The rationale for this study is that the social enterprise sector provides an important locale in which to situate research that aims to identify the impact of ICTs on development. Recognising the complex dynamics and range of actors involved in this diverse and emerging area of development practice, this study chooses to focus on the social enterprise sector. It is specifically concerned with mapping the external influences, use and impact of ICT on social enterprises in Cambodia.

Finance is considered as the lifeblood of the economy and it is integral to a country's economic growth and stability. However, this perception has been called into question, particularly following the global financial crisis, giving rise to new research questions. For example, does too much finance harm economic growth? And does the financial sector serve society's economic and social needs? This thesis aims to provide cross-sectional and time-series evidence on the macroeconomic consequences of financialisation in an international context.

This dissertation is composed of two parts, an integrative essay and a set of published papers. The essay and the collection of papers are placed in the context of development and application of time series econometric models in a temporal-axis from 1970s through 2005, with particular focus in the Marketing discipline. The main aim of the integrative essay is on modelling the effects of marketing actions on performance variables, such as sales and market share in competitive markets.

The central objective of the thesis "An economic analysis of the Australian Baby Bonus" is to examine the nature of the fertility response of Australian families to the financial incentive of the Baby Bonus. The efficacy of the policy in determining a change in both fertility and the timing of births is assessed by exploring the time series properties of national and Victorian fertility measures, while controlling for other possible determinants of fertility choice.

Understanding the tectonic mechanism generated by the earthquakes and faults is possible only if the preseismic, coseismic and postseismic crustal deformation related to the earthquakes is determined properly. By the analysis of continuous GPS (CGPS) coordinate time series, it is possible to estimate the crustal deformation. Besides, accelerometer records at strong motion stations (SMSs) may support the CGPS-based estimates.

The maximum lag effects were 3 weeks for temperature and humidity, 4 weeks for precipitation, and 6 weeks for SOI. Specifically, the relative risk of HFMD increased by 7.2 % for every 1°C increase .in temperature, 6.75 % for every 1 % increase in humidity, 6.32 % for every 5 mm increase in precipitation, 4.42 % for every 5 units increase in SOI. The study provided a quantitative evidence that the increase of HFMD was significantly affected by the increase of climate variations

This thesis examines empirically whether there is a link between education and economic growth in Chile during the period 1973-2005. This is done through the adoption of time-series analysis and co-integration techniques. Based on economic theory and empirical findings, potential implications for Chilean educational policy are then discussed.

Due to the unavoidable nonbiological variations accompanying many experiments, it is imperative to consider a way of unravelling the functional interaction structure of a cellular network (e.g. signalling cascades or gene networks) by using the qualitative information of time-series experimental data instead of computation through the measured absolute values.

In the chapter “Fourier Series, Fourier Transforms, and the DFT” by W. Kenneth Jenkins, many important Fourier transformconcepts in continuous and discrete time are presented. The discrete Fourier transform(DFT), which forms the backbone of modern digital signal processing as its most common signal analysis tool, is also described, together with an introduction to the fast Fourier transformalgorithms.
