Political Philosophy and Empowering Citizens

This paper defends the idea of empowering citizens by means of teaching them political philosophy. First, I explain and define empowerment as an experience leading to the development of critical and philosophical capabilities. Several challenges to using philosophy to empower citizens are then discussed and rejected. This group of challenges is called the 'divorce theory', because, according to them, philosophy and politics should be distinguished, as if divorced from each other, so that they can live happily side by side, but not together. Finally, empowerment is normatively defended and distinguished from paternalism, and examine the relationships between empowerment through political philosophy and deliberative 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.

Transnational and International Exploitation

There are four types of exploitation in the international arena: exploitation between states; exploitation within state A, the beneficiaries of which are mainly people in state B; exploitation of individuals from one country by another state in which they work; exploitation of individuals from one country by individuals in another state, in which they work. The Marxian and the liberal theories of exploitation are inadequate to discuss these cases. After exploring the difficulties of applying these theories to international and transnational exploitation, it is suggested that the theories could be reconstructed: exploitation is when the exploiter benefits from treating the exploitee not as equal in circumstances of bargaining. It is finally shown how this interpretation helps us in the discussion of all four types of international and transnational exploitation.     

Color separation of signature and stamp inks to facilitate handwriting examination

The questioned documents laboratory often encounters cases where handwriting that is to be examined intersects with some interfering factor such as a rubber stamp, typewriting or background printing. In these cases, line direction, beginning and ending features of letters and other fine details of the handwriting may be lost in the "noise" of the intersecting ink. The purpose of this paper is to show several new digital photography methods that may be used to "subtract" the effect of the intersecting ink, thereby enhancing that of the handwriting ink in order to enable the document examiner to conduct a complete examination. These methods have the advantage of being fast and do not involve the use of expensive material or equipment. Several new methods are described that may be used to separate the colors of the handwriting ink from that of the intersecting ink: the analog method and several digital methods such as RGB-HSB-CMYK, L*a*b color, and color separation using the Channel Mixer function of Adobe Photoshop. Successful application of these color separation methods to specific handwriting ink/rubber stamp ink color combinations shows that the effect of the intersecting ink may indeed be minimalized if not canceled altogether. Application of the suggested methods may well make the difference between a nonconclusive handwriting examination and a full analysis of the questioned handwriting.
