Family functioning but not social capital is associated with better mental health in adolescents affected by violence and displacement by armed conflict in Colombia

Background: The effect of the Colombian armed conflict on the mental health of adolescents is still poorly understood. Aims: Given social interventions are most likely to inform policy, we tested whether two potential intervention targets, family functioning and social capital, were associated with mental health in Colombian adolescents, and whether this was moderated by experience of violence and displacement. Methods: We examined the cross-sectional association between family functioning, cognitive social capital, structural social capital and 12-month prevalence of Composite International Diagnostic Interview (CIDI) diagnosed psychiatric disorder, using data on 12 to 17-year-old adolescents (N = 1,754) from the 2015 National Mental Health Survey of Colombia, a nationally representative epidemiological study. We tested whether associations survived cumulative adjustment for demographic confounders, experience of non-specific violence and harm and displacement by armed conflict. Results: Neither structural nor cognitive social capital were associated with better mental health. Better family functioning was associated with reduced risk of poor mental health in an unadjusted analysis (OR 0.90 [0.85–0.96]), and after cumulative adjustments for demographic confounders (OR 0.91 [0.86–0.97]), non-specific violence and harm (OR 0.91 [0.86–0.97]) and social capital variables (OR 0.91 [0.85–0.97]). In the final model, each additional point on the family APGAR scale was associated with a 9% reduced odds of any CIDI diagnosed disorder in the last 12 months. Conclusions: Better family functioning was associated with better mental health outcomes for all adolescents. This effect remained present in those affected by the armed conflict even after accounting for potential confounders

Preliminary Measurements of Be-10/Be-7 Ratio in Rainwater for Atmospheric Transport Analysis

The meteoric cosmogenic beryllium has been used as an essential geophysical tracer in the analysis of atmospheric flows and erosion soils since 1960. The first measurements Be-7 and Be-10 concentrations in rainwater from Mexico, have been carried out by using gamma decay spectroscopy and AMS techniques, respectively for each isotope. With this it was possible to report a preliminar value for the Be-10/Be-7 isotopic ratio in such environmental samples. The present work described preliminary results related to rainwater collected at mountain and metropolitan areas. Results are compared with predictions and previous measurements for both radioisotopes, observing a very sensible behavior particularly for the case of Be-7 activities

Total and Monomethyl Mercury in Fog Water from the Central California Coast

[1] Total mercury (HgT) and monomethyl mercury (MMHg) concentrations in fog collected from 4 locations in and around Monterey Bay, California during June-August of 2011 were 10.7 ± 6.8 and 3.4 ± 3.8 ng L−1respectively. In contrast, mean HgT and MMHg concentrations in rain water from March-June, 2011 were 1.8 ± 0.9 and 0.1 ± 0.04 ng L−1 respectively. Using estimates of fog water deposition from 6 sites in the region using a standard fog water collector (SFC), depositions of HgT and MMHg via fog were found to range from 42–4600 and 14–1500 ng m−2 y−1, which accounted for 7–42% of HgT and 61–99% of MMHg in total atmospheric deposition (fog, rain, and dry deposition), estimated for the coastal area. These initial measurements suggest that fog precipitation may constitute an important but previously overlooked input of MMHg to coastal environments. Preliminary comparisons of these data with associated chemical, meteorological and oceanic data suggest that biotically formed MMHg from coastal upwelling may contribute to the MMHg in fog water

Estudio Preliminar Sobre La Decoloración Del Residual Líquido De La Producción De Papel Mediante Ozonización

Preliminarily, the relationship between Color Reduction (%RC), Total Suspended Solids concentration (SST), and as independent variable, the time of Ozone Oxidation Process, was evaluated with reference values of DQO of the black liquor adjusting its concentration from SST to 300 and 50mg/dm3. A batch reactor of 12,60dm3, an effective height of 3,2dm and an ozone generating device from SEFILTRA company (air flow of 2dm3/min, c(O3) of 9,50mg/dm3 with a O3(g) production 19mg/min) was used. The polynomic correlation was determined from 192 data sets with satisfactory adjustment level (R=0,92; p <0,001). Although, preliminarily, the DQO reduction (%RDQO) was not included in the polynomial relationship, it can be concluded that: a) The %RC and %RDQO is reduced when color and DQO increases from the ozonized sample at same time intervals; this reduction is greater when the SST levels of the ozonized sample increases. b) The %RC and %RDQO decrease when the SST level of the ozonized sample increases. c) Depending on the initial color, of the DQO and of the SST level of the sample, values from 10 to 53 %Rc were obtained after 10 min, and of 66 to 94 %Rc after 60 min

Trasformaciones eclesiales. Propuestas del papa Francisco para una iglesia en pastoral

Jorge Mario Bergoglio llegó al Vaticano con un sentido de autocrítica y con el propósito de hacer cambios sustanciales. Lo que propone el papa es que la Iglesia católica deje de ser autorreferencial, salga de sí misma y vaya hacia las periferias, no solo geográficas sino también las existenciales. Sin embargo, todo cambio enfrenta inercias, más cuando se busca una trasformación desde dentro de una institución milenaria. En este libro, académicos de cinco universidades mexicanas analizan la figura, el discurso y las acciones de Francisco en sus primeros años en la sede papal, así como las críticas internas y externas a su labor, lo que permite dimensionar el alcance de la tarea que se ha impuesto el sumo pontífice

Evaluation of chemical resistance inducers in maradol papaya against Phytophthora nicotianae var. parasitica

Objective: To test the efficiency of four chemical resistance inducers in Maradol papaya, to reduce the infections of Phytophthora nicotianae var. parasitica in rainfed crops. Design / methodology / approach: Three doses of each of four resistance inducers were tested in 60-day-old papaya plants in a greenhouse, in a completely randomized design, with four replications and 10 plants as experimental plot. The inoculations with mycelium discs were made three days after the application of the treatments with the inducers, including negative and positive control treatments to evaluate the efficiency applying the Abbott formula. Results: The four chemical inducers (sodium silicate (SS), potassium silicate (SP), potassium phosphite (FP) and acibenzolar-s-methyl (ASM)) presented statistically differences to the negative control (P <0.0001 **). The inductors SS at 1%, SP 1%, FP 0.35% and ASM 0.1 mM showed greater effectiveness (81.2, 75.9, 74.7 and 74.0%, respectively). Study limitations/implications: The effective concentrations retained were tested in a single application, and their durability is not known, so it should be expanded on this point, but it can be an alternative for repeated use after transplantation. Findings/conclusions: the optimal concentrations of PS, SS, PF and ASM which respond against Phytopthora, which must to reduce damage in rainfed planting.Objective: To test the efficiency of four chemical resistance inducers on Maradol papaya to reduce Phytopthora nicotianae var. parasitica infections in rainfed crops at Chontalpa, Tabasco, Mexico.

Predictors of Compliance with COVID-19 Guidelines Across Countries: The role of social norms, moral values, trust, stress, and demographic factors

Despite the devastating impacts of the COVID-19 pandemic, it provided the opportunity to investigate factors associated with compliance with public health measures that could inform responses to future pandemics. We analysed cross-country data (k = 121, N = 15,740) collected one year into the COVID-19 pandemic to investigate factors related to compliance with COVID-19 guidelines. These factors include social norms, moral values, trust, stress, and demographic factors. We found that social norms to follow preventive measures were positively correlated with compliance with local prevention guidelines. Compliance was also predicted by concern about the moral value of harm and care, trust in government and the scientific community, stress, and demographic factors. Finally, we discuss country-level differences in the associations between predictors and compliance. Overall, results indicate that the harm/care dimension of moral foundations and trust are critical to the development of programs and policies aimed at increasing compliance with measures to reduce the spread of disease
