The subject of this book is the action of permutation groups on sets associated with combinatorial structures. Each chapter deals with a particular structure: groups, geometries, designs, graphs and maps respectively. A unifying theme for the first four chapters is the construction of finite simple groups. In the fifth chapter, a theory of maps on orientable surfaces is developed within a combinatorial framework. This simplifies and extends the existing literature in the field. The book is designed both as a course text and as a reference book for advanced undergraduate and graduate students. A feature is the set of carefully constructed projects, intended to give the reader a deeper understanding of the subject.

The abundance of carefully prepared microdrawings of rock types and textures was a feature that maintained the demand for Harker's 1954 text Petrology for Students as a guide to the study of rocks in thin slices under the microscope. This 1978 successor makes Harker's microdrawings, together with over 60 further ones, available in an original petrographic text, amplifying the coverage to embrace rock types whose importance had increased since Harker's work was published. Three sections cover igneous, sedimentary and metamorphic rocks. The igneous section emphasises the use of chemical and mineralogical characteristics in the description of igneous rocks, whilst the sedimentary section covers each major sediment class, describing how to recognise and interpret individual rock constituents. The metamorphic section summarises metamorphic reconstitution and discusses the metamorphic facies classification. Each section uses the terminology and treatment resulting from specialisation in the

In the seventies the British political system was in deep and growing crisis. The leading political parties appeared unable to offer effective solutions to the major problems which confronted the electorate and the electorate was consequently increasingly alienated from politicians who promised so much and delivered so little. The gap between promise and performance had been a persistent feature of Labour Party politics in particular and with the revival of radicalism within the Labour Party during the 1970s it was the opportune time to re-examine the record of the party and its potential. David Coates offers an important analysis of the Labour Party during this time and its history. He examines the roots of the Party and its development up to 1945 and analyses the performance of the 1945–51 Attlee Governments in depth. He traces developments within the Party in the 1950s and offers one of the first detailed accounts of the performance in office between 1964 and 1970.

Build fluency through oral reading with these colorful scripts! The scripts included in this kit make repeated reading and building fluency an engaging task for early learners by having them act out lively stories! This kit includes eight scripts with leveled roles written at multiple reading levels, making it easy to implement differentiation strategies included in the Teacher's Guide. This feature allows teachers to assign roles to students in a way that best accommodates their individual reading levels. This encourages all students to participate and engage in the same activity, regardless of their current reading ability. All readers can gain confidence and feel successful! By performing these stories together, students will practice important skills like interacting cooperatively, reading aloud, and using expressive voices and gestures. Each script also includes a poem and song to give children additional fluency practice. All of these scripts give students the tools they need to

In his brilliant and tragically brief career, Kenneth Craik anticipated certain ideas which since his death in 1945 have found wide acceptance. As one of the first to realise that machines share with the brain certain principles of functioning, Craik was a pioneer in the development of physiological psychology and cybernetics. Craik published only one complete work of any length, this essay on The Nature of Explanation. Here he considers thought as a term for the conscious working of a highly complex machine, viewing the brain as a calculating machine which can model or parallel external events, a process that is the basic feature of thought and explanation. He applies this view to a number of psychological and philosophical problems (such as paradox and illusion) and suggests possible experiments to test his theory. This book is of interest to those concerned with the concepts of brain and mind.

This is a book about powerful mathematical methods rather than a mere catalogue of the properties of conics. The treatment is elegant and refreshing as well as systematic, and throughout the book the author is concerned to lay the foundations of future work. Consequently (unlike too many textbooks) there is little for the student to unlearn when he goes on to more advanced courses. A valuable feature is the large number of carefully selected and graded problems for solution (about 400 in all). When this book was first published, the reviewer in Science suggested that 'this scholarly work should be supplemented by a similar book on the analytic projective geometry of ordinary space'. His suggestion has since been adopted: and the companion volume, E.A. Maxwell's General Homogenous Coordinates in Space of Three Dimensions is now also available.

政治歸政治，藝術歸藝術？當博物館冠上「國家級」，一切就沒那麼簡單。文物一旦跨出國界，除了美學的交流，更是代表國家軟實力的頂級裝備。 各國館舍之間的文物借展流轉，背後是極其複雜的文化外交與信任角力。為什麼借？為什麼是這件？每一次選擇，既是文化底蘊的展現，也是國家形象的建構；每一次展出，都在國際社會中重新標示自身的位置。 展覽本身，就是一種話語權的實踐。從選件到敘事框架，從標籤文字到展場動線，都可能隱含著特定的歷史視角與政治想像。當我們觀看作品時，也同時被引導進入某種被安排的閱讀方式。藝術從未置身政治之外，政治也是藝術。 這次，就讓我們直擊那些隱藏在展間燈光下，從未停止過的國家級角力；進而理解：當我們先看見自己，其他人才有機會看見我們。 《典藏．古美術》403期（2026年4月號）「國際政治的藝術角力」 簡介影片連結： https://youtube.com/shorts/OTsglJGthnU?feature=share
