Having a voice and being heard : a scoping review of what current literature tells us is most important to the caregivers, children and social workers involved in kinship foster care

This study was undertaken in order to determine what the existing literature tells us about how children, kinship caregivers and social workers perceive the quality of care provided to children placed in kinship foster homes, using a scoping review methodology. The studies that made up the sample had a range of research questions and purposes, but all discussed to some degree, the views of their study participants – children, kinship caregivers and/or social workers – regarding their understandings of what aspects of quality care were most important to child well-being in kinship foster homes. Findings indicate that social workers tend to focus on child safety and permanency planning, while caregivers and children believe that less concrete elements such as the caregiver\u27s ability to welcome and provide love to the child, the emotional support and care from social workers and the involvement of the child and caregiver in the planning process are just as essential to the provision of quality care as child safety, money and other resources. Findings further suggest that children benefit from feeling welcomed into the kinship home, that they need to feel loved by the caregiver, and that all parties want to have their voices heard and needs supported as much as possible in the decision-making process. Based on the findings of this scoping review, this author posits that working to strengthen or improve the relational and support elements that kinship foster families deem most important to the provision of high quality care will contribute to more successful outcomes for the children in kinship care

Operational rules to manage power consumption for content display

The display is often responsible for a large proportion of the overall power consumed by a device. The total power consumption of a display depends on a number of factors such as the number of pixels that need to be switched on, the color and brightness of the pixels, and the rate at which the on-screen content is updated. Displays that draw high amounts of power can deplete the available power resources of a device relatively quickly, thus shortening the amount of time a user can operate the device without needing to charge or replace the device battery. This disclosure describes techniques to specify and enforce a system of rules that dictate the operation of display pixels while rendering the content to be displayed. The rules describe upper or lower bounds for various pixel-related parameters such as switched on state, color, brightness, refresh rate, etc

Spectropolarimetry of SN 2011dh in M51: geometric insights on a Type IIb supernova progenitor and explosion

We present seven epochs of spectropolarimetry of the Type IIb supernova (SN) 2011dh in M51, spanning 86 days of its evolution. The first epoch was obtained 9 days after the explosion, when the photosphere was still in the depleted hydrogen layer of the stripped-envelope progenitor. Continuum polarization is securely detected at the level of P~0.5% through day 14 and appears to diminish by day 30, which is different from the prevailing trends suggested by studies of other core-collapse SNe. Time-variable modulations in P and position angle are detected across P-Cygni line features. H-alpha and HeI polarization peak after 30 days and exhibit position angles roughly aligned with the earlier continuum, while OI and CaII appear to be geometrically distinct. We discuss several possibilities to explain the evolution of the continuum and line polarization, including the potential effects of a tidally deformed progenitor star, aspherical radioactive heating by fast-rising plumes of Ni-56 from the core, oblique shock breakout, or scattering by circumstellar material. While these possibilities are plausible and guided by theoretical expectations, they are not unique solutions to the data. The construction of more detailed hydrodynamic and radiative-transfer models that incorporate complex aspherical geometries will be required to further elucidate the nature of the polarized radiation from SN 2011dh and other Type IIb supernovae.Comment: Post-proof edit.

The Impact of Responsive Feeding Practice Training on Teacher Feeding Behaviors in Tribal Early Care and Education: The Food Resource Equity and Sustainability for Health (FRESH) Study

Background: Establishing healthy eating habits early affects lifelong dietary intake, which has implications for many health outcomes. With children spending time in early care and education (ECE) programs, teachers establish the daytime meal environment through their feeding practices. Objective: We aimed to determine the effect of a teacher-focused intervention to increase responsive feeding practices in 2 interventions, 1 focused exclusively on the teacher’s feeding practices and the other focused on both the teacher’s feeding practices and a nutrition classroom curriculum, in ECE teachers in a Native American (NA) community in Oklahoma. Methods: Nine tribally affiliated ECE programs were randomly assigned to 1 of 2 interventions: 1) a 1.5-h teacher-focused responsive feeding practice training (TEACHER; n = 4) and 2) TEACHER plus an additional 3-h training to implement a 15-wk classroom nutrition curriculum (TEACHER + CLASS; n = 5). Feeding practice observations were conducted during lunch at 1 table in 1 classroom for 2- to 5-y-olds at each program before and 1 mo after the intervention. The Mealtime Observation in Child Care (MOCC) organizes teacher behaviors into 8 subsections. Descriptive statistics and the Shapiro–Wilk test for normality were calculated. Paired t tests were calculated to determine change in each group. Results: Amean± SD of 5.2 ± 2.0 (total n = 47) children and 1.7 ± 0.5 (total n = 14) teachers/center were observed at baseline, and 5.6 ± 1.7 (total n = 50) children and 1.7 ± 0.7 teachers (total n = 14) were observed/center postintervention. Total MOCC scores (max possible = 10) improved for TEACHER (6.1 ± 0.9 compared with 7.5 ± 0.3, t = 4.12, P = 0.026) but not for TEACHER + CLASS (6.5 ± 0.8 compared with 6.4 ± 1.0, t =−0.11, P = 0.915). No other changes were observed. Conclusions: Teacher intervention–only programs demonstrated improvements in responsive feeding practices, whereas the programs receiving teacher and classroom training did not. Greater burden likely decreased capacity to make changes in multiple domains. We demonstrated the ability to implement interventions in NA ECE. Further research with larger communities is necessary. This trial was registered at clinicaltrials.gov as NCT03251950

SN2012ab: A Peculiar Type IIn Supernova with Aspherical Circumstellar Material

We present photometry, spectra, and spectropolarimetry of supernova (SN) 2012ab, mostly obtained over the course of $\sim 300$ days after discovery. SN 2012ab was a Type IIn (SN IIn) event discovered near the nucleus of spiral galaxy 2MASXJ12224762+0536247. While its light curve resembles that of SN 1998S, its spectral evolution does not. We see indications of CSM interaction in the strong intermediate-width emission features, the high luminosity (peak at absolute magnitude $M=-19.5$), and the lack of broad absorption features in the spectrum. The H$\alpha$ emission undergoes a peculiar transition. At early times it shows a broad blue emission wing out to $-14{,}000$ km $\mathrm{s^{-1}}$ and a truncated red wing. Then at late times ($>$ 100$\,$days) it shows a truncated blue wing and a very broad red emission wing out to roughly $+20{,}000$ km $\mathrm{s^{-1}}$. This late-time broad red wing probably arises in the reverse shock. Spectra also show an asymmetric intermediate-width H$\alpha$ component with stronger emission on the red side at late times. The evolution of the asymmetric profiles requires a density structure in the distant CSM that is highly aspherical. Our spectropolarimetric data also suggest asphericity with a strong continuum polarization of $\sim 1-3$% and depolarization in the H$\alpha$ line, indicating asphericity in the CSM at a level comparable to that in other SNe IIn. We estimate a mass-loss rate of $\dot{M} = 0.050\, {\rm M}_{\odot}\,\mathrm{yr^{-1}}$ for $v_{\rm pre} = 100$$\,$km$\,$$\mathrm{s^{-1}}$ extending back at least 75$\,$yr prior to the SN. The strong departure from axisymmetry in the CSM of SN 2012ab may suggest that the progenitor was an eccentric binary system undergoing eruptive mass loss.Comment: 18 pages, 12 figure

True durability: HIV virologic suppression in an urban clinic and implications for timing of intensive adherence efforts and viral load monitoring.

Although the majority of HIV-infected patients who begin potent antiretroviral therapy should expect long-term virologic suppression, the realities in practice are less certain. Durability of viral suppression was examined to define the best timing of targeted adherence strategies and intensive viral load monitoring in an urban clinic population with multiple challenges to ART adherence. We examined the risk of viral rebound for patients who achieved two consecutive viral loads lower than the lower limit of quantification (LLOQ) within 390 days. For 791 patients with two viral loads below the LLOQ, viral rebound \u3eLLOQ from the first viral load was 36.9 % (95 % CI 32.2-41.6) in the first year, 26.9 % (95 % CI 21.7-32.1) in the year following one year of viral suppression, and 24.6 % (95 % CI 18.4-30.9) in the year following 2 years of viral suppression. However, for patients with CD4 ≥300 cells/µl who had 3-6 years of virologic suppression, the risk of viral rebound was very low. At the population level, the risk of viral rebound in a complex urban clinic population is surprisingly high even out to 3 years. Intensified monitoring and adherence efforts should target this high risk period. Thereafter, confidence in truly durable virologic suppression is improved

Antibodies to C1q in systemic lupus erythematosus: Characteristics and relation to FcγRIIA alleles

Antibodies to C1q in systemic lupus erythematosus: Characteristics and relation to FcγRIIA alleles. Autoantibodies to the collagen-like region of the first complement component (C1qAB) are found in patients with systemic lupus erythematosus (SLE), particularly those with renal disease. In a cohort of 46 SLE patients with diffuse proliferative glomerulonephritis, we found declining C1qAB titers in 77% of treatment responders and in only 38% of treatment non-responders (P < 0.03). To further characterize this autoantibody, we tested 240 SLE patients for the presence of C1qAB. Positive titers were found in 44% of patients with renal disease and 18% of patients without renal disease (χ2 P < 0.0003). Analysis of IgG subclass revealed IgG2 C1qAB alone in 34%, IgG1 C1qAB alone in 20%, and both IgG1 and IgG2 in 46% of patients. Fewer than 10% of patients had measurable titers of IgG3 or IgG4 C1qAB. The pathogenic role of these IgG2-skewed C1qAB may relate to impaired immune complex clearance by the mononuclear phagocyte system: IgG2 antibodies are efficiently recognized by only one IgG receptor, the H131 allele of FcγRIIa (FcγRIIa-H131). In contrast, FcγRIIa-R131, which is characterized by minimal IgG2 binding, has recently been associated with lupus nephritis. In our C1qAB positive patients, the presence of FcγRIIA-R131 was associated with an increased risk for renal disease. Autoantibodies to C1q may have pathogenic significance in SLE patients with genetic defects in the ability to clear IgG2 containing immune complexes
