Putting ourselves in another’s skin: using the plasticity of self-perception to enhance empathy and decrease prejudice

The self is one the most important concepts in social cognition and plays a crucial role in determining questions such as which social groups we view ourselves as belonging to and how we relate to others. In the past decade, the self has also become an important topic within cognitive neuroscience with an explosion in the number of studies seeking to understand how different aspects of the self are represented within the brain. In this paper, we first outline the recent research on the neurocognitive basis of the self and highlight a key distinction between two forms of self-representation. The first is the “bodily” self, which is thought to be the basis of subjective experience and is grounded in the processing of sensorimotor signals. The second is the “conceptual” self, which develops through our interactions of other and is formed of a rich network of associative and semantic information. We then investigate how both the bodily and conceptual self are related to social cognition with an emphasis on how self-representations are involved in the processing and creation of prejudice. We then highlight new research demonstrating that the bodily and conceptual self are both malleable and that this malleability can be harnessed in order to achieve a reduction in social prejudice. In particular, we will outline strong evidence that modulating people’s perceptions of the bodily self can lead to changes in attitudes at the conceptual level. We will highlight a series of studies demonstrating that social attitudes towards various social out-groups (e.g. racial groups) can lead to a reduction in prejudice towards that group. Finally, we seek to place these findings in a broader social context by considering how innovations in virtual reality technology can allow experiences of taking on another’s identity are likely to become both more commonplace and more convincing in the future and the various opportunities and risks associated with using such technology to reduce prejudice

Determining the optimum morphology in high-performance polymer-fullerene organic photovoltaic cells

This work was supported by the Engineering and Physical Sciences Research Council (grant number EP/I013288/1) and from the European Union Seventh Framework Programme under grant agreement 321305.The morphology of bulk heterojunction organic photovoltaic cells defines many of the device performance characteristics. Measuring the morphology is challenging due to the small length scales and low contrast between organic materials. Here we have utilised nanoscale photocurrent mapping, ultrafast fluorescence and exciton diffusion to observe the detailed morphology of a high performance blend. We show that optimised blends consist of elongated fullerene-rich and polymer-rich fibre-like domains which are 10-50 nm wide and 200-400 nm long. These elongated domains provide a concentration gradient for directional charge diffusion which helps extraction of charge pairs with 80% efficiency. In contrast, blends with agglomerated fullerene spheres show a much lower efficiency of charge extraction of ~45% which is attributed to poor electron and hole transport. Our results show that formation of narrow and elongated domains are desirable in bulk heterojunction solar cells.Publisher PDFPeer reviewe

Remote sensing, GIS and hydrological modelling for irrigation management

This paper gives an overview of literature and of work done by the authors between 1988 and 1993. It was presented at a NATO expert meeting on sustainability of irrigated agriculture in 1994. The paper deals with crop water requirements and crop waterstress, assessing irrigation performance with satellite data, monitoring drainage conditions and salt-affected areas, distributed hydrological models of irrigation schemes, water allocation on the basis of farmers' preferences, and management issues

The Dutch Fertility Paradox: How the Netherlands has managed to sustain near-replacement fertility

Fertility in the Netherlands has never dipped to the extremely low levels observed in some other European countries. The Netherlands has always maintained a total fertility rate (TFR, average number of children per woman) above 1.7. In 2009, the TFR was 1.88. The absence of direct family policies and the fact that the Netherlands is a highly secular society both make the country’s relatively high fertility, in a European context, appear as a paradox. The Dutch government provides substantial welfare benefits, but, given concerns about high population density, no specific policies have been implemented to raise fertility. Dutch society is characterized by a strong value preference for fathers to be the primary breadwinners and mothers to care for children at home. As a result, the Netherlands stands out as having the world’s highest fraction of women in the labor force who are part-time workers. Women tend to work in occupations that allow part-time work and higher work- family reconciliation, resulting in what has been termed unequal work for unequal pay. The state has had a paternalistic role—supporting mothers to work part time and providing child allowances and, until recently, free higherlevel education and generous benefits. The Netherlands shows that religion is not necessarily a prerequisite for fertility and that worklife reconciliation and individual control of fertility can sustain moderate fertility levels. The recent financial crisis, however, has called the sustainability of this system into question and has signaled the end of many generous state policies, combined with increased calls for women to become less reliant on their husbands and more economically independent

A systematic global stocktake of evidence on human adaptation to climate change

Assessing global progress on human adaptation to climate change is an urgent priority. Although the literature on adaptation to climate change is rapidly expanding, little is known about the actual extent of implementation. We systematically screened >48,000 articles using machine learning methods and a global network of 126 researchers. Our synthesis of the resulting 1,682 articles presents a systematic and comprehensive global stocktake of implemented human adaptation to climate change. Documented adaptations were largely fragmented, local and incremental, with limited evidence of transformational adaptation and negligible evidence of risk reduction outcomes. We identify eight priorities for global adaptation research: assess the effectiveness of adaptation responses, enhance the understanding of limits to adaptation, enable individuals and civil society to adapt, include missing places, scholars and scholarship, understand private sector responses, improve methods for synthesizing different forms of evidence, assess the adaptation at different temperature thresholds, and improve the inclusion of timescale and the dynamics of responses
