The application of these developments, both intellectually and materially, is being lost in a wave of western-inspired designs and structures, depriving its citizens of their rich cultural legacies, history and traditions. Amidst these modernizing developments, the residents of Dubai have very little to no engagement with these creations and are very selective with what they identify with within the larger context of their society. The overall aim of this doctoral study is to explore how Dubai’s urban identity is shaped within a socio-economic context. It illustrates the factors that have influenced Dubai’s urban development and also provides insight into the challenges faced by Dubai’s residents in connecting with their built environment. The case study approach employs a critical and multidisciplinary model based on archival research, literature review in four study areas – architecture and identity; Islam and the city; urbanism and placemaking; community development – and semi-structured interviews, that together contribute to the study of Dubai’s urban landscape. This approach is useful in analyzing Dubai’s phenomenal development as it offers an alternative to how mainstream literature on Dubai has always been addressed, mainly from a single lens of neoliberalism, form of governance and or the treatment of its migrant workers. The research study identifies three emergent themes – globalization, identity and change – in how Dubai’s urban identity is shaped. The research study concludes by acknowledging the complexity that is Dubai’s urban landscape and proposes further areas of study that would address how Dubai moves forward in its urban planning.

Wireless communication systems emit high-frequency waves both inside buildings and in the free space around us. There are a variety of EMW sources covering a wide range of the electromagnetic spectrum, spanning the frequency range from Hz to several hundred GHz. In building design, there are diverse approaches to provisions of wireless communication and constant innovation; however, the construction materials and EMW propagation relationship remain a secondary consideration. This research evaluates current power intensity levels range from 5 Hz to 10 GHz in building environments and develops guidelines for design professionals based upon an understanding of conventional building material properties. The research site survey that I conducted in the Calgary area, suggested in some cases, power spectral densities in building environments rose to levels that could possibly a problem. Incorporation of newly developed guidelines and security controls such as shielding, provided in this study, may prevent data confidentiality compromise in transit (e.g. eavesdropping) and prevent data integrity compromise in transit (e.g. hacking) for wireless communication systems in building environments. In this research, I develop the concept that effective EMW shielding can be achieved using conventional construction materials. The results of this study have significant implications for architectural design. The design method would reduce high power spectral densities by improving EMW shielding. Ultimately, I would like to see the developed shielding method in building codes and used in building projects all over the world.
- ItemOpen AccessInformal Settlement in Lagos State: A Framework for Investigating Housing Quality(2018-12-21) Fasakin, Temitope Oluwole; Graham, Livesey; Fadamiro, Joseph A.; Getachew, Assefa; Keenan, Thomas P.Ajegunle is one of the most popular areas in Lagos, Nigeria. Known for its high concentration of poverty and sprawling informal settlements, this area served as the site of analysis for this study. More specifically, the housing conditions within an informal settlement area of Ajegunle was analyzed in order to assess the quality and durability of the housing structures, the quality of the living conditions in the immediate environment of the neighborhood, and the overall quality of life of the inhabitants in the Ajegunle area. The aforementioned areas were assessed using the guidelines of the UN Habitat (2015), which presents conditions to determine areas of informal settlement. The factors include absence or limited: access to improved water; access to improved sanitation facilities; sufficient living space; adequate structural quality or durability; and security of living tenure. Based on the findings of this study, Ajegunle is an informal settlement area, since it meets the aforementioned criteria listed by UN Habitat (2015). In order to mitigate these conditions, the federal and local governments, with the assistance of non-governmental organizations (NGOs) will need to enact enduring measures that can improve the quality of living of residents in these areas.

- ItemOpen AccessStrategic studies and cyberspace: Iranian political unrest on Twitter(2011) Saint-Louis, Herve; Keenan, Thomas P.How could a Website about nothing, where people post short messages no longer than 140 characters could have become the conduit through which information about ongoing political unrest in a land foreign to most westerners become so important? Iranians were comparatively late as Cyberspace participants. Blogging only started in late 2001. But within a few months, the Iranian output in Cyberspace became voluminous. Iranians of all ages and creeds had found one place where they could express their political, views, discuss their country's rich and extensive literature, study religious texts and communicate with one another often bypassing the Iranian authorities' control of other media. This vibrant online activity was generated by Iranians for Iranians. Even through social networks, Iranians continued to speak to one another and generally not with outsiders. When Twitter became the last conduit, inconveniently forgotten by Iranian authorities in anticipation of the 2009 Iranian presidential election, many Iranians went to Twitter to express their dissatisfaction with the electoral results that made incumbent President Mahmoud Ahmadinejad the winner. This study argues that the very act of going online and disagreeing with the electoral results by Iranian dissidents was a war of ideas. Wars of ideas are cyber threats that can be studied within cyber security. Cyber threats are based on information systems and information content. Information content is about cyber influence and wars of ideas that can change people's opinions. But before one can understand what cyber threats, influence and attacks are, one needs to understand what cyber security is and how it exists within the field of strategic studies.
