Hope Comes to Watts: An Educational May Term Experience in Los Angeles
The Hope Comes to Watts program is designed to provide a 3-week May Term experience in Los Angeles, California. Students study the cultural, historical and geographical setting as well as complete pertinent readings to prepare for full-day placements in the Watts Learning Center, a public, charter school setting with elementary and middle school campuses. The Hope College students are paired one-on-one with classroom teachers and/or administrators and are fully immersed the day-to-day life of the school. They also participate in a variety of cultural and service opportunities during this experience
Role of combined prenatal and postnatal paracetamol exposure on asthma development: the Czech ELSPAC study
Background: Prenatal and postnatal paracetamol exposure has been previously associated with asthma development in childhood in Western populations. We explore the association between prenatal and postnatal paracetamol exposure and asthma development in a Central European sample of Czech children, suggesting possible additive effect of the both exposures. Furthermore, since aspirin had been used more widely during study data collection in Central Europe, we also compared asthma development for those exposed to paracetamol and aspirin.
Methods: We used data from 3329 children born in the 1990s as members of the prospective Czech European Longitudinal Study of Pregnancy and Childhood. Data about prenatal and postnatal paracetamol and aspirin exposure, and potential covariates were obtained from questionnaires completed by mothers. Data about incident asthma were obtained from paediatrician health records.
Results: 60.9% of children received paracetamol only postnatally, 1.5% only prenatally and 4.9% of children were exposed both during pregnancy and infancy. Prevalence of asthma in following population was 5% at 11 years. Being exposed to paracetamol both in prenatal and postnatal period was associated with asthma development (unadjusted OR 1.98, 95% CI 1.02 to 3.87). Being exposed only in the postnatal period was also significantly associated with increased risk of asthma. No association between prenatal exposure only and outcome was found. A higher but non-significant risk of asthma was observed for those whose mothers used paracetamol during pregnancy compared with those who used aspirin.
Conclusions: The main findings of this prospective birth cohort study add to previous observations linking prenatal and early postnatal paracetamol exposure to asthma development. However, the magnitude of effect is relatively modest, and therefore, we recommend paracetamol to remain the analgesic and antipyretic of choice throughout pregnancy and early childhood
Early-Life Temperamental Differences as Longitudinal Predictors of Unintentional Injuries
Objective: Unintentional injuries are the leading cause of hospitalization and death among children. Compared to environmental factors, less attention in injury preventive efforts has been paid to how individual characteristics relate to the risk of injury. Using a large prospective cohort, the current study assessed the longitudinal impact of early-life temperament on the cumulative number of injuries until mid-Adolescence. Methods: The data came from the European Longitudinal Study of Pregnancy and Childhood (ELSPAC-CZ). Temperament was evaluated by mothers when children were 3 years old (N = 3,545). The main outcome was the pediatrician-reported sum of child's injuries from age 3 to 15 (seven timepoints). Latent profile analysis (LPA) was used to determine classes based on temperamental dimensions and then extended to a mixture model with a distal count outcome. The covariates included maternal conflict and attachment, sex, family structure, and maternal education. Results: The LPA determined the existence of three classes: shy children (8.1% of the sample; lowest activity/highest shyness), outgoing children (50.8%; highest activity/lowest shyness), and average: children (41.1%; middle values). Results from a mixture model showed that the outgoing temperament was associated with the highest longitudinal risk for injuries, as both average children (IRR = 0.89 [0.80, 0.99]), and the shy children (IRR = 0.80 [0.68, 0.95]) had lower risk. Conclusions: Early childhood temperamental differences can have long-Term effects on injury risk. Highly active children showed the highest risk for future injuries, suggesting that these characteristics make them more likely to be involved in novel and potentially dangerous situations
Association between Stress Urinary Incontinence and Depressive Symptoms after Birth: the Czech ELSPAC Study
The study objectives were to (1) identify risk factors related to stress urinary incontinence (SUI) and
postnatal depression (PD) after birth, and (2) investigate both possible directions of association
between SUI and PD in population-based sample of Czech mothers. 3,701 nulliparous and multiparous
women completed the self-reported questionnaires at 6 weeks and 6 months after birth and were
included into the analyses of this prospective cohort study. Unadjusted and adjusted logistic regressions
examined relationship between SUI a PD accounting for range of other risk factors. During the frst 6
months after birth, 650 mothers (17.6%) developed SUI and 641 (17.3%) displayed signs of PD. The
mode of delivery, parity and higher BMI were associated with SUI. The rate of PD symptoms was higher
in mothers with positive history of prenatal depression, and in divorced or widowed mothers. Both
conditions were associated with worse self-reported health, back pain and stop-smoker status. Initially,
SUI at 6 weeks was slightly, but signifcantly associated with onset of PD at 6 months (OR 1.51, 95%
CI 1.02–2.23) while PD at 6 weeks was not signifcantly related to new cases of SUI at 6 months (OR
1.48, 95% CI 0.91–2.39). After full adjustment these OR reduced to 1.41 and 1.38 (both non-signifcant),
respectively. SUI and PD are common conditions in women postpartum that share some risk factors.
Our study suggests that both directions of their relationship are possible although a larger study is
needed to confrm our fndings
A Pilot Test of Group Based Cognitive Behavioral Therapy to Augment Vocational Services for Persons With Serious Mental Illness: Feasibility and Competitive Work Outcomes
Persons with serious mental illness (SMI) struggle with work functioning even with the assistance of vocational services. The current study sought to address this problem by examining a cognitive-behavioral therapy to augment vocational services. Fifty-two adults with SMI receiving vocational services participated in a pre-post feasibility trial of the Cognitive Behavior Therapy for Work Success (CBTw) intervention. CBTw is a 12-week manualized intervention that addresses cognitive and behavioral factors that impact work functioning. Competitive work outcomes were assessed in the 12 weeks preceding baseline and after the intervention. The results demonstrate strong session attendance and a low attrition rate. There were also significant improvements in work outcomes. Specifically, among participants unemployed at baseline, 50.0% attained work during follow-up. These findings provide preliminary evidence that CBTw may be a feasible intervention to augment vocational services; further controlled research should examine its benefit to work outcomes in people with SMI
Comparing the Costs and Acceptability of Three Fidelity Assessment Methods for Assertive Community Treatment
Successful implementation of evidence-based practices requires valid, yet practical fidelity monitoring. This study compared the costs and acceptability of three fidelity assessment methods: on-site, phone, and expert-scored self-report. Thirty-two randomly selected VA mental health intensive case management teams completed all fidelity assessments using a standardized scale and provided feedback on each. Personnel and travel costs across the three methods were compared for statistical differences. Both phone and expert-scored self-report methods demonstrated significantly lower costs than on-site assessments, even when excluding travel costs. However, participants preferred on-site assessments. Remote fidelity assessments hold promise in monitoring large scale program fidelity with limited resources
p-species integrable reaction-diffusion processes
We consider a process in which there are p-species of particles, i.e.
A_1,A_2,...,A_p, on an infinite one-dimensional lattice. Each particle
can diffuse to its right neighboring site with rate , if this site is not
already occupied. Also they have the exchange interaction A_j+A_i --> A_i+A_j
with rate We study the range of parameters (interactions) for which
the model is integrable. The wavefunctions of this multi--parameter family of
integrable models are found. We also extend the 2--species model to the case in
which the particles are able to diffuse to their right or left neighboring
sites.Comment: 16 pages, LaTe
An interacting spin flip model for one-dimensional proton conduction
A discrete asymmetric exclusion process (ASEP) is developed to model proton
conduction along one-dimensional water wires. Each lattice site represents a
water molecule that can be in only one of three states; protonated,
left-pointing, and right-pointing. Only a right(left)-pointing water can accept
a proton from its left(right). Results of asymptotic mean field analysis and
Monte-Carlo simulations for the three-species, open boundary exclusion model
are presented and compared. The mean field results for the steady-state proton
current suggest a number of regimes analogous to the low and maximal current
phases found in the single species ASEP [B. Derrida, Physics Reports, {\bf
301}, 65-83, (1998)]. We find that the mean field results are accurate
(compared with lattice Monte-Carlo simulations) only in the certain regimes.
Refinements and extensions including more elaborate forces and pore defects are
also discussed.Comment: 13pp, 6 fig
