Examination of Nitrogen to Phosphorus Ratio in Nutrient Removal from Wastewater through Chlorella vulgaris

A need for phosphorus removal is becoming increasingly evident as some wastewater treatment plants struggle to meet wastewater effluent nutrient requirements. High nutrient levels in wastewater effluents have also caused ongoing tension between the state of Oklahoma and Arkansas regarding the pollution of the Illinois River. This research seeks to establish the relationship between nitrogen to phosphorus ratio in wastewater and the level of nutrient reduction using Chlorella vulgaris. Seed cultures of Chlorella vulgaris were added into solutions with various ratios of nitrate to phosphate representative of treated domestic wastewater and the removal of nitrogen and phosphorus were measured in this study. Results showed phosphate is the limiting factor for Chlorella vulgaris. The removal of nitrate from phosphate-limited wastewater effluent increased significantly by the growth of Chlorella vulgaris when supplemented with phosphate. This suggests that algal nutrient removal might not be suitable as a tertiary treatment for all wastewater effluent. This study will enhance wastewater treatment plants’ knowledgebase about further nutrient reduction techniques, and in turn, make more informed decisions

Navigating Transparent Pork Production: Analyzing Visual Attention of The Maschhoffs Website

When it comes to food, consumers are increasingly concerned with the welfare of the livestock used to produce it. To display transparency and build trust with patrons, businesses such as The Maschhoffs, a pork production company, have created online tools to answer questions about production processes. This study implemented eye tracking and survey methodologies to attain insight regarding the visual attention of website visitors. While results revealed no discernable pattern of navigation among respondents, the findings illustrated a sector of the pork industry consumers expressed interest in was the breed-to-wean section of the farm. Researchers encourage agricultural communicators to develop messaging surrounding this specific process to continue building trust with consumer audiences as well as make recommendations for utilizing eye tracking to assess visual attention to websites

Sex Differences in Mechanisms and Outcome of Neonatal Hypoxia-Ischemia in Rodent Models: Implications for Sex-Specific Neuroprotection in Clinical Neonatal Practice

Clinical findings show that male infants with hypoxic-ischemic injury (HI) fare more poorly than matched females on cognitive outcomes. Rodent models of neonatal hypoxia-ischemia support this difference, with data showing that perinatal brain injury leads to long-term behavioral deficits primarily in male rodents and in female rodents treated with early androgens. Results support the idea that sex-specific gonadal hormones may modulate developmental response to injury and dovetail with overwhelming evidence of developmental androgen effects on typical brain morphology and behavior. However, mechanisms underlying sex differences in response to early brain injury may be more complicated. Specifically, activation of cell death pathways in response to HI may also differ by sex. In females, the preferential activation of the caspase-dependent apoptotic pathway may actually afford greater protection, potentially due to the actions of X-linked inhibitor of apoptosis (XIAP) within this pathway. This contrasts the pattern of preferential activation of the caspase-independent pathway in males. While an integrated model of sex-specific hormonal and genetic modulation of response to early injury remains to be fully elucidated, these findings suggest that infants might benefit from sex-specific neuroprotection following HI injury

Tales from the Other Side: Librarians and Vendors Get Real

Three professionals who have worked as vendors and as librarians throughout their careers discussed overlapping competencies for both roles. These were outlined as adaptive negotiation, managing and prioritizing tasks, optimizing the library/vendor partnership, coping with unique stressors, understanding how to frame your own career, clear communication and expectation setting, recognizing patterns and adapting, and empathy. The presenters encouraged listeners to move beyond understanding the relationship between librarians and vendors as adversarial or as one of simply buying and selling products. They advocated instead to think of the relationship as one of mutual respect and collaboration, where people in both roles share common goals of delivering excellent customer servic

Persuasive Effects of Metaphors Regarding Gene-Editing in Agriculture

Gene-editing provides an opportunity to address the significant challenges of population growth and climate change that impact food production. Given the important role of gene-editing in our food system, exploring opportunities to persuade public acceptance of the technology is needed. The purpose of this study was to investigate persuasive effects of metaphorical concepts regarding gene-editing in agriculture. The Elaboration Likelihood Model was used as the conceptual framework. Metaphors stand to influence public acceptance because metaphors encourage issue-relevant thinking and enhance persuasion. A quantitative, randomized, between-subjects, experimental research design was delivered via an online survey to a nationally representative sample of U.S. residents. The manipulation was four mock news articles differentiated by metaphorical concept for gene-editing in agriculture (creation versus text editor versus tool versus control). Even when controlling for confounding variables, the results indicated no significant differences between the treatments on issue-relevant thinking or willingness to share the article on social media. Future research should explore the impact of metaphorical concepts on attitude and other behavioral outcomes associated with elaboration

Group Psychological Treatment Preferences of Individuals Living With Chronic Disease: Brief Report of a Saskatchewan-Based Cross-Sectional Survey

Given that individuals with chronic diseases comorbid with psychological distress experience worse clinical outcomes than those without psychological distress, treatment of the psychological sequalae that accompanies chronic diseases is of utmost importance. Thus, the present study aimed to examine group treatment preferences among adults living with chronic disease in Saskatchewan, Canada. An online survey regarding group treatment preferences was administered to 207 participants living with chronic disease comorbid with psychological distress. The most often reported treatment scenario was virtual sessions (45%) lasting 1 h (51%) and occurring every other week (45%) in the evening (63%) for 3 to4 months (40%). Preferences included a medium group (48%), a relatively closed group nature (ie, only occasional new members; 44%), and group leadership including at least 1 professional living with chronic disease (54%). Future-oriented (81%), supportive (83%), skill-based (95%), and group discussions (78%) were desired treatment characteristics among participants. Survey results showed clear preferences on treatment content and session logistics. Slight variations exist by gender and age, but a consensus can be identified and act as a preliminary treatment plan. This study contributes to the body of literature on psychological treatment preferences for individuals living with chronic disease by outlining the preferred format and composition of groups according to those with lived experience. Group-based psychological treatment for chronic disease patients should account for these preferences to improve its acceptability and usefulness among patients

What’s Next for Tobacco Control Efforts? Health Equity Related Lessons Learned from a National Qualitative Study on Tobacco Control and Prevention

Context: Despite gains in the tobacco prevention and control movement, tobacco products remain a threat, with specific populations at greater risk. Objective: The purpose of this paper is to examine the role that leaders in the tobacco prevention and control movement have played in progress achieved to date and identify recommendations for the future using a health equity framework. The purpose of this paper is to examine the role that leading organizations in the tobacco prevention and control movement have played in progress achieved to date, identify future recommendations within the context of current public health priorities (e.g., obesity prevention), and explore potential for tobacco prevention and control using a health equity framework. Design: Qualitative key informant interviews were conducted with representatives from four key tobacco prevention and control organizations and their partners. Setting: Interviews were conducted on-site at tobacco prevention and control organization offices or by telephone. Participants: Key informant interviews (n=87) were conducted during July-December of 2017. Main outcome measures: Interviewees describe their work in providing technical assistance to leading public health and policy efforts in tobacco prevention and control. Interviews were transcribed verbatim and coded for meaning units. This analysis was conducted November 2017-January 2018. This study was determined exempt from review by the University of Nebraska Medical Center Institutional Review Board. Results: Three overarching themes emerged from our analysis: (1) maintaining tobacco prevention and control as a public health issue, (2) the importance of health equity in tobacco prevention and control work, and (3) planning for the next generation of tobacco prevention and control advocates. Certain populations remain untouched by broad public health approaches to reduce tobacco use. Conclusions: Tailored, focused, and comprehensive approaches to address health equity in tobacco prevention and control work across specific communities are needed. Adopting a health equity lens across public health priority areas (e.g., obesity, opioids, and tobacco prevention and control) could reduce prevalence among vulnerable groups for multiple conditions
