Research comparing the use of retrospective interviews (RIs) and think-aloud protocols (TAPs) as two data sources of writers’ composing processes is almost nonexistent. Trying to address this research gap, the present study examined the data obtained from the task-specific RIs and TAPs about the composing processes of 30 second language (L2) writers. Each participant thought aloud by concurrently verbalizing thoughts while performing an argumentative writing task, and then was interviewed immediately after the think-aloud session about their composing processes. The RI and TAP data was analyzed and compared in terms of five aspects of L2 writers’ composing: pre-writing stage, while-writing planning, first language (L1) use, composing problems and problem-solving, and text reviewing and changing. Though the results generally indicate that concurrent verbalizations provide much richer data than RIs about L2 writers’ composing processes, RIs were found to be a valuable source for revealing the ‘why’ of such processes. Besides, the gap between the data provided by the two sources differed from one composing aspect to another. Recommendations for how to optimally combine and make use of the two data sources in writing process research are provided. 相似文献

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

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

This article focuses on the critical ideologies of the curriculum behind the religious education (Madrassa system) and modern education systems (public and private schools) in Pakistan. These systems use different types of curriculum and have faced many challenges in the past, particularly with regard to the curriculum itself. Both systems of education teach students to develop their personalities in favor of their own system and against the other system. Religion plays a central role in the formation of the students' personality through both systems. Thus, both systems need religious literacy for the better use of religion in Pakistani society. 相似文献

This study examines the practice of information ethics of the members of the mailing group of the Pakistan Library Automation Group, called PAKLAGPK who participate frequently in the discussions on a variety of LIS ethical issues. The research uses both qualitative and quantitative methods, including a survey questionnaire to measure subscribers' prior knowledge about certain issues in Information Ethics (IE). The research also uses the content analysis method to investigate the information communication behavior of the subscribers over this mailing group. 相似文献

Electronic resources and services in Pakistani university libraries: A survey of users' satisfaction
Muhammad Sajid Mirza Khalid Mahmood 《International Information and Library Review》2012,44(3):123-131
This study is an attempt to evaluate the effectiveness of electronic resources and services in Pakistani university libraries on the basis of users' satisfaction. A survey method was employed to conduct the research. Using convenience sampling, eight university libraries; four each from Islamabad and Lahore including two from the public sector and two from the private sector having IT applications, were included in the users survey. The total population (i.e., 40,236) of library users was very large; therefore, a reasonable, manageable and convenient sample of 800 library users, including 100 users each from the eight libraries was selected. A semi structured questionnaire was designed to collect data, while a five-point Likert Scale from 1 (Dissatisfied) to 5 (Extremely satisfied) was used to measure the satisfaction level of the respondent. The study concluded that Pakistani university libraries are offering effective electronic resources and services to their users. 相似文献

INTRODUCTION Over the recent decades extensive research on atmospheric particles in urban environments was carried out. Most of the following papers refer to their authors’ contribution to air pollution and the effects on human health (Dzubay and Mamane, 1989; van Borm et al., 1989; 1990; Rojas et al., 1990; Paoletti et al., 1991; 1999; Al-Rajhi et al., 1996; McMurry et al., 1996; Querol et al., 1996; BéruBé et al., 1997; Esteve et al., 1997; Harrison et al., 1997; Zou and Hooper… 相似文献

This article highlights the research productivity and scholarly communication of library and information science professionals during 2003–2012 by using Web of Science databases from 40 library and information science core journals. Data was interpreted by using two open-source software Vantage point (powerful text-mining tool for discovering meaningful result from raw data) and CiteSpace II to visualize the library and information science growth and trends. Underlying results indicated that mainstream of authors (12,847, 69.9%) published their article as a single author from 2003–2009, this trend has declined and collaborative number of publications trend has inclined during the last 3 years. The University of Illinois at Urbana-Champaign produced 95 (0.52%) of the total publications and stands at the leading position. The maximum number of publications was carried out by universities rather than non-academic institutions. This article identified that Asian countries, such as China, Taiwan, India, and Iran, are still in its infancy stage. The present study could be considered as a useful tool for effective allocation of research funds in the research community and academic world of library and information science to enhance the research process. 相似文献
