This article explores the carnal dimensions of existence through ethnographic research in a mixed martial arts club. Mixed martial arts (MMA) is an emergent sport where competitors in a ring or cage utilize strikes (punches, kicks, elbows and knees) as well as submission techniques to defeat opponents. Through data gathered from in-depth interviews with MMA practitioners and participant observation in an MMA club, I elucidate the social processes that are integral to the production of an MMA fighter habitus. I examine (...) how body techniques are learned and become attached to the identity of mixed martial arts fighters. Using Crossley’s concept of reflexive body techniques, I examine how MMA fighters engage in body callusing through use of reflexive body techniques thereby allowing them to withstand the rigors of the sport.

This volume provides an integrated and wide-ranging set of primary-source readings on the relationship between moral values and economic activity, as articulated by some of the leading figures in Western civilization.

Mood disorders, including major depressive disorder and bipolar disorder, are highly prevalent, frequently disabling, and sometimes deadly. Additional research and more effective medications are desperately needed, but clinical trials research in mood disorders is fraught with ethical issues. Although many authors have discussed these issues, most do so from a theoretical viewpoint. This manuscript uses available empirical data to inform a discussion of the primary ethical issues raised in mood disorders research. These include issues of consent and decision-making capacity, including (...) patients’ motivations for participating in research. We also address drug withdrawals, placebo controls, and the overall safety of research. Finally, we examine the extant literature for studies discussing potential indirect benefits of clinical trials research to participants. Taken together, the evidence suggests that clinical trials research incorporating drug withdrawals and placebo controls can be conducted safely and ethically, even in patients with severe or treatment-resistant mood disorders. In fact, given the dearth of effective treatment options for this population, it is our opinion that a moral imperative exists to extend the offer of research participation to severely ill or treatment-resistant groups.

People coordinate body postures and gaze patterns during conversation. We review literature showing that (1) action embodies cognition, (2) postural coordination emerges spontaneously when two people converse, (3) gaze patterns influence postural coordination, (4) gaze coordination is a function of common ground knowledge and visual information that conversants believe they share, and (5) gaze coordination is causally related to mutual understanding. We then consider how coordination, generally, can be understood as temporarily coupled neuromuscular components that function as a collective unit (...) known as a coordinative structure in the motor control literature. We speculate that the coordination of gaze and body sway found in conversation may be understood as a cross‐person coordinative structure that embodies the goals of the joint action system. (shrink)

Media multitasking entails simultaneously engaging in multiple tasks when at least one of the tasks involves media. Across two studies, we investigated one potential trigger of media multitasking, state boredom, and its relation to media multitasking. To this end, we manipulated participants’ levels of state boredom using video mood inductions prior to administering an attention-demanding 2-back task during which participants could media multitask by playing a task-irrelevant video. We also examined whether trait boredom proneness was associated media multitasking. We found (...) no direct evidence that state boredom leads to media multitasking. However, trait boredom proneness correlated with greater amounts of media multitasking in Experiment 1, but not in Experiment 2. Surprisingly, in both experiments, post-task ratings of state boredom were equivalent across conditions, alerting us to the short-lived effects of video mood inductions and the boring nature of cognitive tasks.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Explorations in Ancient and Modern Philosophy by Myles F. BurnyeatAllison Piñeros Glasscock and Elizabeth C. Shaw and Staff*BURNYEAT, Myles F. Explorations in Ancient and Modern Philosophy, vol. 4. Cambridge: Cambridge University Press, 2022. xii + 395 pp. Cloth, $120.00The eleven essays in this collection were originally published while Burnyeat was at All Souls College, Oxford (1996–2006) and during his subsequent retirement. Like volume 3 of the same series, (...) the collection was published posthumously, with editorial work undertaken by Carol Atack, Malcolm Schofield, and David Sedley. Part I contains seven essays on topics in ontology and epistemology; part II contains four essays on physics and optics. The figures examined include the usual suspects—Plato and Aristotle (plus an appearance by Aquinas)—but Burnyeat also draws our attention to some less appreciated accomplices to the ancient philosophical project: the Platonist commentator Numenius of Apamea, the Pythagorean Archytas of Tarentum, and Anaxarchus of Abdera, a follower of Democritus. The result is a collection that showcases one of Burnyeat's greatest strengths: his ability to identify the clues left for us in ancient texts and to produce from them compelling and exquisitely detailed accounts of what ancient philosophers were thinking and why.One of the final papers of the volume illustrates Burnyeat's detective acumen. "Archytas and optics" starts from the following question: Why is optics absent from the mathematical curriculum Plato sketches in the Republic? Burnyeat hypothesizes that if mathematical optics existed when the Republic was written, Plato likely excised it from the curriculum on the grounds that the discipline would lead the student to focus on visible things and their appearances. The bulk of the paper is devoted to establishing the antecedent of this conditional. Burnyeat argues that mathematical optics did exist at the time of the Republic's writing, and he posits the noncanonical Pythagorean Archytas as its founder. To recognize the significance of this lacuna in the Republic's curriculum and to provide a persuasive identification of the founder of an entire discipline is already to make a substantial contribution to scholarship. But how Burnyeat arrives at his central conclusion is equally impressive. He takes the reader on a tour of Aristotle, Plato, and Iamblichus, fragment 4 of Archytas, and the Apologia of Apuleius (whom readers might better recognize as the novelist responsible for The Golden [End Page 345] Ass). The result is not only an answer to the paper's central question, but a deeper understanding of the broader intellectual network in which canonical figures like Plato and Aristotle operated.No fragment is too small to catch Burnyeat's notice, nor is any line in a manuscript too faint. Part I of the collection includes Burnyeat's famous paper "Kinēsis vs. energeia: a much-read passage in (but not of) Aristotle's Metaphysics." The central argument is that Metaphysics 9.6.1048b18–35 is out of place. It was written by Aristotle for a different context and should not be printed in book 9. Because this article is so well known, I will not dwell on the details of the argument, but once again Burnyeat's methodology is worthy of comment. The first part of the paper offers a careful examination of the Metaphysics's manuscript tradition that attends both to what is present and to what is absent. For example, we learn that the focus passage is missing from an entire branch of the tradition, which Burnyeat suggests is the result of a learned excision. Later, Burnyeat develops a psychological sketch of the scribe of manuscript Ab beginning from the observation that a faint line is drawn through part of the focus passage. He argues that the scribe's motivation is not disapproval of the passage's contents but a desire to keep his text and commentary in sync. Observations like these provide the foundation for Burnyeat's thesis about the philosophical import of the focus passage, and they demonstrate that the physical record can be just as vital to reconstructions of ancient philosophy as the words that the record preserves.Occasionally, Burnyeat offers more direct admonitions to his readers about how to approach ancient philosophy.

BackgroundIn December 2014, China announced that only voluntarily donated organs from citizens would be used for transplantation after January 1, 2015. Many medical professionals worldwide believe that China has stopped using organs from death-row prisoners.DiscussionIn the present article, we briefly review the historical development of organ procurement from death-row prisoners in China and comprehensively analyze the social-political background and the legal basis of the announcement. The announcement was not accompanied by any change in organ sourcing legislations or regulations. As a (...) fact, the use of prisoner organs remains legal in China. Even after January 2015, key Chinese transplant officials have repeatedly stated that death-row prisoners have the same right as regular citizens to “voluntarily donate” organs. This perpetuates an unethical organ procurement system in ongoing violation of international standards.ConclusionsOrgan sourcing from death-row prisoners has not stopped in China. The 2014 announcement refers to the intention to stop the use of organs illegally harvested without the consent of the prisoners. Prisoner organs procured with “consent” are now simply labelled as “voluntarily donations from citizens”. The semantic switch may whitewash sourcing from both death-row prisoners and prisoners of conscience. China can gain credibility only by enacting new legislation prohibiting use of prisoner organs and by making its organ sourcing system open to international inspections. Until international ethical standards are transparently met, sanctions should remain. (shrink)

The 65th year of a scholar who has devoted 40 years to editing and elucidating Robert Grosseteste provides us with a collection of essays. Not surprisingly, they emanate from colleagues and former students of Richard Dales and reflect his interest, among other concerns, in Grosseteste's aspectus et affectus - range of vision and disposition of mind - those twin peaks with which the 13th century thinker helped to get Christian thought through Aristotle without mutual destruction.

We investigated the coupling between a speaker's and a listener's eye movements. Some participants talked extemporaneously about a television show whose cast members they were viewing on a screen in front of them. Later, other participants listened to these monologues while viewing the same screen. Eye movements were recorded for all speakers and listeners. According to cross-recurrence analysis, a listener's eye movements most closely matched a speaker's eye movements at a delay of 2 sec. Indeed, the more closely a listener's (...) eye movements were coupled with a speaker's, the better the listener did on a comprehension test. In a second experiment, low-level visual cues were used to manipulate the listeners' eye movements, and these, in turn, influenced their latencies to comprehension questions. Just as eye movements reflect the mental state of an individual, the coupling between a speaker's and a listener's eye movements reflects the success of their communication. (shrink)

It is an observed fact that human populations differ in genetic composition. Some of the inherited diversity is due to combined effects of many genes. Although it would be interesting to know the magnitude and nature of the genetic contribution to some characters under polygenic control, such as intelligence or physique, environmental effects may be so great that no genetic analysis is possible—as Thoday has pointed out earlier in this symposium. With other polygenic characters, such as skin colour, the genetic (...) component is more obvious but still difficult to analyse precisely. The number of genes involved, their frequency and dominance have not been established. This is one of the reasons why selective effects on such characters are not readily measured, although they probably exist. (shrink)

Two types of interleukin 1 (IL‐1α and IL‐1β) have been defined by purifying the molecules from activated human peripheral blood cells, followed by cloning and expressing the molecules in Escherichia coli. Both types of IL‐1 stimulate proliferation and differentiation of T‐ and B‐lymphocytes and induce cartilage proteoglycan degradation but differ in other properties. For example, demineralization and appears to be a major mediator in the pathogenesis of joint erosion in rheumatoid arthritis. Synthetic adjuvants elicit the production of IL‐1 separate from (...) endogenous pyrogen, and this property is required for the new generation of vaccines based on antigens produced by recombinant DNA technology.

Bone morphogenetic proteins (BMPs) are typically members of the transforming growth factor β (TGF-β) family with diverse roles in embryonic development. At least five genes with homology to BMPs are expressed during Xenopus development, along with their receptors and intracellular signalling pathways. The evidence suggests that BMPs have roles to play in both mesoderm induction and dorsoventral patterning. Studies in Xenopus have also identified a number of inhibitory binding proteins for the classical BMPs, encoded by genes such as chordin and (...) noggin. These proteins appear to be responsible for establishing a morphogen gradient of BMP4 activity, which specifies different dorsoventral fates in early gastrulae. An emerging theme is that inhibition of BMP signalling is an important mechanism regulating cell fate decisions in early development. BioEssays 21:751–760, 1999. © 1999 John Wiley & Sons, Inc.

Elimination of state laws that preempt local antismoking ordinances is a national health objective. However, the tobacco industry and its supporters have continued to pursue statelevel preemption of local tobacco control ordinances as part of an apparent strategy to avoid the difusion of grassroots antismoking initiatives. And, an increasing number of challenges to local ordinances by the tobacco industry and persons supported by the tobacco industry are being decided in state supreme courts and courts of appeals. The outcomes of seemingly (...) similar cases about the validity of local smoke-free air ordinances vary signifcantly by state. This paper examines the common and unique aspects of the decisions and the potential implications of court rulings on preemption for future state tobacco control eforts and achievement of national health objectives around the elimination of preemption. Using a search strategy developed for the Centers for Disease Control and Prevention's State Tobacco Activities Tracking and Evaluation System, cases where a state or federal appellate level court made a fnding on the validity of a local smoke-free air ordinance or regulation were identifed in 19 states. In contrast to previous studies, we found that cases in approximately half of states were decided for local governments. We also found that across the states, courts were considering similar factors in their decisions including the extent to which: the local government possessed the authority to pass the ordinance, the ordinance conficted with the state constitution, and state statutes preempt the ordinance.

Despite governmental and private antismoking initiatives, tobacco smoking remains a significant public health and economic challenge. The Centers for Disease Control and Prevention estimates that for each year between 1997 and 2001, cigarette smoking and exposure to secondhand smoke caused approximately 438,000 U.S. residents to die prematurely, resulting in 5.5 million years of potential life lost, and in $92 billion dollars of lost productivity. Also, despite convincing scientific data that laws against indoor smoking protect people from the negative health effects (...) of cigarette smoke, not all states have afforded their residents this protection. As of July 2007, 16 states neither restricted nor banned indoor smoking in restaurants, private worksites, or government worksites, and many state statutes only required separate rooms for smokers rather than eliminating all smoking inside buildings. In several states, local governments have attempted to fill this gap by adopting their own antismoking measures. (shrink)

It is hypothesized that iron from biological tissues, liberated during decay, may have played a role in inhibiting loss of anatomical information during fossilization of extinct organisms. Most tissues in the animal kingdom contain iron in different forms. A widely distributed iron‐bearing molecule is ferritin, a globular protein that contains iron crystallites in the form of ferrihydrite minerals. Iron concentrations in ferritin are high and ferrihydrites are extremely reactive. When ancient animals are decaying on the sea floor under anoxic environmental (...) conditions, ferrihydrites may initialize the selective replication of some tissues in pyrite FeS2. This model explains why some labile tissues are preserved, while other more resistant structures decay and are absent in many fossils. A major implication of this hypothesis is that structures described as brains in Cambrian arthropods are not fossilization artifacts, but are instead a source of information on anatomical evolution at the dawn of complex animal life.

Corballis's explanation for right-handedness in humans relies heavily on the gestural protolanguage hypothesis, which he argues for by a series of “intuition pumps.” Scrutinizing the mirror system hypothesis and modern gesture as components of the argument, we find that they do not provide the desired evidence of a gestural precursor to speech.
