Sino-US English Teaching 2014年第8期11卷 567-575页

作者： naqvi Naj am Abbas Rida batool Institute of Space Technology Islamabad PakistanNorthwestern Polytechnical University Xi'an China Northwestern Polytechnical University Xi'an China

This research venture investigates the trends and motives behind the English learning as a second language. The author has used the Chinese binoculars to probe into the phenomenon of English learning and teaching. English language has become an international tool of communication and business. Professional and students at China's Mainland have been learning English since long but this trend has been increased in the recent years due to the wave of globalization and also owing to the enormous emerging economy of China. Internationalization of education and the quest of knowing the culture and civilizations have spurred the need for English learning. The authors have performed a questionnaire based research with the sample of 130 university students learning Chinese at different English learning institutes at Xi＇an, Shanxi, China. The analysis of the findings in this research highlights the reasons behind the growing trends of English learning and also describes the teaching methodology for effective language teaching in the Chinese perspective.

Evaluation of glacial resource potential for sustaining kuhl irrigation system under changing climate in the Himalayan region

引用

Journal of Mountain Science 2019年第5期16卷 1150-1159页

作者： Arshad ASHRAF Adeela batool Climate Energy and Water Research Institute National Agricultural Research Center (NARC)

A large numbers of mountain communities in the Himalayan region depend on glacier-fed kuhl system – gravity flow irrigation, for their sustenance. The depletion and retreat of glaciers often result in disruption of melt flows to kuhl system, which ultimately impacts the agriculture as well as livelihood of the local communities. Sustainability of glacial resource was assessed for establishing kuhl irrigation system based on indices of glacier decrease by number(GDN) and glacier depletion by volume(GDV) during the 2001-2013 period. The selected factors are important in terms of understanding point source and reserve potential of glaciers for sustaining glacier-fed kuhl irrigation in this region. The sustainability of glaciers was found good(i.e. a least decrease or rather increase in glacier number and volume) in about 23.6% glaciers(ice reserves about 705.9 km^3) under >10 km^2 area class of glaciers mainly in Gilgit and Shigar river basins of the Karakoram range. In the 5–10 km^2 class of glaciers, sustainability was good in 49 glaciers(ice reserve 26.59 km^3) and under 1–5 km^2 class, in 558 glaciers(ice reserve 60.189 km^3). Overall sustainability of glaciers appears to prevail in the Karakoram basins. The lesser sustainability of glaciers in the Himalaya basins like Astore and Jhelum would apparently be compensated by monsoon and change in rainfall pattern. A regular monitoring of the glacier resource and utilizing advance water conservation techniques would help in coping with negative impacts of downwasting of glaciers and provide long-term support to kuhl irrigation system in the Himalayan region in future.

Background: A cross sectional comparative study was conducted in a well populated city named Rawalpindi, which is located in the Northern part of Pakistan. Objectives: This study was aimed to document the comparison of menopausal-related symptoms among educated and non educated women of Rawalpindi, Pakistan. Methods: MRS was used to measure the intensity of menopausal symptoms. 100 educated and 100 uneducated women were selected for study purpose. Pakistan Institute of Medical Sciences, Military Hospital and Combined Military Hospital were selected as a study setting. Findings: Correlation & Fisher exact test was applied for statistical analysis. The intensity of symptoms reported by Educated women as: sleeping problems (93.0%);heart discomfort (80.0%);hot flushes and sweating (70.0%);joint and muscular pain (52.0);depressive mood (63.0%);irritability (42%);anxiety (60.0%). physical and mental exhaustion;(48.0%);sexual problem (61.0%);dryness of vagina (57.0%);and bladder problem (65.0%). The severity of symptoms in uneducated women;sleeping problems (77.0%);heart discomfort (73.0%);hot flushes (69.0%);joint and muscular pain (66.0);depressive mood (71.0%);irritability (58%);anxiety (80.0%). physical and mental exhaustion (70.0%);sexual problem (66.0%);dryness of vagina (70.0%);and bladder problem (83.0%). Conclusions: Somatic symptoms were high in educated women as compare to uneducated women while the prevalence of psychological and Urogenital symptoms were high in uneducated women as compare to educated women.

Exploring Critical Thinking Dispositions among Fourth Year BSc Nursing Students of Various Colleges of Nursing, Pakistan

引用

Open Journal of Nursing 2024年第6期14卷 267-281页

作者： Sadaf Younis Najma Balquees Anwar syeda Fakhar batool College of Nursing Combined Military Hospital Quetta Pakistan

Background: Critical Thinking (CT) dispositions in nursing are prominent predictors of competence in delivering high-quality care, and of professionalism, in newly graduated nurses. CT skills, in isolation of CT dispositions, do not guarantee success in the workplace, because Critical Thinking Dispositions (CTD) are important elements of intellectual reasoning that simulate a person towards using the CT skills. Therefore, nursing educational programs should promote lifelong learning rather than focusing on transferring the content of nursing knowledge only. And for this purpose, quality education is the key. Education should focus on teaching from diverse perspectives, incorporating various teaching learning strategies that are congruent with the modern era. Purpose: The purpose of this study is to explore critical thinking dispositions among final year Baccalaureate Nursing students of various military colleges of nursing, in Pakistan. Methodology: A descriptive qualitative exploratory study design was used to investigate the CTD of BSc final year nursing students. The study population included twelve willing nursing students, from six military colleges across the country. Demographic information and consent was taken from the participants of the study. In-depth interviews, through a semi structured interview guide, and probes were used to obtain data related to personal experiences of CTD amongst the nursing students. Results: Data analysis showed two broad themes: 1) Perceptions of CT, and 2) Experiences of CT dispositions. In theme one, the emerging category was: Clarity of CT;whereas in theme two, the categories that emerged were: a) Truth Seeking, b) Open Mindedness, c) Inquisitiveness, and d) Self Organization. Conclusion: The findings of the study revealed positive dispositions towards truth seeking, open mindedness, and self-organization, whereas disposition towards inquisitiveness was weak. Self-confidence and maturity also emerged as positive factors that
