    1. Many individuals are sentenced without any due process of the law. 

      reasons why the mass incarceration is a thing and why many people are incarcerated in the us alone.

    1. Zero Mass Water Climate crisis has led us to water crises in some places on the Earth. Since humans cannot survive without water, the water crisis is not something we can take lightly. Zero Mass Water offers a solution to transform thin air into potable water. https://allsustainablesolutions.com/zero-mass-water-sustainable-water-production/

    1. We have to recognize that prior to Web 2.0 and social media, “the media” often connoted “mass media,” broadcast from the few to the many.

      One of the issues we're seeing is that mass media still exists within platforms like Facebook and Google, the problem is that the "gatekeepers" now have vastly different structure and motivation. The ostensible gatekeeper now is an algorithm that puts all it' emphasis on velocity, stickiness, shareability, and the power of anger (which pushes clicks, likes, and shares). Thus the edge content is distributed far and wide rather than the "richest" and most valuable content that a democracy relies on for survival. Mass media is still with us, we've just lost the value of the helmsperson controlling the direction of the rudder.

    1. What happens to matter when it undergoes chemical changes? The Law of conservation of mass says that "Atoms are neither created, nor distroyed, during any chemical reaction." Thus, the same collection of atoms is present after a reaction as before the reaction. The changes that occur during a reaction just involve the rearrangement of atoms.

    1. Edward Snowden disclosed in 2013 that the US government's Upstream program was collecting data people reading Wikipedia articles. This revelation had significant impact the self-censorship of the readers, as shown by the fact that there were substantially fewer views for articles related to terrorism and security.[12] The court case Wikimedia Foundation v. NSA has since followed.
    1. Google's move to release location data highlights concerns around privacy. According to Mark Skilton, director of the Artificial Intelligence Innovation Network at Warwick Business School in the UK, Google's decision to use public data "raises a key conflict between the need for mass surveillance to effectively combat the spread of coronavirus and the issues of confidentiality, privacy, and consent concerning any data obtained."

    1. Liberal and Conservative Representations of the Good Society: A (Social) Structural Topic Modeling Approach

      I chose this article, because it is timely, relevant, easy-to-follow (because it is intuitive), and innovative (using data sources, Twitter, and an innovative method, textual analysis). I hope you enjoy the reading. Please follow my annotations (comments + questions) and respond to the questions I pose. Try to answer them in your own words.

    1. One possibility is the American preoccupation with fame. Studies have found that Americans are more interested in fame than people of other nationalities are. A 2007 Pew Research survey of 18- to 25-year-olds found that about half said that getting famous was a top priority for their peers. Television shows increasingly promote fame as a value, research has found, and pop lyrics are becoming more narcissistic. A 2010 review of research studies found that modern college students display less empathy than students of the late 1970s. These studies fit a general pattern of research showing that narcissism is on the rise. Simultaneously, Lankford said, the line between being famous and infamous is blurring. Scientists looked at the covers of People magazine issues dating from 1974 to 1998, and found that cover stars were increasingly featured for bad behavior — cheating, arrests, crime — rather than good acts (though there was a slight shift toward positivity after the Sept. 11 terrorist attacks), according to their 2005 report.

    1. Let Σ0be a compact strictly convex hypersurface inRn,Xbe the position vector ofa point on Σ0, and letNbe the unit outward normal of Σ0atX. Let Σrbe the convexhypersurface described byY=X+rN, withr≥0. The Euclidean space outside Σ0canbe represented by(Σ0×(0,∞),dr2+gr)wheregris the induced metric on Σr. Consider the following initial value problem(2.1)2H0∂u∂r= 2u2∆ru+ (u−u3)Rron Σ0×[0,∞)u(x,0) =u0(x)whereu0(x)>0 is a smooth function on Σ0,H0andRrare the mean curvature and scalarcurvature of Σrrespectively, and ∆ris the Laplacian operator on Σr.

      Note que de agora em diante o autor se detém a estudar esse caso particular, onde estão inteiramente determinadas as geometrias intrínseca e extrínseca das folhas do semi cilindro, obtido folheando-se pelas paralelas o exterior da hipersuperfície estritamente convexa dada a priori.

    2. Given a functionRonN, we want to find the equation forusuch that(1.2)ds2=u2dρ2+gρhas scalar curvatureR.

      O papel da aplicação \( u: N \longrightarrow \mathbb{R} \) é distorcer as fibras do semi cilindro \( N \), por dilatações e torções, deixando a geometria intrínseca das folhas invariante, de tal forma que o resultado seja um semi cilindro com a curvatura escalar prescrita \( \mathcal{R} \).

    3. Let Σ be a smooth compact manifold without boundary with dimensionn−1 and letN= [a,∞)×Σ equipped with a Riemannian metric of the form(1.1)ds20=dρ2+gρfor a point (ρ,x)∈N. Heregρis the induced metric on Σρwhich is the level surfaceρ=constant

      Isso significa que a construção a seguir é feita a partir de um semi cilindro em que a geometria das folhas é dada a priori.

      Esse artigo não trata da construção desse semi cilindro inicial.

    1. massmediarefers to those means of transmission

      When I ask students to post on Youth Voices, I'm asking them to participate in mass media. It's a big jump for some who do very little by friend-to-friend communication.

    1. Patrick Ball—a data scientist and the director of research at the Human Rights Data Analysis Group—who has previously given expert testimony before war crimes tribunals, described the NSA's methods as "ridiculously optimistic" and "completely bullshit." A flaw in how the NSA trains SKYNET's machine learning algorithm to analyse cellular metadata, Ball told Ars, makes the results scientifically unsound.

    1. I am really interested in the possibilities, the prospect of bipartisan legislation around the criminal justice system -- something that I think directly speaks to some of the themes I mentioned on Friday. And we’ve seen some really interesting leadership from some unlikely Republican legislators very sincerely concerned about making progress there.
