An organic petrology evaluation and a determination of solid bitumen reflectance [Formula: see text] were completed for organic-rich Triassic Yanchang Formation mudrocks from the Ordos Basin, north-central China, as part of a larger investigation of “shale gas” resources. These data were integrated with information from Rock-Eval programmed pyrolysis to show that the samples are in the peak oil window of thermal maturity and that organic matter is dominated by solid bitumen with minor amounts of type III kerogen from vascular land (...) plants. Describing a “kerogen type” for these rocks based strictly on parameters determined from programmed pyrolysis is misleading because the original organic matter has converted to hydrocarbons, a large proportion of which may have been expelled into adjacent reservoir facies. However, based on the comparison with immature-early mature lacustrine mudrock and marine shale, we suggest that the original organic matter in the organic-rich samples examined for our study may have been type I/II kerogen with hydrogen index values of [Formula: see text] TOC.

Our main objectives are to learn if pore-evolution models developed from marine mudrocks can be directly applied to lacustrine mudrocks, investigate what controls the different pore types and sizes of Chang 7 organic matter -rich argillaceous mudstones of the Upper Triassic Yanchang Formation, and describe the texture, fabric, mineralogy, and thermal maturity variation in the Chang 7 mudstones. Lacustrine mudstones from nine cored wells along a depositional dip in the southeastern Ordos Basin, China, were investigated. Helium porosimetry, nitrogen adsorption, and (...) field-emission scanning electron microscopy of Ar-ion milled samples were applied. Measured average total porosity of samples from a proximal to distal transect is higher than those from the two adjacent cored wells. This difference in porosity partly caused by differences in the clay mineral content implies that in the fluvial-deltaic-lacustrine depositional environment, reservoir quality can vary significantly in a short distance. Owing to the uneven distribution of the sample set from proximal to distal area, we mainly evaluate variations in the proximal setting. Results from nitrogen-gas adsorption experiments show that there are four distinct patterns of pore-size distribution within the Chang 7 member of the Yanchang Formation with no particular correlation with mineralogical composition and thermal maturity. The pore network within Chang 7 mudstones is dominated by OM-hosted pores, with a lesser abundance of interparticle and intraparticle pores. The size distribution of mineral-hosted pores within these mudstones is found to be closely related to the rock texture and fabric. Mudstones with well-sorted grains and a higher percentage of coarser grains have more abundant mineral pores. The sizes of OM-hosted pores in these compaction-dominated lacustrine mudstones were one to two orders of magnitude smaller than those in the marine mudstones that display abundant early cementation.

Paul C. Taylor provides an accessible guide to a well-travelled but still-mysterious area of the contemporary social landscape. The result is the first philosophical introduction to the field of race theory and to a non-biological and situational notion of race. Provides the first philosophical introduction to the field of race theory. Outlines the main features and implications of race-thinking; asks questions such as: What is race-thinking? Don’t we know better than to talk about race now? Are there any races? (...) What is it like to have a racial identity? Engages with the ideas of such important figures as Linda Alcoff, K. Anthony Appiah, W.E.B. Du Bois, Howard Winant, and Naomi Zack. Explores the enduring significance of race in relation to culture, personal relationships and social justice. (shrink)
Paul C. H. Lim offers an insightful examination of the polemical debates about the doctrine of the Trinity in seventeenth-century England, showing that this philosophical and theological re-configuration significantly impacted the politics of religion in the early modern period.
The World Health Organisation encourages that blood donation becomes voluntary and unremunerated, a system already operated in the UK. Drawing on public documents and videos, this paper argues that blood donation is regarded and presented as altruistic and supererogatory. In advertisements, donation is presented as something undertaken for the benefit of others, a matter attracting considerable gratitude from recipients and the collecting organisation. It is argued that regarding blood donation as an act of supererogation is wrongheaded, and an alternative account (...) of blood donation as moral obligation is presented. Two arguments are offered in support of this position. First, the principle of beneficence, understood in a broad consequentialist framework obliges donation where the benefit to the recipient is large and the cost to the donor relatively small. This argument can be applied, with differing levels of normativity, to various acts of donation. Second, the wrongness of free riding requires individuals to contribute to collective systems from which they benefit. Alone and in combination these arguments present moral reasons for donation, recognised in communication strategies elsewhere. Research is required to evaluate the potential effects on donation of a campaign which presents blood donation as moral obligation, but of wider importance is the recognition that other-regarding considerations in relation to our own as well as others’ health result in a range not only of choices but also of obligations.

Those who know anything about black history and culture probably know that aesthetics has long been a central concern for black thinkers and activists. The Harlem Renaissance, the Negritude movement, the Black Arts Movement, and the discipline of Black British cultural studies all attest to the intimate connection between black politics and questions of style, beauty, expression, and art. And the participants in these and other movements have made art and offered analyses that wrestle with clearly philosophical issues. In _A (...) Philosophy of Black Aesthetics_, I propose to identify and explore the most significant philosophical issues that emerge from the aesthetic dimensions of black life. The book will consist of eight short chapters, each of which will discuss a complex of related themes and phenomena. Every chapter will begin with one or two illustrative real-world examples, and then use the complexities of these opening cases to introduce the relevant issues. Many people in several fields have explored various bits of the terrain that I’ll cover. But none has surveyed the entire terrain in the name of aesthetics, and none has conducted this survey from an explicitly philosophical perspective. Setting up the project in this way means that its main conclusions will come in two forms. One kind of conclusion will emerge from the way I frame the issues. The two most important points here are that the field of aesthetics ought to cover more than the study of western fine art, and that the field of black aesthetics allows and requires the sort of comprehensive and philosophical analysis that I’ll offer. Another set of conclusions will emerge from my treatment of the specific issues in each chapter. In each case the aim will be to defend, albeit briefly, some position on the major issues raised in each chapter. (shrink)
Corporate social responsibility is a tortured concept. We review the current state of the art across a number of academic disciplines, from accounting to management to theology. In a world that is increasingly global and pluralistic, progress in our understanding of CSR must include theorizing around the micro-level processes practicing managers engage in when allocating resources toward social initiatives, as well as refined measurement of the outcomes of those initiatives on stakeholder and shareholder interests. Scholarship must also account for the (...) influence of diverse, and even mal-adaptive, stakeholders as well as more fully incorporate non-Western philosophical and economic perspectives. Based on this review, we pose five questions that scholars from each of these disciplines should address as the CSR field moves forward. We hope our questions provoke deeper thinking and greater rigor and attention to detail in this important area of business research. (shrink)
The concept of responsibility for health is a significant feature of health discourse and public health policy, but application of the concept is poorly understood. This paper offers an analysis of the concept in two ways. Following an examination of the use of the word ‘responsibility’ in the nursing and wider health literature using three examples, the concept of ‘responsibility for health’ as fulfilling a social function is discussed with reference to policy documents from the UK. The philosophical literature on (...) moral responsibility is introduced, and in considering two versions, reactive attitudes and accountability, it is argued that in application both can be regarded, though with different emphasis, as being constituted in three parts: a responsible agent; having obligations ; and being susceptible to being held responsible if he fails to meet them. The three‐stage model is consistent with the examples of the word responsibility in use, but application to the social function model causes a number of problems for healthcare practice, especially for the reactive attitudes account. Apart from considerable problems in stating what exactly the obligations are and how they can be justified; and how blame might justly be apportioned and by whom, the very ideas of obligation and blame are in conflict within healthcare systems and professional nursing practice which have foundations deeply embedded in the notion of the supremacy of personal autonomy. It is concluded that current application of the concept of responsibility for health is conceptually incoherent, and if it is to retain its place in health policy and discourse, urgent remedy is required.

This essay uses the concept of reconstruction to make an argument and an intervention in relation to the practice and study of black aesthetics. The argument will have to do with the parochialism of John Dewey, the institutional inertia of professional philosophy, the aesthetic dimensions of the US politics of reconstruction, the centrality of reconstructionist politics to the black aesthetic tradition, and the staging of a reconstructionist argument in the film, Black Panther (Coogler 2018). The intervention aims to address the (...) fact that arguments like these tend not to register properly because of certain reflexive and customary limits on some common forms of philosophical inquiry. The sort of professional philosophy I was raised to practise and value tends not to be particularly inclusive and open-minded, especially when it comes to subjects that bear directly on the thoughts, lives, and practices of people racialized as black. black aesthetics, by contrast, is an inherently ecumenical enterprise, reaching across disciplinary and demographic boundaries to build communities of practice and exchange. Hence the need for an intervention: to create the space for arguments and the people who work with them to function across disciplinary and demographic contexts. (shrink)

Intentional rounding, a process involving the performance of regular checks on all patients following a standardised protocol, is being introduced widely in the United Kingdom. The process has been promoted by the Prime Minister and publicised by the Chief Nursing Officer at the Department of Health as well as by influential think tanks and individual National Health Service organisations. An evidence base is offered in justification. This article subjects the evidence base to critical scrutiny concluding that it consists of poor (...) quality studies and serial misreporting of findings and a failure to consider wider concerns, including transference of evidence to differing health-care systems, and the conflation of perception and quality of care. Political promotion and wide implementation of intentional rounding despite the flimsy and questionable evidence base raise questions about the use of evidence in ethical nursing practice and the status of nursing as an autonomous profession.

Using tombstoning (jumping from a height into water) as an example, this article claims that public health policies and health promotion tend to assess the moral status of activities following a version of health maximizing rule utilitarianism, but this does not represent common moral experience, not least because it fails to take into account the enjoyment that various health effecting habits brings and the contribution that this makes to a good life, variously defined. It is proposed that the moral status (...) of health threatening activities should instead be defined by a version of act utilitarianism where both maximizing value and method of calculation are decided by individuals. In this account personal responsibility for health is reduced to the obligation to undertake calculations effectively, comprising of two duties; epistemic and reflective. If there is an individual epistemic duty, it is plausible to suggest that health promotion should present information in a way which facilitates it, but despite the prevalent language of autonomous choice, discussion of health promotion messages, for example, related to drinking and smoking demonstrates that this currently does not happen. Health promotion strategies should seek to encourage reflection about the harm our health effecting behaviour causes others. (shrink)
Many religiously minded materialist philosophers have attempted to understand the doctrine of the survival of death from within a physicalist approach. Their goal is not to show the doctrine false, but to explain how it can be true. One such approach has been developed by Peter van Inwagen. After explaining what I call the duplication objection, I present van Inwagen’s proposal and show how a proponent might attempt to solve the problem of duplication. I argue that the very features of (...) the view that aid the proponent in responding to the duplication objection entails the possibility of an impossible state of affairs—that two distinct persons can at the same time be identical with the same bundle of material simples. The religiously minded materialist is caught between the horns of a dilemma. One’s view regarding human persons must be robust enough to account for personal identity over time, and so not fall to the duplication objection. At the same time, the view must not entail the possibility of two persons temporarily having complete coincident existence. (shrink)
Advertising can be regarded as having two separate functions, one of persuading and one of informing consumers. Against some who claim that persuasive advertising using irrational means is moral as long as the product or service it represents is good or useful, this paper argues that by denigrating human reason such advertising is always immoral. On the other hand, advertisements which present information in a straight-forward and truthful way are always moral no matter what they advertise; indeed, only such advertisements (...) are moral.

This research compares the importance of moral values for corporations' managements, as reported by 97 knowledgeable employees in eight corporations. Does an employee consensus emerge within corporations and does it differ between corporations? To answer this question, an analysis of covariance technique was used to compare the importance of moral values between corporations versus within corporations. Results corroborate the hypothesis that closely matched corporations do differ significantly from one another in the importance of prevailing moral values. Evidence also suggests that (...) the importance of prevailing moral values may be inversely related with company size. Implications for future research and for the practice of management are delineated. (shrink)

Astrobiologists are aware that extraterrestrial life might differ from known life, and considerable thought has been given to possible signatures associated with weird forms of life on other planets. So far, however, very little attention has been paid to the possibility that our own planet might also host communities of weird life. If life arises readily in Earth-like conditions, as many astrobiologists contend, then it may well have formed many times on Earth itself, which raises the question whether one or (...) more shadow biospheres have existed in the past or still exist today. In this paper, we discuss possible signatures of weird life and outline some simple strategies for seeking evidence of a shadow biosphere.

The comprehension principle of set theory asserts that a set can be formed from the objects satisfying any given property. The principle leads to immediate contradictions if it is formalized as an axiom scheme within classical first order logic. A resolution of the set paradoxes results if the principle is formalized instead as two rules of deduction in a natural deduction presentation of logic. This presentation of the comprehension principle for sets as semantic rules, instead of as a comprehension axiom (...) scheme, can be viewed as an extension of classical logic, in contrast to the assertion of extra-logical axioms expressing truths about a pre-existing or constructed universe of sets. The paradoxes are disarmed in the extended classical semantics because truth values are only assigned to those sentences that can be grounded in atomic sentences. (shrink)
