    1. Pignons de pin de Corée et noix de ginkgonécessitent 2 mois à 20°C suivis de 3 mois au froid (4*).

      4* À défaut de leur laisser 2 mois de chaleur après la cueillette, ces noix germeront vers juillet-août seulement.

    2. Châtaignes, noix des Carpates etglands doux (3*) peuvent germer sans stratification au froid

      3* Se réfère au groupe des chênes blancs, prins, verts et d’Eurasie: chêne blanc, à gros fruits, bicolore, pédonculé et autres

    3. En principe, une période de froid (avoisinant 0-4° c) d’une durée de 3 mois minimum est nécessaire pourla plupart des noix de noyer, caryer, noisetier (1*) et pour les glands amers (2*).

      1* Nous avons vu des noisettes germer dès l’automne lorsqu’elles sont soumises à un fort taux d’humidité.

      2* Se réfère au groupe des chênes rouges: chêne noir, écarlate, des marais, ellipsoïdal et imbriqué.

    4. Il est possible de forcer la germination des semences en avril voire vital de le faire dans le cas de semences duresou de celles qui ont séché quelque peu. Voici la recette: les mettre dans du sable ou paillis très humide (saturé)jusqu’à ce que quelques semences ébauchent une germination; semer par la suite. Plusieurs professionnelsrecommandent de les laisser tremper 24 h dans l’eau. N’hésitez pas à ouvrir quelques noix pour voir l’état del’amande intérieure si vous avez des doutes sur la qualité des noix. Les noisettes et noix de pin peuvent êtrelégèrement craquées pour être semées par après.

      J'ai remarqué que des noix de chênes rouges à moitié détruites par des ravageurs avaient quand même germé et développé une radicule lorsque déposé dans mon vermicompost.

    1. New research shows that lake "stratification periods" – a seasonal separation of water into layers – will last longer in a warmer climate. These longer periods of stratification could have "far-reaching implications" for lake ecosystems, the paper says, and can drive toxic algal blooms, fish die-offs and increased methane emissions.

      Eine neue Studie ergibt, dass die globale Erhitzung die Ökosysteme von Seen weltweit schädigt. Die Periode, in der sich das Wasser in Schichten teilt, dauert länger. Dramatische Veränderungen mit Schäden für die Biodiversität lassen sich z.B. in den großen amerikanischen Seen beobachten.

    1. It is perhaps predictable that, instead of presenting a bulwark against stratification, technology outcomes have tracked society's growing inequality. A yawning chasm of disparities is playing out in our phones at the same time it has come to shape our economic and political lives.

    1. The Scottish geologist James Hutton (1726–1797), in his Theory of the Earth (1785), had studied the stratification of rocks (their arrangement in superimposed layers or strata), establishing principles which were to be the basis of archaeological excavation, as foreshadowed by Jefferson. Hutton showed that the strati-fication of rocks was due to processes still ongoing in seas, rivers, and lakes. This was the principle of “uniformitarian-ism.”

    1. John Dewey

      Dewey and Lippmann had a well-documented public feud over the role of citizens in democracy.

      Here are two articles a about their frequent debates:

      http://schugurensky.faculty.asu.edu/moments/1922lippdew.html

      https://www.infoamerica.org/teoria_articulos/lippmann_dewey.htm

      Dewey, unlike Lippmann, believed in the underlying principle that humans were capable of discernment and if they were taught the skills to correctly identify inaccurate media sources, then we would have better journalism because citizens demanded it. This theme of human agency in media is a dominant one throughout this section.

    2. "What we're experiencing," says Carr, "is, in a metaphorical sense, a reversal of the early trajectory of civilization: we are evolving from being cultivators of personal knowledge to being hunters and gatherers in the electronic data forest."

      Rheingold includes a large swath of Nicholas Carr's quotes on this page and next, which I'm not sure is helping his larger point. I happen to agree with some of Carr's arguments including this one. While I do believe its overstated, I think that his point that with there being so much content just 'out there' on the Internet, its hard to wade through the sludge for correct information, particularly if you don't have well-developed digital literacy skills.

      This is another area where media stratification comes into play. The Internet has exacerbated the issue of confirmation bias in current events, because of its democratized nature. Everyone can publish content on the web, and because of that then anyone can find a source that aligns perfectly with their beliefs and biases, whether they're grounded in fact or not.

      This is a huge contributor to the rise of the alt-right over the past year and a half. The publication of conspiracy theories, of abhorrent racist content, of confederate rage that make up alt-right circles on the Internet was a major news story during America's most recent election. Carr's point about the Internet forcing us to become 'hunters and gatherers in the electronic data forest' means that people naturally flock to sources that confirm biases they already hold.

    3. Unproductive for the goal oriented • Unhealthy for everybody • Fatal for a growing number • Addictive for some • An invitation to bad parenting • Sodally alienating • A cause for a dangerous loss of solitude

      This list of potential consequences of media-related distraction that Rheingold gives us also happen to create conditions for how ISIS recruits online, according to this Brookings article

      https://www.brookings.edu/blog/markaz/2015/11/09/how-terrorists-recruit-online-and-how-to-stop-it/

      Digital isolation is a key component in the ‘Discovery’ phase of terrorist recruitment that J.M. Berger lays out and also identified as a consequence in Rheingold’s assessment. Now of course, it’s not as if every time you get distracted from your homework and take a BuzzFeed quiz you’re a target for terrorist recruitment. It requires a concerted effort to learn more about ISIS in order for the organization to pick up on a recruit’s interest. The idea is that the more distracted you become by delving into ISIS-friendly spaces on the Internet, the more you become a potential target of ISIS recruiters. This is also an example of media stratification. The way that terrorists radicalize targets is by surrounding them with a digital community in the ‘Create micro-community’ stage of recruitment, further segregating the potential recruit into pro-ISIS circles. This experience of ISIS recruitment shows the extremes of media-triggered distraction.

    1. e development of a vast mass communications industry, concerned in the main neither with the true nor the false, but with the unreal, the more or less totally irrelevant. In a word, they failed to take into account man's almost infinite appetite for distractions.

      This quote is how Rheingold introduces one of his central themes: distraction, its evolving role in our constantly connected world, and how to deal with it productively.

      But this quote also provides an avenue to a topic that Rheingold briefly touches on later that I think is at the core of the intersection of our current political and digital discussions. That is, what is the impact of media stratification on our society? In all manner of our current dialogues, from the 2016 election, to opinions on climate change, even to the strategies of 21st century terrorist recruitment, how do we as digital citizens fight through the noise of partisan, unaccredited content to find truth? In many instances, especially in cases where someone may not possess the digital skills necessary to adequately judge the veracity of sources, we end up falling into traps of only trusting media outlets that confirm the opinions we already believe to be true. Huxley, and by extension Rheingold, points to humanity's bent towards distraction as the main source of this media stratification and increasing digital isolation into circles that continually reinforce whatever beliefs are held up as true.

    1. The conservative influence of property does not, however, depend on primogeniture or even inheritance -- features that gave property a valuable role in Burke's political system as well as in the political theories advanced by Hegel and Plato. n11 Within a single lifetime, property tends to make the property owner more risk-averse. This aversion applies both to public decisions [*291] affecting property, such as taxes, and to personal decisions that might diminish one's property, such as investment strategies and career choices. Inheritance and capital appreciation are only additional characteristics of traditional notions of property that tend to stabilize social stratification.
