• We examine the multidimensional character of migration policy preferences, and whether humanitarian values matter for these preferences. • We conducted a pre-registered conjoint experiment in Colombia in 2021 (N = 2,508), a major host of forced migrants globally. • Colombians favor fewer restrictions on Venezuelans' right to work, healthcare access, family reunification, or location within Colombia. • There is support for placing some restrictions on the number of Venezuelans entering the country and the length of their residence in Colombia. • Respondents holding stronger humanitarian preferences favor fewer restrictions in domains addressing core needs of health, family, and work. What migration policies do people in receiving countries prefer, and to what extent do humanitarian concerns matter for these preferences? Despite sustained scholarly attention to migration attitudes in high-income countries, much less work examines public policy preferences—particularly in low- and middle-income countries that receive most forced migrants globally. While legislators can propose and implement migration policies involving multiple domains that differ in restrictiveness, their choices partly rely on public support that may vary depending on the policy area at stake. This makes understanding preferences for realistic migration policies in a multidimensional manner theoretically and empirically important. In response, we conducted a pre-registered conjoint experiment (N = 2,508) fielded in Colombia, the country that has received the largest share of Venezuelan emigrants who themselves currently comprise one of the world's largest migratory flows. Colombians prefer more open policy options that place either some or no restrictions on Venezuelan migrants' labor market access, ability to bring family members, access to public healthcare, or freedom to choose where they live within Colombia. However, there is support for restrictions on the overall number of Venezuelans allowed to settle in the country, as well as the length of time that Venezuelans are allowed to stay in Colombia. Moreover, respondents holding higher levels of humanitarianism prefer less restrictive policies towards Venezuelans relative to those holding stronger economic and material values—particularly in domains addressing core needs of health, family reunification, and employment. Our study contributes novel and timely evidence of multidimensional migration policy preferences from a highly-impacted case, while also showing how altruistic values relating to humanitarianism selectively matter for these preferences.

How do border security practitioners engage with data and technology, and what difficulties or limitations arise from these engagements? Responding to calls for critically examining how technological ‘solutions’ are enacted, we analyse the notion of e-Borders in the UK context as an assemblage comprising abstract conditions, concrete objects, and agents whose roles often manifest themselves through perceptions and practices. We draw upon interviews with former and currently serving senior staff from the UK Home Office, UK Border Force, intelligence services, and private sector suppliers. Practitioners’ reflections reveal how political, social, and human factors—including intuition and management cultures—both construct the e-Border assemblage and introduce discontinuities and frictions within it. Using a more tightly specified theory of assemblage, we highlight how human agents contribute to datafied phenomena like border control. In total, our study emphasises how assemblages are dynamic, never entirely coherent, and always being re-made. [ABSTRACT FROM AUTHOR]

Stem cells are noted for their ability to self-renew and differentiate into a variety of cell types. Some stem cells, described as totipotent cells, have tremendous capacity to self-renew and differentiate. Embryonic stem cells have pluripotent capacity, able to form tissues of all 3 germ layers but unable to form an entire live being. Research with embryonic stem cells has enabled investigators to make substantial gains in developmental biology, therapeutic tissue engineering, and reproductive cloning. However, with these remarkable opportunities many ethical challenges arise, which are largely based on concerns for safety, efficacy, resource allocation, and methods of harvesting stem cells. Discussing the moral and legal status of the human embryo is critical to the debate on stem cell ethics. Religious perspectives and political events leading to regulation of stem cell research are presented and discussed, with special attention directed toward the use of embryonic stem cells for therapeutic and reproductive cloning. Adult stem cells were previously thought to have a restricted capacity to differentiate; however, several reports have described their plasticity potential. Furthermore, there have been close ties between the behavior of stem cells and cancer cells. True eradication of cancer will require a deeper understanding of stem cell biology. This article was written to inform medical scientists and practicing clinicians across the spectrum of medical education about the research and regulatory issues affecting the future of stem cell therapy.
