  • An analysis of the complex relationship between demographic changes and impacts on the natural-resource base confirms that resource exploitation is occurring not only to meet growing domestic needs but also for other vested interests. Population, together with other major drivers, such as institutions, markets, and technology, will have a very strong bearing on the way in which the rich resources of the Mekong River Basin are developed and distributed in the present and future.

  • When it comes to advocating animal conservation, it is difficult to be convincing without becoming alarmist. The fact is, time is running out for many of the world’s animal species. Habitat loss, introduced species, overexploitation and pollution, all caused by human activities, combine with stochastic factors to place ever-increasing pressure on natural populations (Primack 2002).

  • This is an introductory textbook on mathematical ecology bridging the subdisciplines of population ecology and ecosystem ecology. The expected reader is you: a beginning graduate student, advanced undergraduate student, or someone who thinks of themselves as a student all their lives, with a working knowledge of basic calculus and basic ecology. While this is intended as a stand-alone text, the level is such that once you have read through it, you will be able to read more advanced texts and monographs such as Ågren and Bosatta (1998) and Kot (2001) with greater depth.

  • This chapter aims to clarify the concept of population balance model or population balance equation, terms that are used almost interchangeably in this book. This is followed by a short narrative of the strengths and weaknesses of these models. 1.1 What Are Population Balance Models? Population balance is not a well-defined concept in science and engineering, but means slightly different things to different people.

  • The NCRP has long recognized the need for a clear assessment of the magnitude of doses from various sources of radiation to which the population of the U.S. is exposed. In anticipation of the need to gather data for input into this process, five assessment committees, each addressing a different source category, were established. NCRP reports assessing exposures from natural background, consumer products, nuclear power generation, and diagnostic medical radiation have been published (NCRP, 1987a,b,c,d, NCRP, 1989)....

  • This timely book describes the issues that compel us to craft a new social agenda for Latin America, which now needs to incorporate the challenges of the growing aging population. The region has improved the efficiency of its social policies, but we have a long road ahead and we need to continue innovating. Governments and the private sector must learn to balance the demands posed by a rapidly growing population of seniors while continuing to invest in the education of our youth and the needs of the poor. This book should be of interest to anyone with a serious interest...

  • Population geneticists study the genetic composition and variability of natural populations as well as the theories that explain this variability in terms of natural selection, mutation, recombination, genetic drift and gene flow. Population genetics was first developed among eukaryotes in an attempt to reconcile Darwin’s theory of evolution by natural selection and Mendelian genetics. When Darwin postulated that natural selection is the main force of evolutionary change, a great controversy was created.

  • In this paper we give an overview of the Knowledge Base Population (KBP) track at the 2010 Text Analysis Conference. The main goal of KBP is to promote research in discovering facts about entities and augmenting a knowledge base (KB) with these facts. This is done through two tasks, Entity Linking – linking names in context to entities in the KB – and Slot Filling – adding information about an entity to the KB.

  • The present text introduces the use of population balances in the context of batch wet granulation and coating systems and it reviews the latest achievements and proposals in the scientific literature in this field. The nature and framework of population balance theory are highlighted and one-dimensional population balances are introduced from scratch. This may seems tedious at first but the derivation of even the simplest population balances is nevertheless not an easy task, and it is in fact difficult to find complete derivations elsewhere in literature.

  • We present a weakly supervised approach to automatic Ontology Population from text and compare it with other two unsupervised approaches. In our experiments we populate a part of our ontology of Named Entities. We considered two high level categories - geographical locations and person names and ten sub-classes for each category. For each sub-class, from a list of training examples and a syntactically parsed corpus, we automatically learn a syntactic model - a set of weighted syntactic features, i.e.
