Constituent Loads and Trends in the Upper Illinois River Watershed and Upper White River Basin

Water chemistry can greatly influence the quality of surface waters and affect the ability for streams and rivers to meet their designated use(s). In Arkansas, many streams and rivers were placed on the 2008 303(d) list of impaired water bodies due to excess levels of nutrients, chlorides, sulfates, and sediments (ADEQ, 2008). These constituents continue to be listed as the potential cause for water‐quality impairments through the most recent draft 303(d) list (ADEQ, 2014). The Arkansas Non‐Point Source (NPS) Management Program wants to reduce poll‐ utant loading from the landscape and improve water quality, where funding for projects is targeted to priority watersheds throughout the State

Constituent Load Estimation in the Lower Ouachita-Smackover Watershed

Water quality was monitored at 21 sites in the Lower Ouachita‐Smackover Watershed from 2013 November through 2014 September. The U.S. Geological Survey maintains discharge monitoring stations at two of these sites, Moro Creek (USGS 07362500) and Smackover Creek (USGS 07362100), which were sampled during base flow and storm event conditions, whereas the other sites were only sampled during baseflow. The Arkansas Water Resources Center (AWRC) estimated constituent loads for nitrate‐N (NO₃‐–N), total nitrogen (TN), soluble reactive phosphorus (SRP), total phosphorus (TP) and total suspended solids (TSS) using the U.S. Geological Survey LOADEST software. LOADEST creates regression models between constituent concentrations and discharge, as well as time. The resulting models were applied to daily discharge throughout calendar years 2013 and 2014 to estimate loads. Annual and monthly loads and flow volumes for each site are summarized in this report

Examining the curricular approach in student affairs as a tool for critical praxis

This qualitative content analysis examines the integration of theoretical frameworks and critical praxis in the curricular approach within student affairs. Data from three departmental curricula at a single institution were analyzed to explore the elements of curriculum design that reflect critical praxis and how theoretical models and frameworks are implemented. The research questions guiding this study focused on identifying the impact of theoretical frameworks on curriculum design and the role of critical praxis for student affairs practitioners. Despite the lack of explicit guidance on theory selection and integration in curriculum design spaces and the limited attention given to theory application within the curricular approach in higher education literature, this study underscores that the selection of an inherently critical theoretical framework has a significant influence on staff engagement in critical praxis. The findings underscore the importance of grounding curriculum in a critical framework that addresses power dynamics across learning goals and outcomes, advocating for a move towards collective action. The profession of student affairs has increasingly emphasized justice-oriented practice and challenging the status quo. However, there is a need for practitioners to bridge the gap between individual-level student development and the larger sociocultural contexts in which they operate. The study suggests that to answer this call, theories that engage criticality and foster collective action and reflection must be utilized in curriculum design. The study also highlights the role of student affairs organizations in shaping practitioners' ability to engage in critical praxis. It identifies the tension between the espoused values of the field and individual practitioners' enactment of those values. While professional associations and graduate preparation programs emphasize social justice and inclusion as competency areas, there is a danger of perceiving expertise in critical work as a static goal, hindering ongoing critical reflection. The findings emphasize the need for practitioners to continuously reflect on their practice and engage with theoretical frameworks to inform curriculum development and learning goals. Based on the study's findings, three implications for practice are presented. First, theoretical frameworks must move towards collective action to align with the field's goals, moving beyond the sole focus on individual student development. Second, scholars and practitioners should collaborate to produce research on critical praxis in student affairs, with practitioners uniquely positioned to contribute insights from their day-to-day experiences. Third, practitioners need to deeply engage with theoretical frameworks to design curriculum and inform learning goals and strategies, recognizing the transformative power of critical theories on individuals, institutions, and policies. The study concludes by emphasizing the need for future research to explore the execution of curricula and assess whether learning goals and outcomes are met. It calls for a focus on practitioners' role in shaping student experiences and the complexities they face in navigating student needs, institutional policies, and external pressures while promoting critical practices. Additionally, the study highlights the necessity of developing assessment practices grounded in reflexivity and centered on equity, challenging the neoliberal tendencies in the field. Ultimately, this research aims to inspire conversations and advancements in enacting critical praxis in conjunction with the curricular approach within student affairs, for the benefit of current and future students, as well as practitioners in the field

016— Quality of College Students’ Close Peer Relationships

This study compares the quality of different types of college students’ relationships: same-sex (SS) friendships, other-sex (OS) friendships, and romantic relationships. Previous research by Hand and Furman (2009) indicated that adolescents perceived their OS friendships as less supportive than both their SS friendships and romantic relationships. Adolescents also perceived their OS friendships as having less conflict than their romantic relationships. The current study attempts to replicate these findings with college students, who tend to have more time and opportunity to develop close OS friendships. In addition, we examine the power dynamic in these relationships, as well as several factors of each type of relationship, including length of the current relationship and previous experience with each type of relationship

DOES HAND SPEED RELATE TO CLUB HEAD SPEED OR BALL SPEED DURING A GOLF SWING?

Many golf swing analyses use club or ball speed to indicate performance, although these are difficult to obtain using motion capture. This study examined the relationship between hand speed and club head and ball speeds to examine if hand can indicate performance and if different capturing frequencies affect these relationships. A 10-camera Vicon system recorded golfers performing eight golf swings (500 Hz n=11, 100 Hz n=15). A TrackMan system recorded club head and ball speed. The resultant hand speed was calculated at peak velocity, the lowest position of the hands, and at ball impact. Hand speed at ball impact and club head speed had the strongest relationship (r=0.501, p\u3c0.001), though most correlations were r\u3c0.400. Higher capturing frequency had better relationships with the performance outcomes, and the ball impact was the best time point for analysis

Method for in-solution, high-throughput T1 relaxometry using fluorescent nanodiamonds

Fluorescent nanodiamonds (FNDs) have been exploited as sensitive quantum probes for nanoscale chemical and biological sensing applications, with the majority of demonstrations to date relying on the detection of single FNDs. This places significant limits on the measurement time, throughput and statistical significance of a measured result as there is usually marked inhomogeneity within FND samples. Here we have developed a measurement platform that can report the T1 spin relaxation time from a large ensemble of FNDs in solution. We first describe a refined sensing protocol for this modality and then use it to identify the optimal FND size for the detection of paramagnetic targets. Our approach is simple to set up, robust and can be used for rapid material characterisation or a variety of in-situ quantum sensing applications.Comment: 8 pages, 3 figure

Decreasing physical and verbal aggression in a brain injured nursing home resident

Following a traumatic brain injury, patients often suffer a series of psychological and psychiatric sequalae. This study presents the case of Mr. K, a 52-year-old brain-injured nursing home resident who exhibited problematic physical aggression and verbal abuse toward staff and residents. His problem behaviors were intertwined with an ethical issue involving a heterosexual relationship with another resident who also was brain injured. Following a functional assessment of antecedents and consequences, a differential reinforcement of other behavior (DRO) schedule was implemented. Specifically, the resident was rewarded with short-term and long-term reinforcers following periods of time during which behaviors other than the target behavior were emitted. Although the behavior plan was successful, it resulted in a more noticeable decrease in physically aggressive behaviors than verbally abusive behaviors. Implications include increasing awareness of use of behavior plans in nursing homes and of ethical and behavioral issues associated with sexuality among nursing home residents
