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.  相似文献

A Qualitative Student Evaluation of Group Learning in Higher Education     

Ahmed Hassanien 《Higher Education in Europe》2007,32(2-3):135-150

The importance of group learning has increased significantly in higher education in the past two decades (Houldsworth and Mathews, 2000 Houldsworth, C. and Mathews, B. P. 2000. “Teaching Group Process Skills to MBA Students: A Short Workshop”. Education + Training, 42(1): 40–53.  [Google Scholar]). The primary focus of this study is to explore the feelings and experience of students regarding group work and group assessment in higher education. The study is exploratory based on a qualitative focus group approach. Interestingly, students felt that group work is a significant method to foster the development of critical thinking through discussion, clarification of ideas, and evaluation of others' ideas. Students consider “poor communication” and “poor attendance at group meetings” as the main challenges they face when working within a group. Also, students identified “dedicated assignment seminars” as the most effective tool, which could be used to enhance the effectiveness of group work. This study reinforces the findings of previous research into group work suggesting that the experience is a generally positive one for students. Results are discussed in the context of current theoretical and empirical work on group‐based learning, education implications and areas for further research are discussed.  相似文献   

Risen Apes and Fallen Angels: The New Museology of Human Origins     

Stephen T. Asma 《Curator: The Museum Journal》2011,54(2):141-163

Abstract There has been a little explosion of “origin” exhibitions in the past few years. The recent bicentennial of Darwin’s birth, in 2009, ushered in a bevy of traveling exhibitions and events. Grand‐scale permanent exhibitions have recently opened at the American Museum of Natural History (the Spitzer Hall of Human Origins) in New York, and the Smithsonian’s National Museum of Natural History (the David H. Koch Hall of Human Origins) in Washington, D.C. A new museology is afoot, and some of the recent changes are worth tracking. And let’s not forget the recently opened Creation Museum in Petersburg, Kentucky. Even in creationist thinking, where views seem eternally and stubbornly intransigent, there are new fads and museological fashions.  相似文献   

Economic dimensions of sustainable development, the fight against poverty and educational responses     

Manzoor Ahmed 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2010,27(1):235-253

The arguments in the article are based on the ongoing discourse in the academic community and among stakeholders, which has contributed to the articulation of the concepts and premises of sustainable development and the role of learning modalities, technologies and networks. The article draws on this discourse to explore the economic aspects of sustainable development, focusing on pervasive poverty, and the implications for educational actions. The concepts and underlying premises of education for sustainable development (ESD) are discussed. The article presents the key elements of an integrated approach to fighting poverty in the context of sustainable development. The role of learning and education in this integrated approach is outlined, framing the educational elements within the perspective of lifelong learning.  相似文献   

Multiple providers and access to primary education: The case of Bangladesh     

Zia-Us-Sabur  Manzoor Ahmed 《Prospects》2010,40(3):393-415

Even though most children in Bangladesh are enrolled in school, the country faces enormous challenges in ensuring that children complete primary education, and learn an acceptable amount. Multiple providers—state, quasi-state, and non-state—have helped to raise the initial enrolment rate and improve the gender balance. The critical question is how the multiplicity and diversity of provision can contribute to achieving truly universal primary education with high completion rates and acceptable levels of learning. A range of sub-questions relate to this critical question, including what is meant by multiple provision and how a diversity of provisions can be shaped into a system that serves the goal of effective and equitable access. This article addresses the above questions in the context of the history and educational development in Bangladesh. They are particularly significant at present, as the government is about to implement a new national education policy and design a five-year national development plan (2011–2015), which would have a decisive impact on progress towards achieving the EFA goal of universal primary education by 2015.  相似文献

Pastoral Care to Regulate School Bullying: Shame Management among Bystanders     

Eliza Ahmed 《Pastoral Care in Education》2005,23(2):23-29

Bystanders can reveal valuable information about bullying to school personnel to take action on it. If they remain reluctant, of course, they frustrate our efforts to stop bullying. But then, why would they get involved if doing so might make them victims of aggression too?
This paper investigates the importance of adaptive shame management in encouraging bystanders to prevent bullying. Data were collected through the Cross-national School Behaviour Research Project from 1452 secondary school students (49% girls) in grades 7–10 (mean=8.42) in Bangladesh. As predicted, students who scored higher on shame acknowledgement (admitting shame, accepting responsibility, making amends) were more likely to intervene to prevent bullying. Those with low shame displacement (blaming or hitting out at others) were also likely to intervene to stop bullying. Implications of these findings pertaining to pastoral staff, counsellors and school teachers working with students to encourage coming forward against bullying are discussed.  相似文献

A study of cross-national collaborative research: reflecting on experience in Pakistan     

Alan J. Penny  Mehru Ahmed Ali  Iffat Farah  Sissel Ostberg  Robert L. Smith 《International Journal of Educational Development》2000,20(6):443-455

This paper seeks to offer insights into the complexities involved in cross-national collaborative research. It identifies and provides an account of the various issues running through the research process, whilst at the same time derives principles upon which such work should be based. Key narratives were identified by highlighting a number of critical incidents. These narratives were related to issues of ownership, trust, and power, whilst in the course of theorising the research process itself, the metaphors of voice and crossing borders were found to be profoundly empowering and transformative. The complexities of working cross-nationally in the research group, understanding roles, clarifying professional frames and ethical values, at the same time as creating and maintaining a context for effective partnership and participation, made managing and sustaining the research process challenging.  相似文献
