The five themes of geography are location, place, human-environment interaction, movement, and region. These were defined in by the National Council for Geographic Education and the Association of American Geographers to facilitate and organize the teaching of geography in the K classroom. While the five themes have since been supplanted by the National Geography Standardsthey still provide an effective means or organizing geography instruction.
Most geographic studies begin by learning the location of places. Location can be absolute or relative. Place describes the human and physical characteristics of a location. This theme considers how humans adapt to and modify the environment. Humans shape the landscape through their interaction with the land, which has both positive and negative effects on the environment.
As an example of the human-environment interactionthink about how people living in cold climates have often mined coal or drilled for natural gas in order to heat their homes. Another example would be the massive landfill projects in Boston conducted in the 18th and 19th centuries to expand habitable areas and improve transportation. Humans move—a lot!
In addition, ideas, fads, goods, resources, and communication all travel distances. This theme studies movement and migration across the planet. Regions divide the world into manageable units for geographic study. Regions have some sort of characteristic that unifies the area and can be formal, functional, or vernacular.

Following high-profile police killings of black men in Baton Rouge and Minneapolis, fatal attacks on officers by anti-police gunmen — and more recently protests in North Carolina after the police shooting of Keith Scott, a black man — the United States is being forced to confront its deep-rooted problems with race and inequality.
A strong narrative is emerging from these tragedies of racially motivated targeting of black Americans by the police force. It is backed up by a new report on the city of Baltimore by the Department of Justice, which has found that black residents of low-income neighbourhoods are more likely to be stopped and searched by police officers, even if white residents are statistically more likely to be caught carrying guns and drugs.
In the background, a campaign called Black Lives Matter celebrated its third anniversary. The movement, perhaps best known by its hashtag BlackLivesMatter, grew in protest against police killings of black people in the United States.Mx sticker kits
It has now crossed the Atlantic, with events and rallies held in the United Kingdom. The movement was born inafter the man who shot and killed an unarmed black teenager, Trayvon Martin, was cleared of his murder. I love you. I love us. Our lives matter. The formal organization that sprung from the protests started with the goal of highlighting the disproportionate number of incidences in which a police officer killed a member of the black community.
But it soon gained international recognition, after the death of Michael Brown in Missouri a year later. It has developed to include the issues of black women and LGBT communities, undocumented black people and black people with disabilities. According to this article in the Washington Post1, people have been shot and killed by on-duty police officers since the beginning of A cursory glance at the numbers reveals nothing to indicate racial bias: of the victims were white and were black were of another race.
After adjusting for population percentage, this is the picture: black Americans are two and a half times more likely than white Americans to be shot and killed by police officers. However, we have to count for distortion of the data, for various reasons. Firstly, it is collected through the voluntary collaboration of police departments with the Federal Bureau of Investigation, so not the full picture. Additionally, police-involved shootings that are under investigation are only counted once the investigation has concluded, so many recent incidents are not being counted.
The All Lives Matter campaign, for instance, is one among several groups that have sprung up to argue that every human life, not just those of black people, should be given equal consideration. In the wake of the mass shooting of five police officers in Dallas in July, a new campaign has taken root.Brownian motionalso called Brownian movementany of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations.Online harmonizer vocal free
It was named for the Scottish botanist Robert Brownthe first to study such fluctuations If a number of particles subject to Brownian motion are present in a given medium and there is no preferred direction for the random oscillations, then over a period of time the particles will tend to be spread evenly throughout the medium.
The physical process in which a substance tends to spread steadily from regions of high concentration to regions of lower concentration is called diffusion. Diffusion can therefore be considered a macroscopic manifestation of Brownian motion on the microscopic level.
Thus, it is possible to study diffusion by simulating the motion of a Brownian particle and computing its average behaviour. Other researchers had noticed this phenomenon earlier, but Brown was the first to study it. Initially he believed that such motion was a vital activity peculiar to the male sex cells of plants, but he then checked to see if the pollen of plants dead for over a century showed the same movement.
Finally, in inarguable support of the nonliving nature of the phenomenon, he demonstrated it in fluid-filled vesicles in rock from the Great Sphinx. Early explanations attributed the motion to thermal convection currents in the fluid. When observation showed that nearby particles exhibited totally uncorrelated activity, however, this simple explanation was abandoned.
By the s theoretical physicists had become interested in Brownian motion and were searching for a consistent explanation of its various characteristics: a given particle appeared equally likely to move in any direction; further motion seemed totally unrelated to past motion; and the motion never stopped.12 Principles of Animation (Official Full Series)
An experiment in which a suspension was sealed in glass for a year showed that the Brownian motion persisted. More systematic investigation in determined that small particle size and low viscosity of the surrounding fluid resulted in faster motion. According to the theory, the temperature of a substance is proportional to the average kinetic energy with which the molecules of the substance are moving or vibrating. It was natural to guess that somehow this motion might be imparted to larger particles that could be observed under the microscope; if true, this would be the first directly observable effect that would corroborate the kinetic theory.
This line of reasoning led the German physicist Albert Einstein in to produce his quantitative theory of Brownian motion. Einstein wrote later that his major aim was to find facts that would guarantee as much as possible the existence of atoms of definite size. In the midst of this work, he discovered that according to atomic theory there would have to be an observable movement of suspended microscopic particles. Einstein did not realize that observations concerning the Brownian motion were already long familiar.
Reasoning on the basis of statistical mechanicshe showed that for such a microscopic particle the random difference between the pressure of molecular bombardment on two opposite sides would cause it to constantly wobble back and forth. A smaller particle, a less viscous fluid, and a higher temperature would each increase the amount of motion one could expect to observe.Nordhavn 96 for sale
The equation for this relationship is. The introduction of the ultramicroscope in aided quantitative studies by making visible small colloidal particles whose greater activity could be measured more easily. Several important measurements of this kind were made from to His work established the physical theory of Brownian motion and ended the skepticism about the existence of atoms and molecules as actual physical entities.

However, the purpose of this language is not to confuse, but rather to increase precision and reduce medical errors. Or is it at the base of the hand?
Is it on the palm-side or back-side? By using precise anatomical terminology, we eliminate ambiguity. Anatomical terms derive from ancient Greek and Latin words. Because these languages are no longer used in everyday conversation, the meaning of their words does not change.
Anatomical terms are made up of roots, prefixes, and suffixes. The root of a term often refers to an organ, tissue, or condition, whereas the prefix or suffix often describes the root. To further increase precision, anatomists standardize the way in which they view the body. Using this standard position reduces confusion. It does not matter how the body being described is oriented, the terms are used as if it is in anatomical position. Regions of the Human Body. The human body is shown in anatomical position in an a anterior view and a b posterior view.
The regions of the body are labeled in boldface. A body that is lying down is described as either prone or supine. These terms are sometimes used in describing the position of the body during specific physical examinations or surgical procedures. Figure 2. Directional Terms Applied to the Human Body. Paired directional terms are shown as applied to the human body. Certain directional anatomical terms appear throughout this and any other anatomy textbook Figure 2.
These terms are essential for describing the relative locations of different body structures. Commit these terms to memory to avoid confusion when you are studying or describing the locations of particular body parts. Figure 3. Planes of the Body. The three planes most commonly used in anatomical and medical imaging are the sagittal, frontal or coronaland transverse plane.
We call these scans. Body sections and scans can be correctly interpreted, however, only if the viewer understands the plane along which the section was made. The body maintains its internal organization by means of membranes, sheaths, and other structures that separate compartments.
These cavities contain and protect delicate internal organs, and the ventral cavity allows for significant changes in the size and shape of the organs as they perform their functions. The lungs, heart, stomach, and intestines, for example, can expand and contract without distorting other tissues or disrupting the activity of nearby organs.
Figure 4. Dorsal and Ventral Body Cavities. The ventral cavity includes the thoracic and abdominopelvic cavities and their subdivisions. The dorsal cavity includes the cranial and spinal cavities. The posterior dorsal and anterior ventral cavities are each subdivided into smaller cavities.
Just as the brain and spinal cord make up a continuous, uninterrupted structure, the cranial and spinal cavities that house them are also continuous. The brain and spinal cord are protected by the bones of the skull and vertebral column and by cerebrospinal fluid, a colorless fluid produced by the brain, which cushions the brain and spinal cord within the posterior dorsal cavity.
The Black Lives Matter movement explained
The thoracic cavity contains the lungs and the heart, which is located in the mediastinum.Organized activism by and on behalf of women continued through the third and fourth waves of feminism from the mids and the early s, respectively. In the aftermath of World War IIthe lives of women in developed countries changed dramatically.
Household technology eased the burdens of homemaking, life expectancies increased dramatically, and the growth of the service sector opened up thousands of jobs not dependent on physical strength. It became a worldwide best seller and raised feminist consciousness by stressing that liberation for women was liberation for men too.
Women who had been told that they had it all—nice houses, lovely children, responsible husbands—were deadened by domesticity, she said, and they were too socially conditioned to recognize their own desperation. The Feminine Mystique was an immediate best seller.
Friedan had struck a chord. By June they had concluded that polite requests were insufficient. The organization was not an instant success. By the end of its second year, NOW had just 1, members and was racked by ideological divisions. Constitution to ensure equality of rights, regardless of sexand the other demanded greater access to contraception and abortion.
When some NOW members called for repeal of all abortion laws, other members left the fledgling organization, convinced that this latest action would undermine their struggles against economic and legal discrimination. Ironically, sexist attitudes had pervaded s radical politics, with some women being exploited or treated unequally within those movements. Although they lacked the kind of coherent national structure NOW had formed, liberation groups sprang up in Chicago, Toronto, Seattle, Detroit, and elsewhere.
It had no officers, no mailing address, no printed agenda. What it did have was attitude. The Redstockings also held speak-outs on rape to focus national attention on the problem of violence against women, including domestic violence. NOW leaders were looking for reform.

Most were trained artisans who had spent years learning their craft, and they feared that unskilled machine operators were robbing them of their livelihood. The first major instances of machine breaking took place in in Nottingham, and the practice soon spread across the English countryside.
Machine-breaking Luddites attacked and burned factories, and in some cases they even exchanged gunfire with company guards and soldiers.3m ppe distributors
