Generation IV reactor

Generation IV reactors (Gen IV) are a set of nuclear reactor designs currently being researched for commercial applications, with depending on the particular design, Technology readiness levels varying between the level requiring a demonstration, to economical competitive implementation. Most of these designs, with the exception of the BN-1200 reactor, are generally not expected to be available for commercial construction before 2030–40. Presently the majority of reactors in operation around the world are considered second generation reactor systems, as the vast majority of the first-generation systems were retired some time ago, and there are only a dozen or so Generation III reactors in operation (2014). Generation V reactors refer to reactors that are purely theoretical and are therefore not yet considered feasible in the short term, resulting in limited R&D funding.

Reactor types

Many reactor types were considered initially; however, the list was downsized to focus on the most promising technologies and those that could most likely meet the goals of the Gen IV initiative. Three systems are nominally thermal reactors and three are fast reactors. The Very High Temperature Reactor (VHTR) is also being researched for potentially providing high quality process heat for hydrogen production. The fast reactors offer the possibility of burning actinides to further reduce waste and of being able to "breed more fuel" than they consume. These systems offer significant advances in sustainability, safety and reliability, economics, proliferation resistance (depending on perspective) and physical protection.

Battlefield Hardline

Battlefield Hardline is a first-person shooter video game developed by Visceral Games in collaboration with EA DICE and published by Electronic Arts. It was released in March 2015 for Microsoft Windows, PlayStation 3, PlayStation 4, Xbox 360 and Xbox One. Unlike the previous games in the Battlefield series, Hardline focuses on crime, heist and policing elements instead of military warfare.

Upon release, the game received a mixed critical reception, with critics praising the game's multiplayer mode, voice acting and accessibility, while criticizing the game's plot, stealth and narrative.

Gameplay

The focus of the game is the "war on crime", breaking away from the military setting that hitherto characterized the series. As such, the main factions in Hardline are the police Special Response Units and criminals. Players have access to various military-grade weapons and vehicles, such as the Lenco BearCat, as well as having police equipment such as tasers and handcuffs.

Hardline also uses the Levolution mechanic from Battlefield 4. For example, in the map "Downtown" players can send a construction crane crashing into the building, ripping down debris from the central buildings in downtown, which falls down on the streets of Los Angeles. But, this time, every map features multiple Levolution events, both small and large.

Strange situation

The Strange situation is a procedure devised by Mary Ainsworth in the 1970s to observe attachment relationships between a caregiver and child. It applies to children between the age of nine and 18 months. Broadly speaking, the attachment styles were (1) secure, (2) insecure (ambivalent and avoidance). Later Mary Main and her husband Erik Hesse introduce the 3rd category, Disorganized.

Structured observation

In this procedure of the strange situation the child is observed playing for 20 minutes while caregivers and strangers enter and leave the room, recreating the flow of the familiar and unfamiliar presence in most children's lives. The situation varies in stressfulness and the child's responses are observed. The child experiences the following situations:
