The current status of nanotechnology research and development in Jordan is analyzed. In recent years, Jordanian institutions demonstrated considerable interest in the development and production of nanotechnology. Here the purpose of this paper is to provide detailed information about the status of nanotechnology in Jordan in terms of several factors that influence selectivity in nanotechnology and the number of published peer-reviewed research articles.

Several factors that influence selectivity in nanotechnology and the number of published peer-reviewed research articles were analyzed. A detailed analysis of the collected data reveals that the number of publications, citations, and patents is highly dependent on the amount of research fund.

The development in nanotechnology is associated with presence and accessibility of sensitive laboratory equipment. The nanotechnology research output in Jordan is still lower than it should be due to the lack of necessary laboratory infrastructure. This is due to the insufficient funds allocated to scientific research, the restrictive access to available instruments and the bureaucracy of some governmental departments. Compared to some developed countries, Jordan is noticeably behind in developing a nanotechnology system of research and industry. It will take time as well as technical and financial resources in order to achieve an advanced level in the field of nanotechnology in Jordan. Nevertheless, many Jordanian researchers are doing their best and are producing some good research articles.

As an underlying entity in the discourses of privatisation of space, urban security and fear, boundary walls are considered as an impediment to the publicness of public spaces. But, the inevitability and potential of their physical attributes and functions is indicative of the lack of systemic knowledge on how to approach boundary walls, so that they contribute positively to the quality of urban spaces. The paper aims to discuss these issues.

Since boundary walls are constitutive of physical attributes that are embedded with multiple functions, the contribution of physical boundaries is premised on the interaction between objective and subjective measurements, explored in positive and ambiguous space types. In this study, the quality of physical boundaries is measured by an index and the perceived functions of the physical attributes of boundary walls are measured by a questionnaire survey.

This study found that positive and ambiguous space types not only affect the quality of physical boundaries but also the perceived functions of the physical attributes of boundary walls. Further, social and visual functions of boundary walls play a significant role in contributing positively to the quality of urban spaces.

By exploring the relation between quality of physical boundaries and their perceived functions, this study extends the meta-understanding of the role of boundary walls.
