Ink Dating Using Thermal Desorption and Gas Chromatography/Mass Spectrometry: Comparison of Results Obtained in Two Laboratories

An ink dating method based on solvent analysis was recently developed using thermal desorption followed by gas chromatography/mass spectrometry (GC/MS) and is currently implemented in several forensic laboratories. The main aims of this work were to implement this method in a new laboratory to evaluate whether results were comparable at three levels: (i) validation criteria, (ii) aging curves, and (iii) results interpretation. While the results were indeed comparable in terms of validation, the method proved to be very sensitive to maintenances. Moreover, the aging curves were influenced by ink composition, as well as storage conditions (particularly when the samples were not stored in “normal” room conditions). Finally, as current interpretation models showed limitations, an alternative model based on slope calculation was proposed. However, in the future, a probabilistic approach may represent a better solution to deal with ink sample inhomogeneity.     

Badges of Modern Slavery

Notwithstanding the 19^th century formal abolition of slavery as legal ownership of people, modern slavery and forced labour have not been consigned to the past. In fact, their existence is more widespread, and made more difficult to tackle due to the lack of formal, legal criteria. This article suggests that reference to historical institutions reveals seven ‘badges of slavery’ that are helpful in identifying occurrences of modern slavery and forced labour. These are: humiliation, ownership of people, exploitation of the vulnerable, lack of consent, terms and conditions of employment, limits on the power to end the employment relationship, and denial of rights outside the work relationship. These constitute modern slavery, and distinguish it from other instances of exploitative employment relations, however problematic. In addition, even where the label of modern slavery is misplaced, the identification of particular badges of slavery in contemporary employment relations may assist in highlighting their troubling facets.     

A crisis of integration? The development of transnational dyadic trust in the European Union, 1954–2004

The healthy functioning and long‐term viability of the European Union (EU) ultimately depend on its citizens finding common cause and developing a shared sense of political community. However, in recent years, scholars and pundits alike have expressed doubts about whether the EU's growing cultural, religious and economic diversity is undermining the development of citizens' shared sense of political community, especially following eastern expansion. In this article, this question is examined using data on a key aspect of political community: transnational dyadic trust. Drawing on a unique set of opinion surveys from the formative years of the EU to the first wave of eastward expansion (1954–2004), the development and sources of dyadic trust among EU Member States is studied. While recognising the importance of diversity for trust judgments in the short‐term, the prevailing viewpoint that it is also a long‐term obstacle to integration is challenged. Instead, it is argued that citizens from diverse cultural and economic backgrounds can learn to trust one another and build a sense of political community over time through greater cooperation and interconnectedness. This theory is tested with data on bilateral trade density, which is seen as a proxy and precursor for other forms of cross‐national interconnectedness. Employing longitudinal models, the article also goes beyond existing research to test the theories over time. The study makes a contribution to the research on European integration, suggesting that over time mutual trust and a shared sense of political community can indeed develop in diverse settings.     

Academic freedom 1979: The West German case

Abstract

Given the continued significance of ideology as a social and political phenomenon, political science must consider the important contributions made to ideology theory made over the last thirty years by Louis Althusser. In this essay, I offer a critical exegesis of Althusser's views, focusing on the concept of reading, on the various conceptions of ideology held by Althusser, on the distinction Althusser made between ideology and science, and on his theory of the subject. This study of his thought makes three claims: (1) that Althusser's views, billed as a radical break with bourgeois thought, can be assimilated easily into social scientific understandings about ideology; (2) that Althusser's theory has internal difficulties rooted in the tension between positive and negative conceptions of ideology; and, (3) that Althusser left unanswered the key question of the means to ideological liberation.     

The Concealed Information Test is Susceptible to Misleading Information

An approach toward detecting hidden knowledge is the Concealed Information Test (CIT). It relies on the memory of crime‐relevant information. This study investigated whether its validity is susceptible to memory distortion by misleading information. A misleading information paradigm was employed to distort memory prior to an interrogation with a CIT. Forty‐one participants watched a video with specific crime‐related information. After a 1‐week retention interval, misleading information was introduced. Afterward, a CIT was performed, followed by a threefold memory test. When misleading information was presented, memory performance was reduced, and no physiological response differences between crime‐relevant and crime‐irrelevant information were found. Without presenting misleading information, physiological responses differed between responses to crime‐relevant and crime‐irrelevant information. However, responses in all physiological measures also differed between misleading and irrelevant information. The results indicate that the CIT is susceptible to misleading information, which reduces its validity in specific constellations.     

Postmortem evaluation of serum and urine neopterin concentrations

Cellular immune response is accompanied by the release of neopterin. Increased neopterin levels in urine and serum are observed in patients during viral infections, autoimmune diseases, and allograft rejections and certain malignant diseases. We investigated postmortem neopterin concentrations in urine and serum samples taken from 32 corpses 3 to 69 h (mean 19.3 h) after death. Urine neopterin concentrations in corpses are similar to those of healthy live controls and are independent of the time after death. In contrast, serum neopterin concentrations are frequently greatly increased in corpses, and the levels are higher in sera collected more than 10 h after death in comparison with samples obtained earlier. Neopterin measurement in urine and serum samples of corpses is feasible. It appears likely that urine neopterin concentrations could aid the diagnosis of inflammatory diseases in corpses.     

Vergabewettbewerb als Instrument. Zur Renaissance politischer Instrumentalisierung des Vergaberechts

Die Rede von "vergabefremden" Kriterien oder "Sekundärzwecken" der Vergabe stößt in der wissenschaftlichen Auseinandersetzung in aller Regel auf Skepsis und Mahnungen zur Vorsicht. Denn einer verstärkten Ausrichtung des Vergaberechts an "außerökonomischen" politischen Zielsetzungen wird das Potential zugemessen, die Funktionalität des Vergabewettbewerbs zu beeinträchtigen und damit dem vergaberechtlichen Ordnungsanliegen insgesamt zuwider zu laufen. Nichts desto trotz ist das Vergaberecht seit jeher und bis heute in einem signifikanten Ausmaß durch Ansätze einer politischen Instrumentalisierung geprägt. Bemerkenswerter Weise wird aktuell vor allem auf europäischer Ebene der Ruf nach einer ganzheitlichen, strategischen Beschaffungspolitik der Mitgliedstaaten, die bei der Auftragsvergabe auch politische Ziele und insoweit Interessen abseits der Sicherung der betriebswirtschaftlichen Effizienz der Beschaffung in den Blick nimmt, immer lauter. Der Beitrag will die Kernbedingungen der Nutzung des Vergabewettbewerbs als Instrument aufzeigen und Grenzen seiner Leistungsfähigkeit ausloten.
