The first description of cooperative binding to a multi-site protein was developed by A.V. Hill. [4] Drawing on observations of oxygen binding to hemoglobin and the idea that cooperativity arose from the aggregation of hemoglobin molecules, each one binding one oxygen molecule, Hill suggested a phenomenological equation that has since been named after him:
Ligands can either have positive cooperativity, negative cooperativity, or non-cooperativity. The sigmoidal shape of hemoglobin's oxygen-dissociation curve results from cooperative binding of oxygen to hemoglobin. An example of positive cooperativity is the binding of oxygen to hemoglobin.
David Johnson, Deutsch's student in the study of social psychology, with his brother Roger Johnson, a science educator, and their sister, educator Edye Johnson Holubec, further developed positive interdependence theory as part of their research and work in teacher and professional training at the Cooperative Learning Center at the University of Minnesota (founded in 1969).
Positively cooperative binding: Once one ligand molecule is bound to the enzyme, its affinity for other ligand molecules increases. For example, the Hill coefficient of oxygen binding to haemoglobin (an example of positive cooperativity) falls within the range of 1.7–3.2. [5] <.
Shared intentionality is a concept in psychology that describes the human capacity to engage with the psychological states of others. According to conventional wisdom in cognitive sciences, shared intentionality supports the development of everything from cooperative interactions and knowledge assimilation to moral identity and cultural evolution that provides building societies, being a pre ...
The positive reciprocity norm is a common social expectation in which a person who helps another person can expect positive feedback whether in the form of a gift, a compliment, a loan, a job reference, etc. In social psychology, positive reciprocity refers to responding to a positive action with another positive action (rewarding kind actions).
A New Jersey family is suing DraftKings after a father of two gambled away more than $1 million of his family’s money across four years. The man, known by his username Mdallo1990, allegedly lost ...
Researchers suggested that a combination of low self-directedness and low cooperativeness form a general factor common to all personality disorders. [4] The specific combination of low self-directedness, low cooperativeness, and high self-transcendence has been described as a "schizotypal personality" style by Cloninger and colleagues, [4] and has been found to be associated with high levels ...
