Today is the "Our People-Centered Digital Future," a nonprofit,
non-partisan event, tech-for-social-good event sponsored by Constellation
Research <https://urldefense.proofpoint.com/v2/url?u=https-3A__www.constellationr.com_about&d=DwIFaQ&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=uXI5O6HThk1ULkPyaT6h2Ws3RKNKSY__GQ4DuS9UHhs&m=I791a3b1glgk8bEa_BtZQdkgj26ZwGkYqIx7mf-K-34&s=HG0AsC_QDUa_tBphrVEPHNihZmHVBa-B9LB_vgut4uo&e=>.

By March 2019, 50% of the world will be connected to the Internet, an
inflection point that marks an important moment for examining the
“unfinished work” of the Internet and discussing the community norms, human
rights, and social contracts required in the digital age.

The event recognizes both the 70th Anniversary of the Universal Declaration
of Human Rights

The event is well underway: Internet co-inventor Vint Cerf and Web inventor
Sir Tim Berners-Lee have already delivered their introductory remarks. If
you missed their talks, don't worry. You can click on the Livestream
timeline below to view them.

There are many more events to come today and into the late evening. This is
a simulcast of the YouTube feed at https://urldefense.proofpoint.com/v2/url?u=https-3A__youtu.be_S87r9Bn058s&d=DwIFaQ&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=uXI5O6HThk1ULkPyaT6h2Ws3RKNKSY__GQ4DuS9UHhs&m=I791a3b1glgk8bEa_BtZQdkgj26ZwGkYqIx7mf-K-34&s=-VJ6-Ekb77pQQ5XdzCB6SigvByC8NfKPIkjXkQk6_qg&e=> (which
does buffer occasionally), but with added AI captions and speaker names.

> In many physical networks, including neurons in the brain1,2,

> the nodes and links are physical objects that cannot intersect or overlap

> imposed to constrain the geometry of networks, which consequently affects
> how they form, evolve and function. However, these constraints are not
> included in the theoretical frameworks that are currently used to
> characterize real networks5,6,7. Most tools for laying out networks are
> variants of the force-directed layout algorithm8,9ÿÿwhich assumes
> dimensionless nodes and linksÿÿand are therefore unable to reveal the
> geometry of densely packed physical networks. Here we develop a modelling
> framework that accounts for the physical sizes of nodes and links, allowing
> us to explore how non-crossing conditions affect the geometry of a network.
> For small link thicknesses, we observe a weakly interacting
> regime in which link crossings are avoided via local link rearrangements,
> without altering the overall geometry of the layout compared to the
> force-directed layout. Once the link thickness exceeds a threshold, a
> strongly interacting regime emerges in which multiple geometric quantities,
> such as the total link length and the link curvature, scale with the link
> thickness. We show that the crossover between the two regimes is driven by
> the non-crossing condition, which allows us to derive the transition point
> analytically and show that networks with large numbers of nodes will
> ultimately exist in the strongly interacting regime. We also find that
> networks in the weakly interacting regime display a solid-like response to
> stress, whereas in the strongly interacting regime they behave in a
> gel-like fashion. Networks in the weakly interacting regime are amenable to
> 3D printing and so can be used to visualize network geometry, and the
> strongly interacting regime provides insights
> into the scaling of the sizes of densely packed mammalian brains.

> The Impact of Potential Crowd Behaviours on Emergency Evacuation
>
>     Crowd dynamics have important applications in evacuation management
> systems relevant to organizing safer large scale gatherings. For crowd
> safety, it is very important to study the evolution of potential crowd
> behaviours by simulating the crowd evacuation process. Planning crowd
> control tasks via studying the impact of crowd behavioural evolution
> towards evacuation simulation could mitigate the possibility of crowd
> disasters that may happen. During a typical emergency evacuation scenario,
> conflict among agents occurs when agents intend to move to the same
> location as a result of the interaction of agents within their nearest
> neighbours. The effect of the agent response towards their neighbourhood is
> vital in order to understand the effect of variation of crowd behaviours
> towards the whole environment. In this work, we model crowd motion subject
> to exit congestion under uncertainty conditions in a continuous space via
> computer simulations. We model best-response, risk-seeking,
> risk-averse and risk-neutral behaviours of agents via certain game theory
> notions. We perform computer simulations with heterogeneous populations in
> order to study the effect of the evolution of agent behaviours towards
> egress flow under threat conditions. Our simulation results show the
> relation between the local crowd pressure and the number of injured agents.
> We observe that when the proportion of agents in a population of
> risk-seeking agents is increased, the average crowd pressure, average local
> density and the number of injured agents get increased. Besides that, based
> on our simulation results, we can infer that crowd disaster could be
> prevented if the agent population are full of risk-averse and risk-neutral
> agents despite circumstances that lead to threat consequences.

> Quantifying the sensing power of crowd-sourced vehicle fleets
>
>     Sensors can measure air quality, traffic congestion, and other aspects
> of urban environments. The fine-grained diagnostic information they provide
> could help urban managers to monitor a city's health. Recently, a
> `drive-by' paradigm has been proposed in which sensors are deployed on
> third-party vehicles, enabling wide coverage at low cost} Research on
> drive-by sensing has mostly focused on sensor engineering, but a key
> question remains unexplored: How many vehicles would be required to
> adequately scan a city? Here, we address this question by analyzing the
> sensing power of a taxi fleet. Taxis, being numerous in cities and
> typically equipped with some sensing technology (e.g. GPS), are natural
> hosts for the sensors. Our strategy is to view drive-by sensing as a
> spreading process, in which the area of sensed terrain expands as
> sensor-equipped taxis diffuse through a city's streets. In tandem with a
> simple model for the movements of the taxis, this analogy lets us
> analytically
> determine the fraction of a city's street network sensed by a fleet of
> taxis during a day. Our results agree with taxi data obtained from nine
> major cities, and reveal that a remarkably small number of taxis can scan a
> large number of streets. This finding appears to be universal, indicating
> its applicability to cities beyond those analyzed here. Moreover, because
> taxi motions combine randomness and regularity (passengers' destinations
> being random, but the routes to them being deterministic), the spreading
> properties of taxi fleets are unusual; in stark contrast to random walks,
> the stationary densities of our taxi model obey Zipf's law, consistent with
> the empirical taxi data. Our results have direct utility for town
> councilors, smart-city designers, and other urban decision makers.
