The currently consumption-driven society produces an enormous volume of waste every day. Continuous depletion of natural finite resources by urban populations is leading the globe to an uncertain future. Therefore, to prevent further depletion of global resources, sustainable consumption and a strategic waste management system would be required. It is evident that a significant number of global...

City Indicators are metrics used to measure city performance. Global City Indicators, as developed by the Global Cities Institute at the University of Toronto, are metrics that have been agreed to by over 250 cities world wide and have been approved as ISO 37120. The definitions of the indicators exist only in written form. The purpose of this research is to provide an ontology for representing...

Mathematical models that describe the global spread of infectious diseases such as influenza, severe acute respiratory syndrome (SARS), and tuberculosis (TB) often consider a sample of international airports as a network supporting disease spread. However, there is no consensus on how many cities should be selected or on how to select those cities. Using airport flight data that commercial airl...

Development and environmental issues of small cities in developing countries have largely been overlooked although these settlements are of global demographic importance and often face a “triple challenge”; that is, they have limited financial and human resources to address growing environmental problems that are related to both development (e.g., pollution) and under-development (e.g., inadequ...

Shrinking cities are widespread throughout the world despite the rapidly increasing global urban population. These cities are attempting to transition to sustainable trajectories to improve the health and well-being of urban residents, to build their capacity to adapt to changing conditions and to cope with major events. The dynamics of shrinking cities are different than the dynamics of growin...

While spatial boundaries include the geographic differences among team members (e.g., different cities), temporal boundaries include the workday differences among team members (e.g., different time zones). In global teams, members have to deal with both spatial and temporal boundaries, since their co-workers are often located in cities within and across time zones. For global team members with ...

While spatial boundaries include the geographic differences among team members (different cities), temporal boundaries include the workday differences among team members (different time zones). In global teams members have to deal with both spatial and temporal boundaries since their co-workers are often located in cities within and across time zones. For global team members with high spatial b...
