In national perception, education is essentially for all. This is fundamental to all-round development, material and spiritual. It refines sensitivities and perceptions that contribute to national cohesion, a scientific temper and independence of mind and spirit--thus furthering the goals of socialism secularism and democracy enshrined in our constitution. The objective of the study focuses on achievement of children with learning disability in science. There are 5 null hypothesis tested in this research. The sample used in this study includes 35 children with learning disabilities in experimental group and 42 children with learning disabilities in control group. The different views taken on special education have ignited spark of controversies over segregating some children from the mainstream and providing them with extra opportunities. There are arguments for and against both special education and integrated education. Special education means the specifically designed instruction that meets the unusual needs of special children. It requires special materials, teaching, techniques, equipment and facilities. The design was an experimental research pre and post-test equivalent group. The research shows that there is no significant difference in all learning objective such as knowledge, comprehension and skill between control group and experimental group in the pre-test. This two sample groups also did not show any significant difference in the pre-test irrespective of gender, educational qualification of the teacher, years of experience of the teacher, parents＇ education, parents＇ profession, parents＇ income, type of management and type of school. On the other hand, for the post-test all the characteristics show that there are significant differences. This shows that there are effects on the treatment group in learning objective. Furthermore the experimental group showed significantly higher gain score than the control group with regard to the learning objective which comprises of knowledge, comprehension, application and skill.  相似文献   

A constrained linear quadratic optimization algorithm toward jerk-decoupling cartridge design     

Jun Ma  Si-Lu Chen  Chek Sing Teo  Chun Jeng Kong  Arthur Tay  Wei Lin  Abdullah Al Mamun 《Journal of The Franklin Institute》2017,354(1):479-500

Linear direct feed drives are widely used in machine tools, but an abrupt counter force from the secondary part will induce the jerk to the metro frame contacted with the linear motor and cause the vibration of auxiliary devices on it. The jerk-decoupling cartridge (JDC) provides a buffer to reduce such an impact. Design target for such a system includes both the tracking error and the jerk induced to the metro frame. To achieve both targets systematically, this work presents an integrated approach to efficiently determine parameters in the JDC and the position controller of the feed drive. The problem is firstly formulated as a nonlinear constrained optimization problem, which is then converted to a series of projection gradient optimization problems and step searching problems, which are either convex or linear. Thus, fast convergence of parameters are achieved within first several iterations. Through a series of simulation, the effectiveness of proposed methodology is verified.  相似文献

Opening Up Alternatives to Dominant Ideological Constructions of English Language Teaching in Malaysia     

Mohd Muzhafar Idrus  Habibah Ismail  Hazlina Abdullah  Hazleena Baharun  Noor Saazai Mat Saad  Ramiaida Darmi 《Changing English: An International Journal of English Teaching》2019,26(3):306-320

ABSTRACT

This paper investigates the impact of the Common European Framework of Reference for Languages (CEFR) on the way English language teaching (ELT) is currently understood and practised in Malaysia. It presents a critical discourse analysis of newspaper texts in order to show how CEFR represents a form of Western-imposed globalisation that conflicts with local cultures and values. We argue that the newspapers construct a dominant discourse that promotes a vision of society that accords with CEFR–ELT implementation. Our aim is to contribute to the development of a counter-discourse that challenges the broader world-view underpinning ELT.  相似文献   

Genetic basis of heterosis and inbreeding depression in rice (<Emphasis Type="Italic">Oryza sativa</Emphasis> L.)     

Alam?M.?F.?Email author  Khan?M.?R.  Nuruzzaman?M.  Parvez?S.  Swaraz?A.?M.  Alam?I.  Ahsan?N. 《浙江大学学报(A卷英文版)》2004,5(4):406-411

The genetic basis of heterosis was studied through mid-parent, standard variety and better parent for 11 quantitative traits in 17 parental lines and their 10 selected hybrids in rice (Oryza sativa L.). The characters were plant height. days to flag leaf initiation, days to first panicle initiation, days to 100% flowering, panicle length, flag leaf length. days to maturity, number of fertile spikelet/panicle, number of effective tillers/hill, grain yield/10-hill, and 1000-grain weight. In general the hybrids performed significantly better than the respective parents. Significant heterosis was observed for most of the studied characters. Among the 10 hybrids, four hybrids viz., 17A×45R, 25A×37R, 27A×39R, 31A×47R, and 35A×47R showed highest heterosis in 10-hill grain yield/10-hill. Inbreeding depression of F₂ progeny was also studied for 11 characters of 10 hybrids. Both positive and negative inbreeding depression were found in many crosses for the studied characters, but none was found significant. Selection of good parents was found to be the most important for developing high yielding hybrid rice varieties.

Early career researchers and their publishing and authorship practices          下载免费PDF全文

This study presents findings from the first year of the Harbingers research project, a 3‐year longitudinal study of early career researchers (ECRs), which sought to ascertain current and changing habits in scholarly communication. The study recruited 116 science and social science ECRs from seven countries who were subject to in‐depth interviews, and this paper reports on findings regarding publishing and authorship practices and attitudes. A major objective was to determine whether ECRs are taking the myriad opportunities proffered by new digital innovations, developing within the context of open science, open access, and social media, to publish their research. The main finding is that these opportunities are generally not taken because ECRs are constrained by convention and the precarious employment environment they inhabit and know what is best for them, which is to publish (in high impact factor journals) or perish.  相似文献   

Endophytes from medicinal plants and their potential for producing indole acetic acid,improving seed germination and mitigating oxidative stress     

Abdul Latif Khan  Syed Abdullah Gilani  Muhammad Waqas  Khadija Al-Hosni  Salima Al-Khiziri  Yoon-Ha Kim  Liaqat Ali  Sang-Mo Kang  Sajjad Asaf  Raheem Shahzad  Javid Hussain  In-Jung Lee  Ahmed Al-Harrasi 《Journal of Zhejiang University. Science. B》2017,18(2):125-137

Medicinal plants have been used by marginal communities to treat various ailments. However, the potential of endophytes within these bio-prospective medicinal plants remains unknown. The present study elucidates the endophytic diversity of medicinal plants (Caralluma acutangula, Rhazya stricta, and Moringa peregrina) and the endophyte role in seed growth and oxidative stress. Various organs of medicinal plants yielded ten endophytes, which were identified as Phoma sp. (6 isolates), Alternaria sp. (2), Bipolaris sp. (1), and Cladosporium sp. (1) based on 18S rDNA sequencing and phylogenetic analysis. The culture filtrates (CFs; 25%, 50%, and 100% concentrations) from these endophytes were tested against the growth of normal and dwarf mutant rice lines. Endophytic CF exhibited dose-dependent growth stimulation and suppression effects. CF (100%) of Phoma sp. significantly increased rice seed germination and growth compared to controls and other endophytes. This growth-promoting effect was due to the presence of indole acetic acid in endophytic CF. The gas chromatography/mass spectrometry (GC/MS) analysis showed the highest indole acetic acid content ((54.31±0.21) μmol/L) in Bipolaris sp. In addition, the isolate of Bipolaris sp. exhibited significantly higher radical scavenging and anti-lipid peroxidation activity than the other isolates. Bipolaris sp. and Phoma sp. also exhibited significantly higher flavonoid and phenolic contents. The medicinal plants exhibited the presence of bio-prospective endophytic strains, which could be used for the improvement of crop growth and the mitigation of oxidative stresses.  相似文献   

Politicization of bilateral aid and educational development in Pakistan     

Muhammad Ahsan 《Educational studies》2005,31(3):235-250

Increasing international cooperation and interdependence are important features of the contemporary globalized world. In the present age, foreign aid is a very peculiar type of transaction in the sense that its focus is to satisfy the objectives of the donor and the recipient, which are not always the same. This paper attempts to analyse the situation of US and British aid to Pakistan’s education sector. The role of international donors in the development of the education sector in Pakistan cannot be underestimated. They have been even more important for this developing country which has faced financial crises, particularly during the 1990s. These financial hardships faced by the country were mainly the outcome of the changed regional, political, as well as the geostrategic situation which also caused the change in the behaviour of international donors. It is especially true in the case of the USA and the UK where the aid to Pakistan was seriously affected by the changed situation in Afghanistan, political changes within the country, its nuclear programme and more recently the events of 9/11. This discussion reflects that the potential benefits of the aid were not reaped adequately due mainly to disruption and resumption of aid on the grounds of the geo‐political situation and strategic interests of donors.  相似文献
