Urnfield Culture hilltop settlements are often associated with a predominant function in the settlement pattern. This study challenged the idea of centrality by means of density estimates and spatial ...inhomogeneous explanatory statistics. Reflecting on the differences in spatial trends and material culture, no conclusive evidence for a consolidation of power, economic, or cultic dominance was observed. The dataset strongly points towards the inapplicability of commonly used parametric and/or homogenous spatial algorithms in archaeology. Tracer variables as well as the methodological and theoretical limitations are critically reviewed and a methodological framework to increase the reproducibility and reusability of archaeological research is proposed.

Human T lymphotropic viruses (HTLVs) have a limited spread in the general populations of Western countries. Consequently, the transfusional risk for HTLV is consider to be low in Italy and the ...screening for anti-HTLV-I/II antibodies has not yet been introduced. In 1992, 1087 blood donors attending a transfusional center in northern Italy underwent anti-HTLV-I/II screening carried out by means of two different ELISA tests. Eleven individuals who were negative at the first test were borderline at the second, eight of them showing reactivity to Western blot (WB). Polymerase chain reaction (PCR) for the detection of HTLV DNA, subsequently performed on the peripheral blood mononuclear cells of these 11 subjects, was positive in the same 8 WB-reactive donors. Five of them were infected by HTLV-II, and three by HTLV-1. Our results confirm that the sensitivity of the ELISA tests actually used for the detection of HTLV-I/II antibodies is low, and that HTLV-infected blood donors may be frequently undetected. Moreover, in our study population, the prevalence of HTLV infection (0.73%) was greater than that which might be expected from the existing seroepidemiological data in Italy.
