    The Megaphone of the Soul: Resistance of Fraudulent Technological Idolization by Recognizing the Power of Human Choice in Media Ecology

    Humans naturally communicate, but choose to use tools. They use them to make sense of things, even to their own detriment and the detriment of others. These tools often receive the attention, instead of the human interaction. Aristotle\u27s notion of humans as social animals has been carried into media ecology scholarship by Arendt, Burke, Ellul, Mumford, Postman, and Ricoeur. Social media scholarship has often focused on the tool and how it affects humanity. However, a phenomenological approach is necessary, as humans communicate with or without these tools. This approach will follow multiple steps. The first is through an understanding of the historical lens of civic discourse from antiquity to contemporary society. The second step is to examine why Aristotle\u27s concept of ethos still matters in social media. The third step warns how social media could be shaped into a knack environment and lead to a synthetic ethos. The fourth step analyzes how interpersonal communication interacts with social media, as well as how a noble friendship can be established in social media. The fifth step exposes how humanity is unfortunately using technology to revise modernism in a postmodern age. The sixth step details how humans can reconcile social media-in-itself with social media-for-itself. This multi-step approach seeks to understand how social media fit in humanity, and also how humans fit in social media. These steps puts a focus on humans having choice and free will, and thus, responsibility. The approach in this document is more concerned with understanding the medium and then understanding how choice affects human action and direction

    Field Evaluations of Herbicides on Vegetable, Small Fruit, and Ornamental Crops, 2000, 2001, & 2002

    Field evaluations of herbicides provide the chemical industry, governmental agencies, such as IR-4, and the Arkansas Agricultural Experiment Station with an evaluation of herbicide performance on small fruit, vegetable, and ornamental crops grown under Arkansas conditions. This report provides a means for disseminating information to interested private and public service weed scientists

    Transit times and electrical discharge in a steady-state gas activation system

    Get PDF
    This study deals with the problem of transporting a gas from the core of the Ames Laboratory Research Reactor to the ion source of an electromagnetic isotope separator in a steady-state fashion. The parameters on which this flow depends are ascertained so that the flow may be predictably controlled by a computer. The transit time through the activation line is calculated and confirmed experimentally for nitrogen and xenon. The initiation of an electrical discharge in the low pressure gas by a 60 kv potential is studied as a function of the gas and the gradient length

    Inclusionary Housing Programs: Local Governments Respond to California\u27s Housing Crisis

    Get PDF
    As anti-growth sentiment increases across the country, two laudable goals—affordable housing and environmental protection—are coming into conflict. This tension is most evident in California. Nine of the ten least affordable communities in the country are in California. California also has one of the most complicated and expensive environmental regulatory processes for development. This results in builders being unable to produce housing to keep up with demand, and an increase in the cost of those units that are available. “Smart Growth” is often proffered as the answer to this dilemma: by promoting more compact development, mixed-use and mixed-income neighborhoods, and creating jobs near housing and transportation, housing production will be available to meet the demand at affordable costs. While these principles may serve as a valuable planning guide, they are not a panacea. In this respect, local governments have used inclusionary housing programs as one tool to respond to this escalation of housing costs and probably will continue to do so

    Distance of Interference of Red Rice (Orya sativa) in Rice (O. sativa)

    Three rice cultivars were grown to determine the distance at which red rice affects growth and grain yield. Red rice reduced grain yield of Lemont when rice plants grew within 71 and 53 cm of red rice in 1986 and 1988, respectively. Grain yield of Newbonnet was reduced when grown within 53 cm of red rice in both years. Grain yield of Tebonnet was reduced when grown within 53 and 36 cm of red rice in 1986 and 1988, respectively. Grain yield reduction in influenced areas averaged 35, 26 and 21% for Lemont, Newbonnet, and Tebonnet, respectively. As the distance increased at 10-cm increments from the red rice row, Lemont, Newbonnet, and Teboment grain yields increased 49 to 85, 32 to 40, and 24 to 33 g/m2, respectively. Rice straw dry weight was reduced when Lemont and Tebonnet were grown within71 and 36 cm of red rice in 1986 and 1988, respectively. Straw dry weight of Newbonnet was reduced when grown within 36 cm of red rice in both years. As the distance increased at 10-cm increments from the red rice row, Lemont, Newbonnet and Tebonnet straw biomass increased 22 to 46, 10 to 18, and 12 to 20 g/m2,respectively. Rice panicles/ m2 were reduced when Lemont, Newbonnet, and Tebonnet were grown within 36, 18, and 18 cm of red rice, respectively. Rice grains/panicle were reduced when rice was grown within 71, 71, and 36 cm of red rice for Lemont, Newbonnet, and Tebonnet, respectively

    Reporter bacteriophage T7NLC utilizes a novel NanoLuc::CBM fusion for the ultrasensitive detection of Escherichia coli in water.

    Rapid detection of bacteria responsible for foodborne diseases is a growing necessity for public health. Reporter bacteriophages (phages) are robust biorecognition elements uniquely suited for the rapid and sensitive detection of bacterial species. The advantages of phages include their host specificity, ability to distinguish viable and non-viable cells, low cost, and ease of genetic engineering. Upon infection with reporter phages, target bacteria express reporter enzymes encoded within the phage genome. In this study, the T7 coliphage was genetically engineered to express the newly developed luceriferase, NanoLuc (NLuc), as an indicator of bacterial contamination. While several genetic approaches were employed to optimize reporter enzyme expression, the novel achievement of this work was the successful fusion of the NanoLuc reporter to a carbohydrate binding module (CBM) with specificity to crystalline cellulose. This novel chimeric reporter (nluc::cbm) bestows the specific and irreversible immobilization of NanoLuc onto a low-cost, widely available crystalline cellulosic substrate. We have shown the possibility of detecting the immobilized fusion protein in a filter plate which resulted from a single CFU of E. coli. We then demonstrated that microcrystalline cellulose can be used to concentrate the fusion reporter from 100 mL water samples allowing a limit of detection of \u3c10 CFU mL-1 E. coli in 3 hours. Therefore, we conclude that our phage-based detection assay displays significant aptitude as a proof-of-concept drinking water diagnostic assay for the low-cost, rapid and sensitive detection of E. coli. Additional improvements in the capture efficiency of the phage-based fusion reporter should allow a limit of detection of \u3c10 CFU per 100 mL
