Crisis Migration Adverse Childhood Events: A New Category of Youth Adversity for Crisis Migrant Children and Adolescents.

The present article proposes an extension of the concept of adverse childhood experiences (ACEs) to apply to crisis migration - where youth and families are fleeing armed conflicts, natural disasters, community violence, government repression, and other large-scale emergencies. We propose that adverse events occurring prior to, during, and following migration can be classified as crisis-migration-related ACEs, and that the developmental logic underlying ACEs can be extended to the new class of crisis-migration-related ACEs. Specifically, greater numbers, severity, and chronicity of crisis-migration-related ACEs would be expected to predict greater impairments in mental and physical health, poorer interpersonal relationships, and less job stability later on. We propose a research agenda centered around definitional clarity, rigorous measurement development, prospective longitudinal studies to establish predictive validity, and collaborations among researchers, practitioners, and policymakers.

Production of pine sawdust biochar supporting phosphate-solubilizing bacteria as an alternative bioinoculant in Allium cepa L., culture.

We produced and characterised biochar made from Caribbean pine sawdust as raw material. The biochar (BC500) was used as biocompatible support to co-inoculate phosphate solubilizing bacteria (PSB) (BC500/PSB) on Allium cepa L., plants at a greenhouse scale for four months. The three biomaterials study included proximate analysis, elemental analysis, aromaticity analysis, scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), adsorption studies at different pH and PSB stability as a function of time. The results indicated that BC500 is suitable as organic support or solid matrix to maintain the viability of PSB able to solubilise P from phosphate rock (PR). The biofertilizer (BC500/PSB) allows increasing germination, seedling growth, nutrient assimilation, and growth of Allium cepa L., because PSB immobilised on BC500 promoted nutrient mobilisation, particularly P, during cultivation of Allium cepa L., at pots scale. The two treatments to evaluate the biofertilizer (BC500/PSB) showed the highest concentrations of total P with 1.25 ± 0.13 and 1.38 ± 0.14 mg bulb-1 in A. cepa L. This work presents the benefits of a new product based on bacteria naturally associated with onion and an organic material (BC500) serving as a bacterial carrier that increases the adsorption area of highly reactive nutrients, reducing their leaching or precipitation with other nutrients and fixation to the solid matrix of the soil.

Cultural stress, daily well-being, and internalizing and externalizing symptoms among Hispanic college students.

The present study was designed to examine the extent to which, in a sample of 873 Hispanic college students, daily levels of, and variability in, well-being would mediate the predictive effects of culturally related stressors (discrimination, negative context of reception, and bicultural stress) on internalizing and externalizing symptoms 11 days later. A 12-day daily diary design was utilized, where reports of cultural stressors were gathered on Day 1, daily well-being reports were gathered on Days 2-11, and outcomes were measured on Day 12 (with controls for Day 1 levels of these same outcomes). Structural equation modeling results indicated that daily means of, and variability in, well-being significantly mediated the predictive effect of Day 1 ethnic/racial discrimination, negative context of reception, and bicultural stress on Day 12 symptoms of anxiety and depression. No effects emerged for externalizing symptoms. When we decomposed the latent well-being variability construct into its component indicators (self-esteem, life satisfaction, psychological well-being/self-acceptance, and eudaimonic well-being), daily variability in life satisfaction and self-acceptance appeared to be primarily responsible for the mediated predictive effects we observed. These results are discussed in terms of implications for further research, for counseling practice, and for the development of more inclusive university practices and policies.

Non-domestic wastewater treatment with fungal/bacterial consortium followed by Chlorella sp., and thermal conversion of the generated sludge.

Liquid waste from biological stains is considered non-domestic wastewater difficult to treat, generating high environmental impact. Therefore, the objective of this work was to carry out secondary and tertiary treatment of these effluents at a pilot scale, using a fungal/bacterial consortium followed by Chorella sp., for 15 days. In addition, to obtain an adsorbent material for Malachite Green dye removal, sludge generated in the plant and pine bark co-pyrolysis was performed. For microalgae isolation and selection of the Chlorophyceae class, Chlorococcales order, and Chorella sp. genus Winogradsky columns were employed. After 15 days of pilot plant treatment, removal percentages of 91 ± 2%, 90 ± 4% and 17 ± 2% were obtained for Colour Units, Chemical Oxygen Demand and Nitrates, respectively. Two types of class II biochar (BC500 and BC700) and one of class III (BC300) were produced. The highest value for Fixed carbon (FC) was obtained at 300 °C (27.3 ± 3%), decreasing as the temperature increased by 25.9 ± 5% and 24.8 ± 2%, for BC500 and BC700, respectively. Biochar yield was 62.1 ± 3%, 46.3 ± 4% and 31.6 ± 3% for BC300, BC500 and BC700, respectively. Finally, BC500 and BC700 biochar efficiently adsorbed Malachite Green obtaining qe values of 0.290 ± 0.032, 0.281 ± 0.015, 0.186 ± 0.009 and 0.191 ± 0.012 mg g-1 at pH values of 4.0 and 8.0 ± 0.2, respectively. Pseudo-second order model demonstrated a chemical adsorption took place, which was influenced by pH.

The family crisis migration stress framework: A framework to understand the mental health effects of crisis migration on children and families caused by disasters.

Crisis migration refers to displacement of large numbers of individuals and families from their home countries due to wars, dictatorial governments, and other critical hazards (e.g., hurricanes). Although crisis migration can adversely influence direct and indirect effects on the mental health of adults and their children collectively as families, there is a deficiency in theory that addresses family level processes in this crisis migration context. We propose the Family Crisis Migration Stress Framework, which consolidates what is known about the multiple factors affecting mental health outcomes of crisis migrants into one cohesive model. In our article, we synthesize relevant theories and models of disaster, migration, and family resilience in order to create a framework in which to organize the complex processes that occur within families as a result of migration and that affect the mental health of children. We include examples from various national settings to illustrate the tenets of our framework. Future policy and intervention for crisis migrant should focus on the family as a unit, instead of parents and children as individual entities.
