More Social Needs Endorsed by Caregivers of Young Children Experiencing Everyday Discrimination

Background: Both discrimination and social needs are underlying risk factors for poor health outcomes; however, there are no studies looking at how feelings of discrimination impact reporting of social needs in the pediatric health care setting. Objective: To compare caregiver report of social needs and desire for help addressing social needs in the pediatric primary care setting based on respondents’ experiences with discrimination. Methods: We conducted a cross-sectional study of caregivers of children aged 2-5 in an urban primary care setting. Caregivers completed a tool to screen for 15 social needs and desire for help to address these needs, with in-person assistance available. The tool was adapted based on qualitative data with this same population and included items from the PHQ-2, 2-item food insecurity screener, and WE CARE survey. The short version of the “Everyday Discrimination Scale” was also completed, and caregivers were categorized as experiencing everyday discrimination if they responded “rarely”, “sometimes”, or “often” on any of 5 types of discrimination. If caregivers experienced everyday discrimination, they were also asked about perceived basis for discrimination. T-tests were conducted to compare the number of reported social needs and number of needs for which a caregiver desired help between groups based on experience of everyday discrimination and type of discrimination. Results: One hundred seventy-eight caregivers (94% mothers, mean age 32) of diverse racial and ethnic backgrounds (29% white, 61% black; 10% Hispanic) completed the screening tool. Sixty-seven percent had public insurance, and 35% were from households with an annual income below $20,000. Fifty-three percent of caregivers reported everyday discrimination, especially in regards to being treated with less respect and receiving poorer service in stores and restaurants (Figure 1) and most commonly on the basis of race (48%), gender (38%), and age (31%). Both caregivers who endorsed everyday discrimination in general, and those endorsing discrimination specifically by gender and age, reported a significantly higher number of social needs and number of social needs for which they wanted help (Table 1). Conclusions: In an urban population of mostly young Black mothers, the majority endorsed feeling some degree of everyday discrimination. Despite this, caregivers who endorsed feelings of discrimination, especially because of their gender and age, reported more social needs and a greater desire for help addressing these needs. This suggests that caregivers feel comfortable reporting sensitive social needs in the context of a child’s healthcare setting even though they may experience everyday discrimination. These findings may also suggest an association between experienced discrimination and social needs, with both potentially influenced by similar sociodemographic factors

On a Generalization of the Frobenius Number

We consider a generalization of the Frobenius Problem where the object of interest is the greatest integer which has exactly $j$ representations by a collection of positive relatively prime integers. We prove an analogue of a theorem of Brauer and Shockley and show how it can be used for computation.Comment: 5 page

Reduction in ventral striatal activity when anticipating a reward in depression and schizophrenia: a replicated cross-diagnostic finding.

In the research domain framework (RDoC), dysfunctional reward expectation has been proposed to be a cross-diagnostic domain in psychiatry, which may contribute to symptoms common to various neuropsychiatric conditions, such as anhedonia or apathy/avolition. We used a modified version of the Monetary Incentive Delay (MID) paradigm to obtain functional MRI images from 22 patients with schizophrenia, 24 with depression and 21 controls. Anhedonia and other symptoms of depression, and overall positive and negative symptomatology were also measured. We hypothesized that the two clinical groups would have a reduced activity in the ventral striatum when anticipating reward (compared to anticipation of a neutral outcome) and that striatal activation would correlate with clinical measures of motivational problems and anhedonia. Results were consistent with the first hypothesis: two clusters in both the left and right ventral striatum were found to differ between the groups in reward anticipation. Post-hoc analysis showed that this was due to higher activation in the controls compared to the schizophrenia and the depression groups in the right ventral striatum, with activation differences between depression and controls also seen in the left ventral striatum. No differences were found between the two patient groups, and there were no areas of abnormal cortical activation in either group that survived correction for multiple comparisons. Reduced ventral striatal activity was related to greater anhedonia and overall depressive symptoms in the schizophrenia group, but not in the participants with depression. Findings are discussed in relation to previous literature but overall are supporting evidence of reward system dysfunction across the neuropsychiatric continuum, even if the specific clinical relevance is still not fully understood. We also discuss how the RDoC approach may help to solve some of the replication problems in psychiatric fMRI research.Supported by the Wellcome Trust Institutional Strategic Support Fund [097814/Z/11], a MRC Clinician Scientist [G0701911], a Brain and Behavior Research Foundation Young Investigator, and an Isaac Newton Trust award to Dr Murray; an award to Dr Segarra from the Secretary for Universities and Research of the Ministry of Economy and Knowledge of the Government of Catalonia and the European Union; by the University of Cambridge Behavioural and Clinical Neuroscience Institute, funded by a joint award from the Medical Research Council [G1000183]and Wellcome Trust [093875/Z/10/Z]; by awards from the Wellcome Trust [095692] and the Bernard Wolfe Health Neuroscience Fund to Dr. Fletcher, and by the Cambridge NIHR Biomedical Research Centre.This is the final version of the article.

Planar laser-induced fluorescence (PLIF) investigation of hypersonic flowfields in a Mach 10 wind tunnel

Planar laser-induced fluorescence (PLIF) of nitric oxide (NO) was used to visualize four different hypersonic flowfields in the NASA Langley Research Center 31-Inch Mach 10 Air wind tunnel. The four configurations were: (1) the wake flowfield of a fuselage-only X-33 lifting body, (2) flow over a flat plate containing a rectangular cavity, (3) flow over a 70deg blunted cone with a cylindrical afterbody, formerly studied by an AGARD working group, and (4) an Apollo-geometry entry capsule - relevant to the Crew Exploration Vehicle currently being developed by NASA. In all cases, NO was seeded into the flowfield through tubes inside or attached to the model sting and strut. PLIF was used to visualize the NO in the flowfield. In some cases pure NO was seeded into the flow while in other cases a 5% NO, 95% N2 mix was injected. Several parameters were varied including seeding method and location, seeding mass flow rate, model angle of attack and tunnel stagnation pressure, which varies the unit Reynolds number. The location of the laser sheet was as also varied to provide three dimensional flow information. Virtual Diagnostics Interface (ViDI) technology developed at NASA Langley was used to visualize the data sets in post processing. The measurements demonstrate some of the capabilities of the PLIF method for studying hypersonic flows

Young people's attitudes to religious diversity : quantitative approaches from social psychology and empirical theology

This essay discusses the design of the quantitative component of the ‘Young People’s Attitudes to Religious Diversity’ project, conceived by Professor Robert Jackson within the Warwick Religions and Education Research Unit, and presents some preliminary findings from the data. The quantitative component followed and built on the qualitative component within a mixed method design. The argument is advanced in seven steps: introducing the major sources of theory on which the quantitative approach builds from the psychology of religion and from empirical theology; locating the empirical traditions of research among young people that have shaped the study; clarifying the notions and levels of measurement employed in the study anticipating the potential for various forms of data analysis; discussing some of the established measures incorporated in the survey; defining the ways in which the sample was structured to reflect the four nations of the UK, and London; illustrating the potential within largely descriptive cross-tabulation forms of analysis; and illustrating the potential within more sophisticated multivariate analytic models

Placental syncytiotrophoblast constitutes a major barrier to vertical transmission of Listeria monocytogenes.

Listeria monocytogenes is an important cause of maternal-fetal infections and serves as a model organism to study these important but poorly understood events. L. monocytogenes can infect non-phagocytic cells by two means: direct invasion and cell-to-cell spread. The relative contribution of each method to placental infection is controversial, as is the anatomical site of invasion. Here, we report for the first time the use of first trimester placental organ cultures to quantitatively analyze L. monocytogenes infection of the human placenta. Contrary to previous reports, we found that the syncytiotrophoblast, which constitutes most of the placental surface and is bathed in maternal blood, was highly resistant to L. monocytogenes infection by either internalin-mediated invasion or cell-to-cell spread. Instead, extravillous cytotrophoblasts-which anchor the placenta in the decidua (uterine lining) and abundantly express E-cadherin-served as the primary portal of entry for L. monocytogenes from both extracellular and intracellular compartments. Subsequent bacterial dissemination to the villous stroma, where fetal capillaries are found, was hampered by further cellular and histological barriers. Our study suggests the placenta has evolved multiple mechanisms to resist pathogen infection, especially from maternal blood. These findings provide a novel explanation why almost all placental pathogens have intracellular life cycles: they may need maternal cells to reach the decidua and infect the placenta

Wasteland energy-scapes: a comparative energy flow analysis of India's biofuel and biomass economies

Through a comparative energy flow analysis, this paper examines the energy security impacts of growing biofuels on wastelands in South India. India's National Policy on Biofuels claims that wastelands are well suited for biofuel production because they are empty and unused. However, in rural Tamil Nadu, a Prosopis juliflora fuelwood energy economy already exists on these lands and services a mix of rural and urban consumers at household and industrial levels. This Prosopis economy currently provides 2.5–10.3 times more useful energy than would the government's proposed Jatropha curcas biodiesel economy, depending on Jatropha by-product usage. Contrary to the government's claims, growing biofuels on wastelands can weaken, rather than improve, the country's energy security. Further, replacing Prosopis with Jatropha could engender changes in economic and property relations that could further weaken energy security. These findings are not specific to rural Tamil Nadu as Prosopis is widely used as a fuelwood throughout Asia and Africa. Calls to ‘develop’ degraded lands through biofuel promotion similarly exist in these regions. This study underscores the importance of analyzing wasteland-centered biofuel policies at local levels in order to better understand the changes in human–environment relationships resulting from this policy push
