Sex ratios

The sex ratio of male to female dragonflies varies both temporally and spatially. Adult dragonflies have a high male-biased ratio at breeding habitats. The male-bias ratio has contributed partially to the females using different habitats to avoid male harassment.

As seen in Hine's emerald dragonfly (Somatochlora hineana), male populations use wetland habitats, while females use dry meadows and marginal breeding habitats, only migrating to the wetlands to lay their eggs or to find mating partners.

Unwanted mating is energetically costly for females because it affects the amount of time that they are able to spend foraging.

Self-handicapping is a cognitive strategy by which people avoid effort in the hopes of keeping potential failure from hurting self-esteem.[1] It was first theorized by Edward E. Jones and Steven Berglas,[2] according to whom self-handicaps are obstacles created, or claimed, by the individual in anticipation of failing performance.[3]
Learned Helplessness is behaviour exhibited by a subject after enduring repeated aversive stimuli beyond their control. It was initially thought to be caused from the subject's acceptance of their powerlessness: discontinuing attempts to escape or avoid the aversive stimulus, even when such alternatives are unambiguously presented. Upon exhibiting such behavior, the subject was said to have acquired learned helplessness.[1][2] Over the past few decades, neuroscience has provided insight into learned helplessness and shown that the original theory actually had it backwards: the brain's default state is to assume that control is not present, and the presence of "helpfulness" is what is actually learned.[3]

On 27 June 1980, Itavia Flight 870 (IH 870, AJ 421), a McDonnell Douglas DC-9 passenger jet en route from Bologna to Palermo, Italy, crashed into the Tyrrhenian Sea between the islands of Ponza and Ustica, killing all 81 people on board. Known in Italy as the Ustica massacre ("strage di Ustica"), the disaster led to numerous investigations, legal actions and accusations, and continues to be a source of controversy, including claims of conspiracy by the Italian government and others. The Prime Minister of Italy at the time, Francesco Cossiga, attributed the crash to a missile fired from a French Navy aircraft, despite contrary evidence presented in a 1994 report. On 23 January 2013, Italy's top criminal court ruled that there was "abundantly" clear evidence that the flight was brought down by a missile.
The Cavalese cable car disaster of 1998, also called the Strage del Cermis ("Massacre at Cermis") occurred on 3 February 1998, near the Italian town of Cavalese, a ski resort in the Dolomites some 40 km (25 mi) northeast of Trento. Twenty people died when a United States Marine Corps EA-6B Prowler aircraft, while flying too low, against regulations, in order for the pilots to "have fun" and "take videos of the scenery", cut a cable supporting a gondola of an aerial tramway.

Propaganda Due (Italian pronunciation: [propaˈɡanda ˈduːe]; P2) was a Masonic lodge under the Grand Orient of Italy, founded in 1877. Its Masonic charter was withdrawn in 1976, and it transformed into a clandestine, pseudo-Masonic, ultraright[1][2][3] organization operating in contravention of Article 18 of the Constitution of Italy that banned secret associations. In its latter period, during which the lodge was headed by Licio Gelli, P2 was implicated in numerous Italian crimes and mysteries, including the collapse of the Vatican-affiliated Banco Ambrosiano, the murders of journalist Mino Pecorelli and banker Roberto Calvi, and corruption cases within the nationwide bribe scandal Tangentopoli. P2 came to light through the investigations into the collapse of Michele Sindona's financial empire.[4]
Operation Gladio is the codename for clandestine "stay-behind" operations of armed resistance that was planned by the Western Union (WU), and subsequently by NATO, for a potential Warsaw Pact invasion and conquest in Europe. Although Gladio specifically refers to the Italian branch of the NATO stay-behind organizations, "Operation Gladio" is used as an informal name for all of them. Stay-behind operations were prepared in many NATO member countries, and some neutral countries.[1]
La strategia della tensione in Italia è una teoria politica che indica generalmente un periodo storico molto tormentato della storia d'Italia, in particolare negli anni settanta del XX secolo, conosciuto come anni di piombo e che, mediante un disegno eversivo, tendeva alla destabilizzazione o al disfacimento degli equilibri precostituiti.

The Barnum effect, also called the Forer effect, or less commonly the Barnum-Forer effect, is a common psychological phenomenon whereby individuals give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically to them, that are in fact vague and general enough to apply to a wide range of people. This effect can provide a partial explanation for the widespread acceptance of some paranormal beliefs and practices, such as astrology, fortune telling, aura reading, and some types of personality tests.

“Slim by Chocolate!” the headlines blared. A team of German researchers had found that people on a low-carb diet lost weight 10 percent faster if they ate a chocolate bar every day. It made the front page of Bild, Europe’s largest daily newspaper, just beneath their update about the Germanwings crash. From there, it ricocheted around the internet and beyond, making news in more than 20 countries and half a dozen languages. It was discussed on television news shows. It appeared in glossy print, most recently in the June issue of Shape magazine (“Why You Must Eat Chocolate Daily,” page 128). Not only does chocolate accelerate weight loss, the study found, but it leads to healthier cholesterol levels and overall increased well-being. The Bild story quotes the study’s lead author, Johannes Bohannon, Ph.D., research director of the Institute of Diet and Health: “The best part is you can buy chocolate everywhere.”

Amelio Robles Ávila (3 November 1889 – 9 December 1984) was a colonel during the Mexican Revolution. Assigned female at birth with the name Amelia Robles Ávila, Robles fought in the Mexican Revolution, rose to the rank of colonel, and lived openly as a man from age 24 until his death at age 95.
Alan L. Hart (October 4, 1890 – July 1, 1962) was an American physician, radiologist, tuberculosis researcher, writer and novelist. He was in 1917–18 one of the first trans men to undergo hysterectomy in the United States, and lived the rest of his life as a man. He pioneered the use of x-ray photography in tuberculosis detection, and helped implement TB screening programs that saved thousands of lives.[1]
Many people have engaged in cross-dressing during wartime under various circumstances and for various motives. This has been especially true of women, whether while serving as a soldier in otherwise all-male armies, while protecting themselves or disguising their identity in dangerous circumstances, or for other purposes.
Breeching was the occasion when a small boy was first dressed in breeches or trousers. From the mid-16th century[1] until the late 19th or early 20th century, young boys in the Western world were unbreeched and wore gowns or dresses until an age that varied between two and eight.[2] Various forms of relatively subtle differences usually enabled others to tell little boys from little girls, in codes that modern art historians are able to understand.

A glass ceiling is a metaphor used to represent an invisible barrier that keeps a given demographic (typically applied to minorities) from rising beyond a certain level in a hierarchy.[1]
The glass cliff is the phenomenon of women in leadership roles, such as executives in the corporate world and female political election candidates, being likelier than men to achieve leadership roles during periods of crisis or downturn, when the chance of failure is highest.

The Kessler syndrome (also called the Kessler effect,[1][2] collisional cascading, or ablation cascade), proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions.[3] One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations.[3]

The Book of the City of Ladies or Le Livre de la Cité des Dames (finished by 1405), is perhaps Christine de Pizan's most famous literary work, and it is her second work of lengthy prose. Pizan uses the vernacular French language to compose the book, but she often uses Latin-style syntax and conventions within her French prose.[1] The book serves as her formal response to Jean de Meun's popular Roman de la Rose. Pizan combats Meun's statements about women by creating an allegorical city of ladies. She defends women by collecting a wide array of famous women throughout history. These women are "housed" in the City of Ladies, which is actually the book. As Pizan builds her city, she uses each famous woman as a building block for not only the walls and houses of the city, but also as building blocks for her thesis. Each woman added to the city adds to Pizan's argument towards women as valued participants in society. She also advocates in favour of education for women.[2]
