The burden of disease in patients with congestive heart failure is high. The future of BNP looks promising as it may be a better diagnostic tool for the diagnosis of CHF in developing countries in new millennium. Natriuretic peptide hormones, a family of vasoactive peptides with many favourable physiological properties, have emerged as important contenders for development of diagnostic tools and therapeutic agents in cardiovascular disease. Measurement of B-type natriuretic peptide has become as an easy-to-perform bedside test. The clinical and diagnostic significance of the measurement of plasma Nt-proBNP in the diseases of the cardiovascular system with particular emphasis on the assessment of patients with heart failure and their effects on predicting survival rate. The plasma levels of Nt-proBrain Natriuretic peptide responds more vigorously after myocardial infarction than those of other natriuretic peptides. This article is an attempt to give a short overview on the utility of BNP-blood levels for the diagnosis and treatment of heart failure  相似文献

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.  相似文献   

Library Anxiety among Undergraduate Students: A Comparative Study on Egypt and Saudi Arabia     

Ahmed Maher Khafaga Shehata  Mohammed Fathy Mahmoud Elgllab 《The Journal of Academic Librarianship》2019,45(4):386-393

The purpose of this paper is to report the findings of a study of library anxiety among a group of Arab students in Saudi Arabia and Egypt. The paper also investigated the factors that affect the students' level of anxiety while using academic libraries. The study tried to compare the difference in the level of anxiety in the two countries using a scale (LLPB) developed by the researchers which fit the culture in the Arab region. The study adopted a mixed methods approach. Semi-structured interviews were conducted with several students in Saudi Arabia and Egypt to determine the main factors that lead to having a level of anxiety in the libraries. In the second stage, a questionnaire was sent to students to measure what factors have a greater impact on the level of anxiety. The data showed that Egyptian students are more anxious about using the libraries than the Saudi students. The results also indicated that there is a need to train students on how to use the libraries and also change students' perception regarding the library to reduce the level of anxiety. This study was conducted in Egypt and Saudi Arabia the level of library anxiety and the factors that may affect the students may vary in other countries.  相似文献   

Exploring the role of a government authority in managing transformation in service re-engineering – Experiences from Dubai police     

Marwan Elnaghi  Sarmad N. Alshawi  Muhammad Mustafa Kamal  Vishanth Weerakkody  Zahir Irani 《Government Information Quarterly》2019,36(2):196-207

E-Government adoption and implementation has gained noticeable momentum across many developed and developing economies. Nevertheless, transitioning from the “electronic” to the stage of “transformational” domain – coined as t-Government – is posing the greatest challenge of how government services respond to changes in the broader economy and society. Despite considerable investments and the wide use of Information and Communications Technology (ICT), research literature on e-Government suggests that government services have yet to reach the full potential of seamless integration, where all transactions are completed electronically. Through a detailed analysis of the extant e-Government literature and a case study based empirical research, this paper explores the domain of e-Government in identifying the possible reasons for this potential shortfall in achieving full integration. Furthermore, the paper intends to highlight an aspect of complexity surrounding crossing the integration gap as the authors denote by “eChasm” in the e-Government conceptual model that leads to transformation. In addition, it focuses on radical change through Business Process Re-engineering (BPR) and the call for strategic style of leadership, for cross-agency collaboration leading to a successful realisation of transformational government (t-Government). It is interesting to note that researchers and public sector leaders have started to realise that implementing and managing the transformation of public services, copiously satisfying the users and stakeholders, is a task of multi-dimensional complexity.  相似文献   

Preschool Movement Education in Turkey: Perceptions of Preschool Administrators and Parents     

Serap Sevimli-Celik  Sadettin Kirazci  Mustafa Levent Ince 《Early Childhood Education Journal》2011,39(5):323-333

The purpose of this study was to examine the perceptions of preschool administrators and parents about preschool movement education and movement practices in preschools. Participants were 8 preschool administrators and 21 parents from 8 randomly selected private preschools in one of the municipalities in Ankara, Turkey. Semi-structured interviews, field visits, and observations were conducted, and written documents were collected. The findings indicate that preschool administrators and parents have limited content knowledge in movement education. Movement education practices were not aligned with physical-education goals for these schools. Children’s participation in organized sport activities is valued more as an extracurricular activity by administrators and parents. Limited indoor/outdoor spaces for movement activities seem to be among the limiting factors for movement education practices. To conclude, there is an immediate need to improve preschool administrators’ and parents’ knowledge of movement education and to enhance preschool facilities to ensure quality movement education.  相似文献

An exploration of Naquib al-Attas’ theory of Islamic education as ta’dīb as an ‘indigenous’ educational philosophy     

Farah Ahmed 《Educational Philosophy and Theory》2018,50(8):786-794

Abstract

This paper explores the ‘indigenous’ philosophy of education of Syed Muhammad Naquib al-Attas, a Malay-Muslim scholar who’s theoretical work culminated in the establishment of a counter-colonial higher education institution. Through presenting al-Attas’ life and philosophy and by exploring the arguments of his critics, I aim to shed light on the challenges and paradoxes faced by indigenous academics working at the interface of philosophy and education.  相似文献
