In this chapter collective acceptance as a group is analyzed. The result is used to give an account of group actions and beliefs as well as of group attitudes more generally. This central “positional” view is based on group authority in the sense of some authorized members (“operative” members) forming attitudes and/or acting for the group as well as possibly giving orders to group members. Also the central notion of having an attitude as a group member—assumed to be based on a group reason—is clarified. The appendix this chapter discusses social groups, I-mode and we-mode groups, mainly from an ontological point of view, and contrasts an entity view with a nonentity view.Less

This chapter presents and defends a detailed account of joint action as a group in terms of joint action based on a we-mode joint intention. A brief survey of other available accounts of joint action is given. While the chapter concentrates on acting jointly as a group (namely, we-mode joint action), weaker kinds of joint action are also briefly considered, for example, I-mode joint action and joint action based on shared we-attitudes.Less

Thus collective intentionality and the accompanying “we-perspective” both in the full, we-mode sense and in the “private”, I-mode sense are introduced. A preliminary survey of the contents of the chapters is given and the most central theses, twelve of them, of the theory are presented in this introduction.Less

This chapter begins by introducing various geometries that play important roles in the way they relate to Sasakian structures. It espouses the point of view that a geometric structure is best described as a G-structure which may or may not be (partially) integrable. Some selected topics include: Riemannian metrics, complex structures, symplectic structures, contact structures, quaternionic structures, group actions, pseudogroups, sheaves, bundles, connections, holonomy, curvature and integrability.Less

Spherical objects — motivated by considerations in the context of mirror symmetry — are used to construct special autoequivalences. Their action on cohomology can be described precisely, considering more than one spherical object often leads to complicated (braid) groups acting on the derived category. The results related to Beilinson are almost classical. Section 3 of this chapter gives an account of the Beilinson spectral sequence and how it is used to deduce a complete description of the derived category of the projective space. This will use the language of exceptional sequences and semi-orthogonal decompositions encountered here. The final section gives a simplified account of the work of Horja, which extends the theory of spherical objects and their associated twists to a broader geometric context.Less

This chapter outlines the relationship between race, ethnicity, and substantive representation via an in-depth discussion of how racial and ethnic group consciousness operates among black and Latino representatives in Congress. While all members of Congress face the pressure of making the right decisions to increase their chances at reelection, black and Latino legislators, unlike most white legislators, face an additional pressure: they are motivated by a group norm that requires them to engage in collective group action on issues of concern to other blacks and Latinos. White legislators are mainly responsible for being responsive to the constituents in their districts, whereas black and Latino legislators are also expected to represent the interests of all blacks and Latinos nationally. The strategy they pursue of “strategic group uplift” falls at the intersection of their electoral goals and their commitment to advance group interests.Less

This chapter provides an overview of equivariant cohomology. Cohomology in any of its various forms is one of the most important inventions of the twentieth century. A functor from topological spaces to rings, cohomology turns a geometric problem into an easier algebraic problem. Equivariant cohomology is a cohomology theory that takes into account the symmetries of a space. Many topological and geometrical quantities can be expressed as integrals on a manifold. Integrals are vitally important in mathematics. However, they are also rather difficult to compute. When a manifold has symmetries, as expressed by a group action, in many cases the localization formula in equivariant cohomology computes the integral as a finite sum over the fixed points of the action, providing a powerful computational tool.Less

Chapter Six provides an extended examination of the newspaper reporting of the treason trial of Obafemi Awolowo, the second major treason trial after independence. How the Nigerian press covered the trial illuminates the ways in which legal process as a mode of nation formation was woven into the daily lives of newspaper readers. Moreover, attending to that press coverage illustrates the importance of narrative and literary form in the process of national self-construction. The chapter begins by outlining the relationship of politics and the press in Nigeria before looking at the defining features of the trial itself. The chapter examines how the trial was presented in the press and the readerly engagement that the press sought to foster. The chapter concludes by reflecting on the larger significance of the trial and its coverage in the media at the dawn of Nigeria’s first Republic.Less

This chapter addresses fundamental vector fields. The concept of a connection on a principal bundle is essential in the construction of the Cartan model. To define a connection on a principal bundle, one first needs to define the fundamental vector fields. When a Lie group acts smoothly on a manifold, every element of the Lie algebra of the Lie group generates a vector field on the manifold called a fundamental vector field. On a principal bundle, the fundamental vectors are precisely the vertical tangent vectors. In general, there is a relation between zeros of fundamental vector fields and fixed points of the group action. Unless specified otherwise (such as on a principal bundle), a group action is assumed to be a left action.Less

Much of the work of aid agencies aims to prevent threats to life, rather than to save lives. And even when an aid agency’s activity does save life, it might be doubted whether my contribution to an agency’s pool of funds will itself benefit anyone significantly. However, whether or not that is true, an argument from the life-saving analogy will still support a collective requirement of beneficence on us as a group; and fairness will require me to contribute to discharging that requirement. The collective activity to which I should contribute includes both preventing threats and saving lives.Less

The chapters presented in this book examine the fast-growing compensation culture and the consequential pressure on courts to widen the range of situations in which individuals can claim damages from the State. Within domestic legal systems, there has been a considerable extension of tortious liability which is impinging on the State and its resources. The chapters address statutory and administrative compensation, and examine the influence of group actions and of globalization. Pressure on domestic legal systems has been increased by transnational courts, notably the Court of Human Rights and the European Court of Justice. This book argues that this trend towards judicialization is undesirable, and that greater use should be made of extrajudicial remedies. It contends that the issue of compensation is too important to be left to the courts.Less

The chapter begins with a discussion of circle actions and their relation to 2-sphere bundles. It continues with a section on general Hamiltonian group actions and moment maps, then proceeds to discuss various explicit examples in both finite and infinite dimensions, and introduces the Marsden–Weinstein quotient, together with new examples that explain its relation to the construction of generating functions for Lagrangians. Further sections give a proof of the Atiyah–Guillemin–Sternberg convexity theorem about the image of the moment map in the case of torus actions, and use equivariant cohomology to prove the Duistermaat–Heckman localization formula for circle actions. It closes with an overview of geometric invariant theory which grows out of the interplay between the actions of a real Lie group and its complexification.Less

This chapter contains the text of a 1989 response to Roger Scruton's philosophical paper ‘Corporate Persons’ (summarized in the endnote) emphasizes that the paradigm of personhood is the persisting and organic unity, identity and wholeness of human individuals. This is epistemologically prior to corporate personality or group identity, which is well accounted for by Aquinas in terms of group action, which in turn is to be understood by reference to proposals for action that are held out to members of the group as a plan for coordinating their acts as participation in the group's act(s). The impossibility of setting up a nuclear deterrent as a group bluff (even if the President who would activate it is bluffing) is again underlined.Less

This chapter considers groups acting on trees. It examines which groups act on which spaces and, if a group does act on a space, what it says about the group. These spaces are called trees—that is, connected graphs without cycles. A group action on a tree is free if no nontrivial element of the group preserves any vertex or any edge of the tree. The chapter first presents the theorem stating that: If a group G acts freely on a tree, then G is a free group. The condition that G is free is equivalent to the condition that G acts freely on a tree. The discussion then turns to the Farey tree and shows how to construct the Farey complex using the Farey graph. The chapter concludes by describing free and non-free actions on trees. Exercises and research projects are included.Less

This chapter discusses how those affected by a disaster often form an extraordinary common bond. Self-help support and action group members say that only with others from 'their' disaster can they open up completely, without fear of judgement, about the most difficult aspects of their experience. The examples in this chapter illustrate the kinds of support groups that grew out of those disasters of the 1980s, including the King's Cross Families Action Group, the Herald Families Association, the UK Families Flight 103, the Marchioness Action Group, the Stairway to Heaven Memorial Trust, and the MV Derbyshire Families Association. There are a number of different options for the structure of family and survivor groups in terms of membership, legal status, and management. Some groups have set up unincorporated associations, while a few have chosen to apply for charitable status. Ultimately, representatives from the groups of the 1980s, as well as individual survivors and bereaved people, went on to form, join, and develop Disaster Action.Less

This chapter examines how bicultural skills training might be used within prevention programs to help Latino immigrant families cope with acculturation stress. In particular, it describes the Entre Dos Mundos/Between Two Worlds bicultural skills training model designed to help Latino families adjust to life in the United States and avoid the stress and problems associated with assimilation. The chapter begins with an overview of acculturation-based prevention and intervention programs as well as bicultural skills training before turning to the Entre Dos Mundos/Between Two Worlds bicultural skills training model. It explains Entre Dos Mundos's theoretical background and its key concepts, including action-oriented groups that use a variety of psychodrama techniques such as role reversal, doubling, mirroring, and empty chair. It also discusses the results of an experimental trial of Entre Dos Mundos and concludes with an assessment of how the health and well-being of immigrant families are influenced by ethnic identity and familism, bicultural identity integration, and parent-adolescent cultural conflict and discrimination experiences.Less

This chapter discusses the notion of space, first by explaining what it means for a group to be a group of symmetries of a geometric object. This is the idea of group action, and some examples are given. The chapter proceeds by defining, for any group G, the Cayley graph of G and shows that the symmetric group of of this graph is precisely the group G. It then introduces metric spaces, which formalize the notion of a geometric object, and highlights numerous metric spaces that groups can act on. It also demonstrates that groups themselves are metric spaces; in other words, groups themselves can be thought of as geometric objects. The chapter concludes by using these ideas to frame the motivating questions of geometric group theory. Exercises relevant to each idea are included.Less

This chapter focuses on the ends of a group. It first constructs a group action on the Cantor set and creates a free group from bijections of the Cantor set before showing how the idea of trying to understand what is happening at infinity for an infinite group is captured by the phrase “the ends of a group.” It then explores the notion of ends in the context of infinite graphs and presents examples that provide some insight into the number of ends of groups. It also looks at semidirect products and demonstrates how to calculate the number of ends of the braid groups before moving beyond the process of counting the ends of a group, taking into account the ends of the 4-valent tree. The discussion includes exercises and research projects.Less
