The purpose of this paper is to use the kernel method to produce a smoothed receiver operating characteristic (ROC) curve and show how baby gender can influence Clinical Risk Index for Babies (CRIB) scale according to survival risks.

To obtain the ROC curve, conditioned by covariates, two methods may be followed: first, indirect adjustment, in which the covariate is first modeled within groups and then by generating a modified distribution curve; second, direct smoothing in which covariate effects is modeled within the ROC curve itself. To verify if new-born gender and weight affects the classification according to the CRIB scale, the authors use the direct method. The authors sampled 160 Portuguese babies.

The smoothing applied to the ROC curves indicates that the curve's original shape does not change when a bandwidth h=0.1 is used. Furthermore, gender seems to be a significant covariate in predicting baby deaths. A higher value was obtained for the area under curve (AUC) when conditional on female babies.

The challenge is to determine whether gender discriminates between dead and surviving babies.

The authors constructed empirical ROC curves for CRIB data and empirical ROC curves conditioned on gender. The authors calculate the corresponding AUC and tested the difference between them. The authors also constructed smooth ROC curves for two approaches.

This study aims to illustrate the potential of the many centuries-old universities buildings, in European cities, in a historical, architectural, aesthetic and symbolic dimension to diversify and differentiate urban tourist destinations supply.

This is a qualitative study supported by the analysis of public and classified documents, for which the main source is based on webography, and by conducting interviews.

The deficit of cultural tours, in the dimension of built heritage, is identified as one of the weaknesses of the city of Porto, as tourist destination, to be overcome. The interviewees are unanimous in recognizing the cultural, architectural and aesthetic impact of the historic buildings of the University of Porto, and most of them strongly agree with the integration of this legacy into the tourist offer of the city. The strategic sense of the heritage is emphasized, because of its location in charismatic areas of the city. The practice of effective networking, however, falls short of what is required to achieve ambitious and consistent objectives.

The practice of effective networking, however, falls short of what is required to achieve ambitious and consistent objectives.

Emphasis is placed on the cities’ built heritage as a type of heritage that defines their uniqueness. The dissemination of cultural itineraries, which allows tourists and the community itself a broader and deeper cultural knowledge, contributes to the effective understanding of historic cities’ tourism. Given the scarcity of studies on the relationship between historic university buildings and tourism, the relevance of research focuses on highlighting the contribution of these cultural elements, through a network-based dynamic, to urban tourism destinations’ attractiveness. In particular, the University of Porto's potential for the integration of structured tourism products that contribute to the diversification and differentiation of the city of Porto as a destination is illustrated.
