TL;DR: In this paper, the authors used integrated assessment (IA) focus groups, in which groups of randomly selected individuals in Switzerland looked at models of possible consequences of climate change and questioned specialists as to their accuracy and meaning, revealed a rich assembly of reactions.
Abstract: Various studies of public opinion regarding the causes and consequences of climate change reveal both a deep reservoir of concern, yet also a muddle over causes, consequences and appropriate policy measures for mitigation. The technique adopted here, namely integrated assessment (IA) focus groups, in which groups of randomly selected individuals in Switzerland looked at models of possible consequences of climate change and questioned specialists as to their accuracy and meaning, revealed a rich assembly of reactions. Respondents were alarmed about the consequences of high-energy futures, and molli"ed by images of low-energy futures. Yet they also erected a series of psychological barriers to justify why they should not act either individually or through collective institutions to mitigate climate change. From the viewpoint of changing their lifestyles of material comfort and high-energy dependence, they regarded the consequences of possible behavioural shift arising from the need to meet mitigation measures as more daunting. To overcome the dissonance created in their minds they created a number of socio-psychological denial mechanisms. Such mechanisms heightened the costs of shifting away from comfortable lifestyles, set blame on the inaction of others, including governments, and emphasised doubts regarding the immediacy of personal action when the e!ects of climate change seemed uncertain and far away. These "ndings suggest that more attention needs to be given to the social and psychological motivations as to why individuals erect barriers to their personal commitment to climate change mitigation, even when professing anxiety over climate futures. Prolonged and progressive packages of information tailored to cultural models or organised belief patterns, coupled to greater community based policy incentives may help to widen the basis of personal and moral responsibility. 2001 Elsevier Science Ltd.

TL;DR: A novel theoretical framework is presented which highlights the associations between active travel behaviours and environmental factors, drawing upon both existing and hypothesised relationships, that integrates the environment into the wider decision making process around travel choices for children and adolescents.
Abstract: Many youth fail to meet the recommended guidelines for physical activity. Walking and cycling, forms of active travel, have the potential to contribute significantly towards overall physical activity levels. Recent research examining the associations between physical activity and the environment has shown that environmental factors play a role in determining behaviour in children and adolescents. However, links between the environment and active travel have received less attention. Twenty four studies were identified which examined the associations between the environment (perceived or objectively measured) and active travel among youth aged 5–18 years. Findings were categorised according to the location of the environmental measure examined; attributes of the neighbourhood, destination and the route between home and destination. Results from the reviewed studies indicated that youth active travel is positively associated with social interactions, facilities to assist active travel and urban form in the neighbourhood as well as shorter route length and road safety en-route. A conceptual framework is presented which highlights the associations between active travel behaviours and environmental factors, drawing upon both existing and hypothesised relationships. We provide a review of the available literature and present a novel theoretical framework that integrates the environment into the wider decision making process around travel choices for children and adolescents. Further work should explore associations where gaps in understanding have been identified, and account for the main moderators of behaviour so hypothesised associations can be confirmed.

TL;DR: In this paper, an objective scheme, initially developed by Jenkinson and Collison, is used to classify daily circulation types over the British Isles, along the lines of the subjective method devised by Lamb.
Abstract: An objective scheme, initially developed by Jenkinson and Collison, is used to classify daily circulation types over the British Isles, along the lines of the subjective method devised by Lamb. The scheme uses daily grid-point mean sea-level pressure data for the region. The results of the analysis over the period 1881-1989 are compared with ‘true’ Lamb weather types. The frequencies of objectively developed types are highly correlated with traditional Lamb types, especially so for synoptic (cyclonic and anticyclonic) types, although still good for wind directional types. Comparison of the two classification schemes reveals negligible differences between the correlations of the counts of circulation types and regional temperature and rainfall. The major difference between the two classification schemes is that the decline of the westerlies since 1940 is less evident with the objective scheme.

TL;DR: This work believes that their ensemble is the first ever classifier to significantly outperform DTW and raises the bar for future work in this area, and demonstrates that the ensemble is more accurate than approaches not based in the time domain.
Abstract: Several alternative distance measures for comparing time series have recently been proposed and evaluated on time series classification (TSC) problems. These include variants of dynamic time warping (DTW), such as weighted and derivative DTW, and edit distance-based measures, including longest common subsequence, edit distance with real penalty, time warp with edit, and move---split---merge. These measures have the common characteristic that they operate in the time domain and compensate for potential localised misalignment through some elastic adjustment. Our aim is to experimentally test two hypotheses related to these distance measures. Firstly, we test whether there is any significant difference in accuracy for TSC problems between nearest neighbour classifiers using these distance measures. Secondly, we test whether combining these elastic distance measures through simple ensemble schemes gives significantly better accuracy. We test these hypotheses by carrying out one of the largest experimental studies ever conducted into time series classification. Our first key finding is that there is no significant difference between the elastic distance measures in terms of classification accuracy on our data sets. Our second finding, and the major contribution of this work, is to define an ensemble classifier that significantly outperforms the individual classifiers. We also demonstrate that the ensemble is more accurate than approaches not based in the time domain. Nearly all TSC papers in the data mining literature cite DTW (with warping window set through cross validation) as the benchmark for comparison. We believe that our ensemble is the first ever classifier to significantly outperform DTW and as such raises the bar for future work in this area.

TL;DR: Overall, consistent with earlier predictions, there is no evidence of a major deviation from past trends in all-cause mortality rates, since the short-term mortality fl uctuations were mainly driven by suicides and road-traffi c fatalities.
