Early years education in Pakistan: trends,issues and strategies

This paper outlines the programme of provision of early childhood education and care (ECEC) which is currently urgently needed to support the development of children from birth to eight years in Pakistan. It begins by emphasizing the global recognition of the importance of such provision, before describing the recent history of ECEC in Pakistan, and the current situation. A case study from the pre‐primary (katchi) class in a typical government school is used to illustrate the urgent need for initiatives and action to implement both Education for All (EFA) commitments and government policy for ECEC. Impediments to the implementation of the policy, including financial, structural, organizational and cultural barriers are identified, and recommendations are made for overcoming these obstacles. From a human capital perspective, it is argued that an ECEC programme will benefit the country and its economy, as well as the individual children who will be enabled to become active and effective contributors to society.     

Establishment of engineering laboratories for undergraduate and postgraduate studies

The importance of the laboratories for the study of engineering problems is manifold. At the undergraduate level it provides an opportunity for the students to get an impression of the basic principles of engineering. At the postgraduate level it becomes an instrument for advanced level study and for the solutions to real-life engineering problems. Level of emphasis by an individual engineering institution on basic engineering, interdisciplinary aspects of engineering and relevance to international, national and local industrial trends effects the policy to establish the engineering laboratories. However, a core facility, for the teaching of the most basic principals of relevant field of engineering should be a common feature of all the laboratories associated with individual subject area. In this research paper an approach for establishing engineering laboratories is presented. It discusses the relation between the syllabus of appropriate level of study and the equipment required in the laboratory, physical planning for the laboratory, sequential and parallel approaches for establishing the laboratories, the functional capacity of laboratories, the organizational flexibility of the laboratories, the cost factor and the recurring expenditure. It suggests ways of utilizing the laboratory for effective teaching and research through optimal use of the above factors.     

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.     

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.     

Microbial control of diamondback moth, Plutella xylostella L.(Lepidoptera: Yponomeutidae) using bacteria (Xenorhabdus nematophila) and its metabolites from the entomopathogenic nematode Steinernema carpocapsae

Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension. The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests on foliage.     

Quantum-Inspired Blockchain-Based Cybersecurity: Securing Smart Edge Utilities in IoT-Based Smart Cities

Blockchain plays a vital task in cybersecurity. With the exerted efforts for realising large-scale quantum computers, most current cryptographic mechanisms may be hacked. Accordingly, we need a quantum tool utilised for designing blockchain frameworks to have the ability to be executed in the level of digital computers and resist the probable attacks from both digital and quantum computers. Quantum walks may be utilised as a quantum-inspired model for designing new cryptographic algorithms. In this paper, we present a new authentication and encryption protocol based on quantum-inspired quantum walks (QIQW). The proposed protocol is utilized to build a blockchain framework for secure data transmission among IoT devices. Instead of using classical cryptographic hash functions, quantum hash functions based on QIQW are employed for linking blocks of the chain. The main advantages of the presented framework are helping IoT nodes to effectively share their data with other nodes and full control of their records. Security analysis demonstrates that our proposed protocol can defend against message attack and impersonation attacks, thus ensuring secure transmission of data among IoT devices.
