On the distance between cross-impact models: A set of metric measures for cross-impact analysis

This paper attempts to add to the Leibnizian or mathematical side of Technological Forecasting. Given two distinct cross impact models, the paper shows that there exists a set of appropriate metric measures such that the distance between any two cross impact models can be determined. That is, it is possible to say how close or how far apart two or more cross impact models are to one another. It is argued that the ability to make such determinations is vital to the formal and mathematical development and growth of Technological Forecasting.     

Population growth and the pattern of trade: A Neo-Ricardian approach

If the young and old provide economically distinct factors of production then the rate of growth of the population determines the factor endowment ratios and therefore both the composition of output and the pattern of foreign trade.     

Exploring online fitness culture and young females

Abstract

While previous studies have investigated online health communities and health-seeking behaviours, less attention has been directed at the growing impact of the online fitness movement. This paper draws on the concept of biopedagogies to examine the messages transmitted within fitness culture on social networking sites (SNSs), and their role as a channel for health and fitness information. To explore this, a multi-method approach was conducted. The two methods included a netnography (online ethnography) and 22 semi-structured individual interviews with female participants aged 18–24 in Australia. The study suggests that online fitness use is becoming a popular leisure activity and source of health and fitness information. It reveals how SNSs are used as a platform to gather and teach ideas of health and fitness, and the manner in which textual and photographic online communication facilitates the social construction and transmission of this knowledge. Results indicated that although fitness accounts on SNSs offer differing notions to present alternative and competing realities, users predominantly chose to follow the normalised and dominant health discourses. Noteworthy, the onus is firmly placed on the individual within these health and fitness messages to adhere to norms of correct health practices and choices. This has connotations relevant to eHealth literacy.
