O Brave New World: The Dark Side of Cyberspace
This article focuses on some of the negative aspects of cyberspace andcyberculture. First, it offers an examination of the impact of our use ofsocial media, and Facebook in particular, on our psyches, pointing out thatusers of social media can be thought of as audiences. These audiencesand information about them can be sold to marketers and advertisers.Next, it offers a case study of a widespre...
متن کاملMinimal dark matter in type III seesaw
We explore the possibility of a new dark matter candidate in the supersymmetric type III seesaw mechanism where a neutral scalar component of the Y= 0 triplet can be the lightest supersymmetric particle. Its thermal abundance can be in the right range if non-standard cosmology such as kination domination is assumed. The enhanced cross-section of the dark matter annihilation to WW can leave dete...
متن کاملThe dark side of cosmology: dark matter and dark energy.
A simple model with only six parameters (the age of the universe, the density of atoms, the density of matter, the amplitude of the initial fluctuations, the scale dependence of this amplitude, and the epoch of first star formation) fits all of our cosmological data . Although simple, this standard model is strange. The model implies that most of the matter in our Galaxy is in the form of "dark...
متن کاملThe Dark Side of Leadership
44 / n recent years, business leaders have gained great popularity: Lee Iaccoca and Steven Jobs, for example, have stepped into the limelight as agents of change and entrepreneurship. But though we tend to think of the positive outcomes associated with leaders, certain risks or liabilities are also entailed. The very behaviors that distinguish leaders from managers also have the potential to pr...
متن کاملMulticomponent Dark Matter in Radiative Seesaw Models
We discuss radiative seesaw models, in which an exact Z2 × Z′ 2 symmetry is imposed. Due to the exact Z2 × Z′ 2 symmetry, neutrino masses are generated at a two-loop level and at least two extra stable electrically neutral particles are predicted. We consider two models: one has a multi-component dark matter system and the other one has a dark radiation in addition to a dark matter. In the mult...
