Opposite Poles presents a fascinating and complex portrait of ethnic life in America. The focus is Chicago Polonia, the largest Polish community outside of Warsaw. During the 1980s a new cohort of Polish immigrants from communist Poland, including many refugees from the Solidarity movement, joined the Polish American ethnics already settled in Chicago. The two groups shared an ancestral homeland, social space in Chicago, and the common goal of wanting to see Poland become an independent noncommunist nation. These common factors made the groups believe they ought to work together and help each other; but they were more often at opposite poles. The specious solidarity led to contentious conflicts as the groups competed for political and cultural ownership of the community. Erdmans's dramatic account of intracommunity conflict demonstrates the importance of distinguishing between immigrants and ethnics in American ethnic studies. Drawing upon interviews, participant observation in the field, surveys and Polish community press accounts, she describes the social differences between the two groups that frustrated unified collective action. We often think of ethnic and racial communities as monolithic, but the heterogeneity within Polish Chicago is by no means unique. Today in the United States new Chinese, Israeli, Haitian, Caribbean, and Mexican immigrants negotiate their identities within the context of the established identities of Asians, Jews, Blacks, and Chicanos. Opposite Poles shows that while common ancestral heritage creates the potential for ethnic allegiance, it is not a sufficient condition for collective action.

Life scientists are increasingly drawn to the study of comparative evolutionary biology. Insect Development and Evolution is the first synthesis of knowledge of insect development within an evolutionary framework and the first to survey the genetic, molecular, and whole organism literature. Bruce S. Heming provides a detailed introduction to the embryonic and postembryonic development of insects. Topics include:* reproductive systems,* male and female gametogenesis,* sperm transfer and use,* fertilization,* sex determination,* parthenogenesis,* embryogenesis,* postembryogenesis,* hormones,* and the role of ontogeny in insect evolution.Summaries for each of these topics cover structural events; comparative aspects (inserted on a phylogeny of the insect orders); and hormonal, genetic, and molecular causal analyses.Insect Development and Evolution treats examples throughout the hexapods with frequent reference to the evolution and development of other invertebrates. It also compares insects to vertebrates and places insect development into context with fossil evidence and earth history. Heming's book will become an essential tool for students and teachers of entomology. It will also interest insect systematists and paleontologists, insect behavioral ecologists, insect pathologists, applied entomologists, developmental and invertebrate biologists, and all scientists who use Drosophila as a model organism.

This book is primarily designed for students preparing for various competitive exam- inations. It will also be helpful for those preparing for midterm exams in schools or universities. The aim of this book is twofold: first, to help the students preparing for competitive examinations, seeking admission to universities or schools, or prepare for job interviews. Second, it will also be helpful for those studying TAJIKISTAN. This book contains more than 36 questions from the core areas of TAJIKISTAN. The questions are grouped chapter-wise. There are total 1 chapters, 3 sections and 36+ MCQ with answers. This reference book provides a single source for multiple choice questions and answers in TAJIKISTAN. It is intended for students as well as for developers and researchers in the field. This book is highly useful for faculties and students. One can use this book as a study guide, knowledge test questions bank, practice test kit, quiz book, trivia questions . . . etc. The strategy used in this book is the same as that which mothers and grandmothers have been using for ages to induce kids in the family to sip more soup (or some other nutritious drink). The children are told that some cherries (their favourite noo- dles or cherries ) are hidden somewhere in the bowl, and that serves as an incentive for drinking the soup. In joint families, by the time the children are old enough to know the trick played by their grandma, there is usually another group of kids ready to fall for it! They excite the kids, but the real nutrition lies not in the noodles but in the soup. The problems given in this book are like those noodles/cherries while solving all these problems are nutritious soup. Now it is your choice to drink the nutritious soups or not!!!.

Looking Into the Earth comprehensively describes the principles and applications of both 'global' and 'exploration' geophysics on all scales. It forms an introduction to geophysics suitable for those who do not necessarily intend to become professional geophysicists, including geologists, civil engineers, environmental scientists, and field archaeologists. The book is organised into two parts: Part 1 describes the geophysical methods, while Part 2 illustrates their use in a number of extended case histories. Mathematical and physical principles are introduced at an elementary level, and then developed as necessary. Student questions and exercises are included at the end of each chapter. The book is aimed primarily at introductory and intermediate university students taking courses in geology, earth science, environmental science, and engineering. It will also form an excellent introductory textbook in geophysics departments, and will help practising geologists, archaeologists and engineers understand what geophysics can offer their work.
