Hyper-precarious lives : Migrants, work and forced labour in the Global North

This paper unpacks the contested inter-connections between neoliberal work and welfare regimes, asylum and immigration controls, and the exploitation of migrant workers. The concept of precarity is explored as a way of understanding intensifying and insecure post-Fordist work in late capitalism. Migrants are centrally implicated in highly precarious work experiences at the bottom end of labour markets in Global North countries, including becoming trapped in forced labour. Building on existing research on the working experiences of migrants in the Global North, the main part of the article considers three questions. First, what is precarity and how does the concept relate to working lives? Second, how might we understand the causes of extreme forms of migrant labour exploitation in precarious lifeworlds? Third, how can we adequately theorize these particular experiences using the conceptual tools of forced labour, slavery, unfreedom and precarity? We use the concept of ‘hyper-precarity’ alongside notions of a ‘continuum of unfreedom’ as a way of furthering human geographical inquiry into the intersections between various terrains of social action and conceptual debate concerning migrants’ precarious working experiences

Vocal Learning and Auditory-Vocal Feedback

Vocal learning is usually studied in songbirds and humans, species that can form auditory templates by listening to acoustic models and then learn to vocalize to match the template. Most other species are thought to develop vocalizations without auditory feedback. However, auditory input influences the acoustic structure of vocalizations in a broad distribution of birds and mammals. Vocalizations are dened here as sounds generated by forcing air past vibrating membranes. A vocal motor program may generate vocalizations such as crying or laughter, but auditory feedback may be required for matching precise acoustic features of vocalizations. This chapter discriminates limited vocal learning, which uses auditory input to fine-tune acoustic features of an inherited auditory template, from complex vocal learning, in which novel sounds are learned by matching a learned auditory template. Two or three songbird taxa and four or ve mammalian taxa are known for complex vocal learning. A broader range of mammals converge in the acoustic structure of vocalizations when in socially interacting groups, which qualifies as limited vocal learning. All birds and mammals tested use auditory-vocal feedback to adjust their vocalizations to compensate for the effects of noise, and many species modulate their signals as the costs and benefits of communicating vary. This chapter asks whether some auditory-vocal feedback may have provided neural substrates for the evolution of vocal learning. Progress will require more precise definitions of different forms of vocal learning, broad comparative review of their presence and absence, and behavioral and neurobiological investigations into the mechanisms underlying the skills.PostprintPeer reviewe

A supermatrix analysis of genomic, morphological, and paleontological data from crown Cetacea

<p>Abstract</p> <p>Background</p> <p>Cetacea (dolphins, porpoises, and whales) is a clade of aquatic species that includes the most massive, deepest diving, and largest brained mammals. Understanding the temporal pattern of diversification in the group as well as the evolution of cetacean anatomy and behavior requires a robust and well-resolved phylogenetic hypothesis. Although a large body of molecular data has accumulated over the past 20 years, DNA sequences of cetaceans have not been directly integrated with the rich, cetacean fossil record to reconcile discrepancies among molecular and morphological characters.</p> <p>Results</p> <p>We combined new nuclear DNA sequences, including segments of six genes (~2800 basepairs) from the functionally extinct Yangtze River dolphin, with an expanded morphological matrix and published genomic data. Diverse analyses of these data resolved the relationships of 74 taxa that represent all extant families and 11 extinct families of Cetacea. The resulting supermatrix (61,155 characters) and its sub-partitions were analyzed using parsimony methods. Bayesian and maximum likelihood (ML) searches were conducted on the molecular partition, and a molecular scaffold obtained from these searches was used to constrain a parsimony search of the morphological partition. Based on analysis of the supermatrix and model-based analyses of the molecular partition, we found overwhelming support for 15 extant clades. When extinct taxa are included, we recovered trees that are significantly correlated with the fossil record. These trees were used to reconstruct the timing of cetacean diversification and the evolution of characters shared by "river dolphins," a non-monophyletic set of species according to all of our phylogenetic analyses.</p> <p>Conclusions</p> <p>The parsimony analysis of the supermatrix and the analysis of morphology constrained to fit the ML/Bayesian molecular tree yielded broadly congruent phylogenetic hypotheses. In trees from both analyses, all Oligocene taxa included in our study fell outside crown Mysticeti and crown Odontoceti, suggesting that these two clades radiated in the late Oligocene or later, contra some recent molecular clock studies. Our trees also imply that many character states shared by river dolphins evolved in their oceanic ancestors, contradicting the hypothesis that these characters are convergent adaptations to fluvial habitats.</p

A Transnational Field Approach to the Study of Labor Trafficking

Labor trafficking has increasingly become a subject of policy and research due to the rise in cross-border mobility and globalization. Whereas labor trafficking is generally approached through a criminal justice frame of transnational organized crime, in this contribution, a broader transnational social field approach is advocated. It is argued that this does more justice to the complex interconnectedness of contemporary reality and allows us to understand better how vulnerability on which human trafficking feeds is created. It is argued that a transnational field approach to labor trafficking allows us to understand better the different forms in which labor trafficking comes and the different ways in which transnational space plays a role in these. The Netherlands is used as an empirical illustration. It is illustrative of how transnational space plays a different role in three types of labor trafficking. For each type, three phases in the labor trafficking process are scrutinized: recruitment, transportation, and the phase of work. It is concluded that it would be helpful to approach labor trafficking not solely from a criminal justice perspective of transnational organized crime but to also include more locally rooted approaches from a labor migration perspective, including a transnational field approach.NWO451-15-025Criminal Justice: Legitimacy, accountability, and effectivit

A new form of union organizing in Japan? Community unions and the case of the McDonald's 'McUnion'

The article examines how and why a new independent trade union was established in McDonald’s Japan in 2006. We discuss these developments both within the McDonald’s ‘system’ and the broader context of the growth of community unions in the Japanese employment system. The findings suggest that the ‘McUnion’ could be seen as a new form of trade union organizing in Japan; unlike an enterprise union it is independent of the employer and recruits ‘non-regular’ workers, yet unlike most community unions is established in one large employer, on a national rather than regional basis, has largely retained its membership and was established and operates with the direct involvement of the main Japanese Trade Union Confederation, Rengo

Self-managing team or tayloristic production chain? What can we learn from simulation-based work design trainings

Digitalisation, flexible job markets, new technologies and innovative forms of collaboration constitute increasing challenges for employers and the design of modern work. But how can we deal with these challenges and what do we know about the effect of good versus bad work design? Based on the job demands-resources model (JRM), we present a simulation-based training during which participants experience the effects of different work characteristics. We focus on the moderating effects of job control and job demands: The JRM assumes that job demands and job control interactively affect employee exhaustion and work engagement: Jobs with high control can buffer the strain-enhancing effect of job demands (buffer hypothesis) and increase work engagement (active learning hypothesis). We test these hypotheses in a workplace simulation during which participants have to produce ice-cream. Our results support the buffer hypothesis but not the active learning hypothesis. We discuss the added value of work design simulations for organisations, practitioners, and HR professionals
