Los trastornos musculo esqueléticos son un factor que contribuye al desarrollo de lumbalgia, produciendo ciertas limitaciones en la vida cotidiana. El teletrabajo ha conllevado a la aparición de lesiones musculo esqueléticas como el síndrome del túnel carpiano, la enfermedad de De Quervain y la lumbociática. El objetivo del presente estudio es evaluar los trastornos musculo esqueléticos en abogados peruanos que realizan teletrabajo. Se realizó un estudio descriptivo y transversal, utilizando el Cuestionario Nórdico de Kuorinka. La población estuvo constituida por 156 abogados, seleccionados mediante un muestreo no probabilístico por conveniencia. Se aplicó estadística descriptiva, utilizando frecuencia y porcentaje. De los 156 abogados peruanos estudiados, se obtuvo que el 46.2% pertenecía al grupo etario de 30 a 39 años; el 62.2% eran mujeres; el 80.8% residía en la capital, Lima; el 81.4% contaba con licenciatura; el 54.5% realizaba teletrabajo durante un intervalo de 7 a 8 horas al día; y el 62.2% trabajaba de 5 a 7 días a la semana. Los abogados presentaron molestias de una duración menor a 1 hora en el cuello (57.1%) y en los hombros (51.3%). Además, la duración de las molestias fue del 40.4% en el cuello, 60.3% en los hombros, 51.3% en el codo o antebrazo y 59% en la muñeca o mano. Por lo tanto, se concluye que el teletrabajo, aunque novedoso, requiere de capacitaciones para prevenir trastornos musculo esqueléticos.

In birds, sexual selection on plumage may promote sexual dichromatism and male ornamentation. However, even in drab species without obvious sexual dichromatism, plumage may still be used for mate choice. A previous study found weak but significant sexual size dimorphism in North American Black Terns (Chlidonias niger surinamensis), but no assortative mating based on morphology. However, the relevance of plumage variation to mate choice in this species is yet untested. Here, using reflectance spectrometry and avian visual modeling, we revealed that Black Tern males and females exhibited a subtle but significant difference in brightness (males darker) in a midwestern USA population. Importantly, the achromatic contrast between the sexes was perceptible during mate choice. Moreover, there was evidence of disassortative mating for plumage color as measured by hue and saturation, but not brightness. There was no relationship between plumage color or brightness and body mass. This finding suggests that visual signals unrelated to body condition may be relevant to Black Tern mate choice. The pattern of disassortative mating was unexpected, and potential benefits of choosing a mate dissimilar from oneself are discussed. This study highlights the importance of considering the avian visual system when studying plumage variation elusive to human observers.

Caffeine is a natural compound that inhibits the major cellular signaling regulator TOR, leading to widespread effects including growth inhibition. S. cerevisiae yeast can adapt to tolerate high concentrations of caffeine in coffee and cacao fermentations and in experimental systems. While many factors affecting caffeine tolerance and TOR signaling have been identified, further characterization of their interactions and regulation remain to be studied. We used experimental evolution of S. cerevisiae to study the genetic contributions to caffeine tolerance in yeast, through a collaboration between high school students evolving yeast populations coupled with further research exploration in university labs. We identified multiple evolved yeast populations with mutations in PDR1 and PDR5, which contribute to multidrug resistance, and showed that gain-of-function mutations in multidrug resistance family transcription factors PDR1, PDR3, and YRR1 differentially contribute to caffeine tolerance. We also identified loss-of-function mutations in TOR effectors SIT4, SKY1, and TIP41, and show that these mutations contribute to caffeine tolerance. These findings support the importance of both the multidrug resistance family and TOR signaling in caffeine tolerance, and can inform future exploration of networks affected by caffeine and other TOR inhibitors in model systems and industrial applications.

The primary objective of this study is to examine the extent of financial integration between Latin American and US financial markets, particularly in light of recent efforts to foster integration through trade agreements. Spanning from 1 January 1990 to 31 December 2019, the sample focuses on major market indices and key sectors. Financial integration is quantified using a DCC multivariate GARCH model, incorporating a smooth transition model, structural breaks, and regression-based approaches. Results indicate increased comovement with the US for main market indices in Argentina, Chile, Colombia, Mexico, and Peru, while Brazil shows a decrease. Similar trends are observed in sectoral analyses. This study also reveals heightened correlation post-trade agreements. Structural break analysis highlights significant shifts in dynamic correlations for countries with US free trade agreements. These findings support the argument of increased financial integration, bearing significance for portfolio diversification and international policy formulation.

Building on the concept of transformative learning and exploring the role of reflection in graduate professional education, this article uses student and educator reflections from the graduate course on reading practices to narrate four stories of learning. These stories, structured based on the “4Ls” model of reflection, describe what was Learned and Liked in the course and what both the student and the educator Lacked and Longed for as a result of the course. An argument is made in support of not limiting Library and Information Science reading education to techniques and skills for providing reading suggestions (i.e., readers’ advisory) but for enriching this education with reflective exercises, a theoretical foundation of reading behaviors, and challenging intellectual and affective engagements that will contribute to a well-rounded practitioner education that facilitates the reading experience.

ABSTRACT Older adults play a vital role as elders in faith communities, yet little is known about their needs, perceptions, support, and belonging within faith-based communities. The present qualitative study explored older adults’ lived experiences within Christian and Jewish faith communities via structured interviews. Participants reported vital aspects of aging within their faith communities, including Significance of Age, Experiences of Support, Connection and Belonging, Understanding of Isolation/Exclusion, and Invitations for Transition. Key themes are discussed in detail, along with potential future directions to better support older adults within religious and spiritual communities. Implications for education and practice are considered.

Abstract Household financial management has several criteria of performance that makes it possible to evaluate the relative effectiveness of an individual in the particular job. To date, there has been little analysis of the myriad tasks and behaviors that are included in the role of a household financial manager, or what we term household chief financial officer (HCFO). Using techniques from industrial psychology and personnel selection, namely job analysis, the current article provides definitions of categories of critical tasks and behaviors of the HCFO job using two studies. The results of the studies identified the frequency of engagement of financial tasks across the two samples, and the importance of tasks associated with financial success.
