Smartphones, Current Events and Mobile Information Behavior : Consuming, Reacting, Sharing, and Connecting through News
Smartphones and Information on Current Events provides unprecedented insights into young people’s news consumption patterns and the ecology of mobile news.Advancing our knowledge of mobile behaviour, the book also highlights the ways in which mobile news impacts the lives of the general public.Using a multi-faceted research model on mobile news consumption behaviour, Oh and Tang examined a wide spectrum of mobile news consumption activities, outlined the key characteristics of mobile news, as well as captured users’ near real-time evaluation of and emotional reactions to news stories.The book also shows that the process of using smartphones to receive, read, find, share, and store news stories has resulted in new behavioural patterns that enable people to consume news in a multifaceted way.Analyzing the extent and various methods of mobile news sharing can, Oh and Tang argue, help us understand how such exchanges reshape contemporary society.Demonstrating that mobile news consumption is now an integral part of people’s daily lives, the book clearly shows that its impact on people’s day-to-day activities, and their political and social lives, cannot be underestimated.Smartphones and Information on Current Events will be useful to scholars, students, and practitioners who are studying library and information science, journalism and media, digital communication, user behaviour, information technology, human-computer interaction, marketing, political science, psychology, and sociology.

Electromagnetic Radiation
Electromagnetic Radiation is a graduate level book on classical electrodynamics with a strong emphasis on radiation.This book is meant to quickly and efficiently introduce students to the electromagnetic radiation science essential to a practicing physicist.While a major focus is on light and its interactions, topics in radio frequency radiation, x-rays, and beyond are also treated.Special emphasis is placed on applications, with many exercises and problems.The format of the book is designed to convey the basic concepts in a mathematically rigorous manner, but with detailed derivations routinely relegated to the accompanying side notes or end of chapter "Discussions". The book is composed of four parts: Part I is a review of basic E&M (electricity and magnetism), and presents a concise review of topics covered in the subject.Part II addresses the origins of radiation in terms of time variations of charge and current densities within the source, and presents Jefimenko's field equations as derived from retarded potentials.Part III introduces special relativity and its deep connection to Maxwell's equations, together with an introduction to relativistic field theory, as well as the relativistic treatment of radiation from an arbitrarily accelerating charge.A highlight of this part is a chapter on the still partially unresolved problem of radiation reaction on an accelerating charge.Part IV treats the practical problems of electromagnetic radiation interacting with matter, with chapters on energy transport, scattering, diffraction and finally an illuminating, application-oriented treatment of fields in confined environments.

How does electromagnetic pollution occur from a radio alarm clock?
Electromagnetic pollution from a radio alarm clock occurs due to the electromagnetic radiation emitted by the clock's electronic components. The clock's circuitry and power supply generate electromagnetic fields, which can interfere with other electronic devices and potentially cause health concerns if the exposure is prolonged. Additionally, the clock's radio frequency emissions can contribute to the overall electromagnetic pollution in the surrounding environment. To minimize electromagnetic pollution, it is important to use radio alarm clocks that comply with electromagnetic compatibility standards and to keep electronic devices at a safe distance from where people sleep.

Which radio channel has the lowest WLAN electromagnetic radiation emission?
The radio channel with the lowest WLAN electromagnetic radiation emission is Channel 1. This is because it operates at the lowest frequency within the 2.4 GHz band, which results in lower electromagnetic radiation emission compared to higher frequency channels. Additionally, Channel 1 is less likely to experience interference from other devices operating in the same frequency range, making it a good choice for reducing electromagnetic radiation exposure.

What is electromagnetic induction?
Electromagnetic induction is the process by which a changing magnetic field induces an electric current in a conductor. This phenomenon was discovered by Michael Faraday in the 19th century and is the principle behind the operation of generators, transformers, and inductors. When a magnetic field around a conductor changes, it creates an electric field that causes electrons to move, generating an electric current.

What is electromagnetic pollution?
Electromagnetic pollution refers to the presence of electromagnetic fields in the environment that are caused by man-made sources such as power lines, electrical appliances, and wireless devices. These fields can have negative effects on human health and the environment, leading to concerns about potential risks such as cancer, neurological disorders, and disruptions to wildlife. Electromagnetic pollution is a growing concern as our reliance on technology increases, and efforts are being made to better understand and mitigate its impacts.

Are TV and radio stations obligated to broadcast news?
TV and radio stations are not legally obligated to broadcast news, but many choose to do so as part of their commitment to serving the public interest. In some countries, there may be regulations or licensing requirements that mandate a certain amount of news programming, but this varies by jurisdiction. Ultimately, the decision to include news in their programming is up to the individual stations and their management.

How do electromagnetic brakes work?
Electromagnetic brakes work by using the force of electromagnetism to generate braking force. When the brake is engaged, an electric current is passed through a coil, creating a magnetic field. This magnetic field then interacts with a conductive disc or drum, inducing eddy currents that create a braking force. The strength of the magnetic field and the amount of current passing through the coil can be adjusted to control the braking force, making electromagnetic brakes a versatile and efficient braking system.
