The acclaimed social psychologist offers an insider’s look at his research and groundbreaking findings on stereotypes and identity. Claude M. Steele, who has been called “one of the few great social psychologists,” offers a vivid first-person account of the research that supports his groundbreaking conclusions on stereotypes and identity. He sheds new light on American social phenomena from racial and gender gaps in test scores to the belief in the superior athletic prowess of black men, and lays out a plan for mitigating these “stereotype threats” and reshaping American identities.

National news reports periodically proclaim that American life is lonelier than ever, and new books on the subject with titles like Bowling Alone generate considerable anxiety about the declining quality of Americans' social ties. Still Connected challenges such concerns by asking a simple yet significant question: have Americans' bonds with family and friends changed since the 1970s, and, if so, how? Noted sociologist Claude Fischer examines long-term trends in family ties and friendships and paints an insightful and ultimately reassuring portrait of Americans' personal relationships. Still Connected analyzes forty years of survey research to address whether and how Americans' personal ties have changed—their involvement with relatives, the number of friends they have and their contacts with those friends, the amount of practical and emotional support they are able to count on, and how emotionally tied they feel to these relationships. The book shows that Americans today have fewer relatives than they did forty years ago and that formal gatherings have declined over the decades—at least partially as a result of later marriages and more women in the work force. Yet neither the overall quantity of personal relationships nor, more importantly, the quality of those relationships has diminished. Americans' contact with relatives and friends, as well as their feelings of emotional connectedness, has changed relatively little since the 1970s. Although Americans are marrying later and single people feel lonely, few Americans report being socially isolated and the percentage who do has not really increased. Fischer maintains that this constancy testifies to the value Americans place on family and friends and to their willingness to adapt to changing circumstances in ways that sustain their social connections. For example, children now often have schedules as busy as their parents. Yet today's parents spend more quality time with their children than parents did forty years ago—although less in the form of organized home activities and more in the form of accompanying them to play dates or sports activities. And those family meals at home that seem to be disappearing? While survey research shows that families dine at home together less often, it also shows that they dine out together more often. Americans are fascinated by the quality of their relationships with family and friends and whether these bonds fray or remain stable over time. With so many voices heralding the demise of personal relationships, it's no wonder that confusion on this topic abounds. An engrossing and accessible social history, Still Connected brings a much-needed note of clarity to the discussion. Americans' personal ties, this book assures us, remain strong.
Aquaculture, Resource Use, and the Environment places aquaculture within the larger context of global population growth, increased demand for sustainable, reliable sources of food, and the responsible use of natural resources. Aquaculture production has grown rapidly in recent decades as over-exploitation and environmental degradation have drastically reduced wild fish stocks. As fish production has increased, questions have persisted about the environmental sustainability of current aquaculture practices. Aquaculture, Resource Use, and the Environment is a timely synthesis and analysis of critical issues facing the continued growth and acceptance of aquaculture practices and products. Chapters look at the past, present, and future demands for food, aquaculture production, and tackle key issues ranging from environmental impacts of aquaculture to practical best management practices in aquaculture production. Providing broad coverage of issues that are essential to the continued development of aquaculture production, Aquaculture, Resource Use, and the Environment will be vital resource for anyone involved in the field of aquaculture.
Presented from the viewpoint of the history of mathematics, this book explores both epistemological aspects of Chinese traditional mathematical astronomy and lunisolar calendrical calculations. The following issues are addressed: (1) connections with non-Chinese cultural areas; (2) the possibility or impossibility of using mathematics to predict astronomical phenomena, a question that was constantly raised by the Chinese from antiquity through medieval times; (3) the modes of representation of numbers, and in particular the zero, found in the context of Chinese calendrical calculations; and (4) a detailed analysis of lunisolar calendrical calculations. Fully worked-out examples and comparisons between the results of calculations and the content of Chinese historical calendars from various periods are provided. Traditional Chinese calendrical and mathematical astronomy consists of permanently reformed mathematical procedures designed to predict, but not explain, phenomena pertaining to astronomy and related areas. Yet, despite appearances, models of the mathematical techniques hidden behind this voluminous corpus reveal that they depend on a limited number of clear-cut mathematical structures. Although only a small fraction of these techniques have been fully studied, what is known surprisingly broadens our knowledge of the history of Chinese mathematics. Sinologists interested in the history of Chinese science, and anyone interested in the history of Chinese mathematics, the Chinese calendar, and the history of Chinese mathematical astronomy from its origin (104 BC) to its European reform (AD 1644) will find this book very useful. The present English language edition is a fully revised and updated version of the French original. Even though this is a research monograph in sinology, no particular sinological background is required, although a basic understanding of ‘concrete mathematics’ is needed. From the reviews of the French edition: This is a demanding, rigorous book to read ... worth the concentrated study it requires. The rewards are not only in the details but in the general overview that ...[it] provides. Joseph Dauben, EASTM, 2011 ...first Work in a Western language to turn to for anyone interested in the details of Chinese calendrical computations. Benno Van Dalen, ISIS, 2011 Martzloff’s careful scholarship and his overall look at the calendar beyond astronomical calculations, ..., make this book a most valuable contributions to a field of increasing interest.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 163. The North, with its vast and varied landscapes, sparse population, and cold climate has always challenged its explorers: physically, mentally, logistically, and technically. The scientific community in particular has known such challenges in the past and does so today, especially in light of the projected intensification of climate change at high latitudes. Indeed, there are clear signs that change is already ongoing in many environmental variables: Air temperature and annual precipitation (including snowfall) are increasing in many regions; spring snow cover extent is decreasing; lake and river ice freeze-up dates are occurring later and breakup dates earlier; glaciers are retreating rapidly; permafrost temperatures are increasing and, in many cases, the permafrost is thawing; and sea-ice extent is at record minimums and thinning.
