Jane Jacobs's Theories on Urban Planning-and Democracy in America - The Atlantic - 0 views

  • Urban life was Jacobs’s great subject. But her great theme was the fragility of democracy—how difficult it is to maintain, how easily it can crumble. A city offered the perfect laboratory in which to study democracy’s intricate, interconnected gears and ballistics. “When we deal with cities,” she wrote in The Death and Life of Great American Cities (1961), “we are dealing with life at its most complex and intense.” When cities succeed, they represent the purest manifestation of democratic ideals: “Cities have the capability of providing something for everybody, only because, and only when, they are created by everybody.” When cities fail, they fail for the same reasons democracies fail: corruption, tyranny, homogenization, overspecialization, cultural drift and atrophy.
  • I was encouraged to believe that simple conformity results in stagnation for a society, and that American progress has been largely owing to the opportunity for experimentation, the leeway given initiative, and to a gusto and a freedom for chewing over odd ideas. I was taught that the American’s right to be a free individual, not at the mercy of the state, was hard-won and that its price was eternal vigilance, that I too would have to be vigilant.
  • Her 1,500-word speech, a version of which appears in Vital Little Plans, became the basis for The Death and Life of Great American Cities. Her main argument was Kirk’s: Small neighborhood stores, ignored by the planners in their grim demolition derby, were essential social hubs. She added that sidewalks, stoops, laundries, and mailbox areas were also indispensable centers of community activity, and that sterile, vacant outdoor space served nobody. “The least we can do,” she said, “is to respect—in the deepest sense—strips of chaos that have a weird wisdom of their own.”

  • Reduced to a word, Jacobs’s argument is that a city, or neighborhood, or block, cannot succeed without diversity: diversity of residential and commercial use, racial and socioeconomic diversity, diversity of governing bodies (from local wards to state agencies), diverse modes of transportation, diversity of public and private institutional support, diversity of architectural style. Great numbers of people concentrated in relatively small areas should not be considered a health or safety hazard; they are the foundation of a healthy community. Dense, varied populations are “desirable,” Jacobs wrote,
  • Madison argued that as you increase the “variety of parties and interests” contained within a republic, “you make it less probable that a majority of the whole will have a common motive to invade the rights of other citizens.”
  • “We need all kinds of diversity,” Jacobs concluded in Death and Life, “so the people of cities can sustain (and further develop) their society and civilization.”
  • In her comparative study of fallen empires, Jacobs identifies common early indicators of decline: “cultural xenophobia,” “self-imposed isolation,” and “a shift from faith in logos, reason, with its future-oriented spirit … to mythos, meaning conservatism that looks backwards to fundamentalist beliefs for guidance and a worldview.” She warns of the profligate use of plausible denial in American politics, the idea that “a presentable image makes substance immaterial,” allowing political campaigns “to construct new reality.” She finds further evidence of our hardening cultural sclerosis in the rise of the prison-industrial complex, the prioritization of credentials over critical thinking in the educational system, low voter turnout, and the reluctance to develop renewable forms of energy in the face of global ecological collapse.
  • In the foreword to the 1992 Modern Library edition of Death and Life, Jacobs likens cities to natural ecosystems. “Both types of ecosystems,” she writes, “require much diversity to sustain themselves … and because of their complex interdependencies of components, both kinds of ecosystems are vulnerable and fragile, easily disrupted or destroyed.”

The Con of Diversity - 0 views

  •  
    "Harvard got what it wanted. Mediocrity in the name of diversity. It was a classic example of how the white power structure plays people of color. It decides whom to promote and whom to silence. When then-Maj. Colin Powell helped cover up the 1968 massacre of some 500 civilians at My Lai in Vietnam he was assured a glittering career in the Army. When Barack Obama proved obedient to the Chicago political machine, Wall Street and the Democratic Party establishment he was promoted to the U.S. Senate and the presidency. Diversity in the hands of the white power elites-political and corporate-is an advertising gimmick. A new face, a brand, gets pushed out front, accompanied by the lavish financial rewards that come with serving the white power structure, as long as the game is played. There is no shortage of women (Hillary Clinton, Nancy Pelosi and Donna Brazile), Latinos (Tom Perez and Marco Rubio) or blacks (Vernon Jordan, Clarence Thomas and Ben Carson) who sell their souls for a taste of power."

For better AI, diversify the people building it - 0 views

  • Lyons announced the Partnership on AI’s first three working groups, which are dedicated to fair, transparent, and accountable AI; safety-critical AI; and AI, labor, and the economy. Each group will have a for-profit and nonprofit chair and aim to share its results as widely as possible. Lyons says these groups will be like a “union of concerned scientists.” “A big part of this is on us to really achieve inclusivity,” she says. Tess Posner, the executive director of AI4ALL, a nonprofit that runs summer programs teaching AI to students from underrepresented groups, showed why training a diverse group for the next generation of AI workers is essential. Currently, only 13 percent of AI companies have female CEOs, and less than 3 percent of tenure-track engineering faculty in the US are black. Yet an inclusive workforce may have more ideas and can spot problems with systems before they happen, and diversity can improve the bottom line. Posner pointed out a recent Intel report saying diversity could add $500 billion to the US economy.
  • “It’s good for business,” she says. These weren’t the first presentations at EmTech Digital by women with ideas on fixing AI. On Monday, Microsoft researcher Timnit Gebru presented examples of bias in current AI systems, and earlier on Tuesday Fast.ai cofounder Rachel Thomas talked about her company’s free deep-learning course and its effort to diversify the overall AI workforce. Even with the current problems achieving diversity, there are more women and people of color that could be brou

Diverse interactions and ecosystem engineering can stabilize community assembly | Natur... - 0 views

  •  
    The complexity of an ecological community can be distilled into a network, where diverse interactions connect species in a web of dependencies. Species interact directly with each other and indirectly through environmental effects, however to our knowledge the role of these ecosystem engineers has not been considered in ecological network models. Here we explore the dynamics of ecosystem assembly, where species colonization and extinction depends on the constraints imposed by trophic, service, and engineering dependencies. We show that our assembly model reproduces many key features of ecological systems, such as the role of generalists during assembly, realistic maximum trophic levels, and increased nestedness with mutualistic interactions. We find that ecosystem engineering has large and nonlinear effects on extinction rates. While small numbers of engineers reduce stability by increasing primary extinctions, larger numbers of engineers increase stability by reducing primary extinctions and extinction cascade magnitude. Our results suggest that ecological engineers may enhance community diversity while increasing persistence by facilitating colonization and limiting competitive exclusion.

Zoonotic host diversity increases in human-dominated ecosystems | Nature - 0 views

  •  
    Land use change-for example, the conversion of natural habitats to agricultural or urban ecosystems-is widely recognized to influence the risk and emergence of zoonotic disease in humans1,2. However, whether such changes in risk are underpinned by predictable ecological changes remains unclear. It has been suggested that habitat disturbance might cause predictable changes in the local diversity and taxonomic composition of potential reservoir hosts, owing to systematic, trait-mediated differences in species resilience to human pressures3,4. Here we analyse 6,801 ecological assemblages and 376 host species worldwide, controlling for research effort, and show that land use has global and systematic effects on local zoonotic host communities. Known wildlife hosts of human-shared pathogens and parasites overall comprise a greater proportion of local species richness (18-72% higher) and total abundance (21-144% higher) in sites under substantial human use (secondary, agricultural and urban ecosystems) compared with nearby undisturbed habitats. The magnitude of this effect varies taxonomically and is strongest for rodent, bat and passerine bird zoonotic host species, which may be one factor that underpins the global importance of these taxa as zoonotic reservoirs. We further show that mammal species that harbour more pathogens overall (either human-shared or non-human-shared) are more likely to occur in human-managed ecosystems, suggesting that these trends may be mediated by ecological or life-history traits that influence both host status and tolerance to human disturbance5,6. Our results suggest that global changes in the mode and the intensity of land use are creating expanding hazardous interfaces between people, livestock and wildlife reservoirs of zoonotic disease.

The Soil Talks Back - 0 views

    ]. "The narrow strip of soil around the plant's root teems with millions of microorganisms, making it one of the most complex ecosystems on earth. To determine whether the composition of this "root microbiome" triggers changes within the plant, postdoctoral fellow Dr. Elisa Korenblum and other members of a team headed by Prof. Asaph Aharoni of Weizmann's Plant and Environmental Sciences Department, created a hydroponic set-up in which they split the roots of tomato seedlings in two. In a series of experiments, the researchers placed one side of the split roots in vials, progressively diluting the soil suspensions several times. Each dilution altered the soil's microbial composition and reduced the diversity within the microbial community, so that the different suspensions ended up containing root microbiomes with high, medium and low diversity levels. The other side of the roots was submerged in a vial with a clean, soil-free solution. If the soil microbes communicate with the plant, one would expect to detect signs of their messages on both sides of the root system. That was exactly what the scientists found…. 'Our ultimate goal is to decipher the chemical language - one could call it 'Plantish' - used by plants and the soil to interact with one another,' Korenblum

The Archdruid Report - 0 views

    "It's time to consider, I suggest, a renewal of the traditions of American federalism: a systematic devolution of power from the overinflated federal government to the states, and from the states to the people. It's time for people in Massachusetts to accept that they're never going to be able to force people in Oklahoma to conform to their notions of moral goodness, and for the people of Oklahoma to accept the same thing about the people of Massachusetts; furthermore, it's time for government at all levels to give up trying to impose cultural uniformity on the lively diversity of our republic's many nations, and settle for their proper role of ensuring equal protection under the laws, and those other benefits that governments, by their nature, are best suited to provide for their citizens.
