An improved method for the determination of dissolved nitric oxide (NO) in seawater samples

Nitric oxide (NO) is a short-lived intermediate of the oceanic nitrogen cycle, however, due to its high reactivity, measurements of dissolved NO in seawater are rare. Here we present an improved method to determine NO concentrations in discrete seawater samples. The set-up of our system consisted of a chemiluminescence NO analyser connected to a stripping unit. The limit of detection for our method was 5 pmol NO in aqueous solution which translates into 0.25 nmol L−1 when using a 20 mL seawater sample volume. Our method was applied to measure high resolution depth profiles of dissolved NO during a cruise to the eastern tropical South Pacific Ocean. Our method is fast and comparably easy to handle thus it opens the door for deciphering the distribution of NO in the ocean and it facilitates laboratory studies on NO pathways

A long-lasting controversy : Western democracy promotion in Jordan

Since the end of the cold war and, in particular, the Al Qaeda attacks of 11 September 2001 in the United States, Western governments have in their rhetoric stressed democratization in the Middle East and North Africa (MENA) region as a key policy goal. 1 The EU, the US and other Western countries have developed and extended their democracy promotion activities in the region, in particular democracy assistance to civil society, independent media, the judiciary, parliament and political parties. 2 Such assistance has at times been complemented with public criticism of perceived non-democratic behaviour and political conditionalities, i.e. making democratic reform a precondition for granting favours such as trade deals and development assistance.peer-reviewe

The Paradox of Gendarmeries

This paper describes and explains the evolution of gendarmerie-type forces, i.e. police forces with a military status, over the past three decades. It focuses on their institutional features and functions, including material and human resources, and uses case studies from Europe, the Middle East and North Africa to illustrate these characteristics in different contexts. The overall development of gendarmeries has been a somewhat paradoxical one. On the one hand, most of these forces have witnessed a considerable expansion, and come to assume an increasingly prominent role in addressing many of the currently most important security challenges, ranging from border control and counterterrorism to public order tasks in international peace operations. On the other hand, there has also been a trend towards the demilitarization of gendarmeries, which in some European countries has ultimately led to their dissolution and integration into the civilian police. The paper suggests an explanation of these seemingly contradictory developments with reference to two broad â and at least partly opposing â trends: the convergence of internal and external security agendas, which to a large extent is a post-Cold War phenomenon; and the demilitarization of internal security, which is a more long-term historical trend and part of the more general democratization process. Based on this analysis, the paper predicts that in the long run gendarmeries are likely to be further demilitarized, eventually losing their formal military status, although in the context of international peace operations militarized gendarmerie forces are expected to play an increasingly significant part

Arab Uprisings and Armed Forces

Since late 2010, an unprecedented wave of protests has swept across much of the Arab world. The aim of this paper is to examine the role of the armed forces when confronted with anti-regime uprisings that demand greater political freedoms or even regime change. Drawing on the cases of Tunisia, Egypt, Libya, Bahrain, Yemen and Syria, it argues that the degree of institutionalization of the armed forces and their relationship to society at large can account for different responses to pro-reform uprisings

Security Systems in Francophone and Anglophone Africa

This article analyses the commonalities and differences between African anglophone and francophone security systems in the context of security sector reform. Although each country has a distinct political history and tradition, similarities in the security apparatus, rooted in its inheritance from the colonial and post?colonial periods, can be found in both sets of countries. Identifying better ways to harmonise the SSR programmes being implemented all over the African continent requires a deep understanding of the similarities and differences which exist between African countries that belong to different linguistic areas and inherited from colonial rule. Security governance has been improving in an important number of anglophone countries over the last few years, while Francophone African countries are usually presented as not having experienced any significant transformation in security governance. Influencing factors of relative success or failure include institutional patterns; decision?making structures; type of defence and police forces; and training capacities

A threat to climate-secure European futures? Exploring racial logics and climate-induced migration in US and EU climate security discourses

Whether formulated as a security risk, a form of climate adaptation, a legal dilemma, or an issue of (in)justice, the debate on climate change and migration draws upon multiple, oftentimes contradictory, discourses. This paper examines the role of racial identities in debates about the security implications of climate-induced migration (CIM). The paper proposes a reconceptualization of ‘racial logics’: a form of discursive construction that connects naturalized assumptions about racialized Others with possible outcomes in conditions of future climate insecurity. The paper argues that 'Muslim' and 'African' migrant populations – in the context of possible CIM from the Middle East and North Africa (MENA) region to the EU – are racialized with a potential capacity for radicalization and terrorism. Constructed as racialized Others, 'Muslim' and 'African' migrant populations could face exclusionary containment policies in climate-insecure futures. The article concludes with a call to challenge racial logics and the restrictive, unjust possibilities they suggest for future climate security politics
