    No. 23: Labour Migration Trends and Policies in Southern Africa

    Get PDF
    Since 1990, there have been major changes to longstanding patterns of intra-regional labour migration within the Southern African Development Community (SADC). At the same time, new channels of migration to and from the region have opened. Labour migration is now more voluminous, dynamic and complex than it has ever been. This presents policy-makers with considerable opportunities and challenges. In order to understand the exact nature of these challenges, it is important to have a good grasp of current labour migration characteristics and trends. Unfortunately, reliable, accurate and comprehensive data on labour migration is not available. The quality and currency of data varies considerably from country to country. A regional labour migration observatory would make the future writing of an overview of migration trends a much easier task. The primary objectives of this overview of labour migration trends and policy implications is fourfold: (a) to review recent characteristics and trends in labour migration within and from the SADC region. Official statistics as well as recent survey data are drawn on to generate an overall picture of current characteristics and trends in the region; (b) to highlight some of the critical and urgent issues pertaining to labour migration in the region; (c) to discuss the main features of labour migration strategies and policies and legislative and regulatory frameworks in countries covered by the Southern African Development Community (SADC); and (d) to review the prospects for the freer circulation of migrant labour in the Southern African region. This brief focuses primarily on the period since 1990 and restructuring of labour migration in the wake of the collapse of apartheid, new global migration forces, the end of the wars in Mozambique and Angola and the current economic and political situation in Zimbabwe. Although the brief provides an overview of the region as a whole, the report concentrates on the major labour migration channels in the region (from countries such as Lesotho, Swaziland, Malawi, Mozambique and Zimbabwe to South Africa). The report also considers the nature and implications of new migrant movements to and from SADC

    Service Value Chains and Effects of Scale

    This paper generalizes Porter’s notion of the value chain for the analysis of service industries. The generalization entails that the flow and the physical transformation and assembly of goods that are characteristic of manufacturing are generalized into flows and transformation of data and flows and transformation of the physical and mental condition of people that are characteristic of many service industries. Utility is generalized from utilities of forms and function of goods, characteristic of manufacturing, to utilities of time, place, convenience, speed, safety, entertainment, physical and mental wellbeing, knowledge and mental capacity, funding and assurance. The analysis yields a categorization of industries according to central features of the value adding process. Here, the analysis is used to identify sources of (in)efficiency of scale, scope and experience, along the value chain.Service industries;production structure;economy of scale

    Beyond Frozen Conflict Scenarios for the Separatist Disputes of Eastern Europe. CEPS Paperback

    Get PDF
    This book forms part of a wider project on the relations between the European Union and Georgia, Moldova and Ukraine, and in particular the Association Agreements and Deep and Comprehensive Free Trade Areas (DCFTAs) between these three states and the European Union. The wider project was begun in 2015 in the aftermath of the Maidan uprising at the beginning of 2014, which had been provoked when President Yanukovich reneged over the signing of Ukraine’s Association Agreement with the EU. Following Yanukovich’s flight to Russia, the Association Agreement was duly signed later in 2014. The agreements with Georgia, Moldova and Ukraine have a substantial common content, while differing in various details. Overall, they provide an association model of unprecedented extent and depth. Democratic political values are at the heart of the agreements, while the economic content goes far beyond classic free trade agreements to include a wholesale approximation of EU internal market regulatory law. The purpose of our wider project was first of all to explain the complex content of the Association Agreements and DCFTAs, which was achieved in a series of comprehensive handbooks published at www.3dcftas.eu. However, the agreements contain only short and simple articles on conflict prevention and management, without meaningful operational content. This was notwithstanding the fact that the EU considers itself, for its own historical reasons, to have a special vocation in conflict prevention and resolution. In addition, Georgia and Moldova were already the sites of unresolved separatist conflicts originating around the collapse of the Soviet Union three decades ago, namely Abkhazia and South Ossetia in Georgia, and Transdniestria in Moldova, to which we have added the case of the Nagorny Karabakh between Armenia and Azerbaijan. On top of this legacy, the Maidan uprising led to the Russian annexation of Crimea and its hybrid war in the Donetsk and Luhansk oblasts of the Donbas. The Donbas thus joined the old ‘frozen conflicts’. In the light of the above, CEPS took the initiative to examine all five unresolved conflicts, to assess where these disputes seem to be heading, and what different scenarios could be imagined for their future, including how the European Union might become more engaged. Indeed, while none of the conflicts are resolved, none are for that matter ‘frozen’. Our first practical priority was to find an author to undertake a comprehensive study of the Donbas, since conditions there make it practically impossible for any analysts from the government-controlled part of Ukraine or from Europe to safely enter these territories for research purposes. We were therefore very fortunate to find Nikolaus von Twickel who had recently been travelling in the Donbas as part of the OSCE Mission there, and is now an independent analyst. For the other four ‘old’ conflicts we were also most fortunate to bring in Thomas de Waal, who has been a leading scholar of the region for some decades, and was willing to bring the stories of these conflicts up to date. The two authors were able to address the complete set of conflicts with a consistent analytical approach, as will be evident from reading the sets of scenarios. We express our warm appreciation towards Sweden and the Swedish International Development Agency (Sida) for their support to the entire project. This volume looks at future prospects for the string of unresolved conflicts that continue to plague the post-Soviet world. Four of them date back to the period when the USSR began to break up in the late 1980s. A new conflict, with many different elements and some similarities, was added to the list in 2014: the Donbas in eastern Ukraine. The open confrontation between Russia and Ukraine over the Donbas and Crimea not only destroyed relations between Moscow and Kyiv but changed politics across the region, shaking up the dynamics of the four existing protracted territorial conflicts over Abkhazia, Nagorny Karabakh, South Ossetia and Transdniestria. The five post-Soviet conflicts are often called ‘frozen’, but this is a misnomer. Although the peace processes around them often look frozen, the situations themselves are anything but frozen and are constantly changing. Two of them, over the Donbas and Nagorny Karabakh, are either ongoing or close to violence. Each dispute has its own history, character and context, which has grown more distinctive over time and has been further shaped by the confrontation over Ukraine. Each continues to evolve. Here we chart scenarios for how these conflicts may develop further with the aim of focusing policymakers’ thinking on which tendencies are dangerous and which ones can be encouraged. There are many moving parts to these situations and complacency is not an option

    On computing Belyi maps

    Get PDF
    We survey methods to compute three-point branched covers of the projective line, also known as Belyi maps. These methods include a direct approach, involving the solution of a system of polynomial equations, as well as complex analytic methods, modular forms methods, and p-adic methods. Along the way, we pose several questions and provide numerous examples.Comment: 57 pages, 3 figures, extensive bibliography; English and French abstract; revised according to referee's suggestion

    Citizenship deprivation

    Get PDF
    Most critical analyses assess citizenship-deprivation policies against international human rights and domestic rule of law standards, such as prevention of statelessness, non-arbitrariness with regard to justifications and judicial remedies, or non-discrimination between different categories of citizens. This report considers instead from a political theory perspective how deprivation policies reflect specific conceptions of political community. We distinguish four normative conceptions of the grounds of membership in a political community that apply to decisions on acquisition and loss of citizenship status: i) a ‘State discretion’ view, according to which governments should be as free as possible in pursuing State interests when determining citizenship status; ii) an ‘individual choice’ view, according to which individuals should be as free as possible in choosing their citizenship status; iii) an ‘ascriptive community’ view, according to which both State and individual choices should be minimised through automatic determination of membership based on objective criteria such as the circumstances of birth; and iv) a ‘genuine link’ view, according to which the ties of individuals to particular States determine their claims to inclusion and against deprivation while providing at the same time objections against including individuals without genuine links. We argue that most citizenship laws combine these four normative views in different ways, but that from a democratic perspective the ‘genuine link’ view is normatively preferable to the others. The report subsequently examines five general grounds for citizenship withdrawal – threats to public security, non-compliance with citizenship duties, flawed acquisition, derivative loss and loss of genuine links – and considers how the four normative views apply to withdrawal provision motivated by these concerns. The final section of the report examines whether EU citizenship provides additional reasons for protection against Member States’ powers of citizenship deprivation. We suggest that, in addition to fundamental rights protection through EU law and protection of free movement rights, three further arguments could be invoked: toleration of dual citizenship in a political union, prevention of unequal conditions for loss among EU citizens, and the salience of genuine links to the EU itself rather than merely to one of its Member States

    Multispectral Palmprint Recognition Using a Quaternion Matrix

    Get PDF
    Palmprints have been widely studied for biometric recognition for many years. Traditionally, a white light source is used for illumination. Recently, multispectral imaging has drawn attention because of its high recognition accuracy. Multispectral palmprint systems can provide more discriminant information under different illuminations in a short time, thus they can achieve better recognition accuracy. Previously, multispectral palmprint images were taken as a kind of multi-modal biometrics, and the fusion scheme on the image level or matching score level was used. However, some spectral information will be lost during image level or matching score level fusion. In this study, we propose a new method for multispectral images based on a quaternion model which could fully utilize the multispectral information. Firstly, multispectral palmprint images captured under red, green, blue and near-infrared (NIR) illuminations were represented by a quaternion matrix, then principal component analysis (PCA) and discrete wavelet transform (DWT) were applied respectively on the matrix to extract palmprint features. After that, Euclidean distance was used to measure the dissimilarity between different features. Finally, the sum of two distances and the nearest neighborhood classifier were employed for recognition decision. Experimental results showed that using the quaternion matrix can achieve a higher recognition rate. Given 3000 test samples from 500 palms, the recognition rate can be as high as 98.83%

    Next in Line – Romanians at the Gates of the EU (emigrants, border control, legislation)

    The first of May 2004 marked an important date in the history of Europe as a political, geographic, and social entity. After years of negotiations, ten European countries joined the European Union, bringing in their potential and expectations, adding a total population of 75 million people and a territory of 738,000 square kilometres: Poland, Hungary, the Czech Republic, Slovenia, Slovakia, Malta, Cyprus, Estonia, Latvia and Lithuania. The EU will continue its enlargement under the Luxembourg Presidency. The membership treaty with Bulgaria and Romania will be finalised with a view to signature in 25 April 2005, in order to join the EU by 2007. Once it has been signed, this will mark the end of the current accession cycle. Membership negotiations with Croatia should commence on 17 March 2005. In mid-December 2004 EU leaders endorsed eventual Turkish entry into the EU, but said that there could be permanent restrictions on freedom of movement for Turkish workers; earlier, the EU Parliament voted 407-262 in favour of Turkey's entry. Romania feels and acts like a European country. You will rather notice a European flag in Bucharest than in London, for example. Romania is not only a country who makes effort to join the European family, by introducing the necessary legal provisions in the national legislation, but it is already part of one, whole Europe, ruled by law, an area of Freedom, Security and Justice. Romania fights against immigration flows targeting Western Countries and guards the external border of European Union. In the same time, Romanians are spread all over Europe, living there alike other Europeans. Until the European Union Member States will decide that Romania truly deserves to join the family, Romanians have to prove that they do not only feel and act as Europeans, but they truly are EuropeansUE Enlargement, external border, Romania, European migration, labour mobility
