Analysis of information sources in references of the Wikipedia article "Discrimination" in English language version.
Discrimination occurs when a person is unable to enjoy his or her human rights or other legal rights on an equal basis with others because of an unjustified distinction made in policy, law or treatment.
Discrimination is the unfair or prejudicial treatment of people and groups based on characteristics such as race, gender, age or sexual orientation.
If a being suffers, there can be no moral justification for refusing to take that suffering into consideration. ... This is why the limit of sentience ... is the only defensible boundary of concern for the interests of others. ... Similarly those I would call 'speciesists' give greater weight to their own species when there is a clash between their interests and the interests of those of other species.
GENDER OR SEX DISCRIMINATION: This term refers to the types of gender bias that have a negative impact. The term has legal, as well as theoretical and psychological, definitions. Psychological consequences can be more readily inferred from the latter, but both definitions are of significance. Theoretically, gender discrimination has been described as (1) the unequal rewards that men and women receive in the workplace or academic environment because of their gender or sex difference (DiThomaso, 1989); (2) a process occurring in work or educational settings in which an individual is overtly or covertly limited access to an opportunity or a resource because of a sex or is given the opportunity or the resource reluctantly and may face harassment for picking it (Roeske & Pleck, 1983); or (3) both.
[A]s a reasonable first approximation, we can say that discrimination consists of acts, practices, or policies that impose a relative disadvantage on persons based on their membership in a salient social group. [...] [W]e can refine the first-approximation account of discrimination and say that the moralized concept of discrimination is properly applied to acts, practices or policies that meet two conditions: a) they wrongfully impose a relative disadvantage or deprivation on persons based on their membership in some salient social group, and b) the wrongfulness rests (in part) on the fact that the imposition of the disadvantage is on account of the group membership of the victims.
