A Qualitative Analysis On The Transitions Of Afghan Refugee Families To The U.s. And Their Parenting Experiences
Introduction: Refugee families can face particularly multifaceted challenges during their transition to the U.S. There is currently little research on the experience of parenting during Afghan refugees’ transitions to the U.S. This study seeks to better understand these individuals’ experiences of parenting and their descriptions of their children’s transitions to the U.S. in the context of the greater New Haven area.
Methods: We conducted a secondary analysis on interview data with 19 recently-arrived Afghan refugee parents based in the greater New Haven area; 10 fathers and 9 mothers were interviewed from August 2019 to January 2020. We used thematic analysis to group codes into larger themes relevant to the research question, ultimately informing the results of this study.
Results: In families’ adjustments to their new home in the U.S., children faced particular challenges related to homesickness, language, and culture, while parents encountered a variety of lingering concerns related to parenting within the new American context. The U.S. resource landscape proved to provide support to both children and parents during the transition. Healthcare and education played especially salient roles in easing the transition for families, serving specifically as potential parenting resources for parents.
Discussion: Generally, it seems that children undergo a necessary initial adjustment period marked by homesickness, language difficulties, and cultural barriers. However, for parents and children alike, numerous challenges during this transition were buffered or improved by the plethora and higher quality of resources in the U.S. At the same time, parenting in the midst of the cultural change proved challenging, exemplified by parental worries surrounding excessive cultural assimilation of their children and a lack of knowledge surrounding U.S. norms
Implications of copper and nickel exposure to different members of the Hyalella azteca species complex
Hyalella azteca, an amphipod crustacean, is frequently used in freshwater toxicity tests. Since the mid-1980s, numerous organizations have collected and established cultures of H. azteca originating from localities across North America. However, H. azteca is actually a large cryptic species complex whose members satisfy both the biological and the phylogenetic species concepts. Recently, two publications reported that members of the H. azteca cryptic species complex have different toxicity responses to anions and an insecticide. In this study, four members of the H. azteca species complex were identified with DNA barcoding. The genetic variation among the four clades was consistent with interspecific distances between species. These lineages (clades 1, 3, 6, and 8) were cultured in identical conditions and monitored on a weekly basis to determine two life history traits: adult mortality and juvenile production. The large-bodied clades had significantly better survival and juvenile production compared to the small-bodied clade 3. Clade 6 had very low juvenile production and high mortality; therefore, was not included in this study. Unique culture protocols may be required for each clade to optimize growth, survival, and juvenile production in laboratory conditions. Genetic barcoding has identified only two clades in a survey of 17 laboratories. Therefore these two clades (1 and 8) were compared after exposure to copper and nickel 14-day toxicity tests. Clade 8 was 2.3-2.6 times more tolerant to copper exposure than clade 1 based on their LC50 and LC25. Similarly, clade 8 was more tolerant to nickel exposure than clade 1: LC50 was 1.8 times higher for the former. Nickel LBC50 and LBC25 were significantly different between clades by a factor of 2.1-2-8. Mortality (relative to copper concentrations in tissue), growth, and bioaccumulation responses were not significantly different based on overlapping confidence intervals. Although clades 1 and 8 are both large-bodied ecomorphs, these lineages had significantly different body mass (i.e., dry weight) after 14 days. The results of this study indicate that genetically characterized cultures of H. azteca should be used in toxicity tests.
Adverse Childhood Experiences and Alcohol Consumption in Midlife and Early Old-Age.
AIMS: To examine the individual and cumulative effects of adverse childhood experiences (ACEs) on alcohol consumption in midlife and early old-age, and the role of ACEs in 10-year drinking trajectories across midlife. METHODS: Data were from the Whitehall II study, a longitudinal British civil service-based cohort study (N = 7870, 69.5% male). Multinomial logistic regression was used to examine the individual and cumulative effects of ACEs on weekly alcohol consumption. Mixed-effect multilevel modelling was used to explore the relationship between ACEs and change in alcohol consumption longitudinally. RESULTS: Participants who were exposed to parental arguments/fights in childhood were 1.24 (95% CI 1.06, 1.45) times more likely to drink at hazardous levels in midlife (mean age 56 years) after controlling for covariates and other ACEs. For each additional exposure to an ACE, the risk of hazardous drinking versus moderate drinking was increased by 1.12 (95% CI 1.03, 1.21) after adjusting for sex, age, adult socio-economic status, ethnicity and marital status. No associations between ACEs and increased risk of hazardous drinking in early old-age (mean age 66 years) were found. In longitudinal analyses, ACEs did not significantly influence 10-year drinking trajectories across midlife. CONCLUSION: The effect of exposure to parental arguments on hazardous drinking persists into midlife
No Police in Schools: A Vision for Safe and Supportive Schools in CA
"No Police in Schools: A Vision for Safe and Supportive Schools in CA"Â analyzes data from the U.S. Department of Education's 2017-18 Civil Rights Data Collection (CRDC), the 2019 California Racial and Identity Profiling Act (RIPA) Stops dataset, and data from Stockton Unified School District on police in schools. The data conclusively show harmful and discriminatory policing patterns in schools. School police contribute to the criminalization of tens of thousands of California students, resulting in them being pushed out of school and into the school-to-prison pipeline. Critically, the data suggest that schools underreport the number of assigned law enforcement officers, so these problems are likely even more severe
Anion Distribution, Structural Distortion, and Symmetry-Driven Optical Band Gap Bowing in Mixed Halide Cs2SnX6 Vacancy Ordered Double Perovskites.
Mixed anion compounds in the Fm3Ě…m vacancy ordered perovskite structure were synthesized and characterized experimentally and computationally with a focus on compounds where A = Cs+. Pure anion Cs2SnX6 compounds were formed with X = Cl, Br, and I using a room temperature solution phase method. Mixed anion compounds were formed as solid solutions of Cs2SnCl6 and Cs2SnBr6 and a second series from Cs2SnBr6 and Cs2SnI6. Single phase structures formed across the entirety of both composition series with no evidence of long-range anion ordering observed by diffraction. A distortion of the cubic A2BX6 structure was identified in which the spacing of the BX6 octahedra changes to accommodate the A site cation without reduction of overall symmetry. Optical band gap values varied with anion composition between 4.89 eV in Cs2SnCl6 to 1.35 eV in Cs2SnI6 but proved highly nonlinear with changes in composition. In mixed halide compounds, it was found that lower energy optical transitions appeared that were not present in the pure halide compounds, and this was attributed to lowering of the local symmetry within the tin halide octahedra. The electronic structure was characterized by photoemission spectroscopy, and Raman spectroscopy revealed vibrational modes in the mixed halide compounds that could be assigned to particular mixed halide octahedra. This analysis was used to determine the distribution of octahedra types in mixed anion compounds, which was found to be consistent with a near-random distribution of halide anions throughout the structure, although some deviations from random halide distribution were noted in mixed iodide-bromide compounds, where the larger iodide anions preferentially adopted trans configurations
Revisiting Salvucci’s Semi-analytical Solution for Bare Soil Evaporation with New Consideration of Vapour Diffusion and Film Flow
Bare soil evaporation is controlled by a combination of capillary flow, vapour diffusion and film flow. Relevant analytical solutions mostly assume horizontal flow conditions and ignore gravitational effects. Salvucci (1997) provided a rare example of a semi-analytical solution for vertical bare soil evaporation. However, they did not explicitly represent vapour diffusion and film flow, which are likely to account for a significant proportion of total flow during vertical evaporation from soils. Vapour diffusion and film flow can be incorporated via Salvucci’s desorptivity parameter, which represents the proportionality constant relating Stage 2 cumulative evaporation to the square root of time under horizontal flow conditions. The objective of this article is to implement vapour diffusion and film flow within Salvucci’s semi-analytical solution and test its performance by comparison with isothermal numerical simulation and relevant experimental data. The following important conclusions are drawn. Analytical solutions that assume horizontal flow conditions are inadequate for understanding vertical evaporation problems because they overestimate evaporation rates and mostly predict vapour diffusion and film flow to be of negligible influence. Salvucci’s semi-analytical solution is effective at predicting the order-of-magnitude reduction in evaporation caused by gravitational effects. However, it is unable to identify the correct importance of vapour diffusion and film flow because these processes can only be represented through its desorptivity parameter
Infection and Inflammation Leading to Clozapine Toxicity and Intensive Care: A Case Series
Objective: To describe 3 cases of clozapine toxicity associated with infectious and/or inflammatory processes.
Case Summaries: 3 patients stable on clozapine therapy prior to a medical hospital admission developed clozapine toxicity. It was suspected that an acute infectious and/or inflammatory process in each patient was related to abrupt mental status changes, onset of sialorrhea, myoclonus, and/or need for ventilatory support. Investigations of altered mental status did not reveal alterative causes and presentations were not consistent with neuroleptic malignant syndrome, other acute neurologic complications, or psychiatric decompensation. All patients improved after clozapine dose reductions allowing for transfer from intensive care units. Using the Naranjo ADR Probability Scale for each case, a probable relation between clozapine toxicity and the infectious and/or inflammatory process was determined.
Discussion: Clozapine toxicity may manifest with multiple symptoms including sedation, sialorrhea, and hypotension. In addition to overdose and drug interactions; infection and/or inflammation may precipitate clozapine toxicity. This may be related to cytokine-mediated inhibition of cytochrome P450 1A2. The likelihood of toxicity via this mechanism has not been well-characterized, thus careful monitoring is required for medically ill patient receiving clozapine. Clozapine is extensively bound to the acute phase reactant, alpha-1 acid glycoprotein, which may unpredictably protect against clinical toxicity. C-reactive protein has also been investigated to relate clozapine toxicity to infection and/or inflammation.
Conclusion: Clozapine toxicity developed in 3 patients admitted to a medical setting suspected to be related to infection and/or inflammation. Clinicians should be aware of this potential adverse drug event with clozapine
Cognitive Behavioural Therapy, Core Information Document
Cognitive-behavioural therapy (CBT) holds a unique status in the field of mental health – CBT is effective for many psychological problems, is relatively brief, and is well received by individuals. A large volume of research has been published regarding CBT, including a number of well-designed studies involving people in “real world” clinical settings. Yet despite this large base of evidence, information about CBT has not been well communicated to consumers, families, and providers of health care. Consequently, CBT is not being used as extensively as the research would warrant. Many individuals (consumers, families, and professionals alike) are unaware of the effectiveness of CBT for different problems. There is additional uncertainty about the effectiveness of different formats of CBT (for example, individual, group or self-help formats), who can provide CBT, how to access their services, and other treatments with which CBT is used (for example, the use of medication and CBT together). This Core Information Document has been assembled for the benefit of individuals, families and service providers interested in a broad summary of information relating to CBT and its effectiveness
