EU labour migration policy by other means? The potential impact of EU economic governance reforms on labour migration policymaking. EPC Policy Brief, 13 February 2015

Over the last 15 years, Member States have been quite reluctant to address labour migration issues at EU level. Will the forthcoming years reverse the tide and lead to the developement of ambitious and common actions in this policy field? There are currently no strong signs of such a move towards a greater management of labour migration policy at EU level. However, Yves Pascouau argues in this FIERI Working paper that the deadlock may be broken with the development of new policy tools taking place in the field of economic governance. More precisely, he underlines that recipes adopted to overcome the so-called ‘euro crisis’ may well have an impact on labour migration issues.As a consequence, this could initiate a coordination process which was not called for by home affairs decision-makers.

EU Policies on Mixed Migration Flows in the Mediterranean Sea. EU Centre Singapore Background Brief No. 13, February 2015

The tragic deaths of over 300 people off the coast of Lampedusa in 2013 and many other incidents involving migrants from Middle East and North Africa (MENA) crossing the Mediterranean in order to seek refuge in Europe has led to a European Union (EU) level debate on asylum policies and how to deal with irregular migration. However, no concrete policy has been agreed since the tragic events at Lampedusa in 2013 and continuous crossings that have resulted in many more deaths. This background brief provides an overview of the existing EU policies on asylum seekers and in addressing irregular migration and some of the actions which the relevant Member States take when confronted with continuous flows of irregular migrants. This brief concludes that the EU should delink the rescue of irregular migrants from security concerns, provide a legal basis which offers protection to irregular migrants, and create a transparent working environment in which member states are better able to support each other when dealing with such events.

No Move without Free Movement: The EU-Swiss controversy over quotas for free movement of persons. CEPS Policy Brief No. 331, 23 April 2015

The focus of this Policy Brief is the Swiss referendum of 2014 against ‘mass immigration’ in Switzerland. It identifies the challenges that a quota on EU citizens’ free movement rights to Switzerland would pose to EU-Swiss relations, considering: i) the value of freedom of movement in the EU and its indivisibility from the internal market and other economic freedoms; ii) the specificity of the EU legal system following the Lisbon Treaty that established democratic and judicial accountability mechanisms; iii) the lack of supranational judicial oversight of the EU-Switzerland agreements framework; and iv) the existence of the so-called guillotine mechanism, according to which the termination of the Free Movement Agreement would entail the automatic termination of the other agreements with the EU. The authors set out a number of options and consider their implications for EU-Swiss relations.

What priorities for the new European agenda on migration? CEPS Commentary, 22 April 2015

In the wake of the latest tragic drownings in the Mediterranean, in which some 900 immigrants lost their lives, and with a view to the extraordinary EU Summit on April 23rd, this Commentary argues that any short, medium and long-term EU migration policy priorities should start by unequivocally setting out their founding and operational principles. This step would be closely followed by implementation of effective action on the ground aimed at meeting the realities and alleviating the hardship.

The migration of Ukrainians in times of crisis. OSW COMMENTARY Number 187, 2015-10-19

Before the Russian annexation of Crimea and the outbreak of the conflict in eastern Ukraine, the scale of labour outward migration of Ukrainians had been characterised by a slight downward trend. Back in 2014, an increase in the number of Ukrainians who migrated to Russia was observed, although no similar increase was recorded for EU countries (excluding Poland). The year 2015 brought a more rapid surge in the number of Ukrainians migrating to the EU, again mainly to Poland. Due to the lack of current EU-wide data, estimates can be made based only on data compiled by national statistical offices in countries which are the most popular with Ukrainian migrants. In Poland, as of October 2015 Ukrainians held 52,000 valid residence cards. Much greater migration dynamics have been observed in the case of temporary migration – the number of declarations which enable an individual to take up a temporary job in Poland, issued in the first half of 2015, was a staggering 400,000. This means a more than twofold increase – in the whole of 2014 372,000 declarations were issued to Ukrainian citizens. No similar increase has so far been observed in other EU states, including Italy and the Czech Republic, which have always been popular destinations for Ukrainian migration. In late 2014, 233,000 Ukrainian migrants were registered in Italy (in late 2013 the figure was 191,000), whereas in the Czech Republic the number of Ukrainian migrants remains stable – 104,000 in June 2015.

Migration, prospecting, dispersal? What host movement matters for infectious agent circulation?

Spatial disease ecology is emerging as a new field that requires the integration of complementary approaches to address how the distribution and movements of hosts and parasites may condition the dynamics of their interactions. In this context, migration, the seasonal movement of animals to different zones of their distribution, is assumed to play a key role in the broad scale circulation of parasites and pathogens. Nevertheless, migration is not the only type of host movement that can influence the spatial ecology, evolution, and epidemiology of infectious diseases. Dispersal, the movement of individuals between the location where they were born or bred to a location where they breed, has attracted attention as another important type of movement for the spatial dynamics of infectious diseases. Host dispersal has notably been identified as a key factor for the evolution of host-parasite interactions as it implies gene flow among local host populations and thus can alter patterns of coevolution with infectious agents across spatial scales. However, not all movements between host populations lead to dispersal per se. One type of host movement that has been neglected, but that may also play a role in parasite spread is prospecting, i.e., movements targeted at selecting and securing new habitat for future breeding. Prospecting movements, which have been studied in detail in certain social species, could result in the dispersal of infectious agents among different host populations without necessarily involving host dispersal. In this article, we outline how these various types of host movements might influence the circulation of infectious disease agents and discuss methodological approaches that could be used to assess their importance. We specifically focus on examples from work on colonial seabirds, ticks, and tick-borne infectious agents. These are convenient biological models because they are strongly spatially structured and involve relatively simple communities of interacting species. Overall, this review emphasizes that explicit consideration of the behavioral and population ecology of hosts and parasites is required to disentangle the relative roles of different types of movement for the spread of infectious diseases.

Proximate cues to phases of movement in a highly dispersive waterfowl, anas superciliosa

BACKGROUND: Waterfowl can exploit distant ephemeral wetlands in arid environments and provide valuable insights into the response of birds to rapid environmental change, and behavioural flexibility of avian movements. Currently much of our understanding of behavioural flexibility of avian movement comes from studies of migration in seasonally predictable biomes in the northern hemisphere. We used GPS transmitters to track 20 Pacific black duck (Anas superciliosa) in arid central Australia. We exploited La Niña conditions that brought extensive flooding, so allowing a rare opportunity to investigate how weather and other environmental factors predict initiation of long distance movement toward freshly flooded habitats. We employed behavioural change point analysis to identify three phases of movement: sedentary, exploratory and long distance oriented movement. We then used random forest models to determine the ability of meteorological and remote sensed landscape variables to predict initiation of these phases. RESULTS: We found that initiation of exploratory movement phases is influenced by fluctuations in local weather conditions and accumulated rainfall in the landscape. Initiation of long distance movement phases was found to be highly individualistic with minor influence from local weather conditions. CONCLUSIONS: Our study reveals how individuals utilise local conditions to respond to changes in resource distribution at broad scales. Our findings suggest that individual movement decisions of dispersive birds are informed by the integration of multiple weather cues operating at different temporal and spatial scales.

El rol de las redes de apoyo transnacional en la evolución del régimen de trata de personas en la región del mekong, 2004-2015

Con el fin de la unipolaridad no sólo se fortalecieron mecanismos de gobernanza global como los Regímenes Internacionales, sino también se fortalecieron actores no estatales. A pesar de la importancia que tomaron estos dos elementos aún no existe una teoría que explique exhaustivamente la relación que existe entre ellos. Es por lo anterior que, la investigación busca responder de qué manera el rol de las Redes de Apoyo Transnacional ha incidido en la evolución del régimen de tráfico de personas en la Región del Mekong. Asimismo tiene como objetivo comprender las relación entre el Régimen y las Redes de Apoyo Transnacional a través de la formulación de un caso de estudio basado en metodologías cualitativas, específicamente, en el análisis teórico-constructivista y el análisis de contenido de documentos producidos por actores estatales y no estatales.

Correcting mean-field approximations for birth-death-movement processes

On the microscale, migration, proliferation and death are crucial in the development, homeostasis and repair of an organism; on the macroscale, such effects are important in the sustainability of a population in its environment. Dependent on the relative rates of migration, proliferation and death, spatial heterogeneity may arise within an initially uniform field; this leads to the formation of spatial correlations and can have a negative impact upon population growth. Usually, such effects are neglected in modeling studies and simple phenomenological descriptions, such as the logistic model, are used to model population growth. In this work we outline some methods for analyzing exclusion processes which include agent proliferation, death and motility in two and three spatial dimensions with spatially homogeneous initial conditions. The mean-field description for these types of processes is of logistic form; we show that, under certain parameter conditions, such systems may display large deviations from the mean field, and suggest computationally tractable methods to correct the logistic-type description.

Migration of breast cancer cells : understanding the roles of volume exclusion and cell-to-cell adhesion

We study MCF-7 breast cancer cell movement in a transwell apparatus. Various experimental conditions lead to a variety of monotone and nonmonotone responses which are difficult to interpret. We anticipate that the experimental results could be caused by cell-to-cell adhesion or volume exclusion. Without any modeling, it is impossible to understand the relative roles played by these two mechanisms. A lattice-based exclusion process random-walk model incorporating agent-to-agent adhesion is applied to the experimental system. Our combined experimental and modeling approach shows that a low value of cell-to-cell adhesion strength provides the best explanation of the experimental data suggesting that volume exclusion plays a more important role than cell-to-cell adhesion. This combined experimental and modeling study gives insight into the cell-level details and design of transwell assays.

Travelling waves for a velocity–jump model of cell migration and proliferation

Cell invasion, characterised by moving fronts of cells, is an essential aspect of development, repair and disease. Typically, mathematical models of cell invasion are based on the Fisher–Kolmogorov equation. These traditional parabolic models can not be used to represent experimental measurements of individual cell velocities within the invading population since they imply that information propagates with infinite speed. To overcome this limitation we study combined cell motility and proliferation based on a velocity–jump process where information propagates with finite speed. The model treats the total population of cells as two interacting subpopulations: a subpopulation of left–moving cells, $L(x,t)$, and a subpopulation of right–moving cells, $R(x,t)$. This leads to a system of hyperbolic partial differential equations that includes a turning rate, $\Lambda \ge 0$, describing the rate at which individuals in the population change direction of movement. We present exact travelling wave solutions of the system of partial differential equations for the special case where $\Lambda = 0$ and in the limit that $\Lambda \to \infty$. For intermediate turning rates, $0 < \Lambda < \infty$, we analyse the travelling waves using the phase plane and we demonstrate a transition from smooth monotone travelling waves to smooth nonmonotone travelling waves as $\Lambda$ decreases through a critical value $\Lambda_{crit}$. We conclude by providing a qualitative comparison between the travelling wave solutions of our model and experimental observations of cell invasion. This comparison indicates that the small $\Lambda$ limit produces results that are consistent with experimental observations.

Non-invasive techniques for imaging in-vivo human corneal sub basal nerve mapping and migration rate in diabetic neuropathy

Purpose Corneal confocal microscopy (CCM) is a rapid non-invasive ophthalmic technique, which has been shown to diagnose and stratify the severity of diabetic neuropathy. Current morphometric techniques assess individual static images of the subbasal nerve plexus; this work explores the potential for non-invasive assessment of the wide-field morphology and dynamic changes of this plexus in vivo. Methods In this pilot study, laser scanning CCM was used to acquire maps (using a dynamic fixation target and semi-automated tiling software) of the central corneal sub-basal nerve plexus in 4 diabetic patients with and 6 without neuropathy and in 2 control subjects. Nerve migration was measured in an additional 7 diabetic patients with neuropathy, 4 without neuropathy and in 2 control subjects by repeating a modified version of the mapping procedure within 2-8 weeks, thus facilitating re-identification of distinctive nerve landmarks in the 2 montages. The rate of nerve movement was determined from these data and normalised to a weekly rate (µm/week), using customised software. Results Wide-field corneal nerve fibre length correlated significantly with the Neuropathy Disability Score (r = -0.58, p < 0.05), vibration perception (r = -0.66, p < 0.05) and peroneal conduction velocity (r = 0.67, p < 0.05). Central corneal nerve fibre length did not correlate with any of these measures of neuropathy (p > 0.05 for all). The rate of corneal nerve migration was 14.3 ± 1.1 µm/week in diabetic patients with neuropathy, 19.7 ± 13.3µm/week in diabetic patients without neuropathy, and 24.4 ± 9.8µm/week in control subjects; however, these differences were not significantly different (p = 0.543). Conclusions Our data demonstrate that it is possible to capture wide-field images of the corneal nerve plexus, and to quantify the rate of corneal nerve migration by repeating this procedure over a number of weeks. Further studies on larger sample sizes are required to determine the utility of this approach for the diagnosis and monitoring of diabetic neuropathy.

Cultural safety, diversity and the servicer user and carer movement in mental health research

This study will be of interest to anyone concerned with a critical appraisal of mental health service users’ and carers’ participation in research collaboration and with the potential of the postcolonial paradigm of cultural safety to contribute to the service user research (SUR) movement. The history and nature of the mental health field and its relationship to colonial processes provokes a consideration of whether cultural safety could focus attention on diversity, power imbalance, cultural dominance and structural inequality, identified as barriers and tensions in SUR. We consider these issues in the context of state-driven approaches towards SUR in planning and evaluation and the concurrent rise of the SUR movement in the UK and Australia, societies with an intimate involvement in processes of colonisation. We consider the principles and motivations underlying cultural safety and SUR in the context of the policy agenda informing SUR. We conclude that while both cultural safety and SUR are underpinned by social constructionism constituting similarities in principles and intent, cultural safety has additional dimensions. Hence, we call on researchers to use the explicitly political and self-reflective process of cultural safety to think about and address issues of diversity, power and social justice in research collaboration.
