A stem-family society without the stem-family ideology? The case of eighteenth-century Poland1

This paper mobilizes historical census microdata and quantitative methods to answer a seemingly qualitative question of whether the stem-family organization, profoundly described in sociological and anthropological literature, existed in historical western Poland. The paper’s narrative takes a threefold argumentation format, each step relying on different methodologies. First, using household registers data and basic tools of historical demography we come to the point where a conjectural hypothesis of stem-family prevalence in the territories in question seems to be necessarily rejected. However, the vivid prevalence of the stem family is brought back to the fore in the second step, when empirical data are combined with more sophisticated statistical tools (computer microsimulation of kin sets). Finally, the latter observation is problematized in light of the historical contextual information, which altogether makes the incidence of stem-family organization in the region unthinkable given the existing socio-cultural and political-economic framework. We close with a contemplation of the limits of quantitative approaches to concerns over historical family systems, and with a discussion of the extent to which – given this apparent conundrum – our findings may illuminate existing models of historical family systems.     

Application of capillary electrophoresis to examination of color inkjet printing inks for forensic purposes

In the process of questioned document examination, the discrimination of inkjet printing inks is becoming more necessary due to increasingly frequent counterfeiting of documents printed by inkjet printers. Therefore, a method based on micellar electrophoretic capillary chromatography (MECC) has been developed and applied to analysis of such inks extracted from paper. With the use of an optimized and validated analytical procedure, multielectropherograms of inks taken from various models of printers made by various producers (Hewlett-Packard, Epson, Brother, Lexmark and Canon) were created. It was shown that effective differentiation of individual inks was possible in terms of migration time, order and specific shapes of characteristic peaks. By comparison of recorded UV-Vis spectra, the identification of main dyes was also achievable. The usefulness of the method was confirmed by an intralaboratory test of utility, in which several forged printouts were successfully examined. The obtained results proved that the proposed procedure is a useful tool that could be applied to ink discrimination and group identification of dyes originating from inkjet printing inks. Consequently, the developed method can be applied in the forensic field, including investigation of the authenticity of documents.     

Historical family systems and contemporary developmental outcomes: what is to be gained from the historical census microdata revolution?

Recent years have witnessed a growing interest in the role of the historical family as the instigator of disparate developmental trajectories. However, a major challenge faced by these studies was that they had to work around a lack of reliable historical data. This study demonstrates how embarking on the recent outburst of historical microdata infrastructures may help to improve these explorations by suggesting additional statistics and a derived measure (the Patriarchy Index) that might prove useful in future efforts aimed at assessing the effect of historical family organization on comparative development. The added value of that endeavour is assessed by comparing the predictive validity of the PI for contemporary developmental gradients against a composite indicator of family organization previously used by economic historians (Carmichael’s ‘Female Friendliness Index’). The results indicate that conclusions about the relationship between historical family organization and various societal outcomes may be sensitive to the measure used. Based on the evidence presented in this paper, it is argued that one of the reasons why the potential importance of historical family for contemporary developmental disparities has not been convincingly unravelled could be inadequacy of data and indicators so far employed to assess historical family formations. To the extent that the Patriarchy Index would be taken up by wider scholarly circles as an indicator of historical family organization it could help unravel potentially new associations between past and present, at least as far as Europe is concerned.
