Unaccompanied migrant children and indebted relations: Weaponizing safeguarding

UK statutory guidance for practitioners suggests that indebtedness is an area where safeguarding red flags should be raised and action taken to minimize the risk of exploitation. Yet, our research shows that unaccompanied migrant children have complex indebted relationships, which can range from extractive to connective. Drawing on interviews with unaccompanied children, we show that these indebted relationships can include financial debt to smugglers, responsibilities to support transnational families, as well as social obligations to peers and others. Their accounts present a nuanced understanding of the taboo nature of indebted relationships, not to be shared with the practitioners in their lives. This is due, in part, to the potential threat of reporting to the Home Office, which might jeopardize their immigration status. In response to this weaponization of social care, we demonstrate how children turn to peer networks of support, creating their own alternative forms of social protection. In so doing, we complicate critiques of adultification, which traditionally highlight the ways that racially minoritized children may be treated as adults—to their detriment. In so doing, we show that because indebtedness is normatively linked to adulthood, unaccompanied children's hopes and fears may be rendered unsayable and therefore unsupportable in social care, all in the name of safeguarding

Why do Nigerian manufacturing firms take action on AIDS?

Objective: To identify differences between manufacturing firms in Nigeria that have undertaken HIV/AIDS prevention activities and those that have not as a step toward improving the targeting of HIV policies and interventions. Methods: A survey of a representative sample of registered manufacturing firms in Nigeria, stratified by location, workforce size, and industrial sector. The survey was administered to managers of 232 firms representing most major industrial areas and sectors in March-April 2001. Results: 45.3 percent of the firms’ managers received information about HIV/AIDS from a source outside the firm in 2000; 7.7 percent knew of an employee who was HIV-positive at the time of the survey; and 13.6 percent knew of an employee who had left the firm and/or died in service due to AIDS. Only 31.7 percent of firms took any action to prevent HIV among employees in 2000, and 23.9 percent had discussed the epidemic as a potential business concern. The best correlates of having taken action on HIV were knowledge of an HIV-positive employee or having lost an employee to AIDS (odds ratio [OR] 6.36, 95% confidence interval [CI]: 2.30, 17.57) and receiving information about the disease from an outside source (OR 7.83, 95% CI: 3.46, 17.69). Conclusions: Despite a nationwide HIV seroprevalence of 5.8 percent, as of 2001 most Nigerian manufacturing firm managers did not regard HIV/AIDS as a serious problem and had neither taken any action on it nor discussed it as a business issue. Providing managers with accurate, relevant information about the epidemic and practical prevention interventions might strengthen the business response to AIDS in countries like Nigeria

Nonet Symmetry and Two-Body Decays of Charmed Mesons

The decay of charmed mesons into pseudoscalar (P) and vector (V) mesons is studied in the context of nonet symmetry. We have found that it is badly broken in the PP channels and in the P sector of the PV channels as expected from the non-ideal mixing of the \eta and the \eta'. In the VV channels, it is also found that nonet symmetry does not describe the data well. We have found that this discrepancy cannot be attributed entirely to SU(3) breaking at the usual level of 20--30%. At least one, or both, of nonet and SU(3) symmetry must be very badly broken. The possibility of resolving the problem in the future is also discussed.Comment: 9 pages, UTAPHY-HEP-

A two-layer calculation for the initial interaction region of an unseparated supersonic turbulent boundary layer with a ramp

The interaction of an unseparated supersonic turbulent boundary layer with a compression corner produces an extremely rapid rise in pressure at the corner, followed by a more gradual increase to the final pressure. In this paper, the flow in the corner region is analyzed by an integral method with the objective of predicting the initial pressure rise. Comparisons with experimental pressure rise data are presented for cases covering supersonic and hypersonic flows of practical interest. Also presented are some calculations and comparisons of downstream pressure distributions obtained by using the predicted corner rise as the first point in an existing inviscid method

Research and applications: Artificial intelligence

The program is reported for developing techniques in artificial intelligence and their application to the control of mobile automatons for carrying out tasks autonomously. Visual scene analysis, short-term problem solving, and long-term problem solving are discussed along with the PDP-15 simulator, LISP-FORTRAN-MACRO interface, resolution strategies, and cost effectiveness
