Gender, citizenship and human reproduction in contemporary Italy

This article examines how the recently introduced law on assisted reproduction in Italy, which gives symbolic legal recognition to the embryo, came about, and how a referendum, which would have repealed large sections of it, failed. The occupation of the legal space by the embryo is the outcome of a crusade by a well-organised alliance of theo-conservatives. These groups see in reproductive medicine an uncontrolled interference with their notion of the natural order of things. Such a worldview requires a total ban on stem cell research, limitation of access to reproductive technologies and repressive laws to govern the area. This conservative dream scenario has come closer to being realised by the introduction of a law doing all of these things in the name of the protection of “Life”. In the case of this law, the “life” to be protected is the embryo. In the name of “Life”, scientific advances and individual liberty have been curbed. The politics of embryo citizenship is a politics which values the yet to come over the here and now, purgation over pleasure, and the transcendent over the material.     

Mapping Public Participation in Policy Choices

In an era of democratic discontent, more and better participation in policy making has become a standard expectation. Yet it is rarely clear what counts as participation, and how the many practices loosely bundled under the label should be understood. This paper has a modest undergrowth‐clearing objective: to examine assumptions behind competing typologies of participation, and to propose a classification framework less laden by idealist notions of democracy.     

Evaluation of Raman spectroscopy for the analysis of colored fibers: a collaborative study

A collaborative study on Raman spectroscopy was carried out by members of the ENFSI (European Network of Forensic Science Institutes) European Fibres Group (EFG) on three dyed fibers: two red acrylics and one red wool. Raman instruments from six different manufacturers were tested as well as nine different laser wavelengths ranging from blue (lambda = 458 nm) to near infrared-NIR (lambda = 1064 nm). This represents the largest comparison study of Raman analytical parameters carried out on identical fiber samples. For the chosen fiber and dye samples, red lasers (lambda = 633 and 685 nm) gave the poorest spectral quality whereas blue (458 nm), green (514 nm) and near infrared lasers (785, 830 and 1064 nm) provided average results. Blue (488 nm) and green lasers (532 nm) globally gave the best quality spectra. Fluorescence problems were often encountered with some of the excitation wavelengths and therefore a flexible Raman instrument equipped with different lasers can be recommended to measure forensic fiber samples. The instrument should also be equipped with a Raman microscope in order to be able to focus on a single fiber. This study shows that Raman spectroscopy usually enables the identification of the main dye present in a colored fiber; however, minor dye components are much more difficult to detect. SERRS (Surface Enhanced Resonance Raman Scattering) techniques give an improvement of the dye's spectral intensity but no spectral improvement was observed for the two red acrylic and red wool fibers tested.     

Survey of crowbar and household paints in burglary cases-population studies, transfer and interpretation

Experimental data useful for the interpretation of paint evidence recovered during burglary cases were obtained. A population study was carried out on 41 blue crowbars seized on suspects in Switzerland and 37 blue paints traces found at burglary scenes. Paint traces were also searched on the blades of 207 crowbars seized by the police in Switzerland and 24 white traces were analysed: these paints were analysed using infrared spectroscopy (FTIR) in order to estimate relative frequencies of each paint type. Simulated contacts were carried out between crowbars and painted wood in order to study the phenomenon of transfer and to evaluate the amount of paint transferred: a total of 198 simulations were carried out including individual, successive and cross transfer. The paint properties such as the chemical composition and its age influenced the amount of paint transferred. Cross transfer from the tool paint to the wood and vice versa was regularly observed. Moreover, secondary transfer of paint coming from the preceding wooden surfaces was also systematically observed: this could establish links between several burglary scenes and a suspected tool. A scenario of a burglary case involving the cross transfer between tool and household paints is proposed as a numerical example: the evaluation of such case was formalised using likelihood ratios based on the experimental data obtained.
