HOMELESSNESS IN SOUTHERN CALIFORNIA: A LOOK TOWARD PREVENTION

Despite living in the richest country in the world, many individuals and families across the United States face the harsh reality of homelessness. A social phenomenon, homelessness has affected hundreds of thousands of people every year. The impact of homelessness has been detrimental across the whole country, including Southern California. This exploratory study raised two questions: (1) What are contributing factors to homelessness in Southern California? (2) How can homelessness in South California be prevented? Taking a qualitative approach, this study interviewed 15 participants, 10 social workers and 5 people living in/or having experienced homelessness (N = 15). Thematic analysis yielded four themes: 1) many factors lead to homelessness, 2) people experiencing homelessness do use social services, 3) people experiencing homelessness face structural and personal barriers, and 4) addressing homeless requires a broad range of programs. These findings have significant implications for theory, research, social work practice, and social work education in the post-COVID-19 era

Cyto-genotoxicity and oxidative stress in common carp (Cyprinus carpio) exposed to a mixture of ibuprofen and diclofenac

Thirty million people worldwide consume each day nonsteroidal anti-inflammatory drugs (NSAIDs), a heterogeneous group of pharmaceuticals used for its analgesic, antipyretic, and anti- inflammatory properties. Recent studies report high NSAID concentrations in wastewater treat- ment plant effluents, in surface, ground, and drinking water, and in sediments. NSAIDs are also known to induce toxicity on aquatic organisms. However, toxicity in natural ecosystems is not usu- ally the result of exposure to a single substance but to a mixture of toxic agents, yet only a few studies have evaluated the toxicity of mixtures. The aim of this study was to evaluate the toxicity induced by diclofenac (DCF), ibuprofen (IBP), and their mixture on a species of commercial inter- est, the common carp Cyprinus carpio. The median lethal concentration of IBP and DCF was determined, and oxidative stress was evaluated using the following biomarkers: lipid peroxidation and activity of the antioxidant enzymes superoxide dismutase, catalase and glutathione peroxi- dase. Cyto-genotoxicity was evaluated by micronucleus test, comet assay, and the specific activity of caspase-3. Results show that DCF, IBP, and a mixture of these pharmaceuticals induced free radical production, oxidative stress and cyto-genotoxicity in tissues of C. carpio. However, a greater effect was elicited by the mixture than by either pharmaceutical alone in some biomarkers evaluated, particularly in gill.Secretaria de Investigacion y Estudios Avanzados de la UAEM (Project 3722/ 2014CID)

Use of Plectranthus amboinicus in Feeding Fattening Pigs

[EN] This research was developed at the Hacienda "Los Hermanos" belonging to the company Super Mac, located in Balao canton, Guayas province, coastal region of Ecuador, the purpose of this study was to evaluate the effect of the inclusion of ground dehydrated P. amboinicus in the feed of fattening pigs on their productive parameters and antibacsterial response. Four treatments were distributed, each one with 20 animals, regardless of sex for a total of 80 pigs, starting at 49 days of age and ending the experiment at 105 days, considering each pig as an experimental unit. A Completely Randomized Design (CRD) was used, with the following treatments: Treatment 1, control (T1), to which a commercial diet was administered, T2, T3, T4 to which 0.25, 0.50 and 0.75% of the dehydrated P. amboinicus was added to the commercial diet, respectively. For data analysis, the statistical program Statgraphics Centurion XV.I ® was used, applying a one factor Analysis (ANOVA) and to establish the differences between the means obtained, the procedure of the multiple comparison of Bonferroni was used with a 95% level of confidence, the variables evaluated were: Live weight gain and accumulated feed consumption in kg, feed conversion, mortality in percentage, total microbial flora and total coliforms in CFU. The results showed that, for the variables of productive parameters, there is no statistically significant difference, although there is a difference for the variables of total coliforms and total microbial flora when compared with T1, especially at the end of the experiment. As a conclusion there is an effect at the level of the antibacterial response, showing a positive correlation, the higher the percentage of dehydrated P. amboinicus included the greater efficacy in the control of CFUs. No mortality was found during this experiment.Sanchez-Quinche, A.; Vega Tinoco, MM.; Pimbosa Ortiz, ED.; Cordovilla Loaiza, JD.; Jordán Romero, MM.; Pérez Baena, I. (2021).

Guardar/romper el silencio sobre la interrupción voluntaria del embarazo : narrativas de mujeres mexicanas

Esta investigación narrativo feminista aborda la tensión entre guardar o romper el silencio en 14 mujeres mexicanas habitantes de la Ciudad de México y de otros estados, que interrumpieron sus embarazos en el primer trimestre. Las razones para guardar silencio estaban relacionadas con la sanción social sobre el aborto o por la actividad sexual previa al matrimonio, por posibles afectaciones en sus proyectos de vida y para proteger sus decisiones; las motivaciones para hablar de esta experiencia estuvieron vinculadas con la necesidad de obtener servicios seguros y de contar con apoyo emocional, en algunos casos tuvieron un fin político y de sororidad, encaminado a disminuir el estigma y apoyar a otras mujeres. Se observó en algunos casos la ruptura del círculo vicioso entre el silencio, el estigma y la creencia de que se trata de una experiencia poco frecuente, lo que contribuye a aminorar la penalización social del aborto.This feminist narrative research addresses the tension between keeping or breaking silence in 14 women, from Mexico City and other Mexican entities, who interrupted their pregnancies in the first trimester. The reasons for remaining silent related to the social sanction on abortion or on sexual activity prior to marriage; to possible effects on their life projects and to the aim of protecting their decisions; the motivations to talk about this experience, were linked to the need to obtain safe services and to have emotional support. In some cases, breaking the silence had a political and sorority purpose, aimed at reducing stigma and supporting other women. In some cases, the breaking of the vicious circle between silence, stigma and the belief that it is a rare experience was observed, which helps to reduce the social penalization of abortion

Imaging the Kirkendall effect in pyrite (FeS2) thin films: cross-sectional microstructure and chemical features

This investigation provides novel data on the structure and chemical composition of pyrite thin films and new hints concerning their formation mechanism. From TEM-HAADF data, it has been found that the films are composed of two different layers: one is very compact and the other one is quite porous with many voids separating a few groups of grains. This porous layer is always in direct contact with the substrate, and its thickness is quite similar to that of the original Fe film. The average size of pyrite grains is equal in both layers, what suggests that the same process is responsible for their formation. Concentration profiles of sulfur, iron and some impurities (mainly sodium and oxygen from the glass substrate) through both layers are given in this work, and thus chemical inhomogeneities of the films are proved by the obtained stoichiometric ratios (S/Fe). Moreover, Na from sodalime glass substrates mainly accumulates at the pyrite grain boundaries and barely dopes them. The obtained results support the hypothesis that the iron sulfuration process essentially induces the diffusion of iron atoms, what leads to the porous layer formation as a manifestation of the Kirkendall Effect. Therefore, it seems that the same mechanisms that operate in the synthesis of surface hollow structures at the nanoscale are also active in the formation of pyrite thin films ranging from several tens to hundreds of nanometersMembers of MIRE Group acknowledge the financial support of the Spanish MICINN under project RTI2018-099794-B-I00.
