Reframing severed representations: from biography towards a psychoanalytical reading of Caravaggio’s self-portraiture
Get PDFPerhaps one of the most celebrated artists of all time and responsible for ushering in a new style of art during the Baroque period, Michelangelo Merisi da Caravaggio continues to emerge from the pages of history and captivate art historians and art lovers alike. He has been the focus of countless scholars and art critics since his emergence as an artist in 16th century Rome. This research will provide a fresh analysis of two of the artist\u27s verified self-portraits, The Young Sick Bacchus c. 1593 and David with the Head of Goliath c. 1610, using Lacanian psychoanalytic theory. By doing this, this research aims to present the possibility that by the end of his life, Caravaggio was concerned with issues of forgiveness as he waited for a papal pardon. One of his last works, David with the Head of Goliath, circa 1610, provides a clue that supports this idea, which will be examined later in this paper. Thus, arguing that while Caravaggio certainly had a flair for drama in both his work and personal life, he also strove to correct his behavior – or at the very least, was remorseful and desired absolution for his sins
Augmented Reality in a Dynamic Drone Based Environment
Get PDFAugmented Reality (AR) and Unmanned Ariel Vehicles (UAVs) are fast advancing technologies, and this research seeks to combine them to offer an effective, user friendly approach for monitoring infrastructure. Drones provide a means to easily access otherwise difficult to reach locations and visualize useful information with Augmented Reality. A UAV employs a wide-angle view and, when paired with AR, this will enable the user to better complete their task by effortlessly providing the critical information they need in the most intuitive way possible. This research is particularly applicable for civil applications such as construction and monitoring of difficult to access locations. The background for these technologies and applications will be discussed in the next section, but this research is unique in its combined and interactive application of AR and drone technology. Many existing techniques which are discussed in this paper already exist for general applications of AR. Using a drone feed compared to a relatively fixed camera creates many barriers to the AR process. This research explores how existing techniques perform under these conditions, such as fast moving cameras and complex environments that drones often face. This research also explores potential methods for improving accuracy for AR objects created on a Drone feed. Existing technology such as object tracking and image filtering are used to improve accuracy. Other simple mathematical methods are used, such as Kalman Filtering and data smoothing algorithms, to improve the appearance of the AR object in the frame
North and South Korea: division by constructions
Get PDFThis paper focuses on aspects of social identities that have been constructed over time in North and South Korea and their implications on the division of the Korean peninsula. This project seeks to answer the question of how social groups and individual dynamics differ between North Korea and South Korea with special attention to the experience of division? And, how these differences structure the dynamics of formal division and the larger politics of reunification? These questions have been ignored because of the emphasis on the realist and institutionalist scholars’ analysis of the division. It focus on analyzing the division through the constructivist lens of international relations. This research will identify a couple of social constructions that contribute to the division between the DPRK and the ROK and cause challenges for reunification at both the micro-, reunification of defectors, and the macro-, reunification of the entire peninsula, reunification. This research specifically looks at the Juche ideology constructed through history, discourse, and policy that differentiates the “us” from the “them” necessary for division in the DPRK (Nau 2007, 32). This study then analyzes the difference in language and how that constructs the division through distinct markers of dialects, lack of common words, and how it reinforces ideas. Through this research, it is clear that division is not a simple issue of state policy, state action, regime type, or economic system, but an issue of the social construction of identities such as the divergent identities of the ROK and the DPRK. Social construction and division are not limited to this case only but have large scale implications for other areas of the world that have divisions. This research shows that there is more to be observed in these areas such as ideology and how it came to be
Small stem assay for chestnut blight resistance in segregating half-sib and full-sib families of F2 and backcross hybrid chestnut trees
Get PDFChestnut breeders routinely screen hybrid chestnut seedling progeny for resistance to chestnut blight in an orchard setting – a process that takes five to seven years. A novel technique that allows for screening in the first and second growing season is known as a small stem assay. We screened 110 first-backcross seedlings and 98 third-backcross seedlings in a completely randomized design in 2017 (Gentner 2018). In 2018, an additional 391 F2 hybrid chestnut seedlings were screened in a randomized complete block design. All seedlings were inoculated with the chestnut blight causal organism Cryphonectria parasitica when stem diameters were greater than 4mm. The 2017 trial recorded the day on which the plant wilted, during both the 2017 and 2018 trial, canker length was measured and recorded. The 2017 trial gave insight to the rate at which different seed types wilted and the 2018 trial selected the very best of the F2s
What\u27s in a name? an assessment of degradation of women in the name of climbing routes
Get PDFGendered behavior is reinforced at an early age. In media, women are usually portrayed following gender stereotypical behaviors and are often sexualized, meaning that their worth is often determined by their body shape and clothing type and as such women are often wearing revealing clothing, following gender stereotypical behaviors, and portraying unrealistic body proportions (e.g., Gentlemen’s Quarterly Magazine; Collins, 2011). The representation of women in climbing media is similar to that of the general media. The present study focused on route names within the climbing community and presents a qualitative analysis on the sexism and other derogatory (i.e., overtly sexual) themes present within the names. We found that while a large number of routes had neutral names, approximately 6.6% included derogatory names toward multiple identities. Implications of derogatory names and directions for future research are discussed
HPLC detection of organic gunshot residues with silicone wristbands
Get PDFThe analysis of gunshot residue (GSR) is frequently used to aid in investigating firearm-related crimes. Typically, Scanning Electron Microscopy (SEM) is applied for inorganic analysis of elements such as lead, barium, and antimony to study GSR. However, heavy metal-free ammunition creates the need for a different type of approach. This research focuses on studying the potential of detecting organic gunshot residue (OGSR) collected with silicone wristbands through passive sampling. This study has been directed towards the development of an optimal High Performance Liquid Chromatography (HPLC) procedure for the detection and separation of five selected compounds typically found in OGSR. The chosen residues were dimethyl phthalate (DMP), diphenylamine (DPA), 2-nitrodiphenylamine (2-NDPA), 4-nitrodiphenylamine (4-NDPA), and ethyl centralite (EC). Through calculating figures of merit for different HPLC conditions, the most suitable mobile phase was determined to be water/acetonitrile (52:48) using a Poroshell 120 EC-C18 column with temperature programming. Other findings of this research showed that silicone wristbands are capable of adsorbing the selected compounds. These initial studies are expected to aid further research in OGSR as well as the use of silicone wristbands as passive sampling devices (PSDs)
Forest kindergarten and the perception of parents
Get PDFThis study investigates one public school forest kindergarten in the southeastern U.S. The purpose of this study is to determine the perception of parents of a kindergarten classroom context that is somewhat unique for U.S. public schools (forest kindergarten). The researcher believes that there is a unique perception that parents of forest kindergarten students have, and this study seeks to identify and describe them in order to inform 1) the participants and participating school system so that they can make informed decisions for this and future school-context reform models, and 2) the education research community at large so that U.S. public school efforts to enact forest kindergarten learning contexts can become part of the international conversation on early childhood learning contexts. The researcher’s questions were: What are the perceptions of parents that applied for their child to be in forest kindergarten compared to the parents that didn’t apply for forest kindergarten? The researcher is interested in the differences and similarities between parents of forest kindergarten and traditional kindergarten students. The findings indicate that parents of forest kindergarten students believe that forest kindergarten will allow students a better transition to school while still achieving grade level academic performance
Friendship and Informant Characteristics Associated with the Agreement among Adolescent and Friend Ratings of Behavior Problems
Get PDFThe present study investigated the relative agreement between adolescent self-reports and friend informant reports of behavior problems as well as factors that might impact this agreement. High school students were placed into friendship dyads based on perceived friendship closeness and rated friendship quality, their own internalizing and externalizing behavior problems, and the behavior problems of their matched friend. Self- and friend ratings demonstrated high levels of agreement across behavior problems presentations. Further, raters’ own behavior problems were related inconsistently to rating agreement, whereas friendship quality demonstrated some impact on the informant’s reports of specific behavior problems. This study provided additional support for the utility of friend informants when ratings of adolescents’ internalizing and externalizing behavior problems are needed
Misunderstanding and Misinformation: Safety risks and intervention strategies for two common workplace occurrences
No full textThere is an overwhelming amount of information cascading online and through the media each day. Unfortunately, it can be hard to distinguish fact from fiction. In organization, misinformation can include rumors regarding safety polices and practices, incidents that occurred in the workplace, or location openings/closings. Because of this, HR and HSE professionals may find themselves in a position where they need to correct misinformation or offer managers guidance on how to correct misinformation. Unfortunately, we can unintentionally reinforce or even spread misinformation while trying to correct it. Given the importance of decisions that need to be made in this time, we need to know how to spot useful information and learn how to open conversations with people who deny, ignore, or outright reject data and science. The session will explore reasons people discount (willfully or unwillingly) facts that conflict with their opinions or points of view, provide tactics HR and HSE professionals can use to critically evaluate information, and provide tools that can be used to correct misinformation effectively
Using the Job Demands-Resources model to predict burnout in police officers in the UK and the US
Get PDFThe Job Demands-Resources (JD-R) model has been used in a number of research studies to predict burnout among human service professionals, including police officers. Rates of burnout among police officers can vary widely between countries and types of officers, which necessitates further exploration of the workplace stressors and conditions that impact how and why police officers experience burnout. In this study I will examine data from two samples of police officers, one from the United Kingdom and one from the United States, to explore if certain demands and resources have different weights in contributing to burnout for police officers in different countries. Additionally, police have received significant media and public attention in the United States in recent years, which could be functioning as a unique stressor for police work. Thus, I will include exploratory research questions about officers’ perceptions of community support for police work in the American sample and how those portrayals could further impact burnout and health above and beyond their typical job demands
