Global Superstardom: Applying a Multinational and Quantitative Approach to Explain the Success of the Korean Pop Music Industry
Full text linkKorean pop music (K-pop) has exploded in popularity around the world, first spreading to neighboring countries before successfully expanding into countries with greater cultural distances, challenging conventional wisdom. This thesis explains the factors that drive K-pop’s unique success in the United States. By applying qualitative models like CAGE and Mode of Entry models from multinational management, this study finds that K-pop firms have relied on strategic partnerships to distribute music and mitigate cultural and administrative risks, but future goals of owning digital platforms and exporting the K-pop business model will require a stronger presence.
This study also extracts sonic features from Spotify and uses machine learning techniques to perform a logistic regression and determine if the novelty or typicality of K-pop songs compared to popular American songs is predictive of international success. This research then performs a Latent Dirichlet Allocation (LDA) topic model on K-pop song lyrics to determine if there are differences in topic distributions between internationally successful K-pop songs and just domestically successful K-pop songs. The results are compared against those of another topic model performed on Billboard song lyrics. The findings indicate that typicality is a positive, statistically significant predictor of international success, and internationally successful K-pop songs over-represent specifically on topics that also appear in American songs compared to domestically successful K-pop songs. These findings shed light on aspects of K-pop firm actions and music that may be more critical to international success and carry managerial implications for firms looking to appeal to a global audience
Antitrust Policy and Facebook’s Acquisition of Small Rivals
Full text linkThis paper examines how current antitrust law can be better interpreted to address Facebook’s alleged unfair monopoly. It begins with an overview of applicable antitrust laws, then investigates how Section 2 of the Sherman Act can better be utilized. The paper delves into each component of the rule that is required to find a violation, compares the indirect and direct methods of proving monopoly power, proposes various methods of direct proof, and argues that agencies and courts should also include Facebook’s acquisitions of smaller rivals in their analyses of the firm’s anticompetitive conduct. The paper also briefly examines Section 7 of the Clayton Act and why the FTC may have relied on Section 2 of the Sherman Act instead. Ultimately, the paper finds that existing antitrust law is sufficient; however, agencies and courts should consider different ways of interpreting and applying them
Collation Model for LJS 416: [Regulations for mills and bakeries].
Full text linkOfficial copies of regulations pertaining to mills and bakeries in Rouen from the 14th century up to 1518. The copies were made at the request of Pierre Tassel, overseer of the Rouen mills (fermier des moulins de la dit ville de Rouen), under the supervision of Louis (Loys) Cruchon, a member of the Rouen parliament, who signed the manuscript repeatedly (f. 9v, 13v, 16r).https://repository.upenn.edu/sims_models/1009/thumbnail.jp
Collation Model for LJS 29: Extratto da un libro de razza da cavalli...
Full text linkLJS 29 is a treatise in 84 chapters on the anatomy, medical treatment, physical appearance, breeding, training, and care of horses. The manuscript claims to be an abridgment of an otherwise unknown work by Ferdinand I of Naples, an avid horseman.https://repository.upenn.edu/sims_models/1004/thumbnail.jp

Also includes a chronicle of the abbey of St. Nicholas in Sebenico from 1421-1453 (f. 73r-75r), by Stephanus Bilicich. Folios 75v-79r are blank. Also includes a miscellany, primarily in the hand of Stephanus Bilicich (f. 79v-94v); includes a cryptogram (f. 80r), prayers, proverbs, recipes (including for ink) and an Italian poem (f. 88r; this poem has one line for every letter of the alphabet).https://repository.upenn.edu/sims_models/1014/thumbnail.jp
Retirement Security and Health Costs
Full text linkHealth care spending has increased faster than incomes for decades, but the pace slowed materially after the passage of the Affordable Care Act (ACA). Using data from various waves of the Medicare Current Beneficiary Survey we examine what has happened to out-of-pocket health care spending by different income groups of the elderly over time, and how that has affected resources available for other consumption. We find that the slower pace of health care spending from the ACA was particularly beneficial to the elderly, who spend a greater share of income on health care than the nonelderly. We then examine how out-of-pocket spending on health care by the elderly will change going forward, given current projections for health care spending to accelerate again, and show that resources available for other spending may fall appreciably for lower income groups

NF-κB perturbation reveals unique immunomodulatory functions in Prx1 + Fibroblasts that Promote Development of Atopic Dermatitis
Full text linkSkin is composed of diverse cell populations that cooperatively maintain homeostasis. Up-regulation of the nuclear factor кB (NF-кB) pathway may lead to the development of chronic inflammatory disorders of the skin, but its role during the early events remains unclear. Through analysis of single-cell RNA sequencing data via iterative random forest leave one out prediction, an explainable artificial intelligence method, we identified an immunoregulatory role for a unique paired related homeobox-1 (Prx1)+ fibroblast subpopulation. Disruption of Ikkb-NF-кB under homeostatic conditions in these fibroblasts paradoxically induced skin inflammation due to the overexpression of C-C motif chemokine ligand 11 (CCL11; or eotaxin-1) characterized by eosinophil infiltration and a subsequent TH2 immune response. Because the inflammatory phenotype resembled that seen in human atopic dermatitis (AD), we examined human AD skin samples and found that human AD fibroblasts also overexpressed CCL11 and that perturbation of Ikkb-NF-кB in primary human dermal fibroblasts up-regulated CCL11. Monoclonal antibody treatment against CCL11 was effective in reducing the eosinophilia and TH2 inflammation in a mouse model. Together, the murine model and human AD specimens point to dysregulated Prx1+ fibroblasts as a previously unrecognized etiologic factor that may contribute to the pathogenesis of AD and suggest that targeting CCL11 may be a way to treat AD-like skin lesions. © 2022 The Authors, some rights reserve
Snag Availability and Preference of Cavity-Nesting Species in Philadelphia Urban Parks
Full text linkIn addition to habitat destruction and fragmentation, the removal of standing dead trees, known as snags, for safety and aesthetic purposes has increased pressure on cavity-nesting species to find resources for shelter, food, and nesting especially in isolated urban forest islands. Forested, riparian habitat in two Philadelphia urban parks (Wissahickon Valley Park and Cobbs Creek Park) was monitored for cavity nesting in four 0.5-acre circular sampling plots to determine their habitat suitability. Bird presence and nests were recorded during the nesting season of mid-April through mid-July in 2021 and 2022. Habitat assessments were completed in November 2021 and April 2022. Dead or dying trees (snags), as well as living trees with cavities, were also recorded and categorized by species and diameter at breast height. Across all plots, the most abundant cavity-nesting species in 2021 and 2022 was the Red-bellied Woodpecker (Melanerpes carolina) while Plot C1 had the most standing deadwood. Information from this study could be used to inform management of forest islands and urban parks through nesting box programs, snag maintenance, and greater conservation efforts to improve biodiversity. Despite forest islands such as Cobbs Creek Park and Wissahickon Valley Park being adversely affected by a lack of resources, they still offer crucial habitat for many bird species, especially cavitynesters. However, many forest islands could improve through nesting box programs, snag maintenance, and biodiversity conservation. Therefore, it is important to work on conserving the remaining woodlands of the east coast, reconnecting isolated patches where possible, and encouraging the overall health and biodiversity of these forests so that they can support and encourage healthy bird populations with an emphasis on the less well-known cavity nesting species that have more limited nesting opportunities
