Energy Policy

This study explores the causal relationship between carbon dioxide (CO2) emissions, renewable and nuclear energy consumption and real GDP for the US for the period 1960-2007. Using a modified version of the Granger causality test, we found a unidirectional causality running from nuclear energy consumption to CO2 emissions without feedback but no causality running from renewable energy to CO2 emissions. The econometric evidence seems to suggest that nuclear energy consumption can help to mitigate CO2 emissions, but so far, renewable energy consumption has not reached a level where it can make a significant contribution to emissions reduction. © 2010 Elsevier Ltd.

Energy Economics

This article attempts to test the causal relationship between nuclear energy consumption and real GDP for nine developed countries for the period 1971-2005 by including capital and labour as additional variables. Using a modified version of the Granger causality test developed by Toda and Yamamoto (1995), we found a unidirectional causality running from nuclear energy consumption to economic growth in Japan, Netherlands and Switzerland; the opposite uni-directional causality running from economic growth to nuclear energy consumption in Canada and Sweden; and a bi-directional causality running between economic growth and nuclear energy consumption in France, Spain, the United Kingdom and the United States. In Spain, the United Kingdom and the USA, increases in nuclear energy consumption caused increases in economic growth implying that conservation measures taken that reduce nuclear energy consumption may negatively affect economic growth. In France, Japan, Netherlands and Switzerland increases in nuclear energy consumption caused decreases in economic growth, suggesting that energy conservation measure taken that reduce nuclear energy consumption may help to mitigate the adverse effects of nuclear energy consumption on economic growth. In Canada and Sweden energy conservation measures affecting nuclear energy consumption may not harm economic growth. © 2010 Elsevier B.V. Source

Nonlinear Analysis: Real World Applications

For competitive Lotka-Volterra systems, Ahmad and Lazer's work [S. Ahmad, A.C. Lazer, Average growth and total permanence in a competitive Lotka-Volterra system, Annali di Matematica 185 (2006) S47-S67] on total permanence of systems without delays has been extended to delayed systems [Z. Hou, On permanence of all subsystems of competitive Lotka-Volterra systems with delays, Nonlinear Analysis: Real World Applications 11 (2010) 4285-4301]. In this paper, existence and boundedness of nonnegative solutions and permanence are considered for general Lotka-Volterra systems with delays including competitive, cooperative, predator-prey and mixed type systems. First, a condition is established for the existence and boundedness of solutions on a half line. Second, a necessary condition on the limits of the average growth rates is provided for permanence of all subsystems. Then the result for competitive systems is also proved for the general systems by using the same techniques. Just as for competitive systems, the eminent finding is that permanence of the system and all of its subsystems is completely irrelevant to the size and distribution of the delays. © 2012 Elsevier Ltd.

Fuel poverty has been most commonly researched in the UK although it is experienced in other parts of Europe, to varying degrees. Boardman (1991) showed that energy inefficient buildings and heating systems are the most significant components of fuel poverty and highlighted the legacy of older buildings in this country that remain the majority of those now recognised as hard to treat. This paper considers the historical context for fuel poverty as a particularly British phenomenon. It examines claims that this is due to the mild climate and low indoor temperature expectations. It is concluded that there are significant differences from the European situation. The climate, particularly its characteristic changeability, has influenced building and heating methods, and the low priority given to energy efficiency by legislators. Significantly, economic priorities produced poor quality mass housing during the industrial revolution. The availability of coal encouraged the use of open fires, which demanded high ventilation rates. The British do value warmth but older buildings designed for heating with radiant open fires are difficult to adapt to convective central heating. Lessons can be drawn for newly industrialised economies similarly producing poor quality mass housing with low priorities for energy efficiency. © 2011 Elsevier Ltd. Source

To review available qualitative evidence in the literature for health beliefs and perceptions specific to UK South Asian adults. Exploring available insight into the social and cultural constructs underlying perceptions related to health behaviours and lifestyle-related disease. A search of central databases and ethnic minority research groups was augmented by hand-searching of reference lists. For included studies, quality was assessed using a predetermined checklist followed by metaethnography to synthesise the findings, using both reciprocal translation and line-of-argument synthesis to look at factors impacting uptake of health behaviours. A total of 10 papers varying in design and of good quality were included in the review. Cultural and social norms strongly influenced physical activity incidence and motivation as well as the ability to engage in healthy eating practices. These qualitative studies provide insight into approaches to health among UK South Asians in view of their social and cultural norms. Acknowledgement of their approach to lifestyle behaviours may assist acceptability of interventions and delivery of lifestyle advice by health professionals. Source
