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.

"This book presents a distinctive version of a contractarian approach to law and justice. The work argues that law and justice are social norms that arise from a process of social evolution, and are binding only if and to the extent that they are mutually beneficial. It explicitly rejects accounts of law and justice that are based on morality, on the basis that morality itself is only legitimately founded on mutual advantage, But it also rejects most existing versions of contractarianism, (...) which are based on ideas of hypothetical agreements by rational contractors, in favour of an approach that is based on actually existing social norms, but advocates critically examining these norms and discarding those that are not truly mutually beneficial. The first half of the book develops the approach, while the second half explores some of its implications for law. It argues for a left-libertarian approach to property, an approach largely based on the common law of tort, contract and criminal law, and a rejection of most statutory law, which is based not on mutual advantage but rather on benefiting some at the expense of others. However, it ultimately recognises that there are those who want a more extensive state than this approach allows, and advocates a strong form of federalism to allow this, provided robust exit rights are provided"--.

The aim of this study was to explore neonatal nurses’and mothers of preterm infants’experiences of daily challenges. Interviews took place asking for good, bad and challenging experiences. Data were analysed using qualitative content analysis and findings were clustered in two categories: good and challenging experiences, each containing three themes. The good experiences were: managing with success as a nurse, small things matter for mothers, and a good day anyhow for mothers and nurses. The challenging experiences were: mothering in public, being (...) pulled between responsibilities, and adverse things stick under the nurses’skin. The study shows that small daily clinical matters become big issues and could lead to moral distress, and that nurses integrate ethics of justice and ethics of care while mothers are concerned about health and well-being of their specific infant only. The challenge for nursing to integrate fairness and sensitive care in family-oriented neonatal care is discussed. (shrink)

The vexed question of the exact significance of the name of Mavortius in the old Putean MS. of Prudentius has again been called into court in the recent discussions of the Mavortian recension of Horace, and is fully treated in Dr. Bick's Horazkritik seit 1880, pp. 31–35. As Dr. Bick has done me the honour of subjecting my former articles on the question to his criticism, I feel called upon to say something in defence of the view I maintained. I (...) willingly grant him that perhaps I laid too strong a stress on the connection of the question with Horatian criticism; but I do so, I fear, not as a convert to his arguments in favour of the view that Put. is merely a copy of a MS. that had Mavortius' autograph written in it, and that therefore that name is part of a lost subscriptio, but precisely for the contrary reason, that I consider I was too much influenced by former advocates of that view. That there is no ground for assuming the name to be part of a lost subscriptio I am more than ever convinced, and my object here is to endeavour to show that the whole argument based on a false premise.

I venture to call the attention of classical scholars to two legends about Roman Emperors gleaned amid the arid waste of theological nonsense which passed for literature among the Copts, in the hope that they may have better luck than I have had in tracing them to some classical source. The first is taken from MS. Par. Copte 131, fol. 40, a single leaf of what seems to be a geographical and historical encyclopaedia.1 The writer who is treating in a (...) very discursive way of Ethiopia, states that Nero or Domitian—a strange pair to run in double harness—caused an island in the Red Sea to be watered with oil. The description of that island is mixed up with a mention of the original divisions of the Indians—a term which as usual in early days embraces both Indians and Ethiopians,—and their subsequent changes; and as that too may be of interest to students of ancient geography, I will translate the passage in full.

I DO not think that it is at all generally known that among the Egyptian antiquities given by Grant Bey to the Museum at Aberdeen there are a considerable number of papyrus fragments, Greek, Coptic,1 Hieratic, Demotic, and even Latin and Arabic, which except for an inspection by Prof. Sayce and a passing visit of Dr. Grenfell have up till now been left unexamined. That indeed is my only reason for trespassing in a branch of Palaeography with which I am (...) quite unfamiliar; and it is in the hope of inciting some experienced papyrologist to turn his attention to them that I publish the following fragments. In the case of the Greek fragments lack of time combined with a mistrust of my powers of deciphering the more illegible non-literary hands forbade me do more than select the most promising literary fragments. Among these Homer naturally predominates; but the gem of the collection is a lyric fragment, which may fairly certainly be ascribed to Alcaeus, though Dr. Grenfell who first noticed it attributed it to Sappho. A fragment of Demosthenes, a fragment of Dioscorides, and a vellum fragment of a Latin Bible, were the only others which I succeeded in identifying; but these, with the few tragic, comic, and medical fragments which I also reproduce, are, I think, first-fruits sufficient to show that the crop would not be barren, if it found a competent gleaner.

John Paul II’s encyclical Veritatis Splendor lists several objections to the theological concept of fundamental option. This article summarizes that concept, primarily as presented by Josef Fuchs. It then locates the concept, as Fuchs did, in the overarching theological anthropology of Karl Rahner, which is discussed at length. The objections of the encyclical are then engaged. In some cases, it is shown, the encyclical misunderstands fundamental option. In other cases, its rejection of the idea seems to entail rejection also of (...) traditional Catholic doctrines. All this leads to concluding reflections in which fundamental option is evaluated in terms of its cogency, adequacy, usefulness, and necessity for a contemporary Christian anthropology. (shrink)

The systemic role of corruption and its link to low human development is explored. The extractive resource industry is presented as anarena where conditions for corruption—monopoly and discretion without accountability—are especially intense. Corruption is maintainedby a self-reinforcing cycle. Multiple stakeholders are involved in the maintenance of and/or opposition to the cycle: investing corporations, host country regimes and officials, inter-governmental bodies like the OECD, industry associations, non-governmental organization (NGO) watchdogs like Transparency International, and international agencies facilitating global investment like the World (...) Bank. Complementarity of interests between the demand and supply sides provides strong incentives for entrenched players to maintain corruptive relationships, to protect past gains and sustain current ones. Compulsory international regulation, maximum transparency, effective detection, and enforcement are recommended to enhance accountability, thereby reversing the cycle. It is also necessary to create a corporate culture built on integrity, if regulation itself is to succeed. (shrink)

DEATH is one of the central themes of existentialist writing. This is to be expected since the focal point of all its reflection is human existence. Existentialism explores the innermost depths of experienced selfhood. Inevitably, the authentic self must face the problem of man’s origin and destiny or, in Heideggerian terms, the beginning and ending of his Being-in-the-world. Death is a profoundly human problem, inseparably bound up with the psychological and ontological structure of the human mode of being or Dasein.

The ongoing debate on the ethics of using artificial intelligence (AI) in military contexts has been negatively impacted by the predominant focus on the use of lethal autonomous weapon systems (LAWS) in war. However, AI technologies have a considerably broader scope and present opportunities for decision support optimization across the entire spectrum of the military decision-making process (MDMP). These opportunities cannot be ignored. Instead of mainly focusing on the risks of the use of AI in target engagement, the debate about (...) responsible AI should (i) concern each step in the MDMP, and (ii) take ethical considerations and enhanced performance in military operations into account. A characterization of the debate on responsible AI in the military, considering both machine and human weaknesses and strengths, is provided in this paper. We present inroads into the improvement of the MDMP, and thus military operations, through the use of AI for decision support, taking each quadrant of this characterization into account. (shrink)

One of the central issue of developmental biology concerns the molecular mechanisms whereby a multipotent cell gives rise to distinct differentiated progeny. Differences between specialised cell types reflect variations in their patterns of gene expression. The regulation of transcription initiation is an important control point for gene expression and it is, therefore, not surprising that transcription factors play a pivotal role in mammalian development and differentiation.Haemopoiesis offers a uniquely tractable system for the study of lineage commitment and differentiation. The importance (...) of transcription factor in the normal regulation of haemopoiesis is underlined by the frequency with which transcription factors are targeted by leukaemogenic mutations. Studies of the function and regulation of haemopoietic transcription factors, especially those expressed in lineage‐restricted patterns, should greatly increase our understanding of the molecular control of haemopoiesis. In this review we have focused on insights provided by recent studies of the GATA and SCL proteins. (shrink)
