Reproductive migration and population dynamics of the blue crab Callinectes danae in an estuary in southeastern Brazil

Portunid crabs are an important resource in estuaries, and require appropriate management to guarantee their long-term availability. We investigated the population dynamics and reproduction of Callinectes danae in the Estuarine-Bay Complex of Sao Vicente, Sao Paulo, Brazil, to provide basic biological information for public policies for the management of this fishery. Monthly samples were obtained from March 2007 to February 2008 on eight transects, four in the estuary and four in the bay. A total of 2261 specimens (403 males, 1288 females, of which 570 were ovigerous) were collected. Males were significantly larger than females, and the size-frequency distribution was unimodal for males, females and ovigerous females. The sex ratio was nearly always skewed toward females (M:F - 1:4.6). C. danae showed seasonal-continuous reproduction, with high reproductive activity in the warmer season. C. danae breeds in the estuarine-bay complex, with males and juvenile females concentrated in the estuary. After copulation, fertilized females migrate to the estuary entrance and the bay, where ovigerous females are commonly found spawning in high-salinity areas. Therefore, to manage this important economic resource, both the estuary and the bay should be considered for protection, but special attention should be given to the estuary entrance during the summer months, when ovigerous females concentrate.

Educational and Anthropological Perspectives: An Italian View on Migration in Multi-cultural Urban Spaces

In contemporary societies there are different ways to perceive the relation between identity and alterity and to describe the difference between “us” and “them”, residents and foreigners. Anthropologist Sandra Wallman sustains that in multi-cultural urban spaces the frontiers of diversity are not only burdensome markers of identity, but rather they could also represent new chances to define “identity” and “alterity”. These frontiers, in fact, can work like interfaces through which to build time after time, in a creative way, a relationship with the other. From this point of view, the concept of boundary can offer many opportunities to creatively define the relation with the other and to sign new options for cognitive and physical movement. On the other side, in many cases we have a plenty of mechanisms of exclusion that transforms a purely empirical distinction between “us” and “them” in an ontological contrast, as in the case when the immigrant undergoes hostilities through discriminatory language. Even though these forms of racism are undoubtedly objectionable from a theoretical point of view, they are anyway socially “real”, in the sense that they are perpetually reaffirmed and strengthened in public opinion. They are in fact implicit “truths”, realities that are considered objective, common opinions that are part of day-to-day existence. That is the reason why an anthropological prospective including the study of “common sense” should be adopted in our present day studies on migration, as pointed out by American anthropologist Michael Herzfeld. My primary goal is to analyze with such a critical approach same pre-conditions of racism and exclusion in contemporary multi-cultural urban spaces. On the other hand, this essay would also investigate positive strategies of comparing, interchanging, and negotiating alterity in social work. I suggest that this approach can offer positive solutions in coping with “diversity” and in working out policies for recognizing a common identity which, at the same time, do not throw away the relevance of political and economic power.

Book review of “Germany in Transit: Nation and Migration, 1955-2005”. 588 pages, University of California Press, 2007, by Deniz Göktürk, David Gramling and Anton Kaes (eds.)

Though migration is an age-old feature of human activity, driven by various circumstances, its current place in the midst of global dynamics and the phenomenon of globalization is becoming increasingly critical. International immigration and its regulation have been largely shaped by the policies in the receiving countries, often determining preferences for nationality cohorts and work skills to satisfy their labor and human capital requirements. When immigration has been necessitated by political strife, host countries have displayed immense magnanimity as well. However, the growing realization of resource limitations and the strange quirks of cultural pluralism are in turn creating waves of dissonance. Literature and the media are now replete with an in depth look into the immigration debate in various nations of the world in trying to seek new directions and satisfactory solutions.

Do Integration Policies Affect Immigrants' Voluntary Engagement? An Exploration at Switzerland's Subnational Level

This paper investigates whether integration policies influence immigrants' propensity to volunteer, the latter being an important element of immigrants' integration into the host society. By distinguishing different categories of integration policies at Switzerland's subnational level and applying a Bayesian multilevel approach, our results suggest varying policy effects: while policies fostering socio-structural rights enhance immigrants' propensity to volunteer, we observe a negative curvilinear relationship between cultural rights and obligations and immigrants' volunteerism implying that a combination of cultural entitlements and obligations is most conducive to immigrants' civic engagement.

Changing climates, moving people: framing migration, displacement and planned relocation

Different policies are required for different types of human mobility related to climatic changes. Hence, it is necessary to distinguish between migration, displacement and planned relocation in climate policy and operations. The purpose of this Policy Brief is to help distinguish between human migration, displacement and planned relocation and present state-of-the-art thinking about some of the key issues related to addressing these in the context of climate policy.

An International Regulatory Framework for National Employment Policies

Employment-related policies are sensitive by any standard, and they remain basically national despite international labour standards (ILS) being even older than the United Nations. Globalization is changing this situation where countries may have to choose between ‘more’ or ‘better’ jobs. The multilateral framework of the World Trade Organization (WTO) can only have an indirect impact. But Regional Trade Agreements (RTA) and International Investment Agreements (IIA) are emerging as a new way of gradually enhancing the impact of certain labour standards. In addition, unilateral measures both by governments and importers driven by social and environmental consumer preferences and pressure groups increasingly shape the international regulatory framework for national employment policies. Even small, locally operating enterprises risk marginalization and market exclusion by ignoring these developments. The long-term influence of this new ‘network approach’ on employment-related policies, including job location, gender issues, social coherence and migration remains to be seen. Nonetheless, the still flimsy evidence gathered here seems to indicate that this new, international framework might increase sustainable employment where and when supporting measures, including through unilateral preferences and even sanctions, form a ‘cocktail’ which export-oriented industries and their suppliers will find palatable.

On Labor Complementarity, Cultural Frictions and Strategic Immigration Policies

In this paper we consider a model with two industrialized countries that face a flow of immigration from the "rest of the world." The countries differ in three characteristics: the labor complementarity between the "native" population and immigrants, the population size, and the magnitude of the cultural friction between the natives and immigrants. We consider a non-cooperative game between two countries' when their strategic instrument is the choice of an immigration quota and the world immigrant wages introduce the spill-over effect between two countries. We first show that the quota game admits unique pure strategies Nash equilibrium. We then compare the equilibrium choices of two countries and show that even though the larger country attracts more immigrants, it chooses lower quota than its smaller counterpart. It also turns out that higher degree of labor complementarity between natives and immigrants and a lower degree of cultural friction between two groups yield higher immigration quota. We also examine the welfare implications of countries choices' and argue that coordinated and harmonized immigration policies may improve the welfare of both countries.

Authoritarianism and labor market : preference of labor policies in the Arab Gulf countries

Migrant and labor issues are a primary concern in the Arab Gulf countries. With focus on the economic and political conditions that influence actors' decisions when framing labor policies, this study analyzes how preferences of such policies are formed and explains why the governments of the Arab Gulf countries attempt to implement less economical policies. The findings suggest that governments avoid concessions for enterprises required to implement more economical policies and chose uneconomical ones to maintain authoritarian regimes.

Current Challenges regarding the International Refugee Law, with focus on EU Policies and EU Co-operation with UNHCR. CEPS Paper on Liberty and Security in Europe No. 59, September 2013

From an examination of the instruments of the Common European Asylum System (CEAS) and related policy measures regarding border surveillance and migration management, two interrelated issues stand out as particularly sensitive: Access to asylum and responsibility for refugee protection. The prevailing view, supported by UNHCR and others, is that responsibility for the care of asylum seekers and the determination of their claims falls on the state within whose jurisdiction the claim is made. However, the possibility to shift that responsibility to another state through inter-state cooperation or unilateral mechanisms undertaken territorially as well as abroad has been a matter of great interest to EU Member States and institutions. Initiatives adopted so far challenge the prevailing view and have the potential to undermine compliance with international refugee and human rights law. This note reviews EU action in the field by reference to the relevant legal standards and best practices developed by UNHCR, focusing on the specific problems of climate refugees and access to international protection, evaluating the inconsistencies between the internal and external dimension of asylum policy. Some recommendations for the European Parliament are formulated at the end, including on action in relation to readmission agreements, Frontex engagement rules in maritime operations, Regional Protection Programmes, and resettlement.

Liberalising trade in services: creating new migration opportunities? Research Paper in Law, 1/2010

Introduction. It is quite uncommon to associate migration with the rules on services trade. Indeed, all economic definitions of services insist on their immaterial nature and on the increased possibility of trading them ‘virtually’ over networks or else, without any physical movement of the parties involved. Somehow this ‘immaterial’ nature of services reflects on their providers/recipients which seem to be ‘invisible’. Even though most services still require the physical contact of the provider with the recipient1 and, when provided over national borders, do entail migration, service providers and/or recipients are rarely thought of as ‘immigrants’. This may be due to the fact that they enter the foreign territory with a specific aim and, once this aim accomplished, move back to their state of origin; technically they only qualify as short term non-cyclical migrants and are of little interest to policy-makers. A second reason may be that both service providers and recipients are economically desirable: the former are typically highly skilled and trained professionals and the latter are well-off ‘visitors’, increasing consumption in the host state. The legal definition of services in Article 57 TFEU (ex Art. 50 EC) further nourishes this idea about service providers/recipients not being migrants: the relevant Treaty rules only apply when the provisions on free movement of workers and freedom of establishment – themselves clearly linked to migration – do not apply. This distinction has been fleshed up by the ECJ which has consistently held that the distinction between the rules on establishment, on the one hand, and the rules on services, on the other, lies on duration.2 Indeed, all EC manuals state four types of service provision falling under the EC Treaty: a) where the service provider moves to the recipient’s state, for a short period of time (longer stay would amount to establishment), b) where the service recipients themselves move to the state where the service is offered (eg for medical care, education, tourism etc), c) where both service providers and recipients move together in another member state (eg a tourist guide accompanying a group travelling abroad) and d) where the service itself is provided across the borders (typically through the use of ICTs). None of these situations would typically qualify as migration. The above ‘dissociation’ between services and migration has been gradually weakened in the recent years. Indeed, migration is increasingly connected to the transnational provision of services. This is the result of three kinds of factors: developments in the European Court of Justice’s (ECJ) case law; legislative initiatives in the EU; and the GATS. Each one of these is considered in some detail below. The aim of the analysis which follows is to show the extent to which (legislative and judicial) policies aimed at the free provision of services actively affect migration conditions within the EU. The EC rules on the provision of services primarily affect the movement of EU nationals. As it will be shown below, however, third country nationals (TCNs) may also claim the benefits of the rules on services, either as recipients thereof or as employees of some EC undertaking which is providing services in another member state (posted workers).

Migration and Integration. Common Challenges and Responses from Europe and Asia

With the signing of the ASEAN Framework Agreement for the Integration of Priority Sectors (FA) in 2004, migration and integration issues gained significance on the agenda. Primarily concerned with increasing economic growth, this framework excludes the integration of low and unskilled migrant workers; instead, ASEAN efforts to address migration and integration issues have been limited to Mutual Recognition Agreements for skilled labour and professionals. After an analysis of migration policy in the region, we highlight specific barriers to the integration of labour migrants in two priority sectors – nursing, which is highly regulated by the state, and Information, Communications and Technology (ICT), which is typically selfregulated and privately run. Despite a MRA for nursing allowing registered nurses to practice in another ASEAN country under supervision of local nurses without registering with the host country’s nursing regulatory authority, in practice, there are major barriers to the free movement of nurses within ASEAN in terms of skills recognition, licensure requirements and other protectionist measures. Although regulations governing the inflow of ICT professionals are not as stringent as those for healthcare professionals, private costs associated with job search and gaining foreign employment are higher in the ICT sector, largely due to limited information on international mobility within the industry. Three sets of barriers to greater integration are discussed. First, the economic and political diversity within ASEAN makes integration more problematic than in the European Union. Second, the primary concern with value-adding economic growth means that regional agreements are focused on skilled and professional labour migration only. Third, the “ASEAN way” of doing things – via a strong emphasis on consensus and non-interference with domestic policies – often means that the FA provision for the free movement of labour is usually trumped by domestic policies that do not reflect the same desire for labour integration.

Environmental Degradation, Climate Change and Migration: from Research to Policy-Making. IES Policy Brief Issue 2013/08/September 2013

Summary. In recent months, the migratory impacts of environmental degradation and climate change have gained increased worldwide attention. In response to the publication of the EC Staff Working Document on Climate Change, Environmental Degradation and Migration, this policy brief critically outlines current themes and issues that surround this global phenomenon, specifically the findings of current international research which frame the discussions on terminology and current legal, political and institutional conceptual debates. Several proposals were put forward during a Policy Forum in January 2013. Firstly, there is a need for tailored and actionable research outputs that take into account political pressures and realities on the ground. Secondly, migration and climate policies would be clearly boosted through the elaboration of a common policy-oriented research agenda of which elements were put forward at the event. Finally, efficient communication tools and channels could be developed to transfer research findings to policy-makers.

Irregular Migration, Trafficking and Smuggling of Human Beings: Policy Dilemmas in the EU. CEPS Paperback, 22 February 2016

The expert contributors to this edited volume, representing a multidisciplinary selection of academics, examine the treatment of irregular migration, human trafficking and smuggling in EU law and policy. The various chapters explore the policy dilemmas encountered in efforts to criminalise irregular migration and humanitarian assistance to irregular immigrants. The book aims to provide academic input to informed policy-making in the next phase of the European Agenda on Migration. In his Foreword, Matthias Ruete, Director General of DG Home Affairs of the European Commission, writes: “This initiative aims to stimulate evidence-based policy-making and to bring fresh thinking to develop more effective policies. The European Commission welcomes the valuable contribution of this initiative to help close the wide gap in our knowledge about the smuggling of migrants, and especially the functioning of smuggling networks.”
