In-event background and signal reconstruction for two-photon invariant-mass analyses

A method is presented for the reconstruction of both the background and signal in invariant-mass analyses for two-photon decays. The procedure does not make use of event mixing techniques and as such is based exclusively on an event-by-event analysis. Consequently, topological correlations of the event (e.g. jet structures) are automatically taken into account. By means of the decay process $\pi^{0} \to \gamma \gamma$ it will be demonstrated how the procedure allows for determination of the $\pi^{0}$ yield from the observed decay photons

Wage effects of motherhood: a double selection approach

Wage differentials between mothers and childless women are estimated correcting for the selectivity bias resulting from two double selection processes: firstly, the motherhood decision and the employment decision, and secondly the motherhood decision and the decision to be employed in a less demanding job. We use Dutch data on women’s wages and construct an indicator for less demanding jobs. Our estimations indicate that the motherhood decision is strongly correlated with both employment and having a less demanding job. This suggests that ignoring these correlations will lead to inconsistent parameter estimations of wage equations. The selectivity corrected estimation of women’s wage differentials indicate that a large part of the wage differential is composed by discrimination compared to estimations without correction for selectivity.

The Role of Corporate Image and Extension Similarity in Service Brand Extensions

In this article we examine the role of corporate image in extending service brands to new and traditional markets in the telecommunications sector. With regards to corporate image, service brand extensions are primarily associated with innovation-related attributes, such as order of entry (i.e., pioneers versus followers). Increasingly, firms are extending their services to markets that are beyond the markets that they traditionally have been active in. The results of an experimental study show that consumers evaluate service extensions by providers with an innovative late mover image more favourably that service extensions by companies with a pioneer image in terms of perceived corporate credibility and expected service quality. With regards to these evaluation criteria, it was also found that consumers prefer service brand extensions to related rather than unrelated markets. In addition we find that the relative distance between service providers with an innovative late mover image and pioneers is larger in related markets.marketing ;
