Songs to the Jinas and of the Gurus: historical comparisons between Jain and Sikh devotional music
Jain worship has always been accompanied by music and likewise for Sikhs the performance of and listening to the singing of hymns, as composed by several of their Gurus, continuously has been central to the community’s spiritual experience. For different reasons, however, Sikh and Jain devotional music, known as kirtan and bhakti respectively, until recently were neglected subjects in historiography. This article investigates the parallels and differences among the two genres from a historical comparative perspective against the successive backgrounds of the bhakti movement and Indic culture, the imperial encounter and globalization. In doing so, it particularly emphasizes the importance of identity politics to the making of modern Sikh and Jain devotional music, as well as the fact that, in comparison to Jain bhakti, Sikh kirtan generally remains North Indian ‘Hindustani’ art music, rather than regional folk music
The utility of NBS profiling for plant systematics: a first study in tuber-bearing Solanum species
Systematic relationships are important criteria for researchers and breeders to select materials. We evaluated a novel molecular technique, nucleotide binding site (NBS) profiling, for its potential in phylogeny reconstruction. NBS profiling produces multiple markers in resistance genes and their analogs (RGAs). Potato (Solanum tuberosum L.) is a crop with a large secondary genepool, which contains many important traits that can be exploited in breeding programs. In this study we used a set of over 100 genebank accessions, representing 49 tuber-bearing wild and cultivated Solanum species. NBS profiling was compared to amplified fragment length polymorphism (AFLP). Cladistic and phenetic analyses showed that the two techniques had similar resolving power and delivered trees with a similar topology. However, the different statistical tests used to demonstrate congruency of the trees were inconclusive. Visual inspection of the trees showed that, especially at the lower level, many accessions grouped together in the same way in both trees; at the higher level, when looking at the more basal nodes, only a few groups were well supported. Again this was similar for both techniques. The observation that higher level groups were poorly supported might be due to the nature of the material and the way the species evolved. The similarity of the NBS and AFLP results indicate that the role of disease resistance in speciation is limite

Changes in pupil dilation and P300 amplitude indicate the possible involvement of the locus coeruleus-norepinephrine (LC-NE) system in psychological flow
Psychological flow is a state of full task immersion. The present study was conducted to test the hypothesis that psychological flow is positively related to activity of the phasic locus coeruleus-norepinephrine (LC-NE) system, which supports decisions on whether to engage in or disengage from the current activity. Subjective flow was assessed among 36 participants who engaged in a gamified version of the n-back task with various difficulty levels (0, 1, 2, and 3 back). During the tasks, continuous pupil diameter and EEG were recorded. We found that psychological flow and two presumed indicators of the phasic LC-NE activity (pupil dilation and EEG P300 amplitude) fit inverted U-shapes with increasing subjective task difficulty. Moreover, a positive linear relationship between psychological flow and pupil dilation (not with P300) was found. In conclusion, this study indicates the involvement of the LC-NE system in the peak experience of flow.</p
