Adaptation to the impacts of climate change is a rapidly emerging, new area of knowledge and policy that is coevolving with political negotiations in the UN Framework Convention on Climate Change. As such, it offers the opportunity to study the coproduction of knowledge and social order within the climate change regime. A subset of adaptation knowledge relates to cost estimates of adaptation policy. Here the methodology of the adaptation cost studies are reviewed and compared to economic theory. Although presented as (...) technical and apolitical applications of economic theory, this analysis shows that these studies in fact differ significantly and consistently from theory in that they largely ignore autonomous adaptation and almost universally cost complete adaptation rather than an efficient level of adaptation. It is suggested that these differences are related to the political nature of adaptation cost estimates, which are closely connected with normative claims for both adaptation funding for developing countries and compensation for the unavoidable climate change impacts. As such, adaptation cost estimates are an example of boundary objects, used to manage normative and highly politicized claims for restitution using scientific and therefore apolitical language and framings.

There are growing concerns that increased screen device usage may have a detrimental impact on classroom behaviour and attentional focus. The consequences of screen use on child cognitive functioning have been relatively under-studied, and results remain largely inconsistent. Screen usage may displace the time usually spent asleep. The aim of this study was to examine associations between screen use, behavioural inattention and sustained attention control, and the potential modifying role of sleep. The relations between screen use, behavioural inattention, sustained attention (...) and sleep were investigated in 162 6- to 8-year-old children, using parent-reported daily screen use, the SWAN ADHD behaviour rating scale, The sustained attention to response task and the children’s sleep habits questionnaire. Tablet use was associated with better sustained attention performance but was not associated with classroom behavioural inattention. Shorter sleep duration was associated with poorer behavioural inattention and sustained attention. Sleep quality and duration did not act as mediators between screen usage and behavioural inattention nor sustained attention control. These findings suggest that careful management of the amount of time spent on electronic screen devices could have a beneficial cognitive impact on young children. The results also highlight the critical role of sleep in enhancing both behavioural attention and sustained attention, which are essential for supporting cognitive development and learning. (shrink)

Rather than renouncing empire after the fall of Napoleon, this essay argues, French liberal thinkers expressed a sustained preference for a strategy based on transnational connections, or what imperial historians describe as informal imperialism. The eulogy of European Christian civilization exemplified by François Guizot's lecture at the Sorbonne in 1828 served not only to legitimize French global ambitions, but also to facilitate cooperation with other European imperial powers, especially Britain, and indigenous collaborators. Liberal enthusiasm for the spread of Western civilization (...) also inspired the emergence of a French version of free-trade imperialism, of which the economist Michel Chevalier proved a consistent advocate. Only when such aspirations were frustrated did liberals reluctantly endorse colonial conquest, on an exceptional basis in Algeria after 1840 and on a global scale after 1870. The allegedly abrupt liberal conversion to empire in the nineteenth century may instead be construed as a tactical shift from informal to formal dominance. (shrink)

Most studies into the performance of socially responsible investment vehicles have focused on the performance of sustainable or socially responsible mutual funds. This research has been complemented recently by a number of studies that have examined the performance of sustainable investment indices. In both cases, the majority of studies have concluded that the returns of socially responsible investment vehicles have either underperformed, or failed to outperform, comparable market indices. Although the impact of sustainable indices to date has been limited, the (...) recent launch of sustainable indices by Dow Jones and FTSE suggests that more attention is being paid to the subject by financial markets, investors, and companies. This development raises a number of important issues which are reviewed in this article: (a) the performance of indices compared with their benchmark indices; (b) the methodologies employed in compiling the indices; and (c) the impact of the indices on companies and the investment community. The article concludes with a number of suggestions for areas that merit future research. (shrink)

The purpose of this article is to investigate how cultural meanings associated with the left ventricular assist device inform acceptance and experience of this innovative technology when it is used as a destination therapy. We conducted open-ended, semistructured interviews with family caregivers and patients who had undergone LVAD-DT procedures at six U.S. hospitals. A grounded theory approach was used for the analysis. Thirty-nine patients and 42 caregivers participated. Participants described a sense of obligation to undergo the procedure because of its (...) promise for salvation. However, once the device was implanted, patients described being placed into a liminal state of being neither sick nor healthy, with no culturally scripted role. Consideration of end-of-life decisions was complicated by the uncertainties about how patients with LVADs die. Pre-implantation communications among patient, family, and clinicians should take into account the impact of the technology on meaning, identity, and patient experience. (shrink)

Education is so strongly emphasized in the Chinese culture that academic success is widely regarded as the only indicator of success, while too much physical activity is often discouraged because it drains energy and affects academic concentration. This study investigated the relations among academic achievement, self?esteem, school conduct and physical activity level. The participants were 333 Chinese pre?adolescents (aged 8?12) in Hong Kong. Examination results and conduct grades were obtained from the school records. Global self?esteem was measured with the Physical (...) self?description questionnaire (PSDQ), while physical activity patterns of the children were assessed with the Physical activity questionnaire for children (PAQ?C). Results showed that high academic achievers consistently attained better school conduct marks. However, physical activity level was quite an independent entity that was related neither to academic achievement nor school conduct. Furthermore, regression analyses showed that only academically high?achieving boys and physically active boys had higher self?esteem. (shrink)

Dudo of Saint-Quentin, in his half-legendary account of the creation of Normandy c. 911, tells an engaging story about the Viking Rolf and the King of France. Rolf, after receiving the lands of the lower Seine from King Charles the Simple and doing him homage, was told that recipients of royal grants were expected to kiss the king's foot. Rolf replied that he would never bend his knee to anyone or kiss anyone's foot. But in response to further French entreaties (...) he allowed one of his warriors to do the honors. The warrior seized the king's leg, tipped him over backwards, raised the royal foot high in the air and kissed it, amidst the uproarious laughter of the Norse onlookers. (shrink)
