Gens (behaviour)

In animal behaviour, a gens (pl. gentes) or host race is a host-specific lineage of a brood parasite species. Brood parasites such as cuckoos, which use multiple host species to raise their chicks, evolve different gentes, each one specific to its host species. This specialisation allows the parasites to lay eggs that mimic those of their hosts, which in turn reduces the chances of the eggs being rejected by the hosts.

The exact mechanisms of the evolution and maintenance of gens is still a matter of some research. However, it is believed that in common cuckoos, gens-specific properties are sex-linked and lie on the W chromosome of the female. Male cuckoos, which like all male birds have no W chromosome, are able to mate with females of any gens, and thereby maintain the cuckoo as one species. This is not the case in other brood parasites, such as cowbirds, in which both the male and female imprint on their preferred host. This leads to speciation, such as the indigo bird, which is suggested by the fact they have a more recent evolutionary origin than their hosts.

Behavior

Behavior or behaviour (see spelling differences) is the range of actions and mannerisms made by individuals, organisms, systems, or artificial entities in conjunction with themselves or their environment, which includes the other systems or organisms around as well as the (inanimate) physical environment. It is the response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary.

Health behavior

Health behavior refers to a person's beliefs and actions regarding their health and well-being. Health behaviors are direct factors in maintaining a healthy lifestyle. Health behaviors are influenced by the social, cultural and physical environments in which we live and work. They are shaped by individual choices and external constraints. Positive behaviors help promote health and prevent disease, while the opposite is true for risk behaviors. Health behaviors are early indicators of population health. Because of the time lag that often occurs between certain behaviors and the development of disease, these indicators may foreshadow the future burdens and benefits of health-risk and health-promoting behaviors. Health behaviors do not occur in isolation—they are influenced and constrained by social and cultural norms.

Behavior (film)

Behavior (Spanish: Conducta) is a 2014 Cuban drama film directed by Ernesto Daranas. In English writing, the film is usually referred to by the title Behavior. The film premiered in February 2014, and then played at the Málaga Film Festival before having its US premieres simultaneously at the Chicago Latino Film Festival and Havana Film Festival New York in April 2014.Behavior was then screened in the Contemporary World Cinema section at the 2014 Toronto International Film Festival. It was selected as the Cuban entry for the Best Foreign Language Film at the 87th Academy Awards, but was not nominated.

Cast

Awards

At the Málaga Spanish Film Festival, Behavior won the awards in the Latin American section for best film, best director, and best actress (Alina Rodriguez), as well as the audience award in that section.

The film won the Havana Star Prize for Best Film at the 15th Havana Film Festival New York, with Alina Rodriguez winning for Best Actress.

Gens

In ancient Rome, a gens (/ˈɡɛns/ or /ˈdʒɛnz/), plural gentes, was a family, consisting of all those individuals who shared the same nomen and claimed descent from a common ancestor. A branch of a gens was called a stirps (plural stirpes). The gens was an important social structure at Rome and throughout Italy during the period of the Roman Republic. Much of an individual's social standing depended on the gens to which he belonged. Certain gentes were considered patrician, others plebeian, while some had both patrician and plebeian branches. The importance of membership in a gens declined considerably in imperial times.

Origin of the gens

The word gens is sometimes translated as "race" or "nation", meaning a people descended from a common ancestor (rather than sharing a common physical trait). It can also be translated as "clan" or "tribe", although the word tribus has a separate and distinct meaning in Roman culture. A gens could be as small as a single family, or could include hundreds of individuals. According to tradition, in 479 BC the Fabii alone were able to field a militia consisting of three hundred and six men of fighting age. The concept of the gens was not uniquely Roman, but was shared with communities throughout Italy, including those who spoke Italic languages such as Latin, Oscan, and Umbrian, as well as the Etruscans. All of these peoples were eventually absorbed into the sphere of Roman culture.

Arcade

An arcade emulator is a program that emulates one or more arcade games on a different computer, such as a PC. The first known arcade emulation available publicly was the Williams Digital Arcade series from Digital Eclipse Software, released for the Macintosh in 1994. This series featured the Williams Electronics' arcade classics Joust,Defender and Robotron: 2084. In 1995, it was repackaged and expanded upon as Williams Arcade Classics for the PC. DASArcade (written by David Alan Spicer) was arguably the first PC-based multiple arcade game emulator. This was distinct from Digital Eclipse's release in that only one program was required to emulate more than one arcade game, rather than one program per game. The first version of DASArcade was released later in 1995 and emulated a few titles including Pac-Man and Frogger (two years before MAME which now dominates arcade emulation). DASArcade evolved into Sparcade which emulates over 70 games.
