Where Once We Walked: Where Once We Walked (full title: "Where Once We Walked: A Guide to the Jewish Communities Destroyed in The Holocaust"), compiled by noted genealogist Gary Mokotoff and Sallyann Amdur Sack, is a gazetteer of 37,000 town names in Central and Eastern Europe focusing on those with Jewish populations in the 19th and first half of the 20th centuries and most of whose Jewish communities were almost or completely destroyed during The Holocaust.

Gender advertisement: Gender advertisement refers to the images in advertising that depict stereotypical gender roles and displays.  Gender displays are used heavily in advertising in order to establish the role of one gender in relation with the other, and some scholars argue that advertisers are obsessed with gender.  Advertisers focus on gender relationships, because people define themselves by gender, and gender can be "communicated at a glance", making it easy for advertisers to use this theme in their work.  The effects of advertising on body image have been studied by researchers, ranging from psychologists to marketing professionals.  "These days we know that the media and body image are closely related.  Particularly, the body image advertising portrays affects our own body image.  Of course, there are many other things that influence our body image: parenting, education, intimate relationships, and so on.  The popular media does have a big impact, though" This is because thousands of advertisements contain messages about physical attractiveness and beauty, examples which include commercials for clothes, cosmetics, weight reduction, and physical fitness.  Researchers have conducted studies in an attempt to see if such advertisements have effects on teenage body image, and what those effects might be.

Carpaine: Carpaine is one of the major alkaloid components of papaya leaves which has been studied for its cardiovascular effects.  Circulatory effects of carpaine were studied in Wistar male rats weighing 314 +/- 13 g, under pentobarbital (30 mg/kg) anesthesia.  Increasing dosages of carpaine from 0.5 mg/kg to 2.0 mg/kg resulted in progressive decrease in systolic, diastolic, and mean arterial blood pressure.  Selective autonomic nervous blockade with atropine sulfate (1 mg/kg) or propranolol hydrochloride (8 mg/kg) did not alter the circulatory response to carpaine.  Carpaine, 2 mg/kg, reduced cardiac output, stroke volume, stroke work, and cardiac power, but the calculated total peripheral resistance remained unchanged.  It is concluded from these results that carpaine affects the myocardium directly.  The effects of carpaine may be related to its macrocyclic dilactone structure, a possible cation chelating structure.

1948 Donora smog: The 1948 Donora smog was a historic air inversion that resulted in a wall of smog that killed 20 people and sickened 7,000 more in Donora, Pennsylvania, a mill town on the Monongahela River, 24 mi southeast of Pittsburgh.  The event is commemorated by the Donora Smog Museum.

Gestadienol acetate: Gestadienol acetate (developmental code name CIBA-31458-Ba or CIBA-31458), also known as 6-dehydro-17α-acetoxy-19-norprogesterone, is a synthetic, steroidal, orally active progestin of the 19-norprogesterone and 17α-hydroxyprogesterone groups which was described in the literature in 1967 and was never marketed.  It has no androgenic or estrogenic effects.  The effects of gestadienol acetate on the endometrium and its general pharmacology were studied in a clinical trial in women.  It has also been studied in a clinical trial for benign prostatic hyperplasia in men, but was found to be ineffective.  Gestadienol acetate is the C17α acetate ester of gestadienol.

Context effect: A context effect is an aspect of cognitive psychology that describes the influence of environmental factors on one's perception of a stimulus.  The impact of context effects is considered to be part of top-down design.  The concept is supported by the theoretical approach to perception known as constructive perception.  Context effects can impact our daily lives in many ways such as word recognition, learning abilities, memory, and object recognition.  It can have an extensive effect on marketing and consumer decisions.  For example, research has shown that the comfort level of the floor that shoppers are standing on while reviewing products can affect their assessments of product's quality, leading to higher assessments if the floor is comfortable and lower ratings if it is uncomfortable.  Because of effects such as this, context effects are currently studied predominantly in marketing.

Mary Amdur: Mary Ochsenhirt Amdur (February 18, 1921 – February 16, 1998) was an American toxicologist and public health researcher who worked primarily on pollution.  She was charged with studying the effects of the 1948 Donora smog, so she specifically looked into the effects of inhaling Sulfuric acid by experimenting on guinea pigs.  Her findings on the respiratory effects related to sulfuric acid led to her being threatened, to her funding being pulled, and to her losing her job at the Harvard School of Public Health in 1953.  Undeterred by the setback, she carried on her research in a different role at Harvard, and subsequently at MIT and New York University.  Despite the early controversy related to her work, it was used in the creation of standards in air pollution, and towards the end of her life she received numerous awards and accolades.

Mary's Harbour: Mary's Harbour is a town in the Canadian province of Newfoundland and Labrador.  The town had a population of 474 in the Canada 2006 Census.  It is serviced by Mary's Harbour Airport.  Mary's Harbour surrounds the St. Mary's River.  St. Mary's River was the site of a salmon fishery as early as the 1780s.  However Mary's Harbour was not a permanent settlement until after a fire at Battle Harbour in 1930.  The International Grenfell Association decided to relocate its hospital and boarding school, destroyed by the fire, from Battle Harbour to Mary's Harbour.  Mary's Harbour has always depended on the fishery for its livelihood.  Since the Collapse of the Atlantic northwest cod fishery the community has thrived on the crab fishery.  The Labrador Fishermen's Union Shrimp Company employs over 120 people at the local crab processing facility.  It is also the gateway to the National Historic District of Battle Harbour.

The Allegory of Good and Bad Government: The Allegory of Good and Bad Government is a series of three fresco panels painted in the Sala Dei Nove by Ambrogio Lorenzetti from around February 26, 1338 to May 29, 1339.  The paintings are located in the Sala dei Nove (Salon of Nine or Council Room) in the Palazzo Pubblico (or Town Hall) of the city of Siena, Italy.  The series consists of six different scenes: "Allegory of Good Government", "Allegory of Bad Government", "Effects of Bad Government in the City", "Effects of Bad Government in the Country", "Effects of Good Government in the City" and "Effects of Good Government in the Country" (the titles are all modern conveniences).
