A Student\u27s Reflections on Service: What Is Service? Why Serve?

There is an old story about an ancient Greek philosopher named Thales. According to this tale, Thales was looking to the stars as he walked about Athens, attempting to answer certain troubling philosophical questions. He became so engaged in thought that he didn\u27t even notice the well he was approaching. Needless to say, Thales. one of the most brilliant of ancient Greek philosophers. fell into the well and became the butt of many Athenian jokes. His head was so lost in the clouds, some said, that he didn\u27t even notice the world around him

The Misgivings of a Pop Culture Enthusiast: On the intersection of philosophy and entertainment

In recent years, dozens of books on philosophy and popular culture have been published. These books have been subjected to a number of criticisms in a number of venues—including other popular philosophy venues. In this paper, I will examine several versions of the criticism that such endeavors are frivolous entertainment. I will argue that, though most of these criticisms do not stand up to scrutiny, they nevertheless express a legitimate worry about the intercourse of philosophy and entertainment. This, I contend, is a criticism the ‘philosophy and popular culture’ genre must live with—and one that cannot easily be dismissed

Heidegger, Arthur Fine, and the Natural Ontological Attitude

In this paper I argue that Arthur Fine and Martin Heidegger present responses to the dispute between realism and antirealism that are remarkably close in character. Both claim that this dispute arises from a failure to take seriously our everyday experience of things in the world. I argue that it is useful to note the similarity between Fine and Heidegger for two distinct reasons: 1) their view provides a viable alternative to the current realist/antirealist dispute–an alternative that has not been given its due, and 2) it allows us to build a bridge between two seemingly distinct traditions

Variability of Disk Emission in Pre-Main Sequence and Related Stars. I. HD 31648 and HD 163296 - Isolated Herbig Ae Stars Driving Herbig-Haro Flows

Infrared photometry and spectroscopy covering a time span of a quarter century are presented for HD 31648 (MWC 480) and HD 163296 (MWC 275). Both are isolated Herbig Ae stars that exhibit signs of active accretion, including driving bipolar flows with embedded Herbig-Haro (HH) objects. HD 163296 was found to be relatively quiescent photometrically in its inner disk region, with the exception of a major increase in emitted flux in a broad wavelength region centered near 3 microns in 2002. In contrast, HD 31648 has exhibited sporadic changes in the entire 3-13 micron region throughout this span of time. In both stars the changes in the 1-5 micron flux indicate structural changes in the region of the disk near the dust sublimation zone, possibly causing its distance from the star to vary with time. Repeated thermal cycling through this region will result in the preferential survival of large grains, and an increase in the degree of crystallinity. The variability observed in these objects has important consequences for the interpretation of other types of observations. For example, source variability will compromise models based on interferometry measurements unless the interferometry observations are accompanied by nearly-simultaneous photometric data.Comment: 55 pages, 18 figures, 2 tables, Accepted by Ap

Heidegger’s Underdeveloped Conception of the Undistinguishedness (Indifferenz) of Everyday Human Existence

This chapter provides an interpretation of the early Heidegger’s underdeveloped conception of the undistinguishedness of everyday human existence in Being and Time. After explaining why certain translation choices of some key terms in this text are interpretively and philosophically important, I first provide a concise argument for why the social constitution interpretation of the relation between ownedness and unownedness makes better overall sense of Heidegger’s ambivalent attitude toward the social constitution of the human being than the standard existentialist interpretation of this relation. I then proceed to the heart of this chapter, which develops his inchoate conception of the undistinguishedness of everydayness by arguing that it specifies the third distinctive mode of concrete human existence in addition to ownedness and unownedness. Accordingly, I show how unownedness is actually a generic phenomenon with two distinct species, namely, undistinguishedness and disownedness, which are at once closely related to, but also differ in significant respects from, each other. Consequently, instead of taking for granted a one-dimensional and mutually exclusive opposition between ‘authenticity’ and ‘inauthenticity’, I argue that we should adopt a two-dimensional and more nuanced understanding of the relations among undistinguishedness, disownedness, and ownedness that intersects with Heidegger’s underappreciated distinction between genuineness and ungenuineness. After raising and replying to some objections to this interpretation of undistinguishedness, I conclude this chapter by briefly sketching three of its philosophical consequences and pointing out its potential as an important resource for contemporary social theories

The fire toxicity of polyurethane foams [Review]

Polyurethane is widely used, with its two major applications, soft furnishings and insulation, having low thermal inertia, and hence enhanced flammability. In addition to their flammability, polyurethanes form carbon monoxide, hydrogen cyanide and other toxic products on decomposition and combustion. The chemistry of polyurethane foams and their thermal decomposition are discussed in order to assess the relationship between the chemical and physical composition of the foam and the toxic products generated during their decomposition. The toxic product generation during flaming combustion of polyurethane foams is reviewed, in order to relate the yields of toxic products and the overall fire toxicity to the fire conditions. The methods of assessment of fire toxicity are outlined in order to understand how the fire toxicity of polyurethane foams may be quantified. In particular, the ventilation condition has a critical effect on the yield of the two major asphyxiants, carbon monoxide and hydrogen cyanid

MIF is a common genetic determinant of COVID-19 symptomatic infection and severity

Genetic predisposition to coronavirus disease 2019 (COVID-19) may contribute to its morbidity and mortality. Because cytokines play an important role in multiple phases of infection, we examined whether commonly occurring, functional polymorphisms in macrophage migration inhibitory factor (MIF) are associated with COVID-19 infection or disease severity.This work was supported by National Institute of Health (NIH) [1R01-AR078334 (RB), 5R01-AI51306 (RB), R01-HL155948 (MS, RB), 1R01AG056728 (IK), T32AR07107 (JPY) and KL2 TR001862 (JJS)]; the European Commission (DB) – NextGenerationEU (Regulation EU 2020/2094) through CSIC's Global Health Platform (PTI Salud Global), and Junta de Castilla y León (Programa Estratégico Instituto de Biología y Genética Molecular (IBGM), Junta de Castilla y León (CCVC8485); and the National Natural Science Foundation of China [#81901669 (WF)].Peer reviewe
