The worldly space: the digital university in network time

Abstract

This article considers the effect of information technology upon teaching, learning and research in the ‘digital university’. In less than a generation the university has become a business like any other. It does so in the determining context of neoliberal globalisation and the computer revolution. The university develops through what we may now see as a disastrous ‘category error’. The article argues that humans are analogue creatures who have constructed analogue worlds that they recognise in large measure, in nature. Digital logic is nowhere recognised in nature, and is ultimately alien to us. The university is the key institution for enabling us to understand who and what we are, yet it is being undermined through the suffusion of the market logic and the digital technologies that drive it from a past we look to less, to a present we dwell in more, and a future we are less able to shape.     

Anatomy education environment measurement inventory: A valid tool to measure the anatomy learning environment

Students' perceptions of the education environment influence their learning. Ever since the major medical curriculum reform, anatomy education has undergone several changes in terms of its curriculum, teaching modalities, learning resources, and assessment methods. By measuring students' perceptions concerning anatomy education environment, valuable information can be obtained to facilitate improvements in teaching and learning. Hence, it is important to use a valid inventory that specifically measures attributes of the anatomy education environment. In this study, a new 11‐factor, 132‐items Anatomy Education Environment Measurement Inventory (AEEMI) was developed using Delphi technique and was validated in a Malaysian public medical school. The inventory was found to have satisfactory content evidence (scale‐level content validity index [total] = 0.646); good response process evidence (scale‐level face validity index [total] = 0.867); and acceptable to high internal consistency, with the Raykov composite reliability estimates of the six factors are in the range of 0.604–0.876. The best fit model of the AEEMI is achieved with six domains and 25 items (X² = 415.67, P < 0.001, ChiSq/df = 1.63, RMSEA = 0.045, GFI = 0.905, CFI = 0.937, NFI = 0.854, TLI = 0.926). Hence, AEEMI was proven to have good psychometric properties, and thus could be used to measure the anatomy education environment in Malaysia. A concerted collaboration should be initiated toward developing a valid universal tool that, using the methods outlined in this study, measures the anatomy education environment across different institutions and countries.

自20世纪60年代以来，伊朗高等教育面临着一系列的问题。总体上讲，在这一阶段面临的主要问题是缺少合格的教学人员，同时也无能力为不合格的教师提供足够的师资培训课程，院校缺少先进的教学资源，并面临着学生人数日益聚增的巨大压力。在这种条件下，伊朗高等教育部组织了综合性调查，探索了建立远程教育机构的可行性，其目的在于为边远和教育不发达地区的国家企事业人员提供新的服务。 新建立的远程教育大学主要面向成人学习者，它为促进伊朗的高等教育起到了重要作用。在这之前，没有一所高等院校能够满足成年人的学习需求。正是由于此…     

Educational governance and challenges to universities in the Arabian Gulf region

Higher education institutions in the Arabian Gulf region today, which have mushroomed and proliferated in the past ten to fifteen years, have been constructing themselves along models of Western universities at the levels of governance, programs, and structure. At the outset of the twenty-first century, universities have globally experienced a drastic shift in their governance from ‘republics of scholars’ to stakeholder organizations. In this paper, we discuss and deconstruct some of the consequences of that drastic shift, paramount among which is the downsizing and neglect of some sciences/fields. We discuss some of the major problems that the Market Model of the University is facing in the West through a literature review. We also explore the academic view on some problems and challenges facing University governance today in the globe at large and specifically in the Arabian Gulf Region. We believe that universities in this region in their present state face the serious challenge of generating indigenous knowledge that fulfills the needs of citizens within this region, knowledge that draws upon the culture, history, and geography of the area and responds to the specific needs of citizens in this area.     

Building Child Friendly Cities in the MENA region

The notion of Child Friendly Cities (CFCs) was first developed during the Second United Nations Conference on Human Settlements (HABITAT II), held in Istanbul in 1996. The concept is based on four general principles of the United Nations Convention on the rights of the child: (1) fair treatment of every child, regardless of ethnicity, gender, religion, socioeconomic background etc.; (2) top priority of the best interests of the child; (3) the child’s right to a better life and development; and (4) respect of children’s views. In a CFC, children are encouraged to take part in the decision making processes that affect their lives. Instead of starting yet another programme for children, the development of a CFC mobilises and connects existing agencies and actors. Giving examples of some cities in the Middle East and North Africa (MENA) region, this paper demonstrates that building CFCs has induced the development of mechanisms and structures which have enabled cities to address children’s issues in a systematic manner. These mechanisms and structures include: a municipal child-friendly legal framework, local development councils and NGO networks and local municipal development offices. The author argues that in building CFCs, the role of municipal authorities is indispensable in responding to the needs of children and young people within the municipalities’ mandates.     

Adaptive threshold to guarantee both detection and false alarm probabilities in multi-taper based spectrum sensing

The multi-taper spectrum (MTS) estimator enjoys a relatively low computational complexity and high estimation accuracy making it an attractive method for spectrum sensing in cognitive radio (CR) networks. However, it is difficult to guarantee both detection and false alarm probabilities when its design is based on fixed threshold, especially when the noise power fluctuates due to channel conditions. In this paper, a new adaptive threshold method to guarantee both detection and false alarm probabilities for MTS based spectrum sensing is proposed. By means of estimating noise power and signal power, the decision of adaptive threshold is able to adapt the noise fluctuation and achieve efficient trade-off between detection and false alarm probabilities. A closed form expression for the adaptive threshold is derived for both additive white Gaussian noise (AWGN) channel and multipath fading channel. Several metrics are employed to compare the performance of the proposed adaptive threshold method with that of the fixed threshold methods such as: error decision probability, detection probability, false alarm probability and throughput. The obtained results show that the proposed method achieves better spectrum efficiency and high throughput in comparison with the conventional fixed and adaptive threshold methods presented in the literature.     

A new approach for constrained chaos synchronization with application to secure data communication

In this paper, a new technique is introduced for chaos secure data communication. In this approach, in addition to the usually used techniques for data encryption, the concept of carrier encryption is introduced to increase the security level of the secure communication scheme. To fulfill this objective, at the transmitting end, two chaotic oscillators are coupled, and a set of inequality time dependent constraints with time dependent bounds is imposed on the generated chaotic signals. Moreover, to increase system complexity and its security level, the imposed set of constraints and their bounds are allowed to be changeable from one time period to another during the transmission process. As a result, the patterns of the generated chaotic signals are completely changed and the chaotic oscillator is completely encrypted. At the receiving end, the newly developed Constrained Smoothed Regularized Least Square (CSRLS) observer is used to synchronize the received constrained chaotic signals and hence retrieve the transmitted data. Using such an approach, the quality of the received information, measured by the Bit Error Rate (BER), is highly improved due to the superior performance of the developed CSRLS observer. The stability of the observer is analyzed, and simulation results are presented to show the efficiency and effectiveness of the proposed secure communication scheme.     

Hybrid E‐Learning Acceptance Model: Learner Perceptions

E‐learning tools and technologies have been used to supplement conventional courses in higher education institutions creating a “hybrid” e‐learning module that aims to enhance the learning experiences of students. Few studies have addressed the acceptance of hybrid e‐learning by learners and the factors affecting the learners’ satisfaction with these tools. This study assesses hybrid e‐learning acceptance by learners using three critical success factors: instructor characteristics, information technology infrastructure, and organizational and technical support. Structural equation modeling was applied to examine and validate the hypothesized relationships among the three factors and their effects on learners’ acceptance of hybrid e‐learning. A total of 538 usable responses from university students were used to validate the proposed research model. The influence of the three factors on learners’ decision to accept hybrid e‐learning was empirically examined. The results show that all three factors significantly and directly impacted the learners’ acceptance of hybrid e‐learning courses. Information technology infrastructure and organizational support were proven to be key determinants of the instructor characteristics as a critical success factor of hybrid e‐learning acceptance by learners. Implications of this work for higher education institutions, researchers, and instructors are described.     

Preparation,Characterization and Cytotoxic Effects of Pegylated Nanoliposomal Containing Carboplatin on Ovarian Cancer Cell Lines

Carboplatin is a chemotherapeutic agent used against various malignancies such as ovarian carcinoma. The aim of this study is to improve the therapeutic efficacy of carboplatin using pegylated liposomal nanocarriers. Nanoparticles were synthesized using thin film hydration technique and characterized for shape morphology, particle size, zeta potential and drug-release properties. In the next step, A2780S and A2780CP ovarian cancer cell lines were used to determine the efficacy of nanodrug by MTT assay. The particle size and zeta potential of nanodrug were measured 244.3 ± 19.6 nm and ?22.9 ± 1.7 mV, respectively. High encapsulation capacity (78.6 ± 3.7 %) confirmed the efficiency of technique. The cytotoxicity results also showed that nanodrug compared to free drug improve the efficacy of carboplatin against both A2780S (P < 0.01) and A2780CP (P < 0.05) cell lines. In conclusion, the findings of our study suggested pegylated liposomal nanocarriers are proper for carboplatin delivery to ovarian cancer cell lines A2780S and A2780CP.     

Individual and collaborative technology-mediated learning using question & answer online discussion forums – perceptions of Public Health learners in Dubai,UAE

This case study provides evidence-based suggestions for the use of Question and Answer discussion forums for improving quality and assessment of online learning. General online discussion forums are accessible at any time to all subscribers, making it possible for some learners to update, concur with or paraphrase discussions posted earlier by their peers or the tutors. Consequently, the usefulness of such forums in individual and constructivist learning is compromised, especially when ‘correct’ responses are posted early on by participants. The Question and Answer (Q & A) version of discussion forums significantly addresses such inadequacies by restricting access to forum subscribers until they have made a post. We focus on Public Health learners’ perceptions of Q & A discussion forums implemented at Hamdan Bin Mohammed Smart University, UAE. Analyses of learners’ perception surveys of 25 participating Master of Public Health learners and 8 Bachelor of Health Administration learners reveal that the Q & A discussion forum platform offers distinct advantages over general discussion forums in synergising individual and co-operative learning in Public Health training.
