This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1793 edition. Excerpt: ... error in the altitude of an object near the meridian may produce a considerable error in the apparent time; and because the altitude of a star cannot always be so accurately observed as is necessary for establishing the apparent time; nor can the time, inferred from the Moon's altitude, be depended on, unless its declination and right ascension are reduced to the time of observation, by applying the equation of second difference--it therefore seems most eligible to use the Sun for this purpose. Hence, if this object is too near the meridian at the time of observation of the distance, it becomes necessary to observe its altitude, when in a more proper situation, either previous, or subsequent thereto. Hence the error of the watch will be known, which being applied to the time of observation of the distance, will give the apparent time of observation, agreeable to the meridian for which this error was determined. Or, if the change of longitude in time, between the meridians of the places where the observations were made for ascertaining the time and longitude, be applied to the above found apparent time, by addition or subtraction, according as the ship's course made good has been in the eastern or western quarter, the apparent time will hence be known, for the meridian of the place where the observations were made for determining the longitude. If the watch gains or loses considerably, allowance must be made for its rate in the above interval. October 17, 1786, in latitude 360 12' S. and longitude, by account, 480 15'W. the following observations were taken in order to determine the error of the watch, the height of the eye being 17 feet. Time Towards noon, the following observations were made, the height of the eye being 16 feet....

Bridging environmental and Indigenous studies and drawing on critical geography, spatial theory, new materialist theory, and decolonizing theory, this dynamic volume examines the sometimes overlooked significance of place in social science research. There are often important divergences and even competing logics at work in these areas of research, some which may indeed be incommensurable. This volume explores how researchers around the globe are coming to terms - both theoretically and practically - with place in the context of settler colonialism, globalization, and environmental degradation. Tuck and McKenzie outline a trajectory of critical place inquiry that not only furthers empirical knowledge, but ethically imagines new possibilities for collaboration and action. Critical place inquiry can involve a range of research methodologies; this volume argues that what matters is how the chosen methodology engages conceptually with place in order to mobilize methods that enable data collection and analyses that address place explicitly and politically. Unlike other approaches that attempt to superficially tag on Indigenous concerns, decolonizing conceptualizations of land and place and Indigenous methods are central, not peripheral, to practices of critical place inquiry.

This guide introduces the science of crime mapping to police officers, crime analysts, & other people interested in visualizing crime data through the medium of maps. The guide is made up of examples with the words draped around them. Crime analysts & researchers from across the U.S. & from Canada & the United Kingdom have contributed. The guide takes a broad approach addressing the kinds of questions crime mapping can answer & how, in general terms, it can answer them. Presumably most readers will be working in law enforcement agencies. The material is designed primarily for those who know little or nothing about mapping crime & who are motivated to learn more. Color maps.

An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.

La diversidad biológica es fruto de la interacción entre numerosas especies, ya sean marinas, vegetales o animales, a la par que de los muchos factores limitantes que caracterizan el medio que habitan. El análisis multivariante utiliza las relaciones entre diferentes variables para ordenar los objetos de estudio según sus propiedades colectivas y luego clasificarlos; es decir, agrupar especies o ecosistemas en distintas clases compuestas cada una por entidades con propiedades parecidas. El fin último es relacionar la variabilidad biológica observada con las correspondientes características medioambientales. Multivariate Analysis of Ecological Data explica de manera completa y estructurada cómo analizar e interpretar los datos ecológicos observados sobre múltiples variables, tanto biológicos como medioambientales. Tras una introducción general a los datos ecológicos multivariantes y la metodología estadística, se abordan en capítulos específicos, métodos como aglomeración (clustering), regresión, biplots, escalado multidimensional, análisis de correspondencias (simple y canónico) y análisis log-ratio, con atención también a sus problemas de modelado y aspectos inferenciales. El libro plantea una serie de aplicaciones a datos reales derivados de investigaciones ecológicas, además de dos casos detallados que llevan al lector a apreciar los retos de análisis, interpretación y comunicación inherentes a los estudios a gran escala y los diseños complejos.

Society today may be more vulnerable to global-scale, long-term, climate change than ever before. Even without any human influence, past records show that climate can be expected to continue to undergo considerable change over decades to centuries. Measures for adaption and mitigation will call for policy decisions based on a sound scientific foundation. Better understanding and prediction of climate variations can be achieved most efficiently through a nationally recognized "dec-cen" science plan. This book articulates the scientific issues that must be addressed to advance us efficiently toward that understanding and outlines the data collection and modeling needed.

The goals of the second volume of the AHDR – Arctic Human Development Report: Regional Processes and Global Linkages – are to provide an update to the first AHDR (2004) in terms of an assessment of the state of Arctic human development; to highlight the major trends and changes unfolding related to the various issues and thematic areas of human development in the Arctic over the past decade; and, based on this assessment, to identify policy relevant conclusions and key gaps in knowledge, new and emerging Arctic success stories. The production of AHDR-II on the tenth anniversary of the first AHDR makes it possible to move beyond the baseline assessment to make valuable comparisons and contrasts across a decade of persistent and rapid change in the North. It addresses critical issues and emerging challenges in Arctic living conditions, quality of life in the North, global change impacts and adaptation, and Indigenous livelihoods. The assessment contributes to our understanding of the interplay and consequences of physical and social change processes affecting Arctic residents’ quality of life, at both the regional and global scales. It shows that the Arctic is not a homogenous region. Impacts of globalization and environmental change differ within and between regions, between Indigenous and non-Indigenous northerners, between genders and along other axes.

Rising densities of human settlements, migration and transport to reduce distances to market, and specialization and trade facilitated by fewer international divisions are central to economic development. The transformations along these three dimensions density, distance, and division are most noticeable in North America, Western Europe, and Japan, but countries in Asia and Eastern Europe are changing in ways similar in scope and speed. 'World Development Report 2009: Reshaping Economic Geography' concludes that these spatial transformations are essential, and should be encouraged. The conclusion is not without controversy. Slum-dwellers now number a billion, but the rush to cities continues. Globalization is believed to benefit many, but not the billion people living in lagging areas of developing nations. High poverty and mortality persist among the world's 'bottom billion', while others grow wealthier and live longer lives. Concern for these three billion often comes with the prescription that growth must be made spatially balanced. The WDR has a different message: economic growth is seldom balanced, and efforts to spread it out prematurely will jeopardize progress. The Report: documents how production becomes more concentrated spatially as economies grow. proposes economic integration as the principle for promoting successful spatial transformations. revisits the debates on urbanization, territorial development, and regional integration and shows how today's developers can reshape economic geography.

This open access book not only describes the challenges of climate disruption, but also presents solutions. The challenges described include air pollution, climate change, extreme weather, and related health impacts that range from heat stress, vector-borne diseases, food and water insecurity and chronic diseases to malnutrition and mental well-being. The influence of humans on climate change has been established through extensive published evidence and reports. However, the connections between climate change, the health of the planet and the impact on human health have not received the same level of attention. Therefore, the global focus on the public health impacts of climate change is a relatively recent area of interest. This focus is timely since scientists have concluded that changes in climate have led to new weather extremes such as floods, storms, heat waves, droughts and fires, in turn leading to more than 600,000 deaths and the displacement of nearly 4 billion people in the last 20 years. Previous work on the health impacts of climate change was limited mostly to epidemiologic approaches and outcomes and focused less on multidisciplinary, multi-faceted collaborations between physical scientists, public health researchers and policy makers. Further, there was little attention paid to faith-based and ethical approaches to the problem. The solutions and actions we explore in this book engage diverse sectors of civil society, faith leadership, and political leadership, all oriented by ethics, advocacy, and policy with a special focus on poor and vulnerable populations. The book highlights areas we think will resonate broadly with the public, faith leaders, researchers and students across disciplines including the humanities, and policy makers.
