The Moderating Effect of Supervisory Social Support on the Relationship between Second Generation Latinos’ and Asians’ Assimilation Level and Work-Family Conflict

The majority of the empirical work regarding work-family conflict (WFC) has been focused on the experiences of White, middle class, Anglo-Americans. The labor force, however, is experiencing major demographic changes as increasing numbers of U.S.-born Latinos and Asians become employees. Although second generation Latinos and Asians play a major role in the U.S. economy and workplace, their experiences as employees have seldom been examined. Because they are exposed to collectivistic and individualistic values simultaneously, their assimilation levels, or identification with the U.S. culture, could be a unique predictor of a type of WFC: work-interference with family (WIF) or family interference with work (FIW). Using 103 second generation Latino and Asian employees, the present study was aimed to understand the influence of cultural variables on WFC by examining the relationship between their assimilation levels and type of WFC. It was hypothesized that the more assimilated they were, the more WIF and the less FIW they would experience. In addition, perceived supervisor support was introduced as a moderator of the relationship between assimilation levels and type of WFC. The findings of this study revealed that contrary to the hypothesis, assimilation levels were not related to WIF or FIW, nor did perceived supervisor support moderate their relationship. However, the study did provide further evidence that perceived supervisor support could reduce WIF. Given these findings, organizations should look to revamp their work-family balance initiatives and provide the necessary training to their front-line supervisors to instill a sense of supervisory support among employees

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

ISR a personas físicas residentes en el extranjero con fuente de riqueza en México

Una interrogativa en los temas del cálculo de retención de ISR es la correspondiente a los residentes en el extranjero con fuente de riqueza en México cuales son las ventajas y desventajas del impuesto sobre la renta, debido que muy poco se ha hablado del tema en particular. No sin antes, mencionar que la información aquí tratada constituye un verdadero reto para el contribuyente, que se encuentra dentro de este supuesto, ya que así como en su lugar de residencia, como aquí en México tendrá que pagar el impuesto

Virome and bacteriome characterization of children with pneumonia and asthma in Mexico City during winter seasons 2014 and 2015.

Acute asthma exacerbations and pneumonia are important causes of morbidity and mortality in children and may coexist in the same children, although symptom overlap may lead to difficulties in diagnosis. Microbial and viral diversity and differential abundance of either may play an important role in infection susceptibility and the development of acute and chronic respiratory diseases.To describe the virome and bacteriome present in the upper respiratory tract of hospitalized children with a clinical diagnosis of asthma and pneumonia during an acute exacerbation and an acute respiratory illness ARI episode respectively.During the winter seasons of 2013-2014 and 2014-2015, 134 nasopharyngeal swabs samples of children <15 years of age with ARI hospitalized at a referral hospital for respiratory diseases were selected based on clinical diagnosis of asthma or pneumonia. The virome and bacteriome were characterized using Whole Genome Sequencing (WGS) and in-house bioinformatics analysis pipeline.The Asthma group was represented mainly by RV-C, BoV-1 and RSV-B and the pneumonia group by Bacteriophage EJ-1 and TTMV. TTV was found in both groups with a similar amount of reads. About bacterial composition Moraxella catarrhalis, Propionibacterium acnes and Acinetobacter were present in asthma and Veillonella parvula and Mycoplasma pneumoniae in pneumonia. Streptococcus pneumoniae and Haemophilus influenzae were mostly found with both asthma and pneumonia.Our results show a complex viral and bacterial composition in asthma and pneumonia groups with a strong association of RV-C presence in asthmatic children. We observed Streptococcus pneumoniae and Haemophilus influenzae concurrently in both groups
