Adequate, reliable, and efficient urban infrastructure systems (UIS) are fundamental to sustainable development, social mobility, and economic vitality. As communities continuously rely on basic infrastructure services to support their daily communal functions, major components of UIS are subject to heavy use, and thus rapidly deteriorate over time; hence, it is critical that efficient infrastructure management strategies practices are in place. As current strategies remain confronted with various limitations including adaptability to changing conditions, lack of public engagement, and cost-effectiveness, this study explores social media data mining as an approach to revitalise and support current urban infrastructure monitoring strategies by extracting valuable insights from public opinion. Twitter messages or ‘Tweets’ pertaining to public infrastructure in The Philippines were collected and analysed to identify recurring issues in public infrastructure, emerging topics in public discussions, and the overall perception of the public on infrastructure services. This study presents a topic model that extracts dominant topics from aggregated social media data and a sentiment analysis model that determines public opinion sentiment in relation to different urban infrastructure components. The findings of this study highlight the potential of social media data mining to surpass the limits of conventional data collection techniques and the importance of public opinion as a key driver for a more user-involved decision-making in infrastructure management and as an important social aspect that can be utilised to support planning and response strategies in routine maintenance, preservation, and improvement of UIS.

The macroenvironment constitutes a widely acknowledged source of firms’ risk in international business. A substantial body of research on macroenvironmental risks encapsulates a variety of measurement approaches, antecedents, and managerial consequences. However, a review of established macroenvironmental risk measures reveals that these measures strongly focus on the quality of the macroenvironment, assuming a rather static perspective and mainly excluding dynamic aspects. Building on prior research on macroenvironmental risk as well as on environmental dynamism, we argue that macroenvironmental dynamism – i.e. the frequency, intensity, and predictability of macroenvironmental variation – is a pivotal source of risk in international business, which so far only received limited attention. Moreover, we suggest that macroenvironmental dynamism influences firms’ risk management activities, a measure we use to empirically investigate firm implications of macroenvironmental dynamism. We explore this effect using primary survey data on risk management activities from 158 foreign subsidiaries in six emerging countries and secondary data on the macroeconomic context in these countries. We find evidence that macroenvironmental dynamism, if compared to macroenvironmental quality, exerts a strong influence on firms’ risk management activities. Our findings enhance the understanding of the dynamic nature of macroenvironmental risk in international business as well as provide a concept to more comprehensively measure macroenvironmental dynamism that future research can build upon.

Functionality as a measure of project performance encompasses definitions across literature, relevance and essentiality in construction as the industry moves towards sustainable construction. Functionality in this section shows details in social functionality, as well as functionalities expressed in assessing, implementing project performance within set out target and goal. Furthermore, for functionality to be truly experienced in construction, many factors have to be gotten right. One of such is decision making that tends towards standard expatiated in the contract agreed without compromising budget, performance, collaboration, health and safety, communication, profit, satisfaction, quality, project cost, profitability among others.

Value management is a conceptual process that ensures the use of alternative materials to increase the function, reduce time and eliminate unnecessary cost. This process spreads from when the client has given the brief to the used stage of the project. It involves gathering the professionals involved in the project by a value management facilitator for 40 hours of brainstorming and finding alternative materials to be used. Furthermore, the ways to avoid difficulty in the project are devised by looking critically into the brief and outline design, removing unnecessary costs found in the design or brief before the project comes to execution and achieving more functionality for the project while at the same time getting value for money. Australia experienced an improved economy with the implementation of value management into construction some years ago. This study is aimed at evaluating how value management is practiced in Australia and correspondent application of its tools on construction projects in Australia. This entails details relating to its application in the country's construction, history and methodology, the application of the practice, challenges faced, benefits and measures to enhance the industry. The study was rounded up with a conclusion to summarize the salient observations made during the study.
