The Leslie speaker is a specially constructed amplifier/loudspeaker used to create special audio effects using the Doppler effect. Named after its inventor, Donald Leslie, it is particularly associated with the Hammond organ, an electric organ invented by Laurens Hammond in 1934 and manufactured by the Hammond Organ Company. While the Hammond organ was originally sold to churches as a lower-cost alternative to the wind-driven pipe organ, in the 1960s and 1970s it became a standard keyboard instrument for jazz, blues, rock music, church and gospel music. The Hammond/Leslie combination has become an element in many genres of music. Both brands are currently owned by Suzuki Musical Instrument Corporation.
Unlike a high fidelity loudspeaker, the Leslie is specifically designed, via reproduction of the Doppler effect, to alter or modify sound. Although there have been many variations over the years, the classic Leslie speaker consists of two driver units – a treble unit with horns, and a bass unit, and a crossover that divided the frequencies between the horn and the woofer. The key feature is that both the horns (in reality one working horn with a dummy to counter-balance it) and a sound baffle or scoop for the bass are electrically rotated to create ‘Doppler effect based’ vibrato, tremolo and chorus effects. The rotating elements can be stopped, switched between slow (chorale) and fast (tremolo), or transitioned between the two settings.

Transparency International (TI) is a non-governmental organization that monitors and publicizes corporate and political corruption in international development. It publishes an annual Corruption Perceptions Index, a comparative listing of corruption worldwide. The headquarters is located in Berlin, Germany but operates through more than 70 national chapters around the world.
TI was founded in 1993 through the initiative of Peter Eigen, a former regional director for the World Bank. In 1995, TI developed the Corruption Perceptions Index (CPI). The CPI ranked nations on the prevalence of corruption within each country, based upon surveys of business people. The CPI was subsequently published annually. It was criticized for poor methodology and unfair treatment of developing nations, while also being praised for highlighting corruption and embarrassing governments.

A bokode is a type of data tag which holds thousands of times more information than a barcode. They were developed by a team at the MIT Media Lab. The bokode pattern is a tiled series of Data Matrix codes. The name is a portmanteau of the words bokeh (a photographic term) and barcode – rewritable bokodes are called bocodes. They are much smaller than a barcode and are circular in shape with a diameter of 3mm. A bokode consists of an LED covered with a mask and a lens. They are readable from different angles and from 4 meters (13 feet) away by an SLR camera.
Currently they are expensive to produce as the LED requires power, but there are prototypes which manage with reflected light. Bokodes represent a privacy advantage compared to Radio-frequency identification tags (RFID): bokodes can be covered up, whereas active as well as passive RFID tags can be read from a distance with equipment that can receive radio signals.

Lewis Hine (1874 – 1940) was an American sociologist and photographer. Hine used his camera as a tool for social reform. His photographs were instrumental in changing the child labor laws in the United States. Born in Oshkosh, Wisconsin in 1874. After his father died in an accident, he began working and saved his money for a college education.
Hine studied sociology at the University of Chicago, Columbia University and New York University. He became a teacher in New York City at the Ethical Culture School, where he encouraged his students to use photography as an educational medium. The classes traveled to Ellis Island in New York Harbor, photographing the thousands of immigrants who arrived each day. Between 1904 and 1909, Hine took over 200 plates (photographs), and eventually came to the realization that his vocation was photojournalism.

Cheez Whiz is a thick processed cheese sauce or spread sold by Kraft Foods. It was developed by a team led by food scientist Edwin Traisman and was first marketed in 1953. The bright orange, viscous paste usually comes in a glass jar and is used as a topping for celery, cheesesteaks, corn chips, hot dogs and other foods. It is marketed in Canada, México, the Philippines, the United States and Venezuela.
Cheez Whiz is one of a number of ‘processed cheese foods,’ a category including some types of individually-wrapped cheese slices. These products contain regular cheese that has been reprocessed along with additional ingredients such as emulsifiers and stabilizing agents, such as xanthan gum or carrageenan. These products derive their tanginess and flavor from additional ingredients such as citric acid and flavoring compounds. Annatto is used for coloring. In some markets, the product has been sold in a narrow jar that tapered towards the base when sold as a spread. When Cheez Whiz is advertised as a dip or a sauce, the jars are larger and more of a squat cylindrical shape.

Easy Cheese is the trademark for a processed cheese product distributed by Kraft Foods, also referred to as aerosol cheese or spray cheese, and is a descendant of squeeze cheese (a semi-solid cheesefood from the 1970s packaged in a squeezable plastic tube). It comes packaged in a spray can, much like canned whipped cream and does not require refrigeration. Easy Cheese contains milk, water, whey protein concentrate, canola oil, milk protein concentrate, sodium citrate, sodium phosphate, calcium phosphate, lactic acid, sorbic acid, sodium alginate, apocarotenal, annatto, cheese culture, and enzymes.
Although sometimes called ‘aerosol cheese,’ its container is not actually an aerosol spray can. Rather, the can contains a piston and a barrier plastic cap which squeezes the cheese through the nozzle in a solid column when the nozzle is pressed and the propellant expands in volume. The propellant, therefore, does not mix with the cheese. This explains why the can has a small rubber plug on its base. The can design also ensures that the cheese can be dispensed with the can upright or inverted.

Processed cheese is a food product made from normal cheese and sometimes other unfermented dairy ingredients, plus emulsifiers, extra salt, food colorings, or whey. Many flavors, colors, and textures of processed cheese exist. In the United States, the most recognizable variety of processed cheese is sold under the name American cheese, although this name also has other meanings. The Laughing Cow is an example of processed cheese.
Although processed cheese was first invented in 1911 by Walter Gerber of Thun, Switzerland, it was James L. Kraft who first applied for an American patent for his method in 1916. Kraft Foods also created the first commercially available sliced processed cheese, which was introduced in 1950. This form of sliced cheese and its derivatives have become commonplace in the United States, most notably used for cheeseburgers and grilled cheese sandwiches.

Kraft Singles is a processed ‘cheese product’ manufactured and sold by Kraft Foods, introduced in 1949. Although processed cheese was first invented in 1911 by Walter Gerber of Thun, Switzerland, it was James L. Kraft who first applied for an American patent for his method in 1916. Kraft Foods also created the first commercially available sliced processed cheese, which was introduced in 1950.
One of the more famous ad campaigns in the 1980s claimed that each ¾ ounce slice contained ‘five ounces of milk’ (with milk being poured into a glass next to Kraft Singles), which makes them taste better than imitation cheese slices made mostly with vegetable oil and water (with oil being poured into a glass next to imitation cheese) and hardly any milk. The campaign was lambasted for its implications that each slice contained the same amount of calcium as a five ounce glass of milk and also more calcium than imitation cheese slices, which eventually led to a ruling by the Federal Trade Commission in 1992 that ordered Kraft to stop making false claims in its advertising. Kraft removed the ads, but continues to taut the use of milk in its ‘cheese products.’

American cheese is a processed cheese, mild in flavor, with a medium-firm consistency, which melts easily. It was originally only white in color, but is usually now darkened to yellow or orange, typically with annatto, a natural food coloring.
At one time it was made from a blend of cheeses, most often Colby and Cheddar, but today’s American cheese is typically manufactured from raw ingredients, such as milk, whey, milkfat, milk protein concentrate, whey protein concentrate, and salt. In many jurisdictions, it does not meet the legal definition of cheese and must be labeled as ‘cheese analogue,’ ‘cheese product,’ ‘processed cheese,’ or similar and is commonly referred to as ‘plastic cheese’ or ‘burger cheese’ in the UK.

Freeter is a Japanese expression for people between the ages of 15 and 34 who lack full time employment or are unemployed, excluding housewives and students. The term originally included young people who deliberately chose not to become salary-men, even though jobs were available at the time. Freeters may also be described as underemployed or freelance workers.
These people do not start a career after high school or university, but instead earn money from low skilled and low paid jobs. The low income makes it difficult for freeters to start a family, and the lack of qualifications makes it difficult to start a career at a later point in life. Freeters have sometimes been glamorized as people pursuing their dreams and trying to live life to the fullest.

Laziness (also called indolence) is a disinclination to activity or exertion despite having the ability to do so. It is often used as a pejorative; related terms for a person seen to be lazy include couch potato, slacker, and in Australian slang, bludger.
Despite Sigmund Freud’s discussion of the pleasure principle, American psychologist Leonard Carmichael notes that ‘laziness is not a word that appears in the table of contents of most technical books on psychology… It is a guilty secret of modern psychology that more is understood about the motivation of thirsty rats and hungry pecking pigeons as they press levers or hit targets than is known about the way in which poets make themselves write poems or scientists force themselves into the laboratory when the good golfing days of spring arrive.’

Hilti develops, manufactures, and markets products for the construction and building maintenance industries, primarily to the professional end-user. It concentrates primarily on hammer drills, firestops, and installation systems, but manufactures and markets an array of tools (including cordless electric drills, heavy angle drills, laser levels, power saws, and fasteners). Hilti is based in Liechtenstein, and is the principality’s largest employer. The company employs more than 20,000 people worldwide with over 2,500 employees in the United States. Hilti’s North American headquarters has been located in Tulsa, Oklahoma, since 1979.
The Hilti Group invests over US$160 million annually in researching and developing safer and more efficient building technologies. A recent example of this R&D in power tool technology is Hilti’s TPS (Theft Protection System), which relies on RF technology to prevent unauthorized users from activating power tools, thus discouraging theft. Similarly, Hilti’s ATC (Active Torque Control) technology monitors tool-body movement to prevent equipment from twisting out of the operator’s grip and causing injury. Other developments include improved design of chemical and mechanical anchors for better durability during seismic events, thus helping to save lives during natural disasters.
