The long-awaited revision of the industry standard on phylogenetics Since the publication of the first edition of this landmark volume more than twenty-five years ago, phylogenetic systematics has taken its place as the dominant paradigm of systematic biology. It has profoundly influenced the way scientists study evolution, and has seen many theoretical and technical advances as the field has continued to grow. It goes almost without saying that the next twenty-five years of phylogenetic research will prove as fascinating as the (...) first, with many exciting developments yet to come. This new edition of Phylogenetics captures the very essence of this rapidly evolving discipline. Written for the practicing systematist and phylogeneticist, it addresses both the philosophical and technical issues of the field, as well as surveys general practices in taxonomy. Major sections of the book deal with the nature of species and higher taxa, homology and characters, trees and tree graphs, and biogeography—the purpose being to develop biologically relevant species, character, tree, and biogeographic concepts that can be applied fruitfully to phylogenetics. The book then turns its focus to phylogenetic trees, including an in-depth guide to tree-building algorithms. Additional coverage includes: Parsimony and parsimony analysis Parametric phylogenetics including maximum likelihood and Bayesian approaches Phylogenetic classification Critiques of evolutionary taxonomy, phenetics, and transformed cladistics Specimen selection, field collecting, and curating Systematic publication and the rules of nomenclature Providing a thorough synthesis of the field, this important update to Phylogenetics is essential for students and researchers in the areas of evolutionary biology, molecular evolution, genetics and evolutionary genetics, paleontology, physical anthropology, and zoology.

El propósito de este texto es ofrecer una visión general de la relación entre nación e historia en los debates que se generaron por parte de los historiadores y otros intelectuales de las ciencias sociales a finales del siglo XIX y durante gran parte del siglo XX. La reflexión central que se plantea consiste entonces en estudiar y mostrar cómo al mismo tiempo que las naciones modernas eran objeto de un proceso de redefinición política, en el escenario intelectual de las (...) ciencias sociales, y en particular de los historiadores, fueron apareciendo también un conjunto de debates y obras que intentaban problematizar y someter a consideración las relaciones que pretendían establecerse entre la nación y la historia como un elemento que las justificaba.

What is the nature of the intellectual enterprise - general equilibrium analysis - that so many economists regard as the centerpiece of their discipline? In this book, Roy Weintraub considers both the modern history of the analysis, and the methodological puzzles that it, and mathematical economic theory in general, pose. Professor Weintraub argues that previous writings on the history and method of general equilibrium theory have been curiously biased and misleading. He provides a clear and careful presentation of the development (...) of the theory from the 1930s through to the Arrow-Debreu work of the 1950s. This historical analysis is the centre of the book: a case study which permits the author to justify the status of general equilibrium theory in economics and the activity in which economic theorists engage. He argues that previous methodological investigations have been distorted by their use of inappropriate models taken from the philosophy of science that were developed to appraise work in the physical sciences.

Today, economic theory is a mathematical theory, but that was not always the case. Major changes in the ways economists presented their arguments to one another occurred between the late 1930s and the early 1950s; over that period the discipline became mathematized. Professor Weintraub, a noted scholar of the modern history of economic thought, argues that those changes were not merely cosmetic: The mathematical forms of the arguments significantly altered the substance of the arguments. Stabilizing Dynamics is particularly concerned with (...) the ways in which the rich and confusing talk of the 1930s evolved, over a fifteen-year period, into technical analysis of some mathematical structures. The author describes the context for the history of that change, locating it in the broader intellectual currents, and shows how the history of modern economics can be seen as a confluence of several disparate traditions. Historiographically, this book offers one of the first constructivist accounts of modern economic analysis. (shrink)

Studies examining the ways in which the training of engineers and scientists shapes their research strategies and scientific identities.

Though merely an essay, I challenge you, gentle reader, by attempting to demonstrate that my own words are not fundamentally different from the conscious thoughts in your own mind: I thus claim to have consciousness and qualia.

The author of this study has a single-minded goal--the construction of a social ethic for the Hispanic Pentecostal Church in America that both coheres with the ...

The public expects members of the medical profession to conduct themselves according to the terms of the Hippocratic oath, yet few physicians and virtually no laypersons know what is in that oath. For the oath to reach beyond its symbolic importance, ethical conduct must be learned and practised. There are many texts on the practice of medicine, surgery and all of the related disciplines, yet one is hard pressed to find anything on ethical practice in any of them. Scholarly texts (...) on ethics tend to deal with the landmark issues and dilemmas that have occurred within particular jurisdictions or religions. This book is intended as a student-friendly text that seeks not to turn students into ethics scholars but to provide them with a practical guide to ethical conduct in everyday medical practice. and discussion are provided for each of the following areas: Ethical Practices in Health Care Law and Ethics Rights of Patients and Responsibilities of Health-Care Providers The Rights of Health-Care Professionals The Duty of Care Confidentiality Consent to Treatment Life and Death Research Ethics Ethics in Public Health Practice Ethical Practice in Everyday Health Care is useful, practical and student friendly. The exercises and discussions will stimulate thought about ethical conduct and help students to develop and translate ethical principles into their daily practice as health-care workers. Dr Walrond offers a ready and concise source of information for medical students on ethical issues. The text is simple, comprehensive and factual, addressing issues encountered in everyday medical practices. Case studies provide practical illustrations of complex ethical issues. (shrink)

Concerns for safety and security as South Africa’s hosting of 2010 FIFA World Cup draws nearer highlight the degree to which South Africa’s reputation for a relatively peaceful transition from Apartheid has been replaced by its reputation for violent crime. Its transition, and the peacebuilding efforts that followed it, are not completely unrelated to its current high levels of violent crime. In fact, this article argues that there were a number of issues South Africa’s peacebuilding process failed to address that (...) are relevant to the country’s violent crime situation. A significant reason for this failure was an inability or unwillingness to engage the full spectrum of Apartheid’s violence with equal rigour. Apartheid inflicted structural violence, through its racially oppressive laws, as well as physical violence, through enforcing its laws and suppressing its opposition, on the people of South Africa. Peacebuilding in South Africa primarily focused on Apartheid’s physical violence. Through the work of the Truth and Reconciliation Commission, the focus was narrowed down further to physical political violence. Due to this narrow focus, it did not attend effectively to non-political violence – which includes gender-based violence, the esteem violence had attained during and due to Apartheid, disarming the country of illegal firearms, and narrowing the income gap between the country’s rich and poor. While South Africa proudly claims ownership of its conflict resolution and peacebuilding processes, it still emulated predominant models of building peace through liberal democracy and a market economy. These models have been drawn from Western success stories in diminishing interstate conflict, while South Africa is a developing country that was recovering from an intrastate conflict. Pursuing these models has had benefits for South Africa, but not in many of the ways it needed in order to effectively prevent a surge in criminal violence in the wake of Apartheid. (shrink)

This is the first full-length survey of current work which examines the compatibility of microeconomics and macroeconomics. Its particular distinction is that it makes accessible, to non-specialists, those extensive modern refinements of general equilibrium theory which are linked to macroeconomics and monetary theory. Part I traces the development and interlocking nature of two scientific research prgrams, macroeconomics and neo-Walrasian analysis. The five chapters in this part examine general equilibrium theory, Keynes' contribution, the 'neoclassical synthesis', and the Clower–Leijonhufvud contributions to questions (...) of systemic coordination. The four chapters of Part II place recent work on the micro-foundations of macroeconomics within a taxonomic scheme of Walrasian equilibrium, Walrasian disequilibrium, Edgeworthian equilibrium, and Edgeworthian disequilibrium. Part III, a single chapter, provides an overview of the subject and ventures some conclusions. (shrink)

J'examine plusieurs sources selon lesquelles Swyneshed (malgré les prétentions d'Angel D'Ors dans ses articles récents) donne une nova responsio en partie sous forme de la règle « On peut nier une proposition conjonctive après avoir concédé ses deux parties. » Je montre que cette nova responsio est liée à un rejet de la règle « Chaque proposition qui suit de l'ensemble de propositions déjà concédées doit être concédée », et j'attribue ce rejet à une théorie selon laquelle une inférence se (...) base sur le rapport logique entre seulement deux propositions. I examine a number of sources according to which Swyneshed (despite the claims made by Angel D'Ors in his recent articles) does give a nova responsio partly in the form of the rule « One can deny a conjunction whose conjuncts have already been granted. » I show that this nova responsio is linked to a rejection of the rule « Every proposition following from a set of propositions which have already been granted must be granted », and I attribute this rejection to a theory whereby an inference is based on the logical relations between just two propositions.
