This article considers how much harm is justified in reaching a given immigration goal. Political philosophers generally overlook this question, focusing on whether states have a right to exclude immigrants in general, rather than whether certain means of exclusion are justified. For example, even if excluding new migrants during a pandemic is justified, shooting at migrants attempting to enter is likely an unjustified means of exclusion. We argue harm against migrants in immigration enforcement must be proportional. Whether harm is proportional is impacted by the level of harm migrants experience relative to the harm immigration control averts; whether migrants are forced to migrate; whether the harm against migrants is intended; and whether the harm is instigated directly by a state vs. a non-state actor. We demonstrate that these claims regarding enforcement have implications for justice in immigration currently overlooked. Moreover, these claims are supported in a sample of citizens of the UK and US, despite general opposition to increasing migration in both countries. Drawing on an original experiment focusing on enforcement, novel in evaluating whether the public's opinions are consistent with the requirements of immigration justice, we demonstrate that opinions on enforcement are consistent with sub-principles of proportionality we present.

AbstractQuantifying sex-specific additive genetic variance (VA) in fitness, and the cross-sex genetic correlation (rA), is prerequisite to predicting evolutionary dynamics and the magnitude of sexual conflict. Further, quantifying VA and rA in underlying fitness components, and genetic consequences of immigration and resulting gene flow, is required to identify mechanisms that maintain VA in fitness. However, these key parameters have rarely been estimated in wild populations experiencing natural environmental variation and immigration. We used comprehensive pedigree and life history data from song sparrows (Melospiza melodia) to estimate VA and rA in sex-specific fitness and underlying fitness components, and to estimate additive genetic effects of immigrants alongside inbreeding depression. We found evidence of substantial VA in female and male fitness, with a moderate positive cross-sex rA. There was also substantial VA in male but not female adult reproductive success, and moderate VA in juvenile survival but not adult annual survival. Immigrants introduced alleles with negative additive genetic effects on local fitness, potentially reducing population mean fitness through migration load, but alleviating expression of inbreeding depression. Our results show that VA for fitness can be maintained in the wild, and be broadly concordant between the sexes despite marked sex-specific VA in reproductive success.

In this article, we analyze anti- and pro-immigrant attitudes expressed following the Essex Lorry Deaths tragedy in October 2019 in Britain, in which 39 Vietnamese immigrants died in a sealed lorry truck on their way to their destination. We apply Structural Topic Modeling, an automated text analysis method, to a Twitter dataset (N = 4,376), to understand public responses to the Lorry Deaths incident. We find that Twitter users' posts were organized into two themes regarding attitudes toward immigrants: (1) migration narratives, stereotypes, and victim identities, and (2) border control. Within each theme, both pro- and anti-immigration attitudes were expressed. Pro-immigration posts reflected counter-narratives that challenged the mainstream media's coverage of the incident and critiqued the militarization of borders and the criminalization of immigration. Anti-immigration posts ranged from reproducing stereotypes about Vietnamese immigrants to explicitly blaming the victims themselves or their families for the deaths. This study demonstrates the uses and limitations of using Twitter for public opinion research by offering a nuanced analysis of how pro-and anti-immigration attitudes are discussed in response to a tragic event. Our research also contributes to a growing literature on public opinion about an often-forgotten immigrant group in the UK, the Vietnamese.

The National Child Development Study (NCDS) is a continuing longitudinal study that seeks to follow the lives of all those living in Great Britain who were born in one particular week in 1958. The aim of the study is to improve understanding of the factors affecting human development over the whole lifespan.

The NCDS has its origins in the Perinatal Mortality Survey (PMS) (the original PMS study is held at the UK Data Archive under SN 2137). This study was sponsored by the National Birthday Trust Fund and designed to examine the social and obstetric factors associated with stillbirth and death in early infancy among the 17,000 children born in England, Scotland and Wales in that one week. Selected data from the PMS form NCDS sweep 0, held alongside NCDS sweeps 1-3, under SN 5565.

Survey and Biomeasures Data (GN 33004):
To date there have been nine attempts to trace all members of the birth cohort in order to monitor their physical, educational and social development. The first three sweeps were carried out by the National Children's Bureau, in 1965, when respondents were aged 7, in 1969, aged 11, and in 1974, aged 16 (these sweeps form NCDS1-3, held together with NCDS0 under SN 5565). The fourth sweep, also carried out by the National Children's Bureau, was conducted in 1981, when respondents were aged 23 (held under SN 5566). In 1985 the NCDS moved to the Social Statistics Research Unit (SSRU) - now known as the Centre for Longitudinal Studies (CLS). The fifth sweep was carried out in 1991, when respondents were aged 33 (held under SN 5567). For the sixth sweep, conducted in 1999-2000, when respondents were aged 42 (NCDS6, held under SN 5578), fieldwork was combined with the 1999-2000 wave of the 1970 Birth Cohort Study (BCS70), which was also conducted by CLS (and held under GN 33229). The seventh sweep was conducted in 2004-2005 when the respondents were aged 46 (held under SN 5579), the eighth sweep was conducted in 2008-2009 when respondents were aged 50 (held under SN 6137) and the ninth sweep was conducted in 2013 when respondents were aged 55 (held under SN 7669).

Four separate datasets covering responses to NCDS over all sweeps are available. National Child Development Deaths Dataset: Special Licence Access (SN 7717) covers deaths; National Child Development Study Response and Outcomes Dataset (SN 5560) covers all other responses and outcomes; National Child Development Study: Partnership Histories (SN 6940) includes data on live-in relationships; and National Child Development Study: Activity Histories (SN 6942) covers work and non-work activities. Users are advised to order these studies alongside the other waves of NCDS.

From 2002-2004, a Biomedical Survey was completed and is available under End User Licence (EUL) (SN 8731) and Special Licence (SL) (SN 5594). Proteomics analyses of blood samples are available under SL SN 9254.

Linked Geographical Data (GN 33497):
A number of geographical variables are available, under more restrictive access conditions, which can be linked to the NCDS EUL and SL access studies.

Linked Administrative Data (GN 33396):
A number of linked administrative datasets are available, under more restrictive access conditions, which can be linked to the NCDS EUL and SL access studies. These include a Deaths dataset (SN 7717) available under SL and the Linked Health Administrative Datasets (SN 8697) available under Secure Access.

Additional Sub-Studies (GN 33562):
In addition to the main NCDS sweeps, further studies have also been conducted on a range of subjects such as parent migration, unemployment, behavioural studies and respondent essays. The full list of NCDS studies available from the UK Data Service can be found on the NCDS series access data webpage.

National Child Development Study: Childhood Data from Birth to Age 16, Sweeps 0-3, 1958-1974:
SN 5565 includes selected data from the Perinatal Mortality Survey (PMS), conducted in 1958. Only those cases which were used in the NCDS, thus forming NCDS Sweep 0, are included here (although the full PMS dataset is held at the UKDA under SN 2137). SN 5565 also includes NCDS Sweeps 1, 2 and 3, conducted in 1965, 1969 and 1974 respectively.

For the birth survey, information was obtained from the mother and from medical records by the midwife. For the purposes of the first three NCDS surveys, information was obtained from parents (who were interviewed by health visitors), head teachers and class teachers (who completed questionnaires), the schools' health service (who carried out medical examinations) and the subjects themselves (who completed tests of ability and, latterly, questionnaires).

In addition, the birth cohort was augmented by including immigrants born in the relevant week in the target sample for the first three follow-ups (NCDS1-3). The latter group was identified from the school registers during tracing. Since 1974 no attempt has been made to include new immigrants in the survey.

The Centre for Longitudinal Studies updated the first six waves of NCDS in late 2006. Improvements made include further data cleaning and the addition of new documentation.

For the third edition (July 2014), a file containing additional variables was deposited and the documentation updated accordingly.

This dataset includes interviews with educational personnel and policy-makers in the adult education sector in the United Kingdom working with vulnerable young adults. The interviews discuss contents of study programmes provided by the organisation, pedagogical approaches, gender equality, life management, social problems, socioeconomic status, and active participatory citizenship. The dataset is a ten-interview sample of the interviews collected in the United Kingdom for the Europe-wide EduMAP project (Adult Education as a Means to Active Participatory Citizenship). FSD's holdings also include data collected in the nine other EduMAP countries in their respective languages (Finland, Turkey, Spain, Romania, Latvia, Hungary, Greece, Germany and Estonia). The EduMAP project was funded by the European Commission's "Horizon 2020" research and innovation programme (ID: 693388). Different interview schemes were used for interviews with educational personnel and educational authorities. In the interviews with educational personnel, the first questions concerned the interviewee's job responsibilities, practices in the organisation, and the types of vulnerable learners with whom the interviewee worked. Teaching practices were discussed as well as special education available at the organisation, the students' economic situation, and the concept of active participatory citizenship. Regarding the organisation's practices, the interviewees were asked about, for instance, the work processes for designing new educational programmes, pedagogical approaches, and learning/teaching methods that they had deemed particularly appropriate for vulnerable learners. Many facets of the organisation's practices were discussed in terms of gender, i.e. how possible gender differences were taken into consideration in teaching. Pedagogical details of the programmes were discussed in more detail with regard to, for instance, learning and teaching methods, contents of lessons, teaching processes, and the students' possibility of giving and receiving feedback. The interviewees were also asked what types of competences educational professionals working with vulnerable learners possess or should possess. Finally, the interviews examined the impact of the programmes from socioeconomic and sociocultural perspectives as well as the perspective of social activity and legal-political awareness. Attendance and graduation rates were also charted as well as suggestions for the improvement of the programmes. The final questions concerned collaboration and networking with other institutions. The interviews with educational authorities and policy-makers focused more on the national influence in educational policy, i.e. developing and implementing policies and legislation regarding vulnerable groups. In addition, these interviews discussed e.g. consulting representatives of vulnerable groups in developing policies, achievements and shortcomings of current educational policies, and the most important issues faced by vulnerable groups that should be taken into consideration in developing policies. Background information includes interview date, id, interviewee sector, gender and region where the organisation is located.
