Beyond causal explanation: Einstein’s principle not reichenbach’s
No full textOur account provides a local, realist and fully non-causal principle explanation for EPR correlations, contextuality, no-signalling, and the Tsirelson bound. Indeed, the account herein is fully consistent with the causal structure of Minkowski spacetime. We argue that retrocausal accounts of quantum mechanics are problematic precisely because they do not fully transcend the assumption that causal or constructive explanation must always be fundamental. Unlike retrocausal accounts, our principle explanation is a complete rejection of Reichenbach’s Principle. Furthermore, we will argue that the basis for our principle account of quantum mechanics is the physical principle sought by quantum information theorists for their reconstructions of quantum mechanics. Finally, we explain why our account is both fully realist and psi-epistemic
Small-Scale Experiment on Steel Tanks Subjected to Fire
Get PDFFor more than a century, oil storage disasters have damaged the environment and economy. These have become more common due to increased demands of petroleum for modern-day needs. In recent decades, research has been done computationally to better understand exactly what happens to tanks under a thermal load and why these disasters continue to occur regardless of updated standards. As physical research capabilities are limited due to the aforementioned damage caused by these disasters, this study aims to prove that small-scale testing could be implemented and pave the way for further research without the detrimental effects. The main objective of this study is to conceptually prove that small-scale testing is viable. This objective is encompassed through two goals: to measure and record a thermal gradient around the circumference of a small-scale model, and to induce buckling. While determining a thermal gradient on a small test subject was relatively simple, attempting to induce buckling was unfortunately indeterminable through these tests
Luminescent Metal-Organic Frameworks for the Detection of Alcohols
No full textMetal-organic frameworks (MOFs), porous materials composed of metal ions and organic linkers, have broad applications in separation, small molecule storage, and catalysis. Luminescent metal-organic frameworks (LMOFs) hold great potential in the development of sensors, and, with their relatively straightforward syntheses that produce predictable, homogeneous, extended structures, should result in good sensor-to-sensor reproducibility and uniform response. In addition, subtle differences in overall LMOF structure, metal ion coordination, pore surfaces, and host-guest interactions within pores should have significant impact on observed photoluminescence and provide numerous strategies for analyte detection, which shows promise for the detection of alcohols. Highlighted here is the development of LMOFs composed of zinc ions that incorporate luminescent osmium complex into the framework structure and the excitation and emission spectra of these materials in the presence of small molecules of varying polarity. The effect of the organic linkers within the MOF scaffold on the luminescence osmium was also studied
Exploring the Use of Occupational Therapy Telehealth Services in Early Intervention During COVID-19
Get PDFDuring the COVID-19 pandemic, the use of telehealth has increased significantly, including for occupational therapy (OT) services provided in the early intervention (EI) setting. While preliminary research evaluates the effectiveness and benefits of telehealth services in early intervention occupational therapy (EI OT), few studies compare telehealth to traditional in-person services. The purpose of this research study is to understand experiences with telehealth for EI OT services during COVID-19 as compared to experiences with previous in-person services from the perspective of OTs and parents. Using a qualitative case study design, interviews were conducted with one EI OT practitioner and two of their patient families. Major results identified using thematic content analysis include positive aspects of telehealth, such as increased access to the service provider, flexibility, and limited exposure to illness in general, as well as challenges to the use of telehealth, including significant safety concerns and problems associated with the lack of physical interaction and in-person services, resulting in perceived ineffectiveness of telehealth for specific EI OT services, dependent on the type of service. These findings add to existing research by identifying aspects of telehealth services that need to be considered by EI OTs when evaluating whether telehealth is an appropriate form of service delivery, as well as identifying aspects that may need to be adapted in order to increase feasibility and safety of telehealth services
The Complicated Spirituality of Pietist Conversion - Dale Brown Book Award Lecture
No full textJonathan Strom explores how the desire of German Pietists to determine “true conversion” distorted the understanding of conversion experiences and worked at cross purposes to the spirituality Pietists hoped to instill. Strom is senior associate dean of faculty and academic affairs and professor of church history at Candler School of Theology, Emory University, in Atlanta, Georgia. His recent book, German Pietism and the Problem of Conversion (Pennsylvania State University Press, 2018), received the 2019 Dale W. Brown Book Award
“Bread and not too much talking!”: The Role of the Peasant in the French Revolution
Get PDFThe French Revolution of 1789 is arguably the most significant set of uprisings in modern European history. While the peasants neither started nor finished the revolution, they did have a profound impact on furthering the revolution at certain times, especially during the Great Fear. The main questions I will be asking are: To what extent did the peasants have a role in elections to the Estates General? To what extent did peasants shape the list of grievances that representatives of the Third Estate took to the Estates General? Why and how did the peasants accelerate the revolution at key moments while never taking control of the government? To what extent did the Estates General, and subsequent assemblies, address the concerns of peasants? The main historians I have looked at are Georges Lefebvre, Albert Mathiez, Francois Furet, Alfred Cobban, John Markoff, and William Doyle. Based on the research conducted, I will argue that the role of the peasant was paramount to furthering revolutionary sentiments and stimulating reforms
That’s News to Me: A Content Analysis of the Portrayal of Perpetrators of Mass Murder in Mass Media Communications
Get PDFThe United States holds only five percent of the world’s population, but surprisingly 31 percent of global mass shootings. Previous literature defines a mass shooting as an incident where at least four individuals are shot and a mass murder as an incident where at least four individuals are killed. Mass shootings have been found to occur in bunches due to the exposure of mass shootings inspiring copycat shootings. Such inspiration has been potentially linked to media coverage of these events thus giving them “accidental advertising”. Limited research has empirically examined the news coverage of mass shootings through a content analysis. This exploratory research used quantitative and thematic content analysis to examine two qualitatively different mass shootings, the Las Vegas Concert shooting and the Dayton Nightclub shooting, and the news coverage of each event. The data for this research were obtained from a content analysis of articles from a local Las Vegas news website, The Las Vegas Sun, a local Dayton, OH news website, The Dayton Daily News, and AP News. Results will be presented and compared to the proposed guidelines for the coverage of mass shootings by media organizations
A Survey of Hydra Species in Selected South Central Pennsylvania Lakes
Get PDFSpecies of the genus Hydra are freshwater invertebrates present in lentic ecosystems around the world. Research on the phylogeny and biogeography of the genus has identified four species groups. However, little work has been done on Hydra ecology during the last forty years, even though the freshwater habitats where they are found are often substantially impacted by human activities. Our project aimed to characterize the distribution of Hydra species in selected lakes in south central Pennsylvania. We sampled six lakes within Lancaster and Dauphin counties. Based on preliminary sampling of a lake on the Elizabethtown campus, we hypothesized that the species H. oligactis and H. vulgaris would be present in all locations. Plant material was gathered from lake bottoms near shore and examined for Hydra using stereoscopic microscopes. Hydra species were identified based on bud morphology and structure of nematocysts, and detection probabilities for each species were estimated using the program MARK. Hydra were found from all four species groups and at all six locations, although the lakes varied in size, dissolved oxygen levels, and whether an inflowing stream was present
The Implications of Greek, Turkish, and U.S. Triangular Relations on Transatlantic Security
Get PDFSince the discovery of hydrocarbon resources in the Eastern Mediterranean, tensions between Turkey and Greece have been exacerbated due to enhanced geostrategic competition in the region (Dursun-Ozkanca 2021). Against the background of Turkey’s increased self-confidence in its foreign policy in the region and its “Blue Homeland” doctrine on maritime claims in the Eastern Mediterranean (Gingeras 2020) as well as its changing relations with the EU and the US, the need for scholarly analyses of regional competition in the Eastern Mediterranean and its implications for transatlantic security relations has become more evident. While there have been few academic works focusing on the diplomatic row between Turkey and Greece in the 1990s (Öymen 2000; Bağcı 2001; Missiroli 2002; Bilgin 2003; Tsakonas 2008), there is no theoretically informed and up-to-date analysis of the developments in the Eastern Mediterranean in the literature. Several solutions have been proposed, but some are unrealistic or attempt to address the entirety of the problem at once. Instead, I propose cementing foundational relations through commercial diplomacy – a strategy backed by the U.S. Department of State in the recently publicized ten-year Global Fragility Plan (United States Strategy to Prevent Conflict and Promote Stability, 2020)
