Life support

Life support refers to the treatments and techniques performed in an emergency in order to support life after the failure of one or more vital organs. Healthcare providers and emergency medical technicians are generally certified to perform basic and advanced life support procedures; however, basic life support is sometimes provided at the scene of an emergency by family members or bystanders before emergency services arrive. In the case of cardiac injuries, cardiopulmonary resuscitation is initiated by bystanders or family members 25% of the time. Basic life support techniques, such as performing CPR on a victim of cardiac arrest, can double or even triple that patient's chance of survival. Other types of basic life support include relief from choking (which can be done by using the Heimlich maneuver), staunching of bleeding by direct compression and elevation above the heart (and if necessary, pressure on arterial pressure points and the use of a manufactured or improvised tourniquet), first aid, and the use of an automated external defibrillator.

Sympathy

Sympathy (from the Greek words syn "together" and pathos "feeling" which means "fellow-feeling") is the perception, understanding, and reaction to the distress or need of another human being. This empathic concern is driven by a switch in viewpoint, from a personal perspective to the perspective of another group or individual who is in need. Empathy and sympathy are often used interchangeably. Sympathy is a feeling, but the two terms have distinct origins and meanings. Merriam Webster defines empathy as "the feeling that you understand and share another person's experiences and emotions : the ability to share someone else's feelings." Their definition of sympathy is "the feeling that you care about and are sorry about someone else's trouble, grief, misfortune, etc. : a feeling of support for something : a state in which different people share the same interests, opinions, goals, etc." See professor Paul Bloom on empathy.

Causes

In order to get an experience of sympathy there are specific conditions that need to occur. These include: attention to a subject, believing that a person/group is in a state of need, and the specific characteristics of a given situation. An individual must first give his or her attention to a person/group. Distractions severely limit the ability to produce strong affective responses. Without distractions, people are able to attend to and respond to a variety of emotional subjects and experiences. Attention facilitates the experience of sympathy, and without giving undivided attention to many situations sympathy cannot be experienced.

Support and resistance

In technical analysis, support and resistance is a concept that the movement of the price of a security will tend to stop and reverse at certain predetermined price levels. These levels are denoted by multiple touches of price without a breakthrough of the level.

Support versus resistance

A support level is a level where the price tends to find support as it falls. This means the price is more likely to "bounce" off this level rather than break through it. However, once the price has breached this level, by an amount exceeding some noise, it is likely to continue falling until meeting another support level.

A resistance level is the opposite of a support level. It is where the price tends to find resistance as it rises. This means the price is more likely to "bounce" off this level rather than break through it. However, once the price has breached this level, by an amount exceeding some noise, it is likely to continue rising until meeting another resistance level.

Organ (music)

In music, the organ (from Greek ὄργανον organon, "organ, instrument, tool") is a keyboard instrument of one or more divisions, each played with its own keyboard, played either with the hands or with the feet. The organ is a relatively old musical instrument, dating from the time of Ctesibius of Alexandria, who is credited with inventing the water organ. It was played throughout the Greek and Roman world, particularly during races and games. During the early medieval period it spread from the Byzantine Empire, where it continued to be used in secular and imperial court music, to Western Europe, where it gradually assumed a prominent place in the liturgy of the Catholic Church. Subsequently it re-emerged as a secular and recital instrument.

Overview

Pipe organs use wind moving through pipes to produce sounds. Since the 16th century, pipe organs have used various materials for pipes, which can vary widely in timbre and volume. The pipes are divided into ranks and controlled by the use of hand stops and combination pistons. Although the keyboard is not expressive as on a piano and does not affect dynamics (pressing a key only turns the sound on or off), some divisions may be enclosed in a swell box, allowing the dynamics to be controlled by shutters. Some organs are totally enclosed, meaning that all the divisions can be controlled by one set of shutters. Some special registers with free reed pipes are expressive. These instruments vary greatly in size, ranging from a cubic yard to a height reaching five floors, and are built in churches, synagogues, concert halls, and homes. Small organs are called "positive" (easily placed in different locations) or "portative" (small enough to carry while playing). Increasingly hybrid organs are appearing in which pipes are augmented with electronic additions. Great economies of space and cost are possible especially when the lowest (and largest) of the pipes can be replaced.
