Construction projects often do not meet their targets, and usually face time and cost overruns (Agyakwah-Baah & Fugar, 2010; Memon, Abdul, & Abdul, 2012). Due to the complexity and dynamic nature of these projects, it is difficult for project managers to meet project objectives (Collyer & Warren, 2009). A substantial amount of work has been done to overcome this problem by developing different tools and methods, yet often projects still cannot meet their targets (Acebes, Pajares, Galán, & López-Paredes, 2014; Y. Chen, Zhang, Liu, & Mo, 2012). In the construction industry, a rich body of research has emerged to develop frameworks and tools for project management. The majority of current tools do not consider the dynamic nature of projects (Franceschini, Maurizio, & Domenico, 2007). Therefore, in this research, a decision support framework has been developed for the planning phase of a project lifecycle. In addition, a navigational support system has been created for the execution phase of the project lifecycle to monitor and control project performance. This thesis focuses on creating two artefacts: [1] a decision support framework for planning construction projects under uncertainty, in particular, severe weather conditions, and [2] a decision support system as a generic engine for controlling and monitoring key performance indicators at project level. For validation, we applied both artefacts to the construction industry and selected construction projects as cases. It is important to estimate a project’s duration properly in the initial phase to avoid cost and time overruns. Thus, the developed decision support framework in this thesis fills the gap in the phase of project planning by estimating project duration and taking into account the effect of weather on project performance and construction activities. Initial project planning is essential, but it is important to monitor and control the project to bring the project back on track if it veers off from the desired performance. Hence, project managers are keen to know the position of project performance with respect to the agreed criteria and what action to take to bring the project back on track. Thus, a decision support system called Navigational Support System (NSS) has been created to monitor and control project performance among multiple key performance indicators. This research consists of three original papers. Paper I provides a comprehensive review of the literature on the possible causes of delays, the problems with current methods and tools in construction projects in estimating project duration. This paper fills a gap in the literature by proposing a decision support framework to estimate project performance and duration with respect to weather, and presents a model developed through the proposed framework and validated in a real-case construction project. Paper II provides a comprehensive review of literature on the problems of existing performance measurement tools. A conceptual framework of the Navigational Support System (NSS) (Marzoughi & Arthanari, 2016a) based on the idea of navigating in benchmark space, introduced by Arthanari (2010), and the architecture of NSS is proposed. In addition, this paper illustrates the NSS using a case from interior design projects. Finally, Paper III illustrates the implementation of the generic engine proposed in Paper II for further validation in a real-life construction project. In this research, different methodologies have been used to validate both the decision support framework and NSS. In Paper I, multiple methodologies are used to integrate five modules (expert knowledge module, filtration module, multicriteria decision-making module, forecasting module and estimation module) to estimate the duration of construction project activities. Moreover, the techniques applied to integrate weather related variables in the process of estimating the duration of activities affected by weather, such as multivariate data analysis methods including principal component analysis, time series model building approaches, multi-criteria decision-making tools, non-linear multiple regression, and qualitative and quantitative data collection methods are introduced. In Paper II, a Navigational Support System (NSS) is created as a generic engine using design science research methodology. Multivariate statistical techniques and dynamic decision-making techniques were integrated to create the NSS. In Paper III, the NSS has been implemented in construction projects for validating created artefacts. Finally, the efficacy, validity and ease of use of the NSS are evaluated through applying the NSS in a real-life construction project.

This book examines issues and implications of digital and social media marketing for emerging markets. These markets necessitate substantial adaptations of developed theories and approaches employed in the Western world. The book investigates problems specific to emerging markets, while identifying new theoretical constructs and practical applications of digital marketing. It addresses topics such as electronic word of mouth (eWOM), demographic differences in digital marketing, mobile marketing, search engine advertising, among others. A radical increase in both temporal and geographical reach is empowering consumers to exert influence on brands, products, and services. Information and Communication Technologies (ICTs) and digital media are having a significant impact on the way people communicate and fulfil their socio-economic, emotional and material needs. These technologies are also being harnessed by businesses for various purposes including distribution and selling of goods, retailing of consumer services, customer relationship management, and influencing consumer behaviour by employing digital marketing practices. This book considers this, as it examines the practice and research related to digital and social media marketing.

"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

"While the energy sector is a primary target of efforts to arrest and reverse the growth of greenhouse gas emissions and lower the carbon footprint of development, it is also expected to be increasingly affected by unavoidable climate consequences from the damage already induced in the biosphere. Energy services and resources, as well as seasonal demand, will be increasingly affected by changing trends, increasing variability, greater extremes and large inter-annual variations in climate parameters in some regions. All evidence suggests that adaptation is not an optional add-on but an essential reckoning on par with other business risks. Existing energy infrastructure, new infrastructure and future planning need to consider emerging climate conditions and impacts on design, construction, operation, and maintenance. Integrated risk-based planning processes will be critical to address the climate change impacts and harmonize actions within and across sectors. Also, awareness, knowledge, and capacity impede mainstreaming of climate adaptation into the energy sector. However, the formal knowledge base is still nascent?information needs are complex and to a certain extent regionally and sector specific. This report provides an up-to-date compendium of what is known about weather variability and projected climate trends and their impacts on energy service provision and demand. It discusses emerging practices and tools for managing these impacts and integrating climate considerations into planning processes and operational practices in an environment of uncertainty. It focuses on energy sector adaptation, rather than mitigation which is not discussed in this report. This report draws largely on available scientific and peer-reviewed literature in the public domain and takes the perspective of the developing world to the extent possible."
