With the formation of Pakistan as a modern Islamic republic in 1947, the institutions of art and design education were transformed under the sway of modernization theories of development. A conceptual and physical infrastructure was put in place to modify existing institutions and to create new ones for encouraging modern art and artists in the country. The 1950s saw major developments taking place in the former Mayo School of Art which was upgraded to the National College of Arts to train designers, artists and architects to meet the requirements of a new nation. The distinction between arts and crafts formed the discourse through which the changes in art education were articulated. The process of change unleashed in art education is emblematic of the changes taking place in the other sectors of economy and culture. The Bauhaus influence which formed the initial impulse to bring artists and craftsmen in the service of national industry gave way to the competing fine art movements in painting resulting in abandoning the synthesis of arts and crafts envisaged in the earlier approaches to art education.  相似文献

Nonlinear solution of reinforced concrete structures, particularly complete load-deflection response, requires tracing of the equilibrium path and proper treatment of the limit and bifurcation points. In this regard, ordinary solution techniques lead to instability near the limit points and also have problems in case of snap-through and snap-back. Thus they fail to predict the complete load-displacement response. The arc-length method serves the purpose well in principle, Received wide acceptance in finite element analysis, and has been used extensively. However modifications to the basic idea are vital to meet the particular needs of the analysis. This paper reviews some of the recent developments of the method in the last two decades, with particular emphasis on nonlinear finite element analysis of reinforced concrete structures.  相似文献

Anatomy education in Pakistan is facing many of the same challenges as in other parts of the world. Roughly, a decade ago, all medical and dental colleges in Pakistan emphasized anatomy as a core basic discipline within a traditional medical science curriculum. Now institutions are adopting problem based learning (PBL) teaching philosophies, and since medical colleges in Pakistan first introduced PBL curricula that expose the basic sciences primarily in clinical contexts, the methods and extent of anatomy teaching have been topics of much debate. Many claim that PBL curricula dilute basic science education, especially anatomy. At the same time, classically trained faculty members with PhD in anatomy have become nearly extinct in Pakistan, with only four working in country. A third challenge currently facing anatomy education in Pakistan, as in many parts of the world, is an unavailability of cadavers for dissection. As more institutions adopt PBL curricula, as PhD anatomists are harder to find, and as cadavers for dissection become scarce, Pakistan and other countries around the world will have to seriously consider how they will sustain adequate anatomy education.

Research is an original and systematic investigation undertaken to discover new facts and information about a phenomenon. However a variety of empirical and ethical issues are on the rise in academia, especially plagiarism is quickly becoming part of global educational and research culture. More and more students and researchers are turning to the Internet for cooked solutions and shortcuts for writing assignments, research papers and thesis. The purpose of this paper is to highlight the seriousness of plagiarism amongst graduate and post graduate students of Pakistan. It also explores the university students’ level of awareness of plagiarism. A total of 365 graduate and post graduate students of randomly selected public and private sector universities participated in this exploratory empirical study. A self-reported questionnaire survey was used for collection of primary data. Findings revealed that there was a low level of awareness about plagiarism and university plagiarism policies and processes amongst the students. Findings also revealed that many respondents did not understand what plagiarism is? A significant number of students have fairly admitted that they have intentionally plagiarized written materials. Based on the findings of the study this paper puts forward recommendations to create awareness amongst the students regarding plagiarism, plagiarism policies and provides statistical evidences for formulation of policies and guidelines to combat plagiarism in institutions of higher learning in Pakistan. Furthermore, the paper submits recommendations to minimize the plagiarism based on the authors’ experiences.  相似文献

There is a good deal of consensus in the literature about the key role of leadership – especially that of the headteacher – in facilitating school improvement. Yet much of the research in this area has taken place in Western industrialised countries. This article explores the issue of headship in the context of schools in a specific developing country context, that of Pakistan. Drawing on 2 studies of the experience of headteachers in Karachi, the article identifies and explores the key variables that may contribute to a sense of personal efficacy for these heads, namely the expectations generated by the national or community culture, the powers and accountabilities generated by the school system in which they work, and their own individual personalities and histories.  相似文献

This study focused, for the first time, on the effect of ultrasonic features on the extraction efficiency of secondary metabolites in mustard seed cake(MSC). The nematostatic potential of sonicated seed cake was examined against the second-stage juveniles(J2 s) of root-knot nematode, Meloidogyne javanica. The results show that a 35 ppm(parts per million) concentration of a sonicated extract(SE) sample of MSC caused 65% J2 s mortality at 18 h exposure period in vitro. It also significantly suppressed the root-knot index(RKI=0.94) in tomato roots. The lethal concentration values for SE were 51.76, 29.79, and 13.34 ppm,respectively, at 6, 12, and 18 h of the exposure period, and the lethal concentration values for the non-sonicated extract(NSE)sample were 116.95, 76.38, and 55.59 ppm, respectively, at similar exposure time. Sinapine and gluconapin were identified as the major compounds in ultrasonic-assisted MSC. Because of the high extraction efficiency of metabolites in the SE, all treatments of SE were shown to be antagonistic to J2 s. Thus, this study of ultrasonication activity-based profiling of MSC may help generate target-based compounds at a scale relevant to the control of disease caused by nematodes in economic crops.  相似文献

In vitro cultures of loquat cultivar Mardan were established using shoot apices after treating with NaOCl (5%, 7%, 10%, 12%, 14% (v/v)) for 12 min and HgCl2 (0.01%, 0.05%, 0.10%, 0.20%, 0.25% (w/v)) for 2 min. A maximum survival rate of 70% was recorded after surface sterilization with 10% NaOCl. Caulogenic response was assessed on Murashige and Skoog (MS) medium fortified with assorted combinations of the cytokinins, benzylaminopurine (BAP), kinetin, and N6-(2-isopentyl)adenine (2iP). Treatment of BAP 1.5 mg/L combined with 2iP 9.0 mg/L and kinetin 1.5 mg/L was found to be optimum for shoot morphogenesis in terms of the number and subsequent growth of shoots, while the highest shoot length was yielded by the combination of BAP 0.5 mg/L, kinetin 0.5 mg/L, and 2iP 3 mg/L. Higher levels of cytokinins induced callogenesis, vitrification and stunted growth to some extent. For rhizogenesis, uniform sized micro-shoots were excised and transferred to half-strength MS medium containing auxins. The best rooting expression was observed with naphthaleneacetic acid (NAA) 1 mg/L combined with indole-3-butyric acid (IBA) 2 mg/L and paclobutrazol (PBZ) 1 mg/L.  相似文献

The present study aims to assess and compare the biochemical oxidative stress markers in male smokers and non-smokers with chronic periodontitis. One hundred thirty-four male chronic periodontitis patients and 64 apparently healthy male volunteers were recruited for the study. The periodontal status was evaluated by measuring gingival index, plaque index, papillary bleeding index and clinical attachment loss using UNC-15 probe. The biochemical markers estimated were total antioxidant capacity, RBC-superoxide dismutase, glutathione peroxidase, vitamin C, malondialdehyde and C-reactive protein. The obtained results indicate higher oxidative stress in chronic periodontitis. Smokers with chronic periodontitis show significantly higher periodontal clinical parameters and relatively higher systemic oxidative stress. Vitamin C estimation may be an important biochemical parameter in conjunction with clinical parameters for diagnosis of chronic periodontitis in smokers.  相似文献

Syzygium campanulatum Korth is a plant, which is a rich source of secondary metabolites (especially flavanones, chalcone, and triterpenoids). In our present study, three conventional solvent extraction (CSE) techniques and supercritical fluid extraction (SFE) techniques were performed to achieve a maximum recovery of two flavanones, chalcone, and two triterpenoids from S. campanulatum leaves. Furthermore, a Box-Behnken design was constructed for the SFE technique using pressure, temperature, and particle size as independent variables, and yields of crude extract, individual and total secondary metabolites as the dependent variables. In the CSE procedure, twenty extracts were produced using ten different solvents and three techniques (maceration, soxhletion, and reflux). An enriched extract of five secondary metabolites was collected using n-hexane:methanol (1:1) soxhletion. Using food-grade ethanol as a modifier, the SFE methods produced a higher recovery (25.5%?84.9%) of selected secondary metabolites as compared to the CSE techniques (0.92%?66.00%).  相似文献
