Comparison of the h-index for different fields of research using bootstrap methodology

An important disadvantage of the h-index is that typically it cannot take into account the specific field of research of a researcher. Usually sample point estimates of the average and median h-index values for the various fields are reported that are highly variable and dependent of the specific samples and it would be useful to provide confidence intervals of prediction accuracy. In this paper we apply the non-parametric bootstrap technique for constructing confidence intervals for the h-index for different fields of research. In this way no specific assumptions about the distribution of the empirical h-index are required as well as no large samples since that the methodology is based on resampling from the initial sample. The results of the analysis showed important differences between the various fields. The performance of the bootstrap intervals for the mean and median h-index for most fields seems to be rather satisfactory as revealed by the performed simulation

Are You Talking to Me? The Nature of Community in Entrepreneurship Scholarship.

Research in entrepreneurship has grown rapidly, encompassing multiple theoretical and methodological traditions. This special issue is devoted to understanding the scientific structure of entrepreneurship research. Articles included in this issue use bibliometric techniques to find linkages within published entrepreneurship scholars. These analyses compellingly show that: research in our field contains: multiple but disconnected research themes; dominant research themes reflecting the disciplinary training and lens of authors; very few papers get cited even in our disciplinary journals; and key research themes and foci are subject to considerable dynamism and change. The articles provide rich opportunities for insightful, influential and creative research in the field
