Suitability Assessment of Ohio's Soils for Soil-Bases Wastewater Treatment
Author Institution: Food, Agricultural, and Biological Engineering and Natural Resources, The Ohio State UniversityEach of Ohio's 467 soil series was assessed to determine the depth of the soil to bedrock, the depth to a limiting soil condition, the depth to seasonal saturation, and the soil permeability. Each soil series was placed into one of three categories; suited for traditional leach fields or mound systems, suited for mound systems only, or not suited for soil-based treatment. In a mound system, a layer of sand is placed on top of the natural soil to augment its treatment capacity. Statewide only 6.4% of the land area is suited for soil absorption systems using traditional leach lines. This amounts to 1,680,020 acres of land. Soil series suited for mound systems are present in 25.4% of Ohio's land area accounting for 6,667,579 acres of land
Curriculum Wars and Cold War Politics: The Struggle for Academic Freedom in Higher Education
During the early 1960s, in the formative years of Florida\u27s newest university, the University of South Florida located in Tampa, the Florida Investigative Committee in true McCarthy-era style, set up its Star Chamber interviews with students and others at local motels near the University. The purpose of these interviews was to ferret out information about university administrators and instructors which would point to either their innocence or their guilt in terms of communist party membership, homosexuality, or the teaching of atheism. After an exhaustive process which left the intellectual community on Florida\u27s West Coast shaken and dismayed at what it collectively believed was a misguided mission and waste of taxpayer dollars, academic communities in other university towns throughout Florida responded with outrage over the intrusion of politicians and perceived anti-intellectuals into the business of higher education. Some had already run the investigative committee\u27s gauntlet, others likely feared they would follow. In what could have resulted in the sudden demise of the infant university, its leaders and faculty emerged from the experience, not as victors, but rather as survivors of a bitter battle over academic freedom. This study serves to fill the growing body of research on the McCarthy era and its influence on education. It will cover as a case study the entire struggle of the university over the issue of academic freedom and the attempts of well-meaning citizens to control what is taught and in what way it is taught at the most sacred of investigative places—the university
Built environment assessment: Multidisciplinary perspectives.
Context:As obesity has become increasingly widespread, scientists seek better ways to assess and modify built and social environments to positively impact health. The applicable methods and concepts draw on multiple disciplines and require collaboration and cross-learning. This paper describes the results of an expert team׳s analysis of how key disciplinary perspectives contribute to environmental context-based assessment related to obesity, identifies gaps, and suggests opportunities to encourage effective advances in this arena. Evidence acquisition:A team of experts representing diverse disciplines convened in 2013 to discuss the contributions of their respective disciplines to assessing built environments relevant to obesity prevention. The disciplines include urban planning, public health nutrition, exercise science, physical activity research, public health and epidemiology, behavioral and social sciences, and economics. Each expert identified key concepts and measures from their discipline, and applications to built environment assessment and action. A selective review of published literature and internet-based information was conducted in 2013 and 2014. Evidence synthesis:The key points that are highlighted in this article were identified in 2014-2015 through discussion, debate and consensus-building among the team of experts. Results focus on the various disciplines׳ perspectives and tools, recommendations, progress and gaps. Conclusions:There has been significant progress in collaboration across key disciplines that contribute to studies of built environments and obesity, but important gaps remain. Using lessons from interprofessional education and team science, along with appreciation of and attention to other disciplines׳ contributions, can promote more effective cross-disciplinary collaboration in obesity prevention
Young adults understanding and readiness to engage with palliative care: extending the reach of palliative care through a public health approach: a qualitative study
Abstract Background Moving palliative care from a solely clinical focus to a more population based and community orientated approach is the hallmark of a much advocated public health approach to palliative care. Young adults are a vital cohort of the public, yet their understanding of palliative care has not been investigated. This study aimed to explore young adults’ understanding of palliative care and identify factors that influence their engagement. Methods A purposive sample of young adults (n = 24) aged 18–29 years were recruited from one UK University. Semi-structured interviews were undertaken face to face or via telephone or Skype between November 2017 and February 2018. Thematic analysis using a framework approach and underpinned by a socioecological perspective was used to analyse the interviews. Results Three thematic categories were identified relating to intrapersonal and interpersonal influences, cultural and social influences and organisational and public policy influences. Palliative care was understood as supportive comfort care, delivered in the absence of cure, associated with the end of life and specifically focused on death and dying. Negative attitudes related to the context of care, which represented a static and hopeless situation. Whilst some reported positive attitudes, potential engagement was seen to be governed by a lack of knowledge and protective cultural norms. In terms of demonstrating readiness to engage with palliative care, participants requested clear information and suggested a normalising of palliative care through the education system. Conclusion Young adults in this study were ready to find out more about palliative care and identified social media as a platform upon which to engage this population. However, their perception of a society that views palliative care as a subject for those directly affected, creates a barrier to engagement. This study identified the ingredients of a public health message and mediums for disseminating the message. However, findings also suggest that a cultural shift is required to recognise the potential of engaging young adults in health issues that cross the life span, empowering them not only as individuals but as vital members of community and society
PinR mediates the generation of reversible population diversity in Streptococcus zooepidemicus
Opportunistic pathogens must adapt to and survive in a wide range of complex ecosystems. Streptococcus zooepidemicus is an opportunistic pathogen of horses and many other animals, including humans. The assembly of different surface architecture phenotypes from one genotype is likely to be crucial to the successful exploitation of such an opportunistic lifestyle. Construction of a series of mutants revealed that a serine recombinase, PinR, inverts 114 bp of the promoter of SZO_08560, which is bordered by GTAGACTTTA and TAAAGTCTAC inverted repeats. Inversion acts as a switch, controlling the transcription of this sortase-processed protein, which may enhance the attachment of S. zooepidemicus to equine trachea. The genome of a recently sequenced strain of S. zooepidemicus, 2329 (Sz2329), was found to contain a disruptive internal inversion of 7 kb of the FimIV pilus locus, which is bordered by TAGAAA and TTTCTA inverted repeats. This strain lacks pinR and this inversion may have become irreversible following the loss of this recombinase. Active inversion of FimIV was detected in three strains of S. zooepidemicus, 1770 (Sz1770), B260863 (SzB260863) and H050840501 (SzH050840501), all of which encoded pinR. A deletion mutant of Sz1770 that lacked pinR was no longer capable of inverting its internal region of FimIV. The data highlight redundancy in the PinR sequence recognition motif around a short TAGA consensus and suggest that PinR can reversibly influence the wider surface architecture of S. zooepidemicus, providing this organism with a bet-hedging solution to survival in fluctuating environments

Barriers and enablers to Caregivers Responsive feeding Behaviour (CRiB): A mixed method systematic review protocol
Background: Childhood overweight and obesity is a major public health issue. Responsive feeding has been identified as having a protective effect against child overweight and obesity, and is associated with healthy weight gain during infancy. Responsive feeding occurs when the caregiver recognises and responds in a timely and developmentally appropriate manner to infant hunger and satiety cues. Despite its benefits, responsive feeding is not ubiquitous. To better support caregivers to engage in responsive feeding behaviours, it is necessary to first systematically identify the barriers and enablers associated with this behaviour. This mixed-methods systematic review therefore aims to synthesise evidence on barriers and enablers to responsive feeding using the COM-B model of behavioural change.
Methods: 7 electronic databases will be searched (Maternal and Infant Care, CINAHL, Cochrane, PubMed, Medline, PsycINFO, EMBASE). Studies examining factors associated with parental responsive and non-responsive feeding of infants and children (<2 years) will be included. Papers collecting primary data, or analysing primary data through secondary analysis will be included. All titles, abstracts and full texts will be screened by two reviewers. Quantitative and qualitative data from all eligible papers will be independently extracted by at least two reviewers using pre-determined standardised data extraction forms. Two reviewers will independently assess the methodological quality of the studies using the Mixed Methods Appraisal Tool (MMAT). This review will be reported according to the Preferred Reporting Items for Systematic reviews and Meta Analyses (PRISMA).
Ethics and dissemination: Ethical approval is not required for this review as no primary data will be collected, and no identifying personal information will be present. The review will be disseminated in a peer reviewed journal
Exploring Identity: What We Do as Qualitative Researchers
Although there has been much discussion about distinctions between quantitative and qualitative research, our purpose here is not to revive those conversations, but instead to attempt to explore and articulate our identities as researchers who practice in the qualitative tradition. Using autoethnography as our methodology, we as six researchers from various social science disciplines and at various career stages engaged in focused introspection by responding individually to two questions: who am I as a qualitative researcher; and how did I come to that understanding? This reflection led to discussions of those elements and experiences that have shaped the way we see ourselves in the context of our research. The question of “identity” evolved into a discussion about “what we do.” During our data analysis, six themes emerged, representing our group’s responses: (a) building epistemology, (b) making/doing good research, (c) as an art or craft, (d) why does qualitative research need legitimating? (e) qualitative research as a social bridge, and (f) stewards of people’s lived experience. We conclude by reflecting on the value of building a community of practice among qualitative researchers
Quid Pro Flow
How do you get into flow? We trained in flow chemistry during postdoctoral research and are now applying it in new areas: materials chemistry, crystallization, and supramolecular synthesis. Typically, when researchers think of "flow", they are considering predominantly liquid-based organic synthesis; application to other disciplines comes with its own challenges. In this Perspective, we highlight why we use and champion flow technologies in our fields, summarize some of the questions we encounter when discussing entry into flow research, and suggest steps to make the transition into the field, emphasizing that communication and collaboration between disciplines is key
