INTRODUCTION The Bibliotheca Alexandrina (BA) has develop- ed a workflow for turning printed books into digital books. The process starts with selection of books to be digitized, which is done mainly by BA’s Library Service Department. Books metadata is entered into the Digital Lab database. Metadata entry is followed by three core phases: scanning phase, in which the digital copy is generated; processing phase, in which image enhancement is performed; and OCR phase, in which text i…  相似文献   

Academic promotion in Malaysian public universities: a critical look at issues and challenges     

Norzaini Azman  Ibrahim Che Omar  Aida Suraya Md Yunus  Ahmad Nurulazam Md Zain 《牛津教育评论》2016,42(1):71-88

The expansion and transformation of Malaysian universities have generated major changes in the nature of academic employment and the structure of academic promotion in higher education institutions. These changes have considerable implications, in particular for the policy and practice of academic promotion in the public universities. We argue that despite sharing one common grade and salary system, distinct and significant differences exist in the academic promotion systems of the public universities. Drawing on one recent study on the academic promotion process in Malaysian public universities to contextualise our discussion, this paper highlights the complexity in the promotion process in these institutions. It also discusses and articulates the attendant issues and challenging aspects of the academic promotion process. We argue that the interrelated issues and challenges, and certain academic practices and habits stemming from the pressure to gain a promotion are pervasive, and that they affect the academic value system and work culture. We conclude by asserting the importance of applying a consistent standard for promotion within a single salary system and that the academic promotion system in the public universities should ultimately affirm and communicate core academic values, and also aim at obtaining evidence of excellent accomplishments.  相似文献   

Progressive education and the case of a bilingual Palestinian-Arab and Jewish co-existence school in Israel     

Khalid Arar  Asmahan Massry-Herzalah 《School Leadership & Management》2017,37(1-2):38-60

The purpose of this paper is to exemplify a ‘grass-roots’ change based on Dewey's experimental progressive education model employed in the ‘Bridge over the Valley’ bilingual school, a Palestinian-Arab and Jewish school in Israel. In order to identify the progressive ‘approach' underlying this change, the ‘method' that guided the implementation of a bilingual school, it's evaluation and then its dissemination to other schools, we used a qualitative case study method to understand whether John Dewey’s theory of education for peace was able to effect change in Palestinian-Arab and Jewish school education in Israel. The case findings describes the use of the progressive approach of education for peace in the ‘Bridge over the Valley’ bilingual school, as it is expressed in the school’s pedagogy, the implementation of the progressive method and in the accompanying discourse. Reciprocal teacher–child relations are considered an important factor to create fertile conditions for learning. The case findings contribute to our introduction of democratic education in a spatial reality. Underlying this approach stood a pedagogical method and conceptualization for conflict resolution and the opening of a space for empowering dialog for co-existence.  相似文献   

Validity of acute phase proteins and trace metals as adjuncts in viral hepatitis A and B     

Saad A. Noeman  Kommajosyula Sharada  Hassan El-Bena  Samia EL Dardery  Khalid AL Sawaf 《Indian journal of clinical biochemistry : IJCB》1994,9(1):40-42

The level of seven acute phase proteins was estimated together with copper and zinc in two groups of 15 children each suffering from hepatitis A (HAV) or Hepatitis B (HBV). The mean concentration of α-1 antitrypsin, α-2 macroglobulin, ceruloplasmin, C3 and copper was increased uniformly in both the types of viral hepatitis. α-1 acid glycoprotein, haptoglobin and zinc levels were decreased in both the infections. A significant decrease in albumin level was observed in HAV while the decrease was not significant in HBV. All the paramenters were repeated after one month on the day of discharge following the disappearance of clinical signs and symptoms wherein the haptoglobin level returned to normal in HAV. No change was observed in the level of other acute phase proteins. The level of the trace elements returned to normal. The observed increase in the levels of acute phase proteins at the onset does not seem to have any significant relation to the subsequent course of the disease. However, the level of acute phase proteins and other biochemical parameters may indicate a delayed biochemical recovery phase in conjunction with the underlying hepatic pathological changes in the course of viral hepatitis in spite of clinical recovery.  相似文献   

Dissection videos do not improve anatomy examination scores     

Mahmud W  Hyder O  Butt J  Aftab A 《Anatomical sciences education》2011,4(1):16-21

In this quasi-experimental study, we describe the effect of showing dissection videos on first-year medical students' performance in terms of test scores during a gross anatomy course. We also surveyed students' perception regarding the showing of dissection videos. Two hundred eighty-seven first-year medical students at Rawalpindi Medical College in Pakistan, divided into two groups, dissected one limb in first term and switched over to the other limb in the second term. During the second term, instruction was supplemented by dissection videos. Second-term anatomy examination marks were compared with first-term scores and with results from first-year medical students in previous years. Multiple linear regression analysis was performed, with term scores (continuous, 0-200) as the dependent variable. Students shown dissection videos scored 1.26 marks higher than those not shown. The relationship was not statistically significant (95% CI: -1.11, 3.70; P = 0.314). Ninety-three percent of students favored regular inclusion of dissection videos in curriculum, and 50% termed it the best source for learning gross anatomy. Seventy-six percent of students did not perform regular cadaver dissection. The most frequent reason cited for not performing regular dissection was high student-cadaver ratio. Dissection videos did not improve performance on final examination scores; however, students favored their use.  相似文献

Simple operated multipurpose temperature control cryostat     

ABBAS T.A. OMAR M.S. 《浙江大学学报(A卷英文版)》2007,8(5):793-796

A suitable simple optical cryostat for optical, magneto-optical, electrical and thermo-electrical measurements was designed. It is suitable for use in a magnetic pool gap as narrow as less than 1 cm. Throughout a long period of time, the heat diffusion process of the cryostat can be easily operated at slow increase in sample temperature in a range 1.25 K/min at 200 K that will be reduced gradually to 0.66 K at room temperature. Liquid nitrogen was used to cool down the temperature. During the operation, the change in the measured energy gap of a semiconductor sample and other physical parameters resulting from the change of temperature can be corrected through the temperature coefficient of that parameter at the corresponding temperature. The cryostat was successfully used for all experiments mentioned above to measure the properties of a single crystal of GaP (Gallium Phosphate) semiconductor.  相似文献

INTRODUCTION Rice (Oryza sativa L.) is one of the most im-portant crops in Pakistan. It is the third largest crop interms of area and production after wheat and cotton.Although rice in Pakistan is consuming large acreage,Pakistan is still far behind other rice producingcountries. The average yield is very low (2 t/ha) ascompared to Egypt (8.4 t/ha) and USA (6.6 t/ha).There are many reasons for this low yield. The mostimportant are high temperature (40?50 °C), low hu-midity at …  相似文献   

Motivation to teach: the case of Arab teachers in Israel     

Khalid Husny Arar  Asmahan Massry-Herzllah 《Educational studies》2016,42(1):19-35

This paper describes an attempt to identify factors influencing teachers’ motivation in the Arab education system. In-depth interviews with 10 school principals, 15 teachers and 3 counsellors, yielded three themes influencing Arab teachers’ motivation: (1) Arab culture, (2) the school climate and (3) government policies. Arab teachers try to meet both government requirements and the minority Arab society’s expectations that they will shape students’ academic achievements, national identity and culture. Deficient resources and Arab principals’ detached management styles augment the difficulty, negatively influencing teachers’ motivation. Suggestions are given to improve government policies and Arab principals’ work and thus to enhance teachers’ motivation.  相似文献
