Circles and Settings: Role Changes of American Women is an original, comprehensive analysis of changing roles of American women at a time of great upheaval and public, as well as social science, commentary. Using a symbolic interactionist framework, with role seen as a set of negotiated relations, Lopata analyses the roles of wife, mother, kin member (daughter, sister, grandmother) homemaker, job holder in different settings, as well as friend, neighbor, volunteer, and activist. This book comprehensively pulls together all the major involvements of American women using both historical and comparative perspectives to show the evolution of these roles over the last century.

Machine Intelligence and Pattern Recognition, Volume 2: Computational Geometry focuses on the operations, processes, methodologies, and approaches involved in computational geometry, including algorithms, polygons, convex hulls, and bucketing techniques. The selection first ponders on optimal parallel algorithms for selection, sorting, and computing convex hulls, simple on-line algorithms for convex polygons, and geometric algorithms that use the furthest-point Voronoi diagram. Discussions focus on algorithms that use the furthest-point Voronoi diagram, intersection of a convex polygon and a halfplane, point insertion, convex hulls and polygons and their representations, and parallel algorithm for selection and computing convex hulls. The text then examines optimal convex decompositions, expected time analysis of algorithms in computational geometry, and practical use of bucketing techniques in computational geometry. The book takes a look at minimum decompositions of polygonal objects, framework for computational morphology, display of visible edges of a set of convex polygons, and implementation study of two algorithms for the minimum spanning circle problem. Topics include rolling algorithm, shape of point sets, and decomposition of rectilinear and simple polygons and polygons with holes. The selection is a valuable source of data for researchers interested in computational geometry.

Swarm intelligence algorithms are a form of nature-based optimization algorithms. Their main inspiration is the cooperative behavior of animals within specific communities. This can be described as simple behaviors of individuals along with the mechanisms for sharing knowledge between them, resulting in the complex behavior of the entire community. Examples of such behavior can be found in ant colonies, bee swarms, schools of fish or bird flocks. Swarm intelligence algorithms are used to solve difficult optimization problems for which there are no exact solving methods or the use of such methods is impossible, e.g. due to unacceptable computational time. This set comprises two volumes: Swarm Intelligence Algorithms: A Tutorial and Swarm Intelligence Algorithms: Modifications and Applications. The first volume thoroughly presents the basics of 24 algorithms selected from the entire family of swarm intelligence algorithms. It contains a detailed explanation of how each algorithm works, along with relevant program codes in Matlab and the C ++ programming language, as well as numerical examples illustrating step-by-step how individual algorithms work. The second volume describes selected modifications of these algorithms and presents their practical applications. This book presents 24 swarm algorithms together with their modifications and practical applications. Each chapter is devoted to one algorithm. It contains a short description along with a pseudo-code showing the various stages of its operation. In addition, each chapter contains a description of selected modifications of the algorithm and shows how it can be used to solve a selected practical problem.

Research on polyhedral manifolds often points to unexpected connections between very distinct aspects of Mathematics and Physics. In particular triangulated manifolds play quite a distinguished role in such settings as Riemann moduli space theory, strings and quantum gravity, topological quantum field theory, condensed matter physics, and critical phenomena. Not only do they provide a natural discrete analogue to the smooth manifolds on which physical theories are typically formulated, but their appearance is rather often a consequence of an underlying structure which naturally calls into play non-trivial aspects of representation theory, of complex analysis and topology in a way which makes manifest the basic geometric structures of the physical interactions involved. Yet, in most of the existing literature, triangulated manifolds are still merely viewed as a convenient discretization of a given physical theory to make it more amenable for numerical treatment. The motivation for these lectures notes is thus to provide an approachable introduction to this topic, emphasizing the conceptual aspects, and probing, through a set of cases studies, the connection between triangulated manifolds and quantum physics to the deepest. This volume addresses applied mathematicians and theoretical physicists working in the field of quantum geometry and its applications.

The volume is devoted to the interaction of modern scientific computation and classical function theory. Many problems in pure and more applied function theory can be tackled using modern computing facilities: numerically as well as in the sense of computer algebra. On the other hand, computer algorithms are often based on complex function theory, and dedicated research on their theoretical foundations can lead to great enhancements in performance. The contributions - original research articles, a survey and a collection of problems - cover a broad range of such problems.

Widowhood in an American City focuses on the roles and lifestyles of urban American widows fifty years of age or older. These women form a segment of two generations of one society; they present a historical instance of people born and brought up under conditions that are not likely to be duplicated. Not only the U.S., but many other countries are undergoing modifications in the degrees and forms of urbanization, industrialization, and social complexity.Helena Znaniecki Lopata argues that the way women re-engage society following the death of a husband is different due to their location in the modern social system. She notes that the trends in social structure are toward increasingly voluntaristic engagement in achieved, functionally oriented social roles that are performed in large groups and contain secondary social relations. The cultural background of many societal members prevents the utilization of most resources of the complex urban world, restricting them to a small social life space, with almost automatically prescribed social relations.Those who argue that the elderly are socially isolated contend that this is a result of the natural process of withdrawal of the person and the society from each other. These arguments focus on those who are isolated or lonely and those who lack the skills, money, health, and transportation for engaging or re-engaging society. Lopata's study indicates that this assumption is false for many widows. If such people are to be helped, a fresh view of the relation between the urban, industrial, and complex modern world and its residents is required, and new action programs must be creatively developed. This is a timely, ground-breaking work that addresses and shatters common myths associated with growing old alone in an urban society.
