Evaluating the Effectiveness of Economic Incentives to Enhance Riparian Buffer Adoption and Environmental Benefits for Water Quality and Carbon Sequestration in Maryland
(2024-10) Newburn, David; Lichtenberg, Erik; Kim, Youngho; Wietelman, Derek; Wang, Haoluan
This report assesses the effectiveness of economic incentives in encouraging Maryland farmers to adopt riparian buffers for improved water quality and carbon sequestration. Using a statewide landowner survey and integrated environmental-economic modeling, the study evaluates program design features such as payment type, contract length, and targeting. Results show that upfront payments increase participation, targeted bonuses improve cost-effectiveness, and carbon offset payments offer limited added benefit. Policy recommendations focus on enhancing program efficiency through strategic incentive design.

The Role of Parental Responsibility in Relation to the Familial Link of Anxiety
(2025) Wang, Hannahlise; Chronis-Tuscano, Andrea; Bui, Hong Nhu Thi
Anxiety has a strong familial link in which parent anxiety increases the risk for child anxiety. Behavioral inhibition (BI) is also a risk factor for the development of anxiety, and parent factors (i.e., overprotection, overcontrol) exacerbate this risk. Studies examining the link between parent and child anxiety have mainly focused on genetics and childrearing styles. Few studies have explored the role of coparenting, and none have specifically studied parental responsibility, which refers to parents’ degree of involvement in caregiving activities. Limited studies have also incorporated both parents’ anxiety and child anxiety within the same model to capture a comprehensive family approach. This study utilized hierarchical regression to investigate the association between parent and child anxiety severity and how parental responsibility may play a role in the association. Post-hoc analyses were also conducted to further explore the relationships discovered between main variables (parent anxiety severity, child anxiety severity, parental responsibility). This cross-sectional secondary data analysis utilized baseline data from a randomized controlled trial comparing two treatments for young children high in BI, the Turtle Program and Cool Little Kids. The full sample consisted of 151 children and their primary parents and coparents. The final study sample consisted of 81 families with data on parental responsibility. Coparent anxiety was directly linked with child anxiety, whereas primary parent anxiety was not, suggesting the importance of considering both parents’ anxiety when examining the association between parent and child anxiety. Greater involvement in caregiving activities by both parents was also associated with lower child anxiety severity, suggesting that having more balance between parents in the amount of time they spend in caregiving activities may be an important factor for child anxiety severity. Based on the study, the role of coparent anxiety and balance in parental responsibility may be important to consider when assessing and treating families with children elevated in BI. Future studies should consider incorporating additional family, coparenting, and parenting factors to gain a more comprehensive understanding of how balance in parental responsibility may play a role in the link between parent and child anxiety.

Selective cleavage and measurement of mucin with proteases: treatment and diagnostic.
(2025) Michels, Cadence; Wu, Louisa
Airway epithelial mucus is a key component of pathogen clearance and immune response as mucin complexes entrap irritants within the mucus hydrogel and expel them through coughing. For mucus to successfully function, it requires a proper ratio of mucins MUC5AC and MUC5B within the hydrogel complex to form the ideal viscosity. The underlying pathology of asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis include significant overexpression of MUC5AC, causing highly viscous airway mucus and interfering with disease clearance and respiration. We explore the application of designed proteases to selectively cleave MUC5AC and restore the healthy mucin ratio in MUC5AC upregulated samples. Furthermore, we are investigating a protease-substrate complex that triggers the release of a fluorescent molecule as cleavage occurs as a possible diagnostic tool to measure concentrations of MUC5AC across samples.
