- Description: Photophysical and two-photon-dependent nonlinear absorption properties of two chloroindium(III) phthalocyanines bearing pyrene units have been investigated. The tetra- (3) and the tri- (4) pyrene-substituted phthalocyanines exhibit strong triplet absorption with high triplet yields () of 0.79 and 0.83, respectively. The measured nonlinear optical data, such as the two photon absorption cross-sections, the third- and second-order nonlinearities were found to be comparable with those of literature, thus, making the compounds promising candidates for a broad range of nonlinear optical applications. , Original publication is available at http://dx.doi.org/10.1080/00958972.2014.959509

- Description: publisher version , The potential for national pride to take on shades of both the authentic and the hubristic is reflected in the International Social Survey Program's (ISSP) use of two different multi-item measures of national pride, a general and a domain-specific one. In contrast, domain-specific national pride is characterized as 'not overtly nationalistic, imperialistic, nor chauvinistic' and is expressed as positive feelings towards national accomplishments in a range of domains including arts, science and sport. Most scholars who take an interest in the impact of sport mega-events acknowledge that national pride is related to concepts such as patriotism and nationalism whose meanings are difficult to disentangle. The South African Social Attitudes Survey (SASAS), which has tracked the attitudes of South African adults around the 2010 World Cup, has confirmed this idea. The longitudinal SASAS study found that subsequent to the event, there was an enormous upswing in the belief that the World Cup had a positive impact on social cohesion.
