Authorities’ responses to violence against enslaved Africans: comparisons between eighteenth-century Curaçao and Berbice

This article takes a close look at a small selection of court cases from the Dutch coloniesBerbice (in present-day Guyana) and Curaçao in the eighteenth century, to examine underwhat circumstances and in what ways colonial authorities chose to intervene in violencecommitted against enslaved people. This serves to gain insight into broader attitudes towardsviolence against enslaved people, many instances of which remain obscured in colonialarchives because they were normalized, formally sanctioned, or simply not prioritized bycolonial institutions such as the criminal court. In comparing Curaçao and Berbice, specialattention is given to the specific historical developments and social geography of each colony,which shaped colonial administrators’ concerns and therefore attitudes to violence: when didauthorities decide to intervene, and how did their considerations vary depending on time andplace?Cities, Migration and Global Interdependenc

Regulating relations: controlling sex and marriage in the early modern Dutch empire

Besides trading, the Dutch East India Company (VOC) and its Western Indian counterpart (WIC) also sought to expand their dominant position by establishing and managing colonies. Central to this strategy was to stimulate an orderly, self-producing colonial population, with a European elite at the top and a sharp distinction between free citizens and people in slavery. The reality was less orderly, however: in disparate colonial settlements such as Batavia, Cochin, Ceylon, Elmina, Suriname, Curaçao and Berbice, people from different backgrounds, religions, and social positions encountered one another and formed relationships – formal and informal, coercive and consensual – which could either challenge or reinforce the social divisions on which colonial hierarchies rested. Regulating Relations, focusing on the abovementioned settlements in the eighteenth century, investigates how norms around marriage, family, and sexuality formed in this complex world: how did colonial authorities attempt to regulate the intimate relations of populations under their control, and how did men and women of various backgrounds give shape to these norms through their own behavior and use of institutions?

SL2: an interactive webtool for modeling of missing segments in proteins

SuperLooper2 (SL2) (http://proteinformatics.charite.de/sl2) is the updated version of our previous web-server SuperLooper, a fragment based tool for the prediction and interactive placement of loop structures into globular and helical membrane proteins. In comparison to our previous version, SL2 benefits from both a considerably enlarged database of fragments derived from high-resolution 3D protein structures of globular and helical membrane proteins, and the integration of a new protein viewer. The database, now with double the content, significantly improved the coverage of fragment conformations and prediction quality. The employment of the NGL viewer for visualization of the protein under investigation and interactive selection of appropriate loops makes SL2 independent of third-party plug-ins and additional installations

Mental health in UK Biobank: development, implementation and results from an online questionnaire completed by 157 366 participants

Background UK Biobank is a well-characterised cohort of over 500 000 participants that offers unique opportunities to investigate multiple diseases and risk factors. Aims An online mental health questionnaire completed by UK Biobank participants was expected to expand the potential for research into mental disorders. Method An expert working group designed the questionnaire, using established measures where possible, and consulting with a patient group regarding acceptability. Case definitions were defined using operational criteria for lifetime depression, mania, anxiety disorder, psychotic-like experiences and self-harm, as well as current post-traumatic stress and alcohol use disorders. Results 157 366 completed online questionnaires were available by August 2017. Comparison of self-reported diagnosed mental disorder with a contemporary study shows a similar prevalence, despite respondents being of higher average socioeconomic status than the general population across a range of indicators. Thirty-five per cent (55 750) of participants had at least one defined syndrome, of which lifetime depression was the most common at 24% (37 434). There was extensive comorbidity among the syndromes. Mental disorders were associated with high neuroticism score, adverse life events and long-term illness; addiction and bipolar affective disorder in particular were associated with measures of deprivation. Conclusions The questionnaire represents a very large mental health survey in itself, and the results presented here show high face validity, although caution is needed owing to selection bias. Built into UK Biobank, these data intersect with other health data to offer unparalleled potential for crosscutting biomedical research involving mental health

An assessment of the reliability of three methods used in evaluating the status of multiple sclerosis patients

The reliability of three different evaluation methods used in a cooperative clinical trial of the efficacy of ACTH in multiple sclerosis patients was evaluated in a uniformity study that used an efficient statistical design requiring only 10 patients and 5 examiners. The methods were the standard neurologic examination, a scoring system for functional grades and disability status, and a 7-day symptom score. Each patient was examined only 3 times at the beginning of the study and 3 more times 6 days later. No significant differences among the 5 examiners were observed on 82 of the 87 items used to measure neurologic function. With the exception of 1 variable, there were no significant differences among the average values of the sequence of the 3 examinations, nor among the average increments of change in the numerical scores between the first and second trials.In an additional examination in which all 5 examiners simultaneously evaluated 3 patients 1 at a time, it was found that the 5 examiners observed uniformly in all of the neurologic tests.The results of this study indicate that, by and large, the three evaluation methods appear to be reliable in the evaluation of neurologic status when used in a cooperative clinical trial where several investigators contribute data. Furthermore, investigations of reliability in cooperative studies can be performed with the use of efficient statistical designs such as the incomplete Latin-square design.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32998/1/0000382.pd

Plasma Microparticle Tissue Factor Activity in Patients With Antiphospholipid Antibodies With and Without Clinical Complications

Antiphospholipid syndrome (APS) is defined by the association of autoantibodies to certain phospholipid-binding proteins with arterial or venous thrombosis (‘AT’ or ‘VT’, respectively), and/or pregnancy-related morbidity (PM). Antiphospholipid antibodies (aPLA) promote activation of several cell types including monocytes, resulting in procoagulant tissue factor (TF) expression that may contribute to the vascular complications. Since TF synthesis by monocytes is frequently accompanied by release of TF-bearing microparticles, we hypothesized that plasma microparticle TF activity (MP-TF) may be elevated in APS patients and contribute to thrombosis and/or PM. Platelet-poor plasma specimens were obtained from 30 patients with definite APS and 72 patients with asymptomatic aPLA from the Antiphospholipid Syndrome Collaborative Registry (APSCORE). MP-TF was measured by an in-house factor Xa generation assay. The two groups were well matched for gender, age, ethnicity, proportions with underlying SLE, and aPLA profiles. MP-TF (median and (IQR)) in asymptomatic aPLA subjects was 0.09 pg/mL (0.05–0.14) compared to 0.13 pg/mL (0.10–0.17) in APS (p<0.001). No differences in MP-TF levels were observed between APS subjects with PM, thrombosis, or PM + thrombosis. Similarly, among subjects with either APS or asymptomatic aPLA, MP-TF did not differ in the presence or absence of underlying SLE. Prospective studies will be required to determine if plasma MP-TF activity is causally related to thrombotic or gestational complications in APS

Comparative Study of Multifragmentation of Gold Nuclei Induced by Relativistic Protons, 4^4He, and 12^{12}C

Multiple emission of intermediate-mass fragments has been studied for the collisions of p, $^4$He and $^{12}$C on Au with the $4\pi$ setup FASA. The mean IMF multiplicities (for the events with at least one IMF) are saturating at the value of $2.2\pm0.2$ for the incident energies above 6 GeV. The observed IMF multiplicities cannot be described in a two-stage scenario, a fast cascade followed by a statistical multifragmentation. Agreement with the measured IMF multiplicities is obtained by introducing an intermediate phase and modifying empirically the excitation energies and masses of the remnants. The angular distributions and energy spectra from the p-induced collisions are in agreement with the scenario of ``thermal'' multifragmentation of a hot and diluted target spectator. In the case of $^{12}$C+Au(22.4 GeV) and $^4$He(14.6 GeV)+Au collisions, deviations from a pure thermal break-up are seen in the energy spectra of the emitted fragments, which are harder than those both from model calculations and from the measured ones for p-induced collisions. This difference is attributed to a collective flow.Comment: 33 pages 15 figures, accepted in Nucl. Phys.

Quality improvement dashboard for healthcare providers and targeted client communication to pregnant women to improve timely attendance and quality of antenatal care: A multi-arm cluster randomized trial (the eRegCom trial)

Background: Digital health interventions can strengthen coverage and quality of care. Our aim was to assess the effectiveness of targeted client communication (TCC) to pregnant women via text messages, health care provider communication via a quality improvement dashboard (QID) and the combination of TCC and QID—generated and delivered from a digital maternal and child health registry (MCH eRegistry), running on the District Health Information Software 2 (DHIS2) platform in West Bank and Gaza. The control was the regular MCH eRegistry. Methods: We included 137 clusters in a four-arm cluster randomized controlled trial. Primary outcomes were appropriate screening and management of anemia, hypertension and diabetes during pregnancy, and timely attendance to routine antenatal care (ANC). Results: The COVID-19 pandemic interrupted the trial, which failed to achieve the estimated sample size. Between 1 December 2019 and 23 March 2020, 4138 women attended ANC in the TCC, 3553 in the QID, 4223 in the TCC & QID and 3324 in the control arm. In the TCC arm, 76.5% of the visits were attended timely versus 73.4% in the control arm, (adjusted odds ratio, 1.2; 95% confidence interval, 0.90–1.61). We found no difference between QID and control, or between TCC & QID control in the proportion of visits where anemia, hypertension and diabetes were appropriately screened and managed. Conclusion: The routine individual-level data of the MCH eRegistry enabled the implementation of theory-driven TCC and QID. However, the COVID-19 pandemic interrupted this trial of TCC and QID, and we were unable to observe any significant effect.publishedVersio
