Experimental research is commonly held up as the paradigm of "good" science. Although experiment plays many roles in science, its classical role is testing hypotheses in controlled laboratory settings. Historical science is sometimes held to be inferior on the grounds that its hypothesis cannot be tested by controlled laboratory experiments. Using contemporary examples from diverse scientific disciplines, this paper explores differences in practice between historical and experimental research vis-à-vis the testing of hypotheses. It rejects the claim that historical research is (...) epistemically inferior. For as I argue, scientists engage in two very different patterns of evidential reasoning and, although there is overlap, one pattern predominates in historical research and the other pattern predominates in classical experimental research. I show that these different patterns of reasoning are grounded in an objective and remarkably pervasive time asymmetry of nature. (shrink)

The Church-Turing thesis makes a bold claim about the theoretical limits to computation. It is based upon independent analyses of the general notion of an effective procedure proposed by Alan Turing and Alonzo Church in the 1930''s. As originally construed, the thesis applied only to the number theoretic functions; it amounted to the claim that there were no number theoretic functions which couldn''t be computed by a Turing machine but could be computed by means of some other kind of effective (...) procedure. Since that time, however, other interpretations of the thesis have appeared in the literature. In this paper I identify three domains of application which have been claimed for the thesis: (1) the number theoretic functions; (2) all functions; (3) mental and/or physical phenomena. Subsequently, I provide an analysis of our intuitive concept of a procedure which, unlike Turing''s, is based upon ordinary, everyday procedures such as recipes, directions and methods; I call them mundane procedures. I argue that mundane procedures can be said to be effective in the same sense in which Turing machine procedures can be said to be effective. I also argue that mundane procedures differ from Turing machine procedures in a fundamental way, viz., the former, but not the latter, generate causal processes. I apply my analysis to all three of the above mentioned interpretations of the Church-Turing thesis, arguing that the thesis is (i) clearly false under interpretation (3), (ii) false in at least some possible worlds (perhaps even in the actual world) under interpretation (2), and (iii) very much open to question under interpretation (1).

This is a book about the harms of oppression, and about addressing these harms using the resources of liberalism and Kantianism. Its central thesis is that people who are oppressed are bound by the duty of self-respect to resist their own oppression. In it, I defend certain core ideals of the liberal tradition—specifically, the fundamental importance of autonomy and rationality, the intrinsic and inalienable dignity of the individual, and the duty of self-respect—making the case that these ideals are pivotal in (...) both understanding and counteracting oppression. I argue that if we take these ideals seriously then it follows that people who are oppressed have an obligation to themselves to resist their own oppression. (shrink)

Bringing together the latest scientific advances and some of the most enduring subtle philosophical puzzles and problems, this book collects original historical and contemporary sources to explore the wide range of issues surrounding the nature of life. Selections ranging from Aristotle and Descartes to Sagan and Dawkins are organised around four broad themes covering classical discussions of life, the origins and extent of natural life, contemporary artificial life creations and the definition and meaning of 'life' in its most general form. (...) Each section is preceded by an extensive introduction connecting the various ideas discussed in individual chapters and providing helpful background material for understanding them. With its interdisciplinary perspective, this fascinating collection is essential reading for scientists and philosophers interested in astrobiology, synthetic biology and the philosophy of life.

In the technical literature of computer science, the concept of an effective procedure is closely associated with the notion of an instruction that precisely specifies an action. Turing machine instructions are held up as providing paragons of instructions that "precisely describe" or "well define" the actions they prescribe. Numerical algorithms and computer programs are judged effective just insofar as they are thought to be translatable into Turing machine programs. Nontechnical procedures (e.g., recipes, methods) are summarily dismissed as ineffective on the (...) grounds that their instructions lack the requisite precision. But despite the pivotal role played by the notion of a precisely specified instruction in classifying procedures as effective and ineffective, little attention has been paid to the manner in which instructions "precisely specify" the actions they prescribe. It is the purpose of this paper to remedy this defect. The results are startling. The reputed exemplary precision of Turing machine instructions turns out to be a myth. Indeed, the most precise specifications of action are provided not by the procedures of theoretical computer science and mathematics (algorithms) but rather by the nontechnical procedures of everyday life. I close with a discussion of some of the rumifications of these conclusions for understanding and designing concrete computers and their programming languages. (shrink)

This article argues that Thomas Pogge's important theory of global justice does not adequately appreciate the relation between interactional and institutional accounts of human rights, along with the important normative role of care and solidarity in the context of globalization. It also suggests that more attention needs to be given critically to the actions of global corporations and positively to introducing democratic accountability into the institutions of global governance. The article goes on to present an alternative approach to global justice (...) based on a more robust conception of human rights grounded in a conception of equal positive freedom, in which these rights are seen to apply beyond the coercive political institutions to which Pogge primarily confines them (e.g. to prohibiting domestic violence), and in which they can guide the development of economic, social and political forms to enable their fulfillment.

The stability of each of the theories of separably closed fields is proved, in the manner of Shelah's proof of the corresponding result for differentially closed fields. These are at present the only known stable but not superstable theories of fields. We indicate in § 3 how each of the theories of separably closed fields can be associated with a model complete theory in the language of differential algebra. We assume familiarity with some basic facts about model completeness [4], stability (...) [7], separably closed fields [2] or [3], and (for § 3 only) differential fields [8]. (shrink)

IntroductionEnabling education programs, otherwise known as Foundation Studies or Preparatory programs, provide pathways for students typically under-represented in higher education. Students in Enabling programs often face distinct challenges in their induction to academic culture which can implicate them in cases of misconduct. This case study addresses a gap in the enabling literature reporting on how a culture of academic integrity can be developed for students and staff in these programs through an educative approach.Case descriptionThis paper outlines how an educative approach (...) to academic integrity is implemented within the Enabling programs of two Australian universities.Discussion and reflectionThis case study reflects upon an approach which makes specific reference to the key elements of ‘support’, ‘approach’ and ‘responsibility’ as highlighted in Bretag and Mahmud’s seminal paper. The paper reports a reduction in misconduct cases at the two institutions suggesting a positive correlation between the interventions and students’ understanding of ethical academic practice. This study reflects upon practitioner experiences with academic integrity investigations to evaluate the effectiveness of this approach.ConclusionsThe authors show that it is possible to ensure academic integrity practices and values are upheld within a supportive learning environment appropriate to a students’ level of study.

Since the mid-twentieth century, the concept of the Turing machine has dominated thought about effective procedures. This paper presents an alternative to Turing's analysis; it unifies, refines, and extends my earlier work on this topic. I show that Turing machines cannot live up to their billing as paragons of effective procedure; at best, they may be said to provide us with mere procedure schemas. I argue that the concept of an effective procedure crucially depends upon distinguishing procedures as definite courses (...) of action(- types) from the particular courses of action(-tokens) that actually instantiate them and the causal processes and/or interpretations that ultimately make them effective. On my analysis, effectiveness is not just a matter of logical form; `content' matters. The analysis I provide has the advantage of applying to ordinary, everyday procedures such as recipes and methods, as well as the more refined procedures of mathematics and computer science. It also has the virtue of making better sense of the physical possibilities for hypercomputation than the received view and its extensions, e.g. Turing's o-machines, accelerating machines. (shrink)

This study uses panel data to investigate the different roles of the Chinese government in influencing companies’ decision making about corporate environmental reporting (CER) via a two-stage process. The results show that the Chinese government appears to mainly influence the decision whether to disclose or not, but has limited influence on how much firms disclose. The results also show that the traditional model of authoritarian capitalism (under which state-owned enterprises [SOEs] are the major governance arrangement) is transforming into a new (...) model. In the new model of authoritarian capitalism, the Chinese government uses newer, more sophisticated tools to manage both state-owned and non–state-owned companies. In addition, these new governance arrangements appear to be more efficient than the traditional model. The findings of this study have implications for both the Chinese government and for Chinese companies, as well as making important contributions to the literature and knowledge of CER in China.

The assumption that all life on Earth today shares the same basic molecular architecture and biochemistry is part of the paradigm of modern biology. This paper argues that there is little theoretical or empirical support for this widely held assumption. Scientists know that life could have been at least modestly different at the molecular level and it is clear that alternative molecular building blocks for life were available on the early Earth. If the emergence of life is, like other natural (...) phenomena, highly probable given the right chemical and physical conditions then it seems likely that the early Earth hosted multiple origins of life, some of which produced chemical variations on life as we know it. While these points are often conceded, it is nevertheless maintained that any primitive alternatives to familiar life would have been eliminated long ago, either amalgamated into a single form of life through lateral gene transfer (LGT) or alternatively out-competed by our putatively more evolutionarily robust form of life. Besides, the argument continues, if such life forms still existed, we surely would have encountered telling signs of them by now. These arguments do not hold up well under close scrutiny. They reflect a host of assumptions that are grounded in our experience with large multicellular organisms and, most importantly, do not apply to microbial forms of life, which cannot be easily studied without the aid of sophisticated technologies. Significantly, the most powerful molecular biology techniques available—polymerase chain reaction (PCR) amplification of rRNA genes augmented by metagenomic analysis—could not detect such microbes if they existed. Given the profound philosophical and scientific importance that such a discovery would represent, a dedicated search for ‘shadow microbes’ (heretofore unrecognized ‘alien’ forms of terran microbial life) seems in order. The best place to start such a search is with puzzling (anomalous) phenomena, such as desert varnish, that resist classification as ‘biological’ or ‘nonbiological’. Ó 2007 Elsevier Ltd.. (shrink)

The pluralism of methodologies and severe time constraints pose important challenges to pedagogy in clinical ethics. We designed a step-by-step student handbook to operate within such constraints and to respect the methodological pluralism of bioethics and clinical ethics. The handbook comprises six steps: Step 1: What are the facts of the case?; Step 2: What are your obligations to your patient?; Step 3: What are your obligations to third parties to your relationship with the patient?; Step 4: Do your obligations (...) converge or conflict?; Step 5: What is the strongest objection that could be made to the identification of convergence in step 4 or the arguments in step 4? How can this objection be effectively countered?; and Step 6: How could the ethical conflict, or perceived ethical conflict, have been prevented? (shrink)

Why are some things spoken and other things sung? What effect does singing have on the hearer or the singer and especially on their affective and intellectual cognition? This essay, which was originally conceived and delivered as a lecture, asks why it was that Saint Augustine was so ambivalent about singing. It examines both his reasons and his tactics for avoiding singing as well as the ways and the contexts in which he can be shown to have positively embraced it. (...) It argues that both Augustine’s theological reflection and his practice included a role for spontaneous, non-verbal expression in singing, as well as for the more measured poetry of the psalms and hymns that, in Augustine’s day, had already become a part of the liturgy and of corporate worship.

This paper explores the conduct of performance appraisals of nurses in a New Zealand hospital, and how fairness is perceived in such appraisals. In the health sector, performance appraisals of medical staff play a key role in implementing clinical governance, which, in turn, is critical to containing health care costs and ensuring quality patient care. Effective appraisals depend on employees perceiving their own appraisals to be fair both in terms of procedure and interaction with their respective appraiser. We examine qualitative (...) data from interviews and focus groups, involving 22 nurses in a single department, to determine whether perceived injustices impact on the effective implementation of the appraisal system. Our results suggest that particular issues had been causing some sense of injustice, and most of these were procedural. Potential solutions focus on greater formalisation of the performance appraisal process, and more training for appraisers and appraisees. (shrink)

Is one of the roles of theory in biology answering the question “What is life?” This is true of theory in many other fields of science. So why should not it be the case for biology? Yet efforts to identify unifying concepts and principles of life have been disappointing, leading some (pluralists) to conclude that life is not a natural kind. In this essay I argue that such judgments are premature. Life as we know it on Earth today represents a (...) single example and moreover there is positive evidence that it may be unrepresentative of life considered generally. Furthermore, as I discuss, the prototype for theorizing about life has traditionally been based on multicellular plants and animals. Yet biologists have discovered that the latter represent a rare, exotic, and fairly recent form of Earth life. By far the oldest, toughest, most extensive, and diverse form of life on our planet is unicellular, prokaryotic microbes, and there are reasons to suppose that this is almost certainly true elsewhere in the universe as well. If there are explanatorily and predictively powerful, biologically distinctive principles for life that can be gleaned from our insular example of life it is more likely that they will be found among the microbes. I discuss some provocative ways in which unicellular microbes differ from multicellular eukaryotes and argue that some of them just might provide us with key insights into the nature of life.

: Advances in medical technology now permit children who need ventilator assistance to live at home rather than in hospitals or institutions. What does this ventilator-dependent life mean to children and their families? The impetus for this essay comes from a study of the moral experience of 12 Canadian families—parents, ventilator-dependent child, and well siblings. These families express great love for their children, take on enormous responsibilities for care, live with uncertainty, and attempt to create "normal" home environments. Nevertheless, they (...) experience social isolation, sometimes even from their extended families and health care providers. Their lives are constrained in many ways. The challenges faced by parents of technology-dependent children raise questions of justice within society and within families. (shrink)

WINDSOR C, DOUGLAS C and HARVEY T. Nursing Inquiry 2012; 19: 213–222 Nursing and competencies — a natural fit: the politics of skill/competency formation in nursingThe last two decades have seen a significant restructuring of work across Australia and other industrialised economies, a critical part of which has been the appearance of competency based education and assessment. The competency movement is about creating a more flexible and mobile labour force to increase productivity and it does so by redefining work as (...) a set of transferable or ‘soft’ generic skills that is transportable and is the possession of the individual. This article sought to develop an analysis of competency based clinical assessment of nursing students across a bachelor of nursing degree course. This involved an examination of a total of 406 clinical assessment tools that covered the years 1992–2009 and the three years of a bachelor degree. Data analysis generated three analytical findings: the existence of a hierarchy of competencies that prioritises soft skills over intellectual and technical skills; the appearance of skills as personal qualities or individual attributes; and the absence of context in assessment. The article argues that the convergence in nursing of soft skills and the professionalisation project reform has seen the former give legitimacy to the enduring invisibility and devaluation of nursing work.

El artículo muestra que, en numerosos contextos, Agustín reflexiona sistemáticamente sobre la teología de la escucha transformadora, y da en la práctica un destacado ejemplo de ella. Se centra en los tres últimos libros de las Confesiones, particularmente el libro 11, donde Agustín presenta una versión única, pero también paradigmática, del arte y práctica de oír.

The public communication of science and technology has become increasingly important over the last several decades. However, understanding the audience that receives this information remains the weak link in the science communication process. This essay provides a brief review of some of the issues involved, discusses results from an audience-based study, and suggests some strategies that both scientists and journalists can use to modify media coverage in ways that can help audiences better understand major public issues that involve science and (...) technology.

In this paper I consider the possibility that failing to fulfill the Kantian obligation to protect one’s rational nature might actually vitiate future instances of this obligation. I respond to this dilemma by defending a novel interpretation of Kant’s views on the relation between the value we have and the respect we are owed. I argue, contra the received view among Kant scholars, that the feature in virtue of which someone has unconditional and incomparable value is not the same feature (...) in virtue of which she is owed the respect that constrains how she may be treated. So, even though someone who fails to attempt to protect her rational nature fails to respect herself in the right way, and even though this moral failing does make her lose a certain kind of value, her obligations to respect herself do not go away.
