Two-photon absorption and fluorescence of cadmium sulfide
The two-photon absorption and fluorescence of bulk cadmium sulfide were studied using 50-fs, 800-nm pulses from an unamplified Ti:sapphire laser. The fluorescence spectrum was measured to have a main peak at 522 nm, and the power of the fluorescence was shown to vary quadratically with the 800-nm beam power. This supports the theory that the fluorescence is excited by two-photon absorption and confirms previous work done with longer duration, higher energy excitation pulses. Pump-probe measurements provided additional confirmation of the two-photon absorption. Measured spectral broadening of the wings of the laser spectrum also was observed, which likely is due to self-phase modulation in the cadmium sulfide
Mexi-sotans & Minnesotanos: The Past, Present, and Future of Mexican and Latino Culture in the Bold North
Aaron Johnson-Ortiz -- Minnesota-based muralist, artist, cultural organizer, and arts administrator -- is the Executive Director of (Neo)Muralismos de México, and the Founder of the Minnesota Latino Museum. Aaron will share his upbringing shuttling between rural Minnesota, Saint Paul, Guatemala City, and San Cristobal de las Casas, Chiapas, Mexico; and trace the deep cultural history of Mexicans and Latinos in Minnesota: From the arrival in our state of Oaxaqueño flute-player Luis Garzon in 1886; to the Minnesota roots of Lila Downs, considered by many to be the most prominent contemporary Mexican singer; to the graphic design work of Luis Fitch, who chaired the committee to develop the new Minnesota State Flag; to the election in 2022 of Sota-Rican singer and hip-hop artist María Isa Pérez-Vega as MN State Representative; to the creation of an Ofrenda at the MN State Capitol in 2022, which led Minnesota to become the first state in the US to officially recognize Day of the Dead -- Minnesota Mexicans and Latinos punch way above our weight in terms of arts and cultural production. Lastly, Aaron will outline the historical and cultural impact of the Mississippi River -- how it has connected the geographic regions known today as the American Midwest and Latin America for centuries and even millennia. The Mississippi riverfront in Minnesota\u27s Capital City of Saint Paul is the site selected for the proposed Minnesota Latino Museum, which will honor those ancient connections, preserve Mexican and Latino cultural heritage in the Upper Midwest, and celebrate new and old art forms for generations to come
Emotions in Reading, Learning, and Communication
This book brings together experts engaging in empirical studies on how emotion influences learning and processing for varying text types in different contexts.
In our current era, learners are confronted with many and varying sources of information, such as news media, books, websites, social media, scientific articles, communicative interactions, and more. In addition, individuals must learn from such sources, making it important to critically examine the factors underlying learning from text and discourse. Importantly, the valence (pleasantness) and activation (intensity) of learners’ emotions can influence the quality of processing, which could help or hinder the learner’s ability to understand and learn from text. The chapters included in this book work toward developing a more comprehensive understanding of the influence of emotions in supporting learning, comprehension, processing, and conceptual change to draw important connections to the broader fields of text and discourse, learning, and motivation. --From publisher\u27s websitehttps://digitalcommons.csbsju.edu/academic_books/1009/thumbnail.jp
“Nueva refutación del tiempo [A New Refutation of Time] and the Portrayal of an Ironic Fate”
When the author was writing her PhD dissertation on David Hume at the Consejo Superior de Investigaciones Científicas (CSIC) in Madrid, back in 1981, she was unable to believe that a given literary production would shed so much light not just on Hume, but on the whole history of philosophy. It wasn’t until she came to the United States and plunged completely into Borges’s writings that she realized the magnitude of his erudition and philosophical competence. After completing her dissertation on Borges and Hume at the University of Virginia, she continued working on the scope and nature of Borges’s skepticism. Taking Kemp Smith’s interpretation of Hume (a critic cited in “Nueva refutación del tiempo” [A New Refutation of Time]), this chapter focuses on the role that both Hume’s skepticism and naturalism play in “Nueva refutación del tiempo,” a capital essay in Borges’s writings that should be fully viewed as a significant contribution in contemporary philosophy. --From publishe
Journey to Justice: Indigenous Partnerships at CSB+SJU
This panel discussion is focused on how student-led research and community organizing plays a central role in Native American boarding school truth and healing at CSB+SJU. The panel features Joe LaGarde, a White Earth elder and next-of-kin to John Parker, whose remains were recently returned to White Earth 134 years after he died while attending the St. John\u27s Industrial School. Joining Joe LaGarde are Moses Wiseman (SJU \u2723) , Adri Warden (CSB \u2722), Faith Gronda (CSB \u2722), and Marissa Johnson (CSB \u2722), co-founders of CSB+SJU\u27s Indigenous Students Association. These young alum led the call for our institutions to respond its boarding school legacies, work that is still transforming our communities today. The panel is facilitated by Ted Gordon, director of the Initiative for Native Nation Relations
Augustine\u27s Analogy: How to Say God
Augustine\u27s analogy of the Trinity regards the question of how to speak about God. Augustine maintained that human language and material images are limited in their ability to wholly capture the essence of God, who is beyond human comprehension. He understood that the language we use to describe God is necessarily metaphorical and analogical, as we cannot fully grasp the transcendent nature of the divine. By using analogy, Augustine aimed to help his audiences come to some rudimentary understanding of the Trinity. This paper argues that Augustine\u27s use of analogy provides a persuasive approach for understanding the Trinity. It focuses on three points: the application of analogy, the nature of the Trinity, and proof of the unity of God\u27s persons
Gluten-free Hosts and the Cross: Revelatory Suffering in Christianity
The body, blood, soul, and divinity of Jesus are said to be made present by the Eucharist: bread and wine placed on the altar. However, the Roman Catholic Church teaches there is no validity to consecrations with gluten-free Hosts. This article notes the past permissions on gluten-free hosts and explores how present and former practices exhibit the nature of the Crucifixion, humanity’s participation in a world it abuses, and, furthermore, how to remedy this source of exclusion
Different Forms of Power in Worship Spaces
This project examines the importance of power in a worship space. In particular, looking at the historical structures of St. Paul\u27s Cathedral in London and St. Basil\u27s Cathedral in Moscow, this paper strives to lay out the presence of power inherent in places of worship. While other aspects could be used: power as a political structure, power of shared identity, power of scale, and power as a means of limits are given here for consideration
The Concept of Suffering in Children of Heaven: Analyzing The Differences and Similarities Between Augustine’s and Ibn Arabi’s Theodicy
This article discusses the theodicy of Augustine and Ibn Arabi. Although these two theologians come from different traditions and backgrounds, they articulate that the realm of suffering in the human world can help us sharpen our faith in God. I use the movie Children of Heaven (by Majid Majidi) to parse the similarities and differences in their theologies. The symbols found in the movie show that the two theologies are related. This article explores the themes of human suffering in the movie and goes beyond a simple review
Income Differences Among Nations: Measuring the Effects of Human Capital on Total Factor Productivity (TFP)
In the past two centuries, long-term economic growth has been defined by The Great Divergence, where the gap of income distribution has widened as a result of some nations experiencing modern economic growth while others have remained stagnant in their economic well-being. This panel data research examines differences in income across countries by applying development accounting to analyze differences in per capita gross domestic product (GDP) and predict each country’s total factor productivity (TFP). Data from the Penn World Tables were collected and categorized into groups based on GDP per capita to create a sample of 144 countries in 10-year intervals from the years 1990-2019. Variables gathered from the Penn World Tables included engaged persons, capital stock, real GDP, and a human capital index. Through observing empirical evidence with economic data, significant evidence supports the hypothesis that human capital is influential in a country’s total factor productivity. Results of various analyses illustrate the significant impact income class has on the correlation between human capital and total factor productivity
