Relationship Between Self-Report and Observed Parenting Among Parents in Treatment Versus Not in Treatment Populations

Background: Most maltreatment, by definition, is a failure of parenting. However, even without maltreatment, poor parenting can lead to a variety of negative outcomes including social, emotional and behavioral problems. Given that parenting plays a key role in child outcomes, one of the foci of interventions are parenting programs. Interventions for parents must be evaluated using standardized assessment tools, which leads to an important question; how can we best assess parenting? Observational methods (observing a parent and child interact) are often regarded as the gold standard in the assessment of parental behaviors but are cumbersome to administer. Self-reports of parenting behaviors are the most commonly used measure due to ease of administration, but their validity may be questioned. The goal of this study is to examine the relationship between three observational measures of parenting and two self-report measures. Methods: Participants (n=133) were either parents who were receiving treatment at Metro-Atlanta drug courts or other caregivers. All participants completed self-report measures of parenting, and videotaped interaction task with a child. Videos were coded for a variety of behaviors, and two of those behaviors (affection and involvement) matched constructs that parents reported on in a self-report battery. Results: Correlations between self- report and observational measures for the constructs affection and involvement for the whole sample ranged from r = -.03 to.06 for affection, and r = -.05 to .08 for involvement, but none were statistically significant. The relationship between self-report and observed parenting by adult type and child age was also examined. However, none of the correlations were statistically significant. Conclusions: Although there were no significant correlations found between self-report and observational measures, existing research suggests that self-reports are not interchangeable with observational methods. In future studies, constructs used to compare self-reports and observational methods should examine how each relates to the outcomes. Furthermore, CAIC (observational tool) should also be examined in further detail.

Legumes increase grassland productivity with no effect on nitrous oxide emissions

Aims: Grasslands are important agricultural production systems, where ecosystem functioning is affected by land management practices. Grass-legume mixtures are commonly cultivated to increase grassland productivity while reducing the need for nitrogen (N) fertiliser. However, little is known about the effect of this increase in productivity on greenhouse gas (GHG) emissions in grass-legume mixtures. The aim of this study was to investigate interactions between the proportion of legumes in grass-legume mixtures and N-fertiliser addition on productivity and GHG emissions. We tested the hypotheses that an increase in the relative proportion of legumes would increase plant productivity and decrease GHG emissions, and the magnitude of these effects would be reduced by N-fertiliser addition. Methods: This was tested in a controlled environment mesocosm experiment with one grass and one legume species grown in mixtures in different proportions, with or without N-fertiliser. The effects on N cycling processes were assessed by measurement of above- and below-ground biomass, shoot N uptake, soil physico-chemical properties and GHG emissions. Results: Above-ground productivity and shoot N uptake were greater in legume-grass mixtures compared to grass or legume monocultures, in fertilised and unfertilised soils. However, we found no effect of legume proportion on N2O emissions, total soil N or mineral-N in fertilised or unfertilised soils. Conclusions: This study shows that the inclusion of legumes in grass-legume mixtures positively affected productivity, however N cycle were in the short-term unaffected and mainly affected by nitrogen fertilisation. Legumes can be used in grassland management strategies to mitigate climate change by reducing crop demand for N-fertilisers

Rapid desensitization for non-immediate reactions in patients with cystic fibrosis

AbstractNon-immediate hypersensitivity reactions to antibiotics in patients with CF represent a real-life challenge for clinicians. Desensitization is often performed in patients who have exhausted all therapeutic options. Whilst desensitization is an established procedure for immediate reactions we assessed the outcomes and safety of desensitization for non-immediate reactions.We retrospectively reviewed 275 desensitization procedures in 42 patients with a range of non-immediate reactions to six commonly used antibiotics. Desensitization was performed using a 7-step rapid intravenous protocol on a normal medical ward.250 (91%) of overall desensitization procedures were successful; however, this figure incorporates certain individuals having multiple successful procedures. Individual patient success ranged from 55% with tazocin through to 88% with tobramycin. In the 25 patients who failed desensitization the reactions were mild and the majority occurred within 48h of starting treatment. Prophylactic anti-histamines and steroids did not reduce the risk of reaction.Whilst the mechanisms remain uncertain we can confirm that rapid desensitization is a safe and effective way of re-introducing an antibiotic to a patient with a non-immediate reaction

Mental Health Outcomes, Parenting Skills and Family Functioning of Adult and Family Treatment Court Participants

Background: Parental substance use places children at risk for poor social, emotional, and behavioral outcomes. Many parents with substance use disorders (SUD) are treated through accountability drug courts including adult drug courts (ADC) through the criminal justice system and family drug treatment courts (FTC) through the child welfare system. Little is known about the children of parents who participate in treatment through adult drug courts, which could serve as an important treatment venue for improving child outcomes. Children treated through family treatment courts are often the center of treatment. This research compared outcomes of parents and children involved in adult drug and family treatment courts. Methods: Participants were 105 drug court clients (80 from ADC; 25 from FTC) from four Georgia based drug courts. Participants completed computerized interviews containing a variety of measures focusing on adult mental health, parenting behaviors and communication, and child mental health and behavior. Results: Parents in FTC compared to those in ADC reported greater social support (p =.05) and better family functioning (p =.03). Parents in ADC reported poorer parental involvement and poorer monitoring of children than FTC, but no differences in positive parenting (p =.13), inconsistent discipline (p =.27), or child abuse potential (total risk \u3e 9, p =.42; total risk \u3e12, p =.37). Regarding mental health, ADC parents reported a greater number of symptoms or poor mental health than FTC. No differences were found for parent-child communication skills (p =.38), post-traumatic stress symptom severity (p =.62), or child behavior problems. Conclusions: This data suggests that children of caregivers in drug treatment via ADC are at equal and perhaps greater risk than children of caregivers in FTC because of increased parental risk factors. ADC should consider offering family -based treatments that can enhance the parent-child relationship and promote recovery by reducing family conflict

Hydrodynamic dispersion within porous biofilms

Many microorganisms live within surface-associated consortia, termed biofilms, that can form intricate porous structures interspersed with a network of fluid channels. In such systems, transport phenomena, including flow and advection, regulate various aspects of cell behavior by controlling nutrient supply, evacuation of waste products, and permeation of antimicrobial agents. This study presents multiscale analysis of solute transport in these porous biofilms. We start our analysis with a channel-scale description of mass transport and use the method of volume averaging to derive a set of homogenized equations at the biofilm-scale in the case where the width of the channels is significantly smaller than the thickness of the biofilm. We show that solute transport may be described via two coupled partial differential equations or telegrapher's equations for the averaged concentrations. These models are particularly relevant for chemicals, such as some antimicrobial agents, that penetrate cell clusters very slowly. In most cases, especially for nutrients, solute penetration is faster, and transport can be described via an advection-dispersion equation. In this simpler case, the effective diffusion is characterized by a second-order tensor whose components depend on (1) the topology of the channels' network; (2) the solute's diffusion coefficients in the fluid and the cell clusters; (3) hydrodynamic dispersion effects; and (4) an additional dispersion term intrinsic to the two-phase configuration. Although solute transport in biofilms is commonly thought to be diffusion dominated, this analysis shows that hydrodynamic dispersion effects may significantly contribute to transport

The decline in youth drinking in England – is everyone drinking less? A quantile regression analysis

Background and Aims: Youth alcohol consumption has declined significantly over the past 15 years in many high income countries, which may have significant public health benefits. However, if the reductions in drinking occur mostly among lighter drinkers who are at lower risk, then rates of alcohol-related harm among young people today and adults in future may not fall in line with consumption. There is conflicting evidence from Swedish school studies with some suggesting all young people are drinking less while others suggest alcohol consumption among heavier drinkers may be stable or rising while average consumption declines. This paper extends the geographic focus of previous research and examines whether the decline in youth drinking is consistent across the consumption distribution in England. Design: Quantile regression of 15 waves of repeat cross-sectional survey data. Setting: England, 2001-2016. Participants: 31, 882 schoolchildren (50.7% male) aged 11-15 who responded to the Smoking Drinking and Drug Use amongst Young People surveys. Measurements: Past-week alcohol consumption in UK units at each fifth percentile of the consumption distribution. Findings: Reductions in alcohol consumption occurred at all percentiles of the consumption distribution analysed between 2001 and 2016 but the magnitude of the decline differed across percentiles. The decline in consumption at the 90th percentile (β = -.21, CI = -.24, - .18) was significantly larger than among either lighter drinkers at the 50th percentile (β = - .02, CI = -.02, -.01) or heavier drinkers at the 95th percentile (β = -.16, CI = -.18, -.13). Conclusions: Alcohol consumption among young people in England appears to be declining across the consumption distribution, and peaks among heavy drinkers. The magnitude of this decline differs significantly between percentiles of the consumption distribution, with consumption falling proportionally less among the lightest, moderate and very heaviest youth drinkers

Globular Clusters and X-ray Point Sources in Centaurus A (NGC 5128)

We detect 353 X-ray point sources, mostly low-mass X-ray binaries (LMXBs), in four Chandra observations of Centaurus A (NGC 5128), the nearest giant early-type galaxy, and correlate this point source population with the largest available ensemble of confirmed and likely globular clusters associated with this galaxy. Of the X-ray sources, 31 are coincident with 30 globular clusters that are confirmed members of the galaxy by radial velocity measurement (2 X-ray sources match one globular cluster within our search radius), while 1 X-ray source coincides with a globular cluster resolved by HST images. Another 36 X-ray point sources match probable, but spectroscopically unconfirmed, globular cluster candidates. The color distribution of globular clusters and cluster candidates in Cen A is bimodal, and the probability that a red, metal rich GC candidate contains an LMXB is at least 1.7 times that of a blue, metal poor one. If we consider only spectroscopically confirmed GCs, this ratio increases to ~3. We find that LMXBs appear preferentially in more luminous (massive) GCs. These two effects are independent, and the latter is likely a consequence of enhanced dynamical encounter rates in more massive clusters which have on average denser cores. The X-ray luminosity functions of the LMXBs found in GCs and of those that are unmatched with GCs reveal similar underlying populations, though there is some indication that fewer X-ray faint LMXBs are found in globular clusters than X-ray bright ones. Our results agree with previous observations of the connection of GCs and LMXBs in early-type galaxies and extend previous work on Centaurus A.Comment: 34 pages, 10 figures, 2 tables, Accepted for Publication in The Astrophysical Journa
