Philippe Descola has become one of the most important anthropologists working today, and Beyond Nature and Culture has been a major influence in European intellectual life since its French publication in 2005. Here, finally, it is brought to English-language readers. At its heart is a question central to both anthropology and philosophy: what is the relationship between nature and culture?Culture—as a collective human making, of art, language, and so forth—is often seen as essentially different from nature, which is portrayed as a collective of the nonhuman world, of plants, animals, geology, and natural forces. Descola shows this essential difference to be, however, not only a specifically Western notion, but also a very recent one. Drawing on ethnographic examples from around the world and theoretical understandings from cognitive science, structural analysis, and phenomenology, he formulates a sophisticated new framework, the “four ontologies”— animism, totemism, naturalism, and analogism—to account for all the ways we relate ourselves to nature. By thinking beyond nature and culture as a simple dichotomy, Descola offers nothing short of a fundamental reformulation by which anthropologists and philosophers can see the world afresh.
From the founder of the Climate Outreach and Information Network, a groundbreaking take on the most urgent question of our time: Why, despite overwhelming scientific evidence, do we still ignore climate change? “Please read this book, and think about it.” --Bill NyeMost of us recognize that climate change is real, and yet we do nothing to stop it. What is this psychological mechanism that allows us to know something is true but act as if it is not? George Marshall's search for the answers brings him face to face with Nobel Prize-winning psychologists and the activists of the Texas Tea Party; the world's leading climate scientists and the people who denounce them; liberal environmentalists and conservative evangelicals. What he discovered is that our values, assumptions, and prejudices can take on lives of their own, gaining authority as they are shared, dividing people in their wake. With engaging stories and drawing on years of his own research, Marshall argues that the answers do not lie in the things that make us different and drive us apart, but rather in what we all share: how our human brains are wired-our evolutionary origins, our perceptions of threats, our cognitive blindspots, our love of storytelling, our fear of death, and our deepest instincts to defend our family and tribe. Once we understand what excites, threatens, and motivates us, we can rethink and reimagine climate change, for it is not an impossible problem. Rather, it is one we can halt if we can make it our common purpose and common ground. Silence and inaction are the most persuasive of narratives, so we need to change the story. In the end, Don't Even Think About It is both about climate change and about the qualities that make us human and how we can grow as we deal with the greatest challenge we have ever faced.
BACKGROUND: Chronic work-related stress is an independent risk factor for cardiometabolic diseases and associated mortality, particularly when compounded by a sedentary work environment. The purpose of this study was to determine if an office worksite-based hatha yoga program could improve physiological stress, evaluated via heart rate variability (HRV), and associated health-related outcomes in a cohort of office workers. METHODS: Thirty-seven adults employed in university-based office positions were randomized upon the completion of baseline testing to an experimental or control group. The experimental group completed a 10-week yoga program prescribed three sessions per week during lunch hour (50 min per session). An experienced instructor led the sessions, which emphasized asanas (postures) and vinyasa (exercises). The primary outcome was the high frequency (HF) power component of HRV. Secondary outcomes included additional HRV parameters, musculoskeletal fitness (i.e. push-up, side-bridge, and sit & reach tests) and psychological indices (i.e. state and trait anxiety, quality of life and job satisfaction). RESULTS: All measures of HRV failed to change in the experimental group versus the control group, except that the experimental group significantly increased LF:HF (p = 0.04) and reduced pNN50 (p = 0.04) versus control, contrary to our hypotheses. Flexibility, evaluated via sit & reach test increased in the experimental group versus the control group (p /=70% of yoga sessions (n = 11) to control (n = 19) yielded the same findings, except that the high adherers also reduced state anxiety (p = 0.02) and RMSSD (p = 0.05), and tended to improve the push-up test (p = 0.07) versus control. CONCLUSIONS: A 10-week hatha yoga intervention delivered at the office worksite during lunch hour did not improve HF power or other HRV parameters. However, improvements in flexibility, state anxiety and musculoskeletal fitness were noted with high adherence. Future investigations should incorporate strategies to promote adherence, involve more frequent and longer durations of yoga training, and enrol cohorts who suffer from higher levels of work-related stress.

Sex offenders are thought to suffer from deficits in their capacity to experience empathy, and this is considered to be important in the development, and particularly the maintenance, of their deviant behaviour. The concept of empathy, however, is confused. A multicomponent staged model of empathy is outlined, and it is suggested that empathy deficits may be more person-specific than has previously been thought. The evidence concerning empathy deficits in sex offenders is considered, and it is concluded that our multicomponent model offers a better way to understand and treat the empathy deficits in these men.
Inhalation of 7.5% carbon dioxide increases anxiety and autonomic arousal and provides a novel experimental model of anxiety with which to evaluate pharmacological and psychological treatments for anxiety. To date several psychotropic drugs including benzodiazepines, SSRIs and SNRIs have been evaluated using the 7.5% CO2 model; however, it has yet to be used to evaluate psychological interventions. We compared the effects of two core psychological components of mindfulness-meditation (open monitoring and focused attention) against general relaxation, on subjective, autonomic and neuropsychological outcomes in the 7.5% CO2 experimental model.32 healthy screened adults were randomized to complete 10 min of guided open monitoring, focused attention or relaxation, immediately before inhaling 7.5% CO2 for 20 min. During CO2-challenge participants completed an eye-tracking measure of attention control and selective attention. Measures of subjective anxiety, blood pressure and heart rate were taken at baseline and immediately following intervention and CO2-challenge.
OM and FA practice reduced subjective feelings of anxiety during 20-min inhalation of 7.5% CO2 compared to relaxation control. OM practice produced a strong anxiolytic effect, whereas the effect of FA was more modest. Anxiolytic OM and FA effects occurred in the absence of group differences in autonomic arousal and eye-movement measures of attention.
Our findings are consistent with neuropsychological models of mindfulness-meditation that propose OM and FA activate prefrontal mechanisms that support emotion regulation during periods of anxiety and physiological hyper-arousal. Our findings complement those from pharmacological treatment studies, further supporting the use of CO2 challenge to evaluate future therapeutic interventions for anxiety.

Palaeontologists characterize mass extinctions as times when the Earth loses more than three-quarters of its species in a geologically short interval, as has happened only five times in the past 540 million years or so. Biologists now suggest that a sixth mass extinction may be under way, given the known species losses over the past few centuries and millennia. Here we review how differences between fossil and modern data and the addition of recently available palaeontological information influence our understanding of the current extinction crisis. Our results confirm that current extinction rates are higher than would be expected from the fossil record, highlighting the need for effective conservation measures.
OBJECTIVE:The aim of this study was to evaluate the effects of an 8-week Mindfulness-Based Stress Reduction course (MBSR) on people with Parkinson's disease who experienced depression, anxiety, stress or difficulty coping with Parkinson's.
METHODS:
Thirteen participants were recruited and six completed the full MBSR course. Data were analysed using repeated measures analysis of variance and thematic analysis.
RESULTS:
There were significant improvements in levels of depression, anxiety and stress at weeks eight and sixteen, as measured by the Depression Anxiety and Stress Scale, short version (DASS-21). Themes of 'mindfulness as challenging' and 'mindfulness as life-enhancing' were identified from follow-up questionnaire responses. All participants reported they would recommend MBSR to other people with Parkinson's.
CONCLUSION:
This study supports previous preliminary findings that mindfulness-based interventions could benefit people with Parkinson's experiencing non-motor symptoms. Further research using larger sample sizes, a control group, and a longer follow-up period is required.

An introduction to the philosophy and the basic positions of hatha yoga.
CONTEXT:Current therapies for traumatic brain injury (TBI) include pharmacotherapy, psychotherapy, and cognitive rehabilitation. Unfortunately, psychological and emotional issues regularly go untreated in individuals with TBI even after they receive treatment for physical, behavioral, and cognitive issues. Mindfulness-based cognitive therapy (MBCT) may offer new rehabilitation opportunities for individuals with TBI.
OBJECTIVE:
To demonstrate the efficacy of MBCT in the treatment of clinically diagnosed depression in a TBI population.
DESIGN:
The research team measured depression, pain frequency and intensity, energy levels, health status, and function preintervention and postintervention.
SETTING:
The research team conducted the study at the Ottawa Hospital Rehabilitation Centre, Ontario, Canada.
PARTICIPANTS:
The research team recruited 23 participants from two sources: (1) the brain injury program at the hospital and (2) the local head-injury association. Twenty participants completed the study.
INTERVENTION:
The intervention was 8 weeks in length, with a 90-minute MBCT session once a week. The research team based the specific content of the study's intervention on a combination of Kabat-Zinn's manualized mindfulness-based stress reduction program and Segal and colleague's manual for MBCT.
OUTCOME MEASURES:
The research team determined statistical significance using paired t-tests for continuous outcomes and the McNemar chi-square test for dichotomous categorical outcomes. They also calculated effect sizes for all depression measures.
RESULTS:
Postintervention, the study found that MBCT significantly reduced (P < .050) depression symptoms on all scales compared to baseline. The study demonstrated medium to large effect sizes for each depression measure. Participants indicated reduced pain intensity (P = .033) and increased energy levels (P = .004). No significant changes occurred in anxiety symptoms, pain frequency, and level of functioning postintervention.
CONCLUSION:
MBCT was efficacious in reducing depression in the TBI population, providing ample rationale for further research with more robust designs. This study marks an important step toward the development and provision of MBCT on a wider scale to support the rehabilitation efforts of people who have depression symptoms following TBI.

OBJECTIVE:We sought to determine if we could reduce symptoms of depression in individuals with a traumatic brain injury using mindfulness-based cognitive therapy.
SETTING:
The study was conducted in a community setting.
PARTICIPANTS:
We enrolled adults with symptoms of depression after a traumatic brain injury.
DESIGN:
We conducted a randomized controlled trial; participants were randomized to the 10-week mindfulness-based cognitive therapy intervention arm or to the wait-list control arm.
MAIN MEASURES:
The primary outcome measure was symptoms of depression using the Beck Depression Inventory-II.
RESULTS:
The parallel group analysis revealed a greater reduction in Beck Depression Inventory-II scores for the intervention group (6.63, n = 38,) than the control group (2.13, n = 38, P = .029). A medium effect size was observed (Cohen d = 0.56). The improvement in Beck Depression Inventory-II scores was maintained at the 3-month follow-up.
CONCLUSION:
These results are consistent with those of other researchers that use mindfulness-based cognitive therapy to reduce symptoms of depression and suggest that further work to replicate these findings and improve upon the efficacy of the intervention is warranted.

This study reports on the findings of a qualitative evaluation of a yoga intervention program for urban middle and high school youth in New York City public and charter schools. Six focus groups were conducted with students who participated in a year-long yoga program to determine their perceptions of mental and physical benefits as well as barriers and challenges. Results show that students perceived the benefits of yoga as increased self-regulation, mindfulness, self-esteem, physical conditioning, academic performance, and stress reduction. Barriers and challenges for a yoga practice include lack of time and space. The extent to which the benefits experienced are interrelated to one another is discussed. Suggestions for future research and school-based programming are also offered.
Through their collective experience working in service learning and civic education, Welch and Koth present a scholarly approach to examining the parallels between spiritual formation and service learning as it relates to college student development.
OBJECTIVES: We conducted a quality improvement project to determine (1) what information providers and patients most wanted to learn about complementary and integrative health (CIH) therapies and (2) in what format they wanted to receive this information. The overall aim was to develop educational materials to facilitate the CIH therapy decision-making processes. DESIGN: We used mixed methods to iteratively pilot test and revise provider and patient educational materials on yoga and meditation. We conducted semistructured interviews with 11 medical providers and held seven focus groups and used feedback forms with 52 outpatients. We iteratively developed and tested three versions of both provider and patient materials. Activities were conducted at four Veterans Administration medical facilities (two large medical centers and two outpatient clinics). RESULTS: Patients want educational materials with clearly stated basic information about: (1) what mindfulness and yoga are, (2) what a yoga/meditation class entails and how classes can be modified to suit different abilities, (3) key benefits to health and wellness, and (4) how to find classes at the hospital/clinic. Diverse media (videos, handouts, pocket guides) appealed to different Veterans. Videos should depict patients speaking to patients and demonstrating the CIH therapy. Written materials should be one to three pages with colors, and images and messages targeting a variety of patients. Providers wanted a concise (one-page) sheet in black and white font with no images listing the scientific evidence for CIH therapies from high-impact journals, organized by either type of CIH or health condition to use during patient encounters, and including practical information about how to refer patients. CONCLUSIONS: Providers and patients want to learn more about CIH therapies, but want the information in succinct, targeted formats. The information learned and materials developed in this study can be used by others to educate patients and providers on CIH therapies.
BACKGROUND: Recent studies have highlighted the role of right-sided anterior temporal and prefrontal activation during anxiety, yet no study has been performed with social phobics that assesses regional brain and autonomic function. This study compared electroencephalograms (EEGs) and autonomic activity in social phobics and controls while they anticipated making a public speech.
METHODS: Electroencephalograms from 14 scalp locations, heart rate, and blood pressure were recorded while 18 DSM-IV social phobics and 10 controls anticipated making a public speech, as well as immediately after the speech was made. Self-reports of anxiety and affect were also obtained.
RESULTS: Phobics showed a significantly greater increase in anxiety and negative affect during the anticipation condition compared with controls. Heart rate was elevated in the phobics relative to the controls in most conditions. Phobics showed a marked increase in right-sided activation in the anterior temporal and lateral prefrontal scalp regions. These heart rate and EEG changes together accounted for > 48% of the variance in the increase in negative affect during the anticipation phase.
CONCLUSIONS: These findings support the hypothesis of right-sided anterior cortical activation during anxiety and indicate that the combination of EEG and heart rate changes during anticipation account for substantial variance in reported negative affect.

This introduction to the focus section on “Writing the Anthropocene” examines the challenges that the entry of our species into a new geological epoch poses for the humanities in general and for literary and media theory in particular. It proposes the hypothesis that the Anthropocene can best be understood as a form of writing, a process by which humankind inscribes permanent messages into the geological, climatological, and biochemical records of our planet and is forced, in turn, to study those records for messages pertaining to its future. It discusses the relationship of the Anthropocene to the wider discourse of posthumanism and also touches upon the importance of speculative realism as well as genres like the science-fiction novel to help us conceptualize our new condition. A brief summary of each of the ten essays in the focus section follows.
Middle adolescents (15–17 years old) are prone to increased risk taking and emotional instability. Emotion dysregulation contributes to a variety of psychosocial difficulties in this population. A discipline such as yoga offered during school may increase emotion regulation, but research in this area is lacking. This study was designed to evaluate the impact of a yoga intervention on the emotion regulation of high school students as compared to physical education (PE). In addition, the potential mediating effects of mindful attention, self-compassion, and body awareness on the relationship between yoga and emotion regulation were examined. High school students were randomized to participate in a 16-week yoga intervention (n=19) or regular PE (n=18). Pre-post data analyses revealed that emotion regulation increased significantly in the yoga group as compared to the PE group (F (1,32) = 7.50, p = .01, and eta2 = .19). No significant relationship was discovered between the changes in emotion regulation and the proposed mediating variables. Preliminary results suggest that yoga increases emotion regulation capacities of middle adolescents and provides benefits beyond that of PE alone.
Yoga programs within schools have become more widespread but research regarding the potential effect on academic achievement remains limited. This study cluster-randomized 112 students within a single New York City public high school to participate in either school-based yoga or physical education (PE) for an entire academic year. The primary outcome was mean annual grade point average (GPA). Psychosocial variables (self-regulation, executive function, well-being, and mindfulness) were examined as mediators. The study's primary hypothesis that yoga would improve academic performance was not supported by intent to treat analysis; however, a significant interaction was observed between class assignment and class participation. Among students with higher participation, those assigned to yoga classes had a significantly higher GPA. For example, at 49 classes of participation for both groups, students assigned to yoga classes had an estimated 2.70 higher mean GPA (effect size = 0.31) than students assigned to PE.
