Staffing: A Vital Function in Organizational Success

Definition and Importance

Staffing is the process of acquiring, developing, and maintaining a workforce that meets the needs of an organization. It involves identifying and recruiting qualified individuals, selecting the best candidates, and providing them with the necessary training and development to perform their jobs effectively.

Staffing is a critical function for any organization because it directly impacts its ability to achieve its goals. A well-staffed organization has the right people in the right positions, with the skills and knowledge necessary to contribute to the organization's success.

Features of Staffing

1. Universal Function: Staffing is the responsibility of every manager, regardless

Normal shock wave leads - to total turbulence behind shock wave

How to calculate drag coefficient - ratio between drag pressure to dynamic pressure

Turbulence caused by wing vortices absorb - increased induced drag

Induced drag reduced - higher aspect ratio

Lift augmentation devices - increase lift at slow speed (takeoff landing)

Wing fences used to reduce - effects of span-wise flow

Directional stability - sweepback of wing and vertical tail

Control surfaces give longitudinal control - elevators

Acceleration - change of velocity divided by time during which change occurs

Resistance of skin friction of air passes - parasite drag

Lift produced by an airfoil is resultant - relative wind

Types of stability - dynamic and static

Generally center of pressure

Aerodynamics

The study of the properties of moving air, and especially of the interaction between the air and solid bodies moving through it.

Airfoil

A structure with curved surfaces designed to give the most favorable ratio of lift to drag in flight, used as the basic form of the wings, fins, and horizontal stabilizer of most aircraft.

Angle of Attack

Is the angle between the oncoming air or relative wind and a reference line on the airplane or wing.

Angle of Incidence

The acute angle the wing chord makes with the longitudinal axis of the aircraft is called the angle of incidence, or the angle of wing setting. A Chord Line is a line depicting the chord which extends forward of the leading edge.

Boundary Layer

On an aircraft wing the boundary layer... Continue reading "Understanding Aerodynamics and Aircraft Flight" »

1 Inside The larynx there are two flaps of muscle which are called the vocal or folds

vocal cords.

2 The space Between them is known as the glottis.

-wide Glottis /p/ /f/ /s/

- narrow Glottis /h/

-vocal Folds’ vibration

-tigtitly Closed ?  -when we cough

Producing sounds              air---stop the flow of air—move to Articulators—produce release

3 When they Are tightly closed they can be made to produce a glottal stop.

4 When they Are close together and air is passed between them, the resulting vibration is Called voicing or phonation.

5 Three Variables in this vibration that are relevant in speech are: intensity: high/low levels, frequency amount Vibration/regularity, quality whispering/breathy.
