[Review of] Raymond T. Smith, ed. Kinship Ideology and Practice in Latin America

Kinship Ideology and Practice in Latin America is a collection of papers resulting from two conferences sponsored by the Joint Committee on Latin American Studies of the American Council of Learned Societies and the Social Science Research Council. The conferences brought together historians, sociologists and anthropologists who were charged with infusing sophisticated social theory into research on the family in Latin America

A solar spectroscopic absolute abundance of argon from RESIK

Observations of He-like and H-like Ar (Ar XVII and Ar XVIII) lines at 3.949 Angstroms and 3.733 Angstroms respectively with the RESIK X-ray spectrometer on the CORONAS-F spacecraft, together with temperatures and emission measures from the two channels of GOES, have been analyzed to obtain the abundance of Ar in flare plasmas in the solar corona. The line fluxes per unit emission measure show a temperature dependence like that predicted from theory, and lead to spectroscopically determined values for the absolute Ar abundance, A(Ar) = 6.44 pm 0.07 (Ar XVII) and 6.49 pm 0.16 (Ar XVIII) which are in agreement to within uncertainties. The weighted mean is 6.45 pm 0.06, which is between two recent compilations of the solar Ar abundance and suggest that the photospheric and coronal abundances of Ar are very similar.Comment: 4 figure

The impact of LASPO on routes to justice

This research underlines the emotional, social, financial and mental health impacts for individuals who have attempted to resolve their legal problems without legal aid, following the implementation of the Legal Aid, Sentencing and Punishment of Offenders Act (LASPO) in 2013. LASPO introduced funding cuts to legal aid and narrowed the scope and financial eligibility criteria, with the result that fewer people could access legal advice and representation for problems in areas such as family, employment and welfare benefits law. We interviewed over 100 people in the Liverpool City Region, with problems in at least one of these areas of law, to understand how LASPO had affected their options for resolving those issues. We also interviewed a number of advice providers and legal aid practitioners, and analysed national data from Citizens Advice. Many participants reported significant financial deprivation as a result of trying but not being able to resolve their legal issues. Some were unable to afford food, adequate housing or other essentials. A lack of preventive legal help led to delays in resolution, which often made problems worse. There was also evidence that costs were passed to other parts of the public sector, including an increased reliance on welfare benefits as a result of unresolved employment issues. Family law • The high cost of legal fees is a key barrier to justice. Some participants who paid for legal advice or representation reported going into debt as a result. • People’s inability to pay for expert or specialist evidence without legal aid may have led to courts making decisions on the basis of insufficient information. • Cuts to legal aid have had a negative impact on children’s lives, especially in relation to child contact cases. Employment law • The main barriers to justice are the high cost of legal representation, the difficulty of navigating the tribunal process without support and a low level of knowledge about employment rights. • Many participants reported that the costs of bringing their claims to tribunal were disproportionate to the value of the claims. This deterred them from bringing claims and made it harder to find a solicitor willing to take their case. • Participants had fewer options for accessing third-sector specialist advice and representation. Those participants who went to tribunal had to represent themselves as a result, and in general they lacked the skills or experience to do this competently. Welfare benefits law • LASPO has significantly reduced the capacity of voluntary sector organisations to provide welfare law advice. There is almost no specialist advice left to provide support to appeal benefits decisions. • The removal of welfare benefits law from the scope of legal aid has exacerbated the impact of recent welfare reforms, which is likely to have affected disabled people disproportionately. Most participants tried multiple routes to resolve a single issue: attempting to resolve problems on their own, trying to access free advice and taking steps to get paid advice or representation before courts or tribunals. But without legal aid, almost all the participants struggled to solve their problems

Decolonising the curriculum is an ongoing and collective effort: Responding to Townsend (2020) and Gibson and Farias (2020)

This paper responds to Townsend (2020), and Gibson and Farias (2020), who were invited to write commentaries regarding Simaan’s (2020) ‘Decolonising occupational science education through learning activities based on a study from the Global South’. My reply acknowledges work done by scholars in the Global North and South, both in and outside occupational science, that critiques Western-centric hegemony in academia. It recognises the multiple aspects of decolonial work in occupational science education, and its collective and continuous nature. I argue that my objective of stimulating reflections and discussion about decolonising occupational science education and knowledge has been achieved by this collective effort to extend this discourse. Future reflections, research, and activism in this area are of paramount importance if we are to truly decolonise occupational science

Outcomes of specialist discharge coordination and intermediate care schemes for patients who are homeless: analysis protocol for a population-based historical cohort

Introduction People who are homeless often experience poor hospital discharge arrangements, reflecting ongoing care and housing needs. Specialist integrated homeless health and care provision (SIHHC) schemes have been developed and implemented to facilitate the safe and timely discharge of homeless patients from hospital. Our study aims to investigate the health outcomes of patients who were homeless and seen by a selection of SIHHC services. Methods and analysis Our study will employ a historical population-based cohort in England. We will examine health outcomes among three groups of adults: (1) homeless patients seen by specialist discharge schemes during their hospital admission; (2) homeless patients not seen by a specialist scheme and (3)admitted patients who live in deprived neighbourhoods and were not recorded as being homeless. Primary outcomes will be: time from discharge to next hospital inpatient admission; time from discharge to next accident and emergency attendance and 28-day emergency readmission. Outcome data will be generated through linkage to hospital admissions data (Hospital Episode Statistics) and mortality data for November 2013 to November 2016. Multivariable regression will be used to model the relationship between the study comparison groups and each of the outcomes. Ethics and dissemination Approval has been obtained from the National Health Service (NHS) Confidentiality Advisory Group (reference 16/CAG/0021) to undertake this work using unconsented identifiable data. Health Research Authority Research Ethics approval (REC 16/EE/0018) has been obtained in addition to local research and development approvals for data collection at NHS sites. We will feedback the results of our study to our advisory group of people who have lived experience of homelessness and seek their suggestions on ways to improve or take this work further for their benefit. We will disseminate our findings to SIHHC schemes through a series of regional workshops

Using coloured filters to reduce the symptoms of visual stress in children with reading delay

Background: Meares Irlen Syndrome (MIS), otherwise known as “visual stress”, is one condition that can cause difficulties with reading. Aim: This study aimed to compare the effect of two coloured-filter systems on the symptoms of visual stress in children with reading delay. Methods: The study design was a pre-test, post-test, randomized head-to-head comparison of two filter systems on the symptoms of visual stress in school children. A total of 68 UK mainstream schoolchildren with significant impairment in reading ability completed the study. Results: The filter systems appeared to have a large effect on the reported symptoms between pre and post three-month time points (d = 2.5, r = 0.78). Both filter types appeared to have large effects (Harris d = 1.79, r = 0.69 and DRT d = 3.22, r = 0.85). Importantly, 35% of participants’ reported that their symptoms had resolved completely; 72% of the 68 children appeared to gain improvements in three or more visual stress symptoms. Conclusion and significance: The reduction in symptoms, which appeared to be brought about by the use of coloured filters, eased the visual discomfort experienced by these children when reading. This type of intervention therefore has the potential to facilitate occupational engagement

However, proxy data representing the event are only available from select marine and terrestrial sedimentary sequences that are unevenly distributed across Earth’s surface, limiting our view of the spatial patterns of climate change. Here, we use paleoclimate data assimilation (DA) to combine climate model and proxy information and create a spatially complete reconstruction of the PETM and the climate state that precedes it (“PETM-DA”). Our data-constrained results support strong polar amplification, which in the absence of an extensive cryosphere, is related to temperature feedbacks and loss of seasonal snow on land. The response of the hydrological cycle to PETM warming consists of a narrowing of the Intertropical Convergence Zone, off-equatorial drying, and an intensification of seasonal monsoons and winter storm tracks. Many of these features are also seen in simulations of future climate change under increasing anthropogenic emissions. Since the PETM-DA yields a spatially complete estimate of surface air temperature, it yields a rigorous estimate of global mean temperature change (5.6 ∘C; 5.4 ∘C to 5.9 ∘C, 95% CI) that can be used to calculate equilibrium climate sensitivity (ECS). We find that PETM ECS was 6.5 ∘C (5.7 ∘C to 7.4 ∘C, 95% CI), which is much higher than the present-day range. This supports the view that climate sensitivity increases substantially when greenhouse gas concentrations are high.Publisher PDFPeer reviewe

Microbiome profiling by Illumina sequencing of combinatorial sequence-tagged PCR products

We developed a low-cost, high-throughput microbiome profiling method that uses combinatorial sequence tags attached to PCR primers that amplify the rRNA V6 region. Amplified PCR products are sequenced using an Illumina paired-end protocol to generate millions of overlapping reads. Combinatorial sequence tagging can be used to examine hundreds of samples with far fewer primers than is required when sequence tags are incorporated at only a single end. The number of reads generated permitted saturating or near-saturating analysis of samples of the vaginal microbiome. The large number of reads al- lowed an in-depth analysis of errors, and we found that PCR-induced errors composed the vast majority of non-organism derived species variants, an ob- servation that has significant implications for sequence clustering of similar high-throughput data. We show that the short reads are sufficient to assign organisms to the genus or species level in most cases. We suggest that this method will be useful for the deep sequencing of any short nucleotide region that is taxonomically informative; these include the V3, V5 regions of the bac- terial 16S rRNA genes and the eukaryotic V9 region that is gaining popularity for sampling protist diversity.Comment: 28 pages, 13 figure

What are the living conditions and health status of those who don't report their migration status? a population-based study in Chile

BACKGROUND: Undocumented immigrants are likely to be missing from population databases, making it impossible to identify an accurate sampling frame in migration research. No population-based data has been collected in Chile regarding the living conditions and health status of undocumented immigrants. However, the CASEN survey (Caracterizacion Socio- Economica Nacional) asked about migration status in Chile for the first time in 2006 and provides an opportunity to set the base for future analysis of available migration data. We explored the living conditions and health of self-reported immigrants and respondents who preferred not to report their migration status in this survey. METHODS: Cross-sectional secondary analysis of CASEN survey in Chile in 2006. Outcomes: any disability, illness/accident, hospitalization/surgery, cancer/chronic condition (all binary variables); and the number of medical/emergency attentions received (count variables). Covariates: Demographics (age, sex, marital status, urban/rural, ethnicity), socioeconomic status (education level, employment status and household income), and material standard of living (overcrowding, sanitation, housing quality). Weighted regression models were estimated for each health outcome, crude and adjusted by sets of covariates, in STATA 10.0. RESULTS: About 1% of the total sample reported being immigrants and 0.7% preferred not to report their migration status (Migration Status - Missing Values; MS-MV). The MS-MV lived in more deprived conditions and reported a higher rate of health problems than immigrants. Some gender differences were observed by health status among immigrants and the MS-MV but they were not statistically significant. Regressions indicated that age, sex, SES and material factors consistently affected MS-MVs’ chance of presenting poor health and these patterns were different to those found among immigrants. Great heterogeneity in both the MS-MV and the immigrants, as indicated by wide confidence intervals, prevented the identification of other significantly associated covariates. CONCLUSION: This is the first study to look at the living conditions and health of those that preferred not to respond their migration status in Chile. Respondents that do not report their migration status are vulnerable to poor health and may represent undocumented immigrants. Surveys that fail to identify these people are likely to misrepresent the experiences of immigrants and further quantitative and qualitative research is urgently required
