Effect of seedling age and water depth on morphological and physiological aspects of transplanted rice under high temperature

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 …     

A Study of the Causes of User Dissatisfaction in Academic Libraries: A Case of University Students in a Developing Country

ABSTRACT

This article investigates students’ perceptions and expectations of service quality to understand the causes of dissatisfaction with the services delivered by the university libraries in Bangladesh. A total of 623 usable responses were collected from ten public and private university libraries in the country. The survey data were collected using a modified five dimensional SERVQUAL-based questionnaire, consisting of 26 service items. To determine the level of user satisfaction/dissatisfaction with the service items, the study used the disconfirmation theory with slight modification. It was found that users’ unrealistically high expectation for quality services is one of the key sources of their dissatisfaction. The other causes of dissatisfaction include lack of user-employee relationships, lack of attention to users’ needs, an external communication gap between library and users, lack of attention to enhance staffs’ performance, etc. Based on the service deficiencies identified, the study offers some measures that could be used as a way to improve service quality, and thereby user satisfaction.     

Mining movies for song sequences with video based music genre identification system

Musical sequences with actors dancing and lip-synching to songs sung by playback singers are integral parts, particularly of South Asian movies. Fans seek out movies for their songs and they often seek songs of a particular genre. In fact, song and dance sequence of South Asian movies are an industry of their own. Given the huge numbers of movies produced in South Asia over the past decades, most of which are in digital archives, it is an important problem to automatically extract and categorise their musical sequences. This paper proposes a system for musical sequences extraction from movies. Our method invokes an SVM-based classifier and makes as well a novel application of probabilistic timed automaton to distinguish musical sequences from non-musical. Our system analyses both audio and video signals to give a classifier that not only extracts musical sequences from movies but identifies their genre. We achieved a recall of 93.24% with precision of 87.34% in song extraction when applied on 10 popular Bollywood movies. An accuracy of 89.5% has been achieved on Bollywood song genre identification.     

Variations in perceptions of the learning environment and approaches to studying among university students in Pakistan

In Western countries, university students adopt various approaches to studying depending on how they perceive their learning environment. Their perceptions and approaches are related to demographic and contextual factors such as age, subject of study, gender, and year of study. This study looked for similar relationships in Pakistani students. A survey, administered to 494 male and 418 female undergraduates in four subject areas across four years of study at two universities in Pakistan, addressed their perceptions of the learning environment, learning preferences, motivation, and approaches to studying. Consistent with Western research, students in the arts and social sciences perceived their programmes more positively and were more likely to adopt a deep approach to studying, compared to students in science and technology or business and management. Contrary to Western research, students’ perceptions of their learning environment varied with age and year of study, but their approaches to studying did not. Gender differences were found in their perceptions and motivation. These variations appear to be specific to the context of Pakistan.     

Critical considerations for planning and implementing a CALL program

The field of Computer Assisted Language Learning （CALL） has transformed dramatically--from the days of the behaviourist approach that dominated CALL in the 1970s to the dynamism of Interactive approach in the 1990s under the immense influence of information communication technology （ICT）. Regardless of these periodic changes and improvements, successful implementation of CALL programs in schools decisively hinges on critical assessment and decisions that are undertaken by schools. As such, the responsibility of the technology adopters in this respect must reflect school＇s aspirations and understandably, students＇ abilities, interests and needs This paper attempts to clarify these issues through a case study of implementation of CALL in an urban secondary school in Malaysia. The outcome of the case study establishes critical considerations that need to be arbitrated to successfully implement CALL programs for English language teaching （ELT） at the school level.     

Perceived service quality-loyalty path: A PAKSERV based investigation of international students enrolled in business schools in Thailand

We aim to examine the international student perceived service quality of Business Schools located in Thailand to link it with their intentions to remain loyal. The survey based approach is adopted to collect data from 300 international students enrolled in various business schools in Thailand. All the dimensions of PAKSERV except Personalization are found to positively contribute to student satisfaction, which strongly leads to their loyalty to business schools. This is the first study which validates the PAKSERV scale in a business school context while collecting data from international students – investigating their perceptions of service quality to link it to their loyalty to business schools. The findings call for investment in faculty and process development to improve the international student perceptions of business schools located in Thailand. The findings will help Thai higher education policymakers specifically to improve student perceived service quality in order to attract and retain international students.     

An analysis of the social impact of the stipend program for secondary school girls of Khyber Pakhtunkhwa

The present study carries out an impact analysis of a conditional cash transfer (CCT) program for secondary-school girls in seven districts of Khyber Pakhtunkhwa province in Pakistan, including Battagram, Bonair, Hangu, Kohistan, Shangla, Tank, and Upper Dir. In 2012 we collected household-level primary data and used a probit model for quantitative analysis. Further, we conducted various focus group discussions and key informant interviews in the target areas. Results show that the chances of female schooling decrease with a rise in family size. The chances of female education increase by 1.8 and by 3.3 % if household heads and their spouses have one additional year of schooling, respectively. Better educational services and rises in family income increase the chances of female ecucation by 11 and 0.3 %, respectively. Finally, socioeconomic awareness, improved economic conditions, and CCTs increase the chances of female education by 5.2, 4.7, and 0.03 %, respectively. Overall, the stipend program (CCTs) shows a pareto improvement. Our results indicate that 35 % of girls will drop out in the absence of a stipend program. The present study recommends that to increase program effectiveness, local-level monitoring and program evaluation may be improved, delays in stipend payments to female students should be reduced, a grievance redressal mechanism for parents and guardians should be introduced, and clear synergies should be developed with other transfer programs.     

The social background of Makerere University students and the potential for cost sharing

The social background of Makerere students was analysed in order to gain some insight in the distribution of scarce higher education opportunities in Uganda and assess the ability of the students to finance part of their education cost in the process of massifying higher education without diluting the quality of instruction. The findings were that students from well to-do learned families in the more prosperous districts were enjoying the existing performance based subsidies (PBS) and the privately sponsored places and programs (PSPP) which Makerere University had introduced. The interaction of the social and school system acted to reinforce the inequalities at all stages starting from family background, the primary and secondary schools as well as the universities under the present PBS system of admission.The study recommends that while government must remain with the primary responsibility to fund higher education, the public subsidy should become more sensitive to equity and if need be introduced to cost sharing with capacity for positive discrimination. In order to implement this, the existing PBS should gradually be replaced by an equity based subsidy (EBS) starting with 50% of the funds. The funds for EBS should be allocated to the districts which should develop capacity for identification of the most needy students to get the EBS awards. Students from low income families should compete for both PBS at national level and EBS at their district levels. A loan scheme is also recommended for students who may not be sponsored under PBS and EBS as well as for living expenses which should be assumed by the beneficiaries.     

What is an objective structured practical examination in anatomy?

Assessing teaching‐learning outcomes in anatomical knowledge is a complex task that requires the evaluation of multiple domains: theoretical, practical, and clinical knowledge. In general, theoretical knowledge is tested by a written examination system constituted by multiple choice questions (MCQs) and/or short answer questions (SAQ). The assessment of practical knowledge (three‐dimensional anatomical concepts) involves oral, spot, or objective structured practical examinations (OSPE). Finally, the application of anatomical knowledge to patients is tested mainly through objective structured clinical examinations (OSCE). The major focus of this study is the OSPE. Although many schools challenge students using this tool in practical examinations in the early phase of the curriculum, the true meaning of OSPE is frequently forgotten and it becomes, in reality, a spot examination. This article, for the first time, describes how the concept of the OSPE has evolved and is currently being used to assess the practical domain of anatomical knowledge in a problem‐based curriculum at Alfaisal University College of Medicine. In addition, it describes the main differences from the spot examination, which is normally used in traditional medical curricula. The authors believe that the OSPE remains the most efficient tool to assess the practical aspects of anatomical knowledge in a system where basic knowledge is integrated with the clinical or functional part of anatomy. However, this contention only holds true if the OSPE process revolves around structured objectives. Anat Sci Educ 6: 125–133. © 2012 American Association of Anatomists.     

Relationships of Some Personality Variables to Academic Attainment of Secondary School Pupils

The study examined the relationship of extraversion (E), neuroticism (N), psychoticism (P), academic self‐concept and locus of control to academic attainment of lower secondary school pupils in a cross‐cultural context. Measures of E, N, P, academic self‐concept, locus of control and academic attainment were taken from 120 pupils (60 boys, 60 girls) of Standard 7 in a middle school in Bophuthatswana (Southern African region). The analysis of results revealed that E, N and P are significantly negatively related to academic attainment, while academic self‐concept and internality are significantly positively associated with measures of academic attainment. No significant sex differences were found. It was also observed that mean E and N scores of the subjects of this study were significantly lower than those given in Eysenck and Eysenck's (1975) normative data for English children of the same age.
