In December and January of 1983–1984, archaeologists excavating the tomb of an ancient Chinese provincial bureaucrat at a Western Han Dynasty site near Zhangjiashan, in Jiangling county, Hubei Province, discovered a number of books on bamboo strips, including inter alia works on legal statutes, military practice, and medicine. Among these was a previously unknown mathematical work on some 200 bamboo strips, the Suan shu shu, or Book of Numbers and Computations. Based upon other works found in the tomb, especially a (...) copy of the Er nian lü ling (Laws and Decrees of the Second Year (of the reign of empress Lü, i.e. Lü Hou)), archaeologists have dated the tomb to ca. 186 BCE (Lü Hou’s regency lasted from 188 to 180 BCE). The Suan shu shu, as the earliest yet discovered work devoted specifically to mathematics from ancient China, has stirred considerable interest among Chinese historians of science. The translation and commentary offered here draw extensively on the works cited in Sect. 3 below. Several appendixes devoted to specific issues related to translating the Suan shu shu, including its title and the problem of determining English equivalents for various commodities that arise in the text, may be found in Appendix II.

BackgroundAlthough the peer review process is believed to ensure scientific rigor, enhance research quality, and improve manuscript clarity, many investigators are concerned that the process is too slow, too expensive, too unreliable, and too static. In this feasibility study, we sought to survey corresponding authors of recently published clinical research studies on the speed and efficiency of the publication process.MethodsWeb-based survey of corresponding authors of a 20% random sample of clinical research studies in MEDLINE-indexed journals with Ovid MEDLINE entry dates (...) between December 1 and 15, 2016. Survey addressed perceived manuscript importance before first submission, approximate first submission and final acceptance dates, and total number of journal submissions, external peer reviews, external peer reviewers, and revisions requested, as well as whether authors would have considered publicly sharing their manuscript on an online platform instead of submitting to a peer-reviewed journal.ResultsOf 1780 surveys distributed, 27 corresponding authors opted out or requested that we stop emailing them and 149 emails failed (e.g., emails that bounced n = 64, returned with an away from office message n = 70, or were changed/incorrect n = 15), leaving 1604 respondents, of which 337 completed the survey (21.0%). Respondents and non-respondents were similar with respect to study type and publication journals’ impact factor, although non-respondent authors had more publications (p = 0.03). Among respondents, the median impact factor of the publications’ journal was 2.7 (interquartile range (IQR), 2.0–3.6) and corresponding authors’ median h-index and number of publications was 9 (IQR, 3–20) and 27 (IQR, 10–77), respectively. The median time from first submission to journal acceptance and publication was 5 months (IQR, 3–8) and 7 months (IQR, 5–12), respectively. Most respondents (62.0%, n = 209) rated the importance of their research as a 4 or 5 (5-point scale) prior to submission. Median number of journal submissions was 1 (IQR, 1–2), external peer reviews was 1 (IQR, 1–2), external peer reviewers was 3 (IQR, 2–4), and revisions requested was 1 (IQR, 1–1). Sharing manuscripts to a public online platform, instead of submitting to a peer-reviewed journal, would have been considered by 55.2% (n = 186) of respondents.ConclusionCorresponding authors have high perceptions of their research and reported requiring few manuscript submissions prior to journal acceptance, most commonly by lower impact factor journals.

In lieu of an abstract, here is a brief excerpt of the content:Murder in the Garden? The Envy of the Gods in Genesis 2 and 3 Paul DuffJoseph Hallman George Washington University University of St. Thomas According to Walter Brueggemann, "No text in Genesis (or likely in the entire Bible) has been more used, interpreted and misunderstood" than the story of Adam and Eve in the garden. "This applies to careless, popular theology as well as to the doctrine of the (...) church"(41). Augustine attempted to explain the first few chapters of Genesis on no fewer than five different occasions throughout his career. Based on his reading ofPaul, Augustine and Western Christianity after him believed that the entire human race inherited the disobedience ofAdam and Eve. The story in Genesis 2-3 represents the beginning ofthe J narrative, the so-called Yahwist account of the creation which originated in the early years ofthe Israelite monarchy.8 Commentators have long acknowledged a variety ofelements in the Yahwist creation account which complicate its interpretation and defy any satisfactory explanation. Among the more puzzling elements in the story are, first, the implication in Gen. 3:22 of a plurality of divine beings, a fact which seems to contradict the rest ofthe narrative and which also flies in the face of Israelite monotheism. Second, according to Gen. 2:17, God threatens Adam with the punishment of 8 The Yahwist document, originally independent, was later combined with three other strands of ancient material to form the Pentateuch. For a recent study ofthe "Documentary Hypothesis," see Richard Friedman. 1 84Paul DuffandJoseph Hallman immediate death for transgressing the deity's prohibition (cf. 3:3, 3:4). God does not carry out the threatened punishment, however, nor does the text offer the reader an explanation for the deity's commutation ofthe sentence (Westermann 224-5). Third, the origin and nature ofthe serpent in the story is unclear. Where did he come from? The identification ofthis figure with Satan in the later tradition has no support in the text (Westermann 237-9). Finally, the prohibition not to eat ofthe single tree in the garden appears to be arbitrary. Hence the crime of Adam and Eve is obviously contrived. Despite the fact that the original sentence of death for their disobedience was not carried out, the curses invoked on Adam and Eve seem hardly warranted by the offense. Consequently, some sections ofthe text depict the deity as a petty tyrant, certainly a very different picture than that given by other scriptures ofthe Jewish and Christian traditions. We believe these difficulties can be overcome by approaching Genesis 2-3 from a Girardian perspective.9 We propose that this story has evolved10 in order to hide its original meaning. As a result—following Girard's understanding of the function and evolution of mythology—we will endeavor to "deconstruct" Genesis 2-3 in order to trace the evolution ofthis myth from its origin in a primal crime. This will enable us to explain the inconsistencies in the text as it stands and to appreciate the final revisions made by the biblical author(s). We will begin with a brief discussion of Girard's understanding ofmyth. Then we will turn to the problems ofthe Genesis text. Girard on myth According to Girard, myth is, quite simply, a narrative about a primal murder, rewritten from the vantage point ofthe killers (1977a, 64-7, 91-5; 1986, 24-44). As such, mythology covers up the role of the victimage mechanism as the basis ofculture. Myths which disguise or cover up such a crime can take many forms. For instance, the foundational murder of an 9 In his recent book on Paul, Robert Hamerton-Kelly presents a Girardian interpretation of this passage which is completely different from ours (92-7). Since Hamerton-Kelly appears to read the myth at face value without a sense of development, he, like most interpreters, ends with somewhat tortuous conclusions. 10It is virtually certain that the account found in Gen. 2 and 3 did not come into being as a free composition of the Yahwist. But, as Claus Westermann has pointed out in his history ofthe exegesis ofthis passage (186-91), despite the fact that most see it as a product of a long... (shrink)

We suggest that policies will be less popular when individuals personally have to pay for them rather than when others have to pay (i.e., a Not Out of My Bank Account or NOMBA effect). Dual process models of persuasion suggest that personally having to pay would motivate scrutiny of persuasive messages making it essential to use effective science communication tactics when using climate science to support climate change policies. A pilot experiment (N = 186) and main study (N = 758) (...) support a NOMBA effect with less policy support (Pilot study) and lower recommended fees (Main study) for a policy that would require participants, rather than another group, to pay a fee for community solar panels. Consistent with dual process models and suggesting systematic processing, only when participants would have to pay the fee, messages using strong (vs. weak) science communication tactics increased support for policies (Pilot study), increased the favorability of thoughts about the policy (Main study) and these thoughts subsequently predicted policy support (Main study). Inconsistent with propositions that information about expert sources would be a heuristic or bolster science messages, expert consensus information did not influence thoughts or policy support in any study condition. Efforts to understand climate change policy support would benefit from attending to research on dual process models of persuasion, including understanding how different types and degree of outcome relevance can alter how people process science information used to bolster support for climate change policies.

Theories of discourse bring to realism new ideas about how knowledge develops and how representations of reality are influenced. We gain an understanding of the conceptual aspect of social life and the processes by which meaning is produced. This collection reflects the growing interest realist critics have shown towards forms of discourse theory and deconstruction. The diverse range of contributions address such issues as the work of Derrida and deconstruction, discourse theory, Eurocentrism and poststructuralism. What unites all of the contributions (...) is a sense that it is essential to provide a realist alternative to the hitherto dominance of social constructionism, hermeneutics and postmodernism, over many of the issues discussed. By developing a realist perspective the different authors attempt to embed discourse within the structured nature of the reality of the world. Realism can situate language, discourse and ideology within context specific, or 'causally efficacious' circumstances. Realism can help to uncover issues of power, representation, and subjectivity and how discursive and other social practices produce real effects. This can help us understand the manner in which social structures are reproduced through various forms of ideology and discourse. And by knowing this, we can start to address questions concerning human emancipation and how the world is to be transformed. (shrink)

Abstract The use of photo research methods is influenced by underlying ontological and epistemological assumptions. Variant assumptions about reality and knowledge converge to conceive a relationship between the knower and what can be known. These assumptions provide the rationale for decided ways of engaging participants in the process of scientific inquiry. In this paper, we examine how perspectives of realism and relativism may shape epistemological understandings and influence type and use of photo methods in qualitative research. Based on deliberations about (...) underlying ontological and epistemological assumptions and related strengths and challenges of photo methods, we assert that photo methods contribute to the development of knowledge that both matters to participants and informs nursing practice.

Topics covered in Discrete Mathematics have become essential tools in many areas of studies in recent years. This is primarily due to the revolution in technology, communications, and cyber security. The book treats major themes in a typical introductory modern Discrete Mathematics course: Propositional and predicate logic, proof techniques, set theory (including Boolean algebra, functions and relations), introduction to number theory, combinatorics and graph theory. An accessible, precise, and comprehensive approach is adopted in the treatment of each topic. The ability (...) of abstract thinking and the art of writing valid arguments are emphasized through detailed proof of (almost) every result. Developing the ability to think abstractly and roguishly is key in any areas of science, information technology and engineering. Every result presented in the book is followed by examples and applications to consolidate its comprehension. The hope is that the reader ends up developing both the abstract reasoning as well as acquiring practical skills. All efforts are made to write the book at a level accessible to first-year students and to present each topic in a way that facilitates self-directed learning. Each chapter starts with basic concepts of the subject at hand and progresses gradually to cover more ground on the subject. Chapters are divided into sections and subsections to facilitate readings. Each section ends with its own carefully chosen set of practice exercises to reenforce comprehension and to challenge and stimulate readers. As an introduction to Discrete Mathematics, the book is written with the smallest set of prerequisites possible. Familiarity with basic mathematical concepts (usually acquired in high school) is sufficient for most chapters. However, some mathematical maturity comes in handy to grasp some harder concepts presented in the book. (shrink)

I will argue the free market in babies or in women's bodies created by an institution of paid surrogate motherhood is contrary to Kantian principles of personhood and to the feminist principle that men do not have-and cannot gain through contract, marriage, or payment of money-a right to the sexual or reproductive use of women's bodies.

There is an interpretation of Parmenides’poem which has not yet had, but deserves, a hearing. It reconciles two of the most prominent views of the meaning of the verb ‘to be’ as it occurs in the poem. It agrees with the spirit of those who interpret ‘εἷναι’ as‘existence.’ It agrees with the letter of those who interpret ‘εἷν αι’ as the copula.

Belief storage is often modeled as having the structure of a single, unified web. This model of belief storage is attractive and widely assumed because it appears to provide an explanation of the flexibility of cognition and the complicated dynamics of belief revision. However, when one scrutinizes human cognition, one finds strong evidence against a unified web of belief and for a fragmented model of belief storage. Using the best available evidence from cognitive science, we develop this fragmented model into (...) a nascent theory of the cognitive architecture of belief storage. (shrink)

The first part of the paper argues that there is no analysis of (or statement of sufficient conditions for) "justification." The problem is that as an analysis it would have to be lawlike. But if it were lawlike it could be used to support a counterfactual conditional to the effect that if I were justified in believing it I would satisfy its analysans. I argue that since no analysis can be so used there is no such analysis. In part II (...) I show how the conclusion of part I supports naturalism and clarify one version of naturalism. (shrink)

One of the greatest revolutions in mathematics occurred when Georg Cantor (1845-1918) promulgated his theory of transfinite sets.

As an alternative to rights theory, John Ladd proposes an ethics of responsibility based on interpersonal relationships. These relationships, described as friendships, are personal in nature, founded on trust, and obtain between doctor and patient, parent and child, etc. Ladd presents his views in a most appealing way – helping the needy, being friends with the doctor. We argue that Ladd's ethics of responsibility is plausible only because he ignores the facts of power which rights theory was designed to take (...) into account, and that rights and the corresponding institutional model of medicine are indeed appropriate to the physician/patient relationship.
