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)

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)

This article introduces the preoccupations and themes that define the study and practice of black aesthetics. It presents a provisional sketch of a field that has long been recognized in other humanities disciplines, but that is only now gaining wide notice in academic philosophy. This sketch emphasizes the aspects of the field that invite specifically philosophic scrutiny, while touching lightly on specific artworks, critical literatures and historical developments. Among the topics that receive attention are the following: race, aesthetic politics, creolization, (...) nationalism, modernity, white supremacy and the blues. (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)

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.

An excellent introduction to mathematical logic, this book provides readers with a sound knowledge of the most important approaches to the subject, stressing the use of logical methods in attacking nontrivial problems. It covers the logic of classes, of propositions, of propositional functions, and the general syntax of language, with a brief introduction that also illustrates applications to so-called undecidability and incompleteness theorems. Other topics include the simple proof of the completeness of the theory of combinations, Church's theorem on the (...) recursive unsolvability of the decision problem for the restricted function calculus, and the demonstrable properties of a formal system as a criterion for its acceptability. 1950 ed.

: All known life requires phosphorus (P) in the form of inorganic phosphate (PO43x or Pi) and phosphate-containing organic molecules. Pi serves as the backbone of the nucleic acids that constitute genetic material and as the major repository of chemical energy for metabolism in polyphosphate bonds. Arsenic (As) lies directly below P on the periodic table and so the two elements share many chemical properties, although their chemistries are sufficiently dissimilar that As cannot directly replace P in modern biochemistry. Arsenic (...) is toxic because As and P are similar enough that organisms attempt this substitution. We hypothesize that ancient biochemical systems, analogous to but distinct from those known today, could have utilized arsenate in the equivalent biological role as phosphate. Organisms utilizing such ‘ weird life ’ biochemical pathways may have supported a ‘ shadow biosphere ’ at the time of the origin and early evolution of life on Earth or on other planets. Such organisms may even persist on Earth today, undetected, in unusual niches. (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.

The peculiar dilemma of the self in our era has been noted by a wide range of writers, even as they have emphasized different aspects of that dilemma, such as the self’s alienation, disorientation, inflation, or fragmentation. In The Self: Beyond the Postmodern Crisis, Paul C. Vitz and Susan M. Felch bring together scholars from the disciplines of psychology, philosophy, theology, literature, biology, and physics to address the inadequacies of modern and postmodern selves and, ultimately, to suggest what an (...) alternative, “transmodern” account of the self might look like. The transmodern self, the editors argue, acknowledges meaning and purpose transcending the individual. In other words, it reflects an understanding of the human person that is not only intimately connected with the Judeo-Christian tradition but also rejects the twin delusions of absolute autonomy and cosmic meaninglessness that mark the present age.

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.

A comparison of the literatures on how infants represent generic object classes, gender and race information in faces, and emotional expressions reveals both common and distinctive developments in the three domains. In addition, the review indicates that some very basic questions remain to be answered regarding how infants represent facial displays of emotion, including (a) whether infants form category representations for discrete classes of emotion, (b) when and how such representations come to incorporate affective meaning, (c) the developmental trajectory for (...) representation of emotional expression at different levels of inclusiveness (i.e., from broad to narrow or narrow to broad?), and (d) whether there is superior discrimination ability operating within more frequently experienced emotion categories.

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)

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)
