Leona Mindy Roberts Helmsley (born Lena Mindy Rosenthal; July 4, 1920 – August 20, 2007) was an American businesswoman.
 She was known for her flamboyant personality and had a reputation for tyrannical behavior that earned her the sobriquet Queen of Mean.
 She was promoted by the Beber Silverstein Group and its co-founder Joyce Beber persuaded Helmsley to replace that title with Queen of the Palace Hotel instead.
Bishop Festo Kivengere (1919–1988) was a Ugandan Anglican-Christian leader referred to by many as "the Billy Graham of Africa".
 ("See endnote 4.")
 He played a huge role in a Christian revival in southwestern Uganda, but had to flee in 1973 to neighboring Kenya in fear for his life after speaking out against Idi Amin's tyrannical behavior.
Dunnellen Hall is a private mansion located at 521 Round Hill Road in Greenwich, Connecticut, USA.
 It was sold by the estate of Leona Helmsley for $35 million down from the original asking price of $125 million when it was first put up on the market in 2008.
Compulsive hoarding, also known as hoarding disorder, is a pattern of behavior that is characterized by excessive acquisition and an inability or unwillingness to discard large quantities of objects that cover the living areas of the home and cause significant distress or impairment.
 Compulsive hoarding behavior has been associated with health risks, impaired functioning, economic burden, and adverse effects on friends and family members.
 When clinically significant enough to impair functioning, hoarding can prevent typical uses of space, enough so that it can limit activities such as cooking, cleaning, moving through the house, and sleeping.
 It can also put the individual and others at risk of fires, falling, poor sanitation, and other health concerns.
 Compulsive hoarders may be aware of their irrational behavior, but the emotional attachment to the hoarded objects far exceeds the motive to discard the items.
Gecekondu (plural gecekondular) is a Turkish word meaning a house put up quickly without proper permissions, a squatter's house, and by extension, a shanty or shack.
 Gecekondu bölgesi is a neighborhood made of those gecekondular.
Social undermining is the expression of negative emotions directed towards a particular person or negative evaluations of the person as a way to prevent the person from achieving his or her goals.
 This behavior can often be attributed to certain feelings, such as dislike or anger.
 The negative evaluation of the person may involve criticizing his or her actions, efforts or characteristics.
 Social undermining is seen in relationships between family members, friends, personal relationships and co-workers.
 Social undermining can affect a person's mental health, including an increase in depressive symptoms.
 This behavior is only considered social undermining if the person's perceived action is intended to hinder their target.
 When social undermining is seen in the work environment the behavior is used to hinder the co-worker's ability to establish and maintain a positive interpersonal relationship, success and a good reputation.
 Examples of how an employee can use social undermining in the work environment are behaviors that are used to delay the work of co-workers, to make them look bad or slow them down, competing with co-workers to gain status and recognition and giving co-workers incorrect or even misleading information about a particular job.
Bullying is the use of force, threat, or coercion to abuse, intimidate, or aggressively dominate others.
 The behavior is often repeated and habitual.
 One essential prerequisite is the perception, by the bully or by others, of an imbalance of social or physical power, which distinguishes bullying from conflict.
 Behaviors used to assert such domination can include verbal harassment or threat, physical assault or coercion, and such acts may be directed repeatedly towards particular targets.
 Rationalizations of such behavior sometimes include differences of social class, race, religion, gender, sexual orientation, appearance, behavior, body language, personality, reputation, lineage, strength, size, or ability.
 If bullying is done by a group, it is called mobbing.
Prosocial behavior, or "voluntary behavior intended to benefit another", is a social behavior that "benefit[s] other people or society as a whole", "such as helping, sharing, donating, co-operating, and volunteering".
 Obeying the rules and conforming to socially accepted behaviors (such as stopping at a "Stop" sign or paying for groceries) are also regarded as prosocial behaviors.
 These actions may be motivated by empathy and by concern about the welfare and rights of others, as well as for egoistic or practical concerns, such as one's social status or reputation, hope for direct or indirect reciprocity, or adherence to one's perceived system of fairness.
 It may also be motivated by altruism, though the existence of pure altruism is somewhat disputed, and some have argued that this falls into philosophical rather than psychological realm of debate.
 Evidence suggests that pro sociality is central to the well-being of social groups across a range of scales, including schools.
 Prosocial behavior in the classroom can have a significant impact on a student’s motivation for learning and contributions to the classroom and larger community.
 Empathy is a strong motive in eliciting prosocial behavior, and has deep evolutionary roots.
A prison gang is an inmate organization that operates within a prison system, that has a corporate entity, exists into perpetuity, and whose membership is restrictive, mutually exclusive, and often requires a lifetime commitment.
 In ""The Social Order of the Underworld: How Prison Gangs Govern the American Penal System,”" the author David Skarbek argues the emergence of prison gangs are due to the dramatic increase in the prison population and inmate's demand for safety.
 Skarbek observes that in a small, homogeneous environment, people can use social norms to interrupt what behavior is acceptable, but a large, heterogeneous setting undermines social norms and acceptable behavior is more difficult to determine.
 Prison gangs are geographically and racially divided, and about 70% of prison gang members are in California and Texas.
 Skarbek suggests prison gangs function similar to a community responsibility system.
 Interactions between strangers are facilitated because you do not have to know an individual's reputation, only a gangs reputation.
 Some prison gangs are transplanted from the street.
 In some circumstances, prison gangs "outgrow" the internal world of life inside the penitentiary, and go on to engage in criminal activities on the outside.
 Gang umbrella organizations like the Folk Nation and People Nation have originated in prisons.
The Nurtured Heart Approach (NHA) is a social emotional strategy that instills greatness and transforms negative behaviors into positive behaviors, increases interrelatedness and connectivity among family members, couples, teachers and students and builds “Inner Wealth” more commonly known as character strengths and virtues.
 The NHA was created and developed by Howard Glasser who was discouraged by the lack of positive results when applying the techniques he had learned in graduate school.
 Glasser intuitively created this approach by specifically attending to the energy in relationships noticing that more energy and attention went to negative behavior rather than to positive behavior.
 Howard Glasser continues to expound on his findings for the last two decades resulting in the first Global Summit with topics in research, policy, foster care, mental health organizations, workplace, education, diverse cultures and religious affiliation and with specific psychiatric disorders.
 The Nurtured Heart Approach to parenting (NHA; Glasser & Easley, 2008) is summarized and evaluated in terms of its alignment with current theoretical perspectives and empirical evidence in family studies and developmental science.
 Originally conceived and promoted as a behavior management approach for parents of difficult children (i.e., with behavior disorders), NHA is increasingly offered as a valuable strategy for parents of any children, despite a lack of published empirical support.
 Parents using NHA are trained to minimize attention to undesired behaviors, provide positive attention and praise for compliance with rules, help children be successful by scaffolding and shaping desired behavior, and establish a set of clear rules and consequences.
 Many elements of the approach have strong support in the theoretical and empirical literature; however, some of the assumptions are more questionable, such as that negative child behavior can always be attributed to unintentional positive reinforcement by parents responding with negative attention.
 On balance, NHA appears to promote effective and validated parenting practices, but its effectiveness now needs to be tested empirically (Hektner, J, Brennan, A, & Brotherson, S., 2013).
