was found that some scholarly features work well for ECRs, and in this category can be included: discovery and access, authorship practices, sharing, collaboration, and publishers. Reputation, publishing strategies, and impact are more problematical, and they, in turn, cause tensions regarding some other factors – social media, open access, and open data. Of the rest, libraries are largely invisible, and ECRs have conflicting views concerning ethical behaviour. Few envisage that transformational change will take place in the next 5 years.  相似文献

This study examined the relationship between Information Systems (IS) managers' formal education, level of technical and managerial training and their managerial effectiveness as perceived by their subordinates. The study finds that there is a strong positive relationship between the amount of technical training IS managers have received and their managerial effectiveness as perceived by their subordinates. There is also a significant relationship between IS managers' level of managerial training and their subordinates' perception of their managerial effectiveness. The managers' level of formal education was not found to have a significant relationship to the subordinates' perceived level of (their) managerial effectiveness. Finally, a regression model has been proposed to measure Information System managers'managerial effectiveness.  相似文献

This article provides the final results of a 3‐year study that sought to discover whether early career researchers (ECRs) were the harbingers of change with respect to scholarly communications. Over a hundred science and social science ECRs from seven countries, spanning three continents, were depth‐interviewed annually for 3 years (2016–2018) about their attitudes and behaviours with respect to 23 scholarly issues and activities (aspects). In order to provide an accessible overarching assessment of an extremely large and complex dataset, the interview data were categorized according to the strength and direction of change exhibited and the trends and points of interest raised. Results show that all ECRs have changed in one way or another, and a small minority has changed greatly in both attitude and practice and that collaboration and research impact are the scholarly aspects where most changes have occurred, and the greatest cause of change is not so much new technology as a change of jobs.  相似文献

The main function of Higher Educational Institutions (HEIs) is to produce skilled and knowledgeable workforce who are able to not only function with minimal guidance but also to contribute effectively to the hiring organizations. Many studies have indicated that most HEIs have somewhat similar course content and thrived at producing students with good academic achievement. But what differentiated them from one another is their ability to develop knowledge workers with the right employability skills or ??soft skills?? such as communication, problem-solving, interpersonal and other skills deemed important as the foundations by which they require to function at work regardless of the nature of employment. This paper reports findings of a large-scale study looking into the soft skills attainment of Malaysian HEI graduates. A quantitative survey design was employed whereby data were obtained through the administration of an instrument called the Malaysian Soft Skills Scale (My3S). My3S consists of 180 items covering seven elements namely Communications, Critical Thinking and Problem Solving, Teamwork, Moral and Professional Ethics, Leadership, Life Long Learning and Entrepreneurial aspects. The mean scores for the seven My3S subscales were found to be between 6.3 and 7.8 from the maximum possible score of 10. Specifically, comparisons were made between graduates of public and private institutions with respect to the seven elements. Findings of the study suggest that, in general, students of public HEIs scored higher in all seven skills. With respect to gender, male students scored higher than female students in all elements except for teamwork skills and moral and professional ethics. A comparison between fields of study showed that for both types of HEIs, technical students scored the highest in all skills except for moral and professional ethics. Based on the findings of this study, it is suggested that in addition to offering specific courses to improve soft skills attainment, HEIs need to embed soft skills in their academic curricula.  相似文献

A 30-item questionnaire was designed to determine Omani science teachers’ attitudes toward teaching science and whether or not these attitudes differ according to gender and teaching experiences of teachers. The questionnaire items were divided into 3 domains: classroom preparation, managing hands-on science, and development appropriateness. The questionnaire was administered to 139 randomly selected science teachers who teach science in grades 5–10. The sample consisted of 72 male teachers and 67 female teachers, 57 teachers with teaching experience between 1 and 5 years and 82 teachers with teaching experience of 6 and more years. The sample was selected from 7 schools in 1 Educational Governorate in the Sultanate of Oman. The questionnaire reliability was calculated by an internal consistency method, using Cronbach’s alpha, which gave the value of 0.73 for all the items. The findings indicated that science teachers’ attitudes toward teaching science were positive. Furthermore, the results showed that there were statically significant differences in teachers’ attitudes due to gender in favor of the female teachers and in teaching experience in favor of teachers with long experience. The study proposed some recommendations to improve the science teachers’ attitude, especially male teachers towards science teaching. Paying more attention to in-service professional development programs, encouraging new teachers to attend some classes to observe experienced colleagues, and finally rewarding teachers morally, socially, and financially are some of these recommendations.  相似文献

The medical and economic importance of ticks has long been recognized due to their ability to transmit diseases to humans and animals. Ticks cause great economic losses to livestock, and adversely affect livestock hosts in several ways. Loss of blood is a direct effect of ticks acting as potential vector for haemo-protozoa and helminth parasites. Blood sucking by large numbers of ticks causes reduction in live weight and anemia among domestic animals, while their bites also reduce the quality of hides. However, major losses caused by ticks are due to their ability to transmit protozoan, rickettsial and viral diseases of livestock, which are of great economic importance world-wide. There are quite a few methods for controlling ticks, but every method has certain shortcomings. The present review is focused on ticks importance and their control.  相似文献
