Policy networks and the GM crops issue: assessing the utility of a dialectical model of policy networks

A dialectical model of policy networks is deployed to analyse policy change in the area of GM crops in the UK. The model uses an analysis of the interaction between agents and structure, network and context and network and outcomes to understand and explain how policy change has occurred. A key advantage of the model is that it increases understanding of network transformation, explanation of which has been an alleged weakness of the policy network approach. However, this case study does throw up some weaknesses with the model, including the tendency of the model to emphasize the role of 'insider' agents and downplay the role of 'outsiders' in the policy process.     

Increasing the ERP signal in the detection of guilty knowledge

The N400 and P300, two event-related potentials (ERPs), were tested using a modified Guilty Knowledge Test for their effectiveness in discriminating people possessing guilty knowledge from those who did not. In the study phase, participants read different passages that detailed either a crime in a specific location (Guilty), some location, without a crime (Innocent but Knowledgeable) or an unrelated location without a crime (Naive). During EEG collection, participants viewed context phrases, some of which were relevant to the crime scene, and test words that were either congruent or incongruent to the context phrases. In Experiment 1, both Guilty and Innocent but Knowledgeable participants were originally classified as guilty because both produced large P300 amplitudes to the crimerelevant stimuli. However, few Innocent but Knowledgeable participants produced significant N400 amplitudes and thus were rejected as guilty in the final analysis. In Experiment 2, participants were assigned to either the Guilty or Innocent but Knowledgeable condition. Seventy-two hours after reading the appropriate passage, participants were divided into two groups: those reminded of the passage read earlier and those who were not. There was not effect of reminding Guilty participants on the discrimination but a strong effect on the Innocent but Knowledgeable participants suggesting a possible technique for discriminating guilty knowledge from other knowledge formats.     

A Legal Semiotics Framework for Exploring the Origins of Hermagorean Stasis

Stasis is a process of classical rhetoric that identifies the core issue in a trial or a similar debate. Hermagoras of Temnos included the first comprehensive analysis of stasis in his second-century BCE treatise on rhetoric, now lost. Modern scholars tend to echo George Kennedy, who maintains that Hermagoras’ inspiration for the hierarchical structure of stasis is indeterminate. This article, however, employs scholarship in legal semiotics, including the work of Miklós K?ncz?l and Bernard S. Jackson, to argue that Hermagoras based stasiastic structure on Aristotle’s first-figure syllogism. Ideally, knowledge of that structure can enhance modern applications of stasis.     

Second-order effects plus pan-European political swings: An analysis of European Parliament elections across time

After seven waves of European Parliament elections and European Union enlargement to 27 states, the time is ripe to analyse the temporal robustness of the second-order model. We pool all the elections in a single evaluation and also look at election-by-election variations. We analyse changes in party performance over time in all EU states as well as in the ‘original 10’, to see whether any cross-time changes are driven by the changing composition of the EU. We also look for pan-European trends in each election, as a way identifying ‘European effects’ distinct from second-order effects. There are few consistent winners and losers, although socialist parties performed worse in the last three elections than their size and government status would predict.     

Interviewing to Detect Deception: When to Disclose the Evidence?

Research shows that there are few objective cues to deception. However, it may be possible to create such cues by strategic interviewing techniques. Strategic Use of Evidence (SUE) is one such technique. The basic premise of the SUE technique is that liars and truth tellers employ different counter-interrogation strategies, and that the evidence against the suspect can be used to exploit these differences in strategies. This study examined the effect of the timing of evidence disclosure (early vs. late vs. gradual) on verbal cues to deception. We predicted that late disclosure would be most effective in differentiating between liars and truth-tellers, and that cues to deception in the gradual disclosure condition would progressively disappear due to the suspects’ realization that evidence against them exists. That is, we expected that liars in the gradual presentation condition would become more consistent with the evidence over time. A sample of 86 undergraduate students went through a mock-terrorism paradigm (half innocent, half guilty), and were subsequently interviewed using one of three disclosure strategies: early, gradual, and late disclosure. We measured statement-evidence inconsistencies as cues to deception . Results supported our predictions in that cues to deception were most pronounced in the late disclosure condition. Contrary to our expectations, the results suggested that presenting the evidence gradually may put innocent suspects at a higher risk of misclassification as they seem to adopt a strategy that is more similar to guilty suspects.
