According to the punctuated equilibrium thesis, government attention allocation alternates between long periods of stasis and dramatic spurts of disequilibrium because democratic institutions enable minority groups to obstruct change. This article presents a critical discrepancy in contemporary China, where punctuated instability is significantly more intense despite a lack of democratic institutions to empower minority obstructionism. Our empirical analysis further reveals that punctuated intensity goes even higher for Chinese regions facing fewer signs of social discontent. We attribute the intensification of punctuated dynamics to an information disadvantage arising from the lack of diverse, independent sources of information under authoritarianism. Our finding contributes to punctuated equilibrium theory by underlining the function of opposition groups not only as obstructionists but also as challengers to policy priorities. By marginalizing these challengers, authoritarian institutions confine attention to known problems, leading to serious delays in the discovery of and adjustment to emerging issues.

Environmental justice (EJ) is the concept that all people and communities, regardless of their race and socioeconomic status, are entitled to enjoy an equally clean environment and resources. Communities where residents face environmental injustice and a higher risk of being exposed to environmental hazards due to their race, ethnicity, and socioeconomic status are called EJ communities. The purpose of this manuscript is to provide an example of nurses' involvement in observation, assessment, and intervention of an EJ community using a community-based participatory research (CBPR) model.Utilizing a multistage CBPR approach along with a mixed methods design, the project was carried out in three stages. Within the three stages, we conducted a thorough observation of the community, identified possible environmental issues, and collected health data and drinking water samples. Citizens' complaints included coal ash, failed sewer system, health issues, including kidney disorders and neuropathy. Drinking water samples (n = 59) showed lead levels higher than the health limits in 10.4% of samples. We intervened based on our short-term goal, reducing citizens' exposure to lead by education, and our long-term goal, reducing disparities, and exposures. We recommend that nurses increase their knowledge about EJ communities and environmental exposures and their health effects and be advocates for EJ communities.

The objective of the present study was to elucidate the relationship between amino acid consumption and necessary profiles of Streptococcus thermophilus T1C2 to guide the design of media for high-cell-density culture. The amino acid consumption and necessary patterns of S. thermophilus T1C2 were investigated in the complete chemically defined medium. For amino acid consumption profiles throughout the growth of S. thermophilus T1C2, the most abundantly consumed amino acids were Gln and Arg, which accounted for 19 and 20% of total amino acids consumed, respectively. Asparagine, Thr, Ser, Ala, Val, Met, Leu, and Lys, consumptions of which ranged from 3 to 10% of total amino acids consumed, were the second most intensively consumed amino acids. For necessary amino acid patterns, the amount of Cys, which counted for 11% of total amino acids needed, was significantly higher than the amounts required for other amino acids in growth of S. thermophilus T1C2. The necessary amounts of Asp, Asn, Glu, Gln, Arg, Ala, Met, and Tyr ranked second, ranging from 5 to 8% of total amino acids needed. Compared with necessary amounts, the consumption of Asn, Thr, Ser, Gln, Arg, Ala, Val, Leu, Lys, His, and Phe exceeded the necessary amounts for growth of S. thermophilus T1C2 remarkably. Consumption of Gly, Met, Ile, Trp, and Pro was slightly higher than the necessary amounts. Consumption of Asp, Glu, Tyr, and Cys was lower than the necessary amounts. The overall consumption of amino acids exceeded the required amount for growth of S. thermophilus T1C2 almost 2.43 times, which implied a significant nitrogen wasting.

Objective: Globally, indoor and outdoor pollutants are leading risk factors for death and reduced quality of life. Few theories explicitly address environmental health within the nursing discipline with a focus on harmful environmental exposures. The objective here is to expand the National Institutes of Health Symptom Science Model to include the environmental health concepts of environmental endotype (causative pathway) and environmental exposure. Design: Meleis' research to theory strategy for theory refinement was used. Research workshop proceedings, environmental health nursing research expert consensus, panelist research trajectories, and review of the literature were utilized as data sources. Results: Ongoing emphasis on the physical environment as a key determinant of health and theoretical perspectives for including environmental exposures and endotypes in symptom science are presented. Definitions of these concepts, further developed, are provided. Recommendations to strengthen environmental health nursing research and practice through capacity building/infrastructure, methods/outcomes, translational/clinical research, and basic/mechanistic research are included. Conclusion: The revised model deepens theoretical support for clinical actions that include environmental modification, environmental health education, and exposure reduction. This modification will enable a middle-range theory and shared mental model to inspire the prioritization of environmental health in nursing leadership, research, practice, and education.

Environmental justice (EJ) means socially and economically disadvantaged communities and citizens are entitled to an equally clean environment and resources to enjoy. EJ communities are mostly located close to polluters such as Superfund sites, coal‐fired power plants and landfills and are more likely to be exposed to higher levels of environmental hazards than the U.S. population on average. It is often a difficult task to identify EJ communities and the environmental hazards in the communities without using specific EJ screening tools. Therefore, the goal of this manuscript is to introduce public health nurses to map‐based EJ screening tools. This will help public health nurses to identify EJ communities and take appropriate actions. Public Health Nurses can also use other relevant web sites, such as the U.S. Environmental Protection Agency (EPA), National Institute of Environmental Health Sciences (NIEHS) and Toxicology Data Network (TOXNET) as resources concerning potential health effects of pollutants. Using the provided tools in this paper, nurses should be able to identify EJ communities and be united to recognize barriers of EJ communities and become promoters for EJ advocacy in practice, leadership and education.
