, 2015 This chapter surveys the sizable and growing literature on coalition formation. We refer to theories in which one or more groups of agents (“coalitions”) deliberately get together to jointly determine their actions. The defining idea of a coalition, in this chapter, is that of a group which can coordinate agreements among its members, while it ...

Tarsal Coalitions – Calcaneonavicular Coalitions
Foot and Ankle Clinics, 2015Calcaneonavicular coalitions are an important cause of adolescent foot pain and deformity. The congenital condition is characterized by an aberrant osseous, cartilaginous, or fibrinous union of the calcaneal and navicular bones. Calcaneonavicular coalitions are the most common form of tarsal coalitions identified within epidemiologic studies.

Purpose of review Tarsal coalitions may cause painful pes planovalgus and recurrent sprains, and can lead to arthrosis if improperly managed. In this review, we discuss the current topics related to talocalcaneal and calcaneonavicular coalitions.

The cubonavicular coalition is a rare form of tarsal coalition that probably accounts for less than 1% of all coalitions. The authors present a new case of cubonavicular coalition as well as the findings of the 17 previously published accounts. Etiology, clinical presentation, diagnosis, and treatment of the condition are discussed.

Talocalcaneal coalitions present with complaints of flatfeet, foot or ankle pain after minor injury, or recurrent ankle sprains. Physical examination findings include limited subtalar motion and prominence inferior to the medial malleolus. Use of computed topography (CT) scan is recommended for preoperative planning.

Tarsal coalitions are recognized as a congenital anomaly whereby the two or more bones of the hindfoot and midfoot are fused resulting in limitation of foot motion and pain. Tarsal coalitions were found to be the cause of painful flatfeet in adolescents and young adults.

Intercarpal coalitions are well-known but poorly documented entities, resulting from incomplete cavitation of a common embryologic carpal precursor during the fourth to eighth weeks of intrauterine life. At our institution we have collected a series of 36 cases of carpal coalition in 24 persons. We found the condition to be much more common in American

Coalitions and Coalition Building
2021Coalitions are mechanisms to bring organizations and individuals together for collective efforts ranging from short-term crisis responses to longer-term problem-solving for social change. Coalitions create a specific type of collaboration that is dynamic and responsive to current events in the social, political, economic, and physical environments.

This paper examines recent theoretical developments of the theory of coalition stability. It focuses on the relationship between the incentives to defect from a coalition, the size of the resulting equilibrium coalition structure, and the different assumptions on membership rules, coalition behaviour, players' conjectures, etc.

A tarsal coalition is an aberrant union between 2 or more tarsal bones and can be classified as osseous (synostosis) or nonosseous (cartilaginous [synchondrosis] or fibrous [syndesmosis]). This union may be complete or partial and the joints in the hindfoot and midfoot are most commonly affected.
