A Rich Reward in Tears: Hippolytus and Phaedra in drama, dance, opera and film

This thesis is a study of thematic clusters in the performance reception of the Hippolytus and Phaedra tradition – the body of reception material based on Euripides’ Hippolytus, Seneca’s Phaedra, and/or Racine’s Phèdre. This is the first comprehensive study of these three major source texts as a collective whole, challenging not only the idea of a single original ‘source text’, but also the idea of a directly linear reception pattern. I visualise the reception of the Hippolytus and Phaedra tradition as a porous membrane, containing a number of different items, from texts to performances, interacting in a multi-dimensional, fluid way, manifesting itself in different forms depending on the political, social, historical or literary context in which this story has emerged since Racine himself reworked Euripides and Seneca in the late seventeenth century. Each chapter has a particular thematic focus, within which I provide more detailed case study analyses from particular works across multiple genres. The Introduction provides close readings of the source texts and outlines my cross-genre theoretical framework. The second chapter focusses on the question of consanguinity and the impact of the incest motif on early adaptations. In the third chapter, I explore two 20th-century adaptations, both of which emerged during a decade dominated by Freud’s discoveries. In the fourth chapter, I focus on adaptations that explore and problematise Hippolytus’ sexuality. My fifth chapter focuses exclusively on the operatic and dance traditions, arguing that these genres lead to a prioritisation of the Phaedra character. The thesis concludes with a final chapter which traces the role of the divine within the reception tradition of Hippolytus and Phaedra examining in particular how recent adaptations move away from an earlier focus on psychology and human emotion to a new emphasis on the supernatural forces in the wider world

A Qualitative Evaluation of the Commissioners Court Leadership Academy

The Texas A&M AgriLife Extension Service created the V.G. Young Institute of County Government to provide educational programs for Texas county officials. The Commissioners Court Leadership Academy (CCLA) is a two-year leadership development program that provides leadership education and development for Texas county commissioners and judges, having implications for community leadership and service throughout the state. The CCLA program has not been evaluated on any level since its creation in 2005. Also, there is a gap in the literature as it pertains to the evaluation of agricultural leadership development programs for county government. The purpose of this study was to conduct an evaluation of the CCLA program, identify impacts of the program, and determine potential ways to improve the program. The study used qualitative research methods to explore the experiences and opinions of 11 graduates of the CCLA program representing different classes. Semi-structured interviews were conducted with the participants of this study, and documents were collected from the participants to document impacts of the program. Common themes were formed from the data collection. It was found that participants described the CCLA program based on their factors for why they chose to participate, the program’s structure in terms of sessions and time, and the program’s execution in terms of the met objectives and factors for success. It was also found that participants described the impacts of the CCLA program as affective outcomes, behavioral outcomes, and cognitive outcomes. An overarching outcome of the CCLA program that affected other impacts of the program for participants was their gained network of relationships. According to the findings of this study, the CCLA program has identified strengths as well as areas for improvement. The researcher made several recommendations for further research and changes to the program based on the study’s conclusions. This study provides the CCLA program with a more complete outlook of the program’s merits, deficiencies, impacts, and areas for improvement or change

Civic engagement, pedagogy, and information technology on Web sites for youth

Scholars of political socialization are paying increasing attention to how the Internet might help cure the civic disengagement of youth. This content analysis of a sample of 73 U.S.-based civic Web sites for youth introduces a framework for evaluating Web sites’ strategies for fostering active communication for citizenship. We offer the first systematic assessment of the extent to which a broad range of Web sites aim to develop young people’s abilities to use information and communication technology (ICT) as a vehicle for civic participation and to engage with ICT as a policy domain that encompasses issues (such as freedom of speech and intellectual property rights) that shape the conditions for popular sovereignty online. The study finds low levels of interactive features (such as message boards) that allow young people to share editorial control by offering their own content. In addition, few sites employ active pedagogical techniques (such as simulations) that research suggests are most effective at developing civic knowledge, skills, and participation. We also find little attention to ICT policy issues, which could engage budding citizens in debates over the formative conditions for political communication in the information age. We conclude with suggestions for civic Web site designers and hypotheses for user studies to test

Games for civic learning: A conceptual framework and agenda for research and design

Scholars, educators, and media designers are increasingly interested in whether and how digital games might contribute to civic learning. However, there are three main barriers to advancing understanding of games’ potential for civic education: the current practices of formal schooling, a dearth of evidence about what kinds of games best inspire learning about public life, and divergent paradigms of civic engagement. In response, this article develops a conceptual framework for how games might foster civic learning of many kinds. The authors hypothesize that the most effective games for civic learning will be those that best integrate game play and content, that help players make connections between their individual actions and larger social structures, and that link ethical and expedient reasoning. This framework suggests an agenda for game design and research that could illuminate whether and how games can be most fruitfully incorporated into training and education for democratic citizenship and civic leadership

Portrayals of information and communication technology on World Wide Web sites for girls

This study reports a content analysis of 35 World Wide Web sites that included in their mission the goal of engaging girls with information and communication technology (ICT). It finds that sites emphasize cultural and economic uses of ICT, doing little to foster civic applications that could empower girls as citizens of the information age. The study also finds that sites foster a narrow range of ICT proficiencies, focusing mostly on areas such as communication, in which girls have already achieved parity with boys. An examination of the role models portrayed in ICT occupations indicates that the sites show females mainly in elite technology jobs, reversing stereotypical mass media depictions of females in low-status roles in relation to ICT. Employing an original index of ICT knowledge and skills, the study finds that the sites that scored highest both on fostering comprehensive knowledge and skills as well as featuring civic content were general interest Web communities. Ownership (for-profit or not-for-profit) of sites was less important than editorial control: Sites that offered girls a place to contribute their own content were more likely to offer civic material and a broader range of ICT knowledge and skills. We conclude with recommendations for Web site designers to rethink their design strategies and their rationales for closing the gender gap in computing

Determining a robust indirect measurement of leaf area index in California vineyards for validating remote sensing-based retrievals

Accurate ground-based measurements of leaf area index (LAI) are needed for validation of remote sensing-based retrievals used in models estimating plant water use, stress, carbon assimilation and other land surface processes. Several methods for indirect LAI estimation with the Plant Canopy Analyzer (PCA, LAI-2200C, LI-COR, Lincoln, NE, USA) were evaluated using destructive (direct) leaf area measurements in three split-canopy vineyards and one double-vertical vineyard in California, as part of the Grape Remote sensing and Atmospheric Profile and Evapotranspiration eXperiment (GRAPEX). A method with the sensor facing the canopy, and four readings occurring evenly across the interrow space, had a coefficient of determination (R2) of 0.87 and relative root mean square error (RRMSE) of 16%, when compared to direct LAI measurements via destructive sampling. A previously used method, with the sensor facing down-row, showed lower correlation to direct LAI (R2 = 0.75, RRMSE = 33%) and underestimation which was mitigated by removing the outer sensor rings from analysis. A PCA method is recommended for rapid and accurate LAI estimation in split-canopy vineyards, though local calibration may be required. The method was tested within small units of ground surface area, which compliments high-resolution datasets such as those acquired by small unmanned aerial vehicles. The utility of ground-based LAI measurements to validate remote sensing products is discussed.info:eu-repo/semantics/acceptedVersio

To What Extent Does the Eddy Covariance Footprint Cutoff Influence the Estimation of Surface Energy Fluxes Using Two Source Energy Balance Model and High-Resolution Imagery in Commercial Vineyards?

Validation of surface energy fluxes from remote sensing sources is performed using instantaneous field measurements obtained from eddy covariance (EC) instrumentation. An eddy covariance measurement is characterized by a footprint function / weighted area function that describes the mathematical relationship between the spatial distribution of surface flux sources and their corresponding magnitude. The orientation and size of each flux footprint / source area depends on the micro-meteorological conditions at the site as measured by the EC towers, including turbulence fluxes, friction velocity (ustar), and wind speed, all of which influence the dimensions and orientation of the footprint. The total statistical weight of the footprint is equal to unity. However, due to the large size of the source area / footprint, a statistical weight cutoff of less than one is considered, ranging between 0.85 and 0.95, to ensure that the footprint model is located inside the study area. This results in a degree of uncertainty when comparing the modeled fluxes from remote sensing energy models (i.e., TSEB2T) against the EC field measurements. In this research effort, the sensitivity of instantaneous and daily surface energy flux estimates to footprint weight cutoffs are evaluated using energy balance fluxes estimated with multispectral imagery acquired by AggieAir sUAS (small Unmanned Aerial Vehicle) over commercial vineyards near Lodi, California, as part of the ARS-USDA Agricultural Research Service’s Grape Remote Sensing Atmospheric Profile and Evapotranspiration eXperiment (GRAPEX) project. The instantaneous fluxes from the eddy covariance tower will be compared against instantaneous fluxes obtained from different TSEB2T aggregated footprint weights (cutoffs). The results indicate that the size, shape, and weight of pixels inside the footprint source area are strongly influenced by the cutoff values. Small cutoff values, such as 0.3 and 0.35, yielded high weights for pixels located within the footprint domain, while large cutoffs, such as 0.9 and 0.95, result in low weights. The results also indicate that the distribution of modelled LE values within the footprint source area are influenced by the cutoff values. A wide variation in LE was observed at high cutoffs, such as 0.90 and 0.95, while a low variation was observed at small cutoff values, such as 0.3. This happens due to the large number of pixel units involved inside the footprint domain when using high cutoff values, whereas a limited number of pixels are obtained at lower cutoff values

Implications of Soil and Canopy Temperature Uncertainty in the Estimation of Surface Energy Fluxes Using TSEB2T and High-Resolution Imagery in Commercial Vineyards

Estimation of surface energy fluxes using thermal remote sensing–based energy balance models (e.g., TSEB2T) involves the use of local micrometeorological input data of air temperature, wind speed, and incoming solar radiation, as well as vegetation cover and accurate land surface temperature (LST). The physically based Two-source Energy Balance with a Dual Temperature (TSEB2T) model separates soil and canopy temperature (Ts and Tc) to estimate surface energy fluxes including Rn, H, LE, and G. The estimation of Ts and Tc components for the TSEB2T model relies on the linear relationship between the composite land surface temperature and a vegetation index, namely NDVI. While canopy and soil temperatures are controlling variables in the TSEB2T model, they are influenced by the NDVI threshold values, where the uncertainties in their estimation can degrade the accuracy of surface energy flux estimation. Therefore, in this research effort, the effect of uncertainty in Ts and Tc estimation on surface energy fluxes will be examined by applying a Monte Carlo simulation on NDVI thresholds used to define canopy and soil temperatures. The spatial information used is available from multispectral imagery acquired by the AggieAir sUAS Program at Utah State University over vineyards near Lodi, California as part of the ARS-USDA Agricultural Research Service’s Grape Remote Sensing Atmospheric Profile and Evapotranspiration eXperiment (GRAPEX) project. The results indicate that LE is slightly sensitive to the uncertainty of NDVIs and NDVIc. The observed relative error of LE corresponding to NDVIs uncertainty was between -1% and 2%, while for NDVIc uncertainty, the relative error was between -2.2% and 1.2%. However, when the combined NDVIs and NDVIc uncertainties were used simultaneously, the domain of the observed relative error corresponding to the absolute values of |ΔLE| was between 0% and 4%
