© 2014. The Authors.The global characteristics of tropical cyclones simulated by several climate models are analyzed and compared with observations. The global climate models were forced by the same sea surface temperature fields in two types of experiments, using climatological SST and interannually varying SST. TC tracks and intensities are derived from each model's output fields by the group who ran that model, using their own preferred tracking scheme; the study considers the combination of model and tracking scheme as a single modeling system, and compares the properties derived from the different systems. Overall, the observed geographic distribution of global TC frequency was reasonably well reproduced. As expected, with the exception of one model, intensities of the simulated TC were lower than in observations, to a degree that varies considerably across models. Key Points: Multimodel comparison of tropical cyclone activity in global climate models Geographic distribution of the TC activity is similar to observed Most models produce tropical cyclones weaker than observed.

Fragile X premutation carriers are characterized by 55-200 CGG trinucleotide repeats in the 5' untranslated region on the Xq27.3 site of the X chromosome. Clinically, they are associated with the fragile X-Associated Tremor/Ataxia Syndrome, a late-onset neurodegenerative disorder with diffuse white matter neuropathology. Here, we conducted first-ever graph theoretical network analyses in fXPCs using 30-direction diffusion-weighted magnetic resonance images acquired from 42 healthy controls aged 18-44 years and 46 fXPCs. Globally, we found no differences between the fXPCs and HCs within each gender for all global graph theoretical measures. In male fXPCs, global efficiency was significantly negatively associated with the number of CGG repeats. For nodal measures, significant group differences were found between male fXPCs and male HCs in the right fusiform and the right ventral diencephalon, and in the left hippocampus [for nodal clustering coefficient ]. In female fXPCs, CC in the left superior parietal cortex correlated with counting performance in an enumeration task. © 2014 Wiley Periodicals, Inc.

This article attempts to investigate the three strands of citizenship, nationalism and education and their interconnectedness in India after independence. It seeks to address questions like how has the post-colonial state in India visualized its models of citizenship through its education policies and programmes and what has become of their fate? In what ways the changing nature of public versus private education has shaped contested models of citizenship? What challenges are thrown at the models of citizenship that the Indian state has tried to posit through education? It is argued that the journey of citizenship in post-independent India is that of contradictory pulls around key strands of ethno-cultural nationalism and civic nationalism and around an economically productive nation versus an economic consumer nation. The article will look at some of the key policy shifts and operational models and attempt to locate the dynamic behind those shifts.

Agrarian environments have to be comprehended as being part of a biophysical and social environment that includes the urban and the nonurban, the arable and the nonarable, and other areas that are integrally linked to the world of agriculture and environment and their allied socioeconomic relations. This article examines the responses of rice biotechnologists located in selected Indian public agricultural institutes under the aegis of the State Agricultural University and the Indian Council of Agricultural Research on questions such as “How is GM (genetically modified) technology perceived by rice biotechnologists and under what limiting conditions is it being pursued in rice biotechnology research? Is there a consensus among rice biotechnologists over the application of GM technology? What are the complexities of the GM policy? and What are the implications of intellectual property rights on GM-based research and how scientists are responding to such institutional norms?”
