Full text linkExploring Racially Informed Factors and Assessing Their Impacts on the Working Conditions and Burnout among Bicultural Asian Human Service Workers
Full text linkThe United States has undergone a significant increase in cultural diversity, with Asians being the fastest-growing immigrant group. Their population has almost doubled from 11.9 million in 2000 to 22.4 million in 2019, marking an 88% increase in less than two decades. Presently, Asians make up 6% of the total U.S. population and are estimated to grow to 46 million by 2060, representing over 10% of the U.S. population. Asians are often considered a model minority due to their higher educational and health status compared to other minority groups. However, they are still perceived as perpetual foreigners regardless of their length of stay and generational status in the country. During the pandemic, they became the target of pandemic-related racism that was supported by a political agenda. Amidst unprecedentedly heightened racism and collective trauma in the Asian community, bicultural and bilingual Asian human service workers play a critical role in providing culturally and linguistically aligned health and social services. However, these dedicated workers have not received much attention. Therefore, this research, based on the Asian Critical Race Theory, investigates how the racial positioning and racial realities of Asians in the United States relate to the working conditions of bicultural and bilingual Asian human service workers. This study uses a sequential exploratory mixed-method approach to explore the connection between racially informed factors and the working conditions and burnout of workers in the health and social service fields. The study applies the Job Demands and Job Resources Model to understand this link. The findings of this study support the need to better support a diverse and resilient workforce in the health and social service fields to achieve racial equity for an ever-growing Asian population
A Biofilm Channel Origin for Vermiform Microstructure in Carbonate Microbialites
Full text linkA three-dimensional tubular fabric known as ‘vermiform microstructure’ in Phanerozoic and Neoproterozoic carbonate microbialites has been hypothesized to represent the body fossil of nonspicular keratose demosponges. If correct, this interpretation extends the sponge body fossil record and origin of animals to ~890 Ma. However, the veracity of the keratose sponge interpretation for vermiform microstructure remains in question and the origin of the tubular fabric is enigmatic. Here we compare exceptionally well-preserved microbialite textures from the Upper Triassic to channel networks created by modern microbial biofilms. We demonstrate that anastomosing channel networks of similar size and geometries are produced by microbial biofilms in the absence of sponges, suggesting the origin for vermiform microstructure in ancient carbonates is not unique to sponges and perhaps best interpreted conservatively as likely microbial in origin. We present a taphonomic model of early biofilm lithification in seawater with anomalously high carbonate saturation necessary to preserve delicate microbial textures. This work has implications for the understanding of three-dimensional biofilm architecture that goes beyond the current micro-scale observations available from living biofilm experiments, and suggests that biofilm channel networks have an extensive fossil record
