A Climate Responsive Radiant Green Roof System for Indoor Cooling Purposes
No full textGreen roofs are a promising type of green infrastructure. The author is interested in exploring the energy saving potential of green roofs and their ability to lower heat stress on the indoor environment. A green roof’s cooling potential depends on the substrate depth, climatic conditions, vegetation types, and water availability. In Southern California, heat waves and drought conditions pose challenges for the feasibility of green roof implementation, thus making some of their environmental benefits less effective. In order to address such challenges, the author created an environmentally responsive microcontroller called Sentient Comfort. Sentient Comfort(SC) is an IoT-based project designed to influence indoor temperatures on a radiant-evaporative green roof. Based on the heat flux relationship between a green roof’s substrate and the built environment, the Sentient Comfort prototype was coupled with a radiant ceiling system to best distribute heat throughout both environments in real-time. The radiant system operated autonomously to couple/decouple the indoor space with/from a green roof as thermal energy sequestered within the substrate was distributed to maintain longer durations of indoor thermal comfort. The Sentient Comfort prototype was integrated into an Ad-Hoc test cell –located at California Polytechnic University of Pomona’s Lyle’s Center for Regenerative Studies. The radiant-evaporative test cell was compared to three other test cells: with an insulated traditional roof, a non-insulated green roof, and an insulated green roof. Environmental sensors were placed throughout the test cells and collected real-time data. All test cells with exception to the traditional roof operated with supplemental irrigation. The green roof test cells were designed to dissipate interior heat via moisture in the soil (conduction), moisture in the air (evapotranspiration), and green roof runoff. In an effort to limit water consumption, the green roof runoff was recaptured and re-introduced to the irrigation retention container. The research investigated the energy saving potential of active green roofs in arid conditions as optimized water usage served as a vector for heat transfer between the indoor and the outdoor environment. The wi-fi enabled microcontroller enabled monitoring and manual actuation of the SC prototype via smartphone using the Blynk app over an eight-week period. Data was analyzed to determine the optimal durations of irrigation and performance of the system. The integration of nighttime ventilation and an increased intensity of supplemental irrigation resulted in the SC prototype reducing temperature swings and maintaining thermal comfort longer than the other test cells

Building An Earnest and Amicable Argument Culture in the Secondary Classroom
No full textHow do we build collaborative, positive argument cultures in secondary classrooms? In this article, the author walks through two methods for doing this. First, the author describes the use of organized sentence templates for making collaborative argument more accessible to students. Second, the author lays out a method for facilitating whole-class, argumentative discussions: pop-up debate. Classroom examples are provided to illustrate the concepts
DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire
No full textThe majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire
Crime and God\u27s Judgment in Shakespeare
No full textDivine retribution, Robert Reed argues, is a principal driving force in Shakespeare\u27s English history plays and three of his major tragedies. Reed finds evidence of the playwright\u27s growing ingenuity and maturing skill in his treatment of the crime of political homicide, its impact on events, and God\u27s judgment on the criminal.
Reed\u27s analysis focuses upon Tudor concepts that he shows were familiar to all Elizabethans—the biblical principle of inherited guilt, the doctrine that God is the fountainhead of retribution, with man merely His instrument, and the view that conscience serves a fundamentally divine function—and he urges us to look at Shakespeare within the context of his time, avoiding the too-frequent tendency of twentieth-century critics to force a modern world view on the plays.
Heaven\u27s power of vengeance provides an essential unifying theme to the plays of the two historical tetralogies, Julius Caesar, Hamlet, and Macbeth. By analyzing these plays in the light of values held by Shakespeare\u27s contemporaries, Reed has made a substantial contribution toward clarifying our understanding of the plays and of Elizabethan England.
Robert Rentoul Reed Jr., is the author of Bedlam on the Jacobean Stage, The Occult on the Tudor and Stuart Stage, and Richard II: From Mask to Prophet. He is professor of English, emeritus, at Pennsylvania State University.https://uknowledge.uky.edu/upk_english_language_and_literature_british_isles/1051/thumbnail.jp
Sun corridor 2035
No full textabstract: Arizona is one of the nation’s most urban states, and now it includes one of 20 “megapolitan” areas in the U.S. People have predicted for 50 years that Phoenix and Tucson would grow together into a giant desert conglomerate. That possibility has been seen as exciting, intriguing, and distressing. While a solid city along Interstate 10 is unlikely given the diverse land ownership in central and southern Arizona, the two metro economies are already merging.
Megapolitan: Arizona’s Sun Corridor, one of the first reports on a single megapolitan area, recognizes a more sophisticated technique for analyzing urban growth—that shared economic and quality of life interests are more important than physically growing together.
Scholars at Virginia Tech defined the megapolitans based on economic and growth patterns.
The Sun Corridor, which cuts across six counties from the border with Mexico to the center of Yavapai County, is the home of eight out of 10 Arizonans. In the next several decades, two out of three Americans will live in a megapolitan accounting for 60% of the population on only 10% of U.S. land.
Megapolitan offers a bold new picture of Arizona’s geography and its future opportunities and “megaton” challenges. This report presents a scenario for 2035 based on current trends. It analyzes the Sun Corridor and provides insights into the region’s global potential, water, governance, sustainability, and “trillion dollar questions.” It discusses the “tragedy of the sunshine” and asks the indispensable question: In 2035, do you want to live in the Sun Corridor?Includes bibliographical references (p. 51).Copyright by the Arizona Board of Regents for and on behalf of Arizona State University and its Morrison Institute for Public Polic

Afrofuturismo como alternativa para a construção de outros currículos de lazer
No full textO presente trabalho representa o cruzamento dos Estudos Culturais com os Estudos do Currículo e do Lazer. Nesse cruzo, discutem-se estratégias de formação curricular e subjetivação no mundo pós-colonial, a partir da relação entre os conceitos de des-locamento e entre-lugares de Stuart Hall e Homi Bhabha. A noção de currículo, segundo Marlucy Paraíso, articulada com a diáspora dos povos africanos, na leitura de Paul Gilroy, pavimentam o estudo que propõe uma aproximação entre experiências pessoais descritas por Hall, Ebony Thomas e o autor deste artigo, para perceber o Afrofuturismo como uma alternativa para a construção de formas de currículo para o Lazer, as quais, ao invés de aprisionar, reativem forças, comprometendo-se com as relações étnico-raciais.The present study represents the cross between Cultural Studies and Curricular and Leisure Studies. At this intersection, strategies for curriculum formation and subjectivity in the postcolonial world are discussed, based on the relationship between the concepts of dis-placement and inter-places of Stuart Hall and Homi Bhabha. The notion of curriculum, according to Marlucy Paraíso, articulated with the diaspora of African people, in the reading of Paul Gilroy, opens the path for the study that proposes an approximation between the personal experiences described by Hall, Ebony Thomas and the author of this article, to perceive Afrofuturism as an alternative for the construction of forms of curriculum for the leisure, which, instead of imprisoning, reactivate forces, committing themselves to ethnic-racial relationships.info:eu-repo/semantics/publishedVersio
More Employers, More Jobs, More Money: An Empirical Analysis of Local Economic Development Policy Impacts in U.S. Cities
No full textLocal government leaders in the U.S. employ a multitude of programs and policies in the name of economic development to increase the number of firms, employment, wages, and, of course, the tax base. The past few decades have seen a surge in local economic development policies, yet research analyzing their effectiveness is sparse. This study analyzes the relationship between local economic development policy and economic growth in a data set of 412 U.S. cities. Results indicate that policy has only has a weak correlation with economic growth, suggesting that growth is determined more by market conditions rather than government intervention. The article concludes with an entrepreneurial policy approach this author believes may yield development results in an era of limited policy effectiveness.Economic development, Cities, Attraction, Retention, Incentives
