In late March and early April, the US Air Forces in Europe (USAFE) held an exercise in Estonia, during which US F-16s destroyed ground targets in an Estonian firing range. Around the same time the Americans held a drill with the Swedish and Finnish Air Forces over the Baltic Sea. The United States has been playing a leading role in the process of strengthening NATO’s presence in the Baltic states. As far as the Western European allies are concerned, Germany will follow in the footsteps of Denmark and the United Kingdom, both of which made significant military contributions to the strengthening of the allied presence in 2014, and will deploy the largest number of troops in 2015. Non-aligned Sweden and Finland, key for the performance of NATO operations in the Baltic states, have been emphasising their military and political readiness to co-operate with NATO in the event of potential crises or conflicts. Comparing NATO ‘s military presence in the Baltic states before and after the outbreak of the Russian intervention in Ukraine, it is clear that NATO has stepped up its engagement considerably. However, its scope is still relatively small, given the much larger military potential and mobilisation capacity of Russia. Moreover, the message sent by NATO’s actions may be diminished by the political, military and financial constraints faced by the allies and Sweden and Finland. It seems that the greatest risk to the military security of the Baltic states currently appears to be the possibility that Russia could wrongly assess the reliability of NATO’s security guarantees.

The refugee crisis that unfolded in Europe in the summer of 2015 questions the effectiveness of European border and refugee policies. The breakdown of the Dublin and Schengen rules due to chaotic situations at the borders in the Balkans marks a critical juncture for the EU. We consider this breakdown as a consequence of a long-lasting co-operation crisis among EU Member States. The most recent Council decision responds to this co-operation crisis (Council Decision 12098/15). This Policy Brief analyses EU policy and politics and argues that plans for refugee relocation and reception centres as well as the use of qualified majority voting in the Council can unfold a dynamic that helps to solve the co-operation crisis. However, underlying the problems of co-operation and effectiveness is the EU’s border paradox: while EU border policy works towards refugee deterrence, EU asylum policy aims at refugee protection. The EU’s approach in regulating borders and asylum can be understood in terms of ‘organised hypocrisy’ (Brunsson, 1993). Reconciling the paradox calls for overcoming such hypocrisy.

Rabbitfish Siganus fuscescens preferences for Lyngbya majuscula collected from three bloom locations in Moreton Bay, Queensland, Australia, were tested along with a range of local plant species in the laboratory. Consumption of L. majuscula by fish did not differ between wild and captive-bred fish (P = 0.152) but did differ between bloom location (P = 0.039). No relationship was found between consumption rates and lyngbyatoxin-a concentration (r(2) = 0.035, P = 0.814). No correlation existed between C : N and proportion of food consumed when all food types were analysed statistically, whereas a clear correlation was observed when L. majuscula was removed from the calculations. In simulated bloom conditions, fish avoided ingestion of L. majuscula by feeding through gaps in the L. majuscula coverage. Both wild and captive-bred S. fuscescens showed a distinct feeding pattern in 10 day no-choice feeding assays, with less L. majuscula being consumed than the preferred red alga Acanthophora spicifera. Lyngbya majuscula however, was consumed in equal quantities to A. spicifera by wild S. fuscescens when lyngbyatoxin-a was not detectable. Wild fish probably do not preferentially feed on L. majuscula when secondary metabolites are present and are not severely impacted by large L. majuscula blooms in Moreton Bay. Furthermore, poor feeding performance in both captive-bred and wild S. fuscescens suggests that they would exert little pressure as a top-down control agent of toxic L. majuscula blooms within Moreton Bay.

This study investigates the influence of mesograzer prior exposure to toxic metabolites on palatability of the marine cyanobacterium, Lyngbya majuscula. We examined the palatability of L. majuscula crude extract obtained from a bloom in Moreton Bay, South East Queensland, Australia, containing lyngbyatoxin-a (LTA) and debromoaplysiatoxin (DAT), to two groups: (1) mesograzers of L. majuscula from Guam where LTA and DAT production is rare; and (2) macro- and mesograzers found feeding on L. majuscula blooms in Moreton Bay where LTA and DAT are often prevalent secondary metabolites. Pair-wise feeding assays using artificial diets consisting of Ulva clathrata suspended in agar (control) or coated with Moreton Bay L. majuscula crude extracts (treatment) were used to determine palatability to a variety of consumers. In Guam, the amphipods, Parhyale hawaiensis and Cymadusa imbroglio; the majid crab Menaethius monoceros; and the urchin Echinometra mathaei were significantly deterred by the Moreton Bay crude extract. The sea hares, Stylocheilus striatus, from Guam were stimulated to feed by treatment food whereas S. striatus collected from Moreton Bay showed no discrimination between food types. In Moreton Bay, the cephalaspidean Diniatys dentifer and wild caught rabbitfish Siganus fuscescens were significantly deterred by the crude extract. However, captive-bred S. fuscescens with no known experience with L. majuscula did not clearly discriminate between food choices. Lyngbya majuscula crude extract deters feeding by most mesograzers regardless of prior contact or association with blooms.

In this paper we analyze criminal deterrence in the presence of specific psychic costs of punishments. We consider a dynamic model with three players, analyzing the choices of a representative lawmaker, potential criminal and judge. In our setting the lawmaker decides whether to introduce a fixed punishment enhancement above a chosen threshold of crime level, depending on its popularity among the voters. In reaction, the judge, who is influenced by her own preferences as well as the opinion of her peer group, might change the probability of punishment, through affecting the standard of reasonable doubt. Our results suggest that large discontinuous and mandatory increases in punishment can have unintended effects that are contrary to the stated goal of such punishment enhancements. In equilibrium, when either the judge or her peer group is "anti-punishment" enough, the level of criminal activity might increase in response to the punishment enhancement. This perverse effect is less likely to occur if there is a higher number of peer groups within the "elite", so that a greater extent of self-selection by judges can occur. Our results have relevance for a number of areas outside the traditional criminal justice system as well, such as special courts (such as ecclesiastical or military courts), or the strictness and enforcement of regulations.

Using only legal sanctions to manage the speed at which people drive ignores the potential benefits of harnessing social factors such as the influence of others. Social influences on driver speeds were explored in this qualitative examination of 67 Australian drivers. Focus group interviews with 8 driver types (young, mid-age and older males and females, and self-identified Excessive and Rare speeders) were guided by Akers’ social learning theory (Akers, 1998). Findings revealed two types of influential others: people known to the driver (passengers and parents), and unknown other drivers. Passengers were generally described as having a slowing influence on drivers: responsibility for the safety of people in the car and consideration for passenger comfort were key themes. In contrast, all but the Rare speeders reported increasing their speed when driving alone. Parental role modelling was also described. In relation to other drivers, key themes included speeding to keep up with traffic flow and perceived pressure to drive faster. This ‘pressure’ from others to ‘speed up’ was expressed in all groups and reported strategies for managing this varied. Encouragingly, examples of actual or anticipated social rewards for speeding were less common than examples of social punishments. Three main themes relating to social punishments were embarrassment, breaching the trust of others, and presenting an image of a responsible driver. Impression management and self-presentation are discussed in light of these findings. Overall, our findings indicate scope to exploit the use of social sanctions for speeding and social praise for speed limit compliance to enhance speed management strategies.

Traffic law enforcement is based on deterrence principles, whereby drivers control their behaviour in order to avoid an undesirable sanction. For “hooning”-related driving behaviours in Queensland, the driver’s vehicle can be impounded for 48 hours, 3 months, or permanently depending on the number of previous hooning offences. It is assumed that the threat of losing something of value, their vehicle, will discourage drivers from hooning. While official data shows that the rate of repeat offending is low, an in-depth understanding of the deterrent effects of these laws should involve qualitative research with targeted drivers. A sample of 22 drivers who reported engaging in hooning behaviours participated in focus group discussions about the vehicle impoundment laws as applied to hooning offences in Queensland. The findings suggested that deterrence theory alone cannot fully explain hooning behaviour, as participants reported hooning frequently, and intended to continue doing so, despite reporting that it is likely that they will be caught, and perceiving the vehicle impoundment laws to be extremely severe. The punishment avoidance aspect of deterrence theory appears important, as well as factors over and above legal issues, particularly social influences. A concerning finding was drivers’ willingness to flee from police in order to avoid losing their vehicle permanently for a third offence, despite acknowledging risks to their own safety and that of others. This paper discusses the study findings in terms of the implications for future research directions, enforcement practices and policy development for hooning and other traffic offences for which vehicle impoundment is applied.

This submission has been prepared in response to the Parliamentary Travelsafe Committee's Inquiry into vehicle impoundment for drink drivers to address research relevant to the committee’s investigation into whether: • Drink drivers in Queensland continue to drive illegally after being apprehended by police or disqualified from driving by the courts; • The incidence of repeat drink driving undermines the effectiveness of existing penalties for drink driving offences; and • Vehicle impoundment and/or ignition key confiscation are cost-effective deterrents that will reduce drink driving recidivism, relating to other existing or potential methods of managing offenders.
