Thoreau as Liberation Thinker

In lieu of an abstract, here is the article\u27s first paragraph: Henry David Thoreau’s claim to be “a mystic, a transcendentalist, and a natural philosopher” took an unexpected turn for me. Spending much time with A Week on the Concord and Merrimack Rivers (my dissertation addresses the idea of religion found between its covers), I encountered a “liberation thinker” resisting the limitations of American culture while honoring the natural world and indigenous peoples. Thoreau’s epigraph reveals how he wants the muse of his dead brother to inspire him, but the book also discloses how he wants the muse of indigenous peoples to inspirit and improve American culture. Impressively, he esteems nature as more than a symbol pointing to a distant divinity as he experiences its inherent sacredness. Natural creation is at once our house and being; we are immersed in and part of its continuous regenerative processes, which suggests familial bonds of sacredness uniting humans and nonhumans. Thoreau offers an alternative to social structures and outlooks that devalue human and nonhuman existence

In Defense of Alain Badiou

In lieu of an abstract, here are the article\u27s first two paragraphs: In Issue 107, Philosophy Now published James Alexander’s ‘A Refutation of Snails by Roast Beef\u27, an article decrying con temporary French philosopher Alain Badiou (b.l937). Alexander’s jumping-off point was Roger Scruton’s unfavorable review of Badiou’s The Adventure of French Philosophy (2012). He acknowledges that Scruton “obviously dislikes everything Badiou stands for” but takes Scruton to task for being too polite; he writes that “Badiou deserves derision.” A few sentences later, he claims that “a lot of Badiou is rubbish. There is nothing to Badiou be done with it except laugh.” Not even Badiou’s students escape Alexander’s comments: he scoffs that instead of taking notes in Badiou’s lectures, surely the students “just stand and cheer.” Although I might get much enjoyment from indulging in a similarly dismissive attitude toward Alexander’s largely ad hominem attacks against Badiou, I have chosen a different path in defending him. I honor the dialectical process of Socrates’ philosophical approach; therefore I offer a counterargument to expose the inaccuracy of Alexander’s underestimation of Badiou. I will not advance uninformed opinions based on insufficient familiarity (Alexander confesses a lack of knowledge of Badiou’s oeuvre). Instead, I offer a perspective based on an engagement with and a deep reverence for Badiou’s philosophy

The Value of Friendship for Education

In lieu of an abstract, here is the article\u27s first paragraph: Western philosophers have enthusiastically praised friendship. A few intellectuals have raised doubts about it, such as Thomas Hobbes and Søren Kierkegaard, but friendship has inspired many others, including Aristotle, Francis Bacon, C.S. Lewis, and Mary E. Hunt, who have esteemed its benefits, especially the reciprocal commitment to nurture each friend\u27s \u27best self\u27

Let\u27s Change the Subject: Grounding Social Change in Indigenous HIstory and Philosophy

This article urges altering the discourse around social change. Too often it is antagonistic and negative; it also overlooks continuing colonizing practices and how injustices to Indigenous peoples have helped to shape past and current injustices toward other groups. First, the article foregrounds the religio-political ideology of the Doctrine of Christian Discovery and the boarding-school experience to remind readers about the broader criminal history of the United States toward Indigenous nations and peoples and how colonization is not a thing of the past. Any call for social change should remember this. Second, the article looks at three dimensions of Indigenous philosophy that would be good to affirm as we strive for a better world: relatedness, sustained peace, and an ethic of preservative care. Limited calls for justice that avoid continuing colonizing practices and that begin with negations and hate are not responsible and will help to continue the sustained violence we no longer want. For sustained peace, the strategy should be to begin with an affirmation (here an affirmation of Indigenous wisdom) and a broader historical understanding of the injustices that continue to bring harm to millions of people within the borders of the United States. By changing the subject in this way, it will not only make for more peaceful activism, but it will also create better allies to Indigenous nations and peoples

Full phase stabilization of a Yb:fiber femtosecond frequency comb via high-bandwidth transducers

We present full phase stabilization of an amplified Yb:fiber femtosecond frequency comb using an intra-cavity electro-optic modulator and an acousto-optic modulator. These transducers provide high servo bandwidths of 580 kHz and 250 kHz for frep and fceo, producing a robust and low phase noise fiber frequency comb. The comb was self-referenced with an f - 2f interferometer and phase locked to an ultra-stable optical reference used for the JILA Sr optical clock at 698 nm, exhibiting 0.21 rad and 0.47 rad of integrated phase errors (over 1 mHz - 1 MHz) respectively. Alternatively, the comb was locked to two optical references at 698 nm and 1064 nm, obtaining 0.43 rad and 0.14 rad of integrated phase errors respectively

Indications for rootstock related ecological preferences of grape phylloxera (Daktulosphaira vitifoliae Fitch)

By parasitizing the roots of Vitis species, grape phylloxera (Daktulosphaira vitifoliae Fitch, Phylloxeridae) is one of the most devastating pests in viticulture. Grafting susceptible scions (Vitis vinifera) to tolerant Vitis rootstocks is a common practice to control grape phylloxera in wine growing regions worldwide. However, grape phylloxera populations still develop on the roots of most grafting combinations. Questions remain as to whether or not the impact of environmental factors on grape phylloxera population dynamics is related to Vitis rootstock cultivars. In the presented field study, we investigated the influence of two closely related mature Vitis berlandieri x Vitis riparia rootstock varieties on the relations between the dynamics of root feeding grape phylloxera populations, root morphology and abiotic factors. The investigation took place on a commercial vineyard in Geisenheim/Germany on Teleki 5C/V. vinifera 'Weisser Riesling' and Kober 125AA/V. vinifera 'Weisser Riesling'. Samples of roots, attached grape phylloxera populations and soil were taken in the field 19 times between August 2007 and August 2009. Grape phylloxera population structure was recorded by the occurrence of root-feeding wingless females, fundatrices and nymphs and the pigmentation and position of root galls were assessed. Root morphological parameters were assessed using WinRhizo Pro. Soil abiotic parameters were assessed in the laboratory. Results of a principal component analysis showed rootstock related differences considering the impact of abiotic factors on grape phylloxera population structure. Especially soil temperature and soil organic matter were indicated to have a lower impact on grape phylloxera population structure on roots of 5C than on roots of 125AA. Our data indicate that ecological factors have a lower impact on the development of grape phylloxera on more supportive rootstocks

Broadband Phase-Noise Suppression in a Yb-Fiber Frequency Comb

We report a simple technique to suppress high frequency phase noise of a Yb-based fiber optical frequency comb using an active intensity noise servo. Out-of-loop measurements of the phase noise using an optical heterodyne beat with a continuous wave (cw) laser show suppression of phase noise by \geq7 dB out to Fourier frequencies of 100 kHz with a unity-gain crossing of -700 kHz. These results are enabled by the strong correlation between the intensity and phase noise of the laser. Detailed measurements of intensity and phase noise spectra, as well as transfer functions, reveal that the dominant phase and intensity noise contribution above -100 kHz is due to amplified spontaneous emission (ASE) or other quantum noise sources.Comment: 4 pages, 3 figure
