Sex–gender distinctionThough the terms sex and gender have been used interchangeably since at least the fourteenth century, in contemporary academic literature they usually have distinct meanings. Sex generally refers to an organism's biological sex, while gender usually refers to either social roles typically associated with the sex of a person (gender role) or personal identification of one's own gender based on an internal awareness (gender identity).
Grammatical genderIn linguistics, a grammatical gender system is a specific form of a noun class system, where nouns are assigned to gender categories that are often not related to the real-world qualities of the entities denoted by those nouns. In languages with grammatical gender, most or all nouns inherently carry one value of the called gender; the values present in a given language (of which there are usually two or three) are called the genders of that language.
VulnerabilityVulnerability refers to "the quality or state of being exposed to the possibility of being attacked or harmed, either physically or emotionally." A window of vulnerability (WOV) is a time frame within which defensive measures are diminished, compromised, or lacking. The understanding of social and environmental vulnerability, as a methodological approach, involves the analysis of the risks and assets of disadvantaged groups, such as the elderly. The approach of vulnerability in itself brings great expectations of social policy and gerontological planning.
Women's historyWomen's history is the study of the role that women have played in history and the methods required to do so. It includes the study of the history of the growth of woman's rights throughout recorded history, personal achievements over a period of time, the examination of individual and groups of women of historical significance, and the effect that historical events have had on women.
Gender pay gapThe gender pay gap or gender wage gap is the average difference between the remuneration for men and women who are working. Women are generally found to be paid less than men. In the United States, for example, the average annual salary of a woman is 83% that of a man. However, this figure changes when controlled for confounding factors such as differences in hours worked, occupations chosen, education, job experience, and level of danger at work. Attempts to control for these factors arrive at adjusted figures from 95% to 99%.
