Unreferenced date January 2007 Production blocking is a common problem in brainstorming groups. It is a tendency for one individual to block or inhibit other people during a group discussion. For example, if six people are in a group and one person is talking about his or her idea, then the other five people are blocked and less able to provide their own creative input. They may not have time to think of an idea, or they may be distracted or forget about their idea before they have an opportunity to share it. Production blocking becomes more of a problem as the size of the group increases. Production blocking is not the same thing as social loafing because it is an attentional or cognitive barrier, not a motivational one.

Unreferenced date January 2007 Blocking is an animation technique in which key Pose computer vision poses are created to establish timing and placement of characters and Theatrical property prop s in a given scene or shot. Blocking is most commonly used in 3D computer graphics 3D computer animation. Blocking is often the first step in the pose to pose style of animating, as opposed to the straight ahead style of animation though blocking sometimes plays a role in straight ahead as well. Blocking poses are not necessarily exclusively keyframe s. Blocked in poses may also include important in betweens, extremes, and breakdowns necessary to establishing the flow and timing of a particular shot. In 3D, the animation curves of a blocked shot are often created using stepped or square tangencies, which provides no interpolation between animation poses. This allows the animator to see the poses of the animation without any strange and or unintentional automatic interpolation. While this is sometimes problematic due to gimbal lock , seeing the poses in this way allows the animator to adjust the timing of an animation quickly, without the distraction of the software s automatic interpolation.

Blocking or denial is a term used in theater theatrical improvisation to describe an act of not accepting the world that has been set up, or of refusing to develop an action that another performer has offered . This is the opposite of Yes, And... In general, blocking prevents improvisers from developing stories since it tends to reduce the scene to a battle for dominance between the performers, each pulling the fiction in a different direction this is different from the interplay involved in dramatic Conflict narrative conflict , in which the characters pull in different directions. Improvisation coaches can usually tell the difference between defensive blocking initiated by nervous or inexperienced improvisers and the more playful or constructive blocking that more comfortable or experienced performers may introduce. Since we enjoy watching someone being thwarted, blocking often provokes laughter from the audience. For this reason, when improvisation is performed in comedy clubs, as opposed to theatres, blocking may become the norm it is seen rarely in theatrical improvisation companies.

Unreferenced date December 2009 Orphan date February 2009 Image KitchenBlocking.JPG thumb 350px right Blocking intended for cabinets In construction blocking refers to pieces of wood or other material that run between wall stud s in order to provide support and attachment sites for mounted hardware such as cabinets , shelving, vanity tops without a cabinet underneath, or bathroom towel bars. Construction Traditionally 2x4 or 2x6 boards are cut to size and nailed between studs. Since studs are usually spaced 16 or 24 inches apart, scrap pieces of dimensional lumber can often be used. For maximum utility, rows of blocking should be set at a predetermined height and installed flush with the interior plane of the wall. Individual boards should be secured with at least one nail or screw through each stud. Blocking is the act of installing solid pieces of wood or blocks to a deck, bulkhead, or overhead in such manner that these pieces bear directly against the cargo to prevent movement of the cargo in the horizontal plane. Purpose Properly installed blocking is easier to find and use for attaching wall hardware than studs alone. Once drywall , or any other material, covers the wall it can be difficult to find 2x4 studs for attachment, and the position of nails and screws must be adjusted to stud location. Thus, if blocking is installed at a uniform and predetermined height, attachment sites can be found without using a stud finder , and the blocking can be utilized anywhere along a wall at that height. This is particularly useful for installing upper cabinets in kitchens or bathrooms as they tend to be fairly heavy and finding appropriate studs for installation can be difficult.

Refimprove date June 2008 Blocking occurs when a subroutine does not return until it either completes its task or fails with an error or exception computing exception . A process that is blocked is one that waits for some event computing event , such as a resource computer science resource becoming available or the completion of an I O operation. ref harv Stallings 2004 ref In a Computer multitasking multitasking computer system, individual task computing task s, or thread of execution threads of execution , must share the resources of the system. These resources might be the CPU network memory disk When one task is using a resource, it is generally not possible, or desirable, for another task to access it. The techniques of mutual exclusion are used to prevent this concurrent use. When the other task is blocked, it is unable to execute until the first task has finished using the shared resource. Programming language s and scheduling algorithm s are designed to minimize this blocking, and to prevent the case of deadlock , where two or more tasks are blocked, waiting for a resource that the other holds. In a hypothetical two Process states state running and not running model, processes would go onto the ready queue before being dispatched for execution. In the absence of a blocked state, if priority is measured by holdup time, blocked processes would erroneously get scheduled despite having nothing to operate on. This is undesirable due to inefficient processor usage. Hence the efficient use of resources makes a case for a blocked queue in which processes line up until the event dependency resolves. Once the event fires, the process is advanced from blocked state to an imminent one, such as Process states Ready runnable .

Cross blocking is the method that a Slalom skiing slalom ski racer uses to draw his body s center of gravity closer to the fall line and increase his speed. This is done by diverting gates with his outer hand or arm normally protected from the impact by a pole guard .

Thus they hit the pole modern ones are designed to easily bend with their outside hand to move it out of the way. Usually, the skier s shin guard will then push the gate down further.

Expert subject statistics date November 2008 In the statistical theory of the design of experiments , blocking is the arranging of experimental unit s in groups blocks that are similar to one another. For example, an experiment is designed to test a new drug on patients. There are two levels of the treatment, drug , and placebo , administered to male and female patients in a double blind trial. The sex of the patient is a blocking factor accounting for treatment variability between males and females . This reduces sources of variability and thus leads to greater precision. Suppose we have invented a process intended to make the soles of shoes last longer, and we plan to conduct a field trial. Given a group of n volunteers, one possible design would be to give n 2 of them shoes with the new soles and n 2 of them shoes with the ordinary soles, randomization randomizing the assignment of the two kinds of soles. This type of experiment is a completely randomized design . We ask both groups to use their shoes for a period of time, and then measure the degree of wear of the soles. This is a workable experimental design, but purely from the point of view of statistical accuracy ignoring any other factors , a better design would be to give each person one regular sole and one new sole, randomly assigning the two types to the left and right shoe of each volunteer. Such a design is called a randomized complete block design . This design will be more sensitive than the first, because each person is acting as their own control and thus the control group is more closely matched to the treatment group .

The act of blocking the plate accounts for most of the physical contact in baseball. By the rules of baseball, a runner has the right to an Obstruction baseball unobstructed path to a Base baseball base . However, this right is not granted if the fielder guarding the base possesses the ball or is in the process of catching the ball. The fielders guarding first through third base are unlikely to risk physical harm and will generally place themselves out of the path of the runner. The catcher guarding home plate , however, wears padding and a face mask and will frequently place his body as an obstacle between the runner and home plate. Since the runner does not have to worry about remaining on home plate, only tagging it, he will run at full speed in an effort to reach the final base. The speed of the runner combined with the fact that the catcher still has to tag him unless the bases are loaded and the force play at home is still available makes for a dramatic play. Technique Any time there is a close play at home plate, meaning the ball and runner reach the plate at the same time, the catcher squats in front of the plate to block a clear path. Unless he is willing to be tagged out, the runner who is faced with a blocked plate has two choices. He can Attempt to slide baseball slide around the catcher and avoid being tagged, or, Collide with the catcher with such force that the catcher has no chance of keeping possession of the ball.
