The present study was conducted to investigate the oxidant–antioxidant status in iron deficient pregnant anemic women. One
hundred thirty pregnant women with iron deficiency anemia (IDA) were divided into three groups, namely mild (50), moderate
(50) and severe (30) anemic along with pregnant healthy women as controls (50). The complete blood count, plasma lipid peroxidation
products, enzymatic and non-enzymatic antioxidants were measured according to respective protocols. The levels of complete
blood count, iron, ferritin along with antioxidant enzymes namely catalase, superoxide dismutase, glutathione peroxidase,
glutathione reductase and reduced glutathione were significantly reduced in all IDA groups. However, the level of oxidized
glutathione, lipid peroxides, protein carbonyls, conjugated dienes were found significantly increased in all anemic patients.
Antioxidant vitamins, namely C, E and A were also found significantly decreased in IDA patients. On the basis of our results,
it may be concluded that IDA tends to increase the pro-oxidant components, which may result in various complications including
peroxidation of vital body molecules resulting in increased risk for pregnant women as well as fetus. 相似文献

Internationalization of higher education: Challenges, strategies, policies and programs 总被引:1,自引:0,他引:1

In today's changing world, the idea of internationalization of higher education especially in developing countries has been deduced from globalization of education process. The international aspect of higher education is becoming increasingly important, composite, and confusing. The higher education has an effect on the society through policy-making, funding, and planning. The purpose of this paper is to analyze the meaning, definition, importance, necessity, and pre-requisites of internationalization of higher education. This paper also studies the programs and strategies of internationalization of higher education. Key challenges for the future direction of internationalization are identified in this paper. 相似文献

In Iran, restructuring of medical education and the health care delivery system in 1985 resulted in a rapid shift from elite
to mass education, ultimately leading to an increase in the number of medical schools, faculties, and programs and as well
as some complications. This study aimed to investigate views on academic culture, values, and routines held by faculty members.
A nation-wide survey conducted in six public medical schools in Iran. The research findings show weak organizational culture
and values, together with routine behaviors sensed as a negative and low satisfaction with academic leadership. The research
evidence suggests bureaucracy, politicization, conservativeness, and centralization as common features of medical schools
in Iran and also suggests suitable supervisory skills to tackle the tension between governmental management and academic leadership
with cultural changes, the creation of new values, and adoption more efficient routines. 相似文献

The main goal of this study was to integrate gender and group effect into bridging strategy in order to assess the effect
of bridging analogy-based instruction on sophomore students’ misconceptions in Newton’s Third Law. Specifically, the authors
developed and benefited from anchoring analogy diagnostic test to merge the effect of group and gender into the strategy.
Newton’s third law misconception test, attitude scale toward Newton’s third law, and classroom observation checklists were
the other measuring tools utilized throughout this quasi-experimental study. The researchers also developed or used several
teaching/learning materials such as gender and group splitted concept diagrams, lesson plans, gender splitted frequency tables,
make sense scales, PowerPoint slides, flash cards, and demonstrations. The convenience sample of the study chosen from the
accessible population involved 308 students from two public universities. The results of multivariate analysis of covariance
indicated that the bridging strategy had a significant effect on students’ misconceptions in Newton’s third law whereas it
had no significant effect on students’ attitudes toward Newton’s third law. 相似文献

This paper presents the development of an Argument-Learning System (ALES). The idea is based on the AIF (argumentation interchange format) ontology using "Walton theory". ALES uses different mining techniques to manage a highly structured arguments repository. This repository was designed, developed and implemented by the authors. The aim is to extend the previous framework proposed by developing an intelligent tutoring environment for argument learning that aims to: (1) guide the students during argument learning; (2) aid in improving the students' argument skills; and (3) offer an argument classifier agent that retrieves the most relevant results to the subject of search. This paper focuses on the environment development specifying the status of each of the constituent modules. 相似文献

This paper explores entrepreneurial attributes among the students of The Islamia University of Bahawalpur, a public sector Pakistani university. Multistage sampling was employed to maximize the representation. Five hundred and twenty one master's level students from thirty departments returned completed questionnaires. Three factors emerged: self efficacy, efficiency and commitment, and entrepreneurial inclinations. The majority of the students exhibited positive entrepreneurial attributes. However, there was no significant difference between negative and positive entrepreneurial attributes. There was no significant impact of demographic variables such as gender, parental income and profession on entrepreneurial attributes. Impact on practice and policy is discussed. 相似文献

It is very important to develop student teachers' skills and knowledge during the pre-service teacher education process. In this study, the effectiveness of the approach in which student teachers' gained skills of developing and using TGMs (teacher-guided materials) based on integration of technology on physics education in STMC-Ⅱ (Special Teaching Methods Course-Ⅱ) for pre-service physics teachers was evaluated. The study was conducted with 33 physics student teachers in KTU (Karadeniz Technical University). Student teachers were required to develop and present TGMs, which were based on principles of special teaching approaches and techniques and integration of technology through instruction. The data of the study were gained from semi-structured interviews conducted with 14 student teachers, observations of the lessons conducted by each student teacher and document analysis of the student teachers' diaries collected during the term. The student teachers stated that STMC-11 was a very helpful experience to gain teaching skills. It is believed that all these activities, which are designed and performed in the classroom by student teachers during STMC-Ⅱ course, will not only prepare them for their teaching but also help them gain basic experiences that they will need in their future career. At the end of the process, it is concluded that all the student teachers gained nearly the whole defined aims--skills and knowledge of the STMC-Ⅱ. The implementation process should be organized very well to have advance of gaining many skills together. Key words: physics student teacher; STMC-Ⅱ; the skills of developing TGMs and integration of technology 相似文献

The paper details the findings of a study which focused on the analysis of the cultural representation of disability in school textbooks in Iran and England. The paper argues that whilst inclusive education could facilitate the incorporating of disabled pupils into mainstream schools, there needs to be deeper examination as to how this transition should take place for children aged 3–13. The paper suggests that in such examinations, school textbooks might be of significance in familiarising non-disabled pupils, teachers and authorities with the issues related to disability and disabled pupils. 相似文献
