African Olive (Olea europaea subsp. cuspidata) as an environmental weed in eastern Australia: a review

African Olive, Olea europaea subsp. cuspidata (Wall. ex G.Don) Cif. (family Oleaceae) is a dense-crowned tree introduced into Australia for horticulture in the mid 19th century. In recent decades, African Olive has become an aggressive woody weed, capable of forming a dense and permanent canopy in a wide range of vegetation types in south-west Sydney and beyond. Characteristics of African Olive invasion in south-west Sydney, and its seed dispersal by frugivorous birds are consistent with experience from Norfolk Island and Hawaii. We use records and aerial photographs from Mount Annan Botanic Garden and other bushland areas in south-west Sydney to describe the invasion stages and impacts of African Olive. The capacity for African Olive to establish in both temperate and subtropical zones, underlie the potential for spread well beyond current distribution in New South Wales. Research is now required to further develop control techniques and ecological restoration strategies for areas of heavy African Olive infestation. Mapping of current locations and a coordinated control strategy for African Olive is required to prevent future permanent loss of native plant diversity

The social, political and legal aspects of Text and Data Mining (TDM)

The ideas of textual or data mining (TDM) and subsequent analysis go back hundreds if not thousands of years. Originally carried out manually, textual and data analysis has long been a tool which has enabled new insights to be drawn from text corpora. However, for the potential benefits of TDM to be unlocked, a number of non-technological barriers need to be overcome. These include legal uncertainty resulting from complicated copyright, database rights and licensing, the fact that some publishers are not currently embracing the opportunities TDM offers the academic community, and a lack of awareness of TDM among many academics, alongside a skills gap

Why do we invest ethically?

Analysis in this paper has proposed three potential motives for ethical investment - financial returns, non-wealth returns and social change. The motives are developed from the literature and illustrated in the context of a 'best of sector' fund and a socially screened fund. We find that the proposed motives are neither exhaustive nor exclusive and one single motive will not explain the behaviour of all ethical investors. There may be a trade-off between financial and psychic returns for some investors. The trade-off for consumption-investors is expected to be close to zero (total utility is maximised with small levels of ethical investment in the fun of participation model) and is expected to vary with the ethical intensity of investment-investors, as shown when we include ethical intensity into the investor's utility function. Psychic return can also be viewed as an increase in happiness and this approach would lend itself to empirical testing to increase our understanding of why we invest ethically

Health Coverage and Access to Care for Hispanics in "New Growth Communities" and "Major Hispanic Centers"

Examines healthcare coverage for Hispanics when they migrate from cities to smaller urban and rural areas, and encounter roadblocks such as language barriers, lack of insurance, and access to health clinics

The added value from adopting a CGE approach to analyse changes in environmental trade balances

The application of multi-region environmental input-output (IO) analysis to the problem of accounting for emissions generation (and/or resource use) under different accounting principles has become increasingly common in the ecological and environmental economics literature in particular, with applications at the international and interregional subnational level. However, while environmental IO analysis is invaluable in accounting for pollution flows in the single time period that the accounts relate to, it is limited when the focus is on modelling the impacts of any marginal change in activity. This is because a conventional demand-driven IO model assumes an entirely passive supply-side in the economy (i.e. all supply is infinitely elastic) and is further restricted by the assumption of universal Leontief (fixed proportions) technology implied by the use of the A and multiplier matrices. Where analysis of marginal changes in activity is required, extension from an IO accounting framework to a more flexible interregional computable general equilibrium (CGE) approach, where behavioural relationships can be modelled in a more realistic and theory-consistent manner, is appropriate. Our argument is illustrated by comparing the results of introducing a positive demand stimulus in the UK economy using IO and CGE interregional models of Scotland and the rest of the UK. In the case of the latter, we demonstrate how more theory consistent modelling of both demand and supply side behaviour at the regional and national levels effect model results, including the impact on the interregional CO2 ‘trade balance’.modelling, MRIO, CO2 trade balance, environmental responsibility

Evaluation of the computers for pupils initiative: final report

The Computers for Pupils (CfP) initiative aimed to help overcome the digital divide, which can prevent young people from disadvantaged backgrounds from enjoying the benefits of access to information and communications technology. The initiative provided funding for schools in deprived areas to invest in home access to ICT for their neediest pupils in order to: • give eligible learners the same opportunities as their peers • contribute to raising educational achievement • support personalised learning • encourage the development of ICT skills among learners and families. In December 2006, Becta commissioned the National Foundation for Educational Research (NFER) to undertake a national evaluation of the CfP initiative. The main aim of the two-year evaluation was to assess the impact of CfP on learners and their families and to explore how schools and teachers had developed their pedagogic practices in order to support and capitalise on the new educational opportunities afforded by the technology. The evaluation involved distinct though interrelated strands of quantitative and qualitative research: • Questionnaire surveys of teachers in CfP schools, learners selected for CfP, and learners’ parents, which were conducted twice (autumn 2007 and 2008) in order to explore changes in general access to and use of computers and ICT, and assess the impact of the CfP initiative • In-depth case-study research across 13 schools within eight local authorities (LAs) in the spring and summer terms 2008 and again in the autumn term 2008 (including the same LAs and schools at all time points), in order to explore through detailed interviews perceptions of the implementation and impact of CfP. Key findings in relation to the aims of CfP

The national impact of regional policy : demand-side policy simulation with labour market constraints in a two-region computable general equilibrium model

UK governments generally advocate regional policy as a means of reducing regional disparities and stimulating national growth. However, there is limited comprehension regarding the effects of regional policy on non-target economies. This paper examines the system-wide effects on the Scottish and rest of UK (RUK) economies of an increase in Scottish traded sector exports to the rest of the world. The research is carried out in an inter-regional Computable General Equilibrium framework of the Scottish and RUK economies, under alternative hypotheses regarding wage determination and inter-regional migratory behaviour. The findings suggest that regional policy can have significant national spillover effects, even when the target region is small relative to the RUK. Furthermore, the configuration of the labour market is important in determining the post-shock adjustment path of both economies. In particular, while Scottish economy results are sensitive to alternative versions of how regional labour markets function, RUK region effects prove to be even more so
