North Africa is changing fast, and its youthful societies look back with pride at their recent uprisings. However, they are also getting frustrated by the fact that the economic outlook is not improving. Europe’s role in the strategically important southern Mediterranean area needs to be realigned in order to promote the development of democracy, employment opportunities, and security. There is a great deal of potential for cooperation with Morocco, Algeria, Tunisia, Libya and Egypt.

From the Introduction. For almost a hundred years (since World War I and the disintegration of the Ottoman Empire) stability – or rather, the permanent threat to stability – has been a key challenge for the Middle East. One of the central elements of this threat has been the so-called Kurdish problem, that is, the issues that continually arise between the states of the region and the Kurdish minority living in the area, as well as the tensions among the individual states caused by a range of issues related to local Kurds. The country most affected by the Kurdish problem is Turkey.

From the Introduction. Russia’s annexation of Crimea and its aggression in eastern Ukraine have triggered a debate about the main directions of defence policy in the Nordic and Baltic region. In the Baltic states, but also in the Nordic countries and Poland, much attention is being paid to questions of Territorial Defence Forces (TDF). TDF are viewed as one of the elements in the national defence systems’ response during the early stages of a hybrid conflict. The Baltic states have decided to adapt their Territorial Defence Forces to new threats by making a number of changes to their functioning, depending on the local conditions in each case. Given the growing uncertainty in the region, they have opted not to undertake any in-depth reforms of TDF at this stage, as that could entail a temporary disorganisation in the armed forces. In the coming years Estonia, Latvia and Lithuania will invest in increasing the size and combat readiness of their Territorial Defence Forces, providing them with better training and equipment, and creating a system of incentives to encourage more people to serve in volunteer formations.

social stressors typically elicit two distinct behavioural responses in vertebrates: an active response (i.e., "fight or flight") or behavioural inhibition (i.e., freezing). Here, we report an interesting exception to this dichotomy in a Caribbean cleaner fish, which interacts with a wide variety of reef fish clients, including predatory species. Cleaning gobies appraise predatory clients as potential threat and become stressed in their presence, as evidenced by their higher cortisol levels when exposed to predatory rather than to non-predatory clients. Nevertheless, cleaning gobies neither flee nor freeze in response to dangerous clients but instead approach predators faster (both in captivity and in the wild), and interact longer with these clients than with non-predatory clients (in the wild). We hypothesise that cleaners interrupt the potentially harmful physiological consequences elicited by predatory clients by becoming increasingly proactive and by reducing the time elapsed between client approach and the start of the interaction process. The activation of a stress response may therefore also be responsible for the longer cleaning service provided by these cleaners to predatory clients in the wild. Future experimental studies may reveal similar patterns in other social vertebrate species when, for instance, individuals approach an opponent for reconciliation after a conflict.

Three studies (N=144) investigated how toddlers aged 18 and 24 months pass the surprise-mark test of self-recognition. In Study 1, toddlers were surreptitiously marked in successive conditions on their legs and faces with stickers visible only in a mirror. Rates of sticker touching did not differ significantly between conditions. In Study 2, toddlers failed to touch a sticker on their legs that had been disguised before being marked. In Study 3, having been given 30-s exposure to their disguised legs before testing, toddlers touched the stickers on their legs and faces at equivalent levels. These results suggest that toddlers pass the mark test based on expectations about what they look like, expectations that are not restricted to the face.

This study documents two different modes of berm development: (I) vertical growth at spring tides or following significant beach cut due to substantial swash overtopping, and (2) horizontal progradation at neap tides through the formation of a proto-berm located lower and further seaward of the principal berm. Concurrent high-frequency measurements of bed elevation and the associated wave runup distribution reveal the details of each of these berm growth modes. In mode I sediment is eroded from the inner surf and lower swash zone where swash interactions are prevalent. The net transport of this sediment is landward only, resulting in accretion onto the upper beach face and over the berm crest. The final outcome is a steepening of the beach face gradient, a change in the profile shape towards concave and rapid vertical and horizontal growth of the berm. In mode 2 sediment is eroded from the lower two-thirds of the active swash zone during the rising tide and is transported both landward and seaward. On the falling tide sediment is eroded from the inner surf and transported landward to backfill the zone eroded on the rising tide. The net result is relatively slow steepening of the beach face, a change of the profile shape towards convex, and horizontal progradation through the formation of a neap berm. The primary factor determining which mode of berm growth occurs is the presence or absence of swash overtopping at the time of sediment accumulation on the beach face. This depends on the current phase of the spring-neap tide cycle, the wave runup height (and indirectly offshore wave conditions) and the height of the pre-existing berm. A conceptual model for berm morphodynamics is presented, based on sediment transport shape functions measured during the two modes of berm growth. (c) 2006 Elsevier B.V. All rights reserved.
