A Histopathological Review of Immune Response in Largemouth Bass to Parasitic Infections of Soft Tissues
Get PDFThe immune response can serve as a key indicator of a fish’s overall health and the effect stressors have on the health of the fish. Anthropogenic factors can stress a fish’s immune system and inhibit immune responses. This study investigated the response of eosinophilic cells and macrophage aggregates to parasites in the livers, spleens, and gonads of Largemouth Bass, Micropterus salmoides. Largemouth Bass were sampled from three bodies of water in the Chattahoochee Valley of varying levels of urbanization. Histopathology of the aforementioned organs was conducted to observe both the parasite density and immune response. Eosinophilic cells were shown to be the most robust indicator of immune response based on parasite density. Bass from more urbanized areas were shown to have significantly lower immune response and significantly higher parasite density. The ovaries had the strongest immune response of all organs observed, and the livers showed the weakest response

Grassroots Mental Health Groups’ Use of Advocacy Strategies in Social Media Messaging
No full text© The Author(s) 2020. Mental health concerns are a public health crisis. Stigma is the primary reason why individuals do not disclose or seek treatment. Stigma is constructed communicatively, and destigmatization efforts—such as advocacy messaging—are also communicative. I employ a case study approach to describe how two mental health groups use advocacy strategies in their social media messaging to help audience members mitigate mental health concerns and challenge stigma. I found content creators use a variety of advocacy strategies in their messaging, including awareness-raising, support of policy initiatives, and the promotion of diversity and inclusivity. Although not the primary goal of these groups’ messaging, advocacy strategies were important to content creators and audience members, and 80% of audience members interviewed engaged in advocacy work for the organizations. I provide a nuanced view of mental health communication advocacy strategies, make recommendations for health communication professionals, and demonstrate the need for future studies
The Digital Divide: Addressing Artificial Intelligence in Communication Education
No full text© AEJMC 2020. Artificial intelligence (AI) has gained both momentum and importance within society over the past several years. This article provides an opening for further discussion to the broader social and digital media research community and those interested in answering important questions related to these areas by leveraging a focused, productive approach. In supporting future educational endeavors within the communication classroom, and specifically to this topic, we propose five important considerations that will move the conversation forward. The considerations within this article are meant to engage scholars in intellectual conversation and to provide an initial foundation for the direction of communication education. They are not meant to be an exhaustive list, but rather initiate discussions within education and research addressing implications emerging technologies have had on our field and what could be incorporated into the media and communication curriculum to prepare educators and students alike
Carbon limitation in hypereutrophic, periphytic algal wastewater treatment systems

Global eutrophication degrades water quality in freshwater ecosystems and limits the availability of freshwater for human consumption. While current wastewater treatment facilities (WWTF) remove pathogens and pollutants, many US WWTF continue to discharge nutrients that contribute to eutrophication. Traditional nutrient removal technologies can effectively reduce eutrophication risk, but can have unintended negative consequences on human and environmental health. Alternatives, such as algae-based treatment systems, improve the sustainability of the nutrient recovery process by producing biomass that can be converted to biofuel. However, research is needed to increase the productivity of algal treatment systems to improve their economic viability. Because algae in wastewater treatment systems are grown in wastewater rich in nutrients, the algae could become limited by dissolved inorganic carbon. This hypothesis was tested in 1.2 m long recirculating floways (n = 8 for each treatment/control) by quantifying algal dry mass and wastewater nutrient concentrations in 3 independent experiments: (1) carbon dioxide gas infused vs air infused control; (2) hydrochloric acid acidified vs neutralized solution control vs no chemical addition control; and (3) sodium bicarbonate addition vs no chemical control. Results showed increases in algal biomass after 18 days in wastewater augmented with dissolved inorganic carbon (carbon dioxide or sodium bicarbonate). In contrast, maintaining wastewater at near neutral pH with hydrochloric acid reduced algal productivity relative to controls. Nutrient reductions generally paralleled algal biomass increases except in the bicarbonate addition experiment. These findings provide evidence for the importance of carbon limitation in algal wastewater treatment floways. These results could help explain why carbon dioxide infusions stimulate algae in treatment systems. Furthermore, these results suggest that algae in nutrient enriched, sun-exposed streams (e.g., agricultural ditches or urbanized streams) may become carbon limited during peak periods of productivity. These findings could have important implications for ecosystems undergoing eutrophication as atmospheric carbon dioxide concentrations continue to rise
