Using Our Voice: Supporting College Student Mental Health Through Radio Outreach in a Mental Health Nursing Course.

ABSTRACT: The COVID-19 pandemic affected clinical placements for nursing students throughout the United States, especially in rural areas. Public service announcements were created through a collaborative service-learning project between the school of nursing and the university radio station. Baccalaureate nursing students developed and delivered short public service announcements focused on issues of loneliness, stress, and anxiety and provided information about community resources. The alignment of this meaningful project with course learning outcomes gave students exposure to the social determinants of health as well as best practices in mental health outreach.

Reports of past alcohol and drug use following participation in a motivation enhancing intervention: implications for clinical assessment and program evaluation.

BACKGROUND: There is significant interest in the value of motivational approaches that enhance participant readiness to change, but less is known about clients' self-reports of problematic behavior when participating in such interventions. METHODS: We examined whether participants in a motivationally-based intervention for DUI offenders changed their reports of substance use at postintervention (when reporting on the same 30 days that they reported on at preintervention). Specifically, Study 1 (N = 8,387) tested whether participants in PRIME For Life (PFL) changed their reports about baseline substance levels when asked at postintervention versus at preintervention. Study 2 (N = 192) compared changes in self-reported baseline drinking between PFL and intervention as usual (IAU) participants. RESULTS: Many participants in Study 1 did not change their reports about how much they used substances during the 30-day period before baseline. Among those who did, the most common change was an increase in reported amounts of baseline drug use, and typical and peak alcohol use. This sample also showed changes in reports of their baseline pattern of high-risk-use (consistent versus occasional). At postintervention, participants who were younger, single, or endorsing more indicators of alcohol dependence were more likely to later report greater frequency of baseline drug use, and greater peak and typical number of baseline drinks. Gender, education, and race were also associated with reporting inconsistency on some behaviors. In Study 2, PFL participants showed greater increases in reports of peak alcohol use compared to IAU, but both conditions showed similar increases for drugs and typical alcohol use. CONCLUSIONS: In both research and clinical settings, a segment of participants may initially report less substance use than they do when asked later about the same baseline period. These preliminary findings suggest clinicians and researchers may find postintervention evaluations yield reports of greater baseline alcohol or drug use for some people. For some behaviors, this may occur more often in interventions that target client motivation. Future research should attempt to identify which reports - preintervention vs. postintervention - better reflect actual baseline substance use.

Short-term outcomes of a motivation-enhancing approach to DUI intervention.

OBJECTIVE: We compared a group-delivered, theory-based, motivation-enhancing program (PRIME For Life(®) - PFL, n=450) to an intervention as usual (IAU, n=72). METHOD: Individuals convicted of a substance related offense in North Carolina, typically first offense alcohol and drug-impaired driving, participated in a PFL or IAU group. We compare the interventions on program satisfaction and changes made from preintervention to postintervention, and examined the moderating effects of demographics and alcohol dependence level. RESULTS: When significant, findings varied in magnitude from small to medium effects. Participants in both interventions showed intentions to use statistically significantly less alcohol and drugs in the future compared to their previous use, and differences between the groups were not statistically significant. Otherwise, findings favored PFL. PFL exhibited greater benefit than IAU on understanding tolerance, perceived risk for addiction, problem recognition, and program satisfaction. Additionally, IAU perceived less risk for negative consequences postintervention than they had at preintervention. Moderation analyses showed that the between-condition findings occurred regardless of gender, age, education, and number of alcohol dependence indicators. Additionally, younger people and those with more dependence indicators - groups of particular concern - showed the greatest change. CONCLUSIONS: Findings suggest that a motivation-enhancing approach can be effective in producing short-term change in factors that can help facilitate and sustain behavioral change. This is consistent with previous research on the use of motivational approaches, and extends such findings to suggest promise in group-based settings and with people across demographic categories and dependence levels. Future research should focus on larger studies looking at long-term behavioral change, including recidivism.

FT-IR as an alternative method for measuring chemical properties during composting.

Chemical properties have been used as a way of following the composting process and compost maturity, however, their analysis is very time consuming as each must be separately determined. By developing a more rapid method to predict these properties, time and cost would be saved. This study investigates the use of Fourier Transform mid-Infrared Spectroscopy (FT-IR) for this purpose. FT-IR spectra and measured values of several chemical properties from a variety of compost mixtures were used to produce calibrated models using partial least-squares regression analysis which predicted the known chemical properties. These models displayed a range of accuracies that for most properties was more than sufficient to follow at least broad dynamic changes associated with maturation. The best calibrations were achieved for total C, total N, LOI, lignin, and cellulose with r(2) values within the range 56-77%. Some degree of calibration was achieved for available-P and NH(4)(+)-N, with r(2) values of between 40% and 57%. No useful calibration could be achieved for NO(3)(-) or pH.

Remediation of metal polluted mine soil with compost: co-composting versus incorporation.

Trace element contamination of post-industrial sites represents a major environmental problem and sustainable management options for remediating them are required. This study compared two strategies for immobilizing trace elements (Cu, Pb, Zn, and As) in mine spoil: (1) co-composting contaminated soil with organic wastes and (2) conventional incorporation of mature compost into contaminated soil. Sequential chemical extraction of the soil was performed to determine temporal changes in trace element fractionation and bioavailability during composting and plant growth. We show that mine spoil can be co-composted successfully and this action causes significant shifts in metal availability. However, co-composting did not lead to significant differences in metal partitioning in soil or in plant metal uptake compared with simply mixing mine spoil with mature compost. Both treatments promoted plant growth and reduced metal accumulation in plants. We conclude that co-composting provides little additional benefit for remediating trace-element-polluted soil compared with incorporation of compost.

Strobilurin fungicides induce changes in photosynthetic gas exchange that do not improve water use efficiency of plants grown under conditions of water stress.

The effects of five strobilurin (beta-methoxyacrylate) fungicides and one triazole fungicide on the physiological parameters of well-watered or water-stressed wheat (Triticum aestivum L.), barley (Hordeum vulgare L.) and soya (Glycine max Merr.) plants were compared. Water use efficiency (WUE) (the ratio of rate of transpiration, E, to net rate of photosynthesis, A(n)) of well-watered wheat plants was improved slightly by strobilurin fungicides, but was reduced in water-stressed plants, so there is limited scope for using strobilurins to improve the water status of crops grown under conditions of drought. The different strobilurin fungicides had similar effects on plant physiology but differed in persistence and potency. When applied to whole plants using a spray gun, they reduced the conductance of water through the epidermis (stomatal and cuticular transpiration), g(sw), of leaves. Concomitantly, leaves of treated plants had a lower rate of transpiration, E, a lower intercellular carbon dioxide concentration, c(i), and a lower net rate of photosynthesis, A(n), compared with leaves of control plants or plants treated with the triazole. The mechanism for the photosynthetic effects is not known, but it is hypothesised that they are caused either by strobilurin fungicides acting directly on ATP production in guard cell mitochondria or by stomata responding to strobilurin-induced changes in mesophyll photosynthesis. The latter may be important since, for leaves of soya plants, the chlorophyll fluorescence parameter F(v)/F(m) (an indication of the potential quantum efficiency of PSII photochemistry) was reduced by strobilurin fungicides. It is likely that the response of stomata to strobilurin fungicides is complex, and further research is required to elucidate the different biochemical pathways involved.
