Ep025 about writing children's book, and teaching children about history and folklore in fun and exciting ways.
No full textCharis Cotter is an award-winning children’s writer, actor and storyteller who has worked extensively in schools telling Newfoundland ghost stories and encouraging students to collect local ghost stories from their communities. In 2013 she published The Ghosts of Baccalieu, a book of traditional ghost stories by students from Tricon Elementary in Bay de Verde. Her latest storytelling presentation, The Ghosts of Grates Cove, is an hour of ghost stories from one of the most haunted places in Newfoundland, Conception Bay North. We discuss Charis’ work as an author, how she teaches children facts through games and fun, school programs, and ghost stories
Dante's Beatrice ("dolce amica") and Petrarch's Laura ("dolce nemica") : "charis" and poetry
No full textTematem artykułu jest analiza dwóch najsłynniejszych postaci kobiecych w literaturze włoskiej, Beatrycze i Laury i roli, jaką ich charis, rozumiana jako uroda, wdzięk, ale także piękno wewnętrzne, czy nawet łaska w – przypadku Beatrycze – oraz pełen sprzeczności obraz wewnętrzny Laury rzutujący na stosunek poety do niej, odegrały w twórczości Dantego i Petrarki i w pojmowaniu przez nich celów poezji. Przedmiotem zainteresowania nie są historyczne cechy osobowości Beatrycze i Laury (nie wiemy nawet, czy ta ostania istniała naprawdę), a jedynie ich wyobrażenie literackie, obecne w różnych dziełach obu twórców. W analizie o charakterze interpretacyjnym autorka artykułu odwołuje się do "Vita Nuova" i "Divina Commedia" Dantego oraz do "Secretum" i "Rerum vulgarium fragmenta" Petrarki. Auto-dekonstrukcji miłosnej iluzji młodszego poety zostaje przeciwstawiony ewolucyjny wymiar miłości Alighierego: oba te zjawiska decydująco wpłynęły na rozwój ich twórczych osobowości.The article contains an analysis of two most famous female characters in Italian literature: Beatrice and Laura and the role which their charis performed in the oeuvre of Dante and Petrarch. The author also analyses the poets’ understanding of the functions of poetry. Charis was described as beauty, grace, but also internal beauty, or even mercy – as in the case of Beatrice, and an internal image of Laura full of contradictions which affected the relation of the poet to her. The object of the research is not the historical attributes of Beatrice and Laura (we even do not know whether the latter actually existed), but their literary representations existing in different works of both authors. In the interpretative analysis the author refers to "Vita Nuova" and "Divina Commedia" by Dante and "Secretum" and "Rerum vulgarium fragmenta" by Petrarch. The auto-destructive amorous illusion of the younger poet has
been juxtaposed with the evolutionary dimension of affection by Alighieri: both phenomena decisively influenced the development of their artistic work
Implementation of a class-wide intervention to teach behavioral expectations in Head Start
No full textChildren and teachers were recruited from two Head Start programs in a Midwestern city to participate in this study focused on behavioral expectations. Using a multiple probe design across four classrooms, the impact of scripted stories, role play, and prompts was examined. Teachers were trained on how to implement effective strategies to teach behavioral expectations to young children. Although a functional relation was not established, teachers implemented the evidence-based strategies with high fidelity which resulted in adherence to behavioral expectations for two child participants.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2017-12-01The student, Charis Price, accepted the attached license on 2015-11-19 at 16:13.The student, Charis Price, submitted this Dissertation for approval on 2015-11-19 at 16:36.This Dissertation was approved for publication on 2015-11-30 at 11:13.DSpace SAF Submission Ingestion Package generated from Vireo submission #8812 on 2016-03-02 at 14:06:00Made available in DSpace on 2016-03-02T20:23:34Z (GMT).

Combination of Pretreatment with White Rot Fungi and Modification of Primary and Secondary Cell Walls Improves Saccharification
No full textPlant cell walls have protective and structural functions conferring resistance to degradation. The lignin and hemicellulose network surrounding the cellulose microfibrils is insoluble unless subjected to harsh treatments. As lignin, pectin and xylan are effective barriers to cellulose extraction and hydrolysis, reducing their presence in cell walls improves saccharification. Microorganisms that can depolymerise lignin are of extreme interest to the biofuel industry. White rot fungi can be effective in pretreatment of lignocellulosic biomass prior to saccharification. Here, we show the cumulative effects of pretreating biomass with two white rot fungi, Phanerochaete chrysosporium and Trametes cingulata, on tobacco lines with reduced lignin or xylan, caused by suppression of the CINNAMOYL-CoA REDUCTASE, CINNAMATE-4-HYDROXYLASE, TOBACCO PEROXIDASE 60 or UDP-GLUCURONATE DECARBOXYLASE and on Arabidopsis thaliana with reduced de-esterified homogalacturonan content, obtained by overexpressing a pectin methyl esterase inhibitor or constitutively expressing the Aspergillus nigerPOLYGALACTURONASE II gene. Tests were extended to fresh material from an Arabidopsis mutant for a cell wall peroxidase. We demonstrate that fungal pretreatment is a reliable method of improving cellulose accessibility in biofuel feedstocks, fresh material and cell wall residues from different plants. These results contribute to the understanding of the consequences of primary and secondary cell wall perturbations on lignocellulosic biomass accessibility to white rot fungi and on saccharification yield. A comparison of the effects of P. chrysosporium and T. cingulata on tobacco saccharification also highlights the limitation of current knowledge in this research field and the necessity to systematically test culture conditions to avoid generalisations. © 2014 The Author(s)

Atmospheric Monitoring and Precise Spectroscopy of the HR 8799 Planets with SCExAO/CHARIS
No full textThe atmospheres of gas giant planets are thought to be inhomogeneous due to weather and patchy clouds. We present two full nights of coronagraphic observations of the HR 8799 planets using the CHARIS integral field spectrograph behind the SCExAO adaptive optics system on the Subaru Telescope to search for spectrophomometric variability. We did not detect significant variability signals, but placed the lowest variability upper limits for HR 8799c and d. Based on injection-recovery tests, we expected to have a 50% chance to detect signals down to 10% H-band photometric variability for HR 8799c and down to 30% H-band variability for HR 8799d. We also investigated spectral variability and expected a 50% chance to recover 20% variability in the H/K flux ratio for HR 8799c. We combined all the data from the two nights to obtain some of the most precise spectra obtained for HR 8799c, d, and e. Using a grid of cloudy radiative-convective-thermochemical equilibrium models, we found all three planets prefer supersolar metallicity with effective temperatures of ∼1100 K. However, our high signal-to-noise spectra show that HR 8799d has a distinct spectrum from HR 8799c, possibly preferring more vertically extended and uniform clouds and indicating that the planets are not identical. © 2022.

Japan's delayed antinuclear power mobilization after 3.11
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Political Science, 2013.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections."September 2013." Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 99-112).The meltdown of Fukushima Daiichi's nuclear plant was one of three disasters that rocked Japan on 11 March 2011, a day often referred to as "3.11." This nuclear accident led to increased attention to and disapproval of nuclear power among the Japanese public. However, despite widespread antinuclear sentiment, the public did not mobilize into sustained mass protests until June 2012. Using historical and contemporary comparisons, this thesis shows that Japan's 15- month delay in antinuclear mobilization was unusual. Both the 1979 Three Mile Island and the 1986 Chernobyl accidents had been quickly followed by mobilized protests. Moreover, the 3.11 Fukushima meltdown prompted mass protests in Germany almost immediately. Given these patterns, one would expect to have seen the Japanese mobilize earlier. The question that drives this thesis is: What led to Japan's 15-month delay in antinuclear power mobilization? Using social movement theory, I test to see whether low levels of grievance, limited availability of resources, or the lack of effective mobilizing structure and strategy help to explain this delay. Of the three explanations, I find the mobilization structure and strategy explanation to be best supported. Due to a history of overlooking antinuclear power issues in Japanese civil society, the early post-3.11 movement lacked longstanding true believers and activists, the two types of participants most effective at mobilizing. Furthermore, the use of social media platforms to organize the early protests may have contributed to why sustained protests were delayed. The empirical findings from this thesis allow us to examine more closely the devastation resulting from 3.11's nuclear meltdown and assess the strengths and weaknesses in Japanese civil society after the disaster. On a theoretical level, these findings may encourage us to question the relevance of grievance to mobilization, refine how resource availability is measured, and ask if the growing use of social media and other online tools should change the way we study social movement mobilization.by Lin Ern Charis Teo.S.M

OTEC Resource Potential Mapping: A spatial assessment, including "State of the Art" practicable criteria by using Geo-Information Systems (GIS)
No full textIn the present global scenario of a fossil fuel based economy, excessive use of non- renewable resources, such as petroleum, coal and natural gas has resulted in global warming, extreme weather events, and biodiversity loss. Therefore, the need for social, environmental and economic change is still dominant around the world and many places including the Netherlands, are proposing different alternatives to mitigate the increasing anthropogenic impact.Our Oceans with thermal energy basins covering more than 70% of our planet’s surface are noticeably the largest solar collector. Ocean Thermal Energy Conversion (OTEC) technology provides the means of harvesting this vast potential to offer a steady baseline power generation for coastal cities and regions where most of the World’s population is currently living. Nonetheless, since the nature of OTEC resources depends significantly on location-based indicators, an explicit focus has been put on this study towards the collection and examination of spatial information.Nevertheless, cold water availability in 1 km depth, constraints the total amount of electricity that could be extracted by OTEC operations. For this reason, an advanced analysis below is performed which redefines the magnitude of the resources for the development of a realistic OTEC deployment scenario which can still cover the entire electricity demand of the world.In total, the Offshore and Onshore OTEC power produce can reach up to 4.4 TW with a deep seawater flow rate of wcw=175 m/yr without causing any thermal disruptions in the ocean. Therefore, countries such as Indonesia, Papua New Guinea, Dominica, Mozambique, U.S., Indonesia, etc that have a great abundance of OTEC resources, could even exchange this power produce through a symbiotic relationship to uplift their economy andmake a step closer towards the forthcoming renewable energy transition.Industrial Ecolog
Implementation of Explicit and Implicit Runge-Kutta methods to reduce the computational cost of pollutant transport modeling
No full textAdditional thesis report - Heimovaara et al. (2015) have developed a solute transport model (STM) so as to paint a dire portrait of the leachate generation and transport in the Braambergen landfill (located in the western portion of the Netherlands) with the ultimate goal of quantifying the chemical composition of the landfill's overall emissions. In fact, the model simulates the Chloride (Cl-) concentration in the outflowing from the landfill leachate and the mass of Cl- that remains in the landfill by using an ordinary differential equation (ODE) that describes dualporosity, mobile-immobile solute transport phenomena. This environmental model, developed in MATLAB, simulates these state variables by solving the aforementioned ODE by means of the well-known ode45 solver in MATLAB. In spite of that, the computational expense of the ode45 solver does not seem to be identical (~20-30 seconds of calculations). As is widely known, various ODE solvers usually require different computing times. Namely, the selection of the method for solving such insightful equations most often affects the time efficiency of ODE-based models. In the light of these considerations, this paper exploits the robustness of several explicit and implicit Runge-Kutta methods to solve the STM's ODE in an effort to make this model more cost-effective. By virtue of the results, the fourth order explicit Runge-Kutta method along with the fourth and sixth order implicit Runge-Kutta methods have successfully managed to drastically reduce the computational cost of the STM (~4-9 seconds of calculations).Civil Engineering and GeosciencesGeoscience & EngineeringGeo-Engineerin
